Abstract
In a developing environment, much is being done to provide for safe storage, collection and sanitary disposal of household waste; yet the problem still persists. Examines the ways in which solid waste management is undertaken in Southwest Nigeria and outlines some of the problems encountered. These include the continuous expansion of sprawling areas, funding limitations, variation in eating and waste disposal habits and laxity in enforcing sanitation laws. These and other factors make solid waste management and environmental pollution control in the area extremely complex. Suggestions are made for the recognition of socioeconomic factors in refuse depots siting and management, modification of urban planning management and a well equipped and adequately staffed Waste Disposal Agency.

Abstract
Examines the potential for excessive crop uptake of nutrients, soil mineralization, and response of livestock to the usage of Ogunpa Stream, Ibadan, Nigeria. A number of surface water and soil samples were collected from the Ogunpa and small irrigated farms near the stream for physico‐chemical examination. Results show that the stream is suitable for irrigated agriculture but not for aquaculture and livestock breeding especially in the middle reaches. The added nutrients accumulated in the cultivated layer of the soil. There was some evidence of migration of some elements down from the cultivated layer. The potential hazard for pollution caused by irrigating with the polluted water threatens crop and vegetables grown on adjacent farms as well as groundwater of the nearby area. This may seriously affect the consumers. It is recommended that residents around the stream become aware of how to reduce the pollution level.

Abstract
In this study, characterization of hazardous wastes components, treatment and disposal systems were examined for Southwestern Nigeria. The data were used to assess the effectiveness of monitoring systems and existing regulations on the subject and to proffer solutions for efficient management. Three sources of hazardous wastes were examined, namely: household units, commercial enterprises and industrial outfits. The household units, which were further classified into high, medium and low income earner groups, produced wastes with hazardous components of 5.6 per cent, 4.4 per cent and 4.2 per cent respectively. Typical results also show that the Pb component of wastes from a hairdressing salon, and that from a local aluminium pot making industry, were 0.026ppm and 0.046ppm respectively. Most of the other parameters examined were far higher than limits recommended by the World Health Organisation (WHO) for safe disposal. The trace elements, however, fall within the recommended limit of WHO. The current investigation has stressed the need to: properly monitor industrial wastes discharge as well as environmental protection officials to conduct the test themselves; enforce regulations that might require the installation of treatment plants appropriate for the type of wastes generated; encourage waste reuse and recycling; intensify public education; remediate land already polluted by hazardous waste; divert some profit generated by industries to waste management research; and establish standard laboratories all over the study area for unhindered waste monitoring.

Abstract
Examines the relative nutrient status and public health aspects of six livestock manures when added to soil. Provides analysis of the chemical composition of soils at pig, cattle, goat, rabbit, sheep and poultry waste dump sites and shows a highly significant difference in the level of added nutrients. Draws the conclusion that the observed levels of micronutrients at all waste sites suggest that potential plant toxicity and food chain accumulation problems will be low. Highlights the effect of land application of the manure on human health.

Abstract
Evaluates existing systems of collection and disposal of industrial waste water in the Lagos metropolis, Nigeria. Examines the rate of generation of waste water in the paints, foods and beverages, battery, textile, brewery, and pulp and paper industries. These include among others some selected industries in Ikeja Industrial Estate, Lagos. The cases chosen are believed to give a broad outline of organic strength of industrial wastes as well as disposal problems. Results show biochemical oxygen demand, pH and temperature range of 44‐6000mg/l, 4.5‐9.5 and 30‐40°C respectively. Identifies problems facing industrialists in waste water treatment and disposal. Offers suggestions for minimizing environmental pollution by industrial effluents.

Abstract
Examines rainwater chemistry as it relates to atmospheric pollution in Southern Nigeria. Rainwater samples were collected and analysed for major cations and anions in Lagos, Ibadan and Port Harcourt, these sites reflecting industrial, residential and oil flaring regions respectively. In general, water samples from Ibadan were about neutral. Correlation studies revealed that HCl and H2SO4 dominated the slightly acidic rainwater in the Lagos and Port Harcourt areas respectively. The effect of marine spray from the Gulf of Benin was observed with trace of NaCl. The reaction of the much emitted NH3 with the available SO42– in the atmosphere produced (NH4)2SO4 which acted as a neutralizer for samples from the Lagos area. The findings suggest that rainwater from most industrial cities of Nigeria are tending towards acidity and if oil flaring activities are not checked, there is a tendency of increasing acidic rainwater in the delta regions. The observation and findings are useful for preliminary assessments of the influence of rapid industrial and urban development on atmospheric pollution and indirectly rainwater constituents.

Abstract
Purpose
The purpose of this paper is to validate the consumer styles inventory (CSI) scale for understanding the decision-making styles of shopping app users. The validated scales are used to examine the relationship between consumers’ decision-making styles and factors affecting the use of mobile shopping apps.
Design/methodology/approach
A total of 428 valid responses are collected from the users of the five most popular shopping apps. The mobile shopping apps are selected based on a popularity study. Data are collected from mobile app shoppers through an online survey.
Findings
Findings reveal a new set of factors that can be used for understanding use of mobile shopping apps. Decision-making styles influence the adoption of mobile apps for shopping. Factors responsible for the adoption of mobile shopping apps such as usefulness and risk perceptions differ across consumers with different decision-making styles.
Practical implications
The findings would facilitate online retailers in building focused marketing strategies for segmenting and targeting the consumers having different decision-making styles.
Originality/value
The current research is the first of its kind to examine the applicability of the CSI scale in the context of mobile app shoppers in an emerging economy. The findings enrich the existing literature by providing empirical support to the relationship between decision-making styles and factors affecting adoption of shopping using mobile apps.

Abstract
Purpose
Wireless communication channel provides a wide area of applications in the field of communication, distributed sensor network and so on. The prominence of the wireless communication channel is because of its robust nature and the sustainability for the precise ranging and the localization. The precision and accuracy of the wireless communication channel largely depend on the localization. The development of the wireless communication channel with improved benefits needs the accurate channel model.
Design/methodology/approach
This paper characterizes the tangential path loss model in the WINNER based wireless communication channel model. The measurements taken in the WINNER channel model are compared with the tangential path loss characterized WINNER Channel model.
Findings
The model operates well over the varying antenna orientations, measurement condition and the propagation condition. The proposed tangential path loss model is performing well over the various outdoor scenarios.
Originality/value
The proposed characterization shows change in the small-scale parameters (SSP), such as power, delay, angle of arrival and angle of departure as well as the large-scale parameters (LSP), such as RMS delay spread, shadowing, path loss and Ricean factor associated with the model.

Abstract
Purpose
The purpose of this paper is to investigate the common attributes of brick-and-mortar retail shops liked by young adults in the digitalized retail context. The 7Ps of the marketing mix were used as a framework to shed insights for marketing strategies.
Design/methodology/approach
A qualitative study using personal interviews was designed. A convenience sample of 24 young adults from 20 to 22 years of age was asked to take photos, showing the exterior and interior of their favorite shop in Hong Kong. They were interviewed face to face to explain why they like these shops. Other information about the shopping context, including frequency of visits and whether shopping alone or with friends, was collected.
Findings
The favorite shops of young adults are clothing retailers and stores for snacks. Attributes of favorite shops include stylish product design, variety of choices, cozy physical environment, technology-assisted shopping process and customer-friendly return policy. Young adults seek taste and artistic presentation in consumption. Self-expression and social communication of consumption play a major role in retail brand love.
Research limitations/implications
The sample size of this study was small and may not be generalizable to populations of different socioeconomic status. A quantitative survey can be conducted to further examine the topic.
Practical implications
This study deepens the understanding of how young adults perceive product, store and process attributes of shops that are related to retail brand love. Tangible qualities such as product and physical space played a more important role than intangible attributes such as friendly frontline or sales staff. The results imply that retailers need to pay attention to a shop’s product offering, interior design, as well as develop a seamless integration of online and offline shopping processes to engage customers.
Originality/value
There are very few studies of young consumers and retail brand love using qualitative methods. This study contributes to a deeper understanding of young consumers’ perception of the retail stores that they love in the digitalized retail landscape.
