A Cross-National Study of Ethical School Culture
Authors: Shapira-Lishchinsky Orly
Published: February 2020

This study addresses a common concept, ethical school culture, in 30 countries. It presents and outlines its dimensions, based on an analysis of their codes of ethics for teachers. The findings generated a multi-dimensional model of ethical school culture that included six dimensions: caring for the pupils, teachers' profession, teachers' collegial relationships, parental involvement, community involvement, and respecting rules and regulations.

The study indicated that “ethical school culture” generates from the interaction between the formal ethical aspects, such as educational policy that encourages high standards, and informal ethical aspects, such as ethical norms that perceive teachers’ role modeling as important for maintenance of the profession’s status. In addition, the findings elicited that schools with an ethical culture are not closed educational systems but rather open educational systems that ensure that knowledge will flow from the school to the community and vice versa. This flow of knowledge is in accordance with the ethical goals that advance equity and opportunity for all pupils.

Moreover, the similarity that exists between the dimensions in this study and the dimensions in the corporate ethical virtues (CEV) model expand conceptual validity to the generated multidimensional model. In general, this study reveals that schools have an ethical culture characterized by a teachers’ active approach toward promoting their pupils’ ongoing learning and well-being, initiating collaborative learning with colleagues, and promoting parental involvement.

This study generated the common meaning of ethical culture in schools, based on teachers’ interactions with colleagues, pupils, parents, community, and regulations. Understanding the meaning of an ethical culture in schools, can help promote ethical teachers, who will know what is expected from an ethical teacher and help promote an ethical culture in their schools. In addition, the findings of this study support the universal nature of the concept ethical school culture and provide deeper insight into the concept of ethical culture in educational systems. This study hopes to encourage the promotion of teachers’ continuing professional development, which focuses on the proposed six dimensions that can lead to a consistently applied ethical school culture.
Cognitive Science and Educational Administration
Authors: Evers Colin W. , Lakomski Gabriele
Published: February 2020

The influence of cognitive science on educational administration has been patchy. It has varied over four main accounts of cognition, which are, in historical order: behaviorism, functionalism, artificial neural networks, and cognitive neuroscience. These developments, at least as they may have concerned educational administration, go from the late 1940s up to the present day. There also has been a corresponding sequence of developments in educational administration, mainly motivated by accounts of the nature of science. The goal of producing a science of educational administration was dominated by the construal of science as a positivist enterprise. For much of the field’s early development, from the 1950s to the early 1970s, varieties of behaviorism were central, with brief excursions into functionalism. When large-scale alternatives to behaviorism finally began to emerge, they were mostly alternatives to science, and thus failed to comport with much of cognitive science. However, the emergence of postpositivist accounts of science has created the possibility for studies in administrator cognition to be informed by developments in neuroscience. These developments initially included the study of artificial neural networks and more recently have involved biologically realistic mathematical models that reflect work in cognitive neuroscience.
Micropolitics in School Leadership
Authors: Lindle Jane Clark
Published: February 2020

The concept of micropolitics in schooling originated in the latter part of the 20th century and contrasted macropolitical analyses of central ministries’ directives, primarily in English-speaking education systems, with more localized forms of governance, as in the United States. Either form of educational governance envelops daily interactions among governmental agencies, school personnel, and stakeholders. As political scientists long have studied macropolitics, sociologists and educationists focused on micropolitics found in schools’ short- and long-term decisions. Typical decisions, which generate micropolitics, include how schools carry on teaching and learning and range from formalized policy implementation to negotiations over scarce resources as big as allocation of teacher–pupil ratios and as momentary and small as distribution of paper and pencils. Given its local focus, scholars of micropolitics assume that the conditions of schooling generate and sustain persistent conflict, and thus they study how such conflict surfaces, who participates, who wins or loses, and what roles school leaders play. Conflicts surround schools’ internal and external communities’ power structures. The power players, groups and individuals, contest the purposes of schooling and work to influence their agenda. These influential moves may reshape macro-policies and directives, making policy implementation a localized project. Internal and external constituencies struggle over resource allocation, frequently under conditions of scarcity, which provides an arena for investigating decision participation. As with studies in macropolitics, the methods vary with the research questions. Because of the high-engagement dynamics in the study of micropolitics in schools, discursive methods that focus on communications, relationships, and media dominate these studies.
Social Justice Leadership, Equity, and the Digital Divide
Authors: Normore Anthony H. , Issa Lahera Antonia
Published: February 2020

To commit to Brown v. Board of Education’s legacy of advancing social justice and democracy, it is necessary to look at practices (i.e., the types of discourse, experiences, processes, and structures) that promote the development and support of school leaders committed to social justice, equity, access, and diversity. Leadership preparation programs need to provide the knowledge base for aspiring school leaders to understand how they ought to respond to the changing political, moral, and social landscapes in which they live and work. Of equal importance is the curricular focus on interrelating social justice, democracy, equity, and diversity so that aspiring school leaders can identify practices that explicitly and implicitly deter social progress. Furthermore, these school leaders ought to be able to develop a knowledge base on how to respond to these injustices in their school leadership practices.

As leadership development and preparation program personnel prepare new leaders, the discourse of social justice and marginalization is an important objective in the curriculum of preparation programs. Personnel in leadership programs have an opportunity to take part in discourse about how to shape the quality of leaders they produce for the good of society. To this end, researchers offer critical insights into the types of discourse, experiences, processes, and structures that promote the development and support of contemporary principals committed to social justice and democratic principles. Included in the research discussion are the tenets of social justice leadership, democracy, diversity and the digital divide, digital access, and digital equity.
Moral Dimensions of Leadership
Authors: Davidson Frank D. , Hughes Thomas R.
Published: February 2020

The development of moral and ethical leadership in practicing and aspiring leaders is essential for the success of educational institutions. Leaders demonstrate moral and ethical leadership through striving to act in a manner reflective of the best interests of students. Such leadership is guided by a personal vision reflecting values such as integrity, fairness, equity, social justice, and respect for diversity. These qualities are reflected in the 2015 Professional Standards for Educational Leaders published by the National Policy Board for Educational Administration. One’s understanding of moral and ethical leadership can be strengthened by seeing the connections between moral leadership and the related themes of transformational leadership, authentic leadership, and trust in leaders. School leaders can help to create ethical schools by developing and being guided by a vision-driven professional ethos, manifesting that ethos in interactions with others, engaging staff in the co-creating of a vision-driven school, and through advocacy in the larger community.
Leading Through Conflict With Credibility
Authors: Hughes Thomas R. , Davidson Frank D.
Published: February 2020

Even though conflict is increasingly finding its way into school settings, there is evidence that school leaders do not view themselves as being adequately equipped to meet the growing challenges. Training on short-term approaches to dealing with immediate issues may be available to practitioners through professional development offerings, but there is more involved in successfully and sustainably dealing with conflict than getting through a tense moment. School leaders need to be able to understand the causes and complexities—as well as navigate time elements—associated with ongoing conflict that can take place at the personal as well as organizational levels. Beyond understanding these concepts, administrators themselves need to increase the capacity of their staff and their organizations to assist in their development.

In addition to learning how to recognize patterns and underlying causes advancing adversity, administrators would do well to invest in long-term conflict diminishing approaches such as building trust and improving interpersonal and organizational capacity as ways to increase credibility within and outside of the school itself. Finding people who can think critically and work adaptively to solve problems could prove to be a real advantage for educational leaders who strive to reduce the stress of the workplace and create a more collegial climate within the schools they serve. Building trust and the ability to “come through” capably for others even in tough situations increases the credibility of leaders. Leading through conflict with this credibility in turn helps to sustain a positive climate in schools.
Global Health Diplomacy: A Theoretical and Analytical Review
Authors: Almeida Celia
Published: February 2020

The end of the Cold War brought far-reaching world changes in many areas, including the health field. A number of “new” terms emerged (such as global health, global governance, and global health governance or global governance for health), among them global health diplomacy (or health diplomacy). There is no single, consensual definition of this term, and still less are there theoretical and analytical frameworks or empirical data to help understand its meaning and practice more clearly. Global health diplomacy is a sociopolitical practice involving the global health policy community, which promotes the interrelationship between health and foreign policy both at the national level, through cooperation projects or international actions and, in international arenas, by acting in global political space in the widest range of spheres, whether health-sector-related or otherwise.
Repressive Legislation: Slave Codes, Northern Black Laws, and Southern Black Codes
Authors: Middleton Stephen
Published: February 2020

Beginning in the 1630s, colonial assemblies in English America and later the new United States used legislation and constitutions to enslave Africans and deny free blacks civil rights, including free movement, freedom of marriage, freedom of occupation and, of course, citizenship and the vote. Across the next two centuries, blacks and a minority of whites critiqued the oppressive racialist system. Blacks employed varied tactics to challenge their enslavement, from running away to inciting revolts. Others used fiery rhetoric and printed tracts. In the 1760s, when whites began to search for political and philosophical arguments to challenge what they perceived as political oppression from London, they labeled their experience as “slavery.” The colonists also developed compelling arguments that gave some of them the insight that enslaving Africans was as wrong as what they called British oppression. The Massachusetts lawyer James Otis wiped the mirror clean in The Rights of the British Colonies Asserted and Proved, stating “The colonists, black and white . . . are free-born British subjects . . . entitled to all the essential civil rights.” The Declaration of Independence polished the stained mirror by asserting, “We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights.” However, the Constitution of the United States negated these gains by offering federal protection for slavery; it was a covenant with death, as abolitionist William Lloyd Garrison later asserted. After the Revolution, many states passed black laws to deprive blacks of the same rights as whites. Blacks commonly could not vote, testify in court against a white, or serve on juries. States barred black children from public schools. The Civil War offered the promise of equality with whites, but when the war ended, many southern states immediately passed black codes to deny blacks the gains won in emancipation.
Working-Class Anti-Unionism
Authors: Caldemeyer Dana M.
Published: February 2020

Unlike the anti-unionism that runs through the ranks of employers, worker anti-unionism describes the workers who are opposed to or who work against unionization. Anti-union actions can be seen throughout the United States from the early industrial age forward and include anything from refusing to join the union or follow union orders, to fighting against the union, such as with strikebreaking. Workers’ reasons for acting against the union, however, are far more complex, including the economic gains that come from remaining outside the union, moral opposition to unionism, and spite against the union. The variations between workers’ reasons for rejecting the union, then, provide insight into how workers define their place in society as well as their relationship with the union.
Morphological Units: A Theoretical and Psycholinguistic Perspective
Authors: Sandra Dominiek
Published: February 2020

Speakers can transfer meanings to each other because they represent them in a perceptible form. Phonology and syntactic structure are two levels of linguistic form. Morphemes are situated in-between them. Like phonemes they have a phonological component, and like syntactic structures they carry relational information. A distinction can be made between inflectional and lexical morphology. Both are devices in the service of communicative efficiency, by highlighting grammatical and semantic relations, respectively. Morphological structure has also been studied in psycholinguistics, especially by researchers who are interested in the process of visual word recognition. They found that a word is recognized more easily when it belongs to a large morphological family, which suggests that the mental lexicon is structured along morphological lines. The semantic transparency of a word’s morphological structure plays an important role. Several findings also suggest that morphology plays an important role at a pre-lexical processing level as well. It seems that morphologically complex words are subjected to a process of blind morphological decomposition before lexical access is attempted.
Psycholinguistic Methods and Tasks in Morphology
Authors: Schmidtke Daniel , Kuperman Victor
Published: February 2020

Lexical representations in an individual mind are not given to direct scrutiny. Thus, in their theorizing of mental representations, researchers must rely on observable and measurable outcomes of language processing, that is, perception, production, storage, access, and retrieval of lexical information. Morphological research pursues these questions utilizing the full arsenal of analytical tools and experimental techniques that are at the disposal of psycholinguistics. This article outlines the most popular approaches, and aims to provide, for each technique, a brief overview of its procedure in experimental practice. Additionally, the article describes the link between the processing effect(s) that the tool can elicit and the representational phenomena that it may shed light on. The article discusses methods of morphological research in the two major human linguistic faculties—production and comprehension—and provides a separate treatment of spoken, written and sign language.
Head Movement and Morphological Strength
Authors: Zwart Jan-Wouter
Published: February 2020

In the Principles and Parameters framework of Generative Grammar, the various positions occupied by the verb have been identified as functional heads hosting inflectional material (affixes or features), which may or may not attract the verb. This gave rise to a hypothesis, the Rich Agreement Hypothesis (RAH), according to which the verb has to move to the relevant functional head when the corresponding inflectional paradigm counts as “rich.”

The RAH is motivated by synchronic and diachronic variation among closely related languages (mostly of the Germanic family) suggesting a correspondence between verb movement and rich agreement. Research into this correspondence was initially marred by the absence of a fundamental definition of “richness” and by the observation of counterexamples, both synchronically (dialects not conforming to the pattern) and diachronically (a significant time gap between the erosion of verbal inflection and the disappearance of verb movement). Also, the research was based on a limited group of related languages and dialects. This led to the conclusion that there was at best a weak correlation between verb movement and richness of morphology.

Recently, the RAH has been revived in its strong form, proposing a fundamental definition of richness and testing the RAH against a typologically more diverse sample of the languages of the world. While this represents significant progress, several problems remain, with certain (current and past) varieties of North Germanic not conforming to the expected pattern, and the typological survey yielding mixed or unclear results. A further problem is that other Germanic languages (Dutch, German, Frisian) vary as to the richness of their morphology, but show identical verb placement patterns.

This state of affairs, especially in light of recent minimalist proposals relocating both inflectional morphology and verb movement outside syntax proper (to a component in the model of grammar interfacing between narrow syntax and phonetic realization), suggests that we need a more fundamental understanding of the relation between morphology and syntax before any relation between head movement and morphological strength can be reliably ascertained.
Non-Governmental Organizations and Natural Hazard Governance in Asia and the Pacific
Authors: Rowlands Allison , Wisner Benjamin
Published: February 2020

International non-governmental organizations (INGOs), national nongovernmental organizations (NNGOs), as well as faith-based and community-based organizations play a vital role in natural hazard governance in Asia and the Pacific. One immediately thinks of humanitarian response, and, indeed, these organizations can and do play a role; however, as some Asian nations in particular have developed strong state institutions and have grown in their worldwide and regional economic and political status, civil society’s role has diversified. Among the other functions the nongovernmental sector plays in the mobilization of local people and advocacy for or against policies, it is involved in investment decisions as well as acts as a watchdog regarding the status of human rights in relation to natural hazard exposure and recovery and transparency in the use of disaster risk reduction and recovery funds. This diverse collection of nongovernmental institutions also has a role in knowledge production and access and innovates programs that showcase how governments might break down silos and put action behind the rhetoric of taking an intersectoral, multihazard, integrated approach that combines risk reduction, climate change adaptation (CCA), and livelihood enhancement. Indeed, nongovernmental actors also push for societal transformation as they work on issues of discrimination, inequity, electoral transparency, and human rights. These issues are among the root causes of the structural vulnerability of some groups in society to natural hazards. While governments in the region sometimes welcome these supplementary and complementary roles by INGOs and NNGOs, they are also a source of government–nongovernmental tension that has to be negotiated.
Ancient and Traditional Agriculture in South America: Tropical Lowlands
Authors: Shepard Glenn H. , Clement Charles R. , Lima Helena Pinto , Mendes dos Santos Gilton , Moraes Claide de Paula , Neves Eduardo Góes
Published: February 2020

The tropical lowlands of South America were long thought of as a “counterfeit paradise,” a vast expanse of mostly pristine rainforests with poor soils for farming, limited protein resources, and environmental conditions inimical to the endogenous development of hierarchical human societies. These misconceptions derived largely from a fundamental misunderstanding of the unique characteristics of ancient and indigenous farming and environmental management in lowland South America, which are in turn closely related to the cultural baggage surrounding the term “agriculture.”

Archaeological and archaeobotanical discoveries made in the early 21st century have overturned these misconceptions and revealed the true nature of the ancient and traditional food production systems of lowland South America, which involve a complex combination of horticulture, agroforestry, and the management of non-domesticated or incipiently domesticated species in cultural forest landscapes. In this sense, lowland South America breaks the mould of the Old World “farming hypothesis” by revealing cultivation without domestication and domestication without agriculture, a syndrome that has been referred to as “anti-domestication”. These discoveries have contributed to a better understanding of the cultural history of South America, while also suggesting new paradigms of environmental management and food production for the future of this critical and threatened biome.
Integrative systematics untangles the evolutionary history ofStenochrus(Schizomida: Hubbardiidae), a neglected junkyard genus of North American short-tailed whipscorpions
Authors: Monjaraz-Ruedas Rodrigo , Francke Oscar F , Prendini Lorenzo
Published: February 2020

Until recently, the Nearctic short-tailed whipscorpion genus, StenochrusChamberlin, 1922, included 27 species distributed primarily in Mexico, the USA and Central America. Morphological disparity among its species, associated with their adaptation to diverse habitats, raised the question as to whether Stenochrus was monophyletic. The phylogenetic relationships among short-tailed whipscorpions have only recently begun to be explored, and the monophyly of Stenochrus had never been tested. The present contribution provides the first phylogeny of Stenochrus and related genera, based on 61 morphological characters and 2991 aligned DNA nucleotides from two nuclear and two mitochondrial gene markers, for 73 terminal taxa. Separate and simultaneous analyses of the morphological and molecular data sets were conducted with Bayesian Inference, Maximum Likelihood, and parsimony with equal and implied weighting. Terminals represented only by morphological data (‘orphans’) were included in some analyses for evaluation of their phylogenetic positions. As previously defined, Stenochrus sensuReddell & Cokendolpher (1991, 1995) was consistently polyphyletic and comprised eight monophyletic clades, justifying its reclassification into eight genera including Heteroschizomus Rowland, 1973, revalidated from synonymy with Stenochrus by Monjaraz-Ruedas et al. (2019). Rowland & Reddell’s (1980)mexicanus and pecki species groups were consistently paraphyletic. Orphans grouped with the most morphologically similar taxa.
The epidemiology of osteoporosis

Published: February 2020

Introduction

With a worldwide ageing population, the importance of the prevention and management of osteoporotic fragility fractures is increasing over time. In this review, we discuss in detail the epidemiology of fragility fractures, how this is shaped by pharmacological interventions and how novel screening programmes can reduce the clinical and economic burden of osteoporotic fractures.

Sources of data

PubMed and Google Scholar were searched using various combinations of the keywords ‘osteoporosis’, ‘epidemiology’, ‘fracture’, ‘screening’, `FRAX’ and ‘SCOOP’.

Areas of agreement

The economic burden of osteoporosis-related fracture is significant, costing approximately $17.9 and £4 billion per annum in the USA and UK.

Areas of controversy

Risk calculators such as the web-based FRAX® algorithm have enabled assessment of an individual’s fracture risk using clinical risk factors, with only partial consideration of bone mineral density (BMD).

Growing points

As with all new interventions, we await the results of long-term use of osteoporosis screening algorithms and how these can be refined and incorporated into clinical practice.

Areas timely for developing research

Despite advances in osteoporosis screening, a minority of men and women at high fracture risk worldwide receive treatment. The economic and societal burden caused by osteoporosis is a clear motivation for improving the screening and management of osteoporosis worldwide.
Safety of early discharge with a chest tube after pulmonary segmentectomy
Authors: Bao Feichao , Dimitrovska Natasha Toleska , Hu Shoujun , Chu Xiao , Li Wentao
Published: February 2020

OBJECTIVES

Early removal of chest tube is an important step in enhanced recovery after surgery protocols. However, after pulmonary resection with a wide dissection plane, such as pulmonary segmentectomy, prolonged air leak, a large volume of pleural drainage and the risk of developing empyema in patients can delay chest tube removal and result in a low rate of completion of the enhanced recovery after surgery protocol. In this study, we aimed to assess the safety of discharging patients with a chest tube after pulmonary segmentectomy.

METHODS

We retrospectively reviewed a single surgeon’s experience of pulmonary segmentectomy from May 2019 to September 2019. Patients who fulfilled the criteria for discharging with a chest tube were discharged and provided written instructions. They returned for chest tube removal after satisfactory resolution of air leak or fluid drainage.

RESULTS

In total, 126 patients underwent pulmonary segmentectomy. Ninety-five (75%) patients were discharged with a chest tube postoperatively. The mean time to chest tube removal after discharge was 5.6 (range 2–32) days, potentially saving 532 inpatient hospital days. Overall, 90 (95%) patients experienced uneventful and successful outpatient chest tube management. No life-threatening complications were observed. No patient experienced complications resulting from chest tube malfunction. Five (5%) patients experienced minor complications. Overall, all patients reported good-to-excellent mobility with a chest tube.

CONCLUSIONS

Successful postoperative outpatient chest tube management after pulmonary segmentectomy can be accomplished in selected patients without a major increase in morbidity or mortality.
Multitrophic interactions in the rhizosphere microbiome of wheat: from bacteria and fungi to protists

Published: February 2020

Plants modulate the soil microbiota by root exudation assembling a complex rhizosphere microbiome with organisms spanning different trophic levels. Here, we assessed the diversity of bacterial, fungal and cercozoan communities in landraces and modern varieties of wheat. The dominant taxa within each group were the bacterial phyla Proteobacteria, Actinobacteria and Acidobacteria; the fungi phyla Ascomycota, Chytridiomycota and Basidiomycota; and the Cercozoa classes Sarcomonadea, Thecofilosea and Imbricatea. We showed that microbial networks of the wheat landraces formed a more intricate network topology than that of modern wheat cultivars, suggesting that breeding selection resulted in a reduced ability to recruit specific microbes in the rhizosphere. The high connectedness of certain cercozoan taxa to bacteria and fungi indicated trophic network hierarchies where certain predators gain predominance over others. Positive correlations between protists and bacteria in landraces were preserved as a subset in cultivars as was the case for the Sarcomonadea class with Actinobacteria. The correlations between the microbiome structure and plant genotype observed in our results suggest the importance of top-down control by organisms of higher trophic levels as a key factor for understanding the drivers of microbiome community assembly in the rhizosphere.
Evolutionary Analysis of the Zinc Finger and Homeoboxes Family of Proteins Identifies Multiple Conserved Domains and a Common Early Chordate Ancestor
Authors: Nail Alexandra N , Smith Jeramiah J , Peterson Martha L , Spear Brett T
Published: February 2020

The Zinc Fingers and Homeoboxes (Zhx) proteins, Zhx1, Zhx2, and Zhx3, comprise a small family of proteins containing two amino-terminal C2–H2 zinc fingers and four or five carboxy-terminal homeodomains. These multiple homeodomains make Zhx proteins unusual because the majority of homeodomain-containing proteins contain a single homeodomain. Studies in cultured cells and mice suggest that Zhx proteins can function as positive or negative transcriptional regulators. Zhx2 regulates numerous hepatic genes, and all three Zhx proteins have been implicated in different cancers. Because Zhx proteins contain multiple predicted homeodomains, are associated with interesting physiological traits, and seem to be only present in the vertebrate lineage, we investigated the evolutionary history of this small family by comparing Zhx homologs from a wide range of chordates. This analysis indicates that the zinc finger motifs and homeodomains are highly similar among all Zhx proteins and also identifies additional Zhx-specific conserved regions, including a 13 amino acid amino-terminal motif that is nearly identical among all gnathostome Zhx proteins. We found single Zhx proteins in the sea lamprey (Petromyzon marinus) and in the nonvertebrate chordates sea squirt (Ciona intestinalis) and lancelet (Branchiostoma floridae); these Zhx proteins are most similar to gnathostome Zhx3. Based on our analyses, we propose that a duplication of the primordial Zhx gene gave rise to Zhx3 and the precursor to Zhx1 and Zhx2. A subsequent tandem duplication of this precursor generated Zhx1 and Zhx2 found in gnathostomes.
Entrepreneurship and the firm: a conversation on foundations and prospects
Authors: Foss Nicolai J , Grandori Anna
Published: February 2020

Entrepreneurship has emerged as a major research theme across a number of disciplines and fields, including the industrial dynamics tradition. Entrepreneurship is often seen as closely linked to firms and firm formation. However, the links between economic organization and entrepreneurship are unclear. Do entrepreneurs always need firms to realize their plans? If so, why? Can firms be “entrepreneurial”? If so, what is the difference between an entrepreneurial and a non-entrepreneurial firm? More broadly, how can entrepreneurship be informed by the theory of the firm and vice versa? These foundational issues in both the theory of the firm and the field of entrepreneurship have not been resolved. This dialogue between two scholars who have worked at the intersection of entrepreneurship and the theory of the firm for more than 20 years addresses such key questions as: What is the meaning of “uncertainty” and what is its role? What are the features and roles of resources? How are resources linked to property rights and the firm? On what basis can we say that firms differ in the extent to which they are “entrepreneurial”?
Moulding the ideal crab: implications of phenotypic plasticity for crustacean stock enhancement
Authors: Daly Benjamin J , Eckert Ginny L , Long W Christopher
Published: February 2020

Numerous examples of behavioural and morphological differences between hatchery-cultured and wild individuals exist for a range of crustacean species; however, we submit that these variances are not deficiencies, but rather are adaptive responses to an unnatural rearing environment that may be detrimental in the natural environment. This phenotypic plasticity could be beneficial for stock enhancement because such plasticity suggests potential for change with adjustments to rearing protocols to achieve improved ecological competence. We examine how specific plastic responses can affect crustacean ecology through effects on predation, foraging, competition, and reproduction. For developing stock enhancement programmes, we recommend consideration of plastic phenotypic patterns before large-scale releases are initiated. Researchers can identify environmental factors that cue plasticity during hatchery rearing, determine if induced responses are ecologically influential after release into the wild, and examine the temporal scale on which phenotypic plasticity operates. Communal hatchery rearing at low-to-medium stocking densities with predator cues and natural substrates along with in situ conditioning, releases during periods of low predation risk, and coupled laboratory-field studies can contribute to improved ecological performance during stock enhancement. Finally, presentation of non-significant research results is needed to avoid bias towards hatchery–wild differences and help guide future conditioning programmes.
Prevalence of Burnout in Breast Imaging Radiologists
Authors: Parikh Jay R , Sun Jia , Mainiero Martha B
Published: February 2020

Objective

Burnout is defined as a psychological syndrome arising as a response to chronic prolonged interpersonal job-related stress. Physician burnout has been increasingly recognized over the past decade as an epidemic within the United States. The goal of this study was to ascertain the prevalence of burnout amongst practicing breast imaging radiologists.

Methods

A survey contained demographic questions based on workforce surveys carried out by the American College of Radiology and a validated condensed version of the Maslach Burnout Inventory (MBI) evaluating the three aspects of burnout. The radiologist members of the Society of Breast Imaging (SBI) received the survey internally from the SBI as a weekly e-mail with a web link to the survey from February 19, 2019, to March 13, 2019. The link allowed respondents to complete the survey anonymously. The authors were blinded to the SBI mailing list and the SBI was blinded to the responses.

Results

A total of 370 breast imaging radiologists from the SBI responded to the survey. Overall, 290 out of 370 (78.4%) were highly burned out in at least 1 measured dimension of burnout; 197 out of 362 (54.4%) were highly burned out in at least 2 dimensions of burnout; and 27 out of 362 (7.5%) were highly burned out in all 3 dimensions of burnout. However, rates of personal accomplishment were high, with only 8.8% experiencing high burnout in the dimension of personal accomplishment.

Conclusion

Our study demonstrates a high prevalence of burnout amongst breast imaging radiologists. Burnout rates were highest in the youngest breast imaging radiologists.
Preferences and Attitudes Regarding Adjunct Breast Cancer Screening Among Patients with Dense Breasts
Authors: Miller Matthew M , Repich Kathy , Patrie James T , Anderson Roger T , Harvey Jennifer A
Published: February 2020

Objective

New breast screening modalities are being investigated to address the need for more sensitive breast cancer screening in women with dense breasts. We investigated the preferences and attitudes of these patients regarding adjunct screening modalities to help evaluate the acceptability of these exams.

Methods

In this institutional review board–approved prospective study, patients with dense breasts on their prior mammogram were invited to complete a survey. Patients were asked to estimate their personal breast cancer risk compared with peers, indicate their level of concern related to screening callbacks, radiation exposure, and intravenous (IV) contrast allergies, and identify which factors might deter them from getting adjunct screening exams.

Results

Five hundred eight patients with dense breasts presenting for screening mammography completed surveys. While most patients (304/508, 59.9%) felt it was likely or very likely that cancer could be missed on their mammogram, only 8.9% (45/508) had undergone adjunct screening exams in the past 3 years. The most commonly cited deterrents to adjunct screening were cost (340/508, 66.9%), pain (173/508, 34.1%), and concern that adjunct screening could lead to additional procedures (158/508, 31.1%). When asked to select among three hypothetical breast cancer screening modalities, patients strongly preferred the more sensitive examination, even if this involved greater cost (162/508, 31.9%) or IV-contrast administration (315/508, 62.0%).

Conclusion

Our data suggest that patients with dense breasts prefer adjunct screening exams that are both sensitive and inexpensive, although an increase in sensitivity could outweigh additional cost or even IV-line placement.

COVID-19 outbreak on the Diamond Princess cruise ship: estimating the epidemic potential and effectiveness of public health countermeasures
Authors: Rocklöv J , Sjödin H , Wilder-Smith A
Published: February 2020

Background

Cruise ships carry a large number of people in confined spaces with relative homogeneous mixing. On 3 February, 2020, an outbreak of COVID-19 on cruise ship Diamond Princess was reported with 10 initial cases, following an index case on board around 21-25th January. By 4th February, public health measures such as removal and isolation of ill passengers and quarantine of non-ill passengers were implemented. By 20th February, 619 of 3700 passengers and crew (17%) were tested positive.

Methods

We estimated the basic reproduction number from the initial period of the outbreak using SEIR models. We calibrated the models with transient functions of countermeasures to incidence data. We additionally estimated a counterfactual scenario in absence of countermeasures, and established a model stratified by crew and guests to study the impact of differential contact rates among the groups. We also compared scenarios of an earlier versus later evacuation of the ship.

Results

The basic reproduction rate was initially 4 times higher on-board compared to the ${R}_0$ in the epicentre in Wuhan, but the countermeasures lowered it substantially. Based on the modeled initial ${R}_0$ of 14.8, we estimated that without any interventions within the time period of 21 January to 19 February, 2920 out of the 3700 (79%) would have been infected. Isolation and quarantine therefore prevented 2307 cases, and lowered the ${R}_0$ to 1.78. We showed that an early evacuation of all passengers on 3 February would have been associated with 76 infected persons in their incubation time.

Conclusions

The cruise ship conditions clearly amplified an already highly transmissible disease. The public health measures prevented more than 2000 additional cases compared to no interventions. However, evacuating all passengers and crew early on in the outbreak would have prevented many more passengers and crew from infection.
Disentangling modal meanings with distributional semantics
Authors: Hilpert Martin , Flach Susanne
Published: February 2020

This article investigates the collocational behavior of English modal auxiliaries such as may and might with the aim of finding corpus-based measures that distinguish between different modal expressions and that allow insights into why speakers may choose one over another in a given context. The analysis uses token-based semantic vector space modeling (Heylen et al., 2015, Monitoring polysemy. Word space models as a tool for large-scale lexical semantic analysis. Lingua, 157: 153–72; Hilpert and Correia Saavedra, 2017, Using token-based semantic vector spaces for corpus-linguistic analyses: From practical applications to tests of theoretical claims. Corpus Linguistics and Linguistic Theory) in order to determine whether different modal auxiliaries can be distinguished in terms of their collocational profiles. The analysis further examines whether different senses of the same auxiliary exhibit divergent collocational preferences. The results indicate that near-synonymous pairs of modal expressions, such as may and might or must and have to, differ in their distributional characteristics. Also, different senses of the same modal expression, such as deontic and epistemic uses of may, can be distinguished on the basis of distributional information. We discuss these results against the background of previous empirical findings (Hilpert, 2016, Construction Grammar and its Application to English, 2nd edn. Edinburgh: Edinburgh University Press, Flach, in press, Beyond modal idioms and modal harmony: a corpus-based analysis of gradient idiomaticity in modal-adverb collocations. English Language and Linguistics) and theoretical issues such as degrees of grammaticalization (Correia Saavedra, 2019, Measurements of Grammaticalization: Developing a Quantitative Index for the Study of Grammatical Change. PhD Dissertation, Université de Neuchâtel) and the avoidance of synonymy (Bolinger, 1968, Entailment and the meaning of structures. Glossa, 2(2): 119–27).
Interpretation of metaphors in Chinese poetry: Where did Li Bai place his emotions?
Authors: Peng Ciyuan , Jung Jason J
Published: February 2020

Recently, with an increasing number of metaphor studies being conducted, research on metaphor interpretation has set off an upsurge. Although a multitude of studies on the interpretation of metaphors exists, many are limited to the understanding of literal meanings without attempting an interpretation of hidden emotions in metaphorical expressions. There are particularly few studies on metaphorical emotions interpretation in literary studies with rich and implicit emotions, such as classical Chinese poetry. This study proposes the interpretation of the metaphorical emotions of special objects in Chinese poetry based on emotion distribution. We present a statistical approach to calculate the emotion distribution of our target objects by exploiting contextual emotion mining. According to the emotion distribution, the emotion with the highest probability is considered the metaphorical emotion of the target object. Subsequently, the metaphorical emotion can be determined as a positive or negative sentiment based on expert annotations. Using the proposed method, we have tested two representative objects, ‘月’ (moon) and ‘风’ (wind), and the accuracy performances were 84% and 83.33%, respectively, for sentiment detection and 66% and 70% for emotion-specific metaphorical interpretation. The results demonstrate that our approach can be used to assist readers with metaphorical emotional understanding in Chinese poetry.
Defence against the modern arts: the curse of statistics: Part I—FRStat
Authors: Neumann Cedric
Published: February 2020

For several decades, legal and scientific scholars have argued that conclusions from forensic examinations should be supported by statistical data and reported within a probabilistic framework. Multiple models have been proposed to quantify and express the probative value of forensic evidence. Unfortunately, the use of statistics to perform inferences in forensic science adds a layer of complexity that most forensic scientists, court offices and lay individuals are not armed to handle. Many applications of statistics to forensic science rely on ad hoc strategies and are not scientifically sound. The opacity of the technical jargon that is used to describe these probabilistic models and their results, and the complexity of the techniques involved make it very difficult for the untrained user to separate the wheat from the chaff. This series of article is intended to help forensic scientists and lawyers recognize limitations and issues in tools proposed to interpret the results of forensic examinations. This article focuses on the tool proposed by the Latent Print Branch of the U.S. Defense Forensic Science Center (DFSC) and called FRStat. In this article, I explore the compatibility of the results outputted by FRStat with the language used by the DFCS to report the conclusions of their fingerprint examinations, as well as the appropriateness of the statistical modelling underpinning the tool and the validation of its performance.

Comprehensive understanding of aberrant splicing in gastric cancer is lacking. We RNA-sequenced 19 gastric tumor–normal pairs and identified 118 high-confidence tumor-associated (TA) alternative splicing events (ASEs) based on high-coverage sequencing and stringent filtering, and also identified 8 differentially expressed splicing factors (SFs). The TA ASEs occurred in genes primarily involved in cytoskeletal organization. We constructed a correlative network between TA ASE splicing ratios and SF expression, replicated it in independent gastric cancer data from The Cancer Genome Atlas and experimentally validated it by knockdown of the nodal SFs (PTBP1, ESRP2 and MBNL1). Each SF knockdown drove splicing alterations in several corresponding TA ASEs and led to alterations in cellular migration consistent with the role of TA ASEs in cytoskeletal organization. We have therefore established a robust network of dysregulated splicing associated with tumor invasion in gastric cancer. Our work is a resource for identifying oncogenic splice forms, SFs and splicing-generated tumor antigens as biomarkers and therapeutic targets.
Congenital nephrotic syndrome as a complication of whooping cough: a case report

Bordetella organisms are responsible for whooping cough, which is an extremely contagious respiratory illness with substantial morbidity in infants. It is also considered one of the 10 predominant reasons for childhood decease globally, particularly before vaccination was available. Congenital nephrotic syndrome (CNS) presents within the first 3 months of life. It is classified as primary or as secondary to other etiologies, such as infections, drug reactions, toxins, mercury exposure, diabetes mellitus and autoimmune diseases. This article describes the rare presentation of CNS as an outcome to Bordetella infection. That is treating pertussis resulted in CNS to resolve, so it was classified as secondary. This case is the first documented in Syria and the second worldwide.
