Abstract

We previously examined the efficacy of rTMS for major depressive disorder in an applied clinical practice. Clinical response was related to severity of depression as well as the rTMS instrument utilized suggesting a relationship to instrument or magnetic field parameters and individual factors. The effectiveness of repetitive transcranial magnetic stimulation (rTMS) in the treatment of major depressive disorder was further evaluated using Log-Rank statistics for time to remission outcomes. A follow-up retrospective medical records study was carried out on patients with major depressive disorder undergoing rTMS therapy at AwakeningsKC Clinical Neuroscience Institute (CNI), a suburban tertiary psychiatric clinic. Cox Proportional Hazard with Log-Rank statistics were applied and the time course to clinical remission was evaluated over a 6-week period with respect to age, gender, and depression severity. Clinical response was observed referencing two different rTMS instruments (MagVenture; NeuroStar). Time to remission studies of 247 case reports (N=98 males; N=149 females) showed consistently greater clinically defined remission rates after 6 weeks of rTMS treatment for patients using the MagVenture vs NeuroStar instrument. Patients previously admitted for inpatient psychiatric hospitalization exhibited higher response rates when treated with the MagVenture rTMS unit. Stepwise Cox Proportional Hazards Regression final model of time to remission included rTMS unit, inpatient psychiatric hospitalization and obese body habitus. Response to rTMS in applied clinical practice is related to severity of psychiatric illness and may require consideration of magnetic field parameters of the rTMS unit with respect to individual factors such as sex or body composition.

Abstract

Purpose

The Italian school-to-work transition (STWT) is astonishingly slow and long in comparison to the other EU countries. We analyze its determinants comparing the Italian case with Austria, Poland and the UK.

Design/methodology/approach

The analysis is based on a Cox survival model with proportional hazard. The smoothed hazard estimates allow us to identify the nonlinear path of the hazard function.

Findings

The authors reckon that the actual length of the transition to a stable job is around 30 months in Italy. Conversely, it is less than one year in the other countries. Women are particularly penalized, despite being on average more educated than men. Tertiary or vocational education at high secondary school strongly increases the hazard rate to a regular job. The smoothed hazard estimates suggest positive duration dependence at the beginning of the transition and slightly negative thereafter.

Practical implications

Stimulating economic growth and investing in education and training are important pre-conditions for shortening the transition.

Originality/value

Despite the duration of the STWT is one of the most important indicators to measure the efficiency of the STWT, it is not easy to measure. The authors build on their previous research work on this topic, but relaxing the assumption of a monotonic hazard rate and using the flexible baseline hazard approach to test for the existence of nonlinear duration dependence. Furthermore, they extend the analysis by including student-workers who attended a vocational path of education, in order to detect its effectiveness in allowing young people finding a job sooner.

Abstract

This paper examines how the macroeconomic environment affects the determinants of prepayment of mortgage loans from October 2004 to February 2020. For more accurate analysis, the authors define the timing of prepayment not only before the loan maturity but also at the time when 50% or more of the loan principal is repaid. The results show that, during the global financial crisis as well as the recent period of low interest rates, macroeconomic variables such as interest rate spreads and housing prices have a different effect compared to the normal situation. Also, significant explanatory variables, such as debt to income (DTI) ratio, loan amount ratio and poor credit score, have different effects depending on the macroenvironment. On the other hand, in all periods, the possibility of prepayment increases as comprehensive loan to value (CLTV) increases, and the younger the age, the shorter the loan maturity. The results suggest that, in the case of ultralong (40 years) mortgage loans recently introduced to support young people purchasing houses, the prepayment risk can be, at least partially, migrated by offsetting the increase in prepayment by young people and the decrease in prepayment due to long loan maturity. In addition, this study confirms that the accelerated time failure model compared to the logit model and COX proportional risk model has the potential to be more appropriate as a prepayment model for individual borrower analysis in terms of the explanatory power.

In this paper, the authors study the failure of Russian banks between 2012 and 2019.

Abstract

Purpose

In this paper, the authors study the failure of Russian banks between 2012 and 2019.

Design/methodology/approach

The authors analyze the entire population of Russian banks and combine a logit model with the survival analysis.

Findings

In addition to the usual determinants, the authors find that not-failed banks have higher levels of fulfillment of the Central Bank requirements of solvency, liquidity, provide fewer loans to their shareholders and own more shares of other banks. The results of this study suggest an asymmetric effect of the strategic orientation of banks: whereas the proportion of deposits from firms is negatively related to the probability of failure, the loans to firms are positively related to bankruptcies. According to this research, the fact of being controlled by a foreign bank has a significant negative relationship with the likelihood of failure and moderates the effect of bank size, performance and growth on the bankruptcy likelihood.

Practical implications

On the whole, the results of this study support the new Central Bank rules, but show that the thresholds imposed by the Russian regulator actually do not make a difference between failed and not failed banks in the short and medium term.

Originality/value

The authors specially focus on the effectiveness of new rules issued by the Central Bank of Russia in 2013.

Abstract

Purpose

Economic integration of refugees remains a challenge for developed countries. Although refugees differ greatly from labor migrants in available resources and motivation toward self-employment, prevailing studies on minority and ethnic entrepreneurship tend to lump these different categories of migrants together. Based on theories of migrants’ economic embeddedness, the purpose of this paper is to analyze the extent to which family- and kinship-based resources affect self-employment duration among refugees and labor migrants.

Design/methodology/approach

Based on Cox regression models, this longitudinal study estimates the self-employment duration of 10,519 refugees and 2,503 labor migrants starting businesses in Sweden in the period 2006–2012.

Findings

Results reveal that while refugees are at a disadvantage to labor migrants in terms of self-employment duration, their higher level of family embeddedness in part helps them overcome these disadvantages. For refugees but not for labor migrants, co-location in an ethnic enclave also lowers the risk of them becoming unemployed after a spell in entrepreneurship.

Originality/value

This original paper provides empirical and theoretical contributions to research on migrants’ self-employment success. It also discusses contributions for research on entrepreneurs’ social embeddedness and refugees’ entrepreneurship.

Abstract

Purpose

This study aims to find how the turnover of host country nationals (HCNs) would be affected by the knowledge transfer from a headquarter to a subsidiary. Knowledge transfer in a multinational corporation (MNC) has been discussed as a critical factor in the MNC’s success. Because HCNs are essential to synergizing with a new knowledge inflow during this knowledge transfer process, their turnover entails negative consequences such as knowledge loss.

Design/methodology/approach

This paper empirically tests the unbalance between knowledge received (KR) and absorptive capacity (AC) as the most critical organizational predictor by using the secondary longitudinal records and survey data of 4,915 employees. Multilevel survival analysis is used to calculate the individuals’ turnover hazard.

Findings

While finding that the primary effect of transferred knowledge is to reduce turnover, the study demonstrates the unbalance between a subsidiary’s AC and KR increases the likelihood of HCNs’ turnover within the organization. The authors also recognize the possibility of nonlinear trends of KR and AC on the turnover hazard.

Originality/value

The authors answer how knowledge transfer shapes a subsidiary’s work environment to prevent or increase turnover, which has been barely examined for HCNs who comprise the crucial demographic group in knowledge transfer. To enhance the originality further, this study empirically observes the actual turnover of HCNs with a conceptually comprehensive view incorporating both learning and political approaches.

Abstract

Purpose

This article will select 25 years of subdivided data to perform Kaplan–Meier survival analysis on the export trade relations of Chinese wooden flooring, use discrete-time cloglog models to analyze influencing factors, use logit and probit models to test the robustness, and try to systematically reveal the duration of China's wood flooring export trade and its influencing factors.

Design/methodology/approach

This study used Kaplan–Meier survival function estimation method. In the survival analysis, survival function and hazard rate function are often used to characterize the distribution of survival time.

Findings

The continuous average export time of China's wooden flooring is relatively long, about 14 years. China's wooden flooring has a negative time dependency. After the export trade exceeds the threshold value of 15 years, the failure rate of trade greatly decreases, which has a “threshold effect.” Gravity model variables have a significant impact on the duration of China's wooden floor export.

Originality/value

Studying the duration of forest products trade is of great significance for clearing deep-level trade relations and promoting sustainable development of forest products trade.

Abstract

Purpose

While there exist many surveys on the use stochastic frontier analysis (SFA), many important issues and techniques in SFA were not well elaborated in the previous surveys, namely, regular models, copula modeling, nonparametric estimation by Grenander’s method of sieves, empirical likelihood and causality issues in SFA using regression discontinuity design (RDD) (sharp and fuzzy RDD). The purpose of this paper is to encourage more research in these directions.

Design/methodology/approach

A literature survey.

Findings

While there are many useful applications of SFA to econometrics, there are also many important open problems.

Originality/value

This is the first survey of SFA in econometrics that emphasizes important issues and techniques such as copulas.

Abstract

Purpose

Globally, health problems are very common among prisoners. A mental state examination aims to help in recognising psychiatric problems among offenders and the possible association of these psychiatric issues with their committed crime. The legal-medical term “reduced criminal responsibility” refers to a weakened sense of reality and the ability to control one’s behaviour because of compromised mental health and without an evaluated need for forensic psychiatric hospitalisation. However, little is known about the actual need for the health care of prisoners with reduced criminal responsibility (PRCR). The purpose of this study was to explore treatment-related visits to prison by PRCR in Finland.

Design/methodology/approach

The research data comprise information on PRCR’s treatment-related visits and that of a matched control group (n = 222). Descriptive cross-tabulation with X²- and nonparametric Mann–Whitney U-tests and Cox regression analyses are applied.

Findings

The results show that almost every PRCR had at least one treatment-related visit during their sentences. Visits to a psychiatric hospital for prisoners, to the prison hospital and especially to a civil hospital are more common among PRCR. The need for treatment appears significantly earlier in their sentences.

Originality/value

These findings demonstrate the PRCR’s greater need for access to health services and the need for further development between the Health Care Services for Prisoners, Prison and Probation Service of Finland and public health and social services in Finland. More exploration of the medical reasons and locational distribution of the vast amount of civil hospitalisation is needed.
