Cooperation and defection in ghetto

We consider ghetto as a community of people ruled against their will by an external power. Members of the community feel that their laws are broken. However, attempts to leave ghetto makes their situation worse. We discuss the relation of the ghetto inhabitants to the ruling power in context of their needs, organized according to the Maslow hierarchy. Decisions how to satisfy successive needs are undertaken in cooperation with or defection the ruling power. This issue allows to construct the tree of decisions and to adopt the pruning technique from the game theory. Dynamics of decisions can be described within the formalism of fundamental equations. The result is that the strategy of defection is stabilized by the estimated payoff.Comment: 12 pages, 2 figure

Personal identity (de)formation among lifestyle travellers: A double-edged sword?

This article explores the personal identity work of lifestyle travellers – individuals for whom extended leisure travel is a preferred lifestyle that they return to repeatedly. Qualitative findings from in-depth semi-structured interviews with lifestyle travellers in northern India and southern Thailand are interpreted in light of theories on identity formation in late modernity that position identity as problematic. It is suggested that extended leisure travel can provide exposure to varied cultural praxes that may contribute to a sense of social saturation. Whilst a minority of the respondents embraced a saturation of personal identity in the subjective formation of a cosmopolitan cultural identity, several of the respondents were paradoxically left with more identity questions than answers as the result of their travels

Implementation of neck/shoulder exercises for pain relief among industrial workers: A randomized controlled trial

BACKGROUND: Although leisure-time physical activity is important for health, adherence to regular exercise is challenging for many adults. The workplace may provide an optimal setting to reach a large proportion of the adult population needing regular physical exercise. This study evaluates the effect of implementing strength training at the workplace on non-specific neck and shoulder pain among industrial workers. METHODS: Cluster-randomized controlled trial involving 537 adults from occupations with high prevalence of neck and shoulder pain (industrial production units). Participants were randomized to 20 weeks of high-intensity strength training for the neck and shoulders three times a week (n = 282) or a control group receiving advice to stay physically active (n = 255). The strength training program followed principles of progressive overload and periodization. The primary outcome was changes in self-reported neck and shoulder pain intensity (scale 0-9). RESULTS: 85% of the participants followed the strength training program on a weekly basis. In the training group compared with the control group, neck pain intensity decreased significantly (-0.6, 95% CI -1.0 to -0.1) and shoulder pain intensity tended to decrease (-0.2, 95% CI -0.5 to 0.1, P = 0.07). For pain-cases at baseline (pain intensity > = 3) the odds ratio - in the training group compared with the control group - for being a non-case at follow-up (pain intensity < 3) was 2.0 (95% CI 1.0 to 4.2) for the neck and 3.9 (95% CI 1.7 to 9.4) for the shoulders. CONCLUSION: High-intensity strength training relying on principles of progressive overload can be successfully implemented at industrial workplaces, and results in significant reductions of neck and shoulder pain.

‘Our newsroom in the cloud’: Slack, virtual newsrooms and journalistic practice

Virtual newsrooms have enormous potential: enabling journalists around the world to pool their knowledge, skills and perspectives within joint projects, such as the Panama Papers. These virtual newsrooms are supported by Online Collaborative Software (OCS), the most popular of which is Slack. But although many of the world’s top news organisations now use Slack, there is no empirical research examining its impact on workplace processes or culture. This article presents the results of a year-long ethnographic study of a global digital news outlet, whose remote journalists collaborate, almost exclusively, via Slack. We found that the platform deepened relationships and enabled new creative practices across geographic regions. However, it also contributed to the erasure of the line between private and professional spheres for workers, and introduced new opportunities for management to shape newsroom culture. We argue that the concept of ‘space’ as developed by Harvey can helpfully frame the analysis of these new, important digital platforms

Between Choice and Stigma:Identifications of Economically Successful Migrants

In this contribution, we draw on the unusual but interesting comparison between ‘immigrants’ and ‘expats’, with the aim of scrutinizing identity construction and the tensions between stigma and identity of choice against the background of the (reluctant) superdiverse city of Rotterdam. We focus on two types of socioeconomically successful migrants which, despite their similarities in class position, are generally regarded as rather different. First, middle-class migrants and members of the second generation from ‘classic’ migration groups in the Netherlands (with roots in Surinam, Turkey and Morocco, including descendants of former guest workers). Second, expatriates or knowledge workers of various national backgrounds (including American, English, Indian, Chinese) who came to the Netherlands on a temporary basis because of their highly-skilled jobs (or the jobs of their partners, as we also included trailing spouses). We address the questions of how these migrants perceive themselves, how they think that others perceive them, and how discrepancies between these two affect their feelings of belonging in the city of Rotterdam and the Netherlands. Our findings suggest that while both ‘immigrants’ and ‘expatriates’ combine various identities, immigrants have more difficulty to adopt alternative identities (such as ‘cosmopolitan’) than expatriates because of their dominant label as ‘allochtoon’ (non-native Dutch).</p

Cerebral blood flow characteristics in patients with post-lumbar puncture headache

The aim of this study was to verify if diagnostic lumbar puncture (DLP) in post-lumbar puncture headache (PLPH) patients is related to significant changes in cerebral blood flow which could be visualized by transcranial Doppler (TCD). Sixty-six patients were enrolled in this study. TCD was performed 24 h before DLP and repeated within 24 h after the procedure. The measurements included mean velocity (Vmean), peak systolic velocity (Vmax), and Gosling’s pulsatility index (PI), in the left and right middle cerebral artery (MCA). PLPH was observed in 21 patients (32%). No significant differences were noted in Vmean, Vmax and PI between the right and left MCAs—both before DLP and following this procedure. In patients who developed PLPH, bilateral pre-puncture values of Vmean and Vmax were significantly higher and PI was significantly lower compared to unaffected individuals. No significant differences were observed between these groups in terms of post-puncture Vmean and Vmax, but the post-puncture PI was still significantly lower in PLPH cases. In PLPH cases, the post-puncture values of Vmean and Vmax were significantly lower than the respective baseline parameters. A significant inverse correlation was present between PLPH severity and bilateral pre-puncture PI. In conclusion, this study revealed that higher baseline values of Vmean and Vmax and low PI in bilateral MCAs predispose patients to PLPH

Africa in the click stream: audience metrics and foreign correspondents in africa

Digital technologies have transformed the relationship between news outlets, journalists and their audiences. Notably, editors can now monitor their websites and discern the exact news preferences of their readers. Research suggests that some editors are using this data to help them produce more popular, ‘click friendly’ content. To date, research on this phenomenon has focused on journalists working within newsrooms. This article adds to the literature by exploring the relationship of foreign correspondents in Africa with their audiences, and asks whether readership metrics are influencing the journalists’ selection and development of news stories. Drawing on 67 interviews with foreign correspondents in East and West Africa, the article identifies three different approaches to audience metrics: correspondents who are 1) data-driven; 2) data informed; and 3) data denialists. The article discusses the implications of these approaches for the media image of Africa that is distributed around the globe
