Being Dr. Jekyll And Mr. Hyde: Role-Based Identity Foils In Organizational Life, Blake E. Ashforth, Beth S. Schinoff, Kristie M. Rogers, Donald Lange

Management Faculty Research and Publications

Soldier-medic. Undercover police officer. Collaborative divorce attorney. Certain jobs require an individual to enact antithetical sets of role expectations (to do X and not-X), such as saving a life and taking a life, in the case of a soldier-medic. Despite their important consequences, we lack a unifying framework for such antithetical expectations and their implied identity foils—where one is expected to be both Dr. Jekyll and Mr. Hyde (a life-saver and a life-taker). To this end, we build theory on how and why antithetical expectations and their implied identity foils arise in organizations. We offer a model …

Lessons of 3 different classes, at different schools and in different years were used. An investigation lesson from …

The Assessment-Related Logics Of Practice At A South West Multi-Academy Trust, Samuel Gordon Morahan

Plymouth Institute of Education Theses

Over the last 40 years there have been widescale changes to the British education system. Through the process of neoliberalisation, education has become a commodity to be bought and sold with an ever-increasing emphasis on performativity and its related measures. Within this educational market, alternative provision settings provide commissioning schools with opportunities to purchase placements and packages for pupils, who for a variety of reasons, are unable to engage in mainstream education. Alternative provision settings must evidence value for money to these schools, whilst meeting statutory inspection requirements. Assessment practices and the numerical data they generate are central within this …

A Rare Case Of Cold Agglutination Syndrome Secondary To Mycoplasma Pneumoniae, Dr.Disha Shahri, Dr. Srinath K. M, Dr. Basava Chethan, Dr. Savitha Vijayakumar, Dr. Meghna B.S.

Digital Journal of Clinical Medicine

Mycoplasma pneumoniae (M. pneumoniae) is one of the foremost causes of community acquired pneumonia. Most of the cases are, however mild. Although, complications may seldom occur. One such known complication of M. pneumoniae infection is cold agglutinin hemolysis, which is usually benign and transient. This hemolysis is due to formation of cold agglutinins during the course of infection. Cold Agglutination Syndrome (CAS) is a type of acquired Autoimmune Hemolytic Anaemia (AIHA), which exists due to an underlying disorder, like a viral illness or lymohoid malignancy. It is generally self-remitting, in contrast to Cold Agglutination Disease (CAD), which is a chronic …

Augustinian Composition Pedagogy And The Catholic Liberal Arts In The Time Of Generative Ai, Gavin F. Hurley

Journal of Catholic Education

This article proposes a theoretical basis of Augustinian composition pedagogy by tracing the symbiotic relationship between writing and knowing found within St. Augustine’s Letters, The Trinity, Soliloquies, and Confessions and connecting them to modern writing-to-learn composition pedagogies. Given today’s trying times of generative AI, this article argues that Catholic schools revitalize the writing arts in a manner proposed by Augustine—that is, to enrich inward contemplation and outward love for others. In embracing such philosophy of writing and applying it across the disciplines, Catholic schools can enrich their distinctively Catholic liberal arts mission—and ward off dangers found in …

These religious symbols, which are used in palace buildings and generally in administrative places in the Islamic world, are shaped depending on the function of the buildings. In this period, the palace complexes were considered to be the most important structures representing state politics and economy. In this study, the purposes and methods of use of religious symbols used in many palace complexes of Islamic architecture were investigated. While investigating the main source and usage rules of …

The Model Of Desire And Fear As An Invariant In Literature, Melake Agasaf Elyasova-Rajabova

Khazar Journal of Humanities and Social Sciences

The issue of the projection of the desire and fear model in literature is analyzed from different perspectives in this research. Desire and fear along with forming a dichotomy together, complement each other. Sometimes the feeling of fear turns into a barrier in front of the feeling of desire, whereas, the feeling of fear sometimes saves him (her) from taking some wrong steps. Humans are born as biological beings, but they are formed as social beings. Each person is formed through the relationship between the individual and society; he acts taking into account the stereotypes of the society - the …

The Purpose And Importance Of Words Of Knowledge When Praying For The Sick, Bruce L. Bauer

Journal of Adventist Mission Studies

Seventh-day Adventists are not usually known for taking authority over sickness or taking a person by the hand and saying, “In the Name of Jesus of Nazareth, arise and walk.” And rightly so, for Adventists have been counseled that when praying for the sick “our prayers must take the form, not of command, but of intercession” (White 1942:230, 1915:218). Why, because only God knows what is right and best (White 1948:148, 149). In addition, Ellen White warns against prayers that insist on God doing what people think needs to happen (1948:148) and suggests that God’s people should only pray for …

The Emotional Side Of Teaching Conceptions: Exploring The Relationship Between Conceptions Of Teaching And Teacher Burnout, Well-Being, And Resilience, Marc Clarà, Alba Vallés, Sílvia Cavalcante, Aina Franch, Jordi Coiduras, Patricia Silva, Nick Kelly, Tatiana López, Priscila Marchán, Bárbara Padula

Australian Journal of Teacher Education

This paper investigates the relationship between teachers’ conceptions of teaching and several indicators of their emotional experience. With a sample of 200 teachers, the study identifies three dimensions of teaching conceptions, “student-centeredness,” “educational purpose,” and “projection into the future.” Statistical analysis revealed that student-centeredness is negatively correlated with teachers’ resilience and well-being. Additionally, we found that well-being and sense of personal accomplishment are significantly lower, and depersonalization significantly higher, when the educational purpose is psychosocial learning as opposed to academic learning. We also found some differences in conceptions of teaching among different countries and among different educational levels. These results …

Enhancing Identification Of Meteorological And Biological Targets Using The Depolarization Ratio For Weather Radar: A Case Study Of Faw Outbreak In Rwanda, Fidele Maniraguha, Anthony Vodacek, Kwang Soo Kim, Emmanuel Ndashimye, Gerard Rushingabigwi

All Rsif Scholars' Publications

Leveraging weather radar technology for environmental monitoring, particularly the detection of biometeors like birds, bats, and insects, presents a significant challenge due to the dynamic nature of their behavior. Unlike hydrometeor targets, biometeor targets exhibit arbitrary changes in direction and position, which significantly alter radar wave polarization upon scattering. This study addresses this challenge by introducing a novel methodology utilizing Rwanda’s C-Band Polarization Radar. Our approach exploits the capabilities of dual-polarization radar by analyzing parameters such as differential reflectivity (ZDR) and correlation coefficient (RHOHV) to derive the Depolarization Ratio (DR). While existing radar metrics offer valuable insights, they have limitations …
