Berdasarkan pengamatan penulis dalam proses pembelajaran meja Belajar dimana siswa kurang baik kemampuan backhand. Ini terbukti dari backhand siswa yang belum maksimal dalam kembalinya bola, dan dalam melakukan backhand smash. Diduga jumlah faktor yang rendah seperti kondisi fisik: Fleksibilitas pergelangan tangan, kekuatan otot lengan bahu, daya tahan otot, keseimbangan, fleksibilitas punggung, kecepatan reaksi. Instrumen penelitian adalah uji kelenturan tes pergelangan tangan dan backhand, teknik pengambilan sampel porpusive penelitian ini menggunakan random sampling dengan sampel 14 siswa Prodi penjaskerek putra. Penelitian ini merupakan jenis penelitian korelasi. Kemudian, analisis data menggunakan rumus korelasi Product Moment Correlation. Berdasarkan hasil penelitian dan pengolahan data menggunakan prosedur statistik, penelitian menyimpulkan bahwa ada trade-off antara kelenturan pergelangan tangan dengan kemampuan backhand di mana rhitungnya -0058.

While price and data quality should define the major trade-off for consumers in data markets, prices are usually prescribed by vendorsand data quality is not negotiable. In this paper we study a modelwhere data quality can be traded for a discount. We focus on the case ofXML documents and consider completeness as the quality dimension. Inour setting, the data provider offers an XML document, and sets boththe price of the document and a weight to each node of the document,depending on its potential worth. The data consumer proposes a price.If the proposed price is lower than that of the entire document, thenthe data consumer receives a sample, i.e., a random rooted subtree ofthe document whose selection depends on the discounted price and theweight of nodes. By requesting several samples, the data consumer caniteratively explore the data in the document. We show that the uniformrandom sampling of a rooted subtree with prescribed weight isunfortunately intractable. However, we are able to identify several practical casesthat are tractable. The first case is uniform random sampling of a rootedsubtree with prescribed size; the second case restricts to binary weights.For both these practical cases we present polynomial-time algorithmsand explain how they can be integrated into an iterative exploratorysampling approach.

The Relationship

The study identified the financial performance of Small and Medium Enterprises (SMEs) in Kota Bharu, Kelantan, specifically during the coronavirus disease (COVID-19) outbreak. Financial performance is a new but popular topic in this globalisation era, particularly during the pandemic. The study examined four factors: technology cost, bank credit, employee cost, and economic, focusing on SMEs in Kota Bharu, Kelantan. The main objective is to identify vital factors affecting SMEs’ financial performance in Kota Bharu, Kelantan and the relationship between technology cost, bank credit, employee cost, and economic towards the financial performance. Significantly, the study benefits SME entrepreneurs and upcoming entrepreneurs to identify the factors affecting the financial performance of SMEs. The Trade-Off Theory (TOT) was used to explain the study model. Besides, simple random sampling was used with 66 valid responses from SMEs in Kota Bharu, Kelantan tested and analysed using Google Form questionnaires.

Specific Orientation

Investigations which require electron microscope examination of a few specific areas of non-homogeneous tissues make random sampling of small blocks an inefficient and unrewarding procedure. Therefore, several investigators have devised methods which allow obtaining sample blocks for electron microscopy from region of tissue previously identified by light microscopy of present here techniques which make possible: 1) sampling tissue for electron microscopy from selected areas previously identified by light microscopy of relatively large pieces of tissue; 2) dehydration and embedding large numbers of individually identified blocks while keeping each one separate; 3) a new method of maintaining specific orientation of blocks during embedding; 4) special light microscopic staining or fluorescent procedures and electron microscopy on immediately adjacent small areas of tissue.

Speed And Accuracy

In most work contexts, several performance goals coexist, and conflicts between them and trade-offs can occur. Our paper is the first to contrast a dual goal for speed and accuracy with a single goal for speed on the same task. The Sternberg paradigm (Experiment 1, n = 57) and the d2 test (Experiment 2, n = 19) were used as performance tasks. Speed measures and errors revealed in both experiments that dual as well as single goals increase performance by enhancing memory scanning. However, the single speed goal triggered a speed-accuracy trade-off, favoring speed over accuracy, whereas this was not the case with the dual goal. In difficult trials, dual goals slowed down scanning processes again so that errors could be prevented. This new finding is particularly relevant for security domains, where both aspects have to be managed simultaneously.
