This text explains the characteristics of Acre's educational policy (1999-2010) and its impact on state capacity and equity. The conception of public policy was based on Arretche (1998) and Palumbo (1989). To characterize the policy, interviews were carried out with implementing agents in 2014, data treated by content analysis. State capacity was defined based on Souza (2017), Souza and Fontanelli (2020) and Gomide and Boschi (2016). In order to verify equity, in the light of Fraser (2007) and Dubet (2008) we analyzed: policy strategies and the evolution of enrollment of indigenous and rural populations; and Saeb student proficiency data from 1999, 2005, and 2011 by gender, race, and social class, based on Crahay (2000). The characteristics of the policy include: i) Organization and planning; ii) guarantee of basic operating conditions; iii) coordination of pedagogical practices; iv) meeting the needs of population diversity and strengthening local identities; v) negotiation processes. These characteristics indicate the expansion of state capacity in Acre in the period. Strategies supported by principles of recognition justice favoring excluded populations. Analysis of student proficiency differences between social groups indicates broadening gender equity.

AbstractDrawing on our Associative-Propositional Evaluation (APE) Model, we argue for the usefulness of distinguishing between basic operating principles of learning processes (associative linking vs. propositional reasoning) and secondary features pertaining to the conditions of their operation (automatic vs. controlled). We review empirical evidence that supports the joint operation of associative and propositional processes in the formation of new associations.

Gradient Gel Electrophoresis

The wastewater generated from the processes of recovering precious metals from industrial wastes contains high concentrations of acids such as nitric acid and of salts. Biological nitrogen removal from this wastewater was attempted by using a circulating bioreactor system equipped with an anoxic packed bed or an anoxic fluidized bed and an aerobic three-phase fluidized bed. The system was found to effectively remove nitrogen from the diluted wastewater (T-N; 1,000–4,000 mg litre−1). The microbial population structure of activated sludge in an anoxic reactor was analyzed by denaturing gradient gel electrophoresis (DGGE) of PCR-amplified 16S ribosomal DNA (rDNA) fragments. DGGE analysis under different operating conditions demonstrated the presence of some distinguishable bands in the separation pattern, which were most likely derived from many different species constituting the microbial communities. Furthermore, the population diversity varied in accordance with the nitrate-loading rate, water temperature and reactor condition. Some major DGGE bands were excised, reamplified and directly sequenced. It was revealed that the dominant population in the anoxic reactor were affiliated with the β subclass of the class Proteobacteria.

This article presents the results of IoT network modeling as an ad hoc network. The main attention is paid to the features of the functioning of such a network in highdensity conditions (up to 1 device per square meter). The paper presents the results of evaluations of the basic operating conditions, namely, the level of interference from neighboring network nodes and the signal-noise ratio (SNR). The developed models make it possible to express the dependence of the noise level and SNR on the network density, produced traffic, and transmitter power. Представлены результаты моделирования сети интернета вещей как ad hoc сети. Основное внимание уделяется особенностям функционирования такой сети в условиях высокой плотности (до 1 устройства на 1 м2). Приводятся результаты оценок главных условий функционирования: помех от соседних узлов сети и отношений сигнал/шум (SNR). Показано, что подобная сеть может сохранять связность, но только при построении относительно длинных маршрутов. Установлено, что разработанные модели позволяют определить зависимость уровня помех и SNR от плотности сети, производимого трафика и мощности передатчиков.

Inclusion Model

Normative management behaviors have resulted in the patterns of today—a lack of equity in leadership positions and policies that are less favorable toward women. Meanwhile, public service values, such as respect, equity, diversity, and inclusiveness, are central foci among the professional standards and norms within the public administration field, its academic discipline and related curricula. Consequently, public administration educational programs are uniquely situated to espouse these values in their core curricula, as well as enact and reinforce them through inclusive pedagogical practices. This paper has two aims. First, to introduce the Diversity Inclusion Model, which provides a framework for examining diversity and inclusion in course design and syllabi to identify areas of improvement. Second, to apply the Diversity Inclusion Model to gender equity and inclusion to develop more gender-inclusive, acculturated learning experiences that reinforce gender equity in the classroom. This may subsequently inform the practice of public administration to re-shape professional norms and create better gender equity.

This article presents partial results from the master’s degree research developed in the Post-Graduation in Education program in Universidade Federal de São Carlos (UFSCar) -Sorocaba Campus. Having as object of study the pedagogical practice of the researcher and three teachers of early childhood education, the research seeked the answer for the following questioning: what perceptions of gender reveal themselves in the pedagogical practices of the early childhood education teachers? To answer such question, the study structured itself in the qualitative perspective and used as data production the construction of narratives (oral and written) starting from photographies of the pedagogical practices of the teachers that participated in theresearch. The results evidence that the perceptions about genders of the researched teachers in some moments demonstrate to prioritize biological aspects, in others, social ones, however, there is, on their part, the conscious intention to break up with some hegemonic models and to promote practices promoters of gender equity.

The National Council of Teachers of Mathematics recognizes that mathematical knowledge is essential for employment and full participation in our society. The strategic inclusion of the Equity Principle in NCTM's Principles and Standards for School Mathematics (2000) reflects the need in the mathematics education community to eliminate long-standing disparities in mathematics performance. However, incorporating equitable pedagogical practices into one's instruction does not mean that every student should receive identical instruction; rather, it “demands that reasonable and appropriate accommodations be made as needed to promote access and attainment [of mathematics knowledge] for all students” (NCTM 2000, p. 12).

The hydro-mechanical continuously variable transmission (HMCVT) is a critical component of the power transmission system in a tractor. However, the complexity of the operating conditions imposes high requirements on the transmission characteristics. To improve the powerful performance and economy of HMCVTs and satisfy the operational demands of high-powered tractors, a new optimization design method for the characteristic parameters of an HMCVT is proposed. First, the characteristics of an HMCVT are modeled, and the influence of the structural parameters on the transmission characteristics is analyzed. Then, HMCVT performance evaluation indexes are formulated. In accordance with the speed regulation of system, power performance, and economy characteristics, a multi-objective optimization mathematical model is established, and an improved fast non-dominated sorting genetic algorithm (INSGA-II) is designed. The introduction of a normal distribution crossover operator (NDX) and an improved adaptive adjustment mutation operator not only ensures the population diversity but also improves the Pareto solution convergence properties during the process of genetic evolution. The superiority of INSGA-II is verified by comparison with a traditional multi-objective genetic algorithm. Finally, the optimization results show that the torque ratio is increased by approximately 2.81%, 14.32%, 2.31%, and 15.07% in HM1, HM2, HM3, and HM4 respectively. The transmission efficiency is increased by approximately 3.48% and 1.97% in HM1 (HM3) and HM2 (HM4). Also, INSGA-II finds the optimal solution with a faster speed and shorter optimization time than MULGA. This research can serve as a reference for the design and optimization of HMCVTs for high-powered tractors.

Autoethnography allows us to “go beyond simply looking at the artifacts or just the surface and to focus much more on the personal, the hidden, and the less obvious” (Lapidus, Kaveh, & Hirano, 2013, p. 34), and it is becoming more important to illustrate a constructive relationship between diverse professional communities, as English as a global language acquire local identities and local professional communities develop socially situated pedagogical practices (Canagarajah, 2012). This paper explores identity negotiation of the author, a transnational EAL student and a teacher through an autoethnography. Using concept of “audibility”, “agency”, “nobody”, and “somebody” (Kettle, 2005) and communities of practice (Lave & Wenger, 1991; Wenger, 1998), this paper unpacks the complexity of identity negotiation of an EAL student, and how it affected her teaching. It also provides an opportunity to rethink the definition of success.

Resolution Structure

The extended crystallographic defects introduced into some oxide catalysts under operating conditions may be a consequence and accommodation of the changes produced by the catalytic activity, rather than always being the origin of the reactivity. Operation without such defects has been established for the commercially important tellurium molybdate system. in addition it is clear that the point defect density and the electronic structure can both have a significant influence on the chemical properties and hence on the effectiveness (activity and selectivity) of the material as a catalyst. SEM/probe techniques more commonly applied to semiconductor materials, have been investigated to supplement the information obtained from in-situ environmental cell HVEM, ultra-high resolution structure imaging and more conventional AEM and EPMA chemical microanalysis.

The coherence of the electron flux of a transmission electron microscope (TEM) limits the direct application of deconvolution techniques which have been used successfully on unmanned spacecraft programs. The theory assumes noncoherent illumination. Deconvolution of a TEM micrograph will, therefore, in general produce spurious detail rather than improved resolution.A primary goal of our research is to study the performance of several types of linear spatial filters as a function of specimen contrast, phase, and coherence. We have, therefore, developed a one-dimensional analysis and plotting program to simulate a wide 'range of operating conditions of the TEM, including adjustment of the:(1) Specimen amplitude, phase, and separation(2) Illumination wavelength, half-angle, and tilt(3) Objective lens focal length and aperture width(4) Spherical aberration, defocus, and chromatic aberration focus shift(5) Detector gamma, additive, and multiplicative noise constants(6) Type of spatial filter: linear cosine, linear sine, or deterministic
