extended Farm Site Development Method
Authors: Hanekom Eugene , Liebenberg Andre , De Vries Marné 
Published: September 2016

The inefficient and ineffective use of arable land in South Africa is one of the numerous challenges within its agricultural sector. Previous research has indicated that a method, the Farm Site Development Method (FSDM), could increase the effective and efficient use of arable land by providing a roadmap to the farm owner for incrementally transforming the current state facilities and resources of a farm towards a future saturation state. The FSDM was then demonstrated at a crop-producing farm and several opportunities existed to extend its utility. Here we suggest its extension for application to a livestock farm, and also include optimisation techniques, demand planning and financial planning.

Significance:

Extension of the Farm Site Development Method, and its demonstration at a livestock farm, for facilities and financial planning within the agricultural sector.
Pesticide management practices among rural market gardening farmers near Harare, Zimbabwe
Authors: Zimba Moses , Zimudz Clemence 
Published: September 2016

In 2014, we carried out a survey in Chinamhora and Chihota communal lands on the outskirts of Harare city, with the aim of understanding pesticide management practices among market gardening farmers. The farmers grew vegetables that mostly included tomatoes, cabbages, rape, cucumbers, onions and carrots, and they used mainly organophosphates and pyrethroids to control pests. A questionnaire was administered to 119 male heads of households across both study areas. The questionnaire contained 13 closed-ended questions in three sections: source and quality of pesticides, handling and use, and storage and disposal of pesticides used to protect crops. The study identified numerous gaps related to the handling of pesticides. Although the quality of labelling and packaging can largely identify the quality of pesticide, most of the farmers (77.3%) could not distinguish between genuine and counterfeit pesticides; approximately half (47.9%) of the farmers were not concerned about expiry dates; 27% did not observe post-spray periods; and 63% did not take precautions according to colour-coding of the pesticides. Also of concern were the large numbers of farmers who were not using protective coveralls (54.3%); a substantial number who were not using knapsacks for spraying (21.8%); poor storage of the pesticides, as shown by the variation in storage facilities; the use of empty pesticide containers for domestic purposes (20.2%); and lack of strict adherence to recommended dose levels, with some farmers (28.6%) merely estimating the dilution of pesticides. Training through outreach programmes is recommended.

Significance:

Identifies gaps in the way pesticides are used and stored by rural market gardening farmers.
Highlights the need for government agricultural extension workers to hold regular workshops for farmers.
Indicates the need for government ministries to monitor counterfeit pesticides.

NOTAS SOBRE A QUESTÃO DA SINGULARIDADE DA FALA DA CRIANÇA
Authors: Carvalho Glória Maria Monteiro de 
Published: September 2016

Neste artigo, coloca-se em discusão o caráter singular da fala da criança, no momento de mudança da condição de infans à condição de falante, sendo a singularidade concebida como uma transgressão, uma ruptura de padrões da língua. A fim de atribuir um estatuto teórico à referida concepção, é destacada a noção de anagrama que provoca uma ruptura no significante conforme instituído por Saussure. Estendendo essa noção à fala infantil, são abordados fragmentos de enunciados produzidos por uma criança em um momento inicial de sua trajetória linguística. A partir de tal abordagem, propõe-se, então, que a escuta da singularidade da fala infantil, pelo investigador, implicaria a escuta de uma transgressão da linearidade do significante da fala do outro/falante.
A New Analytic Solution for Finite Conductivity Vertical Fractures With Real Time and Laplace Space Parameter Estimation
Authors: Lee Sheng-Tai , Brockenbrough John 
Published: September 2016

ABSTRACT
A new analytic solution, based on a trilinear flow model, is developed to study the transient behavior of a well intercepted by a finite-conductivity vertical fracture. The solution takes into account the effects of skin, wellbore storage, and fracture diffusivity. Both constant pressure and constant rate cases are considered. The solution is simple and reliable for short time analysis of the system of interest. Combining this solution with the well-known semi-log asymptotic solution provides a reliable tool for formation evaluation of fractured wells. We have also demonstrated that the optimization technique is a convenient means of reservoir parameter estimation in real time and Laplace spaces. For the problem examined in this paper, real time parameter estimation is found to be more convenient than Laplace space parameter estimation. A set of early-time asymptotic solutions is also presented. Our results indicate that if the wellbore storage effect is absent but a skin exists, then the fracture diffusivity will influence the early time data. Also if both the skin and storage effects are present, then the early time data alone cannot provide a unique determination of skin and other reservoir parameters.
A Structured Mobility-Based Methodology for Quantification of Net-Pay Cutoff in Petroleum Reservoirs
Authors: Saboorian-Jooybari Hadi 
Published: September 2016

Summary
Petrophysical cutoffs of a hydrocarbon reservoir are among the key parameters to determine net pay, net-to-gross ratio (NTG), original hydrocarbon(s) in place (OHIP), and reserves estimation. Although the concept of cutoffs has been continuously used since the 1950s, so far there is no universal agreement on their definition and quantification methods. In the most commonly used procedure, log-derived shale-volume faction (Vsh), porosity (ϕ), and water saturation (Sw) are tied back to experimentally measured rock permeability (k) values through a porosity/permeability crossplot. Then, limiting values of the three log-derived parameters are determined by use of fixed-permeability-cutoff values of 1 and 0.1 md for oil and gas reservoirs, respectively. Although these values, which are usually referred to as rule-of-thumb cutoffs, seem to be appropriate in some reservoirs, they can be misleading in most cases (e.g., tight gas and heavy oil). Furthermore, these fixed values have no mathematical basis because they were founded mainly on the basis of the experience in a number of typical reservoirs. Therefore, application of the rule-of-thumb cutoffs may cause significant errors in evaluation of petroleum reservoirs.
This study focuses on technical and economic factors that have to be considered for delineating net pay. Mobility cutoff in this paper is founded on the flow equation (Darcy's law) and combined with economic-profitability condition to quantify the cutoff individually in gas and oil reservoirs. Thereafter, a novel structured procedure is provided to integrate all core, petrophysical, and fluid data with the calculated mobility cutoff, thereby introducing a single permeability cutoff for the reservoir. One of the advantages of the new procedure over the traditional methodologies is that once a cutoff is determined for permeability, it does not require subsequent tying back to ϕ,Vsh, and Sw to quantify the extra discrete cutoffs. In addition, the technique benefits from the use of permeability distribution within the reservoir in cutoff quantification. The procedure is simple, straightforward, general, and practically rationalized. Despite the previous works, it is noteworthy to mention that the newly developed approach is applicable to all types of hydrocarbon reservoirs, including typical reservoirs, tight oil and gas reservoirs, heavy-oil reservoirs, laminated-thin-bed reservoirs, and discrete stacked reservoirs, with wide ranges of rock and fluid properties. An example calculation is presented for application of the methodology in an Iranian carbonate reservoir. The example clearly illustrates how all available data from a reservoir should be integrated for appropriate determination of the permeability cutoff.

Resumen: Las periferias de América Latina se caracterizan por sus genes tipológicos informales (invasiones) que identifican la urbanización de la pobreza y que se transforman en territorio insostenible. El objetivo principal de estudio, analizar las características de las periferias internas informales latinoamericanas en un escenario marcado por las ciudades difusas, que al menos nos disponga ante algunos aspectos que afectan a las sociedades del siglo XXI. La investigación es descriptiva y analítica, sigue pautas holísticas, que reflejan el comportamiento del hombre, el estado real del territorio, la teoría del principio de incertidumbre, del caos, aporta nuevas ideas para el mejoramiento o coacción de los aspectos urbanos y ambientales. La ciudad de Medellín es el territorio escogido para investigar las características de los asentamientos espontáneos. El resultado nos originó otra manera de aproximación al problema, dejando de lado las soluciones basadas en el equilibrio social (igualdad) y en el orden (control), para transformarlas en territorios sustentables.

Cultural Adaptation of Minimally Guided Interventions for Common Mental Disorders: A Systematic Review and Meta-Analysis
Authors: Harper Shehadeh Melissa , Heim Eva , Chowdhary Neerja , Maercker Andreas , Albanese Emiliano 
Published: September 2016

Background
Cultural adaptation of mental health care interventions is key, particularly when there is little or no therapist interaction. There is little published information on the methods of adaptation of bibliotherapy and e-mental health interventions.

Objective
To systematically search for evidence of the effectiveness of minimally guided interventions for the treatment of common mental disorders among culturally diverse people with common mental disorders; to analyze the extent and effects of cultural adaptation of minimally guided interventions for the treatment of common mental disorders.

Methods
We searched Embase, PubMed, the Cochrane Library, and PsycINFO for randomized controlled trials that tested the efficacy of minimally guided or self-help interventions for depression or anxiety among culturally diverse populations. We calculated pooled standardized mean differences using a random-effects model. In addition, we administered a questionnaire to the authors of primary studies to assess the cultural adaptation methods used in the included primary studies. We entered this information into a meta-regression to investigate effects of the extent of adaptation on intervention efficacy.

Results
We included eight randomized controlled trials (RCTs) out of the 4911 potentially eligible records identified by the search: four on e-mental health and four on bibliotherapy. The extent of cultural adaptation varied across the studies, with language translation and use of metaphors being the most frequently applied elements of adaptation. The pooled standardized mean difference for primary outcome measures of depression and anxiety was -0.81 (95% CI -0.10 to -0.62). Higher cultural adaptation scores were significantly associated with greater effect sizes (P=.04).

Conclusions
Our results support the results of previous systematic reviews on the cultural adaptation of face-to-face interventions: the extent of cultural adaptation has an effect on intervention efficacy. More research is warranted to explore how cultural adaptation may contribute to improve the acceptability and effectiveness of minimally guided psychological interventions for common mental disorders.
Audit Market Structure and Audit Pricing
Authors: Eshleman John Daniel , Lawson Bradley P. 
Published: September 2016

SYNOPSIS
Extant literature finds mixed evidence on the association between audit market concentration and audit fees. We re-examine this issue using a large sample of U.S. audit clients covering 90 metropolitan statistical areas (MSAs) spanning 2000–2013. We find that audit market concentration is associated with significantly higher audit fees, consistent with the concerns of regulators and managers. We also find that increases in audit market concentration are associated with fewer initial engagement fee discounts (i.e., reduced lowballing), particularly for non-Big 4 clients. We reconcile our findings with those of prior research and find that our divergent findings are attributable to controls for MSA fixed effects. In supplemental analyses, we find that audit market concentration is associated with higher audit quality. We also find that concentration is associated with higher audit quality for first-year engagements, but only if the auditor does not lowball on the engagement. Our results are relevant to the ongoing debate regarding the consequences of increased concentration within the U.S. audit market (GAO 2003, 2008).

Internal Control Weaknesses and Financial Reporting Fraud
Authors: Donelson Dain C. , Ege Matthew S. , McInnis John M. 
Published: September 2016

SUMMARY
This study examines whether and how weak internal controls increase the risk of financial reporting fraud by top managers. There is a longstanding debate on whether control strength significantly affects fraud risk, yet little evidence on this issue. Further, there is no evidence on the mechanism linking control strength to fraud risk. We find a strong association between material weaknesses and future fraud revelation. We theorize that this link could be attributable to weak controls (1) giving managers greater opportunity to commit fraud, or (2) signaling a management characteristic that does not emphasize reporting quality and integrity. We find support for the opportunity explanation, but not through specific accounts linked to control weaknesses. Instead, consistent with the PCAOB's assertion, weaknesses in entity-wide controls, not process-level controls, are associated with a higher risk of reporting fraud.
