Le variazioni anatomiche: La vera immagine dell'anatomia dell'uomo

La studio dell’Anatomia umana presenta una varietà di sfaccettature, che sono alla base della reale comprensione del corpo umano; ovvero la vera anatomia non è quella rappresentata nei testi ma quella che appare durante la dissezione o nelle più sofisticate analisi di immagine. Lo scopo di questa tesi è stato quello di rivisitare alcune situazioni vascolari che possono andare incontro a variazioni e cercare di comprendere, anche con l’aiuto della bibliografia, se tali variazioni possono essere causa o epifenomeni di patologie a carico delle arterie affette dalle variazioni stesse o di territori da esse dipendenti per l’afflusso sanguigno. E’ stata condotta una analisi su preparati cadaverici in particolare in tre distretti: a) addome e tripode celiaco/mesenterica superiore; b) circolo cerebrale; d) orco aortico.

La sanità mediata: il rapporto medico-paziente dentro e fuori lo schermo televisivo

L’obiettivo di questa tesi è rilevare se e quanto i medical dramas abbiano contribuito a ridefinire conoscenze, aspettative e pratiche dei telespettatori/pazienti rispetto a questioni concernenti la salute e il loro ruolo all’interno della relazione medico-paziente. Grazie ad un lavoro di campo, fatto di questionari e interviste con utenti, operatori della sanità di Centro e Nord Italia e studenti di Medicina, sono state poi registrate le modalità di interazione che i protagonisti della scena della cura dichiarano di sperimentare quotidianamente. Ciò ha permesso di rendere conto delle trasformazioni più recenti della professione medica e di come viene elaborato oggi il sapere sulla malattia da parte dei soggetti implicati, fra tecnicismi, atteggiamenti difensivi, sfiducia e affidamento. La tesi restituisce anche alcune modalità sperimentali di interazione fra pazienti e medici, messe in atto in contesti locali, che testimoniano l’esigenza di approdare a un sapere partecipato delle relazioni di cura. Infine, raccogliendo la sfida posta dalle medical humanities, immagina un utilizzo del medical drama nella formazione degli studenti di medicina per l’apprendimento di competenze narrative necessarie ad una pratica medica più umana e efficace.

Traduzione per il web nelle istituzioni europee. Proposta di localizzazione di una sezione di sito della dg azione per il clima

The aim of this dissertation is to provide an adequate translation from English into Italian of a section of the European Commission's site, concerning an environmental policy tool whose aim is to reduce the EU greenhouse gas emissions, the Emissions Trading System. The main reason behind this choice was the intention to combine a personal interest in the domain of sustainability development with the desire to delve deeper into the knowledge of the different aspects involved in the localisation process. I also had the possibility to combine these two with my interest in the universe of the European Union. I therefore worked on the particular language of this supranational organisation and for this reason I had the opportunity to experience a very stimulating work placement at the Directorate-General for Translation in Brussels. However, the choice of the text was personal and the translation is not intended for publication. The work is divided into six chapters. In the first chapter the text is contextualised within the framework of the EU, and its legislation on multilingualism. This has consequences on the languages that are used by the drafters of the official documents and on the languages used by translators. The text originates from those documents, but it needs to be adapted to different receivers. The second chapter investigates the process of website localisation. The third chapter offers an analysis of the source text and of the prospective target text. In the fourth chapter the resources created and used for the translation of the text are described. A comparison is made between the resources of the translation service of the European Commission and the ones created specifically for this project: a translation memory, exploited through the use of a CAT tool, and two corpora. The fifth chapter contains the actual translation, side-by-side with the source text, while the sixth one provides a comment on the translation strategies.

Does the Presence of a Learning Disability Elicit a Stigmatization?

Aims: To determine whether or not a Learning Disability(LD) label leads to stigmatization. Study Design: This research used a 2(sex of participant) x 2(LD label)x 2 (Sex of stimulus person) factorial design. Place and Duration of Study: Bucknell University, between October 2010 and April 2011. Methodology: Sample: We included 200 participants (137 women and 63 men, ranging in age from 18 – 75 years, M = 26.41. Participants rated the stimulus individual on 27 personality traits, 8 Life success measures, and the Big-5 personality dimensions. Also, participants completed a Social Desirability measure. Results: A MANOVA revealed a main effect for the Learning Disability description, F(6, 185) = 6.41 p< .0001, eta2 = .17,for the Big-5 personality dimensions, Emotional Stability, F(1, 185) = 13.39, p < .001, eta2 = .066, and Openness to Experiences F(1,185) = 7.12, p< .008, eta2 = .036.Stimulus individuals described as having a learning disability were perceived as being less emotionally stable and more open to experiences than those described as not having a learning disability. Another MANOVA revealed a main effect for having a disability or not, F(8, 183) = 4.29, p< .0001, eta2 = .158, for the Life Success items, Attractiveness, F(1, 198) = 16.63, p< .0001, eta2 = .080, and Future Success,F(1, 198) = 4.57, p< .034, eta2 = .023. Stimulus individuals described as having a learning disability were perceived as being less attractive and with less potential for success than those described as not having a learning disability. Conclusion: The results of this research provide evidence that a bias exists toward those who have learning disabilities. The mere presence of an LD label had the ability to cause a differential perception of those with LDs and those without LDs.

Learning My Lessons: Research, Rehearsal, and Reflection on the Greats

A successful actor often requires a specific acting method or style to enhance their performance. Through theatrical research, rehearsal and performance, an actor can narrow down their seemingly endless search for the most productive methodology. By researching, studying, and applying the methods of Constantin Stanislavski, Stella Adler,and Tadashi Suzuki to my rehearsal process, I have found my most effective acting style: Stella Adler?s method. I utilize this acting method during the performance period of my early professional acting career. Experimental research for this thesis was completed inthe studio. I applied each of the three aforementioned methods to a dramatic/classical monologue. The results I gathered helped me to decide upon Adler?s methodology to carry with me through my upcoming professional auditions and career. From casting resulting from the auditions, I will employ the methodology to my professional work asan actress. Each acting teacher has provided the performance world with a new way to experience their stage time. The methods are unique and enable the actor to find the most dynamic performance through engaging technical skill.

Virologic failure and second-line antiretroviral therapy in children in South Africa--the IeDEA Southern Africa collaboration

Background: With expanding pediatric antiretroviral therapy (ART) access, children will begin to experience treatment failure and require second-line therapy. We evaluated the probability and determinants of virologic failure and switching in children in South Africa. Methods: Pooled analysis of routine individual data from children who initiated ART in 7 South African treatment programs with 6-monthly viral load and CD4 monitoring produced Kaplan-Meier estimates of probability of virologic failure (2 consecutive unsuppressed viral loads with the second being >1000 copies/mL, after ≥24 weeks of therapy) and switch to second-line. Cox-proportional hazards models stratified by program were used to determine predictors of these outcomes. Results: The 3-year probability of virologic failure among 5485 children was 19.3% (95% confidence interval: 17.6 to 21.1). Use of nevirapine or ritonavir alone in the initial regimen (compared with efavirenz) and exposure to prevention of mother to child transmission regimens were independently associated with failure [adjusted hazard ratios (95% confidence interval): 1.77 (1.11 to 2.83), 2.39 (1.57 to 3.64) and 1.40 (1.02 to 1.92), respectively]. Among 252 children with ≥1 year follow-up after failure, 38% were switched to second-line. Median (interquartile range) months between failure and switch was 5.7 (2.9-11.0). Conclusions: Triple ART based on nevirapine or ritonavir as a single protease inhibitor seems to be associated with a higher risk of virologic failure. A low proportion of virologically failing children were switched.

SEARCHING FOR HOPE IN SAMUEL BECKETT, EDWARD ALBEE, AND SAM SHEPARD

Reading absurdist plays as hopeful is rare because they are filled with portrayals of horror and despair. However, the tragedy of these plays can allow the audience to experience an atypical kind of hope, often during the final moments of the play. Though the conclusions of the plays are usually ambiguous, this ambiguity and lack of resolutiondoes not preclude hope. The characters persist through their suffering and react in ways that can allow a hopeful affect on the audience. The three absurdist playwrights, Samuel Beckett, Edward Albee, and Sam Shepard, express differing views of the tragic nature of the human condition. However, persistent through all of their work is the ability to view tragedy as having a hopeful affect on the audience. Though the plays do not necessitate a reading of hopefulness, their plays do not preclude this. These absurdist plays do not force the audience into despair, but instead leave open the option of experiencing an expectation and determination for life.

Predictors of Clinical Outcomes in Patients With Severe Aortic Stenosis Undergoing TAVI: A Multistate Analysis

Patients with severe aortic stenosis at increased surgical risk continue to experience compromised long-term survival despite successful transcatheter aortic valve implantation. We used time-related pathways in a multistate analysis to identify predictors of adverse long-term outcome in patients who underwent transcatheter aortic valve implantation.

Toward a Global Organic Culture: Ethnographic Perspectives on Wwoofing Practices in Peru and New Zealand

In this thesis, I explore the meaning behind sustainable living among organic farmers and their families in two countries. It is based on original, ethnographic research that I conducted in New Zealand in fall 2012 and Peru in summer 2012 with support from the Department of Sociology and Anthropology Meerwarth Undergraduate Research Fund. In carrying out my research I relied on participant-observation, semi-structured interviews, focus groups, and writing ethnographic fieldnotes. Drawing on contemporary scholarship in the anthropology of food and the environment, my thesis contributes to cross-culturally understandings of sustainability and local and global foodways. Specifically, I will interpret the meaning and significance of my informants’ decision to live sustainably through their participation in wwoofing. The global network of wwoofing aims to connect volunteers interested in learning about organic farming techniques with farmers looking for labor assistance. Volunteers exchange work for food, accommodation, knowledge, and experience. As a method of farming and a subjective ideological orientation, this global movement allows travelers from all over the world to experience organic lifestyles worldwide. In my thesis, I connect my experiences of organic living in Peru and New Zealand. In comparing wwoofing practices in these two field sites, I argue that despite observable differences in organic practices, a global organic culture is emerging. Here I highlight some shared features of this global organic culture, such as food authenticity, sustainability of the earth, and a personal connection of individuals to the land. The global organic culture emphasizes a conscious awareness of what is going into one’s body and why. Using food as an expression of values and beliefs, organic farmers reconnect to the land and their food in attempts to construct an alternative identity. By focusing on food authenticity, my informants develop vast relationships with the land, which shapes their identity and creates new forms of self-enhancement.

Mother-Child Spiritual Discourse: A Mixed Methods Study

Parents and children, starting at very young ages, discuss religious and spiritual issues¿where we come from, what happens to us after we die, is there a God, and so on. Unfortunately, few studies have analyzed the content and structure of parent-child conversation about religion and spirituality (Boyatzis & Janicki, 2003; Dollahite & Thatcher, 2009), and most studies have relied on self-report with no direct observation. The current study examined mother-child (M-C) spiritual discourse to learn about its content, structure, and frequency through a survey inventory in combination with direct video observation using a novel structured task. We also analyzed how mothers¿ religiosity along several major dimensions related to their communication behaviors within both methods. Mothers (N = 39, M age = 40) of children aged 3-12 completed a survey packet on M-C spiritual discourse and standard measures of mothers¿ religious fundamentalism, intrinsic religiosity, sanctification of parenting (how much the mother saw herself as doing God¿s work as a parent), and a new measure of parental openness to children¿s spirituality. Then, in a structured task in our lab, mothers (N = 33) and children (M age = 7.33) watched a short film or read a short book that explored death in an age-appropriate manner and then engaged in a videotaped conversation about the movie or book and their religious or spiritual beliefs. Frequency of M-C spiritual discourse was positively related to mothers¿ religious fundamentalism (r = .71, p = .00), intrinsic religiosity (r = .77, p = .00), and sanctification of parenting (r = .79, p = .00), but, surprisingly, was inversely related to mothers¿ v openness to child¿s spirituality (r = -.52, p = .00). Survey data showed that the two most common topics discussed were God (once a week) and religion as it relates to moral issues (once a week). According to mothers their children¿s most common method of initiating spiritual discourse was to repeat what he or she has heard parents or family say about religious issues (M = 2.97; once a week); mothers¿ most common method was to describe their own religious/spiritual beliefs (M = 2.92). Spiritual discourse most commonly occurred either at bedtime or mealtime as reported by 26% of mothers, with the most common triggers reported as daily routine/random thoughts (once a week) and observations of nature (once a week). Mothers¿ most important goals for spiritual discourse were to let their children know that they love them (M = 3.72; very important) and to help them become a good and moral person (M = 3.67; very important). A regression model showed that significant variance in frequency of mother-child spiritual discourse (R2 = .84, p = .00) was predicted by the mothers¿ importance of goals during discourse (ß = 0.46, p = .00), frequency that the mother¿s spirituality was deepened through spiritual discourse (ß = 0.39, p = .00), and the mother¿s fundamentalism (ß = 0.20, p = .05). In a separate regression, the mother¿s comfort in the structured task (ß = 0.70, p = .00), and the number of open-ended questions she asked (ß = -0.26, p = .03) predicted the reciprocity between mother and child (R2 = .62, p = .00). In addition, the mother¿s age (ß = 0.22, p = .059) and comfort during the task (ß = 0.73, p = .00) predicted the child¿s engagement within the structured task. Other findings and theoretical and methodological implications will be discussed.

Feelings of revenge, retaliation motive, and posttraumatic stress reactions in crime victims

Individuals with posttraumatic stress disorder (PTSD) are often said to experience strong feelings of revenge. However, there is a need for confirmatory empirical studies. Therefore, in a study of 174 victims of violent crimes, the relation between feelings of revenge and posttraumatic stress reactions was investigated. Feelings of revenge were correlated with intrusion and hyperarousal but not with avoidance. Feelings of revenge explained incremental variance of intrusion and hyperarousalwhen the variance explained by victimological variables was controlled. The retaliation motive implied in feelings of revenge did not account for the relation between feelings of revenge and posttraumatic stress reactions. However, the relation was moderated by the time since victimization. Therefore, feelings of revenge must presumably be regarded as a maladaptive coping reaction to experienced injustice, but not in the first period after victimization.

Design of a lab scale direct-filtration system and its application in process lab

The Environmental Process and Simulation Center (EPSC) at Michigan Technological University started accommodating laboratories for an Environmental Engineering senior level class CEE 4509 Environmental Process and Simulation Laboratory since 2004. Even though the five units that exist in EPSC provide the students opportunities to have hands-on experiences with a wide range of water/wastewater treatment technologies, a key module was still missing for the student to experience a full cycle of treatment. This project fabricated a direct-filtration pilot system in EPSC and generated a laboratory manual for education purpose. Engineering applications such as clean bed head loss calculation, backwash flowrate determination, multimedia density calculation and run length prediction are included in the laboratory manual. The system was tested for one semester and modifications have been made both to the direct filtration unit and the laboratory manual. Future work is also proposed to further refine the module.

Perceptions of water conditions and management in the Sonora River Basin, Sonora, Mexico

The effects of climate change are expected to be very severe in arid regions. The Sonora River Basin, in the northwestern state of Sonora, Mexico, is likely to be severely affected. Some of the anticipated effects include precipitation variability, intense storm events, higher overall temperatures, and less available water. In addition, population in Sonora, specifically the capital city of Hermosillo, is increasing at a 1.5% rate and current populations are near 700,000. With the reduction in water availability and an increase in population, Sonora, Mexico is expected to experience severe water resource issues in the near future. In anticipation of these changes, research is being conducted in an attempt to improve water management in the Sonora River Basin, located in the northwestern part of Sonora. This research involves participatory modeling techniques designed to increase water manager awareness of hydrological models and their use as integrative tools for water resource management. This study was conducted as preliminary research for the participatory modeling grant in order to gather useful information on the population being studied. This thesis presents research from thirty-four in-depth interviews with water managers, citizens, and agricultural producers in Sonora, Mexico. Data was collected on perceptions of water quantity and quality in the basin, thoughts on current water management practices, perceptions of climate change and its management, experience with, knowledge of, and trust in hydrological models as water management tools. Results showed that the majority of interviewees thought there was not enough water to satisfy their daily needs. Most respondents also agreed that the water available was of good quality, but that current management of water resources was ineffective. Nearly all interviewees were aware of climate change and thought it to be anthropogenic. May reported experiencing higher temperatures, precipitation changes, and higher water scarcity and attributed those fluctuations to climate change. 65% of interviewees were at least somewhat familiar with hydrological models, though only 28% had ever used them or their output. Even with model usage results being low, 100% of respondents believed hydrological models to be very useful water management tools. Understanding how water, climate change, and hydrological models are perceived by this population of people is essential to improving their water management practices in the face of climate change.

The relationship between pain intensity and severity and depression in older people: exploratory study

BACKGROUND: Pain and depression are known to be associated in later life, and both have a negative effect on physical performance both separately and in combination. The nature of the relationships between pain intensity and depression in elderly persons experiencing pain is less clear. The objectives of this study were to explore which factors are associated with depressed mood in older people experiencing pain, and to test the hypothesis that older people experiencing pain are at risk of depressed mood according to the severity or frequency of their pain. In addition we explored whether other potentially modifiable factors might increase the risk of depressed mood in these persons. METHODS: The study is a secondary analysis of baseline data for four hundred and six community-dwelling non-disabled people aged 65 and over registered with three group practices in suburban London who had experienced pain in the past 4 weeks. Intensity and frequency of pain was measured using 24 item Geriatric Pain Measure (GPM) and the presence of depressive symptoms using the 5 item Mental Health Inventory. Risk for social isolation was measured using the 6 item Lubben Social Network scale and instrumental activities of daily living (IADL) were also measured. RESULTS: Overall 76 (19%) had depressed mood. Pain frequency and severity were not statistically significantly associated with depressed mood in this population. In multivariate analyses, significant predictors of the presence of depressive symptoms were difficulties with basic ADLs (OR 2.8, 95% CI 1.1.7.8), risk for social isolation (OR 4.1, 95% CI 1.8-9.3), and basic education only (OR 2.2, 95% CI 1.1-4.4). CONCLUSION: Older people experiencing pain are also likely to experience depression. Among those experiencing pain, social network and functional status seem to be more important predictors of depressive symptoms than the severity of pain. Further studies should evaluate whether improvement of social network and functional status might reduce depressive symptoms in older patients.

Impacts of changing climate and land use on vegetation dynamics in a Mediterranean ecosystem: insights from paleoecology and dynamic modeling

Forests near the Mediterranean coast have been shaped by millennia of human disturbance. Consequently, ecological studies relying on modern observations or historical records may have difficulty assessing natural vegetation dynamics under current and future climate. We combined a sedimentary pollen record from Lago di Massacciucoli, Tuscany, Italy with simulations from the LandClim dynamic vegetation model to determine what vegetation preceded intense human disturbance, how past changes in vegetation relate to fire and browsing, and the potential of an extinct vegetation type under present climate. We simulated vegetation dynamics near Lago di Massaciucoli for the last 7,000 years using a local chironomid-inferred temperature reconstruction with combinations of three fire regimes (small infrequent, large infrequent, small frequent) and three browsing intensities (no browsing, light browsing, and moderate browsing), and compared model output to pollen data. Simulations with low disturbance support pollen-inferred evidence for a mixed forest dominated by Quercus ilex (a Mediterranean species) and Abies alba (a montane species). Whereas pollen data record the collapse of A. alba after 6000 cal yr bp, simulated populations expanded with declining summer temperatures during the late Holocene. Simulations with increased fire and browsing are consistent with evidence for expansion by deciduous species after A. alba collapsed. According to our combined paleo-environmental and modeling evidence, mixed Q. ilex and A. alba forests remain possible with current climate and limited disturbance, and provide a viable management objective for ecosystems near the Mediterranean coast and in regions that are expected to experience a mediterranean-type climate in the future.
