Strategic Workforce Management in Malaysia's Food and Beverage Industry: Overcoming Challenges and Cultivating Sustainable Innovation

The food and beverage (F&B) industry is a critical driver of Malaysia’s economic and social development. While contributing significantly to GDP and employment, the sector faces persistent challenges, including high employee turnover, resource constraints, and limited workforce retention strategies. This paper explores the dynamics of perceived organizational support (POS), workforce sustainability, and predevelopment practices within Malaysian small and medium enterprises (SMEs). Drawing on robust theoretical frameworks and empirical data, the findings illuminate the roles of organizational justice, supervisor support, and employee engagement policies. The study offers practical recommendations to foster workforce stability, innovation, and sustainable growth, positioning this research as a strategic blueprint for advancing human resource practices in the F&B industry.

Why the irremediability requirement is not sufficient to deny psychiatric euthanasia for patients with treatment-resistant depression

Treatment-resistant depression (TRD) holds centrality in many debates regarding psychiatric euthanasia. Among the strongest reasons cited by opponents of psychiatric euthanasia is the uncertainty behind the irremediability of psychiatric illnesses....

Comparing surgical techniques and results of secondary ischemic mitral regurgitation: a state-of-the-art literature review.

Surgery for mitral valve disease is a developing area with a wide range of surgical options. There is growing evidence on the best approach for secondary ischemic mitral regurgitation (SIMR) when the pathology is within the ventricle. The goal of this literature review is to provide a comprehensive comparison of surgical treatments for SIMR. The initial screening process included PubMed, Medline and Embase to identify randomized controlled trials, propensity-matched observational series, meta-analyses and unmatched observational series. The terms used were 'mitral valve disease', 'secondary mitral regurgitation', 'secondary ischemic mitral regurgitation', 'functional mitral regurgitation', 'restrictive mitral annuloplasty', 'subvalvular repair', 'Trans Catheter Edge to Edge Repair and echocardiography coupled with secondary mitral regurgitation', 'secondary ischemic mitral regurgitation', and 'functional mitral regurgitation'. Six strategies have been identified for treating SIMR. These include mitral valve replacement (MVR), restrictive mitral annuloplasty, surgical revascularisation (with and without mitral annuloplasty), subvalvular procedures [papillary muscle (PM) approximation, PM relocation, ring and string procedure], procedures directly targeting the mitral valve (edge-to-edge repair and anterior leaflet enlargement), and transcatheter heart valve therapy. There is a deficiency of robust empirical data to enable meaningful comparisons between MVR, mitral valve repair (including subvalvular repair), and transcatheter mitral valve procedure. This review will definitively analyze the current outcomes of transcatheter mitral valve procedure using the edge-to-edge mitral valve repair technique and standard surgical mitral valve procedures in patients with secondary mitral regurgitation (MR). In addition, the seminar highlights the role of left ventricular assist devices in managing SIMR. It discusses the advantages and limitations of each intervention. Currently, there is no consensus on the optimal management strategy for patients with SIMR. Therefore, a multidisciplinary cardiac team should manage patients with secondary MR to ensure the best outcome by matching the ideal intervention with the patient.

Evaluation of Health Associations With Height-Normalised Abdominal Body Composition Indices: A Single-Centre Cross-Sectional Study.

Traditional metrics such as body mass index (BMI) and waist circumference (WC) fail to accurately assess the health outcomes associated with abdominal adiposity, because they neglect the intricacies of adipose tissue distribution. Notably, the variability in body composition scaled to height remains underexplored in Chinese demographics. This study introduces height-normalised indices of abdominal adiposity using computed tomography (CT) scans and further assesses their associations with various health outcomes. In a large, diverse Chinese population (n = 1054 healthy individuals; n = 1159 with dyslipidemia; n = 803 with diabetes; n = 1289 with cardio-cerebrovascular diseases; n = 1108 with cancers; and n = 509 with abnormal bone mas), abdominal CT scans were performed and allometric growth model analyses were used to derive height-normalised indices (body composition/heightβ). Logistic regression models assessed the associations between these indices and health outcomes. Distinct scaling powers were observed for visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT) and total abdominal adipose tissue (TAT), as well as for sagittal diameter (SAD), with marked sex differences. Powers for VAT were 1.786 ± 1.270 for males and 1.274 ± 0.692 for females. Powers for SAT were 2.266 ± 0.856 for males and 1.656 ± 0.497 for females. Powers for TAT were 2.141 ± 0.967 for males and 1.438 ± 0.489 for females. Powers for SAD were 0.646 ± 0.217 for males and 0.678 ± 0.141 for females. After controlling for age, BMI and WC, VAT/heightβ, TAT/heightβ and SAD/heightβ retained their significantly positive associations with the odds of health outcomes, whereas SAT/heightβ did not. Our findings endorse the clinical utility of height-normalised indices, particularly VAT/heightβ, TAT/heightβ and SAD/heightβ, in health outcomes assessment. These indices, grounded in robust empirical data, underscore the necessity of a nuanced approach in obesity-related health evaluations, advocating for a departure from conventional methods like BMI.

Raised in conditions of psychosocial deprivation: Effects of infant institutionalization on early development

BackgroundInstitutionalization is associated with a substantial developmental risk. Ethical constraints make it challenging to obtain robust empirical data on the effects of deprivation. Furthermore, because institutionalized children often face global deprivation, assessing the specific effects of psychosocial deprivation becomes difficult. Moreover, limited research exists on factors explaining interindividual differences. ObjectiveTo investigate developmental outcomes of children raised in institutions in conditions of psychosocial deprivation and to identify possible risk and protective factors at institutional and child levels. Participants and SettingSecondary analyses of data collected 1958–1961 in Switzerland in a population-based survey of institutionalized infants and toddlers. Participants (n = 332, Mage = 11.1 months, SD = 6.4, 48.2 % female, 45.3 % Swiss) were matched with a comparison group of 332 children raised in families (Mage = 10.9 months, SD = 6.2, 50.0 % female, 100 % Swiss). MethodsDevelopmental status was assessed using the standardized Brunet-Lézine Developmental Test. Additional data were obtained from administrative records and through observations. ResultsInstitutionalized children had significantly lower developmental quotients than the comparison group (d = −1.60, p < 0.001), with most prominent differences for language and social skills (d = −1.21/−1.20, p < 0.001). Within the institutionalized group, higher interaction time, higher birth weight, more regular family contact, and a shorter duration of institutionalization were associated with better developmental outcomes. ConclusionsThis study emphasizes the impact of isolated psychosocial deprivation on early development and identifies several risk and protective factors. To reduce developmental risk of institutionalization, the results are globally relevant for infants placed in institutions with comparable conditions today.

Distribuição espaço-temporal da biomassa e carbono florestal acima do solo em Floresta Tropical Seca sob pressão antrópica, Brasil

The present study aimed to characterize the spatiotemporal variability of aboveground biomass and carbon in two fragments of Dry Tropical Forest in the Brazilian semi-arid region using the kriging interpolation technique. One fragment experienced vegetation suppression for alternative land use, while the other had no history of use or wood extraction. The vertices of 80 plots (20 m x 20 m) were georeferenced, and biomass and carbon were estimated using allometric equations adjusted for Caatinga species. Spatial analyses and mapping of aboveground biomass and carbon were performed using GS+ software, with semivariograms fitted using spherical, exponential, and Gaussian models. The research aims to fill gaps regarding the impacts of inadequate forest exploitation in Dry Tropical Forests, specifically on the spatiotemporal distribution of biomass and carbon, as anthropogenic pressure can cause significant environmental degradation, resulting in reduced stocks. This investigation seeks to elucidate these dynamics and provide insights for management and conservation strategies based on robust empirical data, in addition to answering the following questions: Does the history of anthropogenic interventions in Dry Tropical Forest areas cause variations in the spatial distribution of biomass and carbon stocks that can be detected by the kriging method? Which attributes related to conservation and anthropogenic use reflect the spatial distribution of biomass and carbon stocks in Dry Tropical Forest areas? The results showed a strong spatial dependence of biomass and carbon stocks in both studied areas, indicating the influence of the areas’ use history. The conserved fragment presented a more homogeneous spatial distribution, suggesting that the selective and unauthorized wood extraction was dispersed throughout the area.

Assessment of rock mass properties and load-bearing potential in low-grade metamorphic rocks: A study from the Tigray region, Ethiopia

&lt;p&gt;This study presents an engineering geological investigation aimed at assessing the bearing capacity of the proposed site for the Meli gold processing plant (GPP) located in the northwestern region of Tigray, Ethiopia. The geological composition of the site predominantly comprises low-grade metamorphic rocks, with intermediate metavolcanic rocks being the most prevalent. This research utilized an innovative combination of empirical methodologies, including the Hoek–Brown and Mohr–Coulomb criteria, to evaluate the strength and elasticity characteristics of the rock mass. Additionally, the rock mass foundation for the GPP was rigorously classified using renowned systems such as the rock mass rating (RMR), quality index (Q), and geological strength index (GSI). Employing five different empirical equations to estimate bearing capacity, this study significantly advances our understanding by comparing these diverse methodologies, which is a novel approach in this geological context where engineering property data are scarce or non-existent. The bearing capacities determined using the Hoek–Brown and Mohr–Coulomb criteria ranged from 11.6 to 46.2 MPa and 7.9 to 10.5 MPa, respectively. These findings not only offer valuable insights into the assessment of bearing capacity in metamorphic rock formations but also underscore the effectiveness of combining multiple empirical approaches to enhance the reliability of geological assessments. This research contributes to the advancement of construction practices and enhances project planning strategies in comparable geological environments, particularly highlighting the utility of robust empirical data in the absence of extensive drilling data. By integrating comprehensive empirical analyses, the study provides a methodological framework that significantly aids in informed decision-making for future projects located in similar geological settings.&lt;/p&gt;

Turning a spotlight on construction logistics for a sustainable urban environment—a review of current policy concepts and literature

Construction logistics is an influential participant in the overall urban freight network and a bottle neck for an efficient construction process. Especially in the urban area professionalization of its management may reduce negative impacts on the environment from which stakeholders, like construction companies, policymakers and residents, do profit. In order to shed light on construction logistics in the urban environment in particular, a two-step methodological approach was pursued, which reconciles scientific findings with consideration in policies for the first time. Therefore, the current state of research was investigated by performing a systematic literature review and applying bibliometric keyword co-occurrence analyses in the first place. Moreover, policy papers (grey literature) on urban freight transportation of the 20 biggest cities in the DACH-region (Germany, Austria, Switzerland) were analyzed for their consideration of construction logistics in an initial case study. The results demonstrate limited consideration with only four cities paying deliberate attention within their overall logistics policy concepts and just one city providing construction logistics-specific policy recommendations. This is in line with the findings that although construction logistics in the urban environment is an emerging topic in academia, it is currently underrepresented in the context of urban logistics research. Therefore, combined results suggest insufficient translation of research findings into actionable policies despite existing literature providing possible ways to design future policies, e.g., by supporting decision-making. In conclusion, strategic management of construction logistics in the urban environment should be paid more attention to from both policy and academia in proportion to its environmental and socio-economic effects as well as its impact on the whole construction process. In that regard, predominately robust empirical data is needed in order to legitimate effective and sustainable concepts for urban construction logistics for both public and private actors.

The impacts of COVID-19 on K-8 science teaching and teachers

Some science education researchers have presented either isolated findings on specific points in time during the pandemic or non-empirical insights or suggestions for how teachers, district leaders, policymakers, and others should take up the learnings from the pandemic to move science education forward. However, there are few studies published to date that provide robust and longitudinal empirical data on what science instruction looked like throughout the pandemic and the magnitude of the impacts of the pandemic on science instruction when compared to pre-pandemic science teaching and learning. We conducted a primarily survey-based study on science instruction and enactment of the Next Generation Science Standards (NGSS) in K-8 classrooms throughout the COVID-19 pandemic. This analysis also incorporates a longitudinal dataset from grade 6–8 teachers across California on their NGSS instruction prior to and throughout the first year of the pandemic, providing insight on instruction over multiple years before and throughout distance learning. Our findings highlight the challenges that teachers and students faced during the pandemic, as well as the significant impacts that distance learning appeared to have on science instruction and teachers’ ability to provide NGSS-aligned instruction. However, we also found that a year after the initial school closures, teachers’ science instruction began to show improvements both in the frequency of science instruction (how often they were able to provide science instruction through distance learning) and the quality of science instruction (how often teachers were able to provide instruction that was aligned with the goals of the NGSS). Implications of this work are far reaching and may impact teachers, students, administrators, policymakers, professional learning providers, and curriculum developers regardless of whether science instruction occurs through distance learning or in-person moving forward.

Challenges to Understanding the Role of Cognition in the Assessment of Activities of Daily Living in Patients with Spinal Cord Injury: A Narrative Literature Review

<h3>Research Objectives</h3> When working in acute rehabilitation settings with physically compromised populations, including patients with spinal cord injury (SCI), assessing one's ability to manage basic and instrumental activities of daily living (ADLs) is a crucial component of treatment and discharge planning. Neurocognitive diagnoses, in particular, are predicated on the extent to which one's cognitive deficits negatively impact ADLs. However, parsing apart the relative contribution of cognitive versus physical changes on ADLs can be particularly challenging in patients with SCI as decline in ADLs may be attributable to motor limitations, cognitive decline, or both. This narrative review sought to investigate the existing literature regarding cognitive assessment and the role of cognition in functional assessment in SCI <h3>Design</h3> Narrative literature review. <h3>Setting</h3> N/A. <h3>Participants</h3> N/A. <h3>Interventions</h3> N/A. <h3>Main Outcome Measures</h3> N/A. <h3>Results</h3> Robust empirical data suggest substantial cognitive impairment in individuals with SCI. However, there is a lack of standardized cognitive assessments designed for use specifically with this population. Further, few studies have been published assessing the role of cognition in functional assessment of patients post-SCI, and those reviewed suggest that current functional measures with cognitive components have limited ecological validity. This can ultimately result in a lack of convergence among one's cognitive status, motor limitations, and ability to function independently post-discharge. <h3>Conclusions</h3> While many of the existing measures of functional assessment in SCI speak to the general capacity of physical recovery and level of physical functioning post-injury, few address ability to resume daily activities following discharge from a cognitive perspective. This lack of inclusion of cognition in functional assessment presents challenges for rehabilitation psychologists and neuropsychologists in making accurate diagnoses and treatment plans while working with patients with new onset cognitive difficulties, particularly within the context of physical disability such as SCI. <h3>Author(s) Disclosures</h3> None.

Technology clinical trials: Turning innovation into patient benefit.

Health care needs to continuously evolve and innovate to maintain the health of populations. Technology has the potential to enable better patient engagement and ownership, as well as optimise therapeutic interventions and data-science approaches to facilitate improved health care decisions. Yet, to date, technological innovation has not resulted in the rate of change that could have been predicted from other sectors. This article discusses multiple reasons for this and proposes a newly tested and deployed solution: the technology clinical trial. The technology clinical trial methodology has been developed through working directly with patients, clinical and medical devicetrial experts. This approach enables researchers to use the complex environment of health care as an opportunity to transform the pace of innovation and create new care pathways. Instead of testing a single innovation, researchers can ‘step back’ and systematically review all areas of the patient's journey for potential optimization. Then integrate novel data science, technological advances, process updates, behavioural science, and patient engagement to co-create a streamlined multidisciplinary solution. As a result, this research has the potential for larger advances due to the emergent benefits that can arise when the individual elements work together as a whole. These potential benefits are then robustly tested, characterised and measured in the trial environment to ensure that future application of the innovative pathway is supported by the robust empirical data health care requires.

Towards Designing a Validated Framework for Improved Clinical Legal Education: Empirical Research on Student and Alumni Feedback

The pedagogical advantages of employing a Clinical Legal Education (“CLE”) teaching and learning strategy have been acclaimed in literature for almost a century and it continues to be ideally suited to cater to modern education expectations. As an agent for social change, CLE offers law students an effective gateway to participate in, and be influenced by, fundamental social justice problems while it also improves access to justice for the indigent. Though the clinical literature is replete on expected benefits for clinical law students, very little (if any) verifiable empirical research, independently sourced and evaluated, has been published to assess the veracity of these claims in support of CLE. After receiving a funding grant from the University of Stellenbosch Fund for Innovation and Research into Learning and Teaching, the University of Stellenbosch Law Clinic appointed an independent, external agency to conduct empirical research through an extensive measure and evaluation exercise. The aim of the project was to source, document and analyse robust empirical research data about the Faculty of Law’s CLE module, Practical Legal Training 471. The project involved the sourcing and collation of formal student evaluation feedback reports spanning a period of nine years. Additional alumni and current student data were gathered either by online questionnaire or by telephonic interview. The research was aimed at eliciting quantitative as well as qualitative responses.&#x0D; The purpose of this article is to describe the applicable methodology and aims of the research project, to unpack and discuss the resulting empirical data, and to draw certain conclusions based on the findings of this research about CLE’s impact on law students’ experience specifically relating to their practice-readiness and social justice sensitivities. It is suggested that this research will prove both interesting and useful to law teachers involved in relevant programmes at other higher education institutions. The data and evidence detailed herein will assist them to conduct their research and to make substantiated recommendations for the development of CLE programs on a broader national and international level. This research will also add to the body of knowledge on students and student learning and allow for recommendations regarding the creation of a broader implementation framework for improved CLE.

A Tentative Theory of Change to Evaluate Jurisdictional Approaches to Reduced Deforestation

Sub-national jurisdictions are promoted as strategic levels of governance for achieving reduced deforestation objectives. Jurisdictional approaches (JA) emerged as government-led, holistic approaches to forest and land use management across one or more legally defined territories. Despite increasing popularity amongst the science and practitioner communities, there is a lack of robust empirical data documenting their effectiveness in delivering environmental, social and economic outcomes. In this paper, we contend that further clarification of the JA concept would help its evaluation. More specifically, we suggest that current evaluation practices of JA would be strengthened if they were based on a theory of change clarifying the causal linkages between the interventions associated with a given JA and their effects. By integrating select empirical knowledge on JA with a selection of middle-range theories from the literature on collective environmental governance, we design a generic theory of change for JA, which is articulated around two intermediary outcomes, namely the emergence of collaboration and social learning. We also formulate hypotheses regarding the conditions that enable or hinder these collective intermediary outcomes of JAs. We acknowledge that another fundamental challenge for JAs is to remove or block the external contradicting signals that still fundamentally drive deforestation. Thus, JA interventions need to operate not only at the jurisdictional level, but also beyond.

What Have We Here? The Relationship between Law Student Attendance and Wellbeing

Two significant areas of contemporary legal education research are student wellbeing and student attendance. It is well established that, when compared with the general population, university students, including those studying law, are at greater risk of experiencing psychological distress and, when they do, it is likely to be at higher levels. Student attendance at face-to-face classes is also gaining traction as a research area, but there is a dearth of robust empirical data in this area. Moreover, the relationship between attendance and wellbeing is underexplored. This article seeks to address this gap in the literature.We recently undertook a large empirical, mixed method study at our university, involving a survey of law students, a manual count of student attendance, and student focus groups. While the primary purpose of the study was to better understand motivations for student attendance or non-attendance, using a constructivist methodology, we extracted a wealth of qualitative data that gave additional insights into both student wellbeing and the attendance–wellbeing nexus. In this article, we present these findings through the lens of Self-Determination Theory and its principles of relatedness, autonomy and competence and in particular explore the tension between autonomy and relatedness when students do not attend lectures.

Rates and Correlates of Mental Health Symptoms in Currently Competing Elite Athletes from the Australian National High-Performance Sports System

Elite athletes are at risk of mental ill-health via exposure to sports-related stressors and the overlap in competitive playing years with the peak age of onset of mental ill-health. Despite this risk, there is a paucity of robust empirical data on mental health symptoms in currently competing athletes. The purpose of this study was to assess the prevalence and correlates of mental health symptoms in a representative, national sample of elite athletes and to compare rates against published community norms. A cross-sectional, anonymous, online survey was administered to all categorised (e.g. highest level) athletes, aged 17years and older, registered with the Australian Institute of Sport (n = 1566). Main outcomes were self-reported scores on validated measures of psychological distress, probable 'caseness' (i.e. the experience of mental health symptoms that would usually warrant a need for care by a health professional), risky alcohol consumption, body weight and shape dissatisfaction, self-esteem, life satisfaction and problem gambling. Correlates of outcomes included demographic, individual vulnerability (e.g. social support, coping style) and sport-related variables. The participation rate was 51.7% (n = 810), of whom 749 athletes completed most or all outcomes measures. Compared to published community norms, athletes were significantly more likely to report 'high to very high' psychological distress (9.5% vs 17.7%, respectively) and to meet the threshold for 'probable caseness' (19% vs 35%). In contrast, athletes reported significantly lower rates of risky alcohol consumption, problem gambling and body dissatisfaction compared to community norms, and conversely higher self-esteem and life satisfaction. The adjusted odds of psychological distress and caseness were increased in athletes who reported prior treatment for a mental health problem (OR = 1.28-2.84), inadequate social support (OR = - 2.59 to 0.37) and more recent adverse life events (OR = 0.61-1.32); while, the odds of risky alcohol consumption were lower in female athletes (OR = - 1.36) and para-athletes (OR = - 1.20). In a representative and national sample of currently competing elite athletes, inclusive of gender and para-status, psychological distress and probable caseness were elevated relative to community norms, although other aspects of functioning were as good as, if not better than, community peers. Sports medicine and mental health professionals working with elite athletes should screen for psychological distress in athletes who may otherwise appear to be well-functioning, to provide timely, optimal treatment.

Function-Based and Multi-Scale Approach to Green Roof Guidelines for Urban Sustainability Transitions: The Case of Bogota

A growing number of local green roof niches across the globe are transitioning into the mainstream domain. Guidelines are key to this process, as they define technological environments and set the criteria for best practices in a given socio-technical setting. Although the German Forschungsgesellschaft Landschaftsentwicklung Landschaftsbau (FLL) cornerstone guidelines provided solid empirical ground and established technical parameters for the successful application of green roofs across continents, investigations about alternative green roof guidelines for emerging markets remain very scarce. The paper presents the inclusive approach followed by the Bogota Green Roof Guidelines, which were the result of a multi-actor participatory process that examined how to embrace a wide range of emerging green roof technologies and local adaptations while promoting quality of application at different scales, regardless of the system used, and despite the absence of local robust empirical data on performance parameters. As a result, Bogota’s Green Roof Guidelines incorporated ad hoc elements: (1) new definitions and taxonomy, (2) function-based contents, (3) multi-scale approach, and (4) performance scoping. These aspects are discussed to provide novel insights for the advancement of green infrastructure policies in diverse institutional settings aiming to promote quality and simultaneously support markets that make room for a wide variety of green infrastructure practices.

LeopardPanthera pardusdensity in southern Mozambique: evidence from spatially explicit capture–recapture in Xonghile Game Reserve

AbstractRigorous status estimates of populations of large carnivores are necessary to inform their management and help evaluate the effectiveness of conservation interventions. The African leopardPanthera pardusfaces rising anthropogenic pressures across most of its contracting sub-Saharan range, but the scarcity of reliable population estimates means that management decisions often have to rely on expert opinion rather than being based on sound evidence. This is particularly true for Mozambique, where little is known about the ecology or conservation status of leopard populations as a result of prolonged armed conflict. We used camera trapping and spatially explicit capture–recapture models to provide a leopard density estimate in Xonghile Game Reserve in southern Mozambique, which is part of the Greater Limpopo Transfrontier conservation initiative. The estimated population density was 2.60 ± SE 0.96 leopards/100 km2. Our study provides a baseline leopard density for the region and the first empirical density estimate for southern Mozambique. Our results also suggest that current methods used to set trophy hunting quotas for leopards, both in Mozambique and elsewhere in Africa, may be leading to unsustainable quotas, which highlights the importance of robust empirical data in guiding conservation policy.

Open government data and the private sector: An empirical view on business models and value creation

The release of government data in an open format is broadly expected to generate innovation and economic value. However, despite the emerging public notoriety of this issue, literature is still scarce regarding the commercial application of open government data. The main goal of this study is to understand how firms use open government data to create value. More specifically, we aim to identify what types of use are currently in place and which industries are more prominent in exploiting open government data. Building on the analysis of a dataset of 178 firms that use open government data across various industries in the U.S. we find twelve different atomic models. Additionally, our findings suggest that the way in which open government is used to create value is contingent to the firms' activities. Supported by robust empirical data, we anticipate that our research produces practical insights to entrepreneurs as well as firm managers in deriving value from public datasets, and equip government officials with relevant evidence for advocacy and policy-making.
