Teaching Intercultural Citizenship through Intercultural Service Learning in World Language Education

Globalization and internationalization have created a need for dialogue among people of different persuasions in our own societies and beyond. Language teachers can meet this challenge through the concepts of intercultural citizenship and intercultural service learning, renewing emphasis on educational and humanistic aims as well as instrumental. Students in an advanced Spanish course volunteered in a school and a legal center, interacting one-on-one with unaccompanied minors and immigrants fleeing Central America. The evaluation focused on the impact on learners’ understanding of the society in which they live, and perceptions of their own language learning during their work as active citizens. Data from students’ academic blogs and diaries were analyzed thematically. They show a heightened awareness of language competence, as students use their knowledge of Spanish in their voluntary work, and increased intercultural competence in students’ reports on their critical evaluation of perspectives and practices in their own culture and those of others

Intratumor Regulatory Noncytotoxic NK Cells in Patients with Hepatocellular Carcinoma

Previous studies support the role of natural killer (NK) cells in controlling hepatocellular carcinoma (HCC) progression. However, ambiguity remains about the multiplicity and the role of different NK cell subsets, as a pro-oncogenic function has been suggested. We performed phenotypic and functional characterization of NK cells infiltrating HCC, with the corresponding nontumorous tissue and liver from patients undergoing liver resection for colorectal liver metastasis used as controls. We identified a reduced number of NK cells in tumors with higher frequency of CD56(BRIGHT)CD16(-) NK cells associated with higher expression of NKG2A, NKp44, and NKp30 and downregulation of NKG2D. Liver-resident (CXCR6(+)) NK cells were reduced in the tumors where T-bet(hi)Eomes(lo) expression was predominant. HCCs showed higher expression of CD49a with particular enrichment in CD49a(+)Eomes(+) NK cells, a subset typically represented in the decidua and playing a proangiogenic function. Functional analysis showed reduced TNF-alpha production along with impaired cytotoxic capacity that was inversely related to CXCR6(-), T-bet(hi)Eomes(lo), and CD49a(+)Eomes(+) NK cells. In conclusion, we identified a subset of NK cells infiltrating HCC, including non-liver-resident cells that coexpressed CD49a and Eomes and showed reduced cytotoxic potential. This NK cell subset likely plays a regulatory role in proangiogenic function

3D Survey in Extreme Environment: The Case Study of LaetoliHominin Footprints in Tanzania

Many cultural assets are in risky situations and they are destined to disappear. Sometimes problems are caused bythe anthropic component (e.g. wars) or by natural disasters (e.g. earthquakes and landslides). At other times thecause of deterioration is due to the slow and inexorable action of atmospheric agents and other natural factorspresent in extreme areas, where preservation of Cultural Heritage is more complex.This contribution deals with 3D documentation of paleontological excavations in extreme contexts that arecharacterized by unfavorable climatic conditions, limited instrumentation and little time available. In particular, thecontribution is focused on the search for a good working procedure which, despite the problems mentioned above,can lead to valid results in terms of accuracy and precision, so that subsequent scientific studies are notcompromised. The proposed case study concerns the recent discovery of fossil footprints at the Site S in Laetoli,within the Ngorongoro Conservation Area (Tanzania), which is a UNESCO World Heritage Site. With the newdiscovery of Site S it was necessary to implement a 3D survey operative protocol with limited equipment and in avery short time. The 3D models, obtained through the “Structure from Motion” (SfM) technique and topographicsupport, were used to perform morphological and morphometric investigations on the new footprints. Through theanalysis it was possible to estimate height and weight of the footprint makers (hominins of the speciesAustralopithecus afarensis). The collected evidence supports marked intraspecific variation in this species, pointingout the occurrence of a considerable difference in size between sexes and suggesting inferences on reproductivebehavior and social structure of these ancient bipedal hominins.The contribution shows how important is to obtain good 3D documentation, even in extreme environment, in orderto reach reliable results for scientific analysis

An occasional diagnosis of myasthenia gravis - a focus on thymus during cardiac surgery: a case report

<p>Abstract</p> <p>Background</p> <p>Myasthenia gravis, an uncommon autoimmune syndrome, is commonly associated with thymus abnormalities. Thymomatous myasthenia gravis is considered to have worst prognosis and thymectomy can reverse symptoms if precociously performed.</p> <p>Case report</p> <p>We describe a case of a patient who underwent mitral valve repair and was found to have an occasional thymomatous mass during the surgery. A total thymectomy was performed concomitantly to the mitral valve repair.</p> <p>Conclusion</p> <p>The diagnosis of thymomatous myasthenia gravis was confirmed postoperatively. Following the surgery this patient was strictly monitored and at 1-year follow-up a complete stable remission had been successfully achieved.</p

Frozen in the Ashes

Fossil footprints are very useful palaeontological tools. Their features can help to identify their makers and also to infer biological as well as behavioural information. Nearly all the hominin tracks discovered so far are attributed to species of the genus Homo. The only exception is represented by the trackways found in the late 1970s at Laetoli, which are thought to have been made by three Australopithecus afarensis individuals about 3.66 million years ago. We have unearthed and described the footprints of two more individuals at Laetoli, who were moving on the same surface, in the same direction, and probably in the same timespan as the three found in the 1970s, apparently all belonging to a single herd of bipedal hominins walking from south to north. The estimated stature of one of the new individuals (about 1.65 m) exceeds those previously published for Au. afarensis. This evidence supports the existence of marked morphological variation within the species. Considering the bipedal footprints found at Laetoli as a whole, we can hypothesize that the tallest individual may have been the dominant male, the others smaller females and juveniles. Thus, considerable differences may have existed between sexes in these human ancestors, similar to modern gorillas

The future of Cybersecurity in Italy: Strategic focus area

This volume has been created as a continuation of the previous one, with the aim of outlining a set of focus areas and actions that the Italian Nation research community considers essential. The book touches many aspects of cyber security, ranging from the definition of the infrastructure and controls needed to organize cyberdefence to the actions and technologies to be developed to be better protected, from the identification of the main technologies to be defended to the proposal of a set of horizontal actions for training, awareness raising, and risk management

Effect of age, sex and gender on pain sensitivity: A narrative review

© 2017 Eltumi And Tashani. Introduction: An increasing body of literature on sex and gender differences in pain sensitivity has been accumulated in recent years. There is also evidence from epidemiological research that painful conditions are more prevalent in older people. The aim of this narrative review is to critically appraise the relevant literature investigating the presence of age and sex differences in clinical and experimental pain conditions. Methods: A scoping search of the literature identifying relevant peer reviewed articles was conducted on May 2016. Information and evidence from the key articles were narratively described and data was quantitatively synthesised to identify gaps of knowledge in the research literature concerning age and sex differences in pain responses. Results: This critical appraisal of the literature suggests that the results of the experimental and clinical studies regarding age and sex differences in pain contain some contradictions as far as age differences in pain are concerned. While data from the clinical studies are more consistent and seem to point towards the fact that chronic pain prevalence increases in the elderly findings from the experimental studies on the other hand were inconsistent, with pain threshold increasing with age in some studies and decreasing with age in others. Conclusion: There is a need for further research using the latest advanced quantitative sensory testing protocols to measure the function of small nerve fibres that are involved in nociception and pain sensitivity across the human life span. Implications: Findings from these studies should feed into and inform evidence emerging from other types of studies (e.g. brain imaging technique and psychometrics) suggesting that pain in the older humans may have unique characteristics that affect how old patients respond to intervention
