Breaking Time

Flowing grains can clog an orifice by developing arches, an undesirable event in many cases. Several strategies have been put forward to avoid this. One of them is to vibrate the system in order to undo the clogging. Nevertheless, the time taken to break an arch under a constant vibration has a distribution displaying a heavy tail. This can lead to a situation where the average breaking time is not well defined. Moreover, it has been observed in some experiments that these tails tend to flatten for very long times, exacerbating the problem. Here we will review two conceptual frameworks that have been proposed to understand the phenomenon and discuss their physical implications.

Management And Leadership

"Management" and "leadership" are currently two buzz words in the Canadian LIS community. Although these topics receive scholarly attention, epistemological and theoretical basis for that work is limited. LIS needs to expand the conceptual frameworks used to study these topics by looking to the discipline of Educational Administration and Leadership.La gestion et le leadership sont des mots à la mode au sein de la communauté canadienne des sciences de l'information. Malgré toute l'attention que leur accorde la recherche universitaire, les bases épistémologiques et théoriques pour en parler sont limitées. La communauté des sciences de l'information doit élargir le cadre conceptuel d'étude de ces sujets en se basant sur l'administration et le leadership en milieu scolaire.

The Way

This book is concerned with the way in which forces of change, from the fields of finance and non-financial corporates, cause participants in the corporate reorganization process to adapt the ways in which they mobilize corporate reorganization law. It argues that scholars, practitioners, judges, and the legislature must all take care to connect their conceptual frameworks to the specific adaptations which emerge from this process of change. It further argues that this need to connect theoretical and policy concepts with practical adaptations has posed particular challenges when US corporate reorganization law has been under examination in the decade since the financial crisis. At the same time, the book suggests that English scholars, practitioners, judges, and the legislature have been more successful, over the course of the past ten years, in choosing concepts to frame their analysis which are sensitive to the ways in which corporate reorganization law is currently used. Nonetheless, it suggests that new problems may be on the horizon for English corporate reorganization lawyers in adapting their conceptual framework in the decades to come.

And Performance

Creative practice in music takes place in a distributed and interactive manner embracing the activities of composers, performers and improvisers—despite the sharp division of labour between these roles that traditional concert culture often presents. Two distinctive features of contemporary music are the greater incorporation of improvisation and the development of integrated and collaborative working practices between composers and performers. By blurring the distinction between composition and performance, improvisation and collaboration provide important perspectives on the distributed creative processes that play a central role in much contemporary concert music. This volume explores how collaboration and improvisation enable and constrain these creative processes. Organized into three parts, thirteen chapters and twelve shorter Interventions present diverse perspectives on distributed and collaborative creativity in music, on a range of collaborations between composers and performers, and on the place of improvisation within contemporary music, broadly defined. The thirteen chapters provide more substantial discussions of a variety of conceptual frameworks and particular projects, while the twelve Interventions provide more informal contributions from a variety of practitioners (composers, performers, improvisers), giving direct insights into the pleasures and problems of working creatively in music in collaborative and improvised ways.

Transport Of Dangerous Goods

This article discusses the issues related to the safety for the transport of dangerous goods by road. Research on accidents in transport unambiguously points to the human factor, which is the most responsible for causing accidents. Determining the causes of driver unreliability in the human−vehicle−environment system requires thorough research. Unfortunately, in this case, experimental research with human involvement is limited in scope. This leaves modeling and simulation of the behavior of the human factor, i.e., the driver transporting dangerous goods. The human being, because of its complexity, is a challenging element to parameterize. The literature presents various attempts to model human actions. Herein, the authors used heuristic methods, specifically fuzzy set techniques, to build a human factor model. In these models, human actions were specified using a verbal or linguistic description. The specificity of the fuzzy sets allowed for “naturally” limiting the “precision” in describing human behavior. The model was built based on the author’s questionnaire and expert research, based on which individual features were selected. Then, the traits were assigned appropriate states. The output parameter of the model was λL—the intensity of human error. The obtained values of the intensity of the accident caused by the driver’s error were implemented into the author’s method of risk assessment. They constituted one of the factors determining the probability of an accident in the transport of dangerous goods, which allowed for determining the optimal route for the transport of these goods characterized by the lowest risk of an undesirable event on the route. The article presents the model’s assumptions, structure, and the features included in the model, all of which have the most significant influence on shaping the intensity of human error. The results of the simulation studies showed a diversified effect of the analyzed characteristics on the driver’s efficiency.

Risk Appraisal

Unintentional injury is a significant worldwide health concern. Researchers have called on several occasions for conceptual frameworks to guide work on unintentional injury. Using conceptual approaches to organize our inquiry is one way to advance our knowledge of injury etiology. To this end, we suggest a risk appraisal framework for examining enactment or avoidance of injury risk behaviors. Our framework comprises broad antecedents, focusing on the evaluative stage preceding behaviors. Four categories influencing efficacy related to injury risk behavior are included: environmental context, experience, social context, and strategy. In this article, we explain the categories and concepts in our framework, discuss each in terms of etiology, briefly discuss interrelations between the categories, and suggest future paths using the framework.
