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.     

The Effect of a Multicomponent Dual-Modality Exercise Program Targeting Osteoporosis on Bone Health Status and Physical Function Capacity of Postmenopausal Women

Purpose: Exercise is important for the prevention of osteoporosis and the reduction of fracture risk because it improves muscle mass and strength, besides improving balance. We evaluated the effect of a specific exercise program on bone mass and quality and physical function capacity in postmenopausal women with low bone mineral density. Methods: Participants (N = 125) underwent a bone mass (Dual X-ray Absorptiometry), bone quality (osteosonography), and physical functional capacity assessment. Fifty-eight of them took part in an 11-month exercise program (E), that included a multicomponent (strength, aerobic capacity, balance, joint mobility) dual-modality (on ground and in the water; alternating group and home-based exercise periods) exercise regimen. The others represented a control group (C) that did not exercise. After the exercise program all participants were reevaluated. Results: After the training program: femoral neck T-score significantly improved in E; C significantly decreased all bone quality (osteosonography) parameters, whereas E showed no differences; E significantly improved all the physical function capacity parameters, while most of them decreased or did not change in C. Conclusions: A specific exercise program targeting osteoporosis improves physical function capacity, reduces physiological bone loss, and maintains bone quality in low bone mineral density postmenopausal women.

The microeconometric estimation of treatment effects—An overview

Summary The need to evaluate the performance of active labour market policies is not questioned any longer. Even though OECD countries spend significant shares of national resources on these measures, unemployment rates remain high or even increase. We focus on microeconometric evaluation which has to solve the fundamental evaluation problem and overcome the possible occurrence of selection bias. When using non-experimental data, different evaluation approaches can be thought of. The aim of this paper is to review the most relevant estimators, discuss their identifying assumptions and their (dis-)advantages. Thereby we will present estimators based on some form of exogeneity (selection on observables) as well as estimators where selection might also occur on unobservable characteristics. Since the possible occurrence of effect heterogeneity has become a major topic in evaluation research in recent years, we will also assess the ability of each estimator to deal with it. Additionally, we will also discuss some recent extensions of the static evaluation framework to allow for dynamic treatment evaluation. The authors thank Stephan L.
