This article examines whether the payoff from engaging in innovation‐generating activities is contingent on an organization's level of customer and learning orientation. The authors suggest that innovative activity is associated with higher public service quality when the level of customer and learning orientation within the focal organization is high. They test this hypothesis by drawing on a novel panel data set covering all public nonspecialist hospital organizations in England. Using dynamic panel data estimation techniques, the authors find strong support for a direct relationship between innovative activity and public service quality and for a moderating role of both customer and learning orientation. These findings call for a contingency perspective on public sector innovation and highlight some of the boundary conditions that need to be in place if public service organizations are to benefit fully from their innovative activities. 相似文献

Through the in‐depth ethnographic study of one squatter neighborhood in Montevideo and its leader's political networks, this article illustrates a successful strategy through which some squatter neighborhoods have fought for their right to the city. This consists of opportunistic, face‐to‐face relationships between squatter leaders and politicians of various factions and parties as intermediaries to get state goods, such as water, building materials, electricity, roads, and ultimately land tenure. Through this mechanism, squatters have seized political opportunities at the national and municipal levels. These opportunities were particularly high between 1989 and 2004, years of great competition for the votes of the urban poor on the periphery of the city, when the national and municipal governments belonged to opposing parties. In terms of theory, the article discusses current literature on clientelism, posing problems that make it difficult to characterize the political networks observed among squatters. 相似文献

Lip prints are thought to have the ability to distinguish individuals and, hence, have a potential use in human identification purposes. However, questions remain regarding their utility for sex determination. This study aimed to classify lip prints for different individuals in a Portuguese population and to determine whether sex differences exist. Lip prints of 25 females and 25 males were obtained using dark-colored lipstick and cellophane tape. Lip prints were analyzed using a magnifying lens and classified according to the Suzuki and Tsuchihashi classification. A Type II pattern was found to be most common. A comparison of lip-print patterns between males and females showed results with a statistically significant difference: Type III pattern was most common in males, and a Type II pattern in females. This study corroborates the hypothesis that lip prints are able to distinguish individuals and may be useful in sex determination. 相似文献

In this paper we seek to contribute to a greater understanding of legal citizenship by exploring the gendered experiences of Latin‐American‐origin immigrants in the greater Phoenix metropolitan area as they go through the legalization process. To explore this gendered angle we rely on in‐depth interviews conducted from 1998 through 2008 with women and men from Guatemala, El Salvador, Honduras, and Mexico. The data reveal that although immigration policies and procedures are presumably gender neutral, they are in fact inflected with gendered meanings and enacted in gendered social structures. Gender ideologies permeate the processes to differentially affect the legalization, permanent legal residence, and citizenship processes of immigrant women and men. This article points to key gender inequalities in immigration law. 相似文献

The dissemination of public sector information is not carried out exclusively by public administration. A significant proportion of public sector information constitutes the raw material used by the content industry to offer goods and services and by citizens to provide richer information. In the European Union, Directive 2003/98/EC on the reuse of public sector information establishes a set of rules governing the reuse of public sector information. Although this rule is not intended to provide greater transparency, the re‐use of public sector information could have this effect. This article sets out the European policy on public sector information reuse and it looks in depth at the content of Spanish Act 37/2007, of 16 November, about the reuse of public sector information, as a case study, outlining some of the instruments that have been used in Spain as well as in other Member States to promote the reuse of public sector information. 相似文献

Vertebral artery removing constitutes a significant forensic pathology challenge. Dissection techniques during head-neck autopsy are based on anterior approach, a difficult method, which is unable to assess the transverse part of the artery. This work presents an original and simple method for dissecting vertebral arteries by a posterior approach, opening the vertebroarterial canal through the spinal canal without any special equipment. Once the spinal cord is removed, the transversarium foramens are opened by an internal cut at the pedicle and an external cut at the transverse process. This enables us to visualize vertebral arteries in its entirety. The method improves both the examination of the upper extracranial segment of the vertebral artery and the neuropathological study when arterial injury is suspected. Applying this method routinely is both feasible and useful in suspected cases of vertebral artery trauma and could contribute to assess more precisely the actual incidence of this injury. 相似文献

When writing ink is placed on a substrate, a drying process begins. This process is dependent on the composition of the ink and of the substrate. Lociciro et al. provide an equation that describes the drying process based on models developed by earlier investigators. The work given here develops an equation for the drying process that is based on a different and rather simple model. This model considers the evaporation of a solution in an opened vertical container (e.g., a beaker) and consists of a volatile, non-hygroscopic solvent with a non-volatile solute dissolved in it. Three assumptions are made: (a) the rate of evaporation is proportional to the vapor pressure of the solution and to the solution's exposed surface area, (b) this solution vapor pressure is proportional to the solvent vapor pressure with the proportionality constant being the solvent mole fraction (Raoult's law), and (c) a small fraction of the solvent remains trapped in the solute after evaporation ceases. What results is a differential equation, which, when solved, gives the solvent weight W(t) as an implicit function. What emerges naturally from this treatment is the fact that the function W(t) can have a point of maximum acceleration. Prior to this point the drying process is fast and after this point, the drying process is slow. An approximation to W(t) is taken to be the sum of two exponential functions, one describing the fast drying region and the second describing the subsequent slow drying region. Upon including an additive constant, this approximation turns out to be similar to, but not the same as that provided by Lociciro et al. However, their equivalence is shown and then tested using the two inks examined by Lociciro et al. (the drying of a Bic and a Staedtler blue ballpoint ink). The examples of (solvent+solute) systems ("inks") given here consist of the solvent (2-phenoxyethanol) and a solute such as a dye (crystal violet) or a polymer resin such as synthetic resin SK or polyvinyl butyral. In the case of polymers, the Raoult's law assumption is replaced with one developed by the Flory-Huggins theory of solutions. Saturation and film formation, both of which slow the evaporation rate, are also discussed. 相似文献

Traumatic vertebral artery dissection is not often seen by forensic pathologists, and cases investigated are scarce in the forensic literature. We present the case of a 40-year-old woman cyclist who was struck by a car while wearing a helmet, and was neurologically near normal immediately thereafter at Emergency. She presented 48 h later with acute right hemiparesis, decreasing level of consciousness, and unsteadiness. CT revealed massive cerebellar infarction. CT angiography was normal. The patient died in coma 7 days after injury and autopsy revealed bilateral edematous cerebellar infarction and bilateral vertebral artery dissection. Rotational neck injury and mural tear in the wall of the Atlantic parts of both vertebral arteries is suggested as the possible mechanism of the arterial injury. Head and neck injuries are reported as a precipitating cause of vertebral artery injury. The possible influence of trauma may be further underestimated if longer intervals between vessel dissection and ischemia occur. The current case illustrates that "talk-and-die" syndrome may be due to occult vertebral artery dissection, possibly bilateral. In forensic cases of delayed death after mild trauma to the head and neck, the vertebral arteries should be examined for the cause of death. 相似文献

The investigation of uncertain fatalities requires accurate determination of the cause of death, with assessment of all factors that may have contributed to it. Gasoline is a complex and highly variable mixture of aliphatic and aromatic hydrocarbons that can lead to cardiac arrhythmias due to sensitization of the myocardium to catecholamines or acts as a simple asphyxiant if the vapors displace sufficient oxygen from the breathing atmosphere. This work describes a sudden occupational fatality involving gasoline. The importance of this petroleum distillate detection and its quantitative toxicological significance is discussed using a validated analytical method. A 51 year-old Caucasian healthy man without significant medical history was supervising the repairs of the telephone lines in a manhole near to a gas station. He died suddenly after inhaling gasoline vapors from an accidental leak. Extensive blistering and peeling of skin were observed on the skin of the face, neck, anterior chest, upper and lower extremities, and back. The internal examination showed a strong odor of gasoline, specially detected in the respiratory tract. The toxicological screening and quantitation of gasoline was performed by means of gas chromatography with flame ionization detector and confirmation was performed using gas chromatography-mass spectrometry. Disposition of gasoline in different tissues was as follows: heart blood, 35.7 mg/L; urine, not detected; vitreous humor, 1.9 mg/L; liver, 194.7 mg/kg; lung, 147.6 mg/kg; and gastric content, 116,6 mg/L (2.7 mg total). Based upon the toxicological data along with the autopsy findings, the cause of death was determined to be gasoline poisoning and the manner of death was accidental. We would like to alert on the importance of testing for gasoline, and in general for volatile hydrocarbons, in work-related sudden deaths involving inhalation of hydrocarbon vapors and/or exhaust fumes. 相似文献
