Quantile Regression Coefficients Modeling : a Penalized Approach

Modeling quantile regression coefficients functions permits describing the coefficients of a quantile regression model as parametric functions of the order of the quantile. This approach has numerous advantages over standard quantile regression, in which different quantiles are estimated one at the time: it facilitates estimation and inference, improves the interpretation of the results, and is statistically efficient. On the other hand, it poses new challenges in terms of model selection. We describe a penalized approach that can be used to identify a parsimonious model that can fit the data well. We describe the method, and analyze the dataset that motivated the present paper. The proposed approach is implemented in the qrcmNP package in R. Abstract I coefficienti di una regressione quantilica sono funzioni iniettive dell’ordine del quantile. L’approccio standard è quello di stimare i quantili uno alla volta. Un metodo alternativo è quello di esprimere la forma funzionale dei coefficienti usando un modello parametrico. Questo approccio ha numerosi vantaggi: semplifica le procedure di stima e inferenza, migliora l’interpretazione dei risultati, e risulta statisticamente efficiente. Al tempo stesso, pone nuove sfide in termini di selezione del modello. La nostra proposta è quella di usare un metodo penalizzato che permetta di identificare un modello parsimonioso che rappresenti correttamente la funzione quantilica. In questo articolo descriviamo il metodo, e analizziamo il dataset che ha motivato il lavoro. L’approccio proposto è stato implementato nel pacchetto R qrcmNP.

Interleukin-8 as a Surrogate Marker in Risk Stratification of Patients with Acute Myeloid Leukemia

Introduction: When molecular and cytogenetic studies are not available, the risk stratification of AML patients will be difficult. This study was conducted to evaluate the prognostic value of IL-8 among AML patients with its relation to outcome. Methods: This is a cross sectional study; 42 newly diagnosed AML patients (<65 years) were investigated with determination of serum IL-8 by ELISA and followed up for 36 months. In addition, 20 sex and age matched normal volunteers were included as control. Results: In AML patients, serum IL-8 was ranging from 5 to 200 pg/mL with a mean of 76.5 pg/mL. It was significantly higher among AML patients when compared to the control (76.5 vs 32.3 pg/mL). The mean did not show any significant relationship to patients’ sex or the FAB classification of AML (p>0.05). While significant higher mean was observed among poor cytogenetic risk group (110.4 pg/mL) as well as among died patients (108.8 pg/mL) and refractory patients (84.2 pg/mL). In regard to survival, among those with IL-8>40 pg/mL, the mean survival time was higher in comparison to AML patients with IL-8 ≤ 40 pg/mL (34.6 months vs 26.3 months). Conclusion: This study concluded that serum IL-8 concentration at presentation of AML patients is high and it could be used as a marker for risk stratification for AML patients.
Unemployment , and Welfare with Risk Averse Workers

This paper studies the welfare and policy implications of o¤shoring when risk averse workers face the risk of unemployment. If o¤shored inputs can be easily substituted for domestic workers, then o¤shoring reduces wages and increases unemployment. In this situation, in the absence of any government intervention o¤shoring not only reduces the welfare of workers but could reduce aggregate welfare as well if workers are highly risk averse and the markets for insurance against unemployment risk are missing. In addition to unemployment insurance, the role of employment protection policiesseverance payments and administrative cost of ring -in protecting workers against the adverse consequences of globalization is studied. An administrative cost of ring reduces job destruction, however it ends up reducing the welfare of workers. Mandated severance payments and unemployment insurance can both protect workers against the adverse e¤ects of o¤shoring and have the potential to make o¤shoring aggregate welfare improving. When unemployment arises due to both job destruction and matching frictions, a combination of severance payments and unemployment bene ts is a better policy to shield workers from the adverse consequences of o¤shoring than either of them alone. Keywords: o¤shoring, unemployment, endogenous job destruction, severance payments, unemployment bene ts JEL Codes: F16, F66, F68

ATRIAL ELECTRICAL AND MECHANICAL DYSFUNCTION IN NON-DIABETIC , NON-HYPERTENSIVE HEMODIALYSIS PATIENTS

Background: Abnormalities in atrial conduction times and mechanical functions are considered as independent predictors of atrial fibrillation. However, there is no data in literature about functional parameters and electromechanical delay intervals in nondiabetic, non-hypertensive hemodialysis (HD) patients. We aimed to study atrial electromechanical conduction times and mechanical functions in this population. Methods: Forty-two non-diabetic, normotensive hemodialysis patients and age and sex matched control subjects have been enrolled in the study. Standard and Tissue Doppler Echocardiography have been performed before mid-week dialysis session for HD group and on admission for control group. Results: PAlateral, PAseptum durations of the hemodialysis group were significantly longer than control group (70.6±9.1 vs 55.3±2.7, 50.8±5.2 vs 44.4±2.1; p<0.01). Interatrial and left-right intraatrial electromechanical delay intervals were significantly longer in hemodialysis group compared to controls (31.6±7.2 vs 18.0±2.6, 19.8±7.9 vs 10.9±2.7, 11.8±5.1 vs 7.1±1.2, respectively; all p<0.01). Measurements of left atrial diameter, maximum, minimum and before atrial systole, volumes and passive-active emptying volumes were both elevated in hemodialysis group compared to controls (all p<0.01). Conclusions: This is the first study enlightening deterioration in atrial mechanical and electromechanical functions in nondiabetic, non-hypertensive HD population. Results of the present study reflect not only negative effects of structural remodeling, which has been mentioned in previous studies in literature, but also negative effects of electrical remodeling. Prolonged interand intra-atrial electromechanical delay intervals should be the underlying pathophysiological factors increasing the rate of atrial fibrillation in hemodialysis population.
Conception of an E-Learning Scheme at the University of Algarve

With the proliferation of the Internet use, a growth of e-learning courses has been verified. We arrived to the moment where it is not enough for Universities to have standard courses to offer to the students, because there is an increasing population which tends to choose his formation according to their objectives, styles, needs and learning preferences (the student profile). This way, the universities are faced with a new challenge, which is to offer, together with the standard courses, modules specially tailored to the user desires, based on the identification of the customers needs. In this paper, a model for the distance formation through Internet is discussed, that is being developed in the University of Algarve, which makes possible each individual to learn in agreement with his/her profile.
FLOW CONTROL – PRELIMINARY DESIGN OF SYNTHETIC JET ACTUATOR

Synthetic jet alternating blowing and suction is a well-known shear layer active flow control technique. By means of the synthetic jet is possible to lower drag, to increase lift or to intensify heat transfer in wide range of different applications like airplanes, cars, compressors, turbines, etc. One of the first who showed that turbulent boundary layer separation can be controlled by alternating blowing and suction was Seifert et al. (1993). Chen et al. (1999) focused on the increase of mixing and Smith & Glezer (2002) demonstrated the possibility to use synthetic jet for jet vectoring. An important advantage of the synthetic jet, comparing to a conventional blowing or suction, is a significantly lower value of the supplied momentum needed for the same effect, Seifert et al. (1993). The efficiency of the flow control by means of a synthetic jet depends on a correct design of the synthetic jet generator. The design of the synthetic jet generator must be made regarding the character of the flow field. The frequency of the synthetic jet should correspond to the natural vortex shedding frequency to influence separation or mixing process in the right way. This can be described like a change of the rate of vortex structures splicing. Several approaches can be used to influence the rate of vortex’s structures splicing by synthetic jet. The first case is when the exciting frequency of the jet corresponds to the natural vortex shedding frequency. Another possibility is the application of high frequency synthetic jet with amplitude modulation, Matejka et al. (2009). Amplitude modulation is used to generate lower frequencies, which agrees with the natural vortex shedding frequency. Many authors used exciting frequency of the synthetic jet much higher comparing to frequency of the natural vortex shedding frequency. This case was explained by Dandois et al. (2007). The synthetic jet is creating vortex structures. These vortex structures originate due to the interaction of the boundary layer (main flow) with pulsating stream from output orifice of the synthetic jet generator. The flow control should be done with minimum input power, so the synthetic jet generator should be operated on its resonant frequency. In case of resonant frequency the velocity of the synthetic jet is maximized. Preliminary design of the synthetic jet can be done using Lumped Element Modeling (LEM), Gallas et al. (2002). LEM is based on analogy between electrical and acoustic domain, which corresponds to the synthetic jet actuator. The main assumption of LEM is that the characteristic length scales of the governing physical phenomena are larger than the geometric dimension. In this case the acoustic wavelength must be much greater than the size of the synthetic jet generator.
An Activity Theory Approach to Mediating the Development of Metacognitive Norms During Problem Solving

Metacognition has long been identified as an essential component of the problem-solving process. Research on metacognition and metacognitive training has historically adopted an acquisitionist view. This study takes a participaionist lens by considering metacognition as a habit of mind or dispositional tendency. Problem-solving habits of mind can be viewed as normative ways of thinking to which students become attuned by participating in authentic problem-solving situations. This study explored one such situation, in which portfolio problemsolving sessions and write-ups were used to mediate metacognitive thinking. Periodically, students worked together on non-routine problems and submitted individual write-ups documenting their judgement and decision-making processes. Analysis utilized Activity Theory, which operationalizes the participation structure of a classroom, to document the nonlinear development of classroom metacognitive norms during problem solving. Micro-analysis revealed a shift from productto process-oriented metacognitive norms. Macro-analysis situated these results, highlighting social mediators of activity and contradictions as catalysts for change.

, N 90-298 8 A Design Strategy for Autonomous Systems

This paper identifies and puts forward some solutions to crucial issues regarding the competent performance of an autonomously operating robot, namely that of handling multiple and variable data sources containing overlapping information and maintaining coherent operation whilst responding adequately to changes in the environment. Support for the ideas developed for the construction of such behaviour are extracted from speculations in the study of cognitive psychology, an understanding of the behaviour of controlled mechanisms and the development of 'behaviour-based' robots in a few robot research laboratories. The validity of the ideas expressed is supported by some simple simulation experiments in the field of mobile robot navigation and guidance. 403 https://ntrs.nasa. gov/search.jsp?

“ Factors affecting Brand loyalty of Apple iPhone in Pakistan ”

The Apple iPhone brought a whole new level on interface and features such as incorporating the iPod technology as well as multi-touch technology which let users to control everything using only their fingers. The research on the level of customer loyalty/satisfaction on buying an iPhone has been done across the world as it was one of the first hand phones that were release by Apple. Customer satisfaction is a blurred and concrete concept and the actual expression of the state of satisfaction will vary depending on individual's needs and it also depends on the product or service. The level of loyalty/satisfaction can also vary depending on other options the customer may have and other products against which the customer can compare the organization's products. It also distinguishes six qualities of attributes such as basic factors, excitement factors, performance factors, indifferent attributes, questionable attributes and reverse attributes. The objective of this research is to analyze the level of loyalty/satisfaction of having an iPhone based on certain factors. This research will look into factors such as price and quality where each factors has its respective advantages or disadvantages to affect the customer's level of loyalty/satisfaction. This is because every diverse consumer has their own priority of need before even getting a new hand phone. The research will be focusing on the capability of the iPhone and what it has to offer to the customers that makes it different and better than its competitors. These capabilities refer back to the factors which were mentioned earlier in the paragraph earlier. Technology for hand phones has been developing endlessly with new features offered as time passed. Apple's new range of products, especially the iPhone shows such vast improvement. The research first looks at the background of the company which is Apple and what they have offered to their customers before launching the iPhone. Next, the research will provide detailed explanation and information on each factor that will affect the customer's brand loyalty. The research will use only primary data such as online journals and articles, blogs and newspapers so that the latest information can be obtained for the research.

Motor Vehicle Safety : An Update for Emergency Medicine Practitioners

Introduction Motor vehicle crashes are a significant burden to health in the United States1 and worldwide. Worldwide road traffic injuries disable 20-50 million persons each year with almost 1.2 million being fatally injured.2 WHO predicts this burden will increase significantly in the next ten years especially in low-income and middle-income countries.2 In 2006, there were nearly 6 million police reported motor vehicle crashes in the US with 1.75 million of these crashes resulting in injury.3 Of the more than 2.6 million people injured in these crashes, 42,642 were fatal injury victims.3 Previous estimates using 2000 data suggested that the cost of motor crashes is in excess of 230 billion dollars or 2.3 percent of the US gross national product.4
