This study was in partnership with the Maine International Trade Center. The Maine International Trade Center was formed to help Maine businesses develop trade internationally and successfully network with international businesses, and connect with governmental and business professionals globally. Maine’s leaders have added resources to the Maine International Trade Center, feeling that it is crucial to Maine’s economic recovery. Maine’s International Trade Center and the Maine Legislature commissioned an extensive research study in 2013. The outcome from this study was the need for further research on global competencies, citizenship and leadership.

The global economies are more connected than any other time in history, consequently so is business. Businesses are competing globally; cost and performance pressures are relentless. Our societies are changing, some having more, and some having less. This study researched the phenomenon of the global citizen leader, and what the cognitive, metacognitive, attitudes and behaviors are for successful executive level business professionals, who are engaged in international trade and global assignments. By studying the dimensions of cultural intelligence, social responsibility, global competence and global civic engagement rich schemas of the complex construct of a global citizen leader came from the experience and stories of thirteen Maine leaders.

The primary goal for this project was to help expand the existing capability of Sikorsky's main rotor blade business from raw material (titanium) through final assembly. The project helped to facilitate the ongoing lean transformation as the factory makes the journey to single-piece flow. During the internship, monthly kaizen events were used to help focus efforts on different areas of the value stream. These activities resulted in changes in the following areas: decrease in cycle times and lead times, reduction in inventory, procedural changes, and a future plan to physically change the factory floor to improve flow.

Main group supramolecular chemistry is a rapidly expanding field that combines the tools of coordination chemistry with the unusual and frequently unexpected coordination preferences exhibited by the main group elements. Application of established supramolecular design principles to those elements provides access to novel structure types and the possibility of new functionality introduced by the rich chemistry of the main group. Chapter I is a general review of the field of main group supramolecular chemistry, focusing in particular on the aspects of coordination chemistry and rational design strategies that have been thus far used to prepare polynuclear "metal"-ligand assemblies. Chapter II is a discussion of work toward supramolecular assemblies based on the coordination preferences of lead(II), in particular focusing on the 2-mercaptoacetamide and arylthiolate functionalities to target four-coordinate and three-coordinate geometries, respectively. Several possible avenues for further pursuing this research are suggested, with designs for ligands that may provide a more fruitful approach to the coordination of lead(II). Chapter III deals with the preparation of As 2 L 3 assemblies based on flexible ligand scaffolds. These assemblies exhibit structural changes in response to temperature and solvent, which may provide some insight into the subtle shape requirements involved in supramolecular guest binding. Chapter IV continues this work with an examination of how ligand structure affects mechanical coupling of stereochemistry between metal centers when the chelate ring is completed by a secondary bonding interaction such as the As-π contact. Finally, Chapter V presents a crystallographic and synthetic study of the nature of the interaction between pnictogens and arene rings. This interaction is ubiquitous in the coordination chemistry performed in the Johnson laboratory; understanding the role these interactions play in determining the final structure of supramolecular assemblies is vital to the preparation of more complex structures. Chapter VI presents a set of conclusions and outlook for future work on lead(II) supramolecular assemblies and the dynamic assemblies prepared from flexible organic scaffolds. This dissertation contains previously published and coauthored material.

Annotation:
High-oxidation state main-group metal complexes are potential alternatives to transition metals for electrophilic C-H functionalization reactions. However, there is little known about how selection of the p-block, main-group metal and ligand impact C-H activation and functionalization thermodynamics and reactivity. Chapter 2 reports density functional theory (DFT) calculations used to determine qualitative and quantitative features of C-H activation and metal-methyl functionalization energy landscapes for reaction between high-oxidation state d10s0 InIII, TlIII, SnIV, and PbIV carboxylate complexes with methane. While the main-group metal influences the C-H activation barrier height in a periodic manner, the carboxylate ligand has a much larger quantitative impact on C-H activation with stabilized carboxylate anions inducing the lowest barriers. For metal-methyl reductive functionalization reactions, the barrier heights, are correlated to bond heterolysis energies as model two-electron reduction energies.In Chapter 3, DFT calculations reveal that arene C-H functionalization by the p-block main-group metal complex TlIII(TFA)3 (TFA = trifluoroacetate) occurs by a C-H activation mechanism akin to transition metal-mediated C-H activation. For benzene, toluene, and xylenes a one-step C-H activation is preferred over electron transfer or proton-coupled electron transfer. The proposed C-H activation mechanism is consistent with calculation and comparison to experiment, of arene thallation rates, regioselectivity, and H/D kinetic isotope effects. For trimethyl and tetramethyl substituted arenes, electron transfer becomes the preferred pathway and thermodynamic and kinetic calculations correctly predict the experimentally reported electron transfer crossover region.In Chapter 4, DFT calculations are used to understand the C-H oxidation reactions of methane and isobutane with SbVF5. SbVF5 is generally assumed to oxidize methane through a methanium-methyl cation mechanism. DFT calculations were used to examine methane oxidation by SbVF5 in the presence of CO leading to the acylium cation, [CH3CO]+. While there is a low barrier for methane protonation by [SbVF6]-[H]+ to give the [SbVF5]-[CH5]+ ion pair, H2 dissociation is a relatively higher energy process, even with CO assistance, and so this protonation pathway is reversible. The C-H activation/[]-bond metathesis mechanism with formation of an SbV-Me intermediate is the lowest energy pathway examined. This pathway leads to [CH3CO]+ by functionalization of the SbV-Me intermediate by CO, and is consistent with no observation of H2. In contrast to methane, due to the much lower carbocation hydride affinity, isobutane significantly favors hydride transfer to give tert-butyl carbocation with concomitant SbV to SbIII reduction. In this mechanism, the resulting highly acidic SbV-H intermediate provides a route to H2 through protonation of isobutane.

Leader-Member Exchange theory analyse work relationships between leader and member. Leader-Member Exchange theory underlines that leader forms distinct quality relationships with each member. The theory is meaningful also because leader and member are treated as both equally important for creation of work relationships. We used in our research Leader-Member Exchange multidimensional model, created by R. C. Liden and J. M. Maslyn (1998), which states that leader-member exchanges are more complex than general leader-member exchange quality index and involves affect, loyalty, contribution and professional respect dimensions. Leader-member exchange quality process is conditioned by communication between leader and member. Also, organizational commitment, work satisfaction and so on of leaders and member are conditioned by Leader-member exchange quality. In our research we made assumption that leader-member exchange quality is mediate variable between feedback of leader and member and organizational commitment and work satisfaction of leader and member. Our research indicates that feedback between leader and member is important indicator of leader-member exchange quality prognosis. Leader-member exchange quality prognosticates not all aspects of organizational commitment and work satisfaction of leader and member, still, according to research results, we can state that leader-member exchange quality is mediate variable between feedback of leader and member and organizational...

Annotation:
Potable water can become contaminated with lead and copper due to the corrosion of pipes, faucets, and fixtures. The US Environmental Protection Agency Lead and Copper Rule (LCR) is intended to target sampling at high-risk sites to help protect public health by minimizing lead and copper levels in drinking water. The LCR is currently under revision with a goal of better crafting sampling protocols to protect public health. This study examined an array of factors that determine the location and timing of "high-risk" in the context of sampling site selection and consumer health risks. This was done using field studies and well-controlled laboratory experiments. A pilot-scale simulated distribution system (SDS) was used to examine the complex relationship between disinfectant type (free chlorine and chloramine), water age (0-10.2 days), and pipe main material (PVC, cement, and iron). Redox gradients developed in the distribution system as controlled by water age and pipe material, which affected the microbiology and chemistry of the water delivered to consumer homes. Free chlorine disinfectant was the most stable in the presence of PVC while chloramine was most stable in the presence of cement. At shorter water ages where disinfectant residuals were present, chlorine tended to cause as much as 4 times more iron corrosion when compared to chloramine. However, the worst localized attack on iron materials occurred at high water age in the system with chloramine. It was hypothesized that this was due to denitrification-a phenomenon relatively unexplored in drinking water distribution systems and documented in this study. Cumulative chemical and biological changes, such as those documented in the study described above, can create "high-risk" hotspots for elevated lead and copper, with associated concerns for consumer exposure and regulatory monitoring. In both laboratory and field studies, trends in lead and copper release were site-specific and ultimately determined by the plumbing material, microbiology and chemistry. In many cases, elevated levels of lead and copper did not co-occur suggesting that, in a revised LCR, these contaminants will have to be sampled separately in order to identify worst case conditions. Temperature was also examined as a potentially important factor in lead and copper corrosion. Several studies have attributed higher incidence of childhood lead poisoning during the summer to increased soil and dust exposure; however, drinking water may also be a significant contributing factor. In large-scale pipe rigs, total and dissolved lead release was 3-5 times higher during the summer compared to the winter. However, in bench scale studies, higher temperature could increase, decrease, or have no effect on lead release dependent on material and water chemistry. Similarly, in a distribution system served by a centralized treatment plant, lead release from pure lead service lines increased with temperature in some homes but had no correlation in other homes. It is possible that changes throughout the distribution system such as disinfectant residual, iron, or other factors can create scales on pipes at individual homes, which determines the temperature dependency of lead release. Consumer exposure to lead can also be adversely influenced by the presence of particulate iron. In the case of Providence, RI, a well-intentioned decrease in the finished water pH from 10.3 to 9.7, resulted in an epidemic of red water complaints due to the corrosion of iron mains and a concomitant increase in water lead levels. Complementary bench scale and field studies demonstrated that higher iron in water is sometimes linked to higher lead in water, due to sorption of lead onto the iron particulates. Finally, one of the most significant emerging challenges associated with evaluating corrosion control and consumer exposure, is the variability in lead and copper during sampling due to semi-random detachment of lead particles to water, which can pose an acute health concern. Well-controlled test rigs were used to characterize the variability in lead and copper release and compared to consumer sampling during the LCR. The variability due to semi-random particulate detachment, is equal to the typical variability observed in LCR sampling, suggesting that this inherent variability is much more important than other common sources including customer error, customer failure to follow sampling instructions or long stagnation times. While instructing consumers to collect samples are low flow rates reduces variability, it will fail to detect elevated lead from many hazardous taps. Moreover, collecting a single sample to characterize health risks from a given tap, are not adequately protective to consumers in homes with lead plumbing, in an era when corrosion control has reduced the presence of soluble lead in water. Future EPA monitoring and public education should be changed to address this concern.

Annotation:
After 30 plus years of research, clergy burnout is an ongoing concern; as such, it is important to identify the causes of this phenomenon. Researchers have already demonstrated that internal factors such as personality types, personal mastery, or conflict management and external factors such as role conflict, excessive activities, or unrealistic expectations, can lead to burnout. The problem that led to this study was that more exploration is needed about clergy's perceptions on leadership and burnout within the church. The purpose of this qualitative phenomenological study was to explore clergy within the Wesleyan Church in the Midwest to discover their perceptions about leadership and burnout within the church. The conceptual framework was shaped by the great man theory of leadership and Maslach's burnout theory. The central research question for this study focused on clergy's perceptions about leadership and burnout within the church. Data were collected using face-to-face semistructured interviews with 23 pastors who are currently leading and experiencing burnout. Data collected included transcribed interviews, field notes, and observations. Data were hand-coded to find key concepts and themes. Two themes that emerged from the data were leadership is understood as hierarchical and leadership is understood as the work of solo actors, which were consistent with the great man theory of leadership. The results of this study may contribute to a better understanding of the factors that lead to clergy burnout. The results of this study will address a gap in literature and may result in positive social change for both the clergy and church congregants because the results can be used to come up with solutions for burnout. This study may also lead to new theories about clergy burnout.

This thesis describes selected reactivity studies of the N-heterocyclic carbene, IPr, towards a range of main group compounds. The synthesis and characterisation of sixty-three compounds, all of which incorporate IPr as a ligand in one of three coordination modes, are detailed herein. The deprotonation of IPr allowed for the isolation of an anionic source of the aIPr: ligand which was synthesised as a novel potassium salt and along with the previously reported lithium salt, was employed in reactions with group 12 and 14 bis(trimethylsilyl)amides and tetrahalides. The further chemistry of such novel products was investigated towards both electrophilic and nucleophilic reagents making use of both the pendant nucleophilic carbene functionality and the electrophilic main group centre. An alternative route to such species was investigated by the spontaneous isomerisation of IPr in the coordination sphere of group 14 tetrabromides and group 15 tribromides. The scope of this reactivity was subsequently investigated and was found to provide a simpler route to access the abnormal coordination mode of IPr. The aIPr ligand which is generated may be deprotonated by additional IPr thereby affording aIPr: ligands. The addition of halide abstracting agents allowed for the synthesis of cationic species stabilised by the coordination of either IPr or aIPr ligands. A unique, spontaneous reductive coupling of two phosphorus centres was discovered to take place upon heating a THF solution of (IPr)PBr3. This allowed for the isolation of a bromide bridged P–P bond with reduced phosphorus centres. This facile reduction chemistry was further explored by reaction with mild reducing agents which provide access to low oxidation state phosphorus compounds in high yields. This chemistry was found to be possible (and more effective) due to the presence of the weaker phosphorus bond to bromine relative to the commonly employed chlorine ligands.

This study was conducted to identify and analyse Mail and Guardian Online moderation outputs which contradicted the platform‟s own stated policy on hate speech and other forms of problematic speech. The moderation outputs considered were a battery of readers‟ comments that were posted in response to Thought Leader blogs on xenophobia published between May and June, 2008. This was the same period a series of xenophobic attacks was taking place in some parts of South Africa, leaving an estimated 62 people dead, more than 30,000 displaced, and countless victims injured and robbed of their property. The attacks were a catalytic moment that enabled a whole range of discursive positions to be articulated, defended, contested and given form in the media. They also made visible the potential tensions between free speech on the one hand, and hate and other problematic speech on the other. Using qualitative methods of thematic content analysis, document review, individual interviews, and an eclectic approach of framing analysis and rhetorical argumentation, this study found instances of divergence between the M&G policy and practice on User Generated Content. It found that some moderator-approved content advocated hate, hatred, hostility, incitement to violence and/or harm, and unfair discrimination against foreign residents, contrary to the M&G policy which is informed by the constitutional provisions in both section 16 of the Bill of Rights and section 10 of the Equality Act. Based on examples in the readers‟ comments of how „the foreigner‟ was made to signify unemployment, poverty, disease, unfair competition, and all manner of deprivation, and bearing in mind how such individuals have also become a site for the violent convergence of different unresolved tensions in the country, the study‟s findings argue that the M&G – a progressive paper dealing with a potentially xenophobic readership (at least a portion of it) – should have implemented its policy on acceptable speech more effectively. The study also argues that the unjustifiable reference to foreigners as makwerekwere, illegals, illegal aliens, parasites, invaders and border jumpers, among other terms, assigned them a diminished place – that of unwanted foreigner – thereby reproducing the order of discourse that utilises nationality as a space for the expurgation of the „other‟. The study argues that the use of bogus (inflated) immigration statistics and repeated reference to the foreigners‟ supposedly parasitic relationship to the country‟s resources also unfairly constructed them as the „threatening other‟ and potentially justified action against them.

Annotation:
Les polymères à empreintes ioniques (IIPs) sont des matériaux poreux hautement réticulés présentant des cavités de reconnaissance spécifiques d'un ion cible, leur permettant ainsi d'avoir une sélectivité élevée. Le travail de thèse présenté se concentre sur la préparation de polymères à empreintes ioniques fluorescents du plomb (Il), c'est-à-dire capables de transformer la reconnaissance de cet ion en un signal de fluorescence, en vue de leur application pour la détection de ce contaminant en milieu marin. Ainsi, dans une première étape, la stratégie adoptée a été de sélectionner un ligand fluorescent original, sélectif du plomb, de l'étudier et de l'utiliser pour l'élaboration des polymères. A partir de ce ligand, un monomère fluorescent de type styrénique a donc été synthétisé (ANQ-ST) dont le signal de fluorescence est exalté lors de l'ajout de plomb (11). La deuxième étape a été consacrée à l'élaboration d'IIPs du plomb (11) à base d'ANQ-ST. Différents paramètres ont été testés: le solvant de polymérisation, la nature de l'agent de réticulation, le diméthacrylate d'éthylène glycol (EGDMA) ou le divinylbenzène (DVB), ainsi que le ratio de monomère fonctionnel (ANQ-ST) par rapport à l'agent de réticulation (2 % et 5 % molaires). Un panel diversifü de techniques de caractérisation a permis d'étudier les propriétés structurales des différents polymères synthétisés ainsi que de valider l'intégration du monomère fonctionnel ANQ-ST dans la matrice polymère. La dernière étape a consisté à évaluer les performances des IIPs pour la détection du plomb (11) par fluorescence Les polymères préparés avec l'EGDMA et 5 % de monomère fonctionnel présentent les meilleurs résultats. Pour ces polymères, l'intensité de fluorescence des IIPs augmente fortement en présence de plomb (11). De plus, la réponse est très peu impactée par l'ajout d'une espèce ionique interférente, contrairement à leurs analogues non-imprimés, soulignant l'efficacité de l'effet d'empreinte. Des droites de calibration ont été établies en milieu aqueux à différents pH et dans différentes matrices, paramètres qui n'ont pas eu d'influence majeure. Les limites de détection obtenues, de 2, 1 et 2,4 µg.L-1, sont inférieures à la recommandation de 1 O µg.L-1 de l'OMS. Ces résultats ont permis de valider avec succès l'utilisation des IIPs fluorescents synthétisés dans le cadre de ce travail de thèse pour la détection du plomb (Il) dans des échantillons naturels en particulier marins
Ion imprinted polymers (IIP) are highly cross-linked porous materials with specific recognition cavities of a target ion. Thus, this kind of materials shows high selectivity. This work focuses on the preparation of fluorescent ion-imprinted polymers specific to lead (11), i.e. capable of transforming the ion recognition into a fluorescence signal, for the detection of this contaminant in marine environment. ln a first step, the strategy adopted was to select and synthesise a fluorescent ligand, specific to lead (11) and t study and use it for the preparation of the polymers. This ligand was modified to produce a styrene type fluorescent monomer (ANQ-ST). An exaltation of the fluorescence signal of ANQ-ST was observed along with lead Il addition. The second ste was dedicated to the develo ment of the lead Il ion-im rinted ol mers. Various parameters were tested: polymerization solvants, nature of crosslinking agent (EGDMA and DVB) and ANQ-ST/crosslinker ratio (2 % and 5% molar). A diversified panel of characterization techniques allowed to study the polymer structures and to evidence the integration of the functional monomer ANQ-ST inside the polymer matrix. The last step consisted in evaluating the performances of the IIPs for the detection of lead (Il) by fluorescence. The polymers prepared with EGDMA and 5 % of functional monomer showed the best results For these polymers, IIPs' fluorescence intensity in the presence of lead (11) was almost not impacted by the addition of interfering ion species, unlike their non-imprinted analogs. These results highlight the effectiveness of the imprinting effect. Calibration curves were established in aqueous media at different pH and in different matrices. Those parameters did not have major influences. The limits of detection obtained are below the World Health Organization recommendation (10 µg.L-1 ). These results were successfully validated by the detection of lead in natural samples, includinçi tests in marine media

Sjökaptensstudenterna på Sjöfartshögskolan i Kalmar har i sin utbildningsplan tolv månaders fartygsförlagd utbildning som är fördelad över tre perioder. Praktiken erbjuder studenterna möjligheten att utöva samt utveckla den teoretiska kunskapen de lärt sig i skolan men även att få uppleva hur det verkligen är att arbeta till sjöss. Arbetsmiljön, den sociala miljön samt hur det är att vara hemifrån under en längre period är saker som studenterna får prova på. Att arbeta till sjöss har många fördelar men även sin utmaningar. Det är ett arbete med hög arbetsbelastning samt höga krav på organisationen ombord, säkerheten och miljömedvetande. Som sjöbefälsstudent på Sjöfartshögskolan i Kalmar hamnar man i denna miljö under sitt första år på utbildningen då man under termin ett åker ut på första praktikperioden. Denna studie syftar till att undersöka hur sjökaptensstudenterna upplever att sömnbrist, kontraktslängd samt arbetstiderna ombord påverkar deras kunskapsinhämtande. För att ta reda på studenternas upplevelser har en kvalitativ intervjustudie genomförts med sex sjökaptensstudenter; endast sistaårsstudenter intervjuades då de genomgått hela eller en stor del av den fartygsförlagda utbildningen och ansågs därför ha mest erfarenhet. Svaren var i de flesta fallen överensstämmande där studenterna upplevde att praktikperioderna samt arbetsdagarna var för långa, att man behövde ha minst en vilodag i veckan och att sömnbrist hade en negativ inverkan på deras kunskapsinhämtande. Samtidigt framkom det i studien vad som vore det mest optimala för sjöbefälstudenternas kunskapsinhämtande, vad gäller optimal längd på praktikperioderna samt optimalt arbetsschema för en så givande och effektiv praktik som möjligt.
The master mariner students at Kalmar Maritime Academy have twelve months of ship-based training which is a part of the education plan, and these twelve months are distributed over three periods. The internship offers the students the opportunity to practice and develop the theoretical knowledge they have gained in school, but also to experience how it really is to work at sea. The work environment, the social environment and what it can be like to be away from home for a longer period are central. Working at sea has many benefits but also its challenges. The job is associated with long periods at sea with a high workload and high demands on the organization on board, as well as safety and environmental awareness. As a master mariner student at Kalmar Maritime Academy, you end up in this environment during your first year of education when you leave school for the first internship period during semester one. This study aims to investigate how master mariner students experience that lack of sleep, contract length and working hours on board affect their knowledge acquisition. To find out the students' experiences, a qualitative interview study was conducted with six master mariner students; only senior year students were interviewed because they had completed all or a large part of the ship-based training and were therefore considered to have the most experience. The answers were in most cases consistent where the students felt that the internship periods and working days were too long, that they needed to have at least one day off a week and that lack of sleep had a negative impact on their knowledge acquisition. At the same time, the study showed what would be the optimal for the master mariner students' knowledge acquisition, in terms of optimal length of internship periods and optimal work schedule for a rewarding and effective internship as possible.

La thèse s’inscrit dans un projet de recherche mené par l’Institut de Recherche Biomédicale des Armées (IRBA). Ce projet vise à répondre à une demande formulée par l’Amiral Commandant des Forces Océaniques et Stratégiques suite à plusieurs incidents dans lesquels un défaut de transmission des informations au sein de l’équipe Sécurité-Plongée des Sous-marins Nucléaires d’Attaque a été identifié comme un facteur causal.Terrain. L’équipe Sécurité-Plongée, située dans le Poste Central Navigation Opérations, est en charge de la conduite et du maintien de la sécurité du sous-marin. Cette équipe travaille en coopération étroite avec d’autres équipes, principalement par l’intermédiaire de la communication verbale (en présentiel et à distance). Une première analyse de l’activité a permis d’identifier le chef d’équipe comme un élément central dans la transmission des informations entre le commandement et les membres de l’équipe Sécurité-Plongée, en charge du contrôle direct du processus. Pour cela, il lui est nécessaire d’élaborer une conscience de la situation adaptée aux objectifs du commandement et aux contraintes auxquelles sont confrontés ses coéquipiers. La recherche de thèse porte sur les mécanismes d’élaboration de la conscience de la situation collective lors de la gestion d’une situation dynamique et à risques.Méthode. Nos observations ont été réalisées auprès de 15 équipes de 6 sous-mariniers, lors de situations de simulation qui s’intègrent dans leur entraînement évalué et préalable à un départ en mission. Ces situations sont fortement contraintes temporellement et sont ponctuées de plusieurs phases de résolution de problèmes. La méthode que nous avons mise en œuvre de façon à étudier l’élaboration de la conscience de la situation collective se base sur la caractérisation des interactions verbales de l’équipe Sécurité-Plongée.Problématique. La thèse défendue est que la conscience de la situation collective émerge à partir des informations partagées au sein de l’équipe. Le chef d’équipe occupant une place centrale dans ce réseau, la caractérisation des informations qu’il échange avec ses coéquipiers permet de rendre compte de la dynamique de l’élaboration de sa conscience de la situation collective.Partie empirique. ─ La première étude de la thèse consiste en l’analyse de l’activité lors d’un épisode intéressant du point de vue de l’élaboration de la conscience de la situation, avec l’alternance de phases de conduite et de résolution de problèmes. Cette étude nous a permis d’identifier la dynamique des tâches réalisées et d’établir deux critères de performance, un pour la conduite et un pour la résolution de problèmes. La seconde étude vise à caractériser les flux de communication en s’appuyant notamment sur une méthode issue de l’analyse des réseaux sociaux. L’objectif est d’étudier d’une part l’impact de l’expérience des opérateurs sur la structure de la communication verbale, et d’autre part les liens entre la structure du réseau et la performance (de conduite et de résolution de problème). La troisième étude vise à identifier les processus cognitifs et les objets mobilisés dans la communication verbale. L’objectif est d’analyser l’impact de l’expérience des opérateurs sur le contenu des communications verbales d’une part, et les liens entre le contenu des communications verbales et la performance d’autre part.L’originalité de la thèse réside en partie dans cette articulation de méthodes d’analyse de la structure et du contenu de la communication verbale, en lien étroit avec l’activité, de façon à comprendre comme s’élabore la conscience de la situation d’un individu central dans un collectif en situation dynamique et à risques
This thesis is part of a research project conducted by the French Institut de Recherche Biomédicale des Armées (Armed Forces Biomedical Research Institute). The project aims to respond to a request made by the Admiral Commander of the Oceanic and Strategic Forces following several incidents in which a failure to transmit information within the SSN’s Diving Safety team was identified as a causal factor.Domain. The Diving Safety team, which is located in the Operation and Navigation Department, is responsible for the driving and maintenance of the submarine’s technical safety. This team works closely with other teams, mainly through verbal communication (face-to-face and remote). An initial analysis of their activities identified the team leader as a key element in the transmission of information between the command post and the members of the Diving Safety team, as this person has direct control of the process. The latter requires developing situation awareness (SA) that meets the objectives set by the command post and the constraints faced by his teammates. The research program described in this thesis focuses on the role of the team leader on mechanisms for developing collective SA when managing a dynamic and risky situation.Method. Our observations were made with 15 teams of 6 submariners, during simulation exercises that are part of their assessed training that is held prior to mission departure. These situations are highly time-constrained and are punctuated by several problem-solving phases. The method that we implemented to study the development of collective SA is based on the characterization of verbal interactions.Problem statement. We argue that collective SA emerges from the information shared within the team. Since the team leader is central in this network, the characterization of the information he exchanges with his teammates makes it possible to report on the dynamics of the development of the collective SA.Empirical studies. The first part of the thesis consists in the analysis of activity during an interesting episode from the point of view of developing SA, with alternating driving and problem-solving phases. This study allowed us to identify the dynamics of the tasks performed, and to establish two performance criteria, one for driving and one for problem solving. The second part aims to characterize communication flows based on a method derived from the social networks analysis. The objective is to study the impact of operators’ experience on the structure of verbal communication, on the one hand, and the links between the network structure and performance (driving and problem solving), on the other. The third part aims to identify in verbal communication the cognitive processes and objects involved in developing collective SA. The objective is to analyse the impact of operators’ experience on the content of verbal communication, on the one hand, and the links between the content of verbal communication and performance on the other.The originality of this thesis lies, in part, in this articulation of methods for analysing the structure and content of verbal communication, in close connection with the activity, in order to understand how collective SA develops in a dynamic and risky situation

Min empiri är insamlad med hjälp av datorstödda mailintervjuer. I och med detta söker jag mönster i respondenternas olika svar utifrån en fenomenografisk ansats. Studiens resultat har gett svar på de frågeställningar som studien utgår ifrån och resultatet visar på en stor variation. Dels finns det variation i respondenternas tolkning av begreppet erfarenhetsbaserad undervisning och det finns även variationer kring deras tolkning av styrdokumenten. Det går också att se olikheter gällande den kompetensutveckling som rektorer organiserar för lärare. På grund av de variationer som råder i samtliga utsagor så kan det bli aktuellt att lyfta vikten av centraliserad tolkning av bärande begrepp på nationell nivå för att komma så nära likvärdig undervisning som möjligt.
The aim of this study is to gain an understanding how the principals choose to develop teacher competence in experience-based teaching. I seek patterns in the different interview answers based on phenomenographic approach. My empirical data was collected with the help of computer-aided mail interviews. The results of the study have given answers to the questions on which the study is based upon and the results show a great variation. Variation in the interpretation of the concept of experience-based teaching and the governance document. But the results also vary regarding the skills development the principals offers teachers. Due to the variations that seem to prevail in all statements, it may be relevant to emphasize the importance of centralized interpretation of key concepts at the national level, in order to get as close to equivalent teaching as possible.

Syfte: Syftet med rapporten var att bättre förstå vilka faktorer som har en inverkan på kapacitetsplaneringen samt de metoder som finns att tillgå gällande kapacitetsplanering. Utefter detta formulerades det tre stycken frågeställningar som studien avser att besvara: Vilka metoder inom kapacitetsplaneringen kan tillämpas i ett kundorderstyrt företag? Vad utmärker kapacitetsplaneringen i ett kundorderstyrt företag? Hur kan kapacitetsplaneringen förbättras utifrån fallföretagets nuvarande situation? Metod: För att besvara frågeställningarna och uppfylla studiens syfte valdes det att genomföras en fallstudie på Lindab Götene AB i Götene. Den första frågeställningen besvaras genom att identifiera relevant teori kring kapacitetsplanering och analysera dessa med empirin. Den andra frågan besvaras med hjälp av empirin där en nulägesanalys har genomförts som ger en inblick i fallföretaget samt den informationen om hur kapacitetsplaneringen tillämpas i fallstudieobjektet. Även här analyseras empirin med teorin. Den tredje frågan besvaras utifrån den analys och insamling av empiriskt material i nulägesbeskrivningen för att identifiera vad som kan förbättras angående kapacitetsplaneringen i en kundorderstyrd verksamhet. Den empiriska datan utgjordes utav intervjuer, dokumentstudier och observationer. Slutsats: I dagsläget sker kapacitetsplaneringen för hela företaget, författarna föreslår att fallföretaget tillämpar metoden kapacitetsbehovsprofiler då den möjliggör att planera kapaciteten per avdelning. Vilket skulle kunna ge en bättre uppfattning om hur beläggningen i produktionen ser ut utifrån fallföretagets förutsättningar. Ytterligare rekommendationer är att utföra tidsstudier för att säkerställa att korrekta operationstider finns tillgängliga som kapacitetsplaneringen baseras på för att inte över- eller underskatta graden av kapacitetsbehov. Uppföljning och återkoppling bör även göras för att se hur produktionen ligger till gentemot planeringen för att även skapa ett underlag för eventuella förbättringar som kan utföras, samt att skapa rutiner och se till att dessa följs.
Purpose: The purpose of the report was to achieve a greater understanding over which factors have an impact on capacity planning as well as the methods available regarding capacity planning. Along this, three questions were formulated that the study intends to answer: Which methods within capacity planning can be applied in a customer-managed company? What distinguishes a capacity planning in a customer-managed company? How can capacity planning be improved in the business case based on the current situation? Method: In order to answer the questions and fulfil the purpose of the study, it was decided to conduct a case study at Lindab Götene AB in Götene. The first question is answered by identifying relevant theory about capacity planning and comparing them with empiric materials. The second question is answered with the help of the empirics where a current situation analysis has been conducted that gives an insight into the case company and the information on how capacity planning is applied in the case study. The theoretical and empirical material are analysed as well. The third question is answered on the basis from the analysis and collection of empirical material in the current situation description to identify what can be improved regarding capacity planning in a customer-ordered business. The empirical data consisted of interviews, documentary studies and observations. Conclusion: Today the capacity plan is created for the whole company as one unit, the authors are suggesting that the business case applies the method capacity bills which makes it possible to plan capacity for each division. Thus, creating a better chance of understanding the current situation in the production. Further recommendations are such as conducting time studies to ensure that correct operational times are available which capacity planning is based on, this for not under- or overestimate the need of capacity. Follow-up and feedback should be done to see how the current situation of the production is against the production plan, also to create a ground for potential improvements that can occur. Creating routines and making sure that they are followed.

Este trabalho apresenta os resultados da monitorização da actividade do polónio (210Po), chumbo (210Pb), potássio (40K) - radionuclidos de origem natural - e do césio (137Cs) - radionuclido de origem artificial -, durante 4 meses (de Janeiro a Abril de 2006), no carapau (Trachurus trachurus), na sardinha (Sardina pilchardus), na pata-roxa (Scyliorhinus canicula), na sarda (Scomber scombrus) e na faneca (Trisopterus luscus). As amostras analisadas compreendem o tecido muscular, o fígado e as gónadas das espécies referidas, capturadas no Atlântico Nordeste, ao largo da zona de Peniche. A concentração do polónio nestas amostras foi sempre mais elevada que a dos outros radionuclidos. Este radionuclido acumula-se preferencialmente nas vísceras e, sobretudo, no fígado. Tendo em conta as taxas de consumo anuais destas espécies, e o seu lugar na dieta, foi calculada a dose de radiação para o consumidor devida à ingestão dos radionuclidos acima referidos. Concluiu-se que a maior contribuição para a dose de radiação é devida ao 210Po, sendo comparativamente muito pequena a contribuição do principal radionuclido de origem artificial, o 137Cs. Não há, pois, no presente um risco de exposição da população Portuguesa às radiações ionizantes pelo consumo dos produtos da pesca.
ABSTRACT: This work shows the results of environmental radioactivity monitoring of polonium (210Po), radioactive lead (210Pb), radioactive potassium (40K) – radionuclides of natural origin – and radioactive cesium (137Cs) – radionuclide of artificial origin. Measurements were made during 4 months (from January till April 2006), on the Atlantic horsemackerel (Trachurus trachurus), the sardine (Sardina pilchardus), the small-spotted catshark (Scyliorhinus canicula), the Atlantic mackerel (Scomber scombrus) and the pouting (Trisopterus luscus). Samples analysed include muscle tissue, liver and gonad of all fish species mentioned above, from captures in the North-East Atlantic off Peniche. 210Po concentration in tissue samples was always higher than concentrations of other radionuclides. Furthermore, 210Po accumulates more in the fish viscera, specially in the liver. Taking into account the annual consumption rates of these species, and its role in Portuguese diet, the radiation dose to consumers through ingestion of those radionuclides was computed. It is concluded that the main contribution for the absorbed radiation dose to consumers is due to 210Po and the radiation dose for 137Cs is comparatively small. At the present, there is no significant ionising radiation exposure risk to the Portuguese population through consumption of fish products.

Par sa finalité et son objet, la formation professionnelle continue appartient au droit de la protection sociale. Elle permet ainsi aux salariés de faire face au risque social d'obsolescence des compétences, mais également de sécuriser leur parcours professionnel. En 1973, le législateur forgea un lien artificiel entre cette matière et le droit du travail en la codifiant au sein du Code du travail. Le droit du travail exerça une influence constante sur la formation professionnelle qui fut orientée en priorité vers les besoins des seuls salariés. La réforme du 5 mars 2014 et les lois qui ont suivi semblent vouloir rompre avec ce cadre juridique artificiel. Le législateur entend consacrer un système d’assurance social, universel, personnel et individuel, ce qui pose la question d'un éventuel droit à la formation et appelle une réforme globale de son mode de fonctionnement
Continuing vocational training in French social law : contributing to the study of a new social insurance.For its purpose and its content, continuing vocational training belongs to the law of social protection. It allows employees to face the social risk of skills' obsolescence but also to secure their professional path. In 1973, the legislator created an artificial link between vocational training and labour law by codifying this field into the Labour Code. Labour Law exercised a constant influence on vocational training which was primarily based on the sole needs of employees. The reform of 5th March 2014 and the subsequent laws seem to have the will to break with this artificial legal framework. The legislator intends to create a system of social insurance which is universal, personal and individual. It raises the question of a potential right to vocational training and calls for a global reform of its functioning

Based on these findings, the work formulates proposals for possible changes to qualification standard issued by the National Qualifications Framework with effect from December 2015, which is the basis for accreditation of the course and its design. The theoretical part of the final work discusses the importance of professionalization in adult education, its impact on the quality of education and the importance of the profession. Nor does it omit the legislative requirements governing further adult education. It also includes a detailed description of the qualification standard of the main leader in the Czech Republic and its comparison with possible foreign concepts, examples of other selected professional qualifications in the field of non-formal and leisure education of children and youth. It also acquaints the reader with the fixed criteria for organizing the recovery events themselves or with the requirements for the personality of the main leader, both formally and informally.

The Master's Thesis focuses on pedagogical and managerial tasks of children camps' main leader. The aim is to define these tasks and to analyse the position's official formal characteristics - professional qualification and experience - for camps organized by bodies that are not leisure time educational centres. The assumption here is that mostly the head chiefs do not hold professional qualification as there is no legal obligation. The Theory uses comparative method to classify camps as leisure time educative activity. Further, the history and legal and practical conditions of the camps are described. Pedagogical and managerial tasks of the head chiefs are explained together with desirable competences. Possible ways of gaining the professional qualification are presented. In the Research part the above stated assumption was supposed to be confirmed or rejected through a questionnaire and additional guided interviews. 103 respondents of the research were head chiefs of children camps organized in 2016 in South Bohemian Region, Czech Republic. Results' analysis rejected the stated assumption. It was proved that a greater-than-expected number of the camps' head chiefs are professionally qualified. At least 50 % of the respondents have the necessary pedagogical qualification together with suitable...

After the economic crises the world is experiencing a huge change which will lead to a new economic model. Now in the transition, our society is trying to design a new model in which the management of the resources will be understood in a different way. The crash in 2007 was the beginning of the change. We need to consider ourselves intellectually very lucky, because now we are able to understand how a new model is being shaped. After reading this thesis you are going to be able to identify some of the changes we as society are experimenting, how are we trying to design this new paradigm and how new companies are trying to manage the resources differently from before. Furthering more, and entering in detail, you will understand the role of shared economies in the freelancing field and its contribution to the fight for unemployment, one of the most harmful macroeconomic indicators in the world right now. A comparison in between the main market leaders in this aspect will allow the reader to know which characteristics contribute to the unemployment fight.

The impact on human health caused by lead release has resulted in stringent lead regulations, which limit the drinking water concentration of lead to 10µg/L. In order to meet regulation guidelines, sources of lead are being removed from the distribution system and premise plumbing. Lead service lines (LSLs) are replaced to minimize the effect of lead release, with LSL contributing as much as 50-75% of total lead at the tap. Adsorption of lead on galvanized iron corrosion scales have been shown to increase lead release in LSL replacements, which is very concerning for utilities considering replacing the LSLs. Adsorption of lead on to iron minerals has been hypothesized as a mechanism for lead exposure. With the significant presence of unlined cast iron pipes in Halifax, the objective of this thesis was to determine the relationship between the iron particles found in cast iron pipes and lead release at the tap.

This study is experimented in the native-tree garden of Huisun Experimental Forest in Guoshing in Nantou County. The weather type of this area is warm heavy-humid type with average temperature 21℃ and average relative humidity 80%. We select ten dominant tree species to measure their leaf photosynthesis and transpiration. Four of them were chosen to probe into the relationships among photosynthetic gas exchange rate and measured meteorological factors. Results were summarized as follows: 1.Formosan Ash had the highest net photosynthetic rate in ten tested species and Ring-cupped Oak was the lowest. Net photosynthetic rates of Laurel family species were higher than those of Beech family species. Leaf conductance and transpiration rate showed the same results. The seasonal variation of the photosynthetic rate for the species of Nanto Actinodaphne and Incense Nanmu were lowest, but that for the species of Formosan Apple, Chinese Cork Oak and Formosan Nato Tree were highest. The seasonal variations of water use efficiency (WUE) for ten tested plants were low. The WUE of Laurel family species were higher than that of Beech family species. 2.In the analysis of the relationships among photosynthetic gas exchange rate, the VPD had negative significant correlation with net photo-synthetic rate and leaf conductance. The VPD had positive significant correlation with transpiration rate. The PPFD and leaf temperature had low correlation with net photosynthetic rate and leaf conductance but positive significant correlation with transpiration rate. 3.In the analysis of the relationships among net photosynthetic rate and stomatal respondence, the net photosynthetic rate increase with leaf conductance and showed positive significant correlation. The leaf conductance had positive significant correlation with non-stomatal factor (Ci/Ca) besides Incense Nanmu. The effect between net photosynthetic rate and stomatal factor was small. 4.The leaf number and net photosynthetic had low correlation among the tested plants except Nanto Actinodaphne. The SPAD and net photo-synthetic also had low correlation among all the tested plants.

A presente dissertação surgiu da necessidade de um esclarecimento no que ao regime jurídico aplicável ao alojamento local concerne, nomeadamente o seu regime fiscal controverso e as consequências jurídicas da sua inserção no ordenamento português. Visa-se, num primeiro momento, esclarecer a origem deste fenómeno de hospedagem. Em segundo lugar, devido à constante comparação entre a tributação dos rendimentos provenientes do alojamento local e os rendimentos provenientes do arrendamento urbano, há uma tendência global que gerou uma sensação de injustiça e desigualdade, criando, assim, a necessidade de um aprofundamento sobre esta temática, urgindo uma concetualização distintiva entre os dois regimes e conceitos. De salientar ainda a problemática da tributação das mais-valias geradas com a afetação e desafetação dos imóveis do património particular para o empresarial e vice-versa. Por último, a par da caraterização do regime fiscal português, as suas caraterísticas, vantagens e lacunas, pretende-se alcançar uma exegese da lei, clara o suficiente para que quem exerce este tipo de atividade o possa fazer em consciência e para que possa perceber quais as opções de tributação mais favoráveis in casu.
The present dissertation arose from the need for clarification regarding the legal regime applicable to local housing, namely its controversial tax regime and the legal consequences of its inclusion in the Portuguese ordering. It is intended, at first, to clarify the origin of this lodging phenomenon. Secondly, due to the constant comparison between the taxation of local housing income and urban lease income, there is a global trend that has created a sense of injustice and inequality, thus creating the need for the need for further study on this subject, urging a distinctive conceptualization between the two regimes and concepts. It should also be pointed out the problem of taxing the capital gains generated by the allocation and disinfection of real estate from private to corporate assets and vice versa. Lastly, along with the characterization of the Portuguese tax system, its characteristics, advantages and shortcomings, it is intended to achieve an exegesis of the law, clear enough that those who practice this type of activity can do so in the most favorable tax options in casu.

Estrela, Paulo Jorge Rodrigues. „Tal como aconteceu noutros domínios jurídicos, o direito de preferência também foi salvaguardado pelo legislador em matéria de arrendamento. É o artigo 1091.º/1-a) do Código Civil português que confere ao arrendatário a faculdade de exercer o direito de preferência em relação ao local arrendado, sempre que o mesmo seja objeto de transmissão onerosa. Assim, sempre que tenha a intenção de proceder à alienação do prédio a um terceiro, o senhorio deverá dar primazia ao arrendatário sempre que este tenha interesse em celebrar o negócio. Tem-se discutido se o arrendatário de parte de prédio não sujeito ao regime da propriedade horizontal terá a oportunidade de exercer o direito de preferência na aquisição da totalidade do prédio, uma vez nunca o poderá fazer em relação à parte que lhe é afeta, pois esta não se encontra juridicamente autonomizada. O direito vigente torna mais difícil o reconhecimento do direito de preferência a estes arrendatários, mas não impossível“. Master's thesis, 2018. http://hdl.handle.net/10316/85804.

O direito de preferência é uma figura jurídica com raízes profundas no ordenamento jurídico português. Tal como aconteceu noutros domínios jurídicos, o direito de preferência também foi salvaguardado pelo legislador em matéria de arrendamento.É o artigo 1091.º/1-a) do Código Civil português que confere ao arrendatário a faculdade de exercer o direito de preferência em relação ao local arrendado, sempre que o mesmo seja objeto de transmissão onerosa.

Preemptive right is a legal figure with deep roots in the Portuguese legal system. Just as it happened in other juridical domains, the preemptive right was also preserved by the legislator in terms of leases.It’s the article 1091.º/1-a) of the Portuguese Civil Code that grants to the lessee the ability to exercise the preemptive right regarding the rented premises, even when it’s the object of an onerous transfer. Therefore, every time that exists the intention to proceed to a transfer of the property to a third party the landlord must give priority to the tenant if he shows interest in doing business. It has been discussed if the lessee of the part of the building not subject to horizontal property will have the opportunity to exercise the preemptive right in the total acquisition of the building, once he will never be able to do it in relation to the part that concerns him, because it’s not legally autonomous. The current law makes it hard to recognize the preemptive right to the tenants although it’s not impossible.-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
