Abstract

Purpose

Recent developments in the psychometric assessment of youth psychopathic traits suggest that the inclusion of a conduct disorder (CD) factor to the traditional three factors of the psychopathy construct may improve the incremental validity of these measures. The purpose of the current study is to examine whether the addition of a CD factor incrementally improves the ability of the Youth Psychopathic Traits Inventory Short version (YPI-S) to predict criminal recidivism.

Design/methodology/approach

A longitudinal quantitative research design was used with a sample detained male youth (N = 214, Mage = 16.4 years, SDage = 1.3 years).

Findings

Results using the area under the curve analysis suggest that the inclusion of a CD factor slightly improves the capacity of the YPI-S to predict one-year general criminal recidivism, but it does not significantly increase its capacity to predict violent criminal recidivism. Results also indicate that a CD scale outperforms the YPI-S, even with an additional CD factor included, in terms of predicting one-year general and violent recidivism.

Practical implications

Self-reported youth psychopathic trait measures, even those that include a CD factor as a fourth factor, should be used with caution when the aim is to predict youth criminal recidivism.

Originality/value

To the best of the authors’ knowledge, this is the first study using a self-reported youth psychopathic traits measure with a CD factor to examine youth criminal recidivism.

Abstract

Purpose

The purpose of this study is to ascertain whether nonlinearities could be present in electricity loads observed in subtropical environments, where none or little heating is required, and whether threshold autoregressive (TAR)-type regime switching models could be advantageous in the modeling of those loads.

Design/methodology/approach

The actual observed load of a Brazilian regional electricity distributor from January 2013 to August 2012 was modeled using a popularly employed ARMA model for reference, and smooth and non-smooth TAR transition (non-linear) models were used as non-linear regime switching models.

Findings

Evidence of nonlinearities were found in the load series, and evidence was also found on the intrinsic resistance of this type of models to structural breaks in the data. Additionally, to reacting well to asymmetries in the data, these models avoid the use of exogenous variables. Altogether, this could prove to be a definite advantage of the use of such model alternatives.

Research limitations/implications

However, even if the present work may have been limited by the observation frequency of the available data, it appears TAR models appear to be a viable alternative to forecasting short-term electricity loads. Nonetheless, additional research is required to achieve a higher accuracy of forecast data.

Practical implications

If such models can be successfully used, it will be a great advantage for electricity generators, as the computational effort involved in the use of such models is not significantly larger than regular linear ones.

Originality/value

To our knowledge, this type of research has not yet been made with subtropical/tropical electricity load data.

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

The West African Republic of Guinea-Bissau has been unstable since gaining its independence in 1974. The 2014 presidential and parliamentary elections are being closely analyzed to study how the United Nations and the Guinean people have reacted to the outcomes of these elections. The paper aims to discuss these issues.

Design/methodology/approach

Sociological methodologies and a comparative approach have been used in this paper to understand why the elections in 2014 were so important in this country.

Findings

The author finds that stability is possible in Guinea-Bissau after years of political uncertainties.

Originality/value

Particular focus has been paid to studying the responses of specific aspects of society, including the youth population, the political elite, the main political party, the African Party for the Independence of Guinea and Cape Verde, the opposition parties and the army and whether these different groups will be able to cooperate after electing a sustainable and relatively wide-ranging government.
