Public–Private Partnerships: An International Performance Review

Public–private partnerships are enjoying a global resurgence in popularity, but there is still much confusion around notions of partnership, what can be learned from our history with partnerships, and what is new about the partnership forms that are in vogue today. Looking at one particular family of public–private partnerships, the long-term infrastructure contract, this article argues that evaluations thus far point to contradictory results regarding their effectiveness. Despite their continuing popularity with governments, greater care is needed to strengthen future evaluations and conduct such assessments away from the policy cheerleaders.     

Violations of out-group and in-group regulations in the eyes of ordinary and protected prisoners: an instance of judgmental modularity

According to the functional theory of cognition, everyday life blaming for wrongdoing reflects individuals' functional morality. The judgments of normative people were found to be modular, that is, changeable as a function of the social role taken at the moment of the judgment. This article presents several empirical indications that prisoners' functional moral judgments are modular as well. These studies were conducted within the experimental framework of functional measurement, which was chosen due to its ability to bypass prisoners' suspicion and resistance to out-group investigations. The studies focus on delinquents' core moral issues such as eyewitness testimony and informing to out-group authorities. As expected, the judgments of ordinary and protected inmates were modular. It is claimed that these findings are applicable to offender rehabilitation and correction and to offender therapy.     

The Impact of Competition and Labor Remuneration on Profitability in China's Industrial State-owned Enterprises

China's industrial state-owned enterprises (SOEs) have seen a secular decline in profitability throughout the reform period. Barry Naughton argues that this decline was in large part due to a decline in monopoly rents as competition with enterprises in other ownership forms increased. Fan Gang and Woo Wing-Thye, on the other hand, contend that profitability declined across all sectors independent of the degree of competition, and that excessive labor remuneration accounts for the broad decline in SOE profitability. Testing the two hypotheses with aggregate sectoral and provincial data from the mid-1980s to the late-1990s, neither appears convincing. Yet at closer inspection these are not competing hypotheses. The two causes affect overall profitability through different channels. Competition and labor remuneration have a highly significant impact on intermediate profitability measures that take the two channels into account separately. Together they explain most of the variation in overall profitability.     

Prosthetic restorations, dental root fillings and periodontal bone resorptions as a forensic-odontologic aid for determining the age above 18 years: A radiographic study of orthopantomograms from a group of teenagers and yount adults

The human teeth are a valuable source of information concerning identification and age calculation in forensic sciences. Dental treatment often causes permanent alteration of the teeth, which is visible on radiographs. The correlation of prosthetic restorations, root canal fillings and periodontal bone loss with chronological age has not yet been used for determining the completed 18th year of life in teenagers and young adults, e. g. for legal and anthropological purposes. The aim of this study was to determine whether the evaluation of such findings on radiographs correlates with the chronological age in teenagers and young adults. MATERIAL AND METHODS: The dental X-rays (orthopantomogram, OPG) of 1053 outpatients (age: 14 to 24 years) were avaluated. The values "prosthetically restored", "filled dental root", or "periodontal bone loss" were recorded for each tooth present. The data were then evaluated using statistical tools. RESULTS: The correlation between the number of prosthetically restored teeth and the chronological age is high. The positive predictive value of determining an age of at least 18 years proved to be very high. However, these findings are rarely present in this age group. The number of endodontically treated teeth correlated less exactly with age. On the other hand, the determination of periodontal bone loss gave reasonable positive predictive values for the threshold value "chronological age of 18 years or more". DISCUSSION: This study provides for the first time predictive values for the estimation whether a person is 18 years of age, based on the evaluation of teeth with prosthetic restorations, root canal fillings or periodontal bone loss on OPGs only. Whereas the number of patients with such findings is generally low in this age group, some of the positive findings can be used for age estimation as an adjunct to other sources of age calculation. The sole application of these criteria is not recommended, as sanitary conditions of the teeth depend on both social and individual circumstances. Therefore, the calculated values also reflect the culture of the sample studied. Finally, they are time-dependent and have to be compared to data from other populations. These results have some bearing on the field of forensic odontology.     

Virtopsy: postmortem imaging of the human heart in situ using MSCT and MRI

The rapid further development of computed tomography (CT) and magnetic resonance imaging (MRI) induced the idea to use these techniques for postmortem documentation of forensic findings. Until now, only a few institutes of forensic medicine have acquired experience in postmortem cross-sectional imaging. Protocols, image interpretation and visualization have to be adapted to the postmortem conditions. Especially, postmortem alterations, such as putrefaction and livores, different temperature of the corpse and the loss of the circulation are a challenge for the imaging process and interpretation. Advantages of postmortem imaging are the higher exposure and resolution available in CT when there is no concern for biologic effects of ionizing radiation, and the lack of cardiac motion artifacts during scanning. CT and MRI may become useful tools for postmortem documentation in forensic medicine. In Bern, 80 human corpses underwent postmortem imaging by CT and MRI prior to traditional autopsy until the month of August 2003. Here, we describe the imaging appearance of postmortem alterations--internal livores, putrefaction, postmortem clotting--and distinguish them from the forensic findings of the heart, such as calcification, endocarditis, myocardial infarction, myocardial scarring, injury and other morphological alterations.
