Assessing self-responsibility in employability competencies development among Australian engineering students: introductory report

Self-responsibility study initially outlined the importance of ‘self-directed Adult learning’ either as the method or the outcome of education. Attention was given to the different interest of individual’s in accepting responsibility for their professional development. In this regard, several sources reveal the need for learners to take their own responsibility for developing employability competencies development. However, the concern must be expressed at the incompleteness of research into the personal responsibility for competency development

Dynamic allometry in coastal overwash morphology

Allometry refers to a physical principle in which geometric (and/or metabolic) characteristics of an object or organism are correlated to its size. Allometric scaling relationships typically manifest as power laws. In geomorphic contexts, scaling relationships are a quantitative signature of organization, structure, or regularity in a landscape, even if the mechanistic processes responsible for creating such a pattern are unclear. Despite the ubiquity and variety of scaling relationships in physical landscapes, the emergence and development of these relationships tend to be difficult to observe - either because the spatial and/or temporal scales over which they evolve are so great or because the conditions that drive them are so dangerous (e.g. an extreme hazard event). Here, we use a physical experiment to examine dynamic allometry in overwash morphology along a model coastal barrier. We document the emergence of a canonical scaling law for length versus area in overwash deposits (washover). Comparing the experimental features, formed during a single forcing event, to 5 decades of change in real washover morphology from the Ria Formosa barrier system, in southern Portugal, we find differences between patterns of morphometric change at the event scale versus longer timescales. Our results may help inform and test process-based coastal morphodynamic models, which typically use statistical distributions and scaling laws to underpin empirical or semi-empirical parameters at fundamental levels of model architecture. More broadly, this work dovetails with theory for landscape evolution more commonly associated with fluvial and alluvial terrain, offering new evidence from a coastal setting that a landscape may reflect characteristics associated with an equilibrium or steady-state condition even when features within that landscape do not.Funding Agency NERC Natural Environment Research Council NE/N015665/2 Leverhulme Trust RPG-2018-282info:eu-repo/semantics/publishedVersio

SWINE PRODUCTION NETWORKS IN MINNESOTA: RESOURCES FOR DECISION MAKING

Swine production networks are becoming a significant part of the Minnesota swine industry, with at least 30 production networks in operation as of late 1995. There are probably at least 450 producers involved, representing at least nine percent of the state s sow inventory. Not counted in these numbers are a few other networks involved only in data-sharing or marketing as well as a large number of farmer-to-farmer custom/contract arrangements. We interviewed 20 producers involved in networks. None of the networks we surveyed had been in operation very long, with most in business no more than a year or two. It is too early to predict what their long-term success will be. Most of the respondents seemed pleased with the arrangements so far. An example financial analysis of a 1,400 sow network is presented in the paper. Pig pricing formulas and custom rates are discussed for sharing risks among the farrower, nursery and finisher members of the network. The staff paper is 34 pages plus a 26 page annotated reading list of other publications on networking and segregated early weaning.Livestock Production/Industries,

Cosmic ray modulation and turbulent interaction regions near 11 AU

When Voyager 2 was near 11 AU, the counting rate of nuclei approx 75 MeV/nucleon decreased during the interval from July, 1982 to November, 1982, and it increased thereafter until August, 1983. A decrease in cosmic ray flux was generally associated with the passage of an interaction region in which the magnetic field strength B was higher than that predicted by the spiral field model, B sub p. Several large enhancements in B/B sup p were associated with merged interaction regions which probably resulted from the interaction of two or more distinct flows. During the passage of interaction regions the cosmic ray intensity decreased at a rate proportional to (B/B sup p -1), and during the passage of rarefaction regions (where B/B sup p 1) the cosmic ray intensity increased at a constant rate. The general form of the cosmic ray intensity profile during this approx 13 month minicycle can be described by integrating these relations using the observed B(t). Latitudinal variations of the interaction regions and of the short-term cosmic ray variations were identified

Kultur in Vitro Endosperma, Protokol Yang Efisien Untuk Mendapatkan Tanaman Triploid Secara Langsung

In Vitro Culture of Endosperm: An efficient protocol topropagate triploid plants directly. L. Agus Sukamto.Triploid plants are very vigorous and beneficial since theygenerally produce seedless fruits, bigger flowers, and producemore volume of wood than the diploid counterparts.The triploid plants can be produced by crossing diploid andtetraploid plants, but this method is cumbersome and takesa long time. In vitro culture of endosperm is an alternativemethod to produce triploid plants directly. The success ofendosperm culture is dependent on many factors, such asmaturity of endosperm, presence of the zygotic embryo, culturemedium, growth regulators, browning, culture period,an plant species. Generally, a mature endosperm needs aninitial association with an embryo to induce cell divisions,while proliferation of an immature endosperms is notdependent on the embryo. Endosperm of most parasiticangiosperms shows direct organogenesis without callusformation. Plants produced from endosperm culture aregenerally triploid, although some plants possess differentploidy levels

A low-mass faraday cup experiment for the solar wind

Faraday cups have proven to be very reliable and accurate instruments capable of making 3-D velocity distribution measurements on spinning or 3-axis stabilized spacecraft. Faraday cup instrumentation continues to be appropriate for heliospheric missions. As an example, the reductions in mass possible relative to the solar wind detection system about to be flown on the WIND spacecraft were estimated. Through the use of technology developed or used at the MIT Center for Space Research but were not able to utilize for WIND: surface-mount packaging, field-programmable gate arrays, an optically-switched high voltage supply, and an integrated-circuit power converter, it was estimated that the mass of the Faraday Cup system could be reduced from 5 kg to 1.8 kg. Further redesign of the electronics incorporating hybrid integrated circuits as well as a decrease in the sensor size, with a corresponding increase in measurement cycle time, could lead to a significantly lower mass for other mission applications. Reduction in mass of the entire spacecraft-experiment system is critically dependent on early and continual collaborative efforts between the spacecraft engineers and the experimenters. Those efforts concern a range of issues from spacecraft structure to data systems to the spacecraft power voltage levels. Requirements for flight qualification affect use of newer, lighter electronics packaging and its implementation; the issue of quality assurance needs to be specifically addressed. Lower cost and reduced mass can best be achieved through the efforts of a relatively small group dedicated to the success of the mission. Such a group needs a fixed budget and greater control over quality assurance requirements, together with a reasonable oversight mechanism
