Disentangling degree and tie strength heterogeneity in egocentric social networks

The structure of personal networks reflects how we organise and maintain social relationships. The distribution of tie strengths in personal networks is heterogeneous, with a few close, emotionally intense relationships and a larger number of weaker ties. Recent results indicate this feature is universal across communication channels. Within this general pattern, there is a substantial and persistent inter-individual variation that is also similarly distributed among channels. The reason for the observed universality is yet unclear—one possibility is that people’s traits determine their personal network features on any channel. To address this hypothesis, we need to compare an individual’s personal networks across channels, which is a non-trivial task: while we are interested in measuring the differences in tie strength heterogeneity, personal network size is also expected to vary a lot across channels. Therefore, for any measure that compares personal networks, one needs to understand the sensitivity with respect to network size. Here, we study different measures of personal network similarity and show that a recently introduced alter-preferentiality parameter and the Gini coefficient are equally suitable measures for tie strength heterogeneity, as they are fairly insensitive to differences in network size. With these measures, we show that the earlier observed individual-level persistence of personal network structure cannot be attributed to network size stability alone, but that the tie strength heterogeneity is persistent too. We also demonstrate the effectiveness of the two measures on multichannel data, where tie strength heterogeneity in personal networks is seen to moderately correlate for the same users across two communication channels (calls and text messages).

A prospective, multi-center post-marketing surveillance cohort study to monitor the safety of the recombinant zoster vaccine in Chinese adults ≥50 years of age

ABSTRACT This post-marketing surveillance study evaluated the safety of the adjuvanted recombinant zoster vaccine (RZV) in Chinese adults, given the limited country-specific safety data accumulated since the 2019 licensure of RZV in China for adults ≥ 50 years of age (YOA). This descriptive, prospective cohort study enrolled adults ≥ 50 YOA who voluntarily received RZV per routine clinical practice in six centers in China. The primary outcomes were occurrence, intensity, and causal relationship to vaccination of medically attended adverse events (MAEs) within 30 days post-any dose. The occurrence and causal relationship to RZV of serious AEs (SAEs) within 30 days post-any dose, and of SAEs and potential immune-mediated diseases (pIMDs) from dose 1 until 12 months post-last dose were secondary outcomes. The exposed set included 3,300 adults (mean age [standard deviation]: 61.2 [7.4] years; 67.1% female), of whom 3,175 completed the study. Fifty-six MAEs were recorded in 42 (1.3%, 95% confidence interval [CI]: 0.9–1.7%) participants; ≥1 grade 3 MAE was reported in six (0.2%, 0.1–0.4%) participants; 15 MAEs (in nine [0.3%, 0.1–0.5%] participants) were considered RZV-related. Within 30 days post-any dose, 12 SAEs were reported in 10 (0.3%, 0.1–0.6%) participants, while 29 SAEs in 22 (0.7%, 0.4–1.0%) participants were reported from post-dose 1 until 12 months post-last dose. The three reported fatal SAEs were not considered RZV-related. Three of the total seven pIMDs were considered RZV-related. The observed descriptive patterns of MAEs, SAEs, and pIMDs did not indicate safety concerns following RZV administration among Chinese adults ≥ 50 YOA.

Physicochemical properties of acid sulphate soil profoundly influence the composition of rhizobacterial community of rice (Oryza sativa L.)

The soils of kari lands of Kuttanad, the ‘Rice bowl’ of Kerala, India are characterized as acid sulphate as they comprise of pyrite deposits. Productivity in these soils is at stake due to several constraints like high acidity and salinity, metal toxicity, nutrient unavailability, redox fluctuations, besides seasonal flooding. Sustainable management of acid sulphate soil is a critical priority to improve the rice output from these areas. Such soils would harbor unique innate microbial communities with definite abilities which could be exploited further for their sustainable amelioration. Development of inoculant technology with soil and crop specific beneficial microbial agents is expected to boost the production potential of kari soils. However, the soil parameters would impose a great influence on the rhizobacterial community development in these geologically distinct soils. We studied the rhizobacterial communities (at the family level), associated with rice grown in five acid sulphate (Purakkad, Vaikom, Ambalappuzha, Thakazhi and Kallara) as well as one non-acid sulphate (Muhamma) soil series of geographically unique Kuttanad region. We also examined the effects of soil physicochemical attributes on shaping the rhizosphere bacterial community assemblage. The soil physicochemical attributes were analyzed using standard procedures and correlations existing amongst them were also determined. A metagenomic approach was adopted to study the rhizobacterial communities (family level) and were correlated with soil parameters using canonical correspondence analysis (CCA). Compared to other acid sulphate regions, Thakazhi and Kallara soils indicated higher electrical conductivity, available nitrogen, potassium, organic carbon, aluminium as well as iron and lowest pH and available phosphorus. Intense significant relationships were exhibited amongst the acid sulphate properties and soil nutrient contents. The taxa summary after the Illumina MiSeq sequencing revealed the abundant rhizobacterial families in the soil samples as Anaerolineaceae, Ktedonobacteriaceae, Acidothermaceae, Acidimicrobiaceae, Clostridiaceae, Nocardioidaceae, Xanthobacteraceae, Methanobacteriaceae, Sphingomonadaceae and Peptostreptococcaceae. Acidothermaceae (14%) and Acidimicrobiaceae (12%) were found abundant exclusively in highly acid sulphate soil samples. Moreover, only a few shared taxa were observed between the soil samples, which denoted the uniqueness of each sample in terms of rhizobacterial communities. The shared taxa between highly acidic sampling areas include members of Acidothermaceae, Ktedonobacteraceae, Acidimicrobiaceae, Micrococcaceae, Stellaceae and Anaerolineaceae. CCA showed that pH, EC and Al content were the soil properties governing the bacterial assembly in the rhizosphere of actively tillering rice grown in acid sulphate soil followed by P and K. The data generated in the present study are considered to be of use in developing consortia of kari soil specific rice rhizosphere microbial agents which could be used as inoculants in future.

A computational signature of self-other mergence in Borderline Personality Disorder.

A tendency to merge mental representations of self and other is thought to underpin the intense and unstable relationships that feature in Borderline Personality Disorder (BPD). However, clinical theories of BPD do not specify, in computational terms, how the perspectives of self and other might become confused. To address this question, we used a probabilistic false belief task (p-FBT) to examine how individuals with BPD (N = 38) and matched controls from the general population (N = 74) selectively assigned beliefs to self or other. The p-FBT requires participants to track a gradually changing quantity, whilst also predicting another person's belief about that quantity. We found that BPD participants showed less selectivity in belief assignment compared with controls (Cohen's d = 0.64). Behaviourally, participants with BPD tended to predict that others' beliefs resembled their own. Modelling analysis revealed that BPD participants were prone to generalise their own learning signals to others. Furthermore, this generalising tendency correlated with BPD symptomatology across participants, even when controlling for demographic factors and affective psychopathology. Our results support a computational account of self-other mergence, based on a generalisation of learning across agents. Self-other generalisation in learning purports to explain key clinical features of BPD, and suggests a potential transdiagnostic marker of mentalising capability.

Opinion Leaders in Organizational Change Processes: Insights from a Large-Scale Quantitative Survey to Identify, Characterize, and Classify Influential Employees within a Multinational Corporation

ABSTRACT The successful implementation of change processes requires efficient and effective communication. While previous research has explored various aspects of change communication, the role of opinion leaders – individuals who are more influential than others within their networks – has been largely overlooked. These opinion leaders could play a key role in driving the successful implementation of organizational change. This study aims to investigate the characteristics and potential existence of distinct types of opinion leaders within the context of an organizational change process. We conducted a quantitative online survey (n = 4,114) in a multinational corporation undergoing a significant change initiative. The findings reveal that opinion leadership is influenced by several factors: opinion leaders often hold leadership positions, possess strong personality traits, and maintain cross-hierarchical and cross-functional networks characterized by intense relationships. They also demonstrate high expertise related to the change process and exhibit strong commitment and positive attitudes towards it. Additionally, the study identified 300 opinion leaders and, through cluster analysis, categorized them into four types: ‘The Expert Leader,’ ‘The Emerging Opinion Leader,’ ‘The Cross-Functional Connector,’ and ‘The Department Influencer.’ These types vary in their network sizes, structures, and experiences. MAD statement In a rapidly evolving world, effective change communication is essential for building resilient and forward-thinking organizations. While research has acknowledged the pivotal role of communication in driving change, the significant influence of opinion leaders in this process has received limited attention. These individuals can be key to ensuring that organizational transformations are not only successful but also inclusive and sustainable in their impact. By understanding how to identify and engage opinion leaders in substantial change initiatives, organizations can develop more effective communication strategies that foster innovation, adaptability, and long-term success, ultimately contributing to more equitable, responsible, and successful organizational transformations.

Unveiling Relationship Between Specific Domain, Intensity, and Dose of Physical Activity and Biological Age: A Cross-Sectional Study.

Existing studies have separately explored the association between specific intensity and domain of physical activity (PA) and biological age (BA), potentially impeding more precise guide. We used data of 5216 middle-aged and older adults aged 45 and over to explore and compare the relationship of different domains, intensities, and doses of PA and BA. Transport-related walking and leisure-time moderate-intensity PA (MPA) were significantly associated with younger BA, rather than other intensity of work-related PA. There were U-shaped dose-response relationships between transport-related BA or leisure-time MPA and BA. In subgroup analyses for older adults, all intensities of PA were significantly associated with decreased BA. These findings highlighted the importance of considering the domain, intensity, and dose of PA in designing effective age-delaying interventions.

Do Commercial Ties Influence ESG Ratings? Evidence from Moody's and S&P

ABSTRACTWe provide the first evidence that conflicts of interest arising from commercial ties lead to bias in environmental, social, and governance (ESG) ratings. Using the acquisitions of Vigeo Eiris and RobecoSAM by Moody's and S&P as shocks to the commercial ties between ESG rating agencies and their rated firms, we show that, after their acquisitions by the credit rating agencies (CRAs), ESG rating agencies issue higher ratings to existing paying clients of the CRAs. This effect is greater for firms that have more intensive business relationships with the CRAs, but weaker for firms with more transparent ESG disclosures or higher long‐term institutional ownership. The upwardly biased ESG ratings help client firms issue more green bonds and enable the CRAs to maintain credit rating business. Finally, the upwardly biased ESG ratings are less informative of future ESG news. Overall, the business incentives of rating providers appear to engender ESG rating bias.

Converging profile relationships for offshore wind speed and turbulence intensity

Abstract. This paper reduces uncertainty in the quantification of offshore wind speed and turbulence intensity. A range of industry standard relationships, including those from International Electrotechnical Commission (IEC) and International Organization for Standardization (ISO), are compared with an extensive set of met mast data collected offshore northwestern Europe over recent decades. Analysis initially focused on over 1000 independent storm peak events identified within the 10 min mean wind speed data. Time series and coherent vertical profiles were subjected to detailed scrutiny and analysis, considering wind speeds at various averaging periods, turbulence intensity and gust factors. Most peak events were associated with neutral atmospheric conditions, so they were well represented by the ISO Frøya profile, with a shear close to the IEC power law exponent of α= 0.11. A new pragmatic approximation of atmospheric stability in terms of relative shear is outlined, bringing together key elements of the IEC and ISO standards. New empirical relationships to quantify offshore wind ambient turbulence intensity are described. A simple generalised form of gust factor relationship is adopted, with a coefficient that varies with averaging period. Distinct recommendations are made for estimating peak 10 min mean winds from peaks in 1 or 3 h mean winds. Finally, a simplified workflow for the estimation of extreme offshore winds is used to show how IEC and ISO relationships can be effectively combined.

The examining the relationship of telework intensity and work-family conflict: Work autonomy as moderator

Purpose: While telework offers many advantages during the COVID-19 pandemic, it can also increase pressure and lead to greater work-family conflict for workers. Work autonomy plays a key role in moderating the relationships of telework and work-family conflict. The purpose of this study was to examine the influence of work autonomy on the relationship between telework intensity and work-family conflict. Method: This study involved participants from various e-commerce companies in Indonesia with a total of 86 workers who meet the criteria of working telework, married and having children under 18 years. The data of this study were analysed using hierarchical regression analysis that to assess the moderator role of work autonomy in the relationship between the telework intensity and work-family conflict. Result: The study found telework increases work-family conflict, moderated by work autonomy, with higher autonomy reducing conflict. Gender and period of work also known to influence work-family conflict. Conclusion: Based on the findings of this research, companies can help their workers to manage work-family conflict by giving more job autonomy within their telework systems.

Intensified upwelling: normalized sea surface temperature trends expose climate change in coastal areas

Abstract. Eastern boundary upwelling systems (EBUSs) provide valuable natural resources due to their high primary production. However, there is significant uncertainty in how climate change may affect the mechanisms that sustain these ecosystems in the future. Therefore, assessing the effects of climate change on EBUSs under the current global warming scenario is crucial for efficient ecosystem management. In 1990, Andrew Bakun suggested an increase in the upwelling intensity due to the rise of the ocean–land pressure gradient. Since there is a significant link between thermal gradients and offshore Ekman transport, we use sea level pressure (SLP) and deseasonalized sea surface temperature (SST) data from remote sensing to elucidate this hypothesis and validate it using in situ observations. SST is an indicator of coastal upwelling, and our long-term analysis of monthly and deseasonalized SST records shows that the seasonal and synoptic processes have minimal influence on the SST–upwelling intensity relationship. Upwelling within the same EBUS is not usually evenly distributed along coastlines, leading to upwelling in specific areas, referred to as upwelling centers. We compare the SST trends in the main upwelling centers of the four EBUSs with those in open ocean waters through a new index, αUI, designed to characterize upwelling changes in the EBUS. An a-dimensional number allows us to normalize the trends independently of the upwelling system and compare all of them. Furthermore, we have complemented the SST index with sea level pressure gradient data. This new index (supported by SLP gradient trends) indicates intensification in all the EBUSs, revealing a coherent pattern within EBUSs in the same ocean (i.e., Canarian and Benguela or Californian and Humboldt upwelling systems).

Texture Analysis in Volumetric Imaging for Dentomaxillofacial Radiology: Transforming Diagnostic Approaches and Future Directions.

This narrative review explores texture analysis as a valuable technique in dentomaxillofacial diagnosis, providing an advanced method for quantification and characterization of different image modalities. The traditional imaging techniques rely primarily on visual assessment, which may overlook subtle variations in tissue structure. In contrast, texture analysis uses sophisticated algorithms to extract quantitative information from imaging data, thus offering deeper insights into the spatial distribution and relationships of pixel intensities. This process identifies unique "texture signatures", serving as markers for accurately characterizing tissue changes or pathological processes. The synergy between texture analysis and radiomics allows radiologists to transcend traditional size-based or semantic descriptors, offering a comprehensive understanding of imaging data. This method enhances diagnostic accuracy, particularly for the assessment of oral and maxillofacial pathologies. The integration of texture analysis with radiomics expands the potential for precise tissue characterization by moving beyond the limitations of human eye evaluations. This article reviews the current trends and methodologies in texture analysis within the field of dentomaxillofacial imaging, highlights its practical applications, and discusses future directions for research and dental clinical practice.

Relationship of chronic low back pain intensity with functional activity, stress and quality of life in working-age adults

Background. Low back pain (LBP) is a global problem in the modern world. A detailed study of the relationship between pain intensity and the indicators with which it may be associated will allow optimising approaches to the treatment and rehabilitation of patients with chronic LBP. The purpose was to eva­luate the relationship between the intensity of chronic LBP and indicators of functional activity, stress and quality of life in subjects of working age. Materials and methods. A survey was conducted among 159 persons aged 18-65 years with LBP lasting more than 3 months. Using a Google-form, the participants were given a questionnaire that included socio-demographic, anthropometric characteristics, lifestyle data, bad habits, physical activity (PhA) and stress levels, quality of life, and impairment. The intensity of pain was measured at the first visit to a PhRM doctor using a visual analogue scale (VAS). Results. The study involved 159 patients, 65.7 % women and 34.3 % men, with a mean VAS pain intensity of 46.5 ± 18.6 mm. A weak positive correlation was found between pain intensity and age (r = 0.30, p < 0.001), but no significant relationship was found between pain intensity and anthropometric parameters. Subjects who smoke, have insufficient PhA and sleep disturbance had higher pain intensity scores (57.6 ± 15.2 mm (p = 0.04), 49.0 ± 18.8 mm (p = 0.12), 49.7 ± 19.9 mm (p = 0.002), respectively). Sitting time more than 6 hours had significant associations with pain intensity (p < 0.001). A weak positive correlation was found between pain intensity on the VAS scale and stress le­vel (r = 0.24, p = 0.002), a moderate positive correlation between pain intensity and impairment (r = 0.36, p < 0.001) and a mo­derate negative correlation between quality of life and pain intensity. ­Conclusions. There was a significant association between pain intensity and age, smoking, sleep disturbance, sedentary work for more than 6 hours, higher stress levels, impaired functioning and lower quality of life.

Synthesis, in vitro and in vivo biological evaluation of novel dual compounds targeting both acetylcholinesterase and serotonergic 5-HT4 receptors with potential interest in the treatment of Alzheimer's disease

In this work, we exemplified the “copride” family of drug candidates able to both inhibit acetylcholinesterase and to activate 5-HT4 receptors, with anti-amnesiant and promnesiant activities in mice. Twenty-one analogs of donecopride, the first-in class representative of the series, were synthesized exploring the influence on the biological activities of the substituents (methoxy, amine and chlorine) carried by its phenyl ring. This work was the support of an intensive structure-activity relationship study and allowed to obtain some interesting derivatives of donecopride. In this respect, the replacement of the methoxy group of the latter with a deuterated one led to deudonecopride. On the other hand, the replacement of the chlorine atom of donecopride by various halogen atoms was of particular interest, among which fluorine led to a potent analog, we called flucopride. The latter exhibited promising in vitro activities associated to excellent drugability parameters. Flucopride was consequently involved in in vivo studies such as a scopolamine-induced deficit model of working memory and in a novel object recognition test. Through these evaluations, flucopride demonstrated both its antiamnesiant and promnesiant capacities, which could make it a potential preclinical drug candidate for the treatment of Alzheimer's disease.

Association of Short-term Pain and Chronic Pain Intensity With Cardiometabolic Multimorbidity Progression: A Multistate Markov Model Analysis.

The impact of pain intensity on the progression trajectories of cardiometabolic multimorbidity (CMM) is not well understood. We attempted to dissect the relationship of short-term pain (STP) and chronic pain intensity with the temporal progression of CMM. We conducted a prospective cohort study based on the UK Biobank participants. Incident cases of cardiometabolic diseases (CMDs) were identified based on self-reported information and multiple health-related records in the UK Biobank. CMM was defined as the occurrence of at least 2 CMDs, including heart failure (HF), ischemic heart disease (IHD), stroke, and type 2 diabetes (T2D). The pain intensity was categorized into 5 levels based on pain duration and the number of sites involved, including chronic widespread pain (CWSP), chronic multilocation pain (CMLP), chronic single-location pain (CSLP), STP, and free-of-pain (FOP). Multistate models were used to assess the impact of pain intensity on the CMM trajectories from enrollment to initial cardiometabolic disease (ICMD), subsequently to CMM, and ultimately to death. A total of 429,145 participants were included. Over the course of a 12.8-year median follow-up, 13.1% (56,137/429,145) developed ICMD, 19.6% (10,979/56,137) further progressed to CMM, and a total of 5.3% (22,775/429,145) died. Compared with FOP, CMLP (hazard ratio [HR], 1.11; 95% confidence interval [CI], 1.06-1.17) and CWSP (HR, 1.26; 95% CI, 1.13-1.42) elevated the risk of transitioning from ICMD to CMM. STP (HR, 0.89; 95% CI, 0.82-0.96), CSLP (HR, 0.88; 95% CI, 0.82-0.95), and CMLP (HR, 0.87; 95% CI, 0.81-0.93) lowered the risk of transition from ICMD to mortality, and STP also reduced the risk of transition from enrollment to mortality (HR, 0.94; 95% CI, 0.89-0.98). The results of disease-specific transitions revealed that the influence of pain intensity varied across transitional stages. Specifically, CMLP and CWSP heightened the risk of conversion from T2D or IHD to CMM, whereas only CWSP substantially elevated the transition risk from HF to CMM. Our results highlighted reductions in chronic pain may mitigate both the onset and progression of CMM, potentially having an important impact on future revisions of cardiometabolic and pain-related guidelines.

High Body Mass Index Disrupts the Homeostatic Effects of Pain Inhibitory Control in the Symptomatology of Patients With Fibromyalgia

This study examines the influence of body mass index (BMI) on the relationship between quantitative sensory testing measures and clinical characteristics in fibromyalgia syndrome (FMS). Utilizing BMI as a categorical covariate (≥25 or ≥30 kg/m²) in associations between quantitative sensory testing metrics (pain-60, conditioned pain modulation, and temporal summation of pain [TSP]) and FMS clinical features, we explored BMI's role as both a confounder (change-in-estimate criterion—change equal or higher than 10%) and effect modifier (interaction term). Significant interactions revealed overweight/obese BMI as a modifier in the relationship between conditioned pain modification and both depression and symptom impact, with a homeostatic relationship between better clinical profile and pain inhibitory response observed solely in the normal-weight group. Similar results were found for pain-60 and depression. Additionally, BMI ≥30 kg/m² modified TSP's effect on pain, demonstrating lower pain with increased TSP, exclusively in the nonobese group. This study highlights the significant role of BMI in moderating the relationships of important pain inhibitory control processes and pain intensity, depression, and the overall impact of FMS symptoms. Our results suggest that high BMI states disrupt the homeostatic effects of pain inhibition, reducing its salutogenic response in FMS participants. We discuss the mechanistic and therapeutic implications of targeting BMI in FMS clinical trials and the potential impact of this important relationship. PerspectiveThis investigation highlights the disruptive influence of high BMI on pain inhibitory control in fibromyalgia, unbalancing clinical symptoms such as pain and depression. It underscores the necessity of integrating BMI considerations into therapeutic approaches to enhance pain management and patient outcomes.

Relationship between Climacteric Symptom Intensity, Physical Activity Level, Spine Mobility, Balance, and Quality of Life in Women

Objective: The climacteric period contains more than 1/3 of a woman's life and causes various symptoms stemming from physiological and hormonal changes. Our study investigated the relationship of climacteric symptom intensity with physical activity level, spine mobility, balance, and quality of life. Methods: 64 women (49,5 ± 4,24 years) in the climacteric period were included in the study. Climacteric symptom severity was assessed with the Blatt-Kupperman Index, physical activity levels with the International Physical Activity Questionnaire, quality of life with the Menopause-Specific Quality of Life Questionnaire, and balance with the single-leg stance test. The correlations between the variables were analyzed with the Pearson and Spearman Correlation analysis. Results: Of the participants, 15.6% had minor severe symptoms, 59.4% had mild severe symptoms, 18.8% had moderately severe symptoms and 6.3% had severe climacteric symptoms. The climacteric duration was negatively correlated to spinal mobility measures (r= -0.26 - -0.30) and the quality of life (r= 0.26) (p

The SME R&D intensity and product innovation relationship: the mediating role of quality management in the context of a developing country

SMEs engage in product innovation despite their inherent resource constraints, lack of financial slack, and the under‐development of competitively viable strategic configurations around the globe. While progress has been made in identifying the antecedents and capabilities attributed to successful innovation outcomes and the performance of these firms, there remain disparate and often paradoxical observations on the factors that affect SME innovation performance across geographies (i.e. developed vs developing countries) and operational contexts (R&D intensity and quality management practices). This study collected data from 241 resource‐constrained small and medium‐sized enterprises (SMEs) in a developing country (Ghana) to contribute to this debate. The results of structural equation modeling show that quality management mediates the relationship between R&D intensity and product innovation. The results also reveal the effects of knowledge integration and financial slack on the relationship between R&D intensity and product innovation, with a high level of knowledge integration enhancing the effect but a high financial slack hinders it. This study sheds light on a broader range of contextual and financial variables when seeking contingencies of SME product innovation performance within theory and practice.

The Relationship of Pain Intensity, Perceived Injustice, and Pain Catastrophizing to Heart Rate Variability In Naturally Occurring Acute Pain.

Behavioral factors of pain catastrophizing and perceived injustice are associated with pain intensity in chronic pain. Diminished heart rate variability (HRV) is also strongly associated with chronic pain. These factors have been less explored earlier in the pain experience and it is unclear whether they play a role in the transition from acute to chronic pain. The aim of this study was to determine the relationship between pain catastrophizing, perceived injustice, pain intensity, and HRV in naturally occurring acute pain. Ninety-seven patients were recruited from local outpatient physical therapy clinics. Seated HRV was captured on 94 patients via Polar chest strap while patients were taking a survey via iPad. In addition to sociodemographic data, the survey included the Pain Catastrophizing Scale (PCS), Injustice Experience Questionnaire (IEQ), and Numeric Pain Rating Scale (NPRS). The natural log of high-frequency power (lnHFP) HRV was used in the statistical analysis. Multiple linear regression modeling revealed that lower pain catastrophizing, higher perceived injustice, and lower pain intensity were associated with lower HRV, and accounted for 11.4% of the variance in HRV. While greater chronic pain intensity is associated with lower HRV, the relationship is reversed in the setting of acute pain. These findings highlight the need to better understand the unique factors that contribute to lower HRV in the acute phase.

Information asymmetry, policy shocks, and international equity investment: Evidence from the anti‐corruption campaign in China

AbstractInformation plays a critical role in financial transactions and markets, especially in international investment where foreign investors are at an informational disadvantage relative to domestic investors. Prior studies show a positive reaction of the Chinese capital market to China's anti‐corruption campaign, which is also consistent with improved performance of Chinese listed firms following the campaign. We document a contrasting reaction of less‐informed foreign investors. Exploiting staggered anti‐corruption investigations across provinces as plausibly exogenous shocks, we find that foreign institutional investors increase their equity investments in Chinese listed firms headquartered in affected provinces following the anti‐corruption campaign; foreign individual investors, by contrast, reduce their equity investments after the campaign, which is driven by those with non‐Chinese ethnicity. Further analyses show that the increased equity investments of foreign investors stem primarily from those residing in jurisdictions sharing a similar cultural tradition with China. Our study has significant implications for foreign investors in the context of the increasingly intense relationship between China and the West.

Interlibrary relationship development between Baltic republics

In this article, the main periods of the development of interlibrary relationships between Latvia, Lithuania, and Estonia are characterized. It is suggested that official interlibrary relationships began in 1930 with the organization of the first conference for librarians. Collaboration between the largest scientific libraries of the Baltic republics emerged in the 1950s. However, during the years 1945-1957, the relationships could be characterized as spontaneous, unplanned, and covering only a few areas of library work. Since the 1960s, these relationships became more intensive, with new forms of collaboration being applied. In the 1960s-1970s, traditional forms of interaction between libraries of the same type were implemented in practice. The most intensive relationships were developed between technical libraries. Although recently a unified coordination of this relationship does not exist, which is why the potential for collaboration is only partially utilized, the interlibrary commissions and methodological centers are the main institutions for the further development of interlibrary coordination.
