CIOs in Hungary, Romania, and South Africa (SA) are today overcoming disadvantages that their firms suffered during decades of closed national markets. This paper reports on a series of interviews conducted with CIOs in these developing countries focusing on national and organizational strategies used to prepare for international competition and globalization. They achieved competitiveness by i...
Yellow tulp (Moraea pallida Bak.), collected predominantly during the flowering stage from a number of sites in South Africa, showed large variation in digoxin equivalent values, indicating variability in yellow tulp toxicity. Very low values were recorded for tulp collected from certain sites in the Northern Cape.
BACKGROUND There are no available data concerning the incidence and the clinical pattern of coeliac disease in immigrant children coming to Italy from developing countries. AIMS To evaluate the epidemiological and clinical features of coeliac immigrant children coming to Italy. PATIENTS AND METHODS Hospital records of 1917 children diagnosed in 22 Italian Centres from 1999 to 2001 as having...
Screening of undocumented migrants or refugees for hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV) infections has been offered free of charge and free from bureaucratic procedures since 2012 at four primary-level clinical centres in Naples and Caserta, Italy. Of 926 undocumented migrants and refugees visiting one of the primary-level clinical centres from...
BACKGROUND Due to its complex, dynamic and well-known paleogeography, the Mediterranean region provides an ideal framework to study the colonization history of plant lineages. The genus Linaria has its diversity centre in the Mediterranean region, both in Europe and Africa. The last land connection between both continental plates occurred during the Messinian Salinity Crisis, in the late Miocen...
[1] Current good practice guidelines for national greenhouse gas inventories requires that seasonal variation in emission factors from savanna fires be considered when compiling national accounts. African studies concluded that the emission factor for methane decreases during the dry season principally due to curing of the fuels. However, available data from Australian tropical savannas shows n...
The objective of this study was to determine the species composition of ixodid ticks infesting domestic dogs in the northwestern region of the Northern Cape Province of South Africa and in Namibia. Ticks were collected from February 2008 to January 2009 from dogs presented for a variety of reasons at a veterinary clinic in the Northern Cape Province and at 3 clinics in Namibia. The ticks collec...
The spatial and temporal global distribution of deep clouds was analyzed using a four-year dataset (2007–10) based on observations from CloudSat and CALIPSO. Results showed that in the Northern Hemisphere, the number of deep cloud systems (DCS) reached a maximum in summer and a minimum in winter. Seasonal variations in the number of DCS varied zonally in the Southern Hemisphere. DCS occurred mo...
Here we report the draft genome sequence of Hymenobacter sp. CRA2 isolated from the Nama Karoo shrub land soils of the Northern Cape, South Africa. This genome is approximately 5.88 Mb long and the assembly comprised 45 contigs. The draft genome sequence has been deposited in DDBJ/EMBL/GenBank under the accession number NZ_MVBC00000000 and is available for download at: https://www.ncbi.nlm.nih....
There is great uncertainty over the timing and magnitude of the termination of the African Humid Period (AHP). Spanning from the early to middle Holocene, the AHP was a period of enhanced moisture over most of northern and eastern Africa. However, beginning 8000 years ago the moisture balance shifted due to changing orbital precession and vegetation feedbacks. Some proxy records indicate a rapi...
