Self-control exertion and caffeine mouth rinsing: Effects on cycling time-trial performance

ObjectivesThe exertion of self-control has been associated with impaired performance on subsequent physical tasks also requiring self-control. However, the effect in well-trained individuals, and of nutritional intervention strategies to reduce the impact of self-control exertion are unknown. This study, therefore, explored the effect of self-control exertion on endurance performance, and pacing strategies, in well-trained individuals. A further aim was to examine the potential for a caffeine mouth rinse to attenuate any decrements in performance due to self-control exertion.MethodFollowing familiarization, fifteen trained male cyclists completed four simulated 10 km cycling time-trials on a cycle ergometer. Prior to each time-trial, participants completed a congruent Stroop task, or an incongruent Stroop task, to manipulate self-control. They also received either a caffeine (containing 40 mg of dissolved caffeine) or placebo mouth-rinse prior to, and every 2 km during, the cycling time-trial. The participants' performance time, subjective measures (perceived pain, motivation, task importance, and RPE), heart rate, and blood lactate concentration were recorded throughout the time-trials. Data were analysed using three-way (self-control*caffeine*split time) repeated measures ANOVA.ResultsThere was no effect of self-control or caffeine on overall 10 km performance time (all p > 0.05). However, following self-control exertion, split time was significantly slower at 3 km (p = 0.031) and 5 km (p = 0.034), and tended to be slower at 1 km (p = 0.088) and 7 km (p = 0.078). There was no effect of the caffeine mouth rinse, nor did this interact with self-control, to affect split times (all p > 0.05). Prior self-control exertion and a caffeine mouth rinse did not influence perceptions of pain, motivation, and task importance in well-trained individuals (all p > 0.05).ConclusionsFindings suggest that prior self-control exertion affects self-regulatory pacing strategies during the first 7 km of a 10 km cycling time-trial, in well-trained individuals. However, caffeine mouth rinsing does not attenuate the effects of self-control exertion on subsequent endurance performance.     

Counteracting performativity in schools: the case for laughter as a qualitative and redemptive indicator

The auditing culture and its concomitant, ‘performativity’, have been at the core of the on‐going public sector reforms of the last twenty‐five years or so. The advantages and limitations of performance indicators as a managerial technique of control have long been known. Considered from an organisational, social and political perspective, it is now possible to evaluate the predictions made in the 1980s and 1990s. These focused on the consequences for the cultures of educational institutions and the emotional resilience of individuals – especially the children – within them, if techniques of this kind are inappropriately managed and emphasise the impersonal and quantitative. The article offers a compromise solution that balances effectiveness with humanity and spirituality, in the form of a radical performance indicator, namely, laughter.     

Population Health and Trauma‐Informed Practice: Implications for Programs,Systems, and Policies

Population studies indicate that trauma exposure is ubiquitous and has a significant impact on health. Trauma‐informed practice seeks to address the health consequences of trauma through integrative responses that incorporate an understanding of the effects of trauma, the multiple pathways to recovery, and the potential for re‐traumatization. Current trauma‐informed practice considers trauma exposure an individual clinical problem rather than a societal problem with population health consequences. Population health refers to the aggregated health status of individuals who share some characteristic, such as trauma exposure, and includes the study of determinants that shape the distribution of health outcomes in specific populations. In this paper, we describe a population health perspective for trauma‐informed practice that complements the current clinical perspective, and then discuss implications of that perspective for programs, systems, and policies. We summarize essential concepts about trauma over the life course and describe principles of population health science relevant to trauma‐informed practice. We then discuss implications of these principles by identifying four priorities for trauma‐informed practice from a population health perspective: (a) adopting trauma‐informed policies to prevent trauma exposure and to foster resilience in the aftermath of trauma; (b) infusing trauma‐informed practice into everyday activities so it is a routine part of interpersonal transactions; (c) incorporating trauma‐informed practices into existing service systems; and (d) adapting existing treatments to incorporate trauma‐informed principles for population health impact.     

Exploring Community Mobilization in Northern Quebec: Motivators,Challenges, and Resilience in Action

Nunavimmiut (people of the land) are the Indigenous peoples of the northern peninsula of the province of Quebec. Communities of Nunavik and its regional organizations have been making concerted efforts in implementing community‐based strategies to support family wellbeing. These community strategies are grounded in many of the values underpinning community psychology: favoring empowerment‐oriented approaches, fostering community capacity, and transforming organizational cultures to allow for new modes of interaction, as well as new policies and practices that are grounded in community and culture. Despite the growing support and expectation for community mobilization, there is still very little research on the processes and challenges to such mobilization. In this study, we explored the unique challenges and facilitators to community endeavors in northern Quebec in order to better understand the complex dynamics and the strengths that Inuit build upon. We first used a focused ethnographic approach in the context of a 5‐year community mobilization project in Nunavik. We then conducted 12 individual interviews and two small group interviews with Inuit working on community‐based wellbeing‐oriented mobilization projects in four additional communities. Results expose how sociogeographical realities and colonialism influence the process of community mobilization. They also highlight the values and motivational factors that lead community members to move beyond these influences.

The effect of motivation and positive affect on ego depletion: Replenishment versus release mechanism

In this study, 2 experiments were conducted to investigate whether motivation and positive affect can alleviate ego depletion and to elucidate their possible mechanisms. In Experiment 1, a crossing‐out‐letter task was adapted to reach an ego depletion state for Chinese participants. Participants were then randomly assigned to the extrinsic motivation group, the positive affect group or the depletion control group. After the experimental treatment, a dumbbell task was used to measure participants' remaining self‐regulatory resources. The results showed that participants in the motivation and positive affect groups performed better on the dumbbell task than participants in the depletion control group. Experiment 2 was similar to Experiment 1 except that participants were asked to perform an additional unexpected dumbbell task after a neutral video following the above procedure. The results of Experiment 1 were replicated; however, participants' performance on the additional dumbbell task differed. The positive affect group performed better than the depletion control group, indicating an increase in self‐regulatory resources and thus supporting the replenishment effect of positive affect. No significant difference was found between the motivation group and the depletion control group.     

Withdrawal From Coparenting Interactions During Early Infancy

This study examines early withdrawal in the coparenting system, and the utility of a brief problem‐solving discussion about coparenting responsibilities as a means for evaluating such withdrawal. One hundred and fifteen couples were evaluated both prenatally and at 3 months postpartum. During prenatal assessments, parents rated their personalities and completed marital assessments. After the baby arrived, they completed a negotiation task in which they discussed disputes about parenting roles and responsibilities, and interacted together with the baby in a triadic play assessment. Fathers' but not mothers' withdrawal during coparenting negotiations was associated with greater disengagement and less warmth during triadic play and with fathers' feelings that mothers did not respect their parenting. Fathers' but not mothers' withdrawal during coparenting negotiations was also forecast by low ego resilience and by an increase in depressive symptomatology during the postpartum. As the negotiation task appeared to be an effective provocateur of withdrawal when confronting coparenting disagreement, it may prove useful for eliciting this aspect of coparental process in work with couples.     

Community Resilience as a Metaphor, Theory, Set of Capacities, and Strategy for Disaster Readiness

Communities have the potential to function effectively and adapt successfully in the aftermath of disasters. Drawing upon literatures in several disciplines, we present a theory of resilience that encompasses contemporary understandings of stress, adaptation, wellness, and resource dynamics. Community resilience is a process linking a network of adaptive capacities (resources with dynamic attributes) to adaptation after a disturbance or adversity. Community adaptation is manifest in population wellness, defined as high and non-disparate levels of mental and behavioral health, functioning, and quality of life. Community resilience emerges from four primary sets of adaptive capacities--Economic Development, Social Capital, Information and Communication, and Community Competence--that together provide a strategy for disaster readiness. To build collective resilience, communities must reduce risk and resource inequities, engage local people in mitigation, create organizational linkages, boost and protect social supports, and plan for not having a plan, which requires flexibility, decision-making skills, and trusted sources of information that function in the face of unknowns.     

The ego, the Other and the primal fact

Japan has absorbed many western ideas since the late nineteenth century, but Japanese philosophers have often been reluctant to accept the western idea of the “I” in its entirety. The I transgresses to the Other more easily than western philosophies think and imports what belongs to the Other as his own. How is this possible? Husserl attempted to explain the constitution of the Other by the intentionality that goes from the I to the Other, mediated by the body. However, Husserl later discovered that the constitution of both the I and the Other is more of a two-way movement. This double-movement is essential for all constitutions and departs from a deep (primal) dimension that is not yet egological. Even in the self-reflection of the I, a similar double-movement between the primal and egological dimensions can be seen. The I is supported, but at the same time threatened, by this movement.
