State v. Henderson: A Model for Admitting Eyewitness Identification Testimony

Eyewitness identification testimony is notoriously unreliable and has significantly contributed to wrongful convictions. Most courts use the standard set forth by the Supreme Court in Manson v. Brathwaite to assess whether eyewitness identifications are sufficiently reliable to present to the jury. But in the thirty-five years since Manson, an extensive body of research has amassed that calls into question the continuing validity of that standard. Researchers have identified numerous system variables (procedural elements subject to official control) and estimator variables (factors related to the witness, perpetrator, and event) that affect the accuracy of eyewitness identifications. The Manson standard fails to account for most of these factors. In response, the New Jersey Supreme Court in State v. Henderson retooled its state constitutional due process test for admitting eyewitness identification testimony and mandated more comprehensive jury instructions that warn jurors of the vulnerability of eyewitness identifications to both system and estimator variables. Until the Supreme Court is willing to revise the Manson v. Brathwaite standard, state courts should consider adopting more comprehensive due process requirements, as well as jury instructions that better embody the current state of scientific understanding about the complexities of memory and the fallibility of eyewitnesse

Characterization and causes of multi-timescale sea level and thermocline depth variability in the tropical southern Indian Ocean

In this study a hierarchy of numerical models and a suite of diagnostic numerical experiments are used to characterize the spatial and temporal structure of sea level and thermocline depth variations in the southern Indian Ocean. The key physical processes responsible for driving the multi-timescale variability are then identified. Particular emphasis is placed on the Thermocline Ridge of the Indian Ocean (TRIO), a region in the southwestern tropical Indian Ocean where variations in thermocline depth are suggested to affect sea surface temperature and thus climate. On seasonal-to-decadal timescales, the key physical processes that contribute to variability of the TRIO are timescale dependent and largely arise from wind forcing acting on the Indian Ocean. Seasonally, variability of the TRIO results from a combination of local Ekman pumping and the arrival of Rossby waves forced by winds east of region. Interannually, variability is associated with westward-propagating Rossby waves forced by the Ekman pumping velocities east of the ridge. Remote oceanic forcing from the Pacific has significant influence on the seasonal and interannual thermocline variability in the eastern basin, but a weak impact in the tropical ocean interior. On decadal timescales, sea level and thermocline depth variability peaks in the southwestern Indian Ocean in both the tropics and subtropics. Prior to the early 1990s, low frequency variations in sea level and thermocline depth in the tropics, can be described as a baroclinic Sverdrup balance, forced by windstress acting on the Indian Ocean. Beginning in the early 90\u27s, decadal variability of the equatorial Pacific trade winds forces thermocline variations that modify the sea level and thermocline depth across the entire tropical southern Indian Ocean basin. Farther south, nonlinearities of the flow appear to dominate the low frequency variability in the ocean interior. On multi-decadal timescales, the TRIO has experienced a shoaling trend spanning 1961-2000. This shoaling is consistent with regional enhanced upward Ekman pumping velocity and spin-up of the southern Indian Ocean subtropical cell

Immigrant Cosmopolitanism: Jewish-American Immigrant Narratives and Modernist Cosmopolitan Aesthetics

I propose to show in this study how Jewish-American authors of mass media immigrant works from the first three decades of the 20th century utilize a form of modernist cosmopolitan aesthetics to challenge notions that these works are unworthy of study and appreciation. These authors, not happy with the classifications and aesthetics available to them as immigrant authors, borrow from other ideologies and aesthetic schools to create an aesthetic system meeting the needs of immigrant individuals. In theory, this system, which I have termed \u27immigrant cosmopolitanism,\u27 meets the needs of these individuals and capitalizes on the authors\u27 diverse backgrounds and experiences. Only these authors can decide which aesthetics adequately relate their story, and they believe immigrant cosmopolitanism will give them the freedom to tell their stories in a way previously denied them. However, they find that no pure aesthetic, cosmopolitan, modernist, or otherwise, can fully convey their stories. Pure modernist cosmopolitanism leaves little room for the integration of those ethnic details and personal experiences necessary for these texts to function successfully as immigrant novels. Therefore, these authors intend to find an aesthetic allowing them to tell their individual immigrant stories in a way highlighting their intellectualism and artistry. Immigrant cosmopolitanism allows them to relate their stories in the manner they desire and in a way representing immigrant lives: it is a hybrid of popular and intellectual, artistic and commodified, hopeful and cynical, and it ultimately fails to accomplish its goals (just as these Jewish-American immigrant authors fail in their attempts to be seen as something more than just immigrant authors)

Are Midtwentieth Century Forced Changes in North Atlantic Hurricane Potential Intensity Detectable?

The impact of anthropogenic forcings on tropical North Atlantic hurricane potential intensity (PI) is evaluated in Climate Model Intercomparison Project 5 models for the period 1958–2005. Eleven models are examined, but only seven models have a forced response that is distinguishable from internal variability. The use of discriminant analysis to optimize detectability does not yield a clear, common climate change signal. Of the seven models with a significant response, one has a negative linear trend while two have a positive linear trend. The trend in PI is not even consistent among reanalyses, although this difference is not statistically significant because of large uncertainties. Furthermore, estimates of PI internal variability have significantly different variances among different reanalysis products. These disagreements between models, reanalysis products, and between models and reanalyses, in conjunction with relatively large uncertainties, highlight the difficulty of detecting and attributing observed changes in North Atlantic hurricane potential intensity

Application of 13C flux analysis to determine impacts of media alterations on industrial CHO cell metabolism

Industrial bioprocesses place extraordinary demands on the metabolism of host cells to meet the biosynthetic requirements for maximal growth and protein production. Identifying host cell metabolic phenotypes that promote high recombinant protein titer is a major goal of the biotech industry. 13C metabolic flux analysis (MFA) provides a rigorous approach to quantify these metabolic phenotypes by applying stable isotope tracers to map the flow of carbon through intracellular metabolic pathways. We have conducted a series of 13C MFA studies to examine the metabolic impacts of altering the composition of a proprietary chemically defined growth medium on CHO cell metabolism. CHO cell cultures characteristically produce excess ammonia and lactate as byproducts, both of which are toxic at high concentrations. Whereas lactate is often consumed during stationary growth phase in CHO cell cultures, ammonia continues to accumulate in the extracellular media throughout the course of cell growth due mainly to glutamine catabolism. For CHO cells that utilize glutamine, rational media design can alleviate ammonia stress from the cell culture. However, manipulating carbon sources in the growth medium can also have negative effects on cellular metabolism such as decreased culture growth, viability, recombinant protein productivity, or longevity. This study highlights a rationally engineered cell culture medium that successfully reduces culture ammonia levels by 40% while maintaining the original metabolic phenotype. First, the basal media developed in-house by Sanofi was chemically altered to cause CHO cells to produce significantly less ammonia byproduct. This low ammonia-producing media variant was experimentally developed by altering the ratio of carbon sources in the media to strategically reduce flux through metabolic pathways that result in ammonia production while supplementing complementary, non-ammonia producing pathways to balance metabolism. This altered media variant successfully decreased the ammonia concentration in industrial CHO while maintaining culture growth, viability, and specific productivity. Parallel 13C MFA studies were performed on IgG-producing CHO cells grown identically in three media variants: the basal control media, the low-ammonia media, and the low-ammonia media supplemented with basal ammonia levels. The latter media was used to control for any direct effects of changing ammonia concentrations on cellular metabolism. 13C labeling studies utilizing [U-13C5]glutamine and [1,213C2]glucose were carried out in parallel for each condition. From the comparison of the 13C flux analysis across the three media types, we have concluded that the media alterations did not have a significant impact on the intracellular metabolism of CHO cultures. This suggests that Sanofi can use their newly developed media formulation to decrease toxic ammonia buildup in IgG-producing CHO cell lines without significantly altering host metabolic phenotype or productivit

Cognitive, affective and social mechanisms in depression risk: cognition, hostility, and coping style

Although some research has assessed cognitive variables in individuals at risk for depression, few studies have specifically assessed the role of automatic thinking, and virtually no studies have assessed anger and coping in this group. The current study compared measures of these variables in a high-risk group that was defined on the basis of a previous episode of depression, and a control group comprised of low-risk/never depressed individuals. Even though neither group evidenced depressive symptoms at the time of assessment, group comparisons and regression analyses indicated that high-risk individuals reported more negative automatic thoughts than did low-risk participants and that social support seeking, self-blame, and avoidance emerged as coping predictors of risk as did higher levels of anger and hostility. These data thus suggest patterns of interpersonal, behavioural, and cognitive variables that may characterise depression risk. A number of factors make depression a significant public-health concern. Depression is not only associated with substantial emotional distress and psychological impairment, but also with impaired interpersonal, marital, and occupational functionin
