Full Text Available Educators are increasingly aware that the efficacy of social and emotional learning (SEL is dependent on implementation factors, not just program content. These include the philosophy underpinning an intervention, the beliefs as well as the skills of facilitators, and the classroom/whole school context in which the intervention takes place. This article outlines the philosophy and pedagogy of Circle Solutions and presents findings from research where 18 undergraduate students supported and developed ‘Circle Time’ in 8 Greater Western Sydney primary schools for a university module on community service. The study indicates that when there is full teacher participation within the principles of the Circle philosophy, together with activeschool support that promotes relational values, the learning outcomes for positive relationship building are more sustainable.

Full Text Available A series of studies investigated a proposed new individual difference characteristic or trait, facility for sustained positive affect, consisting of tendencies that allow individuals to maintain a high level of positive mood. Exploratory and confirmatory factor analyses resulted in the creation of a measure, the self-congruent and new activities (SANA scale which identified two core aspects of sustainable positive affect, engaging in self-congruent activities and engaging in new activities. A higher level of facility for sustainable affect, as operationalized by the SANA scale, was associated with maintenance of positive mood for a month, fewer symptoms of depression and anxiety, less negative affect, and more life satisfaction, relationship satisfaction, work satisfaction, mindfulness, personal expansion and growth, and emotional intelligence. The results provided initial evidence that facility to maintain positive affect may be an emotion-related individual difference characteristic.

Full Text Available There’s no escape: we are always in relationship. Being aware of this matters. Doing something to build constructive relationships for sustainability, matters even more. This paper considers the connection between good relationships and effective sustainability work in local government. It draws on the collective experiences of four practitioners who have worked over many years in, with or for local government and argues that a good deal of project success is contingent upon the development of positive relationships with stakeholders, contractors, communities, businesses, colleagues, partners and other agencies and agency officers. Relationships can help or hinder project process, progress and outcomes. This paper identifies some approaches for building quality relationships and uses examples to highlight these strategies. These include: recognising that developing and maintaining resilient relationships and high quality communication is a critical foundation for success; designing projects with explicit relationship outcomes; and allocating time, money and other resources to support the development of effective relationships.
Full Text Available Sustainability is one of the most important challenges of our time. Companies are integrating sustainability in their marketing, communication and their actions. Sustainability has more recently also been linked to project management. The logic behind this link is that sustainability needs change and projects are realizing change. Several studies explored how the concept of sustainability impact project management. The research project reported in this paper elaborates on these works by studying how sustainability affects project success. Project managers, logically, strive for project success and considering sustainability may influence this success. Based upon a review of relevant literature, the paper develops a conceptual model that provides a more detailed understanding of how considering different dimensions of sustainability may affect the individual criteria of project success. The study also provides a conceptual mapping of the different relationships between dimensions of sustainability and criteria of project success. This mapping shows that the most positive relationships are expected for the relationship between sustainability and the success criteria stakeholder satisfaction, future readiness and controlled project execution. The expected relationship between considering sustainability and completing the project on schedule and within budget is uncertain.

This article investigates the evolution of sustainability positioning in residential property marketing to shed light on the specific role and responsibility of housebuilders and housing investors in urban development. To this end, an analysis is made of housing advertisements published in Basel, Switzerland, over a period of more than 100 years. The paper demonstrates how to draw successfully on advertisements to discern sustainability patterns in housing, using criteria situated along the dimensions building, location and people. Cluster analysis allows five clusters of sustainability positioning to be described—namely, good location, green building, comfort living, pre-sustainability and sustainability. Investor and builder types are differently located in these clusters. Location emerges as an issue which, to a large extent, is advertised independently from other sustainability issues.

The construct of positive family relationships (PFR), defined as family members getting along well and supporting each other, was investigated in a long-term prospective study. A newly constructed scale of positive family relationships developed using the nominal response model of item-response theory, was subject to a longitudinal network of relations analysis. The conceptualization for this research was founded on a positive psychology framework. Data derived from the Fullerton Longitudinal Study and spanned 20 years from middle childhood (age 9 years) to early adulthood (age 29 years). Evidence indicated both stability and change in PFR across time. Moderate to high stability of individual differences among families across 9 annual assessments was found from ages 9-17 years. Concomitantly across these years, there was a progressive decline in PFR. PFR proved to be independent of socioeconomic status. Specific conceptually based directional hypotheses were tested using structural equation modeling. Multiple sources of information included intra- and cross-informant, as well as objective and ecologically valid data. The network of relations involved concurrent and predictive criterion-related variables. PFR had a pervasive relation to a variety of psychological domains across time. As predicted, PFR related (a) positively to family cohesion and inversely to family conflict, (b) positively to parental social support, (c) positively to children's self-concept, (d) positively to children's academic performance and educational attainment, and (e) inversely to children's behavior problems. The theoretical importance of the findings and the applicability of the PFR Scale for both researchers and practitioners in the field of family psychology are discussed.

Music sometimes improves performance in sustained attention tasks. But the type of music employed in previous investigations has varied considerably, which can account for equivocal results. Progress has been hampered by lack of a systematic database of music varying in key characteristics like tempo and valence. The aims of this study were to establish a database of popular music varying along the dimensions of tempo and valence and to examine the impact of music varying along these dimensions on restoring attentional resources following performance of a sustained attention to response task (SART) vigil. Sixty-nine participants rated popular musical selections that varied in valence and tempo to establish a database of four musical types: fast tempo positive valence, fast tempo negative valence, slow tempo positive valence, and slow tempo negative valence. A second group of 89 participants performed two blocks of the SART task interspersed with either no break or a rest break consisting of 1 of the 4 types of music or silence. Presenting positive valence music (particularly of slow tempo) during an intermission between two successive blocks of the SART significantly decreased miss rates relative to negative valence music or silence. Results support an attentional restoration theory of the impact of music on sustained attention, rather than arousal theory and demonstrate a means of restoring sustained attention. Further, the results establish the validity of a music database that will facilitate further investigations of the impact of music on performance.

Nucleosomes compact and regulate access to DNA in the nucleus, and are composed of approximately 147 bases of DNA wrapped around a histone octamer1, 2. Here we report a genome-wide nucleosome positioning analysis of Arabidopsis thaliana utilizing massively parallel sequencing of mononucleosomes. By combining this data with profiles of DNA methylation at single base resolution, we identified ten base periodicities in the DNA methylation status of nucleosome-bound DNA and found that nucleosomal DNA was more highly methylated than flanking DNA. These results suggest that nucleosome positioning strongly influences DNA methylation patterning throughout the genome and that DNA methyltransferases preferentially target nucleosome-bound DNA. We also observed similar trends in human nucleosomal DNA suggesting that the relationships between nucleosomes and DNA methyltransferases are conserved. Finally, as has been observed in animals, nucleosomes were highly enriched on exons, and preferentially positioned at intron-exon and exon-intron boundaries. RNA Pol II was also enriched on exons relative to introns, consistent with the hypothesis that nucleosome positioning regulates Pol II processivity. DNA methylation is enriched on exons, consistent with the targeting of DNA methylation to nucleosomes, and suggesting a role for DNA methylation in exon definition. PMID:20512117

The social interactions of task groups were investigated for their influences on member moods. Initially, participants' received an induction of positive, negative, or neutral moods via listening to music that continued throughout the experimental session. Moods were measured after the induction. Students then made decisions on four choice dilemmas alone or as members of a four-person group. Subsequently, positive and negative moods were again measured. Positive moods of participants who worked with other group members on the task were sustained, but diminished for those working alone. Negative moods of participants working in groups diminished over time, but were sustained for those working individually. These results were interpreted in the context of motivational systems theory of group involvement (Park & Hinsz, 2006). Additionally, although there was a tendency for member moods to homogenize over assessments, this did not reach significance. Results document the affective benefits that often accompany task group interaction suggesting that group interaction has features of positive mood induction. This report highlights the need to consider social influences on affect in task settings so that group dynamics, processes, and behaviors can be better understood.
Full Text Available Chewing is crushing food not only to aid swallowing and digestion, but also to help stress relief and regulate cognitive function, especially in attention. It is well known that chewing gum is used for sleepiness prevention during work, learning, and driving, suggesting a link between chewing and sustained attention. We hypothesized that chewing elevates attention and/or alertness, leading to improvements in cognitive performance. We carried out a systematic review of the PubMed database. We inspected the attributes of effects on attention in studies investigating the effects of chewing on attention or alertness conducted with pre-post design in healthy subjects, except elderly. We identified 151 references, 22 of which were included: 14 (64% showed positive attributes of effects on attention, 1 (5% showed negative attributes of effects on attention, 5 (23% showed both positive and negative attributes of effects on attention, and 2 (9% showed no significant attributes of effects on attention. Thus, positive attributes of effects of chewing on attention, especially on sustained attention, were shown in over half of the reports. These effects also appeared with improvement in mood and stress relief and were influenced by time-on-task effect. Further studies are needed, but chewing could be useful for modifying cognitive function.

The neural mechanisms underlying hunger are poorly understood. AgRP neurons are activated by energy deficit and promote voracious food consumption, suggesting these cells may supply the fundamental hunger drive that motivates feeding. However recent in vivo recording experiments revealed that AgRP neurons are inhibited within seconds by the sensory detection of food, raising the question of how these cells can promote feeding at all. Here we resolve this paradox by showing that brief optogenetic stimulation of AgRP neurons before food availability promotes intense appetitive and consummatory behaviors that persist for tens of minutes in the absence of continued AgRP neuron activation. We show that these sustained behavioral responses are mediated by a long-lasting potentiation of the rewarding properties of food and that AgRP neuron activity is positively reinforcing. These findings reveal that hunger neurons drive feeding by transmitting a positive valence signal that triggers a stable transition between behavioral states.
Full Text Available Orientation: Companies are under ever-increasing pressure from both internal and external stakeholders to consider the environmental and social impacts of their operations and to mitigate these impacts. This necessitates an investigation into the effect of sustainability initiatives on the financial performance (FP of a company.Research purpose: The study analysed the relationship between sustainability performance and FP in South African listed companies.Motivation for the study: Some South African listed companies acknowledge in their sustainability reports that there is a link between sustainability development and long-term shareholder value. This implies that FP is linked to sustainable development performance. This relationship has not been researched for South African listed companies and therefore needs to be investigated.Research design, approach and method: A similar research method was used as for an international study. Forty-five listed South African companies were selected as the sample. Their sustainable development reports were used for analysis. Data were analysed with the use of content and a canonical correlation analysis.Main findings: The results of the study revealed that an overall positive relationship exists between sustainability performance and FP. Practical implications: South African companies that have a high involvement and focus on specific sustainable development initiatives that are integrated into overall sustainable development strategy can deliver improved FP for the organisation and deliver long-term value to its shareholders.Contribution: Six sustainable development aspects were found to be significantly correlated with improved FP and if incorporated into a company’s sustainable development strategy can lead to increased successes.

Boredom is a common experience, prevalent in neurological and psychiatric populations, yet its cognitive characteristics remain poorly understood. We explored the relationship between boredom proneness, sustained attention and adult symptoms of attention deficit hyperactivity disorder (ADHD). The results showed that high boredom-prone individuals (HBP) performed poorly on measures of sustained attention and showed increased symptoms of ADHD and depression. The results also showed that HBP individuals can be characterised as either apathetic-in which the individual is unconcerned with his/her environment, or as agitated-in which the individual is motivated to engage in meaningful activities, although attempts to do so fail to satisfy. Apathetic boredom proneness was associated with attention lapses, whereas agitated boredom proneness was associated with decreased sensitivity to errors of sustained attention, and increased symptoms of adult ADHD. Our results suggest there is a complex relationship between attention and boredom proneness.

A source of light in the vacuum ultraviolet (VUV) spectral region includes a reflective UV-sensitive photocathode supported in spaced parallel relationship with a mesh electrode within a rare gas at low pressure. A high positive potential applied to the mesh electrode creates an electric field which causes drifting of free electrons occurring between the electrodes and producing continuous VUV light output by electric field-driven scintillation amplification sustained by positive photon feedback mediated by photoemission from the photocathode. In one embodiment the lamp emits a narrow-band continuum peaked at 175 nm.

Full Text Available This study investigated perspectives on literacy as a tool for sustainable relationship among people. The study was conducted due to the significant role of literacy as an instrument of empowerment to improve relationship with other people by sharing information, ideas and knowledge to meet variety of purposes. The study adopted descriptive research design of the survey type. A sample of 1675 respondents that comprised of 1032 literates and 643 illiterates was selected through purposive and simple random sampling techniques from two local government areas of Ekiti state, Nigeria. An instrument tagged ‘Perception of Literacy for Social Relationship Questionnaire (PLHLSRQ’ was used to collect data from the respondents. The instrument was validated by experts and tested for reliability at 0.71 coefficients through test-re-test method. Data collected were statistically analysed using mean, standard deviation and student t-test at 0.05 level of significance. The result of the study showed a significant difference between literates and illiterates’ perspectives on literacy as a tool for sustainable social relationship. The study also revealed significant gender difference in perspectives on literacy for sustainable social relationship. Based on the findings, it was recommended among others that government should organise more awareness and sensitization programmes and seminars to purposefully attract illiterate commercial drivers and riders to literacy programmes.

Air-to-air refueling, formation flying, and projectile countermeasures all rely on a pilot's ability to be aware of his position and motion relative to another object. Eight subjects participated in the study, all members of the sustained acceleration stress panel at Wright-Patterson AFB, OH. The task consisted of the subject performing a two-dimensional join up task between a KC-135 tanker and an F-16. The objective was to guide the nose of the F-16 to the posterior end of the boom extended from the tanker, and hold this position for 2 s. If the F-16 went past the tanker, or misaligned with the tanker, it would be recorded as an error. These tasks were performed during four G(z) acceleration profiles starting from a baseline acceleration of 1.5 G(z). The plateaus were 3, 5, and 7 G(z). The final acceleration exposure was a simulated aerial combat maneuver (SACM). One subject was an outlier and therefore omitted from analysis. The mean capture time and percent error data were recorded and compared separately. There was a significant difference in error percentage change from baseline among the G(z) profiles, but not capture time. Mean errors were approximately 15% higher in the 7 G profile and 10% higher during the SACM. This experiment suggests that the ability to accurately perceive the motion of objects relative to other objects is impeded at acceleration levels of 7 G(z) or higher.

Full Text Available Nigeria as nation has over the years engaged in lots of developmental activities without actions which makes achievements to elude the people. Development of societies doesn’t happen in the vacuum. Thus, the adoption of Structural Adjustment Program, SAP, by Nigeria leading to the neglect of the custom periodic National Plan at a time when Nigeria had no structure for development was the beginning of journey to widened inequality and large poverty incidence, depth and severity. To close the gap between the rich and the poor, the Nigeria government had designed and implemented some programs and policies whose implementation has not solved the inherent problems. In year 2000, the world leaders subscribed to the Millennium Development Goals to ensure synergized global approach to solving the poverty menace. Programs designed in Nigeria to achieve the MDGs focused on the urban centers thereby relegating the rural areas which are responsible for the feeding of the teeming population of the urban dwellers. Farming households and the general rural communities do not have access to clean water, quality education and health facilities, good feeder roads, affordable and safe energy as well as other socioeconomic and socio-infrastructural facilities that would ensure sustainable living for the people whose contribution to the national economy cannot be overemphasized. This study therefore looks at the structural actions the Nigeria government should embarked upon to ensure that the rural dweller have access to life. As the government would be developing programs and policies to achieve the Sustainable Development Goals whose priority is the end poverty in all forms and everywhere by 2030, this study reveals how to position the rural economy for developmental attention from the policy makers.

This study has been motivated by two developments. Firstly, by the vast literature on the relationship between inflation and growth which is abundantly endowed with diverse theoretical explanations and contradictory evidence and by the unique experience of the Turkish economy with inflation and growth. A preliminary examination of the Turkish data pointed to a negative relation between inflation and growth. Moreover, there is a unanimous agreement among the students of the Turkish economy that many factors have contributed to inflation in this country. In view of these facts this paper employs a VAR model which will enable us to identify the sources of the shocks and control for external factors. In addition VAR models have a high predictive power and enable the researcher to observe the impulse response functions. The study employs Generalised Impulse Response analysis. In the empirical experiments oil prices, money supply, government spending and taxes have been taken as the most likely determinants of inflation. The study shows that there is a negative relationship between inflation and output growth in Turkey and that the underlying explanatory factor is the real exchange rate. This result is robust.
Full Text Available A major challenge facing many countries around the world is how to sustainably address the issues of increased numbers of refugee migrants. The refugee migrant “issue” is often heavily political as a high density of migrants in local areas impacts communities (e.g., disrupting local employment, service and culture. Different migrants come with different “baggage” and needs which can be a significant draw on the hosting communities’ resources. This paper argues that sustainable long-term solutions to refugee migrants will require a rethink to the existing dominant models of containment and charity. The paper draws upon insights from a study of a large refugee camp in Jordan over a three-and-a-half-year period, and historical cases of refugee migration. The paper presents a sustainable model that develops long-term capability for the various stakeholder groups.
Full Text Available Instrumental arguments linking inequality to environmental sustainability often suppose a negative relationship between inequality and social cohesion. While social cohesion is difficult to measure, there are measures of a narrower concept, social trust, and empirical studies have shown that social trust is negatively related to inequality. In this paper we test whether at least part of the observed relationship may be explained by income level, rather than income distribution. We use individual response data from the World Values Survey at the income decile level, and find evidence that income level is indeed important in explaining differences in levels of social trust, but it is insufficient to explain all of the dependence. In the sample used for the study, we find that both income level and income distribution help explain differences in social trust between countries.

Inattentional blindness, whereby observers fail to detect unexpected stimuli, has been robustly demonstrated in a range of situations. Originally research focused primarily on how stimulus characteristics and task demands affect inattentional blindness, but increasingly studies are exploring the influence of observer characteristics on the detection of unexpected stimuli. It has been proposed that individual differences in working memory capacity predict inattentional blindness, on the assumption that higher working memory capacity confers greater attentional capacity for processing unexpected stimuli. Unfortunately, empirical investigations of the association between inattentional blindness and working memory capacity have produced conflicting findings. To help clarify this relationship, we examined the relationship between inattentional blindness and working memory capacity in two samples (Ns = 195, 147) of young adults. We used three common variants of sustained inattentional blindness tasks, systematically manipulating the salience of the unexpected stimulus and primary task practice. Working memory capacity, measured by automated operation span (both Experiments 1 & 2) and N-back (Experiment 1 only) tasks, did not predict detection of the unexpected stimulus in any of the inattentional blindness tasks tested. Together with previous research, this undermines claims that there is a robust relationship between inattentional blindness and working memory capacity. Rather, it appears that any relationship between inattentional blindness and working memory is either too small to have practical significance or is moderated by other factors and consequently varies with attributes such as the sample characteristics within a given study.

Moving from largely command and control measures in the 1970s and 1980s, through cleaner production initiatives and self-regulatory initiatives in the 1990s, the emphasis is increasingly on using networks and partnerships between private firms, NGOs, government and civil society as levers...... companies and public bodies have increased. Hence, the tools and means employed—outside as well as inside the network—have developed accordingly. In this paper, a distinct partnership mode of government–business relationships - a collaborative network with respect, trust and mutual legitimacy - is discussed...... and related to the Green Network way of doing things. The conclusion is that through dialogue, reflexivity and the establishment of an enabling environment, public–private partnerships can become useful vehicles in societies’ move towards sustainability....

Full Text Available Background A growing set of studies has shown a positive relationship between aerobic fitness and a broad array of cognitive functions. However, few studies have focused on sustained attention, which has been considered a fundamental cognitive process that underlies most everyday activities. The purpose of this study was to investigate the role of aerobic fitness as a key factor in sustained attention capacities in young adults. Methods Forty-four young adults (18–23 years were divided into two groups as a function of the level of aerobic fitness (high-fit and low-fit. Participants completed the Psychomotor Vigilance Task (PVT and an oddball task where they had to detect infrequent targets presented among frequent non-targets. Results The analysis of variance (ANOVA showed faster responses for the high-fit group than for the low-fit group in the PVT, replicating previous accounts. In the oddball task, the high-fit group maintained their accuracy (ACC rate of target detection over time, while the low-fit group suffered a significant decline of response ACC throughout the task. Discussion Importantly, the results show that the greater sustained attention capacity of high-fit young adults is not specific to a reaction time (RT sustained attention task like the PVT, but it is also evident in an ACC oddball task. In sum, the present findings point to the important role of aerobic fitness on sustained attention capacities in young adults.

The purpose of this study was to test whether positive automatic cognitions moderated the relationship between event stressfulness and meaning in life. Measures of these constructs were administered to 232 students and community-dwelling adults. Supporting hypotheses and the literature, positive automatic cognitions moderated the relationship between event stressfulness and meaning in life. For persons with high levels of positive thinking, greater event stressfulness was associated with higher meaning in life. For persons with low levels of positive thinking, greater event stressfulness was associated with lower meaning in life. These results were obtained when controlling for positive affect, as well as the positive affect × event stressfulness interaction.

Full Text Available According to several studies, power and interdependence play a considerable role in understanding the buyer–supplier relationships, yet, empirical research is still limited. Also, the nature of the buyer-supplier relationship and managing them might vary based on the power position of buyers and suppliers. Few studies focused on the reason behind this interrelation and strong influence of power on the buyer-supplier relationships. Thus, the purpose of this study is to gain better understanding and try to identify how power position and buyer-supplier relationships are interrelated, and whether there are common determinants and/or characteristics behind this strong bond between the two concepts. Both transaction cost analysis theory and social exchange theory were integrated in building the argument. Regarding the methodology, qualitative exploratory research design was employed by using multiple-case study as the main research method, where three multinational Egyptian organizations were selected. Moreover, data was collected using individual in-depth interviews, and analyzed through coding and cross case analysis techniques. The results showed that there are common factors that influence both buyer-supplier relationship characteristics and power position attributes. And according, the findings helped in pointing out a new lens of discussing and investigating the bond between buyer-supplier relationships ad power in research.

Full Text Available The aim of this study was to investigate the relationship between the disclosure of sustainability with some features of corporate governance in publicly traded Brazilian firms. The characteristics of corporate governance studied were duality of CEO, level corporate governance, sustainability committee, independent directors, influences of the community, board interlocking and family management. The analysis was based in a sample of the 76 companies listed in IBRX-100 BM&FBovespa that were followed during the period 2009-2011. The technique of content analysis was used in corporate reports, financial statements and reports and social sustainability of the firms investigated in order to measure the level of disclosure of sustainability. The panel data model with fixed and random effects was used to assess the relationship between the disclosure of sustainability with the characteristics of the corporate governance of the companies investigated. The results show that the family administration, the age of the company, the influence of community, sustainability committee, the size and performance have positive effect on the disclosure of sustainability. However, participation in New Market (NM corporate governance of BM&FBovespa was negatively related to the level of sustainability disclosure, demonstrating that the insertion at this level differentiated corporate governance does not seem to influence the disclosure by enterprises investigated.

Appreciation is a key component of subjective well-being and may contribute to positive mental health. Few studies have examined relationships between specific aspects of appreciation and the 3 dimensions of positive mental health, and thus, the aim of this study was to identify associations between aspects of appreciation and positive mental health. Appreciation and positive mental health were measured in 266 Korean university students (50% females) using the Appreciation Inventory and the Mental Health Continuum-Short Form. The results obtained showed that Have Focus significantly predicted Emotional Well-being; Have Focus and Loss/Adversity significantly predicted Social Well-being and Have Focus, Expression and Nature/Daily Life significantly predicted Psychological Well-being. The implications of results that might enable positive mental health to be enhanced are discussed. © 2015 International Union of Psychological Science.

The relationship between biodiversity and ecosystem productivity has been explored in detail in herbaceous vegetation, but patterns in forests are far less well understood. Liang et al. have amassed a global forest data set from >770,000 sample plots in 44 countries. A positive and consistent relationship can be discerned between tree diversity and ecosystem productivity at landscape, country, and ecoregion scales. On average, a 10% loss in biodiversity leads to a 3% loss in productivity. This means that the economic value of maintaining biodiversity for the sake of global forest productivity is more than fivefold greater than global conservation costs.

In the first part of this study, the position assumed by a normal wrist during unconstrained maximal grip and the relationship between wrist position and grip strength were investigated in 20 healthy subjects. Grip strength and wrist position were recorded in the self-selected position and then again while the subjects voluntarily deviated the wrist randomly into flexion, extension, or radial or ulnar deviation of 10 to 15 degrees. The self-selected position was 35 degrees of extension and 7 degrees of ulnar deviation. Grip strength was significantly less in any position of deviation from this self-selected position, even after accounting for fatigue. With the wrist in only 15 degrees of extension or in neutral radio-ulnar deviation, grip strength was reduced to two thirds to three fourths of normal. Sex did not affect wrist position. The dominant wrists were within 5 degrees of the nondominant ones but were relatively less extended and in more ulnar deviation. Grip strength is significantly reduced when wrist position deviates from this self-selected optimum position. In the second part of the study, the effect of grasp size on this self-selected position was studied in 21 subjects. The degree of wrist extension was inversely and linearly related to how large a setting on the Jamar dynamometer was used. This was true regardless of hand size, although the effect was more significant for smaller hands. Radial and ulnar deviations were not affected by handle position. A minimum of 25 degrees of wrist extension was required for optimum grip strength.(ABSTRACT TRUNCATED AT 250 WORDS)

Full Text Available With the increasing of labor salaries, the RMB exchange rate, resource product prices and requirements of environmental protection, inexpensive labor and land are no longer the decisive factor of regional competitiveness. From this perspective, China needs to shift from the extensive development mode to the sustainable development mode. Science and technology resources rational allocation is one of the key issues in sustainable development. Based on the counties (districts data of Zhejiang Province in China, this paper portrays the spatial variation of regional sustainable development level of this area. This paper finds that counties tend to cluster in groups with the same sustainable development level, and this agglomeration trend has been enforced during the past several years. It then testifies to the relationship between the allocation of science and technology resources and local sustainable development, identifies science and technology human resources, financial resources and environmental resource are positively related to local sustainable development, except government financial support. The economic level has a negative relationship with regional sustainable development. This is because the development of the Zhejiang economy grown at the expense of the environment and ecosystem. Some advice is given according to the empirical analysis result.

The United Nations predicts that by 2050 nearly three fourths of the world's population will live in urban areas, including cities. People are attracted to cities because these urban areas offer diverse opportunities, including the availability of goods and services and a higher quality of life. Cities, however, may not be sustainable with this population boom. To address sustainability, urban developers and engineers are building green structures, and businesses are creating products that are safe for the environment. Additionally, efforts are needed to place human health at the core of urban sustainability. Without human health, cities will not survive for future generations. Nursing is the discipline that can place human health in this position. Nursing's initiatives throughout history are efforts of sustainability-improving human health within the physical, economic, and social environments. Therefore, nursing must take a leadership role to ensure that human health is at the core of urban sustainability.

One of the most studied macroecological patterns is the interspecific abundance-occupancy relationship, which relates species distribution and abundance across space. Interspecific relationships between temporal distribution and abundance, however, remain largely unexplored. Using data for a natural assemblage of tabanid flies measured daily during spring and summer in Nova Scotia, we found that temporal occurrence (proportion of sampling dates in which a species occurred in an experimental trap) was positively related to temporal mean abundance (number of individuals collected for a species during the study period divided by the total number of sampling dates). Moreover, two models that often describe spatial abundance-occupancy relationships well, the He-Gaston and negative binomial models, explained a high amount of the variation in our temporal data. As for the spatial abundance-occupancy relationship, the (temporal) aggregation parameter, k, emerged as an important component of the hereby named interspecific temporal abundance-occurrence relationship. This may be another case in which a macroecological pattern shows similarities across space and time, and it deserves further research because it may improve our ability to forecast colonization dynamics and biological impacts.

The purpose of this study was to evaluate the relationship between the position of mesiodens and its complications. The subjects for this study consisted of 172 patients with mesiodens. Panoramic radiographs and cross-sectional tomography were taken of all of the subjects. Their clinical records and radiographs were analyzed in order to study the direction and vertical and sagittal position of mesiodens, as well as complications caused by mesiodens. The number of mesiodens was one in 112 cases (65.1%) and two in 60 cases (34.9%). Complications were found in 121 mesiodentes (52.2%), with being median diastema the most frequent. The incidence of complications was high in erupted mesiodens (75.0%), in horizontal mesiodens (89.8%) and in mesiodens located within the arch (75.7%), but was low in mesiodens impacted above apex (29.8%), in normal position (34.4%) and in palatally positioned mesiodens (46.5%). It was suggested that the frequency of complications was different according to the vertical position, the direction of the crown and the sagittal position.

Full Text Available This study was designed to explore whether children's representations of attachment contribute to the co-construction of positive teacher–child relationships. An assessment of verbal intelligence was included as a predictor on the assumption that teachers might perceive themselves as having better relationships with more verbally competent children. Participants were 52 children from two pre-schools, in the district of Lisbon. The Attachment Story Completion Task (ASCT was used to assess children's attachment security. The PCV-P (a scale developed in portuguese language was used to describe teacher–child relationships through teachers' ratings of child secure base behavior and emotion regulation and the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-R was used to access verbal skills. Bivariate correlations showed that the teachers' rating of child secure base behavior was significantly associated with both child attachment security and verbal IQ. In a multiple regression analysis, the overall model R2 was significant, as was the interaction term showing a moderating effect of attachment security on the relation between verbal IQ and teachers' ratings of secure base. The results suggest that co-construction of a close attachment-relevant relationship with teachers in early childhood is, in part, a function of the security in the context of parent-child attachment, but also of child verbal development.

Full Text Available Workforce sustainability is of vital utmost importance for the viability and competitive advantage of contemporary organizations. Therefore, and in parallel with the rise of positive organizational psychology, organizations have become increasingly interested in how to enhance their employees’ positive psychological well being. In this paper, amplition interventions – i.e. interventions aimed at enhancing positive work-related well being - are presented as a valuable tool to increase workforce sustainability. In the past decade, some work-related interventions focused on amplition have been developed and tested for their effectiveness. In this paper, we will first outline some important preconditions for successful interventions and briefly discuss the intervention process itself. Next, we will give an overview of empirical work on amplition interventions, focusing on interventions that are aimed at enhancing employee work engagement. Future research should focus on testing the effects of these type of interventions on outcomes at the team and organizational level.
Full Text Available Despite the importance of the human/social dimension of organizational sustainability, this area of scholastic endeavor has received relatively little attention when compared to the economic and environmental dimensions of sustainability. On the basis of social exchange theory, this study posited the important role that employee work engagement is a key component for improving human performance for organizational sustainability. In order to do so, it suggests the important role that employee work engagement has on the relationships among various factors in the organization, including organizational procedural justice, knowledge sharing, and innovative work behaviors. A total of 400 complete responses from full-time employees in Korean organizations were used for the purpose of data analysis with structural equation modeling (SEM. The results demonstrated that organizational procedural justice is positively related with employee work engagement, knowledge sharing, and innovative work behavior. In addition, work engagement enhances employee knowledge sharing and innovative work behavior, and knowledge sharing enhances innovative work behavior. With regard to the mechanisms of these relationships, work engagement and knowledge sharing acted as significant mediators. Based on the findings, we suggested relevant research implications and recommendations for future research on sustainable organizations.

Given the pressures on land to produce ever more food, doing it 'sustainably' is growing in importance. However, 'sustainable agriculture' is complex to define, not least because agriculture impacts in many different ways and it is not clear how different aspects of sustainability may be in synergy or trade off against each other. We conducted a meta-analysis to assess the relationships between multiple measures of sustainability using novel analytical methods, based around defining the efficiency frontier in the relationship between variables, as well as using correlation analysis. We define 20 grouped variables of agriculture's impact (e.g. on soil, greenhouse gas, water, biodiversity) and find evidence of both strong positive and negative correlations between them. Analysis based on the efficiency frontier suggests that trade-offs can be 'softened' by exploiting the natural between-study variation that arises from a combination of farming best practice and context. Nonetheless, the literature provides strong evidence of the relationship between yields and the negative externalities created by farming across a range of measures. © 2016 Cambridge Philosophical Society.

Nature sounds are increasingly used by some food retailers to enhance in-store ambiance and potentially even influence sustainable food choices. An in-store, 2 × 3 between-subject full factorial experiment conducted on 627 customers over 12 days tested whether nature sound directly and indirectly influenced willingness to buy (WTB) sustainable foods. The results show that nature sounds positively and directly influence WTB organic foods in groups of customers (men) that have relatively low initial intentions to buy. Indirectly, we did not find support for the effect of nature sound on influencing mood or connectedness to nature (CtN). However, we show that information on the product's sustainability characteristics moderates the relationship between CtN and WTB in certain groups. Namely, when CtN is high, sustainability information positively moderated WTB both organic and climate friendly foods in men. Conversely, when CtN was low, men expressed lower WTB organic and climate friendly foods than identical, albeit conventionally labelled products. Consequently, our study concludes that nature sounds might be an effective, yet subtle in-store tool to use on groups of consumers who might otherwise respond negatively to more overt forms of sustainable food information.

This contribution deals with the concept of healthy organizations and starts with a definition of healthy organizations and healthy business. In healthy organizations, culture, climate, and practices create an environment conducive to employee health and safety as well as organizational effectiveness (Lowe, 2010). A healthy organization thus leads to a healthy and successful business (De Smet et al., 2007; Grawitch and Ballard, 2016), underlining the strong link between organizational profitability and workers' well-being. Starting from a positive perspective focused on success and excellence, the contribution describes how positive organizational health psychology evolved from occupational health psychology to positive occupational health psychology stressing the importance of a primary preventive approach. The focus is not on deficiency and failure but on a positive organizational attitude that proposes interventions at different levels: individual, group, organization, and inter-organization. Healthy organizations need to find the right balance between their particular situation, sector, and culture, highlighting the importance of well-being and sustainability. This contribution discusses also the sustainability of work-life projects and the meaning of work in healthy organizations, stressing the importance of recognizing, respecting, and using the meaning of work as a key for growth and success. Finally, the contribution discusses new research and intervention opportunities for healthy organizations.

Full Text Available The relationship between protected areas and forest management has been one that has often been fraught with conflict. New practices in the forest sector and new ecological insights have led more recently to better co-operation in some regions, although it is debatable to what extent cooperative approaches are desirable. In this introduction to the special section on the relationships between protected areas and sustainable forest management, we outline the history of the forestry and protected areas sectors in Canada, and the evolution of the relationships between them. We define key terms for the debate and offer a novel framework for understanding the relationship between the two sectors as management regimes that occur along parallel continua of sustainability. This framework is contrasted against real-world findings from across Canada, and with examples from elsewhere in the world.

The increasing impetus to provide an effective response to childhood obesity has generated a corresponding concern that weight management interventions may lead to emotional problems among young people, notably in relation to the development of a negative body image. However, currently the processes and factors that contribute to the acquisition of body image among young people is poorly understood. Drawing on salutogenic theory, this paper employs an assets-based approach that focuses on health promoting and protective factors to identify how young people may create or sustain positive body images. Secondary data analysis was undertaken from the WHO Health Behaviour in School Aged Children Study. During the spring term of 2002, information was collected from 6425 English adolescents aged 11-15 using a self-administered questionnaire. The data were analysed using stepwise multinomial logistic regression to determine which factors were associated with positive body image; a total of 2898 students were included in the final analysis. Adolescents who self-identified as having a positive body image were more likely to report ease of talking with a father figure, feeling intelligent, perceiving that their family were well off and a belief that their teachers were interested in them as people. Body Mass Index, age, gender and living within a household containing a father were also significant predictors of body image. The discussion provides an exploration of how the construction of young people's emotional health is in part linked with the attainment of a secure and positive body image. The implications for health promotion and educational programmes are then examined. By considering the assets, which support or sustain a positive body image during adolescence, obesity prevention programmes could be better tailored to meet the needs of young people. In the future, a salutogenic curriculum might provide an alternative to unsustainable levels of deficit led, targeted

Full Text Available Protection and sustainable forest management are related but unique, with protection focusing on minimising risk to ecosystems and sustainable management emphasising economic development. Given these distinct roles, a defining characteristic of the relationship between the two approaches is their relative abundance and distribution. The relationship is currently imbalanced, with only 12% of Canada allocated to protection, indicating that ecological values have historically been traded off in favour of resource production. The intactness of Canada′s boreal forest provides an opportunity for a more holistic approach that conserves its globally significant environmental attributes while also supporting resource production. The Boreal Forest Conservation Framework proposes a balanced relationship that allocates land approximately equally between protection and sustainable management. It is a framework that has been endorsed by industry, Aboriginal, and conservation organisations, and is supported by conservation science. Recent commitments to comprehensive land-use planning at regional scales are consistent with the collaborative approach promoted by the Boreal Forest Conservation Framework, and suggest that conservation objectives are likely to receive increased attention in Canada′s boreal region relative to recent history. Ensuring that land-use planning is proactive and balanced will be essential to forging a cooperative relationship between sustainable management and protection in the region.

Little is known about long-distance dating relationships. This study aimed to investigate differences between long-distance dating relationships and geographically close relationships and to explore predictors of relationship quality. Participants were 474 women and 243 men in long-distance dating relationships and 314 women and 111 men in geographically close relationships. Few differences existed between long-distance dating relationships and geographically close relationships, while individual and relationship characteristics predicted relationship quality. These results indicate that individuals in long-distance dating relationships are not at a disadvantage and that relationship and individual characteristics predict relationship quality. This knowledge could be a powerful tool for helping those in long-distance dating relationships.

Eighty-nine high school seniors were administered a questionnaire that gathered information on their exercise habits (ranging from rarely to daily), relationships with parents and peers, depressive tendencies, sports involvement, drug use, and academic performance. Students with a high level of exercise had better relationships with their parents (including greater intimacy and more frequent touching), were less depressed, spent more time involved in sports, used drugs less frequently, and had higher grade point averages than did students with a low level of exercise.

Children thrive in inclusive settings where each child is an important part of the community. When differences are celebrated and similarities discovered, children learn to value themselves, appreciate their peers, and develop meaningful and significant relationships with one another. A sizable body of research indicates that promoting positive…

The broaden-and-build theory of positive emotions suggests that positive emotions can widen the range of potential coping strategies that come to mind and subsequently enhance one's resilience against stress. Studies have shown that high stress, especially chronic levels of stress, strongly contributes to the development of anxiety and depressive symptoms. However, researchers have also found that individuals who possess high levels of resilience are protected from stress and thus report lower levels of anxiety and depressive symptoms. Using a sample of 200 postdoctoral research fellows, the present study examined if (a) positive emotions were associated with greater resilience, (b) coping strategies mediated the link between positive emotions and resilience and (c) resilience moderated the influence of stress on trait anxiety and depressive symptoms. Results support the broaden-and-build theory in that positive emotions may enhance resilience directly as well as indirectly through the mediating role of coping strategies-particularly via adaptive coping. Resilience also moderated the association of stress with trait anxiety and depressive symptoms. Although stress is unavoidable and its influences on anxiety and depressive symptoms are undeniable, the likelihood of postdocs developing anxiety or depressive symptoms may be reduced by implementing programmes designed to increase positive emotions, adaptive coping strategies and resilience.

To examine the cross-sectional association between overweight and obesity and positive and negative affect. Participants included 273 women, aged 29-84 years, who were enrolled in the Geelong Osteoporosis Study (GOS). Weight and height were measured and overweight and obesity determined from body mass index (BMI; kg/m(2)) according to WHO criteria. Medical history and lifestyle exposures were assessed by questionnaire. Positive and negative affect scores were derived using the validated 20-item Positive and Negative Affect Schedule (PANAS) and categorised into tertiles. A pattern of greater negative affect scores was observed for increasing levels of BMI. Setting normal weight as the referent category, the odds for having a negative affect score in the highest tertile were sequentially increased for women who were overweight (OR = 1.31, 95% CI: 0.72-2.40) and obese (OR = 1.95, 95% CI: 1.02-3.73). The association between obesity and increased negative affect was diminished by adjusting for physical illness (adjusted OR = 1.76, 95% CI: 0.91-3.42). These associations were not substantially influenced by positive affect score or other exposures. No association was detected between BMI categories and positive affect scores. We report data suggesting that obesity is associated with greater negative affect scores, reflecting emotions such as distress, anger, disgust, fear and shame, and that this association is attenuated by physical illness. Further investigations are now warranted to explore possible mechanistic interplay between pathological, neurobiological and psychosocial factors.

Full Text Available The aim of this study was to identify the variables that influence the firms inclusion in the BM&FBOVESPA Corporate Sustainability Index (CSI, and if such membership is correlated with the firm market value in the Brazilian market. We collected annual data of firms for the period 2006 to 2011. The methodology included the use of methods such as regression analysis type logit and panel data models. The results showed that companies that have joined the ISE have characteristics distinct from those who did not opt for membership. Firms with larger size, higher profitability and sectors considered high environmental impact are more likely to be classified in the ISE. When examined whether inclusion in the CSI has relation with the metric firm value, the results did not reject the hypothesis of positive relationship, even during the financial crisis of 2008, however, found evidence of a negative relationship in the post-crisis period.

Research into the methodological development of alternative systems of sustainability measures is recent. In understanding sustainable development in a multi-dimensional sense, one of the most significant advances was the construction of Synthetic Indexes, applicable to different spatial spheres or to organisations, businesses, institutions, etc. The Spanish port system of general interest comprises 46 ports integrated in 28 Port Authorities, which in 2014 moved 482,000,000t of goods and more than 28 million passengers. This gives an idea of its importance for the Spanish economy. Using a derivation of the procedure used to calculate the Port Sustainability Synthetic Index, in this research the analysis of the relationship that exists between the findings obtained for the economic and environmental dimensions is used. This enables the existence of links between ports and economic and environmental indicators for a sample of 16 Port Authorities of Spain to be verified. Copyright © 2016 Elsevier Ltd.

This study examines to what extent corporations use sustainability control systems (SCS) to translate proactive sustainability strategy into corporate sustainability performance. The study investigates the mediating effect of SCS on the relationship between proactive sustainability strategy and corporate sustainability performance. Survey data were collected from top managers in 175 multinational and local corporations operating in Sri Lanka and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). SCS were observed to only partially mediate the relationship between proactive sustainability strategy and corporate sustainability performance. The mediating effect of SCS is further examined under three sustainability strategies; environmental and social strategies reveal a partial mediation, while the economic strategy exhibits no mediation. The study also finds that (i) a proactive sustainability strategy is positively associated with SCS and corporate sustainability performance and (ii) SCS are positively associated with corporate sustainability performance.

Full Text Available Alternaria brown spot, or ABS (Alternaria alternata, is the most prevalent fungal disease of tangerines in the world. Field observations have revealed ABS lesions on leaves wounded by the citrus leaf miner (CLM. Thus, the objective of this study was to assess the relationship between CLM and ABS. Leaves from young Murcott tangor plants and detached leaves from 16 different varieties of tangerines with and without lesions caused by CLM were inoculated with A. alternata. The symptoms of the plants were subsequently quantified by counting the number of lesions, and the lesion area was estimated using a diagrammatic scale. The presence of CLM damage aggravates the severity of Alternaria alternata fungus infections in susceptible tangerine varieties.

Pentastomids are a small group of vermiform animals with unique morphology and parasitic lifestyle. They are generally recognized as being related to the Arthropoda; however, the nature of this relationship is controversial. We have determined the complete sequence of the mitochondrial DNA (mtDNA) of the pentastomid Armillifer armillatus and complete or nearly complete mtDNA sequences from representatives of four previously unsampled groups of Crustacea: Remipedia (Speleonectes tulumensis), Cephalocarida (Hutchinsoniella macracantha), Cirripedia (Pollicipes polymerus) and Branchiura (Argulus americanus). Analyses of the mtDNA gene arrangements and sequences determined in this study indicate unambiguously that pentastomids are a group of modified crustaceans probably related to branchiurans. In addition, gene arrangement comparisons strongly support an unforeseen assemblage of pentastomids with maxillopod and cephalocarid crustaceans, to the exclusion of remipedes, branchiopods, malacostracans and hexapods.

Full Text Available Need for Cognition (NFC is conceptualized as an individuals’ tendency to engage in and enjoy effortful cognitive activity and, thus, captures one’s cognitive engagement. It plays a well-established role in information processing in experimental or academic contexts. However, so far comparably little is known about its consequences for other than purely cognitive or academic outcomes. Indeed, NFC is positively associated with personality traits pertaining to Positive Emotionality (PE and negatively to traits related to Negative Emotionality (NE. Moreover, evidence suggests NFC to be related to an active, problem-focused coping style. We therefore hypothesized NFC to mediate between life events and individual differences in PE and NE. In a sample of N = 202 volunteers from the general population, we observed that the number of past positive and negative life events had direct effects on PE, and NE, respectively, and that for positive life events, a mediating effect on PE via NFC was observed, with a higher number of past positive life events being related to higher NFC that in turn was related to increased PE. Thus, the present results lend support to the notion of NFC as an important factor supporting personal well-being by way of its mediating role between the number of past positive life events and positive affect.

Sustainable interpersonal service relationships (SISRs) are the outcome of a design process that supports situated meaningful interactions between those being served and those in service. Service design is not just directed to simply satisfy the ability to perceive the psychological state of others, but more importantly, it should aim at preserving these relationships in relation to the contextual requirements that they functionally need, in order to be or remain sustainable. However, SISRs are uncertain since they have many possibilities to be in error in the sense that the constructed, situated meanings may finally be proven unsuccessful for the anticipations and the goals of those people engaged in a SISR. The endeavor of this paper is to show that aesthetic behavior plays a crucial role in the reduction of the uncertainty that characterizes such relationships. Aesthetic behavior, as an organized network of affective and cognitive processes, has an anticipatory evaluative function with a strong influence on perception by providing significance and value for those aspects in SISRs that exhibit many possibilities to serve goals that correspond to sustainable challenges. Thus, aesthetic behavior plays an important role in the construction of meanings that are related to both empathic and contextual aspects that constitute the entire situation in which a SISR takes place. Aesthetic behavior has a strong influence in meaning-making, motivating the selection of actions that contribute to our initial goal of interacting with uncertainty, to make the world a bit less puzzling and, thus, to improve our lives, or in other words, to design.

Benign paroxysmal positional vertigo (BPPV) is a labyrinthine disorder with a typical behavior: intense crises of rotational vertigo induced by postural changes of the head, with short duration and usually good responsiveness to rehabilitative maneuvers. This phenomenon is thought to be subsequent to the movement of floating particles in the labyrinthine fluids, which can provoke gravitational stimulations. In order to conduct a metabolic and autoimmune examination, 70 patients affected by BPPV were examined. In 34 cases (48.5%) autoimmune alterations were found: in 19 cases (27.1%) the level of anti-thyroid antibodies far exceeded the normal values with a significant incidence in comparison with a control group (Pvertigo.

Full Text Available In the 1960s tourism began its advance as an economic sector and went on to be promoted in developing countries as a possible solution to some of their problems. Given this fact, marketing has started to become a key element in the management of tourism and tourist destination, well prepared to bring attractiveness to the place, given the intensification of competition between tourist destinations strategies are necessary. However, when considering the success of the tourist destination in the long term, one must take into account the importance of the sustainability of the place, adopting strategies to make the competitive tourist destination without compromising their survival. Based on these facts, the study looked at the relationship between sustainable development and the image of the tourist destination in order to contribute to making strategic actions that promote the competitiveness of the place. A survey was done with 280 tourists, from which statistical analyzes and structural equation modeling were applied. The results showed the direct and positive influence of sustainable development on the image of the tourist destination, confirming its relevance as a factor to be considered in the marketing strategies for the competitiveness of the place.
Full Text Available As a result of the development of new industrialized countries, such as Brazil, China and other Southern Asian economies, as well as a globalized economy, traditional competitive paradigms based on advantages associated with costs and quality efficiencies or even innovation are no longer sufficient. These previous classical paradigms related competitiveness either to costs or technology innovation and the resources of industry incumbents. However, the combination of adequate knowledge and relationship management with marketing efforts brings forth a reconsideration of the present competitive models that go beyond those analyses from the point of view of global value chains. The objective of this investigation will analyze the governance structure of the territorial value chain in the Spanish and Italian ceramic tile industry, through the understanding of the previous and current roles of several industries involved in the value creation system. By way of both a case study and quantitative methodology approach, we will explore the paradigm change where traditional chain actors are losing their grip on their contribution to the territorial value creation system as new actors appear with a more stable status. The article concludes that proper positioning in the global value chain is a key strategy for the sustainability of the involved firms, especially Small and Medium Enterprises (SME.

Parent and peer relationships are important social resources for adolescents. South African research on adolescents' relationships, however, underemphasises these relationships as potential positive resources. Studies also tend to use samples from urban populations, while rural and semi-rural adolescent populations are neglected. This study focused on White and Coloured adolescents living in one South African semi-rural community and their ratings of positive and negative relationship qualities in relationships with parents and peers. Using the Network of Relationships Inventory (NRI), we found that mothers, best friends and romantic partners were relatively equal sources of social support. Mothers' high ratings for support, conflict and punishment may point to mothers bearing the primary responsibility for child care. Fathers' low support ratings raise concern as father involvement is important for adolescents' well-being. White participants overall rated their relationship higher for support and lower for negative qualities than the Coloured participants.

This study investigates the effects of acute stress on positive and negative relationship behaviors, specifically assurances and attention to alternatives. A sample of 129 college students were randomly assigned to either a high or low stress condition, then were led to believe they had the opportunity to interact with attractive potential relationship partners and list compliments about their current partner. Results indicated that those in the high stress condition gave their partner fewer assurances and paid more attention to alternatives. These results suggest that when individuals experience acute stress, they may engage in fewer positive relationship behaviors and more behaviors that are potentially harmful to their relationship.

Full Text Available Among land animals, more pork is eaten in the world than any other meat. The earth holds about one billion pigs who deliver over 100 mmt of pork to people for consumption. Systems of pork production changed from a forest-based to pasture-based to dirt lots and finally into specially-designed buildings. The world pork industry is variable and complex not just in production methods but in economics and cultural value. A systematic analysis of pork industry sustainability was performed. Sustainable production methods are considered at three levels using three examples in this paper: production system, penning system and for a production practice. A sustainability matrix was provided for each example. In a comparison of indoor vs. outdoor systems, the food safety/zoonoses concerns make current outdoor systems unsustainable. The choice of keeping pregnant sows in group pens or individual crates is complex in that the outcome of a sustainability assessment leads to the conclusion that group penning is more sustainable in the EU and certain USA states, but the individual crate is currently more sustainable in other USA states, Asia and Latin America. A comparison of conventional physical castration with immunological castration shows that the less-common immunological castration method is more sustainable (for a number of reasons. This paper provides a method to assess the sustainability of production systems and practices that take into account the best available science, human perception and culture, animal welfare, the environment, food safety, worker health and safety, and economics (including the cost of production and solving world hunger. This tool can be used in countries and regions where the table values of a sustainability matrix change based on local conditions. The sustainability matrix can be used to assess current systems and predict improved systems of the future.

Full Text Available This study examined the relationships between Big Six personality and entrepreneurial intention, inclusive of the mediating role of entrepreneurial self-efficacy in the Chinese context. Survey data from 280 college students reveal that Emotional Stability, Conscientiousness, Extraversion, and Interpersonal Relationship were positively associated with entrepreneurial intention. Agreeableness and Openness, however, had no effect on entrepreneurial intention in this study. Mediation analysis further indicated that Emotional Stability, Conscientiousness, Extraversion, and Interpersonal Relationship affected entrepreneurial self-efficacy, thus playing an indirect impact on entrepreneurial intention. In contrast, Agreeableness and Openness had no mediating role in the present study. These findings validate the bridge mechanism of entrepreneurial self-efficacy underlying the relationships between Big Six personality and entrepreneurial intention. These results highlight the direct role of sustainable personality as a predictor of entrepreneurial intention, especially as we note the decisive effect of the Interpersonal Relationship dimension in the Chinese context for the first time.

We aimed to test the relationships between Trust-in-God, positive and negative affect, and feelings of hope. A sample of university students (N = 282, 50 % female) completed the Positive and Negative Affect Schedule, the Adult Dispositional Hope Scale, and a Persian measure of Trust-in-God for Muslims. The results of a series of hierarchical regression analyses indicated that Trust-in-God was positively associated with participants' scores for hope and positive affect but was negatively associated with their scores for negative affect. The results support the relationship between Trust-in-God and indices of mental health.

Full Text Available This exploratory research examines the relationship between food entrepreneur sustainable orientation, mindset and firm sustainable practices in a mixed methods format. In particular we seek to address if entrepreneur behavior and firm practices are congruent with founding entrepreneur espoused support of sustainability. Our survey findings with thirty specialty food entrepreneurs suggest tenuous empirical support for the relationship of entrepreneur sustainable orientation, mindset and firm sustainable practices. However our qualitative results indicate positive relationships between sustainable orientation, mindset and practices. Evidence from this work highlights the critical role of founding entrepreneurs for successful implementation of sustainability along its multiple fronts including profitability.

The purpose of this study was to investigate the relationships between force fluctuation during isometric plantar flexion and the sustainable time for single-leg standing. Fourteen healthy males (21+/-1 years) performed unilateral (preferred leg) force matching tasks and single-leg quiet standing. Force matching tasks were performed to maintain isometric plantar flexion for 15 s at levels corresponding to 10% and 20% maximal voluntary contraction (MVC) with the visual feedback of force. Force fluctuation during force matching tasks was quantified as the standard deviation of force. Sustainable time for single-leg quiet standing was performed to maintain a single-leg quiet standing barefoot on a platform using the preferred leg with their eyes closed. Force fluctuation was significantly greater in 20% MVC task compared to 10% MVC task. The sustainable time for single-leg quiet standing was strongly correlated with force fluctuation in 20% MVC task (r=-0.56, p=0.04). However, it was not related to force fluctuation in 10% MVC task (r=0.19, p=0.52) or MVC value (r=0.13, p=0.65). These results suggest that a specificity of contraction intensity is observed between force steadiness and the posture stability during single-leg quiet standing; force steadiness during 20% MVC plantar flexion is one of the important components for posture stability during single-leg quiet standing.

Positive body image is defined as healthy body-related attitudes that go beyond the absence of distressful symptoms. A warm and secure relationship with an important other person has been linked with attitudes of acceptance and appreciation toward one's body as well as adaptive eating patterns. This study tested whether a warm and secure relationship with God was similarly related to positive body image. Undergraduate women completed self-report measures of religiosity, life satisfaction, body appreciation, body acceptance by others, functional orientation, and intuitive eating. Multiple regression analyses showed that relationship with God contributed variance to most of the well-being variables.

Objective One of the most noteworthy and robust findings in personality psychology is the relationship between extraversion and positive affect. Existing theories have debated the origins and nature of this relationship, offering both structural/fixed and environmental/dynamic explanations. We tested the novel and straightforward dynamic hypothesis that part of the reason trait extraversion predicts trait positive affect is through an increased propensity to enact extraverted states, which in turn leads to experiencing more positive affect states. Method We report five experience sampling studies (and a meta-analysis of primary studies) conducted in natural environments and laboratory settings in which undergraduate participants (N = 241) provided ratings of trait extraversion, trait positive affect, extraversion states, and positive affect states. Results Results of primary studies and the meta analysis showed that relationships between trait extraversion and trait positive affect were partially mediated by aggregated extraversion states and aggregated positive affect states. Conclusions The results supported our dynamic hypothesis and suggested that dynamic explanations of the relationship between trait extraversion and trait positive affect are compatible with structural explanations. An important implication of these findings is that individuals might be able to increase their happiness by self-regulating their extraverted states. PMID:22092066

Romantic relationship loss is associated with significant psychological distress for emerging adults. Intrusive memories of stressful events are typically associated with symptom severity; however, whether spontaneous positive memories of a relationship breakup may also be related to psychological...... symptoms has received little attention. We examined links between breakup-specific distress, depressive symptoms, and relationship memories of different valence. Ninety-one emerging adults (Mage = 20.13) who had experienced a recent romantic breakup recorded the frequency of positive and negative...... spontaneous relationship memories in a four-day online memory diary. Control memories were also recorded. Positive memories were specifically related to breakup distress, whereas negative memories were related to both breakup distress and depression. No such associations were found for the control memories...

Adolescence is marked by a steep increase in risk-taking behavior. The serious consequences of such heightened risk taking raise the importance of identifying protective factors. Despite its dynamic change during adolescence, family relationships remain a key source of influence for teenagers. Using a longitudinal fMRI approach, we scanned 23 adolescents twice across a 1.5-year period to examine how changes in parent-child relationships contribute to changes in adolescent risk taking over time via changes in adolescents' neural reactivity to rewards. Results indicate that although parent-child relationships are not associated with adolescent risk taking concurrently, increases in positive parent-child relationships contribute to declines in adolescent risk taking. This process is mediated by longitudinal decreases in ventral striatum activation to rewards during risk taking. Findings highlight the neural pathways through which improvements in positive parent-child relationships serve to buffer longitudinal increases in adolescent risk taking. Published by Elsevier Ltd.

Full Text Available The aim of this study was to examine whether the relationship between the ratio of job-related positive to negative emotions (positivity ratio and job burnout is best described as linear or curvilinear. Participants were 89 police officers (12% women and 86 firefighters. The positivity ratio was evaluated using the Job-related Affective Wellbeing Scale (Van Katwyk, Fox, Spector, & Kelloway, 2000. Exhaustion and disengagement, two components of job burnout, were measured using the Oldenburg Burnout Inventory (Demerouti, Mostert, & Bakker, 2010. The results of regression analysis revealed that curvilinear relationships between the positivity ratio and two components of job burnout appeared to better fit the data than linear relationships. The relationship between the positivity ratio and exhaustion was curvilinear with a curve point at around 2.1. A similar curvilinear relationship, but with a lower curve point, i.e., around 1.8, was observed for disengagement. It seems that beyond certain values there may be hidden costs of maintaining positive emotions at work. Also, the unequal curve points for subscales suggest that different dimensions of work-related functioning are variously prone to such costs.

Sustained inflation (SI) has been advocated as an alternative to intermittent positive pressure ventilation (IPPV) during the resuscitation of neonates at birth, to facilitate the early development of an effective functional residual capacity, reduce atelectotrauma and improve oxygenation after the birth of preterm infants. The primary aim was to review the available literature on the use of SI compared with IPPV at birth in preterm infants for major neonatal outcomes, including bronchopulmonary dysplasia (BPD) and death. MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials, until 6 October 2014. Randomised clinical trials comparing the effects of SI with IPPV at birth in preterm infants for neonatal outcomes. Descriptive and quantitative information was extracted; data were pooled using a random effects model. Heterogeneity was assessed using the Q statistic and I(2). Pooled analysis showed significant reduction in the need for mechanical ventilation within 72 h after birth (relative risk (RR) 0.87 (0.77 to 0.97), absolute risk reduction (ARR) -0.10 (-0.17 to -0.03), number needed to treat 10) in preterm infants treated with an initial SI compared with IPPV. However, significantly more infants treated with SI received treatment for patent ductus arteriosus (RR 1.27 (1.05 to 1.54), ARR 0.10 (0.03 to 0.16), number needed to harm 10). There were no differences in BPD, death at the latest follow-up and the combined outcome of death or BPD among survivors between the groups. Compared with IPPV, preterm infants initially treated with SI at birth required less mechanical ventilation with no improvement in the rate of BPD and/or death. The use of SI should be restricted to randomised trials until future studies demonstrate the efficacy and safety of this lung aeration manoeuvre. Published by the BMJ Publishing Group Limited.

Full Text Available The Environmental Sustainability Index (ESI was recently used to investigate links between sustainability and corruption. Here, we show that the ESI contradicts another widely used index of environmental sustainability, the Ecological Footprint (EF, with the result that the most sustainable nations under the ESI are the least sustainable under the EF. Consequently, opposite conclusions can be drawn from investigations into the causes of environmental sustainability, depending on which index is used.
Public health professionals have an opportunity to refocus national attention on food and nutrition policy, within a sustainability agenda. A broadly based national Food and Nutrition Policy was developed in 1992. However, its implementation has been selective and primarily based within the health sector. Other major policy areas, for example; industry, agriculture and trade, have dominated Australian nutrition and health policy. A broad, whole-of-government commitment to a comprehensive food and nutrition policy that engages with the community is required to achieve outcomes in terms of public health, a sustainable environment and viable food production for future generations.

Accelerating urbanization has been viewed as an important instrument for economic development and reducing regional income disparity in some developing countries, including China. Recent studies (Bloom et al. 2008) indicate that demographic urbanization level has no causal effect on economic growth. However, due to the varying and changing definition of urban population, the use of demographic indicators as a sole representing indicator for urbanization might be misleading. Here, we re-examine the causal relationship between urbanization and economic growth in Chinese cities and provinces in recent decades, using built-up areas as a landscape urbanization indicator. Our analysis shows that (1) larger cities, both in terms of population size and built-up area, and richer cities tend to gain more income, have larger built-up area expansion, and attract more population, than poorer cities or smaller cities; and (2) that there is a long-term bidirectional causality between urban built-up area expansion and GDP per capita at both city and provincial level, and a short-term bidirectional causality at provincial level, revealing a positive feedback between landscape urbanization and urban and regional economic growth in China. Our results suggest that urbanization, if measured by a landscape indicator, does have causal effect on economic growth in China, both within the city and with spillover effect to the region, and that urban land expansion is not only the consequences of economic growth in cities, but also drivers of such growth. The results also suggest that under its current economic growth model, it might be difficult for China to control urban expansion without sacrificing economic growth, and China's policy to stop the loss of agricultural land, for food security, might be challenged by its policy to promote economic growth through urbanization.
Full Text Available When beekeeping is managed on a migratory basis, the bee colony produces physical outputs (honey and pollination services on a sequence of forage sites. Forage sites are competitors if their flowering periods overlap, and are complementary otherwise. Viable sequences consist only of complementary forage sites. A part of the bee colony’s production time is spent on each forage site in the period when the crop or wild vegetation covering it is in flower. The total period covered by the sequence of sites, including the base site, must be equal to or less than the duration (365 days of the bee colony’s annual biological cycle. The migratory beekeeper draws up viable sequences of forage sites and calculates their profitability levels. Variations in the profitability of forage sites which alter the composition of the sequence, affecting provision of the non-marketed ecosystem pollination services, impact the biodiversity of the pollinated plants with trickle-down effects on sustainability. In the case of migratory beekeeping, there is, therefore, a sequential relationship between profitability and sustainability.

Romantic relationship loss is associated with significant psychological distress for emerging adults. Intrusive memories of stressful events are typically associated with symptom severity; however, whether spontaneous positive memories of a relationship breakup may also be related to psychological...... symptoms has received little attention. We examined links between breakup-specific distress, depressive symptoms, and relationship memories of different valence. Ninety-one emerging adults (Mage = 20.13) who had experienced a recent romantic breakup recorded the frequency of positive and negative....... The results suggest that experiences of positive memories are critical for understanding the degree of distress a young person may experience following a breakup. Possible explanations for these findings and similarities with the grief and bereavement literature are discussed....

We assessed the impact of thinking of a current romantic partner on acute blood glucose responses and positive affect over a short period of time. Participants in romantic relationships were randomly assigned to reflect on their partner, an opposite-sex friend, or their morning routine. Blood glucose levels were assessed prior to reflection, as well as at 10 and 25 min postreflection. Results revealed that individuals in the routine and friend conditions exhibited a decline in glucose over time, whereas individuals in the partner condition did not exhibit this decline (rather, a slight increase) in glucose over time. Reported positive affect following reflection was positively associated with increases in glucose, but only for individuals who reflected on their partner, suggesting this physiological response reflects eustress. These findings add to the literature on eustress in relationships and have implications for relationship processes. Copyright © 2014 Society for Psychophysiological Research.

Neural reflections of performance monitoring, including the error-related negativity (ERN) component of the event-related potential (ERP), are modulated by personality and affective constructs. Little is known, however, about the relationship between positive personality traits and neural indices of performance monitoring. We investigated the relationship between measures of positive personality traits, including satisfaction with life, dispositional optimism, and positive affect, and indices of performance monitoring in a sample of 45 neurologically-healthy individuals. Increased satisfaction with life was associated with decreased (i.e., less negative) ERN amplitude. Dispositional optimism and positive affect were not related to ERN amplitude. Results remained consistent when negative affect and measures of positive personality were accounted for using multiple regression. There were no relationships between measures of positive personality and the post-error positivity (Pe) or behavioral indices. Findings are consistent with an affective salience interpretation of the ERN, with errors potentially being less meaningful for individuals with higher satisfaction with life.

Full Text Available Given the rapidly developing processes in the housing market of China, the significant regional difference in housing prices has become a serious issue that requires a further understanding of the underlying mechanisms. Most of the extant regression models are standard global modeling techniques that do not take spatial non-stationarity into consideration, thereby making them unable to reflect the spatial nature of the data and introducing significant bias into the prediction results. In this study, the geographically weighted regression model (GWR was applied to examine the local association between housing price and its potential determinants, which were selected in view of the housing supply and demand in 338 cities across mainland China. Non-stationary relationships were obtained, and such observation could be summarized as follows: (1 the associations between land price and housing price are all significant and positive yet having different magnitudes; (2 the relationship between supplied amount of residential land and housing price is not statistically significant for 272 of the 338 cities, thereby indicating that the adjustment of supplied land has a slight effect on housing price for most cities; and (3 the significance, direction, and magnitude of the relationships between the other three factors (i.e., urbanization rate, average wage of urban employees, proportion of renters and housing price vary across the 338 cities. Based on these findings, this paper discusses some key issues relating to the spatial variations, combined with local economic conditions and suggests housing regulation policies that could facilitate the sustainable development of the Chinese housing market.

To investigate the relationship between acoustic signal typing and perceptual evaluation of sustained vowels produced by tracheoesophageal (TE) speakers and the use of signal typing in the clinical setting. Two evaluators independently categorized 1.75-second segments of narrow-band spectrograms according to acoustic signal typing and independently evaluated the recording of the same segments on a visual analog scale according to overall perceptual acoustic voice quality. The relationship between acoustic signal typing and overall voice quality (as a continuous scale and as a four-point ordinal scale) was investigated and the proportion of inter-rater agreement as well as the reliability between the two measures is reported. The agreement between signal type (I-IV) and ordinal voice quality (four-point scale) was low but significant, and there was a significant linear relationship between the variables. Signal type correctly predicted less than half of the voice quality data. There was a significant main effect of signal type on continuous voice quality scores with significant differences in median quality scores between signal types I-IV, I-III, and I-II. Signal typing can be used as an adjunct to perceptual and acoustic evaluation of the same stimuli for TE speech as part of a multidimensional evaluation protocol. Signal typing in its current form provides limited predictive information on voice quality, and there is significant overlap between signal types II and III and perceptual categories. Future work should consider whether the current four signal types could be refined. Copyright © 2015 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

Research has shown how academic emotions are related to achievement and to cognitive/motivational variables that promote achievement. Mediated models have been proposed to account for the relationships among academic emotions, cognitive/motivational variables, and achievement, and research has supported such mediated models, particularly with negative emotions. The study tested the hypotheses: (1) self-regulation and the positive academic emotions of enjoyment and pride are positive predictors of achievement; and (2) enjoyment and pride both moderate the relationship between self-regulation and achievement. Participants were 1,345 students enrolled in various trigonometry classes in one university. Participants answered the Academic Emotions Questionnaire-Math (Pekrun, Goetz, & Frenzel, 2005) and a self-regulation scale (Pintrich, Smith, Garcia, & McKeachie, 1991) halfway through their trigonometry class. The students' final grades in the course were regressed to self-regulation, positive emotions, and the interaction terms to test the moderation effects. Enjoyment and pride were both positive predictors of grades; more importantly, both moderated the relationship between self-regulation and grades. For students who report higher levels of both positive emotions, self-regulation was positively associated with grades. However, for those who report lower levels of pride, self-regulation was not related to grades; and, for those who reported lower levels of enjoyment, self-regulation was negatively related to grades. The results are discussed in terms of how positive emotions indicate positive appraisals of task/outcome value, and thus enhance the positive links between cognitive/motivational variables and learning. ©2012 The British Psychological Society.

Understanding the nature of emotional experience requires understanding the relationship between positive and negative affect. Two particularly important aspects of that relationship are the extent to which positive and negative affect are correlated with one another and the extent to which they co-occur. Some researchers have assumed that weak negative correlations imply greater co-occurrence (i.e., more mixed emotions) than do strong negative correlations, but others have noted that correlations may imply very little about co-occurrence. We investigated the relationship between the correlation between positive and negative affect and co-occurrence. Participants in each of 2 samples provided moment-to-moment happiness and sadness ratings as they watched an evocative film and listened to music. Results indicated (a) that 4 measures of the correlation between positive and negative affect were quite highly related to 1 another; (b) that the strength of the correlation between measures of mixed emotions varied considerably; (c) that correlational measures were generally (but not always) weakly correlated with mixed emotion measures; and (d) that bittersweet stimuli consistently led to elevations in mixed emotion measures but did not consistently weaken the correlation between positive and negative affect. Results highlight that the correlation between positive and negative affect and their co-occurrence are distinct aspects of the relationship between positive and negative affect. Such insight helps clarify the implications of existing work on age-related and cultural differences in emotional experience and sets the stage for greater understanding of the experience of mixed emotions.

The loss of forest area globally due to change of land use, the importance of forests in the conservation of biodiversity and in carbon and other biogeochemical cycles, together with the threat to forests from pollution and from the impacts of climate change, place forestry policy and practice at the center of global environmental and sustainability strategy. Forests provide important economic, environmental, social, and cultural benefits, so that in forestry, as in other areas of environmental policy and management, there are tensions between economic development and environmental protection. In this article we review the current information on global forest cover and condition, examine the international processes that relate to forest protection and to sustainable forest management, and look at the main forest certification schemes. We consider the link between the international processes and certification schemes and also their combined effectiveness. We conclude that in some regions of the world neither mechanism is achieving forest protection, while in others local or regional implementation is occurring and is having a significant impact. Choice of certification scheme and implementation of management standards are often influenced by a consideration of the associated costs, and there are some major issues over the monitoring of agreed actions and of the criteria and indicators of sustainability. There are currently a number of initiatives seeking to improve the operation of the international forestry framework (e.g., The Montreal Process, the Ministerial Convention of the Protection of Forests in Europe and European Union actions in Europe, the African Timber Organisation and International Tropical Timber Organisation initiative for African tropical forest, and the development of a worldwide voluntary agreement on forestry in the United Nations Forum on Forests). We suggest that there is a need to improve the connections between scientific understanding

Background The researcher role is highly debated in qualitative research. This article concerns the researcher-researched relationship. Methods A group of health science researchers anchored in various qualitative research traditions gathered in reflective group discussions over a period of two years. Results Efforts to establish an anti-authoritarian relationship between researcher and researched, negotiation of who actually “rules” the research agenda, and experiences of shifts in “inferior” and “superior” knowledge positions emerged as central and intertwined themes throughout the discussions. The dual role as both insider and outsider, characteristic of qualitative approaches, seemed to lead to power relations and researcher vulnerability which manifested in tangible ways. Conclusion Shifting positions and vulnerability surfaced in various ways in the projects. They nonetheless indicated a number of similar experiences which can shed light on the researcher-researched relationship. These issues could benefit from further discussion in the qualitative health research literature. PMID:27307132

Challenges of relational coping are well documented in the literature on couples and chronic illnesses, but there is significantly less research on the psychological aspects of couple relationships and HIV, particularly in international contexts. Coping with the uncertainty of illness progression, family planning, disclosure to friends and family, social isolation and stigma, fear of transmission, sexual intimacy, changes to social and physical functioning, and receiving and providing care pose special challenges for couples with discordant HIV statuses. This study examined the correlates of relationship satisfaction in Ugandan HIV-positive individuals seeking treatment at a community clinic. Relationship satisfaction of HIV-positive individuals was uniquely predicted by their couple identity and depression, underscoring the importance of mental and relational health in HIV/AIDS.

Cerebral hemorrhage has been shown to occur in animals experimentally infected with Streptococcus mutans carrying the collagen-binding Cnm gene. However, the relationship between cerebral microbleeds and oral hygiene, with a focus on Cnm gene-positive S. mutans infection, remains unclear. One hundred and thirty-nine subjects participated. The presence or absence of Cnm-positive S. mutans and its collagen-binding activity were investigated using saliva samples, and relationship with cerebral microbleeds detected on MRI investigated, including clinical information and oral parameters. Fifty-one subjects were identified as Cnm-positive S. mutans carriers (36.7%), with cerebral microbleeds being detected in 43 (30.9%). A significantly larger number of subjects carried Cnm-positive S. mutans in the cerebral microbleeds (+) group. S. mutans with Cnm collagen-binding ability was detected in 39 (28.1%) of all subjects, and the adjusted odds ratio for cerebral microbleeds in the Cnm-positive group was 14.4. Regarding the presence of cerebral microbleeds, no significant differences were noted in the number of remaining teeth, dental caries, or in classic arteriosclerosis risk factors. The occurrence of cerebral microbleeds was higher in subjects carrying Cnm-positive S. mutans, indicating that the presence of Cnm-positive S. mutans increases cerebral microbleeds, and is an independent risk for the development of cerebrovascular disorders. © 2015 John Wiley & Sons A/S.

Efforts to eliminate mother-to-child transmission of HIV in Tanzania are guided by a four-prong strategy advocated by the World Health Organization (WHO). Prong 2, prevention of unintended pregnancies among women living with HIV, has, however, received the least attention and contraceptive use to prevent unintended pregnancies remains low. This study explored the perceived barriers to the use of modern methods of contraception, and factors influencing contraceptive choice among HIV-positive women in urban Dar-es-Salaam, Tanzania. A qualitative multi-site study was conducted, utilising in-depth interviews and focus group discussions with 37 sexually active HIV-positive women aged between 20 and 44 years, attending three health facilities within Dar-es-Salaam. The theoretical framework was a patient centred model. Four barriers were identified: the influence of the women's spousal relationships; personal beliefs and the relationship of these in understanding her disease; the influence of the social demands on the woman and her relationships; and the importance of a woman's relationship with her healthcare provider/healthcare system. Being the bearers of bad news (HIV-positive status) the pregnant women experienced conflicts, violence, abandonment and rejection. The loss in negotiating power for the women was in relation to their intimate partners, but also in the patient-healthcare provider relationship. The role of the male partner as a barrier to contraceptive use cannot be understated. Therefore, the results suggest that healthcare providers should ensure patient-focused education and provide support that encompasses the importance of their relationships. Additional research is required to elucidate the functional association between contraceptive choices and personal and social relationships.

Previous researches have shown that people with higher fluid intelligence are more likely to detect the unexpected stimuli. The current study systematically explored the relationship between fluid intelligence and sustained inattentional blindness in children. In Experiment 1, we measured one hundred and seventy-nine 7-to-14-year-old children's fluid intelligence and sustained inattentional blindness. The results showed that fluid intelligence was negatively related to sustained inattentional blindness only in 7-to-8-year-old children. In Experiment 2, we explored sustained inattentional blindness in sixty children with high Raven's scores. We found that compared with children who have average Raven's scores aged 11-to-12 years old, children with high Raven's scores were unable to better avoid sustained inattentional blindness. In general, this research implies that the relation between fluid intelligence and sustained inattentional blindness is weak. Fluid intelligence could predict sustained inattentional blindness only when children do not have enough perceptual capacities to complete the primary task. Copyright © 2017 Elsevier Inc.

Gender-based power imbalances place women at significant risk for sexual violence, however, little research has examined this association among women living with HIV/AIDS. We performed a cross-sectional analysis of relationship power and sexual violence among HIV-positive women on anti-retroviral therapy in rural Uganda. Relationship power was measured using the Sexual Relationship Power Scale (SRPS), a validated measure consisting of two subscales: relationship control (RC) and decision-making dominance. We used multivariable logistic regression to test for associations between the SRPS and two dependent variables: recent forced sex and transactional sex. Higher relationship power (full SRPS) was associated with reduced odds of forced sex (AOR = 0.24; 95 % CI 0.07-0.80; p = 0.020). The association between higher relationship power and transactional sex was strong and in the expected direction, but not statistically significant (AOR = 0.47; 95 % CI 0.18-1.22; p = 0.119). Higher RC was associated with reduced odds of both forced sex (AOR = 0.18; 95 % CI 0.06-0.59; p women should consider approaches that increase women's power in their relationships.
Full Text Available Despite convincing evidence supporting the association between exercise and positive affect, this complex relationship requires further theoretical and person-centered explanation. The nature of one’s motivation for exercise, as postulated by Self-Determination Theory (SDT, may supply a missing and understudied link. The primary aim of this experimental study was to examine the moderating influence of situational motivation from SDT on the relationship between an acute bout of preferred exercise, namely running (vs. control, and changes in positive affect. Forty-one active women attended two sessions to engage in (a a 30-min moderate-intensity self-paced treadmill run and (b a 30-min quiet activity (i.e., newspaper reading. Participants with high introjection versus those with low introjection reported a greater increase in positive affect from pre- to postrunning and a greater decrease in positive affect from pre- to postcontrol. A “relief from guilt” effect was postulated to explain these results. Motivational variables accounted for 7% of variance in postrun positive affect. Consistent with SDT, running because one values this behavior and its benefits (i.e., identified regulation was significantly associated with postrun positive affect.
Full Text Available Abstract Background & aim: Poor quality sleep is very common in modern societies and has a significant negative impact on psychological and physiological Dimensions. The purpose of the present study was to investigate correlational relationships and draw up a positive and negative affect mediation model between the difficulty in regulation of emotion and quality of sleep. Methods: In this descriptive-correlational study, the participants of the study were selected through multi-stage cluster sampling. Then, the difficulty questionnaire was distributed in emotion regulation, affective and negative and sleep quality among the participants . Collected data was analyzed for descriptive, correlation, structural equation modeling to investigate the research objectives. Results: The results showed that there was a significant positive correlation between the difficulty components of emotion regulation and negative emotion with poor sleep quality and positive correlation between positive affection and high sleep quality (p <0.01. Also, the pattern of structural equation modeling indicates the role of mediating positive and negative affects in the relationship between the difficulty in regulation of emotion and sleep quality . Conclusions: The results supported the hypothesis that the difficulty in regulation of emotion interferes with the quality of sleep, and positive affection can have a moderating role in this regard.

Objectives A body of evidence indicates that women value relationship-centered aspects of well-being more than men do, while men value autonomy-centered aspects of well-being more than women do. The current study examined whether gender moderates relations between autonomy and positive relationships and interleukin-6 (IL-6), a cytokine associated with inflammatory processes. Aspects of well-being consistent with gender-linked values were expected to be most health-protective such that positive relationships would predict lower IL-6 only or more strongly in women, and autonomy would predict lower IL-6 only or more strongly in men. Methods In the first study, a sample of 119 older adults (55% female) living in Kentucky were visited in their homes for interviews and blood draws. In the second study, a sample of 1,028 adults (45% female) living across the United States (U.S.) underwent a telephone interview followed by a visit to a research center for blood draws. Results In the Kentucky sample, autonomy was quadratically related to IL-6 such that average autonomy predicted higher IL-6; this effect was stronger in men, providing support for our hypothesis only at above average levels of IL-6. In the U.S. national sample, more positive relationships were associated with lower IL-6 in women only. When the national sample was restricted to match the Kentucky sample, higher autonomy was associated with lower IL-6 in men only. Conclusions Results provide preliminary evidence for gender-specific effects of positive relationships and autonomy on IL-6. Further work is needed to establish the generalizability of these effects to different ages, cultures, and health statuses. PMID:22908985

The purpose of this study was to explore the formant-articulation relationships in corner vowels by acoustic analysis of speech signals and measuring tongue contour using ultrasonography. Eighteen healthy adults (8 men, 10 women), aged between 20 and 40 years, were enrolled. Speech signals of sustained vowels /ɑ/, /i/, and /u/ were recorded to obtain the first 2 formant frequencies. Tongue height, tongue advancement, and lengths of posterior tongue surface (LPTS) and anterior oral cavity (LAOC) were obtained using ultrasound image processing technique in order to examine the resonance mechanism of the oral vocal tract. LPTS and LAOC, as well as mean frequencies of the first and second formants, showed significant differences between sexes and among vowels. The first formant significantly and better correlated with LPTS than with tongue height (r = -.78, p < .001, Pearson's correlation). The correlation of the second formant with LAOC (r = -.85, p < .001) was also significant and better than the correlation with tongue advancement. Sex, however, did not show significant correlation with the formant frequencies. Ultrasonographic measurements of tongue contour correlated well to the formant frequencies. The results stressed the importance of tongue shaping in articulation. Although more studies are necessary in clinical implications, disorders associated with abnormal tongue shaping may be the target applications in the future.

The mutual-responding relationship between plants and environment is involved in all life processes, which are the essential bases for different types of sustainable development on the globe, particularly the critical basis for agricultural sustainable development. How to regulate the above relationship between plants and the corresponding environment (in particular soil environment) is the key problem to modern sustainable agriculture development under global climate change, which is one of the hot topics in the field of plant biology. Detailed dissection of this responding relationship is also important for conducting global eco-environmental restoration and construction. Although powerful methodology and dataset related to genomics, post-genomics, and metabolomics have provided some insights into this relationship, crop physiological measures are also critical for crop full performance in field. With the increase of tested plants (including model plants) and development of integrated molecular biology, a complete understanding of the relationship at different scales under biotic and abiotic stresses will be accelerated. In the current paper, we will cover some important aspects in combination with the recent work from our laboratory and related advances reflected by international academic journals, as follows: plant physiological function performance under natural condition, plant gene regulatory network system under abiotic stresses, gene regulatory network system and drought resistance improvement, summary of the related work from our laboratory, conclusions, and acknowledgement.

Full Text Available The purpose of this study was to compare the data/model fit for two competing theories of the conceptual roles that Negative Affectivity (NA and Positive Affectivity (PA play in the stressor-strain relationship. In the ‘trait model’, NA is understood to be a confounder that inflates the perceived work-related stressor-outcome relationship, while PA is unrelated to either stressors or strain. Alternatively, the ‘situational model’ assumes that NA and PA are directly affected by stressors and are thought to mediate the stressor-relationship. The sample consisted of 731 Swedish engine room officers. Role stress was used as a stressor indicator, perceived stress was the outcome measure, and the PANAS was used to assess levels of affectivity. The path analysis gave strong support for the work situational model (RMSEA = 0.034 while no support was found for the trait model. No moderating effects from affectivity were found.

The transition to parenthood is often associated with a decline in couple relationship adjustment. Couples (n = 71) expecting their first child were randomly assigned to either: (a) Becoming a Parent (BAP), a maternal parenting education program; or (b) Couple CARE for Parents (CCP), a couple relationship and parenting education program. Couples were assessed pre-intervention (last trimester of pregnancy), post-intervention (5 months postpartum), and follow-up (12 months postpartum). Relative to BAP, CCP reduced negative couple communication from pre- to post-intervention, and prevented erosion of relationship adjustment and self-regulation in women but not men from pre-intervention to follow-up. Mean parenting stress reflected positive adjustment to parenthood with no differences between BAP and CCP. CCP shows promise as a brief program that can enhance couple communication and women's adjustment to parenthood.

It is the position of the Academy of Nutrition and Dietetics that all people should have consistent access to an appropriately nutritious diet of food and water, coupled with a sanitary environment, adequate health services, and care that ensure a healthy and active life for all household members. The Academy supports policies, systems, programs, and practices that work with developing nations to achieve nutrition security and self-sufficiency while being environmentally and economically sustainable. For nations to achieve nutrition security, all people must have access to a variety of nutritious foods and potable drinking water; knowledge, resources, and skills for healthy living; prevention, treatment, and care for diseases affecting nutrition status; and safety-net systems during crisis situations, such as natural disasters or deleterious social and political systems. More than 2 billion people are micronutrient deficient; 1.5 billion people are overweight or obese; 870 million people have inadequate food energy intake; and 783 million people lack potable drinking water. Adequate nutrient intake is a concern, independent of weight status. Although this article focuses on nutritional deficiencies in developing nations, global solutions for excesses and deficiencies need to be addressed. In an effort to achieve nutrition security, lifestyles, policies, and systems (eg, food, water, health, energy, education/knowledge, and economic) contributing to sustainable resource use, environmental management, health promotion, economic stability, and positive social environments are required. Food and nutrition practitioners can get involved in promoting and implementing effective and sustainable policies, systems, programs, and practices that support individual, community, and national efforts.

Body size is frequently claimed to be a major determinant of animal trophic interactions, yet few studies have explored relationships between body size and trophic interactions in rivers, especially within the tropics. We examined relationships between body size and trophic position (TP) within fish assemblages in four lowland rivers of the Lower Mekong Basin in Cambodia. Stable isotope analysis (based on δ15N) was used to estimate TP of common fish species in each river, and species were classified according to occupation of benthic versus pelagic habitats and major feeding guilds. Regression analysis yielded strong correlations between body size and TP among fishes from the Sesan and Sreprok rivers, but not those from the Mekong and Sekong rivers. The Mekong fish assemblage had higher average TP compared with those of other rivers. The relationship between body size and TP was positive and significantly correlated for piscivores and omnivores, but not for detritivores and insectivores. The body size–TP relationship did not differ between pelagic and benthic fishes. Body size significantly predicted TP within the orders Siluriformes and Perciformes, but not for Cypriniformes, the most species-rich and ecologically diverse order in the Lower Mekong River. We conclude that for species-rich, tropical fish assemblages with many detritivores and invertivores, body size would not be an appropriate surrogate for TP in food web models and other ecological applications.

Individuals with a positive body image appreciate their bodies, hold an internal perspective of their bodies, and are satisfied with the functionality of their bodies. Research shows that positive body image is more complex than the absence of body dissatisfaction. Although exercise reduces women's body dissatisfaction, very little research has explored how, or even whether, exercise is associated with positive body image. Therefore, we examined whether exercise frequency was positively related to three aspects of positive body image (body appreciation, internal body orientation, and functional body satisfaction) among 321 college women. Appearance-based exercise motivation (the extent exercise is pursued to influence weight or shape) was hypothesized to moderate these associations. Hierarchical moderated regression analyses showed that exercise frequency was related to higher positive body image, but high levels of appearance-based exercise motivation weakened these relationships. Thus, messages promoting exercise need to de-emphasize weight loss and appearance for positive body image. Copyright © 2014 Elsevier Ltd. All rights reserved.

Research has consistently found that religiousness and spirituality are negatively associated with underage drinking. However, there is a paucity of research exploring the mechanisms by which these variables influence this important outcome. With 344 underage young adults (ages 18-20; 61 % women), we investigated positive alcohol expectancies as a mediator between religiousness and spirituality (measured separately) and underage alcohol use. Participants completed the Religious Commitment Inventory-10, Daily Spiritual Experiences Scale, Alcohol Expectancies Questionnaire, and Drinking Styles Questionnaire. Results indicate less positive alcohol expectancies partially mediate the relationship between both religiousness and spirituality and underage alcohol use. This suggests religiousness and spirituality's protective influence on underage drinking is partly due to their influence on expectations about alcohol's positive effects. Since underage drinking predicts problem drinking later in life and places one at risk for serious physical and mental health problems, it is important to identify specific points of intervention, including expectations about alcohol that rise from religious and spiritual factors.

Teacher-child relationships (TCRs) are important factors in socio-emotional development and academic and behavioural outcomes. In Japan, occupational therapists (OTs) work with teachers and children with intellectual disabilities (ID) in school environment considering TCRs. This study aimed to identify positive indicators in TCRs among children with ID. We conducted interviews with 23 Japanese preschool teachers working with children with ID in child development support centres (CDSCs) and used the Delphi method to evaluate and select positive indicators. We obtained 49 positive indicators belonging to 15 conceptual indicators related to TCRs. The indicators that reached a high degree of agreement and consensus seems to be related to more fundamental social interaction aspects. These indicators could be used to enhance collaboration between OTs and teachers in the school environment, including CDSCs. We could not examine differences of positive social aspects depending on diagnostic features. It will be important for future work to examine differences in positive social aspects among children with other diagnostic features. Our findings could contribute to the development of an assessment tool to evaluate positive aspects of teacher-child interactions and their progress. Copyright © 2015 John Wiley & Sons, Ltd.

Engaging in teamwork requires a clear understanding of positive and negative behaviours that act as facilitators and barriers to collegial workplace relationships. Identifying and correcting underlying barriers, while promoting facilitators, is fundamental to improving care delivery and, ultimately, clinical outcomes. Despite a considerable amount of literature in this area, there is a lack of clarity of the different behaviours as several parallel literatures address similar questions about antecedents, processes and outcomes. The purpose of this study is to synthesise the current state of literature reporting on behaviours in workplace relationships. Using a scoping review methodology, the following research question will be addressed: "What is known about positive and negative behaviours in workplace relationships?" We will employ the methodological frameworks used by Arksey and O'Malley and Levac et al. The search strategy will include numerous electronic databases, grey literature sources and hand-searching of reference lists from 1990 to present with a limit to English language. Search strategies will be developed using controlled vocabulary and keyword terms related to various components of workplace relationships. Two reviewers will independently screen titles and abstracts for inclusion, followed by screening of the full text of potential articles to determine final inclusion. A descriptive numerical analysis will describe characteristics of included studies. A thematic analysis will provide an overview of the literature, including definitions, conceptual frameworks, antecedents, outcomes and interventions. In reviewing a wide range of positive and negative behaviours, then integrating into a manageable, meaningful whole, this study is a critical step in helping policymakers, leaders and healthcare professionals effectively use what is known thus far. Knowledge translation activities will occur throughout the study with dissemination of findings to local

Brazilian teenagers report problematic patterns of alcohol consumption. Alcohol advertising strategies are one of the main factors influencing adolescents' alcohol consumption. The aim of this study was to evaluate the relationship between positive responses to TV beer commercials, exposure, and alcohol consumption. Thirty-two recent TV commercials were shown to 133 high school students from public schools in São Bernardo do Campo, São Paulo State, Brazil. The subjects recorded how well they liked the ads and how often they had already watched each commercial. The teenagers also reported their alcohol consumption rates. The ten commercials analyzed in this article were the five most popular and the five least popular. The analysis showed that subjects had already seen the five most popular ads, but not the five least popular. In addition, the five most popular ads received higher scores from teenagers that reported having consumed beer during the previous month. The study found a positive relationship between enjoying beer advertising and exposure to beer ads, as well as between alcohol consumption and positive responses to alcohol commercials.

The aim of this study was to investigate the effects of sustained computer keyboard typing on the human musculoskeletal system by assessing the pressure-pain threshold (PPT), scapular position and activation of the upper trapezius. Vertical and horizontal positional changes of the scapular were measured with a palpation meter before and after keyboard work, and the PPT was measured using a pressure algometer. Activation of the upper trapezius during 20 minutes of computer keyboard work was measured by electromyography, and four consecutive 5-minute segments were analyzed. The vertical distance from the seventh cervical process to the acromion, and the horizontal distance from the inferior angle to the same level of the spinal process were significantly increased after keyboard typing work compared with before keyboard typing work (ptrapezius activity increased with increased time at the keyboard. The percent reference voluntary contraction of phase 1 (from start to 5 minutes) was lower than those of phase 2 (from 5 to 10 minutes), and phase 3 (from 10 to 15 minutes) (ptrapezius. To prevent musculoskeletal problems in the shoulder region, posture reeducation during computer work should be considered in terms not only of neck and trunk posture, but also of scapular position.

Populations of laboratory animals that are selected for increased lifespan often show negative correlated responses in early fecundity. However, late fecundity and/or total lifetime fecundity can be higher in the populations selected for increased lifespan. This has been interpreted by some as being at odds with the disposable soma theory, which predicts decreased lifespan to increase total reproductive output. Alternatively, the Y-model explores the effects of variation in resource allocation and acquisition on life histories. In this model, a negative relationship between lifespan and reproduction can be viewed as variation in allocation, whereas a positive relationship is the result of variation in acquisition. However, a frequently neglected complication of the Y-model is that older individuals often show a decline in resource acquisition. Therefore, differential allocation to maintenance and survival might affect this decline in late-life acquisition which will affect resource availability across the whole lifespan. In this paper we show that a model which incorporates the ideas of the Y-model, the disposable soma theory, and an age-related decrease in resource acquisition, i.e. feeding senescence, can explain how the relationship between fecundity and lifespan changes with age. Furthermore, by modeling environments with contrasting extrinsic mortality rates, we explored how the outcome of the model depended on the relative importance of early and late-life reproduction. In high mortality environments a relatively higher early fecundity, lower late fecundity, and lower lifespans were more optimal, whereas the opposite was true for low mortality environments. We applied predictions from the model to a cohort of individually-housed female Drosophila melanogaster flies for which we measured age specific fecundity and lifespan. Early fecundity was negatively associated with lifespan, while late fecundity related positively with lifespan in the same cohort. This
Full Text Available Starting from the theory of the Investment Development Path (IDP and competitive advantages, this study presents an econometrical approach of the relationship between net outward investment position, given by the net outward investment per capita (NOI, and innovation capabilities, reflected by the global innovation index (GII. The results of the analysis carried out for the worldwide economies, in the year 2013, using five models demonstrate that there is no significant correlation between NOI, as dependent variable, and GII as independent one. Thus, the highest coefficient of determination value was .201 (cubic model, reflecting the fact that only 20.1% of the variation in the NOI is explained by GII. Therefore, the level of country’s innovation capacities is not one of the main forces that determine its NOI position.

These variables are elementary for the practice of Nursing; however, their study is small within intercultural environments. The objective of this research is to know the association between self-esteem and happiness among Intercultural Nursing students from the positive psychology.Method: A quantitative, descriptive, transversal and correlational, research with a non-experimental design was realized, with a sample of 55 students of Intercultural Nursing. Two questionnaires were applied: the scale of Rosenberg self-esteem and happiness of Lima scale.Results: High levels of self-esteem and happiness were obtained. Through correlation of Pearson and hierarchical regression we found that self-esteem is associated in negative and positive way with certain factors of happiness; the same thing happened in the level of influence.Conclusion: In positive psychology is possible to associate variables such as self-esteem and happiness as strengths. Much more in the case of Intercultural Nursing students which have the aim to contribute to the indigenous communities development, that require nurses with favorable levels of self-esteem and the perception of subjective well-being to counteract an historical legacy of backwardness. From positive psychology is possible that this educational model will contribute to the mutual enrichment and empowerment within the work of the Intercultural Nursing.

The study of empathy and its role in companies is important because it is not yet widely known the benefits that can provide to any institution. The study attempt to show a full mediating role of empathy in this relationship. The sample consist on 69 work teams, from 7 Small -and Medium- sized Enterprises (SMEs including 4 educational institutions and 3 institutions of medical services from Spain. The Interclass Correlation Coefficients (ICC1 and ICC2 and the Average Deviation Index (ADM(J supports data aggregation at the team level. The results using SEM, through work teams, supported the hypothesis, that is, the empathy plays a full mediating role between transformational leadership and excellent team performance. Finally, theoretical and practical implications of the results are discussed.
Full Text Available According to research that have been conducted in the field of gerontology, sociology and psychology of ageing, there is a relationship between the level of religious involvement and health status/ well-being/quality of life in older age. How does religiousness influence aging process and health status? The aim of the article is to review explanations of a positive relationship between religiousness and health that are discussed in the literature. Those explanations may be grouped in three broad categories reflecting three functions of religion that play a role for well-being in older age. Those functions are: (1 religiousness as a source of coherence and the role of religious coping and provision of meaning in dealing with stressful life events (including ageing losses (2 religiousness as a source of positive self-perception and a sense of personal control, (3 provision of social resources (i.e. social ties and social support within religious community and emphasis on interpersonal relations (with special focus on forgiveness as a norm in interpersonal relations. Those functions of religion are discussed in the context of their potential role in successful ageing, as determined by - among others - active engagement in life.

Full Text Available Abstract Background Several familial Alzheimer disease (FAD mutations within the transmembrane region of the amyloid precursor protein (APP increase the Aβ42/40 ratio without increasing total Aβ production. In the present study, we analyzed the impact of FAD mutations and γ-secretase modulators (GSMs that alter the Aβ42/40 ratio on APP C-terminus (CT positioning relative to the membrane, reasoning that changes in the alignment of the APP intramembranous domain and presenilin 1 (PS1 may impact the PS1/γ-secretase cleavage site on APP. Results By using a Förster resonance energy transfer (FRET-based technique, fluorescent lifetime imaging microscopy (FLIM, we show that Aβ42/40 ratio-modulating factors which target either APP substrate or PS1/γ-secretase affect proximity of the APP-CT to the membrane and change PS1 conformation. Conclusions Thus, we propose that there is a reciprocal relationship between APP-CT positioning relative to the membrane and PS1 conformation, suggesting that factors that modulate either APP positioning in the membrane or PS1 conformation could be exploited therapeutically.

Research has shown that spirituality has a positive effect on mental and physical health; however, few studies have explored the influence of spirituality on purpose in life and well-being in persons living with HIV. This descriptive cross-sectional study was designed to examine the relationship between spirituality, purpose in life, and well-being in a sample of 46 HIV-positive men and women. Spirituality was measured using the Spiritual Involvement and Beliefs Scale-Revised (SIBS-R), purpose in life was measured using the Purpose in Life (PIL) test, and well-being was measured using the General Well-Being (GWB) Schedule. Demographic data on gender, age, length of time living with diagnosis of HIV/AIDS, employment status, and religious affiliation were also collected. Spirituality was reported to be significantly correlated with purpose in life (r = .295, p = .049) but not with well-being (r = .261, p = .084). Additionally, the SIBS-R, PIL, and GWB had alpha coefficients greater than .83, suggesting they are reliable and valid measures for this population of HIV-positive persons. The result that spirituality and purpose in life were significantly correlated offers the potential for designing nursing interventions and care delivery approaches that support psychological adaptation to HIV. Further studies with larger and more diverse samples are needed to better understand the role of well-being in healing.
Full Text Available Objective. Human evidence is limited regarding the interaction between oxidative stress biomarkers and chemokines, especially in a population of adults without overt clinical disease. The current study aims to examine the possible relationships of antioxidant and lipid peroxidation markers with several chemokines in adults. Methods. We assessed cross-sectional associations of total antioxidant status (TAS and two lipid peroxidation markers malondialdehyde (MDA and thiobarbituric acid reactive substances (TBARS with a suite of serum chemokines, including CXCL-1 (GRO-α, CXCL-8 (IL-8, CXCL-10 (IP-10, CCL-2 (MCP-1, CCL-5 (RANTES, CCL-8 (MCP-2, CCL-11 (Eotaxin-1, and CCL-17 (TARC, among 104 Chinese adults without serious preexisting clinical conditions in Beijing before 2008 Olympics. Results. TAS showed significantly positive correlations with MCP-1 (r=0.15751, P=0.0014, MCP-2 (r=0.3721, P=0.0001, Eotaxin-1 (r=0.39598, P<0.0001, and TARC (r=0.27149, P=0.0053. The positive correlations remained unchanged after controlling for age, sex, body mass index, smoking, and alcohol drinking status. No associations were found between any of the chemokines measured in this study and MDA or TBARS. Similar patterns were observed when the analyses were limited to nonsmokers. Conclusion. Total antioxidant status is positively associated with several chemokines in this adult population.

Anthropogenic climate warming has already affected the population dynamics of numerous species and is predicted to do so also in the future. To predict the effects of climate change, it is important to know whether productivity is linked to temperature, and whether species' traits affect responses to climate change. To address these objectives, we analysed monitoring data from the Finnish constant effort site ringing scheme collected in 1987-2013 for 20 common songbird species together with climatic data. Warm spring temperature had a positive linear relationship with productivity across the community of 20 species independent of species' traits (realized thermal niche or migration behaviour), suggesting that even the warmest spring temperatures remained below the thermal optimum for reproduction, possibly due to our boreal study area being closer to the cold edge of all study species' distributions. The result also suggests a lack of mismatch between the timing of breeding and peak availability of invertebrate food of the study species. Productivity was positively related to annual growth rates in long-distance migrants, but not in short-distance migrants. Across the 27-year study period, temporal trends in productivity were mostly absent. The population sizes of species with colder thermal niches had decreasing trends, which were not related to temperature responses or temporal trends in productivity. The positive connection between spring temperature and productivity suggests that climate warming has potential to increase the productivity in bird species in the boreal zone, at least in the short term.

The aim of this study was to investigate the relationship between the position of the upper and lower incisors and cortical bone thickness and CT value of mandibular symphysis obtained by CT images and cephalograms. The specimens were 24 dry skulls of mordern Japanese males (mean age 29 years) without marked crowding and missing tooth, which had been preserved in the Tokyou University Museum. The data were transferred to a workstation, and CT value and thickness of cortical bone were measured. The dentofacial morphology was investigated with a lateral cephalogram. The results were as follows; The thickness of cortal bone was more thicker in order of basal, lingual and labial cortical bone. The CT value showed the same tendency as cortical bone thickness. Significant correlation coefficients were found between cortical bone thickness and CT value in 30, 60, 90, 120 degree areas. The inclination of upper incisors was negatively related to the CT value in basal and lingual region of symphysis. The inclination of lower incisors was positively related to the CT value in basal and lingual region of symphysis. The interincisor angle was positively related to the CT value in basal region of symphysis. In conclusion, the results of this study suggested that the labio-lingual inclination of the upper and lower incisors was associated with the CT value of basal region of sysphysis. It is suggested that the internal structures of symphysis which relate to the occlusion types of incisors are affected by function of masticatory muscles. (author)

The aim of the study was to assess the semen quality and levels of spermatozoal nuclear DNA fragmentation in subfertile subjects clinically diagnosed with varicocele, subfertile subjects without varicocele and healthy fertile controls. Semen samples were obtained from 302 subjects. Of them, 115 were healthy fertile controls having normal semen characteristics, 121 subfertile men diagnosed with varicocele, both, clinically and on ultrasonography, while 66 subjects were subfertile with no varicocele. Spermatozoal concentration, percentage motility, morphology and DNA fragmentation were measured. In the study population, deterioration in semen quality-decreased spermatozoal concentration, percentage motility and normal morphology was seen in subfertile subjects, especially with varicocele. Highest spermatozoal DNA fragmentation was observed in varicocele-positive subjects as compared with varicocele-negative subjects and healthy fertile controls. Significant negative correlation was seen between spermatozoal DNA fragmentation and concentration (r = -0.310), motility (r = -0.328) normal morphology, WHO method (r = -0.221) and Tygerberg strict criteria (r = -0.180) in the varicocele-positive subfertile subjects. In conclusion, this study suggests existence of a negative relationship between spermatozoal DNA fragmentation and semen quality in varicocele-positive subfertile subjects. © 2014 Blackwell Verlag GmbH.

Scant evidence is available on the relationship between preferences for organic, local, sustainable, and nonprocessed foods (ie, alternative food production practices) and dietary quality. This cross-sectional study examined the characteristics and dietary behaviors (eg, consumption of fruits, vegetables, fast food) of young adults who reported placing low, moderate, or high importance on alternative food production practices. A diverse sample of 1,201 students at a 2-year community college and a 4-year public university in the Twin Cities, MN, completed the Student Health and Wellness Study survey in spring 2010. χ(2) tests examined differences in attitudes across demographic characteristics. Linear regression adjusted dietary intake across attitudes. About half (49%) of young adults placed moderate to high importance on alternative production practices, and few demographic differences across attitudes were found. Young adults who placed high importance on alternative production practices consumed 1.3 more servings of fruits and vegetables (Pfood production practices also consumed breakfast approximately 1 more day per week and fast food half as often as those who placed low importance on these practices (Pfood production practices may be well received by this age group. Experimental studies are needed to investigate whether attitudes toward alternative production practices can be manipulated to improve dietary quality.

Full Text Available For the past 12 years, Facebook has played a significant role in mediating the lives of its users. Disclosures on the site go on to serve as intimate, co-constructed life records, albeit with unique and always-evolving affordances. The ways in which romantic relationships are mediated on the site are complex and contested: “What is the significance of articulating a romantic relationship on Facebook?” “Why do some choose to make socially and culturally critical moments like the beginning and ends of relationships visible on Facebook, whereas others (perhaps within the same relationship do not?” “How do these practices change over time?” and “When is it time to go “Facebook official”?” In this article, we draw on qualitative research with Facebook users in their 20s in Australia and the United Kingdom who have been using the site for 5 years or more. Interviews with participants revealed that romantic relationships were central to many of their growing up narratives, and in this article, we draw out examples to discuss four kinds of (non-exclusive practices: (1 overt relationship status disclosures, mediated through the “relationship status” affordance of the site, (2 implied relationship disclosures, mediated through an increase in images and tags featuring romantic partners, (3 the intended absence of relationship visibility, and (4 later-erased or revised relationship disclosures. We also critique the ways in which Facebook might work to produce normative “relationship traces,” privileging neat linearity, monogamy, and obfuscating (perhaps usefully, perhaps not the messy complexity of romantic relationships.

Owing to the significant increase of mild motor delays and the strong intolerance of infants to be placed on prone position observed in the Physiotherapy Unit of the Maternal and Children's University Hospital of the Canaries (HUMIC), a study was conducted to determine whether positioning infants in the prone position while awake affected the achievement and quality of head control at three months. A prospective comparative practice-based study of a representative sample of 67 healthy infants born in the HUMIC, and divided into an experimental group (n = 35) and control group (n = 32). The Alberta Infant Motor Scale (AIMS) and a parent questionnaire were used as measurement tools. The intervention consisted of regular home visits to the experimental group (from the first to the third month). The two groups were evaluated in their homes at the end of 3 months. The differences in mean raw score of the AIMS at 3 months were, 16.26 in the experimental group and 10.38 in control group (P<.001). The percentile mean was 94 in the experimental group, and less than 50 (42) in the control group. All of the experimental group babies achieved the head control, with only 8 in the control group (25%). The significant findings suggest a direct relationship between the time spent in the prone position when the baby is awake and the achievement of head control at three months.

Cancer can be a life-threatening illness; however, it can also be a source of positive life changes, the posttraumatic growth (PTG) that comes from struggling with this serious illness. This cross-sectional study examines the sociodemographic and cancer-related predictors of PTG following a diagnosis of cancer. In addition, the relationships among adult attachment, health-related quality of life, and PTG are investigated. Measuring adult attachment is important because it can greatly influence the response to a highly distressing event, like facing cancer. Immediately before undergoing radiotherapy, 152 patients with breast or prostate cancer (mean = 59.1 years old, SD = 10.7) who had received a positive diagnosis within an average of 3.5 months prior to treatment were tested for measures of PTG, adult attachment, and health-related quality of life. Patients also completed a questionnaire regarding medical and sociodemographic characteristics. Hierarchical multiple regression analyses were conducted to reveal the significant predictors of PTG total score and PTG subscale scores. Younger age was a significant predictor of the PTG total score and New Possibilities subscale score. Subjective severity of cancer was positively associated with the PTG total score and scores on the Appreciation of Life and New Possibilities subscales. Regarding health-related quality of life, analyses indicated that greater social/family well-being significantly predicted greater PTG total score and higher scores on the New Possibilities, Spiritual Change, Appreciation of Life, and Relating to Others subscales. Finally, dismissive attachment style predicted fewer scores on the Personal Strength and Relating to Others subscales. These findings suggest that in addition to quality of life and adult attachment, sociodemographic and cancer-related variables may significantly contribute to positive growth.
Full Text Available In this article, the existence of a unique solution of Fredholm–Volterra integral equation of the second kind is guaranteed. The Fredholm integral term is assumed in position with bad kernel, while the Volterra integral term is considered in time with continuous kernel. Under certain conditions and new discussions, the bad kernel will tend to a logarithmic kernel. Then, using Chebyshev polynomial, a main theorem of spectral relationships of Fredholm integral equation of the first kind with logarithmic kernel multiplying by a smooth kernel is stated and used to obtain numerically the Fredholm–Volterra integral equation of the second kind. Finally, numerical results are obtained and the error, in each case, is computed.
Background Previous studies on nutrition counselling self-efficacy assessed small groups of dietitians in focused practice areas or evaluated the effectiveness of skills training on only a few skills. This descriptive study developed a comprehensive scale to examine self-efficacy in a large, cross-sectional sample of practising dietitians in performing various counselling skills that promote dietary behaviour changes. Methods A valid and reliable instrument was developed and administered through the Internet to survey dietitians in the United States from various areas of dietetics and with varying years of experience. Items included counselling self-efficacy, skill usage, and counselling-related job characteristics. Of 612 respondents, one group (n=486) conducted counselling more than 50% of their work week; the other group (n=126) less than 50%. Factor analysis was used for scale development. Independent samples t-tests and chi-square tests were performed for group comparisons. Correlations and multiple regression analyses further assessed the relationships among variables. Results The resultant unidimensional scale contained 25 items. Dietitians reported high self-efficacy scores and frequent skill usage. Those who counsel more than 50% of their work week were more likely to work in outpatient settings and private practice; reported higher self-efficacy scores, and held longer and repeated sessions. Self-efficacy scores were positively correlated with counselling-related job characteristics. Years of counselling experience and skill usage significantly predicted self-efficacy scores. Conclusion Dietitians perceive themselves to be highly self-efficacious in using counselling skills which may contribute positively to their professional practice. However, the relationship between counselling self-efficacy and actual performance warrants future investigation. PMID:20113386
The environmental determinants of public health and social equity present many challenges to a sustainable urbanism-climate change, water shortages and oil dependency to name a few. There are many pathways from urban environments to human health. Numerous links have been described but some underlying mechanisms behind these relationships are less understood. Combining theory and methods is a way of understanding and explaining how the underlying structures of urban environments relate to public health and social equity. This paper proposes a model for an ecological public health, which can be used to explore these relationships. Four principles of an ecological public health-conviviality, equity, sustainability and global responsibility-are used to derive theoretical concepts that can inform ecological public health thinking, which, among other things, provides a way of exploring the underlying mechanisms that link urban environments to public health and social equity. Theories of more-than-human agency inform ways of living together (conviviality) in urban areas. Political ecology links the equity concerns about environmental and social justice. Resilience thinking offers a better way of coming to grips with sustainability. Integrating ecological ethics into public health considers the global consequences of local urban living and thus attends to global responsibility. This way of looking at the relationships between urban environments, public health and social equity answers the call to craft an ecological public health for the twenty-first century by re-imagining public health in a way that acknowledges humans as part of the ecosystem, not separate from it, though not central to it. © The Author (2013).

The present study tests how positive family relationships and religious affiliation mediate between negative familial and social environments, and adolescent illicit drug abuse/dependence symptoms. The theoretical framework is based on an integration of two theories: the ecological model of human development (Bronfenbrenner, 1979) and the social development model (Hawkins & Weis, 1985). We used a stratified random sample of 401 American Indian adolescents. A path analysis tested the integrative theoretical model. Findings showed that positive family relationships mediated the negative impact of addicted family members, violence victimization, and negative school environment on illicit drug abuse/dependence symptoms. Religious affiliation mediated the negative effect of deviant peers on positive family relationships. Intervention and prevention efforts may benefit from promoting positive family relationships and religious affiliation to reduce the impact of complex familial and social problems on illicit drug symptoms. 2010 Elsevier Ltd.

Globally, irrigated agriculture is the largest abstractor, and predominant consumer, of groundwater resources, with large groundwater-dependent agro-economies now having widely evolved especially in Asia. Such use is also causing resource depletion and degradation in more arid and drought-prone regions. In addition crop cultivation practices on irrigated land exert a major influence on groundwater recharge. The interrelationship is such that cross-sector action is required to agree more sustainable land and water management policies, and this paper presents an integrated vision of the challenges in this regard. It is recognised that 'institutional arrangements' are critical to the local implementation of management policies, although the focus here is limited to the conceptual understanding needed for formulation of an integrated policy and some practical interventions required to promote more sustainable groundwater irrigation.
Full Text Available This paper uses Granger causality tests on a fiscal sustainability indicator (FSI and currency crises for 17 countries to evaluate the direction of causality between the FSI and currency crises. The FSI developed by Croce and Juan-Ramón (2003 is used. Also, different definitions for currency crises are used to evaluate whether they induce different results in the analysis. In general, the results suggest evidence of causality between the lagged FSI and currency crises.

Various methods for evaluating laparoscopic skill have been reported, but without detailed information on the configuration used they are difficult to reproduce. Here we present a method based on the trigonometric relationships between the instruments used in a laparoscopic training platform in order to provide a tool to aid in the reproducible assessment of surgical laparoscopic technique. The positions of the instruments were represented using triangles. Basic trigonometry was used to objectively establish the distances among the working ports RL, the placement of the optical port h', and the placement of the surgical target OT. The optimal configuration of a training platform depends on the selected working angles, the intracorporeal/extracorporeal lengths of the instrument, and the depth of the surgical target. We demonstrate that some distances, angles, and positions of the instruments are inappropriate for satisfactory laparoscopy. By applying basic trigonometric principles we can determine the ideal placement of the working ports and the optics in a simple, precise, and objective way. In addition, because the method is based on parameters known to be important in both the performance and quantitative quality of laparoscopy, the results are generalizable to different training platforms and types of laparoscopic surgery.
Full Text Available The Greater Cairo Metropolitan Region (GCMR in its seeking to sustainable development (SD by the year of 2050 facing the serious challenge of around 65 percent of Cairenes live in unplanned settlements. In this respect, the authors examined the effect of urban characteristics of unplanned settlements on SD in the Egyptian context, focusing on the type of unplanned growth on agricultural land. The output of the analysis were fourfold. First of all, we provide a brief overview of previous research on the main types of unplanned settlements in GCMR and the sustainability definition according to the Egyptian context. Secondly, we had a discussion with the local government during our field survey in GCMR to determine the study samples, the main urban characteristics, and the sustainability evaluation criteria in the Egyptian context. Thirdly, through the comparative analysis and geographic information system (GIS, we examined how the character of urban development affected per capita four urban measures in a cross-section of two settlements, one represented the unplanned settlements and other as a comparative planned sample to determine the real gap. Finally, by using the evaluation matrix, the help and block items are estimated for each measure of urban characteristics, providing substantive evidence on how the four measures of urban characteristics have been affected by the urban sprawl.

The present study examined the role of positive outcome expectancy in the relationship between peer/parental influence and Internet gaming addiction (IGA) among adolescents in Taiwan. Two thousand, one hundred and four junior high students completed the Chen Internet Addiction Scale for IGA, Parental Influence for IGA, peer influence for IGA, and Positive Outcome Expectancy of Internet Gaming Questionnaire. Results showed that the three types of peer influences (positive attitudes toward Internet gaming, frequency of Internet game use, and invitation to play) and positive outcome expectancy were significantly and positively correlated with IGA. Moreover, peer influence was also positively correlated with positive outcome expectancy. On the other hand, positive outcome expectancy and parental influences had a low correlation. Structural equation modeling analysis revealed that positive outcome expectancy did not mediate the relationship between either type of parental influences and IGA, and only the parent's invitation to play Internet games directly predicted IGA severity. However, peers' positive attitude or the frequency of peers' Internet game use positively predicted IGA and was fully mediated through positive outcome expectancy of Internet gaming. In addition, the frequency of peers' invitation to play Internet games directly and indirectly predicted IGA severity through a partial mediation of positive outcome expectancy of Internet gaming. The overall fit of the model was adequate and was able to explain 25.0 percent of the variance. The findings provide evidence in illuminating the role of peer influences and positive outcome expectancy of Internet gaming in the process of why adolescents may develop IGA.

In order to clarify the relationship between brain damage and skull asymmetry or supine head position preference, we classified CT findings of 330 cases with cerebral palsy or risk of motor disturbance into 6 groups according to skull shape. Those were severe (I, n = 37) and mild (II, n = 114) grades in the right occipital flatness, severe (III, n = 34) and mild (IV, n = 58) grades in the left occipital flatness, long skull with temporal flatness (V, n = 33) and symmetric round skull (control, n = 54). It was considered that the asymmetry of cortical atrophy in appearance was formed physicaly by skull asymmetry but that the asymmetric dilatation in appearance of lateral ventricle was related to the asymmetry of brain damage. The severity and the asymmetry of brain damage were tend to increase the grade of skull asymmetry. The incidence of cases with the right occipital flatness was 1.6 times more frequently than the left sided. The incidence of cases whose left (lateral) ventricle was larger than the right was 4.1 times more than the cases whose right ventricle was larger than the left. The cases with occipital flatness in the contralateral side of the larger lateral ventricle were found more than the cases with occipital flatness in the ipsilateral side of the larger ventricle, that is to say, the direction of supine head position preference during early infant was suspected to be the more severely disturbed side of body. These results suggest that the supine head position preference to the right in newborn babies and infants with scoliosis or cerebral palsy might be the result of transient or permanent asymmetric (left > right) brain dysfunction.

Conservation of tropical trees can be achieved if supported by the sustainable use of forest by community live nearby through harvesting of non timber woods, for instance rattan. Furthermore, rattan jernang individuals and trees have significant associations. Therefore, objective of this paper is to investigate the utilization of rattan jernang (Deamonorops draco Wild related to the forest tree biodiversity by Anak Dalam tribe in several villages in Jambi, Sumatra. The study has identified that populations of Deamonorops draco were varied among villages, ranged from 40 to 71 clumps in the forests and up to 500 clumps in plantations. Moreover, 73 individual trees consisted of 32 species were identified as rattan host and conserved by the community. Dialium platyespalyum. Quercus elmeri, and Adinandra dumosa were rattan host trees with the highest populations. Meanwhile, a biodiversity of non-host trees consisted of 30 individual trees from 16 species. Interviews revealed that traditional harvesters have acknowledged that trees have significant important ecological roles for the rattan livelihood and therefore it is very important to conserve the forests for the sustainability of harvest in the future. Furthermore, to secure the availability of rattan, the traditional harvesters had started rattan plantation.

We used secondary data analysis to examine associations among aspects of patient-provider relationships and mental and physical health indicators. Positive patient perceptions of patient-provider relationships were associated with fewer mental health symptoms in this outpatient sample of HIV-positive men who have sex with men (N = 171). Regression analyses revealed the role of anxiety and depression in explaining associations between two aspects of patient-provider relationships (i.e. quality of information offered and provider interactional style) and health-related quality of life. The findings demonstrated the importance of patient-provider relationships to improving physical health and functioning and maintaining engagement in care, among HIV-positive men who have sex with men.

This study explored the meaning of a positive client-nurse relationship for seniors with chronic disease receiving in-home care. In this phenomenological study, eight participants aged 65 to 86 were purposefully selected from the Southwest Community Care Access Centre (SW-CCAC) in London, Ontario. Narrative data were collected through audiotaped, in-depth interviews using a semi-structured interview guide. The analysis and interpretation of the interviews revealed that the meaning of a positive client-nurse relationship for these seniors encompassed two patterns of the meaning: having comfort and being connected within this relationship. These two patterns were contextualized by being a senior with chronic disease and were socially constructed through the relational experience of co-creating a positive relationship. Although further research is needed, the insights gained add to what is known about the theory and practice of relational health promotion for seniors living with chronic disease receiving in-home care.

The quality of one's personal relationships has been linked to morbidity and mortality across different diseases. As a result, it is important to examine more integrative mechanisms that might link relationships across diverse physical health outcomes. In this study, we examine associations between relationships and telomeres that predict general disease risk. These questions are pursued in the context of a more comprehensive model of relationships that highlights the importance of jointly considering positive and negative aspects of social ties. One hundred thirty-six individuals from a community sample (ages 48 to 77 years) completed the social relationships index, which allows a determination of relationships that differ in their positive and negative substrates (i.e., ambivalent, supportive, aversive, indifferent). Telomere length was determined from peripheral blood mononuclear cells via quantitative polymerase chain reaction. Participants who had a higher number of ambivalent ties in their social networks evidenced shorter telomeres. These results were independent of other relationship types (e.g., supportive) and standard control variables (e.g., age, health behaviors, and medication use). Gender moderated the links between ambivalent ties and telomere length, with these associations seen primarily in women. Follow-up analyses revealed that the links between ambivalent ties and telomeres were primarily due to friendships, parents, and social acquaintances. Consistent with epidemiological findings, these data highlight a novel and integrative biological mechanism by which social ties may affect health across diseases and further suggest the importance of incorporating positivity and negativity in the study of specific relationships and physical health.

Maternal psychological factors like depression, anxiety and stress have been associated with infant fussiness or colic. However, little research exists on whether positive factors such as social support and the happiness of the mother-partner relationship are associated with lower rates of infant fussiness or colic. We investigated the association between infant colic and three types of maternal support: general maternal social support (during pregnancy and post partum), the happiness of the mother-partner relationship (during pregnancy and post partum) and partner involvement in caring for the newborn. Participants were 3006 women in the First Baby Study, a prospective study of the effect of mode of first delivery on subsequent childbearing. Women were interviewed by telephone during pregnancy and 1 month after first childbirth and asked about social support and if their baby had a variety of problems since birth, including 'Colic - crying or fussiness three or more hours a day'. Multivariable logistic regression models were used to model the association between maternal support and infant colic, controlling for confounders, including maternal race or ethnicity, insurance, marital status, smoking, mode of delivery, maternal post-partum depression, breastfeeding, other neonatal illnesses and newborn gestational age. Infant colic was reported by 11.6% of new mothers. High general maternal social support (in comparison with low), measured during pregnancy, was associated with lower reported infant colic (adjusted odds ratio (AOR), 0.55, 95% confidence interval (CI), 0.40-0.75) and measured post partum (AOR, 0.51, 95% CI, 0.39-0.67); high relationship happiness (in comparison with low), measured during pregnancy (AOR, 0.71, 95% CI, 0.54-0.93), and measured post partum (AOR, 0.22, 95% CI, 0.12-0.40); and high partner involvement with newborn care (in comparison with low) (AOR, 0.60, 95% CI, 0.44-0.81).

The amorphous ferromagnetic glass-coated microwires with positive magnetostriction constant of the metallic core possess the bistable magnetization reversal and the fast domain wall propagation along the microwire axis. These properties and also the magnetization processes in the systems of the microwires are of interest in the magnetic sensing technology, encoding systems and smart composite applications. In this work we present the results of the experimental investigation, simulations and theoretical estimations of the hysteresis process in the systems of the magnetically bistable microwires with different length and positional relationship between them. The location of the short microwires near the long microwire affects the switching fields (external coaxial magnetic field applied for starting of the domain wall propagation along the microwire axis) and the hysteresis process. The changes of these properties are not directly proportional to the value of the shorter microwire shift along the longer one. When the short microwire was placed in the middle of the long one and when the one end of the long microwire coincided with the end of the short one, the two-steps hysteresis loops were observed for both sample orientations: before and after sample rotation on 180 Degree-Sign . When the short microwire was placed close to the end of the long microwire (but did not coincide with it) we observed at first the two-steps hysteresis loop and single step behavior for one branch of the hysteresis loop after sample rotation. Moreover, changing of the orientation of the samples results in the shift of the switching field of the shorter microwire when its end was located near the end or coincided with the end of the longer one. This uncommon hysteresis behavior was explained and illustrated using results of the simulations. The values of microwires interaction were also estimated.

To provide diagnostic information by evaluation of the positional relationship between the mandibular third molar and the mandibular canal. Eighty-nine mandibular third molars were classified as mesioangular, horizontal, vertical, distoangular groups. The distances between the mandibular third molar and the mandibular canal were measured in cone-beam computed tomographs. The height and width ratios of distances from the mandibular third molar and the mandibular canal to the mandibular inferior border and to the lingual cortical plate were calculated. The vertical and buccolingual distances between the mandibular third molar and the mandibular canal were 0.03 mm, 2.96 mm in the mesioangular, 0.37 mm, 3.38 ,, in the horizontal, -1.50 mm, 1.38 mm in the vertical, -1.10 mm, 4.20 mm in the distoangular group. There were significant differences in vertical (P<0.05), but not in buccolingual (P>0.05). The height and width ratios of distances on the mandibular third molar were 47.1%, 36.1% in the mesioangular, 47.4%, 34.4% in the horizontal, 37.0%, 46.7% in the vertical, 40.9%, 37.4% in the distoangular group. There were significant differences between the mesioangular and the vertical group, and the horizontal and the vertical group in height ratio (P>0.05). The mesioangular group showed the nearest distance between the mandibular third molar and the mandibular canal vertically. The root apex of the mandibular third molar was positioned more buccally in the vertical group than in the mesioangular group.

Over half of globally threatened animal species have experienced rapid geographic range loss. Identifying the parts of species' distributions most vulnerable to local extinction would benefit conservation planning. However, previous studies give little consensus on whether ranges decline to the core or edge. We built on previous work by using empirical data to examine the position of recent local extinctions within species' geographic ranges, address range position as a continuum, and explore the influence of environmental factors. We aggregated point-locality data for 125 Galliform species from across the Palearctic and Indo-Malaya into equal-area half-degree grid cells and used a multispecies dynamic Bayesian occupancy model to estimate rates of local extinctions. Our model provides a novel approach to identify loss of populations from within species ranges. We investigated the relationship between extinction rates and distance from range edge by examining whether patterns were consistent across biogeographic realm and different categories of land use. In the Palearctic, local extinctions occurred closer to the range edge than range core in both unconverted and human-dominated landscapes. In Indo-Malaya, no pattern was found for unconverted landscapes, but in human-dominated landscapes extinctions tended to occur closer to the core than the edge. Our results suggest that local and regional factors override general spatial patterns of recent local extinction within species' ranges and highlight the difficulty of predicting the parts of a species' distribution most vulnerable to threat. © 2017 The Authors.

Metabolic health and positive symptom severity has been investigated in schizophrenia, but not in clinical high risk (CHR) patients. We hypothesized that greater body mass index (BMI) in CHR patients would be related to less positive symptoms. We examined this relationship in CHR patients being treated with 1) no psychotropic medications (n = 58), 2) an antipsychotic (n = 14), or 3) an antidepressant without an antipsychotic (n = 10). We found no relationship between BMI and positive symptoms in unmedicated CHR patients, the majority of whom had a narrow BMI range between 20 and 30. However, in the smaller sample of CHR patients taking an antidepressant or antipsychotic, BMI was negatively correlated with positive symptoms. Although potentially underpowered, these preliminary findings provide initial steps in elucidating the relationships between metabolic health, neurochemistry, and symptom severity in CHR patients.

Sustainable diets, as defined by the Food and Agriculture Organization, need to combine environment, nutrition, and affordability dimensions. However, it is unknown whether these dimensions are compatible, and no guidance is available in the official recommendations. To identify foods with compatible sustainability dimensions. For 363 of the most commonly consumed foods in the Second French Individual and National Study on Food Consumption, environmental impact indicators (ie, greenhouse gas [GHG] emissions, acidification, and eutrophication), and prices were collected. The nutritional quality of the foods was assessed by calculating the score for the nutritional adequacy of individual foods (SAIN) to score for disqualifying nutrients (LIM) ratio. A sustainability score based on the median GHG emissions, price, and SAIN:LIM was calculated for each food; the foods with the best values for all three variables received the highest score. The environmental indicators were strongly and positively correlated. Meat, fish, and eggs and dairy products had the strongest influence on the environment; starchy foods, legumes, and fruits and vegetables had the least influence. GHG emissions were inversely correlated with SAIN:LIM (r=-0.37) and positively correlated with price per kilogram (r=0.59); the correlation with price per kilocalorie was null. This showed that foods with a heavy environmental impact tend to have lower nutritional quality and a higher price per kilogram but not a lower price per kilocalorie. Using price per kilogram, 94 foods had a maximum sustainability score, including most plant-based foods and excluding all foods with animal ingredients except milk, yogurt, and soups. Using price per kilocalorie restricted the list to 42 foods, including 52% of all starchy foods and legumes but only 11% of fruits and vegetables (mainly 100% fruit juices). Overall, the sustainability dimensions seemed to be compatible when considering price per kilogram of food. However
Over one-third of Earth is classified as arid or semi-arid which includes a variety of water-limited environments such as savannas, deserts, and Mediterranean grasslands and steppes. Within these environments, water is often considered the resource limiting plant growth as well as ecosystem productivity and diversity. Plant community structure and the spacing distance between individuals is driven by simultaneously occurring positive and negative plant-plant interactions. Plants often interact negatively through direct competition of resources (i.e. water, light, nutrients) and positively via microclimatic amelioration which helps reduce the abiotic stress of other nearby plants. Classically, ecologists concentrate on the impacts of plant-plant interactions by monitoring plant performance (e.g. density, survival, biomass accumulation) in the context of the larger vegetative community. The objective of this research is to fill fundamental knowledge gaps regarding how individual plants interact with each other for limited resources in water limited environments under sustained unidirectional winds to improve our understanding of how climate and land-use change will effect the hydrodynamics of plant communities. Rather than adopting traditional approaches, we focus on the hydrodynamics of plant-plant interactions through physical experimentation and numerical simulation. Experiments were performed in a unique low-velocity climate-controlled wind tunnel interfaced with a synthetic aquifer, both of which are outfitted with current state-of-art sensor technology; synthetic plants were used in lieu of living vegetation to reduce experimental complexity as demonstrated in Trautz et al. . Results demonstrate that there exist complex feedbacks and interactions between the bulk soil, atmosphere, and plant canopies and root zones that play key roles in controlling soil moisture dynamics. The presence of two plants led to improved soil moisture conservation compared to

Peer acceptance and friendships were examined as moderators in the link between family adversity and child externalizing behavioral problems. Data on family adversity (i.e., ecological disadvantage, violent marital conflict, and harsh discipline) and child temperament and social information processing were collected during home visits from 585 families with 5-year-old children. Children's peer acceptance, friendship, and friends' aggressiveness were assessed with sociometric methods in kindergarten and grade 1. Teachers provided ratings of children's externalizing behavior problems in grade 2. Peer acceptance served as a moderator for all three measures of family adversity, and friendship served as a moderator for harsh discipline. Examination of regression slopes indicated that family adversity was not significantly associated with child externalizing behavior at high levels of positive peer relationships. These moderating effects generally were not qualified by child gender, ethnicity, or friends' aggressiveness, nor were they accounted for by child temperament or social information-processing patterns. The need for process-oriented studies of risk and protective factors is stressed. PMID:12146744
Support for authoritarian approaches to parenting, including corporal punishment, is known to be elevated among individuals with low current levels of socioeconomic attainment. The objectives of this study are: (1) to determine whether authoritarian parenting dispositions are related to disadvantages in one's social background, in addition to one's present socioeconomic standing; and (2) to distinguish, in this regard, between support for spanking and other authoritarian parenting dispositions. Ordered logit models, applied to General Social Survey data concerning a nationally representative sample of US adults, are used to examine relationships of authoritarian parenting dispositions to the socioeconomic positions that respondents currently occupy and in which they were raised. It is found that support for spanking (N=10,725) and valuing of obedience (N=10,043) are inversely related to the socioeconomic status (SES) of one's family of origin, and that these associations are robust to controls for one's current SES. A disadvantaged family background is found to increase support for spanking most among those with high current SES. Strong associations (robust to controls for SES indicators) are additionally found between African-American racial identity and support for authoritarian parenting. Prior research indicates that authoritarian parenting practices such as spanking may be harmful to children. Thus, if the parenting attitudes analyzed here translate into parenting practices, then this study's findings may point to a mechanism for the intergenerational transmission of disadvantages.

That separation and divorce frequently burden the young child emotionally and developmentally has moved from scientific to common knowledge over the past two decades. Recent cultural changes also moderate or intensify such stress and strain on the parent-child relationship: a divorce rate hovering at about 40% of all marriages, a third of all…

Using cross-sectional data collected in rural communities of two provinces of China, this study examined the protective role of perceived positive teacher-student relationship for Chinese left-behind children. The participants included 1442 children with a mean age of 14.13 classified into two groups: a left-behind group (104 boys and 110 girls) and a comparison group (588 boys and 640 girls). Self-reported questionnaires concerning self-esteem, depression, problem behaviours and the teacher-student relationship were administered. Relative to the comparison group, after controlling for age, gender and family socioeconomic status, the left-behind group was disadvantaged in terms of self-esteem and depression but not in problem behaviours. As hypothesised, the results of regression analyses indicated that teacher-student relationship positively predicted self-esteem and negatively predicted depression and problem behaviours for both groups. Moreover, the association between teacher-student relationship and depression was stronger among the left-behind group, suggesting that left-behind children were more responsive to the positive effect of a desired teacher-student relationship. Taken together, the results of our study support the idea that perceived positive teacher-student relationship may serve as a protective factor for left-behind children. Practical implications and limitations of the present study are discussed. © 2014 International Union of Psychological Science.

Institutional caregiving is associated with significant deviations from species-expected caregiving, altering the normative sequence of attachment formation and placing children at risk for long-term emotional difficulties. However, little is known about factors that can promote resilience following early institutional caregiving. In the current study, we investigated how adaptations in affective processing (i.e., positive valence bias) and family-level protective factors (i.e., secure parent-child relationships) moderate risk for internalizing symptoms in previously institutionalized (PI) youth. Children and adolescents with and without a history of institutional care performed a laboratory-based affective processing task and self-reported measures of parent-child relationship security. PI youth were more likely than comparison youth to show positive valence biases when interpreting ambiguous facial expressions. Both positive valence bias and parent-child relationship security moderated the association between institutional care and parent-reported internalizing symptoms, such that greater positive valence bias and more secure parent-child relationships predicted fewer symptoms in PI youth. However, when both factors were tested concurrently, parent-child relationship security more strongly moderated the link between PI status and internalizing symptoms. These findings suggest that both individual-level adaptations in affective processing and family-level factors of secure parent-child relationships may ameliorate risk for internalizing psychopathology following early institutional caregiving.

Background/aim: This study aimed to evaluate the relationship between the Trendelenburg position and cerebral hypoxia in robot-assisted hysterectomy and prostatectomy.Materials and methods: A standardized mini-mental state examination was administered to 50 patients enrolled in the study 1 h before and after surgery. Near infrared spectroscopy (NIRS) values and hemodynamic and respiratory parameters were recorded after induction of anesthesia (baseline) and once every 20 min in the Trendelenburg position and supine positions. The relationship between the development of cerebral desaturation and the patient's position was examined. Results: For all patients, the baseline mean cerebral oxygen saturation (RSO2) on the right and left were 70.5 ± 7.3% and 70.6 ± 6.7%, respectively. Right RSO2 values at 20 min and 60 min in the Trendelenburg position decreased significantly, but they increased at 120 min. A significant positive correlation was found between right RSO2 and EtCO2 in the supine period following surgery, and between left RSO2 and EtCO2 at 60 min in the Trendelenburg and supine positions. The relationship between NIRS values and cognitive dysfunction was not significant.Conclusion: We found that cerebral saturation decreases as age increases, and cerebral desaturation may occur owing to the Trendelenburg position. There was no correlation between patients? cognitive function and NIRS values.

To investigate whether the impact of negative and positive social exchanges on depression depends on relationship type among late middle age and older adults. Using data from the English Longitudinal Study of Aging, baseline positive and negative exchanges with partners, children, other family and friends were linked to 2-year changes in depression on the eight-item Center for Epidemiologic Studies Depression Scale. Positive and negative exchanges with partners and with children were independently associated with depression, adjusting for age, gender, wealth, and baseline depression. Negative but not positive exchanges with other family and with friends were associated with depression. The association between depression and positive/negative exchanges was weaker among the above 70s compared with those aged 50 to 70. Negative and positive exchanges with partners and children appear equally salient for depression onset although negative exchanges with family and friends contribute to depression whereas positive exchanges do not.

Gastric cancer (GC) is a typical type of inflammation-related tumor. The p42.3 gene is shown to be highly expressed in GC, but its association with gastritis remains unknown. We aimed to explore the relationship between gastric inflammation and p42.3 gene in vitro and in vivo. Normal gastric epithelial cells (GES-1) were treated with Helicobacter pylori (H. pylori) and tumor necrosis factor (TNF)-α. Total cell mRNA and protein were extracted and collected, and polymerase chain reaction and Western blot were performed to determine the relative expression of p42.3 gene. In total, 291 biopsy samples from patients with chronic non-atrophic gastritis were collected and immunohistochemistry was used to measure the p42.3 protein expression. The association between p42.3 protein expression and the clinicopathological characteristics of these patients were analyzed. Both H. pylori and TNF-α significantly enhanced the p42.3 protein expression in GES-1 cells in a time and dose-dependent manner. In addition, p42.3 gene expression was positively associated with the severity of gastric mucosal inflammation and H. pylori infection (P = 0.000). Its expression was significantly more common in severe gastric inflammation and in H. pylori-infected cases. p42.3 gene expression is associated with gastric mucosal inflammation that can be upregulated by TNF-α and H. pylori infection. © 2015 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

The objective of this study is to assess the relationship between centric relation-intercuspal position discrepancy (CR-ICP discrepancy) and temporomandibular disorders (TMDs), by systematically reviewing the literature. A systematic research was performed between 1960 and 2016 based on electronic databases: PubMed, Cochrane Library, Medline, Embase, Scopus, EBSCOhost, BIREME, Lilacs and Scielo, including all languages. Analytical observational clinical studies were identified. Two independent authors selected the articles. PICO format was used to analyze the studies. The Newcastle-Ottawa Scale (NOS) was used to verify the quality of the evidence. Four hundred and sixty-seven potentially eligible articles were identified. Twenty studies were analyzed, being grouped according to intervention in studies in orthodontic patients (n = 3) and studies in subjects without intervention (n = 17). Quality of evidence was low, with an average score of 3.36 according to Newcastle-Ottawa Scale. In most studies, the presence of CR-ICP discrepancy is associated with the presence of muscle (pain) and joint disorders (noise, disc displacement, pain, crepitus, osteoarthritis and osteoarthrosis). However, the lack of consistency of the results reported reduces the validity of the studies making it impossible to draw any definite conclusions. Because of the heterogeneity of the design and methodology and the low quality of the articles reviewed, it is not possible to establish an association between CR-ICP discrepancy and TMD. The consequence of CR-ICP discrepancy on the presence of TMD requires further research, well-defined and validated diagnostic criteria and rigorous scientific methodologies. Longitudinal studies are needed to identify CR-ICP discrepancy as a possible risk factor for the presence of TMD.

Both diet quality and socioeconomic position (SEP) have been linked to age-related cognitive changes, but there is little understanding of how the socioeconomic context of dietary intake may shape its cognitive impact. We examined whether equal adherence to "prudent" and "Western" dietary patterns, identified by principal components analysis, was associated with global cognitive function [Modified Mini-Mental State Examination (3MS)] in independently living older adults with different SEPs (aged 68-84 y; n = 1099). The interaction of dietary pattern adherence with household income, educational attainment, occupational prestige, and a composite indicator of SEP combining all 3 was examined in multiple-adjusted mixed models over 3 y of follow-up in participants of the NuAge study (Quebec Longitudinal Study on Nutrition and Successful Aging). Adherence to the prudent pattern (vegetables, fruits, fish, poultry, and lower-fat dairy products) was related to higher 3MS scores at recruitment only in the upper categories of income [parameter estimate (B): 0.56; 95% CI: 0.11, 1.01], education (B: 0.44; 95% CI: 0.080, 0.80), or composite SEP (B: 0.37; 95% CI: 0.045, 0.70). High prudent pattern adherence was associated with less cognitive decline only in those with low composite SEP (B: 0.25; 95% CI: 0.0094, 0.50). Conversely, adherence to the Western pattern (meats, potatoes, processed foods, and higher-fat dairy products) was associated with more cognitive decline (B: -0.23; 95% CI: -0.43, -0.032) only in those with low educational attainment. In summary, among individuals with equivalent diet quality, the magnitude and characteristics of the diet-cognition relationship depended on their socioeconomic circumstances. These results suggest that interventions promoting retention of cognitive function through improved diet quality would provide maximum benefit to those with relatively low SEP.
Full Text Available Taking education outside of the classroom is an exciting, yet daunting, proposition. Community-based education can provide students exposure to the richness and complication of the world outside of academe—the people, politics and interconnections that both challenge and complement our traditional modes of teaching. These educational experiences also play many other important roles within the institution, reinforcing the mission, providing relevance within the communities the institution serves, and fulfilling the citizenship roles many colleges and universities value. This paper uses experiences and insights gained planning and staffing an annual community arts festival to develop a model of campus-community partnership that is based on a broad conception of reciprocity. Incorporating the perspectives of a faculty member, a student, a college administrator and a community partner, the paper describes the process by which the project, and an associated course, have been (and continue to be developed. We argue that applying the broader concepts of reciprocity enhance the success, sustainability and satisfaction of working in partnership.
Positive Psychology Interventions Addressing Pleasure, Engagement, Meaning, Positive Relationships, and Accomplishment Increase Well-Being and Ameliorate Depressive Symptoms: A Randomized, Placebo-Controlled Online Study
Gander, Fabian; Proyer, René T.; Ruch, Willibald
Seligman (2002) suggested three paths to well-being, the pursuit of pleasure, the pursuit of meaning, and the pursuit of engagement, later adding two more, positive relationships and accomplishment, in his 2011 version. The contribution of these new components to well-being has yet to be addressed. In an online positive psychology intervention study, we randomly assigned 1624 adults aged 18–78 (M = 46.13; 79.2% women) to seven conditions. Participants wrote down three things they related to either one of the five components of Seligman's Well-Being theory (Conditions 1–5), all of the five components (Condition 6) or early childhood memories (placebo control condition). We assessed happiness (AHI) and depression (CES-D) before and after the intervention, and 1-, 3-, and 6 months afterwards. Additionally, we considered moderation effects of well-being levels at baseline. Results confirmed that all interventions were effective in increasing happiness and most ameliorated depressive symptoms. The interventions worked best for those in the middle-range of the well-being continuum. We conclude that interventions based on pleasure, engagement, meaning, positive relationships, and accomplishment are effective strategies for increasing well-being and ameliorating depressive symptoms and that positive psychology interventions are most effective for those people in the middle range of the well-being continuum.

However, little is known about how such deficits affect functional outcomes. The purpose of this study was to investigate the relationship between social cognition and functional outcomes in patients with TBI. We studied this relationship in 20 patients with TBI over the course of 1 year post-injury. Patients completed neurocognitive assessments and social cognition tasks. The social cognition tasks included an emotion-perception task and three theory of mind tasks: the Faux Pas test, Reading the Mind in the Eyes (Eyes test, and the Moving-Shapes paradigm. The Craig Handicap Assessment and Reporting Technique was used to assess functional outcomes. Compared with our database of normal subjects, patients showed impairments in all social cognition tasks. Multiple regression analysis revealed that theory of mind ability as measured by the Eyes test was the best predictor of the cognitive aspects of functional outcomes. The findings of this pilot study suggest that the degree to which a patient can predict what others are thinking is an important measure that can estimate functional outcomes over 1 year following TBI.

Inequality within partner relationships is associated with HIV acquisition and gender violence, but little is known about more pervasive effects on women's health. We performed a cross-sectional analysis of associations between sexual relationship power and nutritional status among women in Uganda. Participants completed questionnaires and anthropometric measurements. We assessed sexual relationship power using the Sexual Relationship Power Scale (SRPS). We performed logistic regression to test for associations between sexual relationship power and poor nutritional status including body mass index, body fat percentage, and mid-upper arm circumference. Women with higher sexual relationship power scores had decreased odds of low body mass index (OR 0.29, p = 0.01), low body fat percentage (OR 0.54, p = 0.04), and low mid-upper arm circumference (OR 0.22, p = 0.01). These relationships persisted in multivariable models adjusted for potential confounders. Targeted interventions to improve intimate partner relationship equality should be explored to improve health status among women living with HIV in rural Africa.

Research on meaning in life has generally focused on global meaning judgments. This study examined how people's daily experiences, represented by events that occur in daily life, influence their perceived sense of meaning on a daily basis. One hundred sixty-two college students completed daily reports for 2 weeks. We examined the relationships among daily social and achievement events, daily positive and negative affect, and daily meaning in life. In addition, we tested the possible moderating influence of depressive symptoms on these relationships. Positive daily social and achievement events were related to greater daily meaning, above and beyond the contributions of daily positive and negative affect. Negative social and achievement events were related to less daily meaning, and negative achievement events covaried with daily meaning above and beyond positive and negative affect. Depression moderated the relationships between positive events and meaning, such that people who reported more depressive symptoms had greater increases in daily meaning in response to positive social and achievement events than individuals who reported fewer symptoms. These findings suggest the important role that daily events may play in fluctuations in people's affective experiences and sense of meaning in life. © 2014 Wiley Periodicals, Inc.

The Sustainable Development Goals (SDGs) are a good example of the increasing demand on our soil resources. Our soil resources play a central role in multiple SDGs while talking about poverty (SDG 1), food security (SDG 2), clean energy through biofuels (SDG 7), climate mitigation (SDG 13), and land degradation (SDG 15). This means that basic decisions on soil management are now placed in the context of multiple soil functions. A good example is the global production of bananas and plantains with a total harvested area of almost 10 million ha. While the export bananas played a central role in economic development, an even larger share of the production plays a role in food security. Nevertheless, the production is also criticized due the intensive use of agricultural chemicals (fertilizers and pesticides) and the risk of soil degradation in the monoculture plantations. Decisions on soil management are context specific and depending on the environment. In this study we will analyse and discuss three production environments from the Philippines, Uganda, and Costa Rica. The role of the SDGs in the regions is very different. Where SDG 1 and SDG15 play an important role in the Costa Rican situation, SDG 2 is more important in Uganda and the Philippines. Decisions on soil management strongly depend on the agro-ecology with the available technological packages. The technological packages include low external input farming, organic farming, precision agriculture, and so-called best management practices. While producers take decisions at the field and farm level, we are now increasingly forced for joined action at the regional level with the rapid spread of highly virulent crop diseases. The SDGs have major consequences for soil management but this study shows that, at the same time, they cannot be translated one-to-one to the farm level at which the management decisions are taken. Therefore, off-farm effects and externalities are often not considered in farm management
Full Text Available Earthworms are a major component of soil fauna communities. They influence soil chemical, biological, and physical processes and vice versa, their abundance and diversity are influenced by natural characteristics or land management practices. There is need to establish their characteristics and relations. In this study earthworm density (ED, body biomass (EB, and diversity in relation to land use (arable land—AL, permanent grasslands—PG, management, and selected abiotic (soil chemical, physical, climate related and biotic (arthropod density and biomass, ground beetle density, carabid density indicators were analysed at seven different study sites in Slovakia. On average, the density of earthworms was nearly twice as high in PG compared to AL. Among five soil types used as arable land, Fluvisols created the most suitable conditions for earthworm abundance and biomass. We recorded a significant correlation between ED, EB and soil moisture in arable land. In permanent grasslands, the main climate related factor was soil temperature. Relationships between earthworms and some chemical properties (pH, available nutrients were observed only in arable land. Our findings indicate trophic interaction between earthworms and carabids in organically managed arable land. Comprehensive assessment of observed relationships can help in earthworm management to achieve sustainable agricultural systems.

Research aims The present article provides a comprehensive examination of the relationship between playing position and leadership in sport. More particularly, it explores links between leadership and a player’s interactional centrality—defined as the degree to which their playing position provides opportunities for interaction with other team members. This article examines this relationship across different leadership roles, team sex, and performance levels. Results Study 1 (N = 4443) shows that athlete leaders (and the task and motivational leader in particular) are more likely than other team members to occupy interactionally central positions in a team. Players with high interactional centrality were also perceived to be better leaders than those with low interactional centrality. Study 2 (N = 308) established this link for leadership in general, while Study 3 (N = 267) and Study 4 (N = 776) revealed that the same was true for task, motivational, and external leadership. This relationship is attenuated in sports where an interactionally central position confers limited interactional advantages. In other words, the observed patterns were strongest in sports that are played on a large field with relatively fixed positions (e.g., soccer), while being weaker in sports that are played on a smaller field where players switch positions dynamically (e.g., basketball, ice hockey). Beyond this, the pattern is broadly consistent across different sports, different sexes, and different levels of skill. Conclusions The observed patterns are consistent with the idea that positions that are interactionally central afford players greater opportunities to do leadership—either through communication or through action. Significantly too, they also provide a basis for them to be seen to do leadership by others on their team. Thus while it is often stated that “leadership is an action, not a position,” it is nevertheless the case that, when it comes to performing that

Individuals with social anxiety disorder (SAD) have difficulty forming social relationships. The prevailing clinical perspective is that negative emotions such as anxiety inhibit one's capacity to develop satisfying social connections. However, empirical findings from social psychology and affective neuroscience suggest that positive emotional experiences are fundamental to establishing new social bonds. To reconcile these perspectives, we collected repeated measurements of anxiety, positive emotions (pleasantness), and connectedness over the course of a controlled relationship formation encounter in 56 participants diagnosed with SAD (64% female; M age =23.3, SD=4.7). Participants experienced both increases in positive emotions and decreases in anxiety throughout the interaction. Change in positive emotions was the most robust predictor of subsequent increases in connectedness, as well as a greater desire to engage one's partner in future social activities, above and beyond reductions in anxiety (medium to large sized effects). Those findings suggest that anxiety-based models alone may not fully explain difficulties in relationship formation in SAD, and underscore the potential value of considering positive emotional experiences in conceptual and treatment models of SAD.

Full Text Available Background. Presumably, the academic stress that builds throughout the academic year has a negative effect on dental students’ psychological well-being and may have a relationship with academic performance. This research aimed to analyse the variation of positive well-being in second-year dental students, across the academic semester, in relation to consecutive examinations as part of academic assessment system (1 and to observe the relationship between academic performance during semester evaluation period and dental students’ positive well-being (2. Methods. A prospective study was conducted on second-year dental students, data on positive well-being being collected with WHO-Five Well-Being Index (WHO-5, at the beginning of the semester and after three consecutive mandatory examinations. Results. One hundred and forty-six dental students were included (77% response rate. Repeated ANOVA showed a significant progressive decline of positive well-being over the semester, which was clinically significant for an important part of them. Students who performed better in the semester evaluation period registered higher well-being levels at the beginning of the semester but a more pronounced decline of it until the semester evaluation period. Conclusion. Based on this research, a relationship between positive well-being, academic assessments, and academic performance is suggested, when evaluating them in a prospective frame.

Full Text Available Patients with Attention-Deficit/Hyperactivity Disorder (ADHD and obsessive/compulsive disorder (OCD share problems with sustained attention, and are proposed to share deficits in switching between default mode and task positive networks. The aim of this study was to investigate shared and disorder-specific brain activation abnormalities during sustained attention in the two disorders. Twenty boys with ADHD, 20 boys with OCD and 20 age-matched healthy controls aged between 12 and 18 years completed a functional magnetic resonance imaging (fMRI version of a parametrically modulated sustained attention task with a progressively increasing sustained attention load. Performance and brain activation were compared between groups. Only ADHD patients were impaired in performance. Group by sustained attention load interaction effects showed that OCD patients had disorder-specific middle anterior cingulate underactivation relative to controls and ADHD patients, while ADHD patients showed disorder-specific underactivation in left dorsolateral prefrontal cortex/dorsal inferior frontal gyrus (IFG. ADHD and OCD patients shared left insula/ventral IFG underactivation and increased activation in posterior default mode network relative to controls, but had disorder-specific overactivation in anterior default mode regions, in dorsal anterior cingulate for ADHD and in anterior ventromedial prefrontal cortex for OCD. In sum, ADHD and OCD patients showed mostly disorder-specific patterns of brain abnormalities in both task positive salience/ventral attention networks with lateral frontal deficits in ADHD and middle ACC deficits in OCD, as well as in their deactivation patterns in medial frontal DMN regions. The findings suggest that attention performance in the two disorders is underpinned by disorder-specific activation patterns.

Global competition in the automotive industry has encouraged companies to implement quality management practices in all managerial aspects to ensure customer satisfaction in products and reduce costs. Therefore, guaranteeing only product quality is insufficient without considering product sustainability, which involves economic, environment, and social elements. Companies that meet both objectives gain advantages in the modern business environment. This study addresses the issues regarding product quality and sustainability in small and medium-sized enterprises in the Malaysian automotive industry. A research was carried out in 91 SMEs automotive suppliers in throughout Malaysia. The analyzed using SPSS ver.23 has been proposed in correlation study. Specifically, this study investigates the relationship between quality management practices and organizational performance as well as the mediating effect of sustainable product development on this relationship.

Bowlby's attachment intergenerational transmission theory suggests that a woman's attachment to her parents, particularly her mother, plays an important role in her future parenting. We studied whether there was any association between pregnant women's attachment to their baby before and after birth and their relationships with their mothers. A longitudinal study was carried out in 2015 on 201 first-time mothers recruited in the maternity ward of the level two Misericordia e Dolce Hospital in Prato, Italy. At 32 weeks of pregnancy, the women filled in the Parental Bonding Instrument and the Prenatal Attachment Inventory and their spontaneous attachment behaviour towards their newborn infants was observed in the nursery during the first two days after childbirth. Having a good relationship with their own mothers was a positive predictor for the women's prenatal attachment to their baby and caregiving and attachment behaviour to their newborn infants. In addition, the mothers' prenatal attachment positively predicted their behavioural attachment pattern after birth. We found that women who had positive relationships with their own mothers also had positive attachments to their unborn babies and in the period immediately after birth. Our findings supported Bowlby attachment intergenerational transmission theory. This article is protected by copyright. All rights reserved. This article is protected by copyright.

Full Text Available Positioning technologies such as GPS enable mobile map applications to display a symbol representing an estimation of a user’s location on a mobile map, therefore acting as a positioning aid. Previous research on the cognitive processes involved in map reading suggests that map readers need at least two map–environment points (objects that are visualized on the map and perceived in the environment for determining their location on a map. Hence, the positioning aid alone does not provide enough information for self-location. Using a field experiment, we assessed the effect of representing the user’s location on a map on the cognitive processes involved in self-location. The results show that positioning aids guide the search for map–environment points and narrow the area on the map that must be scanned for self-location.

Full Text Available The present study was conducted in Mollaahmad watershed of Ardabil city in 1390 to evaluate the canonical correlation between tillage erosion [slope gradient and position], and grain yield and barley yield components (Sahand cultivar in order to determine the covariability between the two sets of variables to (1 detect simultaneously occurring patterns in the interdependencies sets of canonical variables, and (2 to prepare the possibility of canonical correlation coefficient use in a predictive mode for the variation of barely yield. For this purpose plant sampling was done from dry farming land of three landscapes and from four slope positions. The findings of canonical correlation analysis indicated that there are optimal linear combinations between sets of canonical variables of slope gradient and position and barely yield components that the amount of this correlation is identified by 77 percent. According to this correlation, when the slope gradient increases with 28 percent and slope position changes from down to up slope with 96 percent, the dry matter by 8 percent, spike number by 1.1 percent and grain yield by 22 percent will decrease, and the spike weight by 2.12 percent and 1000 grain weight by 14 percent will increase that spike weight and slope position had the largest role in the forming of first canonical correlation coefficient compared to other canonical variants. Using this test, which distinguishes the importance and the role of soil erosion variants in barley yield, high prediction of spike weight by slope position is clear also slope position as a part of soil erosion indices has no similar worth toward slope gradient and the differences are dramatic. Whereas, slope position effect on crop yield is evaluated differently from slope gradient. genotypes.

This study examined the effects of Pathways Triple P (PTP), an early intervention program designed to promote positive parent-child relationships. Sixty parents met the inclusion criteria of borderline to clinically significant relationship disturbance and child emotional and behavioral problems. They were randomly allocated into PTP or a wait-list (WL) control group. PTP was delivered in a group format for 9 weeks and consisted of parent skills training and cognitive behavior therapy targeting negative attributions for child behavior. Significant intervention effects were found for improving parent-child relationships and reducing behavior problems with gains maintained at 3-month follow-up. Limitations of the study and implications for future research are discussed.

The current study examined the role of adolescents' self-regulation as a mediator between sibling relationship quality and adolescent outcomes, after controlling for the quality of the parent-child relationship. Participants were 395 families (282 two parent; 113 single parent) with an adolescent child (M age of child at Time 1 = 11.15, SD = .96, 49% female) who took part in [project name masked for blind review] at both Time 1 and Time 2. Path analysis via structural equation modeling suggested that sibling affection was longitudinally and positively related to self-regulation and prosocial behaviors, and negatively related to externalizing behaviors; while sibling hostility was positively, and having a sister was negatively related to internalizing behaviors (in general, paths were stronger for adolescents from two- vs. single-parent families). There was also evidence that adolescents' self-regulation partially mediated the relation between sibling affection and positive and negative adolescent outcomes. The discussion focuses on the importance of continued research examining the mechanisms through which the sibling relationship influences development during adolescence.

Perception of limb and body positions is known as proprioception. Sensory feedback, especially from proprioceptive receptors, is essential for motor control. Aging is associated with a decline in position sense at proximal joints, but there is inconclusive evidence of distal joints being equally affected by aging. In addition, there is initial evidence that physical activity attenuates age-related decline in proprioception. Our objectives were, first, to establish wrist proprioceptive acuity in a large group of seniors and compare their perception to young adults, and second, to determine if specific types of training or regular physical activity are associated with preserved wrist proprioception. We recruited community-dwelling seniors (n = 107, mean age, 70 ± 5 years, range, 65-84 years) without cognitive decline (Mini Mental State Examination-brief version ≥13/16) and young adult students (n = 51, mean age, 20 ± 1 years, range, 19-26 years). Participants performed contralateral and ipsilateral wrist position sense matching tasks with a bimanual wrist manipulandum to a 15° flexion reference position. Systematic error or proprioceptive bias was computed as the mean difference between matched and reference position. The respective standard deviation over five trials constituted a measure of random error or proprioceptive precision. Current levels of physical activity and previous sport, musical, or dance training were obtained through a questionnaire. We employed longitudinal mixed effects linear models to calculate the effects of trial number, sex, type of matching task and age on wrist proprioceptive bias and precision. The main results were that relative proprioceptive bias was greater in older when compared to young adults (mean difference: 36% ipsilateral, 88% contralateral, p physical activity levels did not affect bias or precision. Our findings demonstrate that aging is associated with a decline in proprioceptive bias in distal arm joints, but age does
Full Text Available The cultural heritage, including, according to the UNESCO definition, the assembly of monuments, groups of buildings, and sites which are of outstanding universal value from the historical, aesthetic, ethnological or anthropological point of view, represents an important asset that can be engaged and capitalized in order to support the sustainable development. Meeting the needs of the present without compromising the ability of the future generations to meet their own needs in order to provide a better quality of life for everyone, now and for generations to come, has become a concern and, in the same time, a priority for all the stakeholders of the society. Turning to the best account of the cultural heritage also represents an important driver for the sustainable development of the travel and tourism industry, as the cultural sites, institutions, goods and services, appropriately capitalized, represent significant attractions for the international and domestic tourists. The integration of the principles of sustainable development in the current functioning of the travel and tourism industry led to the development and implementation of the concept of sustainable tourism. The paper explores in a distinctive manner the relationships between the cultural heritage and the travel and tourism industry, respectively the cultural heritage and the sustainable development based on a set of related statistical indicators, and the specific secondary data, expressing the extent of the cultural heritage, the development of the travel and tourism industry, and the attained level of sustainable development in ten Central and Eastern European countries, members of the European Union. There are two major research questions the paper aims to answer: (1 How significant is the relationship between the cultural heritage and the development of the travel and tourism industry? (2 Is there a noteworthy connection between the cultural heritage and the sustainable

Primary effusion lymphoma (PEL) is one of the least common of the AIDS-related lymphomas, accounting for less than 1–4% of cases. Clinical manifestations depend on the extent and distribution of disease and, as in the majority of patients no detectable mass lesion is found, symptoms are related to fluid accumulation, dyspnoea (pleural or pericardial effusions), abdominal distension (ascites) or joint swelling. The median survival after diagnosis, even with aggressive chemotherapy, remains poor and remissions are often of short duration. We present the case of a 31-year-old man with AIDS and diagnosis of PEL, in whom sustained and complete remission of the tumour was achieved with adjunctive ganciclovir therapy. Since the disease is so uncommon, there is a paucity of data to guide the treatment of these patients; ganciclovir might be a potential antiviral therapeutic option, as demonstrated by the 2-year remission achieved in our patient.

We investigated the intensely positive emotional experiences arising from participation in a large-scale collective event. We predicted such experiences arise when those attending a collective event are (1) able to enact their valued collective identity and (2) experience close relations with other participants. In turn, we predicted both of these to be more likely when participants perceived crowd members to share a common collective identity. We investigated these predictions in a survey of pilgrims (N = 416) attending a month-long Hindu pilgrimage festival in north India. We found participants' perceptions of a shared identity amongst crowd members had an indirect effect on their positive experience at the event through (1) increasing participants' sense that they were able to enact their collective identity and (2) increasing the sense of intimacy with other crowd members. We discuss the implications of these data for how crowd emotion should be conceptualised.

Objectives In physiotherapeutic practice, special attention is being given to the reciprocal anatomical, physiological, and biomechanical relationship of the pelvis and the structures connected to it. However, the scientific literature shows mainly the theoretical information about their mutual connections. The lack of information about these relations from a practical aspect coupled with the paucity of scientific papers on the impact of posture changes on the pelvic floor led the authors to conduct this study. The primary aim of this study was to compare the resting and functional bioelectrical activities of pelvic floor muscles (PFMs) depending on three different positions of the lower limbs (positions A, B, and C) in the supine position. Materials and methods This was a prospective observational study evaluating resting and functional activities of the PFM depending on the position of the lower limbs. The study was carried out at the Department and Clinic of Urology, University Hospital in Wroclaw, Poland and the target group were women in the menopausal period. Bioelectrical activity of PFM was recorded using a surface electromyographic instrument in the supine position. Results of the values obtained in A, B, and C positions were compared using a one-way analysis of variance. Results In position A, the average resting surface electromyography (sEMG) activity of PFM was 6.9±2.6 µV; in position B, the result was 6.9±2.5 µV and in position C, the resting sEMG activity was 5.7±1.8 µV (P=0.0102). The results of the functional bioelectrical activity of PFM were as follows: position A – 20.3±11.8 µV, position B – 19.9±10.6 µV, and position C – 25.3±10.9 µV (P=0.0104). Conclusion The results showed that in the supine position, the PFM achieved the lowest resting activity and the highest functional activity. Therefore, the supine position can be recommended for the diagnosis and therapy of weakened PFM. PMID:28115836
Full Text Available Background The position of the mental foramen is critical for surgery and local anesthesia. Objectives This study was conducted to assess the position of the mental foramen and its relationship to age in a selected Iranian population. Materials and Methods This was a cross-sectional descriptive study. Three hundred panoramic radiographs were assessed. Three variables were assessed for each radiograph: anterior-posterior position, superior-inferior position, and radiographic appearance. The position and appearance of the mental foramen were recorded according to gender and age. The results were analyzed using Chi-square and Fisher’s exact tests. Results Considering the anterior-posterior position, the mental foramina were located in the following positions: between premolars (41.5%, at the apex of the second premolars (31.7%, in the posterior area of the second premolars (19.2%, in the anterior area of the first premolars (4.3%, and at the apex of the first premolars (3.3%.The superior-inferior position of the mental foramina were below, above, and at the level of the apices of the premolars in 78.8%, 2.5%, and 18.7% of cases, respectively. The appearance of the mental foramen was continuous in relation to the mandibular canal in 55.9% of cases, while it was separated, diffuse, and unidentified in 29.5%, 9.7%, and 5% of cases, respectively. Age was found to affect the position and appearance of mental foramen. Conclusions The mental foramina were most commonly located between the first and second premolars and below the apex. A continuous appearance was the most common appearance for the mental foramen, which was similar in males and females.

Full Text Available Self-report, i.e. explicit, measures of affect cannot fully explain the cardiovascular (CV responses to stressors. Measuring affect beyond self-report, i.e. using implicit measures, could add to our understanding of stress-related CV activity. The Implicit Positive and Negative Affect Test (IPANAT was administered in two studies to test its ecological validity and relation with CV responses and self-report measures of affect. In study 1 students (N = 34 viewed four film clips inducing anger, happiness, fear, or no emotion, and completed the IPANAT and the Positive And Negative Affect Scale at baseline and after each clip. Implicit negative affect (INA was higher and implicit positive affect (IPA was lower after the anger inducing clip and vice versa after the happiness inducing clip. In study 2 students performed a stressful math task with (n = 14 or without anger harassment (n = 15 and completed the IPANAT and a Visual Analogue Scale as an explicit measure afterwards. Systolic (SBP, diastolic (DBP blood pressure, heart rate (HR, heart rate variability (HRV and total peripheral resistance (TPR were recorded throughout. SBP and DBP were higher and TPR was lower in the harassment condition during the task with a prolonged effect on SBP and DBP during recovery. As expected, explicit negative affect (ENA was higher and explicit positive affect (EPA lower after harassment, but ENA and EPA were not related to CV activity. Although neither INA nor IPA differed between the tasks, during both tasks higher INA was related to higher SBP, lower HRV and lower TPR and to slower recovery of DBP after both tasks. Low IPA was related to slower recovery of SBP and DBP after the tasks. Implicit affect was not related to recovery of HR, HRV and TPR. In conclusion, the IPANAT seems to respond to film clip-induced negative and positive affect and was related to CV activity during and after stressful tasks. These findings support the theory that implicitly measured

Full Text Available Objective: Helicobacter pylori (HP is a bacterial pathogen that leads to gastroduodenal inflammation, gastric and duodenal ulcer and atrophic gastritis. Colonization of bacteria can be shown by using rapid-urease test during endoscopy. There are conflicting data about the route of transmission and reservoir. It’s thought to be transmitted primarily by oral route. Many studies showed results supporting that the presence of bacteria in dental plaques has effects on gastric colonization and eradication. There are data about the potential inhibitory effect of oral flora on HP. We aimed to analyze the association of simplified oral hygiene index -a possible representation of a healthy oral flora- with HP positivity. Methods: Patients undergoing upper gastrointestinal system endoscopy for symptoms of dyspepsia were assessed by a dentist for the simplified oral hygiene index (OHI. Patients were classified as good, poor and bad groups based on oral hygiene index scale. Pre-pyloric biopsy materials were assessed using rapid-urease test. Oral hygiene indexes were analyzed retrospectively, groups were compared for HP positivity. Results: 66 patients (30 females, 45.5% were included. Mean age of patients was 34.17±14.7 years. 11 (16.7%, 29 (43.9% and 26 (39.4% patients were classified as in good, poor and bad hygiene index groups, respectively. In patients with good OHI gastric HP positivity was less frequent. Conclusion: Decreased frequency in gastric HP may be observed with maintaining an ideal oral hygiene.

Full Text Available Abstract Introduction After removal of endotracheal tube and artificial ventilation, ventilatory support should be continued, offering oxygen supply to ensure an arterial oxygen saturation close to physiological. Objective: The aim of this study was to investigate the effects of positive-end expiratory pressure before extubation on the oxygenation indices of patients undergoing coronary artery bypass grafting. Methods: A randomized clinical trial with seventy-eight patients undergoing coronary artery bypass grafting divided into three groups and ventilated with different positive-end expiratory pressure levels prior to extubation: Group A, 5 cmH2O (n=32; Group B, 8 cmH2O (n=26; and Group C, 10 cmH2O (n=20. Oxygenation index data were obtained from arterial blood gas samples collected at 1, 3, and 6 h after extubation. Patients with chronic pulmonary disease and those who underwent off-pump, emergency, or combined surgeries were excluded. For statistical analysis, we used Shapiro-Wilk, G, Kruskal-Wallis, and analysis of variance tests and set the level of significance at P<0.05. Results Groups were homogenous with regard to demographic, clinical, and surgical variables. There were no statistically significant differences between groups in the first 6 h after extubation with regard to oxygenation indices and oxygen therapy utilization. Conclusion: In this sample of patients undergoing coronary artery bypass grafting, the use of different positive-end expiratory pressure levels before extubation did not affect gas exchange or oxygen therapy utilization in the first 6 h after endotracheal tube removal.

Skeletal muscles consist of slow-twitch and fast-twitch muscle fibers, which have distinct physiological and biochemical properties. The muscle fiber composition determines the contractile velocity and fatigability of a particular skeletal muscle. We analyzed the systemic distribution of slow muscle fibers in all rodent skeletal muscles by myosin ATPase staining and found that only seven hindlimb skeletal muscles were extremely rich in slow muscle fibers. These included the mouse piriformis (56.5%), gluteus minimus (35.7%), vastus intermedius (24.7%), quadratus femoris (69.9%), adductor brevis (44.3%), gracilis (24.6%), and soleus muscles (35.1%). In mice, the relative proportion of slow muscle fibers did not exceed 15% in skeletal muscles in other regions. The distribution of slow muscle fibers was well conserved in rats and rabbits. The soleus muscle is an important antigravity muscle in both rodents and humans; therefore, these skeletal muscles rich in slow muscle fibers might play an important role in sustaining neutral alignment of the lower extremity.
This essay addresses the problem of communication between Christianity and the secular world in an area where the latter tends to oppose the moral norms endorsed by the former. How, in the interest of missionary outreach (and with which understandings of what such outreach involves) can the language barriers be bridged? Whereas the Roman Catholic natural law tradition posits a neutral common ground of (traditional or hermeneutical) rationality between Christianity and the world, an Ebeling- and Barth-modified Lutheranism engages in an argument ad hominem by seizing upon an admitted deficiency within that world, and by recommending Christianity for mending that deficiency. Both positions differ from the Evangelical claim that since that which the world politically values is derived from Christianity, it must remain subject to Christianity's moral legislation. An entirely different approach to the communication- and outreach-problem is taken by Orthodox Christianity: The gulf which separates it from the world is acknowledged, and the possibility of trans-gulf-traffic is referred to God's grace. It is only this latter model, however, which preserves Christianity's theological terms (such as "Scripture", "law", and "holiness") from common-ground-securing, deficiency-mending, or authority-imposing secularizing, and thus from compromising that very theological context into which communicative outreach endeavors were to invite.

Water table position (WT) is an important factor in peatland ecosystem structure and function. The relationship between WT and net ecosystem production (NEP) is recognized, but poorly described, especially on a microscale level where factors such as vegetation and microhabitat may influence this relationship. Over two growing seasons, fluxes of CO2 and CH4, coupled with measurements of WT, were examined in a poor fen using static chambers. The goal of this research was to quantify the relationship between NEP and WT, peat surface microtopography (hummocks vs. lawns) and vegetation composition. The fen was a net sink of CO2 in both 2008 and 2009 of 0.94 and 1.04 mol m-2 yr-1 respectively. Averaged across two years, NEPSAT and dark respiration (measured NEP when PAR>1000 and when PAR= 0 μmol m-2 s-1, respectively) values were 3.52 ± 0.04 and -2.77 ± 0.03 μmol CO2 m-2 s-1 respectively. Significant interactions were seen between vegetation and year for both NEPSAT (F2,3034= 34.3, pevapotranpiration regimes anticipated with changing climate.Table1 Regression between water table position and NEP residuals (p<0.0001)
Full Text Available Aim: The aim of this study was to determine whether the characteristics of goal orientation and perceived motivational climate change according to the playing positions of amateur footballers. Material and Methods: Four hundred and sixty amateur male football players participated in the study (age, 21.72±4.63 years; football experience, 9.24±4.18 years. Footballers were named as the defence (n=199, midfield (n=187 and forward (n=74 according to their playing position. The scores of perceived motivational climate and goal orientation were determined by the Turkish versions of ‘The Task and Ego Orientation in Sport Questionnaire’ and ‘The Perceived Motivation Climate Questionnaire’, which were adopted by Toros (2002. Results: Pearson correlation analyses showed that football experience had no effect on task orientation, ego orientation, mastery climate, and performance climate. ANOVA and post-hoc Tukey tests showed that task orientation and mastery climate scores were higher in defence players than midfield players (p=0.003 vs. p<0.001. Ego orientation and performance climate scores of the midfield and defence players differed in favour of the midfield players (p<0.001 vs. p<0.001. Although there were no statistically significant differences in terms of the scores of task orientation and ego orientation among forward, defence, and midfield players, performance climate scores were higher in forward players than midfield players (p<0.001. Conclusion: According to the results of this study, players who have higher task orientation and mastery climate scores can play as defence players, and other players who have higher ego orientation and performance climate scores can play as midfield players. With the need for more extensive studies to determine the goal orientation and motivational climate scores of forward players, scores that are obtained from questionnaires should be evaluated with physical and physiological tests.

Cardiac arrest during spine surgery in the prone position is difficult to manage as poor access makes cardiopulmonary resuscitation and defibrillation difficult. Advanced age is the maximal risk factor for cardiac arrest. Therefore, we wanted to determine the relationship between age and cardiac risk factors/pre-operating tests for cervical spine surgery in the prone position. The inclusion criteria for this study specified 88 patients scheduled should undergo cervical spine surgery in the prone position. The patients were divided into two groups: Paients in group A (50 patients) were aged 69 and under, Group B (38 patients) 70 and above. All patients responded to a medical interview about eight cardiac risk factors including past history, chest symptoms, diabetes mellitus, hypertension, hyperlipidemia, obesity, smoking, and family history. All patients underwent physical examination and 24-h Holter ECG and echocardiography performed by two cardiologists before surgery. We analyzed relationships between cardiac risk factors and ECG/echocardiography and investigated intra- and postoperative cardiovascular complications. Although there were no significant differences in the number of cardiac risk factors between the two groups, the frequency of hypertension was significantly greater in Group B than in Group A. The frequency of abnormal ECG and echocardiography findings especially was significantly greater in Group B than in Group A. In ECG and echocardiography, three patients in Group B who had no cardiac risk factors before surgery showed abnormal findings, and one of the three patients had the amalgamation of arrhythmia after the operation. Also, in Group B, cardiovascular complications occurred in one case during operation. These results suggested that patients aged 70 and above should undergo ECG and echocardiography examination before cervical spine surgery in the prone position whether they have cardiac risk factors or not .

The study illustrates a research on the relationship between body image and lifestyles in a sample of 262 young amateur athletes that have a regular attendance of a gym in Cassino (Central Italy). The following questionnaires were used: Body Shape Questionnaire (BSQ34), International Physical Activity Questionnaire (IPAQ), Short form 12 items (SF12). The participants were 257 (response rate 98.1%) mainly of young age (18-24 years, 63.8%), single (72%), with a senior high school diploma (57.2%), students (63%). For almost all the BSQ-34 questionnaire items differences for gender were found, with Females more worried than males. 187 (72.8%) reported some vigorous activity during a week, 207 (80.5%) some moderate activity, and 229 (89.1%) walking. The participants had a median PCS score of 54.2 (range: 24.5-64.8) and a median MCS score of 43.8 (range: 9.3 - 58.7). The mean score of the Mediterranean diet was 4.8 (median = 5; Range = 1-8), and only 72 individuals (11.7%) had optimal score (over or equal to 6).

Abstract The concepts of genetic diversity and naturalness are well known as measures of conservation values and as descriptors of state or condition. A lack of research evaluating the relationship between genetic diversity and naturalness in biological communities, along with the possible implications in terms of evolutionary aspects and conservation management, make this subject particularly important as regards forest tree communities.We therefore examined the following hypothesis: the genetic diversity of a central-European tree stand averaged over species increases with the naturalness of the stand, as defined by the Potential Natural Vegetation (PNV). The results obtained show that the hypothesis is unsustainable because differences between the averaged genetic diversities of the unnatural and semi-natural stand classes (69 cases) were mostly non-significant. Moreover in three cases, the average genetic diversity of unnatural stand classes was significantly higher than the average genetic diversity of the semi-natural stand classes. A significantly lower average genetic diversity of unnatural stand class was not detected in the statistical analysis. Thus, the naturalness of a tree species community, as inferred from PNV, does not serve as a straightforward indicator of ecological stability when the genetic diversity and the adaptability of tree species are unknown.

We determined short- and long-term correlates of a revised introductory biology curriculum on understanding of biology as a process of inquiry and learning of content. In the original curriculum students completed two traditional lecture-based introductory courses. In the revised curriculum students completed two new learner-centered, inquiry-based courses. The new courses differed significantly from those of the original curriculum through emphases on critical thinking, collaborative work, and/or inquiry-based activities. Assessments were administered to compare student understanding of the process of biological science and content knowledge in the two curricula. More seniors who completed the revised curriculum had high-level profiles on the Views About Science Survey for Biology compared with seniors who completed the original curriculum. Also as seniors, students who completed the revised curriculum scored higher on the standardized Biology Field Test. Our results showed that an intense inquiry-based learner-centered learning experience early in the biology curriculum was associated with long-term improvements in learning. We propose that students learned to learn science in the new courses which, in turn, influenced their learning in subsequent courses. Studies that determine causal effects of learner-centered inquiry-based approaches, rather than correlative relationships, are needed to test our proposed explanation.

Alienation is a subjective state, a feeling of being a stranger, as if one were not one's normal self. It is also a sense of homelessness; a feeling of uneasiness or discomfort, which signifies the person's exclusion from social or cultural participation. Alienation can adversely affect healthy functioning of nursing students. Nursing students are the adolescents of today and the nurses of tomorrow who will deal with human behavior, and their psychological well-being will be important in managing their clients' conditions. Healthy nursing students are likely to become healthy nurses who can then model and promote healthy lifestyles for their patients. This study looked at whether the effects of alienation on adolescents' resourcefulness are influenced by positive cognitions. Zauszniewski's theory of resourcefulness, which is based on the conceptualization of two forms of resourcefulness: personal (self-help) and social (help-seeking) resourcefulness, served as the theoretical framework for the study. A descriptive, correlational, cross-sectional design was used to examine hypothesized relationships among the study variables in a convenience sample of 170 first-year nursing students aged 17 to 20 years. Results showed that positive cognitions had a moderating and a partial mediating effect on the relationship between alienation and resourcefulness. It is imperative for nurse educators to generate interventions to enhance positive cognitions among nursing students.

Emotional avoidance has been found to be associated with higher levels of anxiety. However, no research to date has differentiated between the avoidance of positive and negative emotions in relation to anxiety. Additionally, no studies have examined the extent to which attentional control moderates the relation between the avoidance of emotions and anxiety. Thus, the purpose of this study was to (a) clarify relations between both positive and negative emotional avoidance and anxiety, and (b) examine attentional control as a moderator of the relations between both positive and negative emotional avoidance and anxiety. A community sample of adults (N = 93) completed a series of questionnaires, as well as a laboratory-based measure of attentional control. Greater avoidance of both positive and negative emotions was associated with higher levels of anxiety. Additionally, attentional control moderated the relationship between negative (but not positive) emotional avoidance and anxiety. Specifically, the avoidance of negative emotions was associated with higher levels of anxiety for those with lower attentional control. Limitations include a cross-sectional design, use of self-report measures, and the examination of hypotheses within a non-clinical sample. Findings are consistent with a growing body of research demonstrating the moderating role of attentional control in the relation between risk factors and negative outcomes. Findings also suggest that empirically-based treatment approaches that contain attention-based components may be beneficial for emotionally avoidant individuals with poor attentional control abilities.

Ameloblastomas and keratocystic odontogenic tumors (KOTs) are lesions that are characterized by locally invasive growth and cause extensive bone destruction. In addition, it is known that E-cadherin influences the adhesion of Langerhans cells (LCs) to keratinocytes. The aim of this study was to investigate, using immunohistochemistry, the distribution of CD1a-positive cells in ameloblastomas and KOTs and their relationship with E-cadherin, in comparison to calcifying cystic odontogenic tumor (CCOT). The CD1a-positive LCs were observed in 11 ameloblastomas and KOTs. All of the cases of CCOT showed CD1a-positive LCs and a significant difference was found when this tumor was compared with ameloblastomas (P odontogenic tumors that were studied (P > 0.05, Spearman test). A quantitative difference of CD1a-positive cells between AMs and KOTs in comparison to CCOTs was observed. This permits to speculate that a depletion of CD1a-positive LCs might influence the local invasiveness of ameloblastomas and KOTs. Furthermore, it is suggested that E-cadherin mediates cell adhesion in these tumors. © 2012 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Meanwhile, the role of positive core beliefs about the self in cognitive vulnerability to depression is unknown. Therefore, we examined the relationship of negative and positive core beliefs about the self with dysfunctional attitudes in three aspects of life.Methods: The subjects were 311 Japanese volunteers. Core beliefs of negative-self and positive-self were evaluated by the corresponding subscales of the Brief Core Schema Scales. Dysfunctional attitudes in the areas of achievement, dependency and self-control were measured by the corresponding subscales of the 24-item Dysfunctional Attitude Scale.Results: The negative-self subscale was correlated with the achievement, dependency and self-control subscales. The positive-self subscale was correlated with the achievement and self-control subscales.Conclusion: The present study suggests that negative core beliefs about the self underlie all types of dysfunctional attitudes, while positive core beliefs about the self have some connections with dysfunctional attitudes related to achievement and self-control. Keywords: negative-self, achievement, dependency, self-control, depression

Fast ionization waves (FIWs), often generated with high voltage pulses over nanosecond timescales, are able to produce large volumes of ions and excited states at moderate pressures. The mechanisms of FIW propagation were experimentally and computationally investigated to provide insights into the manner in which these large volumes are excited. The two-dimensional structure of electron and metastable densities produced by short-pulse FIWs sustained in helium were measured using laser-induced fluorescence and laser collision-induced fluorescence diagnostics for times of 100–120 ns after the pulse, as the pressure was varied from 1 to 20 Torr. A trend of center-peaked to volume-filling to wall-peaked electron density profiles was observed as the pressure was increased. Instantaneous FIW velocities, obtained from plasma-induced emission, ranged from 0.1 to 3×10⁹cm s⁻¹, depending on distance from the high voltage electrode and pressure. Predictions from two-dimensional modeling of the propagation of a single FIW correlated well with the experimental trends in electron density profiles and wave velocity. Results from the model show that the maximum ionization rate occurs in the wavefront, and the discharge continues to propagate forward after the removal of high voltage from the powered electrode due to the potential energy stored in the space charge. As the pressure is varied, the radial distribution of the ionization rate is shaped by changes in the electron mean free path, and subsequent localized electric field enhancement at the walls or on the centerline of the discharge.

An imbalance of metal ions is implicated in the development of Alzheimer's disease (AD). We investigated the relationship between the annual mortality of AD and ionic concentration (iron, zinc, copper, and aluminum) in the soil in mainland China. The AD annual mortality data were from 26 provinces and 3 municipal districts within mainland China between the years 1991 and 2000 and provided by the National Death Cause Surveillance Database of China. The ionic concentration in soil was provided by the China State Environmental Protection Bureau, which was published in 1990. The results showed that the relative risk of mortality in the regions with the highest copper concentrations (60-80 mg/kg) reached 2.634 (95% CI: 2.626-2.642) compared with the regions that had the lowest copper concentrations. The relative risk was 1.292 (95% CI: 1.290-1.294) and 1.248 (95% CI: 1.245-1.251) when the soil iron concentrations exceeded 3 mg/kg and 4 mg/kg, respectively. When the soil zinc concentration was over 100 mg/kg and 200 mg/kg, the relative risk was 1.870 (95% CI: 1.859-1.881) and 2.289 (95% CI: 2.276-2.304), respectively. However, the relative risk was 0.560 (95% CI: 0.559-0.561), 0.604 (95% CI: 0.603-0.605), and 0.267 (95% CI: 0.265-0.268) when the soil aluminum concentration was over 6 mg/kg, 7 mg/kg, and 8 mg/kg, respectively. This study suggests that high concentrations of iron and copper in the soil might be associated with the high AD annual mortality in this region in China, while aluminum had no association with AD mortality.

With estimates of a 51% growth in the number of nursing assistants needed by 2016, there is a critical need to examine workplace factors that negatively contribute to the recruitment and retention of nursing assistants. Studies have shown that high demands, physical stress, and chronic workforce shortages contribute to a working environment that fosters one of the highest workforce injury rates in the United States. The aim of this study was to explore the relationship between nursing assistant injury rates and key outcomes, such as job satisfaction and turnover intent, while exploring workplace environment factors, such as injury prevention training, supervisor support, and employee engagement, that can decrease the rates of workplace injury. Data from the 2004 National Nursing Assistant Survey were used to examine the negative effects of workplace injury on nursing assistants and the workplace environment factors that are related to the rate of worker injury. Nursing assistants who experience job-related injuries have lower levels of job satisfaction, increased turnover intentions, and are less likely to recommend their facility as a place to work or seek care services. It was also found that nursing assistant injury rates are related to employee ratings of injury prevention training, supervisor support, and employee engagement. NAs with multiple injuries (>2) were 1.3-1.6 times more likely to report being injured at work than NAs who had not been injured when supervisor support, employee engagement, and training ratings were low. Evidence that health care organizations can use to better understand how workplace injuries occur and insight into ways to reduce the current staggering rate of on-the-job injuries occurring in health care workplaces were offered in this study. The findings also offer empirical support for an extension of the National Institute for Occupational Health and Safety/National Occupational Research Agenda Work Organization Framework for

Eukaryotic development and stem cell control depend on the integration of cell positional sensing with cell cycle control and cell wall positioning, yet few factors that directly link these events are known. The DEFECTIVE KERNEL1 (DEK1) gene encoding the unique plant calpain protein is fundamental for development and growth, being essential to confer and maintain epidermal cell identity that allows development beyond the globular embryo stage. We show that DEK1 expression is highest in the actively dividing cells of seeds, meristems and vasculature. We further show that eliminating Arabidopsis DEK1 function leads to changes in developmental cues from the first zygotic division onward, altered microtubule patterns and misshapen cells, resulting in early embryo abortion. Expression of the embryonic marker genes WOX2, ATML1, PIN4, WUS and STM, related to axis organization, cell identity and meristem functions, is also altered in dek1 embryos. By monitoring cell layer-specific DEK1 down-regulation, we show that L1- and 35S-induced down-regulation mainly affects stem cell functions, causing severe shoot apical meristem phenotypes. These results are consistent with a requirement for DEK1 to direct layer-specific cellular activities and set downstream developmental cues. Our data suggest that DEK1 may anchor cell wall positions and control cell division and differentiation, thereby balancing the plant's requirement to maintain totipotent stem cell reservoirs while simultaneously directing growth and organ formation. A role for DEK1 in regulating microtubule-orchestrated cell wall orientation during cell division can explain its effects on embryonic development, and suggests a more general function for calpains in microtubule organization in eukaryotic cells. © The Author 2015.

Full Text Available Because the frequency of heterospecific interactions inevitably increases with species richness in a community, biodiversity effects must be expressed by such interactions. However, little is understood how heterospecific interactions affect ecosystem productivity because rarely are biodiversity ecosystem functioning experiments spatially explicitly manipulated. To test the effect of heterospecific interactions on productivity, direct evidence of heterospecific neighborhood interaction is needed. In this study we conducted experiments with a detailed spatial design to investigate whether and how heterospecific neighborhood interactions promote primary productivity in a grassland community. The results showed that increasing the heterospecific: conspecific contact ratio significantly increased productivity. We found there was a significant difference in the variation in plant height between monoculture and mixture communities, suggesting that height-asymmetric competition for light plays a central role in promoting productivity. Heterospecific interactions make tall plants grow taller and short plants become smaller in mixtures compared to monocultures, thereby increasing the efficiency of light interception and utilization. Overyielding in the mixture communities arises from the fact that the loss in the growth of short plants is compensated by the increased growth of tall plants. The positive correlation between species richness and primary production was strengthened by increasing the frequency of heterospecific interactions. We conclude that species richness significantly promotes primary ecosystem production through heterospecific neighborhood interactions.

Full Text Available Constructed as new and located in the discourse of positive psychology, “spiritual well-being” is a signifier with a (hisstory in which one possible reading is highlighted in this postmodern (deconstructive narrative. The construction of “spiritual + well-being” could be narrated as a secularisation of the religious by positivist psy-complex knowledges, where spiritual well-being is reconstructed as a measurable outcome. Or it could be nar-rated as a “spiritualisation” of the psy-complex by religious knowledges, with measurable well-being becoming dependent on the pursuit of the postmodern, multiple-storied spiritual/ religious features. As the psy-complex has followed medicine from a focus on pathology to a focus on holistic wellness, it has found itself in the religious realm which it has simultaneously centred and marginalised. Additionally, as the psy-complex has moved from measuring illness to measuring wellness, it could be described as having constructed new categories of non-well-being or ill-being.

Full Text Available The cardiovascular complications that frequently accompany obstructive sleep apnea syndrome (OSAS are thought to develop as a result of inflammatory stress associated with cytokines such as IL-6 and TNF-α. We conducted the current study to compare levels of these cytokines in OSAS patients (n=33 and nonapneic controls (n=24. Furthermore, we investigated the impact of a three-month regime of continuous positive airway pressure (CPAP on serum levels of IL-6 and TNF-α only in the OSAS patients. There were no significant differences in serum levels of either IL-6 (P=0.782 or TNF- α (P=0.722 or TNF-α (P=0.722 between OSAS patients and nonapneic controls. Serum IL-6 levels correlated significantly with neck circumference in OSAS patients (P=0.006. In OSAS patients, reduced levels of TNF-α and IL-6 correlated with increases in mean SaO2 after CPAP treatment (P=0.020 and P=0.051, resp.. However, neither of cytokine levels was significantly impacted by CPAP therapy (both P>0.137. We have demonstrated that plasma cytokine levels are similar in both otherwise healthy subjects with OSAS and in nonapneic control, and we conclude that OSAS-related parameters and CPAP treatment do not play a significant role in altering cytokine levels.

Recent simulations by So et al (2002 J. Phys. D 35 2978-87) have shown inter alia that in CF sub 4 where there are two negative ions of comparable density, the plasma is structured, in that there are essentially three regions so far as the negative ions are concerned. In the inner region one negative ion species is concentrated, in the outer region electrons dominate over negative ions, while the intermediate has only one species of negative ion. This confirms earlier work (Franklin R N 2002a J. Phys. D: Appl. Phys. 35 536-42; 2002b J. Phys. D: Appl. Phys. 35 747-50) and justifies extending that work to cover situations where there is a multiplicity of both positive and negative ions. In this paper we give explicit results for the central electronegativities and electropositivities for the case of two species of ion of each sign, and also determine the relative sizes of the regions occupied by the negative ions. By effectively varying the electron temperature through the ionization rate, we indicate how these...
Full Text Available This technical report describes an interactive game environment designed to bring mothers and their adolescent daughters together to discuss three issues that have previously been shown in the literature to be of concern to families, as young girls transition from middle childhood to the adolescent years. The game is called Knowing you, Knowing me or KYKM, and is used to help mothers and daughters discuss the following three topics: positive communication skills, relationship building, and managing risky behaviours in the social environment. As the game remains untested, its limitations and future implications of its utility are discussed.

Full Text Available INTRODUCTION: Recent research suggests that diet quality influences depression risk; however, a lack of experimental evidence leaves open the possibility that residual confounding explains the observed relationships. The aim of this study was to document the cross-sectional and longitudinal associations between dietary patterns and symptoms of depression and to undertake a detailed examination of potential explanatory factors, particularly socioeconomic circumstances, in the diet-depression relationship. METHODS: Data were drawn from the Personality and Total Health (PATH Through Life Study, a longitudinal community study following three age cohorts (20+; 40+; 60+yrs from south-eastern Australia over three assessment periods (n=3663. Regression analyses evaluated the cross-sectional and longitudinal relationships between dietary patterns, depressive symptoms, age, detailed measures of socioeconomic circumstances, other health behaviours, and cardiovascular risk factors. RESULTS: The lowest tertile of prudent (healthy dietary pattern and the highest tertile of western (unhealthy dietary pattern were associated with an increased likelihood of depressive symptoms. However, these contemporaneous associations were explained by adjustment for detailed measures of socioeconomic circumstances and physical activity. In prospective analyses, lower scores on the healthy dietary pattern and higher scores on the unhealthy dietary pattern independently predicted increased depressive symptoms across time, before and after adjustment for potential confounders and baseline depressive symptoms, but only for those in the oldest cohort. Dietary patterns did not explain the relationship between socioeconomic position and depressive symptoms. CONCLUSION: The results of this study confirm that the relationship between habitual dietary intake and depressive symptoms is somewhat explained by socioeconomic circumstances and other health behaviours, but suggest that long

The association of trauma exposure and coping style to sexual risk behavior has yet to be fully examined in the context of primary and casual sexual partnerships. The current study assessed a high risk sexual behavior-unprotected anal intercourse (UAI)-in a high risk population of HIV-positive men who have sex with men (MSM) with a history of trauma. Using audio computer-assisted self-interview technology, 132 HIV-positive MSM completed measures of trauma exposure, trauma symptoms, coping strategies, and sexual risk behavior. Hierarchical logistic regression analyses indicated that completing more years of education and having experienced sexual abuse were positively associated with UAI with casual partners. Additionally, use of active coping was negatively associated with UAI with casual partners and the final model significantly predicted variance in UAI with casual partners. However, no variables were significantly associated with UAI with primary partners, suggesting that sexual risk behavior with primary partners may be associated with factors not commonly assessed in risk prediction or prevention research. We discuss the results in the context of developing new or modifying existing interventions to address rates of sexual risk in the relationships of HIV-positive MSM.

The long-term bed-rest was organized by ESA and CNES, in order to simulate the physiological effects of weightlessness: eight volunteers had to stay 42 days in bed, in a head down tilt position (-6 °). There were two subjects in a room, they could not be alone and it was difficult for them to have their own personal space and intimacy. In these circumstances, as in outer space, interpersonal relationships were of prime importance. This situation enabled us, through systematic observation, to analyze the evolution of the relational behavior in dyads, and to quote some social indicators of adaptation. Results show significant withdrawal, and the time spent alone was marked by the emergence, during the experiment, of specific preferential activities. Behavioral contagion was observed in each dyad (people engaged in the same activities at the same time), except in the one case of abandon. Moreover, the highest rates of inactivity and withdrawal were noted in this case. Verbal indicators were useful to comment these results and showed that, for all the dyads, one of the two subjects always played a regulating role by expressing a very positive perception of the situation. These results emphasize the importance of psycho-sociological factors in isolation and confinement. Thus, it appears that different modalities of interpersonal relationships, and not only verbal interactions, play a significant role in adaptation to stress situations.

While culture's effect on the coping process has long been acknowledged in the stress-coping literature conceptually, empirical evidence and attempts to discern the specific relationship between culture and coping remain very scarce. Against this backdrop, the present study applied the Cultural Transactional Theory (Chun, Moos, & Cronkite, 2006) to examine the mediating role of cultural coping behaviours (Collective, Engagement and Avoidance Coping) on the relationship between academic stress (AS) and two positive psychosocial well-being outcome measures: Collective Self-esteem (CSE) and Subjective Well-being (SWB). Responses from a sample of undergraduate students in Canada (N = 328) were analysed to test a theory-driven, hypothesised model of coping using structural equation modelling (SEM). As hypothesised, the SEM results showed that: (a) the proposed cultural coping model fit the data well; (b) Engagement Coping and Collective Coping partially mediated the association between AS and the outcomes and (c) the path relationships among the constructs were in the hypothesised directions. A set of preliminary exploratory analyses indicated that Collective Coping was most strongly endorsed by the African/Black and the Middle Eastern cultural groups as compared to other ethnic groups. Implications of the study's findings for future research and practice concerning culture, stress, and coping are discussed. © 2017 International Union of Psychological Science.
The Long-Term Benefits of Positive Self-Presentation via Profile Pictures, Number of Friends and the Initiation of Relationships on Facebook for Adolescents' Self-Esteem and the Initiation of Offline Relationships.
Metzler, Anna; Scheithauer, Herbert
Social networking sites are a substantial part of adolescents' daily lives. By using a longitudinal approach the current study examined the impact of (a) positive self-presentation, (b) number of friends, and (c) the initiation of online relationships on Facebook on adolescents' self-esteem and their initiation of offline relationships, as well as the mediating role of positive feedback. Questionnaire data were obtained from 217 adolescents (68% girls, mean age 16.7 years) in two waves. Adolescents' positive self-presentation and number of friends were found to be related to a higher frequency of receiving positive feedback, which in turn was negatively associated with self-esteem.

Social networking sites are a substantial part of adolescents’ daily lives. By using a longitudinal approach the current study examined the impact of (a) positive self-presentation, (b) number of friends, and (c) the initiation of online relationships on Facebook on adolescents’ self-esteem and their initiation of offline relationships, as well as the mediating role of positive feedback. Questionnaire data were obtained from 217 adolescents (68% girls, mean age 16.7 years) in two waves. Adolescents’ positive self-presentation and number of friends were found to be related to a higher frequency of receiving positive feedback, which in turn was negatively associated with self-esteem. However, the number of Facebook friends had a positive impact on self-esteem, and the initiation of online relationships positively influenced the initiation of offline relationships over time, demonstrating that Facebook may be a training ground for increasing adolescents’ social skills. Implications and suggestions for future research are provided. PMID:29187827

Cellular senescence is a cell fate program that entails essentially irreversible proliferative arrest in response to damage signals. Tumor necrosis factor-alpha (TNFα), an important pro-inflammatory cytokine secreted by some types of senescent cells, can induce senescence in mouse and human cells. However, downstream signaling pathways linking TNFα-related inflammation to senescence are not fully characterized. Using human umbilical vein endothelial cells (HUVECs) as a model, we show that TNFα induces permanent growth arrest and increases p21CIP1, p16INK4A, and SA-β-gal, accompanied by persistent DNA damage and ROS production. By gene expression profiling, we identified the crucial involvement of inflammatory and JAK/STAT pathways in TNFα-mediated senescence. We found that TNFα activates a STAT-dependent autocrine loop that sustains cytokine secretion and an interferon signature to lock cells into senescence. Furthermore, we show STAT1/3 activation is necessary for cytokine and ROS production during TNFα-induced senescence. However, inhibition of STAT1/3 did not rescue cells from proliferative arrest, but rather suppressed cell cycle regulatory genes and altered TNFα-induced senescence. Our findings suggest a positive feedback mechanism via the STAT pathway that sustains cytokine production and reveal a reciprocal regulatory role of JAK/STAT in TNFα-mediated senescence.

Urine culture is the most frequently requested test for a Microbiology Lab. A reliable screening tool would be of paramount importance both to clinicians and laboratorians, provided that it could get fast and accurate negative results in order to rule-out urinary tract infection (UTI). We evaluated 1907 consecutive urine samples from outpatients. Culture was performed on chromogenic agar with 1μL loop, using 10(5)CFU/mL as a limit of positive growth. Using Sysmex Uf-1000i analyzer we evaluated bacteria forward scatter (B_FSC) and fluorescent light scatter (B_FLH) in a preliminary discrimination step for UTI caused by Gram+ or Gram- bacteria. We got 512 positive samples. A mono-microbial infection was observed in 490 samples; two bacterial strains were isolated in 22 samples, so 534 bacterial strains were found: 392 Gram-, 133 Gram+ and 9 yeasts. Comparing Gram+ and Gram- bacteria we observed a statistically significant difference for B_FSC but not for B_FLH. In this application experimental cut-off value for B_FSC was 25ch. Using this cut-off to perform a presumptive identification of UTI sustained by Gram-+ bacteria, we observed a SE 0.68, SP 0.84. Our data although preliminary suggest that B_FSC could be useful in presumptive exclusion of UTI caused by Gram-positive bacteria. Copyright © 2014 Elsevier B.V. All rights reserved.

Rate of delivery of psychostimulants has been associated with their positive euphoric effects and potential addiction liability. However, information on individual differences in onset of d-amphetamine's effects remains scarce. We examined individual differences in the time to peak subjective and physiological effects and the pharmacokinetics/pharmacodynamics of oral d-amphetamine. We considered two independent studies that used different dosing regimens where subjects completed the drug effects questionnaire at multiple time points post d-amphetamine. Based on the observation of distinct individual differences in time course of drug effects questionnaire "feel", "high", and "like" ratings (DEQH+L+F) in Study 1, subjects in both studies were categorized as early peak responders (peak within 60 minutes), late peak responders (peak > 60 minutes) or nonresponders; 20-25% of participants were categorized as early peak responders, 50-55% as late peak responders and 20-30% as nonresponders. Physiological (both studies) and plasma d-amphetamine (Study 1) were compared among these groups. Early peak responders exhibited an earlier rise in plasma d-amphetamine levels and more sustained elevation in heart rate compared to late peak responders. The present data illustrate the presence of significant individual differences in the temporal pattern of responses to oral d-amphetamine, which may contribute to heightened abuse potential. © The Author(s) 2016.

Repeated-sprint ability (RSA) in essential for soccer. Important considerations when assessing RSA is whether there are differences between positions (defenders, midfielders, forwards), and what physiological characteristics may contribute to RSA. This has not been assessed in collegiate male players. Eighteen Division I male field players from one school performed several performance tests. The RSA test involved 7 x 30-m sprints completed on 20-s cycles. Measurements included total time (TT), and performance decrement (percent change in time from the first to last sprint; PD). Subjects also completed tests of lower-body power (vertical [VJ] and standing broad [SBJ] jump); linear (30-m sprint; 0-5, 0-10, 0-30 m intervals) and change-of-direction (505) speed; and soccer-specific endurance (Yo-Yo Intermittent Recovery Test Level 2; YYIRT2). A one-way ANOVA (p RSA TT and PD with the other tests. There were no significant between-position differences for any test. There were large effects for the faster right-leg 505 and greater YYIRT2 distance for midfielders compared to defenders and forwards. Nonetheless, no between-position differences in RSA TT and PD were documented. There were relationships between RSA TT and the VJ (r = -0.59), SBJ (r = -0.61), 0-10 m (r = 0.64) and 0-30 m (r = 0.83) sprint intervals. There were no significant correlations for RSA PD. Male field players from one collegiate soccer team can demonstrate similar RSA across different positions. Greater lower-body power and sprinting speed could augment RSA.
Full Text Available Petr Schalek, Zuzana Hornáčková, Aleš Hahn Ear, Nose and Throat department, 3rd Medical Faculty of Charles University, Prague, Czech Republic Background: Acute rhinosinusitis (ARS has been shown to significantly reduce patient quality of life (QoL. While the QoL in patients with chronic rhinosinusitis has been the subject of intensive research over the last decade, studies measuring the impact of ARS on patient QoL have remained relatively scarce. The aim of this study was to determine the relationship between the QoL and parameters suggestive of acute bacterial rhinosinusitis (C-reactive protein [CRP] levels and positive culture and to see if measurement of the QoL could be used as an indicator for antibiotic treatment in ARS.Methods: Eighty patients with ARS were enrolled in the study. A novel QoL instrument for patients with ARS, called Measurement of Acute Rhinosinusitis (MARS questionnaire, was given to patients at the time of diagnosis. We assessed patient QoL, obtained endoscopically guided cultures from the middle meatus, and measured levels of CRP. The relationship between QoL MARS scores (QoL-Mscores and CRP was determined using a correlation coefficient. To compare QoL-Mscores, relative to culture-positive and culture-negative patients, the Student’s t-test was used.Results: No correlation between the QoL, assessed using the MARS questionnaire, and positive middle meatus culture was demonstrated (P=0.332. A weak correlation was found between QoL-Mscores and CRP values, with a correlation coefficient of 0.221 and P=0.0498.Conclusion: No correlation between the QoL in ARS patients and positive culture was found in this study. The clinical significance of the correlation between QoL-Mscores and CRP values in the antibiotic decision making process needs further research.

This article explores the complex, dynamic and contextual frameworks within which men working in a mining community and their live-in long-term partners or spouses (termed "couples" in this study) respond to the introduction of HIV into their heterosexual relationships; the way in which partners adopt gendered positions in enabling them to make sense of their illness; how they negotiate their respective masculine and feminine roles in response to the need for HIV-related lifestyle changes; as well as the gendered nature of partner support in relation to antiretroviral therapy (ARV) adherence. We conducted an in-depth qualitative study with a sample of 12 HIV-positive seroconcordant heterosexual couples in a South African mining organization. Transcripts based on semi-structured couple's interviews were analyzed using an inductive emergent thematic analytical method. The findings present compelling evidence that the impact of HIV and AIDS is mitigated, in the main, by the nature of the dyadic relationship. Where power and agency were skewed in accordance with traditional gender scripts, the impact of HIV and AIDS was deleterious in terms of negotiating disclosure, meeting expectations of care and support, and promoting treatment adherence. As a corollary, the study also revealed that where the relational dynamic evidenced a more equitable distribution of power, the challenge of negotiating illness was embraced in a way that strengthened the couples' affiliation in profound ways, manifested not simply in a reduction in risk behaviours, but in both partner's courage to re-visit sensitive issues related to managing their relationship in the context of a debilitating illness. Gendered positioning (by self and others) was found to play a crucial role in the way couples experienced HIV and ARV treatment, and underscored the positive role of a couples-counselling approach in the negotiation of the illness experience.

The publication of the Brundtland Report in 1987 put the topic of sustainable development on the political and corporate agenda. Defining sustainable development as “a development that meets the needs of the future without compromising the ability of future generations to meet their own needs......” (WCED, 1987, p. 43), the Report also put a positive spin on the issue of sustainability by upholding capitalist beliefs in the possibility of infinite growth in a world of finite resources. While growth has delivered benefits, however, it has done so unequally and unsustainably. This thesis focuses...... on the textile and fashion industry, one of the world’s most polluting industries and an industry to some degree notorious for leading the ‘race to the bottom’ in global labour standards. Despite being faced with increasing demands to practise sustainability, most textile and fashion companies continue to fail...

Full Text Available Recent policy changes in sustainability reporting, such as the ones related to the new European Directive on non-financial disclosure (2014/95/EU, the standards issued by the American Sustainability Accounting Standard Board (SASB, the G4 guidelines issued by the Global Sustainability Standard Board (GSSB, and the framework of the International Integrated Reporting Council (IIRC stress the importance of extending the disclosure of ethical, social, and environmental risks within financial and social-environmental reporting. Institutional pressure has notably increased among organizations, in setting up risk management tools to understand sustainability risks within managerial and reporting practices. Given such institutional pressure, the corporate reaction in providing additional sustainability risk disclosure calls for attention and scrutiny. Therefore, this study aims at addressing such issues from an exploratory perspective. We based our analysis on a sample of large Italian organizations that issued sustainability disclosure in accordance with the Global Reporting Initiative (GRI, G4 guidelines, and we tested the relationship between their level of risk disclosure and other relevant variables. Consistently with the literature, we found that “experienced” sustainable reporters provide a significant volume of disclosure, and that disclosure quality on risk is positively influenced by their international presence and reporting experience. However, when accounting for specific risk-related areas of disclosure, only a few of them seem to adopt a managerial perspective linking strategy, risk metrics, and disclosure.

Mental health education is a central part of school nurses' practice. Mental health literacy is an asset for health that educational initiatives can strengthen, and a significant determinant of mental health. This study was intended to examine the relationship between positive mental health literacy (PMeHL) and mental well-being to discuss its implications for school health services' mental health education. The relationship was assessed using a multiple linear regression model controlling for relevant covariates. Data were derived from a cross-sectional school-based survey including 1,888 adolescents aged 15-21 years (response rate 97.3%). A weak gender difference was found in PMeHL. The regression model accounted for 41% of the variance in adolescents' mental well-being; PMeHL was a significant explanatory variable of mental well-being. Accordingly, the current study found support for including PMeHL, or knowledge of how to obtain and maintain good mental health, as an integral component of school health services' mental health education among adolescents.

Objective Examine factors that mediate parent-infant relationships 12 months after positive newborn screening (NBS). Method We examined effects of infant diagnosis, parents’ perceptions of child vulnerability and child attachment, parental depression and anxiety on parent-infant feeding interactions for 131 mothers and 118 fathers of 131 infants whose NBS and diagnostics confirmed cystic fibrosis (CF, n=23), congenital hypothyroidism (CH, n=35), CF carrier status (CF-C, n=38), or healthy, normal NBS (H, n=35). Results Separate composite indicator structural equation models for mothers and fathers showed neonatal diagnosis was not associated with increased anxiety or depression. In comparison to the H group, CF group parents reported higher perceptions of child vulnerability (paffective involvement and verbalization was associated with high infant affective expressiveness, communicative skills, and social responsiveness (mothers’ paffect and/or inconsistent and intrusive behavior was associated with infant dysregulation and irritability (mothers’ paffect parents’ perceptions of their child’s vulnerability and attachment. Infant feeding problems in the context of chronic health conditions, like CF, could represent signs of more deeply rooted concerns regarding the parent-child relationship that merit additional clinical evaluation.

Full Text Available DOI: http://dx.doi.org/10.5007/2175-8077.2012v14n32p141 This paper aims to investigate the relationship between social and environmental investments and the inclusion of companies in the Corporate Sustainability Index of BM&FBOVESPA, by applying logistic regression. For this, we analyzed information relating to internal and external social and environmental investments, from the social balance of companies.The sample consisted of companies eligible for inclusion in the portfolio ISE in the period of December 2009 to December 2010. According to the results, we can conclude that there is a relationship between environmental investments and entry of firms in the portfolio ISE of BM&FBOVESPA, showing that investment made and evidenced in social and environmental issues is a sign of real commitment to social responsibility and sustainability and not simply a form of accountability of the funds invested. As the variables used, internal social investment (II, External (IE and environmental (IA, we found that IE is the best proxy to explain this relationship. In other words, the results suggest that companies that invest resources in favor of community, either voluntarily or through taxes, which is or should be a resource applied in society, has more chances of entering the ISE portfolio composition.

Full Text Available Abstract Background The aim of this study was to determine the rate of sustained virological response (SVR and various factors associated with response rates in chronic hepatitis C infected patients treated with interferon alpha and ribavirin combination therapy. Methods A retrospective review of patients data collected at this Centre from 2001 to 2007 was performed. Out of 731 consecutive patients 400 patients that fulfilled the study criteria were evaluated and subsequently treated with a combination of interferon alpha 2b (3 MU subcutaneously three injections weekly and ribavirin (800–1200 mg orally daily. Treatment were administered for either 24 weeks or 48 weeks and patients were followed for an additional 6 months thereafter. End of the treatment response (ETR, SVR and side effects were recorded. Results Out of 400 patients, 394 completed the entire treatment course and six patients discontinued treatment at month 2. Over 67% responded at the end of treatment and 16% suffered relapse. Among all treated patients, 47.6% males and 56.7% females had sustained viral response with a total combined sustained viral response rate of 50.5%. Rapid response was seen in 46.5% patients. In a multivariate logistic regression analysis, slow virological responders (adjusted OR 2.6 [95% CI 1.9–3.7], HCV genotype 1&4 (adjusted OR 2.4 [95% CI 1.7–3.5], pre-treatment viral load > 0.2 MIU/mL (adjusted OR 2.2 [95% CI 1.8–4.2], Panjabi ethnic group (adjusted OR 1.6 [95% CI 1.0–3.2] and Age > 40 years (adjusted OR 1.5 [95% CI 0.9–2.4] were independent risk factors for non response. Side effects were usual and tolerable and only 1.5% discontinued the treatment. Conclusion The best positive predictor for SVR in this country are: rapid virologic response, HCV genotype 2 & 3, age

The objective of this study was to evaluate the relationship between intra-articular adhesions (IA) and disc position on magnetic resonance imaging (MRI) and direct arthroscopic vision, and to compare the presence of IA and clinical symptoms in patients diagnosed with internal derangements (ID) of temporomandibular joint (TMJ), along with their clinical outcomes. A total of 67 patients (134 TMJs) were included in the study. All patients were refractory to previous conservative treatment, and MRI was performed before surgery in all cases. The incidence of IA was evaluated in relation to disc displacement, type of displacement (with or without reduction), and stage of ID according to the Wilkes-Bronstein classification. Patients were divided into an adhesion and non-adhesion group. The association between the two groups with respect to preoperative clinical parameters (maximal interincisal opening, locking duration, joint pain, patient age) and postoperative parameters at 6 and 12 months was evaluated. The incidence of IA was 44% and the most common location was the anterior recess of the joint. IA were found in 58.3% of the joints with disc displacement without reduction, and in 28.9% of those with disc displacement with reduction (p joints with well-positioned discs, adhesions were found in 15% of the cases. Patient age and locking duration were significantly higher in the adhesions group (p joints with well-positioned discs or displacement with reduction, which leads to the hypothesis that disc hypomobility is an important factor in the genesis of adhesions.

This article describes the Sustainable Cities Program in Ibadan City, Nigeria. The program began in 1994, with an Environmental Planning and Management approach as part of the Sustainable Ibadan Project (SIP). The aim was to involve stakeholders in assessment and priority setting on urban environmental issues. Stakeholders include government officials, community leaders, people and organizations in the private sector, and international agencies. Stakeholders were sensitized and mobilized about the SIP through formal/informal meetings and well-organized sectoral briefings on trade, health, business, education, transportation, and traditional rulers. Stakeholders were asked to identify, articulate, clarify, and prioritize environmental issues in Ibadan. This approach led to changes in the way sectors identified issues and problems. A 1995 City Consultation among stakeholders led to a Declaration that identified and prioritized environmental issues. Multisectoral and interorganizational working groups were set up to address issues of waste recycling, water supply, and environmental sanitation in Bodija Market, and the Odo-Akeu Spring Water Development Project. The spring water project led to the development of a plan to enhance supply of hygienic water in a densely developed, unplanned area of the city. Project outcomes included the mobilization of human and financial resources that previously were unavailable. The project was successful in mobilizing apathetic communities to work with local governments to jointly develop action plans, ensuring healthy sustainable development.

Full Text Available As sustainability reporting has emerged as one of the most critical issues in the business world, this research aims to investigate the relationship between sustainability reporting and firm value based on listed companies in Singapore. We use an established sustainability reporting assessment framework and test how both the adoption and quality of sustainability reporting are related to a firm’s market value. Empirical results suggest that sustainability reporting is positively related to firm’s market value and this relationship is independent of sector or firm status such as government-linked companies and family businesses.
Full Text Available This paper discusses possible contributions of psychologists to sustainable transportation. It is argued that in order to reach sustainable transportation, among others, behaviour changes of individual car users are needed. As transport policies will be more effective if they target important antecedents of travel behaviour, first, factors influencing such behaviour are discussed. It is argued that car use is very attractive and sometimes even necessary for many different reasons. This implies that a combination of policies is called for, each targeting different factors that support car use and hinder the use of more sustainable modes of transport. Next, the paper elaborates on policy strategies that may be employed to achieve sustainable transportation by changing car use. Increasing the attractiveness of sustainable transport modes by means of pull measures seems not sufficient to reduce the level of car use. Besides, car use should be made less attractive by means of push measures to force drivers to reconsider their travel behaviour. The acceptability of such policies may be increased by clearly communicating the aim of these policies, and the expected positive consequences (e.g., less congestion, improved environmental quality. Moreover, possible negative effects for individual freedom may be compensated by implementing additional policies aimed at facilitating the use of sustainable transport modes.

Coagulase-positive staphylococci (CoPS) are opportunistic pathogens carrying various mechanisms of resistance that have a large number of virulence factors, and whose ability to induce illness is associated with the host. This study aimed to investigate the presence of environmental coagulase-positive staphylococci, their susceptibility profile, clonal relationship and ability to form biofilm. The 16S rRNA genes from CoPS isolates were analyzed, and their antibiotic susceptibility was evaluated using the agar dilution method in accordance with Clinical and Laboratory Standards Institute guidelines. The clonal profile was obtained by pulsed-field gel electrophoresis (PFGE) and biofilm formation was measured by a crystal violet retention assay. A total of 72 Staphylococcus spp. strains were isolated from air, metal surfaces, and nostrils from humans, dogs, cats, and birds. Three species were identified: Staphylococcus aureus (17%), Staphylococcus intermedius (63%), and Staphylococcus pseudintermedius (21%). Ninety three percent (93%) of the strains were resistant to at least one of 13 tested antibiotics. S. pseudintermedius strains were the only resistant ones to methicillin while most of these isolates were multidrug-resistant, had significantly higher ability to form biofilm and PFGE grouped into seven different patterns, without showing clonal dispersion among animals and environmental isolates. This study suggests that dogs, cat, and air are environmental sources potentially carrying multidrug-resistant S. pseudintermedius, which survives in different environments through biofilm formation and multidrug resistance, characteristics that can be transmitted horizontally to other bacteria and exacerbate the problem of antibiotic resistance in humans.

The anatomy of the proximal phalanges of the human hand has been widely described. Nevertheless, when consulting osteology and anatomy publications, the general opinion of researchers is that siding and allocating the proximal phalanges with regard to finger position is difficult, if not impossible. We provide morphological criteria for determining the side of the proximal phalanges and a metric means of allocating a phalanx to a specific finger. This paper also quantifies the absolute and directional asymmetry found in phalanges within this sample. The sample studied consists of three groups, one modern and two archaeological. To investigate these, three measurements were taken-maximum length, maximum width at the base and maximum width at the head. It was found that phalanges could be assigned correctly to the side and finger of origin in 100% of the cases when the five phalanges of a given hand were present, and that this result dropped to 92% when allocating isolated phalanges. The means of the measurements taken were larger in the modern group and a constant relationship between the greater basal width of the second and the fourth proximal phalanges was found. 2010 Elsevier GmbH.

The incidence of heterosexual HIV transmission continues to increase in the US. However, little is known about factors that influence high-risk behavior among men who do not have sex with men (MDSM). This study examines the association of childhood sexual abuse and high-risk behaviors among MDSM. The Coping with HIV/AIDS in the Southeast (CHASE) study included 611 HIV-positive individuals in the Southeastern U.S. Bivariate statistics were used to examine the influence of childhood sexual abuse among MDSM, MSM, and women. Study findings indicated that among MDSM with HIV, childhood sexual abuse predicted a higher number of sexual partners, alcohol and drug use problems, depression, PTSD, and less trust in medical providers. Similar statistically significant relationships between childhood sexual abuse and negative outcomes were not found for MSM and women with the exception of childhood sexual abuse predicting PTSD and alcohol use in women. Study findings indicate a need for more in-depth research to examine the role of childhood sexual abuse in shaping adult risk behaviors among MDSM as well as a need to assess for and address childhood sexual abuse in this population.

Low back pain is reported by more than half of cyclists. The pathomechanics and association of risk factors of lumbar spine overuse injuries in cycling are not clearly understood. To determine whether relationships exist between body positioning, spinal kinematics, and muscle activity in active cyclists with nontraumatic low back pain. In August of 2015 and April of 2016, a comprehensive search of the PubMed, CINAHL, Ovid MEDLINE, and Scopus databases was performed independently by 5 reviewers. Included articles consisted of biomechanical studies examining factors relating to low back pain in cyclists as agreed upon by group consensus. Systematic review. Level 4. Five reviewers appraised by consensus each article using the Downs and Black checklist. Eight studies met criteria for this review. There is evidence that cyclists with lower handlebar heights displayed increased lumbosacral flexion angles during cycling. Core muscle activation imbalances, back extensor endurance deficits, and increased lumbar flexion while cycling were found to be present in cyclists with low back pain. Spinal and core muscle activation imbalances in a prolonged flexed posture associated with cycling may lead to maladaptive spinal kinematics and increased spinal stresses contributing to overuse low back pain. © 2016 The Author(s).

Previous research with men who have sex with men (MSM) has found that substance use with sex is strongly associated with HIV acquisition and poor adherence to HIV treatments. Although some studies have assessed male couples' use of substances with unprotected anal sex, little is known on whether differences in their relationship dynamics are associated with their usage. Current HIV prevention initiatives underscore the importance of studying male couples' relationship dynamics. Using dyadic data from 28 HIV-positive and 58 HIV-discordant male couples, this analysis sought to: (1) describe, by substance type, whether neither, one, or both partners in the couple used a particular substance with sex within their relationship or outside of the relationship, respectively, and (2) assess, by substance type, whether relationship characteristic differences existed between these three groups of couples with respect to substance use with sex within and outside the relationship. Data from 86 dyads came from a cross-sectional, Internet study. Multivariate multinomial regression models were employed to achieve the aims. Except for alcohol, most did not use substances with sex. Within the relationship, those who used with sex varied by substance type; outside the relationship, most couples had only one partner who used with sex regardless of substance type. Several relationship characteristic differences were noted between the groups of couples. Within the relationship, marijuana and erectile dysfunction medication (EDM) use with sex was associated with having less tangible resources; for outside the relationship, these were associated with perceiving to have greater quality of alternatives. In general, amyl nitrates and party drug use with sex were associated with viewing the main partner as being less dependable for trustworthiness. Marijuana and party drug use with sex within the relationship and EDM use with sex outside the relationship were negatively associated with being
Global Reporting Initiative (GRI as recognized guidelines for sustainability reporting by Spanish companies on the IBEX 35: homogeneity in their framework and added value in the relationship with financial entities

Design/Methodology/Approach: In this paper we analyse the non financial reporting disclosed in the last two years (2010 and 2011 by all the companies listed on the Spanish IBEX 35 in 2010. The methodology has been based on the study of the non financial reporting available in the web sites of the analysed companies. Findings: The conclusions obtained highlight that the Global Reporting Initiative sustainability reporting framework has been mostly adopted by the studied firms as a global accepted standard in this non financial reporting and as the most important guidelines to standardize these issues. From this same descriptive point of view, we conclude that non financial entities which disclose have increased or maintained in a majority their banks´ balance sheet positions. Originality/Value: Disclosure of non financial information has been a miscellaneous of different practices depending on multiple variables. Nowadays this paper seeds some light in this subject in the way to the comparison and homogeneity of sustainability reporting and its relationship with other firms´ characteristics. Research limitations: This study is based on acceptance as a first step although must be completed with a deeper analysis of the content and its adequacy to the stakeholders´ information requirements. So, this is a descriptive analysis as a first step to go on researching in this field.

Full Text Available There is now an increasing trend of mundane and fashionable world to live together in with the environment, to spend more time in nature, to be closer to all that is unpolluted, peaceful and less known. Tourists requiring nature holidays in rural areas are becoming more and more. Ecotourism in the countryside or in the full nature is increasingly desired by people who live in urban areas with a high financial situation, but stressed out, eager to return to the nature, to the life in rural communities. Ecotourism, sustainable tourism and slow travel- all this forms of tourism have common points in terms of quality of time spent by tourists on holiday and allow them to appreciate a holiday spent far more profound, enabling them to return to long forgotten places and traditions, especially for tourists who come from highly developed countries or in those areas where they only partially preserved traditions and customs, living conditions.

Restoration of limestone quarries in arid environments mainly consists of regenerating a highly degraded soil and/or creating a soil-like substrate with minimal physico-chemical and biological properties. In an experimental soil restoration in limestone quarries from Sierra de Gádor (Almería), SE Spain, with the aim to improve soil/substrate properties and to reduce evaporation and erosion, 18 plots 15 x 5 m were prepared to test organic amendments (sludge, compost, control) and different mulches (gravel, chopped forest residue, control). In order to evaluate the soil quality of the different treatments, their chemical, physical and biological properties were analyzed. Among the most efficient biological indicators are arbuscular mycorrhizal fungi (AMF). AMF play an important role in aggregate stability due to the production of a glycoprotein called glomalin. Therefore, the aim of this study was to quantify, 5 years after the start the experiment, the content of total glomalin (TG) and to analyze its relationship with other soil parameters such as organic matter (OM) and aggregate stability soil (AE). Results indicated a remarkable effect of organic amendments on glomalin content, which was higher in the treatments with compost (6.96 mg g -1) than in sludge and control (0.54 and 0.40 mg g-1, respectively). Amendments also significantly influenced aggregate stability: the highest values were recorded in treatments with sludge and compost (23.14 and 25.09%, respectively) compared to control (13.37%). The gravel mulch had a negative influenced on AE: an average of 16% compared to 23.4% for chopped forest residues and 23.1% of control. Data showed a positive and significant correlation between values of TG and OM content (r = 0.95). We also found a positive and significant correlation between abundance of TG and AE when OM contents were lower than 4% (r = 0.93), however, there was no significant correlation to higher OM when it was higher than 4% (r = 0.34).

To investigate the change trajectories of positive and negative moods and their relationship to work ability, self-rated health, and life satisfaction in a three-wave 13-year follow-up study. The data, consisting of Finnish firefighters (n = 360), were collected via questionnaires in 1996, 1999, and 2009. Four distinct mood trajectories were identified by latent class growth modeling: (1) high positive, (2) high positive but decreasing, (3) moderately positive, and (4) high negative. The trajectory groups were differentially related to well-being. Members of the high positive trajectory had better well-being than members of other latent mood trajectories. Different trajectories exist in positive and negative moods, and these trajectories are differentially related to well-being. Developing work environments in which a positive mood can flourish is beneficial in terms of better well-being among employees.

Full Text Available Sustained attention has previously been shown as a requirement for language production. However, this is mostly evident for difficult conditions, such as a dual-task situation. The current study provides corroborating evidence that this relationship holds even for simple picture naming. Sustained attention ability, indexed both by participants’ reaction times and individuals’ hit rate (the proportion of correctly detected targets on a digit discrimination task, correlated with picture naming latencies. Individuals with poor sustained attention were consistently slower and their RT distributions were more positively skewed when naming pictures compared to individuals with better sustained attention. Additionally, the need to sustain attention was manipulated by changing the speed of stimulus presentation. Research has suggested that fast event rates tax sustained attention resources to a larger degree than slow event rates. However, in this study the fast event rate did not result in increased difficulty, neither for the picture naming task nor for the sustained attention task. Instead, the results point to a speed-accuracy trade-off in the sustained attention task (lower accuracy but faster responses in the fast than in the slow event rate, and to a benefit for faster rates in the picture naming task (shorter naming latencies with no difference in accuracy. Performance on both tasks was largely comparable, supporting previous findings that sustained attention is called upon during language production.

It is widely reported that osteocalcin is negatively associated with fat mass. However, there are few reports describing its correlation with fat-free mass, particularly in women. The objective of the current study was to investigate the possible relationship between osteocalcin and fat-free mass in healthy, nonobese women. This study was performed in a tertiary university teaching hospital. A total of 504 healthy women aged 20-75 years were enrolled. Body composition was measured using a bioelectronics impedance analyzer. The serum concentrations of total osteocalcin, estradiol, leptin, osteoprotegerin, the receptor activator of nuclear factor-κB ligand, IGF-I, fasting plasma glucose, and urinary N-terminal telopeptide of type I collagen were tested. The bone mineral densities (BMDs) at the lumbar spine and proximal femoral neck were measured by dual-energy X-ray absorptiometry. The serum total osteocalcin level had a significant positive association with fat-free mass (r = 0.168, P = .007) after adjusting for age, fat mass, menopausal status, estradiol, fasting glucose, leptin, osteoprotegerin, receptor activator of nuclear factor-κB ligand, IGF-I, N-terminal telopeptide of type I collagen, BMDs, and waist and hip circumference. Analysis in pre- and postmenopausal women demonstrated that this association was only present in premenopausal women (r = 0.190, P = .005). The multiple stepwise regression analysis revealed that hip circumference, femoral neck-BMD, fat mass, leptin, osteocalcin, and age are the contributors to the changes in fat-free mass in premenopausal women (adjusted R(2) = 0.521, P independent of age, fat mass, leptin, and other confounders in premenopausal women.
The Long-Term Benefits of Positive Self-Presentation via Profile Pictures, Number of Friends and the Initiation of Relationships on Facebook for Adolescents’ Self-Esteem and the Initiation of Offline Relationships
Full Text Available Social networking sites are a substantial part of adolescents’ daily lives. By using a longitudinal approach the current study examined the impact of (a positive self-presentation, (b number of friends, and (c the initiation of online relationships on Facebook on adolescents’ self-esteem and their initiation of offline relationships, as well as the mediating role of positive feedback. Questionnaire data were obtained from 217 adolescents (68% girls, mean age 16.7 years in two waves. Adolescents’ positive self-presentation and number of friends were found to be related to a higher frequency of receiving positive feedback, which in turn was negatively associated with self-esteem. However, the number of Facebook friends had a positive impact on self-esteem, and the initiation of online relationships positively influenced the initiation of offline relationships over time, demonstrating that Facebook may be a training ground for increasing adolescents’ social skills. Implications and suggestions for future research are provided.

Inflammation plays an integral part in tumor initiation. Specifically, patients with colitis, pancreatitis, or hepatitis have an increased susceptibility to cancer. The activation, mutation, and overexpression of oncogenes have been well documented in cell proliferation and transformation. Recently, oncogenes were found to also regulate the inflammatory milieu in tumors. Similarly, the inflammatory milieu can promote oncogene activation. In this review, we summarize advances of the symbiotic relationship oncogene activation and inflammation in gastrointestinal tumors such as colorectal, hepatic, and pancreatic tumors. NF-κB and STAT3 are the two most common pathways that are deregulated via these oncogenes. Understanding these interactions may yield effective therapeutic strategies for tumor prevention and treatment. PMID:24821201

Integrating theory on close relationships and intergroup relations, we construct a manipulation of similarity that we demonstrate can improve interracial interactions across different settings. We find that manipulating perceptions of similarity on self-revealing attributes that are peripheral to the interaction improves interactions in cross-race dyads and racially diverse task groups. In a getting-acquainted context, we demonstrate that the belief that one's different-race partner is similar to oneself on self-revealing, peripheral attributes leads to less anticipatory anxiety than the belief that one's partner is similar on peripheral, nonself-revealing attributes. In another dyadic context, we explore the range of benefits that perceptions of peripheral, self-revealing similarity can bring to different-race interaction partners and find (a) less anxiety during interaction, (b) greater interest in sustained contact with one's partner, and (c) stronger accuracy in perceptions of one's partners' relationship intentions. By contrast, participants in same-race interactions were largely unaffected by these manipulations of perceived similarity. Our final experiment shows that among small task groups composed of racially diverse individuals, those whose members perceive peripheral, self-revealing similarity perform superior to those who perceive dissimilarity. Implications for using this approach to improve interracial interactions across different goal-driven contexts are discussed.
Full Text Available In this study, the relationship between environmental innovation and sustainability is analyzed in 168 handicraft businesses in the Mexican states of Oaxaca, Puebla, and Tlaxcala. The results show a direct, positive relationship between environmental innovation and sustainability in three dimensions: economic, social, and environmental. In terms of determination, the variables that best explain sustainability are: organization type, product innovation, and process innovation. The age of the handicraft businesses was not a significant factor in explaining sustainability. This study concludes that handicraft businesses make sustainable choices more as a result of a desire for profit maximization than as a result of environmental consciousness, as can be explained by neoclassical view of economics.

Full Text Available A Sustainable Competitive Advantage emerges as an important factor in the perception of value of goods and services, which should be considered as elements of competitive differentiation. This study aims at identifying the relationship between sustainable competitive advantage and organizational performance, as well as measuring the relationship of environmental sustainability and social responsibility as attributes of sustainable competitive advantage. In order to achieve that, a survey was carried out in 1496 different size companies and activity sectors in Brazil. For the data analysis and interpretation we used a structural equation modeling technique. The results indicate that the Sustainable Competitive Advantage construct is an important antecedent of organizational performance because it highlights fundamental attributes for organizations to achieve positive economic consequences. This research contributes to organizational management and to the scientific community with the provision of a framework that assists in the identification of relevant strategic resource features.

We analyzed plants that are traditionally used by wild bird hunters and breeders to capture and promote captive breeding of Fringillidae (finches or songbirds) in the province of Alicante, Spain. The majority of plants used in songbird breeding have medicinal properties in traditional human medicine (48 different uses); thus, another main goal was to show their relationships with human medical uses. We compiled a list of 97 plant species from 31 botanical families that are used to attract finches and identified 11 different use categories for these plants in finch keeping. The most common uses were for trapping birds and as a source of food for birds in captivity. Cannabis sativa has the greatest cultural importance index (CI = 1.158), and Phalaris canariensis (annual canary grass or alpist) was the most common species used to attract Fringillidae and was used by all informants (n = 158). Most of the 97 species are wild plants and mainly belong to the families Compositae, Gramineae, Cruciferae, and Rosaceae and also have medicinal properties for humans. In the study area, the intensification of agriculture and abandonment of traditional management practices have caused the population of many songbirds to decline, as well as the loss of popular ethnographic knowledge.

Full Text Available It can be stated from the previous research that positive emotions should allow to better health outcomes in sick populations. The aim of the present work is to know the state-of-the-art of how positive affect (PA relates with quality of life in colorectal cancer (CRC patients, as well as to give some guidelines to develop more efficacious psychological interventions in CRC patients to enhance positive affect. This review describes a search of published literature from January 2001 to March of 2012 on the Medline, ISI Web of Knowledge, Psycho Inf and Cochrane databases using publications that contain positive emotions, positive affect, health outcomes, quality of life, CRC and cancer. These articles were classified into two groups: a "descriptive papers" b "interventional studies". Results from "descriptive papers" suggest that positive affect (PA was significantly associated with greater levels of general health, better social functioning, benefit finding, positive changes, low depression, less anxiety and greather psychological well-being. PA also increases when different activities are developed. The overall results from interventional studies suggest that the interventions described can be recommended for improving patient's levels of positive affect. The present review offers some suggestions which could be useful for CRC patients.

Full Text Available Companies have to communicate to be noticed on the market, to promote their services and products, and to give assurances that they are a credible partner in the relationship with stakeholders. In this article, starting from the importance of marketing communication in business, an index of sustainability communication was created for the companies listed on the Bucharest Stock Exchange for the period 2008–2009, during the financial crisis, seeking to show the awareness of the difficult moment and the use of communication. Then, based on the relevance of accounting information model, we study the relationship between the index of sustainability communication and the share price, basically its influence on the future performance of the company. The regression analysis emphasizes the positive influence of the index of sustainability communication on the share price.

Recent correlational evidence implicates gratitude in personal and relational growth, for both members of ongoing relationships. From these observations, it would be tempting to prescribe interpersonal gratitude exercises to improve relationships. In this experiment, couples were randomly assigned to express gratitude over a month, or to a relationally-active control condition. Results showed modest effects of condition on personal and relational well-being. However, those whose partners were perceived as being particularly responsive when expressing gratitude at the initial lab session showed greater well-being across a range of outcomes, whereas this was not so for people in the control condition. Notably, evidence raises concerns about the effectiveness of artificial injections of gratitude when the partner is perceived to be low in responsiveness. Given the importance of close relationships, this work highlights the need for more theory-driven basic research tested in context before assuming what appears to work naturally will also work artificially.

The purpose of this study was to investigate whether stress sensitivity mediates the relationship between traumatic life events and total attenuated positive psychotic symptoms, as well as the relationship between traumatic life events and endorsement of 8 or more attenuated positive psychotic symptoms as distressing (a threshold that has been associated with higher risk for psychosis in clinical groups). Participants (n = 671, aged 17-35, 29% male) were college students who were administered the Prodromal Questionnaire, the Perceived Stress Scale and the Life Events Checklist. Bootstrapping results indicated that stress sensitivity significantly mediated the relationships between traumatic life events and the number of attenuated positive psychotic symptoms endorsed and between traumatic life events and those who endorsed 8 or more distressing attenuated positive psychotic symptoms. Stratified gender analyses indicated the findings were specific to females. Results suggest that stress sensitivity may represent a specific vulnerability factor for risk of attenuated psychotic symptoms in those previously exposed to traumatic life events and that this liability appears stronger in females.

Full Text Available Affects are composed of two key dimensions: the positive affect (PA and negative affect (NA. Both dimensions are related to psychological adjustment of the person and life satisfaction. This study is exploratory in nature and aims to make a first correlational analysis between different constructs: emotional disposition, academic achievement, mental health and life satisfaction in a sample of 143 student teachers. We have used the following scales adapted to the culture: The Positive and Negative Affect Schedule (PANAS, the Mental Health Inventory (MHI-5 and the Satisfaction With Life Scale (SWLS. Among the most interesting results it was found that positive affect was associated with academic achievement, mental health and life satisfaction. Positive and negative affects and satisfaction with life were formed as predictors of future teachers’ mental health. Extensive analysis and discussion of the results is included in the document.

Overnight oxyhaemoglobin desaturation is related to AMS. AMS can be debilitating and may require descent. Positive pressure ventilation during sleep at high altitude may prevent AMS and therefore be useful in people travelling to high altitude, who are known to suffer from AMS. Ascent to high altitude results in hypobaric hypoxia and some individuals will develop acute mountain sickness (AMS), which has been shown to be associated with low oxyhaemoglobin saturation during sleep. Previous research has shown that positive end-expiratory pressure by use of expiratory valves in a face mask while awake results in a reduction in AMS symptoms and higher oxyhaemoglobin saturation. We aimed to determine whether positive pressure ventilation would prevent AMS by increasing oxygenation during sleep. We compared sleeping oxyhaemoglobin saturation and the incidence and severity of AMS in seven subjects sleeping for two consecutive nights at 3800 m above sea level using either non-invasive positive pressure ventilation that delivered positive inspiratory and expiratory airway pressure via a face mask, or sleeping without assisted ventilation. The presence and severity of AMS were assessed by administration of the Lake Louise questionnaire. We found significant increases in the mean and minimum sleeping oxyhaemoglobin saturation and decreases in AMS symptoms in subjects who used positive pressure ventilation during sleep. Mean and minimum sleeping SaO2 was lower in subjects who developed AMS after the night spent without positive pressure ventilation. The use of positive pressure ventilation during sleep at 3800 m significantly increased the sleeping oxygen saturation; we suggest that the marked reduction in symptoms of AMS is due to this higher sleeping SaO2. We agree with the findings from previous studies that the development of AMS is associated with a lower sleeping oxygen saturation.

To analyze the influence of the Kangaroo Position duration in the initial interactions between mothers and preterm infants. This is an exploratory prospective observational study that analyzed the mother-infant interaction during breastfeeding, before hospital discharge. All eligible newborns, with a gestational age of 28-32 weeks and a birth weight of 1,000-1,800 g from June 11 to September 31, 2014 were included. The films of the interaction were evaluated by the "Mother-Baby Interaction Protocol 0-6 months" tool. The duration of the Kangaroo Position during all the hospitalization period was correlated with the interaction between mother and preterm infant. The longer the dyad spent time in the Kangaroo Position, the more the newborns made physical contact attempts with their mothers during breastfeeding (r=0.37; p=0.03); and the longer the time in the Kangaroo Position, the less the mothers talked to their children (r=-0.47; p=0.006). Longer periods in the Kangaroo Position stimulates the initial exchanges of contact between preterm infant with his mother, which suggests a higher alert status of the newborn and a better availability for interactions with the mother during breastfeeding.
Full Text Available This research was aimed at determining the relationship between the social anxiety and the body dysmorphic disorder with mediation of fear of positive and negative evaluation. The research method was descriptive and had correlational pattern in which the structural equation modelling was utilized. The research community included the female bachelor and master students, being studied at Imam Khomeini International University, Qazvin, Iran, in 2015-2016 academic year. In this research, 1000 students, selected based on clustering random sampling, have answered the questionnaires and then 280 students were selected as the final samples based on the purposive sampling. The research tools composed of body dysmorphic metacognitive evaluation, social phobia inventory, Leary’s brief version of fear of negative evaluation, and fear of positive evaluation. The data of subjects were analyzed using path analysis, confirmatory factor analysis, measurement model test and structural model test. The results stated that the fear of positive and negative evaluation together mediates the relationship between the social anxiety and the body dysmorphic disorder. In addition, the direct effect of social anxiety on the fear of positive evaluation, on the fear of negative evaluation and on the body dysmorphic disorder was affirmed. Therefore, the interventions that target the fear of positive and negative evaluation as the central components of social anxiety can help the prevention of growth in body dysmorphic disorder

Previous studies have reported conflicting results regarding the relationship between individuality and social identity, indicating this area requires further examination. This study constructed a research model to help understand the positive role of individualized behavior and social identity in virtual communities. The results of an online survey conducted to assess our theoretical research model indicated that social identity can be expressed in two ways: self-categorization and social identification. Furthermore, we found individualized behavior was positively related to social identification, while self-categorization was directly derived from social identification.

The main aims of this research were to test the similarity of masculinity-femininity in long-term male same-sex couples from the Czech Republic and to examine whether this similarity predicts higher relationship quality. In Study 1, participants (N = 30) and their partners completed the Dyadic Adjustment Scale (DAS) and the Childhood Gender Nonconformity Scale (CGN). In Study 2, participants (N = 40) and their partners completed DAS and the Gender Diagnosticity Scale (GD). Results showed that the partners were no more alike than individuals paired at random in their CGN or GD, but greater similarity in CGN between partners increased Dyadic Cohesion (r = -.41 [-.71, -.02]) and Affectional Expression (r = -.38 [-.60, -.13]). Our results add to previous evidence showing that similarity in same-sex couples increased relationship quality. Although, on average, gay men were not coupled on the basis of homogamy in gender roles, their relationship quality is linked to the gender egalitarian model rather than to the gender stratified one. Thus, a widespread stereotype suggesting that same-sex partners are divided by different gender roles seems to be, at least in our sample from a Western society, rather incorrect.

The current study examined the role of naturally-occurring negative and positive emotion expressivity in kindergarten and children's effortful control (EC) on their relationships with teachers, academic engagement, and problems behaviors in school. Further, the potential moderating role of EC on these important school outcomes was assessed. Emotion and engagement were observed at school. EC was assessed by multiple methods. Teachers reported on their student-teacher relationships and student's externalizing behaviors. Children's emotion expressivity and EC were related to engagement and relationships with teachers as well as behavioral problems at school. Children low in EC may be particularly vulnerable to the poor outcomes associated with relatively intense emotion expressivity as they struggle to manage their emotions and behaviors in the classroom.

In some studies, situational factors have been shown to be stronger predictors of condomless sex than individual risk factors. Cross-sectional relationships between condomless anal sex (CAS) with HIV-serodiscordant partners and risk factors across ecological levels (individual, sexual environment) were examined using a sample (N = 60) of HIV-positive men who have sex with men (MSM) who reported multiple recent episodes of CAS. Negative binomial regressions were used to evaluate the associatio...

The Bivalent Fear of Evaluation (BFOE) model of social anxiety proposes that fear of negative evaluation (FNE) and fear of positive evaluation (FPE) play distinct roles in social anxiety. Research is however lacking in terms of how FPE is related to perfectionism and how these constructs interact to predict social anxiety. Participants were 382 individuals from the general community and included an oversampling of individuals with social anxiety. Measures of FPE, FNE, perfectionism, and social anxiety were administered. Results were mostly consistent with the predictions made by the BFOE model and showed that accounting for confounding variables, FPE correlated negatively with high standards but positively with maladaptive perfectionism. FNE was also positively correlated with maladaptive perfectionism, but there was no significant relationship between FNE and high standards. Also consistent with BFOE model, both FNE and FPE significantly moderated the relationship between maladaptive perfectionism and social anxiety with the relationship strengthened at high levels of FPE and FNE. These findings provide additional support for the BFOE model and implications are discussed.

Sustainability is the theme of our time and also the grandest challenge to humanity. Since the 1970s, the term, sustainable development, has frequently appeared in the scientific literature, governmental documents, media promotions for public goods, and commercial advertisements. However, the science that provides the theoretical foundation and practical guidance for sustainable development--sustainability science--only began to emerge in the beginning of the 21st century. Nevertheless, the field has rapidly developed in depth and expanded in scope during the past decade, with its core concepts and research methods coalescing. China, as the most populous country in the world and home to the philosophical root of sustainability science-the unity of man and nature, is obligated to take upon the challenge of our time, to facilitate global sustainability while pursuing the Chinese Dream, and to play a leading role in the development of sustainability science. Toward this grandiose goal, this paper presents the first Chinese introduction to sustainability science, which discusses its basic concepts, research questions, and future directions. Sustainability science is the study of the dynamic relationship between humans and the environment, particularly focusing on the vulnerability, robustness, resilience, and stability of the coupled human-environment system. It is a transdisciplinary science that integrates natural sciences with humanities and social sciences. It hinges on the environment-economy-society nexus, and merges basic and applied research. The key components of sustainability often change with time, place, and culture, and thus sustainability science needs to emphasize multi-scale studies in space and time, with emphasis on landscapes and regions over a horizon of 50 to 100 years. It needs to focus on the relationship between ecosystem services and human well-being, as influenced by biodiversity and ecosystem processes as well as climate change, land use

Full Text Available Soldiering is defined as engaging behaviourally or cognitively into non-work-related activities during working hours with no intention of harming the employer, co-workers, and/or clients. The present study will investigate this phenomenon using the Job-Demands Resources Model. The proposed model will consider the influence of job demands and resources on soldiering, as well as the relationship of soldiering with employee wellbeing and performance. The data, collected via online questionnaires across seven European countries, will be analysed using structural equation modelling in order to explore the goodness-of-fit of the proposed model as well as its potential cross cultural variations.

The purpose of the study was to investigate the relationships between the Myers-Briggs Type Indicator (MBTI) psychological type and marital satisfaction, divorce proneness, positive affect, and conflict regulation in couple visiting a clinic. Couples (n=62) who visited "M" couple clinic participated in the study. Data were collected from March to June 2009 using the Marital Satisfaction Scale, Marital Status Inventory, Positive Affect Inventory, and Conflict Regulation Inventory. The couples showed no significant differences in marital satisfaction, positive affect, and conflict regulation according to similarities between spouses in MBTI types. However, they showed significant differences in divorce proneness of husband according to a similarity in the Sensing/Intuition indicator. They also showed significant differences in divorce proneness, positive affect, and conflict regulation between the couples for ISTJ (Introversion, Sensing, Thinking, Judging) or ESTJ (Extraversion, Sensing, Thinking, Judging) types compared to other couples. When nurses counsel couples, they should understand that differences in psychological type between spouses affects their marital relationship. In addition, nurses should educate couples on the characteristics of each type according to the couple's types and help them to understand each other, especially for couples where one spouse is the ISTJ/ESTJ type. These interventions will improve marital satisfaction and prevent the divorce in these couples.

Few longitudinal studies considered positive mental wellbeing outcomes. We addressed this gap using Medical Research Council National Survey of Health and Development (NSHD) data. Wellbeing was measured at ages 13-15 (teacher-rated happiness), 36 (life satisfaction), 43 (satisfaction with home and family life), and 60-64 years (Diener Satisfaction With Life scale and Warwick Edinburgh Mental Wellbeing Scale). The Parental Bonding Instrument captured perceived care and control from the father ...

Why does self-control predict such a wide array of positive life outcomes? Conventional wisdom holds that self-control is used to effortfully inhibit maladaptive impulses, yet this view conflicts with emerging evidence that self-control is associated with less inhibition in daily life. We propose that one of the reasons individuals with better self-control use less effortful inhibition, yet make better progress on their goals is that they rely on beneficial habits. Across six studies (total N...

There has been limited study of whether and for whom physical intimate partner violence (IPV) is a consequence of an HIV-positive diagnosis. Per the diathesis stress model, the consequences of HIV infection may be worse for women with a history of IPV. We hypothesize that the positive association between HIV diagnosis in pregnancy and postpartum IPV will be exacerbated for women with a history of IPV. Data come from a prospective cohort study with 1015 participants who completed a baseline antenatal and 9-month postpartum visit. Using logistic regression analyses, we found a statistically significant interaction between HIV diagnosis, history of IPV and postpartum IPV (AOR: 0.40, 95% CI 0.17-0.96). The findings were in the opposite direction as expected: HIV-diagnosis was not associated with IPV for women with a history of IPV (AOR: 2.17, 95% CI 1.06, 4.42). However, HIV-positive women without a history of IPV faced more than two times the risk of incident postpartum IPV than HIV-negative women (AOR: 2.17, 95% CI 1.06, 4.42). Interventions to reduce incident and ongoing IPV during the perinatal period are needed.

Full Text Available Personal and shared vision have a long history in management and organizational practices yet only recently have we begun to build a systematic body of empirical knowledge about the role of personal and shared vision in organizations. As the introductory paper for this special topic in Frontiers in Psychology, we present a theoretical argument as to the existence and critical role of two states in which a person, dyad, team, or organization may find themselves when engaging in the creation of a personal or shared vision: the positive emotional attractor (PEA and the negative emotional attractor (NEA. These two primary states are strange attractors, each characterized by three dimensions: (1 positive versus negative emotional arousal; (2 endocrine arousal of the parasympathetic nervous system versus sympathetic nervous system; and (3 neurological activation of the default mode network versus the task positive network. We argue that arousing the PEA is critical when creating or affirming a personal vision (i.e., sense of one’s purpose and ideal self. We begin our paper by reviewing the underpinnings of our PEA-NEA theory, briefly review each of the papers in this special issue, and conclude by discussing the practical implications of the theory.

Many authors have proposed the necessity of the design and implementation of dietary and nutrition education programs for soccer players, although little information is available about the determinants of food selection and nutrient intake. The aim of this study was to evaluate the nutritional intake and eating patterns of soccer players according to their playing position in the team. Eighty-seven young male soccer players (aged 16-21 years) were recruited from the junior teams of a Spanish First Division Soccer League Club and divided into 6 positional categories (goalkeepers, full-backs, centre-backs, midfielders, wingers, and forwards). Body composition (height, weight, and body fat), performance in soccer-specific tests (jumping, sprinting, and intermittent endurance), and dietary intake (weighed food intake method) were assessed. A spontaneous higher carbohydrate intake was observed for full-backs, midfielders, and wingers (g·kg(-1) body mass: 4.9 ± 1.0, 4.9 ± 1.3, 4.9 ± 0.8; % of energy intake: 47 ± 5, 46 ± 6, 46 ± 4), compared with goalkeepers and centre-backs (g·kg(-1) of body mass: 3.9 ± 1.0, 4.3 ± 1.1; % of energy intake: 44 ± 3, 42 ± 4). These differences were related to food selection patterns, and a higher contribution to daily energy intake of cereals, derivatives, and potatoes was observed between full-backs compared with goalkeepers and centre-backs (33% vs. 27% and 25%). The magnitude of these differences is limited considering the whole diet, and an inadequate nutrient intake were observed in most individuals of every group. The design and implementation of nutrition intervention programs, taking into consideration positional differences in nutritional intake, would be useful for these players.

This article adds to a small, but growing, body of work on trans sexualities and partnerships, and provides a much-needed inquiry into the complex and contested politics of desire when we take trans identities, bodies, and sexualities into account. Using digital ethnographic data from YouTube videos along with in-person observational data from LGBTQ and trans conferences in the U.S., Tompkins argues that a sex-positive trans politics cannot emerge in trans and trans-allied communities if the rhetoric of the "tranny chaser" continues to inform discourses of desire and attraction to trans people.

RUNX1 plays opposing roles in breast cancer: a tumor suppressor in estrogen receptor-positive (ER+) disease and an oncogenic role in ER-negative (ER-) tumors. Potentially mediating the former, we have recently reported that RUNX1 prevents estrogen-driven suppression of the mRNA encoding the tumor suppressor AXIN1. Accordingly, AXIN1 protein expression was diminished upon RUNX1 silencing in ER+ breast cancer cells and was positively correlated with AXIN1 protein expression across tumors with high levels of ER. Here we report the surprising observation that RUNX1 and AXIN1 proteins are strongly correlated in ER- tumors as well. However, this correlation is not attributable to regulation of AXIN1 by RUNX1 or vice versa. The unexpected correlation between RUNX1, playing an oncogenic role in ER- breast cancer, and AXIN1, a well-established tumor suppressor hub, may be related to a high ratio between the expression of variant 2 and variant 1 (v2/v1) of AXIN1 in ER- compared with ER+ breast cancer. Although both isoforms are similarly regulated by RUNX1 in estrogen-stimulated ER+ breast cancer cells, the higher v2/v1 ratio in ER- disease is expected to weaken the tumor suppressor activity of AXIN1 in these tumors.

Daptomycin is a highly effective lipopeptide antibiotic against Gram-positive pathogens. The presence of (2S, 3R) 3-methyl glutamic acid (mGlu) in daptomycin has been found to be important to the antibacterial activity. However the role of (2S, 3R) mGlu is yet to be revealed. Herein, we reported the syntheses of three daptomycin analogues with (2S, 3R) mGlu substituted by (2S, 3R) methyl glutamine (mGln), dimethyl glutamic acid and (2S, 3R) ethyl glutamic acid (eGlu), respectively, and their antibacterial activities. The detailed synthesis of dimethyl glutamic acid was also reported. Copyright © 2016 Elsevier Ltd. All rights reserved.

Why does self-control predict such a wide array of positive life outcomes? Conventional wisdom holds that self-control is used to effortfully inhibit maladaptive impulses, yet this view conflicts with emerging evidence that self-control is associated with less inhibition in daily life. We propose that one of the reasons individuals with better self-control use less effortful inhibition, yet make better progress on their goals is that they rely on beneficial habits. Across 6 studies (total N = 2,274), we found support for this hypothesis. In Study 1, habits for eating healthy snacks, exercising, and getting consistent sleep mediated the effect of self-control on both increased automaticity and lower reported effortful inhibition in enacting those behaviors. In Studies 2 and 3, study habits mediated the effect of self-control on reduced motivational interference during a work-leisure conflict and on greater ability to study even under difficult circumstances. In Study 4, homework habits mediated the effect of self-control on classroom engagement and homework completion. Study 5 was a prospective longitudinal study of teenage youth who participated in a 5-day meditation retreat. Better self-control before the retreat predicted stronger meditation habits 3 months after the retreat, and habits mediated the effect of self-control on successfully accomplishing meditation practice goals. Finally, in Study 6, study habits mediated the effect of self-control on homework completion and 2 objectively measured long-term academic outcomes: grade point average and first-year college persistence. Collectively, these results suggest that beneficial habits-perhaps more so than effortful inhibition-are an important factor linking self-control with positive life outcomes.

Learning environments are a significant determinant of student behaviour, achievement and satisfaction. In this article we use students' reflective essays to identify key features of the learning environment that contributed to positive and transformative learning experiences. We explore the relationships between these features, the students' sense of safety in the learning environment (LE), the resulting learning challenge with which they could cope and their positive reports of the experience itself. Our students worked in a unique simulation of General Practice, the Safe and Effective Clinical Outcomes clinic, where they consistently reported positive experiences of learning. We analysed 77 essays from 2011 and 2012 using an immersion/crystallisation framework. Half of the students referred to the safety of the learning environment spontaneously. Students described deep learning experiences in their simulated consultations. Students valued features of the LE which contributed to a psychologically safe environment. Together with the provision of constructive support and immediate, individualised feedback this feeling of safety assisted students to find their own way through clinical dilemmas. These factors combine to make students feel relaxed and able to take on challenges that otherwise would have been overwhelming. Errors became learning opportunities and students could practice purposefully. We draw on literature from medical education, educational psychology and sociology to interpret our findings. Our results demonstrate relationships between safe learning environments, learning challenge and powerful learning experiences, justifying close attention to the construction of learning environments to promote student learning, confidence and motivation.

The ordinal level phylogeny of the Arachnida and the suprafamilial level phylogeny of the Opiliones were studied on the basis of a combined analysis of 253 morphological characters, the complete sequence of the 18S rRNA gene, and the D3 region of the 28S rRNA gene. Molecular data were collected for 63 terminal taxa. Morphological data were collected for 35 exemplar taxa of Opiliones, but groundplans were applied to some of the remaining chelicerate groups. Six extinct terminals, including Paleozoic scorpions, are scored for morphological characters. The data were analyzed using strict parsimony for the morphological data matrix and via direct optimization for the molecular and combined data matrices. A sensitivity analysis of 15 parameter sets was undertaken, and character congruence was used as the optimality criterion to choose among competing hypotheses. The results obtained are unstable for the high-level chelicerate relationships (except for Tetrapulmonata, Pedipalpi, and Camarostomata), and the sister group of the Opiliones is not clearly established, although the monophyly of Dromopoda is supported under many parameter sets. However, the internal phylogeny of the Opiliones is robust to parameter choice and allows the discarding of previous hypotheses of opilionid phylogeny such as the "Cyphopalpatores" or "Palpatores." The topology obtained is congruent with the previous hypothesis of "Palpatores" paraphyly as follows: (Cyphophthalmi (Eupnoi (Dyspnoi + Laniatores))). Resolution within the Eupnoi, Dyspnoi, and Laniatores (the latter two united as Dyspnolaniatores nov.) is also stable to the superfamily level, permitting a new classification system for the Opiliones. c2002 The Willi Hennig Society.

Canine atlantooccipital overlapping (AOO) is characterized by a decreased distance between the dorsal arch of the atlas and the supraoccipital bone. Current diagnostic criteria for this condition are subjective and clinician-dependent; objective criteria are needed to allow a reliable and reproducible diagnosis in clinical and research settings and assess clinical significance. We propose four standardized MRI-based measurements to objectively assess the proximity of the atlas to the foramen magnum. Inclusion criteria for dogs in this study were bodyweight 5 months, and availability of a complete MRI study performed with the craniocervical junction in extension. Exclusion criteria were space-occupying lesions and poor image quality (i.e. unclear bony margins). Measurements also included blinded determinations of skull type, presence of craniocervical junction anomalies and presence and severity of syringomyelia. Clinical status at the time of imaging was noted. Measurements were obtained in 271 dogs; these were reproducible and reliable. Findings varied by skull type: dolichocephalic dogs had smaller foramen magnum, whereas brachycephalic dogs had more cranially and dorsally positioned atlas bodies in comparison to the other skull types. Measurements also increased with increases in bodyweight. This study demonstrated a close association between AOO, syringomyelia and clinical signs. Toy and small breed dogs (including Cavalier King Charles spaniels) showed higher than previously reported prevalence of AOO; its occurrence was also associated with lower bodyweights within the study population of <15 kg toy/small breed dogs.

Full Text Available This study examined data from 96 schools in a Southeastern U.S. state participating in training and/or coaching on School-Wide Positive Behavioral Interventions and Supports (SWPBIS provided by the State Personnel Development Grant (SPDG in their state. Schools studied either received training only (“non-intensive” sites or training and on-site coaching (“intensive” sites. Fidelity of implementation was self-evaluated by both types of schools using the Benchmarks of Quality (BOQ. Some schools were also externally evaluated using the School-Wide Evaluation Tool (SET, with those scoring 80% or higher determined “model sites.” Using an independent sample t-test, analyses revealed statistically significant differences between intensive and nonintensive schools’ Quality of Distribution Index (QDI scores and between model sites and nonmodel sites on QDI scores. Correlations were performed to determine whether the fidelity of implementation of SWPBIS as measured by the BOQ was related to any of the state’s accountability measures: performance classification, QDI, or growth.
ICT Innovations for Sustainability is an investigation of how information and communication technology can contribute to sustainable development. It presents clear definitions of sustainability, suggesting conceptual frameworks for the positive and negative effects of ICT on sustainable development. It reviews methods of assessing the direct and indirect impact of ICT systems on energy and materials demand, and examines the results of such assessments. In addition, it investigates ICT-based approaches to supporting sustainable patterns of production and consumption, analyzing them at various levels of abstraction – from end-user devices, Internet infrastructure, user behavior, and social practices to macro-economic indicators. Combining approaches from Computer Science, Information Systems, Human-Computer Interaction, Economics, and Environmental Sciences, the book presents a new, holistic perspective on ICT for Sustainability (ICT4S). It is an indispensable resource for anyone working in the area of ICT...

The inverse relationship between atmospheric CO2 partial pressure (pCO2) and stomatal frequency in many species of plants has been widely used to estimate palaeoatmospheric CO2 (palaeo-CO2) levels; however, the results obtained have been quite variable. This study attempts to find a potential new proxy for palaeo-CO2 levels by analysing stomatal frequency in Quercus guyavifolia (Q. guajavifolia, Fagaceae), an extant dominant species of sclerophyllous forests in the Himalayas with abundant fossil relatives. Stomatal frequency was analysed for extant samples of Q. guyavifolia collected from17 field sites at altitudes ranging between 2493 and 4497 m. Herbarium specimens collected between 1926 and 2011 were also examined. Correlations of pCO2-stomatal frequency were determined using samples from both sources, and these were then applied to Q. preguyavaefolia fossils in order to estimate palaeo-CO2 concentrations for two late-Pliocene floras in south-western China. In contrast to the negative correlations detected for most other species that have been studied, a positive correlation between pCO2 and stomatal frequency was determined in Q. guyavifolia sampled from both extant field collections and historical herbarium specimens. Palaeo-CO2 concentrations were estimated to be approx. 180-240 ppm in the late Pliocene, which is consistent with most other previous estimates. A new positive relationship between pCO2 and stomatal frequency in Q. guyavifolia is presented, which can be applied to the fossils closely related to this species that are widely distributed in the late-Cenozoic strata in order to estimate palaeo-CO2 concentrations. The results show that it is valid to use a positive relationship to estimate palaeo-CO2 concentrations, and the study adds to the variety of stomatal density/index relationships that available for estimating pCO2. The physiological mechanisms underlying this positive response are unclear, however, and require further research. © The
The conversion of biomass to chemicals and energy is imperative to sustaining our way of life as known to us today. Fossil chemical and energy sources are traditionally regarded as wastes from a distant past. Petroleum, natural gas, and coal are not being regenerated in a sustainable manner. However, biomass sources such as algae, grasses, bushes and forests are continuously being replenished. Woody biomass represents the most abundant and available biomass source. Woody biomass is a reliably sustainable source of chemicals and energy that could be replenished at a rate consistent with our needs. The biorefinery is a concept describing the collection of processes used to convert biomass to chemicals and energy. Woody biomass presents more challenges than cereal grains for conversion to platform chemicals due to its stereochemical structures. Woody biomass can be thought of as comprised of at least four components: extractives, hemicellulose, lignin and cellulose. Each of these four components has a different degree of resistance to chemical, thermal and biological degradation. The biorefinery concept proposed at ESF (State University of New York - College of Environmental Science and Forestry) aims at incremental sequential deconstruction, fractionation/conversion of woody biomass to achieve efficient separation of major components. The emphasis of this work is on the kinetics of hot-water extraction, filling the gap in the fundamental understanding, linking engineering developments, and completing the first step in the biorefinery processes. This first step removes extractives and hemicellulose fractions from woody biomass. While extractives and hemicellulose are largely removed in the extraction liquor, cellulose and lignin largely remain in the residual woody structure. Xylo-oligomers and acetic acid in the extract are the major components having the greatest potential value for development. Extraction/hydrolysis involves at least 16 general reactions that could
Full Text Available The aim of this work was to give an evidence of the likely presence of interstitial cells in the canine lower urinary tract and to study their possible interactions with the musculature and the intramural innervation. Cryosections of normal canine bladder and urethra were immunofluorescently labelled with c-kit, a transmembrane, tyrosine kinase growth factor receptor, known to be expressed on the interstitial cells of Cajal (ICCs of the gut. The relationship with antiactin positive smooth muscle cells and PGP9.5-positive intramural innervation was also investigated by confocal microscopy. Anti-c-kit labelling demonstrated a network of elongated and branched c-kit positive cells, which were located in interstitial spaces, oriented in parallel to the smooth muscle bundles that form the bladder muscular layer, irrespective of dog sex. Cells with a similar localization were also PAS- and NADPH-diaphorase-positive. A contact between c-kit immunofluorescent cells and intramural innervation was demonstrated, too. The roles of interstitial cells might include regulation of smooth muscle activity of the bladder detrusor, integrating neuronal signals during urine storage and voiding.

The aim of this study is to demonstrate the validity of the Rorschach Perceptual Thinking Index (PTI) in the assessment of reality testing in patients with psychosis. We evaluated the relationship between the PTI criteria and the Positive and Negative Syndrome Scale (PANSS) scores in 98 psychotic disorder affected patients. Thirty four were evaluated during the acute episode (AP) and 64 were chronically treated and stable (CP). The PANSS positive score resulted significantly higher in AP than in CP group, but no significant difference was found in the PTI score. The PTI positively correlated with the PANSS total score. The PTI1 and PTI2 criteria significantly correlated with the PANSS negative score, the PTI4 and PTI5 with the positive. The Rorschach variable X-% significantly correlated with the negative symptoms; the WSum6 with thought disorders; and the M- with delusions. PTI score, X-% and WSum6 predicted impaired judgment and insight. These results suggest that PTI is a valid instrument to assess impairment in reality testing, regardless of the patient׳s current psychiatric presentation. The presence of conceptual disorganization, delusions, lack of judgment and insight don׳t have effects on the PTI, supporting its strength as an assessment tool for psychotic disorders.

To determine if positive emotion modifies the relationship between cognitive impairment and activities of daily living disability status over 10 years in Mexican American adults aged 75 years and older. A retrospective cohort design using data from the Hispanic established populations for the epidemiologic studies of the elderly. About 2674 participants aged 75 years and older were included and followed over 10 years. Cognition was measured using the mini-mental state examination, positive emotion was measured using four questions from the Center for Epidemiologic Studies Depression Scale, and disability was measured using seven activities of daily living items. A series of generalized estimating equations models were used, with the initial analysis including those with disability at baseline and subsequent analyses excluding disability at baseline. Positive emotion and cognitive impairment consistently decreased and increased risk for activities of daily living disability, respectively. Positive emotion was a significant modifier in the cross-sectional analysis, and was not a statistically significant modifier in the longitudinal or predictive series analysis. Positive emotion and cognitive impairment differentially affect the risk of developing activities of daily living disability. Further research is needed to explore the interaction of positive emotion and cognitive impairment, and to identify appropriate interventions that address the specific cognitive and emotional needs of older Mexican Americans. Implications for rehabilitation Promoting emotional well-being may be protective against incident disability for older adults. Cognitive impairment significantly predicts incident disability in activities of daily living and should be considered an early indicator of impending disability for older adults.

PURPOSE To determine whether plasma estradiol (E2) levels are related to gene expression in estrogen receptor (ER)-positive breast cancers in postmenopausal women. Materials and METHODS Genome-wide RNA profiles were obtained from pretreatment core-cut tumor biopsies from 104 postmenopausal patients with primary ER-positive breast cancer treated with neoadjuvant anastrozole. Pretreatment plasma E2 levels were determined by highly sensitive radioimmunoassay. Genes were identified for which expression was correlated with pretreatment plasma E2 levels. Validation was performed in an independent set of 73 ER-positive breast cancers. Results The expression of many known estrogen-responsive genes and gene sets was highly significantly associated with plasma E2 levels (eg, TFF1/pS2, GREB1, PDZK1 and PGR; P < .005). Plasma E2 explained 27% of the average expression of these four average estrogen-responsive genes (ie, AvERG; r = 0.51; P < .0001), and a standardized mean of plasma E2 levels and ER transcript levels explained 37% (r, 0.61). These observations were validated in an independent set of 73 ER-positive tumors. Exploratory analysis suggested that addition of the nuclear coregulators in a multivariable analysis with ER and E2 levels might additionally improve the relationship with the AvERG. Plasma E2 and the standardized mean of E2 and ER were both significantly correlated with 2-week Ki67, a surrogate marker of clinical outcome (r = -0.179; P = .05; and r = -0.389; P = .0005, respectively). CONCLUSION Plasma E2 levels are significantly associated with gene expression of ER-positive breast cancers and should be considered in future genomic studies of ER-positive breast cancer. The AvERG is a new experimental tool for the study of putative estrogenic stimuli of breast cancer.

The incidence of HIV-related non-Hodgkin lymphoma (NHL) but not that of Hodgkin lymphoma (HL) has been declining. The aim of the study was to compare HIV-infected patients with NHL and HL with respect to antiretroviral therapy (ART) exposure at the time of lymphoma diagnosis. HIV-infected patients with NHL and HL included in a prospective multicentre cohort study since January 2005 were compared with respect to ART exposure and viral load at the time of lymphoma diagnosis. As of 31 December 2012, data for 329 patients with NHL and 86 patients with HL from 31 participating centres were available. Patients with HL were more likely to be on ART (73.5% vs. 39.1%, respectively; P 12 months and a CD4 cell count of > 200 cells/μL. Of note, 45.8% of all patients with NHL were not currently on ART and had a CD4 count of < 350 cells/μL. This prospective cohort study shows that HL was as common as NHL in patients with sustained viral suppression and limited immune deficiency. In contrast to NHL, the majority of patients with HL were on effective ART, suggesting that ART provides insufficient protection from developing HL. The high proportion of untreated patients with NHL suggests missed opportunities for earlier initiation of ART. © 2014 British HIV Association.
Full Text Available Background: The aimed of almost all of patient came for orthodontics treatment, were to recover face esthetic or their profile. The facial profile not only determined by the hard tissue, but will also be influenced by the soft tissue such as nose, lip, and chin. Tweed has done face analysis with cephalometric by using three angles which are FMA, FMIA, and IMPA. There are many facial profile analysis that usually use in lateral cephalometric one of them is Ricketts analysis that draw the line from pogonion to the tip of nose. The biggest tribe in Indonesia is Javanese, the Javanese have a specific characteristic. Javanese people do not have a long nose and the chin not really uppermost, thick lip, convex profile and female’s profile more convex than male. Purpose: The study was aimed to examine the relation between Tweed triangle, upper lip and lower lip to esthetic line according to Ricketts. Methods: The facial profile pictures of subjects which were taken base on sample criteria changed into silhouette black and white. The photo selected by orthodontist and lay persons. Then the lateral cephalometric radiograph was taken and measured the angle of Tweed triangle and the lip position to esthetic line. Results: The FMA were 28.830, FMIA were 56.740 and IMPA were 94.430. The upper lip distance among males were closer to the esthetic line than female. The lower lip of males located in front of esthetic line and female lower lip located rare of esthetic line. Conclusion: There was corelation between FMA and FMIA with lower lip. There was no corelation between IMPA towards upper lip and also lower lip.Latar belakang: Tujuan dari hampir seluruh pasien yang datang untuk perawatan ortodonti adalah untuk memperbaiki estetis wajah atau profilnya.

Background and Aims For HIV-positive individuals who use illicit opioids, engagement in methadone maintenance therapy (MMT) can contribute to improved HIV treatment outcomes. However, to our knowledge, the role of methadone dosing in adherence to antiretroviral therapy (ART) has not yet been investigated. We sought to examine the relationship between methadone dose and ART adherence among a cohort of persons who use illicit opioids. Design and Setting We used data from the ACCESS study, an ongoing prospective observational cohort of HIV-positive persons who use illicit drugs in Vancouver, Canada, confidentially linked to comprehensive HIV treatment data in a setting of universal no-cost medical care including medications. We evaluated the longitudinal relationship between methadone dose and the likelihood of ≥ 95% adherence to ART among ART-exposed participants during periods of engagement in MMT. Participants 297 ART-exposed individuals on MMT were recruited between December 2005 and May 2013 and followed for a median of 42.1 months. Measurements We measured methadone dose at ≥ 100 vs methadone maintenance therapy, those receiving higher doses of methadone (≥ 100 mg/day) are more likely to achieve ≥ 95% adherence to antiretroviral therapy than those receiving lower doses.

The positive relationships between biodiversity and aboveground biomass are important for biodiversity conservation and greater ecosystem functioning and services that humans depend on. However, the interaction effects of plant coverage and biodiversity on aboveground biomass across plant growth forms (shrubs, forbs and grasses) in natural rangelands are poorly studied. Here, we hypothesized that, while accounting for environmental factors and disturbance intensities, the positive relationships between plant coverage, biodiversity, and aboveground biomass are ubiquitous across plant growth forms in natural rangelands. We applied structural equation models (SEMs) using data from 735 quadrats across 35 study sites in semi-steppe rangelands in Iran. The combination of plant coverage and species richness rather than Shannon's diversity or species diversity (a latent variable of species richness and evenness) substantially enhance aboveground biomass across plant growth forms. In all selected SEMs, plant coverage had a strong positive direct effect on aboveground biomass (β = 0.72 for shrubs, 0.84 for forbs and 0.80 for grasses), followed by a positive effect of species richness (β = 0.26 for shrubs, 0.05 for forbs and 0.09 for grasses), and topographic factors. Disturbance intensity had a negative effect on plant coverage, whereas it had a variable effect on species richness across plant growth forms. Plant coverage had a strong positive total effect on aboveground biomass (β = 0.84 for shrubs, 0.88 for forbs, and 0.85 for grasses), followed by a positive effect of species richness, and a negative effect of disturbance intensity across plant growth forms. Our results shed light on the management of rangelands that is high plant coverage can significantly improve species richness and aboveground biomass across plant growth forms. We also found that high disturbance intensity due to heavy grazing has a strong negative effect on plant coverage rather than species

Psoriasis can greatly impact patients' lives by influencing clothing worn as well as by impairing sexual functioning. Secukinumab, a human monoclonal antibody selectively neutralizing interleukin-17A, has demonstrated good efficacy and safety in the treatment of moderate-to-severe psoriasis and psoriatic arthritis with a rapid onset of action and sustained response. This analysis using the CLEAR study, a phase 3b double-blind study comparing the efficacy and safety of secukinumab vs. ustekinumab in adults with moderate-to-severe plaque psoriasis, evaluated the treatment effects on patient's daily activities and personal relationships. Impact on daily activities (interference with home/shopping/garden, and influence on clothes worn) and impact on personal relationships (problems with partner/others, and sexual difficulties) as well as their corresponding subscales were selected from the Dermatology Life Quality Index scale and evaluated for patients treated with secukinumab vs. ustekinumab from the CLEAR study. Treatment differences in mean scores and proportions of responders (score = 0, indicating no impact) were evaluated through 52 weeks. Time to response was evaluated through Week 16. Significant differences between secukinumab and ustekinumab were observed for daily activities and personal relationships at Week 16 and sustained through Week 52 (Week 52 response rates for daily activities: 82.9% vs. 73.5%, including interference with home/shopping/garden: 88.5% vs. 78.2%, and influence on clothes worn: 85.6% vs. 74.4%; personal relationships: 86.1% vs. 73.7%, including problems with partner/others: 86.6% vs. 74.8%, and sexual difficulties: 88.5% vs. 74.3%; all P personal relationships (both P < 0.05). Secukinumab treatment helps patients with moderate-to-severe plaque psoriasis have a more normal life faster when compared to ustekinumab, by providing greater and sustained improvement in clothing choice and sexual functioning. © 2017 European Academy of

Antioxidative peptides have attracted increasing attention from researchers because of their antioxidant properties as natural materials in functional food and for applications in medicine. However, the relationship between structure and activity (SAR) remains unclear, especially in antioxidative peptides in free radical systems. Antioxidative peptides with different lengths were obtained from the literature, measured using different methods, and were organized into three databases, namely, Trolox-equivalent antioxidant capacity (TEAC), oxygen radical absorption capacity (ORAC), and superoxide radical (SOR). After the peptides were processed using the two-terminal position numbering method, quantitative SAR modeling was performed on antioxidative peptides in the three databases. The vectors of hydrophobic, steric, and electronic properties (VHSE) and the divided physicochemical property scores descriptors (DPPS) were selected from 17 physicochemical descriptors to express electronic, hydrophobic, and steric properties (or hydrogen bonding) of the three (or four) external amino acids in the N-terminal and C-terminal positions. Models were estimated using partial least squares regression and validated through full cross-validation and external validation (R(2)>0.7, Q(2)>0.5 for TEAC; R(2)>0.9, Q(2)>0.5 for ORAC and SOR). The results found a relationship between the physicochemical properties of the C-terminal and N-terminal regions and antioxidant potency. The properties of amino acids at C-terminal regions were more important than those at the N-terminal regions for predicting antioxidant activity. The properties of amino acids at C(2)>C(1) for TEAC, C(3)>C(4)>C(1) for ORAC, and C(4)>C(1)>N(1) for SOR were highly correlated with antioxidant activity. Although electronic property most significantly contributed to antioxidant activity in the three free radical systems, it had complex effects at each position. Bulky hydrophobic amino acids at the C-terminal were

A system and method utilizes distance-measuring equipment including a laser sensor for controlling the collection instrument-to-surface distance during a sample collection process for use, for example, with mass spectrometric detection. The laser sensor is arranged in a fixed positional relationship with the collection instrument, and a signal is generated by way of the laser sensor which corresponds to the actual distance between the laser sensor and the surface. The actual distance between the laser sensor and the surface is compared to a target distance between the laser sensor and the surface when the collection instrument is arranged at a desired distance from the surface for sample collecting purposes, and adjustments are made, if necessary, so that the actual distance approaches the target distance.

Scale-up of triple-drug antiretroviral therapy (ART) in Africa has transformed the context of childbearing for HIV-positive women and may impact pregnancy incidence in HIV programs. Using observational data from 47,313 HIV-positive women enrolled at 26 HIV clinics in Kenya and Uganda between 2001 and 2009, we calculated the crude cumulative incidence of pregnancy for the pre-ART and on-ART periods. The causal effect of ART use on incident pregnancy was assessed using inverse probability weighted marginal structural models, and the relationship was further explored in multivariable Cox models. Crude cumulative pregnancy incidence at 1 year after enrollment/ART initiation was 4.0% and 3.9% during the pre-ART and on-ART periods, respectively. In marginal structural models, ART use was not significantly associated with incident pregnancy [hazard ratio = 1.06; 95% confidence interval (CI): 0.99 to 1.12]. Similarly, in Cox models, there was no significant relationship between ART use and incident pregnancy (cause-specific hazard ratio: 0.98; 95% CI: 0.91 to 1.05), but effect modification was observed. Specifically, women who were pregnant at enrollment and on ART had an increased risk of incident pregnancy compared to those not pregnant at enrollment and not on ART (cause-specific hazard ratio: 1.11; 95% CI: 1.01 to 1.23). In this large cohort, ART initiation was not associated with incident pregnancy in the general population of women enrolling in HIV care but rather only among those pregnant at enrollment. This finding further highlights the importance of scaling up access to lifelong treatment for pregnant women.

Objective: To explore the relationship between HBeAg in HBsAg positive mothers and CD(4)(+)CD(25)(+)Foxp3(+)regulatory T cells (Treg) in newborns, as well as how they would influence the increasing risk on HBV intrauterine transmission. Methods: We collected information on general demographic characteristics and delivery on 270 HBsAg positive mothers and their newborns from the Third People's Hospital of Taiyuan. Fluorescence quantitative polymerase chain reaction (FQ-PCR) and chemiluminescence immunoassay (CLIA) were used to detect HBV DNA and HBV serological markers in peripheral blood from both mothers and neonates. The expression of Treg and other immune cells in peripheral blood of neonates were detected with flow cytometry (FCM). Results: Maternal HBeAg positive rates were associated with an increased risk of intrauterine transmission (OR=4.08, 95%CI: 1.89-8.82). Rates of Treg in newborns born to HBsAg-positive mothers were higher than that of the negative group (Z=2.29, P=0.022). Each pair of the subjects was assigned to five different groups according to the HBeAg titers of mothers. Frequencies of both Treg and HBeAg in newborns and HBV DNA in mothers between the above said 5 groups showed similar trends of changing patterns and the differences between groups were statistically significant(χ(2)=18.73, Pmother's HBeAg titers were positively related to the percentage of Treg in their newborns (r(s)=0.19, P=0.039). In addition, the frequencies of Treg were negatively correlated with pDC and CD(4)(+) T cell in their newborns (r(s)=-0.21, P=0.017; r(s)=-0.23, P=0.009). Conclusion: HBeAg from HBsAg positive mothers might have inhibited the function of neonatal DC cells and T cells to reduce the immune response to HBV by up-regulating the proportion of Treg and finally increased the risk of HBV intrauterine transmission.
Full Text Available Oxidative stress is considered to be a critical factor in diabetes-induced endothelial progenitor cell (EPC dysfunction, although the underlying mechanisms are not fully understood. In this study, we investigated the role of high mobility group box-1 (HMGB-1 in diabetes-induced oxidative stress. HMGB-1 was upregulated in both serum and bone marrow-derived monocytes from diabetic mice compared with control mice. In vitro, advanced glycation end productions (AGEs induced, expression of HMGB-1 in EPCs and in cell culture supernatants in a dose-dependent manner. However, inhibition of oxidative stress with N-acetylcysteine (NAC partially inhibited the induction of HMGB-1 induced by AGEs. Furthermore, p66shc expression in EPCs induced by AGEs was abrogated by incubation with glycyrrhizin (Gly, while increased superoxide dismutase (SOD activity in cell culture supernatants was observed in the Gly treated group. Thus, HMGB-1 may play an important role in diabetes-induced oxidative stress in EPCs via a positive feedback loop involving the AGE/reactive oxygen species/HMGB-1 pathway.

Pregnancy is common among adolescents in South Africa, yet the social experiences of adolescents during the pregnancy and postpartum period remain understudied in this context. We aimed to explore how adolescent women's discovery and disclosure of both their pregnancy and HIV status affected their relationships with family members and sexual partners, with a particular focus on whether and how support changed throughout this time period. We conducted in-depth semi-structured interviews with 15 HIV-positive and HIV-negative adolescent women who were either pregnant or had delivered in the last 18 months from one urban clinic in Umlazi, South Africa. Interviews were audiotaped, transcribed, translated, and coded for analysis. Young women described stress and instability in their relationships with family and partners during pregnancy and the postpartum period, though prior to and during HIV-status disclosure women generally experienced less stress than in disclosing their pregnancy to family members and partners. After a destabilizing period immediately following pregnancy disclosure, families became and remained the primary source of material and emotional support for the young women. Women discussed heightened closeness with their partners during pregnancy, but few women had close relationships with their partners postpartum. Support experiences did not differ by HIV status. Programs should be aware of the relative importance of pregnancy-related concerns over HIV-related concerns in this population of young women. Engaging family members is critical in ensuring social support for this population of young pregnant women, and in encouraging timely initiation of antenatal care.

Brazil is one of the largest agricultural producers in the world. However, its agrarian composition is based on two markedly different production models, particularly in relation to sustainability: a peasant family agriculture, which plays an important role in food production for domestic consumption and advocates agro-ecological practises; and agribusiness, the politically and economically hegemonic model that produces commodities for export based on monoculture and intensive use of pesticides. Therefore, in order to create the means to develop peasant lands, social movements and peasants have engaged themselves politically and defended an education model grounded in sustainable practises of production and social organisation. Taking this into account, the main purpose of this paper is to analyse and assess the Brazilian experience of integration between education and sustainability, in the National Education Program in Agrarian Reform (PRONERA). To accomplish this aim, a survey with a semi-structured questionnaire was carried out among teachers, students, monitors, and coordinators of the course offered by PRONERA. The surveys showed that the courses are promoting the concepts of sustainability among peasants. However, many adjustments need to be taken into consideration during the planning process for the next courses offered by PRONERA. Copyright © 2015 Elsevier Ltd. All rights reserved.

Female cross-border migrants experience elevated risks for HIV, and migrants in South Africa may face additional risks due to the country's underlying HIV prevalence. These risks may be mitigated by the receipt of social support. A behavioral risk-factor survey was administered using respondent-driven sampling. Multivariable regression models assessed the relationships between social support and two HIV outcomes: HIV serostatus and perceived HIV status. Low social support was not significantly associated with HIV status (aOR = 1.03, 95 % CI 0.43-2.46), but was significantly related to a perception of being HIV positive (aPR = 1.36, 95 % CI 1.04-1.78). Age, marital status, and education level were significantly associated with HIV serostatus. Illegal border-crossing, length of time in South Africa, anal sex, and transactional sex were significantly associated with aperception of being HIV positive. Future research should investigate how HIV risks and the receipt of social support change throughout the migration process.
Myeloperoxidase-Related Chlorination Activity Is Positively Associated with Circulating Ceruloplasmin in Chronic Heart Failure Patients: Relationship with Neurohormonal, Inflammatory, and Nutritional Parameters
Full Text Available Rationale. Heart failure (HF is accompanied by the development of an imbalance between oxygen- and nitric oxide-derived free radical production leading to protein nitration. Both chlorinating and peroxidase cycle of Myeloperoxidase (MPO contribute to oxidative and nitrosative stress and are involved in tyrosine nitration of protein. Ceruloplasmin (Cp has antioxidant function through its ferroxidase I (FeOxI activity and has recently been proposed as a physiological defense mechanism against MPO inappropriate actions. Objective. We investigated the relationship between plasma MPO-related chlorinating activity, Cp and FeOxI, and nitrosative stress, inflammatory, neurohormonal, and nutritional biomarkers in HF patients. Methods and Results. In chronic HF patients (n=81, 76 ± 9 years, NYHA Class II (26; Class III (29; Class IV (26 and age-matched controls (n=17, 75 ± 11 years, CTR, plasma MPO chlorinating activity, Cp, FeOxI, nitrated protein, free Malondialdehyde, BNP, norepinephrine, hsCRP, albumin, and prealbumin were measured. Plasma MPO chlorinating activity, Cp, BNP, norepinephrine, and hsCRP were increased in HF versus CTR. FeOxI, albumin, and prealbumin were decreased in HF. MPO-related chlorinating activity was positively related to Cp (r= 0.363, P<0.001, nitrated protein, hsCRP, and BNP and inversely to albumin. Conclusions. Plasma MPO chlorinated activity is increased in elderly chronic HF patients and positively associated with Cp, inflammatory, neurohormonal, and nitrosative parameters suggesting a role in HF progression.

Although nursing has a long history of service to the global community, the profession lacks a theoretical and empirical base for nurses to frame their global practice. A study using grounded theory methodology to investigate partnership and sustainability for global health led to the development of a conceptual model. Interviews were conducted with 13 global health nurse experts. Themes from the interviews were: components for engagement, mutual goal setting, cultural bridging, collaboration, capacity building, leadership, partnership, ownership, and sustainability. Next, the identified themes were reviewed in the literature in order to evaluate their conceptual relationships. Finally, careful comparison of the interview transcripts and the supporting literature led to the Conceptual Framework for Partnership and Sustainability in Global Health Nursing. The model posits that engagement and partnership must precede any planning and intervention in order to create sustainable interventions. This conceptual framework will offer nurses important guidance for global health nursing practice. © 2010 Wiley Periodicals, Inc.

To elucidate the relationship between the anatomic position of the inferior alveolar nerve (IAN) at the mandibular second molar and the occurrence of neurosensory disturbances of the IAN after sagittal split ramus osteotomy (SSRO) in patients with mandibular prognathism. Also, the present study evaluated the difference in anatomic position of the IAN between patients with and without mandibular prognathism. Computed tomography images were taken of 28 patients with mandibular prognathism and 30 without prognathism. On these scans, the IANs from the mandibular second molar region to the mandibular foramen in the mandibular ramus were identified. The present study was designed as a cross-sectional study. The distance from the buccal aspect of the IAN canal to the outer buccal cortical margin of the mandible in the mandibular second molar regions was measured on the computed tomography images. Also, the linear distance between the superior aspect of the IAN canal and the alveolar crest in these regions was calculated. In addition, we investigated the presence or absence of contact between the IAN canal and the inner buccal cortical margin of the mandible from the mandibular second molar to the mandibular foramen in the mandibular ramus. Next, we examined whether neurosensory disturbances occurring after SSRO were related to the position of the IAN at the mandibular second molar. A significant difference was found in the occurrence of neurosensory disturbances of the IAN after SSRO between men and women (χ(2) test, P mandibular second molar region, a significant difference was found between groups with and without neurosensory disturbances (Student's t test, P position of the IAN canal at the mandibular second molar are significantly related to the occurrence of neurosensory disturbances of the IAN after SSRO. Therefore, surgeons should clearly inform patients of the increased possibility of neurosensory disturbances after SSRO when the patients are female and are

To: (1) determine the percentage of the population in England that have access to a community pharmacy within 20 min walk; (2) explore any relationship between the walking distance and urbanity; (3) explore any relationship between the walking distance and social deprivation; and (4) explore any interactions between urbanity, social deprivation and community pharmacy access. This area level analysis spatial study used postcodes for all community pharmacies in England. Each postcode was assigned to a population lookup table and lower super output area (LSOA). The LSOA was then matched to urbanity (urban, town and fringe or village, hamlet and isolated dwellings) and deprivation decile (using the Index of Multiple Deprivation score). Access to a community pharmacy within 20 min walk. Overall, 89.2% of the population is estimated to have access to a community pharmacy within 20 min walk. For urban areas, that is 98.3% of the population, for town and fringe, 79.9% of the population, while for rural areas, 18.9% of the population. For areas of lowest deprivation (deprivation decile 1) 90.2% of the population have access to a community pharmacy within 20 min walk, compared to 99.8% in areas of highest deprivation (deprivation decile 10), a percentage difference of 9.6% (8.2, 10.9). Our study shows that the majority of the population can access a community pharmacy within 20 min walk and crucially, access is greater in areas of highest deprivation--a positive pharmacy care law. More research is needed to explore the perceptions and experiences of people--from various levels of deprivation--around the accessibility of community pharmacy services.

The position of the mental foramen and the anterior loop length of the inferior alveolar nerve serve as important anatomical landmarks for surgical procedures in the anterior mandibular region. The purpose of this study was to determine the relationship between the anterior loop of the inferior alveolar nerve and the mental foramen by combining cone beam computed tomography and Mimics, a software used to construct 3-dimensional (3D) interactive models of anatomical structures. Cone beam computed tomography images from a total of 60 patients were obtained and studied using GALAXY viewer or were imported into Mimics. The anterior loop of the inferior alveolar nerve was reconstructed 3-dimensionally, and then relevant parameters were measured. The parameters were measured, and their values include mean (SD) anterior loop length, 1.16 (1.78) mm; anterior loop angle, 19.13 (26.89) degrees; inferior alveolar canal diameter, 3.01 (0.67) mm; height of the inferior alveolar canal, 10.32 (1.56) mm; 2-dimensional mental foramen diameter, 2.97 (0.61) mm; 3D mental foramen diameter, 2.95 (0.59) mm; 2-dimensional vertical height of the mental foramen, 14.67 (1.67) mm; and 3D vertical height of the mental foramen, 14.61 (1.69) mm. The mental foramen was located apically between the first and second premolars in 51.67% and below the second premolar in 40.83% of the cases. A relationship was observed between the location of the mental foramen and the presence of the anterior loop of the inferior alveolar nerve. We highlight the effectiveness of cone beam computed tomography and 3D reconstruction in the identification of important anatomical structures relevant for preoperative assessment for surgical procedures in the anterior region of the mandible.
Full Text Available Previous observational studies have reported associations between prostate cancer and alpha-linolenic acid (ALA. However, few investigations have been able to study this relationship prospectively and in well-controlled settings. Moreover, no studies have determined whether single nucleotide polymorphisms (SNPs that influence ALA metabolism are associated with this common cancer. The purpose of this study was to explore associations between prostatic levels of ALA, SNPs and prostate cancer-specific biomarkers in samples collected from a previous randomized clinical trial conducted using a presurgical model and which tested the effects of flaxseed supplementation, a rich source of ALA, prior to prostatectomy (n = 134. Serum prostate-specific antigen (PSA was determined and immunohistochemistry was used to assess tumor proliferation rate (Ki67. Prostatic ALA was determined with gas chromatography. Seven previously identified SNPs associated with delta-6 desaturase activity (rs99780, rs174537, rs174545, rs174572, rs498793, rs3834458 and rs968567 were tested for associations with prostatic ALA, PSA and Ki67. Despite consuming seven times more ALA per day, men in the flaxseed arm had similar amounts of prostatic ALA relative to men not consuming flaxseed. In unadjusted analysis, there were significant positive associations between prostatic ALA and PSA (ρ = 0.191, p = 0.028 and Ki67 (ρ = 0.186, p = 0.037. After adjusting for covariates (flaxseed, age, race, BMI and statin-use the association between ALA and PSA remained (p = 0.004 but was slightly attenuated for Ki67 (p = 0.051. We did not observe associations between any of the SNPs studied and prostatic ALA; however, in models for PSA there was a significant interaction between rs498793 and ALA and for Ki67 there were significant interactions with ALA and rs99780 and rs174545. Independent and inverse associations were observed between rs174572 and Ki67. This study

Full Text Available Tourism is an important development tool and it is considered the second largest contributor to the Malaysian economy. Even though the visitors are satisfied by the prevailing facilities, a few shortcomings need to be addressed on sustainable tourism such as the lack of knowledge on sustainable tourism in different sectors, and the neglected local communities in making decisions on sustainability. The aim of this study is to realize the relationship between three factors namely economy, environmental impacts of tourism, and community satisfaction and perceptions on tourism development in Melaka, a UNESCO World Heritage site in Malaysia. In order to observe this relationship, 735 tourists were interviewed to get the tourists’ responses. Here, the concepts on sustainable tourism development include the conservation of the environment, mitigation of pollution from tourism development, and support of local economies. Additionally, sustainable tourism is aimed at generating local employment for the community. Data from the interviews have been analysed using descriptive and simple statistical tools. It is found that the variables are suitable in this study due to the high Cronbach’s Alpha values. The study found that there are positive significant influences between the three dimensions and their perceptions on sustainability and tourism development.

Full Text Available Tourism is perceived as an appropriate solution for pursuing sustainable economic growth due to its main characteristics. In the context of sustainable tourism, gamification can act as an interface between tourists (clients, organisations (companies, NGOs, public institutions and community, an interface built in a responsible and ethical way. The main objective of this study is to identify gamification techniques and applications used by organisations in the hospitality and tourism industry to improve their sustainable activities. The first part of the paper examines the relationship between gamification and sustainability, highlighting the links between these two concepts. The second part identifies success stories of gamification applied in hospitality and tourism and reviews gamification benefits by analysing the relationship between tourism organisations and three main tourism stakeholders: tourists, tourism employees and local community. The analysis is made in connection with the main pillars of sustainability: economic, social and environmental. This study is positioning the role of gamification in the tourism and hospitality industry and further, into the larger context of sustainable development.
Full Text Available The main objective of this paper is to present the factors with influence on the sustainable university management and the relationships between them. In the scientific approach we begin from a graphical model, according to which the extracurricular activities together with internal environmental factors influence students’ involvement in such activities, the university attractiveness, their academic performance and their integration into the socially-economic and natural environment (components related with sustainable development. The model emphasizes that individual performances, related to students’ participation in extracurricular activities, have a positive influence on the sustainability of university management. The results of the study have shown that the university sustainability may be influenced by a number of factors, such as students’ performance, students’ involvement in extracurricular activities or university’s attractiveness and can in turn influence implicitly also the sustainability of university management. The originality of the paper consists in the relationships study using the modeling method in general and informatics tools of modeling in particular, as well as through graphical visualization of some influences, on the sustainability university management.

Families are referred to pediatric palliative care (PPC) programs when a child is diagnosed with a medical condition associated with less than a full life expectancy. When a child dies, PPC programs typically offer a range of bereavement interventions to these families, often focusing on parents. Currently, it is unclear which factors increase the likelihood that bereaved siblings will experience negative outcomes, limiting the development of empirically supported interventions that can be delivered in PPC programs. The present study explored the relationship between parents' and surviving sibling's mental health symptoms (i.e., post-traumatic stress disorder [PTSD], prolonged grief disorder (PGD), and depression symptoms) after a child's death. Additionally, the extent to which parent functioning indirectly impacted sibling functioning through parenting behaviors (i.e., positive parenting and parent involvement) was also examined, with a specific focus on differences based on parent gender. Sixty bereaved parents and siblings (aged 8-18) who enrolled in a PPC program from 2008 to 2013 completed measures of PTSD, PGD, and depression related to the loss of a child/sibling. Siblings also completed a measure of general parenting behaviors. Maternal, but not paternal, symptoms of PTSD and PGD were directly associated with sibling outcomes. Paternal symptoms were associated with sibling symptoms indirectly, through parenting behaviors (i.e., via decreasing positive parenting). These results underscore the importance of examining both maternal and paternal influences after the death of a child, demonstrate differential impact of maternal vs. paternal symptoms on siblings, and stress the importance of addressing postloss symptoms from a family systems perspective.

The family context plays a critical role in the health of the child. This was the first study to examine the usefulness of the General Functioning subscale of the Family Assessment Device (FAD-GF) in assessing family functioning and its relationship to internalizing symptoms in school-aged children aged between 9 and 11 years of age. Eight hundred and forty-seven year 4 and 5 students from 13 schools (607 intervention students, and 240 control students) participated in the Aussie Optimism Positive Thinking Skills Program (AO-PTS) - a universal school-based program targeting internalizing symptoms. Students rated how 'healthy' they perceived their family to be at pre-test and at 6-months follow-up. Although some aspects of validity and reliability could be improved, results indicated that perceptions of family functioning at pre-test were predictive of internalizing symptoms at the 6-months follow-up. The FAD-GF therefore showed promise as a potential measure of family functioning for children as young as 9 years old. Regardless of children's pre-test levels of perceived family functioning, no intervention effects were found on the anxiety and depression scales; this finding suggests that child perceptions of family functioning may act as a general protective factor against internalizing symptomology.

The incidence of heterosexual HIV transmission continues to increase in the USA. However, little is known about factors that influence high-risk behavior among men who do not have sex with men (MDSM). This study examines the association of childhood sexual abuse and high-risk behaviors among MDSM. The Coping with HIV/AIDS in the Southeast (CHASE) study included 611 HIV-positive individuals in the Southeastern US Bivariate statistics were used to examine the influence of childhood sexual abuse among MDSM, men who have sex with men (MSM), and women. Study findings indicated that among MDSM with HIV, childhood sexual abuse predicted a higher number of sexual partners, alcohol and drug use problems, depression, post-traumatic stress disorder (PTSD), and less trust in medical providers. Similar statistically significant relationships between childhood sexual abuse and negative outcomes were not found for MSM and women with the exception of childhood sexual abuse predicting PTSD and alcohol use in women. Study findings indicate a need for more in-depth research to examine the role of childhood sexual abuse in shaping adult risk behaviors among MDSM as well as a need to assess for and address childhood sexual abuse in this population.

To explore staff perceptions about sustainability, commitment to change, participation in change process, and information received about the change project within the Veterans Administration Primary Care and Mental Health Integration (PC-MHI) initiative and to examine differences from the Veterans Health Administration Mental Health Systems Redesign (MHSR) initiative. Surveys of change team members involved in the Veterans Affairs PC-MHI and MHSR initiatives. One-way analysis of variance examined the relationship between commitment, participation and information, and sustainability. Differences in PC-MHI sustainability were explored by location and job classification. Staff sustainability perceptions were compared with MHSR results. Sustainability differed by staff discipline. Difference between MHSR and PC-MHI existed by job function and perceptions about the change benefits. Participation in the change process and information received about the change process were positively correlated with sustainability. Staff commitment to change was positively associated with staff perceptions about the benefits of change and staff attitudes toward change. Sustainability is an important part of organizational change efforts. Change complexity seems to influence perception about sustainability and impacts staff perceptions about the benefits of change. These perceptions seem to be driven by the information received and opportunities to participate in the change process. Further research is needed to understand how information and participation influence sustainability and affect employee commitment to change.

This paper investigates whether environmental management is an economically sustainable business. While firms invest in green production and green supply chain activities with the primary purpose of reducing their environmental impact, the reciprocal relationships with economic performance need to be clarified. Would firms and suppliers adjust their environmental strategies if the higher economic value that environmental management generates is reinvested in greening actions? We found out that environmental management positively influences economic performance as second order (long term) target, to be reached conditioned by higher environmental performance; in addition, firms can increase their performance if they reinvest the higher economic value gained through environmental management in green practices: While investing in environmental management programs is a short term strategy, economic rewards can be obtained only with some delays. Consequently, environmental management is an economically sustainable business only for patient firms. In the evaluation of these reciprocal relationships, we discovered that green supply chain initiatives are more effective and more economically sustainable than internal actions.

Although studies support the clinical importance of the fibres from the horns of lateral meniscus (LM), few studies have investigated the detailed anatomy. This anatomic study was conducted to analyse the structural details of LM with special reference to (1) the attachment area of the fibres from the anterior and posterior horns and (2) the positional relationship between these fibres and the anterior cruciate ligament (ACL). A total of 24 cadaveric knees were used in the macroscopic investigation, and six knees were used in the histological investigation. Micro-computed tomography analysis was also performed to assess the anatomy of the posteriormost fibre from the posterior horn of LM. Based on the macroscopic investigations, the outer fibres from the anterior horn of LM extended to ACL and seemed to intermingle with ACL fibres. However, the histological investigations showed a distinct border between the fibres and ACL. The inner fibres from the anterior horn of LM attached to the lateral intercondylar tubercle serving as a lateral margin of ACL attachment. Fibres from the posterior horn of LM were separated into anterolateral and posteromedial crura which attached to the posterior aspect of the lateral and medial intercondylar tubercles, respectively. These two crura formed the posterior margin of the ACL attachment, except for the central part of ACL. The outer fibres from the anterior horn of LM adjoined ACL. The inner fibres from the anterior horn of LM and two crura from the posterior horn of LM formed the border of the attachment area of ACL. The distinctive fibre anatomy from LM could provide a surgical landmark during arthroscopic surgery.

IgE-mediated mechanisms are important in immediate hypersensitive reactions (IHR) to buckwheat. However, a part of subjects with high IgE for buckwheat show no IHR to buckwheat ingestion. Inspite of cross-allergenicity between buckwheat and rice, rice ingestion rarely induces IHR even in subjects with high IgE for rice unlike buckwheat-induced IHR. We speculated that there were some relationships between the presence of IHR to buckwheat and recognition of cross-allergenic determinants on buckwheat components with rice components. We examined IgE-RAST for rice in 58 subjects with positive IgE-RAST for buckwheat. IgE-RAST for Dermatophagoides pteronyssinus (Dp), egg white and cow's milk as unrelated antigens with rice were also assessed for a comparison. Subjects (n = 33) without IHR to buckwheat showed higher IgE-RAST values for rice than those (n = 25) with IHR, whereas there were no differences in IgE-RAST values for Dp, egg white and cow's milk between two groups with and without IHR. IgE-RAST values for buckwheat showed significant close correlations to those for rice in subjects without IHR to buckwheat but not in those with IHR. There were no significant correlations between IgE-RAST values for buckwheat and for Dp, egg white or cow's milk in both groups with and without IHR. These results suggested that the IgE from subjects without IHR to buckwheat recognized cross-allergenic determinants with rice on the buckwheat components.

HIV prevalence and incidence in South Africa remain high, making HIV a part of everyday life. Community narratives on HIV treatment and prevention are important and influence official and unofficial health messaging and community perceptions and understandings of HIV. We explore how contributors and the columnist of an agony aunt column position HIV relative to choices made about love, partnership, and sex over three years. We analysed all columns of an agony aunt series (Antie Mona) published between December 2012 and November 2015. The column is published in a South African, Afrikaans-language newspaper "Son", prioritising sensationalist news items. Trends were identified through narrative analysis. Data were managed in ATLAS.ti and inductive, iterative coding conducted. It was found that letters to the agony aunt rarely refer to HIV directly (less than 7%). Euphemisms such as diseases of the flesh and the great flu were more commonly used instead of HIV or AIDS. Letters addressed HIV in three ways: direct references to experiences living with HIV; direct questions about HIV prevention; and scenarios where HIV could (from a public health perspective) have been the main concern, but everyday issues took precedence. The majority of letters fell into this latter category where the writers focused on the immediate concerns of good sexual relations, problems related to love and romantic relationships, good moral behaviour of others, and issues of oppressive life conditions rather than on HIV directly. The findings illustrate that informal, public contributions to health information, such as agony aunts, are important narratives that inform popular perspectives on HIV and health. A better appreciation of this context would allow health implementers to ensure that these role players receive updated health messaging to avoid the risk of HIV-related stigma where HIV is used as a moral rod to punish perceived moral transgressions.

Food insecurity may be a barrier to achieving optimal HIV treatment-related outcomes among illicit drug users. This study therefore, aimed to assess the impact of severe food insecurity, or hunger, on plasma HIV RNA suppression among illicit drug users receiving antiretroviral therapy (ART). A cross-sectional Multivariate logistic regression model was used to assess the potential relationship between hunger and plasma HIV RNA suppression. A sample of n = 406 adults was derived from a community-recruited open prospective cohort of HIV-positive illicit drug users, in Vancouver, British Columbia (BC), Canada. A total of 235 (63.7%) reported "being hungry and unable to afford enough food," and 241 (59.4%) had plasma HIV RNA hunger was associated with lower odds of plasma HIV RNA suppression (Odds Ratio = 0.59, 95% confidence interval [CI]: 0.39-0.90, p = 0.015). In multivariate analyses, this association was no longer significant after controlling for socio-demographic, behavioral, and clinical characteristics, including 95% adherence (Adjusted Odds Ratio [AOR] = 0.65, 95% CI: 0.37-1.10, p = 0.105). Multivariate models stratified by 95% adherence found that the direction and magnitude of this association was not significantly altered by the adherence level. Hunger was common among illicit drug users in this setting. Although, there was an association between hunger and lower likelihood of plasma HIV RNA suppression, this did not persist in adjusted analyses. Further research is warranted to understand the social-structural, policy, and physical factors shaping the HIV outcomes of illicit drug users.

Among industrial yeasts used for alcoholic beverage production, most wine and weizen beer yeasts decarboxylate ferulic acid to 4-vinylguaiacol, which has a smoke-like flavor, whereas sake, shochu, top-fermenting, and bottom-fermenting yeast strains lack this ability. However, the factors underlying this difference among industrial yeasts are not clear. We previously confirmed that both PAD1 (phenylacrylic acid decarboxylase gene, YDR538W) and FDC1 (ferulic acid decarboxylase gene, YDR539W) are essential for the decarboxylation of phenylacrylic acids in Saccharomyces cerevisiae. In the present study, single nucleotide polymorphisms (SNPs) of PAD1 and FDC1 in sake, shochu, wine, weizen, top-fermenting, bottom-fermenting, and laboratory yeast strains were examined to clarify the differences in ferulic acid decarboxylation ability between these types of yeast. For PAD1, a nonsense mutation was observed in the gene sequence of standard top-fermenting yeast. Gene sequence analysis of FDC1 revealed that sake, shochu, and standard top-fermenting yeasts contained a nonsense mutation, whereas a frameshift mutation was identified in the FDC1 gene of bottom-fermenting yeast. No nonsense or frameshift mutations were detected in laboratory, wine, or weizen beer yeast strains. When FDC1 was introduced into sake and shochu yeast strains, the transformants exhibited ferulic acid decarboxylation activity. Our findings indicate that a positive relationship exists between SNPs in PAD1 and FDC1 genes and the ferulic acid decarboxylation ability of industrial yeast strains.

To compare two lung injury models (oleic acid [OA] and saline solution washout [SW]) regarding lung morphology, regional inflation, and recruitment during static pressure-volume (PV) curves, and the effects of positive end-expiratory pressure (PEEP) below and above the lower inflection point (Pflex). Fourteen adult pigs underwent OA or SW lung injury. Lung volumes were measured using CT. PV curves were obtained with simultaneous CT scanning at lung apex and base. Fractional inflation and recruitment were compared to data on PEEP above and below Pflex. Severity of lung injury was comparable. At zero PEEP, SW showed an increased amount of edema and poorly aerated lung volume, recruitment during inspiration, and a better oxygenation response with PEEP. Whole-lung PV curves were similar in both models, reflecting changes in alveolar inflation or deflation. On the inspiratory PV limb, recruitment and inflation were on the same line, while there was a substantial difference between deflation and derecruitment on the expiratory limb. PEEP-induced recruitment at lung apex and base was at or above the derecruitment line on the expiratory limb and showed no relationship to the whole-lung expiratory PV curve. The following conclusions were made: (1) OA and SW models are comparable in mechanics but not in lung injury characteristics; (2) neither inspiratory nor expiratory whole-lung PV curves are useful to select PEEP in order to optimize recruitment; and (3) after recruitment, there is no difference in derecruitment between the models at high PEEP, while more collapse occurs at lower PEEP in the basal sections of SW lungs.

The author discusses how the Inter-American Development Bank (IDB) is involved in sustainable energy development. It presently has 50 loans and grants for non conventional renewable energy projects and ten grants for efficiency programs for $600 and $17 million respectively, representing 100 MW of power. The IDB is concerned with how to create a sustainable market for sustainable energy projects. The IDB is trying to work with government, private sector, NGOs, trading allies, credit sources, and regulators to find proper roles for such projects. He discusses how the IDB is working to expand its vision and objectives in renewable energy projects in Central and South America.
THIS IS THE THIRD YEAR BPA has reported on sustainability program accomplishments. The report provides an opportunity to review progress made on sustainability initiatives, evaluate how far we have come and how much we can improve. The program has demonstrated maturation as the concepts of sustainability and resource conservation are communicated and understood. The sustainability program started as an employee-driven “grass roots” effort in 2010. Sustainability is becoming a consideration in how work is performed. The establishment of several policies supporting sustainability efforts proves the positive progress being made. In 2009, BPA became a founder and member of The Climate Registry, a nonprofit collaboration that sets standards to calculate, verify and report greenhouse gas emissions. This year, BPA completed and published our Greenhouse Gas inventory for the years of 2009, 2010 and 2011. The 2012 inventory is currently in the process of third-party verification and scheduled for public release in January 2014. These inventories provide a concrete measure of the progress we are making.

Full Text Available In view of the increasing importance attributed to social responsibility and stakeholder relationship management, more universities have expanded their research topics and their educational programs through the years. High attention is dedicated to the dominant principles and values of internal and external relations, to the innovation processes designed to ensure an approach to sustainable development. However, less attention is dedicated to the sustainability governance orientation and to the development of a strong institutional culture of sustainability, which is a key success factor to improve the quality and the image. This article observes the sustainability governance orientation, through the analysis of the information on the websites of three fair groups of universities in the international Top 500-ARWU (Academic Ranking of World Universities 2015 ranking. The aim is to verify if there is a link between the degree of sustainability culture in the management and the positioning of the universities in the international ranking. In addition, the analysis is compared with self-assessment data carried out by the same universities in terms of performance sustainability through the STARS (Sustainability Tracking, Assessment & Rating System online platform. As principal consideration, we have noted that the best universities in the ranking have a management approach based on a shared vision of sustainability development of their university leaders, who play an essential role affirming and disseminating a sustainability culture. All this opens broader future implications intended to highlight the importance of management sustainability as a quality improvement factor of universities.

Athletes with non-contact anterior cruciate ligament tears have common features in the sagittal plane; namely, the body's center of mass (COM) is located posterior to the base of support, the trunk and knee joints are extended, and the hip angle is flexed. However, the relationships among these variables have not been assessed in field-based movements. This study sought to determine relationships between distances from the COM to the base of support and the trunk, hip, and knee positions in women while playing soccer. Sixty events (29 single-leg landing and 31 single-leg stopping events) were analyzed using two-dimensional video analysis. The relationships among the measurement variables were determined using the Pearson's product-moment correlation coefficient, and stepwise multiple linear regression models were used to explore the relationships between the COM position and the kinematic variables. The distance from the COM to the base of support displayed a moderate negative relationship with the trunk angle (r = -0.623, p angle (r = 0.869, p angles were selected in the best regression model (adjusted r(2) = 0.953, p angle and a decreased limb angle at initial contact are associated with a safer COM position. Neuromuscular training may be useful for controlling the trunk and lower limb positions during dynamic activities.

with their innovativeness and sustainability orientation. To accomplish this, we surveyed 40 TMTs in Iranian small- and medium-sized enterprises (SMEs) at two points in time. We ran a hierarchical multiple regression in order to test the hypotheses of the study. Building a theoretical model based on the Upper......-Echelons framework, we found that the extent to which a TMT is behaviorally integrated is positively and significantly related to TMT innovativeness. Furthermore, our result reveals that a highly behaviorally integrated TMT is more likely to engage in sustainability-oriented actions. Hence, behaviorally integrated...

Full Text Available The developing countries which include Turkey as well, has been adversely effected in terms of sustainability of fiscal policy due to the 2001 crisis and the global crisis in 2008. These developments, which are important for the sustainability of fiscal policy, have increased the interest of researchers in the subject. Therefore, the purpose of this study is to determine whether Turkey's fiscal policy is sustainable for the period 1976-2016. In this study, which examines the sustainability of public debts in Turkey during the period 1976-2016, Bohn (1989 based econometric model with time-varying parameters was estimated by considering the structural changes experienced by the Turkish economy. In this model, the basic relationship is between the dependent variable ration of primary surplus to GDP (fdoranı and the explanatory variable of ration of public debt to GDP kboran. This relationship was empirically positive and statistically significant. This result provides evidence that public debt is sustainable when Turkey's budget policy is assessed for the period covered.

Full Text Available The persistent increase of government debt in Malaysia in the recent years has raised con-cerns as to whether the borrowings have spurred the economy or became a drag on econom-ic growth. The present paper investigates the real effect of government debt on sustainable economic growth in Malaysia using the Autoregressive Distributed Lag approach for the period of 1970-2015. The results show there are positive significant long- and short-run relationships between government debt and sustainable economic growth. There is also a unidirectional causality running from government debt to sustainable economic growth. The findings indicate that Malaysia’s government debt is an important macroeconomic element for sustainability of economic growth in Malaysia. There is no evidence, however, to con-clude that the level of government debt had any adverse impacts on sustainable economic growth.
