On the Relationship between Violent Conflict and Wages in Colombia

We analyse how forced displacements caused by violent conflict are related to the wages of workers in Colombia. Using data from the Quality of Life Survey (2011–2014), we analyse the differences in wages between those forced by violence to move to other regions, and those who moved for other reasons. We apply Propensity Score Matching techniques to compare workers from the two groups, finding that forced displacement is related to decreases of between 10 and 29 per cent in the wages of males, and between 18 and 37 per cent in the wages of females, relative to their counterparts. Thus, forced displacements are related to poorer labour market outcomes in terms of wages.     

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.
