Past as Prologue in the Affirmative Action Jurisprudence of the Supreme Court: Reflections on Fisher v. University of Texas at Austin and Schuette v. Coalition to Defend Affirmative Action

(Excerpt) This Article critically analyzes the dimensions and likely ramifications of Fisher and Schuette. The principle of pragmatic political proportionality eschews the wholly ideological extremist views that would either utterly vitiate affirmative action or deeply embed it as a substantially obsolete elitist residue of endless recalibrating. Instead, this Article subscribes to Lincolnian practical wisdom supplemented with a healthy dose of plain common sense. Enlightened political leadership should seek achievable pragmatic proportionality as the guiding principle controlling access to public institutions of higher education and, consequently, entry into the professions

Marking out the clinical expert/clinical leader/clinical scholar: Perspectives from nurses in the clinical arena

Background: Clinical scholarship has been conceptualised and theorised in the nursing literature for over 30 years but no research has captured nurses' clinicians' views on how it differs or is the same as clinical expertise and clinical leadership. The aim of this study was to determine clinical nurses' understanding of the differences and similarities between the clinical expert, clinical leader and clinical scholar.Methods: A descriptive interpretative qualitative approach using semi-structured interviews with 18 practising nurses from Australia, Canada and England. The audio-taped interviews were transcribed and the text coded for emerging themes. The themes were sorted into categories of clinical expert, clinical leader and clinical scholarship as described by the participants. These themes were then compared and contrasted and the essential elements that characterise the nursing roles of the clinical expert, clinical leader and clinical scholar were identified.Results: Clinical experts were seen as linking knowledge to practice with some displaying clinical leadership and scholarship. Clinical leadership is seen as a positional construct with a management emphasis. For the clinical scholar they linked theory and practice and encouraged research and dissemination of knowledge.Conclusion: There are distinct markers for the roles of clinical expert, clinical leader and clinical scholar. Nurses working in one or more of these roles need to work together to improve patient care. An 'ideal nurse' may be a blending of all three constructs. As nursing is a practice discipline its scholarship should be predominantly based on clinical scholarship. Nurses need to be encouraged to go beyond their roles as clinical leaders and experts to use their position to challenge and change through the propagation of knowledge to their community. © 2013 Mannix et al.; licensee BioMed Central Ltd

Practicing nurses perspectives of clinical scholarship: A qualitative study

Background: There is a scarcity of research published on clinical scholarship. Much of the conceptualisation has been conducted in the academy. Nurse academics espouse that the practice of nursing must be built within a framework of clinical scholarship. A key concept of clinical scholarship emerging from discussions in the literature is that it is an essential component of enabling evidence-based nursing and the development of best practice standards to provide for the needs of patients/clients. However, there is no comprehensive definition of clinical scholarship from the practicing nurses. The aim of this study was to contribute to this definitional discussion on the nature of clinical scholarship in nursing.Methods: Naturalistic inquiry informed the method. Using an interpretative approach 18 practicing nurses from Australia, Canada and England were interviewed using a semi-structured format. The audio-taped interviews were transcribed and the text coded for emerging themes. The themes were sorted into categories and the components of clinical scholarship described by the participants compared to the scholarship framework of Boyer [JHEOE 7:5-18, 2010].Results: Clinical scholarship is difficult to conceptualise. Two of the essential elements of clinical scholarship are vision and passion. The other components of clinical scholarship were building and disseminating nursing knowledge, sharing knowledge, linking academic research to practice and doing practice-based research.Conclusion: Academic scholarship dominated the discourse in nursing. However, in order for nursing to develop and to impact on health care, clinical scholarship needs to be explored and theorised. Nurse educators, hospital-based researchers and health organisations need to work together with academics to achieve this goal.Frameworks of scholarship conceptualised by nurse academics are reflected in the findings of this study with their emphasis on reading and doing research and translating it into nursing practice. This needs to be done in a nonthreatening environment. © 2013 Wilkes et al.; licensee BioMed Central Ltd

Resonant X-ray diffraction studies on the charge ordering in magnetite

Here we show that the low temperature phase of magnetite is associated with an effective, although fractional, ordering of the charge. Evidence and a quantitative evaluation of the atomic charges are achieved by using resonant x-ray diffraction (RXD) experiments whose results are further analyzed with the help of ab initio calculations of the scattering factors involved. By confirming the results obtained from X-ray crystallography we have shown that RXD is able to probe quantitatively the electronic structure in very complex oxides, whose importance covers a wide domain of applications.Comment: 4 pages 4 figures, accepted for publication in PR

Multiple prior concussions are associated with symptoms in high school athletes

Objectives: The purpose of this study was to evaluate the association of prior concussion on baseline computerized neurocognitive testing in a large cohort of high school athletes. Methods: This is a retrospective cohort study of student athletes from 49 Maine High Schools in 2010 who underwent baseline computerized neurocognitive evaluation with Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT®). As part of the ImPACT®, subjects reported a prior history of concussion as well as demographic information and a symptom questionnaire. We used linear regression to evaluate the association of prior concussion with baseline: (1) ImPACT® composite scores; and (2) symptom scores. Results: Six thousand seventy-five subjects were included in the study, of whom 57% were boys. The majority of student athletes (85.3%) reported no prior history of concussion while 4.6% reported having sustained two or more prior concussions. On simple linear regression, increasing number of concussions was related to worse performance in verbal memory (P = 0.039) and greater symptoms scores (P < 0.001). On multivariate modeling, only the association with baseline symptoms remained (P < 0.001). Other factors associated with baseline symptom reporting in the multivariate model included mental health history, headache/migraine history, gender, developmental and/or learning problems, and number of prior concussions. Interpretation In this large-scale, retrospective survey study, history of multiple prior concussions was associated with higher symptom burden but not baseline computerized neurocognitive testing. The association between baseline symptom reporting and clinical and demographic factors was greater than the association with a history of multiple concussions

Complex pattern of interaction between in utero hypoxia-ischemia and intra-amniotic inflammation disrupts brain development and motor function

Background: Infants born preterm commonly suffer from a combination of hypoxia-ischemia (HI) and infectious perinatal inflammatory insults that lead to cerebral palsy, cognitive delay, behavioral issues and epilepsy. Using a novel rat model of combined late gestation HI and lipopolysaccharide (LPS)-induced inflammation, we tested our hypothesis that inflammation from HI and LPS differentially affects gliosis, white matter development and motor impairment during the first postnatal month. Methods: Pregnant rats underwent laparotomy on embryonic day 18 and transient systemic HI (TSHI) and/or intra-amniotic LPS injection. Shams received laparotomy and anesthesia only. Pups were born at term. Immunohistochemistry with stereological estimates was performed to assess regional glial loads, and western blots were performed for protein expression. Erythropoietin ligand and receptor levels were quantified using quantitative PCR. Digigait analysis detected gait deficits. Statistical analysis was performed with one-way analysis of variance and post-hoc Bonferonni correction. Results: Microglial and astroglial immunolabeling are elevated in TSHI + LPS fimbria at postnatal day 2 compared to sham (both P < 0.03). At postnatal day 15, myelin basic protein expression is reduced by 31% in TSHI + LPS pups compared to shams (P < 0.05). By postnatal day 28, white matter injury shifts from the acute injury pattern to a chronic injury pattern in TSHI pups only. Both myelin basic protein expression (P < 0.01) and the phosphoneurofilament/neurofilament ratio, a marker of axonal dysfunction, are reduced in postnatal day 28 TSHI pups (P < 0.001). Erythropoietin ligand to receptor ratios differ between brains exposed to TSHI and LPS. Gait analyses reveal that all groups (TSHI, LPS and TSHI + LPS) are ataxic with deficits in stride, paw placement, gait consistency and coordination (all P < 0.001). Conclusions: Prenatal TSHI and TSHI + LPS lead to different patterns of injury with respect to myelination, axon integrity and gait deficits. Dual injury leads to acute alterations in glial response and cellular inflammation, while TSHI alone causes more prominent chronic white matter and axonal injury. Both injuries cause significant gait deficits. Further study will contribute to stratification of injury mechanisms in preterm infants, and guide the use of promising therapeutic interventions

Effectiveness of cognitive-behavioural therapy for depression in advanced cancer: CanTalk randomised controlled trial

BACKGROUND: Depression is one of the most common mental disorders in people with advanced cancer. Although cognitive-behavioural therapy (CBT) has been shown to be effective for depression in people with cancer, it is unclear whether this is the case for people with advanced cancer and depression. // AIMS: We sought to determine whether CBT is more clinically effective than treatment as usual (TAU) for treating depression in people with advanced cancer (trial registration number ISRCTN07622709). // METHOD: A multi-centre, parallel-group single-blind randomised controlled trial comparing TAU with CBT (plus TAU). Participants (n = 230) with advanced cancer and depression were randomly allocated to (a) up to 12 sessions of individual CBT or (b) TAU. The primary outcome measure was the Beck Depression Inventory-II (BDI-II). Secondary outcome measures included the Patient Health Questionnaire-9, the Eastern Cooperative Oncology Group Performance Status, and Satisfaction with Care. // RESULTS: Multilevel modelling, including complier-average intention-to-treat analysis, found no benefit of CBT. CBT delivery was proficient, but there was no treatment effect (-0.84, 95% CI -2.76 to 1.08) or effects for secondary measures. Exploratory subgroup analysis suggested an effect of CBT on the BDI-II in those widowed, divorced or separated (-7.21, 95% CI -11.15 to -3.28). // CONCLUSIONS: UK National Institute for Health and Care Excellence (NICE) guidelines recommend CBT for treating depression. Delivery of CBT through the Improving Access to Psychological Therapies (IAPT) programme has been advocated for long-term conditions such as cancer. Although it is feasible to deliver CBT through IAPT proficiently to people with advanced cancer, this is not clinically effective. CBT for people widowed, divorced or separated needs further exploration. Alternate models of CBT delivery may yield different results. // DECLARATION OF INTEREST: M.S. is a member of the Health Technology Assessment General Board
