Social, and Cultural Impact on Employees Job Satisfaction and Commitment to Organisations

Job satisfaction continues to be an essential aspect of exploring performance and its impact on productivity, organisational goals and societies at large has been widely studies. This study, aimed at investigating the impact of social, cultural, personal and environmental factors of job satisfaction and reviewing the relationship between job satisfaction and performance in organisation while exploring the interrelationships of the aforementioned antecedent’s groups. The study confirms the dual direction of connection that comprises a cycle of cause and effect relationship between, job satisfaction and performance and explores the mediating factors. The study encourages managers to reflect on their tacit method of managing employees, and exploring ways to apply explicit methods and provide work environment that is more conducive and unbiased. The study highlights the importance of considering job satisfaction and performance relationship holistically, through addressing the social, cultural, personal and environmental problems to improve employee performance.
Understanding the Role of Motives and Preferences of Social Networking Sites with Mental Health and Academic Performance Among Medical Students Al Ahsa, Saudi Arabia

Background: Globally, social networking sites are substantially used for indulgence, content, and interaction. Despite this, the worst impact of prolonged use of social networking sites has been associated with physical, mental, and long-term well-being. Its impact on medical students is a significant concern for many medical schools and administrators as users differ in purpose, preferences, and perceived usefulness. Objectives: This study aimed to examine the association of social networking sites’ preferences and motives with medical students’ mental well-being and academic performance. Methods: The cross-sectional study was conducted on 167 medical students of King Faisal University for three months, from October 2020 to December 2020. Participant’s information related to demographics, usage of social networking sites, mental well-being, and academic grades were collected through online questionnaires with valid measures. Results: Data analyses were performed using SPSS version 21. Almost all medical students were browsing social networking sites daily (98.2%). The most frequently visited sites were WhatsApp (97.6%), followed by YouTube (86.8%), and Instagram (77.8%). It was revealed that 3rd-year students were significantly using Facebook, mainly for fun. Besides, significantly better mental well-being was reported among females’ incentives to use social networking sites to keep in touch with family, friends, and relatives. It was also found that females were significantly more of being Instagram users and Snapchat users than males and observed significantly more having excellent academic grades than males. Conclusions: Our study suggests that students were motivated to connect with social networking sites for their various preferences or needs influenced by their beliefs, attitude, and plans.
Knowledge of acute stroke management and the predictors among Malaysian healthcare professionals

Background Despite rapid advances in acute ischaemic stroke (AIS) management, many healthcare professionals (HCPs) might not be aware of the latest recommended management of AIS patients. Therefore, we aimed to determine the level and factors associated with AIS management knowledge among Malaysian HCPs. Methods This cross-sectional online questionnaire study was conducted nationwide among 627 HCPs in Malaysia using the Acute Stroke Management Questionnaire (ASMaQ). Multiple logistic regression was used to predict the relationship between the independent variables (age, gender, years of service, profession, work setting, work sector, seeing stroke patients in daily practice, and working with specialists) and the outcome variable (good vs poor knowledge). Results Approximately 76% (95% CI [73–79%]) of HCPs had good overall knowledge of stroke. The highest proportion of HCPs with good knowledge was noted for General Stroke Knowledge (GSK) [88.5% (95% CI [86–91%])], followed by Advanced Stroke Management (ASM) [61.2% (95% CI [57–65%])] and Hyperacute Stroke Management (HSM) [58.1% (95% CI [54–62%])]. The odds of having poor knowledge of stroke were significantly higher among non-doctor HCPs [adjusted OR = 3.46 (95% CI [1.49–8.03]), P = 0.004]; among those not seeing stroke patients in daily practice [adjusted OR = 2.67 (95% CI [1.73–4.10]), P < 0.001]; and among those working without specialists [adjusted OR = 2.41 (95% CI [1.38–4.18]), P = 0.002]. Conclusions Stroke education should be prioritised for HCPs with limited experience and guidance. All HCPs need to be up-to-date on the latest AIS management and be able to make a prompt referral to an appropriate facility. Therefore, more stroke patients will benefit from advanced stroke care.
SERMs revisited: Can they improve menopausal care?

Selective estrogen receptor modulators (SERMs) are unique synthetic compounds that bind to the estrogen receptor and initiate either estrogenic agonistic or antagonistic activity, depending on the confirmational change they produce on binding to the receptor. Many SERMs have come to market, others have not. Unlike estrogens, which regardless of dose or route of administration all carry risks as a boxed warning on the label, referred to as class labeling, various SERMs exert various effects in some tissues (uterus, vagina) while they have apparent class properties in others (bone, breast). The first SERM, for all practical purposes, was tamoxifen (although clomiphene citrate is often considered a SERM). Tamoxifen was approved by the US Food and Drug Administration (FDA) in 1978 for the treatment of breast cancer and, subsequently, for breast cancer risk reduction. It became the most widely prescribed anticancer drug worldwide. Subsequently, when data showed that tamoxifen could produce a small number of endometrial cancers and a larger number of endometrial polyps, there was renewed interest in raloxifene. In preclinical animal studies, raloxifene behaved differently than tamoxifen in the uterus. After clinical trials with raloxifene showed uterine safety, the drug was FDA approved for prevention of osteoporosis in 1997, for treatment of osteoporosis in 1999, and for breast cancer risk reduction in 2009. Most clinicians are familiar with these 2 SERMs, which have been in clinical use for more than 4 and 2 decades, respectively.
Ecological Impact of End-of-Life-Tire (ELT)-Derived Rubbers: Acute and Chronic Effects at Organism and Population Levels

Considering the large amount of tires that reach the end of life every year, the aim of this study was the evaluation of both acute and chronic effects of end-of-life-tire (ELT)-derived rubber granules (ELT-dg) and powder (ELT-dp) on a freshwater trophic chain represented by the green alga Pseudokirchneriella subcapitata, the crustacean Daphnia magna and the teleost Danio rerio (zebrafish). Adverse effects were evaluated at the organism and population levels through the classical ecotoxicological tests. Acute tests on D. magna and D. rerio revealed a 50% effect concentration (EC50) > 100.0 mg/L for both ELT-dg and ELT-dp. Chronic exposures had a lowest observed effect concentration (LOEC) of 100.0 mg/L for both ELT-dg and ELT-dp on P. subcapitata grow rate and yield. LOEC decreased in the other model organisms, with a value of 9.8 mg/L for D. magna, referring to the number of living offspring, exposed to ELT-dg suspension. Similarly, in D. rerio, the main results highlighted a LOEC of 10.0 mg/L regarding the survival and juvenile weight parameters for ELT-dg and a LOEC of 10.0 mg/L concerning the survival and abnormal behavior in specimens exposed to ELT-dp. Tested materials exhibited a threshold of toxicity of 9.8 mg/L, probably a non-environmental concentration, although further investigations are needed to clarify the potential ecological impact of these emerging contaminants.
The Dynamic Behaviors of Photosynthesis during Non-Motile Cell Germination in Haematococcus pluvialis

Haematococcus pluvialis undergoes a three-phase process during the process of germination: first, repeated mitotic events; next, cytokinesis to form the zoospore; and finally, a fast release of motile cells. Physiological properties were measured using chlorophyll a fluorescence (OJIP) transient. The most obvious increase in K-value and L-value appeared at 17 h, suggesting that oxygen-evolving complex damage and lower energetic connectivity of the photosystem II units of the mother non-motile cell occurred. Compared to phase I, the values of the maximum quantum yield of PSII photochemistry (FV/FM) and PIABS increased significantly in phases II and III, suggesting that photosynthetic photochemical activity was greatly up-regulated during cytokinesis to form zoospores and the fast release of motile cells. Moreover, the significant increase in the K-band at 17 h and 22 h indicates that the PSII donor side was the limiting factor during the initial period of germination. All these results suggest that the cellular photosynthetic activity continues to strengthen during cytokinesis to form the zoospore and the fast release of motile cells, and it was postulated to meet the demands for sporangium swelling and new organelle formation.
Endocardial Regulation of Cardiac Development

The endocardium is a specialized form of endothelium that lines the inner side of the heart chambers and plays a crucial role in cardiac development. While comparatively less studied than other cardiac cell types, much progress has been made in understanding the regulation of and by the endocardium over the past two decades. In this review, we will summarize what is currently known regarding endocardial origin and development, the relationship between endocardium and other cardiac cell types, and the various lineages that endocardial cells derive from and contribute to. These processes are driven by key molecular mechanisms such as Notch and BMP signaling. These pathways in particular have been well studied, but other signaling pathways and mechanical cues also play important roles. Finally, we will touch on the contribution of stem cell modeling in combination with single cell sequencing and its potential translational impact for congenital heart defects such as bicuspid aortic valves and hypoplastic left heart syndrome. The detailed understanding of cellular and molecular processes in the endocardium will be vital to further develop representative stem cell-derived models for disease modeling and regenerative medicine in the future.
Untargeted Metabolomics Reveals the Effect of Selective Breeding on the Quality of Chicken Meat

The selection for improved body weight is an effective approach in animal breeding. Guangxi Partridge chickens have differentiated into two lines under selective breeding, which include line S and line D that have shown statistically significant differences in body weight. However, the meat quality analysis in our study indicated that the quality of breast and thigh muscles in line S chickens changed, which included increased values of L*, b*, and drip loss and decreased a* value, pH, and shear force in skeletal muscles. To illuminate the effect of selection on skeletal muscles, LC-MS/MS metabolomics was performed to explore differentiated metabolites in divergent tissues from the two chicken lines. The results of principal component analysis and orthogonal projection to latent structures discriminant analysis suggested that metabolites of different groups were separated, which suggested that selective breeding certainly affected metabolism of skeletal muscles. KEGG analysis identified that valine, leucine, and isoleucine biosynthesis, glycerophospholipid metabolism, and glutathione metabolism noteworthily changed in breast muscle. Amino sugars and nucleotide sugar metabolism, ascorbate and aldarate metabolism, the pentose phosphate pathway, pentose and glucuronate interconversions, fructose and mannose metabolism, and glycerophospholipid metabolism were remarkedly identified in thigh muscle. These screened pathways suggested oxidative stress in breast and thigh muscles, which corresponded with our previous results. Therefore, this study determined that glycerophospholipid metabolism conservatively functioned in muscle flavor and development but exhibited different anti-oxidative patterns in different skeletal muscles. Overall, the present study identified several differentiated metabolites and pathways for exploring differences in meat quality between different broiler populations.
Calibration and Cross-validation of Accelerometry in Children and Adolescents with Cystic Fibrosis

ABSTRACT Commonly used cut-points may misclassify physical activity (PA) in people with cystic fibrosis (CF). The aim of this study was to develop and cross-validate condition-specific cut-points in children and adolescents with CF. Thirty-five children and adolescents with CF (15 girls; 11.6 ± 2.8 years) and 28 controls (16 girls; 12.2 ± 2.7 years), had their energy expenditure and triaxial acceleration measured during six daily activities of varying intensities. Euclidean Norm Minus One (ENMO) and Mean Amplitude Deviation (MAD) were extracted using both GENEActiv (both wrists) and ActiGraph GT9X (both wrists and right waist) accelerometers. ROC curves were used to determine healthy and CF-specific raw acceleration cut-points for sedentary time (SED), moderate physical activity (MPA) and vigorous physical activity (VPA). The PA cut-points were generally lower in CF compared to controls for both ENMO (60.2–73.1 vs. 63.5–86.8 mg) and MAD (58.9–85.2 vs. 75.9–93.7 mg). These substantial inter-cut-point differences support the need for disease-specific cut-points.
Flexible working in the public sector – a case of inflexibility: senior managers' experiences

PurposeThe public sector is often considered the vanguard in terms of the availability and promotion of flexible working arrangements (FWAs). Despite this, little is known about how senior managers in the public sector engage with FWAs. This paper aims to address this gap, reporting on a number of issues, including the reality of FWAs, the existence of a flexibility stigma and whether this is gendered, and the drivers influencing the uptake of FWAs.Design/methodology/approachTheoretical insights of flexibility stigma from the literature and data from semi-structured interviews with senior managers in the Northern Ireland Civil Service explore the realities of FWAs at this level.FindingsThe findings indicate a decoupling between the rhetoric and reality of FWAs, with few senior managers availing of such arrangements. The authors also identify a complex web of issues that constrain senior managers' agency in shaping a positive culture of FWAs at senior management level in the Civil Service, including an inherent resistance to flexibility, a lack of visible role models and negative perceptions around progression. The findings also indicate deeply held perceptions among senior males and females that availing of FWAs is associated with a flexibility stigma. These perceptions were confirmed by the small number of senior females with caring responsibilities who were availing of FWAs.Research limitations/implicationsThe paper provides senior managers and human resource practitioners with insights into the difficulties associated with wide-scale FWA availability and use at senior levels of the Civil Service.Originality/valueThe findings of the study offer valuable insights into the experience of senior managers in the public sector as they engage with FWAs. The study, therefore, contributes to the limited literature in this area.
Coordinating Capacity Calculation via Electricity Market Coupling: Insights from the H2020 CROSSBOW Project

CROSS BOrder management of variable renewable energies and storage units enabling a transnational Wholesale market (CROSSBOW) is an EC-funded project, whose aim is to facilitate the shared use of energy resources by fostering cross-border management of variable renewable energies and storage units, enabling higher penetration of renewable energy sources (RES) whilst reducing network operational costs and improving economic benefits of clean energies and storage units. Towards these goals, CROSSBOW boosts regional cooperation among the system operators in Southeastern Europe (SEE), by deploying nine different tools to support the security coordination center (SCC) of the region. More specifically, the main CROSSBOW product, namely CROSSBOW Regional Operation Centre (CROSSBOW ROC) has proposed and demonstrated a set of functionalities for regional management and operation that enhance the existing regional structures, extending the capabilities of the already established Regional Security Coordinator (RSC) initiatives. Beyond enhancing RSC mandatory functions (including adequacy forecasts, coordinated security analysis, capacity calculations, and outage planning coordination), the ROC-BC product has developed new functions, linking the security considerations of involved TSOs with the operation of the fast-developing and harmonized electricity markets. In this paper, we investigate approaches for coordinated capacity calculation and cross-border trading via market coupling, developed within the ROC-BC product of CROSSBOW. Moreover, we present the final demonstration results as a part of ROC fundamental functionalities. Specifically, both net transfer capacity (NTC) and flow-based (FB) methods are examined and compared within a case study applying to the SEE region. The presented results demonstrate that the FB method exhibits better performance in all examined scenarios, considering three different key performance indicators (KPIs).
Inter-Sectoral Comparative And Competitive Advantages Of South Africa

The authors investigate the inter-sectoral comparative and competitive advantages of South Africa using Balassa technique. South Africa demonstrates significant, comparative and competitive-advantages in chemicals and the allied industries, metals and machinery/electrical sectors. There are comparative and competitive disadvantages in foot wear/head gear sector. This sector is followed by raw hides, skin, leather, and fur sectors. Most of the sectors fall in the middle ranks and there is an evidence of substantial manufacturing in South Africa. It is recommended that South Africa should work on attracting new investment, especially the foreign direct investment to improve those sectors which fall in the middle ranks. It is also recommended that South African channel resources from sectors which lack comparative and competitive advantages to sectors with such advantages, to ensure specialization where South Africaâ€™s productive capacities are efficient.
Generating Entrepreneurial Ideas for Business Development

Economic development and market changes have led to the need to generate entrepreneurial ideas in order to meet changing customer demands. However, these changes are not seen as opportunities for generating entrepreneurial ideas. Therefore, the purpose of this study is to identify and determine the most important elements in the process of forming entrepreneurial ideas. Mixed-method research that involved the modified Delphi technique, nominal group technique and interpretive structural modelling was used in this study. At first, a questionnaire was set up for the modified Delphi technique, followed by the nominal group technique and, finally, the interpretive structural modeling was used to determine the most important entrepreneurial ideas and model design. The experts involved in this study were 12 entrepreneurial lecturers from higher institutions. The findings show that evaluating and improving existing ideas is the most important element and should be given priority. Therefore, the findings of this study contribute a piece of valuable information for educators’ practice and for policymakers involved in shaping a more effective entrepreneurship education.
Design and Development of Two Novel Constructed Wetlands: The Duplex-Constructed Wetland and the Constructed Wetroof

Maribel Zapater Pereyra Abstract thesis: Design and development of two novel constructed wetlands: the Duplex-constructed wetland and the Constructed wetroof Constructed wetlands (CWs) are among the few natural treatment systems that can guarantee an efficient wastewater treatment and an appealing green space at the same time. However, they require large areas for their construction that in many cases is not available. In this thesis, two domestic wastewater treatment options were designed and studied with the purpose of having a low space requirement: the Duplex-CW and the constructed wetroof (CWR). The Duplex-CW is a hybrid CW composed of a vertical flow CW on top of a horizontal flow filter. The stacked arrangement is the key for reducing the CW footprint. The CWR is a shallow HF CW placed on the roof of a building, thus it does not occupy any land. Several modifications and improvements have been tested, in addition to the study of the treatment performance, in order to select the most appropriate Duplex-CW and CWR design. Overall, this thesis contributes to the development of two efficient domestic wastewater treatment technologies. The Duplex-CW area requirement is still higher than many CWs and therefore further improvements are necessary. The CWR is the foremost option to save land areas since it requires 0 m2 of land per person equivalent.
How the COVID-19 Pandemic Affects Risk Awareness in Dentists: A Scoping Review

Dentists are on the frontline of infection, especially when it comes to respiratory viruses like the new coronavirus. The purpose of this paper is to conduct a scoping review to better understand dentists’ risk awareness, awareness of COVID-19 symptoms, preventive measures, and effective methods of COVID-19 infection prevention and management. This paper systematically assesses the published literature on dentistry and COVID-19. Various electronic databases including Ovid MEDLINE, Scopus, Embase, and MEDLINE via PubMed were searched up to 9 September 2021. Overall, 39 papers were included. Almost the entirety of dentists (94.5%) reported awareness of the three most common COVID-19 symptoms, and a risk awareness score of about 90% was shown, while 88.2% of dentists reported adopting preventive measures. More than 50% did not want to treat infected people. While 70.3% of dentists recommended usage of N95 masks, the rate of dentists using them was below 40%. Sufficient awareness of risks during the pandemic was found in dentists. Although they were using preventive measures, there remains upside potential for adopting all recommended measures. Further, the usage of N95 masks is improvable, even though the benefit of wearing them could not be confirmed.
Role of Employee Networking Behavior in Predicting the Relationship between Perceived Supervisor Support and Career Satisfaction

This study aimed at exploring the role of employee networking behavior (NB) as an individual career self-management behavior of the relationship between perceived supervisor support (PSS) and career satisfaction (CS). An online survey was conducted based on the middle managers of commercial banks in Sri Lanka (N=86). Based on a regression analysis the study found that the PSS is positively associated with NB and CS whereas NB was positively associated with career satisfaction. The study also found that the NB mediates the relationship between PSS and CS. Current study suggests that the supervisor support promotes employees to network with others in the organization, which may experience greater success in facilitating employee career satisfaction. The outcomes of this research provide implications to the theories and models such as, social exchange theory, the extended model of the Social Cognitive Career Theory (SCCT) and the model of proactive behavior. The managerial implications, implications for future research and the limitations of the study are also discussed.
