Contested land tenure reform in South Africa: experiences from Namaqualand

In South Africa the distribution of land rights remains a major manifestation and cause of injustice, only slowly affected by the constitutionally mandated programme of land restitution, redistribution and tenure reform. The Transformation of Certain Rural Areas Act 94, 1998 (Trancraa) is the first post-apartheid legislation to reform ‘communal’ land tenure. It applies to 23 former ‘coloured rural areas’ and was introduced in six areas in Namaqualand in the Northern Cape Province during 2001–2. In a different, contested process a Communal Land Rights Bill for the former ‘homelands’ was published in August 2002, adopted by Cabinet in 2003 and signed into law in July 2004. While the Communal Land Rights Act relies on ‘traditional councils’ with a majority of non-elected members, Trancraa was enacted in the context of the 1997 White Paper of South African Land Policy and focused on community choice and the role of municipalities. The consultative process in Namaqualand was driven by civil society organisations and community actors, but did not include the training, finance and development support needed to transform rural relations among people affected by unemployment, land scarcity and weak local organisations. To promote procedural and substantive justice, tenure reform must honour the human rights of equality, redress and land development support articulated in land policy and the Constitution.     

The predictive validity of the Karnani and Wernerfelt model of multipoint competition

This study is the first to examine the predictive validity of the Karnani and Wernerfelt theoretical model. We developed measures for four variables, and explored whether they successfully operationalized the dimensions in the theoretical model. The model proposed four response strategies, and six were observed in the data. Incumbent firms most frequently did not respond at all to another firm's entry, even though a counterattack response was predicted by the model. Since the independent variables did not predict responses as proposed by the model, exploratory analyses identified “best” predictors of responses.     

Consumer heterogeneity in the longer-term effects of price promotions

While a significant literature has emerged recently on the longer-term effects of price promotions, as inferred from persistence models, there is very little if any attention paid to whether such longer-term effects vary across different types of consumers. This paper takes a first step in that direction by exploring whether the adjustment, permanent, and total effects of price promotions, and the duration of the adjustment period, differ between consumers segmented based on their usage rates in a product category and their loyalty to a brand. We also investigate whether such consumer segmentation will improve the forecasting performance of persistence models at both product category and brand levels. Expectations are developed based on consumer behavior theory on various effects of price promotions, such as the post-deal trough, the mere purchase effect, the promotion usage effect, and responsiveness to competitor's reactions. Evidence from household-level supermarket scanner data on four product categories is provided. We find substantial differences between consumer segments and provide insights on how managers can increase the longer-term effectiveness of price promotions by targeting each consumer segment with a different promotion program. In addition, consumer segmentation is found to significantly improve the forecasting performance of the persistence model for two of the four product categories. For the other two product categories, consumer segmentation provides forecasting performance similar to that obtained from aggregate-level persistence models.     

Best foot forward or best for last in a sequential auction?

Should a seller with private information sell the best or worst goods first? Considering the sequential auction of two stochastically equivalent goods, we find that the seller has an incentive to impress buyers by selling the better good first because the seller's sequencing strategy endogenously generates correlation in the values of the goods across periods. When this impression effect is strong enough, selling the better good first is the unique pure‐strategy equilibrium. By credibly revealing to all buyers the seller's ranking of the goods, an equilibrium strategy of sequencing the goods reduces buyer information rents and increases expected revenues in accordance with the linkage principle.     

Comparative evaluation of treatment patterns and healthcare utilization of newly-diagnosed rheumatoid arthritis patients by anti-cyclic citrullinated peptide antibody status

Background: Anti-cyclic citrullinated peptide (CCP) antibody positivity is an established diagnostic factor for severe disease activity and joint damage and a prognostic factor for aggressive disease in rheumatoid arthritis (RA).

Objective: To compare RA-related treatment, healthcare utilization, and joint erosion between anti-CCP-positive and anti-CCP-negative RA patients.

Methods: Newly-diagnosed RA patients were identified from the Henry Ford Health System database between January 1, 2009 and December 31, 2014; the date of the first RA diagnosis within the study period was the index date. Baseline anti-CCP test was used to categorize patients as anti-CCP-positive or anti-CCP-negative, and outcomes were evaluated in the 6 months post-index.

Results: There were 217 anti-CCP-positive and 191 anti-CCP-negative RA patients included in the study. A higher proportion of anti-CCP-positive patients were initiated on RA treatment than anti-CCP-negative patients (70.5% vs 23.0%; p?<?.0001). More anti-CCP-positive patients received methotrexate (73.2% vs 56.8%; p?=?.0374), while more anti-CCP-negative patients received hydroxychloroquine (31.8% vs 13.1%; p?=?.0037) in first-line therapy. A higher proportion of anti-CCP-negative patients were tested for rheumatoid factor (RF) and erythrocyte sedimentation rate (ESR). Of those tested, there were more positive test results in the anti-CCP-positive cohort compared to the anti-CCP-negative cohort (RF: 84.4% vs 18.2%, p?<?.0001; C-reactive protein [CRP]: 69.7% vs 48.3%, p?=?.0008; and ESR: 89.5% vs 53.9%, p?<?.0001). Outpatient utilization predominated, with more anti-CCP-positive patients having any outpatient physician office visit (96.3% vs 77.5%, p?<?.0001) and a higher mean number of visits (5.3 vs 2.5, p?<?.0001) than anti-CCP-negative patients. Among anti-CCP-positive (n?=?113) and anti-CCP-negative (n?=?58) patients with imaging results, more anti-CCP-positive patients had joint erosion compared to anti-CCP-negative patients (18.6% vs 8.6%; p?=?.0858); however, statistical significance was not reached.

Conclusion: RA patients with positive anti-CCP antibodies had higher degrees of inflammation and disease activity as indicated by laboratory results, which likely contributed to their higher rates of healthcare utilization, joint erosion, and proportions of RA treatment.     

The industrial implications of an optimal reflationary mix for the British economy

This paper derives an optimal reflationary mix for the next decade and comments on the industrial implications of this policy. The discussion is based on simulations of the multisectoral dynamic model of the UK economy developed by members of the Cambridge Growth Project. The results suggest that the concentration on macroeconomic policy alone may be misguided and that instruments which attack the roots of Britain's industrial problems should receive more attention. The paper also demonstrates that the optimal control procedure is a reliable tool for steering an economy towards a desired target trajectory and that this is feasible for very large econometric models.     

Visitor perceptions of the role of tour guides in natural areas

This paper explores the potential of tour guides to contribute to the protection of natural areas by educating their customers through interpretation and modeling environmentally appropriate behaviors. Applying Cohen's (1985) model of the guides' role, modified by Weiler and Davis (1993) Weiler, B. and Davis, D. 1993. An exploratory investigation into the roles of the nature-based tour leader. Tourism Management, 14(2): 91–98. [Crossref] , [Google Scholar], as a framework, it examines the potential role that kayak tour guides can play in shaping the experience of visitors to one marine area, the Pacific Rim National Park. It uses two approaches to explore the perceptions of clients about the role of kayak guides using: (1) a pre- and post-trip questionnaire and (2) participant observation. Results indicate that five of the six roles were rated high in importance, but one role, the communication role, was not as important. Comparing performance with importance attached to each role revealed congruence with five roles, but lower levels of performance in relation to importance with the role of “motivator of responsible behavior”. Variability within all of the importance and performance measures suggest that for some individuals, performance did not match importance, highlighting the need to consider market segmentation in future studies. These findings are discussed within the ecotourism paradigm, and their implications for protected area management and for visitor behavior modification are considered.     

Leisure and work ethics and locus of control

Abstract

Equivocal findings regarding the relationship between attitudes toward leisure and the extent to which people feel in control of their own fate led to the consideration of possible mediating influences. The current study was an attempt to examine the relationship between locus of control and the affective domain of leisure attitude, or leisure “ethic,” while controlling for the influence of work ethic. The possibility of differences between males and females and students and nonstudents led to four separate subgroup analyses. Results indicated that of the four groups, only female students showed a substantial relationship between locus of control and leisure ethic. In this group, leisure ethic was associated with an external locus of control, the tendency to regard the control of life's circumstances as lying outside oneself. In none of the groups was the influence of work ethic great enough to make an appreciable difference in the relationship between locus of control and leisure ethic. The group differences were discussed in terms of sex‐role orientations and career aspirations.
