Factors affecting consumers’ intention towards purchasing halal food in South Africa: a structural equation modelling

This research study highlighted the factors that influence the intention of consumers to buy halal food products. In this study, the researchers have chosen to address the gap in the literature pertaining to non-South African consumers’ purchase intention. Non-South Africans are foreign people who reside in South Africa including immigrants, workers, and students. Through utilising the theory of planned behaviour, this study aims to determine the attitudes, subjective norms, perceived behaviour control, and awareness of non-South African towards purchasing halal food products. This also attempts to identify the strongest factor that influences the purchasing intention of halal food by non-South African consumers. The sample of the study consisted of 230 non-South African consumers in Cape Town. Data were collected through self-administered questionnaires. Structural equation modelling (SEM) was used to identify the structural relationships among the constructs identified and to test the study hypotheses. The findings of this study indicate that there is a significant relationship between awareness and buying behaviour. Interestingly it found that only the attitude dimension of TPB had a significant relationship with purchase intention, whereas subjective norms and perceived behavioural control did not show a significant relationship with the consumer intention variable.     

Public Revenue‐Expenditure Nexus in South Africa: Are there Asymmetries?

This paper re‐examines the government revenue and expenditure relationship in South Africa using Enders and Siklos' Threshold adjustment and Granger causality tests. The paper allows for structural breaks in the unit root and cointegration tests. The results indicate the absence of any asymmetries in both the threshold autoregression and momentum threshold autoregression specifications of adjustments in the South African's budgeting process. The estimated symmetric error‐correction models provide support for the fiscal synchronization hypothesis of government revenues and expenditures for long‐run and short‐run dynamic equilibrium. These findings indicate that the South African fiscal authorities should try to maintain or even improve the control of their fiscal policy instruments to sustain the prudent budgetary process.     

Overall survival,costs, and healthcare resource use by line of therapy in Medicare patients with newly diagnosed metastatic urothelial carcinoma

Aims: Medicare patients with metastatic or surgically unresectable urothelial carcinoma (mUC) often receive platinum-based chemotherapy as first line of therapy (LOT), but invariably progress, requiring additional LOTs and healthcare resource use (HCRU). To better understand the evolving mUC treatment landscape, the economic burden of chemotherapy-based mUC treatments among US Medicare patients was estimated.

Methods: Newly diagnosed Medicare patients with mUC were identified from the Surveillance, Epidemiology, and End Results (SEER)-Medicare database. Patients were followed from diagnosis to death, disenrollment, or end of study to characterize LOTs (first [LOT1], second [LOT2], and third or greater [LOT3+]). Kaplan-Meier methods were used to estimate overall survival (OS) by LOT. HCRU and mean costs were reported over the follow-up period, LOT duration, and maximum LOT received.

Results: Among 1,873 eligible patients with mUC (median age?=?77?years; median follow-up?=?7.5?months), 1,035 (55%) received no chemotherapy. Among chemotherapy-treated patients, 61% had LOT1 only, 25% had LOT1 and LOT2 only, and 14% had LOT3+. Median OS was 8.1?months, range was 4.3 (untreated) to 29.8 (LOT3+) months. HCRU frequency increased with additional LOTs. Mean cumulative per-patient cost was $82,912 for all patients, increasing with additional LOTs (untreated?=?$57,207; LOT1?=?$99,213; LOT2?=?$125,190; LOT3+?=?$163,884). Mean per patient per month cost was $18,827 for all patients, decreasing with increasing number of LOTs received (untreated?=?$27,211; LOT1?=?$9,601; LOT2?=?$7,325; LOT3+?=?$6,017).

Limitations: Potential for treatment misclassification when using the algorithm defining LOTs and non-generalizability of results to younger patients.

Conclusions: Over 50% of Medicare patients with mUC received no chemotherapy. Among chemotherapy-treated patients, most received only one LOT. Additional LOTs led to higher mean costs and HCRU, but as patients were followed longer, monthly costs decreased. As treatments evolve to include immuno-oncology agents, these findings provide a clinically relevant economic benchmark for mUC treatment across different traditional LOTs.     

An Empirical Quest to Identify the Most Dominant Negotiating Styles Among American Sales Managers

SUMMARY

This study addresses the proposition as to whether the collaborative negotiation style is the most prevalent among American sales managers in the competitive landscape created by the global economy. It also examines whether there are relationships between the sales managers' negotiation styles and selected personal and organizational characteristics that may affect negotiation styles. The findings of the study reveal that the collaborative style is indeed the most predominant. However, some sales managers do still emphasize the competitive style. This variation may imply Weitz's (1981) Weitz, B. 1981. Effectiveness in sales interactions: A contingency framework. Journal of Marketing, 45(1): 85–103. [Crossref], [Web of Science ®] , [Google Scholar] adaptive behaviors. There are also significant relationships between the sales managers' negotiation styles and personal and organizational characteristics.     

The Amenity and Disamenity Impacts of Agriculture: Estimates from a Hedonic Pricing Model

The positive and negative externalities from farmland are increasingly a focus of public policy discussion about agriculture and land use. A GIS-based hedonic pricing model shows that agricultural open space increases nearby residential property values, but larger-scale animal operations and mushroom production have negative impacts. Animal production facilities with as few as 200 animal equivalent units reduce nearby property values, but larger facilities do not necessarily generate larger impacts. Because they tend to occur together, the negative impacts of animal agriculture and the positive impacts of open space must be simultaneously modeled to avoid omitted variable bias.     

Applying the Institutional Theory at the Level of Halal Consumers: The Case of Cape Town in South Africa

The institutional theory, especially at an individual level, has not been conducted on halal consumers in South Africa. The purpose of this study was to evaluate the degree to which halal consumers who have higher institutional pressures are more expected to purchase halal food products. This study draws upon institutional theory to present empirical evidence that institutional factors may show a significant effect on halal consumer’s purchase intention and buying behavior toward purchasing halal food products. A sample of 298 halal consumers in South Africa was selected. Data samples were collected via self-administrated questionnaires. Structural equation modeling (SEM) was used to test study hypotheses. The study showed that all institutional factors have a direct effect on halal consumer’s intention and indirect effect on buying behavior. Based on the results, normative pressures had a high significant effect among institutional pressures, followed by other factors such as mimetic and coercive pressures, respectively. This study is first of the uncommon studies examining halal consumers’ purchase intention and buying behavior in a non-Muslim country, employing the institutional theory in the context of halal food consumption.     

Direct medical costs of treatment in newly-diagnosed high-grade glioma among commercially insured US patients

Aim: This analysis assessed the direct medical costs of newly-diagnosed, temozolomide (TMZ)-treated glioblastoma (GBM) from the perspective of a US commercial setting.

Materials and methods: The analysis included subjects identified from the IMS PharMetrics LifeLink Plus? claims database from January 1, 2008 to August 31, 2014 who were ≥18 years of age, had ≥1 malignant brain cancer diagnosis, had brain surgery ≤90 days prior to TMZ initiation, had TMZ treatment, and were continuously enrolled for ≥12 months pre-diagnosis and ≥1 month post-diagnosis. Per-patient per-month (PPPM) and cumulative costs from 3 months pre-diagnosis to various post-diagnosis follow-up time points were calculated. Multivariable analyses were used to estimate adjusted mean cost and identify contributors of cost.

Results: The study included 2,921 subjects (median age?=?56 years; 60% male). After diagnosis, the median (interquartile range, IQR) number of inpatient, emergency department, and outpatient visits were 2 (1–4), 1 (1–3), and 19 (13–27); median (IQR) length of stay per hospitalization was 5 (3–9) days. Mean total cumulative costs per patient from 3 months pre-diagnosis to 12 months and to 5 years post-diagnosis were $201,749 (197,490–206,024) and $268,031 (262,877–274,416). Mean (SD) PPPM costs were $818 (1,128) and $7,394 (8,676) pre- and post-GBM diagnosis, respectively. The variables most predictive of cumulative costs included radiation therapy (+$81,732), ≥2 weeks of hospitalization (+$49,629), and ≥7 MRI scans (+$40,105).

Conclusions: The direct medical costs of newly-diagnosed, TMZ-treated GBM in commercially insured patients are substantial, with estimated total cumulative costs of $268,031.     

Effects of household size and composition on consumption in rural households in Matabeleland South,Zimbabwe

This study, using a survey of rural households in Zimbabwe in 1990/91, focuses on the effects of changing household composition on patterns of expenditure and provides estimates of the ‘cost of a child’ as well as of family members in other age groups. In addition to age differences in the size and direction of responses to changing family composition, the paper highlights significant differences across product groups. These effects are more muted in larger households.
