Abstract

This chapter examines common managerial practices inspired by local values and ethics within Algerian companies, with a focus on managerial discretion surrounding corporate social responsibility (CSR) initiatives. The complexity of human, economic and institutional development realities within the Algerian context makes it a uniquely intriguing subject, yet little attention has been attributed to studying the manifestation of local values through CSR practices in this environment. The chapter presents a qualitative case study of six companies operating in Algeria, and coins CSR discretion as a local concept that reflects undertaking CSR actions while purposely not communicating over it. The influence of local values and ethics are most visible through (a) CSR initiatives powered by personal responsibility, (b) CSR discretion to preserve the value of one’s actions, referred to as the ‘neya’, and (c) the common forces that shape individual values which then manifest through management practices.

Abstract

Purpose

The stabilization of earthen blocks improves their mechanical strength and avoids adobe construction erosion due to rainwater. However, the stabilization affects the thermal properties of the earthen blocks, and thus their capacity to provide adequate thermal comfort to occupants. This article examines the influence of cement and geopolymer binders on thermal comfort in compressed earthen buildings in hot and arid climates.

Design/methodology/approach

The test cell is on the building platform in Burkina Faso. The building is made of compressed earth blocks (CEB) consisting of laterite, water and binder. The thermal models of the building were implemented in EnergyPlus v9.0.1 software. Empirical validation is used to check whether the model used for the thermal dynamic simulation can reproduce with accuracy the thermal behavior in a real situation. The adaptive thermal comfort model of ASHRAE 55–2010 was used to assess thermal comfort in long-term hot and dry tropical conditions.

Findings

The results show that the CEB buildings remain hot despite the use of cement or geopolymer binder. Indeed, with both cement and geopolymer binders, on a daily basis, 19 h and 15 h are uncomfortable during, respectively, the hot and cold seasons. An increase of 1% in cement content raises the comfort hours by 9.2 h during the hot season and 11.7 h during the cold season. Hence, the comfort time varies linearly with the cement content in the building material. Moreover, there is no linear relationship between comfort time and geopolymer rate.

Research limitations/implications

Complementary work should also assess the influence of stabilization on building humidity levels. In fact, earthen materials are very sensitive to outdoor humidity and indoor humidity affects thermal comfort even if it is not taken into account in the ASHRAE adaptive thermal comfort model.

Practical implications

The present study will certainly contribute to a better valorization of clay potential in countries with similar climatic conditions.

Social implications

The use of geopolymer binder is a suitable ecological option to replace the cement binder. It is important to mention that nighttime comfort can be increased through passive strategies such as natural ventilation.

Originality/value

Most CEB material stabilization analyses including cement and geopolymer ones were mostly investigated at the laboratory scale and less at the building scale. Also, the influence of the binder rate on the thermal performance of buildings made of cement and geopolymer has not yet been assessed. This paper fills this gap of knowledge by assessing the impact of cement and geopolymer binder rates on the thermal comfort of CEB dwellings.

Abstract

Ecology is a word commonly used in many circles with a focus on the environment and human interactions with it. Human ecology as a concept studies human interaction with the environment in different cultures. Human cultural backgrounds differ and the way the traditional beliefs influence human activities varies from place to place. In entrepreneurship, traditional values can play a role as they often shape the character of practitioners. In the quest for sustainable development, one cannot underestimate the influence of these cultural tenets in shaping the dynamics of the practitioners’ activities. This chapter explores the role of African cultural beliefs, philosophies in cultivating principled entrepreneurship. It presents some traditional values that influenced the mindset of entrepreneurs in the past towards ethical work. These tenets guided the dynamics of trade and responsible management of resources for the benefit of one’s community and of oneself.

Abstract

Wisdom from Africa comes in different forms: proverbs, adages, folktales with moral lessons, the use of figurative speech which transmit deep messages, a variety of wise sayings, songs, etc. Such wisdom guided many interactions including those relating to trade, entrepreneurship and other activities that drive the dynamics of economies. African communities are well known for a sense of communal living and a concern for others often manifested as solidarity. Aggregating the combined data from the preceding chapters, this final chapter in Volume 2 of Responsible Management in Africa explores the role of these two realities that are part of the African cultural heritage in promoting solidarity and inclusion. Four themes emerge: values-based education, mutual trust, personal social responsibility and sustainability factors. Beyond these four, since responsible businesses ought to have inclusive growth among their goal, they can also apply the knowledge of traditional values such as Ubuntu and Omoluabi for tackling challenges to sustainable development and contributing to attaining an ethical economy.

Abstract

Purpose

A major challenge faced by West Africa is to find comfortable housing as a result of climate change and population growth. The climatic adaptation of buildings and their indoor environment become an essential condition for maintaining the health and productivity of the occupants. This paper proposes a model to assess the thermal comfort of naturally ventilated buildings in hot and dry climates in Burkina Faso.

Design/methodology/approach

The proposed method is an adaptive model which relies on a combination of parameters such as the operative temperature, the new effective temperature and the basic parameters of thermal comfort. It consists in proposing the zones of thermal comfort on the diagram of the humid air for each climatic region.

Findings

A decision-making tool is set up for evaluating the comfort of buildings to better consider the bio-climatic concept through a long-term comfort index. This comfort index is defined and is used to assess the degree of thermal discomfort for various types of housing. Two natural ventilation pilot buildings located in Ouagadougou were considered. The results show that the pilot building whose wall are is made of Earth blocks achieves 26.4% of thermal comfort while the building made of hollow cement block achieves 25.8% of thermal comfort.

Originality/value

The decision-making tool proposed in the present study allow building stakeholders to better and easily design, assess and improve the thermal environment of buildings.

This paper aims to present a new one-variable first-order shear deformation theory (OVFSDT) using nonlocal elasticity concepts for buckling of graphene sheets.

Abstract

Purpose

This paper aims to present a new one-variable first-order shear deformation theory (OVFSDT) using nonlocal elasticity concepts for buckling of graphene sheets.

Design/methodology/approach

The FSDT had errors in its assumptions owing to the assumption of constant shear stress distribution along the thickness of the plate, even though by using the shear correction factor (SCF), it has been slightly corrected, the errors have been remained owing to the fact that the exact value of SCF has not already been accurately identified. By using two-variable first-order shear deformation theories, these errors decreased further by removing the SCF. To consider nanoscale effects on the plate, Eringen’s nonlocal elasticity theory was adopted. The critical buckling loads were computed by Navier’s approach. The obtained numerical results were then compared with previous studies’ results using molecular dynamics simulations and other plate theories for validation which also showed the accuracy and simplicity of the proposed theory.

Findings

In comparing the biaxial buckling results of the proposed theory with the two-variable shear deformation theories and exact results, it revealed that the two-variable plate theories were not appropriate for the investigation of asymmetrical analyses.

Originality/value

A formulation for FSDT was innovated by reconsidering its errors to improve the FSDT for investigation of mechanical behavior of nanoplates.

Abstract

Purpose

The study aims to examine the factors affecting the customers' choice of Bangladeshi banks during the Covid-19 pandemic and the moderating effects of private and public banks on this association.

Design/methodology/approach

This study is based on explanatory research, where significant factors have been explored to evaluate the customers' perception of private and public banks in Bangladesh. Primary data are accumulated through an online survey from customers who have an account in a private or public bank in Bangladesh during the past four months, where 318 (non-probability convenience sampling) are usable, and secondary data are collected from various sources. Descriptive statistics, multiple and hierarchical multiple regressions have been conducted.

Findings

The results revealed that customers consider safe and secure websites, infrastructural facilities, technological know-how, service, price, time, payment, administrative and psychological factors in choosing Bangladeshi banks during Covid-19. Moreover, the results show that private and public banks have moderated these associations.

Originality/value

During Covid-19, few studies were conducted on Pakistani, Sri Lankan and Ethiopian banking customers, where different factors are significant; however, this study is unique because all factors are significant for Bangladeshi banking customers. The findings will originate the value with several theoretical implications and managerial guidelines.
