Synthesis of the Giant Dielectric Constant Material CaCu3Ti4O12 by Wet-Chemistry Methods†

Abstract: CaCu3Ti4O12 (CCTO) has a giant dielectric constant of up to 105 at room temperature and great potential for technological application. In this work, we report two wet-chemistry methods to synthesize CCTO at relatively low temperatures and short reaction times. The pure-phase sample was obtained at 800 °C for 0.5 h, and the grain size of a pellet sample sintered at 1030 °C has a homogeneous distribution in the range of 0.4–1.5 µm.

Spirituality and religion in training, practice and personal development

Abstract: In the midst of a revitalized interest in spirituality and religion in Western societies, there has been reported a resurgence of activity regarding spirituality and religion in the mental health professions, including marriage and family therapy (MFT). Little is known, however, about the beliefs, behaviours, and training experiences of MET graduate students. Therefore it is important to examine the training (education and supervision) needs in this area. For this initial study, a sample of US MET graduate students were surveyed regarding their spiritual and religious attitudes and practices in their personal and professional lives. In most areas, graduate students were found to be similar to the previously published reports of practising professionals. In other areas, they report even more investment in spirituality and religion. The results of the survey suggest a need to include systematic attention to these areas in graduate training curricula and in the professional supervision process.

The effect of weight training on bone mineral density and bone turnover in postmenopausal breast cancer survivors with bone loss: a 24-month randomized controlled trial

Abstract: This study examined whether 24 months of weight training exercises enhanced the effectiveness of risedronate, calcium, and vitamin D in maintaining or improving bone mineral density (BMD) in 223 postmenopausal breast cancer survivors. Subjects who were ≥50% adherent to exercise had no improvement in BMD but were less likely to lose BMD. This study examined whether (1) postmenopausal breast cancer survivors (BCS) with bone loss taking 24 months of risedronate, calcium, and vitamin D had increased bone mineral density (BMD) at the total hip, femoral neck, L1-L4 spine, total radius and 33% radius, and decreased bone turnover; (2) subjects who also participated in strength/weight training (ST) exercises had greater increases in BMD and greater decreases in bone turnover; and (3) subjects who also exercised were more likely to preserve (at least maintain) BMD. Postmenopausal BCS (223) were randomly assigned to exercise plus medication or medication only groups. Both groups received 24 months of 1,200 mg of calcium and 400 IU of vitamin D daily and 35 mg of risedronate weekly, and the exercise group additionally had ST exercises twice weekly. After 24 months, women who took medications without exercising had significant improvements in BMD at the total hip (+1.81%) and spine (+2.85%) and significant decreases in Alkphase B (−8.7%) and serum NTx (−16.7%). Women who also exercised had additional increases in BMD at the femoral neck (+0.29%), total hip (+0.34%), spine (+0.23%), total radius (+0.30%), and additional decreases in Alkphase B (−2.4%) and Serum NTx (−6.5%). Additional changes in BMD and bone turnover with exercise were not significant. Subjects who were ≥50% adherent to exercise were less likely to lose BMD at the total hip (chi-square [1] = 4.66, p = 0.03) and femoral neck (chi-square [1] = 4.63, p = 0.03). Strength/weight training exercises may prevent loss of BMD in postmenopausal BCS at risk for bone loss.

Classifying credit card accounts for business intelligence and decision making: a multiple-criteria quadratic programming approach

Abstract: A major challenge in credit card portfolio management is to classify and predict credit cardholders' behaviors in a reliable precision because cardholders' behaviors are rather dynamic in nature. This is crucial for creditors because it allows them to take proactive actions and minimize charge-off and bankruptcy losses. Although the methods used in the area of credit portfolio management have improved significantly, the demand for alternative and sophisticated analytical tools is still strong. The objective of this paper is to propose a multiple criteria quadratic programming (MCQP) to classify credit card accounts for business intelligence and decision making. MCQP is intended to predict credit cardholders' behaviors from a nonlinear perspective that is justifiable because both the objective functions and constraints in credit card accounts classification may be nonlinear. Using a real-life credit card dataset from a major US bank, the MCQP method is compared with popular and similar classification metho...
