CCA2 secure public‐key encryption scheme tolerating continual leakage attacks
Authors: Zhou YanWei , Yang Bo , Zhang Wenzheng , Mu Yi 
Published: October 2016

AbstractFor a public‐key encryption scheme to be applied in practical applications, it should withstand various leakage attacks (e.g., side‐channel attacks and cold‐boot attacks). To this end, we present a way of construct the more practical CCA2 secure public‐key encryption scheme tolerating leakage attacks, and the scheme's security is based on the hardness of classical decisional Diffie–Hellman assumption and the target collision resistant of one‐way hash function. Additionally, our proposal enjoys better performance, for example, all of elements of ciphertext will be random from the adversary's view, and any probabilistic polynomial‐time adversary cannot obtain leakage on the secret key from the ciphertext, and so on. In the bounded‐leakage setting, for any leakage parameter λ⩽logq − ω(logk)(q is the prime order of the underlying group, and k denotes the security parameter.), our proposal is secure against leakage‐resilient chosen‐ciphertext attacks, where λ is independent of the plaintext space, and has the constant size. However, in the real world, an adversary can continuously learn information on the secret key through a variety of leakage attacks and can trivially break the security of public‐key encryption scheme under the continual leakage attacks. Thus, we will improve our method to resist the continual leakage attacks. Similarly, for any round leakage parameter λC⩽logq − ω(logk), we can prove the security of the improvement scheme based on the hardness of decisional Diffie–Hellman assuming and the target collision resistant of one‐way hash function. With this important performance, our proposal may have some significant value in the practical applications, such as our proposal can provide the leakage‐resilient security for outsourcing data in the cloud computing environment.

CSP adoption: current status and future prospects
Authors: Ying Ming , Li Shu Qin 
Published: October 2016

AbstractContent security policy (CSP) is a security mechanism that can be used to mitigate cross‐site scripting (also known as XSS) and other related attacks. Although CSP is a promising mechanism to prevent XSS attack, it is not widely used. In this paper, we built a Java‐based web crawler to examine the current state of hypertext transfer protocol security headers and the adoption rate of CSP. The results show that usage for hypertext transfer protocol security headers is increasing. As for CSP, seven websites use CSP among the top 100 popular sites (8%) both in January and June 2015; 716 (0.066%) and 1241 (0.133%) websites enable CSP in January and June 2015, respectively (73% increase). A detailed analysis of the CSP settings that websites used is also performed. This analysis shows that many websites with CSP do not have the correct policies to prevent XSS. Finally, challenges for adopting CSP and methods to increase the adoption rate are discussed. Copyright © 2016 John Wiley & Sons, Ltd.
Associations among stress, gender, sources of social support, and health in emerging adults
Authors: Lee Chih‐Yuan Steven , Dik Bryan J. 
Published: October 2016

AbstractThis study aimed to examine how sources of social support intersect with stress and health by testing two theoretical models. Three relationship‐specific sources of social support (family, friends, and romantic partners) and two health indicators (self‐rated physical health and depressive symptoms) were investigated. The sample consisted of 636 emerging adults attending college (age range: 18–25). Results suggest that only support from family was a stress‐buffer, in that it buffered the adverse association between stress and depressive symptoms. Holding stress constant, only support from family was related to self‐rated physical health and only support from friends or romantic partners was associated with depressive symptoms. There were no gender differences in the mean levels of self‐rated physical health and depressive symptoms. However, gender moderations were found, in that the positive relationship between friends support and physical health was observed only in women, that the association between friends support and depressive symptoms was greater in men than in women, and that family support buffered the negative relationship between stress and physical health only in men. Findings of this study suggest that the associations among stress, social support, and health vary by the sources of support, the health outcome, and gender.
Will firms go green if it pays? The impact of disruption, cost, and external factors on the adoption of environmental initiatives
Authors: Dowell Glen W. S. , Muthulingam Suresh 
Published: October 2016

Research summary: Research on the link between financial and environmental performance implicitly assumes that firms will pursue profitable environmental actions. Yet, clearly, factors beyond profitability influence firms' environmental choices. We treat these choices as organizational change decisions and hypothesize that adoption of environmental initiatives is influenced by a combination of profit, level of disruption caused, and external influences. We test our hypotheses by examining firms' choices regarding implementation of energy‐savings initiatives. We find that degree of disruption, number of prior local adopters, and strength of environmental norms affect the adoption decisions. In addition, the effect of disruption is amplified by the implementation costs, but is mitigated by the number of prior local adopters.Managerial summary: Often, in trying to improve firms' environmental performance, academics and stakeholders have focused on actions that simultaneously improve environmental and financial performance. This assumes that firms will undertake projects that offer such dual benefits. We consider what might prevent firms from pursuing such ‘win‐win’ initiatives. We focus on how the degree of disruption of an energy‐saving initiative affects its probability of adoption. We find that firms are significantly more likely to adopt moderately profitable, but easy initiatives than more profitable but disruptive ones. We also examine internal and external factors that moderate the effect of disruption. Our findings suggest that in order to incentivize firms to improve environmental performance, it might be more beneficial make these activities less disruptive than to make them more profitable.

JAMES: An object‐oriented Java framework for discrete optimization using local search metaheuristics
Authors: De Beukelaer Herman , Davenport Guy F. , De Meyer Geert , Fack Veerle 
Published: October 2016

SummaryThis paper describes the Java Metaheuristics Search framework (JAMES, v1.1): an object‐oriented Java framework for discrete optimization using local search algorithms that exploits the generality of such metaheuristics by clearly separating search implementation and application from problem specification. A wide range of generic local searches are provided, including (stochastic) hill climbing, tabu search, variable neighbourhood search and parallel tempering. These can be applied to any user‐defined problem by plugging in a custom neighbourhood for the corresponding solution type. Using an automated analysis workflow, the performance of different search algorithms can be compared in order to select an appropriate optimization strategy. Implementations of specific components are included for subset selection, such as a predefined solution type, generic problem definition and several subset neighbourhoods used to modify the set of selected items. Additional components for other types of problems (e.g. permutation problems) are provided through an extensions module which also includes the analysis workflow. In comparison with existing Java metaheuristics frameworks that mainly focus on population‐based algorithms, JAMES has a much lower memory footprint and promotes efficient application of local searches by taking full advantage of move‐based evaluation. Releases of JAMES are deployed to the Maven Central Repository so that the framework can easily be included as a dependency in other Java applications. The project is fully open source and hosted on GitHub. More information can be found at http://www.jamesframework.org. Copyright © 2016 John Wiley & Sons, Ltd.
Serendipitous science engagement: A family self‐ethnography
Authors: Vedder‐Weiss Dana 
Published: October 2016

AbstractWhile opportunities for spontaneous, undesigned, serendipitous science engagement (SSE) are abundant and evidence regarding its affordances is accumulating, little is known about its nature. In this paper, I present a model defining and identifying SSE, which consists of a personal and a contextual continuum. To explore the nature of family SSE, I analyzed a 66‐minute case, obtained through self‐ethnography, of three children and a mother engaging with bugs they discovered in their backyard. Employing the “language games” approach, the analysis elucidates how the absence of designated goals enabled legitimate multiple language‐games over relatively long periods of time, with one game supporting the other. It also reveals delayed uptake, in which children appear to ignore scientific practice or content, while they are actually picking up ideas that they later use to engage with science. Examining processes of guided participation reveals that it entailed authentic modeling and gradual participation in the sense‐making game, without abandoning other games. I discuss implications for science learning and for learning theory more broadly, including parents’ role in SSE, issues of time for and in SSE, and guided participation in academic activities lacking designated goals. © 2016 Wiley Periodicals, Inc.

Published: October 2016

AbstractBackgroundThe aim of this systematic review was to update previous PROSPECT (http://www.postoppain.org) review recommendations for the management of pain after excisional haemorrhoidectomy.MethodsRandomized studies and reviews published in the English language from July 2006 (end date of last review) to March 2016, assessing analgesic, anaesthetic, and operative interventions pertaining to excisional haemorrhoidectomy in adults, and reporting pain scores, were retrieved from the EMBASE and MEDLINE databases.ResultsAn additional 464 studies were identified of which 74 met the inclusion criteria. There were 48 randomized controlled trials and 26 reviews. Quantitative analyses were not performed, as there were limited numbers of trials with a sufficiently homogeneous design.ConclusionPudendal nerve block, with or without general anaesthesia, is recommended for all patients undergoing haemorrhoidal surgery. Either closed haemorrhoidectomy, or open haemorrhoidectomy with electrocoagulation of the pedicle is recommended as the primary procedure. Combinations of analgesics (paracetamol, non‐steroidal anti‐inflammatory drugs, and opioids), topical lignocaine and glyceryl trinitrate, laxatives, and oral metronidazole are recommended post‐operatively. The recommendations are largely based on single intervention, not multimodal intervention, studies.

Published: October 2016

AbstractBackgroundAggressive hepatectomy is effective in treating intrahepatic stones and may minimize the deleterious consequences of subsequent cholangiocarcinoma (S‐CCA). The risk factors of S‐CCA after different methods of hepatectomy may vary with the resection scope of stone‐affected segments.MethodsWe reviewed the records of 981 patients of primary intrahepatic stones with elective hepatectomy from January 2000 to December 2010. The clinical characteristics of patients in the S‐CCA group (n = 55) and the control group (n = 926) were compared. The uniformity between extent of liver resection (ELR) with stone‐affected segments (SAS) was segmented into 2 varieties: ELR = SAS with ELR < SAS according to the different hepatic resection scopes. Cox regression model with forward selection was used to identify the risk factors of S‐CCA.ResultsIn the univariate analysis, significant differences were observed between the S‐CCA and control groups concerning stone location (unilateral 43.6 and 65.2 %, bilateral 56.4 and 34.8 %), residual stones (32.7 and 11.6 %), hepaticojejunostomy (43.6 and 30.9 %), and uniformity between ELR with SAS (ELR = SAS 20.0 and 42.6 %, ELR < SAS 80.0 and 57.4 %). Residual stones [hazard ratio (HR) 2.101, P = 0.016], hepaticojejunostomy (HR 1.837, P = 0.026) and uniformity between ELR and SAS (HR 2.442, P = 0.013) were independent prognostic factors for S‐CCA by a Cox regression analysis with forward selection. In the subsection of ELR = SAS group, the 5‐ and 10‐year postoperative tumor occurrence rates of unilateral and bilateral stones group were 0.9 versus 1.9 % and 3.0 versus 4.1 %, respectively (P = 0.663, log‐rank). In the other subsection of ELR < SAS group, the 5‐ and 10‐year postoperative tumor occurrence rates of unilateral and bilateral stones group were 3.4 versus 3.9 % and 6.8 versus 13.2 %, respectively (P = 0.047, log‐rank), and the 5‐ and 10‐year postoperative tumor occurrence rates of residual stones and non‐residual stones group were 5.8 versus 3.0 % and 16.0 versus 7.9 %, respectively (P = 0.015, log‐rank).ConclusionsPatients who underwent aggressive hepatectomy and had ELR = SAS had better outcomes than those with ELR < SAS. In the patients with ELR = SAS, the S‐CCA rates of unilateral and bilateral stones were low and comparable. However, patients with ELR < SAS and bilateral intrahepatic or residual stones should be monitored more carefully for high‐risk factors of S‐CCA.

Published: October 2016

AbstractThis article provides a current overview on clinical anatomy, pathophysiology, workup and surgical management of anorectal abscesses. Based on the three‐dimensional nature of anorectal abscesses, a novel treatment‐based classification is proposed. It examines the basis of a philosophic shift from simple drainage to concomitant definitive treatment of abscesses and their underlying primary fistulous trajectories. Complications are discussed specifically in this context.

Published: October 2016

AbstractBackgroundShared decision‐making is increasingly advocated in many countries. The aims of this study were to investigate whether patients receiving breast‐conserving surgery at Skåne University Hospital Malmö, Sweden, perceived an offered possibility to join in the decision‐making process regarding the surgical method; to identify potential determinants for not having perceived such an offer; and to study how this perception of being offered an opportunity to take part in the decision‐making process affected satisfaction with the aesthetic outcome.MethodsWomen offered breast‐conserving surgery were consecutively recruited over a period of 4 years. In all, 324 women completed a study‐specific questionnaire.ResultsA majority of the women (53 %) perceived that they had not, or had only partly, been offered a possibility to take part in the decision‐making process. Patients who reported that they had received enough preoperative information regarding the expected aesthetic result were more likely to have perceived such an offer (odds ratio (OR) 5.44; confidence interval (CI) 2.83–10.43). Women who had perceived an opportunity to be involved were more satisfied with the aesthetic result (OR 2.71; CI 1.18–6.25) and more likely to have had their expectations met regarding the aesthetic result (OR 5.91; CI 2.01–17.38).ConclusionWhen deciding on a suitable surgical approach for women with early breast cancer, physicians could try to more clearly communicate to the women that they can choose whether or not to participate in the decision‐making regarding surgical technique. This might improve satisfaction. An important part of patient involvement is sufficient preoperative information.
Patients with Amyotrophic Lateral Sclerosis Have High Interest in and Limited Access to Genetic Testing

Published: October 2016

AbstractAlthough genetic testing for amyotrophic lateral sclerosis (ALS) is widely available, it is unknown what proportion of patients with ALS have access to genetic counseling and testing, and patient attitudes towards ALS genetic testing have not been studied. We conducted a national survey of ALS patients enrolled in the Agency for Toxic Substances and Disease Registry, which consisted of multiple choice questions and two 12 item Likert scale series assessing respondents’ experience with and attitude toward genetic testing. The survey had an 8 % response rate, with 449 completed responses. Genetic testing was offered to 33.4 % and completed by 67.1 % of those offered. A minority of respondents (12.5 %) saw a genetic counselor, and were much more likely to be offered genetic testing (p = 0.0001). Respondents with a family history of ALS (8.4 %) were more likely to be offered testing (p = 0.0001) and complete testing (p = 0.05). Respondents with a family history of ALS were more likely to report a favorable attitude towards genetic testing (p = 0.0003), as were respondents who saw a genetic counselor (p = 0.02). The majority of respondents (82.7 %) felt that genetic testing should be offered to all patients with ALS. Our results indicate that ALS patients may have limited access to genetic testing, but perceive benefit from this service. Development of practice guidelines for genetic testing in ALS, to include the routine offer of genetic counseling, may result in broader and more consistent access to these services.
Science: the slow march of accumulating evidence

Published: October 2016

Recent crises over the credibility of research in psychology and the biomedical sciences have highlighted the need for researchers to view and treat replication research as essential to the accumulation of knowledge. In this article, the authors make the case for the utility of replication in medical education research. Specifically, the authors contend that because research in medical education often adopts theories from other disciplines, replication is necessary to gauge the applicability of those theories to the specific medical education context. This article introduces readers to the two major types of replication – direct and conceptual – and provides a primer on conceptual replication. In particular, the article presents key elements of conceptual replication and considers how it can be used to strengthen approaches to knowledge generation, theory testing, and theory development in medical education research.
Designing an efficient humanitarian supply network

Published: October 2016

AbstractIncreasingly, humanitarian organizations have opened regional warehouses and pre‐positioned resources locally. Choosing appropriate locations is not easy and frequently based on opportunities rather than rational decisions. Dedicated decision‐support systems could help humanitarian practitioners design their supply networks. Academic literature suggests the use of commercial sector models but rarely considers the constraints and specific context of humanitarian operations, such as obtaining accurate data, high uncertainties, limited budgets and increasing pressure on cost efficiency. We propose a tooled methodology to properly support humanitarian decision makers in the design of their supply chains. Our contribution is based on the definition of aggregate scenarios to reliably forecast demand using past disaster data and future trends. Demand for relief items based on these scenarios is then fed to a mixed‐integer linear programming model in order to improve current supply networks. The specifications of this model have been defined in close collaboration with humanitarian workers. The model allows analysis of the impact of alternative sourcing strategies and service level requirements on operational efficiency. It provides clear and actionable recommendations for a given context, bridging the gap between academics and humanitarian logisticians. The methodology was developed to be useful to a broad range of humanitarian organizations, and a specific application to the supply chain design of the International Federation of Red Cross and Red Crescent Societies is discussed in detail.

Published: October 2016

ABSTRACTIntroductionThe field of sexual medicine is continuously advancing, with novel outcomes reported on a regular basis. Given the rapid evolution, updated guidelines are essential to inform practicing clinicians on best practices.AimTo summarize the current literature and provide clinical guidelines on penile traction therapy, vacuum erection devices, and penile revascularization.MethodsA consensus panel was held with leading sexual medicine experts during the 2015 International Consultation on Sexual Medicine (ICSM). Relevant literature was reviewed and graded based on Oxford criteria to develop evidence-based guideline and consensus statements.Main Outcome MeasuresThe development of clinically relevant guidelines.ResultsPenile traction therapy is a viable therapy to modestly improve penile length as a primary therapy, before penile prosthesis placement in men with decreased penile length or after surgery for Peyronie's disease. It also might have a role in the acute phase of Peyronie's disease but has inconsistent outcomes in the long-term phase. Vacuum erection devices are effective in creating an erection satisfactory for intercourse, even in difficult-to-treat populations. They also might be used in the post-prostatectomy setting to maintain penile length but have insufficient evidence as a penile rehabilitation therapy. For vasculogenic erectile dysfunction, men with suspected arterial insufficiency can be evaluated with penile Duplex Doppler ultrasonography and confirmatory angiography. Penile revascularization procedures have consistently demonstrated benefits in very select patient populations; however, inadequate data exists to suggest the superiority of one technique. Men with vascular risk factors are likely poor candidates for penile revascularization, although veno-occlusive dysfunction and age are less significant. Therapies for treating primary veno-occlusive dysfunction are not recommended and should be reserved for clinical trials.ConclusionsSince the prior ICSM meeting, multiple developments have occurred in external mechanical devices and penile revascularization for the treatment of erectile and sexual dysfunction. Sexual medicine clinicians are encouraged to review and incorporate recommendations as applicable to their scope of practice.
