    Team payroll and team performance in major league baseball: 1985-2002

    This paper examines the relationship between team payroll and team performance in major league baseball from 1985 to 2002. The results indicate that the relationship has changed over time. Unlike the early years, there is now a much clearer relationship between payroll and performance. Specifically, in the latter part of the 1990s and continuing into the 21st century, the greater the team payroll and the more equally this payroll is distributed among team members, the better the on-field performance of the team. This is a problem of particular concern because of the growing disparity in team payrolls which, in turn, affects the competitive balance of the sport. This growing disparity was also at the heart of last year's contract negotiations between players and owners.Competitive balance Gini coefficient Perforamnce Salary structure Major League Baseball

    Working Paper: Domestic Violence Prevention Education for Middle School and High School Students in the State of California

    Get PDF
    California has been a leader in policy across the globe, but still lags behind in responding to research that shows children ages 11-17 are most vulnerable to domestic violence. While California has some of the strongest models of domestic violence prevention education for college campuses, it has failed to institute comparable systems in K-12 public education. States like Virginia and Ohio now surpass California in strong prevention policies, which outline standards for content and mandate timelines for implementation. California should implement a policy that mandates base-level orientation on domestic violence, sets a requirement for California’s health framework that includes a section dedicated to domestic violence, and incorporates out-of-classroom awareness programming

    Get PDF
    Several new diaryl diselenides having intramolecular coordinating groups have been synthesized by ortho-lithiation/Na2Se2 routes in good yield. Bis[2-(N-phenylferrocenecarboxamide)] diselenide (10), bis[2-(N-tert-butylferrocenecarboxamide)] diselenide (11), (S)(S)-bis[2(-N-phenethylferrocene-carboxamide)] diselenide (12) were synthesized by the ortho-lithiation route. Bis[2-(N,N-dimethyl-aminomethylnaphthyl)] diselenide (13) was synthesized by lithium/bromide exchange reaction whereas bis(2,4-dinitrophenyl) diselenide (14) was prepared by the reaction of disodium diselenide with 2,4-dinitro-1-chlorobenzene. Thiol peroxidase-like activities of the diorganodiselenides have been evaluated by using H2O2 as substrate and PhSH as cosubstrate. Diselenides (13) and (14) with dimethylami-nomethyl- or nitro-donor groups in close proximity to selenium, show much better thiol peroxidase-like activities compared to diselenides 10-12 with amide donor groups. Cyclic voltammetry study of diselenides 10-12 derived from redox-active ferrocenamide has been carried out

    Formulation and In-vitro Evaluation of Tolterodine Tartrate Tablets by Using High Performance Liquid Chromatographic (HPLC)

    Get PDF
    Tolterodine tartrate, is a new, potent and competitive muscarinic receptor antagonist in clinical development for the treatment of urge incontinence and other symptoms of unstable bladder. The purpose of this study is to formulation and invitro evaluation of Tolterodine tartrate by high performance liquid chromatography with ultraviolet detection (HPLC-UV). A simple, rapid, and sensitive high-performance liquid chromatographic method was developed and evaluated for invitro formulation of Tolterodine tartrate Tablets. Tablets were analysed by measuring different parameters: lubricated granules content of Tolterodine tartrate having bulk density, tap densities and angle of r content uniformity, assay and related substances. Separation of Tolterodine tartrate was achieved within a single chromatographic run on 5µm 4.6x250mm with UV detection at 280 nm, under isocratic conditions, using Acetonitrile and A mixture of 65 volumes of buffer solution prepared by mixing 2.2 ml of orthophosphoric acid to 1000 ml with water, adjusted to pH 3.0 with triethylamine in 35:65 ratio with a flow rate of 1.5 ml/min. From the results, it was clear that designed formulations among f7 displayed drug release in the range of 55.66% to 102.067% in 10 min, which showed improved invitro dissolution rate compared to other formulations as well as others parameters were found to be good as compared to other formulations. Similarly, the average content of formulation f7 was found to be 104.58% and Related substances should comply the test. Assays of f7 were found to be 96.04%, the limit is 90% - 110% of the label claim having weight variation range from  82.50 mg-91.50 mg. epose And flim coated Tolterodine tartrate tablets having friability, thickness, hardness, weight variation, invitro dissolution

    Luliconazole mostly prescribed drug for the management of superficial problems, the very simple, Fast, accurate and economical methods have been proposed for the determination of Luliconazole cream. Luliconazole  was measured by using Uv spectroscopy method with the solution of mrthanol and purified water the linearity was found to be 0.9987 and the accuracy showed mean % RSD of 0.921776 and with total meam % RSD 1.10130 in intermediate precision, robustness %RSD 0.543539 all the paranmeters values were within standard limit thus Analytical method was validated according to ICH guideline for the determination of Luliconazole cream. The method was found to be precise and validated as per ICH guidelines

    This study was conducted to develop mucoadhesive buccal tablet of Frusemide. A Mucoadhesive buccal tablet of Frusemide were prepared by using wet granulation method using dfferent polymer such as HPMC k 100, Carbopol-940 in different ratio. Tablets were analysed by measuring different parameters thickness, hardness weight uniformity, drug content uniformity, LOD, sweeling index, invitro dissolution study and solubility. The tablets were evaluated for in vitro release in pH 6.8-phosphate buffer for 12 hr in standard dissolution apparatus. Mucoadhesion strength was increased with increase in the concentration of carbopol. In order to determine the mode of release, the data was subjected to Zero order, first order, Higuchi and Peppas diffusion model

    Get PDF
    Fluconazole is a recent triazole antifungal drug that is used in the treatment of superficial and systemic fungal infection. The oral use of fluconazole is not much recommended as it has many side effects. Thus this formulation is made for better patient compliance and to reduce the dose of the drug and to avoid the side effects like liver damage and kidney damage. This research was designed to formulate & evaluate different formulation of a topical gel containing fluconazole by using a polymer with different concentration as Carbopol 940 & NaCMC. Methanol was used as a penetration enhancer. The evaluation of formulated fluconazole topical gel was carried out for a physical appearance, pH-value, spreadability, homogeneity, drug content. The formulated gel showed good physical characteristics. The formulation F3 (101.18%) & F6 (105.4%) show good drug content as the polymer concentration in them was higher. The percentage yield of F4 (98.26%) was the highest. The spreadability of gel decreases with an increase in polymer concentration. The pH of the formulation was in the range of 5-8 which is considered acceptable to avoid the risk of irritation upon application to the skin
