Abstract
Purpose
This purpose of this paper is to address the problem of reducing energy consumption in existing buildings using advanced noninvasive interventions (NVIs).
Design/methodology/approach
The study methodology involves systematically developing and testing 18 different NVIs in six categories (glazing types, window films, external shading devices, automated internal shades, lighting systems and nanopainting) to identify the most effective individual NVIs. The impact of each individual NVI was examined on an exemplary university educational building in a hot climate zone in Egypt using a computational energy simulation tool, and the results were used to develop 39 combination scenarios of dual, triple and quadruple combinations of NVIs.
Findings
The optimal 10 combination scenarios of NVIs were determined based on achieving the highest percentages of energy reduction. The optimal percentage of energy reduction is 47.1%, and it was obtained from a combination of nanowindow film, nanopainting, LED lighting and horizontal louver external. The study found that appropriate mixture of NVIs is the most key factor in achieving the highest percentages of energy reduction.
Practical implications
These results have important implications for optimizing energy savings in existing buildings. The results can guide architects, owners and policymakers in selecting the most appropriate interventions in existing buildings to achieve the optimal reduction in energy consumption.
Originality/value
The novelty of this research unfolds in two significant ways: first, through the exploration of the potential effects arising from the integration of advanced NVIs into existing building facades. Second, it lies in the systematic development of a series of scenarios that amalgamate these NVIs, thereby pinpointing the most efficient strategies to optimize energy savings, all without necessitating any disruptive alterations to the existing building structure. These combination scenarios encompass the incorporation of both passive and active NVIs. The potential application of these diverse scenarios to a real-life case study is presented to underscore the substantial impact that these advanced NVIs can have on the energy performance of the building.

Abstract
Social movement scholarship convincingly highlights the importance of threats, political opportunities, prior social ties, ideological compatibility, and resources for coalition formation. Based on interviews with Palestinian, Israeli, and international activists involved in two transnational coalitions in Israel/Palestine, this chapter illustrates the emergence of transnational coalitions, particularly those that cross polarized ethno-national divides, depends not only on such facilitators, but also, and critically, on the belief that such diverse cooperation is strategic. I argue these unique coalitions intentionally formed with individuals and organizations situated in different national communities out of a strategic decision by the Palestinian initiators, given the closed political opportunity structure they faced domestically, to enlarge the scope of conflict by drawing in new people and communities who may have some leverage on the Israeli government. Consequently, this chapter also makes clear that partners in the Global South make intentional choices about who to partner with, and that the agency is not solely linked with their more privileged partners in the Global North (cf., Bob, 2001; Widener, 2007). Finally, it illustrates that coalition partners are recruited not only because of social ties, prior histories of interaction, ideological similarity, and shared organizational framing, but also due to key considerations including perceptions of what the ethno-national diversity, varying networks, and differing privileges make available.

Abstract
Synopsis
The traditional and still dominant logic among nearly all empirical positivist researchers in schools of management is to write symmetric (two-directional) variable hypotheses (SVH) even though the same researchers formulate their behavioral theories at the case (typology) identification level.

Meyer, collaborator; H. J. Coleman Jr., contributor]. New York, NY: McGraw Hill) typologies of organizations’ strategy configurations (e.g., “Prospectors, Analyzers, and Defenders”) are iconic examples of formulating theory at the case identification level. When testing such theories, most researchers automatically, nonconsciously, switch from building theory of beliefs, attitudes, and behavior at the case identification level to empirically testing of two-directional relationships and additive net-effect influences of variables. Formulating theory focusing on creating case identification hypotheses (CIH) to describe, explain, and predict behavior and then empirically testing at SVH is a mismatch and results in shallow data analysis and frequently inaccurate contributions to theory. This chapter describes the mismatch and resulting unattractive outcomes as well as the pervasive practice of examining only fit validity in empirical studies using symmetric tests. The chapter reviews studies in the literature showing how matching both case-based theory and empirical positivist research of CIH is possible and produces findings that advance useful theory and critical thinking by executives and researchers.

Abstract
Purpose
This chapter examines the existing work on tangible user interfaces (TUIs) and focuses on tangible programming with the scope to enlighten the opportunities for innovation and entrepreneurship in this particular domain.
Methodology/approach
In the first section, we start by presenting in short the history of TUIs and then focus on tangible programming presenting the different design approaches. Then we present the opportunities for innovation and guidelines for future products.
In the second section, we review the entrepreneurial activities that combine educational toys and TUIs.
Findings
The main finding of this chapter is that although TUI design and research are still in its infancy and more design guidelines and research are required to further bridge the digital and the physical world, the first signs of entrepreneurship promise a bright future.
Research limitations
Limitations arise from the fact that many companies keep many of their financial data confidential. Thus, it was impossible to include and validate all the information that we intended to present.
Practical implications
Initially, this chapter motivates and challenges scientist to find novel innovative solutions in the field. Then, reveals the entrepreneurial opportunities and potential customers. Finally, shows the funding sources and how tangible products are offered in the market.
Social implications
We propose a new kind of toys that might alter and expand science, technology, engineering, and mathematics (STEM) in education.
Originality/value
This chapter appears to be unique in the sense that is the first that reports simultaneously on TUIs, entrepreneurship, and innovation.
