Juror Internet Misconduct: A Survey of New Hampshire Superior Court Judges
[Excerpt] “The Constitution guarantees criminal defendants the right to a fair trial before an impartial jury and the right to confront the evidence against them. When a juror improperly accesses the Internet during a criminal trial, the defendant is denied these constitutional rights. The problem of outside information entering the courtroom is as old as our judicial system. As early as 1907, Justice Holmes observed that, “The theory of our [criminal justice] system is that the conclusions to be reached in a case will be induced only by evidence and argument in open court, and not by any outside influence, whether of private talk or public print.” Yet in recent years, the issue of juror misconduct has been brought to the forefront by striking examples of jurors seeking information on the Internet, outside of the evidence presented in court.
This Note examines the prevalence of Internet-related juror misconduct in the New Hampshire Superior Court and the efforts of Superior Court judges to detect and prevent such misconduct. I conducted a survey of New Hampshire Superior Court judges regarding their experience with juror Internet misconduct and solicited their feedback about a sample jury instruction. I have incorporated their feedback into a proposed set of jury instructions specifically targeted at reducing juror Internet misconduct.
Particle correlations and evidence for dark state condensation in a cold dipolar exciton fluid
In this paper we show experimental evidence of a few correlation regimes of a
cold dipolar exciton fluid, created optically in a semiconductor bilayer
heterostructure. In the higher temperature regime, the average interaction
energy between the particles shows a surprising temperature dependence which is
an evidence for correlations beyond the mean field model. At a lower
temperature, there is a sharp increase in the interaction energy of optically
active excitons, accompanied by a strong reduction in their apparent
population. This is an evidence for a sharp macroscopic transition to a dark
state as was suggested theoretically
Re-Sourcing school: Rethinking education in a connected world
Is school a waste of time? Is learning a waste of time? While for some the answer will be the same to both questions, most will agree that they are different questions and that difference is the heart of the issue that this paper seeks to confront. Over the last few years I have noted a number of things that might be called \u27dead canaries\u27. These are things that have signalled to me the scope of the issues that need to be confronted now and in the years ahead if we are to do our best in resourcing and re-sourcing education in a connected world
Growth of Hg1−xCdxTe single crystals by travelling heater method under accelerated crucible rotation conditions
The accelerated crucible rotation technique (ACRT) has been applied to the THM growth of Hg1−xCdxTe crystals to grow the crystals at a higher rate. These higher growth rates, which should be achieved by extending the regions of conventional stirring towards the interfaces, have been used in an attempt to explain the results in terms of simple constitutional supercooling arguments. Some different ACRT cycles which fulfil simple hydrodynamic and geometric criteria have been studied. The grown crystals were investigated with respect to their metallurgical homogeneity and their structural perfection. These properties have not been degraded by increasing the growth rate from 1.5 to 8.5 mm per day
Mechanical Characterization of Released Thin Films by Contact Loading
The design of reliable micro electro-mechanical systems (MEMS) requires understanding of material properties of devices, especially for free-standing thin structures such as membranes, bridges, and cantilevers. The desired characterization system for obtaining mechanical properties of active materials often requires load control. However, there is no such device among the currently available tools for mechanical characterization of thin films. In this paper, a new technique, which is load-controlled and especially suitable for testing highly fragile free-standing structures, is presented. The instrument developed for this purpose has the capability of measuring both the static and dynamic mechanical response and can be used for electro/magneto/thermo mechanical characterization of actuators or active materials. The capabilities of the technique are demonstrated by studying the behavior of 75 nm thick amorphous silicon nitride (Si_3N_4) membranes. Loading up to very large deflections shows excellent repeatability and complete elastic behavior without significant cracking or mechanical damage. These results indicate the stability of the developed instrument and its ability to avoid local or temporal stress concentration during the entire experimental process. Finite element simulations are used to extract the material properties such as Young's modulus and residual stress of the membranes. These values for Si_3N_4 are in close agreement with values obtained using a different technique, as well as those found in the literature. Potential applications of this technique in studying functional thin film materials, such as shape memory alloys, are also discussed
Spitz and wingless, emanating from distinct borders, cooperate to establish cell fate across the engrailed domain in the drosophila epidermis
A key step in development is the establishment of cell type diversity across a cellular field. Segmental patterning within the Drosophila embryonic epidermis is one paradigm for this process. At each parasegment boundary, cells expressing the Wnt family member Wingless confront cells expressing the homeoprotein Engrailed. The Engrailed-expressing cells normally differentiate as one of two alternative cell types. In investigating the generation of this cell type diversity among the 2-cell-wide Engrailed stripe, we previously showed that Wingless, expressed just anterior to the Engrailed cells, is essential for the specification of anterior Engrailed cell fate. In a screen for additional mutations affecting Engrailed cell fate, we identified anterior open/yan, a gene encoding an inhibitory ETS-domain transcription factor that is negatively regulated by the Rasl-MAP kinase signaling cascade. We find that Anterior Open must be inactivated for posterior Engrailed cells to adopt their correct fate. This is achieved by the EGF receptor (DER), which is required autonomously in the Engrailed cells to trigger the Ras1-MAP kinase pathway. Localized activation of DER is accomplished by restricted processing of the activating ligand, Spitz. Processing is confined to the cell row posterior to the Engrailed domain by the restricted expression of Rhomboid. These cells also express the inhibitory ligand Argos, which attenuates the activation of DER in cell rows more distant from the ligand source. Thus, distinct signals flank each border of the Engrailed domain, as Wingless is produced anteriorly and Spitz posteriorly. Since we also show that En cells have the capacity to respond to either Wingless or Spitz, these cells must choose their fate depending on the relative level of activation of the two pathways.Louise O’Keefe, Scott T.
