Possible reasons for using kites to kill gazelles are comprehensively reviewed in this article. Even though they are now well inventoried and documented, desert kites are still not well understood, as exemplified by the recurrent controversies about their function and dating. According to the dominant view, kites were hunting structures used to drive and to mass kill large herds of wild ungulates, particularly gazelles. Although kites were intensively used during the Early Bronze Age, some of them could have been built and used before that. Beyond these issues, the cultural and socioeconomic aspects of the kites phenomenon are even less understood, and therefore, we focus on changing reasons for the long-lasting use of kites as hunting devices. We contend that the reasons why they were used during the period of utilization for hunting gazelles changed, in most cases, in response to socioeconomic development. It is hypothesized, for example, that, as a result of urban development, kites may have been increasingly (but not exclusively) used to kill gazelles to trade their products with urban communities and farmers, even though they had other uses as well which are also considered. The main hypothesis presented in this article enables diverse opinions about the types of uses and reasons for utilizing desert kites to be reconciled, including in particular varied reasons given in the literature about why they were used for killing gazelles.

This article reviews the extensive history of dynamic performance research, with the goal of providing a clear picture of where the field has been, where it is now, and where it needs to go. Past research has established that job performance does indeed change, but the implications of this dynamism and the predictability of performance trends remain unresolved. Theories are available to help explain dynamic performance, and although far from providing an unambiguous understanding of the phenomenon, they offer direction for future theoretical development. Dynamic performance research does suffer from a number of methodological difficulties, but new techniques have emerged that present even more opportunities to advance knowledge in this area. From this review, I propose research questions to bridge the theoretical and methodological gaps of this area. Answering these questions can advance both research involving job performance prediction and our understanding of the effects of human resource interventions.

Discusses an ongoing programme, the overall purpose of which is to develop an integrated set of stochastic simulation models of firms in the textile, apparel and retail industries. The models are to be used primarily for research, education and industrial problem solving in the areas of plant and company operations with emphasis on Quick Response (QR) methodologies driven by Point‐of‐Sale (POS) data. A second objective is that of developing interactive management information systems using high‐level decision‐surface models (simulation metamodels) of expected system performance as a function of key input parameters.

The size of the population classified as people with disabilities or older adults is increasing globally. The World Health Organization estimates that the average prevalence of disability is around 18% among adults age 18 and older. People with disabilities and older adults have lower levels of physical activity and experience significant barriers to walking in local neighbourhoods. A new perspective is needed that views disability in the context of the built environment and across the lifespan. The purpose of this chapter is to examine walking as an activity that is inclusive of any age, ability or assistive device used for mobility. Through a literature review, we illustrate the complex relationship that exists between individuals with disabilities/older adults and the built environment. We describe environmental and social factors, which have been found to be associated with walking among people with disabilities and older adults as well as factors perceived to be barriers to walking. Factors cited in the literature include aspects that fall into the environmental domains of the International Classification of Functioning. We conclude by highlighting key factors needed for planning supportive walking environments for people with disabilities and older adults. Recommendations include the use of walking audits to gain information on detailed aspects of the built environment, developing inclusive walking initiatives, including people with disabilities and older adults in the planning process and planning for maintenance.

Higher Education (HE) teaching, learning and research require not only cognitive but also emotional commitment from all who are involved in those dialogic processes: the academic and the student. The focus of this chapter is on unexplored territory: emotions at play within undergraduate research (UR) outside the classroom, specifically experienced by students who are engaged in these opportunities for the first time. After reflecting on the problem and bringing together theoretical approaches related to this theme, the authors present a case study, drawing on qualitative data collected in two institutional contexts – one in the UK and other in Portugal. The data analysis leads us to create a framework that addresses the authors’ two research questions, concerning: the emotions that students experience when they are involved in an UR project, and the aspects of that experience the reported emotions relate to. This leads the authors to suggest some recommendations at the end, so they can move toward a more humanized HE experience. This chapter gives an original contribution to discussions on emotions in HE teaching, learning and research in general, and UR in particular.

Typical undergraduate research programs involving HBCU students have several weaknesses including the short time of the students’ involvement in the research and the variable level of commitment of faculty mentors. Another issue at HBCUs is the lack of both start-up support for new faculty and external research support, which limits the quality of research projects and the pool of faculty mentors. We designed our NSF-funded undergraduate research program to be a professional development program to help faculty expand their research program and improve their mentoring skills, while at the same time involving undergraduates in research.

Faculty in STEM departments competed for Student Support Grants that provided support for research-related equipment, supplies, travel, and up to two students for one year. Faculty submitted proposals describing their research project, the role of students in the project, and their student mentoring plan. Faculty mentors could recruit their own students for the project, and both faculty mentors and students were required to commit to the research project for one year.

Outcomes of the program were very positive for both the faculty and the students. All of the involved students presented their research at conferences and several were co-authors on research publications. All but a few of the students continued working in research even after their time in the program was over. In addition, many of the supported faculty members were able to use the financial support as a springboard for successful applications for other grant programs.

The design of work has been shown to influence a host of attitudinal, behavioral, cognitive, well-being, and organizational outcomes. Despite its clear importance, scholarly interest in the topic has diminished over the past 20 years. Fortunately, a recent body of research has sought to reenergize research into work design by expanding our view of work design from a narrow set of motivational work features to one that incorporates broader social and contextual elements. In this chapter we seek to review the literature on work design and develop a framework that integrates both job and team design research. We begin by briefly reviewing the history of work design in order to provide needed historical context and illustrate the evolution of job and team design. We then define work design, particularly as it relates to incorporating job and team design elements and transitioning from a view of jobs to one of roles. Following this, we identify a comprehensive set of work design outcomes that provide the basis for understanding the impact that different work characteristics can have on individuals and teams. We then offer an extended discussion of our integrative model of work design, which includes three sources of work characteristics (task, social, and contextual) and the worker characteristics implied by these characteristics. Having defined the range of work and worker characteristics, we then discuss some of the fit and composition issues that arise when designing work, as well as discuss the mechanisms through which the work characteristics have their impact on outcomes. Finally, we discuss research into informal forms of work design.

This chapter examines experts’ perceptions of the conditions of their entrepreneurial ecosystems to analyse women’s disadvantages, identify which conditions can improve in comparison to men in Latin America, and if the level of development of their country affects the support women entrepreneurs have. The study is based on regional data collected in Chile and Mexico with one of the Global Entrepreneurship Monitor surveys between 2015 and 2018. With a total sample of N = 2,230 male and female experts, the author uses principal component analysis and non-parametric statistics to compare means between genders and also women in different countries. First, male and female experts’ perceptions are compared at the macrolevel and then total women as a subsample are compared between the women experts’ perceptions by country at the mesolevel. At the macrolevel, the results show a clear perceived disadvantage for women entrepreneurs in all conditions except internal market dynamics. At the mesolevel, the findings show that support for women entrepreneurs is better in most conditions for Mexico, which is a less developed country, in comparison to Chile for this case. This chapter goes from studying the general to the particular issues causing gender gaps in entrepreneurial ecosystems in developing Latin American countries. The dataset used represents the biggest data-gathering project in the field of entrepreneurship for the region.

In this chapter, we outline the evidence regarding the status effects of physical attractiveness in the workplace. We frame the effects of attractiveness as power and status dynamics shaped by the context of the workplace. Attractiveness serves as a social status that mostly provides benefits in the workplace, although the results are not uniformly positive. We first explain attractiveness as a status characteristic and how it operates in general social interactions. We then examine these effects across three typical yet significant career development milestones in a worker's life: (1) the selection and hiring process of employment, (2) day-to-day interactions with colleagues and co-workers and (3) in leadership roles and positions.
