Geologic Analysis of Primary and Secondary Tight Gas Sand Objectives, Phase C

Previous assessments of blanket-geometry tight gas sandstones led to the selection of the Travis Peak Formation of the East Texas and North Louisiana Basins and the Corcoran and Cozzette Sandstones of the Piceance Creek Basin as major research objectives. The anticipated outcomes of this study include increased availability of tight gas resources and advancements in technology with high transferability. The work reported here encompasses all aspects of the depositional systems and reservoir geology of these units as fundamental components of resource characterization, with an emphasis on understanding controls on reservoir facies distribution and their relevance to low-permeability reservoir development. Six lithofacies of the Travis Peak (Hosston) Formation in East Texas and North Louisiana have been identified using electric logs. These facies comprise sand-rich fluvial-deltaic, silt-rich delta-front, clay- and carbonate-rich shelf, carbonate reef, and clay-rich open marine facies. The most well-developed facies in the East Texas area are the fluvial-deltaic and delta-front facies. Travis Peak rocks from the Clayton Williams #11 Sam Hughes well, Panola County, Texas, were primarily deposited in a fluvial environment within a coastal plain setting. Porosity and permeability control in the clean sandstones are primarily attributed to quartz overgrowths, chlorite cement, and solid organic matter, with approximately half of the remaining porosity being secondary, resulting from framework grain dissolution. Studies of Travis Peak gas production at Pinehill Southeast and Percy-Wheeler fields indicate an average permeability-thickness product of about 10 md-ft, with a range of 0.7 to 35 md-ft, indicating dry gas reservoirs. Well logs, core, and mud logs from Chapel Hill field in Smith County, Texas, were examined in preparation for a complete cooperative well program in the ARCO #11 Phillips well on the western margin of that field. Field studies of Corcoran-Cozzette Sandstones near Grand Junction, Colorado, suggest that the depositional environments of the Corcoran evolved from marine upper shoreface to non-marine, while the Cozzette sequence evolved from lower to upper shoreface. Porosity and water saturation calculations have been conducted by computer for seven Corcoran and Cozzette depositional units. A comparison of calculated water saturation with core-derived porosity and permeability indicates a fair to very good correlation of reservoir properties with clay content measured by gamma-ray log.Bureau of Economic Geolog

Influencer: The New Science of Leading Change

What qualifies people to be called “leaders” is their capacity to influence others to change their behavior in order to achieve important results. Problems ultimately call for the ability to change what people do. FOCUS AND MEASURE Start change with a clear and compelling statement of the goal you’re trying to achieve Measure your progress; Measure the right thing and measure it frequently to Influence. FIND VITAL BEHAVIORS Changing vital behaviors leads to change; It takes only a few behaviors to create big change; Notice the obvious; Look for crucial moments; Learn from positive deviants; Spot cultural busters. ENGAGE ALL SIX SOURCES OF INFLUENCE Find ways to get people to actually carry out the vital behaviors needed for change. Influencers succeed in creating change because they overdetermine success using all six sources of influence (Personal Motivation, Personal Ability, Social Motivation, Social Ability, Structural Motivation, and Structural Ability).American Association for Agricultural Education USDA Hatch Project TEX 09890 "The Adoption Impact of Food and Agricultural Sciences Curricula on Public Health

Les messages : eux et nous

Au cours de l'hiver 1971, dans le cadre d'un enseignement de communication de masse, les étudiants ont fabriqué trois émissions de télévision d'une demi-heure chacune, après un stage intensif d'entraînement aux techniques audio-visuelles. Ces émissions ont été diffusées sur le canal 9 (câble) les mardi soir à 19 heures 30, pendant trois semaines consécutives. Les étudiants se sont alors rendus dans des familles à l'écoute, pour vérifier sur place l'effet de leur propre message. Nous avons recueilli quelque soixante-dix heures d'entrevues qui devaient porter sur les émissions. Le matériel est de nature spontanée, malgré un schéma général d'entrevue. Pour trouver les informateurs, nous sommes partis d'un échantillon de 900 personnes, tiré parmi les 90,000 abonnés du câble, et classé ensuite selon l'indice socio-économique du secteur de recensement où se trouve le domicile (indice de Schefsky). Nous avons d'abord sélectionné les familles du centre de la distribution pour éviter les variations qu'on ne pouvait analyser, à cause du nombre restreint de familles à étudier (quinze). Nous avons choisi des familles complètes avec adolescent. Obtenir des collaborateurs s'est avéré très difficile, d'abord parce que le câble dessert une population qui risque d'offrir des caractéristiques particulières : célibataires, personnes âgées, invalides, travailleurs de nuit, langue maternelle autre que français ou anglais, etc. De plus, la collaboration était onéreuse, puisque les familles devaient nous consacrer quatre soirées. En fait, le choix s'est déplacé du centre vers la distribution des mieux nantis ; nous avons atteint le middle mass, avec quatre ouvriers spécialisés, trois employés de bureau, un fonctionnaire, un représentant de compagnie, mais aussi un chômeur et trois ouvriers non qualifiés (deux non spécifiés). La moyenne de scolarisation est de dix années d'études, la majorité des pères de familles ayant complété une neuvième année. Cette population ne représente donc pas ce qu'il est convenu d'appeler « les défavorisés », i.e. ceux qui n'ont qu'un cours primaire et auxquels s'adresse un programme comme Multi-Media ; il s'agit toutefois d'une « vraie » population. Nous avons ainsi pu réfléchir sur des données vivantes, plutôt qu'à partir de nos pré-conceptions. On ne saurait toutefois parler de savoir accumulé car, à notre connaissance, aucun résultat de recherche sur le processus global de communication de masse auprès de la population réelle n'a jamais été publié

Men and Women Exhibit a Differential Bias for Processing Movement versus Objects

Sex differences in many spatial and verbal tasks appear to reflect an inherent low-level processing bias for movement in males and objects in females. We explored this potential movement/object bias in men and women using a computer task that measured targeting performance and/or color recognition. The targeting task showed a ball moving vertically towards a horizontal line. Before reaching the line, the ball disappeared behind a masking screen, requiring the participant to imagine the movement vector and identify the intersection point. For the color recognition task, the ball briefly changed color before disappearing beneath the mask and participants were required only to identify the color shade. Results showed that targeting accuracy for slow and fast moving balls was significantly better in males compared to females. No sex difference was observed for color shade recognition. We also studied a third, dual attention task comprised of the first two, where the moving ball briefly changed color randomly just before passing beneath the masking screen. When the ball changed color, participants were required only to identify the color shade. If the ball didn't change color, participants estimated the intersection point. Participants in this dual attention condition were first tested with the targeting and color tasks alone and showed results that were similar to the previous groups tested on a single task. However, under the dual attention condition, male accuracy in targeting, as well as color shade recognition, declined significantly compared to their performance when the tasks were tested alone. No significant changes were found in female performance. Finally, reaction times for targeting and color choices in both sexes correlated highly with ball speed, but not accuracy. Overall, these results provide evidence of a sex-related bias in processing objects versus movement, which may reflect sex differences in bottom up versus top-down analytical strategies

The influence of visual feedback and gender dynamics on performance, perception and communication strategies in CSCW

The effects of gender in human communication and human-computer interaction are well-known, yet little is understood about how it influences performance in the complex, collaborative tasks in computer-mediated settings – referred to as Computer-Supported Collaborative Work (CSCW) – that are increasingly fundamental to the way in which people work. In such tasks, visual feedback about objects and events is particularly valuable because it facilitates joint reference and attention, and enables the monitoring of people’s actions and task progress. As such, software to support CSCW frequently provides shared visual workspace. While numerous studies describe and explain the impact of visual feedback in CSCW, research has not considered whether there are differences in how females and males use it, are aided by it, or are affected by its absence. To address these knowledge gaps, this study explores the effect of gender – and its interactions within pairs – in CSCW, with and without visual feedback. An experimental study is reported in which mixed-gender and same-gender pairs communicate to complete a collaborative navigation task, with one of the participants being under the impression that s/he is interacting with a robot (to avoid gender-related social preconceptions). The study analyses performance, perceptions and communication strategies. As predicted, there was a significant benefit associated with visual feedback in terms of language economy and efficiency. However, it was also found that visual feedback may be disruptive to task performance, because it relaxes the users’ precision criteria and inflates their assumptions of shared perspective. While no actual performance difference was found between males and females in the navigation task, females rated their own performance less positively than did males. In terms of communication strategies, males had a strong tendency to introduce novel vocabulary when communication problems occurred, while females exhibited more conservative behaviour. When visual feedback was removed, females adapted their strategies drastically and effectively, increasing the quality and specificity of the verbal interaction, repeating and re-using vocabulary, while the behaviour of males remained consistent. These results are used to produce design recommendations for CSCW systems that will suit users of both genders and enable effective collaboration

Short-Term Enrichment Makes Male Rats More Attractive, More Defensive and Alters Hypothalamic Neurons

Innate behaviors are shaped by contingencies built during evolutionary history. On the other hand, environmental stimuli play a significant role in shaping behavior. In particular, a short period of environmental enrichment can enhance cognitive behavior, modify effects of stress on learned behaviors and induce brain plasticity. It is unclear if modulation by environment can extend to innate behaviors which are preserved by intense selection pressure. In the present report we investigate this issue by studying effects of relatively short (14-days) environmental enrichment on two prominent innate behaviors in rats, avoidance of predator odors and ability of males to attract mates. We show that enrichment has strong effects on both the innate behaviors: a) enriched males were more avoidant of a predator odor than non-enriched controls, and had a greater rise in corticosterone levels in response to the odor; and b) had higher testosterone levels and were more attractive to females. Additionally, we demonstrate decrease in dendritic length of neurons of ventrolateral nucleus of hypothalamus, important for reproductive mate-choice and increase in the same in dorsomedial nucleus, important for defensive behavior. Thus, behavioral and hormonal observations provide evidence that a short period of environmental manipulation can alter innate behaviors, providing a good example of gene-environment interaction

La «Révolution française » : un rapport commercial à l'histoire et à la démocratie

Twenty years later, amid the hoopla of the French Revolution 's bicentennial, the author traces the hsitory of a Quebec popular 1960s rock groups, known as the Sinners, and later as the Révolution française ! Their story illustrates how a grouip that attempst to be creative must constantly negotiate between multiple forces that are manifest both as its own priorities and oas the oppotunities it encounters.Une vingtaine d'années plus tard, dans la foulée des célébrations du bicentenaire de la Révolution française, l 'auteur suit à la trace un groupe rock, populaire au Québec entre 1966 et 1970, d'abord appelé les Sinners, puis... la Révolution française ! L'exposé de leur cheminement tortueux et de leurs mille facettes permet d'observer comment un groupe qui se veut créateur par ses produits culturels, en l'occurrence ses disques, doit constamment s 'ajuster en fonction de forces multiples qui se manifestent parfois comme les pressions de ses voix intérieures, parfois comme l'attraction de voies extérieures.En medio de un sinnúmero de celebraciones del bicentenario de la revolución francesa, el autor de este artículo sigue la huella de un grupo de rock, popular en Quebec entre 1966 y 1970 ; el nombre inicial del grupo era Sinners y después La Revolución Francesa. La presentación que hace el autor del camino tortuoso así como de las mil facetas de este grupo, permite observar como un grupo que pretende ser creador en sus producciones culturales, en este caso sus discos, debe adaptarse a fuerzas múltiples que se manifiestan a veces por inspiración artística o a veces por la atracción del éxito comercial.Saucier Robert.

De la lanterne magique à la télévision : oscillations des discours et des usages sociaux

The author reflects upon the disparity between the discourse and the actual social usages of technology. A parallel is drawn between discourses promoting and regulating the social use of two technologies, television and the magic lantern. Three successive discourses on the development of television in Québec are identified. The author concludes that the uses of technology cannot be imposed, as they result from a complex dialectic between technologists and users.L'auteur nous présente une réflexion sur le déphasage entre le discours sur les nouvelles technologies et l'usage social effectif de celles-ci. Puisant dans l 'histoire, il tire un parallèle entre le discours édifiant deux nouveaux objets techniques, la lanterne magique et la télévision, et la mise en place des normes d'usage régissant leurs pratiques. Après avoir identifié les trois discours qui successivement ont marqué «les pérégrinations des discours et des usages par rapport à la télévision au Québec», l'auteur conclut qu 'on ne peut imposer un usage particulier d'un nouvel objet technique : celui-ci est toujours le résultat d 'une «dialectique complexe» entre les technologues et les usagers.El autor nos presenta una reflexion sobre el defasaje entre el discurso relacionado a las nuevas tecnologías y el uso social efectivo de éstas. El autor hace un paralelo entre el discurso valorizante de dos nuevos objetos técnicos, en el momento histórico de su aparición, la linterna mágica, la televisión y el discurso sobre la definición de las normas que reglamentan su utilización. Después de haber identificado los tres discursos que han marcado sucesivamente «las peregrinaciones de los discursos y de las utilizaciones de la televi¬ sión en Quebec», el autor conluye que no se puede imponer un uso particular de un nuevo objeto técnico : este es siempre el resultado de una «dialéctica compleja» entre los tecnólogos y los utilizadores.Saucier Robert.
