Bringing Carl Rogers Back In: Exploring the Power of Positive Regard at Work

We draw on Carl Rogers’ client‐centred therapy theory and the theoretical lens of positive work relationships to explain why and how positive regard can be a powerful source for the development of employees’ sense of vitality, job performance and organizational citizenship behaviours (OCBs). We theorize that when employees experience relationships characterized by a high level of regard with their co‐workers they are likely to develop a sense of vitality, which in turn results in enhanced job performance and OCBs. These relationships are examined in both experimental and field studies. The results of these multiple studies provide general support for the power of positive regard in augmenting a sense of vitality and enhancing both job performance and citizenship behaviours.     

Who counts and who is counted? Conversations around voting,access, and divisions in the disability community

Online voting platforms have been introduced in some locations as the solution to the many barriers to political participation that disabled people continue to face. Reading the experiences of disabled student voters on university campuses alongside broader trends in electoral reform taking place in jurisdictions across Canada allows us to attend to the dangerous ways in which conversations around access have been limited through virtual solutions that encourage the physical absence of disabled voters. This article situates these absences alongside other categories of exclusion – including groups who are formally disenfranchised – and recalls many unstated values that are active in shaping citizenship cultures. Probing online voting through a critical disability angle, we present a critique of techno-fixes that builds upon broader notions of accessibility and inclusion.     

An investigation into the two‐stage meta‐analytic copula modelling approach for evaluating time‐to‐event surrogate endpoints which comprise of one or more events of interest

Clinical trials of experimental treatments must be designed with primary endpoints that directly measure clinical benefit for patients. In many disease areas, the recognised gold standard primary endpoint can take many years to mature, leading to challenges in the conduct and quality of clinical studies. There is increasing interest in using shorter‐term surrogate endpoints as substitutes for costly long‐term clinical trial endpoints; such surrogates need to be selected according to biological plausibility, as well as the ability to reliably predict the unobserved treatment effect on the long‐term endpoint. A number of statistical methods to evaluate this prediction have been proposed; this paper uses a simulation study to explore one such method in the context of time‐to‐event surrogates for a time‐to‐event true endpoint. This two‐stage meta‐analytic copula method has been extensively studied for time‐to‐event surrogate endpoints with one event of interest, but thus far has not been explored for the assessment of surrogates which have multiple events of interest, such as those incorporating information directly from the true clinical endpoint. We assess the sensitivity of the method to various factors including strength of association between endpoints, the quantity of data available, and the effect of censoring. In particular, we consider scenarios where there exist very little data on which to assess surrogacy. Results show that the two‐stage meta‐analytic copula method performs well under certain circumstances and could be considered useful in practice, but demonstrates limitations that may prevent universal use.     

Specification testing in nonparametric AR‐ARCH models

In this paper, an autoregressive time series model with conditional heteroscedasticity is considered, where both conditional mean and conditional variance function are modeled nonparametrically. Tests for the model assumption of independence of innovations from past time series values are suggested. Tests based on weighted L²‐distances of empirical characteristic functions are considered as well as a Cramér–von Mises‐type test. The asymptotic distributions under the null hypothesis of independence are derived, and the consistency against fixed alternatives is shown. A smooth autoregressive residual bootstrap procedure is suggested, and its performance is shown in a simulation study.     

Benefits of cultural matching in foster care

Sixty-one foster parents from a central Canadian province participated in a telephone interview that included the question: “What are the benefits of fostering children who have the same values, beliefs and traditions as you?” A total of 51 unique responses were obtained and grouped together by 13 foster parents. Multidimensional scaling and cluster analysis were used to analyze the grouping data. Foster parents described five themes: expand on held values, child feels secure, smooth transitions, low stress and more in common. There were similarities and differences between the perspectives of foster parents interviewed and the literature. Implications for future research are discussed.
