Solar wind data from the MIT plasma experiments on Pioneer 6 and Pioneer 7

Hourly averages are presented of solar wind proton parameters obtained from experiments on the Pioneer 6 and Pioneer 7 spacecraft during the period December 16, 1965 to August 1971. The number of data points available on a given day depends upon the spacecraft-earth distance, the telemetry bit rate, and the ground tracking time allotted to each spacecraft. Thus, the data obtained earlier in the life of each spacecraft are more complete. The solar wind parameters are given in the form of plots and listings. Trajectory information is also given along with a detailed description of the analysis procedures used to extract plasma parameters from the measured data

Equatorial Guinea Perspectives on the United States: the significance of American Missionary Activities and Internal Equatoguinean Politics (Expanded Version)

Equatorial Guinea is a small country in western Central Africa, consisting of three physically separate major territories and a number of tiny islands. The major territories are Rio Muni, which is on the continent sandwiched between Cameroon and Gabon, and the insular territories of Bioko (formally Fernando Po) in the Bight of Biafra and Annobon, which is about 357 kilometers off the coast and just south of the equator. The tiny islands are Corisco, Belobi, Mbane, Conga, Cocotiers, and Elobey, all located off the coast of Rio Muni. Equatorial Guinea is the only Spanish-speaking country in Africa. It gained independence from Spain on 12 October 1968. Since independence, the country's politics has been dominated by the Esangui clan, from the Mongomo district on the mainland. Equatorial Guinea is among Africa's top oil-producing nations and for that reason has become a major commercial partner of the United States. This small country, with just over a half-million people, is currently the fourth-largest recipient of U.S. foreign direct investment in sub-Saharan Africa, surpassed only by the much larger countries of Nigeria, South Africa, and Angola.National profile; Relations with the United States; From Mid 1800 to 1979; Relations during the Presidency of Francisco Macias Nguema; Relations after the Overthrow of the Macias Nguema Regime; Perspectives on the United States; Post-Macias Nguema Era; Popular culture; September 11; Outlook for the Coming Year

Radiolarian faunal characteristics in Oligocene of the Kerguelen Plateau, Leg 183, Site 1138

Three sites from Ocean Drilling Program (ODP) Leg 183 (Kerguelen Plateau) have been analyzed to document faunal change in high-latitude radiolarians and to compare the faunal change to Eocene-Oligocene climatic deterioration. Radiolarians are not preserved in Eocene sediments. In Oligocene sediments, radiolarian preservation improves in a stepwise manner toward the Miocene. A total of 115 species were found in lower Oligocene samples from Site 1138; all are documented herein. Radiolarian preservation is presumably linked to productivity triggered by climatic cooling during the early Oligocene. Similar patterns of improving preservation through the Eocene/Oligocene boundary are documented from several Deep Sea Drilling Project and ODP sites in the Southern Ocean, indicating a general pattern. In contrast to the Southern Kerguelen Plateau, however, proxies for productivity are more divergent at Site 1138 (Central Kerguelen Plateau). Whereas carbonate dissolution, as indicated by poor preservation of foraminifers and common hiatuses, is very pronounced in the upper Eocene-lowermost Oligocene, the quality of radiolarian and diatom preservation does not significantly increase until the uppermost lower Oligocene. Multiple measures of radiolarian diversity in the Oligocene from Site 1138 closely parallel radiolarian preservation, indicating that preserved radiolarian diversity is controlled by productivity

Stress appraisal, coping, and work engagement among police recruits: an exploratory study.

This study investigated the influence of stress appraisal and coping on work engagement levels (Absorption, Vigour, and Dedication) of police recruits. Participants were 387 men, ages 20 to 33 yr. (M = 24.1, SD = 2.4), in their last month of academy training before becoming police officers. Partially in support of predictions, work engagement was associated with Stressor control perceived, but not Stress intensity experienced over a self-selected stressor. Although the three dimensions of work engagement were explained by Stressor control and coping, Absorption was the dimension better explained by these variables. Police recruits reporting higher Absorption, Vigour, and Dedication reported using more Active coping and less Behavioural disengagement. Results showed that stress appraisal and coping are important variables influencing work engagement among police recruits. Findings suggested that future applied interventions fostering work engagement among police recruits should reinforce perceptions of control over a stressor as well as Active coping strategies

Life, Death, and IQ: It\u27s Much More than Just a Score: Understanding and Utilizing Forensic Psychological and Neuropsychological Evaluations in Atkins Intellectual Disability/Mental Retardation Cases

This article highlights best practices for assessing MR and ID in capital cases with an emphasis on Atkins trial preparation and potential problems the authors have noted through experience. These best practices in Atkins hearings concern issues for the lawyers, forensic psychologists, and neuropsychologists, which include: 1. Practice effects and IQ testing 2. Consistency of IQ scores over time 3. Flynn Effect 4. Malingering versus cognitive suboptimal effort 5. Lack of records indicating pre-age 18 diagnosis of MR/ID 6. Retrospective assessment of adaptive behaviors 7. Death row trends of increasing IQ over the years while incarcerated 8. Maladaptive behaviors versus symptoms of conduct disorder and antisocial personality disorder 9. There need be no nexus between an Atkins finding of mental retardation and the adaptive behavioral aspects of criminal and homicidal behavior 10. Potential bias of collateral informants 11. Cultural issues inherent in IQ and adaptive testing 12. Considering the utilization of different experts within a particular case, i.e., assessment of adaptive functioning versus assessment of intelligence 13. Videotaping assessments 14. Litigation strategies expanding MR/ID findings. Due to the length requirement of this article, some of these issues will be addressed and not to the extent of their respected complexities

Timing of a Young Mildly Recycled Pulsar with a Massive White Dwarf Companion

We report on timing observations of the recently discovered binary pulsar PSR J1952+2630 using the Arecibo Observatory. The mildly recycled 20.7-ms pulsar is in a 9.4-hr orbit with a massive, M_WD > 0.93 M_sun, white dwarf (WD) companion. We present, for the first time, a phase-coherent timing solution, with precise spin, astrometric, and Keplerian orbital parameters. This shows that the characteristic age of PSR J1952+2630 is 77 Myr, younger by one order of magnitude than any other recycled pulsar-massive WD system. We derive an upper limit on the true age of the system of 50 Myr. We investigate the formation of PSR J1952+2630 using detailed modelling of the mass-transfer process from a naked helium star on to the neutron star following a common-envelope phase (Case BB Roche-lobe overflow). From our modelling of the progenitor system, we constrain the accretion efficiency of the neutron star, which suggests a value between 100 and 300% of the Eddington accretion limit. We present numerical models of the chemical structure of a possible oxygen-neon-magnesium WD companion. Furthermore, we calculate the past and the future spin evolution of PSR J1952+2630, until the system merges in about 3.4 Gyr due to gravitational wave emission. Although we detect no relativistic effects in our timing analysis we show that several such effects will become measurable with continued observations over the next 10 years; thus PSR J1952+2630 has potential as a testbed for gravitational theories.Comment: 12 pages, 10 figures, to be published in MNRA
