Environmental contamination is widespread and can negatively impact wildlife health. Some contaminants, including heavy metals, have immunosuppressive effects, but prior studies have rarely measured contamination and disease simultaneously, which limits our understanding of how contaminants and pathogens interact to influence wildlife health. Here, we measured mercury concentrations, influenza infection, influenza antibodies and body condition in 749 individuals from 11 species of wild ducks overwintering in California. We found that the odds of prior influenza infection increased more than fivefold across the observed range of blood mercury concentrations, while accounting for species, age, sex and date. Influenza infection prevalence was also higher in species with higher average mercury concentrations. We detected no relationship between influenza infection and body fat content. This positive relationship between influenza prevalence and mercury concentrations in migratory waterfowl suggests that immunotoxic effects of mercury contamination could promote the spread of avian influenza along migratory flyways, especially if influenza has minimal effects on bird health and mobility. More generally, these results show that the effects of environmental contamination could extend beyond the geographical area of contamination itself by altering the prevalence of infectious diseases in highly mobile hosts.

Current organ-on-a-chip (OoC) systems mimic important aspects of specific organ and tissue functions, however, many commercial and academic devices are either too simple for advanced assays or require a complicated support set-up including external driving systems such as pumps and tubing that hamper scalability and robustness.

We have developed a novel, pump-less directional flow recirculating organ-on-a-chip (rOoC) platform that creates continuous or pulsed directional gravity-driven flow by a combination of a 3D-tilting system and an optimized microfluidic layout.

The rOoC platform allows growing and connecting tissue or organ representations on-chip with the possibility of incorporating barrier functions, gradients, and circulating cells. Using the rOoC platform we demonstrate simple and reproducible endothelialisation, hepatic organoid integration, and the first steps of vascularization of 3D organ representations on-chip.

THOC6 is the genetic basis of autosomal recessive THOC6 Intellectual Disability Syndrome (TIDS). THOC6 facilitates the formation of the Transcription Export complex (TREX) tetramer, composed of four THO monomers. The TREX tetramer supports mammalian mRNA processing that is distinct from yeast TREX dimer functions. Human and mouse TIDS model systems allow novel THOC6-dependent TREX tetramer functions to be investigated. Biallelic loss-of-function (LOF) THOC6 variants do not influence the expression and localization of TREX members in human cells, but our data suggests reduced binding affinity of ALYREF. Impairment of TREX nuclear export functions were not detected in cells with biallelic THOC6 LOF. Instead, mRNA mis-splicing was observed in human and mouse neural tissue, revealing novel insights into THOC6-mediated TREX coordination of mRNA processing. We demonstrate that THOC6 is required for regulation of key signaling pathways in human corticogenesis that dictate the transition from proliferative to neurogenic divisions that may inform TIDS neuropathology.

Published: September 2022

Pyramidal tract neurons (PTNs) are fundamental elements for motor control. However, it is largely unknown if PTNs are segregated into different subtypes with distinct roles in movement performance. Using anatomical, electrophysiological and optogenetics tools, we analyzed in both sexes’ mice motor cortex, PTNs projecting to red and pontine midbrain nuclei, which are important hubs connecting cerebral cortex and cerebellum playing a critical role in the regulation of movement. We reveal that vast majority of M1 neurons projecting to the red and pontine nuclei constitutes different populations. Corticopontine neurons have higher conduction velocities and morphologically, a most homogeneous dendritic and spine distributions along cortical layers. Optogenetically inhibiting either kind projection, differentially affects forelimb movement onset and execution in a lever press task, but only the activity of corticopontine neurons is significantly correlated with trial-by-trial variations in reaction time. The results indicate that cortical neurons projecting to the red and pontine nuclei constitute distinct functional and anatomical pathways and they contribute differently to sensorimotor integration, suggesting that layer 5 output neurons are functionally compartmentalized generating, in parallel, different downstream coding.
Y-type quadrotor radar cross-section analysis
Authors: Zhou Zeyang , Huang Jun
Published: September 2022

Purpose

The purpose of his paper is to study the radar stealth performance of a Y-type quadrotor with coaxial rotors and parallel rotors.

Design/methodology/approach

This Y-type quadrotor is designed as an aerodynamic layout with parallel twin rotors at the front and coaxial twin rotors at the rear. The multi-rotor scattering (MRS) method based on multi-rotor dynamic simulation (MRDS) and electromagnetic scattering module (ESM) is presented. MRDS is used to simulate the complex rotation of parallel rotors and coaxial rotors. ESM is used to calculate the instantaneous radar cross-section (RCS) of the quadrotor.

Findings

For a single rotor, the minimum period of the RCS curve at a given azimuth is equal to the basic passage time of the blade, where increasing the speed can shorten this minimum period. When the elevation angle increases, the forward RCS fluctuation of the quadrotor increases, while the average RCS decreases. The change of the roll angle will affect both the mean and the maximum difference of the RCS–time curve at the given lateral azimuth. The increase of the pitch angle will enhance the dynamic amplitude of the RCS–time curve under the forward azimuth.

Practical implications

The research in this article can provide reference for the stealth design of the Y-type quadcopter in the future.

Originality/value

The originality is the establishment of the MRS method. This method could provide value for dealing with the electromagnetic scattering problem of coaxial rotors and parallel rotors.
Localized magnetic properties measurement of interlocking core laminations
Authors: Li Yongjian , Zhang Kai , Dou Yu , Lin Zhiwei , Fu Yu , Zhang Changgeng
Published: September 2022

Purpose

In rotational alternating current machines, interlocking is a commonly used manufacturing method to fix laminated silicon steel cores. The purpose of this study is to measure the localized magnetic properties more comprehensively and to analyze the deteriorated magnetic properties caused by interlocking more accurately.

Design/methodology/approach

A movable B–H sensor is designed in this paper. The localized magnetic properties measurement was performed to investigate the magnetic properties around the interlocks with various sizes, various orientations and various numbers of laminations. Then, the damaged area caused by the interlocking was quantified, and the magnetic degradation of different degrees is layered.

Findings

The measurement results have shown that the interlocks with larger sizes, along the transverse direction and on 10-layer laminate, will lead to more serious magnetic degradation, and the maximum loss increment can reach up to 70%.

Originality/value

This work is an improvement and optimization based on the previous overall magnetic measurement of the interlock. The quantitative results of the localized magnetic measurement will have a certain significance for the accurate modeling and simulation of the electrical machines and provide valuable guidance for the optimization of the actual production process of the motor.
Strategic deviance and trade credit
Authors: Damle Harshali , Sinha Rajesh Kumar
Published: September 2022

Purpose

Literature sparsely documents the association between the deviant behavior of a firm and its financial policies. Trade credit is one of the most critical financial policies of a firm. In this study, the authors examine the association between strategic deviance and trade credit.

Design/methodology/approach

The authors explore a strategy-based explanation for trade credit by examining whether strategic deviance affects trade credit using a sample of 33 countries from 1996 to 2020. The authors test the hypothesis using static OLS regression models. To address autocorrelation and endogeneity issues, the authors use dynamic OLS models, lag models, and instrumental variable approach.

Findings

The authors find that an increase in strategic deviance reduces both demand and supply of trade credit, and the study’s results indicate that a one standard deviation increase in strategic deviance leads to a 1.34% decrease in the demand for trade credit. Also, a one standard deviation increase in strategic deviance leads to a 2.26% fall in the supply of trade credit.

Practical implications

This study facilitates managers to formulate trade credit policies when choosing a deviant strategy.

Originality/value

To the best of the authors’ knowledge, this is the first study to explore the association between strategic deviance and trade credit policies.
International evidence on the relationship between corporate ethics and dividend policy
Authors: Farooq Omar , Ahmed Neveen
Published: September 2022

Purpose

This paper aims is to document the relationship between corporate ethics prevailing in the country and the dividend policies adopted by firms.

Design/methodology/approach

The paper uses the data of non-financial firms from 61 countries to test the arguments presented in this paper. The data cover the period between 2010 and 2017.

Findings

This paper shows that dividend policies adopted by firms are sensitive to corporate ethics prevailing in the country. The firms headquartered in countries with relatively strong corporate ethics are less likely to pay dividends than firms headquartered in countries with relatively weak corporate ethics. These findings are robust across various proxies of dividend policy and across various estimation procedures. The paper, however, also shows that the relationship between corporate ethics and dividend policies is confined only to countries with strong institutional environment. This relationship breaks down in countries with weak institutional environment. Lastly, the paper shows that the value of dividend policy is more pronounced in countries with relatively weak corporate ethics.

Originality/value

Unlike the attempts to relate firm-level ethics and dividend policy, this paper focuses on the relationship between country-level indicator of corporate ethics and dividend policies. The benefit of using the country-level indicator of corporate ethics is that it highlights the general attitude of corporations with respect to ethics.
Research on wear performance of new type CL60 steel for metro wheel
Authors: Yidong Xie , Peiweni Sun , Qiang Li , Caozheng Fu , Zhu AiHua , Yang Jianwei , Ma Chaochao
Published: September 2022

Purpose

The CL60 steel wheels of metro vehicles running on a specific line need frequent reprofiling due to rapid wear. Considering this problem, a new material for metro wheels was designed. The friction and wear properties of the new material were studied, to reduce the wear rate and extend the service life of metro wheels.

Design/methodology/approach

Wheel specimens made of the two steel materials were tested using a GPM-60 wear tester under laboratory conditions. A field test was conducted on a specific metro line to track the wear in wheels made of the new material and CL60 steel wheels.

Findings

Under the laboratory conditions, the wear loss in the new material was 24.44% lower than that in CL60 steel. The field test revealed that compared to CL60 steel wheels, the new CL60 steel wheels showed a 19.42% decrease in tread wear on average. The field measurements for the wheels made of the new material are consistent with the results of laboratory simulation, suggesting relatively high wear resistance of the new material.

Practical implications

The results of the study can provide guidance on how to properly select steel material for metro wheels to avoid rapid wear and frequent reprofiling and reduce operating costs.

Originality/value

A new material for metro wheels was designed and developed by optimizing the content of Cr, Si, Mn, V and other elements. This material proved to have better wear resistance in both laboratory and field testing.

Design/methodology/approach

This paper uses descriptive and comparative methodology between the ethical aspects specific to natural procreation and artificial reproduction.

Findings

Religious beliefs play a significant role in shaping the moral perspective when an infertile couple is confronted with the choice between natural procreation and artificial reproduction.

Originality/value

This paper survey a broad bibliography and offers a critical evaluation of the moral aspects specific to different methods of reproductive technologies compared to the natural procreation approach.
Price and cooperation decisions in a cooperative R&D supply chain with different licensing models
Authors: Yan Fei , Chen Hong-Zhuan , Zhang Zhichao
Published: September 2022

Purpose

Industry practice has shown that technology licensing has an important effect on the R&D cooperation between firms. Different licensing methods will significantly impact a supply chain member's cooperative and price R&D decisions. However, there is scant literature investigating the decision on technology licensing and its impact on a supply chain member's price and cooperative R&D decisions. To address this gap, the authors investigate the R&D cooperation and the technology licensing in a supply chain formed of an original equipment manufacturer (OEM), a contract manufacturer (CM), and a third-party manufacturer which will compete with the OEM when the technology licensing occurs.

Design/methodology/approach

The authors investigate two licensing patterns, royalty licensing, fixed fee licensing together with the no licensing, within the R&D cooperative supply chain by developing two three-stage and a two-stage Stackelberg models.

Findings

Compare to the no licensing strategy, technology licensing always benefits to the OEM and the society especially when the technology efficiency and the brand power of the third-party manufacturer are more significant; the royalty licensing benefits to the OEM more when the technology efficiency and the brand power of the third-party manufacturer are higher; the fixed fee licensing benefits to the OEM more when the technology efficiency and the brand power of the third-party manufacturer are lower.

Practical implications

The royalty licensing is more effective for mitigating price competition intensity and helping firms to maintain higher sales margins; the fixed fee licensing induces firms' lower sales margins but increases the firms' sales quantities; in most cases, the fixed fee licensing is optimal from the perspectives of consumer and society, however, the CM's investment intention to the R&D technology with the fixed fee licensing is lower.

Originality/value

So far, different licensing models under the R&D cooperation have not been investigated, and the authors propose two three-stage Stackelberg models with considering the competition caused by technology licensing under the R&D cooperation to deal with the cooperative R&D and technology licensing issues.
A sustainable framework development and assessment for enhancing the environmental performance of cold supply chain
Authors: Kumar Neeraj , Tyagi Mohit , Sachdeva Anish
Published: September 2022

Purpose

The current study aims to deliver a consolidated view of environmental sustainability in cold supply chain performance systems (CSCPS), incorporating theoretical and empirical analysis for improving environmental standards. For this purpose, this study firstly aims to explore and analyze the various crucial challenging factors for environmental sustainability in the cold supply chain (CSC). Secondly, it discovers the most effective sustainable strategies for improving the environmental sustainability of CSCPS.

Design/methodology/approach

The exploration of the crucial challenging factors and the proposed sustainable strategies have been done using a systematic literature review relevant to the sustainable performance of CSC. At the same time, semi-structured brainstorming sessions were conducted with the domain professionals having an industrial and academic background to finalize the strategies. Empirical analysis has been performed using an intuitionistic fuzzy (IF) based hybrid approach of SWARA and COPRAS methods.

Findings

The key findings of the study address that “higher energy consumption during refrigerated transportation and storage” is the most crucial challenge for environmental sustainability in CSC. In addition, “managerial refrain to profit decline due to sustainability implementation” is the second most crucial challenge that hinders the adoption of sustainable practices in CSCs. Meanwhile, the governmental attention to motivating organizations for green adoption and implementation of solar energy-driven refrigeration technologies are the two most important discoveries of the study that might help in improving CSC's environmental performance.

Research limitations/implications

From the implications side, the study enriches and extends the current literature content on CSC sustainability. In addition, it offers sound managerial implications by identifying the challenges that create threats among the management for sustainability adoption and suggesting the most suitable sustainable strategies, which may help the management to raise the environmental performance of their CSC. Besides having various important theoretical and managerial implications for the study, contemplation of only environmental sustainability traits as a broader perspective limits the scope of the study.

Originality/value

The study's main contribution is the exploration of the most crucial challenges imparting obstructions in sustainable development and sustainable strategies, which may get the interest of the CSC players, market leaders, and industrial and academic practitioners working in the domain of CSC sustainability. In addition, this study offers structured theoretical and empirical evidence for CSC's environmental sustainability, thus playing a bridging role between theoretical sustainability concepts and its practical implications in CSC industries.

Authors: Jurado-Zambrano Diego Armando , Velez-Ocampo Juan , López-Zapata Esteban
Published: September 2022

Purpose

The purpose of this paper is to identify and analyze the strategic decisions, especially those focused on smart governance, that have been implemented by the cities of Buenos Aires (Argentina), Medellín (Colombia) and Mexico City (Mexico) and how they have impacted the Sustainable Development Goals (SDGs).

Design/methodology/approach

Using a qualitative approach and a descriptive scope, this manuscript follows a multiple case study methodology that was primarily based on the analysis of archival records and documentation using pattern-matching and cross-case synthesis as analytical techniques.

Findings

Observed cities share three main characteristics when implementing smart governance strategies linked to SDG 16: technology-based solutions to solve recent and long-lasting societal problems; broad, diverse and active citizen participation; and a socio-technical approach toward smart governance and SDG 16.

Research limitations/implications

This paper points out the linkages between smart governance and SDGs in emerging markets’ smart cities. The findings of this study indicate the need to promote socio-technical approaches – rather than merely technical perspectives – to achieve SDG 16. Hence, citizen participation, open government and co-creation initiatives are key to the promotion of more inclusive and solid institutions.

Originality/value

The most important contribution of this study is to identify the strategic initiatives developed by three leading smart cities in Latin America from the smart governance point of view and their relationship with the SDGs, which is useful because it contributes to expanding our understanding of smart governance from practical experiences.

Authors: Tangestani Hadith , Ghaseminasab-Parizi Maryam , Mazloomi Seyed Mohammad , Shams Mesbah , Ahmadi Afsane , Fararouei Mohammad
Published: September 2022

Purpose

Osteoporosis is increasingly affecting the young female adults of the Iranian population. The role of nutrition and physical activity on bone mineral content (BMC) and bone mineral density (BMD) in young female students has not been fully examined. This study aims to assess the dietary intake of several nutrients, such as calcium, phosphorus and protein; serum concentrations of vitamin D; and physical activity and their relationship with BMC and BMD in young female students.

Design/methodology/approach

Three-day dietary intakes of 67 female students were measured via duplicate portion sampling (DPS) method. Calcium and phosphorus content of the food samples were determined using atomic absorption spectrophotometer. Protein intake was determined by Kjeldahl method. Serum 25(OH) D concentrations were measured using enzyme-linked immunosorbent assay. Lumbar spine and femoral neck BMD were measured using dual-energy X-ray absorptiometry (DEXA).

Findings

The mean ±SD dietary intake of protein, calcium and phosphorus was 58.8 ± 16.9 g/day, 388 ± 135 mg/day and 1884 ± 682 mg/day, respectively. Significant positive correlation was found between serum vitamin 25(OH) D concentrations and BMC of lumbar spine (r= 0.28,p= 0.016) and BMD of femoral neck (r= 0.29,p= 0.016). Moreover, the authors observed a significant positive correlation between physical activity and femoral neck BMC (r= 0.26,p= 0.03) and BMD (r= 0.28,p= 0.02). This study found no significant associations between dietary intakes of protein, calcium and phosphorus and bone density measurements.

Originality/value

In this study, the authors measured the dietary intake of protein, calcium and phosphorus using DPS method. This study highlights the role of physical activity and serum vitamin 25(OH) D concentrations in female students’ bone health.
Narcissists going above and beyond? The role of perceived negative inequity and self-enhancement motivation
Authors: Chou Shih Yung , Ramser Charles
Published: September 2022

Purpose

Utilizing a self-regulatory perspective, the authors examine how narcissism influences perceived negative inequity and the downstream effects on self-enhancement motivation and organizational citizenship behaviors (OCBs) over time.

Design/methodology/approach

A total of 689 useable three-wave panel data were obtained via Amazon Mechanical Turk during a three-month period. A latent growth curve modeling approach using EQS 6.4 for Windows was employed to test the hypothesized model.

Findings

Results illustrate that individuals with higher levels of narcissism perceive higher levels of perceived negative inequity and then form higher levels of self-enhancement motivation, which prompt more OCB directed toward the organization (OCBO) than OCB directed toward individuals (OCBI). When perceived negative inequity increases over time, narcissists experience a faster increase in self-enhancement motivation, which also leads to a faster increase in OCBO compared to the increase in OCBI.

Originality/value

Theoretically, this study provides theoretical and empirical insights into understanding the process through which narcissists' OCBs are motivated. Practically, this study offers several practical recommendations that help managers manage OCBs effectively in the organization.
Spectrophotometric studies on some new hydroxyl-azo dyes derived from 6-ethyl-4-hydroxyquinoline-2(1H)-one
Authors: Yahyazadeh Asieh , Moradi Rufchahi Enayatollah , Yousefi Hessamoddin , Golzar Poursadeghi Seyyedeh Maryam
Published: September 2022

Purpose

This paper aims to synthesize 6-ethyl-4-hydroxyquinolin-2(1H)-one as a new enol-type coupling component in the preparation of some 3-arylazo-4-hydroxyquinolin-2(1H)-one dyes and evaluate the solvent effects on their absorption in ultraviolet-visible spectra.

Design/methodology/approach

6-Ethyl-4-hydroxyquinolin-2(1H)-one was synthesized by thermal cyclocondensation reaction of N, N′-bis(4-ethylphenyl) malonamide at 130–140°C in polyphosphoric acid. This compound was then applied in the azo-coupling reaction with some aniline-based diazonium salts, so as to prepare seven new mono-heterocyclic azo dyes. The structures of the compounds were confirmed using mass spectroscopic technique. Fourier transform infra red (FT-IR) and 1H proton nuclear magnetic resonance (1H NMR) and carbon-13 nuclear magnetic resonance (13 C NMR) studies on the structure of the azo compounds revealed that they exist as two E- and Z-isomers of hydrazone tautomer both in solid and solution state. The effects of acid and base on the visible absorption spectra of the dyes were also evaluated and discussed.

Findings

Ultra violet-visible UV-vis absorption spectra of the dyes didn’t show significant variation by changing of solvents because of intramolecular H-bonding between proposed hydrazone forms and 2- and 4-keto functions in their structures. The spectra of the dyes were not sensitive to the addition of acid but were very sensitive to base.

Originality/value

The synthesized 3-arylazo-4-hydroxyquinolin-2(1H)-one dyes are new members in the 4-hydroxyquinolin-2(1H)-one azo dyes family, where very few details regarding the synthesis of such dyes are reported before in the literature. They are unique in terms of synthesis and spectral properties.
The volatility spillover effect of macroeconomic indicators and strategic commodities on inflation: evidence from India
Authors: Rastogi Shailesh , Kanoujiya Jagjeevan
Published: September 2022

Purpose

This study aims to analyze the volatility spillover effects of crude oil, gold price, interest rate (yield) and the exchange rate (USD (United States Dollar)/INR (Indian National Rupee)) on inflation volatility in India.

Design/methodology/approach

This study uses the multivariate Generalized Autoregressive Conditional Heteroscedasticity (GARCH) models (Baba, Engle, Kraft and Kroner [BEKK]-GARCH and dynamic conditional correlation [DCC]-GARCH) to examine the volatility spillover effect of macroeconomic indicators and strategic commodities on inflation in India. The monthly data are collected from January 2000 till December 2020 for the crude oil price, gold price, interest rate (5-year Indian bond yield), exchange rate (USD/INR) and inflation (wholesale price index [WPI] and consumer price index [CPI]).

Findings

In BEKK-GARCH, the results reveal that crude oil price volatility has a long time spillover effect on inflation (WPI). Furthermore, no significant short-term volatility effect exists from crude oil market to inflation (WPI). However, the short-term volatility effect exists from crude oil to inflation while considering CPI as inflation. Gold price volatility has a bidirectional and negative spillover effect on inflation in the case of WPI. However, there is no price volatility spillover effect from gold to inflation in the case of CPI. The price volatility in the exchange rate also has a negative spillover effect on inflation (but only on CPI). Furthermore, volatility of interest rates has no spillover effect on inflation in WPI or CPI. In DCC-GARCH, a short-term volatility impact from all four macroeconomic indicators to inflation is found. Only crude oil and exchange rate have long-term volatility effect on inflation (CPI).

Practical implications

In an economy, inflation management is an essential task. The findings of the current study can be beneficial in this endeavor. The knowledge of the volatility spillover effect of all the four markets undertaken in the study can be significantly helpful in inflation management, especially for inflation-targeting policy.

Originality/value

It is observed that no other study has addressed this issue. We do not find any other research which studies the volatility spillover effect of gold, crude oil, interest rate and exchange rate on the inflation volatility. The current study is novel with a significant contribution to the vast knowledge in this context.
Advertising activism and social resistance: a case study of a bottom-up advertising campaign in Hong Kong
Authors: Chan Chi Kit , Yuen Anna Wai Yee
Published: September 2022

Purpose

This study scrutinizes the convergence between commercial advertising and the political vision of social movement in media advertisements. This study deliberates how commercial advertisement could be compatible with movement discourses and social resistance. Such hybridization between commercial narration and movement discourses is different from political advertising sponsored by political and civic organizations. This study uses an advertising campaign in Hong Kong which expressed outcry against police search on an outspoken media as a case study to conceptualize advertising activism with the thematic analysis of the movement discourses shown in printed advertisements. This study aims to engage with scholarly dialogue surrounding social movement studies and discuss how movement discourses could hybridize with commercial advertisement.

Design/methodology/approach

This study examines the discourses and textual features of an advertising campaign initiated by the public instead of political elites and social movement organizations in Hong Kong, in which various individual citizens, anonymous participants, business enterprises and civic organizations expressed their anger over a police search against an outspoken media (Apple Daily) by Hong Kong police. This bottom-up advertising campaign shows how the narration of commercial advertising could be hybridized with the activism for social resistance, which is conceptualized as advertising activism in this paper.

Findings

Based on the textual features and discourses embedded in the advertisements, this study investigates the printed advertisements mushroomed in Apple Daily since the police search in August 2020 by the thematic analysis under the concept of advertising activism: frame construction, identities mobilization and decentered solidarity. Advertising activism differs from commercial and political advertising from two ways. Firstly, its advertisements are cosponsored by numerous nonpolitically well-known individuals or organizations. Secondly, advertising activism feature with hybridization between commercial narration and political or movement discourses. Discourses of advertising activism aim to mobilize the commercial identity of consumers for noncommercial means by their consumption behaviors.

Originality/value

The findings illustrate a hybridization of commercial narration and movement discourses stemming from social movement and identity politics, which is coined by our conceptualization of advertising activism. While commercial and political advertising focus on business promotion and political messages, respectively, advertising activism demonstrates multiple layers of cultural meanings on the consumption behaviors which hybridize with political and movement discourses. The authors hope this study could unleash further intellectual dialogue on the social role of advertising in social movement and how movement discourses “spillover” from social events to the commercial advertisement.
Health-care system in Jordan: challenges and solutions
Authors: Rababa Mohammad
Published: September 2022

Purpose

This study aims to explore the challenges in the Jordanian health-care system and the potential solutions for these challenges.

Design/methodology/approach

A narrative literature review was conducted.

Findings

The challenges of the health-care system in Jordan related to geriatric care are the new emergence of nursing homes; the limited health-care services and supplies; the growing aging population; the dramatic change in the family structure. There are many credible approaches used to solve those challenges, including social networking, advocacy, education and research, lobbying and financial support.

Originality/value

There is a lack of research studies examining the perceived barriers and facilitators of geriatric care in Jordan from the perspectives of health-care professionals, health-care managers and older adults themselves. Future intervention studies are recommended to target the challenges in the Jordanian health-care system concerning geriatric care.
Variation in abundance of trees originating from sapling banks facilitates the coexistence of two Abies species in a wave‐regenerated forest
Authors: Suzuki Satoshi N. , Kachi Naoki , Suzuki Jun‐Ichirou
Published: September 2022

The contribution of sapling banks to the coexistence of species with different shade tolerance under the “wave regeneration” regime has not been researched extensively. This study first assessed spatial and temporal variations in the relative dominance of two Abies species, Abies veitchii and Abies mariesii, with different shade tolerance in a wave‐regenerated forest. Second, we present the age structure and its spatial variation in young Abies stands (sapling stage) to exhibit the prevalence and variability of regeneration from sapling banks (defined as trees established 10 years before canopy opening). The relative dominance of A. mariesii, the more shade‐tolerant species, compared to that of A. veitchii, did not change over a period of 10 years, irrespective of stand developmental stages, indicating the importance of initial dominance in determining the local species composition. The tree ages at the sapling stage were significantly higher for A. mariesii than for A. veitchii. Approximately, 30% of all trees were likely to arise from a sapling bank, and 86% of them were A. mariesii. Age structure significantly varied between 5 × 5 m quadrats; some quadrats were dominated by A. mariesii originating from sapling banks, while others were dominated by A. veitchii that were established at the time of canopy opening. These results indicate that regeneration from sapling banks contributes to the dominance of A. mariesii and that the spatial variation in the abundance of trees originating from sapling banks is essential for the coexistence of A. mariesii with A. veitchii.
The educational task of the German vocational school (1958)
Authors: Spranger Eduard , Winch Christopher
Published: September 2022

This classic essay by Eduard Spranger (1882–1963) is here published for the first time in English, in a translation by Stephanie Wilde. In this contribution Spranger discusses and advocates the need for a vocational school that addresses the civic and individual needs of students as well as the vocational requirements of the nation. He emphasises personal growth, the need for self-knowledge in making a vocational choice and makes a point about the importance of the social role of occupations and the role that being part of a community plays in developing citizenship. He identifies that tasks of the vocational school as both to develop greater self-awareness and to lead young people into civic and vocational engagement. In doing this he acknowledges the influence of Georg Kerschensteiner on his own thought. Much turns in the discussion on differences between German and English expressions, and these are discussed in the complementary essay, ‘The Legitimation of School-based Bildung in the Context of Vocational Education and Training. The Legacy of Eduard Spranger’, by Philipp Gonon. An introduction to the broader context is provided in ‘Founding German Vocational Education: Kerschensteiner, Spranger and Fischer as key figures in the classical German VET Theory’ ‘…’ by Christian Steibe, Dina Kuhlee and Christopher Winch, the Editors of this Special Issue.
Feeding ‘Growing Boys’ and Nourishing ‘Handy English Lads’: British Prison Diets and the Reclamation of the Male Juvenile Offender, 1895–1908
Authors: Durbach Nadja
Published: September 2022

Between 1895 and 1908, Britain's prison administration introduced reforms aimed at ‘reclaiming’ male adolescent offenders. These included a significant rethinking of the dietary. Drawing on the sciences of nutrition and of adolescent development, the prison experimented with the rations for juvenile–adults, a new category of inmate defined by age and by gender. For the first time, the state explicitly used prison rations in the service of sovereignty: it sought to fashion working‐class male adolescents into well‐developed specimens of British manhood able to contribute to the increasingly democratic polity and to defend and populate the nation and its empire.

Insecticides are anthropogenic environmental stressors and also a common stressor for mosquito vectors. However, the use of insecticides is often guided by short‐term efficacy, and the sublethal effect on their target or nontarget species has long been ignored. Here, we analyzed how sublethal exposure of the promising vector‐control bioinsecticide spinetoram to Aedes aegypti larvae alter adult performance and susceptibility to dengue virus (DENV) infection. We found that the surviving adult mosquitoes were significantly smaller and exhibited weaker blood‐feeding capacity than control females, apart from the extended immature development period. In terms of reproductive potential, although the F0 generation produced a similar number of eggs and offspring during the first gonotrophic cycle, the survival rates of the F1 generations were significantly lower as compared to the control group, suggesting transgenerational sublethal effects on the F1 generation. Notably, surviving adult females had higher DENV‐2 viral loads than the control group after spinetoram sublethal exposure. Mechanistically, transcriptomic analysis showed that inhibition of oxidative phosphorylation may function in stimulating DENV production in adult Ae. aegypti. In Aag2 cells, significant accumulation of apoptosis, mitochondrial reactive oxygen species production, and DENV‐2 replication by spinetoram exposure consistently support our conclusion. Our study highlights the threat of sublethal spinetoram exposure on outbreaks of mosquito‐borne viruses.

Expressing heterologous antigens by plasmids may cause antibiotic resistance. Additionally, antigen expression via plasmids is unstable due to the loss of the plasmid. Here, we developed a balanced‐lethal system. The Listeria monocytogenes (LM) balanced‐lethal system has been previously used as an antigen carrier to induce cellular immune response. However, thus far, there has been no reports on Listeria ivanovii (LI) balanced‐lethal systems. The dal and dat genes from the LI‐attenuated LIΔatcAplcB (LIΔ) were deleted consecutively, resulting in a nutrient‐deficient LIΔdd strain. Subsequently, an antibiotic resistance‐free plasmid carrying the LM dal gene was transformed into the nutrient‐deficient strain to generate the LI balanced‐lethal system LIΔdd:dal. The resultant bacterial strain retains the ability to proliferate in phagocytic cells, as well as the ability to adhere and invade hepatocytes. Its genetic composition was stable, and compared to the parent strain, the balanced‐lethal system was substantially attenuated. In addition, LIΔdd:dal induced specific CD4+/CD8+ T‐cell responses and protected mice against LIΔ challenge. Similarly, we constructed an LM balanced‐lethal system LMΔdd:dal. Sequential immunization with different recombinant Listeria strains will significantly enhance the immunotherapeutic effect. Thus, LIΔdd:dal combined with LMΔdd:dal, or with other balanced‐lethal systems will be more promising alternative for vaccine development.
Learning to be Unbiased: Evidence from the French Asylum Office

What determines whether some asylum seekers are granted refugee status while others are rejected? I draw upon archival records from a representative sample of 4,141 asylum applications filed in France between 1976 and 2016 to provide new evidence on the determinants of asylum decisions. I find that applicants who are Christian (rather than Muslim) are more likely to be granted refugee status, controlling for all other individual characteristics available to the asylum officers making the decisions. However, linking archival records to detailed administrative data, I also show that bureaucrats at the French Asylum Office stop discriminating after about a year on the job. These findings have implications for strategies to curtail discrimination in courtrooms and administrations.
Reasons for qualitative psychologists to share human data
Authors: Karhulahti Veli‐Matti
Published: September 2022

Qualitative data sharing practices in psychology have not developed as rapidly as those in parallel quantitative domains. This is often explained by numerous epistemological, ethical and pragmatic issues concerning qualitative data types. In this article, I provide an alternative to the frequently expressed, often reasonable, concerns regarding the sharing of qualitative human data by highlighting three advantages of qualitative data sharing. I argue that sharing qualitative human data is not by default ‘less ethical’, ‘riskier’ and ‘impractical’ compared with quantitative data sharing, but in some cases more ethical, less risky and easier to manage for sharing because (1) informed consent can be discussed, negotiated and validated; (2) the shared data can be curated by special means; and (3) the privacy risks are mainly local instead of global. I hope this alternative perspective further encourages qualitative psychologists to share their data when it is epistemologically, ethically and pragmatically possible.

Objectives

To investigate whether patients with suspected pelvic lymph node metastases (molecular imaging [mi] N1) on staging prostate‐specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) had a different oncological outcome compared to those in whom the PSMA PET/CT did not reveal any pelvic lymph node metastases (miN0).

Patients and Methods

All patients with pelvic lymph node metastatic (pN1) disease after robot‐assisted radical prostatectomy (RARP) and extended pelvic lymph node dissection (ePLND) between January 2017 and December 2020 were included. To assess predictors of biochemical progression of disease after RARP, a multivariable Cox regression analysis was performed, including number of tumour‐positive lymph nodes, diameter of the largest nodal metastasis, and extranodal extension.

Results

In total, 145 patients were diagnosed with pN1 disease after ePLND. The median biochemical progression‐free survival in patients with miN0 on PSMA PET/CT was 13.7 months, compared to 7.9 months in patients with miN1 disease (P = 0.006). On multivariable Cox regression analysis, both number of tumour‐positive lymph nodes (>2 vs 1–2: hazard ratio [HR] 1.97; P = 0.005) and diameter of the largest nodal metastasis (HR 1.12; P < 0.001) were significant independent predictors of biochemical progression of disease.

Conclusion

Patients in whom pelvic lymph node metastases were suspected on preoperative PSMA imaging (miN1), patients diagnosed with >2 tumour‐positive lymph nodes, and patients with a larger diameter of the largest nodal metastasis had a significantly increased risk of biochemical disease progression after surgery.
