Dynamic internet pricing with service level agreements for multihomed clients

With the increase in internet coverage and the decrease in internet access price, the demand for good internet service has grown. Clients expect a guarantee in the quality of service (QoS) during internet access. In this paper, we present a model in which clients are given assurances by service providers to be able to connect to the internet and to get the bandwidth requested, and, if clients do not get the services they request, the service provider pays penalties to the clients. We consider internet clients that can dynamically connect to a number of internet service providers (ISP). When a client arrives at an ISP, he has to decide whether to accept the client, and then the price to charge from the client for the duration of its connection. Rejection of a client results in a penalty and delay in getting the requested bandwidth also incurs a penalty. We assume a Poisson arrival process with the rate of arrival sensitive to the price being charged. A client requests bandwidth for a time that is exponentially distributed, then the client is idle for a time that is also exponentially distributed; and then either the client departs or requests bandwidth again after the idle period is over. A service provider tries to maximize its income by charging appropriate prices based on its current state and deciding whether to accept more clients or not. Since penalties are imposed, such solutions also automatically balance load among service providers, and so the QoS to clients improves. We present solutions that maximize the income of service providers. The solutions are then compared using simulation. Simulation results show that our solutions significantly improve QoS of clients and increase the income of service providers as compared to a simple heuristic based solution that could otherwise be used.     

Costs associated with adverse events in patients with metastatic renal cell carcinoma

Objective:

To estimate adverse event (AE) costs in patients receiving targeted therapies for the first line treatment of metastatic renal cell carcinoma (mRCC).

Methods:

Retrospective study based on healthcare claims data for patients with mRCC, aged ≥18 years, receiving first-line treatment with targeted therapies. AEs of interest comprised of abdominal pain, back pain, diarrhea, dyspnea, extremity pain, fatigue/asthenia, hand-foot syndrome, hypertension, lymphopenia, nausea/vomiting, neutropenia, proteinuria, and thrombocytopenia. Healthcare encounters for AEs were based on ICD-9-CM diagnosis/procedure codes on healthcare claims. AE costs were examined over a 30-day period, beginning with the date of first mention of AE, and were estimated based on the difference in total costs between patients with and without events. Drug costs of targeted agents were excluded from the analysis. Multivariate generalized linear models with a log-link function and gamma response probability distribution were utilized to control for differences in baseline characteristics between patients with and without evidence of AEs.

Results:

A total of 533 patients were included in this analysis: 418 patients with AE and 115 patients without AE. Baseline characteristics were generally similar between patients in the two groups. The GLM-based estimate of incremental 30-day post-event costs among patients with evidence of any adverse events was $9807 (95% CI?=?$4386–$22,947). For all types of adverse events examined, the estimated difference in costs between evented and non-evented patients was positive; the 95% CI did not include zero for all of the adverse events considered, except hypertension and proteinurea. Study limitations include errors of commission/omission, especially as they may affect case-finding methods that rely on ICD-9-CM diagnosis and procedure codes, as was the case in the current study.

Conclusion:

Costs associated with AEs of first-line targeted therapies are substantial in patients with mRCC. Efforts to prevent and/or better manage these events may reduce overall healthcare costs.     

Consuming postcolonial shopping malls

Abstract

Through a naturalistic inquiry, we interpret shopping malls in India as post-colonial sites in which young consumers deploy the West in an attempt to transform their Third World identities. Shopping malls in former colonies represent a post-colonial hybridity that offers consumers the illusion of being Western, modern, and developed. Moreover, consumption of post-colonial retail arenas is characterised as a masquerade through which young consumers attempt to disguise or temporarily transcend their Third World realities. This interpretation helps us to offer insights into transitioning retail servicescapes of the Third World, which in turn helps to improve extant understanding of consumer identity and global consumer culture.     

Underdeveloped Other in country-of-origin theory and practices

Consumers and marketers employ extant sociocultural discourses to give meaning to the products they consume or sell. In this paper, we present data and analyses that illustrate the manner by which American consumers and marketers draw upon one such sociocultural discourse, development, in the context of “craft” objects. Beyond the focus on discourse, however, our intent is to apply a post-development perspective to the Otherness inherent in country-of-origin (COO) theory and practices. We critique the COO framework and see it as a ramification of, and further creator of, economic difference and hierarchy.     

How to make India a knowledge-based society

The National Knowledge Commission set up by the Prime Minister of India, Dr. Manmohan Singh, in 2005 was, perhaps, the first of its kind. One of its three objectives is to make India a knowledge-based society. Among the important areas in the country where problems need to be addressed to achieve the above objective, three—education, knowledge empowerment of Panchayats (the lowest of the three-tier local self-government system in India), and ethical commercialization of the country's creative and cultural tradition—are briefly described in the article. Some steps that need to be taken in each area are stated. For example, in regard to education, we must decommercialize school and higher education, and set up 400,000 high schools in the country where children would receive high-quality free education for 10 years—that is, up to the age of 16. As regards the Panchayats, we need to institute a system so that they are empowered through knowledge in areas of immediate interest to them as well as knowledge that would make them truly informed citizens of the country. In regard to traditional knowledge, it needs to be ensured that the keepers and practitioners of this knowledge are compensated adequately and fairly if such knowledge is commercialized.     

Work alienation of marketing employees: Influence of task,supervisory, and organizational structure factors

This study presents an integrated work alienation model that includes a number of relevant exogenous antecedents from the task, supervisory, and organizational structure domains. The study hypothesizes that these antecedents influence work alienation of marketing employees both directly and indirectly because of the effects they have on employees’ role stress and commitment to the organization. Simultaneous inclusion of relevant antecedents enables the study to establish the relative importance of each antecedent for work alienation of employees. The study also includes a comparative evaluation of the applicability of the proposed model for subgroups of employees stratified by gender.

A STEINDLIAN MODEL OF CONCENTRATION,DEBT AND GROWTH

Income distribution plays a crucial role in the Kaleckian models of growth. The recent US experience has seemingly turned the Kaleckian argument on stagnationism on its head. Does it, therefore, render the Kaleckian growth framework redundant? We argue that while there is a tendency towards underconsumption, there could be other counteracting tendencies like the wealth effect of the capitalists or the possibility of debt for the workers. But such a growth process, which is primarily driven by the asset price markets, is, by its very nature, iniquitous and extremely volatile and the downturn is far more severe than the normal business cycles.     

FINANCING SMALL-FARM DEVELOPMENT IN INDIA*

Small farm credit is important in public programs of developing countries. It is supported to finance increased productivity through modernization and to replace the exploitive moneylender. However, expectations often exceed performance. Indian research suggests the discrepancy may be traced to failure to account for the needs of liquidity management. It suggests, too, that programs that are designed to account for liquidity management can lead to modernization and to improved viability of small farms as well.
