description: ArielRad, the Ariel radiometric model, is a simulator developed to address the challenges in optimising the space mission science payload and to demonstrate its compliance with the performance requirements. Ariel, the Atmospheric Remote-Sensing Infrared Exoplanet Large-survey, has been selected by ESA as the M4 mission in the Cosmic Vision programme and, during its 4 years primary operation, will provide the first unbiased spectroscopic survey of a large and diverse sample of transiting exoplanet atmospheres. To allow for an accurate study of the mission, ArielRad uses a physically motivated noise model to estimate contributions arising from stationary processes, and includes margins for correlated and time-dependent noise sources. We show that the measurement uncertainties are dominated by the photon statistic,and that an observing programme with about 1000 exoplanetary targets can be completed during the primary mission lifetime.

description: Lifestyle media have the power to impact women's understanding of environmentalism and what it means to be a woman environmentalist in the United States.  Surveying popular women's lifestyle media sources in the U.S., I conducted a discourse analysis of various types of environmental narratives, seeking to understand how this media defined environmentalism and the environmentalist, and what the implications of these definitions might be for American culture.  I tracked the intersections of gender, environmentalism, and mass media from an interdisciplinary, feminist perspective, drawing on theorists' conceptions of media framing to draw out recurrent themes.  In surveying a range of lifestyle media sources, I found that media framing of environmental narratives leveraged the American cultural value of individual agency, focusing on the power of private sphere activities to foment change, and using class distinction and educational markers to link environmentalism to sophistication among one's peers.  Media often framed environmental narratives in terms of motherhood archetypes, linking environmentalism to maternalism and implying that mothers bore unique social responsibilities for environmental action.  Finally, environmental narratives in lifestyle media appeared to reflect an underlying effort on the part of media to depoliticize environmentalism, promoting environmentalism as a mainstream value and portraying women environmentalists as the embodiment of traditional American cultural values.  Overall, I found that environmental narratives in lifestyle media framed women's environmental responsibilities in terms of long-standing, static conceptions of womanhood and motherhood, and similarly gendered notions of the social responsibility to care for one's family or community.  Moreover, environmental narratives seemed likely to reinforce hegemonic cultural conceptions of women's identities and social agency.  These narratives therefore have the potential to fuel existing gender inequities tied to social expectations for the division of domestic labor.  Despite these findings, there has been a general dearth of scholarship focused on the implications of such narratives, and the portrayal of women's environmentalism in popular mass media.  The construction of environmentalism in women's lifestyle media will thus benefit from an analysis based in a feminist perspective, providing a basis for future scholarship on the cultural implications of saddling women with the burden of environmental care.

A comparison of two cases in experiential systemic therapy : a case study approach
Creators: name: Prette, Liz
Publisher: name: University of British Columbia
Year: 2009

description: The problem of this study was to examine the variables that contributed to a successful case of Experiential Systemic Couples Therapy as compared to a non-successful case using a qualitative, exploratory case study. The main purposes were: (a) to generate concepts that may have led to or hindered therapeutic change, (b) to investigate the process of change in Experiential Systemic Couples Therapy, and (c) to contribute to the clinical understanding of how change occurs in ExST. The case data sources included documentation (objective measures, situation diaries and reviews of therapy) and video tapes (15 taped sessions from each of the cases). The two cases were chosen using Pinsof's (1988) techniques of Success-Failure Strategy from a larger pool in The Alcohol Recovery Project. A qualitative case study methodology was implemented to discover the major differences between the two cases. Along with these descriptive methods, three sessions from each case were also analyzed using the Vanderbilt Psychotherapeutic Process Scale. The researcher also used Pinsoff's small chunk strategy and analyzed the "best and worst" session of each of the cases. Again a qualitative analysis was done of the sessions, as well as using the Hill (1993) Category Systems. Key findings from each of the cases were identified and compared. The findings revealed nine major differences which occured between the two cases. The analysis of the cases revealed nine major findings associated with outcome. First, three pre-existing variables were discovered to be associated with the successful and unsuccesful case: client variables, stage of change and length of therapy. Second, three findings were delineated as to why change may have occurred: therapeutic alliance, addressing intimacy issues and practicing opportunities in therapy. Finally, three findings were discovered as to how greater change may have occurred: depth of experiencing, therapist techniques and the completion of a 'story' during a therapy session. These findings are integrated with current research. As well, implications for future research and clinical practice are discussed. The limitations of this study and it's methodology are also presented.
On the Unfathomableness of Consciousness by Consciousness: Why do physicists widely agree on the assured extent of their professional knowledge, but not so philosophers? An exchange of letters with Carl Friedrich von Weizsaecker

description: On the occasion of Carl Friedrich von Weizsaecker's 81st birthday, a colloquium was held on July 3, 1993. One of the topics was "The epistemological foundation of physics from Kant to von Weizsaecker". I took part in the discussion. Afterwards I got the impression that I had not succeeded in making my points clear. Therefore, I wrote an explanatory letter to Prof. von Weizsaecker. This was the beginning of a correspondence on the questions intimated by the title above. In addition, a private discussion between Prof. von Weizsaecker and myself took place. Some readers may be interested in the answers which Carl Friedrich von Weizsaecker has given to the naive questions and views of a physicist with only a rudimentary education in philosophy. The starting point of our discussion was my remark that the conspicuous inability of philosophers to agree on the deepest elements of human existence including the basic questions of ethics, which is tantamount to the occurrence of different schools of philosophy competing with each other, could perhaps be traced back to the fundamental inability of man to attain self-knowledge. Physicists, on the other hand, can reach consent, in an equally remarkable way, on the results of their measurements and on whether or not these results agree with the ideas of theory. They just have to deal with res extensa. Here the yardstick does not intend to measure itself, but objects which are external to it, and this is possible. There remains only the question what consequences can be drawn from this realization. Is philosophy, in as much as it gives statements on the totality of human existence, only an expression of the prevailing social circumstances and views, interesting enough as such, but not a gateway to truth?

Subjects: subject: 120199 Architecture not elsewhere classified
subject: FOS: Civil engineering

description: Autonomous construction has been an active research topic for engineers and designers for many years. Meanwhile, technological advancement made in the drone industry is continuously pushing the drone’s capability boundary. The probability of drones actively participating in additive construction is large enough to be realized in the near future. However, there is no system that can control a scalable number of drones for autonomous construction in a dynamic continuous environment. This thesis aims to develop a system for autonomous multi-drone additive construction using deep reinforcement learning-based algorithm. First, the process of multi-drone additive construction is modeled in a computer simulation. Then state-of-art deep reinforcement learning algorithm is applied to achieve collision avoidance in navigation. A software package is then developed and able to be integrated into a 3d modeling software, Rhinoceros, for future use and development for researchers and designers. Finally, this system is applied in two experiments: bricklaying and facade coating to demonstrate usage.

description: Motivation can critically influence learning and memory. Multiple neural mechanisms regulate motivational states, among which signalling via specific neuropeptides, such as NPY in vertebrates and NPF and its short variant sNPF in invertebrates, plays an essential role. The honeybee (Apis mellifera) is a privileged model for the study of appetitive learning and memory. Bees learn and memorize sensory cues associated with nectar reward while foraging and their learning is affected by their feeding state. However, the neural underpinnings of their motivational states remain poorly known. Here we focused on the short neuropeptide F (sNPF) and studied if it modulates the acquisition and formation of colour memories. Artificially increasing sNPF levels in partially fed foragers with a reduced motivation to learn colours resulted in significant colour learning and memory above the levels exhibited by starved foragers. Our results thus identify sNPF as a critical component of motivational processes involved in foraging and in the cognitive processes associated with this activity in honeybees.

Infrasubgeneric designation not validly published:—“ Kalanchoe [subg. Kalanchoe] sect. Stellatopilosae ” (Berger 1930: 404) Maire (1977: 253), nom. inval., (Turland et al. 2018: Art. 41.5).
Thirdly, Maire (1977: 254) treated “ Kalanchoe sect. Crenatae ” Berger (1930: 405) as if validly published by Berger (1930). However, Berger (1930: 404) did not publish “ Kalanchoe [unranked] Crenatae ” at the rank of section. In addition, this designation was not validly published by Berger because it includes K. laciniata (see Maire 1977: 258), the type of the genus Kalanchoe (Turland et al. 2018: Art. 22.1), as was in fact recorded by Maire (1977: 251) himself.
This sectional designation proposed by Maire (1977: 254) should not be cited as “ Kalanchoe sect. Crenatae ” (Berger 1930: 405) Maire (1977: 258), nom. inval., because the proposed basionym, “ Kalanchoe [unranked] Crenatae ” Berger (1930: 405), was, itself, not validly published (Table 9, row IB). A basionym is a legitimate name (Turland et al. 2018: Art. 6.10) that, by definition, was validly published (Turland et al. 2018: 198, Glossary). A name that was not validly published has no status under Turland et al. (2018: Art. 12.1) (see Smith 2020c: 234 for a discussion).

description: We have grown thin films of the Heusler compound Co_2FeSi by RF magnetron sputtering. On (100)-oriented MgO substrates we find fully epitaxial (100)-oriented and L2_1 ordered growth. On Al_2O_3 (11-20) substrates, the film growth is (110)-oriented, and several in-plane epitaxial domains are observed. The temperature dependence of the electrical resistivity shows a power law with an exponent of 7/2 at low temperatures. Investigation of the bulk magnetic properties reveals an extrapolated saturation magnetization of 5.0 mu_B/fu at 0 K. The films on Al_2O_3 show an in-plane uniaxial anisotropy, while the epitaxial films are magnetically isotropic in the plane. Measurements of the X-ray magnetic circular dichroism of the films allowed us to determine element specific magnetic moments. Finally we have measured the spin polarization at the surface region by spin-resolved near-threshold photoemission and found it strongly reduced in contrast to the expected bulk value of 100%. Possible reasons for the reduced magnetization are discussed.

description: Predictions obtained by, e.g., artificial neural networks have a high accuracy but humans often perceive the models as black boxes. Insights about the decision making are mostly opaque for humans. Particularly understanding the decision making in highly sensitive areas such as healthcare or fifinance, is of paramount importance. The decision-making behind the black boxes requires it to be more transparent, accountable, and understandable for humans. This survey paper provides essential definitions, an overview of the different principles and methodologies of explainable Supervised Machine Learning (SML). We conduct a state-of-the-art survey that reviews past and recent explainable SML approaches and classifies them according to the introduced definitions. Finally, we illustrate principles by means of an explanatory case study and discuss important future directions.

description: Anomaly Detection, which deals with the discovery of unusual instances in the data, has always been a challenging area of research and has intrigued many researchers over past few years. As part of our thesis work, we intend to make advances in the area of Spatial Anomaly Detection in highway traffic datasets. We present a framework, which would simplify the process of identifying and geo-locating anomalies and make the results of such anomaly detection easily identifiable and interpretable. We first perform data preprocessing and cleansing for improving data reliability. Second we perform anomaly detection in traffic datasets by adopting sound statistical techniques. Finally, we validate the accuracy of our framework through machine learning algorithms. As part of developing a new framework for facilitating the segregation and easy transformation of anomaly based data results, an intermediate data storage technique is developed. The new framework based interface is devised such that data gets conditionally processed and stored into a markup based format like XML; such that the data can be readily consumable by external APIs for facilitating intuitive spatial and graphical display on the framework's web Interface. We discuss results in real world traffic datasets from the Maryland State Highway Administration.

description: Cognitive assessments are conducted in one of two ways; a trained professional will conduct a face-to-face interview, collecting the answers from the interviewee during the interaction; or a computer will present an inventory as a list of questions and multiple-choice answers. While a trained professional can provide an individualized assessment there is also concern that the interviewee can appear different while interacting with different assessors. Although conducting the assessment using a computer provides a consistent and cost-effective way of conducting an inventory this static process affects interpretation because it does not provide a means of clarification either for the user or the computer: the user to clarify ambiguous wording, or the computer to clarify potential conflicting responses from the user.  This dissertation researches an Intelligent Interviewer conducting a cognitive assessment, specifically a learning style inventory. The Intelligent Interviewer was presented to the participants in two forms: an Embodied Interviewer, where the user and computer conversed vocally and visually; and a Text Interviewer, where the user and computer conversed by typing and reading text. Both the subjective and objective evaluation metrics were studied to determine the user experience, effectiveness, and efficiency of the Intelligent Interviewer.

description: Lower atmospheric global dust storms affect the small- and large-scale weather and variability of the whole Martian atmosphere. Analysis of the CO$_2$ density data from the Neutral Gas and Ion Mass Spectrometer instrument (NGIMS) on board NASA's Mars Atmosphere Volatile EvolutioN (MAVEN) spacecraft show a remarkable increase of GW-induced density fluctuations in the thermosphere during the 2018 major dust storm with distinct latitude and local time variability. The mean thermospheric GW activity increases by a factor of two during the storm event. The magnitude of relative density perturbations is around 20% on average and 40% locally. One and a half months later, the GW activity gradually decreases. Enhanced temperature disturbances in the Martian thermosphere can facilitate atmospheric escape. For the first time, we estimate that, for a 20% and 40% GW-induced disturbances, the net increase of Jeans escape flux of hydrogen is a factor of 1.3 and 2, respectively.

description: A large body of literature exists on evolutionary computing, genetic algorithms, decision trees, codified knowledge, and knowledge management systems; however, the intersection of these computing topics has not been widely researched. Moving through the set of all possible solutions - or traversing the search space - at random exhibits no control over how an organism evolves into a new organism that lies within the search space, also known as the mutation process.  Employing codified human knowledge, the traversal of the search space may be constrained and directed thereby controlling mutation. This reveals the research question: How can codified human knowledge be integrated into the evolutionary mutation process in order to influence the traversal of the search space In order to investigate the research question, a design science approach will begin with a design artifact by creating DEFINE - Dynamic Evolution in Financial Investment Election.   DEFINE employs decision trees as organisms and utilizes ontologies to constrain the mutation process.   This research has the potential to reveal new and unexplored methods of employing human knowledge coupled with evolutionary computing to produce quality knowledge management systems.     Preliminary experiments reveal an advantage, as measured by increased classification accuracy, to incorporating knowledge in the mutation process and also reveal financial markets follow a path of evolution with less than 10 generations to reach optimal fitness.  Additional experiments conclude well-constructed knowledge constrains the mutation process to exercise control over the traversal of the search space whereas poorly-formed or random knowledge has no effect.  Employing knowledge into the mutation process demonstrates making small changes in the organism's structure leads to small changes in the organism's function; however, making large changes showed mixed results.  Performance, as measured by classification accuracy and number of generations to reach an optimum fitness, is improved by making small changes in the organism structure as opposed to random changes.  This research demonstrates the number of years in time series data affects the number of generations required to achieve an optimum fitness.  The methods explored in this research are applied to a financial investing scenario and profitability is shown to lie between two common investment strategies.

description: We analyse observations, spanning 15 years, dedicated to the extreme emission-line object Hen3-209. Our photometric data indicate that the luminosity of the star undergoes marked variations with a peak-to-peak amplitude of 0.65mag. These variations are recurrent, with a period of 16.093+-0.005d. The spectrum of Hen3-209 is peculiar with many different lines (HI, HeI, FeII,...) showing P Cygni profiles. The line profiles are apparently changing in harmony with the photometry. The spectrum also contains [OIII] lines that display a saddle profile topped by three peaks, with a maximum separation of about 600km/s. Hen3-209 is most likely an evolved luminous object suffering from mass ejection events and maybe belonging to a binary system.

description: Preferences and behaviors for privacy management with mobile applications are difficult to capture. Previous measures are mostly based on self-report data, which often does not accurately predict actual user behavior. A deeper understanding was sought, gleaned from observing actual practices. This thesis analyzes 11,777 applications from the Google Play marketplace in order to determine the impact of privacy settings on purchase behavior. This was done by looking at the effect of the number of privacy concessions as well as the effect of individual concessions and category on number of downloads. It was found that users of paid applications do not have a preference for fewer privacy concessions. This study further reinforces the disconnect between the user's often stated preference for privacy and their actual behavior  – a discrepancy known as the “privacy paradox ”. Theoretical and practical implications are discussed.

description: The brain is composed of electrically excitable neuronal networks regulated by the activity of voltage-gated ion channels. Further portraying the molecular composition of the brain, however, will not reveal anything remotely reminiscent of a feeling, a sensation or a conscious experience. In classical physics, addressing the mind-brain problem is a formidable task because no physical mechanism is able to explain how the brain generates the unobservable, inner psychological world of conscious experiences and how in turn those conscious experiences steer the underlying brain processes toward desired behavior. Yet, this setback does not establish that consciousness is non-physical. Modern quantum physics affirms the interplay between two types of physical entities in Hilbert space: unobservable quantum states, which are vectors describing what exists in the physical world, and quantum observables, which are operators describing what can be observed in quantum measurements. Quantum no-go theorems further provide a framework for studying quantum brain dynamics, which has to be governed by a physically admissible Hamiltonian. Comprising consciousness of unobservable quantum information integrated in quantum brain states explains the origin of the inner privacy of conscious experiences and revisits the dynamic timescale of conscious processes to picosecond conformational transitions of neural biomolecules. The observable brain is then an objective construction created from classical bits of information, which are bound by Holevo's theorem, and obtained through the measurement of quantum brain observables. Thus, quantum information theory clarifies the distinction between the unobservable mind and the observable brain, and supports a solid physical foundation for consciousness research.

description: Interruptive notifications in a desktop environment are an important service that knowledge workers rely on for maintaining awareness of information and services outside their current focus. Research to date has focused primarily on empirical laboratory-based testing, which is very specific and out of context of a realistic user environment, and broad ethnographic research, which is not specific enough for meaningful notification system design guidelines. This dissertation aims to address the gap between existing laboratory-based and ethnographic research by conducting a series of studies that explored the notification user experience in a both broad and deep way. The results of this research contribute the following: A catalog of significant contextual factors that affect the notification user experience; a series of models that describe how factors in the notification system context influence the overall user experience; a set of design guidelines, derived from this research but generalized to be applicable to any interruptive notification system.

description: Silica optical microspheres often exhibit ultra-high quality factors, yet, their group velocity dispersion, which is crucial for nonlinear optics applications, can only be coarsely tuned. We experimentally demonstrate that group-velocity dispersion of a silica microsphere can be engineered by coating it with conformal nanometric layers of alumina, yet preserving its ultra-high optical quality factors (\num{\sim e7}) at telecom wavelengths. Using the atomic layer deposition technique for the dielectric coating, which ensures nm-level thickness control, we not only achieve a fine dispersion tailoring but also maintain a low surface roughness and material absorption to ensure a low optical loss. Numerical simulations supporting our experimental results show that the alumina layer thickness is a promising technique for precise tuning of group-velocity dispersion. As an application we demonstrate the generation of Kerr optical frequency combs, showing that the alumina coatings can also sustain the high optical intensities necessary for nonlinear optical phenomena.

In particular, we study an elastic arch subject to an end-shortening that evolves linearly with time, i.e. at a constant rate. For large end-shortening the arch is bistable but, below a critical end-shortening, the arch becomes monostable. We study when and how the arch transitions between states and show that the end-shortening at which the fast 'snap' happens depends on the rate at which the end-shortening is reduced. This lag in snap-through is a consequence of delayed bifurcation and occurs even in the perfectly elastic case when viscous (and viscoelastic) effects are negligible. We present the results of numerical simulations to determine the magnitude of this lag as the loading rate and the importance of external viscous damping vary. We also present an asymptotic analysis of the geometrically-nonlinear problem that reduces the salient dynamics to that of an ordinary differential equation; the form of this reduced equation is generic for snap-through instabilities in which the relevant control parameter is ramped linearly in time. Moreover, this asymptotic reduction allows us to derive analytical results for the observed lag in snap-through that are in good agreement with the numerical results of our simulations. Finally, we discuss scaling laws for the lag that should be expected in other examples of delayed bifurcation in elastic instabilities.

description: The possibility of detecting double flavor violating top quark transitions $t \to u_iτμ$ ($u_i=u,c$) is explored in a model--independent manner, using the effective Lagrangian approach. Low--energy data, on high precision measurements, and current experimental limits are used to constraint the $tu_iH$ and $Hτμ$ vertices and then to calculate the branching ratio BR$(t \to u_iτμ)$. If in the Standard Model BR$(t \to u_iτμ)$ is of the order of $10^{-13}$$-10^{-14}$, higgs--mediated double flavor violating top quark decays can occur with branching ratios ranging from $10^{-3}$ to $10^{-4}$ for 114.4 GeV$/c^2$ $< m_H

description: Blessed by the Internet age, many online retailers (e.g., Amazon.com) have deployed recommender systems to help their customers identify products that may be of their interest in order to improve cross-selling and enhance customer loyalty. Collaborative Filtering (CF) is the most successful technique among different approaches to generating recommendations. Collaborative filtering automates the word-of-mouth process of recommendations by aggregating item ratings of other like-minded users. Although it has achieved huge success in both research and industry, traditional CF suffers a fundamental problem because of its dependence on users' numeric ratings as its sole source of user preference information. However, user ratings are often unable to fully represent user preferences. As a result, it is difficult to identify the true similarity among users based on ratings only. On the other hand, people are more and more comfortable with expressing themselves online using free-form text (e.g., blogs). As a result, user text reviews on different products have become a common source for consumers to share and receive information about products. Recent studies have also found that user reviews have significant impact on online businesses' sales. Inspired by the results of these studies, I propose an integrated approach to collaborative filtering called urCF (User Review enhanced Collaborative Filtering) that integrates user text reviews into memory-based collaborative filtering in order to better model users' preferences and in turn enhance the performance of CF-based recommender systems. This research uses existing text mining techniques to extract user opinions on item features. It proposes a new weighting scheme based on TF-IDF to measure the priority of item features in influencing users' overall opinions of different items. This study also explores and compares several different approaches to integrating user opinion information extracted from user text reviews into the user similarity measurement of traditional CF-based recommender systems. The proposed urCF system is evaluated against existing approaches using a dataset collected from Yahoo! Movies. The results show that the proposed urCF system significantly improved the performance of memory-based recommender systems.

description: A simple physical model for long-duration gamma ray bursts (GRBs) is used to fit the redshift (z) and the jet opening-angle distributions measured with earlier GRB missions and with Swift. The effect of different sensitivities for GRB triggering is sufficient to explain the difference in the z distributions of the pre-Swift and Swift samples, with mean redshifts of ~1.5 and ~2.7, respectively. Assuming that the emission properties of GRBs do not change with time, we find that the data can only be fitted if the comoving rate-density of GRB sources exhibits positive evolution to z >~ 3-5. The mean intrinsic beaming factor of GRBs is found to range from ~34-42, with the Swift average opening half-angle ~10 degree, compared to the pre-Swift average of ~7 degree. Within the uniform jet model, the GRB luminosity function is proportional to L^{-3.25}_*, as inferred from our best fit to the opening angle distribution. Because of the unlikely detection of several GRBs with z = 5 and z >= 7, respectively, assuming continued positive evolution of the GRB rate density to high redshifts.

description: Feminism within the British Owenite movement was complex in its language and meaning and difficult to define.  Using publications by Robert Owen, writings by other Owenites and Owenite newspapers, the Pioneer, and the New Moral World, this paper is an attempt to analyze feminism within the Owenite movement.  Historians such as Barbara Taylor and Anna Clark suggest that feminism was wholly rejected by the British working class in the later 1830s and 1840s because of Owenism's marriage with the working class.  Instead of such a rise-and-fall narrative, the evidence in Owenite periodicals suggests that feminism was always a marginal strain within Owenite attitudes to women's issues, and mixed with far more traditional gender views even among the more progressive thinkers on the subject.
Non-existence of Irreversible Processes in Compact Space Time

description: It is shown that if physical space time were truly compact there would only be of the order of one solutions to the classical field equations with a weighting to be explained. But that would not allow any peculiar choice of initial conditions that could support a non-trivial second law of thermodynamics. We present a no-go theorem: Irreversible processes would be extremely unlikely to occur, for the almost unique solution for the intrinsically compact space time world, although irreversible processes are well known to occur in general.What we here assume -- compact space time -- excludes that universe could exist eternally.

A narrative analysis of the stories of children who witness domestic abuse
Creators: name: Douglas, Stephen

description: It is estimated that over 500,000 Canadian homes live with family violence (B.C./Yukon Society of Transition Houses, 1995). Research in the past decade has examined the relationship between spousal abuse and childhood adjustment assessed through behavior. The cognitive-emotional processes through which a child attempts to adjust to a domestic atmosphere of violence, however, remain largely unexplored. This study therefore sought to gain insight into the internal working models of children who witness domestic violence. Twenty-five children between the ages of 7 and 12 were interviewed using the projective technique of storytelling, prior to participating in the Children Who Witness Abuse Program operated by three Lower Mainland Vancouver agencies. Their temperament was rated along the dimensions of Emotionality, Activity, and Sociability by the group counsellors at the end of the ten-week program using the Colorado Childhood Temperament Inventory (Buss & Plomin, 1984). Subjective observations of behavioral styles within the group were also'noted. This was an exploratory study. In the analysis, life scripts were identified from the stories narrated by these children. Individually, each child's cognitive interpretations, affective experience, and developmental needs were examined to suggest an appropriate therapeutic response. Three clusters of life scripts were identified. One cluster includes children with the life script, "You can/must figure it out/solve the problem/ fix it." The second cluster expresses, "I must get what I want." The third cluster shares a common perception, "The world is a dangerous place, so..." The conclusion to this script varies, according to which the study has identified five subgroups; "...get help," "...you will feel sad," "...get away and hide," "...you'll get hurt," and "...don't worry, it will get better and you will feel happy then." These clusters aid counsellors and group facilitators in recognizing children's adjustment processes and needs. In the discussion, the intermediary role of temperament was examined. Results were evaluated according to the Cycle-of-Violence Hypothesis, family systems, attachment theory, and literature on Post-Traumatic Stress Disorder. Finally, the role of variables cited in previous studies was considered, including gender, time since separation, shelter versus non-shelter populations, position within their family constellation, ongoing contact with the abusive parent, parents' abuse of drugs or alcohol, and physical, sexual, or emotional abuse experienced directly by the children. The merits of the storytelling interview as an intake instrument have been demonstrated. This study has generated tentative hypotheses to be tested for validity through future research. This may contribute to our understanding of the affective and cognitive interpretations of children who witness domestic abuse that, in turn, can enhance their therapists' interventions.
