The impacts of tourism on two communities adjacent to the Kruger National Park, South Africa
No full textThis paper explores the socioeconomic impacts of tourism associated with the Kruger National Park, South Africa's flagship national park, on the neighbouring villages of Cork and Belfast. Case study research, where the study area was characterised as a social-ecological system, was used to investigate the impacts of Park tourism on these communities. The findings offer a micro-scale, local community perspective of these impacts and indicate that the enclave nature of Park tourism keeps local communities separate from the Park and makes it hard for them to benefit from it. The paper concludes with reflections on this perceived separation, and suggests the need to make the Park boundaries more 'permeable' so as to improve relationships with adjacent communities, while also pragmatically managing community expectation

Are giraffes pollinators or flower predators of Acacia nigrescens in Kruger National Park, South Africa?
No full textWe examined the relationship between giraffes (Giraffa camelopardalis) and Acacia nigrescens in Kruger National Park, South Africa, to determine whether these tall ungulates may be providing a pollination service for the trees, or are simply flower predators. We quantified florivory and subsequent fruit set in the presence and absence of giraffes. Acacia nigrescens flowers are clearly a substantial dietary component for giraffes. Although A. nigrescens flowers contain almost three times as much condensed tannin as leaves, giraffes consume large quantities of flowers (∼85% of flowers within reach), resulting in distinct browse lines on the trees. This substantial florivory is detrimental to the overall fecundity of A. nigrescens, with significantly reduced fruit set at heights on trees that are accessible to giraffes. Fruit set increased above the reach of giraffes, suggesting successful pollination by insects. Giraffes were effectively flower predators of A. nigrescens in the season we examined
From SO2 to Greenhouse Gases: Trends and Events Shaping Future Emissions Trading Programs in the United States
No full textCap-and-trade programs have become widely accepted for the control of conventional air pollution in the United States. However, there is still no political consensus to use these programs to address greenhouse gases. Meanwhile, in the wake of the success of the U.S. SO2 and NOx trading programs, private companies, state governments, and the European Union are developing new trading programs or other initiatives that may set precedents for a future national U.S. greenhouse gas trading scheme. This paper summarizes the literature on the “lessons learned” from the SO2 trading program for greenhouse gas trading, including lessons about the potential differences in design that may be necessary because of the different sources, science, mitigation options, and economics inherent in greenhouse gases. The paper discusses how the programs and initiatives mentioned above have been shaped by lessons from past trading programs and whether they are making changes to the SO2 model to address greenhouse gases. Finally, the paper concludes with an assessment of the implications of these initiatives for a future U.S. national greenhouse gas trading program.climate change, emissions trading, European Union, U.S. states, corporate environmentalism
Evidence for relatively greater subcutaneous fat deposition in stunted girls in the North West Province, South Africa, as compared with non-stunted girls
No full textObjective: we examined differences in body composition between stunted and non-stunted girls, with adjustments for confounding factors.Methods: a cross-sectional study was conducted in a representative sample of 478 African school girls, ages 10 to 15 y, in the North West Province, South Africa. Height, weight, skinfold thicknesses, and waist and mid upper arm circumferences were measured by trained biokineticists using standard methods. Trained fieldworkers measured dietary intakes by 24-h recall, and physical activity was measured by using the physical activity recall of the previous day. Body mass index and physical activity category were calculated.Results: stunted girls had significantly lower weight and skinfold thicknesses than did non-stunted ones. After including the covariates: age, years since menarche, school, type of housing, dietary energy and fat intakes, physical activity category, body weight, and stratum of urbanization in analysis of variance, the mean sum of triceps skinfold and subscapular skinfold thicknesses of stunted girls was greater than that of the non-stunted girls (P < 0.002). Stunted subjects were less active than non-stunted ones.Conclusion: this manifestation of relatively more subcutaneous fat and greater waist circumference in stunted girls may be involved in the development of obesity among black women in South Africa
The role of acid in the formation of hydrogen-bonded networks featuring 4,4'-dicarboxy-2,2'-bipyridine (H2dcbp): Synthesis, structural and magnetic characterisation of {[Cu(H2dcbp)Cl2].H2O}2 and [Cu(H2dcbp)(NO3)2(H2O)]
No full textReported herein are the synthesis, structural and magnetic characterisation of two hydrogen-bonded networks featuring the 4,4?-dicarboxy-2,2?-bipyridine (H2dcbp) ligand: {[Cu(H2dcbp)(Cl)2]·H2O}2 1 and [Cu(H2dcbp)(NO3)2(H2O)] 2. Compounds 1 and 2 result from the reaction of CuCl2 and Cu(NO3)2, respectively, with H2dcbp under hydrothermal conditions in the presence of either HCl or HNO3. The acid ensures that H2dcbp remains protonated and provides the anions required for charge balance irrespective of Cu(II) precursor. Within 1 and 2 the H2dcbp ligand performs a dual role of Cu(II) coordination, via the 2,2?-bipyridine moiety, and propagates the formation of chains through hydrogen-bonding involving the peripheral 4,4?-dicarboxylic acid functionalities. Additional hydrogen bonding between the 4,4?-dicarboxylic acid groups, metal bound chloride and nitrate anions, in 1 and 2 respectively, and water molecules generate 3D networks. Variable temperature magnetic susceptibility measurements reveal very weak antiferromagnetic coupling between the Cu(II) centres across the chloride bridges in 1 (J = ?3.02 cm?1)
Aerodynamic and performance characteristics of a passive leading edge Kruger flap at low Reynolds numbers
No full textAn experimental and numerical study was performed on a Clark Y aerofoil with a
10% chord leading edge Kruger flap to examine its aerodynamic performance at
Reynolds numbers of 0.6 × 106, 1 × 106, and 1.6 × 106, to help to identify the
forces and moments acting on a basic configuration. A detailed comparison of the
numerical and experimental data is presented in this paper. The leading edge
flap was effective at high angles of attack with an increase in CL of up to 18%
over a conventional no flap configuration and delayed separation by up to 3°.
The moments around the Kruger flap rotation point were calculated from the
numerical analysis as an initial stage in the design of a UAV passive flap
system and they are also presented in the p
