Offenders who target children are a negative phenomenon in our society. These offenders are often seen as the worst of the worst of criminals and are therefore a priority for investigators trying to solve these crimes as fast as possible. The purpose of this thesis is to see if there are common denominators among these offenders in their modus operandi (MO) and their spatial patterns. If similar patterns emerge amongst these offenders, that would be of investigative importance for those who work with crimes against children. In Study I, a group of child molesters and their MO were studied in order to see how they found their victims and where they committed their crimes. The results were consistent with previous studies on child molesters in that they all committed their crimes at home or close to their homes. In Study II, a geographical profiling tool was tested in order to see if such a program could be used to find an offender who made obscene phone calls (OPC) to children. The results showed that the geographical software based on spatial behaviour, was able to narrow down the search area in which the offender actually lived when he committed his crimes. In Study III, the focus was on the potential witnesses/victims and how much a child could remember correctly of a staged event simulating a potential child molester looking for new victims. The results showed that the children’s event memory were comparable with an adult control group. The combined results could be summarized as follows: offenders who target children usually commit their crimes at home or close to home (or base), they tend to lure children to go with them by using bribes or the recruitment of former victims. Girls seem to be the preferred sex over boys. Children could be used as accurate witnesses in these types of crimes.

The purpose of this study is to illuminate the role, the function, and the ironic outcome of the Victory in Vietnam Committee's campaign pamphlet to recall Senator Frank Church of Idaho in 1967. The VVC's political strategy was to build credibility with the media through the recall pamphlet. The analysis of the recall pamphlet shows the failure of the Victory in Vietnam Committee to adapt to the intended audience, the media. The pamphlet is further evaluated in the context of manichean rhetoric to highlight the unethical use of credibility building techniques and the ultimate goal of the VVC to stifle Church's dissent with respect to the Vietnam War. The irony of the Victory in Vietnam Committee's explanatory pamphlet is that instead of helping to oust Church by exposing his faults, it caused the downfall of the Victory in Vietnam Committee. / Graduation date: 1992

In a world dominated by temporal order, memory capable of processing, encoding and subsequently recalling ordered information is very important. Over the decades this memory, known as serial memory, has been extensively studied, and its effects are well known. Many models have also been developed, and while these models are able to reproduce the behavioural effects observed in human recall studies, they are not always implementable in a biologically plausible manner. This thesis presents the Ordinal Serial Encoding model, a model inspired by biology and designed with a broader view of general cognitive architectures in mind. This model has the advantage of simplicity, and we show how neuro-plausibility can be achieved by employing the principles of the Neural Engineering Framework in the model’s design. Additionally, we demonstrate that not only is the model able to closely mirror human performance in various recall tasks, but the behaviour of the model is itself a consequence of the underlying neural architecture.

Objectives: The aim of the two exploratory studies presented here, was to investigate expert-novice cognitive performance in the field of dietetic counseling. More specifically, the purpose was to characterize the knowledge used and the cognitive reasoning strategies of expert, intermediate and novice dietitians during their assessment of clinical vignettes of simulated dyslipidemia cases. Background: Since no studies have been conducted on the expert-novice differences in knowledge utilization and reasoning in the field of dietetics, literature from various domains looking at expert-novice decision-making was used to guide the studies presented here. Previous expert-novice research in aspects of health such as counseling and diagnostic reasoning among physicians and nurses has found differences between in the way experts extract and apply knowledge during reasoning. In addition, various studies illustrate an intermediate effect, where generalist performance is somewhat poorer than that of experts and novices. Methods: The verbal protocols of expert (n=4), generalist (n=4), and novice (n=4) dietitians were analyzed, using propositional analysis. Semantic networks were generated, and used to compare reasoning processes to a reference model developed from an existing Dyslipidemia care map by Brauer et al, (2007, 2009). Detailed analysis was conducted on individual networks in an effort to obtain better understanding of cue utilization, concept usage, and overall cohesiveness during reasoning. Results: The results of the first study indicate no statistical differences in reasoning between novices, generalist and experts with regards to recalls and inferences. Interesting findings in the study also suggest that discussions of the terms “dietary fat” and “cholesterol” by individuals in each level of expertise had qualitative differences. This may be reflective of the information provided in the case scenearios to each participating dietitian. Furthermore, contrary to previous studies in expert-novice reasoning, an intermediate effect was not evident. The results of the second study show a statistical difference in data driven (forward) reasoning between experts and novices. There was no statistical difference in hypothesis driven (backward) reasoning between groups. The reasoning networks of experts appear to reveal more concise explanations of important aspects related to dyslipidemia counseling. Reasoning patterns of the expert dietitians appear more coherent, although there was no statistical difference in the length or number of reasoning chains between groups. With previous research focusing on diagnostic reasoning rather than counseling, this finding may be a result of the nature of the underlying task. Conclusion: The studies presented here serve as a basis for future expert-novice research in the field of dietetics. The exploration of individual verbal protocols to identify characteristics of dietitians of various levels of expertise, can provide insight into the way knowledge is used and applied during diet counseling. Subsequent research can focus on randomized sample selection, with case scenarios as a constant, in order to obtain results that can be generalized to the greater dietitian population.

Marketers have always been looking for alternative ways to reach the target population with their messages. One approach that has grown the last decades is product placement that has become a large arena for companies to involve in their marketing communication. It has been shown that people tend to dislike traditional advertisement such as commercial brakes in TV and tries to avoid it by switching channel. Since product placement is a type of advertisement that is embedded in a movie or TV-show and cannot be zapped away without missing the story of the movie or TV-show, it is a good opportunity to reach out with a company’s message. Several studies have been done in the field of mapping the attitudes towards product placement but no research has been done with the Swedish audience in focus. Therefore the purpose of this thesis is: “…to investigate what attitudes the Swedish audience has towards product placements in Movies and TV-shows”, which will lead to a greater knowledge for Swedish marketing managers about the attitudes towards product placement in Sweden. This thesis is a quantitative study with a descriptive single cross-sectional design. The data was retrieved through a questionnaire online. The sample frame was generation Y which is people that are between the ages 18-35. The study showed that the general attitude towards product placement is positive for the Swedish audience. When it comes to the different dimensions of product placement; visual-only, audio-only and a combination audio-visual it is shown that the visual placements is seen as the most positive way to place a product in a movie or a TV-show. It could also be seen several similarities with previous studies that prominent placement has a lower attitude while a subtle placements has a more positive attitude.

Den här studien grundar sig på skillnader mellan återgivning av ord, sorterade efter semantiska kategorier, i förhållanden med rent tal och maskerat tal. 32 personer deltog i studien där de först blev visuellt presenterade för en lista med 15 semantiska ord som skulle memoreras och sedan återges i fri ordning i två olika betingelser av bakgrundsljud, tal och maskerat tal. Utifrån tidigare studier utformades studiens hypoteser; vid återgivningen ökar antalet visuellt presenterade ord när bakgrundstalet maskeras av ett brus jämfört med när bakgrundstalet spelas upp utan maskering. Antalet auditivt presenterade ord som återges minskar när bakgrundstalet maskeras av ett brus jämfört med när bakgrundstalet spelas upp utan maskering. Resultaten gav stöd åt hypotesen att försökspersonerna återgav fler visuellt presenterade ord när bakgrundstalet maskerades av ett brus. Resultatet gav stöd åt hypotesen att försökspersonen återgav färre auditivt presenterade ord när bakgrundstalet maskerades av ett brus. / This study examined free recall performance in two acoustic conditions, speech and masked speech. Thirty-two students participated in the study. They were visually presented to word lists that were constructed by semantic similarity. After presentation the participants were instructed to recall as many words as possible in free order. The recall session occurred in the two different speech conditions. Based on earlier studies two hypotheses were stated; when the background speech were mixed with masking noise, recall performance of correct words would increase compared to the speech condition. It was also assumed that the masking noise would decrease the number of intrusions from the speech, compare with the number of intrusions made in the unmasked speech condition. The result gave support to the hypothesis that number of correct words increases in masked speech and the number of intrusions decreases in masked speech.

Individual differences on complex memory spans predict a variety of higher-order cognitive tasks (e.g. reading comprehension, reasoning, following direction) as well as low-level attention tasks (e.g. Stroop, dichotic listening, antisaccade). The current study attempted to better determine the role of individual differences in complex memory span and episodic retrieval. Specifically, two experiments explored the possibility that individual differences in complex memory span reflect differences in the ability to successfully retrieve items from secondary memory via a cue-dependent search process. High and low complex span participants were tested in delayed (Experiment 1) and continuous distractor (Experiment 2) free recall with varying list-lengths. Across both experiments low spans recalled fewer items than high spans, recalled more previous list intrusions than high spans, and recalled at a slower rate than high spans. It is argued that low spans search through a larger set of items than high spans and, thus low spans episodic retrieval deficits are associated with an inability to use cues to guide a search and retrieval process of secondary memory. Implications for dual-component models of memory are discussed.

A global outbreak of a new strain of H1N1 influenza virus caused the 2009 flu pandemic. Taiwan was one of the 12 countries in the world capable of producing H1N1 vaccine domestically. The domestic vaccine manufactured by Adimmune Corporation proved to be safe and effective. However, the public opinion generally criticized negatively toward this H1N1 prevention work. This study explored the various entities and relations surrounding the prevention. The first experiment looked into people¡¦s recall toward government¡¦s promotion. This experiment used EyeLink to track subjects¡¦ eye movements on the promotional posters. The data showed the correlation between eye movement and recall, as well as the amount of information received by the subjects. The second experiment looked into people¡¦s decision toward H1N1 prevention. This experiment constructed an AHP model to study the problem. The subjects from various fields answered their view toward H1N1 prevention alternatives, and reported the actual inoculation rate of H1N1 vaccine. The goal aimed to choose a prevention method. The criteria included convenience, confidence, safety, and comfort. The alternatives included vaccination, medication, and sanitation. The experiment outcome summarized the inoculation statistics, attention distribution, involvement correlations, and decision priorities. The experiment result shows the subjects do not receive government¡¦s promotion well. The result also shows the subjects prefer sanitation for prevention. In addition, this study investigates Taiwan¡¦s vaccine and disease prevention development status. The analysis examines Adimmune Corporation and the vaccine market from different aspects. Finally, the conclusion provides recommendations for the people, the vaccine factory, and the government.

ABSTRACT This study aims to investigate the possible relationship between the differences of the male and female brain and vocabulary learning strategies of male and female students. For this purpose, a study has been carried out with a group of 200 students attending the Preparatory Program at TOBB University of Economics and Technology. This study initially aims to identify the differences between the biology of the male and female brain as well as the hormones influencing the memory and vocabulary retention. This information will then be applied to the vocabulary learning strategies of males and females. In order to identify the strategies used by males and females, a questionnaire was administered to a group of students attending the Preparatory Program at TOBB Economy and Technology University. Before the main study, the questionnaire was administered as a pilot study with 50 students from the same achievement group. After the pilot study of the questionnaire / validity, reliability and factor analysis studies were carried out. All of these subjects were at the same level of proficiency. The relationship between the genders and their vocabulary learning strategies was studied according to the results of the study through statistical evaluation through t-test analysis on SPSS. The data collected through the questionnaire were analyzed by comparing them to the literature suggesting the differences between the male and female brain characteristics. As the result of this study, it has been found out that females use more variety of strategies than males. Females have been found to employ determination, social, and cognitive strategies more frequently than males while males employ memory strategies more than females. In addition, there was not a statistically significant difference between the use of metacognitive strategies of male and female participants.

This thesis mainly intends to study and reach some conclusions related to major challenges concerning vocabulary teaching or learning, how vocabulary teaching can be improved, findings obtained from the studies in order to reach that purpose and to what extend the suggested alternative vocabulary techniques are effective. It is also aimed to outline the basic insights of the mind, storage, and retrieval from the literature involving linguistics and language teaching. Based on above mentioned background knowledge, it is also intended to derive some significant conclusions to improve the effectiveness and thus the quality of vocabulary teaching in language instruction. In accordance with the principles of the human memory, how we can alter current vocabulary instruction techniques and activities and what scholars offer language teachers and learners are dealt with in detail. So as to validate and prove the efficiency of suggested techniques and activities, a case study is carried out and findings are discussed at large. Additionally, interviews about vocabulary teaching have been carried out with the involved students and instructors and the obtained data has been evaluated. In the final part of the research, some implications and suggestion related to vocabulary teaching are provided along with the underlying rationale behind them aiming to increase the quality of teaching of lexical items and as a result to increase overall quality of language instruction.
