Isotopes content, mineralogical composition, Uranium and Thorium contents and determined activity ratios from METEOR cruise M74/3 in 2007

Authigenic carbonate deposits have been sampled with the remotely operated vehicle 'MARUM-QUEST 4000 m' from five methane seeps between 731 and 1823 m water depth along the convergent Makran continental margin, offshore Pakistan (northern Arabian Sea). Two seeps on the upper slope are located within the oxygen minimum zone (OMZ; ca. 100 to 1100 m water depth), the other sites are situated in oxygenated water below the OMZ (below 1100 m water depth). The carbonate deposits vary with regard to their spatial extent, sedimentary fabrics, and associated seep fauna: Within the OMZ, carbonates are spatially restricted and associated with microbial mats, whereas in the oxygenated zone below the OMZ extensive carbonate crusts are exposed on the seafloor with abundant metazoans (bathymodiolin mussels, tube worms, galatheid crabs). Aragonite and Mg-calcite are the dominant carbonate minerals, forming common early diagenetic microcrystalline cement and clotted to radial-fibrous cement. The delta18O carbonate values range from 1.3 to 4.2 per mil V-PDB, indicating carbonate precipitation at ambient bottom-water temperature in shallow sediment depth. Extremely low delta13Ccarbonate values (as low - 54.6per mil V-PDB) point to anaerobic oxidation of methane (AOM) as trigger for carbonate precipitation, with biogenic methane as dominant carbon source. Prevalence of biogenic methane in the seepage gas is corroborated by delta13C methane values ranging from - 70.3 to - 66.7per mil V-PDB, and also by back-calculations considering delta 13C methane values of carbonate and incorporated lipid biomarkers.

Attachment, psychological functioning, and resilience within the street involved youth populations: describing youth who access community agency support

Youth homelessness is defined within the literature as youth who have left their homes and are living independent of parental figures and/or caregivers, have no stable residence or source of income, and lack access to the supports needed to make the challenging transition into adulthood (Canadian Observatory on Homelessness, 2015). Previous research studying homeless (or street-involved) youth has primarily focused on risk factors hindering the development of this population, and has largely ignored resilience, coping, and help-seeking behaviours. The current study examined the attachment styles (both categorically and dimensionally), psychological functioning, resilience, and help-seeking behaviours in street-involved youth of St. John’s, Newfoundland. Face-to face interviews were completed over a four-month period with 63 youth (42 males, 21 females) aged 15-29 (Mage = 20.00), recruited from a local community organization providing outreach services to street-involved youth. Results revealed the disproportionate struggles of the street-involved youth population, and highlighted higher levels of attachment insecurity, psychological distress and lower resilience compared to normative peers. Findings also showed a significant difference in psychological functioning, overall resilience, and emotional reactivity based on individual attachment style. In an exploratory model of help-seeking, a positive relationship was found between overall resilience (defined as a sense of mastery and sense of relatedness) and frequency of community service access. However, contrary to predictions, no relationships were found between frequency of community service access and attachment, psychological functioning, or emotional reactivity. Implications of the present findings in development of interventions for street-involved youth are discussed, in addition to strengths and limitations of the present research, and suggested areas of future inquiry.

Microbialites and lipid biomarker from coral reefs off the volcanic islands Tahiti and Vanuatu and from the nonvolcanic sites Belize and the Maldives

The occurrence of microbialites in post-glacial coral reefs has been interpreted to reflect an ecosystem response to environmental change. The greater thickness of microbialites in reefs with a volcanic hinterland compared to thinner microbial crusts in reefs with a non-volcanic hinterland led to the suggestion that fertilization of the reefal environment by chemical weathering of volcanic rocks stimulated primary productivity and microbialite formation. Using a molecular and isotopic approach on reef-microbialites from Tahiti (Pacific Ocean), it was recently shown that sulfate-reducing bacteria favored the formation of microbial carbonates. To test if similar mechanisms induced microbialite formation in other reefs as well, the Tahitian microbialites are compared with similar microbialites from coral reefs off Vanuatu (Pacific Ocean), Belize (Caribbean Sea, Atlantic Ocean), and the Maldives (Indian Ocean) in this study. The selected study sites cover a wide range of geological settings, reflecting variable input and composition of detritus. The new lipid biomarker data and stable sulfur isotope results confirm that sulfate-reducing bacteria played an intrinsic role in the precipitation of microbial carbonate at all study sites, irrespective of the geological setting. Abundant biomarkers indicative of sulfate reducers include a variety of terminally-branched and mid chain-branched fatty acids as well as mono-O-alkyl glycerol ethers. Isotope evidence for bacterial sulfate reduction is represented by low d34S values of pyrite (-43 to -42 per mill) enclosed in the microbialites and, compared to seawater sulfate, slightly elevated d34S and d18O values of carbonate-associated sulfate (21.9 to 22.2 per mill and 11.3 to 12.4 per mill, respectively). Microbialite formation took place in anoxic micro-environments, which presumably developed through the fertilization of the reef environment and the resultant accumulation of organic matter including bacterial extracellular polymeric substances (EPS), coral mucus, and marine snow in cavities within the coral framework. ToF-SIMS analysis reveals that the dark layers of laminated microbialites are enriched in carbohydrates, which are common constituents of EPS and coral mucus. These results support the hypothesis that bacterial degradation of EPS and coral mucus within microbial mats favored carbonate precipitation. Because reefal microbialites formed by similar processes in very different geological settings, this comparative study suggests that a volcanic hinterland is not required for microbialite growth. Yet, detrital input derived from the weathering of volcanic rocks appears to be a natural fertilizer, being conductive for the growth of microbial mats, which fosters the development of particularly abundant and thick microbial crusts.

Examining the Relationship Between Passion and Perceptions of Cohesion in Athletes

The purpose of the present study was to examine the relationship of harmonious and obsessive passion to perceptions of task and social cohesion in team sport athletes. Participants were 370 competitive (N=252) and recreational (N=118) athletes ranging from 18- to 28-years-old (Mage=20.20, SD=1.52) from a wide variety of team sports. Participants completed the Passion Scale (Vallerand et al., 2003) and the Group Environment Questionnaire (Carron et al., 1985). A MANOVA revealed that competitive athletes were more passionate and had higher perceptions of cohesion than did recreational athletes. Multiple regression analyses revealed a positive relationship between both harmonious and obsessive passion and both task (ATG-T, GI-T) and social (ATG-S, GI-S) cohesion. Theoretical and practical implications are discussed pertaining to the importance of harmonious and obsessive passion in athletes and perceptions of cohesion in competitive and recreational sport.

The Social Environment in Children’s Sport: Cohesion, Social Acceptance, Commitment, and Enjoyment

The primary purpose of the current study was to determine whether perceptions of cohesion mediated the relationship between social acceptance and individual commitment and enjoyment in children’s sport. A secondary purpose involved the assessment of the temporal nature of cohesion over the course of an athletic season. A total of 209 (Mage = 9.87 years; SD = 1.34) recreational soccer players completed questionnaires at three time points (T1 – social acceptance, cohesion; T2 – cohesion; T3 – commitment, enjoyment, cohesion) during an athletic season. Using structural equation modeling, the results indicated that task cohesion mediated the relationship between social acceptance and commitment and enjoyment, whereas social cohesion did not. In addition, individual perceptions of cohesion did not vary significantly over the course of the season. These results will be discussed in terms of their theoretical and practical implications. As one example, the relative stability in terms of perceptions of cohesion in this population could inform future intervention work aimed at enriching the social environment

Just Need Some Satisfaction: Examining the Relationship between Passion for Exercise and the Basic Psychological Needs

Individuals often pursue activities for which they are passionate about, and this passion is operationalized as being harmonious (an autonomous desireto engage in the activity) or obsessive (a controlled desire to engage in the activity) in nature (Vallerand et al., 2003). With regard to harmonious passion, Vallerand et al. (2003) suggests that it is fostered in environments that nurture innate needs for autonomy, competence, and relatedness. The purpose of the present study was to explore the nature of the passion-basic psychological needs (competence, autonomy, relatedness) relationship. Kinesiology students (N = 917; Mage = 18.54 SD = 1.66) completed the Passion Scale (Vallerand et al., 2003) and the Psychological Need Satisfaction in Exercise Scale (Wilson et al., 2006). Results from the SEM path analysis indicated that harmonious passion was positively related to competence (SPE = .43) and relatedness (SPE = .43) and obsessive passion was negatively related to autonomy (SPE = -.18)(CFI = .90, RMSEA = .07, SRMR = .07). Implications for exercise participation/enjoyment are discussed.

Athlete Perceptions of Intra-Group Conflict in Sport Teams

The study of conflict has been of primary interest in various fields such as organisational psychology for decades (e.g. Barki & Hartwick, 2004). In sport psychology, however, conflict research has been almost nonexistent (Lavoi, 2007) with few exceptions (e.g. Holt et al., 2012; Sullivan & Feltz, 2001). The importance of understanding conflict in sport and in groups, however, has been acknowledged because it has potentially serious implications for group outcomes (Lavoi, 2007). The present study investigated competitive sport athletes’ perceptions of intra-group conflict in sport. Ten intercollegiate athletes: (N=5 males, N=5 females; Mage=25.00, SD=2.87) participated in semi-structured interviews. Athletes perceived the nature of conflict to manifest itself in several ways including: (a) disagreements; (b) negative emotions; and (c) interference/antagonistic behaviors. In addition, conflict episodes were perceived to arise in task and social situations. The findings are discussed in terms of their contributions to current perspectives on intra-group conflict in sport.

Youth sport coaches’ reflections on leadership behaviours during games and practices

Youth sport coaches shape the developmental sporting experience for their athletes (Camiré, Trudel, & Forneris, 2014). Specifically, coaches who form individualized, supportive relationships with their athletes can increase the development of personal and social skills (Fraser-Thomas, Côté, & Deakin, 2005). In light of the value of these relationships, increasing evidence is prompting the application of leadership theories, such as Transformational Leadership (TFL), in youth sport (Vella et al., 2013). The aim of this study was to explore coach perceptions of how and why leadership behaviours are applied in the youth sport context. Eleven coaches (Mage= 42.3, SD= 15.2) were recruited from competitive youth soccer and volleyball clubs (athletes’ Mage= 15.8, SD= 1.9) in Eastern Ontario and participated in a stimulated recall interview. During the interviews, coaches reflected upon their own coaching behaviours and provided insight into the application of leadership behaviours in youth sport. Responses were prompted by relevant video sequences from recorded practice and game sessions. A thematic content analysis revealed that; i) coaches use a variety of leadership behaviours in youth sport, ii) the use of leadership behaviours vary across sport contexts or settings, and iii) contrasting leadership styles (e.g., transactional vs. transformational) are associated with distinctive coach objectives (e.g., promoting confidence vs. establishing respect). These findings have helped identify gaps within coach education, and provide theoretical insight for applying leadership theories, and more specifically TFL, to help improve the sport experiences of young athletes.

Bodies in Nature: Associations between Exposure to Nature, Connectedness to Nature, and Body Image

Here, we sought to replicate previous work showing a relationship between connectedness to nature and body appreciation, and extend it by examining associations between exposure to natural environments and other body image-related variables. An online sample of 399 U.S. women and men (Mage = 34.55 years) completed measures of body appreciation, connectedness to nature, nature exposure, appearance investment, sociocultural attitudes toward appearance, and self-esteem. Path analysis showed that nature exposure and connectedness to nature, respectively, were associated with body appreciation in women and men, both directly and indirectly via self-esteem. Connectedness to nature also mediated the link between nature exposure and body appreciation. In men, but not women, the link between connectedness to nature and body appreciation was also mediated by appearance investment and internalisation of a muscular ideal. These results may point to novel methods for promoting more positive body image in adults through engagement with nature.

Predicting Muscularity-Related Behavior, Emotions, and Cognitions in Men: The Role of Psychological Need Thwarting, Drive for Muscularity, and Mesomorphic Internalization

We examine the relationships that internalization, need thwarting (NT), and drive for muscularity (DFM), along with their interactions, had with weightlifting, muscle dissatisfaction (MD), and muscle-related-worry (MRW). A sample of 552 men (MAGE = 20.5 years, SD = 3.1) completed the Psychological Need Thwarting Scale, the Internalization subscale of the male version of the Sociocultural Attitudes Towards Appearance Questionnaire, the Drive for Muscularity Scale-Attitudes subscale, the Male Body Attitudes Scale-Muscularity subscale, the Body Change Inventory-Worry subscale, and an inventory assessing weightlifting behavior. DFM significantly predicted weightlifting, MRW, and MD. Internalization significantly predicted weightlifting and MRW. NT significantly predicted weightlifting and MD, and its relationship with MRW approached significance. The interaction terms did not predict weightlifting or MRW. The NT/DFM and NT/Internalization interaction terms predicted MD. These results highlight the role of NT in predicting appearance variables in men.
