Abstract

Purpose

To obtain a vascularized autologous bone graft by in-vivo tissue transformation, a biocompatible tissue transformation mold (TTM) is needed. An ideal TTM is of high geometric accuracy and X-ray radiolucent for monitoring the bone tissue formation. The purpose of this study is to present the TTM design and fabrication process, using 3D reconstruction, stereolithography (SLA) and silicone molding.

Design/methodology/approach

The rat mandible, the targeted bone graft, was scanned by micro-computed tomography (CT). From the micro-CT images, the 3D mandible model was identified and used as the cavity geometry to design the TTM. The TTM was fabricated by molding the biocompatible and radiolucent silicone in the SLA molds. This TTM was implanted in a rat for in vivo tests on its biocompatibility and X-ray radiolucency.

Findings

SLA can fabricate the TTM with a cavity shape that accurately replicates that of the rat mandible. The bone formation inside of the silicone TTM can be observed by X-ray. The TTM is feasible for in vivo tissue transformation for vascularized bone reconstruction.

Research limitations/implications

Research of the dimensional and geometrical accuracy of the TTM cavity is required in the future study of this process.

Practical implications

The TTM fabricated in this presented approach has been used for in-vivo tissue transformation. This technique can be implemented for bone reconstruction.

Originality/value

The precision fabrication of the TTMs for in-vivo tissue transformation into autogenous vascularized bone grafts with complex structures was achieved by using SLA, micro-CT and silicone molding.

Abstract

This paper explores the relationship between feminist theory and rising economic inequality. It shows how greater inequality reflects the valorization of the stereotypically male qualities of competition and hierarchy, producing a greater concentration of wealth among a small number of men at the top, shortchanging men more than women through the rest of the economy, and altering the way that men and women match up to each other in the creation of families. By creating a framework for further research on the relationship between the norms of the top and the disadvantages of everyone else in more unequal societies, the paper provides a basis for feminists to develop a new theory of social power.

The paper demonstrates how the development of winner-take-all income hierarchies, the political devaluation of families and communities, and the terms of the family values debate diminish equality and community. The paper addresses how to understand these developments as they affect both the structure of society and the allocation of power within our families in ways that link to the historic concerns of feminist theory. It accordingly ends by asking the “woman question” in a new way: one that revisits the stereotypically masculine and feminine and asks how they connect to hierarchy, one that considers whether the inclusion of women changes institutional cultures in predictable ways, and one that wonders whether the values that today are associated with more women than men offer a basis for the reconstruction of society more generally.

Abstract

This chapter sheds light on long-term trends in the level and structural dynamics of investments in Russian human capital formation from government, corporations, and households. It contributes to the literature discussing theoretical issues and empirical patterns of modernization, human development, as well as the transition from a centralized to a market economy. The empirical evidence is based on extensive utilization of the dataset introduced in Didenko, Földvári, and Van Leeuwen (2013). Our findings provide support for the view expressed in Gerschenkron (1962) that in late industrializers the government tended to substitute for the lack of capital and infrastructure by direct interventions. At least from the late nineteenth century the central government's and local authorities' budgets played the primary role. However, the role of nongovernment sources increased significantly since the mid-1950s, i.e., after the crucial breakthrough to an industrial society had been made. During the transition to a market economy in the 1990s and 2000s the level of government contributions decreased somewhat in education, and more significantly in research and development, but its share in overall financing expanded. In education corporate funds were largely replaced by those from households. In health care, Russia is characterized by an increasing share of out-of-pocket payments of households and slow development of organized forms of nonstate financing. These trends reinforce obstacles to Russia's future transition, as regards institutional change toward a more significant and sound role of the corporate sector in such branches as R&D, health care, and, to a lesser extent, education.

Abstract

Purpose

The purpose of this paper is to examine the behaviors and social interactions among preschool children and their teachers during food consumption at a daycare facility. Using social cognitive theory, the goal is to identify how role modeling, rules, behaviors and communication shape these young consumers’ health-related food consumption and habits.

Design/methodology/approach

This study was conducted in a US daycare facility among preschool children (aged four years) over a three-month period. Qualitative ethnographic methods included participant and non-participant observation of meals and snack-time.

Findings

Findings from the observations revealed that teachers’ food socialization styles and social interactions with peers cultivate children’s food consumption. In addition, commensality rules set by the childcare institution also help children learn other valuable behaviors (e.g. table manners and cleaning up).

Research limitations/implications

The study was conducted in one location with one age group so the results may not be generalized to all children. As more young children spend time in preschools and daycare centers, the understanding of how these settings and the caregivers and peers influence them becomes more important. Preschool teachers can influence their young students’ food consumption through their actions and words. Training teachers and cultivating educational programs about ways to encourage healthy eating habits could be implemented.

Originality/value

The paper offers observations of actual behaviors among young children in a naturalistic setting.

Abstract

Purpose

This paper aims to highlight the role of mindfulness in the development of indigenous knowledge (IK), indigenous innovations and entrepreneurship or new entry.

Design/methodology/approach

Through an extensive analysis of extant mindfulness and indigenous entrepreneurship literatures, the paper argues for the facilitating role of individual mindfulness in IK, indigenous innovations and entrepreneurship and generates several propositions as a result.

Findings

The paper argues that mindfulness encourages the appreciation of other forms of knowledge and practices distinct from the more prevalent Western forms, and by so doing, promotes indigenous innovation and indigenous entrepreneurship (or indigenous new entry or new business venture).

Research limitations/implications

It is reasoned that indigenous communities around the world have rich experiences and accumulated knowledge that have enabled them develop explanations of their environments and economic development and sustainability, and by recognizing and valuing such knowledge and experiences, mindfulness facilitates innovations and entrepreneurship.

Social implications

The facilitating role of IK in developing indigenous innovations and indigenous entrepreneurship is clearly evident, at least in indigenous societies; however, researchers are yet to recognise and explore this dynamics as deserved. Mindfulness not only opens up the mindset of researchers to further explore this phenomenon but also helps society to recognise the contributions and value of IK.

Originality/value

This work is a pioneer in the effort to integrate mindfulness concept into the indigenous entrepreneurship research. By using mindfulness lens to view the relationship between IK, indigenous innovations and entrepreneurship, the study locates mindfulness as both antecedent to and moderator of these relationships.

Abstract

Purpose – Are members of socially dominant groups aware of the privileges they enjoy? We address this question by applying the notion of hypocognition to social privilege. Hypocognition is defined as lacking a rich cognitive or linguistic representation (i.e., a schema) of a concept in question. By social privilege, we refer to advantages that members of dominant social groups enjoy because of their group membership. We argue that such group members are hypocognitive of the privilege they enjoy. They have little cognitive representation of it. As a consequence, their social advantage is invisible to them.

Approach – We provide a narrative review of recent empirical work demonstrating and explaining this lack of expertise and knowledge in socially dominant groups (e.g., White People, men) about discrimination and disadvantage encountered by other groups (e.g., Black People, Asian Americans, women), relative what members of those other groups know.

Findings – This lack of expertise or knowledge is revealed by classic cognitive psychological measures. Relative to members of other groups, social dominant group members generate fewer examples of discrimination that other groups confront, remember fewer instances after being presented a list of them, and are slower to respond when classifying whether these examples are discriminatory.

Social Implications – These classic measures of cognitive expertise about social privilege predict social attitude differences between social groups, specifically whether people perceive the existence of social privilege as well as believe discrimination still exists in contemporary society. Hypocognition of social privilege also carries implications for informal interventions (e.g., acting “colorblind”) that are popularly discussed.
