Utilizing Data on Academic Dishonesty at the University of New Mexico
Academic integrity (AI) and academic dishonesty (AD) have been intensified areas of concern in higher education. This research study explored issues of students AD at the University of New Mexico (UNM). With the rise in academic dishonesty, this study was conducted with the intention of determining how AD can be deterred or discouraged. Students were asked questions regarding their previous cheating behavior, their future cheating behavior, and the reasons why they did or will cheat. The demographics of academic major (business, education, engineering, and social science), gender (male and female), or race (White and Hispanic) were studied to determine if they affect their AD. In addition, UNM, was compared to other Carnegie Very High and High Research (CHR) institutions and Hispanic Serving Institutions (HSI) to explore if these unique categories make a difference in the responses for the research questions. Based on the results of the study, recommendations were made for interventions to deter academic dishonesty. A model of Students\u27 Academic Experience (SAE) and Academic Dishonesty (AD) with Interventions (labeled the KAE model or \u27K Model\u27) is shown
The Effects Of The Vocabulary Scenario Technique- English Learner Peer Protocol on Ninth Grade English Learners Who Struggle with Literacy
Recent data have shown that only 34% of eighth graders and 37% of 12th graders were reading at or above proficiency (NAEP, 2015). A total of 21% of Hispanic eighth graders were reading at or above proficiency, and only 25% of Hispanic 12th graders were reading at or above proficiency. Of African-American students, 16% of eighth graders and 17% of 12th graders were reading at or above proficiency. In order for adolescents to become successful and productive adults, they need to acquire advanced literacy skills. Many of these demands require an education beyond high school (Rothman, 2012). Concern for English learners (EL) is even more warranted due to the fact that they represent the fastest growing school-age population in the United States and tend to exhibit lower academic achievement than their non-EL peers (Matthews & Ewen, 2006; National Clearinghouse for English Language Acquisition [NCELA], 2006; Padolsky, 2005; Thomas & Collier, 2001; Klingner, Artiles, & Barletta, 2006). To address this issue, the present study was conducted to examine the effects of a Vocabulary Scenario Technique English Learner Peer Protocol (VST-ELP) with ninth-grade English learners (ELs) who were struggling with literacy. The technique\u27s purpose was to increase students\u27 vocabulary in order to improve their listening, speaking, reading, and writing skills. The study employed an experimental design, specifically a pre-test/post-test comparison group design with a total of 34 participating students and one classroom teacher. The study was conducted over four weeks with six hours of intervention. An analysis of variance revealed that there was an increase in mean scores from pre to post in the experimental group on both the synonym and sentence tests. Findings suggest that the Vocabulary Scenario Technique English Learner Peer Protocol (VST-ELP) was effective with ninth-grade EL students who were struggling with literacy. Clinical implications and future research directions were discussed
Building career pathways in the allied health industry: a practical framework
Understanding and application of work skill requirements and the pathways to develop those skills from novice to advanced practitioner are fundamental to success in any given health profession. The research reported in this paper aims to guide the progression of allied health professionals in achieving this objective. Currently work placements in allied health disciplines provide an introduction to integrating clinical skills in the workplace; however they do not necessarily consider adaptability and sensitivity to the workplace environment or an awareness of fundamental employability skills required for career progression. In addition, current workplace assessment in the allied health industry is confined to professional appraisal/development more so than supporting the individual's capacity to progress their career. The Allied Health Career Development framework [AHCD] developed through this research is a practical tool to guide, monitor and foster progress of the individual from novice to advanced practitioner via the delineated levels of autonomy embedded within it. These levels of autonomy are ascribed to six workplace skill attributes - initiative & goal orientation; technology & resource use; learning & reflecting; planning & leadership; problem solving & critical thinking; and, communication & professionalism. The AHCD outlines the attributes required in each of these facets to progress from novice to advanced practitioner. The value of the research lies firstly, in monitoring professional growth; secondly, in the use of reflective practice and peer/mentor coaching, and thirdly, in creating a more confident, satisfied and goal orientated employee in the allied health workforce
Frankenstein\u27s Monster: The Modern Leviathan
A political close-reading of Mary Shelley\u27s Frankenstein as viewed in light of Thomas Hobbes\u27 political and moral theory as he presented it in Leviathan. This thesis argues that Hobbesian contract theory has been neglected as an effective lens for political interpretations of gothic literature in general, and shows explicitly how Hobbesian thought features in Frankenstein. Hobbes\u27 significance to arguments surrounding the French Revolution and human conflict in general is explored with a focus on the political theories of Edmund Burke, Thomas Paine, Mary Wollstonecraft and William Godwin, followed by an examination of the political significance of settings in Frankenstein. The study proceeds with an in-depth look at Hobbes\u27 contributions to the political theory of Shelley\u27s closest influences, and concludes with a Hobbesian reading of Frankenstein according to Leviathan
Geochemistry and petrogenesis of the McElroy and Larder Lake assemblages, Abitibi Greenstone Belt, Northeastern Ontario
The McElroy and Larder Lake assemblages, located in the southern Abitibi Greenstone
Belt are two late Archean metavolcanic sequences having markedly contrasting physical
characteristics arid are separated from one another by a regional fault. An assemblage is an
informal term which describes stratified volcanic and/or sedimentary rock units built during
a specific time period in a similar depositional or volcanic setting and are commonly bounded
by faults, unconformities or intrusions. The petrology and petrogenesis of these assemblages
have been investigated to determine if a genetic link exists between the two adjacent
assemblages.
The McElroy assemblage is homoclinal sequence of evolved massive and pillowed
fl.ows, which except for the basal unit represents a progressively fractionated volcanic pile.
From the base to the top of the assemblage the lithologies include Fe-tholeiitic, dendritic
flows; komatiite basaltic, ultramafic flows; Mg-tholeiitic, leucogabbro; Mg-tholeiitic, massive
flows and Fe-tholeiitic, pillowed flows. Massive flows range from coarse grained to aphanitic
and are commonly plagioclase glomerophyric. The Larder Lake assemblage consists of
komatiitic, Mg-rich and Fe-rich tholeiitic basalts, structurally disrupted by folds and faults.
Tholeiitic rocks in the Larder Lake assemblage range from aphanitic to coarse grained
massive and pillowed flows. Komatiitic flows contain both spinifex and massive textures.
Geochemical variability within both assemblages is attributed to different petrogenetic
histories. The lithologies of the McElroy assemblage were derived by partial melting of a
primitive mantle source followed by various degrees of crystal fractionation. Partial melting
of a primitive mantle source generated the ultramafic flows and possibly other flows in the
assemblage. Fractionation of ultramafic flows may have also produced the more evolved
McElroy lithologies. The highly evolved, basal, dendritic flow may represent the upper unit
3
of a missing volcanic pile in which continued magmatism generated the remaining McElroy
lithologies. Alternatively, the dendritic flows may represent a primary lava derived from a
low degree (10-15%) partial melt of a primitive mantle source which was followed by
continued partial melting to generate the ultramafic flows. The Larder Lake lithologies were
derived by partial melting of a komatiitic source followed by gabbroic fractionation.
The tectonic environment for both assemblages is interpreted to be an oceanic arc
setting. The McElroy assemblage lavas were generated in a mature back arc setting whereas
the Larder Lake lithologies were produced during the early stages of komatiitc crust
subduction. This setting is consistent with previous models involving plate tectonic processes
for the generation of other metavolcanic assemblages in the Abitibi Greenstone Belt
Cardiac Baroreflex Variability and Resetting during Sustained Mild Effort
This exploratory study assessed the pattern of closed-loop baroreflex resetting using multi-logistic-curve analysis. Operating point gain and ranges of RR-interval (RRI) and systolic blood pressure (SBP) are derived to examine how these relate to sympathetic activation. Sustained low-intensity isometric handgrip exercise, with a period of post-exercise circulatory occlusion (PECO), provided a model to study baroreflex resetting because the progression toward fatigue at constant tension induces a continuous increase in volitional contribution to neuro-cardiovascular control. Continuous measurements of muscle sympathetic nerve activity (MSNA), blood pressure, and RRI were made simultaneously throughout the experimental session. Spontaneous sequence analysis was used to detect episodes of baroreflex “engagements”, but the results are examined with a view to the fundamental difference between experimental conditions that isolate the carotid sinus (open-loop) and intact physiological conditions (closed-loop). While baroreflex function under open-loop conditions can be described in terms of a single logistic curve, intact physiologic conditions require a family of logistic curves. The results suggest that the baroreflex is in a “floating” state whereby it is continuously resetting during the timeline of the experiment but with minute-by-minute average values that mimic the less complex step-wise resetting pattern reported under open-loop conditions. Furthermore, the results indicate that baroreflex function and resetting of the operating point gain is reflected not in terms of change in the values of blood pressure or RR-interval but in terms of change in the range of values of these variables prevailing under different experimental condition
Influence of Sex and Age on Muscle Sympathetic Nerve Activity of Healthy Normotensive Adults
As with blood pressure, age-related changes in muscle sympathetic nerve activity (MSNA) may differ nonlinearly between sexes. Data acquired from 398 male (age: 39±17; range: 18-78 years [mean±SD]) and 260 female (age: 37±18; range: 18-81 years) normotensive healthy nonmedicated volunteers were analyzed using linear regression models with resting MSNA burst frequency as the outcome and the predictors sex, age, MSNA, blood pressure, and body mass index modelled with natural cubic splines. Age and body mass index contributed 41% and 11%, respectively, of MSNA variance in females and 23% and 1% in males. Overall, changes in MSNA with age were sigmoidal. At age 20, mean MSNA of males and females were similar, then diverged significantly, reaching in women a nadir at age 30. After 30, MSNA increased nonlinearly in both sexes. Both MSNA discharge and blood pressure were lower in females until age 50 (17±9 versus 25±10 bursts·min-1; P\u3c1×10-19; 106±11/66±8 versus 116±7/68±9 mm Hg; P\u3c0.01) but converged thereafter (38±11 versus 35±12 bursts·min-1; P=0.17; 119±15/71±13 versus 120±13/72±9 mm Hg; P\u3e0.56). Compared with age 30, MSNA burst frequency at age 70 was 57% higher in males but 3-fold greater in females; corresponding increases in systolic blood pressure were 1 (95% CI, -4 to 5) and 12 (95% CI, 6-16) mm Hg. Except for concordance in females beyond age 40, there was no systematic change with age in any resting MSNA-blood pressure relationship. In normotensive adults, MSNA increases after age 30, with ascendance steeper in women
Effect of parasympathetic stimulation on brain activity during appraisal of fearful expressions
Autonomic nervous system activity is an important component of human emotion. Mental processes influence bodily physiology, which in turn feeds back to influence thoughts and feelings. Afferent cardiovascular signals from arterial baroreceptors in the carotid sinuses are processed within the brain and contribute to this two-way communication with the body. These carotid baroreceptors can be stimulated non-invasively by externally applying focal negative pressure bilaterally to the neck. In an experiment combining functional neuroimaging (fMRI) with carotid stimulation in healthy participants, we tested the hypothesis that manipulating afferent cardiovascular signals alters the central processing of emotional information (fearful and neutral facial expressions). Carotid stimulation, compared with sham stimulation, broadly attenuated activity across cortical and brainstem regions. Modulation of emotional processing was apparent as a significant expression-by-stimulation interaction within left amygdala, where responses during appraisal of fearful faces were selectively reduced by carotid stimulation. Moreover, activity reductions within insula, amygdala, and hippocampus correlated with the degree of stimulation-evoked change in the explicit emotional ratings of fearful faces. Across participants, individual differences in autonomic state (heart rate variability, a proxy measure of autonomic balance toward parasympathetic activity) predicted the extent to which carotid stimulation influenced neural (amygdala) responses during appraisal and subjective rating of fearful faces. Together our results provide mechanistic insight into the visceral component of emotion by identifying the neural substrates mediating cardiovascular influences on the processing of fear signals, potentially implicating central baroreflex mechanisms for anxiolytic treatment targets
Moderate intensity intermittent lifestyle physical activity is associated with better executive function in older adults
Executive functions are among the first cognitive abilities to decline with age and age-related executive function slowing predisposes older adults to cognitive disorders and disease. Intermittent Lifestyle Physical Activity (ILPA) reflects brief, unplanned activity that occurs during routine daily activities and is operationalized as activity bouts <60s. Our understanding of short bouts of habitual physical activity and executive functions is limited. We tested the hypothesis that greater amounts of ILPA in moderate and vigorous intensity domains would be associated with better executive function in older adults. Forty older adults (26 females, 68 ± 6, >55 years; body mass index: 26.6 ± 4.3 kg/m2) completed a Trail-Making-Task and wore an activPAL 24-hr/day for 6.2 ± 1.8-days. For each intensity, total time and time spent in bouts <60 s were determined. Trail A (processing speed) and Trail B (cognitive flexibility) were completed in 25.8 ± 8.2 s and 63.2 ± 26.2 s, respectively. Non-parametric Spearman's rank correlations report that moderate ILPA (3.2 ± 3.2 min/day) and total-moderate physical activity (20.1 ± 16.0 min/day) were associated with faster Trail A (total-moderate physical activity: ρ=−0.48; moderate-ILPA: ρ = −0.50; both, p < 0.003) and Trail B time (total-moderate physical activity: ρ = 0.36; moderate-ILPA: ρ = −0.46; both, p < 0.020). However, the results show no evidence of an association with either vigorous physical activity or light physical activity (total time or ILPA bouts: all, p > 0.180). Moderate physical activity accumulated in longer bouts (>60 s) was not associated with Trail B time (p = 0.201). Therefore, more total moderate physical activity and shorter bouts (<60 s) may result in better executive functions in older adults
