    The article focuses on the origins, context, and political significance of Adamson Mushala's rebellion against the Zambian one-party state. While making no substantial military gains, Mushala succeeded in destabilizing the North-Western Province, the site of his insurgency, and creating an atmosphere of fear and paranoia among local and national leaders of the ruling United National Independence Party (UNIP). The Zambian postcolonial state was threatened by the enduring relevance of such allegiances. Mushala capitalized on the strength of local systems of ethnic affiliation, following in the footsteps of chieftain authorities, who had expressed their rejection of UNIP's national project by leading their people across the barely visible colonial borders separating an enduring Lunda polit

    Cover Text Steganography: N-gram and Entropy-based Approach

    Get PDF
    Steganography is an ancient technique for hiding a secret message within ordinary looking messages or objects (e.g., images), also known as cover messages. Among various techniques, hiding text data in plain text file is a challenging task due to lack of redundant information. This paper proposes two new approaches to embed a secret message in a cover text document. The two approaches are n-gram and entropy metric-based generation of stego text. We provide examples of encoding secret messages in a cover text document followed by an initial evaluation of how well stego texts look close to the plain texts. Furthermore, we also discuss several related work as well as our future work plan

    A standard overarm tracing lathe converted by the addition of an independently driven diamond grinding wheel is used for grinding aspheric surfaces. The motion of the wheel is controlled by the lathe air tracer following the template which produces the desired aspheric profile

    Loneliness in men 60 years and over : the association with purpose in life

    Loneliness as a consequence of getting older negatively impacts on the health and well-being of men as they age. Having a purpose in life may mitigate loneliness and therefore positively impact on health and well-being. Limited research into loneliness and purpose in life has been undertaken in older men. This study seeks to understand the relationship between loneliness and purpose in life in a group of older men. Using data from a cross-sectional survey of 614 men aged 60 years and over living in New Zealand, bivariate and multivariate analyses were undertaken to examine the relationship between loneliness and purpose in life using a range of demographic, health, and social connection variables. Bivariate analysis revealed that being unpartnered and having low socioeconomic status, limited social networks, low levels of participation, and mental health issues were associated with loneliness. Multivariate analysis showed that having poor mental health and lower purpose in life were indicators of loneliness. Consequently, improving mental health and purpose in life are likely to reduce loneliness in at-risk older men. As older men are a heterogeneous group from a variety of sociocultural and ethnic backgrounds, a multidimensional approach to any intervention initiatives needs to occur

    The changing role of china in the global illegal cigarette trade

    Get PDF
    This study explores the history of the illegal production, distribution, and smuggling of cigarettes in mainland China. Data were obtained from a content analysis of 931 media reports retrieved from LexisNexis for the time period 1975 until 2010, and from other open sources. The illegal cigarette trade first emerged in the form of violations of state tobacco monopoly regulations. In the course of the restructuring of the legal tobacco sector, which occurred under external political pressure to open the Chinese market to foreign competition, an illegal cigarette industry emerged which at first primarily produced fake Chinese brand cigarettes for the domestic black market. At the same time, China became a destination country for smuggled genuine Western brand cigarettes. It was only after effective crackdowns against cigarette smuggling and domestic distribution channels in the late 1990s that the Chinese illegal cigarette industry shifted to exporting large numbers of counterfeit Western brand cigarettes to black markets abroad. China’s current role as a leading supplier of counterfeit cigarettes is a result of the contradictions of the economic reform process and of external licit and illicit forces that worked toward opening up the Chinese tobacco sector to the outside world
