Recruiting/hiring of older workers

This chapter reviews five key components of the recruitment process with regard to an aging workforce. First, targeted recruitment entails that organizations understand the needs, preferences, and strengths of older workers. Second, the recruitment message should communicate job and organizational characteristics that are attractive to older jobseekers. Third, the recruitment source should be consistent with the mediayse and job-search behaviors of older jobseekers. Fourth, the characteristics and behaviors of recruiters play an essential role in the recruitment of older applicants. Finally, organizations need to convey an attractive image of themselves as employers for older workers. Throughout the chapter, best practices are contrasted with available research evidence, and directions for future research are outlined.

Early Childhood teachers’ work in a time of change

This article investigates teacher decision-making in a time of rapid educational reforms. Institutional ethnography is used to discover how teachers’ work is co-ordinated by the texts of a new national curriculum, and a system for the assessment and ratings of kindergarten, preschool and long day-care services in individual settings and across sites. The research draws on video recorded interview data gathered from five teachers working with three to five year old children in kindergarten classrooms throughout South East Queensland. Analysis shows the reported effects of policy regimes designed to improve the quality of learning young children experience, on classroom teachers’ work. Findings suggest that increasing levels of governance enacted through policy texts are creating an audit culture where teachers’ educational work with children is changing. The article argues that the reported workload associated with the production of evidence, and the focus on providing ‘proof’ of quality, is taking teachers away from time spent building educative relationships with children. Note: In Queensland, kindergarten caters for children aged three and a half to five years. This year is known as Preschool in some Australian states.

Kristallivalheita : Itsepetos filosofisen tulkinnan lähtökohtana eräissä draaman klassikoissa

The philosophical problem of self-deception focuses the relation between desire, advantage, evidence and harm. A self-deceptive person is irrational because he or she belives or wants to belive contrary to the available evidence. The study focuses on different forms of self-deception that come out in certain classical Western dramas. The first self-deception forms are: "S knows that ~p but still belives that p because he wants that ~p", "S wants that p and therefore belives that p.", "S belives that p against evidence t because he wants to belive that p.", "S belives that p if t but S would belive that p even if ~t because S wants to belive that p.", "S belives that p (even if there is t that ~p) because S is ignorant of it." and "S belives that p (even if there is t that ~p) because of ignorant of t due to an internal deception." The main sources on self-deception are the views of contemporary researchers of the subject, such as Robert Audi, Marcia Baron, Bas C. van Fraassen, Mark Johnston, Mike W. Martin, Brian MaLaughlin, Alfred Mele, Amélie Oksenberg Rorty, William Ruddick and Stephen L. White. In this study it is claimed that Shakespeare´s Othello presents self-deception as a tragic phenomenom from witch it follows deceptions and murders. Moliére´s Tartuffe deals with a phony hypocrite´s attempts at cheating. Ibsen´s Wild Duck defends the necessity of vital lies. Beckett´s Waiting for Godot deals with the self-deception witch is related to the waiting of the supernatural rescuer. Miller´s The Death of a Salesman tells about a man who, while pursuing the American myth of success, winds both himself and his family into the skeins of self-deception. They are studied with a Barthesian method that emphasizes the autonomy of literary work and its interpretation independently of the author´s personal history and social conditions. Self-deception has been regarded as an immoral way of thinking or way of action. However, vital lies show the necessity or necessity of the self-deception when it brings joy and optimism to the human being and supports his or her self-esteem and does not cause a suffering or damage, either to self or others. In the study, the processual character of self-deception is brought out.

The doctrinal method: Incorporating interdisciplinary methods in reforming the law

The doctrinal methodology is in a period of change and transition. Realising that the scope of the doctrinal method is too constricting, academic lawyers are becoming eclectic in their use of research method. In this transitional time, legal scholars are increasingly infusing evidence (and methods) from other disciplines into their reasoning to bolster their reform recommendations. This article considers three examples of the interplay of the discipline of law with other disciplines in the pursuit of law reform. Firstly the article reviews studies on the extent of methodologies and reformist frameworks in PhD research in Australia. Secondly it analyses a ‘snapshot’ of recently published Australian journal articles on criminal law reform. Thirdly, it focuses on the law reform commissions, those independent government committees that play such an important role in law reform in common law jurisdictions. This examination demonstrates that while the doctrinal core of legal scholarship remains intact, legal scholars are endeavouring to accommodate statistics, comparative perspectives, social science evidence and methods, and theoretical analysis, within the legal research framework, in order to provide additional ballast to the recommendations for reform.

Criminal intent

The High Court recently heard submissions of counsel in Zaburoni v The Queen. This case concerns an appeal against conviction for transmitting a serious disease with intent under section 317(b) and (e) of the Queensland Criminal Code. It raises important issues about the meaning of intent and how intent can be proven in Queensland criminal offences. Since intent is an element of so many of the more serious crimes, it is surprising to see that the courts, both in England and Australia, continue to grapple with how best to define it. In murder, for example, the accused is potentially going to be locked up for a very long time, so it is essential that the courts and juries are very clear on what intent actually means, so that they can be confident in correctly finding that it was present on the facts of the case.

Teacher quality in upper secondary science education in Australia

Science education has been the subject of increasing public interest over the last few years. While a good part of this attention has been due to the fundamental reshaping of school curricula and teacher professional standards currently underway, there has been a heightened level of critical media commentary about the state of science education in schools and science teacher education in universities. In some cases, the commentary has been informed by sound evidence and balanced perspectives. More recently, however, a greater degree of ignorance and misrepresentation has crept into the discourse. This chapter provides background on the history and status of science teacher education in Australia, along with insights into recent developments and challenges.

Zaburoni HIV case: The law can sometimes be an ass, but not in this case

Lana Nowakowski's opinion piece on the High Court decision in the Zaburoni HIV case attacks "Queensland's absurd necessity to prove intention on transmission" and argues that "changes to the law are long overdue". Both claims are wrong...

Antipyrine complexes of rare-earth nitrates

Antipyrine complexes of eight rare-earth nitrates of the composition M(C11H12N2O)3 (NO3)3 where M = La, Ce, Pr, Nd, Sm, Gd, Er, and Y, have been prepared by a new, simple method and characterised. The complexes undergo exothermic decomposition at ~3oo°C. Infrared and U.V. spectral studies of the complexes indicate that antipyrine coordinates to metal through oxygen. The nature of the nitrate bonding is discussed in the light of infrared evidence, and conductivity studies in nitromethane and dimethylformamide.

Geometrically Nonlinear Dynamics of Composite Four-Bar Mechanisms

This work intends to demonstrate the importance of geometrically nonlinear crosssectional analysis of certain composite beam-based four-bar mechanisms in predicting system dynamic characteristics. All component bars of the mechanism are made of fiber reinforced laminates and have thin rectangular cross-sections. They could, in general, be pre-twisted and/or possess initial curvature, either by design or by defect. They are linked to each other by means of revolute joints. We restrict ourselves to linear materials with small strains within each elastic body (beam). Each component of the mechanism is modeled as a beam based on geometrically nonlinear 3-D elasticity theory. The component problems are thus split into 2-D analyses of reference beam cross-sections and nonlinear 1-D analyses along the four beam reference curves. For thin rectangular cross-sections considered here, the 2-D cross-sectional nonlinearity is overwhelming. This can be perceived from the fact that such sections constitute a limiting case between thin-walled open and closed sections, thus inviting the nonlinear phenomena observed in both. The strong elastic couplings of anisotropic composite laminates complicate the model further. However, a powerful mathematical tool called the Variational Asymptotic Method (VAM) not only enables such a dimensional reduction, but also provides asymptotically correct analytical solutions to the nonlinear cross-sectional analysis. Such closed-form solutions are used here in conjunction with numerical techniques for the rest of the problem to predict multi-body dynamic responses, more quickly and accurately than would otherwise be possible. The analysis methodology can be viewed as a three-step procedure: First, the cross-sectional properties of each bar of the mechanism is determined analytically based on an asymptotic procedure, starting from Classical Laminated Shell Theory (CLST) and taking advantage of its thin strip geometry. Second, the dynamic response of the nonlinear, flexible fourbar mechanism is simulated by treating each bar as a 1-D beam, discretized using finite elements, and employing energy-preserving and -decaying time integration schemes for unconditional stability. Finally, local 3-D deformations and stresses in the entire system are recovered, based on the 1-D responses predicted in the previous step. With the model, tools and procedure in place, we shall attempt to identify and investigate a few problems where the cross-sectional nonlinearities are significant. This will be carried out by varying stacking sequences and material properties, and speculating on the dominating diagonal and coupling terms in the closed-form nonlinear beam stiffness matrix. Numerical examples will be presented and results from this analysis will be compared with those available in the literature, for linear cross-sectional analysis and isotropic materials as special cases.

Geometrically non-linear dynamics of composite four-bar mechanisms

This is carried out by varying stacking sequences (i.e. the arrangement of ply orientations within a laminate) and material properties, and speculating on the dominating diagonal and coupling terms in the closed-form non-linear beam stiffness matrix. A numerical example is presented which illustrates the importance of 2-D cross-sectional non-linearities and the behavior of the system is also observed by using commercial software (I-DEAS + NASTRAN + ADAMS).

ORTHOPYROXENE plus SILLIMANITE PREDATING SAPPHIRINE plus QUARTZ: A RARE CASE OF ULTRAHIGH-TEMPERATURE METAMORPHISM FROM THE CENTRAL ZONE, LIMPOPO COMPLEX, SOUTH AFRICA

Sapphirine + quartz and orthopyroxene + sillimanite occur in garnet from an Mg-Al granulite from the Central Zone of the Limpopo Complex in South Africa. Textural evidence and a chemical gradient in garnet between the zones preserving the inclusions argue for the formation of sapphirine + quartz after orthopyroxene + sillimanite. Petrological observations, pressure-temperature phase diagrams, and compositional and model proportion results on isopleths indicate the sapphirine + quartz + garnet + orthopyroxene (high-Al) assemblage as the peak metamorphic assemblage (similar to 1050 degrees C at similar to 8.5 kbars), whereas orthopyroxene (low-Al) + sillimanite represents the prograde stage (at ca. 900 degrees C at similar to 8.5 kbars). Our report of these two diagnostic ultrahigh-temperature mineral assemblages in garnet from an Mg-Al granulite is unique, given the rare occurrence of sapphirine + quartz postdating orthopyroxene + sillimanite assemblage in granulites.

Design of double toggle switching mechanisms

Toggle mechanisms are ubiquitous in electrical switches. However, literature for their mechanical design is scarce. This paper defines and classifies the toggle phenomena observed during switching. The concept of double toggle introduced in this paper enables a systematic screening of kinematic structure for the suitability in high performance switches. Seven structural and three kinematic criteria are identified for this purpose. It is also demonstrated that each such feasible kinematic structure lends itself to multiple physical embodiments. Therefore, the theory and procedure presented in this work can be used for design of numerous kinematically distinct mechanisms. One representative mechanical embodiment for a novel double toggle switch, including mass and geometric shape of links has been included in the paper. The switching behavior of the design is validated using Pro/Mechanism (TM). (C) 2013 Elsevier Ltd. All rights reserved.

Reconstruction of Two-Dimensional Spectra from One-Dimensional Projections-Examples from Solid State NMR

The use of Projection Reconstruction (PR) to obtain two-dimensional (2D) spectra from one-dimensional (1D) data in the solid state is illustrated. The method exploits multiple 1D spectra obtained using magic angle spinning and off-magic angle spinning. The spectra recorded under the influence of scaled heteronuclear scalar and dipolar couplings in the presence of homonuclear dipolar decoupling sequences have been used to reconstruct J/D Resolved 2D-NMR spectra. The use of just two 1D spectra is observed sufficient to reconstruct a J-resolved 2D-spectrum while a Separated Local Field (SLF) 2D-NMR spectrum could be obtained from three 1D spectra. The experimental techniques for recording the 10 spectra and procedure of reconstruction are discussed and the reconstructed results are compared with 20 experiments recorded in traditional methods. The application of the technique has been made to a solid polycrystalline sample and to a uniaxially oriented liquid crystal. Implementation of PR-NMR in solid state provides high-resolution spectra as well as leads to significant reduction in experimental time. The experiments are relatively simple and are devoid of several technical complications involved in performing the 2D experiments.

Mycobacterium tuberculosis RecG Protein but Not RuvAB or RecA Protein Is Efficient at Remodeling the Stalled Replication Forks IMPLICATIONS FOR MULTIPLE MECHANISMS OF REPLICATION RESTART IN MYCOBACTERIA

Aberrant DNA replication, defects in the protection, and restart of stalled replication forks are major causes of genome instability in all organisms. Replication fork reversal is emerging as an evolutionarily conserved physiological response for restart of stalled forks. Escherichia coli RecG, RuvAB, and RecA proteins have been shown to reverse the model replication fork structures in vitro. However, the pathways and the mechanisms by which Mycobacterium tuberculosis, a slow growing human pathogen, responds to different types of replication stress and DNA damage are unclear. Here, we show that M. tuberculosis RecG rescues E. coli Delta recG cells from replicative stress. The purified M. tuberculosis RecG (MtRecG) and RuvAB(MtRuvAB) proteins catalyze fork reversal of model replication fork structures with and without a leading strand single-stranded DNA gap. Interestingly, single-stranded DNA-binding protein suppresses the MtRecG- and MtRuvAB-mediated fork reversal with substrates that contain lagging strand gap. Notably, our comparative studies with fork structures containing template damage and template switching mechanism of lesion bypass reveal that MtRecG but not MtRuvAB or MtRecA is proficient in driving the fork reversal. Finally, unlike MtRuvAB, we find that MtRecG drives efficient reversal of forks when fork structures are tightly bound by protein. These results provide direct evidence and valuable insights into the underlying mechanism of MtRecG-catalyzed replication fork remodeling and restart pathways in vivo.
