The influence of green human resource management on environmental performance: Exploring the differential effects of green work engagement and moral reflection
Authors: Yang Chaoqiao , Chen Chun-Shuo , Wei Li-Wei
Published: October 2024

This study investigates the impact of the implementation of Green Human Resource Management (GHRM) on the environmental performance of higher education institutions from the perspective of the Ability-Motivation-Opportunity (AMO) theory. A purposive sampling approach was employed to collect 670 questionnaires from the academic and administrative staff of higher education institutions in Thailand. The findings of the research demonstrate that GHRM enhances the environmental performance of higher education institutions. Moreover, GHRM contributes to this enhancement by positively influencing employees’ green work engagement, thereby improving the environmental performance of the institutions. Additionally, employees’ moral reflection positively moderates the relationship between GHRM and green work engagement. This study aspires to construct a holistic research framework, offering new practical and theoretical insights into GHRM, which, in turn, provides meaningful guidance for the sustainable development of global higher education institutions.
Pathways to corporate green technological innovation: An analysis from the perspective of dynamic capabilities
Authors: Du Jianhang , Ganbaatar Batkhuyag , Xiong Ni
Published: October 2024

Green technological innovation has become a pivotal tool for driving economic restructuring and achieving environmental sustainability. However, in the face of complex and volatile market and policy environments, a critical question remains: how can enterprises effectively select and implement innovation pathways to address environmental turbulence? Drawing on data from 14,751 Chinese listed companies from 2012 to 2022, this study employs dynamic capabilities theory and a fixed-effects panel model to examine the impact of dynamic capabilities on firms’ choice of green innovation pathways. Results show a significant positive influence of dynamic capabilities on green innovation, although this effect varies depending on the research and development model and the level of environmental turbulence. Firms with high dynamic capabilities tend to favor independent research and development, with an effect coefficient of 0.778 (p<0.01); firms with moderate dynamic capabilities benefit more from cooperative research and development, with a coefficient of 0.045 (p<0.01); and firms with lower dynamic capabilities primarily pursue green innovation through technology transactions, with a coefficient of 0.052 (p<0.01). Furthermore, environmental turbulence significantly moderates the relationship between dynamic capabilities and green innovation negatively, with an interaction coefficient of -0.088 (p<0.05), indicating that environmental uncertainty weakens the positive impact of dynamic capabilities.These findings suggest that firms can select suitable research and development models aligned with their level of dynamic capabilities and adopt flexible innovation strategies to effectively manage environmental turbulence. This study proposes the following policy recommendations: enterprises should strengthen their dynamic capabilities, particularly in knowledge acquisition, resource integration, and adaptability to environmental changes, to enhance their green innovation capacity. Additionally, the government should increase policy support for green technological innovation by offering financial subsidies, tax incentives, and intellectual property protections, helping enterprises maintain their innovation momentum amid environmental turbulence.
FORM FACTORS AND VOLUME MODELS FOR ESTIMATING TREE BOLE VOLUME OF MAHOGANY AT COMMUNITY FORESTS IN CENTRAL JAVA
Authors: Tiryana Tatang , Khasanah Lailatul , Priyanto Priyanto , Rahaju Sri
Published: October 2024

Form factors and volume models are often be used in the estimation of tree volumes. However, a few studies have developed and evaluated the accuracy of form factors and volume models for estimating tree volumes of community forests. This study aimed to formulate form factors and volume models and assess their prediction accuracy for estimating tree bole volumes of mahogany at community forests in Central Java. This study used 120 sample trees with diameters of 6–38 cm to formulate artificial and absolute form factors and to develop tree bole volume models. These form factors coupled with bole height and total height were used in simple volume equations. Regression analyses were used to develop volume models using the diameter and total height as predictors. The simple volume equations and volume models' prediction accuracy was evaluated using a cross-validation dataset and independent dataset (30 sample trees). The artificial form factor (0.68 ± 0.11) of mahogany, which was higher than the absolute form factor (0.46 ± 0.09), provided accurate estimates of tree bole volumes when it was used with the bole height instead of the total height. The volume model that uses diameter and total height produced the most accurate estimates, while the volume model that uses diameter alone provided the most practical yet reliable tool for estimating tree bole volumes of mahogany. The results of this study are useful for improving community forest management.

The pharmaceutical industry is key to the survival of the human race, but equally becoming increasingly susceptible to global disruptions. In Nigeria, records have shown that the industry is plagued with several problems, inclusive of low employee productivity, poor market share, low innovation performance, poor and marginal sales growth and low profitability, which are likely a result of a lack of strategic flexibility in the face of increasing environment turbulence and intense competition. Despite efforts from researchers, the moderating role of supply chain agility has been largely overlooked in the literature. Therefore, this study examines the moderating role of supply chain agility on the relationship between strategic flexibility (resource flexibility, coordination flexibility, proactive flexibility, reactive flexibility and futurity) and organisational performance. A survey research design was used to collect data from 642 management and senior staff employees of six pharmaceutical companies listed on the Nigerian Exchange Group. A total enumeration method was adopted for the study, with a well-structured adapted questionnaire, having Cronbach’s alpha reliability coefficients ranging from 0.725 to 0.945. Partial Least Squares Structural Equation Modeling (PLS-SEM) was chosen to achieve the research goal. The PLS-SEM analysis revealed that strategic flexibility positively affects organizational performance (β = -0.093, p> 0.050, Q2 = 0.644). However, supply chain agility negatively moderates this effect, indicating that while agility is beneficial independently, it can counteract the positive impact of strategic flexibility when combined. The study recommended that the management of pharmaceutical companies in Nigeria should pay serious attention to strategic flexibility as an organizational capability that can enhance performance in the face of increasing uncertainties in and unpredictability nature of the business environment.

IPTW and DR Estimators: Advancing towards the Adoption of Methodologies for Estimating Causal Treatment Effects in Observational Studies
Authors: Xia Pengbo
Published: October 2024

The propensity score refers to the likelihood of a subject being selected for intervention, given their observed baseline covariates. By assigning different weights to academic disciplines based on the reciprocal probability of receiving treatment, there will be a synthetic sample where the assignment of treatment is not influenced by baseline factors that were measured. Utilizing inverse probability of treatment weighting (IPTW) through the propensity score enables people to assemble unbiased or objective estimates regarding average treatment effects. In order to estimate the causal relationship between an exposure and an outcome, the second notion of doubly robust estimation combines an outcome regression with a propensity score model. Only when the statistical model is appropriately stated can unbiased estimates be obtained using the propensity score approach and outcome regression separately. However, even if only one of the two models is correctly specified, an unbiased estimator for the effect can be obtained by employing the doubly robust estimator. This introduction to inverse probability of treatment weighting and doubly robust estimators includes conceptual overviews, an application to students’ performance in high school, as well as discussions based on the project.

The Impact of Foster Care on Child Development: The Role of Sibling Separation
Authors: Liu Ziwen
Published: October 2024

This paper explores the impact of sibling relationships on children’s development within the foster care system, focusing particularly on how sibling separation affects children of different ages emotionally, cognitively, and socially. To address this, the study synthesizes existing literature and theoretical models by combining the developmental stages of children with the role of siblings in child development. Findings reveal that sibling separation at different ages leads to distinct developmental challenges: infants experience severe disruptions in attachment and emotional regulation, middle childhood separations hinder cognitive and social skills development, and adolescent separations result in long-term relational and identity challenges. Previous research underscores the importance of maintaining sibling bonds in foster care, highlighting that these relationships can provide crucial emotional support and stability, mitigating the adverse effects of family disruptions. This study emphasizes the necessity for age-appropriate actions and support services in foster care to minimize the detrimental impacts of sibling separation and promote healthy development. Additionally, it calls for further longitudinal studies to track the developmental trajectories of children separated from their siblings and consider variables such as age differences between siblings and the dynamics of step-sibling relationships. This comprehensive understanding is essential for informing policies and practices that enhance the well-being of children in foster care.
The Relationship Between Government Welfare Policies and Employment Rates: An In-Depth Analysis
Authors: Zhang Conghuan
Published: October 2024

This study examined the effects of social programs implemented by governments in China, the US, and Norway on employment rates. Welfare policies are essential for mitigating the problems of unemployment, poverty, and social inequality that the government faces and for fostering social stability. Using case studies and empirical data, this study uses a comparative analytical approach to investigate how various welfare regimes impact job results. According to the study’s findings, employment has decreased in China even while social spending has increased steadily. This might be because of a lag between the country’s economic transformation and the execution of its policies. Although welfare spending has expanded dramatically in the United States, employment growth has been modest, implying that welfare dependency may worsen rather than provide work prospects. Conversely, Norway’s welfare system is distinguished by substantial worker support and high social spending, both of which are positively connected with growth and stability in employment. The study concludes that, although welfare policies are essential to social security, their formulation and execution need to be carefully considered in order to encourage employment and prevent unforeseen outcomes like dependency or decreased labor force participation. The significance of welfare system optimization in promoting social justice and economic stability while attending to the needs of disadvantaged populations is emphasized by this study

Reverse Transfer in Chinese Adolescents: Implications for Language and Cultural Identity Preservation
Authors: Liu Yixuan
Published: October 2024

This literature review examines the phenomenon of reverse transfer (RT) among Chinese adolescents, focusing on its implications for the preservation of their mother tongue and cultural identity. Reverse transfer, a subtype of cross-linguistic influence (CLI), occurs when a later-acquired language affects an earlier one, challenging the traditional view of language learning as unidirectional. The study of RT is particularly pertinent for Chinese adolescents, who are often exposed to multiple languages due to globalization and educational policies, potentially impacting their linguistic and cultural heritage. This article employs the method of a formal literature review. The review synthesizes recent research on RT among Chinese adolescents, with a focus on how additional languages, particularly English, influence their Mandarin proficiency. Findings suggest English has had a significant impact on the mother tongue of Chinese adolescents. Moreover, RT’s impact extends to cultural identity, with some adolescents navigating multicultural spaces effectively, while others experience cultural dissonance, suggesting RT’s role in shaping cultural self-perception and connections to Chinese heritage. The paper underscores the complexity of RT’s effects on language and cultural identity, highlighting the need for educational practices that support multilingual development without compromising the mother tongue. It concludes with a call for longitudinal studies to explore the long-term effects of RT on language and cultural identity among Chinese adolescents, aiming to inform language education and cultural preservation policies.

Published: October 2024

As a matter of fact, the hunt for gravitational waves have been under the spotlight since LIGO researchers took home the Nobel Prize. In reality, different from the laser interferometers used by LIGO, pulsar timing arrays are also feasible ways to detect gravitational waves. With this in mind, this article will mainly focus on how pulsar timing arrays could detect gravitational waves as well as its achievements so far. To be specific, pulsar timing arrays consisted of rotating pulsars in space, and their regular burst of radio waves serve as stopwatches. When gravitational waves pass by, the frequency at which human beings’ receiving radio waves will change at the same time. Pulsar timing array projects around the world have been busy recording pulsars up to now, but more discoveries will come out soon. They also utilized their data to verify previous calculations such as the Helling-Downs curve. According to the analysis, the current limitations and prospects are demonstrated.

Exploring Implicit Biases Towards Disadvantaged Groups: An IAT Approach
Authors: Hu Wenjia
Published: October 2024

Disadvantaged groups, such as individuals with disabilities, orphans, and the impoverished, constitute a significant portion of the population across the globe. These groups encounter numerous challenges in their daily lives. A societal goal should be to support disadvantaged groups in keeping pace with social development and overcoming their hardships. Prejudice, exclusion, and discrimination persist, hindering the integration of these groups into mainstream society. This study seeks to examine public attitudes towards disadvantaged groups using the implicit association test (IAT), which measures implicit acceptance or exclusion based on reaction times. Compared to surveys or interviews, the IAT can more accurately reveal an individual’s unconscious biases and provide quantitative results. In this study, a set of ten positive attribute words, ten negative attribute words, ten conceptual words related to disadvantaged groups, and ten conceptual words related to non-disadvantaged groups were utilized. A total of twenty participants were recruited to attend the trial. The data analysis revealed a general tendency for implicit rejection of disadvantaged groups, with a D value of 0.92, which is very close to the maximum threshold of [-1, 1]. Moreover, the reaction time between the compatible group and incompatible group is significantly different. The results found no statistical difference in attitudes between females and males. The findings of this study highlight the implicit perceptions of disadvantaged groups and call for a societal shift away from exclusion, prejudice, and discrimination. It emphasizes the need for a more equitable, inclusive, and respectful approach towards these groups, advocating for a societal ethos that fosters understanding and support.
