This paper examines the effect of instrumental and expressive concerns on public confidence in the police in three different residential areas in Sekondi-Takoradi, Ghana’s third largest city. The study was important because of the knowledge vacuum that existed in regard to the empirical validity of the instrumental and expressive theoretical framework within the Ghanaian context. Data for the study was drawn from a baseline survey conducted in three residential areas in the Sekondi-Takoradi metropolis. The findings revealed that instrumental factors played a more significant role in influencing confidence in the police in the Sekondi-Takoradi metropolis compared to expressive factors. More importantly, instrumental factors played a more significant role in influencing confidence in the police at Anaji compared to the other two residential areas used in the study. The paper recommends that there should be more investment in police infrastructure and services to enhance police effectiveness and efficiency. Additionally, the authors also suggest that interventions aimed at improving security at the community level should be guided by periodic safety audits since this will provide a better understanding of the criminogenic problems within these residential settlements. 相似文献

Routine control of 2055 consecutive genotypes revealed discrepancies between the profiles established with the SGM plus and/or Profiler plus kits on one hand, and the profiles established with the Powerplex16 kit on the other hand. Furthermore, five discrepancies for vWA, three for D8S1179, two for FGA and three for D18S51 loci were found. In 10 cases (loci vWA, FGA, D18S51, D8S1179), the SGM plus and/or Profiler plus profiles showed homozygosity and the Powerplex16 genotype revealed heterozygosities which were confirmed to be true, both by typing with individual primer pairs and DNA sequencing. In four cases (two discrepancies at locus FGA, one at D18S51 and an abnormal paternity pattern for D5S818), the Powerplex16 kit showed apparent homozygosity and the SGM plus and/or Profiler plus kits showed heterozygosity. Mutation analysis could be performed for some of these individuals and evidenced variants, presumably leading to an annealing failure of one primer; the identified mutations are reported. It is suggested that databases should include information about the kits used to determine the profiles while ensuring that the primer sequences are made available. 相似文献

A new rapid and sensitive high-performance liquid chromatography (HPLC) method has been developed for the simultaneous identification and quantification in human plasma of the 13 most commonly prescribed beta-blockers and one active metabolite-atenolol, sotalol, diacetolol, carteolol, nadolol, pindolol, acebutolol, metoprolol, celiprolol, oxprenolol, labetalol, propranolol, tertatolol and betaxolol. It involves liquid-liquid extraction procedures followed by liquid chromatography coupled to photodiode-array UV detection with a fixed wavelength at 220 nm for quantification. Compounds were separated on a 5 microm Hypurity C(18) (ThermoHypersil) analytical column (250 mm x 4.6 mm, i.d.) using a gradient of acetonitrile-phosphate buffer pH 3.8 at a flow rate of 1.0 ml/min. The total analysis time was 26 min per sample. Extraction recoveries were between 74 and 113% for the polar compounds and between 20 and 56% for the most apolar compounds. Calibration lines were linear in the range from 25 to 1000 ng/ml for all compounds excepted carteolol and nadolol (50-1000 ng/ml), all of them with coefficients of determination (r2 values) >/=0.994. Limits of detection (LODs) ranged from 5 to 10 ng/ml. Intra-assay and inter-assay precision and accuracy were studied at two concentration levels (100 and 500 ng/ml). The intra-assay coefficients of variation (CVs) for all compounds were = 8.3% and all inter-assays CVs were below 12.6%. The intra-assay and inter-assay accuracies for all compounds were found to be within 91.4 and 105.6% at 100 ng/ml and within 94.1 and 107.4% at 500 ng/ml. Thus, the performance of the method described allows its use in toxicological screening and in quantification of the most prescribed beta-blockers drugs. 相似文献

This article looks at the way the Brazilian writer and educator Nísia Floresta addresses issues of race and class within her construction of nationhood. This is achieved through a consideration of the specific subject of maternal breast-feeding as discussed by Floresta in two texts, written in Brazil and France, respectively. A comparison of these works reveals a very different engagement with race and class factors in determining women's claim to citizenship. Floresta, in common with early 19th-century European feminism, believed this claim to lie within the domestic sphere, primarily in the role of mother and educator. The article considers how, as a vital aspect of that role, she portrays maternal breast-feeding as both natural and patriotic. It also highlights the extent to which Floresta was influenced by the prevailing concerns of her contemporaries regarding the risks of wet nursing and the threat posed by household slaves, before going on to consider how this discourse leads Floresta to exclude black slave women from her vision of patriotic motherhood, while acknowledging the maternity of women of all classes in a European context. Patriotic concerns, shaped by racial prejudices, overshadow Floresta's feminism, prohibiting the kind of unifying discourse of motherhood, which she claimed to profess. 相似文献

Qualitative research in politics is predominantly interview-based. Observation is neglected as a research tool by political scientists. This article presents the case for using observation techniques in political research. Drawing from the authors experience of using structured observation to research Chief Executives, the article shows how observation can be included as a valuable part of a qualitative research strategy. It addresses the how, where, when and why of applying observation to political research. The crucial advantage of observation methods is identified as understanding the context and environment in which actions occur and decisions are taken. 相似文献

This paper presents richer contemporaneous evidence of Congress's role in the passage of the Radio Act of 1927, the act which established the basic statutory framework that still governs federal regulation of broadcasting in the United States. Recent analysis finding the court's decision in Tribune Co. v. Oak Leaves Broadcasting Station to have been the cause of Congress's action on the radio bill is shown to rest on an inaccurate chronology of congressional decisionmaking. More closely examining the actions of legislators upon whose votes passage of the radio act depended, this paper contributes new evidence of strategic orchestration surrounding the perceived “chaos of the airwaves” that stimulated broadcasting regulation. Original congressional documents show that, in a political context characterized by costly information, intra-congressional manipulation of information costs was an important factor in the adoption of the Radio Act of 1927. Personal ties between executive branch officials are shown to have spawned a key legal opinion that prompted passage of the radio bill. 相似文献

Soldier,civilian, criminal: identifying pathways to offending of ex-armed forces personnel in prison
Verity Wainwright Sharon McDonnell Charlotte Lennox Jenny Shaw Jane Senior 《心理学、犯罪与法律》2016,22(8):741-757
Little is known about why some ex-armed forces personnel become involved in the criminal justice system, however, they represent the largest known occupational group in prison. In-depth interviews were employed to explore possible pathways to offending. Twenty ex-armed forces personnel in prison were recruited from five prisons in England. Data were analysed using a combination of thematic analysis and constant comparison methods rooted in grounded theory. Four predominant themes were identified: experiences of trauma and adversity; belonging; impulsivity and creating a soldier. Participants had experienced a number of traumatic incidents and adversity in their lives, encompassing pre, during and post-service but felt a sense of belonging in the armed forces. Participants demonstrated impulsivity in a number of areas with links to both their service in the armed forces and offending behaviour. The creation of the identity of ‘soldier’ was perceived to impact participants’ lives in a number of ways, including their offending, alcohol use and coping with trauma. The interplay of these themes and their potential impact on participants’ pathways to offending are discussed. 相似文献

As a result of globalisation and changing technologies, young people are increasingly required to engage with the broader world beyond their local and national communities. This raises significant questions about the ways and spaces in which young people will need to engage as active citizens, and the new tools and resources that young people will need to equip them for their futures. The Global Connections Program has been developed to address these identified needs. It is a youth-led global learning initiative which aims to provide an opportunity for connection and learning among young people in Australia and Indonesia. This article explores Plan's youth-led approach to global learning, with a focus on the implementation and evaluation findings of the Global Connections Program, as well as the challenges faced thus far. 相似文献

Abstract: A 54-year-old man was found dead with a bottle containing a brownish fluid near him. A toxicological screening was carried out in blood, urine, and stomach content. Only dichlorvos (2,2 dichlorovinyl O-O dimethylphosphate or DDVP) was found. A simple and rapid method, using DDVP-D6 as an internal standard, was developed for the determination of DDVP by gas chromatography/mass spectrometry (GC/MS). The method was linear from 1 to 10 mg/L. Intraday and interday precisions were all <15%. DDVP concentration in cardiac blood was approximately four times higher than in peripheral blood. A high concentration was found in the heart showing a cardiac tropism of DDVP, kidney and lung concentrations being much lower. No DDVP was found in liver. DDVP stomach content was 38 g. The amount presumed ingested was 82 g, c . 1000 mg/kg of body. The oral LD50 for DDVP ranges between 20 and 1090 mg/kg in animals but is not known for humans. 相似文献
