Gas chromatographic-mass spectrometric analysis of buflomedil hydrochloride in biological samples after acute intoxication.

Two cases of acute intoxication of buflomedil hydrochloride are reported. The analysis of this compound was performed by an Extrelut extraction followed by a gas chromatographic-mass spectrometric determination. Analytical parameters of linearity, reproducibility and specificity were satisfactory.     

文化性的缺失—论课程的文化锁定现象

课程起源于化传承的需要，传递、复制、再生产社会化是学校课程唯一不变的使命。在课程发展中形成了特定的化锁定现象。它造成了课程应具有的自的化品性及其所必然引发的内在的、独立的价值标准与宗旨的消解。课程成了现实社会主流化的“代言人”。它具有诠释、粉饰及原样传递的职责，却无反思、批判、创新的品质。学校教育的工具品性、灌输与训练机制、教育教学理论的学术品质等，都是课程化锁定现象所造成的化性缺失的必然结果。揭示课程化性缺失的病理表征，是使课程由化的工具存在转变为化的主体存在的重要前题。     

The use of isoelectric focusing to identify rhinoceros keratins.

Keratins represent the principal structural proteins of hair. They are also found in horn, nail, claw, hoof, and feather. Hair and nail samples from human and canine sources and hair samples from mule deer, white tail deer, cat, moose, elk, antelope, caribou, raccoon, and goat were studied. Parrot and goose feathers were also analyzed. Keratins are polymorphic, and species differences are known to exist. Proteinaceous extracts of deer and antelope antlers and bovine and rhinoceros horn were prepared by solubilizing 10 mg of horn sample in 200 microL of a solution containing 12M urea, 74mM Trizma base, and 78mM dithiothreitol (DTT). Extraction took place over a 48-h period. A 25-microL aliquot of extract was removed and incubated with 5 microL of 0.1 M DTT for 10 min at 25 degrees C. Keratins were then separated by isoelectric focusing (IEF) on 5.2% polyacrylamide gels for 3 h and visualized using silver staining. At least 20 bands could be observed for each species studied. However, band patterns differed in the position of each band, in the number of bands, and in band coloration resulting from the silver staining process. Horn from two species of rhinoceros was examined. For both specimens, most bands occurred in the pH range of 4 to 5. Although similar patterns for both species were observed, they differed sufficiently to differentiate one from the other. As might be expected, the closer two species are related phylogenetically, the greater the similarity in the IEF pattern produced from their solubilized keratin.(ABSTRACT TRUNCATED AT 250 WORDS)     

A discriminant function analysis of deciduous teeth to determine sex

Studies of deciduous teeth have concluded that crown size differences in these teeth between males and females are not reliable sex discriminators, in contrast to such differences in permanent teeth. This study measured the mesiodistal and faciolingual crown diameters of all deciduous teeth, as well as those of the permanent first molars, of 162 children from the Burlington Orthodontic Growth Study, conducted earlier in Burlington, Ontario, Canada. All 40 deciduous tooth diameters (20 mesiolingual and 20 faciolingual) were significantly different between the sexes, as were the permanent tooth diameters. Using three to five measurements of deciduous teeth, discriminant analyses of several samplings of these children produced discriminant functions in which 76 to 90% of the holdout samples were correctly classified by sex. Combinations of deciduous and permanent measurements were used to classify 83 to 85% of the holdout samples correctly. When compared with published data on other sample populations, the Burlington group is the most dimorphic for deciduous teeth and is within the range of permanent tooth dimorphisms of other populations. The level of classification accuracy, when using discriminant analysis of the deciduous teeth, can approach the accuracy levels of analysis using the permanent teeth.     

Is informalization equalizing? Evidence from Kinshasa (DRC)

As a consequence of a concatenation of external and internal events, the economy of the Democratic Republic of the Congo (DRC) has informalized to an unprecedented level over the last few decades. A comparison of budget surveys carried out in 1975 and 2004 respectively allows us to ascertain the effect of this process on income inequality and poverty in Kinshasa. We find that the extent of inequality in the capital city of the DRC has remained largely unchanged, which strongly suggests that informalization has been a viable survival strategy for those at the lower-income end of society. Unexpectedly, whereas distinctions such as gender and age lost much of their profiling power in the period considered, other cleavages such as education and geography, which may be assumed to be much more intimately related to the formal sector, continued to play an important role in structuring inequality in Kinshasa’s deeply informalized economy.     

The Unintended Consequences of the Transatlantic Trade and Investment Partnership Negotiations

ABSTRACT

Although stalled since 2016, the negotiations on a Transatlantic Trade and Investment Partnership (TTIP) have had major unintended consequences. The TTIP led to demands from third countries to upgrade their trade relationship with the EU and to unprecedented politicisation. As second-order effects of the latter, it endangered the EU-Canada trade agreement and brought about reform of EU trade governance and amendments to EU trade policy positions. These unintended consequences occurred because of inflated expectations about and insufficient awareness of the different nature of TTIP with regard to scope and partner compared to other trade negotiations. In the meantime, EU trade policy has adapted to the new politics of trade, making unintended consequences less likely.     

Left and right among local elites: Comparative figures from Switzerland,Spain, Germany and the Netherlands

This paper examines whether or not the classical ideological cleavage — the left—right dimension — is still valid and determines the choices made in politics. It looks at the extent to which the left‐right concept features in the views of local elites in four European countries. A strong relation is found between the left‐right self‐placement of local elites and their party membership, their opinion about income distribution, the role of government and economic growth. The left‐right dimension is still relevant in the belief system of local elites, but does not determine day‐to‐day decisions. Six factors are discussed which might explain these findings: the validity of this research; the specific characteristics of local‐level policy making; differences between politicians and public administrators; the fragmentation of local politics; the theory on latent and manifest ideologies by Bluhm; and the consensus theory of Wildavsky. It is concluded that more research is needed to test the last two theories, because they seem to be the most promising.     

Steuerung jenseits von Hierarchie

The paper sheds new light on recent debates about governance and approaches contemporary problems of governing from the perspective of contemporary theories of power. The concept of “soft governing” is developed in order to capture horizontal mechanisms of power intentionally used to govern beyond formalised hierarchies characteristic of processes of governance. The paper describes in particular the horizontal forms of governing through discursive practices, argumentation and symbols and the ways in which they interact. The example of campaigns against female genital mutilation is introduced in order to illustrate possible forms of governing beyond hierarchy.
