Towards Designing a Performance Measurement System for the CGIAR : Draft Report

The System Office established the Working Group on Performance Measurement in May 2003, under the Co-Chairmanship of two ExCo members: Kevin Cleaver (ExCo/FC Chair) and Luis Arango (ExCo/PC member). Three sets of activities were carried out in preparation for the first meeting of the WG on September 5, 2003:(1) The CGIAR Secretariat prepared a Sourcebook on Performance Measurement in Research Institutions and Programs as background on approaches and methods of performance measurement being used in similar organizations globally.(2) Members of the WG shared additional information relevant to the objectives of the exercise (e.g., papers, articles);(3) A sub-group of the WG (made up of technical experts and resource persons1) met for a two day workshop on August 11-12, 2003 to discuss and outline performance measurement options that could be considered by the WG at its September 5 meeting, as a means of facilitating the task of the WG. This paper reflects the outcome of this preparatory workshop.The paper is organized as follows: the remainder of this chapter discusses the rationalebehind the worldwide trends towards Performance Measurement and offers definitions ofsome key terms. Chapter 2 focuses on the CGIAR, describing potential purposes and usesof performance measurement, identifying possible key elements of a performance measurement system, and outlining how such a system could fit into the planning and evaluation processes of the CGIAR. The final chapter summarizes the main conclusions and recommendations. This report was discussed during the Business Meeting at AGM 2003

Performance pay, group selection and group performance

Within a laboratory experiment we investigate a principal-agent game in which agents may, first, self-select into a group task (GT) or an individual task (IT) and, second, choose work effort. In their choices of task and effort the agents have to consider pay contracts for both tasks as offered by the principal. The rational solution of the game implies that contract design may not induce agents to select GT and provide positive effort in GT. Furthermore it predicts equal behavior of agents with different productivities. In contrast, considerations of trust, reciprocity and cooperation – the social-emotional model of behavior – suggest that contract design can influence the agents’ willingness to join groups and provide effort. We analyze the data by applying a two-step regression model (multinomial logit and tobit) and find that counter to the rational solution, contract design does influence both, task selection and effort choice. The principal can increase participation in work groups and can positively influence group performance. Larger payment increases the share of socially motivated agents in work groups. The selection effect is larger than the motivation effect

The depression report: a new deal for depression and anxiety disorders.

Crippling depression and chronic anxiety are the biggest causes of misery in Britain today. They are the great submerged problem, which shame keeps out of sight. But if you mention them, you soon discover how many families are affected. According to the respected Psychiatric Morbidity Survey, one in six of us would be diagnosed as having depression or chronic anxiety disorder, which means that one family in three is affected. That is the bad news. The good news is that we now have evidence-based psychological therapies that can lift at least a half of those affected out of their depression or their chronic fear. These new therapies are not endless nor backwardlooking treatments. They are short, forward-looking treatments that enable people to challenge their negative thinking and build on the positive side of their personalities and situations. The most developed of these therapies is cognitive behaviour therapy (CBT). The official guidelines from the National Institute for Clinical Excellence (NICE) say these treatments should be available to all people with depression or anxiety disorders or schizophrenia, unless the problem is very mild or recent. But the NICE guidelines cannot be implemented because we do not have enough therapists. In most areas waiting lists for therapy are over nine months, or there is no waiting list at all because there are no therapists. So, if you go to the GP, all that can be provided is medication (plus at some surgeries a little counselling). But many people will not take medication, either because they dislike the side effects or because they want to control their own mood. The result is tragic. Only one in four of those who suffer from depression or chronic anxiety is receiving any kind of treatment. The rest continue to suffer, even though at least half of them could be cured at a cost of no more than £750. This is a waste of people’s lives. It is also costing a lot of money. For depression and anxiety make it difficult or impossible to work, and drive people onto Incapacity Benefits. We now have a million people on Incapacity Benefits because of mental illness – more than the total number of unemployed people receiving unemployment benefits. At one time unemployment was our biggest social problem, but we have done a lot to reduce it. So mental illness is now the biggest problem, and we know what to do about it. It is time to use that knowledge. 2 But can we afford the £750 it costs to treat someone? The money which the government spends will pay for itself. For someone on Incapacity Benefit costs us £750 a month in extra benefits and lost taxes. If the person works just a month more as a result of the treatment, the treatment pays for itself. So we have a massive problem – the biggest problem they have for one in three of our families. But we also have a solution that can improve the lives of millions of families, and cost the taxpayer nothing. We should implement the NICE guidelines; and most people with mental illness should be offered the choice of psychological therapy. Everyone who wants something done should write to their MP calling for action.

Physics and Performance Evaluation Group

We summarize the objectives and results of the ``international scoping study of a future neutrino factory and superbeam facility'' (ISS) physics working group. Furthermore, we discuss how the ISS study should develop into a neutrino factory design study (IDS-NF) from the point of view of physics and performance evaluation.Comment: 3 pages, 1 figure.

The Effects of Coworker Relationships, Involvement, and Supportiveness on Job Satisfaction and Performance

Past research has indicated that relationships, involvement, and supportiveness have an effect on job satisfaction and performance. A study was done on Gettysburg College students who have had experience with group work. Sixty-four (29 males, 35 females) Gettysburg College students were used as participants in the study. The study was split fairly evenly between sophomores, juniors, and seniors. To start, the survey included two demographic questions: gender and class year. Participants completed an online survey about the relationships among group mates, group involvement, and group support experience. Questions about the overall satisfaction and performance were also included. A correlational design was used to analyze the data. The results of this study concluded that there was significant association between positive relationships and involvement and job satisfaction and group performance in a group scenario. There was a significant association between group support and job satisfaction, but not performance

Effectiveness of group interaction on conceptual standardized test performance

We analyze the effectiveness of working in pairs on the Conceptual Survey of Electricity and Magnetism test in a calculus-based introductory physics course. The group performance shows large normalized gain and evidence for co-construction. We discuss the effect of pairing students with different individual achievements.Comment: 4 pages, submitted to proceedings of PER conference, 2002, Bois

High-performance functional renormalization group calculations for interacting fermions

We derive a novel computational scheme for functional Renormalization Group (fRG) calculations for interacting fermions on 2D lattices. The scheme is based on the exchange parametrization fRG for the two-fermion interaction, with additional insertions of truncated partitions of unity. These insertions decouple the fermionic propagators from the exchange propagators and lead to a separation of the underlying equations. We demonstrate that this separation is numerically advantageous and may pave the way for refined, large-scale computational investigations even in the case of complex multiband systems. Furthermore, on the basis of speedup data gained from our implementation, it is shown that this new variant facilitates efficient calculations on a large number of multi-core CPUs. We apply the scheme to the $t$,$t'$ Hubbard model on a square lattice to analyze the convergence of the results with the bond length of the truncation of the partition of unity. In most parameter areas, a fast convergence can be observed. Finally, we compare to previous results in order to relate our approach to other fRG studies.Comment: 26 pages, 9 figure

Group Communication Patterns for High Performance Computing in Scala

We developed a Functional object-oriented Parallel framework (FooPar) for high-level high-performance computing in Scala. Central to this framework are Distributed Memory Parallel Data structures (DPDs), i.e., collections of data distributed in a shared nothing system together with parallel operations on these data. In this paper, we first present FooPar's architecture and the idea of DPDs and group communications. Then, we show how DPDs can be implemented elegantly and efficiently in Scala based on the Traversable/Builder pattern, unifying Functional and Object-Oriented Programming. We prove the correctness and safety of one communication algorithm and show how specification testing (via ScalaCheck) can be used to bridge the gap between proof and implementation. Furthermore, we show that the group communication operations of FooPar outperform those of the MPJ Express open source MPI-bindings for Java, both asymptotically and empirically. FooPar has already been shown to be capable of achieving close-to-optimal performance for dense matrix-matrix multiplication via JNI. In this article, we present results on a parallel implementation of the Floyd-Warshall algorithm in FooPar, achieving more than 94 % efficiency compared to the serial version on a cluster using 100 cores for matrices of dimension 38000 x 38000

Does the group leader matter? The impact of monitoring activities and social ties of group leaders on the repayment performance of groupbased lending Eritrea

This paper analyzes whether the effects of monitoring and social ties of the group leader and other group members on repayment performance of groups differ, using data from an extensive questionnaire held in Eritrea among participants of 102 groups. We hypothesize that the monitoring activities and social ties of the group leader have a stronger positive impact on the repayment performance of groups. The results show that social ties of the group leader do have a positive effect on repayment performance of groups, whereas this is not true for social ties of other group members. We do not find evidence for the hypothesis that monitoring activities of the group leader have a stronger positive impact on group repayment performance. All variables measuring monitoring activities, either of the group leader or the other group members, are found to be statistically insignificant.
