    在这里,研究了具有新兴平面有序自旋团簇的自旋玻璃系统。混合B位烧绿石Gd2ScNbO7已通过多种技术合成和表征,包括X射线衍射,磁化率,μ子旋转放松,热容量和中子散射。尽管居里-魏斯温度为-3.93(3)K,指示净反铁磁相互作用,没有发现低至T=0.3K的长距离磁排序的迹象。出现无序的磁态,其相关长度为2.1(1)埃单四面体。对极化中子散射数据的RMC分析揭示了短程反铁磁有序性,其出现的XY自旋有序性类似于母体烧绿石化合物。Muon旋转放松,交流磁化率测量表明,磁化凝结成玻璃,在特定的fiC热中缺少10%的潜在熵。这种磁性基态类似于在Gd2Sn2O7中观察到的高于有序温度的状态,在低温下没有最终的远程订购。 .
    Here a spin glass system with emergent planar ordered spin clusters is investigated. The mixed B-site pyrochlore Gd2ScNbO7has been synthesized and characterized through a variety of techniques, including x-ray diffraction, magnetic susceptibility, muon spin relaxation, heat capacity and neutron scattering. Despite a Curie-Weiss temperature of -3.93(3) K, indicating net antiferromagnetic interactions, no signs of long ranged magnetic ordering are found down to T = 0.3 K. Instead, a disordered magnetic state emerges with a small correlation length of 2.1(1) Angstroms of single tetrahedra. A RMC analysis of the polarized neutron scattering data reveals short-range antiferromagnetic order with emergent XY spin ordering similar to the parent pyrochlore compounds. Muon spin relaxation, and AC susceptibility measurements confirm that the magnetization condenses into a glass, with 10 % of the potential entropy missing in the specific heat. This magnetic ground state is similar to what is observed in Gd2Sn2O7just above the ordering temperature, without the eventual long-range ordering at low temperature. .

    尽管自闭症谱系障碍(ASD)的患病率上升,对于解决其核心症状和相关症状的药物疗法,仍有大量未满足的需求。虽然一些非典型抗精神病药物已被批准用于管理相关的易怒和攻击性,它们的使用受到大量副作用的限制。这项研究的目的首先是开发行为措施来探索挫折,ASD大鼠产前丙戊酸(VPA)模型中的易怒和攻击表型。此外,我们研究了两种新机制的潜力,5-HT1B和TAAR1激动,缓解这些行为。对暴露于产前VPA的雄性后代进行了训练,以在提示的操作任务中实现稳定的表现,然后在操作挫折测试中进行药理学评估,瓶刷试验和居民闯入试验。暴露于VPA的大鼠表现出沮丧和易怒的行为,与对照组相比,攻击性也有所增加。在先前在操作测试中经历挫折事件的动物中,易怒的行为和攻击性进一步加剧。与载体相比,5-HT1B激动剂CP-94253或TAAR1激动剂RO5263397的单次施用减弱了挫折样行为。此外,在正常和挫折条件下,这两种激动剂都能降低易怒样行为。虽然CP-94253在两种条件下都降低了居民入侵者测试中的攻击性,RO5263397仅在先前经历挫折事件的大鼠中产生作用。我们的研究描述了以前未表征的挫折表型,烦躁,ASD大鼠产前VPA模型的侵袭性。给予选择性TAAR1或5-HT1B受体激动剂缓解了这些缺陷,有必要进一步探索ASD治疗中的两个目标。
    Despite the rising prevalence of autism spectrum disorder (ASD), there remains a significant unmet need for pharmacotherapies addressing its core and associative symptoms. While some atypical antipsychotics have been approved for managing associated irritability and aggression, their use is constrained by substantial side effects. This study aimed firstly to develop behavioral measures to explore frustration, irritability and aggression phenotypes in the rat prenatal valproic acid (VPA) model of ASD. Additionally, we investigated the potential of two novel mechanisms, 5-HT1B and TAAR1 agonism, to alleviate these behaviors. Male offspring exposed to prenatal VPA were trained to achieve stable performance on a cued operant task, followed by pharmacological assessment in an operant frustration test, bottle brush test and resident intruder test. VPA exposed rats demonstrated behaviors indicative of frustration and irritability, as well as increased aggression compared to controls. The irritability-like behavior and aggression were further exacerbated in animals previously experiencing a frustrative event during the operant test. Single administration of the 5-HT1B agonist CP-94253 or TAAR1 agonist RO5263397 attenuated the frustration-like behavior compared to vehicle. Additionally, both agonists reduced irritability-like behavior under both normal and frustrative conditions. While CP-94253 reduced aggression in the resident intruder test under both conditions, RO5263397 only produced effects in rats that previously experienced a frustrative event. Our study describes previously uncharacterized phenotypes of frustration, irritability, and aggression in the rat prenatal VPA model of ASD. Administration of selective TAAR1 or 5-HT1B receptor agonists alleviated these deficits, warranting further exploration of both targets in ASD treatment.

    家猫之间的社会紧张或冲突很常见,但是,因为它通常表现为微妙的行为变化,它可以不被注意;正是因为大多数迹象都是微妙的和无法识别的,所以使用了“紧张”一词。与紧张相关的慢性恐惧焦虑导致更明显的行为担忧和压力相关疾病,如果紧张情绪不能缓解,猫可能会面临看护者的放弃,甚至安乐死。\'2024AAFP内部张力指南:识别,预防和管理由美国猫科动物协会召集的猫科动物医学和行为方面的应用行为学家和临床专家组成的工作组撰写。目的是支持兽医专业人员理解猫之间的社会行为,更具体地说,在认识到猫之间的紧张关系时,防止或最小化其发生并管理压力源。在制定准则时,工作队修改了健康猫科动物环境的五个支柱,以提供一个框架,以协助预防或管理有两只或两只以上猫的家庭之间的紧张关系。因为猫科动物的社会行为经常被误解,该指南揭穿了10个常见的神话,这些神话有可能对伴侣猫的健康产生负面影响。广泛地说明了内部张力的视觉例子和附录详细介绍了一些案例研究,该指南还包括一份心理治疗药物的综合表格,以及详细的算法,概述了一种系统的预防方法,认识和解决相互间的紧张关系。包括逐步将新猫引入有一只或多只常住猫的家庭的方法,以进一步支持兽医,以及一系列促进客户教育的管理工具。
    Social tension or conflict between household cats is common but, because it often manifests as subtle behavioral changes, it can go unnoticed; it is precisely because most signs are subtle and unrecognized that the term \'tension\' is used. Where associated tension-related chronic fear-anxiety leads to more overt behavioral concerns and stress-associated disease, cats may face relinquishment by caregivers or even euthanasia if the tension is not relieved. The \'2024 AAFP intercat tension guidelines: recognition, prevention and management\' have been authored by a Task Force of board-certified veterinary and applied behaviorists and clinical experts in feline medicine and behavior convened by the American Association of Feline Practitioners. The aim is to support veterinary professionals in understanding social behavior between cats and, more specifically, in recognizing intercat tension, preventing or minimizing its occurrence and managing the stressors. In developing the Guidelines, the Task Force has modified the five pillars of a healthy feline environment to provide a framework to assist the prevention or management of intercat tension in households with two or more cats. Because feline social behavior is often misunderstood, the Guidelines debunk 10 common myths that have the potential to negatively impact the wellbeing of companion cats. Extensively illustrated with visual examples of intercat tension and an Appendix detailing a number of case studies, the Guidelines also include a comprehensive table of psychotherapeutic medications, and a detailed algorithm that outlines a systematic approach to preventing, recognizing and resolving intercat tension. A step-by-step approach to introducing a new cat into a household with one or more resident cats is included to further support veterinarians, and a range of management tools to promote client education accompany the Guidelines.

    目的:缺乏必要的图书馆资源对大多数大学的学术生活产生了巨大的影响。虽然先前的研究表明,缺乏诸如教科书之类的资源会影响学术成功,这项研究旨在为大学缺乏推荐教科书的连锁效应提供经验证据。
    方法:该研究使用了来自加纳五所公立大学的636名学生的定量数据集,这些学生使用结构良好的问卷进行收集。本研究采用探索性因素分析法,验证性因素分析,和偏最小二乘结构方程模型(PLS-SEM)来分析测量和结构模型。
    结果:研究得出的结论是,有限的图书馆资源(例如推荐的教科书)使图书馆用户感到沮丧,并最终产生诸如偷窃之类的反社会行为,隐藏,侵蚀书籍(或页面)。
    结论:本研究强调了提供充足的图书馆资源的重要性。它还指导图书馆经理,政策制定者,和学者对图书馆资源进行有效管理。
    OBJECTIVE: The lack of requisite library resources has an enormous effect on academic life in most universities. While previous studies have suggested that the lack of resources such as textbooks affects academic success, this study seeks to provide empirical evidence on the chain effect of the lack of recommended textbooks in universities.
    METHODS: The study uses a quantitative dataset from 636 students from five public universities in Ghana collected using well-structured questionnaires. The study adopts exploratory factor analysis, confirmatory factor analysis, and partial least squares structural equation modeling (PLS-SEM) to analyze the measurement and structural models.
    RESULTS: The study concludes that limited library resources (such as recommended textbooks) frustrate library users and eventually birth antisocial behaviors such as stealing, hiding, and eroding books (or pages).
    CONCLUSIONS: This study highlights the significance of providing adequate library resources. It also guides library managers, policymakers, and scholars to manage library resources effectively.

    背景:数字工具正在逐步重塑医院医疗保健专业人员(HCP)的日常工作。虽然这种转变有很大的希望,这会导致令人沮丧的经历,引起人们对对临床医生福祉的负面影响的担忧。
    目的:本研究的目的是全面探索HCP在日常生活中使用数字工具的生活体验。
    方法:对瑞士14家医院的24个医学专业的52个HCPs进行了定性深入访谈。
    结果:归纳主题分析揭示了4个主要主题:数字工具使用,工作流和流程,HCPs护理交付经验,以及数字化转型和管理变革。在这些主题中,出现了6个有趣的悖论,我们假设这些悖论可能部分解释了医院数字化面临的挑战的持续存在:效率的承诺和效率低下的现实,从面对面到界面的转变,杂耍挫折和奉献,信息获取和信任的幻觉,工作流程和护理路径的复杂性和交叉点,以及影子IT的机遇和挑战。
    结论:我们的研究强调了承认和考虑HCP的经验以支持医疗保健技术的转变并避免或减轻数字化可能带来的任何潜在负面经验的核心重要性。HCP的观点增加了对医疗保健中长期存在的信息学问题的相关见解,并可能提出应对未来挑战时要遵循的新策略。
    BACKGROUND: Digital tools are progressively reshaping the daily work of health care professionals (HCPs) in hospitals. While this transformation holds substantial promise, it leads to frustrating experiences, raising concerns about negative impacts on clinicians\' well-being.
    OBJECTIVE: The goal of this study was to comprehensively explore the lived experiences of HCPs navigating digital tools throughout their daily routines.
    METHODS: Qualitative in-depth interviews with 52 HCPs representing 24 medical specialties across 14 hospitals in Switzerland were performed.
    RESULTS: Inductive thematic analysis revealed 4 main themes: digital tool use, workflow and processes, HCPs\' experience of care delivery, and digital transformation and management of change. Within these themes, 6 intriguing paradoxes emerged, and we hypothesized that these paradoxes might partly explain the persistence of the challenges facing hospital digitalization: the promise of efficiency and the reality of inefficiency, the shift from face to face to interface, juggling frustration and dedication, the illusion of information access and trust, the complexity and intersection of workflows and care paths, and the opportunities and challenges of shadow IT.
    CONCLUSIONS: Our study highlights the central importance of acknowledging and considering the experiences of HCPs to support the transformation of health care technology and to avoid or mitigate any potential negative experiences that might arise from digitalization. The viewpoints of HCPs add relevant insights into long-standing informatics problems in health care and may suggest new strategies to follow when tackling future challenges.

    早期生活压力可能导致心理生理功能的终身损害,包括情感和奖励制度。奖励幅度的不可预测的减少会产生负面的情绪状态(沮丧),这可能与精神疾病的易感性有关。我们在青少年和成年大鼠中评估了两种性别的母亲分离(MS)是否会改变应对以后意外减少奖励的能力。将Wistar大鼠的碎片分为对照组(未处理-NH)或接受MS。训练动物寻找含糖谷物颗粒;后来减少了数量。到达奖励相关区域的延迟增加表明更无法调节挫折。评估背侧海马(dHC)和基底外侧杏仁核(BLA)的NMDA受体亚基(GluN2A/GluN2B)的蛋白质水平,突触素,PSD95、SNAP-25和CRF1。我们发现成年MS男性更容易受到奖励减少的影响,以及dHC中GluN2A降低和GluN2B免疫含量增加。MS女性和青少年与对照组没有差异。我们得出的结论是,MS增强了男性对挫败感的反应。GluN2A和GluN2B亚基在dHC中的比例变化可能与更强,更难以更新,对厌恶经历的记忆。
    Early life stress may lead to lifelong impairments in psychophysiological functions, including emotional and reward systems. Unpredicted decrease in reward magnitude generates a negative emotional state (frustration) that may be involved with susceptibility to psychiatric disorders. We evaluated, in adolescents and adult rats of both sexes, whether maternal separation (MS) alters the ability to cope with an unexpected reduction of reward later in life. Litters of Wistar rats were divided into controls (non handled - NH) or subjected to MS. Animals were trained to find sugary cereal pellets; later the amount was reduced. Increased latency to reach the reward-associated area indicates higher inability to regulate frustration. The dorsal hippocampus (dHC) and basolateral amygdala (BLA) were evaluated for protein levels of NMDA receptor subunits (GluN2A/GluN2B), synaptophysin, PSD95, SNAP-25 and CRF1. We found that adult MS males had greater vulnerability to reward reduction, together with decreased GluN2A and increased GluN2B immunocontent in the dHC. MS females and adolescents did not differ from controls. We concluded that MS enhances the response to frustration in adult males. The change in the ratio of GluN2A and GluN2B subunits in dHC could be related to a stronger, more difficult to update memory of the aversive experience.

    了解学习者如何调节自己的情绪和参与元认知策略对于促进自我调节学习至关重要,特别是在以技术为媒介的学习中。本研究考察了两种情绪调节(ER)策略之间的时间关系,重新评估和压制,挫败感,并将进度监控用作元认知策略,在金融知识教育游戏的背景下。这项研究涉及82名大学生,他们的沮丧程度,进度监控行为,在学习任务期间的各个时间点评估ER策略。研究结果表明,在学习任务期间,重新评估和抑制的使用都减少了。此外,两种ER策略都与挫折感负相关,尽管重新评估和挫折之间的关系随着时间的推移而减弱。挫折与进度监测呈负相关,表明有效的情绪调节可以通过保持认知资源的可用性来帮助维持元认知策略的参与。值得注意的是,抑制和进展监测显示出随着时间的推移而增加的正相关关系,强调抑制在扩展学习任务中的潜在有用性,尽管与重新评估相比,其有效性普遍较低。结果强调了在扩展学习过程中应用ER策略时考虑时间动力学的重要性。提出了对设计以技术为媒介的学习环境和教育干预措施的实际意义。
    Understanding how learners regulate their emotions and engage in metacognitive strategies is crucial for fostering self-regulated learning, particularly in technology-mediated learning. This study examines the temporal relationships between two emotion regulation (ER) strategies, reappraisal and suppression, frustration, and use of progress monitoring as metacognitive strategy, within the context of an educational game on financial literacy. The study involved 82 undergraduate students whose levels of frustration, progress monitoring behaviour, ER strategies were assessed at various points during the learning task. Findings revealed that the use of both reappraisal and suppression decreased during the learning task. Additionally, both ER strategies were negatively associated with frustration, although the relationship between reappraisal and frustration diminished over time. Frustration was negatively related to progress monitoring, indicating that effective emotion regulation can help maintain engagement in metacognitive strategies by keeping cognitive resources available. Notably, suppression and progress monitoring showed a positive relation that increased over time, highlighting the potential usefulness of suppression in extended learning tasks, despite its generally lower effectiveness compared to reappraisal. The results highlight the importance of considering temporal dynamics in the application of ER strategies during extended learning. Practical implications for the design of technology-mediated learning environments and educational interventions are proposed.

    背景:在第一和第二阶段的分娩过程中可能会出现延长的进展,并可能导致负面的分娩经历。然而,以前的研究主要集中在数量方面或整体出生经验,人们对女性长期被动的第二阶段的经历知之甚少。
    目的:描述未分娩妇女长期被动第二产程的生活经历。
    方法:对15名未分娩妇女进行了持续3小时或更长时间的被动第二阶段的定性研究。使用基于描述性现象学的主题分析对数据进行分析。
    结果:分析得出了四个主题:“未知阶段”,这意味着处于女性缺乏意识的阶段。“对身体能力的信任和不信任”代表了阴道分娩的心态以及无能为力和自我负罪感。主题“失去控制”包括挫折的经历,疲劳,不得不否认身体的本能。“通过在场和参与提供支持”表示通过助产士在分娩室的存在提供支持,虽然也有情绪或身体缺席的描述。
    结论:这些发现有助于根据女性的生活经历理解长期劳动,并增加了对长期被动第二阶段的认识。这项研究强调,妇女需要通过信息获得支持,存在,和鼓励继续控制。在分娩准备期间,包括有关被动第二阶段的知识以及分娩期间的意外或复杂情况可能是有益的,比如长时间的劳动。
    BACKGROUND: Prolonged progress can occur in the first and second stages of labour and may contribute to a negative birth experience. However, previous studies have mainly focused on quantitative aspects or overall birth experience, and little is known about women\'s experiences of a prolonged passive second stage.
    OBJECTIVE: To describe the lived experiences of a prolonged passive second stage of labour in nulliparous women.
    METHODS: A qualitative study was conducted with 15 nulliparous women with a passive second stage lasting three hours or more. Data were analysed using thematic analysis based on descriptive phenomenology.
    RESULTS: The analysis resulted in four themes: \"An unknown phase\" that entailed remaining in a phase that the women lacked an awareness of. \"Trust and mistrust in the body\'s ability\" represents the mindset for vaginal birth as well as feelings of powerlessness and self-guilt. The theme \"Loss of control\" included experiences of frustration, fatigue, and having to deny bodily instincts. \"Support through presence and involvement\" signifies support through the midwife\'s presence in the birthing room, although there were also descriptions of emotional or physical absence.
    CONCLUSIONS: The findings contribute to the understanding of prolonged labour based on women\'s lived experiences and add to the body of knowledge about the prolonged passive second stage. This study highlights that women need support through information, presence, and encouragement to remain in control. It can be beneficial during birth preparation to include knowledge about the passive second stage together with unexpected or complicated situations during birth, such as prolonged labour.

    大脑是一个沮丧的系统,其中包含名为沮丧的冲突链接安排。挫败感作为混乱的根源阻止了系统进入低能状态,并为大脑网络组织提供了灵活性。在这项研究中,我们试图确定大脑中挫折形成的模式,连接,规范网络,和半球。我们发现挫折形成没有统一的模式。一些皮层下元素在挫折形成中起积极作用,尽管许多皮质元素的贡献很低。令人沮丧的连接主要是网络之间的连接,三重挫折主要形成在三个不同的规范网络的三个区域之间。我们没有发现大脑半球之间的任何显着差异,也没有发现各个生命周期的挫败感形成模式之间的任何明显差异。对于那些研究大脑链接组织的人来说,我们的结果可能是有趣的,对于那些想要操纵大脑网络的人来说是有希望的。
    大脑网络分析方法通常忽略链接的迹象。挫折是一种令人着迷的现象,指的是已签名链接的冲突安排。作为不稳定的根源,它可以提供有关更改网络组件的有价值的信息。它可以指定哪些大脑网络元素打算驱动大脑网络改变。因此,我们试图确定大脑网络中挫折形成的模式,哪些大脑网络元素更沮丧,哪些元素更不沮丧。我们提供了一些区域层面的挫折形成图,连接,规范网络,和半球。引入的挫折概念和我们的结果可能对大脑网络科学家很有趣。
    The brain is a frustrated system that contains conflictual link arrangements named frustration. The frustration as a source of disorder prevents the system from settling into low-energy states and provides flexibility for brain network organization. In this research, we tried to identify the pattern of frustration formation in the brain at the levels of region, connection, canonical network, and hemisphere. We found that frustration formation has no uniform pattern. Some subcortical elements have an active role in frustration formation, despite low contributions from many cortical elements. Frustrating connections are mostly between-network connections, and triadic frustrations are mainly formed between three regions from three distinct canonical networks. We did not find any significant differences between brain hemispheres or any robust differences between the frustration formation patterns of various life-span stages. Our results may be interesting for those who study the organization of brain links and promising for those who want to manipulate brain networks.
    Brain network analysis approaches commonly ignore the signs of links. Frustration is a fascinating phenomenon referring to the conflictual arrangements of signed links. As a source of instability, it can give valuable information on altering components of a network. It can specify which brain network elements intend to drive brain network alterations. Accordingly, we tried to identify the pattern of frustration formation in the brain network, which brain network elements are more frustrated and which ones are less frustrated. We provided some maps for frustration formation in the levels of region, connection, canonical network, and hemisphere. The introduced concept of frustration and our results may be interesting for brain network scientists.
