This is a report on the utility of a scale measuring attitudes toward illegal immigrants in two samples from nations that have more people moving out of the country than moving into the country. The Attitude toward Illegal Immigrants Scale was administered to 219 undergraduates from Sofia University in Bulgaria, and 179 undergraduates from Hanoi State University in Vietnam. Results yielded a scale with no sex differences, and acceptable alpha coefficients. Item analysis identified the most contributory and least contributory items, with considerable overlap in the two samples. A principal component analysis with varimax rotation was carried out to examine the structure.

In diesem Beitrag wird die Überprüfung des Assessment-Instruments zur Einschätzung der Wirksamkeit familiärer Strategien (ASF-E) für die Anwendung in Deutschland und der deutschsprachigen Schweiz beschrieben. Das ASF-E ist ein Screening-Instrument für Familiengesundheit, wie sie in der Theorie des systemischen Gleichgewichts definiert ist (Friedemann, 1991). Zunächst wurde das Instrument in den frühen 1990er Jahren in der Schweiz unter Berücksichtigung kultureller Unterschiede ins Deutsche übersetzt. Die vorliegende Testung war die erste in Deutschland und die zweite in der Schweiz. Das Instrument hatte ursprünglich 26 Items, wobei jedes drei Aussagen beinhaltet, die Familienstrategien ausdrücken und von denen die Probanden dasjenige auswählen sollten, das am ehesten auf ihre Familiensituation zutrifft. Die Aussagen sind von 1 bis 3 gestaffelt, wobei der Wert 3 für optimale, zufrieden stellende Gesundheit steht. In Deutschland wurde das Instrument von 343 und in der Schweiz von 209 Befragten aus der Gemeinde ausgefüllt, die sowohl unterschiedlichen Alters als auch unterschiedlicher ökonomischer Herkunft waren. Eine Principal Component Analysis mit Varimax Rotation brachte vier Faktoren mit einem Eigenwert > 1 hervor. Acht Items mussten herausgenommen werden, da sie eine unzureichende Verteilung oder zu schwache Faktorladungen aufwiesen. Das endgültige Assessment-Instrument hat 18 Items mit einem akzeptablen Wert für Reliabilität (Cronbach Alpha). Das ASF-E kann in Deutschland und in der Schweiz genutzt werden, um Forschung mit Familien zu begleiten und Familiengesundheit in Verbindung mit Pflegeinterventionen einzuschätzen.

IntroductionThe FMPS is a 35-item self-report questionnaire to measure perfectionism. It evaluates: concern over mistakes/CM, doubts about actions/DA, parental criticism/PC and expectations/PE, personal standards/PS and organization/O.ObjectivesTo develop a shortened version of FMPS and study its internal consistency, the construct, concurrent and divergent validity.MethodsOne hundred and ninety-two university students (78.1% females), aged 19.74 years (sd = 2.10) completed the Portuguese versions of the: FMPS, Hewitt and Flett MPS/H&FMPS, Life Orientation Test Revised/LOT-R, State-Trait Anxiety Inventory/STAI, and Profile of Mood States/POMS.ResultsCorrelations between each item and corrected FMPS total scores/corrected total subscales scores were ≥ 0.20 for the items 13, 15, 25, 31, 35 and 10, 2, 25, and 26, respectively. The internal consistency of FMPS was high (α: .857) with 32 items contributing for this consistency (exceptions: 13, 25 and 31). The principal component analysis of the 35 items with factors varimax rotation was performed. The three items with higher loading in each factor that also contributed to the FMPS reliability were selected for the FMPS shortened version (FMPS-18). The principal component analysis of the 18 items with factors varimax rotation showed that six factors explained 74.6% of FMPS-18 total variance. These factors revealed adequate internal consistency (α: O = 0.740; PC = 0.859; PE = 0.847; PS = 0.726; CM = 0.740; DA = 0.832; total = 0.768). Convergent correlations between FMPS and the matched FMPS-18 scores were 0.839 to 0.971 (all P < .01). Correlations of the FMPS-18 and FMPS with H&F-MPS, STAI, LOT-R and NA/PA scores were of similar significance and valence.ConclusionFMPS-18 is a brief, reliable and valid instrument to measure perfectionism.Disclosure of interestThe authors have not supplied their declaration of competing interest.

This paper examined the effects of brewery wastewater on the quality of water in Ikpoba River which has experienced significant pollution over the years, with the intention of determining the main pollutant in the river water. Samples were recovered from eight (8) different locations covering a total distance of 750 m: one sample from upstream at 150 m from the effluent discharge location, two samples from effluents discharge point and five samples from downstream location at 150 m interval. Samples were taken twice monthly in March, May and July, 2014 during period of intense activity of production. The physcio-chemical analyses of the twenty-five (25) selected parameters were calculated and values obtained were used to calculate the water Quality index of the river. The results indicated that Ikpoba River is severely polluted (WQI = -5429792.89, in SN1, March, 2014) as a result of untreated brewery effluent hence Principal Component Analysis (PCA) was applied to determine the parameter that contributes mainly to the pollution and those that contributed minimally. Evaluation of the PCA results shows that the only reoccurring parameter is Copper hence it is concluded that Copper is the only component factor that influences the river water quality throughout the period under study. Therefore, it is strongly recommended that any proposed treatment method must be targeted at the removal of copper in addition to other factors of high contributory effects.

Functional Principal Component Analysis (FPCA) is an important dimension reduction technique to interpret the main modes of functional data variation in terms of a small set of uncorrelated variables. The principal components can not always be simply interpreted and rotation is one of the main solutions to improve the interpretation. In this paper, two new functional Varimax rotation approaches are introduced. They are based on the equivalence between FPCA of basis expansion of the sample curves and Principal Component Analysis (PCA) of a transformation of the matrix of basis coefficients. The first approach consists of a rotation of the eigenvectors that preserves the orthogonality between the eigenfunctions but the rotated principal component scores are not uncorrelated. The second approach is based on rotation of the loadings of the standardized principal component scores that provides uncorrelated rotated scores but non-orthogonal eigenfunctions. A simulation study and an application with data from the curves of infections by COVID-19 pandemic in Spain are developed to study the performance of these methods by comparing the results with other existing approaches.

Background: Accurate and reliable self-report measurement tools examining depressive symptoms are scant in child psychiatry. This study assessed the psychometric properties of the Chinese Version of the Quick Inventory of Depressive Symptomatology-Self-Report (C-QIDS-SR) in depressed adolescents in China.Methods: Adolescents with major depressive episodes or bipolar depressive episodes were assessed using the C-QIDS-SR. The structure validity of the C-QIDS-SR was estimated using principal component analysis with varimax rotation.Results: A total of 246 depressed adolescents were included in the study. Cronbach's alpha was 0.77. The correlation coefficient between the baseline and endpoint assessments was 0.49 (p &lt; 0.001), whereas, the correlation coefficient between the C-QIDS-SR and the Hamilton Rating Scale for Depression−17 items (HAMD-17) was 0.63 (p &lt; 0.001). Principal component analysis with varimax rotation demonstrated the unidimensional structure of the C-QIDS-SR.Conclusion: The C-QIDS-SR is a reliable and valid instrument with acceptable psychometric properties to measure depressive symptoms in adolescents.

Six variables associated with periodontal disease were evaluated in 635 men. Correlations between individual variables were low to moderate.' Highest correlations were observed between bone loss and tooth mobility. Principal component analysis of the intercorrelation matrix, followed by Varimax rotation of the factor matrix, demonstrated two distinct factors, periodontitis and gingivitis.

<p>Jeruk siam Gunung Omeh/Gn. Omeh (Citrus nobilis Lour.) merupakan jeruk lokal yang berkembang di seluruh sentra jeruk Sumatera Barat. Namun, buah yang ada di pasar sangat beragam fenotipiknya. Tujuan penelitian adalah untuk mengelompokkan sebaran tanaman jeruk Gn. Omeh yang berada pada empat Kabupaten berdasarkan karakter genetik dan morfologi. Penelitian dilakukan pada bulan Januari sampai dengan Juni 2016, dengan 21 contoh daun dan buah berasal dari petani di empat kabupaten pengembangan wilayah jeruk Sumatera Barat (Kabupaten Limapuluh Kota, Agam, Solok Selatan, dan Tanah Datar), dan dua contoh daun kontrol masing-masing asal BPMT dan PIT di Kabupaten Limapuluh Kota. Keragaman morfologi daun dan buah dianalisis dengan Analisis Komponen Utama (Principal Component Analysis/PCA). Data yang dihasilkan dianalisis lebih lanjut dengan kluster analisis untuk mengamati pengelompokannya. Hasil penelitian menunjukkan tingkat kemiripan secara genetik 23 contoh jeruk Gn. Omeh yang dianalisis menggunakan dua macam RAPD marker, yaitu OPA 04 dan OPA 18 yang menghasilkan 24 pita, di mana 83,3% adalah polimorfik. Berdasarkan dendrogram yang dihitung menurut UPGMA, 23 contoh daun jeruk secara genetis terbagi menjadi dua kelompok besar. Pada kelompok I, terdapat dua contoh asal Kabupaten Limapuluh Kota, sedangkan 21 contoh sisanya berada pada kelompok II. Pada derajat kemiripan antara 86,5–96%, tanaman PIT mirip dengan A1 dan satu subkelompok dengan S2, A5, T3, T5, dan S1, sedangkan BPMT mirip dengan T4, dan satu subkelompok dengan A4 dan A3. Berdasarkan karakter morfologi pada derajat kemiripan 75%, jeruk Gn. Omeh di Sumatera Barat terbagi menjadi lima kelompok, di mana pada kelompok 1, 3, 4, dan 5 masing-masing adalah contoh L1, T5, S5, dan S2, sedangkan 18 tanaman lainnya masuk di dalam kelompok 2. Dari hasil analisis secara genetik maupun morfologi menghasilkan derajat variasi yang cukup tinggi di antara 23 contoh yang ada. Hal ini menunjukkan bahwa keragaman buah yang ada diduga disebabkan oleh penggunaan benih serta pengelolaan tanaman yang beragam.</p><p>The Gunung Omeh citrus (Citrus nobilis Lour.) is a local citrus growing throughout the citrus center of West Sumatera. However, the fruits available in the market are very diverse phenotypic. The purpose of this study is to classify the spread of citrus cv. Gn. Omeh derived from four districts based on genetic and morphological characters. The study was conducted from January to June 2016, with 21 of leaf and fruit samples collected from four Citrus District Regional Development farmers in the West Sumatera (Limapuluh Kota, Agam, Solok Selatan, and Tanah Datar). Besides that, control leaf samples derived from Budwood Multiplication Block/BPMT and Single Mother Tree/PIT were used. The morphological diversity both leaves and fruits were analyzed by Principal Component Analysis (PCA). The result showed that the level of genetic similarity in 23 samples of orange Gn. Omeh analyzed using two markers RAPD namely OPA 04 and OPA 018 which generate 24 bands, where 83.3% were polymorphic The resulting data were further analyzed by cluster analysis to observe groupings. Based on the dendrogram calculated according to UPGMA, 23 samples genetically are divided into two major groups. In the first group, there are two samples from Limapuluh Kota, while the remaining 21 samples are in second group. On the degree of similarity between 86.5–96%, PIT similar to the A1 plant and it belong to the same subgroup with S2, A5, T3, T5, S1. While BPMT similar to T4 plant, and it belong to the same subgroup with A4 and A3. Based on morphological characters at a 75% degree of similarity, the Gn. Omeh citrus in West Sumatra is divided into five groups, where the L1, T5, S5, and S2 plant sample belongs to the groups 1, 3, 4, and 5, respectively, while 18 others in Group 2. From the analysis of both genetic and morphological characters, it generates fairly high degree of variation among 23 samples. This shows that the diversity of the marketed is thought to be caused by the use of seed plants and crop cultivated management are diverse.</p>
