AbstractCountries which imposed strict containment measures in response to the COVID-19 pandemic are thought to have faced particular socio-economic challenges. This study assesses the implications of COVID-19 disruptions on local agri-food value chain actors in Kenya and Uganda, as both countries enacted strict lockdowns to limit the spread of the virus. Using survey data from 527 smallholder farmers and 107 small-scale market actors, the study analyses these actors’ vulnerability and resilience. This is operationalised as (1) the exposure of respondents to COVID-19 containment measures, (2) effects of these measures as observed by respondents (e.g. on production or trade and income), and (3) (short-term) coping strategies used by respondents to deal with such impacts. Our results show how containment measures have restricted personal movement and transport options and have limited access to agricultural inputs and markets. This led to a decrease in agricultural production and local trading activities. While both farmers and market actors experienced massive negative income effects, market actors were being hit particularly hard as their livelihoods depend on free movement which was severely curtailed during the pandemic. Actors from both categories often tried to cope by selling livestock, using savings and lowering both food intake and food diversity. Coping strategies were thus short-term and further reduced actors’ resilience by exhausting their buffering capacity and exposing them to the risk of food insecurity.
Does spirea aphid (Aphis spiraecola Patch, Homoptera: Aphididae) overwinter on apple in Central Europe?
Authors: Borbély Csaba , Nagy Csaba , Markó Viktor 
Published: January 2024

AbstractThe native green apple aphid (Aphis pomi DeGeer) and the invasive green spirea aphid (Aphis spiraecola Patch) share apple as a common host plant during the summer months in Central Europe. Various studies suggest that, under certain conditions, the originally host-alternating A. spiraecola is able to overwinter on apple as a winter host, following a similar life history to A. pomi. In this study, we collected stem mothers (fundatrices) and aphids of the second generation (fundatrigeniae) from ten localities throughout Hungary for nine consecutive springs to assess whether A. spiraecola can overwinter on apple as a winter host. All the collected aphid individuals (1126 aphids from 114 stem colonies during the nine years of the study) belonged to A. pomi, indicating that A. spiraecola does not, or very rarely can, overwinter on apple under Central European conditions.
Perfectionism as a moderator of the relationship between orthorexia nervosa and obsessive–compulsive symptoms
Authors: Huynh Phillipa Ann , Miles Stephanie , Nedeljkovic Maja 
Published: January 2024

Abstract
Purpose
Orthorexia nervosa (ON), a proposed disorder describing an obsessive focus on “healthy” eating, is characterised as having overlapping symptoms with obsessive–compulsive disorder. However, ON/obsessive–compulsive (OC) symptom relationships are inconsistently reported. The current study aimed to investigate if the contribution of OC symptoms and beliefs explain variability in ON symptoms and determine if perfectionism, a transdiagnostic factor, moderates the ON/OC symptom relationship.

Methods
The study comprised 190 participants (Mage = 28.63, SDage = 9.88; 80% female) recruited via an undergraduate research programme, social media, advocacy organisations, and a participant registry. Participants completed an online questionnaire assessing ON, OC, and perfectionism symptoms.

Results
A linear regression analysis found OC symptoms and beliefs explained 22.9% variability in ON symptoms (p < 0.001, f2 = 0.38) and perfectionism moderated the ON/OC symptom relationship, where higher levels of perfectionism with higher levels of OC symptoms was associated with higher levels of ON symptoms, explaining 2.2% variability (p = .01, f2 = 0.03).

Conclusion
OC symptoms appear more common in ON than previous studies indicate. However, the interaction between perfectionism and OC symptoms may drive obsessions in ON. Findings help refine our current understanding of ON phenomenology with implications for ON treatment development. Future research should further explore perfectionism in ON phenomenology.

Published: January 2024

AbstractH62 brass material is one of the important materials in the process of electrical energy transmission and signal transmission, and has excellent performance in all aspects. Since the wear behavior of electrical contact pairs is particularly complex when they are in service, we evaluated the effects of load, sliding velocity, displacement amplitude, current intensity, and surface roughness on the changes in contact resistance. Machine learning (ML) algorithms were used to predict the electrical contact performance of different factors after wear to determine the correlation between different factors and contact resistance. Random forest (RF), support vector regression (SVR) and BP neural network (BPNN) algorithms were used to establish RF, SVR and BPNN models, respectively, and the experimental data were trained and tested. It was proved that BP neural network model could better predict the stable mean resistance of H62 brass alloy after wear. Characteristic analysis shows that the load and current have great influence on the predicted electrical contact properties. The wear behavior of electrical contacts is influenced by factors such as load, sliding speed, displacement amplitude, current intensity, and surface roughness during operation. Machine learning algorithms can predict the electrical contact performance after wear caused by these factors. Experimental results indicate that an increase in load, current, and surface roughness leads to a decrease in stable mean resistance, while an increase in displacement amplitude and frequency results in an increase in stable mean resistance, leading to a decline in electrical contact performance. To reduce testing time and costs and quickly obtain the electrical contact performance of H62 brass alloy after wear caused by different factors, three algorithms (random forest (RF), support vector regression (SVR), and BP neural network (BPNN)) were used to train and test experimental results, resulting in a machine learning model suitable for predicting the stable mean resistance of H62 brass alloy after wear. The prediction results showed that the BPNN model performed better in predicting the electrical contact performance compared to the RF and SVR models.

Published: January 2024

Abstract
Objectives
Autistic individuals and those diagnosed with ADHD are at greater risk for social difficulties, with evidence suggesting that the co-occurrence of these neurodevelopmental disorders may further exacerbate social challenges. Though social skill interventions have strong empirical support in autistic populations, fewer evidence-based social skill interventions for adolescents with ADHD exist. Further, the impact of co-occurring autism and ADHD diagnoses on social skill treatment response is unknown. This study aimed to investigate the comparative efficacy of the evidence-based PEERS® for Adolescents social skills intervention in adolescents with ADHD, autistic adolescents, and adolescents with co-occurring ADHD and autism.

Methods
Adolescents (N = 144; ADHD, n = 43; Autism, n = 60; ADHD + Autism, n = 41) and their parents participated in PEERS® for Adolescents and completed questionnaires on social functioning at pre- and post-intervention. PEERS® for Adolescents is a 16-week, parent-assisted social skills intervention that teaches ecologically valid skills related to making and keeping friends as well as handling conflict and rejection in peer relationships.

Results
At baseline, a MANCOVA revealed significant differences in social behavior by diagnostic group (ADHD, Autism, ADHD + Autism), F(10,218) = 3.60, p < .001. However, in a repeated measures MANCOVA, no significant differences in treatment response following PEERS® for Adolescents across diagnostic groups emerged, F(10,214) = 1.34, p = .209. As a whole, participants significantly improved across all assessed outcomes.

Conclusion
Results suggest that adolescents with ADHD, with or without a co-occurring autism diagnosis, benefit from the novel extension of PEERS® for Adolescents, showing improved social skill proficiency and decreased problem behaviors.

Abstract
Leiomyomas are benign tumors, mostly located in the uterus. The pelvic localization is quite rare, and it is associated with unusual growth patterns. It is important to make an adequate differential diagnosis between malignant and benign retroperitoneal neoplasm because treatment is different. When it is not possible to have a precise preoperative diagnosis, a laparoscopic or laparotomy surgical tumorectomy is often required. To obtain a certain diagnosis, the goal of surgery is ensuring the complete excision of neoplasms and preservation of urination, defecation, and sexual function. We report a rare case of a 58-year-old woman who underwent a laparoscopic tumorectomy for a pelvic retroperitoneal leiomyoma. The patient reported occasional episodes of dull pain in the pelvic region. Pelvic contrast CT scan and magnetic resonance imaging (MRI) showed a retroperitoneal solid mass in contiguity with the posterior wall of the uterine body-isthmus, to be referred to as a pedunculated uterine fibroma strictly posteriorly adherent to the sigma. She first underwent to explorative laparoscopy by a gynecologist who did not find any uterine mass. The patient was subsequently admitted to the department of general surgery and has done a second operative laparoscopy which highlighted the presence of an extra-peritoneal para-rectal mass which was completely excised. The histological examination of tumor indicated that it was a leiomyoma. The postoperative course was uneventful, and the patient was discharged in III post-operative day (POD).
An Enhanced Location-Aided Ant Colony Routing for Secure Communication in Vehicular Ad Hoc Networks
Authors: Ramamoorthy Raghu 
Published: January 2024

AbstractThe dynamic characteristics of vehicular ad hoc networks (VANETs) demand reliable and secure communication over wireless media. However, there are significant contradictions in autonomous vehicular systems related to security and privacy. Furthermore, VANETs require seamless data transmission to exchange time-critical data about accidents and traffic. Therefore, VANETs require secure seamless data transmission mechanisms to provide secure reliable communication without communication interruption to exchange time-critical data between vehicles. This paper proposes an Enhanced Location-Aided Ant colony Routing (ELAACR) for VANETs to achieve seamless secure data transmission. The proposed ELAACR is a two-fold scheme in which Phase 1 implements Location-Aided Key Management (LAKM) and Phase 2 implements Ant Colony Routing (ACR). An ACR combined with an LAKM pattern for offering secure and reliable communication. The LAKM scheme works based on the group signature concept to construct a secure network, and an ACR is used to find an efficient secure shortest path for seamless data transmission. The proposed work is simulated in Network Simulator (NS 2.35). By using an efficient and secure shortest path with secure seamless data transmission, the proposed ELAACR achieves an average throughput (T) of 640 Kbps, packet loss rate (PLR) of 0.018%, packet delivery ratio (PDR) of 98.5%, overhead (OH) of 0.157%, and 0.16 s end-to-end delay (EED) compared to Enhanced Hybrid Ant Colony Optimization Routing Protocol (EHACORP) and Fuzzy Based Ant Colony Optimization (F-ANT). The simulation results show that the proposed ELAACR registers better performance in all aspects compared to the existing EHACORP and F-ANT.

Abstract
Many foodborne illness outbreaks originate in food service establishments. We tested two behavioural interventions designed to improve the duration and quality of handwashing. We ran a three-armed parallel trial in a laboratory kitchen, from 7 March to 27 May 2022. Participants were n = 195 workers who handle food. We randomly allocated participants to three groups: Timer – tap-mounted timer that counted seconds while participants washed their hands; Precommitment – agreed to five statements on good hand hygiene before attending the kitchen; and Control. Participants completed a food preparation task under time pressure. Cameras focused on the sink captured handwashing. Outcome measures were number of times participants washed their hands; number of times they washed their hands using soap; number of times they washed using soap and washed the backs of their hands; and mean duration of handwashing attempts using soap. Participants in Timer washed their hands for 1.9 s longer on average than Control (β = 2.20, 95% CI = 0.34-4.06, p = 0.021). Participants in Precommitment washed their hands for 2.5 s longer on average than Control (β = 2.30, 95% CI = 0.33-4.27, p = 0.022). We found no statistically significant differences on any other outcome measure.
Assertions: Deterrent or Handicap? A Reply to Graham (2020)
Authors: Bruner Justin P. 
Published: January 2024

Abstract
According to one influential tradition, to assert that p is to express a belief that p. Yet how do assertions provide strong evidence for belief? Philosophers have recently drawn on evolutionary biology to help explain the stability of assertive communication. Mitchell Green suggests that assertions are akin to biological handicaps. Peter Graham argues against the handicap view and instead claims that the norms of assertion are deterrents. Contra Graham, I argue that both mechanisms may play a role in assertive communication, although assertions as deterrents will often fail to provide strong evidence for belief.

Published: January 2024

AbstractVarious magmatisms during the subduction-collision process are crucial to reveal the long-term tectonic evolution of the eastern Central Asian Orogenic Belt. In this paper, we present major and trace elements of whole-rock, zircon U-Pb dating and Hf isotope of the Shanmen pluton. Results imply that the Shanmen pluton consists of quartz diorite and mylonitic granite, with zircon U-Pb ages of 263.7–259.6 Ma. The studied quartz diorite contains high Sr/Y (51.19–90.87) and (La/Yb)N (7.82–13.62) ratios, and belongs to adakitic rocks. Coupled with the positive εHf(t) values of +5.71 to +12.8 with no obvious Eu anomaly, we propose that quartz diorite is the product of the interaction between different degrees of slab melt and the overlying mantle wedge. In contrast, the mylonitic granite has lower MgO (0.28 wt% – 0.47 wt%) contents and positive εHf(t) values of +7.79 to +10.15, indicating an affinity with I-type granite originated by partial melting of the intermediate-basic lower crust. The geochemical characteristics and lithological assemblages, along with the Permian magmatic rocks in the Changchun-Kaiyuan area displaying arc rocks affinity, propose their formation is related to the southward subduction of the Paleo-Asian Ocean (PAO). Based on this study and previous evidence, we lean towards adopting a middle-late Permian slab break-off model, wherein the PAO did not close until the late Permian.
Safeguarding South African Consumers’ Socio-Economic Rights During COVID-19: Competition Commission v Babelegi Workwear and Industrial Supplies
Authors: Tavuyanago Simbarashe , Mpofu Kudzai 
Published: January 2024

AbstractThis article explores the responses of the South African competition authorities to the impact of the COVID-19 pandemic on the socio-economic rights of consumers in relation to the price gouging of essential and medical supplies. After discussing the constitutional and legislative context of socio-economic rights and excessive pricing, it examines the first case in which the competition authorities were called upon to decide on the excessive pricing of medical supplies during COVID-19. The article finds that, while the competition authorities were swift to interpret the Competition Act widely and act against suppliers charging excessive prices, there remains a gap in South Africa's legislative framework as there is no specific legislation regulating price gouging during states of pandemic or disaster. The article identifies the need for legislative development and concludes by offering recommendations for addressing future incidents of price gouging.
In defence of qua-Christology
Authors: Rubio Daniel 
Published: January 2024

Abstract
Recent analytic theology has seen a wave of excellent work on the fundamental problem of Christology, the question of how one and the same person can be human full stop and divine full stop. Along the way, new objections have been raised for a venerable family of Christological views, whose distinctive is the employment of qua-devices to dissolve the difficulties stemming from the dual nature doctrine of Chalcedon and its successors. My objective in this article is twofold. First, I propose to lay out a hierarchy of principles that should guide the search for a Christological theory. I then use these principles to illuminate the best qua-theoretic approach to Christology. Finally, I argue that the best qua-theory is at worst on a par with major recent views.
Religion and Trust in Hong Kong
Authors: Cai Yongshun , Hung Sin Yu 
Published: January 2024

AbstractAffiliation with different religions can have different effects on practitioners’ trust in state institutions and in social actors. Based on a survey of 3,740 residents in Hong Kong in 2021, we examine the relationship between religious affiliation and believers’ trust in the political authorities in Beijing and Hong Kong and in civil actors in the city. We find that affiliation with traditional Chinese religions and Eastern religions has a positive and significant effect on believers’ trust in the political authorities, whereas belief in Western religions does not have such an effect. Affiliation with Western religions, however, has a stronger positive and significant effect on interpersonal trust and on tolerance for unconventional behaviour. These findings shed light on the interaction between the government and religious groups in Hong Kong after 1997.

Abstract
Adherence to post-exposure prophylaxis and post-exposure vaccination (PEV) is an important measure to prevent rabies. The purpose of this study was to explore the adherence to the vaccination protocol and its influencing factors among rabies-exposed patients in Shenzhen, China. A cross-sectional survey was conducted in a tertiary hospital in Shenzhen, China, to obtain epidemiological characteristics of patients; knowledge, attitude, and practice scores of rabies prevention; and medical records. A total of 326 patients requiring full rabies PEV were included in this study, and only 62% (202) completed the full course of vaccination according to the norms of the vaccination guidelines. After multifactor logistic regression, the factors influencing adherence to vaccination were as follows: age 31 to 40 years, time spent to reach the nearest rabies prevention clinic was >60 min, the time of injury was at night to early morning, the place of injury was a school/laboratory, the animal causing injury was a cat, the health status of the animal causing injury could not be determined, and patients with higher practice scores (all p<0.05). Understanding the factors influencing rabies vaccination adherence among rabies-exposed patients in urban areas of China and promote changes in patients’ practice toward rabies prevention is essential for rabies elimination by 2030.
Shape-shifting and Strategic In/visibility: Comparing Sex Work Activism in Singapore and the Philippines
Authors: Parmanand Sharmila 
Published: January 2024

AbstractResearch on public health, crime, and policing regularly discusses sex workers in Southeast Asia but rarely recognises them as agents of social and political activism. This paper shows that sex workers and their allies in Singapore and the Philippines have long and rich histories of challenging their criminalisation and stigmatisation through cultural activism, political advocacy, consciousness-raising, and the provision of direct services to fellow sex workers. Using feminist ethnography, including interviews and participant observation with Project X in Singapore and the Philippine Sex Workers Collective, this paper explores how sex work activists have strategically adapted to their political environments. In Singapore, they maintain resistance through ‘shape-shifting,’ working within state-sanctioned mechanisms, positioning themselves as public health service providers, and creating spaces for radical political advocacy. In the Philippines, where an anti-sex work position is more deeply entrenched within dominant social blocs, sex work activists aggressively criticise state policies on social media and in carefully vetted forums but remain strategically invisible to avoid exposure, harassment, misrepresentation, and prosecution. This paper looks at how sex work activists engage in claims-making — underscoring the differences in the political resonance of human rights in both countries — and interrogates how sex work activism challenges social hierarchies, especially concerning migrants and trans individuals. Overall, it contributes to a richer understanding of non-traditional forms of political activism in Southeast Asia and makes visible sex workers’ contributions to feminism and labour movements in the global south and non-Western contexts.
