Introduction Robot-assisted surgery is often performed by experienced laparoscopic surgeons. However, this technique requires a different set of technical skills and surgeons are expected to alternate between these approaches. The aim of this study is to investigate the crossover effects when switching between laparoscopic and robot-assisted surgery. Methods An international multicentre crossover study was conducted. Trainees with distinctly different levels of experience were divided into three groups (novice, intermediate, expert). Each trainee performed six trials of a standardized suturing task using a laparoscopic box trainer and six trials using the da Vinci surgical robot. Both systems were equipped with the ForceSense system, measuring five force-based parameters for objective assessment of tissue handling skills. Statistical comparison was done between the sixth and seventh trial to identify transition effects. Unexpected changes in parameter outcomes after the seventh trial were further investigated. Results A total of 720 trials, performed by 60 participants, were analysed. The expert group increased their tissue handling forces with 46% (maximum impulse 11.5 N/s to 16.8 N/s, p = 0.05), when switching from robot-assisted surgery to laparoscopy. When switching from laparoscopy to robot-assisted surgery, intermediates and experts significantly decreased in motion efficiency (time (sec), resp. 68 vs. 100, p = 0.05, and 44 vs. 84, p = 0.05). Further investigation between the seventh and ninth trial showed that the intermediate group increased their force exertion with 78% (5.1 N vs. 9.1 N, p = 0.04), when switching to robot-assisted surgery. Conclusion The crossover effects in technical skills between laparoscopic and robot-assisted surgery are highly depended on the prior experience with laparoscopic surgery. Where experts can alternate between approaches without impairment of technical skills, novices and intermediates should be aware of decay in efficiency of movement and tissue handling skills that could impact patient safety. Therefore, additional simulation training is advised to prevent from undesired events.

There is a growing interest in whether and how parents’ experiences of discrimination may affect their children’s health and well-being. Considering that the intergenerational influence of discrimination on child well-being is still underexplored in China, there is an urgent need to determine whether children become depressed as a result of their parents’ discrimination experiences and to identify the pathways leading to their depressive symptoms. This study examined whether and how parents’ experiences of discrimination may lead to child (aged 10–15 years) depressive symptoms using data from the 2016 China Family Panel Studies (CFPS). The analytic sample included 1554 triads comprising children and both parents. Generalized structural equation modeling (GSEM) was employed to examine whether parents’ experiences of discrimination were related to child depressive symptoms through more serious parents’ depressive symptoms and greater tension between the two parents and between parents and their children. The analysis indicated that both mothers’ and fathers’ experiences of discrimination were indirectly related to children’s depressive symptoms through fathers’ and mothers’ depressive symptoms, parent–child quarreling, and interparental quarreling. The study also showed a crossover effect from fathers’ discrimination experiences to mothers’ depressive symptoms and indicated that fathers’ experiences of discrimination could influence children’s depressive symptoms through mothers’ depressive symptoms. The findings suggested that children whose parents were likely to suffer from discrimination, from either the father’s or mother’s side, could become vulnerable. Policies and practices targeting adult discrimination need to be extended to children to enhance parents’ awareness and improve their strategies for coping with discrimination.

Almost 70% grandparents play important roles in the parenting of grandchildren in China. Although several studies have investigated the influence of grandparenting on children, few studies have taken the mutual impacts between parental and grandparental caregivers on children into account. The present study investigated the different associations of mother’s and grandmother’s parental control (psychological and behavioral control), mother-child attachment, grandmother-child attachment, and child depressive symptoms between paternal and maternal groups from 201 grandparenting families. Results of mediating effect indicated the different associations between groups. In paternal group, significant crossover effect was shown in the association between paternal grandmother’s psychological control and mother-child attachment; mother’s psychological control and behavioral control were indirectly associated with child depressive symptoms through mother-child attachment. In maternal group, we did not find the same crossover effect as in paternal group, but maternal grandmother’s psychological control was indirectly associated with child depressive symptoms through maternal grandmother-child attachment. These findings expanded the crossover theory to grandmother-mother subsystem to reveal the mutual impacts on children between paternal and maternal group in grandparenting families.

We review the long standing problem of superfluid pairing in pure neutron matter. For the $s$-wave pairing, we summarize the state of the art of many-body approaches including different $nn$ interactions, medium polarization, short-range correlations and BCS-BEC crossover effects, and compare them with quantum Monte Carlo results at low-densities. We also address pairing in the $p$-wave, which appears at higher densities and hence has large uncertainties due to the poorly constrained interactions, medium effects and many-body forces., Comment: 15 pages, Mini-review for EPJ Special Topics, v2: minor changes

The present preregistered meta-analysis aimed to assess the evidence regarding the work-family interactions, as dyadic studies report them. The introduction differentiated between spillover (or intra-individual) effects and crossover (or inter-individual) effects by using dyadic studies. Following an online and reference list search, out of the initial 339 studies, 36 eligible articles reported correlations between one partner's variables and the other partner's variables. Analyses included 1504 effect sizes and used meta-analytical calculations and structural equation modeling. Both partners' well-being measures had small proportions of shared variance (i.e. shared variance up to 13.69%). The following analyses focused on the potential effects that could explain the shared variance of family-related well-being. There was little evidence of a crossover effect from one's work-related variables toward the partners' family-related well-being. Furthermore, analyses using structural equation modeling did not yield any results to support a crossover effect from one's work-family interaction toward their partner's well-being. These findings suggest that the literature needs new research studies regarding how family-related demands and resources are related to well-being and personal resources in the crossover processes.

Parenting stress of mothers has frequently been linked to negative child outcomes. According to Abidin’s stress model, this relationship may be explained by dysfunctional parenting behaviors. In this study, we scrutinized the effects of both mothers and fathers in the pathway from parenting stress through parenting behaviors to subsequent adolescent behavior problems. We expected the association between parenting stress and adolescent behavior problems to be partially mediated by maternal and paternal parenting behaviors. Further, we expected crossover effects, i.e., that parenting stress of one parent was related to the parenting behavior of the other parent. We applied a 3-wave longitudinal design using data from 441 adolescents (52% girls) and their parents (419 fathers; 436 mothers). Parents reported on parenting stress (adolescent age range = 10.9–16.3 years). Adolescents reported on perceived parental overreactivity and warmth (age range = 12.9–18.3) and their own internalizing and externalizing problems (age range = 15.9–21.3). Despite cross-sectional significant associations between parenting stress, parenting behavior, and adolescent behavior problems, we found no evidence of longitudinal linkages. One exception was maternal parenting stress, which positively predicted later adolescent externalizing problems. Consequently, the mediating role of parenting behaviors was not supported. We found no crossover effects in the pathway from parenting stress to parenting behaviors. The discrepancies between our longitudinal and cross-sectional findings raise questions about the actual impact that parents have on their children’s outcome. Though, targeting mothers’ parenting stress may help to reduce adolescent externalizing problems and its ramifications at least to some extent.

The high co-occurrence of intimate partner violence (IPV) and physical child abuse suggests that studying these forms of aggression simultaneously, bidirectionally, and longitudinally is critical. Guided by family systems theory, this study examined parent-child aggression (PCA) risk, IPV victimization, and child behavior problems as reported by mothers and fathers when their child was 18 months and at 4 years old, to evaluate whether negative processes can transmit across family subsystems (i.e., spillover hypothesis) and/or across individuals (i.e., crossover hypothesis). Results indicated that mothers’ PCA risk predicted their subsequent IPV victimization and their reported child behavior problems (i.e., spillover effects) as well as fathers’ reported IPV victimization (i.e., crossover effect). Maternal reports of child behavior problems also predicted mothers’ reported IPV victimization and fathers’ reported child behavior problems, indicating child-driven effects. Overall, mothers rather than fathers appear more vulnerable to harmful spillover effects. Findings underscore the need for early prevention and intervention given the complex, transactional nature of family violence.

The study explores how gender affects the relationships linking work-to-family conflict to job and life satisfaction among dual-earner spouses. Data were collected from 157 paired Chinese managers ...

In this paper, I propose that the specificity effect is able to improve or override weak crossover (WCO) phenomena, since [+specific] features associated with D-linking elements overtly move in wh-questions. These crossover configurations have been described in terms of syntactic factors. Postal (1971, 1993) and Wasow (1979) both refer to these kinds of crossover phenomena. Strong Crossover (SCO) violates the crossover principle or Binding Condition C. In contrast, WCO phenomena have remained marginal. The local constraints are not available to explain the variation associated with discourse connectivity, which includes WCO phenomena, or to capture pragmatic variation in context. From the perspective of semantic and pragmatic approaches, I suggest that specificity related to discourse context is able to explain the degree of the grammatical acceptability of wh-phrases in WCO configuration.

There are consistently high rates of sexual victimization and substance misuse among youth in the United States. Although there is a known relation between sexual victimization and substance use, there is a gap in the research regarding the magnitude and temporality of these associations. This study examined whether latent classes of sexual victimization and help-seeking attitudes longitudinally predict intentions of future substance misuse 7–10 months later. Students from nine Colorado high schools ( N = 533; M = age 16 years) completed surveys across two consecutive school semesters. Latent class analysis was used to identify classes of students who experienced at least one form of sexual victimization (e.g., sexual harassment, unwanted sexual contact) according to 13 sexual victimization items, and level of positive attitudes regarding help-seeking for sexual victimization. Classes were compared on demographic characteristics and for distal outcomes of likelihood of future substance misuse (cigarettes, alcohol, cannabis, prescription drugs, and electronic vaping products) using latent class regression, controlling for previous intentions to use. At Time 1, four classes of sexual victimization were identified with two main classes for comparison: low odds of experiencing sexual victimization (60.1% of sample) and high odds of endorsing all forms of sexual victimization (7.7% of sample). The high sexual victimization class had higher proportions of male and transgender students, compared to other classes. At Time 2 (7–10 months later), students in the high sexual victimization class reported a significantly greater likelihood of future cigarette ( p = .017) and prescription drug misuse ( p = .007) when compared to the low sexual victimization class. There was no evidence that having higher positive attitudes towards help-seeking resulted in lower intentions to use substances in the future. These findings highlight that addressing sexual violence in prevention programming may have crossover effects of reducing substance misuse and other forms of violence among youth.

Work–family conflict (WFC) has emerged as a challenging issue all over the world. Based on identity, scarcity, basic human values and crossover theories, we examined how life role salience, value of self-enhancement, gender and spouse’s emotional stability affect WFC. Data were collected using questionnaires from 167 dual-earner couples in Sri Lanka. All the variables, except for emotional stability, were measured from the focal employee concerned. Emotional stability was measured from the spouse. Four moderated multiple regressions were conducted to test the proposed model. This study found that a higher level of occupational role salience predicts work-to-family conflict. Further, results indicated that a higher value of self-enhancement increases work-to-family conflict, gender determines the level of family-to-work conflict, and spouse’s emotional stability directly crossovers to reduce family-to-work conflict of the other spouse. Hence, it is evident that not only individual factors but factors related to significant others such as spouses also create WFC. This research contributes to the advancement of the existing understanding on WFC as life role salience, values and crossover effect of spousal factors are still under-researched areas in work–family literature.

Burnout has been a prominent topic in the management research for over 30 years. Yet few studies have explored the conditions that foster burnout from managers to employees (indirect crossover). Based on the principle of behavioral plasticity, we propose that self-efficacy is an adaptive resource that enables employees to counter the potentially crossover effects of burnout (ie, emotional exhaustion and cynicism). This proposal is partially supported by the results of a longitudinal analysis of educators (principals and teachers): a moderating effect of employee self-efficacy was found, but only for emotional exhaustion, which is considered the basic individual stress dimension of burnout. More specifically, managerial emotional exhaustion was associated with lower emotional exhaustion over time in employees who reported higher self-efficacy, with the inverse association for employees with lower self-efficacy. This suggests that managers' emotional exhaustion can indirectly affect the experience of a congruent emotional state in their subordinates. Theoretical and practical implications are discussed.

Purpose This paper aims to examine how customers encounter consumption-based evolution between mobile and offline platforms together with temporal and crossover effects. Counter to research on customer satisfaction theory, which shows that satisfaction directly affects loyalty, the authors show that when shopping between mobile and offline platforms, customers differently evaluate loyalty compared to the traditional satisfaction and loyalty approach. Also, customers differently evaluate three types of service quality from online to offline (O2O) platforms and response dynamically to firm satisfaction and loyalty. Design/methodology/approach This study tests temporal, carryover and crossover effects using longitudinal data sets. Findings From crossover loyalty shifts, the findings show that the relationship between offline provider satisfaction (OS) and mobile provider loyalty (ML) during consumption periods is consistently significant with similar impact. However, mobile provider satisfaction (MS) during the same periods does not impact offline provider loyalty (OL) in the same manner, but differs considerably in terms of pattern of influence. Specifically, the findings show that this crossover effect increases over time even though statistical impact is insignificant. Thus, the carryover loyalty shift has a positive impact when it originally occurs in the offline platform but differs significantly when it originates via the mobile platform. Practical implications – this study offers valuable guidance to managers on how O2O platform-centric firms try to enhance satisfaction with consumption system that links to three types of service quality and loyalty. Research limitations/implications This study offers valuable insights into offline and ML. This is seen, however, as an experimental study and further research using the same method would enable cross-cultural comparators. Practical implications Insights can be drawn from the findings, enabling comparisons relative to service quality-satisfaction-loyalty linkage across dual platforms. The idea of evolution and progression over time is particular pertinent to business practice assuming data sets are gathered, maintained and analyzed. Originality/value Insights can be used from the research findings, including but not limited to comparing the service quality-satisfaction-loyalty linkage across dual platforms and providing firms with an explanation of temporal evolution.

PurposeThis research tested the crossover effects of a leader’s resilience on followers’ outcomes via followers’ resilience.Design/methodology/approachSurvey data from 87 leaders with 309 followers, collected in two waves in China, were used to test the multilevel mediation hypotheses.FindingsThe results indicated that (1) resilience could transfer from the leader to followers, and (2) leader’s resilience could further contribute to alleviating followers’ job burnout, and prompt citizenship behaviors by enhancing followers’ resilience.Originality/valueThis study adopted a top-down perspective to test the crossover effects of resilience, thus expanding the resilience literature illustrating its distinct influential mechanism through a vertically interpersonal perspective.

Background Crossover effects refer to the responses of a non-exercised contralateral limb. There is evidence of this effect, as it relates to muscle fatigue, strength, and stretch, but not as it relates to neuromodulation. Objectives To compare the crossover effects of percutaneous neuromodulation (PNM) on hip range of motion (ROM), observed in a straight leg raise (SLR) test, in asymptomatic participants with bilateral reduced hamstring flexibility, versus the neurodynamic sciatic sliding technique, hamstring stretching and mechanical stimulation of the sciatic nerve using a needle (without electrical stimulation). To evaluate the tensiomyographic changes between the two lower limbs after these interventions. Methods 80 participants with bilateral reduced hamstring flexibility were randomized into four groups: Stretching, Neurodynamic, PNM, and Needle groups. All interventions were performed on the right limb. Each participant’s leg was subjected to SLR testing and tensiomyography before and after the interventions. Results Each group improved their SLR values in the non-intervention limb compared to baseline values, but the PNM and Needle groups obtained higher values for the SLR test in the non-intervention limb compared with the Neurodynamic and Stretching groups. There were statistically significant differences for mean SLR measures between limbs pre- and post-intervention for all groups except the PNM group, suggesting crossover effects for PNM but not the other techniques studied. There were no differences in tensiomyographic assessments between groups or between sides, at baseline or upon completion of the study. Conclusion PNM produced benefits in the SLR test in the non-intervention limb and only 1.5 min was enough to obtain this effect. In addition, no technique interfered with muscle activation.

PurposeConflict between work and family is a significant issue for entrepreneurs. The purpose of this study is to explore the effect of entrepreneurial failure on both family–work conflict (FWC) and work–family conflict (WFC) and the moderating role of perceived control of time and organizational slack based on conservation of resources (COR) theory.Design/methodology/approachThis study used a questionnaire to explore the relationship between entrepreneurial failure, FWC/WFC, perceived control of time and organizational slack. Data were collected from the Chinese context in 2018 and as a result received 318 valid questionnaires, obtaining a response rate of 63.6 per cent.FindingsThe study finds that entrepreneurial failure has a significant relationship with FWC but a nonsignificant relationship with WFC and that perceived control of time and organizational slack moderate the relationship between entrepreneurial failure and FWC/WFC.Originality/valueThis study aligns the field of family–work (work–family) conflict and entrepreneurial failure. It addresses a research gap in the conflict literature by introducing one form of resource loss: entrepreneurial failure as a source of conflict between work and family based on COR theory and the work–home resources model. The study also enriches the literature on the social cost of entrepreneurial failure by exploring the crossover effect of entrepreneurial failure on conflicts in the family domain. Furthermore, the study advances the understanding of managing conflict between work and family after entrepreneurial failure.

This daily diary study addresses whether work colleague’s mindfulness at workplace relates to employee’s well-being and performance. Our sample was comprised by 63 couples of coworkers, who filled in quantitative web-based reports twice a day during a whole working week ((N = 126; 1260 occasions). Multilevel analysis was performed, thus showing that colleague’s daily mindfulness at the work context was positively linked to employee’s daily level of relaxation at home. This association was found to be partially mediated by the levels of daily positive affect that employees experienced during their working hours. Additionally, on those days in which employees reported higher levels of positive affect, they tend to foster organizational citizenship behaviours during the following day (colleague-reported). Previous day’s relaxation at home seemed to partially mediate this link. These results are the first ones to show a crossover effect of mindfulness between a couple of work colleagues, thus providing some evidence in favor of the idea that same hierarchical-level agents may benefit from interpersonal associations like the one we present. Moreover, our study expands the flourishing line of research about the within-person dynamics of mindfulness and the way it can be transferred between work and home indistinctively, on a daily basis. Finally, theoretical and practical implications of our findings are discussed.

Dual-income families are challenged by several issues in terms of conciliation between the working environment, the family context and the management of children. This paper, consistently with spillover and crossover hypotheses, aimed at examining the intermediate role of work-family balance, linking on work-family organizational support, work-to-family enrichment and conflict as predictors, and on family-life satisfaction of dual-income families’ both partners as final outcomes. It was expected that work-family organizational support would be related to lower work-to-family conflict and higher enrichment and, through them, with higher work-family balance; moreover, a positive association between work-family balance and family-life satisfaction of both partners was assumed. 390 double-income heterosexual couples participated in our study; 76.2% of the couples were parents. Structural equation modelling results showed that work-family balance was negatively predicted by work-to-family conflict and positively predicted by work-to-family enrichment. Furthermore, work-family organizational support positively predicted work-to-family enrichment, which also mediated its effect on work-family balance. Crossover and spillover effects were also confirmed, given that positive associations between work-family balance and family-life satisfaction of both partners were found. Implications for future research and organizational interventions aimed at both improving work-family balance and promoting greater satisfaction in family life are discussed.

Objective Demanding psychosocial work characteristics, such as high job demands, can have a detrimental impact on leisure–time physical activity (LTPA), with adverse consequences for employee health and well-being. However, the mechanisms and moderators of this crossover effect are still largely unknown. We therefore aimed to identify and test potential mediating and moderating factors from within and outside the work environment. Based on the previous research, we expected job demands to be negatively related to LTPA through fatigue. In addition, we expected that job control and worktime control would attenuate the relationship between job demands and fatigue. Furthermore, we hypothesized that autonomous exercise motivation and spontaneous action planning would attenuate the relationship between fatigue and LTPA. In addition to these cross-sectional hypotheses, we expected the same effects to predict a change in LTPA in the following year. Methods To investigate these assumptions, a preregistered longitudinal survey study was conducted among a large sample of Dutch employees in sedentary jobs. Participants reported on the constructs of interest in 2017 and 2018 (N = 1189 and 665 respectively) and the resulting data were analyzed using path analyses. Results Our cross-sectional analyses confirm a weak indirect, negative association between job demands and LTPA, via fatigue. However, this finding was not observed in our longitudinal analyses and none of the other hypotheses were confirmed. Conclusion This study shows that, among employees with relatively healthy psychosocial work characteristics (i.e., high job control), the evidence for an impact of these work characteristics on participation in LTPA is limited.

Military service members face substantial challenges due to war-related trauma exposure, including posttraumatic stress disorder (PTSD). Individuals with deficits in inhibitory control (IC) may have an increased risk of developing PTSD due to a reduced ability to regulate their cognitive responses to and disengage from trauma-related stimuli. After Deployment, Adaptive Parenting Tools (ADAPT) is a mindfulness-infused parenting program for military families that has also been found to have crossover effects on parental mental health. The present study examined whether fathers’ IC at baseline affected their response to this emotional skills–focused intervention and further influenced their PTSD symptoms 1 year later. The sample included 282 male National Guard and Reserve (NG/R) service members who had recently been deployed to Iraq or Afghanistan. Fathers were randomly assigned to either the ADAPT program or a control condition, with IC measured at baseline and PTSD symptoms measured at baseline and 1-year follow-up. Intent-to-treat analyses revealed no significant main effect of the intervention on fathers’ PTSD symptoms. However, fathers’ IC moderated intervention effects on PTSD symptoms, f(2)= 0.03. The intervention had more beneficial effects on reducing fathers’ PTSD symptoms for participants with low IC at baseline. These findings are consistent with compensatory effects in the risk moderation hypothesis, which suggests that prevention or intervention programs are more effective for high-risk subgroups.

This study examines crossover effects of adolescent substance misuse preventive interventions on academic success in college. It evaluates pathways of influence on college grades, via effects on school engagement, problem-solving skills, and substance misuse in high school. Data were collected as part of an Randomized Controlled Trial (RCT) evaluating a multicomponent intervention conducted in 28 school districts with middle school students. At age 19, study participants (N = 1,488) enrolled in college reported on college grades. The model fit the data, supporting hypothesized pathways of intervention impacts. Inclusion of a significant direct effect on college grades further improved model fit. Results support the potential for universal substance misuse preventive interventions delivered by community partnerships during middle school to yield effects on long-term academic success.

This study examines dual-earner couples to determine whether changes in work–family conflict predict changes in one’s own (i.e., actor effects) or partner’s (i.e., partner effects) health and well-being as well as gender differences in these relationships. Using data from 1,001 dual-earner couples in Wave 6 and Wave 8 of the German Family Panel survey (Pairfam), we found (1) significant actor effects for all outcomes, with stronger actor effects among men than women on mental health; (2) significant partner effects for life satisfaction and mental health, with stronger partner effects among men than women on life satisfaction; and (3) stronger actor effects than corresponding partner effects for life satisfaction and mental health. As work–family conflict has become a fact of life for many contemporary workers, our results contribute by highlighting the importance of using couple-level data and testing longitudinal crossover effects to provide a fuller understanding of such conflict’s health consequences.

This paper asks why scrambling is recognized as ''transparent'' movements in showing the remedy effect on the intervention phenomenon (e.g. ''LF''-intervention effects, island effects, Weak Crossover effects). Focusing on the non-trivial fact that scrambling induces D-linked interpretation in whquestions, I analyze scrambled elements with the same perspective to D-linked ones. When a wh-word is scrambled, as a D-linking effect, its base copy is inactive (incomplete before [+D] is realized) and its higher copy is active as the complete copy (complete at the outer vP,Spec or TP,Spec). Under this new analysis, we can account for well why scrambling across offending interveners is legitimate. Further, it provides a new perspective on scrambling.

The Journal of Studies in Language 35.1, 085-095. This study reports the results from a self-paced reading experiment that investigates Korean-English second language (L2) speakers’ online sensitivity to Principle C on online pronoun resolution. I examine this in the context of strong crossover (SCO) configurations in English to explore the effects of first language (L1) and proficiency on L2 processing. The findings show that proficiency appears to predict Korean-English L2 speakers’ use of target grammatical knowledge online. Highly-proficient Korean-English L2 speakers demonstrate sensitivity to the SCO constraint during online pronoun resolution in that they do not consider a fronted wh-phrase as a potential antecedent for a gender-matched pronoun that intervenes the wh-phrase and its gap. However, the SCO constraint does not restrict less-proficient Korean-English L2 speakers’ online pronoun resolution. The findings also suggest that L1 is not a determinant factor in L2 processing; that is to say, L2 processing is not fundamentally different from L1 processing. (Korea University)
