The provision of subsidized child care has grown to become asizeable economic activity in Sweden during recent decades.This paper examines the changed financial relation betweencentral and local governments and the impact of child-caregrants on local government behaviour. We find that during anearlier regime, with a system of matching grants, localgovernments responded strongly to the incentives of the rules.This resulted in both intended and unintended outcomes, aswell as a distortion of information to the central government.Experiences from a recent transition of regime towards a kindof closed block grant system, illustrates new types ofadaptive behaviour but also the problem of finding a formulafor a fair allocation of resources among local governments.When designing a block grant system a distinction must be madebetween expenditures and resource needs; cost expenditure datado not necessarily reflect resource needs in cases where thereare national categorical equity goals related to socialservices of a merit-want character.  相似文献

Abstract After a discussion of possible components in a definition of 'cumulation' and the relative lack of cumulation in political science, a scheme for research strategies is outlined with the aim of facilitating cumulation, or at least facilitating a diagnosis of the state of political science in this respect. The scheme includes three types of studies: (1) analysis of the formal properties of theoretical approaches in political science, (2) content analyses in the form of inventories of problems, propositions and concepts in the discipline, (3) evaluational analysis, i.e. an assessment of what 'theory criteria' to use for evaluating the approaches and of the probable relations between these criteria.  相似文献

An intoxication following administration of morphine, tramadol and atracurium in a suicide case is reported. The route of administration and the amount of the particular drug were known from the investigation of the death scene and the findings of the postmortem examination. Tramadol was present in the gastric contents as well as in blood, liver, kidney and brain samples, whereas the drug could not be detected in muscle. All body fluids and tissues investigated contained morphine as well as its 3- and 6-glucuronides with the exception of muscle tissue. The concentrations of morphine and its glucuronide metabolites were determined by LC/MS following solid phase extraction. Interestingly, the concentration of M6G in brain, liver and kidney were close to the concentration of M3G in the particular tissue. This phenomenon might be explained by a preferential hydrolysis of M3G or by a preferential formation of M6G postmortem. Measurement of morphine and M6G in femoral blood and cerebrospinal fluid may be a useful indicator in rapid deaths.  相似文献

3,4-methylenedioxyamphetamine (MDA) derivatives are increasingly abused central nervous system stimulants with neurotoxic properties. In recent years a number of controlled substance analogs (designer drugs) with high structural variety reached the illegal market making their identification an arduous task. The underivatized compounds give very similar or even virtually identical electron impact mass spectra containing mainly intense C(n)H(2n+2)N(+) immonium ions. Using tandem mass spectrometry (MS-MS) the additional structural information contained in the collision induced dissoziation (CID) mass spectra of molecular ions using electron impact (EI) and especially chemical ionization (CI) allowed an unequivocal differentiation of 18 studied regioisomeric 1-(methylenedioxyphenyl)-2-propanamines and 1-(methylenedioxyphenyl)-2-butanamines.Further synthetic methods are presented for 1-(3,4-methylenedioxyphenyl)-N-propyl-2-butanamine, N-isopropyl-1-(3,4-methylenedioxyphenyl)-2-butanamine and four 1-(2, 3-methylenedioxyphenyl)-2-butanamines. N-alkylated 1-(3, 4-methylenedioxyphenyl)-2-butanamine compounds (e.g. MBDB) are also known to be abused psychoactive agents (entactogenes) without the sympatomimetic effects of the 3,4-methylenedioxyamphetamines.  相似文献

ABSTRACT

The Turkish Armed Forces (TAF) have been the main discussion topic in the political arena over the last decade in Turkey, with a focus on curtailing military supervision over political life. This article investigates the evolution of civil–military relations (CMR) in Turkey. Thus, the aim of this study is to explore the factors and dynamics that have led to the development and realignment of CMR in Turkey. The focus will be on how military tutelage in Turkey has been ended, what factors have caused this and finally whether Turkish CMR have been normalized.  相似文献

ABSTRACT

Factories remain significant sites of employment, crucial to capitalism. In the twentieth century, scholars registered achievements in documenting their history, but since the late 1980s, and for a generation, the field lost impetus within labour history although insights continued to accumulate through work in adjacent disciplines. The factory has not featured on the agenda of ‘transnational’ and ‘global’ labour history, but we suggest that it can and should contribute to that broader global project, reinvigorating labour history, not least by contributing a dimension close to workers’ everyday experience.  相似文献

Strength of belief and risk   总被引:4,自引:0,他引:4  
The purpose of this paper is to review work on subjective probability and strength of belief, in particular with reference to situations involving a high degree of risk. Work concerned mostly with cognitive limitations and shortcomings is discussed and some implications for societal responses to risky technology are offered. It is concluded that there is, in the literature on subjective probability, a lack of work on small probabilities and on the emotional influence of belief formation to be expected in situations that are related to large social values.This study was supported by a grant from the Committee for Future Oriented Research, Stockholm, Sweden.  相似文献

We present a case of an accidental autoerotic death involving the inhalation of a propane-butane gas mixture, also known as LPG (liquefied petroleum gas). A 19-year-old male was found dead in supine position in his bed in a residential accommodation one day after he was last seen alive. On a personal computer at the end of the bed, a pornographic movie was still running. On his left shoulder, an empty rubber balloon and on the bedside 2 empty "Kisag-Gas" cartridges were found. Toxicologic investigations revealed an intoxication with propane and butane, together with a recent consumption of cannabis. This case report compares the toxicologic findings with other recently published cases, and the theories of the toxic effects are discussed.  相似文献

This paper describes an effort to develop a clinical tool for the continuous monitoring of risk for violence in forensic mental health clients who have left their institutions and who are dwelling in the community on a conditional release basis. The model is called Structured Outcome Assessment and Community Risk Monitoring (SORM). The SORM consists of 30 dynamic factors and each factor in SORM is assessed in two ways: The current absence, presence or partial och intermittent presence of the factors, which is an actuarial (systematized and 'objective') assessment. Secondly, the risk effect, i.e. whether the presence/absence of factors currently increases, decreases or is perceived as unrelated to violence risk, is a clinical (or impressionistic) assessment. Thus, the factors considered via the SORM can be coded as risk factors or protective factors (or as factors unimportant to risk of violence) depending on circumstances that apply in the individual case. Further, the SORM has a built-in module for gathering idiographical information about risk-affecting contextual factors. The use of the SORM and its potential as a risk monitoring instrument is illustrated via preliminary data and case vignettes from an ongoing multicenter project. In this research project, patients leaving any of the 9 participating forensic hospitals in Sweden is assessed at release on a variety of static background factors, and the SORM is then administered every 30 days for 2 years.  相似文献
