TL;DR: In this article, the authors provide an exploratory analysis of the importance of word of mouth and the factors which influence its role within an organisation's mark, and they highlight the significance of personal recommendation.
Abstract: Financial service providers have long placed considerable faith in positive word of mouth communication as a means of attracting new customers and a variety of studies of customer choice of bank highlight the significance of personal recommendation. Given that financial services tend to be characterised by a predominance of experience and credence qualities, word of mouth communication is particularly valuable, providing the potential consumer with vicarious experience of the service under consideration. The impact of word of mouth is probably at its strongest when it originates from social contacts because of their greater perceived reliability. By its very nature, this form of communication is outside the formal control of an organisation and yet its impact is such that the ability to influence or encourage word of mouth could be a powerful marketing tool. This paper provides an exploratory analysis of the importance of word of mouth and the factors which influence its role within an organisation’s mark...

TL;DR: In this paper, the authors investigated the relation between need for cognition of individuals and their effectiveness in solving complex problems and found that individuals with a higher need for cognitive skills were more successful in solving the problem, collected information and made decisions on more aspects of the problem and faced fewer crises during the process.

TL;DR: In this paper, the equivalence of second order quantile matching priors and highest posterior density regions matching prior within the class of first-order quantile priors was established.
Abstract: The paper has three components. First, for a realvalued parameter of interest orthogonal (Cox and Reid, 1987) to the nuisance parameter vector, we find a necessary and sufficient condition for the equivalence of second order quantile matching priors and highest posterior density regions matching priors within the class of first order quantile matching priors. Examples are presented to illustrate the result. Second, we develop a quantile matching prior in a normal hierarchical Bayesian model. This prior turns out to be different from the one proposed earlier by Morris (1983). Third, we obtain an exact matching result when the objective is prediction of a real-valued random variable from a location family of distributions.AMS (2000) Subject Classification: 62F15, 62F25, 62E20

TL;DR: In this article, the bounded risk sequential estimation problem of the location parameter is considered under an asymmetric linex loss funmction, and an asymptotic second-order expansion of the risk function is derived for a general class of stopping variables.
Abstract: For a two-parameter negative exponential population with both parameters unknown, the bounded risk sequential estimation problem of the location parameter is considered under an asymmetric linex loss funmction. Asymptotic second-order expansion of the risk function is derived for a general class of stopping variables. Some examples are include involving purely scquential and accelerated sequential sampling methodologies. A Monte-Carlo study is carried out to support the asymptotic results and to compare the performance of the different sampling methodologies.

TL;DR: In this paper, an attempt has been made to re-examine the inscriptions of Ashoka, an ancient Indian king who was a great leader, well known in history, who had the courage, confidence, vision and will to provide an administration based purely on genuine human values.
Abstract: An attempt has been made in this article to re-examine the inscriptions of Ashoka, an ancient Indian king, who was a great leader, well known in history, who had the courage, confidence, vision and will to provide an administration based purely on genuine human values. As evidenced in his inscriptions, 'effective leadership' depends not on preaching moral values but on practising them, and modifying life and leadership styles accordingly. Ashoka believed that the success of a true leader is directly related to the maintenance of purity in public life and harmony in domestic affairs.

TL;DR: In this article, the authors investigated a new family of goodness-of-fit tests based on the negative exponential disparities, which includes the popular Pearson's chi-square as a member and is a subclass of the general class of disparity tests (Basu and Sarkar, 1994).
Abstract: This paper investigates a new family of goodness-of-fit tests based on the negative exponential disparities. This family includes the popular Pearson's chi-square as a member and is a subclass of the general class of disparity tests (Basu and Sarkar, 1994) which also contains the family of power divergence statistics. Pitman efficiency and finite sample power comparisons between different members of this new family are made. Three asymptotic approximations of the exact null distributions of the negative exponential disparity famiiy of tests are discussed. Some numerical results on the small sample perfomance of this family of tests are presented for the symmetric null hypothesis. It is shown that the negative exponential disparity famiiy, Like the power divergence family, produces a new goodness-of-fit test statistic that can be a very attractive alternative to the Pearson's chi-square. Some numerical results suggest that, application of this test statistic, as an alternative to Pearson's chi-square, coul...

TL;DR: In this article, the problem of estimating a linear function of k normal means with unknown variances is considered under an asymmetric loss function such that the associated risk is bounded from above by a known quantity.
Abstract: The problem of estimating a linear function of k normal means with unknown variances is considered under an asymmetric loss function such that the associated risk is bounded from above by a known quantity. In the absence of a fixed sample size rule, sequential stopping rules satisfying a general set of assumptions are considered. Two estimators are proposed and second-order asymptotic expansions of their risk functions are derived. It is shown that the usual estimator, namely the linear function of the sample means, is asymptotically inadmissible, being dominated by a shrinkage-type estimator. An example illustrates the use of different multistage sampling schemes and provides asymptotic expansions of the risk functions.

TL;DR: In this paper, the authors explored the pre-alliance imperatives by generating a set of transaction-specific variables and a sequential order integrating the content and process issues and found that the variables have different predictive strengths in the two countries and the ideal sequential order was different from the actual order followed.
Abstract: This was a study of 22 U.S. and 26 Indian organizations operating as alliance partners in India. With data from 109 U.S. and 114 Indian managers, we explored the pre-alliance imperatives by generating a set of transaction-specific variables and a sequential order integrating the content and process issues. The variables were found to have different predictive strengths in the two countries and the ideal sequential order was different from the actual order followed. The report highlights the implications of the study for international management.

TL;DR: In this paper, the authors investigated the pattern of energy consumption changes during reform period i.e., 1991-92 to 1996-97 and various factors responsible for these changes based on Input/Output model.
Abstract: India's economic reform was initiated in mid 1991 by the Government of India. Some strategies for energy sector were adopted. This paper investigates the pattern of energy consumption changes during reform period i.e., 1991-92 to 1996-97and various factors responsible for these changes based on Input/Output model. Here we develop a Structural Decomposition Analysis. Six different factors have been identified here: (i) Technical changes, (ii) Changes in final demand structure, (iii) Changes in the interaction term of technical changes and final demand structure, (iv) Changes in energy exports, (v) Changes in energy imports, (vi) Changes in energy change in stock. Then we separate technical changes and final demand structure again, which explain the energy consumption changes. The most significant role as revealed from the empirical results have been played by the final demand structure, technical changes and interaction term between final demand structure and technical changes.
