Early Segmentation Abilities in Preterm Infants

Infants born preterm have higher risks of developing linguistic deficits. Considering that the ability to segment words from fluent speech is crucial for lexical acquisition, Experiment 1 tested the ability of healthy extremely‐to‐late preterm infants to segment monosyllabic words at 6 months of postnatal age. Results establish basic segmentation skills in these infants. While we failed to find an effect of the degree of prematurity, this issue will need further exploration. Future studies will also have to specify the scope of these early segmentation skills, both in terms of the types of words segmented, the cues used to do so, and in terms of possible differences in performance between subgroups of preterm infants (e.g., based on gestational age or medical risks). Lastly, given that the preterm infants tested had a mean maturational age of 4 months, Experiment 2 explored monosyllabic segmentation in full‐term 4‐month olds. Infants succeeded at the task, providing the earliest developmental evidence of word segmentation in full‐term infants. These findings better specify the early trajectory of segmentation abilities in both full‐term and healthy, low‐risk preterm infants and support the proposal that prematurity might have a differential effect on the early acquisition of various linguistic levels.     

Ergonomic factors and production target evaluation in eucalyptus timber harvesting operations in mountainous terrains

There are several forest operations involved in Eucalyptus timber harvesting. This study was carried out during brush-cutting; tree felling, bucking, delimbing, piling and manual extraction operations, with the following objectives: a) analyzing, ergonomically, two systems of brush-cutting: one manual and the other semi-mechanized, using two different machines; b) ergonomically evaluating three different brands of pruner machines used in delimbing felled trees. c) determining the feasible target of productivity as a function of ergonomic factors relevant to establish the time of resting pauses for workers in manual and semi-mechanized timber harvesting systems in mountainous terrain. Brush-cutting, either manual or semimechanized, is an activity carried out prior to timber harvesting. It is usually a hard work, with low productivity when compared with mechanized systems. Pruner machines have been used by forest companies, due to the great possibilities to improve productivity, quality and the health of workers. Ergonomics is a discipline that promotes the adequacy of work to the physical and mental characteristics of human beings, seeking to design production systems and products considering relevant aspects, including social, organizational and environmental factors. Companies should consider the ergonomic factor in the determination of daily worker production targets.     

Elements of cultural competence in an Australian Aboriginal maternity program

Background

Pregnancy, labour and neonatal health outcomes for Australian Aboriginal women and their infants are frequently worse than those of the general population. Provision of culturally competent services may reduce these differences by improving access to timely and regular antenatal care. In an effort to address these issues, the Aboriginal Maternity Group Practice Program commenced in south metropolitan Perth, Western Australia, in 2011. The program employed Aboriginal Grandmothers, Aboriginal Health Officers and midwives working in a partnership model with pre-existing maternity services in the area.

Mental health support needs of people with a learning difficulty: a medical or a social model?

People with learning difficulties, like all disabled people, face social oppression. Much recent policy and practice are underpinned by at least some understanding of this oppression, and the social model of disability has been influential in discussions of services and supports for people with learning difficulties. However, in the area of mental health, the picture is somewhat different. This paper argues that the medical model has predominated in discussions of mental health support for people with learning difficulties, and that a social model approach could have much to offer. The paper draws on an ongoing action research study in which service providers, families and young people with learning difficulties are working together to articulate what is needed, in order to find routes to improve the support offered to young people with learning difficulties and mental health support needs.     

Collective and Unitary Models: A Clarification

In this note we identify and clarify a confusion that has arisen in the literature about the exact relationship between unitary and collective models and what enters the Pareto weight and the sharing function. We suggest that we should denote as ‘unitary’ any model that leads to outcomes that satisfy the Slutsky conditions whether or not these outcomes depend on distribution factors. In particular, income pooling is neither necessary nor sufficient for a unitary model. We also show that the presence of prices or total expenditure in the sharing rule cannot be used as a test for a unitary model.
