Sickness Absence: An International Comparison

Previous attempts to analyse international differences in patterns of worker absenteeism have not been convincing because of the difficulty in obtaining internationally comparable data. In this paper, we apply the technique described by Barmby, Ercolani and Treble(1999) to data on full-time workers in 9 countries who have deposited Labour Force Survey returns with the Luxembourg Employment Study. We use the resulting dataset to verify relationships between absence and age, gender and other socio-economic characteristics of workers. These relationships prove to be similar across countries with widely differing mean rates of absence. Since our dataset uses individual observations we are also able to carry out a multivariate analysis of absence and its correlates. The most revealing result of the analysis is that the gender difference in absence rates that is apparent in the raw data is shown to be entirely due to differences in the age structures of the male and female workforce and their marital status.

Body size changes in passerine birds introduced to New Zealand from the UK

One feature of global geographic variation in avian body sizes is that they are larger on isolated islands than on continental regions. Therefore, this study aims to assess whether there have been changes in body size following successful establishment for seven passerine bird species (blackbird Turdus merula, song thrush T. philomelos, house sparrow Passer domesticus, chaffinch Fringilla coelebs, greenfinch Chloris chloris, goldfinch Carduelis carduelis, yellowhammer Emberiza citrinella) introduced from the continental islands of the UK to the more isolated oceanic landmass of New Zealand in the middle of the nineteenth century. Measures of tarsus length were taken from individuals from contemporary UK and New Zealand populations of these species, and from historical specimens collected around the time that individuals were translocated from the UK to New Zealand. Analysis of Variance was used to test for size differences between contemporary UK and New Zealand populations, and between historical UK and contemporary UK and New Zealand populations. Historical UK populations have longer tarsi, on average, than 12 (7 UK and 5 New Zealand) of the 14 contemporary populations. Significant decreases in tarsus length relative to the historical populations have occurred in the UK for blackbird, chaffinch and greenfinch, and in the New Zealand blackbird population. Contemporary New Zealand house sparrows have significantly longer tarsi, on average, than both historical and contemporary UK populations. Exposure to novel environments may be expected to lead to changes in the morphology and other traits of exotic species, but changes have also occurred in the native range. In fact, contrary to expectations, the most common differences we found were between contemporary and historical UK populations. Consideration of contemporary populations alone would underestimate the true scale of morphological change in these species over time, which may be due to phenotypic plasticity or genetic adaptation to environmental changes experienced by all populations in the last 150 years

DEECD Early Childhood Intervention Reform Project

This literature review was commissioned by the Office for Children and Early Childhood Development, Department of Education and Early Childhood Development (DEECD), as part of its Early Childhood Intervention Services (ECIS) Reform Project (Stage 2): Developing Options and Next Steps. This Project aims to significantly enhance the efficiency, effectiveness and sustainability of Victoria’s ECIS system and improve outcomes for children with a disability or developmental delay and their families. Early childhood intervention services (ECIS) support children with a disability or developmental delay from birth to school entry and their families. ECIS provides special education, therapy, counselling, service planning and coordination, assistance and support to access services such as kindergarten and child care. The services funded through DEECD are provided by government Specialist Children\u27s Services teams and non-government Early Childhood Intervention agencies. In addition to the services provided by ECIS teams and agencies, the state and federal governments fund a range of complementary programs to support young children with developmental disabilities and their families. These include initiatives to support families (My Time parent groups, Family Support Packages), services to support inclusion (Preschool Field Officers, Inclusion Support Facilitators), and funding to support particular disability groups (Helping Children with Autism packages). These additional services and supports, together with the ECIS teams and agencies, make up the totality of early childhood intervention provision for young children with disabilities. The focus of the literature review is research on contemporary Australian and international evidence-based service delivery models for children with a disability, developmental delay or additional needs aged 0-8 years

Betriebliche Fehlzeiten und Arbeitsverträge

"Der Beitrag zeigt, wie eine ökonomische Theorie der Fehlzeiten entwickelt werden könnte. Zunächst werden Fehlzeiten als Phänomen des Arbeitsangebots behandelt. Erörtert werden dabei die Struktur des Arbeitskräftepools, aus dem die Betriebe ihre Beschäftigten rekrutieren, die Gestaltung des Arbeitsvertrages und die Reaktion der Beschäftigten auf vertragliche Regelungen. Weiterhin werden betriebliche Entscheidungen über die Wahl der vertraglich festgelegten Arbeitszeit und die Kontrolle betrieblicher Fehlzeiten sowie die Reaktion der Arbeitskräfte auf die sich aus der Gestaltung der Arbeitsverträge und der betrieblichen Kontrollsysteme ergebenden Anreize analysiert. Schließlich werden Implikationen der theoretischen Überlegungen für empirische Studien und deren Interpretation entwickelt."

ZAC in GtoPdb v.2021.3

The zinc-activated channel (ZAC, nomenclature as agreed by the NC-IUPHAR Subcommittee for the Zinc Activated Channel) is a member of the Cys-loop family that includes the nicotinic ACh, 5-HT3, GABAA and strychnine-sensitive glycine receptors [2, 3, 4]. The channel is likely to exist as a homopentamer of 4TM subunits that form an intrinsic cation selective channel equipermeable to Na+, K+ and Cs+, but impermeable to Ca2+ and Mg2+ [4]. ZAC displays constitutive activity that can be blocked by tubocurarine and high concentrations of Ca2+ [4]. Although denoted ZAC, the channel is more potently activated by H+ and Cu2+, with greater and lesser efficacy than Zn2+, respectively [4]. ZAC is present in the human, chimpanzee, dog, cow and opossum genomes, but is functionally absent from mouse, or rat, genomes [2, 3]
