The main objectives of this research work were to investigate the effect of production speed on intermingled yarn properties and melange fabric properties with special reference to melange appearance.

Polyester/nylon intermingled yarns were produced using an SSM DP3-C air-intermingling machine using commercial process parameters and Heberlein P212 nozzle. Melange fabric samples were knitted from polyester/nylon intermingled yarns while maintaining the same parameters to avoid knitting variations. The fabric samples were dyed using a sample dyeing machine while maintaining dye recipe and dyeing parameters constant to avoid dyeing variations.

The production speed has significant effect on intermingled yarn and melange fabric properties. When the production speed is increased, mingle points, mingle stability, linear density, strength and the elongation of the intermingled yarns decreases. When the production speed is increased, fabric weight decreases and the melange effect varies from dot-like appearance to line-like appearance.

Only the effect of production speed on intermingled yarn and melange fabric properties is discussed in this paper. Appearance evaluating systems developed in this research are limited to melange fabrics produced using air-intermingled yarns with two colour components.

Results indicate that the intermingled yarns for the application of melange fabrics should be developed with optimum intermingling speeds, and it should not be changed during the production since production speed has significant effect on yarn and fabric parameters. Therefore, melange appearance and fabric weight may vary between fabric lots with different production speeds even though all the other parameters are kept constant. Further, melange appearance evaluation method developed in this research could be used as a guide in developing melange fabrics.

This research introduced a qualitative and a quantitative method to analyse melange fabric appearance. This melange appearance evaluation method can be used as a guide to achieve specific melange effect in the sample development stage. Further, when a melange sample appearance catalogue is developed for all the variables for a particular fabric type using this evaluation method, customer requested appearance can be achieved in minimum sample trials which save time, capacity, money and customer credibility.

The purpose of this paper is to review, analyze and synthesize different pieces from literature to explore, define and describe the concept of social capital and its relationships with urban neighborhood design concepts. Additionally, to define the indicators and principles that can enhance social capital within urban design context. Moreover, to suggest theoretical urban neighborhood design concept that can adopt the changing discourse of social capital.

This research used the theoretical, analytical and descriptive approach-driven case study method. In all, 29 papers were analyzed to conclude the indicators that can measure social capital within the urban neighborhood design context and to conclude the required neighborhood design features and principles that influence social capital. Additionally, two new urban neighborhoods design concepts, cohousing and hybrid concepts that adopt new forms of social interaction, were studied, analyzed and then synthesized to suggest new neighborhood design concept, which is a heterotopia concept.

Heterotopia neighborhood concept aims to create real, different and heterogeneous functional spaces with different layers of meanings for people from different cultures in one place. Different visible enclosures are merged into spaces of otherness while the diversity gives a sense of entering another alternative place. The heterotopias neighborhood design principles aim to create a wide variety of forms, shapes and elements [different new spaces for different ritual activities to reflect the otherness self-reflection (homogeneous and scattered spaces)] and create linkage, hierarchy, contrast and mingling between spaces and places; well-defined functional effective spaces; different fantasy and leisure spaces; high standard quality of life and otherness space; flux in social realm and fluidity of spaces; mixed use and joint experience; and innovated technologies spaces to offer strange new temporalities.

This research recommended that different community stakeholders should participate in planning process, neighborhood urban design and decision-making process about public spaces to strengthen the community ties and achieve a heterotopia concept. Architect, urban designers and planners should adopt bottom-up design approach when designing neighborhood. Additionally, to avoid poor social capital research studies, the new researchers, practitioners and journal reviewers approaching social capital for the first time must read widely to gain an understanding of the concept from different perspectives and narrow their scope to their particular area of interest.

This research highlights the needs for empirical studies to examine the relationships/interrelationships between all neighborhood design principles and social capital. This might increase the knowledge on how we can design and increase the quality of neighborhood to foster social capital, which might offer interesting insights into how neighborhood urban design principles are combined to foster social capital within neighborhood context.

Neighborhood-based research encourages new suggesting concepts in designing every single place in the residential neighborhood in a way that can adapt the new forms of social interaction. This research scanned the current concepts of neighborhood design that concerned successfully with the changing forms of social relationships to conclude some design features and principles for neighborhood design to ensure and promote social public health and well-being. This research offers a unique perspective for better understanding the relationships between the neighborhood urban design as a spatial dimension and social capital. This research aims to enrich the socio-spatial knowledge and build a resilient urban community by suggesting theoretical urban neighborhood design concept, which is the heterotopia concept, and providing the urban designers and architects with a valuable thinking tool to design spaces.

This paper focuses on social innovation dynamics in extreme contexts where institutional volatility is deeply rooted and enduring. In other words, the authors focus their discussion on the challenges that social innovators are facing in their endeavor of solving wicked social problems within an extreme institutional environment. This research is guided by the following question: How does an extreme institutional environment influence social innovation processes?

This qualitative research builds on the unique case of the Palestinian non-governmental organization (NGO) sector, a rarely studied context in organizational studies. The authors combine archival sources with 24 semi-structured interviews with Palestinian NGOs.

The authors theorize three barriers that hinder social innovation in such contexts: institutional trap, effectiveness trap and sustainability trap. The authors also theorize five mechanisms through which these barriers influence each other dynamically: mingling, surviving, undermining, binding and reinforcing. Taken together, these barriers and mechanisms shed light on social innovation processes taking place within extreme institutional environments.

The main limitation of this study is the methodological design, based on an extreme single case-study which, on a bunch of features, is quite unique in the world. The authors argue that the results are all the same transferable to other relatively similar contexts.

By theorizing the institutional barriers to social innovation in an extreme institutional context, the research thus sheds light on how social innovation could be sustained and stimulated in Palestine and other contexts that face similar institutional challenges.

From an engaged scholarship perspective, studying Palestine cannot be more relevant than today considering the turmoil in which Palestinians are. The research thus provides a deeper understanding of organizational and institutional dynamics with crucial social repercussions.

The social innovation literature has overemphasized success stories to the detriment of the struggles that hinder social innovations in extreme institutional environments. By focusing on the barriers that social innovators experience in these contexts, the authors provide novel empirical insight. Furthermore, this study enriches the understanding of the institutional dynamics of social innovations by proposing a process model that elucidates how an extreme institutional context can influence social innovations.

The distinction between formality and informality has been a topic central for many scholarly fields. Without rejecting the usefulness of this distinction, the authors argued that instead of analyzing an empirical situation in terms of what is formal and what is informal, it could sometimes be fruitful to focus on what is stable and what is fluid.

This paper reports the results of review and analysis of secondary sources on the distinction between formality and informality, followed by a conceptualization of an alternative distinction between fluidity and stability. This conceptualization was inspired by a science and technology studies (STS) understanding of relations, and was assessed through applying it to a case of patient organizations’ participation in patient councils in Russia.

Stability and fluidity do not map neatly into formality and informality; rather, the stability and fluidity cut across these categories. The authors propose a view of both stability and fluidity as kinds of relations between elements of the societal fabric. The distinction proposed here could be especially fruitful when applied to analyses of (1) complex bureaucracies where formal requirements are extensive and potentially in conflict with each other and (2) oppressive situations where significant power imbalances exist.

Instead of providing yet another line of demarcation between formality and informality, this paper proposes a shift in attention to what is stable and what is fluid. This novel distinction can help not only in discerning how things actually work but also in bringing to the fore hitherto unnoticed forms of creativity, responsiveness and inclusion.

Although extant post-acquisition literature has mainly focused on the integration of stand-alone firms, many acquisitions involve select units that were divested from former parents. Scholars have therefore recently called for moving beyond the dominant dyadic acquirer–target view of the acquisition process to a triadic view that considers the roles of, and interactions between, divestors, targets, and acquirers in the acquisition process. The authors set out to build an extended process view of such triadic relations based on a five-year longitudinal case study of one entrepreneurial company, acquiring two divested units from large multinational companies. The case sheds light on how divestors and acquirers together shape synergy realization efforts and identity-building by targets, causing dramatic shifts in perceptions of success throughout the acquisition process. The authors hope the case offers greater understanding, and triggers more research, into mingled integration and disintegration processes. The authors also highlight three impediments that can shape post-acquisition choices and discontinuous processes when acquiring divested units.

Purpose – This chapter first provides the motivation for writing this book. It then describes the challenges involved with assessing societal safety through the analysis of transport system crashes. It concludes with a summary of the contents of the remainder of the book, identifying how various dimensions of the transport system challenges are addressed.

Methodology/Approach – This chapter discusses important real-world and methodological challenges that practitioners, academics and researchers face in making a more sustainable highway system through a reduction in the number and severity of transport network crashes resulting in fatalities, injuries and property damage.

Findings – The chapter first describes important challenges, such as complexity of the driving task, the challenges of engineering transport systems for humans, unanticipated effects that arise from differences between driver safety and security, the co-mingling of mobility modes of travel, and challenges in evaluating road safety. The chapters are separated into five general themes: driver behaviour, the transportation network, vulnerable road users, methods for understanding and predicting safety performance, and methods for evaluating safety impacts of countermeasures.

Practical Implications – Comprehending the challenges associated with road crashes is a first step in making the roadway system more sustainable. This book provides a broad and understandable description of these challenges and how they can be overcome by academics and practitioners working in transport network safety management.

Originality – This book presents a clear understanding and offers insights about the challenges and potential solutions that can be brought to bear to make a more sustainable and safe transport system, whether it is located in an urban or rural area, and for a wide variety of functional classifications and designs. The topics covered in this book are intended to be useful and applied to tackle transport system management anywhere in the world.

The relationship between cultural novelty and cross-cultural adjustment of expatriates is often assumed to be negative and linear, while the empirical results for the relationship has been demonstrated by researchers as either negative, positive or absent.

The current research challenges the negative and linear assumption conceptually and empirically and tests a curvilinear relation between cultural novelty and general adjustment. The authors specifically propose and test a theoretical model whereby emotional stability moderates the curvilinear cultural novelty–general adjustment relationship such that the negative effect of cultural novelty on general adjustment is mitigated by emotional stability. Survey data are collected from expatriates recruited from two different host countries, India (N = 151) and China (N = 157).

The findings provide support for the curvilinear relationship between cultural novelty and general adjustment and the moderating effect of expatriates' emotional stability on this relationship.

This present study makes unique contributions to the expatriate management literature in at least two major ways: first, this study consolidates the otherwise contradictory findings and furthers the understanding on the nature of the effect of cultural novelty on expatriate adjustment. In addition, this research tests a cultural novelty–expatriate adjustment model using expatriate samples drawn from China and India, the two largest emerging markets that capture the demographic-profile changes pertaining to the newly emerging expatriation trends.

This study aims to investigate the morphology and physicochemical properties of BiOBr/Polyvinylidene fluoride (PVDF) composite membranes and the differences in the properties of BiOBr/PVDF composite membranes made by adding different precursor ratios during the casting process.

In this paper, sodium bromide and Bi(NO3)3 were used as precursors for the preparation of BiOBr photocatalysts, and PVDF membranes were modified by using the phase conversion method in conjunction with the in situ deposition method to produce BiOBr/PVDF hydrophilic composite membranes with both membrane separation and photocatalytic capabilities.

The characterization results confirmed that the composites were successfully and homogeneously co-mingled in the PVDF membranes. The related performance of the composite membrane was tested, and it was found that the composite membrane with the optimal precursor incorporation ratio had good photocatalytic efficiency and antipollution ability; the removal efficiencies of methyl orange, rhodamine B and methylene blue were 80.43%, 85.02% and 86.94%, respectively, in 2.5 h. The photocatalytic efficiency of composite membranes with different precursor ratios increased and then decreased with the increase of the precursor addition ratio.

The composite membrane is prepared by phase conversion method with in situ deposition method, and the BiOBr material has unique advantages for the degradation of organic dyes. The comprehensive experimental data can be known that the composite membrane prepared in this paper has high degradation efficiency and good durability for organic dyes.
