- To understand human prosocial behaviour, one must consider not only the helpers and the requesters, but also the characteristics of the beneficiaries. To this aim, this articles reviews research on beneficiary effects in prosocial decision making, which implies that some human lives are valued higher than others. We focus on eight beneficiary attributes that increase willingness to help: (1) Temporal proximity, (2) Young age, (3) Female gender, (4) Misery, (5) Innocence, (6) Ingroup, (7) Identifiability (8) High proportion. We demonstrate that different psychological mechanisms explain different beneficiary effects, that the size and direction of beneficiary effects varies as a function of response mode (separate evaluation, joint evaluation, or forced choice), and outcome measure (attitudes or helping behaviour). We propose that beneficiary attributes differ in their evaluability, justifiability, and prominence, and conclude by discussing theoretical, moral, and applied aspects of beneficiary effects.

- Teacher education programs have the dual task of teaching specific subject content while also providing examples of how this content can be taught in schools. This task is especially important, and also problematic, when it comes to technology and science education, where hands-on components such as design/construction exercises, laboratory exercises, and excursions are central epistemic practices. When COVID-19 hit, Swedish universities were forced to change from campus-based teaching to online distance education, termed “emergency remote teaching (ERT).” The present study aims to investigate university teachers’ experiences of how hands-on components in science and technology education worked in the ERT mode that arose during the COVID-19 pandemic. The analysis was performed with a social semiotics and community of inquiry framework, and shows that both the type of instruction and the subject content were impacted. In particular, the reduced opportunities for students to apply scientific and technical methods and the reduced ability of teachers to determine whether the students had understood their instruction generated new ways of communicating and supporting the students’ learning. Therefore, analysis of meaning making in science and technology online-learning contexts needs to address the topics of the nature of science (NOS) and the nature of technology (NOT). An extended, three-dimensional model of meaning making is suggested.

- Serious games (SGs), are gaining prominence as a tool for early education at home as well as in school settings. Given the mixed effects of gamification on various aspects of users' lives, it is pertinent to study its broader effects on a child's pre-school and school years. Given the lack of consensus on a comprehensive measure that encapsulates these effects on an individual's routine functioning, the present study examined whether various engagement states in SGs use influence a relatively broader measure of users' functioning across significant life domains such as Quality of Life (QoL). It is argued that it would serve scholars, teachers, and parents better to understand the broader implications of SGs on children's overall QoL rather than isolated physiological and behavioral effects. Consequently, utilizing structural equation modeling, results from 335 parents of 2-10-year-olds in a developing country showed that cognitive and behavioral engagement in gamified applications appear to influence the child's QoL, but not affective engagement. Results are discussed in terms of the consequences of using game-based technology for a child's development, with far-reaching academic, personal, physical, and social implications not only for the school-going ages, but also for early teenage years. The results are promising in relation to QoL. The findings indicate the role modern technology plays in improving individuals' lives. The findings provide scholars, parents, and creators of SGs important information for their plan of action regarding children's exposure to SGs and making SGs a frequent aspect of the learning experience early in life.

- PROBLEM: The exact biochemical mechanisms that initiate labor are not yet fully understood. Nitric oxide is a potent relaxant of uterine smooth muscles until labor starts, and its precursor is L-arginine. Asymmetric (ADMA) and symmetric (SDMA) dimethylarginines, are potent NO-inhibitors. However, arginines (dimethylarginines and L-arginine) are scarcely studied in relation to labor and childbirth. We aimed to investigate arginines in women with spontaneous (SLVB) and induced (ILVB) term labor with vaginal birth and in women undergoing elective caesarean section (ECS).METHOD OF STUDY: Women at gestational week 16-18 were recruited to the population-based prospective cohort study BASIC at the Uppsala University Hospital, Sweden. Plasma samples taken at start of labor were analyzed for arginines, from SLVB (n = 45), ILVB (n = 45), and ECS (n = 45), using Ultra-High Performance Liquid Chromatography. Between-group differences were assessed using Kruskal-Wallis and Mann-Whitney U-test.RESULTS: Women with SLVB and ILVB had higher levels of ADMA (p < .0001), SDMA (p < .05) and lower L-arginines (p < .01), L-arginine/ADMA (p < .0001), and L-arginine/SDMA (p < .01, respectively <.001) compared to ECS. However, ILVB had higher ADMA (p < .0001) and lower L-arginine (p < .01), L-arginine/ADMA (p < .0001), and L-arginine/SDMA (p < .01) compared to SLVB. Results are adjusted for gestational length at birth and cervical dilatation at sampling.CONCLUSION: Our novel findings of higher levels of dimethylarginines in term vaginal births compared to ECS give insights into the biochemical mechanisms of labor. These findings might also serve as a basis for further studies of arginines in complicated pregnancies and labor.

- Prejudices tend to come as a package deal; people who are more racist tend to also be more sexist, and so on. Documentations of such attitudinal patterns - generalised prejudice - have a rich history, but the theoretical understanding thereof has been lagging. In recent years, we have seen clear theoretical advancement in the understanding of this phenomenon. We discuss classic premises in this research along with newer research that challenges some of the most ingrained ideas about generalised prejudice. For instance, we discuss research challenging the notions that generalised prejudice is an "us" versus "them" phenomenon, as well as a product of conservative ideology. We further argue that prejudice generalisations need to be studied at different levels of abstraction. Finally, we propose integrative perspectives on generalised and target-specific prejudice, with greater emphasis on processes of generalisation, rather than static generalised prejudice factors.

- Significance StatementA tightly regulated actin cytoskeleton attained through balanced activity of RhoGTPases is crucial to maintaining podocyte function. However, how RhoGTPases are regulated by geranylgeranylation, a post-translational modification, has been unexplored. The authors found that loss of the geranylgeranylation enzyme geranylgeranyl transferase type-I (GGTase-I) in podocytes led to progressive albuminuria and foot process effacement in podocyte-specific GGTase-I knockout mice. In cultured podocytes, the absence of geranylgeranylation resulted in altered activity of its downstream substrates Rac1, RhoA, Cdc42, and Rap1, leading to alterations of & beta;1-integrins and actin cytoskeleton structural changes. These findings highlight the importance of geranylgeranylation in the dynamic management of RhoGTPases and Rap1 to control podocyte function, providing new knowledge about podocyte biology and glomerular filtration barrier function.BackgroundImpairment of the glomerular filtration barrier is in part attributed to podocyte foot process effacement (FPE), entailing disruption of the actin cytoskeleton and the slit diaphragm. Maintenance of the actin cytoskeleton, which contains a complex signaling network through its connections to slit diaphragm and focal adhesion proteins, is thus considered crucial to preserving podocyte structure and function. A dynamic yet tightly regulated cytoskeleton is attained through balanced activity of RhoGTPases. Most RhoGTPases are post-translationally modified by the enzyme geranylgeranyl transferase type-I (GGTase-I). Although geranylgeranylation has been shown to regulate activities of RhoGTPases and RasGTPase Rap1, its significance in podocytes is unknown.MethodsWe used immunofluorescence to localize GGTase-I, which was expressed mainly by podocytes in the glomeruli. To define geranylgeranylation's role in podocytes, we generated podocyte-specific GGTase-I knockout mice. We used transmission electron microscopy to evaluate FPE and measurements of urinary albumin excretion to analyze filtration barrier function. Geranylgeranylation's effects on RhoGTPases and Rap1 function were studied in vitro by knockdown or inhibition of GGTase-I. We used immunocytochemistry to study structural modifications of the actin cytoskeleton and & beta;1 integrins.ResultsDepletion of GGTase-I in podocytes in vivo resulted in FPE and concomitant early-onset progressive albuminuria. A reduction of GGTase-I activity in cultured podocytes disrupted RhoGTPase balance by markedly increasing activity of RhoA, Rac1, and Cdc42 together with Rap1, resulting in dysregulation of the actin cytoskeleton and altered distribution of & beta;1 integrins.ConclusionsThese findings indicate that geranylgeranylation is of crucial importance for the maintenance of the delicate equilibrium of RhoGTPases and Rap1 in podocytes and consequently for the maintenance of glomerular integrity and function. A tightly regulated actin cytoskeleton attained through balanced activity of RhoGTPases is crucial to maintaining podocyte function. However, how RhoGTPases are regulated by geranylgeranylation, a post-translational modification, has been unexplored.

- Utilizing a large-scale cross-sectional survey, the present study tested the advanced psychometric properties of Fear of COVID-19 Scale (FCV-19S) in specific populations (i.e., primary and middle schoolteachers, and their students). The present study also examined the association between perceived fear of COVID-19 and psychological distress among home-room teachers (i.e., teachers who teach all their students in one classroom all day) and their students. The results among participants (11,134 teachers and 4,335 students) indicated good internal reliability of FCV-19S and excellent factorial validity with a two-factor structure utilizing these specific populations. Furthermore, the multilevel analysis showed that home-room teachers' psychological distress, but not fear of COVID-19, was positively associated with their students. In sum, the FCV-19S is a useful tool to assess the fear of COVID-19 on potentially vulnerable populations (i.e., primary/middle schoolteachers and their students). Future studies are encouraged to use the present study's findings to investigate possible underlying mechanisms for developing effective coping strategies and interventions.

- Research has revealed that teachers find teaching and assessing socioscientific argumentation (SSA) to be challenging. In this study, ten preservice science teachers (PSTs) tested a new Practical Assessment of Socioscientific Argumentation Model (PASM) that was developed to enhance skills in assessing SSA. The models' design is based on the Teacher oriented Assessment Framework. Here, we present the characteristics of PASM and examine how PSTs perceive that the use of PASM effects competences in assessing SSA. PASM is divided into multiple phases and requires PSTs to perform three roles: arguing for and against a given socioscientific issue, and assessing other PSTs' argumentation. It also includes group discussion and individual reflection phases. Two cycles of the model were performed, focusing on different issues (GMOs and nuclear power). Data were collected in the form of audio-recordings of group discussions, field notes from whole class discussions and the PSTs' written individual reflections. Thematic data analysis revealed that the PSTs discussed and reflected on four main themes: the focus of the assessment, the tools in PASM, the nature of PASM, and coping strategies. The nature of PASM, with iterative cycles and repeated reflections, expanded their views on assessing this kind of argumentation, making PSTs aware of quality criteria that should be included in assessment of SSA. We conclude that it is important to include training on assessing SSA in teacher education and that PASM could be a valuable tool for this purpose.

- Background: Discussion-based communication scenarios are present in many aspects of life. These can range from conversations with friends in a social setting to formal consultation processes and focus groups used by industry and government. However, reliance on speech does not easily permit the fair and equitable involvement of people who face communication-based accessibility challenges. Aim: This work aimed to understand the communication challenges present within social board games, how these challenges arise, and participants’ perceptions of the difficulties these challenges may cause. Method: We conducted four social gameplay sessions to understand what parts of discussion may cause communication challenges and what techniques are commonplace in overcoming these. Results: Our results highlight how group facilitation and conversation pacing are essential in promoting accessibility within discussion-type situations. Our analysis identified four themes that focused on speech and delivery, access strategies, viewing and position, balance of power, and awareness of others. Conclusions: Communication within board game scenarios is a complex area that creates several intersectional accessibility challenges. These challenges can impact how group communication is facilitated, how pacing and delivery relate to overall group understanding, and how an awareness of accessibility is critical in developing inclusive environments.
