The lack of standardization in the production, organization and dissemination of information in documentation centers and institutions alike, as a result from the digitization of collections and their availability on the internet has called for integration efforts. The sheer availability of multimedia content has fostered the development of many distinct and, most of the time, independent metadata standards for its description. This study aims at presenting and comparing the existing standards of metadata, vocabularies and ontologies for multimedia annotation and also tries to offer a synthetic overview of its main strengths and weaknesses, aiding efforts for semantic integration and enhancing the findability of available multimedia resources on the web. We also aim at unveiling the characteristics that could, should and are perhaps not being highlighted in the characterization of multimedia resources.

OBJECTIVE: To study physician utilization and experience with image-guidance technology for sinus surgery. STUDY DESIGN AND SETTING: Retrospective review of the first 1000 image-guided sinus operations performed by 42 surgeons at an academic medical center. RESULTS: Utilization of image-guidance systems showed a dramatic increase in both number of cases performed and surgeons who used this equipment (70.6% and 92.8%, respectively) during the first 2 years of its availability. Surgical volume subsequently decreased by a mean of 9.3% per year, whereas the number of surgeons using this technology plateaued. The majority of surgeons continued to perform image-guided surgery throughout the study period for selected cases. The knowledge base gained from this experience can best be summarized as a series of lessons learned. CONCLUSION: It is likely that the availability and utilization of image-guidance systems for sinus surgery will continue to increase in the future. Physicians who learn to use this new technology must do so with an appreciation for both its potential benefits and pitfalls.

This study investigates the transformative impact of AI-based Decision Support Systems (DSS) and Big Data Analytics (BDA) on student innovation and employability skills in an era of rapid technological advancement, with a focus on the mediating role of technological acceptance and the moderating role of resource availability. This study, which draws on a wide range of educational contexts and data sources, gives complete knowledge of the complex links between technology adoption, student results, and contextual factors. The results of this study show how AI-based DSS and BDA have a significant impact on musical education. These technological advancements enable tailored instruction and foster students' creative thinking. In order to prepare students for a work market that is rapidly changing, they act as a catalyst for improving employability skills. The study, however, emphasizes the complicated dynamics at work. Technological Acceptance emerges as a major mediating component, underlining the significance of students and instructors freely and effectively accepting technological tools. Furthermore, as a moderating factor, Resource Availability takes center stage, emphasizing the need for equitable access to educational resources to ensure that technology-driven advantages are accessible to all. The results of this study have broad repercussions. The adoption of AI and BDA by educational institutions is encouraged as transformative technologies for enhancing the learning process. Policymakers must create regulations that support equal access to technology and promote an innovative culture in the classroom. This study highlights for students how important it is to adopt new technologies, realizing how important they are in determining both their academic and career paths.

HighlightsThe ARSPivot software seamlessly integrates site-specific irrigation scheduling methods with weather, plant, and soil water sensing systems in the operation of variable-rate irrigation (VRI) center pivot systems.ARSPivot embodies an Irrigation Scheduling Supervisory Control and Data Acquisition (ISSCADA) system that incorporates site-specific irrigation scheduling methods and automates the collection and processing of data obtained from sensing systems supporting them.ARSPivot incorporates a friendly graphical user interface (GUI) that assists in the process of setting up a computerized representation of a coupled ISSCADA VRI center pivot system and simplifies the review of irrigation prescriptions automatically generated based on sensor feedback.ARSPivot’s GUI includes a geographic information system (GIS) that relates sensed data and imported GIS data to specific field control zones.Abstract. The commercial availability of variable-rate irrigation (VRI) systems gives farmers access to unprecedented control of the irrigation water applied to their fields. To take full advantage of these systems, their operations must integrate site-specific irrigation scheduling methods that in turn should be supported by a network of sensing systems. An Irrigation Scheduling Supervisory Control and Data Acquisition (ISSCADA) system patented by scientists with the USDA-Agricultural Research Service (ARS) at Bushland, Texas, incorporates site-specific irrigation scheduling methods informed by weather, plant, and soil water sensing systems. This article introduces a software package, ARSPivot, developed to integrate the ISSCADA system into the operation of VRI center pivot systems. ARSPivot assists the operation and integration of a complex network of sensing systems, irrigation scheduling methods, and irrigation machinery to achieve this end. ARSPivot consists of two independent programs interacting through a client-server architecture. The client program is focused on automatically collecting and processing georeferenced data from sensing systems and communicating with a center pivot control panel, while the server program is focused on communicating with users through a friendly graphical user interface (GUI) involving a geographic information system (GIS). The GUI allows users to visualize and modify site-specific prescription maps automatically generated based on sensor-based irrigation scheduling methods, and to control and monitor the application of irrigation amounts specified in these recommended prescription maps using center pivots equipped for VRI zone control or VRI speed control. This article discusses the principles and design considerations followed in the development of ARSPivot and presents tools implemented in the software for the virtual design and physical operation of a coupled ISSCADA VRI center pivot system. This article also illustrates how the ISSCADA system and ARSPivot constitute a comprehensive sensor-based decision support system (DSS) for VRI management that is accessible to users without in-depth knowledge of sensing systems or irrigation scheduling methods. Keywords: Center pivot irrigation, Decision support system, Precision agriculture, Sensors, Site-specific irrigation scheduling, Software, Variable rate irrigation.n

Background: The emergence and spread of antimicrobial resistance is a major problem in India with significant knowledge on whether this is a systems–based, prescriber and patient characteristic based or diagnostic technologies–based issue. Methods: An electronic survey was sent to select distribution list of intensive care units (ICU) and hospital inpatient (medicine ward) providers from India. Survey questions included antimicrobial clinical practice data, access to electronic medical records, microbiological diagnostic techniques, and access to microbiology data. The survey focused on antimicrobial prescription trends and their association with diagnostic techniques. Results: There were 90 responses from 18 states in 65 ZIP codes. They had median of 187.5 beds (IQR, 40–470). Representative responders had a median age of 40 years (IQR, 31–53). Among the responders, 73 (81%) were men. Of the 90 responses, 48 providers (52%) practiced solely in ICUs (medical and surgical) and 40 providers (45%) practiced solely on the medical ward or floor, with the rest practicing in other units. In total, 31 centers (34%) reported full access to electronic medical records, and 53 centers (59%) had access to wi-fi or Internet. Interestingly, 27 centers (30%) needed to use personal provider phone data for Internet access. Only 26 centers (29%) had electronic microbiological data. Also, 63 respondents (70%) agreed to de-escalation behavior after receiving microbiological data. In addition, 55 respondents (61%) agreed that patients have easy access to outpatient antibiotics without an appropriate prescription, over the counter. Furthermore, 58 responders (64%) said that antibiotic resistance was a major problem at their center, and 61 responders (68%) were familiar with antimicrobial stewardship programs. Among the centers, 69 (77%) had no access to formal infectious disease programs at their center. Only 27 centers (30%) had a formal Clostridium difficile–associated infection reporting and control program. Only 28 centers (31%) had a formal occupational health program. Conclusions: In a large-scale, semistructured, online survey, most issues related to easy availability of antibiotics and lack of “electronization” of medical and microbiological records. It was reassuring that most providers expressed knowledge of the existing antimicrobial stewardship program.Funding: NoneDisclosures: None

The present study investigated the current status of integrating ICT into teaching and learning at Sultan Qaboos University (SQU). A sample of 220 faculty members from six different colleges and four administrators from the Center of Educational Technology (CET) and the Center for Information Systems (CIS) at SQU in Oman were chosen, and quantitative qualitative design using a semi-structured questionnaire, interviews and checklists was employed. The findings show that SQU had a high availability of ICT infrastructure in terms of hardware, software and support services, as well as adequate computer labs for educational purposes. However, the results also indicated that, although SQU provided a series of professional development workshops related to using ICT in teaching, few faculty members were interested. Furthermore, the finding indicated that, the degree of ICT integration into teaching at SQU was at a medium level. Given the importance of ICT integration in teaching and learning, it is recommended that SQU should recognise and acknowledge the faculty members’ role in ICT integration. Therefore, it should provide ways to support faculty members in developing their ICT skills and knowledge and increasing capability in performing their role.

Public health is affected by environmental health. Poor sanitation conditions will have a bad impact on human life, ranging from a decrease in the quality of the community's environment to the pollution of drinking water sources, which can lead to an increase in cases of diarrhea and other diseases. Clean water sources, healthy latrines, and standardized Wastewater Treatment Systems (SPAL) are essential. The purpose of this study is to analyze the relationship between basic sanitation conditions in households and the risk of diarrhea in toddlers. A quantitative method with a cross-sectional design was used in this study to identify the relationship between basic home sanitation, which includes the availability of clean water, the availability of healthy latrines, and the management of SPAL RT, and the possibility of diarrhea in toddlers. In this study, 63 samples of mothers from 74 populations had babies. To get information, questionnaires are distributed. The data were tested with chis-quare, and an error rate of 0.05% was taken into account. The results showed that the availability of clean water had a correlation with the possibility of diarrhea with a P_value of 0.004, the management of household waste sewers had a correlation with P_value 0.008, and the availability of good latrines had no correlation with the possibility of diarrhea with a P_value of 0.262. The results show that the Ujong Fatihah Health Center must continue to make efforts and socialization to increase public knowledge. Health staff must be educated by village officials on the importance of maintaining daily hygiene.

Background and methodology In districts where lymphatic filariasis (LF) is endemic, the goal is to provide 100% geographical coverage of the essential package of care. Additionally, countries seeking elimination status must document the availability of services for lymphoedema and hydrocele in all endemic areas. To do this, the WHO recommends conducting assessments of the readiness and quality of services provided to identify service delivery and quality gaps. This study used the recommended WHO Direct Inspection Protocol (DIP), which consists of 14 core indicators related to LF case management, medicine and commodities, staff knowledge and patient tracking. The survey was administered in 156 health facilities across Ghana designated and trained to provide LF morbidity management services. Patient and health provider interviews were also conducted to assess challenges and feedback. Principal findings The highest performing indicators across the 156 surveyed facilities were related to staff knowledge; 96.6% of health workers correctly identified two or more signs and symptoms. The lowest scoring indicators concerned medication availability, with the two lowest scoring indicators in the survey being availability of antifungals (26.28%) and antiseptics (31.41%). Hospitals performed best with an overall score of 79.9%, followed by health centers (73%), clinics (67.1%) and CHPS compounds (66.8%). The most commonly reported challenge from health worker interviews was lack of medications and supplies, followed by a lack of training or poor motivation. Conclusions and significance The findings from this study can help the Ghana NTD Program identify areas of improvement as they seek to achieve LF elimination targets and continue to improve access to care for those with LF-related morbidity as part of overall health systems strengthening. Key recommendations include prioritizing refresher and MMDP training for health workers, ensuring reliable patient tracking systems, and integrating lymphatic filariasis morbidity management into the routine healthcare system to ensure medicine and commodity availably.

Philosophiae Doctor - PhDHigher education institutions in South Africa have invested heavily in information technology and information systems, with variable outcomes. Organisations in other sectors, such as engineering, the defence industry, public administration and business, have developed and adopted standards and guides to good practice for the development and operation of software-based systems. In the history of standards-making there was an early vision of the need to extend standardisation beyond software engineering into the world that acquires and uses systems, and yet the overall scope of available standards is still limited. Seeing slow progress in the international committees that develop nationally-endorsed standards (such as ISO-IEC/JTC1/SC7) practitioner communities moved to develop good practice guides such as COBIT and ITIL, that have found considerable interest in progressive organisations. Hence a range of potential guidance is available. In order to assess the extent to which standards and good practice guides might assist higher education, the four tertiary institutions in the Western Cape were approached and a representative range of academic, administrative and managerial individuals agreed to contribute to the study as respondents. Interviews were organised in two parts: the first an open conversation about their involvement with systems, and the second a structured examination of systems-related events that they considered significant. By inspection of those events, bipolar scales were developed by which respondents were able to characterise events (for example as ‘challenging’ or ‘easy’, or as ‘functional’ or ‘dysfunctional’). Respondents rated events on those scales. Repertory Grid analysis was applied so as to investigate which scales correlated with event success. 30 scales (out of 170) proved to be adequately correlated with success, and by principal component analysis they were combined to form nine ‘success scale’ groups, indicating nine areas where the deployment of standards or good practice guides might be expected to lead to more effective use of improved information systems. The study adopted an abductive approach to the work, keeping open the question of what might be the contribution to knowledge. In the event, a new Reference Model emerged from the data analysis that contributes to the effective choice and management of standards and good practice guides .A review of available standards and good practice guides using the new Reference Model concludes that the good practice guides are more applicable than the internationally developed standards, and in some areas management models and frameworks have a contribution to make. The utility of standards, good practice guides and management models will depend on the circumstances and context of use, which are extremely variable. A portfolio approach to the management of information systems provides a means to deal with that variability. It is further found that the IMBOK1 can be used to assess the linkages between information technology, information systems, business processes, business benefits and business strategy. The new Reference Model has a role to play in resolving the need for standards in the four junctions between those five IMBOK domains. Selected standards are assessed in that way, and an illustrative commentary is provided showing how projects and other systems-related initiatives can be assessed using the new Reference Model and the IMBOK.

The need for novel diagnostic and therapeutic drugs with the potential to combat increasingly prevalent or particularly insidious diseases has grown in recent years. Concurrently, the issue of translating scientific knowledge from “bench to bedside” has become increasingly salient. In 2011, the U.S. National Institutes of Health created the National Center for Advancing Translational Science in an effort to remedy the recalcitrant gaps between fundamental laboratory research and late-stage clinical trial, thereby dramatically reducing the amount of time and expense needed to develop efficacious pharmaceutical prototypes for a range of emerging, re-emerging, and chronic diseases. However, the realities of pharmaceutical development are incongruous with the expectations of the lay public that even the most fundamental scientific research yield results with immediate social and commercial value. Traditional linear models of progress overlook both the epistemic nature of scientific innovation and the significance of the socio-economic supply and demand factors driving research endeavours.
The aim of this dissertation is to underline the epistemic and socio-economic characteristics of translational science – specifically in the context of research targeting novel oncology therapeutics and diagnostics – through the lens of Science and Technology Studies. In focusing on research in cancer biology funded by the National Center for Advancing Translational Science, this thesis highlights the significance of Mode 2 or “post-academic” science, and by extension the roles of interdisciplinarity and applicability, and the commodification of scientific knowledge, that arise in the process of translating scientific knowledge.Arts, Faculty of

This study explores the implications for knowledge creation of customer knowledge in a contact center’s CRM system. A previously developed research model which depicts CRM systems’ support to knowledge creation of customer knowledge was utilized for evaluation and comparison of collected data. Data was collected through observations semi-structured interviews with 14 customer service agents who utilized a CRM system in a contact center at a medium-sized European airline.Analysis of the data suggests that the CRM system’s support for knowledge creation of customer knowledge is in line with previous research. Additionally, the results indicate that there are two processes, knowledge base usage and internal communication processes, which have the potential to increase the CRM system’s support. Based on the reviewed literature, this study suggests that organizational culture and IT infrastructure, are two tools which could be utilized to incorporate those two processes better into the organization’s CRM system.

It was not long ago. On Christmas Eve 2012, a war of troubleshooting began in Amazon data centers. It started at 12:24 PM, with an mistaken deletion of the state data of Amazon Elastic Load Balancing Service (ELB for short), which was
not realized at that time. The mistake first led to a local issue that a small number of ELB service APIs were affected. In about six minutes, it evolved into a critical one that EC2 customers were significantly affected. One example was that Netflix, which was using hundreds of Amazon ELB services, was experiencing an extensive streaming service outage when many customers could not watch TV shows or movies on Christmas Eve. It took Amazon engineers 5 hours 42 minutes to find the root cause, the mistaken deletion, and another 15 hours and 32 minutes to fully recover the ELB service. The war ended at 8:15 AM the next day and brought the performance
troubleshooting in data centers to world’s attention. As shown in this Amazon ELB case.Troubleshooting runtime performance issues is crucial in time-sensitive multi-tier cloud services because of their stringent end-to-end timing requirements, but it is also notoriously difficult and time consuming.
To address the troubleshooting challenge, this dissertation proposes VScope, a flexible monitoring and analysis system for online troubleshooting in data centers.
VScope provides primitive operations which data center operators can use to troubleshoot various performance issues. Each operation is essentially a series of monitoring and analysis functions executed on an overlay network. We design a novel
software architecture for VScope so that the overlay networks can be generated, executed and terminated automatically, on-demand. From the troubleshooting side, we design novel anomaly detection algorithms and implement them in VScope. By
running anomaly detection algorithms in VScope, data center operators are notified when performance anomalies happen. We also design a graph-based guidance approach, called VFocus, which tracks the interactions among hardware and software components in data centers. VFocus provides primitive operations by which operators can analyze the interactions to find out which components are relevant to the
performance issue.
VScope’s capabilities and performance are evaluated on a testbed with over 1000 virtual machines (VMs). Experimental results show that the VScope runtime negligibly perturbs system and application performance, and requires mere seconds to deploy monitoring and analytics functions on over 1000 nodes. This demonstrates VScope’s ability to support fast operation and online queries against a comprehensive set of application to system/platform level metrics, and a variety of representative analytics functions. When supporting algorithms with high computation complexity, VScope serves as a ‘thin layer’ that occupies no more than 5% of their total latency. Further, by using VFocus, VScope can locate problematic VMs that cannot be found
via solely application-level monitoring, and in one of the use cases explored in the dissertation, it operates with levels of perturbation of over 400% less than what is seen for brute-force and most sampling-based approaches. We also validate VFocus
with real-world data center traces. The experimental results show that VFocus has troubleshooting accuracy of 83% on average.

Cette thèse se positionne dans le cadre de l'algorithmique distribuée tolérante aux pannes adaptée aux réseaux mobiles à grande échelle.L'auto-stabilisation est une approche de tolérance aux pannes satisfaisante dans les systèmes ayant des perturbations transitoires, mais pas dans les réseaux très dynamiques à grande échelle. La faute est due à l'éventuelle absence totale de service lorsque les perturbations sont fréquentes.Pour remédier à cet inconvénient, nous avons introduit l'approche auto-stabilisation robuste apportant une garantie de service pendant la phase de stabilisation.La garantie de service offerte par l'auto-stabilisation robuste est assurée via : (1) le délai de reprise d'un service minimum, et(2) la préservation du service minimum pendant la convergence vers un service optimum en dépit de l'occurrence de certaines perturbations hautement tolérées.L'intérêt d'avoir la propriété auto-stabilisation robuste est d'assurer une haute disponibilité du système en dépit de l'occurrence des perturbations et changements topologiques.Dans cette thèse, nous proposons, prouvons et évaluons une suite protocolaire auto-stabilisante robuste.Dans un premier temps, nous proposons deux protocoles auto-stabilisants robustes pour les problèmes de partitionnement, et l'établissement et le maintien de la connaissance des clusters voisins.Les deux protocoles sont écrits dans le modèle à états et fonctionnent sous l'hypothèse d'un démon distribué faiblement équitable.Le protocole de partitionnement, baptisé R-BSC, permet de partitionner le réseau en clusters à 1-saut. Les noeuds choisis pour être leaders sont les plus aptes à ce rôle, et les clusters construits sont de taille bornée dans le but d'équilibrer la charge entre leaders.Le protocole R-BSC fournit rapidement, en 4 rounds seulement, un service minimum où le réseau est complètement partitionné en clusters de taille bornée.Pendant la convergence vers un service optimum, où les leaders seront bien les noeuds les plus aptes et leur nombre sera réduit localement, le service minimum restera préservé. Le protocole de connaissance des clusters voisins, baptisé R-CNK, permet à chaque leader de connaître l'identité des leaders des clusters voisins, les chemins menant vers eux, ainsi que la composition (liste des noeuds ordinaires) des clusters voisins.Le service minimum de notre protocole R-CNK, atteint après 4 rounds seulement, garantit que tout leader connaît toujours des chemins vers tous les leaders des clusters voisins. Ce service minimum est maintenu en dépit des changements de la structure hiérarchique : création / destruction des clusters, changement de composition des clusters suite au départ / arrivé des noeuds ordinaires.Un deuxième aspect de nos travaux concerne l'évaluation des protocoles conçus (R-BSC et R-CNK) dans le contexte des réseaux mobiles.Nous avons mené une étude expérimentale sous le simulateur NS2 pour évaluer les performances de nos protocoles, ainsi que ceux des protocoles auto-stabilisants correspondants.Cette étude a montré que nos protocoles R-BSC et R-CNK offrent de meilleurs performances en terme de garantie de service, d'où l'efficacité de l'approche auto-stabilisation robuste par rapport à l'auto-stabilisation classiqueThis dissertation is focused on fault-tolerant distributed algorithms adapted to large scale mobile networks.Self-stabilization is a fault-tolerance approach suited for systems with transient disruptions, but not for large scale dynamic networks.The fault is due to the eventual total lack of service when faults occur frequently.To address this drawback, we have introduced the robust self-stabilization approach that improves the service guarantee during the stabilization phase.The service guarantee provided by the robust self-stabilization is achieved via:(1) fast recovery to a minimum service and(2) preservation of minimum service during the convergence to an optimum service despite the occurrence of highly tolerated disruptions.Having the robust self-stabilization property ensures a high availability of the system despite the occurrence disruptions and topological changes in the network.In this thesis, we propose, evaluate and prove a series of robust self-stabilizing protocols.At first, we propose two robust self-stabilizing protocols for both problems : clustering and the maintain of knowledge about neighbor clusters.The two protocols are written in the local shared memory model and operate under the assumption of a weakly fair distributed daemon.The clustering protocol, called R-BSC, gathers the network nodes into 1-hop clusters.It allows a best choice of leaders, and it builds clusters with limited size in order to balance the load between leaders.The protocol R-BSC quickly provides, after at most 4 rounds, a minimum service where the network is completely partitioned into bounded-size clusters.During the convergence towards an optimum service, in which leaders will be the most appropriate nodes and their number will be reduced locally, the minimum service is preserved.The protocol for knowledge of neighbor clusters, called R-CNK, allows each leader to know the identity of leaders of neighbor clusters, paths leading to them, and the composition (list of ordinary nodes) of its neighbor clusters.The minimum service provided by of R-CNK protocol, reached after 4 rounds, ensures that every leader always knows paths towards all the leaders of neighbor clusters.We conducted an experimental study using the simulator NS2 to evaluate and to compare the performance of our protocols (R-BSC and R-CNK) with those of their self-stabilizing version in the context of mobile networks.This study confirmed that our protocols R-BSC and R-CNK offer a better service guarantee

Sur la base d’une étude historique des rapports entre les cycles techno-économiques du système mondial et le processus de transformation économique, politique et idéologique d’un pays périphérique comme l’Équateur, cette recherche présente une analyse critique sur le processus de développement du champ technoscientifique de ce pays et le projet de modernisation postnéolibéral mis en place par son gouvernement entre 2007-2017. L’exposition est organisée en deux parties. La première analyse les rapports entre les transformations techno-économiques mondiales et les cycles économiques et politiques locaux ; les rapports entre ces cycles, les vagues de modernisation du système d’éducation supérieure équatorien et la reproduction des élites locales ; et enfin, les rapports entre ces deux derniers et le processus de développement scientifique, technologique et industriel du pays. La deuxième partie est consacrée à l'étude en détail du dernier de ces cycles, caractérisé par la mise en place du projet postnéolibéral de modernisation technoscientifique. Cette étude se focalise particulièrement sur trois projets : la réforme de l’éducation supérieure, le programme de bourses d’étude à l’étranger et le projet de construction de Yachay, une ville dédiée à la science, à la technologie et à l’innovation. Les résultats de ces analyses dévoilent le caractère idéologique de ces projets, conçus et dirigés par un même réseau d’intellectuels et financés par l’essor des exportations de matières premières qui a accompagné cette phase ascendante du cycle périphérique. Enfermés dans leur quête idéologique d’un modèle de développement alternatif et les contraintes imposées par les processus de transformation du système mondial, ces acteurs ont fini par produire un projet de modernisation contradictoire basé sur une abstraction empirique adaptée à leurs besoins de légitimation politique. La fin de l’essor économique a dévoilé les limites de ce projet idéologique dont les résultats concrets sont une plus lourde bureaucratie, le gaspillage des ressources publiques et l’accumulation de pouvoir. Nous suggérons que ce résultat est un effet du décalage entre les cycles de transformation à la périphérie et au centre du système mondial et du processus de reconfiguration global liée à la montée de l’influence chinoise et au déploiement de la dernière vague de transformations techno-économiques. Cette recherchée s’inscrit ainsi dans la lignée de réflexion sur les transformations du système mondialBased on a historical study of the relationship between the techno-economic cycles of the global system and the economic, political and ideological transformations in Ecuador, this research presents a critical analysis of the development process of the technoscientific field in this country and the post-neoliberal modernization project implemented by its government between 2007-2017. The thesis has two parts. The first one develops an analysis on three levels: the relationships between the global techno-economic cycles and the political and economic transformations in Ecuador; the relationships between these transformations, the waves of modernization of the Ecuadorian higher education system and the reproduction of local elites; and the relationship between the latter and the scientific, technological and industrial development of the country. The second part presents a detailed study of the last cycle, characterized by the implementation of the post-neoliberal project of technoscientific modernization. This study focuses, particularly, on three projects: the higher education reform, the scholarship program for studies abroad and the Yachay technopole project. These analysis results reveal the ideological character of these projects, designed and directed by the same network of intellectuals and financed by the rise of commodity exports which accompanied this upward phase of the peripheral cycle. Trapped in their ideological quest for an alternative development model and the constraints imposed by the transformation processes of the global system, these actors have finally produced a contradictory modernization project based on an empirical abstraction adapted to their needs for political legitimization. The end of the economic upswing has unveiled the limits of this ideological project whose concrete results are a heavier bureaucracy, waste of public resources and the accumulation of power. We suggest that this result is an effect of the three interrelated processes: the gap between the transformation cycles at the periphery and at the center of the global system, the global reconfiguration linked to the rise of Chinese influence and the deployment of the latest techno-economic wave of innovation. This research aims thus to contribute to the debate on the historical transformations of the global system

Engaging Queensland primary teachers in professional associations can be a challenge, particularly for subject-specific associations. Professional associations are recognised providers of professional learning. By not being involved in professional associations primary teachers are missing potential quality professional learning opportunities that can impact the results of their students. The purpose of the research is twofold: Firstly, to provide a thorough understanding of the current context in order to assist professional associations who wish to change from their current level of primary teacher engagement; and secondly, to contribute to the literature in the area of professional learning for primary teachers within professional associations. Using a three part research design, interviews of primary teachers and focus groups of professional association participants and executives were conducted and themed to examine the current context of engagement. Force field analysis was used to provide the framework to identify the driving and restraining forces for primary teacher engagement in professional learning through professional associations. Communities of practice and professional learning communities were specifically examined as potential models for professional associations to consider. The outcome is a diagrammatic framework outlining the current context of primary teacher engagement, specifically the driving and restraining forces of primary teacher engagement with professional associations. This research also identifies considerations for professional associations wishing to change their level of primary teacher engagement. The results of this research show that there are key themes that provide maximum impact if wishing to increase engagement of primary teachers in professional associations. However the implications of this lies with professional associations and their alignment between intent and practice dedicated to this change.

The increasing demand for storage and computation has driven the growth of large data centers—the massive server farms that run many of today's Internet and business applications. A data center can comprise many thousands of servers and can use as much energy as a small city. The massive amounts of computation power contained in these systems results in many interesting distributed systems and resource management problems. In this thesis we investigate challenges related to data centers, with a particular emphasis on how new virtualization technologies can be used to simplify deployment, improve resource efficiency, and reduce the cost of reliability, all in application agnostic ways. We first study problems that relate to the initial capacity planning required when deploying applications into a virtualized data center. We demonstrate how models of virtualization overheads can be utilized to accurately predict the resource needs of virtualized applications, allowing them to be smoothly transitioned into a data center. We next study how memory similarity can be used to guide placement when adding virtual machines to a data center, and demonstrate how memory sharing can be exploited to reduce the memory footprints of virtual machines. This allows for better server consolidation, reducing hardware and energy costs within the data center. We then discuss how virtualization can be used to improve the performance and efficiency of data centers through the use of “live” migration and dynamic resource allocation. We present automated, dynamic provisioning schemes that can effectively respond to the rapid fluctuations of Internet workloads without hurting application performance. We then extend these migration tools to support seamlessly moving applications across low bandwidth Internet links. Finally, we discuss the reliability challenges faced by data centers and present a new replication technique that allows cloud computing platforms to offer high performance, no data loss disaster recovery services despite high network latencies.

Record keeping is not a static way to document history but rather a way for people in the present to engage with, and be affected by, the past. This is especially true in the case of online databases. Databases store information but their use also encourages the adoption of specific methodologies for apprehending reality because it is through those methodological agreements that the information in the database becomes relevant. In the summer of 2012 I spent four months observing and interviewing wheat researchers and database developers at a major agricultural research center in Mexico as part of my M.A. thesis project. This paper argues that people using the International Wheat Information System (IWIS) database at the International Maize and Wheat Improvement Center (CIMMYT) are involved in a process that documents wheat pedigree information while also enacting a reality based on assumptions about the value of certain types of human pedigree.

Economists and social scientists are increasingly making use of web data to address socio-economic issues and to integrate existing sources of information. The data produced by online platforms and websites could produce a lot of useful and multidimensional information with a variety of potential applications in socio-economic analysis. In this respect, with the internet growth and knowledge, many aspects of job search have been transformed due to the availability of online tools for job searching, candidate searching and job matching. In European countries there is growing interest in designing and implementing real labour market information system applications for internet labour market data in order to support policy design and evaluation through evidence-based decision-making. The analysis of labour market web data could provide useful information for policy-makers to define labour market strategies as big data, jointly with official statistics, support policy makers in a pressing policy question namely “How to tackle the mismatch between jobs and skills?”. In this regard, the topic of skills gap, how to measure it and how to bridge it with education and continuous training have been tackled by using the big data collection, such as the Cedefop (European Center for the Development of Vocational Training) initiative and the Wollybi Project (made by Burning Glass). In this framework, this contribution focuses on the issues arising from the use (and the usefulness) of on-line job vacancy data to analyse the Italian labour market by using the Wollybi data available for the years 2019 and 2020. Furthermore, the availability of data for the year 2020, will allow us to evaluate whether there has been an impact of COVID19 in terms of needed skills and required occupations in the online job vacancies.

ABSTRACT Background: Community health center (puskesmas) management information system or often referred to as SIMPUS is a local health system aimed at providing health information at primary health care level. This health information systems have been implemented in many districts. However, their performance is yet to be improved caused by several factors such as a lack of human resources and hardware. This study aimed to investigate factors associated with implementation of health information management in community health centers. Subjects and Method: This was a systematic review by collecting published articles in open-access journals and proceedings from Directory of Open Access Journal, Elsevier, and Google scholar databases. “Health information system”, “implementation health information system”, and “evaluation health information system” were used as key findings. The selected articles were reviewed by meta-aggregate. Results: Previous studies reported that implementation of health information management in community health center faced several barriers, including (1) incomplete data, and (2) low monitoring and safety control. To implement health information management properly, the following components need to be fulfilled: (1) infrastructure availability (software, hardware, data safety, and internet network speed), (2) human source (user knowledge, experience, skill, accuracy), and (3) funds. Conclusion: Implementation of health information management in community health center is affected by infrastructure availability, internet network speed, user knowledge and experience, and funds.

Successfully fulfilling customers’ needs with world class products whilst remaining competitive and profitable are a major driver for the aerospace industry. The 21st Century is placing ever increasing pressure upon manufacturers to deliver high complexity, technologically enabled products to instantaneously fulfill a desired purpose at the point of use. To meet such stringent criteria, companies must find ways to continuously improve, reduce waste and accelerate the product development process whilst innovating. This paper presents a multiple case study approach of turbine blade manufacturing part families which has been used to further develop a manufacturing knowledge reuse method that is being developed in partnership with a high tech aerospace company for application within a PLM environment. This method is currently being explored within the company so as to accelerate the design-make process to enable earlier availability of, and easier access to, manufacturing knowledge, thus bringing about better product performance. The contents of the paper presents a methodical approach to the study of a number of products in an effort to ascertain how the complex interrelationships between design knowledge and manufacturing knowledge change across part families and, consequently, how they affect a developed feature knowledge relationship structure (FKRS) that maps design, manufacture and inspection viewpoints of product knowledge. Utilizing the FKRS, a pragmatic way has been developed in which people-to-people knowledge can be captured and shared to facilitate a reduction in the associated lead-time for information and knowledge retrieval and reuse. For this to be more widely applicable to different types of turbine blade it is necessary to widen the scope of the research. Four case studies are presented showing the aspects that constitute a part family and how knowledge varies across the products being studied. The FKRS is applied to the captured manufacturing knowledge in an effort to prove that it can represent and model multi-context knowledge across part families. The results have shown that the approach provides a basis for the representation of complex relationship viewpoints for product features and is valid for a number of manufacturing part families.

Siemens Power Diagnostics® Services is designed to maximize plant performance, availability and profitability. Engineering knowledge, combined with the use of sophisticated tools, provides trending and analysis capabilities to address a broad range of operating needs specific to each customer. The goal of Power Diagnostics® is to enhance Siemens assistance to our customers through the detection of impending operational problems thereby helping to minimize unplanned outages and maximize power generation availability. A variety of new technologies are being harnessed to further this goal. A survey and discussion of these technologies will be the goal of this paper. Some of the projects discussed will be; Advances in the Power Plant Automated Diagnostics Systems, Blade Vibration Monitor (BVM), Fiber Optic Vibration Monitor (FOVM), and the Radio Frequency Monitor (RFM). The development and verification phases of research projects have often been conducted at customer sites. Many aspects of these technologies are new and will be of interest to gas turbine engineers as they are not widely applied yet. It is hoped that the reader will gain a new appreciation for the scope of modern diagnostic methods for power generation systems.

The use of best practices and their lateral expansion as a benchmark is one of effective methods of “knowledge management (NK)”. Best practices of human resources development were collected (selected examples are listed below) from all 11 training centers annexed to the nuclear power plants in Japan and lessons were learned for possible lateral development for improving other stakeholders’ NK. Such best practices will provide productive information for designing their own human resources development strategies. Examples of collected good practices: • Exhibition of troubles and negative legacies: The actual machineries, equipment or components, explanatory documents or news articles of the past troubles experienced by themselves are effective to maintain and refresh the awareness and preparedness of trainees and other employees for recurrence prevention. The exhibitions are open to the visitors, too. • Experience-type training facilities: Off-normal conditions of components and systems are simulated for the staff practical training by the use of the facilities which provide an off-normal environment. Examples are: water hammers, abnormal vibrations and noises of rotating machineries, pump cavitations, pinholes, plumbing airs, etc. • Advanced simulators for operators training: Each electric company has its own simulators for training their own operating staff. These simulators are annexed to the nuclear power plants and used to train the operation staff by the experienced shift managers. The operation staff use the simulator for continually confirming the operation procedures and the plant behavior, etc. specific to their plants. Training for generic plant behavior and operators’ responses are mainly outsourced to the dedicated training centers run by the Owners’ Groups (BWR, PWR). • The SAT methods: The IAEA proposed SAT (Systematic Approach to Training) approach is applied to the training of the operating staff and the maintenance staff. It is structured in a flow of Job analysis ← Training program design ← Training material development ← Training ← Evaluation. • Training in real situations: An example is a trainee actually hung with a lifeline on a harness to learn a method of putting on the lifeline. On the other hand, the efficiency (availability) of the training facilities for maintenance work is very limited, because each electric company installs the training facilities individually. Experiences of ICONE-16 participants from other countries in improving the availability are of our interest.

Floods are major water-related disasters that affect millions of people resulting in thousands of mortalities and billiondollar losses globally every year. Flood Early Warning Systems (FEWS) - one of the floods risk management measures - are currently operational in many countries. The UN Office for Disaster Risk Reduction recognises their importance and strongly advocates for an increase in their availability under the targets of the Sendai Framework for Disaster Risk Reduction, and Sustainable Development Goals (SDGs). However, despite widespread recognition of the importance of FEWS for disaster risk reduction (DRR), there’s a lack of information on their availability and status around the world, their benefits and costs, challenges and trends associated with their development. This report contributes to bridging these gaps by analyzing the responses to a comprehensive online survey with over 80 questions on various components of FEWS (risk knowledge, monitoring and forecasting, warning dissemination and communication, and response capabilities), investments into FEWS, their operational effectiveness, benefits, and challenges. FEWS were classified as technologically “basic”, “intermediate” and “advanced” depending on the existence and sophistication of FEWS` components such as hydrological data = collection systems, data transfer systems, flood forecasting methods, and early warning communication methods. The survey questionnaire was distributed to flood forecasting and warning centers around the globe; the primary focus was developing and least-developed countries (LDCs). The questionnaire is available here: https://inweh.unu.edu/questionnaireevaluation-of-flood-early-warning-systems/ and can be useful in its own right for similar studies at national or regional scales, in its current form or with case-specific modifications. Survey responses were received from 47 developing (including LDCs) and six developed countries. Additional information for some countries was extracted from available literature. Analysis of these data suggests the existence of an equal number of “intermediate” and “advanced” FEWS in surveyed river basins. While developing countries overall appear to progress well in FEWS implementation, LDCs are still lagging behind since most of them have “basic” FEWS. The difference between types of operational systems in developing and developed countries appear to be insignificant; presence of basic, intermediate or advanced FEWS depends on available investments for system developments and continuous financing for their operations, and there is evidence of more financial support — on the order of USD 100 million — to FEWS in developing countries thanks to international aid. However, training the staff and maintaining the FEWS for long-term operations are challenging. About 75% of responses indicate that river basins have inadequate hydrological network coverage and back-up equipment. Almost half of the responders indicated that their models are not advanced and accurate enough to produce reliable forecasts. Lack of technical expertise and limited skilled manpower to perform forecasts was cited by 50% of respondents. The primary reason for establishing FEWS, based on the survey, is to avoid property damage; minimizing causalities and agricultural losses appear to be secondary reasons. The range of the community benefited by FEWS varies, but 55% of FEWS operate in the range between 100,000 to 1 million of population. The number of flood disasters and their causalities has declined since the year 2000, while 50% of currently operating FEWS were established over the same period. This decline may be attributed to the combined DRR efforts, of which FEWS are an integral part. In lower-middle-income and low-income countries, economic losses due to flood disasters may be smaller in absolute terms, but they represent a higher percentage of such countries’ GDP. In high-income countries, higher flood-related losses accounted for a small percentage of their GDP. To improve global knowledge on FEWS status and implementation in the context of Sendai Framework and SDGs, the report’s recommendations include: i) coordinate global investments in FEWS development and standardise investment reporting; ii) establish an international hub to monitor the status of FEWS in collaboration with the national responsible agencies. This will support the sharing of FEWS-related information for accelerated global progress in DRR; iii) develop a comprehensive, index-based ranking system for FEWS according to their effectiveness in flood disaster mitigation. This will provide clear standards and a roadmap for improving FEWS’ effectiveness, and iv) improve coordination between institutions responsible for flood forecasting and those responsible for communicating warnings and community preparedness and awareness.

Faced with environmental degradation and strong land pressure, farmers in south-central Niger have intensified their agricultural production systems. Since the 1980s, farmers in the regions of Zinder, Maradi and Tahoua have increased the number of trees and shrubs on their fields, creating new agroforestry parklands over about 5 million hectares. This regreening is not based on tree planting, however, but on farmers protecting and managing natural regeneration of woody species on their crop lands. This has been well documented over the years, but until now, there has not been a thorough review of all of the published peer-referenced as well as grey literature. This report presents the first comprehensive state of knowledge of farmer managed natural regeneration (FMNR) in Niger. Studies show the scale and dynamics of FMNR as well as its multiple impacts. It has increased crop yields (+31 kg/ha to +350 kg/ha), and that supports family food security even in drought years. FMNR has increased the income of all social categories, even the most vulnerable women, men and youth, through the sale of fuelwood and service wood. The pruning of trees in fields has also reduced the distances travelled by women to collect fuelwood. FMNR increased the availability of fodder from trees to farmers and agropastoralists, with households practising FMNR harvesting 30-45 kg of fodder per day. Economists have not calculated all the multiple impacts in monetary terms, but studies on the costs and benefits all indicate that it is economically rational for farmers to invest their labour in FMNR. The costs are modest (no equipment and little labour), and the benefits are substantial, also helping smallholder farmers adapt to climate change, while sequestering millions of tonnes carbon. As a consequence of FMNR, tree cover has been sustained without external incentives (e.g. food or cash-for-work), an outcome that distinguishes this farmer-driven practice from large-scale tree planting projects where farmers’ stewardship ended when the external incentives ended. Agroforestry landscapes are thus being created at scale due to decisions made by hundreds of thousands of individual farmers. It is hoped that information in this report that shows the clear benefits of FMNR in Niger will encourage policy makers in Africa’s drylands to invest in the promotion of FMNR. This foundational practice must form the backbone of landscape wide initiatives if the ambitious targets of the Great Green Wall, AFR100 and similar ambitious restoration initiatives are to be achieved. FMNR is a low cost sustainable land use management practice with a considerable potential for scaling, which can and must be adopted and scaled immediately.

Increasing food self-sufficiency means rethinking global supply chains, (re-)adapting to local contexts, and ensuring optimal conditions for selling and buying locally produced food. Increased self-sufficiency and improved local food systems can have positive environmental, social, and economic consequences. However, whether increased self-sufficiency adds to more sustainable food systems depends on myriad factors, including production methods, the type of food in question, and the availability of local food on the local market. Previous research shows that local food production does not automatically equate to sustainable food production. This project sought to increase knowledge of how greater food self-sufficiency can contribute to increased sustainability and resilience in the food systems of five Nordic island societies: Bornholm, the Faroe Islands, Greenland, Iceland, and Åland.

Under the United States Department of Homeland Security (DHS) Assistance to Firefighter Grant Fire Prevention and Safety Research Program, Underwriters Laboratories examined fire service concerns of photovoltaic (PV) systems. These concerns include firefighter vulnerability to electrical and casualty hazards when mitigating a fire involving photovoltaic (PV) modules systems. The need for this project is significant acknowledging the increasing use of photovoltaic systems, growing at a rate of 30% annually. As a result of greater utilization, traditional firefighter tactics for suppression, ventilation and overhaul have been complicated, leaving firefighters vulnerable to potentially unrecognized exposure. Though the electrical and fire hazards associated with electrical generation and distribution systems is well known, PV systems present unique safety considerations. A very limited body of knowledge and insufficient data exists to understand the risks to the extent that the fire service has been unable to develop safety solutions and respond in a safe manner. This fire research project developed the empirical data that is needed to quantify the hazards associated with PV installations. This data provides the foundation to modify current or develop new firefighting practices to reduce firefighter death and injury. A functioning PV array was constructed at Underwriters Laboratories in Northbrook, IL to serve as a test fixture. The main test array consisted of 26 PV framed modules rated 230 W each (5980 W total rated power). Multiple experiments were conducted to investigate the efficacy of power isolation techniques and the potential hazard from contact of typical firefighter tools with live electrical PV components. Existing fire test fixtures located at the Delaware County Emergency Services Training Center were modified to construct full scale representations of roof mounted PV systems. PV arrays were mounted above Class A roofs supported by wood trusses. Two series of experiments were conducted. The first series represented a room of content fire, extending into the attic space, breaching the roof and resulting in structural collapse. Three PV technologies were subjected to this fire condition – rack mounted metal framed, glass on polymer modules, building integrated PV shingles, and a flexible laminate attached to a standing metal seam roof. A second series of experiments was conducted on the metal frame technology. These experiments represented two fire scenarios, a room of content fire venting from a window and the ignition of debris accumulation under the array. The results of these experiments provide a technical basis for the fire service to examine their equipment, tactics, standard operating procedures and training content. Several tactical considerations were developed utilizing the data from the experiments to provide specific examples of potential electrical shock hazard from PV installations during and after a fire event.

The antibotulinal baceriocins, propionicin PLG-1 and jenseniin G., were the first to be identified, purified and characterized for the dairy propionibaceria and are produced by Propionibacterium thoenii P127 and P. thoenii/jensenii P126, respectively. Objectives of this project were to (a) produce polyclonal antibodies for detection, comparison and monitoring of propionicin PLG-1; (b) identify, clone and characterize the propionicin PLG-1 (plg-1) and jenseniin G (jnG) genes; and (3) develop gene transfer systems for dairy propionibacteria using them as models. Polyclonal antibodies for detection, comparison and monitoring of propionicin PLG-1 were produced in rabbits. Anti-PLG-1 antiserum had high titers (256,000 to 512,000), neutralized PLG-1 activity, and detected purified PLG-1 at 0.10 mg/ml (indirect ELISA) and 0.033 mg/ml (competitive indirect ELISA). Thirty-nine of 158 strains (most P. thoenii or P. jensenii) yielded cross-reacting material; four strains of P. thoenii, including two previously unidentified bacteriocin producers, showed biological activity. Eight propionicin-negative P127 mutants produced neither ELISA response nor biological activity. Western blot analyses of supernates detected a PLG-1 band at 9.1 kDa and two additional protein bands with apparent molecular weights of 16.2 and 27.5 kDa. PLG-1 polyclonal antibodies were used for detection of jenseniin G. PLG-1 antibodies neutralized jenseniin G activity and detected a jenseniin G-sized, 3.5 kDa peptide. Preliminary immunoprecipitation of crude preparations with PLG-1 antibodies yielded three proteins including an active 3-4 kDa band. Propionicin PLG-1 antibodies were used to screen a P. jensenii/thoenii P126 genomic expression library. Complete sequencing of a cloned insert identified by PLG-1 antibodies revealed a putative response regulator, transport protein, transmembrane protein and an open reading frame (ORF) potentially encoding jenseniin G. PCR cloning of the putative plg-1 gene yielded a 1,100 bp fragment with a 355 bp ORF encoding 118 amino acids; the deduced N-terminus was similar to the known PLG-1 N-terminus. The 118 amino acid sequence deduced from the putative plg-1 gene was larger than PLG-1 possibly due to post-translational processing. The product of the putative plg-1 gene had a calculated molecular weight of 12.8 kDa, a pI of 11.7, 14 negatively charged residues (Asp+Glu) and 24 positively charged residues (Arg+Lys). The putative plg-1 gene was expressed as an inducible fusion protein with a six-histidine residue tag. Metal affinity chromatography of the fused protein yielded a homogeneous product. The fused purified protein sequence matched the deduced putative plg-1 gene sequence. The data preliminarily suggest that both the plg-1 and jnG genes have been identified and cloned. Demonstrating that antibodies can be produced for propionicin PLG-1 and that those antibodies can be used to detect, monitor and compare activity throughout growth and purification was an important step towards monitoring PLG-1 concentrations in food systems. The unexpected but fortunate cross-reactivity of PLG-1 antibodies with jenseniin G led to selective recovery of jenseniin G by immunoprecipitation. Further refinement of this separation technique could lead to powerful affinity methods for rapid, specific separation of the two bacteriocins and thus facilitate their availability for industrial or pharmaceutical uses. Preliminary identification of genes encoding the two dairy propionibacteria bacteriocins must be confirmed; further analysis will provide means for understanding how they work, for increasing their production and for manipulating the peptides to increase their target species. Further development of these systems would contribute to basic knowledge about dairy propionibacteria and has potential for improving other industrially significant characteristics.

The performance of supply chains used to be mainly the concern of academics and professionals who studied the potential efficiencies and risks associated with this aspect of globalisation. In 2021, major disruptions in this critical sector of our economies are making headlines and attracting the attention of policy makers around the world. Supply chain bottlenecks create shortages, fuel inflation, and undermine economic recovery. This report provides a transversal and multidisciplinary analysis of the challenges and opportunities regarding data interoperability and data sharing as they relate to the ‘Great Lakes - St. Lawrence Seaway Trade Corridor’ (GLSLTC)’s intermodal transportation and trade data strategy. The size and scope of this trade corridor are only matched by the complexity of its multimodal freight transportation systems and growing urbanization on both sides of the Canada-US border. This complexity is exacerbated by the lack of data interoperability and effective collaborations between the different stakeholders within the various jurisdictions and amongst them. Our analytical work relies on : 1) A review of the relevant documentation on the latest challenges to supply chains (SC), intermodal freight transport and international trade, identifying any databases that are to be used.; 2) A comparative review of selected relevant initiatives to give insights into the best practices in digital supply chains implemented in Canada, the United States, and the European Union.; 3) Interviews and discussions with experts from Transport Canada, Statistics Canada, the Canadian Centre on Transportation Data (CCTD) and Global Affairs Canada, as well as with CIRANO’s research community and four partner institutions to identify databases and data that they use in their research related to transportation and trade relevant data availabilities and methodologies as well as joint research opportunities. Its main findings can be summarized as follow: GLSLTC is characterized by its critical scale, complexity, and strategic impact as North America’s most vital trade corridor in the foreseeable further intensification of continental trade. 4% of Canadian GDP is attributed to the Transportation and Logistics sector (2018): $1 trillion of goods moved every year: Goods and services imports are equivalent to 33% of Canada’s GDP and goods and services exports equivalent to 32%. The transportation sector is a key contributor to the achievement of net-zero emissions commitment by 2050. All sectors of the Canadian economy are affected by global supply chain disruptions. Uncertainty and threats extend well beyond the COVID-19 Pandemic. “De-globalization” and increasing supply chains regionalization pressures are mounting. Innovation and thus economic performance—increasingly hinges on the quantity and quality of data. Data is transforming Canada’s economy/society and is now at the center of global trade “Transport data is becoming less available: Canada needs to make data a priority for a national transportation strategy.” * “How the Government of Canada collects, manages, and governs data—and how it accesses and shares data with other governments, sectors, and Canadians—must change.”

Indonesia is facing a learning crisis. While schooling has increased dramatically in the last 30 years, the quality of education has remained mediocre (Rosser et al., 2022). Teacher capability is an often cited weakness of the system, along with policies and system governance. Approaches focused primarily on adding resources to education have not yielded expected outcomes of increased quality. “It is a tragedy that in the second decade of the twenty-first century, some children in Indonesia are not completing primary school and are turned out into the workforce as functional illiterates.” (Suryadarma and Jones, 2013; Nihayah et al., 2020). In the early 2000s, Indonesia began a process of decentralising service delivery, including education, to the district level. Many responsibilities were transferred from the central government to districts, but some key authorities, such as hiring of civil service teachers, remained with the central government. The Indonesian system is complex and challenging to manage, with more than 300 ethnic groups and networks of authority spread over more than 500 administrative districts (Suryadarma and Jones, 2013). Niken Rarasati and Daniel Suryadarma researchers at SMERU, an Indonesian think tank and NGO, understood this context well. Their prior experience working in the education sector had shown them that improving the quality of education within the classroom required addressing issues at the systems level (Kleden, 2020). Rarasati noted the difference in knowledge between in-classroom teaching and the systems of education: “There are known-technologies, pedagogical theories, practices, etc. for teaching in the classroom. The context [for systems of education] is different for teacher development, recruitment, and student enrollment. Here, there is less known in the public and education sector.” Looking for ways to bring changes to policy implementation and develop capabilities at the district level, SMERU researchers began to apply a new approach they had learned in a free online course offered by the Building State Capability programme at the Center for International Development at Harvard University titled, “The Practice of PDIA: Building Capability by Delivering Results”. The course offered insights on how to implement public policy in complex settings, focused on using Problem Driven Iterative Adaptation (PDIA). The researchers were interested in putting PDIA into practice and seeing if it could be an effective approach for their colleagues in government. This case study reviews Rarasati and Suryadarma’s journey and showcases how they used PDIA to foster relationships between local government and stakeholders, and bring positive changes to the education sector.

A growing number of states are launching community school initiatives to ensure family and community engagement, provide enriched and expanded learning, and offer integrated supports for students. This brief offers examples from the National Center for Community Schools and from New York, New Mexico, and California showing how technical assistance can build capacity through consultation, training, coaching, and knowledge building. These examples indicate the ways that states are designing technical assistance (TA) systems to support practitioners, the value of providing differentiated TA supports, and the impact of cross-sector partnerships on TA provision.
