Mobile Assistenzsysteme für Industrie 4.0: Gestaltungsoptionen zwischen Autonomie und Kontrolle

Der Beitrag rückt die mit der zunehmenden Verbreitung digitaler Assistenzsysteme - wie Smart Glasses, digitale Uhren oder Tablets - einhergehenden Folgen für Industriearbeit unter dem Aspekt der Arbeitskontrolle in den Fokus. Unter Assistenzsystemen werden mobile Geräte verstanden, die Arbeitsanweisungen, Lerninhalte und Informationen audiovisuell aufbereiten. Zu den typischen Anwendungsgebieten zählen Kommissionierung, Montage sowie Instandhaltung. Neben einer überblickshaften Darstellung von Assistenzsystemen und ihren Einsatzgebieten richtet sich der Blick insbesondere auf die Frage nach den betrieblichen Einsatzgründen, die zwischen Disziplinierung der Beschäftigten auf der einen und Erweiterung der Entscheidungs- und Handlungsspielräume der Beschäftigten auf der anderen Seite variieren können. Anhand von zwei Unternehmensfällen werden diese Gestaltungsoptionen exemplarisch verdeutlicht. Abschließend werden Herausforderungen bei der betrieblichen Einführung und arbeitspolitische Implikationen abgeleitet.This paper focusses on digital assistance systems, like smart glasses, digital watches or tablets, regarding their effects on labour. Assistance systems are understood to be mobile devices that deliver work instructions, educational content and information audio-visually. Typical application areas rank among commissioning, assembly and maintenance. Besides the presentation of assistance systems and their application areas, the focus is pointed especially at the question concerning the operational application reasons. These can vary from disciplinary measures against employees on the one side to the extension of employees' scope for action and decision on the other side. On the basis of two business cases the configuration options are illustrated exemplary. Finally, challenges for the operational introduction and implications regarding labour-policy are derived

A Flexible Framework for the Creation of Narrative-Centered Tools

To better support the creation of narrative-centered tools, developers need a flexible framework to integrate, catalog, select, and reuse narrative models. Computational models of narrative enable the creation of software tools to aid narrative processing, analysis, and generation. Narrative-centered tools explicitly or implicitly embody one or more models of narrative by their definition. However, narrative model creation is often expensive and difficult with no guaranteed benefit to the end system. This paper describes our preliminary approach towards creating the SONNET narrative framework, a flexible framework to integrate, catalog, select, and reuse narrative models, thereby lowering development costs and improving benefits from each model. The framework includes a lightweight ontology language for the definition of key terms and interrelationships among them. The framework specifies model metadata to allow developers to discover and understand models more readily. We discuss the structure of this framework and ongoing development incorporating narrative models

Le Sujet de l’Acteur. An Anthropological Outlook on Actor-Network Theory

In the past few years, the Actor-Network Theory of French philosopher and sociologist Bruno Latour has become a hotly debated topic in the humanities. From a philosophical perspective, his theory of things keeps being reevaluated: is it possible for ‘Human and Non-Human Actors’ (Latour) to be analyzed as equally important actors? Does Latour’s theory of a simultaneous ‘agency’ of things and concepts indeed move beyond a subject-object relation? If it does, how far does it in fact go? Is it possible to develop a common new ontology by moving away from the notion of substance, and instead reducing any kind of entities to what they reveal in the course of their (inter)action? The contributions to Le Sujet de l’Acteur are looking for interferences between the idea of ‘agency’ and cultural dynamics. How can we relate questions of (social) action with those of cultural manifestations? Focusing on questions of symmetry or dissymmetry between the world of ‘things’ and ‘human beings,’ the volume includes contributions from the fields of social studies, literary studies, and philosophy. Although the contents are categorized in systematic and historical aspects, all contributions draw on the importance of case studies for the theoretical framework, either starting with systematic questions that are then answered exemplary, or starting from historical cases as well as theoretical options

A standardized, evidence-based protocol to assess clinical actionability of genetic disorders associated with genomic variation

Genome and exome sequencing can identify variants unrelated to the primary goal of sequencing. Detecting pathogenic variants associated with an increased risk of a medical disorder enables clinical interventions to improve future health outcomes in patients and their at-risk relatives. The Clinical Genome Resource, or ClinGen, aims to assess clinical actionability of genes and associated disorders as part of a larger effort to build a central resource of information regarding the clinical relevance of genomic variation for use in precision medicine and research

Investing in the future: lessons learnt from communicating the results of HSV/ HIV intervention trials in South Africa

<p>Abstract</p> <p>Background</p> <p>Communicating the results of randomised controlled trials may present challenges for researchers who have to work with communities and policy-makers to anticipate positive outcomes, while being aware that results may show no effect or harm.</p> <p>Methods</p> <p>We present a case study from the perspective of researchers in South Africa about the lessons learnt from communicating the results of four trials evaluating treatment for herpes simplex virus type 2 (HSV-2) as a new strategy for HIV prevention.</p> <p>Results</p> <p>We show that contextual factors such as misunderstandings and mistrust played an important role in defining the communications response. Use of different approaches in combination was found to be most effective in building understanding, credibility and trust in the research process. During the communication process, researchers acted beyond their traditional role of neutral observers and became agents of social change. This change in role is in keeping with a global trend towards increased communication of research results and presents both opportunities and challenges for the conduct of future research.</p> <p>Conclusions</p> <p>Despite disappointing trial results which showed no benefit of HSV-2 treatment for HIV prevention, important lessons were learnt about the value of the communication process in building trust between researchers, community members and policy-makers, and creating an enabling environment for future research partnerships.</p

Civil society leadership in the struggle for AIDS treatment in South Africa and Uganda

Includes abstract.Includes bibliographical references.This thesis is an attempt to theorise and operationalise empirically the notion of ‘civil society leadership’ in Sub-Saharan Africa. ‘AIDS leadership,’ which is associated with the intergovernmental institutions charged with coordinating the global response to HIV/AIDS, is both under-theorised and highly context-specific. In this study I therefore opt for an inclusive framework that draws on a range of approaches, including the literature on ‘leadership’, institutions, social movements and the ‘network’ perspective on civil society mobilisation. This framework is employed in rich and detailed empirical descriptions (‘thick description’) of civil society mobilisation around AIDS, including contentious AIDS activism, in the key case studies of South Africa and Uganda. South Africa and Uganda are widely considered key examples of poor and good leadership (from national political leaders) respectively, while the Treatment Action Campaign (TAC) and The AIDS Support Organisation (TASO) are both seen as highly effective civil society movements. These descriptions emphasise ‘transnational networks of influence’ in which civil society leaders participated (and at times actively constructed) in order to mobilise both symbolic and material resources aimed at exerting influence at the transnational, national and local levels

Cannabis use and abuse correlates in a homogeneous South African schizophrenia population

CITATION: Koen, L., Jonathan, R. & Niehaus, D. J. H. 2009. Cannabis use and abuse correlates in a homogeneous South African schizophrenia population. South African Journal of Psychiatry, 15(1):8-12, doi:10.7196/sajp.99.The original publication is available at http://www.sajp.org.zaObjective. Worldwide, cannabis is the most widely used illicit substance, and it has been identified as a correlate in schizophrenia samples for poorer symptomatic and functional outcomes in many international studies. The object of this retrospective study was to identify the prevalence of cannabis use/abuse and the demographic and clinical correlates therefor in a large homogeneous South African schizophrenia population. Methods. As part of a large genetic study, 547 subjects with a diagnosis of schizophrenia were recruited. Demographic and clinical data were collected and each participant underwent a urinary drug screen. Use/ abuse of cannabis was defined as using cannabis more than 21 times in a single year. Subjects with and without cannabis use/abuse were statistically compared. Results. Significant differences between the two groups were found in terms of gender, marital status, age of onset of schizophrenia, number of hospitalisations and relapses, alcohol abuse, smoking, the Scale for the Assessment of Positive Symptoms (SAPS) scores for hallucinations, delusions, bizarre behaviour and formal thought disorder, and the Scale for the Assessment of Negative Symptoms (SANS) score for avolition/ apathy. Conclusion. The prevalence of cannabis use/abuse in this study was high, and our findings were comparable with those of previous international studies. Abuse/use started mainly in the teenage years, was more prevalent among males than females, and was associated with negative overall outcomes. There was also a positive correlation between cannabis and nicotine and alcohol use/abuse. Determination of cannabis abuse based solely on history was found to be reliable, and urine cannabis testing appeared to be of limited value in routine management of this group of schizophrenic patients.http://sajp.org.za/index.php/sajp/article/view/99Publisher's versio

Using Buy and Rent Discrepancies to Predict Real Estate Bubbles

The cost of housing is one of the biggest recurring expenses Americans face. Real estate is also one of the largest asset classes of investments today. The decision of whether or not it is the right time to purchase a piece of residential real estate can be difficult for the everyday person as well as professionals. With the recent downturn of 2008, many people are reminded that the price of houses can spiral upward, and if one bought at the wrong time, their house could lose a tremendous portion of its value. This study focuses on looking at different economic measures and finding relationships between them and the cost of renting vs buying. The results of this study will hopefully help investors decide if market prices are too high based upon multiple factors
