Fuelling traffic : abolitionist claims of a causal nexus between legalised prostitution and trafficking

Over the last decade, researchers and legislators have struggled to get an accurate picture of the scale and nature of the problem of human trafficking. In the absence of reliable data, some anti-prostitution activists have asserted that a causal relationship exists between legalised prostitution and human trafficking. They claim that systems of legalised or decriminalised prostitution lead to increases in trafficking into the sex industry. This paper critically analyses attempts to substantiate this claim during the development of anti-trafficking policy in Australia and the United States. These attempts are explored within the context of persistent challenges in measuring the scale and nature of human trafficking. The efforts of abolitionist campaigners to use statistical evidence and logical argumentation are analysed, with a specific focus on the characterisation of demand for sexual services and systems of legalised prostitution as ‘pull’ factors fuelling an increase in sex trafficking. The extent to which policymakers sought to introduce evidence-based policy is also explored.

A Teoria da assunção do risco e a prática esportiva, análise à luz do direito civil-constitucional.

O presente trabalho analisa a teoria da assunção do risco, que se originou no Direito francês com influência do commow Law, aplicável na atividade desportiva à luz dos princípios e valores do Direito Civil-Constitucional. O risco é estudado a partir dos conceitos de liberdade e dignidade, demonstrando que a liberdade não é absoluta, limitada pela dignidade. Nesta acepção, surge o risco, inerente à natureza humana, que é fruto da liberdade, portanto, também, pela dignidade. Na atividade desportiva, o risco é inseparável, o atleta na busca pela superação o assume naturalmente. Assim, a teoria da assunção do risco só se legitima, se presentes o respeito aos valores e princípios constitucionais, principalmente, a dignidade e aceitabilidade social, fatores vitais no estudo dos danos causados na prática desportiva. Por fim, se legítima a aceitação do risco, haverá exclusão do nexo causal.

Ocupando os latifúndios do saber: subsídios para o ensino da ciência na perspectiva politécnica da educação

A presente tese tem por finalidade refletir sobre princípios pedagógico-filosóficos para o ensino da ciência na etapa intermediária da educação escolar. Considerando que tanto a prática educativa quanto a prática científica são práticas sociais mediadoras do processo de produção, e que, portanto, não se pode pensá-las fora de um método que as integre dialeticamente a partir de determinantes que estão dados no campo da economia política, procurou-se investigar aqui qual é o estatuto hoje reservado à ciência no quadro de valores introduzidos pela economia política neoliberal e os efeitos dessas mudanças sobre o que se prescreve para a formação científica no ensino médio brasileiro a partir da última reforma educacional (LDBEN/1996). Tratou-se de sublinhar aqui as conexões que foram se firmando entre os processos de universalização da forma-mercadoria e as mudanças introduzidas no regime de produção do conhecimento, que vai cada vez mais sendo moldado pelos objetivos e prescrições do capital. Tendo por referência o materialismo histórico-dialético, o objeto desta tese foi delineado de modo a refletir o processo de constituição da produção da ciência em dois âmbitos distintos: o da macro-política, presidido hegemonicamente pelas instituições ligadas ao capital, a partir da década de 1990, e o da relação epistemológica que subjaz à prática científica contemporânea, assinalando a co-relação entre estes processos e os seus nexos causais. Para dar contas destas relações, procedeu-se a uma investigação histórica e filosófica que teve por objetivo mostrar como o conceito de natureza cunhado pelas mãos dos primeiros cientistas no século XVII futura matriz da noção de ciências da natureza tal como ela é tomada hoje no currículo , assentado numa distinção fixa entre juízos de fato e juízos de valor, deve seu conteúdo a um processo que é finalmente econômico e social. Por meio desta crítica pode-se estabelecer os vínculos entre a economia política, o viés institucional da ciência e o universo da epistemologia. Concluiu-se que há uma relação necessária entre o novo registro institucional de produção do conhecimento, garantido por um estatuto regulatório afinado com as demandas do neoliberalismo, e o novo estatuto epistemológico, assinalado por uma ênfase nos pressupostos do realismo científico ingênuo. Esta relação se projeta sobre o ensino da ciência na forma de uma intensificação de seu teor tecnicista, e dentre as suas características destacamos duas: 1) o conceito de natureza, tomado no ensino das ciências como uma abstração des-historicizada; 2) o mito da unicidade científica, isto é, a crença de que só há uma ciência: a que formulará, numa linguagem única e inequívoca, a verdade do real. Para finalizar, fizemos alusão a dois programas educacionais que, a nosso ver, avançam rumo a novas formas de ensino na medida em que refletem a experiência de um grupo de educadores e alunos com os princípios da educação politécnica: o do Instituto de Educação Josué de Castro (IEJC/ITERRA) e o da Escola Politécnica de Saúde Joaquim Venâncio (EPSJV/Fiocruz).

Causation and Harm in a Multicomponent World

On September 17, 2015, the Federal Circuit issued another decision in the epic Apple v. Samsung smartphone war. This was the fourth court decision in the ongoing saga to deal with injunctions. Apple IV explained the level of proof necessary to satisfy the "causal nexus" requirement. This requirement had emerged as a response to patent litigations involving products with thousands of features, the vast majority of which are unrelated to the asserted patent. To prove a causal nexus, patentees seeking an injunction have to do more than just show that the infringing product caused the patentee irreparable harm. The harm must be specifically attributable to the infringing feature. In Apple IV, the Federal Circuit noted that proving causation was "nearly impossible" in these multicomponent cases. So it decided to water down the causal nexus requirement saying that it was enough for Apple to show that the infringing features were "important"and customer sought these particular features. This lower standard is an ill-advised mistake that leaves multicomponent product manufacturers more susceptible to patent holdup. My critique takes two parts. First, I argue that a single infringing feature rarely, if ever, "causes" consumers to buy the infringer’s multicomponent products. The minor features at issue in Apple IV illustrate this point vividly. Thus, the new causal nexus standard does not accurately reflect how causation and harm operate in a multicomponent world. Second, I explain why the court was so willing to accept such little evidence of real injury. It improperly applied notions of traditional property law to patents. Specifically, the court viewed patent infringement as harmful regardless of any concrete consequences. This view may resonate for other forms of property where an owner's rights are paramount and a trespass is considered offensive in and of itself. But the same concepts do not apply to patent law where the Supreme Court has consistently said that private interests must take a back seat to the public good. Based on these principles, the courts should restore the "causal nexus" requirement and not presume causation.

Modelling the water, energy and economic nexus

The mining industry faces three long term strategic risks in relation to its water and energy use: 1) securing enough water and energy to meet increased production; 2) reducing water use, energy consumption and emissions due to social, environmental and economic pressures; and 3) understanding the links between water and energy, so that an improvement in one area does not create an adverse effect in another. This project helps the industry analyse these risks by creating a hierarchical systems model (HSM) that represents the water and energy interactions on a sub-site, site and regional scales; which is coupled with a flexible risk framework. The HSM consists of: components that represent sources of water and energy; activities that use water and energy and off-site destinations of water and produced emissions. It can also represent more complex components on a site, with inbuilt examples including tailings dams and water treatment plants. The HSM also allows multiple sites and other infrastructure to be connected together to explore regional water and energy interactions. By representing water and energy as a single interconnected system the HSM can explore tradeoffs and synergies. For example, on a synthetic case study, which represents a typical site, simulations suggested that while a synergy in terms of water use and energy use could be made when chemical additives were used to enhance dust suppression, there were trade-offs when either thickened tailings or dry processing were used. On a regional scale, the HSM was used to simulate various scenarios, including: mines only withdrawing water when needed; achieving economics-of-scale through use of a single centralised treatment plant rather than smaller decentralised treatment plants; and capturing of fugitive emissions for energy generation. The HSM also includes an integrated risk framework for interpreting model output, so that onsite and off-site impacts of various water and energy management strategies can be compared in a managerial context. The case studies in this report explored company, social and environmental risks for scenarios of regional water scarcity, unregulated saline discharge, and the use of plantation forestry to offset carbon emissions. The HSM was able to represent the non-linear causal relationship at the regional scale, such as the forestry scheme offsetting a small percentage of carbon emissions but causing severe regional water shortages. The HSM software developed in this project will be released as an open source tool to allow industry personnel to easily and inexpensively quantify and explore the links between water use, energy use, and carbon emissions. The tool can be easily adapted to represent specific sites or regions. Case studies conducted in this project highlighted the potential complexity of these links between water, energy, and carbon emissions, as well as the significance of the cumulative effects of these links over time. A deeper understanding of these links is vital for the mining industry in order to progress to more sustainable operations, and the HSM provides an accessible, robust framework for investigating these links.

Nexus between contracting and construction professional service businesses: empirical evidence from international market

he construction market around the world has witnessed the growing eminence of construction professional services (CPSs), such as urban planning, architecture, engineering, and consultancy, while the traditional contracting sector remains strong. Nowadays, it is not uncommon to see a design firm taking over the work of a traditional main contractor, or vice versa, of overseeing the delivery of a project. Although the two sectors of contracting and CPS share the same purpose of materializing the built environment, they are as different as they are interrelated. Much has been mentioned about the nexus between the two but little has been done to articulate it using empirical evidence. This study examined the nexus between contracting and CPS businesses by offering and testing lead-lag effects between the two sectors in the international market. A longitudinal panel data composed of 23 top international contractors and CPS firms was adopted. Surprisingly, results of the panel data analyses show that CPS business does not have a significant positive causal effect on contracting as a downstream business, and vice versa. CPS and contracting subsidiaries, although within the same company, do not necessarily form a consortium to undertake the same project; rather, they often collaborate with other CPS or contracting counterparts to undertake projects. This paper provides valuable insights into the sophisticated nexus between contracting and CPS in the international construction market. It will support business executives’ rational decision making for selecting proper contracting or CPS allies, or a proper mergers and acquisitions strategy in the international market. The paper also provides a fresh perspective through which researchers can better investigate the diversification strategies adopted by international contracting and CPS firms.

Electricity consumption–real GDP causality nexus: Evidence from a bootstrapped causality test for 30 OECD countries

The goal of this paper is to examine any causal effects between electricity consumption and real GDP for 30 OECD countries. We use a bootstrapped causality testing approach and unravel evidence in favour of electricity consumption causing real GDP in Australia, Iceland, Italy, the Slovak Republic, the Czech Republic, Korea, Portugal, and the UK. The implication is that electricity conservation policies will negatively impact real GDP in these countries. However, for the rest of the 22 countries our findings suggest that electricity conversation policies will not affect real GDP.

The energy consumption - real GDP nexus revisited : empirical evidence from 93 countries

In this paper, we analyse the long-run relationship between energy consumption and real GDP for 93 countries. We find mixed results on the impact of energy consumption on real GDP, with greater evidence at the country level supporting energy consumption having a negative causal effect on real GDP. For the G6 panel of countries, we find significant evidence that energy consumption negatively Granger causes real GDP. This means that for countries where energy consumption has a negative long-run causal effect on real GDP, energy conversation policies should not retard economic growth. We identify these countries and regional panels. We argue that these countries/regions should play a greater role in reducing carbon dioxide emissions.

O nexo causal entre crédito rural e crescimento do produto agropecuário na economia brasileira

O nexo causal entre desenvolvimento financeiro e crescimento econômico vem ganhando destaque na literatura desde o início dos anos 1990. As principais linhas teóricas nessa área buscam demonstrar qual a significância da relação e o sentido da causalidade, se houver. Causalidade unidirecional no sentido do desenvolvimento financeiro para o crescimento econômico, bicausalidade entre ambos, e causalidade reversa, no sentido do crescimento para o desenvolvimento financeiro, são as principais hipóteses testadas nas pesquisas empíricas. O presente trabalho de tese tem por objetivo avaliar o nexo causal entre crédito (como um indicador do desenvolvimento financeiro) e crescimento no setor agropecuário brasileiro. O crédito rural como proporção do PIB agropecuário cresceu substancialmente desde meados da década de 90, passando de 15,44% em 1996 para 65,24% em 2014. Ao longo do período 1969-2014, a razão média anual entre crédito rural e PIB agropecuário foi de 43,87%. No mesmo período, o produto agropecuário cresceu em média 3,76% ao ano. Questiona-se se no mercado rural o crédito causa o crescimento agropecuário, se ocorre causalidade reversa ou se se opera a hipótese de bicausalidade. Para avaliar o nexo causal entre essas duas variáveis econômica foram empregados quatro procedimentos metodológicos: teste de causalidade de Granger em uma representação VAR com a abordagem de Toda e Yamamoto, teste de causalidade de Granger em um modelo FMOLS (Fully Modified OLS), teste de causalidade de Granger em um modelo ARDL (Autoregressive-Distributed Lag) e teste de causalidade de Granger no domínio da frequência, com o uso do método de Breitung e Candelon. Os resultados mostram de forma uniforme a presença de causalidade unidirecional do crédito rural para o crescimento do produto agropecuário. Causalidade reversa, no sentido do crescimento agropecuário para o crédito rural, não foi detectada de forma significativa em nenhum dos quatro métodos empregados. A não detecção de bicausalidade pode ser uma evidência do impacto da forte política de subsídio governamental ao crédito rural. A decisão do Governo quanto ao montante anual de crédito rural disponível a taxas de juros subsidiadas pode estar impedindo que o desempenho do setor, medido pela sua taxa de crescimento, exerça uma influência significativa na dinâmica do crédito rural. Os resultados também abrem a possibilidade a testar a hipótese de exogeneidade do crédito rural, o que seria uma extensão direta dos resultados obtidos.

The finance-welfare state nexus. ACES Cases No. 2013.1

At the height of the financial crisis, the Western welfare state prevented a repeat of the Great Depression. But there were also suggestions that social policy had contributed to the crisis, particularly by promoting households’ access to credit in pursuit of welfare goals. Others claim that it was the withdrawal of state welfare that led to the disaster. Against this background that motivated our interest, we propose a systematic way of assessing the relationship between financial market and public welfare provisions. We use structural vector auto-regression to establish the causal link and its direction. Two hypotheses about this relationship can be inferred from the literature. First, the notion that welfare states ‘decommodify’ livelihoods or that there is an equity-efficiency tradeoff would suggest that welfare states substitute to varying degrees for financial market offers of insurance and savings. By contrast, welfare states may support private interests selectively and/or help markets for households to function better; thus the nexus would be one of complementarity. Our empirical strategy is to spell out the causal mechanisms that can account for a substitutive or complementary relationship and then to see whether advanced econometric techniques find evidence for the existence of either of these mechanisms in six OECD countries. We find complementarity between public welfare (spending and tax subsidies) and life insurance markets for four out of our six countries, notably even for the United States. Substitution between welfare and finance is the more plausible interpretation for France and the Netherlands, which is surprising. Data availability constrains us from testing the implications for the welfare state contribution to the crisis directly but our findings suggest that the welfare state cannot generally be blamed for the financial crisis.

The productivity-inflation nexus: The case of the Australian mining sector

This paper examines the causal links between productivity growth and two price series given by domestic inflation and the price of mineral products in Australia's mining sector for the period 1968/1969 to 1997/1998. The study also uses a stochastic translog cost frontier to generate improved estimates of total factor productivity (TFP) growth. The results indicate negative unidirectional causality running from both price series to mining productivity growth. Regression analysis further shows that domestic inflation has a small but adverse effect on mining productivity growth, thus providing some empirical support for Australia's 'inflation first' monetary policy, at least with respect to the mining sector. Inflation in mineral price, on the other hand, has a greater negative effect on mining productivity growth via mineral export growth.

Contradictions : Genre, causal layered analysis and analysis of institutional change

In what follows, I put forward an argument for an analytical method for social science that operates at the level of genre. I argue that generic convergence, generic hybridity, and generic instability provide us with a powerful perspectives on changes in political, cultural, and economic relationships, most specifically at the level of institutions. Such a perspective can help us identify the transitional elements, relationships, and trajectories that define the place of our current system in history, thereby grounding our understanding of possible futures.1 In historically contextualising our present with this method, my concern is to indicate possibilities for the future. Systemic contradictions indicate possibility spaces within which systemic change must and will emerge. We live in a system currently dominated by many fully-expressed contradictions, and so in the presence of many possible futures. The contradictions of the current age are expressed most overtly in the public genres of power politics. Contemporary public policy—indeed politics in general-is an excellent focus for any investigation of possible futures, precisely because of its future-oriented function. It is overtly hortatory; it is designed ‘to get people to do things’ (Muntigl in press: 147). There is no point in trying to get people to do things in the past. Consequently, policy discourse is inherently oriented towards creating some future state of affairs (Graham in press), along with concomitant ways of being, knowing, representing, and acting (Fairclough 2000).

Developing a model of technology appropriation: A Marxian perspective

This paper explores the philosophical origins of appropriation of Information Systems (IS) using Marxian and other socio-cultural theory. It provides an in-depth examination of appropriation and its application in extant IS theory. We develop a three-tier model using Marx’s foundational concepts and from this generate four propositions that we test in an empirical example of IS in anesthesia. Using Marxian theory, this paper seeks common ground among existing theories of technology appropriation in IS research. This work contributes to IS research by (1) opening philosophical discussions on appropriation and the human ↔ technology nexus, (2) drawing on these varying perspectives to propose a general conceptualization of technology appropriation and (3) providing a starting point towards a general causal model of technology appropriation.
