Sarcasm detection in online comments using machine learning
Authors: Šandor Daniel , Bagić Babac Marina 
Published: July 2023

Purpose
Sarcasm is a linguistic expression that usually carries the opposite meaning of what is being said by words, thus making it difficult for machines to discover the actual meaning. It is mainly distinguished by the inflection with which it is spoken, with an undercurrent of irony, and is largely dependent on context, which makes it a difficult task for computational analysis. Moreover, sarcasm expresses negative sentiments using positive words, allowing it to easily confuse sentiment analysis models. This paper aims to demonstrate the task of sarcasm detection using the approach of machine and deep learning.

Design/methodology/approach
For the purpose of sarcasm detection, machine and deep learning models were used on a data set consisting of 1.3 million social media comments, including both sarcastic and non-sarcastic comments. The data set was pre-processed using natural language processing methods, and additional features were extracted and analysed. Several machine learning models, including logistic regression, ridge regression, linear support vector and support vector machines, along with two deep learning models based on bidirectional long short-term memory and one bidirectional encoder representations from transformers (BERT)-based model, were implemented, evaluated and compared.

Findings
The performance of machine and deep learning models was compared in the task of sarcasm detection, and possible ways of improvement were discussed. Deep learning models showed more promise, performance-wise, for this type of task. Specifically, a state-of-the-art model in natural language processing, namely, BERT-based model, outperformed other machine and deep learning models.

Originality/value
This study compared the performance of the various machine and deep learning models in the task of sarcasm detection using the data set of 1.3 million comments from social media.

Published: July 2023

Purpose
This study aimed at exploring support for older people in protracted displacement in Nigeria, emphasising the available support and the gap in the support provided to them.

Design/methodology/approach
Qualitative interviews were used to collect data from ten displaced older people in New-Kuchingoro internally displaced persons (IDP) camp Abuja, Nigeria. The collected data were analysed thematically with NVivo 12.

Findings
Results show that older people received material, emotional and psychological supports from their families, neighbours, friends, religious organisations and non-governmental organisations. Several gaps were identified in the support provided to displaced older people. For example, their special nutritional or medical needs were neglected, and their support was primarily material, sporadic and spontaneous, as there is no existing framework guiding the care and support of older people in displacement.

Research limitations/implications
This study provides a foundation for further research on older people in displacement, an area that has received minimal scholarly attention.

Practical implications
The paper recommends that researchers and displaced persons’ care providers should pay more attention to the peculiar support needs of this less visible vulnerable group and adopt the internal displacement policy for the long-term protection of older people in displacement.

Originality/value
Older people in displacement remain less visible as humanitarian aid programmes and research focus more on women and children. This lack of attention may put older people in displacement at more risk as their peculiar needs may not be met. To the best of the authors’ knowledge, this study is the first to examine the gap in support for older people in displacement in Nigeria.

Published: July 2023

Purpose
The purpose of this paper is to describe six recovery-oriented peer support experiences and strategies implemented in different regions of Brazil in the past 12 years, and explore challenges to their development and potential for empowerment and citizenship.

Design/methodology/approach
In this paper, a group of stakeholders in mental health services involving people with lived experience of severe mental illness describe their experiences with services of peer support. These were all conducted in Brazil and in partnership with the International Recovery and Citizenship Collective (IRCC) and The Yale Program for Recovery and Community Health. The authors met monthly to exchange experiences, studies and practices, and six experiences were selected, described, analyzed and compared. A discussion of these experiences, their challenges, impact and potential followed.

Findings
The explored experiences emphasize that peer support, lived experience leadership and advocacy are feasible in the Brazilian mental health system and can help advance the Brazilian Psychiatric Reform.

Research limitations/implications
This paper is limited to the experience of researchers already engaged in peer support work in six cities in Brazil. Although they represent several different regions in Brazil, there are areas it has not reached. Further research should address and provide a broader view of peer support and recovery strategies spreading in the country.

Social implications
These experiences demonstrate the feasibility and acceptability of the recovering citizenship approach to reduce stigma, promote empowerment, autonomy, activism and advocacy, and increase a sense of belonging for those in recovery and marginalized by society. The Brazilian psychiatric reform can benefit from including peer supporters as mental health treatment providers.

Originality/value
This paper provides a novel view of the state of the art of peer support initiatives in Brazil and can inspire individuals, government and communities as they see and understand the breadth, depth and meanings of these peer support experiences.

Authors: A. Subaveerapandiyan , N. Sakthivel , Amees Mohammad , Yadav Upasana 
Published: July 2023

Purpose
This study aims to explore the potential of virtual positioning systems (VPSs) in revolutionising library access. It examines the benefits and challenges associated with implementing VPSs.

Design/methodology/approach
The study takes a comprehensive approach by analysing library users’ current challenges in accessing physical resources and services within traditional library settings. It analyses the benefits of VPSs in enhancing library access, considering factors such as improved navigation, accessibility for personalised recommendations, virtual tours and interactive experiences. The study also examines the implications of implementing VPSs regarding library resource management, staff training and infrastructure requirements.

Findings
The findings reveal that VPS has the potential to address various challenges faced by library users, such as limited availability of resources, inconvenient locations and inadequate access for individuals with special needs. VPS offers improved navigation, enhanced accessibility, personalised recommendations, virtual tours and interactive experiences. Implementing VPSs requires robust technological infrastructure, user adoption, privacy considerations and system maintenance. Libraries must invest in hardware, network infrastructure, staff training and data protection measures.

Originality/value
This study contributes to the ongoing discourse surrounding the transformation of libraries and the assimilation of emergent technologies. It highlights the potential of VPSs in revolutionising library access. By embracing the latent potential of VPSs, libraries can transcend physical boundaries, enhance user experiences and ensure seamless access to a wealth of resources in a digitised world.

Abstract

Shrubs are expanding across a warming Arctic, evident from range expansion and increases in biomass, stature and cover. This influences numerous aspects of Arctic ecosystems. While shrub growth is generally positively associated with summer temperature, tundra ecosystems are characterised by abiotic gradients on small spatial scales (metres), and the Arctic climate and its year‐to‐year variability are changing rapidly. Hence, it is often unclear to what extent climate‐growth associations are scalable to future climate scenarios and across environmental gradients within ecosystems. Here, we investigate the stability of climate–growth associations of Arctic dwarf shrubs across small‐scale (metre to kilometre) topographic gradients and decadal timescales.

We constructed ring width series (1974–2018) for a common Arctic dwarf shrub (Betula nana) for three representative types of subsites in the Siberian lowland tundra: higher elevation, lower elevation and thermokarst‐affected (thaw ponds) terrain. We quantified decadal variability in climate–growth associations across subsites using partial least squares regression and a moving window approach.

We found consistently positive association of shrub radial growth with summer temperature, but substantial spatial and temporal variability in precipitation response. Association of shrub growth with summer rainfall increased in recent decades. Shrubs on elevated sites showed particularly strong response to rainfall following drier periods, and a negative association with recent snowfall extremes. Shrubs sampled from thaw ponds showed strong positive association with rainfall, followed by high shrub mortality after an extremely wet summer. This likely resulted from waterlogging due to thermokarst.

Synthesis. Our findings imply that the response of shrub growth to changes in Arctic precipitation regimes is regulated by (i) macro‐ (kilometre‐scale) and micro‐topographical (metre‐scale) gradients, (ii) colimitation between temperature and moisture and (iii) potentially nonlinear responses to precipitation extremes. This suggests that the scalability of precipitation‐growth relationships for Arctic shrubs across dynamic tundra landscapes and future climate scenarios is limited. We recommend that future climate–growth studies on Arctic tundra shrubs simulate future precipitation changes across spatial gradients and include detailed microsite and shrub physiological monitoring.
Effects of remittances on food security in sub‐Saharan Africa
Authors: Seydou Lankoande Lamoussa 
Published: July 2023

AbstractThe objective of this research was to analyze the effects of remittances on food security in sub‐Saharan Africa (SSA), while assessing the role of governance. The analyses covered a panel of 26 SSA countries over the period from 2002 to 2017. Based on the double least squares method, two main results were obtained. On the one hand, remittances have a positive effect on overall food security and on each of its dimensions in SSA. On the other hand, this positive effect of remittances on food security and its dimensions is increasingly important when the quality of governance improves.
Labeling effects of initial juvenile justice system processing decision on youth interpersonal ties*

Published: July 2023

AbstractThe juvenile justice system can process youth in myriad ways. Youth who are formally processed, relative to being informally processed, may experience more public and harsh sanctions that label youth more negatively as “deviant.” Drawing on labeling theory, the current study evaluates the relative effect of formal justice system processing on the interpersonal dynamics of youth peer networks. Using data from the Crossroads Study, a multisite longitudinal sample of first‐time adolescent offenders, the current study applies augmented inverse probability weighting and generalized mixed‐effects models to estimate the effects of formal processing on friendship selection processes of homophily and withdrawal and considers whether these effects vary by race and ethnicity. Consistent with expectations of homophily, formally processed youth acquire more new deviant peers and fewer nondeviant peers during the 3 years after their initial processing decision compared with informally processed youth. The findings suggest no differences exist across processing types in withdrawal from friends. These effects were consistent across racial and ethnic groups. Ultimately, this study explores the dynamic interpersonal mechanisms associated with labeling theory and offers additional insight into the negative effects of formal processing.
Poland: Political Developments and Data in 2022

Published: July 2023

AbstractThe Russian invasion of Ukraine caused a flow of refugees to Poland on a scale unprecedented in Europe since Second World War. Polish civil society, soon joined by government institutions, responded by offering the refugees, who counted in millions, shelter, material and social welfare assistance and legal accommodation. The war next door turned Poland into an EU and NATO frontline country, which led to more intense contacts between the Polish government and its Western partners, including the United States. This, however, did not help the government, which had marginalized itself within the EU by its own past actions, to resolve its disputes with the European Commission and the Court of Justice. Similarly, the uniform condemnation of the Russian aggression by all major political parties did not bridge the gap between the governing Law and Justice party and the opposition or even reduce the intensity of political conflicts.

Published: July 2023

AbstractBackgroundInvasive recording of His bundle signals (HBS) in electrophysiological study (EPS) is important in determining HV interval, the time taken to activate the ventricles from the His bundle. Noninvasive surface measurements of HBS are attempted by averaging typically 100–200 cardiac cycles of ECG time series in body surface potential mapping (BSPM) and in magnetocardiography (MCG) which records weak cardiac magnetic fields by highly sensitive detectors. However, noninvasive beat‐by‐beat extraction of HBS is challenged by ramp‐like atrial signals and noise in PR segment of the cardiac cycle.MethodsBy making use of a signal‐averaged trace showing prominent HBS as a guide trace, we developed a method combining interval‐dependent wavelet thresholding (IDWT) and signal space projection (SSP) technique to eliminate artifacts from single beats. The method was applied on MCG recorded on 21 subjects with known HV intervals based on EPS and noninvasive signal‐averaging, including five subjects with BSPM recorded subsequently. The method was also applied on stress‐MCG of a subject featuring autonomic dynamics.ResultsHBS could be extracted from 19 out of 21 subjects by signal‐averaging whose timing differed from EPS between −8 and 11 ms as tested by 2 observers. HBS in single beats were seen as aligned patterns in inter‐beat contours and were appreciable in stress‐MCG and conspicuous than BSPM. The performance of the method was evaluated on simulated and measured MCG to be adequate if the signal‐to‐noise ratio was at least 20 dB.ConclusionsThese results suggest the use of this method for noninvasive assessments on HBS.
Citizenship pressure and knowledge hiding: The mediating role of citizenship fatigue and the moderating role of supervisor–subordinate guanxi

Published: July 2023

AbstractDrawing on conservation of resources (COR) theory, we examine the relationship between citizenship pressure and knowledge hiding, exploring the underlying mechanism between the two through citizenship fatigue and supervisor–subordinate guanxi. Two three‐wave sets of data were collected and analyzed with PROCESS. Study 1 revealed that employees' perceived pressure to engage in organizational citizenship behavior (OCB) can lead them to experience citizenship fatigue and to seek to conserve resources through deceptively hiding knowledge (i.e., evasive hiding and playing dumb). However, rationalized hiding will not be adopted by employees as a strategy to reserve resources under citizenship pressure. Supervisor–subordinate guanxi also serves as a reverse moderator, in that high guanxi mitigates the direct impact of citizenship pressure on citizenship fatigue and the indirect impact of citizenship pressure on evasive hiding and playing dumb through citizenship fatigue. Study 2 replicated and extended the findings of Study 1 by considering the negative affect as a potential mediator and the leader–member exchange (LMX) as a potential moderator. The findings show that citizenship pressure has a positive effect on evasive hiding and playing dumb through the mediating role of citizenship fatigue; and supervisor–subordinate guanxi negatively moderates the positive effect of citizenship pressure on citizenship fatigue and the mediating effect of citizenship fatigue, whereas LMX has no significant moderating effect on these linkages. This research advances our understanding of the “dark side” of OCB and enriches knowledge hiding studies by introducing a new predictor about extra‐role work stressors.

Published: July 2023

AbstractBackgroundLabor after cesarean (LAC) remains an optional delivery method among healthy pregnant individuals. Exploring women's attitudes, preferences, reasons for previous cesarean delivery, and the incentives underlying pregnant individuals' preferences could help us understand their choice of delivery mode. In this study we evaluated the preferences and attitudes of eligible pregnant women regarding participation in a LAC in Foshan, China.MethodsA cross‐sectional survey was conducted among 438 pregnant individuals with one prior cesarean delivery (CD) who attended their antenatal examination at a tertiary hospital in southern China, between November 1, 2018, and October 31, 2019. Information on demographic characteristics, obstetric data, preferences for LAC, and incentives for LAC were analyzed.ResultsOverall, 85.4% (374/438) of women preferred LAC if they did not have contraindications before delivery, whereas 12.3% (54/438) refused and 2.3% (10/438) were unsure. Participants reported that the most important factors affecting their willingness to undergo LAC were safety indicators (i.e., “ability of hospitals to perform emergency cesarean delivery” [score of 9.28 ± 1.86]), followed by accessibility indicators (i.e., “priority bed arrangements” [score of 9.17 ± 1.84]). Logistic regression analysis indicated that neonatal wellbeing with the prior CD was an independent influencing factor (OR = 2.235 [95%CI: 1.115–4.845], p = 0.024) affecting willingness to access LAC in the subsequent pregnancy.ConclusionsWe found a high preference for LAC among pregnant individuals without contraindications before delivery in southern China. Healthcare providers need to ensure access to LAC and increase pregnant individuals' LAC willingness through high‐quality shared decsision‐making in alignment with patient preferences.

AbstractBackgroundBoth teacher support and math attitudes have been identified as associated with math anxiety in primary school children. However, little is known about how they are interrelated longitudinally.AimsThe study was designed to examine the associations among perceived teacher support, math attitudes, and math anxiety in Chinese primary school students.SampleThe sample included 1802 students (56.16% boys) initially in the third and fourth grades in two public schools in China.MethodsA three‐year cross‐lagged panel design was conducted to examine the associations among perceived teacher support, math attitudes, and math anxiety. Moreover, a multigroup analysis was used to examine whether the associations varied by gender.ResultsThere were reciprocal associations over time between math attitudes and math anxiety. Meanwhile, both math attitudes and math anxiety significantly predicted perceived teacher support one year later, but not vice versa. Further, the association between T1 math anxiety and T3 perceived teacher support was mediated by T2 math attitudes; the association between T1 math attitudes and T3 perceived teacher support, on the other hand, was mediated by T2 math anxiety. Moreover, there were no significant gender differences in these associations.ConclusionsMath anxiety and math attitudes objectively affected each other, and both of them significantly predicted later perceived teacher support, but not vice versa. This study demonstrates that children are not merely passive recipients of environmental influences and offers theoretical guidance for intervention practices that aim to reduce the risk of math anxiety.
