Published: January 2018

AbstractIn this era of a data-driven society, useful data (Big Data) is often unintentionally ignored due to lack of convenient tools and expensive software. For example, web log files can be used to identify explicit information of browsing patterns when users access web sites. Some hidden information, however, cannot be directly derived from the log files. We may need external resources to discover more knowledge from browsing patterns. The purpose of this study is to investigate the application of web usage mining based on web log files. The outcome of this study sets further directions of this investigation on what and how implicit information embedded in log files can be efficiently and effectively extracted. Further work involves combining the use of social media data to improve business decision quality.

Abstract
A Soil and Water Assessment Tool (SWAT) model was used to model streamflow in a tropical humid basin in the Cerrado biome, southeastern Brazil. This study was undertaken in the Upper São Francisco River basin, because this basin requires effective management of water resources in drought and high-flow periods. The SWAT model was calibrated for the period of 1978–1998 and validated for 1999–2007. To assess the model calibration and uncertainty, four indices were used: (a) coefficient of determination (R2); (b) Nash–Sutcliffe efficiency (NS); (c) p-factor, the percentage of data bracketed by the 95% prediction uncertainty (95PPU); and (d) r-factor, the ratio of average thickness of the 95PPU band to the standard deviation of the corresponding measured variable. In this paper, average monthly streamflow from three gauges (Porto das Andorinhas, Pari and Ponte da Taquara) were used. The results indicated that the R2 values were 0.73, 0.80 and 0.76 and that the NS values were 0.68, 0.79 and 0.73, respectively, during the calibration. The validation also indicated an acceptable performance with R2 = 0.80, 0.76, 0.60 and NS = 0.61, 0.64 and 0.58, respectively. This study demonstrates that the SWAT model provides a satisfactory tool to assess basin streamflow and management in Brazil.

Abstract
Countercurrent–cocurrent dissolved air flotation (CCDAF), the popular water purification device, which consists of collision and adhesion contact zones, showed favorable flotation conditions for micro-bubble adhesion and stability. In this study, computational fluid dynamics (CFD) numerical simulation was employed to confirm that the unique CCDAF configuration create reasonable and that the flow field characteristics were good no matter for single phase or gas–liquid two-phase conditions. In addition, the turbulence of the flow field was enhanced with the increasing influent load; the swirling was remarkably reduced with the increase of gas holdup. Meanwhile, a thick micro-bubble filter layer was formed in the separation zone, which favored bubble-flocs agglomerating and rising. The force analysis also showed that the cross section within the tank contribute to the uniformity of the bottom water collection as well as enlargement of the bottom outflow area, therefore improving the overall flotation performance. The simulation results revealed for the CCDAF process can provide technical guidance for engineering design and application.
Políticas mercantiles en espacios reduccionales fronterizos: Modelos, reapropiaciones y disputas (Río de la Plata, siglo XVIII)
Authors: Quarleri Lía 
Published: January 2018

El objetivo del artículo es analizar el modelo mercantil de intervención borbónica en las reducciones guaraníes atendiendo a las adaptaciones, respuestas y conflictos derivados. La metodología utilizada es el análisis de fuentes históricas desde una perspectiva antropológica. En primer lugar, se esclarecieron las directrices borbónicas del libre comercio en las misiones guaraníes. En segundo lugar, se plasmaron las controversias existentes entre las autoridades coloniales. Por último, se dieron indicios de la participación indígena en dicho comercio. Las limitaciones estuvieron dadas por el sesgo de las propias fuentes oficiales. El valor del estudio reside en la realización de un análisis articulado a partir de las normativas, los conflictos y la agencia indígena. Se llegó a la conclusión de que la intermediación política configurada para obstruir el libre acceso de la población misionera al nuevo sistema mercantil generó un proceso contrario. Asimismo, que este proceso se dio dentro de un poder colonial fragmentado.

Authors: Baioun Abeer , Kellawi Hassan , Falah Ahamed 
Published: January 2018

Background:
Demands of rechargeable energy storage devices such as batteries are increasing.
Potassium is cheap and abundant contrary to Li. Prussian blue and analogues PBAs are
promising cathodes materials for K- ion batteries, because of facile synthesis and low cost. However,
PB and close analogues (Prussian green and Prussian white) suffer from low coulombic efficiency
and low cyclability owing to structure deficiency. We present here a facile synthesis dip-dry method
at elevated temperature of Prussian yellow film cathode for aqueous potassium battery with Zn anode.
The device exhibits a high specific capacity, coulombic efficiency and long cycling life with
satisfactory charge/discharge behavior.

Method:
Prussian yellow(PY) film was prepared as a thin film on ITO substrate by dip dry method
from a solution mixture of Fe3+ (0.1M) and Fe(CN)-6 (0.1M) at (80°C). Precipitation time was fifteen
minutes. Films where characterization by FTIR, TGA, XRD, EDS, SEM, CV and EIS. Batteries
composed of PY cathode and zinc metal anode were tested in 0.1M KCl electrolyte.

Results:
Battery gave OCV 1.9V with specific capacity of 142 mAh/g at rate of (~ 3C), with satisfactorily
cycling ability up to 500 cycles & reversible charge/discharge behavior. Good crystal structure
of PY film was demonstrated by several characterization methods e.g., FT-IR, TGA, XRD, EDS,
SEM and electrochemical techniques. All showed good crystallinity quality of prepared PY films
which demonstrate cathode qualities K cathode for K charge / discharge battery.

Conclusion:
Prussian yellow film, one of Prussian blue close analogues prepared in a simple and
very facile nonelectrical method can be used as a robust cathode with highly reversible redox reactions
that enable this material to be used as a cathode in battery of potassium aqueous electrolyte
with Zinc anode. Battery has a significant cycle life (~500 cycle) and satisfactory capacity of
142mAhg-1 at rate of (~3C) with efficiency retention of 82%.
Realising the Public Potential of Corporate Law: Twenty Years of Civil Penalty Enforcement in Australia
Authors: Welsh Michelle 
Published: January 2018

AbstractTraditionally corporate law has been viewed as having characteristics that are commonly associated with private law. Largely this view developed as a result of the “law and economics” scholarship which dominated the corporate law debate, especially in the United States, in the last quarter of last Century. While the traditional “law and economics” approach supports the view that corporate law should be treated as a branch of private law, and that the state should have no role in its enforcement, other scholars, particularly those that adopt a progressive approach, argue that corporate law has, and should be recognised as having characteristics that are usually associated with public law. Arguably, an area of Australian corporate law that displays characteristics that are usually associated with public law is the statutory directors’ duties and the civil penalty regime that supports them. This enforcement regime gives the state through the corporate regulator, standing to take court based proceedings to enforce what are in effect, contracts that established corporate governance structures.This article seeks to determine the appropriate role of a public regulator in these circumstances. The questions considered are: whose interests should the public regulator represent when it is tasked with the responsibility of enforcing the statutory directors’ duties that largely codify fiduciary and common law duties? Given that the duties are owed by directors to their company should the primary role of the public regulator be to represent the interests of the company, and its shareholders, who have suffered a loss as a result of the alleged contravention of the directors’ duties or should the primary role of the public regulator be to act in the interests of the members of the larger community? In these situations what are the interests of the larger community? Drawing on regulatory theory the argument advanced in this paper is that despite the fact that the statutory directors’ duties codify what are in effect private rights between directors and their companies, the primary role of a public regulator is not to utilise the enforcement mechanisms at its disposal in order to obtain compensation for companies who have suffered a loss. Rather, the regulator's primary role is to act in the interests of the larger community by utilising the enforcement mechanisms at its disposal strategically in order to encourage greater compliance.
Animal Welfare and the WTO: The Legality and Implications of Live Export Restrictions under International Trade Law
Authors: Chaudhri Radhika 
Published: January 2018

AbstractIn Australia, controversial incidents regarding the treatment of live animals exported from Australia spark regular debate on whether the live export trade should be banned or more tightly regulated. Government responses to public outcry often take the form of restrictions on the trade of the animals concerned, but the legality of unilateral measures of this kind is yet to be directly considered by the World Trade Organization's Appellate Body. This article examines the legality of imposing restrictions on live export under the international trade law regime set up by the General Agreement on Tariffs and Trade 1994 (‘GATT’), and in particular, whether such measures could be justified under Article XX. In exploring this question, special attention is given to the Australian government's new regulatory framework, as introduced by the Export Control (Animals) Amendment Order 2012 (No 1), which imposes an exporter supply chain assurance obligation on Australian suppliers. In addition, in light of the continued calls from animal welfare groups to ban the trade entirely, the legality of a complete moratorium on live exports will also be considered. Although the exceptions in Articles XX(b) and XX(g) of the GATT appear to be relevant to live exports, ultimately any regulation might be best supported under the ‘public morals’ exception in Article XX(a). However, care will need to be taken in the design of any restriction to avoid breaching the strict chapeau requirements of Article XX.

Background and objectives
CKD is characterized by remarkably high hospitalization and readmission rates. Our study aim was to test a medication therapy management intervention to reduce subsequent acute care utilization.

Design, setting, participants, & measurements
The CKD Medication Intervention Trial was a single-blind (investigators), randomized clinical trial conducted at Providence Health Care in Spokane, Washington. Patients with CKD stages 3–5 not treated by dialysis who were hospitalized for acute illness were recruited. The intervention was designed to improve posthospitalization care by medication therapy management. A pharmacist delivered the intervention as a single home visit within 7 days of discharge. The intervention included these fundamental elements: comprehensive medication review, medication action plan, and a personal medication list. The primary outcome was a composite of acute care utilization (hospital readmissions and emergency department and urgent care visits) for 90 days after hospitalization.

Results
Baseline characteristics of participants (n=141) included the following: age, 69±11 (mean±SD) years old; women, 48% (67 of 141); diabetes, 56% (79 of 141); hypertension, 83% (117 of 141); eGFR, 41±14 ml/min per 1.73 m2 (serum creatinine–based Chronic Kidney Disease Epidemiology Collaboration equation); and urine albumin-to-creatinine ratio median, 43 mg/g (interquartile range, 8–528) creatinine. The most common primary diagnoses for hospitalization were the following: cardiovascular events, 36% (51 of 141); infections, 18% (26 of 141); and kidney diseases, 12% (17 of 141). The primary outcome occurred in 32 of 72 (44%) of the medication intervention group and 28 of 69 (41%) of those in usual care (log rank P=0.72). For only hospital readmission, the rate was 19 of 72 (26%) in the medication intervention group and 18 of 69 (26%) in the usual care group (log rank P=0.95). There was no between-group difference in achievement of guideline-based goals for use of renin-angiotensin system inhibition or for BP, hemoglobin, phosphorus, or parathyroid hormone.

Conclusions
Acute care utilization after hospitalization was not reduced by a pharmacist-led medication therapy management intervention at the transition from hospital to home.

Background: There is evidence that oxidative stress plays an important role in autoimmune diseases, such as rheumatoid arthritis (RA). Despite the supporting evidence for a beneficial effect of antioxidants on clinical characteristics of RA, the right balance for optimal effectiveness of antioxidants is largely unknown. A study was designed to determine the potential beneficial effects of antioxidant intervention on clinical parameters of RA.Methods: Randomized clinical trial of 152 patients with positive rheumatoid factor (RF) and a Disease Activity Score (DAS 28) higher than 3.2 were enrolled in the study. Patients were divided into two groups (Group A and Group B) randomly and group A received methotrexate and antioxidant vitamins (A, C and E in a fixed dose) and group B methotrexate only. They were followed up for three visits (baseline, 10th week and 14th week). The intervention was stopped after 10 weeks and was followed by a ‘wash-out’ period of 4 weeks. At baseline, 10th week and 14th week patient’s condition were assessed by means of DAS-28 score. P- Value less than <0.05 was considered significant.Results: The numbers of swollen and tender joints were significantly reduced and general health was improved reflected by improved DAS-28 score at 10th week.The antioxidant effect was considered beneficial as compared to the scores of 1st visit at baseline; the DAS-28 score was significantly reduced at 2nd visit at 10th week. Increment of the DAS-28 score among the group A patients who were on antioxidant up to10 weeks, after the “wash-out period” of four weeks i.e. at 14th week confirmed a significant relation between changes in clinical condition and antioxidants.Conclusion: This study was designed to assess the potential beneficial effect of antioxidants (Vitamin A, C and E) in combination with methotrexate in the treatment of RA.

Authors: Toruan Lumban Nauli Lumban , Soedharma Dedi , Dewi Kresna Tri 
Published: January 2018

Composition and distribution of foraminifers are affected by human activities and have close association with coral reef ecosystem. The aims of this research were to investigate the benthic foraminifers’ composition and distribution in sediment of coral reef ecosystem. Eleven stations of Karang Bongkok, Pramuka, and Onrust Island were observed in this study. The sediments were taken from surface substrate up to 2 cm under the substrate. Samples were washed on sieve with mesh size 0,063 mm, and then dried in oven with 50°C of temperature for two hours. After separating from the sediment, the foraminifers were laid on foraminiferal slide and indentified using binocular microscope. The highest composition of symbiont-bearing foraminiferal assemblages which associated with reef ecosystem was in East Pramuka (78.17%) and the lowest was in South Onrust (21,83%). The opportunistic type had the highest composition in South Onrust (38.67%) and the lowest was in South Karang Bongkok. In west Pramuka had the highest composition of heterotrophic type (57.17%) and the lowest was in North Onrust (11.33%). Onrust Island was dominated by opportunistic type, indicating high nutrient. The highest amount of foraminifers’ taxa was found in Karang Bongkok with good coral reef coverage, while the lowest in Onrust facing with Jakarta Bay. Keywords: composition, distribution, benthic foraminifers, coral reef.
