Purpose This study aims to examine the hypothesis that the effect of insurer risks on profitability is conditional on regulation, using two main regulatory directives in the Ghanaian insurance market as a case study. Design/methodology/approach This study used the robust ordinary least square and random effect techniques in a panel data of 30 insurers from 2009 to 2015 to test the research hypothesis. Findings The results suggest that regulations on no credit premium and required capital have insignificant effects on profitability of insurers. On the contrary, this study documents evidence that both policies mitigate the effect of underwriting risk on profitability and suggests that regulations significantly mitigate the negative effect of underwriting risk to improve profitability. Practical implications The finding suggests that policymakers and regulators must continue to initiate, design and model regulations such that they help tame risk to improve the performance of insurers in Ghana. Originality/value This study provides first-time evidence on the role of regulations in controlling risks in a developing insurance market.

And Performance

This article seeks to explain why the World Bank's environmental performance is so uneven despite numerous reform efforts. I argue that a principal-agent model offers a potentially powerful tool for analyzing gaps between the mandates and performance of international organizations (IOs) such as the World Bank. The model is particularly useful when it is calibrated to recognize problems of antinomic delegation and the dual role an IO may have as both agent and principal. Antinomic delegation occurs when states ask IOs to take on complex tasks that are difficult to institutionalize. Recognizing that many IOs may be principal and agent at different stages of the policy process reveals more opportunities for agency slack that are not well addressed by the IO literature. This article presents these modifications to the principal-agent model and applies the model to the case of the World Bank. The case study demonstrates that the nature of the tasks being delegated and the incentives shaping both sides of the principal-agent relationship are key sources of disconnect between the institution's stated goals and its performance.

High Performance Computing architectures have become incredibly complex and exploiting their full potential is becoming more and more challenging. As a consequence, automatic performance tuning (autotuning) of HPC applications is of growing interest and many research groups around the world are currently involved. Autotuning is still a rapidly evolving research field with many different approaches being taken. This special issue features selected papers presented at the Dagstuhl seminar on “Automatic Application Tuning for HPC Architectures” in October 2013, which brought together researchers from the areas of autotuning and performance analysis in order to exchange ideas and steer future collaborations.

This study explores the perceptions of members of 13 competitiveness clusters in Croatia (CCC) towards clusters’ objectives, processes, setting and performance. Survey data (n=250) were analysed using descriptive statistics, exploratory factor analysis and regression analysis. Results indicate that progress of CCCs is not visible in the observed period and they are lagging behind successful cluster initiatives in the world. The most important reasons for underperformance are related to weaknesses inherited in cluster development framework, poor implementation of activities, inadequate resources for pursuing more ambitious objectives, lack of consensus and weaknesses in strategy formulation. The paper contributes to the literature by evaluating the program of competitiveness clusters for the first time. It examines the factors that contribute to performance of clusters, and compares CCCs with best practices of similar associations in the world. Although this research is based on perceptions of members, it has valuable implications for clusters and policy-makers. In order to strengthen existing clusters, changes in the national framework are needed, while clusters should have more resources at their disposal to reach more ambitious objectives in the future.

This study investigated factors related to competency by assessing the mental readiness among highly recognized frontline workers in homelessness services (FWHSs) by means of self-completed questionnaires. A total of 35 highly respected FWHSs in Ottawa, Canada were identified by their peers and supervisors as “exceptional” for various specialty areas: addictions, mental health, hoarding, trauma and post-traumatic stress disorder (PTSD). An Operational Readiness Framework was used to examine how FWHSs perform at their best in challenging situations. A series of questionnaires were completed at a Think Tank to determine their mental readiness before, during and after challenging situations. Quantitative and qualitative analyses of mental readiness were performed to prioritize identified challenges. The study findings were then compared to the “Wheel of Excellence” based on results from elite athletes and other high performers such as surgeons, police, and air traffic controllers. The analysis revealed that mental readiness is required to achieve peak performance in addressing the challenges of homelessness. The balance between readiness (physical, technical and mental) and performance contributed to their competency and resiliency. Common elements of success were found: commitment, self-belief, positive imagery, mental preparation, full focus, distraction control and constructive evaluation. This investigation confirmed many similarities in mental readiness practices engaged by excellent FWHSs and other top professionals. This study offered, for the first time, a comprehensive understanding of specific high-performance readiness practices through a streetwise, frontline-worker perspective. Practical recommendations for training and assessment were provided relevant to excellence in homelessness services.

Maud Allan (1873-1956) was a trailblazer of modern expressionist dance and costume design who drew from her family’s tradition of shoemaking and her experience in corset making to design and construct a novel costume for her renowned and controversial performance, The Vision of Salomé (1906). She wore this costume more than 250 times to perform on the international stage, becoming one of the most successful dancers of her era from 1906 to 1925. By challenging the customs and conventions of Edwardian London through the use of her revealing costume and performance, she was also pioneering costume design, and yet scholarship to date has largely ignored the costume itself as an important material culture object. By using a material culture approach, and performing an object description and analysis of the two sets of Salomé costumes held at Dance Collection Danse in Toronto, this major research project establishes for the first time the many important innovations of Allan’s costume design techniques such as illusion mesh, pearl netting, bejeweled breastplates, eyelet hook bra fasteners and other novel details. Furthermore, I argue that scholarly object analysis used alongside theories of enclothed cognition allows us to elucidate the powerful affective link between psychology and dance costumes, further heightening our appreciation of Allan’s dance costume, while also specifying the details of her problematic appropriation of elements of Orientalism and the Femme Fatale in constructing the costume. More than a century after its creation, the aesthetic of Allan’s costume innovations continues to resonate in other dance costumes today.

Nanotechnology will serve as a suitable solution to achieve high performance in future construction. Using this new technology results in creativity and innovation in the construction industry. One of these new technologies is the smart concrete which has received much emphasis in recent years. Many research and experiments have been conducted in scientific research centers around the world in this regard. It is an undeniable fact that concrete structures are prone to cracking. Natural processes have caused cracks in the concrete through which harmful substances entered the concrete leading to steel corrosion. To tackle this issue through the conventional method of concrete restorative, materials, especially polymers which are also harmful to the environment, are used. An alternative that the scientists have achieved is to employ bacteria in concrete through which to produce self-healing concrete and also to reduce the problems regarding the maintenance of concrete for the environment. Bacteria contribute to the durability and performance of the concrete and increase the service life of the concrete.

AbstractBackground: The world tourism industry is subject to big changes. A number of tourists traveling steadily grows, resulting in turnover and income. The destinations, that tourists are attracted, to are numerous, and there are also newcomers who arrive to a certain destination for the first time. Nowadays, even some very distant places are on the travellers’ bucket lists. What is more, tourists are looking for authenticity, in terms of which the concept of ethno village proves to be such an example.Purpose: The purpose of this paper is to investigate how this kind of tourism is regulated in Slovenia and Bosnia and Herzegovina. The emphasis will be on the study of specific ethno villages.Methods: Regarding the article, desk analysis will be done. The data were gathered from the world web, from the World Tourism Organisation’s data and from the data gathered from Slovenian and Bosnian national statistical office as well. The Excel was used for the analyses. Two examples of an ethno village are also described.Results: The ethno village as a part of rural tourism offers great opportunities for new work posts but capacities should be used to a greater extent and the problem of seasonality should also be overcome. All the key aims of rural development must be defined by the following strategy: the development of sustainable and efficient agricultural sector, the living standard of the population who lives from agriculture, creation of social and economic conditions in the rural regions; all of it within the National strategy of the rural development.Conclusions: Tourism industry is being developing as a part of modern touristic migration. There are more and more visitors coming overseas or coming from more remote places. They stay for a short period of time and they have different expectations as before.
