Though production rates for construction materials are generally available, potential capacity on a global scale is poorly understood. Commencement of infrastructure projects to address climate change, such as dikes and levees, could increase demand making critical resources scarce. Since increasing production capacity of scarce products can be a challenge, understanding current potential capacity is an imperative. The purpose of this paper is to develop a new method to assess capacity and to create one such global estimate for cement.

The proposed global hybrid method creates a global estimate of cement production capacity in four steps: collect capacity and production data from existing reports; select top regional capacity holders; compute regional utilisation; back‐calculate capacity from production.

The method overcomes shortfalls of other methods, but – like all estimating methods – is inherently limited by the amount of data available. It nonetheless provides economists, climate change scientists, government officials, investors, and other researchers a better understanding of current maximum global cement capacity.

Most studies only focus on industry demand and actual production, because these forces drive commodity pricing. Capacity is generally estimated either through surveying goods‐producing industries at the plant level or examining economic data. Methods that employ these types of analysis are useful for regional estimates of production, but are ineffective at the global scale.

To implement and assess an intervention designed to promote gender equity and organizational change within STEM departments in two Colleges at a single Research High university. Department climate impacts the retention and success of women faculty.

A survey was administered both before and after the department intervention in order to capture departmental change on variables that measure a positive climate for female faculty.

Across all of the science and engineering departments, levels of Collective Efficacy toward Gender Equity significantly increased while levels of Conflict significantly decreased after the department facilitation. In the science departments, the level of Vicarious Experience of Gender Equity among faculty significantly increased while in the engineering departments levels of faculty Dependence significantly decreased. There was a statistically significant decrease in Optimism about Gender Equity among the science faculty.

Organizational change within universities has been documented as slow and labor intensive. Departmental climate, particularly interactions with colleagues, remains an area wherein women continue to feel excluded. The departmental intervention resulted in measurable improvements in key aspects of climate critical to women’s success (e.g., reductions in conflict and dependence; increases in collective efficacy) as well as more realistic view of the effort needed to attain gender equity (decrease in Optimism).

Hot and humid climates (HHCs) are potential environmental hazards that directly affect construction workers' health and safety (HS) and negatively impact workers' productivity. Extensive research efforts have addressed the effects of HHCs. However, these efforts have been inconsistent in their approach for selecting factors influencing workers in such conditions. There are also increasing concerns about the drop-off in research interest to follow through intrusive and non-real-time measurements. This review aims to identify the major research gaps in measurements applied in previous research with careful attention paid to the factors that influence the intrusiveness and selection of the applied data collection methods.

This research integrates a manual subjective discussion with a thematic analysis of Leximancer software and an elaborating chronological, geographical and methodological review that yielded 701 articles and 76 peer-reviewed most related articles.

The literature included the physiological parameters as influencing factors and useful indicators for HHC effects and identified site activity intensity as the most influencing work-related factor. In total, three main gaps were identified: (1) the role of substantial individual and work-related factors; (2) managerial interventions and the application of the right time against the right symptoms, sample size and measurement intervals and (3) applied methods of data collection; particularly, the intrusiveness of the utilised sensors.

The focus of researchers and practitioners should be in applying nonintrusive, innovative and real-time methods that can provide crew-level measurements. In particular, methods that can represent the actual effects of allocated tasks are aligned with real-time weather measurements, so proactive HHC-related preventions can be enforced on time.

This review contributes to the field of construction workers' safety in HHCs and enables researchers and practitioners to identify the most influential individual and work-related factors in HHCs. This review also proposes a framework for future research with suggestions to cover the highlighted research gaps and contributes to a critical research area in the construction industry.

The literature on women of color (WOC) faculty is replete with accounts of marginalization (Balderrama, Texeira, & Valdez, 2006; Benjamin, 1997; Garcia, 2005; John, 1997; Li & Beckett, 2006; McKay, 1997; Reyes, 2005). For instance, Balderrama et al. (2006) explains, “I come from a family of survivors, but I never realized it would come to that in academia …Little did I know I was entering one of the bastions of conservative ideology and practices – a far cry from a meritocracy working for the public good” (Balderrama et al., 2006, p. 224). Concomitantly, the higher education literature extols the presence of race and gender diversity because they are associated with elevated learning outcomes and intercultural engagement (Chang, 2002; Gurin, 1999; Milem & Hakuta, 2002). Therein lies the quandary. Given the importance of illuminating the challenges that WOC face within the academy, how then can that discourse be broadened to include empirical and theoretical claims about the relationship between WOC agency and structural transformation? In other words, how can WOC move beyond or within structural constraints to contribute to the teaching and learning environment? Equally important, how does the presence of WOC encourage a diversity conversation beyond student learning outcomes to one that emphasizes social equity? This chapter intends to participate in these emergent conversations in two ways. First, drawing from an empirical study of Black female faculty, I discuss how the participants contributed to their institutions and how those contributions embody and expand on the following diversity narratives: structural access and climate, learning outcomes, intercultural competencies, and meritocracy. Second, I theoretically expound upon the Black female faculty findings to discuss implications for similarly situated WOC. In all, this chapter demonstrates that difference – a woman of color difference – dislodges reactionary strongholds within the academic enterprise.

The purpose of this paper is to review many of the diverse metaphors and labels that are used to highlight insights into glass ceilings – the obstacles hindering women reaching the top levels of organizations.

The development of metaphors and labels related to theories about the causes and consequences of glass ceilings are discussed. They are classified according to whether or not they infer women play a role in creating glass ceilings.

It is concluded that most metaphor‐linked explanations focus on discrimination and prejudice towards women seeking leadership positions. A small number of metaphors target characteristics of women as causes for the gender inequality in leadership and upper management.

Even though there is a plethora of metaphors highlighting obstacles and prejudice against women leaders and several metaphors have been part of the popular lexicon for at least three decades, metaphors do not appear to have greatly helped to quicken the dismantling of glass ceilings.

This is a unique approach to reviewing literature in this area.

This introduction sets forth the main themes of the volume, reviews the methods employed by the contributors, and demonstrates the relationships among the chapters.

Each of the chapters demonstrates the gendered nature of the academy and some of the ways in which women, especially women in science, technology, engineering, and mathematics (STEM) disciplines, are disadvantaged. None of them provides complete catalogues of the issues confronting women and none reach definitive conclusions regarding the ways and means of transforming the academy. Additional research and experimentation will be required.

The gender transformation of the academy holds the promise of more opportunities for women, especially but not only in STEM disciplines and higher administration, and greater probability of balance between work and personal life for all.

The chapter serves as an overall introduction to the volume and the subject matter more generally.

This paper aims to review the history of black and minority ethnic housing associations in England since the arrival of Commonwealth migrants.

Drawing on the theoretical framework of Lawrence and Buchanan (2017), the authors examine the interplay of institutional control, agency and resistance, in a highly racialized context.

The authors identify five phases in the development of grassroots organizers into housing associations, describing the different types of “institutional work” involved in challenging racialized institutions and establishing new institutions. The exercise of episodic power to achieve institutional agency created resistance from powerful actors seeking to maintain systemic power. The growing movement for black and minority ethnic housing fought to establish organizational legitimacy. Achieving this not only enabled them to serve and represent their communities but also entailed compromising more radical political agendas.

Racialized aspects are largely lacking from institutional theory, as are the actions of racialized individuals and organizations. In looking at a highly racialized context, the authors hope to contribute to understanding the institutional work done by such groups and the challenges they face as their efforts develop and become legitimated.

Robotics and automation are successful in construction, health and safety, but costs and expertise hinder their use in developing nations. This study examined mobile apps as a more accessible and affordable alternative.

This descriptive study explored the use of mobile apps in construction, health and safety management. It used a literature review to identify their availability, accessibility, and capabilities. The study consisted of four five stages: searching for relevant apps, selecting them based on versatility, examining their specific functions, removing untested apps and discussing their functions based on empirical studies.

A comprehensive literature review identified 35 mobile apps that are relevant to health and safety management during construction. After rigorous analysis, eight apps were selected for further study based on their relevance, user friendliness and compliance with safety standards. These apps collectively serve 28 distinct functions, including first-aid training and administration, safety compliance and danger awareness, safety education and training, hazard detection and warnings.

This study suggests that mobile apps can provide a cost-effective and readily accessible alternative to robotics and automation in health and safety management in construction. Further research is needed to accurately assess the efficacy of these apps in real-world conditions.

This study explored the use of apps in health and safety management, highlighting their diverse capabilities and providing a framework for project managers, contractors and safety officers to select suitable apps.

A physician–nurse relationship is a complex, professional and shared-decision-making process, which is an important predictor of high-quality patient care. The purpose of this paper is to explore the attitude of the physician–nurse relationship in Southern Lebanon hospitals.

A descriptive institutional cross-sectional study was conducted among different departments of three hospitals in Southern Lebanon using a validated Jefferson Scale of Attitude.

In sum, 89 physicians and 245 nurses accepted to participate. The nurses’ mean age was 32 and the physicians’ was 44. The mean score was found to be 46 for all participants, with significantly higher scores noted among nurses compared to physicians (48 vs 43, respectively) and higher scores among females compared to males (48 vs 46, respectively). However, the study scored no significant difference in relation to the degrees attained by nurses and the participants’ years of experience. The majority had agreed that the shortage in the nurses’ staff affects proper patient care delivery. One fourth of the physicians disagreed that nurses should be considered as a collaborator and colleague. Therefore, more work is required to improve this collaboration.

There is a complex relationship normally displayed by physicians and nurses, which cannot be easily interpreted and analyzed. Physicians and nurses may have given socially desirable responses while filling the questionnaire. Even more, this study was conducted in Hospitals in Southern Lebanon, and it would be nice to extend this study to include further hospitals in other regions in Lebanon as well.

Nurses had higher scores toward collaboration, with females scoring higher than males. However, overall scores are considered to be lower compared to other countries. Thus, more efforts should be done on improving this communication among nurses and physicians, through promoting inter-professional undergraduate and postgraduate education training toward more effective communication.

Quality of patient care would be improved if more work is done on improving the collaboration between physicians and nurses, and this was shown to be required as per study results.

There is a gap in literature assessing this important topic which is the collaboration and attitude of nurses and physicians toward their relationship in Lebanon. It is extremely important that efforts should be taken in order to determine the type of nurse–physician relationship in every local context as this relationship affects quality of patients’ care.
