Scientific Research on the Efficiency of Public Expenditures: How and Where is it Going?

ABSTRACT

Recent scientific research has advanced the measurement of the relative performance of organizations and the efficiency of public spending, based on analyzes of the services offered and results achieved. However, from the methodological point of view, there are several methods to analyze the performance and efficiency of spending in the private and public sectors. In this sense, the present study performs a systematic bibliometric review to analyze all scientific publications on the efficiency of public spending published in the last 20 years. The results show that most cost-efficiency analyzes have been limited to education and health expenditures and have used quantitative analysis, mainly through the application of data-involution analysis. The present review is a first step in mapping scientific publications on efficiency in public spending, which will support researchers and managers to make public spending more efficient.     

Undoing a co-operative bargain: The origins and dissolution of federal accommodation of provincial credit unions

The failure of several U.S. regional banks early in 2023 underlined Canada's reputation as home to a resilient banking sector where federal policymakers guard their jurisdictional responsibility over banking against populist impulses and trade off competition for financial stability. This article argues that conventional explanations for this observed stability are incomplete because they omit any discussion of federal policies that shaped the growth of a $550 billion provincially based credit union system. This article reconciles the resulting puzzle by showing how policymakers accommodated credit unions and used them to channel populist impulses but within the bounds of over-arching financial stability concerns.     

Political Ideology and Social Services Contracting: Evidence from a Regression Discontinuity Design

Theoretical perspectives on the ideological influences on government contracting predict that local governments controlled by right-wing political parties will contract out a higher proportion of services than those controlled by left-wing parties. However, empirical evidence on the impact of political ideology on contracting out remains inconclusive. To cast new light on this important issue, the authors apply a quasi-experimental research design to contracting choices in children's social services in English local government. Because local governments in England are largely divided along partisan lines, it is possible to estimate ideological effects using a regression discontinuity design that captures changes in political control at 50 percent of the seats gained in local elections. The regression discontinuity estimates reveal that left-wing controlled local governments exhibit a marked aversion to private sector involvement in service provision and a clear preference for in-house service provision. These results are robust to a variety of alternative specifications.     

The role of alcohol and victim sexual interest in Spanish students' perceptions of sexual assault

Two studies investigated the effects of information related to rape myths on Spanish college students' perceptions of sexual assault. In Study 1, 92 participants read a vignette about a nonconsensual sexual encounter and rated whether it was a sexual assault and how much the woman was to blame. In the scenario, the man either used physical force or offered alcohol to the woman to overcome her resistance. Rape myth acceptance (RMA) was measured as an individual difference variable. Participants were more convinced that the incident was a sexual assault and blamed the woman less when the man had used force rather than offering her alcohol. In Study 2, 164 college students read a scenario in which the woman rejected a man's sexual advances after having either accepted or turned down his offer of alcohol. In addition, the woman was either portrayed as being sexually attracted to him or there was no mention of her sexual interest. Participants' RMA was again included. High RMA participants blamed the victim more than low RMA participants and were less certain that the incident was a sexual assault, especially when the victim had accepted alcohol and was described as being sexually attracted to the man. The findings are discussed in terms of their implications for the prevention and legal prosecution of sexual assault.     

Past victimizations and dating violence perpetration in adolescence: the mediating role of emotional distress and hostility

This study aimed to understand the nature of the relationships between three forms of past victimizations (exposure to interparental violence in childhood, sexual harassment by peers since beginning high school, prior experience of dating violence), physical dating violence perpetration by adolescents, and anger-hostility and emotional distress. The sample was composed of 1,259 high school students aged between 14 and 19 years who answered self-report questionnaires. Mediation analyses were conducted according to Baron and Kenny's approach. Logistic and linear regression analyses reveal that being victim of sexual harassment by peers and of dating violence are associated to physical dating violence perpetration via a partial mediating effect of hostility in girls. Contrary to results with girls, there is a complete mediating effect of emotional distress for boys. Results suggest that dating violence prevention and intervention strategies could be adapted according to gender and that sexual harassment should be addressed.     

Mineralization of mandibular third molars can estimate chronological age--Brazilian indices

Forensic age estimation is an important element of anthropological research, as it produces one of the primary sources of data that researchers use to establish the identity of a person living or the identity of unknown bodily remains. The aim of this study was to determine if the chronology of third molar mineralization could be an accurate indicator of estimated age in a sample Brazilian population. If so, mineralization could determine the probability of an individual being 18 years or older. The study evaluated 407 panoramic radiographs of males and females from the past 5 years in order to assess the mineralization status of the mandibular third molars. The evaluation was carried out using an adaptation of Demirjian's system. The results indicated a strong correlation between chronological age and the mineralization of the mandibular third molars. The results indicated that modern Brazilian generation tends to demonstrate an earlier mandibular third molar mineralization than older Brazilian generation and people of other nationalities. Males reached developmental stages slightly earlier than females, but statistically significant differences between the sex were not found. The probability that an individual with third molar mineralization stage H had reached an age of 18 years or older was 96.8-98.6% for males and females, respectively.     

An assessment of early mandibular growth

Quantification of skeletal data has been shown to be an effective and reliable method of demonstrating variation in human growth as well as for monitoring and interpreting growth. In South Africa as well as internationally, few researchers have assessed mandibular growth in late fetal period and early childhood and therefore standards for growth and age determination in these groups are limited. The purpose of this study was to evaluate growth in the mandible from the period of 31 gestational weeks to 36 months postnatal. A total of 74 mandibles were used. Dried mandibles were sourced from the Raymond A. Dart Collection (University of Witwatersrand), and cadaveric remains were obtained from the Universities of Pretoria and the Witwatersrand. The sample was divided into four groups; 31-40 gestational weeks (group 1), 0-11 months (group 2), 12-24 months (group 3), and 25-36 months (group 4). Twenty-one osteological landmarks were digitized using a MicroScribe G2. Ten standard measurements were created and included: the maximum length of mandible, mandibular body length and width, mandibular notch width and depth, mental foramen to inferior border of mandible, mandibular basilar widths bigonial and biantegonial, bigonial width of mental foramen and mental angle. Data were analyzed using PAST statistical software and Morphologika2 v2.5. Statistically significant differences were noted in the linear measurements for all group comparisons except between groups 3 and 4. The mandible morphologically changed from a round, smooth contour anteriorly to adopt a more sharp and narrow adult shape. A progressive increase in the depth and definition of the mandibular arch was also noted. In conclusion, the mandible initially grows to accommodate the developing tongue (up to 11 months), progressive dental eruption and mastication from 12 to 36 months. Mastication is associated with muscle mass development; this would necessitate an increase in the dimensions of the mandibular notch and associated muscle attachment sites. These findings might be valuable in the estimation of age in unidentified individuals and to monitor prenatal growth of the mandible for the early diagnosis of conditions associated with stunted mandibular growth.
