Poverty Amid Renewed Affluence: The Poor of New England at Mid-Decade

This article examines the problem of poverty in New England during the current period of economic prosperity. Major trends in the size and composition of the poor population within the region are analyzed. Striking changes in the relative incidence of poverty have occurred among families in New England. As the economy has moved toward full employment, poverty rates among husband-wife families in the region have fallen sharply. In contrast, female-headed families in New England have not benefited substantially from recent rapid increases in employment opportunities. The result has been a persistent trend toward the feminization of poverty in New England. The bulk of poor female family heads are of working age and could potentially be brought into the region\u27s work force. However, education and training services that can successfully attack fundamental barriers to labor force participation must be delivered to these women. Programs designed to overcome low levels of educational attainment and deficient basic skills must be combined with child care and other social services in order to further reduce overall poverty rates across the New England region

Investigating the Relationship Between Student Engagement and Transition

Failure to establish meaningful and effective transition for undergraduates can lead to academic underachievement. Student engagement represents a key component of student success. This study sought to investigate the impact of a bespoke transition programme featuring a wide range of innovative, student-centred activities on enhancing students’ engagement with educationally effective practices through examining student relations with others, learning and the discipline. For the study 104 undergraduates on a Sport Development course at a British university undertook a five-week transition programme. Data were collected via weekly questionnaires and focus groups at the end of weeks 1, 3 and 5. The investigation revealed that transition programmes require a high-intensity, novel and varied timetable supported by a student-centred staff team. Effective transition programmes can enhance students’ engagement with educationally effective practices. Future research should investigate the longer-term impact of such programmes

Identification and Functional Characterization of Toxoneuron nigriceps Ovarian Proteins Involved in the Early Suppression of Host Immune Response

The endophagous parasitoid Toxoneuron nigriceps (Viereck) (Hymenoptera, Braconidae) of the larval stages of the tobacco budworm Heliothis virescens (Fabricius) (Lepidoptera, Noctuidae) injects the egg, the venom, the calyx fluid, which includes a Polydnavirus (T. nigriceps BracoVirus: TnBV) and the Ovarian Proteins (OPs) into the host body during oviposition. The host metabolism and immune system are disrupted prematurely shortly after parasitization by the combined action of the TnBV, venom, and OPs. OPs are involved in the early suppression of host immune response, before TnBV infects and expresses its genes in the host tissues. In this work, we evaluated the effect of HPLC fractions deriving from in toto OPs. Two fractions caused a reduction in hemocyte viability and were subsequently tested to detect changes in hemocyte morphology and functionality. The two fractions provoked severe oxidative stress and actin cytoskeleton disruption, which might explain the high rate of hemocyte mortality, loss of hemocyte functioning, and hence the host\u2019s reduced hemocyte encapsulation ability. Moreover, through a transcriptome and proteomic approach we identify the proteins of the two fractions: eight proteins were identified that might be involved in the observed host hemocyte changes. Our findings will contribute to a better understanding of the secreted ovarian components and their role in parasitoid wasp strategy for evading host immune responses

Supplementary information accompanies this paper at doi:10.1038/s41598-017-01971-2.The question of how cell division orientation is determined is fundamentally important for understanding tissue and organ shape in both healthy or disease conditions. Here we provide evidence for cell contact-dependent orientation of planar cell division in the mammalian embryonic skin. We propose a model where the core planar polarity proteins Celsr1 and Frizzled-6 (Fz6) communicate the long axis orientation of interphase basal cells to neighbouring basal mitoses so that they align their horizontal division plane along the same axis. The underlying mechanism requires a direct, cell surface, planar polarised cue, which we posit depends upon variant post-translational forms of Celsr1 protein coupled to Fz6. Our hypothesis has parallels with contact-mediated division orientation in early C. elegans embryos suggesting functional conservation between the adhesion-GPCRs Celsr1 and Latrophilin-1. We propose that linking planar cell division plane with interphase neighbour long axis geometry reinforces axial bias in skin spreading around the mouse embryo body.Peer reviewe

KinImmerse: Macromolecular VR for NMR ensembles

<p>Abstract</p> <p>Background</p> <p>In molecular applications, virtual reality (VR) and immersive virtual environments have generally been used and valued for the visual and interactive experience – to enhance intuition and communicate excitement – rather than as part of the actual research process. In contrast, this work develops a software infrastructure for research use and illustrates such use on a specific case.</p> <p>Methods</p> <p>The Syzygy open-source toolkit for VR software was used to write the KinImmerse program, which translates the molecular capabilities of the kinemage graphics format into software for display and manipulation in the DiVE (Duke immersive Virtual Environment) or other VR system. KinImmerse is supported by the flexible display construction and editing features in the KiNG kinemage viewer and it implements new forms of user interaction in the DiVE.</p> <p>Results</p> <p>In addition to molecular visualizations and navigation, KinImmerse provides a set of research tools for manipulation, identification, co-centering of multiple models, free-form 3D annotation, and output of results. The molecular research test case analyzes the local neighborhood around an individual atom within an ensemble of nuclear magnetic resonance (NMR) models, enabling immersive visual comparison of the local conformation with the local NMR experimental data, including target curves for residual dipolar couplings (RDCs).</p> <p>Conclusion</p> <p>The promise of KinImmerse for production-level molecular research in the DiVE is shown by the locally co-centered RDC visualization developed there, which gave new insights now being pursued in wider data analysis.</p

Lifetime determination of excited states in Cd-106

Two separate experiments using the Differential Decay Curve Method have been performed to extract mean lifetimes of excited states in 106 Cd. The inedium-spin states of interest were populated by the Mo-98(C-12, 4n) Cd-106 reaction performed at the Wright Nuclear Structure Lab., Yale University. From this experiment, two isomeric state mean lifetimes have been deduced. The low-lying states were populated by the Mo-96(C-13, 3n)Cd-106 reaction performed at the Institut fur Kernphysik, Universitat zu Koln. The mean lifetime of the I-pi = 2(1)(+) state was deduced, tentatively, as 16.4(9) ps. This value differs from the previously accepted literature value from Coulomb excitation of 10.43(9) ps

A Communicating Branch Between the Musculocutaneous Nerve and the Median Nerve: A Case Report

Anatomical variations of peripheral nerves are commonly reported in the literature.&nbsp; While typically benign, they are of clinical importance as they can contribute to atypical clinical presentations, cause difficulty with imaging and nerve conduction studies, and lead to surgical challenges for surgeons.&nbsp; We report here a communicating branch between the musculocutaneous nerve and median nerve found during cadaveric dissection in a Doctor of Nursing Practice course in the Department of Nurse Anesthesia at Samford University.&nbsp; Although the case described here is among the most common anatomical variations of the peripheral nerves, there are classification systems for this variation that need to be recognized and applied by anatomists, clinicians, and surgeons

Bilateral Long Head of the Triceps Brachii Muscle Innervation via Axillary Nerve: A Case Report

The radial nerve has traditionally been considered the innervation of the long head of the triceps brachii (LHT). However, cadaveric studies have discovered LHT innervation via the axillary nerve in roughly 6-15 % of shoulders. A cadaver with exclusive axillary nerve innervation to the LHT bilaterally was discovered during cadaveric dissection in a graduate course at Samford University. This anatomical variation may have clinical implications for surgeries, shoulder dislocations, and quadrilateral space syndrome. Axillary nerve injuries may additionally present with shoulder extension and elbow extension weakness if this variation is present.&nbsp
