Walking Dead Literacies: Zombies, Boys, and (Re)Animated Storytelling
Authors: Wessel‐Powell Christy , Lu Ya‐Huei , Wohlwend Karen 
Published: May 2018

AbstractIncreased emphasis on standardization in primary grades can stifle spontaneous literacy play. The authors argue that allowing playful, collaborative, multimodal literacies into primary classrooms and specifically in writers’ workshop can expand and enliven the way we see students’ literacy strengths. The authors look closely at the unique storytelling processes and final performance of a grades K–1 collaborative storytelling group, the Zombie Boys. This group worked over several weeks during workshop/playshop to produce an original story line rich in special effects, music, synchronized dance, puppets, backdrop, and props design and delivered a meaningful and entertaining play performance. The authors also demonstrate possibilities in expanded, equitable literacy assessment for primary grades by using a multimodal checklist and story line graph to gauge narrative complexity and story shape, tracking the group’s minilesson uptake, and describing how peers and teachers received the group’s story when performed for feedback.
Quantification of the S817 airfoil aerodynamic properties and their control using synthetic jet actuators
Authors: Rice Thomas T. , Taylor Keith , Amitay Michael 
Published: May 2018

AbstractWind tunnel experiments were conducted at Rensselaer Polytechnic Institute's Center for Flow Physics and Control's subsonic wind tunnel, which experimentally quantified the aerodynamic performance of the S817 airfoil. This study has two main thrusts: Experimentally evaluate common aerodynamic properties of the S817 airfoil, and develop flow control strategies using continuously actuated and pulse‐modulated synthetic jets for future field testing to show the reduction of unsteady loading and increased aerodynamic performance. Quasi‐2D and finite span 3D configurations were utilized, where integrated aerodynamic loading, surface pressure, and stereoscopic particle image velocimetry data were collected to quantify the overall aerodynamic performance and stall characteristics of this airfoil. Experiments showed that synthetic jets, located at x/c=0.35 and angled at 45° with respect to the surface, increased the lift curve slope by 3.8%, the maximum lift coefficient by 10.5%, increased the L/D by as much as 39% at high angles of attack and delayed the stall angle of attack by 3°. Global particle image velocimetry measurements quantified the flowfield and showed flow reattachment could be achieved at various angles of attack using flow control where the flow would otherwise be separated. Near field measurements of the synthetic jet orifice yielded insight as to how synthetic jets interact with the cross‐flow in the time‐ and phase‐averaged sense. For very high angles of attack, a pulsed modulation technique was implemented, demonstrating flow reattachment in scenarios where a sinusoidal synthetic jet actuation scheme was unable to reattach the flow, with the benefit of achieving this with lower energy consumption compared with sinusoidal actuation.
Cosmic User Story Standard
Authors: Ecar Miguel , Kepler Fabio , da Silva João Pablo S. 
Published: May 2018

AbstractUser Story is a technique widely used in Agile development. It is characterised as short and high level descriptions of required functionality, written in customer language during the very early requirement gathering stage and containing just enough information to produce the estimated implementation effort. The COSMIC method is a second generation technique for function size measurement. The requirement estimation precision in COSMIC is directly proportional to the requirement detailing level. Current templates for user stories writing might ignore important information for COSMIC measurement purposes. This paper introduces a new template for writing user stories which is more expressive in terms of COSMIC size estimation. We performed a qualitative survey to introduce this new user story template to the COSMIC community, intending to capture the COSMIC users opinion in terms of expressiveness and how valuable it is. The survey points to promising results considering the COSMIC users opinion about the new template. This study contributes to agile requirements from the COSMIC users point of view. This new template may be a step forward in terms of user story estimation for COSMIC sizing based projects.
Agile Software Development – Adoption and Maturity: An Activity Theory Perspective
Authors: Chita Pritam 
Published: May 2018

AbstractThis paper suggests that Activity Theory is a useful lens for examining aspects of agile software development adoption and maturity. Implementing agile approaches is influenced by many factors and attention is focused on individual and collective software development activity within an organisation’s socially constructed environment. The research aim is to examine specific organisational, historical, cultural and social hindrances and facilitators that impact individual and collective learning opportunities and subsequent implementation of agile practices. This paper reports on the initial stages of research that consisted of a series of interviews and a survey. The results indicate that socially constructed hindrances and tensions are wide spread and vary in the levels at which they occur. They also correlate with many of the factors that influence agile maturity that have already been identified within the literature. This study contributes to research by integrating elements of learning theory and agile software development practice.
Supporting Large-Scale Agile Development with Domain-Driven Design
Authors: Uludağ Ömer , Hauder Matheus , Kleehaus Martin , Schimpfle Christina , Matthes Florian 
Published: May 2018

AbstractAn increasing number of large organizations are adopting agile and lean methods at larger scale for building complex software systems. One major critique of agile development and in particular of large-scale agile development is the neglect of proper architecting assistance in such development efforts. On the one hand, emergent architecture design may require excessive redesign efforts in large systems, while on the other hand, big upfront architecture delays the starting point of implementation. Domain-driven Design (DDD) addresses this problem by providing means for evolving the architecture of complex systems in an agile way. We describe how DDD can support large-scale agile development based on a conducted case study in a large insurance company with three agile teams. Furthermore, we present a lightweight framework that can be used by agile teams as guidance for architecting in large-scale agile development programs. The presented framework is largely based on Large-Scale Scrum and incorporates strategic and tactical DDD.
Stress in Agile Software Development: Practices and Outcomes
Authors: Meier Andreas , Kropp Martin , Anslow Craig , Biddle Robert 
Published: May 2018

AbstractStress is an important workplace issue, affecting both the health of individuals, and the health of organizations. Early advocacy for Agile Software Development suggested it might help avoid stress, with practices that emphasize a sustainable pace, and self-organizing teams. Our analysis of a 2014 survey, however, suggested that stress might still be commonplace in Agile teams, especially for those with less experience. We also noticed that newcomers to Agile emphasized technical, rather than collaborative, practices, and speculated this might explain the stress. We explored this in our analysis of a follow-up survey conducted in 2016, and report our findings in this paper. We show that there are a variety of factors involved, and that avoiding stress is associated with both collaborative and technical practices, and a range of outcomes.
Improving Mockup-Based Requirement Specification with End-User Annotations
Authors: Urbieta Matias , Torres Nahime , Rivero José Matias , Rossi Gustavo , Dominguez-Mayo F. J. 
Published: May 2018

Abstract
Agile approaches, one of the key methodologies used in today’s software projects, often rely on user interface mockups for capturing the goals that the system must satisfy. Mockups, as any other requirement artifact, may suffer from ambiguity and contradiction issues when several points of view are surveyed/elicited by different analysts. This article introduces a novel approach that enhances mockups with friendly end-user annotations that helps formalizing the requirements and reducing or identifying conflicts. We present an evaluation of the approach in order to measure how the use of annotations improves requirements quality.
Software Tester, We Want to Hire You! an Analysis of the Demand for Soft Skills
Authors: Florea Raluca , Stray Viktoria 
Published: May 2018

Abstract
One important discussion in the software development field is related to the skills that people need to have to build successful software products. This debate is generated on one hand by a large number of failures and delays of software projects. On the other hand, the debate is triggered by the need to build even better-quality software in a rapidly changing world. We will examine to which extent soft skills are relevant when hiring software testers and if there are any specific skills required for agile testers.We analyzed 400 job advertisements for testers from 33 countries, out of which 64% ask for soft skills. Of the advertisements asking for soft skills, there is, on average, a request for 5 soft skills, 11 testing skills, and 5 technical skills. Only 30% of the companies ask explicitly for agile testers. However, our analysis shows no notable differences in skill demands for agile testers and the rest.Software companies want to hire testers who can communicate well and have analytical and problem-solving skills. There is a significant increase in the need for openness and adaptability, independent-working and team-playing since 2012. In addition, there are new categories of soft skills identified, such as having work ethics, customer-focus and the ability to work under pressure.

Published: May 2018

Abstract
Objectives
The biocompatible 2-methacryloyloxyethyl phosphorylcholine (MPC)-polymers, which mimic a biomembrane, reduce protein adsorption and bacterial adhesion and inhibit cell attachment. The aim of this study is to clarify whether MPC-polymer can suppress the bacterial adherence in oral cavity by a crossover design. We also investigated the number of Fusobacterium nucleatum, which is the key bacterium forming dental plaque, in clinical samples.

Materials and methods
This study was a randomized, placebo-controlled, single-blind, crossover study, with two treatment periods separated by a 2-week washout period. We conducted clinical trial with 20 healthy subjects to evaluate the effect of 5% MPC-polymer mouthwash after 5 h on oral microflora. PBS was used as a control. The bacterial number in the gargling sample before and after intervention was counted by an electronic bacterial counter and a culture method. DNA amounts of total bacteria and F. nucleatum were examined by q-PCR.

Results
The numbers of total bacteria and oral streptcocci after 5 h of 5% MPC-polymer treatment significantly decreased, compared to the control group. Moreover, the DNA amounts of total bacteria and F. nucleatum significantly decreased by 5% MPC-polymer mouthwash.

Conclusions
We suggest that MPC-polymer coating in the oral cavity may suppress the oral bacterial adherence.

Clinical relevance
MPC-polymer can be a potent compound for the control of oral microflora to prevent oral infection.

AbstractMiscarriage due to fetal tumors is an extremely rare finding, with a varying incidence from 1.7 to 13.5 per 100,000 live births, with central nervous system tumors occupying a minority of these cases. Herein, we report the gross morphological and histological findings of a 17-gestational week spontaneous miscarriage in a 27 year old multi-gravida due to a fourth ventricle choroid plexus papilloma (CPP). The CPP was composed of a pronoun fibro-vascular stroma covered with a dense lining of tall cuboid sparsely ciliated single cell layer with rich in chromatin nuclei. The cytoplasm of the CPP covering cells was intensely colored when compared to the pale cytoplasm of the covering cells of the choroid plexus collected from the lateral ventricle, which also lacked in such pronoun fibrovascular stroma. The fourth ventricle was significantly dilated with parenchymal compression of nervous tissue towards the chondral fetal cranium.
A Real-World Evidence Study Assessing the Impact of Adding the Aerobika Oscillating Positive Expiratory Pressure Device to Standard of Care Upon Healthcare Resource Utilization and Costs in Post-Operative Patients

Abstract
Introduction
The aim of this real-world study was to measure the benefit of the Aerobika oscillating positive expiratory pressure (OPEP) device when added to standard of care (defined as incentive spirometry [IS]) for post-operative patients.

Methods
Adults aged ≥ 18 years who were hospitalized for cardiac, thoracic or upper abdominal surgery between 1 September 2013 and 30 April 2017 were identified from IQVIA’s Hospital Charge Detail Master (CDM) database; the index date was the date of the first hospitalization for surgery. The control cohort (IS) included patients who had ≥ 1 CDM record within 12 months prior to the index date and ≥ 1 record after discharge, evidence of IS use during index hospitalization and no evidence of use of a PEP or OPEP device at any time during the study period. The Aerobika OPEP cohort was selected in a similar manner, except that patients were required to have evidence of Aerobika OPEP use during the index hospitalization. Aerobika OPEP patients were 1:1 matched to IS patients using propensity score (PS) matching. Hospital readmissions and costs were measured at 30 days post-discharge from the index hospitalization.

Results
After PS matching, 144 patients were included in each cohort. At 30 days post-discharge, compared to the control (IS) cohort there were significantly fewer patients in the Aerobika OPEP cohort with ≥ 1 all-cause re-hospitalizations (13.9 vs. 22.9%; p = 0.042). The patients in the Aerobika OPEP cohort also had a shorter mean length of stay (± standard deviation) (1.25 ± 4.04 vs. 2.60 ± 8.24 days; p = 0.047) and lower total unadjusted mean all-cause cost per patient ($3670 ± $13,894 vs. $13,775 ± $84,238; p = 0.057). Adjusted analyses suggested that hospitalization costs were 80% lower for the Aerobika OPEP cohort versus the IS cohort (p = 0.001).

Conclusion
Our results suggest that the addition of the Aerobika OPEP device to standard of care (IS) is beneficial in the post-operative setting.

Simulating network intervention strategies: Implications for adoption of behaviour
Authors: BADHAM JENNIFER , KEE FRANK , HUNTER RUTH F. 
Published: May 2018

AbstractThis study uses simulation over real and artificial networks to compare the eventual adoption outcomes of network interventions, operationalized as idealized contagion processes with different sets of seeds. While the performance depends on the details of both the network and behaviour adoption mechanisms, interventions with seeds that are central to the network are more effective than random selection in the majority of simulations, with faster or more complete adoption throughout the network. These results provide additional theoretical justification for utilizing relevant network information in the design of public health behavior interventions.
An improved kinematic calibration method for serial manipulators based on POE formula
Authors: Chang Chenguang , Liu Jinguo , Ni Zhiyu , Qi Ruolong 
Published: May 2018

SUMMARYExisting measurement equipments easily determine position with high precision. However, they evaluate orientation with low precision. It is necessary to minimize the effect of measurement error on identification accuracy. In this study, a method for kinematic calibration based on the product of exponentials (POE) is presented to improve the absolute positioning accuracy of a sliding manipulator. An error model with uniform and generic modeling rules is established in which the tool frame is selected as the reference frame. Furthermore, the redundant parameters of the error model are removed. Subsequently, the actual kinematic parameters are identified by using the least square method. Finally, the process of the improved method is discussed. Kinematic calibration simulations of a sliding manipulator are implemented. The results indicate that the proposed method significantly improves the precision of the sliding manipulator. The improved POE kinematic calibration method offers convenience, efficiency, and high precision. The proposed method can be applied to all types of serial robots withn-DOF
Isomorphism of uniform algebras on the 2-torus
Authors: PETERS JUSTIN R. , SANYATIT PREECHAYA 
Published: May 2018

AbstractFor α a positive irrational, let 𝛢α be the subalgebra of continuous functions on the two-torus whose Fourier transform vanishes at (m, n) if m+αn &lt; 0. These algebras were studied by Wermer and others, who proved properties such as maximality and characterised the Gelfand space. One of the major themes of current work in operator algebras is classification, but none of the properties which were investigated earlier distinguished between 𝛢α and αβ, if β is another positive irrational. We address this question. We also determine the automorphism group of 𝛢α.

ABSTRACTGood education requires student experiences that deliver lessons about practice as well as theory and that encourage students to work for the public good—especially in the operation of democratic institutions (Dewey 1923; Dewy 1938). We report on an evaluation of the pedagogical value of a research project involving 23 colleges and universities across the country. Faculty trained and supervised students who observed polling places in the 2016 General Election. Our findings indicate that this was a valuable learning experience in both the short and long terms. Students found their experiences to be valuable and reported learning generally and specifically related to course material. Postelection, they also felt more knowledgeable about election science topics, voting behavior, and research methods. Students reported interest in participating in similar research in the future, would recommend other students to do so, and expressed interest in more learning and research about the topics central to their experience. Our results suggest that participants appreciated the importance of elections and their study. Collectively, the participating students are engaged and efficacious—essential qualities of citizens in a democracy.
A “WHITE BOY . . . WHO IS NOT A WHITE BOY”: RUDYARD KIPLING'SKIM, WHITENESS, AND BRITISH IDENTITY
Authors: Walters Alisha 
Published: May 2018

Rudyard Kipling's final novel,Kim(1901), begins with an intriguing – if paradoxical – description of the eponymous Kim, or Kimball O'Hara: he is an “English” boy with an Irish name and Irish parentage who speaks “the [Indian] vernacular by preference” (1). While the narrator hastens to reassure the reader that Kim is both “white” and “English,” Kim is also “burned black as any native” and speaks his supposed “mother tongue,” English, in an “uncertain sing-song” (1). If we are to take Kipling's assertion at face value, that Kim is, indeed, “English,” then certainly this is a kind of Englishness that is divorced completely from the racially pure ideals of Anglo-Saxon whiteness that were privileged by many racial theorists earlier in the nineteenth century. As an Irish Celt, Kipling's protagonist is always already at a layer of remove from ideals of pure Englishness, but Kipling renders Kim's racial identity even more complicated in the text. The manuscript ofKimgives us some telling clues about the contexts that inform Kipling's peculiar descriptions of “burned black” whiteness in his finished novel. While the published text baldly declares that “Kim wasEnglish. . . . Kim was white” (1; ch. 1; emphasis mine), parts of the manuscript are much less certain of this fact, as that document asserts that Kim “looked like a half caste” (Kipling,Kim o’ the ‘Rishtin. 3). And while Kipling ultimately removed this explicit link between Kim and Eurasian bodies in the opening of his published text, this disavowal is neither complete nor convincing throughoutKim. For instance, in the novel, the narrator later describes a “half-caste woman who looked after [Kim . . . and] told the missionaries that she was Kim's mother's sister” (1; ch. 1). While this woman is not, in fact, the boy's aunt, Kim's near-familial tie with her underlines the intimate connection between him and the hybridized subjects of empire. Indeed, Kim demonstrates ideological and affective links to non-white Others and to people of mixed race, and this connection between whiteness and racial hybridity is of central importance to Kipling. If Kim is tenuously white, then he can only perform this whiteness in immediate proximity to racial hybridity, with which whiteness is ideologically contiguous in this text. As I contend in this paper,Kimreveals the under-examined links between early twentieth-century ideas of white British identity and descriptions of imperial miscegenation. InKim, “White” and “English” emerge as a vexed pair of signifiers that reveal unprecedented traces of racial and national hybridization.
