Vocational rehabilitation improves cognition and negative symptoms in schizophrenia

Several studies in schizophrenia found a positive association between cognitive performance and work status, and it has been reported that good cognitive performance at the outset does predict the success of vocational interventions. However little has been done to investigate whether vocational interventions itself benefit cognitive performance. To test this hypothesis we performed a randomized, placebo-controlled trial to investigate in remitted schizophrenic patients the effect of a 6-months vocational rehabilitation program on cognitive performance. We recruited 112 remitted and clinically stable schizophrenic patients who aimed to enter a vocational rehabilitation program. From these, 57 immediately entered a 6-months vocational rehabilitation program, whereas the remaining 55 were allocated to a waiting-list; the latter formed our control group, which received during the 6 months out-clinic follow-up treatment. Before and after the 6-months period we assessed changes in cognitive performance through a neuropsychological test battery, as well as changes in the psychopathological status and in quality of life. We found that vocational rehabilitation significantly improved patients` performance in cognitive measures that assess executive functions (concept formation, shifting ability, flexibility, inhibitory control, and judgment and critics abilities). Moreover, after 6 months the vocational group improved significantly in the negative symptoms and in quality of life, as compared to controls. Together with results from the literature, our findings reinforce the notion that the inclusion of vocational interventions may enhance the effectiveness of therapeutic strategies for schizophrenia patients.

The Association Between Physical Activity, Productivity, and Health Care Utilization Among Employees in Brazil

Objective: To document the relationship between physical activity, absenteeism, presenteeism, health care utilization, and morbidity among Brazilian automotive workers. Methods: Eligible employees (N = 620) completed a questionnaire. Univariate correlations, multivariate logistic regression, and Pearson`s product-moment correlation coefficient were used. Results: Work absenteeism was associated with physical activity at work (OPA) (odds ratio, [OR] = 1.63, 95% confidence interval [CI] = 1.31 to 2.02) and leisure physical activity time excluding sport (OR = 0.73, 95% CI = 0.58 to 1.00). Health care utilization was associated with OPA (OR = 1.25, 95% CI = 0.99 to 1.58) and leisure physical activity time excluding sport (OR = 0.76, 95% CI = 0.57 to 1.02). Presenteeism showed an indirect relationship with OPA (r = 0.099, P = 0.014). Referred morbidity was associated with OPA (OR = 1.3, 95% CI = 1.06 to 1.61) and sports during leisure time (OR = 0.67, 95% CI = 0.54 to 0.82). Conclusions: Physical activity components seem to have differential relationships to the studied outcomes. Associations measured indicate negative impacts of OPA on absenteeism, health care utilization, and morbidity, although overall physical activity did not show these relationships.

Aggregated personality, climate and demographic factors as predictors of departmental shrinkage

The present study investigated how demographic, personality, and climate variables act to predict departmental theft. Participants in the current field survey were 153 employees from 17 departments across two stores. The results of confirmatory factor analyses supported the construct validity of the Big Five Inventory (John, Donahue, & Kentle, 1991) and the Occupational Climate Questionnaire (Furnham & Gunter, 1997) in UK work settings. The results of regression analysis indicate that the variability in departmental theft is accountable in terms of a linear combination of demographic, personality, and climate factors. We concluded that an expanded theoretical perspective (utilizing demographic, personality, and climate variables) explained more variance than might otherwise be expected from any single perspective. Indeed, climate, personality, and demographic variables operated legitimately at the departmental level. Finally, we explained aggregated personality as a form of social interaction which is the by-product of individual differences.

Motivação dos trabalhadores na sociedade do conhecimento

RESUMO: Nas sociedades avançadas da actualidade, aqui denominadas por sociedades do conhecimento, os níveis de responsabilidade e de exigência mental das organizações para com os seus trabalhadores é superior a qualquer outra realidade anterior. É emergente a necessidade de redefinir a estrutura das organizações, para que os reponsáveis e os seus respectivos colaboradores usufruam de condições potenciadoras do seu desempenho profissional. Os perfis ideais dos responsáveis de equipas e , em especial, dos «novos» trabalhadores produtores de conhecimento, incorporam determinadas características fundamentais para favorecerem o processo criativo e o trabalho autónomo. Mas as alterações não estão confinadas à dimensão laboral, pois surgiram igualmente mudanças profundas no seio da sociedade, as quais obrigam à existência de uma nova relação entre a vida pessoal e a vida profissional dos cidadãos. Todas estas transformações resultam na necessidade de uma componente motivacional muito forte por parte dos trabalhadores, os quais dependem apenas de si mesmos para a conseguir obter e manter. A solução desta problemática surge aqui configurada sob a forma de uma mudança de atitude por parte de todos os trabalhadores, a qual deverá fomentar a ocorrência de «Experiências óptimas» provenientes do desenvolvimento da actividade profissional dos mesmos, tal como é sugerido pela Teoria do Fluxo. Esta versão profunda da motivação intrínseca e estável é proposta como modelar e mesmo fulcral para o trabalhador na Sociedade do conhecimento. ABSTRACT: In today’s advanced societies, here referred as Knowledge Societies, the levels of responsibility and mental demanding which organizations require from their workers is higher than ever before. The need to redefine organizations structures is now emerging in order to allow CEO’s and their co-workers having access to encouraging conditions which improve their work performance. The ideal profile for a team leader and especially for the «new» Knowledge production workers, incorporate a defined group of fundamental characteristics to encourage the creative process and the autonomous work. But changes are not confined to the labor dimension. The Society core also suffered profound changes which demand the existence of a new relation between personal and professional life of its citizens. All these changes create the need for the existence of high motivational levels inside all workers, which now have to find their own ways to get and maintain it. The solution for this problem is presented here as a switch in workers attitude, which will increase the occurrence of optimal experiences coming directly from the development of their professional activity like it’s suggested in the flow theory. This version of the deep intrinsic and stable motivation is proposed as a model or even a central solution to the worker in the Knowledge Society.

Enterprise Social Networking

Microblogging in the workplace as a functionality of Enterprise Social Networking (ESN) platforms is a relatively new phenomenon of which the use in knowledge work has not yet received much attention from research. In this cross-sectional study, I attempt to shed light on the role of microblogging in knowledge work. I identify microblogging use practices of knowledge workers on ESN platforms, and I identify its role in supporting knowledge work performance. A questionnaire is carried out among a non-representative sample of knowledge workers. The results shed light on the purposes of the microblogging messages that knowledge workers write. It also helps us find out whether microblogging supports them in performing their work. The survey is based on existing theory that supplied me with possible microblog purposes as well as theory on what the actions of knowledge workers are. The results reveal that “knowledge & news sharing”, “crowd sourcing”, “socializing & networking” and “discussion & opinion” are frequent microblog purposes. The study furthermore shows that microblogging benefits knowledge workers’ work. Microblogging seems to be a worthy addition to the existing means of communication in the workplace, and is especially useful to let knowledge, news and social contact reach a further and broader audience than it would in a situation without this social networking service.

A videovigilância no local de trabalho

The emergence of new technologies has introduced significant changes in the citizens life’s. There is a constant evolution of technological means and profound impact of their use in the habits of life of the human being. These new technological media are important tools in labor relations. The working and businesses worlds are increasingly turning to these new technologies, so that the use of video surveillance in the workplace is nowadays common. New technologies in general and the use of video surveillance in workplace in particular are providing ways to allow control of the work performance that are desired by most employers. However, the collection of images in the workplace often collides with the fundamental rights and freedoms of workers, in particular, with the right to privacy. The subject concerns the question of investigating is whether the images collected in workplace can be used as evidence in disciplinary proceedings. In fact, this issue is controversial. Doctrine and jurisprudence defend, at least, two responses for the same question. Those who understand that the evidence may be admitted for not violate any right of the worker, and others who argue that the evidence should not be admitted in disciplinary office. In the Portuguese legal system, there is, even, a new intermediate theory that begins to be defended, that only on certain occasions the evidence may be admitted. The solution to this problem involves the study of employment law and data video surveillance processing. Analysis of workers fundamental rights is fundamental to come to a grounded conclusion.

Study of the muscular activation in obese and non-obese subjects during lifting loads

The obesity prevalence is increasing among the workforce of the developed countries. However, obesity seems to negatively affect the individuals’ work performance. In occupational contexts, manual lifting tasks are frequent and can produce significant muscle loading. With the aim of analysing the possible effect of obesity on workers’ muscular activation, surface electromyography data were collected from six muscles recruited during these tasks. In the current study, 6 different tasks of manual lifting (3 loads × 2 lifting styles) were performed by 14 participants with different obesity levels. Electromyography data normalization was based on the percentage of maximum contraction during each task. The muscles’ activation times before each task were also calculated. The current study suggests that obesity can increase the maximum contraction during each task and the delays on muscles’ activation time. This study suggests that obese individuals can present some changes on their muscle activation during lifting, when comparing with non-obese individuals, and reinforces the need to develop further studies focused on obesity as a risk factor for musculoskeletal disorders development.

Motivating techniques within Irish and American manufacturing and service companies in the Northwest of Ireland

In today’s world, many companies are concentrating on both their technology and human resources to provide them with their competitive advantage. Hence, understanding what motivates people is particularly important for managers in order to develop and sustain a competitive edge. As a result, numerous theories have been advanced to help our understanding of the subject matter and from these theories many motivational methods have evolved to enhance motivation within the workplace. In addition, research has been conducted on the various types of motivational techniques utilised by companies within Ireland. However, very little research has been completed within specific geographical regions in Ireland concerning the types of motivational techniques implemented at different job levels and their impact on employees work performance. Thus the objective of this research was to identify the motivational techniques utilised at different job levels within large manufacturing and service companies in the Northwest of Ireland and examine how these techniques influence the performance levels of employees. Furthermore, the study examined if these companies have changed from traditional ways of motivating employees to newer techniques. The research methodologies used to undertake the research included interviews with the HR managers and questionnaires completed by different employees at various job levels within the participating companies. Overall the conclusions were varied. Many different types of motivation techniques were found within the study’s participating companies. Irish companies are improving their motivational techniques, however most of these techniques are only used within higher job levels. In contrast to their American counterparts, a variety of motivational techniques are utilised and implemented at all job levels. On a more positive note, the majority of these motivational techniques do increase performance levels at all job levels. From the extensive primary and secondary research conducted, the thesis concludes by offering a number of recommendations to assist companies in further development of their motivational techniques for all job levels. These recommendations hope to augment the success of companies through an enhanced motivated workforce.

An easy functional capacity evaluation in chronic low back pain

Lifting is said to be on of the major risk factors for the onset of low back pain, several different measures has been developed to study this. Several programs are available in order to measure these components, or to determine the ability of an individual to perform a certain job or to discover if the job creates dangerous positions for the worker. In these different fields reliable and valid instruments exist but they are costly and time spending. We present a simplified functional capacity measuring that we use daily in practise. Method: 280 patients have been evaluated on this base. The majority was referred to multidisciplinary rehabilitation treatment. The patients had recurrent back problems for months or years. Inclusion criteria were between 18 and 64 years, currently of work, no work compensation. Exclusion criteria were chronic low back pain with a specific cause. They followed a one-hour evaluation test as a functional capacity evaluation at the end of the multidisciplinary treatment period, it was compared to the PILE-test done at the beginning and at the end. Results: We included 280 subjects: 160 men and 120 women. Mean age 43.6 by the women and 44 years by the men. We studied the caring foot-hip, hip-shoulder, 5 m carrying, pushing and tiring and the global weight carried during the test. We found this global value to be 696 kg by men and 422 kg by women suffering from chronic lumbar pain. The increase in this value had a clear incidence on a greater work ability, as had a decrease. Conclusions: We were able to develop a lifting capacity program that is easy to reproduce and not expensive, giving us the possibility to have an idea on how to reorient the patients according to their work place and their capacities. We could also have an information of work performance and power consumption. It should be more tested and compared to standard capacity in the healthy population.

Depression and suicide risk among nursing professionals: an integrative review

Abstract OBJECTIVE Discussing the factors associated with major depression and suicide risk among nursing professionals. METHOD An integrative review in PubMed/MEDLINE, LILACS, SciELO and BDENF databases, between 2003 and 2015. RESULTS 20 published articles were selected, mostly from between 2012 and 2014, with significant production in Brazil. Nursing professionals are vulnerable to depression when young, married, performing night work and having several jobs, and when they have a high level of education, low family income, work overload, high stress, insufficient autonomy and a sense of professional insecurity and conflict in the family and workrelationship. Suicide risk was correlated with the presence of symptoms of depression, high levels of emotional exhaustion, depersonalization and low personal accomplishment; characteristics of Burnout Syndrome. CONCLUSION Suicide risk among nursing professionals is associated with symptoms of depression and correlated with Burnout Syndrome, which can affect work performance.

Ikääntyvien työkyky ja työkykyä ylläpitävä toiminta, case Stora Enson Anjalankosken tehtaat

Työkyky koostuu psyykkisestä, sosiaalisesta ja fyysisestä osa-alueesta. Psyykkinen osa-alue koostuu jaksamisesta, sitoutumisesta, vuorovaikutuksesta sekä osaamisesta eli siis lähinnä yksilön ominaisuuksista, kun taas sosiaaliseen työkykyyn vaikuttavat myös työyhteisön jäsenet, työympäristö sekä organisaatiokulttuuri. Fyysinen työkyky koostuu pääosin niistä fyysisen toimintakyvyn ominaisuuksista, joita työn suorittamisessa tarvitaan. Toimintakyky määrittää myös sosiaalista ja psyykkistä työkykyä, siltä osin kun sitä tarvitaan työstä selviytymisessä. Ikääntyminen asettaa haasteita mutta myös mahdollisuuksia työkyvylle. Selkeintä heikkeneminen on fyysisellä osa-alueella, kun taas sosiaalisen ja psyykkisen osa-alueen heikkeneminen ei yleensä näy työiässä. Päinvastoin, ikääntymisen on todettu parantavan esim. sosiaalisia taitoja ja lisäävän arkipäivän viisautta.Työkykytoiminnalla pyritään ylläpitämään työkykyä tai ehkäisemään tai korjaamaan työkyvyn alenemaa. Se voi kohdistua yksilöön, työyhteisöön tai koko organisaatioon. Toiminnan onnistuminen edellyttää kaikkien organisaation tai työyhteisön jäsenten osallistumista ja sitoutumista toimintaan, ja onnistuneen työkykytoiminnan seurauksena hyötyvät työntekijän ja yrityksen lisäksi yhteiskunta. Työkykytoiminnan keinoja ovat työn, yksilön, esimiestyön sekä työyhteisön kehittäminen.Stora Enson Anjalankosken tehtailla toteutettiin kolmevuotinen ikääntyvien työkykyprojekti, jonka tavoitteena oli työ- ja toimintakykyä parantamalla ehkäistä ennenaikaista eläköitymistä ja säilyttää ikääntyvien hiljainen tieto mahdollisimman pitkään yrityksessä. Projektin jäsenien työkyky oli jo varsin korkea jo projektin alussa, mutta se onnistuttiin pitämään ikääntymisestä huolimatta korkealla tasolla projektin aikana. Projektin jäseniin kohdistuneen tutkimuksen perusteella tärkeimmäksi työkyvyn määrittäjäksi nousivat työtehtävät tai paremminkin niiden soveltuminen yksilön tarpeisiin, kykyihin ja arvostuksiin.

Ammatti-identiteetin rakentuminen sairaanhoitajilla

Ammatti-identiteetti luo pohjan henkilön ammattitaidolle, oman, henkilökohtaisen ammatillisen osaamisen arvostamiselle sekä koko ammattikuvalle, sille millaisena työntekijänä jokainen itsensä näkee. Vahva ammatti-identiteetti aikaansaa positiivisen takaisinkytkennän, kun hyvin tehdyn työn seurauksena saadaan kannustavaa palautetta, mikä kasvattaa itsetuntoa, joka puolestaan luo positiivinen omakuvan, jonka seurauksena syntyy vahva ammatti-identiteetti. Tämän tutkimuksen tarkoituksena on selvittää millä tavoin ammatti-identiteetti rakentuu ja muotoutuu, ja millaisia ovat sitä muovaavat tekijät. Samalla pyritään selvittämään millainen merkitys ammatti-identiteetillä on työn suorittamiseen, työssä viihtymiseen sekä omaan näkemykseen itsestään tietyn alan ammattilaisena. Tutkimuksen kontekstina on terveydenhoitoala, ja empiriassa tutkitaan sairaanhoitajien ammatti-identiteettiä. Tutkimuksen perusteella näyttää siltä, että sairaanhoitajat arvostavat ammattiaan ja ammattitaitoaan huolimatta yhteiskunnallisesta aliarvostuksesta. Tämä tukee käsitystä sairaanhoitajien vahvasta ammatti-identiteetistä. Tutkimuksen tulokset osoittavat, että sairaanhoitajan ammatti-identiteetti on moniulotteinen ilmiö. Ammatti-identiteetti ei ole irrallinen henkilön persoonallisesta identiteetistä, vaan ne tukevat toinen toistaan.

Tietotyön avainhenkilöiden sitoutuminen - Case Kymenlaakson sairaanhoitopiirin lääkärit

Tutkielmassa tarkasteltiin affektiivista eli tunnepohjaista sitoutumista organisaatioon ja selvitettiin, mitkä ovat sitä lisääviä ei-taloudellisia motivointikeinoja. Tulokset osoittivat, että organisaatioon sitoutumista lisääviä ulottuvuuksia ovat itsensä kehittäminen, työtehtävien vaihto ja työn arvostus. Lisäksi selvitettiin affektiivisen sitoutumisen ja innovatiivisuuden välistä suhdetta ja niiden välillä todettiin merkittävä positiivinen yhteys. Tarkastelun kohteena olivat tietotyön avainhenkilöt, joiden sitoutuminen organisaatioon on merkityksellisintä sen toiminnan ja tuottavuuden kannalta. Ilmiötä tarkasteltiin ensisijaisesti tilastollisin menetelmin. Teoriaa testattiin empiirisesti Kymenlaakson sairaanhoitopiirin lääkäreihin, jotka edustavat erikoisosaamista julkisella sektorilla.

Hammaslääkärin ura. Odotukset ja kokemukset. [Career Expectations and Experiences of Dentists]

Tutkimuksella selvitettiin eri tekijöiden merkitystä hammaslääkärien tehdessä uraansa koskevia valintoja lähtien ammatinvalinnasta. Tutkimuksessa verrattiin erilaisissa työpaikoissa toimivien hammaslääkärien sekä hammaslääketieteen opiskelijoiden odotuksia ja kokemuksia. Tutkimus tehtiin kyselynä postitse lähetetyin lomakkein. Kyselyyn osallistui 350 hammaslääkäriä ja 115 opiskelijaa. Kiinnostus lääketieteeseen ja työn konkreettisuus olivat keskeisimmät syyt lähteä hammaslääketiedettä opiskelemaan. Suurin osa sekä hammaslääkäreistä että opiskelijoista valitsisi vähintään todennäköisesti saman ammatin uudelleen, hammaslääkäreistä yksityishammaslääkärit useimmin. 69 % hammaslääkäreistä oli aloittanut työuransa terveyskeskuksessa, opiskelijoista 46 % toivoi työpaikkaa yksityissektorilta ja 37 % terveyskeskuksesta. Hammaslääkärit kokivat työn mielekkyyden, positiivisen kaiun, työn ja elämän reunaehtojen sekä taloudellisen turvallisuuden vaikuttaneen ensimmäiseen työpaikkaan menoon vähemmän kuin opiskelijat arvioivat niiden vaikuttavan. Työssä tärkeänä sekä hammaslääkärit että opiskelijat pitivät hyviä työolosuhteita ja mielekästä työn sisältöä. Toimiva yhteistyö työparin kanssa oli myös erittäin tärkeää. Hammaslääkärit pitivät hyviä työoloja ja autonomiaa tärkeämpinä kuin opiskelijat, joille puolestaan uralla eteneminen ja työajan joustot olivat tärkeämpiä. Hammaslääkärit arvostivat työtä ja työssä suoriutumista sekä hyvää työpaikkaa enemmän kuin opiskelijat. Parhaiten työssään toteutuvana suhteessa asian merkitykseen hammaslääkärit kokivat autonomian ja huonoiten ilmapiirin. Naiset kokivat asioiden toteutumisessa enemmän puutteita kuin miehet. Työpaikkaansa heikosti sitoutuneita oli 8 %, joista valtaosa terveyskeskushammaslääkäreitä. Heikosti sitoutuneet kokivat sitoutuneita huonompina varsinkin työilmapiirin, työolosuhteet ja mahdollisuuden uralla etenemiseen. Hammaslääkärit olivat halukkaampia jatkokoulutukseen kuin kokivat siihen olevanmahdollisuuksia; 25 % oli harkinnut erikoistumista, mutta luopunut ajatuksesta, ja20 % halusi erikoistua, mutta koki siihen käytännön esteitä. Jatkossa tulisi tarkemmin analysoida ja toistettavin tutkimuksin seurata hammaslääkärien urakokemuksia ja valintoja sekä koetun työssä vallitsevan tilanteen ja asioiden merkityksen välistä suhdetta. Myös opiskelijoiden urasuunnitelmia ja arvostuksia tulisi tutkia säännöllisin väliajoin.
