Published: November 2022

Purpose
This study aims to provide a comprehensive review and bibliometric analysis of the literature in the field of science, technology, engineering and mathematics (STEM) education over the past 15 years, with a specific focus on global distribution and research trends.

Design/methodology/approach
This study collected 1,718 documents from the Web of Science (WOS) database and analyzed their timeline distribution, geographical distribution, research topics, subject areas, learning stages and citation burst using a bibliometric approach with VOSviewer and Citespace.

Findings
Results indicated that: overall, STEM education has increasingly gained scholarly attention and is developing diversely by emphasizing interdisciplinary, cross-domain and regional collaboration. In terms of global collaboration, a collaborative network with the USA in the center is gradually expanding to a global scope. In terms of research themes, four key topics can be outlined including educational equity, pedagogy, empirical effects and career development. Social, cultural and economic factors influence the way STEM education is implemented across different countries. The developed Western countries highlighted educational equity and disciplinary integration, while the developing countries tend to focus more on pedagogical practices. As for research trends, eastern countries are emphasizing humanistic leadership and cultural integration in STEM education; in terms of teachers’ professional development, teachers’ abilities of interdisciplinary integration, technology adoption and pedagogy application are of the greatest importance. With regards to pedagogy, the main focus is for developing students’ higher-order abilities. In terms of education equity, issues of gender and ethnicity were still the hottest topics, while the unbalanced development of STEM education across regions needs further research.

Originality/value
This study provides a global landscape of STEM education along the timeline, which illustrates the yearly progressive development of STEM education and indicates the future trends.
Are you a trend setter or a straggler? Social drivers and customer shift toward co-creating value with self-service technologies
Authors: Galdolage Badra Sandamali 
Published: November 2022

PurposeFuture service interactions are anticipated to use humanoid robots in a society that is shifting to a digitalized era. Currently, it is evident that many businesses are replacing service interactions with self-service technologies (SSTs). This movement creates substantial societal changes that researchers have not paid sufficient attention to comprehend. In this setting, the purpose of this study is to examine the social drivers that influence customer mobility toward co-creating value via SSTs. The study also seeks to discover variations in customers' willingness and capacity to adopt SSTs.Design/methodology/approachTo fulfill the research aims, a qualitative technique was adopted, with semistructured interviews conducted with 25 SST users from varied demographic backgrounds. To recruit individuals for the study, a nonprobabilistic purposeful sampling technique was adopted, with the goal of employing information-rich instances. The data were analyzed using thematic analysis.FindingsThe study identified eight social drivers that are important in the customer transition toward co-creating value with SSTs. According to the study, SSTs are characterized as a social trend in which adoption is accepted (social norm) and modifies social connections in a new direction. Using SSTs has evolved into a socializing tool that gives people social acknowledgment. Some people see SSTs as social pressure, putting them at a disadvantage if they do not adopt. People, on the other hand, acquire sufficient social support and independence to use SSTs. Customers were categorized into four groups depending on their willingness and ability to embrace SSTs: trendsetters, dreamers, old-fashioned and stragglers.Practical implicationsIn practice, service providers can use this knowledge to successfully promote their SSTs and create enhanced client experiences through technological interfaces.Originality/valueThe study adds new knowledge by identifying social determinants in customer shifts toward SSTs, a phenomenon that has not been studied previously, and it adds to marketing theory by proposing a typology to group customers based on their ability and willingness to embrace SSTs.

Authors: Suhartanto Dwi , Djatnika Tjetjep , Suhaeni Tintin , Setiawati Lina 
Published: November 2022

Purpose
This study aims to scrutinize the halal trust model by integrating the quality and valence theory in the mobile food purchasing service during the COVID-19 outbreak.

Design/methodology/approach
This research uses data from 368 Muslim customers collected via an online survey from Bandung, West Java, Indonesia. This study uses partial least square modelling to appraise the formation of halal trust, including halal food quality, mobile apps quality, perceived benefit and health risk as drivers and loyalty as the consequence.

Findings
The data analysis notes that the combination of perceived quality and valence theory provides a comprehensive understanding of halal trust in mobile halal food purchasing during COVID-19. This study also verifies the crucial role of halal food quality and mobile apps quality in gaining halal trust.

Research limitations/implications
This study used data from Muslim customers of the greater Bandung, Indonesia. The data limited the generalization of this study's findings. Moreover, this study predicted halal trust by integrating perceived benefit, perceived trust and quality as the predictors, whereas other determinants such as commitment and reputation were not included. Therefore, future researchers can incorporate these issues in their future halal trust research.

Practical implications
To gain Muslim trust, this study recommends managers whose halal food is sold via mobile apps ensure that their halal food has a quality standard, made of, and processed according to Islamic values. Next, having a high-quality mobile app is also a must.

Originality/value
This study is early research that examines the integration of the quality and valence theory to evaluate halal trust in mobile halal food purchasing during COVID-19.
Intersection control strategy optimization based on exchangeable lanes modeling
Authors: Liu Bo , Hou Jingwen , Ma Xiaoping , Shi Mengtong , Lu Sibo , Wang Ruoxuan 
Published: November 2022

Purpose
Due to the conflicts between left turn traffic and opposite straight-going traffic in urban traffic network, some of the traffic lanes cannot be used to discharge vehicles during its green phases and the intersection capacity can be greatly reduced. This study/paper aims to reduce the effect of conflicts and increase its capacity through the reasonable pre-signal phase time with the exchangeable lanes.

Design/methodology/approach
This paper took into consideration various influence factors to intersection capacity and formulated the capacity optimization model based on 0-1 mixed-integer programming model. This model is efficiently solved by standard branch-and-bound algorithms.

Findings
The authors took an intersection as an example and solved the optimal signal timing and entrance lane capacity via this model. Then, simulations were carried out to verify the effect of the exchangeable lanes strategy of this intersection through the simulation software VISSIM and take the traffic volume and delay as outputs, which indicated that this model has better performance.

Originality/value
The front-end control strategy can not only exploit the full potential of the intersection but also significantly improve the operational efficiency of the intersection. It plays a positive role in improving urban intersection congestion.

AbstractRecently, it has been suggested that central and peripheral toxicities identified in persons with substance use disorder (SUD) could be partially associated with an imbalance in reactive oxygen species and antioxidant defenses. We conducted a systematic review and meta‐analysis to investigate whether SUD is associated with oxidative stress and to identify biomarkers possibly more affected by this condition. We have included studies that analysed oxidant and antioxidant markers in individuals with SUD caused by stimulants, alcohol, nicotine, opioids, and others (cannabis, inhalants, and polysubstance use). Our analysis showed that persons with SUD show higher oxidant markers and lower antioxidant markers than healthy controls. SUD was associated specifically with higher levels of oxidant markers malondialdehyde, thiobarbituric acid reactive substances and lipid peroxidation. Conversely, the antioxidant superoxide dismutase and the total antioxidant capacity/status were lowered in the SUD group. A meta‐regression analysis revealed that persons with alcohol use disorder had higher oxidative stress estimates than those with stimulant use disorder. Moreover, individuals evaluated during abstinence showed smaller antioxidant effect sizes than non‐abstinent ones. Our findings suggest a clear oxidative imbalance in persons with SUD, which could lead to cell damage and result in multiple associated comorbidities, particularly accelerated aging.
Disrupted functional connectivity of the brain reward system in substance use problems: A meta‐analysis of functional neuroimaging studies
Authors: Dugré Jules R. , Orban Pierre , Potvin Stéphane 
Published: November 2022

AbstractExtensive literature suggests that the brain reward system is crucial in understanding the neurobiology of substance use disorders. However, evidence of reliable deficits in functional connectivity across studies on substance use problems remains limited. Therefore, a voxel‐wise seed‐based meta‐analysis using brain regions of the reward system as seeds of interest was conducted on 96 studies representing 5757 subjects with substance use problems. The ventromedial prefrontal cortex exhibited hyperconnectivity with the ventral striatum and hypoconnectivity with the amygdala and hippocampus. The executive striatum showed hyperconnectivity with the motor thalamus and dorsolateral prefrontal cortex and hypoconnectivity with the anterior cingulate cortex and anterior insula. Finally, the limbic striatum was found to be hyperconnected to the orbitofrontal cortex and hypoconnected to the precuneus compared with healthy subjects. The current study provided meta‐analytical evidence of deficient functional connectivity between brain regions of the reward system and cortico‐striato‐thalamocortical loops in addiction. These results are consistent with deficits in motivation and habit formation occurring in addiction, and they highlight alterations in brain regions involved in socio‐emotional processing and attention salience.

AbstractBackgroundExtracorporeal membrane oxygenation (ECMO) became an accepted therapy for the treatment of severe acute respiratory distress syndrome and chronic obstructive pulmonary disease. However, ECMO systems are still prone to thrombus formation and decrease of gas exchange over time. Therefore, it is necessary to conduct qualified studies to identify parameters for optimization of ECMO systems, and especially the oxygenator. However, commercially marketed oxygenators are not always appropriate and available for certain research use cases. Therefore, we aimed to design an oxygenator, which is suitable for various test conditions such as blood tests, numerical simulation, and membrane studies, and can be modified in membrane area size and manufactured in laboratory.MethodsMain design criteria are a homogeneous blood flow without stagnation zones, low pressure drop, manufacturability in the lab, size variability with one set of housing parts and cost‐efficiency. Our newly designed oxygenator was tested comparatively regarding blood cell damage, gas transfer performance and pressure drop to prove the validity of the design in accordance with a commercial device.ResultsNo statistically significant difference between the tested oxygenators was detected and our new oxygenator demonstrated sufficient hemocompatibility. Furthermore, our variable oxygenator has proven that it can be easily manufactured in the laboratory, allows to use various membrane fiber configurations and can be reopened easily and non‐destructively for analysis after use, and the original geometry is available for numerical simulations.ConclusionTherefore, we consider this newly developed device as a valuable tool for basic experimental and numerical research on the optimization of oxygenators.

Published: November 2022

AbstractIntroductionCulturally relevant developmental screening is one of the best ways to appropriately identify developmental delays and disabilities in children as early as possible across diverse cultural backgrounds. This study aimed to adapt the Parents' Evaluation of Developmental Status (PEDS) tools for a low‐income community in South Africa by using a detailed multiphased cultural and contextual adaption process.Method and ResultsA three‐phase mixed‐method design relying on triangulation of data was used. Data were collected at an immunization clinic in a low‐income community in Mamelodi, South Africa. Phase 1 was a focus group discussion with 11 community participants. The topics explored the possible changes to the PEDS tools to make them more relevant to the community. Phase 1 informed Phase 2 where 12 early childhood development experts achieved consensus through a two‐round survey on a modified Delphi method. In Phase 3, a draft of the PEDS tools‐SA was presented to the authors of the PEDS tools for final approval. Of 55 questions that were adapted for the PEDS tools‐SA, two original questions (3.6%), 14 questions from the expert suggestions (25.4%) and 39 from the community participant's suggestions (71%) were included. A final version of the PEDS tools‐SA was created.ConclusionThis study used a systematic method to adapt the PEDS tools to create the culturally appropriate PEDS tool‐SA for a low‐income community in South Africa, informed by community stakeholders' views from the first step. This resulted in a high‐quality adaptation process that is more likely to result in a tool that is more acceptable to caregivers from a low‐income South African community.

AbstractPurposeThis study was to explore whether Ginkgo biloba extract (GBE) improve memory impairment by alleviating neuroinflammation signaling in mice with status epilepticus.MethodsThe status epilepticus (SE) mice model was established by pilocarpine and treated with 100 mg / kg of GBE for 14 days. Spontaneous alternation of Y‐maze and new object recognition were used to explore memory impairment. To examine glial cell activation, we performed immunohistochemistry and immunofluorescence staining. The activation of NF‐κB signaling and the expression level of lncRNA‐COX2 were detected by Western blot and qRT‐PCR, respectively. Adeno‐associated virus lncRNA‐COX2 was injected into mice for overexpression of lncRNA‐COX2.ResultsAfter GBE treatment, the spontaneous alternation rate and the recognition coefficient in SE mice were both increased. Moreover, activation of glial cells, NF‐κB signaling and lncRNA‐COX2 were significantly decreased in SE mice.In the GBE‐treated SE mice with lncRNA‐COX2 overexpression, NF‐κB signaling was up‐regulated again; the reduced level of inflammation factors was reversed; the GBE‐rescued spontaneous alternation rate of Y‐maze was eliminated.ConclusionOur results suggested that GBE reduces the hippocampal inflammation by down‐regulating lncRNA‐COX2 / NF‐κB signaling in the SE mice, leading to the decrease of neuronal damage and the improvement of memory functions.

AbstractAimThe mountainous regions in SW Asia harbour a high number of endemic species, many of which are restricted to the high‐elevation zone. The (sub)alpine habitats of the region are under particular threat due to global change, but their biodiversity hotspots and conservation status have not been investigated so far.LocationSubalpine‐alpine habitats of SW Asia.MethodsDistribution data of all (sub)alpine vascular plant species of the region were compiled, resulting in 19,680 localities from 1672 (sub)alpine species, the majority of them being restricted to the region (76%). Six quantitative indices of species diversity were used on the basis of 0.5° × 0.5° grid cells to identify (sub)alpine hotspots. Hotspots whose surface area in the (sub)alpine zone was covered by nature reserves maximally by 10% were defined as conservation gaps.ResultsA high proportion (80%) of the endemic species of the study area is range‐restricted and narrowly distributed. The results of all six indices were highly correlated. Using the top 5%, 10% and 20% richest cells supported by any index, 32, 53 and 98 cells, respectively, were identified as Hotspots. Almost 60% of these Hotspots at all three levels were identified as unprotected (i.e. constituted Conservation Gaps). Generally, only 22%, 18% and 16%, respectively, of the alpine surface area of the identified Hotspots were covered by nature reserves for the top 5%, 10% and 20% richest cells, respectively.Main conclusionsAlthough the rate of protection in (sub)alpine Hotspots exceeds that of the entire region it is still insufficient, because these Hotspots are much richer in endemic and in range‐restricted species, but at the same time are under high pressure of global change. Therefore, the establishment of new nature reserves with high conservation efficiency in (sub)alpine habitats with a particular focus on the identified Hotspots is strongly recommended.

Published: November 2022

AbstractCutting performances of silicon nitride (Si3N4) ceramic cutting tools with and without boride additive (2.5 vol% ZrB2 or TiB2) prepared by hot‐pressing at 1500°C were investigated. Due to the α‐ to β‐Si3N4 phase transformation and low densification temperature, boride‐containing Si3N4 ceramics with high hardness and high toughness were obtained. The turning tests showed that the effective cutting lengths of the Si3N4–2.5 vol% TiB2 ceramic (∼2480 m) and Si3N4–2.5 vol% ZrB2 ceramic (∼2200 m) were higher than the monolithic Si3N4 ceramic (∼1780 m). As the toughness was improved while maintaining relative high hardness, the cutting performances of the boride‐containing Si3N4‐based inserts were improved by adding 2.5 vol% ZrB2 or TiB2. The improved cutting performance indicated that the boride‐containing Si3N4 ceramics are expected to be used in the field of ceramic cutting tools.
Une réalité en noir et blanc, ou en plusieurs nuances de gris? La segmentation juridique et son effet sur la segmentation du marché du travail en Europe
Authors: DINGELDEY Irene , GERLITZ Jean‐Yves 
Published: November 2022

RésuméLes auteurs examinent l'effet du droit du travail sur la segmentation du marché du travail effective dans 22 pays européens entre 1991 et 2014. Après avoir isolé trois fonctions protectrices du droit du travail (fonctions régulatrice, hiérarchisante et compensatrice), ils associent statistiques descriptives et analyse multivariée pour faire ressortir l'effet de chacune sur l'emploi typique et atypique global, masculin et féminin. Ils observent qu'une dimension hiérarchisante affirmée, associée à une forte fonction régulatrice, favorise l'emploi typique masculin et l'emploi atypique féminin. Une législation très compensatrice, en principe destinée à protéger les femmes et autres groupes moins bien insérés, favorise paradoxalement l'emploi atypique masculin.
