A qualitative and quantitative study of thrips (Thysanoptera) on alfalfa and records of thrips species on cultivated and wild Medicago species of Greece

Abstract Foliage and litter samples of twelve Medicago species (medics) (Fabaceae) were collected for the study of Thysanoptera from mainland and insular Greece between 2007-2013. The species composition, population dynamics and spatial distribution of thrips were also evaluated based on two similarly managed experimental plots, except the number of cuttings, within an alfalfa hay field in Kopais Valley (Central Greece) between 2007-2008. Nine thrips species were recorded from nine medics, two of which (Pseudodendrothrips mori and Sericothrips bicornis) are new to the Greek fauna. Eight species of Thysanoptera were recorded on alfalfa and five species in the rest of the medics, among which Medicago strasseri is an endemic shrub of Crete. Data regarding the quantitative part of the study demonstrated that Frankliniella occidentalis, which was the most abundant thrips species in both plots, presented a seasonal pattern of population fluctuation and also tended to aggregate. The mean population density of this species significantly differed between the above-mentioned plots, but no such a difference was estimated for the larvae of Thripidae.
Simplified approach for the optimal number of rotors and support structure design of a multi rotor wind turbine system

In this study different multi rotor wind turbine systems (MRSs) are designed in such a way that the space frame, forming the connection between rotor nacelle assemblies (RNAs) and tower, will be modeled and dimensioned as an ideal truss work. The main focus is on multi digit MRSs (MD-MRS) with a high number of rotors. To dimension the tube diameters and wall thicknesses, a simplified load case is used with an adjusted safety factor for loads. Parameters that are varied are the number of rotors, depth of the space frame, as well as the location of the fixed bearing for the yaw system. As such, the simplified approach is a preliminary step helping to choose a good design parameter combination for a more detailed and comprehensive analysis. Buckling is a main design driver, as well as the thrust forces. For a high number of rotors, a fixed bearing position and therefore tower height, halfway through the space frame height seems favorable regarding the cost.
When does an ethical attribute matter for product evaluation? The role of warm‐glow feelings for low‐rated products

Funding information Swiss Commission for Technology and Innovation (CTI), Grant/Award Number: KTI 1155000154 Abstract Research on the effects of ethical attributes has recently gained traction. However, limited research has addressed consumer response to ethical attributes in the current context where product ratings have become of primary importance to make decisions. Specifically, this study examines the relative effect of ethical attributes on product evaluations across different product ratings. Building on cue consistency theory and the negativity bias, we suggest that ethical attributes gain weight when consumers evaluate a low‐rated product. This process leads consumers to anticipate more warm‐glow feelings, generating better evaluations for such low‐rated products featuring an ethical attribute (vs. another type of attribute). Two experiments provide consistent empirical support for this prediction, and demonstrate that, compared to other attributes or no attribute, an ethical attribute increases product evaluations to a larger extent when the product received low (vs. higher) ratings. We show that this effect occurs because of warm‐glow feelings: when product ratings are low, consumers anticipate more warm‐glow feelings from purchasing a product with an ethical attribute (vs. another type of attribute), leading to better product evaluations. These findings have direct managerial and ethical implications for practitioners.
Restoration of tropical montane cloud forests: a six‐prong strategy

Tropical Montane Cloud Forests (TMCFs) are among the vegetation types facing the greatest threats, both globally and in Mexico. Ecological restoration of TMCFs is a priority in several tropical countries. In this paper, we propose that restoration of TMCFs based on applied nucleation methods should be accompanied by a set of additional mechanisms that form a six‐prong strategy. In our experience, the essential set of tools to ensure positive results is composed of (1) a diagnostic‐prescriptive stage; (2) species selection and nursery management of native species for restoring the tree strata; (3) the use of a set of biological indicators to monitor its progression; (4) restoration training for local and government stakeholders; (5) active dissemination of information through a network of private landowners; and (6) voluntary land protection. The proposed framework is based on a decade of interdisciplinary work of the Mexican conservation nonprofit organization Pronatura Veracruz. Although nucleation has been proposed and used to accelerate the natural succession of other tropical forests, there is no detailed documentation of concurring elements to achieve its long‐term success.
In a group of its own? Rediscovery of one of the world’s rarest and highest mountain bumblebees, Bombus tanguticus

The distinctive, large bumblebee Bombus tanguticus Morawitz was described from yellow-banded queens (females) collected from high elevations on the Qinghai-Tibetan Plateau (QTP) by Nikolay Przhevalsky’s fourth Central Asia expedition. One of Morawitz’s syntype females is designated here as lectotype. Because of the distinctive female morphology, Pittioni placed the species in a subgenus of its own, Tanguticobombus. Surprisingly, in the 130 years since its description, and despite extensive sampling of bumblebees across the QTP, records for just seven more individuals of B. tanguticus have been published, all queens. In this paper I report two recently collected workers (females) that extend the known distribution of the species and describe a new white-banded colour pattern from one of the workers. Available data on the species’ distribution are mapped, the location of the collecting site for the highest confirmed records of any bumblebees worldwide at c. 5640 m above sea level is discussed, and the closest relatives of the species identified, placing it in the lapidarius-group of the subgenus Melanobombus and most likely close to the European B. lapidarius.
The Roles of Different Design Techniques in Learning Tactical Scenes of Play through Dynamic Visualizations: A Brief Review

Dynamic visualizations have been developed to exchange information that 24 transforms over time across a broad range of professional and academic contexts. However, 25 these visual tools may impose substantial demands on the learner’s cognitive resources that 26 are very limited in current knowledge. Cognitive load theory has been used to improve 27 learning from dynamic visualizations by providing certain design techniques to manage 28 learner cognitive load without adding any oral/written explanations. This systematic review 29 examined a series of experimental studies assessing the roles of these design techniques in 30 learning tactical scenes of play through dynamic visualizations. Electronic databases PubMed 31 and Google Scholar were used to search relevant articles. Eleven studies were eventually 32 included for the systematic review based on the eligibility criteria. The present review 33 revealed that adapting design techniques to the level of learners’ expertise, type of depicted 34 knowledge, and level of content complexity is a crucial part of effective learning. 35
Determining the Residual Magnetic Flux Value of a Single-Phase Transformer Using a Minor Hysteresis Loop

Residual magnetic flux can cause significant problems in electric power system operation if not taken into consideration. The laboratory setup and experimental procedure for determining the residual magnetic flux value of a single-phase transformer using a minor hysteresis loop are presented in this paper. Using the proposed method, residual magnetic flux could be determined without prior knowledge about the last de-energization of the transformer. Only voltage and current measurements are needed, and any physical intervention in the core or in some other parts of the transformer is unnecessary. Also, a significantly lower voltage than the transformer's nominal is used to determine the residual magnetic flux value in the proposed method. The pros and cons of the proposed method, as well as plans for future research are given.
Cultivating creativity in a high-performing education system: The example of Singapore

Abstract Focusing on the cultivation of twenty-first century competencies in a high-performing education system, this article examines the teaching and learning of creativity in Singapore. It is argued that “everyday creativity” and creativity as innovation are privileged by educators in Singapore. Creativity is promoted through a harmonized approach that is manifested in two main ways. First, novelty and usefulness are integrated with the help of design thinking for the sake of social good. Secondly, the advancement of creativity co-exists with and supports the high-stakes examination system by infusing creative thinking into the teaching of school subjects. The example of Singapore adds to the existing research by demonstrating a cultural approach to the teaching and learning of creativity as well as the potential of design thinking to developing creative thinking in students.
Current status of targeted microbubbles in diagnostic molecular imaging of pancreatic cancer

Abstract Pancreatic ductal adenocarcinoma (PDAC) is often associated with a poor prognosis due to silent onset, resistance to therapies, and rapid spreading. Most patients are ineligible for curable surgery as they present with advanced disease at the time of diagnosis. Present diagnostic methods relying on anatomical changes have various limitations including difficulty to discriminate between benign and malignant conditions, invasiveness, the ambiguity of imaging results, or the inability to detect molecular biomarkers of PDAC initiation and progression. Therefore, new imaging technologies with high sensitivity and specificity are critically needed for accurately detecting PDAC and noninvasively characterizing molecular features driving its pathogenesis. Contrast enhanced targeted ultrasound (CETUS) is an upcoming molecular imaging modality that specifically addresses these issues. Unlike anatomical imaging modalities such as CT and MRI, molecular imaging using CETUS is promising for early and accurate detection of PDAC. The use of molecularly targeted microbubbles that bind to neovascular targets can enhance the ultrasound signal specifically from malignant PDAC tissues. This review discusses the current state of diagnostic imaging modalities for pancreatic cancer and places a special focus on ultrasound targeted‐microbubble technology together with its clinical translatability for PDAC detection.
Face masks as layers of meaning in times of COVID-19

The pandemic of COVID-19 has brought to the front a particular object: the face mask. I have explored the way people make-meaning of an object generally associated with the medical context that, under exceptional circumstances, can become a presence in everyday life. Understanding how people make meaning of their use is important. Using cultural psychology, I analyse preferences toward different types of face masks people would wear in public. The study involved 2 groups, 44 Norwegian university students and 60 international academics. In particular, I have focused on the role of the mask in regulating people affective experience. The mask evokes safety and fear, it mediates in the auto-dialogue between “I” and “Me” through the “Other”, and in the hetero-dialogue between “I” and the “Other” through “Me” The dialogue is characterized by a certain ambivalence, as expected. Meaning-making is indeed the way to deal with the ambivalence of human existence.
Wild seedlings of a tree endemic on granite outcrops show no evidence of inbreeding depression

Plant communities on granite outcrops are characterised by high biodiversity and endemism, and strong population genetic structuring. The floristic diversity and structure of inselberg flora receives much attention in international conservation research, yet our understanding of how recruitment influences population genetic structure of plants endemic to granite outcrops is limited. To determine the immediate genetic consequences of recruitment and to quantify mating and dispersal patterns by parentage analysis, I conducted an opportunistic study following a wildfire in a stand of the lignotuberous tree Eucalyptus caesia Benth. (Myrtaceae) at Boyagin Nature Reserve. The entire adult stand (n = 180) plus seedlings (n = 115) were genotyped with 14 microsatellite loci. Compared with adults, seedlings had low heterozygosity and a high inbreeding co-efficient, but similar levels of allelic diversity. There was no evidence of post-germination selection against homozygous seedlings over the 20 month survey period. Seedlings that resulted from cross-pollination were more heterozygous than seedlings resulting from selfing, but could not be distinguished based on height measurements or survivorship. Parentage analysis in CERVUS revealed mostly limited seed dispersal, assuming that candidate parents closest to seedlings were the maternal parent. By comparison, pollen movement was more extensive, yet still restricted to plants within the stand. Recruitment has increased the population size, but appears insufficient to enhance genetic diversity in the Boyagin stand of E. caesia. Nonetheless, E. caesia appears adept at persisting as extremely small populations.
Dynamics of Underwater Bar of Sandy Coast under the Influence of Wave Action According to the Monitoring Observations

Purpose. Morphodynamic system of the accumulative sandy coast can include one or more underwater bars. Position and shape of the underwater bar can reflect both seasonal changes of the coastal profile and its unidirectional movements landward and seaward. Determination of the character of the underwater bar movement under the influence of various wave conditions permits to reveal common factors of the coastal deposit multidirectional transport along the coast profile. Methods and Results. The results of field observations of morphodynamics of a section of the Baltic Spit sandy coast (600 m length) were analyzed. From May to November 2019, a series of measurements of the coastal zone relief were conducted. The obtained data were analyzed along with the wave regime parameters (reanalysis ERA5 data was used). The coastal profile of the area under study is complicated by the external underwater bar with its crest located at the depth 2.65 m, and by the internal one of a crescent shape. Conclusions. Analysis of displacement of the external underwater bar from May to November showed that this form was of a morphodynamics two-dimensional character, i.e. it possessed the same morphometric characteristics along the coast. It was revealed that the underwater bar crest was located at the depths close to those of wave breaking during the most recent relatively strong and sustainable storm. Based on this concept as well as on the available literature data on the relationship between a wave height and dynamics of an underwater bar crest, described is the landward displacement (recorded during the observation period) of the external underwater bar. Due to the field data, it was shown that the underwater bar morphodynamics was effected both by duration of individual waves and by difference between the wave parameters of a sequence of storm events.
Trophic Ecology of Arapaima sp. in a ria lake—river–floodplain transition zone of the Amazon

Neotropical floodplains are usually productive systems that are maintained by the nutrient, detritus and sediment inputs provided by the main river channel flood pulse. Ria lakes represent a special feature and habitat in the Amazonian floodplains, being characterised by a dendritic morphology and dependence on terrestrial inputs provided by an intricate stream network. Our objective was to evaluate the trophic ecology of the arapaima (Arapaima sp.). We combined stomach content analysis with measurements of carbon and nitrogen stable isotope values from dorsal muscle to infer the ontogenetic changes in trophic level and isotopic niche width in floodplain and ria lakes. Arapaima diet was dominated by fish from low trophic positions. While most of the stomachs sampled in the study ria lake were full, empty stomachs predominated in samples taken in the floodplain lakes. These differences indicate that ria lakes may provide better feeding grounds for arapaima during the dry season, presumably because ria lakes are interconnected with a large stream network and the main river channel year round. Nitrogen stable isotope results further indicated an ontogenetic dietary shift in arapaima, with piscivory increasing as a function of length in both environments. Carbon stable isotope analysis indicated that energy sources used by arapaima varied by environment, with arapaima using a greater diversity of food sources in ria lakes than in floodplain lakes. Information about the main carbon sources is useful for fishery management because stakeholders may choose to conserve key vegetal groups to ensure the productivity and diversity of aquatic ecosystems.
Changes in the avifauna in a high Andean cloud forest in Colombia over a 24‐year period

The upper altitude ecosystems of the Andes are among the most threatened by climate change. Computer models suggest that a large percentage of species in these ecosystems will be at risk of extinction and that avian communities will suffer disruption and impoverishment. Studies in other Andean countries lend some support to these predictions, but there are no quantitative data from Colombia appropriate to test these models. In 1991–1992, we conducted a bird survey in a high Andean cloud forest to gather information about the species present and their abundance. We attempted to replicate this earlier study 24 yr later to detect any changes in the avifauna and determine possible causes for those changes. From June 2015 to May 2016, we made bimonthly trips to the study site and identified all birds detected either visually or by voice along a number of trails. We supplemented our observational data by also capturing birds in mist-nets. Community species richness and composition as well as the overall abundance of birds changed little from 1991–1992 to 2015–2016, but nearly 30% of bird species changed in abundance. Changes in the presence or abundance of nine or 10 species reflected upward shifts in elevational limits potentially due to climate change. However, most changes in abundance appeared to reflect changes in the vegetation of the study area due to successional changes in forest and subparamo habitats and a large number of relatively recent treefalls of old canopy trees with heavy epiphyte loads and subsequent changes in the understory vegetation. Our results suggest that the effects of climate change on the avifauna in our study area at a high-altitude site in Colombia are apparently occurring more slowly than predicted by recent computer models, although we conclude that the possible effects of climate change should definitely be considered in future studies. However, single-site studies such as ours have limitations in documenting elevation shifts; the most conclusive and quantitative evidence for elevational shifts comes from long-term studies conducted over a wide range of elevations. As such, we recommend establishment of such a monitoring program in Colombia because data obtained from such a program might be important in designing measures to mitigate the effects of climate change and conserve biodiversity. © 2017 Association of Field Ornithologists
Strategy use, self-efficacy beliefs, and self-regulatedness in adult foreign language learning

The aim of this study was to understand adult learners’ strategy use in foreign language learning. It also explored how such strategy use relates to learners’ sense of self-efficacy, self-regulated learning, and language proficiency. Two questionnaires were administered to obtain data from 90 education majors in a Japanese university. Differences in strategy use in relation to self-efficacy, selfregulatedness, and proficiency were examined using Kruskal-Wallis H tests. Whilst some preferred and less preferred strategy items were identified, the findings suggested that possession of a high selfefficacy profile and self-regulatedness related to both greater use of language learning strategies and a higher level of language proficiency. However, a closer look detected a nuanced, important difference in the magnitude of the effect, whereby self-regulatedness may be more yielding than self-efficacy. Namely, self-regulatedness played a substantial role in differentiating use of several strategy items among different proficiency groups, whereas self-efficacy seems to play a smaller part than selfregulatedness in this respect, considering the effect sizes. Thus, this empirical study contributes to the ongoing discussion of the different roles and nature of the self-efficacy and self-regulatedness constructs in the context of language learning and teaching. Implications for language teaching are discussed, and directions for future research are suggested.
Impacts of UV Filters in Mytilus galloprovincialis: Preliminary Data on the Acute Effects Induced by Environmentally Relevant Concentrations

Ultraviolet (UV) filters are present in a broad range of personal hygiene products, which may be transported via aquatic environments and domestic wastewaters due to inefficient treating station sewage removal and direct human contact. The aim of the present study was to evaluate the potential effects of a UV filter, in particular benzophenone-3 (BP3) (also known as oxybenzone) on the mussel species Mytilus galloprovincialis. Mussels were exposed to this organic substance for 96 h in environmentally relevant concentrations (10, 100, and 1000 ng/L). After exposure, biomarkers related with the mussels’ metabolism and oxidative stress were evaluated. The results revealed significantly higher activity of electron transport system and energy reserves (glycogen and protein (PROT)) at the intermediate concentration of 100 ng/L, suggesting that at lower concentrations mussels’ metabolism was not activated due to low stress. Conversely, at the highest concentration (1000 ng/L), mussels were no longer able to continue to increase their metabolic activity. Higher metabolic capacity was accompanied by increased PROT content associated with increased enzyme production to activate their antioxidant system. Nevertheless, at the highest concentration, cellular damage occurred as a consequence of ineffective activation of antioxidant and biotransformation enzymes. The results of the present study address uncertainties that are fundamental to the environmental risk assessment and management of these economically important near-shore bivalves and other marine species. Although an acute exposure was performed, alterations observed indicate the negative impacts of BP3 towards marine bivalves, which could be enhanced after longer exposure periods or if mussels are simultaneously exposed to other stressors (e.g., other pollutants or climate change related factors). The present study may thus contribute to the definition of fundamental knowledge for the establishment of appropriate regulatory guidelines and practices that ensure the preservation and sustainability of biological resources, allowing for prediction and mitigation of the impacts from these compounds.
