This study explicitly identifies the main values that rural welfare recipients reveal when they talk about their experiences with welfare and welfare reform. An inductive analysis of values is conducted using interview data from 49 current and former recipients of Temporary Assistance for Needy Families (TANF) residing in the states of Massachusetts, Maryland, Minnesota, and New York. Seven main values that emerge from the data are self-esteem, autonomy, uniqueness, advancement, security, independence, and fairness. A conceptual diagram of these values is developed to illustrate how these values are related

This paper proposes a simultaneous application of homogeneity analysis and fuzzy clustering with in complete data. Taking the similarity between the loss of homogeneity in homogeneity analysis and the least squares criterion in principal component analysis into account, the new objective function is defined in a similar formulation to the linear fuzzy clustering with missing values. Numerical experiment shows the characteristic properties of the proposed method.

We study the uniqueness question of transcendental meromorphic functions that share three values CM in some angular domains instead of the whole complex plane. The results in this paper extend the corresponding results in Zheng [13, 14] and Yi [12]. Some examples are given to show that the results in this paper, in a sense, are the best possible.

In order to spread the practical utilization of solar energy, it depends upon how we can increase the efficiency of solar energy conversion system. This paper describes the method for calculating of optimal passive elements values in Maximum Solar Energy Tracking System. And experimental results with those calculated values are presented.

This paper derives maximum likelihood estimators (MLEs) and some approximate MLEs (AMLEs) of unknown parameters of the generalized exponential distribution when data are lower record values. We derive approximate Bayes estimators through importance sampling and obtain corresponding Bayes predictive intervals for unknown parameters for lower record values from the generalized exponential distribution. For illustrative purposes, we examine the validity of the proposed estimation method by using real and simulated data.

arraylmpute is a software for exploratory analysis of missing data and imputation of missing values in microarray data. It also provides a comparative analysis of the imputed values obtained from various imputation methods. Thus, it allows the users to choose an appropriate imputation method for microarray data. It is built on R and provides a user-friendly graphical interface. Therefore, the users can easily use arraylmpute to explore, estimate missing data, and compare imputation methods for further analysis.

The effects of additions of lotus leaf (0.1 and 0.5%) and barley leaf powder (0.1 and 0.5%) on the lipid oxidation and microbiological analysis of raw minced pork were investigated after 1, 4, 7, and 10 d at chilled storage. Days of storage caused (p<0.05) decreases in pH values in samples with lotus leaf (LP) and barley leaf powder (BP). $L^*$ and $a^*$ values decreased, and $b^*$ values increased in the treatments with increasing lotus leaf and barley leaf powder contents, respectively. The decrease in $a^*$ values was lowest (p<0.05) in the treatment with 0.1% BP. Thiobarbituric acid reaction substance values and free fatty acids in 0.5% LP were lowest (p<0.05) on day 10. Thus, the addition of lotus leaf powder significantly improved lipid oxidative stability in the raw minced pork during chilled storage of 10 d. Furthermore, the raw minced pork treatments with LP and BP presented low peroxide values and total microbes as compared to control (-) (without LP and BP). These results indicate that LP and BP can be incorporated into raw minced pork as natural additives to retard oxidation.

The acrylic resin was first introduced as denture base materials in 1937 and it is commonly used for denture base fabrication nowadays. Three different curing cycles (Conventional curing cycle, short curing cycle and long curing cycle) and three commercially available heat-activated acrylic resins (Vertex RS, Lucitone 199 and ProBase Hot) were investigated to find the curing cycle and material that showed the minimum shrinkage of the resin during polymerization process. A brass master mold was fabricated and duplicated by additional silicone impression material. Stone molds were made by pouring of type III dental stone (SILKY-ROCK YELLOW, Whip-Mix, Louisville, Kentucky). It was embedded in the flask. Strain gauge and thermocouple were embedded in the specimen. Strain gauge and thermocouple were connected to signal conditioning amplifier and data was recorded by pre-programmed software. The parameters ESmax (Maximum expansion strain), Sb (Strain measured just before deflasking procedure), Sa (Strain measured just after deflasking procedure) and Sf (Strain measured at the end of the experiment) were measured. ${\Delta}$S was calculated from Sb and Sa (${\Delta}$S=Sb-Sa). In the experiment concerned about materials, the parameters 90-ESmax (Maximum expansion strain measured during early 90 minutes of curing procedure), 180-ESmax (Maximum expansion strain measured from 90 minutes to 180 minutes), Sb, Sa, ${\Delta}$S and Sf were measured and the following conclusions were made. 1. The ESmax value of conventional curing cycle showed the largest value and the 180-ESmax value of Lucitone 199 showed the smallest value. 90-ESmax values showed no significant difference (p<0.05). 2. ${\Delta}$S values of conventional curing cycle showed the positive values. ${\Delta}$S values of short curing cycle and long curing cycle showed the negative values. All three materials cured by conventional curing cycle showed the positive values. 3. The Sf values of long curing cycle and ProBase Hot (cured by conventional curing cycle) showed the smallest values.

Beef fat was replaced with cold press pumpkin seed oil (PSO; 0%, 5%, 15%, and 20%) in the production of bologna-type sausages. A value of pH, water-holding capacity (WHC), jelly-fat separation, emulsion stability and viscosity values were determined in meat batters. Thiobarbituric acid reactive substances (TBARS), color, and textural characteristics (TPA, shear test, penetration test) were determined in end-product at 1, 7, 14, 21, and 28 days of storage at 4℃. The pH values were varied between 6.06 and 6.08. With the increase in the level of PSO in meat batters, there was a significant increase in WHC, jelly-fat separation and viscosity values (p<0.05) while a significant decrease in emulsion stability (p<0.05). TBARS values of sausages were found to be significantly higher than in the control group (p<0.05), and this trend continued during storage. Increasing of PSO level were caused a significant increase in L* and b* values while a decrease in a* value (p<0.05). Hardness, adhesiveness and chewiness values were significantly reduced whereas cohesiveness and resilience values increased (p<0.05). Maximum shear force and work of shear was significantly decreased as the level of PSO increased (p<0.05). Hardness, work of penetration and the resistance during the withdrawal of the probe values (penetration tests) increased significantly with the increase in the level of PSO (p<0.05). These results indicate that PSO has potential to be use as a replacement of animal-based fats in the production of bologna-type sausages.
