Características de la agrobiotecnología
Authors: Martínez C. Róger 
Published: April 2017

Las semillas transgénicas, una innovación biotecnológica, representan tanto promesas como peligros para los agricultores, los consumidores y el ambiente...y vislumbran ganancias multimillonarias para las empresas transnacionales. Pero como técnica nueva, todavía no se sabe las consecuencias sobre el largo plazo ni aun el plazo inmediato, pues existen muchos peligros para la salud humana y el ambiente. Las políticas neoliberales y transnacionales destruyen la soberanía alimentaria, por eso deben sentir el impacto de los movimientos ambientalistas, laborales y campesinos, de modo que reorienten su trabajo para el beneficio de toda la sociedad y de la naturaleza.

Published: April 2017

An experiment was set up in the Research Farm of Patuakhali Science and Technology University, during the rabi season of 2015 to evaluate the effect of fertilizers and manures on the growth and yield of Potato. The experiment was laid out in a Randomized Complete Block Design (RCBD) with two potato varieties namely Diamant (V1) and Cardinal (V2) and five different types and rates of organic manures and inorganic fertilizers viz. T0: Control , T1: NPK, T2: NPK + CW(Cowdung), T3: NPK+ PM(Poultry Mannure) and T4: CW(Cowdung), + PM(Poultry Mannure) were used for the present study. The twofactor experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Result showed that almost all the characters were affected significantly due to the effect of varieties, organicinorganic fertilizer and their combinations .In case of treatments, NPK with PM also showed the tallest plant (39.76 cm), highest fresh and dry weight (95.97 and 6.05 g plant1, respectively), CGR and RGR (0.086 and 0.218 g m2 day1, respectively), gross (24.36 t ha1) and marketable (23.39 t ha1) compared other treatments. In case of interaction, the highest plant height (41.00 cm), highst fresh and dry weight (96.87 and 3.62 g plant1, respectively), highest CGR and RGR (0.089 and 0.228 g m2 day1, respectively) as well as the highest gross (24.45 t ha1) and marketable (23.67 t ha1) yield were recorded in Diamant at NPK with PM. From the above observation it may be concluded that the variety Diamant at NPK + PM was more effective under Patuakhali region.Progressive Agriculture 27 (4): 435-443, 2016

Published: April 2017

The purpose of this study was to analyze the socio-economic structure of water buffalo farming at some selected coastal areas of Bhola district of Bangladesh. Data were collected from the 35 small and large farms by surveying during the period January to March, 2015. The study revealed that buffalo rearing was mostly practiced by middle (30-45yrs) and old (>45yrs) aged farmers than young farmers (<30yrs). Majority (45.71%) of the buffalo farmers were educated, have no organized housing facilities for sheltering and depend on locally available roughages and tree leaves to fed buffaloes. The average lactation length was found 228 days andmilk yield was 2.1 litres/ buffalo/ days. The Gross Margin and Net farm profitability per dairy buffalo per lactation year over cash cost and non-cash cost were stood at Tk. 55866.65 & Tk. 51127.89 and Tk.44954.65 & Tk. 40435.39 for Herd size-1 and Herd size-2, respectively that indicates rearing of small- scale dairy buffaloes is highly profitable at coastal belt areas in Bhola District. The average Benefit Cost Ratio (BCR) was accounted for 1:7.51 and 1:3.11, respectively over cash and total cost basis considering both herds. Finding of this study indicates that buffalo rearing is highly profitable in the coastal areas of Bangladesh and a crucial pathway for poverty alleviation.Progressive Agriculture 27 (4): 502-510, 2016
Use of moisture meter on the post-harvest loss reduction of rice
Authors: Hossain MA , Awal MA , Ali MR , Alam MM 
Published: April 2017

Moisture content is one of the most important factors determining grain quality during harvesting, storage, trading, processing, and transportation because high moisture will create problems for farmers, especially during postharvest activities such as mold growth, higher insect infestation, loss in seed germination, and low market price. A study was conducted to find out a precise moisture meter (MM) for moisture content (MC) determination during post-harvest activities of rice. John Deere moisture meter (JD MM), Moisture Probe and RiceterL MM were tested and calibrated to provide accurate result compared to that of Oven dry method. The average MC of same samples was found 11.4, 11.8, 12.3, and 13.1% by Oven dry method, Moisture Probe, RiceterL and John Deere MM, respectively. Standard deviations of the mean are 0.11, 0.17, 0.13 and 0.22, respectively by the corresponding moisture meters. Oven dry method i.e. drying whole kernels for 72 h at 105°C had the smallest standard deviation. This indicated long drying time and adequate drying temperature could ensure the precision of moisture determination. The reading of John Deere, Moisture Probe and RiceterL MM is higher by 1.7, 0.4 and 0.9%, respectively than that of oven dry method. Moisture measurement by these methods can lead to wide variations of conclusion. Moisture measurement by John Deere moisture meter is quicker and easier than Moisture Probe and RiceterL (MM). However, adjustment procedure with respect to calibration is needed before use.Progressive Agriculture 27 (4): 511-516, 2016

Published: April 2017

Abstract
We present results from MMT/Hectochelle spectroscopy of 390 red giant candidate stars along the line of sight to the recently discovered Galactic satellite Crater 2. Modeling the joint distribution of stellar positions, velocities, and metallicities as a mixture of Crater 2 and Galactic foreground populations, we identify ∼62 members of Crater 2, for which we resolve a line-of-sight velocity dispersion of

=

km s−1 and a mean velocity of

=

km s−1 (solar rest frame). We also resolve a metallicity dispersion of

=

dex and a mean of

=

dex that is 0.28 ± 0.14 dex poorer than estimated from photometry. Despite Crater 2's relatively large size (projected halflight radius R
h ∼ 1 kpc) and intermediate luminosity (M

V
∼ −8), its velocity dispersion is the coldest that has been resolved for any dwarf galaxy. These properties make Crater 2 the most extreme low-density outlier in dynamical as well as structural scaling relations among the Milky Way’s dwarf spheroidals. Even so, under assumptions of dynamical equilibrium and negligible contamination by unresolved binary stars, the observed velocity distribution implies a gravitationally dominant dark matter halo, with a dynamical mass of

M
⊙ and a mass-to-light ratio of

enclosed within a radius of ∼1 kpc, where the equivalent circular velocity is

Log-normal Star Formation Histories in Simulated and Observed Galaxies
Authors: Diemer Benedikt , Sparre Martin , Abramson Louis E. , Torrey Paul 
Published: April 2017

Abstract
Gladders et al. have recently suggested that the star formation histories (SFHs) of individual galaxies are characterized by a log-normal function in time, implying a slow decline rather than rapid quenching. We test their conjecture on theoretical SFHs from the cosmological simulation Illustris and on observationally inferred SFHs. While the log-normal form necessarily ignores short-lived features such as starbursts, it fits the overall shape of the majority of SFHs very well. In particular, 85% of the cumulative SFHs are fitted to within a maximum error of 5% of the total stellar mass formed, and 99% to within 10%. The log-normal performs systematically better than the commonly used delayed-τ model, and is superseded only by functions with more than three free parameters. Poor fits are mostly found in galaxies that were rapidly quenched after becoming satellites. We explore the log-normal parameter space of normalization, peak time, and full width at half maximum, and find that the simulated and observed samples occupy similar regions, though Illustris predicts wider, later-forming SFHs on average. The ensemble of log-normal fits correctly reproduces complex metrics such as the evolution of Illustris galaxies across the star formation main sequence, but overpredicts their quenching timescales. SFHs in Illustris are a diverse population not determined by any one physical property of galaxies, but follow a tight relation, where

. We show that such a relation can be explained qualitatively (though not quantitatively) by a close connection between the growth of dark matter halos and their galaxies.
Planetesimal Formation by the Streaming Instability in a Photoevaporating Disk
Authors: Carrera Daniel , Gorti Uma , Johansen Anders , Davies Melvyn B. 
Published: April 2017

Abstract
Recent years have seen growing interest in the streaming instability as a candidate mechanism to produce planetesimals. However, these investigations have been limited to small-scale simulations. We now present the results of a global protoplanetary disk evolution model that incorporates planetesimal formation by the streaming instability, along with viscous accretion, photoevaporation by EUV, FUV, and X-ray photons, dust evolution, the water ice line, and stratified turbulence. Our simulations produce massive (60–130 M
⊕) planetesimal belts beyond 100 au and up to ∼20 M
⊕ of planetesimals in the middle regions (3–100 au). Our most comprehensive model forms 8 M
⊕ of planetesimals inside 3 au, where they can give rise to terrestrial planets. The planetesimal mass formed in the inner disk depends critically on the timing of the formation of an inner cavity in the disk by high-energy photons. Our results show that the combination of photoevaporation and the streaming instability are efficient at converting the solid component of protoplanetary disks into planetesimals. Our model, however, does not form enough early planetesimals in the inner and middle regions of the disk to give rise to giant planets and super-Earths with gaseous envelopes. Additional processes such as particle pileups and mass loss driven by MHD winds may be needed to drive the formation of early planetesimal generations in the planet-forming regions of protoplanetary disks.
A study on inflation credibility among students at the University of Pretoria
Authors: Rossouw Jannie , Padayachee Vishnu 
Published: April 2017

Following on five pilot studies on inflation credibility in South Africa aimed at the construction of inflation credibility barometers and a literature review of the international measurement of inflation perceptions, this paper reports the findings of a study on inflation credibility among 493 students at the University of Pretoria. Credibility barometers are reported for different genders, for Asians, blacks, coloureds and whites, and for students in different faculties. The main conclusions are that the inflation perceptions by the different genders in this study do not correspond with international experience in this regard; international use of inflation barometers will ensure comparability of inflation credibility; and that inflation-targeting countries should sample inflation credibility and calculate an inflation credibility barometer.
The ecological and economic consequences of changing land use in the southern Drakensberg grasslands, South Africa
Authors: Turpie JK , O'Connor T , Mills A , Robertson H 
Published: April 2017

The grassland biome of the southern Drakensberg region of South Africa is characterized by a relatively rich floral biodiversity, including a high level of endemics. Land use in the area was traditionally dominated by livestock ranching based mainly on indigenous grassland that conserved biodiversity to some degree. Currently however, market demands and risk factors are shifting land use in the area to a matrix of beef, cropping, dairy and particularly, towards plantation forestry. A spreadsheet model was constructed to understand how expected land use conversion will likely influence the biodiversity, and consequently, the total economic value (TEV) of the area. Six scenarios of increasing dairy and forestry intensification were modelled that incorporated biophysical and legal constraints to development. Results indicate that enhanced development is likely to have significant negative biodiversity impacts including the reduction of the alpha diversity of the indigenous plants in the region, a diminished local invertebrate diversity, an increase in invasions, and could also jeopardize the long term survival of the rare Wattled Crane and Oribi. Furthermore, while the direct use value derived from agriculture and forestry increases with increasing development, its negative influence on the indirect value of water runoff, by far the greatest value of the area, is sufficient to potentially offset the benefits. Other major direct-use, indirect-use, option and existence values are also considered.
Non-tariff barriers faced by South African firms: Are there any lessons?
Authors: Koch SF , Peet MA 
Published: April 2017

Exports and export growth are cornerstones of South African economic development policy, although they are not explicitly mentioned in ASGISA. One implication of an export-orientated economy is that many of its exporters must, of necessity, conform to the technical requirements in export markets. Here, it is shown that local exporters, particularly smaller firms, often incur export delays associated with meeting foreign technical requirements. The research, therefore, supports policies aimed at increasing the use of local conformity- assessment activities and improving information availability for local firms looking to meet foreign technical requirements.
The experience of work-life interaction in the Northern Cape mining industry: an exploratory study
Authors: Jacobs Dezré , Mostert Karina , Pienaar Jaco 
Published: April 2017

The objective of this research was to investigate how Afrikaans and Setswana employees in the Northern Cape mining environment experience the interaction between their work and personal lives and to determine which major strategies employees use to deal with work-life interaction (WLI). A non-probability purposive voluntary sample of 25 mineworkers was taken in the Northern Cape Province. Male and female participants were stratified in terms of language (Afrikaans and Setswana) and interviews were conducted with them. Interview questions focused on the main interacting dimensions in the lives of mineworkers and major strategies that employees use to deal with WLI. Content analyses were used to analyse the data. Several preceding factors (like work pressure, heavy workload, stress, and family obligations) that led to definite consequences (e.g. lack of quality time for self and family, physical and emotional strains, and low levels of productivity), as well as coping strategies (e.g. prioritising, time management, communication, and planning) were explored during the interviews. Although there were similarities, it seemed that there were definite differences between gender and language groups regarding their experiences of WLI.
Risk and FDI flows to developing countries
Authors: Van Wyk Jay , Lal Anil 
Published: April 2017

The explanatory power of institutional and macroeconomic variables for FDI stock accumulation in developing countries is investigated. Hypotheses are tested by means of pooled least squares regressions. The impact of institutional variables on FDI flows produced mixed results: levels of economic freedom facilitate inward FDI; political risk dampens investment. Some macroeconomic variables displayed significant explanatory power: market size (as measured by per capita income in the base year) and absolute growth of GDP positively impacts FDI inflows. Other key macroeconomic variables, such as lower current account balance, appreciation of host country’s currency, and lower inflation rate stimulate FDI inflows.
Factors affecting forward pricing behaviour: implications of alternative regression model specifications
Authors: Jordaan Henry , Grové Bennie 
Published: April 2017

Price risk associated with maize production became a reason for concern in South Africa only after the deregulation of the agricultural commodities markets in the mid-1990s, when farmers became responsible for marketing their own crops. Although farmers can use, inter alia, the cash forward contracting and/or the derivatives market to manage price risk, few farmers actually participate in forward pricing. A similar reluctance to use forward pricing methods is also found internationally. A number of different model specifications have been used in previous research to model forward pricing behaviour which is based on the assumption that the same variables influence both the adoption and the quantity decision. This study compares the results from a model specification which models forward pricing behaviour in a single-decision framework with the results from modelling the quantity decision conditional to the adoption decision in a two-step approach. The results suggest that substantially more information is obtained by modelling forward pricing behaviour as two separate decisions rather than a single decision. Such information may be valuable in educational material compiled to educate farmers in the effective use of forward pricing methods in price risk management. Modelling forward pricing behaviour as two separate decisions is thus a more effective means of modelling forward pricing behaviour than modelling it as a single decision.
Application of the Attitude Toward Enterprise (ATE) test on scondary school learners in South Africa
Authors: Van der Merwe Stephan P , Steenekamp Andre G , Athayde Rosemary 
Published: April 2017

The main aim of this research paper was to discuss the application of the Attitude Toward Enterprise (ATE) Test1 developed by Kingston University, London on secondary school learners in South Africa. A total of 1 748 usable questionnaires were gathered from grade 10 learners in the Sedibeng District and utilised for statistical analysis. Five factors with eigen-values greater than one describing the entrepreneurial attitudes of young learners were extracted during exploratory factor analysis. Tests for reliability and construct correlation produced satisfactory results to recommend the Enterprise Attitude Questionnaire for further use on young learners in South Africa. A comparison of the mean differences between the constructs for demographic variables produced statistically significant differences in a number of instances, but no visible effects or practical significance to suggest that these differences have any effect in practice. Practical recommendations are offered for further employment of the Enterprise Attitude Questionnaire in entrepreneurship research on young learners.
The cost-effectiveness of intervening in low and high HIV prevalence areas in South Africa
Authors: Mbonigaba Josue 
Published: April 2017

This research compared the cost-effectiveness of a set of HIV/AIDS interventions in a low HIV prevalence area (LPA) and in a high HIV prevalence area (HPA) in South Africa. The rationale for this analysis was to assess the interaction dynamics between a specific HIV/AIDS intervention and an area of implementation and the effects of these dynamics on the cost-effectiveness of such an HIV/AIDS intervention. A pair of Markov models was evaluated for each intervention; one model for a HPA and another for an LPA and the cost-effectiveness of that intervention was compared across an LPA and a HPA. The baseline costs and health outcomes in each area were collected from the literature. To depict interaction dynamics between an HIV/AIDS intervention and an area of implementation, baseline health outcomes collected in each area, were adjusted over time based on the patterns of the projections observed in the AIDS model of the Actuarial Society of South Africa (ASSA2008). The study found that the VCT and treatment of STDs were equally cost-effective in an LPA and in a HPA while PMTCT and HAART were more cost-effective in an LPA than in a HPA. As a policy proposal, resources earmarked to non-ARV based interventions (VCT and treatment of STDs) should be equally shared across an LPA and a HPA while more of the resources reserved for ARV-based interventions (PMTCT and HAART) should go in an LPA in order to increase efficiency.
Where the two logics of institutional theory and entrepreneurship merge: are family businesses caught in the past or stuck in the future?
Authors: Brundin Ethel , Vigren-Kristoferson Caroline 
Published: April 2017

The aim of this article is to investigate how owners of family businesses combine their traditional heritage with changes in a new competitive arena. This is done by allowing the owners and managers of six vineyards to give voice to their concerns about the past, present, and future. The findings suggest that family businesses in the South African wine industry are subject to a process of institutionalisation in which entrepreneurial activities, which are part of this process, may not be as entrepreneurial as they appear at first. It is found that the two forms of logic behind the institutionalisation of the family firm and entrepreneurial activities in the context of the post-apartheid era can be successfully merged. Theoretical and practical implications bring the article to a close.
