Teaching Methods As Correlate Of Student Performance In Business Studies In Selected Public Secondary Schools

One key responsibility of teachers especially of business study is to impart requisite skills/knowledge that will enable the student function well in the society of business as it prepares them for the world outside of school. If teaching method adopted in teaching are inadequat3e or ineffective, students’ academic performance will be low. The study therefore seeks to assess teaching methods as correlate of students’ Academic performance in Business Studies in Port Harcourt Local Government Area of Rivers State. Lecture method and discussion method were specifically used as representative of the two broad categories of teaching methods. To achieve the objective, the study adopted correlation research design using two research question and two null hypotheses. A sample of one hundred students from a randomly selected intact class of one randomly selected Junior Secondary school was used. Three items parallel forms of business studies achievement test were used for data collection and the test item validated by experts including two business educators and a test expert in measurement and evaluation from the Rivers State University. A reliability coefficient of 0.814 was obtained via a test – retest method applying Pearson Product Moment Correlation coefficient (PPMC) formula. this statistical tool was used in answering the research questions using r – values to determine weight of relationship between pre-test and post-test scores after using lecture and discussion methods respectively and to test the null hypotheses by comparing the calculated r-values and the critical r values of establish the significance of relationship at 98 for both lecture and freedom and 0.05 level of significance. Results revealed a coefficient of 0.70 and 0.92 for both lecture and discussion method indicating a significantly high positive relationship between pretest-test and post-test scores after using the two methods. Recommendation shows that teachers should continue to horme their skills, by attending workshops seminars and other teaching enhancing programmes and teachers should be aware of the rightful teaching methods to apply when one method is not effective.
Correlative Tomography – Combining x-ray nanotomography and FIB/SEM serial sectioning to analyze Al-Si cast alloys

Aluminium alloys with silicon as their major alloying element are widely used in die or sand casting of machine or vehicle parts. The microstructure of hypereutectic Al-Si alloys (>12% Si) consist of primary silicon particles and the Al-Si eutectic. Elements such as Cu, Mg and Ni are added in order to form a great variety of different intermetallic phases which improve mechanical properties at elevated temperatures. Size, shape and connectivity of these complexly formed intermetallic phases play a decisive role for the properties and are for that reason of great interest. As the complex shapes and connectivity are not accessible by means of classical 2D techniques, 3D analysis of the microstructure is mandatory. Due to the size of the particles in the ? mrange, only high resolution 3D imaging techniques are suitable. In this work we used 3D X-ray Microscopy as well as FIB/SEM Serial Sectioning to image the microstructure of an AlSi12Cu4Ni2Mg cast alloy. 3D images were taken at the very same sample volume in order to compare information gained from the different techniques.
Complete Post-Juvenile Moult in First-Year Blackcaps: Proximate Causes and Adaptive Implications

Summary. Moult is one of the most energy-demanding events in the annual cycle of a migratory bird. As a consequence, moult patterns have evolved that separate moult from other costly life-cycle stages and that exclude unnecessary replacement of the feathers. We studied two Spanish blackcap Sylvia atricapilla populations with the aim of elucidating variation and flexibility of their postjuvenile moult pattern. In contrast to most juveniles of this species, which normally undergo a partial moult both in captivity and in the wild, we found complete moult in 2 juvenile blackcaps. Complete moult was also inferred for another 7 birds, which were in active moult. Eight of these birds were trapped at a site in northern Spain and one originated from a partially migratory population from eastern Spain. This bird, held under the same environmental conditions as other 31 juveniles from the same population, moulted all primaries in captivity while the other 31 juveniles invariably undertook a normal partial post-juvenile moult. Therefore, it seems likely that complete post-juvenile moult observed in this bird was not induced by environmental conditions but had a genetic basis. Thus, we show that previously undetected variation among post-juvenile moult patterns is present in wild blackcaps and suggest that variation in the expression of important life-history traits could represent a potential reservoir for adaptive changes. This finding is in line with the great adaptive capacity of blackcap, repeatedly observed both in wild and in captivity.
A summary reconstruction of proto-maweti-guarani segmental phonology

This paper presents a succinct reconstruction of the segmental phonology of Proto-Maweti-Guarani, the hypothetical protolanguage from which modern Mawe, Aweti and the Tupi-Guarani branches of the Tupi linguistic family have evolved. Based on about 300 cognate sets from the authors' field data (for Mawe and Aweti) and from Mello's reconstruction (2000) for Proto-Tupi-Guarani (with additional information from other works; and with a few changes concerning certain doubtful features, such as the status of stem-final lenis consonants *r and *s, and the distinction of *c and *c ), the consonants and vowels of Proto-Maweti-Guarani were reconstructed with the help of the traditional historical-comparative method. The development of the reconstructed segments is then traced from the protolanguage to each of the modern branches. A comparison with other claims made about Proto-Maweti-Guarani is given in the conclusion.
Orthotrichum kellmanii (Bryopsida, Orthotrichaceae), A Remarkable New Species from the Central Coast of California

Abstract A new endemic moss from California is described and illustrated. The heterophyllous leaves and weakly cladocarpous growth pattern in crescent shaped cushions are distinctive features for this species. Although morphologically distinct from Orthotrichum, phylogenetic inferences based on variation in nucleotide sequences of the rbcL gene (cpDNA) suggest this species to be a member of Orthotrichum. Review of Orthotrichum specimens from California herbaria concluded that this species had not been collected previously. Orthotrichum kellmanii is currently restricted to a narrow band of sandstone outcrops on ridges overlooking the Pacific Ocean.
Bee Associates of Flowering Astragalus and Onobrychis Genebank Accessions at a Snake River Site in Eastern Washington

Abstract A 3 yr survey of the bee associates of flowering accessions of Astragalus and Onobrychis species was conducted in open-pollinated field nurseries at Central Ferry, Washington to gain insight into the potential for bee-mediated inter-accession out-crossing in these nurseries. Such nurseries are used by genebank managers at the USDA-ARS Western Regional Plant Introduction Station (WRPIS), Pullman, Washington, to multiply seed of accessions low in viability and/or supply. Fifty-two species of bees (Hymenoptera) in the Andrenidae (4 species), Apidae (18), Colletidae (1), Halictidae (5), and Megachilidae (24) were recorded. Species-rich genera were Bombus (8 species) and Osmia (16). One undescribed species of Osmia was collected. The bee fauna was more diverse on Astragalus (45 bee species) compared to Onobrychis (29 species). Among the 24 Astragalus and 13 Onobrychis species censused, bee diversity was highest on A. bungeanus Boiss. (24 bee species), A. chaborasicus Boiss. & Hausskn. (24 species), A. miser var. serotinus (A. Gray ex J.G. Cooper) Barney (14 species), A. cicer L. (13 species), A. schistosus Boiss. & Hohen. (12 species), A. onobrychis L. (11 species), A. podolobus Boiss. & Hohen. (11 species), and Onobrychis viciifolia Scop. (10 species). The presence of a rich bee fauna in WRPIS nurseries at Central Ferry, including documented pollinators of the allogamous species A. cicer and O. viciifolia, could complicate efforts to prevent hybridization and maintain genetic integrity of genebank accessions of allogamous plant species. Our results support a 1993 decision by WRPIS curators to discontinue the practice of clustering accessions of single species of Astragalus and Onobrychis in open-pollinated nurseries to regenerate seed.
Strategic Alliance and Local Content Development of Oil and Gas Producing Companies in Rivers State, Nigeria

This study examined the relationship between strategic alliance and local content development of oil and gas producing companies in Rivers State, Nigeria, the study adopted a cross-sectional survey research design to obtained responses from the oil and gas producing companies in Rivers State, Nigeria, using Krejcie & Morgan table, 1970 to determine the sample size. After data cleaning, 108 respondents were finally used for data analysis with the aid of statistical package for social science version 25.0. The regression analyses were used to test the research hypotheses. The empirical results showed that there is a variation in the relationship between strategic alliance and local content development in oil and gas producing companies that were studied. Specifically, the findings revealed that strategic alliance had a strong and positive significant relationship with the two measures of local content development such as: skill and technological development. The study thus, concluded that a strategic alliance had a positive and significant influence on local content development. Therefore, the study recommend that oil and gas producing companies should increase partnership that supports and facilitates learning and tacit knowledge transfer in vertical and horizontal strategic alliances and partnerships which would facilitate understanding, cooperation and successive implementation of ideas and systems by the organization.
Virtual care and telehealth for specific conditions

 Telehealth has been shown to improve access to care, is acceptable to patients and clinicians, and available technology can provide high-quality and secure information transfer.  The application of telehealth spans from the highly technical to the person centred and from time-limited acute encounters to ongoing episodes or series of care.  Strongest evidence is available for the acute management of ischaemic stroke via telestroke and for monitoring and management of chronic conditions such as diabetes and heart failure.  Tele-ICU, tele-mental health and tele-rehabilitation have also been associated with positive outcomes.  Much of the available evidence is of low quality.
INFLUENCE OF ORGANIC MANURE AND WOOD ASH ON THE ABUNDANCE OF SOIL MICROORGANISMS, ORGANIC CARBON AND GRAIN YIELD OF SOYBEAN (GLYCINE MAX L. MERRILL) IN ACID SOIL

Organic production methods which include the exclusion of chemical approach of soil amendment have been observed to improve plant growth and preserve the soil health and biodiversity of production environment. A study was conducted at the Federal University of Agriculture, Abeokuta, to examine the influence of organic manure and wood ash on the abundance of soil microorganisms, organic carbon and yield of soybean in acid soil. The study consisted of three rates of wood ash (0, 2.5 and 5.0 t ha-1) and three rates of cow dung (0, 5.0 and 10.0 t ha-1) arranged in completely randomized design, replicated three times. Soybean variety TGX 1485 – ID was sown into 5 kg. The results showed that wood ash application at 5.0 t ha-1 significantly increased the soil pH (6.6), organic carbon (7.48) and soil microbial population (110 × 104 cfu g-1) compared to lower rate of 2.5 t ha-1 and control, which resulted in highest number of pods (7.7) and grain yield (14.2 g per plant) at harvest. Cow dung treatment of 10 t ha-1 significantly had highest soil organic carbon (7.39%) at 8 WAP and soil microbial population (21.1 and 91.4 × 104 cfu g-1) at 4 and 8 WAP respectively. These findings indicate that application of wood ash may be an acceptable alternative liming agent to the inorganic soil amendment and higher soybean productivity.
Arbuscular mycorrhizal fungi associated with tissue culture raised potato.

In the present paper the types of arbuscular mycorrhizal propagules in the rhizosphere soil of the four different varieties of potato raised by meristem culturing method have been enlisted. A total of 29 species of Glomalean spores were recorded in the soil. Nineteen of these spores associated with potato crop were reported in the genus Glomus while two species each of Aculospora and Scutellospora and one each of Gigaspora and Sclerocystis were recorded. Four species could not be identified with the help of available diagnostic keys. Glomus mosseae and G. fasciculatum were scored having highest prevalence in the rhizosphere of all the progenies of four varieties studied.
Constructing a Unified Theory of Contemporary Australian Public Sector Management Reform

The literature on public sector management and accountability has had a great deal to contend with over the last decade or so. This is particularly the case in countries such as Australia which, along with New Zealand and the United Kingdom, have adopted far more radical and wide ranging public sector reforms than many other jurisdictions. Examples of such reforms include, but are not limited to, the introduction of accrual based accounting systems to replace traditional cash based systems, the implementation of budgeting systems focused on outputs and outcomes rather than inputs as well as the fusing of market or quasi market structures into institutions previously shielded from market disciplines. An extensive literature exists on each of the reforms nominated above, as well as other components of the overall reform process. However, the literature is fragmented. Thus, as an example, while reforms to budgetary processes have been analysed through theoretical lenses as diverse as critical management theory, public choice theory or political theory, the literature has been largely unsuccessful in locating and explaining individual reforms within their broader context. Because of the large number of different reform agendas which have been implemented in countries such as Australia over the past decade (and which continue to be implemented at a rapid rate), the literature surrounding these reforms has concentrated on the technical aspects of individual reforms. In order to advance the literature on public sector management reform, it is now necessary to begin the construction of a more unified theory of public management reform. Thus, reforms relating to asset valuation should no longer be viewed and explained only through the lens of accounting measurement theory, budgeting reforms should be explained in terms wider than simply public choice or political theories of budgetary construction, and so on. An alternative perspective on each of these changes to public sector management is to view them not as whole reforms in themselves, but rather, as part of the fabric of public management reform generally. This paper seeks to contribute to the literature by examining some of the linkages which exist between the individual components of public sector management and accountability reform which have been implemented in Australia over the past decade. In doing so it suggests that performance measurement in the public sector needs to be informed by the interconnection effects associated with simultaneous or near simultaneous implementation of multiple reform techniques.

Modeling and predicting aboveground biomass change in young forest using multi-temporal airborne laser scanner data

The aim of this study was to explore the ability of estimating change in total aboveground biomass (AGB) in young forests using multi-temporal airborne laser scanner data. A field data-set covering 11 growth seasons of 39 circular plots of size 200 m2 from young forest in south-eastern Norway was used in the analyses. Different approaches for prediction of the AGB change were tested. One approach was based on modeling AGB for each point in time and predicting change as the difference between separate AGB predictions. We also tested two approaches based on modeling and predicting change directly, and two approaches where growth/reduction rates were modeled and used in prediction. The approach where change was predicted as a difference between biomass predictions seemed to yield the best results (root mean square error [RMSE] 14.8%). The other approaches yielded results that were similar in terms of RMSE, except for the approach where AGB change was predicted using a growth rate. The results indicate that prediction of change as a difference between AGB predictions works satisfactory for a wide range of forest conditions, but that the direct approaches can perform better in some cases.
Genetic improvement of subterranean clover (Trifolium subterraneum L.). 1. Germplasm, traits and future prospects

Abstract. Subterranean clover (Trifolium subterraneum L.) is the most widely sown annual pasture legume species in southern Australia, valued in the livestock and grains industries as a source of high-quality forage and for its ability to fix atmospheric nitrogen. From its initial accidental introduction into Australia in the 19th Century and subsequent commercialisation in the early 1900s, 45 cultivars have been registered in Australia. These consist of 32 cultivars of ssp. subterraneum, eight of ssp. yanninicum, and five of ssp. brachycalycinum and range in flowering time from 77 to 163 days from sowing, enabling the species to be grown in a diversity of rainfall environments, soil types, and farming systems. Eleven of these cultivars are introductions from the Mediterranean region, 15 are naturalised strains collected in Australia, 18 are the products of crossbreeding, and one is derived from mutagenesis. Cultivars developed in Italy have been commercialised for the local market, whereas other cultivars developed in Spain, Portugal, and France have not had commercial seed production. Important traits exploited include: (i) selection for low levels of the oestrogenic isoflavone formononetin, which causes reduced ewe fertility; (ii) increased levels of dormancy imposed by seed-coat impermeability (hard seeds) for cultivars aimed at crop rotations or unreliable rainfall environments; (iii) strong burr-burial ability to maximise seed production; (iv) resistance to important disease pathogens for cultivars aimed at medium- and high-rainfall environments, particularly to Kabatiella caulivora and root rot pathogens; (v) resistance to pests, particularly redlegged earth mites; and (vi) selection for unique leaf markings and other morphological traits (where possible) to aid cultivar identification. Cultivar development has been aided by a large genetic resource of ∼10 000 accessions, assembled from its centre of origin in the Mediterranean Basin, West Asia, and the Atlantic coast of Western Europe, in addition to naturalised strains collected in Australia. The development of a core collection of 97 accessions, representing almost 80% of the genetic diversity of the species, and a genetic map, provides a platform for development of future cultivars with new traits to benefit the livestock and grains industries. New traits being examined include increased phosphorous-use efficiency and reduced methane emissions from grazing ruminant livestock. Economic analyses indicate that future trait development should focus on traits contributing to increased persistence and autumn–winter productivity, while other potential traits include increased nutritive value (particularly of senesced material), increased N2 fixation ability, and tolerance to cheap herbicides. Beneficial compounds for animal and human health may also be present within the species for exploitation.
MEAN-PERFORMANCE, INTERRELATIONSHIPS AND PATH ANALYSIS OF YIELD TRAITS IN BREAD WHEAT (TRITICUM AESTIVUM L.) CROSSES

Heterosis, heterobeltiosis and inbreeding depression for grain yield and its components were studied through 6 crosses in F1 and F2 generations. These crosses were resulted from half diallel mating design between 4 different parents in 2014/2015. In 2017/2018 season, an experiment was conducted in randomized complete block design with three replications at Faculty of Agriculture, Cairo University, Giza, Egypt to evaluate the 16 genotypes (4 parental lines and their 6 crosses in F1 and 6 crosses in F2). Moreover, simple phenotypic correlation and path analysis were performed to study the nature of associations between grain yield and its components. The results showed that, for grain yield plant-1, the cross combination (P2 × P3) depicted the highest significant and positive heterosis (88.12%) and heterobeltiosis (81.9%) followed by cross combination (P1 xP2) which exhibited a high positive significant heterosis (83.43%) and high positive significant heterobeltiosis (60.35%). Concerning inbreeding depression, highly significant and positive values of inbreeding depression were detected for total dry matter, spike dry matter, grain yield plant-1 and 1000-kernels weight for all crosses. On the other hand, significant and negative values of inbreeding depression were detected in plant height, No. of spikes plant-1, spike length, harvest index and No. of kernels spike-1. Respect to the correlation analysis. The results showed that, highly significant and positive correlation was observed between grain yield plant-1 and each of No. of spikes plant-1 (r=0.64**), biological yield (r=0.94**), spike dry matter (r=0.98**) and 1000-kernels weight (r=0.76**). Concerning path-analysis technique, the spike number plant-1 exhibited the highest direct effect value (0.61) towards grain yield plant-1 followed by number of kernels spike-1 which exhibited a high degree of direct effect (0.547). The greatest indirect effect on grain yield plant-1 was achieved by total dry matter via number of spikes plant-1. It could be concluded that, plant height, number of spikes plant-1, spike length, No. of kernels spike-1 and 1000-kernels weight are major components of wheat yield and could be used as selection criteria in the breeding programs.
