Phosphorus removal by substrates in constructed wetland has been widely accepted as the most important way. However, as the substrates of constructed wetland will be saturated with phosphorus adsorption after the long-term treatment of sewage, the effect of phosphorus removal and adsorption by substrates is limited. To improve phosphorus retention ability of substrates and extend the lifetime of full-scale constructed wetland system, this paper systematically summarized the researches of P-saturated substrates regeneration in constructed wetland. And the concern with future research directions encompasses several major topics were also prospected in this paper.

Research on unemployment, underemployment and organisational stress have become major social issues over the past 20 years and have attracted considerable research interest on the part of organisational psychologists both in Australia and overseas. Globalisation has led to restructuring and downsizing in many industrialised societies and a shift, for many workers, from the prospect of secure, long-term employment, to unemployment or inadequate or insecure employment. This paper reviews the research on these topics, discusses their theoretical implications and suggests future research directions.

Sports Concussions

Little is known of the long-term effects of sports-related concussion. Within the scientific literature, conclusions vary substantially where some work suggests there are no long-term consequences at all and other studies show rampant neurodegeneration thought to be caused by sometimes even a single concussive blow to the head. There is growing evidence that supports multiple long-term outcomes, showing both subclinical and clinically relevant changes in the brains of athletes, young and old alike. This article reviews the pathohistology of cerebral concussions and examines the extant literature with a focus on electrophysiological and neuroimaging findings. Neurobehavioral and neurocognitive changes are also reviewed, particularly as they are related to chronic traumatic encephalopathy. Lacunae within the literature are explored, and future research directions are proposed.

Research partnerships between scholars and sport for development and peace (SDP) organizations are common, but firsthand accounts of the challenges and barriers faced by scholars when forming and sustaining partnerships are rare. Therefore, the purpose of this study was to examine them, and to uncover strategies to overcome these challenges across different partnership contexts. Eight prominent SDP scholars were interviewed. Guided by collaboration theory and the partnership literature, findings revealed challenges included navigating the political and organizational landscape; securing commitments from organizations with limited resources; negotiating divergent goals, objectives, and understandings; and conducting long-term evaluations and research. Strategies to address these issues involved developing strategic partnerships, cultivating mutual understanding, building trust, starting small, finding the cause champion, and developing a track record of success. Key theoretical and practical implications are drawn forth, as well as intriguing future research directions.

In the management of human immunodeficiency virus (HIV) infection around the world, chronic complications are becoming a new problem along with the prolonged life expectancy. Chronic pain is widespread in HIV infected patients and even affects those with a low viral load undergoing long-term treatment with antiviral drugs, negatively influencing the adherence to disease management and quality of life. A large proportion of chronic pain is neuropathic pain, which defined as chronic pain caused by nervous system lesions or diseases, presenting a series of nervous system symptoms including both positive and negative signs. Injury caused by HIV protein, central and peripheral sensitization, and side effects of antiretroviral therapy lead to neuroinflammation, which is regarded as a maladaptive mechanism originally serving to promote regeneration and healing, constituting the main mechanism of HIV-related neuropathic pain. Gp120, as HIV envelope protein, has been found to be the major toxin that induces neuropathic pain. Particularly, the microglia, releasing numerous pro-inflammatory substances (such as TNFα, IL-1β, and IL-6), not only sensitize the neurons but also are the center part of the crosstalk bridging the astrocytes and oligodendrocytes together forming the central sensitization during HIV infection, which is not discussed detailly in recent reviews. In the meantime, some NRTIs and PIs exacerbate the neuroinflammation response. In this review, we highlight the importance of clarifying the mechanism of HIV-related neuropathic pain, and discuss about the limitation of the related studies as future research directions.

Metabolites Production

Immunological and metabolic processes are inextricably linked and important for maintaining tissue and organismal health. Manipulation of cellular metabolism could be beneficial to immunity and prevent metabolic and degenerative diseases including obesity, diabetes, and cancer. Maintenance of a normal metabolism depends on symbiotic consortium of gut microbes. Gut microbiota contributes to certain xenobiotic metabolisms and bioactive metabolites production. Gut microbiota-derived metabolites have been shown to be involved in inflammatory activation of macrophages and contribute to metabolic diseases. Recent studies have focused on how nutrients affect immunometabolism. Polyphenols, the secondary metabolites of plants, are presented in many foods and beverages. Several studies have demonstrated the antioxidant and anti-inflammatory properties of polyphenols. Many clinical trials and epidemiological studies have also shown that long-term consumption of polyphenol-rich diet protects against chronic metabolic diseases. It is known that polyphenols can modulate the composition of core gut microbiota and interact with the immunometabolism. In the present article, we review the mechanisms of gut microbiota and its metabolites on immunometabolism, summarize recent findings on how the interaction between microbiota and polyphenol modulates host immunometabolism, and discuss future research directions.

AbstractThe vast majority of traumatic brain injuries (TBI) in children are of mild severity. Even if only a small proportion of children with mild TBI suffer negative outcomes, then mild TBI is a serious public health problem. This review summarizes the literature regarding the neurobehavioral outcomes associated with mild TBI in children and adolescents, focusing on the longstanding debate regarding postconcussive symptoms and attendant conceptual and methodological issues. The review also discusses future research directions, the long-term goal of which is to develop a comprehensive and integrated biopsychosocial model of outcomes that helps guide clinical management.

Grit, which is originally conceptualized as passion and perseverance for long-term goals, has been associated with optimal performance. Although previous meta-analytic and systematic reviews summarized how grit relates to performance outcomes, they possess considerable shortcomings, such as (a) absence of summary on the association of grit with well-being outcomes; (b) absence of discussion on social, psychological, and emotional mechanisms linking grit to well-being; and (c) lack of elaboration on how alternative models can resolve fundamental problems in the grit construct. This integrative review provides a comprehensive summary on the link of grit to performance and well-being outcomes. Importantly, it elaborates how alternative models can potentially address flaws in the existing grit theory. Future research directions are discussed on how to move forward the science of grit.

Evidence from emerging scholarly investigations consistently points to managerial humor as fruitful new grounds to expand management knowledge and practice. In light of this, the present study examined managerial humor as an affective event at work that has short-term emotional and long-term psychological outcomes for employees. To test this empirically, we recruited a sample of 2498 Australian employees to participate in a field experience sampling study. We also considered the potential moderating effect of leader–member exchange on the humor–emotions relationship. Findings provide initial support for managerial humor as an affective event such that when employees perceived their manager’s humor as positive they reported experiencing positive emotions, and vice versa. Importantly, employees with high-quality relationships with their managers responded to their manager’s humor use with a greater number of positive emotions and fewer negative emotions than did employees with low-quality relationships with their managers. We argue that humor is an event that managers must responsibly manage in order to produce positive emotional experiences for employees and support healthy emotion regulation at work. We also discuss the conditions under which it is advisable for managers to use humor with employees, and suggest future research directions to develop this growing field of inquiry.

This study presents an investigation of factors that stimulate the decision-making process of exporting firms from a European Lesser Developed Country (LDC) to continue and sustain export activities. The paper explores the existence of dimensions underlying export motivation and identifies potentially significant differences in perceptions of export stimuli based on firm size, degree of export involvement, and exporting experience. The findings point to a more proactive (than reactive) motivation structure underlying the export activities of these manufacturers. While no relationship is found between perceptions of export motivation and firm size, a number of significant differences in ongoing export stimuli are identified between different groups of firms in terms of export involvement and, to a lesser extent, exporting experience. Managerial and public policy implications are discussed, and suggestions for future research directions are outlined.
