This study aims to determine the development of sportsmanship in children through a modified game of HOT (Hoki Tiup) during the pandemic. The research was conducted at Rumah Belajar All Kids. The research subjects were selected by purposive sampling, namely 4 children aged 5-6 years who did limited face-to-face learning. This research is a qualitative research with a case study approach. Methods of data collection used interviews, observation, and document study. The data analysis was used the data reduction stage, data presentation and conclusion drawing. The results of this study indicate that sportsmanship develops from the aspects of respect, fairness, and acceptance of the results of the game. Respect is shown through natural expressions when experiencing victory or defeat. A fair attitude is marked by the child starting to obey the rules of the game when playing with all his friends.The child receives the final result of the game.

Distant Supervision is an approach that allows automatic labeling of instances. This approach has been used in Relation Extraction. Still, the main challenge of this task is handling instances with noisy labels (e.g., when two entities in a sentence are automatically labeled with an invalid relation). The approaches reported in the literature addressed this problem by employing noise-tolerant classifiers. However, if a noise reduction stage is introduced before the classification step, this increases the macro precision values. This paper proposes an Adversarial Autoencoders-based approach for obtaining a new representation that allows noise reduction in Distant Supervision. The representation obtained using Adversarial Autoencoders minimize the intra-cluster distance concerning pre-trained embeddings and classic Autoencoders. Experiments demonstrated that in the noise-reduced datasets, the macro precision values obtained over the original dataset are similar using fewer instances considering the same classifier. For example, in one of the noise-reduced datasets, the macro precision was improved approximately 2.32% using 77% of the original instances. This suggests the validity of using Adversarial Autoencoders to obtain well-suited representations for noise reduction. Also, the proposed approach maintains the macro precision values concerning the original dataset and reduces the total instances needed for classification.

PurposeThis study examines the relative efficiencies of anti-poverty policies implemented in 28 Chinese provinces.Design/methodology/approachThis study uses meta-frontier undesirable dynamic two-stage data envelopment analysis. The authors divide the poverty reduction process into two stages: agricultural production and poverty reduction. Public expenditure is the input for the second stage, and the population below the poverty line is the undesirable output. The authors compute the efficiencies (overall efficiency, efficiency of each stage and the efficiencies of individual inputs and outputs) using meta-frontier analysis for the 28 provinces.FindingsThe results show that: (1) a significant imbalance exists between the eastern and western regions in terms of input-output efficiencies; (2) the poverty reduction stage generally fared better than the agricultural production stage did. In particular, most provinces saw increases in poverty reduction efficiencies between 2013 and 2017; (3) the place-based poverty relief policies introduced in recent years are effective at reducing the poverty rate and reaching the government-set goals and (4) while disposable income has increased steadily over the past few years, income inequality has been exacerbated.Research limitations/implicationsThe results show that: (1) a significant imbalance exists between the eastern and western regions in terms of input-output efficiencies; (2) the poverty reduction stage generally fared better than the agricultural production stage did. In particular, most provinces saw increases in poverty reduction efficiencies between 2013 and 2017; (3) the place-based poverty relief policies introduced in recent years are effective at reducing the poverty rate and reaching the government-set goals and (4) while disposable income has increased steadily over the past few years, income inequality has exacerbated.Originality/valueA large amount of attention and public resources are devoted to fighting poverty and associated market failures in China. The extant literature focuses either on the agricultural production itself or the relationship between human capital and productivity levels. Making use of recent developments of the DEA method, the authors propose a new framework for evaluating the efficiencies of the poverty reduction process. Such a framework has the advantage of giving researchers and policymakers a more detailed diagnosis with regard to the components in the endeavor to eliminate poverty and providing useful information for policymakers to optimize public funds use. Methodologically, the framework is flexible enough to be employed for future research in similar appraisals, at different geographic and scale aggregation levels, for public projects including but not limited to poverty reduction.

This study aims to describe the ability of teachers in preparing the 2013 curriculum learning plans in elementary schools. This type of research is descriptive qualitative research with the research subject of class teachers and school principals. Data collection techniques in the form of observation, interviews and document review. The data analysis technique uses the Milles and Huberman model which consists of three stages, namely the data reduction stage, the data presentation stage and the conclusion drawing stage. The results showed that the teacher had prepared a 2013 curriculum lesson plan by developing a syllabus and lesson plans. In addition, the teacher periodically also makes revisions to the lesson plans that have been made, only the fact that in the preparation of learning plans sometimes teachers do not go through the stages as directed in the 2013 curriculum. Needs to be done an evaluation so that the quality of the lesson plans that teachers produce can be even better.

Abstract The objective of this paper is to experimentally and numerically investigate the transient cavitation flow during the startup process of mixed flow pump with emphasis on studying the influence of blade numbers. The transient cavitation simulation was studied based on the improved SST k-ω turbulence model and the Zwart cavitation model. Firstly, in order to obtain the relationship between transient flow rate and the variation of rotational speed at startup, a theoretical analysis based on the fast transients of centrifugal pump was first applied to mixed flow pump and was verified by the current experiment study. Subsequently, the influence of blade number on the cavitation flow in the startup was studied. It is found that the transient cavitation could be classified into four stages regardless of the number of blades: no cavitation stage, the cavitation growth stage, the cavitation reduction stage and the cavitation stabilization stage. However, the blade number does have an impact on the spatial-temporal evolution of cavitation. More specifically, when the blade number increases, the initial cavitation appeared lately, the coverage area of the triangular cavitation cloud and sheet cavitation both decreased, and the increase in blade number has a better inhibitory effect on the sheet cavitation at the cavitation growth stage, and can make sheet cavitation disappear more quickly at the cavitation reduction stage.

The processing of Cu, Co, and Zn at the Boleo project in Mexico involves two-stage (oxidation–reduction) leaching to extract a total of 85–88% Cu in 4 h. The first stage is an oxidation leaching using sulphuric acid (120 kg/tonne ore) at an Eh of 900 mV for 2 h. Then, the reduction stage takes place in 2 h with SO2 gas sparging for Mn and Co extraction at an Eh of 350–370 mV. The final extraction rates of metal values are 92% of Mn, 80% of Co, and 60% of Co, respectively, after 4 h of leaching at 70 °C. However, the same metal recoveries were obtained within 2 h using an equal amount of sulphuric acid and the addition of 25 kg of SO2 per tonne of ore in a single stage leaching in this research. In this case, the Fe extracted from the ore as Fe2+/Fe3+ is believed to have acted as an electrochemical couple contiguously leaching the Cu sulphide and Mn oxides, which also increased the Cu recovery as the Cu mineralised mostly intergrowths in these mineral structure matrices. A significant improvement was made in which the leaching time was halved to 2 h compared to 4 h in the previous plant design and current operation, involving the two-stage oxidation–reduction leaching.

This study aims to: 1) find out the opportunities for Bontolebang fishermen's households to survive, 2) find out the strategies of fishermen households to survive through job diversification. This type of research is ethnographic qualitative. Data was collected by observation, interviews, and documentation. The data analysis used is qualitative data analysis through the reduction stage, data presentation and conclusion drawing. The results showed that the strategy adopted was an adaptation strategy, and a job diversification strategy by empowering fisherwomen and women-headed households (WKRT) of fishermen, both related to fishing and outside activities. Job diversification opportunities have a dependence on nature that provides resources, so that resource potential is optimized in job diversification alternatives. The diversity of characteristics of the natural environment that each fisherman has. Fishing for fishermen's households is a speculative activity, therefore, fishermen always have an uncertain income. Women become an important part in fulfilling the needs of household life because of the system based on the division of labor. The research implication is that the government, stakeholders and other communities can work together with each other to build policies, or go directly to build fishing villages that are low-income

Approximate computing is an attractive technique to gain substantial improvement in the area, speed, and power in applications where exact computation is not required. This paper proposes two improved multiplier designs based on a new 4:2 approximate compressor circuit to simplify the hardware at the partial product reduction stage. The proposed multiplier designs are targeted towards error-tolerant applications. Exhaustive error and hardware analysis has been carried out on the existing and proposed multiplier designs. The results prove that the proposed approximate multiplier architecture performs better than the existing architectures without significant compromise on quality metrics. Experimental results show that die-area and power consumed are reduced upto 28%, and 25.29% respectively in comparison with the existing designs without significant compromise on accuracy.
