APOYO PARENTAL Y SU INCIDENCIA EN EL DESARROLLO DE ESTRATEGIAS DE APRENDIZAJE EN EDUCACIÓN SECUNDARIA: UN ESTUDIO EXPLORATORIO PARENTAL SUPPORT AND ITS EFFECT ON THE DEVELOPMENT OF LEARNING STRATEGIES IN SECONDARY SCHOOL: AN EXPLORATORY STUDY

This paper focuses on examine the impact that parental support has about the learning strate- gies in their children. To this end, it was applied the Learning Strategies Questionnaire (CEA) to a total of 80 students of 1 st and 4 th grade of Secondary School, from three centers -privates and publics- located in Lugo. Forty of them received parental support regularly in their academic tasks. The rest of them didnt have any help of this type. For the statistical analysis we used the SPSS 15.0 program. Our results indicate that the students -in general- show an adequate level in the use of learning strategies, without registering significative differences according to the parental support. However, there have been found differences on the organization (p<.010) and regulation (p<.050) subscales, obtaining the students that have the help of their parents on the realization of the aca- demic tasks higher scores than those who dont have it. Likewise, there were found differences on the metacognition scale (p<.050). Specifically, in the case of the students -males- of the 1 st grade, where the students that had parental support marked significantly higher than their homologous in that scale. Moreover, there were found differences according to the gender among those students that received parental support, showing males better emotional control than females (p<.050).
Oral Testing and Self-Assessment - The Way Forward?

Traditional methods of testing which still prevail in Korea mean that there is very little time for Conversational English in the test-driven secondary classroom, despite introduction of recent advances in language teaching methodology. This paper suggests that the use of English can only be promoted in schools by incorporating an "Oral Test" into the overall testing requirements, and that self assessment by students of those tests can be a valuable additional means of improving oral abilities. A test was developed focusing on the improvement in spoken English of 1700 Freshman University students over an academic year (64 hours). This was administered and evaluated using established oral-test criteria. Grading was relative, looking at improvement rather than level of achievement, and the Conversation-English course taken by the students was the basis of the test. Results showed that: i) preparation for the test necessitated active spoken participation in lessons; ii) lessons tended to utilize task-based communicative teaching methods; iii) the means became the end the test was not only a reason for developing oral skills, but also a means of achieving that goal.
The Impact of Financial Structure on Poverty Reduction : A Study using Household Data from Peru , 1985-2000 *

This paper estimates/calibrates a growth model with endogenous financial structure using household data from Peru. The idea is to feature the role of fin ancial infrastructure in generating GDP growth and increasing inequality as observed in Peru during the 1990’s through the lens of an economic model of households’ saving/investment decisions. The ty pical approach to estimate the contribution of financial sector expansion to GDP growth is t o run simple cross-country regression based on stationary relationship among variables. Thi s paper takes an alternative approach that has two main contributions. First, actual data is t hought of as a transitional phenomenon – whole history is considered as one sample – which allows s tudying whether the simulated economy with specific shocks can generate the same time paths of actual aggregate data. The analysis provides implications for the evolution of incom e inequality and its interaction with financial development. Second, the paper provides a benchmark to investigate whether observed levels and rates of financial expansion have been adequa te. Provided that government and private sector resources are limited, quick expansion ma y not be possible or desirable. The approach in the paper explicitly solves the household’s saving/inve stment problem and, by employing historical data, offers a benchmark for financial expa nsion consistent with observed time path of GDP growth. In the artificial, simplified model, house holds accumulate savings to pay a fixed cost to participate in the formal financial secto r and, thus, to benefit from higher return and insurance against idiosyncratic shocks. Investme nt technology parameters are estimated from household data and the aggregate paths of the econom y are calibrated to actual GDP growth. When I compare “actual” and “model-predicted” time paths I find that the benchmark economy largely overestimates actual financial par tici tion in Peru during the period 1985-2000, 19% vs. 7%. To a great extent, this over prediction seems explained by the signifi cant reduction in the number of households saving in formal financial insti tutions observed in the household data (26% to 10%). Observed increasing inequality is als o predicted in the calibrated economy, but, in the model, the large welfare costs from “restr icted” financial participation affect more middle-wealth groups rather than the poor. The findings in the p ap r suggest that there are large welfare gains from expanding (or recovering past) formal financi al participation levels. * An Application to the Case of Peru of “Financial D eepening, Inequality and Growth: A Model Driven Quantitative Evaluation” by Robert M. Townsend and Kenichi Ueda (2001). † The bulk of the analysis in my paper was carried o ut in the last year of my graduate studies at the University of Chicago, with the guidance and collab oration of Professor Robert M.

Optimal trajectory tracking for missiles with Doppler Beam Sharpening radars

This paper investigates optimal trajectory tracking for missiles fitted with Doppler Beam Sharpening seekers, which are used to generate a radar image of the terrain. The guidance problem for this type of sensor is complex as constraints must be imposed on the flight path of the missile to ensure the seeker can obtain adequate crossrange resolution for target recognition and aimpoint selection. Terminal position and impact angle constraints are also imposed in the guidance problem. An open-loop skid-to-turn trajectory optimization problem is solved numerically and then used as an optimal trajectory to follow using closed-loop in-flight controls. This closed-loop guidance is based on linear quadratic regulation with a switchover to an impact angle guidance law. In this paper we also investigate the effectiveness of a preview term based on prediction of the future trajectory from the current state. Results with and without the preview term are presented for a test example.
Question Retrieval for Community-based Question Answering via Heterogeneous Network Integration Learning

Community based question answering platforms have attracted substantial users to share knowledge and learn from each other. As the rapid enlargement of CQA platforms, quantities of overlapped questions emerge, which makes users confounded to select a proper reference. It is urgent for us to take effective automated algorithms to reuse historical questions with corresponding answers. In this paper we focus on the problem with question retrieval, which aims to match historical questions that are relevant or semantically equivalent to resolve one s query directly. The challenges in this task are the lexical gaps between questions for the word ambiguity and word mismatch problem. Furthermore, limited words in queried sentences cause sparsity of word features. To alleviate these challenges, we propose a novel framework named HNIL which encodes not only the question contents but also the askers social interactions to enhance the question embedding performance. More specifically, we apply random walk based learning method with recurrent neural network to match the similarities between askers question and historical questions proposed by other users. Extensive experiments on a large scale dataset from a real world CQA site show that employing the heterogeneous social network information outperforms the other state of the art solutions in this task.
Light chain replacement: a new model for antibody gene rearrangement

A functional B cell antigen receptor is thought to regulate antibody gene rearrangement either by stopping further rearrangement (exclusion) or by promoting additional rearrangement (editing). We have developed a new model to study the regulation of antibody gene rearrangement. In this model, we used gene targeting to replace the J kappa region with a functional V kappa-J kappa light chain gene. Two different strains of mice were created; one, V kappa 4R, has a V kappa 4-J kappa 4 rearrangement followed by a downstream J kappa 5 segment, while the other, V kappa 8R, has a V kappa 8-J kappa 5 light chain. Here, we analyze the influence of these functional light chains on light chain rearrangement. We show that some V kappa 4R and V kappa 8R B cells only have the V kappa R light chain rearrangement, whereas others undergo additional rearrangements. Additional rearrangement can occur not only at the other kappa allele or isotype (lambda), but also at the targeted locus in both V kappa 4R and V kappa 8R. Rearrangement to the downstream J kappa 5 segment is observed in V kappa 4R, as is deletion of the targeted locus in both V kappa 4R and V kappa 8R. The V kappa R models illustrate that a productively rearranged light chain can either terminate further rearrangement or allow further rearrangement. We attribute the latter to editing of autoantibodies and to corrections of dysfunctional receptors.
Chapter XXVI Hofstede's Dimensions of National Culture in IS Research *

In this chapter, the authors do a citation analysis on Hofstede’s Culture’s Consequences in IS research to re-examine how IS research has used Hofstede’s national culture dimensions. They give a brief history of Hofstede’s research, and review Hofstede’s cultural dimensions and the measurement of them. The authors then present the results from their original citation analysis (which included years 1994-1999) from Ford, Connelly and Meister (2003) and their follow-up citation analysis (years 2000-2005). The authors examine the extent to which Hofstede’s national culture dimensions inform IS research, what areas of IS research have used them, and what changes have occurred since the original citation analysis. They then discuss the implications for IS research.
Real-time simulation of tissue deformation for the nasal endoscopy simulator (NES).

Endonasal sinus surgery requires a great amount of training before it can be adequately performed. The complicated anatomy involved, the proximity of relevant structures, and the variability of the anatomy due to inborn or iatrogenic variations make several complications possible. Today, cadaver dissections are the "gold standard" for surgical training. To overcome the drawbacks of traditional training methods, the Fraunhofer Institute for Computer Graphics is currently developing a highly interactive medical simulation system for nasal endoscopy and endonasal sinus surgery, in cooperation with the Mainz University Hospital. For the simulation of a rhinoscopic procedure, not only are the realization of the 3D interaction and the geometric representation of the anatomical structures necessary, but also a real-time simulation of the deformation behavior constrained by the instrument collisions. The challenge is to close the gap between a maximal degree of realism and the required real-time conditions.
Psychics Versus UFOs: The New Gender War? 1

Nine out of ten American adults admit to having at least some belief in paranormal phenomena. While there is no significant sex difference in amount of belief, females tend to believe in phenomena, such as psychic ability, more than males. Males are more willing to believe in UFOs than are females. One explanation for this sex difference is that men are agentic-instrumental, taking an active approach to thinking and learning, while women are communal-expressive, putting emphasis on emotions. Phase I of this study assessed undergraduates to determine whether the population of students exhibited the sex difference in belief. The goal of Phase II was to attempt to increase belief in psychics among males by providing concrete anchors for them to associate with a (“pseudo”) psychic reading.
‘What is this active surveillance thing?’ Men's and partners' reactions to treatment decision making for prostate cancer when active surveillance is the recommended treatment option

In the past decade, localised prostate cancer (LPC) management has been shifting from three radical treatment options (radical prostatectomy, external beam radiotherapy, or brachytherapy) to also include active surveillance (AS). This study examines men with LPC and partners' experiences of choosing between AS and radical treatments, and their experiences of AS when selected.
Reinterpreting the transport protocol stack to embrace ossification

Ubiquitous deployment of middleboxes has resulted in ossification of the transport layer, with TCP and UDP becoming part of the narrow waist of the Internet. This is a necessary stage in the evolution of the network, caused by its progression from research, to production, to increasingly critical infrastructure. New transport layer protocols will be needed in future, but since we are working with essential infrastructure, we cannot expect to have scope to make wholesale rapid changes. Future development must be done using the existing protocols as substrates, always maintaining on-the-wire compatibility. To advance, we must embrace the ossification of the network, and learn to reinterpret and extend the existing protocols.
Marine mammals and noise : Problems with root mean square sound pressure levels for transients

Current mitigation levels for noise transients impinging on marine mammals are specified by rms pressures. The rms measure critically relies upon choosing the size of averaging window for the squared pressures. Derivation of this window is not standardized, which can lead to 2–12 dB differences in rms sound pressure for the same wave forms. rms pressure does not represent the energy of the noise pulse and it does not prevent exposure to high peak pressures. Safety levels for transients should therefore be given by received peak–peak sound pressure and energy flux density instead of rms sound pressure levels. © 2005 Acoustical Society of America. @DOI: 10.1121/1.1921508 #
Risk Factors and Predictors of Severe Leptospirosis in New Caledonia

Background Leptospirosis is a major public health concern in New Caledonia (NC) and in other tropical countries. Severe manifestations of the disease are estimated to occur in 5–15% of all human infections worldwide and factors associated with these forms are poorly understood. Our objectives were to identify risk factors and predictors of severe forms of leptospirosis in adults. Methods and Findings We conducted a retrospective case-control study of inpatients with laboratory-confirmed leptospirosis who were admitted to two public hospitals in NC in 2008–2011. Cases were patients with fatal or severe leptospirosis, as determined by clinical criteria. This approach was meant to be pragmatic and to reflect the routine medical management of patients. Controls were defined as patients hospitalized for milder leptospirosis. Risk and prognostic factors were identified by multivariate logistic regression. Among the 176 patients enrolled in the study, 71 had criteria of severity including 10 deaths (Case Fatality Rate = 14.1%). Three risk factors were independently associated with severe leptospirosis: current cigarette smoking (OR = 2.94 [CI 1.45–5.96]); delays >2 days between the onset of symptoms and the initiation of antibiotherapy (OR = 2.78 [CI 1.31–5.91]); and Leptospira interrogans serogroup Icterohaemorrhagiae as the infecting strain (OR = 2.79 [CI 1.26–6.18]). The following post-admission laboratory results correlated with poor prognoses: platelet count ≤50,000/µL (OR = 6.36 [CI 1.79–22.62]), serum creatinine >200 mM (OR = 5.86 [CI 1.61–21.27]), serum lactate >2.5 mM (OR = 5.14 [CI 1.57–16.87]), serum amylase >250 UI/L (OR = 4.66 [CI 1.39–15.69]) and leptospiremia >1000 leptospires/mL (OR = 4.31 [CI 1.17–15.92]). Conclusions To assess the risk of developing severe leptospirosis, our study illustrates the benefit for clinicians to have: i) the identification of the infective strain, ii) a critical threshold of qPCR-determined leptospiremia and iii) early laboratory results. In New Caledonia, preventative measures should focus on early presumptive antibacterial therapy and on rodent (reservoir of Icterohaemorrhagiae serogroup) control.
PAPR Reduction in OFDM using Combination of Statistical Transformation Distribution and Selected Mapping Method

Orthogonal Frequency Division Multiplexing (OFDM) offers a high spectral efficiency, smooth operation and effectiveness against multipath fading as its modulation technique. This modulation technique advancement is to increase the number of subcarriers to enhance efficiency. Despite of the number of subcarriers increases, certain time domain OFDM coefficients are likely to acquire unwanted high magnitudes of PAPR. This high PAPR cause the limit of the transmitter power efficiency. Therefore, cause spectral to spread and reduce the bit-error-rate (BER) performance. In order to allay these potential performance problems, a computationally efficient and low cost PAPR reduction method were proposed. The new method presents a combination of Statistical Redistribution Method (SRM) with Selected Mapping Method (SLM). The proposed scheme takes advantage of Selected Mapping (SLM) followed by the companding SRM technique to amplify the reduction of the PAPR of the OFDM signal. Simulation results indicate that about 5 dB reduction in PAPR is achieved compared with the conventional SLM algorithm.
Sources of dissociation in the forgetting trajectories of implicit and explicit knowledge

In this dissertation I investigate dissociations in the forgetting patterns of implicit and explicit knowledge. I claim that this approach may provide significant constraints for the assumption that a single system or mechanism determines both implicit and explicit processes. In the theoretical part, I construe a definition of implicit knowledge as information learned and retrieved without intention. I also explain the general role of single dissociations in theories of implicit knowledge. And I present an overview of the main lines of research concerned with the functions, operation, development, neural substrates, and forgetting patterns of implicit knowledge. In general, I argue that comparing the forgetting patterns of implicit and explicit knowledge may be best regarded from a graded perspective and may usefully bridge the gap between research on implicit learning and implicit memory. In a series of 4 Experiments university students were exposed to environmental regularities embedded in artificial grammar (AG) and serial reaction time (SRT) tasks. To compare the forgetting patterns, participants’ implicit (motorperformance based) and explicit (recognition based) knowledge was assessed before and after a retention interval. Taken together, the results indicate that explicit knowledge decays faster than implicit knowledge in both AG and SRT tasks. Furthermore, an interference task introduced instead of a retention interval produced the same pattern of dissociations. Finally, I conducted a set of simulations to asses the ability of a single-system model (Shanks, Wilkinson, & Channon, 2003) to account for my experimental results. The simulations showed that the model best fits the empirical data by introducing changes in the parameters related to (a) the common knowledge strength (for implicit and implicit knowledge), and (b) the reliability for the explicit test. In sum, my dissertation (1) suggests a conceptual framework for implicit and explicit knowledge, (2) provides new empirical evidence of dissociations in their forgetting patterns, and (3) identifies specific boundary conditions for a singlesystem model.
The tabby syndrome in the mouse

The tabby syndrome in the mouse (which is common to the sex-linked gene for tabby and autosomal genes for crinkled and downless) affects the coat, the sinus hairs, the teeth, many glands and some surface features like tail rings, plicae digitales and the papilla vallata of the tongue. All these structures develop by the downgrowth of solid epithelial buds into the underlying mesenchyme. Organs which arise by invagination (like the neural tube or the otic vesicles and certain glands) are not affected by the tabby syndrome. The rudiments of glands and sinus hairs are reduced in size, and if reduction goes beyond a critical point, stunted organs are formed or, more commonly, the rudiments regress altogether. The same is true for the teeth and apparently for the whole syndrome. Measurements show the same situation in Ta ♂♂(and Ta/Ta ♀♀) and in heterozygous Ta/ + ♀♀. As in Ta ♂♂ and Ta/Ta ♀♀ there cannot be any doubt that a threshold mechanism is involved, there is no reason to assume that, in Ta/ + ♀♀, the identical defects are derived clonally from ancestral cells in which the Xchromosome carrying the normal allele has been inactivated. Whereas the Ta/ + phenotype does not give any evidence that the Ta locus is involved in X-chromosome inactivation, the possibility cannot be ruled out that, if inactivation should actually take place on the cellular level, the macroscopic phenotype could be the result of intercellular interactions along with the effects of threshold mechanisms.
Interaction analysis and visualization for asynchronous communication: analysis methods, tools and research questions

The present position paper describes interaction analysis issues about collaborative learning by design group blogging that are going to be discussed during the corresponding workshop at CSCL 2009. Blogging is quite popular and group blogging has interesting potential for learning. In the workshop we are going to work on interaction analysis graphs, experimental research findings and future directions.
Optimistic semi-supervised least squares classification

The goal of semi-supervised learning is to improve supervised classifiers by using additional unlabeled training examples. In this work we study a simple self-learning approach to semi-supervised learning applied to the least squares classifier. We show that a soft-label and a hard-label variant of self-learning can be derived by applying block coordinate descent to two related but slightly different objective functions. The resulting soft-label approach is related to an idea about dealing with missing data that dates back to the 1930s. We show that the soft-label variant typically outperforms the hard-label variant on benchmark datasets and partially explain this behaviour by studying the relative difficulty of finding good local minima for the corresponding objective functions.
