The program for the management of the water and soil (PROMAS) is a research department of the University of Cuenca. It focuses on the monitoring and conservation of the water sources and natural resources. Among others, such program mainly requires the monitoring of several variables by means of a set of hydro-meteorological stations. From its beginning, the program has deployed around 130 stations in an extensive geographic area of interest, ranging from the Cajas sector in the province of Azuay to the province of Cañar. Currently, the meteorological stations stores the variables of interest in their internal memory. Then, the analysis of the collected data requires the physical displacement of the Promas staff to the different sites. Due to the fact that most of the remote sites are of difficult access, the personal obtain the information with a periodicity of around 30 and 45 days. In this context, this paper describes the work on progress whose main objective is to provide to the meteorological stations with the wireless transmission capacity of the data collected by the sensors to the Promas data center in real time.

Meteorological radar networks are suited to remotely provide atmospheric precipitation retrieval over a wide geographic area for severe weather monitoring and near-real-time nowcasting. However, blockage due to buildings, hills, and mountains can hamper the potential of an operational weather radar system. The Abruzzo region in central Italy’s Apennines, whose hydro-geological risks are further enhanced by its complex orography, is monitored by a heterogeneous system of three microwave radars at the C and X bands with different features. This work shows a systematic intercomparison of operational radar mosaicking methods, based on bi-dimensional rainfall products and dealing with both C and X bands as well as single- and dual-polarization systems. The considered mosaicking methods can take into account spatial radar-gauge adjustment as well as different spatial combination approaches. A data set of 16 precipitation events during the years 2018–2020 in the central Apennines is collected (with a total number of 32,750 samples) to show the potentials and limitations of the considered operational mosaicking approaches, using a geospatially-interpolated dense network of regional rain gauges as a benchmark. Results show that the radar-network pattern mosaicking, based on the anisotropic radar-gauge adjustment and spatial averaging of composite data, is better than the conventional maximum-value merging approach. The overall analysis confirms that heterogeneous weather radar mosaicking can overcome the issues of single-frequency fixed radars in mountainous areas, guaranteeing a better spatial coverage and a more uniform rainfall estimation accuracy over the area of interest.

OBJECTIVES/SPECIFIC AIMS: As the issues facing our global society become more complex, university faculty are called upon to address these contemporary problems using interdisciplinary approaches. But do reappointment, promotion, and tenure (RPT) guidelines reflect and reward this fundamental change in the nature of higher education and scholarly inquiry? After collecting all of the RPT guidelines across the university, our research team at the University of Cincinnati (UC) conducted a content analysis of these documents to determine how collaborative work is defined, interpreted, and supported. In addition, we also sought to identify differences in how collaborative work is valued across disciplines and how that value has changed over time. METHODS/STUDY POPULATION: An initial database was assembled that included two distinct data samples: historical and current. Both included RPT criteria for over 100 disciplinary units at the university. Working with the initial comprehensive database, the team narrowed content by selecting all language related to collaborative work using several relevant keywords or keyword fragments (team, collaborat[*], disciplin[*], and interprofessional). This process resulted in a subset of data reflecting the area of interest that could then be coded. Three investigators independently coded common portions of the data for categories. The investigators met regularly to compare the results of their coding, and discrepancies between the investigators’ coding schemes were resolved through discussion. The final, common coding scheme will used to code the remainder of the data by each independent investigator. The team meets weekly to discuss significant passages and assign codes, and then reach consensus related to important themes that are identified. Specifically, we will examine the frequency with which collaborative activities are included, the value and emphasis given to them, and the differences across units. Having a historical sample and a current sample also allows us to analyze trends over time and further compare disciplinary differences. RESULTS/ANTICIPATED RESULTS: UC is a diverse institution that includes world-renowned creative schools (the College Conservatory of Music and the College of Design, Architecture, Art, and Planning), as well as traditional colleges of medicine, nursing, pharmacy, allied health, engineering, business, arts and sciences, etc. UC also includes two branch campuses that specialize in associate’s degree level education. Given the diversity in educational and research missions across these areas, we anticipate discovering several themes within the RPT guidelines, primarily centered around the traditional foundations of faculty work such as service, research, and teaching. We anticipate strong differences by college and disciplinary focus, with emphasis on collaborative work and engagement increasing as RPT guidelines become more current. DISCUSSION/SIGNIFICANCE OF IMPACT: Our experience is that faculty members want to engage in collaborative work when possible and appropriate, but their perception is that independent contributions to their field are more highly valued than interdisciplinary work. As universities rush to endorse and promote interdisciplinary, team-oriented research and teaching, this study will afford a better understanding of the types of activities valued at one large and diverse urban institution, grounded in the actual language of RPT criteria.

Energy Conservation Measures (ECMs) of the primary data center at the University of Maryland are developed. Measurement and simulation are performed to validate the developed ECMs. Three ECMs — 1) Increase in the return temperature at Computer Room Air Conditionings (CRACs) 2) Cold aisle containment 3) Elimination of unnecessary CRACs — are suggested to reduce energy consumption by optimizing the thermo-fluid flow in the data center. Power savings of 12.7 kW – 17.4 kW and 14.1 kW are obtained by increasing the return air temperatures at the CRACs and performing the cold aisle containment, respectively. In addition, a power saving of 11.2 kW is obtained by turning off CRACs 3 and 8 which have an adverse effect on the data center cooling.

In 1926 students enrolled in Mexico City’s exclusive Catholic preparatory schools faced a crisis that threatened to ruin their academic careers. They were in a serious quandary because officials at the government-supported National Autonomous University of Mexico (UNAM) were placing what were viewed as unfair obstacles to their plans of matriculating into the university, thereby threatening the aspirations that these students and their parents had for their futures. Their predicament was directly related to the deteriorating political climate that would soon produce the religious civil war known as the Cristero Rebellion of 1926-1929. These students were being victimized by pro-government UNAM officials because of their Catholic Church affiliation; this at a time that the Church was locked in a bitter struggle with President Plutarco Elías Calles (1924-1928). The heart of the conflict was Calles’s steadfast determination to enforce the anticlerical provisions contained in the Constitution of 1917. This landmark document encapsulated many of the central demands of the men and women who, like President Calles, had fought in the Mexican Revolution (1910-1920). Calles was a dedicated anticlerical who believed that the nation’s social, political, economic, and educational development required a dramatic reduction in the Roman Catholic Church’s influence within Mexican society. By mid 1926 these affected students had organized themselves into a citywide student group, the Union of Private School Students, with the goal of defending themselves from what they perceived to be the arbitrary, ideologically driven actions of university officials. However, the evolution of this nascent student organization changed dramatically when its activities drew the attention and interest of the country’s most important Catholic official, the Archbishop of Mexico José Mora y del Río.

This article provides an analysis of data obtained from the first 2 years of Project SPECTRE, a federally funded in-service training program for regular classroom teachers drawn from southern Nevada's remote, sparsely populated schools. Project SPECTRE was designed to assess the relative cost effectiveness of four types of in-service approaches, including instruction through independent study, by master teachers employed by the school district and by university instructors either on the university campus or on site. The 2-year results indicate that direct instruction of any sort produces gains in knowledge acquisition significantly superior to those obtained through independent study. In spite of its relatively lower initial costs, independent study was also found to be less cost effective than the direct-instructional approaches. Finally, of the three direct-instructional approaches, using university personnel in remote sites was found to be the most cost effective, followed, respectively, by the master-teacher and university-campus approaches.

British theatre between the two world wars has been a neglected area of interest for contemporary scholars and theatre historians, but a growing body of work in this field has of late begun to challenge the orthodoxies. Much of the new work has focused on the reclamation and repositioning of the work of ‘forgotten’ women playwrights and commercially successful gay playwrights such as Noël Coward and Terence Rattigan. Here, John Deeney examines how the Lord Chamberlain's licensing of Christa Winsloe's lesbian-themedChildren in Uniform, and the commercial and critical success of its production at the Duchess Theatre in 1932–33, invites a reassessment of the possibilities open to women playwrights for exploring ‘deviancy’; and how contemporary theoretical positions too frequently ignore the challenge of the historically and culturally specific. John Deeney is Lecturer and Course Director in Theatre Studies at the University of Ulster at Coleraine. He is the editor ofWriting Live: an Investigation of the Relationship between Writing and Live Art(New Playwrights Trust, 1998) and a contributor to the forthcomingWomen, Theatre and Performance: New Histories/New Historiographies(Manchester University Press) andBritish Theatre between the Wars(Cambridge University Press).

This paper discusses the stochastic and strategic control of 60 GHz millimeter-wave (mmWave) wireless transmission for distributed and mobile virtual reality (VR) applications. In VR scenarios, establishing wireless connection between VR data-center (called VR server (VRS)) and head-mounted VR device (called VRD) allows various mobile services. Consequently, utilizing wireless technologies is obviously beneficial in VR applications. In order to transmit massive VR data, the 60 GHz mmWave wireless technology is considered in this research. However, transmitting the maximum amount of data introduces maximum power consumption in transceivers. Therefore, this paper proposes a dynamic/adaptive algorithm that can control the power allocation in the 60 GHz mmWave transceivers. The proposed algorithm dynamically controls the power allocation in order to achieve time-average energy-efficiency for VR data transmission over 60 GHz mmWave channels while preserving queue stabilization. The simulation results show that the proposed algorithm presents desired performance.
