Elementary Classroom Teachers Attitudes and Perspectives of Elementary Physical Education.

Physical educators have long proclaimed that physical education class is an important academic discipline to a students’ education. With learning objectives taking place in the affective, cognitive and psychomotor domains. Yet, physical education has been marginalized in today’s society. One way to gain support of physical education is getting support from other educators. The literature suggests that teacher’s need to promote their programs to gain support and lose the marginality tag that has been place on physical education. For this study the researchers surveyed elementary classroom teachers (n=219). The survey consisted of seven questions, and of the five questions the classroom teachers were asked to further explain their responses to the survey question. The purpose of this study was to obtain and better understand elementary classroom teacher’s attitudes and perspectives regarding elementary physical education. Generally, elementary classroom teachers attitudes were positive towards elementary physical education.
UN ESTUDIO COMPARATIVO SOBRE VALORES ÉTICOS EN ESTUDIANTES UNIVERSITARIOS A comparative study on ethical values in university students

Considering the importance and viability that a program on ethical values and professional ethics be incorporated to the university curriculum, a descriptive transactional and comparative study between two groups of university students was carried out in order to verify the presence and values expressed in a variable, that is, the ethical values that students have in relation with their personal and professional life. The results point out to the necessity of fostering said values; particularly, the values related to knowledge acquisition.
The Mismeasure of Women

The subtitle of this elegant book, Why women are not the better sex, the inferior sex, or the opposite sex, instantly conveys its major themes and main message. While Carol Tavris would like to eschew all "oversimplified" dichotomies, including the maximalist/minimalist differences controversy (p. 288) that divides the feminist community, she takes the firm position that the psychosocial political context is the most powerful, albeit not the only, explanation for the behavior of both women and men. It is the context of oppression, poverty, and multiple frustrations, rather than female hormones, she suggests, that explains the higher rates of depression among women--although she even questions the actuality of such differences, given men's own different style of expressing despair. It is power imbalance, rather than women's "natural" speaking styles, that creates the popular "two-cultures theory of miscommunication" (p. 297). She insists that differences between moral reasoning, the need for love and attachement, the need for achievement, capacity for empathy or pacifist leanings are trivial at best, while the true differences lie in the division of labor at home and in the workplace, in the different ways that universal emotions are allowed to be expressed by each gender, and in the different gendered life stories that our culture offers women and men for making meaning out of their life experiences.The second organizing thread of The Mismeasure of Women is Tavris's ever-present voice, arguing her positions carefully and convincingly, leaning on a large body of empirical research, and taking clear and open sides on every issue. The author addresses many of the myths that have shaped the post-Freudian psychology of women, and comes down equally hard on myths of denigration as on myths of glorification, confronting them without asperity, yet with forthrightness and courage, at the risk of stepping on many feminist political toes. Tavris is concerned that cultural feminists' and other feminist movements' emphasis on differences even when they entail female superiority, ends up with a focus on human nature rather than on sociopolitical power arrangements. Concerned with the admittedly thorny issue of the sexual survivor syndrome that has been taken up with such enthusiasm by many powerless women caught in bad relationships Tavris asks: "How does a woman come to focus exclusively on past sexual abuse as the major reason for her unhappiness, when many other current factors are often involved as well" (p. 316) and she wonders about the wisdom and usefulness, for women, of adopting victim identities. …
Cardinal Symptoms of Mania in Clinically Referred Preschoolers: Description of Three Clinical Cases with Presumptive Preschool Bipolar Disorder

Despite a growing body of empirical data describing the discriminant and longitudinal validity of mania in older children, little research has been conducted investigating the presence of mania symptoms in preschool-aged children. This report describes three cases of preschool children (ages 3.6 to 5.2) who presented to a subspecialty mental health clinic manifesting age-adjusted mania-like symptoms. Developmental manifestations of DSM-IV mania symptoms described include grandiosity, hypersexuality, elation, racing thoughts, and decreased need for sleep. These symptoms have been shown to be highly specific to distinguish bipolar disorder from attention deficit hyperactivity disorder (ADHD) in older children. Possible manifestations of mood cycling are also described. Clinical observations, parental reports, and related family mental health history are reviewed.
Postpartum depression and melancholic type of personality: a pilot study

Objectives This is a pilot study on the relationship between a personality structure called “melancholic type” (typus melancholicus, TM) and postpartum depression. We tested the following hypotheses: 1) the main features of TM (orderliness, conscientiousness, hyper/heteronomia and intolerance of ambiguity) portray the personality structure of a group of mothers prone to a kind of postpartum depression whose clinical features are characterized by psychomotor retardation, depression and guilt feelings/ ideas (“melancholia” sensu Tellenbach); 2) the features of the puerperal crisis taking place during the early phases of motherhood in these women bears deep analogies with the kind of existential pathogenic situation (“pre-melancholic situation” sensu Tellenbach) characterized by “includence”, “remanence” and “despair” which (according to phenomenological literature) leads to “melancholic” depression.
EXPERIMENTAL AND THEORETICAL STUDIES OF ORDERED ARRAYS OF MICRODROPLETS LEVITATING OVER LIQUID AND SOLID SURFACES

Levitating droplets of liquid condensate are known to organize themselves into ordered arrays over hot liquid-gas interfaces. The mechanism of levitation is the Stokes drag force acting on a drop from the flow originated at the interface. We report experimental observation of levitation and self-organization of liquid microdroplets (with a size on the order of 10 μm) over both hot liquid-gas interfaces and heated dry solid surfaces. In the experiment a copper block heated from below is used as the substrate. Degassed ultrapure water is used as the working liquid. An optical recording is made using a high-speed camera equipped with a microscope objective of high resolving power. Working liquid is deposited with a syringe onto the substrate to form a horizontal liquid layer. The heater is then switched on, resulting in evaporation and formation of ordered droplet array levitating over a liquid surface. With a short pulse of an air jet a dry spot is formed on the copper surface. When the array moves to the dry spot, the droplets continue to levitate over the solid dry surface. Even though the lifetime of the array is shorter over the dry surface, its geometric characteristics are similar. Mathematical models are developed that explain droplet levitation for both configurations and lead to new power laws for the levitation height as a function of droplet size. The predictions of the models are in good agreement with the experimental data.
Synthesis and Antimicrobial Activity of Fe:TiO2 Particles

TiO2 and iron-doped TiO2 were synthesized by sol-gel method. TiO2 and 0.5 %mol Fe:TiO2 were calcined at 500 and 800 °C for 3 h. The synthesized particles were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), UV-VIS diffuse reflectance spectrophotometry (UV/DRS), scanning electron microscopy (SEM) and scanning electron microscope-energy dispersive X-Ray analysis (SEM-EDX). The XRD patterns of all samples that were calcined at 500 °C showed only anatase phase. On increasing temperature from 500 to 800 °C, the anatase phase transformed to rutile phase. For 0.5 %mol Fe:TiO2, pseudobrookite (Fe2TiO5) phase was observed at 800 °C. The particles that contained rutile showed higher antibacterial activities against E.coli, B. subtilis, and S. aureus than anatase phase, under fluorescent irradiation.
A fall detection system using low resolution infrared array sensor

Nowadays, aging society is a big problem and demand for monitoring systems is becoming higher. Under this circumstance, a fall is a main factor of accidents at home. From this point of view, we need to detect falls expeditiously and correctly. However, usual methods like using a video camera or a wearable device have some issues in privacy and convenience. In this paper, we propose a system of fall detection using a low resolution infrared array sensor. The proposed system uses this sensor with advantages of privacy protection (low resolution), low cost (cheap sensor), and convenience (small device). We propose four features and based on them, classify activities as either a fall or a non-fall using k-nearest neighbor (k-NN) algorithm. We show a proof-of-concept of our proposed system using a commercial-off-the-shelf (COTS) hardware. Results of experiments show the detection rate of higher than 94% irrespective of training data contains object's data or not.
Electron Collisions with Atoms and Molecules

Measurements of the production of atomic and molecular metastable states are performed using a novel frozen solid layer detector. This includes examination of solid CO2 and N2O layers in metastable detection, measurements of N( 2P) production from dissociation of N2, investigations into the suitability of solid neon layers for detection of S( 1D) based on electron-impact dissociation studies of OCS and production of O(1S) and CO(a3Π) in electron-impact dissociation of methanol. Novel solid layers for detection of metastable states were examined to determine which products they were sensitive to. First, CO2 layers were deposited and were found to be sensitive to both O(1S) and N2(a Πg) metastable states. The relative efficiency of these layers as a function of temperature and lifetime of the state formed from the impinging O(1S) atoms are reported. Mechanisms which may be responsible for the radiation through formation of CO3 or its ion are also suggested. The detection of metastable N2(a Πg) states from solid N2O layers is also reported. A study of N(2P) production after electron-impact dissociation of N2 was also performed. It was determined that two excitation channels contribute to production of this state. Time-of-flight and fragment kinetic energy spectra are presented for 100 eV impact energy. Excitation function data is also provided over the 0 eV to 200 eV range for one of these channels. Dissociation processes are proposed for both production channels which appear to be due to both a direct dissociation and pre-dissociation mechanism. Intermediary states are proposed for both channels. Investigations into the suitability of solid neon layers for the detection of S(1D) are performed through studies of electron-impact dissociation of OCS. It was found that while production of S(1D) is likely occurring, interactions with solid neon layers do not result in emission within the optical spectral range of our photo-multiplier tube. However, an ultraviolet emission from these layers was detected in these experiments. While the nature of this feature was not definitively identified, some possible processes which may be responsible are discussed. Future investigations to determine the source of the emission are proposed. In addition, likely production channels of S(1D) are suggested. Electron-impact dissociation of methanol was also performed. It was observed that both CO(a3Π) and O(1S) metastable states are produced and detected with solid xenon layers. While production of CO(a3Π) has been reported previously, this appears to be the
A Comparative Study on High-Voltage Spacer-Damper Performance and Assessment: Theory, Experiments and Analysis

This paper reports on the experimental analysis of commercially available spacer-dampers used to suppress wind induced Aeolian vibrations on transmission lines with bundle conductors. Three spacer-dampers with different bushing-shaft designs, overall mass, and fabrication technology have been selected for this evaluation. Spacer-damper performances have been examined in a temperature- controlled testing facility by measuring their frequency and force-displacement response, in order to determine whether the bushing-shafting design meets the prerequisite to withstand the undesirable motions of the coupled sub-conductors. The tests showed that the hysteresis force-displacement test gives a better indication of an efficient spacer-damper and its energy absorption but is not consistent enough to describe the entire list of needed features against wind induced vibrations, i.e., its mobility or impedance, admittance and receptance vs. frequency. However, to investigate the working range of the spacer-damper in terms of the relative amplitudes between the frame and the arm of the spacer-damper, an analytical and experimental sensitivity model was developed. Analytically, the sensitivity models are based on the partial differential of an explicit dynamic model of the arm-rubber-frame and arm-rubber while the transfer functions have been experimentally established from the identification technique of force response frequency. In both approaches, the same conclusion was observed, although, analytically some assumptions have been made. In addition, a sensitivity analysis of the energy absorbed with variation of the ambient temperature was conducted during the hysteresis test.

Detection of OpticDisk based on Saliency Map

Correspondence: zfan@stu.edu. cn 1 Key Laboratory of Digital Signal and Image Processing of Guangdong Province, School of Engineering, Shantou University, Guangdong, China. Full list of author information is available at the end of the article †Equal contributor Abstract Detecting the optic disk (OD) is very important for the fundus image analysis. In this paper, we propose an algorithm which allows us to automatically segment the optic disk from a fundus image. The method proposed for the extraction of the optic disk contour is mainly based on the saliency map, which can make the OD more prominent in the fundus image. After the saliency map of the fundus image is obtained, threshold processing is performed on the saliency map to obtain the region which includes the optic disk center. Then we search the fittest center in the region and approximate the optic disk contour by a circle. The implemented algorithm has been validated on the public dataset Digital Retinal Images for Optic Nerve Segmentation (DRIONS). The average values obtained (an accuracy of 100%, area over lap of 0.7933, true positive and false positive fraction of 0.8909 and 0.1350, mean absolute distance of 6.1031) demonstrate that the method is feasible and effective for automatic segmentation of the optic disk.
The Role And Remediation Of Attention Deficits In Performance Of Mathematics Facts By Children With ADHD

Attention-Deficit/Hyperactivity Disorder (ADHD) is a disorder characterized by the occurrence of behavior patterns that display abnormal levels of attention, impulsivity and hyperactivity. Parents and teachers commonly associate attention deficits with underachievement in children with ADHD. The purposes of this study were (a) to provide an assessment method to investigate attention in children with ADHD, (b) to evaluate the impact of an observing response to focus attention on relevant stimuli on the accuracy and rate of responding to mathematics facts, and (c) to examine the role of delay aversion on responding. Participants were repeatedly exposed to four conditions. During Observing conditions, discriminative responding to a relevant (Relevant Observing) or irrelevant (Irrelevant Observing) stimulus was required before solution of the mathematics problem. During control conditions, responses to the mathematics facts could occur immediately after problem presentation (No Wait) or after a short delay (Wait). The results indicate, first, that rates of correct responding on mathematics facts increased for all participants across sessions in all conditions. Second, the observing response requirement to enhance control by the relevant stimulus did not produce consistent differences in rate and accuracy when compared to the other conditions. Finally, Wait and No Wait conditions did not produce consistent differences in responding for children with or without ADHD, suggesting that delay aversion did not ii affect performance. Likely explanations for these results are discussed along with implications for the design of future interventions for children with ADHD.
Inequalities creating economic barriers to owning mobile phones in India

In India, men own around 70% of mobile phones, creating a gender digital divide for the most widely owned information and communication technology (ICT) in the world. This study investigates the factors responsible for the inability of 245 female slum-dwellers in India earning less than $2 a day to own a mobile phone. Open, axial and selective coding of survey responses shows that socio-cultural, economic, demographic, psychological, communication-related, and health related inequalities in the lives of the respondents create eight economic barriers precluding respondents from owning some of the least expensive mobile phones worth $15 or so on installments of $1 a month.
Influence of Graphene Sheet on Microstructure and Properties of Ni-based Alloy Coatings Prepared by Laser Cladding

Ni-based alloy cladding layers with different graphene sheet additions were prepared by laser cladding on the 40CrNi2Si2MoV steel substrate. The influence of the graphene sheet on the microstructure and properties of the cladding layers was investigated. The results show that owing to the diffusion-reaction dissolution, the graphene sheet addition does not bring a corresponding change in the phase constitutions of the cladding layers, i. e. , the cladding layers are still composed of γ-Ni, Ni3B, and M7C3 phases. But what has changed is that the solidified structure is refined, and the volume fractions of the eutectic and the carbide are increased with the increase of graphene sheet addition. As a result, the hardness and the wear resistance of the cladding layers gradually increase, whereas the friction coefficient firstly decreases and then increases, with the lowest friction coefficient obtained at 0.5 vol.% graphene sheet addition. Compared to the Ni-based alloy cladding layers with micro-size graphite additions, the studied cladding layers exhibit improved hardness and wear resistance, good forming quality, and increased friction coefficient.

Ant-Inspired Approach for Resource Localization in Mobile Ad-Hoc Networks

Computer networks are constantly emerging, and in today’s world, we see new needs and new kinds of networks addressing these needs. Situations such as emergency and rescue operations present a demand for mobile ad-hoc networks, a kind of networks with fundamentally different characteristics than traditional wired networks. Scarce resources and possibly low connectivity call for new techniques and approaches to traditional problems. Where possible, resource localization tools will probably be included in the applications needing it, enabling them to tune the search to the applications needs and characteristics. However, such needs are not always possible to predict a priori, and we then need a system enabling nodes to autonomously localize needed resources that are not present in the node itself. In this thesis, we propose a general-purpose resource localization solution for mobile ad-hoc networks. Nodes in mobile ad-hoc networks should function autonomously with as little outside intervention as possible, preserving the self-* properties. Such systems are common in nature, and may be used as inspiration when designing computer systems. In this thesis, we look at how stigmergy — the foraging behavior of ants — may be used to localize resources in a mobile adhoc network. When walking between their nest and a food source, ants leave pheromone trails on the ground, and by probabilistically choosing branches with the most pheromone, they are able to find the shortest path between their nest and the food. This behavior has inspired a lot of solutions to optimization problems like routing. We have designed and implemented a system exploiting what we call opposite stigmergy, where artificial ants are released from a resource-requesting node and at each intermediate node probabilistically choose the least recently used neighbor as next hop. This makes ants search every nook and cranny of the network, as opposed to regular ant-inspired algorithms, where ants are concentrated on one or a few most optimal paths. Our preliminary performance tests show that our ant-inspired approach has, if tuned correctly, the potential to outperform the much simpler floodingbased solution in certain scenarios. The ant solution has shown to be able to localize resources with less sent and received messages if more than one node requests the same (or similar) resources. For scenarios where nodes have a high number of neighbors, however, we see that the ant approach requires a lot of time and resources to localize a resource. We also suggest a few potential fixes that may be able to lower both the response time as well as the resource consumption, enabling the ant solution to perform even better.
