Workload control: Successful implementation taking a contingency-based view of production planning & control
Full text linkPurpose – The purpose of this paper is to present a successful implementation of a comprehensive workload control (WLC) concept; and to describe the associated implementation process. Design/methodology/approach – Longitudinal action research using a contingency-based approach to ensure alignment between the case company and the characteristics of the WLC approach; and the resulting expected improvements in performance. A set of 17 issues and responses from the literature is used as a checklist for implementing WLC. Findings – Performance improvements include: reduced lead times; significant improvement in lateness and tardiness; reduced costs; improved internal and external co-ordination; and higher quality. The relevance of 15 of the 17 implementation issues is confirmed along with the same response as in previous research for ten issues and an improved response for five issues. In addition, three new issues are identified and addressed. Research limitations/implications – Dependability was a more important competitive priority in this company than speed; and, therefore, the ability of WLC to reduce lead times was not fully assessed. Practical implications – The importance of a contingency-based approach to production planning and control is confirmed. Comprehensive WLC approaches are closely aligned with the high-variety/low-volume context of make-to-order (MTO) companies. Originality/value – This is the first paper that empirically demonstrates performance improvements resulting from WLC alongside a detailed discussion of the implementation process. Few examples of successful implementations have been published previously, and these tend to treat the implementation process as a “black box”. Where more detail on the implementation process has been given in previous studies, evidence of effectiveness in practice was not provided
Trauma Scoring systems
No full textNumerous trauma scoring systems have been developed over the last forty years to describe injury severity and predict the probability of survival and, to a lesser extent, the degree of residual impairment that may result from such injuries. The important features of trauma scoring systems are utility (how useful is the scroing system?), validity (does the scoring system measure what it purports to measure?), reliability (is the information collected reproducible under identical circumstances?) and discriminating capacity (how sensitive is the scoring system at detecting differences?)
Behaviour Change Programs

By application of the scientific disciplines to the problem of injury, we can achieve solutions to this public health problem. This is a guide to injury prevention and control.

Injury Classification Systems
No full textClassifications allow us to reduce the comlexities of qualitative information to standardised codes and enable the collection, storage and analysis of comparable injury data. The process of applying a classification in accordance with its associated rules and conventions is known as coding. This chapter will focus on the injury event and its cause, data capture and coding issues, and the strengths and limitations of coding systems
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
The development and application of an interactive end-user training tool: part of an implementation strategy for workload control
Full text linkWorkload control (WLC) is a production planning and control (PPC) concept designed for complex manufacturing environments, with particular relevance to make-to-order (MTO) companies and small and medium sized enterprises (SMEs). Despite receiving much attention in the literature, few successful implementations have been reported. Moreover, a lack of awareness regarding WLC in industry affects the support it receives from employees within a company and, if implemented, it is sometimes misused or neglected. This article presents a new interactive WLC training and implementation tool developed within a WLC decision support system (DSS) which uses simulation to generate the incoming order stream at the customer enquiry and job entry stages and to mirror the throughput time variability on the shop floor of real-life manufacturing environments. This provides an action-learning package for end-users in order to improve understanding of the concept and generate support prior to implementation. In particular, the tool provides training and decision-making experience in: parameter setting; due date setting; the acceptance/rejection of jobs; scheduling intervention; order release decisions; and capacity management. This article reports on the application of the tool as part of a strategy to implement WLC in a small subcontract MTO company. Among other results, use of the tool: improved understanding of WLC; highlighted gaps between current business processes and those supported by WLC; and led to rethinking the choice of end-user for the DSS
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
