Atomic force microscopic investigation of commercial pressure sensitive adhesives for forensic analysis

Pressure sensitive adhesive (PSA), such as those used in packaging and adhesive tapes, are very often encountered in forensic investigations. In criminal activities, packaging tapes may be used for sealing packets containing drugs, explosive devices, or questioned documents, while adhesive and electrical tapes are used occasionally in kidnapping cases. In this work, the potential of using atomic force microscopy (AFM) in both imaging and force mapping (FM) modes to derive additional analytical information from PSAs is demonstrated. AFM has been used to illustrate differences in the ultrastructural and nanomechanical properties of three visually distinguishable commercial PSAs to first test the feasibility of using this technique. Subsequently, AFM was used to detect nanoscopic differences between three visually indistinguishable PSAs.     

Decapitation in road traffic accident--a case report

A 20-year-old girl along with four of her friends, all in their early 20s, met with a fatal accident in the early hours of the day. Their car was hit by a speeding truck at a crossing. All the occupants of the car sustained multiple injuries and died on the spot. The girl was decapitated in the accident. Her head was recovered outside the mangled remains of the vehicle and the rest of the body was extracted from the co-driver's seat of the damaged vehicle.     

Economic changes during the Indian emergency

Abstract

North Korea (or the Democratic People's Republic of Korea—DPRK), more than any other industrial country, is a terra incognita in the Western consciousness. Most commonly it is abhorred as the embodiment of the irrational, the fanatical, and the threatening, and even among Western progressives it is dismissed as grotesque and/or irrelevant. Yet it is an important country and one that deserves close attention.     

Anatomy of a massacre: the roots of heightened labour militancy in South Africa’s platinum belt

Abstract

On 16 August 2012, a protracted strike at a platinum mine in Marikana, South Africa, culminated in the killing of 34 mineworkers by local security forces. Some viewed this tragedy through the lens of South Africa’s apartheid past, recalling such events as the Sharpeville massacre of 1960. Others saw this episode as the latest cycle of angry protest and violent repression stemming from heightened inequality and poverty under global capitalism. This paper explores a set of institutional factors that occupy the middle ground between these two narratives about the massacre at Marikana. At the national level, despite progressive labour regulations and a long-standing alliance between the leading trade union (COSATU) and the ruling African National Congress, institutional channels for social dialogue and collective bargaining were less effective than expected given COSATU's inability to criticize policies focused on business-led growth at the expense of the social protection of workers. At the sectoral level, gigantic platinum companies faced with falling commodity prices sought to limit losses by planning retrenchments and limiting wage increases, triggering repeated and sometimes violent wildcat strikes, especially when workers’ grievances were set aside by local representatives of the COSATU-affiliated National Union of Mineworkers. The argument may be seen as a labour-focused variant of Huntington’s ‘gap hypothesis’: workers’ militancy has grown as existing institutional frameworks for ensuring labour peace have failed to effectively channel the frustrations of workers most in need of social protection.     

The demographic correlates of admissions to the child and adolescent inpatient clinic at a midwestern metropolitan mental health complex

Using the data from the 1970 census of population and housing for the Standard Metropolitan Statistical Area (SMSA) of Milwaukee, Wisconsin, demographic information was recorded for each of the approximately 300 census tracts in the Milwaukee County pertaining to population characteristics, marital status, age stratification, economic characteristics, and housing characteristics. Also, information was collected on number of admissions into the child and adolescent inpatient clinic for each census tract. The 300 census tracts were then divided into four categories: very low admission, low admission, high admission, and very high admission. Using a computer method, a demographic analysis of these four groups of census tracts was then carried out to examine the correlation between the density of admissions and various demographic characteristics. During the course of the study, various correlations between high admissions to the child and adolescent psychiatric inpatient clinic and various demographic characteristics emerged. Implications of these findings, in terms of present service and future planning, are discussed.Received his medical training in India, his psychiatric training in England, and has practiced in the United States since 1976. Current interests are psychoanalytic psychiatry and the epidemiologic aspects of mental health.     

Re-reading the Indian Emergency: Britain,the United States and India’s Constitutional Autocracy, 1975–1977

The period known as the “Emergency” in India—June 1975 to March 1977—is widely recognised as one of the darkest episodes in the nation’s 70-year history. Fundamental rights were suspended, whilst the courts had little or no authority. The security services received emergency powers to make arrests without explanation. Although the political, social, and economic history of the Emergency remains well known, there is nothing on the international history of this period. This analysis provides the first contribution to its diplomatic history. Examining the role played by the United States and Britain, in particular, finds basis largely on declassified papers available in the Indian, American, and British national archives as well as a survey of over 300 newspaper articles on and around the Indian Emergency.     

Communist Legacies, Postcommunist Transformations, and the Fate of Organized Labor in Russia and China

This study aims to generate fresh hypotheses concerning emergent variations in labor politics across postcomunist settings. Although labor may be weak throughout the postcommunist world, a historical comparison of labor politics in Russia and China reveals consequential differences in the extent and sources of union weakness. Taking these differences seriously, the study asks why organized labor in Russia—in spite of a steeper decline in union membership, greater fragmentation, and a conspicuously low level of militancy—wasrelatively more effective in advancing working-class interests during economic liberalization than the growing, organizationally unified trade union apparatus in China. The comparisons suggest that some constraints on organized labor are more malleable than others, allowing for openins where labor can affect outcomes in ways that surprise, if not scare, state and business. Specifically, key differences in historical legacies and in the pace and ynamics of institutional transformation have conferred upon Russian unions key organizational, material, and symbolic resources that Chinese unions do not possess to the same degree. These differences reflect mechanisms capable of generating increasingly divergent prospects for organized labor mobilization over long-time horizons.
