PRELIMINARY EVALUATION OF A GRANULAR TRIMETHACARB FORMULATION FOR DETERRING GRAZING BY AMERICAN COOTS

In a 0.2 ha flight pen, groups of 4 American coots were tested to determine if their grazing activity could be affected by application of a registered granular-trimethacarb insecticide. In the 3 days following treatment (3 kg/ha, a.i.), grazing activity in the treated portions of the 200 m2 experimental plots was reduced an average of 47X. Overall use of the treated areas followed a similar pattern but was less consistent among groups. The addition of methylpyrazine, a strong odorant, produced a strong initial suppression of grazing activity in the treated halves of the plots. However, subsequent rain and a change in the coots\u27 grazing behavior prevented a definitive evaluation of the methylpyrazine treatment. Two birds that died during the trimethacarb-only portion of the study did not have abnormally low levels of brain cholinesterase. However, this finding does not preclude the possibility that they were unable to distinguish treated from untreated grass and consumed lethal amounts of trimethacarb. Additional investigation of methylpyrazine appears warranted; such materials may act to decrease the likelihood that birds will ingest lethal quantities of repellent

Customer Satisfaction, Loyalty and Repurchase: Some Evidence from Apparel Consumers

While customer satisfaction, loyalty and repurchase intent are some of the most researched areas in marketing and consumer behavior, there is little certainty on the direction and strength of these relationships. After completing a literature review, this study develops a model of loyalty dimensions, satisfaction and repurchase intent. A sample of 499 respondents who had purchased jeans was interviewed in the Southeastern United States. Results were analyzed using Structural Equation Modeling. The results of nine hypothesized relationships are discussed. A significant positive relationship exists between commitment and repurchase/repurchase intent. Some surprising findings also emerged as the model was modified. It is clear that loyalty dimensions, repurchase/repurchase intent, and satisfaction are linked and influence each other

Customer Loyalty, Repurchase and Satisfaction: A Meta-Analytical Review

The purpose of this article is to investigate the relationship between customer loyalty, repurchase/repurchase intent and satisfaction in order to attempt to resolve the mixed views on these concepts. A quantitative review of loyalty-repurchase satisfaction constructs was conducted to identify the strength and direction of the researched relationships and the influence of possible moderating factors affecting those relationships. The Hunter and Schmidt (1990) meta-analytical technique and software were employed. The results demonstrate that loyalty and satisfaction indicate strong positive relationships (0.54). Repurchase and satisfaction display a complicated relationship, which confirmed the view that satisfaction does not explain repurchase behavior. Repurchase intent and satisfaction display strong positive relationships in the meta-analysis (0.63) and moderator analyses. Loyalty and repurchase/repurchase intent indicate the strongest positive relationship (0.71) among all conducted analyses. This study provides value to managers dealing with customer satisfaction, loyalty, and repurchase by presenting a detailed overview of these three concepts, and relationships between them

Double-crested Cormorants

The history of conflict between double-crested cormorants (Figure 1) and human interest in fisheries is long and convoluted. Following a low point in the 1970s, populations of cormorants expanded in North America, as did concerns about impacts on fisheries. By the late 1990s, natural resource agencies in 27 states reported losses of free-ranging fish stocks to cormorants. Agencies in 10 states, ranging from the Southwest to the Northeast, considered cormorant predation to be of moderate to major concern to fishery management. Overall, double-crested cormorants are not major consumers of commercial and sportfish species. However, exceptions have been recorded at specific sites with documented impacts on local fisheries (see Damage to Fisheries section). Cormorants often congregate and can have significant local impacts where high concentrations of fish occur, such as stocking release sites, private fishing ponds, aquaculture ponds, reservoirs, spawning sites, and other areas. Cormorants may be managed whenever their damage justi-fies the granting of the permits necessary to control them. Adult cormorants eat approximately 19 ounces of food per day, so local impacts of large flocks on fisheries can be substantial. Although cormorants frequently are blamed for reductions in fish harvests, this is not always substantiat-ed. Sometimes other factors, such as pollution, invasive species, and habitat loss may be the primary factor or con-tributing factors in the decline of fisheries

Complexity of Fetal Movement Detection Using a Single Doppler Ultrasound Transducer

The objective of this paper is to discuss the complexity of fetal movement detection encountered during development and implementation of an automated single Doppler ultrasonic transducer based instrument. The single transducer instrument was intended to better quantify the duration, velocity, and magnitude of fetal movements. A Corometrics Model 116 fetal heart rate monitor was modified, and a fetal movement detection algorithm (Russell Algorithm) was developed to detect fetal movements on one and two (data fusion) transducers. A Hewlett-Packard (HP) M-1350-A fetal monitor and the Russell Algorithm were used to detect and record fetal movements concurrently on sixty patients between the gestation ages of31 to 41 weeks. Using a computer-controlled SVHS PC-VCR, the instrumental detection of fetal movements was time-linked with real-time video ultrasound. This allowed the fetal movements to be scored by expert examiners on a second-per-second basis. A total of 52,478 seconds of fetal movements was scored using this system. Neither system could accurately define the entire duration, velocity, or magnitude of the fetal movements as detected by real-time ultrasound. The complexity of detecting fetal movements using only one transducer has many shortcomings, such as: the amplitude of the returning Doppler signal, the small area of the fetus monitored by a single transducer, the position of the fetus, the type and variety of fetal movements, and material size and shape

Biosimilar infliximab use in paediatric IBD

Background Biosimilar infliximab became available in the UK in 2015. Paediatric experience to date on its use is limited. We prospectively evaluated the safety and efficacy of biosimilar infliximab (Remsima) in two paediatric gastroenterology networks in patients with inflammatory bowel disease. Methods Prospective clinical data were collected from laboratory reports, electronic patient records and case notes of 40 patients starting Remsima for the first time. Disease activity scores together with blood and stool biomarkers were used to assess response. Results Our data set highlights that Remsima was associated with a significant clinical and biochemical improvement (p<0.01 or less for all parameters assessed) in Crohn’s disease post induction. There were no significant safety issues noted. The total cost saving was £47 800, representing a 38% reduction from originator. Conclusion We found that biosimilar infliximab is as effective as originator infliximab and its use is associated with significant cost savings

Clinical Significance of Bronchodilator Responsiveness Evaluated by Forced Vital Capacity in COPD: SPIROMICS Cohort Analysis.

ObjectiveBronchodilator responsiveness (BDR) is prevalent in COPD, but its clinical implications remain unclear. We explored the significance of BDR, defined by post-bronchodilator change in FEV1 (BDRFEV1) as a measure reflecting the change in flow and in FVC (BDRFVC) reflecting the change in volume.MethodsWe analyzed 2974 participants from a multicenter observational study designed to identify varying COPD phenotypes (SPIROMICS). We evaluated the association of BDR with baseline clinical characteristics, rate of prospective exacerbations and mortality using negative binomial regression and Cox proportional hazards models.ResultsA majority of COPD participants exhibited BDR (52.7%). BDRFEV1 occurred more often in earlier stages of COPD, while BDRFVC occurred more frequently in more advanced disease. When defined by increases in either FEV1 or FVC, BDR was associated with a self-reported history of asthma, but not with blood eosinophil counts. BDRFVC was more prevalent in subjects with greater emphysema and small airway disease on CT. In a univariate analysis, BDRFVC was associated with increased exacerbations and mortality, although no significance was found in a model adjusted for post-bronchodilator FEV1.ConclusionWith advanced airflow obstruction in COPD, BDRFVC is more prevalent in comparison to BDRFEV1 and correlates with the extent of emphysema and degree of small airway disease. Since these associations appear to be related to the impairment of FEV1, BDRFVC itself does not define a distinct phenotype nor can it be more predictive of outcomes, but it can offer additional insights into the pathophysiologic mechanism in advanced COPD.Clinical trials registrationClinicalTrials.gov: NCT01969344T4
