The effect of national culture on customer satisfaction in call centres across national borders

Kotze, Theo 09 March 2013 (has links)
Characteristics of national cultures have frequently been claimed to influence service quality perception and customer satisfaction. This inquiry investigates this claim by analysing a multinational company’s call centre servicing two markets across national borders. Hypotheses are derived which relate the cultural and customer characteristics of age, gender and socio-economic status to customer satisfaction and perceived service quality within each country.Using multiple regression and CHAID models as well as Mann-Whitney and Kruskal-Wallis tests, the hypotheses are tested by analysing call centre service feedback data on 245 customers in the South African and 201 customers in the British market. Empirical support for the effect of national culture on perceived service quality and customer satisfaction is found.Empirical proof that females report higher levels of satisfaction than males is found while the importance customers place on service quality constructs are proven to vary by age and gender. A call centre management model integrating culture and customer characteristics, which provides a richer perspective of the mechanics of value creation, is suggested. / Dissertation (MBA)--University of Pretoria, 2012. / Gordon Institute of Business Science (GIBS) / unrestricted

A National Study of Colorectal Cancer Survivorship Disparities: A Latent Class Analysis Using SEER (Surveillance, Epidemiology, and End Results) Registries

Montiel Ishino, Francisco A., Odame, Emmanuel A., Villalobos, Kevin, Liu, Xiaohui, Salmeron, Bonita, Mamudu, Hadii, Williams, Faustine 25 February 2021 (has links)
Introduction: Long–standing disparities in colorectal cancer (CRC) outcomes and survival between Whites and Blacks have been observed. A person–centered approach using latent class analysis (LCA) is a novel methodology to assess and address CRC health disparities. LCA can overcome statistical challenges from subgroup analyses that would normally impede variable–centered analyses like regression. Aim was to identify risk profiles and differences in malignant CRC survivorship outcomes. Methods: We conducted an LCA on the Surveillance, Epidemiology, and End Results data from 1975 to 2016 for adults ≥18 (N = 525,245). Sociodemographics used were age, sex/gender, marital status, race, and ethnicity (Hispanic/Latinos) and stage at diagnosis. To select the best fitting model, we employed a comparative approach comparing sample-size adjusted BIC and entropy; which indicates a good separation of classes. Results: A four–class solution with an entropy of 0.72 was identified as: lowest survivorship, medium-low, medium-high, and highest survivorship. The lowest survivorship class (26% of sample) with a mean survival rate of 53 months had the highest conditional probabilities of being 76–85 years–old at diagnosis, female, widowed, and non-Hispanic White, with a high likelihood with localized staging. The highest survivorship class (53% of sample) with a mean survival rate of 92 months had the highest likelihood of being married, male with localized staging, and a high likelihood of being non-Hispanic White. Conclusion: The use of a person–centered measure with population-based cancer registries data can help better detect cancer risk subgroups that may otherwise be overlooked.

Feasibility of Utilizing Social Media to Promote HPV Self‐Collected Sampling Among Medically Underserved Women in a Rural Southern City in the United States (U.S.)

Asare, Matthew, Lanning, Beth A., Isada, Sher, Rose, Tiffany, Mamudu, Hadii M. 01 October 2021 (has links)
Background: Social media (Facebook, WhatsApp, Instagram, Twitter) as communication channels have great potential to deliver Human papillomavirus self‐test (HPVST) intervention to medically underserved women (MUW) such as women of low income. However, little is known about MUW’s willingness to participate in HPVST intervention delivered through social media. We evaluated factors that contribute to MUW’s intention to participate in the social media‐related intervention for HPVST. Methods: A 21‐item survey was administered among women receiving food from a local food pantry in a U.S. southern state. Independent variables were social media usage facilitators (including confidentiality, social support, cost, and convenience), and barriers (including misinformation, time‐consuming, inefficient, and privacy concerns). Dependent variables included the likelihood of participating in social‐driven intervention for HPVST. Both variables were measured on a 5‐point scale. We used multinomial logistic regression to analyze the data. Results: A total of 254 women (mean age 48.9 ± 10.7 years) comprising Whites (40%), Hispanics (29%), Blacks (27%), and Other (4%) participated in the study. We found that over 44% of the women were overdue for their pap smears for the past three years, 12% had never had a pap smear, and 34% were not sure if they had had a pap smear. Over 82% reported frequent social media (e.g., Facebook) usage, and 52% reported willingness to participate in social media‐driven intervention for HPVST. Women who reported that social media provide privacy (Adjusted Odds Ratio (AOR) = 6.23, 95% CI: 3.56, 10.92), provide social support (AOR = 7.18, 95% CI: 4.03, 12.80), are less costly (AOR = 6.71, 95% CI: 3.80, 11.85), and are convenient (AOR = 6.17, 95% CI: 3.49, 10.92) had significantly increased odds of participating in social media intervention for HPVST. Conclusions: The findings underscore that the majority of the MUW are overdue for cervical cancer screening, regularly use social media, and are willing to participate in social media‐driven intervention. Social media could be used to promote HPV self‐testing among MUW.

Racial Associations Between Gambling and Suicidal Behaviors Among Black and White Adolescents and Young Adults

Ahuja, Manik, Werner, Kimberly B., Cunningham-Williams, Renee M., Bucholz, Kathleen K. 01 June 2021 (has links)
Purpose of Review: Suicide is the second leading cause of death among Black youth ages 10–19 years. Between 1991 and 2017, rates of suicide among Black youth have been increasing faster than rates among any other race/ethnic group. There are many factors that may explain this increase, with gambling being suggested as one such potential risk factor. This review examines the association between gambling and suicide behaviors, and how these associations may vary between Black and White youth and young adults. The current review examines these associations using data from the Missouri Family Study (MOFAM). Recent Findings: Recent findings have revealed distinct patterns of substance use initiation and gambling behaviors between Black youth and White youth. While strong links between gambling and suicide behaviors have also been reported, whether the associations were consistent across race/ethnicity groups was not investigated, nor in these cross-sectional analyses was it possible to determine whether the gambling behaviors preceded or followed suicidality. Thus, there is a need to investigate whether there are differences in the associations of gambling and suicide behaviors at the race/ethnicity level in tandem with data that examine the sequence of the behaviors. The current report focuses on racial/ethnic differences using data that allow for sequencing the occurrence of the behaviors via the age of first gambling experience, and of first suicidal symptom, to better distinguish the nature of the association. Summary: The current findings revealed that gambling initiation predicted suicide ideation among Black youth, while no significant association was found among White youth. This is of major public health concern, given the rising rates of suicide among Black youth, and the increased availability of gambling. The report did not find a link between gambling and suicide attempts. Culturally tailored interventions should be considered among schools, families, and clinicians/providers, to highlight the risk of adolescent gambling, particularly among Black youth.

Barriers to Dissemination of Local Health Data Faced by US State Agencies: Survey Study of Behavioral Risk Factor Surveillance System Coordinators

Ahuja, Manik, Aseltine, Robert, Jr. 01 July 2021 (has links)
Background: Advances in information technology have paved the way to facilitate accessibility to population-level health data through web-based data query systems (WDQSs). Despite these advances in technology, US state agencies face many challenges related to the dissemination of their local health data. It is essential for the public to have access to high-quality data that are easy to interpret, reliable, and trusted. These challenges have been at the forefront throughout the COVID-19 pandemic. Objective: The purpose of this study is to identify the most significant challenges faced by state agencies, from the perspective of the Behavioral Risk Factor Surveillance System (BRFSS) coordinator from each state, and to assess if the coordinators from states with a WDQS perceive these challenges differently. Methods: We surveyed BRFSS coordinators (N=43) across all 50 US states and the District of Columbia. We surveyed the participants about contextual factors and asked them to rate system aspects and challenges they faced with their health data system on a Likert scale. We used two-sample t tests to compare the means of the ratings by participants from states with and without a WDQS. Results: Overall, 41/43 states (95%) make health data available over the internet, while 65% (28/43) employ a WDQS. States with a WDQS reported greater challenges (P=.01) related to the cost of hardware and software (mean score 3.44/4, 95% CI 3.09-3.78) than states without a WDQS (mean score 2.63/4, 95% CI 2.25-3.00). The system aspect of standardization of vocabulary scored more favorably (P=.01) in states with a WDQS (mean score 3.32/5, 95% CI 2.94-3.69) than in states without a WDQS (mean score 2.85/5, 95% CI 2.47-3.22). Conclusions: Securing of adequate resources and commitment to standardization are vital in the dissemination of local-level health data. Factors such as receiving data in a timely manner, privacy, and political opposition are less significant barriers than anticipated.

The Progress of Tobacco Control Research in Sub-Saharan Africa in the Past 50 Years: A Systematic Review of the Design and Methods of the Studies

Mamudu, Hadii M., Subedi, Pooja, Alamin, Ali E., Veeranki, Sreenivas P., Owusu, Daniel, Poole, Amy, Mbulo, Lazarous, Ogwell Ouma, A. E., Oke, Adekunle 01 December 2018 (has links)
Over one billion of the world’s population are smokers, with increasing tobacco use in low-and middle-income countries. However, information about the methodology of studies on tobacco control is limited. We conducted a literature search to examine and evaluate the methodological designs of published tobacco research in Sub-Saharan Africa (SSA) over the past 50 years. The first phase was completed in 2015 using PubMed, Embase, CINAHL, and Cochrane Central Register of Controlled Trials. An additional search was completed in February 2017 using PubMed. Only tobacco/smoking research in SSA countries with human subjects and published in English was selected. Out of 1796 articles, 447 met the inclusion criteria and were from 26 countries, 11 of which had one study each. Over half of the publications were from South Africa and Nigeria. The earliest publication was in 1968 and the highest number of publications was in 2014 (n = 46). The majority of publications used quantitative methods (91.28%) and were cross-sectional (80.98%). The commonest data collection methods were self-administered questionnaires (38.53%), interviews (32.57%), and observation (20.41%). Around half of the studies were among adults and in urban settings. We conclud that SSA remains a “research desert” and needs more investment in tobacco control research and training.

Sociodemographic and Geographic Disparities of Prostate Cancer Treatment Delay in Tennessee: A Population-Based Study

Montiel Ishino, Francisco A, Odame, Emmanuel A, Villalobos, Kevin, Rowan, Claire, Whiteside, Martin, Mamudu, Hadii, Williams, Faustine 01 November 2021 (has links)
The relationship of social determinants of health, Appalachian residence, and prostate cancer treatment delay among Tennessee adults is relatively unknown. We used multivariate logistic regression on 2005-2015 Tennessee Cancer Registry data of adults aged ≥18 diagnosed with prostate cancer. The outcome of treatment delay was more than 90 days without surgical or nonsurgical intervention from date of diagnosis. Social determinants in the population-based registry were race (White, Black, Other) and marital status (single, married, divorced/separated, widow/widower). Tennessee residence was classified as Appalachian versus non-Appalachian (urban/rural). Covariates include age at diagnosis (18-54, 54-69, ≥70), health insurance type (none, public, private), derived staging of cancer (localized, regional, distant), and treatment type (non-surgical/surgical). We found that Black and divorced/separated patients had 32% (95% confidence interval [CI]: 1.22-1.42) and 15% (95% CI: 1.01-1.31) increased odds to delay prostate cancer treatment. Patients were at decreased odds of treatment delay when living in an Appalachian county, both urban (odds ratio [OR] = 0.89, 95% CI: 0.82-0.95) and rural (OR = 0.83, 95% CI: 0.78-0.89), diagnosed at ≥70 (OR = 0.59, 95% CI: 0.53-0.66), and received surgical intervention (OR = 0.72, 95% CI: 0.68-0.76). Our study was among the first to comprehensively examine prostate cancer treatment delay in Tennessee, and while we do not make clinical recommendations, there is a critical need to further explore the unique factors that may propagate disparities. Prostate cancer treatment delay in Black patients may be indicative of ongoing health and access disparities in Tennessee, which may further affect quality of life and survivorship among this racial group. Divorced/separated patients may need tailored interventions to improve social support.

Gender Discrimination and Illicit Drug Use Among African American and European American Adolescents and Emerging Adults

Ahuja, Manik, Haeny, Angela M., Sartor, Carolyn E. E., Bucholz, Kathleen K. 01 January 2021 (has links)
Objective: The present study aimed to characterize the association of perceived gender discrimination and illicit drug use among a sample of African American (AA) and European American (EA) adolescent girls and young women. Method: Data were drawn from a high-risk family study of alcohol use disorder of mothers and their offspring (N = 735). Multinomial regressions were used to examine whether experience of offspring and maternal gender discrimination were associated with offspring illicit drug use (cannabis, cocaine, ecstasy, PCP, opiates, hallucinogens, solvents, sedatives, or inhalants). Outcomes included offspring age of drug use initiation (age ≤ 14) and lifetime heavy drug use (≥ 50 times) of 1 or more illicit substances. Interactions between race and offspring gender discrimination were modeled to assess for race differences. Results: Results revealed that gender discrimination was associated with a greater likelihood of offspring early initiation (relative risk ratio [RRR] = 2.57, 95% CI [1.31, 5.03]) versus later initiation (RRR = 1.33, 95% CI [0.80, 2.24]). Offspring gender discrimination was associated with offspring heavy drug use (RRR = 2.09, 95% CI [1.07, 4.06]) and not associated with moderate/light use (RRR = 1.44, 95% CI [0.86, 2.42]), but post hoc tests revealed no significant group differences. Conclusions: Findings suggest that perceived offspring gender discrimination is associated with early drug use initiation. Gender discrimination, particularly at an early age, has a potential to cause harm, including drug use. Implementation of policies that foster environments that eliminate gender bias and discrimination at an early age should be prioritized. Gender-responsive treatment merits consideration by substance use treatment providers. Public Significance Statement: This study indicates that adolescent females who experience gender discrimination, are more likely to initiate drugs at an earlier age. Targeting gender discrimination during adolescence may be important, before gender norms become rooted into one’s trajectory.

Fractional Flow Reserve Using Computed Tomography for Assessing Coronary Artery Disease: A Meta-Analysis

Panchal, Hemang B., Veeranki, Sreenivas P., Bhatheja, Samit, Barry, Neil, Mahmud, Ehtisham, Budoff, Matthew, Lavine, Steven J., Mamudu, Hadii M., Paul, Timir K. 01 January 2016 (has links)
Aims: Noninvasive fractional flow reserve (FFR) measurement with computed tomography (FFRCT) is a newly described method for assessing functional significance of coronary disease. The objective of this metaanalysis is to determine the diagnostic performance of FFRCTin the assessment of hemodynamically significant coronary artery stenosis. Methods: PubMed and the Cochrane Center Register of Controlled Trials were searched from January 2000 through February 2015. Six original studies were found comparing FFRCTto invasive FFR in evaluating hemodynamic significance of coronary lesions (1354 vessels; 812 patients). Lesions were considered hemodynamically significant if invasive FFR was 0.80 or less. FFRCTused the same cutoff as invasive FFR to be considered as a positive test. Sensitivity, specificity, positive and negative likelihood ratios, and diagnostic odds ratio were calculated. Results: One-third of the lesions (n=443) were hemodynamically significant. The pooled per-vessel analysis showed that the sensitivity, specificity, negative and positive likelihood ratios, and diagnostic odds ratio of FFRCTto diagnose hemodynamically significant coronary disease were 0.84 [95% confidence interval (CI):0.80-0.87], 0.76 (95% CI: 0.73-0.79), 0.22 (95% CI: 0.17-0.29), 3.48 (95% CI: 2.21-5.47), and 16.82 (95% CI: 8.20-34.49), respectively. Conclusion: The results of this meta-analysis demonstrate that FFRCTresults correlate closely with invasive coronary angiography and FFR measurement. It is a feasible noninvasive method to assess hemodynamic significance of coronary lesions in patients with stable coronary artery disease.
