Relationship Between Work Performance and Personality Traits in Hong Kong Organizational Settings

INTERNATIONAL JOURNAL OF SELECTION AND ASSESSMENT, Issue 1 2006
Graham P. Tyler
Four hundred and thirty-seven employees from four Hong Kong organizations completed the Traditional Chinese versions of the Fifteen Factor Personality Questionnaire Plus (15FQ+) and the Cross-Cultural Personality Assessment Inventory (CPAI-2) (indigenous scales) and provided objective and memory-based recent performance appraisal scores. A number of significant bivariate correlations were found between personality and performance scores. Hierarchical multiple regression analyses revealed that a number of the scales from the 15FQ+ contributed to significantly predicting four of the performance competency dimensions, but that the CPAI-2 indigenous scales contributed no incremental validity in performance prediction over and above the 15FQ+. Results are discussed in the light of previous research and a call made for continued research to further develop and increase the reliability of the Chinese instruments used in the study and to enable generalization of the findings with confidence.

Employer burden of mild, moderate, and severe major depressive disorder: mental health services utilization and costs, and work performance,

DEPRESSION AND ANXIETY, Issue 1 2010
Howard G. Birnbaum Ph.D.
Abstract Background: Treatment utilization/costs and work performance for persons with major depressive disorder (MDD) by severity of illness is not well documented. Methods: Using National Comorbidity Survey-Replication (2001,2002) data, US workforce respondents (n=4,465) were classified by clinical severity (not clinically depressed, mild, moderate, severe) using a standard self-rating scale [Quick Inventory of Depressive Symptomatology Self-Report (QIDS-SR)]. Outcomes included 12-month prevalence of medical services/medications use/costs and workplace performance. Treatment costs (employer's perspective) were estimated by weighing utilization measures by unit costs obtained for similar services used by MDD patients in claims data. Descriptive analysis across three severity groups generated ,2 results. Results: Using a sample of 539 US workforce respondents with MDD, 13.8% were classified mild, 38.5% moderate, and 47.7% severe cases. Mental health services usage, including antidepressants, increased significantly with severity, with average treatment costs substantially higher for severe than for mild cases both regarding mental health services ($697 vs. $388, ,2=4.4, P=.019) and antidepressants ($256 vs. $88, ,2=9.0, P=.001). Prevalence rates of unemployment/disability increased significantly (,2=11.7, P=.003) with MDD severity (15.7, 23.3, and 31.3% for mild, moderate, and severe cases). Severely and moderately depressed workers missed more work than nondepressed workers; the monthly salary-equivalent lost performance of $199 (severely depressed) and $188 (moderately depressed) was significantly higher than for nondepressed workers (,2=10.3, P<.001). Projected to the US workforce, monthly depression-related worker productivity losses had human capital costs of nearly $2 billion. Conclusions: MDD severity is significantly associated with increased treatment usage/costs, treatment adequacy, unemployment, and disability and with reduced work performance.

Severity of anxiety and work-related outcomes of patients with anxiety disorders

DEPRESSION AND ANXIETY, Issue 12 2009
Steven R. Erickson PharmD.
Abstract Background: This study examined associations between anxiety and work-related outcomes in an anxiety disorders clinic population, examining both pretreatment links and the impact of anxiety change over 12 weeks of treatment on work outcomes. Four validated instruments were used to also allow examination of their psychometric properties, with the goal of improving measurement of work-related quality of life in this population. Methods: Newly enrolled adult patients seeking treatment in a university-based anxiety clinic were administered four work performance measures: Work Limitations Questionnaire (WLQ), Work Productivity and Activity Impairment Questionnaire (WPAI), Endicott Work Productivity Scale (EWPS), and Functional Status Questionnaire Work Performance Scale (WPS). Anxiety severity was determined using the Beck Anxiety Inventory (BAI). The Clinical Global Impressions, Global Improvement Scale (CGI-I) was completed by patients to evaluate symptom change at a 12-week follow-up. Two severity groups (minimal/mild vs. moderate/severe, based on baseline BAI score) were compared to each other on work measures. Results: Eighty-one patients provided complete baseline data. Anxiety severity groups did not differ in job type, time on job, job satisfaction, or job choice. Patients with greater anxiety generally showed lower work performance on all instruments. Job advancement was impaired for the moderate/severe group. The multi-item performance scales demonstrated better validity and internal consistency. The WLQ and the WPAI detected change with symptom improvement. Conclusion: Level of work performance was generally associated with severity of anxiety. Of the instruments tested, the WLQ and the WPAI questionnaire demonstrated acceptable validity and internal reliability. Depression and Anxiety, 2009. © 2009 Wiley-Liss, Inc. [source]


Methamphetamine use among Australian workers and its implications for prevention

DRUG AND ALCOHOL REVIEW, Issue 3 2008
Professor ANN M. ROCHE Director
Abstract Introduction and Aims. Little attention has been directed to the use of methamphetamine among Australian workers. To address this, a study was conducted that examined drug consumption patterns of the Australian work-force. Design and Method. A secondary analysis of the 2004 National Drug Strategy Household Survey (NDSHS) data was undertaken that focused on methamphetamine use among those in paid employment. Results. Methamphetamine use in the past 12 months was reported by 4.0% of workers compared to 2.2% of respondents not in the paid work-force. A larger proportion of male (4.8%) than female workers (3.0%) used methamphetamine. The highest prevalence occurred among 18,29-year-old workers (11.2%; males: 12.6%; females: 9.4%), and among workers in hospitality (9.5%), construction (5.4%) and transport (5.4%) industries and among tradespeople (6.5%). Significantly more methamphetamine users reported absenteeism compared to users of other illicit drugs and non-drug users. Among respondents reporting methamphetamine use, 13.4% reported absenteeism due to illicit drug use, while 56.8% reported absenteeism due to any illness or injury. Significantly more methamphetamine users (32.9%) reported going to work under the influence than users of other illicit drugs. Compared to users of other illicit drugs, methamphetamine users were also significantly more likely to drive a car, operate heavy machinery or abuse someone while under the influence. Discussion and Conclusions. The specific details of the profile of workers using methamphetamine and the impact it has on work performance allows for the development of targeted interventions and tailored prevention strategies previously not possible.

Atorvastatin therapy improves exercise oxygen uptake kinetics in post-myocardial infarction patients

EUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 6 2007
M. Guazzi
Abstract Background Statins represent a modern mainstay of the drug treatment of coronary artery disease and acute coronary syndromes. Reduced aerobic work performance and slowed VO2 kinetics are established features of the clinical picture of post-myocardial infarction (MI) patients. We tested the hypothesis that statin therapy improves VO2 exercise performance in normocholesterolaemic post-MI patients. Materials and methods, According to a double-blinded, randomized, crossover and placebo-controlled study design, in 18 patients with uncomplicated recent (3 days) MI we investigated the effects of atorvastatin (20 mg day,1) on gas exchange kinetics by calculating VO2 effective time constant (tau) during a 50-watt constant workload exercise, brachial artery flow-mediated dilatation (FMD) as an index of endothelial function, left ventricular function (echocardiography) and C-reactive protein (CRP, as an index of inflammation). Atorvastatin or placebo was given for 3 months each. Results, Atorvastatin therapy significantly improved exercise VO2 tau and FMD, and reduced CRP levels. We did not observe changes in cardiac contractile function and relaxation properties during all study periods in either group. Conclusions, In post-MI patients exercise performance is a potential additional target of benefits related to statin therapy. Endothelial function improvement is very likely implicated in this newly described therapeutic property. [source]


SSRIs and cognitive performance in a working sample

HUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 8 2005
Emma J. K. Wadsworth
Abstract Background Studies of the impact of antidepressant use on cognitive performance have frequently been carried out among the elderly or on healthy volunteers. Comparatively little research has considered their impact on a relatively young, working population, particularly within the context of everyday life. Aims To examine any association between SSRI use and cognitive performance, mood and human error at work. Methods SSRI users and controls completed a battery of laboratory based computer tasks measuring mood and cognitive function pre- and post-work at the start and end of a working week. They also completed daily diaries reporting their work performance. Results SSRI use was associated with memory impairment: specifically poorer episodic, though not working or semantic memory. Effects of SSRI use on recognition memory seemed to vary according to the underlying psychopathology, while effects on delayed recall were most pronounced among those whose symptoms had not (yet) resolved. There were no detrimental effects on psychomotor speed, attention, mood or perceived human error at work. Conclusions The findings lend support to the SSRIs comparative safety, even among workers, particularly as the symptoms of the underlying psychopathology are successfully addressed. Possible memory impairments may, however, be found in those taking SSRIs. Copyright © 2005 John Wiley & Sons, Ltd. [source]


Effective work-life balance support for various household structures

HUMAN RESOURCE MANAGEMENT, Issue 2 2010
Lieke L. ten Brummelhuis
Abstract Today's workforce encompasses a wide variety of employees with specific needs and resources when it comes to balancing work and life roles. Our study explores whether various types of work-life balance support measures improve employee helping behavior and performance among single employees, employees with a partner, and employees with a partner and children. Using a sample of 482 employees at 24 organizations, the results showed that the organization's work-family culture improved work performance among parents but reduced performance among singles. Singles' work outcomes improved, however, when they had access to flexible work arrangements, whereas couples benefited from their supervisors' social support. The results stress the importance of the employee's household structure when considering appropriate support for balancing work and life roles. © 2010 Wiley Periodicals, Inc. [source]


Exploring alternative relationships between perceived investment in employee development, perceived supervisor support and employee outcomes

HUMAN RESOURCE MANAGEMENT JOURNAL, Issue 2 2010
Bård Kuvaas
The purpose of this study was to explore alternative relationships between perceived investment in employee development (PIED), perceived supervisor support (PSS), and employee outcomes in the form of attitudes (affective commitment and turnover intention) and work performance (work effort, work quality and organisational citizenship behaviour). A cross-sectional survey among 331 employees from a Norwegian telecommunications organisation showed that the relationship between PSS and employee attitudes was partially mediated by PIED. In addition, PSS was found to moderate the relationship between PIED and three self-report measures of work performance. The form of the moderation revealed a positive relationship only for high levels of PSS. These findings suggest that line managers are of vital importance in implementing developmental HR practices, either because they influence how such practices are perceived by employees, which, in turn, affects employee attitudes, or because positive experiences with both line managers and HR practices seem to be needed in order for developmental HR practices to positively influence employee performance.

The economic burden of depression and the cost-effectiveness of treatment

INTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 1 2003
Philip S. Wang
Abstract Cost-of-illness research has shown that depression is associated with an enormous economic burden, in the order of tens of billions of dollars each year in the US alone. The largest component of this economic burden derives from lost work productivity due to depression. A large body of literature indicates that the causes of the economic burden of depression, including impaired work performance, would respond both to improvement in depressive symptomatology and to standard treatments for depression. Despite this, the economic burden of depression persists, partly because of the widespread underuse and poor quality use of otherwise efficacious and tolerable depression treatments. Recent effectiveness studies conducted in primary care have shown that a variety of models, which enhance care of depression through aggressive outreach and improved quality of treatments, are highly effective in clinical terms and in some cases on work performance outcomes as well. Economic analyses accompanying these effectiveness studies have also shown that these quality improvement interventions are cost efficient. Unfortunately, widespread uptake of these enhanced treatment programmes for depression has not occurred in primary care due to barriers at the level of primary care physicians, healthcare systems, and purchasers of healthcare. Further research is needed to overcome these barriers to providing high-quality care for depression and to ultimately reduce the enormous adverse economic impact of depression disorders.

Personality and Performance at the Beginning of the New Millennium: What Do We Know and Where Do We Go Next?

INTERNATIONAL JOURNAL OF SELECTION AND ASSESSMENT, Issue 1-2 2001
Murray R. Barrick
As we begin the new millennium, it is an appropriate time to examine what we have learned about personality-performance relationships over the past century and to embark on new directions for research. In this study we quantitatively summarize the results of 15 prior meta-analytic studies that have investigated the relationship between the Five Factor Model (FFM) personality traits and job performance. Results support the previous findings that conscientiousness is a valid predictor across performance measures in all occupations studied. Emotional stability was also found to be a generalizable predictor when overall work performance was the criterion, but its relationship to specific performance criteria and occupations was less consistent than was conscientiousness. Though the other three Big Five traits (extraversion, openness and agreeableness) did not predict overall work performance, they did predict success in specific occupations or relate to specific criteria. The studies upon which these results are based comprise most of the research that has been conducted on this topic in the past century. Consequently, we call for a moratorium on meta-analytic studies of the type reviewed in our study and recommend that researchers embark on a new research agenda designed to further our understanding of personality-performance linkages.

Christian democracy, social democracy and the paradoxes of earnings-related social security

INTERNATIONAL JOURNAL OF SOCIAL WELFARE, Issue 1 2002
Johan Jeroen De Deken
This article compares the retirement policies of Belgium and Sweden in order to reveal the different incentive structures built into the pensions systems prevailing in countries that are taken to represent different approaches to welfare capitalism. It addresses the question of why in a Christian Democratic welfare state that is said to grant pensions rights on the basis of merit and past work performance one can find extremely low labour-force participation rates among elderly workers, while in a Social Democratic welfare state that is supposed to grant pension rights relatively independent of past labour-market performance, one can find quite high participation rates amongst that section of the labour force. This apparent paradox is explained in terms of the different purposes of the early-retirement schemes in the two countries: in Belgium they were primarily part of a strategy to combat (youth) unemployment, in Sweden they had more to do with reforms that sought to accomplish a ,humanisation of work' by softening the abrupt transition from work into retirement.

Bullying among nurses and its effects

INTERNATIONAL NURSING REVIEW, Issue 4 2009
m phd
Background:, The victims of bullying are subjected to being terrorized, annoyed, excluded, belittled, deprived of resources, isolated and prevented from claiming rights. The victims of bullying have decreased job satisfaction, work performance, motivation and productivity. Bullying also negatively affects victims' social relationships inside and outside the institution. Objectives:, This study was conducted as a cross-sectional and descriptive study for the purpose of assessing the workplace, bullying of nurses in Turkey and the effects it has on nursing practices. Method:, The sample was composed of 286 nurses, and all of the respondents were female. The research instrument was a questionnaire in five parts. The first section included the participants' demographic information; the other variables were measured in four categories: psychologically violent behaviours, workload, organizational effects and depression. Findings:, Thirty-seven per cent of the nurses participating in the research had never or almost never encountered workplace bullying behaviour in the last 12 months, 21% of the nurses had been exposed to these behaviours. There were no differences between position and educational level in workplace bullying. Workplace bullying leads to depression, lowered work motivation, decreased ability to concentrate, poor productivity, lack of commitment to work, and poor relationships with patients, managers and colleagues. Conclusion:, Workplace bullying is a measurable problem that negatively affects the psychology and performance of the nurses in this study. [source]


Sleep disturbance experiences among perimenopausal women in Taiwan

JOURNAL OF CLINICAL NURSING, Issue 15 2009
Hsiu-Chin Hsu
Aim., To generate a descriptive theory framework regarding the experiences of sleep disturbances among perimenopausal women in Taiwan. Background., Although studies show that some perimenopausal women are troubled by sleep problems, little information was found about the subjective experiences of sleep disturbances among these women. Research is required to explore women's feelings or perceptions in dealing with their sleep problems. These understandings will be important to help alleviate perimenopausal women's sleep problems. Design., A grounded theory research design was applied. Method., Twenty-one Taiwanese sleep disturbed women, aged 46,57 years, participated in in-depth interviews. Results., ,Getting back a good night's sleep' was the core theme for describing and guiding the process of the women's sleep disturbance experiences. During the process, ,disturbed sleep' was identified as the antecedent condition that included subcategories: easy awakening, difficulty falling asleep, inner worries, physical discomfort and genetic and bodily constitution. Analyses showed five categories (some with subcategories) of the sleep disturbed women: (i) worsening health status , physical exhaustion, impaired social interactions, emotional swings and decreased work performance; (ii) living with lonely nights , self-help and endurance; (iii) a search for resources to relieve sleep difficulties , doctor shopping, trying alternative therapies, exercising and seeking support; (iv) vicious cycle and (v) acceptance of insomnia. Conclusions., Women expected to relieve their sleep disturbance by finding comprehensive counselling or by their body constitution responding to treatment. Healthcare providers need to value women's individual concerns and subjective voices. Providers must seek out sleep counselling instead of simply prescribing drugs for their sleep difficulties. Relevance to clinical practice., It is crucial to integrate perimenopausal sleep care by implementing a multidimensional approach such as sleep assessment laboratories, sleep counselling, complementary alternative medicine, sleep strategies and support groups.

Magistrates' Everyday Work and Emotional Labour

JOURNAL OF LAW AND SOCIETY, Issue 4 2005
Sharyn Roach Anleu
The concept of emotional labour describes the management of emotions as part of everyday work performance. Much of the research in this field has been in relation to jobs in the service sector where (mostly female) employees are required to shape their own feelings in order to make customers or clients feel at ease, comfortable or happy. There has been relatively little attention paid to the importance of emotional labour in professional occupations. This paper examines the emotional labour of magistrates in court. Magistrates must often regulate their own emotions and those of some court users, many of whom are not legally represented and who express a variety of emotions, including anger and distress, and experience social problems that may elicit emotions or emotional responses from the magistrate. The paper reports findings from interviews with over 40 magistrates throughout Australia and begins to address the significance of emotional labour for this branch of the judiciary. [source]


Professional Competence as Ways of Being: An Existential Ontological Perspective

JOURNAL OF MANAGEMENT STUDIES, Issue 7 2009
Jörgen Sandberg
abstract Current theories propose that professional competence is primarily constituted by scientific and tacit knowledge, knowing-in-action, understanding of work or practice. While providing valuable insights we contend that they present a fragmented understanding of professional competence. In particular, they do not adequately explain how central aspects of practice such as knowledge and understanding are integrated into a specific professional competence in work performance. An existential ontological perspective is proposed as offering a more comprehensive and integrative analysis of professional competence. It is explored through an empirical study of corporate lawyers and the findings suggest that professional competence should be understood as ways of being. The results show that different ways of practising corporate law distinguish and integrate a specific understanding of work, a particular self-understanding, other people, and tools into distinct forms of competence in corporate law.

An Exploration of How the Employee,Organization Relationship Affects the Linkage Between Perception of Developmental Human Resource Practices and Employee Outcomes*

JOURNAL OF MANAGEMENT STUDIES, Issue 1 2008
Bård Kuvaas
abstract The purpose of the present study was to examine whether and how the quality of the employee,organization relationship (EOR) influences the relationship between employee perception of developmental human resource (HR) practices and employee outcomes. Analyses of 593 employees representing 64 local savings banks in Norway showed that four indicators of the EOR (perceived organizational support, affective organizational commitment, and procedural and interactional justice) moderated the relationship between perception of developmental HR practices and individual work performance. A strong and direct negative relationship was found between perception of developmental HR practices and turnover intention, but perceived procedural and interactional justice moderated this linkage. No support was found for a mediating role of the EOR indicators in the relationship between perception of developmental HR practices and employee outcomes. Implications and directions for future research are discussed. [source]


Towards a multi-foci approach to workplace aggression: A meta-analytic review of outcomes from different perpetrators,

JOURNAL OF ORGANIZATIONAL BEHAVIOR, Issue 1 2010
M. Sandy Hershcovis
Using meta-analysis, we compare three attitudinal outcomes (i.e., job satisfaction, affective commitment, and turnover intent), three behavioral outcomes (i.e., interpersonal deviance, organizational deviance, and work performance), and four health-related outcomes (i.e., general health, depression, emotional exhaustion, and physical well being) of workplace aggression from three different sources: Supervisors, co-workers, and outsiders. Results from 66 samples show that supervisor aggression has the strongest adverse effects across the attitudinal and behavioral outcomes. Co-worker aggression had stronger effects than outsider aggression on the attitudinal and behavioral outcomes, whereas there was no significant difference between supervisor, co-worker, and outsider aggression for the majority of the health-related outcomes. These results have implications for how workplace aggression is conceptualized and measured, and we propose new research questions that emphasize a multi-foci approach.

Differential effects of strain on two forms of work performance: individual employee sales and creativity

JOURNAL OF ORGANIZATIONAL BEHAVIOR, Issue 1 2002
Linn Van Dyne
In this research, we develop and test a model of the links between psychological strain (subjective experiences of feeling conflict and tension) and work performance. Our model includes two types of strain (work strain and home strain) and two forms of work performance (quantity of individual sales performance and creativity). Thus we acknowledge the importance of work and non-work sources of strain as well as the multidimensional nature of work performance. We test the proposed relationships with data collected over six months from a field sample of 195 hair salon stylists (personal service workers who interact directly with customers and provide services directly to individuals and not to other firms). Results demonstrate a positive relation between work strain and individual employee sales performance and a negative relation between home strain and employee creativity at work. Leader,member exchange moderated the effects of work strain and home strain on creativity. We discuss findings and implications, emphasizing multiple roles, the importance of differentiating types of strain, and the multidimensionality of work performance. We conclude by suggesting that strain may be particularly relevant to work performance of employees in jobs like those in our sample which are characterized by high social interdependence and low task interdependence.

Using Task Clarification, Checklists and Performance Feedback to Improve the Appearance of a Grocery Store

PERFORMANCE IMPROVEMENT QUARTERLY, Issue 2 2003
Leslie Shier
ABSTRACT An intervention package of task clarification, checklists, and posted performance feedback was developed to increase completion of tasks contributing to the appearance of a local grocery store. The intervention package was based on an informal diagnostic assessment that examined antecedents, equipment and processes, knowledge and skills, and consequences in the organizational environment. A multiple baseline design across five departments was utilized to evaluate the effects of the intervention package on employee cleaning behavior related to the appearance of the store. The results suggest overall improvement of task completion across the five departments observed, with substantial increases resulting from application of the intervention. The mean percentage of tasks completed in the deli department increased by 36%; by 93% in the meat department; by 38% in the frozen department; by 25% in the produce department; and by 34% in the front-end department. The average increase of task completion across departments was more than 45%. The results of this study are consistent with those of Anderson, Crowell, Hantula, and Siroky (1988), as well as with La Fleur and Hyten (1995), demonstrating that task clarification, checklists, and feedback have positive effects on work performance.

The Implementation of an Electronic Performance Support System for Teachers: An Examination of Usage, Performance, and Attitudes

PERFORMANCE IMPROVEMENT QUARTERLY, Issue 1 2001
Joi L. Moore
ABSTRACT This study investigated how teachers used an electronic performance support system (EPSS) and whether the usage of this EPSS affected their work performance and attitudes toward computer technology. The findings suggested a framework for the implementation of an EPPS in an educational setting, specifically at a middle school. The data were collected through observations, questionnaires, anecdotal logs, database records, and interviews. Four middle school teachers used the EPSS primarily for completing student progress reports wherein the results indicated that the EPSS decreased the amount of time to perform this task. Computer usage, performance, and attitudes were affected by work responsibilities, accessibility to computers, the change agent, the technology support personnel, as well as the specific characteristics of the EPSS. The teachers' attitudes toward the EPSS and technology in general were affected by their performances when using the system, by interactions with the person responsible for technology support, and by the ability to customize the computer program to fit their needs.

Nurses' Grief Reactions to a Patient's Suicide

PERSPECTIVES IN PSYCHIATRIC CARE, Issue 1 2002
FAAN, Sharon M. Valente PhD
TOPIC. A patient's suicide may threaten the nurse's health and work performance until grief and mourning are transformed. PURPOSE. To examine the literature, bereavement theories, and recommendations for supporting nurses' bereavement. SOURCES. Bereavement literature on Medline, CINAHL, and PsychInfo from 1965,2001, and clinicians' and nurses'responses to a patient's death by suicide. CONCLUSIONS. Nurses need a support system to help them cope with grief after a patient's suicide. Having knowledge of bereavement and using therapeutic support can help prevent burnout or stress and can encourage constructive coping strategies that transform grief. Grieving is facilitated when nurses recognize their own mortality and take time to process their grief. [source]


Treating intermittent allergic rhinitis: a prospective, randomized, placebo and antihistamine-controlled study of Butterbur extract Ze 339

PHYTOTHERAPY RESEARCH, Issue 6 2005
Article first published online: 22 AUG 200
Abstract Background: Intermittent allergic rhinitis (IAR) causes patients distress and impairs their work performance and quality of life. A variety of medicines are used by sufferers whose anguish frequently leads to trying new treatments, increasingly from herbal sources. Methods: Prospective, randomized, double-blind, parallel group comparison study of Butterbur extract (Ze 339; 8 mg total petasine; one tablet thrice-daily), fexofenadine (Telfast 180®, one tablet once-daily) and placebo in 330 patients. Protocol and analysis were according to the latest guidelines on new treatments for allergic rhinitis. The primary efficacy variable was a change in symptoms from baseline to endpoint during daytime. The secondary efficacy variables were: (a) as per primary variable (evening/night); (b) Physician's global assessment; (c) Responder rates. Safety was closely monitored. Findings: Both active treatments were individually significantly superior to placebo (p < 0.001) in improving symptoms of IAR, while there were no differences between the two active treatments (p = 0.37). Superiority to placebo was similarly shown during the evening/night (p < 0.001), by physicians' own assessment and by responder rates. Both treatments were well tolerated. Interpretation: Butterbur Ze 339 and Fexofenadine are comparably efficacious relative to placebo. Despite being a herbal drug, Butterbur Ze 339 has now been subject to a series of well controlled trials and should be considered as an alternative treatment for IAR.

Prevalence of building-related symptoms as an indicator of health and productivity

AMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 10 2006
Raimo Niemelä PhD
Abstract Background The prevalence of building-related symptoms (BRS) is commonly used to characterize the indoor air quality in office buildings. To analyze the costs of building renovation and the improvement of the indoor environment, it is useful to quantitatively relate the prevalence or intensity of BRS to productivity. The intent of this study is to summarize the links between the BRS and productivity, and demonstrate this linkage in two case buildings. Material and Methods A literature was surveyed for studies that measured simultaneously the prevalence or intensity of BRS and subjectively reported or objectively measured productivity. Case studies in two office environments were performed. An association between the prevalence of BRS and productivity of workers in a call center and in an insurance office were investigated. In the first case study, the productivity was expressed using the direct productivity metrics, namely the number of telephone contacts during active working hours while in the second case, the productivity was assessed by using the data concerning sick leave rates. Results Employees who report more BRS also have more often absences which relate to indoor environment quality (IEQ). Their productivity is lower than those who have better IEQ in their offices. Despite uncertainties related to the data concerning recorded sick leave and self-reported productivity, the number of studies showing an association between BRS and productivity or sick leave suggests that such a relationship exists. The present case studies also demonstrated an association between the BRS and the direct productivity. Based on the data from the call center, a reduction of 10%-units in the prevalence of general symptoms (such as fatigue, headache, nausea, etc.) corresponded with a gain of 1.5% in performance. Based on the findings in the insurance company, a reduction of 10%-units in the prevalence of irritation symptoms corresponded with a decrease of 0.7% in the short-term absenteeism. Conclusions A review of 23 studies suggests that a linkage exists between typical BRS and productivity indicators such as task or work performance or absence from work. Quantitative associations between BRS and productivity were demonstrated in two office environments. Quantitative associations between BRS and economic metrics enable cost-benefits analysis. Am. J.

Disability and the Performance Paradox: Can Social Capital Bridge the Divide?

BRITISH JOURNAL OF INDUSTRIAL RELATIONS, Issue 3 2010
Kelly Williams-Whitt
This research captures the physical and social experience of disability by analysing the practical performance problems that arise when an ill or injured employee returns to work, and documenting how those problems are interpreted. The grounded theory approach suggests an alternative to the traditional biomedical or social perspectives on disability. Field research reveals four themes: attendance, disciplinary history, peer interaction and task function. Managerial and co-worker perceptions were significantly affected by interactions that occurred before any disability was known to exist. Historic patterns of social exchange strongly suggest that social capital theory explains problematic work performance. [source]


Rhodiola rosea: A Versatile Adaptogen

COMPREHENSIVE REVIEWS IN FOOD SCIENCE AND FOOD SAFETY, Issue 3 2005
Farhath Khanum
ABSTRACT Rhodiola rosea (rose root) belonging to the family Crassulaceae is a popular medicinal plant in Russia, Scandinavia, and many other countries. Extracts of the roots of this plant have been found to favorably affect a number of physiological functions including neurotransmitter levels, central nervous system activity, and cardiovascular function. It is being used to stimulate the nervous system, decrease depression, enhance work performance, eliminate fatigue, and prevent high-altitude sickness. Most of these effects have been ascribed to constituents such as salidroside (rhodioloside), rosavins, and p-tyrosol. It has also been found to be a strong antioxidant and anticarcinogen due to the presence of several phenolic compounds. Adaptogens are plant extracts that allow an organism to counteract adverse physical, chemical, and biological stressors by generating nonspecific resistance. Adaptogens are known to increase the availability of energy during the day, reduce stressed feelings, increase endurance, and increase mental alertness. This multipurpose medicinal plant (R. rosea), with adaptogenic properties that increase the body's nonspecific resistance and normalize functions, has been traditionally grown and used in Russia and Mongolia. Due to increasing consumer demands toward natural health products and the growing interests in the secondary metabolites of plants and their application in biotechnology and therapy, much focus has been put on the rose root and its medical properties. The rose root imparts normalizing influences on adverse physical, chemical, and biological disturbances but is otherwise innocuous. In India, the plant has been growing wild in the high altitudes of the Himalayas. The Defence Research and Development Organization in India has taken on the responsibilities of its conservation, as well as the development of multiple management practices and the development of health foods, supplements, and nutraceuticals in India.
