Piercing the surface: A mechanical analysis of stabbing with household tools

Estimating the applied power during a stabbing incident, or estimating the minimal force necessary to penetrate the body with a certain weapon is a challenging task in forensic practice. A thorough forensic evaluation of stabbing forces needs objective numerical experimental data. Stabbing tests of 12 different weapons – including knives, a pair of scissors, a fork, screwdrivers, a rasp, a corkscrew, and a utility knife blade – were performed with a Mecmesin MultiTest-dV material tester on pork loin and ballistic gel to estimate the stabbing forces and dynamics. Penetration force (F_p) and maximal force (F_max) were recorded, and the registered force curves were analyzed. F_max was 159.8–212.07 Newton (N), 30.56–30.58 N, 168.9–185.48 N for various knives; 171.39–190.43 N for the pair of scissors, 233.6 N for the fork; 532.65–562.65 N, 370.31–367.19 N and 314.51–432.89 N for various screwdrivers, 44.14–56.62 N for utility knife during pork loin stabbing. The butter knife, corkscrew and rasp were not able to penetrate the pork loin, and the curved fork bent during stabbing. The results prove that weapon characteristics greatly influence the force necessary for penetration. Maximal stabbing force depends mostly on tip sharpness, and the force sharply decreases after penetration occurs, which indicates that edge sharpness is not as important as tip characteristics during stabbing perpendicular to skin surface. The penetration force during stabbing with a pair of scissors is comparable to the penetration force of knives. Stabbing with screwdrivers generally needs larger force than average knives but depends greatly on screwdriver size.     

Institutionelle Arbeit am Konflikt – ein Beitrag zur Transnationalisierung der Arbeitsbeziehungen?

Although political decisions and the mobility of capital have advanced the integration of markets at the European and the global level, durable transnational bargaining relationships between labor and capital remain rare. Drawing on case studies in two automobile companies the article explores whether and how class-based conflicts are institutionalized in the transnational social space of European industry. Concepts are borrowed from the theories of Pierre Bourdieu and neo-institutionalism to develop a relational, space-sensitive understanding of power lacking in existing perspectives, such as the power resource approach. This allows for a better grasp of the institutions shaping transnational employment relations in the two studied companies, Volkswagen and General Motors-Opel, as well as of the differing stability of these institutions.     

An Ever-Shadowed Past? Citizens’ Attitudes towards the Dictatorship in Twenty-First Century Portugal

Abstract

Several years after the transition to democracy, positive attitudes towards the authoritarian past are still observable in Portugal: the belief that the previous regime had more good things than bad things is expressed by about one-fifth of the Portuguese. What explains this nostalgic sentiment? Are factors such as socialisation under the regime, party identification or religiosity more important than satisfaction with democracy and the state of the economy? The empirical analysis suggests that the relevance of these factors varies considerably, but socialisation phases lead to different stances on the past both in routine times and in times of economic crisis.     

Portuguese Democratisation 40 Years on: Its Meaning and Enduring Legacies

Abstract

On the fortieth anniversary of the Carnation Revolution, it is pertinent to ask how Portuguese citizens understand their transition to democracy. In this article, some of the main findings concerning the meanings and legacies of 25 April 1974 are presented, drawing on the findings of two surveys focusing on Portuguese attitudes towards 25 April and fielded in 2004 and 2014, respectively, to a representative sample of the Portuguese population. Here we focus on the degree to which the transition is viewed positively and its social and economic legacies. In the final sections, the main findings of the articles in this special issue are discussed through a presentation of the main questions they answer and the new ones they raise.     

Ethnographic filmmaking as narrative capital enhancement among Atauro diverwomen: a theoretical exploration

This article reports on a project involving the development and release of an ethnographic film about the women divers of Atauro Island, Timor-Leste, and suggests a theoretical framework to interpret its outcomes. It describes the project aims and the filmmaking process, and reports on its results. In doing so, the paper explores the potential use of an agent-based concept of narrative capital focused on collective agents. The article suggests that the ideas of narrative capital and transformations of capital by collective agents can provide a valuable interpretative framework for the design, implementation, and analyses of results of development interventions involving filmmaking.     

European perspectives towards the rise of Asia: contextualising the debate

To what extent can we speak of a distinctively ‘European’ security approach towards the Asia-Pacific region? In order to address that timely question, this article examines how Britain, France, Germany and the European Union (EU) are framing their evolving security roles in the Asia-Pacific region, and how those individual perspectives intersect with each other. The article identifies a number of important common features in Europe’s approaches towards security in the Asia-Pacific, namely the tendency of most European actors to emphasize the economic and diplomatic nature of their contribution to regional security, their promotion of regional multilateral security fora, their rejection of the notion that China’s rise is inherently challenging for regional and global security, and their willingness to signal their differences towards Washington’s emphasis on military power and alliance-based approach. However, and despite the existence of common traits, individual European actors show different degrees of closeness vis-à-vis the US and China and feature different perspectives regarding which security relationships they should prioritize in the region (if any), or the appropriate balance between diplomacy and security and defence cooperation. Such divergences prevent Europeans from developing a coherent security profile in the region and preclude us from speaking of a distinctively European security approach towards the Asia-Pacific.     

Partner Violence Entrapment Scale: Development and Psychometric Testing

This article describes the development and testing of the psychometric properties of the Partner Violence Entrapment Scale (PVES), an instrument that evaluates the women’s perceived reasons for staying in violent partner relationships. After initial pilot testing, the scale was administered to 213 Spanish women who were victims of intimate partner violence (IPV). An exploratory factor analysis identified six factors: Socio-Economic Problems, Attachment and Fear of Loneliness, Blaming Oneself and Resignation, Impact on Children, Fear of Harm and Worry for the Partner, and Feelings of Confusion. Discriminant validity was established by demonstrating associations between PVES factors and socio-demographic, clinical and abuse variables. The scale appears to be a useful assessment tool for social and clinical settings. Its factor structure, reliability, and validity need to be replicated in other populations and samples.     

Country level efficiency and national systems of entrepreneurship: a data envelopment analysis approach

This paper tests the efficiency hypothesis of the knowledge spillover theory of entrepreneurship. Using a comprehensive database for 63 countries for 2012, we employ data envelopment analysis to directly test how countries capitalize on their available entrepreneurial resources. Results support the efficiency hypothesis of knowledge spillover entrepreneurship. We find that innovation-driven economies make a more efficient use of their resources, and that the accumulation of market potential by existing incumbent businesses explains country-level inefficiency. Regardless of the stage of development, knowledge formation is a response to market opportunities and a healthy national system of entrepreneurship is associated with knowledge spillovers that are a prerequisite for higher levels of efficiency. Public policies promoting economic growth should consider national systems of entrepreneurship as a critical priority, so that entrepreneurs can effectively allocate resources in the economy.     

Growth and the Welfare State in the EU: A Causality Analysis

In this paper, we test for causality between GDP growth andsocial protection expenditure in the European Union. To that end,we apply Hsiao's (1981) sequential procedure to data for twelveEU countries along the 1970–1994 period. Our results suggestthat, for Belgium, Germany, Ireland, Luxembourg, the Netherlands,Portugal, and Spain, causality runs only from social protectiongrowth to GDP growth, while for Denmark, France, Greece, Italy,and the United Kingdom, no causality is found between socialprotection growth and GDP growth.
