Anneke Tooten, Hannah N Hoffenkamp, Ruby AS Hall, Frans Winkel, Marij Eli?ns, Ad JJM Vingerhoets, Hedwig JA van Bakel
BMC Pediatrics , 2012, DOI: 10.1186/1471-2431-12-76
Abstract: This study is a multi-center randomised controlled trial to evaluate the effectiveness of Video Interaction Guidance in parents of premature infants. In this study 210 newborn infants with their parents will be included: n?=?70 healthy term infants (>37?weeks GA), n?=?70 moderate term infants (32–37?weeks GA) which are recruited from maternity wards of 6 general hospitals and n?=?70 extremely preterm infants or very low birth weight infants (<32?weeks GA) recruited by the NICU of 2 specialized hospitals. The participating families will be divided into 3 groups: a reference group (i.e. full term infants and their parents, receiving care as usual), a control group (i.e. premature infants and their parents, receiving care as usual) and an intervention group (i.e. premature infants and their parents, receiving VIG). The data will be collected during the first six months after birth using observations of parent-infant interactions, questionnaires and semi-structured interviews. Primary outcomes are the quality of parental bonding and parent-infant interactive behaviour. Parental secondary outcomes are (posttraumatic) stress symptoms, depression, anxiety and feelings of anger and hostility. Infant secondary outcomes are behavioral aspects such as crying, eating, and sleeping.This is the first prospective study to empirically evaluate the effect of VIG in parents of premature infants. Family recruitment is expected to be completed in January 2012. First results should be available by 2012.NTR3423Each year, 2% to 9% of the newborns require specialised care in neonatal intensive care units (NICU). The majority are premature infants (born before 37?weeks of gestational age) who weigh less than 2500?g at birth. Modern medical technology has forced back the frontiers of viability so that a growing number of babies, even as young as 23 to 24?weeks gestation with weights as low as 500 gram, are currently surviving [1]. With the improved survival chance of preterm infants, there i
“Expectant Parents”: Study protocol of a longitudinal study concerning prenatal (risk) factors and postnatal infant development, parenting, and parent-infant relationships

BMC Pregnancy and Childbirth , 2012, DOI: 10.1186/1471-2393-12-46
Abstract: The present study is a prospective longitudinal cohort study, in which pregnant women (N?=?466) and their partners (N?=?319) are followed from 15 weeks gestation until their child is 24 months old. During pregnancy, midwives register the presence of prenatal risk factors and provide obstetric information after the child’s birth. Parental characteristics are investigated using self-report questionnaires at 15, 26, and 36 weeks gestational age and at 4, 6, 12, and 24 months postpartum. At 26 weeks of pregnancy and at 6 months postpartum, parents are interviewed concerning their representations of the (unborn) child. At 6 months postpartum, the mother-child interaction is observed in several situations within the home setting. When children are 4, 6, 12, and 24 months old, parents also completed questionnaires concerning the child’s (social-emotional) development and the parent-child relationship. Additionally, at 12 months information about the child’s physical development and well-being during the first year of life is retrieved from National Health Care Centres.The results of this study may contribute to early identification of families at risk for adverse parent-infant relationships, infant development, or parenting. Thereby this study will be relevant for the development of policy, practice, and theory concerning infant mental health.Developmental research has firmly established the quality of the relationship between an infant and his or her parent as an important factor influencing the child’s later development [1-6]. When children develop a secure relationship with their parents or caregivers in their first years of life, they generally have better cognitive outcomes, better social interactions, display less behavioral problems, and achieve better at school [7]. Research in this area has mainly investigated the attachment relationships that infants form with their parents, thus focusing on the child’s perspective of the relationship. In contrast, the attachment
Quality of the parent-child interaction in young children with type 1 diabetes mellitus: study protocol

BMC Pediatrics , 2011, DOI: 10.1186/1471-2431-11-28
Abstract: First, we will examine which situations are most suitable for observing diabetes-specific interactions. Then, these situations will be video-taped in a pilot study (N = 15). Observed behaviors are described into rating scales, with each scale describing characteristics of parent-child interactional behaviors. Next, we apply the observational tool on a larger scale for further evaluation of the instrument (N = 120). The parents are asked twice (with two years in between) to fill out questionnaires about psychosocial functioning of their child with T1DM. Furthermore, glycemic control (HbA1c) will be obtained from their medical records.A disease-specific observational tool will enable the detailed assessment of the quality of diabetes-specific parent-child interactions. The availability of such a tool will facilitate future (intervention) studies that will yield more knowledge about impact of parent-child interactions on psychosocial functioning, and glycemic control of children with T1DM.Results of The Diabetes Control and Complications Trial (DCCT) have convincingly shown that keeping blood glucose levels close to normal levels avoids or delays the onset of long-term complications of diabetes [1]. When young children are diagnosed with type 1 diabetes mellitus (T1DM), parents get full responsibility for the diabetes-management of their child (e.g., blood glucose monitoring and administering insulin, regulation of food intake, and guarding the level of physical activity of their diabetic child). Normal and age appropriate behaviors that occur in the toddler and pre-school years (e.g. independence-seeking, refusing food, oppositional behavior) can interfere with the ability of parents to complete the tasks needed to achieve optimal blood glucose control [2]. This interference and the full responsibility of the parents may affect family functioning and parent-child interaction [3-5].An overview by Anderson et al. [6] showed that when a child suffers from a chronic condi
Impact of the WFD on agriculture in the Netherlands and possible effect-specific hydrological measures: the Dutch approach
Jan van Bakel
Journal of Water and Land Development , 2006, DOI: 10.2478/v10025-007-0004-8
Abstract: The European Water Framework Directive can have enormous consequences for agriculture in the Netherlands. In parts of the country agriculture should be taken out of production because the nutrient loads to the surface water system are far too high. This doom scenario is of course undesired and a number of source-specific and effect-specific measures are necessary. The fate of nutrients in the soil is strongly interrelated with its hydrology. Directly, because nutrients are transported by water and the distribution of the residence time of drainage water is a good measure for the time behaviour of the nutrient loads to the surface water system. Longer residence time in the soil means more of nutrients applied by farmers but also a longer recovery period, after applying source-specific measures. In this paper three promising effect-specific hydrological measures are described buffer strips, retention strips, and controlled drainage.
Sound and Complete Typing for lambda-mu
Steffen van Bakel
Electronic Proceedings in Theoretical Computer Science , 2011, DOI: 10.4204/eptcs.45.3
Abstract: In this paper we define intersection and union type assignment for Parigot's calculus lambda-mu. We show that this notion is complete (i.e. closed under subject-expansion), and show also that it is sound (i.e. closed under subject-reduction). This implies that this notion of intersection-union type assignment is suitable to define a semantics.
Reduction in X does not agree with Intersection and Union Types (Extended abstract)
Steffen van Bakel
Computer Science , 2011,
Abstract: This paper defines intersection and union type assignment for the calculus X, a substitution free language that enjoys the Curry-Howard correspondence with respect to Gentzen's sequent calculus for classical logic. We show that this notion is closed for subject-expansion, and show that it needs to be restricted to satisfy subject-reduction as well, making it unsuitable to define a semantics.

Semantic Predicate Types and Approximation for Class-based Object Oriented Programming
Steffen van Bakel,Reuben N. S. Rowe
Computer Science , 2011,
Abstract: We apply the principles of the intersection type discipline to the study of class-based object oriented programs and; our work follows from a similar approach (in the context of Abadi and Cardelli's Varsigma-object calculus) taken by van Bakel and de'Liguoro. We define an extension of Featherweight Java, FJc and present a predicate system which we show to be sound and expressive. We also show that our system provides a semantic underpinning for the object oriented paradigm by generalising the concept of approximant from the Lambda Calculus and demonstrating an approximation result: all expressions to which we can assign a predicate have an approximant that satisfies the same predicate. Crucial to this result is the notion of predicate language, which associates a family of predicates with a class.
Note on a simple type system for non-interference
Steffen van Bakel,Maria Grazia Vigliotti
Computer Science , 2011,
Abstract: We consider CCS with value passing and elaborate a notion of noninterference for the process calculi, which matches closely that of the programming language. The idea is to view channels as information carriers rather than as "events", so that emitting a secret on output channel can be considered safe, while inputting a secret may lead to some kind of leakage. This is in contrast with the standard notion of noninterference for the process calculi where any causal dependency of low-level action from any high-level action is forbidden.
Proceedings Third International Workshop on Classical Logic and Computation
Steffen van Bakel,Stefano Berardi,Ulrich Berger
Computer Science , 2011, DOI: 10.4204/EPTCS.47
Abstract: The fact that classical mathematical proofs of simply existential statements can be read as programs was established by Goedel and Kreisel half a century ago. But the possibility of extracting useful computational content from classical proofs was taken seriously only from the 1990s on when it was discovered that proof interpretations based on Goedel's and Kreisel's ideas can provide new nontrivial algorithms and numerical results, and the Curry-Howard correspondence can be extended to classical logic via programming concepts such as continuations and control operators. The workshop series "Classical Logic and Computation" aims to support a fruitful exchange of ideas between the various lines of research on computational aspects of classical logic. This volume contains the abstracts of the invited lectures and the accepted contributed papers of the third CL&C workshop which was held jointly with the workshop "Program Extraction and Constructive Mathematics" at the University of Brno in August 21-22, 2010, as a satellite of CSL and MFCS. The workshops were held in honour of Helmut Schwichtenberg who became "professor emeritus" in September 2010. The topics of the papers include the foundations, optimizations and applications of proof interpretations such as Hilbert's epsilon substitution method, Goedel's functional interpretation, learning based realizability and negative translations as well as special calculi and theories capturing computational and complexity-theoretic aspects of classical logic such as the lambda-mu-calculus, applicative theories, sequent-calculi, resolution and cut-elimination
