Estimation of the mincerian wage model addressing its specification and different econometric issues

In the present doctoral thesis, we estimated Mincer’s (1974) semi logarithmic wage function for the French and Pakistani labour force data. This model is considered as a standard tool in order to estimate the relationship between earnings/wages and different contributory factors. Despite of its vide and extensive use, simple estimation of the Mincerian model is biased because of different econometric problems. The main sources of bias noted in the literature are endogeneity of schooling, measurement error, and sample selectivity. We have tackled the endogeneity and measurement error biases via instrumental variables two stage least squares approach for which we have proposed two new instrumental variables. The first instrumental variable is defined as "the average years of schooling in the family of the concerned individual" and the second instrumental variable is defined as "the average years of schooling in the country, of particular age group, of particular gender, at the particular time when an individual had joined the labour force". Schooling is found to be endogenous for the both countries. Comparing two said instruments we have selected second instrument to be more appropriate. We have applied the Heckman (1979) two-step procedure to eliminate possible sample selection bias which found to be significantly positive for the both countries which means that in the both countries, people who decided not to participate in labour force as wage worker would have earned less than participants if they had decided to work as wage earner. We have estimated a specification that tackled endogeneity and sample selectivity problems together as we found in respect to present literature relative scarcity of such studies all over the globe in general and absence of such studies for France and Pakistan, in particular. Differences in coefficients proved worth of such specification. We have also estimated model semi-parametrically, but contrary to general norm in the context of the Mincerian model, our semi-parametric estimation contained non-parametric component from first-stage schooling equation instead of non-parametric component from selection equation. For both countries, we have found parametric model to be more appropriate. We found errors to be heteroscedastic for the data from both countries and then applied adaptive estimation to control adverse effects of heteroscedasticity. Comparing simple and adaptive estimations, we prefer adaptive specification of parametric model for both countries. Finally, we have applied quantile regression on the selected model from mean regression. Quantile regression exposed that different explanatory factors influence differently in different parts of the wage distribution of the two countries. For both Pakistan and France, it would be the first study that corrected both sample selectivity and endogeneity in single specification in quantile regression framework

Combined Acquisition Technique (CAT) for Neuroimaging of Multiple Sclerosis at Low Specific Absorption Rates (SAR)

Purpose To compare a novel combined acquisition technique (CAT) of turbo-spin-echo (TSE) and echo-planar-imaging (EPI) with conventional TSE. CAT reduces the electromagnetic energy load transmitted for spin excitation. This radiofrequency (RF) burden is limited by the specific absorption rate (SAR) for patient safety. SAR limits restrict high-field MRI applications, in particular. Material and Methods The study was approved by the local Medical Ethics Committee. Written informed consent was obtained from all participants. T2- and PD-weighted brain images of n = 40 Multiple Sclerosis (MS) patients were acquired by CAT and TSE at 3 Tesla. Lesions were recorded by two blinded, board-certificated neuroradiologists. Diagnostic equivalence of CAT and TSE to detect MS lesions was evaluated along with their SAR, sound pressure level (SPL) and sensations of acoustic noise, heating, vibration and peripheral nerve stimulation. Results Every MS lesion revealed on TSE was detected by CAT according to both raters (Cohen’s kappa of within-rater/across-CAT/TSE lesion detection κCAT = 1.00, at an inter-rater lesion detection agreement of κLES = 0.82). CAT reduced the SAR burden significantly compared to TSE (p<0.001). Mean SAR differences between TSE and CAT were 29.0 (±5.7) % for the T2-contrast and 32.7 (±21.9) % for the PD-contrast (expressed as percentages of the effective SAR limit of 3.2 W/kg for head examinations). Average SPL of CAT was no louder than during TSE. Sensations of CAT- vs. TSE-induced heating, noise and scanning vibrations did not differ. Conclusion T2−/PD-CAT is diagnostically equivalent to TSE for MS lesion detection yet substantially reduces the RF exposure. Such SAR reduction facilitates high-field MRI applications at 3 Tesla or above and corresponding protocol standardizations but CAT can also be used to scan faster, at higher resolution or with more slices. According to our data, CAT is no more uncomfortable than TSE scanning.
Predicting Continuing Acceptance of IT in Conditions of Sporadic Use

This paper tests a new predictive model of IT acceptance in conditions where use is characteristically sporadic. The model utilizes cognitive constructs from the well-known technology acceptance model (TAM) [8] in combination with habit and a new construct measuring perceived regularity of use. Initial tests indicate that the model explains several important effects of regularity and predicts substantially more of the variance in continuing acceptance than alternative models.
Semi-supervised object recognition using flickr images

In this work we present an algorithm for extracting region level annotations from flickr images using a small set of manually labelled regions to guide the selection process. More specifically, we construct a set of flickr images that focuses on a certain concept and apply a novel graph based clustering algorithm on their regions. Then, we select the cluster or clusters that correspond to the examined concept guided by the manually labelled data. Experimental results show that although the obtained regions are of lower quality compared to the manually labelled regions, the gain in effort compensates for the loss in performance.
tudy of the origin of short-and long-latency SSEP during recovery from brain schemia in a rat model an Wua

Somatosensory evoked potentials (SSEPs) have been established as an electrophysiological tool for the prognostication of neurological outcome in patients with hypoxic–ischemic brain injury. The early and late responses in SSEPs reflect the sequential activation of neural structures along the somatosensory pathway. This study reports that the SSEP can be separated into early (short-latency, SL) and late (longlatency, LL) responses using independent component analysis (ICA), based on the assumption that these components are generated from different neural sources. Moreover, this source separation into the SL
Human Colon Cancer HCT 116 Cells

An association between the resistance to mitomycin C (MMC) and a decrease of NAD(P)H:quinone oxidoreductase (NQO1) activity was re ported for a MMC-resistant subline, HCT 116-R3OA,derived from MMC sensitive HCT 116 cells. Eight NQO1 cDNA clones were IsOlated from these two sublines by reverse transcription-PCR. Two clones, pDT9 from HCT 116 and pDT2Ofrom HCT 116-R3OA,are the full length of 274 amino acids. These two clones differ by a T to C substitution at nucleotide 464, whIch results in a replacement of aa-ginine 139 by tryptophan in the enzyme. NQO1 of pDT9 and pDT2O was expressed in Escherichia coli, purified, and shown to have a protein subunit OfMr 30'000, The change of amino acid 139 resulted In a shift of isoelectric pH from 9.5 to &35 and a 60% decrease of activity in reducing MMC. All of the other six clones differ from pDT9 by a deletion of exon 4. On Northern blot, we detected two mRNA species of NQO1 (1.2 and 2.7 kilobases) due to alternative polyadenylation in all sublines. MMC resistant sublines showed 75â€”90% mRNA expression relative to HCT 116 cells. Reverse transcription-PCR amplification of eDNA fragment of nucleotide 298â€”617revealed two full-length mRNAs in HCT 116 cells but only one full-length mRNA in HCT 116-R3OAcells. An exon 4 deletion mRNA was detected In both sublines. The two full-length mRNAs may be from either alleles or chimeras of the same gene and the exon 4 deletion mRNA is a result of alternative splicing. On Western blot, we detected only one M@30,000 protein in all sublines. A substantial decrease of this protein in MMC-resistant sublines (5% of HCT 116) explained the 95% decrease of their NQO1 activity. Tran scriptional regulation and posttranscriptional modification may be responsible for the disparity of gene expression of NQO1 and the low concentration of NQO1 protein in MMC-resistant sublines. Reversal of MMC resistance and the recovery of NQO1 in two revertants further supports the hypothesis that cellular control of NQO1 can modulate the cytotoxicity of MMC.
System performance of LTE and IEEE 802.11 coexisting on a shared frequency band

This paper presents the system performance analysis of 3GPP Long-Term Evolution (LTE) and IEEE 802.11 Wireless Local Area Networks (WLAN) in a situation where LTE downlink (DL) has been expanded over to unlicensed frequency band usually used by WLAN. Simple fractional bandwidth sharing mechanism is used to allow both technologies to transmit. The system performance is evaluated by means of fully dynamic network simulations.
Genetic Divergences and Phylogenetic Relationships Among the Fejervarya limnocharis Complex in Thailand and Neighboring Countries Revealed by Mitochondrial and Nuclear Genes

Abstract To clarify the genetic divergence in the F. limnocharis complex from Thailand and neighboring countries and to elucidate the phylogenetic problems of this taxon, we analyzed partial sequences of the mitochondrial 12S and 16S rRNA genes and the nuclear CXCR4, NCX1, RAG-1, and tyrosinase genes. The F. limnocharis complex from Thailand had three distinct haplotypes for 12S and 16S rRNA genes. Nucleotide similarities and the phylogenetic relationships indicated that the haplotype 1 group corresponded to the real “F. limnocharis”, the haplotype 2 group was F. orissaensis or closely related to it, and the haplotype 3 group was possibly an undescribed species. Mitochondrial gene data also showed two major clades of the genus Fejervarya, the Southeastern and South Asian groups. Although F. orissaensis is so far known only from Orissa in India, the haplotype 2 group was observed in Thailand. This distribution pattern and the phylogeny suggested that the origin of F. orissaensis and the haplotype 2 group might lie in Southeast Asia. There was also evidence suggesting that the haplotype 3 group originated in the South Asian area and has spread to northern Thailand. The nuclear gene data did not support the monophyly of the haplotypes recognized by mitochondrial genes. This incongruence between the mitochondrial and nuclear data seems to be caused by ancestral polymorphic sites contained in nuclear genes. Although neither the mitochondrial nor the nuclear data clarified intergeneric relationships, the nuclear data rejected the monophyly of the genus Fejervarya.
Performance analysis and cooperation mode switch in HARQ-based relaying

We study the optimal, in terms of power-limited outage probability (OP), placement of the relay and investigate the effect of relay placement on the optimal cooperation mode of the source and the relay nodes. Using hybrid automatic repeat request (HARQ) based relaying techniques, general expressions for the OP and the average transmit power are derived. The results are then particularized to the repetition time diversity (RTD) protocol. The analytical expressions are used to find the transmit powers minimizing the power-limited OP. Our results demonstrate that adaptive power allocation reduces the OP significantly. For instance, consider a Rayleigh fading channel, an OP of 10 3 and a maximum of 2 RTD-based retransmissions. Then, compared to equal power allocation, the required transmission signal-to-noise ratio (SNR) is reduced by 5 dB, if adaptive power allocation is utilized. Moreover, depending on the relay positions and the total power budget, the system should switch between the single-node transmission mode and the joint transmission mode, in order to minimize the outage probability.

From Security Modelling to Run-time Security Monitoring

In this paper we take the first steps from security modelling to runtime security monitoring. Providing full support for run-time security monitoring requires that following issues are solved: security concepts has to be defined in an unambiguous way, security level has to be defined and measured, and finally, software has to adapt itself based on measurements and requirements. This paper addresses the unambiguous definition of security by examining existing security ontologies. None of the existing ontologies is able to support run-time security monitoring as such, and there is a need to combine and widen these ontologies. In addition, this paper describes our vision how run-time security management can be achieved as the wholeness.
UMCC_DLSI-(SA): Using a ranking algorithm and informal features to solve Sentiment Analysis in Twitter

In this paper, we describe the development and performance of the supervised system UMCC_DLSI-(SA). This system uses corpora where phrases are annotated as Positive, Negative, Objective, and Neutral, to achieve new sentiment resources involving word dictionaries with their associated polarity. As a result, new sentiment inventories are obtained and applied in conjunction with detected informal patterns, to tackle the challenges posted in Task 2b of the Semeval2013 competition. Assessing the effectiveness of our application in sentiment classification, we obtained a 69% F-Measure for neutral and an average of 43% F-Measure for positive and negative using Tweets and SMS messages.
A Comparison of Death Anxiety, Intolerance of Uncertainty and Self-Esteem as Predictors of Social Anxiety Symptoms

Abstract This study sought to examine the role of death anxiety as a transdiagnostic predictor of social anxiety symptomatology compared to self-esteem and intolerance of uncertainty, and to examine the relationship between measures of intrinsic and extrinsic religiosity and death anxiety. A total of 591 participants, 445 females, average age 38.0 years (SD = 14.5), completed an online survey including background questions, the Depression, Anxiety and Stress Scale, the Social Interaction Anxiety and Social Phobia Scale, the Rosenberg Self-Esteem Scale, the Intolerance of Uncertainty Scale, the Santa Clara Strength of Religious Faith Questionnaire, the Spirituality Scale, and the Death Anxiety Scale. No significant, independent relationship was found between death anxiety and social anxiety symptomatology, although self-esteem and intolerance of uncertainty were significant predictors of both measures of social anxiety, confirming the importance of these key transdiagnostic mediators as predictors of social anxiety symptomatology. A strong negative correlation was found between death anxiety and measures of both intrinsic and extrinsic religiosity in this general population sample not selected for high religious affiliation.
#FIVE : High-level components for developing collaborative and interactive virtual environments

This paper presents #FIVE (Framework for Interactive Virtual Environments), a framework for the development of interactive and collaborative virtual environments. #FIVE has been developed to answer the need for an easier and a faster conception and development of virtual reality applications. It has been designed with a constant focus on re-usability with as few hypothesis as possible on the final application in which it could be used. Whatever the chosen implementation for the Virtual Environment (VE), #FIVE : (1) provides a toolkit that eases the declaration of possible actions and behaviours of objects in the VE, (2) provides a toolkit that facilitates the setting and the management of collaborative interactions in a VE, (3) is compliant with distribution of the VE on different set-ups and (4) proposes guidelines to efficiently create a collaborative and interactive VE. It is composed of several modules, among them, two core modules : the relation engine and the collaborative interaction engine. On the one hand, the relation engine manages the relations between the objects of the environment. On the other hand, the collaborative interaction engine manages how users can collaboratively control objects. The modules that compose the #FIVE framework can be used either independently or simultaneously, depending on the requirements of the application. They can also communicate and work with other modules thanks to an API. For instance, a scenario engine can be plugged to any or both of the #FIVE modules if the application is scenario-based. #FIVE is a work in progress, new core modules will later be proposed. Nevertheless, it has already been used in some VR applications by several persons in our lab. The feedbacks we obtained are rather positive and we intent to further develop #FIVE with additional functionalities, notably by extending it to the control of avatars whether they are controlled by a user or by the system.
Biodegradability and Biocompatibility Study of Poly(Chitosan-g-lactic Acid) Scaffolds

A biodegradable, biocompatible poly(chitosan-g-lactic acid) (PCLA) scaffold was prepared and evaluated in vitro and in vivo. The PCLA scaffold was obtained by grafting lactic acid (LA) onto the amino groups on chitosan (CS) without a catalyst. The PCLA scaffolds were characterized by Fourier Transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). The biodegradabilty was determined by mass loss in vitro, and degradation in vivo as a function of feed ratio of LA/CS. Bone marrow mesenchymal stem cell (BMSC) culture experiments and histological examination were performed to evaluate the PCLA scaffolds’ biocompatibility. The results indicated that PCLA was promising for tissue engineering application.
Maximum entropy feature fusion

We review recent theoretical results in maximum entropy (MaxEnt) PDF projection that provide a theoretical framework for fusing the information from multiple features for the purpose of general statistical inference. Given a high-dimensional input data vector x, and several dimension-reducing feature transformations zi = Ti(x), we consider the problem of estimating the probability density function (PDF) of x by fusing the information in the various features. When the PDF of one feature p(zi) is known or has been estimated, the PDF pi(x) that has maximum entropy among all PDFs consistent with p(zi) can be constructed. This is called the maximum entropy projected PDFs and can serve as a generative models from which random samples can be drawn. The information from all the features can be fused into a common classifier structure either by testing each hypothesis with a different feature, or by combining the various projected PDFs in a mixture PDFs. We review related theoretical and experimental results and provide a simulated classification experiment to highlight the potential of the method.
Advanced Radio Resource Management for IMT-Advanced in WINNER+ (II)

Two main draft standards were submitted in October 2009 as candidate technologies for IMT-Advanced, namely IEEE 802.16m and 3GPP LTE-Advanced. However, several details on their functionalities are still open and the research community is racing towards the complete definition of the revolutionary next fourth generation mobile, 4G. In this framework the European Celtic project WINNER+ is bridging together experts from industry, academia and government all around Europe to devise these 4G technologies.
