Geographical Indication Protection in South Africa with particular reference to wines and the EU connection
From text: Indications of the geographical origin of goods are becoming increasingly important in the trade environment. This is especially the case where the association between goods and country of origin carries a connotation of some or other uniqueness such as quality or other characteristics. Protection under such indication of geographical origin is found in the benefit that producers of associated goods can prevent producers of similar goods from outside the region from identifying their goods with the region via such indication
The Durban University Of Technology's Experiences Of Open Educational Resources
There seems to be growing confidence that the open education movement is set to reshape the higher education landscape. Perhaps the single most formidable challenge retarding the uptake of open education resources (OERs) is instructors' lack of knowledge and experience of these materials. This descriptive case study examines the experiences Durban University of Technology (DUT) faculty have of OERs. As such, it lays the groundwork for subsequent studies of the attitudes of faculty to OERs and to the philosophy of open education. It also interrogates the national and institutional policy environment to establish to what extent these foster a culture of sharing and openness in local higher education. The findings reported here may thus provide a context for understanding the attitudes of DUT faculty to OERs (examined in a separate study) and may serve as useful indicators of how the university is positioned; that is, how deep its foundations are, with respect to its prospects of participating successfully in the higher education OER movement
Are Higher Education Institutions Positioned To Reap The Dividends Of Open Education Resources? The Case Of Durban University Of Technology
The potential benefits of open education resources (OERs) are well documented in the literature. These include cheaper education, improved equity in respect of educational prospects, greater access to higher education opportunities for non-traditional learners, encouraging new modes of collaborative learning and leveraging public funds by sharing knowledge. So compelling are these advantages that leading universities globally are currently experimenting with new business models calibrated to extract value from educational offerings that, increasingly, will be expected to include free content. In spite of the obvious merits of OERs, the open education movement faces challenges which are rooted significantly in educators' perceptions of these resources. This descriptive case study sought to examine the attitudes Durban University of Technology (DUT) faculty have towards OERs with the aim of gauging their capacity to be actively involved as developers and users of these materials. The study found that in spite of respondents' recognition of the advantages of OERs and even a degree of superficial employment of these instructional aids, there appears to be no real open education ethos at the institution. Evidence of this includes the relatively low level of sharing of content amongst faculty and the consensus of respondents that there is no institutional support for OER initiatives. The study concludes that for the university to retain its relevance in an evolving educational landscape, it should create a framework that will not only create space for OER projects but should also address the very human need for recognition and acknowledgement that developers of free and open content have

Phase I and Phase II control charts for the variance and generalized variance
By extending the results of Human, Chakraborti and Smit (2010), Phase I control charts are derived for the generalized variance when the mean vector and covariance matrix of multivariate normally distributed data are unknown and estimated from m independent samples, each of size n. In Phase II predictive distributions based on a Bayesian approach are used to construct Shewart-type control limits for the variance and generalized variance. The posterior distribution is obtained by combining the likelihood (the observed data in Phase I) and the uncertainty of the unknown parameters via the prior distribution. By using the posterior distribution the unconditional predictive density functions are derived

Dicaesium diaquaÂbisÂ(methylÂeneÂdiphosphoÂnato-κ2 O,O′)cobaltate(II)
The asymmetric unit of the title compound, Cs2[Co(CH4O6P2)2(H2O)2], is comprised of one bidentate methylÂenediphosphoÂnate ligand and one water molÂecule which are coordinated to the CoII atom, as well as a caesium counter-cation. The Co atom occupies a special position on a crystallographic inversion center. The caesium ion is octaÂhedrally coordinated by six O atoms with Cs—O distances ranging from 3.119 (2) to 3.296 (2) Å. A three-dimensional network is formed through O—H⋯O hydrogen bonds

Disodium diaquaÂbisÂ(methylÂenediÂphosÂphoÂnato-κ2 O,O′)cobaltate(II) dihydrate
In the title compound, Na2[Co(CH4O6P2)2(H2O)2]·2H2O, the asymmetric unit is composed of one methylÂenediphosphoÂnate ligand and one water molÂecule, which both are coordinated to a CoII atom, as well as a non-coordinated water molÂecule and a sodium cation. The CoII atom occupies a special position on a crystallographic inversion centre. The slightly distorted CoIIO6 octaÂhedral coordination environment is composed of two bidentate methylÂenediphosphoÂnate ligands and two coordinated water molÂecules in trans positions. The sodium ion is octaÂhedrally coordinated to six O atoms with Na—O distances ranging from 2.3149 (12) to 2.6243 (12) Å. An extensive three-dimensional network of interÂmolecular as well as intraÂmolecular O—H⋯O and C—H⋯O hydrogen bonding interÂacions is present
Pyridinium diaquaÂbisÂ(methylÂenediphosphoÂnato-κ2 O,O′)chromate(III) tetraÂhydrate
In the title complex, (C5H6N)[Cr(CH4O6P2)2(H2O)2]·4H2O, the CrIII atom, lying on an inversion centre, is coordinated by two bidentate methylÂene diphosphoÂnate ligands and two water molecules in a distorted octaÂhedral coordination geometry. The pyridinium cation is located on an inversion centre, with an N atom and a C atom sharing a position each at a half occupancy. A three-dimensional network is constructed by O—H⋯O, N—H⋯O and C—H⋯O hydrogen bonds between the pyridinÂium cation, complex anion and uncoordinated water molÂecules
