The Incremental Validity of Passive-Aggressive Personality Symptoms Rivals or Exceeds That of Other Personality Symptoms in Suicidal Outpatients

We examined the incremental validity of passive-aggressive and other personality symptoms, by determining personality syndromes' ability to account for unique variance in distress and impairment as indexed by several Axis I-related symptoms. Two hundred fifty young adults, referred for suicidal behavior or ideation, completed the Millon Clinical Multiaxial Inventory (Millon, 1983) as well as several other symptom measures. The personality syndromes varied considerably in their ability to account for unique variance in Axis I-related symptoms. Several syndromes, including schizoid, schizotypal, and compulsive symptoms, showed relatively low incremental validity, whereas the incremental validity of passive-aggressive symptoms exceeded all others. The criterion of incremental validity represents an inclusive and persuasive means to evaluate personality disorder validity. On this criterion, passive-aggressive symptoms display high validity, and passive-aggressive personality disorder, in some form, may deserve inclusion on Axis II of future editions of Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association).
Effect of Surface Tangential Contact Stresses on Flexible Pavement Response (With Discussion)

The objective of this study was to investigate the responses of flexible pavement to continuously moving vehicular loading under various tire configurations. Measured vertical and surface tangential contact stresses (longitudinal and horizontal) were incorporated into a three-dimensional (3D), finite element (FE) model. Results from the developed 3D FE model were successfully verified against field measurements. The predicted peak strains were comparable to the field-measured values. The study found that pavement responses at the surface and shallow interface were clearly affected by surface tangential stresses. In addition, the study found that surface tensile strains vary notably between the tire’s rib and groove. When horizontal, surface tangential stresses are incorporated, there is increased potential for the development of surface-initiated, top-down cracking in the pavement surface close to a tire’s edge. Because horizontal tangential stress can be as high as about 52% of the compressive vertical stress, it must be included in flexible pavement analysis. This will result in improving the prediction of pavement responses to vehicular loading, especially at shallow depth.
DSybil: Optimal Sybil-Resistance for Recommendation Systems

Recommendation systems can be attacked in various ways, and the ultimate attack form is reached with a {\em sybil attack}, where the attacker creates a potentially unlimited number of {\em sybil identities} to vote. Defending against sybil attacks is often quite challenging, and the nature of recommendation systems makes it even harder. This paper presents {\em DSybil}, a novel defense for diminishing the influence of sybil identities in recommendation systems. DSybil provides strong provable guarantees that hold even under the worst-case attack and are optimal. DSybil can defend against an unlimited number of sybil identities over time. DSybil achieves its strong guarantees by i) exploiting the heavy-tail distribution of the typical voting behavior of the honest identities, and ii) carefully identifying whether the system is already getting ``enough help'' from the (weighted) voters already taken into account or whether more ``help'' is needed. Our evaluation shows that DSybil would continue to provide high-quality recommendations even when a million-node botnet uses an optimal strategy to launch a sybil attack.
NURSES ON A MISSION: A Professional Service Learning Experience with the Inner-City Homeless

Nursing students can play a vital role in addressing the health care needs of the homeless. Through professional service learning experiences in community-based settings, students learn how to partner with key community leaders and agencies to meet the needs of underserved populations and provide culturally competent care to diverse populations. This article describes the development of a professional service learning experience with the homeless in which a community-academic partnership was created to meet community needs. In an era of declining health care resources, such innovative partnerships serve to reduce health disparities and improve access to care while preparing students for community-based practice with at-risk and vulnerable populations.
Stroke vision, aphasia, neglect (VAN) assessment—a novel emergent large vessel occlusion screening tool: pilot study and comparison with current clinical severity indices

Background Identification of emergent large vessel occlusion (ELVO) stroke has become increasingly important with the recent publications of favorable acute stroke thrombectomy trials. Multiple screening tools exist but the length of the examination and the false positive rate range from good to adequate. A screening tool was designed and tested in the emergency department using nurse responders without a scoring system. Methods The vision, aphasia, and neglect (VAN) screening tool was designed to quickly assess functional neurovascular anatomy. While objective, there is no need to calculate or score with VAN. After training participating nurses to use it, VAN was used as an ELVO screen for all stroke patients on arrival to our emergency room before physician evaluation and CT scan. Results There were 62 consecutive code stroke activations during the pilot study. 19 (31%) of the patients were VAN positive and 24 (39%) had a National Institutes of Health Stroke Scale (NIHSS) score of ≥6. All 14 patients with ELVO were either VAN positive or assigned a NIHSS score ≥6. While both clinical severity thresholds had 100% sensitivity, VAN was more specific (90% vs 74% for NIHSS ≥6). Similarly, while VAN and NIHSS ≥6 had 100% negative predictive value, VAN had a 74% positive predictive value while NIHSS ≥6 had only a 58% positive predictive value. Conclusions The VAN screening tool accurately identified ELVO patients and outperformed a NIHSS ≥6 severity threshold and may best allow clinical teams to expedite care and mobilize resources for ELVO patients. A larger study to both validate this screening tool and compare with others is warranted.
Trends in two year risk of repeat revascularisation or death from cardiovascular disease after coronary artery bypass grafting or percutaneous coronary intervention in Western Australia, 1980–2001

Aims: To investigate whether, over the 21 year period 1980–2001, there had been a reduction in the risk of repeat revascularisation or death from cardiovascular disease in the cohort of all patients who were treated by coronary revascularisation in Western Australia. Setting: State of Western Australia. Patients: All patients treated by coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) between 1980 and 2001. Design: Cohort study. Main outcome measures: Risk of repeat coronary artery revascularisation procedures (CARP) and risk of death from cardiovascular disease after first CARP. Results: After a CABG procedure, the two year risk of repeat revascularisation remained low (less than 2%) across the period 1980–2001. For PCI, however, this risk declined significantly from 33.6% in 1985–9 to 12.4% in 2000–1. The risk of death from cardiovascular disease after a CARP declined by about 50% between 1985 and 2001. Conclusions: Outcomes such as the risk of repeat revascularisation and the risk of death from cardiovascular disease have improved significantly for patients who underwent CARPs across the period 1980–2001. This has occurred despite an increasing trend in first CARP rates among older people and those with a recent history of myocardial infarction.
A Pilot Study of the Use of Oral Ivermectin to Treat Head Lice in Primary School Students in Australia

Abstract: Head lice are a common, costly public health problem worldwide. We aimed to determine the feasibility of an ivermectin intervention program. Consenting students in two schools were screened for head lice. Infested students and siblings at one school were offered a head lice fact sheet and two doses of oral ivermectin, 7 days apart. Parents of infested students in the other school were given the same fact sheet and asked to treat the child and siblings using their preferred topical treatment. Seven hundred two of 754 (93.1%) students enrolled in the two schools were screened; 40 (5.3%; 95% CI 3.7–6.9) had head lice; 31 (9.4%; 95% CI 6.1–12.2) in the intervention school and nine (2.5%; 95% CI 1.1–3.8) in the control school. Subsequently 93.6% of children in the intervention school were treated with oral ivermectin. No adverse events were reported. At 6 months the reduction in the head lice infestation rates for the intervention and control schools were 87% and 56%, respectively. This pilot study suggests that school wide screening for head lice and the administration of oral ivermectin is feasible and acceptable. A randomized controlled trial at 20 schools is planned.

On the Capacity of a CSMA-Based Multi-Hop Linear Network with Poisson Distributed Nodes

In this paper we consider a multi-hop ad hoc network where nodes are distributed according to a Poisson point process (PPP) over a line. A slotted Carrier Sense Multiple Access protocol is used to transmit data from a source to a destination node, through multiple relays. Due to the hidden terminal node problem interferences are present and reduce the network capacity. Performance is evaluated in terms of mean ergodic capacity of the generic link. Results show that there exists an optimum value of nodes' density maximizing the performance and this value changes when varying the source-destination distance.
Matrix Completion from Noisy Entries

Given a matrix M of low-rank, we consider the problem of reconstructing it from noisy observations of a small, random subset of its entries. The problem arises in a variety of applications, from collaborative filtering (the 'Netflix problem') to structure-from-motion and positioning. We study a low complexity algorithm introduced in [1], based on a combination of spectral techniques and manifold optimization, that we call here OPTSPACE. We prove performance guarantees that are order-optimal in a number of circumstances.
Six3 inactivation causes progressive caudalization and aberrant patterning of the mammalian diencephalon

The homeobox gene Six3 represses Wnt1 transcription. It is also required in the anterior neural plate for the development of the mammalian rostral forebrain. We have now determined that at the 15- to 17-somite stage, the prospective diencephalon is the most-anterior structure in the Six3-null brain, and Wnt1 expression is anteriorly expanded. Consequently, the brain caudalizes, and at the 22- to 24-somite stage, the prospective thalamic territory is the most-anterior structure. At around E11.0, the pretectum replaces this structure. Analysis of Six3;Wnt1 double-null mice revealed that Six3-mediated repression of Wnt1 is necessary for the formation of the rostral diencephalon and that Six3 activity is required for the formation of the telencephalon. These results provide insight into the mechanisms that establish anteroposterior identity in the developing mammalian brain.
Pneumatic servo-controlled material testing device capable of operating at high temperature water and irradiation conditions: Dissertation

Special requirements set for the constructional materials used in energy production have strongly influenced the challenges in the component design work. Many material parameters such as corrosion, fracture mechanics, fatigue and oxide films are needed as input data for such work. The generation of reliable data calls also for more sophisticated testing systems. The newly developed pneumatic loading technology (patented in Finland and international patents pending) provides important potential benefits and has already been successfully applied to testing many kinds of materials in different test environments. As the moving parts that penetrate the pressure boundary are not needed, the friction force at the sealing element location is avoided. Therefore the load control with pneumatic loading unit is more accurate than with the conventional servo-hydraulic devices. This enables testing of small size samples which is an advantage e.g. when testing irradiated materials or testing materials inside the reactor core of a nuclear power plant and especially in determining environmentally assisted crack growth rates of structural materials. Furthermore, the new design enables simultaneous testing of several samples, which helps produce more reliable statistical data in a more economical way. This thesis summarizes my work done at the Technical Research Centre of Finland over the past 9 years to increase the knowledge of factors affecting material testing devices and material properties in gas and aqueous coolants at high temperatures. The developed pneumatic servo-controlled material testing device has been used to perform crack growth rate tests as a function of stress intensity factor K for AISI 316 stainless steel and Inconel 182 weld metal in Boiling Water Reactor (BWR) coolant by using small size (10x10x55 mm) three point bending specimens. The load and displacement were controlled during these tests by the pneumatic servo-controlled fracture measuring device (PSCFM device) and based on test results crack growth rates for Inconel weld metal and AISI 316 have been calculated. During the tests, accuracy with very slow
Chlorambucil Encapsulation into PLGA Nanoparticles and Cytotoxic Effects in Breast Cancer Cell

The present work aimed to develop and evaluate a colloidal system composed of poly (DL-lactide-co-glycolide) (PLGA) nanoparticles (NPs) associated with chlorambucil (CHB) and its effects on cancer cells. The nanoparticles showed %EE (>92%), a mean particle size in the range of 240 to 334 nm and zeta potential of -16.7 to -26.0 mV. In vitro release profile showed a biphasic pattern, with an initial burst for all formulations. The scanning electron microscopy of CHB-nanoparticles showed regular spherical shapes, smooth surface without aggregations. Differential scanning calorimetry thermograms, UV-vis absorption, fluorescence emission and Fourier transform infrared spectroscopy were performed showing the entrapment of the antitumoral in drug delivery system. CHB encapsulated in PLGA nanoparticles decrease the survival rates of the breast cancer cells: 68.9% reduction of cell viability on MCF-7 cell line and 59.7% on NIH3T3. Our results indicated that polymeric nanoparticles produced by classical methods are efficient drug delivery systems for CHB.
Verification of Evolving Graph-structured Data under Expressive Path Constraints

Integrity constraints play a central role in databases and, among other applications, are fundamental for preserving data integrity when databases evolve as a result of operations manipulating the data. In this context, an important task is that of static verification, which consists in deciding whether a given set of constraints is preserved after the execution of a given sequence of operations, for every possible database satisfying the initial constraints. In this paper, we consider constraints over graph-structured data formulated in an expressive Description Logic (DL) that allows for regular expressions over binary relations and their inverses, generalizing many of the well-known path constraint languages proposed for semi-structured data in the last two decades. In this setting, we study the problem of static verification, for operations expressed in a simple yet flexible language built from additions and deletions of complex DL expressions. We establish undecidability of the general setting, and identify suitable restricted fragments for which we obtain tight complexity results, building on techniques developed in our previous work for simpler DLs. As a by-product, we obtain new (un)decidability results for the implication problem of path constraints, and improve previous upper bounds on the complexity of the problem.
Motivic invariants of arc-symmetric sets and blow-Nash equivalence

We define invariants of the blow-Nash equivalence of Nash function germs, in a similar way to the motivic zeta functions of Denef and Loeser. As a key ingredient, we extend the virtual Betti numbers, which were known for real algebraic sets, to a generalized Euler characteristic for projective constructible arc-symmetric sets. Actually we prove more: the virtual Betti numbers are not only algebraic invariants, but also Nash invariants of arc-symmetric sets. Our zeta functions enable one to distinguish the blow-Nash equivalence classes of Brieskorn polynomials of two variables. We prove moreover that there are no moduli for the blow-Nash equivalence in the case of an algebraic family with isolated singularities.
Magnetic resonance imaging findings of true bifid mandibular condyle with duplicated mandibular fossa

Bifid mandibular condyle (BMC) is a rare asymptomatic morphological alteration with no predilection for age group or gender. Its morphology varies from a shallow groove to two condylar heads with separate necks, oriented mediolaterally or anteroposteriorly. This report describes an unusual case of anteroposterior bifid condyle in a 39‐year‐old female patient with the main complaint of mouth‐opening limitation and a deviation of the mandible to the left side. Magnetic resonance imaging (MRI) findings revealed a bifid condyle on the left side and duplicated mandibular fossa, with the articular disc over the anterior head. The MRI images in the open‐mouth position revealed minimal movement of the condyle. Despite the increased number of mediolateral bifid mandibular condyle cases described in the literature, none of previously reported cases of BMC included an anteroposterior bifid condyle case with two distinct mandibular fossa.

Sources of the diet-heart controversy: confusion over population versus individual correlations.

AN IMPORTANT SOURCE of current misunderstanding and controversy about diet-disease relationships is the inappropriate extrapolation of evidence from group data to the individual and vice versa. In this editorial piece the difference is illustrated between correlations of risk factors and disease found in individuals and those found between populations. An attempt is made to clarify the causal inference possible when these correlations are concordant and discordant. An analytic approach is encouraged in which both sources of information are considered, i.e., relationships among individuals and between populations, as well as their consistency with other data, before arriving at inference about the meaning of diet-heart, diet-cancer, or, for that matter, any statistical association. It is further suggested here that factors that determine the average and usual population levels of risk characteristics are likely to be the major determinants of mass disease. These influences on population risk may be the same as, or different from, those factors that predominantly influence risk factor level and the risk factor-disease relationship among individuals. We demonstrate that the causes of individual and population correlations are mathematically and conceptually independent. From an understanding of these ideas, the fallacy may be avoided of rejecting important causal influences in populations when relationships appear weak or absent in an individual patientas well as the inappropriate application of group data to the individual, which is called " the ecological fallacy.

Collective Intelligence for Smarter API Recommendations in Python

Software developers use Application Programming Interfaces (APIs) of libraries and frameworks extensively while writing programs. In this context, the recommendations provided in code completion pop-ups help developers choose the desired methods. The candidate lists recommended by these tools, however, tend to be large, ordered alphabetically and sometimes even incomplete. A fair amount of work has been done recently to improve the relevance of these code completion results, especially for statically typed languages like Java. However, these proposed techniques rely on the static type of the object and are therefore inapplicable for a dynamically typed language like Python. In this paper, we present PyReco, an intelligent code completion system for Python which uses the mined API usages from open source repositories to order the results based on relevance rather than the conventional alphabetic order. To recommend suggestions that are relevant for a working context, a nearest neighbor classifier is used to identify the best matching usage among all the extracted usage patterns. To evaluate the effectiveness of our system, the code completion queries are automatically extracted from projects and tested quantitatively using a ten-fold cross validation technique. The evaluation shows that our approach outperforms the alphabetically ordered API recommendation systems in recommending APIs for standard, as well as, third-party libraries.
The Neural Basis of Recollection Rejection: Increases in Hippocampal–Prefrontal Connectivity in the Absence of a Shared Recall-to-Reject and Target Recollection Network

Recollection rejection or “recall-to-reject” is a mechanism that has been posited to help maintain accurate memory by preventing the occurrence of false memories. Recollection rejection occurs when the presentation of a new item during recognition triggers recall of an associated target, a mismatch in features between the new and old items is registered, and the lure is correctly rejected. Critically, this characterization of recollection rejection involves a recall signal that is conceptually similar to recollection as elicited by a target. However, previous neuroimaging studies have not evaluated the extent to which recollection rejection and target recollection rely on a common neural signal but have instead focused on recollection rejection as a postretrieval monitoring process. This study utilized a false memory paradigm in conjunction with an adapted remember–know–new response paradigm that separated “new” responses based on recollection rejection from those that were based on a lack of familiarity with the item. This procedure allowed for parallel recollection rejection and target recollection contrasts to be computed. Results revealed that, contrary to predictions from theoretical and behavioral literature, there was virtually no evidence of a common retrieval mechanism supporting recollection rejection and target recollection. Instead of the typical target recollection network, recollection rejection recruited a network of lateral prefrontal and bilateral parietal regions that is consistent with the retrieval monitoring network identified in previous neuroimaging studies of recollection rejection. However, a functional connectivity analysis revealed a component of the frontoparietal rejection network that showed increased coupling with the right hippocampus during recollection rejection responses. As such, we demonstrate a possible link between PFC monitoring network and basic retrieval mechanisms within the hippocampus that was not revealed with univariate analyses alone.
