Credit and business cycles’ relationship : evidence from Spain

This study provides evidence on the interaction between business and credit cycles in Spain during the period 1970–2014. The paper works on three analyses: the cycle turning points are identified; the main features of credit and business cycles are documented; and in both cycles the causal relationship is assessed. We find differences in the features of the business and credit cycle phases, which lead to a scant degree of synchronization over time. The lack of synchronization might be a sign that the cyclic interaction could be non-contemporaneous. Our results reveal that there is causation. A significant lagged rela- tionship between business and credit cycles is found; specifically, fluctuations of the business cycle lead fluctuations of the credit to non-financial corporations and a lag exists with respect to the fluctuations of the credit to households. We also examine episodes of credit boom and credit crunch. In the period 1970–2014, Spanish credit booms did not involve deeper business cycle contractions and credit crunches were not associated with deeper and longer business cycle contractions. These differences are related with the great importance of the real estate sector in Spain.info:eu-repo/semantics/publishedVersio

Intensive group behavioral treatment (IGBT) for children with selective mutism: A preliminary randomized clinical trial.

OBJECTIVE: Very few controlled trials have evaluated targeted treatment methods for childhood selective mutism (SM); the availability of evidence-based services remains limited. This study is the first controlled trial to evaluate an intensive group behavioral treatment (IGBT) for children with SM. METHOD: Twenty-nine children with SM (5-9 years; 76% female; 35% ethnic minority) were randomized to immediate SM 5-day IGBT or to a 4-week waitlist with psychoeducational resources (WLP), and were assessed at Week 4 and again 8 weeks into the following school year. RESULTS: IGBT was associated with high satisfaction and low perceived barriers to treatment participation. At Week 4, 50% of the immediate IGBT condition and 0% of the WLP condition were classified as "clinical responders." Further, Time × Condition interactions were significant for social anxiety severity, verbal behavior in social situations, and global functioning (but not for SM severity, verbal behavior in home settings, or overall anxiety). School-year follow-up assessments revealed significant improvements across all outcomes. Eight weeks into the following school year, 46% of IGBT-treated children were free of an SM diagnosis. In addition, teachers in the post-IGBT school year rated less school impairment and more classroom verbal behavior relative to teachers in the pre-IGBT school year. CONCLUSIONS: Findings provide the first empirical support for the efficacy and acceptability of IGBT for SM. Further study is needed to examine mechanisms of IGBT response, and other effective SM treatment methods, in order to clarify which treatment formats work best for which affected children.

Dynamic Integrity Constraints Definition and Enforcement in Databases: A Classification Framework

A dynamic constraint expresses conditions that involve facts of two or more states of the database. Since the database is expected to satisfy such conditions, a fundamental issue about integrity constraints is their enforcement. Many methods have been developed in this respect. The purpose of this paper is to present a brief survey of methods for dynamic constraint definition and enforcement. Also we classify and compare these methods with respect to several relevant features.
