Environmental sanitation and pollution control measures in the Odaw-Korle River catchment,Ghana

This article reports on a study that sought to understand the major factors to consider in changing poor environmental sanitation practices in urban communities in Accra, Ghana. The study focused on three main issues: the drivers of sanitation and pollution control measures in the communities; community members’ perceptions on the influence of poor planning on environmental sanitation and pollution; and how existing local governance arrangements influence environmental sanitation and pollution control. It found that efforts are made at the city, community, and individual levels to control poor environmental practices. In order to control environmental pollution, policy initiatives on sanctions should be coupled with the provision of efficient sanitation facilities and services.     

The 1999 Knesset and prime ministerial elections in Israel

This election note delineates the outcome of the 1999 elections in Israel, in which the Prime Minister was directly elected — for only the second time — concurrently with the parliamentary election. It then analyzes the election results produced by Israel's unique electoral system, and assesses their immediate ramifications.     

The Financial Crisis of the Local Authorities in Israel: A Resource-Based Analysis

The financial crisis affecting many of the local authorities in Israel has a significant influence on their ability to supply municipal services of an appropriate amount and quality. So far, studies have been addressed to the financial crisis from a political approach by discussing aspects such as the problematic interrelation between central and local governments together with resource allocation. In this paper we investigate the financial crisis of many local authorities in Israel from a strategic point of view. However, this is by no means to argue that other approaches such as institutional and political ones are not important. Rather, the paper investigates whether the financial crisis affecting many Israeli local authorities is a result of their own strategies and practices.
Specifically, we have used the resource-based approach to explore the nature of their joint crises and the potential strategic responses that the local authorities should adopt in order to move into a more favourable state. In particular, we examine three resource-based systems: customer-oriented, organizational culture, and human resources, as the strategic roots of this crisis. We also examine the way they could produce a sustainable competitive advantage and could lead local authorities from the present position to a better one. The article recommends that the heads of local authorities should move to a resource-based strategy in order to perform both more efficiently and effectively.

The aims of this study were: first, to determine the accuracy of the Cameriere method for assessing chronological age in children based on the relationship between age and measurement of open apices in teeth and, second, to compare the accuracy of this method with the widely used Demirjian et al. method and with the method proposed by Willems et al. Orthopantomographs taken from white Italian, Spain and Croatian children (401 girls, 355 boys) aged between 5 and 15 years were analysed following the Cameriere, Demirjian and Willems methods. The difference between chronological and dental age was calculated for each individual and each method (residual). The accuracy of each method was assessed using the mean of the absolute values of the residuals (mean prediction error). Results showed that the Cameriere method slightly underestimated the real age of children. The median of the residuals was 0.081 years (interquartile range, IQR=0.668 years) for girls and 0.036 years for boys (interquartile range, IQR=0.732 years). The Willems method showed an overestimation of the real age of boys, with a median residual error of -0.247 years and an underestimation of the real age of girls (median residual error=0.073 years). Lastly, the Demirjian method overestimated the real age of both boys and girls, with a median residual error of -0.750 years for girls and -0.611 years for boys. The Cameriere method yielded a mean prediction error of 0.407 years for girls and 0.380 years for boys. Although the accuracy of this method was better for boys than for girls, the difference between the two mean prediction errors was not statistically significant (p=0.19). The Demirjian method was found to overestimate age for both boys and girls but the mean prediction error for girls was significantly greater than that for boys (p=0.024), and was significantly less accurate than the Cameriere method (p<0.001). The Willems method was better than that of Demirjian (p=0.0032), but was significantly less accurate than that of Cameriere (p<0.001).

Decoding hidden darknet networks: What we learned about the illicit fentanyl trade on AlphaBay

The opioid epidemic, impacted from the proliferation of fentanyl, has added impetus to the need to detect fentanyl, sources of fentanyl, and places where fentanyl and drugs adulterated with fentanyl are available. Many darknet marketplaces (DNMs) have rules that ban fentanyl. However, it is unclear how these affect the fentanyl market. Using the AlphaBay DNM as a case study, we conducted mixed methods qualitative research. We scraped and analyzed data from the AlphaBay I2P website using, among other methods, content and social network analysis, to uncover hidden fentanyl networks. Our research highlights the next evolution of darknet marketplaces – the migration of DNMs from Tor to I2P and the methods that can be used identify fentanyl networks, irrespective of where sites are: I2P, Tor, or multihomed on I2P and Tor. Despite its ban in the Global AlphaBay Rules, our research revealed the sale of fentanyl on the AlphaBay DNM. Unlike previous studies, our findings predominantly revealed the covert sale of fentanyl on AlphaBay and predatory vendors selling illicit drugs, which unbeknownst to buyers, contained fentanyl. To a lesser extent, our findings identified the overt sale of fentanyl patches on AlphaBay. Although we examined only one DNM, the prevalence of the covert sale of fentanyl and the presence of predatory vendors underscores the importance of research that decodes the language of vendors who surreptitiously sell fentanyl or drugs adulterated with fentanyl or other illicit substances. The results of our research can inform strategies aimed at disrupting and dismantling DNM fentanyl networks.
