The current study expands upon existing developmental research on marital attitude change by examining how attitudes toward marriage and long-term relationships may vary across emerging adulthood. Utilizing five waves of data from the Center on Young Adult Health and Development’s College Life Study, discrete-time survival analysis and latent basis growth curve analysis are employed to assess the change—and predictors of such change—in three measures of relationship attitudes (desire for marriage, desire for long-term relationships, and importance of marriage and long-term relationships) of over 900 college students. Results indicate positive change in all three measures of attitudes, with most emerging adults desiring and placing importance on marriage and long-term relationships from the very beginning of college. Predictors of attitude change included sex, race, experience of parental death, student status, educational aspirations, and total number of sex partners. Results suggest a need for more longitudinal research in this area.

Problem: This study aims to examine the factors that influence the individual's different choice of risk level. Demographic characteristics are the underlying factors being analyzed in the study with a special emphasis on geographic factors – this in order to analyze and explain the Swedish individual’s approach to risk. Based on certified private advisers’ perspective, the study will also examine their approach to manage individuals’ risk. Purpose: Studying the differences in risk aversion among individuals when making investment decisions, based on demographic factors and geographical areas. Theory: The essay’s theoretical framework deals with theories covering behavioral finance, the risk appetite development in individuals at a demographic and geographic way, and an overview of previous research on the subject. Method: We conducted a quantitative study in which 340 respondents were asked to answer a survey. We also interviewed three certified counselors from three different banks in Sweden. Conclusions: In line with behavioral finance theory, people are not rational when making investment decisions. The study concludes that people in big cities tend to be more risk-averse than people in smaller cities. Sex is shown to be a differentiating factor with men having a higher risk-aversion than women. A higher income and level of education leads to a higher risk attitude and marital status affects the risk appetite where a married person has a higher risk appetite than a person who is single. Age and education, showed to have no relationship to the level of risk.

Background: Research showed that older people's sexual health is not addressed adequately in the health sector. It is a subject that is very limited or non-existent during basic training for nursing students. Older peoples sexually health has improved and hence there will be an even more important area for the nurse, who is responsible for the patient's health. Existing prejudices about sexuality of elderly people means that more knowledge is needed. Aim: The aim was to describe: 1. elderly person's experience of their sexual health and the health care receptions. 2. health care workers' attitudes towards older patients' sexual health. Method: A literature overview. Four qualitative and six quantitative studies between the years 2000- 2015 were analyzed. Results: Three main themes were identified; older people's experiences, that showed that older patients are healthier and more sexually active than before. The second main theme; health care workers experience of older people's sexual health showed that the patient's greatest obstacles to exercising their sexuality is the lack of private spaces. The nurse usually had a negative attitude to the elderly persons' sexual health, which could be due to nurses' ignorance and that sexuality is a sensitive subject. The third theme showed factors which affect sexual health in elderly. Conclusion: More information is needed about the elderly person's sexual health for patients and more training in nursing. Many older suppress their sexuality because of different standards and taboos in society, which may lead to unnecessary suffering.

ITC/USA 2006 Conference Proceedings / The Forty-Second Annual International Telemetering Conference and Technical Exhibition / October 23-26, 2006 / Town and Country Resort & Convention Center, San Diego, California / For the final evaluation of a GPS attitude determination algorithm, it was determined its true performance in terms of accuracy, reliability and dynamic response. To accomplish that, a flight test campaign was carried out to validate the attitude determination algorithm. In this phase, the measured aircraft attitude was compared to a reference attitude, to allow the determination of the errors. The system was built using non-dedicated airborne GPS receivers, and a complete Flight Tests Instrumentation (FTI) System. The flight test campaign was carried out at the Brazilian’s Flight Test Group T-25C 1956 Basic Trainer aircraft. The performance and accuracy of the system is demonstrated under static and dynamics tests profiles, which are fully compliant with the Federal Aviation Administration (FAA) Advisory Circular (AC) 25-7A. Dynamic response of the system is evaluated.

This thesis is concerned with determining the orientation of small Unmanned Aerial Vehicles(UAVs). To make commercial use of these aircraft in aerial surveying markets their attitude needs to be determined accurately and precisely throughout a survey flight. Traditionally inertial sensors have been used on larger aircraft to estimate both position and orientation in combination with Global Navigation Satellite Systems (GNSS). High quality inertial sensors have many downsides when used on the small UAV. They are expensive, power hungry and often heavy. Inertial sensors are vulnerable to vibration, high acceleration, high rotation rate and jerk. All of these are present on the small UAV. This thesis identifies GNSS attitude determination as a potentially suitable alternative to inertial techniques. Carrier phase GNSS attitude determination uses three or more GNSS receivers with antennas separated by a short baseline to estimate the orientation of the UAV. This technique offers low cost, high accuracy and drift-free attitude estimates. To be successfully used it requires removal of the biases present in the received GNSS signals and estimation of the integer cycle ambiguity present in the carrier phase measurement. This thesis presents and examines the state of the art techniques for removing these biases and estimating an integer cycle ambiguity using a priori measurement of the interantenna distance. In this work a novel method is developed which uses this a priori baseline measurement to validate estimates of the carrier phase ambiguities. In order to test these methods data has been gathered using low cost, commercially available GNSS receivers and antennas. This is the first work in which modern, low cost, GNSS equipment has been tested for use in attitude determination. It is found that the state of the art carrier phase GNSS attitude determination methods can provide an accurate attitude estimate for every set of measurements from the GNSS receivers. However, a real UAV flight indicates that the low cost GNSS equipment does not track the GNSS signals throughout the flight. Signal outages, cycle slips and half cycle ambiguous carrier phase measurements occur due to rapid UAV manoeuvres. Having identified this problem this work goes on to replicate and quantify it through the use of a GNSS hardware simulator. Algorithms are then devised to increase the availability of the GNSS attitude solution throughout the tracking difficulties. Complete GNSS signal tracking failures are overcome through the innovative use of kinematic and dynamic attitude models. Both types of model give an attitude solution throughout GNSS signal tracking problems without adding significant cost or weight to the system. When tracking of the GNSS carrier phase signal is possible, novel use of the carrier phase triple difference observable allows the attitude rate to be estimated even when the carrier phase measurements are half cycle ambiguous. It is shown that integer and half integer cycle slips can be removed from the measurement through the combination of the modelling and triple difference techniques. The attitude output of both modelling and triple difference methods is used to resolve half cycle ambiguities and make full use of half cycle ambiguous data where previously it could not have been used. Success rates of up to 99.6% have been achieved for half cycle ambiguity resolution. As a result precise and accurate GNSS attitude solutions are available at nearly every epoch for which a carrier phase measurement is output by the GNSS receivers. When no measurement is available the attitude solution gracefully degrades over time. This work makes reliable, accurate, low cost attitude determination possible on mini-UAVs.

Propositional attitudes, states like believing, desiring, intending, etc., have played a central role in the articulation of many of our major theories, both in philosophy and the social sciences. Until relatively recently, psychology was a prominent entry on the list of social sciences in which propositional attitudes occupied center stage. In this century, though, behaviorists began to make a self-conscious effort to expunge "mentalistic" notions from their theorizing. Behaviorism has failed. Psychology therefore is again experiencing "formative years," and two themes have caught the interest of philosophers. The first is that psychological theories evidently must exploit a vast array of relations obtaining among internal states. The second is that the use of mentalistic idioms seems to be explicit again in much of current theorizing. These two observations have led philosophers to wonder about the probable as well as the proper role of propositional attitudes in future psychological theories. Some philosophers wonder, in particular, about the role of the contents of propositional attitudes in the forthcoming theories. Their strategy is in part to discern what sorts of theory psychologists now will want to construct, and then discern what role propositional attitude contents might play in theories of those sorts. I consider here two sorts of theory, what I call minimal functional theories and what is known as propositional attitude psychology. I outline these two kinds of theory, and show how each defines a role for contents. Contents are ultimately eliminable in minimal functional theories. Although they play an apparently ineliminable role in propositional attitude psychology, they do so at an apparent cost. Propositional attitude psychology does not seem to accommodate a certain methodological principle, a principle of individualism in psychology, which is endorsed even by some of the philosophers most enamored of the approach. Such philosophers have two options: they can attempt to show that the conflict between the approach and the principle is not genuine, or they can reject the principle. I argue that the conflict is real, and recommend a qualified rejections of the principle.
