Evaluating inputs for organic farming – a new system. Proposals of the ORGANIC INPUTS EVALUATION project

This volume contains proposals for criteria for evaluation of plant protection products, fertilisers and soil conditioners1 to be used in organic agriculture. These ideas were developed in the course of the European Union (EU) Concerted Action project ‘ORGANIC INPUTS EVALUATION’ (QLK5-CT-2002-02565). For more information on this project see the end of this volume or visit the project website www.organicinputs.org. The documents in this volume are proposals elaborated by the project consortium and external experts. They were discussed with a broader audience at a public conference held in Brussels on October 13, 2005, and have been amended accordingly. Our proposals also include a “criteria matrix”, which is in Microsoft Excel format, and therefore stands as a separate file. The criteria matrix is discussed in section 5, but we strongly recommend that you consult the original document. To illustrate the use of the matrix, we have further prepared two case studies, which are also separate Excel files. All of these files are contained on the CD, and can also be downloaded from the project website. Currently, Regulation 2092/91 is under revision. We hope that our ideas can be incorporated into the regulation during this revision! In addition, we strongly encourage national institutions to make use of our proposals at the national level

Protocol for the effectiveness evaluation of an antenatal, universally offered, and remotely delivered parenting programme ‘Baby Steps’ on maternal outcomes : a Born in Bradford’s Better Start (BiBBS) study

BACKGROUND: Poor perinatal mental health and maternal sensitivity towards a child in the early years can carry a long-term cost to individuals and to society, and result in negative child outcomes such as poor mental health and social emotional issues. Despite the recognition of early intervention and prevention, there is mixed evidence regarding antenatal parenting interventions that aim to enhance perinatal mental health and maternal sensitivity to prevent negative child outcomes. ‘Baby Steps’ is a relationship-based antenatal and postnatal parenting programme. The service evaluated in this study is delivered in a low-income and ethnically diverse community via Better Start Bradford. This study aims to assess whether the universally, and remotely delivered Baby Steps programme is effective in improving postnatal maternal sensitivity (primary outcome) and postnatal maternal mental health (secondary outcome) when compared to services as usual 6–10 weeks post-birth. It will also assess differences in birth outcomes, and differences in the prevalence of poor perinatal mental ill health through routine data. The feasibility of collecting cost and health related resource use data for a future economic evaluation will be explored. METHODS: The study is a quasi-experimental evaluation in a single centre. All participants are drawn from Born in Bradford’s Better Start (BiBBS) interventional family cohort study. Intervention participants will be matched to a demographically comparable control group using propensity score matching. The required minimum sample is n = 130 (ratio 1:1) to detect a medium effect (± 2.35, d = .50) on the primary outcome—maternal-child sensitivity, using the Mothers Object Relations Scale Short Form (MORS-SF). Secondary outcomes include the Patient Health Questionnaire (PHQ-8), Generalised Anxiety Disorder assessment 7 (GAD-7), identification of poor perinatal mental health through routine data, and birth outcomes (delivery method, gestation period, low birth weight). Service delivery costs and health resource use will be gathered from routine data. DISCUSSION: This study will evaluate the effectiveness of Baby Steps for enhancing maternal-child sensitivity and maternal mental health when delivered universally and remotely. The findings regarding programme effectiveness, process, and costs will be relevant for researchers, service commissioners, and service staff. TRIAL REGISTRATION: This study was prospectively registered with ISRCTN (22/04/2022, ISRCTN12196131).

Análise técnica e econômica do equipamento Stump Harvester

Orientador: Prof. Dr. Ricardo Anselmo MalinovskiMonografia (graduação) - Universidade Federal do Paraná,Setor de Ciências Agrárias, Curso de Engenharia Florestal.Resumo: As atividades de colheita florestal comumente geram uma grande quantidade de resíduos em plantios florestais de Pinus spp. e Eucalyptus spp, prejudicando as operações silviculturais. Dentre todos os tipos de resíduos florestais, os tocos constituem um grande dificultador das operações de implantação florestal como subsolagem, fertilização, plantio e manutenção. A redução da qualidade das operações pode levar à uma redução na área de efetivo plantio, reduzindo o número de árvores plantadas por hectare e subutilizando o sítio. Diante disso, buscam-se alternativas para remoção e aproveitamento de resíduos florestais. Quanto a remoção de tocos, uma alternativa atual é o equipamento stump harvester que consiste em um implemento específico para a remoção de tocos montado em uma escavadeira hidráulica. Diante disso, o presente trabalho avaliou técnica e economicamente o equipamento stump harvester para a reforma e realinhamento de plantios de Pinus taeda e Eucalyptus dunnii em uma empresa florestal do norte de Santa Catarina. Foram avaliados a produtividade, custos, receitas e indicadores econômicos no intuito de avaliar a viabilidade do investimento no equipamento. Como resultado de produtividade obteve-se uma média de 3,88 e 3,19 tocos/min para o Pinus taeda e Eucalyptus dunnii, respectivamente. O custo de remoção foi calculado em 1.521,47 R$/ha para o Pinus taeda e 1.778,72 R$/ha para o Eucalyptus dunnii. Foram estimadas diversas situações de aumento de receitas com a utilização do equipamento. Quando utilizado somente para fins de reforma e realinhamento o uso do equipamento é inviável a uma taxa mínima de atratividade de 10%. Recomenda-se, entretanto, a quantificação e qualificação do material extraído para a produção de biomassa, pois, segundo literatura especializada, existe um grande potencial energético nesse material

Barriers and facilitators in the delivery of a proportionate universal parenting program model (E-SEE Steps) in community family services

Background A proportionate universal (PU) approach to early years’ service provision has been advocated to improve children’s health and development and to reduce health inequality, by ensuring that services provide timely and high-quality parenting support commensurate with need. Process-oriented research is critical to examine the factors that contribute to, or hinder, the effective delivery/implementation of such a model in community-based family services. This study aimed to assess the delivery, acceptability and feasibility of a new PU parenting intervention model (called E-SEE Steps), using the Incredible Years® (IY) parent program, when delivered by trained health/family service staff in three “steps”—one universal step (the IY Babies Book), and two targeted steps (group-based IY Infant and Toddler programs). Methods An embedded mixed-methods process evaluation within a pragmatic parallel two-arm, assessor blinded, randomized controlled trial was conducted in community services in four local authorities in England. The process evaluation used qualitative data gathered via interviews and focus groups with intervention arm parents who were offered the targeted steps (n = 29), practitioners (n = 50), service managers (n = 7) and IY program mentors (n = 3). This was supplemented by quantitative data collected using group leader pre-training (n = 50) and post-delivery (n = 39) questionnaires, and research notes of service design decisions. Results The E-SEE Steps model was acceptable to most parents, particularly when it was accompanied by engagement strategies that supported attendance, such as providing childcare. Practitioners also highlighted the positive development opportunities provided by the IY training and supervision. However, participant views did not support the provision of the IY Babies book as a standalone universal component, and there were barriers to eligible parents—particularly those with low mood—taking up the targeted programs. Service providers struggled to align the PU model with their commissioned service contracts and with their staff capacity to engage appropriate parents, including tackling common barriers to attendance. Conclusions Despite general enthusiasm and support for delivering high-quality parenting programs in community services in the England, several barriers exist to successfully delivering IY in a proportionate universal model within current services/systems

Toward homochiral protocells in noncatalytic peptide systems

The activation-polymerization-epimerization-depolymerization (APED) model of Plasson et al. has recently been proposed as a mechanism for the evolution of homochirality on prebiotic Earth. The dynamics of the APED model in two-dimensional spatially-extended systems is investigated for various realistic reaction parameters. It is found that the APED system allows for the formation of isolated homochiral proto-domains surrounded by a racemate. A diffusive slowdown of the APED network such as induced through tidal motion or evaporating pools and lagoons leads to the stabilization of homochiral bounded structures as expected in the first self-assembled protocells.Comment: 10 pages, 5 figure

The mTORC1 inhibitor everolimus prevents and treats Eμ-Myc lymphoma by restoring oncogene-induced senescence

MYC deregulation is common in human cancer. IG-MYC translocations that are modeled in EμMyc mice occur in almost all cases of Burkitt lymphoma as well as in other B-cell lymphoproliferative disorders. Deregulated expression of MYC results in increased mTOR complex 1 (mTORC1) signaling. As tumors with mTORC1 activation are sensitive to mTORC1 inhibition, we used everolimus, a potent and specific mTORC1 inhibitor, to test the requirement for mTORC1 in the initiation and maintenance of EμMyc lymphoma. Everolimus selectively cleared premalignant B cells from the bone marrow and spleen, restored a normal pattern of B-cell differentiation, and strongly protected against lymphoma development. Established EμMyc lymphoma also regressed after everolimus therapy. Therapeutic response correlated with a cellular senescence phenotype and induction of p53 activity. Therefore, mTORC1-dependent evasion of senescence is critical for cellular transformation and tumor maintenance by MYC in B lymphocytes

Measuring the impact and costs of a universal group based parenting programme : protocol and implementation of a trial

Background Sub-optimal parenting is a common risk factor for a wide range of negative health, social and educational outcomes. Most parenting programmes have been developed in the USA in the context of delinquency prevention for targeted or indicated groups and the main theoretical underpinning for these programmes is behaviour management. The Family Links Nurturing Programme (FLNP) focuses on family relationships as well as behaviour management and is offered on a universal basis. As a result it may be better placed to improve health and educational outcomes. Developed in the UK voluntary sector, FLNP is popular with practitioners, has impressed policy makers throughout the UK, has been found to be effective in before/after and qualitative studies, but lacks a randomised controlled trial (RCT) evidence base. Methods/Design A multi-centre, investigator blind, randomised controlled trial of the FLNP with a target sample of 288 south Wales families who have a child aged 2-4 yrs living in or near to Flying Start/Sure Start areas. Changes in parenting, parent child relations and parent and child wellbeing are assessed with validated measures immediately and at 6 months post intervention. Economic components include cost consequences and cost utility analyses based on parental ranking of states of quality of life. Attendance and completion rates and fidelity to the FLNP course delivery are assessed. A nested qualitative study will assess reasons for participation and non-participation and the perceived value of the programme to families. By the end of May 2010, 287 families have been recruited into the trial across four areas of south Wales. Recruitment has not met the planned timescales with barriers including professional anxiety about families entering the control arm of the trial, family concern about video and audio recording, programme facilitator concern about the recording of FLNP sessions for fidelity purposes and delays due to the new UK research governance procedures. Discussion Whilst there are strong theoretical arguments to support universal provision of parenting programmes, few universal programmes have been subjected to randomised controlled trials. In this paper we describe a RCT protocol with quantitative and qualitative outcome measures and an economic evaluation designed to provide clear evidence with regard to effectiveness and costs. We describe challenges implementing the protocol and how we are addressing these
