Environmental Scanning in High Velocity Environment.

Rai Niharika

Environmental scanning is the process of acquiring , interpreting and controlling flows of environmental information by the organizations in order not to be blindsided by threats, unprepared for opportunities, or ineffective in managing interdependencies with resource controllers and other important stakeholders. High velocity environment refers to a phenomenon in industries that exhibit perpetual state of change. The change triggering events are so dramatic that major portions of prior cognitive frameworks of the environment, which are traditionally highly resistant to change, are rendered ineffective in helping managers make sense of and act within the environment. In high velocity environments, quick adaptation to the environmental changes which in turn require quick noticing and interpretation of the environment stimuli, is a prerequisites for survival. This paper tries to understand the process of noticing and interpreting environment in an organization in a high velocity environment with the help of cognitive perspective of the environment where organizations enact on their environment.

An Analysis of Upward Influence Strategies Using Speech Act Theory and Face Threatening Acts

Asha Kaul and Brammer Charlotte

This study borrows from sociolinguistic research, specifically Speech Act Theory (SAT), as a way to analyze and explain how UI strategies are performed. Based on SAT and considerations of FACE, as explained by Brown and Levinson (1978/1987), we have attempted to provide an explanation for the choice of strategies used by members within the organization. Through qualitative discourse analysis, we suggest that for effective upward influencing, professional communicators need to consider the verbalization of UI strategies.

Building Bridges Between the Poor and the Banking System: A Study of Sanghamithra Rural Financial Services

Sriram M S

The paper is about Sanghamithra Rural Financial Services. It traces the growth of Sanghamithra from the time it was conceived till its completion of the fourth year of operations. It maps out how the strategic positioning of Sanghamithra has evolved and responded to external environment. It also traces the reasons for Sanghamithra to re-define its own role. Sanghamithra represents a unique experiment in the microfinance sector. It has important lessons on how an intermediary organisation can be structured, the impact it could have on the banking system, its own growth and sustainability. It raises issues of structuring organisations and also triggers a debate on whether the intent should be for-profit or not-for-profit. We conclude while the intent is important to choose the form of incorporation, while the nature of activities in itself does not dictate this intent and the consequent incorporation. We also discuss the issue of taxability. While there are arguments on the "charitable" nature of the operations of MFIs, we argue that these arguments are usually open to interpretation. If an institution has tax-free status as a non-negotiable part of its model, it may encounter regulatory roadblocks. This aspect is to be factored, while examining similar experiments. The paper also concludes that there is enough scope for an intermediary level organisation such as Sanghamithra to exist given the way the banking system is evolving and given the fairly inelastic nature of demand for credit vis-à-vis interest rates. It appears that access seems to be the prime concern while we deal with rural credit. However the paper recognises that this model is yet to build in a mechanism to collect "savings" of the clients. This is an issue worth pondering while structuring such intermediary organisations.

Financing issues in proposed HIV/AIDS intervention of providing anti-retroviral drugs to selected regions in India

Bhat Ramesh and Saha Somen

The development of antiretroviral therapy has given a new hope for people living with acquired immuno deficiency syndrome. In the face of increased disease burden due to HIV the global and political commitment towards controlling the pandemic has received renewed thrust in recent times. The Government of India has initiated antiretroviral treatment as a part of national public health programme in the six high-prevalence states. The aim of the paper is to provide the programme planners and other stakeholders, information about the impact of initiating antiretroviral therapy programme in the country. The paper discusses the global commitment towards fighting the disease in the light of the development in affordability and accessibility of antiretroviral drugs therapy. The paper highlights the importance of infrastructure and logistic requirement for developing a comprehensive treatment programme for the affected population in India. Finally, the paper has drawn broad financial implications of the antiretroviral therapy under different treatment scenarios. The estimated financial requirement for treatment vary from Rs. 92 crores per annum if focusing on 400,000 HIV/AIDs cases to identify patients requiring ARV Therapy to 1008 crores per annum if all 4 million patients are screened for coverage. Against this NACO has allocated total of Rs. 113 crores for treatment part of the proposed intervention. Even under the most conservative estimate achieving the treatment target in India with the proposed programme budget will be a challenging task.

Changing Context of Trade Mark Protection in India: A Review of the Trade Marks Act, 1999

Akhileshwar Pathak

With liberalisation and globalisation of the Indian economy, it has become possible for anyone to get into production and services in most of the sectors. This has led to rampant misuse and appropriation of trade marks. In an insulated economy, with monopoly markets, law protecting trade marks had a limited role. In the changed context, however, trade mark law will be a field of much interest for academics and practitioners. Towards this, the paper explores the formation of trade mark law in India. India has made a new trade mark law, the Trade Marks Act, 1999, which has come into effect from September 2003. This replaces the Trade and Merchandise Marks Act, 1958. The Act of 1958 had provided for registration of a trade mark in relation to particular goods falling in a specific class. A registered owner could prevent unauthorized use of the trade mark. The new Act has taken note of changes in trade and business practices. For example, it has included service marks and collective marks for registration; expanded the definition of a mark; and expanded the scope of 'infringement' of trade marks. While the previous Act discouraged protection to foreign marks, the new one has reversed this by giving special protection to 'Well known trade marks'. Further, foreign trade marks can be assigned and registered with very few restraints. In addition, the Act has strengthened civil and criminal liabilities for misusing trade marks.

Fan Charts as Useful 'Maps' for an Inflation-Targeting Central Bank: An Illustration of the Sveriges Riksbank's Method for Presenting Density Forecasts of Inflation

Vineet Virmani

In this study I illustrate the usefulness of Fan Charts for a central bank and show how they can be used to present its viewpoint on likely paths of future inflation. Exploiting a bivariate unobserved components model, I use the methodology followed by Blix and Sellin (1998) to demonstrate how subjective judgements can be systematically incorporated into model-based forecasts and effectively presented in a graphic manner.

Estimating Output Gap for the Indian Economy: Comparing Results from Unobserved-Components Models and the Hodrick-Prescott Filter

Vineet Virmani

Output gap estimates are constructed for India using unobserved components model (UCM) approach on the lines of Watson (1986) and Kuttner (1994). Results from UCMs are not found to be any less sensitive to data revisions when compared to those from the Hodrick-Prescott filter. This, however, could be because of lack of sufficient 'revised-data' on which the sensitivity of the results can be tested. Based on standard deviation of change in potential output to data revisions and its 'economic' content, the UCM using trimmed mean as the numeraire for inflation comes forth as the best choice. Alternative estimates of "core" inflation, included as a state variable in one of the UCMs, are also provided

Rainwater Harvesting, Alternative to the Water Supply in Indian Urban Areas: The Case of Ahmedabad in Gujarat

Akil Amiraly, Prime Nathalie, and Singh J P

Water scarcity is a characteristic of north-western states of India, such as Gujarat. Over time, the continuous increase of the population as well as the financial, administrative and technical deficiencies of the new supply system have lead to the deterioration of the water service in the city. In the meantime, the water demand has considerably increased due to the improvement of standards of living. This has resulted in an increasing pressure on underground water resources, which has lead to an alarming depletion of aquifers. From this overall situation arises the question of the use of complementary alternative sources of water in Ahmedabad and more particularly of the rehabilitation of the rainwater harvesting structures still existing in its old city area. The objective of the research is to evaluate to what extent this traditional system may constitute an additional source of water within the Old city of Ahmedabad and may locally reduce the pressure on water demand, assuming that the existing supply system does not fulfil the needs of the users. The results of an exploratory field study conducted in the Old city in 2001-02, which combined quantitative and qualitative aspects, give an outlook on people's opinions and behaviors regarding both systems. Finally, the rehabilitation of rainwater harvesting structures in the Old city of Ahmedabad suggests the necessity of empowering local structures of water management (households, non governmental association) in semi-arid urban areas to create the conditions for a sustainable implementation.
