Exploring the Effects of North–South and South–South Research Collaboration in Emerging Economies,the Colombian Case

International research collaboration (IRC) is associated with both positive and negative effects on the performance of research in emerging economies. While some authors claim that North–South collaborations improve scientific quality and visibility for Southern countries, others claim that it may entail the reorientation of research to comply with Northern agendas. South–South collaborations are thought to increase the focus on local affairs, therefore leading to a relatively small number of scientific international publications appearing in “high quality” journals. Research on the impact of IRC beyond publications in international journals has been neglected despite the importance of other products in knowledge creation. This research uses a broad range of scientific outputs to empirically assess such assumptions and explore the outcomes of IRC in Colombia. Results from multivariate regressions and nonparametric analyses show that, contrary to common assumptions, Colombian research teams collaborating with partners from the global South report higher scientific production, while those collaborating with Northern countries seem to contribute to local knowledge the most.     

Bolivia's soy complex: the development of ‘productive exclusion’

A significant transition is underway in Bolivia where both domestic and foreign capital are monopolizing commercial agriculture and leading a highly mechanized, capital-intensive production model which has considerably diminished the need for labour. This paper explores mechanisms and processes of ‘productive exclusion’ in the soy-producing zones of Santa Cruz in relation to the expansion, concentration and mechanization of the ‘soy complex’. We provide an analysis of how the agrarian structure has developed since soy was adopted – from ‘putting land into production’ to ‘expanding the agricultural frontier’ and ‘controlling the agro-industrial chain’. We explore how and the extent to which the penetration of new capital is leading to new processes of agrarian change which exclude the rural majority from accessing the means of production. While a process of ‘foreignization’ of land began to take shape in the early 1990s, new processes of capital accumulation are eroding the ability of small farmers to engage in productive activity, potentially leading to ‘surplus’ populations no longer needed for capital accumulation.

The application of differential thermal analysis and thermogravimetric analysis to dating bone remains.

Thirty-four samples of bone remains of known time since death were studied by using DTA, TGA, and derivative-TGA techniques. The DTA patterns enable us to distinguish recent from old (more than 100 years) bones. The TGA curve is also significant for an extreme series. Both DTA and TGA curves show a correlation that allows us to obtain patterns with high significance for the extreme series. They also make evident the decomposition grade that bone organic material undergoes during the postmortem putrefactive process.     

Study of cathepsin A, B and D activities in the skin wound edges. Its application to the differential diagnosis between vital and postmortem wounds

The aims of the authors in this paper has been to check the diagnostic ability of the Cathepsin A, B and D concentrations in the skin wound edges to the differential diagnosis between vital and postmortem wounds. We have studied 56 domestic pigs grouped in seven experimental series consisting of 8 animals in each, according to the time (0, 5, 15, 30 min and 1, 3 and 6 h) after the injury. The enzymatic activities were investigated following the methods by Bowen and Davison Biochem. J., 131 (1973) 417-419, Suhar and Marks J. Biochem., 101 (1979) 23-30 and by Anson (modified by Yamamoto, Eur. J. Biochem., 95 (1979) 459-467) for Cathepsin A, B and D, respectively. For the differential diagnosis between vital and postmortem wounds, our results showed that the most useful markers studied are the Cathepsin A and D activities, Cathepsin D that of the first one.     

Public and private sector wages interactions in a general equilibrium model

It is common wisdom that public sector wages are not determined in the same way as private sector wages. At the same time, the empirical evidence available for OECD countries finds a strong positive correlation between public and private sector wages. In this paper, we develop a model that is consistent with a political economy view of the determination of public sector wages and employment, while being consistent with the said empirical evidence. Public finance constraints are crucial: In booms, governments expand employment and wages, while in downturns, lack of tax revenues forces the government to cut back the wage bill.     

Postnatal ontogenesis of the tibia. Implications for age and sex estimation

The growth of five variables of the tibia (diaphyseal length, diaphyseal length plus distal epiphysis, condylo-malleolar length, sagittal diameter of the proximal epiphysis, maximum breadth of the distal epiphysis) were analysed using polynomial regression in order to evaluate their significance and capacity for age and sex determination during and after growth. Data were collected from 181 (90♂ and 91♀) individuals ranging from birth to 25 years of age and belonging to three documented collections from Western Europe. Results indicate that all five variables exhibit linear behaviour during growth, which can be expressed by a first-degree polynomial function. Sexual significant differences were observed from age 15 onward in the two epiphysis measurements and condylo-malleolar length, suggesting that these three variables could be useful for sex determination in individuals older than 15 years. Strong correlation coefficients were identified between the five tibial variables and age. These results indicate that any of the studied tibial measurements is likely to serve as a useful source for estimating sub-adult age in both archaeological and forensic samples.     

Regional Trade Agreements and the Neo-Colonialism of the United States of America and the European Union: A Review of the Principle of Competitive Imperialism

The recent proliferation of Regional Trade Agreements (RTAs) in the last two decades raises questions about the paradigm shift from the multilateral trading system of the World Trade Organization (WTO) to bilateral and regional preferential trade arrangements. Even more questionable is the fact that the United States of America (USA) and the European Union (EU), among the other trading powers of the world, are leading the use of RTAs to the detriment and neglect of non-discriminatory trade liberalisation. It has been suggested that neo-colonialism may be the motivation for the use of RTAs by the USA and the EU as their international trade policy of choice within a broader competitive process for imperial domination of their preferential trading partners. This article reviews this suggestion in order to propose an alternative explanation for the RTA practice of the USA and the EU.     

Intentional mixed buccal cell reference sample in a paternity case

We report a case where an alleged father (AF) attempted to substitute someone else's saliva sample for his reference sample in a paternity analysis. Buccal cells were collected from the AF and the child, and DNA analysis was performed using an autosomal STR loci (Identifiler). The profile from the AF showed extra peaks in some loci, as well as a much higher "X" allele peak relative to the "Y" allele peak at the amelogenin locus. After conducting reanalysis by another technician with another set of positive and negative controls, it was concluded that the only source of the mixed profile was by intentional introduction by the AF, at the time of sampling, of some foreign human biological material, most likely saliva from a woman. Owing to the inconclusive results, when the AF was called back to the lab and the peculiar results were explained to him, he admitted that he had introduced into his mouth saliva from another person in an attempt to be excluded as the father of the child. Although tampering with DNA reference samples is not common, some individuals may attempt to contaminate or otherwise adulterate specimens before DNA tests. Personnel responsible for sampling should be aware of this possibility and should try to establish procedures to avoid the problem.     

Current challenges of the mexican state and of mexican public administration

This article deals with the problems that the Mexican government will need to face in order to go on with the reform of the state. The cycle of such a reform (privatization, liberalization and democratization) is already closing down. While ending this process, however, Mexico also started to see an increasing number of demands calling for administrative reform and, above all, the federalization of government and public administration. This is what the author calls the strategic agenda of the Mexican government.

In order to implement the administrative reform, the author favors enhancing the accountability of the Mexican government, by increasing public participation in the policy and decision making processes. With regard to the federalization of government and public administration, Aguilar proposes the implementation of policy tools never used in Mexico, such as fiscal federalism (categorical and block grants, for instance), together with new constitutional, political and administrative arrangements.
