Green Human Resource Management Practices and Environment Sustainability: From Empirical Evidence
Authors: Kalei Anne
Published: June 2024

Green human resource management, if well designed and implemented, is undeniably one of the avenues that is envisaged to contribute towards the actualization of the Sustainable Development Goals (SDGs). This paper set out to interrogate the extant literature on Green Human Resource Management (GHRM) Practices and their nexus to environmental sustainability. One of the emerging issues within business communities is the campaign of going green (GG). GHRM is a drive which helps to create a green workforce that can understand and appreciate green culture in businesses and institutions. It is paramount to note that human resource and their systems are the basic foundation of any business. It is a fact that the human resource function in an organization is responsible for planning and executing those eco-friendly policies to create a green environment. The study was mainly a desktop, where a review and synthesis of the existing empirical literature was undertaken. The main sources of the data and information for purposes of this paper were largely relevant reports, journals and books. Past writings indicate that there is a growing need for the integration of environmental management into Human Resource Management (HRM) research practice. This article pursues an integrated view of the literature on Green HRM. It examines and interrogates the current empirical literature in the area of green human resource management with a view to pointing out and synthesizing the gray areas and suggesting a way forward towards enriching knowledge and practice in the area of green human resource management. Finally, the paper suggests some key HR initiatives towards creating and nurturing GHRM practices and behaviour for environmental sustainability. This article draws together the extant literature in this area in suggesting managerial implications and research direction in GHRM. Hence, the papers demystifies the debate and discussion on GHRM and suggests new fronts that requires research focus.

Published: June 2024

The purpose of this study is to unearth the contribution of ethical orientation and marketing strategies in catalyzing the usage of locally made products using empirical evidence from Sub-Saharan Africa. This study adopted a cross-sectional and quantitative approach. A self-administered questionnaire was used to collect data from a sample of 165 manufacturing firms in Uganda, and Smart PLS software supported data analysis. Study results indicate that the ethical orientation and marketing strategies of local firms positively and significantly contribute to the usage of locally made products. Marketing strategies provide a conduit through which the ethical orientation of firms affects consumer usage of locally manufactured products. While several studies have been conducted on product usage, this study provides initial empirical evidence on the mediating effect of marketing strategies in the association between ethical orientation and the usage of locally manufactured products from Sub-Saharan Africa.

Published: June 2024

The use and search for antimicrobial drugs derived from plants have accelerated in recent years. The present study was aimed to determine the antimicrobial, antibiofilm and membrane stabilization activities of plant extracts. Crude extracts of four plants namely, Mikania scandens (L.), Mimosa pudica (L.), Murraya paniculata (L.), and Syzygium aromaticum (L.) were tested against eleven human pathogens including four biofilm producing bacterial strains Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae and Staphylococcus aureus, and one fungal strain Candida albicans. The antimicrobial activities as well as minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of the extracts were evaluated using disc diffusion and macro-broth dilution methods respectively. Among the plant extracts, ethanol extract of S. aromaticum exhibited the largest zone of inhibition 35 mm in diameter against Bacillus subtilis at 500 µg/disc concentrations. The lowest MIC (1000 µg/ml) and MBC (2500 µg/ml) were determined against P. aeruginosa with the same extract of S. aromaticum. In case of time kill assay, S. aromaticum extract showed the lowest optical density (OD600) 0.2 against E coli in 3h at MBC concentration. Moreover, the same extract of S. aromaticum displayed the strong antibiofilm activity, inhibiting 100% biofilm formation of E. coli at 2×MIC concentration. Furthermore, in vitro experiment was performed to evaluate membrane stabilization activity of plant extracts and S. aromaticum showed 100% activity in stabilizing cell membranes, preventing hemolysis of red blood cells. Therefore, this study provides valuable insight for designing antimicrobial products to efficiently eliminating human infections, and the plant extracts could be the potential antimicrobial agent.

COMPARISON OF ESTIMATED GLOMERULAR FILTRATION RATE USING DIFFERENT FORMULAS IN TURKISH POPULATION
Authors: Cattik Busra Nur , Umar Rashida Muhammad
Published: June 2024

Objective: Creatinine-based equations are generally used in clinical practice to estimate glomerular filtration rates (GFR), but values are not usually consistent. This study aimed to evaluate the difference between estimated GFR values using different equations.
Material and Method: Adult Turkish patients with serum creatinine measurements between January to December 2021 and complete demographic data were included. GFR values were calculated using 5 different formulas. GFR calculated with Cockcroft-Gault were normalized to body surface area and added to the comparison. Difference between GFR values and KDIGO stages were evaluated. Albunin/creatinine ratio (ACR) of patients was also assessed.
Result and Discussion: A total of 305 patients with average age of 52.92 years were included. Six different GFR calculations were recorded with median values between 51.70 to 71.77 ml/min/1.73m2. Formula of The Modification of Diet in Renal Disease with the race factor for Turkish population resulted in the lowest eGFR values. The ACR values of only 42 patients were available and it was negatively correlated to all GFR values and positively correlated to all KDIGO stages (p<0.05). There were noteworthy variations in GFR values, based on patient demographics and/or equations. The need for novel practical methods for estimating GFR in general and specific patient populations are necessary.
Assessing the population consequences of disturbance and climate change for the Pacific walrus
Authors: Johnson DL , Eisaguirre JM , Taylor RL , Garlich-Miller JL
Published: June 2024

Climate change and anthropogenic disturbance are increasingly affecting wildlife at a global scale. Predicting how varying types and degrees of disturbance may interact to influence population dynamics is a key management challenge. Population consequences of disturbance (PCoD) models provide a framework to link effects of anthropogenic disturbance on an individual’s behavior and physiology to population-level changes. In the present study, we develop a Pacific walrus (Odobenus rosmarus divergens) PCoD model to encompass the population-level effects of both anthropogenic disturbance and climate change. As the Arctic becomes increasingly ice-free, walruses spend more time at coastal (vs. ice-based) haulouts, from which they must expend more energy to reach foraging areas and where they have an elevated risk of mortality. Concurrently, sea ice loss is increasing the anthropogenic footprint in the Arctic (e.g. fisheries, shipping, energy exploration), which creates additional disturbance. We applied the PCoD model to 4 scenarios (ranging from optimistic to pessimistic) which incorporate different global sea ice model projections along with varying degrees of anthropogenic disturbance. All scenarios indicated a decline in Pacific walrus vital rates by the end of the 21st century, but our results demonstrated that the intensity of that decline could be mitigated by global efforts to reduce carbon emissions, along with local management and conservation efforts to protect important coastal haulouts and foraging grounds. In summary, we introduce a flexible PCoD modeling framework in a novel context which will prove useful to researchers studying species threatened by rapid environmental change.

The research project "Projecting Knowledge: The Magic Lantern as a Tool for Mediated Science Communication in the Netherlands, 1880-1940" aimed write the history of the lantern lecture in the Netherlands. Its sub-project "Science for People" focused on the public format of the lantern lecture, organized outside academic environments, for a variety of adult audiences, and with the goal of transmitting some sort of knowledge. This was the premise for this dissertation, which meant to be a first survey into this historical phenomenon guided by the main question: How was public knowledge transmission and science communication mediated through the optical lantern in illustrated lectures organized in the Netherlands between 1880 and 1940 in the Netherlands, what subjects were treated, which audiences were addressed and what different types of speakers are to be distinguished?
This research was largely based on primary sources such as newspapers, periodicals and other archival material, including correspondence, personal notebooks, or associations’ newsletters. My goal was to understand how and why—as well as what, who, and where—historical stakeholders engaged in this cultural practice, and exactly how common was the organization of public lantern lectures to disseminate knowledge. And while this is still a largely unknown cultural practice in historical scholarship, this research has shown that, particularly in the first decades of the twentieth century, public lantern lectures were not only a usual occasion in Dutch social life, but a truly pervasive practice that reached a variety of audiences and was used to discuss a variety of topics from the paintings of Rembrandt to strategies to fight tuberculosis or how to care for your chickens. In fact, during the winter season, in the first decades of the twentieth century, public lantern lectures were almost a daily occurrence, organized by a myriad of associations.
Carbon nanofiber growth from methane decomposition over Ni-based catalysts: a balancing act
Authors:   , Schoemaker Suzan Eva
Published: June 2024

Hydrogen plays an important role in the energy transition. However, it is important to produce this hydrogen in a green way. Unfortunately, the current production routes involve the emission of CO2. The catalytic decomposition of methane is a good alternative: during this reaction methane is split into hydrogen gas and solid carbon. The solid carbon can have different forms like, e.g. graphene, carbon black or carbon nanofibers. Carbon nanofibers (CNFs) are special because of their interesting properties (lightweight materials, good conductivity and very strong). The reaction takes place in three stages: 1) decomposition of methane, 2) diffusion of carbon atoms through the catalyst particle 3) the formation of carbon layers. The reaction is sensitive to changes and moves quickly out of balance. As a result, the catalyst might deactivate quickly.

In this research, we systematically studied several factors that influence the reaction. We used Ni-based catalysts, as these are the most active for this reaction. To circumvent rapid deactivation, bimetallic NiCu catalysts were used. A graphitic support material was used to restrict support effects. We have used a thermogravimetric analyzer as reactor, operated at differential conversion. The TGA allows us to follow the carbon growth in-situ. In our studies, we were mainly interested in the initial growth rate, the final carbon yield and the catalytic lifetime. In addition, in-situ gas cell transmission electron microscopy was used, which allowed us to directly visualize CNF growth from ensembles of individual metal catalyst nanoparticles. Increasing the temperature resulted in a faster reaction, but also in a shorter catalyst lifetime. Additionally, different fiber structures formed at different temperatures. Next to an optimal temperature, we observed an optimal catalyst particle size and composition. Normally, highly active catalysts are preferred in catalysis. However, in this case, highly active catalysts also deactivated quickly, limiting the final yield, hence slow and steady wins the race.

6 Ekim 1973 tarihinde Mısır ve Suriye askeri kuvvetlerinin İsrail’e karşı sürpriz bir şekilde saldırıya geçmesiyle birlikte başlayan ve 27 Ekim 1973 tarihinde sağlanan ateşkes neticesinde sona eren Yom Kippur savaşının ardından, 26-28 Kasım 1973 tarihinde Arap Petrol İhraç Eden Ülkeler Örgütü (OAPEC) üyeleri Cezayir’de bir toplantı düzenlemişlerdir. Düzenlenen bu toplantıda söz konusu örgütün üyeleri, İsrail’i destekleyen tüm ülkelere petrol ambargosu uygulanmasını kararlaştırmışlar ve bu kararı toplantının hemen ardından İsrail yanlısı olan ülkelere bildirilmişlerdir. Bu kararın İsrail destekçisi ülkelere bildirilmesini takiben petrole bağımlı olan gelişmiş ülkeler bir anda büyük bir ekonomik krizin içerisine sürüklenmişlerdir. Gelişmiş ülkelerin karşı karşıya kaldığı bu kriz, ilerleyen süreçte küresel düzeyde hissedilen geniş kapsamlı bir iktisadi bunalımın meydana gelmesine yol açmıştır. Ortaya çıkan küresel ekonomik bunalımının kendisine yönelik olumsuz etkilerini en aza indirmek isteyen Türkiye, bu süreçte Arap ülkeleriyle daha yakın ilişkiler içerisinde olmaya yönelik bir dış politik izlemiştir. Bu çalışma, 1973 Petrol Krizi sırasında Türkiye’nin izlediği dış politikayı, uluslararası ilişkiler literatürü içerisinde özel bir öneme sahip olan ulusal çıkar kavramı çerçevesinde incelemeyi amaçlamaktadır.
Exploring the Impact of Digital Media on Teenagers' Mental Health: A Comprehensive Review of Positive Effects, Negative Consequences, and the Role of Digital Detox
Authors: Liu Junye
Published: June 2024

This review examines the effect of social media usage on teenagers' mental health, both positive and negative while exploring how digital detox may help teenagers improve their mental well-being.In positive effect. According to Seabrook et al (2016), Orben (2020), teenagers found that social media usage boosted their sociality and provided more academic resources.On the negative effect, considering that social media usage is now a daily routine, the excessive use of social media is believed to link with anxiety, depression and sleeping disorders (Twenge et al. 2018; Levenson et al. 2016).Cyberbullying has also been one of the main issues affecting teenagers daily as it worsens the mental health problems. According to a survey conducted by Columbia University Irving Medical Center (2020), more than 29 % of high school students surveyed admitted that they were targets of cyberbullying in the past year.Digital detox, which refers to a period of time that teenagers stay away from social media, is believed to have the potential benefits for teenagers' mental health including decreased symptom of depression and anxiety and better sleep precison (Hunt et al. 2018; Wilmer and Chein 2016).However, teenagers still need to be careful when applying digital detox since there are pressures coming from societies and their peers. Furthermore, school and community programs have succeeded in promoting healthy digital ridges and limits. Overall, teenagers should choose to use social media with balance in order to boost their mental health.

The introduction of machine learning in digital pathology has deeply impacted the field, especially with the advent of whole slide image (WSI) analysis. In this review, we tried to elucidate the role of machine learning algorithms in diagnostic precision, efficiency, and the reproducibility of the results. First, we discuss some of the most used tools, including QuPath, HistoQC, and HistomicsTK, and provide an updated overview of machine learning approaches and their application in pathology. Later, we report how these tools may simplify the automation of WSI analyses, also reducing manual workload and inter-observer variability. A novel aspect of this review is its focus on open-source tools, presented in a way that may help the adoption process for pathologists. Furthermore, we highlight the major benefits of these technologies, with the aim of making this review a practical guide for clinicians seeking to implement machine learning-based solutions in their specific workflows. Moreover, this review also emphasizes some crucial limitations related to data quality and the interpretability of the models, giving insight into future directions for research. Overall, this work tries to bridge the gap between the more recent technological progress in computer science and traditional clinical practice, supporting a broader, yet smooth, adoption of machine learning approaches in digital pathology.
An rVPM-Based Aerodynamic Hybrid Optimization Method for Coaxial Rotor with Differentiated Upper and Lower Blades in Both Hover and High-Speed Cruising States

Published: June 2024

To enhance the performance of rigid coaxial rotors across both hovering and high-speed cruising conditions, this study develops a novel aerodynamic optimization method that differentiates between the upper and lower rotors. Utilizing the lifting line and reformulated viscous vortex particle method (rVPM), this approach models the complex wake fields of coaxial rotors and accurately assesses the aerodynamic loads on the blades. The optimization of geometric properties such as planform configuration and nonlinear twist is conducted through an innovative solver that integrates simulated annealing with the Nelder–Mead algorithm, ensuring both rapid and comprehensive optimization results. Comparative analyses demonstrate that these tailored geometric adjustments significantly enhance efficiency in both operational states, surpassing traditional methods. This research provides a strategic framework for addressing the varied aerodynamic challenges presented by different flight states in coaxial rotor design.

Zinc (Zn) is crucial for both plant metabolism and human nutrition, with its deficiency being a global health concern. Strategies to increase its availability in food, such as agronomic biofortification, have gained prominence. This study evaluated the impact of foliar spraying of Zn [at full bloom stage: 0 (control) and 600 g ha−1, as ZnSO4⋅7H2O] on the nutritional quality of cowpea (Vigna unguiculata L. Walp.) grains. Field experiments involving 20 cowpea genotypes were carried out over two seasons in a Typic Quartzipsamment under a no-tillage system. The photosynthetic responses of cowpea plants and the concentrations of Zn, amino acids, sucrose, total sugars, and storage proteins (glutelin, albumin, prolamin, and globulin) in grains were analyzed. All genotypes showed enrichment of Zn in grains in response to ZnSO4⋅7H2O application compared to untreated plants. Foliar spraying of ZnSO4⋅7H2O during initial grain filling was ideal for increasing Zn concentration in grains and improving plant physiological processes. Additionally, Zn fertilization led to higher concentrations of storage and total amino acids and proteins in the grains, supporting the rational application of Zn in cowpea production to improve the nutritional quality of grains and increase plant productivity.
