    Purpose While the static and dynamic lung volumes of active swimmers is often greater than the predicted volume of similarly active non-swimmers, little is known if their ventilatory response to exercise is also different. Methods Three groups of anthropometrically matched male adults were recruited, daily active swimmers (n = 15), daily active in fields sport (Rugby and Football) (n = 15), and recreationally active (n = 15). Forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), and maximal voluntary ventilation (MVV) was measured before and after exercise to volitional exhaustion. Results Swimmers had significantly larger FVC (6.2 ± 0.6 l, 109 ± 9% pred) than the other groups (5.6 ± 0.5 l, 106 ± 13% pred, 5.5 ± 0.8, 99% pred, the sportsmen and recreational groups, respectively). FEV1 and MVV were not different. While at peak exercise, all groups reached their ventilatory reserve (around 20%), the swimmers had a greater minute ventilation rate than the recreational group (146 ± 19 vs 120 ± 87 l/min), delivering this volume by breathing deeper and slower. Conclusions The swimmers utilised their larger static volumes (FVC) differently during exercise by meeting their ventilation volume through long and deep breaths

    Exploring the cultural dimensions of environmental victimization

    It has become increasingly clear in recent years that our understanding of ‘victimisation’ is informed by a whole range of societal and political factors which extend well beyond whatever particular form of words appears in any given directive, code or legislative instrument concerning crime, crime victims or criminal justice systems. In this paper, I will seek for the first time to apply recent developments in our understanding of so-called 'cultural victimology' to the issue of environmental harm and its impact on human and non-human animals. McCGarry and Waklate (2015) characterise cultural victimology as broadly comprising of two key aspects. These are the wider sharing and reflection of individual and collective victimisation experiences on the one hand and, on the other, the mapping of those experiences through the criminal justice process. In this discussion I will examine how environmental victimisation is viewed by and presented to society at large and will argue that such representations often fail, as a form of testimony, to adequately convey the traumas involved. Nor is this achieved through the application of present models of criminal, civil or administrative justice regimes in many jurisdictions. This lack of cultural acknowledgement of the harms vested on environmental victims, it is argued, afford us a clearer understand of the continued reticence amongst lawmakers, politicians and legal practitioners to adequately address the impacts of such victimisation through effective justice or regulatory mechanisms. This is unfortunate given that the often collective nature of environmental victimisation makes this particularly suited to a more cultural analysis and understanding. It is argued that various forms of environmental mediation processes might hold the key to this cultural reticence to accept environmental harm as a 'real' and pressing problem as compared to other criminal and civil justice concerns

    Drivers for international innovation activities in developed and emerging countries

    This paper aims to shed light on firm specific drivers that lead firms to internationalise their innovation activities. The paper draws a comprehensive picture of driving forces by including firm capabilities, characteristics of the firm’s competitive environment and the influence of innovation obstacles in the home country. In particular, the role of the potential driving forces is tested on the probability to carry out different innovative activities abroad (R&D, design/conception of new products, manufacturing of innovative products and implementation of new processes). In a second step these driving forces are used to observe their impact on the decision to locate innovation activities in various countries and regions (China, Eastern Europe, Western Europe and North America) as well as in groups of countries with similar levels of knowledge (country clubs). The analysis is based on the Mannheim Innovation Panel survey which represents the German CIS (Community Innovation Survey) contribution. Two survey waves are combined and result in a sample of about 1400 firms. The results show that the decision to perform innovation activities abroad is mainly driven by organisational capabilities such as absorptive capacities, international experience and existing technological competences of the respective firm. Innovation barriers at the German home base such as lack of labour and high innovation costs foster the set up of later-stage innovation activities abroad while the lack of demand demonstrates a barrier to the internationalisation decision for the development and manufacturing of new products. Location decisions receive the strongest influencing effects from the international experience of the firm. Firms which innovate in developing countries seem to require a more extensive level of international experience by international R&D cooperation

    Beyond crime statistics: the construction and application of a criminogenity monitor in Amsterdam

    Get PDF
    Criminologists have devoted a great deal of attention to risk factors - also called criminogenic factors - leading to criminal offending. This paper presents a criminogenity monitor which includes 19 risk factors that underlie crime. These factors do not themselves cause criminal behaviour; rather, they must be seen as signals that crimes may be committed. After discussing how the criminogenity monitor was constructed, we apply the risk factors we examined to the situation in Amsterdam, capital city of the Netherlands. The monitor is intended to function particularly as an instrument to rationalise policy-makers' work in targeting and preventing symptoms of crime at three geographical levels: the entire city, its boroughs and its neighbourhoods. © 2012 The Author(s)

    Drivers and Effects of Internationalising Innovation by SMEs

    Get PDF
    This paper investigates the drivers and the effects of the internationalisation of innovation activities in SMEs based on a large data set of German firms covering the period 2002-2007. We look at different stages of the innovation process (R&D, design, production and sales of new products, and implementation of new processes) and explore the role of internal resources, home market competition and innovationrelated location advantages for an SME’s decision to engage in innovation activities abroad. By linking international innovation activities to firm growth in the home market we try to identify likely internationalisation effects at the firm level. The results show that export experience and experience in knowledge protection are highly important for international innovation activities of SMEs. Fierce home market competition turns out to be rather an obstacle than a driver. High innovation costs stimulate internationalisation of non-R&D innovation activities, and shortage of qualified labour expels production of new products. R&D activities abroad and exports of new products spur firm growth in the home market while there are no negative effects on home market growth from shifting production of new products abroad

    Safety vs. reputation: risk controversies in emerging policy networks regarding school safety in the Netherlands

    Get PDF
    This article deals with risk controversies in emerging policy networks regarding school safety in the Netherlands. It offers a grounded account of the interpretations of school risks and safety measures by the various stakeholders of the policy network, in particular, schools, local government and the police. Theoretically, policy networks are conceived as mediating between the structural conditions of the risk-society and the culture of fear on the one hand and the institution of safety standards on the organizational level of schools on the other hand. It is argued that in the low-risk context of schools, it is particularly important to take into account the soft, cultural side of safety next to the hard, material side of safety. This distinction also accounts for the ambiguities and controversies over school risks. A further conclusion is that in this network a lack of local leadership seems to hinder the development of firm safety measures. Overall, this article highlights the paradox between a concern for safety and a concern for a schools reputation. © 2012 Taylor & Francis
