Species occurrence records are essential to understanding Earth's biodiversity and addressing global environmental issues, but do not always reflect actual locations of occurrence. Certain geographical coordinates are assigned repeatedly to thousands of observation/collection records. This may result from imperfect data management and georeferencing practices, and can greatly bias the inferred distribution of biodiversity and associated environmental conditions. Nonetheless, these ‘biodiverse’ coordinates are often overlooked in taxon‐centric studies, as they are identifiable only in aggregate across taxa and datasets, and it is difficult to determine their true circumstance without in‐depth, focused investigation. Here we assess highly recurring coordinates in biodiversity data to determine artificial hotspots of occurrences. Global. Land plants, birds, mammals, insects. We identified highly recurring coordinates across plant, bird, insect and mammal records in the Global Biodiversity Information Facility, the largest aggregator of biodiversity data. We determined which are likely artificial hotspots by examining metadata from over 40 million records, assessing spatial distributions of associated datasets, contacting data managers and reviewing literature. These results were compiled into the Artificial Hotspot Occurrence Inventory (AHOI). Artificial biodiversity hotspots generally comprised geopolitical and grid centroids. The associated uncertainty ranged from several square kilometres to millions. Such artificial biodiversity hotspots were most prevalent in plant records. For instance, over 100,000 plant occurrence records were assigned the centroid coordinates of Brazil, and points that have at least 1000 associated occurrences comprised over 9 million records. In contrast, highly recurring coordinates in animal data more often reflected actual sites of observation. AHOI can be used to (i) improve accuracy of biodiversity assessments; (ii) estimate uncertainty associated with records from artificial hotspots and make informed decisions on whether to include them in scientific studies; and (iii) identify problems in biodiversity informatics workflows and priorities for improvement.
Counseling practice exposes clinicians to the pain and suffering of others, potentially compounding their own painful life experiences. A counselor’s personal losses and illnesses can wound them; however, they can also fuel empathy for the experiences of clients. Wounded healers can be found throughout counselor education programs, even though their woundedness – for reasons of-associated with fear or stigma – may not be readily apparent or disclosed. Woundedness can be viewed along a continuum, and self-care plays a crucial part in maintaining personal and professional wellness. This article describes using a wounded healer framework, encourages cultivating a culture of wellness, and details creative ways to incorporate self-compassion into the curriculum as a preventative effort to promote intentional self-care practices. Topics and example exercises are provided.
Nuclear relaxation caused by diffusion of ¹¹¹ In/Cd probe atoms was measured in four phases having the tetragonal FeGa 3 structure (tP16) using perturbed angular correlation spectroscopy (PAC) and used to gain insight into diffusion processes in phases having more than one diffusion sublattice. The three indide phases studied in this work have two inequivalent and interpenetrating In-sublattices, labeled In1 and In2, and nuclear quadrupole interactions were resolved for probes on each sublattice. The phases are line-compounds with narrow field-widths. Diffusional relaxations, fitted using an exponential damping ansatz , were measured at the two opposing boundary compositions as a function of temperature. “High” and “low” relaxation regimes were observed that are attributed to In-poorer and In-richer compositions, under the reasonable assumption that the atomic motion occurs via an indium-vacancy diffusion mechanism. Relaxation was observed to be greater for tracer atoms starting on In2 sites in the indides immediately following decay of ¹¹¹ In into ¹¹¹ Cd, which is attributed to a preference of daughter Cd-tracer atoms and/or indium vacancies to occupy In1 sites. Activation enthalpies for relaxation are compared with enthalpies for self-diffusion in indium metal.
Amur honeysuckle (Lonicera maackii) is a widespread invasive species in North America with extensive effects on native ecosystems. Since 2012, there have been extensive outbreaks of the native leaf fungal pathogen, honeysuckle leaf blight (Insolibasidium deformans), on L. maackii. This pathogen infects leaves in the late spring/early summer and eventually kills the leaves. Our objective was to describe patterns of blight occurrence on L. maackii growing in both the forest understory and in the open in northern Kentucky, USA. Smaller shrubs had a larger fraction of blighted leaves, because they allocated more production to long shoots, which are more susceptible to leaf blight. Overall, blight occurrence was as high as 8% on the smallest shrubs, though it was an order of magnitude lower on the largest shrubs sampled. Leaf blight appears to be an emerging pathogen that fits the Pathogen Accumulation Hypothesis. We developed a growth model that suggested small (< 5 cm basal diameter) open shrubs would be most affected by blight. Thus, future work should focus on comparison of the survival and growth of small infected versus uninfected L. maackii plants, as they appear to be most affected by the leaf blight.
Females of container-breeding mosquito species use visual and chemical cues to determine suitable habitats to oviposit their eggs. Female Culex mosquitoes oviposit single egg rafts containing hundreds of eggs on the surface of water in container habitats. In this project, the effects of water volume and nutrient concentration were studied using three semi-controlled field assays to determine the role these parameters play on female Culex mosquito oviposition preference. The results of this study suggest female Culex prefer to oviposit in larger volumes of water and higher concentrations of nutrients separately, but chose intermediate conditions when presented with a combination of these two variables, which follows the Goldilocks principle. This choice may provide their offspring with optimal conditions for development by reducing intraspecific competition, thereby maximizing the biological fitness of the ovipositing Culex females.
According to the World Health Organization, Heart disease is the number one killer of humans, with coronary heart disease (CHD) being the most common type of heart disease. CHD leads to myocardial ischemia (MI) or infarction. Several clinical tests are available to assist physicians in diagnosing MI or infarcted (unhealthy) patients. However, diagnostic tests can be costly, invasive, and unreliable in identifying patients with declining coronary health conditions. This study investigated the application of Machine Learning (ML) techniques on the Vector Magnitude (VM) data of heart signals generated via Vectorcardiography (VCG) to classify unhealthy patients from healthy patients. Patients with MI, a CHD, are identified as ill patients. Three machine-learning classification techniques: Artificial Neural Networks (ANN), Support Vector Machines (SVM), and Decision Trees (DT), were applied to classify healthy and unhealthy (MI) patients. The heart signal data set was acquired from the Physikalisch-Technische Bundesanstalt (PTB) Diagnostic electrocardiogram (ECG) Database. A 10-fold cross-validation sampling method was used to improve the predictability of the sample. Results from ML techniques produced high classification sensitivity, specificity, and accuracy. ML analysis findings indicated that DT is the best predictor for classification accuracy, followed by SVM and ANN. The future study goal is to expand the study with forward-looking data and the right sample size for clinical validity and support the high accuracy results.
The job market puts pressure on marketing educators to adapt the content of their courses to current business events impacted by race, diversity, and gender issues. However, students may experience discomfort when learning about and discussing controversial topics that are not normally discussed in class. To provide tools for educators to tackle this problem, we conducted an experiment using online discussion boards, manipulating the sequence order of the questions asked to the students. A sentiment analysis offered evidence that a specific set of questions can trigger students’ personal relevance, reducing their racial priming. This will increase the students’ willingness to participate in an open discussion about race, diversity, and gender issues with their peers. The main contribution is a specific educational design that allows instructors to incorporate sensitive topics into their marketing courses without jeopardizing the classroom dynamic.
Amidst the 2019/22 COVID-19 miseries, a silver lining appears: the pandemic is causing many of us rethink our lives. Using terror management theory (TMT), this conceptual essay identifies the simultaneous emergence of two mindsets, a cautious mindset, stemming from the preservation motive, and a “virtuous” mindset, stemming from an enrichment motive—an intentionality to live a more fulfilling life. These two mindsets in turn produce five life perspectives—life themes for everyday living and achieving long-term life goals. This study reviews evidence of these five life perspectives in published reports of consumers’ thoughts during the pandemic. In turn, these emergent life perspectives and consumer motives present new opportunities for marketers to advance consumer well-being and positive social change as developed in this paper. Weaving a nexus of consumers’ emergent life perspectives, consumption motives, and marketer opportunities, our conceptual framework suggests seven research questions for marketing scholars.
The quality of impermanence between traditionalism and postmodernism gave birth to Banana’s unique “hybrid narrative”. There, people are caught between traditional values and the attraction of the postmodern lifestyle. Banana’s character loves the kitchen and has a traditional belief in ghosts but is also openly LGBT-identifying—a challenge to modern binarism that is ready to confront random postmodern disasters. The character tries to escape but still seems to be stuck in the same place. This is similar to the situation that young Japanese have to face. In the eternal struggle of life, they need to be honest, live according to their own personal values and, more importantly, always show a willingness to help others with the most practical actions. Observing the world as a whole, Banana’s novels and short stories are simultaneously new and old, and readers today are eager for her stories.
In treating care as a moral imperative, the ethics of care aims for normativity, yet its normativity is thrown into jeopardy by the fact that standards of care vary dramatically among care-givers. To counter the limitations of care ethics, I propose care aesthetics, whose success reflects measurable metrics. Rooted in ameliorative practices, care aesthetics stresses the well-being of the cared-for, whereby flourishing entails both capacity and access. Thus, care aesthetics and care ethics are distinct, since the former treats the well-being of the cared-for as proof of the “sign that our caring has been received”. To demonstrate the measurable features of well-being, I offer two concrete examples: one proposed by landscape architect Joan Iversson Nassauer and another focused on curatorial practice (curare is Latin for care). To explain why philosophers have overlooked the role of well-being in signalling the success of care, I describe how concepts such as balance, harmony, order and unity, which were originally characterised as material, became immaterial aesthetic concepts by the 20th Century. I then circle back to connect well-being to epistemology and ethics, before discussing how the goal to enhance the well-being of cared-fors and care-givers alike stands to enrich quotidian experiences.
Among older adults, aging anxiety and ageist attitudes negatively relate to one’s future time perspective. It is unclear when this pattern emerges in the lifespan. Previous research has shown that high-quality intergenerational contact is associated with reduced aging anxiety and ageist attitudes. The goal of the current study was to examine a theoretically derived model of the interrelationships between intergenerational contact, aging anxiety, ageist attitudes, and future time perspective among young adults. Results replicated the relationship between intergenerational contact, aging anxiety, and ageist attitudes with resulting implications for future time perspective.
Recent studies on information systems development have focused more on project management methods such as Agile and Kanban. These styles are often implemented at an organizational level. We study project leadership styles at an individual level to see whether different leadership styles can be employed with different types of employees and genders to improve project performance. We found that the participative style positively impacted the psychological outcome. In turn, the psychological outcome positively affected the internal efficiencies of the project. The results also showed that the participative leadership style showed a higher level of psychological satisfaction for females. The directive leadership style had an adverse effect on in-house employees but a positive effect on outsourced employees. These differences highlight how project managers should manage these groups differently to achieve desired project outcomes
We report the draft genome of cold-tolerant Pseudomonas sp. strain NKUCC02_KPG, which was isolated from a lake in Kentucky, namely, Old Alexandria Reservoir. This strain contains several genes associated with cold adaptation and is characterized by a G+C content of 58.21% and a total length of 5,187,984 bp.
On May 31, 2021, Naomi Osaka, one of the top-ranked female tennis players, and one of the highest-paid female athletes in the world, announced her withdrawal from the French Open on her social media (Twitter) account, citing mental health issues. There exists a stigma around mental health; and people suffering from mental health conditions often experience “discrimination and stigma” (World Health Organization, 2019). Such disclosures by a noted sportsperson provide an opportunity to help combat the stigma. The present study uses unsupervised machine learning and qualitative thematic analysis to analyze 11,800 English language responses to her tweet. Results indicate that Osaka’s tweet mostly garnered a lot of support and encouragement. However, there also existed some negative comments. Additionally, 40% of the negative comments were disseminated by bot-like automated accounts. Practical implications for sports communication are also discussed.
The purpose and rise of formal academic programs in gerontology at colleges and universities has been well documented over the last fifty years. What has been less well-documented is the rise of alternative pathways to gerontology training and gerontological competence, including micro-credentialing. Micro-credentials (MCs) are intended to provide quick-to-complete, competency-based education around specific topics to demonstrate relevant skills to employers. Little is known about the prevalence of micro-credentialing related to gerontology. To address this gap, we conducted an environmental scan of existing aging-related micro-credentialing opportunities. We identified 89 MCs with an explicit aging focus, applied strict inclusion criteria (narrowing the sample to 54 MCs included in the analysis), and examined the characteristics of the MCs’ scope and nature. Most MCs focused on aging-related health/disease conditions, highlighting the decline mentality underlies such training. Future efforts should entail analysis of the competencies addressed by MCs as it is critical to ensure alignment between gerontological MCs and established gerontological competencies and standards and to differentiate MCs from formal academic programs.
This chapter explores how leading Japanese print news media cover their top female and male tennis stars, Naomi Osaka and Kei Nishikori, respectively. Outlets such as the Kyodo News and The Japan Times both identify Nishikori and Osaka as Japanese first in news articles, features, and sports recaps. Most of the articles about both athletes focus on their athletic performance, which perpetuates the notion of sport as an apolitical space. That said, Osaka’s non-Japanese identity appears in later references to her, even though her multiethnic identity would not be of much relevance in stories focused on her on-court performance. Osaka’s physical appearance definitely grabbed the attention of the Japanese public, and the press needed to account for it when she was new to the Women’s Tennis Association, but it has persisted to this day, which is likely because she does not meet the definition of Japanese in the popular consciousness. Moreover, Osaka’s outspokenness forces Japanese news media to also cover social justice issues, complicating the idea of sport as apolitical. On the other hand, Nishikori’s noncontroversial coverage extends to off-the-court life in that Japanese news media largely ignore Nishikori’s personal life, in stark contrast to Osaka.KeywordsJapanNaomi OsakaKei NishikoriTennisThematic analysis
