Antropolog铆a forense y construcci贸n de nuevos modelos de identificaci贸n: del caso del EAAF
Este trabajo intenta analizar el modo de trabajo desarrollado por el Equipo Argentino de
Antropolog铆a Forense en la identificaci贸n de los cuerpos de desaparecidos durante la 煤ltima
dictadura militar.
Para ello se apoya en la caracterizaci贸n que hace Kuhn de la ciencia normal, concebida
como aquella investigaci贸n en la cual los cient铆ficos conocen el modo de hacer; en donde la
aceptaci贸n de un paradigma se despliega como adquisici贸n y aplicaci贸n de m煤ltiples habilidades
pr谩cticas simult谩neamente, tales como aplicar conceptos,o emplear t茅cnicas matem谩ticas
acertadas, usar instrumentos y aparatos, reconocer oportunidades donde variar situaciones
te贸ricas o experimentales (Rouse, 1987: 30)
Experimental Studies on perception since Psychology's professionalization in Argentina
Se indaga el lugar que ocuparon los estudios experimentales sobre lapercepci贸n en la psicolog铆a argentina tras la profesionalizaci贸n de lapsicolog铆a. Se describen los tres grupos que sistem谩ticamente se dedicarona dicho tema desde la d茅cada de 1960 a la d茅cada de 1980: CIAL, LIS yUNCy/UNSL. Se examinan sus figuras principales y sus l铆neas deinvestigaci贸n. Se indaga el grado de cohesi贸n que alcanzaron comocomunidad cient铆fica nacional. Desde una perspectiva polic茅ntrica, sedescribe su inserci贸n internacional. Se discuten aspectos institucionales yculturales propios de las carreras de psicolog铆a argentinas que incidieron enla limitaci贸n del desarrollo de los estudios experimentales sobre lapercepci贸n.O presente trabalho questiona o lugar que ocuparam os estudos experimentais sobre a percep莽茫o na Psicologia argentina, depois de sua profissionaliza莽茫o.

Three research groups were identified to be devoted to perception studies during the period 1960鈥檚 to 1980鈥檚: CIAL, LIS and UNCy/UNSL. Their leading figures and research streams are described. It is also inquired the cohesiveness these groups reached as a national scientific community. From a polycentric standpoint, their linkage to the international scientific community is also examined. Finally, some idiosyncratic institutional and cultural issues of Argentine Psychology Programs are discussed regarding the limitations of experimental studies on perception`s development.Fil: Pi帽eda, Maria Andrea.

Constituci贸n de la investigaci贸n b谩sica en C贸rdoba (1960-1990). La construcci贸n del rol del psic贸logo experimental
El presente trabajo presenta una descripci贸n acerca de c贸mo se desarroll贸 el proceso de formaci贸n de una tradici贸n investigativa en C贸rdoba y como se fue delineando las caracter铆sticas del rol del Psic贸logo experimental. El periodo elegido es desde 1960 a 1990, debido a que el inicio del mismo coincide con el egreso de las primeras cohortes luego de la creaci贸n de la carrera en 1956 y el inicio de la profesionalizaci贸n de la disciplina, y finaliza luego del retorno de la democracia, momento en que se reconoce el ejercicio profesional del psic贸logo. El objetivo es conocer c贸mo espacios ajenos a la instituci贸n universitaria, contribuyeron a la formaci贸n de una comunidad cient铆fica que posibilito la invenci贸n de un nuevo rol y la circulaci贸n de las ideas psicol贸gicas. Como conclusi贸n se puede decir que la participaci贸n del psic贸logo en investigaci贸n experimental surge del trabajo interdisciplinario, y que las caracter铆sticas del rol del psic贸logo experimental se fueron tomando de otras 谩reas consolidadas previamente.Fil: Ferrero, Cecilia.

The microbial production of polyphenol oxidase enzyme systems and their application in the treatment of phenolic wastewaters
Phenolic compounds are a group of organic chemicals present in the wastewaters of many synthetic industrial processes. Due to their extreme toxicity to man and animals, and deleterious impact on the environment, a range of techniques exist for the effective treatment and disposal of these pollutants. Biological degradation using microbial enzymes presents a valuable alternative to conventional wastewater treatment systems. This research was therefore initiated to investigate the polyphenol oxidase enzyme system and the feasibility of its application for effluent treatment and studies in organic solvents. The enzyme system is widely distributed in nature, with Agaricus bisporus (the common mushroom) being the best known producer. Biochemical investigations of the enzyme system were therefore carried out using this extract. A screening programme was initiated to identify microbial polyphenol oxidase producers which could be cultured in liquid media, thereby enabling the production of large quantities of enzyme in fermentation systems. Extensive growth optimization and enzyme induction and optimization studies were carried out on selected cultures. A number of good producers were isolated, namely a bacterial culture designated AECI culture no. 26, Streptomyces antibioticus, Streptomyces glaucescens and a manipulated strain, Streptomyces lividans (pIJ702). Enzyme production by Agaricus bisporus mycelia was optimized in deep-liquid culture; enzyme extracts showed high phenol removal efficiencies. Streptomyces antibioticus, Streptomyces glaucescens, Streptomyces lividans (pIJ702) and AECI culture no. 26 whole cells were also investigated for phenol-removing ability in simulated phenolic effluents. The use of whole cells reduces enzyme inactivation and instability due to the protection of the enzyme system within the cell. All cultures showed improved removal efficiencies in phenolic growth media. These results strongly suggest their use for phenol removal in continuous systems

Critical analysis of environmental water quality in South Africa Historic and current trends
South Africa is widely recognised as having an admirable water law, and as being a leader in granting a right to water, in terms of quality and quantity, to the environment. However, the water quality of South Afri-can water resources is deteriorating (eg CSIR 2010, DWA 2011a), alt-hough good water quality management structures, strategies, ap-proaches, programmes, instruments, and tools have been developed and implemented nationally. The research reported on here provides a review of changes in water quality management structures, pro-grammes and approaches over the past two decades, and highlights areas where these need updating, completion or revision. As a com-parative illustration of changes in water quality with time, changes in 11 water quality parameters in two river systems (the Crocodile River in Mpumalanga, which is moderately impacted, and the Olifants River, in Mpumalanga and Limpopo, which is severely impacted) are presented
Use of indigenous riverine invertebrates in applied toxicology and water resource-quality management
The National Water Policy (DWAF, 1997). and the National Water Act (No 36 of 1998)(NWA) provide the legal and management context for the application of results. The law and the policy are founded on the concepts of equity (fairness of access to water and water services) and sustainability (the opportunity to optimally use water resources now and into the future)(NWA, l (l)(xviii)(b)). The concept of sustainability is based on the understanding that on earth water comes packaged in aquatic ecosystems, and that the product, water, is intimately related to and affected by the structure and functioning of these ecosys-tems.(Aquatic ecosystems include rivers, lakes, wetlands, aquifers and estuaries. Impoundments act as artificial lakes connected to river sys-tems.) A key recognition during the development of the policy and the NWA was that" the environment" does not compete with users for re-sources-the environment (in this case aquatic ecosystems) is the re-source. Therefore a key poiicy of DWAF is that vi resource protection in order to achieve sustainable resource use. Resource protection is achieved through the implementation of resource directed measures (RDM) and source directed controls (SDC)
The development of water quality methods within ecological Reserve assessments, and links to environmental flows
In the South African National Water Act (NWA, No 36 of 1998), the eco-logical Reserve is defined as the quality and quantity of water required to ensure appropriate protection of water resources, so as to secure ecologically sustainable development and use. Aquatic ecosystems are recognised as the core location of water resources, and although con-siderable progress has been made in developing methods for quantify-ing environmental flow requirements, this paper describes and discuss-es the first agreed method for quantifying environmental water quality requirements in an ecological Reserve assessment. Integration of flow and water quality is emphasised, and is based on the philosophy that environmental flows should be motivated to provide ecologically im-portant flow-related habitat, or geomorphological function, but should not be motivated to solve water quality problems by dilution. Water qual-ity is multivariate, and not all variables can be considered in an ecologi-cal Reserve assessment, but core water quality variables include: sys-tem variables (salts, dissolved oxygen, turbidity, temperature), nutrients (phosphate, nitrite, nitrate) and toxic substances (those listed in the South African Water Quality Guidelines for Aquatic Ecosystems, includ-ing toxic metal ions, toxic organic substances, and/or substances from a chemical inventory of an effluent or discharge). In addition, biological indicator data (eg SASS data), chlorophyll-a (eg phytoplankton and pe-riphyton data) and toxicity test data may be used. For each variable, a concentration range or response is linked to a class within a water re-source classification system, where classes range from minimally to severely modified
