Zavala-Rojas, Diana. "Measurement equivalence in multilingual comparative survey research." Doctoral thesis, Universitat Pompeu Fabra, 2016. http://hdl.handle.net/10803/399146.
Full textAbstract:
The present dissertation explores language effects in a comparative survey i.e. to what extent linguistic diversity affects equivalence in a comparative survey. This is done by studying three different dimensions on the challenges of designing a comparative multilingual survey: survey translation, linguistically diverse countries and bilingualism. Guidelines in survey translation do not link assessment criteria and measurement equivalence testing. I propose a systematic procedure to compare versions of a question in different languages before fieldwork which establishes that link. In linguistically diverse countries, survey instruments are translated into more than one language, equivalence is commonly assumed, not tested. I test for invariance distinguishing the response and cognitive processes to a survey question. Finally, I study measurement equivalence within an individual in two languages for political constructs (bilingualism), challenging current methodological approaches by bringing latent variable models.
In each dimension, findings aim to contribute to improving comparative survey methodology.Esta tesis explora los efectos del lenguaje en una encuesta comparativa: en qué medida la diversidad lingüística afecta la equivalencia de los datos mediante el estudio de tres dimensiones: la traducción de encuestas, países lingüísticamente diversos y el bilingüismo. Las directrices actuales en la traducción de encuestas no vinculan los criterios de evaluación con un test de equivalencia. Se propone un procedimiento sistemático para comparar las versiones de una pregunta que establece dicho vínculo, en diferentes idiomas antes del trabajo de campo. En países lingüísticamente diversos, el cuestionario se traduce en más de un idioma. Se realiza un test de equivalencia que permite distinguir los procesos de respuesta de los cognitivos. Finalmente, se estudia la equivalencia de conceptos políticos en dos idiomas para un individuo (bilingüismo), proponiendo un enfoque metodológico de modelos de variables latentes. Los hallazgos tienen por objeto contribuir a mejorar la metodología de encuestas en estudios comparativos.
Aquesta tesi explora els efectes del llenguatge en una enquesta comparativa: en quina mesura la diversitat lingüística afecta l'equivalència de les dades; mitjançant l'estudi de tres dimensions: la traducció d'enquestes, els països lingüísticament diversos i el bilingüisme. Les directrius actuals en la traducció d'enquestes no vinculen els criteris d'avaluació amb un test d'equivalència de mesures. Per tant, es proposa un procediment sistemàtic que estableix aquest vincle per comparar les versions d'una pregunta en diferents idiomes abans del començament del traball de camp. En països lingüísticament diversos, el qüestionari es tradueix en més d'un idioma. A la tesi, es realitza un test d'equivalència que permet diferenciar els processos de resposta dels cognitius. Finalment, s'estudia l'equivalència de conceptes polítics pel mateix individu en els seus dos idiomes (bilingüisme), mitjançant l’aplicació de models amb variables latents. Els resultats tenen per objectiu contribuir a millorar la metodologia d'enquestes en estudis comparatius.

Full textAbstract:
This paper analyzes and assesses the success and failures of the implemented methods of two mailed survey research projects conducted in post-Katrina New Orleans. Mailed survey research is an essential part of the recovery process following a major disaster in which people have been displaced. A survey can provide insight into how many residents intend to return to the area as well as resident needs and concerns. Traditional methods alone are inadequate in a post-disaster setting and supplemental measures must be taken. The collected data from a survey in this setting will be unrepresentative of the pre-disaster population. Spatial analysis of the response combined with a comparison of the collected data to known census data identifies the ways in which the data is unrepresentative. Knowledge of the data shortcomings increases its utility in planning and recovery efforts in the affected region.

Full textAbstract:
Social desirability refers to the need for social approval or acceptance (Toh, Lee, & Hu, 2006). This need results in the oft-observed human tendency to present oneself in the best possible light (Fisher, 1993), a tendency that may entail research participants giving or selecting the responses that they perceive to be most socially acceptable when completing self-report questionnaires. Whether the product of self-deception or deliberate impression management (Toh et al., 2006), the failure of participants to respond truthfully or accurately when completing self-reports can distort research results (Fisher, 1993; Schriesheim, 1979; Toh et al., 2006) and cast doubt on the validity of findings. This workshop will familiarize attendees with information on the causes of social desirability bias and simple techniques to assess and control social desirability bias in survey research.

du, Toit Linett. "A survey of the attitude towards research and research education among South African Ophthalmology trainees." Master's thesis, Faculty of Health Sciences, 2020. http://hdl.handle.net/11427/32593.
Full textAbstract:
Background Completing a research dissertation or Master of Medicine (MMed) degree during ophthalmology specialist training has now become compulsory in order to qualify as an ophthalmologist in South Africa. At a national level there is currently no co-ordinated effort to standardize research training and resources for trainees. Objectives The primary objective was to determine if South African ophthalmology trainees were interested in doing research. Secondary objectives were to determine: whether they felt that their current research training was adequate; whether a national web-based research support system would be desirable; and whether such a support platform would stimulate involvement in further research once training was completed. Methods A questionnaire was designed and anonymously completed by the trainees in each training unit in South Africa. Categorical responses were summarized using crude and weighted means with 95% confidence intervals (CI). Free text responses were analyzed thematically using an inductive approach. Results Out of 81 trainees (registrars) in South Africa at the time of the survey, 64 fully completed the questionnaire - a response rate of 79%. Seventy-two percent (95% CI 57% to 87%) of the trainees reported that they were interested in doing research. Only 28% (95% CI 18% to 41%) of respondents felt that their current research training was adequate. Ninety five percent (95% CI 86% to 99%) of trainees advocate a web-based support platform would be beneficial an eighty six percent (95% CI 74% to 93%) reported such would motivate them to continue to do research once their training was complete. The themes from the qualitative data were in keeping with the quantitative results and identified variation between training institutions in terms of available research resources, supervision and allocated time to perform research. Conclusion The trainee ophthalmologists in South Africa are interested in performing research. They feel that their current research training programs are inadequate. There is a strong need for nationally standardised research guidance to eliminate the current variation between training institutions. Guidance on dedicated time allocation to complete the research component of training should be provided by regulatory bodies. A proposed web-based support system may be a good option to standardize selected available research resources and provide equal access to all trainees nationally as well as to supplement research output during and after specialist training. Further research should address the reported lack of supervision and elucidate additional barriers to performing research in South Africa.

Full textAbstract:
The location of the available research literature and its relationship to the pedagogy of the female high voice is the subject of this thesis. The nature and pedagogy of the female high voice are described in the first four chapters. The next two chapters discuss maintenance of the voice in conventional and experimental repertoire. Chapter seven is a summary of all the pedagogy. The last chapter is a comparison of the nature and the pedagogy of the female high voice with recommended areas for further research. For instance, more information is needed to understand the acoustic factors of vibrato, singer's formant, and high energy levels in the female high voice.

Full textAbstract:
Thesis advisor: Henry BraunThis study evaluates the accuracy, precision, and stability of three different methods of cross-survey analysis in order to determine their suitability for estimating the proportions of low-incidence populations. Population parameters of size and demographic distribution are necessary for planning and policy development. The estimation of these parameters for low-incidence populations poses a number of methodological challenges. Cross-survey analysis methodologies offer an alternative to generate useful, low-incidence population estimates not readily available in today's census without conducting targeted, costly surveys to estimate group size directly. The cross-survey methods evaluated in the study are meta-analysis of complex surveys (MACS), pooled design-based cross-survey (PDCS), and Bayesian multilevel regression with post-stratification (BMRP). The accuracy and precision of these methods were assessed by comparing the estimates of the proportion of the adult Jewish population in Canada generated by each method with benchmark estimates. The stability of the estimates, in turn, was determined by cross-validating estimates obtained with data from two random stratified subsamples drawn from a large pool of US surveys. The findings of the study indicate that, under the right conditions, cross-survey methods have the potential to produce very accurate and precise estimates of low-incidence populations. The study did find that the level of accuracy and precision of these estimates varied depending on the cross-survey method used and on the conditions under which the estimates were produced. The estimates obtained with PDCS and BMRP methodologies were more accurate than the ones generated by the MACS approach. The BMRP approach generated the most accurate estimates. The pooled design-based cross-survey method generated relatively accurate estimates across all the scenarios included in the study. The precision of the estimates was found to be related to the number of surveys considered in the analyses. Overall, the findings clearly show that cross-survey analysis methods provide a useful alternative for estimation of low-incidence populations. More research is needed to fully understand the factors that affect the accuracy and precision of estimates generated by these cross-survey methods

Full textAbstract:
Land and land reform have long been contentious and highly charged topics in South Africa, with land performing the dual functions of redress for the past and development for the future. This research explores both these aspects of land, with the focus being on the impact of land receipt on household welfare and food insecurity, and social preferences for fairness and redistribution more generally. One of the main aims is to contribute to the land reform debate by providing previously-lacking quantitative evidence on the aggregate welfare outcomes of land redistribution, as well as the extent of social preferences for redistribution in the land restitution framework. In exploring these issues, the welfare outcomes of land are first explored using the National Income Dynamics Study (NIDS) data and unconditional quantile regression analysis. The focus is then narrowed to the food insecurity impact of land receipt, beginning with a methodological chapter outlining the development of a new food insecurity index applying the Alkire-Foster method of multidimensional poverty measurement (2009; 2011). This is followed by the presentation and discussion of food insecurity profiles of land beneficiary and non-beneficiary households. The new index is also used as an outcome measure in exploring the determinants of household food insecurity. These two sections again use the NIDS data. The final section shifts the emphasis from the economic welfare benefits of land redistribution to notions of fairness and social justice encapsulated by land restitution. A behavioural laboratory experiment is used to investigate social preferences for fairness, and the factors that influence redistributive inclinations, by exploring the relative weights placed on fairness considerations and self-interest, as well as the fairness ideal. The findings indicate that beneficiaries do not use the land received for productive purposes, a possible explanation for the limited economic welfare impacts of land reform that are observed. Despite this limited developmental impact, the laboratory experiment makes it clear that land reform plays an important role in addressing other needs and wants in society, particularly in respect of preferences for fairness and addressing historical injustices.

Full textAbstract:
Background There is a need for high quality research to improve perioperative patient care in Africa. The aim of this study was to understand the particular barriers to clinical research in this environment. Methods Electronic survey of African Surgical Outcomes Study (ASOS) investigators, including 29 quantitative Likert scale questions and eight qualitative questions with subsequent thematic analysis. Protocol compliant and non-compliant countries were compared according to the WHO statistics for research and development, health workforce data and world internet statistics. Results Responses were received from 134/418 invited researchers in 24/25 (96%) participating countries, and three non-participating countries. Barriers included the lack of a dedicated research team (47.7%), reliable internet access (32.6%), staff skilled in research (31.8%) and team commitment (23.8%). Protocol compliant countries had significantly more physicians per 1000 population (4 vs 0.9 p<0.01), internet penetration (38% vs 28% p=0.01) and published clinical trials (1461 vs 208 p<0.01) compared to non-compliant countries. Facilitators of research included establishing a research culture (86.9%), simple data collection tools (80%) and ASOS team interaction (77.9%). Most participants are interested in future research (93.8%). Qualitative data reiterated human resource, financial resource, and regulatory barriers. However, the desire to contribute to an African collaboration producing relevant data to improve patient outcomes, was expressed strongly by the ASOS investigators. Conclusions: Barriers to successful participation in ASOS related to resource limitations and not the motivation of clinician investigators. Practical solutions to individual barriers may increase the success of multi-centre perioperative research in Africa.

Full textAbstract:
This is a report of an investigation of aspects of preservice teachers� perceptions of teaching and learning English and mathematics and factors influencing them.
The participants of the investigation were primary preservice teachers from two tertiary institutions of Victoria, one located inner city, and the other in a regional centre. Of the 349 participants, 163 were commencing and 186 were graduating from their degrees.
Preservice teachers completed questionnaires indicating their intentions to use particular practices in their literacy and numeracy lessons. Thirty-one of the 349 surveyed voluntarily discussed key issues arising from the survey during semi-structured audiotaped sessions. Five lecturers responsible for the planning of the compulsory English and mathematics education units at both institutions were interviewed about the survey data and provided written documentation for their units as evidence of their coursework.
Data analyses indicated that preservice teachers often considered practices equally appropriate for literacy and numeracy teaching and intended to use them in similar ways. It seemed that preservice teachers enter their degrees with strong opinions about teaching and learning based not only on their recollections of experiences as learners but also from more recent relevant experiences such as their dealings with children as babysitters, tutors, and classroom helpers. They also gained knowledge about teaching contexts from their informal but regular conversations with friends and family who teach.
From the examination of the documentation for coursework and discussions with lecturers, it seemed that the content of the literacy and numeracy education units at the two institutions were similar. Overall, the data indicated that many of the preservice teachers� intentions were consistent with the intent of coursework especially when they described general teaching practices. However, in cases where practices were discipline-specific there were limited changes in preservice teachers� intentions even after completing their courses. The prospective teachers reported that they considered their recent salient experiences of teaching and their observations of teachers� practices in schools more influential than coursework.

Full textAbstract:
Water quality perception is borne out of various factors, which include taste, risk perception, water chemical and microbial parameters, trust in supplier, among others. This study addressed some of the factors that influence drinking water quality perception in the SIUE community for tap and bottled water. This was done through a survey that was delivered to the students, faculty, administration, staff, and alumni members of the university; a link to the online survey was provided via the school email, and a total number of 779 respondents participated in the survey. Some of the variables used in this study are based on general concern for taste, cost, water-chemicals (such as lead), drinking water behavior as well as demographic variables such as age, knowledge level and ethnicity. This study is based on data received from the survey conducted of the SIUE population for undergraduates, graduates, faculty, staff, administration, and alumni. Data were analyzed using several statistical methods including Spearman rank correlation coefficient and Kruskal-Wallis test. The results indicated that age and ethnicity have a significant impact on water quality perception. Drinking water behavior, age, and knowledge are well correlated in this study; therefore, they were not able to be separated.

Full textAbstract:
Information on nutrition and aging research in Brazil, Chile and Mexico was compiled. The questionnaire was adapted from one published by the United Nations Population Fund. The Pan American Health Organization (PAHO) provided the initial contact list. A search of online library databases was also done. Databases yielded a total of 149 journal articles, 21 books, 9 dissertations and 17 theses on nutrition and aging published between 1983 and 2000. The information showed that nutrition and aging is an area in the process of policy and program development and that aging is an important public health issue because of the current and projected growth of this population group. In line with the PAHO goal of improving the possibilities for healthy aging, this study may help strengthen the integration of multidisciplinary nutrition and aging research with public health policy.

Full textAbstract:
The mailed questionnaire research process developed historically as part of the survey research movement, with guidelines and models drawn from an array of scientific research methods and disciplines. Although the mailed questionnaire has become one of the most popular research instruments for obtaining data beyond the reach of the observer, the response bias generated from the generally low return rate of the mailed questionnaire survey has remained a problem. For over three decades researchers have generated a plethora of research on the effectiveness of the various aspects of the mailed questionnaire process and the resultant impact of various constructs on survey return . But despite these efforts, researchers have not succeeded collectively in producing a clear, compelling, or consistent set of principles that, if followed, will produce high response rates in mailed questionnaire research . With the certainty that more knowledge and constructs will be generated in all areas of the mailed questionnaire process, scholars have issued a call for a viable theory to direct future research efforts on response rates . Therefore, the purpose of this study was to address that need . The dissertation research reported in this paper accomplished five major objectives. It (a) developed an interdisciplinary theoretical framework for the mailed questionnaire process; (b) identified 13 determinants of response costs in the mailed questionnaire process; (c) proposed immediacy and salience as the most significant determinant variables of response rates, from a synthesis of the research literature with the theoretical framework; (d) proposed a theory and theoretical model that explain and illustrate the interaction of immediacy and salience in determining response rate levels; and (e) recommended a method for testing the proposed theory and for utilizing the proposed theory to achieve high response rates in future mailed questionnaire studies.

Full textAbstract:
With an increasing reliance on satisfaction exit surveys to measure how university alumni qualify their experiences during their degree program, it is uncertain whether satisfaction is sufficiently salient, for some alumni, to generate distinguishable satisfaction scores between respondents and nonrespondents.
This thesis explores whether, to what extent, and why nonresponse to student satisfaction surveys makes any difference to our understanding of student university experiences. A modified version of Michalos’ multiple discrepancies theory was utilized as the conceptual framework to ascertain which aspects of the student experience are likely to be nonignorable, and which are likely to be ignorable. In recognition of the hierarchical structure of educational organizations, the thesis explores the impact of alumnus and departmental characteristics on nonresponse error. The impact of survey protocols on nonresponse error is also explored.
Nonignorable nonresponse was investigated using a multi-method approach. Quantitative analyses were based on a combined dataset gathered by the Graduate Student Exit Survey, conducted at each convocation over a period of three years. These data were compared against basic enrolment variables, departmental characteristics, and the public version of Statistic Canada’s National Graduate Survey. Analyses were conducted to ascertain whether nonresponse is nonignorable at the descriptive and analytical levels (form resistant hypothesis). Qualitative analyses were based on nine cognitive interviews from both recent and soon-to-be alumni.
Results were severely weakened by external and internal validity issues, and are therefore indicative but not conclusive. The findings suggest that nonrespondents are different from respondents, satisfaction intensity is weakly related to response rate, and that the ensuing nonresponse error in the marginals can be classified, albeit not fully, as missing at random. The form resistant hypothesis remains unaffected for variations in response rates. Cognitive interviews confirmed the presence of measurement errors which further weakens the case for nonignorability. An inadvertent methodological alignment of response pool homogeneity, a misspecified conceptual model, measurement error (dilution), and a non-salient, bureaucratically-inspired, survey topic are proposed as the likely reasons for the findings of ignorability. Methodological and organizational implications of the results are also discussed.

The main purpose of survey is to let the researcher know valid information for a certain time. Survey can transform some incidents and experiences into forms that can be analysed. The main purpose of online survey is to improve the complicated workflow of the traditional questionnaire, lower costs and improve the efficiency of retrieving. However, after using network technology, which online survey advantage can be increased? How to build convenient online survey service system? The online survey service system at present seems not to have a perfect mechanism. A lot of investigation results of relevant fields are often independent.It is unable to consult each other, turn into the questionnaire investigation database. This research will plan functions of internet questionnaire service and design an online survey service system (Internet Survey Service System, ISSS, I3S). Expect to improve the procedure of online survey and the design process of the questionnaire and save the time of the investigation sparingly, increase the integrality of the online survey.

With the development of economy and the progress of society, not only the government but enterprise holds a wide range of large-scaled surveys owing to various needs. For a large-scaled survey, there are often too many questions in a questionnaire. When an interviewee is filling out the questionnaire, he might give you an arbitrary answer because he has no patience to finish it. Therefore, a large-scaled survey will be implemented by dividing one large-scaled survey questionnaire into several small-scaled survey questionnaires to prevent the situation mentioned above. This research focuses on how to combine several small-scaled survey data sets into one complete data set. By analyzing the complete data set, we can obtain more information about interviewees. In this research, we propose a new data imputation method which can be used to combine two small-scaled survey data into one complete data set. In this research, we also apply out method to real data set, named Taiwan Social Change Survey, which is conducted for around 20 years in Taiwan. We choose two independent questionnaire surveys in 2004 to justify our method. The first one is about religion and culture. The left one is about citizenship. At the first step of merging, we impute the missing value of two small-scaled survey data sets, individually. Second, impute those questions which the interviewee didn’t answer. After data merging, we also compare the distributions of questions between former and latter imputations. It shows no difference in frequency between the two imputations. Hence, it’s reasonable to use the new imputation method to combine these two small-scaled data sets.

Taiwan is much higher than the proportion of existing buildings newly constructed buildings. Saturated due to urban land use, national lifestyle changes and other reasons. In recent years, the demand for new buildings, a decreasing trend. It has entered the era of building repairs. Deterioration survey of existing buildings in Taiwan still no more perfect process and methods. In this study, both the deterioration of the building shell to explore methods of investigation, expectations can survey the current domestic suggest ways of existing buildings, the study includes： 1. Clarify the existing building shell deterioration in Taiwan survey methodology and framework. 2. The deterioration of the building shell for the different behavior of the proposed survey methodology proposed. Scope of this study is the shell of the building external walls, arcade and foyer, roof This three projects, research methods to collect first foreign literature to enrich the building deteriorated conduct of investigations required at all stages of the relevant knowledge. Secondly questionnaire developed plans to choose a suitable expert questionnaire survey, building survey to understand the current survey methodology experts; longer second stage of the survey questionnaire interview survey, sorting out the current situation in Taiwan deterioration of the building envelope survey methods. Finally, the second stage after the interview survey results are summarized and foreign literature review to compare, analyze and make the difference between the current deterioration of the proposed survey methodology. There are three conclusions： Firstly, Questionnaire compiled by the experts, that the external walls and roof of the Taiwan investigation methods further into space, greater use of aids to help investigate; while the arcade and the main hall is only a visual survey. Therefore, for Taiwan's existing external walls and roof of the building shell survey methodology, survey of selected objects, the status of the second stage of investigation interviews. Secondly, The use of expert survey results, the development of the second stage interview questions for the second interview, the focus of the second phase of survey content objects in the understanding of the actual conduct interviews with the roof deterioration of exterior investigation processes and situations. 1. Deteriorated exterior survey process once dominated the time of diagnosis by visual survey, The main purpose is to conduct on-site investigations and record observations, secondary diagnosis is a more comprehensive detailed investigation, Generally comprehensive visual survey method is the most widely used. 2. Roof deterioration investigation focused on leaky roofs and waterproofing, Once dominated the time of diagnosis by visual survey, Secondary diagnosis of the actual test will be conducted. Thirdly, Then compiled their findings after interviews and literature review conducted with the Japanese compiled comparison and found deterioration of Taiwan's current status in the survey operations, the still inadequate, so for different scenarios of degradation processes in the investigation, given appropriate survey Methodology recommendations. Investigation wall cracks, use crack measuring ruler, measuring needles and hand-held microscope, ultrasound imaging detection and infrared sensors. Investigation wall tiles falling, Recommend consultation with the hammer, ultrasonic detection and imaging infrared sensor. Survey leaking roof, Ultrasonic detection method can be recommended.

This article is mainly based on the concept of the "intelligence decision-making" system model, taking the purpose of sampling and interviewing the leisure activists with the decision-making background. Then from the interview, we summarize, analyze and verify whether the system model of "intelligence decision" is suitable for the decision-making of leisure activities. According to the interview, leisure behavior is a kind of dynamic decision-making, and he must find satisfactory leisure activities through continuous information feedback. Therefore, in the process of systematic decision-making, the decision-making process of leisure behavior still can not be separated from the model structure of "intelligence decision".

Marine magnetic survey is broadly applied to detect ferrous material on seafloor. After processing, the measured value can be transformed to magnetic anomaly map, researcher can locate ferrous target by means of analyzing magnetic features that generated by the ferrous target. Locating electric cables on seafloor, detecting underwater artificial target, searching ship wreckage, studying magnetic contamination and archaeological research are some examples of applications about marine magnetic survey. In this research, we had G880 cesium optical pumping magnetometer measuring total magnetic field, the length of survey ship is about 10 meters. To avoid influence of magnetic disturb, the distance between the ship and magnetometer remained 20 to 30 meters. The nearby Center Weather Bureau magnetic observatory stations were chosen for magnetic ground reference stations. Different directions of geomagnetism and various shape of ferrous targets change magnetic anomaly features. The most classical magnetic features are dipole mode and pipeline mode. In this dissertation, two marine magnetic survey case are pointed out to study and discuss two distinct magnetic features respectively. The result of electric cable between Liuqiu and Taiwan survey show us dipole magnetic features, and the magnetic anomalies are quite obvious. After data processing, the gridded magnetic map present that the magnetism cables generate is similar to which a linear magnet does, in addition, direction of magnetism is along the cables. Due to the giant volume, the cables are highly magnetized, the maximum of magnetic anomalies even reached 60 nT. The predicted location of cables is close to the actual one. The result of lomgmen magnetic survey present dipole anomaly feature. The gridded magnetic map points out that there are two magnetic anomalies in the survey area; one is in the north-eastern area, the other is in the west–southern area. In the same geomagnetism field, these two values and directions of anomalies are different. The research conclude that the fact is highly relevant to the depth and heading of the target. The wavelength of anomalies is a function of the distances between targets and magnetometer, and the heading of magnetic source could change the direction of its anomalies. Therefore, the researcher could interpret depth and heading of the source by studying the magnetic field above it. The side scan image in the same survey area prove the accuracy of the interpretation of magnetic survey. In order to improve the accuracy, we discussed how headings of ship could change the quality of measured data. According to the basic theory of magnetometer, the sensor can not collect data, when the angle between geomagnetism and magnetometer fall into “dead zone”. After the experiment, the magnetometer would have the best performance in measuring when it was set to both 0 degree in rotation and tilt angle. ( The inclination and declination of geomagnetism in Taiwan area is -4.09° and 37.1° respectively. ) Marine survey usually comprises of multiple measuring methods, so the integration between different kinds of information is important. For instance, combined with side scan image, the magnetic survey can pick out ferrous targets of interest, and present the heading, depth, and roughly-measuring weight of ferrous material by studying the magnetic anomalies.Based on the several cases and study in this dissertation, we could conclude that marine magnetic survey is able to apply to maritime research widely and present convinced result in detecting and locating ferrous target. To ensure the accuracy, controlling magnetic noise, adjusting magnetometer correctly, and enhancing location system is necessary in marine magnetic survey.

Internet has been one of important interactive and commercial platform. Web survey tool becomes getting popular following traditional survey tools by paper-pen, telephone and FAX, etc. Some studies had proved that web survey has much better efficiency on sending and receiving survey form, and after work of analysis, but just a few studies made for the topic of web survey effectiveness. Web survey tool can make varied design like automatic re-check mechanism that is not any else can do. It’s no doubt about automatic re-check mechanism can make sure fill-in quality but such questionnaire with re-check normally put with privacy question, so that it reduces fill-in intention to people, and it reflects to lower reply and lower fill-in rate on web survey type of questionnaire. It also makes most of web survey quality being challenged on its effectiveness. This is the first study made by the experimental research for web survey quality related in Taiwan, R.O.C. We focus on the influence of automatic re-check mechanism to web survey effectiveness. We conducted 160 students in BA department of NCU and made 5 different questionnaires for sending total 160 pcs of electronic questionnaire to each student, and we compared the result of both fill-in rate and response rate for these questionnaires by designed 5 independent variables --- Re-check, Privacy protecting declaration, Social goodness behavior and Incentive. We found that it made lower response rate when the questionnaire is with automatic re-check mechanism; in addition, it increased fill-in rate of the questionnaire not only for those privacy questions with re-check mechanism but also for those general questions without putting re-check mechanism.

As the increasing of Internet coverage, many researches use Web as platform to collect data. Sampling in online survey requires much less time and effort than traditional (face-to-face, telephone etc.) method. However, there is no specific distribution of Internet users. To solve this problem, adding limitation factors in sampling model may keep selecting samples approaching population and increase validity and reliability. There are few researches about sampling method improvement, therefore; before we find better approach, this research classifies survey topic into six categories. Through proposition approach, this research gives some advice about contents. Online survey topics through those contents extended from six categories will increase validity.

Taiwan’s super senior society is coming soon,silver light economy takes off, how to master the demand of the silver-haired people will drive a new wave of industrial development in Taiwan. At the end of 2017, Long Yi Research, a subsidiary of the Zhirong Foundation, launched a two-month, full-scale “Le Le Live Everyone – Future Elderly Needs Survey”, collect nearly 70,000 big data sources and disclose them to the public. The purpose of this study is to use the secondary information of this disclosure to explore the real needs of Taiwanese seniors and the way they really want to solve problems, reference for companies to design quality products and innovative services for the elderly. From the research of nearly 70,000 pieces of information, the first two items of life that Taiwans senior citizens care about most are "self-care life" and "eat healthy nutrition." The most troublesome thing in "self-care life" is that "the old worry about forgetting to turn off the fire and shutting down the gas, and it is afraid of accidents" and "the old age make body inflexible, and it is impossible to climb up and contribute to the family." The two major pain points for the elderly to " eat healthy nutrition " in their daily needs are "the fruits and vegetables do not show any pesticide pollution, and they are not safe to eat" and "one or two people can only eat easily and are difficult to nutritional balance." The researchers proposed solutions for the first two life needs of the elderly. The solution to the pain of " self-care life " is " the fire can be turned off remotely ", "automatically turn off the fire at the time", "simple home repair service", "the building management company has repair service".The life trouble of "eat healthy nutrition", the proposed solutions such as "cheap organic fruits and vegetables", "reliable agricultural product safety stamps", "community opening a eating-together restaurant" and "small amount of various food ingredients". Research results can provide industry in the needs of old age, planning and design related product and service models in order to meet the real needs of the people and create business opportunities. Keywords: Silver economy, Industrial development, Pain points, Secondary data analysis

The purpose of this study is four folds. First, to discover the most popular flute method books for beginners; Second, to determine the most popular contents in flute teaching and to determine the difficulties encountered by flute teachers; Third, to explore the flute teachers’ opinions and attitudes toward graded flute examination; Fourth, to investigate the differences between flute teachers’ background variables and their teaching contents, teaching difficulties and attitudes toward graded flute examination. This study is a Survey Research. A questionnaire was designed to assess the current condition of flute studio teaching in Taipei, Taichung, Tainan and Kaohsiung. A total of 174 questionnaires were collected. The return rate was 67.42％. The data was analyzed with Descriptive Statistics such as percentage, mean and standard deviation. One way ANOVA was used to determine the differences between flute method books for beginners, teaching contents, and difficulties encountered by flute teachers, and flute teachers’ opinions and attitudes toward graded flute examination. In order to verify questions found in the questionnaire and gain deeper insight, ten flute teachers were interviewed by the researcher. The findings were as follows: 1. The most popular teaching methods for beginners are as follows: (1) Method books, (2) Music Collections, (3) Exercises, (4) Duets, (5) Self-developed materials. 2. The most important teaching contents are as follows: (1) posture, (2) music fundamentals, (3) breathing, (4) tone development, (5) timbres, (6) intonation, (7) sight reading, (8) aural training, (9) memorization. 3. The problems flute beginners encountered most are as follows: (1) timbres, (2) breath control, (3) fingering, (4) tonguing, (5) posture, (6) intonation, (7) embouchure. 4. Most flute teachers have positive attitudes and experiences in tutoring students in participation of graded flute examination. 5. There are statistically significant differences between years of teaching experiences and self-developed materials, flute background and exercises, self-developed materials. 6. There are statistically significant differences between intonation and years of teaching, memorization and flute background. 7. There are statistically significant differences on contents of grading examination, flute teachers’ satisfaction levels on grading examination, the criteria on choosing systems, approval of grading examination, and years of teaching experiences. For future researchers, several recommendations were drawn from this study: (1) Follow-up researches can enlarge the scale of the study to cover entire Taiwan or college flute teachers. (2) Follow-up researchers can conduct qualitative researches to gain more insight about flute teaching. (3) Future researchers can explore other variables such as age and sex.

Full textAbstract:
In survey research, researchers often add up a finite number of binary responses to form an index of some political attitude or behavior, such as political knowledge and political participation. Indices of this sort are called grouped binary variables in political science research; they comprise finite and countable binary items that take on only integer values ranging from zero to the total number of survey items. Commonly-used distributions for modeling these kinds of indices are the binomial, beta binomial, and extended beta binomial distributions. But whether these distributions are appropriate depends on the assumptions that the binary responses are identically and independently distributed Bernoulli random variables. If these assumptions are violated, the binomial, beta binomial, and extended beta binomial models are rendered questionable, and it may be more useful to turn to other distributions of sums of Bernoulli variables, called generalized binomial distributions.
To facilitate the use of generalized binomial distributions in political science research, this report is a review of the various probability distributions of grouped binary variables. This report clarifies the nature of the distributions of sums of Bernoulli variables in survey research by considering whether the Bernoulli variables are independently and/or identically distributed, whether there is heterogeneity across survey items and/or across respondents, and the consequences of these considerations for the relative dispersion of each generalized binomial distribution.text

The research aims to measure current health literacy of kindergarten children’s parents, explore different background variables affecting their health literacy levels and discuss related issues. The study population consisted of parents of kindergarten children in southern Taiwan. The purposive sampling method was adopted. The research studied parents of young students in seven private kindergartens in Kaohsiung and Tainan. Some of these kindergartens adopted vegetarian diets, while others did not. The questionnaire, as the research tool, was adapted from the “Survey on Health Literacy of Kindergarten Children’s Parents.” A total of 600 questionnaires were distributed to the parents and 530 of them were collected. 9 of them were invalid due to incomplete answers, and the 521 valid copies accounted for 86.8 % of all questionnaires distributed. The data analysis adopted several statistical methods, including average method, standard deviation, t-test, one-way ANOVA, Pearson's product-moment correlation and step-wise regression analysis. The research has reached the following conclusions: 1. The overall health literacy level of the young children’s parents was good, while their functional health literacy level was highest and their critical health literacy level was the lowest. 2. Health literacy levels of the young children’s parents were affected by the parents’ education levels, household income levels and young children’s birth orders. The higher the parents’ education level and their household income were, the higher their health literacy level was. In addition, parents of first child had higher health literacy. 3. Functional health literacy levels of young children’s parents were affected by their ages; the older the parents were, the higher their functional health literacy level was. 4. Health literacy levels of young children’s parents were also affected by their acceptance of vegetarian diets; the more the parents accept the health policy of vegetarian diets, the higher their health literacy was. 5. Education level, acceptance of vegetarian diet, household income, child’s birth order and age were indicators for health literacy level of the young children’s parents. Some suggestions were provided based on the findings and results of the empirical study in the last part of the paper for the reference of government education agencies, parents of young children and future academic researchers.
