Determining priority importance is a matter of concerns among the organization to improve their performance. One of the important
aspects that should be considered by the organization is management of human resources, comprising of members who have their
own family life. In this paper, we deliver a new perspective for organization to provide priority importance for their members
with respect to family matters in order to inculcate the sense of belonging in the organization. To be effective in considering
family matters in the organizational policy making, closer look of family characteristics are required. The idea of translating
several family characteristics as quality variables and applying the quality function deployment (QFD) method to these variables
could present a new way of improving the decision making in the organization by considering the process of decision in the
family. Quality function deployment for family (QFDF) produces a friendly interpretation of a highly complex and intangible
matters around family life; thus, making the assessment of a family easier. QFD is applied on the data gathered from a questionnaire
survey based on 1,213 families in West Malaysia, Malaysia. Twelve variables are identified as voice of family, where seven
of them are found to have the highest priority of importance. These variables could also be translated into quality variables
in the context of organization, the strategy of improvement for the family could be interpreted as strategy for improvement
in the organization. Furthermore, the results of this study provide suggestion to improve actions for managing human resource.
In the discussion, three most high ranked variables from both perspectives of family and organization are considered. 相似文献

Association of the modified frailty index with adverse outcomes after penile prosthesis implantation
Objectives: To investigate frailty as a predictor of surgical outcome in elderly patients undergoing penile prosthesis implantation.Material and methods: A total of 54 elderly patients, above 60 years of age, underwent penile prosthesis implantation between 2012 and 2014. Their data were collected and retrospectively analyzed. A modified frailty index (mFI) was calculated for each patient based on 11 risk factors from the Canadian Study of Health and Aging Frailty Index. The 1-year adverse outcomes were correlated with mFI, patients’ and procedure’s risk factors.Results: Mean age was 64.9?±?5.2 years. No mortality was reported in our patients, however, one-year adverse outcomes were encountered in 43 (79.6%) patients. Among all studied variables, the 1-year adverse outcomes was not significantly association with mFI, but with preoperative glycosylated hemoglobin A1c (HbA1c) (p?=?0.031) and associated Peyronie’s disease (PD) (p?=?0.000). HbA1c, dyslipidemia, hypertension, PD and duration of the procedure were predictive of infection complications (p?0.05). Only PD and HbA1c sustained an independent significant impact.Conclusions: mFI is not a predictive of post-penile prosthesis implantation adverse outcomes in elderly patients with impotence. Degree of diabetic control and association with PD was associated with the 1-year adverse outcomes and infection complications. 相似文献

A random-effects meta-analysis was undertaken to examine the effectiveness of the pique technique of compliance-gaining. Results indicated an overall significant effect of the pique technique on increased compliance rate across 17 comparisons (r = .27). Moderator analyses showed the technique worked significantly better than controls in gaining compliance when a smaller amount was requested, when the reason for the request was included, and when the technique was used in France. In addition, the pique technique was more successful than control requests in terms of the total amount of money or time given by participants and the percentage of participants inquiring about the requests. Theoretical and practical implications for the success of pique technique are discussed for future research. 相似文献

Foldover techniques are used to reduce the confounding when some important effects (usually lower order effects) cannot be estimated independently. This article develops an efficient foldover mechanism for symmetric or asymmetric designs, whether regular or nonregular. In this paper, we take the uniformity criteria (UC) as the optimality measures to construct the optimal combined designs (initial design plus its corresponding foldover design) which have better capability of estimating lower order effects. The relationship between any initial design and its combined design is studied. A comparison study between the combined designs via different UC is provided. Equivalence between any combined design and its complementary combined design is investigated, which is a very useful constraint that reduce the search space. Using our results as benchmarks, we can implement a powerful algorithm for constructing optimal combined designs. Our work covers as well as gives results better than recent works of about 20 articles in the last few years as special cases. So this article is a good reference for constructing effective designs. 相似文献

This paper applies stratified random sampling using Neyman allocation to Mangat et al. (1992) unrelated question randomized response (RR) strategy for both completely truthful reporting and less than completely truthful reporting. It is shown that, for the prior information given, our new model is more efficient in terms of variance (in the case of completely truthful reporting) and mean square error (in terms of less than completely truthful reporting) than Kim and Elam's (2007) model. Numerical illustrations and graphs are also given in support of the present study. 相似文献

The crux of this article is to estimate the mean of the number of persons possessing a rare sensitive attribute based on the Mangat (1991) randomization device by utilizing the Poisson distribution in simple random sampling and stratified sampling. Properties of the proposed randomized response (RR) model have been studied along with recommendations. It is also shown that the proposed model is more efficient than that of Land et al. (2011) in simple random sampling and that of Lee et al. (2013) in stratified random sampling when the proportion of persons possessing a rare unrelated attribute is known. Numerical illustrations are also given in support of the present study. 相似文献
