Purpose: To present a method for systematically mapping diversity of publication patterns at the author level in the social sciences and humanities in terms of publication type, publication language and co-authorship.Design/methodology/approach: In a follow-up to the hard partitioning clustering by Verleysen and Weeren in 2016, we now propose the complementary use of fuzzy cluster analysis, making use of a membership coefficient to study gradual differences between publication styles among authors within a scholarly discipline. The analysis of the probability density function of the membership coefficient allows to assess the distribution of publication styles within and between disciplines.Findings: As an illustration we analyze 1,828 productive authors affiliated in Flanders, Belgium. Whereas a hard partitioning previously identified two broad publication styles, an international one vs. a domestic one, fuzzy analysis now shows gradual differences among authors. Internal diversity also varies across disciplines and can be explained by researchers’ specialization and dissemination strategies.Research limitations: The dataset used is limited to one country for the years 2000–2011; a cognitive classification of authors may yield a different result from the affiliation-based classification used here.Practical implications: Our method is applicable to other bibliometric and research evaluation contexts, especially for the social sciences and humanities in non-Anglophone countries.Originality/value: The method proposed is a novel application of cluster analysis to the field of bibliometrics. Applied to publication patterns at the author level in the social sciences and humanities, for the first time it systematically documents intra-disciplinary diversity. 展开更多

Adolescence is a crucial time period with especial vulnerability for development of mental health problems.Growing interest is focusing on the determinants of positive mental health in order to find the key concepts that could be influenced in the promotion of mental well-being of adolescents.In this study we aim to explore the relations between self-esteem,character strengths and experience of social inclusion as determinants of adolescents’positive mental health controlled for selected sociodemographic background factors.The study population(n=195)consisted of comprehensive school students who filled in an electronic questionnaire of adolescent’s mental well-being in Fall 2019.The questionnaire included measures of Warwick-Edinburgh Mental Well-being Scale(WEMWBS),VIA Youth-measure 96,Rosenberg Self-Esteem Scale and Experience of Social Inclusion Scale.The methods included group comparisons and General Linear Model computed by SPSS 24.0.The strongest association was found between positive mental health and self-esteem(β=0.789,p<0.001),followed by character strengths of hope and kindness and experience of social inclusion.Interestingly,family’s socioeconomic factors did not associate significantly with positive mental health in the final statistical model.In terms of our results,it seems that self-esteem,character strengths and experience of social inclusion might have stronger association with adolescents’mental well-being than family’s socioeconomic determinants.Therefore,it should be discussed whether psychological determinants overcome the individual effect of poor socioeconomic status as factors that influence positive mental health.Further studies are needed to establish these results more firmly. 展开更多

Background: To facilitate effective program designs aimed at assisting youth avoid unnecessary negative reproductive health outcomes, there is need to understand determinants of condom use among adolescents. Objectives: To determine demographic, socioeconomic and psychosocial factors associated with adolescent condom use in Botswana. Methods: Logistic regression models were employed to analyse a weighted sample of 221 adolescents aged 15 to 19 years from the 2012 Botswana AIDS Impact Survey who had a sexual relationship during the 12 months preceding the survey. Results: A majority of adolescents were current and consistent condom users (81% and 72% respectively). Both current and consistent condom use were positively associated with secondary or higher education, unemployed, high perception of severity of HIV to health and high self-efficacy perception. However, being female, non-Christian, having medium or comprehensive HIV/AIDS related knowledge and high perceived personal risk to HIV infection were negatively associated with both outcomes. Although being 18 to 19 years, having multiple sexual partners and high perception of condom attributes were positively associated with current condom use, they were negatively associated with consistent use. Conclusions: The study showed that in addition to demographic and socioeconomic factors, psychosocial factors are important predictors for condom use among adolescents. 展开更多

Urban forest parks deliver a wide spectrum of ecosystem services that support biodiversity,climate regulation,and public well-being;however,their perceived value among local visitors remains underexplored in Southeast Asia.This study investigates visitor perceptions and economic valuation of ecosystem services at Mount Pulai Forest Eco Park in Johor,Malaysia.Grounded in the Total Economic Value(TEV)framework and ecosystem service theory,the research employed a structured on-site survey of 392 visitors and applied the Contingent Valuation Method(CVM)to assess awareness,appreciation,and willingness-to-pay(WTP)for forest conservation.Findings revealed that visitors highly valued regulating services,such as air purification and flood mitigation(mean≈4.3/5),and supporting services,like biodiversity(mean≈4.2/5),while provisioning services were rated lower(mean≈2.8/5).Despite limited familiarity with ecological terminology,only 33%understood the term“ecosystem services”.In contrast,a substantial majority(79.1%)expressed WTP for conservation efforts,proposing an average annual contribution of MYR 51.32.Additionally,65%of respondents supported an entry fee model,suggesting a mean payment of MYR 3.07 per visit.These results underscore the economic and non-economic value that urban residents assign to forest benefits,offering new insights into conservation finance and public engagement.The study’s innovation lies in its integration of ecosystem perception with economic valuation in an urban forest setting,providing a replicable framework for sustainable park management across Southeast Asia. 展开更多

This study offers valuable insights into the relationship between metro ridership patterns and the spatial transformations around Delhi Metro stations,underscoring the role of mass transit infrastructure in shaping urban land use and ecosystem landscapes.The primary objective is to assess how high-ridership metro stations can positively influence urban development,particularly regarding socio-economic and ecological dimensions.Integrating primary survey data with ridership statistics from the Delhi Metro Rail Corporation(DMRC),the research identifies key interchange stations,such as Kashmere Gate and Rajiv Chowk,which exhibit substantial passenger volumes.Utilising GIS-based spatial analysis and remote sensing techniques,land use changes within a 500-meter buffer zone around these stations are considered,focusing on built-up areas,green cover,and open space availability.Time-series satellite imagery generates comparative maps illustrating land use changes pre-and post-introduction of metro services.The analysis reveals that high-ridership stations are linked to significant commercial densification,particularly near Rajiv Chowk,with a p-value of 0.172.Conversely,peripheral stations like Dwarka Sector 21 indicate residential growth trends,with a p-value of 0.087 for residential areas.Importantly,two land use categories—Green Space(t=-2.33,p=0.045)and Open Space(t=3.57,p=0.006)—show statistically significant reductions,highlighting the ecological impacts of metro infrastructure.The findings suggest that metro systems can promote commercial clustering in urban centres while fostering residential growth in surrounding areas.Overall,the study highlights the potential of metro systems to enhance accessibility,reshape urban ecosystems,and encourage the development of compact urban forms.The implications for urban planning advocate for transit-oriented development(TOD)as a strategic approach to manage growth,minimise sprawl,and ensure sustainable and inclusive development. 展开更多

Non-communicable diseases (NCDs) are on the rise worldwide and in developing countries like Botswana. Unhealthy eating habits and lack of proper nutrition knowledge cause non-communicable diseases and affect adolescents. It is in adolescence that eating habits are formed that persist till adulthood. Lifestyle interventions are needed to curb NCDs in adolescents. This paper reports the findings of a study that aimed to validate a lifestyle intervention program and its effect on food intake, physical activity, and nutrition knowledge. It was a clustered randomized control trial study conducted in four (4) junior secondary schools. There were 46 participants, 21 in the control and 25 in the intervention arm, who were blindly assigned to each arm by a statistician. Information and skills on nutrition were imparted using the Information, Motivation, and Behavioral Skills model. The program was implemented for eight (8) weeks hourly after school. A questionnaire was used to collect data pre- and post-intervention. Number, proportion, percentage, and independent t-test (mean and SD or median and IQR, p-value) were calculated using numerical and categorical data. The findings showed that the lifestyle intervention was valid, and there was a slight decrease in the intake of sweets among participants in both trial arms (p = 0.066). There was no significant difference in terms of food intake. Only a small number of participants still ate a few fruits, and there was no change in vegetable intake in both trial arms (p = 0.641). There was no change in the intake of fried foods in both trail arms (p = 0.402). Regarding nutrition knowledge, there was a slight significant difference of p = 0.079 between the trial arms. Though the effect of the lifestyle intervention program was not statistically significant, the results are promising, especially if the duration could be increased to a longer period and a larger sample size included. 展开更多

There is a wide recognition that encompassing an obligation of good faith in every commercial contract is one of the most important advances in contract law in the twentieth century^([1]).Despite the fact that this concept has been incorporated in the vast majority of national legal systems,its precise scope and application may vary from one to another,depending on the commercial traditions and customs of each legal system^([2]).The fact that good faith has been treated differently in different national legal systems has also been reflected on the international level through its inclusion in international legal instruments,one of which is the United Nations Convention on Contracts for the International Sale of Goods(hereafter CISG).In this article,the legislative history of the CISG will be closely examined with the purpose of finding out how a compromise was reached between the common law countries,which expressly objected to the imposition of a duty of good faith,and the civil law countries,which explicitly endorse its incorporation.A logical result flowing from this historical examination,as will be submitted,is that the conceptual ambiguity of good faith is the underlying reasoning behind their fundamentally different attitudes towards the incorporation of this notion in the international commercial context. 展开更多

This article analyzes the predictability of market betas concerning cryptocurrency assets and evaluates the efficiency of beta-hedged,market-neutral portfolios.We forecast 1-year-ahead market betas using various estimating methods,including ordinary least squares(OLS)and Vasicek’s Bayesian shrinkage estimator,and assess their impact on portfolio variance reduction across cryptomarket indices.Our findings indicate that while standard OLS betas explain significantly less of the variation in future betas for cryptoassets compared to US stocks,slope winsorization and Bayesian shrinkage improve prediction accuracy.The results suggest that beta-hedged portfolios reduce variance for approximately 17%of the universe,with the Broad Digital Market Index demonstrating the best hedging efficiency.These findings underscore the significant challenges of developing effective hedging strategies in the cryptocurrency market,emphasizing the importance of idiosyncratic risk in crypto returns and the need for appropriate market index representation. 展开更多

Amidst the unique challenges faced by rural educators is their sense of decent work influenced by levels of social support,career self-efficacy,and marginalization.To investigate these relationships,we surveyed 435 rural school teachers(females=69.32%,mean years teaching experience=13.6,SD=7.7 years).The Structural Equation Modeling results indicated that social support positively predicts teachers’perceptions of decent work.Career self-efficacy mediated the relationship between social support and a higher sense of decent work,while marginalization mediated the relationship such that lower social support predicted lower perceptions of decent work.Career self-efficacy and marginalization also had a sequential mediation relationship:higher social support enhanced career self-efficacy,which in turn reduced marginalization experiences,ultimately improving teachers’perceptions of decent work.These findings align with the predictions of Social Cognitive Career Theory and the Psychology of Working Theory,demonstrating that environmental supports enhance personal psychological resources,reduce marginalization risks,and promote positive work-related outcomes.The study findings highlight the necessity for education departments to improve rural teachers’perceptions of decent work by providing social support to foster positive work experiences for teachers at high risk for marginalization and diminished career self-efficacy. 展开更多

Climate variability significantly impacts agricultural water resources,particularly in regions like Vietnam's Plain of Reeds that heavily utilize rain-fed conditions.This study employs the FAO-AquaCrop model to estimate current and future irrigation water needs for rice cultivation in this critical subregion,aiming to identify optimal sowing schedules(OSS)that enhance rainwater utilization and reduce irrigation dependency.The model was driven by current climate data and future projections(2041-2070 and 2071-2099)derived from downscaled Global Circulation Models under RCP4.5 and RCP8.5 scenarios.The AquaCrop model demonstrated robust performance during validation and calibration,with d-values(0.82-0.93)and R²values(0.85-0.92)indicating strong predictive accuracy for rice yield.Simulation results for efficient irrigation water potential(IWP)under RCP4.5 revealed that strategic shifts in sowing dates can substantially alter water requirements;for instance,advancing the winter-spring sowing to December 5th decreased IWP by 15.6%in the 2041-2070 period,while delaying summer-autumn crop sowing to April 20th increased IWP by 48.6%due to greater reliance on irrigation as rainfall patterns shift.Similar dynamic responses were observed for the 2071-2099 period and for autumn-winter crops.These findings underscore that AquaCrop modeling can effectively predict future irrigation needs and that adjusting cultivation calendars presents a viable,low-cost adaptation strategy.This approach allows farmers in the Plain of Reeds to optimize rainwater use,thereby reducing dependency on supplementary irrigation and mitigating the adverse impacts of climate variability,contributing to more sustainable agricultural water management. 展开更多

Urban flooding in low-lying coastal regions(LCRs)is intensifying due to climate change and sea-level rise;however,the complex interplay of hydrological,climatic,and anthropogenic drivers remains poorly understood.This study investigates the specific meteo-hydrological factors linking climate-induced changes and human activities to the urban flooding event in My Tho City,a vulnerable coastal city in Vietnam's Tien Giang Province,from February 9 to 12,2024.Analyzing historical meteo-hydrological data(rainfall,monsoon winds,river discharge,and water levels),we examined the contributing factors.Our findings reveal that the flooding was predominantly driven by the combination of high astronomical tidal levels and significant water surges.These surges were amplified by northeast monsoon circulation.This situation was compounded by critically low Mekong River discharge during the dry season,which enhanced the inland penetration of tidal effects.Rainfall during the period was minimal and did not contribute significantly.We utilized a filtering technique to differentiate between astronomical tides and non-tidal surges in the water level data.These results provide empirical evidence demonstrating that climate-driven sea-level influences(manifesting as high tides and surges)and anthropogenic alterations to river flow governed the urban flooding dynamics.The study underscores the urgent need for integrated adaptation solutions addressing the complex land-ocean interactions, particularly in the context ofclimate change and relative sea-level rise. 展开更多

Purpose:Despite the global shutdown of universities and research laboratories in 2020 due to the COVID-19 pandemic,a significant and unexpected increase in scientific production was observed during 2020 and especially in 2021(Rousseau et al.,2023).A plausible explanation is that researchers took advantage of the lockdown period to write and develop pre-existing ideas.But what happened once that stockpile of ideas was exhausted?Design/methodology/approach:This study aims to address that question by analyzing the scientific output of fourteen highly productive countries using data from three databases:WoS,Scopus,and OpenAlex.Findings:Our analysis shows that,following the production peak in 2021,there was a general decline over the next two years(2022 and 2023)across most Western countries,including Japan and Brazil.However,this trend was not observed in China or India,which have maintained sustained growth since 2021.Russia,by contrast,has shown a continuous decline since 2021,likely related to its involvement in armed conflicts.Notably,this pattern of decline persists even when excluding the broad category of Life Sciences and Biomedicine.Research limitation:The observed phenomenon cannot be fully explained.A broader understanding would require the wide distribution of a questionnaire among researchers and institutions.Practical implications:This study provides insight into how the scientific system responded through its publication output to the temporary suspension of research institutions’activities during the COVID-19 lockdown.Originality/value:Our analysis contributes to understanding the unusual trends in research publications due to the pandemic’s influence.It can be seen as a discussion of a natural experiment in the science of science. 展开更多

Habit formation is essential for environmental preservation and sustainability as it promotes consistent,long-term engagement in pro-environmental behaviors.Habitual pro-environmental behaviors contribute to the establishment of social norms,encouraging communities to adopt sustainable lifestyles collectively.As more people integrate environmentally conscious practices into their daily routines,the broader cultural shift toward sustainability becomes more pronounced.This paper explored the experiences of environmental advocates of sustainability,emphasizing habit formation as a fundamental driver of long-term ecological responsibility.Environmental advocates(n=20)from the Visayas,Philippines,were purposively sampled for interviews.Participants expressed a deep personal commitment to sustainability as a lifelong responsibility.Participants actively promoted sustainability through education,advocating for responsible consumption,and participating in community-driven environmental initiatives.When individuals develop habits such as energy conservation,waste reduction,and responsible consumption,these actions become second nature,requiring minimal cognitive effort to sustain over time.This consistency is vital in addressing environmental challenges,as one-time actions are insufficient to create lasting change.Collaborative initiatives,community engagement,and institutional support are essential for achieving lasting environmental impact.Nevertheless,the findings can inform educational programs,policy-making,and community-driven sustainability initiatives,reinforcing the idea that both individual actions and collective efforts are necessary to address environmental challenges effectively. 展开更多

Objective This study initially validates the Chinese version of the Physical Activity Questionnaire for Older Children (PAQ-C), which has been identified as a potentially valid instrument to assess moderate-to-vigorous physical activity (MVPA) in children among diverse racial groups. Methods The psychometric properties of the PAQ-C with 742 Hong Kong Chinese children were assessed with the scale's internal consistency, reliability, test-retest reliability, confirmatory factory analysis (CFA) in the overall sample, and multistep invariance tests across gender groups as well as convergent validity with body mass index (BMI), and an accelerometry-based MVPA. Results The Cronbach alpha coefficient (α=0.79), composite reliability value (p=0.81), and the intraclass correlation coefficient (α=0.82) indicate the satisfactory reliability of the PAQ-C score. The CFA indicated data fit a single factor model, suggesting that the PAQ-C measures only one construct, on MVPA over the previous 7 days. The multiple-group CFAs suggested that the factor Ioadings and variances and covariances of the PAQ-C measurement model were invariant across gender groups. The PAQ-C score was related to accelerometry-based MVPA (r=0.33) and inversely related to BMI (r=0.18). Conclusion This study demonstrates the reliability and validity of the PAQ-C in Chinese children. 展开更多

The BOF-key is the performance-based research funding system that is used in Flanders, Belgium. In this paper we describe the historical background of the system, its current design and organization, as well as its effects on the Flemish higher education landscape. The BOFkey in its current form relies on three bibliometric parameters: publications in Web of Science, citations in Web of Science, and publications in a comprehensive regional database for SSH publications. Taken together, the BOF-key forms a unique variant of the Norwegian model: while the system to a large extent relies on a commercial database, it avoids the problem of inadequate coverage of the SSH. Because the bibliometric parameters of the BOF-key are reused in other funding allocation schemes, their overall importance to the Flemish universities is substantial. 展开更多

The mortgage loan has evolved from a local lending instrument into a major global security and its role is unparallel to other financial instruments in the process of financial globalization. This paper explains how technology and financial innovation transformed the mortgage loan from a local security into a premier global security traded worldwide. It examines the fundamental flaws of this process and why it does not work in regards to mortgage lending and the re-securitization products that were created through financial innovation. The findings show that regulation was unable to keep pace with financial innovation, which created an environment where actors in the financial service sector were able to behave geographically irresponsibly by using information asymmetries to their advantage by par- ticipating in moral hazard activities and engaging in other immoral and unethical business practices that were centered around localized geography, which ultimately contributed to the global financial crisis. It also examines the roll of financial innovation in regard to the Lehman Brothers Mini-Bond in Hung and its role as a driving force behind China's newly emerging shadow banking sector. It concludes with a policy recommendation and its implication for China's continued economic development. 展开更多

This paper presents mathematics models that describe and optimize the passenger flow at the airport security checkpoints by applying the queuing theory. Firstly, a Poisson process is used to estimate the flow of passengers waiting for going through the security. Then, the Poisson distribution is combined with a multiple M/M/s model. Following that, an arrival model (passengers’ arriving at the checkpoints preparing for security examination and departure) with Gumbel extreme value estimation is described that predicts the busiest time in the busiest airport. Real case data collected from several major airports worldwide is used for creating a hybrid Poisson model to generate the simulation of passenger volume. At last, Markov Chain theory is applied to the analysis to randomly simulate the flow of enplaned passengers again, and the results of these two simulations are compared and discussed, revealing that the hybrid Poisson model is the more accurate one. After successfully characterizing the passenger flow mathematically, two methods for optimizing the passenger flow are then provided in two different respects: one is bypassing passengers and creating an express pass;while the other one promotes Pre-Check service application. 展开更多

Objective:To explore the meanings and domains for giving communities the capacity to be successful in dengue prevention and control.Methods:One hundred and twenty participants were purposely selected from 4 sub-districts of 4 provinces in Southern Thailand with a high dengue incidence.Sixty community leaders and sixty non-community leaders participated in this study.In-depth interviews(IDIs),as well as focus group discussions (FGDs) with tape-recorders and note-taking,were used to collect data.All records were transcribed verbatim and analyzed by using the Colaizzi method for content analysis.Results:The findings showed that people view the creation of a sustainable dengue community program as possible only with the support of each community in its entirety:"everyone,every sector,all participating,and with continuing activities." Community capacity for dengue prevention and control was dependent on ten domains:1) stakeholder participation, 2) community leadership,3) a core-activities group,4) a problem-solving needs assessment,5) dengue information transfer,6) resource mobilization,7 ) a sense of community for the dengue problem,8) a dengue network partnership,9) critical dengue situation-management,and 10) continuing dengue prevention and control activities.Conclusion:These community capacity domains can be developed into an assessment tool for the community capacity-building process.Community capacity domains require community leaders and non-community leaders to clarify dengue prevention and control assistance required. 展开更多
