Forensic analysis of bicomponent fibers using infrared chemical imaging

The application of infrared chemical imaging to the analysis of bicomponent fibers was evaluated. Eleven nominally bicomponent fibers were examined either side-on or in cross-section. In six of the 11 samples, infrared chemical imaging was able to spatially resolve two spectroscopically distinct regions when the fibers were examined side-on. As well as yielding characteristic infrared spectra of each component, the technique also provided images that clearly illustrated the side-by-side configuration of these components in the fiber. In one case it was possible to prepare and image a cross-section of the fiber, but in general the preparation of fiber cross-sections proved very difficult. In five of the 11 samples, the infrared spectra could be used to identify the overall chemical composition of the fibers, according to a published classification scheme, but the fiber components could not be spatially resolved. Difficulties that are inherent to conventional "single-point" infrared spectroscopy, such as interference fringing and sloping baselines, particularly when analyzing acrylic type fibers, were also encountered in the infrared chemical image analysis of bicomponent fibers. A number of infrared sampling techniques were investigated to overcome these problems, and recommendations for the best sampling technique are given. Chemical imaging results were compared with those obtained using conventional fiber microscopy techniques.     

Applying social psychology: The case of redistributions in unified Germany

Large redistributions between West and East will be necessary within the unified Germany for a long time. The perceived justice of these redistributions is discussed, applying theory and evidence from social justice research and research on prosocial behavior. Views about just distributions and entitlements vary according to the preferred principles of distributions and according to attributions of responsibility for existing inequalities. It is, hypothesized that acceptance of redistributions in West Germany depends on whether the East is seen as having been unjustly disadvantaged after World War II when it was assigned to the influence sphere of the Soviet Union. This fact can be considered in analogy to an exploitation of the East by the West. On the other hand, the economic, problems in the East may also be considered self-inflicted by the former communist regime. A key question is what the attitudes of the population in the former GDR had been toward the communist regime. If the population is considered the victim of the regime, it is entitled to get support; if it is considered to have been sympathetic toward the regime, this is not the case. Acceptance of redistributions depends not only on their justice but also on their efficiency. The relative weight of justice and efficiency depends on the reasons given for the support. If support means repaying debts that were accumulated during the preceding period of being undeservedly privileged in the West, justice will remain the dominant criterion. If support is justified by actual neediness of the East, it will only be granted as help to self-help. Claims for discontinuity of support are expected if it will not be efficient in a near future. Some dangers concerning the integration of the two populations are outlined by listing some potential conditions for a growing distance and reciprocal discrimination up to a reciprocal ethnification between the Eastern and the Western populations.     

Organizational Readiness for Change in Correctional and Community Substance Abuse Programs

Significant needs exist for increased and better substance abuse treatment services in our nation's prisons. The TCU Organizational Readiness for Change (ORC) survey has been widely used in community-based treatment programs and evidence is accumulating for relationships between readiness for change and implementation of new clinical practices. Results of organizational surveys of correctional counselors from 12 programs in two states are compared with samples of community-based counselors. Correctional counselors perceived strong needs for new evidence-based practices but, compared to community counselors, reported fewer resources and less favorable organizational climates. These results have important implications for successfully implementing new practices.     

International trade policy in Israel: Another model — Reply

The aim of this study was to examine the tariff structure in Israel in terms of the four main theoretical models of endogenous commercial policy. The empirical results for levels of protection in Israel support several of the models. In particular the pressure group model performs well and especially the variable that represents the lobbying power of the Histadrut/public sector in Israel. This is consistent with the longstanding political power of the Histadrut in Israel. The Histadrut's role in the Israeli economy rises above the western concept of a labor union and takes on a quasi-governmental function. The clearest example of this elevated status is seen when the government included the Histadrut as part of the commission charged with the responsibility of carrying out the nominal liberalization process of the 1960s. Evidently it is this kind of political-economic power that allowed the Histadrut to affect the level of protection Histadrut-dominated industries received.The displacement costs model is also supported suggesting that officials, when deciding on tariff rates, are sensitive to the displacement costs (e.g., amount and average duration of unemployment), associated with different levels of protection for various industries. This result stands in contrast to the goals set out in the New Economics Policy of 1962 discussed earlier. Apparently tariff setting authorities desired to increase efficiency by reducing protection but were also willing, perhaps for political reasons, to trade off lower displacement costs with higher tariff rates.     

Political geography and Morgenthau’s early American works

The article is concerned with inconsistencies in Politics among nations (PAN) and Scientific man versus power politics in relation to statements on geopolitics. The article attempts to place these works in the internal and external context of the period in order to ascertain the reason for the inconsistencies. The analysis begins with the context of the chief academic debates in political geography at the time and proceeds to explain the source of the inconsistency between the two books, using the text and archival materials. Following this, the works and criticisms of Halford Mackinder, James Fairgrieve and Nicholas Spykman are examined. The external contextual elements of the Second World War, the beginning of the Cold War and the awakening of American global power are considered as factors in the shift towards a more favourable view on geographical considerations in international relations in PAN. The conclusion that the article reaches is that there are two factors which explain the inconsistency, the integration of American thought on international relations with Morgenthau’s own ideas and the diverging purpose of the books.
