An Unmanned Aerial Vehicle-Based Imaging System for 3D Measurement of Unpaved Road Surface Distresses

Road condition data are important in transportation management systems. Over the last decades, significant progress has been made and new approaches have been proposed for efficient collection of pavement condition data. However, the assessment of unpaved road conditions has been rarely addressed in transportation research. Unpaved roads constitute approximately 40% of the U.S. road network, and are the lifeline in rural areas. Thus, it is important for timely identification and rectification of deformation on such roads. This article introduces an innovative Unmanned Aerial Vehicle (UAV)-based digital imaging system focusing on efficient collection of surface condition data over rural roads. In contrast to other approaches, aerial assessment is proposed by exploring aerial imagery acquired from an unpiloted platform to derive a threedimensional (3D) surface model over a road distress area for distress measurement. The system consists of a lowcost model helicopter equipped with a digital camera, a Global Positioning System (GPS) receiver and an Inertial Navigation System (INS), and a geomagnetic sensor. A set of image processing algorithms has been developed for precise orientation of the acquired images, and generation of 3D road surface models and orthoimages, which allows for accurate measurement of the size and the dimension of the road surface distresses. The developed system has been tested over several test sites ∗To whom correspondence should be addressed. E-mail: chunsunz@ unimelb.edu.au. with roads of various surface distresses. The experiments show that the system is capable for providing 3D information of surface distresses for road condition assessment. Experiment results demonstrate that the system is very promising and provides high accuracy and reliable results. Evaluation of the system using 2D and 3D models with known dimensions shows that subcentimeter measurement accuracy is readily achieved. The comparison of the derived 3D information with the onsite manual measurements of the road distresses reveals differences of 0.50 cm, demonstrating the potential of the presented system for future practice.
Electrokinetic remediation and microbial community shift of β-cyclodextrin-dissolved petroleum hydrocarbon-contaminated soil

Electrokinetic (EK) migration of β-cyclodextrin (β-CD), which is inclusive of total petroleum hydrocarbon (TPH), is an economically beneficial and environmentally friendly remediation process for oil-contaminated soils. Remediation studies of oil-contaminated soils generally prepared samples using particular TPHs. This study investigates the removal of TPHs from, and electromigration of microbial cells in field samples via EK remediation. Both TPH content and soil respiration declined after the EK remediation process. The strains in the original soil sample included Bacillus sp., Sporosarcina sp., Beta proteobacterium, Streptomyces sp., Pontibacter sp., Azorhizobium sp., Taxeobacter sp., and Williamsia sp. Electromigration of microbial cells reduced the biodiversity of the microbial community in soil following EK remediation. At 200 V m−1 for 10 days, 36% TPH was removed, with a small population of microbial cells flushed out, demonstrating that EK remediation is effective for the present oil-contaminated soils collected in field.
The link between prosody and language skills in children with specific language impairment (SLI) and/or dyslexia.

BACKGROUND
Children with specific language impairment (SLI) and dyslexia are known to have impairments in various aspects of phonology, which have been claimed to cause their language and literacy impairments. However, 'phonology' encompasses a wide range of skills, and little is known about whether these phonological impairments extend to prosody.


AIMS
To investigate certain prosodic abilities of children with SLI and/or dyslexia, to determine whether such children have prosodic impairments, whether they have the same pattern of impairments, and whether prosodic impairments are related to language and literacy deficits.


METHODS & PROCEDURES
Six subtests of the Profiling Elements of Prosodic Systems - Child version (PEPS-C) were used to investigate discrimination/comprehension and imitation/production of prosodic forms that were either independent of language or that had one of two linguistic functions: chunking (prosodic boundaries) and focus (contrastive stress). The performance of three groups of 10-14-year-old children with SLI plus dyslexia, SLI, and dyslexia were compared with an age-matched control group and two younger control groups matched for various aspects of language and reading.


OUTCOMES & RESULTS
The majority of children with SLI and/or dyslexia performed well on the tasks that tested auditory discrimination and imitation of prosodic forms. However, their ability to use prosody to disambiguate certain linguistic structures was impaired relative to age-matched controls, although these differences disappeared in comparison with language-matched controls. No, or only very weak, links were found between prosody and language and literacy skills in children with SLI and/or dyslexia.


CONCLUSIONS & IMPLICATIONS
Children with SLI and/or dyslexia aged 10-14 years show an impaired ability to disambiguate linguistic structures for which prosody is required. However, they are able on the whole to discriminate and imitate the actual prosodic structures themselves, without reference to linguistic meaning. While the interaction between prosody and other components of language such as syntax and pragmatics is problematic for children with SLI and/or dyslexia, prosody itself does not appear to be a core impairment.
ActivPass: Your Daily Activity is Your Password

This paper explores the feasibility of automatically extracting passwords from a user's daily activity logs, such as her Facebook activity, phone activity etc. As an example, a smartphone might ask the user: "Today morning from whom did you receive an SMS?" In this paper, we observe that infrequent activities (i.e., outliers) can be memorable and unpredictable. Building on this observation, we have developed an end to end system ActivPass and experimented with 70 users. With activity logs from Facebook, browsing history, call logs, and SMSs, the system achieves 95% success (authenticates legitimate users) and is compromised in 5.5% cases (authenticates impostors). While this level of security is obviously inadequate for serious authentication systems, certain practices such as password sharing can immediately be thwarted from the dynamic nature of passwords. With security improvements in the future, activity-based authentication could fill in for the inadequacies in today's password-based systems.
An evaluation of the multidisciplinary approach to psychiatric diagnosis in elderly people.

OBJECTIVE
To determine the accuracy of psychiatric diagnoses made by two community psychogeriatric teams operating a multidisciplinary assessment procedure.


DESIGN
Comparison of team diagnosis with independent formal assessment and consensus diagnosis by research psychiatrists.


SETTING
Two community psychogeriatric teams with similar operational policies in an inner London health district.


SUBJECTS
100 people aged 65-90 (70 women) newly referred to the teams.


MAIN OUTCOME MEASURES
Concordance between team and research diagnoses.


RESULTS
Agreement between team and research diagnoses ranged from 90% to 99% for the specific psychiatric disorders studied. There was no significant difference between medical and non-medical team members in their diagnostic performance compared with the research psychiatrists. Increased diagnostic accuracy by team members was associated with longer experience of team working, regardless of the team members' professional background.


CONCLUSIONS
The multidisciplinary approach to the assessment of referrals to these community teams for the elderly is not associated with misdiagnosis of psychiatric disorder.
Rabies Situation in Cambodia

BACKGROUND
Rabies, a fatal but preventable zoonosis, is a major public health problem in developing countries. In Cambodia the disease burden is largely underestimated because patients with encephalitis following dog bites are rarely hospitalized and die at home. Since 1998 Institut Pasteur in Cambodia (IPC), Phnom Penh has been the only source of free post-exposure prophylaxis (PEP) and post-mortem diagnosis.


METHODS
The 1998-2007 data compiled by IPC was analyzed to describe all treated patients for PEP, results of human testing and confirmed rabies cases, and results of animal testing. From dog bites' characteristics, we defined a suspected rabid dog bite injury (SRDBI) in humans as a bite that was unprovoked, from a dog that died spontaneously, or from a dog that was reported sick. We applied a deterministic probability model to estimate 2007 rabies human mortality nationwide from the estimated incidence of rabid dog bites, the body distribution of bite wounds, and the probability of PEP access.


RESULTS
During 1998-2007, 124,749 patients received PEP at IPC (average 12,470; range 8,907-14,475), and 63 fatal human cases presenting with encephalitis following a dog bite were reported, in which 73% were confirmed positive for rabies by direct immunofluorescence assay or by reverse-transcriptase polymerase chain reaction. During 1998-2007, IPC tested 1,255 animal brain samples; 1,214 (97%) were from dogs including 610 (49%) positive samples. In 2007, 14,475 patients received PEP (100 PEP/100,000 people in Cambodia) including 95% who resided in Phnom Penh (615 PEP/100,000) or five neighboring provinces. The predictive model estimated 810 human rabies deaths would occur in 2007 (95%confidence interval [CI] 394-1,607), an incidence of 5.8/100,000 (95% CI 2.8-11.5).


CONCLUSIONS
Access to PEP is only sufficient for Phnom Penh residents. In 2007, the estimated rabies related mortality exceeded that of malaria and that of dengue. A national rabies control program is needed to improve surveillance and access to PEP, and to initiate vaccination campaigns in dogs.
A Stationary Reference Frame Grid Synchronization System for Three-Phase Grid-Connected Power Converters Under Adverse Grid Conditions

Grid synchronization algorithms are of great importance in the control of grid-connected power converters, as fast and accurate detection of the grid voltage parameters is crucial in order to implement stable control strategies under generic grid conditions. This paper presents a new grid synchronization method for three-phase three-wire networks, namely dual second-order generalized integrator (SOGI) frequency-locked loop. The method is based on two adaptive filters, implemented by using a SOGI on the stationary αβ reference frame, and it is able to perform an excellent estimation of the instantaneous symmetrical components of the grid voltage under unbalanced and distorted grid conditions. This paper analyzes the performance of the proposed synchronization method including different design issues. Moreover, the behavior of the method for synchronizing with highly unbalanced grid is proven by means of simulation and experimental results, demonstrating its excellent performance.
The Ambiguous Intentions Hostility Questionnaire (AIHQ): a new measure for evaluating hostile social-cognitive biases in paranoia.

INTRODUCTION
This study reports on the development of a new measure of hostile social-cognitive biases for use in paranoia research, the Ambiguous Intentions Hostility Questionnaire (AIHQ). The AIHQ is comprised of a variety of negative situations that differ in terms of intentionality. Items were developed to reflect causes that were ambiguous, intentional, and accidental in nature.


METHODS
Participants were 322 college students who completed the AIHQ along with measures of paranoia, hostility, attributional style, and psychosis proneness. The reliability and validity of the AIHQ was evaluated using both correlational and multiple regression methods.


RESULTS
The AIHQ had good levels of reliability (internal consistency and interrater reliability). The AIHQ was positively correlated with paranoia and hostility and was not correlated with measures of psychosis proneness, which supported the convergent and discriminant validity of the scale. In addition, the AIHQ predicted incremental variance in paranoia scores as compared to the attributional, hostility, and psychosis proneness measures. Ambiguous items showed the most consistent relationships with paranoia.


CONCLUSIONS
The AIHQ appears to be a reliable and valid measure of hostile social cognitive biases in paranoia. Recommendations for using the AIHQ in the study of paranoia are discussed.
Automatic Generation of Constructable Brick Sculptures

Fabrication of LEGO R © models in large scale requires careful pre-planning to produce constructable and stable models. We propose a system that, starting with a voxelization of a 3D mesh, merges voxels to form larger bricks, and then analyzes and repairs structural problems, finally outputting a set of building instructions. We also present extensions such as producing hollow models, fulfilling limits on the number of bricks of each size, and including colors. Results (both real and virtual) and timings show significant improvements over previous work.
Diabetes mellitus, fasting glucose, and risk of cause-specific death.

BACKGROUND
The extent to which diabetes mellitus or hyperglycemia is related to risk of death from cancer or other nonvascular conditions is uncertain.


METHODS
We calculated hazard ratios for cause-specific death, according to baseline diabetes status or fasting glucose level, from individual-participant data on 123,205 deaths among 820,900 people in 97 prospective studies.


RESULTS
After adjustment for age, sex, smoking status, and body-mass index, hazard ratios among persons with diabetes as compared with persons without diabetes were as follows: 1.80 (95% confidence interval [CI], 1.71 to 1.90) for death from any cause, 1.25 (95% CI, 1.19 to 1.31) for death from cancer, 2.32 (95% CI, 2.11 to 2.56) for death from vascular causes, and 1.73 (95% CI, 1.62 to 1.85) for death from other causes. Diabetes (vs. no diabetes) was moderately associated with death from cancers of the liver, pancreas, ovary, colorectum, lung, bladder, and breast. Aside from cancer and vascular disease, diabetes (vs. no diabetes) was also associated with death from renal disease, liver disease, pneumonia and other infectious diseases, mental disorders, nonhepatic digestive diseases, external causes, intentional self-harm, nervous-system disorders, and chronic obstructive pulmonary disease. Hazard ratios were appreciably reduced after further adjustment for glycemia measures, but not after adjustment for systolic blood pressure, lipid levels, inflammation or renal markers. Fasting glucose levels exceeding 100 mg per deciliter (5.6 mmol per liter), but not levels of 70 to 100 mg per deciliter (3.9 to 5.6 mmol per liter), were associated with death. A 50-year-old with diabetes died, on average, 6 years earlier than a counterpart without diabetes, with about 40% of the difference in survival attributable to excess nonvascular deaths.


CONCLUSIONS
In addition to vascular disease, diabetes is associated with substantial premature death from several cancers, infectious diseases, external causes, intentional self-harm, and degenerative disorders, independent of several major risk factors. (Funded by the British Heart Foundation and others.).
Validating an innovative real-time Delphi approach-A methodological comparison between real-time and conventional Delphi studies

Article history: Received 29 October 2010 Received in revised form 28 March 2011 Accepted 6 April 2011 Available online 28 May 2011 A novel and innovative real-time Delphi technique is introduced in order to address previously identified weaknesses of the conventional Delphi method, such as complicated facilitator tasks, lack of real-time presentation of results, and difficulties in tracking progress over time. We demonstrate how the real-time (computer-based) method increases the efficiency of the process, accommodates expert availability, and reduces drop-out-rates. Modifications in the Delphi procedure (e.g. change of iteration principle) not only increase efficiency but also change the nature and process of the survey technique itself. By identifying and analysing three individual effects (initial condition effect, feedback effect, and iteration effect) we examine whether the modifications in the survey process cause deviations to the survey results. Empirical data obtained from both conventional as well as real-time Delphi studies is analysed based onmultiple statistical analyses. The research findings indicate that significant differences between the two Delphi survey formats do not exist and final survey results are not affected by changes in the survey procedure. © 2011 Elsevier Inc.

Severe Wound of the Head by a Bear

SEVERE W0U2TD OF THE HEAD BY A BEAR. Reported by V. Richards, Esq., Civil Surgeon of Bancaorah. Bolai Dey, a Ilindoo, aged 22 years, was admitted into the Bancoorah Charitable Dispensary, on the 30th of December, 1870. The elder brother, who accompanied the patient, stated that while they were cutting wood in the jungle, a bear rushed out and attacked Bolai, inflicting severe wounds. He (the elder brother) struck the bear with an axe so vigorously, that it turned upon him, but, owing to the density of the jungle, he was able to make his escape. Bolai in the meantime retreated, and ran and walked one mile towards home.
Self-training on refined clause patterns for relation extraction

Within the context of Information Extraction (IE), relation extraction is oriented towards identifying a variety of relation phrases and their arguments in arbitrary sentences. In this paper, we present a clause-based framework for information extraction in textual documents. Our framework focuses on two important challenges in information extraction: 1) Open Information Extraction and (OIE), and 2) Relation Extraction (RE). In the plethora of research that focus on the use of syntactic and dependency parsing for the purposes of detecting relations, there has been increasing evidence of incoherent and uninformative extractions. The extracted relations may even be erroneous at times and fail to provide a meaningful interpretation. In our work, we use the English clause structure and clause types in an effort to generate propositions that can be deemed as extractable relations. Moreover, we propose refinements to the grammatical structure of syntactic and dependency parsing that help reduce the number of incoherent and uninformative extractions from clauses. In our experiments both in the open information extraction and relation extraction domains, we carefully evaluate our system on various benchmark datasets and compare the performance of our work against existing state-of-the-art information extraction systems. Our work shows improved performance compared to the state-of-the-art techniques. © 2017 Elsevier Ltd. All rights reserved.
PERFORMANCE AND DECISION MAKING

■ Abstract Theory and research on small group performance and decision making is reviewed. Recent trends in group performance research have found that process gains as well as losses are possible, and both are frequently explained by situational and procedural contexts that differentially affect motivation and resource coordination. Research has continued on classic topics (e.g., brainstorming, group goal setting, stress, and group performance) and relatively new areas (e.g., collective induction). Group decision making research has focused on preference combination for continuous response distributions and group information processing. New approaches (e.g., group-level signal detection) and traditional topics (e.g., groupthink) are discussed. New directions, such as nonlinear dynamic systems, evolutionary adaptation, and technological advances, should keep small group research vigorous well into the future.
Service oriented architecture maturity models: A systematic literature review

Introduction: In recent years, the maturity model research has gained wide acceptance in the area of information systems and many Service Oriented Architecture (SOA) maturity models have been proposed. However, there are limited empirical studies on in-depth analysis and validation of SOA Maturity Models (SOAMMs). Objectives: The objective is to present a comprehensive comparison of existing SOAMMs to identify the areas of improvement and the research opportunities. Methods: A systematic literature review is conducted to explore the SOA adoption maturity studies. Results: A total of 20 unique SOAMMs are identified and analyzed in detail. A comparison framework is defined based on SOAMM design and usage support. The results provide guidance for SOA practitioners who are involved in selection, design, and implementation of SOAMMs. Conclusion: Although all SOAMMs propose a measurement framework, only a few SOAMMs provide guidance for selecting and prioritizing improvement measures. The current state of research shows that a gap exists in both prescriptive and descriptive purpose of SOAMM usage and it indicates the need for further research.
The UNC-CH MCH Leadership Training Consortium: Building the Capacity to Develop Interdisciplinary MCH Leaders

This article describes the UNC-CH MCH Leadership Consortium, a collaboration among five MCHB-funded training programs, and delineates the evolution of the leadership curriculum developed by the Consortium to cultivate interdisciplinary MCH leaders. In response to a suggestion by the MCHB, five MCHB-funded training programs—nutrition, pediatric dentistry, social work, LEND, and public health—created a consortium with four goals shared by these diverse MCH disciplines: (1) train MCH professionals for field leadership; (2) address the special health and social needs of women, infants, children and adolescents, with emphasis on a public health population-based approach; (3) foster interdisciplinary practice; and (4) assure competencies, such as family-centered and culturally competent practice, needed to serve effectively the MCH population. The consortium meets monthly. Its primary task to date has been to create a leadership curriculum for 20–30 master’s, doctoral, and post-doctoral trainees to understand how to leverage personal leadership styles to make groups more effective, develop conflict/facilitation skills, and identify and enhance family-centered and culturally competent organizations. What began as an effort merely to understand shared interests around leadership development has evolved into an elaborate curriculum to address many MCH leadership competencies. The collaboration has also stimulated creative interdisciplinary research and practice opportunities for MCH trainees and faculty. MCHB-funded training programs should make a commitment to collaborate around developing leadership competencies that are shared across disciplines in order to enhance interdisciplinary leadership.
Effect of electrode material on AC electrical conductivity of organic zinc phthalocyanine semiconducting thin films

Abstract The AC electrical conductivity of thermally evaporated zinc phthalocyanine, ZnPc, semiconducting thin films was measured in the temperature range of 180–430 K and frequency between 0.1 and 20 kHz. Gold and aluminum contact electrodes were employed and both showed ohmic contacts. In both cases, the conductivity showed strong dependence on both temperature and frequency. Such dependence is related to the relevant temperature and frequency range under consideration. However, for both electrode materials, the AC conductivity σ ( ω ) is found to vary with angular frequency, ω , as ω s , with the index s  ≤ 1 suggesting a dominant hopping conduction process at low temperatures ( σ decreased with temperature above 330 K, while for samples with Au-electrodes it decreased with temperature above 430 K. The former decrease in σ was attributed to oxygen exhaustion, while the latter was ascribed to α–β-phase transition.
