Holography: A survey

The development of holography and the state of the art in recording and displaying information, microscopy, motion, pictures, and television applications are discussed. In addition to optical holography, information is presented on microwave, acoustic, ultrasonic, and seismic holography. Other subjects include data processing, data storage, pattern recognition, and computer-generated holography. Diagrams of holographic installations are provided. Photographs of typical holographic applications are used to support the theoretical aspects

Teaching behavior modification to expectent parents

Numerous studies have demonstrated the efficacy of teaching parents behavior modification in order to manage and prevent child-related problems. The present study investigated a preventive parent training program using a multiple baseline design by teaching expectant parents behavior modification principles and applications. Three expectant mothers received individualized home training and hands-on training at a nursery school. Each expectant mother also received videotaped feedback on instructions and differential attention and praise she provided to a pre-selected child-participant while at the nursery school. After training began, the expectant mothers increased their us~ of praise to the child\u27s cooperative behavior and their use of statements of a contingency and two behavior reduction procedures when the child was behaving oppositionally, The results indicate that expectant parents can successfully be taught effective child management skills before they have their children

Generation 1.5 Students’ Academic Success: The Interrelationship Between Capital Used and Identity Formation

As the number of people immigrating to the United States increases, so does the number of generation 1.5 students in K-12 education (Kanno & Cromley, 2013). With more generation 1.5 students graduating from U.S. high schools, more are also matriculating into higher education institutions (Harklau & Siegal, 2009; Kanno & Cromley, 2013; Kanno & Harklau, 2012; Roberge, 2009). While some generation 1.5 students are successful in U.S. higher education, others are not, and the percentage of generation 1.5 students who are successful is disproportionately less than the percentage of those students who have a U.S. heritage culture (Kanno & Harklau, 2012). Many studies have occurred regarding generation 1.5 students’ writing discourse. Other inquiries have compared the capital that exists in education versus the capital generation 1.5 students possess. Researchers have also investigated how generation 1.5 students’ identity impacts their academic success. This inquiry complements prior research by using a basic qualitative research paradigm to explore not only what capitals generation 1.5 students employ and how they use these capitals but also how generation 1.5 students’ identity interrelates to their use of capital for academic success. This study found that generation 1.5 students utilized family social capital, peer social capital, navigational capital, linguistic capital, motivational capital, and aspirational capital to be academically successful, and these capitals interrelated to generation 1.5 students’ identity, including their personal, heritage, social, student, linguistic, and writer identities. Additionally, this inquiry includes implications for how educators and administrators can support generation 1.5 students to be academically successful

Magnetic shielding and exotic spin-dependent interactions

Experiments searching for exotic spin-dependent interactions typically employ magnetic shielding between the source of the exotic field and the interrogated spins. We explore the question of what effect magnetic shielding has on detectable signals induced by exotic fields. Our general conclusion is that for common experimental geometries and conditions, magnetic shields should not significantly reduce sensitivity to exotic spin-dependent interactions, especially when the technique of comagnetometry is used. However, exotic fields that couple to electron spin can induce magnetic fields in the interior of shields made of a soft ferro- or ferrimagnetic material. This induced magnetic field must be taken into account in the interpretation of experiments searching for new spin-dependent interactions and raises the possibility of using a flux concentrator inside magnetic shields to amplify exotic spin-dependent signals.Comment: 8 pages, 5 figure

Characterization of 1.55-μm pulses from a self-seeded gain-switched Fabry-Pérot laser diode using frequency-resolved optical gating

The intensity and frequency chirp of picosecond pulses from a self-seeded gain-switched Fabry-Perot laser diode have been directly measured using the technique of frequency-resolved optical gating. Measurements over an output sidemode suppression ratio (SMSR) range of 15-35 dB show that higher SMSR's are associated with an increasingly linear frequency chirp across the output pulses. This complete pulse characterization allows the conditions for optimum pulse compression to be determined accurately, and indicates that transform-limited, pedestal free pulses can be obtained at an SMSR of 35 dB

The Value of Caregiver Time: Costs of Support and Care for Individuals Living with Autism Spectrum Disorder

WHY IS THIS AN IMPORTANT ISSUE?An estimated 1 in 86 children are diagnosed with Autism Spectrum Disorder (ASD)1 making it the most commonly diagnosed childhood neurological condition in Canada.2 The true costs of lifelong support for people living with ASD3 are often underestimated and fail to acknowledge the value of caregiver time over the lifespan. Significant gaps in publically provided support systems leave the cost burden to be picked up by families. Relying on continued family supports where community services are fragmented or unavailable is not a sustainable approach. WHAT DOES THE RESEARCH TELL US? A continuum of supports are needed Most people living with ASD need supports that range from occasional assistance with higher level tasks, like organizing appointments or banking, to those who need continuous help with daily living.4 Areas where supportive care may be needed can be categorized broadly to include: self care, home living, service co-ordination, personal organization, health and safety management, adult day opportunities/employment, transportation, advocacy and social skills. These supports are most successful when they address the individual’s uniqueness in terms of communication, social, sensory, behavioural needs and physical and/or mental health conditions. Currently there are a lack of available supports, limiting opportunities for socialization, employment and residential living resulting in reduced independence for adults with ASD

Laying the Foundation for Policy: Measuring Local Prevalence for Autism Spectrum Disorder

WHY IS THIS AN IMPORTANT ISSUE?Autism Spectrum Disorder (ASD)1 is the most common neurological condition diagnosed in children in Canada. Estimates of prevalence are reported as national numbers but may not reflect local numbers and consequently local needs. Local and provincial ASD prevalence estimates can be used by policy makers to inform local service delivery, resource allocation and future planning.WHAT DOES THE RESEARCH TELL US?ASD prevalence is on the rise Estimates of ASD prevalence in Canada have risen dramatically over the past several decades.2 The reason for the dramatic rise is uncertain and may be a result of a combination of a true rise in incidence, changing diagnostic criteria and increased awareness.3 It has been speculated that Alberta may have higher numbers of persons with ASD due to family in-migration to utilize higher levels of funding for ASD supports compared to other provinces.4 Prior to this study, there were no prevalence estimates for Alberta to assess this theory. A better understanding of Alberta ASD prevalence is critical as these estimates assist policy-makers, clinicians and educators in planning for school supports, adult day programs, employment programs, housing options and other programs essential to enhancing quality of life for individuals living with ASD and their families
