On Case Study Methodology
Authors: Johansson Rolf 
Published: January 2021

A case study is expected to capture the complexity of a single case, which should be a functioning unit, be investigated in its natural context with a multitude of methods, and be contemporary. A case study and, normally, history focus on one case, but simultaneously take account of the context, and so encompass many variables and qualities. When a physical artefact is the case the gap between case study and history tends to diminish and case studies often become more or less historical case studies. Case study methodology also bridges the gap between quantitative and qualitative methods in the social sciences. Still the different concepts of validation in quantitative and qualitative research sometimes create confusion when they are combined, as they often are in case studies.
The case might be studied with an intrinsic interest in the case as such, or with an interest in generalising. When a generalisation is based on the deductive principle, the procedure of testing hypothesis is used. A second mode of generalisation is inductive theory-generation, or conceptualisation. The third mode depends on the principle of abduction. Abduction is the process of facing an unexpected fact, applying some rule and, as a result, positing a case that may be. But there are two kinds of abduction: One is when a case is created from a few facts; for instance, historical data or clues. The other is operative when generalisations are made from known cases and applied to an actual problem situation by making appropriate comparisons. This is also called naturalistic generalisation. In a case study, the different modes of generalisation are often combined.
The conclusion is that case studies has the potential for further development through the mastery of the combination on different levels of techniques, methodologies, strategies, or theories, like; the combination of case study and history, which is important when the case is an artefact; the combination of differing quality standards in qualitative and quantitative research, which are difficult to codify; and the combination of different modes of generalisation.
Contribution of Balcony on Thermal Comfort : Rusunawa Surabaya

Published: January 2021

Dwelling, which is a basic human need (Maslow, 1970) should act as an object of technology that serves as a place for individuals or families to conduct all their daily activities in order to meet their needs in life. In case of sustainability, thermal comfort is one of the most important comfort conditions that must be achieved (Szokolay SV, 1980). Proper air movement control may lessen the demand for energy, thus reducing the expense of providing a comfortable home (Boutet, 1987). However, to ensure the acceleration of air movement, the availability of both inlet and outlet openings in the building or space become an absolute requirement (Olgyay Victor, 1973).
Rusunawa is a typical rental-apartment in Indonesia that served for low income families. The types of existing space generally include: a multi-functional space, a kitchen, and a bathroom/WC, and sometimes is furnished by a balcony. There is only one living space in rusunawa that is the multi-functional space which is often used for: living, sleeping, studying, watching TV, eating, storing, child-caring, and probably more other functions. Not to mention if the family has a home-based business. Among rusunawa unit types that existed in all fourteen locations in Surabaya, some of them were built without a really outdoor balcony, meaning that the balconies were provided indoor, instead of in the cantilever system. These indoor balconies accommodate the same household activities as those of outdoor balconies. However, the contribution to the internal thermal comfort may not be the same.
By using Ecotect analysis 2011 program, This research intends to investigate the comparison of thermal conditions of the inner space between rusunawa unit having a balcony (outdoor), and rusunawa unit without a balcony (indoor). The result of this comparison is meant to convince the contribution of unit having a balcony to the thermal comfort of inner space, to ensure whether the design of the future rusunawa units should be equipped with a balcony or not. To further reassure its contribution, this experiment is continued by comparing between unit having just a balcony and unit having a balcony that equipped with sun-devices.
Summertime Impact of Climate Change on Multi-Occupancy British Dwellings
Authors: Shikder Shariful , Mourshed Monjur , Price Andrew 
Published: January 2021

Recent climate change projections estimate that the average summertime temperature in the southern part of Great Britain may increase by up to 5.4°C by the end of the century. The general consensus is that projected increases in temperature will render British dwellings vulnerable to summer overheating and by the middle of this century it may become difficult to maintain a comfortable indoor environment, if adaptation measures are not well integrated in the design and operation of new dwellings, which are likely to remain in use beyond the 2050s. The challenge is to reduce overheating risks by integrating building and user adaptation measures, to avoid energy intensive mechanical cooling. Developing guidelines and updating building regulations for adaptation, therefore, requires an understanding of the baseline scenario; i.e. the performance of existing buildings in future climates.
This paper aims to investigate the performance of new-build multi-occupancy British dwellings for human thermal comfort in the present-day and projected future climates in four regional cities: Birmingham, Edinburgh, London and Manchester. Evaluations are carried out by a series of dynamic thermal simulations using widely adopted threshold temperature for overheating, as well as adaptive thermal comfort standards. This study thus offers a unique perspective on regional variations of performance and provides a clearer snapshot because of the use of more appropriate adaptive comfort standards in the evaluations. Finally, the paper sheds light on possible personal and building adaptation measures to alleviate overheating risks.
Post-Occupancy Investigation of two Open Building Projects
Authors: Shanshan LI 
Published: January 2021

Under the concept that housing was an act instead of a product, John Habraken launched a campaign against mass housing in the 1960s. His counterattack was architecturally and institutionally developed afterwards, and fully expressed by the so-called Open Building, in which users could make decision regarding their dwellings and easily re-arrange them. A number of experimental projects were subsequently constructed worldwide.
After years, the actual situation of use of these projects is, to a certain extent, unknown. Their facades may have faded, their pipelines may be ageing, and the design may be out of fashion. Correspondingly, various changes are expected. Could these changes be controlled in the original design? Were these projects enhanced after the changes? Did the users have a positive response? These questions are far from being answered.
This article is based on the post-occupancy investigation of two Open Building projects, the “Molenvliet Project” in the Netherlands and the “Wuxi Experimental Project” in China, which played an exemplary role, especially in the early years. In this study, the users’ assessment of their living environment was highly emphasised, and the changes to the both exterior and interior were specifically recorded. The purpose of the investigation is to determine how the architects’ intention was practised, and to learn from them.
Hard/heart worker: work intensification in purpose-driven organizations
Authors: Dupret Katia , Pultz Sabina 
Published: January 2021

PurposeThe paper seeks to illuminate the intersection between doing greater good in the world and the self-disciplining that comes along with it. The paper raises a discussion on how purpose-driven organizations with a sustainability focus should be concerned about internal social sustainability in order to maintain consistency between external purpose and internal well-being of employees.Design/methodology/approachThis article investigates the interrelations between purpose-driven organizations' quest for social sustainability and internal work conditions exemplified through experiences with work intensification. A governmentality studies approach is applied to investigate how employees' perceptions of doing greater good in the world also become a productive self-disciplining strategy that potentially increases work intensification and simultaneously result in an instrumentalization of working for greater sustainability.FindingsWorking with an organizational sustainability purpose can, in some situations, create dilemmas that may decrease employee well-being as it demands continuous negotiation of boundaries between paid work and free time, meaningfulness and work devotion, self-management and work intensification.Originality/valueThe paper raises a discussion on how purpose-driven organizations with a sustainability focus should be concerned about internal (social) sustainability in order to maintain consistency between external purpose and internal well-being of employees.
Challenging absolute executive powers in times of corona: re-examining constitutional courts and the collective right to public contestation as instruments of institutional control
Authors: Eichler Jessika , Sonkar Sumit 
Published: January 2021

Purpose
The CoViD-19 pandemic has brought about a panoply of institutional challenges both domestically and in the international arena. Classical constitutional theory thereby underwent a reinvention by the executive for the sake of speedy policy action and to the detriment of institutional control while favouring authoritarian forms of governance. This paper concerns itself with institutional responses to such developments, placing emphasis on the role of the judiciary and people*s in contesting emergency decrees and other executive orders, especially where fundamental rights are infringed upon. The paper aims to explore the difficulties arising with exerting absolute executive powers during the health crisis, the respective role assumed by constitutional courts and the impact of the new governance paradigm on forms of public contestation, also as a means of quasi institutional control.

Design/methodology/approach
Indeed, the right to health may be translated into political discourse and become foundational to security and public interest paradigms. This may result in a shrinking public space given the constraints to the freedom of movement. In the name of public safety, the (collective) right to assembly, expression and protest have been submitted to major limitations in that regard.

Findings
Ultimately, this re-opens debates on the meaning of absolute rights and contextualities of derogations, as well as the reconcilability of civil and political rights and economic, social and cultural rights. It also exposes social inequalities, social justice dimensions and vulnerabilities, often exacerbated by the health crisis; migrant rights demonstrably face particularly severe and intersectional forms of violations.

Originality/value
Particular values lie with the interdisciplinary approach embraced in this paper; the authors draw on a variety of social sciences disciplines to shed light on this very current issue. Both theoretical and empirical methods are used and combined here, making sense of the underlying logic of virus governance and its impacts on fundamental rights.
Mapping the path to certification of metal laser powder bed fusion for aerospace applications
Authors: Gibbons Duncan William , Serfontein Jean-Pierre Louis , van der Merwe André Francois 
Published: January 2021

Purpose
The purpose of this paper is to identify and define the certification lifecycle of laser powder bed fusion for aerospace applications from equipment acquisition and installation to production, part acceptance and continuous improvement activities.

Design/methodology/approach
A top–down systems engineering approach is performed consisting of concept development, requirements engineering and systems architecting. This approach is taken from the perspective of a production organization.

Findings
A certification roadmap is proposed that references industry requirements at the relevant phases of the roadmap. Each phase of the roadmap acts as a decision gate for progression to the next.

Originality/value
Qualification and certification of metal laser powder bed fusion is currently a challenge within the aerospace industry. From an aerospace point of view, the qualification and certification of this relatively new manufacturing process should not have to be any different from traditional manufacturing processes, although with extensive quality control and regulatory oversight. This paper proposes a means for fulfilling these requirements chronologically and provides guidance on ensuring such quality control throughout the manufacturing system lifecycle. This roadmap provides insight into the qualification and certification of laser powder bed fusion for aerospace applications and provides value for future industrial feasibility studies.
Multi-scale damage analysis and fatigue behavior of PLA manufactured by fused deposition modeling (FDM)
Authors: Vanaei Hamid Reza , Shirinbayan Mohammadali , Vanaei Saeedeh , Fitoussi Joseph , Khelladi Sofiane , Tcharkhtchi Abbas 
Published: January 2021

Purpose
Fused deposition modeling (FDM) draws particular attention due to its ability to fabricate components directly from a CAD data; however, the mechanical properties of the produced pieces are limited. This paper aims to present the experimental aspect of multi-scale damage analysis and fatigue behavior of polylactic acid (PLA) manufactured by FDM. The main purpose of this paper is to analyze the effect of extruder temperature during the process, loading amplitude, and frequency on fatigue behavior.

Design/methodology/approach
Three specific case studies were analyzed and compared with spool material for understanding the effect of bonding formation: single printed filament, two printed filaments and three printed filaments. Specific experiments of quasi-static tensile tests coupled with microstructure observations are performed to multi-scale damage analysis. A strong variation of fatigue strength as a function of the loading amplitude, frequency and extruder temperature is also presented.

Findings
The obtained experimental results show the first observed damage phenomenon corresponds to the inter-layer bonding of the filament interface at the stress value of 40 MPa. For instance, fatigue lifetime clearly depends on the extruder temperature and the loading frequency. Moreover, when the frequency is 80 Hz, the coupling effect of thermal and mechanical fatigue causes self-heating which decreases the fatigue lifetime.

Originality/value
This paper comprises useful data regarding the mechanical behavior and fatigue lifetime of FDM made PLA specimens. In fact, it evaluates the effect of process parameters (extruder temperature) based on the nature of FDM that is classified as a thermally-driven process.
How multinational corporations and nonprofits collaborate for sustainability: assessing social partnerships from China
Authors: Yin Juelin 
Published: January 2021

PurposeThis paper aims to understand the characteristics, factors and contingencies of social partnerships between multinational corporations (MNCs) and nonprofits in the context of sustainability that enable or impede the value creation outcome of the collaboration.Design/methodology/approachA multi-case study with 12 social partnerships operating in China was investigated considering their relative representativeness and different value creation outcomes.FindingsThe author presents a snapshot of the current state and unique differences of social partnerships in China, whereas the existing literature has mostly addressed the topic from a Western context. Moreover, the author highlights the key determinants and contextual features that influence the value creation outcome of social partnerships in China.Research limitations/implicationsThis study concentrates on the social partnerships in the largest emerging country context of China, and the representativeness of data collected from a small sample may be challenged. Likewise, the 12 social partnerships studied are similar in design but vary in sustainability focus. To test the validity of the theorizing, the study calls for future research to apply the proposed theoretical framework across various contexts across both developing and developed world.Practical implicationsThe paper provides guidance to corporate managers and nonprofit decision-makers on how to improve their social partner initiation, operations and governance so as to generate greater collaborative value out of social partnerships in the Chinese market.Social implicationsThis study contributes to the social partnership literature, which has been dominant in the Western context, by offering case evidences from China.Originality/valueThe study shows that social partnerships are increasingly initiated and sustained in the context of sustainability and corporate social responsibility, with the majority oriented toward “satisficing” instead of “optimizing” and represented mostly with a “philanthropic” and “transactional” approach. The author particularly notes the salience of social exchange, with social partnerships serving as an indirect relational instrument for MNCs to navigate stakeholder relationships in the Chinese market, especially with the dominant resource holder such as the government.

Published: January 2021

Purpose
Low-Ag SAC solder will lead to a series of problems, such as increased the melting range and declined the solderability and so on. These research studies do not have too much impact on the improvement of solders’ performance but were difficult to achieve satisfactory results. It is urgent to develop new soldering technology to avoid the bottleneck of lead-free solder. low-temperature-stirring soldering and ultrasonic-assisted soldering was developed in the authors’ early work, but slag inclusion and pore would gather and grow up to lead decreasing of the shear strength. In this paper, Cu/SAC0307 +Zn power/Cu joints with ultrasonic-assisted at low-temperature was successfully achieved.

Design/methodology/approach
45um Zn-powder and SAC0307 No.4 solder powder were mixed to fill the Cu-Cu joint, and the content of Zn-powder were 0 and 5%, 7.5% and 10%, 12.5% and 15% respectively. During the soldering process under ambient atmosphere %252C the heating platform provided a constant 220%253 F and the ultrasonic vibrator applied a constant pressure of 4 MPa to the copper substrate. The soldering process was completed after holding 70 s at 300 W.

Findings
The Zn particles made the IMC at the joint interface and in the soldering seam from scallop-type Cu6Sn5 to flat-type Cu5Zn8. The shear strength of joints without Zn was only 12.43 MPa, the shear strength of joints with 10% Zn reached a peak of 34.25 MPa, and the shear strength of joints containing 10% Zn was 63.71% higher than that of joints without zinc particles, and then the shear strength decreased. In addition, with the increase of zinc content, the fracture mode of the joint changed from the brittle fracture of the original layered tears to the mixed tough and brittle fracture.

Originality/value
A new method that Zn micron-size powders and SAC0307 micron-size powders was mixed to fill the joint, and successfully achieved micro-joining of Cu/Cu under ultrasonic-assisted without flux at low-temperature.
DMSP synthesis genes distinguish two types of DMSP producer phenotypes
Authors: McParland Erin L. , Lee Michael D. , Webb Eric A. , Alexander Harriet , Levine Naomi M. 
Published: January 2021

SummaryDimethylsulfoniopropionate (DMSP) is an important organic carbon and sulfur source in the surface ocean that fuels microbial activity and significantly impacts Earth's climate. After three decades of research, the cellular role(s) of DMSP and environmental drivers of production remain enigmatic. Recent work suggests that cellular DMSP concentrations, and changes in these concentrations in response to environmental stressors, define two major groups of DMSP producers: high DMSP producers that contain ≥ 50 mM intracellular DMSP and low DMSP producers that contain < 50 mM. Here we show that two recently described DMSP synthesis genes (DSYB and TpMT2) may differentiate these two DMSP phenotypes. A survey of prokaryotic and eukaryotic isolates found a significant correlation between the presence of DSYB and TpMT2 genes and previous measurements of high and low DMSP concentrations, respectively. Phylogenetic analysis demonstrated that DSYB and TpMT2 form two distinct clades. DSYB and TpMT2 were also found to be globally abundant in in situ surface communities, and their taxonomic annotations were similar to those observed for isolates. The strong correlation of the DSYB and TpMT2 synthesis genes with high and low producer phenotypes establishes a foundation for direct quantification of DMSP producers, enabling significantly improved predictions of DMSP in situ.
Strengthening women's participation in the traditional enterprises of sub‐saharan Africa: The role of corporate social responsibility initiatives in Niger delta, Nigeria
Authors: Okolo‐Obasi Elda N. , Uduji Joseph I. , Asongu Simplice A. 
Published: January 2021

AbstractThe purpose of this paper is to critically examine the multinational oil companies (MOCs) corporate social responsibility (CSR) initiatives in Nigeria. Its special focus is to investigate the impact of the global memorandum of understanding (GMoU) on development of rural women's traditional enterprises in the Niger Delta region. A total of 2,400 women were sampled across the region. Results from the use of a combined propensity score matching and logit model indicate that the GMoU model of the CSR has recorded significant success in supporting farming and fishing transformation generally, but has also undermined those initiatives that focused on empowering rural women in traditional enterprises, due to the cultural and traditional context in the region. This causes both direct harm to women and their children, and wider costs to African economies. It implies that if the GMoU interventions are not targeted to raise women's economic status and to deter aggression, invariably they may contribute towards reducing the participation of women in economic, political and social development and, by extension, dampen efforts in deterring poverty and achieving the sustainable development goals in sub‐Saharan Africa.
