This paper summarizes the results of a number of Queensland studies of selection of students for admission to tertiary institutions. Data presented allow a comparison of external public examinations, school assessments moderated through a process of teacher consultation, and school assessments moderated by rescaling against a measure of scholastic aptitude in terms of their use as a basis for such selection. The value of each approach for students and tertiary institutions is considered and appropriate selection indices for each are described. Evidence of the validity of the scholastic aptitude measure for the rescaling task and of the predictive validity of all the different selection indices is provided. This evidence suggests that statistically rescaled teacher assessments predict tertiary success as effectively as external examinations.

Exploring and exploiting variety by environment (V × E) interaction is one of the major challenges facing plant breeders. In paper I of this series, we presented an approach to modelling V × E interaction in the analysis of complex multi-environment trials using factor analytic models. In this paper, we develop a range of statistical tools which explore V × E interaction in this context. These tools include graphical displays such as heat-maps of genetic correlation matrices as well as so-called E-scaled uniplots that are a more informative alternative to the classical biplot for large plant breeding multi-environment trials. We also present a new approach to prediction for multi-environment trials that include pedigree information. This approach allows meaningful selection indices to be formed either for potential new varieties or potential parents.

Benthic macroinvertebrates and three size classes of shortfinned eel (Anguilla australis, Anguillidae) were sampled in a lowland New Zealand stream over a 24-h period in summer to investigate diel feeding periodicity and prey selection. Fish of all three size classes fed mostly from post-dusk to dawn, with larger fish tending to consume a greater proportion of their prey during night-time. The number of prey taxa consumed increased with increasing size of fish. Prey selection indices indicated that: (1) the smallest eels (80–100 mm total length, TL) preferentially consumed ostracods (Crustacea) and larvae of Chironomidae (Diptera) and Psilochorema sp. (free-living Trichoptera); (2) medium-sized eels (101–199 mm TL) preferred larvae of Chironomidae, and Costachorema sp., Hydrobiosis sp. and Psilochorema sp.; and (3) large eels (200–300 mm TL) preferred ostracods, Psilochorema sp. and Hudsonema amabilis (cased Trichoptera). Eels of all size classes showed selection for soft-bodied or easily broken prey over those with hard cases which would have been more difficult to digest. There was considerable overlap in the diets of medium and large eels. Differences in the timing of feeding between the three size classes of eel are explained in terms of microhabitat use; differences in diet are explained in terms of prey size, and are also related to eel size.

Background: Notable advancements in the selection indices have led to the development of exceptional breeding strategies, which have eventually led to the selection of elite dairy animals. The comparison of trends is facilitated by their estimation which permit the assessment of progress in a particular trait. The purpose of this study was to investigate genetic trends in economic traits of Murrah buffaloes, which is predominantly present as a high milk producer using the regression method. The study was designed to estimate the phenotypic, genetic and environmental trends, which represent the changes accrued over time and hence, determines the efficiency of breeding programme. Methods: The present study was conducted on 659 Murrah buffaloes, sired by 188 bulls, over a period of 27 years (1991-2017). The economic traits studied were first lactation milk yield (FLMY), first lactation length (FLL), age at first calving (AFC), first calving interval (FCI), first service period (FSP) and first dry period (FDP). The phenotypic trends were obtained as regression of population performance on year and the genetic trends were obtained by Smith method I and II. Result: The results revealed that the phenotypic trends obtained were significant and desirable for all the traits except for first lactation length, which was non-significant. The standard errors obtained by Smith method-I were higher than those obtained from method-II. As the Smith method-II avoids year to year fluctuations in the environment and those of contemporaries, it gives more realistic estimate as compared to the first method with lower standard error.

Schools generally prepare class XII students to continue their studies at the higher education level, both official and non-official, this is done because almost 90% more high school students choose to continue their studies in higher education. In general, students take two selection courses at tertiary institutions, namely the national selection of state tertiary institutions (SNMPTN) and the joint selection of state tertiary institutions (SBMPTN). Both of these selections require intense preparation and guidance by the school conducted by the homeroom teacher and tutor. The purpose of this study is to find out whether the optimization of career services can improve the success of students who are accepted into state universities. This study uses qualitative methods, namely research procedures that produce descriptive data in the form of written or oral words from people or observable behavior. The study was conducted at SMA Muhammadiyah 2 Sidoarjo. In this study the source of the data obtained from interviews and observations to counseling guidance teachers, vice principals in the field of student affairs, public relations and school principals. Research data uses alumni data from Muhammadiyah 2 Sidoarjo High School from the 2015-2016 academic year until 2019 - 2020. Guidance and counseling have a very important role in helping the achievement of national education goals, and helping students achieve maximum potential development, independence in their lives, and decision making and choices to create a productive, prosperous and caring public welfare life.

High school alumni of the same level often experience difficulties in determining universities to continue their studies. The selection of tertiary institutions for equivalent high school alumni is constrained only by listening to talk, even often because of following friends. This is because there are so many types of criteria from universities that eventually make prospective students confused and choose without consideration. The selection of higher education institutions should be adjusted between the criteria of higher education and the needs and abilities of prospective students. This study uses an experimental model regarding the selection system of higher education selection decisions using the TOPSIS method. The purpose of this study is to help prospective students in the selection of universities to continue their studies. 7 criteria were obtained including Cost (BY) obtained from tuition fees, Accreditation Value (NA) obtained from the value of college accreditation, Achievement (PS) obtained from academic and non academic achievements, Lecturer Education (PD) obtained from education lecturers, facilities (FS) obtained from available facilities, scholarships (BS) obtained from scholarships at tertiary institutions and UKM (UK) obtained from student activity units available at the college. The results of this study can meet the objectives because the results of calculations can be faster in producing information that can help prospective students in choosing a college.

Nitrogen (N) limitation in maize crops is related to the fact that the efficiency of nitrogen fertilization in maize does not exceed 50%, primarily due to volatilization, denitrification and soil leaching. Therefore, the development of new nitrogen use efficient (NUE) cultivars is necessary. The aim of the present study was to develop indices for the accurate selection of NUE maize genotypes for use in conditions of both high and low N availability. The experiment was conducted in a greenhouse (20º45'14"S; 42º52'53"W) at the Federal University of Viçosa during October 2010. A total of 39 experimental hybrid combinations and 14 maize lines differing in NUE were evaluated under two N availability conditions. We determined the relative importance of the studied characters using principal component analysis, factor analysis and by developing efficient selection indices. We conclude that indirect and early selection of tropical maize genotypes can be performed using the indices I HN = 0.022 SDM + 0.35 RSDM + 0.35 RL A + 0.35 NUE for high N availability environments and I LN = -0.06 RSDM + 0.35 RSA A + 0.35 RL A + 0.39 SDM for low N availability environments.

In order to select superior hybrids for the concentration of favorable alleles for resistance to papaya black spot, powdery mildew and phoma spot, 67 hybrids were evaluated in two seasons, in 2007, in a randomized block design with two replications. Genetic gains were estimated from the selection indices of Smith & Hazel, Pesek & Baker, Williams, Mulamba & Mock, with selection intensity of 22.39%, corresponding to 15 hybrids. The index of Mulamba & Mock showed gains more suitable for the five traits assessed when it was used the criterion of economic weight tentatively assigned. Together, severity of black spot on leaves and on fruits, characteristics considered most relevant to the selection of resistant materials, expressed percentage gain of -44.15%. In addition, there were gains for other characteristics, with negative predicted selective percentage gain. The results showed that the index of Mulamba & Mock is the most efficient procedure for simultaneous selection of papaya hybrid resistant to black spot, powdery mildew and phoma spot.

The paper investigates the selection of courses of study by undergraduates of Valley View University, Kumasi. Data were collected from the school of social science education which focused on 10% of the total population, two hundred and ten (210). The data were analyzed using the Statistical Package for the Social Sciences (SPSS) version. Findings of the study reveal that economic influence has been found the most important allied to the desired choice of the programme of study. Other factors include school, peer and gender influence. It further argues that, for students to have access to their preferred program of study, there should be E-learning, academic guidance, orientation and avoidance of family influence. The study further recommends that families should serve as guides and support their wards in the selection of courses rather than imposing various programmes on them due to reasons such as sustainment of family business. In addition, Ghana Education Service (GES) should inculcate guidance and counseling into the Senior High School (SHS) syllabus to enhance prior knowledge on the selection of course or programme of study in the tertiary institutions and organizations of career exploration activities to help them decide on the programme of study.
