Competency Management Articulation for Human Resources

In recent years the approach to competences has gained great popularity due to process and organizational reengineering need. Taking opportunity on some recent work in this area dealing challenges that human resources face to develop planning training, I intend to identify several guidelines to develop a future architecture in a practical implementation. At this article is presented the concept development of competency management.

Personalidade e agressividade : um estudo em militares de protecção e socorro

RESUMO: A protecção e socorro é das missões mais recentes na instituição militar em Portugal, nomeadamente a intervenção em catástrofes. As características têm um papel decisivo, pois podem condicionar de forma determinante o sucesso da missão. O discernimento do indivíduo é imperativo nas situações, não pode haver erros, pois os custos humanos e económicos são demasiado elevados. Foi estudada uma amostra de 535 militares oportugueses de uma força de elite helitransportada que actua em catástrofes, em que a média de idades é de 28 anos (DP=4,4), tendo o militar mais novo 20 anos e o mais velho 49 anos. O escalão etário mais representado é o escalão dos 26-30 anos que compreende 52,7% desta força militar operacional. Para esta investigação utilizámos como medidas de avaliação o Inventário de Personalidade Neo revisto, NEOPI-R (Costa & McCrae 1992), o Questionário de Agressividade, AQ (Buss & Perry, 1992)e a Escala de Desejabilidade Social de Paulhus, PDS (Paulhus, 1998) para aceder à relação entre personalidade, agressividade e desejabilidade social em militares de protecção e socorro. Conclui-se que os militares de protecção e socorro demonstram valores elevados de conscienciosidade e valores mais baixos ao nível do domínio do neuroticismo. Demonstraram resultados mais elevados na dimensão Gestão da imagem e mais baixos na dimensão de Auto apresentação favorável. Apresentam ainda níveis de agressividade física bastante elevados e níveis de irritabilidade mais baixos. ABSTRACT: Rescue and protection is one of the latest missions in the Military Corps in Portugal, namely the Disaster Intervention. It depends directly on individual characteristics such as personality and how the military deal with extreme and tension situations. These characteristics have a decisive role, as they contribute to the success of decisive missions. The discernment of the individual is imperative in situations where there can be mistakes, because the human and economic costs are too high. The studied sample consisted of 535 soldiers of the military Portuguese Protection and Rescue, an elite force heliborne, where the average age is 28 years (DP=4,4 years), having the younger military 20 years and the oldest 49 years. The age group most represented is the level 26-30 years comprising 52.7% of this military operational force. In order to make this investigation we used the following measures : the Neo Personality Inventory Revised, NEOPI-R (costa & McCrae, 1992), the Agression Questionnaire, AQ (Buss & Perry, 1992), and the Paulhus Deception Scale, PDS (Paulhus, 1998) to access the relationship between personality, aggressiveness and social desirability in Rescue and Protection Military. It is concluded that Rescue and Protection military show high values of conscientiousness and lower values of neuroticism. They also show higher scores on the impression management and lower scores on the Self-Deceptive Enhancement dimension. Subjects also present high levels of physical aggression and lower levels of anger.

Capacity Enhancement Using MIMO Antenna Arrays in Realistic Macro-Cellular Urban Environment

In MIMO systems the antenna array configuration in the BS and MS has a large influence on the available channel capacity. In this paper, we first introduce a new Frequency Selective (FS) MIMO framework for macro-cells in a realistic urban environment. The MIMO channel is built over a previously developed directional channel model, which considers the terrain and clutter information in the cluster, line-of-sight and link loss calculations. Next, MIMO configuration characteristics are investigated in order to maximize capacity, mainly the number of antennas, inter-antenna spacing and SNR impact. Channel and capacity simulation results are presented for the city of Lisbon, Portugal, using different antenna configurations. Two power allocations schemes are considered, uniform distribution and FS spatial water-filling. The results suggest optimized MIMO configurations, considering the antenna array size limitations, specially at the MS side.

SAR determination and influence of the human head in the radiation of a mobile antenna for two different frequencies

The big proliferation of mobile communication systems has caused an increased concern about the interaction between the human body and the antennas of mobile handsets. In order to study the problem, a multiband antenna was designed, fabricated and measured to operate over two frequency sub bands 900 and 1800 MHz. After that, we simulated the same antenna, but now, in the presence of a human head model to analyze the head's influence. First, the influence of the human head on the radiation efficiency of the antenna has been investigated as a function of the distance between the head and the antenna and with the inclination of the antenna. Furthermore, the relative amount of the electromagnetic power absorbed in the head has been obtained.

Tuning Iris Recognition for Noisy Images

The use of iris recognition for human authentication has been spreading in the past years. Daugman has proposed a method for iris recognition, composed by four stages: segmentation, normalization, feature extraction, and matching. In this paper we propose some modifications and extensions to Daugman's method to cope with noisy images. These modifications are proposed after a study of images of CASIA and UBIRIS databases. The major modification is on the computationally demanding segmentation stage, for which we propose a faster and equally accurate template matching approach. The extensions on the algorithm address the important issue of pre-processing that depends on the image database, being mandatory when we have a non infra-red camera, like a typical WebCam. For this scenario, we propose methods for reflection removal and pupil enhancement and isolation. The tests, carried out by our C# application on grayscale CASIA and UBIRIS images show that the template matching segmentation method is more accurate and faster than the previous one, for noisy images. The proposed algorithms are found to be efficient and necessary when we deal with non infra-red images and non uniform illumination.

Human cryptosporidiosis: detection of specific antibodies in the serum by an indirect immunofluorescence

Cryptosporidium sp., a coccidian parasite usually found in the faeces of cattle, has been recently implicated as an agent of human intestinal disease, mainly in immunocompromised patients. In the study realized, by an indirect immunofluorescence technique, specific immunoglobulins (IgG and IgM) have been demonstrated in human serum against Cryptosporidium oocysts. Purified oocysts were used as antigens in the indirect immunofluorecence assay. After analyzing this test in sera from selected groups of patients, the frequency of both specific IgG and IgM of immunocompetent children who were excreting oocysts in their faeces was 62% and in children with negative excretion of oocysts was 20% and 40%, respectively. In adults infected with the human immunodeficiency virus (HIV) and who were excreting Cryptosporidium in their stools, the frequency was 57% for IgG but only 2% for IgM. Twenty three percent of immunocompromised adults with not determined excretion of oocysts in their stools had anti-Cryptosporidium IgG in their sera. Children infected with human immunodeficiency virus had no IgM and only 14% had IgG detectable in their sera. The indirect immunoflorescence assay, when used with other parasitological techniques appears to be useful for retrospective population studies and for diagnosis of acute infection. The humoral immune response of HIV positive patients to this protozoan agent needs clarification.

Human case of gastric infection by a fourth larval stage of Pseudoterranova decipiens (Nematoda, Anisakidae)

Only three cases of human infection by anisakid nematodes have been reported in Chile since 1976. In the present case, an anisakid worm, identified as a fourth-stage Pseudoterranova decipiens larva, was removed with a gastroendoscopic biopsy clipper from the stomach of a 45 year-old man from southern Chile. The patient, who presented acute epigastric pain and a continuous sensation of having an empty stomach, reported having eaten smoked fish. The worm was fixed in 70% ethanol and cleaned in lactophenol for morphological study. The morphometric characteristics of the worm are described and drawn. Anisakid larvae in fish flesh can be killed by freezing or cooking.

New cases of human diphyllobothriosis in Patagonia, Argentine

The purpose of the paper is to describe 4 new cases of human diphyllobothriosis in Patagonia, Argentine. Adult parasites recovered were submitted to morphological and histological analyses for taxonomic identification. The etiological agent found was always Diphyllobothrium latum and all the cases were autochthonous. These data combined with previous information make the number of autochthonous human cases of diphyllobothriosis registered in Argentina increase to 18.

Image enhancement for digital radiography

Once in a digital form, a radiographic image may be processed in several ways in order to turn the visualization an act of improved diagnostic value. Practitioners should be aware that, depending on each clinical context, digital image processing techniques are available to help to unveil visual information that is, in fact, carried by the bare digital radiograph and may be otherwise neglected. The range of visual enhancement procedures includes simple techniques that deal with the usual brightness and contrast manipulation up to much more elaborate multi-scale processing that provides customized control over the emphasis given to the relevant finer anatomical details. This chapter is intended to give the reader a practical understanding of image enhancement techniques that might be helpful to improve the visual quality of the digital radiographs and thus to contribute to a more reliable and assertive reporting.
