Advocating for students with learning and behavior challenges: Insights from teachers who are also parents

Abstract Parents and educators are expected under IDEIA to work together on educational decision-making for students with disabilities. While collegial relationships in this process are intended, partnerships are not always formed because both parties can struggle to understand each other’s perspective. Parents may hold their view, while educators may have another. What happens when parents are also educators? Can stronger partnerships be forged when parent-educators exist in both roles? This paper presents the cases of three parent-educators and their struggles in advocating for their own children with disabilities. From those experiences we provide parents and educators lessons to carry forward as well as resources for improving parent–school relationships in special education.
The Relationship between Role Conflict and Burnout among Secondary School Counselors in Sarawak

Purpose: Despite the relatively high degree of research on counselors in schools, there remain lack of research on the relationship between role conflict and burnout among secondary school counselors. School counselors are by far the increasing sub-group in the school community, yet little is known about the counselors’ well-being in schools. Three aspects of burnout, i.e. emotional exhaustion, depersonalization and personal accomplishment were measured in this study and their relationship with the role conflict was explored. Design/methodology/approach: Statistical analyses using Structural Equation Modelling (SEM) revealed that there was a significant positive relationship between Role Conflict and Emotional Exhaustion and also between Role Conflict and Depersonalization. Findings: Nevertheless, there was no significant relationship between Role Conflict and Personal Accomplishment. Qualitative survey also indicated that role conflict influenced burnout among secondary school counselors in Sarawak. The results of the three dimensions of burnout revealed that emotional exhaustion and depersonalization were at high level where as personal accomplishment was at low level, therefore the secondary school counselors in Sarawak are at the risk of burnout. Research limitations: The data of this research were based on goverment secondary school counselors throughout the state of Sarawak, therefore, the generalizability is confined to government secondary school counselors in the state of Sarawak, Malaysia. Practical implications: This research provides empirical data for the Ministry of Education, school administrators and curriculum experts toward Sarawak secondary school counselors who are at the risk of burnout. This study could have further implications on the prevention of burnout among secondary school counselors and on the design of educational interventions in secondary school counselors development programs that support and strengthen the development of school counselors self efficacy. It is recommended that additional research should be conducted to confirm the effect of counselor-to-student ratio on school counselor burnout. Global Business and Management Research: An International Journal Vol. 10, No. 2 (2018, Special Issue) 11 Originality/value: The use of Structural Equation Modeling to test role conflict and burnout among secondary school counselors in Sarawak provided a venue for testing the relationships in the hypothesized model simultaneously and more accurately.
Discussion Paper Series Intertemporal Distortions in the Second Best Stefania Albanesi

We consider a very general class of public nance problems that encompasses Ramsey models of optimal taxation as well as economies with limited commitment, private information, and political economy frictions. We identify a su¢ cient condition to rule out permanent intertemporal distortions at the optimum: If there exists an admissible allocation that converges to the rst best steady state, then all intertemporal distortions are temporary in the second best. We analyze a series of applications to illustrate the signi cance of this result. We would like to thank Boragan Aruoba, Marco Bassetto, Martin Bodenstein, Sanjay Chugh, Pierre Yared, and seminar participants at the University of Maryland, Georgetown, FRB New York, the FRB Philadelphia, SED 2007, Ente Einaudi, Universidad Carlos III, and the NBER Summer Institute for helpful comments and suggestions.

MobySpace: Mobility Pattern Space Routing for DTNs

Problem: • Routing is a challenge in DTNs (Delay Tolerant Networks). Regular ad- hoc routing protocols fail because the topology suffers from connectivity disruptions. Proposition: • We propose to use mobility patterns of nodes, i.e. regularities in nodes contacts or movements, to define their position in a virtual Euclidean space used for routing. This space is called the MobySpace. • Each node’s position in the MobySpace (its MobyPoint) is flooded throughout the network. Other nodes use this information for routing. • To route a bundle, a node chooses among its physical neighbors. It passes the bundle to the neighbor whose MobyPoint is closest to the destination’s. • The MobySpace can be defined in many ways, e.g. type/number of dimensions, distance function. This poster describes preliminary work.
Multivariate goodness-of-fit tests based on kernel density estimators

The paper is devoted to multivariate goodness-of-fit ests based on kernel density estimators. Both simple and composite null hypotheses are investigated. The test statistic is considered in the form of maximum of the normalized deviation of the estimate from its expected value. The produced comparative Monte Carlo power study shows that the proposed test is a powerful competitor to the existing classical criteria for testing goodness of fit against a specific type of an alternative hypothesis. An analytical way to establish the asymptotic distribution of the test statistic is discussed, using the approximation results for the probabilities of high excursions of differentiable Gaussian random fields.
Paxos-Based Memory Data Replication in Stock Trading System

Primary-backup replication based on shared storage is a classical approach to ensuring high availability and data durability of stock trading systems, but it is difficult to further reduce the system latency due to persistence bottleneck. To solve this problem, a memory data replication approach based on Paxos algorithm is proposed, which accomplishes primary-backup replication through messaging, ensures the strong consistency of data replicas and tolerates possible benign failures. Experiment results have shown that this approach, compared with the shared storage approach, manages to greatly reduce the order processing latency of trading systems and achieve hot failover correctly in the case of server failure.
SER Performance Analysis for Jointing Network Coding and Space Time Codes in DF Relay System

In this paper, a new joint coding scheme that combine the network coding and the conditional distributed space-time codes was proposed in decode-and-forward (DF) wireless relay network. Symbol-error-rate (SER) performance of proposed scheme was analyzed. Based on studying the SER of the traditional distributed space time in three relays system, the SER closed-form and upper-bounds expression of scheme were derived. In our systems, three relays were considered. Two relays were operated as the space time codes, and one relay was used as the simple network coding. The theoretical analysis proved that proposed joint coding scheme had better performance of SER than traditional space time codes in DF relay system. The numerical results shown that our scheme had the lower SER compared with traditional distributed space time codes.

Eduro is a modular mid-size mobile robotic platform designed as both a teaching tool for higher education and a research platform for academia and industry. In this paper we describe the technology used within the Eduro (indoor) and Eduro Maxi HD (outdoor) product lines. Both platforms are designed around a tricycle base with two differentially driven wheels and one caster wheel. The on-board electronics consists of smart sensors and actuators connected by a CAN bus. The main controller module is implemented as a single board x86based computer running Linux OS. This platform participated in several competitions including Eurobot, RobotChallenge and Robotour.
Assessment of voluntary rhythmic muscle contraction-induced exercising blood flow variability measured by Doppler ultrasound

Given recent technological developments, ultrasound Doppler can provide valuable measurements of blood velocity/flow in the conduit artery with high temporal resolution. In human-applied science such as exercise physiology, hemodynamic measurements in the conduit artery is commonly performed by blood flow feeding the exercising muscle, as the increase in oxygen uptake (calculated as a product of arterial blood flow to the exercising limb and the arterio-venous oxygen difference) is directly proportional to the work performed. The increased oxygen demand with physical activity is met through a central mechanism, an increase in cardiac output and blood pressure, as well as a peripheral mechanism, an increase in vascular conductance and oxygen extraction (a major part of the whole exercising muscles) from the blood. The increase in exercising muscle blood flow in relation to the target workload (quantitative response) may be one indicator in circulatory adjustment for the ac- tivity of muscle metabolism. Therefore, the determination of local blood flow dynamics (potential oxygen supply) feeding repeated (rhythmic) muscle contractions can contribute to the understanding of the factors limiting work capacity including, for instance, muscle metabolism, substance utilization and magnitude of vasodilatation in the exercising muscle. Using non-invasive measures of pulsed Doppler ultrasound, the validity of blood velocity/flow in the forearm or lower limb conduit artery feeding to the muscle has been previously demonstrated during rhythmic muscle exercise. For the evaluation of exercising blood flow, not only muscle contraction induced internal physiological variability, or fluctuations in the magnitude of blood velocity due to spontaneous muscle contraction and relaxation induced changes in force curve intensity, superimposed in cardiac beat-by-beat, but also the alterations in the blood velocity (external variability) due to a temporary sudden change in the achieved workload, compared to the target workload, should be considered. Furthermore, a small amount of inconsistency in the voluntary muscle contraction force at each kick seems to be unavoidable, and may influence exercising muscle blood flow, although subjects attempt to perform precisely similar repeated voluntary muscle contractions at target workload (muscle contraction force). This review presents the methodological considerations for the variability of exercising blood velocity/flow in the limb conduit artery during dynamic leg exercise assessed by pulsed Doppler ultrasound in relation to data previously reported in original research.
ESet: Placing Data Towards Efficient Recovery for Large-Scale Erasure-Coded Storage Systems

Erasure coding has been extensively deployed in distributed storage systems to ensure high reliability and low storage overhead. However, erasure coding requires much more disk I/O to recover a damaged data block than replication does, resulting in very long data recovery time. Data placement algorithm can be tailored to speed up data recovery process by exploiting I/O parallelism. However, existing algorithms that obtain good I/O parallelism for replication can not directly work with erasure-coded storage systems; and other algorithms for both replication based and erasure-coded storage systems overlook the importance of recovery I/O parallelism, which may jeopardize the service quality and reliability of these systems. In this paper, we present a data placement strategy named ESet which brings recovery efficiency for each host in a distributed storage system. We define a configurable parameter named overlapping factor for system administrator to easily achieve desirable recovery I/O parallelism. Our simulation results show that ESet can significantly improve the data recovery performance without violating the reliability requirement by distributing data and code blocks across different failure domains.
Multi-modal Orientation Cues in Homing Pigeons1

Abstract How homing pigeons displaced into unfamiliar territory find their way home has been the subject of extensive experimentation and debate. One reason for the controversy is that pigeons seem to use multiple cues. Clock-shifting experiments show that experienced pigeons use the sun as a preferred compass; when it is not available they rely on magnetic cues. That pigeons can home successfully while wearing frosted lenses suggests that landmarks, while not an essential navigational cue, are important in the final stages. The sensory basis of the “map” or position finding system is probably equally or even more complicated. When conditions around the loft are suitable, pigeons may use olfactory cues to find their way or might use some feature of the earth's magnetic field for their navigation. The Wiltschkos (1989) showed that pigeons raised without free access to ambient odors are not disoriented when anosmic while their siblings raised with free access to the prevailing wind were disoriented. Similarly, sibling pigeons from two lofts in Lincoln, Massachusetts. were well oriented or totally disoriented when released at magnetic anomalies under sunny skies depending upon which of the two lofts they had been reared in. All of these experiments and many more suggest that pigeons use multiple and redundant cues to find their way home. Further, there is the suggestion that which cues they adopt may well be influenced by the characteristics of the area around the home loft in which they were reared.

A statistical framework for estimating output-specific efficiencies

This paper presents a statistical framework for estimating output-specific efficiencies for the 2-output case based upon a DEA frontier estimate. The key to the approach is the concept of target output-mix. Being usually unobserved, target output-mixes of firms are modelled as missing data. Using this concept the relevant data generating process can be formulated. The resulting likelihood function is analytically intractable, so a data augmented Bayesian approach is proposed for estimation purposes. This technique is adapted to the present purpose. Some implementation issues are discussed leading to an empirical Bayes setup with data informed priors. A prove of scale invariance is provided. (author's abstract)
Digital Video Multicasting System with Seamless Handover Mechanism

Digital television (TV) has officially entered the handheld application areas since the infrastructure of communications have improved. Most PDAs are equipped with built-in wireless local area network (WLAN). It thus become promising to provide multimedia services to mobile devices if multimedia streams can be transmitted to handheld mobile devices such as PDAs via low-cost WLAN architecture. The goal of this work is to propose seamless handover architecture to support multi-channel and non- interrupted broadcasting of TV programs in an environment with WLAN and handheld devices. Due to the characteristics of WLAN, our proposed architecture is most suitable to be used in the indoor environment.
Visual Tracking Using Multimodal Particle Filter

Visual tracking of humans or objects in motion is a challenging problem when observed data undergo appearance changes (e.g., due to illumination variations, occlusion, cluttered background, etc.). Moreover, tracking systems are usually initialized with predefined target templates, or trained beforehand using known datasets. Hence, they are not always efficient to detect and track objects whose appearance changes over time. In this paper, we propose a multimodal framework based on particle filtering for visual tracking of objects under challenging conditions (e.g., tracking various human body parts from multiple views). Particularly, the authors integrate various cues such as color, motion and depth in a global formulation. The Earth Mover distance is used to compare color models in a global fashion, and constraints on motion flow features prevent common drifting effects due to error propagation. In addition, the model features an online mechanism that adaptively updates a subspace of multimodal templates to cope with appearance changes. Furthermore, the proposed model is integrated in a practical detection and tracking process, and multiple instances can run in real-time. Experimental results are obtained on challenging real-world videos with poorly textured models and arbitrary non-linear motions.
A practical experience concerning the parallel semantic annotation of a large-scale data collection

From a computational point of view, the semantic annotation of large-scale data collections is an extremely expensive task. One possible way of dealing with this drawback is to distribute the execution of the annotation algorithm in several computing environments. In this paper, we show how the problem of semantically annotating a large-scale collection of learning objects has been conducted. The terms related to each learning object have been processed. The output was an RDF graph computed from the DBpedia database. According to an initial study, the use of a sequential implementation of the annotation algorithm would require more than 1600 CPU-years to deal with the whole set of learning objects (about 15 millions). For this reason, a framework able to integrate a set of heterogeneous computing infrastructures has been used to execute a new parallel version of the algorithm. As a result, the problem was solved in 178 days.
PROBING THE STRUCTURE OF QUANTUM MECHANICS

We believe that in the decades to come quantum theory will play an increasingly important role for many different fields. One of the reasons is that technology aims at manipulating and controlling information and energy in ever smaller regions of space and windows of time. As a consequence the behavior of the entities to manipulate and control will become more and more quantum. This means not only spectacular advances of new techniques and outlooks on revolutionary applications, but also a constant stress and attention on the theory of quantum mechanics itself. It is well known that quantum mechanics has been scrutinized in all kind of ways during the past decades, but that still a lot of conceptual problems remain. The problems of standard quantum mechanics are however not only of a conceptual nature. Also the formal mathematical structure of quantum mechanics has been investigated with the aim to make the theory more operational and to found the basic concepts in direct correspondence with what happens in the laboratory. Such an operationally founded quantum mechanics may soon become of great value because of the technological

THE PROTECTIVE ACTION OF A SPECIFIC ENZYME AGAINST TYPE III PNEUMOCOCCUS INFECTION IN MICE

The bacterial enzyme which decomposes the purified capsular polysaccharide of Type III Pneumococcus in vitro also destroys the capsules of the living organisms growing in media and in the animal body. Potent preparations of this same enzyme protect mice against infection with virulent Type III Pneumococcus. The protective action is type-specific. The protective activity of the specific enzyme is destroyed by heat (70°C. for 10 minutes). The enzyme remains in an effective concentration 24 to 48 hours after its injection into normal mice. The enzyme has been found to exert a favorable influence on the outcome of an infection already established at the time of treatment. A definite relationship has been found to exist between the activity of the enzyme in vitro and its protective power in the animal body. The mechanism of the protective action is discussed with special reference to the relation between the decapsulation of the bacteria by the enzyme and the phagocytic response of the host.

Emballage, logistique et économie circulaire : prémices d'un nouveau packaging scorecard

– Dans les systemes de production comme de commercialisation et de consommation actuels, l'emballage est omnipresent. Ses fonctions sont multiples. Elles concernent autant la qualite des produits qu'il contient, leur mise en valeur par ses aspects marketing, que la logistique via les activites de manutention, de stockage et de transport qu'il permet. Partenaire indispensable des differents acteurs (fournisseurs, industriels, prestataires de services logistiques, transporteurs, grossistes, detaillants, consommateurs) au sein des chaines logistiques, il a donne lieu, depuis les annees 2000, a l'elaboration de packaging scorecards. Cependant, face au changement de paradigme qu'amene la transition amorcee vers une economie circulaire, qu'en est-il de la pertinence de ces tableaux de bord adaptes a une conception lineaire des chaines logistiques ? Apres avoir etudie la relation en devenir entre l'emballage, la logistique et l'economie circulaire, cet article remet en cause la pertinence des principaux packaging scorecards existants et pose les bases d'un nouveau packaging scorecard deliberement oriente vers les principes de l'economie circulaire.
