Parents’ modelling of play skills in spontaneous interactions may promote autistic children’s play behaviours

BackgroundAutistic children always encounter difficulties in engaging in various play acts. Their parents can play a critical role in their play development. Among the different strategies adopted by parents, modelling, which involves parents demonstrating play acts to their children, can help the latter to develop play skills through observation and imitation. However, very little is known about whether modelling during parent-child spontaneous interactions might influence the production of play acts in autistic children, in comparison to other strategies, such as suggestion, command, and imitation. The present study addressed this issue, and we hypothesized that parents’ modelling of play acts was positively associated with autistic children’s production of play acts. MethodThirty-seven autistic children aged between 73 and 114 months (M = 92.1) from a special school in Hong Kong and their parents were recruited for this study. The parents were instructed to play freely with their children for 20 min. The sessions were videotaped and coded. The children’s play acts were categorized into sensory, relational, functional, and symbolic play, while the parents’ play strategies were categorized into modelling, command, suggestion, and imitation. ResultsAfter controlling for chronological age, autism severity and intelligence, the multiple linear regression showed that the parents’ modelling strategy was significantly and positively associated with the number of their children’s play acts (B =.217, p = .046). ConclusionThe modelling of play acts by the parents is associated with their autistic children’s play acts. It is advisable for parents to demonstrate play activities in daily-life interactions.

The mental health of working women after the COVID-19 pandemic: an assessment of the effect of the rise in sexual harassment during the pandemic on the mental health of Pakistani women using DASS-21.

The mental health of South Asian women has been observed to be in regression lately, with sexual harassment as one of the major factors accounting for mental health deterioration, especially for women who leave their homes frequently for work and study. The COVID-19 pandemic not only augmented the mental health distress of the general female population but the rise in sexual violence against women is being consistently reported around the globe. Based on this background, we adopted a two-pronged strategy to assess whether working women and students aged 18-55 experienced a rise in sexual harassment in the 18 months after lifting the COVID-19 lockdowns. Secondly, using the well-validated psychometric test, DASS-21, we evaluated the psychiatric outcome of this change on the mental health of those women. The study was designed as a quantitative, cross-sectional survey-based research. A total of 303 women participated in this study. Personal interviews through a specifically designed questionnaire and psychometric test DASS-21 were administered to assess the mental health state of working women and female students, aged between 18 and 55 years old. The mean age of the participants was 37 ± 2.8. The study population was further categorized into two main groups of limited and frequent interactions based on varying levels of the frequency of leaving home and interacting with male strangers in their daily routine. Data were analyzed and the correlation between limited/frequent interaction and DASS-21 total scores and sub-scores of depression, anxiety and stress, and other sociodemographic variables were investigated using the Chi-square test, whereas psychosocial predictors of mental distress were evaluated using multiple linear regression analysis after matching limited and frequent interaction groups using a 1:1 propensity score-matched pair method for sociodemographic covariates. Overall, approximately 50% of our study population experienced changes in the behavior of male strangers that could be categorized as harassment in their daily life interactions, whereas 33.66% of participants experienced relatively more sexual harassment post-pandemic than before it. This observation was significantly correlated with the frequency of male interaction (χ2 = 5.71, p < 0.01). Overall, 34% of our study population scored >60 on the DASS21-total score, whereas 29.04% scored >21 on the depression scale. Alarmingly, >40% of the women in the frequent interaction group scored in the extremely severe range of anxiety and depression. Moreover, in the regression analysis, out of all the factors analyzed, the extent of everyday interaction with male strangers, an increase in fear of sexual crimes, and a self-perceived increase in mental distress during the 18 months post-pandemic were found to be highly statistically significant predictors of mental distress not only for total DASS 21 but also for the sub-scales of depression, anxiety, and stress. In Pakistan, women experienced a rise in sexual harassment cases post-COVID-19. An increase in sexual harassment was found to be a predictor of negative mental health in the form of depression, anxiety, and stress.

Inferences about interdependence shape cooperation.

During social interactions in daily life, people possess imperfect knowledge of their interdependence (i.e., how behaviors affect each person's outcomes), and what people infer about their interdependence can shape their behaviors. We review theory and research that suggests people can infer their interdependence with others along several dimensions, including mutual dependence, power, and corresponding-versus-conflicting interests. We discuss how perceptions of interdependence affect how people cooperate and punish others' defection in everyday life. We propose that people understand their interdependence with others through knowledge of the action space, cues during social interactions (e.g., partner behaviors), and priors based on experience. Finally, we describe how learning interdependence could occur through domain-specific and domain-general mechanisms.

Adolescents Intentions of Self-presentation on Social Media

With the development of the Internet and the innovation of mobile network technology, the advent of the social network era has broken the time and space constraints in the traditional social mode, changed the traditional social mode, and extended the interpersonal interaction in people's daily life to the virtual space. The difference between the social network and traditional Internet interaction is that it not only allows strangers to meet and communicate with each other, but it also aims to make a virtual social platform to generate a mapping with real-life interpersonal relationships and make this mapping visible. The social network builds an equal, open, and decentralized communication platform for users. Everyone becomes a creator and communicator instead of a passive recipient and provides a platform for each user to present themselves. In this research, in order to study the impacts on adolescents' online self-presentation intentions, Theory of Planned Behavior (TPB) and media use frequency are regarded as independent variables to measure their behavioral intentions. Besides, a questionnaire was conducted randomly in 529 samples from Suzhou and Tianjin, China, of which only 206 samples were about adolescents. Then, the data were analyzed via SPSS. The results show that there is a positive relationship between online self-presentation motive and attitude, subjective norm and perceived behavior control, and media use frequency. Whats more, the other-related areas can testify to these results.

P299 Disability in newly diagnosed patients with Crohn′s Disease: initial results from the prospective CROCO (Crohn′s Disease Cohort) Study

Abstract Background CD is classically seen as a progressive disease leading to bowel damage and disability. Disability has been proposed by the Spirit-IOIBD consensus1 as an endpoint in disease modification trials. However, there is a paucity of data regarding disability in CD patients at diagnosis. Methods The “Crohn′s Disease Cohort Study” (CROCO) is an ongoing prospective cohort aiming to study the longitudinal evolution of bowel damage and disability following diagnosis of CD. All patients are included within 12 months following CD diagnosis and will be followed over 5 years with serial assessments of bowel damage and disability. At recruitment patients completed an IBD disability score questionnaire (DS),2 comprising several domains: mobility, self-care, major daily life activities, gastrointestinal-related problems, mental health and interaction with the environment. We here describe the baseline DS and its association with disease features, disease activity score (Harvey-Bradshaw Index), and biomarkers of disease activity, on the first patients recruited into CROCO. Results Ninety-four patients were recruited, of which 66 filled at least 80% of the questions in the DS questionnaire; of those 55% were male and median age at diagnosis was 30.6 [IQR 24.2;38.8]. The baseline visit occurred at a median time of 6 months [IQR 2.6;9.2] after CD diagnosis. Ileal involvement (L1/L3) was reported in 82% of patients; 68% had B1 phenotype, and 26% presented extra-intestinal manifestations. Overall, 32% of patients had been hospitalised, and 6% had a history of CD-related surgery. Regarding medication [from diagnosis to baseline], 55% received steroids, 56% immunosuppressants, and 65% Anti-TNF therapy. The median DS was 79 [IQR 67;108.2] (range: 49;198); only 2 patients (3%) patients presented DS&amp;gt;162 (the central value of the DS), indicating no or mild disability. No correlations were found between clinical or analytical biomarkers of disease activity at the time of recruitment (Table 1). Associations between disease features and DS are displayed in Table 2. A history of CD-related hospitalisation was associated with a significantly higher DS (103 [IQR 79;157] versus 76.5 [65.5;97], p=0.013). No other associations were observed. Conclusion In a cohort of newly diagnosed CD patients, disability was mostly mild and independent of disease activity, disease location or behaviour; around 1/3 required hospitalisation within the first year of diagnosis, which was associated with increased disability. These data add to the growing concept that newly diagnosed disease represents a window of opportunity for intervention.

Interpersonal Complementarity and Affect in Daily Life.

The current study examines the associations between interpersonal complementarity and affective reactions during social interactions in daily life, as well as contextual moderators of these associations. This research aims to understand how satisfaction/frustration of interpersonal motives (operationalized as interpersonal complementarity) impacts affect, using Contemporary Integrative Interpersonal Theory as a guiding framework. Participants (N = 227) rated actor and partner agency and communion in interpersonal interactions in 6 prompted surveys per day for 21 days. Results suggested that communal and agentic complementarity was associated with more positive affect valence, though this association was stronger for communal complementarity. Additionally, agentic complementarity impacted affect in cold interactions, while communal complementarity impacted affect in warm interactions, indicating that there are potentially more agentic motives driving cold interactions and communal motives driving warm interactions. An increase in communal complementarity was associated with an increase in affect arousal, while an increase in agentic complementarity was associated with a decrease in affect arousal, indicating affect arousal may communicate something other than satisfaction/frustration of motives. The moderating role of type of interaction partner was also explored. Overall, the results of this study support fundamental assumptions of Contemporary Integrative Interpersonal Theory.

ESTUDO SOBRE TREINAMENTO FÍSICO NA REGULAÇÃO DO METABOLISMO LIPÍDICO EM ADOLESCENTES OBESOS

ABSTRACT Introduction In proportion to the development of the economy, the problem of obesity among adolescents is also increasing. This abnormal lipid metabolism index can influence other physical diseases besides harming the social development of youth. Objective Investigate physical training and the regulation of lipid metabolism in adolescents, improving the metabolic index of obese youth. Methods 80 obese adolescents with equal numbers of both genders were randomly assigned into experimental and control groups. The experimental group received daily 80-min sports training (aerobics, walking, badminton, swimming, and other sports with low intensity and long duration) six times a week for one month, without distinction of exercise intensity or frequency for gender. A comparison method was performed between the groups before and after the intervention with indicators including body weight, BMI, fluid ratio, water measurement, waist, hip, skinfold thickness, FBG, CT, Tg, HDL - C, and LDL - C, among others. Results Physical training can effectively improve adolescents’ body shape. Blood indices and other indicators except for HDL-C positively correlate with this body shape. Physical training substantially improved lipid metabolism in obese adolescents. Conclusion The exercise regimen of this experiment proved to be simple and manageable, offering adolescents a healthier physical and more confidence in their daily study, life, and social interaction, but also reducing several diseases caused by obesity. Due to the ease of replication, the sample size can be expanded to universal conclusions, making it feasible to popularize.

Affect Recognition in Hand-Object Interaction Using Object-Sensed Tactile and Kinematic Data.

We investigate the recognition of the affective states of a person performing an action with an object, by processing the object-sensed data. We focus on sequences of basic actions such as grasping and rotating, which are constituents of daily-life interactions. iCube, a 5 cm cube, was used to collect tactile and kinematics data that consist of tactile maps (without information on the pressure applied to the surface), and rotations. We conduct two studies: classification of i) emotions and ii) the vitality forms. In both, the participants perform a semi-structured task composed of basic actions. For emotion recognition, 237 trials by 11 participants associated with anger, sadness, excitement, and gratitude were used to train models using 10 hand-crafted features. The classifier accuracy reaches up to 82.7%. Interestingly, the same classifier when learned exclusively with the tactile data performs on par with its counterpart modeled with all 10 features. For the second study, 1135 trials by 10 participants were used to classify two vitality forms. The best-performing model differentiated gentle actions from rude ones with an accuracy of 84.85%. The results also confirm that people touch objects differently when performing these basic actions with different affective states and attitudes.

Experiences of bowel symptoms in patients with rectal cancer after sphincter-preserving surgery: a qualitative meta-synthesis.

This study is to identify and synthesize the available evidence of bowel symptom experiences of patients with rectal cancer after sphincter-preserving surgery (SPS). This qualitative meta-synthesis was conducted following the Joanna Briggs Institute (JBI) qualitative systematic review methodology and reported following the Enhancing Transparency in Reporting the Synthesis of Qualitative Research (ENTREQ) guidelines. Seven databases were searched on 22 December 2021. The selected studies were reviewed by two independent reviewers, and disagreements were resolved by discussion or with a third reviewer. Seven qualitative articles were included in the meta-synthesis with 192 total rectal cancer patients. The review summarized 53 qualitative findings into three synthesized findings: (a) Patients experienced bowel symptoms and triggered additional physiological problems, and they underestimated bowel symptoms; (b) patients had many negative emotions, and their daily life and social interaction were disturbed; and (c) patients adopted strategies to adapt or control their bowel symptoms. According to the ConQual evidence grading approach, the confidence of the synthesized findings was rated as moderate to low. The bowel symptoms of patients with rectal cancer after SPS have troubled their lives. Timely acquisition of symptom-related knowledge and enhancement of their coping abilities are important for the control and management of bowel symptoms. Healthcare professionals should clearly understand the bowel symptoms that patients may experience after SPS and provide supportive care for patients to improve patients' self-management abilities and quality of life.

Communication and Social Interaction Experiences of Youths With Congenital Motor Speech Disorders.

The purpose of this study was to explore the communication and social interaction experiences of adolescents with congenital motor speech disorders due to cerebral palsy or Down syndrome, with the aim of identifying clinical and research needs to support the development and implementation of speech-language interventions. Five male youths (ages 14-18 years) with congenital motor speech disorders and one of their parents participated in face-to-face, semistructured interviews designed to understand communication and social experiences in daily life. Interviews were audio-recorded and orthographically transcribed offline. Content was coded according to topic areas emerging in the data. Themes were developed to illustrate the most salient and representative aspects of participants' experiences according to the phenomenological tradition that recognizes that participants are experts in their "lived experience." Participants described the youths' day-to-day communication experiences, including facilitators and barriers to successful social interactions. Thematic analysis revealed three main themes: (a) strong core relationships amidst sparse, superficial interactions in daily life; (b) the complicated picture of why; and (c) how speech-language pathologists can help. Participants reported that the impact of congenital motor speech disorders on social interactions and experiences became more apparent in adolescence than in earlier childhood. Addressing communication challenges to meet the unique social demands of this period requires tailored interventions that target multiple contributing factors beyond speech impairment, such as social communication skills, negative communication partner attitudes, and participation opportunities. Shifting practice toward a life participation approach to communication intervention stands to substantially improve the long-term social outcomes of adolescents with motor speech disorders.

An Analysis of Ecolexicons Found in Selected Petatah Petitih in Nagari Gunuang

Human use language in their interaction in daily life to convey or deliver their thoughts and communicate with each other. This research belonged to the descriptive qualitative research to find out ecolexicons and the description of each ecolexicon based on the knowledge of community in Nagari Gunuang using triple dimension of social praxis. Based on data analysis and discussion found 30 words belonged to ecolexicons. Afterward, the data were classified into three categories biotic flora, biotic fauna, and abiotic. The researcher found 28 biotic lexicons, 22 of them are categorized as flora lexicons and 6 of them are categorized as fauna lexicons. On the other hand, abiotic lexicon was found only 2 by the researcher. Lexicons about biotic flora are considered as the most dominant type of ecolexicons that found. Among 22 biotic flora lexicons, 4 of them are classified as death words because it no longer used in daily life and unrecognized by the informant or society.

Negative expectations regarding interpersonal interactions in daily life are associated with subclinical depressive symptoms in a student sample: A prospective experience sampling study

Dysfunctional expectations and interpersonal problems are associated with depression, so we measured expected emotions towards interaction partners and compared them with actual emotions. We hypothesized that, between persons, individuals with higher subclinical depression would display stronger, more stable, and less accurate negative expectations. Within persons, we hypothesized that momentary negative expectations would predict subsequent negative affect. Fifty-three students completed 6 days of Experience Sampling, consisting of one morning expectation-assessment (9 am), three assessments on actual interpersonal emotions (1 pm, 5 pm, 9 pm), and six random affect-assessments. We regressed expected emotions, experienced emotions, expectation fluctuations, and expectation violations on subclinical depression. Using mixed model analyses, we further examined whether negative expectations preceded negative affect, and whether expectation violations preceded adjustments of expectations. Higher subclinical depression predicted more negative expectations. Within persons, worse-than-expected interpersonal interactions preceded negative affect whereas better-than-expected interactions preceded reductions of negative expectations. Despite problems with skewed data, our approach appears well-suited to examine interpersonal expectations in vivo.

The Experiences of People With Glioma and Their Caregivers: Living With Uncertainty and Long Term Consequences (COBra Study)

Abstract AIMS Glioma, the most common primary brain tumour, has variable survival rates. Existing evidence describes detriment to quality of life from persistent symptoms/side effects, functional loss and feelings of disconnection, particularly in glioblastoma; however, there remains limited focus on the experience of longer-term survivors. This study aimed to ascertain the lived experience of people with glioma and their caregivers, part of a larger study identifying outcomes for a core outcome set for use in glioma trials (COBra study). METHOD Semi-structured interviews with UK glioma patients, or patient-caregiver dyads, analysed using Thematic Analysis. RESULTS Nineteen interviews were undertaken. Patients and caregivers described living with uncertainty long after diagnosis and treatment, including prognostic uncertainty and anxiety surrounding recurrence and worsening symptoms. Patients described an inability to plan long-term, struggling to return to normal activities, either due to progressive tumour symptoms, and/or treatment side effects. Long-term physical and psychological side effects were highly impactful; patients felt left alone to cope, with support following treatment dropping off rapidly. Patients/caregivers sought self-directed ways to cope, focusing on routine and achieving some normality. However, the physical and neurological effects of glioma and its treatment affected all aspects of daily life and social interactions, impacting on sense of wellbeing and quality of life. CONCLUSION People with glioma, and their caregivers, struggle with loss of normality and living with uncertainty long after diagnosis. They proactively engage in self-directed approaches towards mitigating these effects, but experience gaps in support after treatment finishes. Clinical follow up should target these aspects of assessment and intervention.

Tetramethylpyrazine in Chinese baijiu: Presence, analysis, formation, and regulation.

Traditional Chinese fermented baijiu is one of the six major distilled spirits consumed worldwide. It plays an important role in people's daily life and social interactions because of its taste, nutritional value, and various health functions. Tetramethylpyrazine (TMP), also known as ligustrazine, is not only an important compound related to the flavor of Chinese baijiu but also has special pharmacological effects. It gives the baijiu a nutty and baked aroma and provides baijiu with important health benefits. Recently, the nutritional, drinking, and health aspects of baijiu have attracted significant attention. Therefore, the study of TMP in baijiu is an important aspect of baijiu health research. This mini novel review summarizes the formation mechanism of TMP, along with the current research progress, analytical methods used, and regulation strategies associated with TMP in Chinese baijiu in recent years.

Moderate Effects of Organizational Commitments on Team Commitments and Negotiations on Conflict Handling (Empirical Study: Indonesian Government)

The conflict between teams is an interaction in the organization's daily life. To reveal the effect of negotiation and team commitment on conflict resolution (in integrating it) in the context of the construct of inter-team conflict and investigate how organizational commitment moderates the relationship between team negotiation and team commitment. The author conducted a questionnaire survey on employees in the Indonesian public sector with a sample of 224 responses. Structural equation modelling was used to analyze data and test hypotheses. Using Smart PLS 3.0. The results reveal that team commitment and negotiation positively relate to integrating behaviour. In addition, moderating organizational commitment to negotiation and team commitment was positively related to conflict handling behaviour when organizations have different orientations in their goals. Finally, higher conflict handling reinforces the positive effects of integrating negotiation and team commitment. The findings can help practitioners to predict team commitment, negotiation according to the organization and handling conflicts within the organization. This can allow practitioners to adjust their strategy and steer commitments and negotiations toward mutually beneficial conflict resolution outcomes. This study applies the theory of integrated conflict management due to team commitment and negotiation and empirically examines the relationship in the employee context. Moreover, this study reveals that organizational commitment moderates this linkage

The role of interparental relationship variability in parent–child interactions: Results from a sample of mothers of children with autism spectrum disorder and mothers with neurotypical children

AbstractObjectiveThe goal of this study was to examine how variability in interparental relationship functioning predicts the quality of parent–child interactions in daily life among families in which a child had autism spectrum disorder (ASD), and families of neurotypical children.BackgroundParent–child interactions predict a host of key outcomes for children, and one contributor to the health of parent–child interactions is the quality of the relationship between the parent couple. Yet, prior research has exclusively focused on how average levels of parental relationship functioning predicts parent–child interactions, which neglects the importance of variability in the interparental relationship.MethodDrawing on a sample of 167 mothers, one group with a child with ASD (n = 85), and the other group with a neurotypical child (n = 82), we examined how weekly variability in mothers' relational experiences with their partner predicted their interactions with their children in daily life using multilevel modeling.ResultsThe association between interparental relational variability and mother child‐interactions depended on mean levels of interparental relational functioning. Specifically, when mothers reported poor average relational functioning across a particular week, greater variability in their relationship across this same period was associated with benefits for mother–child interactions. This pattern was not seen in those with healthy interparental functioning. Moreover, moderation analyses suggested relational variability may be especially relevant for parent–child interactions of mothers of neurotypical children.ConclusionThese results suggest that the association between variability in parents' relational experiences and parent–child interactions depends upon mean levels.

Kajian Ayat-Ayat Manajemen: Isyarat Al-Qur’an Tentang Lingkungan Pendidikan

The educational environment or also known as Tri Centa Pendidikan as an Education Center consisting of family, school, and community is a place where formal and non-formal educational interactions take place. The family as the first place has the responsibility to provide the initial foundation in education that colors the daily life of a child's personal life towards adulthood for the rest of his life. Schools as formal educational institutions are entrusted with the responsibility to continue children's education in developing talents and interests so that they become self-directed. Both families, schools and communities play a very important role and are responsible for supervising, directing, and providing the education they have received from adults or the surrounding environment. These three educational environments will greatly determine the development of children, whether good or bad, the role of parents, teachers and the surrounding community will affect the child's development. imitating and playing an active role in maturation of children's personal development through social interactions in daily life without us realizing that children will grow and develop both physically and spiritually and continue to experience continuous changes throughout life.

COMPLAINING STRATEGIES USED BY THE EFL LEARNERS OF ENGLISH STUDY PROGRAM IN RIAU

Complaint commonly appears in daily life interaction (Sukyadi, 2011). People do not only provide words when they speak up but also deliver an action. The way how they complain is sometimes different. Hence, the study described in this article aimed to investigate the types of complaining strategies produced by the EFL learners of the English Study Program at Universitas Riau. The research was conducted in Pekanbaru. Research design used was a descriptive qualitative study accompanied by descriptive statistics. The participants of the research involved 36 EFL students of the English Study Program selected by using the cluster random sampling technique. The data were collected by using a DCT( Discourse Completion Task) system consisting of some situations in which students were requested to express their complaints. The result showed that the students mostly used direct complaint strategies. Subsequently, based on the overall strategies, the direct accusation strategy appeared as the strategy mostly employed by students in their daily interactions. It means that they prefered to give a direct and simple complaint by using a question to accuse the complainant directly. Moreover, they complain about something by using an Indonesian structural context as their L1, which was not appropriate in the English structural context as their L2. One of the strategies that were not used by the students was the direct strategy to condemn or curse the defendant’s actions because it was claimed as a harsh accusation.

Ecological and Convergent Validity of Experimentally and Dynamically Assessed Capacity for Social Contingency Detection Using the Perceptual Crossing Experiment in Adolescence.

The Perceptual Crossing Experiment (PCE) captures the capacity for social contingency detection using real-time social interaction dynamics but has not been externally validated. We tested ecological and convergent validity of the PCE in a sample of 208 adolescents from the general population, aged 11 to 19 years. We expected associations between PCE performance and (a) quantity and quality of social interaction in daily life, using Experience Sampling Methodology (ESM; ecological validity) and (b) self-reported social skills using a questionnaire (convergent validity). We also expected PCE performance to better explain variance in ESM social measures than self-reported social skills. Multilevel analyses showed that only self-reported social skills were positively associated with social experience of company in daily life. These initial results do not support ecological and convergent validity of the PCE. However, fueled by novel insights regarding the complexity of capturing social dynamics, we identified promising methodological advances for future validation efforts.

Penanaman Nilai-Nilai Keislaman Bagi Siswa di SMK Bina Mandiri Multimedia

Education is a learning process that is passed down from one generation to the next generation. Education that is side by side with the inculcation of Islamic values can shape the character of students who are akhlakul kharimah. Many of educational institutions that only provide knowledge transfer without any transfer of values has an impact on many of juvenile delinquencies that occur. Instilling Islamic values in adolescent students greatly influences the way students thinking, behave, and interaction in daily life. This service activity was carried out at the SMK Bina Mandiri Multimedia. The process of this activity is carried out by means of socialization and discussion. After participating in this activity, the students of SMK Bina Mandiri Multimedia better understand the need to instill Islamic values in the school environment and also apply them in daily life.
