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.     

Twenty-Two Ways to Lose a Debate: A Gricean Look at the <Emphasis Type="Italic">Nyāyasūtra</Emphasis>’s Points of Defeat

This paper is a study of debate practices as seen in the Nyāyasūtra and a number of commentaries. It concentrates on the ‘Points of Defeat’ (nigrahasthāna), i.e., those occasions that if met in debate would entail defeat. The conditions under which a debater would meet with defeat were discussed widely in India and have also attracted considerable attention from modern scholars. In order to better understand this subject, use is made of some of the intuitions about language and conversation that we owe to the philosopher H. P. Grice (1913–1988) as well as of some recent theoretical advances in argumentation theory and informal logic, particularly of those most influenced by Grice’s thought. The Points of Defeat are studied both individually and as a group and it is shown that they point towards the practice of debating as being a rational, cooperative and goal-directed activity.     

Macroscopic,Microscopic, and Chemical Assessment of Gunshot Lesions on Decomposed Pig Skin

Abstract: Very little literature exists on gunshot wounds on decomposed material. In this study, seven pig heads underwent a shooting test. Entrance wounds from the first head underwent neutron activation analysis (NAA) and histological testing immediately after the firing test; the other six heads were exposed to two different environments (open air and soil) and analyzed by radiochemical and histological tests every 15 days. Gunshot wounds in air maintained their morphological characteristics, and those in soil showed severe alteration after 5 weeks. Microscopic testing verified positive results for lead in all gunshot wounds in open air, whereas in most of those in soil lead could not be detected. Radiochemical analysis performed by NAA yielded for all gunshot wounds but one antimony quantities in the range of 0.07–13.89 μg. In conclusion, it may be possible to detect residues of antimony even in degraded tissues.     

Fatal Drowning Accident and Undiagnosed Hydrocephalus

Abstract: Bodies found in water present several diagnostic challenges for the forensic examiner, such as the identification of the time and mechanism of death, the postmortem submersion time, and above all the circumstances of drowning. We report the case of a 33‐year‐old security guard found dead in Venice, in the water of the lagoon, who at autopsy presented a previously undiagnosed hydrocephalus with macrocephaly. The victim remained asymptomatic until 2 months before death and had never undergone a neurological or radiological examination. In the article, we emphasize the need to perform a thorough autopsy in all suspected drownings, discuss the etiopathogenesis of the neurological disease and hypothesize a possible relationship between the hydrocephalus and the drowning accident. Finally, we discuss the major clinical and forensic implications of macrocephaly and hydrocephalus in adults.     

Educación jurídica,investigación y derechos humanos inteligentes

The recent studies on the genes, the neurons and the information, are influencing the form to know us and to know the reality. The opportunity is had, for this reason, to improve the formation of the professor and the students of the Right, to happen of an education of repetitions to one of new features, discovery, diversion, that is to say, investigation. One is to avoid “to transmit” information, but to explore it, to construct it, only to invent it, working in equipment, professor and students, inside and outside the hall classes. The contents to investigate can be placed in the past, the present or in the future, like the human rights. Thus, it is tried that the well-known or effective human rights, the products of the legal rationalism, are extended to protect the emotional human dignity: the respect, the confidence, the tolerance, the responsibility, the happiness, desire, the pleasure. Human intelligence is multiple, for that reason the human rights must be intelligent, that protect and develop the intellect, the affectivity, the corporal one, the energy, the environment and its cosmovisión.     

Gunshot residues on dry bone after decomposition-a pilot study

Abstract: Very little literature exists concerning radiochemical and microscopic analyses of gunshot wounds in decomposed material, and even less concerning skeletonized samples; the most advanced technologies may provide useful indications for the diagnosis of suspect lesions, especially if gunshot wounds are no longer recognizable. However, we know very little of the survival of gunshot residues (GSR) in skeletonized samples. This study examined nine gunshot wounds produced on pig heads which then underwent skeletonization for 4 years, and four gunshot entries on human heads from judicial cases which were then macerated to the bone in water; the samples underwent scanning electron microscopy coupled with energy dispersive X‐ray (SEM‐EDX) analysis. Positive results for GSR were observed only in four of the nine animal samples and in all four human samples. Among the human samples, two lesions showed Pb and Sb, one lesion only Pb, and one Pb, Sb, and Ba. This pilot study showed the survival of GSR in skeletal material and therefore the crucial importance of SEM‐EDX analyses on skeletonized material. Further studies are needed in order to ascertain the role of environmental modifications of GSR.     

Spatial patterning of vulture scavenged human remains

This article presents the results of a pilot study on the effects of vulture modification to human remains. A donated body from the Willed Body Donation Program was placed at the Forensic Anthropology Research Facility (FARF), an outdoor human decomposition laboratory located at Texas State University-San Marcos. The effects of vulture scavenging on the timing and sequence, and the rate of skeletonization, disarticulation, and dispersal were observed via a motion sensing camera and direct observation. Using GIS (Geographic Information Systems) and GPS (Global Positioning System) technologies and spatial analytical methods, the transport of skeletal elements was mapped in order to analyze dispersal and terrain-influenced patterns of active vulture scavenging. Results showed that the initial scavenging took place 37 days after placement at FARF. This delay in scavenging differs from previous research. After the initial appearance of the vultures, the body was reduced from a fully-fleshed individual to a skeleton within only 5h. This underscores the potential for errors in postmortem interval estimations made at vulture scavenged scenes. Additionally, spatial analysis showed that skeletal elements were dispersed by vultures to lower elevations, and that the disarticulation and dispersal of the skeletal elements occurs early in the scavenging sequence.     

Nationalism and democratic construction: the origins of Argentina and Uruguay's political cultures in comparative perspective

The article focuses on the different effects the formation of national identity had on the development of political democracy in Uruguay and Argentina. Uruguay's process of state building after the civil wars relied on political consensus regarding the rules of the game: the concept of political democracy became an integral part of Uruguay's collective identity. In Argentina, political elites after the civil wars divided on the question of national identity and the substance of political democracy. Uruguay's political identity as a partidocracia [rule by parties] is not a guarantee against authoritarianism, but the country's democratic political culture is resilient, permeating even the armed forces. In Argentina, the exclusionist character of the political process invites authoritarianism, whether of the liberal or populist‐democratic variety. This article focuses, first, on the different models of collective identity that developed after independence; second, on the distinct roles played by the two hegemonic parties in each nation ‐ the Colorados under Batlle and the Radicals under Yrigoyen; and finally, on the authoritarian periods both countries experienced in the 1930s.     

The “microwave oven” practice in Brazil

This article presents a forensic case of an unusual illegal cremation of a person using a process colloquially known as the “microwave oven” practice in Brazil. The microwave process involves two actions: placing the victim in a tire stack and then setting the structure on fire using flammable substances to accelerate the progression. A similar practice, identified as “necklacing”, has also been reported in other countries such as South Africa. This report presents a case of microwave oven cremation of a body found in a rural area of Minas Gerais, Brazil. The forensic work helped determine the biological profile and identity of the victim using radiological comparisons. Although the microwave oven cremation practice is rare, it can impose challenges for investigators. Therefore, fully understanding this practice can be helpful to the academic and forensic communities.
