Property and the cloud

Data is a modern form of wealth in the digital world, and massive amounts of data circulate in cloud environments. While this enormously facilitates the sharing of information, both for personal and professional purposes, it also introduces some critical problems concerning the ownership of the information. Data is an intangible good that is stored in large data warehouses, where the hardware architectures and software programs running the cloud services coexist with the data of many users. This context calls for a twofold protection: on one side, the cloud is made up of hardware and software that constitute the business assets of the service provider (property of the cloud); on the other side, there is a definite need to ensure that users retain control over their data (property in the cloud). The law grants protection to both sides under several perspectives, but the result is a complex mix of interwoven regimes, further complicated by the intrinsically international nature of cloud computing that clashes with the typical diversity of national laws. As the business model based on cloud computing grows, public bodies, and in particular the European Union, are striving to find solutions to properly regulate the future economy, either by introducing new laws, or by finding the best ways to apply existing principles.     

Agribusiness,Legislative Elections and Party Fragmentation in Brazil

The article explores the impact of agribusiness on the politics of legislative elections in Brazil. The central argument is that social contexts dominated by agribusiness tend to amplify the number of right-wing micro-parties, due firstly to the economic interests prevalent in such regions and secondly given the ‘catch all’ nature of Brazil's traditional right and centre-right political parties. By showing how agribusiness favours the proliferation of small parties, we may also reveal one of the main reasons behind the ‘hyperfragmentation’ of Brazil's party system.     

Child Suicide in the North of Portugal

Suicide in children is a rare finding and is probably motivated by acts of impulsiveness. This study aims to contribute to the characterization of child suicide in a forensic perspective in the Portuguese population. Data of forensic autopsies from 2004 to 2012 related to suicide victims under 18 years were reviewed. A total of 17 cases, with a male predominance (64.7%) and a mean age of 15.24 ± 1.348 for both genders, were registered. The leading suicide method was hanging (35.3%), and a suicide note was found in 41.2%. Psychological autopsy proved to be useful in promoting a better understanding of these incidents and their antecedents. This study also offers useful information, namely the implied risk factors, for future programs of suicide research and prevention.     

Chemical identification and optimization of the 4-aminophenol colorimetric test for the differentiation between hemp-type and marijuana-type cannabis plant samples

The 4- Aminophenol (4-AP) colorimetric test is a fast, easy-to-use, and cost-effective presumptive assay of cannabis plant material producing different chromophores with THC-rich cannabis (blue color) and with CBD-rich cannabis (pink color). The main drawback of the 4-AP test is a brief observation window where the color rapidly changes to black, limiting the utility of the test. We now report for the first time, the identification of the product chromophores between 4-AP and CBD/THC as well as propose an explanation and a solution for the color degradation of the chromophores. The identification of the chromophores is provided by spectroscopic (UV–Vis), chromatography, and mass spectrometry (TLC and LC-QToF-MS). Oxidation of excess 4-AP (Reagent A) in the presence of NaOH (Reagent B) produces the black color observed for the previously reported 4-AP tests and reported in the literature. The adjustment of reactants concentrations and volumes of 4-AP:THC/CBD to a 1:1 ratio significantly reduces the black oxidation by-product and increases the observation window up to 2 h instead of the previously reported 5–10 min. For the first time, mass spectrometry and chromatography confirmed that the reaction of THC and CBD with 4-AP produced chromophores with m/z (M + H) = 420, consistent with proposed indophenol structures. The TLC method developed confirmed the separation between CBD and THC chromophores. The specificity of the test is also reported, showing false positive results for the presence of THC (blue color) for samples of thyme and oregano. LDA and SIMCA models showed that the optimized 4-AP procedure performs better than the previously reported 4-AP color test.     

Pregnancy and Intimate Partner Violence in Canada: a Comparison of Victims Who Were and Were Not Abused During Pregnancy

The purpose of this study was to examine risk factors, indicators of severity, and differences in post-violence health effects for victims who experienced intimate partner violence (IPV) during pregnancy compared to victims who experienced IPV outside the pregnancy period. Data were from Statistics Canada’s 2009 General Social Survey. Among IPV victims, 10.5 % experienced physical and/or sexual violence during pregnancy. Victims who had experienced violence during pregnancy were more likely than victims who were not abused during pregnancy to experience both less severe and more severe forms of violence. In fully adjusted models, younger age, separated or divorced marital status, as well as partners’ patriarchal domination, destruction of property, and drinking were significant predictors of pregnancy violence. Measures indicative of more severe violence and of a number of adverse post-violence health effects were significantly elevated among victims who experienced pregnancy violence relative to victims who were not abused during pregnancy. Implications of these findings are discussed.     

An Inquiry into a Normative Concept of Legal Efficacy

This essay argues that legal efficacy understood as existent binding force and as dominance of a system of coercion vis‐à‐vis competing systems is not strictly a matter of fact, but involves what can be termed justified normativity in a factual context. The argument is divided into four sections. The first three sections describe different dimensions of a normative concept of legal efficacy applied to legal systems: efficacy as persuasiveness, as indirect communication, and as constitutive obedience. The final section focuses on the efficacy of individual norms and adds a new criterion – membership – which establishes a multi‐layered test of efficacy.
