Infant and toddler responses to a redesign of their childcare outdoor play space

Researchers used an affordances-based conceptual framework to study infants' and toddlers' responses to the redesign of their play space. Behavior mapping and child tracking observations showed that the introduction of features such as edging, levels and inclines appeared to increase the level and variety of children's physical activity, and lead to greater utilization of the space. While researchers observed children engaging with natural affordances, this was less than expected, possibly due to educator constraints. Children's engagement with new features indicated unique child views of the space and a delight in challenge. Findings suggest the value of looking for children's perspective on affordances, and considering the effects of specific features and the influence of caregivers in evaluating design outcomes.

Rethinking the univariate approach to panel unit root testing: using covariates to resolve the incidental trend problem

In an influential article, Hansen showed that covariate augmentation can lead to substantial power gains when compared to univariate tests. In this article, we ask if this result extends also to the panel data context? The answer turns out to be yes, which is maybe not that surprising. What is surprising, however, is the extent of the power gain, which is shown to more than outweigh the well-known power loss in the presence of incidental trends. That is, the covariates have an order effect on the neighborhood around unity for which local asymptotic power is negligible.

Do venture capitalists play a monitoring role in an emerging market? Evidence from the pay–performance relationship of Chinese entrepreneurial firms

This paper investigates venture capitalists' monitoring of managerial behavior by examining their impact on CEO pay–performance sensitivity across various controlling structures in Chinese firms. We find that the effectiveness of venture capitalists' monitoring depends on different types of agency conflict. In particular, we find that venture capital (VC) monitoring is hampered in firms that experience severe controlling-minority agency problems caused by disproportionate ownership structures. We provide further evidence that VC is more likely to exert close monitoring in firms that have greater managerial agency conflict, and thus require more direct monitoring. However, controlling-minority agency problems have a greater impact on VC monitoring than managerial agency problems. Overall, our study suggests that venture capitalists' monitoring role is hampered in an emerging market where firms have complex ownership structures that contribute to severe agency conflict between controlling and minority shareholders.

Treating children with psychosis: an integrative play therapy approach

Children affected by psychosis often endure unresolved mental health and psychosocial disturbances that impede social, academic, and behavioral functioning (Algon, Yi, Calkins, Kohler, & Borgmann-Winter, 2012). This article provides clinicians with a discussion of play therapy and empirically informed techniques to improve treatment outcomes for children diagnosed with psychosis. The literature review comprises various aspects of this unique pediatric population, including prevalence, assessment/evaluation, symptoms, and psychosocial treatment. Additionally, an integrative play therapy approach is highlighted, comprising (a) family interventions (McFarlane, Dixon, Lukens, & Lucksted, 2003), (b) psychosocial approaches (Green & Drewes, 2013; Stewart & Green, 2015), and (c) school-based support (Flanagan, Allen, & Henry, 2010). The article concludes with a case study depicting the psychological challenges a typical child with psychosis encounters and the associated treatment options available to play therapy practitioners from an integrative standpoint.

Regulators of mitochondrial complex I activity: a review of literature and evaluation in postmortem prefrontal cortex from patients with bipolar disorder

Phenomenologically, bipolar disorder (BD) is characterized by biphasic increases and decreases in energy. As this is a state-related phenomenon, identifying regulators responsible for this phasic dysregulation has the potential to uncover key elements in the pathophysiology of BD. Given the evidence suggesting mitochondrial complex I dysfunction in BD, we aimed to identify the main regulators of complex I in BD by reviewing the literature and using the published microarray data to examine their gene expression profiles. We also validated protein expression levels of the main complex I regulators by immunohistochemistry. Upon reviewing the literature, we found PARK-7, STAT-3, SIRT-3 and IMP-2 play an important role in regulating complex I activity. Published microarray studies however revealed no significant direction of regulation of STAT-3, SIRT-3, and IMP-2, but a trend towards downregulation of PARK-7 was observed in BD. Immunocontent of DJ-1 (PARK-7-encoded protein) were not elevated in post mortem prefrontal cortex from patients with BD. We also found a trend towards upregulation of DJ-1 expression with age. Our results suggest that DJ-1 is not significantly altered in BD subjects, however further studies are needed to examine DJ-1 expression levels in a cohort of older patients with BD.

Institutional investors in Australia: do they play a homogenous monitoring role?

This paper examines whether the presence of institutional investors in Australian publicly listed firms has an impact on firm performance. Our findings provide evidence that institutional investors are not a homogenous group of investors and that it is important to distinguish them by investment objective and their monitoring ability to exert influence. Results show that while institutional investors taken as a homogenous group appear to play an important governance role in terms of future firm performance, our analyses of the three broad typologies of institutional investors and by their respective sub-categories reveal differing conclusions. While pressure-resistant institutional investors (i.e., independent and having only investment relationship) significantly improve the short-term performance of Australian listed firms, they do not show any long-term monitoring ability. The impact of pressure-sensitive institutional investors is less clear, which is consistent with the view that these investors have some existing and potential business ties with the investee firms. More interestingly, we find that "faceless" investors via nominee and trustee institutions play an important monitoring role in creating a long-term firm value. Results have policy implications on the monitoring abilities of institutional investors in Australia.

Assumptions of decision-making capacity: the role supporter attitudes play in the realisation of Article 12 for people with severe or profound intellectual disability

The United Nations Convention on the Rights of Persons with Disabilities (UNCRPD) was the first legally binding instrument explicitly focused on how human rights apply to people with disability. Amongst their obligations, consistent with the social model of disability, the Convention requires signatory nations to recognise that “…persons with disabilities enjoy legal capacity on an equal basis with others in all aspects of life” and mandates signatory nations to develop “…appropriate measures to provide access by persons with disability to the support they may require in exercising their legal capacity”. The Convention promotes supported decision-making as one such measure. Although Australia ratified the UNCRPD in 2008, it retains an interpretative declaration in relation to Article 12 (2, 3, 4), allowing for the use of substituted decision-making in situations where a person is assessed as having no or limited decision-making capacity. Such an outcome is common for people with severe or profound intellectual disability because the assessments they are subjected to are focused on their cognition and generally fail to take into account the interdependent nature of human decision-making. This paper argues that Australia’s interpretative declaration is not in the spirit of the Convention nor the social model of disability on which it is based. It starts from the premise that the intention of Article 12 is to be inclusive of all signatory nations’ citizens, including those with severe or profound cognitive disability. From this premise, arises a practical need to understand how supported decision-making can be used with this group. Drawing from evidence from an empirical study with five people with severe or profound intellectual disability, this paper provides a rare glimpse on what supported decision-making can look like for people with severe or profound intellectual disability. Additionally, it describes the importance of supporters having positive assumptions of decision-making capacity as a factor affecting supported decision-making. This commentary aims to give a focus for practice and policy efforts for ensuring people with severe or profound cognitive disability receive appropriate support in decision-making, a clear obligation of signatory nations of the UNCRPD. A focus on changing supporter attitudes rather than placing the onus of change on people with disability is consistent with the social model of disability, a key driver of the UNCRPD.
