The influence of past behavior on behavioral intent: An information‐processing explanation
Authors: Kidwell Blair , Jewell Robert D. 
Published: November 2008

AbstractDespite considerable research on the impact of past behavior on decision making over the past two decades, little is yet known about how past experience moderates decision theoretic factors within models of behavioral intent. This research explores the implications of past behavior within the theory of planned behavior (TPB), and how it influences key decision‐making variables. A theoretical model of how past behavior can induce deliberative versus heuristic processing of information is developed and tested. Consumer implications of the impact of past behavior on behavioral intentions are discussed, highlighting the importance of addressing one's experience when making a decision. © 2008 Wiley Periodicals, Inc.
Vertical stress distributions around batter piles driven in cross‐anisotropic media
Authors: Wang Cheng‐Der , Lee Tzen‐Chin , Chen Ming‐Tang 
Published: November 2008

AbstractThis work presents analytical solutions to compute the vertical stresses for a cross‐anisotropic half‐space due to various loading types by batter piles. The loading types are an embedded point load for an end‐bearing pile, uniform skin friction, and linear variation of skin friction for a friction pile. The cross‐anisotropic planes are parallel to the horizontal ground surface. The proposed solutions can be obtained by utilizing Wang and Liao's solutions for a horizontal and vertical point load acting in the interior of a cross‐anisotropic medium. The derived cross‐anisotropic solutions using a limiting approach are in perfect agreement with the isotropic solutions of Ramiah and Chickanagappa with the consideration of pile inclination. Additionally, the present solutions are identical to the cross‐anisotropic solutions by Wang for the batter angle equals to 0. The influential factors in yielded solutions include the type and degree of geomaterial anisotropy, pile inclination, and distinct loading types. An example is illustrated to clarify the effect of aforementioned factors on the vertical stresses. The parametric results reveal that the stresses considering the geomaterial anisotropy and pile batter differ from those of previous isotropic and cross‐anisotropic solutions. Hence, it is imperative to take the pile inclination into account when piles are required to transmit both the axial and lateral loads in the cross‐anisotropic media.

Rotational kinematic hardening model for three‐dimensional stress reversals in sand
Authors: Lade Poul V. , Yamamuro Jerry A. , Gutta Suresh K. 
Published: November 2008

AbstractA kinematic hardening mechanism has previously been proposed to capture the behavior of soil during large stress reversals in the triaxial plane. This mechanism is now extended to the principal stress space. It incorporates rotation and intersection of yield surfaces to achieve a consistent and physically rational fit with experimentally observed soil behavior during large three‐dimensional stress reversals. An existing elasto‐plastic model with isotropic hardening is used as the basic framework to which the rotational kinematic hardening mechanism has been added. The new combined model preserves the behavior of the isotropic hardening model under monotonic loading conditions, and the extension from isotropic to rotational kinematic hardening under three‐dimensional conditions is accomplished without introducing new material parameters. The framework of the model is presented here with some comparisons between theoretical and experimental directions of strain increment vectors to indicate the potential of the model.

An elastoplastic strainhardening model for soil allowing for hydraulic bonding–debonding effects
Authors: Buscarnera Giuseppe , Nova Roberto 
Published: November 2008

AbstractThe paper presents a strainhardening constitutive model for unsaturated soil behaviour based on energy conjugated stress variables in the framework of superposed continua. The proposed constitutive law deals with hydro‐mechanical coupling phenomena. The main purpose is to develop within a consistent framework a model that can deal with possible mechanical instabilities occurring in partially saturated materials. The loss of capillary effects during wetting processes can, in fact, play a central role in unstable processes. Therefore, it will be shown that the bonding effects due to surface tensions can be described in a mathematical framework similar to that employed for bonded geomaterials to model weathering or diagenesis effects, either mechanically or chemically induced. The results of several simulations of common laboratory tests on partially saturated soil specimens are shown. The calculated behaviour appears to be in good qualitative agreement with that observed in the laboratory. In particular it is shown that volumetric collapse phenomena due to hydraulic debonding effects can be successfully described by the model. Finally, it will be highlighted the ability of the model to naturally capture the transition to a fully saturated condition and to deal with possible mechanical instabilities in the unsaturated regime.

An innovative approach to identify the IP address in denial‐of‐service (DoS) attacks based on Cauchy's integral theorem
Authors: Viana Mateus Mosca , Rios Riverson , de Castro Andrade Rossana Maria , de Souza José Neuman 
Published: November 2008

AbstractDenial‐of‐service (DoS) and distributed denial‐of‐service (DDoS) are two of the most severe attacks against computer networks, especially the Internet. Despite its destructive effect, planning these attacks is a feasible task. Given that most attackers usually spoof the source address in packet headers, countermeasures can be based on two steps. First of all, some information from the attack space of the offender must be gathered. Fortunately, packets that reach a victim carry important data that can be acquired by means of a data collection process. One possibility is to use the probabilistic packet marking (PPM) approach for data acquisition. Once this is achieved, the next step consists of reconstructing the attack path, which can be carried out by several methods available in the literature. However, none of them provides a precise solution. In this paper, a new theoretical tracking model for the identification of DoS attackers is presented. The model unites the PPM approach and the concept of winding number, derived from the well‐known Cauchy's integral theorem. The winding number is a hydraulic analogy of the amount of attacking packets growing from a router. A suitable transformation allows seeing the packet traffic, in the attack environment, as a fluid flux in the space of complex variables. The method of solving the tracking problem and identifying the sources of attack presents an additional motivation: the use of continuous techniques when approaching a problem that occurs in a discrete environment. Such association will contribute to the development of further solutions possibly more robust than the one dealt with here. This paper shows that the new model can correctly identify the IP address of the router from which the attack comes by using an integral equation derived from the winding number expression.

Published: November 2008

AbstractThe anti‐Hu syndrome is a well‐known paraneoplastic syndrome and may be rarely seen in patients with neuroblastoma. However, it is relatively unknown that anti‐Hu antibodies can cause gastro‐intestinal signs and symptoms. We report on a child with neuroblastoma who presented with gastro‐intestinal disturbances as a result of the anti‐Hu syndrome and summaries two similar case reports reported in literature. Neuroblastoma patients with gastro‐intestinal disturbances, ranging from constipation to a paralytic ileus, might suffer from the gastro‐intestinal anti‐Hu syndrome. The causative antibodies can be determined to diagnose or exclude this syndrome, and successful treatment is possible. Pediatr Blood Cancer 2009;52:396–398. © 2008 Wiley‐Liss, Inc.

Published: November 2008

AbstractObjectiveAcute lymphoblastic leukemia (ALL) with high‐risk features has an inferior outcome. Factors influencing the treatment and outcome of pediatric ALL with high‐risk features in developing countries have not been well studied.MethodsHigh‐risk features were defined as: age <1 year or >10 years, white blood cell (WBC) > 50 × 109/L, CNS or testicular involvement at diagnosis, T‐ALL, BCR‐ABL/MLL‐AF4, poor prednisone response, slow early response to induction chemotherapy which was defined as M3 status (>25% blasts) on day 15 bone marrow with age >6 years or presenting WBC > 20 × 109/L at diagnosis and/or non‐remission (NR) after 33 days of induction therapy.ResultsNinety‐one children were analyzed. The total rate of treatment abandonment was 24.2% and treatment‐related mortality was 3.3% (3/91). The event‐free survival (EFS) was 52.3% (95% CI, 41.5–63.1%) at 4 years and 49.9% (95% CI, 38.9–60.9%) at 8 years, respectively. When the cases who abandoned treatment were excluded, the EFS of the remainder was 68.3% (95% CI, 56.5–80.1%) at 4 years and 65.2% (95% CI, 52.5–77.9%) at 8 years, respectively. NR on day 33 or BCR‐ABL remained as an independent unfavorable prognostic factor in the Cox model even if more intense chemotherapy was administrated.ConclusionA decreased treatment‐related death frequency was associated with an improved outcome of leukemia. This emphasizes the importance of improving supportive care in developing countries for children with high‐risk ALL who receive very intensive chemotherapy. Treatment abandonment remains a prominent reason for treatment failure in China. Pediatr Blood Cancer 2009;52:191–195. © 2008 Wiley‐Liss, Inc.

AbstractBackgroundThe presence of metabolically important genetic polymorphisms may affect treatment efficacy in patients with malignancies. The objective of this prospective multicenter study was to evaluate the role of selected polymorphisms of genes associated with metabolism of chemotherapeutic drugs as prognostic markers in children with acute lymphoblastic leukemia.ProcedureGenotyping for the presence of 7 genetic variants in 403 patients and analysis of death cases were performed.ResultsThirty‐one children died before reaching remission maintenance phase. Genetic analysis revealed in this group increased frequency of homozygosity for c.677C>T polymorphism of the MTHFR gene (26% vs. 8% in the survivors; OR 4.09; 95% CI 1.67–10; adjusted for multiple testing P = 0.028).ConclusionOur data suggest that modification of anti‐leukemic treatment should be considered in patients homozygous for c.677C>T polymorphism.

Authors: Geller James I. , Wall Donna , Perentesis John , Blaney Susan M. , Bernstein Mark 
Published: November 2008

AbstractPurposeA dose‐escalation Phase I study of taxol (paclitaxel) administered in combination with standard dose ifosfamide was conducted in children with relapsed or refractory solid tumors. Primary objectives were to estimate the maximum tolerated dose (MTD) and to describe the dose‐limiting toxicities (DLTs).Patients and MethodsPaclitaxel was administered as a 6‐hr continuous infusion (hr 0–6), followed by intravenous ifosfamide (2 g/m2/day × 3 days) over 1 hr at hours 6–7, 24–25, and 48–49. Patients at dose level 1 received 250 mg/m2 paclitaxel. Subsequent dose escalation proceeded using a standard 3 × 3 Phase I design.ResultsFifteen patients received a combined 46 courses of therapy. The median age was 14.5 years (range, 2–19 years), and diagnoses included sarcoma (7), neuroblastoma (3), and other (5). Three patients received paclitaxel at 250 mg/m2 (10 courses), six at 325 mg/m2 (19 courses), three at 425 mg/m2 (8 courses), and three at 550 mg/m2 (9 courses). DLTs occurred in 2/3 patients at 550 mg/m2 paclitaxel during cycle 1, including grade 3 hypotension and grade 4 anaphylaxis in 1 patient each. Common non‐dose‐limiting toxicities included bone marrow suppression and peripheral neuropathy. Response was evaluable in 14 patients and included mixed response (3), stable disease (5), and progressive disease (6).ConclusionPaclitaxel hypersensitivity reactions were dose limiting when the drug was administered as a 6‐hr infusion. The MTD and recommended Phase II dose of paclitaxel administered as a 6‐hr continuous intravenous infusion followed by standard dose intravenous ifosfamide is 425 mg/m2 paclitaxel.

Published: November 2008

AbstractJuvenile xanthogranulomatosis (JXG) is an uncommon histiocytic disease that is usually limited to the skin. Here we describe an infant with systemic JXG including a central nervous system (CNS) lesion. He was initially treated with prednisolone and vinblastine but developed an idiosyncratic reaction to prednisolone that was discontinued. The lesion then failed to respond to vinblastine monotherapy. Treatment with cladribine (2‐chlorodeoxyadenosine) was subsequently successful with radiological resolution of the CNS lesion. Pediatr Blood Cancer 2009;52:413–415. © 2008 Wiley‐Liss, Inc.
Transient myeloproliferation mimicking JMML associated with parvovirus infection of infancy
Authors: Gupta Nidhi , Gupta Ritu , Bakhshi Sameer 
Published: November 2008

AbstractWe report a 2‐month‐old infant with Parvovirus B19 infection presenting as transient myeloproliferation resembling juvenile myelomonocytic leukemia (JMML). Patient history, physical examination, and laboratory findings were suggestive of JMML. On viral serology, raised IgM and IgG titers for Parvovirus B19 infection were found in the absence of giant proerythroblasts and viral inclusions in the erythroid precursors. Follow‐up showing a decrease in viral titers suggested parvovirus infection as an etiological factor for the development of myeloproliferative features. This case highlights the importance of viral serology in work‐up myeloproliferative disorders of infancy and childhood. Pediatr Blood Cancer 2009;52:411–413. © 2008 Wiley‐Liss, Inc.

AbstractCombined quantum mechanical/molecular mechanical (QM/MM) techniques have been applied to investigate the detailed reaction mechanism of the first step of the acylation process by furin in which the cleavage site of the highly pathogenic avian influenza virus subtype H5N1 (HPH5) acts as its substrate. The energy profile shows a simultaneous mechanism, known as a concerted reaction, of the two subprocesses: the proton transfer from Ser368 to His194 and the nucleophilic attack on the carbonyl carbon of the scissile peptide of the HPH5 cleavage site with a formation of tetrahedral intermediate (INT). The calculated energy barrier for this reaction is 16.2 kcal·mol−1 at QM/MM B3LYP/6‐31+G*//PM3‐CHARMM22 level of theory. Once the reaction proceeds, the ordering of the electrostatic stabilization by protein environment is of the enzyme‐substrate < transition state < INT complexes. Asp153 was found to play the most important role in the enzymatic reaction by providing the highest degree of intermediate complex stabilization. In addition, the negatively charged carbonyl oxygen of INT is well stabilized by the oxyanion hole constructed by Asn295's carboxamide and Ser368's backbone. Proteins 2009. © 2008 Wiley‐Liss, Inc.
Does sustainability count? Environmental policy, sustainable development and the governance of grassroots sustainability enterprise in Ireland
Authors: Davies Anna Ray 
Published: November 2008

AbstractEnvironmentally focused social economy activities have been identified as archetypal examples of sustainable development: what might be called grassroots sustainability enterprises. The economic, social and environmental benefits that they can offer have been alluded to, but little empirical evaluation has been conducted examining the governing conditions under which they emerge or the impacts they engender. In response this paper investigates the experiences of one arena of grassroots sustainability enterprise in Ireland, community based recycling organizations (CBROs). The research found that the tripartite focus of CBROs on economic development, environmental enhancement and social capacity building can be problematic rather than bringing enhanced status. Building on an analysis of national planning documents it is proposed that such problems emerge as dominant governing conditions are pursuing ecological modernization and social partnership as distinct rather than integrated pathways of development.

LAID: a learning automata‐based scheme for intrusion detection in wireless sensor networks
Authors: Misra Sudip , Abraham Kiran Isaac , Obaidat Mohammad S. , Krishna P. Venkata 
Published: November 2008

AbstractIn this paper, we address the problem of intrusion detection in wireless sensor networks (WSNs) using a learning automata (LA)‐based approach. We are not aware of any LA‐based intrusion detection systems (IDSs) for WSN. Additionally, the S‐model approach that we have taken to solve the problem, wherein the feedback of the environment to the automaton can not only be completely favorable or completely unfavorable, but also be any continuous value within these extremities, makes it one of the attractive solution approaches in LA. We have rigorously evaluated the performance of our proposed solution by performing a variety of experiments and have found our solution approach to be promising.

DynaQoS©‐RDF: a best effort for QoS‐assurance of dynamic reconfiguration of dataflow systems
Authors: Li Wei 
Published: November 2008

AbstractThe significance of QoS‐assurance is being increasingly recognized by both the research and wider communities. In the latter case, this recognition is driven by the increasing adoption by business of 24/7 software systems and the QoS decline that end‐users experience when these systems undergo dynamic reconfiguration. At the beginning of 2006, the author set up a project named DynaQoS©‐RDF (QoS‐assurance of Dynamic Reconfiguration on Reconfigurable Dataflow Model), which was then sponsored by the CQ University Australia. Over the last two years, the author has investigated QoS‐assurance for dataflow systems, which are characterized by the pipe‐and‐filter architecture. The research has addressed issues such as: the global consistency of protocol transactions, the necessary and sufficient conditions for QoS‐assurance, execution overhead control for reconfiguration, state transfer for stateful components, and the design of a QoS benchmark. This paper discusses these research issues. It also proposes various QoS strategies and presents a benchmark for evaluating QoS‐assurance strategies for the dynamic reconfiguration of dataflow systems. This benchmark is implemented using the DynaQoS©‐RDF v1.0 software platform. Various strategies, including those from the research literature are benchmarked, and the best efforts for QoS‐assurance are identified. Copyright © 2008 John Wiley & Sons, Ltd.

Published: November 2008

AbstractDiacylglycerol (DAG) supplementation has been shown to be associated with the reduction of postprandial triacylglycerol (TAG) concentration, although the extent of the association is uncertain. We quantitatively examined the effect of dietary DAG on postprandial serum TAG concentration by conducting a meta‐analysis of randomized controlled trials. Potential papers were initially searched for in the electronic databases of Medline, Embase and Cochrane library. Inclusion criteria required the trial to be randomized with DAG as the treatment group, and TAG as the control group. Information was extracted independently by two investigators and the effect of DAG on postprandial TAG concentration was examined in Review Manager 4.2. Seven papers were included in the statistic pooling. DAG supplementation reduced the increment of postprandial TAG concentration significantly at postprandial 2 h (Weighted mean difference (WMD) −0.07 mmol/L; 95% CI −0.13 to 0.00 mmol/L; P = 0.05), 4 h (WMD −0.15 mmol/L; 95% CI −0.24 to −0.06 mmol/L; P = 0.002) and 6 h (WMD −0.14 mmol/L; 95% CI −0.23 to −0.05 mmol/L; P = 0.002). Linear regression showed that the effect of DAG was positively correlated with the daily dosage at 2 h (P = 0.095) and 6 h (P = 0.053) after lipid loading. In conclusion, compared with TAG oil, DAG reduced the postprandial serum TAG concentration at 2 h, 4 h and 6 h postprandial and was positively correlated with daily dosage.
Crystallization Kinetics of Cocoa Fat Systems: Experiments and Modeling
Authors: Padar S. , Jeelani S. A. K. , Windhab E. J. 
Published: November 2008

AbstractIsothermal crystallization kinetics of unseeded and seeded cocoa butter and milk chocolate is experimentally investigated under quiescent conditions at different temperatures in terms of the temporal increase in the solid fat content. The theoretical equations of Avrami based on one‐, two‐ and three‐dimensional crystal growth are tested with the experimental data. The equation for one‐dimensional crystal growth represents well the kinetics of unseeded cocoa butter crystallization of form α and β′. This is also true for cocoa butter crystal seeded milk chocolate. The sterical hindrance due to high solids content in chocolate restricts crystallization to lineal growth. In contrast, the equation for two‐dimensional crystal growth fits best the seeded cocoa butter crystallization kinetics. However, a transition from three‐ to one‐dimensional growth kinetics seems to occur. Published data on crystallization of a single component involving spherulite crystals are represented well by Avrami’s three‐dimensional theoretical equation. The theoretical equations enable the determination of the fundamental crystallization parameters such as the probability of nucleation and the number density of nuclei based on the measured crystal growth rate. This is not possible with Avrami’s approximate equation although it fits the experimental data well. The crystallization can be reasonably well defined for single component systems. However, there is no model which fits the multicomponent crystallization processes as observed in fat systems.
