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

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

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

Characterization of high-dimensional entangled systems via mutually unbiased measurements

Mutually unbiased bases (MUBs) play a key role in many protocols in quantum science, such as quantum key distribution. However, defining MUBs for arbitrary high-dimensional systems is theoretically difficult, and measurements in such bases can be hard to implement. We show experimentally that efficient quantum state reconstruction of a high-dimensional multi-partite quantum system can be performed by considering only the MUBs of the individual parts. The state spaces of the individual subsystems are always smaller than the state space of the composite system. Thus, the benefit of this method is that MUBs need to be defined for the small Hilbert spaces of the subsystems rather than for the large space of the overall system. This becomes especially relevant where the definition or measurement of MUBs for the overall system is challenging. We illustrate this approach by implementing measurements for a high-dimensional system consisting of two photons entangled in the orbital angular momentum (OAM) degree of freedom, and we reconstruct the state of this system for dimensions of the individual photons from d=2 to 5.Comment: 8 page

Phase-coherent repetition rate multiplication of a mode-locked laser from 40 MHz to 1 GHz by injection locking

We have used injection locking to multiply the repetition rate of a passively mode-locked femtosecond fiber laser from 40 MHz to 1 GHz while preserving optical phase coherence between the master laser and the slave output. The system is implemented almost completely in fiber and incorporates gain and passive saturable absorption. The slave repetition rate is set to a rational harmonic of the master repetition rate, inducing pulse formation at the least common multiple of the master and slave repetition rates
