A Qualitative Inquiry into the Contextualized Parental Mediation Practices of Young Children’s Digital Media Use at Home

Technologies are increasingly adopted and used by young children at home. Parents play an important role in shaping their media use, keeping certain possibilities open for children to play, learn, and socialize while limiting others. Nevertheless, the literature on parental mediation of young children’s media use is scant. In this article, we describe a qualitative, mixed-method study involving 24 parents and 36 children aged 3 to 9, and focus on the contextual factors that shape (transitions between) parental mediation practices. The results point to the emergence of new manifestations of parental mediation and provide evidence of their dynamic, often paradoxical nature. In particular, the insights on distant mediation, various buddy styles, and participatory learning, as well as the value of a wholeness approach for understanding children’s conditions for media engagement, suggest new prospects for parental mediation literature.
Towards a Systemic Theory of Gifted Education-1-Towards a Systemic Theory of Gifted Education

In this target article, we argue that current approaches to gifted education are based on the erroneous view that to understand the development of exceptionality we need to understand firstly the components of giftedness, including cognitive such as intelligence and noncognitive factors such as motivation. In contrast, systemic approaches to understanding exceptionality focuses on the interactions of these components where it is important to firstly understand the system that leads to exceptionality before it is possible to understand its components. After analyzing the weaknesses of current approaches to gifted education we then present three central arguments for the need for a paradigm shift. This is followed by an introduction of constructs of a systemic approach of gifted education. Using the actiotope model of giftedness to understand the development of exceptionality, this article describes the basic principles of a gifted education that is based on this systemic approach.

Childcare and fertility in (western) Germany

This paper analyzes the relationship between children’s day care and fertility in Germany. First, different modes of childcare are discussed with regard to their availability and costs. We then estimate the impact of having access to public day care and care in social networks on first birth probabilities of western German women in the 1980s and 1990s. The empirical analysis does not reveal any statistically significant effect of childcare availability on fertility. We conclude that the overall institutional constraints of day care in (western) Germany prevent the compatibility of childrearing and employment, thereby forcing women to choose between a continuous employment career or childlessness.

Evaluation of timing and rEsponsEs to physiothErapEutic trEatmEnt

In several treatment regimens, the recognition of chronobiology contributes to the therapeutic process through the effective use of temporization protocols. The purpose of the present study was to evaluate the relationship between the response to physiotherapeutic treatment and the time of day when such treatment was performed, as well as the chronotype of orthopedic and rheumatologic patients in a clinical physiotherapy school. The population studied was treated in the morning and evening periods. The patients were divided into three groups of pathologies with similar treatments, which were as follows: syndrome of shoulder impact (n=33), knee artrosis (n=17), and lombalgia (n=23). At the end of ten treatment sessions, data concerning pain, percentage of subjective improvement, chronotype, and age were compared. At the end of the study, it was observed that the time of day when treatment was performed influenced the results of individuals treated in the evenings but had no influence on the individuals treated in the morning. In addition, the evening schedule was the most well suited for intermediate individuals.
Reading memory traces in cultured neuronal networks by probabilistic analysis

In this thesis, I am studying the enhancement of the collective burst dynamics, burst activation and propagation in hippocampal neuronal networks in-vitro by using optogenetic techniques. Channelrhodopsin-2 transfected hippocampal neuronal cultures were grown on MEAs for simultaneous optical stimulation and electrical recording from neuronal networks. We found low frequency photo-stimulation protocols that are sufficient to induce potentiation of network bursting, modifying bursting dynamics and increasing interneuronal synchronization. This study shows that mild stimulation protocols that do not enforce particular activity patterns onto the network can be highly effective inducers of network-level plasticity. I also investigated how this network level plasticity can be indicated in the burst activation and propagation dynamics by looking at the leader-follower neuronal relationship. I found that low frequency photo-stimulation is able to modify the temporal relationship between follower and leader neurons. It is shown that, by using fade-in photo-stimulation, there is a significant shortening of intra-burst firing rate peak delay of follower electrodes after offset of the stimulation compared to unperturbed spontaneous activity. This study indicated that network level potentiation is associated with a tighter temporal relationship between leader and follower neurons.
PARENTING STYLES AND OFFSPRING’S POLYSUBSTANCE USE IN BIOLOGICAL AND ADOPTIVE FAMILIES

From the perspective of socialization theory, one aspect of the family environment that has been hypothesized to be one of the strongest predictors of offspring’s substance use is parenting style. This study examined the associations between offspring’s perspectives of fathers’ and mothers’ parenting styles and the polysubstance use (PSU) in biological and adoptive families by youth and young adults. Long-term influences of the parenting styles of fathers and mothers were also investigated by using longitudinal data on offspring’s PSU. Results of structural equation modelling analyses showed that offspring’s time 1 PSU scores were significantly related to both positive and negative parenting styles, whereas overall time 2 PSU scores were more strongly related to offspring’s age and gender than parenting. In both time 1 and time 2 models, different paths were found to be significant for paternal and maternal parenting models. Only adopted offspring PSU scores were found to be significantly influenced by parenting of both fathers and mothers when offspring became older. These findings confirm: (a) the uniqueness and potential vulnerability of adopted offspring in relation to PSU, (b) the difference in influence for fathers’ and mothers’ parenting on offspring’s PSU, and (c) the long-term influences of parenting style on adopted offspring.
THE INTERMEDIATE-LINE REGION IN ACTIVE GALACTIC NUCLEI

We show that the recently observed suppression of the gap between the broad-line region (BLR) and the narrow-line region (NLR) in some active galactic nuclei (AGNs) can be fully explained by an increase of the gas density in the emitting region. Our model predicts the formation of the intermediate-line region (ILR) that is observed in some Seyfert galaxies by the detection of emission lines with intermediate-velocity FWHM ∼ 700–1200 km s−1. These lines are believed to be originating from an ILR located somewhere between the BLR and NLR. As was previously proved, the apparent gap is assumed to be caused by the presence of dust beyond the sublimation radius. Our computations with the use of the cloudy photoionization code show that the differences in the shape of the spectral energy distribution from the central region of AGNs do not diminish the apparent gap in the line emission in those objects. A strong discontinuity in the line emission versus radius exists for all lines at the dust sublimation radius. However, increasing the gas density to ∼ cm−3 at the sublimation radius provides the continuous line emission versus radius and fully explains the recently observed lack of apparent gap in some AGNs. We show that such a high density is consistent with the density of upper layers of an accretion disk atmosphere. Therefore, the upper layers of the disk atmosphere can give rise to the formation of observed emission-line clouds.
Hydrological dispersion module of JRODOS: renewed chain of the emergency response models of radionuclide dispersion through watersheds and rivers

Hydrological Dispersion Module (HDM) of JRODOS includes the chain of the models describing the washing out of the accidental deposition from the watersheds to rivernet and radionuclide transport in rivers and reservoirs. This modelling chain of HDM was renewed by the integration of two models. One-dimensional model RIVTOX_SV provides possibilities for the computing radionuclide transport in the branched river networks. Two-dimensional model for shallow reservoirs and river floodplains COASTOX_UN used algorithms of the parallel computing on the unstructured mesh of the finite volume method. The renewed modelling chain was tested for the sub-watersheds of the Danube river and the Dnieper river.
A Compressive System Matrix Design in Spectral Imaging by a Homogenization Algorithm

Context: Compressive spectral imaging systems (CSI) use a focal plane array (FPA) to measure two-dimensional (2D) coded projections of a three-dimensional (3D) spatiospectral scene. A reconstruction algorithm based on compressive sensing theory exploits the projections to retrieve the underlying 3D scene. Compressive sensing relies on two principles: Sparsity and incoherence. Higher incoherence drives to better-reconstructed image quality. In CSI systems, a random design of the coded apertures elements guarantees a high incoherence between the sensing matrix and the representation basis. However, when a coded aperture is designed completely random, it is possible that some voxels not be sensed at all or they be sensed more than once. Method: This paper presents a random algorithm for a colored coded apertures design by homogenizing defined parameters of the colored coded aperture snapshot spectral imaging system (C-CASSI) representative matrix. Homogenization parameters guarantee that all voxels are sensed at least once. The homogenization is achieved by weighting the selected parameters of the matrix, in this case, the average of unblocking elements per column and the average of unblocking elements per row. Results/Conclusions: Simulations show a higher performance in the PSNR of the reconstructed images by using the proposed approach, as compared to traditional random coded apertures.
Synthesization and Decentralized Identification of Self-Similar Processes

In the first part of this dissertation, we propose a filter-based generator for the synthesization of self-similar traffics. It can produce long range dependent traffics with adjustable levels of bustiness and correlation, and is parsimonious in the number of model parameters. By comparing it with existing self-similar traffic synthesizers, e.g., the RMD and the Paxson IFFT algorithms, the proposed filter-based synthesizer has the advantages that the synthetic traffic can be generated on the fly, and always produces non-negative-valued traffic. The implications between the correlation coefficient (a quantity that only measures the linear dependence) and mutual information (a quantity that can represent the general dependence) is subsequently investigated. The obtained results suggest that for weakly correlated random variables such as two instances of a self-similar process with a long time lag, half the square of the correlation coefficients might be a reasonable approximation to the mutual information. Continuing from the synthesization of processes with heavy tails, we turn to study the impact of such processes on decentralized detection. Several interesting results are found. Firstly, the optimality of identical sensor system for the exponential distribution family has been verified. A side result along this research line is that the optimal performance of the serial two-sensor system is the same as that of the parallel two-sensor system for exponential sources. This is somewhat surprising because it is generally considered that the serial two-sensor system has better performance than the parallel two-sensor system. Secondly, for a more general class of distribution families, we propose several propositions on the optimality of the identical system. A straightforward approach to test the optimality of identical sensor system often results in searching all local -9 minimums in the solution space that is defined through a set of nonlinear equations. However, this approach is not tractable in certain situations. Our propositions then provide an alternative for optimality test of identical sensor system. Besides, they can be applied to other decentralized detection problems like the detection of lifetime encountered in survival analysis and failure time analysis or the determination of the degree of self-similarity of the whole network system based on geographically dispersed measurements of the packet inter-arrival times on different links. Finally, with the help of numerical study on functions and equations, we analytically confirm the optimality of identical sensor system over Gaussian sources.
A review on general introduction to medicinal plants, its phytochemicals and role of heavy metal and inorganic constituents

Plants play an impo r tant role in the development of new d r ugs . Phytochemical s are the natural compound o ccur in plants, vegetables and fruits, that work with nutrients and fibers to act against disease s or more specifically to a ct again st diseases. As the plants are directly in contact with air, water and soil, the constituents of these sources might contaminate the plants. In addition to the toxic elements such as mercury, arsenic, lead, nickel and cadmium which might be present in some plants and threatened the consumer health, especially the children and elderly. Useful elements such as calcium, magnesium, zinc, manganese and iron are also usually present in plants which help the good health. Many countries have already evaluated their popular herbal medicines with regard to toxic heavy metals . ( Naseem Ullah, Muhammad Zahoor, Farhat Ali Khan, Shazeb Khan .

The Informational Content of Initial Public Offerings

The ability of capital markets to distinguish firms of different value by the size of their initial equity offerings is attenuated when insiders can sell equity more than once. A model is developed in which there is price risk from holding equity between periods. When the uncertainty is small. there must be pooling in the first period. When uncertainty is large. the pooling equilibria dominate the separating equilibrium.

MODELING AND CLOSED LOOPCONTROL OF BLDC MOTOR USING ASINGLE CURRENT SENSOR

For closed loop current control of BLDC motor, the motor phase currents are measured using current sensors. These sensors are bulky, heavy and expensive. Also the use of different current sensors can cause undesirable imbalance in phase currents as well as torque fluctuations due to differences in current sensor sensitivities. These drawbacks can be avoided by using a single current sensor placed on the DC link. Here an algorithm is presented to obtain the phase current values from the DC link current. The proposed and conventional systems were simulated using MATLAB/Simulink, to compare their performance.
Re: Relation between sweating and wool yellowing in Merino and Romney sheep

Five adult Merino and five adult Romney ewes with 7 months growth of fleece were subjected to nine different environmental challenges in a climate controlled room on consecutive days where the temperature humidity index (THI) was varied from 74.2 to 91.3 for up to 7 h at each exposure. Secretions were collected from glands in the skin on the back, midside and belly regions of each sheep. The sheep were shorn 5 months later. There was a significantly curvilinear increase in total skin gland output and the rate of secretion of titratable alkalinity and potassium ions with increasing THI. Romney sheep had a higher secretion rate than Merino sheep with no significant site effect. The rate of secretion of titratable alkalinity and potassium ions by the skin glands were both strongly related to tristimulus (Y-Z) of the fleece at shearing (base yellow) (R = 0.93, 0.92) and after incubation of the wool sample at 40°C and 100%RH for 6 d (challenge yellow) (R = 0.96, 0.95). These data indicate a particularly strong relationship between the rate of secretion of titratable alkalinity and potassium ions by the skin glands and the later propensity of the fleece to develop a yellow discolouration.
Innovation Focused Strategy and Earnings Management

This study utilizes three approaches to investigate the extent to which firms with an innovation focused strategy engage in earnings management through the use of income smoothing, real activities, and the use of discretionary accruals. Several results are reported. First, firms with an innovative strategy report a greater percentage of earnings in the fourth quarter indicating greater earnings management. Second, innovative firms use real activities to a greater extent than non-innovative firms to manage earnings when income approaches certain earnings benchmarks. Lastly, innovative strategy firms engage in the use of discretionary accruals to a greater degree than other firms. DOI: 10.15458/85451.36
Designing computer based cognitive tools to assist learners to interpret graphs and tables

This paper reports on the development and evaluation of cognitive tools used to interpret graphs and tables. The development of these tools was informed by research about how learners interpreted graphs and tables. A prototype of the cognitive tools was trialed with a small sample of preservice teachers. This prototype was then improved and used again with a larger sample. Data from individual audit trails of software use, journal entries and interviews with a small sample of preservice teachers were used to evaluate the cognitive tools. The findings showed that the simple, context-specific cognitive tools developed helped to reduce the cognitive load associated with the interpretation of graphs and tables.
Wiener’s test for space-time random walks and its applications

This paper establishes a criterion for whether a d-dimensional random walk on the integer lattice Zd visits a space-time subset infinitely often or not. It is a precise analogue of Wiener's test for regularity of a boundary point with respect to the classical Dirichlet problem. The test obtained is applied to strengthen the harder half of Kolmogorov's test for the random walk.
RhoH Plays Critical Roles in FcεRI-Dependent Signal Transduction in Mast Cells1

RhoH is an atypical small G protein with defective GTPase activity that is specifically expressed in hematopoietic lineage cells. RhoH has been implicated in regulation of several physiological processes including hematopoiesis, integrin activation, and T cell differentiation and activation. In the present study, we investigated the role of RhoH in mast cells by generating RhoH knockout mice. Despite observing normal development of mast cells in vivo, passive systemic anaphylaxis and histamine release were impaired in these mice. We also observed defective degranulation and cytokine production upon FcεRI ligation in RhoH-deficient bone marrow-derived mast cells. Furthermore, FcεRI-dependent activation of Syk and phosphorylation of its downstream targets, including LAT, SLP76, PLCγ1, and PLCγ2 were impaired, however phosphorylation of the γ-subunit of FcεRI remained intact. We also found RhoH-Syk association that was greatly enhanced by active Fyn. Our results indicate that RhoH regulates FcεRI signaling in mast cells by facilitating Syk activation, possibly as an adaptor molecule for Syk.
Effect of Temperature Variation on Adhesive Contact Force Behavior and Deformation of Substrate Based on Atomic Scale

Molecular dynamics method is performed to investigate the force behavior between semi-spherical indenter and single crystal substrate based on eam and morse potentials and verlet algorithm. Effects of different temperature on the contact force, friction force, and normal force are compared, the resistance of substrate material and dislocation movement are analyzed. It shows that the single crystal copper material’s resist deformation level is limited by low temperature, and more failure atoms were accumulated under the direction of indenter indenting in high temperature. More larger chip atoms volume were produced in front of indenter as sliding speed increases, and also the chip volume add with sliding distance increases. Furthermore,the dislocated band in basis lies at the angle of 45 degree with the movement direction of indenter in contact progress. This results have significance in improving contact performance and reducing the adhesive contact failure happens
