Protocolo de diagnóstico e intervención psicopedagógica: Guía No.3 de diagnóstico rápido; 12-18 años

La adolescencia es una construcción social, por ello, la forma como se la comprende ha cambiado considerablemente con el transcurso de los años y varía también de una región a otra. Hoy en día las políticas de trabajo con la juventud siguen siendo reducidas, mantienen enfoques verticales y adultocentristas que postulan a la adolescencia bajo ópticas discriminatorias: • La adolescencia como una etapa de preparación, de transición a la adultez. Desde esta perspectiva los adolescentes son tratados como sujetos pasivos, con escasa o nula participación en la toma de decisiones y las estrategias de políticas recaen en programas aislados de protección externa. • Por otro lado está la adolescencia como una etapa problema para la sociedad, ésta es la óptica de la criminalización de la juventud. Los jóvenes se visibilizan únicamente cuando transgreden el orden social. La respuesta es el bombardeo aislado, disperso y asistencial de control, de populismo punitivo. En muchas comunidades inclusive, la adolescencia no existe como etapa vital, en medio de la urgencia de incorporar a los adolescentes a trabajar, existe una transición directa de la niñez a la adultez, anulando así un período muy importante en el desarrollo del ser humano. En un esfuerzo por mirar la adolescencia en un marco libre de prejuicios, esta guía parte del análisis de las características generales de la adolescencia, luego brinda información valiosa para evaluar el normal crecimiento y desarrollo psicosexual. Termina poniendo a disposición algunos instrumentos para la evaluación de el/la adolescente: la historia clínica del adolescente (instrumento de valoración integral bio-psico-social) y un test proyectivo de frases incompletas para evaluar el estado emocional.

Stepwise construction of [Os6(CO)18(μ6-P)]-, a hexanuclear osmium cluster monoanion with trigonal-prismatic co-ordination for phosphorus: X-ray crystal structures of [Os6(μ-H)2(CO)20(MeCN)(μ3-PH)] and [PPh3Me][Os6(CO)18(μ6-P)]

Treatment of the labile cluster [Os3(CO)11(MeCN)] with PH3 affords the substituted product [Os3(CO)11(PH3)](1) in high yield. Subsequent reaction of (1) with Na2CO3 in MeOH, followed by acidification, gives the hydrido phosphido cluster [Os3(µ-H)(CO)10(µ-PH2)](2). When (2) is heated to 45–60 °C in the presence of [Os3(CO)11(MeCN)] a hexanuclear complex with the formulation [Os6(µ-H)2(CO)21(µ3-PH)](3) is obtained. If this reaction is repeated using [Os3(CO)10(MeCN)2] instead of [Os3(CO)11(MeCN)], an acetonitrile-containing product, [Os6(µ-H)2(CO)20(MeCN)(µ3-PH)](4), is obtained. An X-ray analysis of (4) shows that two Os3 triangular units are linked by a µ3-phosphinidene ligand, which symmetrically bridges an Os–Os edge of one triangle and is terminally co-ordinated to one Os atom of the second triangle. When (3) is treated with a weak base, such as [N(PPh3)2]Cl or [PPh3Me] Br, deprotonation to the corresponding cluster monoanion [Os6(µ-H)(CO)21(µ3-PH)]–(5) occurs. Treatment of (5) with a weak acid regenerates (3) in quantitative yield. Thermolysis of (3) leads to a closing up of the metal framework, affording the cluster [Os6(µ-H)(CO)18(µ6-P)], which readily deprotonates to give the anion [Os6(CO)18(µ6-P)]–(7) in the presence of [N(PPh3)2] Cl or [PPh3Me]Br. The same anion (7) may also be obtained by direct thermolysis of (5). An X-ray analysis of the [PPh3Me]+ salt of (7) confirms that the phosphorus occupies an interstitial site in a trigonal-prismatic hexaosmium framework, and co-ordinates to all six metal atoms with an average Os–P distance of 2.31 (1)Å. Proton and 31P n.m.r. data on all the new clusters are presented, and the position of the phosphorus resonance in the 31P n.m.r. spectrum is related to the changes in the environment of the phosphorus atom.

• Chronic Wasting Disease Update: Wisconsin, Minnesota, South Dakota, Colorado; National CWD Management – USDA & USDI National Plan for Assisting States, Federal Agencies, and Tribes in Managing Chronic Wasting Disease in Free-ranging and Captive Cervids • West Nile virus (WNV) reaches the Pacific coast • West Nile Virus in Blue Jays • Idaho Brucellosis Linked to Wildlife: All of the epidemiological and laboratory information clearly indicates that brucellosis-infected elk transmitted the disease to the cattle herd. • Tularemia caused a die-off of captured wild prairie dogs this summer at a Texas commercial exotic animal facility that distributes the animals for sale as pets. • Raptors can acquire avian vacuolar myelinopathy (AVM) via ingestion of other affected birds. • House Finch Mycoplasmosis: bacterial eye disease of house finches • Raccoon Rabies report • Toxoplasmosis – The newest finding regarding sea otters in California is the importance of toxoplasmosis as a mortality factor. Toxoplasma gondii is a protozoan parasite that can invade visceral organs and the central nervous system to cause acute, disseminated tissue necrosis and fatal meningoencephalitis in susceptible animals. In recent years, 36% of dead sea otters examined have been infected. Another tissue-invading protozoan, Sarcocystis neurona, also was found in 4% of the otters. • Recovery of remnant populations of the endangered black-footed ferret have been hampered by sylvatic plague, which is caused by the bacterium Yersinia pestis. • Dr. Samantha Gibbs received the Wildlife Disease Association’s Student Research Recognition Award. Dr. Cynthia Tate was selected by the American Association of Veterinary Parasitologists to receive the Best Student Presentation Award. Dr. Andrea Varela won second place in the Student Presentation Award for her presentation at the meeting of the American Association Veterinary Parasitologists. Mr. Michael Yabsley received the Wildlife Disease Association Student Scholarship and the S.A. Ewing Vectorborne Parasitology Award from the University of Georgia’s College of Veterinary Medicine.

Kommentierte Bibliographie zur Archäologie Rheinhessens, Stand: 18.3.2010

Die Bibliographie soll nicht nur dem in und über Rheinhessen arbeitenden Ar-chäologen ein Hilfsmittel sein, sondern wendet sich ganz besonders an archäologisch interessierte Heimatforscher. Sie ist nach Orten alphabetisch sortiert (von einigen Abweichungen wegen Eingemeindungen und Zusammenlegungen abgesehen). Es finden sich die den Verfassern bekannt gewordenen Publikationen (Monographien, Aufsätze, Katalogbeiträge etc.) zum jeweiligen Ort; wo aus dem Titel nicht klar hervorgeht, welchen Inhalts der bibliographierte Beitrag ist, wurde dies in eckigen Klammern angefügt. Mitunter wurden auch weitere Kommentare angebracht.rnDie Bibliographie ist ein laufendes Projekt; Aktualisierungen durch Aufnahme von Neuerscheinungen sowie Erfassen älterer Literatur werden als neue Versionen an dieser Stelle eingestellt werden.
