Methodological reflections on media and counter hegemonic protest in India

This paper sets the issues and questions for interdisciplinary academic study of local protest with global claims,as it relates to use of the media. The author presents an historical background before then using the example of Arundhati Roy's writing on the Narmada Dams controversy and her essay 'walking with the comrades' on jungle Naxalite protest in India as a vehicle for analysis the uses of new Gramsci'ist counter hegemony theory, combined with elements of Judith Butler's ideas on performance and the media. What do these mean for activist articulations in the media

Gang Activity in English Prisons: The Prisoners’ Perspective.

Gang activity in American prisons has resulted in serious problems for prisoners and staff (e.g. Fong & Buentello 1991; Stevens 1997). This study assessed prisoners’ perceptions of gang-event frequency in the U.K. Interviews with 360 prisoners from 9 prisons in England and Wales indicated gang-related events were perceived as more frequent in all male categories of prison than they were in female institutions. Prisoners reported drug possession and prisoner groups being formed along regional origins as the most frequent gang related activities. Recidivists perceived higher levels of gang related activity than did first time prisoners. Gang related variables also predicted prisoners’ perceptions that groups of prisoners have more control over events in the prison than do staff and that order in the prison may not be maintained. The merits of interviewing prisoners and the implications of the results for maintaining order in prison are discussed

Group and intergroup parameters of gang activities: An introduction and research agenda.

In introducing this Special Issue on gangs, we overview the thrust of its papers, demonstrating how they assist in plugging research gaps from the dearth of psychological attention to gangs. The papers therein raise important theoretical considerations of group process effects, social identity, and communication influences in gangs. Also included are empirical examinations of how attitudes to formal organized crime groups may nurture progang views, how social networks bridge gang divides, the dehumanization and social dominance association with gang membership, and how membership longevity associates with gang members’ attitudes to their group. We conclude with theoretical prospects and empirical vistas for future work. For instance, vitality theory may help explain members’ immersion in gangs, discursive strategies could explain how youth are enticed into gangs, and examinations of community and law enforcement attitudes to gangs may provide insight into how oppositional attitudes are fostered on both sides of the gang divide

Business Investment and Employment Tax Incentives to Stimulate the Economy

[Excerpt] According to the Business Cycle Dating Committee of the National Bureau of Economic Research (NBER), the U.S. economy has been in recession since December 2007. Congress passed and the President signed an economic stimulus package, the American Recovery and Reinvestment Act of 2009 (P.L. 111-5), in February 2009. The $787 billion package included$286 billion in tax cuts to help stimulate the economy. Among the tax reductions, many were tax incentives directed to business. The preliminary estimate of third quarter real gross domestic product (GDP) growth is 2.8%; the unemployment rate, a lagging indicator, averaged 9.6% in the third quarter and 10.0% in the fourth quarter of 2009. Federal Reserve Chairman Ben Bernanke expects the economy to continue growing at a modest pace, but predicts that bank lending will remain constrained and the job market will remain weak into at least 2010. To further assist unemployed workers, help business, and stimulate housing markets, Congress passed the Worker, Homeownership, and Business Assistance Act of 2009 (P.L. 111-92). The Obama Administration has advocated further business tax incentives to spur investment and employment, especially for small business. The two most common measures to provide business tax incentives for new investment are investment tax credits and accelerated deductions for depreciation. The evidence, however, suggests that a business tax subsidy may not necessarily be the best choice for fiscal stimulus, largely because of the uncertainty of its success in stimulating aggregate demand. If such subsidies are used, however, the most effective short-run policy is probably a temporary investment subsidy. Permanent investment subsidies may distort the allocation of investment in the long run. Employment and wage subsidies are designed to increase employment directly by reducing a firm’s wage bill. The tax system is a frequently used means for providing employment subsidies. Most of the business tax incentives for hiring currently under discussion are modeled partially on the New Jobs Tax Credit (NJTC) from 1977 and 1978. Evidence provided in various studies suggests that incremental tax credits have the potential of increasing employment, but in practice may not be as effective in increasing employment as desired. There are several reasons why this may be the case. First, jobs tax credits are often complex and many employers, especially small businesses, may not want to incur the necessary record-keeping costs. Second, since eligibility for the tax credit is determined when the firm files the annual tax return, firms do not know if they are eligible for the credit at the time hiring decisions are made. Third, many firms may not even be aware of the availability of the tax credit until it is time to file a tax return. Lastly, product demand appears to be the primary determinant of hiring

What works for offenders and staff: Comparing two multi-agency approaches to offender resettlement

Between 2005 and 2007, the Kent and Medway Resettlement Programme (KMRP) piloted EXODUS (ex-offenders discharged under supervision), a multi-agency support system for identified prolific and priority offenders (IPPOs). Unlike traditional models of multi-agency support, EXODUS agencies work from the same location to maximize support for IPPOs, and inter- and intra-agency support for staff. This study assessed the perceived effectiveness of EXODUS. EXODUS staff and IPPOs were interviewed and their responses compared to those of traditional multi-agency support staff and IPPOs. Analysis showed that EXODUS IPPOs had committed fewer offences since receiving support than did comparison IPPOs. Neither group was more likely to be employed, but of those who were, EXODUS IPPOs were more likely to remain employed than comparison IPPOs. Most, regardless of type of support structure, recommended their programme and staff, although EXODUS IPPOs were more satisfied with the support they received. Staff believed that an expansion of the multi-agency approach was needed and that agency roles should be more clearly defined. EXODUS staff expressed higher efficacy in their own and colleagues’ ability to provide effective support and improved inter-agency relations and support from co-workers. However, EXODUS and comparison staff did not differ in levels of job satisfaction

Cancer Niche as a Garbage Disposal Machine: Implications of TCM-Mediated Balance of Body-Disease for Treatment of Cancer.

Cancer epidemic led to worldwide to search for a new "game changer" concept to govern cancer research and cancer treatment. Western medicine-based cancer research has been extending the impasse without resolution in sigh for improving survival of patients with solid malignant tumors in the last four decades due to heterogeneity in cancer tissues. Such a deadlock charts a course to learn lessons from the developing countries, directly or indirectly to complement the exhausted Western medicine. We propose a new concept of "Cancer niche as a garbage disposal machine" with implications of traditional Chinese medicine-mediated restoration of normal balance between body and disease to bring the fight against cancer under control

Incorporating a Spatial Prior into Nonlinear D-Bar EIT imaging for Complex Admittivities

Electrical Impedance Tomography (EIT) aims to recover the internal conductivity and permittivity distributions of a body from electrical measurements taken on electrodes on the surface of the body. The reconstruction task is a severely ill-posed nonlinear inverse problem that is highly sensitive to measurement noise and modeling errors. Regularized D-bar methods have shown great promise in producing noise-robust algorithms by employing a low-pass filtering of nonlinear (nonphysical) Fourier transform data specific to the EIT problem. Including prior data with the approximate locations of major organ boundaries in the scattering transform provides a means of extending the radius of the low-pass filter to include higher frequency components in the reconstruction, in particular, features that are known with high confidence. This information is additionally included in the system of D-bar equations with an independent regularization parameter from that of the extended scattering transform. In this paper, this approach is used in the 2-D D-bar method for admittivity (conductivity as well as permittivity) EIT imaging. Noise-robust reconstructions are presented for simulated EIT data on chest-shaped phantoms with a simulated pneumothorax and pleural effusion. No assumption of the pathology is used in the construction of the prior, yet the method still produces significant enhancements of the underlying pathology (pneumothorax or pleural effusion) even in the presence of strong noise.Comment: 18 pages, 10 figure

Information for the user in design of intelligent systems

Recommendations are made for improving intelligent system reliability and usability based on the use of information requirements in system development. Information requirements define the task-relevant messages exchanged between the intelligent system and the user by means of the user interface medium. Thus, these requirements affect the design of both the intelligent system and its user interface. Many difficulties that users have in interacting with intelligent systems are caused by information problems. These information problems result from the following: (1) not providing the right information to support domain tasks; and (2) not recognizing that using an intelligent system introduces new user supervisory tasks that require new types of information. These problems are especially prevalent in intelligent systems used for real-time space operations, where data problems and unexpected situations are common. Information problems can be solved by deriving information requirements from a description of user tasks. Using information requirements embeds human-computer interaction design into intelligent system prototyping, resulting in intelligent systems that are more robust and easier to use
