Developing a Theology of the Lord\u27s Supper
For many people today, the Lord\u27s Supper is the most important and significant act of the Sunday assembly when the church gathers to worship. Many of those who consider it significant, however, have little or no knowledge of its rich biblical and historical background, while even fewer have given thought to its theological foundation. There is a great need today for renewal in the area of corporate Christian worship and particularly in the church\u27s participation in the Lord\u27s Supper
A sputtered zirconia primer for improved thermal shock resistance of plasma sprayed ceramic turbine seals
The development of plasma-sprayed yttria stabilized zirconia (YSZ) ceramic turbine blade tip seal components is discussed. The YSZ layers are quite thick (0.040 to 0.090 in.). The service potential of seal components with such thick ceramic layers is cyclic thermal shock limited. The most usual failure mode is ceramic layer delamination at or very near the interface between the plasma sprayed YSZ layer and the NiCrAlY bondcoat. Deposition of a thin RF sputtered YSZ primer to the bondcoat prior to deposition of the thick plasma sprayed YSZ layer was found to reduce laminar cracking in cyclic thermal shock testing. The cyclic thermal shock life of one ceramic seal design was increased by a factor of 5 to 6 when the sputtered YSZ primer was incorporated. A model based on thermal response of plasma sprayed YSZ particles impinging on the bondcoat surface with and without the sputtered YSZ primer provides a basis for understanding the function of the primer
Lessons from the gulf: Female indigenous Emirati students’ persistence and success at university
Students’ persistence and success remain significant issues for universities worldwide, but Tinto (2017a; 2017b) argued that universities need to listen to perspectives of students themselves in identifying what causes them to persist and succeed. This article reports on such perspectives of Indigenous Emirati, Muslim women at one public university in the United Arab Emirates (UAE). Data collection from original doctoral research involved an initial, customised survey completed by 22 Emirati women with subsequent interviews conducted with a further 21 female students. Data for the purpose of this article were analysed using thematic analysis. Findings are presented within Tinto’s framework: goals; sense of belonging; self-efficacy; responses to curriculum; and their impact on students’ motivation. Tinto’s framework provides a valuable insight in understanding the women’s experiences, and their statements around persistence and success have important implications for understanding women’s progression in higher education in a society where male authority remains significant
Generation 1.5 learners: Removing the mask of student invisibility and recognising the learning disconnections that marred their academic journeys
Distinctive cohorts of students revealing inherent problems in managing their learning are on-going concerns in all universities. Students identified as Generation 1.5 learners are an increasing phenomenon in Australian universities yet may be “invisible” or unknown to teaching staff. They are neither fully proficient in their first language nor in English which is typically their second language (L2). Characteristically possessing well-developed basic interpersonal communicative skills, they lack the cognitive academic learning proficiencies essential for tertiary success. This article reports on doctoral research into six Generation 1.5 undergraduates navigating one academic year in one Western Australian university. Key findings include their “invisibility” and how L2 learning “disconnections” marred their studies. Learning disconnections comprise discrepancies and disjunctions driven by the participants’ immigration experiences, their academic needs, and their lack of connection with the teaching methods and the university-provided learning support services. Greater awareness of the distinctive features of these learners may improve their academic outcomes
A Tutorial on Radiation Oncology and Optimization
Designing radiotherapy treatments is a complicated and important task that affects patient care, and modern delivery systems enable a physician more flexibility than can be considered. Consequently, treatment design is increasingly automated by techniques of optimization, and many of the advances in the design process are accomplished by a collaboration among medical physicists, radiation oncologists, and experts in optimization. This tutorial is meant to aid those with a background in optimization in learning about treatment design. Besides discussing several optimization models, we include a clinical perspective so that readers understand the clinical issues that are often ignored in the optimization literature. Moreover, we discuss many new challenges so that new researchers can quickly begin to work on meaningful problems
RESEARCH PRODUCTIVITY AND SELECTED CHARACTERISTICS OF AGRICULTURAL ECONOMICS FACULTY IN THE SOUTHERN REGION: A QUARTER OF A CENTURY LATER
Productivity and characteristics of southern agricultural economics faculty was compared to other regional faculty. With few exceptions, faculty members in the Southern region are as productive as their counterparts. We also found that the majority of respondents in all regions considered themselves in the top-quartile in all areas.Teaching/Communication/Extension/Profession,
DETERMINANTS OF AGRICULTURAL ECONOMIC FACULTY SALARIES: A QUARTER OF A CENTURY LATER
Factors influencing the salaries of university agricultural economists were examined and compared to previous work. Results suggest the impact of publication output has remained relatively constant for the past 25 years, while other factors like grantsmanship have changed significantly. Additional analyses suggest significant impacts of appointment apportionment and Ph.D. programs.Teaching/Communication/Extension/Profession,
Tall Poppies : Bullying behaviours faced by Australian high performance school-age athlete
Little is known about Australian high-performance school-age athletes’ experiences as victims of the tall poppy syndrome. Tall poppies are successful individuals bullied by those who are less successful in order to “normalize them.” Nineteen current or previous national or international high-performance school-age athletes were interviewed (12 females and seven males). NVivo 10 was used to analyze interview data. Findings indicated all 12 females were bullied at school and this had a detrimental impact on their school life and well-being. No male athletes reported being bullied and their failure to mention this warrants further investigation. Parents and teachers require a greater awareness of tall poppy syndrome behaviors, and schools should promote an antibullying culture that includes resilience training for talented individuals
The Impacts of Medicaid Expansion on Rural Low-Income Adults: Lessons From the Oregon Health Insurance Experiment.
Medicaid expansions through the Affordable Care Act began in January 2014, but we have little information about what is happening in rural areas where provider access and patient resources might be more limited. In 2008, Oregon held a lottery for restricted access to its Medicaid program for uninsured low-income adults not otherwise eligible for public coverage. The Oregon Health Insurance Experiment used this opportunity to conduct the first randomized controlled study of a public insurance expansion. This analysis builds off of previous work by comparing rural and urban survey outcomes and adds qualitative interviews with 86 rural study participants for context. We examine health care access and use, personal finances, and self-reported health. While urban and rural populations have unique demographic profiles, rural populations appear to have benefited from Medicaid as much as urban. Qualitative interviews revealed the distinctive challenges still facing low-income uninsured and newly insured rural populations
Improved omit set displacement recoveries in dynamic analysis
Two related methods for improving the dependent (OMIT set) displacements after performing a Guyan reduction are presented. The theoretical bases for the methods are derived. The NASTRAN DMAP ALTERs used to implement the methods in a NASTRAN execution are described. Data are presented that verify the methods and the NASTRAN DMAP ALTERs
