Abstract

Purpose

Musculoskeletal conditions are a major health concern in the USA because of a large aging population and increased occurrence of sport‐related injuries. Bone tissue engineering may offer a less painful alternative to traditional bone grafts with lower risk of infection. The purpose of this paper is to present a novel porogen‐based fabrication system for tissue engineering scaffolds using sucrose (C12H22O11) as the porogen building material.

Design/methodology/approach

A new solid freeform fabrication system has been developed and tested, which uses pressurized extrusion to print highly biocompatible and water soluble sucrose bone scaffold porogens (or negtives). Polycaprolactone (PCL) scaffolds are manufactured by injecting molten polymer into the porogens, and the porogens are subsequently dissolved with water. The resultant scaffolds demonstrate the defined porous structure designed into the sucrose porogen manufacturing computer‐aided design model.

Findings

To optimize the porogen manufacturing process, the viscosity of sucrose mixtures is measured. Design of experiments is used to plan and analyze the relationships between the porogen characteristics and the process parameters. Reservoir pressure and print head speed are identified as the dominant factors affecting sucrose flow rate and porogen strut diameter, respectively. The biocompatibility of the new system is assessed by in vitro cell culture testing. Endothelial hybridoma cells (EAhy 926) and osteoblasts (7F2) seeded on the fabricated PCL scaffolds adhered to the scaffold and proliferated over four to six days. Epifluorescence and scanning electron microscopy images reveal cell spreading and multiple layers of cells on the scaffold surface. The results demonstrated the potential of the structured sucrose porogen‐based fabrication method in manufacturing bone tissue scaffolds.

Originality/value

This paper describes the first time use of biomaterials‐sucrose to make scaffold porogens and how an injection molded biopolymer scaffold can then be received.

Abstract

Purpose

Religious pursuits may promote explicitly “spiritual” goods (theo-relational connectedness, character formation, etc.) and “secular” utilities including health. The purpose of this paper is to initiate investigation of this intersection for paternal religious practices in Lithuania’s dynamic post-Soviet social context. Reflecting on religio-political history, the nature of the religious field, spiritual capital, and externalities related to confessional identity, what relationships exist between institutional engagement, devotional practice, education and other predictors in the post-Soviet Lithuanian religious context?

Design/methodology/approach

Original data were collected in 2011 (returning 73 of 100 surveys) in Klaipėda, Lithuania. Correlation and χ2 identified variables for regression analysis. Given Ordinary Least Squares heteroscedasticity (Breusch-Pagan test), weighted least squares modeling estimated coefficients for extra mural and institutional religious practice generically and differentiated by confessional identity.

Findings

Generically and by confessional identity, utility differences in institutional context appear paradoxical to secularization hypotheses. While correlated, institutional engagement and non-institutional devotional practice evidenced non-complementarity regarding educational attainment: greater education predicted higher institutional engagement but sparer devotional life. The authors suggest in explanation higher opportunity costs in individual devotional practice opposite positive offsets from secondary institutional utilities (e.g. social networking). Both were predicted by education, work hours, the non-dependent religious practice variable, self-reported health status, patterned by confessional identity, specifically Protestant opposite majority Catholic. Intergenerationally, a gender gradient was identified.

Originality/value

This analysis illuminates with original data divergent public institutional and private devotional religious practice utility structures in a dynamic transitional post-Soviet context.

Abstract

Purpose

The purpose of this study is threefold: firstly, to compare Pakistani and French consumers’ perceptions of well-being; secondly, to investigate how consumers in both countries relate to food; and thirdly, to assess whether they associate food with well-being.

Design/methodology/approach

Thirty participants (15 French and 15 Pakistani) between the ages of 24 and 35 were interviewed, using convenience and snow bowling sampling. Data triangulation was performed by combining three qualitative techniques, word association, photo-elicitation-based interviewing and open-ended questions to explore consumer perceptions of well-being, food and food well-being.

Findings

The study’s findings suggest that well-being is a broad concept in which food is an ingredient. Food and well-being share common elements, and food well-being can be defined as an individual’s psychological, physical, social and societal relationship with food ascribed by affordability and food literacy.

Originality/value

Pleasure, sharing and respect emerged as dimensions of food well-being that can be applied to transfigure consumer behaviour and reduce over-consumption, food waste and hunger. The dimensions of well-being and food were explored for both countries to understand their cultural nuances and determine the influence of food on well-being. This comparative analysis will help researchers understand consumers’ preferences for food in various aspects from two regions. This study can potentially contribute to scale development in food and well-being, which can help researchers measure the effects of food and well-being in different sectors of the economy, particularly in health care. The most aspiring aspect of the current research is the insights unveiled during interactions with research participants, which will help develop consumer baseline feelings.

Abstract

Purpose

Social media experience a rapid rise in recent years and steep into almost every aspect of people's lives by altering their lifestyles and creating an impact on their wellbeing. The purpose of the present study is to examine the influence of SNSs on life satisfaction among university students by first exploring what are the key gratifications which motivates them to engage in SNSs and then focusing on the psychological outcomes including social overload and social benefit from using SNSs that affects life satisfaction among the university students.

Design/methodology/approach

Theory of social influence and uses and gratifications theory were used in this study to examine the motivations for using SNSs, and the impact of psychological outcomes associated with SNSs usage, i.e. social benefit and social overload on life satisfaction among university students of Pakistan. Partial least squares-structural equation modeling is used to analyze the data.

Findings

The outcomes indicate that the need for maintaining interpersonal interconnectivity, entertainment value and social enhancement value derives the students' participation in social networking sites through which they encounter social benefit and social overload. The presence of social benefit enhances life satisfaction while social overload results in decreasing life satisfaction of students. Using social networking sites influences life satisfaction in the presence of social overload and social benefit while there is no direct influence of social networking sites on life satisfaction was evidenced.

Research limitations/implications

The present study investigated the needs that drive the use of social media through the lens of UGT & Social influence approach. The other potential determinants of social media usage intention should be analyzed by employing variables of the other models.In this study social media was examined as a general platform used by the university students of Pakistan. In future researches the driving needs should be examined in the context of specific social networking sites.

Practical implications

The presented findings embraces the implications for the authorities of higher education institutions and policy makers as it provides the useful insights about student 2019s motivations and participation behavior in SNSs which would help in developing strategies for desirable results.

Social implications

Educational institutions can utilize the research findings by incorporating social media tools in the academic system, student's interaction with their mentors will lead towards enhanced involvement of students and intellectual skills along with upgraded academic performance which will positively influence life satisfaction of the students.

Originality/value

The scarcity of findings was observed in the local environment specifically in the context of SNSs usage and well-being of the higher education students. This study addresses the motivational factors of SNSs usage and their psychological outcomes simultaneously and focused on the investigation of social media usage drivers and its outcomes among the university students of Pakistan.

Abstract

Purpose

This paper highlights an assignment in a combination upper-division undergraduate and graduate civic leadership class at a Midwestern state comprehensive university. The three-part assignment challenges students’ critical thinking skills and research capabilities while simultaneously necessitating the exploration of contrasting viewpoints on contentious issues.

Design/methodology/approach

Intentionally exposing students to diverse perspectives in a controlled environment.

Findings

We posit that the severity and frequency of these issues can be mitigated through focused efforts.

Originality/value

Students are better prepared to engage in civil debate on controversial topics, which continuously divide our communities, after completing a class using this pedagogical strategy.

Abstract

Purpose

Through activism, brands participate in the sociopolitical controversies that shape society today. Based on social identity theory, this study aims to examine the moderating effects of consumer–brand identification (CBI) and political ideology in explaining consumer responses to brand activism. Furthermore, the role of perceived marginalization that can arise in the case of consumer–brand disagreement is explored.

Design/methodology/approach

The hypothesized effects were tested in three experiments. Study 1 (n = 262) and Study 2 (n = 322) used a moderation analysis, which was supplemented by a mixed design analysis with repeated measures in Study 1. In Study 3 (n = 383), the mediating effect of perceived marginalization by the brand was tested using a moderated mediation model.

Findings

The results show that strong CBI as well as a conservative ideology buffer the negative effects of consumer–brand disagreement on brand attitude and word-of-mouth intentions. In the case of agreement with a brand’s stance, no direct or interactive effects of brand activism on consumer responses occur. Perceived marginalization by a brand mediates the effects of brand activism.

Originality/value

This study extends the “love is blind” versus “love becomes hate” debate to the realm of brand activism and finds evidence for the former effect. It also contributes to the research on political consumption by highlighting the role of political ideology as an important boundary condition for brand activism. Perceived marginalization is identified as a relevant risk for activist brands.

Abstract

Purpose

This article describes the development processes, sampling and analysis practices and the assessment of reliability and validity of a new 0survey that sought to evaluate undergraduate students' perceptions and expectations related to privacy and library participation in learning analytics studies. This article provides other researchers with information required to independently evaluate the survey's efficacy, as well as guidance for designing other surveys.

Design/methodology/approach

Following question development, pre-survey validity assessments were made using subject matter expert panel review and cognitive interviews. Post-hoc analysis of survey construct reliability was evaluated using the Omega coefficient, while exploratory factor analysis was utilized to assess construct validity. Survey design limitations and potential bias effects are also examined.

Findings

The survey exhibited a high level of reliability among research constructs, while the exploratory factor analysis results suggested that survey constructs contained multiple conceptual elements that should be measured separately for more nuanced analysis.

Practical implications

This article provides a model for other researchers wishing to re-use the survey described or develop similar surveys.

Social implications

As learning analytics interest continues to expand, engaging with the subjects, in this case students, of analysis is critical. Researchers need to ensure that captured measurements are appropriately valid in order to accurately represent the findings.

Originality/value

This survey is one of very few addressing library learning analytics that has undergone extensive validity analysis of the conceptual constructs.
