MASTER PLAN TO ROBUST PRACTICE: THE EVOLUTION OF SUSTAINABLE LANDSCAPE PRACTICES AT GEORGIA INSTITUTE OF TECHNOLOGY
Authors: Ide Hyacinth , Rose Jessica
Published: August 2018

INTRODUCTION

Universities across the globe are recognizing the need to implement sustainable landscaping practices in order to support wildlife, improve water quality and positively impact human health and wellbeing. Georgia Institute of Technology learned that such sustainable practices, when properly aligned with overarching campus goals, can also enable continuous, collaborative decision-making and student engagement.

The Georgia Institute of Technology (Georgia Tech) is a leading research university situated on 426 acres of land in midtown Atlanta, Georgia, with a student population of 27,000 (Fall 2017). An urban oasis in the center of town, Georgia Tech's campus offers 312.5 landscaped acres, 3.5 naturalized acres and 110 acres of buildings. The campus is also a level II certified arboretum boasting 12,000+ trees in its urban forest.

Prior to the 1990s, Georgia Tech was commonly referred to as a concrete and brick campus with very little landscape. However, in 1999 all that changed when the Georgia Tech administration decided to invest in sustainable landscaping, including the recruitment of qualified staff with specific skill sets to take on this challenge. The Institute's initial landscape master plan objectives were to reduce impervious surfaces such as surface parking lots, increase woodland coverage and enlarge the tree canopy.

A significant amount of sustainable landscape practices and collaborative methods grew from these initial objectives. Establishing a plan with clear goals, having the support of executive leadership and employing the right team members enabled the Georgia Tech campus to be transformed from a concrete jungle to a forested, urban oasis in less than 20 years.
URBAN PHOTOVOLTAIC POTENTIAL OF INCLINED ROOFING FOR BUILDINGS IN HERITAGE CENTERS IN EQUATORIAL AREAS

In situ renewable energy production is a favourable alternative for reducing pollution and combating climate change. The research area, Cuenca, Ecuador, is located in the Andes near the equator with optimal conditions for energy self-supply due to its low energy demands and low levels of irradiation variability. In this study, temporary fluctuations in consumption based on 2016 electricity consumption data are characterized. Using GIS, available roofing polygons are obtained, and the amount of usable solar radiation is estimated based on these values. With available surface, orientation, and inclination information, electricity generation based on photovoltaic performance is estimated and compared for monocrystalline silica panels and photovoltaic solar roof tiles, which are architectural alternatives. A potential net supply of 148% is found for monocrystalline silica photovoltaic panels in a typical format, whereas that of photovoltaic tiles is only 61%. In addition, production-demand imbalances are predicted in extreme months and average months and on extreme days due to variations in irradiation and demands.
COMPARISON OF GREEN HOME ENERGY PERFORMANCE BETWEEN SIMULATION AND OBSERVATION: A CASE OF VIRGINIA, UNITED STATES
Authors: McCoy Andrew P. , Zhao Dong , Ladipo Teni , Agee Philip , Mo Yunjeong
Published: August 2018

The United States has a long-term goal to reduce 50% of energy usage in buildings based on 2010 consumption levels. Home energy efficiency is often measured by laboratory experiments and computational simulation. Thus, there is little to no quantifiable evidence showing the extent of energy efficiency homes can achieve within the larger context of green building standards. The objective of this research is to identify actual home energy performance as an effect of green building technologies by comparing energy use from real-world observations and energy modeling. Results indicate a significant reduction of energy consumption at 43.7% per unit or 43.4% per square foot (i.e., 0.093 m2) and substantial financial savings at $628.4 per unit or $0.80 per square foot (i.e., $8.6 per m2) annually. Savings account for 2% of median annual household income or 46% of energy cost expenditures for an American home. Results also identify the construction type as a significant factor, yet building technology is not the only factor influencing a home's energy efficiency. The findings contribute to the body of knowledge in three aspects: (1) simulated energy usage is higher than actual energy usage; (2) energy modeling via simulation tools is particularly accurate for new construction; and (3) energy modeling, especially for existing buildings, is not accurate due to largely varying occupant behaviors.
Effect of radiation inside square hollow section under moderate non-symmetric fire
Authors: Bączkiewicz Jolanta , Pajunen Sami , Heinisuo Markku
Published: August 2018

The temperature calculation of hollow steel sections at elevated temperatures is a well-documented and standard procedure. Through this standard procedure, the temperature can be calculated by assuming a uniform gas temperature all around the section, which is called a symmetric fire in this paper. Embedding in surrounding structures or connecting to another steel member results in non-symmetric heat distribution in the member. This non-symmetricity of the surrounding temperature may cause surface- to-surface heat radiation inside the member, thus affecting the steel section temperature distribution. This effect is considered in this paper by adopting analytical and finite element method analysis.
Pre-emergence growth and development in the arctic midge Trichotanypus alaskensis Brundin
Authors: Butler Malcolm G. , Braegelman Shane D.
Published: August 2018

Developing at low mean temperatures, arctic chironomids often have prolonged larval growth yet adult emergence is typically a brief and highly synchronous event. How does a midge population achieve synchronous emergence? Under the Absolute Spring Species Hypothesis (AbSS), adult eclosion by early-emerging species may be synchronized by overwintering as fully mature larvae. Such prepupal larvae would neither feed nor grow after spring thaw, only pupate and emerge. The podonomine Trichotanypus alaskensis Brundin is an abundant midge in tundra ponds on Alaska’s Arctic Coastal Plain, and one of the earliest-emerging species in this chironomid-dominated insect community. T. alaskensis is univoltine in these arctic ponds, with most emergence from any one pond occurring within less than a one-week span during late June, typically about three weeks after pond thaw. We evaluated T. alaskensis for conformity to the AbSS model by documenting the overwintering state of this species in a tundra pond near Barrow, Alaska, then monitoring larval growth and development of the population from spring thaw to pupation. Most T. alaskensis were immature instar IV larvae when collected in late September of both 2010 and 2011, with 10-30% still in late instar III. Immediately after pond thaw in 2011, all collected larvae had imaginal disc primordia showing early stages of instar IV development. Within the first two weeks following pond thaw, most larvae had doubled their dry mass and developed into mature (prepupal) final-instar larvae. Highly synchronized emergence by T.  alaskensis is not a consequence of a population overwintering as fully-mature larvae, as per the Absolute Spring Species Hypothesis. Rather, larvae in a given tundra pond appear to develop synchronously throughout the life cycle, including a period of substantial growth and rapid prepupal development between spring thaw and early-summer emergence.
Short and Medium Latency Responses in Participants With Chronic Ankle Instability
Authors: Sousa Andreia S. P. , Valente Isabel , Pinto Ana , Soutelo Tiago , Silva Márcia
Published: August 2018

Context: 

The determinant role of medium latency responses (MLRs) during compensatory postural adjustments in postural stability and the lack of clarity about the mechanisms behind chronic ankle instability (CAI) sustain the hypothesis that these postural responses are impaired in this condition. However, to the best of our knowledge, no authors have assessed MLRs in patients with CAI; most of the research regarding compensatory postural adjustments has been directed at the timing of short latency responses (SLRs).

Objective: 

To evaluate bilateral compensatory postural responses, including SLRs and MLRs, in response to a unilateral simulated ankle-sprain mechanism in participants with CAI.

Design: 

Case-control study.

Setting: 

Laboratory.

Patients or Other Participants: 

Twenty-four participants with CAI and 20 controls.

Intervention(s): 

Bilateral electromyography of the peroneus longus (PL), peroneus brevis, tibialis anterior (TA), and soleus (SOL) muscles was collected during a unilateral sudden-inversion perturbation (30°).

Main Outcome Measure(s): 

Muscle-onset activations and magnitudes of SLRs and MLRs in the support and perturbed positions.

Results: 

Participants with CAI showed (1) later-onset activation of the TA and SOL in the uninjured limb and bilateral decreases in the magnitude of the TA MLR in the support position, (2) increased magnitude of the PL MLR in the uninjured limb in the support and perturbed positions, and (3) increased magnitude of the PL SLR and MLR in the injured limb in the perturbed position.

Conclusions: 

Chronic ankle instability was associated with later TA and SOL activation in the uninjured limb and bilaterally decreased magnitude of the TA MLR in the support position.
The Lived Experiences of Retired Collegiate Athletes With a History of 1 or More Concussions
Authors: Cover Rebecca , Roiger Trevor , Zwart Mary Beth
Published: August 2018

Context: 

Concussions remain misunderstood, underreported, and undiagnosed. Although most concussion symptoms resolve within 2 weeks, some patients experience persistent symptoms that adversely affect physical, emotional, social, or cognitive functioning or a combination of these. Minimal evidence delineating the effect of concussions on recently retired collegiate athletes currently exists.

Objective: 

To examine the lived experiences of retired collegiate athletes with a history of 1 or more concussions to discern individual concussion histories, knowledge and perceptions of concussions, and postconcussion quality of life.

Design: 

Qualitative study.

Setting: 

Telephone interviews.

Patients or Other Participants: 

Former National Collegiate Athletic Association Division I athletes (n = 14) with a history of 1 or more concussions and retired from 1 to 5 years.

Data Collection and Analysis: 

Fourteen semistructured telephone interviews (8 men and 6 women) were audiotaped. Interviews were transcribed and inductively analyzed by 3 athletic trainers with 34 combined years of professional experience. Themes were negotiated through consensual review. Participant checks were completed to ensure trustworthiness of the findings.

Results: 

Participants sustained their first concussion during adolescence and often experienced difficulties transitioning back into the postconcussion academic environment. Judgments of injury severity were clearly evident in participants' knowledge and perceptions of concussions. Participants experienced an array of emotional, physical, cognitive, and social challenges during the immediate postconcussion period but did not feel their concussion history decreased their current quality of life.

Conclusions: 

Adolescent exposure to concussions is of concern due to the risk imposed on the developing brain and the potential for adverse outcomes later in life. Although a graduated return to play is heavily emphasized in concussion management, researchers need to investigate barriers inhibiting the implementation of return-to-learn protocols. Concussion education should aim to modify indifferent attitudes toward concussive injuries. Additionally, investigators should continue to assess how a history of concussion affects quality of life in recently retired collegiate athletes.
The Use of Patient-Reported Outcome Measures: Secondary School Athletic Trainers' Perceptions, Practices, and Barriers
Authors: Coulombe Brian J. , Games Kenneth E. , Eberman Lindsey E.
Published: August 2018

Context

Incorporating patient-reported outcomes (PROs) into daily routine is essential for patient-centered clinical practice. Secondary school athletic trainers (ATs) may encounter unique barriers that limit their willingness to use PROs.

Objective

To explore how secondary school ATs who were using PROs perceived their application, benefits, and problems compared with those who did not.

Design

Cross-sectional study.

Setting

Web-based survey.

Patients or Other Participants

A total of 2984 secondary school ATs received an e-mail invitation, and 322 completed the survey (response rate = 10.8%). Respondents were 43 ± 10 years old, with most indicating at least 11 years as a Board of Certification–certified AT (n = 276, 85.7%).

Main Outcome Measure(s)

The ATs were invited to complete a Web-based survey regarding the uses and benefits of and problems with PROs. Those using PROs in clinical practice were asked their criteria for selecting the measures, whereas those not using PROs were asked their reasons for not using them. Dependent variables were endorsements of uses and benefits of and problems with PROs.

Results

The most commonly cited uses of PROs were determining treatment effectiveness (193/264, 73%) and demonstrating effectiveness to administration (174/264, 66%). Improving communication with the patient (267/296, 90%) and helping to direct the plan of care (256/297, 86%) were the most frequently endorsed benefits of PROs. Time to score and analyze (152/284, 53%) and time for patients to complete (134/284, 47%) PROs were the problems encountered most often. For ATs not using PROs (223/262, 85%), the most frequent reason was the lack of a support structure (102/219, 46%). For ATs using PROs (39/262, 15%), quick completion times (32/39, 82%) was the most common criterion used to select individual measures.

Conclusions

A majority of secondary school ATs recognized the benefits of PROs and yet did not use them in clinical practice due to setting-specific barriers.
Prophetic preaching in the socio-economic and socio-political crisis of Zimbabwe
Authors: Fenga Vincent F. , Wepener Cas
Published: August 2018

In Zimbabwe, there are different preachers who have great names, but when it comes to prophetic preaching they lag behind as compared to South Africa, which has great preachers in prophetic preaching like Desmond Tutu. In this era, however, we are challenged with a situation of socio-economic and socio-political crisis: the enormous poverty among approximately 95% of the population. This article discusses the circumstances for prophetic preaching in the contemporary context of Zimbabwe, which are a clear understanding of the poverty position and cohesion of the church with the poor, a good understanding of the image of prophetic preaching as a specific type of preaching that encompasses the four elements of preaching: the preacher, as well as the congregation (hearers), the sermon and the Holy Spirit for prophetic preaching.Interdisciplinary and intradisciplinary implications: This article discusses the circumstances for prophetic preaching in the context of Zimbabwe, which are a clear understanding of the poverty position and cohesion of the church with the poor. In our analysis of prophetic preaching in Zimbabwe, the emphasis is put on prophecy, healing, deliverance and prosperity. This article argues that prophetic preaching is approaching the biblical text with a view to interpret it as preaching in a context of poverty. It should be done from the perspective of the poor, therefore in terms of their need for justice and righteousness.
Use of Web 2.0 Tools by National Youth Service Corps (NYSC) members for social integration: a case of Lapai Local Government Area (LGA) of Niger State
Authors: Solomon Anthony O. , Obaseki Tony I.
Published: August 2018

The research work x-rayed the use of Web 2.0 tools by Corps members in Lapai LGA of Niger State. The study adopted a descriptive survey research design. Questionnaire was used to elicit responses from the respondents. A sample size of 120 was drawn from a population of 138, using the random sampling technique. Of the 120 copies of the questionnaire administered, 108 copies were retrieved and used for analysis. The research findings show that the commonly used Web 2.0 tools by Corps members in Lapai LGA are Facebook, WhatsApp, Instagram, YouTube, Twitter, Podcasts, LinkedIn, IMO and Skype. The respondents used Web 2.0 tools frequently, and the purposes for which the tools are used include social interactions, live video chats, for economic activities, etc. The study showed that web 2.0 tools are useful because of their ‘easy to use’, ‘interactivity’, ‘social collaborative features’ and ‘updated in real-time’. Further revelations from the study showed constraints militating against the use of Web 2.0 tools include are high cost of data subscription, poor network signals and connectivity, addiction, high cost of support facilities and gadgets. The study however recommends that youths should explore Web 2.0 tools for academic and economic purposes while network providers and government should make the cyberspace affordable and safe.Keywords: Web 2.0, Corps members, Lapai LGA, Niger State, Youths

Published: August 2018

Universities are working in a very dynamic and powerfully viable environment today. Due to the advent of information technology, they gather large volumes of data related to their students in electronic form in various formats like records, files, documents, images, sound, videos, scientific data and many new data formats. This study focuses on predicting performance of student at an early stage of the degree program, in order to help the university not only to focus more on bright students but also to initially identify students with low academic achievement and find ways to support them. The knowledge is hidden among the educational data set and it is extractable through data mining techniques. The aim of this paper is to use data mining methodologies to design and develop a Data Mining model to predict academic performance of students at the end of first year degree program in selected Ethiopian higher educational institutions (universities).The data of different undergraduate students has been mined with decision tree classifiers. A model is built using C4.5 Decision tree learning algorithm – generates five classification rule set classifiers (predictors) in an experiment. The experiment using a test data set produces 81.4% accuracy.Keywords: Educational Data, Educational Data mining, Decision tree, Classification rule, C4.5

Authors: Fagundez D'Anello Daniel A.
Published: August 2018

Las transformaciones urbanas pueden afectar el problema de las personas en situación de calle. El objetivo de este estudio fue comprender, desde la perspectiva de la Teoría de Actor Red, cómo es que las transformaciones de los ensamblajes urbanos de la ciudad de Montevideo actúan sobre el problema de la adolescencia en situación de calle. Mediante un estudio etnográfico se analizaron las relaciones entre estos adolescentes, los operadores sociales, los diseñadores de las políticas y las entidades no humanas implicadas en la producción del problema. La etnografía se llevó a cabo entre los años 2013 y 2016, junto a un programa de intervención en la calle y en su establecimiento de trabajo, sumado al análisis documental oficial del problema en Uruguay. El análisis fue realizado desde los estudios de la teoría del actor-red y la teoría de los ensamblajes urbanos. Los resultados indican que los cambios urbanos en el territorio de intervención de este equipo, fueron determinantes para comprender la transformación del problema de la situación de calle extrema de los adolescentes. También se visualizó que los operadores sociales son informantes claves para dar cuenta de cómo se producen estos cambios. Se discuten estos resultados con estudios de diversas partes del mundo, incluyendo de forma novedosa el análisis desde el concepto de los ensamblajes urbanos y la teoría del actor red.
What role do children play in social services?
Authors: Montserrat Carme , Casas Ferran
Published: August 2018

Greater emphasis is being placed on developing policies that provide services based on the user's perspective and this includes the perspective of children's rights. This study analyses professional practices in interventions involving children and families at 40 Social Services Centres in Barcelona with a view to identifying the degree of child participation. Taking into account the perspective of the different stakeholders, i.e., practitioners as providers and children and families as users, we implemented a mixed methodological research design: data analysis from the city council database (N=56,468); quantitative data collection based on a questionnaire directed to practitioners (N=225); qualitative data collection based on interviews with adults and children (N=39); focus groups made up of practitioners (N=30), and user satisfaction surveys directed to adults (N=280) and children (N=120). We use triangulation for data analysis. Results indicated low child participation, lack of clarity regarding work methods and professional profiles, and problems in evaluating outcomes. Perceptions differed greatly depending on the sources consulted, and this could have implications for policy and practice.

The relative impact of cloud condensation nuclei
and ice nucleating particle concentrations on phase-partitioning in Arctic Mixed-Phase Stratocumulus Clouds
Authors: Solomon Amy , de Boer Gijs , Creamean Jessie M. , McComiskey Allison , Shupe Matthew D. , Maahn Maximilian , Cox Christopher
Published: August 2018

Abstract. This study investigates the interactions between cloud dynamics and aerosols in idealized large-eddy simulations of an Arctic mixed-phase stratocumulus cloud observed at Oliktok Point, Alaska in April 2015. This case was chosen because it allows the cloud to form in response to radiative cooling starting from a cloud-free state, rather than requiring the cloud ice and liquid to adjust to an initial cloudy state. Sensitivity studies are used to identify whether there are buffering feedbacks that limit the impact of aerosol perturbations. The results of this study indicate that perturbations in ice nucleating particles (INPs) dominate over cloud condensation nuclei (CCN) perturbations, i.e., an equivalent fractional decrease in CCN and INPs results in an increase in the cloud-top longwave cooling rate, even though the droplet effective radius increases and the cloud emissivity decreases. The dominant effect of ice in the simulated mixed-phase cloud is a thinning rather than a glaciation, causing the mixed-phase clouds to radiate as a grey body and the radiative properties of the cloud to be more sensitive to aerosol perturbations. It is demonstrated that allowing prognostic CCN and INP causes a layering of the aerosols, with increased concentrations of CCN above cloud top and increased concentrations of INP at the base of the cloud-driven mixed-layer. This layering contributes to the maintenance of the cloud liquid, which drives the dynamics of the cloud system.
Digital map of the Coral Triangle: An online atlas for marine biodiversity conservation
Authors: Asaad Irawan , Lundquist Carolyn J. , Erdmann Mark V. , Costello Mark J.
Published: August 2018

Abstract. An online atlas of the Coral Triangle region of the Indo Pacific biogeographic realm was developed. This online atlas consists of the three interlinked digital maps: (1) Biodiversity Features; (2) Areas of Importance for Biodiversity Conservation; (3) Recommended Priorities for Marine Protected Area (MPA) Network Expansion (www.marine.auckland.ac.nz/CTMAPS). The first map, Biodiversity Features, provides comprehensive data on the region's marine protected areas and biodiversity features, threats and environmental characteristics. The second provides spatial information on areas of high biodiversity conservation values, while the third map shows priority areas for expanding the current Coral Triangle MPA network. This digital map provides the most comprehensive biodiversity datasets yet assembled for the region. The datasets were retrieved and generated systematically from various open-access sources. To engage a wider audience and to raise participation in biodiversity conservation, the maps were designed as an interactive and online atlas. This digital map presents representative information to promote a better understanding of the key marine and coastal biodiversity characteristics of the region and enables the application of marine biodiversity informatics to support marine ecosystem-based management in the Coral Triangle region.
Sensitivity of deep ocean biases to horizontal resolution in prototype CMIP6 simulations with AWI-CM1.0
Authors: Rackow Thomas , Sein Dmitry , Semmler Tido , Danilov Sergey , Koldunov Nikolay , Sidorenko Dmitry , Wang Qiang , Jung Thomas
Published: August 2018

Abstract. CMIP5 models show substantial biases in the deep ocean that are larger than the level of natural variability and the response to enhanced greenhouse gas concentrations. Here we analyse the influence of horizontal resolution in a hierarchy of five multi-resolution simulations with the AWI Climate Model (AWI-CM), which employs a sea ice-ocean model component formulated on unstructured meshes. The ocean grid sizes considered range from a nominal resolution of ∼1° (CMIP5-type) up to locally eddy-resolving. We show that increasing ocean resolution locally to resolve ocean eddies leads to a major reduction in deep ocean biases. A detailed diagnosis of the simulations allows to identify the origins of the biases. We find that two major sources at the surface are responsible for the deep bias in the Atlantic Ocean. Furthermore, the Southern Ocean density structure is equally improved with locally explicitly resolved eddies compared to parameterized eddies. Part of the bias reduction can be traced back towards improved surface biases over outcropping regions, which are in contact with deeper ocean layers along isopycnal surfaces. Our prototype simulations provide guidance for the optimal choice of ocean grids for AWI-CM to be used in the final runs for phase 6 of the 'Coupled Model Intercomparison Project' (CMIP6) and for the related flagship simulations in the 'High Resolution Model Intercomparison Project' (HighResMIP). Quite remarkably, retaining resolution only in areas of high eddy activity along with excellent scalability characteristics of the unstructured-mesh sea ice-ocean model enables us to perform the multi-centennial climate simulations needed in a CMIP context at (locally) eddy-resolving resolution with a throughput of 5–6 simulated years per day.
A Mixed Methods Study of Leaders’ Perceptions of Microlearning for Professional Development on the Job
Authors: Hanshaw George , Hanson Janet
Published: August 2018

This study investigated the use of mobile microlearning, supported with social learning strategies, and its perceived usefulness as a delivery mode for professional development on the job. The use of computer-mediated communication and microlearning have been explored in educational settings. This study expanded the context to managers and leaders in the aerospace industry (n=15) and healthcare professions (n=20). Data was collected using a self-developed, semi-structured interview protocol and Likert-style survey. A professional development training, using the Graphical Inventory of Ethical Leadership (GIEL) survey tool, was delivered to participants’ mobile devices. Six themes emerged from the inductive analyses of the participants’ responses including: the flexible delivery saves time, maintains leader’s presence on the job, builds team cohesiveness, meets the leaders’ needs for personalizing delivery of the PD/understanding their employees’ learning needs, provides individuals with a voice in the selection of learning opportunities, and the absence of participants’ stated concerns over the use of technology. Conclusions, models for understanding the concepts, and implications for practice are provided.
Blind Median Filtering Detection Using Auto-Regressive Model and Markov Chain
Authors: Peng Anjie , Yu Gao , Zeng Hui
Published: August 2018

Establishing the processing history of an image is important for robot vision. In this paper, an improved method for median filtering detection is proposed. That is, detect whether an image has been processed by median filtering. First, we analyze the statistical properties of median filtering residual and find that it is suitable for exposing fingerprints of median filtering. Then, the new feature set on median filtering residual is constructed by incorporating transition probability matrices of Markov chain with coefficients of auto-regressive model. A dimensionality reduction method is developed to lower the feature dimensionality. The final feature set is fed into support vector machines to construct a detector. Due to the distinction property of median filtering residual as well as compensated effect between transition probability and auto-regressive model, experimental results on large image database demonstrate that the proposed method is effectively in median filtering detection, even for images with heavy JPEG compression or at a low resolution. The performance of proposed detector outperforms prior arts. Additionally, the proposed method demonstrates good generalization ability.
Knee Pain After Intramedullary Nailing of Tibia Fractures: Prevalence, Etiology, and Treatment
Authors: Bishop Julius A. , Campbell Sean T. , Eno Jonathan-James T. , Gardner Michael J.
Published: August 2018

Intramedullary nailing is often the treatment of choice for fractures of the tibia, but postoperative knee pain is common after this procedure. Potential etiologies include implant prominence, injury to intra-articular structures, patellar tendon or fat pad injury, damage to the infrapatellar branch of the saphenous nerve, and altered biomechanics. Depending on the etiology, described treatment options include observation, implant removal, assessment and treatment of injured intra-articular structures, and selective denervation. Careful attention to appropriate starting point and implant selection combined with more recently described semiextended nailing techniques may aid in prevention of knee pain.
Banks and Fintechs: How to Develop a Digital Open Banking Approach for the Bank’s Future
Authors: Omarini Anna Eugenia
Published: August 2018

Mutated market conditions, the advent of new players and digital technologies, and a significant regulatory push, are profoundly changing the banking industry. Banking business models may shift significantly from a pipeline, vertical, paradigm, to open banking models where modularity can be an opportunity for banks. Not only are the abovementioned factors representing a threat to the traditional model, but also they are spurring significant new opportunities to pursue new revenue streams. Those opportunities are exploited through new banking paradigms that entail higher levels of openness towards third parties and a crescent number of modular services bundled together. Models can go to mere compliance with the prescriptions of openness of PSD2, to the inclusion of new services, the opening of the banking core and data, and the aggregation of those within a platform experience. Value is created in platforms through economies of scope in production and innovation.This paper has explored the evolution of Fintech and Techfin in the market and the emergence of platform models in banking. It has investigated the evolution of that concept, also introducing an interesting banking case (BBVA), which gives several insights on the choices made toward a Banking-as-a-Platform model within the context of Fintech and Open Banking.
The Icons of Military Saints in Rus’. An Attempt at Classifying Iconographic Types from before the Beginning of the 17th Century

Depictions of military martyrs were among the most popular subjects in icon painting in Rus’. Between the 11th and the 17th century local workshops adopted canonical Byzantine models and gradually developed and changed them depending on local factors and conditions. The present article attempts to classify the most common iconographic types and to describe the dynamic of the changes in the iconographic canon on the basis of a  qualitative and quantitative analysis of extant and known works.
Combining Limited Liability and Transparent Taxation: Lessons From the Convergent Evolution of GmbH & Co. KGs, S Corporations, LLCs, and Other Functionally Equivalent Entities
Authors: Röder Erik
Published: August 2018

Tax transparent limited liability entities (TTLLEs), such as the GmbH & Co. KG in Germany, the trading trust in Australia, or the S Corporation and the LLC in the United States, can be found in many developed economies. While these entities are to a large extent functionally equivalent, their underlying legal mechanics are very different. The Article traces the convergent evolution of six TTLLEs in five jurisdictions, along three different paths, and describes central determinants of path dependencies. It demonstrates that the demand for TTLLEs is universal and that their availability reduces distortions caused by a traditional tax system. Furthermore, the Article argues that the often reviled distortive influence of tax law on the choice of business entity, which drove the evolution of TTLLEs, sparked innovations in the law of business organizations that would probably not have occurred otherwise, or only much later. Finally, the Article recommends making transparent taxation and entity taxation optionally available to all types of business entities and suggests carefully rationalizing the organizational law of TTLLEs while maintaining the diversity of forms that has evolved.
From the Critique of Reason to a Critique of Culture
Authors: Truwant Simon ,   Philosophy Documentation Center
Published: August 2018

This paper argues that Cassirer’s development of ‘the critique of reason into a critique of culture’ was prompted by two motives that ultimately seem to collide. On the one hand, Cassirer attempts to overcome the Kantian dichotomy between the faculties of sensibility and the understanding. To this end, he turns to the schemata of the Critique of Judgment. On the other hand, Cassirer expands the scope of transcendental philosophy to include cultural domains such as myth, language, and the human sciences. His desire to maintain both the differences between these domains and the unity of reason however leads to a new dualism between the material modalities of the symbols and their ideal, recurring, forms. Yet, by adopting both a constitutive and a regulative conception of objectivity, Cassirer renders this duality legitimate, and his motives for a philosophy of culture on a Kantian foundation compatible.
The Resistant Interlocutor
Authors: Davies Katherine ,   Philosophy Documentation Center
Published: August 2018

Dialogue, as a philosophical form, enables the exploration of the conditions, limits, and consequences of understanding arguments. Two philosophers who undertook to write dialogues—Plato and Heidegger—feature moments in philosophical conversation in which understanding, on its own, fails to convince an interlocutor of an argument. In this article, I examine the philosophical stakes of the collisions which unfold in Plato’s Gorgias, between Socrates and Callicles, and in Heidegger’s “Triadic Conversation,” between the Guide and the Scientist. Plato’s Socrates is ostensibly unsuccessful in persuading Callicles to adopt his position while Heidegger’s Guide is able to support the Scientist in learning a new way of thinking. I argue that it is Heidegger’s attention to feeling as a philosophically significant phenomenon which can overcome trans-rational resistance which may persist even after truth has been determined.
A construção de si mesma: a presença da figura de Kiki de Montparnasse no cenário vanguardista
Authors:   Universidade Federal do Rio Grande do Sul, Alvarez Anelise Valls
Published: August 2018

O escopo deste artigo consiste em traçar alguns pontos da construção da figura de Alice Prin - mais conhecida como Kiki de Montparnasse – em relação os reconhecidos artistas homens modernistas durante o período do entre-guerras, bem como a construção-invenção de si mesmaobservada no conjunto da produção artística de Kiki. Neste sentido, buscamos por um lado, compreender a ambiência deste mundo que a retratou e, por outro, para efeito de contraposição a este contexto, nos detemos na participação feminina peculiar de Kiki e os escritos de seu diário.
Vox et Facies para o retrato

Published: August 2018

Alguns aspéctos do retrato, genêro presente em mais de um dos mitos da pintura, são abordados aqui, tais como: a origem da palavra ligada ao termo latino retrahere; suas possíveis relações com a noção de "fala", ou de "voz"; sua capacidade de expressão de um em si do sujeito. A natureza serial que o retrato assume nos trabalhos de artistas como Gerhard Richter e Christian Boltanski é trazida à tona ao lado de textos de Walter Benjamin e Jean Luc Nancy que avaliam a natureza singular do retrato assim como da fala humana. Por fim, um ensaio visual composto por trabalhos da série os dias, de nossa autoria, investiga o funcionamento do retrato no seio da problemática entre a palavra e a imagem.
Nuevos usos espaciales en las estaciones ferroviarias de alta velocidad/New space use of high speed railway stations
Authors: Soria Caceres Carlos Hugo
Published: August 2018

RESUMENLas infraestructuras de transporte presentes sobre el territorio condicionan las relaciones sociales y de comunicación de muchos espacios. Grandes estaciones, puertos o aeropuertos se presentan como ejes de centralidad sobre los que se distribuyen flujos de mercancías y personas, configurando a su vez el diseño y la funcionalidad de las ciudades. Hoy en día, con el avance producido en sectores como el ferrocarril de alta velocidad, las estaciones han transformado su función principal de nudo de intercambio, proyectándose como nuevos espacios comerciales y de negocio. En este artículo se analiza este nuevo fenómeno de transformación espacial y social vinculado a la alta velocidad ferroviaria, focalizando su ámbito en España. Se desgrana a su vez el papel de las comunidades sociales, políticas y empresariales para la ciudad y el espacio público presentes en las nuevas estaciones de ferroviarias. Palabras clave: ferrocarril; espacio público; urbanismo. ABSTRACTThis work aims to discuss the transport infrastructures presents on the territory and the conditions to the social and communication relations of many spaces. Large stations, ports or airports are presented as axes of centrality on which flows of goods and people are distributed, configuring in turn the design and functionality of cities. Nowadays, with the advance produced in sectors such as high-speed rail, the stations have transformed their main function as an exchange hub, projecting themselves as new commercial and business spaces. This article analyzes this new phenomenon of spatial and social transformation linked to high-speed rail, focusing its scope in Spain. At the same time, the role of the social, political and business communities for the city and the public space present in the new railway stations.Keywords: railroad; public space; urbanism.
Automated Creation and Provisioning of Decision Information Packages for the Smart Factory

Published: August 2018

In recent years, Industry 4.0 emerges as a new trend, enabling the integration of data-intensive cyber physical systems, Internet of Things, and mobile applications, into production environments. Even though Industry 4.0 concentrates on automated engineering and manufacturing processing, the human actor is still important for decision making in the product lifecycle process. To support correct and efficient decision making, human actors have to be provided with relevant data depending on the current context. This data needs to be retrieved from distributed sources like bill of material systems, product data management and manufacturing execution systems, holding product model and factory model. In this article, we address this issue by introducing the concept of decision information packages, which enable to compose relevant engineering data for a specific context from distributed data sources. To determine relevant data, we specify a context-aware engineering data model and corresponding operators. To realize our approach, we provide an architecture and a prototypical implementation based on requirements of a real case scenario. This article is a revised and selected version of the previous work.
Estimating the protein burden limit of yeast cells by measuring the expression limits of glycolytic proteins

The ultimate overexpression of a protein could cause growth defects, which are known as the protein burden. However, the expression limit at which the protein-burden effect is triggered is still unclear. To estimate this limit, we systematically measured the overexpression limits of glycolytic proteins in Saccharomyces cerevisiae. The limits of some glycolytic proteins were up to 15% of the total cellular protein. These limits were independent of the proteins’ catalytic activities, a finding that was supported by an in silico analysis. Some proteins had low expression limits that were explained by their localization and metabolic perturbations. The codon usage should be highly optimized to trigger the protein-burden effect, even under strong transcriptional induction. The S–S-bond-connected aggregation mediated by the cysteine residues of a protein might affect its expression limit. Theoretically, only non-harmful proteins could be expressed up to the protein-burden limit. Therefore, we established a framework to distinguish proteins that are harmful and non-harmful upon overexpression.
Self-report questionnaires, behavioral assessment tasks, and an implicit behavior measure: do they predict social anxiety in everyday life?

Social anxiety is commonly assessed with self-report measures. This study aimed to investigate whether maximum anxiety levels during in vivo and virtual reality behavioral assessment tasks (BATs), and implicit approach-avoidance tendencies during the approach-avoidance task (AAT) explain more variation as predictors of daily social anxiety than self-report measures. A total of 62 university students (Mage = 20.79; SD = 4.91) with high levels of social anxiety completed self-report measures on fear of negative evaluation (FNE-B) as well as fear and avoidance in social situations (Liebowitz social anxiety scale-self report), in vivo and virtual reality BATs, and the AAT (independent variables) in the laboratory. On seven consecutive days, social anxiety, experiential avoidance, and negative social events (dependent variables) were assessed. The results revealed that fear of negative evaluation predicted everyday social anxiety and experiential avoidance. Fear and avoidance in social situations only predicted experiential avoidance. Neither implicit approach-avoidance tendencies during the AAT nor maximum anxiety levels during the in vivo and virtual reality BATs predicted any outcome variable. Our results support the use of self-report questionnaires in the assessment of social anxiety.

Исследованы ЭПР-спектры фторгафнатных стекол типа ZBLAN на примере состава 58HfF4 · 20BaF2 · · 2LaF3 · 3AlF3 · 17NaF, активированных европием и гадолинием. Впервые количественно оценивалось отношение концентрации свободных ионов Eu2+ и Gd3+ к их концентрации в кластерах. Обнаружено, что с уменьшением концентрации активаторов доля свободных ионов существенно возрастает. При концентрациях 1.25 мол. % EuF2 и 1 мол. % GdF3 ионы активаторов в основном находятся в кластерных образованиях и лишь малая часть в виде индивидуальных ионов, тогда как при 0.1 мол. % EuF2 концентрации свободных и кластерных ионов сопоставимы.
КЕРАМИКА НА ОСНОВЕ ПОРОШКОВЫХ СМЕСЕЙ, СОДЕРЖАЩИХ ГИДРОФОСФАТЫ КАЛЬЦИЯ И СОЛИ НАТРИЯ (NA2CO3, NA4P2O7, NAPO3), "Неорганические материалы"

Керамику в системе Na2O-CaO-P2O5 получали из порошковых смесей, включающих гидрофосфаты кальция (монетит/брушит, CaHPO4/CaHPO4.2H2O) и соли натрия (Na2CO3.Н2О, Na4P2O7.10Н2О, NaPO3). Указанные соли были взяты в качестве прекурсоров следующих высокотемпературных фаз: Сa2P2O7, Na2O, Na4P2O7, NaPO3. Количество добавок солей в порошковой смеси было рассчитано таким образом, чтобы оксидный состав керамики соответствовал 10 мол.% оксида натрия для каждой смеси в системе Na2O-CaO-P2O5. Порошковые смеси готовили с использованием механической активации в ацетоне, при проведении которой наблюдали явление регидратации монетита до брушита. По данным РФА, после обжига фазовый состав керамики из подготовленных порошковых смесей принадлежал области Сa2P2O7-NaCaPO4-Na2СaP2O7-Са(РО3)2. Полученные керамические материалы включают биосовместимые резорбируемые фазы и могут быть рекомендованы для изготовления костных имплантатов.
