Análisis psicométrico de las escalas Ryff (versión española) en una muestra de adolescentes chilenos

espanolEl presente trabajo analiza las propiedades psicometricas de la escala de bienestar psicologico de Ryff (en su version en espanol), en adolescentes chilenos. La muestra estuvo compuesta por 335 adolescentes de la comuna de Talca, Chile, a quienes se aplico la escala de bienestar psicologico en su version de 39 items validada para poblacion espanola. Se realizaron analisis de confiabilidad y de validez de constructo encontrandose que la confiabilidad de la escala general fue buena, aunque por dimensiones tomo valores entre aceptables y malos. En cuanto a la validez, el modelo propuesto por Ryff fue el que mostro el mejor ajuste teorico a los datos entre los modelos comparados, propiedades que mejoraron al reducir la escala siguiendo criterios estadisticos. EnglishThe present work examines the psychometric properties of the psychological well-being scale proposed by Ryff (Spanish version) in Chilean adolescents. The sample consisted of 335 adolescents from the city of Talca, Chile, who completed the scale of psychological well-being in its version of 39 items validated for Spanish population. Reliability and construct validity analysis was conducted, resulting in a good reliability value for the entire scale, although by dimensions it took values between acceptable and bad. Regarding construct validity, the model proposed by Ryff showed the best theoretical fit compared with alternatives. Both psychometric properties were improved by reducing the amount of items in the scale according to statistical criteria.
The Study of Cooperative Obstacle Avoidance Method for MWSN Based on Flocking Control

Compared with the space fixed feature of traditional wireless sensor network (WSN), mobile WSN has better robustness and adaptability in unknown environment, so that it is always applied in the research of target tracking. In order to reach the target, the nodes group should find a self-adaptive method to avoid the obstacles together in their moving directions. Previous methods, which were based on flocking control model, realized the strategy of obstacle avoidance by means of potential field. However, these may sometimes lead the nodes group to fall into a restricted area like a trap and never get out of it. Based on traditional flocking control model, this paper introduced a new cooperative obstacle avoidance model combined with improved SA obstacle avoidance algorithm. It defined the tangent line of the intersection of node's velocity line and the edge of obstacle as the steering direction. Furthermore, the cooperative obstacle avoidance model was also improved in avoiding complex obstacles. When nodes group encounters mobile obstacles, nodes will predict movement path based on the spatial location and velocity of obstacle. And when nodes group enters concave obstacles, nodes will temporarily ignore the gravity of the target and search path along the edge of the concave obstacles. Simulation results showed that cooperative obstacle avoidance model has significant improvement on average speed and time efficiency in avoiding obstacle compared with the traditional flocking control model. It is more suitable for obstacle avoidance in complex environment.
Linear superposition coding for the asymmetric Gaussian MAC with quantized feedback

We propose a linear transceiver scheme for the asymmetric two-user multiple access channel with additive Gaussian noise and quantized feedback. The quantized feedback link is modeled as an information bottleneck subject to a rate constraint. We introduce a superposition scheme that splits the transmit power between an Ozarow-like linear-feedback code and a conventional code that ignores the feedback. We study the achievable sum rate as a function of the feedback quantization rate and we show that sum rate maximization leads to a difference of convex functions problem that we solve via the convex-concave procedure.
Miniaturized Triple Band Microstrip Patch Antenna with Defected Ground Structure for Wireless Communication Applications

paper presents a miniaturized triple band multi frequency antenna. The proposed antenna can generate two separate impedance bandwidths to cover all the 2.4/5.2/5.8- GHz WLAN operating bands and the 2.5//5.5-GHz WiMAX bands. The proposed microstrip-fed antenna mainly consists of a circular ring, U-shape-like slots on substrate, and a defected ground structure having L-shape and staircase like slots. The design considerations for achieving broadband operation of the proposed Defected ground structure antenna are discussed, and theoretical results are presented. The antenna operates in two frequency bands, and impedance bandwidth of lower frequency band is 0.92 GHz from 2.37- 3.29 GHZ and upper frequency band is 2.57 GHz from 4.22- 6.29 GHz covering WLAN/WiMAX bands with a total bandwidth of 3.49 GHz. The overall size of the antenna is 22 mm × 36 mm × 1.6 mm including the finite ground CPW feeding mechanics. The parametric study is performed to understand the characteristics of the proposed antenna. Also, good antenna performances such as radiation patterns, current distribution, and efficiency and antenna gains over the operating bands have been observed. The antenna is simulated using IE3D software.
Neurophysiological Correlates of Information Systems Commonly Used Self-Reported Measures: A Multitrait Multimethod Study

Given the importance and criticality of instrument validation in IS research, the objective of this study is to provide a systematic assessment of IS construct validity via a multitrait multimethod (MTMM). In doing so, this paper uses structurally different methods -- neurophysiological and self-reported scales - to measure three commonly used IS constructs: engagement, arousal and cognitive load. The study's results generally support MTMM expectations and shed light on the complexity of detecting the nature of mono-method bias. More specifically, the study's results show that primitive perceptual IS constructs such as arousal are unlikely to suffer from mono-method bias, whereas more complex perceptual constructs such as engagement or cognitive load have higher within method correlations. There are two alternative explanations for the within method correlations: a) a method bias, or b) a combination between trait and method.
Area efficient device-parameter estimation using sensitivity-configurable ring oscillator

This paper proposes an area efficient device parameter estimation method with sensitivity-configurable ring oscillator (RO). This sensitivity-configurable RO has a number of configurations and the proposed method exploits this property for reducing sensor area and/or improving estimation accuracy. The proposed method selects multiple sets of sensitivity configurations, obtains multiple estimates and computes the average of them for accuracy improvement exploiting an averaging effect. Experimental results with a 32-nm predictive technology model show that the proposed method can reduce the estimation error by 49% or reduce the sensor area by 75% while keeping the accuracy.
Interactive visual analysis of multi-faceted scientific data

V isualization plays an important role in exploring, analyzing and presenting large and heterogeneous scientific data that arise in many disciplines of medicine, research, engineering, and others. We can see that model and data scenarios are becoming increasingly multi-faceted: data are often multi-variate and time-dependent, they stem from different data sources (multi-modal data), from multiple simulation runs (multi-run data), or from multi-physics simulations of interacting phenomena that consist of coupled simulation models (multi-model data). The different data characteristics result in special challenges for visualization research and interactive visual analysis. The data are usually large and come on various types of grids with different resolution that need to be fused in the visual analysis. This thesis deals with different aspects of the interactive visual analysis of multi-faceted scientific data. The main contributions of this thesis are: 1) a number of novel approaches and strategies for the interactive visual analysis of multi-run data; 2) a concept that enables the feature-based visual analysis across an interface between interrelated parts of heterogeneous scientific data (including data from multi-run and multi-physics simulations); 3) a model for visual analysis that is based on the computation of traditional and robust estimates of statistical moments from higher-dimensional multi-run data; 4) procedures for visual exploration of time-dependent climate data that support the rapid generation of promising hypotheses, which are subsequently evaluated with statistics; and 5) structured design guidelines for glyph-based 3D visualization of multi-variate data together with a novel glyph. All these approaches are incorporated in a single framework for interactive visual analysis that uses powerful concepts such as coordinated multiple views, feature specification via brushing, and focus+context visualization. Especially the data derivation mechanism of the framework has proven to be very useful for analyzing different aspects of the data at different stages of the visual analysis. The proposed concepts and methods are demonstrated in a number of case studies that are based on multi-run climate data and data from a multi-physics simulation.

Comparison of Topical Cyclosporine and Diquafosol Treatment in Dry Eye

Purpose To compare the treatment effects of topical cyclosporine A (CsA) and diquafosol sodium (DQS) for the treatment of moderate to severe dry eye disease (DED). Methods This prospective, nonrandomized, comparative study involved 60 eyes of 60 patients with moderate to severe DED who were treated with topical CsA 0.05% (group 1, 31 patients) or DQS 3% (group 2, 29 patients) in addition to artificial tears for 3 months. Before treatment, and at 1 and 3 months after treatment, the Ocular Surface Disease Index, tear breakup time, Schirmer score, tear clearance rate, and corneal and conjunctival staining scores were compared. Results Significant improvements in Ocular Surface Disease Index score, tear clearance rate, and corneal staining score were observed 1 month after treatment in group 2 (p = 0.014, p = 0.002, and p < 0.001, respectively), when compared with group 1. However, no significant differences were observed between the two groups 3 months after treatment (p > 0.05). Tear breakup times were significantly higher in group 2 compared with group 1 for the duration of the study (p < 0.001). Three months after treatment, Schirmer score was significantly higher and conjunctival staining score was significantly lower in group 1 compared with group 2 (p < 0.001). Conclusions Both topical CsA 0.05% and DQS 3% are effective in patients with moderate to severe DED. However, the timing and degree of therapeutic effects on tear film and ocular surface parameters, as well as symptoms, can be different between the two treatments.

Model-based Utility Functions

Abstract Orseau and Ring, as well as Dewey, have recently described problems, including self-delusion, with the behavior of agents using various definitions of utility functions. An agent's utility function is defined in terms of the agent's history of interactions with its environment. This paper argues, via two examples, that the behavior problems can be avoided by formulating the utility function in two steps: 1) inferring a model of the environment from interactions, and 2) computing utility as a function of the environment model. Basing a utility function on a model that the agent must learn implies that the utility function must initially be expressed in terms of specifications to be matched to structures in the learned model. These specifications constitute prior assumptions about the environment so this approach will not work with arbitrary environments. But the approach should work for agents designed by humans to act in the physical world. The paper also addresses the issue of self-modifying agents and shows that if provided with the possibility to modify their utility functions agents will not choose to do so, under some usual assumptions.

Testing theory in practice: a simple experiment

In this paper we discuss the experiences gained in conducting a simple testing experiment. The goal of this experiment is to apply the abstract, formal testing framework [8] in a practical setting, and to indicate the critical aspects in its application to realistic testing situations. For that purpose a formal description of the system under test (SUT) is made from which tests are systematically derived. These tests are interpreted and executed by a tester against concrete implementations, thereby giving an indication about the correctness of these implementations.
An observational longitudinal study to evaluate miction, defecation, and sexual function after radical hysterectomy with pelvic lymphadenectomy for early-stage cervical cancer

The objective of this study was to evaluate the problems with miction, defecation, and sexuality after a radical hysterectomy with or without adjuvant radiotherapy for the treatment of cervical cancer stage I–IIA. This study included an observational longitudinal study of self-reported bladder, defecation, and sexual problems with a baseline score. Ninety-four women were included in the study. An age-matched control group consisted of 224 women. The patients showed significantly more negative effects on sexual function compared with both the controls and their situation before the treatment throughout 24 months of follow-up. The problems included less lubrication, a narrow and short vagina, senseless areas around the labia, dyspareunia, and sexual dissatisfaction. Up to 12 months after the treatment, the patients complained significantly more of little or no urge to urinate and diarrhea as compared with the controls. Adjuvant radiotherapy did not increase the risk of bladder dysfunction, colorectal motility disorders, and sexual functions. We conclude that a radical hysterectomy for the treatment of early-stage cervical carcinoma is associated with adverse effects mainly on sexual functioning.
Extension of Memory Controller Equipped with MuCCRA-3-DP: Dynamically Reconfigurable Processor Array

In order to achieve a high performance on the Dynamically Reconfigurable Processor Array(DRPA), it is necessary to use PEs effectively. However, a prototype DRPA, MuCCRA-3-DP needs to generate read/write addresses for accessing data memories, and counts a number of loops on PEs. Hence, PEs of MuCCRA-3-DP can not be used effectively for actual processing of applications. To solve this problem and improve performance. We extend the memory controller of MuCCRA-3-DP and named it MuCCRA-3-EXMC. PEs of MuCCRA-3-EXMC can be concentrated on executing the actual processing by the extended memory controller performing address generation and loop count. Evaluation results showed that MuCCRA-3-EXMC can improve its performance by 12-23% and reduce its energy consumption by 9-20% without a large increase of its area.
An ultra-fast and scalable quantification pipeline for transposable elements from next generation sequencing data

Transposable elements (TEs) are DNA sequences which are capable of moving from one location to another and represent a large proportion (45%) of the human genome. TEs have functional roles in a variety of biological phenomena such as cancer, neurodegenerative disease, and aging. Rapid development in RNA-sequencing technology has enabled us, for the first time, to study the activity of TE at the systems level.However, efficient TE analysis tools are not yet developed. In this work, we developed SalmonTE, a fast and reliable pipeline for the quantification of TEs from RNA-seq data. We benchmarked our tool against TEtranscripts, a widely used TE quantification method, and three other quantification methods using several RNA-seq datasets from Drosophila melanogaster and human cell-line. We achieved 20 times faster execution speed without compromising the accuracy. This pipeline will enable the biomedical research community to quantify and analyze TEs from large amounts of data and lead to novel TE centric discoveries.
Blind source separation in machine monitoring

The paper presents a new approach for machine vibration analysis and health monitoring based on blind source separation (BSS). So, the problem is transferred from the original space of the measurements to the space of independent sources, where the reduced number of components is going to simplify the monitoring problem while the vibration analysis methods are going to be applied for scalar signals. The assessment of the approach on a real machine is presented in this paper.
Binge drinking: all too prevalent and hazardous

Alcohol use is the third greatest contributor to the global burden of disease,[1][1] estimated to cause 3.8% of all deaths. Among people aged 15 to 44 years, alcohol is estimated to result in 4.6% of all disability-adjusted life years lost and a disproportionate number of fatal injuries. [2][2]
Into the Himalayan Exile: The Phylogeography of the Ground Beetle Ethira clade Supports the Tibetan Origin of Forest-Dwelling Himalayan Species Groups

The Himalayan mountain arc is one of the hotspots of biodiversity on earth, and species diversity is expected to be especially high among insects in this region. Little is known about the origin of the Himalayan insect fauna. With respect to the fauna of high altitude cloud forests, it has generally been accepted that Himalayan lineages are derived from ancestors that immigrated from Western Asia and from adjacent mountainous regions of East and Southeast Asia (immigration hypothesis). In this study, we sought to test a Tibetan Origin as an alternative hypothesis for groups with a poor dispersal ability through a phylogeographic analysis of the Ethira clade of the genus Pterostichus. We sequenced COI mtDNA and the 18S and 28S rDNA genes in 168 Pterostichini specimens, including 46 species and subspecies of the Ethira clade. In our analysis, we were able to show that the Ethira clade is monophyletic and, thus, represents a Himalayan endemic clade, supporting endemism of two of the basal lineages to the Central Himalaya and documenting large distributional gaps within the phylogeographic structure of the Ethira clade. Furthermore, the molecular data strongly indicate very limited dispersal abilities of species and subspecies of these primary wingless ground beetles. These results are consistent with the hypothesis of a Tibetan Origin, which explains the evolution, diversity and distribution of the Himalayan ground beetle Ethira clade much more parsimoniously than the original immigration hypothesis.
Transient rapamycin treatment can increase lifespan and healthspan in middle-aged mice

The FDA approved drug rapamycin increases lifespan in rodents and delays age-related dysfunction in rodents and humans. Nevertheless, important questions remain regarding the optimal dose, duration, and mechanisms of action in the context of healthy aging. Here we show that 3 months of rapamycin treatment is sufficient to increase life expectancy by up to 60% and improve measures of healthspan in middle-aged mice. This transient treatment is also associated with a remodeling of the microbiome, including dramatically increased prevalence of segmented filamentous bacteria in the small intestine. We also define a dose in female mice that does not extend lifespan, but is associated with a striking shift in cancer prevalence toward aggressive hematopoietic cancers and away from non-hematopoietic malignancies. These data suggest that a short-term rapamycin treatment late in life has persistent effects that can robustly delay aging, influence cancer prevalence, and modulate the microbiome.

An Examination of the Interactive Effects of Mindfulness and Stress on Negative Health Habits in a Primary Care Population

The overarching goal of this study was to better understand relationships between health habits, stress, and mindfulness. In doing so, this research examined the interaction of mindfulness with responses to stress as it affects negative health habits. There was also a psychometric development study conducted, using confirmatory factor analyses (CFA) to test the applicability of the two-factor model of the PHLMS to a primary care population. Data were collected from 198 adult patients in a primary care medical practice. Participants ranged in age from 18 to 89 years old, were 51% female, and 92% Caucasian. For CFA analyses, three fit indexes were examined, and fit indexes marginally supported a two-factor model ( 2 /df = 2.26, CFI = .871, TLI = .851, RMSEA = .08). Despite differences in goodness of fit between this researcher’s data and the original model, it was found that the two-factor structure of the PHLMS demonstrated acceptable reliability and consistency when administered to a primary care population. Multiple linear regression analyses were then conducted to test the moderator hypothesis of Mindfulness; these regressions approached significance but did not achieve statistical significance. Although mindfulness was not found to moderate the relationship between stress and health behaviors, a further suggestion is to investigate the relationships between mindfulness, particularly mindful or nonjudgmental acceptance, and stress, as well as relationships between stress and health habits. This research demonstrated a clear relationship between acceptance as a factor of mindfulness, and stress. Based on these results, it is suggested that further investigation be carried out into the usefulness of acceptance-based interventions with chronically stressed primary care populations.
