    __Abstract__ Het idee dat evaluatie kan bijdragen aan het verbeteren van beleid is niets nieuws onder de zon. Al in de jaren ’80 van de vorige eeuw bloeide evaluatie op met de bedoeling beleidsformulering en beleidsuitvoering te informeren, en in het hedendaagse ‘evidence-based’ tijdperk is evaluatie meer dan ooit een bloeiende praktijk. 1 Nederland volgde historisch weliswaar een ander en sneller traject dan Belgie¹, waar evaluatie slechts na de millenniumwisseling algemeen ingang vond.2 De potentie van evaluatie is tegenwoordig niettemin grotendeels (h)erkend en wordt gevat in adagia als ‘leren van evalueren’. Er worden met regelmaat evaluatiestudies uitgevoerd, maar opvallend is dat deze in toenemende mate ook het gebruik van evaluatieonderzoek zelf betreffen

    An evaluation can be conducted in-house or can be outsourcedto an external party. Yet organizations do not always have fulldiscretion to decide on the locus for evaluation implementation.Certain attributes often push the organization in one directionor another. Via a systematic pairwise comparison of attributes of18 organizations in the Flemish (Belgian) public sector, we wereable to indicate the conditions that matter most in determiningthe locus of policy evaluation implementation. Our findings canthus enrich existing guidelines on the advantages and disadvantagesof internal and external evaluations.The politics and administration of institutional chang

    A capacity assessment framework for the fit-for-purpose land administration systems: the use of unmanned aerial vehicle (UAV) in Rwanda and Kenya

    This article presents a novel capacity assessment framework, coined as Fit-For-Purpose capacity assessment framework (FCAF), to measure the capacity of the land administration system compliant with the Fit-For-Purpose approach. The framework incorporates legal, political, operational, social, technical, and technological capacity conditions and provides a holistic view of the capacity development pathways. The FCAF is designed by merging six capacity dimensions, namely regulations, political system, operational unit, social norms, land recording techniques, and software. FCAF systematically identifies context-specific, enabling and impeding capacity components and thus provides a basis to develop the necessary capacity development strategies and interventions. Specifically, FCAF can serve as a useful heuristic for the development of the capacity development strategies for the adaptation and sustainability of the geospatial technologies in land administration systems. In the article, by assessing the capacity needs for the adaptation of unmanned aerial vehicle (UAV) technology in Rwandese and Kenyan land administration systems, the efficacy of the FCAF is tested. The findings suggest that in Rwanda, capacity conditions are more supportive of an easier uptake of UAV. Nonetheless, weak market conditions and strict regulations concerning UAV call for attention. In Kenya, existing institutional and political challenges in the land administration system raise concerns about the reliability and attainability of UAV under the current framework conditions. Despite that, there are more supportive market conditions in Kenya in comparison to Rwanda and multiple non-governmental and private actors that can bolster the adaptation process into a more sustainable and scalable land administration system.

    Impact of performance audit on the Administration: A Belgian study (2005-2010)

    Get PDF
    Purpose This study of the impact of Belgian Court of Audit on the federal Administration for the 2005 to 2010 period aims to highlight the auditors’ influence on the management of governmental organizations through the performance audits they have been conducting since 1998. A set of ten variables allows us to measure the three types of uses of performance auditors’ work by auditees: instrumental, conceptual and strategic uses. Design/methodology/approach A survey was sent out to a total of 148 respondents identified by the authorities of the targeted organizations. 47 usable questionnaires were completed (32% response rate). Findings The Court of Audit’s impact on the audited entities did not provoke radical changes in the auditees’ organizational life but the intervention of the auditors was nevertheless noticeable. The nature of the impact was rather conceptual than strategic or instrumental. And the negative consequences on auditees anticipated in the literature were not observed. Research limitations/implications Given the five-year period covered by the study which was made in 2014 (four years after 2010), it had to deal with the mortality of respondents and the loss of organizational memory. Practical implications The study gives more accurate insights about the influence that Supreme Audit Institutions actually exert on audited Administrations through their performance audits. Originality/value Since Supreme Audit Institutions have been mandated to evaluate government’s economy, efficiency and effectiveness for almost 40 years in the western democracies, it is mandatory that their actual ability to influence Administrations be documented more abundantly and independently by academic researchers.  The politics and administration of institutional chang

    Conservative solutions for progress: on solution types when combining QCA with in-depth Process-Tracing

    Get PDF
    What is the most appropriate QCA solution type when engaging in a multimethod design that includes QCA and in-depth process-tracing (PT)? While either the intermediate or the parsimonious solution are generally favored in QCA-only studies, we identify important challenges that can emerge when selecting those solutions in a QCA-PT multimethod study. We particularly highlight the risk of mechanistic heterogeneity, omitted conditions, and draw the attention on the issue of generalization. We discuss each of these intertwined challenges in depth, and explain why the conservative solution is useful to consider in addressing them. We substantiate our arguments by drawing on a recently completed evaluation study that was commissioned by the Flemish ESF Agency in Belgium. In the study, we combined QCA and theory-guided in-depth process-tracing to uncover under what combinations of conditions (QCA) a training programme would lead to successful training transfer and how (PT) this happened in the successful cases. The article highlights the need to carefully consider the selection of solution types in any multimethod design comprising QCA.The politics and administration of institutional chang

    Disentangling the drivers of future Antarctic ice loss with a historically calibrated ice-sheet model

    Get PDF
    We use an observationally calibrated ice-sheet model to investigate the future trajectory of the Antarctic ice sheet related to uncertainties in the future balance between sub-shelf melting and ice discharge, on the one hand, and the surface mass balance, on the other. Our ensemble of simulations, forced by a panel of climate models from the sixth phase of the Coupled Model Intercomparison Project (CMIP6), suggests that the ocean will be the primary driver of short-term Antarctic mass loss, initiating ice loss in West Antarctica already during this century. The atmosphere initially plays a mitigating role through increased snowfall, leading to an Antarctic contribution to global mean sea-level rise by 2100 of 6 (−8 to 15) cm under a low-emission scenario and 5.5 (−10 to 16) cm under a very high-emission scenario. However, under the very high-emission pathway, the influence of the atmosphere shifts beyond the end of the century, becoming an amplifying driver of mass loss as the ice sheet's surface mass balance decreases. We show that this transition occurs when Antarctic near-surface warming exceeds a critical threshold of +7.5 ∘C, at which the increase in surface runoff outweighs the increase in snow accumulation, a signal that is amplified by the melt–elevation feedback. Therefore, under the very high-emission scenario, oceanic and atmospheric drivers are projected to result in a complete collapse of the West Antarctic ice sheet along with significant grounding-line retreat in the marine basins of the East Antarctic ice sheet, leading to a median global mean sea-level rise of 2.75 (6.95) m by 2300 (3000). Under a more sustainable socio-economic pathway, we find that the Antarctic ice sheet may still contribute to a median global mean sea-level rise of 0.62 (1.85) m by 2300 (3000). However, the rate of sea-level rise is significantly reduced as mass loss is likely to remain confined to the Amundsen Sea Embayment, where present-day climate conditions seem sufficient to commit to a continuous retreat of Thwaites Glacier.</p

    Glaciological characteristics in the Dome Fuji region and new assessment for 1.5 Ma old ice

    The retrieval of a continuous Antarctic ice-core record dating back 1.5 Ma is a key objective in palaeo-climatologyin order to understand why the frequency of ice ages changed from 40 ka to 100 ka approximately 1 Ma ago. Here,we investigate the probability that the Dome Fuji region in East Antarctica contains ice more than 1.5 Ma old.We use a new radar dataset acquired in the Antarctic seasons 2014/15 and 2016/17 to improve the ice thickness map. Compared to previous maps of the region, the new dataset shows a more complex landscape with networks of valleys and mountain plateaus. We use the new dataset as input in a thermokinematic model that incorporates uncertainties in geothermal heat flux values in order to improve the predictions of potential ice-core sites. Our results indicate several areas of interest, especially the region immediately south of Dome Fuji station appears to be a good candidate site. An initial assessment of basal conditions revealed the existence of several wet-based areas and further radar data analysis shows overall high continuity of layer stratigraphy in the region. Thus, if a new drill operation were to take place in this area, extending the age-depth information from the Dome Fuji ice core to a new ice-core drill site is a viable option

    CADM1 is a strong neuroblastoma candidate gene that maps within a 3.72 Mb critical region of loss on 11q23

    <p>Abstract</p> <p>Background</p> <p>Recurrent loss of part of the long arm of chromosome 11 is a well established hallmark of a subtype of aggressive neuroblastomas. Despite intensive mapping efforts to localize the culprit 11q tumour suppressor gene, this search has been unsuccessful thus far as no sufficiently small critical region could be delineated for selection of candidate genes.</p> <p>Methods</p> <p>To refine the critical region of 11q loss, the chromosome 11 status of 100 primary neuroblastoma tumours and 29 cell lines was analyzed using a BAC array containing a chromosome 11 tiling path. For the genes mapping within our refined region of loss, meta-analysis on published neuroblastoma mRNA gene expression datasets was performed for candidate gene selection. The DNA methylation status of the resulting candidate gene was determined using re-expression experiments by treatment of neuroblastoma cells with the demethylating agent 5-aza-2'-deoxycytidine and bisulphite sequencing.</p> <p>Results</p> <p>Two small critical regions of loss within 11q23 at chromosomal band 11q23.1-q23.2 (1.79 Mb) and 11q23.2-q23.3 (3.72 Mb) were identified. In a first step towards further selection of candidate neuroblastoma tumour suppressor genes, we performed a meta-analysis on published expression profiles of 692 neuroblastoma tumours. Integration of the resulting candidate gene list with expression data of neuroblastoma progenitor cells pinpointed <it>CADM1 </it>as a compelling candidate gene. Meta-analysis indicated that <it>CADM1 </it>expression has prognostic significance and differential expression for the gene was noted in unfavourable neuroblastoma versus normal neuroblasts. Methylation analysis provided no evidence for a two-hit mechanism in 11q deleted cell lines.</p> <p>Conclusion</p> <p>Our study puts <it>CADM1 </it>forward as a strong candidate neuroblastoma suppressor gene. Further functional studies are warranted to elucidate the role of <it>CADM1 </it>in neuroblastoma development and to investigate the possibility of <it>CADM1 </it>haploinsufficiency in neuroblastoma.</p
