The purpose of the research is to study the structure and severity of comorbid pathology in hospitalized patients with arterial hypertension. Material and methods. The study included 140 adult patients (29% men and 71% women) with arterial hypertension and comorbidity receiving therapy in the cardiology department. The average age of the patients was 64.3 ± 12.0 years. The Charlson index was used to assess comorbidity. Results. The average Charlson index in our study was 3.97 ± 2.0 points. Moderate and severe comorbidity was observed in 77.6% of patients with arterial hypertension. When analyzing the frequency of concomitant pathology, one disease was detected in 7% of the examined, two in 28%, three in 14%, four in 23%, five or more in 28%. The structure of concomitant pathology is represented mainly by chronic cerebral ischemia (26.3%), rhythm and conduction disturbances (20%), diseases of the bronchopulmonary (14.8%) and digestive (12.7%) systems. Analysis of risk factors for comorbidity revealed heredity aggravated by cardiovascular diseases in 33.3% of patients with arterial hypertension, smoking in 7.3%, overweight in 27%, obesity in 62%, and abdominal obesity in 87%. Obesity was not diagnosed in all men and 85.4% of women, which indicates that this risk factor for comorbidity was not taken into account. Conclusion. The introduction into the practice of managing patients with arterial hypertension and comorbidity of scoring the presence of concomitant diseases by calculating the Charlson comorbidity index will increase the accuracy of assessing the prediction of their ten-year survival. Identifying and correcting the main risk factors for comorbidity and concomitant pathology in patients with arterial hypertension can reduce disability and mortality.

Authors:   Porto Accounting and Business School, Diogo Machado,
Published: May 2021

The profitability set per customer of a given organization implies several challenges, from the calculation of the net pricing to the development of a cost allocation system within the company's main processes. Thus, the work proposed aims at exploring the potential of a customer evaluation methodology, using pricing techniques as a supporting tool, where the analysis of customer clusters will be done. We aim to identify profitability patterns, according to the customer's supply chain role, the dimension and the potential of the business, the types of transactions frame that are established, as well as the relative effects of each cluster own characteristics in the overall business relationship. After developing the methodology, the customer profitability analysis will be performed and recommendations will be set, highlighting and quantifying the possible improvements in the contribution. The use of leveraging techniques by the average and sensitivity analysis will support the recommendations. These insights will drive the companies in their pricing decisions also as shifting their focus towards attracting and retaining the customers from the more profitable clusters.
The Genetic Basis of Hypertension
Authors:   Hypertension Unit, Department of Cardiology Metaxa Cancer Hospital, Athens-Greece, Helena Michalopoulou , Foivos-Konstantinos Stamatis ,   Democritus University of Thrace
Published: May 2021

Hypertension (HTN) is one of the major risk factors for almost all cardiovascular diseases including coronary artery disease, stroke, heart failure and renal failure. Nonetheless , blood pressure (BP) regulation is insufficient due to its multifactorial nature involving interactions among genetic, environmental, mechanistic and neuroendocrine factors. Essential hypertension is the most frequent diagnosis indicating that a monocausal etiology has not been identified. The identification of causal genetic determinants has been unfulfilling. Analyses of rare monogenic syndromes of HTN focusing on renal sodium handling and steroid hormone metabolism have proved the well-defined genetic frame of hypertension though they do not affect the normal distribution of BP in the general population. Genome-wide association studies (GWAS) have revealed genetic variants that are associated with BP with small effect size which cumulatively explain to a very small extend the variability of BP. New large-scale studies in the genomic arena will clarify the polygenic determinants of BP and open a perspective on translation of the progression in BP genetics to clinical use.

The influence of the stress factor in the legal practice
Authors: Sandu Mihaela Luminita , Călin Mariana Floricica , Dragomir Rodica
Published: May 2021

Along with well known sources, we observe, for the modern person, that the work environment is a stress source who can contribute to the individual life quality deterioration. Professional stress, like it’s called in the law literature, is the stress generated from activities of work place and from the environment in which those activities occur. This type of stress can generate a multitude of atypical manifestations in a person and can have different durations correlated with the stress factors intensity. Maintaining the effects of the stress factors for long period of time can favor the somatic illnesses or even the organic ones. The explicit recommendation of specialists is to identify the most significant stress factors at the work place then take appropriate action to eradicate their causes, or, when possible to limit their effects. The law is a liberal professional, serving justice. So it’s a fact that without it as part of the judicial system, justice cannot prevail in an effective manner. Even if it’s essential to the judicial system, the law is internal to a dramatic decorum, open to threats. We cannot question the high degree of professional stress that is laid upon the members of this practice, and even the young attorneys at the beginning of their careers, who just graduated and have high dreams and strive to excel professionally, are at risk. Regrettably, with the beginning of the practice their dreams slowly dissipate, in the existential void, because of the long wait at the courthouse and the disappointment that deciding parties (judges and prosecutors) of the justice scene are imposing and impedes upon the justice spirit of the young attorneys.

International Commercial Arbitration in Malaysia
Authors: Che Rosli Iyllyana
Published: May 2021

In the recent two decades, the wave of globalisation has hit the Malaysian market. It hence contributes to the popularity of arbitration as the means to settle cross border commercial disputes. The existing literature concerned with Malaysia suggests that the recent trend in Malaysia is that arbitration has become the dominant choice of dispute resolution forum. Using qualitative and doctrinal methods, this paper seeks to analyse the regulatory framework for international commercial arbitration in Malaysia, before and after Malaysia’s accession to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards, 1958 (hereinafter, NYC 1958). The NYC 1958 is one of the most successful international treaties with 161 contracting States. The NYC 1958 aims to promote uniform practical procedures for the recognition and enforcement of foreign arbitral awards in its contracting States, irrespective seat of the awards. In doing so, the paper examines two significant periods of arbitration laws in Malaysia: pre and post-accession to the NYC 1958. The paper concludes that Malaysia no longer follows English arbitration legislation and instead follows international best practice by adopting the UNCITRAL Model Law on International Commercial Arbitration (hereinafter, UML) as the basis of its modern legislation, the Arbitration Act 2005. Malaysian courts are also seen to adopt a positive ‘pro-enforcement’ attitude in the application to recognise and enforce foreign arbitral awards, in promoting maximum enforcement of awards as promoted by the NYC 1958 and the UML.
Digital Disinformation and the Need for Internet Co-regulation in Malaysia
Authors: Daud Mahyuddin , Abd Ghani Azmi Ida Madieha
Published: May 2021

The spread of fake news on Covid19 is causing public unrest and suspicion among citizens which is a challenge for countries facing the pandemic. The misinformation or disinformation which stems from uncertainties, unrest, and anxiety because of movement control order procedures, financial and economic hardship caused wrong information to spread like fire. Called as ‘info-demic’, it becomes a second source of virulent information that requires arresting just like the pandemic itself. Controlling fake news in the time of pandemic is a daunting problem that slaps Internet regulation at its face. On the Internet, lies spreads faster than truth and correcting misinformation means tonnes of work. This paper examines Internet self- and co-regulatory approaches in selected jurisdictions to reduce the impact of fake news on governments, industry, and private actors. In applying content analysis as a qualitative research method, the first section analysed specific legislations enacted by parliaments to criminalise the acts of disseminating and publishing fake news. The second section examines legislative and administrative efforts to impose civil and criminal liability on platform providers to monitor online content. The final section analysed self-regulatory efforts to introduce online fact-checking portals and awareness campaigns. This paper argues that Internet self-regulation scheme in Malaysia is not bringing the desired result in the scope of maintaining peace and security of the nation. Considering how dangerous disinformation can cause to the society, more so in global emergency like the present Covid19 pandemic, it is submitted that Internet co-regulation is more suitable if the social, moral and cultural fabric of the society is to be maintained.

The right to health is recognised as a fundamental human right in the World Health Organisation (WHO) Constitution. In Malaysia, the enjoyment of the highest attainable standard of physical and mental health is a fundamental human right without discrimination for every human being. Consequently, the principle of the “right to health,” regardless of the legal status of an individual, is the driving force in creating acceptable standards of health care for all citizens. Even for individual who suffers from Covid-19, he still has a fundamental right to health. The issue of the right to health is whether the patients have any rights of their health? If they do have the right to health, the next issue is whether the hospitals are legally bound to follow such right, i.e. the right to health of the patients. Therefore, this paper aims to analyse and discuss the issues regarding the rights to health of the patients. Without the legal mechanism in recognising the right to health, it pointed out that is no such right. The method employed in this paper is qualitative based. The paper finds that although Malaysia does not have any specific legal framework about the right to health, the application of international legal mechanism can be referred to a guideline. Thus, it is important to have a specific legal framework by applying international legal mechanism in order to address this issue.
Integrated Prediction System for Chronic Disease Diagnosis to Ensure Better Healthcare
Authors: K. Geetha Poornima , K. Krishna Prasad
Published: May 2021

Technology innovation has made life easy for human beings. Technology is being used everywhere. This also extends to the healthcare sector. The healthcare sector produces a large amount of data each minute. Because of privacy issues, much of the data generated is not used and is not publicly accessible. Healthcare data comes from diverse sources hence it will be always varied in nature. Keeping track of such data has become much easier these days. Predictive analysis in healthcare is an emerging technology that identifies the person with poor health where the risks of developing chronic conditions are more likely and provide better solutions in the field of healthcare. Statistical methods and algorithms can be used to predict the disease before the actual symptoms are revealed in humans. By using data analytics algorithms one can easily predict chronic diseases such as obesity, high/low Blood Pressure, diabetes, asthma, cardiopulmonary disorders. Because of an unhealthy diet, lack of proper exercise, stress, consumption of tobacco, alcohol, etc. chronic diseases are most common these days. If the symptoms of chronic diseases are detected in the early stages, there will be less risk of hospitalization by cost-effectively maintaining better health. Big data analysis and health care can be mixed to produce accurate results. The application of predictive analytics in healthcare is highlighted in this paper. It provides a broader analysis in the prevention of different chronic diseases by using predictive analytics. The paper also includes various issues that arise when handling health care data. For each chronic disease, diverse models, techniques, and algorithms are used for predicting and analyzing. The paper comprises a conceptual model that integrates the prediction of most common chronic diseases

Authors: Andrade Alessandra Moraes de , Carlos Valeska Gracioso
Published: May 2021

Esta pesquisa mostra uma classificação do portunhol como língua, interlíngua, dialeto, ou outra variante, de acordo com seu contexto de uso, a partir de estudos relacionados ao tema. Partiu-se de uma pesquisa bibliográfica procurando conceitos e definições sobre língua, interlíngua, dialeto e portunhol. Posteriormente procurou-se estudos específicos de classificação do portunhol, nos quais foi constatado que esta variante pode ser classificada de acordo com os seguintes contextos: portunhol de fronteira, portunhol no contexto de ensino/aprendizado e portunhol literário. Por causa da maior concentração de estudos relacionados, o portunhol de fronteira foi limitado à fronteira Brasil – Uruguai. Quanto aos resultados, verificou-se que o portunhol de fronteira, apesar da maior parte dos estudos classificá-lo como dialeto ou variedade do português, pode ser designado como língua. O portunhol no contexto de ensino/aprendizagem, a pesar de ser considerado preferentemente uma interlíngua, pode ser considerado uma translíngua. Finalmente, com base nos estudos pesquisados, percebe-se que o portunhol literário é uma língua.

Authors: A. Nwafor Chidinma , E. Onyenwe Ikechukwu
Published: May 2021

Automatic multiple-choice question generation (MCQG) is a useful yet challenging task in Natural Language Processing (NLP). It is the task of automatic generation of correct and relevant questions from textual data. Despite its usefulness, manually creating sizeable, meaningful and relevant questions is a time-consuming and challenging task for teachers. In this paper, we present an NLP-based system for automatic MCQG for Computer-Based Testing Examination (CBTE).We used NLP technique to extract keywords that are important words in a given lesson material. To validate that the system is not perverse, five lesson materials were used to check the effectiveness and efficiency of the system. The manually extracted keywords by the teacher were compared to the auto-generated keywords and the result shows that the system was capable of extracting keywords from lesson materials in setting examinable questions. This outcome is presented in a user-friendly interface for easy accessibility.

Authors: Kwan Chiman , Gribben David , Budavari Bence
Published: May 2021

Long range infrared videos such as the Defense Systems Information Analysis Center (DSIAC) videos usually do not have high resolution. In recent years, there are significant advancement in video super-resolution algorithms. Here, we summarize our study on the use of super-resolution videos for target detection and classification. We observed that super-resolution videos can significantly improve the detection and classification performance. For example, for 3000 m range videos, we were able to improve the average precision of target detection from 11% (without super-resolution) to 44% (with 4x super-resolution) and the overall accuracy of target classification from 10% (without super-resolution) to 44% (with 2x superresolution).
Identifying and examining the nature and extent of external factors influencing growth and development of selected SMME's in Durban Kwa Zulu Natal
Authors:   , Ngubane Sisanda Michelle
Published: May 2021

This study identified and examined the nature and extent of external factors influencing growth and development of selected SMMEs in Durban, KwaZulu-Natal. The importance of the research lies in the contribution of its findings and recommendations to ensure the survival of SMMEs. The target population was identified as 300 owners of SMMEs in Durban, KwaZulu­ Natal, with a sample of 169 selected on a convenience basis, to which a questionnaire was distributed. Regardless of the problems experienced by SMMEs, it is vital to stimulate their growth and development, as this sector is likely to be the job creators of the future South Africa, as well as the providers of a continuation level of employment opportunities (Antonie, 2010). The rate at which SMMEs spring up is encouraging, considering that one of the cardinal goals of establishing SMMEs, is the eradication of unemployment and poverty. It was found that, not all of the respondents understand the potential of SMMEs to gain a competitive advantage; however, the majority agreed that Durban is an accessible and convenient location to do business, and that Government should partner with SMMEs in job creation and poverty alleviation. In addition, more than 80 percent of the respondents believe SMMEs will thrive with more access to loans and financial support. More than half of the respondents indicated that they often need to bribe government officials in the process of obtaining a business license and/or registration, while the findings also show that, when the process is fair, open and transparent, respondents believe it facilitates SMME growth and development. Recommendations on how factors identified can be better managed, so as to support, rather than negate, SMMEs' quest for growth and development, include government facilitation of workshops, and more visible training.

Emevîlere karşı Muhammed b. Ali ile başlatılan Abbâsî daveti, ardından onun oğlu İbrahim tarafından devam ettirilmiş, nihayet diğer bir oğlu olan Ebu’l-Abbâs es-Seffâh’ın Kûfe şehrinde Abbâsî ailesi adına biat almasıyla birlikte amacına ulaşmıştır. Ebu’l-Abbâs ile filizlenmeye başlayan devlet onun dört yıllık hilafet döneminde öncelikle Emevîlerin hatırasını kanlı bir şekilde silmiştir. Bu dönemde devleti sarsacak veya varlığını tehdit edebilecek boyutlarda isyanlarla karşılaşılmamıştır. Ebu’l-Abbâs’ın vefatıyla birlikte halifeliği üstlenen Ebû Cafer el-Mansûr ilk olarak isyan hareketleriyle karşı karşıya kalmıştır. Yirmi yıllık halîfeliği döneminde irili ufaklı pek çok isyan hareketiyle uğraşmak zorunda kalan Mansûr, mezkûr başkaldırıların tamamından galibiyetle ayrılması, yine devletin temellerini sağlamlaştırması sebebiyle Abbâsîlerin asıl kurucusu olarak kabul edilmiştir. Dolayısıyla Mansûr gibi bir halîfeyi tanıtacak, ayrıca döneminin belirgin özelliklerini ve hadiselerini tasvir edecek eserlere ihtiyaç vardır. Cem Zorlu’nun doktora tezi olarak hazırlanmış bu kitabı Ebû Cafer el-Mansûr dönemi isyanlarını etraflıca konu edinmektedir.

RESUMEN: El propósito de este artículo consiste en estudiar las modificaciones que lleva a cabo Francisco de Quevedo en su paráfrasis Anacreón castellano (1609), las cuales suponen la introducción de elementos elocutivos ajenos a las Anacreónticas griegas. Para ello se han identificado y analizado aquellas expresiones de los cincuenta y siete poemas en castellano que no cuentan con un antecedente en el original ni en las demás fuentes que empleó Quevedo. La inspiración hallada en estos poemas griegos y sus procedimientos estilísticos, modificados por Quevedo en su traducción castellana por medio de nuevos tropos y figuras, pudo influir también en cierta medida, como las abundantes fuentes que manejó, en su creación literaria posterior. ABSTRACT: The aim of this paper is to study Quevedo’s modifications in his paraphrase Anacreón castellano (1609), which involve the introduction of style features alien to the Greek Anacreontics. They have been identified and analysed the expressions of the fifty-seven Spanish poems that do not have any correspondence in the original neither in the other sources used by Quevedo. The inspiration found in these Greek poems and their stylistic devices, modified by Quevedo in his Spanish translation through new tropes and figures, could have influenced also to a certain extent, as well as the abundant sources that he read, in his later literary creation.

Esta investigação possui o objetivo de analisar a sustentabilidade energética do setor industrial paraense. O setor industrial envolve a produção em escala, grande mecanização e automação nos processos produtivos minerais e crescimento de produtividade. Todavia, o perfil de consumo do insumo energético compreende aspecto fundamental para se avaliar a contribuição do setor industrial ao processo de desenvolvimento sustentável no Estado do Pará. A metodologia caracteriza-se como exploratória e de natureza teórica, de maneira a se desenvolver por meio de um levantamento bibliográfico e documental. A investigação concluiu que o setor industrial paraense, apesar de sua contribuição ao Produto Interno Bruto do Pará, é insustentável energeticamente, na medida em que se utiliza de um elevadíssimo consumo de eletricidade, e ainda é responsável por grande parte das emissões de gases poluentes, oriundas de usinas hidrelétricas paraenses.
Monthly resolved modelled oceanic emissions of carbonyl sulphide and carbon disulphide for the period 2000–2019

Abstract. Carbonyl sulphide (OCS) is the most abundant, long-lived
sulphur gas in the atmosphere and a major supplier of sulphur to the
stratospheric sulphate aerosol layer. The short-lived gas carbon disulphide
(CS2) is oxidized to OCS and constitutes a major indirect source to the
atmospheric OCS budget. The atmospheric budget of OCS is not well
constrained due to a large missing source needed to compensate for
substantial evidence that was provided for significantly higher sinks.
Oceanic emissions are associated with major uncertainties. Here we provide a
first, monthly resolved ocean emission inventory of both gases for the
period 2000–2019 (available at
https://doi.org/10.5281/zenodo.4297010) (Lennartz et al.,
2020a). Emissions are calculated with a numerical box model (2.8∘×2.8∘ resolution at the Equator, T42 grid) for the oceanic
surface mixed layer, driven by ERA5 data from ECMWF and chromophoric dissolved organic matter (CDOM) from
Aqua MODIS. We find that interannual variability in OCS emissions is smaller
than seasonal variability and is mainly driven by variations in CDOM, which influences both
photochemical and light-independent production. A comparison with a global
database of more than 2500 measurements reveals overall good agreement.
Emissions of CS2 constitute a larger sulphur source to the atmosphere
than OCS and equally show interannual variability connected to variability
in CDOM. The emission estimate of CS2 is associated with higher
uncertainties as process understanding of the marine cycling of CS2 is
incomplete. We encourage the use of the data provided here as input for
atmospheric modelling studies to further assess the atmospheric OCS budget
and the role of OCS in climate.

Abstract. Long-term urban extent data are highly desirable for understanding urban land use patterns and achieving sustainable development goals. However, urban observation data based on remote sensing are typically confined to recent decades. In this study, we advance in this arena by reconstructing the urban extents for China that extend back from 15th century to 19th century based on multiple historical documents. Cities in late imperial China (the Ming and the Qing Dynasties, 1368–1911) generally had city walls, and these walls were usually built around the urban built-up area. By restoring the scope of the city walls, the urban extend in this period could be restored. Firstly, we collected the years of construction or reconstruction of city walls from the historical data. Specifically, the period in which the scope of the city wall keeps unchanged is recorded as a lifetime of it. Secondly, specialization of the scope of the city wall could be conducted based on the urban morphology method, and variety of documentation, including the historical literature materials, the military topographic maps of the first half of the 20th century, and the remote sensing images of the 1970s. Correlation and integration of the lifetime and the spatial data would produce China City Wall Areas Dataset (CCWAD) in late imperial. Based on the proximity to the time of most of the city walls, we generated China Urban Extent Dataset (CUED) in the 15th–19th centuries in six representative years (i.e., 1400, 1537, 1648, 1708, 1787, and 1866). These datasets are available at https://doi.org/10.6084/m9.figshare.14112968.v1
Combining homogeneous and heterogeneous chemistry to model inorganic compound concentrations in indoor environments: the H2I model (v1.0)
Authors: Fiorentino Eve-Agnès , Wortham Henri , Sartelet Karine
Published: May 2021

Abstract. Homogeneous reactivity has been extensively studied in recent years through outdoor air-quality simulations. However, indoor atmospheres are known to be largely influenced by another type of chemistry, which is their reactivity with surfaces. Despite progress in the understanding of heterogeneous reactions, such reactions remain barely integrated into numerical models.
In this paper, a room-scale, indoor air-quality (IAQ) model is developed to represent both heterogeneous and homogeneous chemistry.
Thanks to the introduction of sorbed species, deposition and surface reactivity are treated as two separate processes, and desorption reactions are incorporated.
The simulated concentrations of inorganic species are compared with experimental measurements acquired in a real room, thus allowing calibration of the model's undetermined parameters.
For the duration of the experiments, the influence of the simulation's initial conditions is strong.
The model succeeds in simulating the four inorganic species concentrations that were measured, namely NO, NO2, HONO and O3.
Each parameter is then varied to estimate its sensitivity and to identify the most prevailing processes.
The air-mixing velocity and the building filtration factor are uncertain parameters that appear to have a strong influence on deposition and on the control of transport from outdoors, respectively.
As expected, NO2 surface hydrolysis plays a key role in the production of secondary species. The secondary production of NO by the reaction of sorbed HONO with sorbed HNO3 stands as an essential component to integrate into IAQ models.
The surface energy balance in a cold and arid permafrost environment, Ladakh, Himalayas, India

Published: May 2021

Abstract. Recent studies have shown the cold and arid trans-Himalayan region comprises
significant areas underlain by permafrost. While the information on the
permafrost characteristics of this region started emerging, the governing
energy regime is of particular interest. This paper presents the results of
a surface energy balance (SEB) study carried out in the upper Ganglass
catchment in the Ladakh region of India which feeds directly into the
Indus River. The point-scale SEB is estimated using the 1D mode of the
GEOtop model for the period of 1 September 2015 to 31 August 2017 at 4727 m a.s.l. elevation. The model is evaluated using field-monitored snow depth
variations (accumulation and melting), outgoing long-wave radiation and
near-surface ground temperatures and showed good agreement with the
respective simulated values. For the study period, the SEB characteristics
of the study site show that the net radiation (29.7 W m−2) was the
major component, followed by sensible heat flux (−15.6 W m−2), latent
heat flux (−11.2 W m−2) and ground heat flux (−0.5 W m−2). During
both years, the latent heat flux was highest in summer and lowest in winter,
whereas the sensible heat flux was highest in post-winter and gradually
decreased towards the pre-winter season. During the study period, snow cover
builds up starting around the last week of December, facilitating ground
cooling during almost 3 months (October to December), with sub-zero
temperatures down to −20 ∘C providing a favourable environment
for permafrost. It is observed that the Ladakh region has a very low
relative humidity in the range of 43 % compared to e.g.
∼70 % in the European Alps, resulting in lower incoming
long-wave radiation and strongly negative net long-wave radiation averaging
∼-90 W m−2 compared to −40 W m−2 in the European
Alps. Hence, land surfaces at high elevation in cold and arid regions could be
overall colder than the locations with higher relative humidity, such as the
European Alps. Further, it is found that high incoming short-wave
radiation during summer months in the region may be facilitating enhanced
cooling of wet valley bottom surfaces as a result of stronger evaporation.
Pandemic Pivots: The Impact of a Global Health Crisis on the Dissertation in Practice

Published: May 2021

Five scholarly practitioners in an educational leadership for social justice doctoral program share their intentional, community-minded pivots during a global pandemic that disrupted their Dissertations in Practice (DiP). Embodying their Ed.D. program’s CPED framework (Carnegie Project on the Education Doctorate, 2019), the authors, at varying stages in the dissertation process, sought inventive solutions to COVID-19-related challenges that included the development of a new topic and research questions, adjusting study settings and participant pools, and embracing new methodologies to account for virtual-only approaches. Although uncertain how the global health crises would impact their DiP, by fostering a shared sense of community, the authors became critical friends, supporting each other in their personal, professional, and academic lives. Each narrative highlights the potential of oppositional praxis of threading identities of practice, reflection, and research–to respond creatively to the needs of their diverse research communities with compassion, vision, and agility.
