Abstract

Cox’s proportional hazards model (PHM) has been widely applied to the analysis of lifetime data. It involves covariates influencing the failure of products. Regarding the covariates as discrete random variables, the probability model is reduced to a mixture of PHM. This article presents a statistical procedure to estimate model parameters in the mixture of PHM. The estimation procedure is developed in a parametric framework when not only complete sets of field data but also incomplete ones are given. The expectation‐maximization algorithm is employed to handle the incomplete data problem. Simulation results are presented to illustrate the accuracy and some properties of the estimation results.

Abstract

The Hanbo (meaning Korean treasure) scandal or “Hanbogate” occurred on January 23, 1997, with the bankruptcy of Hanbo Iron and Steel Company, the second largest steel company and 14th largest conglomerate in South Korea, as its debt had accumulated to US$5.6 billion. Hanbo's bankruptcy triggered an investigation by the Public Prosecutor's Office that resulted in the imprisonment for 15 years of Hanbo's founder, Chung Tae-Soo, for bribing politicians and bankers to pressure banks to extend hugh bank loans to Hanbo. Nine other persons were also convicted including Chung's son, who was jailed for three years for bribery and embezzlement, and Kim Hyun-Chol, the second son of President Kim Young-Sam, who was sentenced to three years jail and fined US$1.5 million (New York Times, 1997).

Abstract

Purpose

Workplace loneliness has become a concern in diverse work settings. However, workplace loneliness research is in its early stages of development and not much is known about the effects of it on organizations and its members, especially in police organizations. The purpose of this study is to investigate the relationships between workplace loneliness, anxiety, happiness, task performance, and organizational citizenship behavior (OCB). Data from police officers in Korea were used to test these relationships.

Design/methodology/approach

Using a three-wave time-lagged procedure, the study sample consisted of 227 police officers in South Korea from one regional police headquarters (Yongin Dongbu Police Station) and four substations in the Yongin region. The study tested parallel mediation of anxiety and happiness in the relationships between workplace loneliness and workplace outcomes using the PROCESS macro (Model 4) for SPSS 26.

Findings

The regression analyses with bootstrapping results indicated that police officers' anxiety and happiness served as mediating mechanisms linking workplace loneliness with task performance and OCB.

Originality/value

The police force is a very significant facet within society. However, research has not yet investigated loneliness in the police context. Thus, the study investigated the proximal and distal effects of workplace loneliness by associating workplace loneliness with task performance and OCB via anxiety and happiness.

Abstract

This study attempts to introduce South Korea's unique experiences of civic operations made in Iraq and Lebanon. Koreans approached it with extreme caution since they are seeing through two different lenses: “paying back syndrome” from the Korean War experiences is colliding with the “Vietnam syndrome” from the experiences of Vietnam War. Expanding its regional role through revitalizing PKOs is not an easy job for the ROK government despite the fact that President Lee has committed himself to increase its efforts since his campaign days. South Korea recently decided to send its KDX-II type destroyer to Somalia for joining the maritime peacekeeping while people in Korea strongly suspect that the Obama administration would soon request to send its troops to Afghanistan as a part of International Security Assistance Force (ISAF). As the Korean society is getting democratized, progressive NGOs have been opposing the government decision to send forces to assist the U.S. war efforts in Iraq and Afghanistan. It remains to be seen how President Lee persuades people to bear the burden and endure sacrifices. At least, four problems need to be addressed for Korea to become a major troop-contributing country (TCC): first, Korea needs to enact laws to deal with South Korea's participation in the UN PKOs. Second, Korea needs to find a way to include civilian experts in future activities of UN PKOs. Third, it needs to increase the budget and size of standby forces. Lastly, it needs to educate people to understand why Korea has to contribute further to make a safer world. It remains to be seen whether South Korea will continue to focus on its stabilization and reconstruction efforts without sending its combat troops.

Abstract

Purpose

This study aims to analyze the returns obtained from companies with strong growth potential (growth stocks) and the returns from companies with quite low stock prices, but with high value (value stocks).

Design/methodology/approach

The sample comprises monthly data, from January 2002 to December 2016, from seven countries, Germany, France, Switzerland, the UK, Portugal, the USA and Japan. The authors have used linear regression models for three different periods, the pre-crisis, subprime crisis and post-crisis period.

Findings

The results point out that the performance of value and growth stocks differs from different periods surrounding the global financial crisis. In fact, for six countries, value stocks outperformed growth stocks in the period that precedes the subprime crisis and during the crisis, this tendency remained only for France, Portugal and Japan. This trend changed in the period following the crisis. The results also show that investor sentiment has a robust significance in value and growth stock returns, mostly in the period before the crisis, highlighting that the investor sentiment is more significant in the moments that the value stocks outperformed.

Originality/value

As far as the authors know, this is the first work that, taking into account the future research lines of Capaul et al. (1993), investigates whether the results obtained by those authors remain current, meeting the authors’ challenge and covering the gap of recent studies on the performance of value and growth stocks. Besides, the authors have introduced a new country, heavily punished by both the global financial crisis and the sovereign debt crisis to understand whether there are significant differences in investment styles and whether this is related to the different economies. Also, in this context, the authors were pioneers in adding investor sentiment as an exogenous variable in the influence of stock returns.

Abstract

Purpose

Ireland is viewed as the shining base for Catholicism. That image is shattered as survivors revealed the abuse in the Magdalene Laundries and Mother and Baby Homes, and sexual abuse by priests. This study aims to examine image repair efforts by the Pope during his August 2018 visit.

Design/methodology/approach

Examined against the Letter of His Holiness released days earlier, this study evaluates all the Pope's speeches during his visit to Ireland using the image repair theory (Benoit and Pang, 2008) as its theoretical lens.

Findings

Pope Francis used the evasion of responsibility strategy to address the Magdalene Laundries and Mother and Baby Homes scandal and denial, corrective action and mortification for sex abuse crisis.

Research limitations/implications

Addresses call by Ferguson et al. (2018) to examine the consistency and effectiveness of strategies.

Practical implications

Beyond rhetoric, stakeholders would be looking to organizational leaders to provide relief and concrete steps to recover from their pain.

Originality/value

A leader's narratives represent the organization's narratives; thus, insights from this study can help leaders plan what they should say when conducting image repair. It is not just their own reputations that are on the line but, in this case, it is also the reputations of the people they represent

Abstract

Purpose – The purpose of the research was to examine the process of new teacher evaluation policy development in South Korea, in order to gain insight into how a controversial policy could be established in education. Research questions were about the process of the policy development, political actors involved and their influences, and the meaning of teacher evaluation in the newly established teacher evaluation policy.Methodology – The study uses a qualitative and descriptive-analytical process from a hermeneutics perspective that views policy as text to be interpreted. This perspective allows policy to be connected to a larger social context through interpretations of text. The main data sources included policy documents, statements by various organizations, research reports, and public media artifacts produced between 2000 and 2012. For data analysis, constant comparison and content analysis methods were used.Findings – The findings show that the process of developing a teacher evaluation system demonstrated an unsuccessful attempt to apply the Habermasian notion of discursive democracy. Relevant stakeholders were invited to deliberate on the reform, but official meetings ended prematurely without consensus. In the end, the government proceeded without full support of any stakeholders. During the deliberation process, teacher organizations and parent groups demonstrated conflicting perspectives on teacher work and the new evaluation system only partially accommodated both perspectives. The effectiveness of the new evaluation system remains to be researched.Value – The policy development process and the evaluation system shown in this study should inform similar efforts in other contexts.
