The problem of this study was to analyze the effect that a legislature-mandated quarter system was having on certain selected middle schools in the State of Texas, Some educators have claimed that the quarter system makes it possible to add flexibility to school programs. This study, therefore, was an attempt to find out if local school districts were taking advantage of this opportunity. A second goal of the study was to determine how principals, teachers, and curriculum directors felt about the manner in which schools were implementing certain teaching strategies which experts in this field have recommended for use in middle schools. It was concluded that the schools were not taking advantage of the quarter system in order to more nearly approach the middle school concept. Educators do not seem to be against the innovations proposed by middle school authorities so it would seem that the time is right for a full commitment to the area of schooling for the middle years. The support of the general public then will be a key factor in the success of the middle school. Educators must make an effort to keep the public better informed about the way children learn and grow if this support is to be forthcoming.

abstract: The primary function of the medium access control (MAC) protocol is managing access to a shared communication channel. From the viewpoint of transmitters, the MAC protocol determines each transmitter's persistence, the fraction of time it is permitted to spend transmitting. Schedule-based schemes implement stable persistences, achieving low variation in delay and throughput, and sometimes bounding maximum delay. However, they adapt slowly, if at all, to changes in the network. Contention-based schemes are agile, adapting quickly to changes in perceived contention, but suffer from short-term unfairness, large variations in packet delay, and poor performance at high load. The perfect MAC protocol, it seems, embodies the strengths of both contention- and schedule-based approaches while avoiding their weaknesses. This thesis culminates in the design of a Variable-Weight and Adaptive Topology Transparent (VWATT) MAC protocol. The design of VWATT first required answers for two questions: (1) If a node is equipped with schedules of different weights, which weight should it employ? (2) How is the node to compute the desired weight in a network lacking centralized control? The first question is answered by the Topology- and Load-Aware (TLA) allocation which defines target persistences that conform to both network topology and traffic load. Simulations show the TLA allocation to outperform IEEE 802.11, improving on the expectation and variation of delay, throughput, and drop rate. The second question is answered in the design of an Adaptive Topology- and Load-Aware Scheduled (ATLAS) MAC that computes the TLA allocation in a decentralized and adaptive manner. Simulation results show that ATLAS converges quickly on the TLA allocation, supporting highly dynamic networks. With these questions answered, a construction based on transversal designs is given for a variable-weight topology transparent schedule that allows nodes to dynamically and independently select weights to accommodate local topology and traffic load. The schedule maintains a guarantee on maximum delay when the maximum neighbourhood size is not too large. The schedule is integrated with the distributed computation of ATLAS to create VWATT. Simulations indicate that VWATT offers the stable performance characteristics of a scheduled MAC while adapting quickly to changes in topology and traffic load. / Dissertation/Thesis / Ph.D. Computer Science 2013

The irrigation depths were applied based on daily readings of a Class A Pan, plus a leaching fraction of 20%. The considered treatments were: bare soil, soil cultivated with cabbage and soil cultivated with cabbage using mulch, adopting irrigation interval one of 24 hour. Moisture content was evaluated at two depths, being verified variation among the depths evaluates along the crop development stages, although presenting reduced variation as a function of the mulch presence. The irrigation intervals of the 12, 24 end 48 hours have not producedsignificant effect, regarding soil water retention. / O objetivo deste trabalho foi avaliar o comportamento da umidade do solo em uma área experimental cultivada com repolho, submetido a diferentes turnos de rega, no semi-árido Pernambucano. As lâminas de irrigação foram aplicadas a partir de leituras diárias de Tanque Classe “A”, e considerando uma fração de lixiviação de 20%. Os tratamentos considerados foram: solo descoberto, solo cultivado com repolho e solo cultivado com repolho na presença de cobertura morta, utilizando um intervalo de irrigação de 24 horas. A umidade foi avaliada em duas profundidades, constatando-se variação entre as profundidades avaliadas ao longo dos estádios de desenvolvimento da cultura, embora tenham apresentado pouca variação em função da presença ou ausência da cobertura morta. Os intervalos de irrigação de 12, 24 e 48 horas não diferiram significativamente, no tocante à retenção de água no solo.

Functional communication training (FCT) is an effective procedure to teach a functional communication response (FCR) and decrease problem behavior. However, there are limitations to FCT. These limitations include excessive manding (e.g., requesting items at a high rate) and manding at inappropriate times (e.g., requesting attention when caregiver is driving). Multiple schedules using static signals (e.g., colored cards) have been used to decrease these limitations while maintaining appropriate levels of the FCRs and low levels of problem behavior. Moreover, dynamic signals have been used to maintain low levels of problem behavior and appropriate levels of alternative responses outside of a multiple schedule format. Presently, no research has examined the comparison of static and dynamic signals to address the limitations of FCT. Therefore, the purpose of the current study is to compare the effects of static and dynamic signals (i.e., Time Timer®) during multiple schedules consisting of reinforcement and extinction components following FCT. Key words: functional communication training, multiple schedules, static signals, Time Timers®

Two groups of human subjects pressed buttons on five different variable-interval (VI) reinforcement schedules presented for seven minutes each for 15 sessions. At session 16, the same VI schedules were programmed concurrently in each session either with or without a 5 s changeover delay (COD). The same schedule-correlated stimuli were employed in single and concurrent conditions. Two other groups responded on concurrent VI VI conditions from the first session with or without the COD. Response allocations under concurrent scheduling better approximated relative reinforcement frequencies when the COD was programmed. Subjects with single VI histories failed to match response and time allocations to reinforcement ratios better than subjects given no such history. Bidirectional cumulative records are discussed as a molecular data analysis technique.
