From security to precariousness: The case of the Greek mass media sector in neoliberal times

Το άρθρο εστιάζει στον τρόπο με τον οποίο πρώην εργαζόμενοι στα Μέσα Mαζικής Ενημέρωσης βίωσαν το πέρασμα από μια ασφαλή εργασιακήσχέση στην επισφάλεια. Βασίζεται σε εθνογραφική έρευνα δεκατεσσάρων μηνών (Αύγουστος 2012 – Οκτώβριος 2013) στον τηλεοπτικό σταθμό ALTER TV. Επιπλέον διενεργήθηκαν δεκαπέντε ημι-δομημένες συνεντεύξεις με εργαζόμενους. Στα συμπεράσματα του άρθρου εξετάζεται η διαμόρφωση ενός νέου τύπου εργασιακού υποκειμένου μέσα από: α) την επανεπινόηση ξεχασμένων οικονομικών διαδικασιών, β) την κινητοποίηση κάθε κοινωνικού δικτύου για την αντιμετώπιση της επισφάλειας και γ) την κριτική απέναντι στο λεγόμενο «παλιομοδίτικο συνδικαλισμό».The paper focuses on the way ex-mass media employees experienced a dramatic passage from safe employment to a precarious condition.It is based on fourteen months ethnographic research (August 2012 to October 2013) in the closing premises of the ALTER TV Channel. In addition, fifteen semi–structured interviews were conducted with employees. In the concluding remarks a new type of working subject is questioned through a) the ‘reinvention’ of forgotten economic processes, b) the motivation of any social network to cope with precariousness and c) the critique of the so called ‘old fashioned’ syndicalism

An unusual case of intestinal obstruction by volvulus of Meckel’s diverticulum in a 10-year-old child: a case report

Intestinal obstruction, gastrointestinal haemorrhage, adherence, intussusception, acute diverticulitis and rarely malignity are the most common complications of Meckel’s diverticulum in children. Reported mechanism of intestinal obstruction in Meckel’s diverticulum include invagination, adherence and volvulus. Obstructive ileum caused by volvulus of Meckel’s diverticilum is not a very frequent medical condition. Here we describe a case of intestinal obstruction caused by volvulus of non-inflamed Meckel’s diverticulum in a 10-year-old child. Considering the potentially life-threatening obstructive ileum in cases of children with deteriorating clinical picture, surgical exploration should not be delayed

A rare case of pontocerebellar hypoplasia type 1B with literature review

A full-term female newborn was transferred to our neonatal intensive care unit (NICU) on day two of life for hypotonia. Physical examination was significant for overriding sutures, displaced small anterior fontanelle, axial hypotonia, extremity hypertonia, and slow deep tendon reflexes. She was also noted to have stridor with crying but had unlabored breathing without oxygen requirements and a normal heart examination. A brain magnetic resonance imaging (MRI) showed a large cisterna magna and cerebellar hypoplasia with the majority of the cerebellar vermis present, suggesting a possible Dandy-Walker variant (cerebellar vermis hypoplasia). Head computed tomography showed areas of close approximation of coronal sutures and no synostosis. During the NICU stay, our patient was evaluated by Pediatric Neurology who recommended a chromosomal microarray which returned normal. The patient also had some difficulty feeding initially, but she was able to feed efficiently and gain weight by the time of discharge. After discharge from NICU, her neurological status steadily declined, resulting in poor motor function and poor suck despite regular physical therapy, occupational therapy, and speech therapy. By three months of age, she developed failure to thrive and was admitted to the hospital for evaluation of the cause. Her neurological examination showed worsening of her axial hypotonia with very little movement in the upper extremities and hypertonia in the lower extremities. She had a weak suck with the inability to form a good seal on the nipple. A new heart murmur was noted and an echocardiogram showed a moderate-to-large atrial septal defect. A modified barium swallow study showed severe dysphagia for which she required gastrostomy tube placement for feeding. At follow-up with Neurology, she was noted to have progressive microcephaly, profound hypotonia, areflexia, and nystagmus. A second MRI showed worsening atrophy and increasing ventriculomegaly. By nine months of age, she developed respiratory failure, required a tracheostomy, and remained ventilator-dependent. Genetics was then consulted and recommended a brain malformation genetic panel. The patient was found to be heterozygous for two pathogenic variants in th

Skarn rico em ferro associado ao sienito linda vista, segmento anicuns-itaberaí do arco magmático Goiás : mineralogia, metassomatismo e geoquímica isotópica

Dissertação (mestrado) — Universidade de Brasília, Instituto de Geociências, Programa de Pós-Graduação em Geologia, 2021.Skarns são um tipo de rocha definida essencialmente por sua mineralogia, em geral, predominantemente calcissilicática como granada e piroxênio. Estão presentes em todos os continentes e em rochas de quase todas as idades. Skarns são relacionados a processos metassomáticos, podendo estar envolvido com grande diversidade de fluidos (magmático, metamórfico, meteórico e de origem marinha). O Skarn Linda Vista, localizado no Orógeno Brasília, representa uma ocorrência inédita no contexto do Arco Magmático de Goiás, constituindo um modelo clássico de skarn, com sua gênese relacionada a um plutón (Sienito Linda Vista) tardi-tectônico (649 ± 3.2 Ma) em meio a encaixantes (principalmente mármores e magnetita-quartzitos) da sequência metavulcanossedimentar Anicuns-Itaberaí. O contato entre plutón e encaixantes desenvolve uma série de processos isoquímicos e metassomáticos, com destaque para o enriquecimento em Ferro no interior da intrusão, descrevendo um endoskarn. O Skarn Linda Vista é, essencialmente, descrito como um endoskarn rico em ferro com associação característica de magnetita-clinopiroxênio (aegirina-augita). Contudo, há zonas discretas, próximas ao contato com mármores, onde se desenvolvem rochas ricas em flogopita e rochas calcissilicáticas (skarnóide calcissilicático). Observações petrográficas e análises de química mineral permitiram discriminar estágios relacionados à formação do skarn. Foram descritos 3 principais estágios: (1) estágio progressivo isoquímico, onde não há mistura composicional das rochas em contato, marcada pela formação de tremolita em mármores dolomíticos recristalizados; (2) estágio progressivo metassomático, representado no endoskarn pela formação em larga escala pela associação magnetita-clinopiroxênio e formação de rochas ricas em flogopita na zona de contao com mármores; (3) estágio retrógrado, onde há substituição das mineralogias anteriores por fases hidratadas de baixa temperatura, com riebeckita, clorita e martitização da magnetita no endoskarn, assim como desenvolvimento das assembleias calcissilicáticas associadas a sulfetação na zona de contato com mármores. As rochas do endoskarn fornecem claras evidências de um intenso Fe-metassomatismo com substituição das assembleias originalmente ígneas do Sienito Linda Vista pela associação magnetita-clinopiroxênio. A origem desse ferro pode ser explicada pela possível solubilização dos magnetita-quartzito encaixantes a intrusão atráves de fluidos ricos em HCl, que complexam o ferro sob a forma de FeCl2. Dados isotópicos de Carbono e Oxigênio também revelam importantes aspectos para modelar o contato entre sienito e mármores, de acordo com curvas de Batch (sistema fechado) e Rayleigh (sistema aberto), para devolatilização de CO2 no estágio progressivo isoquímico, onde predomina as feições de metamorfismo de contato por meio de decomposição de calcita e reações calcissilicáticas em alta temperatura.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) e Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq).Skarns are rocks defined essentially by their mineralogy, in general, predominantly calcsilicate minerals as Ca-rich garnet and pyroxene. Moreover, skarns are largely confined across all continents and in rocks of almost all ages. These occurrences are related to metasomatic processes and may be involved with a great diversity of fluids (magmatic, metamorphic, meteoric, and marine sources). Linda Vista Skarn, located in the Brasília Orogen, represents an unprecedented occurrence in the context of the Goiás Magmatic Arc, constituting a classic skarn model, with its genesis related to a post-tectonic intrusion (Linda Vista Syenite; 649 ± 3.2 Ma) into the basement (mainly marbles and magnetite-quartzites of the Anicuns-Itaberaí metavolcano-sedimentary sequence). The contact between pluton and basement rocks develops a series of isochemical and metasomatic processes with emphasis on the iron enrichment inside the intrusion, describing an endoskarn. Linda Vista occurrence is essentially described as an iron-rich endoskarn with a typical magnetite-clinopyroxene association (aegirine-augite). However, discrete zones are observed close to the contact with marbles, where phlogopite-rich rocks and calc-silicate rocks (hornblende-epidote calc-silicate) develop. Petrographic observations and mineral chemistry analyses allowed to discriminate three main stages related to skarn formation: (1) Isochemical progressive stage, where there is no compositional mixing of rocks in contact, characterized by the neoformed tremolite in recrystallized dolomitic marble; (2) Progressive metasomatic stage, represented in the endoskarn by the large scale formation of the magnetite-clinopyroxene association and the formation of phlogopite-rich rocks in the marble contact zone; (3) Retrograde stage, where previous mineralogies are replaced by hydrated low-temperature phases, with riebeckite, chlorite, and magnetite martitization in the endoskarn, as well as the development of calc-silicate assemblages associated with sulfidation in the marble contact zone. The endoskarn rocks provide clear evidence of an intense Fe-metasomatism with replacement of the originally igneous assemblages of Linda Vista Syenite by the magnetiteclinopyroxene association. This iron origin may be explained by the possible solubilization of the magnetite-quartzite basement rocks through HCl-rich fluids, which triggers the complexation of iron in the FeCl2 form. Carbon and Oxygen isotopic data also reveal important aspects to model the contact between syenite and marbles, according to Batch (closed system) and Rayleigh (open system) curves for CO2 devolatilization in the isochemical progressive stage, where contact metamorphism features predominate through calcite decomposition and calc-silicate hightemperature reactions

Redefining Success: How Tribal Colleges and Universities Build Nations, Strengthen Sovereignty, and Persevere Through Challenges

After enduring nearly 400 years of higher education efforts driven by religious indoctrination and forced assimilation, in 1968 Diné College opened its doors as the first Tribally controlled post-secondary institution, marking a new era of self-determination for Native American students. Since then, Tribal Colleges and Universities (TCUs) have grown to include 37 institutions, serving over 28,000 students and are actively working to revitalize Native languages and culture, promote Tribal sovereignty and further economic growth aligned with Tribal values in the communities they serve. These remarkable institutions often go unrecognized for their achievements, and most remain unjustly underfunded in spite of the fact that their work redefines the valuable impact that higher institutions can have within their local communities.We hope to support the Tribal Colleges and Universities, their membership association, the American Indian Higher Education Consortium (AIHEC), and their non-profit support organization, the American Indian College Fund (College Fund), by reframing the conversation and reminding critics that TCUs were not created to serve the same purpose as other higher education institutions. Rather, TCUs were created for the purpose of supporting Tribal Nation-building after Indigenous cultures endured generations of cultural and economic deterioration. This report offers an alternative story of success that looks beyond quantifiable measures to focus more deeply on how these schools meet this mission. We hope to draw additional attention to the many challenges that TCUs face, such as underfunding and operating in geographically remote areas, and outline the strategies they have employed to find success in spite of these challenges. Lastly, we make recommendations to help policy makers and institutional leaders support and strengthen these institutions and the students they serve

Anastomotic loop between common hepatic artery and gastroduodenal artery in coexistence with an aberrant right hepatic artery

Anatomical variations of the hepatic arteries are not uncommon. The anomalous hepatic arterial supply is of paramount importance in hepatobiliary, pancreatic or liver transplantation and in laparoscopic surgery. We describe an unusual case of a 66-year-old Greek male cadaver, where a rare anastomosis (in the form of an enlarged arterial loop, 4.84 mm in diameter) between the common hepatic artery (6.42 mm) and the gastroduodenal artery (GDA) (4.82 mm) coexisted with an aberrant right hepatic artery (ARHA) (6.38 mm) originating from the superior mesenteric artery. The proper hepatic artery was absent. The ARHA followed a route posterior to the portal vein and the common hepatic duct, entering the liver and supplying the right hepatic segment. A hypoplastic right gastric artery emanated from the GDA. Our case report highlights the combined variations of hepatic arteries and possible anastomoses emphasizing that a thorough knowledge of the classic and variable hepatic arterial anatomy are mandatory for surgeons and radiologists performing hepatic surgery and arteriography to avoid potential iatrogenic injuries in hepatobiliary and pancreas area and further medico-legal implications
