Telemetric System

With the development of microprocessor components and, accordingly, a significant expansion of the use of computer technologies, remote measurement techniques are being developed. These include telemetry and remote control of technical systems or their components in industry, research, home appliances and other fields. In this paper, the author suggests how to build a local web-server based on a microcontroller with an ARM Cortex-M4 core, which can be interacted with via an http-browser with Internet access. The block diagram of the local web-server on the basis of the STM32F407 microcontroller with the ARM Cortex-M4 core is suggested. Hardware modeling of the local web-server with a two-processor architecture including the main controller and the Modbus processor with the RS-485 interface, which provides information exchange via the Modbus RTU protocol, is done. The main controller is equipped with an indicator system based on functionally programmable LED indicators, an LCD indicator of type BC1602A, a local keyboard, USB and SWD ports for debugging and programming of the microcontroller, an external Ethernet module providing a temperature sensor and the Modbus RTU relay module, which interacts with the main controller of the local web-server via the Modbus processor with the RS-485 interface using the Modbus RTU protocol. A software for interaction of the local web-server and a http-browser has been developed. The local web-server was tested with different types of http browsers, proved to be reliable and showed the response time which depends on the number of sensors and is less than 1 second in case of 9 sensors.

Antecedents And Consequences

This chapter provides an overview of the antecedents and consequences of gossip in work groups. First, the chapter reviews the different motives for gossip in work groups (i.e., bonding, entertainment, emotional venting, information exchange, maintenance of group norms/social order, and interpersonal aggression) and links each motive to psychological theory. Second, the chapter reviews the different types of influence that gossip can have on various indicators of group effectiveness. Reflecting on the motives underlying gossip in work groups, as well as on its outcomes, it argues that future research should start integrating the diverse insights provided by earlier research on both gossip motives and outcomes, and it provides a number of suggestions for doing so.

Assessment Procedures

The COVID-19 pandemic required academic institutions to quickly transition to online learning and make changes to assessment procedures. This study examines how a school of pharmacy creatively approached the challenge of online assessment while maintaining the standards necessary to prepare practice-ready student pharmacists. To conduct traditional exams, instructors deployed two different types of methods utilizing testing software: a video conferencing technology approach which mimicked pre-pandemic, on-campus proctored exams; or open-book, internet access-enabled exams that ensured academic integrity and rigor through various testing strategies. To assess students’ clinical skills, faculty used a combination of techniques such as physical examinations, patient interviews, and patient presentations. To understand the student experience with these assessments, students were surveyed using a 12-item questionnaire. Overall, online video proctoring maintained consistency in exam structure and administration, but required extensive instruction for both students and proctors. Students preferred unproctored, open-book, internet access-enabled, standard time exams versus proctored, closed-book, internet-access disabled, extended time exams. Changes to testing procedures, whether with proctored or unproctored methods, appeared to increase student stress.

The article is devoted to the research of the institutional foundations of interaction between agricultural advisory services and amalgamated hromadas (AH). The goal of the article is to generalize the institutional framework for cooperation between agricultural advisory services and AH. The institutional components of the state regulation of agricultural advisory services are determined. Also the main subjects among Central executive authorities for solving these issues are defined. The results of questionnaire survey to determine of aspects of attitude of the community leadership to the solution of their problem and reciprocity with advisory services are presented. Three groups of AH actual problems have been determined. In the context of realization of institution provisions is substantiated the order of advisory services for solving of these problems. The results of the research of self-government bodies readiness to participate in the financing of the agricultural advisory activity are represented. The order of solving of the priority tasks for formation of the agricultural advisory system in rural hromadas is grounded. The priority tasks are include: 1) establishment of system communications between advisory services and AH; 2) preparation of mechanisms (models) for involving of local communities in agricultural advisory activity. Rural communities can count on different types of state support on the base of cooperation with agricultural advisory. It seems expedient for the Ministry for Development of Economy, Trade and Agriculture of Ukraine to initiate the elaboration of mechanisms for state stimulation of community cooperation in the advisory sphere. The priority measures for convergence of the system of agricultural advisory and AH have been identified. It connect with coordination of activity for information exchange between executive authorities, self-government communities and subjects of agricultural advisory. This is an objective necessity and will permit to obtain a synergistic effect: increasing the ability of rural amalgamated hromadas to solve their own problems independently, improving the living standards of the rural population. An extremely relevant topic is launching of pilot projects for the development of advisory services in AH, including the use of mechanisms of inter-municipal cooperation. International technical assistance projects should be more actively involved in this work. Prospects for further research are conclude in elaboration of the specific mechanisms of cooperation between the subjects of advisory services with the AH leadership in solving of existing problems.

With the socio-economic transformation, the recombination of regional development factors and the followed reconstruction of the rural development elements system have profoundly changed the rural landscape of the Kashgar region in Northwest China. The factors affecting the rural production and lifestyle interact with each other, shaping different types of rural development. Accordingly, basing on the main factors influencing the rural development ability and long-term development potential, the assessment indicator system of rural comprehensive development (RCD) was established to reveal the differentiation of rural development and identify the dominant factors affecting rural development. The principal component analysis method and the cluster analysis method was used to distinguish the different types. The results show that the high-level rural development areas are mainly concentrated in the center of the region, while the low-level areas are mainly distributed in the periphery, with significant spatial differentiation characteristics. We divided the rural development into three categories and 11 zones for which the basic natural conditions and external challenges are different. The categories reflect three possible results of rural development: grow, decline, and vanish, which is in the industrialization development stage. With the transformation of human society and the change of urban–rural relationship in its mode and content, the external economy, society, and changing environment has put pressures on rural areas. Therefore, according to different rural development types, it is necessary to take measures to strengthen the rural areas to cope with external environmental challenges.

Magnetic Observatories

<p>In magnetic observatories the Earth’s magnetic field is continuously recorded and the acquired data are calibrated so that the evolution of the field can be studied on time scales ranging from seconds to decades. The French network (the so called BCMT) includes 18 observatories around the world and the different types of data produced are freely accessible on several data centres. We will describe a typical infrastructure of a magnetic observatory, the measurement techniques, the instruments used, the general processing applied to obtain calibrated data and finally the environmental constraints that have to be respected in order to acquire suitable data. If magnetic observatories were originally set to monitor the slow variations of the Earth’s main magnetic field, they are more and more often used for space-weather monitoring and to study signal generated in the ionosphere and magnetosphere. This new range of applications implies an evolution of the network, of the acquisition and distribution techniques. The strategy we developed to respond to these new challenges will be also presented.</p>

New Evidence

The evolution of internet access and use in Brazil in the direction of social inclusiveness and to guarantee uses that promote individual and community development is the focus of the present paper. Previous evidence on the subject initially presented indicates the prevalence of contrasting aspects: some outstanding positive initiatives and results towards democratization of the internet, as well as the maintenance of great digital inequalities. New evidence on the evolution of internet access and use is also discussed herein, based on analyses of longitudinal data obtained from the Brazilian Census Bureau’s Annual Survey (IBGE/PNAD, 2005, 2008). After describing aspects of increase in access to the internet, we focus on the evolution of different types of everyday life internet uses, particularly those that might contribute to individual and community development. How accesses and uses are gradually incorporating the less privileged sectors of the Brazilian adult population is also considered in the analyses. The results obtained reinforce the previous contrasting evidences: outstanding growth in access and in diversified uses are observed - suggesting intensive appropriation of internet technology and resources by the population - as well as the persistence of great inequalities. These circumstances indicate that the digital divide in Brazil is still a great challenge to be faced through comprehensive and long-term policies and initiatives.

Level Analysis

This paper presents findings of a recent study which explores rural women’s use of an agricultural decision support system, CottonLOGIC, within the Australian cotton industry. Meta-analysis is applied through the theoretical framework of structuration theory while diffusion theory is used for lower level analysis. The concept of communication is applicable to both theories. The significance of CottonLOGIC as a communication medium for technology transfer of industry research to cotton farms is evaluated in this paper. The findings suggest that CottonLOGIC is a recognised means of information exchange but even more valuable is the cooperation of stakeholders to influence effective reconstruction of farm management practices and technology usage.

The article discusses the issues of increasing the efficiency of irrigation of crops cultivated in agriculture. Precise irrigation is an effective solution to irrigation problems. The methods and means of intellectual irrigation, based on sensors that monitor soil moisture and provide signals to the irrigation control solenoid valve, are described. A block diagram of an automatic drip irrigation system is described. For the experiment, five different types of droppers (A, B, C, D, and E) were used Rivulis Eurodrip brand, three of which are droppers with pressure compensation and two are the droppers without pressure compensation. Three parameters were used to study the characteristics of droppers: flow uniformity; volumetric water flow depending on the inlet pressure; determination of the dropper constant and the volume flow exponent. Droppers were tested at three pressures in the system: 0.05, 0.2 and 0.35 MPa. At each pressure value, the experiment was performed in triplicate. The process of calibrating humidity sensors is described. An analysis is made of the effect of soil moisture on the electrical resistance of the sensor for various types of soils. It is recommended that moisture sensors be calibrated to local soil and water conditions.

The Relationship

Abstract This article examines the relationship among different types of nonobservation errors (all of which affect estimates from nonprobability internet samples) and between nonresponse and measurement errors. Both are examples of how different error sources can interact. Estimates from nonprobability samples seem to have more total error than estimates from probability samples, even ones with very low response rates. This finding suggests that the combination of coverage, selection, and nonresponse errors has greater cumulative effects than nonresponse error alone. The probabilities of having internet access, joining an internet panel, and responding to a particular survey request are probably correlated and, as a result, may lead to greater covariances with survey variables than response propensities alone; the biases accentuate one another. With nonresponse and measurement error, the two sources seem more or less uncorrelated, with one exception—those most prone to social desirability bias (those in the undesirable categories) are also less likely to respond. In addition, the propensity for unit nonresponse seems to be related to item nonresponse.
