We presented here an overview about Hip Hop, its main characteristics and elements. Then, we focused on the concepts of lived time and care, as well as their characteristics, after that, we conclude with some considerations about possible connections between these concepts allied to Hip Hop. The movement participants are described as active in the learning life, abandoning the figure of mere receptors of an unequal social model. That is, in the Hip Hop, they bring off their lives by means of an ethical education. Through the categories analysis on apprehended discourses, it is concluded that the Hip Hop gives to the participants acquisition opportunities of a life motivation, by the time experience in relation to the place and the others. Thus, it permits that, in the dialog between individual and its context, the foundation of a successful human being life. Furthermore, the Hip Hop movement visibility can contribute to the comprehension of the current society, recognizing in this movement capable subjects to formulate consistent suggestions of change, in an unequal social model context. / Tendo como ponto de partida a Fenomenologia aplicada a um contexto social específico, o movimento Hip Hop, este trabalho discorre sobre o cotidiano de jovens pertecentes ao movimento, com o objetivo de apreender os significados do viver o tempo. Apresentamos aqui um panorama sobre o Hip Hop, com suas principais características e os elementos que o compõe. Em seguida, abordamos os conceitos sobre o tempo vivido e o cuidar, bem como suas características, logo após, finalizamos com algumas considerações acerca das possíveis ligações destes conceitos com o Hip Hop. Participantes desse movimento são descritos ativos na aprendizagem da vida, deixando de serem meros receptores de um modelo social desigual. Ou seja, no Hip Hop eles resgatam suas vidas por meio de uma formação ética. Mediante o exame das categorias diante dos discursos apreendidos, é concluso que o Hip Hop confere aos seus participantes oportunidades de aquisição de um sentido para a vida, por intermédio da experiência do tempo em articulação com o espaço e com a relação com os outros. Com isso, permite-se que no diálogo do indivíduo com seu contexto sejam construídos, em indissociável inter-relação, os fundamentos de uma vida humana bem sucedida. Portanto, a visibilidade do movimento Hip Hop pode contribuir para uma compreensão da sociedade atual, reconhecendo neste movimento sujeitos competentes para formular propostas de mudanças abrangentes e consistentes, dentro de um modelo social desigual.

A tese pretende analisar as relações entre Literatura moderna, Geografia e Sociedade no processo de modernização social, através do estudo de seis escritores: Charles Baudelaire, Machado de Assis, Joseph Conrad, Franz Kafka, Carlos Drummond de Andrade e João Antônio. O percurso busca mostrar como a modernização social, produzindo formas de espaço social abstrato (Lefebvre) adequadas ao processo de acumulação capitalista, é literariamente mimetizada e reconstruída por tais escritores. O processo de modernização aparece, então, como domínio do trabalho abstrato e, em suas crises, como um estado de exceção, figurado pela literatura em três níveis espaciais fundamentais interligados, mas não-idênticos: ao nível do concebido (pela política e as ideologias), do praticado/percebido (na vida cotidiana) e do vivido (nas singularidades subjetivas, nos limites do real inconsciente). Assim, teríamos a Literatura como um meio de mapeamento cognitivo de processos sócio-espaciais modernos. / The thesis intends to analyse the relationships between Modern Literature, Geography, and Society within the process of social modernization, through the study of six writers: Charles Baudelaire, Machado de Assis, Joseph Conrad, Franz Kafka, Carlos Drummond de Andrade and João Antônio. This itinerary aims to show how social modernization, producing forms of abstract social space (Lefebvre) related to the capitalist process of accumulation, is literarily mimetized and reconstructed by these writers. The modernization process appears then as imposition of abstract labor and, in its crisis, as a state of exception, thematized by literature in three interconnected but non-identical spatial levels: at the level of the conceived (by politics and ideologies), of the perceived (praxis in everyday life), and of lived experiences (in subjective singularities, in the limits of the unconscious). Thus, Literature appears as cognitive mapping of modern social and spatial processes.

Correctional officers work in a coercive environment and as such they are confronted with various challenges on a daily basis. Research found that the unique stressors that correctional officers experience result in stress which can negatively impact their physical and psychological health as well as their family life. However, limited research has been conducted to identify the stressors that are relevant to the South African correctional officer. Therefore, the aim of this study was to investigate South African correctional officers’ lived experiences of their work and work environment and the Employee Assistance Programme and the meaning they attached to them. Purposive and snowball sampling techniques were utilised to select the 20 participants from the two correctional centres of the Department of Correctional Services in Worcester, Western Cape. The sample consisted of 11 male and 9 female correctional officers between the ages of 26 and 56 years with a mean age of 43.4. A qualitative approach was utilised to obtain in-depth insights into the lived experiences and attributed meanings of participants. Individual interviews were conducted with the participants by utilising a semi-structured interview guide. A demographic questionnaire was completed by each participant after the interview. The interviews were audio-recorded with the written permission of each participant and transcribed for analysis. Through the use of Interpretive Phenomenological Analysis (IPA) 7 themes were identified namely: (a) confronting various challenges on a daily basis (b) various dimensions of correctional officers life affected (c) neglect of correctional officers’ well-being (d) coping mechanisms (e) barriers preventing corrections officers from utilising the EAP (f) a recognition of the positive value of the EAP (g) personal meaning derived from work. In addition, the themes consist of various subthemes. The findings of the study suggest that correctional officers are confronted with various challenges on a daily basis, which include lack of input into decision making, lack of support from management, lack of trust in management, pressure caused by staff shortages, lack of resources, inadequate training opportunities and a lack of promotion system. Furthermore, participants revealed that their work and work environment had a negative impact on their physical and psychological health as well as their family life. In addition, participants reported that aspects of their well-being are neglected which include a lack of interest from management in their problems, a lack of recognition and motivation from management as well as a lack of team-building opportunities. Various coping mechanisms were utilised by the participants which seems to act as a buffer against the negative effects of their stressful work and work environment. These coping mechanisms include conflict resolution and communication skills, religion, sport, positive thinking, resilience as well as family and co-worker support. A variety of barriers that prevent participants from using the EAP service that are offered at work were identified. These barriers indicated by the participants included a lack of trust in the EAP, the stigma attached to using the EAP, difficulty relating with the EAP practitioner, a negative perception of the EAP, and insufficient marketing of the EAP. Despite the barriers, participants recognised the overall positive value of the EAP service in the Department of Correctional Service. Participants appear to find meaning in their work. Some participants expressed the satisfaction that they experienced from their job while others expressed the sense of reward that they experience from their job. Recommendations for further research include the evaluation of the EAP programme to determine its effectiveness on a national level, more involvement from management in ground floor correctional officers, providing additional teambuilding oppertunities and reintroducing Wellness Days. A limitation of the study is that only a small sample of correctional officers limited to two correctional facilities in Worcester, Western Cape, was used. Therefore, the findings of the study could not be generalised to the whole population of South African correctional officers. / Psychology

Intimate partner violence [IPV] is a preventable and costly societal issue that has reached epidemic proportions. Women are often the victims of IPV, and millions of children are exposed to it annually. The purpose of this study was to explore experiences of Puerto Rican mothers and their perceptions of how IPV exposure may have impacted their children using resilience theory. Data were collected via audiotaped individual interviews with 9 Puerto Rican mothers who endured an array of escalating IPV, often exacerbated by the perpetrators use of alcohol or drugs, and had IPV-exposed children aged 6 -11 years. Data analysis integrated content and thematic procedures. Interview data was transcribed, read, audited and coded based on compelling statements, quotes, and sentences made by the participants. The coded clusters were further evaluated, reduced to significant statements, then grouped into themes that captured the essence of the participants lived experiences and of the group. The mothers separated because they feared for their lives and the effect of IPV on the children. Once separated the mothers felt isolated, lived in shelters which were unconducive to childrearing, and had challenges navigating the system. They perceived their IPV-exposed children exhibited a multitude of behaviors including PTSD but that most were showing signs of resilience. Their IPV was perpetrated by males who were mostly the biological fathers of their children who used controlling behaviors towards the kids. The potential positive social change impact of this study is to empower Puerto Rican mothers to disclose IPV and to better inform health care providers regarding the impact of IPV on children aged 6 -11 years in an effort to increase the health, well-being, and resiliency of this vulnerable population.

In the African American community, the Black Church and its clergy have served as gatekeepers to formal mental health treatment. Little is known about the beliefs of African American Christian senior pastors about mental health treatment and their personal views influencing their counsel to congregants seeking support through the church. This transcendental phenomenological study explored the lived experiences of African American Christian senior pastors in relation to how they understand mental health treatment and provide it to their congregants. The research questions explored three areas: (a) the senior pastors' experiences in rendering mental health treatment, (b) the senior pastors' personal experiences with mental health treatment, and (c) the senior pastors' views on their effectiveness in rendering mental health treatment to congregants. An emergent hand coding analysis of participant narratives collected from 6 participant semi-structured interviews generated 3 main themes and 14 sub-themes related to participant experiences. The results showed the senior pastors not wanting to do harm when congregants sought mental health support through the church; hence, the pastors referred congregants to formal treatment when issues were beyond their scope. Also most of the senior pastors felt comfortable participating in formal mental treatment as needed because it was beneficial for addressing personal and professional challenges. This study can assist the mental health community in making positive social change via the development of relationships and/or partnerships with African American Christian senior pastors looking to refer congregants to formal mental health treatment.

<p>Syftet med studien var att beskriva hur nyutexaminerade sjuksköterskor upplevde sin första tid i yrket utifrån känslor, tankar, stöd och bemötande. Studien genomfördes som en kvalitativ intervjustudie med fyra informanter som arbetat på Gävle sjukhus mellan 6-18 månader. Resultatet redovisades utifrån studiens frågeställningar och visade att nyutexaminerade sjuksköterskor upplevde många olika känslor och tankar inför sin nya yrkesroll. Känslor såsom rädsla, nervositet och förväntan var några exempel. Stödet och bemötandet från andra sjuksköterskor och närmaste chef var övervägande bra, medan bemötandet från under-sköterskor och läkare upplevdes som mindre bra. Faktorer som ödmjukhet, trygghet och erfarenhet var något som sjuksköterskorna utvecklade med tiden och det underlättades av att de gavs utrymme för att vara nya och osäkra. En bra introduktion på arbetsplatsen var också underlättande. Slutsatsen som dras är att merparten av nyutexaminerade sjuksköterskor går igenom en liknande känslomässig process under den första tiden i yrket. Det som kan påverka den processen positivt eller negativt är de yttre faktorerna; utbildning, introduktion samt teamwork och det är dessa som det behövs bättre planering kring.</p> / <p>The aim of the study was to describe how newly graduated nurses experienced their first period of time in the profession on the basis of emotions, thoughts, support and treatment. The study was conducted as a qualitative interview study with four participants who had worked at Gävle Hospital between 6-18 months. The results were reported from the question formulations in the study and showed that newly graduated nurses experienced many different emotions and thoughts with their new professional role. Feelings such as fear, nervousness and anticipation were a few examples. The support and the interaction between other nurses and the manager of the ward were considered good, while the interaction with the assistant nurses and doctors worked less well. Factors such as humility, experience and gaining security in their new profession was something that the nurses developed over time and it was facilitated by the fact that they were given the space to be new and insecure. A good introduction to the ward was also facilitation.<strong> </strong>The conclusion reached is that the majority of newly graduated nurses goes through a similar emotional process in their first period of time in the profession. What can affect the process positively or negatively is the external factors; education, introduction and teamwork, and it is those factors that needs better planning.</p>

<p>The use of positron-emitting tracers has been extended beyond tomographic facilities in the last few years, giving rise to a general positron-emitting tracing technique. The methodological part of the present thesis involved the evaluation of the performance of storage phosphor (SP) plates, with tracers labeled with high-energy, short-lived, positron-emitting radionuclides, using homogenized tissue specimens and autoradiography with frozen brain sections. The SP plates showed superior sensitivity and a linear response over a wide radioactivity range. Autoradioradiography provided reliable results due to (a) adequate sensitivity for low radioactivity concentration, b) an excellent linear range, and (c) satisfactory resolution. Though equilibration time of receptor-ligand interaction was dependent upon section thickness, quantification was possib with thinner sections.</p><p>An initial finding using frozen section autoradiography of rat brain and spinal cord showed preferential binding of [¹¹C]4-NMPB, a muscarinic acetylcholine (mACh) receptor antagonist, to the M4 subtype of mACh receptors. Further work to ascertain this specificity, by use of binding studies on cell membranes from CHO-K1 cells expressing individual subtypes of human mACh receptors, suggested lack of subtype selectivity. With respect to the possible cliinical use in glutamatergic neuropathology, [¹¹C]cyano-dizocilpine, as a potential PET tracer for the N-methyl-D-aspartate (NMDA) subtype of glutamate receptors, was studied. The <i>in vivo</i> visualization of specific binding could not be achieved, though <i>in vitro</i> binding demonstrated good specificity and preferential binding to the activated for of the NMDA receptors.</p><p>The use of the glucose analogue [¹⁸F]fluorodeoxyglucose (FDG) to study glucose utilization was evaluated in experimental traumatic brain injury (TBI). A trauma-induced increased uptake of FDG was seen, whereas the uptake of [1-¹⁴C]glucose remained unchanged. This discrepancy might be due to the increased postraumatic affinity of FDG for the endothelial glucose transporter proteins and/or to the hexokinase enzyme. [¹¹C]Cyano-dizocilpine, [¹¹C]4-NMPB, and [¹¹C]flumazenil were utilized in autoradiography to evaluate changes in NMDA, mACh, and GABA_A receptors, espectively, in experimental TBI. Observations showed a global decrease in the binding potential BP) of (i) [¹¹C]cyano-dizocilpine acutely and 12 hrs after TBI, and (ii) of [¹¹C]4-NMPB at 12 hrs after TBI, and (iii) a decrease in the BP of [¹¹C]flumazenil in the cortex and hippocampus ipsilateral to the site of injury. The demonstrated changes in receptor binding after TBI are indicative of a widely dissipated effect of TBI on the particular neurotransmitter receptor systems as compared with what would be expected from FDG studies after TBI, i.e., a local disturbed neurotransmission.</p>

The interaction of magma with continental crust at convergent margins is fundamental to understanding if and how continents grow. Isotopic and elemental data constrain the progressive stages of development of the magmatic underpinnings of the long-lived Aucanquilcha Volcanic Cluster (AVC), situated atop the thick continental crust of the central Andes in northern Chile. Whole rock data are used in conjunction with mineral compositions to infer processes that gave rise to eleven million years of intermediate, dominantly dacite, arc volcanism. A pulse of volcanic activity at the AVC between ~5 and 2 Ma is bracketed by more sluggish rates. We document chemical changes in the lavas that accompany this eruptive evolution. Trace element data suggest that crystal fractionation and magma mixing were the dominant mechanisms generating the diversity observed in the AVC whole rock data. Fractionation was dominant during early and waning stages of magmatism, and magma mixing was an important process during the high flux period. Peak thermal maturity of the AVC underpinnings coincided with the high magma flux and likely promoted open system processes during this time. Mineral compositions from zircon, amphibole, pyroxene, and Fe-Ti oxides confirm the importance of material recycling in the production of evolved AVC rocks. Various geothermometers were employed to calculate the pre-eruptive conditions of AVC magma using mineral compositions. Pressure estimates from amphibole and two-pyroxene barometry indicate crystallization depths of 1 ��� 5 kb and 4 ��� 6 kb, respectively. Temperature estimates from zircon, Fe-Ti oxides, amphiboles, and pyroxenes indicate temperatures ranging from ~700��C to 1100��C. Zircon temperatures are always the lowest (700��C - 950��C), and pyroxene temperatures are always the highest (1000��C - 1100��C), with Fe-Ti oxide and amphiboles temperatures falling in between. U-Pb ages from zircons and thermometry from individual samples evidence the thermal maturation and consolidation of the underpinnings below the AVC, presumably culminating in a large, crystal-rich mush zone where magmas were trapped and processed. It is in these middle to upper crustal zones where magmatic diversity is attenuated and giant, relatively homogeneous batholiths are formed. Isotopes of AVC lavas are similar to values observed from other central Andes volcanic centers. Lead isotopes are consistent with the AVC's location within a Pb isotope transition zone between the Antofalla and Arequipa basement terranes. Oxygen and Sr isotopic ratios are high and Nd isotopic ratios low with respect to a depleted mantle. Through time, ������Sr/������Sr values of AVC lavas progressively increase from lows of ~0.70507 to ~0.70579 (upper values of 0.70526 to 0.70680), and ��Nd values decrease from highs of -1.0 to -4.6 (lows of -1.6 to -7.3). Similarly, O isotopes (�������O) show a slight increase in base level through time from lows of 6.5��� to 7.0��� (highs of 6.75��� ��� 7.5���). Dy/Yb and Sm/Yb ratios also increased systematically from highs of 2.11 to 3.45, and 2.76 to 6.67, respectively. Despite the temporal isotopic variation, there is little isotopic variation with indices of fractionation, suggesting this signal is the consequence of deep magmatic processing, here attributed to an expanding zone of melting, assimilation, storage, and homogenization (MASH) of mantle-derived magma in the deep crust. Upward expansion brought the MASH zone into contact with rocks that were increasingly evolved with respect to Sr and Nd isotopes, explaining the isotopic shifts. Downward expansion of the MASH zone enhanced garnet stability during basalt fractionation, explaining the increased Dy/Yb and Sm/Yb ratios. Mass balance calculations involving Sr, Nd, and O isotope modeling are consistent with a crustal component making up 10 - 30% of AVC lavas, implying that although the history of central Andean magmatism is replete with large scale crustal recycling, the current phase is largely a crust formation event. / Graduation date: 2012

Aim:  To describe and develop understanding of  the patient’s first encounter with the involved persons at the scene of an accident and at the emergency department; with a special focus on describing the meaning of emergency care of patients in these caring contexts.  Method: The thesis uses a reflective lifeworld research (RLR) approach founded on phenomenological philosophy. The purpose with this approach is to describe the essential meaning and the variations of a phenomenon. Interviews with a lifeworld perspective were used for data collection and analyzed according to the RLR approach for searching for the essence of the phenomenon.  The four essences in the studies (I-IV) establish a general structure for the phenomenon. Findings:  Emergency care is characterized by an organisation, whose goal and resources are focused on life-saving, and that encounters a human being with needs of emergency care as well as existential support. The responsibility in emergency care means an intertwining of doing and being.  The one who is in charge takes responsibility for performing or “doing” medical actions, and by “being” close and present in the situation the patient can at the same time feel an existential support. The responsibility for the injured or ill body is handed over to a chain of persons with more and more specialized competence and resources. This hand-over entails a relief for all involved but fails in one link in the chain, namely to explicitly hand back  the responsibility to the patient.  When the patient’s condition allows the distance to be larger the responsibility pales and the existential support decreases. A gap between doing and being arises where the patient is left to regain control and independence. The intertwining of doing and being, which appears as soon as the one in charge is close and present to the patient, facilitates the hand-over to the patient who in a natural way is able to receive the responsibility with possibilities to be able to conclude the encounter. Conclusions: A new understanding of emergency care appears which entails more than just life support measures.  Emergency care includes different ways of communication in order to hand over the responsibility and complete the care chain back to the patient in a safe way. The results highlight the importance of empowering patients with a confirming, communicative contact throughout the whole caring process in order for them to retain their identity. There are also implications for educating students and personnel in inter-professional communication and work. In order to assist the intertwining between doing and being there are needs for the development of supportive structures for inter-professional reflection, which in turn would improve the interaction between patients and professionals in their encounter.
