The purpose and nature of management scholarship is contested, evidenced by debates about the ‘academic–practitioner divide’ and attendant remedies for addressing it, including mode 2 and mode 3 research, engaged scholarship, evidence‐based management and design science. In this paper the authors argue that, without a culture of dialogical encounter, management scholarship will never be able to emerge from its adolescence, and management will not develop into the profession that it should and can become. The central proposition is that the highly fragmented landscape of management (practice and scholarship) lacks sufficient capability for dialogue among the plurality of actors situated across that landscape. Developing the dialogical capability ultimately required to break this fundamental impasse demands, first, a shared sense of purpose and responsibility (akin to the Hippocratic Oath in medicine) and, second, institutional entrepreneurship to establish more and better ‘trading zones’. Drawing on the philosophy of pragmatism, the authors further this endeavour by identifying and proposing key elements of a statement of shared purpose and responsibility. Finally, they explore the nature and characteristics of successful trading zones, highlighting particular examples that have already been created in management studies.  相似文献

Current industrial processes are sophisticated enough to be tied to only one quality variable to describe the process result. Instead, many process variables need to be analyze together to assess the process performance. In particular, multivariate process capability analysis (MPCIs) has been the focus of study during the last few decades, during which many authors proposed alternatives to build the indices. These measures are extremely attractive to people in charge of industrial processes, because they provide a single measure that summarizes the whole process performance regarding its specifications. In most practical applications, these indices are estimated from sampling information collected by measuring the variables of interest on the process outcome. This activity introduces an additional source of variation to data, that needs to be considered, regarding its effect on the properties of the indices. Unfortunately, this problem has received scarce attention, at least in the multivariate domain. In this paper, we study how the presence of measurement errors affects the properties of one of the MPCIs recommended in previous researches. The results indicate that even little measurement errors can induce distortions on the index value, leading to wrong conclusions about the process performance.  相似文献

How do low socioeconomic status students navigate cross-class interactions in extremely unequal contexts? Previous research has described the high costs of college integration for underprivileged students, which in turn, negatively impact academic performance and general wellbeing. These studies tend to concentrate on cultural capital costs, such as catching up with assumed middle-class or elite capital and dealing with two worlds. Less has been said about social capital costs, the costs of making friends, especially more privileged friends. Through 61 in-depth interviews with various types of students as part of a broader ethnographic fieldwork, this article analyses the experiences of low-income scholarship holders in an elite institution in a very unequal society, Colombia. Rather than isolating themselves or resorting to safe homophilic relations, they faced their new elite environment engaging with the hidden relational cost of making friends with more affluent students. In so doing, they had to overcome fears and experiences of discrimination and micro-aggressions, as well as cultural and economic capital barriers, and employed either camouflaging or disclosure strategies, sometimes becoming culturally and socially omnivorous. Symbolic belonging to the institution and the acquisition of middle-class cultural capital were among the benefits that made overcoming the costs worthy. Our results shed light on what institutions can do to reduce the costs for underprivileged students and, theoretically, unveil an important mechanism and barrier for social mobility: building cross-class ties.  相似文献

Urbanization usually reduces bat richness; however, the presence of green areas within cities and peripheral rural areas in arid ecosystems may provide microhabitats for some species. Light pollution is a major feature of urbanization, but its impact on bat behavior appears to be species-specific and previous studies have documented contrasting responses. Moreover, the effect of urbanization on bat species has been poorly studied in arid regions. We assessed the effect of artificial night light intensity (as a proxy of urbanization) on both bat occupancy and the acoustic space used (ASU) in an urbanization gradient in Peruvian central coast, based on passive acoustic recorders. We collected 26,169 recordings from 19 sites which resulted in 579 independent detections of 15 bat species. Variation in both ASU and species richness was best explained by artificial night light intensity. Species-specific effects of the artificial night light intensity based on a multi-species occupancy modeling showed that this covariate had a negative effect on occupancy for most of the bat species (12 species). ASU and both observed and posterior bat species richness were positively correlated, suggesting that ASU can be used as a proxy of bat richness. This study provides evidence that both bat richness and occupancy decrease with artificial light intensity; nevertheless, eight species used urban areas, similar to results found in other cities around the world.

This article presents the results of a longitudinal study that followed a sample of 1011 young people who completed their secondary technical and vocational education and training studies in Chile between 2011 and 2016. It adopts a mixed design that combines both quantitative and qualitative methodological strategies to analyse transitions and post-study trajectories. Analysis has helped to identify the prevalence of non-linear and unstructured transitions to the labour market. It has also shown the existence of education-work links and employment alternatives that are generated in certain sectors as well as identified how these give rise to specific opportunity structures that affect on aspirations and career pathways. Results indicate that graduates of the industrial area of study experience more substantive educational integration and labour links following course completion due to greater levels of alignment between their training and the productive demands of the industrial sectors. However, their experiences over the medium term are fragmented and, thus, reflect those of their peers from other areas.  相似文献

Research shows that the labour market integration of refugees is often problematic. Little is known about what kind of measures are effective to help them integrate into the labour market. In the Netherlands, a positive psychology intervention “Mosaic” for Syrian refugees was developed to support their economic participation. This study aims to assess the effect of “Mosaic” on the economic participation and work-related attitudes of Syrian refugees. “Mosaic” was implemented in six municipalities by conducting an RCT with a waiting list control group. The results show that in the short term, the intervention group realizes a significantly larger increase in hours spent on an internship as well as substantially larger gains in confidence to find work in the future. In the long term, the intervention group experiences larger confidence gains related to finding a job that fits their education and experience.  相似文献
