The purpose of this paper is to estimate the impacts of women's education on the mean age of women at first birth (denoting the timing of fertility) and total fertility rate (TFR, denoting the level of fertility) using cross-country panel data.

The estimations proceed in two steps: first, the timing and level of fertility regressions are separately estimated, and second, two regressions are estimated at the same time as a form of a system equation to accommodate the correlations between error terms.

It is found that a higher women's education tends to delay of child birth or family formation. In addition, there exists a negative relationship between the female secondary school enrollment ratio and TFR, meaning that the opportunity costs of childbearing and rearing increases when the level of women's education enhances. However, the authors have also found that the impacts of women's higher education on TFR is statistically insignificant in a few cases of estimations without sample selections.

Fertility decline is a shift of childbearing to older ages. The delay of child birth or family formation is the major cause of the recent fertility decline, because a late women's age at first birth reduces the chances of having any further children. This implies that the timing and level of fertility are highly correlated to each other. In particular, many studies showed that women's education and employment have been identified as major parameters for the increase in women's age at first birth. Nonetheless, little attention has been paid to an empirical analysis of the relationship between women's education and the timing of fertility. Therefore, this paper is an extension of previous studies, estimating the relationship between women's education and the timing and level of fertility at the same time.

During the planting process, agricultural products produce large amounts of greenhouse gas (GHG) emissions. This has placed tremendous pressure on sustainable global development. Many countries and regions in the world have adopted intensive subsistence cultivation methods when planting maize; however, limited studies exist on these methods. The main purpose of this research is to show the impact of climate change on maize yields and carbon footprint (CF) in South Korea over 10 years, find the proper operating method and promote the advanced combination of inputs for the sustainable development of maize farmers.

This study used survey data from the South Korea Rural Development Administration of 2010, 2014 and 2019 to estimate the CF of maize planting under intensive subsistence cultivation. Life-cycle assessment was used to determine the CF. Farmers were grouped according to significant differences in yield and GHG emissions. Linear regression was used to measure the dependence of the main contributors on the CF production and carbon efficiency.

In South Korean maize planting, N in chemical fertiliser was the most significant contributor to the CF and organic fertiliser was the most significant input. The use of chemical and organic fertilisers significantly affects the production of the CF and carbon efficiency. Households in the high-yield and low-GHG emission groups are more sustainable because they generate the least GHG when producing and earning through maize cultivation. Globally, maize production in South Korea has a relatively low CF and maize production produces fewer GHG.

This study provides information for policymakers to determine key operational options for reducing GHG emissions using intensive subsistence cultivation of maize production in South Korea and other countries.

Social commerce using social media has been on the rapid increase. Among various social commerce models, group-buying has become the mainstream. There is a paucity of research related to how customers perceive value in group-buying situations. This paper aims to examine and analyze various factors that influence perceived customer value in group-buying.

Data were collected using a survey on customers who had purchased a restaurant service deal on a group-buying site. A partial least squares technique was used to estimate the model.

Results show that perceived customer value affects customers’ group buying intentions and that all four antecedents of perceived value (low price, valence of experience, trust in social media and reputation of the group-buying site) have a significant influence. Implications and further research directions are discussed at the end of the paper.

This study provides valuable strategic implications for social commerce firms.

A lot of recent research has been focused on developing network mobility management to support the movement of a mobile network consisting of several mobile nodes. The IETF NEMO working group proposed the NEMO basic support protocol that defines a methodology for supporting such network mobility using bi‐directional tunneling between the home agent and the mobile router. However, this protocol has been found to suffer from the so‐called ‘dog‐leg problem’, and despite alternative research efforts to solve this problem, there are still limitations in the efficiency of real time data transmission and intra‐domain communication. Accordingly, the current paper proposes a new route optimization methodology that uses unidirectional tunneling and a tree‐based intra‐domain routing mechanism. As such, the proposed scheme can provide faster signaling and data transmission and be easily extended to support micro‐mobility without any additional extensions. The performance of the proposed scheme is also evaluated to demonstrate its efficiency.

The argument here is direct, if tentative. Thus, most available evaluative studies agree that OD applications, globally, have substantial success rates, but this seems ironic in light of the common domination of culturally relativistic views. Many observers urge the culture-boundedness of planned change which implies low OD success rates. This paper is one in a projected series of qualitative tests about whether the irony is only apparent. That is, this series proposes to test for the congruence of the basic OD normative framework with various cultural patterns that can be encountered in the global analysis of today’s organizations. A high degree of fit between the OD Work Ethic and more or less discrete ideational frameworks will help dissolve the apparent irony.

Here, the specific task involves testing the congruence of the “Confucian Work Ethic” with an OD normative framework. The latter may be viewed as the “target” against which the fit of the Confucian Work Ethic is tested in a qualitative sense. High success rates are reported for OD applications in Confucian settings, especially in Korea where Confucian ideas have a substantial prominence. Here, Confucian comparisons with the OD Ethic imply a “good fit,” which is consistent with the similarly high success rates in Korea as well as elsewhere.

From a recently published letter addressed to a well‐known firm of whisky manufacturers by Mr. JOHN LETHIBY, Assistant Secretary to the Local Government Board, it is plain that the Board decline to entertain the suggestion that the Government should take steps to compel manufacturers of whisky to apply correct descriptions to their products. The adoption of this attitude by the Board might have been anticipated, but the grounds upon which the Board appear to have taken it up are not in reality such as will afford an adequate defence of their position, as the negative evidence given before the Select Committee on Food Products Adulteration and yielded by the reports of Public Analysts is beside the mark. The introduction of a governmental control of the nature suggested is not only undesirable but impracticable. It is undesirable because such a control must be compulsory and is bound to be unfair. It would be relegated to a Government Department, and of necessity, therefore, in the result it would be in the hands of an individual—the head of the Department—and subject entirely to the ideas and the unavoidable prejudices of one person. It is impracticable because no Government or Government Department could afford to take up a position involving the recommendation of particular products and the condemnation of others. No Government could take upon itself the onus of deciding questions of quality as distinguished from questions merely involving nature and substance. A system of control, in order to be effective and valuable alike to the public and the honest manufacturer, must be voluntary in its nature in so far as the manufacturer is concerned, and must be carried out by an independent and authoritative body entirely free from governmental trammels, and possessing full liberty to give or withhold its approbation or guarantee.

The purpose of this paper is to present the North Korea policy pursued by the Moon Jae-in administration and discuss the possibility of a weakened alliance between South Korea and the USA.

This paper compares the North Korean policies and the ROK–US alliance under the Moon administration, analyzing the recent inter-Korean and North Korea–US summits, with a focus on the issues of denuclearization and establishing a peace regime.

This paper reveals that the approach taken by the Moon administration regarding North Korea is similar to that of North Korea and China, and that the ROK–US alliance is likely to weaken should there be any change concerning the North Korean nuclear issue.

Denuclearization takes place in accordance with the agreement between North Korea and the USA, there is a high likelihood of the ROK–US alliance weakening.

This study aims to analyze and synthesize literature on consumer privacy-related behavior and intelligent device-to-device interactions within the Internet of Things (IoT).

We conducted a systematic review using Elsevier’s Scopus database, focusing on studies published in English from 2000 to 2023. The review targeted articles within selected social sciences and business disciplines, specifically concerning consumer behavior in IoT contexts.

We categorized the privacy literature into three thematic clusters: legislation and policy, business implications and consumer behavior. Within the consumer behavior cluster, our analysis indicates a shift from general Internet and e-commerce privacy concerns prior to 2016, toward issues related to advertising and policy between 2017 and 2018, and increasingly toward pronounced concerns in technological systems, particularly IoT, from 2019 onwards. We identify eight distinct areas of privacy concern within IoT and propose a framework that links antecedents and privacy concerns to subsequent attitudes and behaviors. This framework highlights varying patterns of information disclosure and bridges theoretical constructs with empirical research in IoT privacy.

Originality lies in enhancing the Antecedents-Privacy Concerns-Outcomes (APCO) macro-model by integrating diverse theoretical perspectives on technological and individual-specific antecedents, alongside privacy concerns and beliefs. This comprehensive integration enriches the framework, enabling it to predict and categorize consumer behavior in IoT environments more effectively. The revised model provides a robust tool for understanding privacy-related behavior within the IoT, significantly enriching its theoretical relevance and practical applicability.

This study examines the effect of occupational stress on turnover intention of employees working in the banking industry. The authors examine the mediating effects of service climate and emotional regulations of the employees in the relationship between occupational stress and intention to leave the organization.

This study followed stratified sampling technique for data collection from employees of ten commercial banks based on the banks' financial performance of top 5 and bottom 5 out of 27 banks. Data were collected at 2 stages, first from 465 employees for occupational stressors and second from 408 employees among the participants in the first stage for turnover intention, service climate and emotional regulation. Harman’s one-factor test was conducted to examine the common method bias. Confirmatory factor analysis (CFA), regression analysis and Preacher and Hayes Process Macro approach were used to examine mediation effect.

Three factors, namely workload (WL), role ambiguity and growth opportunity expectations were identified as the occupational stressors in the banking industry, predicting a positive relation of overall occupational stress to the intention to turnover. Service climate and the employees’ emotion regulation ability mediate the relationship between stress and turnover intention. Results also revealed no significant role of control variables in predicting occupational stress and turnover intention.

This study implies that the WL, role ambiguity and growth opportunity expectations of the employees cause stress in employees which may lead to have turnover intention. In order to get success in competitive environment, managers of banking industry can address stressors by enhancing service climate and formulating policies and programs to strengthen the emotion regulation which is evidence to strengthen the reciprocity approach of social exchange theory in employees’ commitment.

This study contributes to the social exchange theory and attempts to fulfill the gaps in empirical research on personnel psychology, human capital\ and organization management in developing countries.
