Theoretical Considerations

This paper presents a survey of innovative concepts and technologies involved in virtual museums (ViM) that shows their advantages and disadvantages in comparison with physical museums. We describe important lessons learned during the creation of three major virtual museums between 2010 and 2020 with partners at universities from Armenia, Germany, and Chile. Based on their categories and features, we distinguish between content-, communication- and collaboration-centric museums with a special focus on learning and co-curation. We give an overview of a generative approach to ViMs using the ViMCOX metadata format, the curator software suite ViMEDEAS, and a comprehensive validation and verification management. Theoretical considerations include exhibition design and new room concepts, positioning objects in their context, artwork authenticity, digital instances and rights management, distributed items, private museum and universal access, immersion, and tour and interaction design for people of all ages. As a result, this survey identifies different approaches and advocates for stakeholders’ collaboration throughout the life cycle in determining the ViM's direction and evolution, its concepts, collection type, and the technologies used with their requirements and evaluation methods. The paper ends with a brief perspective on the use of artificial intelligence in ViMs.

The Status

The natural conditions, climate change and socio-economic challenges related to the transformation from a socialistic society towards a market-driven system make the implementation of sustainable land management practices in Mongolia especially complicated. Forests play an important role in land management. In addition to providing resources and ecosystem functions, Mongolian forests protect against land degradation.We conducted a literature review of the status of forest management in Mongolia and lessons learned, with special consideration to halting deforestation and degradation. We grouped our review into seven challenges relevant to developing regionally adapted forest management systems that both safeguard forest health and consider socio-economic needs. In our review, we found that current forest management in Mongolia is not always sustainable, and that some practices lack scientific grounding. An overwhelming number of sources noticed a decrease in forest area and quality during the last decades, although afforestation initiatives are reported to have increased. We found that they have had, with few exceptions, only limited success. During our review, however, we found a number of case studies that presented or proposed promising approaches to (re-)establishing and managing forests. These studies are further supported by a body of literature that examines how forest administration, and local participation can be modified to better support sustainable forestry. Based on our review, we conclude that it is necessary to integrate capacity development and forest research into holistic initiatives. A special focus should be given to the linkages between vegetation cover and the hydrological regime.

Longitudinal Imaging

Non-invasive longitudinal imaging of osseointegration of bone implants is essential to ensure a comprehensive, physical and biochemical understanding of the processes related to a successful implant integration and its long-term clinical outcome. This study critically reviews the present imaging techniques that may play a role to assess the initial stability, bone quality and quantity, associated tissue remodelling dependent on implanted material, implantation site (surrounding tissues and placement depth), and biomarkers that may be targeted. An updated list of biodegradable implant materials that have been reported in the literature, from metal, polymer and ceramic categories, is provided with reference to the use of specific imaging modalities (computed tomography, positron emission tomography, ultrasound, photoacoustic and magnetic resonance imaging) suitable for longitudinal and non-invasive imaging in humans. The advantages and disadvantages of the single imaging modality are discussed with a special focus on preclinical imaging for biodegradable implant research. Indeed, the investigation of a new implant commonly requires histological examination, which is invasive and does not allow longitudinal studies, thus requiring a large number of animals for preclinical testing. For this reason, an update of the multimodal and multi-parametric imaging capabilities will be here presented with a specific focus on modern biomaterial research.

This concluding chapter draws together lessons learned from the encounters between social economy activists and academics from Latin America and Europe which were brought together in this collection. It discusses the role of antagonism in social economies, especially in the light of austerity in Europe – and Latin America’s experiences of a lost decade. It discusses tensions between the benefits of top down, centralised, state delivered welfare, and grassroots creativity, arguing for the development of 45 degree politics that maintains the best of both conceptions, with the state maintaining universal access and sufficient resources, while grassroots actors ensure that initiatives are tailored to local needs. Finally it brings together arguments for the need for the SSE sector to develop conceptions of prosperous livelihoods providing dignity and inclusion for those currently denied a livelihood with dignity in the concept of the Anthropocene. It concludes by arguing that these conceptions can best be developed though continued dialogue between actors in the global North and South.

Purpose Models of integrated care are prime examples of complex interventions, incorporating multiple interacting components that work through varying mechanisms to impact numerous outcomes. The purpose of this paper is to explore summative, process and developmental approaches to evaluating complex interventions to determine how to best test this mess. Design/methodology/approach This viewpoint draws on the evaluation and complex intervention literatures to describe the advantages and disadvantages of different methods. The evaluation of the electronic patient reported outcomes (ePRO) mobile application and portal system is presented as an example of how to evaluate complex interventions with critical lessons learned from this ongoing study. Findings Although favored in the literature, summative and process evaluations rest on two problematic assumptions: it is possible to clearly identify stable mechanisms of action; and intervention fidelity can be maximized in order to control for contextual influences. Complex interventions continually adapt to local contexts, making stability and fidelity unlikely. Developmental evaluation, which is more conceptually aligned with service-design thinking, moves beyond these assumptions, emphasizing supportive adaptation to ensure meaningful adoption. Research limitations/implications Blended approaches that incorporate service-design thinking and rely more heavily on developmental strategies are essential for complex interventions. To maximize the benefit of this approach, three guiding principles are suggested: stress pragmatism over stringency; adopt an implementation lens; and use multi-disciplinary teams to run studies. Originality/value This viewpoint offers novel thinking on the debate around appropriate evaluation methodologies to be applied to complex interventions like models of integrated care.

Domain Specific Languages (DSL) are becoming increasingly more important with the emergence of Model-Driven paradigms. Most literature on DSLs is focused on describing particular languages, and there is still a lack of works that compare different approaches or carry out empirical studies regarding the construction or usage of DSLs. Several design choices must be made when building a DSL, but one important question is whether the DSL will be external or internal, since this affects the other aspects of the language. This chapter aims to provide developers confronting the internal-external dichotomy with guidance, through a comparison of the RubyTL and Gra2MoL model transformations languages, which have been built as an internal DSL and an external DSL, respectively. Both languages will first be introduced, and certain implementation issues will be discussed. The two languages will then be compared, and the advantages and disadvantages of each approach will be shown. Finally, some of the lessons learned will be presented.

The article deals with privatization in Russia’s energy sector with a special focus on a recent purchase of the private TNK-BP by the state-owned Rosneft. The author analyses the past, present and future privatization deals related to the Russian oil, gas and power generation industry as compared to accumulated international experience. For instance, the article displays the ways the Norwegian, Brazilian, French and British authorities privatized national strategic energy assets. The study presented in the article also aims to find out key advantages and disadvantages of state or private ownership in the Russian and global energy industry. For example, it sheds light on some considerable achievements of the Russian state-controlled companies in oil production amid a widespread belief that more than a decade-long growth in the Russian oil industry is due only to private firms that were created in the 1990s. Additionally, the state-controlled Norwegian oil and gas firm Statoil that shows strong operational and financial results on the Norwegian Continental Shelf and abroad is also in the spotlight of the current study. In line with the mentioned takeover of TNK-BP the author examines outcomes of the reorganization of RAO UES of Russia (the dismantled Russian electric power monopoly) that was seen as a massive privatization of the national power industry. Moreover, the study presents two groups of interests prevailing in the Russian government and energy business to give an outlook on the Russian energy industry.

Abstract The objective of this paper is to present the findings obtained from a detailed engineering evaluation resulting from trial testing two state-of-the-art surface horizontal pumping systems (HPS's) in two water supply wells. The two horizontal pumping systems were deployed as an alternative to downhole electrical submersible pumps (ESPs) to provide the benefits of eliminating ESP workover costs, modularity regarding wellsite deployments, and enhanced maintenance operations. For this trial test evaluation method, two HPS's were deployed to boost water production to the water injection plant (WIP). To ensure a thorough evaluation, the trial test well candidates were designed to accommodate both a subsurface ESP as well as a surface HPS to provide an accurate comparison, and representation, between the different artificial lift methods. The trial test and comparison method described in this paper focused primarily on the following items; maintenance and well intervention requirements, evaluation of operational availability, including potential for cavitation and effects of interference, maximum production rates, as well as root cause engineering evaluations for mechanical seals and cooling unit auxiliary motors. Various best practices and mitigation measures were identified and are presented in this paper. With regard to the results, it was observed that each artificial lift method comprised a set of advantages and disadvantages. The decision on which type of technology to use can be dependent on several factors. Overall, the HPS's demonstrated the ability to supply water production to the WIP. The HPS did experience operational challenges in providing higher production requirements. Additional challenges were also observed in the sealing mechanism as well as the auxiliary cooling unit. Precautionary pump tripping automated protocols were taken to prevent pump cavitation due to sub-optimal intake pressure resulting from possible interference. The HPS, unlike the ESPs, did not require any workover as it is located at the wellsite and therefore resulted in substantial cost savings and was easy to maintain due to its surface application. In summary, this paper adds a new and very beneficial evaluation of HPS's, and highlights best practices and lessons learned to the existing body of literature. The new information discussed in this paper is highly beneficial to engineering selections of artificial lift methods and to the successful implementation of HPS's in the industry.
