What do peer support workers do? A job description.

BackgroundThe extant literature suggests that poorly defined job roles make it difficult for peer support workers to be successful, and hinder their integration into multi-disciplinary workplace teams. This article uses data gathered as part of a participatory evaluation of a peer support program at a psychiatric tertiary care facility to specify the work that peers do.MethodsData were gathered through interviews, focus groups, and activity logs and were analyzed using a modified grounded theory approach.ResultsPeers engage in direct work with clients and in indirect work that supports their work with clients. The main types of direct work are advocacy, connecting to resources, experiential sharing, building community, relationship building, group facilitation, skill building/mentoring/goal setting, and socialization/self-esteem building. The main types of indirect work are group planning and development, administration, team communication, supervision/training, receiving support, education/awareness building, and information gathering and verification. In addition, peers also do work aimed at building relationships with staff and work aimed at legitimizing the peer role. Experience, approach, presence, role modeling, collaboration, challenge, and compromise can be seen as the tangible enactments of peers' philosophy of work.ConclusionsCandidates for positions as peer support workers require more than experience with mental health and/or addiction problems. The job description provided in this article may not be appropriate for all settings, but it will contribute to a better understanding of the peer support worker position, the skills required, and the types of expectations that could define successful fulfillment of the role

Downwash-Aware Trajectory Planning for Large Quadrotor Teams

We describe a method for formation-change trajectory planning for large quadrotor teams in obstacle-rich environments. Our method decomposes the planning problem into two stages: a discrete planner operating on a graph representation of the workspace, and a continuous refinement that converts the non-smooth graph plan into a set of C^k-continuous trajectories, locally optimizing an integral-squared-derivative cost. We account for the downwash effect, allowing safe flight in dense formations. We demonstrate the computational efficiency in simulation with up to 200 robots and the physical plausibility with an experiment with 32 nano-quadrotors. Our approach can compute safe and smooth trajectories for hundreds of quadrotors in dense environments with obstacles in a few minutes.Comment: 8 page

A lattice determination of QCD field strength correlators

We study field strength correlators in presence of a static quark-antiquark pair by use of lattice methods. The lattice data have been acquired recently in the context of a determination of relativistic corrections to the static interquark potential. We extract independent estimates of the form factors of two point correlation functions and investigate the effect of higher order correlators. Our results confirm the dominance of the two point correlators in the regions of intermediate and large quark separations, and are compatible with correlation length values obtained from different approaches.Comment: 13 pages LaTeX (elsart.sty) with 5 eps figures, typos corrected, Figure 2 replaced and some changes in results section for enhanced clarity of presentatio

Forest management intensity affects aquatic communities in artificial tree holes

Forest management could potentially affect organisms in all forest habitats. However, aquatic communities in water-filled tree-holes may be especially sensitive because of small population sizes, the risk of drought and potential dispersal limitation. We set up artificial tree holes in forest stands subject to different management intensities in two regions in Germany and assessed the influence of local environmental properties (tree-hole opening type, tree diameter, water volume and water temperature) as well as regional drivers (forest management intensity, tree-hole density) on tree-hole insect communities (not considering other organisms such as nematodes or rotifers), detritus content, oxygen and nutrient concentrations. In addition, we compared data from artificial tree holes with data from natural tree holes in the same area to evaluate the methodological approach of using tree-hole analogues. We found that forest management had strong effects on communities in artificial tree holes in both regions and across the season. Abundance and species richness declined, community composition shifted and detritus content declined with increasing forest management intensity. Environmental variables, such as tree-hole density and tree diameter partly explained these changes. However, dispersal limitation, indicated by effects of tree-hole density, generally showed rather weak impacts on communities. Artificial tree holes had higher water temperatures (on average 2° C higher) and oxygen concentrations (on average 25% higher) than natural tree holes. The abundance of organisms was higher but species richness was lower in artificial tree holes. Community composition differed between artificial and natural tree holes. Negative management effects were detectable in both tree-hole systems, despite their abiotic and biotic differences. Our results indicate that forest management has substantial and pervasive effects on tree-hole communities and may alter their structure and functioning. We furthermore conclude that artificial tree-hole analogues represent a useful experimental alternative to test effects of changes in forest management on natural communities.Fil: Petermann, Jana S..

Analisis Kualitas Pelayanan Akta Kelahiran Di Dinas Kependudukan Dan Pencatatan Sipil Kota Semarang

Ownership of birth certificate is very important since it is a form of someone\u27s identity which will be used as the basis to obtain other public services. Based on the data from Department of Population and Civil Registration of Semarang in 2004-2014, there are still 127.369 childerns have not had birth. Thus, this research aims to analyze the quality of service of the birth certificate and to know factors influence it in Department of Population and Civil Registration of Semarang. The research method used was descriptive qualitative while the election informants technique was purposive sampling. The researcher collected the data through interviews, observation, and study documentation. The result of this research indicates that, there are three of five quality dimensions service that are not qualified. Those are tangible, reliability, and responsiveness. It is seen from the quantity of infrastructure that is still inadequate and less carefully preserved, the procedure of birth certificate that is not socialized well, the customer service that does not serve well, the lack of awareness of the birth certificate applicants for their rights, and there is no customer care available yet. Therefore, Department of Population and Civil Registration of Semarang has to give more good response to all the service birth certificate with responsive, reliable, right, and accurate. Also, the applicants should be more active and aware of the importance of the birth certificate. They could also take part in the service of birth certificate in Department of Population and Civil Registration of Semarang

Zooming in on spatial scaling: Preschool children and adults use mental transformations to scale spaces

Spatial scaling is an important prerequisite for many spatial tasks and involves an understanding of how distances in different-sized spaces correspond. Previous studies have found evidence for such an understanding in preschoolers; however, the mental processes involved remain unclear. The present study investigated whether children and adults use mental transformations to scale distances in space. Adults and 4- and 5-year-old children (N = 60) were asked to use maps to locate target objects in a larger referent space on a touchscreen. The size of the referent space was held constant, but the sizes of the maps were varied systematically, resulting in seven scaling factors. A linear increase in response times and errors with increasing scaling factor suggested that participants of every age group mentally transformed the size of the map to compare it to the referent, providing evidence for an analog imagery strategy in children’s and adults’ spatial scaling

Using mental transformation strategies for spatial scaling: Evidence from a discrimination task

Spatial scaling, or an understanding of how distances in different-sized spaces relate to each other, is fundamental for many spatial tasks and relevant for success in numerous professions. Previous research has suggested that adults use mental transformation strategies to mentally scale spatial input, as indicated by linear increases in response times and accuracies with larger scaling magnitudes. However, prior research has not accounted for possible difficulties in encoding spatial information within smaller spaces. Thus, the present study used a discrimination task in which we systematically pitted absolute size of the spaces against scaling magnitude. Adults (N = 48) were presented with 2 pictures, side-by-side on a computer display, each of which contained a target. Adults were asked to decide whether the targets were in the same position or not, by pressing the respective computer key. In the constant-large condition, the constant space was kept large, whereas the size of the other space was variable and smaller. In the constant-small condition, the constant space was small, whereas the size of the other space was variable and larger. Irrespective of condition, adults’ discrimination performance (d- primes) and response times were linear functions of scaling magnitude, supporting the notion that analog imagery strategies are used in spatial scaling

Using a touch screen paradigm to assess the development of mental rotation between 3½ and 5½ years of age

Mental rotation is an important spatial skill. However, there is controversy concerning its early development and susceptibility to intervention. In the present study, we assessed individual differences in the mental rotation abilities of children between 3½ and 5½ years of age, using a touch screen paradigm to simplify task demands. A figure or its mirror image was presented in 8 different orientations, and children indicated in which of two holes the figure would fit by touching one of the holes on the screen. Task instructions were varied in three conditions, giving the children the opportunity to gather manual or observational experience with rotations of different stimuli, or giving no additional experience. Children’s error rates and response times increased linearly with increasing angular disparity between the figure and the hole by the age of 5 years, but 4-year-olds were found to respond at chance for all angular disparities, despite the use of a touch screen paradigm. Both manual and observational experience increased the response accuracy of 5-year-olds, especially for children already performing well. However, there was no effect on 4-year-olds. Results point to an emerging readiness to use mental rotation and profit from observational and manual experience at age 5
