Abstract:

The aim of the current research program was to investigate the social context of escalation in response to continued pushy behaviour in the workplace. In doing so, this research program contributes to the development of communication skills by investigating the entire context of skills required for effective communication in managing everyday conflict in the workplace. The response class, Responding to continued pushy or dominating behaviour in the workplace, was selected as a vehicle for examining the context of escalation for two reasons. Firstly, this response class, by the very nature of pushy behaviour, embodies a continued interaction. In the past, assertive communication research has focused on one off responses rather than a continued interaction. Secondly, this response class has been identified in previous research as being of interest to assertiveness trainees (Cooley, 1979, Lefevre & West, 1984, Wilson & Gallios, 1993). The theoretical premise of the current research program resides in the application of Social Rules Theory to the difficult face-to-face communication situation, or response class, of responding to continued pushy behaviour in the workplace. In doing so, this approach also takes into account dialectical theory, conflict resolution theory, and the concept of response components that can be selected and/or combined in order to meet the requirements, or rules, of a specific situation. In adopting the Social Rules approach, the current research program addresses the key criticisms of the traditional approach to assertion and assertion training, namely that people behaving assertively are sometimes negatively evaluated for assertive behaviour (Wilson & Gallois, 1993); and that assertion traditionally focused on the expressiveness of a response at the unintended cost of social or contextual appropriateness (Crawford, 1988); that finding a response is assertive does not delineate which aspects of the response are producing which types of effects (Galassi, 1978; Mullinix & Galassi, 1981). Most importantly, the current research contributes to the field by examining the negative response class in terms of a response sequence of escalation, rather than a one-off response. This is new research and contributes to the field theoretically and to the conceptualisation of assertion and communication. In order to meet the goals of the current research program, the response class Responding to continued pushy behaviour in the workplace, was defined precisely in terms of the situational context. This response class implies a workplace relationship of an ongoing nature. Four other variables were involved in defining and investigating the situation. These were status, gender of message sender, gender of message receiver, and response level (initial response, first escalation or second escalation). The current program of research was carried out in a series of three related studies, and these four variables were examined in each of the three studies. The purpose of the first study was to elicit social rules and goals for interpersonally effective and appropriate escalation strategies in response to pushy dominating communication in the workplace. This study was conducted in two parts, a qualitative questionnaire completed by 20 females and 20 males, and two focus groups, one for females and one for males. Content analysis revealed a set of rules for an escalation sequence for each combination of status and gender. These rules were then operationalized, filmed and analysed in the second study. One hundred and twenty-three participants (64 females and 59 males) with work experience watched the operationalized responses and rated them on a series of seven scales. These scales were effectiveness in stopping the pushy behaviour (task effectiveness), effectiveness in maintaining the relationship (maintenance effectives), social appropriateness, interpersonal skill required, risk involved, personal difficulty in making the response, and likelihood of making the response. Analyses included descriptive statistics, which indicated that the operationalized responses were perceived to be effective and socially appropriate. Multivariate Analysis of Variance (MANOVA) were also conducted and revealed a number of significant interactions for each status level (manager, colleague, subordinate). The third and final study in this research program adopted a qualitative approach to examine continued pushy or dominating communication in the workplace. Eighty-two (45 female and 37 male) participants completed a qualitative questionnaire utilizing an open-ended approach. This questionnaire was designed for the purpose of the third study to elicit the typical behaviours, emotions and cognitions participants have in response to continued pushy behaviour in the workplace. Also, a data analysis process was designed specifically for the third study to provide an analytical procedure that was as systematically rigorous and replicable as possible. This process is explained in detail in Study 3. The results of the third study revealed differences between actual behaviour and rule based behaviour in response to continued pushy behaviour, namely that actual responses are more public and direct in nature, and more likely to promote destructive conflict escalation. This finding implies that typical responses are not as effective as rule based responses, highlighting the benefits of applying social rules to manage difficult face to face communication situations. In summary, the current research project utilized a multi-method approach in a series of three studies to reveal the nature of Social Rules based responses and typical responses. The results of this research program have implications for both the theory and practice of effective communication and effective communication training. Evaluation of both social rules based and typical responses have implications for communication trainees who wish to make informed choice based on a consideration of functionally effective behaviour and personal satisfaction. For example, social rules for escalation in response to continued pushy behaviour from a male manager may indicate that it is most effective for a female subordinate to acquiesce. However, the female subordinate may choose to violate social rules and risk being perceived as inappropriate and damaging the relationship, to achieve a super-ordinate goal or for personal satisfaction. Conversely, the social rules and responses developed in the current research program have implications for professional effectiveness in the workplace by providing guidelines for dealing with dominating behaviour.

Abstract:

La presente tesi tratta il comportamento meccanico delle fasce di piano in muratura composite. Con tale termine ci si riferisce alle fasce di piano che hanno al di sotto un elemento portante in conglomerato cementizio armato, come ad esempio cordoli o solai. Assieme ai maschi murari, le fasce di piano costituiscono gli elementi portanti di una parete in muratura. Tuttavia, in caso di analisi sismica di un edificio in muratura, l’effetto fornito da tali elementi è trascurato e si considera solamente il contributo dei maschi murari. Ciò è dovuto anche alla scarsa conoscenza che ancora oggi si possiede sul loro comportamento meccanico. Per questo motivo diversi gruppi di ricerca tutt’ora sono impegnati in tale studio. In particolare, il lavoro di questa tesi, s’inserisce nel più ampio progetto di ricerca condotto dalla professoressa Katrin Beyer, direttrice del Laboratorio di Ingegneria Sismica e Dinamica Strutturale del Politecnico di Losanna (Svizzera).

Abstract:

This thesis investigates the torsional performance of steel structures with and without rigid diaphragm constraints through numerical simulations and evaluates the appropriateness of relevant design provisions in current seismic design codes. In the first part of the work, six theme structures with different (1) in-plane stiffness of diaphragm, and (2) horizontal configurations of vertical braced frames were designed and their performance evaluated through both nonlinear static and dynamic analyses. Comparisons of the analytical results between the structures with and without rigid diaphragm constraints indicate that the in-plane rigidity of the diaphragms affects the efficiency of in-plane force transfer mechanisms, resulting in different global ductility and strength demands. Rigid diaphragm structures exhibit higher global strengths as well as higher torsional rotation capacity because of the infinite in-plane stiffness of the diaphragm. Semi-rigid diaphragm structures have higher ductility demands due to the finite in-plane diaphragm stiffness. The inclusion of bi-axial forces in the analyses reduces the structural strength and increases the ductility demands on the peripheral frames. The axial forces in the collectors and chords that make up the diaphragm depend on (1) the sequence of brace buckling and (2) vertical configuration of the braced frames. The results show higher axial forces in collectors in the roof diaphragms, and higher chord axial forces in the third floor diaphragms. The shear connections in the beams that make up both the collectors and chords are susceptible to failure due to the significant increment of axial forces in those members. The conventional beam analogy used in design can severely underestimate the axial forces in chords and collectors when the structures step into the inelastic stage.

Abstract:

The research presented in this thesis is to evaluate the feasibility of demountable shear connectors as an alternative to welded shear connectors in composite structures through push off tests and composite beam tests. Push off tests were conducted to examine the shear strength, stiffness and ductility of demountable shear connectors in composite structures. The experimental results showed that demountable shear connectors in composite structures have very similar shear capacity to welded shear connectors. The shear capacity was compared against the prediction methods used for the welded shear connections given in Eurocode 4 and AISC 360-10 and the methods used for bolted connections in Eurocode 3 and ACI 318-08. It was found that the AISC 360-10 and ACI 318-08 methods overestimated the shear capacity in some cases. The Eurocode method is conservative and can be utilised to predict the shear capacity of demountable connectors in composite structures. The experimental studies of two identical composite beams using demountable shear connectors and welded shear connectors showed very similar moment capacity. However, the specimen with demountable shear connectors was more ductile compared to the welded specimen. The experimental study suggests that the methods available in Eurocode 4 and BS 5950 for predicting moment capacity and mid span deflection can be adopted for composite beam with demountable shear connectors. In addition, a finite element analysis of push off test and beam test with demountable shear connectors was also conducted for parametric studies and results are used to evaluate the behaviour of composite structures.

Abstract:

The behavior and strength of welded shear studs are subjects of ongoing study. In recent years, research has shown that the American Institute of Steel Construction (AISC) specification equations for shear stud strength are unconservative for studs placed in deck with ribs transverse to the steel beam. Twenty-four solid slab push-out tests, 93 composite slab push-out tests, and bare stud tests were performed to study the effects on stud strength of friction, normal load, position of studs in the ribs of steel deck, concrete strength, and stud properties. Stud diameters ranged from 3/8 in. to 7/8 in., deck heights ranged from 2 in. to 6 in., and both single and pairs of studs were tested. The push-out test results from this study were combined with other studies to propose a new stud strength prediction model. Three new beam tests were performed to study the effect of the stud position in the ribs of the steel deck. The results of these tests, along with 61 other beam tests, were used to verify the new stud strength prediction model. A reliability study was performed to determine resistance factors for stud strength and beam strength.

Abstract:

The main inquiry for this research is to identify the reasons that contribute to customer switching intention decisions. In addressing this enquiry, two theories - the theory of migration and theory of planned behaviour - were identified as the theoretical framework underpinning the study. Two main objectives of the study were (i) to identify the push-pull and mooring factors and (ii) to measure the relationship between the push-pull and mooring factors towards switching intention. The investigation focused on the impact of with push-pull-mooring factors on switching intention. Early research into switching behaviour studies focused largely on variables that contribute to the switching intention decision, mainly due to the critical incidents encountered by customers that push them from their origin or pull them to another destination or mooring factors that might inhibit or mitigate their switching decision. In view of this, a combination of push-pull and mooring variables were used to measure the switching intention behaviour. A multiple method approach was used to study the issues in two different stages. In the first stage qualitative data collection was used to support and confirm the identification of factors from the literature. For the main quantitative methods, using a hypothetical deductive testing approach, this study (N=2018) used survey data collected via a self-administered, voluntary online survey, to develop switching intention behaviour model. The results indicated that situational factors, positive attachments, perceived switching benefits, positive attitudes towards switching and positive beliefs of others towards switching emerged as consistent push factor while availability of alternatives emerged as the pull factors. Interestingly poor pricing, poor service incidents, positive ability to switch and switching barriers were not supported in this study indicating that there is no relationship between poor pricing, poor service incidents, positive ability to switch and switching barriers towards switching intention.

Abstract:

Mestrado em Marketing
A adoção de dispositivos móveis no mundo presenciou um aumento exponencial nos últimos anos, o que também se refletiu no número de aplicações móveis, ou apps. Muitas empresas desenvolveram suas próprias apps para exibir suas entidades de marca e começaram a usá-las como um canal de marketing direto com notificações push, mensagens exibidas no ecrã do dispositivo móvel. Esta pesquisa procura compreender a dimensão do impacto no comportamento de compra das notificações push enviadas por aplicações de marca das redes de supermercados portuguesas. Além disso visa segmentar os resultados para diferentes grupos de compradores com base em variáveis psicográficas. Esta pesquisa foi realizada adotando-se uma abordagem quantitativa e amostragem não probabilística. Com um questionário online, foram coletados de 265 respostas, que foram tratadas com procedimentos estatísticos, como análise descritiva, multivariada e de cluster. As descobertas confirmam que os clientes que receberam notificações push têm uma média superior nos gastos mensais nos supermercados, em comparação com os clientes com aplicativos de marca que não receberam nenhuma notificação push. Entretanto, esses resultados foram observados apenas nos compradores envolvidos profundamente em todos os atributos da compra e nos compradores com uma maior preocupação com os produtos. Academicamente, esta dissertação contribui para a discussão sobre notificações push como um canal de marketing direto e sobre os efeitos das características do cliente no efeito do marketing direto. Essa investigação também oferece informações para o profissional de marketing, afirmando que as notificações por push podem ser usadas para impulsionar compras offline dos usuários.
Mobile adoption has seen an exponential increase worldwide in recent years, which has also been reflected in the number of mobile applications, or apps. Many companies have developed their own apps to display their brand entities and have started using them as a direct marketing channel with push notifications, messages displayed on their mobile device screen. This research seeks to understand the extent of the impact on purchasing behavior of push notifications sent by branded applications from Portuguese supermarket chains. It also aims to segment the results to different buyer groups based on psychographic variables. This research was conducted by adopting a quantitative approach and non-probabilistic sampling. With an online questionnaire, 265 responses were collected and treated with statistical procedures such as descriptive, multivariate and cluster analysis. The findings confirm that customers who received push notifications had a higher average monthly spend in supermarkets than customers with branded apps who received no push notifications. However, these results were observed only for buyers deeply involved in all attributes of the purchase and for buyers with a greater concern for the products. Academically, this dissertation contributes to the discussion of push notifications as a direct marketing channel and the effects of customer characteristics on the effect of direct marketing. This research also provides insight to the marketer, stating that push notifications can be used to drive users' offline purchases.

Abstract:

This thesis takes the reader on an exploratory journey into the development of impulse purchasing behaviour stemming from the increased usage of web-connected smartphones. At an unprecedented rate, consumers are able to access businesses online, twenty-four hours a day, seven days a week, at their own convenience, without restrictions other than a connection to the World Wide Web. This mobile phenomenon has effectively pushed the commercial market to new boundaries and simultaneously created new possibilities for retailers to reach out to consumers by providing seamless and innovative marketing solutions on portable devices to a fast-growing market segment. This emergent technology and the trends it brings with it, demands special attention to the analysis of consumer behaviourism. As of date, academia has put relatively little emphasis on the evolution of impulse purchasing behaviour as a product of smartphone usage. In this paper, the authors investigate the attitude of local consumers towards so-called ‘push notifications’, whose purpose is to stimulate an impulsive behaviour in the smartphone user. The results of this study show that multiple factors in relation to push notifications on smartphones play an important part in shaping the attitude of consumers and furthermore can elicit impulse buying behaviour. These factors often bridge each other and are at times mutually dependent.

Full text

Abstract:

Steel plate shear walls (SPSWs) are a lateral force resisting system consisting of thin infill steel plates surrounded by boundary frame members. The infill steel plates are allowed to buckle in shear and subsequently form diagonal tension field actions during earthquake events. Hysteretic energy dissipation of this system is primarily achieved through yielding of the infill plates. Conceptually, in a SPSW system with ideally rigid columns pinned to ground, the infill plates at different stories will yield simultaneously as a result of the lateral loads. However, when the columns become flexible, infill plate yielding may initially occur at one story and progressively spread into the other stories with increasing roof displacement. This research investigates the effect of column stiffness on infill plate yielding sequence and distribution along the height of steel plate shear walls subjected to earthquake forces. Analytical models are derived and validated for two-story SPSWs. Based on the derived model, probabilistic simulations are conducted to calculate the probability of achieving infill plate yielding in both stories before occurrence of a premature failure caused by excessive inter story drift at the initially yielded story. A total of three simulation methods including the Monte-Carlo method, the Latin Hypercube sampling method, and the Rosenblueth’s 2K+1 point estimate method were considered to account for the uncertain infill plate thickness and lateral force distributions in the system.The investigation is also extended to multi-story SPSWs. Three example six-story SPSWs are evaluated using the Rosenblueth's 2K+1 point estimation method which is identified to be most efficient from the simulation on two-story SPSWs. Moreover, the effectiveness of the column minimum moment of inertia required in the current code for achieving infill plate yielding at every story of SPSWs is evaluated.

Abstract:

Background: la Sindrome della Spinta è un quadro clinico conseguente a danno cerebrale destro o sinistro, a seguito del quale i soggetti spingono attivamente con il lato non paretico verso quello patologico, determinando la perdita dell’allineamento posturale sulla verticale mediana. Questi soggetti si oppongono a qualsiasi tentativo di correzione passiva della loro postura. La complessità dei sintomi che stanno alla base della Sindrome della Spinta comporta importanti ricadute sulla qualità della vita di questi soggetti e, di conseguenza, dei loro caregiver. Obiettivo: l’obiettivo di questa Scoping Review è quello di riassumere un corpus di conoscenze eterogeneo presente in Letteratura riguardo ai meccanismi neuropsicologici e agli aspetti neurofisiologici che stanno alla base della Sindrome della Spinta, al fine di fornire la conoscenza clinica necessaria per poter elaborare il programma di trattamento più efficace. Metodi: la ricerca è avvenuta consultando due banche dati online, PubMed e CINHAL, tramite una ricerca manuale bibliografica. Sono stati poi analizzati gli articoli pertinenti rispetto al quesito di partenza “Cosa ci dice la Letteratura in merito alle correlazioni tra la Sindrome della Spinta e gli aspetti clinici, neuropsicologici e neurofisiologici?”, prendendo in considerazione ogni tipologia di studio nella fascia temporale tra il 2010 e il 2021, senza imporre limiti di lingua Risultati: sono stati selezionati 12 articoli, di cui 4 revisioni narrative, 4 studi retrospettivi, 2 trial clinici, 1 studio prospettico e 1 case-report. Il processo di selezione degli articoli è stato riportato utilizzando un diagramma di flusso, mentre i contenuti dei singoli articoli sono stati schematizzati in una tabella sinottica. Conclusioni: dall’analisi attuale della Letteratura emerge come non sia una causa singola e specifica a determinare la Sindrome della Spinta, ma più fattori di tipo neurofisiologico, neuroanatomico e neuropsicologico.

Abstract:

Purpose: The purpose of this study is to increase the understanding of what makes Swedish millennials follow and unfollow influencers on Instagram. Metod: This study had a deductive and qualitative approach and has collected data through twelve semi-structured interviews. Conclusion: This study concludes that millennials mainly follow influencers on Instagram to get inspiration for their own lives. One of the most common reasons why millennials are unfollowing influncers on Instagram is that influencers tend to publish too much content, which leads to information overload. Millennials also unfollow influencers due to the fact that their posts no longer appeal to them because they changed preferences or because influencers shift the focus of their content. This study also concluded that there is nothing that inhibits a millennial from unfollowing an influencer on Instagram other than the fact that it takes a little bit of effort to visit the account and press the unfollow button.
Syfte: Syftet är att öka förståelsen för vad som får svenska millennials att följa respektive avfölja influencers påInstagram. Metod: Den här studien har haft en deduktiv och kvalitativ karaktär och har samlat in data genom tolv semi-strukturerade intervjuer. Slutsats: Den här studien drar slutsatsen av att millennials främst följer influencers på Instagram för att få inspiration till sina egna liv. En av de vanligaste orsakernatill att millennials avföljer influncers på Instagram äratt influencerstenderar att publicera för mycket inlägg vilket leder till en informationsöverbelastning.Millennials avföljer också influencers för att deras inlägg inte längre tilltalar dem på grund av att de bytt preferenser eller att influencers bytt inriktning på sitt innehåll. Den här studien drar också slutsatsen att det finns egentligen inget som hämmar en millennial från att avfölja en influencer på Instagram annat än att de upplever det som tids-och energikrävande att gå in och avfölja.

Torna-se, pois, imprescindível para a Destination Marketing Organisation (DMO) conhecer o perfil dos turistas atraídos por tais eventos e compreender as motivações turísticas inerentes à participação nos mesmos. Como tal, a presente investigação debruça-se sobre a compreensão e clarificação das razões e motivações que impelem os turistas a visitar a Ilha da Madeira no decorrer da Festa da Flor, recorrendo ao framework conceptual Push e Pull. A metodologia utilizada neste estudo foi de natureza descritiva-explanatória, tendo por base uma abordagem quantitativa, com recurso à aplicação de um inquérito por questionário a 281 turistas, nas principais avenidas da cidade do Funchal, no decorrer da Festa da Flor, edição 2019. Os resultados evidenciam que os Gestores do Destino Madeira devem dar especial atenção aos fatores motivacionais internos (push): Escape / Fuga à rotina, Relaxe, Prestígio, União Familiar, Novidade / Conhecimento e Entretenimento, e aos fatores motivacionais externos (pull): Eventos Especiais, Condições Básicas e Naturais do Destino, Gastronomia e Exploração Cultural e Histórica. Por outro lado, os resultados demonstram que o evento especial em estudo, a Festa da Flor, não é o polo de atração que desencadeia o desejo de visitar a Ilha da Madeira. É, antes, encarado como um fator suplementar, uma oferta turística complementar posta à disposição dos visitantes.
Event creation and organization are key elements in the diversification strategy of any tourist destination. Some events are indeed major catalysts for the economic, social, cultural and political development of a country, city or region. It is therefore essential for the Destination Marketing Organization (DMO) to know the profile of tourists attracted by such events and to understand the tourist motivations inherent in their participation. As such, this research focuses on understanding and clarifying the reasons and motivations that drive tourists to visit Madeira Island during the Flower Festival, using the Push and Pull conceptual framework. The methodology used in this study was descriptive and explanatory, based on a quantitative approach, using a questionnaire survey to 281 tourists, in the main avenues of Funchal, during the Festa da Flor, 2019 edition. The results show that the Destination Managers of Madeira should pay particular attention to the internal motivational factors (push): Escape / Routine Escape, Relax, Prestige, Family Union, Novelty / Knowledge and Entertainment, and the external motivational factors (pull): Special Events, Basic and Natural Destination Conditions, Gastronomy and Cultural and Historical Exploration. On the other hand, the results show that the special event under study, the Flower Festival, is not the attraction that triggers the desire to visit the island. Rather, it is seen as a supplementary factor, a complementary tourism offer made available to visitors.

Abstract:

La détermination des comportements mécaniques des murs en pisé est d’une importance capitale dans un contexte où il y a un regain d’intérêt pour l’utilisation de matériaux de construction à très faible impact environnementaux. D’une part, cette étude contribue à trouver des moyens appropriés pour la conservation et la restauration du patrimoine bâti et, d’autre part, permet d’établir de nouvelles recommandations pour la conception de nouvelles structures en pisé dans le respect des règlements de la construction (réglementation thermique et réglementation parasismique).Dans ce contexte, cette thèse étudie le comportement des murs en pisé soumis à des sollicitations horizontales. Quatre murs de terre en pisé non stabilisés ont été testés sous une combinaison de charge verticale et horizontale monotone (type pushover) jusqu'à la rupture. Le comportement au cisaillement et les modes de ruptures de ces murs sont étudiés à l’aide d’une technique de corrélation d’images à grande échelle. Les résultats ont montré que le pisé est caractérisé par un comportement mécanique non linéaire très significatif et une ductilité remarquable. D’une manière générale, les murs ont subi une rupture de cisaillement due à une fissuration principale au niveau de la bielle de compression. Des fissures à l'interface entre les différentes couches ont également été observées.L'évaluation de la performance de ces murs a été effectuée sur la base de la méthodologie pushover. Le travail expérimental a été complété avec la détermination des caractéristiques mécaniques du matériau pisé en compression puis une étude en cisaillement directe (cohésion et angle de frottement) à l’aide de deux boites de Casagrande de tailles différentes. Enfin, l’importance de ces paramètres a été analysée en réalisant des simulations numériques à l’échelle du mur
Determining the mechanical behavior of rammed earth walls is a highly important feature giving that there is a renewed interest in the use of the natural material in building construction. On one hand, it contributes to finding suitable and appropriate ways for the conservation and restoration of these building and on another hand, it draws new recommendations for the conception of new rammed earth structures with respect to new building regulations (earthquake building guideline, new thermal regulation).In this context, this thesis investigates the behavior of rammed earth walls subjected to lateral loading. Four unstabilized rammed earth walls were tested under a combination of vertical and monotonic pushover tests up to failure. The shear behavior of these walls is studied along with the failure modes by means of digital image correlation. Results showed that the response of the rammed earth is characterized by significant non-linear behavior with a remarkable ductility. In general, the walls experienced a shear failure due to the failure of diagonal struts. Cracks at the interface between the bottom layers were also observed.The performance of these walls was assessed based on the pushover methodology. The experimental work was completed with the determination of the mechanical characteristics of rammed earth in compression and an investigation of the shear components: cohesion and friction angle of the rammed earth through shear box tests on a different scale. Finally, the relevance of these parameters was tested by performing a numerical model that aims to simulate the experimental tests done on the scale of the walls

Abstract:

This research explores and examines the factors that influence customers’ attitude and intention towards switching in the energy (gas and electricity) markets in Western Australia (WA). It integrates push–pull theory (PPT) and the theory of planned behaviour (TPB) to understand what influences potential customers’ intention to switch electricity suppliers if the WA market were to be deregulated. A two-phase, mixed methods, sequential exploratory approach was adopted. In the first phase, a qualitative study was conducted through focus group sessions using semi-structured interview questions. Five focus group sessions were conducted face-to-face. The data collected through focus group sessions were analysed through thematic analysis. Four major categories of factors were identified: (1) good experiences, which may make customers stay with their current service provider; (2) poor experiences, which may cause customers to switch from their current service providers; (3) factors causing switching (e.g., better options offered by a competitor); and (4) factors that prevent people from switching (e.g., switching costs and consumer inertia). These themes were combined with those themes from the literature review to develop a conceptual framework as a basis for model testing in the quantitative phase of the research. A self-administered survey instrument was administered, and 405 responses were collected from a Qualtrics panel of WA gas and electricity consumers. The data were tested with partial least squares structural equation modelling. The analysis found that the push and pull factors in the energy markets have positive (except for perceived relative price) and significant effects on attitude towards switching, and on switching intention through attitude towards switching. However, the direct effect of push and pull factors on switching intention was not strong and included non-significant relationships of positive past switching experience and negative customer-based reputation of a service provider on switching intention. The strongest impact on switching intention was from attitude towards switching, which was a mediator. Stronger effects of subjective norms on attitude towards switching were found, while its effect on switching intention was not much stronger, even though it was significant. Finally, the impact of perceived behavioural control on switching intention was not supported by the results. Overall, the study contributes to existing body of knowledge by revealing a more nuanced picture of relationships that exist between push (perceived relative price, positive past switching experience, negative customer-based reputation of a service provider) and pull (positive electronic word-of-mouth, positive customer-based reputation of a service provider) factors. It also offers implications for managers, energy retailers and regulators in terms of serving customers better if the WA electricity market were to be deregulated in the future. However, this research has limitations. For instance, as the population for this study consisted of gas and electricity consumers in Western Australia, generalisability of this research is limited. Nevertheless, the research also offers directions for future research. As the research is conducted in a specific geographical context, the framework of this research can be used in other geographical settings to test the relevance and effectiveness of the model. In addition, since the current framework focuses on “mediation”, future research should investigate the impact of “moderators”, which might increase the predictive power of the model.

Abstract:

A helpful tool in forming, breaking, and maintaining habits and behaviors is a digital behavior change intervention (DBCI). These are interventions that leverage digital technologies to help their users to either take on or avoid certain behaviors. A common problem is a lack of user engagement with the interventions’ content, which is key for its effectiveness. It has however been shown that gamified content and using prompts—such as push notifications—may have the effect of increasing user engagement, for both DBCIs and other applications. Furthermore, two commonly occurring game concepts are competition and cooperation, each with different influences on engagement which in turn may vary depending on the context and the user. Therefore, this thesis set out to examine how push notifications can be used to increase user engagement with a gamified DBCI by making its gamified elements more salient. Additionally, it will investigate if there is any difference in influence on engagement of notifications that either promote competition or cooperation. This was evaluated by deploying two different push notification strategies on Deedster—a gamified mobile DBCI with the aim to get its users to reduce their personal CO2-emissions—and tracking user behavior. The results of the evaluation showed that users who received push notifications were more engaged—started more sessions and spent more time—with the application than users who did not receive any. They also performed a significantly higher amount of target behaviors. There was no difference in the influence on performed target behaviors between the notifications promoting competition or cooperation, and only one significant difference—usage of intervention features—regarding user engagement. The gender of the user was also found to be a considerable factor in the influence of the push notifications. Competition increased engagement more than cooperation for male users, but not for female users.
Ett effektivt verktyg för att forma, bryta eller bibehålla vanor och beteenden är en så kallad digital beteendeförändrings-intervention (eng. digital behavior change intervention eller DBCI). Dessa interventioner använder digital teknik för att hjälpa deras användare att antingen påbörja eller undvika särskilda beteenden. Ett vanligt problem med dessa är att användarna ofta inte är särskilt engagerade i interventionernas innehåll eller funktioner, vilket är viktigt för deras effektivitet. Emellertid har det visats att spelifierat innehåll och användandet av notiser—såsom push-notiser—kan ha en ökande effekt på engagemanget. Två vanligt förekommande spelkoncept är tävling och samarbete, båda med sina olika effekter på engagemang vilket också skiftar beroende på kontexten och användaren. Därför ska detta examensarbete undersöka hur push-notiser kan användas för att öka användar-engagemanget i en spelifierad och mobil beteendeförändrings-intervention genom att göra dess spelifierade element mer framträdande. Dessutom kommer det även undersökas om det är någon skillnad i effekt mellan notiser som antingen främjar tävling eller samarbete. Detta var utvärderat genom att använda två olika push-notis-strategier på Deedster—en spelifierad, mobil intervention som syftar till att minska dess användares CO2-utsläpp—och sedan följa användarnas beteende. Resultaten visade att användare som fick push-notiser var mer engagerade—startade mer sessioner och spenderade mer tid—inom applikationen jämfört med användare som inte fick några notiser. De utförde också signifikant fler önskade beteenden. Det var ingen skillnad i effekt på antalet önskade beteende utförda mellan att främja tävling eller samarbete och endast några få skillnader i engagemang. Dock visade det sig att användarens kön var en betydande faktor i effekten av notiserna. Notiserna som främjade tävling var mer effektiva för manliga användare jämfört med de som främjade samarbete. Denna effekt syntes inte bland kvinnliga användare.

Abstract:

During the recession period of 2008/2009, global tourism declined by 8%. This was also evident is South Africa with the domestic travel market shrinking by 8% as well. However, this did not apply to the Kruger National Park (KNP) which experienced a sustained Accommodation Unit Occupancy growth of 1.6% during the same period. Visitors to the KNP thus see it as an attractive holiday destination irrespective of tough economic conditions characterised by less disposable income. To sustain this growth, it is important to be aware of the reasons visitors still visit the KNP during a recession. The aim of this study was to determine the reasons why visitors still travelled to the KNP during the 2008/2009 recession. This can be done by analysing the visitors’ behaviour and the motivational factors (internal feelings of the visitors) and determinants of the demand (income and exchange rates for instance) that influenced visitors’ choice to visit the KNP. To achieve this aim, a survey was conducted at the KNP between 15 and 20 December 2009 (high season). A total of 355 questionnaires were completed, after which a number of analyses were done to determine the effects of the recession on travel behaviour. For the purpose of this study, two articles were written. Article 1 is titled: “Motivations of visitors to the Kruger National Park during the 2008/2009 recession period”. The aim of this article was to determine the motivations of visitors to the KNP during the recession. A factor analysis on the motivations to visit the park was conducted, of which the following factors obtained the highest mean values: Escape, Wildlife experience and Family benefits. Push factors to the KNP were important to such an extent that visitors regarded visiting the park as a primary need or lifestyle. The results furthermore showed that visitors might have adapted their spending behaviour at the park to still afford to visit the park during the recession. This article provides a better understanding of visitors’ feelings towards the KNP, especially amidst recessions which, in turn, will improve niche marketing and a competitive advantage. Article 2 is titled: “Factors that influenced demand to the Kruger National Park during the 2008/2009 economic recession”. The aim of this article was to identify the determinants that influence the demand for visits to the KNP. Due to the homogeneous nature of the park’s market, the results of the stepwise logistic regression analysis revealed a few socio-demographic and behavioural determinants that influenced visitors’ demand to the park. The motives Escape and Souvenirs were the only two behavioural determinants while the provinces Gauteng and Mpumalanga were the only socio-demographic determinants. These two provinces are the two main markets for the KNP. Visitors indicated that visiting the KNP is a great way of escaping their busy metropolitan areas, especially in the Gauteng province. Mpumalanga residents have many tourism attractions in their province thus lowering the chances that they will visit the KNP. The determinant Souvenirs indicates that visitors adapted their spending at the park to still be able to afford visits. It was also found that demand to visit the park was not greatly influenced by the recession, because visitors could adapt their spending at the park. This is the first time the determinants of demand to a national park during a recession period have been conducted. The study indicated that visiting natural areas may have become a primary need or part of a lifestyle, especially during the 2008/2009 recession period. This article gives park management guidelines that will ensure the sustainability of the KNP because this information now allows for well-planned, thorough marketing and management of the park. In the case of KNP, which has a homogeneous market, the number of determinants identified influencing demand for visiting the park is fewer than has been found in other studies done on heterogeneous markets. This study therefore also makes a valuable methodological contribution in relation to analysing demand of homogeneous and heterogeneous markets.

Abstract:

Under de senaste åren har det blivit allt vanligare för konsumenter att använda sig av sociala medier, främst inom turismindustrin. Det är vanligt för konsumenter att idag stöta på nya destinationer och att viljan av att resa uppstår genom sociala medier. Denna studie handlar om att få en djupare förståelse av hur destinationsmarknadsföring tolkas av konsumenter. För att uppnå syfte har dessa två frågeställningar formulerats, Hur möts konsumenterna av destinationsmarknadsföring på sociala medier? och Vilket inflytande påstår konsumenterna att destinationsmarknadsföring inom sociala medier har på deras köpbeslut av destination?. Den empiriska materialinsamlingen har tagits fram genom att genomföra 20 kvalitativa intervjuer på konsumenter. Valet av att genomföra intervjuerna på konsumenter var för att få konsumenternas perspektiv av det valda forskningsområdet. För att analysera den empiriska materialinsamlingen har studien utgått ifrån fem teorier, Social media marketing, Konsumentens beslutsprocess, WOM och eWOM, Personliga egenskapers påverkan på konsumenternas köpbeteende och Push- och Pull faktorer. Studien har kommit fram till att konsumenter ofta möts av destinationsmarknadsföring i sin vardag på sociala medier. Samt att mötet även har ett stort inflytande på konsumenternas köpbeslut, då viljan av att resa uppkommer och beslutet av destination tas.
Over recent years it has become increasingly common for the general populous to use social media, especially for companies and consumers in the tourism industry. This affects the way potential consumers learn about new destinations and also influences their opinions on said places. The aim of this study is to gain a deeper understanding of how destination marketing is interpreted by consumers. In order to achieve this, two questions needed to be answered: How do consumers come across destination marketing on social media? and In what way do consumers feel destination marketing impacts their purchasing decisions? Interviews were conducted with 20 consumers to obtain qualitative data in order to gain an insight on the consumers perspective. Empirical data was analyzed using five different theories: Social Media Marketing, The Buyer Decision Process, WOM and eWOM, Personal Characteristics Affecting Consumers Behavior and Push- and Pull Factors. This study shows that consumers encounter destination marketing on social media often and also that destination marketing has a significant influence on consumers purchasing decisions as it encourages travel and allows selection of destination.

Abstract:

Dans le cadre de la protection du bâti face au risque sismique, les techniques d’analyse simplifiées, basées sur des calculs quasi-statiques en poussée progressive, se sont fortement développées au cours des deux dernières décennies. Le travail de thèse a pour objectif d’optimiser une stratégie d’analyse simplifiée proposée par Chopra et al. (2001) et adoptée par les normes américaines FEMA 273. Il s’agit d’une analyse modale non linéaire découplée, dénommée par les auteurs UMRHA qui se caractérisent principalement par : des calculs de type pushover selon les modes de vibration dominants de la structure, la création de modèles à un degré de liberté non linéaire à partir des courbes de pushover, puis le calcul de la réponse temporelle de la structure en recombinant les réponses temporelles associées à chaque mode de vibration. Dans ce travail, la méthode UMRHA a été améliorée en investiguant les points suivants. Tout d’abord, plusieurs modèles à un degré de liberté non linéaire déduits des courbes de pushover modal sont proposés afin d’enrichir la méthode UMRHA originelle qui emploie un simple modèle élasto-plastique : autres modèles élasto-plastiques avec des courbes enveloppes différentes, le modèle de Takeda prenant en compte un comportement hystérétique propre aux structures sous séismes, et enfin, un modèle simplifié basé sur la dégradation de fréquence en fonction d’un indicateur de dommage. Ce dernier modèle à un degré de liberté privilégie la vision de la chute de fréquence au cours du processus d’endommagement de la structure par rapport à une description réaliste des boucles d’hystérésis. La réponse totale de la structure est obtenue en sommant les contributions non linéaires des modes dominants aux contributions linéaires des modes non dominants. Enfin, la dégradation des déformées modales, due à l’endommagement subi par la structure au cours de la sollicitation sismique, est prise en compte dans la méthode M-UMRHA proposée dans ce travail, en généralisant le concept précédent de dégradation des fréquences modales en fonction d’un indicateur de dommage : la déformée modale devient elle-aussi dépendante d’un indicateur de dommage, le déplacement maximum en tête de l’ouvrage ; l’évolution de la déformée modale en fonction de cet indicateur est directement identifiée à partir des calculs de pushover modal. La pertinence de la nouvelle méthode M-UMRHA est investiguée pour plusieurs types de structures, en adoptant des modélisations éprouvées dans le cadre de la simulation des structures sous séismes : portique en béton armé modélisé par des éléments multifibres pour le béton et les armatures, remplissage en maçonnerie avec des éléments barres diagonales résistant uniquement en compression, bâti existant contreventé (Hôtel de Ville de Grenoble) avec des approches coques multicouches. Les résultats obtenus par la méthode simplifiée proposée sont comparés aux résultats de référence issus de l'analyse temporelle non linéaire dynamique
In the context of building’s protection against seismic risk, simplified analysis techniques, based on quasi-static analysis of pushover, have strongly developed over the past two decades. The thesis aims to optimize a simplified method proposed by Chopra and Goel in 2001 and adopted by American standards FEMA 273. This method is a nonlinear decoupled modal analysis, called by the authors UMRHA (Uncoupled Modal for Response History Analysis) which is mainly characterized by: pushover modal analysis according to the dominant modes of vibration of the structure, setting up nonlinear single degree of freedom systems drawn from modal pushover curves, then determining the history response of the structure by combining of the temporal responses associated with each mode of vibration. The decoupling of nonlinear history responses associated with each mode is the strong assumption of the method UMRHA. In this study, the UMRHA method has been improved by investigating the following points. First of all, several nonlinear single degree of freedom systems drawn from modal pushover curves are proposed to enrich the original UMRHA method, in which a simple elastic-plastic model is used, other elastic-plastic models with different envelope curves, Takeda model taking into account an hysteretic behavior characteristic of structures under earthquakes, and finally, a simplified model based on the frequency degradation as a function of a damage index. The latter nonlinear single degree of freedom model privileges the view of the frequency degradation during the structure damage process relative to a realistic description of hysteresis loops. The total response of the structure is obtained by summing the contributions of the non linear dominant modes to those of linear non dominant modes. Finally, the degradation of the modal shapes due to the structure damage during the seismic loading is taken into account in the new simplified method M-UMRHA (Modified UMRHA) proposed in this study. By generalizing the previous model of frequency degradation as a function of a damage index: the modal shape becomes itself also dependent on a damage index, the maximum displacement at the top of the structure; the evolution of the modal shape as a function of this index is directly obtained from the modal pushover analysis. The pertinence of the new method M-UMRHA is investigated for several types of structures, by adopting tested models of structures simulation under earthquakes: reinforced concrete frame modeled by multifibre elements with uniaxial laws under cyclic loading for concrete and steel, infill masonry wall with diagonal bars elements resistant only in compression, existing building (Grenoble City Hall) with multilayer shell elements and nonlinear biaxial laws based on the concept of smeared and fixed cracks. The obtained results by the proposed simplified method are compared to the reference results derived from the nonlinear response history analysis

Abstract:

ABSTRACT In the practical design applications the evaluation of seismic response is usually based on linear elastic structural behaviour. However this approach may be not sufficient in limiting the damage levels of the buildings. To this purpose more accurate methods of analyses, which can predict the real behaviour under strong seismic actions, are required. The non-linear dynamic analysis is the most rigorous method. The non-linear static pushover analysis seems to be a more rational method for estimating the lateral strength and the distribution of inelastic deformations. In this thesis Pushover analyses were performed by ETABS to predict the behaviour under strong seismic action and comparing the forces in static linear and nonlinear analysis.

The study is to explore the fundamental mechanical behavior on pushover analysis of frame by using the finite element software OpenSees. Taking RC frames as examples subjected to lateral horizontal load, with the definition of plastic hinge as recommended by National Center for Research on Earthquake Engineering. Pushover analysis on OpenSees is proceed by considering the plastic hinge as zero in length of rotational spring and use of concentrated plasticity model. Model validation is by cantilever and 1x1 frame to conduct pushover analysis. Moreover, it is verified by basic mechanical formula and structural analysis and it can be seen as the value of reference with the results of the simulation on mechanical behavior of structural analysis. Finally, conduct the practical discussion on RC framework of beam-column joint of rigid zone through 1x1, 2x1, 2x8 frames and pushover analysis to compare with ETABS software packages. According to the results, it is consistent up to the ultimate point on OpenSees and ETABS; but over the ultimate point, OpenSees stopped and capacity curve from ETABS decreased.

The earthquake resistance design plays an essential role in the design of steel structures. Cyclic behaviour of beam-to-column in crucial in seismic behaviour of moment resisting steel frames. At the moment, the European design code in practice does not provide analytical tools to predict rotational capacity and cyclic performance of selected connection typology, but the code requires design supported by experimental testing or existing data on experimental tests performed on similar connections, what is unfeasible from designer’s point of view. A European project has recently been started with the aim to develop design tool with typical beam-to-column connections used in European practice. In that way, designers will be able to directly use pre-qualified connection without performing experimental tests or literature reviews. One part of this European project is to estimate the seismic demand of the joints in typical D-CBF frames. In order to achieve these objectives seismic performance and dynamic response were estimated on basic of non-linear static analysis and non-linear time history analysis. Numerical models were create in order to perform non-linear static and dynamic analysis using OPENSEES software. Both analysis were performed in accordance with current European design code. The results of non-linear static analysis are presented in form of pushover curve and schematic illustration of formed plastic hinges. Dynamic response was estimated in term of i) maximum floor acceleration, ii) maximum interstorey drift ratio, iii) residual interstorey drift ratio and iv) maximum beam rotation ratio (at the exterior, one-side beam-column joints) at three performance levels: design (D), near collapse (NC) and twice near collapse (2xNC). As main conclusion, the analyses have showed that lateral resistance of D-CBFs is suddenly decrease when brace in compression buckles. This decrease is immediately followed by an increase of lateral stiffness. In seismic demand between selected parameters an important rule have hazard level and height of a structure.

Abstract:

The notion of educating the public through generic healthy eating messages has pervaded dietary health promotion efforts over the years and continues to do so through various media, despite little evidence for any enduring impact upon eating behaviour. There is growing evidence, however, that tailored interventions such as those that could be delivered online can be effective in bringing about healthy dietary behaviour change. The present paper brings together evidence from qualitative and quantitative studies that have considered the public perspective of genomics, nutrigenomics and personalised nutrition, including those conducted as part of the EU-funded Food4Me project. Such studies have consistently indicated that although the public hold positive views about nutrigenomics and personalised nutrition, they have reservations about the service providers’ ability to ensure the secure handling of health data. Technological innovation has driven the concept of personalised nutrition forward and now a further technological leap is required to ensure the privacy of online service delivery systems and to protect data gathered in the process of designing personalised nutrition therapies.

Abstract:

In the war to win the consumer’s attention traditional media is steadily losing ground to new media platforms; which are distributed and consumed digitally, are ubiquitous with the explosive uptake of smart internet connected devices and provide interconnections amongst platforms, devices and even consumers. New media is changing the balance of power in the media landscape from media businesses to media consumers, who now have unlimited choices available to them from which they can decide on what, when, where and how to consume content. So from the traditional outlook of ―mass media‖ there is a transition happening towards ―my media‖ which provide personalised experiences to consumers. The purpose of this study is to contribute to the discussion on how consumer control is changing the media landscape by applying the dichotomy of push vs. pull in media consumption. The study sought to explore if with increasing consumer empowerment, the consumer instead of passively relying on content push from media businesses is now actively pulling content to fulfil his/her individual needs. The study was qualitative and exploratory in nature and utilised in depth and semi structured interviews of media consumers and experts to understand in how the role of the consumer is changing in the media landscape, the factors influencing the change, how the empowered consumer is effecting changes in the way he/she consumes content and media business response to the empowered consumer The study empirically established that consumer control is definitely on the rise in media consumption with consumers preferring to pull content as per their liking. Furthermore it was empirically validated that consumers from lower income levels were as much in control and pulling content as consumers from higher income levels which is a significant departure from the literature. The study also found that even though media businesses acknowledge consumer control in media consumption their response to it is applying certain tactics without any accompanying change in strategies and business models. The study recommended that for media businesses to stay relevant in the age of consumer control and the accompanying content pull; they need to be more customer centric in their approach where they design their strategies and business models by being consumer focussed and trying to fulfil their needs.

Abstract:

Dissertação de mestrado em Structural Analysis of Monuments and Historical Constructions
Earthen constructions constitute a considerable part of the existing heritage and a large percentage of the World population is still living or working in buildings built with this structural system. Like other types of masonry structures, rammed earth constructions are acceptably stable under gravity loads, although they are significantly vulnerable to earthquakes. Therefore, a precise understanding of their behavior in case of being subjected to ground motions and the proposing of effective strengthening techniques achieved a great interest both in research and practice. Strengthening methods should be not only to enhance capacity and ductility of the building, but also to satisfy a variety of criteria such as being compatible with the substrate, economical and reversible. Considering all, the low-cost textile reinforced mortar (LC-TRM) strengthening is introduced, and its efficiency on rammed earth walls is studied numerically in the present thesis. In the current study, the seismic performance of both unstrengthened and strengthened rammed earth structural components is investigated. In this regard, in-plane and out-of-plane behaviors are studied by means of different constructed nonlinear finite element models. At first, pushover analysis by massbased lateral load pattern is conducted on unstrengthened walls to evaluate their capacity and understand possible failure mechanisms. Furthermore, the outcomes of these analyses are employed to select the most proper modeling approach from shell or solid elements and the walls with appropriate geometrical dimensions. In the following, pushover analyses are conducted on strengthened walls to choose between different strengthening materials and assess the effectiveness of the adopted strengthening technique. Furthermore, the frequency change of the walls with the damage states (lateral displacement levels) is studied to represent the initiation and propagation of damage in unstrengthened walls and to evaluate the effectiveness of TRM strengthening method. Finally, an artificially generated ground motion record was applied to both unstrengthened and strengthened walls to perform nonlinear time-history analyses. The outcomes were used to compare the dynamic behavior of the walls against the results of the pushover analyses.
As construções de terra constituem uma parte considerável do património construído e uma grande parte da população mundial ainda vive ou trabalha em edifícios construídos com este sistema estrutural. Como outros tipos de estruturas de alvenaria, as construções de terra são estáveis face a cargas gravíticas, embora sejam significativamente vulneráveis a sismos. Portanto, a compreensão do seu comportamento perante a ocorrência de movimentos do solo e a proposta de técnicas efetivas de reforço despertam um grande interesse, tanto a nível da investigação como na prática. Os métodos de reforço devem ser adequados não só para aumentar a capacidade e a ductilidade da construção, mas também para satisfazer uma variedade de critérios, como a compatibilidade com o substrato, custo económico e reversibilidade. Considerando todos estes aspetos, apresenta-se uma técnica baseada em argamassa reforçada com malhas têxteis de baixo custo (LC-TRM), cuja eficiência em paredes de terra é estudada na presente tese do ponto de vista numérico. No presente trabalho, investiga-se o desempenho sísmico de componentes estruturais de taipa não reforçados e reforçados. A este respeito, estudam-se os comportamentos no plano e fora do plano, por meio de diferentes modelos de elementos finitos não lineares. Em primeiro lugar, realiza-se a análise pushover proporcional à massa em paredes não reforçadas para avaliar sua capacidade e compreender possíveis mecanismos de colapso. Adicionalmente, estes resultados são utilizados para selecionar a técnica de modelação mais apropriada (elementos de casca ou sólidos) e as dimensões geométricas mais apropriadas. De seguida, realiza-se a análise pushover em paredes reforçadas para escolher de entre diferentes materiais de reforço e avaliar a eficácia da técnica de reforço adotada. Além disso, a variação das frequências das paredes com os estados de dano (níveis de deslocamento lateral) é estudada para identificar o início e a propagação de dano em paredes não reforçadas e avaliar a estabilidade do método de reforço baseado na técnica TRM. Finalmente, selecionou-se um registro sísmico artificial para realizar análises temporais não lineares de paredes simples e reforçadas. Os resultados são utilizados para comparar o comportamento dinâmico das paredes com os resultados da análise pushover.

Three frequency triplers based on triple-push ring oscillator were investigated, two of them function as injection-locked just by dual signals in differential. Among the study of injection-locked, the first design by UMC 0.18 μm CMOS process employs an active baluns input. It behaves with locking-range from 44.4 GHz to 46.2 GHz as the injection signal strength being 5 dBm, and the third harmonic output power is -25 dBm, but the harmonic suppression just only 10 dBc lower. When the injection signal strength up to 15 dBm, the locking-range becomes from 44.4 GHz to 47.1 GHz. The third harmonic output power is about -20 dBm, and the harmonic suppression effect is up to 20 dBc. The shortage of this circuit is higher injection strength required and poor harmonic suppression. In order to achieve a higher harmonic suppression, a Wilkinson combining structure was employed in the other two design cases with TSMC 0.18 μm CMOS process, The harmonic suppression could be 25 dBc as the output power being -16.8 dBm at 26GHz without injection locking applied.

The study examines the influences of push and full　factors on international birdwatchers’ travel behaviors. Through snowball sampling and purposive sampling, 257 international birdwatchers were invited to complete an online or a pencil-and-paper self-administered questionnaire, which was designed to assess their reasons for international birding trip (push factors) and the importance of the destination attributes (pull factors). The survey was carried out from March to July, 2013. Results were then analyzed with factor analysis. The results of factor analysis identified four push factor constructs and four pull factor constructs. The importance of push factors are “bird-watching”, “spiritual refresh”, “novelty”, and “achievement”. And the importance of pull factors are “avian resource”, “guide’s professional”, “recreation environment”, and “culture”. With ANOVA analysis, variables such as gender, age, marital status, education level, annual household income, nationality, residency, and level of proficiency, have found distinct impacts on the push and pull factors. The study provides the government, travel operators, and birding clubs, insights in designing international bird-watching tour products.

Full text

Abstract:

Cast-in-place concrete in composite with steel sections is commonly used in bridge deck constructions. The shear transfer between the concrete and steel section is achieved by shear connectors and the strength calculation of conventional shear connectors, i.e. shear studs, is provided in various design codes in North America. Due to the fact that the strength equation is largely based on experimental results, the applicability of the equation is only warranted where the design matches the experimental configuration of the test specimens. Thus, the codes specify detailing requirement for the stud height and the elevation of the reinforcement mesh in relation to the stud height. However, these requirements, in particular, the elevation of the reinforcement mesh, may be difficult to meet accurately in construction practice. The implications of not meeting the mesh requirement to the strength of the shear stud and the remedy solutions are examined in this study. An experimental program involving the test of thirty-three push-out specimens was designed and conducted with a focus on the shear studs' performance. Testing parameters included reinforcement mesh position, shear stud height, presence of stud head, shear stud spacing, and steel flange surface treatment. In addition, the performance of a new type of shear studs, referred to as adjustable studs, was also studied experimentally. The ultimate load and load vs. slip curves were presented and discussed in the forms of tables and graphs. The failure modes were noted and the relationship between the failure modes and the ultimate capacity was discussed. Ultimate loads obtained from specimens were then used to assess the efficacy of code suggested values. Results showed that depending on the elevation of reinforcement mesh, three failure modes were observed including concrete related failure, combined concrete failure and bent studs and stud shear-off from the steel flange. The elevation of the reinforcement mesh had a significant effect on the ultimate load of the specimen. As the mesh elevation increased from intercepting the stud to being in flush with the top of the stud to above the stud, the ultimate load decreased. Specimens with unheaded shear studs had lower ultimate load than specimens with headed shear studs. Flange treatment had an impact on the ultimate load, where the coating on flanges resulted in a decrease in the ultimate load. Test results also showed that the close placement of the shear studs result in a reduction on the ultimate load when the other parameters were kept the same. In the comparison between conventional and adjustable shear studs, specimens with adjustable studs shared similar failure mode to those with conventional studs, but attained on average lower load capacity. The comparison with the code suggested values showed that the code suggested value is only ensured when double-layer reinforcement mesh is used and placed at code specified elevation. A single layer mesh intercepting the studs resulted in the ultimate load slightly lower than the code value. The code values for adjustable studs are markedly higher than the experimental value, which raises the question whether the code equation for conventional studs is directly transferrable to adjustable studs.

This paper presents the experimental and numerical investigation into the behaviour of headed shear studs in composite beams with profiled metal deck flooring. A new single-sided horizontal push test arrangement is proposed to evaluate the shear capacity of the headed shear connectors in pairs with metal deck profiled sheeting. The characteristic resistance obtained from the horizontal push test is compared with Eurocode 4. A three-dimensional finite element model was developed using general purpose finite element program ABAQUS/Explicit. The shear connector capacity, load-slip behaviour and failure modes are validated against experimental results and close correlations were obtained.

Structure failure often occurs in the structure beam-column joint, structure beam, structure column, and structure wall. This failure can adversely affect the comfort level of the structure. Knowing the behavior of structure resulting from the load is important, as it can help to predict the strength of the structure and comfort of the structure being worked on. One way to find out and predict the strength and comfort of the structure as a result of the load received is experimental test and simulation. The simulation VecTor2 used to predict the shear force, crack, and displacement of reinforced concrete beam-column joint, reinforced concrete beam, reinforced concrete column, and reinforced concrete wall when applied the load. This simulation considered the effect of bond stress-slip effect of behavior reinforced concrete. Bonds stress-slip gives a great influence on the strength and hysteretic response of the beam-column joint, column, beam, and wall. That is why this study considers the influence of bond stress-slip on strength beam-column joint, beam, column, and wall. All the result of simulation VecTor2 using bond stress-slip effect would be compared with the result of the experimental test to see the accuracy of the simulation test.

Air pollution is becoming increasingly serious. About 6.5 million people in the world die of air pollution each year, making it the fourth largest cause of death in the world. Air pollution also creates economic losses, which are estimated to be as high as 500 million U.S. dollars. In order to mitigate the harm caused by air pollution, countries have successively formulated emission policies in industry or transportation. For example, Germany and Netherlands will ban fuel vehicles on the road in 2030. Taiwan also announced that it will completely ban the sale of fuel vehicles in 2035. Under the dual factors of environment and policy, this study explored the establishment of a public scooter system and expanded the using range of ubike to reduce the people's willingness to use traditional fuel-powered scooter. Therefore, from the perspective of the traditional scooter users, discuss its willingness to switch public scooter with the PPM theory. The results show that the traditional scooter users' willingness to switch will not only be affected by physical factors such as the environmental attributes of the scooter and the battery life, but also be affected by the recommendation of their relatives and friends and the symbolism of the product.

Full text

Abstract:

This dissertation consists of three independent essays. The first essay, “Long Waves and Short Cycles in a Model of Endogenous Financial Fragility,” presents a stock flow consistent macroeconomic model in which financial fragility in firm and household sectors evolves endogenously through the interaction between real and financial sectors. Changes in firms’ and households’ financial practices produce long waves. The Hopf bifurcation theorem is applied to clarify the conditions for the existence of limit cycles, and simulations illustrate stable limit cycles. The long waves are characterized by periodic economic crises following long expansions. Short cycles, generated by the interaction between effective demand and labor market dynamics, fluctuate around the long waves. The second essay,“Macroeconomic Implications of Financialization,” examines macroeconomic effects of changes in firms’ financial behavior (retention policy, equity financing, debt financing), and household saving and portfolio decisions using models that pay explicit attention to financial stock-flow relations. Unlike the first essay, the second essay focuses on the effects of financial change on steady growth path. The results are insensitive to the precise specification of household saving behavior but depend critically on the labor market assumptions (labor-constrained vs dual) and the specification of the investment function (Harrodian vs stagnationist). The last essay, “Finance, Sectoral Structure and the Big Push,” studies the role of finance in the presence of investment complementarities using a big push model. Due to complementarities between different investment projects, simultaneous industrialization of many sectors (big push) may be needed for an underdeveloped economy to escape from an underdevelopment trap. Such simultaneous industrialization requires costly coordination by a third party, such as the government. Some recent papers show that private banks with significant market power may also solve the problem of coordination failure. We show that private coordination may not work since even large private banks may find it more profitable to finance firms in the traditional sector than in the modern sector.

Along with the development of e-commerce, it has changed consumers’ shopping and purchasing behaviors from the use of the one, traditional channel– physical stores–to multiple channels. Consumer purchasing behaviors have become more complicated. It is difficult to have a single path to describe the consumer shopping behavior. The push-pull-mooring model (PPM) was applied in this study to investigate consumer channel switching behavior related to online channel and offline channel. And whether the use of mobile phones will affect the operation of physical stores. Structural equation modeling was adopted for quantitative analysis and hypotheses testing. The results indicated that push, pull and mooring effects have direct impacts on switching intention. But pull effects and mooring effects have stronger impact on switching intentions than push effects. In addition, the confirmation of mobile phone behavior and the attitude of assisted shopping all have a varying degree of switching behavior. Both the online and offline channels have their own advantages and disadvantages. As consumers’ in-store mobile usage increases, mobile devices can help consumers to combine the benefits of offline and online channel shopping environment. From the managerial perspective, the most important thing is to integrate the multichannel to create a more convenient and quality shopping environment for consumers.

Very often in a manufacturing plant, an important job order must be processed with higher priority than other regular jobs. It will cause the production schedule change as well as the lead- time. This will affect the customer satisfaction and the business income. Therefore, it is vital for management to understand the impact on production performance of these emergent order. This thesis is to make a simulated comparison between MRP （push）and JIT（pull）system while they face emergency orders to understand their transient response towards the unexpected events. The during of the transient response will affect the level of customer service. Three segments can be divided for the response. The first segment(t1) is the response delay time between starting the emergent order and finishing of the first such processing. The second segment(t2)is the processing cycle time for the emergent order.t1 + t2 is the total processing time for the emergent order, i.e. the level of customer satisfaction. The third segment (t3 ) is the time for the system recover to steady state：it is the procedure for the delayed regular order. After the analysis, we found that the “pull” system takes more time than the “push” system in the initial response delay time while they face the emergent order. The total finished time for the emergent order, these two systems are nearly the same. It means that whichever you take does not make quite difference towards the customer service field. The distribution method will affect the duration for the system recover to steady state, the duration of pull system will be shorter while we utilize the exponential distribution of mean arrival rate and the mean service rate. While using normal distribution method the “push” system will be faster.

Mobile payment is a popular issue in global e-commence. It is also a important tool to fulfill the global e-trend and the online business. In the changing of consumer behavior, life behavior is also changed. The goal of this syudy is to understand consumers’ mobile payment behavior by using the Push-Pull-Mooring Model. The effects that influencing adopting behavior towards the mobile payment are discussed. The analysis tool is using survey analysis with PLS-SEM method. Results show that the push factos (quality and trust), effects perceived price positively. Therefore, consumers think the current payment system is better. Mobile payment companies should emphasis the product quality and cyber security to convince consumer switching to mobile payment. The push factors (peer influence and alternative attractiveness) effects previous switching behavior positively. Industries can adopt eWOM via the social network to make consumers know benefits of mobile payment for early adopter. The perceived price effects switching intention negatively. The promotion strategies can attract consumers using the mobile payment. The previous switching behavior effects switching intention positively. Industries need target the earlier adopters first to use the mobile payment.

Abstract:

This paper presents a numerical investigation into the behaviour of headed shear stud in composite beams with profiled metal decking. A three-dimensional finite element model was developed using general purpose finite element program ABAQUS to study the behaviour of through-deck welded shear stud in the composite slabs with trapezoidal deck ribs oriented perpendicular to the beam. Both static and dynamic procedures were investigated using Drucker Prager model and Concrete Damaged Plasticity model respectively. In the dynamic procedure using ABAQUS/Explicit, the push test specimens were loaded slowly to eliminate significant inertia effects to obtain a static solution. The capacity of shear connector, load-slip behaviour and failure modes were predicted and validated against experimental results. The delamination of the profiled decking from concrete slab was captured in the numerical analysis which was observed in the experiments. ABAQUS/Explicit was found to be particularly suitable for modelling post-failure behaviour and the contact interaction between profiled decking and concrete slabs. It is concluded that this model represents the true behaviour of the headed shear stud in composite beams with profiled decking in terms of the shear connection capacity, load-slip behaviour and failure modes.

The development of self-service technologies (SSTs) has significantly changed interactions between customers and enterprises. Similarly, traditional service is gradually being replaced. Self-service laundry, self-service refueling, self-service car washes, self-service tickets, self-checkout shops, and even Q-shops have appeared one after another. Self-service not only has become a new trend but has also resulted in a revolution in traditional consumption patterns and service modes. Why do people continue to use self-service stores? Is it due to the pushing force or the pulling force that they switch from a traditional shop to a self-service store? Or is it due to planned behavior, which is determined by attitude, subjective norms, and perceived behavioral control? This study integrates Ajzen’s (1991) theory of planned behavior and Moon’s (1995) push-pull-mooring theory and discusses which factors influence the continuance intention toward self-service stores. Data were collected from 231 consumers who used self-service car washes and were analyzed using structural equation modeling. Results of this study show that (1) attitude is the most important factor which affects the behavioral intentions for consumers’ continuous use of self-service stores, followed by fun, habit, perceived behavioral control, and personal innovativeness, in order of importance. (2) Subjective norms, low user satisfaction, perceived ease of use, and cost savings do not affect the continuance intention to use self-service stores. Based on the findings, implications for theory and practice are proposed.

Abstract:

Online platforms have emerged during past few years, aiming to disrupt different markets: transportation, housing, rental-housing market are some of the examples. Several factors have contributed to this: a growing digital landscape, geographical proximity and the crisis of 2008. The rental-housing market was also tackled by entrepreneurs, with different platforms rising and changing the way accommodation is searched and advertised. Particularly in Europe, the student rental-housing market, as a submarket of the rental-housing market, has been steadily growing, leading to the appearance of online platforms focused on students search for accommodation. These platforms face, not only the competition of similar ones, but also of indirect competitors – platforms that provide a search for accommodation but that are not focused on students -, and most traditional methods. The modifications on how we look for accommodation made it relevant to understand, for these platforms – given the necessity to retain users and the competitiveness of the market – and their managers, to discern what leads consumers/users to switch a given platform for another. Therefore, using the Push-Pull-Mooring framework to guide our investigation, we aim to assess the impact of different factors in the switching behavior, specifically approaching the demand-side of these online platforms: students. The switching behavior of our target was observed to be potentially influenced by the Push, Pull and Mooring factors tested.
Nos últimos anos emergiram as plataformas online, com o objetivo de serem disruptivas em diversos mercados: na mobilidade, no imobiliário, no arrendamento imobiliário, são apenas alguns dos exemplos. Vários factores contribuíram para tal, o desenvolvimento do mundo digital, a proximidade geográfica e a crise de 2008. O mercado de arrendamento imobiliário não passou incólume à mudança, com diferentes plataformas a surgirem e a alterarem a forma como se procura e anuncia alojamento. Particularmente na Europa, o mercado de arrendamento estudantil, como submercado do mercado de arrendamento, tem crescido constantemente, levando ao aparecimento de plataformas online focadas na procura de alojamento por estudantes. Essas plataformas, enfrentam não apenas a concorrência de outras similares, mas também competidores indirectos – plataformas cujo foco não é a comunidade estudante, mas que também providenciam o mesmo serviço – e métodos mais tradicionais. As alterações na forma como procuramos alojamento, levam a que se torne relevante para essas plataformas – pela necessidade de reter utilizadores e pela altíssima competição existente – e para os seus gestores, perceber que determinantes levam os utilizadores a trocarem determinada plataforma no seu processo de procura de alojamento. Assim, e enquadrados pela teoria Push-Pull-Mooring, o objectivo é analisar o impacto de diferentes factores no comportamento do consumidor, nomeadamente na mudança de plataforma, e especificamente no lado da procura dessas plataformas: os estudantes. O comportamento do consumidor para trocar de plataforma foi observado como potencialmente influenciado pelos factors Push, Pull e Mooring testados.

Abstract:

O objetivo central do nosso estudo é compreender as principais motivações push & pull dos indivíduos seniores, em contexto de viagem para as cidades, e de que forma essa motivação possa contribuir para a construção da “marca cidade”. Sabendo que o envelhecimento da população mundial é uma tendência irreversível na conjuntura mundial, considerando a crescente importância do segmento sénior no turismo, pela disponibilidade financeira e de tempos livres, para a economia dos países, das regiões e das cidades, pretendemos com o presente estudo analisar o papel das motivações dos turistas seniores e os fatores de atratividade das cidades na construção das suas marcas. Depois de revista a principal literatura científica da área, chegamos à conclusão de que, embora haja diversas pesquisas relacionadas com a temática do turismo sénior, foram encontrados pouquíssimos estudos que abordam o tema das motivações dos turistas de cidade, sendo que o destino cidade tem vindo a aumentar significativamente a procura, sobretudo na modalidade de “short city break”, afirmando-se como a motivação de viagens que mais cresceu nos últimos anos. Para compreender melhor as várias nuances da experiência dos turistas seniores e das suas motivações para viajar para cidade, realizamos um inquérito a indivíduos com 55 e mais anos (seniores) e um inquérito a indivíduos com menos de 55 anos e mais de 17 anos (não seniores), possibilitando assim validar algumas hipóteses comparativas das preferências e características de consumo destes dois segmentos demográficos. Com base no trabalho desenvolvido, foi ainda possível caracterizar grupos de seniores com características comuns, quanto às suas motivações e escolha de atributos, relativamente à eleição de um destino turístico cidade.
The central goal of our study is to understand the main push & pull motivations of senior individuals in traveling context. Knowing that the aging of the world population is an irreversible trend in the global environment, considering the importance of the senior segment in tourism, the financial and free time availability, for the economy of the countries, regions and cities, we intend to analyze the role of the motivations of senior tourists and the attractiveness factors of cities building their brands. After reviewing the main scientific literature in this area, we have concluded that although there is some research related to the theme of the senior tourism, few studies address the issue from the point of view of the visit to the city, although the tourism city demand has been increasing significantly, especially in the form of “short city break”, asserting itself as the travel motivation that has increased the most in the last years. In order to understand the several nuances of the experience of senior tourists and their motivations to travel to the city, we have conducted a survey of individuals aged 55 years and over (senior) and a survey of individuals under 55 and over 17 (not senior), thus enabling some comparative validate hypotheses of preferences and consumption characteristics of these two demographic segments. Based on this work it has also been possible to characterize senior groups with common characteristics regarding the election of a tourist destination city as far as their motivations and the attributes of the offer are concerned.
