ESTILOS DE CRIANZA Y EMPATÍA EN ADOLESCENTES IMPLICADOS EN CIBERBULLYING PARENTING STYLES AND EMPATHY IN ADOLESCENTS INVOLVED IN CYBERBULLYING

RESUMEN El presente estudio tuvo como finalidad analizar la relacion entre los estilos de socializacion parental, el proceso de empatia y el fenomeno del ciberbullying, cuyo ambito se expande mas alla de las fronteras fisicas de la escuela, pudiendose direccionar desde el hogar de los adolescentes a los escenarios digitales. Al respecto se investigo a los alumnos provenientes de instituciones educativas publicas y privadas de Lima Metropolitana obteniendo una muestra de 560 adolescentes de ambos sexos entre 13 y 17 anos. A esta muestra se le administro la escala de estilos de socializacion parental en la adolescencia (ESPA 29), que proporciona los estilos de socializacion parental de la madre y el padre, el Interpersonal Reactivity Index (IRI), que mide el grado de Empatia y el Cuestionario de Ciberbullying de Calvete, (E., Orue, I., Estevez, A., Villardon, y Padilla, P., 2009), que mide tanto la realizacion de ciberbullying como hecho de ser victima de ciberbullying. Se recogio la informacion mediante un diseno de tipo descriptivo-correlacional, con un muestreo por conglomerados de la poblacion a estudiar. Se encontraron correlaciones entre los estilos de socializacion parental y el grado de empatia; y entre el grado de empatia y la participacion en episodios de ciberbullying, sea en el rol de victima o en el de victimario, comprobandose tres de las cuatro hipotesis formuladas, a la vez que no se encontro correlaciones significativas entre los estilos de socializacion parental y la participacion en episodios de ciberbullying, rechazandose la cuarta hipotesis. Habiendose logrado la mayor parte de los objetivos propuestos en esta investigacion estos resultados coadyuvaran al desarrollo de un Protocolo de intervencion en ciberbullying, que facilitara el desarrollo de estrategias de promocion de comportamientos prosociales en la poblacion afectada.
Lectures on Etale Cohomology

The development of etale cohomology was motivated by work on the Weil conjectures, which state that local-zeta functions ζ(X, s), i.e. the generating function for the number of rational points of a projective variety defined over a finite field Fq in all finite extensions, satisfy certain properties analogous to those of the Riemann zeta function. Weil observed that the number of points defined over Fqk is given by the number of fixed points of X(Fq) of the k-th power of the Frobenius automorphism. Thus given an appropriate cohomology theory for varieties over a finite field (with co-efficients in a field of characteristic zero), this could be computed using the Lefschetz trace formula. In particular we require a so-called Weil cohomology theory, which shares the properties of singular cohomology for varieties defined over the complex numbers namely a contravariant functor H(−,K) from non-singular irreducible complete varieties over an algebraically closed field k to finite dimensional vector spaces over a characteristic zero field K, satisfying (amongst other things) the following:
Comparing Instructional Factors Related to Students’ Academic Self-Discipline in Norway and Finland

School learners can struggle with setting and striving for objectives that require sustained academic self‐discipline. We believe that teachers’ instructional qualities and school culture are factors that can successfully elicit students’ self-discipline in their academic work. This study explores and compares factors related to students’ academic self-discipline among Norwegian and Finnish youths at the upper secondary level. The Finnish students’ excellent results on international comparative tests have led many commentators to consider the Finnish model of education very worthy of emulation. Another reason to com-pare these two groups is that Finnish and Norwegian classrooms differ in their levels of in-class Internet access and computer use for learning purposes. From this perspective, it is interesting to compare empirical associations between instructional factors (as well as students’ school appreciation) and students’ academic self-discipline. The instructional factors in our theoretical model were teachers’ classroom management, teaching quality, teachers’ expressed expectations and the value students placed on the school as an institution. A total of 1433 urban Finnish and Norwegian upper secondary students in general study programmes participated in our cross-sectional questionnaire. We used structural equation modelling for our analysis, and the results show that the associations between instructional qualities (quality instruction, classroom management and high expectations) and academic self-discipline are overall stronger in the Finnish sample than the Norwegian sample. However, students’ appreciation for school was more highly associated with academic self-discipline in Norway than in Finland. Furthermore, the associations between in-class Internet access and motivational conflict were clearly higher in the Norwegian sample than in the Finnish sample. In both samples, we found strong associations between motivational conflict and academic self-discipline. We also discuss the meaning of these results and their implications for research and practice.
Hash-flow taint analysis of higher-order programs

As web applications have grown in popularity, so have attacks on such applications. Cross-site scripting and injection attacks have become particularly problematic. Both vulnerabilities stem, at their core, from improper sanitization of user input. We propose static taint analysis, which can verify the absence of unsanitized input errors at compile-time. Unfortunately, precise static analysis of modern scripting languages like Python is challenging: higher-orderness and complex control-flow collide with opaque, dynamic data structures like hash maps and objects. The interdependence of data-flow and control-flow make it hard to attain both soundness and precision. In this work, we apply abstract interpretation to sound and precise taint-style static analysis of scripting languages. We first define λH, a core calculus of modern scripting languages, with hash maps, dynamic objects, higher-order functions and first class control. Then we derive a framework of k-CFA-like CESK-style abstract machines for statically reasoning about λH, but with hash maps factored into a "Curried Object store. " The Curried object store---and shape analysis on this store---allows us to recover field sensitivity, even in the presence of dynamically modified fields. Lastly, atop this framework, we devise a taint-flow analysis, leveraging its field-sensitive, interprocedural and context-sensitive properties to soundly and precisely detect security vulnerabilities, like XSS attacks in web applications. We have prototyped the analytical framework for Python, and conducted preliminary experiments with web applications. A low rate of false alarms demonstrates the promise of this approach.
LACK OF BENEFIT OF A SINGLE DOSE OF SYNTHETIC HUMAN SECRETIN IN THE TREATMENT OF AUTISM AND PERVASIVE DEVELOPMENTAL DISORDER

A BSTRACT Background Secretin is a peptide hormone that stimulates pancreatic secretion. After recent publicity about a child with autism whose condition markedly improved after a single dose of secretin, thousands of children with autistic disorders may have received secretin injections. Methods We conducted a double-blind, placebocontrolled trial of a single intravenous dose of synthetic human secretin in 60 children (age, 3 to 14 years) with autism or pervasive developmental disorder. The children were randomly assigned to treatment with an intravenous infusion of synthetic human secretin (0.4 m g per kilogram of body weight) or saline placebo. We used standardized behavioral measures of the primary and secondary features of autism, including the Autism Behavior Checklist, to assess the degree of impairment at base line and over the course of a four-week period after treatment. Results Of the 60 children, 4 could not be evaluated — 2 received secretin outside the study, and 2 did not return for follow-up. Thus, 56 children (28 in each group) completed the study. As compared with placebo, secretin treatment was not associated with significant improvements in any of the outcome measures. Among the children in the secretin group, the mean total score on the Autism Behavior Checklist at base line was 59.0 (range of possible values, 0 to 158, with a larger value corresponding to greater impairment), and among those in the placebo group it was 63.2. The mean decreases in scores over the four-week period were 8.9 in the secretin group and 17.8 in the placebo group (mean difference, ¡8.9; 95 percent confidence interval, ¡19.4 to 1.6; P=0.11). None of the children had treatment-limiting adverse effects. After they were told the results, 69 percent of the parents of the children in this study said they remained interested in secretin as a treatment for their children. Conclusions A single dose of synthetic human secretin is not an effective treatment for autism or pervasive developmental disorder. (N Engl J Med 1999; 341:1801-6.)
How widespread is preaspiration in Italy ? A preliminary acoustic phonetic overview

Preaspiration is a comparatively rare phonetic feature, almost entirely confined to languages spoken in far northwestern Europe (Andersen 2002; Helgason 2002). A recent acoustic phonetic investigation into consonant gemination in Sienese Italian (e.g. Stevens & Hajek 2007), however, found that preaspiration occurred in one third of geminate /pp tt kk/ tokens. Up until that point preaspirated stops had not been reported to occur in Sienese or any other variety of Italian including the standard language. With this in mind, the present paper presents the results of an acoustic phonetic investigation into voiceless geminate stops /pp tt kk/ in a controlled corpus of words read by speakers from 15 other Italian cities. Results are analysed according to city as well as factors (e.g. speaker sex, vowel type) known to favour occurrences of preaspiration in other better known preaspirating languages. Preliminary duration values are presented and results are discussed in terms of two specific hypotheses regarding the rise of preaspiration in Sienese Italian. Introduction & background Geminate consonants in Italian Consonant length is contrastive in (standard) Italian e.g. pala ‘shovel’ v. palla ‘ball’. The duration of the consonant, that of the preceding vowel, and the ratio between them (C/V) all play a role in signalling phonological consonant length (e.g. Pickett et al. 1999). Geminate voiceless stops /pp tt kk/, in particular, are described as unaspirated in all prosodic positions in standard Italian (e.g. Bertinetto & Loporcaro 2005). Manner of articulation has not been a focus of existing experimental phonetic studies on geminates in standard Italian (e.g. Pickett et al. 1999), however post-aspiration of geminate voiceless stops is reported to occur in Calabria (Sorianello 1996). Degemination is a feature of northern varieties and the geminates of standard Italian as pronounced by these speakers are often less salient (Bertinetto & Loporcaro 2005). Standard Italian and regional varieties The linguistic situation in Italy is complex and the standard language, while historically derived from Florentine Italian, is today perhaps best described as an abstraction only used, and increasingly less so, by trained speakers (Bertinetto & Loporcaro 2005). The pronunciation of standard Italian is influenced by distinct regional accents, which can be very broadly categorized into those of the north, centre (Tuscany) and south. The present study involves a list of standard Italian words read by speakers from 15 cities spread over these three regions. The controlled circumstances mean less regional influence on speakers’ pronunciation than would occur in a less formal setting. However, such data allow us to test whether preaspiration is a regional feature of Sienese or whether it occurs more widely and in standard Italian, as spoken across Italy.

A Nonlinear Ship Manoeuvering Model: Identification and adaptive control with experiments for a model ship

Complete nonlinear dynamic manoeuvering models of ships, with numerical values, are hard to find in the literature. This paper presents a modeling, identification, and control design where the objective is to manoeuver a ship along desired paths at different velocities. Material from a variety of references have been used to describe the ship model, its difficulties, limitations, and possible simplifications for the purpose of automatic control design. The numerical values of the parameters in the model is identified in towing tests and adaptive manoeuvering experiments for a small ship in a marine control laboratory.
The limits of public administration reform through World Bank capacity development: the case of Moldova

ABSTRACT The paper explores the concept of World Bank capacity development. It argues that capacity development is under-defined, enabling the World Bank to live up to often contradictory demands toward domestic development and retaining legitimacy as a ‘knowledge bank’. On the ground, vagueness translates into technocratic approaches to institutional reform, based on a simple definition of learning. The case of central public administration reform in Moldova demonstrates how institutional changes under the label of capacity development translated into little change in administrative behavior. It shows how a country can maintain a sense of modernization through capacity development despite little actual change.
Roles of Titin in the Structure and Elasticity of the Sarcomere

The giant protein titin is thought to play major roles in the assembly and function of muscle sarcomeres. Structural details, such as widths of Z- and M-lines and periodicities in the thick filaments, correlate with the substructure in the respective regions of the titin molecule. Sarcomere rest length, its operating range of lengths, and passive elastic properties are also directly controlled by the properties of titin. Here we review some recent titin data and discuss its implications for sarcomere architecture and elasticity.
Extracting new product ideas from consumer blogs

This paper introduces a Web mining approach for automatically identifying and extracting new product ideas from internet blogs. There are a large amount of web logs for nearly each topic, where consumers present their needs for new products. These new product ideas are valuable to producers, researchers and developers because they can lead to a new product development process, a well-known task in marketing. However, the current approach towards extraction of these new product ideas involves employed analysts to process these blogs manually and extract the new product ideas. Here, presented is an automated approach towards the extraction of new product ideas through knowledge extraction and using scripting languages, which not only eliminates human error, but also speeds up the entire process of new product idea extraction. Thus, several product development solutions allow engineers, suppliers, business partners and even customers to collaborate throughout the entire product lifecycle via the Internet.
REGISTRATION OF TERRESTRIAL LASER SCANS VIA IMAGE BASED FEATURES

The complexity of natural scenes and the amount of information acquired by terrestrial laser scanners turns the registration among scans into a complex problem. This problem becomes even more complex when considering the relatively low angular resolution of terrestrial scanner compared to images, the monotonicity of manmade surfaces that makes the detection of corresponding objects difficult, and the lack of structure of vegetated objects that makes the detection of meaningful features difficult. Since most modern scanners are accompanied with consumer cameras of relatively high quality, it stands to reason making use of the image content for the registration process. Such alternative will benefit from the large body of image based registration work that has been carried out for several decades and therefore has the potential of providing an alternative and simple approach for the registration of pairs and multiple scans simultaneously. In this paper, we study the registration of terrestrial scans via image-based information. For this purpose, we propose an efficient autonomous model that supports the registration of multiple scans. Following the presentation of the model, we analyze its application to outdoor, complex scenes, ones that are common to find in actual laser scanning projects.
Strategy-proofness and Single-crossing I Am Grateful to Two Anonymous Referees and the Coeditor, Martin Osborne, for Helpful Comments and Corrections on an Earlier Draft. I Also Thank

This paper analyzes strategy-proof collective choice rules when individuals have single-crossing preferences on a finite and ordered set of social alternatives. It shows that a social choice rule is anonymous, unanimous, and strategy-proof on a maximal single-crossing domain if and only if it is an extended median rule with n − 1 fixed ballots distributed over the individuals' most preferred alternatives. As a by-product, the paper also proves that strategy-proofness implies the tops-only property. It also offers a strategic foundation for the so-called " single-crossing version " of the Median Voter Theorem, by showing that the median ideal point can be implemented in dominant strategies by a direct mechanism in which every individual reveals his true preferences. 1. I In social choice theory, a collective decision making process is usually represented by a social choice rule. A social choice rule associates a unique alternative from the set of feasible alternatives to every possible list of preferences of the individuals in the society. A social choice rule is said to be strategy-proof if no individual can ever benefit from misrepresenting his true preferences. A fundamental result in social choice theory , known as the Gibbard (1973)–Satterthwaite (1975) Theorem, shows that, if the set of alternatives contains at least three possible outcomes and individual preferences are not restricted in any particular way, then every strategy-proof social choice rule is dictatorial. That is, there is an individual whose preferences always dictate the final choice regardless of the other individuals' preferences. The Gibbard–Satterthwaite Theorem holds under the so called universal domain assumption , which means that every profile of complete and transitive preference relations is an admissible element of the domain of the social choice rule. In many economic and political applications, however, preferences satisfy additional properties. A case in point is the single-peaked property.
The Two-Level-Turn-Model Fault-tolerant Routing Scheme in Tori with Convex Faults

In this paper, we would present a fault-tolerant wormhole routing scheme, called two-level-turn-model scheme, in the tori with convex faults. The reason why we choose the convex faults is that the shape of the convex faults is instrumental to design an effective fault-tolerant routing algorithm. Compared with many other solutions, which mainly focus on providing extra virtual channels to tolerate the faults, one of the advantages of our solution is that it is based on the turn model, which itself could tolerate some faults for some messages. At the same time, our solution could work effectively no matter where the fault region locates and no matter whether the fault regions are connected. In our solution, two patterns of the turn model are complementary to tolerate the faults. With a few limits to the shape of the convex faults, at most five virtual channels per physical channel are required to avoid the deadlock.
Combined Human, Antenna Orientation in Elevation Direction and Ground Effect on RSSI in Wireless Sensor Networks

In this paper, we experimentally investigate the combined effect of human, antenna orientation in elevation direction and the ground effect on the Received Signal Strength Indicator (RSSI) parameter in the Wireless Sensor Network (WSN). In experiment, we use MICAz motes and consider different scenarios where antenna of the transmitter node is tilted in elevation direction. The motes were placed on the ground to take into account the ground effect on the RSSI. The effect of one, two and four persons on the RSSI is recorded. For one and two persons, different walking paces e.g. slow, medium and fast pace, are analysed. However, in case of four persons, random movement is carried out between the pair of motes. The experimental results show that some antenna orientation angles have drastic effect on the RSSI, even without any human activity. The fluctuation count and range of RSSI in different scenarios with same walking pace are completely different. Therefore, an efficient human activity algorithm is need that effectively takes into count the antenna elevation and other parameters to accurately detect the human activity in the WSN deployment region.
Art islands on the plateau: rock art site complexes in the Jawoyn Lands of the Arnhem Land Plateau

Abstract The surface of the Arnhem Land Plateau, northern Australia, contains numerous rock outcrops of varying size and geomorphic complexity. Erosion of these isolated outcrops has led to the development of discrete clusters of rockshelters that have become foci for Aboriginal use (site complexes). The clusters stand as islands within an archaeologically sparse sand plain. Here we investigate the distribution and patterns of use of rockshelters within 36 site clusters on the plateau. We established that their pattern of use is similar to that found in many other areas of Australia: a major site within a suite of smaller satellite sites. We also found that the quantity of rock art varies greatly between complexes, generally in proportion to the number of shelters present, and that local concentrations tend to occur where surface erosion is greatest. It is argued that, over the past 14,000 years at least, the larger rockshelters with high-motif numbers were the most frequently used and also that they lay along well-travelled pathways across the plateau. The role and uses of the smaller shelters, while clearly different from the main art shelters, remains unclear.
