Accidents Will Happen. Do Safety Systems Improve Warehouse Safety Performance?

Safety is becoming more and more an issue in warehouses. In the literature, effective measures leading to increased occupational health and safety have hardly been researched. Most research focuses on the impact of perceived safety-related leadership of managers and worker safety consciousness on ‘safety climate’ and workers’ safe behavior. We have carried out exploratory research into which measures really improve the safety performance of a warehouse. We particularly focus on the effects of (1) safety-related work procedures, (2) safety leadership, and (3) workers’ safety consciousness. Based on a survey we show that safety leadership and safety-related work procedures significantly drive worker safety consciousness, which in turn positively impacts safety performance

An Evaluation of Cross-Efficiency Methods, Applied to Measuring Warehouse Performance

In this paper method and practice of cross-efficiency calculation is discussed. The main methods proposed in the literature are tested not on a set of artificial data but on a realistic sample of input-output data of European ware- houses. The empirical results show the limited role which increasing automation investment and larger warehouse size have in increasing productive performance. The reason is the existence of decreasing returns to scale in the industry, resulting in sub-optimal scales and inefficiencies, regardless of the operational performance of the facilities. From the methodological perspective, and based on a multidimensional metric which considers the capability of the various methods to rank warehouses, their ease of implementation, and their robustness to sensitivity analyses, we conclude to the superiority of the classic Sexton et al. (1986) method over recently proposed, more sophisticated methods

An evaluation of cross-efficiency methods: With an application to warehouse performance

Cross-efficiency measurement is an extension of Data Envelopment Analysis that allows for tie-breaking ranking of the Decision Making Units (DMUs) using all the peer evaluations. In this article we examine the theory of cross-efficiency measurement by comparing a selection of methods popular in the literature. These methods are applied to performance measurement of European warehouses. We develop a cross-efficiency method based on a rank-order DEA model to accommodate the ordinal nature of some key variables characterizing warehouse performance. This is one of the first comparisons of methods on a real-life dataset and the first time that a model allowing for qualitative variables is included in such a comparison. Our results show that the choice of model matters, as one obtains statistically different rankings from each one of them. This holds in particular for the multiplicative and game-theoretic methods whose results diverge from the classic method. From a managerial perspective, focused on the applicability of the methods, we evaluate them through a multidimensional metric which considers their capability to rank DMUs, their ease of implementation, and their robustness to sensitivity analyses. We conclude that standard weight-restriction methods, as initiated by Sexton et al. [48], perform as well as recently introduced, more sophisticated alternativesSpanish Ministry of Science and Innovation (Ministerio de Ciencia e Innovación), the State Research Agency (Agencia Estatal de Investigación) and the European Regional Development Fund (Fondo Europeo de Desarrollo Regional) under grants EIN2020-11226

Balancing demands and resources in sport:adaptation and validation of the demand-induced strain compensation questionnaire for use in sport

Too high demands, combined with a lack of resources, are often detrimental to athletic health and well-being. However, a valid and reliable instrument to investigate different dimensions of demands and resources in sport is currently unavailable. Therefore, the present study examines the psychometric properties of an existing and well-validated survey instrument on demands and resources at task-level that was adapted to sport. This instrument, the Demand-Induced Strain Compensation Questionnaire for Sport (DISQ-SPORT), was empirically tested among 1,101 athletes (416 females and 685 males) from a variety of sports and in different languages. Results supported the proposed six-factor structure of the instrument, consisting of physical, cognitive, and emotional demands and resources. Internal consistencies of all subscales were satisfactory and the instrument was invariant across type of sport, competitive level and language. Continued evaluation of the psychometric properties of the DISQ-SPORT, especially in terms of content validity and test-retest stability, is nevertheless warranted. Theoretical and practical implications as well as areas for future research are discussed.</p

Transtorno Opositor Desafiador: estratégias e concepções pedagógicas no processo de ensino-aprendizagem de uma escola pública do município de Uruguaiana/RS

O Transtorno opositor desafiador (TOD) é um transtorno disruptivo, do controle de impulsos e da conduta, caracteriza-se por um padrão de comportamentos hostis, desafiadores e desobedientes, iniciados normalmente entre seis e oito anos de idade. Crianças com essa faixa etária estão nos primeiros anos do ensino fundamental, etapa importante da escolarização e alfabetização a qual prioriza o desenvolvimento intelectual e pessoal. Estabelecer estratégias que atendam as práticas inclusivas pelos docentes facilita o processo de ensino-aprendizagem para atender às necessidades dessas crianças. O objetivo geral deste estudo foi investigar a concepção sobre TOD e as estratégias pedagógicas utilizadas por professores no processo de ensino-aprendizagem destes estudantes nos anos iniciais do Ensino Fundamental I. Trata-se de um estudo transversal, descritivo exploratório de abordagem qualitativa, composto por 14 professores dos anos iniciais de 1 escola da rede pública municipal de ensino de Uruguaiana/RS. Como técnica de coleta de dados, foi realizada uma entrevista semiestruturada e observações através de um diário de campo. Os resultados foram discutidos à luz da análise de conteúdo de Bardin (2011) e apontam a importância do tema para a sociedade. Os resultados gerados mostram a falta de políticas públicas (legislação, estudos científicos, divulgação) voltadas ao atendimento da criança com TOD no ambiente escolar, bem como as fragilidades e barreiras enfrentadas pelos professores. Assim, evidenciando a necessidade de formações específicas de forma permanente e/ou contínua para a inclusão efetiva de crianças com o transtorno em um ambiente oportuno de ensino-aprendizagem, favorecendo todo âmbito escolar em que esteja inserida

Investigating Historical Abuses: An Applied History Perspective on intercountry Adoption in the Netherlands, 1950s-Present

This article investigates the phenomenon and practice of intercountry adoption from a historical perspective by using applied history methods. In particular, we employed the method of historicizing current concerns, such as the notion of abuses, and contextualizing them in history. With these methods, we contributed to the Dutch governmental assessment and evaluation of intercountry adoption, indicating that our findings (as laid down in the official report) need to be translated into revised governmental policies. In this paper, we describe how we applied our historicizing methods to intercountry adoption abuses by providing a narrative and genealogy of the topic. We also discuss the pitfalls and merits of conducting historical research into practices that are now considered immoral or unjust, but were long standard practice after intercountry adoption started in the Netherlands. In this way, we also contribute to the ongoing discussion on doing historical research in highly politicized contexts, where the danger of contributing to the ‘blame game’ often lies in wait

Accidents Will Happen: Do Hazard – Reducing Systems Help?

In the summer of 2009, soon after the winners of the annual Safest Warehouse of the Year Awards were being lauded at an industry conference, journalist Marcel te Lindert wondered out loud in his regular column for the Dutch maga- zine Logistiek, why it was that there were more questions raised about safety issues than there were answers
