"Evaluation of Sampling Methods for Scatterplots" claims that people perform dot-density comparisons best when using random sampling rather than other sampling approaches. This claim and other core conclusions of the article are not supported by the article’s empirical evidence. The article’s reported results and figures do not meet its own stated threshold of statistical significance, and the analyses are ill-suited for the research questions. Some of these issues are present in the article and could have been spotted by reviewers, whereas other issues were only noticeable because I requested the code and data after publication (which a reviewer would have been prohibited from demanding during the IEEE TVCG review process). A reanalysis calls into question whether any generalizable claims can be made from these results.

Legitimacy Crisis

This chapter presents the research questions and outline of the book, providing a brief review of the state of the art of legitimacy research in established democracies, and discusses the recurring theme of crisis throughout this literature since the 1960s. It includes a discussion of the conceptualization and measurement of legitimacy, seeking to relate legitimacy to political support, and reflecting on how to evaluate empirical indicators: what symptoms indicate crisis? This chapter further explains the structure of the three main parts of the book. Part I evaluates in a systematic fashion the empirical evidence for legitimacy decline in established democracies; Part II reappraises the validity of theories of legitimacy decline; and Part II investigates what (new) explanations can account for differences in legitimacy between established democracies. The chapter concludes with a short description of the chapters included in the volume.

Per Se

The first sport-science-oriented and comprehensive paper on magnitude-based inferences (MBI) was published 10 y ago in the first issue of this journal. While debate continues, MBI is today well established in sport science and in other fields, particularly clinical medicine, where practical/clinical significance often takes priority over statistical significance. In this commentary, some reasons why both academics and sport scientists should abandon null-hypothesis significance testing and embrace MBI are reviewed. Apparent limitations and future areas of research are also discussed. The following arguments are presented: P values and, in turn, study conclusions are sample-size dependent, irrespective of the size of the effect; significance does not inform on magnitude of effects, yet magnitude is what matters the most; MBI allows authors to be honest with their sample size and better acknowledge trivial effects; the examination of magnitudes per se helps provide better research questions; MBI can be applied to assess changes in individuals; MBI improves data visualization; and MBI is supported by spreadsheets freely available on the Internet. Finally, recommendations to define the smallest important effect and improve the presentation of standardized effects are presented.

Abstract After more than 80 years in predicting organizational performance, empirical evidence reveals a science of teams that seems unable to consistently implement solutions for teams performing in real work settings –outside and away from the isolated teams breeding in research laboratories in the academic context. To bridge this growing practitioners-researchers divide, we first identify five main challenges involved in working with teams today (purposeful team staffing; proper task design and allocation; task and interaction process functionality; appropriate affective tone; and suitable team assessment). And second, we offer a toolbox of interventions (empowering and restorative) to help practitioners to transform the potential threats inherent in these challenges into opportunities for team effectiveness. Our five-challenge diagnosis and proposed intervention toolbox contribute to better address research questions and theoretical falsifiability using teams performing in real work settings, and to assess and intervene in teams by adjusting their internal functioning to contextual conditions and constraints.

Applied Social Science

Significance testing is widely used in social science research. It has long been criticised on statistical grounds and problems in the research practice. This paper is an applied researchers’ response to Gorard's (2016) ‘Damaging real lives through obstinacy: re-emphasising why significance testing is wrong’ in Sociological Research Online 21(1). He participates in this debate concluding from the issues raised that the use and teaching of significance testing should cease immediately. In that, he goes beyond a mere ban of significance testing, but claims that researchers still doing this are being unethical. We argue that his attack on applied scientists is unlikely to improve social science research and we believe he does not sufficiently prove his claims. In particular we are concerned that with a narrow focus on statistical significance, Gorard misses alternative, if not more important, explanations for the often-lamented problems in social science research. Instead, we argue that it is important to take into account the full research process, not just the step of data analysis, to get a better idea of the best evidence regarding a hypothesis.

South Barito is an area of rattan and rattan production center of the province of Central Kalimantan, on the other hand is one area that has natural conditions very conducive to the development of rattan. This study reveals how patterns in addition to planting and processing of rattan traditionally also analyze the socio-economic level of society. Research conducted in South Barito regency, District Karau in Two Villages is Bangkuang and New Salat. The village of the second sample is determined gardens and population are farmers who cultivate cane with sampling methods by simple random sampling, because the peasant population is homogeneous, the number of samples in each village 34 respondents or 68 farmers overall. The result showed that in general the rattan garden where the studies were not well-maintained, where the average of respondents (45%) said that maintenance is only performed at the time of going to the harvesting or one for rattan planting. Besides the low price of rattan is led to a reduction of land management / rattan gardens intensively. and production of rattan average yield of 2.6 tons ha-1 or 245.5 clumps of cane ha-1. For the villagers of business administration studies despite conditions that are considered less favorable, but they still look forward to the Government's policy to remain aligned to the Farmers Rattan. In addition, because cane is inherited and used as a hallmark of South Barito society in general.Barito Selatan merupakan daerah penghasil rotan dan sentra produksi rotan provinsi Kalimantan Tengah, selain itu merupakan salah satu wilayah yang memiliki kondisi alam yang sangat mendukung bagi perkembangan rotan. Penelitian ini selain untuk mengungkapkan bagaimana pola tanam dan pengolahan rotan secara tradisional juga  menganalisis tingkat sosial ekonomi masyarakat. Penelitian dilaksanakan di Kabupaten Barito Selatan, Kecamatan Karau di Dua Desa yaitu Bangkuang dan Salat Baru. Dari kedua Desa tersebut ditentukan kebun sampel dan populasi masyarakat  yaitu  petani yang mengusahakan rotan dengan metode pengambilan sampel secara simple random sampling, karena populasi petani bersifat homogen, jumlah sampel di masing-masing desa 34 responden atau keseluruhan 68 petani. Dari hasil penelitian diperoleh bahwa pada umumnya kebun rotan di tempat penelitian tersebut tidak terpelihara dengan baik, dimana rata-rata responden (45%) menyebutkan bahwa pemeliharaan hanya dilakukan pada saat akan dilakukan pemanenan atau satu kali selama rotan itu di tanam. Selain itu rendahnya  harga  rotan  sangat  berdampak pada berkurangnya pengelolaan lahan/kebun rotan secara intensif. dan hasil produksi rotan rata-rata diperoleh 2,6 ton ha-1 atau 245,5 rumpun rotan ha-1. Bagi masyarakat Desa studi walaupun kondisi tataniaga yang dianggap kurang menguntungkan, namun mereka masih berharap kebijakan Pemerintah tetap berpihak kepada Petani Rotan. Di samping itu  karena pada umumnya rotan merupakan warisan dan digunakan sebagai ciri khas masyarakat Barito Selatan.

Peer review has become the gold standard in scientific publishing as a selection method and a refinement scheme for research reports. However, despite its pervasiveness and conferred importance, relatively little empirical research has been conducted to document its effectiveness. Further, there is evidence that factors other than a submission’s merits can substantially influence peer reviewers’ evaluations. We report the results of a metascientific field experiment on the effect of the originality of a study and the statistical significance of its primary outcome on reviewers’ evaluations. The general aim of this experiment, which was carried out in the peer-review process for a conference, was to demonstrate the feasibility and value of metascientific experiments on the peer-review process and thereby encourage research that will lead to understanding its mechanisms and determinants, effectively contextualizing it in psychological theories of various biases, and developing practical procedures to increase its utility.
