What explains the continuation of strong executive power despite the introduction of new formal constraints on presidents? This article focuses on the elites working within the state agencies that execute presidential power, who benefit materially from their authority and have incentives to defy formal constraints placed on their own power. To evaluate this claim, I examine Kenya's 2010 constitution, which intended to reduce the power of Kenya's “imperial presidency” through formal constraints on the executive. As implementation has progressed, however, the executive bureaucracy – the Provincial Administration (PA) – has not changed in size, structure, or function, contrary to the explicit goals of the constitution's drafters. Using original interview and archival evidence, I find that the persistence of this agency – and by extension strong executive power – is due to PA administrators’ attempts to protect their material interests. This article shows that formal rule change may be insufficient to spur democratization in the face of entrenched authoritarian bureaucracies with strong incentives to maintain their pre-existing interests.  相似文献

Automatic facial age progression (AFAP) has been an active area of research in recent years. This is due to its numerous applications which include searching for missing. This study presents a new method of AFAP. Here, we use an active appearance model (AAM) to extract facial features from available images. An aging function is then modelled using sparse partial least squares regression (sPLS). Thereafter, the aging function is used to render new faces at different ages. To test the accuracy of our algorithm, extensive evaluation is conducted using a database of 500 face images with known ages. Furthermore, the algorithm is used to progress Ben Needham's facial image that was taken when he was 21 months old to the ages of 6, 14, and 22 years. The algorithm presented in this study could potentially be used to enhance the search for missing people worldwide.  相似文献

The aim of this article is to scrutinise the uncertainty of the Iranian Electronic Commerce Law (IRI ECL 2004) provisions especially on the issue of capacity of parties. Issues of parties’ legal capacity have been resolved in traditional contracts but they are still debatable in electronic commerce transactions. Under UK law, contracts formed by minors for things other than necessities are unenforceable against the minor but enforceable against the merchant (seller) while according to US uniform commercial code in online contracts capacity is not recognized as a legal excuse to nullify a contract. At the mean time, contracts made by incapacitate person is considered null under Iranian law. In spite of technical developments such as digital signatures and smart cards used in verifying the identity and capacity of parties in electronic commerce transactions, the legal certainty on capacity of parties is still questionable. The article also examines the application of traditional contract general rules on parties’ legal capacity in Iran to electronic commerce with reference to EU law. The EU law which is already at an advance stage serves a guide for future development of e-commerce law in Iran.  相似文献

Many organophosphate pesticides (OPs) such as dimethoate are used to eradicate household pests, and those occurring in agriculture and forestry sectors. Combinations of two or more different insecticides have been manufactured to increase their effectiveness. A case of death is presented as suspected organophosphates intoxication. Autopsy was unremarkable except for grayish fluid in the stomach, with garlicky odor. A systematic toxicological analysis on post-mortem specimens revealed high concentrations of dimethoate in blood 38 microg/mL, urine 0.47 microg/mL, brain 2.2 microg/g, myocardial muscle 7.6 microg/g, liver 4.6 microg/g, lung 7.6 microg/g, skeletal muscle 21 microg/g, kidney 55 microg/g and gall bladder 31 microg/g. Blood alcohol was 2.85 g/L, cyclohexanone and cyclohexanol were also detected in the blood but not quantified. The cause of death was determined as organophosphate intoxication.  相似文献

This paper examines the structure and modus operandi of South Asian criminal organisations operating in the UK. It is based on empirical research conducted between 2005 and 2006 among prisoners sentenced for drug offences, a number of drug distributors operating in the market, and observers with a knowledge of the drugs business working for the police force or for rehabilitation services. First, the paper offers an overview of the debate on organised crime, and after a methodological note, the research findings are utilised to propose a typology. Hypotheses are formulated around the illicit drug enterprises involved in British markets. Finally, the implications for law enforcement with respect to these enterprises are discussed.

The aim of this study was to assess mothers’ attitudes toward Corporal Punishment (CP) of children in Iran. A qualitative study was carried out using focus group discussions. Five sessions were held among 42 participants (30 mothers and 12 caregivers). Results indicated that 80% of participants used CP to bring up their children; 70 % did not know the meaning, predisposing factors, and manifestations of child abuse, and more than 50 % did not know the complications resulting from CP and the ways of preventing. Their attitude toward CP was that the use of CP was sometimes necessary to bring up their children while their information about predisposing factors and complications of child abuse might be minimal. The findings have been used in providing an educational package with the topics of parenting skills in order to decrease child abuse that has been resulted by parents.  相似文献

This paper provides a summary of our report for the National Academy of Sciences, Engineering, and Medicine on proactive policing. We find that there is sufficient scientific evidence to support the adoption of many proactive policing practices if the primary goal is to reduce crime, though the evidence base generally does not provide long-term or jurisdictional estimates. In turn, we conclude that crime prevention outcomes can often be obtained without producing negative community reactions. However, the most effective proactive policing strategies do not appear to have strong positive impacts on citizen perceptions of the police. At the same time, some community-based strategies have begun to show evidence of improving the relations between the police and public. We conclude that there are likely to be large racial disparities in the volume and nature of police–citizen encounters when police target high-risk people or high-risk places, as is common in many proactive policing programs. We could not conclude whether such disparities are due to statistical prediction, racial animus, implicit bias, or other causes.
