We carried out a research on thePalicourea rigida(Rubiaceae) inflorescences, a distylous shrub of Brazilian Cerrado. Our objective was to compare the inflorescence architectural complexity and its quality in the two floral morphs and search for any relationship with spider occurrence. In order to assess the quality of inflorescence resources, we quantified the nectar volume and its sugar concentration and the number of fruits and flowers (intact and aborted) for both inflorescence morphs with and without spiders. For the architectural heterogeneity, we quantified floral structures and inflorescence levels of branching. Spider occurrence was higher in longistylous inflorescences than in brevistylous ones. The sampled spiders were classified into the guilds ambushers, jumpers, or orb-weavers. Ambushers, jumpers, and total richness were much higher among longistylous inflorescences. We found no difference between morphs neither in volume or nectar concentration nor in amount of fruits and flowers. However, longistylous inflorescences presented greater architectural heterogeneity than brevistylous ones. Therefore, we suggested that architectural heterogeneity is an important factor underlying the occurrence of cursorial spiders onP. rigidainflorescences, which possibly arose from the relationship between refuge availability and inflorescence architecture.

AbstractWhile scholarship suggests that improving tenure security and housing significantly reduces disaster risk at the household level within urban settings, this assertion has not been adequately tested. Tenure security can be conceived as being composed of three interrelated and overlapping forms: tenure security as determined by legal systems; de facto tenure security; and tenure security as perceived by residents. This article traces the relationship between tenure security, the quality of housing, and disaster risk on the basis of a mixed methods comparative case study of the settlements of Kawangware and Kibera in Nairobi. Although the findings suggest that owner-occupancy is associated with the structural integrity of dwellings to a greater extent than tenantship, no association was found between the length of occupancy by households and the structural integrity of the dwelling. Moreover, tenantship is not found to be closely associated with fires and flooding affecting the dwelling as extant scholarship would suggest. Formal ownership is linked with greater investment and upgrading of property with significant implications for disaster risk. Our findings highlight the complex relationship between tenure security and disaster risk in urban informal settlements and provide impetus for further investigation.

Public governance and income inequality relationship is complex and debatable. This paper examines the extent to which the quality of local governance affects inequality in Vietnam spanning the 2006–2016 period. I apply a generalized method of moments (GMM) estimators to a dynamic panel data extracted from the Vietnam’s provincial competitiveness index and the Vietnam household living standard surveys. The findings are that there is a positive inequality — corruption link but no statistically significant correlation coefficient between the overall level of governance and income disparity. The study, therefore, suggests that the Vietnamese Government at all levels should consider both more effective legal practices and economic low-cost solutions to mitigate corruption.

Purpose – The purpose of this paper is to investigate whether there was a relationship between commitment and the behaviour of organizational citizenship among bank employees. Design/methodology/approach – This paper is based on the outcomes of a doctoral dissertation, which was a case study combining a mix methodology. The results validated the conceptual model proposed by the researcher and answered the research questions. Measurement instruments used include the organizational citizenship scale and the organizational commitment scale, developed and validated by Rosario et al. (2004). Findings – The paper finds that there is a positive correlation between the organizational commitment and the indicators of organizational citizenship behaviour and civic virtue, courtesy and altruism dimensions shown by the employees. The dimensions of affective and moral commitment had the strongest correlation with the civic virtue dimension of organizational citizenship. Research limitations/implications – Sample consist only of private banking employees. Practical implications – The organizations should support the affective and moral commitment in their personnel in order to develop strong citizenship behaviour. Social implications – The organizational commitment with demonstrations of citizenship behaviour, civic virtue, and courtesy and altruism dimensions may impact the organization and the community creating a good base to improve the quality of life. Originality/value – This is the first attempt to study the relationship between organizational commitments and organizational citizenship behaviour in a sample of private banking employees in Puerto Rico.

Abstract China has a civil procedure for collective litigation, which is dubbed Chinese-style class action, as it differs from the U.S.-style class action in some important ways. Using securities class action as a case study, this Article empirically examines both the quantity and quality of reported cases in China. It shows that the number of cases is much lower than expected, but the percentage of recovery is significantly higher than that in the United States. Based on this, the Article casts doubt on the popular belief that China should adopt the U.S.-style class action, and sheds light on the much-debated issue concerning the relationship between public and private enforcement of securities law. The Article also discusses the future prospects of securities class action in China in light of some recent developments which may provide its functional equivalents, including the regulator-brokered compensation fund and public interest group litigation.

Objective: Trust in health care is an important policy area although research has tended to focus on interpersonal trust between patient and practitioner and has neglected trust relations at the organizational and institutional levels. Each of these levels of trust may have been influenced by recent policy and organizational changes in the NHS as well as wider cultural changes. Our aim was to explore the relationship between patients, practitioners and managers to identify if there was any evidence of changes in trust relations. Method: A comparative case study design in two different clinical and organizational settings. Results: Trust is still important for effective therapeutic and working relationships but the nature of that trust and how it is lost and won appears to be affected by the organizational context in which health services are delivered. The increasing partnership between patients and clinicians in managing health problems and the greater interdependence of clinicians and managers in providing multidisciplinary shared care have changed how patients, clinicians and managers trust each other. For many informants trust can no longer be assumed, it is conditional and has to be earned. However, the sources of trust are the quality of the patient- clinician interaction, the competence and empathy that is displayed rather than informed trust based on abstract disembodied data. Likewise in inter-practitioner relationships and clinician-manager relations trust no longer appears to be primarily based on professional status and seniority, instead it appears to be conditional and may be earned through a variety of strategies that demonstrate honesty, reliability, competence, accessibility and an indication that colleagues share similar values and have a common agenda. Conclusion: Trust is still important for effective therapeutic and working relationships.

A residence strongly influences the lifestyle of its occupants and may be a determining factor for the family's quality of life. To maintain the comfort and well-being of its occupants, each dwelling should be adequate for the household. The dwelling should therefore provide a habitable and comfortable environment. Housing space standards in many countries set the conditions for achieving these objectives and generally regulate the overall sizes of individual rooms in addition to the layouts of dwellings. This paper seeks to explore the relationship between habitable area ratios and other component area ratios, such as the structure area, the service area, the circulation area and the open space area, in the context of Iraqi single-family houses. Therefore, this study aims to answer two key questions: Is the habitable area ratio among other ratios compatible with Iraqi housing standards? And does it affect the performance of the units? To this end, the paper adopted a methodology for calculating each area ratio in several newly established complexes in Sulaimaniya City and their relationship to the size of different plot areas for assessing the habitability and efficiency of different house plot areas.

Sacredness in Catholic churches has two aspects: sacredness derived from the purpose and activities of worship and sacredness that arises from the physical and spatial aspects of a church building. The purpose of this study was to reveal factors that affect sacredness in Catholic churches from the perspective of the worshiper. The researchers conducted an exploratory qualitative research to collect text data related to the perception of Catholic church sacredness. The data were collected through an online questionnaire. The researchers also conducted an explanatory quantitative research to uncover the relationship between level of church sacredness and physical and nonphysical factors. The results showed that the ‘sacred spirit’ factor tends to be more dominant in affecting church sacredness compared to ‘sacred object’. Worshipers measure church sacredness according to ‘devoted reflection’, ‘relationship with God’, ‘quality of space’, ‘enclosure acculturation’, and ‘building style’.

Crowdsourcing delivery is becoming a prevalent tool for tackling delivery problems by building a large labor-intensive service network. In this network, the delivery personnel consist of a large number of people with a complex composition and high level of mobility, creating enormous challenges for the quality of service and the management of a crowdsourcing platform. Hence, we attempt to conduct a competence analysis to determine whether they can provide promised services with high quality, i.e., they are competent for their job. To this end, the competence theory is introduced, and a multicriteria competence analysis (MCCA) approach is developed. To illustrate the MCCA approach, a real-world case study is conducted involving a Chinese takeaway delivery platform, where the Bayesian best-worst method is used to determine the weights of the criteria based on the data collected from managers of the platform company. Also, the competence scores of the personnel involved are collected through surveys and data sources of the company. Given the weights and the competence scores, we use additive value function to identify the overall competence scores of them, which reflects the level of competence for their job. The results show that Skills is the most important competence, while Knowledge is the least important of the four competence dimensions. In subcriteria, four core elements are identified such as punctuality, customer service awareness, responsible, and goods intact. In addition to the importance of criteria, a ranking of a sample of personnel is provided, and almost half of the crowdsourcing delivery personnel’s competence is below the average and vary significantly, while the relationship between the competence level and some other variables is also discussed. Moreover, the developed MCCA approach in this paper can be applied to analyze the competence of personnel in many other industries as well.

This chapter presents an archive-based case study of the Bibliotheca Neerlandica, a project launched in 1955 by the newly established Foundation for the Promotion of the Translation of Dutch Literary Works, which aimed to publish commercial English translations of seventeen volumes of Dutch literature, but ended abruptly in 1969 with the publication of the tenth. Through analysis of the underlying aims, the prevailing culture of literary translation, the choices of text and the notion of a ‘Dutch canon’, the structure and management of the commissioning body and the relationship with the publisher, Heinemann, the chapter provides a nuanced cautionary tale about the use of imaginative literature for cultural diplomacy. The chapter documents the breakdown of the project’s relationship with Heinemann, prompted not only by the publisher’s major commercial difficulties in the period, but also by the quality of the translations, which regularly needed review, revision and correction, and the unsuitability of the texts chosen. It highlights the negative reception of those volumes that were reviewed, which found in the texts precisely the claustrophobic provincialism that the series had been conceived to overcome.
