A longitudinal study of the stress-buffering effect of social support on postpartum depression: a structural equation modeling approach

ABSTRACT Purpose Postpartum depression (PPD) impacts about one out of eight new mothers. Research has demonstrated that social support is a protector of PPD. Nevertheless, there has been disagreement on how social support influences depression. The objective is to test two theories – main-effect theory and stress-buffering theory of social support on PPD with different definitions of stress and two types of social support. Methods Secondary longitudinal data from the National Data Archive on Child Abuse and Neglect were used. Parenting stress and difficult life circumstances (DLC) measured at six-month postpartum was used to predict the changes in depression from six- to 12-month postpartum; social support at six-month postpartum was conceptualized as a moderator between stress and PPD. Structural Equation Modeling was adopted for the longitudinal analyses. Results DLC and parental distress both showed long-lasting impacts on PPD. Social support was not found to have a direct or indirect effect on PPD. Neither the stress-buffering theory nor the main-effect model was endorsed by this study. Conclusion Interventions that are accessible to new mothers and aim to improve self-efficacy are recommended. Measures with higher psychometric quality should be used in moderation research. More longitudinal studies with shorter lags between measurement occasions are warranted.
Materialism, Awareness of Environmental Consequences and Environmental Philanthropic Behaviour among Potential Donors

We explored the relationship between materialism, awareness of environmental consequences and environmental philanthropic behaviour with a web survey (n=2,079) targeted at potential donors living in Finland. Environmental philanthropic behaviour comprise of donations of money and/or time to environmental charities. The awareness of environmental consequences was divided into egoistic, altruistic and biospheric concerns. Biospheric and egoistic concerns were positively, while materialism was negatively related to environmental philanthropic behaviour. Materialism was related to preference of charismatic species when choosing a target for donation. The results have implications for conservation marketing emphasising the importance of taking the different donor segments into account.
An Active Caring Approach Through Psychological Safety in Construction Projects

Guided by the lean principle of respect for people, it is key to recognize the value of construction workers feeling psychologically safe on site. Psychological safety is proven to be a driver for learning behaviors as it allows workers feel confident about asking questions to get clarity on their work, asking for help, or speaking up when errors occur on site to avoid repeating mistakes. The authors framed the understanding of psychological safety in the context of a construction project and analyzed worker’s perception regarding factors that foster a psychologically safe work environment. In this study, different trades shared their perception about factors that made them feel safe or unsafe while working at the job site. Outcomes highlighted human behavior characteristics such as how the willingness of workers to speak up when they see someone doing something unsafe changed depending on whom they are talking to. Results were analyzed with the project’s leadership team and action items were set in place. Changes implemented included using English and Spanish during weekly meetings and the establishment of an on-site safety committee to strength relations between and amongst different trades as well as discussion with foremen to keep growing psychological safety on site.
EVALUATION OF SHAPED CHARGE PERFORMANCE UNDER ITS VARIABLE FACTORS

In this paper, two main research directions are used to investigate the shaped charge phenomenon and to evaluate its performance. These directions are: (i) analytical and (ii) numerical simulation. The analytical direction is presented by a model consisting of three main phases; these are: (i) jet formation, (ii) jet break-up, and (iii) jet penetration phases. The governing equations that predict the main parameters associated with each phase are presented. These equations are compiled into a computer program; the input data to the model is that of shaped charge model xx. In numerical simulation direction, Autodyn-2D hydrocode is used to simulate the xx shaped charge phenomena and to assess the predictions of the analytical model. The predictions of the analytical model are compared with the corresponding measurements of the tested shaped charges of Ref. [8]; good agreement is generally obtained. In addition, the present results of both research directions are mainly concerned with predicting the effects of some factors of shaped charge model xx on its performance. These factors are: (i) liner thickness, (ii) liner material, (iii) cone angle, (iv) type of explosive and (v) standoff distance. Samples of the predicted results representing the effect of each studied factor on the associated parameters with jet formation and jet penetration phases are presented with relevant analysis and discussions. It was found that the analytical results and the corresponding code predictions were consistent. The obtained results recommended the use of powerful explosive, the decrease of cone angle and the increase of standoff distance, keeping the jet continuity, for increasing the performance of shaped charge model xx.
Effects of Sleep and Age on Prospective Memory Consolidation: A Walk in a Virtual Museum

Prospective memory (PM) refers to our ability to perform actions at the appropriate moment, either when a predetermined event occurs (event-based, EB) or after a predetermined amount of time (time-based, TB). Sleep favors the consolidation of both EB and TB intentions, but whether this benefit is preserved during ageing is still subject to debate. PM was assessed in 28 young and 27 older healthy volunteers using a virtual environment. Participants had to learn and execute intentions after intervals filled with either daytime wakefulness or nighttime sleep. Intentions consisted of four TB, four EB with a strong link between the cue triggering retrieval and the action to be performed (EB-link) and four with no link (EB-nolink). PM was not affected by age, whatever the type of intention and the nature of the retention interval. While sleep reinforced all types of intentions in young participants, this benefit was only observed for TB and EB-link intentions in older adults. Sleep also reinforced the intrinsic PM components in both groups. Thus, when assessed using complex realistic situations, PM is not impaired in ageing. Results are discussed in the light of memory schema theory and the possible impact of cognitive reserve on sleep and memory.
Validity of Actigraphy Compared to Polysomnography for Sleep Assessment in Children With Autism Spectrum Disorder

Actigraphy (ACT) is a non-invasive objective assessment tool for the study of sleep–wake rhythms. It is of particular interest in children with autism spectrum disorder (ASD), as sleep disorders are highly prevalent and have a significant impact on both cognitive and behavioral functions. As polysomnography (PSG), the gold standard for the assessment of sleep, is difficult to perform in children with ASD, ACT has become a tool of choice but has not yet been validated against PSG using state-of-the-art methodology. The main objective of this study was to assess, for the first time, the validity of ACT compared to PSG for the measurement of sleep in children with ASD. During the same night of hospitalization, PSG and ACT were conducted in 26 children (6 girls and 20 boys; mean age 5.4 years ± 1.6) diagnosed with ASD according to DSM-5 criteria and standardized diagnostic scales. Sleep parameters were total sleep time (TST), sleep latency (SL), wake after sleep onset (WASO), and sleep efficiency (SE). To compare PSG and ACT, we conducted sleep parameter agreement analyses including: intraclass correlation coefficient (ICC), Bland-Altman plots, and equivalence tests. The comparison also included an epoch-by-epoch (EBE) agreement analysis to determine sensitivity (ability to detect sleep) and specificity (ability to detect wake). According to equivalence tests, the difference between ACT and PSG measures was clinically acceptable for TST (<30 min, p < 0.01), SL (<15 min, p < 0.001), and SE (10%, p < 0.01), but not for WASO (<15 min, p = 0.13). There was a good agreement between methods for SL (ICC = 0.79) and TST (ICC = 0.85) and a moderate agreement for WASO (ICC = 0.73) and SE (ICC = 0.68). The EBE agreement analysis revealed a high sensitivity (0.94 ± 0.06) and moderate specificity (0.5 ± 0.2). Since sleep disorders are one of the most common comorbidities within the ASD population and are highly prevalent, it is essential to validate objective tools of assessment. To our knowledge, our study is the first to validate ACT compared to PSG, using a state-of-the-art methodology, in children with ASD. The results suggest ACT to be a valid method to evaluate sleep within this population, with a good reliability for most sleep parameters.
Personality Maturation during the Transition to Working Life: Associations with Commitment as A Possible Indicator of Social Investment

The social investment theory (SIT) proposes that personality maturation is triggered by transitions into age–graded roles and psychological commitment to these roles. The present study examines the predictions of SIT by focusing on the transition from student life to working life. We analysed three–wave longitudinal data and compared participants who made the transition into working life (N = 226), participants who combined education with work (N = 387), and participants who did not make the transition at all (N = 287). In contrast to the predictions of SIT, we found no differences in personality maturation between individuals who made the transition into working life and those who did this only partly or not at all. Psychological commitment to work did not explain individual differences in personality maturation for those who made the transition (partly) into working life after controlling for multiple testing. Therefore, the present study did not support the predictions of SIT. © 2019 The Authors European Journal of Personality published by John Wiley & Sons Ltd on behalf of European Association of Personality Psychology
Perceived Organizational Support: A Literature Review

Perceived organizational support (POS), which reflects the organization’s value on employees’ contributions and concern for employee benefits, is an important tool to help organizations establish favourable relationship with employees and motivate employees work hard. This paper aims to make a review of POS concept and the variables related to POS. Research results showed that perceived organizational support emphasizes organizational commitment to employees and is a unilateral relationship. Perceived organizational support is related to employees’ reduced absenteeism, increased job satisfaction, happiness, organizational citizenship behaviour and organizational performance, and also influenced by organizational fairness, working conditions, HR practices, employee characteristics, leadership, management communication. Besides, this paper summarized the measures to improve perceived organizational support, such as supportive or high commitment HR practices, fairness, superior and co-worker supports, employee empowerment. This study helps researchers understand the latest research progress in perceived organizational support.
Ontology based model framework for conceptual design of treatment flow sheets

The primary objective of wastewater treatment is the removal of pollutants to meet given legal effluent standards. To further reduce operators costs additional recovery of resources and energy is desired by industrial and municipal wastewater treatment. Hence the objective in early stage of planning of treatment facilities lies in the identification and evaluation of promising configurations of treatment units. Obviously this early stage of planning may best be supported by software tools to be able to deal with a variety of different treatment configurations. In chemical process engineering various design tools are available that automatically identify feasible process configurations for the purpose to obtain desired products from given educts. In contrast, the adaptation of these design tools for the automatic generation of treatment unit configurations (process chains) to achieve preset effluent standards is hampered by the following three reasons. First, pollutants in wastewater are usually not defined as chemical substances but by compound parameters according to equal properties (e.g. all particulate matter). Consequently the variation of a single compound parameter leads to a change of related parameters (e.g. relation between Chemical Oxygen Demand and Total Suspended Solids). Furthermore, mathematical process models of treatment processes are tailored towards fractions of compound parameters. This hampers the generic representation of these process models which in turn is essential for automatic identification of treatment configurations. Second, treatment technologies for wastewater treatment rely on a variety of chemical, biological, and physical phenomena. Approaches to mathematically describe these phenomena cover a wide range of modeling techniques including stochastic, conceptual or deterministic approaches. Even more the consideration of temporal and spatial resolutions differ. This again hampers a generic representation of process models. Third, the automatic identification of treatment configurations may either be achieved by the use of design rules or by permutation of all possible combinations of units stored within a database of treatment units. The first approach depends on past experience translated into design rules. Hence, no innovative new treatment configurations can be identified. The second approach to identify all possible configurations collapses by extremely high numbers of treatment configurations that cannot be mastered. This is due to the phenomena of combinatorial explosion. It follows therefrom that an appropriate plan-
Comparative Evaluation of Microleakage in Class 2 Cavities Restored with A Nanohybrid Composite Using Three Different Increment Techniques- An in vitro Stereomicroscopic Study

IntroductIon Composites were specifically advocated for use in posterior teeth in the early 1980s and have become increasingly popular in restorative dentistry (1). Despite significant improvements in the composition and performance of composite resins, these materials still exhibit a considerable degree of polymerization shrinkage, which limits their use in direct restoration of composite resin(2). original article Journal of Oral Health Community Dentistry &
Arabic Text Categorization using Machine Learning Approaches

Arabic Text categorization is considered one of the severe problems in classification using machine learning algorithms. Achieving high accuracy in Arabic text categorization depends on the preprocessing techniques used to prepare the data set. Thus, in this paper, an investigation of the impact of the preprocessing methods concerning the performance of three machine learning algorithms, namely, Na¨ive Bayesian, DMNBtext and C4.5 is conducted. Results show that the DMNBtext learning algorithm achieved higher performance compared to other machine learning algorithms in categorizing Arabic text.
Big Five Personality Traits and Life Satisfaction: The Mediating Role of Religiosity

Extensive empirical research conducted up till now has confirmed that personality represents one of the most significant predictors of life satisfaction. Still, no studies to date have empirically tested the path of influence from personality traits to religiosity and the effects of both on life satisfaction/positivity within the same model. In the current study, we aimed to verify whether the relationship between personality and satisfaction/positivity was mediated by religiousness, as it is considered motivational in nature. The sample consisted of 213 participants (72% women) aged between 18 and 75. The average age was approx. 32. We used the following tools: the NEO Five Factor Inventory, the Satisfaction with Life Scale, the Positivity Scale, the Personal Religiousness Scale, and the Intensity of Religious Attitude Scale. Our hypotheses (H1 and H2) found their confirmation to a large degree. In fact, life satisfaction positively correlated with extraversion, agreeableness, and conscientiousness. Moreover, life satisfaction negatively correlated with neuroticism. A similar pattern of results, even slightly stronger, was found in the case of positivity and personality traits. Contrary to our assumptions, neither life satisfaction nor positivity correlated with openness to experience. Extraversion and agreeableness correlated positively with religious attitude, personal religiousness and its four dimensions. Conscientiousness correlated positively only with faith, personal religiousness, and religious attitude. We also found negative and significant correlations between openness and all of the dimensions of personal religiousness. A lack of correlation was found between: (1) neuroticism and all of the dimensions of religiosity; (2) conscientiousness and religious practices, and religious self. Our research offers a contribution to the field by providing evidence that some personality traits predict life satisfaction/positivity because respondents display a personal religiousness/religious attitude.

Can Emotions Capture the Elusive Gain-Loss Framing Effect? A Meta-Analysis

Although recent streams of research have suggested that emotions play a key role in generating framing effects, little is known about the affective dimension of gain and loss framing and its potential impact on persuasion. The current study adopted a meta-analytical approach, synthesizing over 30 years of literature (k = 25, N = 5,772), to investigate this issue. The results indicate that message frame type directs the emotional response elicited in the audience, with gain frames inducing positive emotions (d = .31, p = .02) and loss frames inducing negative emotions (d = .22, p = .001). In turn, the experience of positive emotions enhances the influence of gain frames (b = .18, p = .045), whereas negative emotions augment the effects of loss frames (b = −.70, p = .01). These findings confirm that emotional responses may offer a pathway through which gain- and loss-framed messages exert persuasive influence. The study integrates the results with the emotions-as-frames perspective and proposes several promising avenues for future research.
Blending and becoming: migrant Chinese high-performance coaches’ learning journey in Australia

ABSTRACT Purpose: Despite the recruitment of foreign sport coaches being a relatively long-standing phenomenon, there is limited research examining the experiences of foreign coaches working in globalised high-performance sport contexts. In examining how foreign coaches learn to perform their craft, we draw upon Billett’s [2006. ‘Relational Interdependence Between Social and Individual Agency in Work and Working Life. ’ Mind, Culture, and Activity 13 (1): 53–69. doi:10.1207/s15327884mca1301_5] notion of relational interdependence, which embraces a work-based approach to understanding how migrant coaches learn. Specifically, this lens enables a broad consideration of the interdependent relationship between the foreign coach’s agency and the affordances of the host workplace. Method: A single case (embedded) research design was chosen through the purposeful sampling of a sport organisation. The case focused on the learning of Chinese migrant coaches employed within an Australian high-performance coaching workplace (henceforth referred to as the National Sport Organisation; NSO) and involved data collection from three foreign coaches, four athletes, and four administrators employed by the NSO. Through a multiple data collection method (i.e. 1 year of observation, 20 interviews, 1 focus group, and related document collection), information was collected regarding the coaches’ practices and learning. A theoretical thematic analysis guided the data analytic procedure with the assistance of MindNode software. Results and discussion: Several major themes were identified in relation to Chinese coaches’ learning and practices in the NSO. Overall, Chinese coaches met work requirements through substantial personal learning including aspects related to language (i.e. English), the development of culturally appropriate coaching practices, and enhancement of athletes’ training approach. Conclusion: The findings of this research might be generative for foreign coaches and those responsible for the recruitment, professional learning, and development of such coaches. The notion of relational interdependence was an appropriate theoretical lens for research related to the learning of foreign high-performance sport coaches.
The experiences of educational coaches prior to their first placement: An interpretative phenomenological analysis

Studies of student coaching have shown benefits to both students and coaches, yet little is known about the experiences of coaches as they prepare to coach. This study sought to explore the experiences of six undergraduate trained educational coaches from a UK university prior to their first placement coaching secondary school students. Interpretative Phenomenological Analysis (IPA) was used to collect data, undertake semi-structured interviews, and analyse the data. Three overarching themes emerged from this study: Nervous energy; Sense of responsibility; and Sense of reciprocal benefit. These themes may be helpful in informing training and supporting educational coaches, and may provide insights to inform the development of new theories about the use of coaching with young people.
