Prevalence and Forms of Bullying among Business Professionals: A Comparison of Two Different Strategies for Measuring Bullying

The aim of this study was to analyse the prevalence and forms of workplace bullying among business professionals holding predominantly managerial or expert positions. A cross-sectional survey study was conducted among Finnish professionals with a university degree in business studies. In the study two different strategies for measuring bullying were used and compared. When provided a definition of bullying, 8.8% of the respondents reported that they had at least occasionally been bullied during the past 12 months. However, when using a slightly modified version of the Negative Acts Questionnaire (Einarsen & Hoel 2001), containing a list of 32 predefined negative and potentially harassing acts, as many as 24.1% of the respondents reported that they had been subjected to at least one of the negative acts on a weekly basis. The respondents had experienced predominantly work-related negative acts, e.g. that their opinions and views were ignored, that they were given unreasonable deadlines or that information was withheld. Although the prevalence rates reported with the two strategies varied considerably, there was still consistency between the two strategies in the sense that those who had classified themselves as bullied also reported higher exposure rates to almost all of the negative acts included.

The Quest for Well-being in Growth Industries: Contexts, Research Design and Methodological Development

This Working Paper reports the background to the first stage of the ongoing research project, The Quest for Well-being in Growth Industries: A Collaborative Study in Finland and Scotland, conducted under the auspices of the Academy of Finland research programme The Future of Work and Well-being (2008-2011). This collaborative project provides national and transnational data, analysis and outputs. The study is being conducted in the Department of Management and Organisation, Hanken School of Economics, Finland, in collaboration with Glasgow Caledonian University, University of East London, Heriot-Watt University and Reading University, UK. The project examines policies and practices towards the enhancement of work-related well-being in growth industries, and contradictory pressures and tensions posed in this situation. The overall aim is to evaluate the development, implementation and use of work-related well-being policies in four selected growth industries. These sectors – electronics, care, finance and accounting, and tourism – have been selected on the basis of European Union and national forecasts, and demographic and socio-economic trends in employment. In this working paper we outline the background to the research study, the initial research plan, and how the survey of employers has been constructed. The working paper concludes with a brief discussion of general ongoing research issues arising in the project.

Process of burnout: structure, antecedents, and consequences

The major changes that have been witnessed in today's workplaces are challenging the mental well-being of employed people. Stress and burnout are considered to be modern epidemics, and their importance to physical health and work ability has been acknowledged world-wide. The aim of the thesis was to study the concept of burnout as a process proceeding from its antecedents, through the development of the syndrome, and to its outcomes. Several work-related factors considered antecedents of burnout were studied in different occupational groups. The syndrome of burnout is seen as consisting of three dimensions - exhaustion, cynicism and lack of professional efficacy - and different alternatives for the sequential development of these dimensions were tested. Furthermore, several indicators of the severely detrimental health and work ability outcomes of burnout were investigated in a longitudinal study design. The research questions were as follows. 1) Is burnout, as measured with the Maslach Burnout Inventory - General Survey (MBI-GS), a three-dimensional construct and how invariant is the factorial structure across occupations (Finnish) and national samples (Finnish, Swedish and Dutch)? How persistent is exhaustion over time? 2) What is the sequential process of burnout? Is it similar across occupations? How do work stressors relate to the process? 3) How does burnout relate to severe health consequences as well as temporary and chronic work disability according to hospitalization periods, sick-leave episodes and receiving disability pensions? The data were collected between 1986 and 2005. The population of the study consisted of respondents to a company-wide questionnaire survey carried out in 1996-1997 (N=9705, response rate 63%). The participants comprised 6025 blue-collar workers and 3680 white-collar workers. The majority were men (N=7494) and the average age was 43.7 years. In addition, a sample from the population had responded to a questionnaire survey in 1988, which was combined with the 1996 data to form panel data on 713 respondents. The register-based data were collected between 1986 and 2005 from 1) the company's occupational health services' records for a sample of respondents from the 1996 questionnaire survey (sick-leave data), 2) hospitalization records from the Hospital discharge register, and 3) disability pension records from the Finnish Centre for Pensions. These data were combined person by person with the 1996 questionnaire survey data with the help of personal identification numbers which were saved with the study numbers by the researchers. The results showed that burnout consists of three separate but correlating symptoms: exhaustion, cynicism and lack of professional efficacy. As a syndrome, burnout was strongly related to job stressors at work, and seemed to develop from exhaustion through cynicism to lack of professional efficacy in a similar manner among white-collar and blue-collar employees. The results also showed that exhaustion persisted even after eight years of follow-up but did not predict cynicism or lack of professional efficacy after that amount of time. Nor were job stressors longitudinally related to burnout. Longitudinal results were obtained for the severe health-related consequences of burnout. The investigated outcomes represented different phases of health deterioration ranging from sick-leaves and hospitalization periods to receiving work disability pensions. The results showed that burnout syndrome, and its elements of exhaustion and cynicism, were related to future mental and cardiovascular disorders as indicated by hospitalization periods. Burnout was also related to future sick-leave periods due to mental, cardiovascular and musculoskeletal disorders. Of the separate elements, exhaustion was related to the same three categories of disorder, cynicism to mental, musculoskeletal and digestive disorders, and lack of professional efficacy to mental and musculoskeletal disorders. Burnout also predicted receiving disability pensions due to mental and musculoskeletal disorders among initially healthy subjects. Exhaustion was related to receiving disability pensions even when self-reported chronic illness was taken into account. The results suggest that burnout is a multidimensional, chronic, work-related syndrome, which may have serious consequences for health and work ability.

The Quest for Well-being in Growth Industries 2: The Survey

This working paper reports the ongoing research conducted in the research project, The Quest for Well-being in Growth Industries: A Collaborative Study in Finland and Scotland, under the auspices of Academy of Finland research programme, The Future of Work and Well-being. The research project examines the contradictory pressures for policies and practices towards both the inhibition and the enhancement of work-related well-being that are likely in growth industries. The overall aim is to evaluate the development, implementation and use of work-related well-being policies in four selected growth industries. These – electronics, care, finance and accounting, and tourism – have been selected on the basis of EU and national forecasts, and demographic and socio-economic trends in standard and non-standard employment. In this paper we aim to review the survey that constitutes the second main phase of this research.

Processing of Ultrasonic Signal for Transducer Characterization and for Improving Signal-To-Noise Ratio

This paper describes the work related to characterisation of an ultrasonic transducer fabricated in the laboratory. The response of the medium to the ultrasonic wave was obtained by converting the time domain signal to frequency domain, using the FFT algorithm. Cross-correlation technique was adopted to increase the S/N ratio in the raw time domain signal and subsequently, to determine the ultrasonic velocity in the medium.

Probing Single and Bilayer Graphene Field Effect Transistors By Raman Spectroscopy

This article is a review of our work related to Raman studies of single layer and bilayer graphenes as a function Fermi level shift achieved by electrochemically top gating a field effect transistor. Combining the transport and in situ Raman studies of the field effect devices, a quantitative understanding is obtained of the phonon renormalization due to doping of graphene. Results are discussed in the light of time dependent perturbation theory, with electron phonon coupling parameter as an input from the density functional theory. It is seen that phonons near and Gamma and K points of the Brillouin zone are renormalized very differently by doping. Further, Gamma-phonon renormalization is different in bilayer graphene as compared to single layer, originating from their different electronic band structures near the zone boundary K-point. Thus Raman spectroscopy is not only a powerful probe to characterize the number of layers and their quality in a graphene sample, but also to quantitatively evaluate electron phonon coupling required to understand the performance of graphene devices.

From lakes to lungs : assessing microbial activity in diverse environments

All major geochemical cycles on the Earth’s surface are mediated by microorganisms. Our understanding of how these microbes have interacted with their environments (and vice versa) throughout Earth's history, and how they will respond to changes in the future, is primarily based on studying their activity in different environments today. The overarching questions that motivate the research presented in the two parts of this thesis -- how do microorganisms shape their environment (and vice versa)? and how can we best study microbial activity in situ? -- have arisen from the ultimate goal of being able to predict microbial activity in response to changes within their environments both past and future.

Part one focuses on work related to microbial processes in iron-rich Lake Matano and, more broadly, microbial interactions with the biogeochemical cycling of iron. Primarily, we find that the chelation of ferrous iron by organic ligands can affect the role of iron in anoxic environmental systems, enabling photomixotrophic growth of anoxygenic microorganisms with ferrous iron, as well as catalyzing the oxidation of ferrous iron by denitrification intermediates. These results imply that the ability to grow photomixotrophically on ferrous iron might be more widespread than previously assumed, and that the co-occurrence of chemical and biological processes involved in the coupled biogeochemical cycling of iron and nitrogen likely dominate organic-rich environmental systems.

Part two switches focus to in situ measurements of growth activity and comprises work related to microbial processes in the Cystic Fibrosis lung, and more broadly, the physiology of slow growth. We introduce stable isotope labeling of microbial membrane fatty acids and whole cells with heavy water as a new technique to measure microbial activity in a wide range of environments, demonstrate its application in continuous culture in the laboratory at the population and single cell level, and apply the tool to measure the in situ activity of the opportunistic pathogen Staphylococcus aureus within the environment of expectorated mucus from cystic fibrosis patients. We find that the average in situ growth rates of S. aureus fall into a range of generation times between ~12 hours and ~4 days, with substantial heterogeneity at the single-cell level. These data illustrate the use of heavy water as a universal environmental tracer for microbial activity, and highlight the crucial importance of studying the physiology of slow growth in representative laboratory systems in order to understand the role of these microorganisms in their native environments.

Avaliação das condições ambientais e de trabalho em salas cirúrgicas e de necropsia - estudos de casos em hospitais públicos e IMLs da região metropolitana do Rio de Janeiro

A qualidade do ar é um importante indicador de saúde ambiental, sendo o seu monitoramento contínuo necessário. Apesar da relevância do tema, há muitos países em que os limites de exposição para agentes biológicos ainda não foram estabelecidos ou foram definidos de forma inadequada, podendo comprometer a qualidade ambiental. Os ambientes hospitalares, assim como as salas de necropsia podem apresentar problemas de contaminação do ar por agentes microbiológicos, necessitando de monitoramento contínuo a fim de evitar a ocorrência de doenças nos trabalhadores e na população em geral. Este estudo realizou a avaliação microbiológica do ar em hospitais públicos e IMLs da região metropolitana do Rio de Janeiro em salas cirúrgicas e de necropsia. A pesquisa exploratória e descritiva baseou-se em levantamento bibliográfico e investigação de campo, através de estudos de casos. Os dados foram obtidos por meio de entrevistas e observação direta nos locais de trabalho, onde foram realizadas as avaliações microbiológicas do ar. As variações em salas cirúrgicas para bactérias e fungos foram respectivamente de 14,99 ufc/m3 88,29 ufc/m3 e de 45,93 ufc/m3 - 742,09 ufc/m3. Já nas salas de necropsia os valores para bactérias e fungos variaram respectivamente de 18,96 ufc/m3 54,9 ufc/m3 e de 144,87 ufc/m3 - 1152,01 ufc/m3. Foram identificados tanto no ambiente cirúrgico como nas salas de necropsia a presença dos seguintes fungos: Aspergillus sp., Neurospora sp., Penicillium sp., Fusarium sp., Cladosporium sp., Curvularia sp., e Trichoderma sp. Já em relação às bactérias foram identificadas as presenças de Staphilococcus sp., Streptococcus sp. e Micrococcus sp. Foram traçadas recomendações para melhoria da qualidade ambiental e do ar. Os resultados indicaram que os valores são elevados quando comparados com as recomendações das normas internacionais. Foram encontrados valores inferiores aos sugeridos pela CP n. 109 da ANVISA. A presença de microrganismos patogênicos sugere adoção de medidas de controle ambiental. O estudo apontou a necessidade urgente do estabelecimento de valores de referência para ambientes hospitalares no Brasil a fim de garantir condições seguras que não venham a comprometer a saúde dos pacientes e profissionais de saúde envolvidos.

Chuva de sementes: dinâmica de dispersão na presença de uma espécie exótica invasora, Artocarpus heterophyllus Lam. (jaqueira), no Parque Estadual da Ilha Grande, Angra dos Reis, RJ

A chuva de sementes é a dinâmica de dispersão de uma floresta, representando o que chega ao solo por meio dos agentes dispersores. Na comunidade de plantas, as síndromes de dispersão predominantes permitem entender os estádios sucessionais, estrutura e o nível de conservação da vegetação. No Brasil, a jaqueira, Artocarpus heterophyllus, é considerada uma espécie exótica invasora, que foi introduzida no período colonial. Essa invasão biológica pode comprometer a dispersão dos diásporos de espécies nativas pela chuva de sementes, já que a dispersão é influenciada pela distribuição espacial das plantas e pelas barreiras presentes no ambiente. O trabalho teve por objetivo verificar se a jaqueira, por ser uma espécie exótica invasora, influência na composição e abundância da chuva de sementes. O estudo foi realizado em floresta Atlântica, localizada no Parque Estadual da Ilha Grande, RJ. Foram utilizados para a coleta da chuva de semente 16 coletores de 1m de diâmetro, em áreas com (C) e sem (S) jaqueira, totalizando 32 coletores verificados mensalmente durante um ano de coleta. As análises estatísticas realizadas foram ANOVA, Regressão e NMDS, com o objetivo de verificar se a presença da jaqueira estaria influenciando na chuva de sementes quanto a riqueza, composição e abundância. Foram coletadas 320 amostras e contabilizadas 166.376 sementes, sendo encontrados 84 morfoespécies, 29 espécies em 25 famílias e 55 morfoespécies não identificadas. As áreas sem (S) jaqueira apresentaram maior riqueza, menor abundância e maior diversidade. Nas áreas com jaqueira (C) a abundância de sementes nativas apresentou uma relação negativa com a abundância dessa exótica nas parcelas. A composição e a abundância dos diásporos não tiveram uma separação nítida entre as áreas com e sem jaqueiras, como mostrado no NMDS. Porém, quando analisado o primeiro eixo do NMDS com a abundância de jaqueiras, a ordenação das grades mostrou ter uma relação com a abundância de jaqueiras. As principais síndromes de dispersão observadas no trabalho, referente às espécies que foram identificadas, foram à anemocoria e a zoocoria, sendo esta ultima síndrome a mais abundante entre as áreas. Os resultados mostraram que a presença das jaqueiras afeta, negativamente a chuva de sementes no Parque Estadual da Ilha Grande. Uma menor riqueza e abundância de sementes nativas alcançaram o solo nas áreas com jaqueira (C) podendo afetar a sucessão e a dinâmica da floresta.

As tramas sociais do trabalho ambulante e a experiência de trabalhadores em Rio das Ostras/RJ

A presente dissertação se insere no campo de estudo sobre o trabalho informal, tendo como universo empírico de investigação a experiência de trabalho dos trabalhadores ambulantes integrantes do Programa Renda Alternativa, em Rio das Ostras/RJ. Portanto, a pesquisa foi desdobrada em três dimensões: 1) levantamento e estudo bibliográfico; 2) levantamento de dados sobre a formação sócio-histórica da cidade de Rio das Ostras; e, 3) trabalho de campo com ambulantes. Por meio desses dispositivos, a pesquisa buscou compreender os laços entre informalidade do trabalho e dinâmica capitalista, por meio da tradição de estudos das Ciências Sociais nessa área. Seguidamente, a pesquisa se ocupou do estudo de outras investigações sobre trabalho ambulante visando conhecer e ampliar o escopo de análise das peculiaridades desse tipo de trabalho no contexto de reprodução social da chamada superpopulação relativa. Esse universo de questões teóricas, analíticas e empíricas foi confrontado com as especificidades do contexto socioeconômico da cidade de Rio das Ostras, recentemente recomposta como um dos elos da cadeia produtiva do petróleo. Outro eixo da investigação de campo foi conhecer o trabalho, o que foi realizado por meio de entrevistas semi-estruturadas com os trabalhadores ambulantes do município, buscando perceber a relação do trabalhador com o trabalho ao longo de sua vida, as marcas das conjunturas socioeconômicas nas trajetórias e o papel da família e do associativismo na ocupação ambulante. Os achados da pesquisa mostram que o trabalho ambulante acomete gerações de trabalhadores como consequência do desenvolvimento desigual e dependente do capitalismo que limita a oferta de emprego. Somado a isso temos os processos de transformações socioeconômicas das últimas décadas que intensificam as formas de precarização do trabalho potencializando a chamada informalidade do trabalho. Esse processo se intensifica na região em estudo através dos impactos trazidos pelo intenso incremento das indústrias de petróleo e gás que não absorvem a força de trabalho disponível no local e atraída, engendrando uma densa superpopulação relativa para o capital, no município. A experiência de trabalho dos ambulantes que participaram da pesquisa mostra que a mesma é entrecortada por formas laborativas variadas, baixa qualificação profissional, além de dependência dos familiares, de ações públicas do Estado e do associativismo. A expropriação do direito ao emprego empurra os trabalhadores para experiências laborativas inseguras, incertas e sem proteção social. A repetição dessa história entre familiares amplia a percepção da perenidade da expropriação social entre gerações de trabalhadores.

Exploring the relationship between impulsivity and decision-making on mobile devices.

Mobile devices offer a common platform for both leisure and work-related tasks but this has resulted in a blurred boundary between home and work. In this paper we explore the security implications of this blurred boundary, both for the worker and the employer. Mobile workers may not always make optimum security-related choices when ‘on the go’ and more impulsive individuals may be particularly affected as they are considered more vulnerable to distraction. In this study we used a task scenario, in which 104 users were asked to choose a wireless network when responding to work demands while out of the office. Eye-tracking data was obtained from a subsample of 40 of these participants in order to explore the effects of impulsivity on attention. Our results suggest that impulsive people are more frequent users of public devices and networks in their day-to-day interactions and are more likely to access their social networks on a regular basis. However they are also likely to make risky decisions when working on-the-go, processing fewer features before making those decisions. These results suggest that those with high impulsivity may make more use of the mobile Internet options for both work and private purposes but they also show attentional behavior patterns that suggest they make less considered security-sensitive decisions. The findings are discussed in terms of designs that might support enhanced deliberation, both in the moment and also in relation to longer term behaviors that would contribute to a better work-life balance.

Psychological processes underlying nurses' handwashing behaviour

Aim/Background Psychological models of behaviour change have been found to be useful in predicting health-related behaviour in patients but have rarely been used in relation to the health behaviour of staff. This study explored the association between a range of psychological variables and self-reported handwashing in a sample of nurses who work in a large general hospital. Method A questionnaire-based cross-sectional, correlational study was used. Questionnaires examining demographics, self-efficacy, perceived importance of handwashing, perception of risk, occupational stress and training related to handwashing were administered to an opportunity sample (n = 76) of nurses drawn from an acute hospital. ANOVAs, correlation and regression analyses were performed to determine significant covariates of handwashing behaviour. Findings There was a weak relationship between demographic variables and self-reported handwashing. The degree to which employees perceived their workplace to assist handwashing and perceived importance of handwashing were related to self-reported handwashing. Accordingly further covariates of these variables were sought. Training received and occupational stress both covaried with nurses’ perceptions of the degree to which their workplace assisted handwashing. Nurses’ beliefs regarding the transmission of infections covaried with perceived importance of handwashing. Conclusion Occupational stress was observed to reduce the perception of having a supportive employer: organisations need to facilitate handwashing and protect staff from factors that have a detrimental impact, such as work-related stress. Nurses’ perceived importance of the potential for poor handwashing practice to contribute to the transmission of infections should be highlighted in interventions.

Melt-compounded nanocomposites of titanium dioxide atomic-layer-deposition-coated polyamide and polystyrene powders

Polyamide and polystyrene particles were coated with titanium dioxide films by atomic layer deposition (ALD) and then melt-compounded to form polymer nanocomposites. The rheological properties of the ALD-created nanocomposite materials were characterized with a melt flow indexer, a melt flow spiral mould, and a rotational rheometer. The results suggest that the melt flow properties of polyamide nanocomposites were markedly better than those of pure polyamide and polystyrene nanocomposites. Such behavior was shown to originate in an uncontrollable decrease in the polyamide molecular weight, likely affected by a high thin-film impurity content, as shown in gel permeation chromatography (GPC) and scanning electron microscope (SEM) equipped with an energy-dispersive spectrometer. Transmission electron microscope image showed that a thin film grew on both studied polymer particles, and that subsequent melt-compounding was successful, producing well dispersed ribbon-like titanium dioxide with the titanium dioxide filler content ranging from 0.06 to 1.12wt%. Even though we used nanofillers with a high aspect ratio, they had only a minor effect on the tensile and flexural properties of the polystyrene nanocomposites. The mechanical behavior of polyamide nanocomposites was more complex because of the molecular weight degradation. Our approach here to form polymeric nanocomposites is one way to tailor ceramic nanofillers and form homogenous polymer nanocomposites with minimal work-related risks in handling powder form nanofillers. However, further research is needed to gauge the commercial potential of ALD-created nanocomposite materials. Copyright (C) 2011 John Wiley & Sons, Ltd.

Spatial Mobility Intentions, the Labour Market and Incapacity Benefit Claimants Evidence from Northern Ireland

The paper analyses the work-related spatial mobility intentions of incapacity benefit (IB) claimants in Northern Ireland using a new survey dataset. Greater understanding of the prospective mobility of benefit claimants contributes to debates about employability, inclusion in the labour market and arguments about spatial mismatch. The analysis finds that IB claimants are not markedly less mobile than other population groups; that mobility is shaped by age, level of qualification, illness type, ability to drive and motivation; and that geography is important in several ways. The paper concludes by arguing that limited spatial mobility is a good indicator of disadvantage and that spatial mobility should be placed nearer the centre of the design and delivery of labour market policy
