(Un)deserving of work-life balance? A cross country investigation of people’s attitudes towards work-life balance arrangements for parents and childfree employees

ABSTRACT Work-life balance (WLB) represents a fundamental part of people’s well-being and is a key policy priority at national and organizational levels in many industrialized countries. Yet a significant gap exists in our understanding of employees’ ability to use WLB arrangements, particularly employees without children. We address this gap by exploring the perceived deservingness of childfree employees to use WLB arrangements in Italy and the Netherlands. Using a 2 × 2 experimental design, we study the perceived deservingness of childfree people to use organisational work-life balance arrangements compared to parents, with a particular focus on gender and country differences. We further investigate the attribution of priority to make use of work-life balance arrangements across these same groups. While we find no significant differences in perceptions of deservingness, the results do show significant differences in who is considered to need priority in using WLB arrangements in the workplace. Respondents attribute greater priority to female employees with children than female employees without children. The attribution of priority for male employees does not differ between parents and childfree employees. This interaction effect was only found in the Italian sample. We discuss the implications of our results for our understanding of work-life balance policy supports.
Skeletal Muscles of Patients Infected with SARS-CoV-2 Develop Severe Myofiber Damage upon One Week of Admission on the Intensive Care Unit

Many critically ill patients infected with SARS-CoV-2 have been submitted to an intensive care unit (ICU). Patients with a SARS-CoV-2 infection that survive critical illness are confronted with months of physical impairments. To maximize recovery, it is important to understand the musculoskeletal involvement in critically ill patients infected with SARS-CoV-2. The aim of the present study was to assess the myocellular changes in SARS-CoV-2 patients that occur throughout the first week of ICU admission. In n = 22 critically ill patients infected with SARS-CoV-2, a biopsy sample from the vastus lateralis muscle was obtained at day 1–3 and day 5–8 following ICU admission. Fluorescence microscopy was used to assess type I and type II muscle fiber size and distribution, myonuclear content, and muscle tissue capillarization. Transmission electron microscopy was used to support quantitative data at an ultrastructural level. Changes in type I and type II muscle fiber size showed large inter-individual variation. The average change in type I fiber size was +309 ± 1834 µm2, ranging from −2129 µm2 (−31%) to +3375 µm2 (+73%). The average change in type II fiber size was −224 ± 1256 µm2, ranging from −1410 µm2 (−36%) to +2592 µm2 (+48%). Ultrastructural observations showed myofibrillar and hydropic degeneration, and fiber necrosis. This study shows that ICU patients admitted with SARS-CoV-2 suffer from substantial muscle fiber damage during ICU admission. These results are a call for action towards more specialized rehabilitation programs for patients admitted to the ICU with SARS-CoV-2 infection.
Application of TETRAD in information systems theory development using knowledge sharing literature: case-study based approach

The discovery of causal relationships from empirical data is an important problem in theory development. We investigate the use of TETRAD IV to help researcher in a theory development phase. We applied TETRAD IV, a heuristic search software that used for discovering causal effect relationship between variables based on a specific model. To performed our task, we defined two case studies. First, we re-analyse an existing model or theory using original correlation matrix data from a paper in Knowledge Sharing field. Second, we validated the existing model by conducting a survey using data from 90 respondents (Bachelor, master, PhD candidate) in the University of Twente academic setting, which pointed out Blackboard as the primary online learning tools to support teaching as well as sharing the knowledge. The results give us suprising remarks. From the first case study, TETRAD IV discovered spurious relationship in the model, which are there is no causal effect between its variables. Furthermore, using our own data, we found the same results of causal linkage as we have in the first case study. These results give the idea of what truly occurs given the real data. Thus, it is critical to explore the relationships among the variables in the model using exploratory research tools, as TETRAD IV, to aid and guide the researcher in theory development phase.
Exploration and prioritization of lean techniques in a hotel supply chain

Purpose The purpose of this paper is to develop a framework for identification, categorization and prioritization of lean techniques adopted in a hotel supply chain. Design/methodology/approach A survey tool is used for the identification of lean techniques that are relevant to a hotel supply chain. The targeted sample includes experts from 50 four- and five-star hotels in the United Arab Emirates (UAE) that confirmed experience in implementing lean practices across hotels supply chain. A Supplier-Inputs-Process-Outputs-Customers (SIPOC) chart and experts’ opinion are used to allocate and categorize the identified lean techniques across the construct of the hotel supply chain. Finally, analytical hierarchy process (AHP) is used to prioritize the criteria and sub-criteria of adopted lean techniques. Findings Study results have identified six main categories of lean practices and 19 specific lean techniques as relevant to a hotel supply chain. The identified categories include JIT, Kaizen, Quality, Inventory, Maintenance and Standardization. The study found that JIT and Kaizen take the top priority among the identified categories of lean practices. In line with that, on-time service to customers, effective improvement system and on-time delivery from suppliers were found to be the three most relevant lean techniques to a hotel supply chain. Research limitations/implications The study has targeted a representative sample of hotels with experience in implementing lean practices. Study findings have several implications to researchers and practitioners for effective adoption of lean techniques within a hotel supply chain. However, the accuracy and credibility of results obtained from this research including SIPOC allocation and lean categorization are highly dependent on the accuracy and credibility of collected empirical data from surveyed hotels within the study context. Results of AHP prioritization also depend on the credibility of judgements made by the hotels’ supply chain experts. Practical implications The study provides the hospitality industry with a structured approach that can help in a prioritized adoption of most relevant lean techniques across the hotel supply chain to reduce wastes, create value, increase efficiency and improve the service level. Study findings can be used by hotel management to direct and focus the effort of lean capacity building, resources allocation and implementation plans. Originality/value Limited research is available on lean management in the context of a hotel supply chain. Also, most of the previous research is focused on lean impacts, while academics and practitioners agree that the identification and prioritization of most relevant lean techniques is crucial to the successful implementation of lean management for waste reduction and value creation. This research addresses this important issue in hotel supply chains and proposes a structured approach for effective lean adoption.
Environmentally Associated Variation in Dispersal Distance Affects Inbreeding Risk in a Stream Salamander

Avoiding inbreeding is considered a key driver of dispersal evolution, and dispersal distances should be especially important in mediating inbreeding risk because the likelihood of mating with relatives decreases with dispersal distance. However, a lack of direct data on dispersal distances has limited empirical tests of this prediction, particularly in the context of the multiple selective forces that can influence dispersal. Using the headwater stream salamander Gyrinophilus porphyriticus, we tested whether spatial variation in environmental conditions leads to differences in dispersal distances, resulting in spatial variation in the effect of dispersal on inbreeding risk. Using capture-recapture and population genomic data from five streams, we found that dispersal distances were greater in downstream reaches than upstream reaches. Inbreeding risk trended lower for dispersers than nondispersers in downstream reaches but not in upstream reaches. Furthermore, stream reaches did not differ in spatial patterns of individual relatedness, indicating that variation in inbreeding risk was in fact due to differences in dispersal distances. These results demonstrate that environmentally associated variation in dispersal distances can cause the inbreeding consequences of dispersal to vary at fine spatial scales. They also show that selective pressures other than inbreeding avoidance maintain phenotypic variation in dispersal, underscoring the importance of addressing alternative hypotheses in dispersal research.
Harnessing the x86 Intermediate Rings for Intra-Process Isolation

Modern applications often involve the processing of sensitive information. However, the lack of privilege separation within the user space leaves sensitive application secrets such as cryptographic keys just as unprotected as a ”hello world” string. Cutting-edge hardware-supported security features are being introduced. However, the features are often vendor-specific or lack compatibility with older generations of the processors. The situation leaves developers with no portable solution to incorporate protection for the sensitive application component. We propose LOTRx86, a fundamental and portable approach for user-space privilege separation. Our approach creates a more privileged user execution layer called PrivUser by harnessing the underused intermediate privilege levels on the x86 architecture. The PrivUser memory space, a set of pages within process address space that are inaccessible to user mode, is a safe place for application secrets and routines that access them. We implement the LOTRx86 ABI that exports the privcall interface to users to invoke secret handling routines in PrivUser. This way, sensitive application operations that involve the secrets are performed in a strictly controlled manner. The memory access control in our architecture is privilege-based, accessing the protected application secret only requires a change in the privilege, eliminating the need for costly remote procedure calls or change in address space. We evaluated our platform by developing a proof-of-concept LOTRx86-enabled web server that employs our architecture to securely access its private key during an SSL connection. We conducted a set of experiments, including a performance measurement on the PoC on both Intel and AMD PCs, and confirmed that LOTRx86 incurs only a limited performance overhead.
Distributed Handoff Problem in Heterogeneous Networks With End-to-End Network Slicing: Decentralized Markov Decision Process-Based Modeling and Solution

Heterogeneous networks (HetNets) with end-to-end (E2E) network slicing are regarded as effective approaches to meet diverse service requirements from vertical industries. Due to the dense deployment of base stations (BSs) and the complicated associations between BSs and E2E network slices (NSs) in the scenario, the handoff problem faces challenges of the huge system state space and handoff action space and the considerable communication overhead. In this paper, we take these issues into account and consider a distributed E2E NS handoff decision framework in the HetNet. A decentralized Markov decision process (DEC-MDP)-based model is formulated for the distributed E2E NS handoff problem, and the jointly observable and random characteristics of the DEC-MDP are analyzed. To obtain a theoretical performance reference, the original distributed E2E NS handoff problem is simplified, and a Nash equilibrium-based performance bound is given. More practically, the multi-agent double deep Q-network-based distributed handoff (MA-DDQN-DH) algorithm with the centralized training and decentralized executing framework is proposed. Simulation results show that the Nash equilibrium-based performance bound is reasonable, and the proposed MA-DDQN-DH algorithm performs well in the comparison.
Underwater sound speed profile parameters estimation in asynchronous network

The technology of underwater wireless acoustic sensor networks (UWSNs) plays an important role in many commercial and military applications in underwater. In UWSNs, there exist many challenges posed by the specific characteristics of underwater acoustic channel, such as sound propagation speed is a function of depth with unknown parameters. Besides, time synchronization of anchor nodes is a crucial part of the applicable network. Time synchronization of anchor nodes as well as estimation of sound speed parameters considering an isogradient profile is explored here. While the previous efforts do not take into account these factors, this article assumes only one synchronized anchor node in the network and enables joint synchronization of the other anchor nodes and the estimation of the propagation delays between the anchor nodes using a weighted linear least square solution. Then, it uses the estimated propagation delays to estimate the unknown parameters of the sound speed profile using a conventional Gauss‐Newton algorithm with approximately three iterations to converge. Validation of the proposed method is done by the numerical simulations and to demonstrate the effectiveness of the proposed method we compare the results with Cramer‐Rao bound average.
Hepatic Transcriptome Analysis Provides New Insight into the Lipid-Reducing Effect of Dietary Taurine in High–Fat Fed Groupers (Epinephelus coioides)

A transcriptome analysis was conducted to provide the first detailed overview of dietary taurine intervention on liver lipid accumulation caused by high–fat in groupers. After an eight-week feeding, the fish fed 15% fat diet (High–fat diet) had higher liver lipid contents vs. fish fed 10% fat diet (Control diet). 15% fat diet with 1% taurine (Taurine diet) improved weight gain and feed utilization, and decreased hepatosomatic index and liver lipid contents vs. the High–fat diet. In the comparison of the Control vs. High–fat groups, a total of 160 differentially expressed genes (DEGs) were identified, of which up- and down-regulated genes were 72 and 88, respectively. There were 49 identified DEGs with 26 and 23 of up- and down-regulated in the comparison to High–fat vs. Taurine. Several key genes, such as cysteine dioxygenase (CDO1), ADP–ribosylation factor 1/2 (ARF1_2), sodium/potassium–transporting ATPase subunit alpha (ATP1A), carnitine/acylcarnitine translocase (CACT), and calcium/calmodulin–dependent protein kinase II (CAMK) were obtained by enrichment for the above DEGs. These genes were enriched in taurine and hypotaurine metabolism, bile secretion, insulin secretion, phospholipase D signaling pathway, and thermogenesis pathways, respectively. The present study will also provide a new insight into the nutritional physiological function of taurine in farmed fish.
Diagnosis and Clinical Management of Chagas Disease: An Increasing Challenge in Non-Endemic Areas

Abstract Chagas disease (CD) is caused by the parasite Trypanosoma cruzi, and it is endemic in Central, South America, Mexico and the South of the United States. It is an important cause of early mortality and morbidity, and it is associated with poverty and stigma. A third of the cases evolve into chronic cardiomyopathy and gastrointestinal disease. The infection is transmitted vertically and by blood/organ donation and can reactivate with immunosuppression. Case identification requires awareness and screening programmes targeting the population at risk (women in reproductive age, donors, immunocompromised patients). Treatment with benznidazole or nifurtimox is most effective in the acute phase and prevents progression to chronic phase when given to children. Treating women antenatally reduces but does not eliminate vertical transmission. Treatment is poorly tolerated, contraindicated during pregnancy, and has little effect modifying the disease in the chronic phase. Screening is easily performed with serology. Migration has brought the disease outside of the endemic countries, where the transmission continues vertically and via blood and tissue/organ donations. There are more than 32 million migrants from Latin America living in non-endemic countries. However, the infection is massively underdiagnosed in this setting due to the lack of awareness by patients, health authorities and professionals. Blood and tissue donation screening policies have significantly reduced transmission in endemic countries but are not universally established in the non-endemic setting. Antenatal screening is not commonly done. Other challenges include difficulties accessing and retaining patients in the healthcare system and lack of specific funding for the interventions. Any strategy must be accompanied by education and awareness campaigns directed to patients, professionals and policy makers. The involvement of patients and their communities is central and key for success and must be sought early and actively. This review proposes strategies to address challenges faced by non-endemic countries.

The planar Gunn diode offers the potential of microwave, milli‐metric and THz‐based oscillators, which can be fabricated as part of a microwave monolithic integrated circuit (mmic). The paper develops an electrical representation of an aluminum gallium arsenide (AlGaAs) based planar Gunn diode with an active channel length of approximately 4 μm and width of 120 μm, embedded in an oscillator circuit. The work indicates a maximum simulated RF output power of +5 dBm compared with published experimental results of −19 dBm for similar diodes.
Predicting death risk analysis in fully vaccinated people using novel extreme regression-voting classifier

Vaccination for the COVID-19 pandemic has raised serious concerns among the public and various rumours are spread regarding the resulting illness, adverse reactions, and death. Such rumours can damage the campaign against the COVID-19 and should be dealt with accordingly. One prospective solution is to use machine learning-based models to predict the death risk for vaccinated people by utilizing the available data. This study focuses on the prognosis of three significant events including ‘not survived’, ‘recovered’, and ‘not recovered’ based on the adverse events followed by the second dose of the COVID-19 vaccine. Extensive experiments are performed to analyse the efficacy of the proposed Extreme Regression- Voting Classifier model in comparison with machine learning models with Term Frequency-Inverse Document Frequency, Bag of Words, and Global Vectors, and deep learning models like Convolutional Neural Network, Long Short Term Memory, and Bidirectional Long Short Term Memory. Experiments are carried out on the original, as well as, a balanced dataset using Synthetic Minority Oversampling Approach. Results reveal that the proposed voting classifier in combination with TF-IDF outperforms with a 0.85 accuracy score on the SMOTE-balanced dataset. In line with this, the validation of the proposed voting classifier on binary classification shows state-of-the-art results with a 0.98 accuracy.
The trend and characteristics of China studies published in SSCI public administration journals: A bibliometric analysis

Scholars of China studies have been keen to publish in SSCI journals since mainland Chinese universities started to embrace international academic standards in the early 1990s. The widespread assumption is that publishing in SSCI journals contributes to not only the promising career of an individual scholar but also knowledge accumulation and development in the Chinese public administration field. However, it remains unanswered concerning which topic of China studies is more likely to arouse interest from journal editors and reviewers. As SSCI publications become increasingly desirable yet challenging for Chinese scholars, this study attempts to offer recommendations by exploring the trend and characteristics of China studies published in SSCI public administration journals, which are included in the Web of Science (WoS) database. This study uses bibliometric analysis to conduct a systematic review on 584 articles of China studies published in 47 SSCI public administration journals. It aims to generate various quantitative results, including journal ranking, title and keywords co-occurrences network, citation analysis, co-citation network, co-authorship network, bibliographic coupling network, and so on. In this way, this paper will reveal the latest trend and characteristics of China studies published in SSCI public administration journals. Consequently, it will help scholars enhance the quality and quantity of China studies, advance their chances of success in SSCI public administration journals, and broaden and deepen their contribution to the global academic community.
Cocreation from Emerging Opportunities: Occupational Therapists' Perspectives on Supporting Older Persons, in Japan

Introduction Practices of occupational therapists, particularly those supporting older persons with physical impairments, remain overly focused on remediating impairments, and implementation of occupation-centered practices remains fraught with difficulties. In Japan, this issue exists across the continuum from acute care to rehabilitation settings and into the community. This is despite the existence of international models and frameworks that place occupation at the core of the profession. Accordingly, there is a need to better understand how occupational therapists respond to the call for occupation-centered practices across the said continuum of care with this population. The aim of this study was at exploring and understanding occupational therapists' experiences of supporting the resumption of occupations among older persons with physical impairments, in Japan. Methods Embedded in a constructivist world view, this was a qualitative focus group study. Four focus groups (two in urban areas and one each in rural and semirural areas), consisting of seven or eight occupational therapists with at least three years of relevant practice experience, convened twice to narrate and explore their support of older persons. All were participating voluntarily with confidentiality of their participation being guaranteed by the researchers. They met for a third time to verify emerging analytic results. Data were analysed using a reflective thematic analysis. Results Identified were three themes, namely, calling forth powers of occupations, imagining client's future, and cocreating plots, which we synthesized into recurring cocreations from emerging opportunities. Discussion. Supporting the resumption of occupations among older persons with physical impairments hinges on repeated processes of identifying possibilities for occupation, followed by actions to bring these (e.g., images of clients' future) into reality. Occupations' healing properties (i.e., occupations' powers) can be used to assist clients in experiencing health and well-being. The results suggest a reframing of occupational therapy practices as recurring processes of recognizing opportunities for occupation, followed by actions whereby these possibilities are turned into reality. Occupational therapy effectiveness might be enhanced when goals and methods are repeatedly and creatively aligned with the evolving plots cocreated between the client, therapist, and stakeholders.
