Jesuit Higher Education: A Journal

Abstract

This article discusses a two-year IRB-approved programmatic case study that measured the outcomes of merging a living-learning program (LLP) with service-learning. The study compared student survey data from four different pedagogical models, one of which was the hybrid LLP-service-learning model where service-learning students also participated in the LLP. We also interviewed instructors who used the LLP with their service-learning pedagogy. We used a one-way ANOVA and a non-parametric test to code and analyze the survey data. We used grounded theory to code and analyze interview data. Survey data revealed that the LLP-service-learning hybrid model scored the lowest of the …

Liberal Studies And Servant Leadership: Inspiring Ignatian Values At The Margins, Isabella Rega, Melodie Honen-Delmar

Jesuit Higher Education: A Journal

This paper aims to unpack how the concept of servant leadership is perceived from Liberal Studies graduates living at the margins of society. Anchoring this research in the work of Jesuit Worldwide Learning (JWL), a faith-based organization providing higher education to displaced and poor communities, this paper seeks to deconstruct the assumption present in the literature of an ‘already-in-power’ servant leader by inviting looking for servant leaders in vulnerable and marginalized places, where they would be most needed. By synthesizing the voices of more than 100 graduates from the Diploma in Liberal Studies program, this research looks at how graduates …


Cura Personalis: The Incarnational Heart Of Jesuit Education, Catherine Peters Jun 2022

Cura Personalis: The Incarnational Heart Of Jesuit Education, Catherine Peters

Jesuit Higher Education: A Journal

Cura personalis is one of the distinctive characteristics of Jesuit education, but the precise meaning of this phrase can sometimes be difficult to discern. Often translated as “care or education of the whole person,” the expansiveness of its formulations can lead to an overlooking of what should be central: the care of a person in their full personhood and a reminder of the person’s ultimate end. To understand cura personalis in a way that retains its distinctive character, I propose a return to Ignatius of Loyola himself, focusing especially on the importance of the Incarnation. I maintain that the …


Reimagining The Humanistic Tradition: Using Isocratic Philosophy, Ignatian Pedagogy, And Civic Engagement To Journey With Youth And Walk With The Excluded, Allen Brizee Jun 2022

Reimagining The Humanistic Tradition: Using Isocratic Philosophy, Ignatian Pedagogy, And Civic Engagement To Journey With Youth And Walk With The Excluded, Allen Brizee

Jesuit Higher Education: A Journal

The world is in a perilous place. Challenged by zealots, autocrats, a pandemic, and now a war in Europe, elected officials and their constituents no longer exchange ideas in a functioning public sphere, once a hallmark of the humanistic tradition. The timeliness of the Universal Apostolic Preferences (UAPs), therefore, is profound as they provide beacons of light for dark times. In this article, I trace Isocratic philosophy through Ignatian pedagogy and contemporary civic engagement to argue that we can use these three models to help us Journey with Youth and Walk with the Excluded. Key to this approach is a …

Standing Out While Fitting In: Exploring The Differential Roles Of Belonging And Distinctiveness In Team Choice, Tommy Derossett, Daniel L. Wann

Findings in Sport, Hospitality, Entertainment, and Event Management

Belonging and distinctiveness are considered innate motivators for human behavior and decision making. Satisfaction of both needs is often associated with increased levels of well-being and personal agency. Both belonging and distinctiveness have been examined as successful motivators for sport fandom, but research is needed to determine the differential roles of either trait in choosing a specific team or sport to follow. The current study asked participants to report their needs for belonging and distinctiveness and to choose a fictional sport team to cheer for upon moving to a new country. One team was described as being the “mainstream” team …


“A Greater [Music]” And “A Song Of Greater Power”: Lúthien's Song And Dance In The Light Of The Ainulindalë, Giovanni Carmine Costabile Jun 2022

“A Greater [Music]” And “A Song Of Greater Power”: Lúthien's Song And Dance In The Light Of The Ainulindalë, Giovanni Carmine Costabile

Journal of Tolkien Research

It is often given for granted that the whole history of Arda somehow reflects the primordial symphony played by the angelic Ainur before the highest deity Ilúvatar before the beginning of days. Yet, the specific modalities of such mirroring did not, up to the present day, receive the attention they should. Therefore, the present writing endeavours to trace the correspondances between the divine music and the narrative dedicated to the amazing accomplishments of the bethrothed Elven maiden Lúthien and human hero Beren. The choice of the latter story among all the tales of Arda is due to the fact that …

The Study Of Distribution Of Ingested Terbinafine On Skin With Ambient Ionization Tandem Mass Spectrometry, Yi-Tzu Cho, Hung Su, Ching-Ying Wu, Jingyueh Jeng, Chi-Wei Lee, Deng‐Chyang Wu, Tiao-Lai Huang, Jentaie Shiea

Journal of Food and Drug Analysis

We aim to develop an efficient and non-invasive strategy for monitoring of drugs and their metabolites via human skin. Probe sampling was combined with thermal desorption-electrospray ionization tandem mass spectrometry (TD-ESI/MS/MS) to characterize trace terbinafine, which was secreted on patient’s skin after ingesting terbinafine tablets. The terbinafine ion signals were directly detected in the samples collected from different skin regions and the signals were monitored for 8 weeks. The detection and location of terbinafine via the skin suggest that the methods are useful in rapidly and noninvasively collecting the molecular information of the ingested drug on skin for pharmacokinetic studies.

Journal of Food and Drug Analysis

Tetracycline was reported to trigger intense lucigenin chemiluminescence (CL). Based on its significant quenching to lucigenin-tetracycline CL, procyanidin was detected. The mechanism of the lucigenin-tetracycline CL and its quenching by procyanidin were proposed. Under the optimum conditions, the calibration curve is linear in the range of 10-1000 nM for procyanidin with a detection limit of 4.4 nM. The RSD for nine replicate determinations of procyanidin was less than 1.7%. Moreover, this method was satisfactorily applied to the determination of procyanidin in human urine samples and health food capsule of grape seed.

Quantitation Of Mycophenolic Acid And Metabolites By Uplc-Ms/Ms In Renal Transplant Patients, Yun-Fen Huang, Ya-Ching Huang, Hsiao-Chen Ning, Chia-Ni Lin

Journal of Food and Drug Analysis

Mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), specific inhibitors of lymphocyte proliferation, are commonly used as adjuvant therapy with calcineurin inhibitor agents after kidney transplantation. After administration, MMF and EC-MPS are hydrolyzed to mycophenolic acid (MPA), the active form of the drug, which must be monitored due to its narrow therapeutic window, drug–drug interactions, and large intra-and inter-individual pharmacokinetic variability despite a fixed dose. Monitoring plasma MPA level is recommended to maintain the drug within the therapeutic window, optimize its efficacy, and minimize side effects. This study aims to develop a method for quantifying MPA and its major metabolites …

Camphorataimide B Suppresses The Metastasis Of Human Colorectal Cancer Cell By Inhibiting Smad/Fak/Akt Axis And Promoting Degradation Of Snail/Bmp4 Complex, Chi-Chou Huang, Chia-Hung Hung, Yi-Ju Lee, Tsui-Hwa Tseng, Yean-Jang Lee, Shao-Hsuan Kao, Chau-Jong Wang

Journal of Food and Drug Analysis

Camphorataimide B (CamB) has anticancer activities against several tumors. Here, we aimed to investigate the mechanism(s) by which CamB inhibits metastasis of colorectal cancer (CRC) cells. Low-dose CamB did not affect the cell viability and cell cycle progression of CRC cells, but significantly inhibited the metastatic potentials of CRC cells. Mechanically, CamB reduced the protein and mRNA expression of BMP4, and inhibited Smad and FAK/Src/Akt signaling. CamB also decreased Snail levels by promoting its degradation via proteasome and thereafter reduced Snail-mediated BMP4 transcription. Moreover, CamB considerably inhibited the in vivo metastasis of DLD-1 cells in xenograft mice.
