Abstract
This paper gives a review of the finite element techniques (FE) applied in the area of material processing. The latest trends in metal forming, non‐metal forming and powder metallurgy are briefly discussed. The range of applications of finite elements on the subjects is extremely wide and cannot be presented in a single paper; therefore the aim of the paper is to give FE users only an encyclopaedic view of the different possibilities that exist today in the various fields mentioned above. An appendix included at the end of the paper presents a bibliography on finite element applications in material processing for the last five years, and more than 1100 references are listed.

Abstract
An implicit type algorithm for the integration of hypoelastic constitutive equations is proposed for large strain and large rotation conditions. Constitutive relations are derived in a deformation‐neutralized form. This provides the basis for integration in time resulting in an incremental tensor relation. Proposed algorithm can be considered as a generalization of the closest‐point‐projection method in the sense that the projection property applies to a ‘midstep’ rather than the final stress state. Hill's yield criterion under plane stress conditions suitable for metal‐forming applications is used in presented benchmark problems. Numerical results are discussed illustrating the accuracy of the algorithm for different values of the midstep parameter.

Abstract
Purpose
To provide a selective bibliography for researchers working with bulk material forming (specifically the forging, rolling, extrusion and drawing processes) with sources which can help them to be up‐to‐date.
Design/methodology/approach
A range of published (1996‐2005) works, which aims to provide theoretical as well as practical information on the material processing namely bulk material forming. Bulk deformation processes used in practice change the shape of the workpiece by plastic deformations under forces applied by tools and dies.
Findings
Provides information about each source, indicating what can be found there. Listed references contain journal papers, conference proceedings and theses/dissertations on the subject.
Research limitations/implications
It is an exhaustive list of papers (1,693 references are listed) but some papers may be omitted. The emphasis is to present papers written in English language. Sheet material forming processes are not included.
Practical implications
A very useful source of information for theoretical and practical researchers in computational material forming as well as in academia or for those who have recently obtained a position in this field.
Originality/value
There are not many bibliographies published in this field of engineering. This paper offers help to experts and individuals interested in computational analyses and simulations of material forming processes.

Abstract
This study compares perceptions regarding Indian versus American print advertisements of Asian‐Indian immigrants residing in the United States of America. It examines whether these perceptions varied with their degree of acculturation. Our results show that when Asian‐Indian immigrants are treated as a homogeneous group without considering their degree of acculturation, the preferences for Indian versus American advertisements are mixed. However, when examined from an acculturative perspective, we find that as acculturation increased, subjects preferred American advertisements more, and Indian advertisements less. The results imply that degree of acculturation should be considered as a segmentation variable when developing an advertising strategy for immigrant consumers.

This paper aims to find the effects of mothers’ schooling on child schooling.
Abstract
Purpose
This paper aims to find the effects of mothers’ schooling on child schooling.
Design/methodology/approach
This paper uses Bangladesh's Household Income and Expenditure Survey (HIES), which is a nationally representative survey. It employs the instrumental variable technique to estimate the intergenerational model.
Findings
Interestingly, the results show that the intergenerational transmission of schooling from mothers is slightly higher than that of fathers in Bangladesh.
Research limitations/implications
Estimating the intergenerational model is challenging due to the endogeneity issue. The methodology used in this paper may help to find similar evidence from other countries.
Practical implications
The findings of the study may help to design and evaluate the educational policies in Bangladesh or a country like Bangladesh. For instance, the results of this paper suggest that the female stipend program (FSP) in Bangladesh is effective for the next generation’s schooling.
Originality/value
This paper is among the first to analyze the effect of mother’s schooling on the child’s schooling, controlling the father’s education and other household characteristics. In addition, it controls for endogeneity bias due to genetic transmission.

Abstract
Some frictional contact problems are characterized by significant variations in the location and size of the contact area occurring in the process of deformation. When this feature is combined with strongly non‐linear, path‐dependent material behaviour, difficulties with convergence of the typically used iterative processes can be encountered. Demonstrates this by analysis of press‐fit connection, a typical problem in which both of those characteristics can be present. Offers an explanation as to the possible source of those difficulties. Suggests in support of this explanation, two simple modifications of the usual iterative schemes. In spite of their simplicity, they are found to be more robust than those usual schemes which are normally used in numerical analysis of similar problems.

Abstract
Purpose
The purpose of this paper is to find the effects of human capital inequality on economic growth.
Design/methodology/approach
Thailand Labor Force Survey has been used to generate provincial average years of schooling and Gini coefficient of years of schooling for the years 1995‒2012. Econometric techniques have been employed to identify the effects of human capital inequality on economic growth.
Findings
Economic growth is inversely affected by the distribution of human capital in Thailand. The coefficient of human capital inequality suggests that if Gini coefficient increases by 0.01 points, gross provincial product (GPP) decreases by about 2 percentage points in the long run. However, the effect of average years of schooling in GPP is not significant.
Research limitations/implications
There is a lack of strong theoretical background for the relationship between human capital inequality and economic growth to support the empirical study.
Practical implications
The findings of the study help to design and evaluate education policies in developing countries like Thailand and other low- and middle-income countries.
Originality/value
This paper is among the first attempts to analyze the effect of human capital inequality on economic growth with sub-national level annual data. In addition, it considers cross sectional dependence in panel model.

Abstract
Purpose
This article aims to develop a measurement scale for assessing agripreneurial competencies relevant to emerging economies in alignment with the SDG2 of the UN Sustainable Development Goals 2030.
Design/methodology/approach
The scale development procedure includes item development and refinement, data collection, reliability and validity tests and scale purification with exploratory factor analysis (EFA) and confirmatory factor analysis (CFA).
Findings
The validated scale carries eight dimensions of competencies: Agreeableness (AG), Technological Competency (TC), Competitive Spirit (CS), Innovativeness (IN), Self-Confidence (SC), Social Responsibility (SR), Conscientiousness (CO) and Leadership (LS). The analysis puts forth a good and fit model, and the new scale reports sufficient convergent and discriminant validity.
Research limitations/implications
This study is focused on the agripreneurial competencies of individual agripreneurs; institutional agripreneurs are excluded from the study.
Social implications
Identifying prominent agripreneurs using the scale developed from this study will aid in allocating various government and non-governmental organisations' assistance to agripreneurs. Since developing economies rely heavily on agriculture, any positive contribution can help alleviate poor economic growth, end hunger, and promote sustainable agriculture (SDG 2 of 2030).
Originality/value
Though several scales for measuring entrepreneurial competencies are available, there is no standard scale to measure agripreneurial competencies. This article presents the development and validation of a measurement scale to assess the major competencies of agripreneurs that influence agripreneurship performance.

Abstract
Purpose
The purpose of this paper is to shed light on the interplay between selected consumer behavior constructs and their individual and joint influences on purchase intentions of global, local, and hybrid brands. This is a topic that is becoming increasingly important as the world moves toward global economic interdependence and increasingly more firms expand abroad.
Methodology/findings
As the paper is in its conceptual/modeling phase, its research design is not yet complete, nor does it offer any findings. Resting our work on attitude and identity theories, we derive hypotheses about the potential influence of consumer behavior constructs, that is, the levels of the consumer’s global consumption orientation, globalization attitude, consumer ethnocentrism, and consumer cosmopolitanism on global brand attitude and its influence on willingness to purchase global versus nonglobal brands. We also derive hypotheses about influences that might moderate this relationship; specifically the consumer’s affinity with the home country of the particular brand, and the perceived value embedded in the brand.
Research/practical/social implications
Our work will contribute to the expanding literature on global consumer culture and consumption patterns and will thus provide valuable insights for international marketing managers and for social policy.
Originality/value
Our work will examine the joint influences of several consumer behavior constructs on brand purchase behavior, in addition to the independent influences of these constructs. It will also explore the possible mediating influence of global brand attitude on purchase intentions and moderating effects, if any, of perceived value and consumer affinity on consumers’ choices of global over local and hybrid brands.
