Abstract (sommario):

The calculation of the unfoldings surfaces has many practical applications, especially in the connection pipes of equal or different sizes. The work has the role of establishing a pipeline of an industrial installation, with a known configuration, composed by cylindrical, conical and prismatic surfaces. This paper, based on methods of descriptive geometry, gives all the necessary information to obtain the unfoldings and after that, by using numerical analysis, there are presented some algorithms used in developing the piece.

Testo completo

Abstract (sommario):

Using mathematical models with the purpose to understand and store knowlegde about a system is not a new field in science with early contributions dated back to, e.g., Kepler’s laws of planetary motion.

The aim is to obtain such a comprehensive predictive and quantitative knowledge about a phenomenon so that mathematical expressions or models can be used to forecast every relevant detail about that phenomenon. Such models can be used for reducing pollutions from car engines; prevent aviation incidents; or developing new therapeutic drugs. Models used to forecast, or predict, the behavior of a system are refered to predictive models. For such, the estimation problem aims to find one model and is well known and can be handeled by using standard methods for global nonlinear optimization.

Descriptive models are used to obtain and store quantitative knowledge of system. Estimation of descriptive models has not been much described by the literature so far; instead the methods used for predictive models have beed applied. Rather than finding one particular model, the parameter estimation for descriptive models aims to find every model that contains descriptive information about the system. Thus, the parameter estimation problem for descriptive models can not be stated as a standard optimization problem.

The main objective for this thesis is to propose methods for estimation of descriptive models. This is made by using methods for nonlinear optimization including both new and existing theory.

Testo completo

Abstract (sommario):

Injury now surpasses disease as the leading global cause of premature death and disability, claiming over 5.8 millions lives each year. However, unlike disease, which has been subjected to a rigorous epidemiologic approach, the field of injury prevention and control has been a relative newcomer to scientific investigation. With the distribution of injury now well described (i.e. ???who???, ???what???, ???where??? and ???when???), the underlying hypothesis is that progress in understanding ???how??? and ???why??? lies in classifying injury occurrences aetiologically. The advancement of a means of classifying injury aetiology has so far been inhibited by two related limitations: 1. Structural limitation: The absence of a cohesive and validated aetiological taxonomy for injury, and; 2. Methodological limitation: The need to manually classify large numbers of injury cases to determine aetiological patterns. This work is directed at overcoming these impediments to injury research. An aetiological taxonomy for injury was developed consistent with epidemiologic principles, along with clear conventions and a defined three-tier hierarchical structure. Validation testing revealed that the taxonomy could be applied with a high degree of accuracy (coder/gold standard agreement was 92.5-95.0%), and with high inter- and intra- coder reliability (93.0-96.3% and 93.5-96.3%). Practical application demonstrated the emergence of strong aetiological patterns which provided insight into causative sequences leading to injury, and led to the identification of effective control measures to reduce injury frequency and severity. However, limitations related to the inefficient and error-prone manual classification process (i.e. average 4.75 minute/case processing time and 5.0-7.5% error rate), revealed the need for an automated approach. To overcome these limitations, a knowledge acquisition (KA) software tool was developed, tested and applied, based on an expertsystems technique known as ripple down rules (RDR). It was found that the KA system was able acquire tacit knowledge from a human expert and apply learned rules to efficiently and accurately classify large numbers of injury cases. Ultimately, coding error rates dropped to 3.1%, which, along with an average 2.50 minute processing time, compared favourably with results from manual classification. As such, the developed taxonomy and KA tool offer significant advantages to injury researchers who have a need to deduce useful patterns from injury data and test hypotheses regarding causation and prevention.

Abstract (sommario):

This mixed methods research study describes the implementation of Applied Science and Technology (AST) - a recently-implemented Secondary 3 and 4 program in Quebec. AST is part of the Math, Science and Technology Domain of the Quebec Education Program (QEP), a comprehensive reform of the K-11 Quebec curriculum. It is very different from the science programs of the past. AST teaches science by emphasizing the applications of science and technology in the real world of the students. The program uses the pedagogy of constructivism and integrates engineering technology into the science content.This study examines the extent to which teachers follow the AST curriculum and use a constructivist/inquiry-based pedagogy. It also described the students' engagement with the program and their motivation and interest in learning science. Quantitative data were collected from online surveys of AST teachers and students as well as school board enrolment figures. Qualitative data came from extensive visits to AST classrooms in action and interviews with teachers, principals and science consultants. The data were triangulated to arrive at a comprehensive description of the implementation of AST. The study examines the teachers' epistemology with relation to the AST curriculum. It found that many teachers, with support from consultants and new science teaching resources, are successfully incorporating applications of science and engineering technology as prescribed by AST. They are using some constructivist pedagogical practices – accessing prior knowledge, providing an active learning environment and contextualizing the content within the students' reality. Some teachers, on the other hand, are finding it quite challenging to fully incorporate the technology aspect of the curriculum and the constructivist nature of the pedagogy. Students show strong motivation to learn science and express satisfaction with their experiences in AST when the AST activities are hands-on, have personal meaning and give them a measure of autonomy and challenge.
Cette étude de méthodes mixtes décrit la mise en œuvre du programme d'applications technologiques et scientifiques (ATS) qui a été récemment mis en œuvre au Québec en Secondaire 3 et 4. ATS fait partie du domaine de la mathématique, de la science et de la technologie du Programme de formation de l'école québécoise, une réforme globale au Québec. Il est très différent des programmes scientifiques du passé. ATS enseigne la science en mettant l'accent sur les applications de la science et de la technologie dans le monde réel des élèves. Le programme utilise la pédagogie du constructivisme et intègre la technologie d'ingénierie dans le contenu scientifique. L'étude a examiné l'épistémologie des enseignants par rapport au programme ATS. Elle a aussi examiné la mesure dans laquelle les enseignants et enseignantes suivaient le programme de l'ATS et utilisaient la pédagogie du constructivisme. Il a également décrit l'engagement des étudiants avec le programme et leur motivation et leur intérêt pour l'apprentissage des sciences. Les données quantitatives ont été recueillies à partir des sondages en ligne des enseignants et des étudiants de l'ATS ainsi que des chiffres d'inscription des commissions scolaires. Les données qualitatives proviennent de plusieurs visites dans les classes d'ATS en action et des entrevues avec des enseignants et enseignantes, des directeurs et directrices d'école et des conseillers et conseillères pédagogiques. Les données ont été triangulées pour arriver à une description exhaustive de la mise en œuvre de l'ATS. L'étude a révélé que les enseignants, avec l'appui des conseillers pédagogiques et de nouvelles ressources d'enseignement des sciences, incorporent avec succès les applications de la technologie et de l'ingénierie tel que prescrit par l'ATS. Ils utilisent certaines pratiques pédagogiques constructivistes - accéder à la connaissance préalable, fournir un environnement d'apprentissage actif et mettre en contexte le contenu dans la réalité des élèves. Certains enseignants et enseignantes, d'autre part, trouvent qu'il est très difficile d'intégrer pleinement l'aspect technologique du programme et la nature constructiviste de la pédagogie. Les élèves montrent une forte motivation pour apprendre la science et se disent satisfaits de leur expérience dans l'ATS lorsque les activités sont pratiques, ont une signification personnelle et leur donnent un certain niveau d'autonomie et défi.

Abstract (sommario):

Keystone Science School (KSS) is a residential outdoor education facility set high in the Rocky Mountains of Colorado. Initially as a classroom teacher in a nearby town, I observed first-hand the positive impact of experiences had by my students at KSS on their attitudes toward learning science. This research was designed as a descriptive study to analyze how KSS uses outdoor methods and strategies to positively effect student attitudes toward learning science. Over the course of several weeks, participating students and teachers were surveyed about their experiences (typically 3-day/2-night) at Keystone Science School. Instructors and field groups were also observed on several occasions to analyze the degree to which particular methods and strategies were being employed, and their effectiveness on student interest and engagement in science. The results suggest that with an overwhelming positive view from students and teachers about the effectiveness of their outdoor learning experiences, student age, student gender, and instructor gender had some effect on these attitudes. Boys tended to be slightly more comfortable learning outdoors than girls, and younger students (ages 9-11) generally more comfortable than older students (ages 12-14) especially among girls. Students also reported being slightly more comfortable learning outdoors with male instructors, and tended to rate the abilities of male instructors slightly higher. The findings of this result support the conclusion that methods and strategies used in outdoor education are more effective at developing positive attitudes toward learning science than typical classroom experiences.

Abstract (sommario):

This study presents the specific problem surrounding the lack of empirical research for improving engagement and ongoing supervision between criminal justice practitioners and offenders. The purpose of this qualitative descriptive single-case study dissertation aimed to investigate job roles and social contact for improvement of engagement with special needs federal offenders in community corrections. This study used a descriptive framework comprised of, education, training, and leadership and management as a special interest. Face-to-face semi-structured interviews used a purposeful and snowball approach. The participants were 10 criminal justice practitioners, five Case Managers and five United States Probation Officers that provide transitional services to the federal offenders with special needs. Three themes emerged based on the participant’s perceptions and experiences regarding job roles and social contacts with offenders. The themes were as follows: (a) managing offenders and professionalism, (b) influence of education and training, and (c) setting the tone and culture of the organization. The research discovered that a professional rapport is essential for engaging offenders. This study discovered the ramifications of communicating expectations of transitioning into society and its impact on recidivism. Further implications for leadership to consider based on this study is a need for a comprehensive approach for how to properly mange offenders with special needs. Recommendations for seeking appropriate means for offering professional development opportunities for all practitioners in community corrections is proposed to correctional leaders.

Testo completo

Abstract (sommario):

This descriptive, non-experimental, quantitative study was designed to answer the broad question, “What do grades mean?” Core academic subject middle school teachers from one large, suburban school district in Virginia were administered an electronic survey that asked them to report on aspects of their grading practices and assessment methods for one class taught during the 2008-2009 school year. The survey addressed the following topics: 1) primary purposes for grades, 2) attitudes toward grading, 3) assessment method, and 4) grading practices. Additionally, the study examined the relationship between teachers’ reported assessment and grading methods and student achievement. Overall results and results disaggregated by subject area, grade level, and student ability level suggest that teachers are consistent in what they consider the primary purposes for grades. The vast majority indicated that grades should communicate student levels of mastery of content and skills. However, sizable percentages of teachers reported that they also considered non-academic indicators such as effort, attendance, and paying attention in class when determining student grades, suggesting a lack of alignment between their reported beliefs and practice. The study examined the extent to which teachers’ reported grading and assessment practices were consistent with those recommended in the literature on measurement and assessment. The study findings are consistent with those of findings from previous studies suggesting that teachers engage in “hodgepodge grading,” a practice which incorporates non-academic factors into student grades. The results also show that teachers use a variety of assessment methods and types of questions when measuring student achievement. The results indicate that projects, student exhibits, essays, inclusion of zeros, and extra credit were associated with higher levels of student achievement. Conversely, norm-referencing, classwork, participation, and matching were negatively correlated with student grades and test scores.

Devuyst, Danielle. "Application of Spatial and Descriptive Analysis Methods to Determine Relationship Between Hardware Subsidies and the Sanitation Marketplace". Scholar Commons, 2016. http://scholarcommons.usf.edu/etd/6081.

Testo completo

Abstract (sommario):

Sanitation marketing is an emerging approach of strengthening the local private sector to implement scalable and sustainable improved sanitation coverage in developing countries, specifically among the poor. It encourages the enhancement of sanitation market supply and demand by developing distribution infrastructure and stimulating consumer interest. Unlike interventions that provide hardware subsidies to initiate sanitation demand, financial support for sanitation marketing is used exclusively for the research and development of the market; this encourages the private sector to become independent and self-sufficient. Qualitative data suggests that while sanitation marketing projects have been successful at implementing replicable and sustainable sanitation coverage, they are not effective in close proximity to other programs that provide hardware subsidies. The aim of this study is to determine how hardware subsidies impacted iDE’s (formerly International Development Enterprise) Cambodia Sanitation Marketing Scale-Up (SMSU) project using quantitative data collected between 2010 and 2014, and to develop an approach that best illustrates this relationship. Using their project database of 48,844 transactions in 9 provinces, QGIS 2.8.1 and MS Excel were used to determine the correlations between the NGO (subsidized) and customer sales. QGIS maps and time-lapse animations were effective in spatially juxtaposing the quantity and location of both NGO and customer sales, and MS Excel charts quantified the relationship as a function of time, identifying opposing correlational patterns. Within the Cambodia SMSU project, the provision of hardware subsidies (represented by NGO sales) resulted in the attrition of the sanitation marketplace (represented by customer sales) when the NGO sales landed between 71 and 889 in a single month, averaging 400 NGO sales in a month. Overall, 14 districts showed decreased customer sales in the presence of subsidies, and 36 districts showed increased customer sales in the presence of subsidies. Within this study, any district with over 395 sales in one month showed a decline in customer sales. There were 106 months within this project that the NGO and customer sales had a positive correlation and 110 months showing a negative correlation.

Abstract (sommario):

L’épidémiologie de terrain peut être définie comme un ensemble de méthodes de collecte et de traitement de l’information combinant successivement les approches de l’épidémiologie descriptive mais aussi celles de l’épidémiologie analytique. La finalité de l’analyse descriptive sera de décrire et de quantifier la survenue du phénomène étudié dans une population donnée, permettant ainsi la formulation d’hypothèses préalables à la phase analytique. Phase, qui se focalisera sur les "associations" entre des "facteurs de risque" et la survenue du phénomène étudié. Dans la réponse aux questionnements posés ces deux phases les méthodes statistiques seront des outils incontournables. Afin que les résultats produits par ces analyses soient non seulement utiles mais aussi valables et utilisables, une bonne identification et une application adéquate des méthodes d’analyse s’avèreront primordiales.

A côté de ce constat méthodologique, il y a, dans le champ des traumatismes, tant en Belgique, qu’en pays en développement, la quasi absence d’informations pertinentes et rigoureuses pour documenter l’importance de cette problématique dans le champ de la santé. Pourtant, selon l’Organisation Mondiale de la Santé, plus de 5 millions de personnes décèdent des suites d’un traumatisme chaque année, avec 90% de ces décès survenant dans les pays à faible revenu ou à revenu intermédiaire. En Europe, les données montrent qu’une personne décède toutes les deux minutes des suites d’un traumatisme, et que pour chaque citoyen européen qui en meure, 25 personnes sont admises à l’hôpital, 145 sont traitées en ambulatoire et plus encore se font soigner ailleurs.

Au vu du double constat, qui est, d’une part, que les méthodes statistiques ne sont pas toujours exploitées correctement, et d’autre part, qu’il y a un manque d’informations appropriées et rigoureuses pour documenter l’ampleur du problème des traumatismes; ce travail de thèse poursuit l’objectif majeur, de montrer l’intérêt qu’il y a à appliquer de manière pertinente, adéquate et complète, des méthodes statistiques (univariées, multivariables et multivariées) adaptées aux différentes sources de données disponibles, afin de documenter l’importance des traumatismes, et des facteurs qui y sont associés, tant en pays industrialisés (exemple de la Belgique) qu’en pays en développement (exemple du Cameroun).

La partie classiquement appelée "résultats", correspond dans ce travail à deux chapitres distincts. Le premier fait la synthèse de ce qui a été objectivé par la revue de la littérature en termes de sources de données exploitées et de méthodes d’analyse statistique utilisées. Le second correspond à l’exploitation de quatre bases de données :une "généraliste et populationnelle" (First Health of Young People Survey - Cameroun), une "généraliste et hospitalière" (Résumé Hospitalier Minimum - Belgique), une "spécifique et populationnelle" (données issue de compagnies d’assurances belges), et une " spécifique et hospitalière" (Service SOS Enfants du CHU St Pierre - Belgique).

Les constats majeurs à l’issue de ce travail sont qu’il est possible de trouver dans le panel des méthodes statistiques "classiques", les méthodes nécessaires pour répondre aux questionnements de surveillance "en routine" en termes d’occurrence et de facteurs associés. L’accent devrait être mis sur une (meilleure) utilisation (justifiée, correcte et complète) de ces méthodes et sur une meilleure présentation (plus complète) des résultats. L’utilisation adéquate s’assurant d’une part, par une meilleure formation en méthodologie statistique pour les praticiens mais aussi par l’intégration, à part entière, des statisticiens dans les équipes de recherches. En ce qui concerne les sources de données utilisées, le potentiel d’information existe. Chaque source de données a ses avantages et ses inconvénients mais utilisées conjointement elles permettent d’avoir une vision plus globale du fardeau des traumatismes. L’accent devrait être mis sur l’amélioration de la disponibilité, la mise en commun mais aussi sur la qualité des données qui seraient disponibles. Dès lors, en vue de s’intégrer dans une dynamique de "Système de Surveillance des Traumatismes", une réflexion sur une utilisation globale (qu’elle soit couplée ou non) de ces différentes sources de données devrait être menée.

En Belgique, de nombreuses données, contenant de l’information sur les traumatismes, sont collectées en routine, au travers des données hospitalières, et ponctuellement, au travers de données d’enquêtes. Actuellement, ces données, dont la qualité reste discutable pour certaines, sont sous-utilisées dans le champ qui nous intéresse. Dans le futur, "plutôt que de ne rien savoir", il est important de continuer à exploiter l’existant pour produire et diffuser de l’information, mais cette exploitation et cette diffusion doivent s’accompagner non seulement de réflexion mais aussi d’action sur la qualité des données. En ce qui concerne l’utilisation des méthodes statistiques, nous préconisons une double approche :l’intégration et la formation. Par intégration, nous entendons le fait qu’il faut d’une part considérer le statisticien comme un professionnel ayant à la fois des compétences techniques pointues sur les méthodes, qui pourront être mises à disposition pour garantir le bon déroulement de la collecte et de l’analyse des données, mais aussi comme un chercheur capable de s’intéresser plus spécifiquement à des problématiques de santé publique, comme la problématique des traumatismes par exemple. Par formation, nous entendons le fait qu’il est essentiel d’augmenter et/ou de parfaire non seulement les connaissances des futurs professionnels de la santé (publique) en cours de formation mais aussi celles des praticiens déjà actifs sur le terrain et dès lors premiers acteurs de la collecte de l’information et de son utilisation dans une démarche de prise de décision, de détermination de priorité d’action et d’évaluation.

L’objectif majeur de ce travail de thèse était de montrer l’intérêt qu’il y a à appliquer de manière pertinente, adéquate et complète, des méthodes statistiques adaptées aux différentes sources de données disponibles, afin de documenter l’importance des traumatismes, et des facteurs qui y sont associés. En ayant discuté de l’existence de plusieurs sources potentielles de données en Belgique et en ayant appliqué une série de méthodes statistiques univariées, multivariables et multivariées, sur quelques-unes de celles-ci, nous avons montré qu’il était possible de documenter le fardeau des traumatismes au-travers de résultats utiles mais aussi valables et utilisables dans une approche de santé publique.

Abstract (sommario):

Improvisational Leadership: A Descriptive Case Study of the Complex Problem-Solving Experiences of a High-Functioning Federal Government Interdisciplinary Team This study described the symbiotic relationship between shared leadership, organizational improvisation, and symbolic interactionism in generating improvisational leadership vis a vis the complex problem-solving experiences of a high-functioning federal government interdisciplinary team of six veterinarians. The study had a dual goal orientation: (a) to describe members' experiences of complex problem-solving; and (b) to describe how members shared leadership during these experiences. The grand tour question for this study was: What is the nature of improvisational leadership via the complex problem-solving experiences of a high-functioning federal government interdisciplinary team?

The purpose of this study was to describe the nature of improvisational leadership in the complex problem-solving experiences of a high-functioning federal government interdisciplinary team. This study observed that by virtue of their interdisciplinary-interdependent expertise, members were perpetually engaged in interactive knowledge exchange. The research revealed that the medium for these exchanges was polylogue or concurrent, multidirectional, ongoing conversations among the members. The study determined that through this level of discourse and interactivity in real-time, the foci remained on the situation specific needs and in turn placed the needed expertise in the leadership position/role.

The study was designed to broaden understanding concerning the nature of improvisational leadership via the complex problem-solving experiences of a high-functioning federal government interdisciplinary team through describing leadership as an emergent consequence of the needs of the moment, the actions and interactions among members, and the available material, cognitive, affective, and social resources brought to bear in process.

Abstract (sommario):

This paper presents one element of a larger project that probes for systematicand predictable patterns of variability/volatility in baseball's descriptivestatistics. The larger project standardizes many baseball indices along anevent metric and provides relative estimates of each index’s point of inflectiontoward an empirical asymptote. Specifically these estimates reflect deviationsin sensitivity to “sample size” (e.g., which descriptive statistics are more orless robust across events). The end purpose of this broader investigation is aqualifier to be associated with such statistics: sample size sensitivity (TripleS). Not because it's needed, but because, colloquially, discussions of baseballstatistics are commonly qualified by the cautionary statement, "well, it's asmall sample size". The current presentation highlights the process and resultsof estimating the logarithmic event function of one statistic, batting average,and we will provide real-time projections of accuracy (our estimated functionversus in-coming baseball data that occurs during the CARMA conference).Results have implications for the integration of BigData applications intodigestable summary statistics that appeal to a broad-reaching audience withpractical implications and meaning.

Abstract (sommario):

The problem this paper addresses is the tension between descriptive and normative approaches to design theory and methodology. Descriptive approaches typically seek to document, formalize and/or automate existing ad hoc design methods, towards the goal of making current best practices available to all. In contrast, normative approaches attempt to improve upon existing design practices, towards a new method for how design should be done. Both approaches have strengths and weaknesses. This paper seeks to resolve some of the tension between the two approaches. It presents a new method for designing a design system that synergistically exploits the strengths while remedying the weaknesses of both normative and descriptive methods. An illustration that employs immersive computing technology (ICT) to remedy some of the cognitive biases that might occur in a normative mathematical model for disassembly planning is presented.

Abstract (sommario):

Abstract This paper presents the innovative approaches that can be implemented in teaching descriptive geometry by using a Computer-Aided-Design-Drafting (CADD) software. Examples of line relations, line/surface relations, and plane/cylindrical solid intersections are given in the paper. The paper first discusses the principles of descriptive geometry, and then focuses on how these principles can be applied in a CADD environment. In addition, new methods that take advantage of CADD are also provided. The paper emphasizes creativity while solving descriptive problems by using a CADD software. Although all examples illustrated in CADKEY, the concepts revealed in this paper can be applied to other 3-D CADD software, such as AutoCAD 10 and will significantly improve the engineering student’s CADD skills.

Abstract (sommario):

In many settings just finding a good clustering is insufficient and an explanation of the clustering is required. If the features used to perform the clustering are interpretable then methods such as conceptual clustering can be used. However, in many applications this is not the case particularly for image, graph and other complex data. Here we explore the setting where a set of interpretable discrete tags for each instance is available. We formulate the descriptive clustering problem as a bi-objective optimization to simultaneously find compact clusters using the features and to describe them using the tags. We present our formulation in a declarative platform and show it can be integrated into a standard iterative algorithm to find all Pareto optimal solutions to the two objectives. Preliminary results demonstrate the utility of our approach on real data sets for images and electronic health care records and that it outperforms single objective and multi-view clustering baselines.

Abstract (sommario):

In this paper, I offer a perspective into a creative research practice I have come to term as Ecological Performativity. This practice has evolved from a number of non-linear audiovisual installations that are intrinsically linked to geographical and everyday phenomena. The project is situated in ecological discourse that seeks to explore conditions and methods of co-creative processes derived from an intensive data-gathering procedure and immersion within the respective environments. Through research the techniques explored include computer vision, data sonification, live convolution and improvisation as a means to engage the agency of material and thus construct non-linear audiovisual installations. To contextualize this research, I have recently reoriented my practice within recent critical, theoretical, and philosophical discourses emerging in the humanities, sciences and social sciences generally referred to as ‘the nonhuman turn’. These trends currently provide a reassessment of the assumptions that have defined our understanding of the geo-conjunctures that make up life on earth and, as such, challenge the long-standing narrative of human exceptionalism. It is out of this reorientation that the practice of Ecological Performativity has evolved.

Abstract (sommario):

The article clarifies of gender identity stereotypes in modern media. The main gender stereotypes covered in modern mass media are analyzed and refuted. The model of gender relations in the media is reflected mainly in the stereotypical images of men and woman. The features of the use of gender concepts in modern periodicals for women and men were determined. The most frequently used derivatives of these macroconcepts were identified and analyzed in detail. It has been found that publications for women and men are full of various gender concepts that are used in different contexts. Ingeneral, theanalysisofthe concept-maximums and concept-minimum gender and their characteristics is carried out in the context of gender stereotypes that have been forme dand function in the society, system atizing the a ctual presentations. The study of the gender concept is relevant because it reveals new trends and features of modern gender images. Taking into account the special features of gender-labeled periodicals in general and the practical absence of comprehensive scientific studies of the gender concept in particular, there is a need to supplement Ukrainian science with this topic. Gender psychology, which is served by methods of various sciences, primarily sociological, pedagogical, linguistic, psychological, socio-psychological. Let us pay attention to linguistic and psycholinguistic methods in gender studies. Linguistic methods complement intelligence research tasks, associated with speech, word and text. Psycholinguistic methods used in gender psychology (semantic differential, semantic integral, semantic analysis of words and texts), aimed at studying speech messages, specific mechanisms of origin and perception, functions of speech activity in society, studying the relationship between speech messages and gender properties participants in the communication, to analyze the linguistic development in connection with the general development of the individual. Nowhere in gender practice there is the whole arsenal of psychological methods that allow you to explore psychological peculiarities of a person like observation, experiments, questionnaires, interviews, testing, modeling, etc. The methods of psychological self-diagnostics include: the gender aspect of the own socio-psychological portrait, a gender biography as a variant of the biographical method, aimed at the reconstruction of individual social experience. In the process of writing a gender autobiography, a person can understand the characteristics of his gender identity, as well as ways and means of their formation. Socio-psychological methods of studying gender include the study of socially constructed women’s and men’s roles, relationships and identities, sexual characteristics, psychological characteristics, etc. The use of gender indicators and gender approaches as a means of socio-psychological and sociological analysis broadens the subject boundaries of these disciplines and makes them the subject of study within these disciplines. And also, in the article a combination of concrete-historical, structural-typological, system-functional methods is implemented. Descriptive and comparative methods, method of typology, modeling are used. Also used is a method of content analysis for the study of gender content of modern gender-stamped journals. It was he who allowed quantitatively to identify and explore the features of the gender concept in the pages of periodicals for women and men. A combination of historical, structural-typological, system-functional methods is also implemented in the article. Descriptive and comparative methods, method of typology, modeling are used. A method of content analysis for the study of gender content of modern gender-labeled journals is also used. It allowed to identify and explore the features of the gender concept quantitatively in the periodicals for women and men. The conceptual perception and interpretation of the gender concept «woman», which is highlighted in the modern gender-labeled press in Ukraine, requires the elaboration of the polyfunctionality of gender interpretations, the comprehension of the metaphorical perception of this image and its role and purpose in society. A gendered approach to researching the gender content of contemporary periodicals for women and men. Conceptual analysis of contemporary gender-stamped publications within the gender conceptual sphere allows to identify and correlate the meta-gender and gender concepts that appear in society.

Abstract (sommario):

Research methodology. The following methods were used in this research: general scientific methods (descriptive, analysis, synthesis, comparison) and special (structural, hermeneutic, narrative, method of content analysis). We identified words related to the concept of the enemy and determined the context in which they are used by the authors of the collections Results. The formats of reflection of military reality in collections of military documentaries are investigated. It is emphasized that the authors-observers of events as professional communicators form a vision of events based on categories understandable to the audience – «own» and «others». Instead, the authors-participants go events have more creative space and pay more attention to their own emotional state and reflections. It is defined how the enemy is depicted and what place he occupies in the military reality represented by the authors. It is emphasized that the authors reflect the enemy in different ways. In particular, the authors-observers of the events tried to form a comprehensive vision of the events, and therefore paid much attention to the opposite side of the military conflict. Authors-participants of the events tend to show the enemy as a mass to be opposed. In such collections, the enemy is specified only in the presence of evidence confirming the presence of Russians or militants. Novelty. The research for the first time investigates the methods of representation of military activity in the collections of Ukrainian military documentaries. The article is devoted to the analysis of how the authors represent the enemy. Practical importance. The analysis of collections of military documentaries will allow to study the phenomenon of war and to trace the peculiarities of the authors’ representation of military reality.

Abstract (sommario):

"Objectives—Linking national survey data with administrative data sources enables researchers to conduct analyses that would not be possible with each data source alone. Recently, the Data Linkage Program at the National Center for Health Statistics (NCHS) released updated Linked Mortality Files, including the National Health and Nutrition Examination Survey data linked to the National Death Index mortality files. Two versions of the files were released: restricted-use files available through NCHS and Federal Statistical Research Data Centers and public-use files. To reduce the reidentification risk, statistical disclosure limitation methods were applied to the public-use files before they were released. This included limiting the amount of mortality information available and perturbing cause of death and follow-up time for select records. Methods—To assess the comparability of the restricted-use and public-use files, relative hazard ratios for all-cause and cause-specific mortality using Cox proportional hazards models were estimated and compared. Results—The comparative analysis found that the two data files yield similar descriptive and model results. Suggested citation: Mirel LB, Zhang C, Cox CS, Ye Y, El Burai Félix S, Golden C.
