Pre-Service Teachers’ Perceptions of Early Childhood Music Teaching Experiences
Authors: Valerio Wendy H. , Freeman Nancy K. 
Published: December 2022

Abstract
The purpose of this case study was to examine the reflections of pre-service early childhood and elementary education majors on their music teaching experiences that were a part of their undergraduate early childhood music methods course. The research questions guiding this investigation were: (a) How did participants perceive themselves and young children while they engaged in a series of early childhood pre-service music teaching experiences and (b) how did the participants perceive those experiences to influence teacher preparation and other life experiences? Participants were 6female undergraduates who completed a series of music teaching experiences and reflections during an early childhood music methods course. Each participant also agreed to be interviewed three semesters following the completion of the course. Three themes emerged with regard to the first research question: (a) developing confidence, (b) recognizing children’s music responses and development, and (c) adapting while teaching. Two themes emerged with regard to the second research question: (a) transferring music skills, content, and activities and connecting to community; and (b) using reflection for understanding child development and self-development. Participants gained experience at reflection-in-action, appreciated reflection on reflection, and valued repeated authentic music teaching experiences and developing reflective practices early in their academic careers.
The Perception of Music Learning among Parents and Students in Hong Kong
Authors: Ho Wai-Chung 
Published: December 2022

Abstract
Music education is not confined to the school context, nor does learning stop after school hours. The out-of school experiences ofchildren y especially those gained at home, are just as valuable. Parent involvementy in the form of listening to music, concert attendance, instrumental learning, and aspirations in music education, has significant direct as well as indirect effects on childrens attitudes towards music. 19 families, including 20 parents and their 21 children, revealed a number of complex and interconnected themes, which both aided and hindered students’ participation in, and learning about, music. The interview data show that: (a) though the parents and their children have different musical experiences, parents influence concert attendance, and offer financial support for childrens participation in music; (b) although instrumental learning is commonly found among students, parents often question the value of persistent learning; and (c) school music education is highly regarded by most parents though they do not expect their children to aspire to further development of their musical abilities in the future. By looking at examples of interactions between parents and children with respect to music participation and learning, this study challenges conventional notions of the extent to which parent involvement could have a positive effect on students’ attitudes toward music learning.
Predicting Jazz Improvisation Achievement through the Creation of a Path-Analytical Model
Authors: Ciorba Charles R. 
Published: December 2022

Abstract
The primary purpose of this study was to create a model to predict jazz improvisation achievement. The dependent variable was defined as jazz improvisation achievement and the independent variables were defined as: (a) self-assessment, (b) self efficacy, (c) motivation, (d) jazz theory knowledge, (e) academic achievement, (f) sight-reading ability, and (g) listening experience. A sample of high school students (N = 102) in grades 9 through 12 were chosen from 3 high schools in south Florida (n = 59) and 4 high schools in southeast Michigan (n = 43). The seven independent variables combined to account for 50% of the variance in jazz improvisation achievement. The path model revealed an adequate fit between theory and data (X² = 10.67, df= 11, p &lt; .471), indicating that a model to predict jazz improvisation achievement can be created and statistically tested.
Support Structures Contributing to Instrument Choice and Achievement among Texas All-State Male Flutists
Authors: Taylor Donald M. 
Published: December 2022

Abstract
The purpose of this study was to examine social support structures that may contribute to instrument choice and achievement among successful high school male flutists. Participants included 18 males who earned a flute or piccolo position in a Texas All-State Band or Orchestra between 2003 and 2007. Each flutist participated in a semi-structured telephone interview that was recorded and transcribed for further analysis. Answers were coded to identify common experiences among the participants. Results demonstrated that most boys started playing the flute in conjunction with beginning band classes. Across all individuals interviewed, reasons frequently cited for choosing the flute included instrument timbre, physical appearance of the instrument y and social influences of friends who played the flute. Seventeen participants had studied with a private teacher, and most began instruction within 2 years of playing. The majority of flutists had multiple teachers throughout their years of study and participated in summer music camps. While most interviewees’ parents were not actively engaged in music making, the majority of flutists cited them as their strongest means of support. Conversely, almost every participant reported initial teasing from classmates which dissipated when they began winning competitions. While most reported knowing few other male flutists, nearly all cited professional male flutists as their favorite recording artists, including fames Galway, Jean-Pierre Rampal, and EmmanuelPahud. Almost all participants described the All-State experience as their greatest musical achievement in high school, which helped inform their future career choices.
The Effect of Teaching Experience on Time and Accuracy of Assessing Young Singers’ Pitch Accuracy
Authors: Hedden Debra G. , Johnson Christopher 
Published: December 2022

Abstract
The purpose of this study was to investigate the effect of pre-service and practicing music teachers’ experience on time and accuracy of assessing young singers. A total of 55 participants – freshmen (n = 14) and senior (n = 17) music education students, and beginning (n = 12) and experienced (n = 12) music teachers – listened to stimuli containing in-tune and out-of-tune singing of the first nine pitches of America on a neutral syllable, assessing the pitch-matching accuracy of the singing. Participants heard twenty stimuli of second-grade singers and responded through the use of the Continuous Response Digital Interface (CRDI) device. Each stimulus was heard only once, with distraction music inserted between stimulus examples. Results indicated that freshman participants responded much more slowly to the stimuli than did the other three groups, and that all groups were much more accurate assessing out-of-tune singers than in-tune singers; though there were no overall differences in assessment accuracy between groups. Based on these data, the implications for teaching music were questioned, and though it is considered that latency and accuracy are important for successful music programs, the degree of importance they play is not completely clear.
Aesthetic Responses of Music and Non-Music Majors to Gradual Pitch Center Changes
Authors: Hancock Carl B. 
Published: December 2022

Abstract
The purpose of this study was to determine if music and non-music majors’ aesthetic responses are differentiated by gradually changing pitch center conditions. One hundred and forty-four university students listened to a professional recording of the second movement of Samuel Barbers Concerto for Violin and Orchestra, Op. 14 altered to have a gradually rising (sharper) or lowering (flatter) pitch center changing at a rate of 1/100 of a semitone (1 cent) per second. Participants recorded their aesthetic responses using a Continuous Response Digital Interface (CRDI). Results of a two-way ANOVA indicated a significant main effect for pitch condition and an interaction effect for major and pitch condition. Mean aesthetic response scores for music and non-music majors hearing the gradually flatter performance were lower than those for the unaltered condition. There was little difference in the scores of non-music majors between the gradually sharper and unaltered conditions, however, music majors’ mean scores were lower under the gradually sharper condition.
A Case Study of the Creation of a Technology-based Music Course
Authors: Dammers Richard J. 
Published: December 2022

Abstract
This study examines the process, motivations, and conditions surrounding the creation of a high school music technology class. The process was initiated by Steve, the school’s band director, who wanted to reach a broader portion of the school’s population. The process was facilitated by Diana, the district’s assistant superintendent, who believed in technology’s ability to engage students and in the importance of the arts in education. While Steve was able to address the pre-requisite concerns of scheduling and space, Diana was able to provide monetary support through external grant funding This study confirms and clarifies that technology-based music classes are being created by individual teachers, who believe that technology provides an opportunity to reach a new population of secondary students.
Missionaries to the Wilderness: A History of Land, Identity, and Moral Geography in Appalachia
Authors: Fraley Jill 
Published: December 2022

Abstract
This article revisits the relationship between missionaries and Appalachian stereotypes, bringing to the discussion new developments in geographical theory and the intellectual history of ideas of wilderness. The article argues that missionary activities during the early twentieth century are best understood through their beliefs about wilderness and particularly about the moral climate of man within it. In this way the missionaries also contributed to the process of intermingling ideas about the land and the people and thereby contributed to the formation of a quasi-ethnic regional identity in the American public consciousness—and also substantially changed Appalachia by applying a set of hierarchical land values that stemmed from ideas about wilderness.
Into the Crucible: The Chesapeake and Ohio Railroad and the Black Industrial Worker in Southern West Virginia, 1870 - 1900
Authors: Fain Cicero 
Published: December 2022

Abstract
While scholars have examined much about the black circums tance in the coalfields of southern West Virginia, little has been written about the lives and experiences of black migrants who arrived into the region to garner gainful employment as laborers on the upstart Chesapeake and Ohio Railroad. Leaving homes and families, pioneering black migrants, along with native whites and European immigrants, performed the critical backbreaking and dangerous work necessary to construct the railroad from the James River in Virginia through the tortuous New River Valley to the Ohio River. In the process, significant numbers died, many unceremoniously—victims of the twin demands of racism and wage-capitalism. Yet black labor, first on the C&O, and then in the coalmines of southern West Virginia, helped transform the region, linking it to the national and world economy. During and after construction many black migrants settled into the embryonic villages and towns that grew attendant to the railroad, including Huntington, West Virginia, founded in 1871 as a transshipment station for the C&O. Drawn by the promise of available jobs, increasing numbers of black migrants arrived into the town to perform the menial, dangerous, and routine urban-industrial jobs affiliated with the railroad. In the process, they helped link, in ways not dissimilar to the process initiated by the construction of the C&O, the town to the regional and national economy. Enduring occupational constraints and racism, but simultaneously beneficiaries of wage-capitalism, material gain, community, and family, black migrants and their labor helped transform the region and town. This article examines their experiences.
Effect of CGM Access Expansion on Uptake Among Patients on Medicaid With Diabetes
Authors: Ni Kevin , Tampe Carolyn A. , Sol Kayce , Richardson Douglas B. , Pereira Rocio I. 
Published: December 2022

OBJECTIVE
Current studies on continuous glucose monitor (CGM) uptake are revealing for significant barriers and inequities for CGM use among patients from socially underprivileged communities. This study explores the effect of full subsidies regardless of diabetes type on CGM uptake and HbA1c outcomes in a U.S. adult patient population on Medicaid.

RESEARCH DESIGN AND METHODS
This retrospective cohort study examined 3,036 adults with diabetes enrolled in a U.S. Medicaid program that fully subsidized CGM. CGM uptake and adherence were assessed by CGM prescription and dispense data, including more than one fill and adherence by medication possession ratio (MPR). Multivariate logistic regression evaluated predictors of CGM uptake. Pre- and post-CGM use HbA1c were compared.

RESULTS
CGM were very well received by both individuals with type 1 diabetes and individuals with type 2 diabetes with similar high fill adherence levels (mean MPR 0.78 vs. 0.72; P = 0.06). No significant difference in CGM uptake outcomes were noted among major racial/ethnic groups. CGM use was associated with improved HbA1c among those with type 2 diabetes (−1.2% [13.1 mmol/mol]; P &lt; 0.001) that was comparable between major racial/ethnic groups and those with higher fill adherence achieved greater HbA1c reduction (−1.4% [15.3 mmol/mol]; P &lt; 0.001) compared with those with lower adherence (−1.0% [10.9 mmol/mol]; P &lt; 0.001).

CONCLUSIONS
CGM uptake disparities can largely be overcome by eliminating CGM cost barriers. CGM use was associated with improved HbA1c across all major racial/ethnic groups, highlighting broad CGM appeal, utilization, and effectiveness across an underprivileged patient population.

Abstract

OBJECTIVE
To investigate an alternative treatment for bovine mastitis by using Pm11 antimicrobial peptide.

SAMPLE
5 bovine mastitis pathogens that were previously isolated from cows affected by either clinical or subclinical mastitis.

PROCEDURES
The current study introduces Pm11 antimicrobial peptide as an alternative treatment for bovine mastitis. The antibacterial activity of Pm11 was tested against Escherichia coli strain SCM1249, Klebsiella spp strain SCM1282, Staphylococcus aureus strain CM967, Streptococcus agalactiae strain SCM1084, and Streptococcus uberis strain SCM1310 using minimum bactericidal concentrations (MBCs) and time-kill kinetics. The pathogens’ morphological changes were demonstrated using a scanning electron microscope (SEM). The cytotoxicity of Pm11 was assessed using the minimum hemolytic concentration assay.

RESULTS
MBCs ranged from 2.5 to 10 μM and IC50 ranged from 0.32 to 2.07 μM. Time-kill kinetics at MBC demonstrated that Pm11 reduced viable cell counts of S agalactiae strain SCM1084 and S uberis strain SCM1310 from 105 to 0 CFU/mL within 1 h. E coli strain SCM1249 and S aureus strain CM967 were reduced from 105 to 0 CFU/mL within 4 h. The average Pm11-induced hemolytic activity was < 10% for all Pm11 concentrations tested except at the maximum concentration tested (160 μM: 10.19 ± 2.29%). Based on SEM, Pm11 induced morphological and cellular changes in S aureus and E coli.

CLINICAL RELEVANCE
Pm11 antimicrobial peptide demonstrated in vitro antibacterial activity against the common bovine mastitis pathogens E coli, S aureus, S agalactiae, and S uberis, except Klebsiella spp, and should be further investigated in vivo.
Work Ability and Psychosocial Factors in Healthcare Settings During COVID-19 Pandemic – Specific Focus on Ageing Workers
Authors: Kurashvili Mari , Reinhold Karin , Järvis Marina 
Published: December 2022

Abstract
The paper aims to find out what kind of impact socio-demographic and psychosocial factors have on the work ability among healthcare workers during COVID-19 pandemic – specific focus on ageing workers. Work Ability Index (WAI) and the short version of the Copenhagen Psychosocial Questionnaire (COPSOQ-III) were used to analyse the impact. 424 healthcare workers from Georgian and Estonian hospitals (including doctors and nurses) answered the questionnaires. On average, the sample had a good work ability, with 48.8 % viewing it as good and 29.3 % as excellent in Georgia, and 53.6 % of participants had a good and 15.4 % excellent work ability in Estonia. The COPSOQ showed critical values in the scales of “work pace” and “emotional demands”. These results were expected as the data were collected during the pandemic period. “Sleep troubles”, “burnout”, “depressive symptoms”, and “insecurity over working conditions” were the risk factors more likely associated with ageing (+55) health workers than younger ones. The scales “quantitative demands”, “work pace”, “job insecurity”, “burnout”, “stress”, “sleep troubles”, “offensive behaviours” and “depressive symptoms” were in negative correlation with WAI. The results show that the work ability is higher when these factors are lower. The scales “role clarity”, “recognition”, “sense of community at work”, “quality of leadership”, “organisational justice”, “self-efficacy”, “meaning of work”, “job satisfaction” and “possibilities for development” were the risk factors in positive correlation with WAI, thus acting as work ability preservative aspects.
Assessment of Urban Expansion and Identification of Sprawl Through Delineation of Urban Core Boundary

Published: December 2022

Abstract
Cities are spatially expanding rapidly, leading to urban sprawl. This study aims to understand the nature of the urban expansion of Chennai city, located on India’s southeastern coast, by determining the urban growth pattern and identifying the urban sprawl areas. The urban growth pattern and sprawl areas between 1998 and 2019 are identified using remote sensing data through the delineation of the Urban Core Boundary (UCB). The urban areas were extracted from the Land Use Land Cover (LULC) classification using combined classification technique to delineate the UCB. All the findings were validated using ground truth information. LULC classification performed with an accuracy of more than 90 % for urban land cover revealed an increase in urban cover by 71.77% from 1998 to 2009 and
36.91 % from 2009 to 2019. The delineated UCB’s peripheral distance was measured from the city centre in an anticlockwise direction from 0˚ to 360˚ at every 10˚ interval. It is observed that the urban core boundary expanded to a maximum of 16.02 km along 240˚ and
11.93 km along 220˚ from the city centre, and the lands in the vicinity of the National Highway (NH 32), which is situated between these sectors, experienced maximum urban development. The study also pinpointed the sprawl areas during the study period, revealing that the urban sprawl occurs along the highways, around designated special economic zones, and industrial corridors.
Pengaruh Pemberian Larutan Daun Pepaya Pada Lele yang Diinfeksi Aeromonas hydrophila Ditinjau dari Histopatologi Insang, Kulit, dan Otot

Published: December 2022

Histopatologi dapat memberikan gambaran perubahan atau kelainan pada level jaringan. Parameter utama pada penelitian ini adalah histopatologi insang, kulit, dan otot. Penelitian menggunakan dua kontrol yaitu kontrol normal (tanpa infeksi dan tanpa perlakuan daun pepaya) dan kontrol infeksi (tanpa paparan larutan daun pepaya). Lima perlakuan yang digunakan yaitu pengobatan dengan paparan larutan daun pepaya dengan dosis 10, 15, 20, 25 dan 30 mg/mL. Hasil penelitian menunjukkan insang dan kulit ikan normal tidak mengalami hiperplasia. Otot ikan normal terlihat kompak dan rapat antara sel yang satu dengan yang lainnya. Insang dan kulit ikan yang terinfeksi mengalami kerusakan jaringan. Kerusakan jaringan juga terjadi pada perlakuan pengobatan paparan larutan daun pepaya berupa hiperplasia dengan tingkat radang, degenarasi, dan nekrosis yang berbeda-beda. Hasil skoring ikan terinfeksi tanpa pengobatan memiliki memiliki nilai yang hampir sama dengan perlakuan pengobatan pada paparan larutan daun pepaya dosis 25 dan 30 mg/mL. Hal ini diakrenakan larutan dnegan konsentrasi tinggi memberikan efek toksik. Sebaliknya, dosis 10 mg/mL kurang efektif untuk pengobatan karena bersifat bakteriostatik yaitu hanya menahan pergerakan bukan membunuh bakteri. Dosis yang tepat untuk membunuh bakteri dan tidak bersifat toksik adalah pengobatan dengan paparan larutan daun pepaya dosis 15 dan 20 mg/mL. Hal tersebut didukung oleh kelulushidupan ikan lele.
