La teoría de recursos y capacidades: un análisis bibliométrico
Authors: Fong Reynoso Carlos , Flores Valenzuela Karina Edith , Cardoza Campos Luz Melina
Published: September 2017

Introducción: La Teoría de Recursos y Capacidades (TRC) constituye uno de los principales modelos teóricos que guían la investigación que se realiza en Gestión Estratégica, y su utilización es creciente. Esta tendencia, que inicia en los años ochenta del siglo pasado, se explica por distintos factores, entre los que destaca la aceptación, dentro de la comunidad académica asociada a la gestión estratégica, de argumentos de corte económico que se utilizan en este enfoque para explicar el comportamiento y desempeño de la empresa, y en particular, sus mecanismos de construcción y mantenimiento de la ventaja competitiva. La TRC considera que la disposición de una ventaja competitiva expresa que la empresa ha alcanzado un nivel de desempeño superior al de sus competidores, situación que le permite obtener beneficios extraordinarios, aún en el largo plazo. En este sentido, construir y sostener una ventaja competitiva constituye la clave del éxito de la empresa y señala la eficiencia con que la empresa utiliza sus recursos y capacidades.  Método:  Con el objetivo de verificar que las ideas antes señaladas correspondan con las publicaciones en el ámbito, se realiza un análisis de datos bibliométrico para el periodo 2011-2015 (agosto). En éste se identifican los principales tópicos de investigación que se tratan en la TRC, así como la tendencia que se sigue en su desarrollo. El énfasis está en identificar los trabajos más relevantes para su desarrollo, así como en sus principales autores.Resultados: Los datos obtenidos muestran una creciente generación de prueba empírica confirmatoria, el desarrollo de aplicaciones y la contribución de la TRC al desarrollo de otras disciplinas.Conclusión: El fortalecimiento y madurez de la TRC queda manifiesta a través de las publicaciones señaladas en este análisis de datos bibliométrico. Si bien el campo de la TRC es amplio y no permite profundizar en todas sus dimensiones, se puede concluir que los resultados obtenidos en este trabajo confirman que es correcta la percepción de la TRC como uno de los modelos teóricos más importantes para la investigación que se realiza en gestión estratégica.

Numerical investigation of pipe length determination in branched systems by transient tests
Authors: Capponi Caterina , Ferrante Marco
Published: September 2017

Transients are used as a diagnostic tool for pressurized pipes due to their capabilities to acquire and transmit information about system status. To interpret such information in complex systems, models obtained by the integration of the governing equations in the frequency domain are used, since they are computationally efficient and reliable. These models do not require a regular spatial grid for integration and introduce the pipe lengths as parameters. In this paper a calibration procedure based on this particular feature is introduced, to determine a basic item of information that can be lost about the water distribution system, that is the length of the pipes. The network admittance matrix method is implemented and its numerical efficiency allows the investigation of the calibration optimization function on a regular grid in the parameter space. The calibration is tested using in series a genetic and the Nelder–Mead algorithms, considering both elastic and viscoelastic material pipes. The results of the presented numerical investigation allow some insights into the existence of the solution and into the shape of the optimization function.
Effect and Mechanism of Curcumin on EZH2 - miR-101 Regulatory Feedback Loop in Multiple Myeloma
Authors: Wu Chuanqing , Ruan Tuo , Liu Weizhen , Zhu Xiaojie , Pan Juan , Lu Wen , Yan Chen , Tao Kaixiong , Zhang Weikang , Zhang Chun
Published: September 2017

Background:

Multiple myeloma is the second most prevalent hematologic malignancy and thought to
be incurable. Therefore, it’s urgent to find new drugs for treatment. Some experiments have shown that curcumin
might have great potential in treating multiple myeloma, while the mechanism is still unknown. EZH2 and
SUZ12 are the core proteins in PRC2 and their expressions are increased in various human cancers, including the
poor prognostic multiple myeloma. Meanwhile, the regulation of miRNAs and EZH2 has been demonstrated in
other cancer researches, like lung cancer, pancreatic cancer, leukemia and so on.

Objective:

To reveal the mechanism behind the anti-tumor effect of cucurmin in multiple myeloma.

Method:

The effect of curcumin on the growth of MM cells was studied by MTT assay in the MM cell lines
RPMI8226 and U266. Apoptosis was measured by Annexin V-FITC/PI double staining method. Western blotting,
RT-PCR and luciferase activity assay were used to assess the expression of EZH2, SUZ12, miR-101 and downstream
proteins such as E-cadherin, MMP9, c-Myc, cyclin D3, CDK4 and CDK6.

Results:

Curcumin could significantly inhibite the proliferation of MM cells in a time- and concentrationdependent
manner. Curcumin induced apoptosis by inhibiting the expression of EZH2, and the apoptosis rates
were 16.42% and 25.62% when the RPMI8226 cells incubated with 5 and 10 µmol/L of curcumin. For U266
cells, the apoptosis rates were 15.25% and 21.28%. The up-regulation of miR-101 led to the lower expression of
EZH2. In adverse, the expression of EZH2 induced lower expression of miR-101. The down-stream proteins of
miR-101 were regulated by curcumin and EZH2 at the same time.

Conclusion:

Our experiments verified that the effect and mechanism of curcumin on multiple myeloma is via
EZH2 – miR-101 regulatory feedback loop, which would lead us to a new way of investigating multiple myeloma
and come up with new therapies in treating the disease.
Ephedrines as Chiral Auxiliaries in Enantioselective Alkylation Reactions of Acyl Ephedrine Amides and Esters: A Review
Authors: Cruz Alejandro , Padilla-Martínez Itzia I. , Bautista-Ramirez Maria E.
Published: September 2017

Background:

In modern chemistry, the asymmetric synthesis for the preparation of high purity
chiral compounds to be used as pharmaceuticals or additives in foods have been of capital importance. Chiral
auxiliary reagents are used to control the stereochemistry of the reaction in the generation of new chiral compounds,
in this context, Ephedra compounds (ephedrines and pseudoephedrines) and some of their derivatives
have been broadly used as chiral ligands in catalysis or chiral inductors in asymmetric synthesis.

Objective:

This review focuses on recent progress in the use of ephedra compounds and their N-substituted derivatives
as chiral auxiliaries in the area of asymmetric synthesis, via the alkylation reaction of the enolates derived
from their corresponding N-Acyl or O-Acyl derivatives, in the C-C bond formation.

Conclusion:

A vast amount of work has been done about the use of ephedra compounds in asymmetric synthesis
area, in general, it was found that pseudoephedrines are much more effective than ephedrines and are preferred
as chiral auxiliaries in the asymmetric alkylation of the corresponding N-acyl amides or O-Acyl esters.
Alkylation with alkyl halides requires the use of more than 4 equivalents of LiCl to accelerate the alkylation
rate and to complete the reaction without effecting the diastereoselectivity of the process. In contrast, the use of
secondary alkyl halides was found to make the reaction very slow. Furthermore, a lot of work about the alkylation
reaction in the opening of epoxides and aziridines, aldolic condensation, Manich reaction, addition of nucleophiles
to α,β-unsaturated ephedrine amides and Michael additions have been demonstrated to be effective
in the C-C bond formation. The aldol reaction of chiral enolates, proceeds with decreasing yields and enantioselectivities
as the steric demand of the α-R of ephedrine amides and the size of carbonyl compound increase.
In addition, the use of branched groups on N,N-disubstituted norephedrine esters is highly recommended in the
aldol reactions of aromatic and aliphatic aldehydes.In the case of N-Acyl or O-Acyl ephedrines supported on
polymers, the reaction proceed with good enantioselectivities but low yields, the enantioselectivities are goods
but the yields are low. In general, the removal step of the auxiliary proceeds with low to high yields but without
epimerization.
Study of chloride concentration of Nira River, Pune, Maharashtra, India.
Authors: Jadhav Shivaji , Jadhav Mrunalini
Published: September 2017

The present work deals with the study of Chloride concentration of Nira River in the year 2016. Fresh water is essential to existence of life. Acceptable quality water is essential not only for drinking and domestic purposes but also for agriculture, industrial and commercial uses. Chloride occurs naturally in all types of water. In natural fresh water, the concentration is quite low. The important source of chloride in the water is the discharge of domestic sewage. Chlorides are highly soluble in water so they do not get precipitate and cannot be removed by biological treatment of water. If the amount of chloride is beyond the permissible limit then it can corrode by extracting calcium in the form of calcide. Here in the present work the amount of chloride observed is within the permissible limit for Nira river.

Application of a complex assessment of landslide hazards in mountain regions
Authors: Boyko Kateryna
Published: September 2017

The main regional factors of occurrence and activation of landslides within the mountain region were examined. As a result of study of recommendations made by experts, geologists, and gap analysis of existing methods of forecasting the landslide process, an algorithm of comprehensive assessment of landslide hazard areas based on the construction of models in a GIS environment was proposed. These models describe the spatial patterns of landslides. All factors determining the tendency of the studies area to the landslide process development were divided into actual factors, reflecting the regional peculiarities of the territory and forming the landslide-prone slopes (static model), as well as triggering factors, initiating the landslide process and determining its activity (dynamic model). The first cartographic model was built, showing the distribution of the deterministic indirect indicator of landslide hazard, i.e. stability index.

Comparison between deformation modulus of rock mass measured by plate jacking and dilatometer tests
Authors: Rezaei Mohsen , Ajalloeian Rasoul , Ghafoori Mohammad
Published: September 2017

For determination of the in-situ deformation modulus of rock mass at Bakhtiari Dam site, located in south-west of Iran, plate jacking tests (PJT) and dilatometer tests (DLT) carried out during the geotechnical investigations. In this study, the results of PJTs and DLTs were compared. This comparison involves 89 vertical and horizontal PJTs and 83 DLTs carried out in 6 rock units of Sarvak formation. Although, both PJTs and DLTs in the Bakhtiari Dam site were performed in same geological and geotechnical conditions, but there are not sufficient side by side data to make a paired two samples correlation. Therefore, the mean of in-situ data was compared at each rock unit. Besides Mann–Whitney U tests were performed to compare in-situ test results. The comparison shows that the deformation modulus measured by both methods has no significant differences. However, in low quality rock masses the moduli measured by the use of DLTs were greater than the modulus measured by PJTs. Conversely, in high quality rock masses the results of PJTs were greater than DLT’s.
Wykorzystanie metod GIS do wyznaczania działów wodnych zlewni zurbanizowanych na przykładzie miasta Kielce
Authors: Wałek Grzegorz
Published: September 2017

The paper presents the analysis of the area and reach of the Silnica river catchment and its six subcatchments delineated using GIS in three different variants: DEM (from Computerized Information System of Country Protection project; Polish: ISOK) in one-meter resolution, the Database of Topographic Objects (Polish: BDOT) in 1 : 10 000 scale and the Geodetic Utilities Network System (Polish: GESUT). A topographic map in 1 : 10 00 scale was also compared with the Map of Hydrographic Division of Poland (Polish: MPHP) and the differences in the catchment reach resulting from this comparison were also examined. The course of delineated drainage divides varied in each variant resulting in differences in the area and reach of the analyzed catchments. The best results in urban catchments delineation were obtained in GIS using DEM and corrected vector data from BDOT and GESUT databases. In this case, the catchments’ reach overlapped with the existing drainage network. Traditional methods with the use of topographic maps and data from MPHP 1 : 10 000 scale proved to be less accurate as far as the reach of the Silnica river catchment was concerned and were useless in delineating the Silnica sub-catchments in Kielce city center.

An Introduction to Services Accessible on the Internet
Authors: Giguère Marlene
Published: September 2017

The Internet is an international wide area network linking computers in research and educational institutions in more than thirty countries. Services include access to electronic mail and bulletin board facilities, access to machine-readable texts such as electronic serials, and the capacity to download complex text files and software. As libraries inevitably move toward greater cooperative resource sharing, the Internet will become an increasingly important tool in providing access to these resources. Libraries suffering from budget cutbacks must look for alternative and creative ways of providing the same level of service with decreasing physical and personnel resources. The Internet, an internationaltelecommunications and computer network, is potentially a tool which can expand a library's access to a vast range of services without increasing costs. For authorized users, generally transmitting on the Internet is free. In addition many of the services accessible on the Internet are also free of charge. The objective of this article is to explain what the Internet is and how it can be used advantageously in libraries. The strength of this network is in the types of services and the range of resources which it makes aocessible. The article will provide an overview of the electronic mail service, bulletin boards and electronicpublications available, as well as information on accessing online public access catalogs, databases and archives.
The Review of the J .A. Turner Professional Library Part II: The Qualitative Component
Authors: Wilkins Catherine E.
Published: September 2017

The setting for this study was the J.A. Turner Professional Library which is the central corporate Professional Library for the Peel Board of Education which is the largest Public School Board in Canada. The library also provides library services for educators in graduate programs at Brock University, the Ontario Institute for Studies in Education, York University, and the Faculty of Education University of Toronto to support their professional development and continuing education needs. The focus for the study were the Peel and Brock consumer groups so as to allow for comparisons. The purpose of this study was to evaluate the services and resources of theJ.A. Turner Professional Library by ascertaining the views and opinions of two consumer groups of the Professional Library at the Peel Board of Education. The author initiated the evaluation for several reasons including: her belief that the library as a service component of the organization must ensure that it's objectives fit the organizational culture and as the Peel Board was committed to organizational renewal i.e., strategic planning so was the library. The sample consisted of library users drawn from two consumer groups of which there were 127 Peel and 50 Brock users, and 32 Peel and three Brock stakeholders. The data collection consisted of a self-reporting questionnaire and selected interviews. For the purpose of analysis the responses were divided into the following two groups Peel Board of Education and Brock users. The results indicate that there is a high level of support for the J.A. Turner Professional Library. The interviews provided future directions for the development of the J .A.Turner Professional Library. The study closes with a series of recommendations to enhance the operation of the J.A. Turner Professional Library within the organizational context of the Peel Board of Education.

Generating faculty involvement in the enterprise, creating a database to provide bibliographic control and efficient collection maintenance, and distributing responsibility for the collection between two library departments were key elements of the procedure. Appointment of a separate line-item in the library budget for test acquisitions, rapid completion of the project (less than six months), and development of a test database were the most notable results of this project.
Using OCLC to Create a Core List of Educational Titles
Authors: D'Amicantonlo John , Campbell Janet
Published: September 2017

The authors have prepared below a bibliography of core holdings for libraries that include materials for teacher education. All the materials listed are held by over 100 libraries nationwide. Several of the titles are, in fact, held by over 400libraries. When the authors originally began to consider developing a core collection of educational materials they were motivated by a desire to target books that would benefit students in the Graduate School of Education (GSE). With the onslaught of reduced book budgets and diminishing staff in libraries and universities, it has become even more imperative to identify methods of helping students that are less labor intensive. Librarians at California State University, Long Beach (CSULB) havedeveloped bibliographies of appropriate subject holdings for years, so updating an existing bibliography of educational materials seemed logical.

Although most of the programs administered in my Office primarily benefit public and academic libraries, several of our programs can significantly benefit special libraries and school libraries. I do realize also that many of the libraries represented in the Education Division are in academic libraries. Of course, in this day of electronic resource-sharing, strengthening any library of any type that is connected to a major network such as the Internet strengthens all libraries of any and every type that are also connected to the Internet.

SOME PORTRAYALS OF LIBRARIANS IN FICTION - A DISCUSSION
Authors: Brown-Syed Christopher , Sands Charles Barnard
Published: September 2017

This article explores portrayals of librarians in selected works of fiction, notably those involving mystery or detection. It begins with a summary of information derived from descriptions of about one hundred and twenty contemporary or recent works, then discusses particular stories involving detection or mystery, with occasional references to other genres such as science fiction, historical fiction, espionage, and romance.      In 1996, we began to compile a bibliography of fiction involving librarians to accompany a graduate course introducing the profession. Entries were obtained through searches of online catalogues and databases, as well as through queries posted over Internet LISTSERVs. About 120 individual works and about a dozen bibliographies were included in the resulting list.       In many instances, librarians and their places of work were presented as intrinsically interesting and appealing. In more than half of the works, librarians played leading or major supporting roles. Following a categorization of the roles of librarians in these works, the article examines images of the profession in the works of Umberto Eco, L.R. Wright, and Charlotte McLeod.       We contend that, even in works which present casual glimpses of the profession, or even in those which stress less desirable images of its members, accurate details of its techniques and working realities are sometimes discernible. We suggest that further research concentrate upon the work done by fictitious librarians and upon their centrality to plots.
JSTOR - An Update on Content
Authors: Sully Sarah E.
Published: September 2017

This article explains the role of JSTOR, which has selected and electronically converted 100 of the earliest and most important scholarly literature in the humanities and social sciences. Its database now contains over 2 million pages and continues to expand. Old files are digitized from the firstissue published. Database usage by both publishers and college/university staff and students is growing rapidly, and increases in production capacity are ongoing. JSTOR plans to offer access to the relevant fields which libraries prefer rather than encompass a whole cross-disciplinary group. To ensure useful and well-rounded titles, experts in the field are consulted to rank the most important files. Response to JSTOR's accomplishments to date has been overwhelmingly enthusiastic.
COPYRIGHT ISSUES IN CREATING DIGITAL ARCHIVES
Authors: Gasaway Laura N.
Published: September 2017

As digital archives continue to increase, libraries must face concerns relating to copyright, and find workable, legal solutions to these issues. This article describes three types of digital library projects. Public domain material and its accompanying copyright implications are first described. These include works on which copyright has expired; materials of unclaimed copyright and the current restraints; and works produced by the federal government. Second is a discussion on fair use of copyrighted works. Third, issues surrounding uncertain copyright status are explored. License agreements, particularly in relation to interlibrary loans, and cooperative projects wherein agreements are reached between owner and library so that no copyright problems exist, are also covered. The author concludes that while the creation of digital libraries brings copyright problems with it, these are not insurmountable and explains why.
THE VIRTUAL LIBRARY FOR BLIND AND PRINT DISABLED CANADIAN STUDENTS
Authors: Kavanagh Rosemary
Published: September 2017

As the Information Age progresses in technological and electronic areas, so mustlibrarians re-define traditional services for those both with. and without sight. Libraries are expected to participate in setting new and better service standards for those with visual disabi lities and/or learning disorders. The Canadian National Institute for the Blind (CNIB) Library's national network (VISUNET: CANADA) supports the premise of a virtual library for print disabled C an adians. Information resources, services, and international collaborations such as the Digital Audio Based Information System (DAISY) are producing accessible materials for those who cannot read print. By interconnecting world information resources in any format of choice, and providing the best in content that is both digital and virtual with no limitations, libraries will assist print disabled Canadians to better compete for jobs in a rapidly changing working and learning environment.

Authors: Locke Joanne
Published: September 2017

Staff training and development, an aspect of continuing education, has long been recognized as an essential process in the practice of the library and information science profession. This expression of need by both the employee and the employeris a central point of the literature today and parallels that of over thirty years ago when Cyril O. Houle cited four specific areas of development required by the practicing professional in his article entitled "The Role of Continuing Education in Current Professional Development."
THE PRISON LIBRARY: A VITAL LINK TO EDUCATION, REHABILITATION, AND RECREATION
Authors: Lehmann Vibeke
Published: September 2017

This article has been adapted from a paper presented by the author in Cienfuegos, Cuba, November 1999 at the invitation ofUNEAC (Union Nacional de Escritores y Aristas Cubano) and the provincial public library in Cienfuegos.       In cooperation with other prison programs the prison library plays a critical part in the education and rehabilitation of incarcerated persons. The background, roles, services, and ways in which the modern prison library can meet the needs of both inmates and prison staff are examined in depth. International and national standards exist as tools that cover all aspects of prison library operations. The most vital link in the operation of such libraries is having competent, well-trained, enthusiastic, and patient library staff equipped with the special human skills needed to deal with difficult prison patrons.

Visual Literacy and Library Instruction: A Critical Analysis
Authors: Nelson Nerissa
Published: September 2017

This paper discusses the concept of visual literacy and its implications for librarians teaching information literacy components. The author concludes that, while visual teaching methods should be incorporated in library instruction, teaching visual literacy competencies is most effectively done in connection with discipline-specific content and thus falls outside librarians' role.

A Revolution in Academic Publication
Authors: Webber Charles F.
Published: September 2017

This paper discusses some of the issues related to e-journals: cost, speed of publication, global access, the politics of academic publication, and reduced control of publication houses. E-journals are also examined relative to their impact on academic responsibility, the peer review process, censorship, credibility, and academic literacy skill development. Commonly-cited drawbacks of e-journals are critiqued, e.g., archiving, range of quality, institutional acceptance, cost of technology, and plagiarism. The paper proposes a framework for assessing both e-journals and traditional print journals.

In addition, the skills mastered and activities explored in this course logically transfer to research projects assigned in future graduate courses.
Digital literacy practices among youth populations: A review of the literature
Authors: Blummer Barbara
Published: September 2017

Digital literacy includes a range of abilities from basic computing skills to the creation of multimodal texts. This literature review examines eleven articles that track the digital literacy practices of youth populations or individualsbetween the ages of 12 and 17. It describes the practices of these individuals through three perspectives, including: studies centered on general youth populations, research discussing innovative programs targeting students from low income families, and articles tracking digital literacy competencies among young immigrant learners. Foremost, the articles highlight young people’s efforts to express themselves through their own online literacy. To this end it remains essential that educators correlate students’ digital literacy habits in their personal lives to instructional practices in school.
