Psychological factors related to sport concussion have been overshadowed by interests in neurocognitive recovery. This chapter begins by examining psychological factors relevant to research and management of sport concussion in the context of a culture where normalizing pain and injury is routine. Among the key components of this chapter is a discussion of emotional disturbance following concussion characterized as the “concussion crevice,” which is represented by high fatigue, low vigor, elevated depression and confusion scores, and high overall emotional distress. This differs from pre-injury “iceberg” profiles of high energy, and low depression, fatigue, and confusion, which is characteristic of mentally healthy athletes. Acute emotional response to concussion is distinguished from response to musculoskeletal injury, mirrors neurocognitive recovery, and appears to correspond with the dynamic neurometabolic restoration pattern described in the literature. Directions for future research are recommended.

Abstract Objective Persistent pelvic pain is a complex condition often influenced by psychological factors that can alter treatment outcomes. These factors are potentially modifiable; however, currently there is no instrument to screen for them in these individuals. The purpose of this study was to determine (1) which psychological factors should be screened in individuals with persistent pelvic pain and (2) the most appropriate statements to represent these psychological factors. Methods The study used a focus group design followed by an electronic-Delphi (e-Delphi) process. A focus group consisting of 8 experts was conducted to determine the relevant psychological factors to screen. These results informed round 1 of the e-Delphi process, consisting of a panel of 14 pain/pelvic pain experts. The e-Delphi process consisted of 3 rounds of online surveys and 2 teleconference discussions to establish consensus on the most appropriate statement to screen for each of the psychological factors. Results The focus group identified 13 relevant psychological factors. During the e-Delphi process, relevant screening statements were assessed using a 100-point allocation system. Experts could reword and suggest new statements. Statements were assessed for consensus and stability and were eliminated as the rounds progressed if they met the exclusion criteria. At the termination of round 3, there were 15 statements remaining. Conclusions The final list of 15 statements will assist clinicians in screening for psychological factors and is an important step for clinicians in providing psychologically informed care to people with persistent pelvic pain. Future research should determine the psychometric properties of the statements to determine their clinical utility as a questionnaire. Impact This study has refined a list of statements to help screen for psychological factors in individuals with persistent pelvic pain. Developed robustly using an e-Delphi method, this list is an important first step forward for clinicians to provide psychologically informed care to these individuals.

Amorphous alloys have emerged as important materials for precision machinery, energy conversion, information processing, and aerospace components. This is due to their unique structure and excellent properties, including superior strength, high elasticity, and excellent corrosion resistance, which have attracted the attention of many researchers. However, the size of the amorphous alloy components remains limited, which affects industrial applications. Significant developments in connection with this technology are urgently needed. Laser welding represents an efficient welding method that uses a laser beam with high energy-density for heating. Laser welding has gradually become a research hotspot as a joining method for amorphous alloys due to its fast heating and cooling rates. In this compact review, the current status of research into amorphous-alloy laser welding technology is discussed, the influence of technological parameters and other welding conditions on welding quality is analyzed, and an outlook on future research and development is provided. This paper can serve as a useful reference for both fundamental research and engineering applications in this field.

The purpose of the current paper was to conduct a systematic review of the literature on predictors of emotional distress in caregivers of persons with traumatic brain injury (TBI), and to provide evidence-based classification for prognostic variables to guide future research and clinical practice. A search was conducted using PubMed, CINAHL and PsycINFO databases. The citations of resulting articles were also reviewed. Twenty-eight articles met inclusion criteria and were retained for review. Reviews were conducted in accordance with the 2011 edition of the American Academy of Neurology (AAN) Guidelines for classifying evidence for prognostic studies. Data abstraction revealed one Class I study, four Class II studies, eight Class III studies, and 15 Class IV studies. Results of the review indicated that caregivers’ report of neurobehavioural problems in the person with injury is a probable predictor of emotional distress for caregivers of persons with complicated mild, moderate or severe TBI (Class B evidence). The level of participation in the person with injury, level of support needed by the person with injury, and family systems functioning are probably predictors of emotional distress for caregivers of persons with severe TBI (Class B evidence). Executive functioning impairment in the person with injury, pre-injury emotional distress in caregivers, caregiver age, caregivers’ use of emotion-focused coping, and social support may possibly be risk factors for caregivers’ emotional distress (Class C evidence). Recommendations for future research and implications for assessment and treatment of family caregivers are discussed.

This study was designed to assess the psychological factors influencing life satisfaction of undergraduates. The instruments used were Perceived Stress Scale (PSS), Wong and Law Emotional Intelligence Scale (WLEIS), Rosenberge Self-esteem Scale (RSS), and Satisfaction with Life Scale (SWLS). A total number of 190 participants were purposively selected across various faculties in Ekiti State University. Four hypotheses were tested using Independent t-test to find the effects of perceived stress, emotional intelligence, and self-esteem on life satisfaction. Multiple regression was used to find the joint and individual influences of these variables. The results showed that there is no significant influence of perceived stress on life satisfaction (t (75) = 1.23, p = .22, 95% CI [-1.14, 4.83). There is no significant influence of self-esteem on life satisfaction (t (51) = -1.31, p = .20, 95% CI [-5.28, 1.11), and there is no significant joint influence of perceived stress, emotional intelligence and self-esteem on life satisfaction (F (3,187) = 1.79, p = .15, R2 =.03). Additionally, perceived stress (β = .07, p = .33), emotional intelligence (β = .14, p = 054) and self-esteem (β = .02, p = .83) did not have independent influences on life satisfaction. Implications of the present findings for future research are discussed, as well as potential interventions for improving life satisfaction.

The global construction sector accounts for 13.2% of the world’s gross domestic product (GDP). It not only contributes to the economic growth engine of the world but also climate changes due to its high energy footprint. Sustainable buildings have the potential to reduce the adverse impacts of the construction industry, but their adoption is slow due to hindrances. The aim of this paper is to study literature on barriers to green building adoption to date and highlight the overlapping and unique barriers specific to India in comparison to a few prominent countries, and provide solutions and recommendations for future research. The methodology has been an extensive literature review of the barriers to green building (GB) adoption. The key findings, namely barriers, were classified under economic, governmental, organizational and social perception, information, technology and material categories. Barriers unique to India and a few other developing countries are an extension of project schedules, lack of research and developmental works, lack of public motivation, poor building code enforcement, high payback period, uncertain supply of green materials, improper implementation of policy framework and performance of green building technologies (GBT’s). The GB construction sector is fragmented around the world. Even the GB definition is not the same across the globe although the environmental aspect is the same. Similarly, there are unique and overlapping challenges in GB adoption globally. Buildings in usage perspectives can be classified into residential and non-residential. This study looks only at non-residential GBs due to their homogenous nature. There is a dearth of specific studies related to the adoption of GBs in India. This study aims to fulfil the gap of India’s standing in the barriers to GB adoption with respect to the developed and developing countries. JEL Classification: I18

Lithium Dendrite

Metal lithium anodes, with extremely high specific capacity, low density, and lowest potential, are considered to be the most promising anode materials for next-generation high-energy density batteries. However, in the process of repeated plating and stripping of lithium, lithium dendrites are easily grown on the surface of the metal lithium anode, which greatly reduces the capacity of the battery, even causes hidden safety risks and shortens the battery life. This paper reviews the modification methods of lithium anodes based on the growth process of lithium dendrites, and introduces several current modification methods, including electrolyte additives, artificial SEI and new structure of lithium anodes. Finally, the future research direction and development trend of metal lithium anodes are prospected.
