Distinguishing Between the Effect of Perceived Organisational Support and Person–Organisation Fit on Work Outcomes
Authors: Ng Catherine , Sarris Aspa 
Published: August 2012

AbstractWhile previous research has contributed to our understanding of the effect of person-organisation fit on a range of job outcomes (e.g., Chatman, 1989; Kristof-Brown & Jansen, 2007; Schneider, 1987), the relationship between person–organisation fit, perceived organisational support and job outcomes, such as job satisfaction and organisation commitment has not been fully explored. Further research examining the relationship between these variables is needed, particularly in organisational settings that experience high turnover such as hospitals. This study examined the relationship between person–organisation fit, perceived organisational support, job satisfaction and organisational commitment among employees in an Australian hospital setting. Person–organisation fit was assessed in terms of the fit, or congruence, between perceived organisational values and ideal organisational values. The study also examined the extent to which perceived organisational support moderated the relationship between person–organisation fit and job satisfaction and organisational commitment. Results showed that person–organisation fit and perceived organisational support were significant predictors of job satisfaction and organisational commitment. However, perceived organisational support was not a moderator in the relationship between person–organisation fit and job satisfaction and organisational commitment. Results also showed that perceived organisational support may be a stronger predictor of job satisfaction and organisational commitment than person–organisation fit, highlighting the importance of providing nursing and support staff with adequate support to carry out their work in hospital settings. The implications of the study are discussed and future research opportunities are highlighted.
A Review of Contemporary Research on the Relationship Between Occupational Stress and Social Support: Where Are We Now?
Authors: Haly Martha Knox 
Published: August 2012

AbstractThe Occupational social support model has been described as producing weak and inconsistent results. There have been assertions that it has lost its popularity as an explanatory construct. However, lack of social support within workplaces has been implicated in the majority of work stress claims and is becoming a focal point of safety prosecutions against Australian employers for failure to provide a psychologically safe workplace. This article presents a review of contemporary (since 1999) cross-sectional and longitudinal studies that measure supervisory or co-worker support as a variable of interest in the published literature. The review examines the theoretical models, as well as general findings associated from over 61 studies. While there is substantial variation in the magnitude of effects, the majority of studies consistently produce positive evidence of the role of social support in offsetting the effects of strain. The review notes several well-constructed longitudinal studies, the increasing popularity of structural equation modelling, and the continued dominance of the Job Demands Control Support Model. The discussion includes consideration of studies where no mitigating effect was found for social support, and concludes that the magnitude of social support effect is determined by the history and context of social support being offered.
Factors Influencing the Planning Undertaken by Women During Pregnancy for their Return to Work After Maternity Leave

Published: August 2012

AbstractThe planning women (N = 199) do during pregnancy for their return to work post birth and the factors that influence employment planning during late pregnancy were investigated in this study. The findings revealed three components of planning: Planning for Childcare, Planning with Partner, and Planning with Employer. Several factors emerged as consistent cross-sectional predictors of these components (work satisfaction, hours worked before commencing maternity leave, anticipated weeks of maternity leave and anticipated hours per week on the return to work). Anticipated support from family and friends, and from the workplace also predicted Planning with Partner and Planning with Employer, respectively. The theoretical and practical implications of these findings are discussed.
A Factor-Analytic Study Exploring the Factors of Co-Worker Cohesion
Authors: von Treuer Kathryn , Fuller-Tyszkiewicz Matthew , Atkinson Barbara 
Published: August 2012

AbstractDespite the applied importance of cohesion within organisational settings, researchers have yet to reach consensus about the dimensionality of group cohesion, and therefore appropriate tools for its measurement. The way that cohesion has generally been conceptualised has changed over time, but the measures appear not to reflect the underlying theory. This deficiency has impeded attempts to explore the relationship between co-worker cohesion and group performance (Beal et al., 2003; Mullen & Copper, 1994). Given inconsistent findings from previous factor analyses of cohesion, the present study employed exploratory means to help clarify the factor structure of cohesion within the workplace. Potential participants were recruited via the researchers' social networks. This snowballing technique led to 236 participants completing the online questionnaire. Exploratory factor analysis revealed four first-order factors of team commitment, friendliness, interpersonal conflict and communication that collectively accounted for 55.17% of the variance shared among the 75 cohesion items. Subsequently, a single higher-order factor was extracted which accounted for over half of the co-variation among the first order factors. This higher-order factor seems to reflect a general cohesion factor, as it was loaded by a diffuse collection of items, including those from the four lower-order factors as well as items that failed to load onto these lower-order factors. While there were similarities between these results and those of previous studies, the present factor structure did not map perfectly onto any of the existing conceptual models of cohesion. This finding highlights the need to incorporate some alternate factors that have previously been given little consideration.
Bullying the Boss: The Prevalence of Upward Bullying Behaviours

Published: August 2012

AbstractThe present study investigated the prevalence of upwards bullying — that is, subordinate-initiated bullying of their supervisor — in two sample groups. Subordinates (n = 491) in this study were either thesis students working under the supervision of an academic advisor or were employees working under a primary supervisor in a variety of occupations. Participants completed a measure of bullying behaviours, the Negative Acts Questionnaire, as part of an online survey. Although the overall prevalence of bullies was low (1.7%), there was a high incidence of bullying behaviour with 70.6% of the sample reporting having engaged in bullying behaviours toward their supervisor in the preceding 6 month period. The incidence of bullying behaviours was lower for the students than for the employees and lower for females than for males. Implications for workplaces are considered.

Published: August 2012

AbstractThe aim of this study is to determine the factors that affect the wellbeing at work of a particular group within the Victorian public sector: those who are directly responsible for the delivery of justice to offenders, namely corrections officers. Corrections staff, as front-line workers in the corrections system, have an important role in the rehabilitation and reintegration of offenders. The study is based on data from The People Matter Survey 2005 that sought to measure Victorian public sector employees' perceptions of how well the public sector values and employment principles were applied within their organisations. In this study we used data from 230 employees from Corrections Victoria who participated in the survey and used multilinear regression to analyse the factors affecting the level of workplace wellbeing. This study found that the most important factors affecting workplace wellbeing of the workers are Fair and Reasonable Treatment (FRT), Accountability (AC), and Senior Management (SM). Other findings included that the levels of workplace wellbeing of bullied or harassed staff was less than non-bullied or harassed staff.

Published: August 2012

BACKGROUND:
The extent to which pandemic H1N1 influenza (pH1N1) differed from seasonal influenza remains uncertain.

METHODS:
By using active surveillance data collected by the Immunization Monitoring Program, Active at 12 Canadian pediatric hospitals, we compared characteristics of hospitalized children with pH1N1 with those with seasonal influenza A. We compared demographics, underlying health status, ICU admission, and mortality during both pandemic waves versus the 2004/2005 through the 2008/2009 seasons; influenza-related complications and hospitalization duration during pH1N1 wave 1 versus the 2004/2005 through the 2008/2009 seasons; and presenting signs and symptoms during both pH1N1 waves versus the 2006/2007 through the 2008/2009 seasons.

RESULTS:
We identified 1265 pH1N1 cases (351 in wave 1, 914 in wave 2) and 1319 seasonal influenza A cases (816 from 2006/2007 through 2008/2009). Median ages were 4.8 (pH1N1) and 1.7 years (seasonal influenza A); P &lt; .0001. Preexisting asthma was overrepresented in pH1N1 relative to seasonal influenza A (13.8% vs 5.5%; adjusted P &lt; .0001). Symptoms more often associated with pH1N1 wave 1 versus seasonal influenza A were cough, headache, and gastrointestinal symptoms (adjusted P &lt; .01 for each symptom). pH1N1 wave 1 cases were more likely to have radiologically confirmed pneumonia (adjusted odds ratio = 2.1; 95% confidence interval = 1.1–3.8) and longer median length of hospital stay (4 vs 3 days; adjusted P = .003) than seasonal influenza A. Proportions of children requiring intensive care and deaths in both pH1N1 waves (14.6% and 0.6%, respectively) were not significantly different from the seasonal influenza A group (12.7% and 0.5%, respectively).

CONCLUSIONS:
pH1N1 in children differed from seasonal influenza A in risk factors, clinical presentation, and length of hospital stay, but not ICU admission or mortality.
Rate my data: quantifying the value of ecological data for the development of models of the terrestrial carbon cycle

Primarily driven by concern about rising levels of atmospheric CO2, ecologists and earth system scientists are collecting vast amounts of data related to the carbon cycle. These measurements are generally time consuming and expensive to make, and, unfortunately, we live in an era where research funding is increasingly hard to come by. Thus, important questions are: “Which data streams provide the most valuable information?” and “How much data do we need?” These questions are relevant not only for model developers, who need observational data to improve, constrain, and test their models, but also for experimentalists and those designing ecological observation networks.Here we address these questions using a model–data fusion approach. We constrain a process‐oriented, forest ecosystem C cycle model with 17 different data streams from the Harvard Forest (Massachusetts, USA). We iteratively rank each data source according to its contribution to reducing model uncertainty. Results show the importance of some measurements commonly unavailable to carbon‐cycle modelers, such as estimates of turnover times from different carbon pools. Surprisingly, many data sources are relatively redundant in the presence of others and do not lead to a significant improvement in model performance. A few select data sources lead to the largest reduction in parameter‐based model uncertainty. Projections of future carbon cycling were poorly constrained when only hourly net‐ecosystem‐exchange measurements were used to inform the model. They were well constrained, however, with only 5 of the 17 data streams, even though many individual parameters are not constrained. The approach taken here should stimulate further cooperation between modelers and measurement teams and may be useful in the context of setting research priorities and allocating research funds.

Published: August 2012

Background: Survival rates in implant dentistry today are high, although late failures do occur for many reasons, including peri‐implant infections. The primary objective of this study is to investigate microbiota around single turned implants after 16 to 22 years. Secondary objectives are to compare teeth and implants and to correlate microbiologic, radiographic, and clinical parameters.Methods: A total of 46 patients with single implants were invited for a clinical examination. Clinical data were collected from implants and contralateral natural teeth. Radiographic bone level was measured around implants. Microbiologic samples were taken from implants, contralateral teeth, and the deepest pocket per quadrant. Samples were analyzed with DNA‐DNA hybridization including 40 species. Statistical analysis was performed using Wilcoxon signed‐rank tests, McNemar tests, and Spearman correlation coefficients with a 0.05 significance level.Results: Mean follow‐up was 18.5 years (range 16 to 22 years). Tannerella forsythia (1.5 × 105) and Veillonella parvula (1.02 × 105) showed the highest concentrations around implants and teeth, respectively. Porphyromonas gingivalis, Prevotella intermedia, and T. forsythia were significantly more present around implants than teeth. Mean counts were significantly higher around implants than teeth for Parvimonas micra, P. gingivalis, P. intermedia, T. forsythia, and Treponema denticola. Total DNA count was correlated to interproximal bleeding index (r = 0.409) and interproximal probing depth (r = 0.307). No correlations were present with plaque index or radiographic bone level.Conclusions: In the present study, bacterial counts around single implants in periodontally healthy patients are rather low. Although pathogenic bacteria are present, some in higher numbers around implants than teeth (five of 40), the majority of implants present with healthy peri‐implant tissues without progressive bone loss.

Published: August 2012

OBJECTIVE
The role of adiponectin in the natural history of diabetes is not well characterized. We set out to characterize prediagnosis trajectories of adiponectin in individuals who develop type 2 diabetes.

RESEARCH DESIGN AND METHODS
In a case-cohort study (335 incident diabetes case and 2,474 noncase subjects) nested in the Whitehall II study, serum adiponectin was measured up to three times per participant (1991–1993, 1997–1999, and 2003–2004). Multilevel models adjusted for age and ethnicity were fitted to assess 13-year trajectories of log-transformed adiponectin preceding diabetes diagnosis or a randomly selected time point during follow-up (year0) based on 755/5,095 (case/noncase) person-examinations.

RESULTS
Adiponectin levels were lower in diabetes case than in noncase subjects (median 7,141 [interquartile range 5,187–10,304] vs. 8,818 [6,535–12,369] ng/mL at baseline, P &lt; 0.0001). Control subjects showed a modest decline in adiponectin throughout follow-up (0.3% per year, P &lt; 0.0001) at higher levels in women than in men (difference at year0: 5,358 ng/mL, P &lt; 0.0001). Female case and early-onset case (age at diagnosis &lt;52 years) subjects had a steeper decline than control subjects (slope difference −1.1% per year, P = 0.001 in females, −1.6% per year in early-onset case subjects, P = 0.034). In men, adiponectin slopes for case and noncase subjects were parallel. The slope differences by diabetes onset were largely attenuated after adjustment for changes in obesity, whereas the sex-specific slope differences were independent of obesity.

CONCLUSIONS
Lower adiponectin levels were observed already a decade before the diagnosis of diabetes. The marked sex difference in trajectories suggests that sex-specific mechanisms affect the association between adiponectin levels and diabetes development.
Insulin Degludec/Insulin Aspart Administered Once Daily at Any Meal, With Insulin Aspart at Other Meals Versus a Standard Basal-Bolus Regimen in Patients With Type 1 Diabetes

Published: August 2012

OBJECTIVE
To evaluate efficacy and tolerability of a co-formulation of insulin degludec and insulin aspart (IDegAsp) with insulin aspart (IAsp) at other meals compared with basal-bolus therapy using insulin detemir (IDet) and IAsp.

RESEARCH DESIGN AND METHODS
Adults (n = 548) with type 1 diabetes (A1C 7.0–10.0%; BMI ≤35.0 kg/m2) were randomized 2:1 in a 26-week, multinational, parallel-group, treat-to-target trial to IDegAsp or IDet. IDegAsp was given with a meal, and IDet was given in the evening, with a second (breakfast) dose added if needed.

RESULTS
Non-inferiority for IDegAsp versus IDet was confirmed; A1C improved by 0.75% with IDegAsp and 0.70% with IDet to 7.6% in both groups (estimated treatment difference IDegAsp − IDet: –0.05% [95% CI –0.18 to 0.08]). There was no statistically significant difference between IDegAsp and IDet in the rates of severe hypoglycemia (0.33 and 0.42 episodes/patient-year, respectively) or overall confirmed (plasma glucose &lt;3.1 mmol/L) hypoglycemia (39.17 and 44.34 episodes/patient-year, respectively). Nocturnal confirmed hypoglycemia rate was 37% lower with IDegAsp than IDet (3.71 vs. 5.72 episodes/patient-year, P &lt; 0.05). Weight gain was 2.3 and 1.3 kg with IDegAsp and IDet, respectively (P &lt; 0.05). Total insulin dose was 13% lower in the IDegAsp group (P &lt; 0.0001). No treatment differences were detected in Health-Related Quality of Life, laboratory measurements, physical examination, vital signs, electrocardiograms, fundoscopy, or adverse events.

CONCLUSIONS
IDegAsp in basal-bolus therapy with IAsp at additional mealtimes improves overall glycemic control and was non-inferior to IDet, with a reduced risk of nocturnal hypoglycemia and fewer injections in comparison with IDet + IAsp basal-bolus therapy.
Association of Serum Ferritin and the Development of Metabolic Syndrome in Middle-Aged Korean Men
Authors: Park Sung Keun , Ryoo Jae-Hong , Kim Min-Gi , Shin Ju-Young 
Published: August 2012

OBJECTIVE
Elevated serum ferritin has been known to be associated with the prevalence of metabolic syndrome (MetS). However, there was no research to examine whether serum ferritin levels have been actually associated with the prospective development of MetS. Accordingly, we carried out a prospective study to evaluate the longitudinal effects of baseline serum ferritin levels on the development of MetS.

RESEARCH DESIGN AND METHODS
A MetS-free cohort of 18,022 healthy Korean men, who had participated in a medical health checkup program in 2005, was followed until 2010. MetS was defined according to the joint interim statement of the International Diabetes Federation Task Force on Epidemiology and Prevention. Cox proportional hazards models were performed.

RESULTS
During 45,919.3 person-years of follow-up, 2,127 incident cases of MetS developed between 2006 and 2010. After adjusting for multiple covariates, the hazard ratios (95% CI) for incident MetS comparing the second quintile to the fifth quintile of serum ferritin levels versus the first quintile were 1.19 (0.98–1.45), 1.17 (0.96–1.43), 1.36 (1.12–1.65), and 1.66 (1.38–2.01), respectively (P for trend &lt;0.001). These associations were apparent in the clinically relevant subgroup analyses.

CONCLUSIONS
Elevated serum ferritin levels were independently associated with future development of MetS during the 5-year follow-up period.

Published: August 2012

OBJECTIVE
To examine whether diabetes genetic risk testing and counseling can improve diabetes prevention behaviors.

RESEARCH DESIGN AND METHODS
We conducted a randomized trial of diabetes genetic risk counseling among overweight patients at increased phenotypic risk for type 2 diabetes. Participants were randomly allocated to genetic testing versus no testing. Genetic risk was calculated by summing 36 single nucleotide polymorphisms associated with type 2 diabetes. Participants in the top and bottom score quartiles received individual genetic counseling before being enrolled with untested control participants in a 12-week, validated, diabetes prevention program. Middle-risk quartile participants were not studied further. We examined the effect of this genetic counseling intervention on patient self-reported attitudes, program attendance, and weight loss, separately comparing higher-risk and lower-risk result recipients with control participants.

RESULTS
The 108 participants enrolled in the diabetes prevention program included 42 participants at higher diabetes genetic risk, 32 at lower diabetes genetic risk, and 34 untested control subjects. Mean age was 57.9 ± 10.6 years, 61% were men, and average BMI was 34.8 kg/m2, with no differences among randomization groups. Participants attended 6.8 ± 4.3 group sessions and lost 8.5 ± 10.1 pounds, with 33 of 108 (30.6%) losing ≥5% body weight. There were few statistically significant differences in self-reported motivation, program attendance, or mean weight loss when higher-risk recipients and lower-risk recipients were compared with control subjects (P &gt; 0.05 for all but one comparison).

CONCLUSIONS
Diabetes genetic risk counseling with currently available variants does not significantly alter self-reported motivation or prevention program adherence for overweight individuals at risk for diabetes.
