Canonical Correspondence Analysis

Tindak kriminal merupakan segala macam bentuk tindakan yang merugikan secara ekonomis dan psikologis yang melanggar hukum, norma-norma sosial, serta agama. Terjadinya tindak kriminal di suatu wilayah dapat berhubungan dengan berbagai karakter masyarakat diantaranya pendidikan, kependudukan, dan ekonomi. Setiap wilayah di Indonesia pasti memiliki karakteristik yang berbeda-beda, sehingga kecenderungan terjadinya tidak kriminal akan berbeda pula di setiap wilayahnya. Penelitian ini dilakukan dengan tujuan untuk membuat pemetaan jenis tindak kriminal berdasarkan karakteristik wilayah di Indonesia. Unit pengamatan pada penelitian ini adalah 34 provinsi di Indonesia. Data yang digunakan adalah data sekunder yang didapat dari Badan Pusat Statistik Indonesia pada tahun 2019. Metode yang digunakan pada penelitian adalah metode Canonical Correspondence Analsis (CCA). Hasil penelitian didapatkan pemetaan jenis-jenis tindak kriminal berdasarkan karakteristik wilayah di Indonesia pada peta triplot. Peta tripot yang dihasilkan dapat menjelaskan 90.6% dari total inersia yang ditangkap oleh CCA. Melalui uji permutasi Monte Carlo, ditunjukkan bahwa terdapat hubungan yang signifikan antara karakteristik wilayah dengan penyebaran jenis tindak kriminal.

Foi realizado um inventário florístico-estrutural da regeneração natural de espécies arbustivo-arbóreas do sub-bosque de um plantio homogêneo de Mimosa scabrella Bentham implantado, visando à reabilitação de área minerada, em Poços de Caldas. Foram utilizadas dezenove parcelas de 50 m2 (5 m × 10 m) e amostrados os indivíduos arbustivo-arbóreos com altura igual ou superior a 30cm, tendo sido encontrados 1.946 indivíduos, pertencentes a 63 famílias botânicas. Amostras de solo foram coletadas à profundidade de 0 cm a 20 cm, em cada uma das dezenove parcelas e analisados os teores de areia, silte, argila, matéria orgânica, pH, nitrogênio, fósforo, potássio, cálcio e magnésio. Foi analisada a influência de variáveis edáficas sobre a densidade das espécies amostradas, utilizando Análise de Correspondência Canônica ("Canonical Correspondence Analysis" - CCA). Foi verificada correlação significativa entre elas a 5% de probabilidade pelo teste de Monte-Carlo. As espécies Miconia sellowiana, Miconia pepericarpa, Cestrum amictum, Alchornea triplinervia, Cordia superba e Casearia sylvestris apresentaram comportamento próximo ao indiferente em relação às variáveis edáficas estudadas, sendo que estas se destacam de forma superior em relação às demais espécies quanto aos parâmetros florístico-estruturais. Esse comportamento reforça a indicação de tais espécies, feita por NAPPO (1999), como de potencial para uso em plantios mistos e de enriquecimento em condições similares às da área estudada. A identificação e mensuração de outras variáveis ambientais e do histórico da área são peças importantes para o entendimento dos processos de dinâmica de povoamentos e, em particular, para áreas degradadas em fase de reabilitação.

The relationship between the weed communities and environmental variables such as soil, crop, and management was investigated in two provinces of Canada. The frequencies of weed species were recorded in cereal and oilseed fields in Saskatchewan (2244 fields over 4 years) and Manitoba (864 fields over 3 years), Canada. Information on some of the physical characteristics of the fields and on the management practices imposed on them was also collected, in part by questionnaire. The two kinds of data were ordinated together using canonical correspondence analysis to assess the relationships between the species and the environmental variables. In the Saskatchewan data, there was a clear and consistent separation of the species into groups along an axis correlated with soil zone and the associated climatic gradient. In the Manitoba data, the same groups of species did not separate as clearly or as consistently, although geographic region was a major determinant of the weed communities. The greater variability may be due to the fact that the gradient of soil types is much more restricted in Manitoba and not as closely correlated with climatic conditions. In both provinces, culture practices were less important as correlates of the weed community composition than soil type or, to a certain extent, the previous crop. Key words: canonical correspondence analysis, cereal crops, oil seed crops.

Species composition of desmid algae and their habitat preferences in water bodies of Ekaterinburg city were studied during the 2013–2017. Thirty-seven species and subspecific taxa which belong to 12 genera and 2 families were identified, of which 17 species are new for the eastern macroslope of the Middle Urals. Canonical correspondence analysis, which was performed to reveal habitat preferences, demonstrates that the majority of analyzed species prefer quarry lakes, ponds and overgrown lake shores, contrary to fens and rivers.

Election Results

Ordination techniques such as CCA (Canonical Correspondence Analysis) or RDA (Redundancy Analysis) are very popular in ecological research but almost completely unknown in, for example, socio-economic research. The goal of this paper is to concisely organize the concepts and terminology associated with ordination and to present the possibilities of its application in social research with an example of the analysis of the 2015 parliamentary elections results.
