My Chinese Lauria

正Lauriat:An eight-,nine-,ten-course meal featuring a variety of dishes during special Filipino-Chinese celebrations that last for hours.I have a confession to make.China is not in my list of places to visit.I am not a big fan of Chinese food and I don’t eat anything that looks new to me,especially if it is exotic.In fact,the only tea I drink is iced tea.     

The role of Salvadorean NGOs in post-war reconstruction

The Peace Agreement signed recently between the Government and FMLN guerrillas in El Salvador marks the end of a decade of civil war. As both sides of the conflict and the international donor community begin to add up the financial costs of reconstruction, the human, social and psychological costs are carried mainly by the poor of El Salvador. Social organisations and NGOs who became strategists of survival now face the challenge of transforming their accumulated experience into alternative proposals for the building of a more just society and a prosperous nation. This article explores the practical complexities of transition from war to peace; and from emergency aid to sustainable development based on the participation of communities, social organisations, NGOs, and international agencies; and the challenges of building on their experience.     

Alcohol,illicit drugs and medicinal drugs in fatally injured drivers in Spain between 1991 and 2000

The aim of this study was to assess the presence of alcohol, illicit drugs and medicinal drugs among Spanish drivers involved in fatal road accidents between 1991 and 2000. Samples were obtained for 5745 drivers killed in road accidents from January 1991 to December 2000. Of the samples, 91.7% represented males and 8.3% females; 40.7% were under 30 years of age, 31.9% were under 31-50 years of age, 19.5% were over 51 years of age, and for 7.9% the age was unknown. Between 1991 and 2000, some type of psychoactive substance was detected among 50.1% of those drivers killed in road accidents, this being mainly alcohol (43.8%) and, less frequently, illicit drugs (8.8%) and medicinal drugs (4.7%). In all the cases, in which alcohol was detected, combined use with other substances accounted for only 12.5%, whilst in the case of illicit and medicinal drugs, figures representing combined use with other substances were 75.6% for the former and 65.8% for the latter. For one in every three cases (32.0%), a blood alcohol level over 0.8 g/l was recorded; cocaine (5.2%), opiates (3.2%) and cannabis (2.2%) were the three illicit drugs most frequently detected. Among medicinal drugs, were benzodiazepines (3.4%), anti-depressant drugs (0.6%) and analgesics (0.4%). The results show the frequent presence of psychoactive substances, particularly alcohol, among Spanish motor vehicle users involved in fatal road accidents. It should be pointed out that illicit and medicinal drugs in combination with other substances were a common feature.     

Simultaneous determination of thirteen beta-blockers and one metabolite by gradient high-performance liquid chromatography with photodiode-array UV detection

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 相似文献   

Congressional committees and the political economy of federal outlays

The literature on the organization of the United States Congress has been dominated by “distributive” and “informational” theory. One important source of disagreement between these two theories is their characterization of whether individual legislators can engage in pork-barrel activities. Here we provide evidence which indicates that the pork-barrel is alive and well in the contemporary United States Congress. We focus on whether members of power and constituency committees can direct disproportionate federal expenditures to their districts. Finding strong and systematic evidence of pork-barrel activities by committee members provides empirical support for distributive theories of legislative organization.     

Persistent lipsticks and their lip prints: new hidden evidence at the crime scene

Latent lip print test results produced by permanent lipsticks are presented in this work. This cosmetic product, contrary to conventional lipsticks, does not leave visible prints and can thus be overlooked at the crime scene. As print vehicles the study used ceramics, glass, cotton fabric and paper. Lip prints were left to dwell for different periods and were later developed using aluminum powder, cobalt oxide powder and magnetic powder. The results show that identifiable lip prints can be obtained up to 30 days after being produced.     

The 2000-2001 GEP-ISFG Collaborative Exercise on mtDNA: assessing the cause of unsuccessful mtDNA PCR amplification of hair shaft samples

We report the results of Spanish and Portuguese working group (GEP) of International Society of Forensic Genetics (ISFG) Collaborative Exercise 2001-2002 on mitochondrial DNA (mtDNA) analysis. 64 laboratories from Spain, Portugal and several Latin-American countries participated in this quality control exercise. Five samples were sent to the participating laboratories, four blood stains (M1-M4) and a sample (M5) consisting of two hair shaft fragments. M4 was non-human (Felis catus) in origin; therefore, the capacity of the labs to identify the biological source of this sample was an integral part of the exercise. Some labs detected the non-human origin of M4 by carrying out immuno-diffussion techniques using antihuman serum, whereas others identified the specific animal origin by testing the sample against a set of animal antibodies or by means of the analysis of mtDNA regions (Cyt-b, 12S, and 16S genes). The results of the other three human blood stains (M1-M3) improved in relation to the last Collaborative Exercises but those related to hairs yielded a low rate of success which clearly contrasts with previous results. As a consequence of this, some labs performed additional analysis showing that the origin of this low efficiency was not the presence of inhibitors, but the low quantity of DNA present in these specific hair samples and the degradation.As a general conclusion the results emphasize the need of external proficiency testing as part of the accreditation procedure for the labs performing mtDNA analysis in forensic casework.     

Who Will Be the “Principled‐Principals”? Perceptions of Corruption and Willingness to Engage in Anticorruption Activism

Many anticorruption campaigns aim to encourage citizens to demand better control over corruption. Recent literature suggests that perceived high levels of corruption and government effectiveness in controlling corruption will limit citizens' willingness to actively oppose corruption. Using Transparency International's 2013 Global Corruption Barometer, we test these ideas across a 71‐country sample. We find that perceived government effectiveness tends to encourage anticorruption civic action, while perceptions of corruption being widespread tend to have the opposite impact in non‐OECD countries. Our analyses also suggest that the interaction between these perceptions is important; we find that, especially among those who perceive that the level of corruption is high, when confidence in the government's efforts grows, so does their willingness fight corruption.     

A fatal dichlorvos poisoning: concentrations in biological specimens

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.
