AbstractResponding effectively to climate crisis requires strong science-policy links to be put in place. Past research on the research-policy interface indicates longstanding challenges that have become more acute in the case of climate science, since this requires multi-disciplinary approaches and faces distinctive political challenges in linking knowledge with policy. What can be learned from the experiences of university-based researchers seeking to influence policy as they try to operate in the brokering space? With this in mind, an empirical study was designed to capture the detailed views and experiences of forty researchers in four universities across four countries—Bangladesh, Germany, Uganda and UK. It found a wide range of different researcher attitudes to policy engagement, diverse methods of engaging, a preference for working with government and civil society over private sector policy actors, and a perceived need for more university support. The findings suggest a need to rethink conditions for engagement to create spaces for knowledge exchange and cooperation that can contribute to policies for societal transformation. More attention also needs to be paid to interdisciplinary research approaches, improving research connections with private sector actors, and strengthening university research links with local communities. Finally, the position of university based researchers in the Global South will require strengthening to improve North–South knowledge exchange, capacity development, and incentives for policy engagement.

Authors: Viana-Lora Alba , Nel-lo-Andreu Marta Gemma 
Published: May 2022

AbstractThe aim of the research is the bibliometric analysis of research on COVID-19 and tourism in order to detect research lines and gaps, the main authors, the countries with the highest number of publications, the most analysed study areas, the journals with the most number of publications and the articles with the highest number of citations. The Web of Science (WOS) database was used to extract the publications and the VOSviewer software was used to represent the data analysed. The keywords used resulted in 1792 publications that were subjected to a filtering process to avoid introducing articles that did not meet the inclusion criteria. Finally, the analysis was composed by 921 publications. The analysis locates a new line of research that visualizes the crisis as an opportunity to propel a new, more sustainable tourism. Tourist perception and the risk of transmission, together with the analysis of measures and policies are other of the most researched topics. China is the country with the most articles on COVID-19 and tourism according to the author’s main affiliation, as well as being the most analysed area of study. To the best of our knowledge, this is the first article to carry out a bibliometric analysis of COVID-19 and tourism publications.

AbstractCommunity and religious leaders and other natural leaders from culturally and linguistically diverse (CaLD) backgrounds have been postulated as a gateway into communities. They act as information intermediaries that enable public health messages to reach individuals. However, there are currently limitations regarding our understanding of these information intermediaries’ regarding their capacity, role, and reach. In-depth interviews were undertaken to understand the perceptions of those working in Australia, including multicultural health, communication and other social support roles focused on CaLD communities, towards the role and impact of information intermediaries in promoting and supporting COVID-19 public health communication and engagement activities. Forty-six semi-structured telephone interviews were undertaken with key stakeholders who have an active role in delivering services and other social support to CaLD communities. Four key themes emerged related to the role of information intermediaries during the interviews. Ideas focused on their role in “bridging the gap” and supporting pandemic-related information delivery into communities. Participants felt that there had been a failure by Federal government agencies to recognise the role of these stakeholders early in the pandemic and a failure to provide sufficient resources and support. However, concerns were also raised that public health messages may be inappropriately interpreted or translated by the community information intermediaries or potentially blocked if the message does not align with the broker’s own beliefs. Finally, concerns were raised about the potential for burn-out among information intermediaries. In preparing and responding to pandemics and other disasters, community leaders and other information intermediaries recognise they have an important role to play and must be provided with resources to enhance and sustain their involvement.
Explore, engage, empower: methodological insights into a transformative mixed methods study tackling the COVID-19 lockdown

AbstractAction-oriented, transformative, and transdisciplinary approaches are increasingly heralded as promising tools that enable researchers not only to produce new knowledge about a situation, but also to actively engage in tackling it; however, such approaches raise critical questions about the methodological implications and conflicts involved in pursuing multiple objectives concurrently. This article seeks to advance this debate by examining the methodological implications of pursuing both knowledge production-oriented (epistemic) and action-oriented (transformative) objectives in urgent and uncertain situations. It asks how far a transformative mixed methods research design can leverage the potential of research to achieve multiple objectives in times of crisis. This methodological inquiry is based on a transformative mixed methods study on housing conditions and well-being which was initiated during the first COVID-19 lockdown in Switzerland. The study was composed of a country-wide survey, mobile crowdsourcing, interviews and Citizen Think Tanks. The results of this methodological reflection illustrate how this research design made it possible to (i) explore the effects of the crisis on domestic living spaces, (ii) engage with the crisis in a joint research space, and (iii) stimulate empowerment through reflection and mutual learning. These insights suggest the multidimensional orientation of the transformative mixed methods approach is appropriate for acting upon urgent crises. However, it challenges core methodological values and research constellations including (i) tackling unequal engagement opportunities, (ii) navigating social and epistemic control, and (iii) paying attention to situatedness and positionality. The article concludes that, in anticipation of future crises, favorable conditions for multi-targeted, collaborative research need to be fostered, both on the institutional and on personal levels. These conditions should enable fast and adequate team formation, as well as reflection and negotiation of positionalities, and divergent interests and objectives, of both scientists and citizens.
Between détente and the shock of the global. The late Franco regime and its meaning for transatlantic relations (1975)
Authors: Robles Asensio 
Published: May 2022

AbstractThis article examines how the Franco regime influenced transatlantic relations in 1975. The imminent death of General Francisco Franco, seen as part of the transnational Southern Flank crisis, represented an intellectual challenge for the West. As such, it forced US and Western European policymakers to test their divergent understandings of détente. Yet this new divide did not strain transatlantic relations. Happening in parallel to the world recession and the international energy crisis, it instead served to highlight transatlantic interdependency during a time of major global transformations. Thus, the Spanish dictatorship contributed to moving Western countries towards new forms of multilateralism.
Broadband resonance-enhanced frequency generation by four-wave mixing in a silicon Floquet topological photonic insulator
Authors: Zimmerling T. J. , Afzal S. , Van V. 
Published: May 2022

Floquet topological photonic insulators, whose light transport properties are dictated by the periodic drive sequence of the lattice, provide more flexibility for controlling and trapping light than undriven topological insulators. This can enable novel nonlinear optics applications in topological photonics. Here, we employ a novel resonance effect called Floquet Defect Mode Resonance (FDMR) in a 2D silicon Floquet microring lattice to demonstrate resonance-enhanced frequency generation by four-wave mixing of Floquet bulk modes in the presence of Kerr nonlinearity. The compact, cavity-less resonance mode, induced through a periodic perturbation of the lattice drive sequence, has the largest reported Q-factor for a 2D topological resonator of ∼105 with low group velocity dispersion, which enables efficient broadband frequency generation over several Floquet–Brillouin zones of the Floquet topological insulator. We achieved wavelength conversion over a 10.1 nm spectral range with an average enhancement of 12.5 dB in the conversion efficiency due to the FDMR. Our work could lead to robust light sources generated directly on a topologically protected photonic platform.

Context Weaned lambs raised on pasture-based systems in Brazil are often subjected to periods of forage shortage, limiting their nutrient and energy intake and, hence, their growth. Fast recovery of lamb body weight is important to the efficiency, sustainability and profitability of these sheep production systems. Aim We evaluated the effects of refeeding on growth performance, blood metabolites and physiological parameters of Dorper × Santa Ines lambs after low and moderate feed restriction, to determine whether there was a compensatory growth response. Methods Twenty-four non-castrated male lambs were assigned to a completely randomised design with three treatments and eight replicates. The trial was conducted in a feedlot and divided into two phases: (1) feed restriction for 64 days, and (2) refeeding for 42 days. In Phase 1, the respective treatments provided energy supplies of 0.481, 0.841 and 1.205 MJ metabolisable energy per kg metabolic weight daily, corresponding to 60% (PR60, moderate) and 30% (PR30, low) feed restriction levels and ad libitum intake. In Phase 2, the lambs in PR60 and PR30 treatments were refed ad libitum. Performance and blood measurements were taken in Phase 1 for the ad libitum treatment, and Phase 2 for PR60 and PR30 treatments. Key results Highest initial and final bodyweights of 32.7 and 41.2 kg were recorded in the PR30 treatment during Phase 2, compared with 23.0 and 36.7 kg averaged over PR60 and ad libitum treatments. Average daily gain did not differ among treatments (276 g/day, on average). Dry matter intake was significantly higher in PR30 than the ad libitum treatment (1406 vs 1158 g/day), with PR60 intermediate (1267 g/day). Serum levels of albumin, urea and creatinine indicated that protein metabolism was strongly affected by the PR60 treatment. High metabolic rate and subsequent rapid growth determined high respiratory rate and rectal temperature in the lambs from PR60 and PR30 treatments. Conclusions Moderate feed restriction relative to maintenance level followed by an ad libitum refeeding period in the feedlot leads to a strong compensatory growth response in Dorper × Santa Ines lambs. Implications In periods of low feed availability, keeping weaned lambs under moderate feed restriction is a good strategy to induce an efficient compensatory growth response in the feedlot during the finishing phase.
How local partisan context conditions prosocial behaviors: Mask wearing during COVID-19
Authors: Baxter-King Ryan , Brown Jacob R. , Enos Ryan D. , Naeim Arash , Vavreck Lynn 
Published: May 2022

Significance
Differences between Democrats and Republicans in rates of wearing a mask to stop the spread of COVID-19 are associated with the partisan balance of a neighborhood. The difference in rates grew larger as the share of Republicans in a neighborhood increased. This finding appears to be driven by decreased rates of mask wearing by Republicans who live among increasing numbers of Republicans (and not by Democrats in the same neighborhood). Theories about social pressure suggest these findings may be driven by the politicized and publicly observable nature of wearing a mask relative to other COVID-19 mitigation strategies, like vaccination. Neighborhood partisan composition was only weakly related to uptake of the COVID-19 vaccine and unrelated to uptake of flu vaccines.
Rhetorical questions as reproaching devices
Authors: Albelda Marco Marta 
Published: May 2022

Abstract
This paper studies rhetorical questions containing cognitive verbs that function as reproaches in Spanish. Its two
main goals are to determine the degree of specialization of rhetorical questions as reproaches and to examine the characterization
of reproaching as a speech act, indicating the distinctive features that distinguish it from other similar speech acts.
Based on a contextual analysis of approximately 500 instances of reproaches in conflict talk drawn from the
Spanish Royal Academy’s Corpes XXI corpus, I identify and describe the most commonly used cognitive verbs and syntactic structures used
in rhetorical questions. The results show that reproach is a reactive-provocative speech act in which the speaker reacts to a
contradiction perceived in their interlocutor’s words, actions or thoughts. The speaker appeals to their interlocutor’s moral
conscience, making them think about this inconsistency; finally, the speaker creates the expectation of a duty that should have
been carried out by the interlocutor.
Investigating the prevalence of low energy availability, disordered eating and eating disorders in competitive and recreational female endurance runners

Published: May 2022

ABSTRACTEating disorders (ED), disordered eating (DE) and low energy availability (LEA) can be detrimental to health and performance. Previous studies have independently investigated the prevalence of ED, DE or LEA; however, limited studies have combined methods identifying risk within female runners. The aim of this study was to identify the prevalence of ED, DE and LEA in United Kingdom‐based female runners and associations between age, competition level and running distance. The Female Athlete Screening Tool (FAST) and Low Energy Availability in Females Questionnaire (LEAF‐Q) were used in a cross‐sectional study design. A total of n = 524 responses eligible for analysis were received. A total of n = 248 (47.3%), n = 209 (40%) and n = 49 (9.4%) athletes were at risk of LEA, DE and ED, respectively. LEAF‐Q scores differed based upon age (Age: H(3) = 23.998, p ≤ .05) and competitive level (Comp: H(1 ) = 7.682, p ≤ .05) whereas FAST scores differed based on age (Age: F(3,523) = 4.753, p ≤ .05). Tukey's post‐hoc tests showed significantly higher FAST scores in 18–24 years compared to all other age categories (p ≤ .05). Stepwise multiple regression demonstrated age and competitive level modestly predicted LEAF‐Q scores (R 2 adj = 0.047, F(2,523) = 13.993, p ≤ .05, VIF = 1.0) whereas age modestly predicted FAST scores (R 2 adj = 0.022, F(1,523) = 12.711, p ≤ .05, VIF = 1.0). These findings suggest early identification, suitable screening methods and educational intervention programmes should be aimed at all levels of female endurance runners.Highlights
A total of 524 female endurance completed a self‐administered, online questionnaire screening for low energy availability, disordered eating and eating disorders risk.
Age and competitive level modestly predicted low energy availability and age modestly predicted disordered eating and eating disorders in female endurance runners.
A higher percentage of 18‐ to 24‐year‐old female endurance runners were at greater risk of low energy availability, disordered eating and eating disorders compared to other age categories.
These findings highlight the need for regular screening in order to aid early interventions to prevent potential decrements in performance and health as endurance runners mature.
Characterization and compensation of thermal bias drift of a stiffness-tunable MEMS accelerometer

Published: May 2022

Abstract
This paper presents characterization and compensation of the thermal bias drift of a MEMS accelerometer whose effective stiffness is electrostatically tuned to a low value with the help of the single-sided parallel plates (SSPPs) capacitors. A temperature drift model for the proposed accelerometer is built and the temperature effect on the mechanical stiffness and the circuit gains is characterized. The characterization reveals that the variations of the feedforward coefficient including the mechanical stiffness and the readout gain due to the temperature change play a significant role in the bias drift of output of the proposed closed-loop accelerometer. On the other hand, the variations of both feedback gain and tuning gain as a function of temperature are one-order-of-magnitude less than that of the feedforward coefficient. To calibrate the feedforward coefficient, an excitation signal as a form of AC reference displacement is introduced to drive the proof mass and the readout response is demodulated to calibrate the variance of the feedforward coefficient correspondingly. An open-loop compensation scheme for the temperature-induced bias drift using the variance of the calibrated response is proposed accordingly. Alternatively, the calibrated response can be controlled to a preset value by a new proportion integral derivative (PID) controller by the adjustment of the SSPP tuning voltage. The output of the PID controller is used for the calibration of the introduced bias from the electrostatic tuning force. Therefore, a closed-loop compensation of the thermal bias drift is achieved by remaining the feedforward coefficient while eliminating the calibrated bias. Experiments under a temperature cooling process and different tuning voltages are carried out to verify two proposed compensation schemes. The temperature drift coefficients (TDCs) of both compensated outputs exhibit at least one-order-of-magnitude reduction in response to the temperature change. When the effective stiffness of the accelerometer is tuned to about 4.19 N m−1, the TDC of the compensated output using the proposed open-loop or closed-loop compensation schemes is reduced to about 0.1136 or 0.0391 mg °C−1, respectively and meanwhile, the Allan bias instability is slightly increased to 48.63 or 56.14 μg, respectively.

Published: May 2022

Abstract
Two of the most important features in the field of nanotechnology are self-assembly with nanometre-scale precision, and the self-alignment of functionalised nanomaterials. Here, we discuss the binding feasibility of single-strand spacer-added DNA building blocks to biotin–streptavidin (SA) complexes. We use atomic force microscopy, photoluminescence (PL) spectroscopy, and dynamic simulation to study the topological, optical, and vibrational characteristics of DNA lattices. To construct the DNA lattices, we use two distinct DNA building blocks, i.e. a double-crossover tile with a biotin (DXB), and a double-crossover tile with a flexible single-strand spacer containing a biotin (DXSB). Biotinylated DXB and DXSB lattices grown on the substrate eventually attracted streptavidins (SA, a tetramer protein) and formed DXB + SA, and DXSB + SA lattices, respectively. Furthermore, we examine the feasibility of alignments of an individual DXB (DXSB) tile on SA-bound DXB (DXSB) lattices, and a SA-conjugated Au nanoparticle (NP) on DXB (DXSB) lattices. To use more than two binding sites of biotins on SA (to serve as a connector between biotinylated tiles), the introduction of flexible single-strand spacers in DX tiles helped to overcome geometrical hindrance. In addition, the PL spectra of DXB and DXSB lattices with SA–Au conjugates are analysed to understand the periodic bindings of Au NPs on DXB (DXSB) lattices. We also conduct dynamic simulations of modal analysis and molecular dynamics simulation, which provide the vibrational characteristics and evidence of the importance of single-strand spacer-added DNA samples. Patterning of nanomaterials with specific functionalities with high precision using a simple method would be useful for the manufacture of high-density nanoelectronic devices and extreme-sensitivity biosensors.
