In the future the air traffic will rise--the workload of the controllers will do the same. In the BMWi research project, one of the tasks is, how to ensure safe air traffic, and a reasonable workload for the air traffic controllers. In this project it was the goal to find ways how to reduce the workload (and stress) for the controllers to allow safe air traffic, esp. at huge hub-airports by implementing augmented reality visualization and interaction. 相似文献

This study reviews literature on paradoxical tensions between value co‐creation and capture in interorganizational relationships (IORs). The purpose of this review is to make a re‐evaluation of the literature by engaging a paradox theory lens, thereby identifying factors that render tensions salient and factors that lead to virtuous or vicious cycles. This review of 143 articles reveals factors that make tensions salient: these relate to plurality (e.g. coopetition), scarcity (e.g. lack of experience with IORs), change (e.g. changes in collaboration scope) or combinations thereof (e.g. IORs in weak appropriability regimes). Results also uncover factors that resolve paradoxical tensions of value co‐creation and capture, thus spurring virtuous cycles (e.g. carefully mixing trust and contracts), as well as factors that promote vicious cycles, owing to the emphasis on either value co‐creation or capture (e.g. myopia of learning). This review further reveals a new category of factors that may stimulate either virtuous or vicious cycles, depending on the extent to which they are enforced. This finding expands the value co‐creation–capture paradox resolution and brings to light new dynamics in the paradox framework of dynamic equilibrium. This study thus contributes by: (1) reassessing the existing literature and applying paradox theory to the well‐known hazard of value co‐creation and capture; (2) highlighting factors that amplify paradoxical tensions related to this hazard; and (3) outlining factors that help solve the paradox by embracing its contradictory poles and factors that hinder paradox resolution by emphasizing either value co‐creation or appropriation. 相似文献

Environmental practices have not received as much research attention in emerging market contexts as traditional topics like quality. However, the importance of environmental practices for a firm’s production strategy has been increasing at an unprecedented level across the globe. Our research objective is, therefore, to investigate the interplay between environmental practices and quality in the pursuit of firm performance. Relying on 492 responses from Turkish manufacturers to test our hypotheses, we show that environmental practices directly improve the quality of products over and above the effect of quality management practices in emerging markets. Product quality, in turn, is important for increasing firm performance, acting as a mediator for the positive effects of environmental practices on performance. Thus, we reveal that product quality functions as an instrumental conduit between environmental practices and firm performance in emerging markets like Turkey where stakeholder pressures are weak, and regulations are often not properly enforced. 相似文献

This study conceptually and empirically extends a study by Wotanis and McMillan in which the authors claimed that female video producers are underrepresented on YouTube and receive much more negative (including hostile and sexist) feedback than male YouTubers. Using quantitative content analysis, this study supported the claim of female underrepresentation. Among the top 100 most subscribed YouTube channels in nine different countries (N = 900 channels), with a statistically significant proportion of only 25%, female video producers were strongly underrepresented. Additionally, a second content analysis of N = 2,400 video comments directly replicated the original study’s main quantitative results. This analysis confirmed that the popular female US comedy YouTuber Jenna Mourey (“JennaMarbles”) received much more negative (including hostile and sexist) feedback than her male counterpart Ryan Higa (“nigahiga”). However, a third content analysis of N = 6,000 video comments from five other pairs of comparable comedy YouTubers did not reveal that women’s videos generally attract a larger number of negative video comments. Possibly, women attract more negative comments only if they display their sexuality (like Jenna Mourey) or address feminist topics, but not if they conform to gender role expectations. Future research directions and practical implications are discussed. 相似文献

In the aftermath of the financial crisis that hit Iceland in October 2008, increased numbers of Icelanders migrated to Norway to seek employment due to difficult economic circumstances in Iceland. Using critical perspectives from postcolonial studies and critical whiteness studies, the paper explores how these Icelandic migrants in Norway make sense of their new position as economic migrants within a global economy characterised by a growing sense of precariousness, while past inequalities and racism continue to matter. We also examine how these migrants are perceived in Norwegian media, and how social discourses of Icelandic migrants reflect larger Norwegian debates on racism, desirability and cultural belonging. Media discourses in Norway and interviews with Icelandic migrants reveal a hierarchy of acceptability of migrants. Icelanders are positioned as highly desirable compared to other migrant groups due to the intersection of perceived racial belonging, nationality and class. Our discussion contributes, furthermore, towards a critical analysis of the category migrant, by exploring how the term immigrant (innvandrer/innflytjandi) is used in narratives of Icelandic migrants in Norway and in Norwegian media discussions, showing the negative and racialised connotations of the term immigrant and how its understanding is linked with vulnerable positions and discrimination. 相似文献

Sleep problems are common and impair the health and productivity of employees. Work characteristics constitute one possible cause of sleep problems, and sleeping poorly might influence wellbeing and performance at work. This study examines the reciprocal associations between sleep problems and psychosocial work characteristics. The participants were 1744 full-time employed individuals (56% women; mean age 38 years in 2007) from the Young Finns study who responded to questionnaires on work characteristics (conceptualised by the demand–control model and effort–reward imbalance model) and sleep problems (Jenkins Sleep Scale) in 2007 and 2012. Cross-lagged structural equation models are used to examine the associations. The results show that low control and low rewards at baseline predicted sleep problems. Baseline sleep problems predicted higher effort, higher effort–reward imbalance, and lower reward. Sleep problems also predicted lower odds for belonging to the low (rather than high) job strain group and active jobs group. The association between work characteristics and sleep problems appears to be reciprocal, with a stressful work environment increasing sleep problems, and sleep problems influencing future work characteristics. The results emphasise the importance of interventions aimed at both enhancing sleep quality and reducing psychosocial risks at work. 相似文献

AbstractThe ongoing digital transformation on industry has so far mostly been studied from the perspective of cyber-physical systems solutions as drivers of change. In this paper, we turn the focus to the changes in data management resulting from the introduction of new digital technologies in industry. So far, data processing activities in operations management have usually been organised according to the existing business structures inside and in-between companies. With increasing importance of Big Data in the context of the digital transformation, the opposite will be the case: business structures will evolve based on the potential to develop value streams offered on the basis of new data processing solutions. Based on a review of the extant literature, we identify the general different fields of action for operations management related to data processing. In particular, we explore the impact of Big Data on industrial operations and its organisational implications. 相似文献
