Production Practices of Arkansas Beef Cattle Producers
This report contains information from a 1996 survey on production practices of Arkansas beef cattle producers. While several studies have been completed on the profitability of retained ownership of beef cattle, few empirical data are available on production practices of cow/calf and stocker operations in Arkansas. This report shows that there are some differences in production methods across operation types. Further, the report summarizes demographic characteristics of Arkansas cow/calf and stocker operations. The results of this study can be particularly helpful in providing the needed data for studying the potential economic impact of feeding weaned calves to heavier weights in Arkansas as a value-added production alternative to selling calves at weaning. It should also prove helpful in the formulation of budgets and simulation models
ADOPTION OF BACKGROUNDING ON COW-CALF FARMS
A discrete choice model is used to analyze the decision to feed or sell calves at weaning. After accounting for regional factors, results show that operator perceptions toward profitability, risk, and facilities as well as control over production and attention to marketing impacted retained ownership of calves. Farm size had a minimal impact.Livestock Production/Industries,
FACTORS AFFECTING THE ADOPTION OF VALUE-ADDED PRODUCTION ON COW-CALF FARMS
Factors that affect the decision to feed or sell calves at weaning are analyzed for Arkansas cow-calf operators. A discrete choice logit model is used to analyze the adoption of value-added cattle production. Farm size, human capital, perception of risk/returns and enterprise diversification are hypothesized to explain this decision. Regional factors and land quality are also accounted for. Operator perceptions towards risk, profitability and facilities were important. Production control and attention to marketing were also significant, but farm size and scale of cattle production had a minimal impact. Effects of human capital and off-farm labor opportunities need further investigation.backgrounding, cow-calf production, production control vs. marketing, risk/return relationship, technology adoption, Livestock Production/Industries,
Marketing Practices of Arkansas Beef Cattle Producers
This report contains information from a 1996 survey on marketing practices of Arkansas beef cattle producers. While several studies have been completed on the profitability of retained ownership of beef cattle, few data are available on what marketing techniques and decision criteria cow-calf and stocker operations use to market their cattle. This report shows that there are some differences in opinions on marketing issues such as pooled cattle sales and retained ownership across cow-calf and stocker operations. Further, these operations use different sources of information to make marketing decisions. The results of this study can be particularly helpful in providing the needed data for studying the potential economic impact of feeding weaned calves to heavier weights in Arkansas as a value-added marketing alternative to selling calves at weaning
Young Children See a Single Action and Infer a Social Norm: Promiscuous Normativity in 3-Year-Olds
Human social life depends heavily on social norms that prescribe and proscribe specific actions. Typically, young children learn social norms from adult instruction. In the work reported here, we showed that this is not the whole story: Three-year-old children are promiscuous normativists. In other words, they spontaneously inferred the presence of social norms even when an adult had done nothing to indicate such a norm in either language or behavior. And children of this age even went so far as to enforce these self-inferred norms when third parties broke them. These results suggest that children do not just passively acquire social norms from adult behavior and instruction;rather, they have a natural and proactive tendency to go from is to ought. That is, children go from observed actions to prescribed actions and do not perceive them simply as guidelines for their own behavior but rather as objective normative rules applying to everyone equally
Three Wide Planetary-mass Companions to FW Tau, ROXs 12, and ROXs 42B
We report the discovery of three planetary-mass companions (M = 6-20 M_(Jup)) in wide orbits (ρ ~ 150-300 AU) around the young stars FW Tau (Taurus-Auriga), ROXs 12 (Ophiuchus), and ROXs 42B (Ophiuchus). All three wide planetary-mass companions (PMCs) were reported as candidate companions in previous binary survey programs, but then were neglected for >10 yr. We therefore obtained followup observations that demonstrate that each candidate is comoving with its host star. Based on the absolute M_K' magnitudes, we infer masses (from hot-start evolutionary models) and projected separations of 10 ± 4 M_(Jup) and 330 ± 30 AU for FW Tau b, 16 ± 4 M_(Jup) and 210 ± 20 AU for ROXs 12, and 10 ± 4 M_(Jup) and 140 ± 10 AU for ROXs 42B b. We also present similar observations for 10 other candidates that show that they are unassociated field stars, as well as multicolor JHK'L' near-infrared photometry for our new PMCs and for five previously identified substellar or planetary-mass companions. The near-infrared photometry for our sample of eight known and new companions generally parallels the properties of free-floating, low-mass brown dwarfs in these star-forming regions. However, five of the seven objects with M < 30 M_(Jup) are redder in K' – L' than the distribution of young free-floating counterparts of similar J – K' color. We speculate that this distinction could indicate a structural difference in circumplanetary disks, perhaps tied to higher disk mass since at least two of the objects in our sample are known to be accreting more vigorously than typical free-floating counterparts
