Abstract

This chapter shifts contemporary debates on Eurocentrism from its focus on European social theory to an analysis of its moorings in non-Atlantic sociological traditions and especially those within ex-colonial countries. It discusses the sociological/anthropological visions of two first generation sociologists/anthropologists from India, G. S. Ghurye (1893–1983) and D. P. Mukerji (1894–1961), within Orientalist-Eurocentric positions and explores how these are reinvented in the work of contemporary sociologist T. N. Madan (1933–). It suggests that colonial processes and its institutions together with “derivative” nationalist ideas have played and continue to play important mediatory role in organizing these Orientalist-Eurocentric visions.

The chapter presents three sets of arguments. First it suggests that in order to understand postcolonialism it is imperative to lay out the organic links between Orientalism and Eurocentrism. Eurocentrism and its mirror Orientalism mediated to frame social science language in terms of the binaries of universal (the West) and particular (the East). The particular was represented in India through the discipline of anthropology. The latter studied “traditions” through the themes of religion, caste, and family and kinship. When sociology emerged as a discipline in India in the early twentieth century, it continued to use the language organized by anthropology to analyze the particular cultural traditions of the country. Second, I suggest that these binaries also framed nationalist thought and the latter mediated in framing the sociological ideas of G. S. Ghurye and D. P. Mukerji which were embedded in Eurocentric-Orientalist principles. Third, I analyze the ideas of the contemporary social theorist T. N. Madan to indicate how his perspective continues to derive its positions from Orientalist-Eurocentric positions and ignores an engagement with critics who have questioned Orientalist Eurocentrism. Disregarding these arguments implies the legitimation of the latter perspective derived from the disciplines of sociology/anthropology.

The chapter contends that a decolonized critique of colonial social science has existed in other regions of the world including India, and that this perspective needs to be retrieved by social theorists to reformulate the sociological discourse as a study of modern India. It also suggests that contemporary analysis of Eurocentrism needs to move out from within the circuits of knowledge defined by received colonial geopolitical enclaves in order to assess the way production, distribution, and consumption of Orientalist-Eurocentric perspectives have organized sociological traditions across the world including the Global South.

Abstract

Purpose

Functionally graded materials are a special class of composites in which material are graded either continuously or layered wise depending upon its applications. With such variations of materials, the properties of structure vary either lengthwise or thickness wise. This paper aims to investigate models for effective estimation of material properties, as it is necessary for industries to identify the properties of composites or functionally graded materials (FGM’s) before manufacturing and also to develop novel material combinations.

Design/methodology/approach

Available models were compared for different material combinations and tested with experimental data for properties such as Young’s modulus, density, coefficient of thermal expansion (CTE) and thermal conductivity. Combinations of metal–ceramic and metal–metal were selected such that their ratios cover a wide range of materials.

Findings

This study reveals different models will be required depending on the material used and properties to be identified.

Practical implications

The results of the present work will help researchers in the effective modeling of composites or FGM’s for any analysis.

Originality/value

This paper presents a comparison and review of various analytical methods with experimental data graphically to find out the best suitable method. For the first time, the Halpin-Tsai model was extended in the analysis of the CTE which shows good approximations.

Abstract

Purpose

The purpose of this study is to investigate Thermo-mechanical limit elastic speed analysis of functionally graded (FG) rotating disks with the temperature-dependent material properties. Three different material models i.e. power law, sigmoid law and exponential law, along with varying disk profiles, namely, uniform thickness, tapered and exponential disk was considered.

Design/methodology/approach

The methodology adopted was variational principle wherein the solution was obtained by Galerkin’s error minimization principle. The Young’s modulus, coefficient of thermal expansion and yield stress variation were considered temperature-dependent.

Findings

The study shows a substantial increase in limit speed as disk profiles change from uniform thickness to exponentially varying thickness. At any radius in a disk, the difference in von Mises stress and yield strength shows the remaining stress-bearing capacity of material at that location.

Practical implications

Rotating disks are irreplaceable components in machinery and are used widely from power transmission assemblies (for example, gas turbine disks in an aircraft) to energy storage devices. During operations, these structures are mainly subjected to a combination of mechanical and thermal loadings.

Originality/value

The findings of the present study illustrate the best material models and their grading index, desired for the fabrication of uniform, as well as varying FG disks. Finite element analysis has been performed to validate the present study and good agreement between both the methods is seen.

Abstract

Asset allocation has primarily focused its attention on attaining mean variance efficiency by employing diversification strategies following the portfolio selection methodologies of Markowitz[1952]. These are important principles that have given rise to a large variety of diversified investment choices in mutual funds that now outnumber the available choices for investment in stocks. Paralleling this development has been a growing interest in the second odd moment describing returns, the level of skewness. The empirical stability of return skewness has been noted in Beedles and Simkowitz[1980]. Earlier, the importance of skewness for portfolio selection was studied by Arditi and Levy[1975] and Kraus and Litzenberger[1976]. More recently, motivated by the persistence skews observed in option markets (Bates[1991]), Bakshi Kapadia, and Madan [2000] take up the issue of studying the links between the statistical and risk neutral skews, while Harvey and Siddique[1999] address the asset pricing implications of investor preferences for skewness. Evidence is also presented by Carr, Geman, Madan, and Yor [2000] that the primary model for diversified returns is that of a pure jump return process reflecting both, excess kurtosis and skewness.

Abstract

Purpose

The purpose of this paper is to frame the guidelines for brand building for micro, small and medium enterprises (MSMEs) and evaluate the role of the entrepreneur in the brand management process.

Design/methodology/approach

A qualitative study comprising in-depth interviews of 20 Indian MSME entrepreneurs who had experience with brand-building was conducted. The entrepreneurs were probed regarding the brand management process and their role in the brand-building efforts in their organization. The guidelines that emerged from the study were compared and contrasted with those proposed in Krake’s model, and a new model for brand-building is proposed.

Findings

The improvised new model highlights the importance of “name of the brand”, “managing finance simultaneously” and “exit strategy” as important factors for the creation of a successful brand, amongst other factors revealed in extant literature. The interviews also reveal that an MSME headed by a passionate entrepreneur who accommodates professional expertise witnesses a greater chance of success.

Originality/value

In spite of the growing importance of SMEs, scant attention has been paid to the issue of branding in SMEs. This study contributes to the literature on branding and small business research by examining and advancing the brand-building guidelines developed by Krake. It further looks at the role of the entrepreneur in the entire process of brand building in the increasingly evolving Indian market.

Abstract

Purpose

The purpose of this paper is to provide a better understanding of the reasons why people use or do not use carpooling. A further aim is to collect and analyze empirical evidence concerning the advantages and disadvantages of carpooling.

Design/methodology/approach

A large-scale text analytics study has been conducted: the collection of the peoples’ opinions have been realized on Twitter by means of a dedicated web crawler, named “Twitter4J.” After their mining, the collected data have been treated through a sentiment analysis realized by means of “SentiWordNet.”

Findings

The big data analysis identified the 12 most frequently used concepts about carpooling by Twitter’s users: seven advantages (economic efficiency, environmental efficiency, comfort, traffic, socialization, reliability, curiosity) and five disadvantages (lack of effectiveness, lack of flexibility, lack of privacy, danger, lack of trust).

Research limitations/implications

Although the sample is particularly large (10 percent of the data flow published on Twitter from all over the world in about one year), the automated collection of people’s comments has prevented a more in-depth analysis of users’ thoughts and opinions.

Practical implications

The research findings may direct entrepreneurs, managers and policy makers to understand the variables to be leveraged and the actions to be taken to take advantage of the potential benefits that carpooling offers.

Originality/value

The work has utilized skills from three different areas, i.e., business management, computing science and statistics, which have been synergistically integrated for customizing, implementing and using two IT tools capable of automatically identifying, selecting, collecting, categorizing and analyzing people’s tweets about carpooling.

Abstract

Purpose

Young people transitioning from child to adult mental health services are frequently also known to social services, but the role of such services in this study and their interplay with mental healthcare system lacks evidence in the European panorama. This study aims to gather information on the characteristics and the involvement of social services supporting young people approaching transition.

Design/methodology/approach

A survey of 16 European Union countries was conducted. Country respondents, representing social services’ point of view, completed an ad hoc questionnaire. Information sought included details on social service availability and the characteristics of their interplay with mental health services.

Findings

Service availability ranges from a low of 3/100,000 social workers working with young people of transition age in Spain to a high 500/100,000 social workers in Poland, with heterogeneous involvement in youth health care. Community-based residential facilities and services for youth under custodial measures were the most commonly type of social service involved. In 80% of the surveyed countries, youth protection from abuse/neglect is overall regulated by national protocols or written agreements between mental health and social services, with the exception of Czech Republic and Greece, where poor or no protocols apply. Lack of connection between child and adult mental health services has been identified as the major obstacles to transition (93.8%), together with insufficient involvement of stakeholders throughout the process.

Research limitations/implications

Marked heterogeneity across countries may suggest weaknesses in youth mental health policy-making at the European level. Greater inclusion of relevant stakeholders is needed to inform the development and implementation of person-centered health-care models. Disconnection between child and adult mental health services is widely recognized in the social services arena as the major barrier faced by young service users in transition; this “outside” perspective provides further support for an urgent re-configuration of services and the need to address unaligned working practices and service cultures.

Originality/value

This is the first survey gathering information on social service provision at the time of mental health services transition at a European level; its findings may help to inform services to offer a better coordinated social health care for young people with mental health disorders.

Abstract

Purpose

The limit elastic speed of rotating disk is an important design criterion, as it defines the limit before onset of yielding initiates. The purpose of this paper is to establish the limit elastic speeds for S-FG disks and report the stresses induced at such speeds.

Design/methodology/approach

For S-FGM disk, effective Young’s modulus is calculated using modified rule of mixture and subsequently effective yield stress is also calculated by taking into consideration of stress-strain transfer ratio. The S-FGM disk is subject to centrifugal loading and the stress and deformation characteristics are investigated using variational principle wherein the solution is obtained by Galerkin’s error minimization principle. Based on von-Mises yield criteria, equivalent stress is calculated at different angular speeds till the equivalent stress at any given location in the disk attains the value of effective yield stress at the given location (location of yield initiation). This defines the limit elastic speed for the S-FGM disk (for given n).

Findings

The limit elastic speed of S-FGM disks for a range of grading index (n) and corresponding stresses within the disk are reported. Results are reported for uniform disks of different aspect ratio and the results reported could be used as practical design data.

Practical implications

Functional grading of material in structures opens a new horizon to explore the possibility of manufacturing high strength component at low weight. Material grading plays a significant role in achieving desired material properties, and literature review reveals reporting of numerous grading functions to approximate material distribution in structure.

Originality/value

The work has not been addressed earlier and findings provide a pioneering insight into the performance of S-FG disks.
