Impact of Survey Design Features on Score Reliability
Authors: Miller Brian K. , Simmering Marcia
Published: December 2020

The a priori impact of survey design and implementation tactics on score reliability is not well-understood. Using a two-by-two-by-two cluster randomized post-test only experimental design, the Cronbach’s coefficient alpha of internal consistency reliability of scores on three personality scales is calculated. The experimental conditions are presence versus absence of quality control items, anonymous versus confidential administration conditions, and randomly scrambled items versus grouped survey items. Alpha was calculated for each of the eight treatment groups. Hakstian and Whalen’s (1976) formulae were used to calculate the standard deviation of alpha. These summary data were then used in analysis of variance tests. The ANOVA results were mixed for the three personality scales. The use of quality control items had no impact on alpha on any scale, confidentiality improved alpha on one scale and decreased it on two others, and grouping items together improved alpha on two scales and decreased it on another. Although most of the exploratory interaction tests for each scale were statistically significant, none were in the direction implied by the confluence of main effect hypotheses. These mixed results suggest that a priori machinations by survey designers and administrators may often result in unwanted differences in score reliability.
Applying the Model Penal Code Insanity Defense to Sleepwalking Killers and Psychopaths
Authors: Xiaoyi Xu April
Published: December 2020

The American legal system currently tends to excuse sleepwalking killers, particularly based on the involuntary act defense, more so than the insanity defense. By contrast, the law generally does not excuse psychopathic murderers. However, the status quo may not be the optimal or most just solution to this legal dilemma; depending on one’s philosophical beliefs regarding the tension between society’s interest and the accused’s rights, one can identify various flaws within the prevailing application of the insanity defense in cases involving sleepwalking and psychopathy. As the law is constantly evolving, there is space for growth in this area, especially with the advancement in neuroscience, which can offer more insight into sleepwalkers’ and psychopaths’ brains.

In approaching the complex questions of whether and how the law should excuse sleepwalking killers and psychopaths from punishment, this article turns to relevant findings from neuroscience for support and focuses on one particular approach, that of the Model Penal Code (MPC) insanity defense. We begin with an overview of the relevant criminal law doctrine in contextualizing the MPC’s approach to insanity defense. We then apply the relevant MPC section, § 4.01, to the sleepwalking killer and psychopath contexts, bearing in mind relevant studies and findings in neuroscience and related scientific disciplines, as well as their limitations at this stage. Part of the analysis considers the U.S. Supreme Court’s latest insanity law decision, Kahler v. Kansas (2020), in relation to the subject matter of this article.
HYPOXIA AND REPRODUCTIVE HEALTH: Hypoxic regulation of preimplantation embryos: lessons from human embryonic stem cells
Authors: Houghton Franchesca D
Published: December 2020

Development of the preimplantation embryo is reliant on nutrients present in the milieu of the reproductive tract. While carbohydrates, amino acids, lipids, and micronutrients are often considered when discussing preimplantation embryo nutrition, environmental oxygen is frequently overlooked. Although oxygen is not classically considered a nutrient, it is an important component of the in vitro culture environment and a critical regulator of cellular physiology. Oxygen is required to sustain an oxidative metabolism but when oxygen becomes limited, cells mount a physiological response driven by a family of transcription factors termed ‘hypoxia inducible factors’ which promote expression of a multitude of oxygen sensitive genes. It is this hypoxic response that is responsible not only for the switch to a glycolytic metabolism but also for a plethora of other cellular responses. There has been much debate in recent years over which environmental oxygen tension is preferential for the culture of preimplantation embryos. The review will evaluate this question and highlights how research using human embryonic stem cells can inform our understanding of why culturing under physiological oxygen tensions may be beneficial for the development of embryos generated through clinical in vitro fertilisation.
Comparación del desempeño de jóvenes en pruebas neuropsicológicas en formato lápiz y papel e informatizadas
Authors: Brandwayn Natalia , Restrepo David , Macías-Bohórquez Ricardo , López-López Wilson , Acevedo-Triana César
Published: December 2020

Los campos de la aplicación de pruebas psicológicas y neuropsicológicas se han visto impactos por la tecnología específicamente con las pruebas informatizados. Una de las preguntas frecuentes en versiones papel y lápiz comparadas con una versión informatizada de la misma prueba, es si éstas  son equivalentes. El objetivo de este estudio fue comparar el desempeño de pruebas neuropsicológicas en formato lápiz y papel y formato computarizado. Participaron 41 estudiantes en dos aplicaciones de las mismas pruebas en las dos versiones. Se encontró que los desempeños fueron equivalentes en la mayoría de las pruebas. Sin embargo, existen variaciones en las modalidades dependiendo de la ejecución de la prueba y con alta variabilidad entre sujetos. Esto sugiere que la diferencia en las puntuaciones podría deberse a la diferencia en los procesos cognitivos subyacentes a la ejecución de las dos modalidades.

Die Bedeutung des Unternehmertums - Was Keynes und Schumpeter verbindet
Authors: Hecker Christian
Published: December 2020

Obwohl die Theorien von Keynes und Schumpeter zumeist als gegensätzlich wahrgenommen werden, finden sich v.a. hinsichtlich der Wertschätzung des Unternehmertums wesentliche Übereinstimmungen. So konnte der Kapitalismus aus Sicht von Keynes und Schumpeter nur dann dauerhaft funktionieren, wenn vorausschauende Unternehmer durch Investitionen und Innovationen langfristiges Wachstumspotential schufen. Vor diesem Hintergrund lassen sich wesentliche Elemente der jüngsten Finanzmarktkrise nicht zuletzt auf einen Verfall des Unternehmertums zurückführen.

El análisis comparativo entre razas de gallinas mediterráneas en base a sus características morfológicas no refleja relaciones de origen ni aptitud
Authors: Parés-Casanova P. M. , Berenguer-Boix J.
Published: December 2020

El objetivo del estudio fue realizar la clasificación sistemática de grupos afines y con base a semejanzas morfológicas de 19 razas de gallinas del grupo mediterráneo. Estas fueron 15 españolas (Alicantina, Andaluza Azul, Cara Blanca, Castellana Negra, Empordanesa, Flor d’Ametller, Mallorquina, Menorquina, Murciana, Pairal, Penedesenca, Prat, Sobrarbe, Utrerana y Valenciana de Chulilla) y cuatro italianas (Italiana, Livorno, Mericanel della Brianza y Paduana) a partir de 17 características morfológicas cualitativas. Se evaluaron con base al principio de parsimonia usando el método de Fitch. El filograma resultante, interpretado como un árbol de grupos concernientes a las relaciones morfológicas entre las razas estudiadas y no como un árbol filogenético, ya que no permite la agrupación de las razas en función de su origen o aptitud. Ello, junto con los índices obtenidos de sinapomorfia –caracteres homólogos compartidos– y homoplasia –cambios paralelos adquiridos independientemente–, más elevado en el primero, permite suponer que, aunque en el proceso de diversificación de la gallina se hayan podido dar fenómenos de convergencia de caracteres morfológicos, han sido mayores los fenómenos de conservación de caracteres morfológicos ya existentes. Es decir, que se han dado cambios en los modelos morfológicos en el proceso de formación de las razas, independientes de su origen y aptitud.

Se realizó la descripción histológica de los folículos ováricos de paiche de 12, 18 y 24 meses de edad de una piscifactoría en Iquitos en mayo de 2018, con base a un muestreo de conveniencia. Se trabajó con 9, 13 y 4 ovarios de paiches de 12, 18 y 24 meses, respectivamente. Se desarrolló una clasificación folicular con base a las características foliculares y con base a esto, se determinó la proporción folicular ovárica, los diámetros foliculares y el porcentaje de atresia folicular. Se consideraron las siguientes fases: Perinucleolar (PN), Vitelogénesis I endógena (VE1), Vitelogénesis endógena II (VE2) y Vitelogénesis exógena (VEX). La mayor frecuencia de folículos PN se presentó a la edad de 12 meses (p<005), no habiendo diferencias significativas en la frecuencia de folículos VE1 a los 18 y 24 meses. Las etapas VE2 y VEX solo se observaron a los 24 meses. No se encontró diferencia significativa en el porcentaje de atresia entre edades. Los resultados obtenidos sugieren que las hembras tienen características aparentes compatibles con el inicio de un ovario en maduración avanzada a partir de los 24 meses de edad.

Tafsir Nusantara dan Isu-isu Global: Studi Kasus Relevansi Pemikiran Hamka tentang Keadilan Sosial, Kesetaraan Gender dan Pluralisme
Authors: Aziz Thoriqul , Abidin Ahmad Zainal , Nafiah Muthmainnatun
Published: December 2020

This article discusses the relevance of Hamka's thought in Tafsir al-Azhar pertaining to global issues in modern life. Hamka is an Indonesian Muslim scholar who is well recognized. He is a modernist interpreter who writes his tafsir in Indonesian. With a descriptive-analytical method, this study reveals the contribution of Hamka's thinking in the three most challenging global domains in Muslim scholarship on issues of social justice, gender equality and religious plurality. From his thoughts it can be concluded: First, in the realm of social justice; according to Hamka, all humans have the same rights and degrees in the social and legal perspective. Second, in the realm of gender equality; men and women have equal right and there is no difference in the realm of humanity. Third, in the realm of religious plurality, Hamka believes that there is plurality in diversity. Therefore, tolerance is a necessity for every human being. The three themes carried by Hamka are based on the teachings of Islam that are very concerned about human values. Hamka's interpretation above confirms the teachings of Islam which are apropriate for all times.

Authors: Singh Varinder , Kumar Amit
Published: December 2020

Background: The study was aimed to determine the mechanism of antioxidant effects of Glycyrrhiza glabra L. (GG) roots using in-vitro assays.Methods: The various extracts of GG roots were prepared and evaluated for DPPH scavenging, reducing effects and nitric oxide inhibiting activities. Prepared extracts were screened for the presence of various phytochemicals and quantified on the basis of phytochemical present therein.Results: The results showed that all the prepared extracts contained phenolic compounds. Also, extract showed appreciable antioxidant effects in all three assays employed. However, among prepared extracts, ethylacetate extract was found to have strong free radical inhibition, ferric reducing potential and nitric oxide inhibitory effects. The reason for high antioxidant activity in ethylacetate extract could be attributed to the significant amount phenol compounds present in it. Conclusion: Evidently, GG’s capacity to scavenge free radicals, reducing potential and inhibit nitric oxide contributes to its antioxidant effects and thus, could be a strong candidate for developing antioxidant based drug therapy.
Immunologic Properties of Human Milk and Clinical Implications in the Neonatal Population
Authors: Young Lauren , McGuire William
Published: December 2020

Human milk contains various bioactive substances including hormones, immunoglobulins, enzymes, and growth factors in addition to its macro- and micronutrients. It has been suggested that human milk is a vehicle of communication between the maternal and infant immune systems, providing passive protection as well as direct active immunomodulation. Human milk protects newborns against pathogens by acting directly on multiple physiologic systems. Bioactive and immunologic factors regulate the infant's immune, metabolic, and microbiome systems. Breastfeeding protects infants in all socioeconomic groups, showing a pattern of protective dose/duration-response effects. This review summarizes the immune components and immunologic properties of human milk and provides an update of their potential implications in the neonatal population.
Application of Biological Nitrogen Fixation Cyanobacteria To Paddy Plant Cultivated Under Deep-Water Culture System

Published: December 2020

The Biological Nitrogen Fixing (BNF) cyanobacteria can reduce atmospheric nitrogen into ammonium. This ability makes BNF cyanobacteria a potential eco-friendly N-source for soil-planted pad-dy. Apart from a few success stories of BNF cyanobacteria applica-tion in the rice field, its role as an ammonium producer is still an open question. There is also a possibility that indeed cyanobacteria biomass which provides nitrogen through the biological decomposing process. This study aimed to analyze the influence of three strains BNF cyanobacteria on paddy grown in the Deep-Water Culture (DWC) hydroponic system. Yoshida Nutrient Solution was used as a growth medium with the application of 0, 45.7, and 91.4 gL-1 of ammonium nitrate (NH4NO3) with five replications. The result showed that inter-action between cyanobacteria and nitrogen significantly influenced the total nitrogen of paddy plant, but not the paddy plant height, the num-ber of tillers, and biomass. Cyanobacterial filaments were found most-ly attached to the paddy root rather than floated in the DWC system. Paddy treated with cyanobacteria had more lateral root than control. The result suggested that cyanobacteria support paddy growth indi-rectly through nitrogen deposition in plant tissue and root development.
Life-cycle assessments of solar water-heating systems: a review
Authors: Wei Lili , Guo Xiujuan , Zhang Lina
Published: December 2020

This research study reviews life-cycle assessments (LCAs) of solar water-heating systems (SWHS) and provides a complete overview of its progress. Several research papers have confirmed the advantages of SWHS in energy saving and environmental protection, but the reported system performances varied greatly, due to climate, raw materials and the systematic design. The environmental impacts are mainly caused by the manufacturing and acquisition of raw materials, whose values vary depending on the forms of the system and the materials. The users also have great influence on the performance, but there are few studies regarding this and optimisation should be made accordingly. LCAs highly depend on the implication background, including the energy structure and industrial production technologies. Whether to choose solar energy or not needs life-cycle analysis according to local conditions.
Experimental assessment of the small-strain response of residual soil under monotonic and cyclic loading
Authors: Carretta Mariana da Silva , Cristelo Nuno , Festugato Lucas , Miguel Gustavo Dias , Consoli Nilo Cesar
Published: December 2020

Residual soil from the Passo Fundo region (Brazil), presents natural cementation, responsible for a peculiar behaviour that is clearly distinguishable from that of soils with other origins. Understanding this behaviour and the effects of the fabric, with an influence on the cementation bonding, is essential to characterise these materials. Therefore, the aim of the present study is the mechanical characterisation of this soil, mainly by analysis and testing of remoulded and undisturbed samples. The experimental programme included uniaxial compressive strength tests, oedometer tests, consolidated drained monotonic triaxial tests and consolidated undrained cyclic triaxial tests. Based on the data collected, a clear influence of interparticle bonding, provided by the natural cementation, was detected on the soil's intrinsic behaviour; the undisturbed material showed a higher stiffness modulus than the remoulded material, mainly due to the bond breakage to which the latter was submitted, losing its natural cementation. A uniaxial confining stress of 89.4 kPa was obtained for the undisturbed material, assumed to be its yield stress. This value was corroborated by the oedometric (87.5 kPa), isotropic (80 kPa) and triaxial compression (90 kPa). The natural cementation was influential in every type of loading and should be considered during the design process.

Published: December 2020

ABSTRACT The need to increase self-sufficiency of rural agricultural systems has been a centre of focus for many extension programs aimed at rural development and improved livelihoods. Numerous biotic, abiotic and socio-economic factors affect maize production for resource poor farmers in the Eastern Cape (EC), which is one of the poorest Provinces in South Africa. Focus group discussions and semi-structured questionnaires were used to identify farmer characteristics, and specific production constraints influencing maize productivity in Jixini and Mkhwezo villages, of O. R. Tambo District in the EC Province. Elderly farmers who are above 56 years dominated the studied farming communities. The predominant varieties used were local landraces (53%) followed by hybrids (31%) and improved open pollinated varieties (OPVs) (11%). Farmers preferred local landraces as they were considered more palatable. Unmarried farmers were the least productive farmer group due to shortages of labour, use of landrace varieties and inadequate fertilizer. The main production constraints faced by farmers, were too much rain, pests and diseases infestation, drought stress due to climate change, and lack of fencing of the out-fields. Increasing the involvement of youths in agricultural activities could improve maize productivity. Maize breeding programs should solicit information on farmer-preferred traits and incorporate them into the improved varieties to enhance their desirability and adoption. Targeting of varieties should be guided by the most common constraints affecting maize productivity in a specific location rather than issuing blanket recommendations. Additionally, agricultural extension programs could improve their service delivery by having good knowledge of target-farmer traits, their farming practices and prevailing constraints. Information in this manuscript can go a long way in improving extension service delivery in the EC Province of the country.

Mixotrophy - Quantification of the percent of phytoplankton cells with preys (e.g. fluorescent microspheres or fluorescently labeled bacteria) v1
Authors: Jimenez Valeria
Published: December 2020

This methodology describes a protocol modified from Sherr and Sherr (1993) to determine phytoplankton prey uptake using flow cytometry and yellow-green fluorescent polystyrene-based microspheres (YG-beads; 0.5 µm in diameter, Fluoresbrite, Polysciences, Inc., Warrington, PA, USA) or fluorescently labelled bacteria (FLBs) as food proxies. FLBs were prepared according to the protocol of Sherr et al. (1987) using the bacteria Brevundimonas diminuta (strain CECT313, also named Pseudomonas diminuta), obtained from the Spanish Type Culture Collection (CECT, Valencia, Spain). The percent of cells with prey were measured in the laboratory in four Micromonas polaris strains and one mixotrophic strain (Ochromonas triangulata) used as a positive control. The percent of cells with beads was determined in samples fixed with Lugol's iodine solution (protocol explained in detail here) and enumerated with a flow cytometer (Guava easyCyte, Luminex Corporation, USA) where cells that contained chlorophyll as well as green fluorescence (same signal as the prey added, YG-beads or FLBs) were considered to be cells containing prey (quantification protocol explain in detail here). To determine the uptake of prey over time the percent of cells with preys was quantified in each experimental flask by first adding preys and then sub-sampling and fixing after an incubation of 0 (T0), 20 (T20) and 40 (T40) minutes. The T0 sample accounts for the physical attachment of preys to the cell and therefore the percent of cells ingesting prey corresponds to the percent of cells with prey at T20 or T40, minus the percent of cells with prey at T0.

DAMPING OF THE AXISYMMETRIC RESONANT VIBRATION AND DISSIPATIVE HEATING OF THE FIXED SHEAR COMPLIANT INELASTIC CYLINDRICAL SHELL WITH PIEZOACTUATOR
Authors: Zhuk Y. , Tarasov A.
Published: December 2020

Damping problem for axisymmetric resonant vibration of the shear compliant inelastic cylindrical shell with piezoactuator under electromechanical monoharmonic excitation is considered. The problem is solved for the refined problem statement accounting for shear strain, rotation inertia and thermal dependence of the material properties. Problem statement is based on the application of the amplitude constitutive relations for cyclically deformed material and complex moduli concept. The moduli for both piezoactive and piezopassive material are considered to be the functions of temperature. The nonlinear problem is solved numerically with the use of the iterative approach. The possibility of active damping of the forced vibration by means of the piezoactivator with account of shear strain is studied.

Um ator influente com interesse em modelos educativos estrangeiros: José Maria Eugénio de Almeida (1811-1872)
Authors: Manique da Silva Carlos
Published: December 2020

O presente artigo contextualiza a ação educativa de um prestigiado membro da elite económica e política portuguesa de meados do século XIX – José Maria Eugénio de Almeida (1811-1872). Enfatizando a circulação internacional do conhecimento, revela-se o interesse que os sistemas educativos dos Estados alemães suscitam a Eugénio de Almeida. As viagens pedagógicas que realiza a alguns desses Estados alicerçam o processo de renovação pedagógica que terá lugar na Casa Pia de Lisboa – instituição assistencial que lidera entre 1859 e 1872. No fundo, aquilo que se pretende conhecer é o impacto que esse “contacto” (estrangeiro) tem no sistema existente. Verdadeiramente, o posicionamento concetual é o de perceber como uma realidade (a da Casa Pia de Lisboa) é pensada em função de um referente estrangeiro. Por outras palavras, na linha da investigação de Mary S. Morgan, significa que no contexto de receção há acomodação e adaptação do conhecimento. No entanto, a sua integridade não é posta em causa.

Background Public trust in the healthcare professions has declined in recent years. The United States ranks among the lowest in terms of public trust in their physicians. Higher levels of trust in one’s primary care provider (PCP) have been associated with improved patient outcomes. Most studies involving trust among healthcare practitioners focused mainly on its conception. Little is known on what attributes of PCPs affects trust. Objectives The purpose of this study is to describe the impact of dual degreed healthcare providers on patient trust. Secondary objectives includes identification of a) any additional PCP attributes that may affect patient trust. And b) which additional degrees may impact level of patient trust. Methods A cross-sectional study evaluating the impact of dual degrees on public trust of their physician or non-physician providers (NPP). Participants were given a questionnaire regarding their perception on their PCP and whether that would change if possessed an additional degree. Survey was comprehensive in nature, focusing on current perception on their PCP’s demographics, level of communication, education, and overall qualifications, and which factors would be affected if they had an additional degree. Results A total of 279 participants responded to the survey. Roughly 55 percent of respondents indicated their PCP’s level of care (n = 154) and communication (n = 152) would be improved if they had an additional degree. 58 percent (n = 163) believed that their level of trust in their PCP would increase if they had an additional degree. These differences were not found to be statistically significant. However, more respondents that saw a physician as their PCP felt an additional degree would make a positive impact on their trust (p-value = 0.019) and perception of care (p-value = 0.020) received by their PCP than those that saw an NPP. Conclusion Overall, this study found that an additional degree impacts patient perception on trust in addition to communication and level of care received from their PCP. Also, the years of experience, where their education was received, and continuity of care has an impact on patient trust. Further study involving how to impact patient trust with their PCP may prove to be beneficial and ultimately lead to increased reputation and marketability.

Authors: Fucili Eliana , Terranova David
Published: December 2020

Este trabajo busca realizar un aporte a la historia social de la justicia a través de enfoques y metodologías sujetos a la actual agenda de investigación sobre las instituciones estatales. Puntualmente, se propone presentar un análisis sobre cómo estaba organizada la justicia de paz en el territorio mendocino entre 1872-1890, un periodo en el que se dictaron las primeras leyes que regularon la administración de la justicia baja en la provincia. En efecto, durante esos años la fisonomía del poder judicial local adquirió mayor cohesión como resultado del desarrollo político e institucional del poder central y provincial. Asimismo, el trabajo centra su atención en quiénes fueron los actores que ejercieron los fueros de paz en la provincia, atendiendo principalmente, a sus perfiles socioocupacionales.
Consecuencias demográficas de dos epidemias coloniales en las familias de Taximaroa
Authors: González Flores José Gustavo
Published: December 2020

En este artículo se analiza la incidencia de las epidemias de matlazáhuatl de 1738-1739 y el tifo de 1813-1814, así como sus consecuencias al interior de las unidades familiares desde el caso de la parroquia de Taximaroa en el obispado de Michoacán. Para lograrlo se recurrió al análisis de las partidas de entierros mediante el método de conteo anónimo (agregativo) de reconstrucción de familias. Se concluye que las epidemias de tifo afectaban predominantemente a la población adulta y sus consecuencias fueron más radicales que la viruela o el sarampión, ya que desarticulaban casi por completo a las familias con la muerte del padre, de la madre o de ambos.

Authors: Zuo Tongzhuo
Published: December 2020

Occupational diseases are disorders of health resulting from conditions related to the workplace. There are 2.3 million deaths annually for reasons attributed to work globally, primarily to chemicals or dust. China has the largest working population in the world, with 776 million employed in 2018. According to the National Health Commission, about 12 million companies were found to have occupational-disease-inductive factors and at least 200 million people are exposed to occupational disease hazards. Preventing occupational diseases is a serious worldwide challenge. On the other hand, many developed countries already have rich experience in the prevention and treatment of various occupational diseases. They have set up various occupational disease prevention agencies and formulated strict occupational disease prevention systems. It is necessary for developing countries to learn from their advanced control measures.

On English Listening Learning Strategies for College Students
Authors: Zhang Xiaomei
Published: December 2020

In recent years, the reform of college education and teaching introduced by the state has achieved remarkable results, and college English curriculum has been repositioned as an important course. Oral English is one of the important contents of college students’ foreign communication. As a second language, the environment of English teaching lags behind Chinese, which is very difficult for contemporary college students to master oral English skills. Especially the English listening part is the premise for college students to understand oral English, and the quality of listening ability directly affects the ability of college students to understand English. Although the English teaching reform has increased the content of listening training to some extent, it is due to the difference of language environment and learning. The platform is backward, the listening effect of college students is still unsatisfactory. Based on the present situation of college students’ listening, this paper discusses how to effectively reform and improve the effect of college students’ English listening learning.

Published: December 2020

The impact of floods on the migration activity of elements coming from urbanized territories to the Amur river was assessed. The influence of large cities on pollution of water and floodplain ecosystems is revealed. The content of heavy metals in water, bottom sediments, and small watercourses draining urban areas is characterized. The processes of sediment accumulation in the floodplain, their influence on the redistribution of elements and geochemical transformations in the soil space of floodplain soils are studied. Conditions for the accumulation of heavy metals in soils are described, their concentration levels and migration activity are determined. The role of organic matter in swamps and silts on water pollution and bottom sediments of the Amur river is shown. It was found that the main mass transfer of soluble substances and pollutants dispersed fractions of nailc is carried out by water flow during floods.

As indicações dadas pelo Em Si ôntico configuram diretivas precisas e indicam a melhor escolha em cada situação, bem como as mudanças pessoais impactadas pelos jovens.
Leading with meaning: Why diversity, equity, and inclusion matters in U. S. higher education
Authors: Barnett Rachel
Published: December 2020

In Academic Leadership and Governance of Higher Education, Hendrickson, Lane, Harris, and Dorman (2013) argue that institutional decisions, adaptations, and activities of successful academic leaders need to be mission and value-focused.  Academic institutions value autonomy and expertise in decision-making, which necessitates that academic leaders “create and foster democratic partnerships with myriad constituents” (Hendrickson et al., 2013: 2) and organize their activities around a shared vision based on institutional mission and values.  In this paper, I review some recent research findings that demonstrate the need to address issues of diversity, equity, and inclusion in U. S. higher education contexts as educators work to transform students into responsible citizens.  These findings highlight the need for academic leaders to consider how to best embody the mission and vision of their institutions as they frame diversity issues for the campus community, with a few additional considerations specific to religiously affiliated institutions.
