The presence, percentage, origins, and rate of formation of clay minerals have been important components in studies involving the geochemical and structural composition of waste-rock piles. The objective of the present study was to investigate the use of tritium as an indicator of the origin of clay minerals within such piles. Tritium values in pore water, interlayer water, and structural hydroxyl sites of clay minerals were examined to evaluate the origins of clay minerals within waste-rock piles located near Questa, New Mexico. Five clay minerals were identified: kaolinite, chlorite, illite, smectite, and mixedlayer illite-smectite, along with the hydrous sulfate minerals gypsum and jarosite. Analysis of waters derived from clay minerals was achieved by thermal reaction of dry-sieved bulk material obtained from the Questa site. In all Questa samples, the low-temperature water derived from pore-water and interlayer sites, as well as the intermediate-temperature water derived from interlayer cation sites occupied by hydronium and structural hydroxyl ions, show tritium values at or near modern levels for precipitation. Pore water and interlayer water ranged from 5.31 to 12.19 tritium units (TU) and interlayer hydronium and structurally derived water ranged from 3.92 to 7.93 TU. Tritium levels for local precipitation ranged from ~4 to 8 TU. One tritium unit (TU) represents one molecule of 3H1HO in 1018 molecules of 1H1HO. The elevated levels of tritium in structural sites can be accounted for by thermal incorporation of significant amounts of hydronium ions in interlayer cation sites for illite and mixed-layer clays, both common at the Questa site. In low-pH environments, such as those found within Questa waste-rock piles (typically pH ~3), the hydronium ion is an abundant species in the rock-pile pore-water system.

Background: The FIRST Trial is a 5-year study funded by the Agency for Healthcare Research and Quality. Our investigation is situated within a more extensive study to restrict fluoroquinolone antibiotics by requiring providers to obtain authorization from an infectious disease physician before prescribing fluoroquinolones. Our research team is performing a systematic evaluation to identify organizational characteristics and influencers of the fluoroquinolone preprescription authorization implementation process to understand variables that may facilitate or hinder implementation success. Methods: To address this critical gap, we present a qualitative analysis from our ongoing, multisite research project aimed at systematically assessing the adoption of an antimicrobial stewardship intervention in the form of an EHR-integrated best-practice alert (BPA) at each site to identify work system factors that impact uptake and variability in the implementation of the BPA at each location. The evaluation provides a detailed explanation of activities through the implementation process (eg, before implementation, during implementation, and after implementation) to assess how an organization effectively negotiates the phases and transitions, ultimately influencing the impact of the intervention. We have used a contextual determinant framework (CFIR) that has enabled us to perform a systematic and comprehensive exploration and identification of potential explanatory themes or variables to shed light on the complex social phenomenon of implementation. Results: Participants who will be a part of our poster presentation will learn about implementing a BPA, the potential barriers to implementation, and strategies for overcoming these barriers. Stakeholders within our study include site coordinators, medical doctors, nurses, pharmacists, and clinical informaticists. Our analysis synthesizes their experiences implementing and sustaining this evidence-based antimicrobial stewardship intervention. It includes (1) a detailed description of the process of change, (2) work-system factors (eg, inner setting and outer setting) that they believe influenced the success of the intervention, (3) barriers and facilitators (eg, CFIR constructs) within the implementation process; and (4) description of how these could have influenced the outcomes of interest (eg, implementation and intervention effectiveness). Conclusions: Our research is expected to advance patient safety research and initiatives by providing a more robust approach to performing systematic intervention evaluations. By outlining stakeholders’ experiences within our study, implementation leaders within healthcare systems will utilize our findings to aid them in their design and implementation process when designing and implementing similar types of healthcare interventions.

Summary
Well-designed markets and public-sector actions can promote climate-resilient agriculture and improve livelihood opportunities for farmers. To enable small-scale farmers to access appropriate technologies, agronomic services, and markets while fostering rural industrialisation, countries in Asia, Latin America, and Africa have created geographically focused, transformative commodity value-chain clusters. In addition, novel initiatives to incentivise the adoption of sustainable practices have demonstrated potential to contribute to food-system transformation. For example, private-sector co-investments with small and medium-sized enterprises and farmer cooperatives aim to accelerate financial inclusion and scale climate-resilient agriculture. National policy adoption of low-emissions practices, such as alternate wetting and drying, supports innovations in rice systems. Together, the public sector and privately driven initiatives can build markets that are advantageous for small-scale farmers and lessen their risks.

This article examines British Protestant missionary scholars' representations of Tamil culture and history, analysing how this form of knowledge evolved in relation to missionary concerns and the intellectual trends of nineteenth-century India. I focus on the work of Robert Caldwell, whose scholarship had a profound influence on the identity discourses of twentieth-century Tamil nationalism. I situate Caldwell's work in ethnography and philology within the broader field of colonial knowledge produced about Tamils in nineteenth-century India and within a broader study of British missionary concerns in South India. I examine two of Caldwell's publications to argue that his later work, far from being driven by mere scholarly interests, was also shaped by his concerns as a missionary, and that his evolving scholarship mirrored the development of anti-Brahmanism in British Protestant missionary circles of the time. Missionary anti-Brahmanism arose as a response to the caste system, which missionary groups came to regard as the biggest obstacle to Christian conversions. Departing from some of his earlier ideas, Caldwell strategically positioned his later work to challenge Brahman influence, which he saw as being intrinsically tied to the strength of caste sentiment in Indian society. Caldwell's construction of a discursive framework for understanding Tamil linguistic identity was informed by public reactions to his first publication and his subsequent understanding of the dynamic relationship between European scholarship and Indian social relations. More broadly, this article demonstrates the close relationships between Protestant Christian missionary activity, Indian social politics, and the field of knowledge production in colonial South India.

To tackle the problem of soil erosion and moisture stress, the government of Ethiopia introduced a yearly mass campaign where communities get together and implement various soil and water conservation (SWC) and water harvesting (WH) practices. Although the interventions are believed to have reduced soil erosion/sediment yield and enhanced surface and ground water, quantitative information on the impacts of various options at different scales is scarce. The objective of this study was to assess the impacts different land uses, SWC and WH interventions on water and suspended sediment yield (SSY) at plot and watershed scales in the central highlands of Ethiopia. Standard erosion plot experiments and hydrological stations were used to monitor the daily water and SSY during 2014 to 2017. The results show differences between treatments both at plot and watershed scales. Runoff and soil loss were reduced by an average 27 and 37%, respectively due to SWC practices at the plot level. Overall, SWC practices implemented at the watershed level reduced sediment yield by about 74% (in the year 2014), although the magnitude of sediment reduction due to the SWC interventions reduced over time. At both scales it was observed that as the number of years since SWC measures have been in place increased, their effectiveness declined due to the lack of maintenance. This study also revealed that extrapolating of plot data to watershed scale causes over or under estimation of net erosion.

Field experiments were conducted in Oklahoma to determine the effects of row spacing, cultivar, seeding rate, and water or ammonium polyphosphate fertilizer injection in the row at seeding, on the competitiveness of hard red winter wheat with cheat. Decreasing row spacing from 23 to 8 cm increased yield of weed-free wheat at two of three locations and cheat-infested wheat in six of ten experiments. Increasing seeding rate from 265 to 530 seeds m-2 increased wheat yield. Injecting water at 20 ml m-1 of row at seeding did not increase wheat emergence or yield. Cheat seed production was not consistently suppressed by any one cultivar. Juvenile growth habit was unrelated to wheat competitiveness.

Field experiments were conducted in Oklahoma to determine the effects of winter wheat seeding date and cheat infestation level on cultural cheat control obtained by increasing winter wheat seeding rates and decreasing row spacing. Seeding rate and row spacing interactions influenced cheat density, biomass, or seed in harvested wheat (dockage) at two of three locations. Suppressive effects on cheat of increasing wheat seeding rates and reduced row spacings were greater in wheat seeded in September than later. At two other locations, increasing seeding rate from 67 to 101 kg ha–1 or reducing row spacings from 22.5 to 15 cm increased winter wheat yield over a range of cheat infestation levels.

Background
It is well established that the presence of prominent anxiety within depressive episodes portends poorer outcomes. Important questions remain as to which anxiety features are important to outcome and how sustained their prognostic effects are over time.
AimsTo examine the relative prognostic importance of specific anxiety features and to determine whether their effects persist over decades and apply to both unipolar and bipolar conditions.
MethodParticipants with unipolar (n = 476) or bipolar (n = 335) depressive disorders were intensively followed for a mean of 16.7 years (s.d. = 8.5).
ResultsThe number and severity of anxiety symptoms, but not the presence of pre-existing anxiety disorders, showed a robust and continuous relationship to the subsequent time spent in depressive episodes in both unipolar and bipolar depressive disorder. The strength of this relationship changed little over five successive 5-year periods.
ConclusionsThe severity of current anxiety symptoms within depressive episodes correlates strongly with the persistence of subsequent depressive symptoms and this relationship is stable over decades.

In three collaborating institutions 105 hospitalized female anorexia nervosa patients were assessed for depressive symptomatology periodically during treatment. As a whole, patients were mildly to moderately depressed, being as depressed as anxious neurotics and less depressed than depressed neurotics. The more depressed patients showed a variety of characteristics, many of which have previously been shown to be indicators of poor prognosis. Over the course of treatment patients became less depressed. Weight gain was correlated with a decrease in depression.

1. Further confirmation is presented in support of the relationship between the presence of vitamin A in the milk and its supply in the food.
2. The influence of the supply of the vitamin A in the food on the quantity or fat content of the milk is uncertain, in any case it appears to be much less than that produced by turning the cows out to grass.
3. The increase of the vitamin A-content of the milk produced by feeding cod liver oil is not accompanied by a rise in the lipochrome pigments as is the case when the cows are turned out to grass.
4. Up to 4 ounces per day of a good quality cod liver oil produced no fishy flavour in the milk or butter of one cow, but further experiments appear desirable.
5. Stall feeding even when ensilage was used causes the winter milk to be lower in vitamin-content than summer milk; this is mitigated by such restricted grass feeding as is possible in the south of England.

(1) Further experiments are described, the results of which support the relationship between the presence of vitamin A in the diet of the cow and its presence in milk fat.
(2) The typical winter ration of concentrates, roots and hay may be adequate to maintain the vitamin A value of the milk fat for considerable periods provided that at least one of the components supplies adequate amounts of that dietary principle. Well cured green meadow hays are in this respect greatly superior to dry brown seeds hays.
(3) The addition of cod liver oil to a winter ration deficient in vitamin A will induce a sharp rise in the vitamin A value of the milk fat of cows. No such effect is seen when oils deficient in this dietary factor (coconut oil, arachis oil) are given.
(4) The administration of cod liver oil in doses from 1 to 8 ozs. daily to milking cows caused no “fishy” taint in the milk or butter-fat.
(5) The administration of cod liver oil caused no appreciable change in the yield of milk but the higher doses appeared to cause a noticeable drop in the percentage of fat. Further experiments are required to throw more light on this observation.

Summary
Earmarking – designating money for specific projects in bills or committee reports – was made more transparent by new rules adopted in 2007. Washington Post writers Solomon and Birnbaum report on legislators' continuing practice of lobbying executive agencies on behalf of projects to be built in their districts and states. When the lobbying originates with legislators whose support is critical to an agency, the pressure on the agency is considerable and, at least in appearance, circumvents the new rules. Agencies that yield to the pressure gain no additional budget, at least not immediately, but they reduce the funding available for other projects and activities while complying with the wishes of important legislators.
Rep. Rahm Emanuel was extremely proud when the House passed a major spending bill early this year that contained not a single special-interest project. “This is an earmark-free bill,” the Illinois Democrat jubilantly declared on Feb. 1.
A week later, however, he and 18 other Illinois lawmakers signed a letter to the Energy Department to “express our strong support” for a bio-energy project at the University of Illinois. Emanuel also sent his own letter to the department seeking “support and assistance in securing” $500,000 for Children's Memorial Hospital in Chicago and $750,000 for the Illinois Institute of Technology.
Such requests for specific institutions are commonly known as earmarks. But Emanuel, a member of the Democratic House leadership, declines to call them that. “Letter-writing is not an earmark,” he said in an interview.

Although the IUD is an extremely effective and low-cost contraceptive method, its use has declined sharply in Kenya in the past 20 years. A study tested the effectiveness of an outreach intervention to family planning providers and community-based distribution (CBD) agents in promoting use of the IUD in western Kenya. Forty-five public health clinics were randomized to receive the intervention for providers only, for CBD agents only, for both providers and CBD agents, or no detailing at all. The intervention is based on pharmaceutical companies’ ‘detailing’ models and included education/motivation visits to providers and CBD programmes, as well as provision of educational and promotional materials. District health supervisors were given updates on contraceptives, including the IUD, and were trained in communication and message development prior to making their detailing visits. Detailing only modestly increased the provision of IUDs, and only when both providers and CBD agents were targeted. The two detailing visits do not appear sufficient to sustain the effect of the intervention or to address poor provider attitudes and lack of technical skills. The cost per 3·5 years of pregnancy protection was US$49·57 for the detailing intervention including the cost of the IUD, compared with US$15·19 for the commodity costs of the current standard of care – provision of the injectable contraceptive depot-medroxyprogesterone acetate (DMPA). The effectiveness of provider-based activities is amplified when concurrent demand creation activities are carried out. However, the cost of the detailing in comparison to the small number of IUDs inserted indicates that this intervention is not cost-effective.

Background. The question of whether unipolar clinical depression differs categorically from limited depressive complaints has important implications for the disorder's assessment, treatment and research. This crucial issue has proven difficult to resolve, in part because many studies to date have relied on self-report measures or on clinically homogeneous samples. We therefore applied Meehl's taxometric method to a large, clinically heterogeneous sample, and examined the latent structure of depressive episodes using both self-report and structured clinical interview data.
Method. Data were derived from the Oregon Adolescent Depression Project, a large longitudinal community study. All analyses involved more than 1400 participants. MAXEIG (MAXimum EIGenvalue) and base rate estimation were performed separately for Beck Depression Inventory (BDI) items and for DSM-IV-based major depressive episode (MDE) symptoms.
Results. MAXEIG analyses of the BDI and MDE indicator sets appeared to converge on a taxonic structure for unipolar depression. Base rate estimates overall implied a latent depressive episode class that occurs more frequently than diagnosable MDEs but less frequently than persistent depressed or anhedonic mood.
Conclusions. These findings provide tentative support for a categorical conceptualization and make it very clear that the continuity controversy regarding unipolar depression has not yet been decided in favor of dimensionality. To reconcile the conflicting reports to date, several data analytic and sampling issues need to be explored systematically.

Summary
The success of a volume like this can be measured by its power to compel us to browse through its pages (thank goodness for paper!), to take excursions into its texts (praised be prose!), to create or extend relationships with its authors (thank G-d for friends!), to sense the shape of the landscape by hovering over its table of contents (some structure is good!), and, finally, to settle back, lengthen our focal point, and take the time to reflect on critical questions (time, oh precious time!). How did we get here? What, if anything, is being said here that could not have been said before? And why are we saying it now?
The contributors to this volume and the diverse participants at a Darden Graduate School of Business Administration colloquium in spring 2002, which set this book in motion, pose these questions even more pointedly: How have we – the practitioners and stakeholders in the art of creating learning cultures – learned what we know? What do we need to learn next? Beyond articulating these essential questions, the contributors to this volume offer some answers.
It takes twenty years
It was in 1990, with Peter Senge's The Fifth Discipline: The Art and Practice of the Learning Organization, that learning was first catapulted from the peripheral corporate domains of training and development departments to a place much closer to the center of business discourse.

Background:
Review of health plan administrative data has been shown to be more sensitive than other methods for identifying postdischarge surgical-site infections (SSIs), but there has not been a direct comparison between this method and hospital-based surveillance for all infections, including those diagnosed before discharge. We compared these two methods for identifying SSIs following coronary artery bypass graft (CABG) procedures:.
Methods:We studied 1,352 CABG procedures performed among members of one health plan from March 1993 through June 1997. Health plan administrative records were reviewed based on claims containing diagnoses or procedures suggestive of infection or outpatient dispensing of antibiotics appropriate for SSI. Hospital-based surveillance information was also reviewed. SSI rates were calculated based on the total events identified by either mechanism.
Results:Postdischarge information was reviewed for 328 (85%) of 388 procedures. SSIs were confirmed in 167 patients (13% overall risk of confirmed SSI; range, 3% to 14% in the 5 hospitals). The overall sensitivity of hospital-based surveillance was 49.7% (83 of 167), and that of health plan data was 71.8% (120 of 167). There was no significant difference among hospitals in the sensitivity of either surveillance mechanism.
Conclusions:Surveillance based on health plan data identified more postoperative infections, including those occurring before discharge, than did hospital-based surveillance. Screening administrative data and pharmacy activity may be an important adjunct to SSI surveillance, allowing efficient comparison of hospital-specific rates. Interpretation of differences among hospitals' infection rates requires case mix adjustment and understanding of variations in hospitals' discharge diagnosis coding practices

In 17 adult and 3 full term fetuses the hip joints were dissected to expose the insertion of gluteus minimus. An attachment of the deep surface of the tendon as it passes over the hip joint capsule was found in every case. Histological examination of this insertion confirmed the presence of short intramuscular tendons firmly anchoring the tendon to the capsule. It is suggested that this attachment retracts the capsule during hip joint motion, thereby preventing capsular entrapment.
