Abstract High-resolution subsurface seismic imaging that places sources and receivers in wellbores is an emerging exploration technology that can help petroleum companies find and recover more oil and gas. Successful commercialization of this enabling technology requires the development of receiver arrays that can couple fifty or more three-component sensor modules to the wellbore in a reliable manner. Although electrical clamping systems have been successfully used in small arrays, hydraulic clamping is required for more than ten modules. Both inflatable-bladder and cylinder-actuated clamp arrays have been designed However, when arrays must operate in 200° C environments, elastomer bladders become unsuitable. Research at the University of Arkansas has produced a failsafe fluid power system design makes feasible the successful development of large seismic sensor arrays that can operate in deep well bores.

Background: Medical school learning communities benefit students. The College of Medicine (COM) at the University of Arkansas for Medical Sciences (UAMS) provides medical students with academic, professional, and personal support through a learning community (LC) made of 7 academic houses. Objectives: To evaluate the effectiveness of the academic house model at UAMS utilizing a mixed-methods survey. The aims were to: (1) assess student experience and satisfaction with academic houses, (2) describe the realms of advising and guidance, and (3) identify areas for improvement. Method: An online survey was assigned to 723 COM students (all students enrolled, first through fourth years) at UAMS in March 2019. The survey was comprised of 25 items (10 multiple-choice, 8 on the Likert scale, and 7 open-ended questions). Data was depicted using frequency and percentages and/or thematic review of free-form responses. Results: The survey response rate was 31% (227 students). The majority of students responding (132, 58.1%) attended 2 or more face-to-face meetings with the faculty advisor within the preceding year. However, 27 (11.9%) students did not have any meetings. Approximately two-thirds of the respondents were satisfied or very satisfied with the guidance and direction provided by their advisors [very satisfied (n = 83; 36.6%); satisfied (n = 77; 33.9%)]. Themes that emerged from student generated areas for improvement include time constraints, advisor/advisee interest mismatch, and perceived inadequacy of advising content/connections. Conclusions: This study confirms the effectiveness of the LC model for advising and mentoring in the COM at UAMS. Uniquely, this study identifies not only learners’ satisfaction with their LC but also highlights areas for improvement which are widely generalizable and important to consider for institutions with or planning to start an LC.

This article analyses the behaviour of ‘learning’ companies and ‘entrepreneurial’ universities in the context of the territorial and business ecosystems of innovation in which they are involved. Against a background of the fundamental differences between the higher education and the commercial sector, and the history of university—industry cooperation in Europe, the characteristics of territorial ecosystems for innovation (TEIs) are set out and the holistic, networking and interactive models of knowledge and technology transfer are discussed. This analysis provides a conceptual framework for the successful development of territorial ecosystems of innovation which are identified as crucial for future successful European socio-economic development. As concrete examples of activities which contribute towards this end, the authors offer brief case studies of the Economic Development Unit and Innovation Centre at the University of North London and the London Technopole Initiative.

Effective Development

В современное время нефтегазовая отрасль обладает большим потенциалом для развития экономики, благодаря чему ее регулированию уделяется внимание на международном уровне. К примеру, стоит упомянуть Организацию стран - экспортеров нефти, которая была создана нефтедобывающими странами в целях контроля квот добычи на нефть. Актуальность публикации заключается в том, что на сегодняшний день нефтяная отрасль продолжает оказывать значительное влияние на экономику стран, чье устойчивое развитие определяется успешным развитием нефтяной промышленности. Рассмотреть, проанализировать и обозначить, на наш взгляд, перспективы эффективного развития отраслей нефтяной промышленности Российской Федерации, по сравнению с развитием нефтяной промышленности гигантов данной отрасли - Саудовской Аравии и Соединенных Штатов Америки, явилось целью исследования в данной статье. In modern times, the oil and gas industry has great potential for the development of the economy, due to which its regulation is paid attention at the international level. For example, it is worth mentioning the Organization of Petroleum Exporting Countries, which was established by oil-producing countries to control oil production quotas. The relevance of the publication is that today the oil industry continues to have a significant impact on the economies of countries whose sustainable development is determined by the successful development of the oil industry. To consider, analyse and outline, in our opinion, the prospects for the effective development of the oil industries of the Russian Federation, in comparison with the development of the oil industry of the following giants of this industry of Saudi Arabia and the United States of America, was the purpose of the study in this article.

The editor, M. Keith Booker, Professor of English at the University of Arkansas, has served as editor on many reference works in literature as well as many books on genres and literary movements, specific authors, and other critical works. Booker also edited the last reference work dedicated to literature and politics, Encyclopedia of Literature and Politics: Censorship, Evolution, and Writing, a three-volume set published in 2005 by Greenwood, which is surprisingly the only current reference work dedicated solely to examining the connection between literature and politics. There are many recent book-length critical works on literature and politics, but these monographs typically focus on a genre or other refined topic such as a literary movement or single author. The compact single-volume Literature and Politics Today is a welcome addition to reference work in literature and politics. Certainly, other reference works in literary criticism cover some of the topics related to the intersection of politics and literature, but do not have the political focus of Literature and Politics Today.

Study Participants

Domestic minor sex trafficking (DMST) is modern-day slavery of children and the commercial sexual abuse of children through buying, selling, or trading their sexual services.  DMST is a form of child abuse.  The victim can be any person of nationality, age, socioeconomic status, or gender. In America, throughout college campuses, a lot of students are not informed of domestic minor sex trafficking. When thinking about domestic minor sex trafficking, most people do not think that this crime happens in our country, better yet our state of Arkansas. The purpose of this study was to investigate the perceptions of college students attending the University of Arkansas at Pine Bluff on domestic minor sex trafficking in our country and in our state of Arkansas (a crime that is growing aggressively in the United States). Fifty participants who were students attending the University of Arkansas at Pine Bluff participated in the study. Participants consisted of male and female students between the ages of 18 to 25 (N = 30 Females; N = 20 Males). Survey data were analyzed using Microsoft Excel software. Participants responded to ten yes or no descriptive questions about domestic minor sex trafficking (e.g., Questions like: have you heard about domestic minor sex trafficking; and do you think child sex trafficking is an organized crime). The data yielded both quantitative and qualitative results. Results showed that female students were more knowledgeable and were more aware of DMST than males. Implications for interventions will be discussed. Further research also is suggested.
