Abstract

A study was designed to investigate the chemical coagulation process for the treatment of the potato food industry wastewater of the “Chipsy factory” located at Abi‐Sier, Egypt. The chemical coagulants used in the study include alum, ferric chloride, calcium chloride, ferric sulphate and Nalco as polymer. Variable doses of these coagulants were examined to determine the optimum dose. Results obtained showed that chemical treatment (coagulation, flocculation, followed by sedimentation) was efficient to reduce the chemical oxygen demand (COD), total suspended solids (TSS) and turbidity significantly. Remarkable variation of the removal efficiency depends on the type of coagulant. Ferric chloride and ferric sulphate were more efficient than calcium chloride. Combination of Nalco with each of the studied coagulants improved the removal efficiency remarkably. Reduction of 91‐94 per cent of turbidity, 93‐97 per cent of COD, and 94‐97 per cent of the TSS was achieved with these combinations.

Abstract

Purpose

The purpose of this paper is to explore how ownership concentration affects cost of debt (CoD) in one of the most important emerging markets in the Middle East and North Africa, Morocco.

Design/methodology/approach

The study employs panel data analysis using non-financial firms listed on Casablanca Stock Exchange (CSE) between 2004 and 2016. To unveil the hidden facets of the relationship between ownership concentration and CoD, and examine if this relationship changes with market conditions, we conduct a pre–post-crisis analysis.

Findings

The results demonstrate that controlling shareholders promote decent governance as long as they are able to generate appropriate returns. However, this behavior seems to change during the post-crisis period. In their attempts to increase their returns adversely affected by the financial crisis, controlling shareholders switch from guardians of decent governance and firm’s resources to a menace to creditors’ interests.

Practical implications

Our results expose the severity of agency problems in CSE. It is the duty of all market participants including regulators, board of directors, financial analysts, shareholders and creditors to scrutiny and reinforce governance mechanisms to alleviate expropriation by controlling shareholders. Improving country and firm-level governance mechanisms would enhance investors’ protection, attract international investors and boost the economic activity.

Originality/value

Prior research is inconclusive about the impact of ownership concentration on CoD. Hence, it is worthwhile to seek new evidence in a new market on the nature of this relationship.

Abstract

This article presents the results of a survey of 250 Canadian male consumers. In this study consumer judgements of products made in both highly and newly industrializing countries were obtained in a multi‐attribute and multidimensional context. The results show that younger and less affluent respondents react more favorably towards products made in newly industrializing East Asian countries. The country‐of‐origin image of East Asian countries is less negative for products that generate a medium level of involvement (e.g., a VCR). This negative image of East Asian countries is attenuated by providing other product‐related information to consumers such as brand name and warranty. East Asian countries are perceived more negatively as countries of design than as countries of parts and assembly. In comparison with products made in highly developed countries, products made in East Asia are perceived to be poorer in terms of performance, quality and originality but more economical.

Abstract

Examines the treatability of highly polluted wastewater from a dairy factory prior to its final disposal into the public sewerage system. Physical treatment of the dairy waste via aeration, followed by settling, resulted in a 25 per cent chemical oxygen demand (COD) reduction and elimination of odours. Chemical treatment achieved almost 50 per cent removal of COD. The chemical‐biological process using activated sludge/trickling filter resulted in 64 per cent and 90 per cent removal of the volatile organic matter value respectively. However, the quality of the waste produced does not meet with the National Regulatory Standards for wastewater disposal into the sewerage system. Chemical‐biological treatment using an upflow anaerobic reactor succeeded in reducing the pollutional parameters to coincide with the limits of the Egyptian Law 93/1962 and produces biogas as a source of energy at a rate of 0.39m3/kg COD removed.

Abstract

A study to determine the effectiveness of PAC on the removal of COD and colour from dye wastewater. Factors affecting treatment efficiency were investigated and included PAC particle sizes, initial dye concentration and contact time. The adsorption parameters for Langmuir, Freundlich and Dziubek′s isotherms were determined. Results indicated that a very short contact time of one hour was needed to reach equilibrium of adsorption. A COD (chemical oxygen demand) removal efficiency of 90 per cent for disperse‐red‐60 dye wastewater was obtained with PAC (powdered activated carbon). With PAC dosage of less than 15g/l the adsorption followed both Freundlich′s and Langmuir′s isotherms. The ultimate capacity of the adsorption increased with decreasing PAC particle sizes or the initial dye concentration. The mass transfer coefficient was determined in this study.

Abstract

Purpose

The purpose of this paper is to report on the success of an initiative involving the transformation of a group of small substance use treatment only or mental health treatment only provider agencies serving uninsured adults into providers of co-occurring disorder treatment.

Design/methodology/approach

The paper uses a case study narrative to describe the initiative and the transformation of the participant agencies from being providers of mental health or substance use treatment to providers of co-occurring disorders.

Findings

Six agencies serving uninsured adults expanded their scope of patient treatment services to include the capacity to treat adults with co-occurring disorders. This was achieved with modest support funding from a local foundation. The initiative has been ongoing for five years.

Practical implications

The outcome of this initiative demonstrates the financial and practical feasibility of improving and expanding treatment services to low-resourced patient populations. The participating agencies were able to improve their capacity to treat patients with substance use or mental health issues that previously they were not prepared to treat and thus increased their ability to provide integrated care.

Originality/value

The initiative described here shows that the treatment of concomitant substance use and mental health disorders is within the range of many small-scale treatment providers, if provided the leadership and support. Delivery of effective treatments to populations experiencing co-occurring disorders that are underserved and undertreated are achievable in community-based clinical practices. This has implications for developing treatment capacity outside of hospital settings to enable treatment of co-occurring disorders to become more accessible.

Abstract

Purpose

Pakistan is predominantly a cash-based economy, with consumers showing several traits ranging from low confidence on the electronic commerce security, poor access to banking, absence of widespread awareness of e-payments and other religious and psychological barriers to adopting alternatives to cash. This study aims to examine e-payment modes in Pakistan with respect to their impact on supplier and consumer behaviour before and during the pandemic times.

Design/methodology/approach

The research follows a qualitative approach. Focus groups and interviews are conducted to carry out an in-depth analysis of consumer and supplier behaviour.

Findings

The findings show that customers are not satisfied with the current e-commerce system in Pakistan, whereas though producers prefer prepayments, they are forced to rely on cash on delivery. However, due to the recent COVID-19 outbreak, consumers are going cashless to avoid physical cash and observe safety protocols. To convert this temporary and enforced patronage of online transactions into a long-term and sustainable one, massive marketing and a combined effort from the government, private bodies and financial institutions is required.

Research limitations/implications

The study was conducted using online interviews which has the drawback of connection issues, delays and lags in the connectivity, and hence may lead to miss important gestures for data analysis.

Originality/value

This research can be of benefit to online consumers and the supplier side of the online retail industry, by providing them with insight into the various factors that affect consumer behaviour towards e-commerce payment options. An understanding of the behavioural motivators of consumers will allow e-retailers in developing more marketing strategies that are effective, to improve the satisfaction level of their customers and contribute to the development of Pakistan’s e-commerce sector into a globally competitive one.

Abstract

Purpose

This study aims to explore suitable anode materials used in the electrochemical system for indigo dyeing wastewater, to achieve optimal treatment performances.

Design/methodology/approach

The single factor experiment was used to explore the optimum process parameters for electrochemical decolorization of indigo dyeing wastewater by changing the applied voltage, electrolysis time and electrolyte concentration. At the voltage of 9 V, the morphology of flocs with different electrolytic times was observed and the effect of electrolyte concentration on decolorization rate in two electrolyte systems was also investigated. Further analysis of chemical oxygen demand (COD) removal rate, anode weight loss and sediment quantity after electrochemical treatment of indigo dyeing wastewater were carried out.

Findings

Comprehensive considering the decolorization degree and COD removal rate of the wastewater, the aluminum electrode showed the best treatment effect among several common anode materials. With aluminum electrode as an anode, under conditions of applied voltage of 9 V, electrolysis time of 40 min and sodium sulfate concentration of 6 g/L, the decolorization percentage obtained was of 94.59% and the COD removal rate reached at 84.53%.

Research limitations/implications

In the electrochemical treatment of indigo dyeing wastewater, the aluminum electrode was found as an ideal anode material, which provided a reference for the choice of anodes. The electrodes used in this study were homogenous material and the composite material anode needed to be further researched.

Practical implications

It provided an effective and practical anode material choice for electrochemical degradation of indigo dyeing wastewater.

Originality/value

Combined with the influence of applied voltage, electrolysis time and electrolyte concentration and anode materials on decolorization degree and COD removal rate of indigo dyeing wastewater, providing a better electrochemical treatment system for dyehouse effluent.

Abstract

Purpose

The purpose of this study is to propose a unified model to connect the three subcomponents of the country of origin (COO) with price, quality and consumer perceptions of or intentions regarding a product. COO refers to the country with which a manufacturer’s product or brand is associated. COO can be broken down into three subcomponents: the country of design, the country of assembly and the country of parts.

Design/methodology/approach

This study reviews the COO research that has been conducted in recent decades. These studies have primarily examined the correlation of COO’s broken-down components with marketing factors (such as price, quality and brand equity or loyalty) and consumer purchase behavior. These correlations are portrayed in a single model. This theory-building model is drawn using a philosophical conceptualization approach.

Findings

This study concludes that, as a result of globalization and advancement in technology, consumers are more aware of and have more access to product/brand information, and they evaluate brands according to the COO and its subcomponents. Variables such as price and quality are of high importance and should be considered during a purchase decision, whereas brand equity/loyalty is of low importance.

Research limitations/implications

This research requires further investigation, especially in developing countries, to develop a more comprehensive picture. In addition, not all marketing factors are incorporated in the model.

Practical implications

When international marketers devise plans to serve consumers, they must consider differentiation between developed and developing nations from the point of COO subcomponents and their effects on purchase intentions and consumer evaluations, when moderated by price, quality and brand loyalty/equity.

Originality/value

Prior to this study, no unified model had been proposed to connect the three subcomponents of COO with price, quality and consumer perceptions of or intentions regarding a product.

Abstract

Purpose

This paper aims to investigate the effects of country‐of‐manufacture (COM) and country‐of‐design (COD) on industrial brand equity.

Design/methodology/approach

A conceptual framework to assess how international buyers evaluate industrial brand equity when confronted with a single cue and multiple cues is proposed. Data for testing the hypotheses are collected through fax, e‐mail, and online surveys of managers from 102 industrial buyers of Taiwanese fasteners. A quantitative study is undertaken of 64 respondents using PLS analysis.

Findings

The main finding is that the single‐cue framework produces more statistically significant COM and COD effects on industrial brand equity than does the multiple‐cue framework. The current results confirm previous findings that the country‐of‐origin effects based on single‐cue and multiple‐cue studies produce conflicting and inconclusive results.

Research limitations/implications

These findings underscore the findings that the impacts of COM and COD on industrial brand equity are jointly determined by study characteristics, research designs, and the nature of the dependent variable being investigated.

Practical implications

A clear implication for managers responsible for branding and communicating B2B products in international markets is to continue to create clear awareness of the offering and to provide appropriate imagery for consolidating the reputation of firms in both their internal (product) and external (country‐of‐origin) dimensions.

Originality/value

While country‐of‐origin and consumer products have been widely studied in the literature, the paper examines the effects of COM and COD on industrial brand equity in analyzing the process by which international buyers evaluate brand equity when confronted with a single cue and multiple cues.
