A gestão das Instituições de Ensino Superior está a ser repensada num contexto de globalização tendo em conta a missão destas, a responsabilidade e a sua cultura (ou culturas), impondo-se novos modelos de gestão e governação. A Qualidade e a Responsabilidade Social do Ensino Superior constituem um tema pertinente e actual. As transformações estruturais que as sociedades atravessam aconselham e justificam da parte do Ensino Superior uma atitude consentânea com as necessidades daquelas. Os desafios que, as Instituições de Ensino Superior enfrentam, exigem novas perspectivas estratégicas e nova visão perante cenários de incerteza que surgem a nível mundial, desempenhando a liderança um papel fundamental na qualidade destas instituições. Neste sentido, lança-se no presente estudo, a seguinte questão: Que Modelos de Gestão e Governação contribuem para a melhoria da Qualidade no Ensino Superior? A metodologia utilizada para a realização deste estudo passa pelo delineamento de uma estratégia com cinco fases: elaboração de um plano ajustável à evolução do trabalho, levantamento do estado da arte de uma forma gradual, trabalho de pesquisa e criação, escrita da tese e análise crítica e reflexão. Para além de outros aspectos relevantes no domínio do Ensino Superior, foram estudados diversos modelos, Modelos de Excelência, modelos para implementação de Sistemas de Gestão da Qualidade, Gestão Ambiental, Gestão da Segurança e Saúde do Trabalho, Gestão de Risco; entre outros. Criaram-se diversos Indicadores de Responsabilidade Social neste contexto e foi feito um estudo piloto no âmbito da Responsabilidade Social em Instituições de Ensino Superior. Por último, destacaram-se as conclusões que decorrem do estudo piloto efectuado, bem como reflexões que surgem da investigação teórica realizada. O estudo piloto efectuado permitiu concluir, por exemplo, que existem indícios de algum alheamento no seio das Instituições às temáticas relacionadas com os princípios éticos e com a educação ambiental. Por outro lado, uma grande parte dos indivíduos inquiridos disseram não ter qualquer opinião quando confrontados com questões sobre Participação Social Responsável, Investigação Socialmente Útil e Gestão Social do Conhecimento. Conclui-se que as questões para as pessoas ainda são muito vagas, daí que, faça sentido o debate de todas estas questões, bem como estudos que contribuam para uma mudança de paradigma relativamente à educação, e em particular no Ensino Superior, com vista à qualidade, num sentido abrangente.

The management of Higher Education Institutions is being rethought, with the mission and culture of the institutions changing due to globalization, resulting in new models of management and governance. The quality of Higher Education and its obligations to society are of current importance. The structural changes that the society has gone through requires a response in higher education that matches the changing needs of the society. Higher Education Institutions require new perspectives and a new strategic vision to cope with the uncertainty arising at a global scale, and this plays a role in their quality and whether they are leading institutions. Thus the following question arises: Which forms of management and governance contribute to the improvement of quality in higher education? The methodology for this study was designed with five stages: preparation of a plan of work within the thesis, the gradual progression to understanding the up-to-date understanding of Higher Education Research, generating research hypotheses and creating further understanding, writing the thesis with critical analysis and reflection. In addition to other relevant issues in higher education, different models were studied: Models of excellence, Models for implementation of Quality Management Systems, Environmental Management, Occupational Health and Safety Management, Risk Management, among others. Several indicators of Social Responsibility were created in this context and a pilot study was conducted in the area of Social Responsibility in Higher Education Institutions. Finally the conclusions resulting from the pilot study are presented and questions arising from the theoretical research are discussed. For example, the pilot study showed that there are indicators of a lack of understanding within the institutions to issues related to ethical and environmental education. Moreover, a large proportion of respondents said individuals have no opinion when confronted with questions on Responsible Social Involvement and Social Research and Social Management of Useful Knowledge. It is concluded that people have a vague awareness of these issues, so these concepts are new to them.

BACKGROUND: Psychological stress negatively influences food intake and food choices, thereby contributing to the development of childhood obesity. Physical activity can also moderate eating behavior and influence calorie intake. However, it is unknown if acute physical activity influences food intake and overall energy balance after acute stress exposure in children. We therefore investigated the impact of acute physical activity on overall energy balance (food intake minus energy expenditure), food intake, and choice in the setting of acute social stress in normal weight (NW) and overweight/obese (OW/OB) children as well as the impact of psychological risk factors. METHOD: After receiving written consent from their parents, 26 NW (BMI < 90(th) percentile) and 24 7-to 11-year-old OW (n = 5)/OB (n = 19, BMI ≥ 90(th) percentile) children were randomly allocated using computer-generated numbers (1:1, after stratification for weight status) to acute moderate physical or to sedentary activity for 30 min. Afterwards, all children were exposed to an acute social stressor. Children and their parents completed self-report questionnaires. At the end of the stressor, children were allowed to eat freely from a range of 12 different foods (6 sweet/6 salty; each of low/high caloric density). Energy balance, food intake/choice and obesity-related psychological risk factors were assessed. RESULTS: Lower overall energy balance (p = 0.019) and a decreased choice of low density salty foods (p < 0.001) in NW children compared with OW/OB children was found after acute moderate physical activity but not sedentary activity. Independent of their allocation, OW/OB children ate more high density salty foods (104 kcal (34 to 173), p = 0.004) following stress. They scored higher on impulsive behavior (p = 0.005), restrained eating (p < 0.001) and parental corporal punishment (p = 0.03), but these psychological factors were not related to stress-induced food intake/choice. Positive parenting tended to be related to lower intake of sweet high density food (-132 kcal, -277 to 2, p = 0.054). CONCLUSIONS: In the setting of stress, acute moderate physical activity can address energy balance in children, a benefit which is especially pronounced in the OW/OB. Positive parenting may act as a protective factor preventing stress-induced eating of comfort food. TRIAL REGISTRATION: clinicaltrials.gov NCT01693926 The study was a pilot study of a project funded by the Swiss National Science Foundation (CRSII3_147673).

Study objectives: Many major drugs are not available in paediatric form. The aim of this study was to develop a stable liquid solution of captopril for oral paediatric use allowing individualised dosage and easy administration to newborn and young patients. Methods: A specific HPLC-UV method was developed. In a pilot study, a number of formulations described in the literature as affording one-month stability were examined. In the proper long-term study, the formulation that gave the best results was then prepared in large batches and its stability monitored for two years at 5°C and room temperature, and for one year at 40°C. Results: Most formulations described in the literature were found wanting in our pilot study. A simple solution of the drug (1 mg/mL) in purified water (European Pharmacopeia) containing 0.1% disodium edetate (EDTA-Na) as preservative proved chemically and microbiologically stable at 5°C and room temperature for two years. Conclusion: The proposed in-house formulation fulfils stringent criteria of purity and stability and is fully acceptable for oral administration to newborn and young patients.

La publicación de artículos científicos que tratan los trastornos del comportamiento alimentario (TCA) se ha incrementado en los últimos años y han experimentado un aumento significativo que puede ser atribuido a diferentes factores, entre ellos el surgimiento de nuevas publicaciones más selectivas y especializadas. La creciente investigación examina las preocupaciones de la imagen corporal y otras conductas asociadas, además de realizar investigaciones con diversos grupos poblacionales que incluyen a hispanos, asiáticos, europeos, etc. Este trabajo, muestra una revisión realizada a 136 artículos publicados en 67 revistas de ámbito internacional. Los artículos comprenden una selección realizada entre el año 2004 y el año 2008, como fruto de una revisión bibliográfica que sirvió de base para el desarro-llo del proyecto I+D denominado “La Publicidad de TV entre otros factores socioculturales influyentes en los TCA, estudio experimental y panel de expertos internacional” (2006-2010), proyecto del cual las autoras forman parte. En el artículo se concluye que existe una amplia tendencia a examinar los medios de comunicación y su influencia en los TCA y que las muestras tienden a utilizar a mujeres en su mayoría jóvenes, las cuales presentan un mayor grado de incidencia hacia los trastornos alimentarios que los hombres jóvenes. Se observó además que los investigadores detectan la sintomatología en grupos con una edad cada vez menor.

Introduction: Schizophrenia is associated with multiple neuropsychological dysfunctions, such as disturbances of attention, memory, perceptual functioning, concept formation and executive processes. These cognitive functions are reported to depend on the integrity of the prefrontal and thalamo-prefrontal circuits. Multiple lines of evidence suggest that schizophrenia is related to abnormalities in neural circuitry and impaired structural connectivity. Here, we report a preliminary case-control study that showed a correlation between thalamo-frontal connections and several cognitive functions known to be impaired in schizophrenia. Materials and Methods: We investigated 9 schizophrenic patients (DSM IV criteria, Diagnostic Interview for Genetic Studies) and 9 age and sex matched control subjects. We obtained from each volunteer a DT-MRI dataset (3 T, _ _ 1,000 s/mm2), and a high resolution anatomic T1. The thalamo- frontal tracts are simulated with DTI tractography on these dataset, a method allowing inference of the main neural fiber tracks from Diffusion MRI data. In order to see an eventual correlation with the thalamo-frontal connections, every subject performs a battery of neuropsychological tests including computerized tests of attention (sustained attention, selective attention and reaction time), working memory tests (Plane test and the working memory sub-tests of the Wechsler Adult Intelligence Scale), a executive functioning task (Tower of Hanoï) and a test of visual binding abilities. Results: In a pilot case-control study (patients: n _ 9; controls: n _ 9), we showed that this methodology is appropriate and giving results in the excepted range. Considering the relation of the connectivity density and the neuropsychological data, a correlation between the number of thalamo- frontal fibers and the performance in the Tower of Hanoï was observed in the patients (Pearson correlation, r _ 0.76, p _ 0.05) but not in control subjects. In the most difficult item of the test, the least number of fibers corresponds to the worst performance of the test (fig. 2, number of supplementary movements of the elements necessary to realize the right configuration). It's interesting to note here that in an independent study, we showed that schizophrenia patients (n _ 32) perform in the most difficult item of the Tower of Hanoï (Mann-Whitney, p _ 0.005) significantly worse than control subjects (n _ 29). This has been observed in several others neuropsychological studies. Discussion: This pilot study of schizophrenia patients shows a correlation between the number of thalam-frontal fibers and the performance in the Tower of Hanoï, which is a planning and goal oriented actions task known to be associated with frontal dysfonction. This observation is consistent with the proposed impaired connectivity in schizophrenia. We aim to pursue the study with a larger sample in order to determine if other neuropsychological tests may be associated with the connectivity density.

One of the aims of the MEDEX project is to improve the knowledge of high-impact weather events in the Mediterranean. According to the guidelines of this project, a pilot study was carried out in two regions of Spain (the Balearic Islands and Catalonia) by the Social Impact Research group of MEDEX. The main goal is to suggest some general and suitable criteria about how to analyse requests received in Meteorological Services arising out of the damage caused by weather events. Thus, all the requests received between 2000 and 2002 at the Servei Meteorològic de Catalunya as well as at the Division of AEMET in the Balearic Islands were analysed. Firstly, the proposed criteria in order to build the database are defined and discussed. Secondly, the temporal distribution of the requests for damage claims is analysed. On average, almost half of them were received during the first month after the event happened. During the first six months, the percentage increases by 90%. Thirdly, various factors are taken into account to determine the impact of specific events on society. It is remarkable that the greatest number of requests is for those episodes with simultaneous heavy rain and strong wind, and finally, those that are linked to high population density.

The aim of this pilot study is to analyse the discourse of fathers of toddlers concerning fatherhood and the link between some particularities in the discourse and family alliance. The sample consists of 13 Swiss first time fathers (5 fathers of girls and 8 of boys). In order to evaluate the paternal discourse, the fathers were given a semi-structured interview, which was later analysed using the research package Alceste. The family alliance, i.e., the degree of coordination among the partners when executing a task together, was assessed through the Lausanne Trilogue Play (Fivaz-Depeursinge & Corboz-Warnery, 1999). The main results indicated an interesting link between classes of paternal discourse grouped around the following themes "affective relationship", "daily routine" and "educational goals", and the family alliance (defined in two major categories; functional and problematic alliances). Finally, clinical perspectives on links between paternal representations and family functioning at an interactive level are discussed

PURPOSE: Anhedonia is a challenging symptom of schizophrenia and remains largely recalcitrant to current pharmacological treatments. The goal of this exploratory pilot study was to assess if a cognitive-sensory intervention could improve anticipatory pleasure. DESIGN AND METHODS: Five participants meeting the Diagnostic and Statistical Manual of Mental Disorders (4th edition, Text Revision) criteria for schizophrenia, presenting severe anhedonia and stabilized on atypical antipsychotic medication, received between 10 hours and 25 hours of training. FINDINGS: Results show that the patients improved on the anticipatory scale of the Temporal Experience of Pleasure Scale. Daily activities of the patients were also increased. PRACTICE IMPLICATIONS: These preliminary data need to be interpreted with caution given the small sample of the study, but they offer promising paths to develop new interventions to alleviate anhedonia in schizophrenia.

Background and objective: Optimal care of diabetic patients (DPs) decreases the risk of complications. Close blood glucose monitoring can improve patient outcomes and shorten hospital stay. The objective of this pilot study was to evaluate the treatment of hospitalized DPs according to the current standards, including their diabetic treatment and drugs to prevent diabetes related complications [=guardian drugs: angiotensin converting enzyme inhibitors (ACEI) or Angiotensin II Receptor Blockers (ARB), antiplatelet drugs, statins]. Guidelines of the American Diabetes Association (ADA) [1] were used as reference as they were the most recent and exhaustive for hospital care. Design: Observational pilot study: analysis of the medical records of all DPs seen by the clinical pharmacists during medical rounds in different hospital units. An assessment was made by assigning points for fulfilling the different criteria according to ADA and then by dividing the total by the maximum achievable points (scale 0-1; 1 = all criteria fulfilled). Setting: Different Internal Medicine and Geriatric Units of the (multi-site) Ho^pital du Valais. Main outcome measures: - Completeness of diabetes-related information: type of diabetes, medical history, weight, albuminuria status, renal function, blood pressure, (recent) lipid profile. - Management of blood glucose: Hb1Ac, glycemic control, plan for treating hyper-/hypoglycaemia. - Presence of guardian drugs if indicated. Results: Medical records of 42 patients in 10 different units were analysed (18 women, 24 men, mean age 75.4 ± 11 years). 41 had type 2 diabetes. - Completeness of diabetes-related information: 0.8 ± 0.1. Information often missing: insulin-dependence (43%) and lipid profile (86%). - Management of blood glucose: 0.5 ± 0.2. 15 patients had suboptimal glycemic balance (target glycaemia 7.2-11.2 mmol/ l, with values[11.2 or\3.8 mmol/l, or Hb1Ac[7%), 10 patients had a deregulated balance (more than 10 values[11.2 mmol/l or \3.8 mmol/l and even values[15 mmol/l). - Presence of guardian drugs if indicated: ACEI/ARB: 19 of 23 patients (82.6%), statin: 16 of 40 patients (40%), antiplatelet drug: 16 of 39 patients (41%). Conclusions: Blood glucose control was insufficient in many DPs and prescription of statins and antiplatelet drugs was often missing. If confirmed by a larger study, these two points need to be optimised. As it is not always possible and appropriate to make those changes during hospital stay, a further project should assess and optimise diabetes care across both inpatient and outpatient settings.

PURPOSE: To use diffusion-tensor (DT) magnetic resonance (MR) imaging in patients with essential tremor who were treated with transcranial MR imaging-guided focused ultrasound lesion inducement to identify the structural connectivity of the ventralis intermedius nucleus of the thalamus and determine how DT imaging changes correlated with tremor changes after lesion inducement. MATERIALS AND METHODS: With institutional review board approval, and with prospective informed consent, 15 patients with medication-refractory essential tremor were enrolled in a HIPAA-compliant pilot study and were treated with transcranial MR imaging-guided focused ultrasound surgery targeting the ventralis intermedius nucleus of the thalamus contralateral to their dominant hand. Fourteen patients were ultimately included. DT MR imaging studies at 3.0 T were performed preoperatively and 24 hours, 1 week, 1 month, and 3 months after the procedure. Fractional anisotropy (FA) maps were calculated from the DT imaging data sets for all time points in all patients. Voxels where FA consistently decreased over time were identified, and FA change in these voxels was correlated with clinical changes in tremor over the same period by using Pearson correlation. RESULTS: Ipsilateral brain structures that showed prespecified negative correlation values of FA over time of -0.5 or less included the pre- and postcentral subcortical white matter in the hand knob area; the region of the corticospinal tract in the centrum semiovale, in the posterior limb of the internal capsule, and in the cerebral peduncle; the thalamus; the region of the red nucleus; the location of the central tegmental tract; and the region of the inferior olive. The contralateral middle cerebellar peduncle and bilateral portions of the superior vermis also showed persistent decrease in FA over time. There was strong correlation between decrease in FA and clinical improvement in hand tremor 3 months after lesion inducement (P < .001). CONCLUSION: DT MR imaging after MR imaging-guided focused ultrasound thalamotomy depicts changes in specific brain structures. The magnitude of the DT imaging changes after thalamic lesion inducement correlates with the degree of clinical improvement in essential tremor.

OBJECTIVES: Lesion detection and characterization in multiple sclerosis (MS) are an essential part of its clinical diagnosis and an important research field. In this pilot study, we applied the recently introduced two inversion-contrast magnetization-prepared rapid gradient echo sequence (MP2RAGE) to patients with early-stage MS.¦MATERIALS AND METHODS: The MP2RAGE is a 3-dimensional (3D) magnetization-prepared rapid gradient echo derivative providing homogeneous T1 weighting and simultaneous T1 mapping. The MP2RAGE performance was compared with that of 2 clinical routine sequences (2D fluid-attenuated inversion recovery [FLAIR] and 3D magnetization-prepared rapid gradient echo [MP-RAGE]) and 2 state-of-the art clinical research sequences (the 3D FLAIR-SPACE [sampling perfection with application-optimized contrasts by using different flip-angle evolutions], a fluid-attenuated variable flip-angle fast spin echo technique, and the 3D double-inversion recovery SPACE). A cohort of 10 early-stage female MS patients (age, 31.6 ± 4.7 years; disease duration, 3.8 ± 1.9 years; median expanded disability status scale score, 1.75) and 10 age- and gender-matched controls were enrolled after approval of the local institutional review board was obtained. Multiple sclerosis lesions were identified and assigned to brain locations and tissue types by two experienced physicians in all 5 contrasts. Subsequently, lesions were manually delineated for comparison and statistical analysis of lesion count, volume and quantitative measures.¦RESULTS AND CONCLUSIONS: The results show that the 3D T1-weighted high-resolution MP2RAGE contrast provides a sensitive means for MS lesion assessment. The additional quantitative T1 relaxation time maps obtained with the MP2RAGE provide further potential diagnostic and prognostic information that could help (a) to better discriminate lesion subtypes and (b) to stage and predict the activity and the evolution of MS. Results also indicate that the T2-weighted double-inversion recovery and FLAIR-SPACE contrasts are attractive complements to the MP2RAGE for lesion detection.
