Evaluating the effectiveness of the Spanish police force through data envelopment analysis 总被引:1,自引:0,他引:1
Isabel-María García-Sánchez 《European Journal of Law and Economics》2007,23(1):43-57
The aim of this paper is to evaluate the level of effectiveness of the National Police Force in Spain, attempting to show
the possibilities that the Data Envelopment Analysis technique offers in this field. Furthermore, we have implemented a two-stage
procedure which uses econometric methods to estimate the set of variables which will explain the performance of effective
units. The results of our analysis show that there is a high level of investigative effectiveness, which decreases regarding
coercive and overall effectiveness. This indicates that although there is logic in the cases solved and the culprits arrested,
this cannot be extended, given the level of offences, to the number of cases solved, and to a lesser degree to those arrested
for them. The units which are most effective overall are characterized by the solving of crimes against the right to sexual
freedom and indemnity and by the arrest of a high percentage of those guilty of other offences.

This article builds a simple theoretical model for the optimal expected length of a franchise contract. The main outcome is
that fixed specific investment positively impacts contract duration confirming previous theoretical conjectures. Additionally,
other variables such us the price–cost margin of the franchise, the brand name or the discount factor also play a relevant
role. The empirical analysis using a large sample of franchises operating in Spain confirms the main conclusions of the model.
However, the connection found between investment and duration, although statistically robust, is weak from an economic point
of view. This result suggests the possibility that, in general, most franchisees are not in equilibrium because of the high
standardization of this contract term across franchises. In these cases, the expectation of renewal is likely to be a crucial
element of adjustment. 相似文献

An improved version of the famous Molotov cocktail is the Chemical Ignition Molotov Cocktail (CIMC). This incendiary device contains chemical reagents that enable its self-ignition. The analysis of anions from CIMC residues by capillary electrophoresis (CE) allows the identification of the reagents used to produce the device, and provides forensic analysts with valuable information. Although, sulfate, chlorate, chloride, and perchlorate anions have been recently proposed in the literature as target anions to determine the CIMC composition, the identification of some of them could be controversial due to their presence in the environment. Therefore, the purpose of this study was to identify highly reliable anions capable of indicating the components used to prepare these self-initiated devices. The relationship among the detected anions in CIMC residues and the reagents employed in their elaboration is discussed. Some anions have been proposed as anionic markers of CIMC as incendiary devices. Additionally, the viability of different CIMC compositions was studied. 相似文献

Throughout more than fifty years, the Cuban Revolution has been unable to implement an Economic Management System (ems) to face and overcome the traditional problems of centrally planned economies. When Cuban leaders tried to back away from the planning methods adopted in socialist countries, the economic management suffered from “voluntarism”, with invariably negative consequences. This article proposes a categorization of the economic cycle into upward phases –in which rational economic planning and organization predominate– and downward phases with a highly centralized direction of the economy. A historic-economic analysis of each phase of the cycle is presented, revealing that upward phases were characterized by good or acceptable economic outcomes, while these were poor during downward phases with a prevalence of voluntarism, unless external factors appeared. 相似文献

A rapid and highly species-specific real-time polymerase chain reaction (PCR) assay has been developed for the detection of capercaillie DNA (Tetrao urogallus) in meat and meat mixtures. The method combines the use of capercaillie-specific primers, that amplify a 142bp fragment of the mitochondrial 12S rRNA gene, and a positive control primer pair that amplifies a 141bp fragment of the nuclear 18S rRNA gene from eukaryotic DNA. SYBR(?) Green dye or TaqMan(?) fluorogenic probes were used to monitor the amplification of the target genes. Results obtained with the use of TaqMan(?) probes as detection platform increased the specificity of the real-time PCR assay in comparison with the results obtained using SYBR(?) Green. The proposed real-time PCR assay represents a rapid and straightforward method for the accurate identification of capercaillie that could be used by law enforcement agencies as a tool for the control of poaching and illegal trade of meat from this protected species. 相似文献

The effects of calcination (400–1200°C) on pig bones have been studied using powder X‐ray diffraction (XRD) and secondary modifications, such as color change and weight loss. The characterisation by powder XRD confirmed the presence of the crystalline phase of hydroxyapatite, and comparison of the results obtained at different temperatures suggested that at 650°C, all the organic components and carbonate substitutions were completely removed. Accordingly, these samples were white. In addition, the crystallinity degree and the crystallite size progressively increased with the calcination temperature until 650°C, remaining stable until 1200°C. Below 650°C, bone samples presented organic compounds, resulting in background noise in the diffractogram and gray or black color. In addition, impurities in the lattice correspond to low crystallite sizes. 相似文献

Over the last few years, Moroccans have been disproportionately involved in jihadist terrorism. Morocco has been increasingly identified as one of the largest producers of terrorists and insurgents in Afghanistan, Iraq, and throughout Europe. This article examines the factors behind the emergence of jihadist terrorism in Morocco, and how this terrorist threat has gone beyond this country's borders. Three factors have contributed to this development: the influence of global jihad on potential Moroccan jihadists; the growing Islamization of the country; and deteriorating socioeconomic conditions. In analyzing these variables, special attention will be paid to the Casablanca terrorist attacks on May 16, 2003, marking the debut of suicide terrorism in Morocco. The article will also examine the principal counterterrorist initiatives Morocco has implemented in response to this threat. 相似文献

Governments’ use of debt as a political instrument has been widely studied from the perspective of partisan and electoral cycles, mainly concerning central government. On the whole, previous studies have attempted to determine the effects of political ideology and the proximity of elections on the opportunistic use of public spending. The current study aims to broaden the scope of attention to the effect of partisan and electoral cycles on debt, by means of a broader consideration of the motives that lead politicians to take on a deficit and that are usually linked to the associated electoral risk. More particularly, we examine whether, during the electoral period, greater confidence in re-election can modify party behaviour concerning the use of public spending, and if so, whether the change is greater or smaller depending on the ruling party’s ideology. The results obtained show that local administrations need to incur debt, although politicians take on more liability than is appropriate to their demographic and economic characteristics, especially in an election year. It was also found that political stability favours a reduction in the public deficit, a pattern that is maintained in electoral periods. This effect was found to be independent of the partisan cycle. 相似文献

Dipterous fly larvae (maggots) are frequently collected from a corpse during a criminal investigation. Previous studies showed that DNA analysis of the gastrointestinal contents of maggots might be used to reveal the identity of a victim. However, this approach has not been used to date in legal investigations, and thus its practical usefulness is unknown. A badly burned body was discovered with its face and neck colonized by fly larvae. Given the condition of the body, identification was not possible. Short tandem repeat (STR) typing was performed using the gastrointestinal contents of maggots collected from the victim and was compared to STR profiles obtained from the alleged father. The probability of paternity was 99.685%. Thus, this comparative DNA test enabled the conclusive identification of the remains. This is the first reported case of analysis of human DNA isolated from the gastrointestinal tract of maggots used to identify a victim in a criminal case. 相似文献
