Premium customers' perception of firms' customer relationship management segmentation, identity strategies and their satisfaction

Abstract: This paper examines premium customers' perception of CRM segmentation strategies of firms and how their identity and satisfaction are taken into account by Nigerian mobile telecommunications firms. The qualitative phenomenology interview strategy was chosen for this study. Twelve interviews were conducted and data were analysed using content and thematic techniques with NVivo 11. Findings show that personality and economic identities were the variables most taken into consideration by firms for implementing their CRMS [CRMS]. These identities affect firms' CRMS strategy based on customer lifetime value. The study also revealed that CRM affect both identities and premium CSAT, although quality of service showed higher impact than price and trust on satisfaction. Six themes affect experiences of respondents. This study extends the value of social identity theory (SIT) and rationality choice theory (RCT) in CRMS. The practical implication suggests profitable and competitive opportunities for firms to improve premium CSAT.

Strategies to Mitigate the Impact of COVID-19 on Food Security and Malnutrition in Nigeria

Abstract: As a developing nation and the most populous nation in Africa, Nigeria has faced challenges associated with meeting the food needs of its expanding population over the years. This is due to the nation transitioning from a net exporter of foods to being dependent on food imports, leading to many people suffering from stunting and severe malnourishment. The COVID-19 pandemic has compounded this food insufficiency within the country with its attendant global impacts. The restrictions in the movement of people and goods in the country, due to the current pandemic, have affected access to food and agricultural input, heavily affecting the financial ability of families. This Short Communication Onyeaka et al.; EJNFS, 13(2): 103-109, 2021; Article no.EJNFS.66864 104 mini-review highlights the impact of COVID-19 on the country's nutritional status, the rising incidence of food insecurity and proposes approaches that can be employed to mitigate these adverse effects. Approaches to improving food security and the nutritional status of the country during the pandemic and post-pandemic era will involve deliberate policies of the government which focuses on increasing funding to local food producers, lifting restrictions on the transport of food commodities, encouraging markets for the retail of locally produced foods and more importantly instituting nutritional intervention programmes for children and the vulnerable within the community.

Self-Serving Attributions in Teachers' Explanations of Students' Performance in a National Oral Essay Competition

Abstract: The purpose of the study was to determine the influence of self-serving and ingroup-outgroup biases on teachers' attributions and evaluation of students' performances. The participants were 51 senior secondary school students whose performances in an oral essay competition were evaluated by a panel of 5 judges. After the competition, the teachers were asked to make attributions of their students' performances in the competition. The findings revealed that the teachers of the successful students attributed the success to internal factors while the teachers of the unsuccessful students attributed the students' failures to external factors. It was concluded that self-serving and ingroup-outgroup biases influenced the teachers' attributions and judgment of their students' performances.

Antifungal Action of Garlic (Allium sativum) and Ginger (Zingiber officinale) on Some Pathogenic Fungi

Abstract: Background: The antifungal activities of fresh garlic (Allium sativum) and ginger (Zingiber officinale) on the growth of three known pathogenic fungi were investigated. The test organisms were Aspergillus spp Penicillium spp and Candida albicans. Methodology: Two different concentrations of extracts were used. Concentration I which had crude extract of 100 g/ 100 ml of sterile distilled water and concentration II with extract of 100 g/50 m1 of distilled water. Ten mls of each extract was added to each 125 m1 of SAB (saboraud dextrose agar) media before and after sterilization. Results: The extracts added to the media after its sterilization inhibited the growth of the pathogenic fungi samples more than the extracts added to the media before sterilization. This indicates that the active ingredients present in the extracts which have the antifungal effect observed is negatively affected and inactivated at 121ºC for 15 minutes. It can be inferred that garlic and ginger have different levels of therapeutic values on fungi.

Seroepidemiology of Transfusion Transmissible Viral Infection among University Fresh Students in Port Harcourt, Nigeria

Abstract: Results: Prevalence rates of 1.7%, 2.1%, and 0.1% were obtained for HIV, HBV, and HCV, respectively. A breakdown of HIV prevalence gave HIV-1 (1.1%), HIV-2 (0.27%), and HIV-1 /2 (0.33%). From the 1,500 subjects tested, 357 (23.8%) belong to the Ijaw, 408 (27.2%) to Ikwerre, 201(13.4%) to Ogoni/Eleme, 75 (5.0%) Ekpeye and 459(30.6%) belong to the other ethnic groups. Other ethnic groups accounted for the highest prevalence of HIV and HBsAg. Youths aged 21 to 30 constituted the highest number of HIV and hepatitis infections. Of the 23 subjects positive for HIV, 16 (1.2%) had HIV-1, 4 (0.3%) had HIV-2, and 5 (0.5%) had the HIV-1/2. Of the 1,500 subjects tested, 0.2% had HIV and HBV co-infection. Chi-square analysis indicated that age was a risk factor for the transmission of the three transmissible infections (P < 0.01, P < 0.05, and P < 0.05 for HIV, HBsAg, and HCV, respectively). Gender had an influence on HIV and HBsAg (P < 0.05). There was also a positive association between the ethnic groups and the TTIs (χ2 = 18.136, P < 0.01 for HIV; χ2 = 2.785, P < 0.05 for HBsAg; and χ2 = 2.411, P < 0.05 for HCV). The 0.1% prevalence of HCV in this study occurred exclusively among nonnatives. Conclusions: This study has provided epidemiological data on some transfusion-transmissible viral infections in Port Harcourt and has identified some risk factors associated with it. To ensure safety in blood-transfusion practices, selection and screening of donors within the high-risk groups, especially individuals 21 to 30 years old, should be thorough and in accordance with the approved safety guidelines.
