Introduction: The aim of this review was to gain an understanding of the first 20 years of contributions to WORK within the assessment domain and to reflect on the perspectives underscoring this knowledge base.
Method: A narrative review of assessment articles using the WORK ARTicle database was conducted. Assessment articles were searched using issues from 1990 to 2009. Descriptive data was analyzed to examine historical trends of the specific types and dimensions of articles, the regional location of the contributions, and the methodological accordance. A reflective process was used by an editorial board member of WORK to inductively interpret perspectives and contextual issues that underpinned the evolution of the assessment domain in WORK.
Results: Over half of N= 108 of the articles on assessment in WORK focused on establishing or reporting reliability and validity of assessments used in clinical practice or evaluation research. The majority of the assessment articles were predominantly focused on the person. Contributions of articles were from 5 regions: North America, Europe, Australia, Asia and Africa.
Conclusions: Assessment articles in WORK have contributed to the development of evidence to support assessment of the worker. These articles represent a knowledge base that emphasizes evidence-based assessments to evaluate what a person can and cannot do to participate in work. Efforts are needed to expand knowledge generation in assessment to include more evaluations on the workplace and occupation dimensions, and that also considers the worker in context.
Sollen Klassenräume über Fenster belüftet werden, kann dies über Stoßlüftung oder genau dosierte Dauerlüftung erfolgen. Messungen verschiedener Institutionen zeigen, dass die erforderliche regelmäßige Stoßlüftung in Schulen nicht praktiziert wird.
Damit eine Dauerlüftung aber funktionieren kann, muss ermittelt werden, welcher Fenstertyp bei welcher Öffnungsweite bei behaglichen thermischen Verhältnissen im Raum den notwendigen Luftwechsel gewährleistet. Deshalb wurden an einem Freilandversuchsstand des Fraunhofer‐Instituts für Bauphysik Schwingflügel und Kippflügel auf ihre Eignung zur Dauerlüftung in Klassenräumen untersucht.
Da sich bei den vielen Einflussfaktoren auf die freie Lüftung die deskriptive Analyse oft als sehr schwierig erweist, wird ein besonderes statistisches Verfahren, ein Entscheidungsbaumverfahren verwendet, das sowohl hinsichtlich der Auswahl der Einflussgrößen und der Modellüberanpassung sehr günstige statistischmethodische Eigenschaften besitzt.
Mit diesem Verfahren können Einflussgrößen mit unterschiedlichen Skalenniveaus adäquat in die Auswertung einbezogen werden. Dabei erhält man ein intuitiv interpretierbares Regelwerk, welches dem Anwender einen erklärenden Einblick in die Zusammenhangsstruktur des untersuchten Prozesses liefert.
The work reported in this thesis addresses the problem of structure-borne sound transmission in buildings. Vibrating sources, such as services plant and domestic appliances, transmit vibro-acoustic power, causing noise complaints by occupants in rooms removed from the source room. There is not yet an accepted practical method of predicting the installed power into floors or supporting walls, and thence the resultant sound pressure in rooms.
This study concentrates on the prediction of the installed power from mechanical installations in lightweight buildings composed of framed and ribbed plates. To identify the characteristics of such receiver elements, a field survey has been undertaken, which involved measurement of the point and transfer mobilities of common wall and floor structures. It is shown that the range of measured values of receiver point mobility is surprisingly small and that the constructions investigated often displayed thin plate-like characteristics, with relatively small spatial variations in point mobility. These field measurements give support to the notion of averaging over contacts.
This single equivalent receiver mobility has been assembled both from measured data and from the approximate method and then used in combination with single equivalent source data, to yield an approximate prediction of the installed power. The agreement obtained between the exact and approximate values allowed consideration of a practical implementation of the approximate prediction method, based on a reception plate method which yields the activity and mobility of the tested machine as single equivalent values.
Manufacturing-Execution-Systeme (MES) werden in der Fertigungsindustrie dazu eingesetzt, einen durchgehenden Informationsfluss zwischen den an der Fertigung beteiligten Systemen herzustellen. Von der Vernetzung aller an der Produktion beteiligten Systeme wird dabei eine gesteigerte Produktivität auf Shop-Floor-Ebene erwartet. Beim Durchlauf des beispielhaft gezeigten Fertigungsauftrages wurden durch den Einsatz von MR-CM©, einem von der Maschinen-fabrik Reinhausen entwickelten und implemen-tierten MES, bereits einige Produktivitätspotenziale im Vergleich mit der konventionellen Abwicklung ohne Einsatz des MES deutlich. Diese resultieren im Wesentlichen aus der Eliminierung von nicht wertschöpfenden Schnittstellenproblemen zwischen den an der Auftragsdurchführung beteiligten Maschinen. Die erzielten Produktivitätszuwächse bestehen im Kern aus einer Verkürzung der Maschinenrüstzeiten, was zu einer Reduktion der Produktionskosten und einer Zunahme der Produktionsflexibilität führt und zu einer Reduzierung der Werkzeugbestände sowie der damit verbundenen Kapitalbindungskosten.
Objectives: A historical review of the editorial board and the founding editor of WORK: A Journal of Prevention, Assessment and Rehabilitation was conducted to examine the understanding of the editorship and contributions of this team to the knowledge in WORK.
Participants: The team of four authors worked together to identify an approach to evaluate the contributions and impact of WORK's editorial board (EB) on the journal's scholarship. The editor-in-chief (EIC) and editorial board members were participants in this evaluation.
Methods: Informative and formative evaluations were used to investigate how knowledge was shaped through the development of an epistemic community of scholars in the field of work. Metrics of the EB composition and participation in the journal as well as surveys and interviews with the board and the editor-in-chief were analyzed.
Results: The EB represents an international community of scholars with a common interest in work and who contribute academically both within WORK and beyond. The epistemic community that has evolved through the editorial board represents a pluralistic perspective on work that is needed to inform practice, and knowledge.
Conclusion: Future directions to continue to advance knowledge through WORK's editorial board and EIC are elaborated.
In listwise directed forgetting, participants are cued to forget previously studied material and to learn new material instead. Such cueing typically leads to forgetting of the first set of material and to memory enhancement of the second. The present study examined the role of working memory capacity in adults' and children's listwise directed forgetting. Working memory capacity was assessed with complex span tasks. In Experiment 1 working memory capacity predicted young adults' directed-forgetting performance, demonstrating a positive relationship between working memory capacity and each of the two directed-forgetting effects. In Experiment 2 we replicated the finding with a sample of first and a sample of fourth-grade children, and additionally showed that working memory capacity can account for age-related increases in directed-forgetting efficiency between the two age groups. Following the view that directed forgetting is mediated by inhibition of the first encoded list, the results support the proposal of a close link between working memory capacity and inhibitory function.
