ABSTRACTBackgroundSuicide is a major public health challenge, and a suicide attempt is an indicator of future mortality. This study provides a comprehensive analysis of initial suicide attempts.MethodsUsing Swedish national registers, we conducted a population-based cohort study of 3.7 million individuals followed from age 10 to a maximum age of 57. Suicide attempts were identified in hospital and death registers using ICD self-harm codes (intentional, with lethal methods, or leading to hospitalization or death). We investigated incidence, risk factors, outcomes, and familial aggregation, heritability, genetic correlations with psychiatric disorders, and healthcare visits in the month before and after initial suicide attempt.FindingsThe lifetime risk of suicide attempt in the study population was 4.6%, with greater risk in females and highest risk among ages 18-24. Overdose/poisoning were the most common methods. Prior history of psychiatric disorders, general medical diseases, and adverse life events were associated with increased risk of initial suicide attempt, while higher socioeconomic status was protective. Individuals with an initial suicide attempt were at substantially elevated risks of subsequent attempts (hazard ratio, HR, 23.4), suicide mortality (HR 16.4), and all-cause mortality (HR 7.3). One in ten families in Sweden had at least one individual who attempted suicide, and it tended to aggregate within families. The estimate of heritability was 42%, and genetic correlations of suicide attempts with psychiatric disorders ranged 0.48-0.85. At least 60% of those who made an initial suicide attempt had a healthcare contact in the month preceding the attempt.InterpretationThe study provides comprehensive insights into suicidal behavior. Suicide attempts are major markers of poor mental health and risk for subsequent morbidity and mortality; indeed, they may carry the greatest mortal risk seen in clinical psychiatry. Our results underscore the need for systematic prevention efforts for individuals who have recently attempted suicide.
Resistance but not endurance training suppresses glucocorticoid-induced leucine zipper (GILZ) expression in human skeletal muscle

Published: June 2024

ABSTRACTThe glucocorticoid-induced leucine zipper (GILZ) serves as an anti-inflammatory regulator of gene expression in different tissues and is also expressed in human skeletal muscle. GILZ mediates the anti-myogenic and myotoxic side effects of statins via a shift in the Akt/FoxO signaling pathways. Recent evidence suggests that GILZ suppression is regulated by physical exercise, with external load being the decisive factor. Interestingly, statin treatment is rarely tolerated by habitually exercising individuals due to statin-associated muscle symptoms (SAMS). The opposing regulation of GILZ underpins this detrimental interaction of key measures of cardiovascular prevention. This interaction hypothetically differs between diverging exercise modalities in a mechanosensitive manner. To verify emerging evidence, we conducted a systematic search of the Gene Expression Omnibus (GEO) repository for studies reporting the acute effects of either endurance (END), conventional resistance (RT), or eccentric resistance training (ECC). 15 studies with 204 participants (22 females; 182 males, 18 to 90 years of age) were included in the analysis. Participants’ activity levels ranged from sedentary to trained. RT resulted in the highest GILZ suppression, significantly differing from the expressional change after END (-0.46 ± 1.11 vs. -0.07 ± 1.08; p = 0.03), but not from ECC (-0.46 ± 1.11 vs. -0.46 ± 0.95; p = 0.19). Furthermore, subgrouping revealed that RT-experienced participants exhibited a more pronounced GILZ suppression than their inexperienced counterparts (-0.98 ± 0.66 vs. -0.34 ± 1.16; p = 0.001). Our results strengthen the assumption that mechanical loading can be considered a key mediator of exercise-induced changes in GILZ expression.

AbstractRepetitive transcranial magnetic stimulation (rTMS) holds promise as a non-invasive pain treatment. Given the link between individual peak alpha frequency (PAF) of resting-state electroencephalographic recordings and pain sensitivity, and the potential for rTMS to modulate PAF, we investigated these relationships through a secondary analysis of established rTMS-induced analgesia in an experimental model of sustained muscle pain.In a randomised, single-blind, sham-controlled experiment, 30 healthy adults underwent either active (n=15) or sham (n=15) high-frequency rTMS (20 min) to the left dorsolateral prefrontal cortex for five consecutive days following induction of sustained experimental pain by nerve growth factor (NGF) injected into the right extensor carpi radialis brevis muscle. The pain intensity was assessed daily for 14 days on a numerical rating scale (NRS). PAF of the resting state electroencephalography (5 min) was assessed before and one day after the five rTMS treatment days.The pre-registered analysis revealed no significant changes in PAF following five consecutive days of active (from 9.90±0.39 Hz to 9.95±0.38 Hz) or sham (from 9.86±0.44 Hz to 9.81±0.35 Hz) rTMS, suggesting that the impact of rTMS on NGF- induced pain is independent of PAF modulation. However, exploratory analysis indicated an association between the absolute difference of baseline PAF to 10 Hz (i.e. the rTMS frequency) and higher NRS pain ratings at Day 5 in participants receiving active rTMS. This suggests that rTMS is more efficient when delivered close to the individual PAF and necessitates further exploration of PAF’s role in rTMS-induced pain relief.Disclosures:The Center for Neuroplasticity and Pain (CNAP) is supported by the Danish National Research Foundation (DNRF121).

At ambient conditions SrAl4 adopts the BaAl4 structure type with space group I4/mmm. It undergoes a charge-density-wave (CDW) transition at TCDW=243 K, followed by a structural transition at TS=87 K. Temperature-dependent single-crystal x-ray diffraction (SXRD) leads to the observation of incommensurate superlattice reflections at q=σc* with σ=0.1116 at 200 K. The CDW has orthorhombic symmetry with the noncentrosymmetric superspace group F222(00σ)00s, where F222 is a subgroup of Fmmm as well as of I4/mmm. Atomic displacements mainly represent a transverse wave, with displacements that are 90 deg out of phase between the two diagonal directions of the I-centered unit cell, resulting in a helical wave. Small longitudinal displacements are provided by the second harmonic modulation. The orthorhombic phase realized in SrAl4 is similar to that found in EuAl4, except that no second harmonic could be determined for the latter compound. Electronic structure calculations and phonon calculations by density functional theory (DFT) have failed to reveal the mechanism of CDW formation. No clear Fermi surface nesting, electron-phonon coupling, or involvement of Dirac points could be established. However, DFT reveals that Al atoms dominate the density of states near the Fermi level, thus corroborating the SXRD measurements. SrAl4 remains incommensurately modulated at the structural transition, where the symmetry lowers from orthorhombic to b-unique monoclinic. The present work draws a comparison on the modulated structures of nonmagnetic SrAl4 and magnetic EuAl4 elucidating their similarities and differences, and firmly establishing that although substitution of Eu to Sr plays little to no role in the structure, the transition temperatures are affected by the atomic sizes. We have identified a simple criterion that correlates the presence of a phase transition with the interatomic distances. Only those compounds XAl4−xGax (X=Ba, Eu, Sr, Ca; 0<x<4) undergo phase transitions, for which the ratio c/a falls within the narrow range 2.51<c/a<2.54.

Authors: Jarzębowski Sebastian , Mondy Christopher , Dalewska-Mądra Izabela , Enz Matias 
Published: June 2024

PurposeLike a well-designed procurement strategy, a well-designed rolling stock strategy promotes the development of a railroad company and contributes to its competitive advantage. Effective implementation of the rolling stock strategy enhances the likelihood of enjoying the benefits of the strategy’s design. A successful implementation relies on the strategy being known, understood, controlled and communicated to the entire organization.Design/methodology/approachThe research consists of an extensive literature review as well as a series of workshops with rolling stock suppliers, railway authorities and representatives and rail users.FindingsThis paper presents a collection of solutions for passenger rail rolling stock procurement. The authors offer guidance to the strategic procurement of rolling stock in the European Union (EU) and propose key performance indicators to measure the effectiveness of a rolling stock strategy.Research limitations/implicationsWhile this study presents a thorough evaluation of rolling stock procurement practices, it is limited by its geographic isolation. Future studies should compare the procurement practices discussed here to others in the EU, as well as in North America, South America and Asia. Additionally, this study focused on the passenger rail segment. Passenger transport is an important function of the rail network in the EU, but future research should expand the assessment of rolling stock procurement strategies to freight rail as well.Originality/valueOverall, this work provides visibility into common rolling stock procurement practices in complex EU railway markets. This work expands the literature through a review of these practices and through enabling research into best practices or a commonly accepted procurement model.

Authors: de Bekker Ankie , Reckman Päivi , Kemper Peter , Lemmens Lidwien 
Published: June 2024

PurposeInvesting in prevention could be of great benefit to public health. Especially for people with health risks, such as overweight, depressive symptoms, low social-economic status or people who experience loneliness or a sedentary lifestyle. In the Netherlands, different parties are responsible for financing and organising selective and indicated preventive interventions: the government, municipalities and health insurance companies. The aim of this study was two-fold: First, to describe the transition towards a sustainable prevention infrastructure. And second, to gain insight into barriers and facilitators associated with intersectoral collaboration regarding organising prevention for high-risk groups.Design/methodology/approachA longitudinal qualitative study was conducted among collaborative networks working together to build a prevention infrastructure. During a five-year study period, 86 semi-structured interviews were held. The COM-B model was used for data analysis.FindingsBarriers to intersectoral collaboration are: unknown (cost-)effectiveness, limited incentives to invest in collaboration, lack of clarity about responsibilities, differences in priorities and organisational culture between municipalities and health insurers. Facilitators are commitment, trust, sharing knowledge between parties, meeting regularly within the network and acknowledgement of mutual responsibilities. Also, national policy interventions targeted at the development of regional prevention infrastructures facilitated collaboration.Originality/valueThis study shows that collaboration regarding prevention is becoming increasingly common. It can be concluded that the transition towards a sustainable prevention infrastructure has started. The relationship between key stakeholders, like municipalities and health insurers, is generally stronger than it was five years ago. They have a better understanding of each other’s interests and expectations.

Published: June 2024

PurposeThis study investigates the effect of economic policy uncertainty on the firm profitability through moderating role of logistics infrastructure index using US non-financial firms listed at NASDAQ.Design/methodology/approachWe used secondary data set which includes firm-level indicators of 2,323 non-financial US firms listed at NASDAQ over the period of 1998–2018. Ordinary least squares regression with multiple fixed effects used to analyze the data and estimate hypotheses.FindingsThe results show that economic policy uncertainty negatively impacts the firm’s profitability whereas the logistics infrastructure positively moderates the negative impact of EPU on the firm’s profitability.Research limitations/implicationsEconomic policy uncertainty is a significant challenge for managerial decision making and a direct threat to a firm’s profitability. The results of this study imply that the state of logistics infrastructure must be considered as an important policy tool by the senior management to mitigate the negative impact of economic policy uncertainty and to safeguard a firm’s profitability.Originality/valueThis study highlights that logistic infrastructure plays an important role in alleviating the adverse effect of economic policy uncertainty on the profitability of a US non-financial firm.
Learning to do good: developing capabilities to deliver social value from public procurement within English public authorities
Authors: Lonsdale Chris , le Mesurier Nicholas 
Published: June 2024

PurposeThis paper aims to explore how social procurement (SP)-related capabilities might be developed within public authorities.Design/methodology/approachThe paper utilizes qualitative research, based upon an inductive research design. This leads to a model to inform future research and practice.FindingsWithin the context of a “disconnected and nascent institutional field of practice” (Loosemore et al., 2023), the research generated rich data illustrating how certain English public authorities have developed relatively mature SP capabilities and applied them within the procurement process. The former included the appointment of “champions”; the founding of groups/units; training using webinars, online resources and case studies; “toolkits”, including policy documents, process guidance and measurement tools and networking. The latter included consultation with social value recipients and close engagement with both internal stakeholders and suppliers. The research also revealed the internal political skills of “champions”, as SP challenges incumbent logics regarding procurement objectives and practices.Practical implicationsFirst, the paper provides a potential roadmap for organisational capability development. Second, the research makes clear that public authorities should not seek to reinvent the capability wheel. Engagement with peers, advisory bodies, established “toolkits”, etc. is imperative, with much expertise publicly available. Third, it also suggests that smaller public authorities might seek to act as part of a consortium rather than go it alone, given the investment required for effective SP. Fourth, the research showed that practitioners need to understand SP as not simply a development challenge but also a political one.Originality/valueThe paper contributes to the literature by analysing SP from the largely overlooked resource-based perspective, by providing rich data on buy-side practice, by usefully adding to the literature's emerging “practice theme” and by offering guidance to buy-side managers within public authorities.
Linking the UN sustainable development goals to life cycle impact applied to a university campus
Authors: Giusti Gabriela , Farrapo Junior Antonio Carlos , Silva Daiane Vitória , Silva Diogo A.L. 
Published: June 2024

Purpose
The study aims to explore the relationship between the SDGs and the environmental and social impacts of university classes. It evaluates the potential contributions of different teaching models to the SDGs, providing insights into sustainable teaching systems.

Findings
In-person classes exhibited hotspots in transportation and energy consumption. Scenarios I and II, involving virtual and hybrid classes, increased eutrophication potential and water scarcity due to higher food consumption, negatively impacting SDGs. However, all scenarios showed positive contributions to SDGs 2, 3, 6, 9, 11, 12, 13, 14 and 15.

Design/methodology/approach
This research integrates Life Cycle Assessment (LCA) with the United Nations Sustainable Development Goals (SDGs) to assess the environmental and social impacts of classes at the Federal University of São Carlos, Sorocaba campus in Brazil. Three scenarios were analyzed: (I) virtual classes, (II) hybrid classes and (III) in-person classes with improved energy efficiency.

Research limitations/implications
The study primarily focuses on environmental and social impacts, excluding other factors like class quality. Integrating Life Cycle Costing and Life Cycle Sustainability Assessment could provide a more holistic evaluation in the future.

Practical implications
The methodology adopted offers valuable insights for managing the impacts of university performance and aligning teaching systems with the SDGs. It enables institutions to make informed decisions for sustainability in education.

Social implications
The research emphasizes the importance of considering social impacts alongside environmental ones when assessing sustainability in educational institutions. It encourages universities to engage stakeholders in sustainability efforts.

Originality/value
This research innovatively combines LCA and the SDGs in the context of university education providing a replicable methodology for evaluating and enhancing sustainability in teaching systems and from a more quantitative perspective.
Rebranding after international acquisitions: challenges of legitimation in emerging and developed countries
Authors: Ramos Manoella Antonieta , Andersson Svante , Aagerup Ulf 
Published: June 2024

PurposeThis study describes how a multinational enterprise (MNE) gains acceptance after rebranding acquired brands from different countries among its internal and external stakeholders and identifies factors that influence this process.Design/methodology/approachThe study employed a single case-study approach, including 18 semi-structured in-depth interviews with employees of a firm involved in the rebranding process in six countries. The countries are Sweden, Germany, the United States, Brazil, Colombia and Mexico.FindingsThe findings reveal how the MNE integrated brands it acquired in different international markets into one overarching corporate brand. The study shows that in emerging countries, external legitimation (external implementation process, country profiles and customer buy-in) constitutes the most significant challenge. By contrast, in developed countries, internal legitimation (employee buy-in and internal implementation process) is more challenging.Research limitations/implicationsThe study contributes to and extends the rebranding literature by using a legitimation lens to analyze the rebranding process. This lens shows how internal and external stakeholders are both crucial to successful rebranding. The study provides a comprehensive perspective of the process, identifies challenging factors and differentiates between their importance in emerging and developed countries.Originality/valueTo address the dearth of research on how firms legitimize a new brand in different national contexts, the study compares the rebranding process in multiple countries and discusses the factors influencing the rebranding process.
How to mitigate the negative effect of PDB on DIY preference
Authors: Li Yuan , Ruefenacht Matthias , Maas Peter 
Published: June 2024

Purpose
This paper aims to explore the negative effect of power distance belief (PDB) on do-it-yourself (DIY) preference. It extends previous studies by delving into the underlying mechanism and identifying three theoretically driven moderators that could mitigate this negative effect.

Design/methodology/approach
The paper uses secondary data at the country level and conducts three experiments involving participants from the USA and Germany.

Findings
The results suggest that the adverse impact of PDB on DIY preference exists through the underlying mechanism of attitude toward customer power. This negative effect can be mitigated when individuals with high PDB focus on status, find themselves in a position of low power or engage in activities within a private consumption setting.

Practical implications
For DIY companies, this study offers crucial insights into the impact of cultural values on consumers’ DIY preferences. By customizing their marketing communications, companies can resonate with high PDB customers more effectively.

Originality/value
This research enhances DIY literature by introducing novel moderators within a theoretical framework, explaining why DIY preference might be low among individuals with high PDB and suggests ways to attenuate this effect.
