Job performance ratings: The relative importance of mental ability, conscientiousness, and career adaptability

According to career construction theory, continuous adaptation to the work environment is crucial to achieve work and career success. In this study, we examined the relative importance of career adaptability for job performance ratings using an experimental policy-capturing design. Employees (N = 135) from different vocational backgrounds rated the overall job performance of fictitious employees in 40 scenarios based on information about their career adaptability, mental ability, conscientiousness, and job complexity. We used multilevel modeling to investigate the relative importance of each factor. Consistent with expectations, career adaptability positively predicted job performance ratings, and this effect was relatively smaller than the effects of conscientiousness and mental ability. Job complexity did not moderate the effect of career adaptability on job performance ratings, suggesting that career adaptability predicts job performance ratings in high-, medium-, and low-complexity jobs. Consistent with previous research, the effect of mental ability on job performance ratings was stronger in high- compared to low-complexity jobs. Overall, our findings provide initial evidence for the predictive validity of employees' career adaptability with regard to other people's ratings of job performance.

Hintakäsitykset funktionaalisista elintarvikkeista ja euron käyttöönoton vaikutus

Työn tavoitteena oli tutkia kuluttajien hintakäsityksiä funktionaalisista elintarvikkeista sekä euron käyttöönoton vaikutuksia niihin. Teoriaosassa tarkasteltiin funktionaalisen elintarvikkeen käsitettä ja sen hintaan liittyviä kysymyksiä erikoistuotteen näkökulmasta sekä kuluttajan hintakäsityksen muodostumisessa tärkeää osaa näyttelevää referenssihintaa ja sen vaikutuksia sekä teoreettista taustaa, erityisesti adaptaatiotasoteoriaa. Lisäksi tarkasteltiin euron mahdollisia vaikutuksia referenssihintaan sekä referenssihinnan roolia kuluttajan hintakäsityksen muodostumisessa. Työn empiirinen osa koostui kahdesta kyselytutkimuksesta, jotka suoritettiin ennen euron käyttöönottoa joulukuussa 2001 ja sen jälkeen huhtikuussa 2002. Ensimmäiseen kyselyyn vastasi 182 ja toiseen 135 vastaajaa. Vastaajat olivat pääkaupunki- sekä Hämeenlinnan seudulta. Tutkimuksen kohteena olevat tuotteet olivat Gefilus®-piimä ja -mehut, ja kohderyhmänä niiden käyttäjät. Tutkimuksen empiirisessä osassa selvitettiin funktionaalisten elintarvikkeiden käyttö- ja ostotottumuksia sekä mielipidettä niiden hintatasosta suhteessa terveysvaikutuksiin ja tavallisiin elintarvikkeisiin. Referenssihintoja tutkimuksen kohteena oleville tuotteille tutkittiin sopivana, korkeimpana ja alhaisimpana hyväksyttävänä hintana.Euron vaikutuksia hintakäsityksiin tutkittiin vastausten eroissa kyselyjen välillä. Euron käyttöönoton aiheuttamia referenssihintojen muutoksia tarkasteltiin hintaherkkyysmittari avulla. Lisäksi tutkittiin euron käyttöönoton aiheuttamia muutoksia ostokäyttäytymisessä. Faktori- ja ryhmittelyanalyyseja käytettiin vastaajien ryhmittelyyn. Funktionaalisia elintarvikkeita pidettiin vastaajien joukossa kalliina suhteessa niiden terveysvaikutuksiin tai tavallisten, ei-funktionaalisten, tuotteiden hintaan. Tutkimuksen kohteena olleiden tuotteiden, Gefilus®-piimän ja -mehujen, hintatasoa pidettiin myös kalliina. Gefilus®-mehujen hintaa pidettiin yleisesti liian kalliina. Euron käyttöönotto aiheutti muutoksia vastaajien referenssihinnoissa. Euron käyttöönoton voitiin havaita vaikuttaneen kuluttajien hintakäsityksiin siten, että hinnat vaikuttivat aikaisempaa halvemmilta. Lisäksi euron käyttöönotto oli vaikeuttanut hintojen arviointia. Lähes kaikki vastaajat olivat sitä mieltä, että euron käyttöönoton jälkeen hinnat olivat nouseet. Euron käyttöönotto oli myös lisännyt pankkikortin käyttöä maksuvälineenä käteisen sijaan.

Structural Studies of Analgesics and Their Interactions. VIII.* Rotational Isomerism and Disorder in the Crystal Structure of Meelofenamie Acid

Meclofenamic acid, C I4HIICI2NO2, probably the most potent among analgesic fenamates, crystallizes in the triclinic space group P1, with a = 8.569 (5), b = 8.954(8), c -- 9.371 (4) A, ct = 103.0 (2), fl -- 103.5 (2), y = 92.4 (2) ° , Z = 2, D m = 1.43 (4), D c = 1.41 Mg m -3. The structure was solved by direct methods and refined to R = 0.135 for 1062 observed reflections. The anthranilic acid moiety in the molecule is nearly planar and is nearly perpendicular to the 2,6-dichloro-3-methylphenyl group. The molecules, which exist as hydrogen-bonded dimers, have an internal hydrogen bond involving the imino and the carboxyl groups. The methyl group is disordered and occupies two positions with unequal occupancies. The disorder can be satisfactorily explained in terms of the rotational isomerism of the 2,6-dichloro-3-methylphenyl group about the bond which connects it to the anthranilic acid moiety and the observed occupancies on the basis of packing considerations.

The status of entrepreneurship education in Australian universities

Purpose The purpose of this paper is to provide an analytical overview of the current state of entrepreneurship education (EE) in Australia; placing emphasis on programs, curricula and entrepreneurship ecosystems. Design/methodology/approach The authors performed a contextual review of the literature by delineating entrepreneurship education programs, the entrepreneurial ecosystem and EE learning and teaching. The review was enhanced by a systematic collection of data from higher education institutions web sites, depicting the prevailing situation of entrepreneurship programs, courses, subjects and their ecosystems. Findings A number of interesting findings emerged from this study. From a curricular perspective, Australian universities offer 584 subjects related to entrepreneurship. This includes dominance at undergraduate level, representing 24 minors/majors and specializations in entrepreneurship. In total, 135 entrepreneurship ecosystems were identified. Research limitations/implications This paper presents findings from university web sites and as such requires introspection to validate individual university offerings. Practical implications The study provides the status of EE in Australia, and may guide academic and policy decision makers to further develop entrepreneurship initiatives. Originality/value This paper provides the first analytical overview of EE in Australia and paves the way for further evaluation.

2,6-Lutidine-N-oxide complexes of rare-earth bromides

2,6-Lutidine-N-oxide (LNO) complexes of rare-earth bromides of the composition $$MBr_3 .(LNO)_{4_{ - n} } .nH_2 O$$ wheren = l for M = La, Pr, Nd, Sm, Gd, Ho, Er; andn = 0 for M = Y have been prepared and characterised by analyses, conductance and infrared data. Infrared spectra of the complexes indicate that the coordination of ligand to the metal ion takes place through the oxygen of the ligand, and the water molecule in the complexes present is coordinated to the metal. A coordination number of seven has been suggested to all the rare-earth metal ions.

The new binary pulsar and the observation of gravitational spin precession

The possibility of observing gravitational spin precession due to spin-orbit coupling in a binary pulsar system is considered. An analysis is presented which can aid in delineating the relevant physical effects from pulse-structure data. In this analysis, it is assumed that the pulsar radiation emanates from a cone whose axis is tilted with respect to the axis of rotation. It is found that the time-averaged pulse width and polarization sweep vary periodically with time and that this variation has a periodicity of the order of the spin-precession frequency averaged over a complete revolution. It is concluded that for an orbital period of about 180 years, it suffices to measure polarization data with an accuracy of a few parts in 100 over a period of six months to a year in order to uncover the effects of spin precession. The consistency of the analysis is checked, and the calculations are applied to a recently discovered binary pulsar.

Managing reforestation to sequester carbon, increase biodiversity potential and minimize loss of agricultural land

Reforestation will have important consequences for the global challenges of mitigating climate change, arresting habitat decline and ensuring food security. We examined field-scale trade-offs between carbon sequestration of tree plantings and biodiversity potential and loss of agricultural land. Extensive surveys of reforestation across temperate and tropical Australia (N = 1491 plantings) were used to determine how planting width and species mix affect carbon sequestration during early development (< 15 year). Carbon accumulation per area increased significantly with decreasing planting width and with increasing proportion of eucalypts (the predominant over-storey genus). Highest biodiversity potential was achieved through block plantings (width > 40 m) with about 25% of planted individuals being eucalypts. Carbon and biodiversity goals were balanced in mixed-species plantings by establishing narrow belts (width < 20 m) with a high proportion (>75%) of eucalypts, and in monocultures of mallee eucalypt plantings by using the widest belts (ca. 6–20 m). Impacts on agriculture were minimized by planting narrow belts (ca. 4 m) of mallee eucalypt monocultures, which had the highest carbon sequestering efficiency. A plausible scenario where only 5% of highly-cleared areas (<30% native vegetation cover remaining) of temperate Australia are reforested showed substantial mitigation potential. Total carbon sequestration after 15 years was up to 25 Mt CO2-e year−1 when carbon and biodiversity goals were balanced and 13 Mt CO2-e year−1 if block plantings of highest biodiversity potential were established. Even when reforestation was restricted to marginal agricultural land (<$2000 ha−1 land value, 28% of the land under agriculture in Australia), total mitigation potential after 15 years was 17–26 Mt CO2-e year−1 using narrow belts of mallee plantings. This work provides guidance on land use to governments and planners. We show that the multiple benefits of young tree plantings can be balanced by manipulating planting width and species choice at establishment. In highly-cleared areas, such plantings can sequester substantial biomass carbon while improving biodiversity and causing negligible loss of agricultural land.

Fracture Behavior of Multidirectional DCB Specimen: Higher-Order Beam Theories

Mathematical models, for the stress analysis of symmetric multidirectional double cantilever beam (DCB) specimen using classical beam theory, first and higher-order shear deformation beam theories, have been developed to determine the Mode I strain energy release rate (SERR) for symmetric multidirectional composites. The SERR has been calculated using the compliance approach. In the present study, both variationally and nonvariationally derived matching conditions have been applied at the crack tip of DCB specimen. For the unidirectional and cross-ply composite DCB specimens, beam models under both plane stress and plane strain conditions in the width direction are applicable with good performance where as for the multidirectional composite DCB specimen, only the beam model under plane strain condition in the width direction appears to be applicable with moderate performance. Among the shear deformation beam theories considered, the performance of higher-order shear deformation beam theory, having quadratic variation for transverse displacement over the thickness, is superior in determining the SERR for multidirectional DCB specimen.

Information technology and its changing roles to economic growth and productivity in Australia

In this paper we describe our investigation of the role of investment in information technology (IT) on economic output and productivity in Australia over a period of about four decades. The framework used in this paper is the aggregate production function, where IT capital is considered as a separate input of production along with non-IT capital and labour. The empirical results from the study indicate the evidence of robust technical progress in the Australian economy in the 1990s. IT capital had a significant impact on output, labour productivity and technical progress in the 1990s. In recent years, however, the contribution of IT capital on output and labour productivity has slowed down. Regaining the IT capital productivity therefore remains as a key challenge for Australia, especially in the context of greater IT investment in the future.

Purification and properties of a DNA polymerase from Mycobacterium tuberculosis H37Rv

DNA polymerase has been purified approximately 2000-fold from Mycobacterium tuberculosis H37Rv. The purified preparation was homogeneous by electrophoretic criteria and has a molecular weight of 135 000. The purified enzyme resembles Escherichia coli polymerase I in its properties, being insensitive to sulfhydryl drugs and possessing 5′,3′-exonuclease activity in addition to polymerase and 3′,5′-exonuclease activities. However, it differs from the latter in its sensitivity to higher salt concentration and DNA intercalating agents such as 8-aminoquinoline. The polymerase exhibited maximal activity between 37–42°C and pH 8.8–9.5. The polymerase was stable for several months below 0°C. However, the 5′,3′-exonuclease activity was more labile. The effects of different metal ions, polyamines and drugs on the polymerase activity are presented.
