The Copyright Book
Authors: Strong William S. 
Published: March 2019

An accessible and comprehensive guide to copyright law, updated to include new developments in infringement, fair use, and the impact of digital technology.
Through five editions since 1981, this book has offered the most comprehensive accessible guide available to all aspects of copyright law. Now, with the sixth edition, The Copyright Book has been thoroughly updated to cover copyright for the Internet age, discussing a range of developments in the law since 2000. The only book written for nonlawyers that covers the entire field of copyright law, it is essential reading for authors, artists, creative people in every medium, the companies that hire them, users of copyrighted material, and anyone with an interest in copyright law from a policy perspective.
New material includes greatly expanded coverage of infringement and fair use, with detailed discussion of recent decisions, including the Grateful Dead, Google, and HathiTrust cases. The new edition considers such topics as open access, the defeat of the Stop Online Piracy Act (SOPA), file sharing, e-reserves, the status of “orphan works,” and the latest developments under the Digital Millennium Copyright Act (DMCA).

The sixth edition also brings up to date The Copyright Book's plain English explanation of such fundamental topics as authorship and ownership; transfers and licenses of copyright; copyright notice; registration of copyright (including the new online registration and “preregistration” systems); the scope of rights included in copyright, and exceptions to those rights; “moral rights”; compulsory licenses; tax treatment of copyright; and international aspects of copyright law.
As copyright issues grow ever more complicated, The Copyright Book becomes ever more indispensable.
Coding Places
Authors: Takhteyev Yuri 
Published: March 2019

An examination of software practice in Brazil that reveals both the globalization and the localization of software development.
Software development would seem to be a quintessential example of today's Internet-enabled “knowledge work”—a global profession not bound by the constraints of geography. In Coding Places, Yuri Takhteyev looks at the work of software developers who inhabit two contexts: a geographical area—in this case, greater Rio de Janeiro—and a “world of practice,” a global system of activities linked by shared meanings and joint practice. The work of the Brazilian developers, Takhteyev discovers, reveals a paradox of the world of software: it is both diffuse and sharply centralized. The world of software revolves around a handful of places—in particular, the San Francisco Bay area—that exercise substantial control over both the material and cultural elements of software production. Takhteyev shows how in this context Brazilian software developers work to find their place in the world of software and to bring its benefits to their city.
Takhteyev's study closely examines Lua, an open source programming language developed in Rio but used in such internationally popular products as World of Warcraft and Angry Birds. He shows that Lua had to be separated from its local origins on the periphery in order to achieve success abroad. The developers, Portuguese speakers, used English in much of their work on Lua. By bringing to light the work that peripheral practitioners must do to give software its seeming universality, Takhteyev offers a revealing perspective on the not-so-flat world of globalization.
Logic in Games
Authors: van Benthem Johan , Velazquez Quesada Fernando R. 
Published: March 2019

A comprehensive examination of the interfaces of logic, computer science, and game theory, drawing on twenty years of research on logic and games.
This book draws on ideas from philosophical logic, computational logic, multi-agent systems, and game theory to offer a comprehensive account of logic and games viewed in two complementary ways. It examines the logic of games: the development of sophisticated modern dynamic logics that model information flow, communication, and interactive structures in games. It also examines logic as games: the idea that logical activities of reasoning and many related tasks can be viewed in the form of games.
In doing so, the book takes up the “intelligent interaction” of agents engaging in competitive or cooperative activities and examines the patterns of strategic behavior that arise. It develops modern logical systems that can analyze information-driven changes in players' knowledge and beliefs, and introduces the “Theory of Play” that emerges from the combination of logic and game theory. This results in a new view of logic itself as an interactive rational activity based on reasoning, perception, and communication that has particular relevance for games.
Logic in Games, based on a course taught by the author at Stanford University, the University of Amsterdam, and elsewhere, can be used in advanced seminars and as a resource for researchers.

Connected Code
Authors: Kafai Yasmin B. , Burke Quinn 
Published: March 2019

Why every child needs to learn to code: the shift from “computational thinking” to computational participation.
Coding, once considered an arcane craft practiced by solitary techies, is now recognized by educators and theorists as a crucial skill, even a new literacy, for all children. Programming is often promoted in K-12 schools as a way to encourage “computational thinking”—which has now become the umbrella term for understanding what computer science has to contribute to reasoning and communicating in an ever-increasingly digital world.
In Connected Code, Yasmin Kafai and Quinn Burke argue that although computational thinking represents an excellent starting point, the broader conception of “computational participation” better captures the twenty-first-century reality. Computational participation moves beyond the individual to focus on wider social networks and a DIY culture of digital “making.”
Kafai and Burke describe contemporary examples of computational participation: students who code not for the sake of coding but to create games, stories, and animations to share; the emergence of youth programming communities; the practices and ethical challenges of remixing (rather than starting from scratch); and the move beyond stationary screens to programmable toys, tools, and textiles.
Up-regulation of Grb2-associated binder 1 promotes hepatocyte growth factor-induced endothelial progenitor cell proliferation and migration
Authors: Fan Qing , Zhang Liyu , Zhu Wenjie , Xue Sheng , Song Yisheng , Chang Qing 
Published: March 2019

Objectives
Grb2-associated binder 1 (Gab1), a scaffolding adaptor protein, plays an important role in transmitting key signals that control cell growth, migration, and function from multiple tyrosine kinase receptors. This study was designed to investigate the influence of upregulation of Gab1 in endothelial progenitor cells (EPCs) stimulated with hepatocyte growth factor (HGF), and the underlying molecular mechanisms.

Materials and Methods
Endothelial progenitor cells isolated from human umbilical cord blood were identified and divided into four groups. EPCs in the Control group were cultured normally; those in the Control+HGF group were treated with HGF stimulation; those in the AD-Gab1 group were transfected with adenovirus containing the Gab1 gene but not treated with HGF stimulation; and, those in the AD-Gab1+HGF group were treated with both HGF stimulation and transfection with adenovirus containing the Gab1 gene. Subsequently, Gab1 expression and proliferation and migration ability were compared for EPCs grown under different conditions. Furthermore, we measured phosphorylation levels of three key proteins Gab1, SHP2, and ERK1/2.

Results
The AD-Gab1+HGF group had the highest expression of Gab1 and higher proliferation and migration than the other three groups.

Conclusions
Upregulation of Gab1 promoted HGF-induced EPC proliferation and migration. Mechanistically, HGF stimulated Gab1 tyrosine phosphorylation in EPCs, thus leading to activation of extracellular regulated MAP kinase 1/2, which is involved in proliferation and migration signaling.
Influence of Environmental Knowledge on Small Scale Women Farmers Adoption of Conservation Agriculture Nakuru County, Kenya
Authors: Michura Eliud Garry , Michura Anne Jerotich 
Published: March 2019

Adoption of any technology especially in agricultural practices depends on environmental dynamics. This paper evaluated the influence of environmental knowledge on women small-scale farmers on adoption of conservation agriculture (CA) in Nakuru County. Kenya as one of the developing countries in Africa faced with numerous problems particularly food insecurity, hunger, poverty, diseases and biodiversity loss as a result of conventional agriculture practiced under poor backdrop of environmental knowledge. To alleviate all these problems mentioned above, the alternative method of agricultural practice should now aim at improving conservation agriculture which was discouraged long time ago. But environmental Knowledge to adopt conservation agriculture is needed as better option for maximum agricultural yields and protection of the environment. It is claimed that, CA adoption in Nakuru County by women small-scale farmers was low and there was inadequate research documentation regarding this claim. To establish the claim whether true or not, find out why CA adoption was low in the study area, the research sampled three sites; Naivasha, Rongai and Njoro selected purposefully for differences in ecological characteristics. The sample size of 360 women farmers were randomly selected from a target population of 120,000 women farmers of which, 120 were selected from each of three Sub Counties. Descriptive survey design using structured questionnaires; interview schedule, personal observation and focus group discussion were used to collect data. Statistical package for social sciences (SPSS version 20) was used in the data processing and analysis. Descriptive statistics; frequency distributions, means, proportions, percentages and inferential statistics; Chi-square, ANOVA, Bonferroni test at alpha value (p < 0.05) level were employed to test the hypothesis. The findings concluded that knowledge of the environment influenced women small scale farmers’ adoption of CA and that CA adoption uptake was low. Recommendations; Policy and decision makers use the results to develop land and agricultural policies, provide incentives to promote small-scale women farmers, use new emerging technologies to speed up knowledge on adoption of CA in order to boost food security and conservation of the environment in Nakuru County and Kenya.

The hypersurface yn–1 in yn space is studied for this piece of work. We established the correlation between tensors of hypersurface yn–1 and tensors of embedding space yn . The second non-symmetrical tensor of hypersurface has been introduced, which have been obtained from the analog of Peterson-Codazzi equation in nonsymmetrical case.Also we have introduced the tensor that is associated with square of angle between normal and adjacent normal and it is represented in terms of metric and second tensors of hypersurface. The geodesics on hypersurface have been studied, and nontrivial example of geodesics on hypersurface with torsion and Euclid metric was constructed.
Soybean (Glycine max L.) Response to Lime and Vermicompost Amelioration of Acidic Nitisols of Assosa, North Western Ethiopia
Authors: Adisu Tigist , Wogi Lemma , Feyisa Tesfaye 
Published: March 2019

Acidic soils limit the production potential of crops because of low availability of basic cations and excess of hydrogen (H+) and aluminium (Al3+) in exchangeable forms. In the western part of the country such as Assosa and Wellega, soil acidity is a well-known problem limiting crop productivity. A field study was conducted to assess the effects of lime, vermicompost and their combinations on selected soil physico-chemical properties and responses of soybean grown on acidic Nitisols of Assosa area during 2016 and 2017 main cropping seasons. Soil samples were collected from the experimental site before planting and from plots after harvesting. The collected samples were analysed following the standard methods for soil physico-chemical analysis. The treatments were factorial combinations of four levels of lime (0, 1.62, 3.62 and 4.90 t ha-1) and four levels of vermicompost (0, 1.50, 3.00 and 4.50 t ha-1). The results revealed that soil pH increased from 5.31 – 5.86 pH while exchangeable acidity decreased from 5.46 - 2.85 cmol (+) kg-1 with levels of lime and vermicompost (3.26 with 3 and 4.90 with 4.5) t ha-1 respectively, which resulted in improved soil physico-chemical properties. The combined application of lime and vermicompost also significantly improved the yield related parameters of soybean. The maximum grain yield (1.95t ha-1) was obtained from the combined application of 4.90 ton lime and 3.00 ton vermicompost ha-1 followed by combined application of 3.26 ton lime with 3.00 ton vermicompost ha-1 with non-significant variation. Therefore, the combined application of 3.26 ton lime and 3.00 ton vermicompost ha-1 is a promising alternative amendment for amelioration of acidic Nitisols of Assosa (Amba-12 Kebele) and other similar agro-ecologies for the improvement of soybean production.

Aims: The sphenoid sinus is surrounded by many neurovascular structures which are very vulnerable to intrasphenoid sinus surgeries. The purpose of this study is to investigate the variation of sphenoid sinus structure by CT scan imaging.
Methodology: This is a retrospective study of 3D images of a paranasal sinus in 129 cases. In this study, three-way metering of the sphenoid sinus, additional septum, pneumatization of the period process (PP), anterior clinoid process (ACP) and greater wing of sphenoid and protrusion and dehiscence of adjacent structures will be assessed.
Results: Protrusion of internal carotid artery (ICA), a vidian nerve, maxillary nerve (V2) and optical canal were seen respectively 50.4%, 57.36%, 62.5% and 54.3% but dehiscence of this structure was seen 8.5%, 7%, 3.9% and 6.2%. penumtazition of PP, ACP and greater wing of sphenoid were seen 96.87%, 43.9% and 41.1%. Additional septum also is seen in 76% of the population.
Conclusion: This study demonstrates numerous variations in sphenoid sinus structure. Some of the variations cause many problems during intrasphenoidal surgery. Therefore, physicians should evaluate patients completely before surgery.

Authors: Tikyaa Emmanuel Vezua , Anjorin Francis Oladele , Joseph Emmanuel 
Published: March 2019

Aims: This paper seeks to analyse the characteristics of monthly rainfall pattern in Katsina City in a view to unveiling the trends and describing its dynamics so that adequate recommendations can be made for its modelling.
Study Design: The analysis involves a complete statistical, trend, spectral and nonlinear analysis of the monthly rainfall time series recorded in Katsina.
Place and Duration of Study: Location: Katsina City, Katsina State, Nigeria from 1990 to 2015; a period of 26 years.
Methodology: Secondary data of daily rainfall recorded in Katsina city from 1990 to 2015 was collected from the Nigerian Meteorological Agency (NiMet), and monthly averages were taken to obtain the monthly rainfall data. The data was then subjected to statistical, trend, spectral and nonlinear analysis techniques to reveal the behavioural patterns in the rainfall and also to reveal its underlying dynamics for its future modelling and prediction.
Results: The outcome of this analysis indicates that the monthly rainfall in Katsina exhibits an increasing trend with high variance and right-skewed distribution requiring a maximum of 6 independent variables to model its dynamics. The correlation exponent plot reached a saturation value of 5.892 confirming that the monthly rainfall in Katsina over the last 26 years exhibits low dimensional chaotic behavior while the largest Lyapunov exponent for the monthly rainfall time series in Katsina was also computed and found to be positive, having a value of 0.006055/month confirming the presence of deterministic chaos dynamics and is predictable for the next 165 months.
Conclusion: Since from the findings of this work it is confirmed that the rainfall in Katsina exhibits chaotic behavior with an increasing trend, it is recommended that more drainages and dams be built to provide steady supply of water for agricultural and domestic purposes as well as curtail the menace of flooding and drought which may occur as a result of global warming and climate change.

Published: March 2019

AbstractAlthough rubber bearings are popular in Japan as seismic isolation bearings, spherical sliding bearings (SSBs) or friction pendulum bearings are widely used in many countries, including the U.S. In this study, shake table tests on a braced frame supported by SSBs are carried out, and their dependence on pressure and velocity is investigated. Tests under eccentric dead loads and uplift conditions are also conducted to capture their performance. Analytical models that consider pressure and velocity dependence are proposed, and their validity against the experimental results is discussed.
Development and long‐term stability of a comprehensive daily QA program for a modern pencil beam scanning (PBS) proton therapy delivery system
Authors: Rana Suresh , Bennouna Jaafar , Samuel E. James Jebaseelan , Gutierrez Alonso N. 
Published: March 2019

AbstractPurposeThe main purpose of this study is to demonstrate the clinical implementation of a comprehensive pencil beam scanning (PBS) daily quality assurance (QA) program involving a number of novel QA devices including the Sphinx/Lynx/parallel‐plate (PPC05) ion chamber and HexaCheck/multiple imaging modality isocentricity (MIMI) imaging phantoms. Additionally, the study highlights the importance of testing the connectivity among oncology information system (OIS), beam delivery/imaging systems, and patient position system at a proton center with multi‐vendor equipment and software.MethodsFor dosimetry, a daily QA plan with spot map of four different energies (106, 145, 172, and 221 MeV) is delivered on the delivery system through the OIS. The delivery assesses the dose output, field homogeneity, beam coincidence, beam energy, width, distal‐fall‐off (DFO), and spot characteristics — for example, position, size, and skewness. As a part of mechanical and imaging QA, a treatment plan with the MIMI phantom serving as the patient is transferred from OIS to imaging system. The HexaCheck/MIMI phantoms are used to assess daily laser accuracy, imaging isocenter accuracy, image registration accuracy, and six‐dimensional (6D) positional correction accuracy for the kV imaging system and robotic couch.ResultsThe daily QA results presented herein are based on 202 daily sets of measurements over a period of 10 months. Total time to perform daily QA tasks at our center is under 30 min. The relative difference (Δrel) of daily measurements with respect to baseline was within ± 1% for field homogeneity, ±0.5 mm for range, width and DFO, ±1 mm for spots positions, ±10% for in‐air spot sigma, ±0.5 spot skewness, and ±1 mm for beam coincidence (except 1 case: Δrel = 1.3 mm). The average Δrel in dose output was −0.2% (range: −1.1% to 1.5%). For 6D IGRT QA, the average absolute difference (Δabs) was ≤0.6 ± 0.4 mm for translational and ≤0.5° for rotational shifts.ConclusionThe use of novel QA devices such as the Sphinx in conjunction with the Lynx, PPC05 ion chamber, HexaCheck/MIMI phantoms, and myQA software was shown to provide a comprehensive and efficient method for performing daily QA of a number of system parameters for a modern proton PBS‐dedicated treatment delivery unit.
The roles of meaningfulness and prior knowledge in younger and older adults' memory performance
Authors: Skinner Donald J. , Price Jodi 
Published: March 2019

SummaryMeaningfulness and prior knowledge can have differing effects on both metamemory and memory performance. Personally relevant information may be deemed more meaningful, which often can serve as a mediating factor in memory performance. Additionally, information that is congruent with prior knowledge has been shown to be judged as easier to remember and often is better remembered. Both of these effects are most pronounced in older adults. The current study aimed to examine the impact of meaningfulness and prior knowledge on age‐related differences in metamemory (i.e., judgments of learning) and memory performance (i.e., recall and recognition) by manipulating subjective a priori familiarity and personal relevance using age‐relevant study materials (i.e., a student loan application and a Medicare application). Recall metamemory and recall performance results indicate that older adults, but not younger adults, were able to utilize meaningfulness and prior knowledge to boost memory performance.
In‐Air Bubble Phobicity and Bubble Philicity Depending on the Interfacial Air Cushion: Toward Bubbles Manipulation Using Superhydrophilic Substrates
Authors: Xu Bojie , Wang Qianbin , Meng Qing'an , He Meijin , Guo Cheng , Jiang Lei , Liu Huan 
Published: March 2019

AbstractBubbles, a typical air‐in‐liquid system including both underwater and in‐air bubbles, are important phenomena involved in our daily life and engineering fields. So far, the fundamental and dynamics for in‐air bubbles largely remain unclear. Here, two typical in‐air wetting states of the bubble are revealed: the bubble‐phobic state in which a bubble with a perfect spherical shape stays on the liquid surface but without coalescence with the liquid; and the bubble‐philic state in which a bubble on the liquid substrate gives a quasi‐hemispherical shape. It is proposed that the bubble phobicity is a typical high‐energy state where the air cushion at the bubble/liquid interface plays a crucial role in preventing their coalescence by generating an energy barrier. By applying an external force to overcome the energy barrier, the bubble will distort and finally be stabilized in a bubble‐philic state. It is demonstrated that superhydrophilic substrates enable manipulating bubbles in air: a superhydrophilic surface with microscale hairy textures shows robust in‐air repellence to the bubbles, while a hemispherical bubble is capable of transport directionally in air on a superhydrophilic conical fiber. Here, the concept of superwetting into air‐in‐air system (liquid films) is promoted, which may open a new perspective in surface and interface chemistry.
