论谭恩美小说中的母亲形象及母女关系的文化内涵

美国华裔作家谭恩美在小说中选择中国母亲和女儿的故事作为创作题材并成功地塑了中国母亲形象,在很大程度上是她作为华裔作家的中国情结和中国化意识使然。在其小说中,母亲是中国化传统的载体,是历史与记忆的中介,是连接过去与现在的桥梁。中国化传统通过母亲得以延伸,历史和记忆通过母亲得以重建。谭恩美的小说之所以在主题和艺术上具有特的魅力,一个重要的原因就在于其小说中母亲形象的感染力以及母女关系所折射出的深邃的化内涵。     

Q&A in legislative oversight: A framework for analysis

Parliamentary questions are an essential tool of legislative oversight. However, the extent to which they are effective in controlling the executive remains underspecified both theoretically and methodologically. This article advances a systematic framework for evaluating the effectiveness of parliamentary questions drawing on principal–agent theory, the public administration literature on accountability and communication research. The framework is called the ‘Q&A approach to legislative oversight’ based on the premise that the study of parliamentary questions (Q) needs to be linked to their respective answers (A) and examined together (Q&A) at the micro-level as an exchange of claims between legislative and executive actors. Methodologically, the Q&A approach to legislative oversight offers a step-by-step guide for qualitative content analysis of Q&A that can be applied to different legislative oversight contexts at different levels of governance. It is argued that the effectiveness of Q&A depends on the strength of the questions asked and the responsiveness of answers provided, which are correspondingly operationalised. To illustrate the merits of the approach, the article includes a systematic case study on the relationship between the European Parliament and the European Central Bank in banking supervision (2013–2018), showing the connection between specific institutional settings and the effectiveness of parliamentary questions.     

Iran’s Latin America Strategy: 2005 to Present

Iran has expanded its trade relations with Latin America since 2005. Many argue that the reasons for such activities are for financial gain and to bypass the sanctions. This article argues that economic gain are miniscule and that the primary objectives of Iran are two-fold: first, to assist its nuclear program; and second, to develop deterrence against the U.S. possible military option against Iran.     

Semi quantitative detection of signature peptides in body fluids by liquid chromatography tandem mass spectrometry (LC–MS/MS)

This study covers a modified semi-quantitative approach to detecting signature peptides for body fluid identification. A liquid chromatography tandem mass spectrometer normally used for toxicology was adapted to detect target ion transitions for five semen or saliva specific peptides. Peptide concentrations were measured based on a mixture of synthetic peptide standards. Samples were processed using a three-hour trypsin digestion and Microcon membrane filtration. This method generates PCR compatible DNA and peptide fractions that can be typed without any further treatment. Preliminary validation tests covered stains on different substrates, semen/saliva mixtures, limit of detection, and repeatability. All signature peptides were present at different concentrations, varied amongst donors, and were tissue specific. Saliva peptides were detected at lower concentrations and had a higher limit of detection (LOD). Semen peptides had higher concentrations and were detected even as a minor component in a mixture. All semen peptides and all, but one, saliva peptides were detected on the various substrates. Semen peptide concentrations had relative standard deviations (RSDs) lower than 20%, indicating high repeatability, different from saliva where higher RSDs were observed. DNA fractions did not show signs of degradation or PCR inhibition.     

Deepwater or Troubled Water? Principal–Agent Theory and Performance-Based Contracting in the Coast Guard’s Deepwater Modernization Program

In the mid-1990s, the United States Coast Guard began planning a modernization effort known as the Deepwater program to replace an aging inventory of cutters, aircraft, and small boats. This effort involved a consortium of corporations to develop a “system of systems” to meet performance-based requirements and build the new equipment. This article examines the Deepwater program through the lens of multilayered principal–agent theory and evaluates the performance-based contracting (PBC) method used to alleviate strains linked to accountability from the principal–agent relationship. The findings help better understand the dilemmas prescribed from multilayered principal–agent theory and PBC by illustrating the accountability issues faced by smaller organizations when engaging in complex, large-scale procurement.     

Militarizing civilians in Singapore: preparing for ‘Crisis’ within a calibrated nationalism1

The Singaporean polity has created the ‘militarized civilian’. This policy phenomenon beckons the question: How is this cross-fertilization carried out in Singapore's civil–military relations? Militarization is in the first sense meant to inculcate a calibrated dual personality within the civilian whereby being an effective soldier requires indulging in simulated military suffering as a badge of pride; at the same time, the citizen soldier has to believe that military and civilian values are perfectly interchangeable and contribute equally to the maintenance of peace. In a second sense, militarization is equally about permanently ritualizing sacrifices for a communitarian defence. We argue that while mostly successful, militarization also produces the tension arising from the need to appear pugnaciously vigilant while avoiding the casualties that must logically arise from heightened simulated combat. This tension is explained through two dimensions of ongoing crises: the parameters of a politically dramatized National Service ritual; and the constant propaganda of geopolitical dangers threatening the Republic.     

Analysis of the First- and Second-Generation Raving Dragon Novelty Bath Salts Containing Methylone and Pentedrone

In recent years, a large number of designer drugs sold as “Bath Salts” have appeared on the market. In July of 2011, Raving Dragon Novelty Bath Salts was obtained over the Internet. This product became unavailable in October of that year coinciding with the DEA issuing a temporarily schedule of mephedrone, methylone, and MDPV. Four months later in February of 2012, a new product was released from the same company under the new name Raving Dragon Voodoo Dust. The contents of both products were identified using spectroscopy methods: nuclear magnetic resonance, infrared, UV–visible, tandem mass spectrometry, and high-resolution time-of-flight mass spectrometry. It was determined that Raving Dragon Novelty Bath Salts contained methylone. The replacement product Raving Dragon Voodoo Dust contained the unscheduled drug pentedrone. The Raving Dragon brand of products illustrates the rapid change of ingredients in these products to circumvent laws restricting availability, distribution, and use.     

Blowfly Larval Tissues as a Secondary Detector for Determining Paraquat-Related Death in Rabbit Carcass

Paraquat poisoning is commonly associated with suicide or homicide in Malaysia. In a case involving advanced body decomposition, pathological analysis regarding the cause of death may become difficult or almost impossible. Insects serve as common alternative matrix for poison detection in forensic analysis. Paraquat detection via secondary bioaccumulation in fly larvae tissue has never been reported. In this study, tissues from blowfly larvae collected from a rabbit carcass with paraquat poisoning were analyzed for secondary bioaccumulation. Larvae samples were collected and analyzed using liquid–liquid extraction. The detection was performed via reduction of quaternary ammonium presence in paraquat and analyzed using gas chromatography–mass spectrometry (GC-MS) with selected ion monitoring mode (SIM mode). GC-MS showed the elution of reduced paraquat was at retention time 12.8 min. Blowfly larvae tissue has proven useful as a secondary detector in paraquat-related deaths.     

Suicidal Fatality from Azide Ingestion

A 35-year-old man ingested an unknown amount of sodium azide and died within 2 h. The postmortem interval was 3 days. No alcohol or drugs were found in the blood and urine. Azide was derivatized in the peripheral blood, urine, and vitreous fluid with propionic anhydride. A portion of the headspace was injected onto a gas chromatograph with a nitrogen–phosphorus detector. Azide was quantitated in the peripheral blood (1.1 μg/mL), urine (7.5 μg/mL), and vitreous (43 μg/mL). The vitreous appears to be a better fluid for azide screening because of slower degradation.     

From Mosaic to Ebru: Conviviality in Multi-ethnic,Multi-faith Burgazadası, Istanbul

This paper provides an understanding of changing diversity in Burgazadas? within the post-Ottoman, homogenising context of Turkey. It critiques conceptualisations of ‘culture as difference’ within the multiculturalism discourse in Europe and of coexistence as the reduction of differences and identities to pre-existing categories of the Ottoman millet system. Instead, it presents post-Ottoman conviviality as a lived practice and grassroots representation of recognised and unrecognised diversities by contextualising the production of differences and changing discourses of pluralism. The article demonstrates that individuals belonging to different groups can come to share similar values based on longstanding attachment to place and everyday practices, thereby representing themselves, in this case, as ‘Burgazl?’.
