    The role of the school principal has radically changed over the past half century. Many colleges of education are trying to develop alternative approaches to not only meet the needs of the adult learners who enroll in educational leadership preparation programs, but also to equip future school leaders with strategies for meeting the expectations set forth by the implementation and accountability of the No Child Left Behind legislation. The purpose of this study is to investigate whether a difference, if any, exists between individuals who graduated from the Boise State University (BSU) nontraditional educational leadership preparation program and a sample from across the nation. This mixed-method comparative case study will examine the following two research questions: (1) How effective are graduates of a non-traditional educational leadership preparation program (BSU) currently working as school principals/vice-principals compared to a national sample? And, (2) how, if at all, do these graduates/practicing principals perceive this non-traditional preparation program (BSU) to have contributed to their effectiveness? Quantitative data results from the Vanderbilt Assessment of Leadership in Education (VAL-EDTM) survey were used to provide a summary of the school principals’, teachers’, and immediate supervisors’ perceptions of the principals’ leadership effectiveness (and leadership behaviors) and were used to provide a comparison to a national sample. Qualitative data was also collected from semi-structured interviews with the BSU school principals to determine strengths and weaknesses of BSU’s educational leadership preparation program with a particular focus on which aspects of the program they felt made them effective. Results from the VAL-EDTM survey showed significant differences between BSU’s graduates’ overall effectiveness scores compared to a sample within the United States. Emerging themes from graduates’ interviews regarding the BSU Masters of Education in Educational Leadership (MEd Leadership Preparation) program included thinking differently, being people oriented, and connecting theory to practice. These three themes were developed by BSU MEd Leadership Preparation faculty working on problem-based learning scenarios, developing a trusting cohort structure, and utilizing practicing school administrators in various class discussions. Areas of improvement for the program consist of developing a network for post-graduates to draw upon and a stronger focus on school law

    Altres ajuts: acords transformatius de la UABPurpose of review This review focuses on the role of psychologists in the assessment and treatment of fibromyalgia syndrome (FMS), a highly prevalent condition characterized by chronic widespread pain, fatigue, cognitive problems, distress, and disability. Recent findings A large body of work supports the effectiveness and cost-utility of psychological therapies for the improvement of a wide range of symptoms associated with FMS. However, patients with FMS are best assessed and treated by a multidisciplinary team, in which psychologists have an important role. Multidisciplinary treatment, in which each healthcare professional offers his or her own expertise to the patient, has been shown to produce more ubiquitous treatment effects for this complex syndrome than single discipline treatments. Considering the empirical evidence and documented experience of patients, people with FMS can benefit from integrated care, combining education, exercise, and psychotherapeutic approaches, including cognitive-behavioral therapy. Summary There has been a call for more health economics research to demonstrate the cost-effectiveness of psychological therapies. In this paper, we highlight the added value of psychologists as members of multidisciplinary treatment teams, who can assess and treat the maladaptive cognitive, emotional, and behavioral symptoms that are commonly seen in individuals with FMS

    The Department of Energy's (DOE's) Generation IV Nuclear Energy Systems Program will address the research and development (R&D) necessary to support next-generation nuclear energy systems. Such R&D will be guided by the technology roadmap developed for the Generation IV International Forum (GIF) over two years with the participation of over 100 experts from the GIF countries. The roadmap evaluated over 100 future systems proposed by researchers around the world. The scope of the R&D described in the roadmap covers the six most promising Generation IV systems. The effort ended in December 2002 with the issue of the final Generation IV Technology Roadmap [1.1]. The six most promising systems identified for next generation nuclear energy are described within the roadmap. Two employ a thermal neutron spectrum with coolants and temperatures that enable hydrogen or electricity production with high efficiency (the Supercritical Water Reactor - SCWR and the Very High Temperature Reactor - VHTR). Three employ a fast neutron spectrum to enable more effective management of actinides through recycling of most components in the discharged fuel (the Gas-cooled Fast Reactor - GFR, the Lead-cooled Fast Reactor - LFR, and the Sodium-cooled Fast Reactor - SFR). The Molten Salt Reactor (MSR) employs a circulating liquid fuel mixture that offers considerable flexibility for recycling actinides, and may provide an alternative to accelerator-driven systems. A few major technologies have been recognized by DOE as necessary to enable the deployment of the next generation of advanced nuclear reactors, including the development and qualification of the structural materials needed to ensure their safe and reliable operation. Accordingly, DOE has identified materials as one of the focus areas for Gen IV technology development

    Genome of the marsupial Monodelphis domestica reveals innovation in non-coding sequences

    We report a high-quality draft of the genome sequence of the grey, short-tailed opossum (Monodelphis domestica). As the first metatherian (\u27marsupial\u27) species to be sequenced, the opossum provides a unique perspective on the organization and evolution of mammalian genomes. Distinctive features of the opossum chromosomes provide support for recent theories about genome evolution and function, including a strong influence of biased gene conversion on nucleotide sequence composition, and a relationship between chromosomal characteristics and X chromosome inactivation. Comparison of opossum and eutherian genomes also reveals a sharp difference in evolutionary innovation between protein-coding and non-coding functional elements. True innovation in protein-coding genes seems to be relatively rare, with lineage-specific differences being largely due to diversification and rapid turnover in gene families involved in environmental interactions. In contrast, about 20% of eutherian conserved non-coding elements (CNEs) are recent inventions that postdate the divergence of Eutheria and Metatheria. A substantial proportion of these eutherian-specific CNEs arose from sequence inserted by transposable elements, pointing to transposons as a major creative force in the evolution of mammalian gene regulation. ©2007 Nature Publishing Group

    Background The immunological escape of tumors represents one of the main ob- stacles to the treatment of malignancies. The blockade of PD-1 or CTLA-4 receptors represented a milestone in the history of immunotherapy. However, immune checkpoint inhibitors seem to be effective in specific cohorts of patients. It has been proposed that their efficacy relies on the presence of an immunological response. Thus, we hypothesized that disruption of the PD-L1/PD-1 axis would synergize with our oncolytic vaccine platform PeptiCRAd. Methods We used murine B16OVA in vivo tumor models and flow cytometry analysis to investigate the immunological background. Results First, we found that high-burden B16OVA tumors were refractory to combination immunotherapy. However, with a more aggressive schedule, tumors with a lower burden were more susceptible to the combination of PeptiCRAd and PD-L1 blockade. The therapy signifi- cantly increased the median survival of mice (Fig. 7). Interestingly, the reduced growth of contralaterally injected B16F10 cells sug- gested the presence of a long lasting immunological memory also against non-targeted antigens. Concerning the functional state of tumor infiltrating lymphocytes (TILs), we found that all the immune therapies would enhance the percentage of activated (PD-1pos TIM- 3neg) T lymphocytes and reduce the amount of exhausted (PD-1pos TIM-3pos) cells compared to placebo. As expected, we found that PeptiCRAd monotherapy could increase the number of antigen spe- cific CD8+ T cells compared to other treatments. However, only the combination with PD-L1 blockade could significantly increase the ra- tio between activated and exhausted pentamer positive cells (p= 0.0058), suggesting that by disrupting the PD-1/PD-L1 axis we could decrease the amount of dysfunctional antigen specific T cells. We ob- served that the anatomical location deeply influenced the state of CD4+ and CD8+ T lymphocytes. In fact, TIM-3 expression was in- creased by 2 fold on TILs compared to splenic and lymphoid T cells. In the CD8+ compartment, the expression of PD-1 on the surface seemed to be restricted to the tumor micro-environment, while CD4 + T cells had a high expression of PD-1 also in lymphoid organs. Interestingly, we found that the levels of PD-1 were significantly higher on CD8+ T cells than on CD4+ T cells into the tumor micro- environment (p < 0.0001). Conclusions In conclusion, we demonstrated that the efficacy of immune check- point inhibitors might be strongly enhanced by their combination with cancer vaccines. PeptiCRAd was able to increase the number of antigen-specific T cells and PD-L1 blockade prevented their exhaus- tion, resulting in long-lasting immunological memory and increased median survival

    piloted simulation study was conducted at the National Aeronautics and Space Administration (NASA) Langley Research Center (LaRC) to evaluate the ability to safely conduct surface trajectory-based operations (STBO) by assessing the impact of providing traffic intent information, conflict detection and resolution (CD&R) system capability, and the display of STBO guidance to the flight crew on both head-down and head-up displays (HUD). Nominal and off-nominal conflict scenarios were conducted using 12 airline crews operating in a simulated Memphis International Airport terminal environment. The flight crews met their required time-of-arrival at route end within 10 seconds on 98 percent of the trials, well within the acceptable performance bounds of 15 seconds. Traffic intent information was found to be useful in determining the intent of conflict traffic, with graphical presentation preferred. The CD&R system was only minimally effective during STBO because the prevailing visibility was sufficient for visual detection of incurring traffic. Overall, the pilots indicated STBO increased general situation awareness but also negatively impacted workload, reduced the ability to watch for other traffic, and increased head-down time
