Effect and experiment of curvature radius of 3‐D printed conformal load‐bearing antenna array on EM performance

Prototypes of a special conformal load‐bearing antenna array (CLAA) which has nondevelopable surface, are designed, fabricated, and tested, and the effect of the substrate curvature radius on its EM performance is also researched in this work. A novel three‐dimensional (3‐D) printing technology and fabrication equipment based on micro‐droplet spraying and metal laser sintering are proposed to create patch array and divider network on a non‐developable curved rigid substrate. In order to compare with conventional technology (such as chemical etching), a planar CLAA prototype with two patches, operating frequency at 5GHz, is designed and fabricated by two different technologies, the surface roughness, fabrication tolerance, and EM performance are tested and compared. Finally, a spherical CLAA prototype with eight patches, operating frequency at 13GHz, is designed and fabricated by the novel 3D printing, measured EM performance demonstrate the applicability of additive manufacturing for this special CLAA.
Examining teachers’ classroom strategies to understand their goals for student learning around the science practices in the Next Generation Science Standards

ABSTRACT We report on seven secondary science teachers’ initial efforts to understand and enact NGSS-aligned teaching. After interviewing and observing them over the course of the school year, we found that teachers revised their lessons to include instructional strategies that aimed to meet the demands of the NGSS. Yet at times, the purpose for which teachers used these strategies were misaligned with the demands of the NGSS. This suggests that appropriately supporting teachers during this time of science education reform must include opportunities for them to consider their own instructional goals in relation to the goals and demands of the NGSS. We present the strategies and goals identified from interviews with the seven teachers and the observations of their classroom teaching in order to illustrate the professional learning needs of the in-service science teachers in this study.
An Overconfident CEO vs A Rational Board: The Tale About Bank Risk-Taking

Bank risk-taking behavior is of significant interest for researches and policy makers because financial failures due to excessive risk in this sector can have severe consequences for the bank’s numerous stakeholders and for the macroeconomic system overall. A growing literature investigates the main factors contributing to “well above average” risk. In particular, this study explains risk strategies in firms taking into account the bounded rationality of corporate governance agents. On a panel dataset of 110 listed US banks in the period of 2011-2016 empirical evidence is provided that excessive risk-taking in banks arises from the cognitive bias of the overconfidence of CEO decision-making. The study also presents how the impact of an overconfident CEO on risk-taking is affected considering the interaction of CEO overconfidence with the board of directors. It was revealed that the CEO's positive influence on risk is moderated if the board is an effective monitoring mechanism with the presence of independent directors who are experts in the financial sphere
Segmental Bone Muscle and Skin Cross Leg Flap for the Treatment of Posttraumatic Infected Segmental Bone Defect in a Child- A Case Report

A mangled limb in a pediatric patient produces therapeutic dilemma whether to amputate or salvage greater than in adult. We herein present a case of a 10 year old child with high energy injury to both lower limbs. The bone muscle and skin segment of the limb planned for amputation has been used as a “spare part” for the contralateral shin defect in order to save at least one weight bearing limb. The cross leg flap has been successful. The patient walks without limp using PTB prosthesis. No recurrence of infection was observed within 10 years post-op. We conclude that the limb salvage attempt in a child should be based more on surgeon decision rather than strict guidelines and is always worth trying.
Approaching overload: diagnosis and response to anomalies in complex and automated systems

Web production software systems operate at an unprecedented scale today, requiring extensive automation to develop and maintain services. The systems are designed to regularly adapt to dynamic load to avoid the consequences of overloading portions of the network. As the software systems scale and complexity grows, it becomes more difficult to observe, model, and track how the systems function and malfunction. Anomalies inevitably arise, challenging incident responders or SREs to recognize and understand unusual behaviors as they plan and execute interventions to mitigate or resolve the threat of service outages. A study of four real cases reveals the interplay between the human and machine agents when problems disrupt the system. The analysis of the incidents directly links the cascade of disturbances below the line of representation (e.g. computer interfaces, monitoring tools) with the cognitive work of Site Reliability Engineers. The Above the Line / Below the Line Framework (ABL) changes the perspective in reviewing the cases post mortem in the tradition of Cognitive Systems Engineering and Resilience Engineering. The case study demonstrates specific and general patterns for complications to incident management in complex web operation systems, as well as directions for designing better tooling to support future, resilient work.
Understanding Pre-Service Teachers’ Legal Literacy and Experiences with Legal Issues in Practicum Placements: An Exploratory Study

There is a dearth of research that examines legal literacy among pre-service teachers in Canada. Pre-service teachers’ legal literacy refers to the knowledge level that teacher candidates in teacher education programs have with respect to educational law and policy and how it affects their preparation for entering the teaching profession. This article presents findings from an exploratory mixed-methods study that examined teacher candidates’ (n=1731) reflections that detailed observations of and experiences with legal issues while on practicum placements in a teacher education program in one southeastern Ontario university during three academic years. We identify teacher candidates’ most frequently cited aspects of school law and policy; analyze teacher candidates’ awareness of school laws and policies pertaining to those aspects; and, explore their perceived preparedness to deal with legal issues occurring in their practicum placements. We conclude with the discussion of findings and research implications for teacher education programs.
Virulence Gene Constellations Associated with Lethality in Avian Pathogenic E. coli Recovered from Broiler Chickens

| In this study, avian pathogenic E. coli (APEC) isolated from broiler chickens in Fayoum and Beni-Suef governorates in Egypt were morphologically and biochemically identified. Selected isolates were serologically identified, and their antimicrobial susceptibility profiles were determined. Ten isolates from the most predominant serogroups were subjected to virulence and antimicrobial resistance genes detection using PCR. In vivo pathogenicity test was performed for 5 E. coli strains that were selected based on serogroups prevalence, virulence, and antimicrobial genes patterns. Results revealed an incidence of 53.8% of E. coli from broiler chickens with the predominance of O125 (30%), O119 (20%), O126, and O86a (15% each) serogroups. The selected 20 E. coli strains were multi-drug resistant (MDR) but sensitive to fosfomycin. The β-lactams and tetracyclines resistance genes were detected in all tested isolates, however, aminoglycoside and quinolone resistance genes were not detected. In this study, 10% of isolates were resistant to colistin and the mcr-1 gene was detected by PCR. In vivo pathogenic strains consistently harbored the virulence gene pattern of fimH, fimA, papC, iutA, and tsh which was the most common gene constellation detected. The detection of tsh gene was consistently associated with lethality in day-old chicks. In conclusion, the current study demonstrated the high prevalence of multidrug-resistant E. coli in broiler chickens representing a potential public health concern. Additionally, the virulence gene constellation of fimH, fimA, papC, iutA, and tsh was found to be associated with lethality in day-old chicks and can be used as a virulence marker of APEC.
Adaptation to climate change and conservation of biodiversity using green infrastructure

In recent years, we have experienced mega‐flood disasters in Japan due to climate change. In the last century, we have been building disaster prevention infrastructure (artificial levees and dams, referred to as “grey infrastructure”) to protect human lives and assets from floods, but these hard protective measures will not function against mega‐floods. Moreover, in a drastically depopulating society such as that in Japan, farmland abandonment prevails, and it will be more difficult to maintain grey infrastructure with a limited tax income. In this study, we propose the introduction of green infrastructure (GI) as an adaptation strategy for climate change. If we can use abandoned farmlands as GI, they may function to reduce disaster risks and provide habitats for various organisms that are adapted to wetland environments. First, we present a conceptual framework for disaster prevention using a hybrid of GI and conventional grey infrastructure. In this combination, the fundamental GI, composed of forests and wetlands in the catchment (GI‐1) and additional multilevel GIs such as flood control basins that function when floodwater exceeds the planning level (GI‐2) are introduced. We evaluated the flood attenuation function (GI‐1) of the Kushiro Wetland using a hydrological model and developed a methodology for selecting suitable locations of GI‐2, considering flood risk, biodiversity and the distribution of abandoned farmlands, which represent social and economic costs. The results indicated that the Kushiro Wetland acts as a large natural reservoir that attenuates the hydrological peak discharge during floods and suitable locations for introducing GI‐2 are concentrated in floodplain areas developing in the downstream reaches of large rivers. Finally, we discussed the network structure of GI‐1 as a hub and GI‐2 as a dispersal site for conservation of the Red‐crowned Crane, one of the symbolic species of Japan.
Hydroelastic Analysis and Validation of an End-Anchored Floating Bridge Under Wave and Current Loads

Analysis tools used by the offshore industry are applied for prediction of global dynamic behaviour of the extreme floating bridge concepts being evaluated by the Norwegian Public Roads Administration (NPRA). Validation and code-code comparison of these analysis tools are of significant importance when they are applied to such new and non-traditional structures. The current paper focus on validation between numerical modelling and model tests. An end-anchored floating bridge of around 850m length is studied. A hydro-elastic global analysis model was created by considering the bridge as large radiation/diffracting floaters connected by elastic beams. The analysis has been done both in frequency and time domain, by including the hydrodynamic interaction between the pontoons or not. A systematic check of different parameters that may have impact on the analysis was carried out. The numerical results have been compared with the model tests carried out in MARINTEK (1990). The work provides validation of the current analysis tools and guidelines for future work.
Displaced Distal Radius Fractures Presented Late: A Randomized, Prospective Comparative Study of Two Methods of Treatment

BACKGROUND AND AIM OF THE WORK: Fractures of the distal radius are common, yet there is no clear consensus on their management. A fracture that slips after reduction should be considered to be unstable and probably requires fixation. Latepresenting cases come with more complexity. This study aims to evaluate the early results of a minimally invasive surgery by the modified Kapandji technique versus invasive surgery through open reduction and internal fixation by plate and screws in treating these challenging fractures. RESEARCH DESIGN AND METHODS: Prospective study restricted for those adult patients with displaced distal radius fractures presented within 3 to 6 weeks from date of injury. The study patients were randomly divided into two groups each one included 23 patients. Group I, managed with Kapandji method, as modified by Fritz et al. and group II was treated by the conventional open reduction and internal fixation by plate and screws. RESULTS: The result at final follow-up was excellent in 63.2%, good in 26.3%; fair in 10.5% and no poor results in group I compared to 66.6% excellent, 23.9% good, 9.5% fair and no poor results in group II. CONCLUSIONS: Excellent to good results can be achieved in most of cases. As no significant difference in outcome between the two ways, the modified Kapandji technique is preferred as it is less invasive, easy to perform, less costly and time saving.
Hierarchical Chestnut-Burr Like Structure of Copper Cobalt Oxide Electrocatalyst Directly Grown on Ni Foam for Anion Exchange Membrane Water Electrolysis

Uniquely nanostructured CuCo2O4 is presented as an electrocatalyst for oxygen evolution reactions (OER). CuCo2O4 particles in a chestnut-burr-like shape (CCO*, where ∗ = chestnut burr) were hydrothermally synthesized around fibers of Ni foam substrates as current collectors. Chestnut burrs 4 μm on average had thorns consisting of less than five threads. Each thread was made of a consecutive array of nanobeads less than 10 nm. Nanovoids or nanopores were found between nanobeads. The chestnut-burr structure of CCO* allowed IrO2-overwhelming OER activity. By using the hierarchically nanostructured electrocatalyst directly grown on current collectors without binders and conducting agents, high performances of anion exchange membrane (AEM) electrolysis was demonstrated. Three merits of the electrode architecture were emphasized. First, mass transfer pathways for reactants and products were secured in a microscale between thorns and in a nanoscale between nanobeads. Second, more active sites were exposed to ele.
11. Ludo-epistemology: Playing with the rules in citizen science games

In their chapter, Glas and Lammes critically investigate the limitations of citizen science game design when it comes to having amateurs playfully participate in the production of scientific knowledge. Moving away from the traditional distance between the scientist as expert and the citizen as layperson, and between science as serious and play as trivial, they argue for a recognition of play as fundamental to the scientific endeavor and see rule breaking and bending as an essential part of this process. From this perspective, they consider an approach to citizen science game design that includes playing with the rules as a more critical way of having citizens think about and participate in science.
The Effect of Electronic Service Quality on Customers Satisfaction and Loyalty in Online Shopping

The purpose of this study is to measure the influence of electronic service quality on customers satisfaction and loyalty in online shopping setting. This study used quantitative method. The questionnaires were distributed online. Of the 305 returned questionnaires, 282 were valid for further data analysis. SEM PLS was used to test the hypothetical analysis. The results reveal that electronic service quality has a positive and significant influence on satisfaction. Also, consumer satisfaction influences positively and significantly on loyalty. The indirect effect of electronic service quality on loyalty is higher compared to its direct effect. This means that satisfaction is an important variable in shaping customers loyalty. In addition, the dimensionality of electronic service quality needs to be further tested. Theoretically, this study provides a better understanding of the relationship between electronic service quality, satisfaction, and loyalty in an online shopping context. Practically this study contributes to the online shop businesses by providing evidence on the importance of electronic services quality dimensions and the need to satisfy customers to get their loyalty. It can be concluded that Online shop businesses need to determine and focus on relevant electronic service quality dimensions to build their online shop competitiveness and to set their online shop apart from the crowd.
A Mathematical Model of the Cognitive Semantics of the English Preposition ON

This study aims to present a mathematical linguistic analysis in establishing the relations between TRs, LMs, potential senses, and actual senses by using the case of the preposition on found in academic texts under the framework of Trajector (TR) and Landmark (LM) configurations. Data were corpora taken from 10 bachelor’s theses written by Indonesian students. To sort the data, Ant Conc 3.4. 1.0 was used to parse clauses or sentences based on the TR-LM configurations. Based on the TR-LM configurations, a mathematical model was developed to discover how these variables are quantitatively related to the number of potential senses produced by using a geometric representation of TR and LM. This study indicates that the relation between TRs and LMs, on the one hand, and the sum of potential senses, on the other, follows the integral function of , which means that the total number of potential senses of Ps equals the integral of TR with respect to LM. Meanwhile, the total number of actual senses, ∑As can be obtained by the integral function of , which equals TR.LM + C where C is -Ls representing the constant of the number of lost senses. This mathematical modeling confirms that TR-LM configurations may be used to generate senses which prove the polysemous nature of prepositions.
Fashioning My Garden of Solace: A Black Feminist Autoethnography

Abstract Through the lens of Black feminist autoethnography and (auto)biographical narrative, this article makes an impactful contribution to postcolonial feminist thought, fashion and cultural studies. I consider the significance of fashion and material culture as sociopolitical strategies of presence that offer an unparalleled understanding of my unique lived experience as a Ghanaian-Cameroonian-American Black woman. By exploring the intergenerational legacy of how my mother and I actively navigate the dichotomy of hypervisible, yet unseen, this article further considers the emancipatory potential and underacknowledged legacy of Black women’s contributions to aesthetic and visual culture through embodied activism located within the practice of horticulture and gardening, alongside self-fashioned identity.
Handling data skew at reduce stage in Spark by ReducePartition

As a typical representative of distributed computing framework, Spark has been continuously developed and popularized. It reduces the data transmission time through efficient memory‐based operations and solves the shortcomings of the traditional MapReduce computation model in iterative computation. In Spark, data skew is very prominent due to the uneven distribution of input data and the unbalanced allocation of default partitioning algorithm. When data skew occurs, the execution efficiency of the program will be reduced, especially in the reduce stage of Spark. Therefore, this paper proposes ReducePartition to solve data skew problem at reduce stage of Spark platform. First, the compute node samples the local data according to the sampling algorithm to predict the overall characteristics of data distribution. Then, to take full use of cluster resources, ReducePartition divides data into multiple partitions evenly. Next, taking into account the differences in computational capabilities among Executors, each task is assigned to Executor with the highest performance factor according to the greedy strategy. Finally, the results of the related algorithms and ReducePartition are compared by using WordCount benchmark and Sort benchmarks on heterogeneous Spark standalone cluster. The performance of the ReducePartition under different degree of data skew and different data size is analyzed. Experimental results show that the proposed algorithm can effectively reduce the impact of data skew on the total makespan of Spark big data applications, and the average total makespan is reduced by 30% to 50% while resource utilization is increased by 20%‐30% on average.
Tracheal measurement by computed tomography in Korean adults

-Tracheal The knowledge of normal tracheal morphology is helpful during endotracheal intubation for anesthesia as well as detecting tracheal and paratracheal disorders. Tracheal measurement by simple X-ray is not accurate due to image imagnification and overlapping of the shoulders in the lateral proje다ion. CT , however , is highly accurate to measure the normal tracheal morphology and paratracheal anatomy. The study was undertaken to obtain standard values of normal Korean tracheae. 50 neck and mediastinal pathology respiratory
Students' experiences of human-centred interventions in a design education setting

International and national developments in graphic design practice have incorporated unprecedented levels of engagement with end-user clients and audiences. However, instructional graphic design courses for undergraduates have not kept pace with this trend or with associated professional practice expectations. Traditionally, graphic design practice relies on the ‘expert’, autocratic knowledge of the designer regarding the expected outcomes of the design brief. The use of co-operative tools and techniques such as human-centred design (HCD) enables the process to become a more democratic co-creation experience, where the client participants actively contribute to the development of the final design product. To prepare students for the new relationship between designers and end-users, newly developed HCD project interventions were created as part of the Communication Design modules offered in the third year Graphic Design Diploma programme at a University of Technology in South Africa. This paper reports on two human-centred interventions in different settings and involving different types of stakeholders, with a view to analysing the experiences of students as they conducted the projects to assess the viability of the HCD projects towards establishing a proposed new curriculum that incorporates aspects of HCD as a fundamental approach to graphic design practice.
