BIRD DEPREDATION ON RICE AND OTHER GRAINS IN ARKANSAS

In Arkansas, blackbirds are responsible for appreciable damage to rice, grain sorghum, oats, wheat, rye, and corn. By far, the greatest damage is to rice. As is shown in the following table, the losses to rice producers amounted to an estimated $3,049,055 in 1968, the last year that a survey was made. Nearly two-thirds (63%) of this loss was to standing rice destroyed and to the cost of bird control measure in standing rice. The remaining losses ($2,140,320 ) are to seeding or to efforts to control bird depredations to new seeding, (see Table 1). Blackbird damage to grain sorghum and corn was mostly to standing grain; that to oats, wheat and rye, to seeding, although there is occasional damage to standing grain. Additional problems are caused by blackbirds in feed lots. The total losses to Arkansas agricultural producers due to blackbirds in 1968 was about $3,500,000. Bird damage in a specific locality and on specific crops seems to vary in intensity from year to year. However, surveys during the past ten years suggest a fairly consistent level of total damage state-wide. The damage in 1968-and I believe in 1969—was somewhat lighter than we have come to expect from past exper¬ience. (See table 2.) On a per acre basis the damage in 1968 showed a considerable decline when compared to previous years. A part of this decline is probably a temporary situation. Some of the decline in losses to rice and grain sorghum, however, are due to changes in varieties, such as development of bird-resistant milo, and to changes in cultural methods. Further appreciable reductions due to changes in these factors seem unlikely, (see table 3.) Since rice producers sustain the greatest losses to birds, they have generated the greatest demand for bird control programs. Three species are responsible for most of the damage to rice. They are the red-winged blackbird, common grackle and brown-headed cowbird. These birds have created problems for rice producers since the first successful rice crop was grown near Lonoke, Arkansas, in 1904.

Does Mental Illness Affect Consumer Direction of Community-Based Care? Lessons From the Arkansas Cash and Counseling Program

Purpose: Previous research from the Cash and Counseling Demonstration and Evaluation (CCDE) in Arkansas, New Jersey, and Florida suggests that giving consumers control over their personal care greatly increases their satisfaction and improves their outlook on life. Still, some argue that consumerdirected care may not be appropriate for consumers with intellectual disabilities or mental health diagnoses. This study examined how Cash and Counseling— a new option allowing consumers to manage an individualized budget equivalent to what agencies would have spent on their care—changes the way consumers with mental health diagnoses meet their personal care needs and how that affects their wellbeing. Design and Methods: Using the Arkansas CCDE baseline and the 9-month follow-up data for individuals in the treatment and control groups, we compared and contrasted the experience of elderly consumers with and without mental health diagnoses utilizing logit regression. Results: After examining several outcome measures, including satisfaction with care arrangements and the paid caregiver’s reliability and schedule, unmet needs, and satisfaction with the relationship with paid caregivers, this study found evidence that, from the perspective of consumers, the Cash and Counseling program works well for participants with mental health diagnoses. Implications: Considering the growing need for long-term-care services and the limited resources available, a consumer-directed option makes sense, and it can be a valuable alternative for persons with mental health needs.

COSTS AND EFFECTS OF ARKANSAS' LONG-TERM CARE DEMONSTRATION PROJECT (MEDICAID, CHANELLING, COMMUNITY ASSESSMENT)

The purpose of this study was to assess the impact of the Arkansas Long-Term Care Demonstration Project upon Arkansas' Medicaid expenditures and upon the clients it serves. A Retrospective Medicaid expenditure study component used analyses of variance techniques to test for the Project's effects upon aggregated expenditures for 28 demonstration and control counties representing 25 percent of the State's population over four years, 1979-1982.^ A second approach to the study question utilized a 1982 prospective sample of 458 demonstration and control clients from the same 28 counties. The disability level or need for care of each patient was established a priori. The extent to which an individual's variation in Medicaid utilization and costs was explained by patient need, presence or absence of the channeling project's placement decision or some other patient characteristic was examined by multiple regression analysis. Long-term and acute care Medicaid, Medicare, third party, self-pay and the grand total of all Medicaid claims were analyzed for project effects and explanatory relationships.^ The main project effect was to increase personal care costs without reducing nursing home or acute care costs (Prospective Study). Expansion of clients appeared to occur in personal care (Prospective Study) and minimum care nursing home (Retrospective Study) for the project areas. Cost-shifting between Medicaid and Medicare in the project areas and two different patterns of utilization in the North and South projects tended to offset each other such that no differences in total costs between the project areas and demonstration areas occurred. The project was significant ((beta) = .22, p < .001) only for personal care costs. The explanatory power of this personal care regression model (R('2) = .36) was comparable to other reported health services utilization models. Other variables (Medicare buy-in, level of disability, Social Security Supplemental Income (SSI), net monthly income, North/South areas and age) explained more variation in the other twelve cost regression models. ^

Eficiência de fontes, dinâmica do magnésio no solo sob a cultura do café no Brasil e comparação da análise de K, Ca e Mg em solos do Arkansas-EUA seco em estufa e úmido de campo

A cultura do café no Brasil tem apresentado frequente deficiência de magnésio (Mg) limitando sua produtividade, portanto faz-se necessário o estudo de fontes que contenham Mg para essa cultura. Por outro lado, o estudo das metodologias de análise de K, Ca e Mg no solo é um outro ponto que precisa ser estudado para melhor manejo da fertilidade do solo e recomendação de adubações. Objetivou-se com o primeiro experimento avaliar a eficiência de fontes de magnésio para a cultura do café e a dinâmica deste nutriente no perfil do solo. E com o experimento desenvolvido em Arkansas-EUA, avaliar as correlações entre as concentrações de nutrientes do solo seco em estufa e úmido de campo extraídos com Mehlich-3 e 1 mol L-1 NH4OAc. Observou-se que o óxido e oxissulfato de Mg elevaram os valores de pH e CTC e diminuíram a concentração de H + Al do solo. As fontes diminuíram a disponibilidade de K e Ca, e aumentaram o Mg no solo. Na planta, óxido e sulfato de Mg proporcionaram maior concentração de Mg foliar. Apenas no segundo ano de avaliação houve aumento de produtividade do café. Os fertilizantes óxido e oxissulfato de Mg obtiveram o maior índice de eficiência agronômica em relação ao carbonato de Mg. No segundo experimento, K, Ca e Mg extraíveis com Mehlich-3 e NH4OAc foram altamente correlacionados (r2> 0,95) tanto para solo úmido de campo quanto para o seco em estufa. A relação entre as concentrações de K no solo seco em estufa e úmido de campo para Mehlich-3 e NH4OAc foram muito semelhantes e altamente correlacionados (r2 = 0,92). A secagem do solo em estufa teve efeito mínimo sobre as concentrações de Ca e reduziu a concentração de Mg tanto para Mehlich-3 quanto para NH4OAc. Entre os nutrientes estudados, a concentração de K foi a mais afetada pela secagem em estufa, necessitando de pesquisas de campo para correlacionar e calibrar novas recomendações agronômicas.
