Chinese Labor Migration to Europe, 2008-16. Implications for China-EU Mobility in the Post-crisis Context

The article examines the evolution of Chinese labour migration to the UK, France, Germany, Netherlands, Spain and Italy in order to elucidate how the flows and stocks of Chinese workers have evolved since the Global Economic Crisis, and what implications this has have for Sino-European mobility partnerships in the post-crisis context. It explains: (1) What comparative data are available on Chinese labour migration to the six principal countries of destination in Europe; (2) How have Chinese labour migration flows and stocks evolved since the GEC; (3) How may the new Chinese workers’ mobility to Europe affect their rights?     

FOREIGN BANKS AND THE BANK LENDING CHANNEL

We provide new evidence on bank ownership and transmission of monetary policy using bank‐level data on 453 banks in Central and Eastern European economies between 1998 and 2012. Only domestic banks adjust loans to changes in monetary policy, while foreign banks do not. Conventional wisdom says that this is because foreign banks can rely on parent banks' funding to insulate against monetary policy shocks. In this paper we document an alternative explanation. Deposits in foreign banks do not react to monetary policy, hence the bank lending channel is only triggered in domestic banks. (JEL E50, F36, G21)     

Development of urban behaviour is associated with time since urbanization in a reed-nesting waterbird

Behavioural adaptations are recognized as crucial determinants for successful establishment and persistence of animal populations in a novel urban environment. Here, we examined mechanisms responsible for the development of urban behavioural type in a common waterbird, the Eurasian coot Fulica atra. We compared the behaviour of coots from a rural population and two urban populations that differed in the timing of colonization event (1960s vs. 2000s). We found that some behavioural characters associated with urban life (aggression during nest defence and boldness towards humans during foraging) were more strongly expressed in the older urban population when compared with the recently established urban population. By contrast, coots from the two urban populations showed a similar likelihood of exploiting human-derived food resources, as well as they showed similar levels of physiological stress. Urban coots were generally more aggressive, bolder, and less stressed than their rural conspecifics. Large behavioural and physiological divergence of coots from the recently established urban population and their rural conspecifics suggested that phenotypic plasticity and phenotype sorting may play a key role in the initial stages of urban colonization. On the other hand, increasing expression of boldness and aggression with the time since urbanization may suggest the role of microevolutionary adaptation in response to novel selective forces associated with the urban environment. Our results indicate that a combination of different processes (phenotypic plasticity, phenotype sorting, and microevolution) can determine successful colonization of urban areas by the Eurasian coots, and possibly other bird species.

Wikipedia in the anti-SOPA protests as a case study of direct,deliberative democracy in cyberspace

This paper contributes to the discussion on deliberative, direct democracy and volunteer mobilization in the Internet era by analyzing the vote participation levels of Wikipedia volunteer editors (Wikipedians). On 18th January 2012 in the ‘first Internet strike’ against the American ‘Stop Online Piracy Act' legislation, over two thousand Wikipedians took part in the vote concerning whether their site should undertake a protest action, with vast majority expressing support for this action. However, the vote participants formed only a tiny fraction of the total number of Wikipedians who number in millions. Although Wikipedia can be seen as an open, democratic forum practicing deliberative, direct democracy, the process of voting on Wikipedia is significantly influenced by participation inequality, with a majority of the vote participation coming from a small group of most active contributors – an effective oligarchy. This paper discusses the intricate dynamics between Wikipedia egalitarian ethos and the creed to discuss project matters deliberately on one hand and the conspicuous lack of promotion and advertisement stemming from a rule against ‘canvassing’ and an overall skepticism regarding the status of majority votes. While voters' passivity and lack of interest play a major role, as expected, another factor emerges as a significant factor responsible for the low levels of participation: an inefficient information distribution system, as the vast majority of Wikipedians were not aware of the ongoing discussions and the vote itself until after their conclusion.     

Time–Threshold Maps: Using information from wavelet reconstructions with all threshold values simultaneously

Wavelets are a commonly used tool in science and technology. Often, their use involves applying a wavelet transform to the data, thresholding the coefficients and applying the inverse transform to obtain an estimate of the desired quantities. In this paper, we argue that it is often possible to gain more insight into the data by producing not just one, but many wavelet reconstructions using a range of threshold values and analysing the resulting object, which we term the Time–Threshold Map (TTM) of the input data. We discuss elementary properties of the TTM, in its “basic” and “derivative” versions, using both Haar and Unbalanced Haar wavelet families. We then show how the TTM can help in solving two statistical problems in the signal + noise model: breakpoint detection, and estimating the longest interval of approximate stationarity. We illustrate both applications with examples involving volatility of financial returns. We also briefly discuss other possible uses of the TTM.     

‘A city is not a company,a flat is not a commodity’: urban movements and defenders of tenants’ rights in Poland

This article describes urban and tenant movements that have been created in Poland in response to the commercialization of urban space and the complete commodification of the right to housing. On the one hand, spatial segregation in Polish cities was fully approved by the state; on the other hand, it became a source of income for new owners of acquired buildings, who often used criminal methods to intimidate tenants. Brutal evictions encountered social resistance from the emerging tenant movement, non-institutionalized left-wing communities and endangered tenants, who were often pensioners and members of the lower classes. The author mentions undertaken and possible methods of social self-defence such as eviction blockades and rent strikes. He also raises the question of whether urban movements can become part of a broader social movement for systemic change.     

Using Dialogic Principles on Websites

This research reports the results of the analysis of public benefit organization (PBO) websites as places for encouraging dialogic relationships with key members of the public. Using a modified Kent and Taylor's (1998) dialogic principle, we conducted a content analysis of 367 PBOs in Poland. The results suggest that analyzed organizations only marginally use the five principles of dialogic communication on their websites. The studies have identified only a few organizations, which have websites characterized as having a high level of dialogic potential. Websites usually contained only some elements, which gave them the appearance of a digital information brochure. In addition, the results indicate that website dialogic potential is significantly influenced by the amount of revenue and the extent of the organization. The higher the revenue and geographic service area, the greater the dialogic potential of websites is as well.     

Employability management practices in the Polish ICT sector

This article examines current career thinking and employability management practices within the Polish Information and Communication Technology (ICT) sector. The aim of this contribution is to identify career management problems and to determine obstacles for implementing employability management practices at a company level. Semi-structured interviews aimed at establishing company needs were conducted with 18 managers of small and medium-sized ICT enterprises in Poland. These firms appear to apply various developmental approaches to stimulate competitive advantage. Faced with a more demanding environment, firms aim for versatility rather than adopting simplified solutions. Managing the careers and employability of ICT professionals is acknowledged as vitally important for the survival and development of ICT companies.     

GOES-8 X-ray sensor variance stabilization using the multiscale data-driven Haar–Fisz transform

Summary.  We consider the stochastic mechanisms behind the data that were collected by the solar X-ray sensor (XRS) on board the GOES-8 satellite. We discover and justify a non-trivial mean–variance relationship within the XRS data. Transforming such data so that their variance is stable and its distribution is taken closer to the Gaussian distribution is the aim of many techniques (e.g. Anscombe and Box–Cox). Recently, new techniques based on the Haar–Fisz transform have been introduced that use a multiscale method to transform and stabilize data with a known mean–variance relationship. In many practical cases, such as the XRS data, the variance of the data can be assumed to increase with the mean, but other characteristics of the distribution are unknown. We introduce a method, the data-driven Haar–Fisz transform, which uses the Haar–Fisz transform but also estimates the mean–variance relationship. For known noise distributions, the data-driven Haar–Fisz transform is shown to be competitive with the fixed Haar–Fisz methods. We show how our data-driven Haar–Fisz transform method denoises the XRS series where other existing methods fail.
