Callaghan, Nicola, James Sommerville, and Nigel Craig. "House builder opinions of energy-efficient homes in the UK." International Journal of Housing Markets and Analysis 7, no. 3 (July 29, 2014): 417–34. http://dx.doi.org/10.1108/ijhma-06-2013-0036.
Full textAbstract:
Purpose – This paper aims to study house builder opinions of energy-efficient homes in the UK. The days of inconsiderate construction methods and disregard for the environment are becoming a thing of the past. If zero carbon (Zc) standards are to be implemented across all new homes within the UK, it is essential that house builders are willing and able to construct such homes to the necessary standards and to the volumes required. Although new generations of low carbon (Lc) and energy-efficient homes are beginning to break into the marketplace, house builders remain reluctant to introduce complex technologies during high effort builds. Design/methodology/approach – The findings from questionnaire responses provide an indication of the views of house builders relating to the incentives encouraging and barriers preventing them from producing mass market energy-efficient homes. Findings – This paper has uncovered the views and opinions of house builders relating to energy-efficient homes. The findings provide evidence that the house building industry is not fully engaged with the energy-efficiency concept; that house builders portray an inconsistent level of confidence in their ability to deliver energy-efficient homes; and that Government targets are too ambitious. Originality/value – The findings within this paper provide an overview of the opinions of house builders relating to energy-efficient homes using statistical analysis.

Full textAbstract:
Fortified boundaries are asymmetrical, physical barriers placed along borders. These boundaries are more formidable in structure than conventional boundary lines, but less robust than militarized boundaries. Their goal is to impose costs on infiltrators and in so doing deter or impede infiltration. A novel dataset of all such boundaries worldwide shows that states are constructing these barriers at an accelerating rate. More than half of barrier builders are Muslim-majority states, and so are the vast majority of targets. A multivariate analysis demonstrates that, contrary to conventional wisdom, states that construct such barriers do not tend to suffer disproportionately from terrorism, nor are they apt to be involved in a significant number of territorial disputes. Instead, differences in state wealth and migration rates are the best predictors of barrier construction. Qualitative case studies suggest that the most effective fortified boundaries are found where the initiating state controls the territory beyond a boundary that blocks the only access route into the state.

Full textAbstract:
The aim of this paper is to propose and demonstrate an approach for exploring diffusion barriers specific to innovative green building products. Innovative green building products aim at reducing environmental impacts during a product's entire life-cycle, helping mitigate the substantial environmental degradation caused by current construction patterns. Few studies establish attributes that differentiate such products within the construction market, a key facet to increasing adoption. For key stakeholders, product attributes can affect the rate of adoption and the nature of use. Toward that end, this work: 1) Collects attributes common to all innovative building products through literature review in residential construction innovation, diffusion and adoption attributes, and green products; 2) utilizes a survey of certified green home builders as a sample population and Structural Insulated Panels as a “control” product to identify which product attributes specifically influence the use of green building products; and 3) Evaluates the relative influence of attributes on product adoption during initial trial of the product and for continued use of the product. Identifying attributes of green building products that influence adoption could enhance product development through reducing barriers to diffusion and commercialization across the residential construction industry. This work focuses on one specific product, Structural Insulated Panel systems (SIPS), from the standpoint of a population of green builders. As such, it attempts to serve as a scalable basis for future research.

Full textAbstract:
Present Tourism Strategy focuses on increasing tourism related employment in Sri Lanka. It is difficult to attract entry level employees to tourism industry given many reasons. This study aims identifying barriers for potential employment for people in rural areas and it will facilitate human resource builders in tourism industry. As a rural area with pool of job seekers, Kotmale was selected for this study. The sample size has been determined by using stratified sampling method and convenience sampling method was used to select respondents. Primary data collected through a pre-tested structured questionnaire and secondary data were used for the study. Mixed methodology was employed to analyze data. The results revealed social considerations, recruitment process, skills development, progression pathways, cultural barriers and lack of infrastructure facilities are significant barriers for tourism employment in rural areas. It is recommended to address the above to make tourism employment attractive for rural job seekers.

Journal of Physical Activity and Health 7, s1 (January 2010): S48—S59. http://dx.doi.org/10.1123/jpah.7.s1.s48.
Full textAbstract:
Background:Although public support for physical activity-friendly Traditional Neighborhood Developments (TNDs) appears to be growing, information is lacking on private sector perspectives and how economic factors (eg, fuel prices) might influence the development and sale of TNDs.Methods:A sample of realtors from the National Association of Realtors (n = 4950) and developers from the National Association of Home Builders (n = 162) were surveyed in early 2009 to assess factors influencing homebuyers' decisions; incentives and barriers to developing TNDs; effects of depressed housing market conditions and financing on sales; trends in buying; and energy considerations (eg, green building).Results:Realtors believed that homebuyers continue to rank affordability, safety and school quality higher than TND amenities. Developers reported numerous barriers to TNDs, including the inability to overcome governmental/political hurdles, lack of cooperation between government agencies, and lack of market demand. Yet, realtors believed clients are increasingly influenced by gas and oil prices, and developers reported that clients are looking for energy efficient homes, reduced commute time, and walkable neighborhoods. Respondents reported consumers are more interested in living in a TND than 5 years ago.Conclusions:Activity-friendly TNDs appear to be increasing in demand, but developers and realtors reported significant barriers to creating these communities.

Full textAbstract:
Reducing energy consumption and environmental impacts of homes remains a critical task for researchers and practitioners. Although numerous energy efficient (EE) home strategies have been developed, their adoption across the entire industry has still been limited. Nationwide, only a small number of EE homes have been built under several well-known EE home programs. Therefore, the research question of, “what prevents EE homes from being widely accepted and built?” needs to be addressed and investigated thoroughly. This paper presents the findings—a comprehensive set of barriers and impediments to the wide spread adoption of EE homes—from an on-going effort made by an alliance of researchers, educators, builders, suppliers, appraisers, real estate agents, and other parties associated with the home construction industry. These findings are being used to develop and implement a holistic action plan to advance the cause of EE homes through research, education, and outreach. The provided insights will also help other researchers, educators, practitioners and government agencies re-evaluate the strategies used in promoting EE homes and improve the effectiveness of on-going and future programs.

"Insights into Public Perceptions of Earthship Buildings as Alternative Homes." Buildings 11, no. 9 (August 25, 2021): 377. http://dx.doi.org/10.3390/buildings11090377.
Full textAbstract:
Sustainable futures necessitate a concomitant requirement for both sustainable buildings and sustainable behaviours under one roof. The defining principles behind Earthship buildings are to promote the use of local, recycled, waste, natural and renewable materials in their construction, for the adoption of a passive solar design for internal heating/cooling, collection of rainwater as a potable water supply, and encourage the onsite recycling of used water for plants to aid food production. However, despite growth in Earthship buildings constructed across many countries of the world, their appeal has not yet made a noticeable contribution to mainstream housing. Therefore, this study is the first to attempt to explore public perceptions towards the benefits and barriers of Earthship buildings as a means of understanding their demand by potential home builders/owners. Opinions were sought through questionnaire surveys completed by visitors to the Brighton Earthship building. Results reveal that the public believe that the reclamation of rainwater and greywater, renewable energy consumption and use of recycled materials included in the design/build are the major benefits of Earthship buildings, whilst the opportunity for a modern living style in a conservative lifestyle/setting, having a building that is cheaper than an ordinary home and the possibility of living totally off grid are considered the least beneficial reasons for building Earthship homes. Results also reveal that the public believe acquiring necessary permits/permissions to build may be more complicated, securing financial support (mortgage/loan) may be more challenging, and identifying/attaining suitable building plots are major barriers of Earthship buildings, whilst the futuristic/alternative building design, being built from waste materials and being entirely dependent on renewable resources (rainfall/wind/sunshine) are considered the least important barriers to building Earthship homes. Notwithstanding the participants included in this study already having an interest in Earthship buildings/lifestyles, it is concluded that the general public deem the general principles of Earthships as an acceptable choice of building/living but it is the formal means of building or buying an Earthship home that is the greatest hurdle against the uptake of Earthship buildings. Therefore, if sustainable futures are to be realized, it is proposed that a shift away from traditional house building towards Earthship building will require the involvement of all stakeholders immersed in the building process (architects, planners, builders, investors, lawyers) to path an easier journey for Earthship buildings and sustainable living.

Full textAbstract:
Renovation of apartment houses in the academic literature is identified as one of the most important housing policy areas. This is a complex phenomenon in rapidly aging Lithuanian housing stock conditions. In the scientific literature, the need for modernization of apartment houses is emphasized, but in Lithuania, there is the lack of interdisciplinary studies of this phenomenon. Often, this phenomenon is analyzed in engineering and from an economic point of view, but from a sociological point of view, practically there have been no analyzes. The aim of the article is to reveal the apartment houses renovation policy developments in Lithuania and to highlight the most important problems of renovation.<br />Quantitative research data showed that only a small part of the houses is renovated under the Renovation program. Partial renovation of apartment houses is going on by themselves according to a population initiative. A large proportion of respondents are satisfied with the results, but they listed problems in updating blocks of flats. Without passivity of the population and financial problems, there are other very significant barriers to mass renovation: corruption in government, good construction companies and builders deficiency. Qualitative research results helped to highlight the most important home renovation problems, identify renovation incentives and barriers.

Full textAbstract:
Abstract: New Zealand faces a housing shortage with construction struggling to meet demand. Structurally insulated panels (SIPs) have been demonstrated internationally as a method of construction which could reduce construction time frames, improve the standard insulation in housing, as well as reduce the amount of waste generated on construction sites. However, anecdotal evidence shows that the SIPs’ adoption is lacking, which is, perhaps, attributed to its industry-wide acceptance level. Thus, in this study, the construction stakeholders, such as architects/designers, builders, territorial authorities and homeowners were targeted to shed light on current status of SIPs use, benefits offered and any barriers inhibiting its industry-wide implementation. This was done through a survey, which was designed to understand the construction stakeholders’ experience levels regarding SIPs use in New Zealand as well as their opinions about any problems associated with the SIPs adoption. Although the stakeholders were happy with the thermal performance offered by SIPs, the results indicate that lack of familiarity and understanding are one of the main barriers to the widespread use of SIPs in New Zealand. Moreover, proper training and clear design information are reported to be crucial to make the building and consenting processes efficient, which will ultimately improve the cost-effectiveness. Despite the barriers (to SIPs adoption) documented by stakeholders, the common belief is that SIPs offer wide-range of benefits to improve performance of the built environment; hence, the stakeholders expressed their willingness to design/build/recommend SIP homes. It is hoped that the findings of this study will guide the industry practitioners in investing their efforts in wider adoption of SIPs in New Zealand.

Full textAbstract:
Trust is a decisive feature of social interactions, transactions, and relationships, yet the implications of trust in integration processes has largely escaped sociological inquiry. Based on interviews and focus group discussions with Somali immigrants in Norway, this article examines trust in the context of health care integration. Using empirical examples from a birth-clinic, the MMR-vaccine, and everyday consultancy, the study highlights that the relationship between Somalis and Norwegian health care providers is characterized by a pervasive, mutual unfamiliarity. This unfamiliarity translates to a reliance on selected Norwegian-Somalis who by commanding two health care cultures can engage as bridge-builders to negotiate associated barriers. The article argues that the combination of immigrant background and formal health knowledge constitutes a type of cultural health capital. Although tapping into this capital extends the health care system and enhances Somalis’ ability to invest trust and benefit from entitlements, a shared background is not synonymous with trust.

"Juridical Analysis of Work Agreements at Sea for Seafarers from the Perspective of Affirming People's Welfare: A Study at the Batam Authority and Harbormaster Office." International Journal of Research and Review 8, no. 9 (September 16, 2021): 115–25. http://dx.doi.org/10.52403/ijrr.20210916.
Full textAbstract:
A Sea Work Agreement is a contract between a shipping entrepreneur and a worker in which the latter agrees to do work for pay as a captain or a member of the ship's crew under the entrepreneur's instructions. As a component of a more considerable agreement, a written or spoken labor agreement must satisfy both subjective and objective legal criteria of an agreement. The topic of this study is the legal arrangement of work agreements at sea for seafarers to promote human welfare. A study was conducted by the Batam authorities and harbormaster's office on the implementation and legal analysis of work agreements at sea for seafarers from an affirming people's welfare perspective. Also, the factors that act as impediments or barriers to solutions for work agreements at sea for seafarers from an affirming people's welfare perspective. This research aims to establish the legal structure of work agreements at sea for seafarers to improve their welfare and the execution and legal analysis of work agreements at sea for seafarers to enhance their welfare. Thirdly, determine the elements that lead to the formation of barriers or obstacles, along with some of the aspects that contribute to their resolution. This study aims to gather primary data via field research utilizing a normative approach. The study's findings show that although the legal control of work agreements at sea for seafarers has been chiefly implemented successfully to enhance people's welfare, there are still many barriers in the sector at both an internal and external level. It is anticipated that both ship entrepreneurs and ship personnel will adhere to their agreed-upon and signed maritime labor agreements, making this a legal requirement for builders. Keywords: Sea Work Agreement, Seafarers.

Full textAbstract:
Purpose Mobile apps offer construction workers a quick, affordable and user-friendly platform for meeting their information, communication and computing needs, with nearly 13,000 construction apps currently available in the market. This study aims to report construction managers’ perspectives on the uptake of mobile apps in the New Zealand construction industry. Design/methodology/approach Exploratory research methods were used in two stages. First stage involved interviews with 14 construction managers who were registered with the New Zealand Registered Master Builders Association, followed by an online questionnaire in the second stage. The link of online questionnaire was sent to all members of participating professional organisations by their administrators. In total, 228 responses were received, of which 60 per cent participants completed the entire questionnaire. Findings Results show an overall positive attitude towards the use of apps. Perceptions of top management personnel differed slightly from those of middle managers; the former expressed interest in apps usage at strategic level such as improving long-term client relationship management and satisfaction; while the latter were more interested in the apps use at operational and tactical levels such as task- or project-level productivity improvement. Research limitations/implications Though bias has been minimised by giving equal opportunity to each member of trade and professional organisations to participate in this survey, of the 228 responses received, only 60 per cent participants completed the entire questionnaire. This is below the minimum requirement for a holistic representation of views. As a result, the findings might not be generalised beyond the study’s scope. Originality/value The study provides new insights on the uptake of smartphone apps in New Zealand’s construction sector from the perspective of construction managers who make strategic decisions. The findings have implications for policy formulation and implementation in regards to the use of mobile apps for productivity improvement in the sector. Mobile apps developers could also gain understanding on functional needs and preferences of the construction workforce, which will help in development of more relevant apps.

Philosophical Transactions of the Royal Society B: Biological Sciences 376, no. 1834 (August 4, 2021): 20200182. http://dx.doi.org/10.1098/rstb.2020.0182.
Full textAbstract:
The need for a vast quantity of new buildings to address the increase in population and living standards is opposed to the need for tackling global warming and the decline in biodiversity. To overcome this twofold challenge, there is a need to move towards a more circular economy by widely using a combination of alternative low-carbon construction materials, alternative technologies and practices. Soils or earth were widely used by builders before World War II, as a primary resource to manufacture materials and structures of vernacular architecture. Centuries of empirical practices have led to a variety of techniques to implement earth, known as rammed earth, cob and adobe masonry among others. Earth refers to local soil with a variable composition but at least containing a small percentage of clay that would simply solidify by drying without any baking. This paper discusses why and how earth naturally embeds high-tech properties for sustainable construction. Then the potential of earth to contribute to addressing the global challenge of modern architecture and the need to re-think building practices is also explored. The current obstacles against the development of earthen architecture are examined through a survey of current earth building practitioners in Western Europe. A literature review revealed that, surprisingly, only technical barriers are being addressed by the scientific community; two-thirds of the actual barriers identified by the interviewees are not within the technical field and are almost entirely neglected in the scientific literature, which may explain why earthen architecture is still a niche market despite embodying all the attributes of the best construction material to tackle the current climate and economic crisis. This article is part of the theme issue ‘The role of soils in delivering Nature's Contributions to People’.

Full textAbstract:
Purpose – The users of construction technologies such as builders and trades people have been acknowledged as sources of potentially important innovations. These innovations may be in the form of safer, less labour intensive, or cheaper methods and processes. The purpose of this paper is to assess whether the Australian construction industry is providing an environment where user-based innovation is being supported and implemented. Design/methodology/approach – An explorative study was undertaken to provide an insight into actual experiences of the implementation of user-based innovation. The data were collected through face-to-face semi-structured interviews providing case studies on multiple aspects of the implementation of innovative construction technologies. The cases involved a cross section of advances, including product, tool, and system technologies. Findings – The main motivation behind developing the technologies was problem solving. The associated industries of manufacturing and retail, as well as consultants within the construction industry present the greatest barriers to implementation. Originality/value – This research provides a better understanding of the factors that are preventing the successful implementation of user-based innovative construction technologies in small firms.

Full textAbstract:
Purpose – The purpose of this paper is to examine the implementation of quality management systems (QMSs) of Grade 7 (G-7) Indonesian construction companies. This includes the initial motives that have driven the development of QMSs, barriers to effective QMS implementation, the current practice and integration of QMS-ISO 9001 principles and elements, and the performance of contractors implementing such QMSs. Design/methodology/approach – A survey was conducted involving 403 respondents (Quality Management Representatives, Managers, and Project and Site Engineers) from 77 G-7 as well as ISO 9001 certified Indonesian construction companies. Findings – The main motive for G-7 contractors in establishing and implementing ISO 9001 based QMSs are identified as being to effectively and efficiently control project activities. Respondents apparently do not often experience problems related to QMS implementation. However, issues of management attitude and purpose are identified as barriers that may affect effective QMS implementation. The study highlights the ISO 9001 principles and elements that still require to be more critically applied by G-7 contractors in order to fully implement and improve their current QMS effectiveness. The findings also suggest that, although certified, many G-7 contractors have not yet achieved a satisfactory level of performance to be truly competitive in global markets outside Indonesia. Originality/value – To date, only limited research has been conducted into the application of ISO 9001 in the Indonesian construction industry. The research findings reinforced the value of pursuing more effective QMS implementation. They also support current attempts to introduce ISO 9001 QMSs to a much wider base of Indonesian construction companies, particularly small and medium sized contractors and builders.

AIM: The aim of this research is to examine the importance of community participation in education and social infrastructure in Peri - Urban of Tirana city.MATERIAL AND METHODS: This research states that “involvement of community” is a direct response to giving the community a voice in shaping their future environment to promote urban regeneration in combination with the respecting of the principle of sustainability.RESULTS: This rich picture of community participation and urban planning brings an improver's eye to the real issue on the ground, focused mainly on the guidelines set by the European Union. The goal of the project participation which generates public space, beyond the values that carry on improving the quality of life for the citizens – can illustrate how urban regeneration projects may have a huge impact on the entire city life. The result is to create an area which improves profits and a good lifestyle; re-conceptualization of investment as an investment in urban infrastructure, an investment that can have a large impact even with a relatively low cost.CONCLUSIONS: This article emphasises the need for a real metamorphose to all barriers between builders and users which must be abolished so that building and usage become two different parts, of the same planning process.

Full textAbstract:
Hanging culverts (i.e., outfall elevated above the stream surface) can fragment fish communities in streams by creating upstream movement barriers. We conducted a retrospective study of culvert stream crossings along industrial roads in Alberta’s boreal forest to describe factors relating to the occurrence of hanging culverts and to quantify watershed fragmentation. One-half (50%; 187/374) of culverts surveyed in four watersheds during 2002 and 2003 were hanging. Logistic regression showed that the occurrence of a hanging culvert was positively and significantly related to culvert age and reach slope. We quantified fragmentation in the watersheds as the length-based percentage of stream reaches above hanging culverts. In three watersheds, stream fragmentation was approximately 5%, whereas one watershed showed 20% fragmentation. Extrapolating our results to Alberta’s entire boreal forest, we estimated that several thousand hanging culverts were fragmenting tens of thousands of kilometres of streams in 2003. These numbers are likely increasing as a result of continued road development and ageing culverts. We conclude that the traditional management approach of road builders and regulatory agencies has failed to prevent the development of hanging culverts and fragmentation of small boreal streams in Alberta. We provide recommendations for future study and management of this growing problem.

Full textAbstract:
Purpose – The purpose of this study was to identify factors that motivate or impede faculty use of learning object repositories (LORs). The unified theory of acceptance and use of technology (UTAUT) served as the theoretical framework for this study. Design/methodology/approach – The study used both quantitative and qualitative approaches to explore two research questions relating to factors affecting faculty use of LORs. Research subjects were faculty users in two- or four-year colleges or universities from two LORs: Orange Grove and Wisconsin Online Resource Center (Wisc-Online). Two phases of the study were conducted. Phase I of the study collected data by semi-structured interviews, and data were analyzed by a content analysis method. Based on the results of Phase I, Phase II collected data by a survey instrument, and data were analyzed by descriptive statistics and analysis of variance. Findings – The study identified 22 factors as motivators for faculty use of LORs and 13 factors as barriers for faculty use of LORs. Research limitations/implications – The research policies of Orange Grove and Wisc-Online limited the selection of study participants. Lack of a random sample and a small sample size limited the generalizability of the results and findings of the study. However, as an exploratory research, the results and findings of the study are still valuable for LOR builders and managers to get a better understanding of factors affecting faculty use of LORs, and to develop strategies to recruit more faculty members to use LORs. Practical implications – The findings and results of the study can inform designers and managers of LORs about what positively or negatively influences faculty use of LORs, and serve as a basis to develop strategies to recruit faculty members to use LORs. Originality/value – First, this study identified the factors that motivate or impede faculty use of LORs from actual faculty users’ perspectives, so these factors more accurately reflect LORs’ values to faculty in teaching and course design and the barriers for faculty use of LORs in a practical environment. Second, this study is among the first known to explore these factors using UTAUT as the theoretical framework, and the results of the study also validate UTAUT in the context of faculty use of LORs.

Full textAbstract:
Abstract Objective Given the changing political and social climate around opioids, we examined how clinicians in the outpatient setting made decisions about managing opioid prescriptions for new patients already on long-term opioid therapy. Methods We conducted in-depth interviews with 32 clinicians in Southern California who prescribed opioid medications in the outpatient setting for chronic pain. The study design, interview guides, and coding for this qualitative study were guided by constructivist grounded theory methodology. Results We identified three approaches to assuming a new patient’s opioid prescriptions. Staunch Opposers, mostly clinicians with specialized training in pain medicine, were averse to continuing opioid prescriptions for new patients and often screened outpatients seeking opioids. Cautious and Conflicted Prescribers were wary about prescribing opioids but were willing to refill prescriptions if they perceived the patient as trustworthy and the medication fell within their comfort zone. Clinicians in the first two groups felt resentful about other clinicians “dumping” patients on opioids on them. Rapport Builders, mostly primary care physicians, were the most willing to assume opioid prescriptions and were strategic in their approach to transitioning patients to safer doses. Conclusions Clinicians with the most training in pain management were the least willing to assume responsibility for opioid prescriptions for patients already on long-term opioid therapy. In contrast, primary care clinicians were the most willing to assume this responsibility. However, primary care clinicians face barriers to providing high-quality care for patients with complex pain conditions, such as short visit times and less specialized training.

Full textAbstract:
Purpose The purpose of this paper is to identify, dissect and unravel real-life contextual human capital issues related to George Town’s built heritage from the perspectives of key stakeholders in the heritage arena. Design/methodology/approach The paper opted for an exploratory study using qualitative techniques like in-depth interviews and focus group discussions to gather insights and to listen to the voices from key stakeholders pertaining to issues related to human capital in built heritage. The data were supplemented and complemented by secondary resources such as technical reports, conservation guidelines, by-laws and case studies from other countries. Findings The paper provides empirical insights about real-life issues, barriers and challenges pertaining to human capital in George Town’s built heritage. The key findings from this study revealed that the quantity of professionals and builders is still insufficient and their quality of work has room for improvement. Research limitations/implications Due to the selected research approach, the research results may lack generalisability. Thus, researchers are encouraged to further test the proposed propositions by enlarging the number of respondents or administering this similar study in another locality/historic city (i.e. Malacca ‒ George Town’s twin historic city). Practical implications The paper provides practical implications for the development of the right quantity and quality of human capital for George Town’s built heritage. The findings from this study are also useful for urban managers, policymakers and conservation practitioners. Originality/value This paper fulfils an identified need to examine the real-life issues of human capital in built heritage for George Town.

Full textAbstract:
AbstractIn 1996, George Mitchell became the co-chairman of the All-Party Talks in a polarized Northern Ireland where the extremes had the dominant voice while the center was relatively mute politically. In analyzing Mitchell's actions, we seek to break new ground in the study of mediation. First, we explicitly assess the context to identify key barriers and opportunities. Second, we move beyond general categories of mediator approach – such as communication, formulation, and manipulation – to match classes of mediator action to barriers. Finally,we place these discrete actions in service of a larger purpose by exploring the "mediator as coalition-builder."Whether explicit or implicit, Mitchell's overarching approach in the All-Party Peace Talks can be interpreted as a drive toward creating an outward rippling "coalition of the center against the extremes."Mitchell's effort to forge a coalition of the center led him to follow coordinated and multi-pronged process, issue and timing strategies, which are the main focus of this article. In principle, Mitchell might have sought to forge agreement via very different potential coalitional approaches: for example, seeking to bridge the extremes, seeking consensus among all parties, seeking to forge a dominant coalition on one side or the other that could have prevailed over its opponents, or seeking a sequential divideand-conquer approach to isolate and overwhelm the opposition, etc. Yet for this particular context, the centrist coalitional approach led to significant progress.

Purpose Depending on their institutional context, for new faculty members to successfully manage their transition from doctoral studies to early career, they must show potential as researchers. The purpose of this study was to learn about supports and barriers to researcher development in new faculty members. Design/methodology/approach The investigators solicited open-ended responses from early career faculty members (N = 49) in an online survey. Content analysis was used to provide an initial categorization of supports and barriers identified by the participants. Findings Ten barrier categories (e.g. lack of resources, previous training, lack of mentoring, workload) and eight support categories (e.g. effective research collaborations, supportive university environment, funding) were identified. Research limitations/implications Findings were framed with a social cognitive conceptual model, which parallels previous studies in doctoral research training environments and research productivity and builds on our knowledge of early career faculty development. The study was limited in terms of number of participants and online response format. Practical implications Practical implications to minimize barriers and enhance supports for new faculty researcher development were identified (also drawing from the conceptual model, SCCT). Originality/value Thus, the study has value for university policymakers, administrators, faculty peers, research mentors and assistant professors or doctoral students seeking to develop as researchers.

Full textAbstract:
Purpose This paper aims to extend the theory relating to knowledge sharing barriers and enablers in the public sector information and communication technology (ICT) project context. Design/methodology/approach A case study method was used whereby project managers from each of the seven departments of the Victorian Public Sector in Australia were interviewed about their knowledge sharing practice. A semi-structured interview instrument based on Riege’s (2005) barrier framework was used to explore the barriers to knowledge sharing that they experienced as part of their work. Findings The study found that many of Riege’s (2005) barriers did not apply in the public sector ICT project environment, demonstrating that context matters. In addition, five enablers were identified, resulting in a new model of enablers and barriers to knowledge sharing in public sector ICT projects. Research limitations/implications This study focuses on a single case, the Victorian Public Sector, and consequently the results are not generalisable. Future research should explore the applicability of the model in other public sector ICT project contexts. Practical implications The study highlights the relationship between knowledge sharing and the project manager and the role it plays in project delivery. The model presented provides a starting point for public sector practitioners to develop their knowledge sharing practice, potentially enhancing project outcomes in the process. Originality/value This study examines barriers to knowledge sharing in an under-researched context, that of the public sector ICT project environment. It builds on current theory and provides insights for practitioners in the public sector.

Full textAbstract:
The paper contains a comparative analysis of difficulties in learning foreign languages inside and outside the language environment. On the first stage of the study based on the research of literature the author (1) builds a typology of difficulties in foreign language acquisition inside the language environment; (2) describes the specifics of the adult as a subject of education; (3) gives a definition to the term barrier in foreign language acquisition. A barrier in foreign language acquisition is defined as a students individual reflection of objective and subjective difficulties influencing the learning process, accompanied by frustration, a high level of anxiety and a low learning progress. The second stage of the research deals with comparing students problems inside and outside the language environment. The author interviewed foreign language teachers working inside and outside the language environment about their students learning problems and compared the results. Both stages of the current study proved that the level of barriers inside the language environment is high. Moreover, inside the language environment students demonstrated even more psychological, social, psychophysiological and linguistic barriers than outside. Some types of difficulties exist just inside the language environment: social adjustment difficulties and problems of intercultural communication. However, a few difficulties on the contrary prevail outside the language environment: low auditory ability, low motivation to learn the language, mistrust to teacher as a reliable source of information. The author explains the reasons of a high level of barriers inside the language environment with the tendency to intensify the learning process inside the language environment and a high affective filter due to the necessity to adjust to a new culture and learning conditions. The following conclusion was drawn: on the one hand the language environment stimulates students to learn a language faster, on the other hand it triggers the emergence of additional difficulties in the learning process, especially sociocultural and psychological barriers.

After the Rose Revolution, President Saakashvili tried to move away from the exclusionary nationalism of the past, which had poisoned relations between Georgians and their Armenian and Azerbaijani compatriots. His government instead sought to foster an inclusionary nationalism, wherein belonging was contingent upon speaking the state language and all Georgian speakers, irrespective of origin, were to be equals. This article examines this nation-building project from a top-down and bottom-up lens. I first argue that state officials took rigorous steps to signal that Georgian-speaking minorities were part of the national fabric, but failed to abolish religious and historical barriers to their inclusion. I next utilize a large-scale, matched-guise experiment (n= 792) to explore if adolescent Georgians ostracize Georgian-speaking minorities or embrace them as their peers. I find that the upcoming generation of Georgians harbor attitudes in line with Saakashvili's language-centered nationalism, and that current Georgian nationalism therefore is more inclusionary than previous research, or Georgia's tumultuous past, would lead us to believe.

Full textAbstract:
High passenger and freight transport costs are a barrier to economic growth and social mobility, particularly in Low Income Countries (LICs). This paper considers the current state of knowledge regarding the barriers to achieving lower generalised transport costs. It considers both the road and railway modes across passenger and freight transport. These issues include a reform on the regulations for driver hours (preventing the road infrastructure from overloading), structuring rail concessions, increasing competition, and tackling corruption. Such reforms aim to deliver efficiency gains and service quality improvements at lower costs for users. This paper identifies the knowledge gap in previous research and concludes by setting out a research agenda that builds the evidence base for how the best practices from around the world can best be applied to the specific circumstances in Low Income Countries, with a particular focus on Sub-Saharan Africa and South Asia.

Working environment communication is fundamental to cooperation. In addition to the fact that it builds and looks after connections, work environment communication encourages development. However, the barriers in communication can be a hindrance to information being communicated successfully. This study aims to study the communication issues that are faced by Malaysian employees in the workplace. A questionnaire was developed and distributed to Malaysian workers that comprised of various departments in Malaysia. The questionnaire comprises of questions on the communication problems in the context of the workplace in terms of the language barrier and physical environment. The participants that had contributed to this study were as much as 41 respondents. The respondents involved had assessed the survey based on their personal experiences in their respective organizations. Based on the results of the study, it can be seen on how the language barrier and physical environment of the workplace affect the employees’ conditions. The findings of this study can help employers view these challenges more seriously and consider the possible solutions to the problems that have been discussed. This paper is concluded by providing future researchers recommendations on various communication problems in the workplace to be further investigated and analysed in a more comprehensive manner.

Supply Chain Management: An International Journal 20, no. 2 (March 9, 2015): 179–204. http://dx.doi.org/10.1108/scm-10-2014-0325.
Full textAbstract:
Purpose – This paper aims to present a survey of the perceptions of the barriers to implementing reverse logistics (RL) practices in South Australian (SA) construction organisations. Despite the extensive research on forward logistics and RL, there is a paucity of studies that examine the barriers to implementing RL particularly within the Australian construction industry. This study builds on the ongoing research being undertaken by the authors, entitled “Designing for reverse logistics (DfRL) within the building life cycle: practices, drivers and barriers”, which is examining the best practices and drivers that could be used as a “road map” for developing appropriate solutions for the successful implementation of RL. Design/methodology/approach – Data were collected by utilising a triangulated data collection approach, a literature review and 49 questionnaires. The review of the literature identified 16 barriers to implementing RL. The quantitative survey data were subjected to descriptive and inferential statistics with correlation analysis to examine the relationships between different pairs of variables comprising RL’s critical barriers. Findings – The following barriers were indicated as most significant: lack of incorporation of salvaged materials by designers; regulation restrictions to usage of recovered materials and components; potential legal liabilities; higher costs; and longer-time association with deconstructing buildings. The least ranked barriers were mostly drawn from the operational and industrial categories as being: organisational lack of support for deconstruction due to incompatible design; lack of organisational support for deconstructing buildings due to higher health and safety risks; and inadequate skills and experience for deconstruction (operational). The industrial barrier was related to “higher costs of salvaged materials in comparison to virgin products”. Research limitations/implications – First, the reported findings are focussed on one study that used questionnaire surveys within the construction industry; therefore, the results may not be generalisable to other contexts. Further, studies should be conducted and extended to other industrial sectors beyond the construction industry. Second, the quantitative study (n = 49) used a smaller sample, and the survey items were based on the review of the literature. Practical implications – The identified barriers could be used as a “road map” for the development of appropriate solutions for the successful implementation of RL, and to improve the environment-related decision-making processes of contractors. Originality/value – This study makes a contribution to the body of knowledge on the subject of RL within a previously unexplored SA context. In addition, the study provides some insights on the contributory effects of the barriers to the implementation of RL. It is the first work undertaken to determine the barriers to the adoption of RL within the SA construction industry.

Full textAbstract:
Koh Phi Phi Don is among the most visited island tourism destinations in Thailand. Due to the island’s topography and development patterns, most accommodation suppliers on the island are likely to be exposed to a range of climate change impacts, particularly sea-level rise, which can pose a severe risk to the local tourism operations. This study aimed to explore perceptions of climate change adaptation actions in response to impacts typically associated with climate change. This study, furthermore, investigated possible obstacles, barriers, and incentives influencing decision-making processes of accommodation owner-managers (the private sector) to adapt to climate change. The investigation builds on 81 surveys and 12 in-depth interviews. The findings provide evidence that most of the sampled businesses already implemented (consciously or not) climate change adaptation measures, such as insurance coverage, water treatment appliances, and staff training on emergency responses. Through a concentration of power on the island, their action is hindered, which creates a barrier to a sustainable and climate risk-informed development pathway.

Full textAbstract:
Timber structures in construction have become more popular in recent years. Nevertheless, besides the complexity of designing, contracting and building these structures, a barrier to their market growth is the complexity of their supply chain relationships encompassing architects, engineers, builders and suppliers. The objective of this study is therefore to identify and characterize the supply chain relationships shared by these stakeholders within a massive timber construction project. Twenty-seven semi-structured interviews with architects, structural engineers, builders and timber element suppliers from nine countries, participant observations and secondary data were used to study the various relationship levels involved in timber construction projects. Triangulation and qualitative data analysis were also conducted. Three levels of relationships were then identified: “Contractual,” “Massive timber construction project” and “Massive timber construction industry development.” Results showed that timber structures involve value-added stakeholder relationships rather than linear relationships. These relationships appeared closer and more frequent and involved knowledge and information sharing. Furthermore, prefabricated systems allow for smoother relationships by limiting the number of stakeholders while promoting innovative thinking.

Dr B. R. Ambedkar (1891–1956) is the principal architect of the Indian constitution and one of the most visionary leaders of India. He remains to this day a symbol of humanity. He is the father of Indian Democracy and a nation builder who shaped modern India. But his notion of nationalism and democracy envisioning an egalitarian society has rarely received adequate academic attention. His views on religion, how it affects socio-political behaviour, and what needs to be done to build an egalitarian society are unique. Such reflections in terms of nationalism and freedom of the people are of great significance in contemporary time in India and the world in general. This article attempts to analyse Ambedkar’s vision of nation and democracy. It also seeks to study how caste system is the major barrier to creating a true nation and a harmonious society. What role does religion play in society and politics? Can socio-spiritual values inspire to break down the barriers of caste differences to form an egalitarian society? History bears witness to instances where great minds empowered with deep contemplation on meeting with the suffering of the people (which in itself is both a prerequisite and an inseparable element of social reform and liberation), resulting in radical shifts in perception. Ambedkar is one such genius whose compassionate engagement and deep imagination envisioned the establishment of an ideal society based on non-discrimination and love.

Full textAbstract:
El incremento de los precios de la energía eléctrica, las preocupaciones sobre el cambio climático, la independencia y seguridad energética impulsan el cambio del mercado mundial de la iluminación hacia fuentes de luz energéticamente más eficientes. La iluminación, según estimaciones de la International Energy Agency (IEA), representa casi el 20% del consumo mundial de energía eléctrica. En el Perú, según el Ministerio de Energía y Minas, aproximadamente el 35% de la energía primaria (después de la transformación y/o descontadas las pérdidas) es destinada a la generación eléctrica, la cual presenta consumos importantes en iluminación: Sector Residencial 15% a 30%, sector Comercial aprox. 33%, sector Público aprox. 24% y sector industrial 10% a 15%. Dados estos niveles importantes de consumo en sistemas de iluminación, el uso transversal en todos los sectores, la falta de un marco político regulatorio integral, así como la necesidad de determinar y establecer alternativas de eficiencia energética, es necesario el conocimiento de la situación actual y las perspectivas de los sistemas de iluminación. Para lograr el ahorro de energía en iluminación, la IEA recomienda a los gobiernos: Eliminación progresiva de productos de iluminación ineficientes; adoptar iluminación de calidad, fiabilidad y Estándares Mínimos de Eficiencia Energética (MEPS); apoyar el desarrollo, uso y actualización de las normas internacionales de pruebas y los protocolos de medición para reducir los costos de cumplimiento de la industria y apoyar los requerimientos de política nacional; exigir y promover un mejor diseño y gestión de sistemas de iluminación al asegurar que los códigos de construcción promuevan el uso de la luz natural e incluyan MEPS para sistemas de iluminación, incluya información y formación dirigidas a arquitectos, constructores, propietarios y gestores. Actualmente el mercado está dominado por las tecnologías de iluminación convencionales, las cuales están siendo desplazadas por la tecnología de Iluminación de Estado Sólido (SSL). A nivel mundial, la SSL que comprende LED, OLED y la gestión de los sistemas de iluminación, marcan la tendencia con grandes probabilidades de lograr los objetivos de ahorro y eficiencia energética. La SSL ofrece controlabilidad mejorada, nuevos factores de forma (que facilitan el reemplazo de tecnologías convencionales) y nuevas funcionalidades (base de la industria de la iluminación inteligente) que se pueden integrar con sistemas de sensores y de control, lo que permite mayor ahorro de energía. No obstante, la existencia de tecnologías de mayor eficiencia y características lumínicas, existen barreras para su adopción, principalmente: falta de información y sensibilidad, falta de confianza, mayor costo inicial, incentivos inadecuados, temores percibidos relacionados a la salud y el ambiente. Así mismo, hay una serie de barreras para la adopción de productos SSL, estos comprenden principalmente costos iniciales, confiabilidad, estabilidad de color y compatibilidad; que pueden limitar la adopción. Palabras clave.-Sistema de iluminación, Eficiencia energética, Gestión energética, Lámpara, LED. ABSTRACTRising electricity prices, concerns about climate change, independence and energy security drive the shift from the global lighting market to more energy-efficient light sources. Lighting, according to estimates by the International Energy Agency (IEA), accounts for almost 20% of the world's electricity consumption. In Peru, according to the Ministry of Energy and Mines, approximately 35% of primary energy (after processing and / or discounting losses) is destined to electricity generation, which presents important consumption in lighting: Residential Sector 15 % to 30%, Commercial sector approx. 33%, Public sector approx. 24% and industrial sector 10% to 15%. Given these important levels of consumption in lighting systems, transverse use in all sectors, the lack of a comprehensive regulatory policy framework, as well as the need to determine and establish energy efficiency alternatives, it is necessary to know the current situation and The prospects of lighting systems. o achieve energy savings in lighting, the IEA recommends to governments: Progressive elimination of inefficient lighting products; Adopt quality lighting, reliability and minimum Energy Efficiency Standards (MEPS); Support the development, use and updating of international testing standards and measurement protocols to reduce compliance costs and support national policy requirements; Demand and promote better design and management of lighting systems by ensuring that building codes promote the use of natural light and include MEPS for lighting systems, including information and training for architects, builders, owners and managers. Currently the market is dominated by conventional lighting technologies, which are being displaced by Solid State Lighting (SSL) technology. Worldwide, SSL comprising LED, OLED and the management of lighting systems, mark the trend with great probability to achieve the goals of energy saving and efficiency. The SSL offers improved controllability, new form factors (which facilitate the replacement of conventional technologies) and new functionalities (base of the intelligent lighting industry) that can be integrated with sensor and control systems, allowing greater savings of Energy. However, the existence of more efficient technologies and light characteristics, there are barriers to its adoption, mainly: lack of information and sensitivity, lack of confidence, greater initial cost, inadequate incentives, perceived fears related to health and the environment. Also, there are a number of barriers to adoption of SSL products, these mainly include initial costs, reliability, color stability and compatibility; Which may limit adoption.

Abstract Europe is experiencing a demographic change, resulting in a change in social structure. People are living longer and birth rates are declining. This changing structure in Europe poses special challenges for housing designers and builders. A new approach in the design of real estate must be created and implemented that caters for the future needs of the occupants of the living space in all phases and allows residents to remain self-sufficient in their "home" for as long as possible. In the earliest stages of design, the typical requirements for each phase of life of future, potential residents must already be considered. This is especially true for people with special protection needs, such as those with visual or hearing impairments.

Experimental studies investigating logical reasoning performance show very high errorrates of up to 80% and more. Previous research identified scalar inferences of the sentencesof logical arguments as a major error source. We present new analytical tools to quantify theimpact of scalar inferences on syllogistic reasoning. Our proposal builds on a new classificationof Aristotelian syllogisms and a closely linked classification of reasoning behaviors/strategies.We argue that the variation in error rates across syllogistic reasoning tasks is in part due toindividual variation: reasoners follow different reasoning strategies and these strategies playout differently for syllogisms of different classes.Keywords: syllogisms, reasoning errors, individual variation, scalar inferences.

Full textAbstract:
AbstractHistorically, research on alliance termination assumes that alliance partners only withdraw from alliances in the event of alliance failure (failure-driven alliance termination). However, recent research on the dissolution of alliances shows that firms also withdraw from alliances through alliance partner switch when they find options with higher match quality than the current partner (option-driven alliance termination). This paper builds on previous work in that field and develops a comprehensive conceptual model of drivers of and barriers to partner switch in interfirm alliances. Based on matching theory, the rectification of alliance partner fit is defined in relation to strategic need, social status and social power as the main drivers and switching costs, social embeddedness and social norms as the main barriers to partner switch. Furthermore, it is argued that market uncertainty and behavioural uncertainty as well as the financial strength and social status of the focal firm have a moderating effect on such drivers and barriers.

Abstract. Landfills and waste heaps require an engineered surface cover upon closure. The capping system can vary from a simple soil cover to multiple layers of earth and geosynthetic materials. Conventional design features a compacted soil layer, which suffers from drying out and cracking, as well as root and animal intrusion. Capillary barriers consisting of inclined fine-over-coarse soil layers are investigated as an alternative cover system. Under unsaturated conditions, the textural contrast delays vertical drainage by capillary forces. The moisture that builds up above the contact will flow downdip along the interface of the layers. Theoretical studies of capillary barriers have identified the hydraulic properties of the layers, the inclination angle, the length of the field and the infiltration rate as the fundamental characteristics of the system. However, it is unclear how these findings can lead to design criteria for capillary barriers. To assess the uncertainty involved in such approaches, experiments have been carried out in a 8 m long flume and on large scale test sites (40 m x 15 m). In addition, the ability of a numerical model to represent the relevant flow processes in capillary barriers has been examined.

Objective: Identify facilitators and barriers to implementing standardized outcome measurement in cleft care. Design: Cross-sectional, qualitative study. Setting/Participants: Participants included 24 providers and staff from a large, multidisciplinary cleft team in the southwest United States, 5 caregivers of children with cleft palate (with or without cleft lip) treated by this team, and 3 experts involved in implementing a cleft-specific standardized outcome measurement in the United Kingdom. Interventions: Semistructured, qualitative interviews were conducted exploring perceived facilitators and barriers to implementing standardized outcome measurement in cleft care. Interviews were audio-recorded, transcribed, and analyzed for content. The Consolidated Framework for Implementation Research was used to guide the interviews and analysis. The analysis focused on the characteristics of standardized outcome measurement that directly influence its adoption. Results: Participants identified both facilitators and barriers to implementing standardized outcome measurement. Facilitators included the strength and quality of evidence supporting improvements in cleft care delivery following implementation of standardized outcome measurement and the relative advantage of standardized outcome measurement over continuing the status quo. Barriers included the difficulty adapting standardized outcome measurement to meet local context and patient-specific needs and the complexity of implementing standardized outcome measurement. Conclusions: Providers, staff, and caregivers involved in cleft care perceive multiple benefits from standardized outcome measurement, while also recognizing substantial barriers to its implementation. Results from this study can be used to guide development of an implementation strategy for standardized outcome measurement that builds upon perceived strengths of the intervention and reduces perceived barriers.

Full textAbstract:
The aim of this article is to examine the application of the United Nations Sustainable Development Goals (sdgs) on biological diversity in Nigeria, emphasizing the preconditions for implementation and the barriers and difficulties for their realization. Given Nigeria’s faltering attempts and failure to achieve the biodiversity goals in the Millennium Development Goals (mdgs), a predecessor to the sdgs, this article builds a profile of the salient law and institutional barriers to the implementation and attainment of the sdgs on biodiversity in Nigeria and proffers practical and normative solutions to those challenges. The methodology approach is based in an analytical and survey of the scope and status of the implementation of international law norms on biodiversity in Nigeria. The results indicate that archaic legislative provision on biodiversity; lack of coherent post-2015 biodiversity agenda; lack of institutional coordination; absence of political will; and inadequate stakeholder engagement in evolving national biodiversity plans are the main legal barriers that must be addressed if the sdgs are to be attained in Nigeria.

Full textAbstract:
IntroductionOne-third of Australia’s Aboriginal and Torres Strait Islander population are adolescents. Recent data highlight their health needs are substantial and poorly met by existing services. To design effective models of primary healthcare, we need to understand the enablers and barriers to care for Aboriginal and Torres Strait Islander adolescents, the focus of this study.Methods and analysisThis protocol was codesigned with Apunipima Cape York Health Council that supports the delivery of primary healthcare for 11 communities in Far North Queensland. We framed our study around the WHO global standards for high-quality health services for adolescents, adding an additional standard around culturally safe care. The study is participatory and mixed methods in design and builds on the recommended WHO assessment tools. Formative qualitative research with young people and their communities (exploring concepts in the WHO recommended quantitative surveys) seeks to understand demand-side enablers and barriers to care, as well as preferences for an enhanced response. Supply-side enablers and barriers will be explored through: a retrospective audit of clinic data (to identify current reasons for access and what can be strengthened); an objective assessment of the adolescent friendliness of clinical spaces; anonymous feedback from adolescent clients around quality of care received and what can be improved; and surveys and qualitative interviews with health providers to understand their perspectives and needs to provide enhanced care. This codesigned project has been approved by Apunipima Cape York Health Council and Far North Queensland Human Research Ethics Committee.Dissemination and implicationsThe findings from this project will inform a codesigned accessible and responsive model of primary healthcare for Aboriginal and Torres Strait Islander adolescents.

Full textAbstract:
Purpose Tackling social exclusion, which can lead to social isolation and loneliness, is an important current issue. People with a learning disability have a right to be full members of their communities, yet often experience social exclusion. Community connections play a key role in people developing reciprocal relationships. It is therefore important to know the barriers to full inclusion. The paper aims to discuss this issue. Design/methodology/approach This paper builds on an inclusive research project exploring these issues (Mooney et al., 2019) and aims to place that study’s main findings in a broader academic, policy and practice context. Findings Whilst there is a wide range of literature about social exclusion, lack of friendships and loneliness experienced by people with a learning disability, there is a gap in knowledge regarding some of the specific social barriers that prevent wider social inclusion, and therefore opportunities to make and keep friends. Originality/value This paper relates the findings of an inclusive research project to the current literature. It identifies the social barriers that limit community involvement and draws on the experience of people with a learning disability to find possible ways forward.

The Jacobian matrix represents the relationship of the linear mapping between the space velocity of robot operation and joint space velocity, which is the important link in the process of robot control. According to analyzing the gesture character of the inspection robot when it gets over the obstacles. This paper sets up the dynamitic model of robot by utilizing D-H. Based on that, it builds the Jacobian matrix by adopting differential transformation method, which establishes the foundation of the robots motion planning and real-time control.
