Influence of stakeholder communication on consensus making in requirements negotiation

Consensus building is essential in aligning multiple stakeholder viewpoints which are commonly emerging during the process of requirements elicitation, analysis and validation [15]. In fact, agreement among diverse groups of stakeholders is deemed prerequisite to establishing project cooperation and collaboration. While individuals frequently rank the importance of their personal goals over the goals of an organisation, having an appropriate strategy for finding common ground among individuals is crucial to any project's success. This paper therefore explores factors that influence the consensus making process and develops a model that helps with understanding the role of consensus specifically during the elicitation phase of the Requirements Engineering process.

Book review : Citizen voices: performing public participation in science and environment communication

In Citizen Voices Phillips, Carvalho and Doyle present a collection of articles exploring the meaning of “citizens” and their role as initiators of communication on science and as actors in formal public engagement exercises involved in science governance. Focusing on the dialogic process, the articles provide empirical insight into the effect of citizen voices on participatory decision-making and a range of related theories and methodologies.

Indonesian masculinities : images of men in Indonesian TV advertising

This article examines images of men in Indonesian popular culture, focussing on TV advertising in particular.  Extending previous feminist scholarship on gendered representations in the Indonesian media, this article suggests that on the surface, Indonesian TV commercials reinforce and streobrthen male dominance in Indonesian society, promoting the notion that a man's primary roles are public ones, and a woman's primary roles are domestic ones. However, this investigation also suggests that so-called 'domesticated' women are also represented as actors in the public sphere, in roles as earners and spenders. This observation correlates with the argument that from the late New Order period, in media representation - and in some small sections of society, even in practice - women and men in Indonesia were becoming increasingly more equal (Sen, 1994, 2002). But is the pendulum of gender relations now swinging the other way? By examining Indonesian popular culture from the perspective of what it reveals about men and masculinity, this paper argues that a significant number of TV commercials may point towards another emergent trend in contemporary Indonesian popular culture: the rise of misandry, which is defined as a negative or contemptuous attitude towards men, 'the sexist counterpart of misogyny' (Nathanson and Young 2001, ix).

Effects of tv time and other sedentary pursuits

Television (TV) viewing is the dominant recreational pastime at all ages, especially for children and adolescents. Many studies have shown that higher TV viewing hours are associated with higher body mass index (BMI), lower levels of fitness and higher blood cholesterol levels. Although the effect size estimated from observational studies is small (with TV viewing explaining very little of the variance in BMI), the results of intervention studies show large effect sizes. The potential mediators of the effect of higher TV viewing on higher BMI include less time for physical activity, reduced resting metabolic rate (for which there is little supporting evidence) and increased energy intake (from more eating while watching TV and a greater exposure to marketing of energy dense foods). Electronic games may have an effect on unhealthy weight gain, but are less related to increased energy intake and their usage is relatively new, making effect size difficult to determine. Thus, TV viewing does not explain much of the differences in body size between individuals or the rise in obesity over time, perhaps because of the uniformly high, but relatively stable, TV viewing hours. Reducing TV viewing hours is a difficult prospect because potential actions, such as social marketing and education, are likely to be relatively weak interventions, although the evidence would suggest that, if viewing could be reduced, it could have a significant impact on reducing obesity prevalence. Regulations to reduce the heavy marketing of energy dense foods and beverages on TV may be the most effective public health measure available to minimize the impact of TV viewing on unhealthy weight gain.

The animation of psychology

This thesis investigates 'Frankenstein', in the light of Cultural Poetic practices and modern psychological theories, illustrating the pivotal role it played in the transition of developmental psychology from philosophy to science. Drawing on Locke, Rousseau and Godwin, Shelley presents the monster as an exaggerated case study of the danger of ineffective nurturing.

Study on the antibacterial properties of superfine wool powder part I : experiment

The superfine wool-powder was prepared by ball and jet milling. According to FZ/T 01021-92 method the bacteriostatic property of the wool-powder was tested. The results showed that wool-powder had excellent antibacterial activity against Escherichia coli (E. coli) and Staphylococcus (MRSA), and the antibacterial rate of E. coli could reach 85% and the MRSA could exceed 70%. The IR spectroscopy and X-ray diffraction analysis were used to discuss the antibacterial properties of superfine wool-powder.

Incorporating domain knowledge with video and voice data analysis in news broadcasts

This paper addresses the area of video annotation, indexing and retrieval, and shows how a set of tools can be employed, along with domain knowledge, to detect narrative structure in broadcast news. The initial structure is detected using low-level audio visual processing in conjunction with domain knowledge. Higher level processing may then utilize the initial structure detected to direct processing to improve and extend the initial classification.

The structure detected breaks a news broadcast into segments, each of which contains a single topic of discussion. Further the segments are labeled as a) anchor person or reporter, b) footage with a voice over or c) sound bite. This labeling may be used to provide a summary, for example by presenting a thumbnail for each reporter present in a section of the video. The inclusion of domain knowledge in computation allows more directed application of high level processing, giving much greater efficiency of effort expended. This allows valid deductions to be made about structure and semantics of the contents of a news video stream, as demonstrated by our experiments on CNN news broadcasts.

Real science and school science : endless wonder versus the drive to explore

Science may be simply defined as a way of finding out about how the world works. It is often viewed as objective and being built on a step-wise procedural base. The question arises as to whether school science needs to be different to cutting-edge (‘real’) science since the outcomes have different purposes, one requiring scientific breakthroughs, the other being imitative and simple. The divergence between these two realities of science impacts on the development of science curricula in that relevance for students, rather than purely imitating real science, steers science curricula.

Persistence on therapy and propensity matched outcome comparison of two subcutaneous interferon beta 1a dosages for multiple sclerosis

To compare treatment persistence between two dosages of interferon β-1a in a large observational multiple sclerosis registry and assess disease outcomes of first line MS treatment at these dosages using propensity scoring to adjust for baseline imbalance in disease characteristics. Treatment discontinuations were evaluated in all patients within the MSBase registry who commenced interferon β-1a SC thrice weekly (n = 4678). Furthermore, we assessed 2-year clinical outcomes in 1220 patients treated with interferon β-1a in either dosage (22 µg or 44 µg) as their first disease modifying agent, matched on propensity score calculated from pre-treatment demographic and clinical variables. A subgroup analysis was performed on 456 matched patients who also had baseline MRI variables recorded. Overall, 4054 treatment discontinuations were recorded in 3059 patients. The patients receiving the lower interferon dosage were more likely to discontinue treatment than those with the higher dosage (25% vs. 20% annual probability of discontinuation, respectively). This was seen in discontinuations with reasons recorded as “lack of efficacy” (3.3% vs. 1.7%), “scheduled stop” (2.2% vs. 1.3%) or without the reason recorded (16.7% vs. 13.3% annual discontinuation rate, 22 µg vs. 44 µg dosage, respectively). Propensity score was determined by treating centre and disability (score without MRI parameters) or centre, sex and number of contrast-enhancing lesions (score including MRI parameters). No differences in clinical outcomes at two years (relapse rate, time relapse-free and disability) were observed between the matched patients treated with either of the interferon dosages. Treatment discontinuations were more common in interferon β-1a 22 µg SC thrice weekly. However, 2-year clinical outcomes did not differ between patients receiving the different dosages, thus replicating in a registry dataset derived from “real-world” database the results of the pivotal randomised trial. Propensity score matching effectively minimised baseline covariate imbalance between two directly compared sub-populations from a large observational registry.
