Fundamental properties of the planet Venus, such as its internal mass distribution and variations in length of day, have remained unknown. We used Earth-based observations of radar speckles tied to the rotation of Venus obtained in 2006-2020 to measure its spin axis orientation, spin precession rate, moment of inertia, and length-of-day variations. Venus is tilted by 2.6392 $\pm$ 0.0008 degrees ($1\sigma$) with respect to its orbital plane. The spin axis precesses at a rate of 44.58 $\pm$ 3.3 arcseconds per year ($1\sigma$), which gives a normalized moment of inertia of 0.337 $\pm$ 0.024 and yields a rough estimate of the size of the core. The average sidereal day on Venus in the 2006-2020 interval is 243.0226 $\pm$ 0.0013 Earth days ($1\sigma$). The spin period of the solid planet exhibits variations of 61 ppm ($\sim$20 minutes) with a possible diurnal or semidiurnal forcing. The length-of-day variations imply that changes in atmospheric angular momentum of at least $\sim$4% are transferred to the solid planet.

The CCAT-prime telescope is a 6-meter aperture, crossed-Dragone telescope, designed for millimeter and sub-millimeter wavelength observations. It will be located at an altitude of 5600 meters, just below the summit of Cerro Chajnantor in the high Atacama region of Chile. The telescope's unobscured optics deliver a field of view of almost 8 degrees over a large, flat focal plane, enabling it to accommodate current and future instrumentation fielding >100k diffraction-limited beams for wavelengths less than a millimeter. The mount is a novel design with the aluminum-tiled mirrors nested inside the telescope structure. The elevation housing has an integrated shutter that can enclose the mirrors, protecting them from inclement weather. The telescope is designed to co-host multiple instruments over its nominal 15 year lifetime. It will be operated remotely, requiring minimum maintenance and on-site activities due to the harsh working conditions on the mountain. The design utilizes nickel-iron alloy (Invar) and carbon-fiber-reinforced polymer (CFRP) materials in the mirror support structure, achieving a relatively temperature-insensitive mount. We discuss requirements, specifications, critical design elements, and the expected performance of the CCAT-prime telescope. The telescope is being built by CCAT Observatory, Inc., a corporation formed by an international partnership of universities.

A strategy for including writing of a research paper in a university's advanced intensive English course for students of English as a second language is described. The method consists of eight assignments given over the course of 11 weeks, resulting in a short research paper. The method is designed to minimize error by dealing with specific problems as the students progress through the process. It uses a conference-based, step-by-step approach to assignments and assessment, focuses on writing as a process, and ensures that the paper is original. A detailed weekly schedule of assignments provided as a reference for students, and teacher notes on and discussion of the eight specific assignments, are outlined. The assignments include: (1) preliminary topic selection and library tour; (2) a library sources search and final topic selection; (3) a thesis statement and sources search; (4) a preliminary outline and sources search; (5) a sentence outline and sources search; (6) note card development; (7) a first draft; and (8) a final draft. A list of actual topics and thesis statements and a sample student outline are appended. (MSE)

This dissertation examines four texts drawn from the realist and modernist periods, contemporaneous in many respects with the crucial shifts generally recognized as constitutive of consumer culture. It explores some of the dominant literary figurations of these shifts, and how, even as many authors derided this new consumer-oriented urban landscape and what was frequently characterized as its manipulative use of idealized images in marketing and advertising, literary production in this era borrowed in a variety of ways from this new spectacular cultural logic in its own creations. More specifically, these chapters explore how conceptualizations of race, gender and class were influenced by new forms of mass production and advertising that coded its products according to a similarly stratified logic. In so doing they focus particularly on issues of specularity in the literature, advertising and popular media of the day, clarifying the sociological landscape of literary that modernism represented a crucial pivot point between high capitalism and its forms of identity based on one's relationship to the system of production, to our present era in which identity is understood to be something grounded more in one's patterns of consumption, and their relationship to our increasingly image-based culture and its investment in "virtual community," as recent phenomena such as You Tube and social networking sites like Facebook and Second Life demonstrate

We present thermal properties and an improved shape model for potentially hazardous asteroid (162421) 2000 ET70. In addition to the radar data from 2000 ET70's apparition in 2012, our model incorporates optical lightcurves and infrared spectra that were not included in the analysis of Naidu et al. (2013, Icarus 226, 323-335). We confirm the general "clenched fist" appearance of the Naidu et al. model, but compared to their model, our best-fit model is about 10% longer along its long principal axis, nearly identical along the intermediate axis, and about 25% shorter along the short axis. We find the asteroid's dimensions to be 2.9 km $\times$ 2.2 km $\times$ 1.5 km (with relative uncertainties of about 10%, 15%, and 25%, respectively). With the available data, 2000 ET70's period and pole position are degenerate with each other. The radar and lightcurve data together constrain the pole direction to fall along an arc that is about twenty-three degrees long and eight degrees wide. Infrared spectra from the NASA InfraRed Telescope Facility (IRTF) provide an additional constraint on the pole. Thermophysical modeling, using our SHERMAN software, shows that only a subset of the pole directions, about twelve degrees of that arc, are compatible with the infrared data. Using all of the available data, we find that 2000 ET70 has a sidereal rotation period of 8.944 hours ($\pm$ 0.009 h) and a north pole direction of ecliptic coordinates $(52^{\circ}, -60^{\circ}) \pm 6^{\circ}$. The infrared data, acquired over several dates, require that the thermal properties (albedo, thermal inertia, surface roughness) must change across the asteroid's surface. By incorporating the detailed shape model and spin state into our thermal modeling, the multiple ground-based observations at different viewing geometries have allowed us to constrain the levels of the variations in the surface properties., Comment: Revised and submitted to Icarus; 22 pages, 13 figures; 51 supplementary figures (in a 25MB PDF) can be found at http://astro.cornell.edu/~seanm/2000et70

BACKGROUND: Hospital admissions for heart failure are predicted to rise substantially over the next decade placing increasing pressure on the health care system. There is an urgent need to redesign systems of care for heart failure to improve evidence-based practice and create seamless transitions through the continuum of care. The aim of the review was to examine systems of care for heart failure that reduce hospital readmissions and/or mortality. METHOD: Electronic databases searched were: Ovid MEDLINE, EMBASE, CINAHL, grey literature, reviewed bibliographies and Cochrane Central Register of Controlled Trials for randomised controlled trials, non-randomised trials and cohort studies from 1(st) January 2008 to 4(th) August 2015. Inclusion criteria for studies were: English language, randomised controlled trials, non-randomised trials and cohort studies of systems of care for patients diagnosed with heart failure and aimed at reducing hospital readmissions and/or mortality. Three reviewer authors independently assessed articles for eligibility based on title and abstract and then full-text. Quality of evidence was assessed using Newcastle-Ottawa Scale for non-randomised trials and GRADE rating tool for randomised controlled trials. RESULTS: We included 29 articles reporting on systems of care in the workforce, primary care, in-hospital, transitional care, outpatients and telemonitoring. Several studies found that access to a specialist heart failure team/service reduced hospital readmissions and mortality. In primary care, a collaborative model of care where the primary physician shared the care with a cardiologist, improved patient outcomes compared to a primary physician only. During hospitalisation, quality improvement programs improved the quality of inpatient care resulting in reduced hospital readmissions and mortality. In the transitional care phase, heart failure programs, nurse-led clinics, and early outpatient follow-up reduced hosp

Background: Globally there are few reports of the impairments, disabilities and medications used in people living with idiopathic Parkinson’s disease. Caregiver characteristics and caregiver burden have seldom been reported. We examined the health status in a large cohort of people living with Parkinson’s disease and their caregivers managed in a comprehensive health care setting. Methods/Design: A prospective, cross sectional analysis of impairments, disabilities and Parkinson’s disease medication use was conducted in a sample of 100 people with Parkinson’s disease rated I-IV on the modified Hoehn & Yahr scale. Participants were recruited from the Victorian Comprehensive Parkinson Program in Melbourne, Australia. Their caregivers were invited to provide their views on the burden of care, services provided and support received. Results: The severity of impairments and disabilities was strongly associated with disease duration (mean of 5.5 years). Those with long standing disease or more severe disease also used more Parkinson’s disease medications and participated in fewer social roles than people who were newly diagnosed or mildly affected. The severity of impairments was strongly correlated with limitations in performing activities of daily living. Limitations in performing daily activities were also found to be a significant contributing factor for health-related quality of life (PDQ-39 SI β=0.55, p=0.000; EQ-5D SI β=0.43, p=0.001). People with Parkinson’s disease lived at home with relatives. The average caregiver was a spouse or child providing approximately 3.5 hours of care per day, with the capacity to provide 9.4 hours per day and had provided care for four years. Additional support was high (63%) for 2.5 hours per day. Conclusion: The comprehensive care setting of this cohort describes a relatively benign condition despite a wide range of disease duration and severity. Th

CIVINS (Civilian Institutions) Thesis document, The purpose of this paper was to conduct an in-depth analysis of total cost, quality, and response times using in-house (government civil service) or contracted (private) work forces to complete facilities maintenance work and recommend the best method of performance of these functions at a Navy Public Works Center. Actual work force structure, total cost, quality and response time data was analyzed for Navy Public Works Center Pensacola, which uses in-house work forces, and Navy Public Works Center Jacksonville, which uses contracted work forces, to determine the value received by their customers. The data was analyzed on a macro- level to compare total revenue to direct and direct plus overhead personnel to determine the amount of direct work produced per employee at both locations. A more in-depth analysis was then conducted on the types of maintenance work the Public Works Centers provide, Emergency Service work, Recurring work, and Minority Specific work orders, to determine which location provides the best value to their customers. The results of the analysis showed that for all types of maintenance work in- house work forces provided comparable if not better value to their customers than contracted work forces. This service was delivered with roughly the same response time and usually at the same or lower cost. Additionally, because of the projected rate increases at PWC Jacksonville the value PWC Pensacola's customers receive will be even greater for the next several years, http://archive.org/details/inhousevscontrac109458533, CIVINS

BACKGROUND: Mindfulness-based stress reduction (MBSR) programs have consistently been shown to enhance the psychosocial well-being of participants. Given the well-established association between psychosocial factors and immunologic functioning, it has been hypothesized that enhanced psychosocial well-being among MBSR participants would be associated with corresponding changes in markers of immune activity. OBJECTIVES: The objectives of this study were to examine changes in psychosocial and immunologic measures in a heterogeneous patient sample following participation in a MBSR program. DESIGN: A single-group, pretest/post-test design was utilized. SETTING: The intervention was conducted at an academic health center. SUBJECTS: This pilot study involved 24 participants (aged 28-72 years). Inclusion criteria were as follows: > or =18 years of age, English-speaking, and no known autoimmune disorder. INTERVENTION: The intervention was an 8-week MBSR program. OUTCOME MEASURES: Distress and quality of life (QOL) measures included the Brief Symptom Inventory-18 and the Medical Outcomes Survey Short-Form Health Survey, respectively. Immunologic measures included natural killer (NK) cell cytolytic activity and C-reactive protein (CRP). RESULTS: Patients completed psychosocial assessments and provided a blood sample at baseline (pre-MBSR) and within 2 weeks post-MBSR. Significant improvements in anxiety and overall distress as well as across multiple domains of QOL were observed from baseline to post-MBSR. Reductions in anxiety and overall distress were associated with reductions in CRP. Patients who reported improvement in overall mental well-being also showed increased NK cytolytic activity from pre- to post-MBSR, whereas patients who reported no improvement in mental well-being showed no change in NK cytolytic activity. CONCLUSIONS: Positive improvement in psychologic well-being following MBSR was associated with increased NK cytolytic activity and decreased levels of CRP.

This study describes the epidemiology of community-acquired pneumonia (CAP) in elderly Australians for the first time. Using a case-cohort design, cases with CAP were in-patients aged > or = 65 years with ICD-10-AM codes J10-J18 admitted over 2 years to two tertiary hospitals. The cohort sample was randomly selected from all hospital discharges, frequency-matched to cases by month. Logistic regression was used to estimate risk ratios for factors predicting CAP or associated mortality. A total of 4772 in-patients were studied. There were 1952 cases with CAP that represented 4% of all elderly admissions: mean length of stay was 9.0 days and 30-day mortality was 18%. Excluding chest radiograph, 520/1864 (28%) cases had no investigations performed. The strongest predictors of CAP were previous pneumonia, history of other respiratory disease, and aspiration. Intensive-care-unit admission, renal disease and increasing age were the strongest predictors of mortality, while influenza vaccination conferred protection. Hospitalization with CAP in the elderly is common, frequently fatal and a considerable burden to the Australian community. Investigation is ad hoc and management empirical. Influenza vaccination is associated with reduced mortality. Patient characteristics can predict risk of CAP and subsequent mortality.

Background Despite the finding that Parkinson disease (PD) occurs in more than one in every 1000 people older than 60 years, there have been few attempts to quantify how deficits in impairments, activity, participation, and quality of life progress in this debilitating condition. It is unclear which tools are most appropriate for measuring change over time in PD. Methods and design This protocol describes a prospective analysis of changes in impairments, activity, participation, and quality of life over a 12 month period together with an economic analysis of costs associated with PD. One-hundred participants will be included, provided they have idiopathic PD rated I-IV on the modified Hoehn & Yahr (1967) scale and fulfil the inclusion criteria. The study aims to determine which clinical and economic measures best quantify the natural history and progression of PD in a sample of people receiving services from the Victorian Comprehensive Parkinson's Program, Australia. When the data become available, the results will be expressed as baseline scores and changes over 3 months and 12 months for impairment, activity, participation, and quality of life together with a cost analysis. Discussion This study has the potential to identify baseline characteristics of PD for different Hoehn & Yahr stages, to determine the influence of disease duration on performance, and to calculate the costs associated with idiopathic PD. Valid clinical and economic measures for quantifying the natural history and progression of PD will also be identified.

This study examines the validity of using ICD-10 codes to identify hospitalized pneumonia cases. Using a case-cohort design, subjects were randomly selected from monthly cohorts of patients aged 65 years discharged from April 2000 to March 2002 from two large tertiary Australian hospitals. Cases had ICD-10-AM codes J10–J18 (pneumonia); the cohort sample was randomly selected from all discharges, frequency matched to cases by month. Codes were validated against three comparators: medical record notation of pneumonia, chest radiograph (CXR) report and both. Notation of pneumonia was determined for 5098/5101 eligible patients, and CXR reports reviewed for 3349/3464 (97%) patients with a CXR. Coding performed best against notation of pneumonia: kappa 0·95, sensitivity 97·8% (95% CI 97·1–98·3), specificity 96·9% (95% CI 96·2–97·5), positive predictive value (PPV) 96·2% (95% CI 95·4–97·0) and negative predictive value (NPV) 98·2% (95% CI 97·6–98·6). When medical record notation of pneumonia is used as the standard, ICD-10 codes are a valid method for retrospective ascertainment of hospitalized pneumonia cases and appear superior to use of complexes of symptoms and signs, or radiology reports.

Use of self-reported vaccination status is commonplace in assessing vaccination coverage for public health programs and individuals, yet limited validity data exist. We compared self-report with provider records for pneumococcal (23vPPV) and influenza vaccine for 4887 subjects aged ≥65 years from two Australian hospitals. Self-reported influenza vaccination status had high sensitivity (98%), positive predictive value (PPV) (88%) and negative predictive value (NPV) (91%), but low specificity (56%). Self-reported 23vPPV (previous 5 years) had a sensitivity of 84%, specificity 77%, PPV 85% and NPV 76%. Clinicians can be reasonably confident of self-reported influenza vaccine status, and for positive self-report for 23vPPV in this setting. For program evaluation, self-reported influenza vaccination coverage among inpatients overestimates true coverage by about 10% versus 1% for 23vPPV. Self-report remains imperfect and whole-of-life immunisation registers a preferable goal.

This study examines missed opportunities for recommended influenza vaccine and 23-valent pneumococcal vaccine (23vPPV) among hospitalised elderly persons. 4772 inpatients aged ≥65 years (cases of pneumonia and frequency-matched randomly selected cohort subjects) participated from two large tertiary Australian hospitals. For subjects unvaccinated with influenza vaccine (past year), 1110/1115 (99.6%) had visited either a doctor (99.4%, mean 11.2 visits) or the same hospital (52.0%, mean 1.5 visits). For those unvaccinated with 23vPPV (past 5 years), 1809/1813 (99.8%) had visited either a doctor (99.7%, mean 11.2 visits) or the same hospital (51.5%, mean 1.5 times) in the past year; 71% had been admitted to the same hospital in the past 5 years (mean 3.4 times). 2.3% of all subjects had vaccination status recorded. No unvaccinated subject was vaccinated during admission, despite approximately 40% reporting acceptability of vaccination if offered. Previous hospitalisation was a risk factor for being unvaccinated. Barriers to implementation of current vaccination policy in the hospital setting require formal evaluation in Australia.

The National Museum of the Pacific War presents an interview with Donald L. Campbell. Campbell joined the Navy in August 1943, at the age of eighteen. He completed gunnery school in Gulf Port, Mississippi and served as an Armed Guard aboard Merchant Marine ships. In February 1944, he was transported to Fremantle, Australia. Campbell shares his experiences getting initiated upon crossing the equator, and transporting supplies of ammunition, bombs, planes and Army trucks to Calcutta, India. He notes going through the Suez Canal in their travels to New York. In August 1944, he was assigned to SS Ralph W. Emerson, and traveled to Scotland and unloaded food and ammunition supplies to Omaha Beach in September. In December, they traveled through the Panama Canal on their way to deliver supplies to Manus Island and Bougainville and landed in Manila by the end of May 1945. He continued his service after the war ended, receiving his discharge in March 1946.

Arecibo S-band (lambda=13cm) radar observations of Comet C/2001 A2 (LINEAR) on 2001 July 7-9 showed a strong echo from large coma grains. This echo was significantly depolarized. This is the first firm detection of depolarization in a grain-coma radar echo and indicates that the largest grains are at least lambda / 2 or 2 cm in radius. The grains are moving at tens of m/s with respect to the nucleus. The non-detection of the nucleus places an upper limit of 3 km on its diameter. The broad, asymmetric echo power spectrum suggests a fan of grains that have a steep (differential number ~ a^-4) size distribution at cm-scales, though the observed fragmentation of this comet complicates that picture., Comment: 20 pages, 3 tables, 5 figures Submitted to Icarus

The influence of individual differences and task variables on variance in perceived task attributes was explored in the controlled setting of an assessment center. One-hundred twenty-seven state civil servants who were participants in an assessment center run by the state rated the importance for successful performance of eight task attributes in each of four exercises. The results showed systematic differences in the attributes perceived to be important for success on the task. The differences were a function of the tasks and of the individuals. Further analyses showed that individuals clustered on the basis of the similarity of their task perceptions also performed differently. In addition, the proportion of their performance variance associated with motivation as defined by Expectancy theory also varied according to group membership based upon similar perceptions.

The role perceptions of fifty-eight engineers in a medium size industrial organization were related to their performance, job satisfaction, and affective responses to their role. The first concept of interest was role compliance--the extent to which the engineers described their own role behavior in line with what their supervisory or their peers believed should be done. Role compliance was found to influence job satisfaction and affective responses to the job directly and to moderate the relationship between motivational force, as described by Expectancy Theory, and performance or effort. The second concept of interest was the degree to which the role possessed motivational potential as described by Hackman and Oldham (1974). The results indicated that the motivational potential of the task impacted both directly and indirectly on job satisfaction and affective responses to the job, but only indirectly on performance. The results were discussed in light of the need for accurate communication of role requirements and the effects of expanding the motivational potential of a job.

Perceptions of instrumentalities and expectancies used to index work motivation in Expectancy theory were investigated in a sample of 58 engineers in a manufacturing organization. Instrumentalities and expectancies of focal engineers were compared to those of their supervisor and two sets of peers nominated by the focal engineer. The results showed that the focal engineers' perceptions of the rewards associated with performance agreed closely with those of chosen peers. However, for supervisors, the agreement was high for new engineers but diverged from the supervisors as the focals gained more experience on the job. The implications of this and other findings were discussed in light of their effects on supervisory and organizational attempts to influence performance through motivation.

The introduction briefly describes the importance of the Air Force Logistics Command's Depot Maintenance program and details the author's road map in discussing the research topic. An analysis of Project Overlook, a 1982 AFLC directed review of the Quality Assurance program follows. Current quality assurance guidance for AFLC is reviewed from command level to the production planning level. A major portion of any quality assurance program, customer feedback, is then discussed. The Quality Deficiency Reporting System is used by AFLC for this purpose. The author then briefly discusses some quality assurance programs from the Army depots, Navy Aviation depots, and the status of quality assurance in civilian industries. A discussion of the statistical process control program as espoused by Dr. W. Edward Deming and some of his management principles that could be used by AFLC follows. Finally, the author provides three recommendations for improving the AFLC Quality Assurance program.

Models have been developed for evaluating chemical devices in the one-on-one and barricade-and-hostage types of law-enforcement scenarios. Thus, with the model developed under an earlier task for evaluatiing chemical devices in the crowd control-type scenario, models have now been developed for evaluating chemical devices in the three general types of law enforcement type-situations deemed amenable to the effective employment of chemical incapacitating agents. The quantitative measures obtained for selected devices, tested under another task, have been used in these models to obtain estimates of sample performance levels of these devices when employed in applicable scenarios.

The report presents an analysis of measured physiological effects resulting from impacts of several different types of allegedly less lethal projectiles. The analysis gives indications as to which projectile characteristics tend to correlate most highly with damage and which critical parts of the body are most susceptible to damage/undesirable effect from the various projectiles. In addition, some preliminary findings are given as to what characteristics tend to optimize a 'kinetic-energy' dispersal weapon.

Gunner aiming data are presented when engaging two kinds of main battle tank targets-the M60A1 and the Swedish Casemate which ostensibly present the engaging gunner with targets of significantly different shape and size. The data are analyzed in terms of target size and shape as a function of selection of (selected versus forced) firing positions. Implications of the effects of tank design and presented target area on the performance of engaging enemy gunners are drawn. (Author)

This work was undertaken to establish the feasibility of using ozone to lower the elemental phosphorus level of phosphorus contaminated water at Edgewood Arsenal. Separate samples of this phossy water were treated with ozone at various mass rates in a sparged stirred reactor. The ozone repeatedly reduced the elemental phosphorus concentration below the limits of detection. Simple aeration also oxidized the white phosphorus but not at the rate nor to the extent that ozone showed. No correlation could be developed between elemental phosphorus lowering and its extent of conversion to the phosphate form. A white precipitate comprised mainly of calcium phosphate formed as the phossy water was oxidized. Thus, preliminary data resulted which prove the feasibility of using ozone to treat phossy water and which will lead the way for further studies in this area.

A facility has been developed for testing and evaluating thermal imaging sensors. The facility employs a differential temperature source imaged by a 12 inch off-axis parabolic mirror collimator. The facility can provide differential temperatures ranging from -20C to +80C. Four-bar resolution targets are available from 0.25 cy/mrad to 9.0 cy/mrad. Tests that can be performed include minimum resolvable temperature difference (MRT), signal transfer function (SiTF), modulation transfer function (MTF) and line spread function (LSF), uniformity, and distortion.

The chemical hexamine, from the Ammonia Recovery Area of Holston Army Ammunition Plant, is presently being released into the Holston River. This study provides a means to recover the hexamine in a concentrated stream anywhere between fifteen and thirty weight percent. In this way, contaminant and hydraulic loads are reduced before entering the proposed treatment facilities. A computer simulation was used to design and prove the feasibility of the resulting two distillation columns. Several cost savings should result from these calculations. (Author)

Geotechnical surveys have been recently completed in the North Boundary Vicinity of Rocky Mountain Arsenal to define the arsenal's subsurface hydrogeology. Water table measurements and permeability estimates have been generated to refine flow direction and quantify ground water movement of the alluvial aquifer as it flows across the North Boundary. This document presents a compilation of data assessments based upon the aforementioned survey results on expected fluoride contaminant loading with the proposed expanded North Boundary control system. As a result of these assessments, it has been determined that there is a good possibility that fluoride levels within the expanded treatment subsystem will be naturally below the state of Colorado limit, this may negate the need to add a costly fluoride removal module to the proposed granular carbon organic removal process. -BKA

The development of current evaluative investigation tends to acknowledge, theoretically, the necessity of a synthesis between quantitative and qualitative perspective. In this article the author leaves the strong quantitative position that he maintained in previous works, presenting now the qualitative perspective as a necessary complement to the quantitative one. Qualitative methodology of cases study within the social science framework is analysed, the possible problems and its advantages. Some suggestions in order to improve the cases study, its validity and interpretation are as well presented., El desarrollo de la investigación evaluativa en la actualidad tiende a reconocer, teóricamente, la necesidad de una síntesis entre la perspectiva cuantitativa y la cualitativa. En este artículo se abandona la posición cuantitativa fuerte, mantenida por este autor en trabajos anteriores, para presentar ahora la perspectiva cualitativa como complemento necesario de la cuantitativa. Se analiza la metodología cualitativa del estudio de casos dentro del ámbito de la ciencia social y los posibles problemas que se plantean, así como, sus ventajas. También se observan una serie de sugerencias con el fin de mejorar el estudio de casos, en su validez y en su interpretación.

This report attempts to provide a systematic analysis of some types of civil disturbances and a survey of related developmental materiel. The major limitation of the analysis is its restriction to ghetto - type riots, necessitated by limitations in time and available information. However, the materiel items described are universal in application to various forms of civil disturbances. The first part of the report analyzes such riots by identifying common characteristics of a number of disturbances which have occurred in the United States and describing the experiences of various security forces in their control. The latter part of the report serves as a catalog of materiel items, not already in the Army inventory, which may be useful in providing a more flexible response to the special requirements of riot control.

Slide rules have been contrived for evaluating O. G. Sutton's mathematical models for estimating the downwind travel and area coverage from an instantaneous point source of vapor or very fine aerosol disseminated and sampled at ground level. Using these slide rules, the nonmathematician can employ the mathematical theory for making preliminary weapons-effects predictions necessary in handling everyday problems encountered in research and development of chemical-weapons systems.

A series of He Tests was planned at the Nevada Test Site preparatory to the nuclear explosions in Operation JANGLE. These HE shots were designed to obtain, under similar conditions, data to be used as a basis for making predictions concerning the phenomena to be studied during the nuclear explosions. The HE program, as originally conceived, was expanded to permit further study of the base surge and crater phenomena. Ten HE shots (a total of thirteen explosions) were conducted in the upper Yucca Flat and Frenchman Flat areas. Practically all of the instrumentation by the various participating agencies was done on the first series (HE-1 through HE-4). With a few minor exceptions, all instrumentation performed in a satisfactory manner. Shot HE-2 consisting of 40,000 pounds of TNT was fired with the c. g. 4.63 feet below the surface. There was a high order of detonation and the shot was completely successful., Report on Operation Jangle, Project 1(9) - 3.

To gain an understanding of the relationship of drug detector sensitivity to the actual detection of drug abusers, those parameters which are considered of prime importance in determining the probability of detecting drug abusers were examined. In addition, attempts were made to quantify the important relations of drug concentration in urine to elapsed time after drug administration and elapsed time after urination.

The Comprehensive Law and Order Assistance Research and Development (CLOARAD) Program was concerned with hardware and tactics of potential value to military forces assigned to help control civil disturbances. The Program was a small-scale attempt to evaluate specific tactical problems and requirements imposed on military forces in disturbances. Within the restrictions of scarce data and time, manpower and funding limitations, the report delineates the most important problems identified during the Program and presents guidelines for the solution of these problems. Two firm recommendations are made in the report: there should be comprehensive systems analyses to determine the best feasible solutions for the problems stated in the report; and there should be a larger- scale, intensive effort to assemble and analyze pre-defined data on civil disturbances.
