VIREO @ TRECVID 2015: Video Hyperlinking (LNK)

This paper presents an overview and comparative analysis of our system designed for TRECVID 2015 [1] video hyperlinking (LNK) task. The application scenario for video hyperlinking is to satisfy the needs of users to find further information on the content of interest contained within an anchor. The task here is given an anchor to generate a ranked list of video segments relevant to the name entities extracted from the anchor. Our four runs are summarized below: - tf-idf : The subtitles of video segments are indexed with Lucene [2] and more like this (MLT) query is adopted for tf-idf based retrieval. - word2vec: Each video segment is represented by uniformly summing the vector representations of words in subtitles using Word2Vec [3, 4] and the relevant segments are ranked based on cosine similarity.
Evaluating damping elements for two-stage suspension vehicles

The technical state of the damping elements for a vehicle having two-stage suspension was evaluated by using numerical models based on the multi-body system theory; a set of virtual tests used the eigenproblem mathematical method. A test was developed based on experimental modal analysis (EMA) applied to a physical system as the basis for validating the numerical models. The study focused on evaluating vehicle dynamics to determine the influence of the dampers’ technical state in each suspension state.
Bohemia and economic geography

This paper examines the geography of bohemia and the relationships between it, human capital, and high-technology industries. The underlying hypothesis is that the presence and concentration of bohemians in an area creates an environment or milieu that attracts other types of talented or high human capital individuals. The presence of such human capital in turn attracts and generates innovative, technology-based industries. To explore these factors, this paper introduces a new measure--the bohemian index --that directly measures the bohemian population at the MSA level. Statistical research examines the relationships between geographic concentrations of bohemians, human capital, and high-technology industry concentration. The findings support this hypothesis. The geography of bohemia is highly concentrated. The results indicate positive and significant relationships between the bohemian index and concentrations of high human capital individuals and between the bohemian index and concentrations of high-technology industry. The relationship between the bohemian index and high-technology concentrations is particularly strong. Copyright 2002, Oxford University Press.
Crystallinity of Electrospun and Centrifugal Spun Polycaprolactone Fibers: A Comparative Study

Crystalline properties of semicrystalline polymers are very important parameters that can influence the application area. The internal structure, like the mentioned crystalline properties, of polymers can be influenced by the production technology itself and by changing technology parameters. The present work is devoted to testing of electrospun and centrifugal spun fibrous and nanofibrous materials and compare them to foils and granules made from the same raw polymer. The test setup reveals the structural differences caused by the production technology. Effects of average molecular weight are also exhibited. The applied biodegradable and biocompatible polymer is polycaprolactone (PCL) as it is a widespread material for medical purposes. The crystallinity of PCL has significant effect on rate of degradation that is an important parameter for a biodegradable material and determines the applicability. The results of differential scanning calorimetry (DSC) showed that, at the degree of crystallinity, there is a minor difference between the electrospun and centrifugal spun fibrous materials. However, the significant influence of polymer molecular weight was exhibited. The morphology of the fibrous materials, represented by fiber diameter, also did not demonstrate any connection to final measured crystallinity degree of the tested materials.
Common and Idiosyncratic Factors of the Exchange Risk Premium in Emerging European Markets

Existing empirical evidence suggests that the Uncovered Interest Rate Parity (UIRP) condition may not hold due to an exchange risk premium. For a panel data set of eleven emerging European economies we decompose this exchange risk premium into an idiosyncratic (country-specific) elements and a common factor using a principal components approach. We present evidence of a stationary idiosyncratic component and nonstationary common factor. This result leads to the conclusion of a nonstationary risk premium for these countries and a violation of the UIRP in the long-run, which is in contrast to previous studies often documenting a stationary premium in developed countries. Furthermore, we report that the variation in the premium is largely attributable to a common factor influenced by economic developments in the United States.
The rheophysics of two athermal systems: dry granular media and non-Brownian suspensions

The steady-state, pressure-controlled simple shear flow constitutes a paradigm for the study of flows of dense athermal systems such as dry grains or non-Brownian suspensions. The introduction of two dimensionless numbers called inertial and viscous was an important step. In an attempt to provide a common rheophysical framework to both systems, we relate their flow properties in the dense regime close to jamming transition to two basic constitutive laws or equations of state : both the free volume and the ratio of shear stress to particle pressure (in excess of a static friction coefficient) vary as power laws, with systemdependent exponents, of a Deborah number. The first law is derived from the Boltzmann equation expressed in the approximation of relaxation. The second law is deduced from the expression of the probability for a particle to belong to a transient cluster of particles in contact.

A Study of the Factors Influencing Adoption of Mobile VoIP: Applying the UTAUT Model

Abstract The progress of Information Technology enables people can communicate each others using the Internet. As a smartphone proliferates, many free mobile VoIP(Voice over IP) application are developed and accepted by smartphone users. In this study we investigate the factors affecting the acceptance of mobile VoIP applications and the structural relationship among these factors. We review the related works and extract the related factors and build a research model describing the causal relationship among these factors. We conduct an empirical study - a survey and statistical analysis - to verify the research model. EFA(Exploratory Factor Analysis) is applied for variables in the survey and SEM(Structural Equation Model) is used to reveal the structural relationship among the factors. We can find that two factors - usefulness of mobile VoIP and social influence - positively affect usage intention and actual use. These findings imply that it is required to emphasize the benefits of mobile VoIP use and add S/W functionalities enhancing social influence.
ASSOCIATION BETWEEN DRINIKING GOAL AND ALCOHOL USE ONE YEAR AFTER RESIDENTIAL TREATMENT: A MULICENTER STUDY

This study examined whether patients’ drinking goals at admission to and discharge from 12 residential alcohol use disorder treatment programmes were associated with alcohol-related outcomes at 1-year follow-up. Detoxified patients (N=289) completed assessments at admission, after treatment, and at 1-year follow-up. Drinking goals of abstinence, conditional abstinence (in principle abstinence but potential occurrence of lapses or drinking, when urges are strong), and controlled drinking changed during treatment and predicted the 1-year follow-up outcomes (abstinence, number of standard drinks, and number of days to the first alcohol use). Goals at discharge had a better predictive value. The goal of abstinence at discharge had better outcomes than conditional abstinence; the poorest had controlled drinking.
The complex dynamics of the seasonal component of USA's surface temperature

Abstract. The dynamics of the climate system has been investigated by analyzing the complex seasonal oscillation of monthly averaged temperatures recorded at 1167 stations covering the whole USA. We found the presence of an orbit-climate relationship on time scales remarkably shorter than the Milankovitch period {related to the nutational forcing}. The relationship manifests itself through occasional destabilization of the phase of the seasonal component due to the local changing of balance between direct insolation and the net energy received by the Earth. Quite surprisingly, we found that the local intermittent dynamics is modulated by a periodic component of about 18.6 yr due to the nutation of the Earth, which represents the main modulation of the Earth's precession. The global effect in the last century results in a cumulative phase-shift of about 1.74 days towards earlier seasons, in agreement with the phase shift expected from the Earth's precession. The climate dynamics of the seasonal cycle can be described through a nonlinear circle-map, indicating that the destabilization process can be associated to intermittent transitions from quasi-periodicity to chaos.
Antibiofilm efficacy of silver nanoparticles against biofilm forming multidrug resistant clinical isolates

Purpose: The purpose of this study was to assess the antibiofilm activity of silver nanoparticles (AgNPs) against multidrug resistant gram negative bacterial isolates. Different approaches have been used for preventing biofilm-related infections in health care settings. Many of these methods have their own difficulty, which include chemical-based complications; emergent antibiotic resistant strains, etc. Therefore, the aim of present study was to demonstrate the anti-biofilm activity of silver nanoparticles against the selected five strong biofilm forming multidrug resistant gram negative bacterial strains includes {Escherichia coli (ETEC12), Klebsiella pneumoniae (SKP7), Pseudomonas aeruginosa (ETPS11), Proteus mirabilis (PPM8) and Acinetobacter baumannii (SAB5)} were used in this study. Methods: The anti-biofilm activity of AgNPs with different concentration of 12.5 to 100 μg/ml was investigated by direct visualisation applying test tube method and congo red agar method along with scanning electron microscopy (SEM) techniques. Results: The biofilm inhibitory concentration was found to be in the range of 12.5 – 100 μg/ml. The technique using SEM provides the visual evidence that AgNPs arrested the bacterial growth and prevent the exopolysaccharides formation. The AgNPs effectively restricted biofilm formation of the tested bacteria. In our study, we could expose the complete anti-biofilm activity of AgNPs at a concentration as low as 100 μg/ml. Conclusions: Our findings suggested that AgNPs can be defeated towards the development of potential anti-bacterial coatings for various biomedical and environmental applications. In future, the AgNPs may play major role in the coating of medical devices and treatment of infections caused due to extensively antibiotic resistant biofilm.
Filling Position of Governor and Vice Governor of Yogyakarta Special Region in Indonesia

Act No. 13 Year 2012 on Previleges of Yogyakarta as a Special Region provides a constitutional basis in establishing that the Governor was enthroned as Sultan and to the Vice Governor as Adipati Paku Alam. However, in the case of succession of the Governor of Yogyakarta, there is an exception because it is basically a privileges of DIY that has been existing since Indonesia had not gotten its independent yet and it is also guaranteed by the constitution. The direct appointment of Sultan and Paku Alam is intended to award to the diversity of customs and cultures among the people of different regions. From the results of research and study shows that filling positions of Governor and Vice Governor of Yogyakarta through appointment mechanism is accordance with the principles of a democratic constitutional state.
The Causes of Fiscal Transparency: Evidence from the U.S. States

We use unique panel data on the evolution of transparent budget procedures in the U.S. states over the past three decades to explore the political and economic determinants of fiscal transparency. Our case studies and quantitative analysis suggest that both politics and fiscal policy outcomes influence the level of transparency. More equal political competition and power sharing are associated with both greater levels of and increases in fiscal transparency during the sample period. Political polarization and past fiscal conditions, in particular state government debt and budget imbalances, also appear to affect the level of transparency.

Inflation persistence and bargained firing costs

We study the effect of bank loan and bond announcements on borrower’s stock price. We apply an event study methodology on a sample of companies from 17 European countries. We find that debt announcement generates a positive stock market reaction. However our main conclusion is that the issuance of a loan exerts a significantly higher reaction than the issuance of a bond. This finding supports the hypothesis that loan issuance conveys a positive certification effect. The analysis of the determinants of abnormal returns following debt announcements shows a positive impact of financial development and a negative effect of the Eurozone crisis.
Document de travail DT / 116 / 2005 Too much consensus could be harmful : measuring the degree of implementation of the Washington consensus and its impact on economic growth par

In this paper, we construct a unique quantitative measure of the depth and pace of all aspects of IFI programs — the Washington consensus index (WCI) —, and we investigate their whole impact on economic growth. Two main conclusions emerge. Firstly, among observed countries, those who come up to Consensus expectations maintain a relatively high degree of government involvement. Secondly, when combined with usual explanatory variables, WCI presents a significant non-linear relation with the probability of getting a higher growth than others get. Thus, it seems that a “too fast” and/or a “too far” implementation of IFI programs, especially in regard of deregulation and monetary orthodoxy, can harm growth in developing countries.

Neutron powder diffraction study of a system of half-hole-doped bismuth-based calcium manganites at room temperature

The structural effects of partial replacement of diamagnetic Bi3+ for potential charge ordering and magnetic ordering phenomena in Bi0.25R0. 25Ca0.5MnO3 (R = La, Nd, Ho) have been studied. The analysis of the room-temperature data suggests that in bismuth-based calcium perovskites the lone pair character of 6s2 Bi3+ orbitals is constrained rather than dominant. At 10 K the ground magnetic state of all compounds was specified as CE-type antiferromagnetic.

Due to globalization, advancing technology, increasing competition, and new management techniques; organizations have been getting changed and as a consequence the structures of them have become more complex. With this change in the organizational structure, work specialization has increased and employees have been alienated with their job. Long-term job guarantee and stable employment structure that characterize 20th century have been changed. Nowadays’ uncertainties cause employee and employer expectations become uncertain. These uncertainties are filled with the psychological contracts which have significant impact on the written and oral contracts. Organizational deviance behaviors, the intentional behaviors that aim to damage the organization or its members, occur in reaction to employee experiences and have determinants such as disappointment and inequity perception. In this study, it’s been argued that the perceived type of psychological contract by the employee has an impact on the organizational deviance. The data collected from 510 sales representatives in the pharmaceutical industry has been analyzed using multiple regression. According to the study results, it has been found a direct positive relation between psychological contract and organizational deviance.
Assessing Electric Vehicles Battery Second Life Remanufacture and Management

Electric cars are entering into the automotive market. However, their prices are still expensive mostly due to the battery cost. Additionally, electric vehicle batteries are considered not useful for traction purposes after they have lost a 20% of its capacity. Having still an 80% of its capacity, these batteries may work on stationary applications with lower requirements than electric mobility. In order to recover part of the battery costs came out the idea of giving batteries a second life. Nonetheless, before its reuse, these batteries should follow a transformation process that, although valuable, it is not simple. They should be collected, checked and adapted, if necessary, to their new application requirements. Nowadays, each car manufacturer has its own battery partner using a particular cell shape and chemistry. Additionally, each battery has different module configurations and electronic control parameters and equipment. Moreover, each battery model has a particular refrigeration system in the final packaging that forms the whole battery. All these aspects put the reusability of electric vehicle batteries into a narrow path where a bad step could lead to business collapse. This study shows some of the difficulties and issues that should be taken into account when managing second life battery businesses.
A new golden era in island biogeography

For two centuries, islands have served as rich sources of inspiration and data for biogeographers, thus gaining renown as ideal natural laboratories. Their research potential continues to expand today thanks to the combined application of recent advances in several scientific fields. First, increasingly detailed geological and palaeoecological data are extending our understanding of the history of development of island biotas. At the same time, rapid methodological advances in molecular evolutionary biology and systematics are revealing the pathways by which species colonized islands, evolved, and formed communities. Third, basic data on species distributions are being collected from increasing numbers of islands and taxa, distributed widely through electronic resources, and analyzed with powerful software to reveal macroecological patterns. The pace and quality of recent advances signal a promising future in which islands will continue to play key roles in revealing how biodiversity is produced and maintained.
Managing the academic talent void: Investigating factors in academic turnover and retention in South Africa

Orientation: Globally, the demand for academic staff in higher education is expected to continue to increase. The South African situation is exacerbated by the so-called ‘retirement swell’ and turnover and retention problems; measurements to diagnose these factors remain limited. Research purpose: This study aimed to investigate the factors that influence turnover and retention of academic and to validate the developed talent retention diagnostic tool for use in South African higher education institutions. Motivation for the study: Limited research currently exists on the retention factors of academic staff in the South African context. Research approach, design and method: Using an investigative quantitative research approach, the tool was administered to a convenience sample of academics ( n = 153) in 13 higher education institutions. Main findings: The results showed an array of distinguishing turnover and retention factors and proved the tool to be a valid and reliable measure. Over half the respondents indicated slight to strong dissatisfaction with compensation and performance management practices. Significantly, 34% indicated that they considered exiting their academic institution, citing unhappiness about compensation, as the most likely reason, whilst 74.5% have previously looked for another job. Practical/managerial implications: The research highlights key areas (i.e. compensation, emotional recognition, a bonus structure that reflects employee contribution, performance management systems, mentorship and career development opportunities) that higher education should attend to if they want to retain their key and talented academic staff. Contribution/value-add: The results contribute to new knowledge on the factors that contribute to turnover and retention of academic staff and present a valid and reliable measure to assess these retention factors.
Starbursts Triggered by Central Overpressure. II. A Parameter Study

A parameter study is made of the radiative shock compression of a disk molecular cloud due to the high pressure of the central molecular intercloud medium, after the cloud has fallen into the central region of a galaxy following a galaxy interaction. The dependence of the compression on the disk cloud and central gas parameters has been studied. We show that fshell, the fraction of cloud mass compressed in the outer shell that becomes unstable, is a function of only the external pressure, the cloud radius, and the cloud density. We find that for a wide range of values for the input parameters, fshell is high and lies between 0.75 to 0.90. The fraction fshell is not sensitively dependent on the value of the central gas pressure because the initial inward shock velocity is proportional to the square root of the central pressure, and at later stages it is determined mainly by the self-gravity of the shocked shell. Thus, star formation triggered in disk clouds by compression by the central overpressure, as proposed by Jog & Das, is a general triggering mechanism and is valid as long as the central gas has an overpressure of even a factor of a few higher than that of the incoming disk molecular clouds.We apply the mechanism to the galaxies for which the central gas parameters are known; for example, IC 342 and NGC 1808. We find that in both cases a large fraction of the cloud mass will be compressed. Hence, these galaxies should show a central starburst, provided that there is a substantial gas infall rate from the disk to the central region. This agrees with observations, in that NGC 1808 with gas infall due to galaxy interaction has a central starburst, while IC 342 does not.
