Communication in organizations and 360-degree evaluation: what is the relationship between the two concepts?

The performance appraisal has a very important role in the strategic objectives of the organization, because it contributes to its efficacy (Aguinis, 2007). However, some limitations of top-down performance appraisal like the subjectivity have been proposed other evaluations, like 360-degree evaluation (Kondrasuk, 2012). This is a specific evaluation that considers more than one appraiser (Brutus & Gorriti, 2005). The purpose of this research is to know if the application of 360-degree evaluation influences organizational communication. We conducted a qualitative exploratory study through the interviews with experts. The results that will be presented are still preliminary and have theoretical and practical applications. In general, we conclude that 360-degree evaluation could be advantageous for organizational communication (e.g. active voice of employees; symmetrical and bi-directional communication).info:eu-repo/semantics/publishedVersio

Acute Myocardial Infarction Associated with Anomalous Origin of Coronary Arteries (a Rare Case of Origin of the Left Coronary Artery From the Ostium of the Right Coronary Artery)

A origem da artéria coronária esquerda a partir do ostio ou do segmento proximal da artéria coronária direita é uma anomalia congénita rara (0,03 a 0,4%), e um achado angiográfico pouco comum (0,6 a 1,3%) (artéria coronária única). A anomalia congénita coronária mais frequente é a origem separada da artéria descendente anterior e da artéria circunflexa no seio coronário esquerdo. A segunda anomalia mais comum é a origem da artéria circunflexa no seio coronário direito. Descrevemos um caso de enfarte agudo do miocárdio com localização infero lateral, que evoluiu com choque cardiogénico e disfunção ventricular esquerda graves, após angioplastia primária de oclusão proximal da artéria coronária direita, e em que não foi possível cateterizar a artéria coronária esquerda por inexistência de ostio no seio coronário esquerdo. Destaca-se o papel importante das novas técnicas de imagem, nomeadamente da angio-TC das coronárias, na identificação das anomalias congénitas das artérias coronárias

Asymptotic Flatness in Rainbow Gravity

A construction of conformal infinity in null and spatial directions is constructed for the Rainbow-flat space-time corresponding to doubly special relativity. From this construction a definition of asymptotic DSRness is put forward which is compatible with the correspondence principle of Rainbow gravity. Furthermore a result equating asymptotically flat space-times with asymptotically DSR spacetimes is presented.Comment: 11 page

Produção e distribuição sazonal de litter em áreas de caatinga sob diferentes manejos.

Resumo: O litter compreende restos vegetais e animais. Sua presença confere proteção ao solo evitando o efeito negativo das enxurradas, mantendo a temperatura e estrutura do solo. Este trabalho objetivou quantificar a produção e distribuição de litter em áreas de caatinga raleada e não manipulada. Três áreas foram utilizadas: raleada para fins pastoris, raleada para fins apícolas e não manipulada. A produção foi obtida a partir do lançamento de molduras e 1,0x0,25m em diferentes épocas do ano de 2012. O litter foi fracionado manualmente em seus componentes e determinados suas proporções da massa total. A área não manipulada apresentou maior produção de litter, 5.714,35 Kg/ha enquanto a área de Caatinga raleada para fins apícolas a menor produção, 3.921,21 Kg/ha. A miscelânea foi a fração do litter que apresentou maior representatividade chegando a responder por 50% de toda a produção. A produção de litter de uma área nativa pode ser semelhante a uma área raleada. A produção tem relação direta com a precipitação. Esta mostrou sazonalidade na produção total, contrariando suas frações que mantiveram-se equilibrados durante todo o ano. [Seasonal production and distribution of litter in different areas under caatinga managements]. Abstract: The litter includes plant and animal remains. Its presence confers protection to the ground avoiding the negative effect of floods, keeping the temperature and soil structure. This study aimed to quantify the production and distribution of litter in areas of thinned caatinga and not manipulated. Three areas were used for grazing purposes thinned, thinned for apiculture and not manipulated. The production was obtained from the launch of frames and 1.0 x0, 25m at different times of the year 2012. The litter was manually fractionated into its components, and certain proportions of their total mass. The area had not manipulated greater production of litter, 5714.35 kg / ha while the area of Caatinga thinned for apiculture lower production, 3921.21 kg / ha. The smorgasbord was the fraction of the litter with the highest representation coming to account for 50% of all production. The production of litter from an area native can be similar to a thinned area. The production is directly related to precipitation. The total production of litter showed seasonality, contradicting its fractions which remained balanced throughout the year

Uso do orçamento forrageiro em abordagem participativa para produção de caprinos no bioma caatinga.

Resumo: O uso do orçamento forrageiro (OF) com enfoque participativo visa envolver agricultores no processo de construção de técnicas que possam ser facilmente utilizadas para o manejo sustentável dos recursos naturais. O objetivo deste trabalho foi testar OF como instrumento para planejamento do rebanho caprino. A experiência foi conduzida em área individual de 11ha, em assentamento no sertão do Apodi (RN). A área foi composta por cultivo de algodão agroecológico, sistema agrossilvipastoril e pasto nativo. O rebanho foi de vinte animais. OF foi realizado em três etapas: levantamento da produção de massa seca total de forragem disponível, avaliação do efetivo animal e planejamento. As informações do levantamento determinaram o tempo máximo de uso da área para manter as metas de ganho de peso para cabritos e manutenção de peso dos adultos. As práticas agroecológicas aumentaram a oferta de forragem. Houve manutenção do peso das cabras e ganhos de peso nas novilhas. Os cabritos ganharam peso de forma linear. O monitoramento permitiu confirmar que a ferramenta do orçamento forrageiro foi efetiva em auxiliar no planejamento zootécnico do rebanho no semiárido. [Forage budget on participatory approach to goat production in caatinga biome]. Abstract: Forage budget (FB) using participatory approach had been used to include smallholders in technology generation process and improving transfer technology for others. This research was carried out to test FB as a tool to make a planning for goat production system in Brazilian semi arid land. In an individual settlement area about 11 ha was implemented it. There were agroecological cotton system, agrossilvipastoral and native vegetation there. There were 20 animal in the area. FB was implemented in three phases: quantification of forage biomass total and available, herd evaluation and planning. It was determinate a maximum time to keep animal in the land using information from planning that preview as goal keep weight in goats and gain weight in kids. Ecological practices improved amount of forage. There was possible keep weight in goats. Young goats had gained weight. All kids gained weight during experimental period. Monitoring zootechnical aspects were effective to ensure forage budget like a good tool to help smallholders in sustainable planning use natural resources

Generalized coordinates on the phase space of Yang-Mills theory

We study the suitability of complex Wilson loop variables as (generalized) coordinates on the physical phase space of $SU(2)$-Yang-Mills theory. To this end, we construct a natural one-to-one map from the physical phase space of the Yang-Mills theory with compact gauge group $G$ to a subspace of the physical configuration space of the complex G^\C-Yang-Mills theory. Together with a recent result by Ashtekar and Lewandowski this implies that the complex Wilson loop variables form a complete set of generalized coordinates on the physical phase space of $SU(2)$-Yang-Mills theory. They also form a generalized canonical loop algebra. Implications for both general relativity and gauge theory are discussed.Comment: TeX, 11pp, revised version (minor clarifications added, Comment after (2.9) inserted); to appear in Class. Quant.

Influence of EBR on the structural resistance of RC slabs under quasi-static and blast loading: Experimental testing and numerical analysis

Flexural strengthening of reinforced concrete (RC) structures with externally bonded reinforcement (EBR) using carbon fibre-reinforced polymers (CFRP) has in recent years received increased interest from specialists, particularly when dealing with protective structures against terrorist or accidental blast loading. Although a significant number of studies have been conducted on the failure modes of the bonded interface for quasi -static conditions, there is still limited published research on the effects of blast loading. In this paper, RC slabs externally strengthened with CFRP are tested in three-point bending as well as subjected to blast loading. The behaviour of the tested specimens under both loading regimes is evaluated with special focus on the mechanisms that lead to the disruption of the CFRP. It was found that the debonding of the CFRP was caused, in both cases, by the fracture and separation of a thin layer of concrete in the near vicinity of the bonded interface. However, the mechanisms that lead to this failure differ. A numerical model was developed and simulations performed using the finite element (FE) code LS-DYNA to investigate the validity of commonly used simplifications on the modelling of the interface in both cases. It was found that although the modelling technique used to represent the disruption of CFRP under quasi-static conditions provide accurate results, it does not return accurate predictions of the debonding of CFRP under blast loading
