Meaningful, but effective? A critical evaluation of Ireland’s citizens’ dialogues on the future of Europe

On the 25 March 2017, leaders of the EU27 and European Union (EU) institutions ratified the Rome Declaration. They committed to invite citizens to discuss Europe’s future and to provide recommendations that would facilitate their decision-makers in shaping their national positions on Europe. In response, citizens’ dialogues on the future of Europe were instituted across the Union to facilitate public participation in shaping Europe. This paper explores Ireland’s set of dialogues which took place during 2018. Although event organisers in Ireland applied a relatively atypical and more systematic and participatory approach to their dialogues, evidence suggests that Irelands’ dialogues were reminiscent of a public relations exercise which showcased the country’s commitment to incorporating citizens into the debate on Europe while avoiding a deliberative design which could have strengthened the quality of public discourse and the quality of public recommendations. Due to an absence of elite political will for a deliberative process, as well as structural weaknesses in design, participants’ recommendations lacked any clear and prescriptive direction which could shape Ireland’s national position on the future of Europe in any constructive or meaningful way.
Cost-efficient factors in local public spending: Detecting relationships between local environments, population size and urban area category

This study examines regional differences in local environment factors to better understand the sustainability of local governments indexed by per capita public spending. Under the condition of heterogeneous population size, we examine how factor characteristics differ depending on the spatial context represented by the urban area category. By employing a Cobb–Douglas cost function with congestion effects on public service provision, the estimated factors enable us to articulate major factors and differences in cost-efficiency between urban area categories. We found that statistical significance and even the signatures of local environment factors differ depending on the urban employment area category. Regarding factors such as the ratios of employees in secondary and tertiary industries, these did not tend to be statistically significant in small-sized urban areas, while small-sized cities in large-sized urban areas were likely to gain confidence intervals. Moreover, we did not observe any statistical significance for the ratio of elderly people due to the balance of spending between national and local governments. These findings could contribute to sustainable management of cities in the advent of population decline.
Geochemical Characteristics and Migration Pathways of Ordovician Carbonate Oil Reservoirs in the Tuoputai Area, Tarim Basin, Northwestern China

Exploration potential is huge and the oil resources are rich in the Ordovician reservoirs of the Tarim Basin. However, the mechanism of hydrocarbon accumulation is complex and not yet fully understood. In the Tuoputai area, the hydrocarbon migration pathways and characteristics of deep hydrocarbon accumulation are revealed through analyses of the physical data of rich oil and gas, the geochemical parameters of oil, and fluid inclusions. The results show that the Ordovician oils in the Tuoputai area have the same geochemical characteristics as the mixed oil from the Lower Cambrian source rock and the Middle–Upper Ordovician source rock. The Ordovician reservoirs have been charged three times: in the late Caledonian, late Hercynian, and Himalayan stages. Oil charging occurred in the Hercynian stage, in particular, as it is the main filling period of hydrocarbon. The north‐northeast (NNE)‐trending TP12CX major fault, active in in these times and is dominant migration channel of hydrocarbon, but there is segmentation affected by the difference of activities. Oil maturity is higher in the south than in the north and is abnormally high near the major fault. Parameters related to migration indicate that oil migrated northeastward along the NNE‐trending TP12CX major fault and adjusted laterally along the secondary faults and weathering crust, forming the present characteristics of oil and gas distribution.
Ventilation History of the Nordic Seas Deduced From Pelagic‐Benthic Radiocarbon Age Offsets

Changes in ocean circulation are considered a major driver of centennial‐to‐millennial scale climate variability during the last deglaciation. Using four sediment records from the Nordic Seas, we studied radiocarbon ventilation ages in subsurface and bottom waters to reconstruct past variations in watermass overturning. Planktic foraminiferal ages show significant spatial variability over most of the studied period. These differences suggest that the ventilation of the shallower subsurface waters is strongly influenced by local conditions such as sea‐ice and meltwater input, changes in mixed‐layer depth, and/or variable contributions of water masses with different 14C signatures. Despite covering a significant water depth range, the benthic foraminiferal records show common long‐term patterns, with generally weaker ventilation during stadials and stronger during interstadials. The Greenland Sea record differs the most from the other records, which can be explained by the greater depth and the geographical distance of this site. The benthic records reflect regional shifts in deep convection and suggest that the deep Nordic Seas have been generally bathed by a single, though changing, deep‐water mass analogous to the present‐day Greenland Sea Deep Water. Since significant offsets in ventilation ages are yielded by different taxonomic or ecological groups of benthic foraminifera, the use of uniform material seems a prerequisite to reconstruct bottom water ventilation histories.
The potential of eye tracking for visual literacy research

Abstract The multitude of disciplines, perspectives, and practices that inform the study of visual literacy is incredibly valuable, but at the same time it means our research lacks a shared set of methodologies and methods. Unfamiliar research approaches may lead to mistrust of research findings and, even more problematic, to missed opportunities for knowledge development, opportunities that are vital to progress in the field. Eye tracking is one such method that is likely to be outside the traditional disciplinary approaches of most visual literacy scholars, yet it has the potential to be productive for many of the types of questions that the field seeks to answer. Following an introduction to eye-tracking methods, terminology, and data types, the article provides an overview of past eye-tracking research that can inform visual literacy studies. The article then turns to a discussion of visual literacy research that could potentially be addressed by eye-tracking methods.
COVID-19 induced lower-tropospheric ozone changes

The recent COVID-19 pandemic with its countermeasures, e.g. lock-downs, resulted in decreases in emissions of various trace gases. Here we investigate the changes of ozone over Europe associated with these emission reductions using a coupled global/regional chemistry climate model. We conducted and analysed a business as usual and a sensitivity (COVID19) simulation. A source apportionment (tagging) technique allows us to make a sector-wise attribution of these changes, e.g. to natural and anthropogenic sectors such as land transport. Our simulation results show a decrease of ozone of 8% over Europe in May 2020 due to the emission reductions. The simulated reductions are in line with observed changes in ground-level ozone. The source apportionment results show that this decrease is mainly due to the decreased ozone precursors from anthropogenic origin. Further, our results show that the ozone reduction is much smaller than the reduction of the total NO x emissions (around 20%), mainly caused by an increased ozone production efficiency. This means that more ozone is produced for each emitted NO x molecule. Hence, more ozone is formed from natural emissions and the ozone productivities of the remaining anthropogenic emissions increase. Our results show that politically induced emissions reductions cannot be transferred directly to ozone reductions, which needs to be considered when designing mitigation strategies.
Bandwidth Improvement of an Inverted-F Antenna Using Dynamic Hybrid Binary Particle Swarm Optimization

This paper proposes a Dynamic Hybrid Binary Particle Swarm Optimization (DH-BPSO) algorithm to improve the bandwidth of an inverted-F antenna (IFA). The proposed algorithm improves upon the existing Artificial Immune System (AIS) algorithm by including a weighting factor that dynamically changes throughout the optimization. DH-BPSO activates or deactivates a 12 × 2 grid of parasitic patches incorporated between the IFA and ground plane. The DH-BPSO optimized and conventional IFAs are fabricated and compared while maintaining the same antenna volume. The measurement results show that the optimized IFAs have characteristics of 58.6% wider bandwidths and 5.8% higher antenna gain for various ground clearance lengths at Long Term Evolution (LTE) 700 MHz band compared to the conventional IFAs.
Does Ketorolac reduce the intensity of postoperative pain after impacted third molars surgery in adults compared to the use of tramadol? A systematic review and meta-analysis

This systematic review and meta-analysis evaluated if ketorolac reduces the intensity of postoperative pain after impacted third molars surgery in adults compared to the use of tramadol. A comprehensive search was performed in the MEDLINE/PubMed, Scopus, Web of Science, LILACS, BBO, EMBASE, Cochrane Library, SIGLE and grey literature, in accordance with the PRISMA guidelines. The quality of the evidence was evaluated using the GRADE approach. Meta-analysis was performed on studies considered at low risk of bias. After duplicates removal, 4526 articles were identified, but only nine studies were included for qualitative analysis. After updating in 2021, four studies were added, totaling 13 studies included for qualitative analysis. Only two studies, classified at “low” risk of bias, were included in the meta-analysis of the primary outcome. The difference in means for pain intensity (moderate quality of evidence due to imprecision) was – 0.27 (95% CI = – 0.82 to 0.28; p = 0.34). Data from adverse effects (low quality of evidence due to very serious issues in imprecision) was just reported in one study at “low” risk of bias. Data was not heterogeneous (Chi2 test p = 0.14; I2 = 55%). It was not possible to evaluate any secondary outcomes (time to first rescue analgesic drug in h, total amount of analgesics consumed and adverse effects) due to low number of studies included. There is a lack of strong evidence to assure the superiority of ketorolac or tramadol in reducing the postoperative pain after extraction of impacted third molars.

Open Covid‐19: Organizing an extreme crowdsourcing campaign to tackle grand challenges

This article presents an extreme crowdsourcing case to tackle grand challenges such as Covid‐19. Researchers became more interested in crowds’ involvement to deal with grand challenges and scholars reported the use of crowdsourcing in producing innovative solutions to solve these challenges. Driven by recent calls for more research to examine forms of socially motivated interaction options in order to support crowds in dealing with these ill‐defined problems, this research conducts a qualitative study of how an extreme crowdsourcing program – Open Covid‐19 launched by Just One Giant Lab to develop and test low‐cost solutions to tackle the pandemic – was organized. By examining conditions for coordination and knowledge exchange in the Open Covid‐19 case, we present an open structure where the challenges of predictability and common understanding have to be managed continuously and the participants themselves gradually build accountability; multidisciplinary knowledge integration is achieved by exchanging efforts and skills, and extreme transparency contributes positively in building a collective project memory. These findings are theoretically important because they clarify how extreme crowdsourcing can be organized to deal with grand challenges.
An isomorphism of the Wallman and Čech-Stone compactifications

Abstract For a metrizable topological space X it is well known that in general the Čech-Stone compactification β(X) or the Wallman compactification W(X) are not metrizable. To remedy this fact one can alternatively associate a point-set distance to the metric, a so called approach distance. It is known that in this setting both a Čech-Stone compactification β*(X) and a Wallman compactification W*(X) can be constructed in such a way that their approach distances induce the original approach distance of the metric on X [23], [24]. The main goal in this paper is to formulate necessary and suﬃcient conditions for an approach space X such that the Čech-Stone compactification β*(X) and the Wallman compactification W*(X) are isomorphic, thus answering a question first raised in [24]. The first clue to reach this goal is to settle a question left open in [11], to formulate suﬃcient conditions for a compact approach space to be normal. In particular the result shows that the Čech-Stone compactification β*(X) of a uniform T 2 space, is always normal. We prove that the Wallman compactification W*(X) is normal if and only if X is normal, and we produce an example showing that, unlike for topological spaces, in the approach setting normality of X is not suﬃcient for β*(X) and W*(X) to be isomorphic. We introduce a strengthening of the regularity condition on X, which we call ideal-regularity, and in our main theorem we conclude that X is ideal-regular, normal and T 1 if and only if X is a uniform T 1 approach space with β*(X) and W*(X) isomorphic. Classical topological results are recovered and implications for (quasi-)metric spaces are investigated.
Prevalence and risk factors of overweight among adolescents: an analysis of Bhutan Global School-based Student Health Survey data

ABSTRACT The burden of overweight and obesity in children and adolescents has increased, especially in developing countries, posing a significant health challenge. Data on factors influencing overweight among adolescents is scarce in Bhutan. The present study examined the factors associated with overweight among school-going adolescents in Bhutan. This study analysed the nationally representative data from the Bhutan Global School-based Student Health Survey (BGSHS) conducted in 2016. The factors associated with overweight were identified by conducting multiple logistic regression analysis using a backward elimination approach. The complex survey design of the BGSHS was accounted for in the analysis. This study found that the prevalence of overweight was 11.35%. The findings showed that females, adolescents who were day students, and sedentary had higher odds of being overweight, whereas those aged >15 years and received education on healthy eating had reduced odds in the full sample. Female adolescents who were sedentary had increased odds of overweight. In the males’ only sample, being a day student and living in urban areas was associated with increased odds of overweight, whereas those boys who received education on healthy eating and smoked cigarettes had reduced odds. Being >15 years of age was a common factor associated with reduced odds of overweight. Based on findings, policies aimed to reduce sedentariness and promote a healthy diet and behaviour can help reduce the risk of being overweight. Interventions targeting females, young adolescents, day students, and adolescents living in urban areas may be cost-effective.
Potential Use of the Benthic Foraminifers Bulimina denudata and Eggerelloides advenus in Marine Sediment Toxicity Testing

The benthic foraminifers Bulimina denudata and Eggerelloides advenus are commonly abundant in offshore regions in the Pacific Ocean, especially in waste-discharge sites. The relationship between their abundance and standard macrofaunal sediment toxicity tests (amphipod survival and sea urchin fertilization) as well as sediment chemistry analyte measurements were determined for sediments collected in 1997 in Santa Monica Bay, California, USA, an area impacted by historical sewage input from the Hyperion Outfall primarily since the late 1950s. Very few surface samples proved to be contaminated based on either toxicity or chemistry tests and the abundance of B. denudata did not correlate with any of these. The abundance of E. advenus also did not correlate with toxicity, but positively correlated with total solids and negatively correlated with arsenic, beryllium, chromium, lead, mercury, nickel, zinc, iron, and TOC. In contrast, several downcore samples proved to be contaminated as indicated by both toxicity and chemistry data. The abundance of B.denudata positively correlated with amphipod survival and negatively correlated with arsenic, cadmium, unionized ammonia, and TOC; E. advenus negatively correlated with sea urchin fertilization success as well as beryllium, cadmium, and total PCBs. As B. denudata and E. advenus are tolerant of polluted sediments and their relative abundances appear to track those of macrofaunal toxicity tests, their use as cost- and time-effective marine sediment toxicity tests may have validity and should be further investigated.
Green Product Design and Pricing Decisions in a Risk-Averse Supply Chain under Alternative Power Structures

Motivated by the prevailing green product design and the different supply chain power structures, this paper aims to analyse the role of power relationship and risk-aversion in economic and environmental performance of sustainable supply chain. Three game theory models, including the manufacturer Stackelberg (MS) model, retailer Stackelberg (RS) model, and vertical Nash (VN) model, are developed to study the pricing and greenness level decisions in a two-echelon sustainable supply chain, where one risk-averse manufacturer sells green products through one risk-averse retailer. This paper shows that when selling through a more risk-averse retailer, the risk-averse manufacturer prefers to provide a product with a higher level of greenness and achieve a greater utility regardless of the power structure. A manufacturer as a follower may have stronger motivation to increase the product’s level of greenness than one in a more balanced supply chain when the green technology investment coefficient is sufficiently low. With regard to the power structure, the channel leadership is not necessary to for the manufacturer to achieve higher utility, which depends on the green technology investment coefficient, greenness level sensitivity, and players’ risk aversion.
Seasonal Variability and Propagation Environment to Graft Success and Growth of Sapling in Tropical and Subtropical Fruit Crops: A Review

Grafting is a widely used propagation technique in fruit trees. Anatomical proximity between scion and rootstock is the prerequisite for the successful graft-take and survival of the grafted plants. The success of grafting, subsequent growth of scion shoot and development of the successful grafts depend upon several factors like climatic conditions, the growth stage of scion and rootstock, methods of grafting, etc. The grafting response of fruit crops differs due to seasonal variability and environmental condition where grafting is carried out. A controlled environment with the congenial conditions for faster healing and callus formation results in better graft success, survival and growth of grafted plants.
Issues and perspectives of capacity development in embodied energy indices for building materials sourced in Nigeria: A review

Embodied energy (EE) property of building material is a great determinant of the performance of a building. The dearth of information on EE of locally sourced building materials (LSBMs) constitutes a challenge to affordable housing in Nigeria. In this paper, a review of the previous literature, unfilled gaps in those works, and future directions in embodied energy research for LSBMs is presented to evolve a Nigerian perspective. A constructive non-meta analytic methodology was adopted for the paper. This was followed by classification and comparison of snapshot literature in the embodied energy of building materials. Insightful sources of information for the study were drawn from a vast body of knowledge both documented literature and some interviews with knowledgeable personnel in the area of a built environment. From the survey, energy management opportunities were revealed, which would not have been apparent from a specific building case study alone. There are distinctions in the literature with this current paper for a Nigerian case study: none have addressed the embodied energy coefficient of materials. Also, the status of embodied energy studies, for these materials, is at a low profile and the few investigations carried out focused on life cycle operating energy of buildings. These research gaps evidently imply abundant research opportunities that await exploitation in the building industry. This paper adds to an existing body of knowledge on the use of EE index to promote and optimize the selection of LSBMs as alternative to imported building materials. We hope engineers, estate developers and architects would find it useful for making an informed decision in the design of resilient buildings using indigenous materials. http://dx.doi. org/10.4314/njt.v39i4. 21
Revolution From Above? Female Directors’ Equality-Related Actions in Organizations

Drawing on interviews with women and men who serve on the supervisory boards of German stock-listed companies, this qualitative study examines why some female directors seek to augment gender equality in their organizations while others do not. Those who take action do so both in formal board processes and in informal settings. A sense of belonging to women as a social group and a sense of responsibility for women in the organization are key factors in explaining why some female directors contribute to gender equality. In addition, the study highlights the relevance of a board culture supportive of gender equality and positive expectations by other organizational members about female directors’ role in advancing gender equality. Board chairs influence how supportive female directors perceive the organizational context to be. Where the organizational context is not seen as supportive, those who take equality-related action anyway are experienced directors. Surprisingly, the presence of other women on the board does not appear to be related to whether or not female directors take action. Examining female directors’ actions and paying close attention to both their identities and their specific organizational settings shows how the interplay between social identity and situational opportunities and constraints affects board behavior.
