This dissertation used naturalistically-observed snippets of actual conversations of couples coping with breast cancer to understand how often, with whom, and how couples talk about cancer and other topics, and how these conversations relate to both partners' adjustment to the experience. Fifty-six breast cancer patients undergoing treatment and their spouses wore the Electronically Activated Recorder (EAR) for one weekend and completed adjustment questionnaires at baseline and a two-month follow-up. The first study revealed that couples discussed cancer in fewer than 10% of their conversations, and that these conversations occurred more frequently with each other than with friends and family. Cancer conversations tended to be informational and supportive, and spouses', rather than patients', discussion of cancer tended to be more related to adjustment. The second study analyzed the social language used within couples' cancer-related and other topics of conversation. Specifically, it examined the associations between we-talk (first-person plural pronouns), I-talk (first-person singular pronouns), and you-talk (second-person pronouns) and couples' adjustment. Results revealed that, contrary to prediction, both partners' we-talk was associated with concurrent, rather than future, adjustment. Further, both partners' focus on the spouse, indicated by I-talk and you-talk, was related to better adjustment for spouses. The findings in this dissertation indicate that psychosocial factors influence spouses' adjustment at least as much as patients' adjustment to breast cancer, and that couples without an exclusive focus on the patient may fare better overall.

This article reviews the Electronically Activated Recorder (EAR) as an ambulatory ecological momentary assessment tool for the real-world observation of daily behavior. Technically, the EAR is an audio recorder that intermittently records snippets of ambient sounds while participants go about their lives. Conceptually, it is a naturalistic observation method that yields an acoustic log of a person’s day as it unfolds. The power of the EAR lies in unobtrusively collecting authentic real-life observational data. In preserving a high degree of naturalism at the level of the raw recordings, it resembles ethnographic methods; through its sampling and coding, it enables larger empirical studies. This article provides an overview of the EAR method; reviews its validity, utility, and limitations; and discusses it in the context of current developments in ambulatory assessment, specifically the emerging field of mobile sensing.

This study examined the relationship between emergent imitation skills and social communication skills in 15 to 18 month old infants, using a quantitative correlational research design. Imitation skills are an index of later social cognition and language development, and a critical mechanism in language learning for typically developing children. Social communication skills in this age predict later language skills. The relationship between imitation and social communication is poorly understood in infants. This study looked at the relationship between imitation and social communication at their emergence. This study included 30 typically developing infants, whose participation was volunteered by their parents. They were recruited through posters and word-of-mouth in communities in the Pacific Northwest. Infants’ imitation behaviors were measured using the Motor Imitation Scale (Stone, Ousley, & Littleford, 1997), and their social communication skills were measured using the Communication and Symbolic Behavior Scales- Developmental Profile (Wetherby & Prizant, 2002). This study used a naturalistic observation model so the one-hour play sessions took place in the infants' homes. Sessions were digitally recorded for later scoring and analysis. This study demonstrated a concurrent and predictive relationship between imitation and language understanding in this age group. The study suggests that imitation is an important variable in early language acquisition that needs further study, and needs to be addressed when assessing prelinguistic child development. The study suggests that imitation skills should be fostered early on and provides evidence-based methods for facilitating imitation and language development. / Graduate / 0525 / 0518 / 0620 / 0460 / lhanika@uvic.ca

The prevalence of Alcohol Use Disorders is rapidly increasing among college students. The use of real time monitoring in conjunction with contingency management procedures to reduce alcohol consumption has only recently been developed. Therefore, the purpose of this study was to learn more about natural patterns of alcohol consumption in college-aged adults. A second goal was to evaluate a novel, handheld technology for obtaining reliable samples over extended time periods. College students were given a SoberLinkTM SL2 breathalyzer for eight weeks to monitor their drinking behaviors and asked to self-report the number of drinks consumed each day. Participants received one to three text messages per day to provide breath samples and earned monetary rewards for submitting samples within the allotted time. The results of this study showed that college students tend to consume alcohol during the evening hours and mostly on the weekends. There was a weak to medium correlation between average breath alcohol concentration and conditional average drinks. Compliance with prompts ranged between 77 and 84 percent and monetary earnings ranged between $152 and $160. Naturalistic observations of college drinking may aid in the development of interventions to prevent excessive drinking and the SL2 breathalyzer may have great potential to be used in a number of therapeutic approaches.

Cette étude s’intéresse au rapport des Anciens Égyptiens au sable, élément naturel omniprésent dans le paysage et le quotidien. Le problème est abordé d’un point de vue textuel et plus particulièrement lexicographique. Pour cela, les mentions de six termes appartenant au vocabulaire du sable sont examinées dans des textes mythologiques et rituels, sur une période comprise entre l’Ancien Empire et l’époque romaine. L’enjeu est de déterminer la perception du sable en contexte et de mettre en évidence les croyances élaborées autour de l’élément. Il s’agit de saisir les principes d’introduction du sable au discours religieux afin de mettre en lumière un mécanisme de pensée spécifique à la religion égyptienne : l’observation naturaliste. / This study focuses on the relations between Ancient Egyptians and sand, a natural element, ever-present in landscape and daily life. It is seen from a textual and especially lexicographical point of view. Therefore, quotes of six words related to the vocabulary of sand are studied in mythological and ritual texts from Old Kingdom to Roman Period. The aim is to establish the perception of sand depending on the context and to reveal the beliefs associated to sand. The introduction of sand in the religious speech is taken into account in order to highlight a way of thinking specific to the Egyptian religion : naturalistic observation.

In today's technology based society the rapid proliferation of new machines and systems that would have been undreamed of only a few short years ago has become a way of life. Developments and advances especially in the areas of digital electronics and micro-circuitry have spawned subsequent technology based improvements in transportation, communications, entertainment, automation, the armed forces, and many other areas that would not have been possible otherwise. This rapid "explosion" of new capabilities and ways of performing tasks has been motivated as often as not by the philosophy that if it is possible to make something better or work faster or be more cost effective or operate over greater distances then it must inherently be good for the human operator. Taken further, these improvements typically are envisioned to consequently produce a more efficient operating system where the human operator is an integral component. The formal concept of human-system interface design has only emerged this century as a recognized academic discipline, however, the practice of developing ideas and concepts for systems containing human operators has been in existence since humans started experiencing cognitive thought. An example of a human system interface technology for communication and dissemination of written information that has evolved over centuries of trial and error development, is the book. It is no accident that the form and shape of the book of today is as it is. This is because it is a shape and form readily usable by human physiology whose optimal configuration was determined by centuries of effort and revision. This slow evolution was mirrored by a rate of technical evolution in printing and elsewhere that allowed new advances to be experimented with as part of the overall use requirement and need for the existence of the printed word and some way to contain it. Today, however, technology is advancing at such a rapid rate that evolutionary use requirements have no chance to develop along side the fast pace of technical progress. One result of this recognition is the establishment of disciplines like human factors engineering that have stated purposes and goals of systematic determination of good and bad human system interface designs. However, other results of this phenomenon are systems that get developed and placed into public use simply because new technology allowed them to be made. This development can proceed without a full appreciation of how the system might be used and, perhaps even more significantly, what impact the use of this new system might have on the operator within it. The U.S. Army has a term for this type of activity. It is called "stove-piped development". The implication of this term is that a system gets developed in isolation where the developers are only looking "up" and not "around". They are thus concerned only with how this system may work or be used for its own singular purposes as opposed to how it might be used in the larger community of existing systems and interfaces or, even more importantly, in the larger community of other new systems in concurrent development. Some of the impacts for the Army from this mode of system development are communication systems that work exactly as designed but are unable to interface to other communications systems in other domains for battlefield wide communications capabilities. Having communications systems that cannot communicate with each other is a distinct problem in its own right. However, when developments in one industry produce products that humans use or attempt to use with products from totally separate developments or industries, the Army concept of product development resulting from stove-piped design visions can have significant implication on the operation of each system and the human operator attempting to use it. There are many examples that would illustrate the above concept, however, one that will be explored here is the Army effort to study, understand, and optimize its command and control (C2) operations. This effort is at the heart of a change in the operational paradigm in C2 Tactical Operations Centers (TOCs) that the Army is now undergoing. For the 50 years since World War II the nature, organization, and mode of the operation of command organizations within the Army has remained virtually unchanged. Staffs have been organized on a basic four section structure and TOCs generally only operate in a totally static mode with the amount of time required to move them to keep up with a mobile battlefield going up almost exponentially from lower to higher command levels. However, current initiatives are changing all that and while new vehicles and hardware systems address individual components of the command structures to improve their operations, these initiatives do not necessarily provide the environment in which the human operator component of the overall system can function in a more effective manner. This dissertation examines C2 from a system level viewpoint using a new paradigm for systematically examining the way TOCs operate and then translating those observations into validated computer simulations using a methodological framework. This paradigm is called COmputer Modeling Paradigm And Simulation of Systems (COMPASS). COMPASS provides the ability to model TOC operations in a way that not only includes the individuals, work groups and teams in it, but also all of the other hardware and software systems and subsystems and human-system interfaces that comprise it as well as the facilities and environmental conditions that surround it. Most of the current literature and research in this area focuses on the concept of C2 itself and its follow-on activities of command, control, communications (C3), command, control, communications, and computers (C4), and command, control, communications, computers and intelligence (C4I). This focus tends to address the activities involved with the human processes within the overall system such as individual and team performance and the commander's decision-making process. While the literature acknowledges the existence of the command and control system (C2S), little effort has been expended to quantify and analyze C2Ss from a systemic viewpoint. A C2S is defined as the facilities, equipment, communications, procedures, and personnel necessary to support the commander (i.e., the primary decision maker within the system) for conducting the activities of planning, directing, and controlling the battlefield within the sector of operations applicable to the system. The research in this dissertation is in two phases. The overall project incorporates sequential experimentation procedures that build on successive TOC observation events to generate an evolving data store that supports the two phases of the project. Phase I consists of the observation of heavy maneuver battalion and brigade TOCs during peacetime exercises. The term "heavy maneuver" is used to connotate main battle forces such as armored and mechanized infantry units supported by artillery, air defense, close air, engineer, and other so called combat support elements. This type of unit comprises the main battle forces on the battlefield. It is used to refer to what is called the conventional force structure. These observations are conducted using naturalistic observation techniques of the visible functioning of activities within the TOC and are augmented by automatic data collection of such things as analog and digital message traffic, combat reports generated by the computer simulations supporting the wargame exercise, and video and audio recordings where appropriate and available. Visible activities within the TOC include primarily the human operator functions such as message handling activities, decision-making processes and timing, coordination activities, and span of control over the battlefield. They also include environmental conditions, functional status of computer and communications systems, and levels of message traffic flows. These observations are further augmented by observer estimations of such indicators as perceived level of stress, excitement, and level of attention to the mission of the TOC personnel. In other words, every visible and available component of the C2S within the TOC is recorded for analysis. No a priori attempt is made to evaluate the potential significance of each of the activities as their contribution may be so subtle as to only be ascertainable through statistical analysis. Each of these performance activities becomes an independent variable (IV) within the data that is compared against dependent variables (DV) identified according to the mission functions of the TOC. The DVs for the C2S are performance measures that are critical combat tasks performed by the system. Examples of critical combat tasks are "attacking to seize an objective", "seizure of key terrain", and "river crossings'. A list of expected critical combat tasks has been prepared from the literature and subject matter expert (SME) input. After the exercise is over, the success of these critical tasks attempted by the C2S during the wargame are established through evaluator assessments, if available, and/or TOC staff self analysis and reporting as presented during after action reviews. The second part of Phase I includes datamining procedures, including neural networks, used in a constrained format to analyze the data. The term constrained means that the identification of the outputs/DV is known. The process was to identify those IV that significantly contribute to the constrained DV. A neural network is then constructed where each IV forms an input node and each DV forms an output node. One layer of hidden nodes is used to complete the network. The number of hidden nodes and layers is determined through iterative analysis of the network. The completed network is then trained to replicate the output conditions through iterative epoch executions. The network is then pruned to remove input nodes that do not contribute significantly to the output condition. Once the neural network tree is pruned through iterative executions of the neural network, the resulting branches are used to develop algorithmic descriptors of the system in the form of regression like expressions. For Phase II these algorithmic expressions are incorporated into the CoHOST discrete event computer simulation model of the C2S. The programming environment is the commercial programming language Micro Saintä running on a PC microcomputer. An interrogation approach was developed to query these algorithms within the computer simulation to determine if they allow the simulation to reflect the activities observed in the real TOC to within an acceptable degree of accuracy. The purpose of this dissertation is to introduce the COMPASS concept that is a paradigm for developing techniques and procedures to translate as much of the performance of the entire TOC system as possible to an existing computer simulation that would be suitable for analyses of future system configurations. The approach consists of the following steps: • Naturalistic observation of the real system using ethnographic techniques. • Data analysis using datamining techniques such as neural networks. • Development of mathematical models of TOC performance activities. • Integration of the mathematical into the CoHOST computer simulation. • Interrogation of the computer simulation. • Assessment of the level of accuracy of the computer simulation. • Validation of the process as a viable system simulation approach. / Ph.
