Abstract

Purpose

The purpose of this paper is to study the operation performance of the high-speed ramjet kinetic energy projectile using solid fuel ramjet as power plant that is a new short-range and small caliber projectile.

Design/methodology/approach

The numerical investigation on combustion characteristic of polyethylene in high-speed ramjet kinetic energy projectile is carried out in this paper. The flow characteristics’ differences are analyzed when ramjet works or do not work, and both the combustion characteristics and propulsive performance are analyzed when ramjet works.

Findings

The results show that with the increase of the abscissa x, the flame front is close to solid fuel surface at first and then keeps away from solid fuel surface. With the increase of the abscissa x, the temperature of solid fuel surface and regression rate of solid fuel continues to increase before re-attachment point and then decreases, which a maximum locate at the re-attachment point. Both the average temperature and the regression rate on the surface of the solid fuel tend to rise as the increase of inflow Mach number. As the inflow of Mach number increases, the mass flow rate of gaseous fuel increases.

Practical implications

The research results can provide useful database for the subsequent research on high-speed ramjet kinetic energy projectile.

Originality/value

This paper studies the operation characteristics of the ramjet projectile, especially the effect of the change of the flight velocity on the performance of high-speed ramjet projectile.

Abstract

Purpose

The purpose of this paper is to study the resource construction mode of the Digital Library Promotion Project, so as to summarize the general characteristics of successful collaborative collection building for digital libraries. Digital Library Promotion Project (DLPP) is a digital culture boosting project launched by the Ministry of Culture of the People’s Republic of China with National Library of China as its implementing unit. The project aims to build a nation-wide library network that could support and guarantee resource development and sharing among public libraries all over China so as to achieve equalization in public culture service among people from different parts of the country. This paper is a case study of the digital library development in China. The present situation of Chinese public libraries is accounted in this paper, and the developing mode and mechanism in cooperation between libraries of different administrative ranking are discussed along with the future development of the project. This paper may provide references to countries and libraries in their efforts to pursue sustainable development.

Design/methodology/approach

This paper is a case study of digital collection development and sharing in a developing country where regional differences are large. The paper starts with the environmental scan of the resource situation of public libraries in China, which is the background and significance of the DLPP. The main part of the paper is the introduction and analysis of the collection developing method of the DLPP, including: union catalogue, co-construction of featured resources and joint procurement of databases. Through analyzing the mechanism in collection development and sharing, this paper discusses the measures that guarantees the success of the project.

Findings

Through analyzing the mechanism in collection development and sharing, this paper discusses the measures that guarantee the success of the project, these are: sustained financial support from the government, scientific mechanism for cooperation, flexible handling of copyright issues unified standards in resource development and targeted training programs.

Originality/value

This paper is a case study of the digital library development in China. The present situation of Chinese public libraries is accounted in this paper, and the developing mode and mechanism in cooperation between libraries of different administrative ranking are discussed, as well as the future development of the project. This paper may provide references to countries and libraries in their efforts to pursue sustainable development.

Abstract

Purpose

The purpose of this paper is to develop a conceptual framework which deepens our understanding of identity negotiation and formation in a collectivistic Asian context. Drawing from a three-year, multi-method ethnographic research process, the authors explore how contemporary Asian consumers construct, negotiate and enact family identity through meal consumption. The authors particularly focus on the ways in which Asian consumers negotiate values, norms and practices associated with filial piety during new family formation. Building on the influential framework of layered family identity proposed by Epp and Price (2008), the authors seek to develop a framework which enables us to better understand how Asian consumers construct and enact their family identity through mundane consumption.

Design/methodology/approach

As most of the identity negotiation in the domestic sphere takes place within the mundanity of everyday life, such as during the routines, rituals and conventions of “ordinary” family meals, the authors adopted an interpretive, hermeneutic and longitudinal ethnographic research approach, which drew from a purposive sample of nine Sri Lankan couples.

Findings

The authors present the finding in three vivid narrative exemplars of new family identity negotiation and discuss three processes which informants negotiated the layered family identity. First, Asian families negotiate family identity by re-formulating aspects of their relational identity bundles. Second, re-negotiating facets of individual identity facilitates construction of family identity. Finally, re-configuring aspects of collective family identity, especially in relation to the extended family is important to family identity in this research context. The authors also propose filial piety as a fundamental construct of Asian family identity and highlight the importance of collective layer over individual and relational family identity layers.

Research limitations/implications

The aim of this paper is to develop a conceptual framework which deepens our understanding of identity negotiation and formation in a collectivistic Asian context. Even though exploring Sinhalese, Sri Lankan culture sheds light on understanding identity and consumption in other similar Asian cultures, such as Indian, Chinese and Korean; this paper does not suggest generalisability of findings to similar research contexts. On the contrary, the findings aim to present an in-depth discussion of how identities are challenged, negotiated and re-formulated during new family formation around specific consumption behaviours associated with filial piety in a collectivistic extended family.

Social implications

As this research explores tightly knit relationships in extended families and how these families negotiate values, norms and practices associated with filial piety, it enables us to understand the complex ways in which Asian families negotiate identity. The proposed framework could be useful to explore how changing social dynamics challenge the traditional sense of family in these collectivistic cultures and how they affect family happiness and well-being. Such insight is useful for public policymakers and social marketers when addressing family dissatisfaction–based social issues in Asia, such as increasing rates of suicide, divorce, child abuse, prostitution and sexually transmitted disease.

Originality/value

Little is known about the complex ways in which Asian family identities are negotiated in contrast to Western theoretical models on this topic. Particularly, we need to understand how fundamental aspects of Asian family identity, such as filial piety, are continuously re-negotiated, manifested and perpetuated during everyday life and how formulations of Asian family identity may be different from its predominantly Western conceptualisations. Therefore, the paper provides an adaptation to the current layered family identity model and proposes filial piety as a fundamental construct driving Asian family identity.
