Brand communities are of great interest to marketers, and motivating participation in these communities has been explored from many different perspectives. The current study examined how men and women differ in the motives (i.e., entertainment, receiving and sharing information, social integration, self-discovery, and status enhancement) behind their behavior rather than the more often discussed difference between men and women regarding actual behavior and attitudes. A survey sample (N = 195) was collected to explore this, and the data were analyzed with PLS-SEM. The model of participation motives for women was compared to the model for men, and differences (and similarities) were analyzed. The findings indicate that the genders have different motivations to participate in these brand communities. Specifically, the self-discovery and sharing information motives were significantly more important for males, while the social integration motive was significantly more important for females. However, the genders had no differences regarding entertainment, receiving information, and status enhancement motives. [ABSTRACT FROM AUTHOR]

Relevant literature indicates that one's perception of future time is related to their psychological well-being, particularly for older adults. However, more research is needed to understand this relationship in the context of COVID-19. Older adults may be especially vulnerable to the psychological impacts of the pandemic, but findings on their psychological well-being during COVID-19 are mixed. The current study examines relationships between Future Time Perspective (FTP), COVID-19 impact, and Psychological Well-Being, and how these variables change over 8 months during the earlier period of the pandemic. The current study explored these relationships in a sample of older women in Ontario, Canada, at two time points (Mage = 70.39 at T1), who completed online Qualtrics surveys. We used hierarchical linear regressions to test our expectations that COVID-19 impact would be negatively associated with psychological well-being, whereas FTP would be positively associated with psychological well-being, and that FTP would moderate the relationship between COVID-19 impact and psychological well-being. We found partial support for these hypotheses. Our knowledge of the relationship between FTP and psychological well-being would benefit from research that continues to explore different contexts and diverse samples, to enhance understandings of important differences.

This study aims to eliminate an embedded data bias in testing the J-curve hypothesis in relevant literature. In all previous trade models about the J-curve, the bilateral trade balance (BTB) ratio, as the dependent variable, is generated and used based on total exports data, i.e. as total exports over total import. However, total exports are the sum of domestic exports and re-exports, and some countries also re-export to their partners. Furthermore, the dynamics and impacts of changing exchange rates on export volumes of domestically produced goods may differ from those on re-exported goods. Therefore, in this study, in testing the asymmetric J-curve hypothesis, we, for the first time, re-define two new proposed forms of BTBs, namely, domestic-export-based J-curve hypothesis BTB and re-export-based J-curve hypothesis BTB, based on domestic exports and re-exports, respectively, for USA–Canada trade. The main finding shows that the numbers of industries that support the asymmetric J-curve concerning these two forms of BTBs are entirely different. While the J-curve is supported by domestic-export-based J-curve hypothesis BTB for 27 industries, it is supported by re-export-based J-curve hypothesis BTB for 38. This support is 22 for the total-export-based J-curve hypothesis BTB. [ABSTRACT FROM AUTHOR]

Family care-giving is associated with social isolation, which can lead to adverse health and wellbeing outcomes among family care-givers. The role of geographic distance in care-giver social isolation (CSI) is unclear and has received mixed research findings. Framed by the Ecological Model of Caregiver Isolation, this study examined the relationship between geographic distance and CSI, including the interaction between geographic distance and care-giving intensity for CSI. Linear regression and analysis of covariance were used to test these hypotheses using a sub-set of family care-givers from the 2012 Canadian General Social Survey (N = 2,881). Care-givers living a short distance from receivers reported lower levels of social isolation than co-resident, moderate-distance and long-distance care-givers. Being involved in higher-intensity care-giving as the primary care-giver, undertaking more care-giving tasks and providing care more frequently resulted in higher CSI scores. Long- and moderate-distance care-givers reported greater CSI than co-resident and short-distance care-givers only when providing higher-intensity care-giving. Employing a granulated measure of geographic distance positioned within an ecological framework facilitates an understanding of the nuanced association between geographic proximity and CSI. Furthermore, the identified interaction effects between geographic distance and care-giving intensity on CSI further explicate the complexity of care-giving experiences. The findings are relevant for programmes supporting care-givers in different contexts, especially distance care-givers. [ABSTRACT FROM AUTHOR]

Introduction: In early 2020, North American jurisdictions required households (e.g., romantic couples) to isolate together to help mitigate the spread of COVID-19. This study provides a first look at the interplay of depressive symptoms and conflict behaviors among isolating couples, including tests of predictions of the stress generation hypothesis. Methods: Mixed-gender couples residing in Canada (N = 711) completed online measures across two waves. We used the actor-partner interdependence mediation model, with Wave 1 depressive symptoms as the predictor, Wave 1 conflict enactment as the mediator, and Wave 2 depressive symptoms as the outcome. Results: Depressive symptoms showed stability across Wave 1 and 2. Wave 1 depressive symptoms showed associations with Wave 1 conflict enactment. For men (but not women), Wave 1 conflict enactment was associated with their own and their partner's Wave 2 depressive symptoms. For both partners, Wave 1 conflict enacted by men mediated the association between Wave 1 depressive symptoms and Wave 2 depressive symptoms. Discussion: Our study confirms and extends the stress generation hypothesis to the pandemic context, showing that depressive symptoms may partially contribute to conflict for isolating couples and that conflict behaviors enacted by men toward their partner can exacerbate depressive symptoms in both partners.

Background: The supination resistance test (SRT) is a kinetic test used in clinical and research contexts to estimate the amount of force required to supinate the foot. Previous studies either used a manual, less reliable version of this test or a more reliable instrumented version, but with devices inconvenient for clinical use. The clinically available Keystone device has been developed for the SRT, and could be better suited for clinical purposes. The objective of this study is to determine the intrarater and interrater reliability of the Keystone device for the SRT. Method: Thirty young adults underwent two prospective experimental sessions, 1 week apart, during which SRT measures with the Keystone device were registered. Intrarater and interrater reliability were calculated using intraclass correlation coefficients (ICC), standard error of measurement (SEM), minimal detectable difference (MDD) and limits of agreements (LoA). Results: The intrarater reliability of the SRT was good (ICC = 0.86, p < 0.001). The SEM, MDD and 95% LoA were 7.3, 20.4 and −31.6–14.3 N, respectively. The interrater reliability of the SRT was good (ICC = 0.76, p < 0.001). The SEM, MDD and 95% LoA were 9.0, 24.9 and −36.6–24.9 N, respectively. Conclusion: The Keystone device is a reliable tool that can be used in clinical and research contexts. Prospective studies aiming to determine if SRT measures are predictors of musculoskeletal injuries or if they can predict the effects of external supports on the biomechanics of the foot and ankle are warranted.

Background Diagnostic errors unfortunately remain common. Electronic differential diagnostic support (EDS) systems may help, but it is unclear when and how they ought to be integrated into the diagnostic process. Objective To explore how much EDS improves diagnostic accuracy, and whether EDS should be used early or late in the diagnostic process. Setting 6 Canadian medical schools. A volunteer sample of 67 medical students, 62 residents in internal medicine or emergency medicine, and 61 practising internists or emergency medicine physicians were recruited in May through June 2020. Intervention Participants were randomised to make use of EDS either early (after the chief complaint) or late (after the complete history and physical is available) in the diagnostic process while solving each of 16 written cases. For each case, we measured the number of diagnoses proposed in the differential diagnosis and how often the correct diagnosis was present within the differential. Results EDS increased the number of diagnostic hypotheses by 2.32 (95% CI 2.10 to 2.49) when used early in the process and 0.89 (95% CI 0.69 to 1.10) when used late in the process (both p<0.001). Both early and late use of EDS increased the likelihood of the correct diagnosis being present in the differential (7% and 8%, respectively, both p<0.001). Whereas early use increased the number of diagnostic hypotheses (most notably for students and residents), late use increased the likelihood of the correct diagnosis being present in the differential regardless of one's experience level. Conclusions and relevance EDS increased the number of diagnostic hypotheses and the likelihood of the correct diagnosis appearing in the differential, and these effects persisted irrespective of whether EDS was used early or late in the diagnostic process.

The stylonurid eurypterid Leiopterella tetliei Lamsdell, Braddy, Loeffler, and Dineley, 2010 (Chelicerata: Eurypterida: Rhenopteridae) from the Early Devonian (Lochkovian) of Nunavut in Arctic Canada is redescribed. Restudy of the holotype under polarized light revealed a labrum, epistomal sutures, prosomal appendage III, and deltoid plates anterior to the genital appendage. An additional new specimen preserves the distal podomeres of appendage VI and gradually tapering opisthosomal tergites. The characters resolved here support the hypothesis that L. tetliei was relatively basal within the wider Stylonurina clade, with its tapering postabdomen supporting a more basal position within Rhenopteridae than previously suggested.

Understanding how climate change impacts trailing‐edge populations requires information about how abiotic and biotic factors limit their distributions. Theory indicates that socially mediated Allee effects can limit species distributions by suppressing growth rates of peripheral populations when social information is scarce.The goal of our research was to determine if socially mediated Allee effects limit the distribution of Canada warbler Cardellina canadensis at the trailing‐edge of the geographic range.Using 4 years of observational data from 71 sites and experimental data at 10 sites, we tested two predictions of the socially mediated range limitation hypothesis: (a) local growth rates should be positively correlated with local density and (b) the addition of social cues immediately outside the trailing‐edge range boundary would result in colonization of formerly unoccupied habitat and increased growth rates. During the third breeding season, social cues were experimentally added at 10 formerly unoccupied sites within and beyond the species' local range margin to determine if the addition of social information could increase density and effectively expand the species' range.No experimental sites were colonized after adding social cues and no evidence of Allee effects was found. Rather, temperature, precipitation and negative density dependence strongly influenced population growth rates.Although theoretical models indicate that the presence of socially mediated Allee effects at species range boundaries could increase the rate of climate‐induced range shifts and local extinctions, empirical results from the first test of this hypothesis suggest that Allee effects play a minimal role in limiting species' distributions.

Objective: Evidence shows that recent immigrants are healthier than the native-born population, a phenomenon known as the healthy immigrant effect. With increasing duration of stay, this health gap significantly narrows as immigrants' health deteriorates to either resemble or become worse than the host population. However, little is known about the category of immigrants for whom this decline is most pronounced since the extant research largely considers immigrants as a homogeneous group, thus overlooking important racial/ethnic differences. Design: Using data from the 2014 Canadian Community Health Survey (CCHS), we categorised immigrants by race/ethnicity and duration of stay in Canada and compared them to their native-born white Canadian counterparts on the likelihood of having a chronic health condition, using type 2 diabetes (T2D) as a case. Results: In the base model, recent visible minority (i.e. non-white or non-Caucasian) immigrants and recent white immigrants were less likely than the native-born white Canadian population to have T2D (recent visible minority immigrants OR = 0.46, CI = 0.27–0.79, p = 0.005; recent white immigrants OR = 0.26, CI = 0.11–0.64, p = 0.003). The odds of having T2D were significantly higher for long-term immigrants than the native-born white Canadian population (long-term visible minority immigrants OR = 1.59, CI = 1.27–2.00, p = 0.000; long-term white immigrants OR = 1.74, CI = 1.44–2.10, p = 0.000). In the multivariate model, long-term visible minority immigrants were about 2.3 times more likely than their white Canadian born counterparts to have T2D (CI = 1.86–2.96, p = 0.000). Long-term visible minority immigrants were about 2.1 times more likely than long-term white immigrants to have T2D (CI = 1.49–2.94, p = 0.000) Conclusion: Immigrants' health deterioration varies significantly across ethnic categories in Canada. Interventions for facilitating the integration of visible minority immigrants may help reduce these health inequities. [ABSTRACT FROM AUTHOR]

This study tests the theoretically informed assumption that intimate partner violence (IPV) and animal abuse so frequently co-occur because animal maltreatment is instrumentalized by abusers to harm human victims. Using data from a survey of abused women in Canadian shelters, we find that threats to harm "pets," emotional animal abuse, and animal neglect are clearly perceived by these survivors as being intentionally perpetrated by their abuser and motivated by a desire to upset and control them; the findings related to physical animal abuse are not as straightforward. Building on these findings, we propose a more nuanced theorizing of the coexistence of animal maltreatment and IPV. [ABSTRACT FROM AUTHOR]

This article applies new insights into business strategies and high-performance work systems (HPWSs) to examine why organizations adopt work-life balance programs (WLBPs). Results indicate that a product leadership business strategy is positively related to the likelihood of adopting WLBPs, whereas a cost leadership business strategy is negatively related to the adoption of these programs. Moreover, our analyses establish a mediating role of HPWSs in the relationship between business strategies and the adoption of WLBPs. Our results also demonstrate that different industries vary in adoption of work-life balance programs. This supports the institutional theory of organizational responsiveness to work-life balance issues. We tested our hypotheses with two waves of the nationally representative Canadian Workplace and Employee Survey. Implications and specific suggestions for human resource practitioners are discussed. © 2012 Wiley Periodicals, Inc. [ABSTRACT FROM AUTHOR]

There is sound evidence that increased level of peer support is linked negatively with youth vulnerably to internalizing and externalizing problems. Conversely, victimization by peers is associated positively with youth adjustment difficulties. The current study examines the mediating role of victimization in the association between classmates' support and internalizing and externalizing behaviors, and the moderating role of gender in that association. The study is based on a sample of 243 7th grade Canadian adolescents. The results show that classmates' support has a unique contribution to reduced adolescents' internalizing behaviors above and beyond the effects of parental and teachers' support. This association was partially mediated by youth victimization. Classmates' support was a stronger predictor of internalizing behaviors among females compared to males. With respect to externalizing behaviors, the results indicated that while classmates' support has no direct association with that outcome, parental support plays a central role in predicting externalizing behaviors. The association between classmates' support and externalizing behavior was fully mediated by youth victimization. The current study highlights the importance of support by peers, with whom they interact on a regular basis, to adolescents' well-being and functioning. The results also indicate that parents are still significant figures in adolescents' lives. Those facts should be taken into account when intervening with young people. [ABSTRACT FROM AUTHOR]

Amongst the types of problem faced by production managers in a wide variety of Canadian industries, those concerned with growth and change are encountered frequently and are especially severe in small firms. This paper proposes and tests the hypothesis that as small companies grow they pass through alternating phases of good and poor performance. During the latter phases there is a high probability of failure brought about by common problems in a homogeneous group of small companies in an industry. The analysis of data so far supports the hypothesis in commercial printing firms of up to 70 employees, but requires modification for larger companies. [ABSTRACT FROM AUTHOR]

The diffusion of the Web 2.0 has made it possible for patients to exchange on online health communities, defined as computer-mediated communities dedicated to health topics, wherein members can build relationships with other members. It is now acknowledged that online health communities provide users not only with medical information but also with social support with no time or geographical boundaries. However, in spite of their considerable interest, there is still a paucity of research as to how online health communities alter the patient–physician relationship. This research aims at filling this gap and examines how online health communities, while providing users with computer-mediated social support and empowerment, impact the patient–physician relationship. Six hypotheses are proposed and tested. A survey was developed and 328 responses were collected from online patient groups in Canada in 2016. The data were analysed using structural equation modelling. All but one hypothesis are validated. The results show that user computer-mediated social support positively influences user empowerment and participation during the consultation, which in turn determines user commitment to the relationship with the physician. Importantly and contrary to our expectations, user empowerment is found to be significantly but negatively related to user commitment with the physician. [ABSTRACT FROM AUTHOR]

The preparation hypothesis posits that women's genital responses (vasocongestion and lubrication) occur automatically in the presence of any sexual stimulus to prevent injuries from sexual activities. It follows that women's genital responses should be easily conditioned to non-sexual cues that reliably predict impending sexual activities. It has been difficult, however, to demonstrate classical conditioning of genital responses in women in the laboratory. In the current study, we used music as an auditory conditioned stimulus (CS) and vignette narrations of consensual sex, non-consensual sex, and neutral (nonsexual) interactions as unconditioned stimuli (US). Eighteen women (range = 18-27 years, M = 21.9 years, SD = 2.2 years,) and 18 men (range = 19-29 years, M = 22.8 years, SD = 2.8 years) were exposed to three neutrallyrated classical music pieces, each paired with a different type of vignette. Participants were exposed to 3 pre-acquisition trials, 12 acquisition trials, and a minimum of 9 extinction trials. After each trial, participants were asked to rate the CS (or the US in CS-US pairings) on pleasantness, anxiousness, and perceived sexual arousal. Vaginal photoplethysmography and penile plethysmography were used to assess changes in genital responses. The sexual vignettes produced genital responses and the nonsexual vignettes did not. We did not observe conditioning of genital responses to music in either sex, but did so for men's and women's feelings of sexual arousal toward songs paired with a consensual sex story. The results were not consistent with the preparation hypothesis. [ABSTRACT FROM AUTHOR]

The article focuses on a study conducted on the judgment of chief executive officers' (CEOs) leadership ability from their facial appearance.

Background Emetophobia (fear of vomiting) is an anxiety disorder in which individuals report clinical levels of fear that they may vomit or be exposed to the vomit of others. The prevalence of comorbidity of emetophobia with other conditions has previously only been investigated using self-report instruments. Method Sixty-four adults with emetophobia participated in an online structured clinical diagnostic interview assessing the presence of emetophobia and other conditions. Results Higher comorbidity for depression, generalized anxiety disorder, panic disorder, social anxiety disorder and obsessive-compulsive disorder were found in participants compared with general population norms. Conclusions Emetophobia is commonly comorbid with other anxiety and depressive disorders. Comorbidity rates, when assessed using a structured clinical interview, were lower than previously reported using self-report alone. Copyright © 2015 John Wiley & Sons, Ltd. Key Practitioner Message Emetophobia (specific phobia of vomiting) is a clinical fear of vomiting., Individuals with emetophobia show high comorbidity with other anxiety and mood disorders., The most common comorbid conditions were generalized anxiety disorder, panic disorder, hypochondriasis and obsessive-compulsive disorder., Clinicians should ensure that they assess for the presence of comorbid conditions when treating emetophobia.

Stigma appears to influence emotional distress and well-being in cancer survivors, but cross-cultural differences have been ignored. Previous studies suggest that stigma may be especially relevant for survivors of Asian origin. However, their study designs (e.g. focused on female cancers, qualitative designs, and an absence of comparison groups) limit the strength of this conclusion. We hypothesized that (1) Asian-born Chinese immigrants (AI) would report more perceived cancer-related stigma than Western-born Caucasians (WBC); and (2) the impact of stigma on emotional distress and well-being would be greater in AI as compared to WBC. Head and neck cancer survivors (n = 118 AI andn = 404 WBC) completed measures of well-being, emotional distress, and a three-item indicator of stigma in structured interviews. The majority of respondents (59%) reported one or more indicators of stigma. Stigma correlated significantly with emotional distress (r = .13,p = .004) and well-being (r = −.09,p = .032). Contrary to our hypotheses, WBCs and AIs did not differ in reported stigma nor did we detect differences in its psychosocial impact. Stigma exerts a deleterious psychosocial impact on head and neck cancer survivors. It did not differ significantly between AI and WBC survivors. [ABSTRACT FROM AUTHOR]

Self-efficacy is arguably the strongest correlate of physical activity, yet some researchers suggest this is because the construct confounds ability with motivation. We examine a more circumscribed construct, called perceived capability (PC), meant to measure ability but not motivation and propose that the construct will not be related to unskilled physical activities but may be linked to skilled behaviors. The purpose of this paper was to examine whether a PC construct can be stripped of motivation using a vignette approach in both walking and resistance training behaviors. Participants were a random sample of 248 university students, who were then randomly assigned to either answer resistance training or walking behavior questions. Both groups completed a PC measure and reasons for their answer before and after reading a vignette that clarified the phrasing of capability to a literal use of the term. PC was significantly (p < .01) higher post- compared to pre-vignette and the differences were greater (p < .01) for walking than for resistance training. PC had significantly (p < .01) smaller correlations with intention and self-reported behavior post-disambiguation, which resulted in a null relationship with walking but a small correlation with resistance training behavior. When PC was combined with intention to predict behavior, however, there was no significant (p > .05) difference in the amount of variance explained pre- to post-vignette. Thought listing showed that participants did not report capability barriers to walking and over half of the sample construed capability as motivation/other priorities pre-vignette. The findings support use of a vignette approach for researchers who wish to disentangle the assessment of PC from motivation while creating no overall loss in explained variance of physical activity.

Objectives:Although some individual and organizational contributors to person-centred care or quality of care have been studied, they have rarely been examined together. Our goal was to investigate the association of personal and organizational–environmental characteristics with self-reported person-centred behaviours in long-term residential care settings. Method:We asked 109 long-term care staff from two Canadian long-term care homes to complete scales assessing self-reported person-centred care, organizational support for person-centred care, beliefs about personhood in dementia, and burnout. Independent variables included four employee background characteristics (age, gender, occupation, and years of education), beliefs about personhood in dementia, burnout, and three aspects of organizational support for person-centred care (the physical environment of residents, collaboration on care, and support from management). Dependent variables included five aspects of person-centred care: autonomy, personhood, knowing the person, comfort care, and support for relationships .We used multiple linear regression analysis and changes inR2to test variable associations. Results:Including organizational variables in regression models resulted in statistically significant (p< .05) changes inR2for each of the five dependent variables. Including personal variables resulted in statistically significant changes inR2for some dependent variables, but not others. In particular, including employee background characteristics resulted in a statistically significant change inR2for comfort care, and including beliefs about personhood and burnout resulted in statistically significant changes inR2for personhood but not for other dependent variables. Conclusion:Organizational characteristics are associated with several aspects of person-centred dementia care. Individual characteristics, including gender, beliefs about personhood, and burnout, appear to be more important to some aspects of person-centred dementia care (e.g., respect for personhood and comfort care) than others.

Alcoholism is a highly stigmatized condition, with both alcohol-dependent individuals and family members of the afflicted experiencing stigmatization. This study examined the severity of a parent’s alcoholism and family topic avoidance about alcohol as two factors that are associated with family members’ perceptions of stigma. Three dimensions of stigma were considered: discrimination stigma, disclosure stigma, and positive aspect stigma. In addition, this study assessed associations between perceived stigmatization and individuals’ experiences of depressive symptoms, self-esteem, and resilience. Adult children of alcoholics (N = 622) were surveyed about family conditions, perceived stigma, and their emotional and psychological well-being. Regression analyses revealed that the severity of a parent’s alcoholism predicted all three types of stigma for females, but not for males. In addition, family topic avoidance about alcohol predicted all types of stigma for males and discrimination stigma and positive aspect stigma for females. With few exceptions, the three types of stigma predicted depressive symptoms, self-esteem, and resilience for both male and female adult children of alcoholics. The results are discussed in terms of their implications for promoting a family environment that mitigates stigma and encourages emotional and psychological well-being. In 2012, approximately 3.3 million deaths worldwide were due to the harmful use of alcohol (World Health Organization [WHO], 2014). Individuals who abuse alcohol are susceptible to a variety of negative health outcomes (Rehm et al., 2009) and display inappropriate social behaviors (Klingemann, 2001; Schomerus et al., 2011a). General societal perceptions tend to characterize alcohol-dependent individuals as irresponsible and lacking in self-control (Schomerus et al., 2011b). Research in the United Kingdom found that 54% of the population believes alcohol-dependent individuals are personally to blame for their own problems (Crisp, Gelder, Goddard, & Meltzer, 2005). In the United States, a person’s own bad character or the way they were raised are more likely to be identified as reasons for alcoholism than they are for other types of mental illness (Schnittker, 2008). In addition, people prefer greater social distance between themselves and alcoholics than between themselves and people with mental illness (Crisp et al., 2005). The negative social perceptions of alcoholics likely contribute to feelings of stigma (Room, 2005). Not only does stigma affect the afflicted individual, but also members of his or her family (WHO, 2014). Children of parents with an alcohol dependency may be reluctant to discuss a parent’s alcoholism with others if they feel pressured to keep it a secret or to avoid negative stereotypes (Afifi & Olson, 2005; Burk & Sher, 1990; Caughlin & Petronio, 2004; Lam & O’Farrell, 2011). Thus, the stigma of a parent’s alcoholism may prevent children from addressing concerns and coping with their surroundings. [ABSTRACT FROM PUBLISHER]

In vision, typically-developing (TD) individuals perceive 'global' (whole) before 'local' (detailed) features, whereas individuals with autism spectrum disorder (ASD) exhibit a local bias. However, auditory global-local distinctions are less clear in ASD, particularly in terms of age and attention effects. To these aims, here ASD and TD children judged local and global pitch structure in nine-tone melodies. Both groups showed a similar global precedence effect, but ASD children were less sensitive to global interference than TD children at younger ages. There was no effect of attention task. These findings provide novel evidence of developmental differences in auditory perception and may help to refine sensory phenotypes in ASD. [ABSTRACT FROM AUTHOR]

The popular press reports anecdotal benefits of organizational initiatives that are designed to improve employees' work-life balance and wellness, but the long-term impact of these initiatives on firms' financial performance is unknown. Our longitudinal study of publicly traded Canadian organizations uses the strategic human resources management framework to explain why these initiatives may affect their financial performance. We use an exploratory factor analysis of three waves of archival data to identify two types of initiatives and regression to measure their impact on return on assets (ROA). Our findings suggest that, after 2 years, health promotion initiatives significantly decreased ROA, while work-life balance initiatives significantly increased it. Both effects became non-significant over the longer term. [ABSTRACT FROM AUTHOR]

Purpose To determine the association between supervisors' leadership style and autonomy and supervisors' likelihood of supporting job accommodations for back-injured workers. Methods A cross-sectional study of supervisors from Canadian and US employers was conducted using a web-based, self-report questionnaire that included a case vignette of a back-injured worker. Autonomy and two dimensions of leadership style (considerate and initiating structure) were included as exposures. The outcome, supervisors' likeliness to support job accommodation, was measured with the Job Accommodation Scale (JAS). We conducted univariate analyses of all variables and bivariate analyses of the JAS score with each exposure and potential confounding factor. We used multivariable generalized linear models to control for confounding factors. Results A total of 796 supervisors participated. Considerate leadership style (β = .012; 95 % CI .009-.016) and autonomy (β = .066; 95 % CI .025-.11) were positively associated with supervisors' likelihood to accommodate after adjusting for appropriate confounding factors. An initiating structure leadership style was not significantly associated with supervisors' likelihood to accommodate (β = .0018; 95 % CI −.0026 to .0061) after adjusting for appropriate confounders. Conclusions Autonomy and a considerate leadership style were positively associated with supervisors' likelihood to accommodate a back-injured worker. Providing supervisors with more autonomy over decisions of accommodation and developing their considerate leadership style may aid in increasing work accommodation for back-injured workers and preventing prolonged work disability.

This study examines the role of perceived shared understanding with regard to team performance, taking into account the motivational mechanisms (i.e., group potency and team effort) involved in this relationship and the moderating role of task routineness. Using a multisource approach and a team-level design, we collected data from 101 teams (i.e., 381 members and their 101 immediate superiors) working in a Canadian public safety organization. The results support the mediating role of group potency and team effort in the relationship between perceived shared understanding and team performance. Moreover, the results show that the relationship between team effort and team performance is moderated by task routineness, such that this relationship is stronger when task routineness is high. On the whole, the findings of this study help to better understand why and under what circumstances perceived shared understanding may enhance team performance. [ABSTRACT FROM AUTHOR]

ABSTRACT Many scholars have proposed that parent-child attachment security should favor child sleep. Research has yet, however, to provide convincing support for this hypothesis. The current study used objective measures of sleep and attachment to assess the longitudinal links between mother-child attachment security and subsequent sleep, controlling for child dependency. Sixty-two middle-class families (30 girls) were met twice, when children were 15 months (Wave 1; W1) and 2 years of age (Wave 2; W2). At W1, mother-child attachment was assessed with the observer version of the Attachment Q-Sort. At W2, children wore an actigraph monitor for 72 hr. Results indicated that children more securely attached to their mothers subsequently slept more at night and had higher sleep efficiency, and these predictions were not confounded by child dependency. These findings suggest a unique role for secure attachment relationships in the development of young children's sleep regulation, while addressing methodological issues that have long precluded consensus in this literature.

Primary health care (PHC) can improve the health of women who have experienced intimate partner violence; yet, access to and fit of PHC services may be shaped by income and racialization. We examined whether income and racialization were associated with differences in PHC service use, unmet needs, fit with needs, and mental and physical health in a sample of 286 women who had separated from an abusive partner. Mothers, unemployed women, and those with lower incomes used more PHC services and reported a poorer fit of services. Poorer fit of services was related to poorer mental and physical health.

An introduction is presented in which the guest editor discusses the article on the analysis of data from the Canadian Vaccine Effectiveness (VE) network providing support for the antigenic distance hypothesis as a predictor of the possible inhibitory affect of prior flu vaccination.

Relatively little attention has been paid to understanding and addressing the potential health-related barriers faced by older workers to stay at work. Using three representative samples from the Canadian Community Health Survey, we examined the relationship between seven physical chronic conditions and labour market participation in Canada between 2000 and 2005. We found that all conditions were associated with an increased probability of not being able to work due to health reasons. In our adjusted models, heart disease was associated with the greatest probability of not working due to health reasons. Arthritis was associated with the largest population attributable fraction. Other variables associated with not being able to work due to health reasons included older age, female gender and lower educational attainment. We also found particular combinations of chronic conditions (heart disease and diabetes; and arthritis and back pain) were associated with a greater risk than the separate effects of each condition independently. The results of this study demonstrate that chronic conditions are associated with labour market participation limitations to differing extents. Strategies to keep older workers in the labour market in Canada will need to address barriers to staying at work that result from the presence of chronic conditions, and particular combinations of conditions.

The effects of maternal responsiveness on infant responsiveness and behavior in the Still-Face Task were longitudinally examined through infants' first 3 months. Maternal vocal responsiveness and infant vocal and smiling responsiveness significantly increased when infants were 2 months of age. Mothers showed continuity of individual differences in vocal responsiveness from the infants' newborn period. Maternal responsiveness predicted infant responsiveness within and across sessions. Compared with infants with low-responsive mothers, infants with high-responsive mothers were more attentive and affectively engaged during the Still-Face Task from 1 month of age. Infants with high-responsive mothers discriminated between the task phases with their smiling at 1 month, a month before infants with low-responsive mothers did so. Infants in both groups discriminated between the phases with their attention and nondistress vocalizations throughout their first 3 months. Results suggest that maternal responsiveness influences infant responsiveness and facilitates infants' engagement and expectations for social interaction. [ABSTRACT FROM AUTHOR]

Health anxiety is a persistent fear of illness or disease that often involves the misinterpretation of bodily symptoms as signs of serious illness. Evidence shows that health anxiety affects a proportion of women following a diagnosis of breast cancer, but there are some limitations to how health anxiety has been measured. The objectives of this study were to (1) provide an estimate of clinically elevated health anxiety in women after a diagnosis of breast cancer using a validated measure appropriate for medical populations and (2) understand patient, disease, and anxiety/vulnerability variables that predict health anxiety in this group. Canadian women (n = 137) diagnosed with breast cancer within the past five years completed an online survey measuring health anxiety, along with patient, disease, and anxiety/vulnerability variables. Clinically significant health anxiety was reported by 23.4% of the sample. The regression model revealed that younger age, more advanced stage of breast cancer, increased cognitive anxiety sensitivity, and greater body vigilance were significant unique predictors of health anxiety. These findings highlight that a proportion of women report substantial health anxiety following breast cancer diagnosis, with a combination of patient, disease, and anxiety/vulnerability variables associated with the experience. Further research is needed to better understand the impact of health anxiety in this population. [ABSTRACT FROM PUBLISHER]

Three different identity styles among youth are known to be associated with a variety of health-related issues but the association of these identity styles with sexual health has not been investigated. This study documented the identity styles of 657 Canadian students in their teens; the distribution of identity styles was: information-seeking (32.9%); normative (23%); and diffuse (44.1%). Twenty percent of the students reported that they were currently sexually active. Youth with a diffuse identity style were significantly more likely to report being sexually active than those with an information-seeking identity style. Similar associations with identity styles were investigated in relation to student's comfort communicating about sexuality, sexual assertiveness, and potential for sexual risk behaviour and self-efficacy. The findings are discussed in relation to personality characteristics known to be associated with the three identity styles. Educators and counsellors can apply the results to better address the educational needs, social skills, behaviours, and goals of youth according to their differing identity styles.

Three complementary models of how peer relationship problems (exclusion and victimization) and aggressive behaviors relate to prospective levels of internalizing problems are examined. The additive risks model proposes that peer problems and aggression cumulatively increase risks for internalizing problems. The reciprocal risks model hypothesizes that peer problems and aggression transact over time and mediate the effects of each other on prospective internalizing problems. Last, the internalizing risks model proposes that, in addition to aggressive behaviors, prior internalizing problems also provoke peer problems that, in turn, further elevate risks for prospective internalizing problems. Data came from a sample of 453 low-income, ethnically diverse children in kindergarten to Grade 3 who were assessed 3 times over 1 school term (in January, March and June). Findings supported the internalizing risks model. Four key pathways were found to increase risks for internalizing problems by the end of the school year; 2 of these routes were rooted in aggressive behaviors, and 3 paths operated indirectly via levels of peer problems in the spring. Children who were initially aggressive became excluded by peers by the spring, whereas children who initially showed more symptoms of depression and anxiety became victimized by peers by the spring. In turn, both peer exclusion and victimization increased prospective levels of internalizing problems by the end of the school year. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to examine the English phonological skills of English language learners (ELLs) over 5 time points. Method: Sound class accuracy, whole-word accuracy, percentage of occurrence of phonological patterns, and sociolinguistic correlational analyses were investigated in 19 ELLs ranging in age from 5;0 (years; months) to 7;6. Results: Accuracy across all samples was over 90% for all sound classes except fricatives and increased for all sound classes across time. Whole-word accuracy was high and increased across time. With the exception of cluster reduction, stopping, and final consonant deletion, the frequency of occurrence for phonological patterns was less than or equal to 5% at every time point. Sociolinguistic variables such as age of arrival, age of exposure, and age were significantly related to phonological skills. Conclusions: The results were consistent with the hypotheses outlined in Flege's (1995) speech learning model in that the phonological skills of ELLs increased over time and as a function of age of arrival and time. Thus, speech-language pathologists (SLPs) also should expect phonological skills in ELLs to increase over time, as is the case in monolingual children. SLPs can use the longitudinal and connected-speech results of this study to interpret their assessments of the phonological skills of ELLs. [ABSTRACT FROM AUTHOR]

Objective To examine the role of pain experiences in relation to work absence, within the context of other worker health factors and workplace factors among Canadian nurses with work-related musculoskeletal (MSK) injury. Methods Structural equation modeling was used on a sample of 941 employed, female, direct care nurses with at least one day of work absence due to a work-related MSK injury, from the cross-sectional 2005 National Survey of the Work and Health of Nurses. Results The final model suggests that pain severity and pain-related work interference mediate the impact of the following worker health and workplace factors on work absence duration: depression, back problems, age, unionization, workplace physical demands and low job control. The model accounted for 14 % of the variance in work absence duration and 46.6 % of the variance in pain-related work interference. Conclusions Our findings support a key role for pain severity and pain-related work interference in mediating the effects of workplace factors and worker health factors on work absence duration. Future interventions should explore reducing pain-related work interference through addressing workplace issues, such as providing modified work, reducing physical demands, and increasing job control.

Abstract: “Cash-for-Clunkers” was a $3 billion program that attempted to stimulate the U.S. economy and improve the environment by encouraging consumers to retire older vehicles and purchase fuel-efficient new vehicles. We investigate the effects of this program on new vehicle sales and the environment. Using Canada as the control group in a difference-in-differences framework, we find that, of the 0.68 million transactions that occurred under the program, the program increased new vehicle sales only by about 0.37 million during July and August of 2009, implying that approximately 45 percent of the spending went to consumers who would have purchased a new vehicle anyway. Our results cannot reject the hypothesis that there is little or no gain in sales beyond 2009. The program will reduce CO2 emissions by only 9–28.2 million tons based on upper and lower bounds of the estimate of the program effect on sales, implying a cost per ton ranging from $92 to $288 even after accounting for reduced criteria pollutants.

The article offers the author's view on the benefit and harmful effects of the rise of late preterm obstetric intervention in Canada. The author states that controlled trials have shown reduced stillbirth and perinatal mortality risk. The author cites that late preterm delivery raised the number of livebirths within gestational age interval. The author also mentions that the benefit of reducing stillbirth is a logical hypothesis.

Abstract: The causes of the worldwide distribution of Human T-cell Lymphotropic Virus Type 1 (HTLV-1) remain incompletely understood, with competing hypotheses regarding the number and timing of events leading to intercontinental spread on historical and prehistoric timescales. Ongoing discovery of this virus in aboriginal populations of Asia and the Americas has been the main source of evidence for the latter. We conducted molecular phylogenetic and dating analyses for 13 newly reported HTLV-1 strains from Canada. We analyzed two full-length proviral genomes from aboriginal residents of Nunavut (an autonomous territory in Northern Canada including most of the Canadian Arctic), 11 long-terminal-repeat (LTR) sequences from aboriginal residents of British Columbia’s Pacific coast, and 2 LTR sequences from non-aboriginal Canadians. Phylogenetic analysis demonstrated a well-supported affinity between the two Nunavut strains and two East Asian strains, suggesting the presence of an Asian–American sublineage within the widespread “transcontinental” subgroup A clade of HTLV-1 Cosmopolitan subtype a. This putative sublineage was estimated to be 5400–11,900 years in age, consistent with a long-term presence of HTLV-1 in aboriginal populations of the Canadian Arctic. Phylogenetic affinities of the other 11 Canadian HTLV-1 aboriginal strains were diverse, strengthening earlier evidence for multiple incursions of this virus into coastal aboriginal populations of British Columbia. Our results are consistent with the hypothesis of ancient presence of HTLV-1 in aboriginal populations of North America. [Copyright &y& Elsevier]

Adolescents rejected by peers are often targets of bullying. However, peer rejection is not a sure path to victimization. We examined whether characteristics valued by peers (i.e., attractiveness, wealth, academic, and athletic ability) moderated the relationship between peer rejection and victimization. We predicted rejected adolescents high on peer-valued characteristics ( PVCs) would receive fewer nominations for being victimized than adolescents with lower levels. Canadian students in Grades 6-10 ( N = 549; Mage = 13.32, SD = 1.50) provided peer nominations for peer victimization, rejection, attractiveness, wealth, and academic and athletic competence. As hypothesized, each PVC moderated the relationship between peer rejection and peer victimization. No sex differences were found. This study demonstrates the buffering effects of nonbehavioral characteristics valued by peers. [ABSTRACT FROM AUTHOR]

Abstract: The immigrant paradox refers to the contrasting observations that immigrants usually experience similar or better health outcomes than the native-born population despite socioeconomic disadvantage and barriers to health care use. This paradox, however, has not been examined simultaneously in relation to varying degrees of exposure to the receiving society and across multiple outcomes and risk factors. To advance knowledge on these issues, we analysed data of the Maternity Experiences Survey, a nationally representative cross-sectional survey of 6421 Canadian women who delivered singleton infants in 2006–07. We compared the prevalence of adverse pregnancy outcomes and related risk factors according to women''s ethnicity and time since migration to Canada. We calculated prevalences and prevalence ratios (PR) with 95% confidence intervals. Compared to Canadian-born women of European descent, recent immigrants were at lower risk of preterm delivery and morbidity during pregnancy despite having the highest prevalence of low income and low support during pregnancy among all groups, but the paradox was not observed among immigrants with a longer stay in Canada. In contrast, recent immigrants were at higher risk of postpartum depression. Immigrants of non-European origin also had higher prevalence of postpartum depression, irrespective of their length of residence in Canada, but immigrants from European-origin countries did not. Exposure to Canada was also positively associated with higher alcohol and tobacco consumption and body mass index. Canadian-born women of non-European descent were at higher risk of preterm birth and hospitalisation during pregnancy than their European-origin counterparts. Our findings suggest that the healthy migrant hypothesis and the immigrant paradox have limited generalisability. These hypotheses may be better conceptualised as outcome-specific and dependent on immigrants'' ethnicity and length of stay in the receiving country. [Copyright &y& Elsevier]
