Com esta dissertação pretende-se estudar o modelo de avaliação de desempenho existente na Polícia de Segurança Pública (PSP), a nível central e a nível do Comando Distrital da PSP de Braga, bem como a forma como ambos os modelos se articulam.Tendo em conta a revisão de literatura efetuada, constata-se que a avaliação de desempenho tem vindo a assumir um papel importante na Polícia, sendo útil para melhorar os serviços prestados,apoiar na tomada de decisões, responsabilizar os gestores e prestar contas à sociedade. A literatura refere ainda que a Polícia é um serviço difícil de avaliar devido à diversidade de atividades que esta desenvolve e à dificuldade em aferir a segurança dos cidadãos e a redução da criminalidade.Para se perceber o modelo de avaliação existente na PSP propõe-se fazer um estudo de caso,através de entrevistas, contando com a colaboração do Diretor Nacional Adjunto da Unidade Orgânica de Recursos Humanos, do 2º Comandante Distrital do Comando Distrital de Braga e do Diretor do Gabinete de Estudos e Planeamento da Direção Nacional da PSP.Neste estudo verifica-se que o modelo de avaliação de desempenho da PSP é um modelo centralizado uma vez que é a Direção Nacional (DN) da PSP que define os objetivos estratégicos, os objetivos operacionais, os indicadores e as metas para todo o seu universo. Os resultados desta avaliação são apresentados no Relatório de Atividades da PSP. A nível central também é utilizado o Sistema Integrado de Gestão e Avaliação de Desempenho na Administração Pública – Quadro de Avaliação e Responsabilidades (SIADAP – QUAR). Por outro lado, ao nível do Comando Distrital de Braga verifica-se que não existe um modelo de avaliação de desempenho. Estes recebem a informação sobre os objetivos operacionais, os indicadores e as metas a atingir estabelecidas pela DN, que tentam cumprir num determinado período e no final comunicam-lhes os resultados. A DN agrega todos os resultados a nível Nacional e faz a avaliação global do desempenho da PSP.O estudo mostra ainda que há uma forte predisposição para a implementação de um modelo de avaliação de desempenho baseado na metodologia Balanced Scorecard (BSC), por este ser considerado um modelo eficaz, com larga utilização a nível mundial e com bons resultados alcançados. Atualmente a DN já define o seu quadro estratégico baseado nas quatro perspetivas do BSC: perspetiva do cliente, perspetiva financeira, perspetiva dos processos internos e perspetiva da aprendizagem. Contudo, até ao momento não são apresentados os resultados desta avaliação de acordo com o modelo BSC. Conclui-se, por isso, que o modelo de avaliação existente na PSP é um modelo extremamente centralizado na DN, sendo reduzido o envolvimento dos Comandos Distritais neste processo.

Objective: To quantify the neuronal and glial cell pathology in the hippocampus and the parahippocampal gyrus (PHG) of 8 cases of progressive supranuclear palsy (PSP). Material: tau-immunolabeled sections of the temporal lobe of 8 diagnosed cases of PSP. Method: The densities of lesions were measured in the PHG, CA sectors of the hippocampus and the dentate gyrus (DG) and studied using spatial pattern analysis. Results: Neurofibrillary tangles (NFT) and abnormally enlarged neurons (EN) were most frequent in the PHG and in sector CA1 of the hippocampus, oligodendroglial inclusions (“coiled bodies”) (GI) in the PHG, subiculum, sectors CA1 and CA2, and neuritic plaques (NP) in sectors CA2 and CA4. The DG was the least affected region. Vacuolation and GI were observed in the alveus. No tufted astrocytes (TA) were observed. Pathological changes exhibited clustering, the lesions often exhibiting a regular distribution of the clusters parallel to the tissue boundary. There was a positive correlation between the degree of vacuolation in the alveus and the densities of NFT in CA1 and GI in CA1 and CA2. Conclusion: The pathology most significantly affected the output pathways of the hippocampus, lesions were topographically distributed, and hippocampal pathology may be one factor contributing to cognitive decline in PSP.

In eight cases of progressive supranuclear palsy (PSP), neurofibrillary tangles (NFT) were numerous in the substantia nigra (SN), red nucleus (RN), locus caeruleus (LC), pontine nuclei (PN), and inferior olivary nucleus (ION) and abnormally enlarged neurons (EN) in the ION, LC and PN. Loss of Purkinje cells was evident in the cerebellum. Tufted astrocytes (TA) were abundant in the striatum, SN and RN and glial inclusions ('coiled bodies') (GI) in the midbrain (SN, RN) and pons (LC). Neuritic plaques were frequent in one case. NFT, GI, and TA densities were uncorrelated in most areas. NFT and EN densities were positively correlated in the midbrain and surviving neurons and disease duration in several areas. These results suggest: 1) predominantly subcortical pathology in PSP with widespread NFT while TA and GI have a more localized distribution, 2) little correlation between neuronal and glial pathologies, and 3) shorter duration cases may be more likely to develop cortical pathology. © 2007 Springer-Verlag.

Progressive supranuclear palsy (PSP) is a rare, degenerative disorder of the brain believed to affect between 1.39 and 6.6 individuals per 100,000 of the population. The disorder is likely to be more common than suggested by these data due to difficulties in diagnosis and especially in distinguishing PSP from other conditions with similar symptoms such as multiple system atrophy (MSA), corticobasal degeneration (CBD), and Parkinson’s disease (PD). PSP was first described in 1964 by Steele, Richardson and Olszewski and originally called Steele-Richardson-Olszewski syndrome. The disorder is the second commonest syndrome in which the patient exhibits ‘parkinsonism’, viz., a range of problems involving movement most typically manifest in PD itself but also seen in PSP, MSA and CBD. Although primarily a brain disorder, patients with PSP exhibit a range of visual clinical signs and symptoms that may be useful in differential diagnosis. Hence, the present article describes the general clinical and pathological features of PSP, its specific visual signs and symptoms, discusses the usefulness of these signs in differential diagnosis, and considers the various treatment options.

Aims: To quantify white matterpathology in progressive supranuclear palsy (PSP). Material: Histological sections of white matter of 8 PSP and 8 control cases \Method: Densities and spatial patterns of vacuolation, glial cell nuclei, and glial inclusions (GI) were measured in 8cortical and subcortical fiber tracts. Results: No GI wereobserved in control fiber tracts. Densities of vacuoles and glial cell nuclei were greater in PSP than in controls. In PSP, density of vacuoles was greatest in the alveus, frontopontine fibers (FPF), and central tegmental tract (CTT), and densities of glial cell nuclei were greater in cortical than subcortical regions.The highest densities of GI were observed in the basal ganglia, FPF, cerebellum, andsuperior frontal gyrus (SFG). Vacuoles, glialcells and GI were distributed randomly, uniformly,in regularly distributed clusters, or in large clusters across fiber tracts. GI wermore frequently distributed in regular clusters than the vacuoles and glial cell nuclei.Vacuoles, glial cell nuclei, and GI were not spatially correlated. Conclusions: The data suggest significant degeneration of white matter in PSP, vacuolation being related to neuronal loss in adjacent gray matterregions,GI the result of abnormal tau released from damaged axons, and gliosis a responseto these changes. © 2013.

The effects of lead exposure may endure through one's lifetime and can negatively effect educational performance. While the link between the cause and effects of lead poisoning has been identified, the application of lead health education as the mechanism of disease prevention has not. The purpose of this study was to examine whether caregiver participation in a family-based educational intervention can result in decreased lead exposure in low socioeconomic children. ^ Participants (n = 50) were caregivers of children 12 to 36 months of age. They were randomly selected from an urban clinic and randomly assigned to either a treatment or control group. The experimental design of this study involved two clinic visits. Parents in the treatment group were given the educational intervention during the first clinic visit while those in the control group were given the intervention during the second clinic visit. The intervention was reinforced with a lead education brochure coupled with a video on childhood lead poisoning. One instrument was used to test parental knowledge of lead poisoning both pre- and post-intervention. Blood lead levels in pediatric participants were tested using two blood lead screens approximately three to four months apart determined by well-child check-up schedules. ^ Findings from the analysis of variance showed the interaction between the change in blood lead level between the children's first and second clinic visits and the treatment level. This demonstrated a significant interaction between the differences of first and second clinic visits blood lead levels and the presence or absence of the educational intervention. ^ The findings from an analysis of covariance support that caregivers in the treatment group have significantly higher scores on the second clinic visit scores on the CLKT than the caregivers in the control group. These data suggest that the educational treatment is effective in increasing the knowledge of caregivers about the dangers of lead poisoning and the strategies for lead poisoning prevention. ^ Conclusions indicate that the education of adult caregivers can affect blood lead levels of children, the educational treatment increased the knowledge of caregivers, caregivers were able to carry out procedures taught, and caregivers retained knowledge over time. ^

My paper discusses three different ways in which stray dogs have been intertwined with ideologies of economic and urban development in Romania. I categorize results from archival and ethnographic research under three major time periods: early socialism, late socialism, and post-socialism. During early socialism stray dogs were seen to be damaging the soviet economy by killing species that humans could also hunt, like rabbits. During late socialism, stray dogs appeared as the enemies of the communist city, and the department of urban sanitation was given orders to poison dogs with strychnine. Finally, the increasing number of stray dogs in Bucharest after the collapse of communism was seen as a direct result of former communist demolitions, and was also taken as a sign of the collapsing state. Through such examples my paper discusses how the state and particular population groups have seen dogs as parts of an unwanted and dangerous nature, rather than a species that needs to be protected. I argue that distinctions of nature and culture have served discourses of civilization and the view of Bucharest as a model socialist, and then European city. Throughout my paper I juxtapose the treatment of stray dogs with other, more “valued” urban natures like the protection of parks, the wide-spread hobby of pigeon breeding during socialist years, the most recent debate on saving the rural area of Rosia Montana from non-environmentally friendly methods of gold extraction, and the current trend of healthy eating and living.

Understanding how seafood will be influenced by coming environmental changes such as ocean acidification is a research priority. One major gap in knowledge relates to the fact that many experiments are not considering relevant end points related directly to production (e.g., size, survival) and product quality (e.g., sensory quality) that can have important repercussions for consumers and the seafood market. The aim of this experiment was to compare the survival and sensory quality of the adult northern shrimp (Pandalus borealis) exposed for 3 wk to a temperature at the extreme of its thermal tolerance (11°C) and 2 pH treatments: pH 8.0 (the current average pH at the sampling site) and pH 7.5 (which is out of the current natural variability and relevant to near-future ocean acidification). Results show that decreased pH increased mortality significantly, by 63%. Sensory quality was assessed through semiqualitative scoring by a panel of 30 local connoisseurs. They were asked to rate 4 shrimp (2 from each pH treatment) for 3 parameters: appearance, texture and taste. Decreased pH reduced the score significantly for appearance and taste, but not texture. As a consequence, shrimp maintained in pH8.0 had a 3.4 times increased probability to be scored as the best shrimp on the plate, whereas shrimp from the pH 7.5 treatment had a 2.6 times more chance to be scored as the least desirable shrimp on the plate. These results help to prove the concept that ocean acidification can modulate sensory quality of the northern shrimp P. borealis. More research is now needed to evaluate impacts on other seafood species, socioeconomic consequences, and potential options.

Introdução: São poucos os estudos que em Portugal se dedicaram a explorar constructos como o autocriticismo, autocompaixão, saúde mental e o comprometimento organizacional. São nossos objetivos analisar estas associações na Polícia de Segurança Pública, considerando igualmente a influência de variáveis sociodemográficas e profissionais, bem como realizar análises preditivas que permitam verificar quais são as variáveis preditores do comprometimento organizacional. Metodologia: A amostra é constituída por 188 polícias com idades compreendidas entre os 30 e 56 anos (M = 43,75, DP = 5,66). Os participantes preencheram um protocolo integrante do projeto Organizar Positivamente do Instituto Superior Miguel Torga, composto por um questionário sociodemográfico, a SELFCS (Escala da Autocompaixão), a FSCRS (Escala das Formas do Autocriticismo e Autotranquilização), o MHI-5 (Mental Health Inventory) e o QCO (Questionário do Comprometimento Organizacional). Resultados: Os polícias parecem regular a sua relação com a organização através do comprometimento calculativo. A autocompaixão associa-se positivamente ao comprometimento afetivo, sobressaindo a capacidade de mindfulness. O autocriticismo, na forma eu inadequado - menos corrosivo que a forma eu detestado -, revela uma relação positiva com o comprometimento calculativo, pelo que a permanência na organização pode ser emocionalmente negativa, originar ataques ao eu e diminuir a capacidade afetiva. Porém, a capacidade autotranquilizadora (forma eu tranquilizador do autocriticismo) parece capacitar os polícias para o desenvolvimento de maiores níveis de comprometimento organizacional e afetivo. A idade, a antiguidade e menos habilitações literárias parecem favorecer o comprometimento calculativo. Discussão: A autocompaixão pode contribuir para uma atitude positiva e afetuosa do polícia para com a organização. Assim, através de uma intervenção baseada na autocompaixão e no mindfulness, com impacto positivo no comportamento afetivo e normativo, não só se poderá preservar e promover a saúde e o bem-estar dos polícias, mas também fomentar o empenho organizacional, atenuando os efeitos negativos da profissão policial. Esta abordagem poderá contribuir para os objetivos organizacionais, através da supressão das emoções aversivas, da diminuição da intenção de turnover e abandono da organização. / Introduction: There are few studies in Portugal that have been dedicated to explore constructs such as self-criticism, self-compassion, mental health and organizational commitment. Our goals are to analyze these associations at the Public Safety Police, considering also the influence of sociodemographic and professionals variables, as well as to conduct predictive analyses, in order to verify which variables may predict organizational commitment. Methodology: The sample consisted of 188 police with ages between 30 and 56 years (M = 43.75, SD = 5.66). The participants filled in a protocol from the project Organizar Positivamente, from Instituto Superior Miguel Torga, composed by a sociodemographic questionnaire, the SELFCS (Self-Compassion Scale), the FSCRS (Scale of Forms of Self-Criticism and Self-Reassurance, the MHI-5 (Mental Health Inventory) and the QCO (Organizational Commitment Questionnaire). Results: The police officers appear to regulate their relationship with the organization through calculative commitment. Self-compassion is associated positively to affective commitment, with mindfulness showing to be the most important competence in this professional group. Self-criticism, in its inadequate self form – which is less corrosive than the hated self form - reveals a positive relationship with calculative commitment, which might imply that staying in the organization may be emotionally negative, may provoke attacks against the self and diminish the affective capacity. However, the self reassurance capacity (reassure self form of self-criticism) may enable the police officers to develop higher levels of organizational commitment and affective commitment, as well. Age, seniority and fewer qualifications seem to support the calculative commitment. Discussion: Through self-compassion police officers may experience a positive and warmth attitude towards the organization. Thus, an intervention program based on self-compassion and mindfulness may stimulate affective and normative commitment, not only preserving and promoting health and the well-being of police officers, but also fostering organizational commitment and mitigating negative effects in the police profession. This approach may contribute to organizational goals’ through the suppression of aversive emotions, decreasing turnover and intention to abandon the organization.
