Runoff Losses of Atrazine, Metribuzin, and Nutrients as Affected by Management Practices for Sugarcane (Bulletin #875)

A primary objective of this investigation was to evaluate the effectiveness of selected pesticide management practices on the movement of atrazine and metribuzin in surface runoff from sugarcane fields in south Louisiana.https://digitalcommons.lsu.edu/agcenter_bulletins/1026/thumbnail.jp

Effect of Application Frequency on the Fate of Azinphosmethyl in a Sugercane Field (Bulletin #863)

Reducing the amounts of dissolved substances in surface and ground water is of major concern nationally and within the agricultural community. The primary focus of this study was to investigate the fate of azinphosmethyl (Guthion®) in sugarcane canopy, soil and runoff water.https://digitalcommons.lsu.edu/agcenter_bulletins/1014/thumbnail.jp

Herbicide Retention and Runoff Losses as Affected by Sugarcane Mulch Residue (Bulletin #883)

The Control, Development and Utilization of the Missouri River and its Tributaries

The speakers at this conference were Professors Condra, Caldwell, Stout, Phillips, Bengtson, and Gov. George L. Sheldon, with Dean Charles E. Bessey presiding. The principal object of the meeting was to make known reliable information in regard to the Missouri river, concerning which there is widespread interest and in some instances a tendency to magnify the future possibilities of the river. This paper is an account of the conference. It gives some of the thoughts that were emphasized at the symposium, reciting the facts as they were given by those who have investigated the respective phases of the theme.

Visions in monochrome: Families, marriage and the individualisation thesis

This paper takes issue with the way in which the individualisation thesis – in which it is assumed that close relationships have become tenuous and fragile - has become so dominant in ‘new’ sociological theorising about family life. Although others have criticised this thesis, in this paper the main criticism derives from empirical research findings carried out with members of transnational families living in Britain whose values and practices do not fit easily with ideas of individualisation. It is argued that we need a much more complex and less linear notion of how families change across generations and in time

Alienation and Age: A Coniexi.Specific Approach*

ABSTRACT A context-specific conceptualization of alienation is used to describe age-group differences. Traditionally, alienation has been treated in terms of specific, modes (e.g., powerlessness, meaninglessness, normlessness, social isolation, self-estrangement). This research adds to each of these modes social structural contexts (e.g., polity, economy, education, religion, family) to produce a matrix of context-specific alienation. Age-group differentials on specific components of alienation are examined in a three-generation sample. The postulate that alienation is related to position in the social structure leads to the hypothesis that there is a curvilinear relation between alienation and age, the youth most alienated, the middle-aged least, and the elderly in between. The hypothesis is generally supported

Formalized Verification of Snapshotable Trees: Separation and Sharing

Abstract. We use separation logic to specify and verify a Java program that implements snapshotable search trees, fully formalizing the specification and verification in the Coq proof assistant. We achieve local and modular reasoning about a tree and its snapshots and their iterators, although the implementation involves shared mutable heap data structures with no separation or ownership relation between the various data. The paper also introduces a series of four increasingly sophisticated implementations and verifies the first one. The others are included as future work and as a set of challenge problems for full functional specification and verification, whether by separation logic or by other formalisms.

Peripheral Artery Disease Prevalence and Incidence Estimated From Both Outpatient and Inpatient Settings Among Medicare Fee‐for‐Service Beneficiaries in the Atherosclerosis Risk in Communities (ARIC) Study

BACKGROUND: Outpatient ascertainment of peripheral artery disease (PAD) is rarely considered in the measurement of PAD clinical burden; therefore, the clinical burden of PAD likely has been underestimated while contributing to a decreased awareness of PAD in comparison to other circulatory system disorders. METHODS AND RESULTS: The purpose of this study was to estimate the age-standardized annual period prevalence and incidence of PAD in the outpatient and inpatient settings using data from the Atherosclerosis Risk in Communities (ARIC) study linked with Centers for Medicare and Medicaid Services claims. The majority (>70%) of all PAD encounters occurred in the outpatient setting. The weighted mean age-standardized prevalence and incidence of outpatient PAD was 11.8% (95% CI 11.5-12.1) and 22.4 per 1000 person-years (95% CI 20.8-24.0), respectively. Black patients had higher weighted mean age-standardized prevalence (15.6%; 95% CI 14.6-16.4) compared with white patients (11.4%; 95% CI 11.1-11.7). Black women had the highest weighted mean age-standardized prevalence (16.9%; 95% CI 16.0-17.8). Black patients also had a higher incidence rate of PAD (31.3 per 1000 person-years; 95% CI 27.3-35.4) compared with white patients (25.4 per 1000 person-years; 95% CI 23.5-27.3). PAD prevalence and incidence did not differ by sex alone. CONCLUSIONS: This study provides comprehensive estimates of PAD in the inpatient and outpatient settings where the majority of PAD burden was found. PAD is an important circulatory system disorder similar in prevalence to stroke and coronary heart disease
