Benefits of owner mandated CM/GC contract amendment templates
Authors: Feuer Matt , Glick Scott , Clevenger Caroline M 
Published: June 2015

Purpose
– The purpose of this paper is to explore how implementing a standardized/owner-mandated template for Construction Manager/General Contractor (CM/GC) contract amendments can minimize errors. The focus is on public owners who manage multiple CM/GC projects at any one time.

Design/methodology/approach
– A case study format was used to compare contract amendments errors using a baseline project, transition project and best practices project. Six metrics were identified, including factual recital errors, summary formatting errors, schedule of values errors, construction services fee errors, allowance schedule errors and data consistency errors.

Findings
– The baseline and transition projects both had an average of seven errors per amendment, while the best practices project produced zero errors. The amendment template creation process helped design out common errors. The use of the template can be contract-mandated, while transition projects require owner commitment.

Research limitations/implications
– Future research should focus on completed projects’ closeout data that have been consolidated since the transition project was in its final stage and the best practices project was relatively early in the construction process.

Practical implications
– The findings of this research indicate that by implementing a mature owner-mandated CM/GC contract amendment template, owners can greatly reduce errors that arise during the amendment process. It should be noted, however, that challenges will most likely occur during the implementation phase.

Originality/value
– No similar studies were found and the results of the research informs Facilities Management departments that they can significantly reduce errors by utilizing a mature, owner-mandated template for CM/GC contract amendments.

Authors: Dehghani Razieh , Ramsin Raman 
Published: June 2015

Purpose
– This paper aims to provide a criteria-based evaluation framework for assessing knowledge management system (KMS) development methodologies.

Design/methodology/approach
– The evaluation criteria have been elicited based on the features expected from a successful KMS. Furthermore, a number of prominent KMS development methodologies have been scrutinized based on the proposed evaluation framework.

Findings
– It was demonstrated that the proposed evaluation framework is detailed and comprehensive enough to reveal the strengths and weaknesses of KMS development methodologies. It was also revealed that even though the evaluated methodologies possess certain strong features, they suffer from several shortcomings that need to be addressed.

Research limitations/implications
– The evaluation framework has not been applied to all existing KMS development methodologies; however, the evaluation does cover the most comprehensive methodologies which exist in the research context.

Practical implications
– The results of this research can be used for the following purposes: organizational goal-based selection of KMS development methodologies, evolution of existing KMS development methodologies and engineering of tailored-to-fit KMS development methodologies.

Originality/value
– The proposed evaluation framework provides a comprehensive and detailed set of criteria for assessing general, area-specific and context-specific features of KMS development methodologies. KMS developers can select the methodology which best fits their requirements based on the evaluation results. Furthermore, method engineers can extend existing methodologies or engineer new ones so as to satisfy the specific requirements of the project at hand.
Knowledge sharing in open source software communities: motivations and management
Authors: Iskoujina Zilia , Roberts Joanne 
Published: June 2015

Purpose– This paper aims to add to the understanding of knowledge sharing in online communities through an investigation of the relationship between individual participant’s motivations and management in open source software (OSS) communities. Drawing on a review of literature concerning knowledge sharing in organisations, the factors that motivate participants to share their knowledge in OSS communities, and the management of such communities, it is hypothesised that the quality of management influences the extent to which the motivations of members actually result in knowledge sharing.Design/methodology/approach– To test the hypothesis, quantitative data were collected through an online questionnaire survey of OSS web developers with the aim of gathering respondents’ opinions concerning knowledge sharing, motivations to share knowledge and satisfaction with the management of OSS projects. Factor analysis, descriptive analysis, correlation analysis and regression analysis were used to explore the survey data.Findings– The analysis of the data reveals that the individual participant’s satisfaction with the management of an OSS project is an important factor influencing the extent of their personal contribution to a community.Originality/value– Little attention has been devoted to understanding the impact of management in OSS communities. Focused on OSS developers specialising in web development, the findings of this paper offer an important original contribution to understanding the connections between individual members’ satisfaction with management and their motivations to contribute to an OSS project. The findings reveal that motivations to share knowledge in online communities are influenced by the quality of management. Consequently, the findings suggest that appropriate management can enhance knowledge sharing in OSS projects and online communities, and organisations more generally.
Does organizational forgetting matter? Organizational survival for life coaching companies
Authors: Aydin Erhan , Gormus Alparslan Sahin 
Published: June 2015

Purpose– The purposes of this paper are to determine the role of organizational forgetting in different type of coaching companies and to determine organizational survival based on both knowledge structure of coaching companies and organizational forgetting with core features of organizations.Design/methodology/approach– Within the context of this research, two worldwide and well-known coaching companies were examined as case study, and analyses of case studies which included company background and testimonial analysis was used as inputs for the semi-structured interviews of 12 PhD students in the UK who took seminars and training from the coaching companies. Based on the interviews, the authors concluded the research as describing knowledge structure, core features and organizational forgetting type. Thus, organizational survival based on organizational forgetting could be interpreted.Findings– Based on the case studies and interview results, there were two findings. First, it was indicated that the type of organization (knowledge structure) had a different type of organizational forgetting. Second, core features of organizations based on the interviews and types of organizational forgetting were linked to each other. According to these results, organizational survival for coaching companies was discussed.Research limitations/implications– This study also has some limitations. First, this paper just focuses on coaching organizations to find new perspective for the organizational forgetting literature. Second, because of the scope of this research, interviewees are limited to individuals who have knowledge or take any seminars related to field of coaching. Other sectors also must be considered to attain detailed knowledge related to organizational forgetting because case-specific studies will bring new dimensions to the literature of organizational forgetting.Originality/value– First, this study makes a research contribution to the field of organizational forgetting because studies related to organizational forgetting mostly consist of conceptual papers, and, second, we have introduced two new perspective to the concept of organizational forgetting through this research paper.
Development of a New Paenibacillin‐Producing Strain and Testing its Usability in Improving Food Safety
Authors: Gerst Michelle M. , Huang En , Zhang Liwen , Yousef Ahmed E. 
Published: June 2015

AbstractA new bacterial strain that produces a bacteriocin (paenibacillin) without polymyxin was developed from Paenibacillus polymyxa that co‐produces the 2 antimicrobial agents. Gamma radiation was used successfully to develop the new strain, P. polymyxa OSY‐HG. Subsequently, we explored the feasibility of using food or food ingredients as growth media for the new strain. Milk supported the growth of P. polymyxa OSY‐HG which produced up to 32 mg paenibacillin/L milk without polymyxin. Fermentation crude extract was applied in a model food (Vienna sausage) to control Listeria innocua, a Listeria monocytogenes surrogate. The treatment increased Listeria lag time by 2 d at 7 °C and at least 6 h at 37 °C. In conclusion, a new paenibacillin‐producing P. polymyxa strain has been developed for potential industrial use. Using the new strain in applications that enhance food safety is feasible.
Increased IL‐37 in Atherosclerotic Disease could be Suppressed by Atorvastatin Therapy
Authors: Shaoyuan C. , Ming D. , Yulang H. , Hongcheng F. 
Published: June 2015

AbstractRecently, the evidence showed that interleukin‐37 (IL‐37) was expressed in the foam‐like cells of atherosclerotic coronary and carotid artery plaques in IL‐37‐transgenic mice, suggesting that interleukin‐37 is involved in atherosclerosis‐related diseases. The purpose of this study was to determine the change of IL‐37 in atherosclerotic plaque, the effect of atorvastatin on IL‐37 and the association between IL‐37 and Smad3 in atherosclerotic disease. Rabbits were subjected to atherosclerosis by the immunologic injury composite with balloon injury (BI). Some rabbits received atorvastatin treatment from 6 weeks to 12 weeks. Serum levels of IL‐37 were assessed at baseline, 6 weeks and 12 weeks in normal, atherosclerotic and atorvastatin groups. Protein and RNA levels of IL‐37 atherosclerotic plaque from abdominal aorta were processed at 12 weeks. Abdominal aorta including atherosclerotic plaque was immunostained with IL‐37 and Smad3. Serum IL‐37 significantly increased in atherosclerotic disease, and this increase could be reduced by the atorvastatin treatment. IL‐37 and Smad3 were accumulated in the macrophage‐derived foam cells in the plaque and significantly increased in protein and RNA levels. Atorvastatin treatment could significantly suppress the increase of both IL‐37 and Smad3. Plasma level of IL‐37 and the IL‐37 expression of the plaque were significantly increased in atherosclerotic disease. This increase could be suppressed by the atorvastatin treatment. In addition, Smad3 might be required for IL‐37 activity during the atherosclerotic physiologic process.

Published: June 2015

ObjectiveTo evaluate cost-effectiveness of second HIV test in pregnancy.BackgroundCurrent strategy of single HIV test during pregnancy in India can miss new HIV infections acquired after the first test or those HIV infections that were missed in the first test due to a false-negative HIV test.MethodsBetween August 2011 and April 2013, 9097 pregnant HIV uninfected women were offered a second HIV test near term (34 weeks or beyond) or within 4 weeks of postpartum period. A decision analysis model was used to evaluate cost-effectiveness of a second HIV test in pregnant women near term.Primary and secondary outcomeOur key outcome measures include programme cost with addition of second HIV test in pregnant women and quality-adjusted life years (QALYs) gained.ResultsWe detected 4 new HIV infections in the second test. Thus HIV incidence among pregnant women was 0.12 (95% 0.032 to 0.297) per 100 person women years (PWY). Current strategy of a single HIV test is 8.2 times costlier for less QALYs gained as compared to proposed repeat HIV testing of pregnant women who test negative during the first test.ConclusionsOur results warrant consideration at the national level for including a second HIV test of all pregnant women in the national programme. However prior to allocation of resources for a second HIV test in pregnancy, appropriate strategies will have to be planned for improving compliance for prevention of mother-to-child transmission of HIV and reducing loss-to-follow-up of those women detected with HIV.Trial registration numberCTRI/2013/12/004183.

Published: June 2015

IntroductionChronic diseases and falls substantially contribute to morbidity/mortality among seniors, causing this population to frequently seek emergency medical care. Research suggests the paramedic role can be successfully expanded to include community-based health promotion and prevention. This study implements a community paramedicine programme targeting seniors in subsidised housing, a high-risk population and frequent users of emergency medical services (EMS). The aims are to reduce EMS calls, improve health outcomes and healthcare utilisation.Methods/analysisThis is a pragmatic clustered randomised control trial in four communities across Ontario, Canada. Within each, four to eight seniors’ apartment buildings will be paired and within each pair one building will be randomly assigned to receive the Community Health Assessment Programme through EMS (CHAP-EMS) intervention, while the other building receives no intervention. During the 1-year intervention, paramedics will run weekly sessions in a common area of the building, assessing risk factors for cardiovascular disease, diabetes and falls; providing health education and referrals to community programmes; and communicating results to the participant's primary physician. The primary outcomes are rate of emergency calls per 100 residents, change in blood pressure and change in Canadian Diabetes Risk (CANRISK) score, as collected by the local EMS and study databases. The secondary outcomes are change in health behaviours, measured using a preintervention and postintervention survey and healthcare utilisation, available through administrative databases. Analysis will mainly consist of descriptive statistics and generalised estimating equations, including subgroup cluster analysis.Ethics/disseminationThis study is approved by the Hamilton Integrated Research Ethics Board and will follow the Tri-Council Policy Statement. Findings will be disseminated through reports to local stakeholders, publication in peer-reviewed journals and conference presentations.Trial registration numberNCT02152891.
CacheAudit

Published: June 2015

We present CacheAudit, a versatile framework for the automatic, static analysis of cache side channels. CacheAudit takes as input a program binary and a cache configuration and derives formal, quantitative security guarantees for a comprehensive set of side-channel adversaries, namely, those based on observing cache states, traces of hits and misses, and execution times. Our technical contributions include novel abstractions to efficiently compute precise overapproximations of the possible side-channel observations for each of these adversaries. These approximations then yield upper bounds on the amount of information that is revealed.
In case studies, we apply CacheAudit to binary executables of algorithms for sorting and encryption, including the AES implementation from the PolarSSL library, and the reference implementations of the finalists of the eSTREAM stream cipher competition. The results we obtain exhibit the influence of cache size, line size, associativity, replacement policy, and coding style on the security of the executables and include the first formal proofs of security for implementations with countermeasures such as preloading and data-independent memory access patterns.
Detection of Political Manipulation in Online Communities through Measures of Effort and Collaboration
Authors: Lee Sihyung 
Published: June 2015

Online social media allow users to interact with one another by sharing opinions, and these opinions have a critical impact on the way readers think and behave. Accordingly, an increasing number of <i>manipulators</i> deliberately spread messages to influence the public, often in an organized manner. In particular, political manipulation—manipulation of opponents to win political advantage—can result in serious consequences: antigovernment riots can break out, leading to candidates’ defeat in an election. A few approaches have been proposed to detect such manipulation based on the level of social interaction (i.e., manipulators actively post opinions but infrequently befriend and reply to other users). However, several studies have shown that the interactions can be forged at a low cost and thus may not be effective measures of manipulation.
To go one step further, we collect a dataset for real, large-scale political manipulation, which consists of opinions found on Internet forums. These opinions are divided into manipulators and nonmanipulators. Using this collection, we demonstrate that manipulators inevitably work hard, in teams, to quickly influence a large audience. With this in mind, it could be said that a high level of collaborative efforts strongly indicates manipulation. For example, a group of manipulators may jointly post numerous opinions with a consistent theme and selectively recommend the same, well-organized opinion to promote its rank. We show that the effort measures, when combined with a supervised learning algorithm, successfully identify greater than 95% of the manipulators. We believe that the proposed method will help system administrators to accurately detect manipulators in disguise, significantly decreasing the intensity of manipulation.

Capítulo 3 da obra Um mito amazônico e sua história, de Peter Gow. Neste capítulo, Peter Gow inicia o esforço, delineado na Introdução de Um Mito Amazônico e sua História e perseguido ao longo do livro, de unir as tradições intelectuais de Malinowski e Lévi-Strauss, com vistas a uma melhor compreensão dos modos específicos de transformação da mitologia Piro (Yine), em especial da maneira como estes se transformam ao longo do ciclo de vida do narrador. Partindo dessa problemática, Gow apresenta o conceito etnográfico de mitopoiesis, uma das principais contribuições da obra no campo da etnologia ameríndia.Tradutor: Henrique PougyRevisão Técnica: Prof. Dr. Renato SztutmanReferência: GOW, Peter.
