Behaviour Changes

Return rates of different tag types used on Australian salmon were briefly reviewed. Internal tags, especially with attached plastic streamers, were clearly superior. The effects of time held before tagging and injury (including scale removal) on return rate were investigated. There was no evidence of any mortality caused by these factors and salmon appear to be a robust species, little affected by the stress caused by tagging operations. However, when fish were held under adverse conditions for long periods, or when wounds were pronounced, behaviour changes were evident, which resulted in the non- participation of affected fish in movements from juvenile to adult areas. Such behavioural changes may be of importance in analysing tag data from other pelagic migratory species that could be more easily affected by stress.

The purpose of this study is to evaluate the effectiveness of the West Virginia Program to Increase Colorectal Cancer Screening in implementing patient reminders to increase fecal immunochemical test (FIT) kit return rates in nine federally qualified health centers (FQHCs). Using process measures and cost data collected, the authors examined the differences in the intensity of the phone calls across FQHCs and compared them with the return rates achieved. They also reported the cost per kit successfully returned as a result of the intervention. Across all FQHCs, 5,041 FIT kits were ordered, and the initial return rate (without a reminder) was 41.1%. A total of 2,201 patients received reminder phone calls; on average, patients received 1.61 reminder calls each. The reminder interventions increased the average FIT kit return rate to 60.7%. The average total cost per FIT kit returned across all FQHCs was $60.18, and the average cost of only the reminders was $11.20 per FIT kit returned. FQHCs achieved an average increase of 19.6 percentage points in FIT kit return rates, and costs across clinics varied. Clinics with high-quality health information systems that enabled tracking of patients with minimal effort were able to implement lower cost reminder interventions.

Abstract We estimated annual return rate, fidelity, and breeding dispersal in a migratory population of Flammulated Owls (Otus flammeolus) in central Colorado. Return rates, based on capture-recapture histories of 39 males and 52 females from 1981 to 2003, were higher for males (84%) than for females (45%). Annual recapture probability was higher for females, because breeders are easier to capture than nonbreeders and females always attempted to nest, whereas some males were unpaired (did not nest) for up to four years. Territory fidelity was male biased (92%, vs. 56% for females, adjusted for undetected emigration), and mean tenure on territories was more than twice as long for males as for females. Females, but not males, had lower return rates to territories in the year following nesting failure compared with females whose nests were successful. Most males appeared to occupy one territory their entire reproductive lives, countering predictions of habitat-selection models that individuals should move to higher-quality habitats when they become available. We estimated that 74% of pairs retained the same mate in consecutive nesting attempts, but mates that bred together for multiple years had no reproductive advantages over mates that bred together for the first time. In most cases, females dispersed from territories if their mates did not return. When females dispersed, they went to territories where total productivity over the study and lifetime reproductive success of new mates were higher than on original territories, which supports the hypothesis that dispersal by females increases individual fitness.

Return Rates

Zooarchaeological hypotheses concerning prehistoric transport, processing decisions, and social stratification are often tested by correlating archaeological element frequencies with indices of the economic utility of carcass parts. Such indices have not been developed for one of the largest and most important mammals in Eastern Woodlands prehistory, the white-tailed deer (Odocoileus virginianus). We present kilocalorie (Kcal) yields and return rates of meat and marrow from a sample of several white-tailed deer. We then compare the meat and marrow data with skeletal element abundance in two Late Archaic assemblages from New York and a Middle Woodland/early Late Woodland assemblage from Illinois. In both examples, archaeological element abundance is positively correlated with marrow yield and return rate, but negatively correlated or uncorrelated with meat yield and return rate. These results do not provide evidence for differential transport of higher meat-yield carcass parts, but instead may indicate differential processing of high-yield marrow bones after entire deer carcasses were transported to the sites.

Data on 16406 cows (6025 recorded) from the area of the East & Central Al Society were analysed by least squares procedures. Ketosis incidence was determined from the milk by a commercial keto test reagent by AI technicians in connection with the ordinary first insemination of a particular cow. Ketosis incidence was on average 11.5 %, increased up to about the 4th - 5th parity and was significantly higher in larger herds. Breed did not significantly affect ketosis incidence. There was a tendency for higher incidence with increasing usage of commercial feed mixtures. Cows with ketosis milked less than unaffected ones and cows inseminated earlier than 60 days after calving had significantly higher incidence than cows inseminated later. The complete statistical models accounted for only 5 % (all herds) and 9 % (recorded herds) of variation in ketosis incidence, indicating the need for better measures of the herd environment. Heritabilities for ketosis incidence were not significantly different from zero. Cows with ketosis had significantly poorer non-return rates than unaffected ones, indicating the need for prophylactic measures.

Lateral Sclerosis

Objective Approximately 50% of amyotrophic lateral sclerosis (ALS) patients have cognitive and behavioural dysfunction in varying degrees and forms. Previous studies have shown that cognitive and behavioural changes may indicate a poor prognosis, and cognitive function gradually deteriorates over the course of disease, but the results of different studies have been inconsistent. In addition, there are relatively limited long-term follow-up studies tracking death as an endpoint. The purpose of this study was to investigate the clinical prognostic characteristics of ALS patients with cognitive behavioural changes through long-term follow-up in a cohort. Methods A total of 87 ALS patients from 2014 to 2015 in the Third Hospital of Peking University were selected and divided into a pure ALS group, an ALS with behavioural variant of frontotemporal dementia (ALS-bvFTD) group, and an ALS with cognitive and behaviour changes group. All patients were followed up for 60 months. The main end point was death and tracheotomy. Results There was no significant difference in survival curve between pure ALS and ALS with cognitive and behavioural change group, but the survival time of ALS-bvFTD group was significantly lower than the other two groups (P < 0.001). For those who was followed up to the endpoint, the survival time of the ALS-bvFTD group was significantly shorter than that of the pure ALS group (t = 5.33, p < 0.001) or the ALS with cognitive and behaviour changes group (t = 4.25, p < 0.001). The progression rate of ALS Functional Rating Scale–Revised (FRS-R) scores from recruitment to endpoint was significantly faster in the ALS-bvFTD group than in the pure ALS group (z = 2.68, p = 0.01) or the ALS with cognitive and behavioural changes group (z = 2.75, p = 0.01). There was no significant difference in survival time (t = 0.52, P = 0.60) or FRS-R score progression rate (z = 0.31, p = 0.76) between the pure ALS group and the ALS with cognitive and behavioural changes group. The total Edinburgh Cognitive and Behavioural Amyotrophic Lateral Sclerosis Screen (ECAS) score was positively correlated with survival time (r = 0.38, p = 0.01). Conclusion ALS-bvFTD patients have shorter survival time. The total ECAS score may be correlated with survival time.

Capital Return

One can suspect that capital return rate in forestry can be maximized by growing trees experiencing a value-adding assortment transition. Such a situation may or may not endure. We investigate the financial feasibility of a few harvesting schedules for a semi-shade-tolerant tree species. Some example stands have experienced commercial low thinning, whereas others have experienced young stand cleaning only. High thinning is computationally combined with quality thinning, and further growth of trees is estimated using an applicable growth model. High capital return rates are gained by diameter-limit cutting to the transition diameter between pulpwood and sawlogs. Repeated thinnings lead to a reduction in the capitalization during several decades, the system approaching a stationary state. The transient forest stands investigated show a significant excess capital return, in relation to the stationary state, and this excess return is due to transient tree size distribution. Correspondingly, capital return rate gained in rotation forestry is somewhat higher than that of stationary continuous-cover forestry, and the volumetric yield is much higher. The productive capacity of stands previously thinned from below has been apparently ruined by that treatment.

The Difference

A series of studies was conducted in 1968 and 1969 to compare fertilization rates, return rate, and sperm distribution in the genital tract in Bungaree and Peppin Merino ewes. Differences in lambing rates of the two ewe strains were demonstrated, but there was no major difference in fertilization rate in either year. A significantly higher proportion of Bungaree ewes had less than 1000 sperm in the fallopian tubes 24 hours after service, but there were no significant differences in any other character examined. Contrary to an earlier report, fertilization failure is unlikely to have been a major cause of a difference in the fertility of the two strains in the two years, and embryonic loss is likely to have made a significant contribution to the difference in their fertility.

1 Background: For asymptomatic women aged 50 to 74 with an average risk for developing breast cancer, screening mammography (SM) is recommended every 2 years in British Columbia (BC). The Screening Mammography Program of BC (SMP) uses a schedule of multiple postcard reminders, which achieves an on-time (within 30 months) participation rate of 54% among those aged 50 to 69. The purpose of this study was to determine whether the SM return rate of overdue women could be improved by a reminder letter signed by their family physicians. Methods: Eligible women met the following criteria: prior normal SM, age 52 to 74, overdue by 30 to 48 months from their last SM and had agreed to being contacted for research by the SMP. All family physicians in BC were invited to participate. Consenting physicians signed the study letters, which encouraged SM, for all of the overdue women in their practice. Women were randomized to receive a postcard reminder or a postcard reminder and the signed family physician reminder letter. Six months after the mailing, the SMP database was queried to determine the SM return rate. Results: In BC, 822 physicians participated in the study and 5,385 women with signed letters were randomized. SMP sent a postcard to 2,689 women and a postcard and letter to 2,696 women. The age, number of prior SMs and time overdue were not statistically different between the arms. Within 6 months, 600 women (22.3%) in the postcard arm returned, while 894 women (33.2%) in the postcard and letter arm returned (odds ratio 1.7, p < 0.0001). The maximum difference between the SM return rates was observed at 4 months. On multivariable analysis, women who had >1 previous SM were more likely to return compared to those who only had 1 previous SM (odds ratio 2.2, p < 0.0001). Women who were 30 to 36 months overdue were more likely to return compared to those who were 42 to 48 months overdue (odds ratio 2.4, p < 0.0001). Conclusions: A signed family physician reminder letter is a simple and effective intervention to improve screening mammography return rates in overdue women.

Return Rates

A study using 1,008 “lost letters” was designed to test the hypotheses that returned responses would be greater in smaller rural communities than from cities, that addressees' affiliation with a group opposed to physical education in schools would reduce the return rate, and that a person-positivity effect would influence return rates. Community Size and Person-Positivity conditions were not significantly associated with different rates of return even though returned letters from the smaller rural communities were more frequent than those from the cities across addressee conditions. Findings seem to suggest no community bias in the willingness of people to help a stranger in need by returning a lost letter. Person-Positivity conditions did not seem to improve the technique. Both addressees' affiliations alone and community size and addressees' affiliations were associated with significantly different rates of return in smaller rural communities, with rates of return greater in the smaller rural communities than in the cities (except for the addressee opposed to physical education in schools).
