Stepwise Regression

Inseminasi buatan dikenal oleh peternak sebagai teknologi reproduksi ternak yang efektif. Penelitian ini bertujuan mengetahui faktor-faktor yang memengaruhi keberhasilan inseminasi buatan pada sapi di Kabupaten Asahan yang dipelihara secara intensif. Metode penelitian ini adalah metode survey, menggunakan data primer dan data sekunder. Data primer diperoleh dengan cara membagikan kuesioner dan wawancara langsung ke peternak sebagai tambahan informasi, sedangkan data sekunder didapat dari inseminator terkait tentang hasil inseminasi buatan di Kabupaten Asahan. Kuesioner yang digunakan mencakup pertanyaan tentang karakteristik sapi seperti: status kebuntingan sapi (konfirmasi dari petugas inseminator), jenis sapi, umur sapi, skor kondisi tubuh sapi, jumlah inseminasi buatan sampai bunting, tanda-tanda berahi, waktu pelaksanaan inseminasi buatan, bulan pelaksanaan inseminasi buatan, lama birahi pascapartus, jenis straw, jumlah dosis inseminasi, jarak waktu pelaporan berahi sampai dengan IB dilaksanakan, pakan sapi, ternak dikandangkan serta profil peternak dengan 75 responden peternak dari lima kecamatan. Data dianalisis menggunakan stepwise regression. Hasil penelitian menunjukkan bahwa dari 114 ekor ternak sapi betina yang dilakukan IB, sebanyak 76,3% mengalami kebuntingan dan 23,7% tidak mengalami kebuntingan. Variabel independen yang mempunyai korelasi paling kuat adalah umur sapi (sig. 0,006), jarak waktu pelaporan sampai IB (sig. 0,001), serta pakan ternak sapi (sig. 0,004). Kesimpulan penelitian bahwa faktor-faktor yang memengaruhi keberhasilan inseminasi buatan pada sapi di Kabupaten Asahan adalah umur sapi, jarak waktu pelaporan sampai inseminasi buatan dilaksanakan, dan pakan. Kata kunci: Faktor keberhasilan, Inseminasi buatan, Jenis pakan, Umur sapi

Single Marker

Studies examining associations between self-reported dairy intake and health are inconclusive, but biomarkers hold promise for elucidating such relationships by offering objective measures of dietary intake. Previous human intervention studies identified several biomarkers for dairy foods in blood and urine using non-targeted metabolomics. We evaluated the robustness of these biomarkers in a free-living cohort in the Netherlands using both single- and multi-marker approaches. Plasma and urine from 246 participants (54 ± 13 years) who completed a food frequency questionnaire were analyzed using liquid and gas chromatography-mass spectrometry. The targeted metabolite panel included 37 previously-identified candidate biomarkers of milk, cheese, and/or yoghurt consumption. Associations between biomarkers and energy-adjusted dairy food intakes were assessed by a ‘single-marker’ generalized linear model, and stepwise regression was used to select the best ‘multi-marker’ panel. Multi-marker models that also accounted for common covariates better captured the subtle differences for milk (urinary galactose, galactitol; sex, body mass index, age) and cheese (plasma pentadecanoic acid, isoleucine, glutamic acid) over single-marker models. No significant associations were observed for yogurt. Further examination of other facets of validity of these biomarkers may improve estimates of dairy food intake in conjunction with self-reported methods, and help reach a clearer consensus on their health impacts.

Heart failure is one of the leading causes of mortality worldwide. Several predictive risk scores and factors associated with in-hospital mortality have been reported for acute heart failure. However, only a few studies have examined the predictors in elderly patients. This study investigated determinants of in-hospital mortality in elderly patients with acute heart failure, aged 80 years or above, by evaluating the serum sodium, blood urea nitrogen, age and serum albumin, systolic blood pressure and natriuretic peptide levels (SOB-ASAP) score. We reviewed the medical records of 106 consecutive patients retrospectively and classified them into the survivor group (n = 83) and the non-survivor group (n = 23) based on the in-hospital mortality. Patient characteristics at admission and during hospitalization were compared between the two groups. Multivariate stepwise regression analysis was used to evaluate the in-hospital mortality. The SOB-ASAP score was significantly better in the survivor group than in the non-survivor group. Multivariate stepwise regression analysis revealed that a poor SOB-ASAP score, oral phosphodiesterase 3 inhibitor use, and requirement of early intravenous antibiotic administration were associated with in-hospital mortality in very elderly patients with acute heart failure. Severe clinical status might predict outcomes in very elderly patients.

Predictive Role

The main research objective of this study was seeking the predictive role of closeness to parents, attachment, identity style, identity commitment, type of relationship, and having children in intimacy among young women and men. Many studies indicate differences in the level of engagement, communication, and satisfaction in relationships. The study group comprised 227 people, including 114 women (M = 29.99; SD = 4.36), and 113 men (M = 30.00; SD = 4.33). A total of 40% of the subjects were married, and the remaining 60% subjects were in informal relationships; 101 people had children and the other individuals were childless. The following instruments were used: The Miller Social Intimacy Scale, questionnaires to assess closeness and attachment, and the Identity Style Inventory. The significance of the differences and the stepwise regression analysis were performed. The results of the study demonstrated a higher level of intimacy in a relationship with a partner among women than men. The nature of a relationship does not matter to the sense of intimacy. However, closeness to parents during childhood and adolescence, the model of interpersonal relations, and the identity style are predictors of intimacy in a relationship. The study results can be used in creating preventive and educational programs focused on family life and satisfied relationships.

Long Term Trends

Ecosystem services management should often expect to deal with non-linearities due to trade-offs and synergies between ecosystem services (ES). Therefore, it is important to analyze long-term trends in ES development and utilization to understand their responses to climate change and intensification of human activities. In this paper, the region of Uxin in Inner Mongolia, China, was chosen as a case study area to describe the spatial distribution and trends of 5 ES indicators. Changes in relationships between ES and driving forces of dynamics of ES relationships were analyzed for the period 1979–2016 using a stepwise regression. We found that: the magnitude and directions in ES relationships changed during this extended period; those changes are influenced by climate factors, land use change, technological progress, and population growth.

Statistical Results

The research presented in this paper is aimed at defining a model that enables the management of the relationship between private vehicles and public transport applying the available instruments of city transport policy such as parking policy and public transport policy measures. Statistical data used for modelling is sourced from the database in a wide range of EU cities. The target model was developed in the form of stepwise regression analysis. Very favourable statistical results were obtained, and the subsequent tests on the city of Novi Sad (250000 inhabitants) led to the conclusion that the obtained results were suitable for implementation in practice. The results of the implemented procedure are of great importance for the enhancement of the existing transport policies in cities, as they enable the development of strategies for finding combinations of instruments that would bring the transport system and urban environment into a desired-viable rather than consequential condition.

Psychiatric Intervention

A sample of 504 elderly persons living within a metropolitan area were questioned about their socio-medical characteristics and administered the Wakefield Self-assessment Depression Inventory. The distribution of depression scores indicated that 34.5% were depressed. Stepwise regression analysis was next used to examine the relationships between the characteristics and depression scores. Total number of self-reported symptoms and being partially housebound were positively associated with depression. Recommendations were made that health care providers for the elderly be alerted that older persons with physical complaints and those who are partially restricted to their homes may tend to develop levels of depression which might require psychiatric intervention.
