The Root mission
The purpose of this study is to examine the Root Mission to Russia from it conception to its final report and to evaluate the effectiveness of each member individually as well as that of the Mission as a whole. Further, major actions and responses of the Wilson Administration and other American officials have been considered where these actions have a direct bearing on the effectiveness of the Root Mission. This study also provides a narrative account of the constructive work of the commission and attempts to highlight those experiences which might well have had a significant impact on the Mission\u27s understanding of the Russian situation. It is not the purpose of this study to provide a definitive account of all aspects of the Root Mission, its members, or the Wilson Administration\u27s relations with Russia during this period. Nevertheless, this work does examine the majority of available sources relating to the Root Mission, its members, and the administration during this period of American History.
The scope of this paper is limited to the presentation of the actions, experiences, and viewpoints of the mission and its individual members both as to the Russian situation and to the actions of the administration. Naturally much of the correspondence between the President, Secretary of State Lansing, and other important Americans has been included.
It is not within the scope of this Paper to provide a definitive study of internal administration and State Department communications or to examine, in depth, the Russian reactions to the Root Mission or its members. All primary Russian sources contained herein were those that were translated for Root Mission personnel and can be found in American sources. Most secondary Russian sources on this period have little bearing on the Mission but often provide interesting background information. Several important subtopics require further study that is beyond the scope of this paper. These include internal State Department communications, Russian newspaper reactions to the Root Mission, and the activities of Charles R. Crane. Neither the primary nor secondary sources used in this study document or strongly suggest any other conclusion than the one I have reached. It is important to note, however, that the motivation behind the inaction of Wilson, Lansing, and other important American officials on the issue of a major propaganda campaign remains in doubt and to my knowledge undocumentable

Socioeconomic risk, parenting during the preschool years and child health age 6 years
Parent–child relationships and parenting processes are emerging as potential life course
determinants of health. Parenting is socially patterned and could be one of the factors responsible for
the negative effects of social inequalities on health, both in childhood and adulthood. This study tests
the hypothesis that some of the effect of socioeconomic risk on health in mid childhood is transmitted
via early parenting. Methods: Prospective cohort study in 10 USA communities involving 1041 mother/
child pairs, selected at birth at random with conditional sampling. Exposures: income, maternal
education, maternal age, lone parenthood, ethnic status and objective assessments of mother child
interaction in the first 4 years of life covering warmth, negativity and positive control. Outcomes:
mother’s report of child’s health in general at 6 years. Modelling: multiple regression analyses with
statistical testing of mediational processes. Results: All five indicators of socioeconomic status (SES) were
correlated with all three measures of parenting, such that low SES was associated with poor parenting.
Among the measures of parenting maternal warmth was independently predictive of future health, and
among the socioeconomic variables maternal education, partner presence and ‘other ethnic group’
proved predictive. Measures of parenting significantly mediated the impact of measures of SES on child
health. Conclusions: Parenting mediates some, but not all of the detectable effects of socioeconomic
risk on health in childhood. As part of a package of measures that address other determinants,
interventions to support parenting are likely to make a useful contribution to reducing childhood
inequalities in health
GEOSAT Follow-On (GFO) Altimeter Document Series, Volume 8: GFO Altimeter Engineering Assessment Report Update:The First 109 Cycles Since Acceptance November 29, 2000 to December 26, 2005
The purpose of this document is to present and document GFO performance analyses and results. This is the fifth Assessment Report since the initial report. This report extends the performance assessment since acceptance to 26 December 2005. The initial GFO Altimeter Engineering Assessment Report, March 2001 (NASA/TM-2001-209984/Ver.1/Vol.1) covered the GFO performance from Launch to Acceptance (10 February 1998 to 29 November 2000). The second of the series covered the performance from Acceptance to the end of Cycle 20 (29 November 2000 to 21 November 2001). The third of the series covered the performance from Acceptance to the end of Cycle 42 (29 November 2000 to 30 November 2002). The fourth of the series covered the performance from Acceptance to the end of Cycle 64 (29 November 2000 to 17 December 2003). The fifth of the series covered performance from Acceptance to the end of Cycle 86 (29 November 2000 to 17 December 2004). Since launch, we have performed a variety of GFO performance studies; an accumulative index of those studies is provided in Appendix A
GFO and JASON Altimeter Engineering Assessment Report. Update: GFO-Acceptance to End of Mission on October 22, 2008, JASON-Acceptance to September 29, 2008
The purpose of this document is to present and document GEOSAT Follow-On (GFO) performance analyses and results. This is the ninth Assessment Report since the initial report and is our final one. This report extends the performance assessment since acceptance on November 29, 2000 to the end of mission (EOM) on October 22, 2008. Since launch, February 10, 1998 to the EOM, we performed a variety of GFO performance studies; Appendix A provides an accumulative index of those studies. We began the inclusion of analyses of the JASON altimeter after the end of the Topographic Experiment (TOPEX) mission. Prior to this, JASON and TOPEX were compared during our assessment of the TOPEX altimeter. With the end of the TOPEX mission, we developed methods to report on JASON as it related to GFO. It should be noted the GFO altimeter, after operating for over 7 years, was power cycled off to on and on to off approximately 14 times a day for over 18 months in space with no failure. The GFO altimeter proved to be a remarkable instrument providing stable ocean surface measurements for nearly eight years. This report completes our GFO altimeter performance assessment

Assessing Neuronal and Astrocyte Derived Exosomes From Individuals With Mild Traumatic Brain Injury for Markers of Neurodegeneration and Cytotoxic Activity.
Mild traumatic brain injury (mTBI) disproportionately affects military service members and is very difficult to diagnose. To-date, there is currently no blood-based, diagnostic biomarker for mTBI cases with persistent post concussive symptoms. To examine the potential of neuronally-derived (NDE) and astrocytic-derived (ADE) exosome cargo proteins as biomarkers of chronic mTBI in younger adults, we examined plasma exosomes from a prospective longitudinal study of combat-related risk and resilience, marine resiliency study II (MRSII). After return from a combat-deployment participants were interviewed to assess TBI exposure while on deployment. Plasma exosomes from military service members with mTBI (mean age, 21.7 years, n = 19, avg. days since injury 151), and age-matched, controls (deployed service members who did not endorse a deployment-related TBI or a pre-deployment history of TBI; mean age, 21.95 years, n = 20) were precipitated and enriched against a neuronal adhesion protein, L1-CAM, and an astrocyte marker, glutamine aspartate transporter (GLAST) using magnetic beads to immunocapture the proteins and subsequently selected by fluorescent activated cell sorting (FACS). Extracted protein cargo from NDE and ADE preparations were quantified for protein levels implicated in TBI neuropathology by standard ELISAs and on the ultra-sensitive single molecule assay (Simoa) platform. Plasma NDE and ADE levels of Aβ42 were significantly higher while plasma NDE and ADE levels of the postsynaptic protein, neurogranin (NRGN) were significantly lower in participants endorsing mTBI exposure compared to controls with no TBI history. Plasma NDE and ADE levels of Aβ40, total tau, and neurofilament light (NFL), P-T181-tau, P-S396-tau were either undetectable or not significantly different between the two groups. In an effort to understand the pathogenetic potential of NDE and ADE cargo proteins, neuron-like cultures were treated with NDE and ADE preparations from TBI and non-TBI groups. Lastly, we determined that plasma NDE but not ADE cargo proteins from mTBI samples were found to be toxic to neuron-like recipient cells in vitro. These data support the presence of markers of neurodegeneration in NDEs of mTBI and suggest that these NDEs can be used as tools to identify pathogenic mechanisms of TBI
Judging the impact of leadership-development activities on school practice
The nature and effectiveness of professional-development activities should be judged in a way that takes account of
both the achievement of intended outcomes and the unintended consequences that may result. Our research project set out to create a robust approach that school staff members could use to assess the impact of
professional-development programs on leadership and management practice without being constrained in this judgment by the stated aims of the program. In the process,
we identified a number of factors and requirements relevant to a wider audience than that concerned with the development of leadership and management in England.
Such an assessment has to rest upon a clear understanding of educational leadership,a clearly articulated model of practice, and a clear model of potential forms of impact.
Such foundations, suitably adapted to the subject being addressed, are appropriate for assessing all teacher professional development
