A forensic anthropological investigation of skeletal remains recovered from a 1000 year old archaeological site in North Western Namibia

Human and faunal skeletal remains were found scattered around the base of a talus cone at the bottom of a 30 metre sinkhole at Khoraxa-ams northwest of the Central Namib Desert. Subsequent dating of the site indicated that the remains had been deposited in the cavern in the order of a thousand years ago. The aim of this study was to examine skeletal remains recovered from the site and draw possible conclusions as to who they were and the circumstances surrounding their deposition in the cave. A forensic analytical approach was utilized to uncover the evidence, allowing us to manage the site as a 'crime scene.' This approach included determining the MNI, constructing a demographic profile and analysing post-mortem preservation as well as posing questions vital to forensic investigations including ante-mortem features that could lead to the ethnic identification of unknown individuals and the peri-mortem circumstances surrounding the deposition of the remains. Sixteen individuals, based on cranial bone representation were identified in the sample, consisting of only adult individuals with the exception of one sub-adult, and a male to female ratio of roughly 1:1. The people of Khoraxa-ams were of Negroid ancestry, consumed a mixed diet of gathered and agricultural foods, were in fairly good health at the time of their death, showed signs of involvement in low-impact labour and practiced dental modification. Their most likely identity, based on these biological markers, lifestyle observations and cultural practices, is a group similar or ancestral to the modern Herero of Namibia. The exact nature and circumstance surrounding the cause of death is unknown. Based on the extent of skeletal injuries, it is likely that they received peri-mortem blunt force trauma and post-mortem trauma after death by being dropped into the 30 metre cave. It is speculated, given the demographic profile of women and children presenting with more severe blunt force trauma, the lack of defence wounds and the fact the individuals were dead before being dropped in the cave, that the site at Khoraxa-ams represents an execution location, though no secure evidence exists to support this theory. The forensic approach to this study has enabled the identification of otherwise unknown archaeological remains, and has also provided insight into a period of Namibian history where relatively little is known

Sexualität und Autismus : Die Bedeutung von Kommunikation und Sprache für die sexuelle Entwicklung

Auch Menschen mit Autismus haben sexuelle Bedürfnisse. Aufgrund ihrer spezifischen Wahrnehmung und ihrer abweichenden sozio-kommunikativen Fähigkeit erleben Autist_innen sich und ihre Umwelt jedoch anders als Menschen ohne Autismus. Wichtig für die sexuelle Entwicklung ist jedoch eine gelungene zwischenmenschliche Kommunikation. Um an sexuellen Entwicklungsprozessen teilhaben zu können, benötigen autistische Menschen deshalb mitunter eine sehr intensive und zielgerichtete Unterstützung. Der Schwerpunkt des vorliegenden Buches liegt unter besonderer Berücksichtigung autismusspezifischer kommunikativer Fähigkeiten auf der psychosexuellen Entwicklung von Menschen aus dem Autismus-Spektrum. Die Autorin beleuchtet die Bedeutung von Kommunikation und Sprache und beschreibt, wie Veränderungen in diesem Bereich die Entwicklungsprozesse nachhaltig beeinflussen können. Dabei wird der Fokus auf einzelne Methoden der Unterstützten Kommunikation und deren positive Wirkung auf Sozialisationsprozesse der Sexualität gelegt. Sowohl Chancen dieser Methoden als auch mögliche Anwendungsfelder werden aufgezeigt und kritisch diskutiert.Sexuality and Autism: The Significance of Communication and Language for Sexual Development: People with autism too have sexual needs. But due to their specific perception and differing socio-communicative ability autistic people experience themselves and their environment differently than people without autism. However, successful interpersonal communication is important for sexual development. Therefore, autistic people sometimes need intense and well mapped-out assistance in order to be able to participate in sexual development processes. Centering on the psycho-sexual development of people from the autism spectrum, this book pays particular attention to autism-specific communication skills. It highlights the significance of communication and language and examines how modifications in this realm can have lasting impact on the development processes. The focus is placed on individual methods of Augmentative and Alternative Communication and their positive effects on socialization processes of sexuality. Both the chances offered by these methods as well as the possible areas of their application are demonstrated and critically discussed

Producción de hidrógeno a partir de energía solar. Panorama en Colombia

Power generation from renewable sources like the sun; represents an opportunity to reduce the emission of greenhouse gases, which are responsible for the acceleration of climate change in recent years. In turn, hydrogen is considered an ideal energy carrier for renewable energy, which will allow the implementation of a new model of energy supply, interest to countries like Colombia, where in the medium and long term, solar energy widely available, promote energy independence, ensure supply throughout the country and provide both environmental and social welfare in the energy field.La generación de energía a partir de fuentes renovables como el sol, representa una oportunidad para reducir la emisión de gases de efecto invernadero, los cuales han sido los responsables de la aceleración del cambio climático, en los últimos años. A su vez, el hidrógeno es considerado el vector o gestor energético ideal para las energías de tipo renovables, que puede facilitar la implementación de un nuevo modelo de suministro energético, para países como Colombia, que en un mediano y largo plazo, la energía solar ampliamente disponible, promueva la independencia energética, garantice el suministro en todo el territorio y aporte tanto bienestar ambiental como social en materia energética
