Development and validation of a lean supply chain management measurement instrument

It is widely argued that to be competitive, a company not only needs to focus on internal aspects but on the entire supply chain. Lean supply chain management has become a means of enhancing competitiveness by improving efficiency and increasing flexibility at all stages of the supply chain. This research develops and validates a lean supply chain management measurement instrument. A two-phase approach is used for scale development and refinement. In the first phase, a literature review is conducted to identify definitions of lean supply chain management and agile supply chain management and their corresponding measurement items. In the second phase, the lean supply chain management measurement instrument is validated using survey data based on scales developed in the first phase by 59 scholars with experience in lean management and/or supply chain management. The results provide a structured and comprehensive measure of lean supply chain management indicating that there are two differentiated dimensions in the measurement instrument: one related to the operational aspects of lean supply chain strategy implementation and the second related to lean supply chain planning.

Necessary Disruptions: A Discussion of Daniel Butler’s “Racialized Bodies and the Violence of the Setting”

This discussion of Daniel Butler’s article “Racialized Bodies and the Violence of the Setting” takes up the importance of the concept of place, largely through the lens of Frantz Fanon. It argues that being is best understood as being placed, emphasizing the necessity of material and historical setting for any ontological formation. Very tentatively, it advances a fragile hope that Whiteness is currently being placed in a way that can no longer be regarded as something universalized and invisible.     

Separating thoughts from the self by selling them to others: the moderating role of self-esteem / Separar los pensamientos del yo al venderlos a otros: el rol moderador de la autoestima

Abstract

This research introduces a new approach for separating people from their thoughts by anticipating selling them to others. Participants were asked to write down either positive or negative thoughts about fast food on different pieces of paper. Then, participants were randomly assigned to role-play the part of either potential buyers or sellers for an advertising campaign. Finally, all participants indicated their self-esteem (as an additional predictor) and their attitudes towards fast food (as the dependent measure). For high self-esteem participants, anticipating selling thoughts to others reduced the impact of thoughts on attitudes, suggesting that distancing thoughts from a location with high validity (the self) reduced the perceived value of their thoughts. In contrast, for low self-esteem participants, anticipating selling thoughts increased their usage, suggesting that separating thoughts from a location with low validity (the self) increased the perceived value of those thoughts. These findings suggest that thoughts can be associated with high or low validity depending on individual differences in self-esteem.

Renaissance of a rural artifact in a city with a million people: biodiversity responses to an agro-forestry restoration in a large urban traditional fruit orchard

The rural landscapes surrounding large cities are rapidly becoming incorporated into the urban environment. The most conspicuous changes involve green spaces, such as former agro-forestry systems like fruit orchards. In this paper, we assess the influence on biodiversity of restoring a large urban traditional fruit orchard as reflected by six selected taxa: plants, lichens, butterflies, beetles, orthopteroids and birds. The study was performed in Prague, which is the capital city of the Czech Republic and has more than a million inhabitants. We studied the effect of orchard renewal in 45 patches (15 for birds and 30 for other taxa). The majority of taxa responded positively to the restoration. The restoration had a significant positive effect on the species richness of lichens, butterflies and beetles. All taxa showed significantly altered species compositions, and the number of red-listed species increased. Orchards have a high potential for multi-functional use. Orchards are productive agro-forestry systems and host numerous possible human activities. Therefore, orchard restoration also has a social aspect. Moreover, our research in this artificial ecosystem revealed that its restoration increased the biodiversity and conservation potential of the associated areas.

     

The Twitter games: media education,popular culture and multiscreen viewing in virtual concourses

Interactive media and virtual environments give rise to transmedia and multiscreen viewing in a new popular and participatory culture. This in turn requires a new type of critical, reflective media education. This article reviews expert opinions on the educational potential of The Hunger Games (THG) and the use of Twitter during the viewing of films by young audiences. The study has the twofold goal of analysing whether the tweets include the topics of ideology and values mentioned in the selected articles and whether the conversations help build knowledge of the subjects that, according to the experts, are discussed in the literary trilogy. The method, based on discourse analysis, is twofold as well, comprising, on one hand, the discussion of 61 selected academic papers on THG and, on the other, 6000 tweets posted by youngsters while watching the films in the trilogy shown on TV. The tweets were analysed using the ‘coding and counting’ technique in computer-mediated discourse analysis. The results show a great chasm between academic or educational perspectives and what youngsters see in the films. Twitter interactions show that the virtual environments where these interactions take place are mere virtual concourses rather than affinity or learning spaces. This draws attention to the need for a new type of media education which not only includes the popular culture in formal education environments, but also uses the virtual concourses where youngsters gather around media products to transform mere coexistence into convergence of interests based on the meaning of these products.     

University environment and entrepreneurial intention: the mediating role of the components of the theory of planned behaviour / El entorno universitario y la intención emprendedora: el papel mediador de los componentes de la teoría de la acción planificada

Entrepreneurship contributes to job creation and economic development. Thus, it is important to promote entrepreneurial initiatives; universities play a key role in this regard. The psychosocial perspective can contribute a great deal to studying the antecedents that lead a person to become an entrepreneur, with the theory of planned behaviour (TPB) being the theoretical framework used the most to predict entrepreneurial intention. Based on the data collected in Spain as part of the international GUESSS project (Global University Entrepreneurial Spirit Students’ Survey) with a sample of 9,753 students, the influence of the university environment, the entrepreneurial environment and the perceived risk of entrepreneurship on entrepreneurial intention are analysed, both directly and as mediated by the three components of the TPB (attitudes towards entrepreneurship, subjective norms and entrepreneurial self-efficacy). The results show that the university environment is the antecedent with the greatest effect on entrepreneurial intention; therefore, it is recommended that entrepreneurship be promoted through initiatives and educational programmes in the university environment.     

Trust and Hometown Associations in Haitian Post‐Earthquake Reconstruction

The 7.0 magnitude earthquake on January 12, 2010 in Haiti reawakened in the diaspora a strong sense of purpose to focus efforts beyond family remittances towards regional and national development. Yet Haitian hometown associations (HHTAs) in the US struggled to establish a strong, organizational structure to respond systematically and effectively to the country's increased post‐earthquake needs. Based on historical analysis, participatory observations, interviews, and comparisons with other diaspora groups’ models for homeland development, we explore how trust within the transnational Haitian nation has been impacted in the post‐earthquake era by cultural conditionings of the past which constrain the scalability, durability, and viability of HHTAs’ developmental potential to systematically intervene in a coordinated manner regionally and nationally. We examine the ways in which trust – and resistances to it – operates as a mediating lens remobilized by the earthquake for the interpretation of the Haitian past, present, and future.
