Analysis of video sequences: table of content and index creation
This paper deals with the representation of video sequences useful
for tasks such as long-term analysis, indexing or browsing. A Table
Of Content and index creation algorithm is presented, as well as
additional tools involved in their creation. The proposed method
does not assume any a priori knowledge about the content or the
structure of the video. It is therefore a generic technique. Some
examples are presented in order to assess the performance of the

Paying the mortgage: Hyperinflation, reform of the economy, employment and unemployment in the Argentina of the 1990s
(Available only in Spanish) The causes of the "unemployment explosion" and of the scant creation of jobs in Argentina until 1995 and the future outlook are the two themes of this document, which presents an in-depth interpretation of the case of Argentina.
Identifying Critical Factors in Managing University Technology Transfer and Commercialization Units
Given the increasing interest worldwide in the growth of new technology-based companies, the aim of the present paper is to contribute to the future design of patent commercialization and spin-off creation units on behalf of university authorities and national or regional innovation agencies. Our analysis was based on 52 public technology transfer units. Six unit typologies were identified in the analysis. From the results, the proposed recommendations are focused on some critical factors such as a universityâs research mass, specialized personnel of the technology transfer units, their profile, expertise and cost, as well as ideas collected from some experts in the field.university; Science Park; technology transfer; commercialization; spin-off.
Assessing the overall perceived quality of the undergraduate students
Purpose
- The paper is twofold aimed: (i) defining and validating a scale to assess the quality
of the university experienced by students and (ii) analyzing the role of the aforementioned di-
mensions and their impact on studentsâ satisfaction.
Methodology/Approach
- A survey of 2,557 undergraduate students that finished their degrees
in 2013 at universities located in the region of Catalonia has been analyzed using Structural
Equation Modeling (SEM). An exploratory analysis suggests the final dimensions that were
confirmed in a confirmatory analysis. The psychometric characteristics of the scale are provided
to show reliability and validity of the constructs.
An extra model (also using SEM) assesses the impact of these dimensions on overall satisfac-
tion.
Findings
- The quality is a multifactor construct composed by: (i) âsyllabusâ, which refers to
the quality of the learning methods and the coordination efforts through the whole study period;
(ii) âskills developmentâ, referring to the skills that students might acquire along their studies
and (iii) âservices and facilitiesâ of the university.
Moreover, the first and third factors act as âenablersâ for the second factor one. Nevertheless,
only âSyllabusâ dimension affects significantly on studentsâ satisfaction, whereas âservices and
facilitiesâ do not have a significant role, although they are necessary in order to provide a good
service.
Research Limitation/implication
- Although the sample is large enough to draw robust re-
sults, it is limited the Catalonia. The paper provides recommendations for university managers
and public administration authorities in order to allocate the available resources.
Originality/Value of paper
- In an era of global competition, universities are trying to adapt
to these new requirements by expanding they academic offer, introducing innovative teaching
methods, providing teaching resources to lecturers, and updating the general services of the
university among others. All these services will be considered when students evaluate their
experience at the university. The paper contributes with an assessment scale for the holistic
service provided by the university within the period that the student is in the university. These findings can be applied to help define attractive academic programs and provide useful insights
on how the supporting facilities should be designed to allow students take advantage of their
learning process at universities.Postprint (published version

Thus, quinolones are an important class of antibacterials; these agents generally consist of a 1-subtituted-1,4-dihydro-4-oxopyridine-3-carboxylic acid moiety combined with an aromatic or heteroaromatic ring fused at the 5- and 6-position. Aims: To determine the binding of quinolones to DNA gyrase of Escherichia coli. Methods: An analysis was performed using an in silico approach to determine, by docking calculations and energy descriptors, the conformer of 4âoxoâ1,4âdihydroquinoline skeleton that forms the most stable complex with DNA gyrase of E. coli. Results: The complex shows that the pose of the quinolones coincides with the amino acid residues Asp87, Thr88, Arg91 and Met92, which is expected to be critical in the binding of quinolones to DNA gyrase of E. coli. A series of quinolones were computationally designed, and the interactions between the quinolones and the amino acid residues of the DNA gyrase were calculated. Conclusions: Among the designed compounds, compounds 105 and 115 exhibit higher binding energy values and interact with amino acids Asp87, Thr88, Arg91 and Met92. © 2018 Journal of Pharmacy & Pharmacognosy Research.http://jppres.com/jppres/pdf/vol6/jppres18.368_6.5.386.pd
