The Influence of Divergent Parental Attachment Styles on Adolescent Maturation

The literature on parent–adolescent attachment relationships has proliferated in recent years and has found associations between secure, positive attachment and lower mental health difficulties, more meaningful relationships, and increased career and educational success. In contrast, those adolescents who have failed to form meaningful attachments with caregivers appear to struggle in these areas. It is important for family counselors to understand the role that attachment plays across the life span, but particularly in adolescence, as new relationships develop and relationships change. In addition, family counselors may struggle with boundary issues in counseling situations where insecure attachments are of clinical concern. Thus, this article serves as a review of the most current theory and research in the area of parent–adolescent attachment, as well as implications for family counselors—specifically, incorporating attachment into their conceptualization of cases where the adolescent is the identified client and establishing and maintaining appropriate boundaries with their adolescent clients.
Distributed Central Pattern Generator Control for a Serpentine Robot

We have built a biologically and neurally inspired autonomous mobile robotic worm. The main aim of the project is to demonstrate elegant motion on a robot with a large number of degrees of freedom (DOFs) under the control of a simple distributed neural system as found in many animals' spinal cord. Our robot consists of individually controlled segments that exhibit Central-Pattern-Generator (CPG) -driven biomorphic motion. An important aspect of the project is to achieve a level of modularity while closely mimicking the neural control of e.g., the lamprey. This paper presents our robotic platform and the distributed CPG control algorithms. We will mainly focus on the architecture of the initial system and on future developments, and also report some preliminary experimental results. Motivation
The Effects of a Self-Esteem Boost and Mortality Salience on Responses to Boost Relevant and Irrelevant Worldview Threats

Previous research found that raising self-esteem attenuates mortality salience effects on reactions to cultural worldview threats. The present study assessed whether raising self-esteem attenuates such effects when a target specifically threatened the dimension on which the boost was predicated. Participants (a) received positive personality feedback emphasizing likelihood of success either in their major or a different domain or neutral feedback, (b) contemplated their mortality or a control topic, and (c) evaluated targets threatening beliefs about the United States and the participant’s major. Replicating earlier findings, after mortality salience, neutral feedback participants derogated the anti-U.S. target, whereas positive feedback participants did not. However, if the feedback mentioned participants’ major, mortality salience led to derogation of the anti-major target, even if the feedback was positive. These findings indicate that when a target threatens a dimension on which a self-esteem boost is predicated, such a boost will not deter derogation following mortality salience.
The molecular machinery of germ line specification

Germ cells occupy a unique position in animal reproduction, development, and evolution. In sexually reproducing animals, only they can produce gametes and contribute genetically to subsequent generations. Nonetheless, germ line specification during embryogenesis is conceptually the same as the specification of any somatic cell type: germ cells must activate a specific gene regulatory network in order to differentiate and go through gametogenesis. While many genes with critical roles in the germ line have been characterized with respect to expression pattern and genetic interactions, it is the molecular interactions of the relevant gene products that are ultimately responsible for germ cell differentiation. This review summarizes the current state of knowledge on the molecular functions and biochemical connections between germ line gene products. We find that homologous genes often interact physically with the same conserved molecular partners across the metazoans. We also point out cases of nonhomologous genes from different species whose gene products play analogous biological roles in the germ line. We suggest a preliminary molecular definition of an ancestral “pluripotency module” that could have been modified during metazoan evolution to become specific to the germ line. Mol. Reprod.

An assessment of training volume in professional rugby union and its impact on the incidence, severity, and nature of match and training injuries

Abstract A prospective cohort study was used to assess the influence of training volume on injuries sustained by 502 professional rugby union players in England. Training volumes (excluding warm-ups, cool-downs, and recovery sessions), player injuries, and player match exposure times were reported weekly. Higher training volumes (>9.1 hours per week) did not increase the incidence of match or training injuries. However, higher training volumes did increase the severity of match injuries, particularly during the second half, and consequently resulted in a significant increase in the number of days' absence due to match injuries. Although lower-limb injuries were the most common match and training injuries, shoulder dislocations/instabilities resulted in more days' absence during weeks of higher training volumes, but the differences were not significant. The least number of days lost due to injuries occurred during weeks of intermediate training volumes (6.2–9.1 h per week). Training volume was not correlated with final league position. Fitness testing, defence, and rucking and mauling components were identified as being very high- or high-risk training activities. Our results provide evidence of the benefits of modifying the volume and content of rugby union training to reduce the risk associated with injuries to professional players.
Étude sur le développement des frères et sœurs d'enfants autistes

Cet article presente les premieres conclusions d’une recherche qui tend a etudier le processus de developpement des freres et sœurs d’enfants autistes, afin d’en analyser les difficultes. On part de l’hypothese psychanalytique qu’un sujet se construit au travers de la relation pulsionnelle qu’il etablit avec l’Autre. Quand cette relation pulsionnelle avec l’Autre ne se met pas en place, nous pouvons constater une difficulte dans la constitution du sujet. L’autisme est la consequence de la non-installation de ce lien due a plusieurs facteurs. On suppose que dans la fratrie des enfants autistes nous pouvons rencontrer des entraves pour l’installation de ce lien. Pour verifier cette hypothese, nous utilisons les indicateurs cliniques de risques pour le developpement infantile (IRDI) et les signes du Programme de recherche sur l’autisme (PREAUT) afin d’analyser six vignettes cliniques de freres et sœurs d’enfants autistes.
Communicative Framing Theory in Conflict Resolution

This article evaluates the framing concept and its utility for communication research in conflict resolution. The framing concept holds potential heuristic value that has not been realized. The authors take three rehabilitative steps: (a) define frames as communicative, rather than cognitive, constructions, (b) provide a theoretical framework for explicating the communicative framing process and its potential impact in conflict, and (c) explore the effects of particular framing patterns on actual conflict interaction. The framing concept is enhanced through alignment with negotiated order theory, speech act theory, and speech accommodation theory. It is argued that disputants and the professionals who work with them “frame” issues, using language choices to highlight some aspects of an issue, while ignoring others. Linguistic choices function as verbal cues to other participants, who may respond by converging or diverging on frames. As expected, the results of the study found a positive relationship between frame convergence and frequency of agreements. Negotiators and mediators who guided disputant discussion toward frame convergence increased focus, control, positive social attributions, and integrativeness.
The hidden number problem with nonprime modulus

Abstract We consider a generalization of the Hidden Number Problem for general moduli N , and prove that it can be solved with high probability if roughly 2(logN) aproximations of quality at least (log N) are given, and the multipliers are chosen uniformly at random from ZZ/NZZ. We prove a similar result in the case that the multipliers are chosen uniformly at random from (ZZ/NZZ) and N is the product of two distinct primes. The last result holds in the more general case when N is squarefree and a technical condition related to the prime factors of N holds. The condition is related to the distribution of the solutions of a linear equation modulo N . The Hidden Number Problem modulo the product of two primes, with multipliers chosen from (ZZ/NZZ), is related to the bit security of the most significant bits of the RSA and Rabin functions. Our solution of the Hidden Number Problem implies that computing roughly (log(N)) bits of the RSA and Rabin functions is equivalent to computing the entire values.
The Therapeutic Potential of Intraoperative Hypercapnia During Video-Assisted Thoracoscopy in Pediatric Patients

BACKGROUND:Although the cardiovascular effect of CO2 insufflation has not been reported in pediatric thoracoscopy, several clinical trials have demonstrated significant hemodynamic deterioration in adults. We investigated the concept of therapeutic hypercapnia for counteracting the hemodynamic effect of induced capnothorax. METHODS:Twelve pediatric patients who underwent video-assisted thoracoscopic patent ductus arteriosus closure were enrolled in the study. Cardiorespiratory variables were determined during baseline T1 and after CO2 insufflation at pressures of 2 mm Hg T2, 4 mm Hg T3, 6 mm Hg T4, 8 mm Hg T5, and 10 mm Hg T6. RESULTS:CO2 insufflation was not associated with any adverse hemodynamic effects. Cardiac output and central venous oxygen saturation increased progressively throughout the study protocol. Relative to baseline peak velocity, systolic flow time corrected for heart rate, heart rate, and central venous pressure increased significantly during insufflation, but systolic and diastolic blood pressure remained unchanged. Arterial CO2 increased from 40.7 ± 3 at T1 to 61 ± 1.6 at T6 mm Hg. Arterial oxygen tension increased from 170.9 ± 3.3 at T1 to 182 ± 2 at T6; arterial PH decreased from 7.31 ± 1.2 at T1 to 7.14 ± 4.6 at T6. CONCLUSION:Hypercapnia targeting CO2 50–70 mm Hg was associated with increased cardiac output, central venous O2, and arterial O2 tension in patients undergoing video-assisted thoracoscopic patent ductus arteriosus closure using one-lung ventilation without any deleterious cardiopulmonary effects.
Discrete Physics: a new way to look at cryptography

This paper shows that Physics is very close to the substitution-diffusion paradigm of symmetric ciphers. Based on this analogy, we propose a new cryptographic algorithm. Statistical Physics gives design principles to devise fast, scalable and secure encryption systems. In particular, increasing space dimension and considering larger data blocks improve both speed and security, allowing us to reach high throughput (larger than 10Gb/s on dedicated HW). The physical approach enlarges the way to look at cryptography and is expected to bring new tools and concepts to better understand and quantify security aspects.
Lingual kinematic strategies used to increase speech rate: Comparison between younger and older adults

The primary objective of this study was to assess the lingual kinematic strategies used by younger and older adults to increase rate of speech. It was hypothesised that the strategies used by the older adults would differ from the young adults either as a direct result of, or in response to a need to compensate for, age‐related changes in the tongue. Electromagnetic articulography was used to examine the tongue movements of eight young (M = 26.7 years) and eight older (M = 67.1 years) females during repetitions of /ta/ and /ka/ at a controlled moderate rate and then as fast as possible. The younger and older adults were found to significantly reduce consonant durations and increase syllable repetition rate by similar proportions. To achieve these reduced durations both groups appeared to use the same strategy, that of reducing the distances travelled by the tongue. Further comparisons at each rate, however, suggested a speed‐accuracy trade‐off and increased speech monitoring in the older adults. The results may assist in differentiating articulatory changes associated with normal aging from pathological changes found in disorders that affect the older population.
Patterns, frameworks, and middleware: their synergistic relationships

The knowledge required to develop complex software has historically existed in programming folklore, the heads of experienced developers, or buried deep in the code. These locations are not ideal since the effort required to capture and evolve this knowledge is expensive, time-consuming, and error-prone. Many popular software modeling methods and tools address certain aspects of these problems by documenting how a system is designed However they only support limited portions of software development and do not articulate why a system is designed in a particular way, which complicates subsequent software reuse and evolution. Patterns, frameworks, and middleware are increasingly popular techniques for addressing key aspects of the challenges outlined above. Patterns codify reusable design expertise that provides time-proven solutions to commonly occurring software problems that arise in particular contexts and domains. Frameworks provide both a reusable product-line architecture [1] - guided by patterns - for a family of related applications and an integrated set of collaborating components that implement concrete realizations of the architecture. Middleware is reusable software that leverages patterns and frameworks to bridge the gap between the functional requirements of applications and the underlying operating systems, network protocol stacks, and databases. This paper presents an overview of patterns, frameworks, and middleware, describes how these technologies complement each other to enhance reuse and productivity, and then illustrates how they have been applied successfully in practice to improve the reusability and quality of complex software systems.
Malaria vaccine study site in Irian Jaya, Indonesia: Plasmodium falciparum incidence measurements and epidemiologic considerations in sample size estimation.

Malaria epidemiologic and entomologic studies were performed during both the high transmission and low transmission seasons to characterize the Plasmodium falciparum malaria transmission at a proposed malaria vaccine trial site in Irian Jaya, Indonesia. The study population consisted of two subsets: native Irianese men with lifelong exposure to malaria and transmigrants who arrived from a nonmalarious area 2.5 years before the start of the study. All subjects received a radical cure for malaria and were then monitored weekly by blood film. Both P. falciparum malaria attack rates and incidence densities were calculated; transmigrants had a significantly higher rate (P = 0.003) than the Irianese during the low transmission season study (20-weeks long) but not during the high transmission season study (12-weeks long). Lack of exposure-induced immunity left the transmigrants at a minimum 17-25% greater relative risk of becoming parasitemic compared with the Irianese during the low transmission season study. During the high transmission season study, 50% of the transmigrants were P. falciparum positive by week 6 and 50% of the Irianese by week 9. During the low transmission season, 50% of the transmigrants were positive by week 10 and 43% of the Irianese were positive by week 17. Entomologic studies showed that Anopheles koliensis was the predominant vector (> 98% of anopheline catch). Entomologic inoculation rates for P. falciparum were 0.018 and 0.39 infective bites/person/night for the low and high transmission seasons, respectively. New P. vivax cases represented between 16% and 42% of all initial malaria cases. (ABSTRACT TRUNCATED AT 250 WORDS)
Sexual and aggressive play fighting of sibling Richardson’s ground squirrels

Play fighting in many species of squirrels can involve sexual play and aggressive play, both of which can lead to wrestling which appears superficially similar. Such convergence can make scoring of the relative frequencies of these two types of play difficult and can lead to the mistaken conclusion that they grade into one another. In this study, both staged laboratory encounters between sibling pairs and spontaneous encounters between siblings in free-living litters of Richardson’s ground squirrels (Spermophilus richardsonii) were videotaped. Frame-by-frame analyses using the Eshkol-Wachman Movement Notation were employed to record the correlated movements of attack and defense by the partners and to reveal the body areas targeted during each play bout. Whereas sexual play was organized around access to the rump, aggressive play was organized around the shoulders. Although in most cases the defender’s tactics blocked access to the respective target, when contact did occur, it involved mounting in sexual play and nosing or biting in aggressive play. Eighty-six percent of play fights could be unambiguously categorized as either sexual or aggressive play. Of these, the majority (˜80%) involved sexual play. The sex of the participants did not affect the frequency of aggressive play, but in sexual play, males initiated more attacks than females. Once initiated, each form of play fighting remained distinct—if a bout began as sexual play, it would end as sexual play. Furthermore, a counterattack following sexual play was significantly more likely to be sexual than aggressive, and vice versa for counterattacks following aggressive play. Therefore, all the evidence suggested that the two forms of play fighting were not intermixed in Richardson’s ground squirrels. Aggr. Behav. 27:323–337, 2001. © 2001 Wiley-Liss, Inc.
A Methodology for Direct and Indirect Discrimination Prevention in Data Mining

Data mining is an increasingly important technology for extracting useful knowledge hidden in large collections of data. There are, however, negative social perceptions about data mining, among which potential privacy invasion and potential discrimination. The latter consists of unfairly treating people on the basis of their belonging to a specific group. Automated data collection and data mining techniques such as classification rule mining have paved the way to making automated decisions, like loan granting/denial, insurance premium computation, etc. If the training data sets are biased in what regards discriminatory (sensitive) attributes like gender, race, religion, etc., discriminatory decisions may ensue. For this reason, anti-discrimination techniques including discrimination discovery and prevention have been introduced in data mining. Discrimination can be either direct or indirect. Direct discrimination occurs when decisions are made based on sensitive attributes. Indirect discrimination occurs when decisions are made based on nonsensitive attributes which are strongly correlated with biased sensitive ones. In this paper, we tackle discrimination prevention in data mining and propose new techniques applicable for direct or indirect discrimination prevention individually or both at the same time. We discuss how to clean training data sets and outsourced data sets in such a way that direct and/or indirect discriminatory decision rules are converted to legitimate (nondiscriminatory) classification rules. We also propose new metrics to evaluate the utility of the proposed approaches and we compare these approaches. The experimental evaluations demonstrate that the proposed techniques are effective at removing direct and/or indirect discrimination biases in the original data set while preserving data quality.
Optimization of duty cycles for LED based indoor positioning system

In this paper, an optimal duty cycle, which increases packet delivery ratio (PDR) and reduces probability of collision is designed for packet transmission in an indoor positioning system based on a multiple LED estimation model (MLEM). MLEM improves positioning accuracy by identifying positions of overlap regions where light footprints from multiple LEDs. In MLEM, asynchronous LED transmitters send positional information at the same frequency, amplitude, and wavelength. Consequently, in an LED overlap region, transmitted packets collide and therefore are lost. Methods to avoid packet collision in this region are considered and based on keeping the hardware simple, packet-based pulse duration multiplexing is optimized to provide a time based pseudo-orthogonality between packets. Initial experiments showed a PDR of 0.5 in the overlap region. However, by defining the boundary conditions for non-persistent packet collisions, an exhaustive search for the optimal packet transmission configuration is carried out in this work. Results show that the optimum points occur at 0.09 and 0.1 duty cycles. The use of this optimal duty cycles improved PDR to 0.9 for transmission in the overlap region.
A data-driven simulation of social values evolution

Modelling the evolution of moral values in a society is a complex problem that involves many interwined aspects. The approach presented in this paper takes information from a common tool of sociologists, public surveys, as input to build the model by following a data-driven approach, to analyse and interpret the impact of each factor separately, and their mutual influence. The system handles thousands of heterogeneous agents, with their own life cycle, reproduction patterns and complex social relationship dynamics including friendship. The emergence of a robust social network was a consequence of the system set up. Its output is consistent with respect to the ideological, religious and demographic parameters observed in real world surveys.
D ec 2 00 1 Self-Adjunctions and Matrices

It is shown that the multiplicative monoids of Temperley-Lieb algebras are isomorphic to monoids of endomorphisms in categories where an endofunctor is adjoint to itself. Such a self-adjunction is found in a category whose arrows are matrices, and the functor adjoint to itself is based on the Kronecker product of matrices. Thereby one obtains a representation of braid groups in matrices, which, though different and presumably new, is related to the standard representation of braid groups in Temperley-Lieb algebras.

Practical parallel processing with transputers

This paper explores methods for extracting parallelism from a wide variety of numerical applications. Load-balancing considerations and communication overheads for implementing scientific and engineering problems on networks of transputers are then discussed. Some case studies are presented in detail. The paper demonstrates that reconfigurable transputer arrays provide a flexible, powerful and easily programmable approach to parallel processing.
