Analytical Study of Typographical Errors in OPACS and Corrective Measures

The present study is an attempt to highlight the problem of typographical errors in OPACS. The errors made while typing catalogue entries as well as importing bibliographical records from other libraries exist unnoticed by librarians resulting the non-retrieval of available records and affecting the quality of OPACs. This paper follows previous research on the topic mainly by Jeffrey Beall and Terry Ballard. The word “management” was chosen from the list of likely to be misspelled words identified by previous research. It was found that the word is wrongly entered in several forms in local, national and international OPACs justifying the observations of Ballard that typos occur in almost everywhere. Though there are lots of corrective measures proposed and are in use, the study asserts the fact that human effort is needed to get rid of the problem. The paper is also an invitation to the library professionals and system designers to construct a strategy to solve the issue

Assessment of corrective measures for alleviating slope instabilities in carbonatic Flysch formations: Alicante (SE of Spain) case study

As is well known, in order to select remediation measures to correct or prevent slope instabilities, it is essential to identify and characterize the instability mechanisms. This task is especially complex for heterogeneous rock masses such as Flysch formations. This paper addresses the assessment of corrective measures used in carbonate Flysch formations by classifying and grouping field data reported in an available database in order to associate this data with various instability mechanisms and stratigraphic column types as well as with the corrective measures taken to stabilise them. For this purpose, 194 slopes have been geomechanically characterized, mainly by considering the observed instability mechanisms. The corrective measures that were applied have been evaluated for their suitability and performance, and, if applicable, the causes of their malfunction have been also studied. As a result, some guidelines based on the observed behaviour and the suitability of the correction measure as a function of instability type are proposed for similar slopes.

Indoor air quality in Portuguese archives: a snapshot on exposure levels

Indoor air quality recently entered legislation in Portugal. Several parameters must be evaluated and kept within limits in order to obtain a certification for air quality and energy consumption. Certification parameters were analyzed in two Portuguese archives in order to assess indoor air quality both for people attending or working on these premises and for maintenance of a written heritage that must be retained for future generations. Carbon monoxide (CO) and carbon dioxide (CO2), formaldehyde, and fungal counts were kept within stipulated limits. Relative humidity (RH), volatile organic compounds (VOC), particulate matter (PM10), and ozone (O3) showed values above legislated levels and justified the implementation of corrective measures. In terms of conservation, studies on the limit values are still needed, but according to the available international guidelines, some of the analyzed parameters such as PM10, O3, and RH were also above desirable values. Corrective measures were proposed to these institutions. Although this study was only of a short duration, it proved valuable in assessing potential eventual problems and constitutes the first Portuguese indoor air quality assessment taking into consideration both aspects of an archive such as human health and heritage safekeeping.

Comparação entre diferentes sistemas de avaliação de desempenho

A avaliação do desempenho consiste num instrumento estratégico de extrema importância para a gestão de recursos humanos numa organização, tal como no Exército. Permite criar indicadores ao nível do desempenho dos avaliados ao mesmo tempo que contribui para o diagnóstico e sua melhoria contínua. Ao nível dos órgãos decisores proporciona uma análise das capacidades dos recursos humanos e a sua correta gestão. Foi neste contexto que este trabalho de investigação foi desenvolvido, tendo sido traçado como objetivo, estudar a perceção dos militares avaliadores do Exército Português (EP) quanto aos sistemas de avaliação de desempenho (SAD) em vigor no Exército (SAMME1 e SIADAP2). Usou-se uma metodologia quantitativa e qualitativa e para o efeito foi desenvolvido um questionário, que foi passado aos Coronéis, Tenentes-coronéis, Majores e Capitães, todos eles avaliadores. Esta escolha fundamenta-se pela posição que os mesmos ocupam na cadeia hierárquica, pela experiência e o nível de conhecimentos que possuem sobre os sistemas de avaliação, podendo contribuir com as suas opiniões e sugestões, para a melhoria dos sistemas de avaliação atualmente em vigor no EP. Participaram no presente estudo 259 Oficiais avaliadores que responderam a um questionário online lançado na internet. Os principais resultados obtidos permitem concluir que o SAMME assume maior relevância e menor subjetividade que o SIADAP. Foi ainda observada a necessidade de implementar algumas medidas corretivas nos dois sistemas de avaliação em estudo, tais como: implementar no SAMME a autoavaliação e criar objetivos; no SIADAP, acabar com as quotas de 5% para a atribuição da classificação de desempenho excelente aos avaliados; Observou-se ainda que o avaliador tem uma importância

Comparison of Aspergillus species-complexes detected in different environmental settings

Purpose: Samples from different environmental sources were screened for the presence of Aspergillus, and the distribution of the different species-complexes was determined in order to understand differences among that distribution in the several environmental sources and which of these species complexes are present in specific environmental settings. Methods: Four distinct environments (beaches, poultries, swineries and hospital) were studied and analyzed for which Aspergillus complexes were present in each setting. After plate incubation and colony isolation, morphological identification was done using macro- and microscopic characteristics. The universal fungal primers ITS1 and ITS4 were used to amplify DNA from all Aspergillus isolates, which was sequenced for identification to species complex level. SPSS v15.0 for Windows was used to perform the statistical analysis. Results: Thirty-nine isolates of Aspergillus were recovered from both the sand beach and poultries, 31 isolates from swineries, and 80 isolates from hospital environments, for a total 189 isolates. Eleven species complexes were found total. Isolates belonging to the Aspergillus Versicolores species-complex were the most frequently found (23.8%), followed by Flavi (18.0%), Fumigati (15.3%) and Nigri (13.2%) complexes. A significant association was found between the different environmental sources and the distribution of the several species-complexes (p<0.001); the hospital environment had a greater variability of species-complexes than other environmental locations (10 in hospital environment, against nine in swine, eight in poultries and seven in sand beach). Isolates belonging to Nidulantes complex were detected only in the hospital environment, whereas the other complexes were identified in more than one setting. Conclusion: Because different Aspergillus complexes have different susceptibilities to antifungal drugs, and different abilities in producing mycotoxins, knowledge of the species-complex epidemiology for each setting may allow preventive or corrective measures to be taken toward decreasing professional workers or patient exposure to those agents.

Diagnóstico de higiene e segurança no trabalho: proposta de medidas correctivas

O trabalho que é de seguida apresentado foi desenvolvido durante o estágio efectuado no Instituto de Desenvolvimento e Inovação Tecnológica (IDIT), tendo em vista a realização de um projecto de fim de Mestrado em Engenharia Química no ramo de Tecnologias de Protecção Ambiental. O projecto teve como principal objectivo a elaboração de um diagnóstico de Segurança, Higiene e Saúde no Trabalho tendo por base as medições de factores de riscos, efectuadas numa empresa pertencente ao sector da alimentação, e o seu respectivo enquadramento legal. A realização deste trabalho consistiu na avaliação de factores físicos e químicos presentes em todas as actividades industriais, que podem constituir riscos para a higiene, saúde e segurança dos trabalhadores. Os factores considerados neste estudo foram: o ruído, a iluminância, as vibrações, o ambiente térmico e os contaminantes químicos. Ao longo do trabalho são apresentados os resultados obtidos nas avaliações efectuadas e a sua análise, que permitiu o conhecimento das condições de trabalho, para as diversas actividades desempenhadas na empresa, revelando as não concordâncias dos factores estudados. Segundo os resultados obtidos conclui-se que a empresa apresenta condições de Higiene, Saúde e Segurança bastantes satisfatórias, apresentando apenas algumas não conformidades, particularmente nos níveis de pressão sonora. No entanto, estas não conformidades podem ser contornadas com a aplicação de medidas correctivas previstas no enquadramento legal que abrange cada factor avaliado. A escassez de tempo não permitiu a elaboração de um diagnóstico de HST completo, uma vez que, uma análise de risco completa necessita de um estudo mais aprofundado na área e uma prática considerável, que não foi possível adquirir até então.

Molecular screening of 246 Portuguese Aspergillus isolates among different clinical and environmental sources

Clinical and environmental samples from Portugal were screened for the presence of Aspergillus and the distributions of the species complexes were determined in order to understand how their distributions differ based on their source. Fifty-seven Aspergillus isolates from clinical samples were collected from 10 health institutions. Six species complexes were detected by internal transcribed spacer sequencing; Fumigati, Flavi, and Nigri were found most frequently (50.9%, 21.0%, and 15.8%, respectively). β-tubulin and calmodulin sequencing resulted in seven cryptic species (A. awamorii, A. brasiliensis, A. fructus, A. lentulus, A. sydowii, A. tubingensis, Emericella echinulata) being identified among the 57 isolates. Thirty-nine isolates of Aspergillus were recovered from beach sand and poultry farms, 31 from swine farms, and 80 from hospital environments, for a total 189 isolates. Eleven species complexes were found in these 189 isolates, and those belonging to the Versicolores species complex were found most frequently (23.8%). There was a significant association between the different environmental sources and distribution of the species complexes; the hospital environment had greater variability of species complexes than other environmental locations. A high prevalence of cryptic species within the Circumdati complex was detected in several environments; from the isolates analyzed, at least four cryptic species were identified, most of them growing at 37ºC. Because Aspergillus species complexes have different susceptibilities to antifungals, knowing the species-complex epidemiology for each setting, as well as the identification of cryptic species among the collected clinical isolates, is important. This may allow preventive and corrective measures to be taken, which may result in decreased exposure to those organisms and a better prognosis.
