SIP Security Status Quo and Future Issues

Today, the session initiation protocol (SIP) is the predominant protocol for Voice-over-IP (VoIP) signalling. The intention of this paper is to present an overview of VoIP security issues both current and future – focusing on SIP. We start by presenting some fundamental differences between VoIP and the public switched telephone network (PSTN). We then look at specific problems for SIP signalling that arise from these differences. We summarize current activities regarding SIP security, including recent developments in the research community and standardization efforts within the IETF. Finally, the paper will give an outlook on security issues in future VoIP scenarios. Specifically, we present a short security analysis of using SIP in a peer-to-peer setting (P2P-SIP).
Transitin, a nestin-like intermediate filament protein, mediates cortical localization and the lateral transport of Numb in mitotic avian neuroepithelial cells

Neuroepithelium is an apicobasally polarized tissue that contains neural stem cells and gives rise to neurons and glial cells of the central nervous system. The cleavage orientation of neural stem cells is thought to be important for asymmetric segregation of fate-determinants, such as Numb. Here, we show that an intermediate filament protein, transitin, colocalizes with Numb in the cell cortex of mitotic neuroepithelial cells, and that transitin anchors Numb via a physical interaction. Detailed immunohistological and time-lapse analyses reveal that basal Numb-transitin complexes shift laterally during mitosis, allowing asymmetric segregation of Numb-transitin to one of the daughter cells, even when the cell cleavage plane is perpendicular to the ventricular surface. In addition, RNA interference (RNAi) knockdown of the transitin gene reveals its involvement in neurogenesis. These results indicate that transitin has important roles in determining the intracellular localization of Numb, which regulates neurogenesis in the developing nervous system of avian embryos.
Heterologous Matrix Metalloproteinase Gene Promoter Activity Allows In Vivo Real-time Imaging of Bleomycin-Induced Lung Fibrosis in Transiently Transgenized Mice

Idiopathic pulmonary fibrosis is a very common interstitial lung disease derived from chronic inflammatory insults, characterized by massive scar tissue deposition that causes the progressive loss of lung function and subsequent death for respiratory failure. Bleomycin is used as the standard agent to induce experimental pulmonary fibrosis in animal models for the study of its pathogenesis. However, to visualize the establishment of lung fibrosis after treatment, the animal sacrifice is necessary. Thus, the aim of this study was to avoid this limitation by using an innovative approach based on a double bleomycin treatment protocol, along with the in vivo images analysis of bleomycin-treated mice. A reporter gene construct, containing the luciferase open reading frame under the matrix metalloproteinase-1 promoter control region, was tested on double bleomycin-treated mice to investigate, in real time, the correlation between bleomycin treatment, inflammation, tissue remodeling and fibrosis. Bioluminescence emitted by the lungs of bleomycin-treated mice, corroborated by fluorescent molecular tomography, successfully allowed real time monitoring of fibrosis establishment. The reporter gene technology experienced in this work could represent an advanced functional approach for real time non-invasive assessment of disease evolution during therapy, in a reliable and translational living animal model.
Identifying Node Importance by Combining Betweenness Centrality and Katz Centrality

The assessment of node importance has been a fundamental issue in the research of complex networks, which is of overreaching importance to improve the robustness of actual system and design efficient system structure. Most researchers use the betweenness centrality (BC) or Katz centrality (KC) to measure node importance. However, the betweenness only takes into account the shortest path, regardless of the non-shortest path. The Katz centrality gives different weights to all the paths in the network, but the ranking result is close to the result of local path index. Therefore, a new algorithm combines betweenness centrality and Katz centrality(BKC) is proposed, which considers both the local node importance and the global node importance comprehensively, and overcomes the limitations that the node importance evaluation only depending on the adjacent nodes. Experimental results on the kite network and the APRP network illustrate that BKC is more effective to find out important nodes in different types of complex networks than the algorithms compared. Moreover, the cascading failures on the author collaboration network also illustrate that the networks are more vulnerable when continuously removing the important nodes identified by BKC, which further proves the effectiveness of our method.
Adaptive output feedback control of systems preceded by the Preisach-type hysteresis

An adaptive output feedback controller is presented for a class of single-input-single-output (SISO) nonlinear systems preceded by an unknown hysteresis nonlinearity represented by the Preisach model. First, a novel model is developed to represent the hysteresis characteristic in order to handle the case where the hysteresis output is not directly measured. The model is motivated by the Preisach model but implemented by the neural networks (NN). Therefore, it is easily used for controller design. Then, a radius-basis-functional-neural-networks (RBF NN) adaptive controller based on the model estimation is presented by combining the high-gain state observer. The updated laws and control laws of the controller are derived from Lyapunov stability theorem, so that the ultimate boundedness of the closed-loop system is guaranteed. At last, an example is used to verify the effectiveness of the controller.
Peter Ingwersen, Kalervo Järvelin: The Turn. Integration of Information Seeking and Retrieval in Context

Beim Lesen des Titels, dessen recht klein geratener Untertitel zunächst gar nicht in den Blick fällt, fragt man sich, wie vermessen man sein muss, um sich selbst als Paradigmenwechsel zu stilisieren? Die Autorennamen machen deutlich, dass es sich nicht um die politische „Wende“ handelt, sondern um einen Wandel innerhalb der Disziplin der Informationswissenschaft, den man tatsächlich auch spontan mit den Namen Peter Ingwersen und Kalervo Järvelin verbinden könnte. Aber vielleicht haben Verlag und Autoren bei der Wahl des Titels sogar Recht. Es wird zumindest eine detaillierte Beschreibung dessen vorgelegt, was man in der Tat einen grundlegenden Wandel, vielleicht sogar Paradigmenwechsel der Informationswissenschaft nennen könnte.
Delayed Vomiting in Children With Cancer After Receiving Moderately High or Highly Emetogenic Chemotherapy

Delayed vomiting is a potentially significant adverse effect of chemotherapy used to treat childhood cancer, but little is known about the experience of delayed vomiting in children and adolescents. An exploratory study was conducted to determine the pattern of delayed vomiting in children and adolescents with cancer after highly emetic chemotherapy and to identify possible risk factors. In a sample of 82 children and adolescents who completed 117 cycles of highly emetic chemotherapy, the overall prevalence of delayed vomiting was 32%. The frequency of delayed vomiting was highest on delayed day 2, with 21% of participants experiencing vomiting. By delayed day 7, only 9% of participants still reported vomiting. The severity of vomiting was moderate to severe in 11% to 12% of subjects. Age and gender had no significant effect on delayed vomiting. The emetic potential of the agent, incomplete protection from acute vomiting, and treatment regimens that lasted 6 or more days significantly affected delayed vomiting. In addition, a history of motion sickness, lack of acute control, and 6 or more days of chemotherapy were predictive of delayed vomiting.
The behavior of epidemics under bounded susceptibility

We investigate the sensitivity of epidemic behavior to a bounded susceptibility constraint -- susceptible nodes are infected by their neighbors via the regular SI/SIS dynamics, but subject to a cap on the infection rate. Such a constraint is motivated by modern social networks, wherein messages are broadcast to all neighbors, but attention spans are limited. Bounded susceptibility also arises in distributed computing applications with download bandwidth constraints, and in human epidemics under quarantine policies. Network epidemics have been extensively studied in literature; prior work characterizes the graph structures required to ensure fast spreading under the SI dynamics, and long lifetime under the SIS dynamics. In particular, these conditions turn out to be meaningful for two classes of networks of practical relevance -- dense, uniform (i.e., clique-like) graphs, and sparse, structured (i.e., star-like) graphs. We show that bounded susceptibility has a surprising impact on epidemic behavior in these graph families. For the SI dynamics, bounded susceptibility has no effect on star-like networks, but dramatically alters the spreading time in clique-like networks. In contrast, for the SIS dynamics, clique-like networks are unaffected, but star-like networks exhibit a sharp change in extinction times under bounded susceptibility. Our findings are useful for the design of disease-resistant networks and infrastructure networks. More generally, they show that results for existing epidemic models are sensitive to modeling assumptions in non-intuitive ways, and suggest caution in directly using these as guidelines for real systems.

Amnesic Effects of Preacquisition, Postacquisition, or Preretrieval Tetrodotoxin Administration into the Medial Septal Area on Rat's Passive Avoidance Memorization

By means of local administration of tetrodotoxin (TTX) fully reversible functional inactivation of the medial septal area (MSA) of the rat was obtained in order to define the role of this structure in the retention of a conditioned passive avoidance response (PAR). In permanently cannulated animals, TTX (5 ng in 0.5 microl saline) or saline (0.5 microl) was injected in the MSA. TTX or saline was administered to six different groups of rats, respectively 1 h before PAR acquisition, immediately after PAR acquisition, and 1 h before PAR retrieval, performed 48 h after the acquisition trial. It was shown that MSA preacquisition and preretrieval TTX injections were followed by significant PAR retention impairment, while postacquisition TTX administration had no effect on PAR retention. The results indicate a well-defined mnemonic role of MSA during the acquisition and retrieval periods but not during the consolidation of PAR engram. The experimental evidence is discussed in relation to other reports and to MSA connectivity with other subcortical structures.
Development of a Nutrition Screening Tool for an Outpatient Wound Center

PURPOSE: To provide information on the development of a nutrition screening tool using variables believed to be predictive of malnutrition risk in the wound patient population. TARGET AUDIENCE: This continuing education activity is intended for physicians and nurses with an interest in skin and wound care. OBJECTIVES: After participating in this educational activity, the participant should be better able to: 1. Outline the variables present in patients with wounds taken into consideration when the MEAL tool was developed. 2. Identify the results of the MEAL tool pilot study. 3. List implications from this study for wound care practice. OBJECTIVE: To construct a quickly and easily administered nutrition screening tool using variables believed to be predictive of malnutrition risk in the wound patient population. DESIGN: A prospective pilot study assessed patients on a list of suspected variables, as well as the Scored Patient-Generated Subjective Global Assessment (PG-SGA), chosen as the criterion standard. Variables were analyzed to select the most appropriate items for inclusion on a new nutrition screening tool using preliminary bivariate correlations and &khgr; 2 tests of association. Items significantly associated with malnutrition were dichotomized, and binary logistic regression analyses were performed to arrive at a final model. A sum score was computed, and receiver operating characteristic analysis was used to determine designation of risk. SETTING: An outpatient wound center in Northeast Ohio. PARTICIPANTS: The pilot study included a convenience sample of 105 outpatients with at least 1 active wound. MAIN OUTCOME MEASURES: Malnutrition as assessed by the Scored PG-SGA. MAIN RESULTS: The final nutrition screening tool, the MEAL Scale, is composed of 4 dichotomous elements: multiple wounds (number of wounds), eats less than 3 meals per day, appetite decrease (eats less than usual), and level of activity. These variables predicted 83.7% of the malnutrition cases assessed by the Scored PG-SGA. The receiver operating characteristic analysis showed an acceptable area under the curve (0.8581), and a cutoff score of 2 or greater was selected to indicate risk (median sensitivity = 91.4%, median specificity = 60.9%). CONCLUSIONS: Although further studies of validity and reliability are necessary to establish the tool before widespread use, the MEAL Scale is a needed step toward nutrition screening in a wound patient population.
Women's Perceptions of Alcohol-Related Sexual Disinhibition: Personality and Sexually-Related Alcohol Expectancies

ABSTRACT Young adults frequently use alcohol prior to engaging in sexual activity (Grello, Welsh, & Harper, 2006) possibly due to expectancies relating to alcohol use and sexuality. When women engage in alcohol-use behaviors they are likely to be perceived as sexually available and promiscuous (Blume, 1991; Parks & Scheidt, 2000). The current study examined the relationships between young women's feminine gender-role attributes, erotophobia-erotophilia, and endorsement of sexually-related alcohol expectancies. Using surveys and focus groups, we investigated perceptions of the relationship between alcohol use and women's sexuality. Findings demonstrated a negative relationship between feminine gender-role and sexually-related alcohol expectancies. Free-response data indicated that sexual motives contributed to alcohol use. Participants emphasized that alcohol lowered inhibitions and increased the likelihood of engaging in sexual behaviors. Erotophobia-erotophilia influenced the pattern of qualitative response themes such that erotophobes were more likely to emphasize that alcohol contributed to increased sexual confidence and decreased nervousness.

A Structured Prediction Approach for Statistical Machine Translation

We propose a new formally syntax-based method for statistical machine translation. Transductions between parsing trees are transformed into a problem of sequence tagging, which is then tackled by a searchbased structured prediction method. This allows us to automatically acquire translation knowledge from a parallel corpus without the need of complex linguistic parsing. This method can achieve comparable results with phrase-based method (like Pharaoh), however, only about ten percent number of translation table is used. Experiments show that the structured prediction approach for SMT is promising for its strong ability at combining words.
Sequence organization and timing of bonobo mother-infant interactions

In recent years, some scholars have claimed that humans are unique in their capacity and motivation to engage in cooperative communication and extensive, fast-paced social interactions. While research on gestural communication in great apes has offered important findings concerning the gestural repertoires of different species, very little is known about the sequential organization of primates’ communicative behavior during interactions. Drawing on a conversation analytic framework, this paper addresses this gap by investigating the sequential organization of bonobo mother-infant interactions, and more specifically, how individuals solicit carries from one another. It shows how bonobos establish participation frameworks before producing a carry request gesture and how the ensuing communicative actions can be organized in adjacency-pair sequences. Moreover, the timing between the initiation of an action and its response is similar to what has been documented in adult human interaction. Finally, it outlines some of the orderly practices bonobos use to deal with the absence of response from the addressed participants in carry sequences. Keywords: adjacency pair; pan paniscus; conversation analysis; gestures; interactional time; sequence organization
Isolation and characterization of a novel venom protein from an endoparasitoid, Cotesia rubecula (Hym: Braconidae).

Insects are important vectors of diseases with remarkable immune defense capabilities. Hymenopteran endoparasitoids are adapted to overcome the host defense system and, therefore, are useful sources of immune-suppressing proteins. Not much is known about venom proteins in endoparasitoids, especially those that have a functional relationship with polydnaviruses (PDVs). Here, we describe the isolation and characterization of a small venom protein (Vn4.6) from an endoparasitoid, Cotesia rubecula, which interferes with the activation of the host hemolymph prophenoloxidase. The coding region for Vn4.6 is located upstream in the opposite direction of a gene coding for a C. rubecula PDV-protein (Crp32).
Effectiveness of feedback: the students’ perspective

While effective feedback has frequently been identified as a key strategy in learning and teaching, little known research has focused on students’ perceptions of feedback and the contribution feedback makes to students’ learning and teaching. This reported qualitative study aims to enrich our understanding of these perceptions and importantly to provide insight into the meaning of ‘effective’ when related to feedback. The study involved four focus groups of undergraduate students of varying levels and from a range of Schools completing degrees in the Faculty of Health Sciences, University of Sydney. Students’ perceptions relating to a definition of feedback, how they use it and preferences for delivery were prompted by the facilitators. Thematic analysis resulted in three key dimensions: perceptions of feedback, impact of feedback and credibility of feedback. The analysis demonstrated that effectiveness of feedback extends beyond mode of delivery and timeliness to include the credibility of the lecturer giving the feedback. The role of effective feedback includes not only enhancing learning and teaching but also facilitating the transition between school and university.
Turnaround: from breakdown to breakthrough with Open Space Technology

This interpretive case study sought to fully understand and describe the turnaround experience from an organizational breakdown to breakthrough with the use of Open Space Technology. The turnaround occurred in a Roman Catholic parish. Participant interviews were used to collect the data. These qualitative portrayals provided insights and implications around the effectiveness and impact of Open Space. Four important themes emerged: the experience of breakdown, the deep longing for a breakthrough, the transformation of crisis into a turnaround and the effectiveness of Open Space Technology. This case study provides perspectives on how to effect transformation for an organization in crisis with the least effort and maximum impact within a short time span. It contains insights and implications for leaders and consultants to do the same.
Generalisation after treatment of acquired spelling impairments: A review

This paper provides a comprehensive review of treatment studies of acquired dysgraphia and the occurrence of generalisation after this treatment. The aim is to examine what determines the occurrence of generalisation by investigating the link between the level of impairment, the method of treatment, and the outcome of therapy. We present the outcomes of treatment with regard to generalisation in 40 treatment studies. We derive general principles of generalisation which provide us with a better understanding of the mechanism of generalisation: (1) Direct treatment effects on representations or processes; (2) interactive processing and summation of activation; and (3) strategies and compensatory skills. We discuss the implications of these findings for our understanding of the cognitive processes used for spelling. Finally, we provide suggestions for the direction of further research into this important area, as a better understanding of the mechanism of generalisation could maximise treatment effects for an individual with acquired dysgraphia.
Personality disorders and eating disorders: the prevalence of personality disorders in 176 female outpatients with eating disorders

Objective: Previous research on the prevalence of personality disorders (PD) in eating disorder (ED) populations has resulted in inconsistent findings. This may be due to methodological problems such as small or selected populations, use of self-report measures and lack of formal diagnostic criteria, and to differences between populations. In the present study the prevalence of PD is assessed by structured interview in a large outpatient ED sample. Method: Consecutive female outpatients (N = 176) with eating disorders (DSM IV) were assessed by Eating Disorder Examination, Present State Examination, and Structured Clinical Interview for DSM III-R. Results: Thirty-three per cent fulfilled DSM III-R diagnostic criteria for at least one PD. Avoidant and dependent PD were the most common specific PDs. Discussion: The prevalence of PD in ED populations may not be as high as previously thought. This study shows that approximately every third ED patient fulfils criteria for at least one PD.
