Needs of Military Families: Family and Educator Perspectives

This qualitative research study explores the problems military families, educators, and school districts have in building positive and effective partnerships. It is anticipated that a better understanding of the unique challenges encountered by military families and their children with developmental delays or exceptionalities will lead to more effective interventions. By understanding military families' needs and improving communication, more satisfying partnerships can be established, which in turn is anticipated to positively impact the well-being of the children with exceptionalities of military families. Little research exists to guide educators in finding effective strategies for supporting military families and their children with exceptionalities, particularly for young children (birth to eight years of age). Investigating programs and interventions which are effective for this age group is of particular importance, given that slightly more than 500,000 children of military families are under five years of age. Gaining a greater understanding of how to support these families is timely. We know from our work with families of young children with special needs that families are more satisfied and achieve a greater sense of empowerment when they are included as meaningful partners and respected for their knowledge. This family-centered approach, builds a "partnership of equals," collaborating to address challenges and build resources with families. For the military family, each new challenge taps new strengths and generates unique ideas for overcoming obstacles. This study suggests partnerships between the school leadership and military command could assist families with the challenges of relocation and deployment when they also have children with exceptionalities. Thus, implementing a family-centered approach in our work with military families should support the family as they work to enhance their family and child outcomes, build resilience, and achieve their long term goals with a sense of fulfillment

Attorney Liability Under the State Securities Laws: Landscapes and Minefields

Attorneys face significant liability exposure under the state securities laws, and they can be held primarily liable when they are sellers of securities, or under some state statutes, like California, when they are experts. Depending on the applicable jurisdiction and counsel\u27s status relative to the subject client, secondary liability may be incurred. In a number of states, counsel has liability exposure based on materially aiding the primary violator with the requisite intent. This article surveys and analyzes attorney liability under state securities law. After presenting a succinct overview of applicable state law in Part II, the article then provides a more in-depth analysis of attorney liability exposure under these state statutes in Part IIl. The article concludes in Part IV with separate treatment of two frequently invoked state statutes-those of California and Texas

Feature Nets: behavioural modelling of software product lines

Software product lines (SPL) are diverse systems that are developed using a dual engineering process: (a)family engineering defines the commonality and variability among all members of the SPL, and (b) application engineering derives specific products based on the common foundation combined with a variable selection of features. The number of derivable products in an SPL can thus be exponential in the number of features. This inherent complexity poses two main challenges when it comes to modelling: Firstly, the formalism used for modelling SPLs needs to be modular and scalable. Secondly, it should ensure that all products behave correctly by providing the ability to analyse and verify complex models efficiently. In this paper we propose to integrate an established modelling formalism (Petri nets) with the domain of software product line engineering. To this end we extend Petri nets to Feature Nets. While Petri nets provide a framework for formally modelling and verifying single software systems, Feature Nets offer the same sort of benefits for software product lines. We show how SPLs can be modelled in an incremental, modular fashion using Feature Nets, provide a Feature Nets variant that supports modelling dynamic SPLs, and propose an analysis method for SPL modelled as Feature Nets. By facilitating the construction of a single model that includes the various behaviours exhibited by the products in an SPL, we make a significant step towards efficient and practical quality assurance methods for software product lines

Strain dependence of the acoustic properties of amorphous metals below 1K: Evidence for the interaction between tunneling states

We have conducted a thorough study of the acoustic properties between 10^-4 and 1 Kelvin for the amorphous metal Zr_x Cu_1-x (x=0.3 and x=0.4), by measuring the relative change of sound velocity dv/v and internal friction Q^-1 as a function of temperature and also of the applied strain, in both superconducting and normal state. We have found that when plotted versus the ratio of strain energy to thermal energy, all measurements display the same behavior: a crossover from a linear regime of ``independent'' tunneling systems at very low strains and/or high enough temperatures to a nonlinear regime where dv/v and Q^-1 depend on applied strain and the tunneling systems cannot be considered as independent.Comment: 4 pages, 4 figures (submitted to PRL

The effect of pressure on statics, dynamics and stability of multielectron bubbles

The effect of pressure and negative pressure on the modes of oscillation of a multi-electron bubble in liquid helium is calculated. Already at low pressures of the order of 10-100 mbar, these effects are found to significantly modify the frequencies of oscillation of the bubble. Stabilization of the bubble is shown to occur in the presence of a small negative pressure, which expands the bubble radius. Above a threshold negative pressure, the bubble is unstable.Comment: 4 pages, 2 figures, accepted for publication in Physical Review Letter

Способ обработки крупногабаритных деталей

В данной статье приведены результаты исследования проблем обработки крупногабаритных деталей в условиях машиностроительных заводов Республики Казахстан. Исследования показали, что при обработке крупногабаритных деталей из труднообрабатываемых материалов возникают осевые и поперечные колебания, которые отрицательно сказываются на точности обработки и на стойкости режущего инструмента. Кроме этого существует проблема обработки крупногабаритных деталей с функционально связанными поверхностями. Для решения данных проблем предлагаются комбинированные способы обработки.This article presents the results of a study of the state of the problem of processing largesized parts in the conditions of machine-building plants of the Republic of Kazakhstan (RK). Studies have shown that when machining large parts from hard-to-digest materials, axial and lateral vibrations arise, which adversely affect machining accuracy and the resistance of the cutting tool. In addition, there is the problem of processing large parts with functionally connected surfaces. To solve these problems, combined treatment methods are proposed

Driving Errors in Parkinson’s Disease: Moving Closer to Predicting On-Road Outcomes

Age-related medical conditions such as Parkinson’s disease (PD) compromise driver fitness. Results from studies are unclear on the specific driving errors that underlie passing or failing an on-road assessment. In this study, we determined the between-group differences and quantified the on-road driving errors that predicted pass or fail on-road outcomes in 101 drivers with PD (mean age 5 69.38 ± 7.43) and 138 healthy control (HC) drivers (mean age 5 71.76 ± 5.08). Participants with PD had minor differences in demographics and driving habits and history but made more and different driving errors than HC participants. Drivers with PD failed the on-road test to a greater extent than HC drivers (41% vs. 9%), x2(1) 5 35.54, HC N 5 138, PD N 5 99, p \u3c .001. The driving errors predicting on-road pass or fail outcomes (95% confidence interval, Nagelkerke R2 5.771) were made in visual scanning, signaling, vehicle positioning, speeding (mainly underspeeding, t (61) 5 7.004, p \u3c .001, and total errors. Although it is difficult to predict on-road outcomes, this study provides a foundation for doing so

Fast-ion redistribution and loss due to edge perturbations in the ASDEX Upgrade, DIII-D and KSTAR tokamaks

The impact of edge localized modes (ELMs) and externally applied resonant and non-resonant magnetic perturbations (MPs) on fast-ion confinement/transport have been investigated in the ASDEX Upgrade (AUG), DIII-D and KSTAR tokamaks. Two phases with respect to the ELM cycle can be clearly distinguished in ELM-induced fast-ion losses. Inter-ELM losses are characterized by a coherent modulation of the plasma density around the separatrix while intra-ELM losses appear as well-defined bursts. In high collisionality plasmas with mitigated ELMs, externally applied MPs have little effect on kinetic profiles, including fast-ions, while a strong impact on kinetic profiles is observed in low-collisionality, low q(95) plasmas with resonant and non-resonant MPs. In low-collisionality H-mode plasmas, the large fast-ion filaments observed during ELMs are replaced by a loss of fast-ions with a broad-band frequency and an amplitude of up to an order of magnitude higher than the neutral beam injection prompt loss signal without MPs. A clear synergy in the overall fast-ion transport is observed between MPs and neoclassical tearing modes. Measured fast-ion losses are typically on banana orbits that explore the entire pedestal/scrape-off layer. The fast-ion response to externally applied MPs presented here may be of general interest for the community to better understand the MP field penetration and overall plasma response.Ministerio de Economía y Competitividad RYC-2011-09152, ENE2012-31087Marie Curie FP7 Integration PCIG11-GA-2012-321455US Department of Energy DE-FC02-04ER54698, SC-G903402, DEFG02- 04ER54761, DE-AC02-09CH11466, DE-FG02- 08ER54984NRF Korea 2009-008201
