Demobilization of Paramilitaries in Colombia: Transformation or Transition?

Historically, Disarmament, Demobilization, and Reinsertion (DDR) has provided a useful means to terminate conflicts. Since being catapulted to office in August 2002 with 53 percent of the vote of 46.45 percent of the voters, ¹ 1. IFES Election Guide, available at (http://www.electionguide.org/results.php?ID=1011). Colombian President Álvaro Uribe has vigorously pursued a demobilization program, both individual and collective. However, despite the fact that over 40,000 combatants have demobilized under these programs, evidence is growing that this latest round of Colombian DDR is merely transitioning, rather than terminating, violence in that Andean country.     

Internet applications in the political sphere: perceptions and views of political institutions in South Africa

Abstract

The study described in this article consisted of a survey that was conducted among a sample of South African political institutions and organisations, and that was aimed at investigating their views and perceptions with regard to the use of the Internet. The main research question posed by the current study was: What are the views of politically orientated institutions in South Africa on their use the Internet, and what are their perceptions on how the Internet could impact on democratic processes in the country? The aim of this exploratory research study was to obtain information that could cast light on the issue of how likely it was that the Internet would contribute to a deliberative democracy in South Africa. The survey revealed that the Internet was perceived to have a significant role to play with regard to political and democracy issues in South Africa. However, if certain problems (the lack of access, the lack of basic and computer literacy, and the lack of training) were not adequately addressed by means of an integrated government Internet strategy, the ability of the Internet to impact positively on democracy in South Africa would be very limited.     

A critical evaluation of the Downs-Hazen instrument (CSQ) by measuring employee communication satisfaction at a private higher education institution in South Africa

Abstract

The aim of this article is to provide a critical evaluation of the Downs-Hazen instrument (Communication Satisfaction Questionnaire) (CSQ) by applying it to the measurement of employee communication satisfaction at a private higher education institution in South Africa. Three communication satisfaction dimensions, consisting of eight constructs, were measured. The results indicated that although employees are satisfied with their relationship with superiors, a need exists for improved communication on the psychological atmosphere in the organisation; the information employees receive about their immediate work environments, meetings and written directives; horizontal and informal communication that is accurate and free flowing; information about the organisation as a whole; as well as the way in which employees are being judged and appraised.

A final conclusion is that the Downs-Hazen CSQ is still applicable even though it was first developed almost 30 years ago. Furthermore, the adjustments to items in this study did not affect the reliability of the adapted questionnaire.     

Forensic determination of hair deposition time in crime scenes using electron paramagnetic resonance

Several types of biological samples, including hair strands, are found at crime scenes. Apart from the identification of the value and the contributor of the probative evidence, it is important to prove that the time of shedding of hair belonging to a suspect or victim matches the crime window. To this end, to estimate the ex vivo aging of hair, we evaluated time‐dependent changes in melanin‐derived free radicals in blond, brown, and black hairs by using electron paramagnetic resonance spectroscopy (EPR). Hair strands aged under controlled conditions (humidity 40%, temperature 20–22°C, indirect light, with 12/12 hour of light/darkness cycles) showed a time‐dependent decay of melanin‐derived radicals. The half‐life of eumelanin‐derived radicals in hair under our experimental settings was estimated at 22 ± 2 days whereas that of pheomelanin was about 2 days suggesting better stabilization of unpaired electrons by eumelanin. Taken together, this study provides a reference for future forensic studies on determination of degradation of shed hair in a crime scene by following eumelanin radicals by utilizing the non‐invasive, non‐destructive, and highly specific EPR technique.     

The black soldier-fly, Hermetia illucens (Diptera, Stratiomyidae), used to estimate the postmortem interval in a case in Amapá State, Brazil

The black soldier-fly (Hermetia illucens) is a generalist detritivore which is commonly present in corpses in later stages of decomposition and may be useful in forensic entomology. This paper describes the estimation of the postmortem interval (PMI) based on the life cycle of the black soldier-fly in a case in northern Brazil. A male child was abducted from his home and 42 days later his corpse was found in an advanced stage of decay. Two black soldier-fly larvae were found associated with the body. The larvae emerged as adults after 25-26 days. Considering the development cycle of H. illucens, the date of oviposition was estimated as 24-25 days after abduction. Since H. illucens usually (but not always) colonizes corpses in more advanced stages of decay, this estimate is consistent with the hypothesis that the child was killed immediately after abduction.     

Application of the Iscan method to two- and three-dimensional imaging of the sternal end of the right fourth rib

Age determination is a major field of interest in physical and forensic anthropology. Among the different methods based on macroscopic skeletal study, the Iscan method, which analyzes the sternal end of the right fourth rib, is one of the most reliable. We applied the Iscan method to two- and three-dimensional multislice computed tomography (MSCT) reconstructions of the sternal end of the right fourth rib on 39 ribs. The intra-observer variability on MSCT reconstructions was good (gamma coefficient equal to 0.86; value of the Krippendorff's alpha reliability equal to 0.79); inter-observer variability on MSCT reconstructions was also good (gamma coefficient ranging from 0.82 to 0.88; value of the Krippendorff's alpha reliability ranging from 0.78 to 0.86). We demonstrated excellent agreement between the results of analysis of bone samples and those of the two- and three-dimensional images, in particular regarding bone projections, morphology of the pit and of its rim. The accuracy of age estimation did not significantly differ between the Iscan method applied to dry bones and the same method applied to MSCT images. Determination of the Krippendorff's alpha reliability coefficient for the inter-error method confirmed the agreement between phase estimations obtained with the two methods (ranging from 0.55 to 0.71). The real civil age was comprised in 21 cases out of 36 for assessment performed on dry bones and in 23 cases out of 36 on MSCT reconstructions, which represented 58.3% and 63.9%, respectively. Use of MSCT reconstructions in forensic anthropology offers many advantages: no bone preparation, no damage to bone material, and the possibility of application to living individuals.
