This study aimed to compare the performance of sustainable shoes made with bacterial cellulosic composite and commercial leather shoes using an experimental research design. The two specific research objectives were: (1) to examine the basic material properties of multi-layered bacterial cellulosic materials (MBC), which include green tea-based cellulosic (GBC) mats, hemp fabrics, and denim fabrics, in comparison with those of two-layered leathers (MCP) consisting of calf-skin and pig-skin – commonly used in shoe manufacturing; and (2) to explore wearers’ performance in the two types of shoes by assessing quantitative kinematic and kinetic parameters of lower body movements.

This study focused on assessing the basic materials testing and performance of sustainable shoes through a biomechanical approach, in contrast to commercially available leather shoes, through human wear trials. In this study, green tea-based cellulosic (GBC) mats were developed using the optimal combination of ingredients for cellulose growth. Subsequently, the GBC, denim fabric (100% cotton), and 100% hemp fabric were combined to create multi-layered bacterial cellulosic materials (MBC) as an alternative to leather. Additionally, calf-skin and pig-skin leathers were utilized to produce a commercially available two-layered leather (MCP), commonly employed in shoe manufacturing. 37 of the 42 human subjects who participated in wear testing were collected. A paired t-test was conducted to determine whether significant mean differences existed between the two shoe types, a paired t-test was conducted.

To develop a biodegradable and compostable material that could be used as a leather alternative for the footwear industry, we proposed MBC and examined its properties compared with those of MCP, a product often used when making shoes. These findings confirmed the similar properties of MBC and MCP from the material testing and the possibility of using a men’s sustainable shoe prototype as a leather alternative, in terms of kinematics and kinetics.

The new multi-layered bacterial cellulosic materials (MBC) could be an alternative to commercial leathers such as innovative sustainable material construction, advanced design, and advanced techniques to optimize the overall performance of sustainable footwear.

Investigating the integration of smart textile technologies, ergonomic design principles, and personalized customization will contribute to developing MBC and making sustainable shoes using MBC compared with commercial leather shoes. This study provides valuable insights into further refinement and innovation in the sustainable footwear industry.

THE Reference Department of Paisley Central Library today occupies the room which was the original Public Library built in 1870 and opened to the public in April 1871. Since that date two extensions to the building have taken place. The first, in 1882, provided a separate room for both Reference and Lending libraries; the second, opened in 1938, provided a new Children's Department. Together with the original cost of the building, these extensions were entirely financed by Sir Peter Coats, James Coats of Auchendrane and Daniel Coats respectively. The people of Paisley indeed owe much to this one family, whose generosity was great. They not only provided the capital required but continued to donate many useful and often extremely valuable works of reference over the many years that followed. In 1975 Paisley Library was incorporated in the new Renfrew District library service.

Rooted in adult fear, adult authority aims to protect and control youth (Gannon, 2008; Valentine, 1997). Continuously negotiating for freedom, youth search for adult-free public spaces and are therefore extremely attracted to social networking sites (boyd, 2007, 2014). However, a significant portion of youth now includes adult authorities within their Facebook networks (Madden et al., 2013). Thus, this study explores how youth navigate familial- and educational-adult authorities across social networking sites in relation to their local peer culture.

Through semi-structured interviews, including youth-centered and participant-driven social media tours, 82 youth from the Northeast region of the United States of America (9–17 years of age; 43 females and 39 males) shared their lived experiences and perspectives about social media during the summer of 2013.

In their everyday lives, youth are subjected to the normative expectations emerging from peer culture, school, and family life. Within these different and at times conflicting normative schemas, youth’s social media use is subject to adult authority. In response, youth develop intricate ways to navigate adult authority across social networking sites.

Adult fear is powerful, but fragile to youth’s interpretation; networked publics are now regulated and youth’s ability to navigate then is based on their social location; and youth’s social media use must be contextualized to be holistically understood.

While qualitative work has a long tradition in the strategy field and has recently regained popularity, we have not paused to take stock of how such work offers contributions. We address this oversight with a review of qualitative studies of strategy published in five top-tier journals over an extended period of 15 years (2003–2017). In an attempt to organize the field, we develop an empirically grounded organizing framework. We identify 12 designs that are evident in the literature, or “designs-in-use” as we call them. Acknowledging important similarities and differences between the various approaches to qualitative strategy research (QSR), we group these designs into three “families” based on their philosophical orientation. We use these designs and families to identify trends in QSR. We then engage those trends to orient the future development of qualitative methods in the strategy field.

The overall goal of science is to build a valid and reliable body of knowledge about the functioning of the world and how applying that knowledge can change it. As personnel and human resources management researchers, we aim to contribute to the respective bodies of knowledge to provide both employers and employees with a workable foundation to help with those problems they are confronted with. However, what research on research has consistently demonstrated is that the scientific endeavor possesses existential issues including a substantial lack of (a) solid theory, (b) replicability, (c) reproducibility, (d) proper and generalizable samples, (e) sufficient quality control (i.e., peer review), (f) robust and trustworthy statistical results, (g) availability of research, and (h) sufficient practical implications. In this chapter, we first sing a song of sorrow regarding the current state of the social sciences in general and personnel and human resources management specifically. Then, we investigate potential grievances that might have led to it (i.e., questionable research practices, misplaced incentives), only to end with a verse of hope by outlining an avenue for betterment (i.e., open science and policy changes at multiple levels).

Multitiered systems of support (MTSS) is widely advocated as an approach to improving education for all students, including students with disabilities. A hope for MTSS is that it can solve or mitigate many problems associated with providing special education to students with disabilities. While MTSS shows some promise for better addressing these problems, enthusiasm for MTSS and unsound thinking about what MTSS can do, cannot do, and has not done can veil lack of progress toward improving special education, as well as obscure what improving special education requires. We suggest that for both MTSS and special education to make more progress toward achieving their promises, several reality checks are urgently needed.

There is much to justify the old “ saw ” that what is one man's food may be another man's poison. Even among healthy individuals this holds true; and it is explained by a peculiarity of constitution attaching to some individuals that may be termed, in non‐technical language, idiosyncrasy.

The power and usefulness of perceived risk theory in understanding shoppers’ behaviour has been demonstrated many times over recent years in the UK by the numerous food scares. The article explores how retailers use perceived risk in their strategies and develops the links between store attributes and risk dimensions. This re‐interpretation of previous store‐image studies provides a new conceptual framework for understanding store image and deepens our knowledge of how risk and risk‐reduction are operationalised in practice. The paper also reviews some evidence on factors which affect shoppers’ risk perceptions, e.g. age, gender, group discussion, brand name and shopping channel and discusses how the risk concept can be used by food retailers as well as presenting some ideas for future research.
