Precision measurement of the neutron spin asymmetries and spin-dependent structure functions in the valence quark region

Abstract: We report on measurements of the neutron spin asymmetries $A_{1,2}^n$ and polarized structure functions $g_{1,2}^n$ at three kinematics in the deep inelastic region, with $x=0.33$, 0.47 and 0.60 and $Q^2=2.7$, 3.5 and 4.8 (GeV/c)$^2$, respectively. These measurements were performed using a 5.7 GeV longitudinally-polarized electron beam and a polarized $^3$He target. The results for $A_1^n$ and $g_1^n$ at $x=0.33$ are consistent with previous world data and, at the two higher $x$ points, have improved the precision of the world data by about an order of magnitude. The new $A_1^n$ data show a zero crossing around $x=0.47$ and the value at $x=0.60$ is significantly positive. These results agree with a next-to-leading order QCD analysis of previous world data. The trend of data at high $x$ agrees with constituent quark model predictions but disagrees with that from leading-order perturbative QCD (pQCD) assuming hadron helicity conservation. Results for $A_2^n$ and $g_2^n$ have a precision comparable to the best world data in this kinematic region. Combined with previous world data, the moment $d_2^n$ was evaluated and the new result has improved the precision of this quantity by about a factor of two. When combined with the world proton data, polarized quark distribution functions were extracted from the new $g_1^n/F_1^n$ values based on the quark parton model. While results for $\Delta u/u$ agree well with predictions from various models, results for $\Delta d/d$ disagree with the leading-order pQCD prediction when hadron helicity conservation is imposed.

Hardiness and social support as moderators of stress.

Abstract: This study investigated the moderating effect of social support, hardiness, and the components of the hardiness scale of commitment, challenge, and control on the relationship between stress and depression. Hardiness, its components, and support were significantly correlated with scores on the Beck Depression Inventory (BDI). Hardiness and two components (commitment and control) were significantly correlated with stress. Stress was found to be a significant predictor of depression. Hardiness was shown to moderate the relationship between stress and depression such that high-stress, low-hardiness individuals had higher scores on the BDI than did low-stress, low-hardiness individuals. High-hardiness individuals had similar scores on the BDI regardless of their scores on stress. Support was shown to moderate the relationship between stress and depression such that high-stress, low-support individuals had higher scores on the BDI than did low-stress, low-support individuals. High-support individuals had similar scores on the BDI regardless of their scores on stress. Commitment was shown to moderate the relationship between stress and depression such that high-stress, low-commitment individuals had higher scores on the BDI than did low-stress, low-commitment individuals. High-commitment individuals had similar scores on the BDI regardless of their scores on stress.

Mourning beyond melancholia: Freud's psychoanalysis of loss

Abstract: Freud's mourning theory has been criticized for assuming a model of subjectivity based on a strongly bounded form of individuation. This model informs "Mourning and Melancholia" (1917), in which Freud argued that mourning comes to a decisive end when the subject severs its emotional attachment to the lost one and reinvests the free libido in a new object. Yet Freud revised his mourning theory in writings concerned with the Great War and in The Ego and the Id (1923), where he redefined the identification process previously associated with melancholia as an integral component of mourning. By viewing the character of the ego as an elegiac formation, that is, as "a precipitate of abandoned object-cathexes," Freud's later work registers the endlessness of normal grieving; however, it also imports into mourning the violent characteristics of melancholia, the internal acts of moralized aggression waged in an effort to dissolve the internal trace of the other and establish an autonomous identity. Because it is not immediately clear how Freud's text offers a theory of mourning beyond melancholy violence, his account of the elegiac ego is shown here to ultimately undermine the wish for an identity unencumbered by the claims of the lost other and the past, and to suggest the affirmative and ethical aspects of mourning.

Teaching Reading Fluency to Struggling Readers: Method, Materials, and Evidence

Abstract: Reading fluency has been identified as a key component in reading and in learning to read. Moreover, a significantly large number of students who experience difficulty in reading manifest difficulties in reading fluency that appear to contribute to their overall struggles in reading. In this article we explore the nature of effective instruction in fluency. We examine proven methods for teaching fluency as well as instructional routines that combine various methods into synergistic lessons. We also take issue with more mechanical approaches to fluency instruction that emphasize reading rate as the major goal of such instruction. Instead, we attempt to make the case for more authentic approaches to fluency instruction, approaches that employ texts meant to be practiced and performed.
