Workplace Integrated Learning, Environmental Volunteering or Service Learning?

This discussion paper introduces the concept and practice of environmental volunteering as part of the process of Workplace Integrated Learning (WIL) at Edith Cowan University. As well as introducing the theoretical background and definitions of both volunteering and WIL, this paper describes examples from Natural Sciences domain of students doing environmental voluntary work with community groups as a practicum which is a core unit within their course. Literature suggests that these examples should neither be defined as volunteering nor WIL so their definitions and classifications are debated. Review of these examples in light of the literature suggests the conclusion that volunteering is a useful mechanism to support Workplace Integrated Learning for students who are studying in the domain of Natural Sciences. This paper introduces research that is being conducted into the attitudes of students about the volunteering aspect of the practicum and provides some qualitative comment from one of the 120 students currently enrolled

Environmental and Conservation Volunteering as Workplace Integrated Learning for University Students

This research paper introduces the concept and practice of tertiary sciences students doing environmental volunteering, also known as conservation volunteering, as a core part of their course. First year Natural Sciences students at Edith Cowan University do five days environmental volunteer work with community groups as a practicum, currently known as Workplace Integrated Learning (WIL). Initial research data displays the number of volunteer hours done by students in various types of activities, locations and organisations. Preliminary quantitative evaluations and qualitative comments demonstrate students’ positive attitudes and outcomes from their volunteering experiences. Definitions and classifications of volunteering and WIL from current literature are discussed as part of the curriculum design review process. Initial data from host organisations and students suggests that volunteering, and environmental volunteering in particular, can contribute to employability skills, although the program needs to be evaluated as one component of an integrated program of WIL that the students are required to complete. Students learn about potential careers and the environment industry’s reliance on volunteers. Students learn and practise specific skills (e.g. animal handling) and contribute to communities and the environment

University student volunteering alignment with sustainability principles

This research paper reviews the concept and practice of tertiary sciences students doing environmental volunteering, otherwise known as conservation volunteering, as a core part of their course to check its alignment with sustainability principles. First year Natural Sciences students at Edith Cowan University do five days environmental volunteer work with community groups as practicum. Initial research data displays the number of volunteer hours done by students in various types of activities, locations and organisations. Preliminary quantitative evaluations and qualitative comments demonstrate students’ positive attitudes and outcomes from their volunteering experiences. Definitions and classifications of sustainability from current literature are discussed as part of the curriculum design review process. Initial data from host organisations and students suggests that this environmental volunteering contributes to employability skills, although the program needs to be evaluated as one component of an integrated program of Work-Integrated Learning (WIL) that the students are required to complete. Students learn about potential careers and the environment industry’s reliance on volunteers. Students learn and practise specific skills (e.g. animal handling) and contribute to communities and the environment

The \u3ci\u3ePhycodnaviridae\u3c/i\u3e: The Story of How Tiny Giants Rule the World

The family Phycodnaviridae encompasses a diverse and rapidly expanding collection of large icosahedral, dsDNA viruses that infect algae. These lytic and lysogenic viruses have genomes ranging from 160 to 560 kb. The family consists of six genera based initially on host range and supported by sequence comparisons. The family is monophyletic with branches for each genus, but the phycodnaviruses have evolutionary roots that connect them with several other families of large DNA viruses, referred to as the nucleocytoplasmic large DNA viruses (NCLDV).The phycodnaviruses have diverse genome structures, some with large regions of noncoding sequence and others with regions of ssDNA. The genomes of members in three genera in the Phycodnaviridae have been sequenced. The genome analyses have revealed more than 1000 unique genes, with only 14 homologous genes in common among the three genera of phycodnaviruses sequenced to date. Thus, their gene diversity far exceeds the number of so-called core genes. Not much is known about the replication of these viruses, but the consequences of these infections on phytoplankton have global affects, including influencing geochemical cycling and weather patterns

Design of a ring resonator-based optical beam forming network for phased array receive antennas

A novel squint-free ring resonator-based optical beam forming network (OBFN) for phased array antennas (PAA) is proposed. It is intended to provide broadband connectivity to airborne platforms via geostationary satellites. In this paper, we present the design of the OBFN and its control system. Our goal is to deliver large bandwidth Ku-band connectivity between antennas, mount conformal to the airplane fuselage and on a geostationary satellite, respectively.This way it would be possible to bring live DVB-S television to airplane passengers. In this paper, we present recent research conducted on a 4 × 1 ring resonator-based OBFN test set-up. This OBFN has four optical input ports and one optical output port. It is tuned to provide the desired signal combination with optimal constructive interference between the modulated input signals from the PAA. Therefore, combining circuitry and delay elements are required. The OBFN is tuned by electrically heating tunable true time delay (TTD) elements. These are built using optical ring resonators (ORRs). By cascading multiple ORRs with different resonance frequencies, it is possible to create a TTD with a large bandwidth. Optical beam forming is used because it provides advantages over traditional beam forming methods. These advantages are: large bandwidth, EMI resistance, and, when integrated onto a single chip, compactness and low costs. The OBFN is created using planar optical waveguide technology and consists of the following building blocks: waveguides, Mach-Zehnder interferometers, (MZIs) couplers and ORRs. The tuning of the OBFN is done by an electronic control system using a microcontroller. Communication with a PC is possible using USB. To our knowledge, this is the first integrated ORR-based OBFN circuit for PAA satellite reception

Multidisciplinary decision-making in older patients with cancer, does it differ from younger patients?

Background: In order to tailor treatment to the individual patient, it is important to take the patients context and preferences into account, especially for older patients. We assessed the quality of information used in the decision-making process in different oncological MDTs and compared this for older (>70 years) and younger patients. Patients and methods: Cross-sectional observations of oncological MDTs were performed, using an observation tool in a University Hospital. Primary outcome measures were quality of input of information into the discussion for older and younger patients. Secondary outcomes were the contribution of different team members, discussion time for each case and whether or not a treatment decision was formulated. Results: Five-hundred and three cases were observed. The median patient age was 63 year, 32% were >70. In both age groups quality of patient-centered information (psychosocial information and patient's view) was poor. There was no difference in quality of information between older and younger patients, only for comorbidities the quality of information for older patients was better. There was no significant difference in the contributions by team members, discussion time (median 3.54 min) or number of decision reached (87.5%). Conclusion: For both age groups, we observed a lack of patient-centered information. The only difference between the age groups was for information on comorbidities. There were also no differences in contributions by different team members, case discussion time or number of decisions. Decision-making in the observed oncological MDTs was mostly based on medical technical information. (c) 2021 The Authors. Published by Elsevier Ltd.

Climate Change and the Integrity of Science

We are deeply disturbed by the recent escalation of political assaults on scientists in general and on climate scientists in particular. All citizens should understand some basic scientific facts. There is always some uncertainty associated with scientific conclusions; science never absolutely proves anything. When someone says that society should wait until scientists are absolutely certain before taking any action, it is the same as saying society should never take action. For a problem as potentially catastrophic as climate change, taking no action poses a dangerous risk for our planet. Scientific conclusions derive from an understanding of basic laws supported by laboratory experiments, observations of nature, and mathematical and computer modeling. Like all human beings, scientists make mistakes, but the scientific process is designed to find and correct them. This process is inherently adversarial—scientists build reputations and gain recognition not only for supporting conventional wisdom, but even more so for demonstrating that the scientific consensus is wrong and that there is a better explanation. That’s what Galileo, Pasteur, Darwin, and Einstein did. But when some conclusions have been thoroughly and deeply tested, questioned, and examined, they gain the status of “well-established theories” and are often spoken of as “facts.” We urge our policy-makers and the public to move forward immediately to address the causes of climate change, including the unrestrained burning of fossil fuels. We also call for an end to McCarthy-like threats of criminal prosecution against our colleagues based on innuendo and guilt by association, the harassment of scientists by politicians seeking distractions to avoid taking action, and the outright lies being spread about them. Society has two choices: We can ignore the science and hide our heads in the sand and hope we are lucky, or we can act in the public interest to reduce the threat of global climate change quickly and substantively. The good news is that smart and effective actions are possible. But delay must not be an option

Cloning, expression and chromosomal localization of a new putative receptor-like protein tyrosine phosphatase

AbstractWe have isolated a mouse cDNA of 5.7 kb, encoding a new member of the family of receptor-like protein tyrosine phosphatases, termed mRPTPμ. The cDNA predicts a protein of 1432 amino acids (not including signal peptide) with a calculated Mr of 161 636. In addition, we have cloned the human homologue, hRPTPμ, which shows 98.7% amino acid identity to mRPTPμ. The predicted mRPTPμ protein consists of a 722 amino acid extracellular region, containing 13 potential N-glycosylation sites, a single transmembrane domain and a 688 amino acid intracellular part containing 2 tandem repeats homologous to the catalytic domains of other tyrosine phosphatases. The N-terminal extracellular part contains a region of about 170 amino acids with no sequence similarities to known proteins, followed by one Ig-like domain and 4 fibronectin type III-like domains. The intracellular part is unique in that the region between the transmembrane domain and the first catalytic domain is about twice as large as in other receptor-like protein tyrosine phosphatases. RNA blot analysis reveals a single transcript, that is most abundant in lung and present in much lower amounts in brain and heart. Transfection of the mRPTPμ cDNA into COS cells results in the synthesis of a protein with an apparent Mr of 195 000, as detected in immunoblots using an antipeptide antibody. The human RPTPμ gene is localized on chromosome 18pter-q11, a region with frequent abnormalities implicated in human cancer
