A New Robust Epigenetic Model for Forensic Age Prediction

Forensic DNA phenotyping refers to an emerging field of forensic sciences aimed at the prediction of externally visible characteristics of unknown sample donors directly from biological materials. The aging process significantly affects most of the above characteristics making the development of a reliable method of age prediction very important. Today, the so-called “epigenetic clocks” represent the most accurate models for age prediction. Since they are technically not achievable in a typical forensic laboratory, forensic DNA technology has triggered efforts toward the simplification of these models. The present study aimed to build an epigenetic clock using a set of methylation markers of five different genes in a sample of the Italian population of different ages covering the whole span of adult life. In a sample of 330 subjects, 42 selected markers were analyzed with a machine learning approach for building a prediction model for age prediction. A ridge linear regression model including eight of the proposed markers was identified as the best performing model across a plethora of candidates. This model was tested on an independent sample of 83 subjects providing a median error of 4.5 years. In the present study, an epigenetic model for age prediction was validated in a sample of the Italian population. However, its applicability to advanced ages still represents the main limitation in forensic caseworks.     

Family farming in Brazil: evolution between the 1996 and 2006 agricultural censuses

This article compares the main findings of Brazilian agricultural census data of 1996 with the same of 2006 by applying the methodology known as ‘FAO/INCRA’ (Food Agriculture Organization/Instituto Nacional de Colonização e Reforma Agrária) which allows the characterization of family farms in relation to the total universe of farms. In this comparison several variables are shown, including the share of family farming in the total value of production, in the total number of farms, utilization of modern technology and partial factor productivity. Census data shows that family farming has changed from 37.91 percent of total production value to 36.11 percent during a decade of strong expansion of agriculture as a whole, demonstrating the economic relevance of this segment which, besides producing food, is integrated in the most important productive agricultural chains of the Brazilian agribusiness. Family farming is a heterogeneous segment, with different sub-segments. During the studied period of ten years the most rich of these sub-segments (A) has increased participation in total production, while the poorer sub-segments (C and D) have only grown in absolute terms without a corresponding increase in production.     

Male haplotypes and haplogroups differences between urban (Rimini) and rural area (Valmarecchia) in Romagna region (North Italy)

The distribution of Y chromosomal haplotypes and haplogroups in two different population samples from the Romagna region (North Italy) was performed. One population sample was collected in the urban area of Rimini, an ancient port in Roman age and the other one in the near and geographically more isolated rural area of Valmarecchia. Fast and slow evolving markers have been studied to infer population history and to analyse the microgeographic heterogeneity of Y chromosome in a Northern Italian region. Haplotype variability values compared to those observed in a Central Italy sample from the other side of Apennine mountains and in an Austrian population sample were very similar.

Levelling the EU participatory playing field: A legal and policy analysis of the Commission's public consultations in light of the principle of political equality

The EU Commission has a long tradition of consulting interested parties when formulating its policies. While the rationale, format and legal basis relied upon by the Commission when holding public consultations have changed over time, its systematic inability to make those consultations equally accessible to all affected parties has remained constant. This article discusses the extent to which such a consultation practice conflicts with the principle of political equality, as enshrined in Article 9 TEU. Given the Commission's unrestrained discretion regarding who, how and when to consult and the absence of corresponding participatory rights, it argues that the EU can no longer presume that all stakeholders—especially citizens and civil society groups—enjoy equal access to EU institutions. Rather, under a proposed substantive reading of the principle of political equality, it contends that EU institutions are procedurally required to ensure that everyone will effectively be given equal opportunities of access to the policy process. Only a series of structural, power‐shifting reforms—some of which are proposed in this article—may enable participation to become an autonomous form of legitimation of the Union.     

Inquiring into the political economy of oil palm as a global flex crop

Oil palm production and consumption, and the trade of its multiple commodities, have expanded exponentially in recent decades. This paper argues that this expansion will continue due to, and along with, the rise of ‘flexing’ among its increasing multiple uses, especially for more industrial and energy purposes. Oil palm has been extensively analysed in the context of land grabs and agrarian change, land conversion and deforestation. However, its nature as a flex crop remains unexplored, especially with respects to the convergence of global food, fuel and environmental crises. This paper provides a preliminary discussion of how oil palm fits in the flex-crop framework to analyse its enabling material and ideational bases, as well as who informs, decides and controls the nature of flexing. This is done through an analysis of the different roles played by state, corporate (private) and social actors in the flexing of oil palm across the globe. We conclude by drawing some implications for further research.     

The discursive flexibility of ‘flex crops’: comparing oil palm and jatropha

‘Flex crops’ such as corn, oil palm and soy are understood to have multiple, interchangeable uses; they have material flexibility. We propose that discursive flexibility – the ability to strategically switch between discourses to promote an objective – equally shapes the political economy of flex crops, and thereby patterns of agrarian and environmental change. Comparing oil palm and Jatropha curcas, we find that actors who cast oil palm as a multi-scale solution to food and energy insecurity, climate change and (rural) poverty successfully reinforce its high material flexibility. Jatropha's proponents compensate for low material flexibility by positioning the crop as a ‘sustainable’ energy source that achieves both global and local goals. While this paper focuses on discourses that reinforce the oil palm and jatropha projects, understanding the power of discursive maneuvering can also inform efforts to contest them.     

Language nuances, trust and economic growth

Language serves two key functions. It enables communication between agents, which allows the set-up and functioning of formal and informal institutions. It also serves a less obvious function, as it provides a reassuring quality more closely related with issues linked with trust, social capital, and cultural identification. While research on the role of language as a learning process is widespread, there is no evidence on the role of language as a signal of cultural affinity. We pursue this latter avenue of research and show that subtle language affinity is positively linked with change in earnings when using English-speaking data for cities in the Golden Horseshoe area in Southern Ontario during the period 1991 to 2001. The results are robust to changes in specification, and a broad number of empirical tests.     

Political and institutional environment and privatization prices

We study the link between the political and institutional context and privatization sales prices. The latter serves as a measure for assessing the extent to which privatization goals have been met. Whereas this link has been studied theoretically, there are very few, if any, empirical papers on this relationship. We use data from 308 privatizations around the world and apply a cross-country approach, including instrumental variables. We find that while the overall political regime does not matter much for prices, the political processes beyond the basic regime do matter. Institutional context also produces a significant impact on prices. Both results are robust to changes in specification.     

The Impact of Natural Disasters on Remittances to Low- and Middle-Income Countries

In this paper, we offer novel empirical evidence on the impact of natural disasters on remittance flows towards low- and middle-income countries. We consider a panel of 98 countries over the period 1990–2010. Our findings show that remittances increase after a disaster, thus contributing ex post to the reconstruction process. At the same time, we find that remittances play a key role in terms of ex ante risk preparedness for those countries that experienced more disruptive events in the past. Finally, when taking into account the interaction with the level of development of the local financial sector, remittances seem to substitute for less efficient financial systems both in terms of ex post response to disasters and in terms of ex ante risk management strategy.
