Effects of Lorentz symmetry violation on a relativistic scalar particle in quantum systems

In this paper, the relativistic quantum dynamics of a scalar particle under the effect of Lorentz symmetry violation determined by a tensor out of the Standard Model Extension is investigated. We see that the bound-state solutions of the modified Klein-Gordon equation can be obtained, and the spectrum of energy and the wave function depends on the Lorentz symmetry breaking parameters.

Features of nanocomposite powder paints spreading with the addition of aluminum oxide nanofibers

The paper studies the effect of violation of the spreading of powder paints when they are compounded with nanofibers of aluminum oxide. It is shown that with the addition of small fractions of aluminum oxide nanofibers equal to 0.05 wt%, the grains of the powder paint do not have time to wet each other, the crosslinking of the coating structure occurs up to this point, which is fixed by a characteristic granular texture. The paper also illustrates the features of the distribution of nanofibers of aluminum oxide in the coating. The increase in cohesion energy leads to a natural increase in the surface tension in the paint, which we observe in the form of the characteristic morphology of the coating. Investigation of coatings of a reference powder paint and a modified addition of aluminum oxide nanofibers) were carried out using an optical microscope. Separately, the morphology of the resin was investigated by scanning electron microscopy. Increasing the proportion of the flow agent based on acrylic compounds in the polyester resin from 0.8 to 1.8 wt% solves this problem, while the strengthening effect of nanofibers of alumina in the paint is retained.

Applications of the Schwarzschild\u2013Finsler\u2013Randers model

In this article, we study further applications of the Schwarzschild–Finsler–Randers (SFR) model which was introduced in a previous work Triantafyllopoulos et al. (Eur Phys J C 80(12):1200, 2020). In this model, we investigate curvatures and the generalized Kretschmann invariant which plays a crucial role for singularities. In addition, the derived path equations are used for the gravitational redshift of the SFR-model and these are compared with the GR model. Finally, we get some results for different values of parameters of the generalized photonsphere of the SFR-model and we find small deviations from the classical results of general relativity (GR) which may be ought to the possible Lorentz violation effects.

Grounds and consequences of waiver of the contract on the provision of tourist services

The purpose of the article is to clarify the legal nature, grounds, realization mechanism and consequences of waiver of the contract on the provision of tourist services. The research was conducted using such methods of scientific knowledge as dialectical, comparative, formal-legal, logical-legal. Based on the analysis of doctrinal approaches and regulations, it is established that the refusal of the agreement on the provision of tourist services is a measure of operational influence and a means of protecting the civil interest. The grounds for unilateral waiver of the contract differentiated into unconditional and those that are a consequence of violation of its terms. At the same time, it is stated that this subjective right is exercised in out-of-court procedure by sending a written (electronic) notice to the counterparty. In the context of the COVID-19 pandemic, it is proposed to give tourists the opportunity to choose between postponing the trip to another term and exercising withdrawal from the agreement. Particular attention is paid to the general and special consequences of lawful refusal. Based on the study, the authors made generalizations and conclusions about the state and prospects of improving the mechanism for exercising the right to unilateral waiver of the contract on the provision of tourist services.

Irrational behavior in dogs (Canis lupus familiaris): A violation of independence from irrelevant alternatives

We tested dogs for a violation of independence from irrelevant alternatives, which would indicate irrational behavior. In Experiment 1, we offered 10 dogs’ choices among alternative passages. The target passage led to more food than the competitor passage but required dogs to enter a narrower passage. The decoy passage asymmetrically dominated the competitor passage because although it contained a larger amount of food, it was narrower than the target passage. We found that dogs increased their preference for the target passage in the presence of the decoy passage, which violated the assumption of independence from irrelevant alternatives. Our second experiment controlled for energetic hunger state because previous findings had suggested that the violation effect might arise from changes in energetic state (Schuck-Paim et al., 2004). We provided supplementary feedings to each dog between each trial such that each dog consumed the same amount of food on each trial. The violation of independence from irrelevant alternatives effect persisted, though to a lesser degree than in Experiment 1. Cognitive implications are discussed.

When the past is strongly involved in the present: Examining the transference effects of past psychological contract violation on present deviance

Employees who experience psychological contract violation may quit the organization and join a new organization. However, how past psychological contract violation influences employees’ behavior in the new organization is less understood. Drawing on the social-cognitive model of transference, we hypothesize that past psychological contract violation is associated with lower psychological ownership and higher job insecurity in the new organization. These adverse transference effects can be buffered by institutionalized socialization tactics in the new organization. Furthermore, past psychological contract violation influences employees’ present deviant behaviors through psychological ownership and job insecurity in the new organization. These indirect effects are weaker when the new organization uses more (vs. less) institutionalized socialization tactics. The results across two field studies provide consistent and robust support for our hypothesized model. We discuss how our findings shed light on the transference effects of psychological contract violation and how to attenuate these harmful effects.

Women's Right to Land Between Collective and Individual Dimensions. Some Insights From Sub-Saharan Africa

Women represent a large part of the 2.5 billion people who depend on lands managed through customary, community-based tenure systems and are especially reliant on commons for their lives and livelihoods. They have very often limited and unsecured access to land and natural resources and tend to be excluded from decisions concerning them. Far from representing a homogenous group, they face varying challenges that are the result of multiple and intersecting forms of discrimination, whereby gender dynamics intersect with other characteristics, such as age, disability, ethnic origin, or socioeconomic status. Peasant and indigenous women, in many instances, face the compounded impact of the lack of recognition and violation of the collective rights of their communities, which is often the legacy of histories of colonization, conquest, dispossession and discrimination, and patriarchal norms, exacerbated by neoliberalism and the commodification of land and natural resources. The nexus between individual and collective rights is one of particular importance, but has received limited attention, including as regards the gendered effects of human rights violations of collective rights. In the present article, the nexus between collective and individual rights of peasant and indigenous women is illustrated by considering the experience surrounding the recognition and implementation of collective rights to land in Sub-Saharan Africa and the impact on women's right to land. The article argues that peasant and indigenous women's right to land is best protected through interventions aimed at guaranteeing both their collective and individual rights. There is a need to take into account and address simultaneously the barriers that indigenous and peasant women face with regard to their collective as well as their individual rights. These barriers include those ascribed to the discrimination and social, economic and political marginalization suffered by their peoples and communities, as well as those related to patriarchal power structures within and outside them. Addressing these barriers requires the respect, protection and fulfillment of both collective and individual human rights of women and a careful analysis of the interaction between these rights.

Search for CP violation in Ξb−→pK−K− decays

A search for $CP$ violation in charmless three-body $\Xi_b^- \to p K^- K^-$ decays is performed using $pp$ collision data recorded with the LHCb detector, corresponding to integrated luminosities of $1\,\text{fb}^{-1}$ at a centre-of-mass energy $\sqrt{s} = 7\,\text{TeV}$, $2\,\text{fb}^{-1}$ at $\sqrt{s} = 8\,\text{TeV}$ and $2\,\text{fb}^{-1}$ at $\sqrt{s} = 13\,\text{TeV}$. A good description of the phase-space distribution is obtained with an amplitude model containing contributions from $\Sigma(1385)$, $\Lambda(1405)$, $\Lambda(1520)$, $\Lambda(1670)$, $\Sigma(1775)$ and $\Sigma(1915)$ resonances. The model allows for $CP$-violation effects, which are found to be consistent with zero. The branching fractions of $\Xi_b^- \to \Sigma(1385) K^-$, $\Xi_b^- \to \Lambda(1405) K^-$, $\Xi_b^- \to \Lambda(1520) K^-$, $\Xi_b^- \to \Lambda(1670) K^-$, $\Xi_b^- \to \Sigma(1775) K^-$ and $\Xi_b^- \to \Sigma(1915) K^-$ decays are also reported. In addition, an upper limit is placed on the product of ratios of $\Omega_b^-$ and $\Xi_b^-$ fragmentation fractions and the $\Omega_b^- \to p K^- K^-$ and $\Xi_b^- \to p K^- K^-$ branching fractions.

Bias in estimated breeding-bird abundance from closure-assumption violations

The closure assumption of many abundance models, that individual animals are present throughout the survey season, often is inconsistent with field data. The effects of closure-assumption violations on estimators of abundance and associations between abundance and covariates are not fully understood. Furthermore, one’s definition of abundance affects these estimates. We used simulated data on breeding birds to explore how permanent, non-random immigration and emigration that violate the closure assumption affect estimates from N-mixture abundance models and naïve models (models that do not account for imperfect detection). This is the first work to evaluate the effect of permanent immigration and emigration on estimates from N-mixture models, and to compare these effects among definitions of abundance (initial, season-long, and superpopulation). We also collected and analyzed point-count data on breeding bird species in the Great Basin (USA) to evaluate the frequency of within-season movement. When detection probability was high (ρ ≥ 0.65), estimators of superpopulation abundance from N-mixture and naïve models were relatively unbiased. By comparison, in many cases, even relatively small violations of the closure assumption biased estimates of initial and season-long abundance by > 20%. Naïve abundance models generally were less biased than N-mixture models when ρ ≥ 0.65, but highly biased when ρ ≤ 0.4. In both model types, estimators of the association between abundance and an environmental covariate were minimally biased. The magnitudes of assumption violations tested in our simulations were consistent with those in our field data. Movement of individuals (availability) strongly affected detection probability of nearly all species and, in 7 of 34 species-region combinations, was temporally heterogeneous, suggesting that closure-assumption violations are common in our study system. Our results highlight that permanent movement of individuals within a season may be a substantial source of bias in studies of breeding birds that are based on count data, and that the definition of abundance affects the magnitude of these biases.

What a week! A moderated‐mediation crossover model for daily boundary violations at home and partner evening affect

Increasingly blurred boundaries allow work to breach home borders, disrupting personal tasks and goals which feel like violations to employees and thereby may trigger affective strain responses. Yet, the potential adverse effects of boundary violations at home on partner affective strain remains unexplored. Based on affective events and crossover theories, we considered the occurrence of violations at home as work-related stressors originating at home and thereafter evoking emotional strain in partners through employees' own affective strain response. Based on the differential reactivity model, we expected employee affective strain responses to boundary violations at home and subsequent emotional transmission to partners would be exacerbated during a period (i.e., one week) of high emotional strain when employees and partners are hyper-responsive to their home environments. Event data were collected for seven days from 69 employees and partners for 483 data points. Since the occurrence of homebound violations and associated effects on employees and partners likely fluctuates daily, a multilevel two-stage moderated-mediation model was tested. Results showed indirect effects of violations on partner affective strain through employee affective strain, with a backdrop of high emotional strain for the week moderating the affective event and crossover processes. Implications for scholars and organizations are discussed.

20. Biomechanical effect of facet joint violation on adjacent segment motion and disc strain following single level lumbar fusion with transpedicular screw and rod instrumentation

<h3>BACKGROUND CONTEXT</h3> Facet joint violation (FV) is a complication occurring while placing pedicle screws at the upper-most level using an entry point and trajectory too close to the superior facet joint. The incidence of FV has been reported up to be as high as 50%. However, little is known about how FV affects superior adjacent level spinal stability and especially intervertebral disc (IVD) strain after lumbar fusion. <h3>PURPOSE</h3> To investigate the biomechanical effects of FV in terms of mobility and disc surface strains at the upper level adjacent to L4-5 pedicle screw-rod fixation (PSR) in cadaveric specimens. The disc strain was studied with a new optical technique of soft tissue strain analysis (3D digital image correlation [DIC] technique). <h3>STUDY DESIGN/SETTING</h3> Biomechanic testing in human cadaveric spine specimens. <h3>PATIENT SAMPLE</h3> A total of 14 human cadaveric L3-S1 specimens. <h3>OUTCOME MEASURES</h3> 1. Upper adjacent segment range of motion. 2. Disc surface strain/stress. <h3>METHODS</h3> A total of 14 human cadaveric L3-S1 specimens were divided into two equal groups. L4-5 pedicle-rod fixation was performed in a different fashion in each group ie, facet joint preservation (FP) and facet joint violation (FV). The violation of the facet joint was defined by denuding the facet joint capsule and removing of the external cortical surface of the superior articular process with a 3 mm Leksell-rongeur. The entry point of these pedicle screws was located at the junction between the inferolateral aspect of the facet joint. All specimens were tested multi-directionally under pure moment loading (7.5Nm). DIC was performed with cameras positioned laterally (left side) to capture the change in principal disc strains (Pmax and Pmin) at the upper adjacent level (L3-4) under peak load. Optical motion tracking was simultaneously performed on the right side. The IVD region was divided into four similar sized quarters and included upper and lower endplates. Analysis of variance of upper adjacent level range of motion (ROM) and disc strain, normalized to intact, was performed between the groups. Statistical significant was set at P≤0.05. <h3>RESULTS</h3> Normalized ROM was significantly greater with FV than FP at upper adjacent level (L3-4) during right axial rotation (1.22 vs 0.99, 23% difference, p=0.047). Normalized IVD Pmax strains at the upper adjacent level (L3-4) were significantly greater with FV than FP in the anterior quadrant during right axial rotation (1.80 vs 0.83 (ratio to intact), 97% difference, p=0.003). However, there were no significant differences in ROM and disc Pmax or Pmin strains during flexion, extension and lateral bending. <h3>CONCLUSIONS</h3> Facet violations at the uppermost level of fusion construct during pedicle screw-rod fixation were associated with adjacent level torsional instability and the increase of IVD strain. This study suggested that the preservation of uppermost facet joint of fusion segment was helpful for alleviating adjacent segment mobility and stress concentrations of the IVD above the fusion segment. <h3>FDA DEVICE/DRUG STATUS</h3> This abstract does not discuss or include any applicable devices or drugs.

Effects of the hyperscaling violation and dynamical exponents on the imaginary potential and entropic force of heavy quarkonium via holography

The imaginary potential and entropic force are two important different mechanisms to characterize the dissociation of heavy quarkonia. In this paper, we calculate these two quantities in strongly coupled theories with anisotropic Lifshitz scaling and hyperscaling violation exponent using holographic methods. We study how the results are affected by the hyperscaling violation parameter theta and the dynamical exponent z at finite temperature and chemical potential. Also, we investigate the effect of the chemical potential on these quantities. As a result, we find that both mechanisms show the same results: the thermal width and the dissociation length decrease as the dynamical exponent and chemical potential increase or as the hyperscaling violating parameter decreases.

The Generative Mechanism of Boomerang Intention: From the Perspective of Legacy Identification

In addition to internal and external hiring, re-hiring as a third way to obtain employees, has become increasingly important in the case of volatile career and fierce competition in the talent market. Current studies on boomerang employment are scarce and mainly focus on boomerang performance, with little emphasis on the generation of boomerang employment. Based on social identity theory, this paper explores the generation of boomerang employment from the perspective of legacy identification, holds that legacy identification affects boomerang intention, and that both corporate prestige and psychological contract violation affect legacy identification through legacy identification. The cooperative possibility between the current and former organization will moderate the positive effect of both corporate prestige and psychological contract violation and boomerang intentions through legacy identification, such that the mediated effect is stronger when the cooperative possibility is higher. We find support for our hypotheses in a sample of 393 ex-employees in the industries of internet communications, financial, and the professional services. Hopefully, this study can provide the basis for the continuous attention and management of former employees, thus enrich turnover research and expand the connotation and boundary of human resource management.

Formal Contract Violation and Conflict: The Mediating Mechanism of Psychological Contract Violation

Although contract violation has a great negative effect on the supply chain relationship, few studies have deeply explored its influence. Based on the institutional theory, this study investigates how formal contract violation affects conflict in emerging economies. We extend the contract violation literature by suggesting that formal contract influents conflict through the psychological contract violation. The findings from a dataset of 186 firms in China indicate that formal contract violation has a positive effect on psychological contract violation. And psychological contract violation has a J-shaped relationship with conflict. Moreover, legal enforceability and relationship orientation strengthen the positive effect of formal contract violation on psychological contract violation.

Moral duty and equalization concerns motivate children's third-party punishment.

Although children enact third-party punishment, at least in response to harm and fairness violations, much remains unknown about this behavior. We investigated the tendency to make the punishment fit the crime in terms of moral domain; developmental patterns across moral domains; the effects of audience and descriptive norm violations; and enjoyment of inflicting punishment. We tested 5- to 11-year-olds in the United Kingdom (N = 152 across two experiments, 55 girls and 97 boys, predominantly White and middle-class). Children acted as referees in a computer game featuring teams of players: As these players violated fairness or loyalty norms, children were offered the opportunity to punish them. We measured the type (fining or banning) and severity of punishment children chose and their enjoyment in doing so. Children only partially made the punishment fit the crime: They showed no systematic punishment choice preference for disloyal players, but tended to fine rather than ban players allocating resources unfairly-a result best explained by equalization concerns. Children's punishment severity was not affected by audience presence or perpetrators' descriptive norm violations, but was negatively predicted by age (unless punishment could be used as an equalization tool). Most children did not enjoy punishing, and those who believed they allocated real punishment reported no enjoyment more often than children who believed they pretended to punish. Contrary to predictions, retribution was not a plausible motive for the observed punishment behavior. Children are likely to have punished for deterrence reasons or because they felt they ought to.

The Effect of Abusive Supervision on Organizational Identification: A Moderated Mediation Analysis

This study investigated the effect of abusive supervision on employee organizational identification by analyzing the mediating effect of psychological contract violation. In addition, it explored the moderating role of favoritism in the direct association of abusive supervision and organizational identification and the indirect effect through psychological contract violation. A total of 488 seasonal, immigrant, and part-time employees from family-run hotel organizations were surveyed during the data collection process. By utilizing Hayes’s macro, we found that abusive supervision and psychological contract violation had a significant negative effect on organizational identification. In addition, the results showed that psychological contract violation mediated the effect of abusive supervision on organizational identification and favoritism moderated the effect of abusive supervision on psychological contract violation. The findings highlight the detrimental effects of favoritism and abusive supervision on employee outcomes in the hospitality industry.

The Effects of Inhumane Treatment in North Korean Detention Facilities on the Posttraumatic-Stress Disorder Symptoms of North Korean Refugees.

ObjectiveThe study investigated the effects of severe human rights abuses in North Korean on Posttraumatic-stress disorder (PTSD) in North Korean Refugees (NKRs). MethodsThe study included 300 NKRs (245 females and 55 males) who completed self-report questionnaires that assessed PTSD, experiences of imprisonment, and exposure to inhumane treatment, by authorities in North Korea. A moderation analysis was conducted using a hierarchical multiple regression model to determine whether a moderation effect existed. In the next step, a post-hoc probing procedure of the moderation effect was performed using multiple regression models that included conditional moderator variables. ResultsThe influence of the frequency of being imprisoned on PTSD varied as a function of recurrent exposure to inhumane treatment or punishment by authorities. Experiences of imprisonment were associated with PTSD only among those who were exposed to recurrent violence, such as beating or torture, by North Korean authorities. ConclusionThe present findings highlight the significant effects of human rights violations, such as the inhumane treatment of prisoners in North Korea, on the PTSD of NKRs.
