Reforming Juvenile Justice Requires Innovating Equity in Education

As many as 85 percent of students in juvenile justice are said to have some type of learning disability (National Council on Disability, 2015). A root cause analysis of indicators across societal systems reveals a pattern or chain of events which lead to this contemptible outcome. A contemptible outcome that represents the detriment of millions of children and families used to feed a cycle that erode the emotional and mental wellbeing not only of individuals, but the societies in which they live; not only erodes emotional and mental wellbeing but stands as a hallmark for the devaluing of human life. A contemptible outcome that must be interrupted. Research and best practices are available to disrupt this alarming statistic and with it reduce the number of students ever becoming systems-involved with juvenile justice. Using a synthesis of research and review of best practices, this article identifies problems, offers insights and strategies for intervention, revealing a solution that could put an end to the school-to-prison pipeline

Measurements of Gas Pressure into the MV Arc Plasma Environment

Current interrupters equipped with arc quenching system based on combination of forced air flow and gassing material were the object of the research described in this paper. Arc quenching gas pressure inside the extinguishing chamber in direct vicinity of plasma arc was recorded by means of developed measurement system resistant for heavy duty conditions existent inside the chamber during breaking. Gas pressure was estimated for several values of load current at 12/24 kV source voltage

40 Gbit/s silicon-organic hybrid (SOH) phase modulator

A 40 Gbit/s electro-optic modulator is demonstrated. The modulator is based on a slotted silicon waveguide filled with an organic material. The silicon organic hybrid (SOH) approach allows combining highly nonlinear electro-optic organic materials with CMOS-compatible silicon photonics technology

Quantum state tomography and quantum logical operations in a three qubits NMR quadrupolar system

In this work, we present an implementation of quantum logic gates and algorithms in a three effective qubits system, represented by a (I = 7/2) NMR quadrupolar nuclei. To implement these protocols we have used the strong modulating pulses (SMP). The various stages of each implementation were verified by quantum state tomography (QST). It is presented here the results for the computational base states, Toffolli logic gates, and Deutsch-Jozsa and Grover algorithms. Also, we discuss the difficulties and advantages of implementing such protocols using the SMP technique in quadrupolar systems.Comment: 24 pages, 8 figure

ESTABILIDADE DE UMA MISTURA DE SAIS FUNDIDOS CONTENDO LÍTIO PARA O ARMAZENAMENTO DE ENERGIA SOLAR TÉRMICA

Para o desenvolvimento das tecnologias de concentração solar térmica têm sido desenvolvidas misturas de sais, compostas principalmente por metais alcalinos/alcalino-terrosos, a serem utilizadas como meio de armazenamento de energia. A introdução de nitrato de lítio na mistura de nitratos de Na e K permite a diminuição do ponto de fusão da mistura, reduzindo assim os riscos de congelamento nas tubagens e tanques da instalação de armazenamento. Para avaliar a temperatura máxima de trabalho do sal ternário contendo lítio, foi efetuado o estudo da estabilidade térmica de uma mistura de sais fundidos de nitratos de Li-Na-K, em ensaios de longa duração (4000 h), ao ar, às temperaturas de 470 ºC e 490 ºC. As amostras retiradas ao longo do tempo foram caracterizadas por análise química, termogravimetria (TG/DTA-DSC) e por difração de raios-X (XRD) e comparadas com a mistura inicial (0 h), para avaliar a extensão da decomposição. Deste estudo concluiu-se que a mistura pode ser considerada termicamente estável até aos 470 ºC, com baixa decomposição de nitratos e baixa formação de óxidos e carbonato

Access and metro network convergence for flexible end-to-end network design

This paper reports on the architectural, protocol, physical layer, and integrated testbed demonstrations carried out by the DISCUS FP7 consortium in the area of access - metro network convergence. Our architecture modeling results show the vast potential for cost and power savings that node consolidation can bring. The architecture, however, also recognizes the limits of long-reach transmission for low-latency 5G services and proposes ways to address such shortcomings in future projects. The testbed results, which have been conducted end-to-end, across access - metro and core, and have targeted all the layers of the network from the application down to the physical layer, show the practical feasibility of the concepts proposed in the project

Opposing prognostic relevance of junction plakoglobin in distinct prostate cancer patient subsets

Both oncogenic and tumor suppressor functions have been described for junction plakoglobin (JUP), also known as γ-catenin. To clarify the role of JUP in prostate cancer, JUP protein expression was immunohistochemically detected in a tissue microarray containing 11 267 individual prostatectomy specimens. Considering all patients, high JUP expression was associated with adverse tumor stage (P = 0.0002), high Gleason grade (P < 0.0001), and lymph node metastases (P = 0.011). These associations were driven mainly by the subset without TMPRSS2:ERG fusion, in which high JUP expression was an independent predictor of poor prognosis (multivariate analyses, P = 0.0054) and early biochemical recurrence (P = 0.0003). High JUP expression was further linked to strong androgen receptor expression (P < 0.0001), high cell proliferation, and PTEN and FOXP1 deletion (P < 0.0001). In the ERG-negative subset, high JUP expression was additionally linked to MAP3K7 (P = 0.0007) and CHD1 deletion (P = 0.0021). Contrasting the overall prognostic effect of JUP, low JUP expression indicated poor prognosis in the fraction of CHD1-deleted patients (P = 0.039). In this subset, the association of high JUP and high cell proliferation was specifically absent. In conclusion, the controversial biological roles of JUP are reflected by antagonistic prognostic effects in distinct prostate cancer patient subsets
