Perceived price and its effect on product quality, product assortment and customer satisfaction

Abstract: This paper presents a quantitative study investigating the effect of perceived price on product quality and product assortment and the resultant impact on customer satisfaction. A crosssectional data was collected from a convenience sample of shoppers in food retail stores in Johannesburg, South Africa using a self-administered structured questionnaire. A total of 280 questionnaires was returned, yielding an 89.2% response rate which is suitable for multivariate data analysis techniques. The results show a strong effect of product quality on customer satisfaction; customers’ perceptions of price has a strong effect on their evaluation of product assortment. The South African food retailers’ product quality, perceived price and product assortment meet customer needs, with perceived price influencing customers’ evaluation of product assortment by helping customers to find the products they want. This paper contributes to the customer satisfaction literature through investigation of store image attributes which are useful in improving customer satisfaction

Critical Analysis of Strategies Towards Creating an Adequate Level of Awareness on Cybercrime among the Youth in Gauteng Province

This study aims to determine any measures taken by the South African Police Service (SAPS) to create awareness about cybercrime among the youth in the selected policing areas in the Gauteng province. A qualitative research method was applied using semi-structured interviews to find the views of participants, of measures if any, to create youths’ awareness in the area of cybercrime. A total of 37 participants comprised of 29 youths aged between 19 and 35 years, including an additional eight participants from the SAPS Crime Intelligence Unit who agreed to participate. Among these participants, there were 18 females and 19 males. The findings highlighted that there was a lack of awareness on the measures taken by the SAPS in educating the youth about the risks associated with cybercrime. The other challenges highlighted by the SAPS were a lack of capacity, resources, and training to increase the technical skills amongst the SAPS members to work effectively on cybercrime-related challenges, lack of collaboration among role players to respond adequately to cybercrime, and ineffective implementation of cybercrime policies, therefore, there was a lack of cybercrime-related campaigns. Based on the findings, five themes were explored in this study, including a lack of capacity, resources, and training to increase the technical skills amongst the SAPS members to work effectively on cybercrime-related challenges, lack of collaboration among role players to respond adequately to cybercrime and ineffective implementation of cybercrime policies. The recommendations are provided as a potential step towards tailoring education packages and awareness programs to ensure at-risk groups are equipped with actionable mechanisms to protect themselves against cybercrimes

Analysis of aircraft maintenance processes and cost

Abstract: The life cycle of an aircraft consists of design, production, operation and decommissioning phases. For an airline the main focus is on the maintenance process during the operation phase. This paper presents a case study of an airline facing a challenge of increasing maintenance cost. The objective is to understand factors that drive increase in cost. Maintenance cost, flight hours, flight cycles, dispatch reliability and pilot reports were analyzed to find out the maintenance cost drivers. The study identified that the aircraft which dominated the maintenance costs had the highest flight hours, and the lowest dispatch reliability in the fleet

Full-scale trials of external nitrification on plastic media nitrifying trickling filter

The full-scale single-stage tertiary nitrifying trickling filter (NTF) at the Citrusdal Wastewater Treatment Plant provides for external nitrification of unclarified effluent from the facultative aerobic lagoon in order to meet standard effluent ammonia concentration requirements. The apparent ammonia nitrification rate (ApANR, gN/m2 media surface·d) of the NTF was sensitive to particulate organic loading rates which were predominantly in the form of algae, and the soluble COD removal rates increased under cold climates. Installation of forced-air ventilation fans improved the nitrification efficiency from 15% to 43%. An increase in hydraulic loading rate (HLR) by effluent recirculation significantly improved the ApANR, eradicated filter flies and decreased the prevalence of worms. Maximum ApANR of ~1.0 gN/m2·d was achieved yielding an ammonia- removal efficiency of approximately 71%. Profile samples collected along the NTF media depth indicated poor media wetting at low HLR resulting in low ApANR (<0.5 gN/m2·d). Also during the cold and rainy winter period, poor biofilm activity and prevalence of motile algae were observed, and under low hydraulic loading rates and warmer temperatures, a dominance of filter flies and fly larvae were observed. In contrast, in controlled laboratory studies, ApANRs up to 1.72 gN/m2·d (22.1 mgN/l removal) were attained, which, in conformity with full-scale, was also found to be sensitive to hydraulic loading conditions

‘Black like Me’: A Critical Analysis of Arrest Practices Based on Skin Color in the Gauteng Province, South Africa

Objective: This article looks at the everyday life and realities of current practices employed by the South African Police Service (SAPS) officials, by shedding light on the experiences and practices on profiling search and effecting arrest based on race and skin color in the Gauteng Province. Particularly, this article examines the experiences of the SAPS officials to measure police perception of the skin color of foreign nationals, and to establish if wrongful arrests were linked to skin color stereotyping. Methods: The theoretical approach employed the social identity theory (SIT) was used to interpret the results. A survey questionnaire consisting of the New Immigration Survey (NIS) Skin Color Scale with 10 shades of skin color mapped to a pictorial guide, as well as a self-report measure on wrongful arrests, was administered to 80 SAPS officials, who performed visible policing duties. The research sample consisted of two SAPS groups from two different contexts, namely township and urban contexts. The Statistical Package for the Social Sciences (SPSS) software was used to conduct Pearson’s correlation and comparative analyses. Results: The results showed that the SAPS officials stereotyped foreign nationals as dark-skinned. The skin color stereotype was, however, not correlated to wrongful arrests. The study concluded that although respondents perceived that South Africans were distinguishable from foreign nationals based on skin color or tone, identification processes were not influenced by this stereotype belief

Medicinal plant cultivation for sustainable use and commercialisation of high-value crops

Many traditional healing systems are based on natural biological resources, and there is a general shift in most parts of the world towards natural medicine, with direct implications on the demand and supply of medicinal plants. This review highlights the economic importance of medicinal plants, their contribution to healthcare systems, and potential opportunities for rural economic development through cultivation.  A systematic literature review with specific search terms related to medicinal plants was used to collect scientific and non-scientific information from peer-reviewed literature and grey literature databases. The findings indicate that trade in medicinal plants is increasing, and although they are considered minor crops compared to major food crops, their value is among the highest in the list of traded plants globally. The trade also serves as a revenue source for many rural livelihoods, with women playing a significant role. Medicinal plants contribute to primary health care in many developing countries, and they are also an essential source of modern drug discovery. Cultivation of medicinal plants offers emerging rural farmers an opportunity to grow these plants as new and alternative crops, thus reducing unsustainable wild harvesting and competition with established commercial farmers who mostly focus on food crops. Furthermore, medicinal plant cultivation should be promoted as one of the options for local economic development and sustainability through job creation, the revival of the rural economy, and income generation for small businesses, such as the transport businesses, involved in the value chain. Land accessibility, financial resources, and direct market access for rural communities can elevate their contribution to the industry. Formalisation of the lower levels of the medicinal plant trade is also recommended. Significance:• Cultivation is a viable option for biodiversity conservation of medicinal plants and ensuring a goodquality supply of plant materials.• Cultivation of medicinal plants – a source of natural products used in product development – can contribute to job creation, income generation, and rural economies in developing countries.• This review underlines the importance of medicinal plants in product development, the contribution of the industry to economies of different countries, and the potential for cultivation

Nucleation and crystallization in bio-based immiscible polyester blends

Bio-based thermoplastic polyesters are highly promising materials as they combine interesting thermal and physical properties and in many cases biodegradability. However, sometimes the best property balance can only be achieved by blending in order to improve barrier properties, biodegradability or mechanical properties. Nucleation, crystallization and morphology are key factors that can dominate all these properties in crystallizable biobased polyesters. Therefore, their understanding, prediction and tailoring is essential. In this work, after a brief introduction about immiscible polymer blends, we summarize the crystallization behavior of the most important bio-based (and immiscible) polyester blends, considering examples of double-crystalline components. Even though in some specific blends (e.g., polylactide/polycaprolactone) many efforts have been made to understand the influence of blending on the nucleation, crystallization and morphology of the parent components, there are still many points that have yet to be understood. In the case of other immiscible polyester blends systems, the literature is scarce, opening up opportunities in this environmentally important research topic.The authors would like to acknowledge funding by the BIODEST project ((RISE) H2020-MSCA-RISE-2017-778092

THE APPLE DOES NOT FALL FAR FROM THE TREE: CAN SOCIETY CORRUPT POLICE OFFICIALS?

It is argued that police officers commonly present what they consider to be anacceptable face to researchers regarding the cause and extent of police corruptionwithin their respective law enforcement agencies. This ‘self-censorship’ can be achallenge to obtaining a reliable view of police officers’ occupational, informaland personal perceptions. Empirical research on police corruptive practices inSouth Africa highlights the problem which seems to be persistent in the SouthAfrican Police Service (SAPS). Though a number of factors combine to makereliable estimates of the number of officials engaging in misconduct difficult toobtain, the sheer number of individuals working in the SAPS suggest the scope ofthe problem. In order to get beyond some of these familiar tropes given the stigmaattached to corruption, in-depth semi-structured interviews were conducted withkey informants from the public in the three provinces of South Africa namely;Gauteng, KwaZulu-Natal and Western Cape to solicit their views regarding theconcept ‘corrupting society’ as to determine, if society does corrupt the police.The findings indicated that while some pockets of excellence have been attainedtowards improving police-public relations, the other ‘side of the coin’ poses risksto the SAPS as corrupt friendship bonds with friends and associates within thecommunities the police serve, causes profound organisational problems to reducepolice corruption. In the face of recent media scrutiny regarding how at thenational level, some of the former National Commissioners were implicated bythe media to have received kickbacks due to their close associations with someinfluential families, implies a concern of far greater complexity than the ordinaryexchanges of accusation and defence regarding a ‘corrupting society’ and ‘corrupted police officials’ are likely to reveal. The author provided possiblerecommendations emanating from the findings

Evaluation of Trainees’ Post-Training Competency in the South African Police Service

This paper presents the findings on the respondents’ perceptions of trainees’ competency after completing training. A survey was conducted among 329 respondents from 13 police stations in the Johannesburg policing area using a questionnaire. The findings revealed that contextual factors, namely effectiveness, training environment and trainer’s skills as well as adequate resources towards development have a positive impact on the programme conducted at the training centres. Furthermore, the findings highlighted that the respondents were of the view that, since the inception of new methods of training after the 1994 democratic elections, the South African Police Service (SAPS) had demonstrated a progressive development towards responding to community matters. However, there were gaps in the training and development programmes such as lack of resources, the blanket approach to training and the training models focusing on current challenges rather than future trends. To address these challenges within the SAPS and ensure that there is effective training and development for organisational performance, there is a need to ensure that there are adequate resources for training and development. The training and development procedures within the SAPS also need to adopt international standards. The management at the Johannesburg Training Centre also needs to come up with an effective strategy to identify the needs and skills gaps of employees and ensure that these are addressed in an ever-changing and improving training and development strategy. This study provides critical input and makes a contribution to the literature related to training in the SAPS in South Africa
