Italian Adolescent Gambling Behaviour: Psychometric Evaluation of the South Oaks Gambling Screen: Revised for Adolescents (SOGS-RA) Among a Sample of Italian Students

Since no Italian validated instrument focuses specifically on the measurement of pathological gambling in very young people, with this study, we aim to adapt an international instrument (SOGS-RA) and assess its psychometric properties in a sample (n = 14.910) of young Italian students aged between 15 and 19 years. Cross-cultural adaptation of the instrument was performed through translation, synthesis of translation, back-translation, expert committee review, and pre-testing. The kappa statistic for test–retest concordance ranged from 0.53 to 0.80. Internal validity was assessed by the MCA that identified one principal component with eigenvalue equal to 3,875: the Divgi index and very simple structure analysis also pointed out one common factor, so uni-dimensionality of the SOGS-RA was accepted. Moreover the SOGS-RA was found to have acceptable internal consistency (α = 0.780). Cronbach’s alpha was also assessed separately among males and females (respectively 0.786 and 0.707). The SOGS-RA was assessed in relation to gambling frequency, alcohol and drug use: Chi squared test revealed a strong association both for males and females with gambling frequency (p value ≤ 0.0001), frequent use of illicit drugs (for each drug p value ≤ 0.0001) and having had 3 or more occasions of binge drinking in the last month (p value ≤ 0.0001). At the end we can say that, the results of our study suggest that the SOGS-RA screen may be useful to assess at-risk or problem gambling for both genders in comprehensive youth surveys.     

Identifying Environmental and Social Factors Predisposing to Pathological Gambling Combining Standard Logistic Regression and Logic Learning Machine

Identifying potential risk factors for problem gambling (PG) is of primary importance for planning preventive and therapeutic interventions. We illustrate a new approach based on the combination of standard logistic regression and an innovative method of supervised data mining (Logic Learning Machine or LLM). Data were taken from a pilot cross-sectional study to identify subjects with PG behaviour, assessed by two internationally validated scales (SOGS and Lie/Bet). Information was obtained from 251 gamblers recruited in six betting establishments. Data on socio-demographic characteristics, lifestyle and cognitive-related factors, and type, place and frequency of preferred gambling were obtained by a self-administered questionnaire. The following variables associated with PG were identified: instant gratification games, alcohol abuse, cognitive distortion, illegal behaviours and having started gambling with a relative or a friend. Furthermore, the combination of LLM and LR indicated the presence of two different types of PG, namely: (a) daily gamblers, more prone to illegal behaviour, with poor money management skills and who started gambling at an early age, and (b) non-daily gamblers, characterised by superstitious beliefs and a higher preference for immediate reward games. Finally, instant gratification games were strongly associated with the number of games usually played. Studies on gamblers habitually frequently betting shops are rare. The finding of different types of PG by habitual gamblers deserves further analysis in larger studies. Advanced data mining algorithms, like LLM, are powerful tools and potentially useful in identifying risk factors for PG.

Mental illness and problematic sexual behaviors. A review of the recent literature

Advanced practice nurses and other health care professionals have increasingly been working with individuals with mental illnesses who also have a history of sexual misconduct. Unfortunately, due partly to minimal research on the subject--especially in the nursing field--these professionals are addressing the needs of this population without adequate preparation. This article provides an overview of mental illness and problematic sexual behaviors (MI/PSB) and highlights the importance of additional research for the MI/PSB population as a subgroup of sex offenders.     

Revised MRP for reducing inventory level and smoothing order releases: a case in manufacturing industry

Although material requirement planning (MRP) systems are widely used in manufacturing companies, they exhibit significant drawbacks. Rev MRP algorithm has been developed in order to reduce the system nervousness, generate a more regular pattern of order released and lower inventory levels. The aim of this paper is to test the Rev MRP algorithm on the case of one of the largest Italian manufacturing companies of home appliances. The company provided three sets of real data, referring to three different runs of their MRP. Results showed that the Rev MRP outperformed the company’s MRP smoothing the production order releases, eliminating overshoots and drastically reducing the inventory levels along the supply chain, even in case of frequent forecasts updates.     

Corporate boards, audit committees and voluntary disclosure: evidence from Italian Listed Companies

This paper investigates the interplay between governance and disclosure in an agency setting, featured by concentrated ownership and high insider shareholders representation in the board. In this context, agency conflicts happen between large controlling shareholders and minority outside investors, with risks of private benefits exploitation. We regressed a voluntary disclosure index on seven governance variables related either to the board structure and functioning. The empirical evidence is provided by the Italian stock market. Our results suggest the presence of a complementary relationship between governance and disclosure. Diligent monitoring activity is associated with greater transparency to the outside. The findings are consistent with the view that internal and external control tend to be present at the same time, since the presence of one of them reduces the incentive for the controlling shareholders to limit the other. The empirical evidence also show that larger boards are not detrimental to outside shareholders, with regard to voluntary disclosure. The study can contribute to the understanding of the relationship between governance and disclosure in a particular agency setting. They might be of interest to practitioners and regulators, insofar as they are consistent with calls for more disclosure requirements in this agency setting.
