Authors: Denez Marlon Dias , Bueno Adeney De Freitas , Pasini Amarildo , Bortolotto Orcial Ceolin , Stecca Cristiane Dos Santos
Published: July 2014

Biological parameters of Podisus nigrispinus (Dallas) fed with third-instar Lepidoptera larvae of Spodoptera frugiperda J.E. Smith, Spodoptera cosmioides (Walker, 1858), and Anticarsiagemmatalis (Hübner, 1818), as well as eggs of Euschistus heros (F., 1798), the brown stink bug, were evaluated. Experiments were performed under controlled conditions (25 ± 1°C; 70 ± 10% relative humidity, and a photoperiod of 16:8 [L:D] h). P. nigrispinus had good nymphal development with >87% larval survival (viability), as well as high fecundity in adults, when fed with A. gemmatalis, S.frugiperda, and S. cosmioides larvae. Differently, adults of P. nigrispinus originating from nymphs fed with eggs of E. heros completed their life cycle; however, larval survival (viability) was reduced to 45.7%. Furthermore, these adults did not oviposit, and their body mass was from 50 to 73% lower than in individuals originating from nymphs fed with other tested prey. Taking into consideration that neither E. heros nor Spodoptera spp. are controlled by Bt soybean varieties expressing the Cry 1Ac protein, it can be assumed that the predator P. nigrispinus will still find prey species to feed in soybean fields even after the adoption of this pest control technology. This might help lower any potential negative impact of Bt soybean adoption above this insect predator. Moreover, the studied caterpillars proved to be potential prey for the predator's mass rearing, similarly to what is presently being done with coleopteran larvae.

Published: July 2014

The purpose of this article is to describe a collaborative community project designed to enhance the mental health and development of children experiencing family homelessness. In spite of the many risk factors faced by children without homes, there has been limited attention to understanding and addressing their needs. Community Action Targeting Children who are Homeless (CATCH) was developed by a group of community leaders in family homelessness and experts in young children's mental health; the goal of CATCH is to promote the social–emotional adjustment and developmental status of children who are homeless. In this article we provide a rationale for the project, discuss the goals and strategies implemented to meet those goals, and describe the lessons learned.
Employer Perspectives on the Role of Soft Skills in Subsidized Employment Relationships
Authors: Carnochan Sarah , Taylor Sarah , Pascual Gina , Austin Michael J.
Published: July 2014

The dual objective of subsidized employment programs is to support employers and low-income job seekers. However, few studies of these programs have examined employer perspectives or reflected critically on the role of soft skills in relationships between employers and subsidized employees. This qualitative study examined employer perspectives on soft skills, drawing on the concept of fit from the person-in-environment perspective, as framed by personnel psychology, to interpret the findings. Employers emphasized the importance of motivation, self-presentation, and interpersonal skills. They described the effect of these characteristics and behaviors on workplace interactions, as they sought employees whose similarity offered a supplementary fit. The findings suggest recommendations for improving subsidized employment programs, as well as implications for social work education and research.
Crack propagation in the cyclic semi-circular bending test
Authors: Lancaster Ian M. , Khalid H. A.
Published: July 2014

Results are presented to describe crack propagation response in conventional and polymer-modified asphalt mixtures. The fracture characteristics of eight mixtures containing increasing amounts of poly(styrene-butadiene-styrene) (SBS) co-polymer are investigated under cyclic semi-circular bending conditions. Analysis based on Schapery's correspondence principle enables the conversion of the Paris Law from its classic linear elastic domain to elasto-plastic analysis adopting a generalised J-integral approach. Creep compliance is one of the material's intrinsic properties determined in the study to aid in achieving the domain conversion. This is measured on small cylindrical samples of the studied mixtures using a dynamic shear rheometer within the linear viscoelastic range. Results, expressed in terms of Paris Law pseudo-constants, are used to gauge the material's resistance to crack propagation where no clear correlations are found to the degree of polymer modification. Crack propagation in a typical UK pavement construction is modelled using the classic Paris Law and J-integral approaches.
The impact of European standards and CE marking on asphalts
Authors: Walsh Ian D.
Published: July 2014

Over the last few years significant changes have taken place in the way that asphalt and other surfacing materials are specified and their manufacture and installation are quality controlled. European standards and the accompanying legally enforceable CE marks listing test results are now ubiquitous. Although previous UK quality assurance initiatives on products existed, CE marking introduces new rigorousness. CE marking does not apply to installation and the UK has a comprehensive series of national highway schemes to monitor and improve quality, not least by the requirement for demonstrably competent staff and operatives. As a result of these initiatives site supervision and testing by clients has reduced, and some bemoan and fear the effect of the loss of client expertise. The paper makes some suggestions.
Hygroscopic moisture content: determination and correlations
Authors: Prakash K. , Sridharan A. , Sudheendra S.
Published: July 2014

Hygroscopic moisture content of fine-grained soil represents the water adsorbed by the negatively charged clay platelets when the oven-dried soil is exposed to an atmosphere with different levels of humidity, which is a variable. Hygroscopic moisture content has been linked with many clay mineralogical parameters in predictive geotechnical engineering. However, there appears to be no standard codal provisions to quantify this property. This paper uses the modified rectangular hyperbolic representation of the adsorbed water content against time of exposure to an environment with 100% relative humidity relationship to quantify the hygroscopic moisture content. The proposed method is very simple and fairly accurate. The hygroscopic moisture contents so predicted corresponding to 100% relative humidity have been shown to have one-to-one correspondence with the values obtained through actual time-consuming measurements. By virtue of common dependency factors, it is shown that the hygroscopic moisture content at 100% relative humidity of fine-grained soils can be uniquely related with their liquid limits and equilibrium sediment volumes. Furthermore, instead of a time-consuming method of determining the hygroscopic moisture content, a simple method of predicting the same knowing their liquid limits has been proposed.
Real-time process dynamics monitoring in Anammox reactors
Authors: Alpaslan Kocamemi B. , Dityapak D.
Published: July 2014

Process dynamics in Anammox systems were evaluated through continuous monitoring of pH, oxidation reduction potential (ORP) and conductivity in two separate newly started-up sequencing batch reactors, one seeded with an enriched Anammox sludge and the other seeded with mixed activated sludge. The pH and ORP profiles exhibited characteristic patterns depending on the process dynamics during early start-up, start-up and enrichment phases of the operational period of 410 days. The simultaneously continuing processes of the start-up period showed apparent indicative trend lines in pH and ORP profiles. Conductivity profiles were consistent with the process dynamics in all phases. During the enrichment phase, conductivity decreases could quantitatively be related to process removal efficiencies and all real-time profiles exhibited specific break-points which coincided with the end of Anammox in each cycle. The end of Anammox was observed as an ‘apex’ on pH profiles and a ‘valley’ on ORP profiles. The ‘apex’ and ‘valley’ points exactly coincided with the end point of the linear decrease in the conductivity profiles. The overall findings suggested a great potential in using real-time pH, ORP and conductivity measurements for quick and reliable monitoring of Anammox systems during start-up and enrichment periods.
Treatment of iron(II)-rich acid mine water with limestone and oxygen
Authors: Mohajane G. B. , Maree J. P. , Panichev N.
Published: July 2014

The main components of acid mine water are free acid, sulphate, and Fe2+. Limestone is the most cost-effective alkali that can be used for neutralization. The purpose of this investigation was to identify conditions where Fe2+ is removed with limestone and simultaneously oxidized with oxygen to Fe3+, in a polyvinyl chloride pipe under pressure. Gypsum scaling is prevented by passing rubber balls through the pipe of the so-called Oxygen-Pipe-Neutralization (OPeN) process pilot plant. Two synthetic waters were treated: (A) acid mine water containing 123 mg L−1 Fe2+ representing gold mine water, and (B) acid mine water containing 6,032 mg L−1 Fe2+ representing coal mine water. Batch studies were carried out in a pipe reactor and showed that the rate of Fe2+ oxidation depended on the Fe2+concentration, oxygen pressure, amount of recycled sludge, limestone dosage and the mixing rate. Continuous studies in an OPeN process pilot plant resulted in 100% removal of total acidity from synthetic coal mine water and a 98% removal from synthetic gold mine water. Fe2+ was removed completely as precipitated Fe(OH)3 from both synthetic coal and gold mine water at around pH 7 at 200 and 100 kPa oxygen pressure, respectively.

Published: July 2014

The macro region of Campinas (Brazil) is rapidly evolving with new housing developments and industries, creating the challenge of finding new ways to treat wastewater to a quality that can be reused in order to overcome water scarcity problems. To address this challenge, SANASA (a publicly owned water and wastewater concessionaire from Campinas) has recently constructed the ‘EPAR (Water Reuse Production Plant) Capivari II’ using the GE ZeeWeed 500D® ultrafiltration membrane system. This is the first large-scale membrane bioreactor (MBR) system in Latin America with biological tertiary treatment capability (nitrogen and phosphorus removal), being able to treat an average flow of 182 L/s in its first phase of construction. The filtration system is composed of three membrane trains with more than 36,000 m2 of total membrane filtration area. The membrane bioreactor (MBR) plant was commissioned in April 2012 and the permeate quality has exceeded expectations. Chemical oxygen demand (COD) removal rates are around and above 97% on a consistent basis, with biochemical oxygen demand (BOD5) and NH3 (ammonia) concentrations at very low levels, and turbidity lower than 0.3 nephelometric turbidity unit (NTU). Treated effluent is sent to a water reuse accumulation tank (from where will be distributed as reuse water), and the excess is discharged into the Capivari River.

Published: July 2014

Stormwater runoff quality is sensitive to land use and land cover (LULC) change. It is difficult to understand their relationship in predicting the pollution potential and developing watershed management practices to eliminate or reduce the pollution risk. In this study, the relationship between LULC change and stormwater runoff quality in two separate monitoring sites comprising a construction area (Site 1) and mixed land use (Site 2) was analyzed using geographic information system (GIS), event mean concentration (EMC), and correlation analysis. It was detected that bare land area increased, while other land use areas such as agriculture, commercial, forest, grassland, parking lot, residential, and road reduced. Based on the analyses performed, high maximum range and average EMCs were found in Site 2 for most of the water pollutants. Also, urban areas and increased conversion of LULC into bare land corresponded to degradation of stormwater quality. Correlation analysis between LULC and stormwater quality showed the influence of different factors such as farming practices, geographical location, and amount of precipitation, vegetation loss, and anthropogenic activities in monitoring sites. This research found that GIS application was an efficient tool for monthly monitoring, validation and statistical analysis of LULC change in the study area.
Exponential fed-batch strategy for enhancing biosurfactant production by Bacillus subtilis
Authors: Amin G. A.
Published: July 2014

Surfactin produced by Bacillus subtilis BDCC-TUSA-3 from Maldex-15 was used as a growth-associated product in a conventional batch process. Maldex-15 is a cheap industrial by-product recovered during manufacturing of high fructose syrup from corn starch. Surfactin production was greatly improved in exponential fed-batch fermentation. Maldex-15 and other nutrients were exponentially fed into the culture based on the specific growth rate of the bacterium. In order to maximize surfactin yield and productivity, conversion of different quantities of Maldex-15 into surfactin was investigated in five different fermentation runs. In all runs, most of the Maldex-15 was consumed and converted into surfactin and cell biomass with appreciable efficiencies. The best results were obtained with the fermentation run supplied with 204 g Maldex-15. Up to 36.1 g l−1 of surfactin and cell biomass of 31.8 g l−1 were achieved in 12 h. Also, a marked substrate yield of 0.272 g g−1 and volumetric reactor productivity of 2.58 g 1−1 h−1 were obtained, confirming the establishment of a cost-effective commercial surfactin production.
Performance evaluation and spatial sludge distribution at facultative and maturation ponds treating wastewater from an international airport
Authors: Passos Ricardo Gomes , von Sperling Marcos , Ribeiro Thiago Bressani
Published: July 2014

This paper presents a performance evaluation of facultative and maturation ponds in series treating wastewater from a large and intensively used international airport in Brazil, based on 16 years of regular monitoring. The wastewater from the airport showed similar or slightly lower concentrations compared to typical domestic sewage for most of the quality parameters. The contribution of effluents with possible industrial features (aircraft toilets and hangar effluent) did not seem to have adversely affected the characteristics of the influent in terms of aptitude to biological treatment. Overall, the ponds operated under very underloaded conditions (mean loading rate of 44 kg biochemical oxygen demand/ha.d in the facultative pond) and presented a satisfactory quality in terms of effluent concentrations for most parameters. A bathymetric survey of the ponds was done manually by a low-cost measurer constructed specifically for this purpose. After 27 years of operation, only 25% and 18% of the volumes of the facultative and maturation ponds were occupied by sludge. Specific sludge accumulation rates were 0.0071 m³/passenger.year for the facultative pond and 0.00017 m³/passenger.year for the maturation pond.
Modelling the viability of heat recovery from combined sewers

Published: July 2014

Modelling of wastewater temperatures along a sewer pipe using energy balance equations and assuming steady-state conditions was achieved. Modelling error was calculated, by comparing the predicted temperature drop to measured ones in three combined sewers, and was found to have an overall root mean squared error of 0.37 K. Downstream measured wastewater temperature was plotted against modelled values; their line gradients were found to be within the range of 0.9995–1.0012. The ultimate aim of the modelling is to assess the viability of recovering heat from sewer pipes. This is done by evaluating an appropriate location for a heat exchanger within a sewer network that can recover heat without impacting negatively on the downstream wastewater treatment plant (WWTP). Long sewers may prove to be more viable for heat recovery, as heat lost can be reclaimed before wastewater reaching the WWTP.
Nitrogen behavior during sludge ozonation: a long-term observation by pilot experiments
Authors: Sui Pengzhe , Nishimura Fumitake , Tsuno Hiroshi
Published: July 2014

Sludge ozonation is a promising technology for dealing with the increasing challenge of excess sludge treatment and disposal. However, nitrogen behavior during sludge ozonation and subsequent biological removal remains unclear. To clarify the feasibility and stability of oxidizing organic nitrogen (released during sludge ozonation) in the bioreactor (but not during ozonation), and the best operational conditions for sludge ozonation, nitrogen behavior was investigated by a long-term observation. The results showed that when inlet ozone concentration increased from 30 to 80 mg O3/L, and ozonation time decreased from 29 to 11 h, less soluble organic nitrogen was oxidized to ammonia (from 66.1 to 18.7% of soluble total nitrogen). This can reduce the operational costs of sludge ozonation. Furthermore, it is feasible to convert organic nitrogen to nitrate by biological processes because full nitrification was restored in three weeks after shock loading of organic nitrogen owing to the change in ozonation conditions. After combining sludge ozonation with the anaerobic/oxic process, the mass balance for nitrogen showed that nitrogen in the excess sludge decreased with increasing sludge reduction rate. The decreased nitrogen in the excess sludge was mainly transformed to nitrogen gas by denitrification, whereas nitrogen in the effluent did not increase noticeably.

Published: July 2014

Some species of microalgae have high productivity and lipid content, which makes them good candidates for biodiesel production. Biomass separation and cell disruption are important steps in biodiesel production from microalgae. In this work, we explored the fundamentals of electroflotation by alternating current (EFAC) with non-consumable electrodes to simultaneously harvest microalgae and disrupt cells from mixed microalgae obtained from waste stabilization ponds. The harvesting efficiency was evaluated using chlorophyll-a and turbidity, which reached removals of 99% and 95%, respectively, during a batch time of 140 min. Cell disruption was evaluated using lipid extraction, and the best results were achieved with a batch time of 140 min, which resulted in a 14% yield. Therefore, EFAC was shown to be an attractive potential technology for simultaneous microalgal harvesting and cell disruption.

Published: July 2014

As alternative materials for heavy metal removal, this study investigated biosorbents to determine their suitability for permeable reactive barriers. The lead removal efficiencies of brown seaweed (Undaria pinnatifida) and reed (Phragmites australis) were determined under different conditions (batch and column system). The experimental results for these biomaterials fitted the Langmuir isotherm with high correlation values. It was verified that the influence of temperature on affinity was higher than that on adsorption capacity. While the lead removal efficiency of U. pinnatifida was higher than of P. australis in the batch experiments, lead removal efficiency decreased for both materials at approximately the same time in the column experiments. This indicates that the dominance of the chemical and physical adsorption mechanisms could result in differences in these systems.

Published: July 2014

Polishing ponds are natural systems used for the post-treatment of upflow anaerobic sludge blanket (UASB) effluents. They are designed as maturation ponds and their main goal is the removal of pathogens and nitrogen and an additional removal of residual organic matter from the UASB reactor. This study aimed to evaluate organic matter and suspended solids removal as well as sludge accumulation in two shallow polishing ponds in series treating sanitary effluent from a UASB reactor with a population equivalent of 200 inhabitants in Brazil, operating since 2002. For this evaluation, long-term monitoring of biochemical oxygen demand and total suspended solids and bathymetric surveys have been undertaken. The ponds showed an irregular distribution of total solids mass in the sludge layer of the two ponds, with mean accumulation values of 0.020 m3 person−1 year−1 and 0.004 m3 person−1 year−1 in Ponds 1 and 2, leading to around 40% and 8% of the liquid volume occupied by the sediments after 11 years of operation. The first pond showed better efficiency in relation to organic matter removal, although its contribution was limited, due to algal growth. No simple input–output mass balance of solids can be applied to the ponds due to algal growth in the liquid phase and sludge digestion in the sludge.
Coagulation pretreatment of highly concentrated acrylonitrile wastewater from petrochemical plants
Authors: Zheng Dongju , Qin Lin , Wang Tao , Ren Xiaojing , Zhang Zhongguo , Li Jiding
Published: July 2014

Acrylonitrile (AN) wastewater is a heavily polluted and a likely hazardous liquid that is generated during the production of AN. Several chemical methods for the pretreatment of AN wastewater are available in laboratory scale. However, the harsh reaction conditions and high operational cost make these methods undesirable. Until now, four-effect evaporation is the only pretreatment method used for AN wastewater in industry despite its huge energy consumption and high cost. It is difficult to find an energy-saving pretreatment technique from the perspective of industrial application. In this study, a safe and low-cost coagulation technique was developed for the pretreatment of AN wastewater. Three types of inorganic coagulant and three types of polymer coagulant were investigated for the coagulation treatment of highly concentrated AN wastewater from petrochemical plants. The effects of coagulant type, dosage, and coagulation conditions on the pretreatment efficiency of AN wastewater were investigated. The results show that a combination of inorganic and polymer coagulants is effective for the pretreatment of AN wastewater.
Improving nutrient fixation and dry matter content of an ammonium-rich anaerobic digestion effluent by struvite formation and clay adsorption
Authors: Estevez Maria M. , Linjordet Roar , Horn Svein J. , Morken John
Published: July 2014

The anaerobic digestion (AD) of organic wastes that contain nitrogen leads to its mineralization, yielding a digestate rich in ammonium (NH4+), an important fertilizing nutrient. The applicability of AD digestate as fertilizer can be improved by fixating the nutrients and increasing its dry matter content. Methods for the fixation and recovery of the digestate's NH4+ and possible also PO43− include struvite precipitation and adsorption in clay materials such as bentonite. These techniques were tested in batch experiments employing the liquid fraction of a digestate originating from the AD of a substrate mix containing lignocellulose, cattle manure and fish industrial waste. The concentration of NH4+-N in this digestate was 2,300 mg L−1. Struvite precipitation conditions at a molar ratio of 1.2:1:1 (Mg2+:NH4+:PO43−) and pH 9.5 were best in terms of simultaneous removal of NH4+-N (88%), PO43− (60%) and soluble chemical oxygen demand (44%). Bentonite adsorption gave comparably high removal levels for NH4+-N (82%) and PO43− (52%). Analysis of the precipitates' morphology and elemental composition confirmed their struvite and bentonite nature. Dry matter content was increased from 5.8% in the AD digestate to 27% and 22% in the struvite and bentonite sludges, respectively.
Organic matter and nitrogen removal at planted wetlands treating domestic septage with varying operational strategies
Authors: Jong Valerie Siaw Wee , Tang Fu Ee
Published: July 2014

A two-staged engineered wetland-based system was designed and constructed to treat raw domestic septage. Hydraulic loading rates (HLRs) of 8.75 and 17.5 cm/d were studied with four and eight daily dosings at the second stage of the system to investigate the influence of the regimes on septage treatment. Removal of organic matter (OM) was found to be HLR dependent, where the results indicated that the increase of HLR from 8.75 to 17.5 cm/d impaired the overall level of treatment in the wetland units. Effluent of wetland fed at HLR 17.5 cm/d presented significantly lower oxygen reduction potential and dissolved oxygen values than wetland fed at 8.75 cm/d, indicative of the occurrence of less aerobic and reductive conditions in the bed. The reoxygenation capability of the wetland units was found to be heavily affected by the dosing frequency especially under high hydraulic load (17.5 cm/d). NH3-N degradation was found to decrease with statistical importance when the wetland was flushed two times more frequently with smaller batches of influent. The number of hydraulic load fractionings did not seem to affect the level of treatments of OM and ammonia for both the wetlands fed under the lower HLR of 8.75 cm/d. Prediction of hydraulic limits and management of the feeding strategies are important in the vertical type of engineered wetlands to guarantee the treatment performance and minimize the chances of filter clogging.
Process Management Plans
Authors: Miksa Tomasz , Strodl Stephan , Rauber Andreas
Published: July 2014

In the era of research infrastructures and big data, sophisticated data management practices are becoming essential building blocks of successful science. Most practices follow a data-centric approach, which does not take into account the processes that created, analysed and presented the data. This fact limits the possibilities for reliable verification of results. Furthermore, it does not guarantee the reuse of research, which is one of the key aspects of credible data-driven science. For that reason, we propose the introduction of the new concept of Process Management Plans, which focus on the identification, description, sharing and preservation of the entire scientific processes. They enable verification and later reuse of result data and processes of scientific experiments. In this paper we describe the structure and explain the novelty of Process Management Plans by showing in what way they complement existing Data Management Plans. We also highlight key differences, major advantages, as well as references to tools and solutions that can facilitate the introduction of Process Management Plans.
DataShare: Empowering Researcher Data Curation

Published: July 2014

Researchers are increasingly being asked to ensure that all products of research activity â€“ not just traditional publications â€“ are preserved and made widely available for study and reuse as a precondition for publication or grant funding, or to conform to disciplinary best practices. In order to conform to these requirements, scholars need effective, easy-to-use tools and services for the long-term curation of their research data. The DataShare service, developed at the University of California, is being used by researchers to: (1) prepare for curation by reviewing best practice recommendations for the acquisition or creation of digital research data; (2) select datasets using intuitive file browsing and drag-and-drop interfaces; (3) describe their data for enhanced discoverability in terms of the DataCite metadata schema; (4) preserve their data by uploading to a public access collection in the UC3 Merritt curation repository; (5) cite their data in terms of persistent and globally-resolvable DOI identifiers; (6) expose their data through registration with well-known abstracting and indexing services and major internet search engines; (7) control the dissemination of their data through enforceable data use agreements; and (8) discover and retrieve datasets of interest through a faceted search and browse environment. Since the widespread adoption of effective data management practices is highly dependent on ease of use and integration into existing individual, institutional, and disciplinary workflows, the emphasis throughout the design and implementation of DataShare is to provide the highest level of curation service with the lowest possible technical barriers to entry by individual researchers. By enabling intuitive, self-service access to data curation functions, DataShare helps to contribute to more widespread adoption of good data curation practices that are critical to open scientific inquiry, discourse, and advancement.
Towards a Symbiotic Relationship Between Academic Libraries and Disciplinary Data Repositories: A Dryad and University of Michigan Case Study
Authors: Akers Katherine G. , Green Jennifer A.
Published: July 2014

In addition to encouraging the deposit of research data into institutional data repositories, academic librarians can further support research data sharing by facilitating the deposit of data into external disciplinary data repositories. In this paper, we focus on the University of Michigan Library and Dryad, a repository for scientific and medical data, as a case study to explore possible forms of partnership between academic libraries and disciplinary data repositories. We found that although few University of Michigan researchers have submitted data to Dryad, many have recently published articles in Dryad-integrated journals, suggesting significant opportunities for Dryad use on our campus. We suggest that academic libraries could promote the sharing and preservation of science and medical data by becoming Dryad members, purchasing vouchers to cover researchersâ€™ data submission costs, and hosting local curators who could directly work with campus researchers to improve the accuracy and completeness of data packages and thereby increase their potential for re-use. By enabling the use of both institutional and disciplinary data repositories, we argue that academic librarians can achieve greater success in capturing the vast amounts of data that presently fail to depart researchersâ€™ hands and making that data visible to relevant communities of interest.

This paper explores three stories, each occurring a year apart, illustrating an evolution toward a strategic vision for Library leadership in supporting research data management at the University of Sydney. The three stories describe activities undertaken throughout the Seeding the Commons project and beyond, as the establishment of ongoing roles and responsibilities transition the Library from project partner to strategic leader in the delivery of research data management support. Each story exposes key ingredients that characterise research data management support: researcher engagement; partnerships; and the complementary roles of policy and practice.
Committing to Data Quality Review
Authors: Peer Limor , Green Ann , Stephenson Elizabeth
Published: July 2014

Amid the pressure and enthusiasm for researchers to share data, a rapidly growing number of tools and services have emerged. What do we know about the quality of these data? Why does quality matter? And who should be responsible for data quality? We believe an essential measure of data quality is the ability to engage in informed reuse, which requires that data are independently understandable. In practice, this means that data must undergo quality review, a process whereby data and associated files are assessed and required actions are taken to ensure files are independently understandable for informed reuse. This paper explains what we mean by data quality review, what measures can be applied to it, and how it is practiced in three domain-specific archives. We explore a selection of other data repositories in the research data ecosystem, as well as the roles of researchers, academic libraries, and scholarly journals in regard to their application of data quality measures in practice. We end with thoughts about the need to commit to data quality and who might be able to take on those tasks.
Challenges of Public Health Nurses in Coordinating Relationships: Scale Development
Authors: Ishii Miyuki , Matsuda Nobuko
Published: July 2014

We developed a scale for measuring the challenges faced by public health nurses in coordinating relationships for supporting preschool children with autism spectrum disorder, and examined the scale's construct validity using a factorial structure model. Participants were 708 Japanese
public health nurses. The secondary structural model consisted of 6 factors with 25 items. Internal consistency and reliability were high and confirmatory factor analysis using structural equation modeling indicated that the fit criteria were statistically significant. Attributes of public
health nurses were significantly related to scale scores. These findings validate the efficacy of our scale to identify and assess the challenges of public health nurses in relationship coordination.

Published: July 2014

Youth violence is a significant public health issue in Thailand where most people who are injured are vocational college students. There is a need to identify methods whereby such violence can be prevented. We trialed a group program in a technical college in Thailand with 23 students
who received a modified version of aggression replacement training. We then compared their results with those of 24 students who did not receive any intervention or preintervention at 1 and 3 month followups. Although we found little evidence supporting the effectiveness of the intervention,
participants in the intervention group suggested in the followup in-depth interviews that they felt more able to avoid or ignore provocation, and that they thought more about the consequences of aggressive behavior than they did prior to the intervention.
The Influence of College Students' Coping Styles on Perceived Self-Efficacy in Managing Inferiority
Authors: Shi Changxiu , Zhao Xiaojun
Published: July 2014

We examined the influence of college students' coping styles on perceived self-efficacy, through the mediating effect of general self-efficacy, in managing inferiority. A sample of 206 college students completed a Coping Style Questionnaire, the Regulatory Emotional Self-Efficacy Scale
of Chinese college students, and a general self-efficacy scale. The results showed the following: (a) there were significant correlations among the problem solving, self-blame, and fantasy coping styles, and general self-efficacy and perceived self-efficacy in managing inferiority; (b) the
problem solving and self-blame coping styles indirectly predicted perceived self-efficacy in managing inferiority by general self-efficacy, and general self-efficacy played a partial mediating role between the problem solving and self-blame coping styles and perceived self-efficacy in managing
inferiority; and (c) gender played a moderating role between coping style and perceived self-efficacy in managing inferiority. The results are important for counseling to enhance regulatory emotional self-efficacy.
The Effects of Loneliness and Coping Style on Academic Adjustment Among College Freshmen

Published: July 2014

We explored the relationships among loneliness, coping style, and adjustment to college from high school. Participants were a sample of 276 college freshmen from a university in China. The measures we used were the Emotional and Social Loneliness Scale, the Coping Style Scale for College
Students, and the Academic Adjustment Scale for College Students. We found that loneliness had a direct negative effect on adjustment, and also negatively affected adjustment by activating a negative coping style and suppressing a positive coping style. Both forms of coping style played a
mediating role in the relationship between loneliness and adjustment to college. Our findings add to the extant literature on the relationships among loneliness, coping styles, and academic adjustment in China, and have implications for addressing Chinese freshmen's adjustment to college life
from a new perspective.

Background: The data for gender differences in colorectal cancer (CRC)
presentation and survival are conflicting, most likely reflecting the
National approach to CRC screening. Patients and Methods: Analysis was
performed on 431 patients presenting with CRC to a single tertiary
institution between 1989 and 2002, assessing gender differences in clinical
presentation and cancer-specific survival. Results: Males presented more
commonly with rectal bleeding, weakness/lethargy and occult blood positivity
with women more commonly presenting with constipation, abdominal pain and
anemia. Women presented with a more advanced AJCC stage (III or IV) than men
(P<0.0001) and with a higher Dukes? stage (P<0.001), with no gender
differences in histologic grade of CRC. The positive histologic nodal burden
was greater in women than in men (P <0.0001). There was no difference between
the sexes in stage for right-sided colonic tumors and a barely significant
trend in left-sided colonic and rectal tumors towards more advanced stage
presentation in females. The overall 5-year and 10-year survival rates were
higher in males when compared with females (91.8%vs.72.2% 5-year OS
respectively, P<0.0001 and 40.6% vs. 23.9% 10-year OS respectively,
P<0.0001). A worse survival was evident in women > 65 years, for all sites of
cancer and for all cancer stages exceeding Dukes? stage A. Discussion: There
are inherent sex differences in the clinical presentation, pathologic
features, primary site and survival in CRC. An improved understanding of
gender-related differences in CRC could influence the quality provision of
care in women, particularly regarding screening and the more regulated use of
adjuvant therapies with proven benefit.

OBJECTIVE: The aim of this study was to evaluate which factors are best
predictors of hearing improvement after tympanoplasty and to evaluate best
functional outcome in different forms of pathology in the tympanic cavity and
mastoid in chronic otitis media. METHODS: Prospective study included 120
patients who were operated for chronic suppurative otitis media and
cholesteatoma in the ENT Department University Clinic Center Banja Luka from
2006 to 2011. Multiple linear regression analysis was used to measure which
factors predict better hearing improvement. MAIN OUTCOME MEASURES: A model
that evaluates factors related to chronic otitis media: ossicular chain
integrity, tympanic tube function, tympanic membrane perforation, type of
surgery and condition of tympanic and mastoid walls was used to predict
postoperative hearing improvement. Hearing outcome was measured comparing
preoperative to postoperative pure-tone average (PTA) and postoperative
air-bone gap (ABG). RESULTS: Out of 120 operated patients, we performed
primary surgery in 106 and revision surgery in 9 cases due to recurrent
cholesteatoma. We observed high correlation and statistically significant
contribution of ossicular chain pathology (b=-0.310, t=-3.01, p<0.05), and
mastoid bone erosion or defects (b=2.05, t=2.05 , p<0.05), on the variance of
PTA. The same variables were highly correlated with ABG closure: ossicular
chain pathology (b=-0.230, t=-2.14, p<0.05), and mastoid bone erosion or
defects (b= 2.05, t=2.08 , P<0.05). Variance of preoperative to postoperative
PTA difference explained by the model as a whole was 24,7%, F(8,119)=4.54 ,
p<0.01. Variance of preoperative to postoperative ABG difference explained by
the model as a whole was 18,3% F(8,119)=3.1, p<0.01. The predictive model in
this study included 8 variables related to middle ear pathology proved to be
superior to analyzing each variable separately. CONCLUSION: A model that
evaluates factors related to chronic otitis media: ossicular chain integrity,
tympanic tube function, tympanic membrane perforation, type of surgery and
condition of tympanic and mastoid walls has significant predictive value for
hearing assessment in tympanoplasty.

Introduction. Intracranial aneurysms are very rare in the pediatric
population . Very rarely they are accompanied by subarachnoid hemorrhage
(SAH). As in the adults they are most often discovered after their rupture.
Case report. We report the case of a child 14 months old at the time of
rupture of the aneurysm , which led to intraventricular hemorrhage and
accompanied by left side body weakness. After diagnosis - digital subtraction
angiography (DSA) aneurysm on the posterior chorioid artery was verified.
Consultatory there was no decision for surgical treatment. The child is now 6
years old, there is a discrete left side pyramidal deficit , control DSA -
finding stationary. Conclusion: Despite the development of modern diagnosis
of intracranial aneurysms their treatment is still a big challenge. Child?s
brain has great recovery potential, which encourages aggressive therapy for
these disorders and provide good results. In younger patients with ruptured
aneurysms and vascular anomalies associated with neurological deficit, where
surgical treatment or endovascular procedures associated with the high risk
of complications, conservative treatment is indicated.

Multidetector computed tomographic angiography (MDCTA) is a non-invasive,
highly sophisticated and readily available diagnostic method nowadays gained
primacy in the algorithm of the blood vessels of the brain. MDCTA showed the
highest sensitivity and specificity for early detection of ruptured
intracranial aneurysms. Saccular aneurysm geometry (shape and size), anatomic
localization, and patient-dependent factors individually and together
determine the risk of rupture of the aneurysm. Unruptured aneurysms in
anterior communicating artery showed twice the possibility of rupture than
other intracranial aneurysms. Clinical history ACoA aneurysms after rupture
is particularly difficult. This justifies the efforts to determine the real
risk of these aneurysms when SAH was not found on the native scan
endocranium. It is here that the diagnostic value and usefulness of MDCTA
examination increases significantly and its true dimension.

Introduction: Surgery of tumors localized in the motor cortex is challenging
because of the accompanying risk of de novo occurrence of motor deficits.
Materials and methods: We report a series of 34 patients with slow-growing
brain tumors localized in and around the motor areas of the brain, which were
treated at the Institute of Neurosurgery, Clinical Center in Belgrade in the
period 2008-2012. Result. The average distance of the central sulcus in
relation to the coronary suture verified ES is 18.38 mm ? 9,564 mm, the
strength of the current required to obtain motor responses was 9.26?1.286 mA.
If the distance from the coronary suture is higher, the current intensity
required to cause the motor response is lower (p<0,01). The smaller amount of
current is needed to identify the motor areas of tumors where the degree of
surgical resection was subtotal to the level of reduction compared to radical
surgery (p<0,05). Conclusion. Direct electrostimulation of the cortex is a
reliable method for identification of motor areas of the brain, and it is
necessary for additional prevention - iatrogenic neurological deficits.

The occurrence of inflammatory bowel disease in patients with glycogen
storage disease Ib is rare (GSDIb).We present the case of a young woman with
the diagnosis of GSD-Ib Crohn-like colitis developed at age 27. She was under
regular medical control because of severe malnutrition, secondary amenorrhea,
leukopenia, neutropenia, hyperlipidaemia, dysfunctions of phagocytosis, and a
subtotal stenosis of the ascending colon. Several months after diagnosing
Crohn-like colitis, symptoms and signs of ileus developed, and she was
admitted in the Emergency room department. Baloon dilatation with local
corticosteroid injection was used for treatment. Clinical status of the
patient markedly improved after this intervention. As far as we know, no
similar cases with this kind of treatment are published.
