Assessment of
ϒ
-states above
BB¯
-threshold using a constituent-quark-model based meson-meson coupled-channels framework
Authors: Ortega P. G. , Entem D. R. , Fernández F. , Segovia J.
Published: June 2024

The ϒ(10753) state has been recently observed by the Belle and Belle II collaborations with enough global significance to motivate an assessment of the high-energy spectrum usually predicted by any reasonable quark model. In the framework of a constituent quark model which satisfactorily describes a wide range of properties of conventional hadrons containing heavy quarks, the quark-antiquark and meson-meson degrees of freedom have been incorporated with the goal of elucidating the influence of open-bottom meson-meson thresholds into the ϒ states whose masses are within the energy range of the ϒ(10753)’s mass. It is well known that such effects could be relevant enough as to dynamically generate new states and thus provide a plausible explanation of the nature of the ϒ(10753) state. In particular, we have performed a coupled-channels calculation in which the bare states ϒ(4S), ϒ(3D), ϒ(5S), and ϒ(4D) are considered together with the threshold channels BB¯, BB¯*, B*B¯*, BsB¯s, BsB¯s*, and Bs*B¯s*. Among the results we have described, the following are of particular interest: (i) a richer complex spectrum is gained when thresholds are present and bare bound states are sufficiently nonrelativistic; (ii) those poles obtained in the complex energy plane do not have to appear as simple peaks in the relevant cross sections; and (iii) the ϒ(10753) candidate is interpreted as a dressed hadronic resonance whose structure is an equally mixture of a conventional bb¯ state and B*B¯* molecule.

Authors: Centelles Chuliá Salvador , Miranda O. G. , Valle Jose W. F.
Published: June 2024

Precision measurements of neutrino-electron scattering may provide a viable way to test the nonminimal form of the charged and neutral current weak interactions within a hypothetical near-detector setup for the Deep Underground Neutrino Experiment (DUNE). Although low-statistics, these processes are clean and provide information complementing the results derived from oscillation studies. They could shed light on the scale of neutrino mass generation in low-scale seesaw schemes.

Realtime dynamics of hyperon spin correlations from string fragmentation in a deformed four-flavor Schwinger model
Authors: Barata João , Gong Wenjie , Venugopalan Raju
Published: June 2024

Self-polarizing weak decays of Λ-hyperons provide unique insight into the role of entanglement in the fragmentation of QCD strings through measurements of the spin correlations of ΛΛ¯ pairs produced in collider experiments. The simplest quantum field theory representing the underlying parton dynamics is the four-flavor massive Schwinger model plus an effective spin-flip term, where the flavors are mapped to light (up or down) and heavy (strange) quarks and their spins. This construction provides a novel way to explore hyperon spin correlations in 1+1 dimensions. We investigate the evolution of these correlations for different string configurations that are sensitive to the rich structure of the model Hamiltonian.

Electric corrections to
π−π
scattering lengths in the linear sigma model
Authors: Cádiz R. , Loewe M. , Zamora R.
Published: June 2024

In this article, we analyze the role of an external electric field, in the weak field approximation, on π−π scattering lengths. The discussion is presented in the frame of the linear sigma model. To achieve this, we take into account all one-loop corrections in the s, t, and u channels associated with the insertion of a Schwinger propagator for charged pions, focusing on the region characterized by small values of the electric field. Furthermore, one of the novelties of our work is the explicit calculation of box diagrams, which were previously overlooked in discussions regarding magnetic corrections. It turns out that the electric field corrections have an opposite effect with respect to magnetic corrections calculated previously in the literature.

BPZ equations for higher degenerate fields and nonperturbative Dyson-Schwinger equations
Authors: Jeong Saebyeok , Zhang Xinyu
Published: June 2024

In the two-dimensional Liouville conformal field theory, correlation functions involving a degenerate field satisfy partial differential equations due to the decoupling of the null descendant field. On the other hand, the instanton partition function of a four-dimensional N=2 supersymmetric theory in the Ω-background at a special point of the parameter space also satisfies a partial differential equation resulting from the constraints of the gauge field configurations. This partial differential equation can be proved using the nonperturbative Dyson-Schwinger equations. We show for the next-to-simplest case that the partial differential equations obtained from two different perspectives can be identified, thereby confirming an assertion of the Bogomol’nyi-Prasad-Sommerfield/conformal field theory correspondence.

Electroweak Corrections to Double Higgs Production at the LHC
Authors: Bi Huan-Yu , Huang Li-Hong , Huang Rui-Jun , Ma Yan-Qing , Yu Huai-Min
Published: June 2024

We present the results for the complete next-to-leading order electroweak corrections to pp→HH at the Large Hadron Collider, focusing on the dominant gluon-gluon fusion process. While the corrections at the total cross-section level are approximately −4%, those near the energy of HH production threshold exceed +15%, and corrections at the high-energy region are around −10%, leading to a shape distortion for the differential distributions. Our findings substantially diminish the theoretical uncertainties associated with this pivotal process, providing valuable input for understanding the shape of the Higgs boson potential upon comparison with experimental measurements.

(4-Butyl-1-ethyl-1,2,4-triazol-5-ylidene)[(1,2,5,6-η)-cycloocta-1,5-diene](triphenylphosphane)iridium(I) tetrafluoridoborate
Authors: Lerch Timothy G. , Gau Michael , Albert Daniel R. , Rajaseelan Edward
Published: June 2024

The title compound, [Ir(C8H12)(C8H15N3)(C18H15P)]BF4, a new triazole-based N-heterocyclic carbene iridium(I) cationic complex with a tetrafluoridoborate counter-anion, crystallizes with two cations and two anions in the asymmetric unit of space group Pc. The Ir centers of the cations have distorted square-planar conformations, formed by a bidentate (η2 + η2) cycloocta-1,5-diene (COD) ligand, an N-heterocyclic carbene and a triphenylphosphane ligand with the NHC carbon atom and P atom being cis. In the extended structure, non-classical C–H...F hydrogen bonds, one of which is notably short (H...F = 2.21 Å), link the cations and anions. The carbon atoms of one of the COD ligands are disordered over adjacent sites in a 0.62:0.38 ratio.
Is Sub-Saharan Africa ready to serve as an alternative apparel-sourcing destination to Asia for US Fashion companies? A product-level analysis
Authors: Lu Sheng
Published: June 2024

Purpose

The prospect of Sub-Saharan Africa (SSA) as an apparel-sourcing base for US fashion companies has been a growing heated debate among academia, industry practitioners and policymakers. This study aims to evaluate SSA countries’ readiness to serve as an alternative sourcing destination to Asia for US fashion companies, focusing on comparing the similarities and differences of US apparel imports from these two regions at the product level.

Design/methodology/approach

This study was based on a statistical analysis of detailed product features and assortment information of thousands of apparel items at the stock-keeping unit level sold by US retailers between January 2021 and December 2023.

Findings

US fashion companies seemed to leverage SSA countries as suppliers of “niche products,” such as those relatively simple and basic apparel categories containing African cultural elements and targeting the luxury and premium market segment. However, the range of apparel products available for US fashion companies to source from the SSA region remained significantly more limited than those from Asia. Also, US apparel imports from SSA countries were primarily made of cotton and polyester, with less use of other fiber types, including nylon, rayon, viscose, wool and those made from recycled textile materials.

Originality/value

The study’s findings provided fresh insights into why US fashion companies sourced from SSA countries and the specific types of products they were sourcing, going beyond existing studies based on macro trade statistics. The results also deepened the understanding of SSA countries’ competitiveness as an apparel-sourcing destination and their potential to serve as an alternative to sourcing from Asia, particularly from a unique product perspective.
How and for whom abusive supervision influences organizational citizenship behavior: the roles of burnout and workplace friendship
Authors: Gümüştaş Cihangir , Karataş Gümüştaş Nilgün
Published: June 2024

Purpose

Although many studies have investigated the link between abusive supervision and employee organizational citizenship behavior (OCB), most of them have been performed in isolation, resulting in inconsistent findings and a lack of a systematic structure for understanding how abusive supervision affects OCB. Building on the conservation of resources theory, this study aims to investigate the impact of abusive supervision on OCB through the mediating role of burnout. Additionally, the moderating influence of workplace friendship on the link between abusive supervision and burnout was examined.

Design/methodology/approach

We used data from a two-wave survey of 316 employees with a time interval of 4 weeks. We conducted a mediated moderation analysis to test our model using PROCESS (Hayes, 2013), a statistical macro for SPSS, to examine moderated mediation models' direct and indirect effects.

Findings

The findings revealed that burnout completely mediated the association between abusive supervision and OCB. Additionally, workplace friendships strengthen employees' social networks, providing them with increased resources and support when facing abusive supervision compared to those lacking such friendships. The results have both theoretical and practical implications, which are discussed.

Originality/value

First, this study examined the moderating role of workplace friendship and the mediating role of burnout in the relationship between abusive supervision and OCB. This is a novel contribution to the literature, as previous research has not examined these factors. Previous research has shown that abusive supervision can lead to decreased effort, but the mechanisms that affect job performance have attracted relatively little attention.
Navigating gender and culture in constructing network ties: perceptions and behaviors of women founders in Jordanian digital businesses
Authors: Alakaleek Wejdan , Cooper Sarah Yvonne , Orser Barbara , Harrison Richard
Published: June 2024

Purpose

This study sought to examine how women founders navigate gender and cultural influences in constructing network ties in Jordan.

Design/methodology/approach

In-depth interviews document the experiences of 14 women founders operating digital technology-based businesses in Amman, Jordan.

Findings

Gender homogenous ties were perceived to be of diminished quality, limiting the ability of the women founders to acquire resources while risking isolation from diverse networks. Formal professional, male-centric ties were perceived to offer more business impact due to the applicability and usefulness of information. Formal communication, use of intermediaries and industry events were used to develop network ties. These approaches enable founders to respect gendered collectivist norms, such as adhering to family members’ expectations about occupational roles, while meeting new business associates. The strength of network ties emerged as a continuum with strong, weak and midpoint ties. Midpoint ties offered valued encouragement and emotional support but were perceived to be less effective and provided fewer resources compared to strong network ties.

Originality/value

Mechanisms of gender inequality are evidenced in how gender, culture and social networks operate in relation to each other. Perceptions reflect culturally situated, within-group stereotypes, informing how women founders discount other women’s knowledge and experience.
Building sustainable performance through green supply chain management
Authors: El Mokadem Mohamed , Khalaf Magdy
Published: June 2024

Purpose

The aim of this research is to examine the relationship between green supply chain management and sustainability performance in a manufacturing context.

Design/methodology/approach

A survey approach was adopted to collect data from 163 manufacturing organizations to test the research hypotheses. A structural equation modeling (SEM) using the technique of path analysis with bootstrapping is used to test the hypothesized relationships.

Findings

The research findings provide supporting evidence for the importance of implementing green supply chain management (GSCM) as a holistic system that includes internal and external green practices. Besides, the findings highlight the direct effect of GSCM on environmental, social and operational performance. Finally, the findings provide supporting evidence that GSCM could only be translated into better economic returns through the improvement of environmental and operational performance.

Research limitations/implications

The nature of the surveyed sample and the use of a single informant might limit the ability to generalize the research findings outside the research context.

Practical implications

The research findings help managers understand that GSCM must be implemented as a holistic system and that the real benefits of its implementation extend beyond the mere environmental benefits to include operational, social as well as economic benefits.

Originality/value

The paper’s contribution to knowledge is twofold. First, the study identifies how GSCM is conceptualized and how its effect is translated into improved economic performance. Second, the research explains the contradicting findings in previous studies regarding the relationship between GSCM and economic performance.
Exploring the effects of quality signals on search advertising performance: the moderating role of keyword attributes
Authors: Li Xinjian , Zhang Yu , Wang Juan , Li Xiaoling
Published: June 2024

Purpose

In online exchange platforms' sponsored search advertising, the array of product quality signals within a keyword search results list plays a crucial role in shaping buyers' purchasing decisions. This research seeks to explore the impact of various quality signals – namely, ranking position, seller reputation and product price – on ad clicks. Additionally, it examines the role of keyword attributes, such as specificity and popularity, in modulating the effects of these quality signals on advertising clicks.

Design/methodology/approach

A total of 5,763 effective data points were collected from a leading B2B electronic platform company, and we employed negative binomial regression with Heckman correction methods to test the hypotheses.

Findings

The results indicate that in online exchange platforms, search ad clicks are significantly and positively affected by displayed signals such as ranking position, seller reputation and product price information. Notably, a U-shaped relationship emerges between product price and ad clicks. Furthermore, keyword specificity and popularity distinctly moderate the impact of these displayed signals on ad clicks within online exchange platforms.

Originality/value

This paper addresses the gap in existing research on search advertising by methodically analyzing the impact of various signals displayed in search results and how keyword attributes moderate ad clicks, all through a signaling theory lens.

Authors: Glover Wiljeana Jackson , Jacques Sabrina JeanPierre , Obounou Rebecca Rosemé , Barthélemy Ernest , Richard Wilnick
Published: June 2024

Purpose

This study examines innovation configurations (i.e. sets of product/service, social and business model innovations) and configuration linkages (i.e. factors that help to combine innovations) across six organizations as contingent upon organizational structure.

Design/methodology/approach

Using semi-structured interviews and available public information, qualitative data were collected and examined using content analysis to characterize innovation configurations and linkages in three local/private organizations and three foreign-led/public-private partnerships in Repiblik Ayiti (Haiti).

Findings

Organizations tend to combine product/service, social, and business model innovations simultaneously in locally founded private organizations and sequentially in foreign-based public-private partnerships. Linkages for simultaneous combination include limited external support, determined autonomy and shifting from a “beneficiary mindset,” and financial need identification. Sequential combination linkages include social need identification, community connections and flexibility.

Research limitations/implications

The generalizability of our findings for this qualitative study is subject to additional quantitative studies to empirically test the suggested factors and to examine other health care organizations and countries.

Practical implications

Locally led private organizations in low- and middle-income settings may benefit from considering how their innovations are in service to one another as they may have limited resources. Foreign based public-private partnerships may benefit from pacing their efforts alongside a broader set of stakeholders and ecosystem partners.

Originality/value

This study is the first, to our knowledge, to examine how organizations combine sets of innovations, i.e. innovation configurations, in a healthcare setting and the first of any setting to examine innovation configuration linkages.

Leadership communication behaviors and attachment styles: theory for educating leaders to meet communication challenges
Authors: London Manuel , Zobrist Christopher
Published: June 2024

Purpose

This conceptual article provides a basis for designing leader development programs that assess and train leaders to recognize demands for communication and how their personality affects the ways they transmit information, influence others and form positive relationships.

Design/methodology/approach

Adult attachment theory, Big Five personality dimensions (extraversion, conscientiousness, agreeableness, openness to experience and neuroticism) and pro-social and social sensitivity personality traits are proposed to shape the extent to which leaders enact relational, transmission and manipulative models of communication. These personality dimensions and communication models are the basis for assessment and training leaders to use in-person and various electronic media in ways that promote listeners’ attention, understanding and psychological safety.

Findings

Secure attachment leaders who are extraverted, prosocial and socially sensitive are proposed to use high touch media to communicate in ways that establish positive relationships. Avoidant and anxious attachment leaders use low-touch media that are manipulative or mitigate accountability.

Practical implications

The behaviors associated with transmitting information, influencing others and forming relationships can be a basis for assessing leaders’ attachment styles. Leaders can learn to diagnose situations to determine the best mixes of communication models to meet the demands of the situation.

Originality/value

Leaders who are promoted to higher levels of responsibility need to learn how to communicate with multiple stakeholders often during times of challenge and stress. How they communicate is likely to be a function of their comfort with interpersonal relationships, which in turn affects their use of personal and impersonal media.
Editorial: Stop saying “vulnerable consumers/customers”!
Authors: Russell-Bennett Rebekah , Bedggood Rowan , Raciti Maria M.
Published: June 2024

Purpose

The purpose of this editorial is to call out the practice of using identity-first language and labelling consumers and customers, describing them as “vulnerable” and offers practical strategies for person-first language of consumers/customers experiencing vulnerability.

Design/methodology/approach

The authors use Australian Indigenous and Indigenous women’s standpoint theory to reflect on their own use of terminology in the field of consumer/customer vulnerability and use their personal experiences to offer a series of practical strategies.

Findings

The authors propose six motivations for the use of person-first language in the field of consumer/customer vulnerability: easy to use, an English language convention, common practice, easy to measure, unintentional ignorance and an “us vs them” mindset.

Originality/value

To the best of the authors’ knowledge, this paper is the first to call out the practice of using identity-first language in the consumer/customer vulnerability field and offer practical strategies to enable person-first language.

Published: June 2024

Purpose

This paper analyzes knowledge-oriented leadership (KOL) and its impact on the learning achieved by the members of academic research teams. We study the influence of KOL on learning, both directly and indirectly, through the knowledge sharing that takes place within the team.

Design/methodology/approach

For this purpose, we conducted a survey of 477 researchers belonging to academic research teams. Through partial least squares structural equation modeling (PLS-SEM), our findings show that KOL positively affects both knowledge sharing and learning and that knowledge sharing also enhances learning.

Findings

Our results reveal the existence of a direct and indirect effect of KOL on learning, both significant and in the same positive direction, with a complementary partial mediation of knowledge sharing.

Research limitations/implications

This paper contributes to the literature in that it provides evidence in the academic context of how team leader behavior can influence knowledge sharing and learning.

Originality/value

This is one of the fewer studies that analyzed KOL on academic research teams and the first contribution that empirically shows how the effect of KOL on learning takes place.
Childhood adversity and severity of positive symptoms as predictors of suicidality controlling for sociodemographics among hospitalized patients diagnosed with schizophrenia in Jordan
Authors: Aldaieflih Mo’tasem M. , Haddad Rabia H. , Hamdan-Mansour Ayman M.
Published: June 2024

Purpose

This study aims to examine the predictive power of childhood adversity and severity of positive symptoms on suicidality, controlling for selected sociodemographics factors, among hospitalized patients diagnosed with schizophrenia in Jordan.

Design/methodology/approach

This study used a descriptive-explorative design. The study was conducted at two major psychiatric hospitals in Jordan. The targeted sample was 66 patients diagnosed with schizophrenia. Data was collected using a structured format in the period February–April 2024.

Findings

A two-step multiple hierarchical regression analysis was conducted. In the first model, childhood adversity and the severity of positive symptoms were entered. In the second model, sociodemographic variables were entered. The analysis revealed that the first model (F = 5.35, p = 0.007) was statistically significant. The second model (F = 717, p < 0.001) was statistically significant. Furthermore, the analysis revealed that childhood adversity was not a significant predictor for suicidality. However, positive symptoms and patients’ demographics (age, number of hospitalizations and length of being diagnosed with schizophrenia) were significant predictors of suicidality. The analysis revealed that childhood adversity was not a significant predictor of suicidality. However, positive symptoms and patients’ demographics (age, number of hospitalizations and length of being diagnosed with schizophrenia) were significant predictors of suicidality.

Research limitations/implications

One limitation of this study is related to the sample and the setting where there were only 66 patients recruited from governmental hospitals within inpatient wards. Thus, the upcoming studies should include more participants from private hospitals and different hospital settings including outpatient and emergency departments.

Practical implications

The research provides empirical insights that positive symptoms, age hospitalization and schizophrenia diagnosis length were significant predictors of suicidality. At the same time, childhood adversity was not a significant predictor of suicidality.

Social implications

The current research contributes to expanding mental health studies. Moreover, this study enlarges the body of knowledge in the academic world and clinical settings. It supports the disciplines of psychology, mental health and social sciences by increasing knowledge of the complicated relationships among childhood adversity, positive symptoms and suicidality.

Originality/value

This paper fulfills an identified need to study childhood adversity with comorbid psychiatric disorders such as schizophrenia, as well as psychiatric mental health covariates.

Authors: Hajilee Massomeh , Niroomand Farhang , Hayes Linda A.
Published: June 2024

In the field of international finance, there is a large role for international financial market integration and financial depth by contributing to the global financial system and enhancing financial system power through easier access to sufficient funds of government and private sectors. This research aims to determine the short‐run and long‐run impact of financial depth on international financial market integration in eight selected countries over the period of 1980–2021 in both a linear and nonlinear model, while providing the opportunity to assess the asymmetric impact of financial depth on international financial market integration. After estimating the models, we show that financial depth has significant short‐run and long‐run effects in most of our sample countries in the linear mode. We also show that the long‐run impact of financial depth on financial market integration is asymmetric in all eight countries, concluding that financial depth and risks associated with it play an important role in international financial market integration, and it is important for countries to select and implement adequate financial market policies to take advantage of this relationship.
Glutamine‐derived peptides: Current progress and future directions
Authors: Yu Tianfei , Hu Tianshuo , Na Kai , Zhang Li , Lu Shuang , Guo Xiaohua
Published: June 2024

Glutamine, the most abundant amino acid in the body, plays a critical role in preserving immune function, nitrogen balance, intestinal integrity, and resistance to infection. However, its limited solubility and instability present challenges for its use a functional nutrient. Consequently, there is a preference for utilizing glutamine‐derived peptides as an alternative to achieve enhanced functionality. This article aims to review the applications of glutamine monomers in clinical, sports, and enteral nutrition. It compares the functional effectiveness of monomers and glutamine‐derived peptides and provides a comprehensive assessment of glutamine‐derived peptides in terms of their classification, preparation, mechanism of absorption, and biological activity. Furthermore, this study explores the potential integration of artificial intelligence (AI)‐based peptidomics and synthetic biology in the de novo design and large‐scale production of these peptides. The findings reveal that glutamine‐derived peptides possess significant structure‐related bioactivities, with the smaller molecular weight fraction serving as the primary active ingredient. These peptides possess the ability to promote intestinal homeostasis, exert hypotensive and hypoglycemic effects, and display antioxidant properties. However, our understanding of the structure–function relationships of glutamine‐derived peptides remains largely exploratory at current stage. The combination of AI based peptidomics and synthetic biology presents an opportunity to explore the untapped resources of glutamine‐derived peptides as functional food ingredients. Additionally, the utilization and bioavailability of these peptides can be enhanced through the use of delivery systems in vivo. This review serves as a valuable reference for future investigations of and developments in the discovery, functional validation, and biomanufacturing of glutamine‐derived peptides in food science.
Real‐time quantitative detection of hydrocolloid adulteration in meat based on Swin Transformer and smartphone
Authors: Gao Zhenchang , Chen Shanshan , Huang Jinxian , Cai Honghao
Published: June 2024

Hydrocolloids are widely used in meat products as common food additives. However, research has indicated that excessive consumption of these hydrocolloids may have potential health implications. Currently, consumers mainly rely on sensory evaluation to identify hydrocolloid adulteration in meat products. Although many studies on quantitative detection of hydrocolloids have been conducted by biochemical methods in laboratory environments, there is currently a lack of effective tools for consumers and regulators to obtain real‐time and reliable information on hydrocolloid adulteration. To address this challenge, a smartphone‐based computer vision method was developed to quantitatively detect carrageenan adulteration in beef in this work. Specifically, Swin Transformer models, along with pre‐training and fine‐tuning techniques, were used to successfully automate the classification of beef into nine different levels of carrageenan adulteration, ranging from 0% to 20%. Among the tested models, Swin‐Tiny (Swin‐T) achieved the highest trade‐off performance, with a Top‐1 accuracy of 0.997, a detection speed of 3.2 ms, and a model size of 103.45 Mb. Compared to computer vision, the electrochemical impedance spectroscopy achieved a lower accuracy of 0.792 and required a constant temperature environment and a waiting time of around 30 min for data stabilization. In addition, Swin‐T model was also capable of distinguishing between different types of hydrocolloids with a Top‐1 accuracy of 0.975. This study provides consumers and regulators with a valuable tool to obtain real‐time quantitative information about meat adulteration anytime, anywhere.

Practical Application

This research provides a practical solution for regulators and consumers to non‐destructively and quantitatively detect the content and type of hydrocolloids in beef in real‐time using smartphones. This innovation has the potential to significantly reduce the costs associated with meat quality testing, such as the use of chemical reagents and expensive instruments.

Ohmic heating (OH) at different conditions (voltage: 15, 20, 25 V; frequency: 1, 5, 10 kHz) and one‐step water bath (WB) were used to heat wash and unwash surimi prepared from fresh pre‐rigor common carp. The optimal heating conditions were established through assessments of gel strength, Texture Profile Analysis (TPA), water‐holding capacity (WHC), whiteness, and sensory evaluation. Then, the impact of heating modes on gelation properties of unwashed surimi based on the optimal heating conditions was investigated. The study findings indicated a significant enhancement in gel properties compared to WB. Unwashed surimi gel properties showed improvement when derived from freshly caught raw fish and subjected to OH treatment. Moreover, variations in frequencies and voltages were observed to influence the heating rate. Optimal gel quality was achieved at 10 kHz 20 V (10 V/cm), facilitating swift progression through the gel deterioration stage, inhibition of protein hydrolyzing enzymes activity, and establishment of a stable gel network. Continuing to increase the heating rate would disrupt its network structure, resulting in diminished gel strength and WHC. The best quality of unwashed surimi gel was achieved by heating to 40°C for 30 min, followed by heating to 90°C for another 30 min (40°C 30 min + 90°C 30 min) under 10 kHz 20 V. The gel strength increased when held for 1 h at 40°C. For optimal heating efficiency, the heating mode of 40°C 30 min + 90°C 30 min is recommended to prepare unwashed surimi gel.

Practical Application

Ohmic heating, as a rapid food heat treatment method, can both increase the heating rate and improve the gelation properties of freshwater surimi. There is a wide range of potential applications for the heat treatment of the surimi.
China Slowdown Shocks, the West and Australia*
Authors: Tyers Rod , Zhou Yixiao
Published: June 2024

Western economies, including Australia, have benefited from several decades of extraordinary Chinese expansion. Yet, in recent years, slowing growth and demographic decline has diminished these gains, while geopolitical developments have further restricted growth‐driving commerce. Our purpose is to review key sources of recent contractionary changes within China and to assess their likely consequences for the West. Modelling scenarios emerge that see future economic losses in China and abroad, with the worst affected group being China's own low‐skill workers. Long‐term losses in the West are smaller but pervasive, with Australia's economic welfare per capita impaired most. Short‐term effects depend on China's monetary policy response, with a freeing up of China's exchange rate likely to minimise harm both in China and abroad.

Background

Australian Indigenous (AI) populations face significant socioeconomic disadvantage and have poorer health outcomes when compared to their non‐AI counterparts. There is a paucity of published literature on outcomes following hip fracture in the AI population.

Methods

We performed a retrospective cohort study comparing outcomes following hip fracture in AI and non‐ AI patients presenting to a single regional trauma centre. The primary outcome of interest was all‐cause mortality. Secondary outcomes of interest were the odds of postoperative delirium and length of stay in hospital. All outcomes were adjusted against collected baseline covariates.

Results

One hundred and twenty‐seven hip fractures were identified across 125 patients. There were 62 hip fractures in the AI group and 65 in the non‐AI group. The adjusted hazard ratio (HR) for all‐cause mortality was not statistically significant when comparing Indigenous versus non‐Indigenous patients (HR = 2.37, P = 0.055). Adjusted odds of postoperative delirium was lower in Indigenous patients (OR = 0.12; P = 0.018). The AI cohort had a 4 day longer median length of stay, which was not statistically significant when adjusted for covariates.

Conclusion

AI patients with hip fractures were younger, had a higher Charlson Comorbidity Index Score and American Society of Anaesthesiologists grade, as well as a higher incidence of diabetes and associated end‐organ sequalae. There was no difference in all‐cause mortality. Odds of postoperative delirium was lower in the AI group. We did not find any difference in the length of hospital stay.
School holidays and respiratory syncytial virus transmission in Sweden: An interrupted time series analysis

Aim

Respiratory syncytial virus (RSV) represents a significant cause of morbidity for children worldwide, especially for newborns. As RSV vaccines are not routinely used for children yet, non‐pharmaceutical interventions (NPIs) represent the main strategy for prevention. The objective of this study was to investigate the correlation between school holidays and RSV transmission.

Methods

Data were collected from the weekly reports on RSV incidence for the 2021/2022 and 2022/2023 seasons in Sweden. The 7‐day cumulative incidence of RSV was compared before and after the designated school holidays (Fall, Christmas, and Winter holidays).

Results

Our findings reveal an immediate (−1.7%, p < 0.001, 95% CI [−3.1%, −0.4%]) and gradual (−1.4%/week, p < 0.001, 95%CI [−1.8, −1.0]) reduction in RSV incidence following the Fall holiday in 2021, especially among children under 1 year of age, both immediately (−107.6%, p < 0.05, 95% CI [−203.7, −11.5]) and gradually afterwards (−58.5%/week, p < 0.001, 95% CI [−72.7, −44.3]). Mixed results were obtained for the Fall in 2022/2023 and for the Winter and holidays in both the studied years.

Conclusions

While the Fall holiday in 2021/2022 was associated with a decrease in RSV incidence in Sweden, our results do not support a universal effect of school holidays on reducing RSV transmission.

Works councils and workers’ party preferences in Germany
Authors: Jirjahn Uwe , Le Thi Xuan Thu
Published: June 2024

Research on the consequences of works councils has been dominated by economic aspects. Our study provides evidence that works councils have non‐financial consequences for society that go beyond the boundaries of the workplace. Using panel data from a large sample of workers in Germany, we show that works councils have an influence on workers’ party preferences. Works council presence is negatively associated with preferences for extreme right‐wing parties and positively associated with preferences for the Social Democratic Party and The Left. These results hold in panel data estimations including a large set of controls and accounting for unobserved individual‐specific factors. Our findings fit the notion that workplace democracy increases workers’ solidarity and their awareness of social and political issues. However, the influence of works council representation on party preferences is gender‐specific. Asymmetric gender norms within society may entail a lower responsiveness of women's party preferences to workplace democracy.
