Sustainable Livelihoods of Township Small, Medium and Micro Enterprises towards Growth and Development

In South Africa, small, medium, and micro enterprises (SMMEs) have been recognized as the critical driving force to alleviate some economic challenges that the country faces. The challenges, such as the alleviation of poverty and the unemployment rate, can be addressed by policies that encourage SMME developments and sustainability. The historical background of SMMEs in South Africa has left them operating in various locations, such as cities and townships. There is a growing concern of the lack of information and communications technology (ICT) adoption by SMMEs, in particular those operating in townships. The aim of this study was to develop an ICT adoption framework using the sustainability livelihood framework (SLF) to encourage ICT adoption and improve the livelihood of township SMMEs. This study used the sustainable livelihood framework (SLF) to explore the broader socio-economic contents of the township SMMEs on human, social, financial, and physical and natural resource-based assets that enable the poor to enhance their capabilities and reduce their vulnerabilities. This study deployed a qualitative exploratory research. A sample of 21 SMME owners/managers operating in Soweto was used, and data were collected using in-depth interviews and observations. The study revealed township SMMEs are complex and dynamic and need various interventions in order for them to be sustainable. The SLF for township SMMEs can be used as a guideline for SMME owners/managers and policy makers when formulating ICT adoption policy.
Life history and populational aspects of the Eastern harvest mouse

Reithrodontomys humulis in the Oak Ridge, Tennessee, area is found mainly in certain habitats dominated by grasses and other herbaceous plants characteristic of early vegetational succession. Populations seldom are dense, but on a 4 ha, old-field area, trapping success ranged from about 4 to 18 individuals per 100 trap nights for 18 consecutive months. This population on the old-field area disappeared during severely cold weather in February-March of 1960, but a few individuals survived on a radioactive area. More females than males were captured in the periods June-November 1958 and May-November 1959, whereas more males were caught from December 1959 to February 1960. However, the sex ratio was about equal over a period of a year or more. The reproductive season extended from about late spring to late fall, but breeding occurred during winters of some years. Litter sizes ranged from 1-8 (av. 3.4). Cannibalism and abandonment of litters were characteristic of newly caught females. Average weights for females during reproductive periods were consistently greater than average weights of males, but even during nonreproductive periods females weighed as much or more than males. Weights of trapped individuals ranged from 3-17 g. Mortality of nestlings appeared to be severe, but survival after leaving the nests seemed to be relatively long. Huddling was common during cold weather. Territoriality seems poorly developed. Some individuals occupied relatively restricted ranges for periods of several months, but other mice shifted their activities from one part of an area to another. Ranges of the mice were less during the colder months than during the warner months. Only heterosexual pairs of mice were ever trapped together, and these captures usually occurred during breeding periods. Erythrocyte count and mean corpuscular volume in the harvest mouse were not significantly different from the measurements for larger mice, but hemoglobin concentration and oxygen consumption were greater than in the larger mice.
Lesões foliares e de ramos de laranjeira-doce causadas pela leprose-dos-citros

The objective of this work was to present the anatomical description of tissues lesioned by Citrus leprosis virus cytoplasmatic type (CiLV-C), in leaves and twigs of 'Pera' sweet orange (Citrus sinensis (L.) Osbeck) providing new data to understand the interactions between the virus and the plant host, in Brazil. Leprosis lesions were cut on a rotary microtome (5-7 µm thick), stained and mounted in synthetic resin. For scanning electron microscope analysis, fixed tissues were immersed in glycerin 30% and criofractured, dehydrated in a graded ethylic series, critical point drying and coated with gold. Foliar lesions began as necrotic points surrounded by a yellow halo that inhibited the lesion expansion. The twigs presented two different lesions: depressed ones and pustules with ruptures. There was hyperplasia of the cortical and phloematic parenchyma cells causing the obliteration of phloematic vessels. These histological alterations of the phloem tissue could explain why the virus does not become systemic even occasionally infecting phloem parenchyma cells. The development of gummosis traumatic ducts in twig lesions was described here.
Two sides of the same coin: can campaigns generate support for both human rights and retributive violence?

ABSTRACT Do framing strategies that are effective at encouraging pro-social behavior, such as participation in human rights campaigns, also mobilize support for violence within the same subjects? We use an experimental research design to examine individuals’ reactions to personal, humanizing narratives about past victimization. Participants are randomly assigned to one of eight treatment groups, which variously highlighted the humanity of the subject, the intensity of the past violence, and/or an evocative photograph of the subject that underscores her loss and vulnerability. We expect narratives that emphasize the subject’s humanity will encourage the audience to see the subject as innocent and as a victim, but also to feel angry about her experience. As a result, individuals will be more likely to defend the subject’s human rights, and to condone her use of retributive violence. We find that humanizing narratives lead respondents to simultaneously support a human rights appeal on the subject’s behalf and her use of retributive violence. Perceiving the subject in the narrative as innocent or as a victim mediates these effects, but anger often does not.
Floristic Composition, Diversity, and Biomass of a Protected Tropical Evergreen Forest Belize

A challenge in community ecology is the development of ecosystem baselines, allowing the assessment of the variation in the ecological dynamics through different temporal and spatial scales. To our best knowledge, no studies have been carried out in seasonal evergreen forests of Belize to establish a baseline for future monitoring. Hence, a floristic study of the woody plant species diversity and composition was carried out at the Billy Barquedier National Park (BBNP) to develop an ecosystemic baseline for the assessment of the originally implemented conservation strategies. A thorough floristic survey was performed from May to August 2015 in 42 rectangular plots (500 m2) randomly allocated along the 100 to 500 m elevation gradient of the BBNP. Species richness, diversity, composition, and aboveground biomass were assessed. Likewise, information of a series of indicators on protection and risk situation (e.g., IUCN Red List of threatened species, CITES categories), and restoration for each relevant species are also provided. The BBNP is an important forest with 67 woody species distributed in 30 plant families. Terminalia amazona and Corozo palm Attalea cohune are the most important species in the reserve, in terms of abundance, frequency, and biomass. A clear trend between biodiversity metrics, elevation, and aboveground biomass was noted. This study contributes to understand relevant ecological topics as well as provides key elements for the management and conservation of the BBNP area and Belize.
Comparison of time-activity budgets and population structure for 18 large-bird species in the Kruger National Park, South Africa

The activity, age, sex and group size was recorded for 10 177 instantoneous samples of 18 species of large (> 1 kg) birds in the Kruger National Park, South Africa, during 1991–94. The samples (75–2816 per species) were compared for four foraging guilds, of terrestrial (4 spp.), predatory (5 spp.), scavenger (5 spp.) and aquatic (4 spp.) species. Most results for individual species were similar to focal-animal studies and to other information in the literature. Members of the terrestrial guild were most often on the ground (58–78%). Predators and scavengers were most often in flight or perched (90–100% and 67–96%, respectively) but scavengers were more often standing on the ground (2–23%). Aquatic species were most often feeding or standing (49–65%). Predatory species were most often alone or in pairs, as were predatory members of other guilds (Sagittarius, Terathopius, Trigonoceps). Two terrestriol species were in small social groups (Struthio, Bucorvus), while scavengers and aquotic species were most often in larger groups. The proportion of immatures recorded within species was 3–35%. For seven dimorphic species, the sex ratio deviated from equality for the two social terrestrial species (Struthio, Bucorvus). Differences between species within guilds were often related to detailed differences in their ecology
‘Dead skin’ on yams (Dioscorea alata) caused by Colletotrichum gloeosporioides

A storage rot of yams (Dioscorea alata), commonly referred to as ‘dead skin′, has recently become a major constraint to yam production in the Caribbean. The fungal pathogen Colletotrichum gloeosporioides was consistently isolated from affected tubers and re-inoculation of healthy yam tubers resulted in the development of typical symptoms of dead skin.
A Taxonomic Assessment of Racomitrium steerei (Grimmiaceae, Musci) from Venezuela

Abstract: Bednarek-Ochyra, H. 2014. A taxonomic assessment of Racomitrium steerei (Grimmiaceae, Musci) from Venezuela. –Herzogia 27: 141–146. Racomitrium steerei from the northern Andes of Venezuela is taxonomically assessed and some diagnostic traits of the type material are illustrated. An investigation of the type material revealed that this species is inseparable from Bucklandiella lamprocarpa, a south-pan-temperate species which extends into the Neotropics along the Andean chain. Diversity of the Grimmiaceae subfam. Racomitrioideae in northern South America is briefly outlined.
Agglomeration Effect of Skill-Based Local Labor Pooling: Evidence of South Korea

Since workplace skills present diverse dimensions of a worker’s ability, it has recently received renewed interest by researchers examining the growth of cities. The purpose of the paper explores the advantage of regional concentrations of workers specialized in different types of skills. Specifically, the analysis estimates the agglomeration effects of skill-based labor pooling on wage levels and wage growth in South Korea. To this end, it constructs skill-based labor pool indices for cognitive, social, technical, and physical skills at a provincial level. The indices show an uneven geographical distribution in varying degrees across four types of skills. The regression results indicate that the urban wage premium of skill-based local labor pooling varies according to types of skills. The greatest magnitude of benefit is incurred by workers in cognitive-skill-oriented occupations and moderate benefits are found in technical- and physical-skill-oriented occupations. An urban wage premium is non-existent in social-skill-oriented occupations. In addition, the wage growth model with job mobility shows that the urban wage premium immediately affects workers who change jobs and relocate to denser areas. As high-wage occupations earn higher wage premiums when workers in these occupations are concentrated, it supports patterns of the polarization of both skills and their effects.
Enhancing a -Amylase and Cellulase in vivo enzyme expressions on Sago Pith Residue Using Bacillus amyloliquefaciens UMAS 1002

The effect of Solid State Fermentation (SSF) parameters on the production of extracellular α-amylase and cellulase (endoglucanases) by Bacillus amyloliquefaciens UMAS 1002 using sago pith residue hampas in shaker flasks was investigated in this study. The appropriate incubation period, temperature, pH, agitation speed, inoculum concentration, hampas concentration and additive substrate effect were optimized for enzyme production. The activity of α-amylase and cellulase was at 14.19 and 13.15 IU mL-1, respectively in optimal culture medium. Maximum yield for both enzymes were achieved by employing 4% w/v hampas in 0.2 M citrate buffer at pH 6 and incubated at 40°C for 6 h with agitation speed of 100 rpm. Inoculum concentrations were found to be optimum at 3% v/v and 4% v/v for α-amylase and cellulase, respectively. Enzyme activity was 2.8 (10.80 IU mL-1) and 3.2 (9.38 IU mL-1) fold higher for α-amylase and cellulase respectively when 1% w/v soluble starch was applied as additive substrates with 0.5% hampas. However in optimal media that consist of 4%w/v of hampas, addition of 1% w/v soluble starch intend to inhibit both enzyme productions. Result revealed that temperature, pH and shaking condition were the most significant factors for the production of α-amylase and cellulase enzyme. Temperature influenced enzyme production by affecting the other parameters including bacterial growth, pH, Dissolved Oxygen (DO) and reducing sugars. Nevertheless, shaking condition could affect DO concentration that in turn affected bacterial growth and enzymes production too.
Site selection and fidelity by crested porcupines for denning

The crested porcupine is a large rodent living in Central and North Africa, with a European distribution limited to Italy. Its biology and particularly its denning habits are inadequately known. Our study was carried out in a Mediterranean coastal area of central Italy. We radiotagged 13 adult porcupines, assessing their den site selection and use each month, from February 1998 to September 1999. Porcupines preferred steep, compact soils covered with dense vegetation, for denning. Each den was always used by the same 2 individuals, possibly forming a reproductive pair. Paired individuals seemed to show a greater site fidelitythan single ones. Intepretations of this behaviour are discussed.
Unusual Location of the Geotail Magnetopause Near Lunar Orbit: A Case Study

The Earth's magnetopause is highly variable in location and shape and is modulated by solar wind conditions. On 8 March 2012, the ARTEMIS probes were located near the tail current sheet when an interplanetary shock arrived under northward interplanetary magnetic field conditions and recorded an abrupt tail compression at ∼(‐60, 0, ‐5) RE in Geocentric Solar Ecliptic coordinate in the deep magnetotail. Approximately 10 minutes later, the probes crossed the magnetopause many times within an hour after the oblique interplanetary shock passed by. The solar wind velocity vector downstream from the shock was not directed along the Sun‐Earth line but had a significant Y component. We propose that the compressed tail was pushed aside by the appreciable solar wind flow in the Y direction. Using a virtual spacecraft in a global magnetohydrodynamic (MHD) simulation, we reproduce the sequence of magnetopause crossings in the X‐Y plane observed by ARTEMIS under oblique shock conditions, demonstrating that the compressed magnetopause is sharply deflected at lunar distances in response to the shock and solar wind VY effects. The results from two different global MHD simulations show that the shocked magnetotail at lunar distances is mainly controlled by the solar wind direction with a timescale of about a quarter hour, which appears to be consistent with the windsock effect. The results also provide some references for investigating interactions between the solar wind/magnetosheath and lunar nearside surface during full moon time intervals, which should not happen in general.
Extreme chromosomal polytypy in a population of sceloporus grammicus (sauria: phrynosomatidae) at santuario mapethé, Hidalgo, México

-The karyotypic status of the mesquite lizard, Sceloporus grammicus, was investigated at two localities at Santuario Mapethe, Hidalgo, Mexico. A total of 23 different karyotypes was recorded from the 36 individuals examined. Individual lizards were heterozygous at up to four chromosomes. Karyotypic differences were attributed to Robertsonian fission/fusions and pericentric inversions involving the macrochromosomes. The polymorphisms generally conformed to Hardy-Weinberg equilibrium suggesting a lack of underdominance for most rearrangements. The extreme chromosomal polytypy observed at Santuario Mapethe is hypothesized to result from parapatric hybridization between two chro-
Extrapair paternities in black‐browed Thalassarche melanophris, grey‐headed T. chrysostoma and wandering albatrosses Diomedea exulans at South Georgia

Extrapair paternities (EPP) are relatively common in passerines, but rare in seabirds. Like most seabirds, albatrosses are long lived, form long-term pair bonds and require biparental care for chick-rearing. Microsatellite analyses of 327 chicks from black-browed Thalassarche melanophris, grey-headed T. chrysostoma and wandering albatrosses Diomedea exulans over two breeding seasons revealed the presence of EPP in all three species. Though EPP rates varied between species and years, up to 21% of offspring were the result of extrapair matings. Rates were highest in wandering albatrosses (6–21%) followed by grey-headed (3–10%) and black-browed (0–9%) albatrosses. EPP rates were lower in 1998 compared to 1999 in both black-browed and grey-headed albatrosses, whereas the reverse was true for wandering albatrosses. Interspecific differences in EPP rates may reflect differences in breeding phenology and sexual size dimorphism. Differences in timing and frequency of breeding may promote different opportunities for interactions with birds other than their normal partner. The different breeding habitat, dispersion and mate-attraction rituals in wandering albatross, together with the disparity in size between the sexes may also offer more scope for higher rates of EPP. Despite extensive sampling within each colony, we were unable to identify sires for many of the extrapair young; however males from other colonies were involved, raising interesting questions regarding the timing and nature of such events.
A mathematical framework for effective routing over low power and lossy networks

With the rapid advancement in the Internet of things, protocols are challenged to perform routing with low power over lossy networks (RPLs). Performance analysis of RPL attracted many researchers in the field. However, to the best of our knowledge, limited or no studies have been made to develop heterogeneous analytical models that aim at the classification and ranking of RPL deployments based on combinations of desired properties. In this paper, we develop an analytical framework that captures the effectiveness of RPL and enables its sound evaluation and classification. Performance metrics include power consumption, churn in, received packets, and duty cycle, to name but a few. The obtained results based on our analytical framework confirms its effectiveness compared to the simulation results obtained in the literature. The best performance is noted for the deployments with 50 m of range and for different number of nodes.
Characteristics of chimpanzee (Pan troglodytes) ejaculates collected by rectal probe electrostimulation and by artificial vagina

This study compares characteristics of ejaculates collected from 16 adult male chimpanzees using rectal probe electrostimulation (RPE) and from 10 adult male chimpanzees trained to use an artificial vagina (AV). Ejaculate weight, semen volume, and sperm number were significantly lower (P < 0.01) and percentage liquefaction was significantly higher (P < 0.01) in ejaculates collected by RPE. Percentages of motile sperm and of live sperm in semen did not differ significantly between the two collection methods. Total amounts of protein and of α‐glucosidase activity were significantly lower (P < 0.01) in seminal fluid from RPE samples. For ejaculates collected by RPE, semen volume correlated positively with protein (r = 0.8640, P < 0.001), fructose (r = 0.6976, P < 0.001), and citrate (r = 0.6976, P < 0.001); sperm number correlated positively with α‐glucosidase activity (r = 0.6547, P < 0.001); and protein correlated positively with fructose (r = 0.5906, P < 0.002), citrate (r = 0.5926, P < 0.002) and α‐glucosidase activity (r = 0.6006, P < 0.001). For ejaculates collected by AV, semen volume correlated positively with percentage liquefaction (r = 0.6058, P < 0.001), protein (r = 0.8055, P < 0.001), fructose (r = 0.6606, P < 0.001), and citrate (r = 0.8272, P < 0.001); sperm number correlated positively with percentage of motile sperm (r = 0.4196, P 0.004); percentage of motile sperm correlated positively with percentage of live sperm (r = 0.4388, P < 0.002); and, protein correlated positively with fructose (r = 0.6947, P < 0.002) and with citrate (r = 0.5926, P < 0.002). These data show that there is a significant difference in semen parameters and in biochemical parameters of ejaculates obtained by RPE and by AV. © 1995 Wiley‐Liss, Inc.
Development of a specific assay using RISA for detection of the bacterial agent of 'basses richesses' syndrome of sugar beet and confirmation of a Pentastiridius sp. (Fulgoromopha, Cixiidae) as the economic vector

A technique for the specific diagnosis in insects of SBRp (the γ-3 proteobacterium associated with the syndrome ‘basses richesses’ (SBR) of sugar beet crops in eastern France), using the RISA (rDNA intergenic spacer analysis) technique, was developed. PCR using the Alb1/Oliv1 primer pair specifically amplified a 16S-ITS region of SBRp and produced a characteristic DNA fingerprint. This PCR assay did not detect other closely related organisms, including the Arsenophonus endosymbiont of Diaphorina citri, the secondary endosymbiont of Glycaspis brimblecombei, or ‘Candidatus Phlomobacter fragariae’, a related phytopathogenic γ-3 proteobacterium. Six different ribosomal operons, differing in their ITS region or partial 16S sequence, were identified in SBRp. PCR amplification with Alb1/Oliv1 of DNA samples from Hemiptera species (suborders Fulgoromorpha and Cicadomorpha) collected in sugar beet fields confirmed Pentastiridius sp. as the economic vector of SBR disease. The high percentage of field-Pentastiridius sp. specimens which tested positive for SBRp reflected the importance of SBR disease in sugar beet crops. This is the first time that the RISA technique has been used as a diagnostic test for a plant pathogenic bacterium in insects.
Re-description of Strandesia sanoamuangae Savatenalinton & Martens, 2010 and description of a new species of Strandesia (Crustacea, Ostracoda) from Grande Terre, New Caledonia

The New Caledonian Archipelago is a hot spot for biodiversity and endemism. Whereas popular groups such as birds and plants are well-studied, invertebrate groups such as ostracods remain ill-known. Here, we re-describe Strandesia sanoamuangae Savatenalinton & Martens, 2010, originally described from Thailand (8000 km away from New Caledonia), and describe Strandesia mehesi sp. nov. Both species are known only from females. Material for the present study was collected from diverse aquatic non-marine habitats from Grande Terre, the main island of New Caledonia. Whereas S. sanoamuangae is seemingly easily identifiable, S. mehesi sp. nov. is part of the Strandesia vinceguerrae/vavrai species cluster in the genus, of which the ‘older’ species (described long ago) often have incomplete and superficial descriptions. Differentiation between the new species and the other members of this species cluster are based on small anatomical details of the valves. The current paper updates the known number of recent freshwater Ostracoda of New Caledonia from 14 to 16 species, although at least five of these species have an uncertain status.
