The Justice Against Sponsors of Terrorism Act: An Infringement on Executive Power

In the more than sixteen years since September 11, 2001, the United States has resolved, through policy at home and abroad, to vindicate the heroes and victims of that attack. From the creation of the Department of Homeland Security, to the raid that resulted in the death of Osama Bin Laden, the shockwaves of 9/11 have reverberated through America’s domestic and foreign policy ever since. In the only veto override of the Obama presidency, the 114th U.S. Congress brought the Justice Against Sponsors of Terrorism Act (“JASTA”) into force, intending to provide U.S. citizens with a basis to seek relief against persons, entities, and foreign governments that offered material support to terrorist acts occurring on or after 9/11. Now, empowered by Congress, private citizens and the courts can disrupt the President’s unified foreign policy with respect to the suspect nation, an impermissible violation of the separation of powers doctrine. This Note argues that JASTA unconstitutionally allows private litigants and the courts to delve into the executive foreign affairs power, determining America’s stance on another nation’s responsibility for international terrorism

Adolescent Literacy, Identity and School (ALIAS): positions, pedagogies and spaces for learning

The purpose of this paper is to excavate connections between adolescent literacy and identity in post-primary school settings. It will focus on the theoretical framework informing our study as well as a brief discussion of some key findings. The central research aims focusing this part of the Adolescent Literacy, Identity and School (ALIAS) study are to: (i) Investigate the impact of levels of literacy and learning on the identity constructions of first year students in post-primary school (ii) To develop guidelines for a cross-curricular literacy and learning intervention programme in collaboration with student participants

Views from the margins: teacher perspectives on alternative education provision in Ireland

Alternative education provision in Ireland is under-researched. This paper is a qualitative investigation of the perspectives of a purposive sample of ten teachers on curriculum, pedagogy and assessment in their respective alternative settings of a voluntary education centre, a Youthreach centre and a post-primary special school. ‘Funds of knowledge’ ideas contribute to the theoretical framework of the study [Moll, Luis C., Cathy Amanti, Deborah Neff, and Norma Gonzalez. 1992. ‘Funds of Knowledge for Teaching: Using a Qualitative Approach to Connect Homes and Classrooms.’ Theory Into Practice 31 (2): 132–141]. The findings in this paper focus on: (1) how curriculum is enacted and mediated in alternative education settings; (2) the pedagogical decisions of teachers as they strive to connect their students to learning and (3) the tensions in assessment practices as teachers and alternative settings attempt to provide authentic and yet certified evidence of learning through the formal state assessment processes. This article is timely as it offers a view of the under-researched area of alternative settings in Ireland

Dark Matter in the Coming Decade: Complementary Paths to Discovery and Beyond

In this report we summarize the many dark matter searches currently being pursued through four complementary approaches: direct detection, indirect detection, collider experiments, and astrophysical probes. The essential features of broad classes of experiments are described, each with their own strengths and weaknesses. The complementarity of the different dark matter searches is discussed qualitatively and illustrated quantitatively in two simple theoretical frameworks. Our primary conclusion is that the diversity of possible dark matter candidates requires a balanced program drawing from all four approaches.Comment: Report prepared for the Community Summer Study (Snowmass) 2013, on behalf of Cosmic Frontier Working Groups 1-4 (CF1: WIMP Dark Matter Direct Detection, CF2: WIMP Dark Matter Indirect Detection, CF3: Non-WIMP Dark Matter, and CF4: Dark Matter Complementarity); published versio

Light Induction of a Vertebrate Clock Gene Involves Signaling through Blue-Light Receptors and MAP Kinases

AbstractThe signaling pathways that couple light photoreception to entrainment of the circadian clock have yet to be deciphered. Two prominent groups of candidates for the circadian photoreceptors are opsins (e.g., melanopsin) and blue-light photoreceptors (e.g., cryptochromes). We have previously showed that the zebrafish is an ideal model organism in which to study circadian regulation and light response in peripheral tissues. Here, we used the light-responsive zebrafish cell line Z3 to dissect the response of the clock gene zPer2 to light. We show that the MAPK (mitogen-activated protein kinase) pathway is essential for this response, although other signaling pathways may also play a role. Moreover, action spectrum analyses of zPer2 transcriptional response to monochromatic light demonstrate the involvement of a blue-light photoreceptor. The Cry1b and Cry3 cryptochromes constitute attractive candidates as photoreceptors in this setting. Our results establish a link between blue-light photoreceptors, probably cryptochromes, and the MAPK pathway to elicit light-induced transcriptional activation of clock genes

Atorvastatin ameliorates cerebral vasospasm and early brain injury after subarachnoid hemorrhage and inhibits caspase-dependent apoptosis pathway

<p>Abstract</p> <p>Backgroud</p> <p>Cerebral vasospasm (CVS) and early brain injury remain major causes of morbidity and mortality after aneurysmal subarachnoid hemorrhage (SAH). Hydroxymethylglutaryl coenzyme A reductase inhibitors, also known as statins, has the neuroprotective effects and ameliorating CVS after SAH. This study was designed to explore apoptosis inhibiting effects of atorvastatin and its potential apoptotic signal pathway after SAH.</p> <p>Results</p> <p>Preserving blood-brain-barrier permeability, decreasing brain edema, increasing neurological scores and ameliorating cerebral vasospasm were obtained after prophylactic use of atorvastatin. TUNEL-positive cells were reduced markedly both in basilar artery and in brain cortex by atorvastatin. Apoptosis-related proteins P53, AIF and Cytochrome C were up-regulated after SAH, while they were not affected by atorvastatin. In addition, up-regulation of caspase-3 and caspase-8 after SAH was decreased by atorvastatin treatment both in mRNA and in protein levels.</p> <p>Conclusion</p> <p>The neuroprotective effects of atorvastatin after SAH may be related to its inhibition of caspase-dependent proapoptotic pathway based on the present results.</p

Could lymphatic mapping and sentinel node biopsy provide oncological providence for local resectional techniques for colon cancer? A review of the literature

<p>Abstract</p> <p>Background</p> <p>Endoscopic resectional techniques for colon cancer are undermined by their inability to determine lymph node status. This limits their application to only those lesions at the most minimal risk of lymphatic dissemination whereas their technical capacity could allow intraluminal or even transluminal address of larger lesions. Sentinel node biopsy may theoretically address this breach although the variability of its reported results for this disease is worrisome.</p> <p>Methods</p> <p>Medline, EMBASE and Cochrane databases were interrogated back to 1999 to identify all publications concerning lymphatic mapping for colon cancer with reference cross-checking for completeness. All reports were examined from the perspective of in vivo technique accuracy selectively in early stage disease (i.e. lesions potentially within the technical capacity of endoscopic resection).</p> <p>Results</p> <p>Fifty-two studies detailing the experiences of 3390 patients were identified. Considerable variation in patient characteristics as well as in surgical and histological quality assurances were however evident among the studies identified. In addition, considerable contamination of the studies by inclusion of rectal cancer without subgroup separation was frequent. Indeed such is the heterogeneity of the publications to date, formal meta-analysis to pool patient cohorts in order to definitively ascertain technique accuracy in those with T1 and/or T2 cancer is not possible. Although lymphatic mapping in early stage neoplasia alone has rarely been specifically studied, those studies that included examination of false negative rates identified high T3/4 patient proportions and larger tumor size as being important confounders. Under selected circumstances however the technique seems to perform sufficiently reliably to allow it prompt consideration of its use to tailor operative extent.</p> <p>Conclusion</p> <p>The specific question of whether sentinel node biopsy can augment the oncological propriety for endoscopic resective techniques (including Natural Orifice Transluminal Endoscopic Surgery [NOTES]) cannot be definitively answered at present. Study heterogeneity may account for the variability evident in the results from different centers. Enhanced capacity (perhaps to the level necessary to consider selective avoidance of en bloc mesenteric resection) by its confinement to only early stage disease is plausible although not proven. Specific study of the technique in early stage tumors is clearly essential before proffering this approach.</p

Sequencing of prostate cancers identifies new cancer genes, routes of progression and drug targets

Prostate cancer represents a substantial clinical challenge because it is difficult to predict outcome and advanced disease is often fatal. We sequenced the whole genomes of 112 primary and metastatic prostate cancer samples. From joint analysis of these cancers with those from previous studies (930 cancers in total), we found evidence for 22 previously unidentified putative driver genes harboring coding mutations, as well as evidence for NEAT1 and FOXA1 acting as drivers through noncoding mutations. Through the temporal dissection of aberrations, we identified driver mutations specifically associated with steps in the progression of prostate cancer, establishing, for example, loss of CHD1 and BRCA2 as early events in cancer development of ETS fusion-negative cancers. Computational chemogenomic (canSAR) analysis of prostate cancer mutations identified 11 targets of approved drugs, 7 targets of investigational drugs, and 62 targets of compounds that may be active and should be considered candidates for future clinical trials
