Intra and Interorganizational Learning Networks and the Implementation of Quality Improvement Initiatives: The Case of a Portuguese Teaching Hospital

Learning has an important position in the development of employees and their expertise. This article focuses on the role and utilization of intra and interorganizational formal and informal learning within different types of learning networks. Specifically, we investigate different types of networks (inter- or intraorganizational) and different types of learning (formal or informal) that can occur within such networks. Our qualitative case study is based on 46 expert interviews involving 49 interviewees, through which we explore how formal and informal learning was used in the development and implementation of quality improvement initiatives at a large public teaching hospital in Portugal. Our analysis suggests that formal and informal learning can take place within different types of learning networks that draw on internal resources as well as on the collaboration with external entities. The article argues that it is important for HRD managers, seeking to support organizational learning, to understand how different types of learning take place, and which features of learning networks support these processes.

Investigating Intra-individual Dietary Changes and Radiocarbon Ages Using High Resolution δ13C, δ15N Isotope Ratios and 14C Ages Obtained From Dentine Increments

Ten medieval permanent teeth were subjected to incremental dentine sectioning and stable isotope analysis to investigate dietary changes in high resolution. In addition to this, eight increments were also selected for 14C measurements to examine possible intra-individual age differences. Results reveal the cessation of weaning, various dietary profiles and in some cases significantly different 14C ages obtained from a single tooth. This case study illustrates how 14C measurements can function as a proxy alongside the commonly used carbon and nitrogen stable isotope values to interpret the diet of past individuals

Civilianizing Civil Conflict: Civilian Defense Militias and the Logic of Violence in Intra-State Conflict

This article examines how civilian defense militias shape violence during civil war. We define civilian defense forces as a sedentary and defensive form of pro-government militia that incumbents often use to harness the participation of civilians during a counterinsurgency campaign. We argue that civilian defense forces reduce the problem of insurgent identification. This leads to a reduction in state violence against civilians. However, we also claim that these actors undermine civilian support for insurgents, which leads to an increase in rebel violence against civilians and overall intensification of conflict. A statistical analysis of government and rebel violence against civilians from 1981 to 2005, and a qualitative assessment of a civilian defense force operating in Iraq from 2005 to 2009, offer strong support for our theoretical claims. These findings provide further insight into pro-government militias and their effects on violence. They also have wider ethical implications for the use of civilian collaborators during civil war.

Life history of turbot in Icelandic waters: Intra- and inter-population genetic diversity and otolith tracking of environmental temperatures

The stock structure of turbot was investigated between samples from S-Norway, the Irish Sea and the Kattegat, using 12 microsatellite loci and compared to the turbot caught in Icelandic waters. Highly significant genetic differentiation was observed between samples from Kattegat and other areas. Significant genetic differentiation was also observed between the Irish Sea sample on one hand and Iceland and S-Norway on the other hand. No significant genetic differentiation was observed between Iceland and S-Norway. Otoliths of 25 turbot, age ranging from 3 to 19 years, were subjected to nearly 300 mass spectrometry determinations of stable oxygen and carbon isotopes. Oxygen isotope composition (δ¹⁸O) in the otolith samples was used to estimate ambient temperature at time of otolith accretion, and yielded estimated temperatures experienced by the turbot ranging from 3 to 15°C. Overall, the genetic analysis indicates panmixia between turbot in Icelandic and Norwegian waters. While the extensive migration of larvae between Norway and Iceland is unlikely, passive drift of turbot larva from other areas (e.g. Ireland) cannot be ruled out. 

O empreendedorismo português na cidade do Recife na primeira metade do século XX

A tese analisa o empreendedorismo do imigrante português na cidade do Recife, Estado de Pernambuco, Nordeste do Brasil, durante a primeira metade do século XX. O foco da tese pode ser assim formulado: teria o imigrante português sido empreendedor nesse cenário de mudança econômica e cultural dos primeiros cinquenta anos do século XX, seja como grupo étnico, seja como pessoa de comportamento empreendedor? O corpus teórico principal é, portanto, derivado do campo do empreendedorismo. É uma pesquisa interdisciplinar, que se ampara nas áreas de história, estudos migratórios, econômicos e organizacionais. De acordo com a literatura consultada, esse tipo de abordagem não é incomum no vasto campo do empreendedorismo (Fillion, 1999 e Martinelli, 2007). À luz dessa visão interdisciplinar, a investigação debruça-se sobre o período referido, resgata a trajetória desse imigrante no país e no Recife e discute sua inserção na economia e sociedade locais. Identifica características do dinamismo econômico comercial existente no período e reconstrói a atmosfera de modernidade que a cidade atravessava no mesmo interregno histórico. Para seu desenvolvimento, a pesquisa se apóia em conteúdos de estudos migratórios, históricos e econômicos porque nesse interregno de tempo, a cidade do Recife estava atravessando a chamada era da modernidade nas esferas econômica, cultural e comportamental. No que diz respeito às questões migratórias, a pertinência é óbvia porque o tema do trabalho tem como alvo o imigrante luso. Já quanto à esfera econômica e ao contexto histórico da modernidade, seus conteúdos são trabalhados como o cenário ou o teatro de operações no qual o ator social, imigrante luso, movimentou-se. O trabalho adota, portanto, o olhar de ourives a procurar e a espiar nos textos, livros, discursos visitados e entrevistas realizadas, eventos ou sinais que conduzam à compreensão e interpretação do comportamento do ator econômico, o imigrante português, na história empresarial da cidade do Recife, na condição de empreendedor. Trata-se, por assim dizer, de uma pesquisa de postura quase arqueológica voltada a procurar achados, materiais e imateriais, que denunciem e permitam a discussão e análise do foco acima citado. Diferentemente de pesquisas recentes a serem referidas no capítulo III que exploram o comportamento empreendedor e o empreendedorismo étnico no cenário dos dias de hoje, o estudo olha pelo retrovisor para quase um século atrás e tenta reconstituir e identificar, na história do imigrante português na cidade, conteúdos empreendedorísticos. Está estruturada em 09 (nove) capítulos. No primeiro, são indicados os objetivos perseguidos, a relevância do estudo sob o ponto de vista teórico e os percalços que a pesquisa atravessou para atingir seu termo final. Faz-se, ainda, uma apresentação detalhada dos demais capítulos do trabalho. No corpo do texto, estão ainda, estampadas imagens que testemunham a presença lusa na cidade e documentam a atmosfera da vida do Recife, no período pesquisado. Os resultados encontrados sinalizam para evidências consistentes de empreendedorismo de natureza étnico lusitana nas cadeias produtivas – conceito a ser definido no 9º capítulo– das indústrias da panificação; de terreno, ferragens e construção; e alimentos em geral. Indica, ainda, comportamento empreendedor do imigrante português em diversas atividades econômicas, desde exportação e importação, cafés, restaurantes até o setor de entretenimento em geral. Acredita-se, destarte, que os resultados alcançados podem aditar contribuições relevantes nos campos referidos acima, bem como indicar novos temas de investigação que desdobrem sugestões formuladas nas considerações finais da investigação.

Androgens and Mating Systems in Fish: Intra- and Inter-specific Analysis

One of the predictions of the ‘challenge hypothesis’ (Wingfield et al., 1990) is that androgen patterns during the breeding season should vary among species according to the parenting and mating system. Here we assess this prediction of the challenge hypothesis both at the intra- and at the inter-specific level. To test the hypothesis at the inter-specific level, a literature survey on published androgen pat- terns from teleost fish with different mating systems was carried out. The results confirm the predicted effect of mating system on andro- gen levels. To test the hypothesis at an intra-specific level, a species with flexible reproductive strategies (i.e. monogamy vs. polygyny), the Saint Peter’s fish was studied. Polygynous males had higher 11- ketotestosterone levels. However, males implanted with methyl-tes- tosterone did not became polygynous and the variation of the ten- dency to desert their pair mates was better explained by the repro- ductive state of the female partner. This result stresses the point that the effects of behaviour on hormones cannot be considered without respect to the social context.

Validation of a fast method for quantification of intra-abdominal and subcutaneous adipose tissue for large-scale human studies

Central obesity is the hallmark of a number of non-inheritable disorders. The advent of imaging techniques such asMRI has allowed for a fast and accurate assessment of body fat content and distribution. However, image analysis continues to be one of the major obstacles to the use of MRI in large-scale studies. In this study we assess the validity of the recently proposed fat–muscle quantitation system (AMRATM Profiler) for the quantification of intra-abdominal adipose tissue (IAAT) and abdominal subcutaneous adipose tissue (ASAT) from abdominal MR images. Abdominal MR images were acquired from 23 volunteers with a broad range of BMIs and analysed using sliceOmatic, the current gold-standard, and the AMRATM Profiler based on a non-rigid image registration of a library of segmented atlases. The results show that there was a highly significant correlation between the fat volumes generated by the two analysis methods, (Pearson correlation r = 0.97, p < 0.001), with the AMRATM Profiler analysis being significantly faster (~3 min) than the conventional sliceOmatic approach (~40 min). There was also excellent agreement between the methods for the quantification of IAAT (AMRA 4.73 ± 1.99 versus sliceOmatic 4.73 ± 1.75 l, p = 0.97). For the AMRATM Profiler analysis, the intra-observer coefficient of variation was 1.6% for IAAT and 1.1% for ASAT, the inter-observer coefficient of variationwas 1.4%for IAAT and 1.2%for ASAT, the intra-observer correlationwas 0.998 for IAAT and 0.999 for ASAT, and the inter-observer correlation was 0.999 for both IAAT and ASAT. These results indicate that precise and accurate measures of body fat content and distribution can be obtained in a fast and reliable form by the AMRATM Profiler, opening up the possibility of large-scale human phenotypic studies.

Low Complexity Intra Mode Selection for Efficient Distributed Video Coding

Motion compensated frame interpolation (MCFI) is one of the most efficient solutions to generate side information (SI) in the context of distributed video coding. However, it creates SI with rather significant motion compensated errors for some frame regions while rather small for some other regions depending on the video content. In this paper, a low complexity Infra mode selection algorithm is proposed to select the most 'critical' blocks in the WZ frame and help the decoder with some reliable data for those blocks. For each block, the novel coding mode selection algorithm estimates the encoding rate for the Intra based and WZ coding modes and determines the best coding mode while maintaining a low encoder complexity. The proposed solution is evaluated in terms of rate-distortion performance with improvements up to 1.2 dB regarding a WZ coding mode only solution.
