Optimal designs for rating-based conjoint experiments.

The scope of conjoint experiments on which we focus embraces those experiments in which each of the respondents receives a different set of profiles to rate. Carefully designing these experiments involves determining how many and which profiles each respondent has to rate and how many respondents are needed. To that end, the set of profiles offered to a respondent is viewed as a separate block in the design and a respondent effect is incorporated in the model, representing the fact that profile ratings from the same respondent are correlated. Optimal conjoint designs are then obtained by means of an adapted version of the algorithm of Goos and Vandebroek (2004). For various instances, we compute the optimal conjoint designs and provide some practical recommendations.Conjoint analysis; D-Optimality; Design; Model; Optimal; Optimal block design; Rating-based conjoint experiments; Recommendations;

Knowledge and Preference in Reporting Financial Information

This article models respondent behavior in a financial survey with a framework explicitly integrating a respondent’s knowledge of and willingness to reveal his or her financial status. Whether a respondent provides a valid answer, a “don’t know”, or a “refusal” to a financial question depends on the interaction of his or her financial knowledge and preferences regarding revealing the knowledge. Using asset response and nonresponse data from the Health and Retirement Study (2000), we found that knowledge and preferences play interrelated roles in reporting financial information, that a respondent’s age, gender, education, and race and ethnicity are important predictors of respondent behavior, and that race and ethnicity affect a respondent behavior only via their influence on preferences, while gender only via its influence on knowledge. We also found strong heterogeneity in respondents’ financial knowledge and their willingness to reveal the knowledge.

Should historic sites protection be targeted at the most famous? Evidence from a contingent valuation in Scotland

We used a contingent valuation survey of a random sample of the general public living in Scotland to estimate how willingness to pay (WTP) for the conservation of historic sites (such as castles and stone circles) varies with how well-known these sites are and whether people have visited them. Each respondent was asked to state a maximum WTP in terms of higher income taxes for the conservation of two sites, one of which was “famous” and one of which was less well-known. The hypothetical scenario involved payment to avoid future damage to each site. When observable differences in respondent characteristics are controlled for, we found no significant differences in mean WTP across sites. However, a significant effect was found for respondent familiarity with each site (in terms of recognising it on a photograph), with sites which respondents were more familiar with attracting higher WTP values. Distance effects on WTP were mixed: significant effects of distance of the site from respondents’ homes were only found for the less well-known sites, but not for famous sites. The main conclusions of the study were that (i) the Scottish general public are willing to pay for the conservation of historic sites and that (ii) such values exist as much for less well-known sites as for famous sites. This implies that public funds should not be allocated solely to conservation of the best-known sites

Attrition and Health in Ageing Studies: Evidence from ELSA and HRS

In this paper we present results of an investigation into observable characteristics associated with attrition in ELSA and the HRS, with a particular focus on whether attrition is systematically related to health outcomes and socioeconomic status (SES). Investigating the links between health and SES is one of the primary goals of the ELSA and HRS, so attrition correlated with these outcomes is a critical concern. We explored some possible reasons for these differences. Survey maturity, mobility, respondent burden, interviewer quality, and differing sampling methods all fail to account for the gap. Differential respondent incentives may play some role, but the impact of respondent incentive is difficult to test. Apparently, cultural differences between the US and Europe population in agreeing to participate and remain in scientific surveys are a more likely explanation.health, attrition

HUBUNGAN FAKTOR INTERNAL DAN EKSTERNAL PASIEN DENGAN SIS MAKANAN (STUDI PADA PASIEN RAWAT INAP NON DIIT BRSUD BANJARNEGARA)

Perbedaan hidangan merupakan salah satu evaluasi mutu pelayanan gizi dan sisa makanan pasien dapat dijadikan sebagai indikator keberhasilan pelayanan gizi Rumah Sakit. Hasil evaluasi pendahuluan diperoleh sisa makanan pasien di BRSUD Banjarnegara pada tahun 2003 sebesar 52%, dimungkinkan faktor penyebab terjadinya sisa makanan pasien berasal dari faktor menu,lingkungan dan pasien itu sendiri. Tujuan penelitian ini adalah untuk mengetahui faktor-faktor yang berhubungan dengan sisa makanan pada pasien non-diet di ruang rawat inap BRSUD Banjarnegara. Penelitian ini merupakan penelitian observasional analitik dengan desain penelitian cross sectional. Penelitian dilakukan di BRSUD Banjarnegara dengan jumlah sampel 58 orang yang dipilih secara purposive yang meliputi 8 orang di ruang Paviliun, 8 orang di ruang VIP, 7 orang di kelas 1,10 orang di kelas II dan 25 orang dirawat di kelas III. Untuk mengetahui hubungan antar variabel digunakan uji statistik korelasi Spearman dan korelasi Pearson's sesuai dengan normalitas data dari tiap - tiap variabel. Hasil penelitian menunjukkan bahwa sistim penyelenggaraan makanan di Instalasi Gizi BRSUD Banjarnegara belum memenuhi standar Pelayanan Gizi Rumah Sakit, karena belum dibentuk Tim Asuhan Gizi maupun panitia perencanaan menu dan pelayanan gizi paripurna belum dilaksanakan. Hasil analisis statistik menunjukkan adanya hubungan yang bermakna antara nafsu makan dengan sisa makanan (p=0,001); besar porsi dengan sisa makanan (p=0,011) penampilan makan dengan sisa makan (p=0,001), rasa masakan dengan sisa makanan (p=0,001), variasi menu dengan sisa makan (p=0,002);dan waktu penyajian makan dengan sisa makan (p=0,02). Upaya peningkatan kebersihan pelayanan gizi dan penurunan sisa makanan dapat dilakukan dengan peningkatan manajemen, peningkatan ketrampilan petugas pengolah, penerapan standar resep bumbu,serta penerapan jadual distribusi yang tepat. selain itu juga perlu adanya motivasi kepada pasien guna menunjang usaha penurunan sisa makanan.

ASSOCIATION BETWEEN OF INTERNAL AND EKSTERNAL FACTOR OF PATIENT AND THE LEVEL OF FOOD REMAINING (STUDY ON NON DIETERY OUT PATIENTS IN BANJARNEGARA DISTRICT GENERAL HOAPITAL) The evaluation of serving is one of evaluation of nutrient service quality and the level of food remaining is pasient that could be made as indicator of nutrition service success of hospital. Prevace survey result is gotten that of food remaining is pasient at BRSUD of Banjarnegara in 2003 is in amount of 52%, it is enabled that the couse factor of food remaining is pasient is from factor of menu,environment and pasient him self, The purpose of this research is to know of factors association with of food remaining at non dientry out patients in BRSUD of Banjarnegara. This research is analytic Observational Research Disigned by Cross Sectional Research. The research took place at BRSUD of Banjarnegara by number of sample of 58 respondent chosen purposively and covered 8 respondent in Pavilliun room, 8 respondent in VIP room, 7 respondent in frist class room, 10 respondent in the secondclass room and 25 respondent in the third class room. To know the association between used variable for statistic sperman's correlation test, based on normal data from each variable. The research result show us that food implementation system in nutrient installation of BRSUD banjarnegara did not full fill the hospital nutrient service standart yet, coused there were not the nutrient leandership team or menu planning committe and the nutrient service plenary did not do yet. The scoring result shows the performance, taste and the menu variaton are inough category. The food remaining is respondent is average 23,6%, from firts portuion. The satistics analysis result show us that there is significant relationship between appetite with the food remaining (p=0,001),a large portion with the food remaining (p=0,011); the food performance with the food remaining (p=0,001);food taste with the food remaining (p=0,001);variation of menu with the food remaining (p=0,002); serving time with the food remaining (p=0,02). The effort to increase the nutrient service success and the decrease the remaining can be done by improving management, increasing cook staff skill, application of spices and recipe standar, application od accurate distribution schedule. Besides that the motivation to patient is also needed to support the effort of decreasing the food remaining. Keyword: Internal factor, Eksternal factor, the food remaining, Hospita

The Matanuska-Susitna Borough Community Survey, 2006: A Sourcebook of Community Attitudes

The Matanuska-Susitna Borough Community Survey (Mat-Su Survey) was a cooperative effort on the part of Mat-Su College, the University of Alaska-Anchorage (UAA) and the Matanuska-Susitna Borough which asked Mat-Su Borough residents to evaluate the quality of Borough services, provide opinions about Borough decision-making, and sum up their perceptions about a range of issues relevant to the present and future of the Mat-Su community. The survey was distributed to every Borough household in the spring of 2006; a total of 2,600 were received, coded, and analyzed for the report. The Sourcebook provides detailed tabular results in six major areas: (1) evaluation of current borough services; (2) use of borough facilities; (3) life in Mat-Su neighborhoods; (4) local government access, policies, and practices; (5) higher education; and (6) respondent background information.Matanuska Susitna BoroughIntroduction / SECTION 1 DETAILED BOROUGH-WIDE RESULTS / Evaluation of Current Borough Services / Use of Borough Facilities / Life in Matanuska-Susitna Borough Neighborhoods / Local Government: Access, Policies and Practices / Higher Education / Respondent Background Information / SECTION 2: RESULTS FOR GEOGRAPHIC AREAS WITHIN THE BOROUGH / Evaluation of Current Borough Services / Use of Borough Facilities / Life in Matanuska-Susitna Borough Neighborhoods / Local Government: Access, Policies and Practices / Higher Education / Respondent Background Information / APPENDIX A: Questionnair
