Relación entre los estilos educativos parentales o prácticas de crianza y la ansiedad infanto-juvenil: una revisión bibliográfica

Anxiety is one of the most common pathologies in the childhood and adolescent population and it has a high comorbidity that sometimes makes diagnosis and treatment very difficult. It also tends to persist over time, causing great difficulties in the daily life of children and adolescents. In this review the empirical evidence for the relationship between parenting styles and practices and anxiety in children and adolescents is analysed based on twenty-two articles. Reasonably consistent evidence was found, based mainly on European populations, that lower levels of anxiety, or fewer anxiety symptoms or internalising symptoms were related to affection, warmth, and acceptance from parents. In contrast, higher levels or more of these symptoms were linked to authoritarian style, rejection, psychological control, excessive parental control, over-involvement, rigid discipline, and hostile control. Furthermore, the review provided evidence of the need to develop preventive family education programmes and include parenting practices as an important part of the process for treating childhood and adolescent anxiety.
POSCAT: A Morpheme-based Speech Corpus Annotation Tool

As more and more speech systems require linguistic knowledge to accommodate various levels of applications, corpora that are tagged with linguistic annotations as well as signal-level annotations are highly recommended for the development of today’s speech systems. Among the linguistic annotations, POS (part-of-speech) tag annotations are indispensable in speech corpora for most modern spoken language applications of morphologically complex agglutinative languages such as Korean. Considering the above demands, we have developed a single unified speech corpus annotation tool that enables corpus builders to link linguistic annotations to signal-level annotations using a morphological analyzer and a POS tagger as basic morpheme-based linguistic engines. Our tool integrates a syntactic analyzer, phrase break detector, grapheme-to-phoneme converter and automatic phonetic aligner together. Each engine automatically annotates its own linguistic and signal knowledge, and interacts with the corpus developers to revise and correct the annotations on demand. All the linguistic/phonetic engines were developed and merged with an interactive visualization tool in a client-server network communication model. The corpora that can be constructed using our annotation tool are multi-purpose and applicable to both speech recognition and text-tospeech (TTS) systems. Finally, since the linguistic and signal processing engines and user interactive visualization tool are implemented within a client-server model, the system loads can be reasonably distributed over several machines.
Intimate Partner Violence and Help-Seeking: A Systematic Review and Social Psychological Tracks for Future Research

Intimate partner violence (IPV) is a global social concern: many women are affected by this phenomenon and by the difficulty of putting an end to it. This review of the literature aims to identify help-seeking facilitating and inhibiting factors in response to IPV. It was carried out on the PsycINFO and Medline databases using the following keywords: “intimate partner violence,” “domestic violence,” “help-seeking,” and “help-seeking barrier. ” Ninety out of 771 eligible publications were included on the basis of inclusion criteria. The results highlight that (1) research on this phenomenon is very recent and underdeveloped in Europe, (2) theoretical and conceptual frameworks are poorly developed and extended, (3) there is a significant impact of violence characteristics (e.g., severity, type) on help-seeking, and (4) help-seeking is a complex and multifactorial process influenced by a wide range of factors simultaneously individual and social. To conclude, these findings lead us to propose a psychosocial conceptualization of the help-seeking process by indicating how the levels of explanation approach in social psychology can be applied to this field of research in order to increase our understanding of this phenomenon.
PIP2 signaling, an integrator of cell polarity and vesicle trafficking in directionally migrating cells

Cell migration is a fundamental cellular process required for embryonic development to wound healing and also plays a key role in tumor metastasis and atherosclerosis. Migration is regulated at multiple strata, from cytoskeletal reorganization to vesicle trafficking. In migrating cells, signaling pathways are integrated with vesicle trafficking machineries in a highly coordinated fashion to accomplish the recruitment and trafficking of the trans-membrane proteins toward the leading edge. Different signaling molecules regulate cell migration in different physio-pathological contexts, among them, phosphatidylinositol-4,5-biphosphate (PIP2) is an integral component of the plasma membrane and pleiotropic lipid signaling molecule modulating diverse biological processes, including actin cytoskeletal dynamics and vesicle trafficking required for cell migration. In this commentary, we provide a brief overview of our current understandings on the phosphoinositide signaling and its implication in regulation of cell polarity and vesicle trafficking in migrating cells. In addition, we highlight the coordinated role of PIPKIγi2, a focal adhesion-targeted enzyme that synthesizes PIP2, and the exocyst complex, a PIP2-effector, in the trafficking of E-cadherin in epithelial cells and integrins in migrating cancer cells.
Software abstractions for mobile RFID‐enabled applications

Our everyday environments may soon be pervaded with radio frequency identification (RFID) tags integrated in physical objects. These RFID tags can store a digital representation of the physical object and transmit it wirelessly to pervasive, context‐aware applications running on mobile devices. However, communicating with RFID tags is prone to many failures inherent to the technology. This hinders the development of such applications, as traditional programming models require the programmer to deal with the RFID hardware characteristics manually. On the other hand, traditional RFID middleware focuses on limited scenarios in an enterprise context and not on general ubiquitous computing scenarios. In this paper, we extend the ambient‐oriented programming paradigm to program RFID applications, by considering RFID tags as intermittently connected mutable proxy objects hosted on mobile distributed computing devices, and detail our prototype implementation.

Performance evaluation of the IEEE 802.11e EDCA access method

Wireless local area networks (WLANs) are increasingly popular because of their flexibility. This spreading of WLANs comes with an increasing use of multimedia applications. Such applications are bandwidth sensitive and require a quality of service (QoS) that guarantees high performance transmission of continuous data. This requirement is the focus of the new enhanced IEEE 802.11e standard protocol for WLANs. This paper presents a simulation study of the enhanced distributed channel access method (EDCA) in the new IEEE 802.11e standard protocol. This protocol is evaluated to verify that it achieves superior QoS performance for real-time applications compared with the earlier legacy IEEE 802.11 DCF access method. A Simulation experiments - using the network simulator NS2- are carried out to compare the performance of both protocols regarding the throughput, delay, and jitter.

The effects of fasting and cold exposure on metabolic rate and mitochondrial proton leak in liver and skeletal muscle of an amphibian, the cane toad Bufo marinus

SUMMARY Futile cycling of protons across the mitochondrial inner membrane contributes significantly to standard metabolic rate in a variety of ectothermic and endothermic animals, but adaptations of the mitochondrial bioenergetics to different environmental conditions have rarely been studied in ectotherms. Changes in ambient temperature and nutritional status have a great effect on the physiological demands of ectothermic amphibians and may require the adjustment of mitochondrial efficiency. In order to investigate the effect of temperature and nutritional status on the mitochondrial level, we exposed male cane toads to either 10°C or 30°C and fasted half of the animals in each group. Cold exposure resulted in a fourfold reduction of the resting metabolic rate whereas nutritional status had only minor effects. The mitochondrial adjustments to each condition were observed by comparing the proton leak kinetics of isolated liver and skeletal muscle mitochondria at 25°C. In response to cold exposure, liver mitochondria showed a decrease in proton conductance while skeletal muscle mitochondria were unchanged. Additional food deprivation had minor effects in skeletal muscle, but in liver we uncovered surprising differences in energy saving mechanisms between the acclimation temperatures: in warm-acclimated toads, fasting resulted in a decrease of the proton conductance whereas in cold-acclimated toads, the activity of the respiratory chain was reduced. To investigate the molecular mechanism underlying mitochondrial proton leakage, we determined the adenine-nucleotide transporter (ANT) content, which explained tissue-specific differences in the basal proton leak, but neither the ANT nor uncoupling protein (UCP) gene expression correlated with alterations of the proton leak in response to physiological stimuli.
User attitudes to concatenated natural speech and text-to-speech synthesis in an automated information service

Today’s automated telephone services generally use recorded speech from one speaker for all output. In applications with large and varying output vocabularies, such as place names, it may be necessary to employ a second speaker to provide new vocabulary items if the original speaker is not available, or to use text-tospeech (TTS) synthesis for the whole or parts of the output. This paper reports a comparison of 10 schemes for the generation of spoken output in a travel information service, ranging from natural speech from a single speaker, through combinations of different voices and of natural and synthetic speech, to TTS synthesis throughout. The results show strong preferences for concatenated speech over TTS and for professionalquality recordings over amateur ones, and a weaker preference for a single speaker over two speakers.
Lingua italiana in bocca calabra: Italian in Calabria

1.1 Lingua toscana in bocca romana The main title of the present article, Lingua italiana in bocca calabra, is clearly a play on words of the well-known saying Lingua toscana in bocca romana. The latter highlights a long-standing belief, especially among foreign travellers on the Grand Tour, that the Italian spoken in Tuscany cannot, and should not, be considered to be the best form of Italian. One of its earliest attestations is to be found in Alexandre De Rogissart’s Les délices de l’Italie (1709) who, writing in 1701, informed the interested traveller that:
Identification and mapping of inhibitory sequences in the human immunodeficiency virus type 2 vif gene

Human immunodeficiency virus (HIV) regulates the expression of its genes temporally at the mRNA processing step. A subset of the mRNA species which encode the structural and some accessory genes contains inhibitory sequences (INS or CRS elements) which prevent nuclear export of the RNA or its utilization in the cytoplasm. Such inhibition is overridden by the interaction of a viral protein, Rev, with its RNA target sequence, RRE. The vif gene product, which is essential for virus replication in vivo, is encoded by a singly spliced mRNA, and its expression is dependent on rev in infected cells. However, INS elements have not been found in the HIV-1 vif gene itself, although such elements have been observed in Gag, Pol, and Env coding sequences. We have now identified an INS within the 5' half of HIV-2 vif which does not show any homology with cellular mRNAs or other previously identified INS and CRS elements of HIV. These results suggest that retroviral mRNAs have novel labile sequences different from those of cellular mRNAs.
Drowsy driving detection based on human pulse wave by photoplethysmography signal processing

Drowsiness of driver while driving is one major factor of traffic accident. Therefore, there are many researches to prevent and detect drowsy driving. Recent researches have focused on motion detection using cameras to determine drowsy driving. However, we have focused on non-invasive and inexpensive drowsiness detection system. In our previous research, we suggested a system based on the driver's head movement using infrared sensors. In this paper, we suggest another non-invasive and inexpensive system based on the driver's pulse wave by photoplethysmography (PPG) signal processing. Firstly, the system collects a pulse wave from a PPG sensor on a steering wheel and then it processes the signal to analyze driver's state. In order to evaluate the effectiveness of a human pulse wave for drowsiness detection, we integrated two systems. The experimental result using new integration system showed 83 percent drowsy driving detection rate in the state of real driving.
Image Authenticity and Perceptual Optimization via Genetic Algorithm and a Dependence Neighborhood

the content integrity of the multimedia has been exploited extensively in the last decade. We propose the idea of using genetic algorithm and non-deterministic dependence by involving the un-watermarkable coefficients for digital image authentication. Genetic algorithm is used to intelligently select coefficients for watermarking in a DCT based image authentication scheme, which implicitly watermark all the un-watermarkable coefficients also, in order to thwart different attacks. Experimental results show that such intelligent selection results in improvement of imperceptibility of the watermarked image, and implicit watermarking of all the coefficients improves security against attacks such as cover-up, vector quantization and transplantation.
Reflection-dominated X-ray spectra of narrow-line Seyfert 1 galaxies: Mrk 478 and EXO 1346.2+2645

Multi-epoch XMM-Newton spectra of the two Narrow Line Seyfert 1 (NLS1), Mrk 478 and EXO 1346.2+2645, are presented. The data were fitted with different models, including the relativistically-blurred reflection model reflionx, which was found to give a good description of both spectra in all epochs. The two sources are reflection dominated with the illuminating continuum hidden from view. This can be explained either in terms of a corrugated disc or strong gravitational light bending effects. The emission from these two sources comes from a very small region (few gravitational radii), very close to a rapidly spinning black hole. Spectral variability analysis show that both sources have constant RMS spectra, and constant hardness ratios in all epochs, in agreement with a single spectral component. The constancy the spectrum between high and low states rules out alternative models such as partial covering.
Comparative genomics and mutagenesis analyses of choline metabolism in the marine R oseobacter clade

Summary Choline is ubiquitous in marine eukaryotes and appears to be widely distributed in surface marine waters; however, its metabolism by marine bacteria is poorly understood. Here, using comparative genomics and molecular genetic approaches, we reveal that the capacity for choline catabolism is widespread in marine heterotrophs of the marine Roseobacter clade (MRC). Using the model bacterium R uegeria pomeroyi, we confirm that the bet A, bet B and bet C genes, encoding choline dehydrogenase, betaine aldehyde dehydrogenase and choline sulfatase, respectively, are involved in choline metabolism. The bet T gene, encoding an organic solute transporter, was essential for the rapid uptake of choline but not glycine betaine (GBT). Growth of choline and GBT as a sole carbon source resulted in the re‐mineralization of these nitrogen‐rich compounds into ammonium. Oxidation of the methyl groups from choline requires formyltetrahydrofolate synthetase encoded by fhs in R . pomeroyi, deletion of which resulted in incomplete degradation of GBT. We demonstrate that this was due to an imbalance in the supply of reducing equivalents required for choline catabolism, which can be alleviated by the addition of formate. Together, our results demonstrate that choline metabolism is ubiquitous in the MRC and reveal the role of Fhs in methyl group oxidation in R . pomeroyi.
Land Investment by Japanese Firms during and after the Bubble Period

This paper investigates (i) what has determined the land investment behavior of Japanese firms since the latter half of the 1980s; and (ii) how the current market prices of their land assets diverge from their shadow prices (marginal values of land investment). To do so, we estimate nonlinear land investment functions using micro panel corporate data, and calculate the partial q for land assets taking account of their collateral role. The land investment functions reveal that firms, in particular those in the real estate related industries, have been net sellers of land in the 1990s, mainly in response to the decline in sales and the deterioration in financial conditions after the bursting of the bubble. Moreover, manufacturing firms have also sold land because of the hike in the overseas production ratio. Partial q shows that the market price of land held by the real estate related industries has exceeded its shadow price since the latter half of the 1980s. For other industries, market land prices declined to the level of their shadow prices around the middle of the 1990s. However, since then market prices have once again found themselves above their shadow prices, in the face of the pessimistic expectations revealed by distressed share prices after 1997.
Stretching and wiggling liquids

This paper presents a novel framework for simulating the stretching and wiggling of liquids. We demonstrate that complex phase-interface dynamics can be effectively simulated by introducing the Eulerian vortex sheet method, which focuses on the vorticity at the interface (rather than the whole domain). We extend this model to provide user control for the production of visual effects. Then, the generated fluid flow creates complex surface details, such as thin and wiggling fluid sheets. To capture such high-frequency features efficiently, this work employs a denser grid for surface tracking in addition to the (coarser) simulation grid. In this context, the paper proposes a filter, called the liquid-biased filter, which is able to downsample the surface in the high-resolution grid into the coarse grid without unrealistic volume loss resulting from aliasing error. The proposed method, which runs on a single PC, realistically reproduces complex fluid scenes.
Improved Recognition of Spontaneous Hungarian Speech—Morphological and Acoustic Modeling Techniques for a Less Resourced Task

Various morphological and acoustic modeling techniques are evaluated on a less resourced, spontaneous Hungarian large-vocabulary continuous speech recognition (LVCSR) task. Among morphologically rich languages, Hungarian is known for its agglutinative, inflective nature that increases the data sparseness caused by a relatively small training database. Although Hungarian spelling is considered as simple phonological, a large part of the corpus is covered by words pronounced in multiple, phonemically different ways. Data-driven and language specific knowledge supported vocabulary decomposition methods are investigated in combination with phoneme- and grapheme-based acoustic modeling techniques on the given task. Word baseline and morph-based advanced baseline results are significantly outperformed by using both statistical and grammatical vocabulary decomposition methods. Although the discussed morph-based techniques recognize a significant amount of out of vocabulary words, the improvements are due not to this fact but to the reduction of insertion errors. Applying grapheme-based acoustic models instead of phoneme-based models causes no severe recognition performance deteriorations. Moreover, a fully data-driven acoustic modeling technique along with a statistical morphological modeling approach provides the best performance on the most difficult test set. The overall best speech recognition performance is obtained by using a novel word to morph decomposition technique that combines grammatical and unsupervised statistical segmentation algorithms. The improvement achieved by the proposed technique is stable across acoustic modeling approaches and larger with speaker adaptation.
Understanding the Social Meaning of Infertility and Childbearing: A Qualitative Study of the Perception of Childbearing and Childlessness in Northern Ghana

Background Infertility is a major medical condition that affects many married couples in sub-Saharan African and as such associated with several social meanings. This study therefore explored community's perception of childbearing and childlessness in Northern Ghana using the Upper West Region as a case study. Methods The study was exploratory and qualitative using in-depth and key informant interviews and focus group discussions. Fifteen marriage unions with infertility (childless), forty-five couples with children, and eight key informants were purposively sampled and interviewed using a semi-structured interview guides. Three focus group discussions were also carried out, one for childless women, one for women with children and one with men with children. The data collected were transcribed, coded, arranged, and analyzed for categories and themes and finally triangulated. Results The study revealed that infertility was caused by both social and biological factors. Socially couples could become infertile through supernatural causes such as bewitchment, and disobediences of social norms. Abortion, masturbation and use of contraceptives were also identified as causes of infertility. Most childless couples seek treatment from spiritualist, traditional healers and hospital. These sources of treatment are used simultaneously. Conclusion Childbearing is highly valued in the community and Childlessness is highly engendered, and stigmatised in this community with manifold social consequences. In such a community therefore, the concept of reproductive choice must encompass policies that make it possible for couples to aspire to have the number of children they wish.
