Relação das Perceções de Justiça Organizacional na Avaliação de Desempenho

A avaliação de desempenho é utilizada pelas organizações para aprovisionar os programas de desenvolvimento, distribuição de recompensas e, também, para fornecer uma perceção de justiça aos trabalhadores em relação às suas tarefas, aos postos de trabalho, à organização, às chefias e aos departamentos. É um processo contínuo através do qual a comunicação é afetivamente feita entre as chefias e os funcionários de uma organização. O objetivo deste trabalho é explorar o sistema de avaliação de desempenho no âmbito da justiça organizacional, e, mais especificamente, dos três tipos de justiça, designadamente, a justiça distributiva, a justiça procedimental e a justiça interacional. Assim, pretende-se conhecer a perceção dos militares em relação à distribuição de resultados na avaliação de desempenho, à forma como se processa a avaliação de desempenho e à dinâmica das relações na avaliação de desempenho. A amostra deste estudo foram 231 militares, das categorias de Oficiais e Sargentos, de várias especialidades, da Força Aérea Portuguesa. Os dados foram recolhidos através de um questionário disponibilizado a todos os militares dos Quadros Permanentes da Força Aérea. Pelos resultados obtidos, observou-se que há perceção de justiça organizacional no sistema de avaliação do mérito nos militares da Força Aérea, com coeficientes positivos em todas as dimensões de justiça. Destaca-se a justiça interpessoal, seguida da distributiva, procedimental, e informacional. Verifica-se ainda que as perceções de justiça procedimental e informacional estão muito próximas.

Continuous CO2/CH4/CO measurements (2012–2014) at Beromünster tall tower station in Switzerland

The understanding of the continental carbon budget is essential to predict future climate change. In order to quantify CO₂ and CH₄ fluxes at the regional scale, a measurement system was installed at the former radio tower in Beromünster as part of the Swiss greenhouse gas monitoring network (CarboCount CH). We have been measuring the mixing ratios of CO₂, CH₄ and CO on this tower with sample inlets at 12.5, 44.6, 71.5, 131.6 and 212.5 m above ground level using a cavity ring down spectroscopy (CRDS) analyzer. The first 2-year (December 2012–December 2014) continuous atmospheric record was analyzed for seasonal and diurnal variations and interspecies correlations. In addition, storage fluxes were calculated from the hourly profiles along the tower. The atmospheric growth rates from 2013 to 2014 determined from this 2-year data set were 1.78 ppm yr⁻¹, 9.66 ppb yr⁻¹ and and -1.27 ppb yr⁻¹ for CO₂, CH₄ and CO, respectively. After detrending, clear seasonal cycles were detected for CO₂ and CO, whereas CH₄ showed a stable baseline suggesting a net balance between sources and sinks over the course of the year. CO and CO₂ were strongly correlated (r² > 0.75) in winter (DJF), but almost uncorrelated in summer. In winter, anthropogenic emissions dominate the biospheric CO₂ fluxes and the variations in mixing ratios are large due to reduced vertical mixing. The diurnal variations of all species showed distinct cycles in spring and summer, with the lowest sampling level showing the most pronounced diurnal amplitudes. The storage flux estimates exhibited reasonable diurnal shapes for CO₂, but underestimated the strength of the surface sinks during daytime. This seems plausible, keeping in mind that we were only able to calculate the storage fluxes along the profile of the tower but not the flux into or out of this profile, since no Eddy covariance flux measurements were taken at the top of the tower.

Rock magnetic records and geochemical methods of sediment cores off NW Africa

Two gravity cores retrieved off NW Africa at the border of arid and subtropical environments (GeoB 13602-1 and GeoB 13601-4) were analyzed to extract records of Late Quaternary climate change and sediment export. We apply End Member (EM) unmixing to 350 acquisition curves of isothermal remanent magnetization (IRM). Our approach enables to discriminate rock magnetic signatures of aeolian and fluvial material, to determine biomineralization and reductive diagenesis. Based on the occurrence of pedogenically formed magnetic minerals in the fluvial and aeolian EMs, we can infer that goethite formed in favor to hematite in more humid climate zones. The diagenetic EM dominates in the lower parts of the cores and within a thin near-surface layer probably representing the modern Fe**2+/Fe**3+ redox boundary. Up to 60% of the IRM signal is allocated to a biogenic EM underlining the importance of bacterial magnetite even in siliciclastic sediments. Magnetosomes are found well preserved over most of the record, indicating suboxic conditions. Temporal variations of the aeolian and fluvial EMs appear to faithfully reproduce and support trends of dry and humid conditions on the continent. The proportion of aeolian to fluvial material was dramatically higher during Heinrich Stadials, especially during Heinrich Stadial 1. Dust export from the Arabian-Asian corridor appears to vary contemporaneous to increased dust fluxes on the continental margin of NW Africa emphasizing that melt-water discharge in the North Atlantic had an enormous impact on atmospheric dynamics.

Using clinical indicators in a quality improvement programme targeting cardiac care

Rationale. The Brisbane Cardiac Consortium, a quality improvement collaboration of clinicians from three hospitals and five divisions of general practice, developed and reported clinical indicators as measures of the quality of care received by patients with acute coronary syndromes or congestive heart failure. Development of indicators. An expert panel derived indicators that measured gaps between evidence and practice. Data collected from hospital records and general practice heart-check forms were used to calculate process and outcome indicators for each condition. Our indicators were reliable (kappa scores 0.7-1.0) and widely accepted by clinicians as having face validity. Independent review of indicator-failed, in-hospital cases revealed that, for 27 of 28 process indicators, clinically legitimate reasons for withholding specific interventions were found in

Differences in sharing knowledge interpersonally and via databases: The role of evaluation apprehension and perceived benefits

Knowledge sharing is an essential component of effective knowledge management. However, evaluation apprehension, or the fear that your work may be critiqued, can inhibit knowledge sharing. Using the general framework of social exchange theory, we examined the effects of evaluation apprehension and perceived benefit of knowledge sharing ( such as enhanced reputation) on employees' knowledge sharing intentions in two contexts: interpersonal (i.e., by direct contact between two employees) and database (i.e., via repositories). Evaluation apprehension was negatively associated with knowledge sharing intentions in both contexts while perceived bene. it was only positively associated with knowledge sharing intentions in the database context. Moreover, compared to the interpersonal context, evaluation apprehension was higher and knowledge sharing lower in the database context. Finally, the negative effects of evaluation apprehension upon knowledge sharing intentions were worse when perceived benefits were low compared to when perceived benefits were high.

Cyber-rigging click-through rates: Exploring the ethical dimensions

Click-through rate is considered a very important metric and a key performance indicator of the success of online advertising and is the most frequently used measure to gauge the effectiveness of banner advertising. Marketers also use click-through rates in arriving at performance measurement activities such as the calculation of 'customer life time value' and 'customer acquisition cost'. Click-through is the second most frequently used banner ad pricing method after cost per thousand impressions. Online advertising is facing a new form of challenge – the artificial inflation of click-through rates. We call this practice 'cyber-rigging'. The objective of this paper is to explore the ethical dimensions of cyber-rigging through application of ethical principles and theories.

ENTRE NÚMEROS E PALAVRAS: DIFERENÇAS QUE COLIDEM NO FRACASSO ESCOLAR

Esta dissertação - Entre números e palavras: diferenças que colidem no fracasso escolar - procura observar, inicialmente, as diretrizes curriculares e os sistemas avaliativos, com ênfase sobre o Currículo Oficial, instituído em 2008, e o Sistema de Avaliação do Rendimento Escolar (SARESP) do Estado de São Paulo, para, posteriormente, buscar compreender as relações que se estabelecem quando observados pelo discurso dos professores, que em sala de aula são o ponto de contato entre o currículo e os alunos. Para tanto, além da análise dos documentos curriculares e dos sistemas de avaliação oficiais, referendamo-nos em pressupostos teóricos relacionados ao campo curricular, tendo como principal viés os conceitos de Capital Cultural e Habitus desenvolvidos por Pierre Bourdieu. A partir destas discussões e conceitos se organizam as entrevistas realizadas com professores de Língua Portuguesa do 9º ano do ensino fundamental da rede pública do Estado de São Paulo, em que buscamos problematizar o Currículo Oficial, as metas e resultados de desempenho estabelecidos pelo SARESP, as relações de poder e ideologia presentes nas diretrizes curriculares no encontro com o Capital Cultual dos alunos. Deste modo, este estudo observa um amplo conjunto de práticas que mobilizam as ações educativas, com reflexos sobre o funcionamento da escola, bem como sobre os professores e os alunos; bem como, problematiza a constituição de diretrizes curriculares, o estabelecimento de currículos oficiais e sua unicidade, os resultados advindos das avaliações sistêmicas, as relações de poder e ideologias que atravessam os documentos oficiais e sua influência sobre a formação escolar dos alunos.

Managing the quality, value and impact of academic libraries: the role of external standards

Purpose – The purpose of this paper is to explore the role and relevance of external standards in demonstrating the value and impact of academic library services to their stakeholders. Design/methodology/approach – Two UK standards, Charter Mark and Customer Service Excellence, are evaluated via an exploratory case study, employing multiple data collection techniques. Methods and results of phases 1-2 of a three phase research project are outlined. Findings – Despite some limitations, standards may assist the manager in demonstrating the value, impact and quality of academic libraries in a recessional environment. Active engagement and partnership with customers is imperative if academic libraries are to be viewed as vital to their parent organisations and thus survive. Originality/value – This paper provides a systematic evaluation of the role of external accreditation standards in measuring academic library service value and impact.

The UK productivity gap in the service sector: do management practices matter?

Purpose – This paper aims to contribute to the debate on the drivers of the productivity gap that exists between the UK and its major international competitors. Design/methodology/approach – From the macro perspective the paper explores the quantitative evidence on the productivity differentials and how they are measured. From the micro perspective, the article explores the quantitative evidence on the role of management practices claimed to be a key determinant in promoting firm competitiveness and in bridging the UK gap. Findings – This study suggests that management practices are an ambiguous driver of firm productivity and higher firm performance. On the methodological side, qualitative and subjective measures of either management practices or firm performance are often used. This makes the results not comparable across studies, across firms or even within firms over time. Productivity and profitability are often and erroneously interchangeably used while productivity is only one element of firm performance. On the other hand, management practices are multi-dimensional constructs that generally do not demonstrate a straightforward relationship with productivity variables. To assume that they are the only driver of higher productivity may be misleading. Moreover, there is evidence of an inverse causal relationship between management practices and firm performance. This calls into question most empirical results of the extant literature based on the unidirectional assumption of direct causality between management practices and firm performance. Research limitations/implications – These and other issues suggest that more research is needed to deepen the understanding of the UK productivity gap and more quantitative evidence should be provided on the way in which management practices contribute to the UK competitiveness. Their impact is not easily measurable due to their complexity and their complementary nature and this is a fertile ground for further research. Originality/value – This paper brings together the evidence on the UK productivity gap and its main drivers, provided by the economics, management and performance measurement literature. This issue scores very highly in the agenda of policy makers and academics and has important implications for practitioners interested in evaluating the impact of managerial best practices.

Intelligence agents (knowledge management)

Reports some insights into knowledge management (KM) derived from UK one-day workshops with six businesses, three non-profits and one public sector organization. Lists the four questions posed to participants and discusses the themes which emerged, e.g. the need for a KM strategy to make raw information more useable, KM performance measurement etc. Stresses the need for commitment from a top-level champion and a wide range of employees to make this work and identifies three types of solutions for improving KM strategy: technological (e.g. databases and intranets), people (e.g. motivation, retention, training and networking) and processes (e.g. procedural instructions and balancing formal/informal knowledge sharing methods). Finds that accountants and senior managers do not generally see KM as very important but argues that management accountants are suitable knowledge champions who could develop explicit links between KM and organizational performance.

High stability interleaved fibre Michelson interferometer for on-line precision displacement measurements

A self-reference fiber Michelson interferometer measurement system, which employs fiber Bragg gratings (FBGs) as in-fiber reflective mirrors and interleaves together two fiber Michelson interferometers that share the common-interferometric-optical path, is presented. One of the fiber interferometers is used to stabilise the system by the use of an electronic feedback loop to compensate the influences resulting from the environmental disturbances, while the other one is used to perform the measurement task. The influences resulting from the environmental disturbances have been eliminated by the compensating action of the electronic feedback loop, this makes the system suitable for on-line precision measurement. By means of the homodyne phase-tracking technique, the linearity of the measurement results of displacement measurements has been very high.
