Resetting FLOWERING LOCUS C Expression After Vernalization Is Just Activation in the Early Embryo by a Different Name
Authors: Finnegan E. Jean , Robertson Masumi , Helliwell Chris A.
Published: January 2021

The reproductive success of many plants depends on their capacity to respond appropriately to their environment. One environmental cue that triggers flowering is the extended cold of winter, which promotes the transition from vegetative to reproductive growth in a response known as vernalization. In annual plants of the Brassicaceae, the floral repressor, FLOWERING LOCUS C (FLC), is downregulated by exposure to low temperatures. Repression is initiated during winter cold and then maintained as the temperature rises, allowing plants to complete their life cycle during spring and summer. The two stages of FLC repression, initiation and maintenance, are distinguished by different chromatin states at the FLC locus. Initiation involves the removal of active chromatin marks and the deposition of the repressive mark H3K27me3 over a few nucleosomes in the initiation zone, also known as the nucleation region. H3K27me3 then spreads to cover the entire locus, in a replication dependent manner, to maintain FLC repression. FLC is released from repression in the next generation, allowing progeny of a vernalized plant to respond to winter. Activation of FLC in this generation has been termed resetting to denote the restoration of the pre-vernalized state in the progeny of a vernalized plant. It has been assumed that resetting must differ from the activation of FLC expression in progeny of plants that have not experienced winter cold. Considering that there is now strong evidence indicating that chromatin undergoes major modifications during both male and female gametogenesis, it is time to challenge this assumption.

Published: January 2021

Plant leaf respiration is one of the critical components of the carbon cycle in terrestrial ecosystems. To predict changes of carbon emissions from leaves to the atmosphere under a warming climate, it is, therefore, important to understand the thermodynamics of the temperature response of leaf respiration. In this study, we measured the short-term temperature response of leaf respiration from five different urban tree species in a subtropical region of southern China. We applied two models, including an empirical model (the Kavanau model) and a mechanistic model (Macromolecular Rate Theory, MMRT), to investigate the thermodynamic properties in different plant species. Both models are equivalent in fitting measurements of the temperature response of leaf respiration with no significant difference (p = 0.67) in model efficiency, while MMRT provides an easy way to determine the thermodynamic properties, i.e., enthalpy, entropy, and Gibbs free energy of activation, for plant respiration. We found a conserved temperature response in the five studied plant species, showing no difference in thermodynamic properties and the relative temperature sensitivity for different species at low temperatures (<42°C). However, divergent temperature response among species happened at high temperatures over 42°C, showing more than two-fold differences in relative respiration rate compared to that below 42°C, although the causes of the divergent temperature response remain unclear. Notably, the convergent temperature response at low temperatures could provide useful information for land surface models to improve predictions of climate change effects on plant respiration.
Exploring Teachers’ Satisfaction and Students’ Entrepreneurial Competencies in Four Entrepreneurial Programs Carried Out in Extremadura (Spain) Schools

Published: January 2021

The question of whether the entrepreneur is born or made, forces us to respond that the entrepreneurial culture clearly breaks with the myth that entrepreneurs are born. Currently, it is considered that entrepreneurial skills can be acquired like any other discipline and that is why it should be taught (Timmons, 2003). Their teaching and learning are key to the well-being of the teacher and to the positive achievement of the students. The entrepreneurial culture is an educational objective of developed societies and has its origin in the business culture (Peña Calvo et al., 2015). There are two current models, American and European (Erkkilä, 2000). The one that develops in the Extremadura region (Spain), based on the European model, tries to create a vital state in the participating students that enhances competences such as creativity, personal initiative or self-confidence, elements that try to generate a true motivation to undertake. The motivated, accomplished and positive teacher contributes to that achievement and achieving it favors the well-being of teachers. It’s a round trip. It is a “do ut des.” In our research, we evaluated four entrepreneurial culture programs in the classroom: “Junioremprende,” “Teenemprende,” “Experemprende,” and “Youthemprende.” The teachers involved in the programs are 356, and the valid questionnaires are 154. The students enrolled in the programs are 4800, and the questionnaires valid 1198. In the questionnaire, one of the key questions is “general teacher satisfaction,” with 17 common questions for all the programs. An essential question posed is: “I am satisfied with the achievements obtained by my students to participate in the program” The results of our research, according to a seven-point Likert scale, gives a very high degree of teachers’ satisfaction. Their satisfaction was centered on the perception of their teachings are conducive to the achievement of his students. The degree of teacher satisfaction for each of the programs and significantly means differences were found with Junior program resulted the more satisfied for teachers. For students, participation in the programs resulted in high development of entrepreneurial competencies. Similarly to teachers results, Junior program was found more significant in developing students’ entrepreneurial competencies indicating that entrepreneurial education is very appropriate for children. Findings of this study suggest that entrepreneurial education should be encouraged for students at every stage of education.
Personality Features in Obesity

Published: January 2021

Obesity is a widespread and broadly consequential health condition associated with numerous medical complications that could increase mortality rates. As personality concerned individual’s patterns of feeling, behavior, and thinking, it may help in understanding how people with obesity differ from people with normal-weight status in their typical weight-relevant behavior. So far, studies about personality and BMI associations have mainly focused on broad personality traits. The main purpose of this study was to explore the personality and health associations among a clinical group composed of 46 outpatients with overweight/obesity (mean age = 55.83; SD = 12.84) in comparison to a healthy control group that included 46 subjects (mean age = 54.96; SD = 12.60). Both the clinical and control groups were composed of 14 males and 32 females. Several personality and psychopathological aspects were assessed with the Personality Assessment Inventory (PAI). The results of the analysis of variance of aligned rank transformed (ART) showed that patients with overweight/obesity reported higher scores for Somatic Complaints, Depression, and Borderline Features than the control group. Logistic regression highlighted specifically that the subscales of the Borderline Features assessing the Negative Relationship contributed to the increased risk of belonging to the clinical group. For the purpose of this study, the role of gender was considered. The present findings highlight the importance of focusing on assessing personality functioning in the health context and on specific characteristics of interpersonal relationships to promote more tailored treatments.
Self-Efficacy, Psychological Flexibility, and Basic Needs Satisfaction Make a Difference: Recently Graduated Psychologists at Increased or Decreased Risk for Future Health Issues
Authors: Schéle Ingrid , Olby Matilda , Wallin Hanna , Holmquist Sofie
Published: January 2021

The transition from university to working life appears a critical period impacting human service workers’ long-term health. More research is needed on how psychological factors affect the risk. We aimed to investigate how subgroups, based on self-efficacy, psychological flexibility, and basic psychological needs satisfaction ratings, differed on self-rated health, wellbeing, and intention to leave. A postal survey was sent to 1,077 recently graduated psychologists in Sweden (≤3 years from graduation), response rate 57.5%, and final sample 532 (75% women and 23% men). A hierarchical cluster analysis resulted in a satisfactory eight-cluster solution. We identified two at-risk subgroups, displaying the lowest scores on health and wellbeing, and one potential low-risk subgroup with the highest ratings on said variables. The “Low risk?” group rated high on all three psychological constructs, a positive transition to working life, a work environment where resources balanced relatively high emotional demands, good health, and wellbeing. Almost the complete opposite ratings characterized the potential risk groups. “Quitting?” scored significantly higher than “Getting sick?” on self-efficacy and psychological flexibility as well as actively seeking new employment and reporting daily thoughts on leaving the profession. We suggest that a combination of low self-efficacy and psychological flexibility could increase the risk of individuals staying despite suboptimal working conditions. With combined higher self-efficacy and psychological flexibility, individuals in similar circumstances appear more inclined to quit. We conclude that the ways recently graduated psychologists rate their self-efficacy, psychological flexibility, and basic needs satisfaction appear to be reflected in their self-rated health and wellbeing.
Proffering Connections: Psychologising Experience in Psychotherapy and Everyday Life
Authors: Ekberg Stuart
Published: January 2021

Conversation analytic research has advanced understanding of the psychotherapeutic process by understanding how psychotherapy is organised over time in and through interaction between clients and therapists. This study progresses knowledge in this area by examining how psychological accounts of experience are progressively developed across a range of helping relationships. Data include: (1) approximately 30 h of psychotherapy sessions involving trainee therapists; (2) approximately 15 h of psychotherapy demonstration sessions involving expert therapists; and (3) approximately 30 h of everyday conversations involving close friends or family members. This article reports an analysis of techniques that are used to bring together two experiences that were discussed separately, to proffer a candidate connection between them. This proffering of candidate connections was recurrently used in psychotherapy. If confirmed by a client, a proffered connection could be used to develop a psychological account of a client’s experiences, which could then warrant some psychological intervention. In contrast, the proffering of connections was observed in only one of the everyday conversations included in the current study, where it was used to develop psychological accounts of experience. This shows that although proffering candidate connections is an everyday interactional practice, it appears to be used with greater frequency in psychotherapy, to advance its specific institutional aims.
An Investigation of the Coherence of Oral Narratives: Associations With Mental Health, Social Support and the Coherence of Written Narratives
Authors: Vanaken Lauranne , Bijttebier Patricia , Hermans Dirk
Published: January 2021

Research Questions

In a first research question, we examined whether the relations that are generally observed between the coherence of written autobiographical narratives and outcomes of mental health and social support, can be replicated for the coherence of oral narratives. Second, we studied whether the coherence of oral narratives is related to the coherence of written narratives.

Methods

Pearson correlations and t-tests were calculated on data of two separate studies to examine the research questions.

Results

First, only thematic coherence of oral narratives was significantly, although moderately, negatively associated to symptoms of depression, anxiety and negative social interactions. Second, the coherence of oral narratives was higher than the coherence of written narratives. Only the thematic coherence of oral narratives was positively associated with thematic and total coherence of written narratives. Furthermore, correlations between written and oral narratives were stronger for negative narratives as compared to positive narratives.

Discussion

The ability to elaborate emotionally and make meaning out of important life events in oral narratives is, to a certain extent, related to better mental health and more social support. Furthermore, thematic coherence may be a relatively stable feature of individuals’ narrative styles that is reflected in narratives of different modalities. Nonetheless, these topics need to be further researched to overcome present limitations.
The Organizational Commitment in the Company and Its Relationship With the Psychological Contract
Authors: Herrera Juan , De Las Heras-Rosas Carlos
Published: January 2021

Business organizations in their work environment, aspire to create a high level of performance and low levels of absenteeism and turnover. Organizational commitment is considered a key factor in achieving this objective, however, it can be conditioned by several factors, among which is the psychological contract. The literature has related the organizational commitment with the fulfillment of the psychological contract framing it as one of the explanatory variables. This work aims to investigate research trends on psychological contract and organizational commitment. For this purpose, bibliometric techniques and the software SciMAT have been used. 220 journal articles indexed in Web of Science (WoS) were analyzed. The findings indicate that the theme chosen for this review is valid. Based on the relationship between the two concepts, as the most recurrent themes, issues such as the sense of justice and the consequences of the violation of the psychological contract, normative commitment, HR management or job insecurity are addressed. However, in the last period analyzed (2015–2018), publications related to more sensitive topics to the present time emerge, such as the employability or the impact of these two concepts in the new generations (millennial and generation-Y) or the retention of talent. On the other hand, shortcomings are detected in the research on the ideologically charged psychological contract, the analysis of the organizational context or cultural and demographic factors in relation to both theoretical constructs. The contribution of this work lies in giving visibility to scientific results, which will serve business organizations as instruments for decision making in their labor management and, for the scientific community, as knowledge of the research spaces to explore.
Expression Authenticity: The Role of Genuine and Deliberate Displays in Emotion Perception
Authors: Zloteanu Mircea , Krumhuber Eva G.
Published: January 2021

People dedicate significant attention to others’ facial expressions and to deciphering their meaning. Hence, knowing whether such expressions are genuine or deliberate is important. Early research proposed that authenticity could be discerned based on reliable facial muscle activations unique to genuine emotional experiences that are impossible to produce voluntarily. With an increasing body of research, such claims may no longer hold up to empirical scrutiny. In this article, expression authenticity is considered within the context of senders’ ability to produce convincing facial displays that resemble genuine affect and human decoders’ judgments of expression authenticity. This includes a discussion of spontaneous vs. posed expressions, as well as appearance- vs. elicitation-based approaches for defining emotion recognition accuracy. We further expand on the functional role of facial displays as neurophysiological states and communicative signals, thereby drawing upon theencoding-decodingandaffect-inductionperspectives of emotion expressions. Theoretical and methodological issues are addressed with the aim to instigate greater conceptual and operational clarity in future investigations of expression authenticity.
The Influence of Quality on eWOM: A Digital Transformation in Hotel Management
Authors: Sánchez-González Gloria , González-Fernández Ana M.
Published: January 2021

There is no doubt that the use of Internet for purchasing products and services has constituted a crucial change in how people go about buying them. In the era of digital transformation, the possibility of accessing information provided by other users about their personal experiences has taken on more weight in the selection and buying processes. On these lines, traditional word-of-mouth (WOM) has given way to electronic word-of-mouth (eWOM), which constitutes a major social change. This behavior is particularly relevant in the services area, where potential users cannot in advance assess what is on offer. There is an abundant literature analyzing the effects of eWOM on different variables of interest in this sector. However, little is known about the factors that determine eWOM. Thus, the main objective of the present paper is to analyze the impact of two variables (objective quality and perceived quality) on eWOM. Both of them are crucial for potential customers in the process of finding hotel accommodations and they can motivate people to make such comments. The results demonstrate that these variables truly have a significant impact on whether or not users make comments on line. Moreover, it proved possible to observe certain differences according to the profile of the tourist involved and the destination where the hotel is located. In the current changing environment, this information is of great use for hotel managers in order to design strategies according to the type of guest they wish to attract.
Nature Archetypes – Concepts Related to Objects and Phenomena in Natural Environments. A Swedish Case
Authors: Ottosson Johan , Grahn Patrik
Published: January 2021

Do people classify nature in ways that can be described as archetypes? Could it be that these can be interpreted as health promotive? More and more researchers today suggest that archetypes can be used to analyze, describe, and develop green spaces. In parallel, an increasing number of research results since the 1980s have shown that human health and well-being are positively affected by stays in certain nature areas. The qualities in these nature areas which stand out to be most health-promoting are interpreted to be properties of nature that humans through evolution are prepared to perceive in a positive way. In this study, 547 respondents in southern Sweden answered a questionnaire on properties in natural areas. Through cluster analysis, these properties have been grouped into 10 types of nature and landscape. The 10 clusters are related to specific phenomena and places in Scandinavian nature, which could be described as archetypal. These natural phenomena and places are discussed, partly based on references to archaic Scandinavian mythology, Scandinavian lifestyle, and cultural canon, and partly on research on evolution, human preferences, and how nature can affect human health. We discuss how these nature archetypes evoke anxiety, fear, and distancing as well as calmness, tranquility, and connection. However, researchers have so far focused on how visits to natural environments have affected the sympathetic nervous system, and not realized the possibility of including the calm and connection system as well as the oxytocin in their explanatory models. In a follow-up article, we intend to develop a model for how the nature archetypes can interact with the calm and connection system.
Comparison of Goal Scoring Patterns in “The Big Five” European Football Leagues
Authors: Li Chunhua , Zhao Yangqing
Published: January 2021

The objective of the study was to compare goal scoring patterns among the “Big Five” European football leagues during the 2009/2010–2018/2019 seasons. A total of 18 pattern dimensions related to the offense pattern, the shooting situation and the scoring time period were evaluated. Kruskal–Wallis analyses revealed significant pattern differences among the five leagues. The Spanish La Liga showed a greater proportion of goals from throw-ins. The English Premier League had a higher tendency to score from corner kicks. The German Bundesliga had the greatest number of goals from counterattacks and indirect free kicks, and the Italian Serie A had the greatest proportion of penalties. Ligue 1’s scoring ability is weaker than that of the other leagues, especially Bundesliga. The Bundesliga had an overwhelming advantage in goals scored on big chances with assists, while the Premier League had an advantage in goals scored with assists that were not from big chances. However, the differences among the five leagues in the mean goals scored in the last 15 min and the goals from elaborate attacks and direct free kicks were not statistically significant. These results provide a valuable addition to the knowledge of different goal patterns of each league and allow us to better understand the differences among the leagues.

Authors: Carranza Rocío , Díaz Estrella , Sánchez-Camacho Carlos , Martín-Consuegra David
Published: January 2021

The development of information and communication technologies offers innovative opportunities to establish business strategies focused on customer value co-creation. This situation is especially notable in the banking industry. e-Banking activities can support competitive advantages. However, the adoption of e-banking is not yet well-established among consumers. In this sense, the technology acceptance model (TAM) is considered essential in studying consumer behavior applied to adopt a particular technology. According to the TAM model, this study analyses the factors which influence bank customers to adopt e-banking to facilitate their banking services and support the process of value co-creation. Consequently, the authors examine five main aspects of the technology adoption model to provide a broad understanding of bank customers’ consumption of e-banking. A partial least squares structural equation modeling (PLS-SEM) analysis is conducted to evaluate proposed relationships between factors and customers’ e-banking adoption.
Job Satisfaction of Fitness Professionals in Portugal: A Comparative Study of Gender, Age, Professional Experience, Professional Title, and Educational Qualifications
Authors: Ramos Liliana Ricardo , Esteves Dulce , Vieira Isabel , Franco Susana , Simões Vera
Published: January 2021

This research characterizes and compares the job satisfaction of fitness professionals in Portugal between genders, ages, professional experience, professional title, and educational qualifications. A total of 401 fitness professionals answered the online questionnaire Job Satisfaction Scale, which has 16 factors rated on a Likert scale with seven levels. The statistical analysis comprises descriptive and statistical tests to compare the results of two (t-test) or more (ANOVA) groups. Overall, the results demonstrated that fitness professionals were moderately satisfied with their work. The lower degrees of job satisfaction were concerning salary, opportunities for promotion, and stability at work. The highest levels of job satisfaction were related to the freedom to choose their work method, their work colleagues, the physical conditions of their workplace, and the opportunity to use their competencies. There were no differences in job satisfaction in terms of gender and a few differences between professional title and between educational levels. Regarding age and professional experience, the results showed significant differences in almost all factors, suggesting that, as fitness professionals get older and more experienced, their job satisfaction is greater. The results of this study suggest that even though fitness professionals are, in general, moderately satisfied with their work, some aspects can be improved by employers to increase their satisfaction levels. Such findings would assist employers in guiding the job satisfaction of their employees with consequent enhancements in the services provided by fitness professionals, which can increase participants’ retention in exercise fitness activities.
Cognitive Flexibility in Schoolchild Through the Graphic Representation of Movement
Authors: Urraca-Martínez MᵃLuz , Sastre-Riba Sylvia
Published: January 2021

Neuroconstructivism postulates the progressive complexity of mental representation over the course of cognitive development and the role of the graphic representation of movement in the transformation of mental schemas, cognitive flexibility, and representational complexity. This study aims to: (1) understand children’s resources in the drawing of movement (5–8 years); and (2) verify whether there are differences in the graphic representation of movement as an indicator of cognitive flexibility. The participants were N = 240 children aged 5–8 years; 1,440 drawings were collected representing 2,880 characters (both animate and inanimate) from six stories. The analysis consisted: (1) data quality control, using the kappa coefficient, and Generalizability Theory to test the instrument’s validity and reliability; (2) Multivariate General Analysis and Mixed Linear Analysis of the factors (age and stories); (3) Multivariate General Analysis of the graphic components: categories and microcategories, as well as the elements that make up the macrocategories: “Static,” “Indication,” and “Movement”; and (4) calculation of the generalizability coefficient (G-coefficient). The results show that: (a) age best explains variability, with a high effect size (η2 = 0.732) across all components (F = 153.445; p < 0.001), thus increasing its complexity and (b) at ages 6 and 7, “Indication” appears as a modulator of “Static” (age 5) toward “Movement” (age 8). The generalizability coefficient is optimal (0.995). It is concluded that changes in the initial graphic representation of movement may interactively transform mental representation, thus increasing cognitive flexibility and prompting teaching applications to optimize such changes.
Descriptions of Disordered Eating in German Psychiatric Textbooks, 1803–2017
Authors: Bergner Lukas , Himmerich Hubertus , Kirkby Kenneth C. , Steinberg Holger
Published: January 2021

The most common eating disorders (EDs) according to DSM-5 are anorexia nervosa (AN), bulimia nervosa (BN) and binge eating disorder (BED). These disorders have received increasing attention in psychiatry due to rising prevalence and high morbidity and mortality. The diagnostic category “anorexia nervosa,” introduced by Ernest-Charles Lasègue and William Gull in 1873, first appears a century later in a German textbook of psychiatry, authored by Gerd Huber in 1974. However, disordered eating behavior has been described and discussed in German psychiatric textbooks throughout the past 200 years. We reviewed content regarding eating disorder diagnoses but also descriptions of disordered eating behavior in general. As material, we carefully selected eighteen German-language textbooks of psychiatry across the period 1803–2017. Previously, in German psychiatry, disordered eating behaviors were seen as symptoms of depressive disorders, bipolar disorder or schizophrenia, or as manifestations of historical diagnoses no longer used by the majority of psychiatrists such as neurasthenia, hypochondria and hysteria. Interestingly, 19th and early 20th century psychiatrists like Kraepelin, Bumke, Hoff, Bleuler, and Jaspers reported symptom clusters such as food refusal and vomiting under these outdated diagnostic categories, whereas nowadays they are listed as core criteria for specific eating disorder subtypes. A wide range of medical conditions such as endocrinopathies, intestinal or brain lesions were also cited as causes of abnormal food intake and body weight. An additional consideration in the delayed adoption of eating disorder diagnoses in German psychiatry is that people with EDs are commonly treated in the specialty discipline of psychosomatic medicine, introduced in Germany after World War II, rather than in psychiatry. Viewed from today's perspective, the classification of disorders associated with disordered eating is continuously evolving. Major depressive disorder, schizophrenia and physical diseases have been enduringly associated with abnormal eating behavior and are listed as important differential diagnoses of EDs in DSM-5. Moreover, there are overlaps regarding the neurobiological basis and psychological and psychopharmacological therapies applied to all of these disorders.
Social Media Usage and Development of Psychiatric Disorders in Childhood and Adolescence: A Review
Authors: Cataldo Ilaria , Lepri Bruno , Neoh Michelle Jin Yee , Esposito Gianluca
Published: January 2021

Social media platforms, such as Facebook, Twitter, and Instagram, are now part of almost everyone's social life, especially for the newer generations. Children and teenagers grew up together with these Internet-based services, which have become an integral part of their personal and social life. However, as reported in various studies, psychological and psychiatric problems are sometimes associated with problematic usage of social media. The primary purpose of this review is to provide an overview of the cognitive, psychological, and social outcomes correlated with a problematic use of social media sites during the developmental stages, from age 10 to 19 years. With a specific focus on depression, anxiety, eating, and neurodevelopmental disorders, the review also discusses evidence related to genetic and neurobiological issues, together with the implications in clinical work and future directions under a multidisciplinary perspective. While the scientific community has made significant progress in enhancing our understanding of the impact of social media on teenagers' lives, more research integrating biological and environmental factors is required to fully elucidate the development of these disorders.
Evidence of Authorship on Messages in Facilitated Communication: A Case Report Using Accelerometry
Authors: Faure Patrick , Legou Thierry , Gepner Bruno
Published: January 2021

Facilitated communication (FC) belongs to augmentative and alternative methods of communication. Currently, FC is very rarely and unofficially used with people suffering from verbal/communicative disorders or neurodevelopmental disorders such as intellectual deficiency or autism spectrum disorder (ASD). FC consists of physical support exerted by a facilitator at the hand/wrist/forearm/elbow of a patient/participant, aimed at helping him/her to point at pictures/words, and sometimes to type letters/words on a keyboard. Given most of (but not all) validation studies using control procedures failed to confirm that ASD participants themselves were authoring the messages via FC, this method has been massively disputed and rejected. However, firm and definitive conclusions for/against the validity of FC requires more robust demonstrations, particularly when considering the motor participation of both protagonists. We present here a case report investigating the motor contribution of both protagonists during a typing process using the non-invasive technique of accelerometry. A 17-year-old boy diagnosed with congenital deafness, ASD, and developmental delay, and his facilitator, were equipped with small accelerometers fixed on their index finger, aimed at transforming index acceleration along the three spatial axes into electric signals. Typing on a PC keyboard was performed under three support conditions: hand support, forearm support, elbow support, plus a solo-typing condition. Accelerometric signals and video data were recorded during four FC sessions. We measured and compared the typing speed, the number/percentage of acceleration peaks produced by the participant or by the facilitator first, and those of “signal under detection threshold” in the facilitator, the time offset between acceleration peaks of both protagonists, and the difference of the amount of acceleration between them, across the different support conditions. Results indicate that in the hand support, most of the time, acceleration motions of the participant's index finger preceded those of the facilitator's index finger. Then, the more distal the physical support (i.e., farer from the participant's hand), the slower the speed of typing, the higher the percentage of “signal under detection threshold” in the facilitator, the bigger the motor contribution from the participant. Altogether, in all the support conditions, the participant's authorship or, at least, co-authorship on the messages seems warranted. Finally, accelerometry seems relevant to objectivize authorship or co-authorship in FC and delineate various forms of FC.
Current Addiction in Youth: Online Sports Betting

Published: January 2021

Background: Gambling landscape has changed in recent years with the emergence of online gambling (OG). Greater accessibility and availability of this betting modality can increase the risk of developing a gambling disorder (GD). Online sports betting (OSB) is currently the most common type of OG, but little is known about the clinical characteristics of OSB compared to slot-machine (SM) gamblers, the most common offline gambling disorder.

Methods: This was a prospective study conducted between October 2005 and September 2019, and included outpatients diagnosed with GD seen in a Pathological Gambling and Behavioral Addictions referral unit. Only patients with OSB and SM disorders were included. The main objective was to assess the clinical profile of OSB compared to SM gamblers, and to define clinical predictors for developing OSB gambling disorder. Logistic regression was performed to determine the effects of variables on the likelihood of this disorder.

Results: Among 1,186 patients attended in our Unit during the study period, 873 patients were included; 32 (3.7%) were OSB gamblers and 841 (96.3%) were SM gamblers. Overall, mean age was 45 ± 13 years and 94.3% were men. Compared to SM patients, OSB patients were younger (34.9 ± 9.5 vs. 45.3 ±13), more frequently single (43.8 vs. 20.6%) and had a university education level (43.8 vs. 4.5%); they were also more frequently non-smokers (18.7 vs. 66.7%) and had fewer psychiatric comorbidities (12.5 vs. 29.4%) than SM gamblers. GD duration before treatment initiation was shorter in OSB patients than in SM gamblers, most of them (81.3 vs. 42.4%) with ≤ 5 years of GD duration. OSB gamblers showed significant differences in weekly gambling expenditure, spending higher amounts than SM patients. Younger age (OR: 0.919; 95% CI: 0.874–0.966), university education level (OR: 10.658; 95% CI: 3.330–34.119), weekly expenditure >100€ (OR: 5.811; 95% CI:1.544–21.869), and being a non-smoker (OR:13.248; 95% CI:4.332–40.517) were associated with an increased likelihood of OSB gambling behavior.

Conclusions: We identified different profiles for OSB and SM gamblers. Younger age, university education level, higher weekly expenditure, and non-smoking habit were associated with OSB compared to SM disorders. Prevention strategies should help young people become aware of the severe risks of OSB.

Socioeconomic status is a strong predictor of normative development and well-being in young people. It is well-known that growing up in a socioeconomically disadvantaged context may lead to negative outcomes, both in childhood and in adulthood. Early intervention and prevention programmes are crucial for building resilience and improving health, well-being and equity. Bounce Forward is a school-based prevention programme implemented in Blackpool, a town in the United Kingdom facing multiple challenges. It was part of a whole town resilience approach and nascent global social movement known as the “Resilience Revolution.” Between 2017 and 2019, the programme was delivered in all Year 5 classes at every primary school in Blackpool (nschool = 36), reaching out to 3,134 students (ages 9–10; 50.4% male). The programme aimed to increase resilience in young people by building knowledge and skills about mental health and resilience through 10 sessions. In the current study, we longitudinally examined a range of protective factors, which are relevant to young people's resilience, as well as their mental health outcomes at three time points: before they participated in Bounce Forward, at the end of the programme, and 3–5 months later, when they started Year 6. The current sample included 441 Year 5 students (54.2% male) from 11 primary schools in Blackpool. Nineteen teaching staff also participated in the study and provided qualitative data regarding the impact of the programme on their students. Results showed improvement in some areas of young people's resilience after taking part in Bounce Forward. We also identified gender differences in several protective factors, indicating that boys may need further support. Teaching staff highlighted improvements in various areas; and also observed that their students have been using the strategies that they learnt from the programme. Altogether, findings suggested that young people benefitted from Bounce Forward. The programme is sustainable, offering a free to download teacher resource pack that allows schools to self-deliver it.

Introduction: Recent studies have confirmed that the management of cognitive dysfunction produces considerable positive effects in individuals with mild cognitive impairment (MCI), however, compliance with participation in various cognitive dysfunction management strategies remains scant in older adults with MCI. Health education programs can improve the level of knowledge of the disease effectively, though it remains unclear as to whether health education programs are sufficient to promote behavior changes of older adults with MCI in the community.

Objective: The study aims to provide insight into the effect of a trans-theoretical Model (TTM)-based health education program on increasing knowledge about mild cognitive impairment (MCI), compliance in cognitive dysfunction management, and other cognition-related health outcomes (general cognitive function, sleep quality, depression symptoms, apathy symptoms) for older adults with MCI.

Methods: This study is a single-blinded, randomized, prospective clinical trial. We will recruit 132 participants with MCI who will be randomly assigned to a TTM-based health education group and a standard health education group in a ratio of 1:1. The intervention group will receive a TTM-based health education program (1 session/week, 4–560 min/session for 8 weeks), while the control group will receive standard health education. Assessors blinded to participant allocation will conduct baseline, post-intervention, and 3-month follow-up assessments. Statistical analyses will consist of the Wilcoxon test, the Chi-square test, the T-test, and 2 (group) × 3 (time) ANOVA with a 5% cut-off for significance.

Discussion: Supposing the TTM-based health education program will provide validated community-based cognitive dysfunction management strategies for older adults with MCI, this would be a feasible approach to improve the compliance of participation in cognitive dysfunction management and the cognition-related health outcomes.

Prenatal Cannabinoid Exposure: Emerging Evidence of Physiological and Neuropsychiatric Abnormalities

Published: January 2021

Clinical reports of cannabis use prevalence during pregnancy vary widely from 3% to upwards of 35% in North America; this disparity likely owing to underestimates from self-reporting in many cases. The rise in cannabis use is mirrored by increasing global legalization and the overall perceptions of safety, even during pregnancy. These trends are further compounded by a lack of evidence-based policy and guidelines for prenatal cannabis use, which has led to inconsistent messaging by healthcare providers and medically licensed cannabis dispensaries regarding prenatal cannabis use for treatment of symptoms, such as nausea. Additionally, the use of cannabis to self-medicate depression and anxiety during pregnancy is a growing medical concern. This review aims to summarize recent findings of clinical and preclinical data on neonatal outcomes, as well as long-term physiological and neurodevelopmental outcomes of prenatal cannabis exposure. Although many of the outcomes under investigation have produced mixed results, we consider these data in light of the unique challenges facing cannabis research. In particular, the limited longitudinal clinical studies available have not previously accounted for the exponential increase in (-)-Δ9– tetrahydrocannabinol (Δ9–THC; the psychoactive compound in cannabis) concentrations found in cannabis over the past two decades. Polydrug use and the long-term effects of individual cannabis constituents [Δ9–THC vs. cannabidiol (CBD)] are also understudied, along with sex-dependent outcomes. Despite these limitations, prenatal cannabis exposure has been linked to low birth weight, and emerging evidence suggests that prenatal exposure to Δ9–THC, which crosses the placenta and impacts placental development, may have wide-ranging physiological and neurodevelopmental consequences. The long-term effects of these changes require more rigorous investigation, though early reports suggest Δ9–THC increases the risk of cognitive impairment and neuropsychiatric disease, including psychosis, depression, anxiety, and sleep disorders. In light of the current trends in the perception and use of cannabis during pregnancy, we emphasize the social and medical imperative for more rigorous investigation of the long-term effects of prenatal cannabis exposure.

Introduction: Workplace violence (WPV) against healthcare providers has severe consequences and is underreported worldwide. The aim of this study was to present the features, causes, and outcomes of serious WPV against healthcare providers in China.

Method: We searched for serious WPV events reported online and analyzed information about time, location, people, methods, motivations, and outcomes related to the incident.

Result: Serious WPV reported online in China (n = 379) were mainly physical (97%) and often involved the use of weapons (34.5%). Doctors were victims in most instances (81.1%). Serious WPV mostly happened in cities (90.2%), teaching hospitals (87.4%), and tertiary hospitals (67.9%) and frequently in Emergency Department (ED), Obstetrics and Gynecology Department (OB-GYN), and pediatric departments; it was most prevalent in the months of June, May, and February. Rates of serious WPV increased dramatically in 2014 and decreased after 2015, with death (12.8%), severe injury (6%), and hospitalization (24.2%) being the major outcomes. A law protecting healthcare providers implemented in 2015 may have helped curb the violence.

Conclusion: Serious WPV in China may stem from poor patient–doctor relationships, overly stressed health providers in highly demanding hospitals, poorly educated/informed patients, insufficient legal protection, and poor communication. Furthering knowledge about WPV and working toward curtailing its presence in healthcare settings are crucial to increasing the safety and well-being of healthcare workers.
