Projective bundles over small covers and the bundle triviality problem
Authors: Kuroki Shintarô , Lü Zhi 
Published: July 2015

Abstract
The present paper investigates the projective bundles over small covers.
We first give a necessary and sufficient condition for the projectivization of a real vector bundle over a small cover to be a small cover.
Then associated with moment-angle manifolds, we further study the structure of such a projectivization as a small cover by introducing a new characteristic function on simple convex polytopes.
As an application, we characterize the real projective bundles over 2-dimensional small covers by interpreting the fiber sum operation to some combinatorial operation.
We next determine when the projectivization of Whitney sum of the tautological line bundle
and the tangent bundle over real projective space is diffeomorphic to the product of two real projective spaces.
This answers an open question regarding the topology of the fiber of the Monster-Semple tower.

Abstract
PbS nanostructures were synthesized successfully via hydrothermal approach with a new precursor. The products were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and UV–Vis diffuse reflectance spectroscopy (DRS). The effect of different sulfur sources were investigated on product size and morphology.
M-bias, Butterfly Bias, and Butterfly Bias with Correlated Causes – A Comment on Ding and Miratrix (2015)
Authors: Thoemmes Felix 
Published: July 2015

AbstractDing and Miratrix [1] recently concluded that adjustment on a pre-treatment covariate is almost always preferable to reduce bias. I extend the examined parameter space of the models considered by Ding and Miratrix, and consider slight extensions of their models as well. Similar to the conclusion by Pearl [7], I identify constellations in which bias due to adjustment, or failing to adjust is symmetrical, but also confirm some findings of Ding and Miratrix.
Experimental study and first thermodynamic law analysis of a solar water heater system
Authors: Madadi Vahid , Beheshti Hamid , Tavakoli Touraj , Rahimi Amir 
Published: July 2015

Abstract
The performance of a pilot scale flat plate solar water heater system is
investigated theoretically and experimentally. The effect of the operating
conditions and characteristic factors of the collector on the system
efficiency is studied. A conceptual mathematical model is developed in
order to analyze the system behavior in different operating conditions by
considering the physical and constructive aspects of the system. The
accuracy of the model result is estimated by comparing the model results
with the existing experimental data. The highest obtained system thermal
efficiency is 45%, and the optimum local values for surface azimuth and
tilt angles are obtained at 180 degrees from north and 33 degrees,
respectively, for the constructed solar water heater in Isfahan, Iran, with
the local latitude of

Irrationality and Self-Deception within Kant’s Grades of Evil
Authors: Rukgaber Matthew S. 
Published: July 2015

Abstract:Scholars have failed to adequately distinguish Kant’s grades of evil: frailty (weakness of will), impurity, and depravity. I argue that the only way to distinguish them is, f irstly, to recognize that frailty is explicitly, practically irrational and not caused by any sort of self-deception. Instead, it is caused by the radical evil that Kant finds within the character of all persons. Secondly, impurity can only be understood to be self-deception either about the nature of the act itself, which results in an epistemic error, or about one’s motivations for following a properly reasoned, moral conclusion, which results in a motivational error. Thirdly, depravity is self-deception about morality itself, by which the agent believes that it is morally right to follow self-love.

Heraclitus’ Fragment B 52 DK Re-examined
Authors: Šćepanović Sandra 
Published: July 2015

AbstractThis paper (re-)examines two sources of information about Heraclitus’ fragment 22 B 52 DK, which are at the same time the sources of confusion when it comes to its interpretation: the meanings of the lexical elements that constitute the saying and the ancient testimonies that refer to it. The relevant ancient sources commonly recognise the importance of the theme of the unity of opposites in the fragment and the analysis of the fragment’s wording yields the same conclusion. It renders the saying as an original take on the popular subject of the unpredictability of human existence: the central paradox of the πεσσεία-playing child illustrates the essential uniformity behind the apparent changeability of the course of human life. Thus, the fragment may be seen as yet another expression of the universal rule of law and regularity characteristic of Heraclitus’ philosophy.
Netizen communicology: China daily and the Internet construction of group culture
Authors: Lanigan Richard L. 
Published: July 2015

AbstractIntercultural communicology is a complex system of intergroup communication and, in consequence, is a specialized case of human communication in which discourse is constructed in a semiotic world of experience, i.e., the Semiosphere. I look at the Netizen (online citizen) application of semiotic phenomenological theories and categories as we explore their emblematic presence as cosmologies and logics in the sociocultural discourses of the People’s Republic of China. The analysis examines stories published (2010–2011) in the online version of China Daily, a quasi-official newspaper of the Chinese government. The analysis is the main task that Umberto Eco called the semiotic quest for “the logic of culture”. I shall periodically cite the longitudinal statistical research of Richard E. Nisbett reported in his popular book The Geography of Thought. It is important to note that Nisbett’s research confirms the applied practice of the cultural group semiotic in use, rather than theoretically describing the logic constituted by the semiotic systems, which is my goal. In consequence as we shall see, Nisbett makes the mistake of describing the Asian semiotic in terms of a Western logic perspective – not the Asian perspective per se!
Az első világháború előtti katolikus nagygyűlések és a katolikus egyetem ügye Magyarországon
Authors: Csibi Norbert 
Published: July 2015

During the 18th–19th centuries major universities in Europe significantly changed, and came under the influence of nation states. The Catholic Church, which always had an important role in the European scientific world, and established and maintained several Universities, had to answer a number of questions related to this fact. It was also important for her since the scientific-technical progress had a side effect which made more and more intellectuals turn away from religion. Nevertheless, this social group was exactly the key to perform a catholic reform.
From the turn of the 19th and the 20th centuries, following the paradigm of foreign examples, congresses organized by the Catholics became regular in Hungary. After the sporadic and regional events of the 1890s, from 1900 these musters of the catholic public life were organized in the capital. The questions of public education – beside other religious and social issues – were always important parts in the agenda of these 2–3-day long events. The plans related to the foundation of a new Catholic University in Hungary were important issues of this topic before the First World War. In my paper I show the main proposals of these Hungarian plans in relations to the respective Vatican guidelines as well as to the foreign paradigms.
High Efficiency, Homology-Directed Genome Editing in Caenorhabditis elegans Using CRISPR-Cas9 Ribonucleoprotein Complexes
Authors: Paix Alexandre , Folkmann Andrew , Rasoloson Dominique , Seydoux Geraldine 
Published: July 2015

Abstract
Homology-directed repair (HDR) of breaks induced by the RNA-programmed nuclease Cas9 has become a popular method for genome editing in several organisms. Most HDR protocols rely on plasmid-based expression of Cas9 and the gene-specific guide RNAs. Here we report that direct injection of in vitro–assembled Cas9-CRISPR RNA (crRNA) trans-activating crRNA (tracrRNA) ribonucleoprotein complexes into the gonad of Caenorhabditis elegans yields HDR edits at a high frequency. Building on our earlier finding that PCR fragments with 35-base homology are efficient repair templates, we developed an entirely cloning-free protocol for the generation of seamless HDR edits without selection. Combined with the co-CRISPR method, this protocol is sufficiently robust for use with low-efficiency guide RNAs and to generate complex edits, including ORF replacement and simultaneous tagging of two genes with fluorescent proteins.

A Collective Model of Advanced Teacher Training: An International Experience
Authors: Rubashkin Dmitri 
Published: July 2015

The conventional course-based teacher training method doesn’t meet the requirements of time, and neither does the reproductive teaching style. The paper offers a new alternative to that system, which is project-based and result-oriented advanced training designed to stimulate creative thinking in teachers and to enhance the role of self-analysis and self-assessment. The main idea of this teacher training method lies in collaboration of teachers within a school to create new learning practices based on electronic learning materials and program tools. The paper describes terms and results of the international education project “ICT Learning Environment. Create and Use Together”, which was realized in 2010–2012 and involved Russian and Finnish teachers and experts. Five school teams from Russia (represented by Saint Petersburg) and five from Finland had a mission of learning new technologies, developing new electronic learning materials and implementing them in their own teaching practices. The school teams collaborated for two years during live and online seminars, exchanged emails and talked on Skype, developing the selected projects together. The author investigates into the two factors of assessing team project efficiency: a) participants’ self-assessment of progress in their professional development and b) quality of created learning materials as finished products to be copied and distributed across the educational system. The paper provides benefits of the cluster-based model of project cooperation among teachers, which consists in grouping bunches of schools into clusters by geography or common teaching approaches.
Is it Possible to Compare USE and SFA: A Comparison of Indicators Calculated on the Basis of Different Tests
Authors: Agranovich Mark 
Published: July 2015

The article discusses the possibilities of different tests results comparisons. The issue of correct compare of different tests results raises in relation of analysis of tests results for different years and in a number of other cases. These results could not be compared directly, without some adjustments. The article presents the approach to make tests results with different parameters of distribution comparable. The suggested approach based on the assumption that the level of students’ knowledge in different subjects are more or less equal and differences in parameters of tests results distributions arise due to instruments and differences in testing scaling. Suggested scheme of using statistical methods allow to eliminate these differences in testing instruments and make results of different tests comparable. Applications of the suggested method is shown on an example of comparison of results of Unified State Exam (upper secondary graduation tests) in different subjects and for different years, and also comparison of Unified State Exam and State Final Attestation (low secondary graduation tests) results. The sphere of application for the suggested method is limited by the following conditions: the number of objects should be sufficient to use mathematical statistics tools applied to evaluate the closeness of relationship; the paper compares the sets of values obtained in different tests for the same objects.
