Impacts of the Suai Supply Base Project in Timor-Leste

Based on field research in early 2015, this In Brief provides a preliminary overview of the differentiated impacts the project is likely to have, and concludes that the land expropriation process for the Suai Supply Base runs the risk of: severely impoverishing local households, increasing inequality between and within households, and leading to marginalisation and social disarticulation (Cernea 2000). Issues highlighted in this In Brief will be explored in depth in a future SSGM Discussion Paper.AusAI

Land Politics under Timor-Leste's New Government

Earlier this year, Xanana Gusmão stepped down as prime minster of Timor-Leste, appointing Dr Rui Araújo, a well-respected member of the opposition, to replace him. The long-awaited change in Timor- Leste’s political leadership is underpinned by the reconciliation between Gusmão and opposition leader, Mari Alkatiri, who have both agreed to step aside into new roles. These enticing new roles ensure their respective control over the country’s two largest economic development projects (the Oecusse Special Economic Zone and the Tasi Mane South Coast Petroleum Development Project). This In Brief examines how the change in government and the role of these two powerful figures in state-driven economic development might affect political will to legislate on land issues. It argues that the legislative lethargy of the past few years is a result of significant political economy factors.AusAI

An electric fence? Assessing the impact of Brexit on the single electricity market in Ireland

A great deal of attention during the Brexit negotiations has been focused on the issue of the Irish border. However, as Meabh Cormacain writes, Brexit also has important implications for Northern Ireland's participation in the Single Electricity Market that currently exists across the island of Ireland. She highlights that despite widespread agreement on the importance of the Single Electricity Market after Brexit, we are still some distance from agreement on the detailed policies, codes, regulations and practices required to underpin the electricity market on the island

A qualitative analysis of parental coping with an early diagnosis of hearing loss in Ireland

The recent implementation of Universal Neonatal Hearing Screening (UNHS) in all 19 maternity hospitals across Ireland has precipitated early identification of paediatric hearing loss in an Irish context. This qualitative, grounded theory study centres on the issue of parental coping as families receive and respond to (what is typically) an unexpected diagnosis of hearing loss in their newborn baby. Parental wellbeing is of particular concern as the diagnosis occurs in the context of recovery from birth and at a time when the parent-child relationship is being established. As the vast majority of children with a hearing loss are born into hearing families with no prior history of deafness, parents generally have had little exposure to childhood hearing loss and often experience acute emotional vulnerability as they respond to the diagnosis. The researcher conducted in-depth interviews primarily with parents (and to a lesser extent with professionals), as well as a follow-up postal questionnaire for parents. Through a grounded theory analysis of data, the researcher subsequently fashioned a four-stage model depicting the parental journey of receiving and coping with a diagnosis. The four stages (entitled Anticipating, Confirming, Adjusting and Normalising) are differentiated by the chronology of service intervention and defined by the overarching parental experience. Far from representing a homogenous trajectory, this four-stage model is multifaceted and captures a wide diversity of parental experiences ranging from acute distress to resilient hopefulnes

Probiotics and mastitis: evidence-based marketing?

Probiotics are defined as live micro-organisms, which when administered in adequate amounts, confer health benefits on the host. Scientists have isolated various strains of Lactobacilli from human milk (such as Lactobacillus fermentum and Lactobacillus salivarius), and the presence of these organisms is thought to be protective against breast infections, or mastitis. Trials of probiotics for treating mastitis in dairy cows have had mixed results: some successful and others unsuccessful. To date, only one trial of probiotics to treat mastitis in women and one trial to prevent mastitis have been published. Although trials of probiotics to prevent mastitis in breastfeeding women are still in progress, health professionals in Australia are receiving marketing of these products. High quality randomised controlled trials are needed to assess the effectiveness of probiotics for the prevention and/or treatment of mastitis

Evaluation of Irish Consumers’ Knowledge of Salmonellosis and Foodhandling Practices

Salmonella is one of numerous food-borne pathogens that could possibly pose a major threat to global food safety. Salmonella is primarily associated with foods such as poultry, eggs, vegetables, and some dairy products. However, infected food handlers and faecal contaminated environments are also significant sources and reservoirs of this pathogen. This study comprehensively evaluated the Irish consumers’ food safety knowledge by exploring their knowledge level, practices and attitudes regarding raw meat handling, cross-contamination while handling different types of food products, and knowledge of Salmonella risk and associated food-handling practices. The online SurveyMonkey tool was used to distribute a quantitative survey titled “Evaluation of Knowledge and Food-handling practices of Irish Consumers” from July to November 2020 and generated a total of 1916 responses. Results indicated that 79.9% of the studied Irish population had a good knowledge of salmonellosis and risk perception related to food handling practices. Knowledge of cross-contamination, hygienic practices and pathogens associated with poultry were also considered high. However, knowledge of meat handling was low at 44.9%. It was also observed that age, gender, marital status, gross annual income, and nationality were influential factors regarding the food safety knowledge of consumers, while age, marital status and gender indicated significant differences regarding awareness of correct food hygiene practices

Advances in Engineering Human Tissue Models

Research in cell biology greatly relies on cell-based in vitro assays and models that facilitate the investigation and understanding of specific biological events and processes under different conditions. The quality of such experimental models and particularly the level at which they represent cell behavior in the native tissue, is of critical importance for our understanding of cell interactions within tissues and organs. Conventionally, in vitro models are based on experimental manipulation of mammalian cells, grown as monolayers on flat, two-dimensional (2D) substrates. Despite the amazing progress and discoveries achieved with flat biology models, our ability to translate biological insights has been limited, since the 2D environment does not reflect the physiological behavior of cells in real tissues. Advances in 3D cell biology and engineering have led to the development of a new generation of cell culture formats that can better recapitulate the in vivo microenvironment, allowing us to examine cells and their interactions in a more biomimetic context. Modern biomedical research has at its disposal novel technological approaches that promote development of more sophisticated and robust tissue engineering in vitro models, including scaffold- or hydrogel-based formats, organotypic cultures, and organs-on-chips. Even though such systems are necessarily simplified to capture a particular range of physiology, their ability to model specific processes of human biology is greatly valued for their potential to close the gap between conventional animal studies and human (patho-) physiology. Here, we review recent advances in 3D biomimetic cultures, focusing on the technological bricks available to develop more physiologically relevant in vitro models of human tissues. By highlighting applications and examples of several physiological and disease models, we identify the limitations and challenges which the field needs to address in order to more effectively incorporate synthetic biomimetic culture platforms into biomedical research

Acceleration of Digital Pre- Distortion Training Using Selective Partitioning

In recent years model and Digital Pre-Distortion dimension reduction has been widely researched. The oper- ations involved when running DPD are often far less than those needed during the training of the DPD coefficients. The proposed partitioned Least Squares (LS) adaptation allows a selected subset of DPD coefficients to be updated while the remaining coefficients are held constant. This technique allows a more adaptive training procedure, improved interpretability of the important DPD coefficient’s during training and the ability to partition the DPD function into specific groups. The Frisch-Waugh-Lovell (FWL) theorem is exploited to partition the coefficients of a DPD basis function trained using LS regression. The proposed methodology was experimentally validated with a Generalized Memory Polynomial (GMP) DPD function, used to linearize a 5W power amplifier (PA) driven by a 40MHz 5G-NR signal

Exploring Musical Activities and Their Relationship to Emotional Well-Being in Elderly People across Europe : A Study Protocol

Music is a powerful, pleasurable stimulus that can induce positive feelings and can therefore be used for emotional self-regulation. Musical activities such as listening to music, playing an instrument, singing or dancing are also an important source for social contact, promoting interaction and the sense of belonging with others. Recent evidence has suggested that after retirement, other functions of music, such as self-conceptual processing related to autobiographical memories, become more salient. However, few studies have addressed the meaningfulness of music in the elderly. This study aims to investigate elderly people's habits and preferences related to music, study the role music plays in their everyday life, and explore the relationship between musical activities and emotional well-being across different countries of Europe. A survey will be administered to elderly people over the age of 65 from five different European countries (Bosnia and Herzegovina, Czechia, Germany, Ireland, and UK) and to a control group. Participants in both groups will be asked about basic sociodemographic information, habits and preferences in their participation in musical activities and emotional well-being. Overall, the aim of this study is to gain a deeper understanding of the role of music in the elderly from a psychological perspective. This advanced knowledge could help to develop therapeutic applications, such as musical recreational programs for healthy older people or elderly in residential care, which are better able to meet their emotional and social needs.Peer reviewe

Does Candida and/or Staphylococcus play a role in nipple and breast pain in lactation? A cohort study in Melbourne, Australia

Objective: To investigate Candida species and Staphylococcus aureus and the development of \u27nipple and breast thrush\u27 among breastfeeding women. Design: Prospective longitudinal cohort study. Setting: Two hospitals in Melbourne, Australia (one public, one private) with follow-up in the community. Participants: 360 nulliparous women recruited at 36 weeks\u27 gestation from November 2009 to June 2011. Participants were followed up six times: in hospital, at home weekly until 4 weeks postpartum and by telephone at 8 weeks. Main outcome measures: Case definition \u27nipple and breast thrush\u27: burning nipple pain and breast pain (not related to mastitis); detection of Candida spp (using culture and PCR) in the mother\u27s vagina, nipple or breast milk or in the baby\u27s mouth; detection of S aureus in the mother\u27 nipple or breast milk. Results: Women with the case definition of nipple/ breast thrush were more likely to have Candida spp in nipple/breast milk/baby oral samples (54%) compared to other women (36%, p=0.014). S aureus was common in nipple/breast milk/baby samples of women with these symptoms as well as women without these symptoms (82% vs 79%) (p=0.597). Time-to-event analysis examined predictors of nipple/breast thrush up to and including the time of data collection. Candida in nipple/breast milk/baby predicted incidence of the case definition (rate ratio (RR) 1.87 (95% CI 1.10 to 3.16, p=0.018). We do not have evidence that S aureus colonisation was a predictor of these symptoms (RR 1.53, 95% CI 0.88 to 2.64, p=0.13). Nipple damage was also a predictor of these symptoms, RR 2.30 (95% CI 1.19 to 4.43, p=0.012). In the multivariate model, with all three predictors, the RRs were very similar to the univariate RRs. This indicates that Candida and nipple damage are independent predictors of our case definition
