Effects of urban structure on plant species richness in a large European city

Urban areas have developed under anthropogenic impact and hence feature strongly altered environmental conditions that influence today’s plant species distribution. Generally, urban areas are rich in plant species, but on smaller scales richness can vary considerably. Our study aim is to identify areas of high species richness and to assess richness distribution patterns in the city of Hamburg by analyzing a floristic mapping dataset on the scale of 1 km². Differences in plant species richness were analyzed between three urbanization zones. With multiple regression analyses, we tested effects of urban structure, habitat, and environmental conditions on the distribution of species richness measures. Total species richness per 1 km² was 274?±?60 on average and differed only slightly between the urbanization zones. It increased with habitat diversity and decreased with Ellenberg indicator values (EIV) for nutrients (multiple R²?=?0.31). Proportion of non-native species increased with mean annual temperature and decreased with EIVs for moisture (multiple R²?=?0.72), while proportion of endangered species increased with EIVs for moisture and decreased with EIVs for nutrients (multiple R²?=?0.66). Proportion of thermophilic species (multiple R²?=?0.58) could be explained by mean annual temperature. The emerging patterns probably differ from those in other cities due to the central port harboring a particular flora. Besides the expected high proportions of non-native species, high proportions of endangered species were also found in this area. Our results contribute to identifying drivers of biodiversity in cities and can thus be used to develop measures for the conservation of urban biodiversity.     

Criticising the Solitary Mobile Subject: Researching Relational Mobilities and Reflecting on Mobile Methods

One of the key arguments of the mobilities paradigm is that people’s mobility practices are embedded in their spatial, cultural, political, economical, social and personal context. Yet, empirical mobility research tends to research these two sides of the social separately – either mobility practices and their subjective sense and experience or their discursive, spatial or structural foundation. Taking this desideratum as point of departure, I will make a proposal for researching the links between structures and practices of mobilities consisting of the application of multiple correspondence analysis. This proposal attempts, furthermore, to operationalise mobilities as relational practices, which reinforces that social networks rather than solitary subjects are the origin of mobility decisions. This methodological approach is demonstrated by a comparative data analysis of movement patterns in England and Switzerland. In the final part of the paper, I will reflect upon methods and quantification more generally – against the background of an understanding of mobilities research as being also critical and political.     

Institutional Developments in the Russian System of Social Security: Organizational and Interorganizational Aspects

In the course of the present transition in Russian society, a new system of social security has been developed. The previous Soviet system has been replaced by a system of four more or less independent social funds, covering the main branches of social security. These funds are supposed to be run according to insurance principles and to be financed by contributions, mainly from employers. Given the difficult economic and social situation of the country, there have been increasing demands for effectiveness in the management of the different funds and also in the management of the whole social security system. The results of this study show that the social funds have developed different organizational structures with different degrees of centralization and decentralization. Only one of the funds seems to be relatively well-functioning and effective, while the others have experienced more or less serious problems in fulfilling their main tasks and functions. The most serious problems, however, seem to stem from the structure of the social security system as a whole, which is perceived as fragmented and badly coordinated. In order to improve the coordination of the system, there have been proposals to merge two or more funds into a unified social security organization. This strategy is open to question, however, since it would increase the bureaucracy of the system. There are other ways in which the structure of the social security system might be advanced. Such developments should be based on an analysis of the system from the perspective of the individual client or patient.     

Ubiquitous technologies, cultural logics and paternalism in industrial workplaces

Ubiquitous computing is a new kind of computing where devices enhance everyday artefacts and open up previously inaccessible situations for data capture. ‘Technology paternalism’ has been suggested by Spiekermann and Pallas (Poiesis & Praxis: Int J Technol Assess Ethics Sci 4(1):6–18, 2006) as a concept to gauge the social and ethical impact of these new technologies. In this article we explore this concept in the specific setting of UK road maintenance and construction. Drawing on examples from our qualitative fieldwork we suggest that cultural logics such as those reflected in paternalistic health and safety discourse are central in legitimising the introduction of ubiquitous computing technologies. As such, there is little doubt that paternalism plays an essential role in people’s reasoning about ubiquitous computing in this setting. We argue, however, that since discourses such as health and safety are used by everyone (including both managers and workers) in the organisation to further their own aims, technologies transcend purely paternalistic conceptualisations and instead become a focal point for ongoing struggles for control between those deploying and using them. This means that the benefits and costs of such new technologies become harder to define from an ethical and social perspective.     

Research and development absorptive capacity: a Māori perspective

This paper presents a view of research and development absorptive capacity from a Māori perspective. The assessment is part of a case study of a longitudinal programme – Science for Technological Innovation: Kia kotahi mai – Te Ao Putaiao me te Ao Hanagarau that aims to increase Aotearoa New Zealand’s capacity to use sci-tech for economic benefit. The paper finds that while Aotearoa New Zealand’s macro policy and meso institutional levels have become more responsive to Māori research and development demands, at the micro level of the individual or the firm there are still constraints given the small numbers of Māori in science, technology, engineering and mathematics. In response to this, a novel model of Māori sci-tech capacity is under development that considers not only research and development technical capacities, but also the human and relational capacities required to accelerate absorptive capacity to respond to Māori social and economic aspirations.     

Regime change: gender, class, and the invention of dieting in post-bellum America

"Regime Change" argues against commonly held interpretations that see dieting as a practice established in the 1920s to control women at a time when they gained suffrage and greater economic independence. This article offers an alternative reading, arguing that diet advice literature arrived in the US in the 1860s and originally targeted a male, white, middle-class audience. While the hegemonic beauty ideal for the female body was at its heftiest, men started to build muscle and reduce weight. The ideal of the slender male body was associated with white superiority, social mobility and the national ambition for an American empire. When white middle-class women eventually started dieting in greater numbers in the 1890s, it was because they claimed the same mastery over their bodies as men—and demanded the same privileges as their male peers over immigrants, African Americans and working-class people, who were increasingly imagined as overweight. Revising the history of dieting to show its origins as a masculine practice appropriated by women to stake a claim to class and race privilege invites a rethinking of power and resistance in the disciplining of the female body.     

The Parental Leave Benefit Reform in Germany: Costs and Labour Market Outcomes of Moving towards the Nordic Model

Germany is known to have one of the lowest fertility rates among Western European countries and also relatively low employment rates of mothers with young children. Although these trends have been observed during the last decades, the German public has only recently begun discussing these issues. In order to reverse these trends, the German government recently passed a reform of the parental leave benefit system in line with the model practiced in Nordic countries. The core piece of the reform is the replacement of the existing means-tested parental leave benefit by a wage-dependent benefit for the period of one year. In this paper we simulate fiscal costs and expected labour market outcomes of this reform. Based on a micro-simulation model for Germany we calculate first-round effects, which assume no behavioural changes and second-round effects, where we take labour supply changes into account. Our results show that on average all income groups, couples and single households, benefit from the reform. The calculation of overall costs of the reform shows that the additional costs are moderate. As far as the labour market behaviour of parents is concerned, we find no significant changes of labour market outcomes in the first year after birth. However, in the second year, mothers increase their working hours and labour market participation significantly. Our results suggest that the reform will achieve one of its aims, namely the increase in the labour market participation of mothers with young children.

Power struggles: A sociological approach to activist communication

This paper proposes an alternative approach to the scholarship of activist public relations, based on the ideas of the sociologist Pierre Bourdieu; notably his understanding of activism in society. Although Bourdieu is one of the most quoted sociologists in the world (Santoro, 2011; Truong & Weill, 2012), his work has only received limited attention in public relations, and has been entirely ignored within the context of activist communication. This is despite his focus on power, relationships and the role of activists in modern democracies, all of which are central themes in public relations practice and research. Based on Bourdieu’s theory of practice, the discipline’s prevailing, dominant, industry serving, functionalist paradigm positions public relations’ role in society as to perpetuate social inequalities. However, drawing on his ideas leads us to question if public relations skills could be equally utilized to challenge existing power imbalances in society, either in support or on behalf of those groups and individuals whose voices have been drowned out by traditional public relations efforts. The author argues that Bourdieu was not only an accomplished scholar, but also an activist in his own right. It is this combination of personal experience with academic ideas that lends weight to his scholarly work through which he urged the scholarly community to utilize their skills, knowledge and research to challenge (perceived) inequalities in society. The emergence of this type of activist academic, committed to giving voice to multiple coexisting, sometimes directly competing points of views, would arguably further justify and strengthen the existence of public relations as a scholarly discipline in its own right.
