This chapter explores the multiplicity, formation, and porosity of organizational boundaries in new, fluid forms of production. Conceptualizing them as “partial organizations,” we argue that both the intentional design of organizational elements (such as membership, hierarchy, rules, monitoring, and sanctioning) as well as unintended adjustments of “unorganized” aspects drive boundary formation and impact boundary porosity. In addition, we contend that structuring dynamics will create specific trajectories for boundaries over time. Empirically, we further our theoretical framework on the basis of an in-depth case study of the Apache open-source software community during its formative years (1995–2002). We find that both the salience and formalization of boundaries increase over time. However, different conceptions of boundaries (such as efficiency, competence, power, and identity) become salient at different points in time. While design and adjustment drive boundary formation with regard to all boundary conceptions in our empirical case, porosity develops differently for each of them. We also demonstrate that the formalization of boundaries does not necessarily reduce boundary porosity, but actually may increase it.

Purpose – The research was carried out in order to study the composition of minerals, content of total-K, total-Ca, total-Mg, and exchangeable of K, Ca, Mg in volcanish ash from Sinabung volcano eruption.

Design/Methodology/Approach – The volcanic ash material in amount of 5 kg was collected from the depth of 0–20 cm and 21–41 cm. Mineral composition was determined by using line counting method; total contents of K, Ca, and Mg were measured by HCl 1N extraction, and exchangeable of K, Ca, and Mg was measured by NH₄OAc 1N pH 7.0 extraction.

Purpose – The results depicted in volcanic ash layer at the depth of 0–20 cm found some minerals such as plagioclase (34%), hypersthene (9%), augite (3%), hornblende/amphibole (5%), and volcanic glass (1%). These minerals were also found in different amounts at a depth of 21–41 cm. Hypersthene and amphibole were higher and augite was lower at a depth of 0–20 cm than 21–41 cm. The total content of K, Ca, and Mg was found to be 2.27%, 8.12%, and 2.28%, respectively, at a depth of 0–20 cm. The exchangeable of K, Ca, and Mg was found in an amount of 1.89 me/100 g, 20.71 me/100 g, and 1.62 me/100 g, respectively. The total content of K, Ca, and Mg was not available to plants but could potentially be as a source of plant nutrient after weathering while exchangeable form can be uptaken by plant directly.

Research Limitations/Implications – Based on the composition of the minerals, total, and exchangeable of K, Ca, and Mg that the material of volcanic ash, it could potentially be used as source of fertilizers.

Originality/Value – The composition of primary minerals contained in volcanic ash and to know the amount of elements K, Ca, and Mg-associated minerals either in total or exchange.

This chapter starts with two initial questions: Why, despite the fact that most large companies and organizations have protocols and instances for handling complaints to address gender violence, on many occasions, asymmetric relationships persist and no structural changes are observed in most of them? Can the culture of the environment determine resistance to change within organizations, or are the new processes part of an isomorphic organizational response to environmental pressures? To answer these questions, macroeconomic indicators of development and the gender gap are shown, to later explore the relationship between the construction of gender as a product where multiple variables converge and the gap that exists between women and men in organizations. Regardless of the economic wealth of a country, the incorporation of gender protocols does not always yield positive results. From a neo-institutional theoretical perspective and gender studies, the existence of a structural pressure to align subjects in dichotomous categories is proposed. Added to the visible asymmetries are the invisible costs for women and men: violence, invisibility, and underrepresentation. It is proposed to recognize the cultural conditions and the different degrees of organizational porosity to promote an intervention on three levels: from the subject in the organization; in the organizational field, structure, positions, processes, and products, and through a political praxis.

Composites based on fiber are commonly used in high-performance building materials. The composites mostly use petrochemically derived fibers like polyester and e-glass, due to their advantageous material features like high stiffness and strength. All the same, these fibers also have important shortcomings related to energy consumption, recyclability, initial processing expense, resulting health hazards, and sustainability. Increasing environmental awareness and new sustainable building technologies are driving the research, development, and usage of “green” building materials, especially the development of biomaterials.

In this chapter, the natural fiber evaluation approach is applied, which covers a diverse set of criteria. Consequently, the comparative assessment of diverse natural fiber types is applied through the use of an expert decision system approach. The best performing fiber choice is made by comparatively evaluating the materials related to green building. The proposed fiber can be used and applied by green building material manufacturing companies in various countries or locations as a reference when selecting the fiber with the best performance.

Stakeholders often engage in actions aimed at either benefitting or punishing firms for their behaviour. Such behaviours can have very serious implications for various types of firm performance, including financial performance. Though one might expect that the investigation of possible precursors of such “stakeholder action” would be a priority of researchers in stakeholder theory, to date research within the stakeholder literature directed towards understanding stakeholder behaviour has been somewhat scarce. In this chapter, I present common themes and assumptions that prevail in the existing research on stakeholder action, identify certain important questions concerning such assumptions and suggest avenues for future research on stakeholder behaviour.

This chapter aims to discuss the segmented city in the less developed world, focusing on its informal settlements. The main assumption is that the walls of informal settlements change from rigid to fuzzy ones, as they are analyzed using finer scales. In order to show this change, this chapter is divided into four sections. The first section analyzes the changes in two types of urban structure model: the segregated city model and the segmented city model. The second section describes the changes in governmental intervention models for informal settlements in Latin American cities, emphasizing what has been happening in the city of Recife, Brazil. The third section investigates the fact that, despite the changes in terms of governmental intervention models for informal settlements, there are still limits on the official city maps that effectively impede any appropriate representation of them. In order to show the gaps between the official cartographic representations and the reality of informal settlements, the last section of this chapter analyzes in more depth the walls of one specific informal settlement in Recife called Brasília Teimosa. This finer scale analysis allows us to see that its walls are even more fuzzy and permeable than the walls of the many formal settlements.

Adsorption parameters (e.g. Langmuir constant, mass transfer coefficient and Thomas rate constant) are involved in the design of aqueous-media adsorption treatment units. However, the classic approach to estimating such parameters is perceived to be imprecise. Herein, the essential features and performances of the ant colony, bee colony and elephant herd optimisation approaches are introduced to the experimental chemist and chemical engineer engaged in adsorption research for aqueous systems. Key research and development directions, believed to harness these algorithms for real-scale water treatment (which falls within the wide-ranging coverage of the Sustainable Development Goal 6 (SDG 6) ‘Clean Water and Sanitation for All’), are also proposed. The ant colony, bee colony and elephant herd optimisations have higher precision and accuracy, and are particularly efficient in finding the global optimum solution. It is hoped that the discussions can stimulate both the experimental chemist and chemical engineer to delineate the progress achieved so far and collaborate further to devise strategies for integrating these intelligent optimisations in the design and operation of real multicomponent multi-complexity adsorption systems for water purification.
