A new index to assess meteorological drought: the Drought Exceedance Probability Index (DEPI)
Full text linkThis paper presents a new index to determine meteorological drought conditions, the Drought Exceedance Probability Index (DEPI), derived from monthly precipitation time series. Its formulation is simple and undemanding in terms of baseline information requirements. This makes the DEPI suitable for routine application to any climate, similar to the well-known Standardized Precipitation Index (SPI). The index is based on the calculation of cumulative rainfall anomalies and their subsequent standardization, similarly to other indices. The hallmarks of the DEPI, and its main comparative advantages, are the process of accumulating anomalies and their standardization process. The paper compares the DEPI with the SPI in several different climates across the world and in all cases the results show the complementarity of both indices. The DEPI shows an excellent ability to reflect the actual severity and duration of droughts, without requiring application on different time scales, unlike the SPI. It is also valid for all types of climates, including arid and semiarid or Mediterranean, for which the literature has shown that using the SPI is problematic
Further investigation into the Rorschach and the utility of a modified DEPI in relation to adolescent depression
No full textThis study investigated the Rorschach and its ability to identify adolescent depression through the current DEPI and CDI, and through a proposed adolescent depression index using Rorschach variables. Past research (Ball et al., 1991; Ilonen et al., 1999; Viglione, 1999) has shown that the Rorschach is a poor predictor of adolescent depression. A sample of 200 non-depressed inpatient adolescents and 77 severely depressed inpatient adolescents made up the extreme groups. The groups were formed by utilizing multiple criteria that was part of a comprehensive battery, but did not include the Rorschach. The current DEPI and CDI were not found to be effective predictors of adolescent depression. In general, the proposed adolescent depression index was not found to be significantly better than the original DEPI. However, variables such as morbid with shading, human content \u3e 3, and AG + Fi + Bl \u3e 3 were significant and distinguished between the extreme groups
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
PERSEPSI MASYARAKAT KOTA PALOPO TERHADDAP KEBERADAAN USAHA DI LAPANGAN PANCASILA
Full text linkABSTRAK
Depi, 2021. “Persepsi Masyarakat Kota Palopo terhadap Keberadaan Usaha di
Lapangan Pancasila”.Skripsi Program Studi Ekonomi Syariah Fakultas
Ekonomi dan Bisnis Islam Institut Agama Islam Negeri Palopo.Dibimbing
oleh Fasihadan Yuyun Ruqiyyat Said.
Skripsi ini membahas tentang persepsi masyarakat Kota Palopo terhadap
keberadaan usaha di lapangan pancasila.Permasalahan utama dalam penelitian ini
adalah banyaknya pelaku usaha yang bongkar muat barang menimbulkan suara
bising, penempatan usaha yang memanfaatkan trotoar jalan, dan juga parkiran
kendaraan kurang memperhatikan lingkungan sekitar sehingga mengganggu
ketenangan warga setempat.Pelaku usaha di lapangan pancasila menimbulkan
berbagai persepsi mulai dari persepsi positif sampai dengan persepsi
negatif.Sebagian besar pelaku usaha yang terlibat di dalamnya adalah pemuda,
sehingga hal ini tentu memberikan dampak positif untuk masyarakat Kota Palopo
karena angka pengangguran yang menurun.Tujuan penelitian ini untuk
mengetahui bagaimana persepsi masyarakat Kota Palopo terhadap keberadaan
usaha di lapangan pancasila apakah masyarakat yang memberikan respon positif
terhadap keberadaan usaha di lapangan pancasila lebih besar dari pada masyarakat
yang memberikan respon negatif.Jenis penelitian ini adalah kualitatif, penelitian
ini dilaksanakan di lapangan pancasila Kelurahan Tompotikka Kecamatan Wara
Kota Palopo.Teknik pengumpulan data ada 3 yaitu observasi, wawancara, dan
dokumentasi.Selanjutnya data penelitian ini dianalisis untuk menarik kesimpulan.
Hasil penelitian ini menunjukkan bahwa meskipun terdapat bebarapa persepsi
negatif dari masyarakat sekitar terkait keberadaan pelaku usaha di lapangan
pancasilaakan tetapisebagian besar menimbulkan persepsi yang positif dari
masyarakat. Hadirnya lapangan pancasila sangat dimanfaatkan oleh masyarakat
khususnya pemuda untuk mengembangkan potensinya dalam menjalankan usaha,
serta menjadikan masyarakat Kota Palopo menjadi lebih produktif. Dari ketiga
persepsi diatas dapat ditarik kesimpulan bahwa meskipun terdapat bebarapa
persepsi negatif dari masyarakat sekitar terkait keberadaan usaha di lapangan
pancasilaakan tetapisebagian besar masyarakat memberikan persepsi yang positif.
Hadirnya lapangan pancasila sangat dimanfaatkan oleh masyarakat khususnya
pemuda untuk mengembangkan potensinya dalam menjalankan usaha, serta
menjadikan masyarakat Kota Palopo menjadi lebih produktif.

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Spatiotemporal characterization of meteorological drought: a global approach using the Drought Exceedance Probability Index (DEPI)
Full text linkWe present a global spatiotemporal characterization of meteorological droughts using historical precipitation data through the Drought Exceedance Probability Index (DEPI). The relationship between meteorological drought characteristics and monthly precipitation is explored at a global level. This study contributes to our understanding of the drought features observed in different areas of the planet, which can help predict the behavior of future droughts. The DEPI was applied to the Climate Research Unit global gridded high-resolution rainfall data set covering the period 1901-2019. Monthly drought index series were examined to extract the number of droughts experienced in each pixel (0.50° × 0.50°) of the globe, as well as their durations, intensities and severities. Results show agreement with other global drought characterization efforts, revealing areas with a greater drought occurrence. This paper demonstrates that regions with less seasonality and less intra- and inter-annual rainfall variability report fewer drought episodes. Duration and severity of droughts are also related to these rainfall features. The last part of the study describes the temporal distribution of droughts throughout the world. We conclude that regions with many events show stable, even distributions over time, but many pixels in the intertropical regions, the Middle East and smaller patches in Mongolia, China, Siberia and Canada currently show higher-intensity and longer-duration drought events than at the beginning of the twentieth century, while the opposite occurs in parts of Scandinavia, Russia, Argentina and Tanzania. The analysis demonstrates that DEPI is easy to use, is applicable to different climates and is effective in detecting the onset, end and intensity of droughts.</jats:p
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
