Understanding how student teachers undertake their group work may provide solid foundation for developing essential skills required for the 21st Century teachers, and subsequently help improve group-based assessment in higher education. However, social loafing has been found to interfere with this assessment mode. This article reports on undergraduate student teachers’ reactions to social loafers when working on group assignments as part of their continuous assessment. It focuses on how they go about doing their group work and react to the social loafers. The data were collected using face-to-face semi-structured interviews from 18 purposefully and conveniently selected participants. The findings have indicated procedures that students observe in doing their group assignments such as formulation of own group norms and rules, and holding of meetings for the work being determined by the nature of the assignments, and their submission deadlines. Additionally, it has been found that group members employ humanitarian, punitive and threatening approaches as they react to social loafers. The article concludes that proper planning for students’ group assignments is important and; both instructors and students should play their roles accordingly to overcome the problem of social loafing when the use of group-based assessments is indispensable within higher education contexts.

Abstract The paper discusses a new approach to the processing of verbal assessments, which express the opinions of experts on many criteria. The algorithm for verbal analysis of multi-feature objects expert assessments is proposed for identifying subgroups of experts with agreed opinions. It is proposed to use the multiplicity indices of multisets to calculate the coefficient of consistency. It is also proposed to use jointly the coefficients of consistency values to assess the consistency of the experts subgroups on one feature, and strive for the total maximization of the coefficients of consistency for all features. The complexity of the proposed algorithm is estimated. The results of calculations for the problem of choosing the best science-intensive technology are presented.

Group-based assessments used in the Bachelor of Nursing Science (clinical) Honours programme at a public university in Namibia are usually in the form of assignments and projects. Completing tasks in groups helps students to develop important skills like critical thinking and debating. In addition, it prepares them to work in the health-care environment where collaboration with others is required. That said, nursing students lack cooperation during the process of completing their group assignments or projects. A classroom-based research was conducted using action research as the design. The objectives were to: explore what is causing lack of cooperation during group-based assessment as perceived by nursing students, and to propose, implement and evaluate measures to improve cooperation during group-based assessment task completion. Themes that emerged as factors contributing to a lack of cooperation are: student motivation, student personal characteristics, lack of planning to approach the allocated task, student learning approaches, communication-related issues, and group composition and allocation procedures. The proposed measures of students to ensure cooperation are: selection of group leaders, determining lecturer roles in facilitating group assessment, improving communication, and involvement of students in the allocation procedures of group members.All suggestions were successfully implemented. Evaluation of measures to ensure cooperation revealed that students appreciated the group-based approach strategy given its very positive impact on their learning.

This paper explores the effect of applying gamification and flipped classroom approaches through our group-based assessment game, the CrossQuestion, in the course of IT in Business. The course teaches basic IT fundamentals and their application in different functional areas of business and management. In Spring 2020-21, we delivered this course through Moodle platform, integrated with the Zoom video communication tool, to introduce the CrossQuestion game as supplemental resources to engage students. We conducted measurements using the Instructional Materials Motivation Survey scales to verify the game's learning effect. We divided students into an experimental group (85 students who played the CrossQuestion game through gamified flipped classroom session–Spring 2020-21) and a control group (60 students who previously underwent lecture-based instructions and individualized formal assessments–Spring 2019-20). The analysis of students’ grades confirms improvement by applying gamified flipped classroom group-based assessments in the learning process. The students’ questionnaire also confirms that group-based assessments can improve students’ motivation. We developed a game system that was attractive to the students, implying that it can be an effective instructional and recreational material to boost morale, increase collaboration, enhance engagement and socialization opportunities, especially during this challenging pandemic.

The study focused to determine the competency-based learning assessment and the scientific literacy knowledge skills of the Grade 9 students of Silangang Malicboy National High School. There were 187 Grade 9 students in the said school. Three sections out of five sections of Grade 9 were tapped as respondents of the study. Each group consisted of 40 students. The first group was exposed to the proficiency-based while the second group used mastery-based and the third group the outcome-based. The researcher made lesson plan wherein the different competencybased learning assessments were attached. This assessment tool was used by the different groups to develop and enhance their scientific literacy knowledge skills. The lesson plan with 40 items pre and post assessments and the checklist questionnaires were validated by the master teachers, research adviser and panelists. The study employed the experimental design using the pretest – posttest. The performance of Grade 9 students in the pre-assessment as to their scientific literacy knowledge skills such as critical thinking and decision-making fell under “Approaching Proficiency” level while in the investigative skills and problem solving, most students were under the “Beginning” level. On the other hand, when the students used the competencybased learning assessment, their performance improved and developed which was supported by the result of their post assessment under the “Advanced” level. Result also indicates that there was a significant difference in the performance of the students in pre and post assessments when they were exposed to the competency-based learning assessment as to critical thinking, investigative skills, problem solving and decision-making. This reveals that using the said assessment tool, it can enhance the scientific literacy knowledge skills of the students.

This article is based on research which was undertaken to determine the effectiveness of two types of group work in the assessment of acutely disturbed adult psychiatric patients. The effectiveness of groups for assessment was determined by comparing the occupational therapy assessments of patients after one group session with those assessments made by other professional team members over the period of one week. The study was carried out at two acute psychiatric units in Johannesburg. Thirty patients were assessed by the author and by four members of the team. The five assessments were compared for each patient by statistical analysis. The results indicate that there is no significant difference between the five assessments or between the assessments undertaken in the art groups and those undertaken in the discussion groups. The short-term assessments of patients during these two types of group work is therefore effective.

Abstract Background and study aims Novice endoscopists are inaccurate in self-assessment of procedures. One means of improving self-assessment accuracy is through video-based feedback. We aimed to determine the comparative effectiveness of three video-based interventions on novice endoscopists’ self-assessment accuracy of endoscopic competence. Materials and methods Novice endoscopists (performed < 20 previous procedures) were recruited. Participants completed a simulated esophagogastroduodenoscopy (EGD) on a virtual reality simulator. They were then randomized to one of three groups: self-video review (SVR), which involved watching a recorded video of their own performance; benchmark review (BVR), which involved watching a video of a simulated EGD completed by an expert; and self- and benchmark video (SBVR), which involved both videos. Participants then completed two additional simulated EGD cases. Self-assessments were conducted immediately after the first procedure, after the video intervention and after the additional two procedures. External assessments were conducted by two experienced endoscopists, who were blinded to participant identity and group assignment through video recordings. External and self-assessments were completed using the global rating scale component of the Gastrointestinal Endoscopy Competency Assessment Tool (GiECAT GRS). Results Fifty-one participants completed the study. The BVR group had significantly improved self-assessment accuracy in the short-term, compared to the SBVR group (P = .005). The SBVR group demonstrated significantly improved self-assessment accuracy over time (P = .016). There were no significant effects of group or of time for the SVR group. Conclusions Video-based interventions, particularly combined use of self- and benchmark video review, can improve accuracy of self-assessment of endoscopic competence among novices.

There is a soaring demand for work-ready graduates who can quickly adapt to an ever-challenging work environment. Group-based assessments have been widely recommended as a means to develop the skills required for the world of work. However, group-based assessments are perceived as challenging for both students and educators. This systematic literature review (SLR), based on the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA), focuses on analyzing and synthesizing the existing literature on group-based assessments. A four-step approach was undertaken in order to conduct this research. The SLR identified 71 relevant articles, analyzed using thematic analysis with the aid of NVivo software. An open coding approach was adopted to generate codes. The validity of the SLR process and the reliability of the research tool were maintained through the use of trustworthiness. The findings identified dominant themes such as self- and peer evaluations, training students for group work assessments, group formation, group size, and the role of academics and technology in facilitating group processes. The outcomes of this review contribute significantly to the design and administration of group-based assessments in higher education by providing academics with practical guidelines to effectively facilitate group-based assessments which fit the purpose.

Technology adoption in classrooms has impacted the way educational practitioners conduct assessments. Online quizzes are preferred compared to paper-pencil based tests. However, very few information that explains the contribution of online assessment towards holistic attainment of students in English. The present study aimed at examining the effects of online assessments on students’ performance. This research employed a quasi-experimental study to evaluate the role of interactive online assessments toward students’ performance in English. Eighty-six undergraduate students in TESL participated in this study; 53 were randomly assigned to the online group while 33 were assigned to the control group. The research computed t-tests to compare the performance of both groups on five different assessments. The results revealed that the online assessment group performed better on four assessments tested—listening and reading skills. The control group performed significantly higher on the assessment that involved presentation (evaluated speaking skill). These findings indicate that online assessments enhance students’ mastery of listening, reading, and writing skill but rather not so much influence on verbal skills. This research implies that educational practitioners should not entirely rely on interactive online platforms. To incorporate the blended-learning approach, classroom activities must consist of a combination of online and offline strategies.

[EN] The main objectives of this research are the following. First, to analyse the models and methods in Decision Support Systems (DSS) for forest management, taking into account the important features which allow forestry related problems to be categorized. Second, to define strategic criteria for the sustainable management of Mediterranean forests, as well as to elicit and aggregate the stakeholders' preferences. Third, to propose a robust methodology to implement collaborative management focused on ESS and to develop indicators for the main functions of ESS.
The methodology is based on a workshop and surveys to elicit the decision makers', experts' and other stakeholders' preferences. Several techniques were then used to aggregate individual judgements and determine social preferences, in particular, Analytic Hierarchy Process (AHP) and Goal Programming (GP). In addition, a PROMETHEE based method has been developed to provide indicators of the ESS, classified into provisioning, maintenance and direct to citizens services.
The analysis of DSS for forest management has shown that the best choice of approach to solve a given problem depend on its nature, which can be characterized by the temporal scale, spatial context, spatial scale, number of decision makers or stakeholders, objectives and finally goods and services involved.
A decision hierarchy for strategic management of Valencian forests has been developed by involving experts during the design phase. This was later validated in consultation with the stakeholders in a workshop and provides the base from which to obtain the social preferences. The results show greater importance for environmental and social criteria and lesser relevance for economic criteria, valid for both public and private Mediterranean forests. This result is the same regardless of which preference aggregation technique was used and takes into account the preferences of the majority of the stakeholders and also the minority opinions furthest from the consensus. New products and services such as rural tourism, renewable energies, landscape, hydrological regulation and erosion control, biodiversity and climate change mitigation are relevant.
This research also proposes a robust methodology to implement collaborative management focused on ESS provided by protected areas and aggregated indicators for their main functions. Decision makers, technical staff and other stakeholders are included in the process from the beginning, by identifying ESS and eliciting preferences using the AHP method. Qualitative and quantitative data are then integrated into a PROMETHEE based method in order to obtain indicators for provisioning, maintenance and direct to citizens services. This methodology, which has been applied in a forest natural park, provides a tool for exploiting available technical and social data in a continuous process, as well as graphical results, which are easy to understand. This approach also overcomes the difficulties found in prioritising management objectives in a multiple criteria context with limited resources and facilitates consensus between all of the people involved. The new indicators define an innovative approach to assessing the ESS from the supply perspective and provide basic information to help establish payment systems for environmental services and compensation for natural disasters.[ES] Los principales objetivos de esta investigación son los siguientes. En primer lugar, analizar los modelos y los métodos de los sistemas de ayuda a la toma de decisiones para gestión forestal, teniendo en cuenta las características relevantes que permiten clasificar los problemas forestales. En segundo lugar, definir los criterios estratégicos para la gestión forestal sostenible del bosque mediterráneo, así como obtener y agregar las preferencias de los decisores y otras partes interesadas. En tercer lugar, proponer una metodología robusta para implementar una gestión colaborativa centrada en los servicios del ecosistema y desarrollar indicadores para las principales funciones de estos servicios. La metodología se fundamenta en una jornada de trabajo con decisores, expertos y otros grupos de personas interesadas, así como en encuestas a todos ellos. Después se han utilizado varias técnicas para agregar las preferencias individuales y determinar las preferencias de los distintos grupos sociales, en particular el proceso analítico jerárquico y la programación por metas. Adicionalmente, se ha desarrollado un método basado en PROMETHEE que permite obtener indicadores de los servicios del ecosistema, clasificados en servicios de producción, mantenimiento y directos a los ciudadanos. El análisis de los sistemas de ayuda a la toma de decisiones para gestión forestal ha puesto de manifiesto que los mejores enfoques para resolver los problemas forestales dependen de su naturaleza, caracterizada por la escala temporal, el contexto espacial, la escala espacial, el número de decisores o personas interesadas, el número de objetivos y por último los bienes y servicios involucrados. Se ha desarrollado una jerarquía de decisión para la gestión estratégica de los bosques valencianos involucrando a expertos en la fase de diseño. Este modelo fue validado posteriormente por las partes interesadas en una jornada organizada con esta finalidad y ha sido la base para obtener las preferencias sociales. Los resultados ponen de manifiesto la mayor importancia de los criterios medioambientales y sociales y la menor relevancia de los económicos, tanto para el monte mediterráneo público como privado. Este resultado es independiente del método de agregación utilizado y tiene en cuenta tanto las preferencias de la mayoría como de la minoría más alejada del consenso. Son relevantes los nuevos productos y servicios tales como el turismo rural, las energías renovables, el paisaje, la regulación hidrológica y el control de la erosión, la biodiversidad y la mitigación del cambio climático. Esta investigación también propone una metodología robusta para implementar una gestión colaborativa centrada en los servicios del ecosistema que proporcionan las áreas protegidas e indicadores agregados para sus principales funciones. Los responsables de las decisiones, el personal técnico y otras personas interesadas han participado desde el inicio del proceso, identificando los servicios del ecosistema y proporcionado sus preferencias mediante la técnica del proceso analítico jerárquico. Después se integran los datos cualitativos y cuantitativos en un método basado en PROMETHEE con la finalidad de obtener indicadores para los servicios de producción, mantenimiento y directos a los ciudadanos. Esta metodología, que se ha aplicado en un parque natural, facilita la explotación de los datos técnicos y sociales en un proceso continuo y proporciona resultados gráficos muy fáciles de entender. Este enfoque también permite superar las dificultades que surgen al priorizar los objetivos de gestión en un contexto multicriterio con recursos limitados y facilita el consenso entre todas las personas involucradas. Los nuevos indicadores representan un enfoque innovador para la valoración de los servicios del ecosistema desde el punto de vista de la oferta y proporcionan información básica para establecer sistemas de pagos por
[CAT] Els principals objectius d'aquesta recerca són els següents. En primer lloc, analitzar els models i els mètodes dels sistemes d'ajuda a la presa de decisions per a gestió forestal, tenint en compte les característiques rellevants que permeten classificar els problemes forestals. En segon lloc, definir els criteris estratègics per a la gestió forestal sostenible del bosc mediterrani, com també obtenir i agregar les preferències dels decisors i altres parts interessades. En tercer lloc, proposar una metodologia robusta per a implementar una gestió col·laborativa centrada en els serveis de l'ecosistema i desenvolupar indicadors per a les principals funcions d'aquests serveis. La metodologia es fonamenta en una jornada de treball amb decisors, experts i altres grups de persones interessades, i també en enquestes a tots ells. Després s'han utilitzat diverses tècniques per a afegir-hi les preferències individuals i determinar les preferències dels diferents grups socials, en particular el procés analític jeràrquic i la programació per metes. Addicionalment, s'ha desenvolupat un mètode basat en PROMETHEE que permet obtenir indicadors dels serveis de l'ecosistema, classificats en serveis de producció, manteniment i directes als ciutadans. L'anàlisi dels sistemes d'ajuda a la presa de decisions per a la gestió forestal ha posat de manifest que els millors enfocaments per a resoldre els problemes forestals depenen de la naturalesa d'aquests problemes, caracteritzada per l'escala temporal, el context espacial, l'escala espacial, el nombre de decisors o persones interessades, el nombre d'objectius i, finalment, els béns i serveis involucrats. S'ha desenvolupat una jerarquia de decisió per a la gestió estratègica dels boscos valencians involucrant experts en la fase de disseny. Aquest model ha sigut validat posteriorment per les parts interessades en una jornada organitzada amb aquesta finalitat i ha sigut la base per a obtenir les preferències socials. Els resultats posen de manifest la major importància dels criteris mediambientals i socials i la menor rellevància dels econòmics, tant per a la muntanya mediterrània pública com privada. Aquest resultat és independent del mètode d'agregació utilitzat i té en compte tant les preferències de la majoria com de la minoria més allunyada del consens. Són rellevants els nous productes i serveis, com ara el turisme rural, les energies renovables, el paisatge, la regulació hidrològica i el control de l'erosió, la biodiversitat i la mitigació del canvi climàtic. Aquesta recerca també proposa una metodologia robusta per a implementar una gestió col·laborativa centrada en els serveis de l'ecosistema que proporcionen les àrees protegides i indicadors agregats per a les seues funcions principals. Els responsables de les decisions, el personal tècnic i altres persones interessades hi han participat des de l'inici del procés, identificant els serveis de l'ecosistema i proporcionant les seues preferències mitjançant la tècnica del procés analític jeràrquic. Després s'integren les dades qualitatives i quantitatives en un mètode basat en PROMETHEE amb la finalitat d'obtenir indicadors per als serveis de producció, manteniment i directes als ciutadans. Aquesta metodologia, que s'ha aplicat en un parc natural, facilita l'explotació de les dades tècniques i socials en un procés continu i proporciona resultats gràfics molt fàcils d'entendre. Aquest enfocament també permet superar les dificultats que sorgeixen a l'hora de prioritzar els objectius de gestió en un context multicriteri amb recursos limitats i facilita el consens entre totes les persones involucrades. Els nous indicadors representen un enfocament innovador per a la valoració dels serveis de l'ecosistema des del punt de vista de l'oferta i proporcionen informació bàsica per a establir sistemes de pagaments per serveis ambientals i compensacions per desastres naturals.

Texto completoResumen
The overarching aim of the present thesis is to gain knowledge about how Rwandan university students understand and practice group-based learning. Specifically, this research takes a social constructivist perspective when examining how second year students within the area of Modern Languages reflect on collaborative writing and peer assessment as means to promote academic writing and active learning. Four studies make up this research. Thus, Study I examines how students carry out self-directed group work in writing. Study II investigates how instructor-guided writing groups can help promote students’ collaborative learning. Study III explores in what ways process writing as instruction method can help develop students’ academic writing abilities and Study IV focuses on how students experience peer assessment and peer feedback on group writing. The data, which are qualitative, were collected by means of interviews carried out with groups of students. The findings show that students perceive and conduct group-based learning in different ways, which can impact the quality of their learning. Also, based on initial support and guidance from the course instructor, most students acknowledged having been able to take stock of their common writing abilities and understand in what ways peer assessment and peer feedback can help them improve, and thus enrich their learning. A few students considered the common writing process time consuming though. In conclusion, some strategies are suggested to further improve group-based learning.Det övergripande syftet med denna avhandling är att söka kunskap om hur universitetsstudenter i Rwanda förstår och praktiserar gruppbaserat lärande. Teoretiskt utgår den från ett socialkonstruktivistiskt perspektiv med särskilt fokus riktat mot hur studenter inom ämnesområdet moderna språk reflekterar över kollaborativt skrivande och inbördes bedömning som ett sätt att främja akademiskt skrivande och aktivt lärande. Avhandlingen består av fyra studier. I studie I undersöks studenters reflektioner över hur deras självstyrda skrivande i grupp genomförs. Studie II belyser lärarens roll i lärarlett skrivande i grupp och hur det kan påverka studenters kollaborativa lärande. I studie III studeras på vilket sätt metoder som synliggör skrivprocessen kan stödja studenters utveckling inom akademiskt skrivande. Studie IV fokuserar hur studenter erfar inbördes bedömning av skrivande i grupp. Data består av kvalitativa intervjuer genomförda med grupper av studenter under deras andra högskoleår Resultaten visar att studenterna uppfattar och genomför gruppbaserat lärande på olika sätt vilket kan påverka kvaliteten på deras lärande. Givet ett initialt stöd och vägledning från läraren som grund, bekräftade de flesta studenterna att de i grupparbetet kunde utnyttja sin gemensamma skrivförmåga och förstå på vilket sätt inbördes utvärdering kan hjälpa dem att förbättra sitt skrivande och därmed berika deras lärande. Vissa ansåg dock att den gemensamma skrivprocessen var tidsödande. Avslutningsvis föreslås strategier som kan användas för att ytterligare förbättra ett gruppbaserat lärande.

ABSTRACT Predicting On-the-Job Teacher Success Based on a Group Assessment Procedure Used for Admission to Teacher Education by LaVaun Gene Faulk, Doctor of Education Utah State University, 2008 Major Professor: Deborah Byrnes, Ph.D. Department: Elementary Education Students who have graduated in Elementary Education at Utah State University, since 1997 when the group assessment interview procedure was adopted, and have been employed as teachers for at least two years were contacted. Students were located with the help of the Utah State Office of Education (USOE) and the Office of Teacher Education, Graduation, and Educator Licensing at USU. Permission to interview each teacher’s supervisor was obtained from each study participant. Principals were contacted and interview dates set. A self-anchoring interview was conducted to provide quantitative data on the success of each teacher. This new data was then used to compare each participant’s success as seen by supervisors to existing data already on record at USU. Specifically, principal interview data were compared to the participant’s student teaching scores, prior academic achievement data (grade point average and American College Test scores), and ratings the teacher received on the group assessment interviews when applying to the elementary education teacher training program at USU.

This action research study focuses on students' perceptions of group work and its assessment. The research records a four-year study involving 729 first, second and third year undergraduate students. Having started with an exploration into students' perceptions of group work, it identified social loafing as students' key concern, explored ways to alleviate the problem, presented students with a range of options and ended with an examination of students' perceptions of the formative and summative peer assessment process they chose to implement. Research was undertaken using a mixed model design referred to as "intramethod mixing" by Johnson and Turner (2003, p. 298). This involved the concurrent and sequential use of a single method (questionnaires) that included both qualitative and quantitative components. As a result of the research a pragmatic and evidence-based approach to the assessment of group work on undergraduate courses is suggested. Also six overarching themes emerged: • Group work as a social activity that can foster the development of a community of practice. • Students' lack of knowledge of how to work in groups and need for relevant training. • Students' dislike of receiving one group mark for group work. • Tension between fairness, transparency and validity when peers summatively assess peers' contribution to group work. • The role of formative peer assessment (which should remain anonymous) in assessment as learning. • Tension between the delegation of control over the assessment process and the tutor's role as assessor.

Texto completoResumen
Early identification practices in assessment are crucial to preventing academic failure as well as identifying students at-risk for later learning disabilities. The PAM Early Numeracy Screening is a set of subscales designed to measure early numeracy in kindergarten students in a group setting. Given that the existing early numeracy measures are individually administered, the purpose of the current study was to explore the psychometric properties of the PAM Early Numeracy Screening. Correlational analysis was the primary research design used to investigate the evidence of reliability, criterion-related validity, and construct validity of the PAM Early Numeracy Screening. Criterion measures included the KeyMath-3 Diagnostic Assessment, Metropolitan Achievement Tests, Eighth Edition, Early Math Measures Study Teacher Rating of Students’ Math Proficiency, and the Early Numeracy Indicators. The sample consisted of 97 kindergarten students from a school district in the Greater New Orleans Metropolitan Area. Results support the PAM Early Numeracy Screening as a promising group administered measure of early numeracy in kindergarten. Implications for future research include investigating the internal structure of the subscales and exploring evidence of predictive validity of the subscales, specifically the Quantity Discrimination subscale to independently predict later math achievement.

This thesis examines pupils’ justice conceptions regarding educational assessment. Due to the context-dependency of norms and values as well as of assessment, the study compares the justice conceptions of pupils in two different’socio-educational’ contexts: Sweden and Germany. The main interest of the study is to understand and to reconstruct pupils’ own relevance structures and what just assessment means from a pupils’ point of view. Here, the study aims to reach beyond the level of mere description by providing theoretical conceptualisations of pupils’ justice conceptions regarding assessment. Thus, the study´s methodological foundation is characterised by a combination of a context-sensitive comparative approach on the one hand, and on the other hand a pragmatist Grounded Theory approach. Data were mainly generated through focus group interviews with pupils attending the last year of the lower secondary level in the Swedish comprehensive school as well as in different school types in the German school system. In total, the sample consists of 95 pupils, who were interviewed in 21 focus group interviews. In addition, other sources of data were included, such as regulations and guidelines that supported a context-sensitive analysis of pupils’ conceptions. The theoretical conceptualisation that explains pupils’ justice conceptions is ‘meta-assessment’. ‘Meta-assessment’ refers to pupils’ evaluation of the assessment they experience in terms of justice and represents the shared, abductively derived and overlying analytical category regarding pupils’ conceptions. Pupils’ ‘meta-assessment’ is based on normative justice conceptions as well as on justice conceptions that are related to pupils’ situation and context-bound experiences with assessment. The first ones are about the ethico-moral character of pupils’ justice conceptions. The second shed light on the contextual conditions and consequences of the logics and practices underlying educational assessment as experienced by pupils on an everyday basis. This implies that just assessment from a pupils’ perspective needs to be understood in its wider contextual embedment; and in relation to teaching and learning in order to understand the complex interrelations of what just assessment ‘is’, and ‘should be’ from the perspective of those, who are mainly affected by it.

Texto completoResumen
Ovarian cancer (OC) is the fifth most common cancer among women and has the highest mortality of any cancer of the female reproductive system. The majority (61%) of OC cases are diagnosed at a distant stage. Because diagnoses occur most commonly at a late-stage and prognosis for advanced disease is poor, research focusing on the development of effective OC screening methods to facilitate early detection in high-risk, asymptomatic women is fundamental in reducing OC-specific mortality. Presently, there is no screening modality proven efficacious in reducing OC-mortality. However, transvaginal ultrasonography (TVS) has shown value in early detection of OC. TVS presents with the possibility of false positive results which occur when a women receives an abnormal TVS screening test result that is deemed benign following repeat testing (about 7% of the time). The purpose of this dissertation was to evaluate the impact of false positive TVS screening test results on a variety of psychological and behavioral outcomes using mixed and trajectory statistical modeling. The three specific aims of this dissertation were to 1) compare psychological and behavioral outcomes between women receiving normal and false positive results, 2) identify characteristics of women receiving false positive results associated with increased OC-specific distress and 3) characterize distress trajectories following receipt of false positive results.
Analyses included a subset of women participating in an experimental study conducted through the University of Kentucky Ovarian Cancer Screening Program. 750 women completed longitudinal assessments: 375 false positive and 375 normal results. Mixed and group-based trajectory modeling were used to evaluate the specific aims.
Results suggest women receiving false positive TVS result experience increased OC-specific distress compared to women receiving normal results. Among those receiving false positives, less education, no history of an abnormal screening test result, less optimism and more social constraint were associated with increased OC-specific distress. Family history was associated with increased distress among women with monitoring informational coping styles. Three distinct trajectories characterize the trajectory of distress over a four-month study period. Although decreasing over time, a notable proportion of women experience sustained high levels of OC-specific distress.

Texto completoResumen
Bedömning av kvaliteten är en av de viktigaste processerna som en lärare utför varje arbetsdag för att kunna relatera elevernas prestationer mot ett kulturellt och individuellt anpassat betygssystem. Med ambitionen att främja jämställdhet och reliabilitet av bedömningar tillhandahåller Skolverket bedömningskrav och kriterier för att skilja olika grader av kvalitet (Selghed 2011). Dessa kriterier förefaller emellertid ibland otydliga och inte lämpliga för att särskilja mellan kvalitativa nivåer, särskilt på högre nivåer, vilka därför kan uppfattas som delvis överlappande. Som följd finns det mycket utrymme för tolkning av den enskilda läraren när det slutliga bedömningssystemet konstrueras (Schreiber et al., 2012, Selghed 2011). En alternativ bedömningsmetod som är rekommenderad av t.ex. Hattie (2012), är den mindre komplexa SOLO-taxonomin vilken idag används i de högre utbildnings miljöer.För att uppskatta överlappningen mellan resultat som härrör från olika bedömningsmetoder analyserar denna studie kvalitetsnivåer av en skrivuppgift av andraårs-gymnasieelever med hjälp av det läroplanbaserade betygssystemet och SOLO-taxonomin. Med hjälp av principiell komponentanalys (PCA) och korrelationsanalys kunde man dra slutsatsen att de olika bedömningsmetoderna är lämpliga för att skilja högre från lägre komplexitet eller kvalitetsnivåer. Men SOLO-taxonomin kunde inte tydligt skilja de mer sofistikerade skillnaderna mellan högre betygsnivå A och B.Dessutom undersökte denna studie om en noggrant genomförd konstruktivistisk undervisningsdesign oundvikligen resulterar i högkvalitativa skriftliga arbeten. Detta analyserades med hjälp av PCA och korrelationsanalys av relationen mellan deltagarnas kunskapssyn och bedömningsresultatet. Inom detta sammanhang kunde det dras slutsatsen att (I) en mer sofistikerad syn på naturen av kunskap och kunskap och (II) heterogeniteten hos en studentgrupp med avseende på kunskapssynen verkar vara kopplad till högre kvalitativa prestationer. Bevis för en korrelation mellan elevernas individuella kunskapssyn och de valda inlärningsmetoderna diskuteras inom ramen för en generell lämplighet av konstruktivistiska undervisningsmetoder.

Texto completoResumen
Forecasting eruptions using volcano seismology is a subject that affects the lives and property of millions of people around the world. However, there is still much to learn about the inner workings of volcanoes and how this relates to the chance of eruption. This dissertation attempts to increase the breadth of knowledge aimed at helping to understand when a volcano is likely to erupt and how large that eruption might be. Chapters 2 and 3 focus on a technique that uses changes in the local stress field beneath a volcano to determine the source of these changes and help forecast eruptions, while Chapter 4 focuses on a technique that shows great potential to be used to image magma chambers beneath volcanoes by using receiver functions.
In Chapters 2 and 3 the source mechanisms of shallow volcano-tectonic earthquakes recorded at Mount St. Helens are investigated by calculating hypocenter locations and fault plane solutions (FPS) for shallow earthquakes recorded during two eruptive periods (1981-1986 and 2004-2008) and two non-eruptive periods (1987-2004 and 2008-2011). FPS show a mixture of normal, reverse, and strike-slip faulting during all periods, with a sharp increase in strike-slip faulting observed in 1987-1997 and an increase in normal faulting between 1998 and 2004 and again on September 25-29, 2004. FPS P-axis orientations (a proxy for ó1) show a ~90° rotation with respect to regional ó1 (N23°E) during 1981-1986 and 2004-2008, bimodal orientations (~N-S and ~E-W) during 1987-2004, and bimodal orientations at ~N-E and ~S-W from 2008-2011. These orientations are believed to be due to pressurization accompanying the shallow intrusion and subsequent eruption of magma as domes during 1981-1986 and 2004-2008, and the buildup of pore pressure beneath a shallow seismogenic volume during 1987-2004 and 2008-2011.
Chapter 4 presents a study using receiver functions, which show the relative response of the Earth beneath a seismometer. Receiver functions are produced by deconvolving the vertical component of a seismogram from the horizontal components. The structure of the ground beneath the seismometer can then be inferred from the arrivals of P-to-S converted phases. Receiver functions were computed for the Katmai Volcanic Group, Alaska, at two seismic stations (KABU and KAKN) between January 2005 and July 2011. Receiver functions from station KABU clearly showed the arrival of the direct P-wave and the arrival from the Moho; however, receiver functions from station KAKN did not show the arrival from the Moho. In addition, changes in the amplitude and polarity of arrivals on receiver functions suggested that the structure beneath both KABU and KAKN was complex. Station KABU is likely underlain by dipping layers and/or anisotropy, while station KAKN may lie over a basin structure, an attenuating body, or some other highly complex structure. However, it is impossible to say for certain what the structure is under either station as the azimuthal coverage is poor and thus the structure is unable to be modeled.
This dissertation also includes a section (Chapter 6) on the assessment of spreadsheet-based modules used in two Introductory Physical Geology courses at the University of South Florida (USF). When faculty at USF began using spreadsheet-based modules to help teach students math and geology concepts the students complained that they spent more time learning how to use Excel than they did learning the concepts presented in the modules. To determine whether the sharp learning curve for Excel was hindering learning we divided the students in two Introductory Physical Geology courses into two groups: one group was given a set of modules which instructed them to use Excel for all calculations; the other group was simply told to complete the calculations but was not instructed what method to use. The results of the study show that whether or not the students used Excel had very little to do with the level of learning they achieved. Despite complaints that Excel was hindering their learning, students in the study attained high gains for both the math and geology concepts presented in the modules whether they used Excel or not.

Texto completoResumen
Musculoskeletal disorders continue to be a leading source of lost workdays across all industries. Common ergonomics assessment tools may include criteria extraneous to the stresses at specific companies or industries. Therefore, the creation of assessment tools, based on scientifically validated methods, with industry- or company-specific stresses may be of benefit. The BMW Group has developed the Safety and Ergonomics Risk Assessment (SERA) tool. This ergonomics assessment method incorporates the most up-to-date scientific methods and international standards, and is used worldwide in all production facilities of the BMW Group. As noted above, a major advantage of SERA over conventional ergonomics tools is the focus on ergonomics stresses common to automobile manufacturing and the consequent exclusion of irrelevant parameters, thereby reducing the time, effort, and training required for workplace assessments. Other advantages include the international uniformity of assessments and a web- and database-implementation allowing for easily comparable international reporting. The implementation of this method at the BMW Group has enabled a greater transparency for ergonomics across all international plants, and more effective and targeted ergonomics interventions. This publication will outline the basic motivation for SERA, highlight the relevant scientific sources and international standards, and general steps of an evaluation.

This study analyzes the determinants of success of a group of public schools that served students of low socioeconomic status (Excellence with Equity study). Based on Prova Brazil data, we test whether there is a difference between the prevalence of school factors in the 215 schools identified by the Excellence with Equity study compared to schools with similar characteristics in 2007 but which did not show the same performance regarding the learning of their students thereafter. Taking into account statistical significance, results show that the treatment schools have principals who have been more highly rated by teachers for their leadership attributes; better facilities and operating conditions; more cohesive management and teaching teams; better working conditions for teachers; more learning opportunities; and less school violence. It is also possible to infer that the presence of better educational and infrastructure-related conditions in treatment schools may be a result of the effective management of resource.

Texto completoResumen
A significant amount of effort has been expended in the area of advancing pipeline dent remaining life assessment methods beginning in the late 1980s and extending to the current day. Initial research efforts were primarily empirical in nature while more recent research efforts have incorporated finite element modelling. Coupled with advancements in assessment techniques, the capabilities of advanced in-line inspection (ILI) tools have increased to a point where they can provide consistent, reliable information that is suitable for dent assessments. As a result of these advancements in assessment models and ILI tools, operators can now perform remaining life assessments using ILI data, and a multitude of remaining life assessment models are available, including solutions from the European Pipeline Research Group (EPRG), Pipeline Research Council International (PRCI), American Petroleum Institute (API), and finite-element based approaches. In addition to these remaining life assessments, many operators routinely perform strain-based assessments based on guidance from ASME B31.8. To date, there have been few studies comparing the various assessment methods on large numbers of dents, and as a result, significant questions persist as to the conservatism inherent in each method. In addition, the EPRG and PRCI methods are largely based on full-scale testing and finite-element models performed with idealized indenter shapes while actual pipeline dents typically exhibit complex shapes and interactions between multiple dents. Each model also has limitations and advantages that are discussed in this paper, such as ease of use and how pipeline geometry and weld association are considered. This paper provides a robust comparison of selected dent assessment methodologies on 220 actual dents from a 24-inch pipeline with depths ranging from 0.6–4.5% OD, and 32 dents from a 30-inch line with depths ranging from 1–2.5% OD. The assessment includes both top and bottom of line dents and investigates the influence of restraint on remaining life. The results presented in the paper are based on high-resolution ILI caliper data collected during two in-line inspections. Furthermore, the paper provides statistical comparisons between strain and remaining life methodologies and also between the various remaining life assessments. The paper also provides a comparison of the restraint parameter from the PRCI model with calculated stress concentration factors from finite-element models. The paper provides a first of its kind comparison of the various methods and discusses how the work may be extended to other pipe diameters and wall thicknesses.

Background. In the practice of clinical research, it is traditionally accepted to evaluate parameters that characterize the degree of impairment or loss of the function of an organ or system, and not their preservation. A fundamental change in the approach distinguishes a new trend in modern medicine, which makes it possible to assess the degree of preservation of functional resources, which was the basis of this study.Study purpose: To develop a method for dynamic quantitative assessment of the severity of arterial hypertension and evaluate the relationship between a qualitative indicator of arterial hypertension and a quantitative indicator.Instruments and Data Collection Procedure. Index of adaptive aptitude (IAA) (patent for invention No. 2342900 "Method for eavaluation of the functional reserves of the body", author - Kurnikova I. A.). using automated assessment (certificates of official registration No. 2007614560 and No. 2007613898).IAA=0.011(P-P*)+0.014(S-S*)+0.008(D-D*)+0.009(W-W*),Where: P - actual heart rate (b/min.); P* - ideal pulse rate (beats/ min.); S - systolic blood pressure, actual average per day (mm Hg); S* – ideal systolic blood pressure (mm Hg); D - diastolic blood pressure, actual average per day (mm Hg); D* - ideal diastolic blood pressure (mm/Hg); W - body weight at the time of examination (kg); W* - ideal body weight (kg); H - patient's height at the time of examination (cm).Assessment of daily heart rate variability on the Valenta system, equipped with a program for computer processing of spectral analysis indicators.Results:- 143 patients with arterial hypertension (AH) were examined. The relationship between a qualitative indicator - the severity of AH and quantitative indicators - rehabilitation potential, the numerical value of which is PAS, the circadian index (CI) as an indicator of increased sensitivity of the heart rate to sympathetic stimulation, and the LF/HF vago sympathetic balance coefficient, which increases with hypersympathatic tone, was considered. Statistical analysis of the surface plot using the weighted least squares distance allowed this relationship to be clearly demonstrated. Quantitative analogue of the Framingham arterial hypertension severity scale (AHSS) in a specific patient (certificate for invention №. 201152181)AHSS = 119,31 + 2,22× (CI) - 2,03× (IAA) - 1,33×(2×(CI)) + 2,72×(CI)× (IAA) + 7,06×(IAA)where: AHSS less than 120 - normal. Mild AHSS = 121 – 130 points; average severity of AHSS = 131 – 140 points; severe AHSS - 141 points or more. The effectiveness of rehabilitation is good with AHSS less than 120, satisfactory - with 121 - 130; unsatisfactory - more than 131.For illustration, the data of 54 patients are presented. Observation group "1" - patients with AH (BMI<25), mean age - 49±1.9 years (19 people). Observation group "2" - patients with metabolic syndrome (BMI>25; HOMA index> 2.5), mean age - 50±1.7 (35 people). All patients were assessed for the severity of hypertension according to the WHO criteria and the AHSS index at the beginning of the study. Normal value was achieved in 41.8% in 1st group during treatment, in 47.1% there was a decrease in the severity of AH according to AHSS. In group 2, in patients with metabolic syndrome during treatment, it was possible to normalize blood pressure in 55.8%, and to obtain satisfactory results in 35.9%.Conclusion. Developed mathematical modeling methods, a quantitative analogue indicator of the severity of arterial hypertension - AHSS allows you to dynamically monitor the effectiveness of treatment and evaluate the achieved result based on a quantitative assessment within the severity indicated by the classification. The effectiveness of the rehabilitation of patients with hypertension is considered sufficient if the AHSS decreases below the value of 120 units or one level from the baseline

Engineering design is typically a team effort. Design teams frequently need to push technical boundaries to solve the most relevant challenges faced by our society. A significant area of research across multiple fields of investigation, including engineering, is the understanding and use of an individual’s cognitive attributes in the process of assembling productive teams. This research proposes an approach to assembling an engineering design team by first defining the desirable cognitive attributes in the team members. Subsequently, based on individual cognitive profile assessments along these attributes, an exhaustive list of possible design teams is investigated based on their cumulative attribute level. We compare the performance of two teams predicted to perform at different levels, and our results verify the differences between the observations of team interactions and the quality of designs produced. In addition to self-assessments, we also investigate the brain activity of the respondents using electroencephalography (EEG) to evaluate performance in an individual and a team setting. This analysis intends to highlight the characteristics of an individuals’ brain activity under different circumstances to reveal if these characteristics contribute to the success of a design team. EEG data revealed observations such as correlation between raw amplitude and level of team contribution, a higher variation in the channel power spectral density during individual versus team tasks, and a degradation of alpha activity moving from individual to group work. The results of this research can guide organizations to form teams with the necessary cognitive attributes to achieve the optimum design solution.

Engineering students are often faced with many assessment points during a semester. One of the more common assessments in an engineering programme are group-based, design and build projects. These projects often require a disproportionate amount of time due to coordination between members and resources for acquiring materials. This study relates an attempt to reduce this burden by utilising a common project as an assessment point for two separate courses: Practical Prototyping Skills and Introduction to Energy Engineering. The challenges faced by instructors in creating a project that would adequately address their individual learning outcomes are presented, along with the students’ perspective on this approach. Student surveys indicated that there was a clear understanding of how the project related to both courses and that they had sufficient support for the project, while lecturers highlighted several positive outcomes such as more student emphasis on the project, a higher standard of project and collegial support in the design and administration of the project.

Texto completoResumen
The potential for wave energy extraction can be obtained from the analysis of the wave climate which can be determined with numerical models. The wave energy devices can be deployed in offshore, nearshore and shoreline. From this reason, it is important to be able to assess properly the spatial distribution of the wave energy in various locations from the offshore to the coastline in a specific area. The methodology proposed here considers a SWAN based wave model system focusing in the Portuguese continental coastal environment from deep water towards the nearshore. An analysis of the average and high energetic conditions was first performed for a ten-year period, between 1994 and 2003, considering the most relevant in situ measurements available in the Portuguese nearshore. In this way both the average and high energetic conditions corresponding to the Portuguese continental costal environment have been properly defined. For the most relevant average wave conditions, SWAN simulations were performed in some medium resolution areas covering the northern and central parts of Portugal continental, which are traditionally considered richer in wave power resources. The present work allows the identification of some locations in the continental coastal environment of Portugal with greater potential from the point of view of wave power resources. An important observation is related to the fact that the wave power depends on the product between the energy density spectrum and the group velocity of waves. This means that, although the significant wave height is a relevant parameter when assessing the wave power in a specific site, a location having in general higher wave heights is not necessarily also the richest in wave power.

Finite element weld residual stress modelling procedures involve complex non-linear analyses where many assumptions and approximations have to be made by the analyst. Weld modelling guidelines for inclusion in the R6 defect assessment procedure are in preparation and will be accompanied by a series of validation benchmarks that can be used to evaluate the accuracy of weld modelling procedures and assess their suitability for use in fracture assessments. It is intended to base one of the benchmarks on a stainless steel bead-on-plate weldment that has been extensively studied by members of Task Group 1 of the NeT European Network project. This paper uses round robin residual stress measurements from the NeT project to derive a statistically based ‘best estimate’ distribution of transverse stress passing through the wall-section at mid-length of the bead-on-plate weldment. The accuracy of a state-of-the-art residual stress prediction is benchmarked against the best estimate measurements using a root mean square error analysis and comparisons of decomposed components of stress. The appropriateness of using the predicted residual stresses in fracture assessments is assessed by comparing stress intensity factors based on the measured and predicted distributions of stress. The results from these studies will be used to help establish accuracy targets and acceptance criteria for the welding benchmark.

Texto completoResumen
The aero-engine design process is highly iterative, multidisciplinary in nature and complex. The success of any engine design depends on best exploiting and considering the interactions among the numerous traditional engineering disciplines such as aerodynamics and structures. More emphasis has been placed lately on system integration, cross disciplines leveraging of tools and multi-disciplinary-optimization at the preliminary design phase. This paper investigates the automation of the airfoil generation process, referred to as Rapid Airfoil 3D (RAF 3D), for uncooled high pressure turbine blades at the preliminary design phase. This Matlab based program, uses the turbine aero meanline (TAML) in parallel with a database of previously designed P&WC airfoils, in-house design rules and best practices to define a pre-detailed airfoil shape which can be fed back to other analytical groups for pre-detail analyses, such as for structures and vibrations. Resulting airfoil shapes have been aerodynamically validated using an in-house 3D RANS code. RAF 3D will shorten the turnaround time for P&WC’s turbine aerodynamics group to provide a preliminary 3D airfoil shape to turbine structures group by up to a factor of ten. Additionally, the preliminary assessments of stress and vibration specialists will be more accurate as their assessments will be based on an airfoil that has had inputs from all functional groups even though it is “first pass” design.

Texto completoResumen
One of the most debated parts of the IDB-9 Agreement was the requirement that the Inter-American Development Bank (IDB or Bank) enhance its macroeconomic analysis and link it to its country programming to avoid lending in unsustainable macroeconomic situations. The IDB-9 Agreement mandated that the Chief Economist prepare annual Macroeconomic Sustainability Assessments for each borrowing country and that a positive judgment on sustainability is one of the prerequisites, among others, for maintaining the Bank's aggregate exposure with the country including both sovereign and non-sovereign operations. OVE finds that the MSA requirement has been substantially implemented but faces many difficulties that seriously impede its likely effectiveness. The quality of the MSAs, though reasonable given the resources allocated, lacks depth in many areas, particularly financial sustainability and inflation. More generally, there is no methodology that could reliably do what is expected: predict macroeconomic crises in the near term. There are few checks and balances in the system, and none relating to the Chief Economist's conclusion and determination of sustainability. The MSA process entails significant costs for the Bank, including in country relations and IDB Board cohesion and collaboration. Though the MSA process has the potential to further the underlying IDB-9 goal of preventing lending in unsustainable macroeconomic situations, the process will not achieve the broader objective of stopping increases in Bank exposure for the foreseeable future: existing IDB disbursement and repayment schedules will lead to increasing exposure in almost all borrowing countries in the coming 5-10 years. OVE suggests that the Governors, the Board, and Management reconsider the design of the MSA process to align benefits and costs more closely. A useful way to think about changes is to "unbundle" the two rationales for MSAs -limiting IDB's credit risk and promoting development effectiveness. The credit risk rationale argues for the type of short-term focus and yes-no decision-making used in the MSAs, and Management may wish to strengthen the ability of its risk management group to perform independent credit risk assessment of the sovereign portfolio. The development rationale argues for a more medium-term instrument with a broader focus, as macroeconomic policies are not the only ones that matter for development. One option would be to strengthen the Bank's Independent Macroeconomic Assessments for policy-based lending, with clear guidelines to ensure their effective coverage and implementation. IDB could also strengthen its macroeconomic and policy analysis through its regular program of economic and sector work. It is clearly feasible for the IDB to have a stronger role than it now has in policy analysis and advice to its borrowing countries.

Calijuri, Mónica y Phelippe Toledo Pires de Oliveira. Cooperative Compliance in Brazil: What Does the Future Hold? Inter-American Development Bank, octubre de 2023. http://dx.doi.org/10.18235/0005204.
Texto completoResumen
The concept of cooperative compliance has gained momentum in recent years as tax authorities seek to establish more collaborative relationships with taxpayers, especially in member countries of the Organisation for Economic Co-operation and Development (OECD). The subject had not arisen with the same interest in Latin America and the Caribbean. Brazil, in particular, has been cautious in its approach to cooperative compliance after a timid attempt some years ago. However, this has been changing since the launch of the Confia pilot program in 2021, where the Brazilian Federal Revenue (RFB) is collaborating with a group of large taxpayers participating in the pilot. Confia's main objective is to develop a relationship of trust between tax authorities and taxpayers by promoting a culture of compliance based on cooperation and transparency. This paper highlights the benefits of cooperative compliance including improved relationships between tax authorities and taxpayers, greater tax certainty, and reduced compliance and litigation costs. These benefits can help make Brazilian companies more competitive globally and improve risk assessments for tax administrations. Some initiatives taken by Brazilian tax authorities to enhance their relationship with taxpayers, including the experience of the RFB with Confia, could provide valuable lessons for other Latin American and Caribbean countries.

Texto completoResumen
A risk assessment methodology was developed for atmospheric, accidental natural gas and highly volatile liquid releases from near-well equipment, for underground storage in caverns and formations (gas only). The assessment was based on certain standard configurations defined by an Industry Project Group associated with this study. Fault trees we developed for storage well components associated with the following equipment modules: the meter run, wellhead, downhole, emergency shutdown, and displacement brine (HVL storage only) subsystems. Risk was assessed as the probability of a significant hydrocarbon release. Data for populating the fault tree examples were taken from open literature sources of generic data; based on operator experience; and based on engineering judgment. Opportunities for further development and enhancement of the current methodology and results are discussed.

Texto completoResumen
This assessment synthesizes information about current and projected climate and related impacts at Martin Van Buren National Historic Park (MAVA) in order to help park stewards understand, plan, and manage for climate change. Working with a group of park managers, scientists, and local stake-holders, six key park resources were identified for assessment herein: Climate, Water quantity, Phenology, Agriculture, Trees, and Cultural resources. Where data was available, this analysis assessed current condition and considered mid-century (2030–2060) and end-of-century (2100) impacts based on a range of projected future climate conditions, including reduced, low, high and highest emission pathways. Climate change stressors identified for MAVA include: Increased temperature, increased hot days, increased precipitation, increased extreme precipitation events, increased flooding and erosion, shifting ranges of both native species and pest, pathogen and weed species, and phenological shifts and mismatches.

Texto completoResumen
This paper discusses the main issues concerning sovereign fiscal and financial risks from public–private partnerships (PPPs) with a focus on contingent liabilities (CLs). It is based on the presentations and discussions that took place during the XI Annual Meeting of the Group of Latin American and the Caribbean Debt Management Specialists (LAC Debt Group), held in Barbados in August 2015. The main issues discussed include PPP risks assessment, institutional framework for PPP risk management, and accounting and reporting of CLs generated by PPPs. Six country cases (Chile, Colombia, Costa Rica, Honduras, Suriname, and Turkey) are presented to illustrate experiences with different degrees of development regarding the management of risks and CLs related to PPPs. The document concludes that PPP risk management should encompass the whole lifecycle of a PPP project, risks need to be identified and CLs must be estimated and monitored, and the institutional capacity of governments to evaluate and manage PPP risks plays a central role in the successful development of PPP contracts. Although institutional capacities in this regard have improved in recent years, estimations of CLs involved in PPPs are not regularly performed, and there is still room for improvement on the assessment, measurement, registration, budgeting, and reporting of risks and CLs related to PPPs.

Texto completoResumen
Tap and Reposition Youth (TRY) was a four-year initiative undertaken by the Population Council and K-Rep Development Agency to reduce adolescents’ vulnerabilities to adverse social and reproductive health outcomes by improving livelihoods options. The project targeted out-of-school adolescent girls and young women aged 16–22 residing in low-income and slum areas of Nairobi. TRY used a modified group-based micro-finance model to extend integrated savings, credit, business support, and mentoring to out-of-school adolescents and young women. A longitudinal study of participants was conducted with a matched comparison group identified through cross-sectional community-based studies, undertaken at baseline and endline to enable an assessment of changes associated with the project. This report states that 326 participants and their controls were interviewed at baseline and 222 pairs were interviewed at endline. The results suggest that rigorous micro-finance models may be appropriate for a subset of girls, especially those who are older and less vulnerable. The impact on noneconomic indicators is less clear. Additional experimentation and adaptation is required to develop livelihoods models that acknowledge and respond to the particular situation of adolescent girls.

Review question / Objective: P:Adult patients (age ≥ 18 years) diagnosed with stroke based on relevant clinical examination; I:Intervention group with rTMS alone or in combination with other treatments with rTMS; C:Control group received sham treatment or no rTMS; O: Upper extremity function:the Fugl-Meyer Assessment Upper Extremity (FMA-UE); Hand function:box and block test(BBT), nine-hole peg test(NHPT), and Purdue pegboard test(PPT); S:Randomized controlled trials (rather than crossover designs). Condition being studied: In Europe, more than 1 million new cases of stroke are reported each year. The absolute number of stroke patients is expected to increase in the near future due to the progressive aging of the population. Approximately 50-80% of stroke survivors present with upper extremity dysfunction. Recovery of upper extremity function is associated with improvements in activities of daily living and mental health. However, few stroke survivors show full recovery of upper extremity function 6 months after stroke. In addition, rehabilitation has a limited impact on the recovery of hand motor function.
