More than Artistry: The Integral Aspect of Autobiography
Authors: Karpiak Irene 
Published: June 2016

Autobiography has generally been recognized for its literary and artistic aspects, and as a result has been largely overlooked as an instructional method in adult and continuing education. This paper argues for a wider use of autobiography in adult and continuing education programs, proposing that autobiography actually encompasses not only the artistic and literary aspects of life writing, but also the theoretical and philosophical. Based on the autobiographical writings of adult learners collected over a decade of teaching, the author suggests that in the course of bringing these dimensions of their lives together, these writers further not only their understanding of themselves and their world, but also their commitment to educational practice, action, and change.
Adult Learning and Change: An Autobiographical Portrait of a Chinese Woman in Canada
Authors: Liu Chun Ge 
Published: June 2016

The themes of adult learning, cross-cultural learning, and transformative learning are common to many continuing educators working at universities across Canada. In this essay, I narrate my experiences as a mature, adult learner returning to university. Following a literature review and discussion of methodology, I begin this autobiographical portrait with a description of my initial education and life experiences in China. From this foundation, I describe and interpret my cross-cultural sojourn as a graduate student in Canada. This sojourn was both happy and sad, both empowering and disempowering. My story is one of learning—learning as an adult, learning in a cross-cultural setting, and learning that ultimately had a transformative impact on how I view myself and my world. Through exploring my own experiences with learning and change, I hope to offer readers of the Canadian Journal of Continuing Education a unique opportunity for insight into personal processes that are difficult to truly understand at a theoretical level alone.
Perceptions of Writing Confidence, Critical Thinking, and Writing Competence among Registered Nurse-Learners Studying Online
Authors: Carter Lorraine 
Published: June 2016

Historically, nursing education has recognized that writing enhances critical thinking, the basis of the clinical reasoning process. The online learning recently adopted by Nursing involves considerable writing, which may enhance critical thinking more than face-to-face courses. In the study reported here, the critical thinking and writing experiences of 34 registered nurses in an online course at an Ontario university were considered from several perspectives: perception of writing competence; demonstration of levels and kinds of critical thinking; and demonstration of writing competence. Although the participants’ perceptions of their writing competence increased significantly, these results were not reflected in their levels of writing competence when compared to that of younger nurse-learners and students in an Arts course at the university. The study did not demonstrate that online writing results in different levels of critical thinking; it did, however, suggest a connection between and among online writing, different kinds of critical thinking, and assignment design.
Back Eddies of Learning In the Recognition of Prior Learning: A Case Study
Authors: Peruniak Geoff , Powell Rick 
Published: June 2016

The limited research that exists in the area of prior learning assessment (PLA) has tended to be descriptive and conceptual in nature. Where empirical studies have been done, they have focussed mainly on PLA as a means of credentialing rather than as a learning experience. Furthermore, there has been very little empirical research into the educational effectiveness of PLA from the student’s point of view. This empirical study used a qualitative approach to investigate the perceptions of a focus group of 32 adult learners who were engaged in portfolio-based PLA in an open and distance education university. The study explored students’ initial expectations of PLA, what they think they got out of the process, and the extent to which these perceived benefits of PLA would extend to other adult students. The study examined the question of whether PLA operates as a motivator or as a selection mechanism and concluded that there was evidence for both factors. Further results indicated that, in general, PLA learners were surprised to find they had been engaged in a learning process. The study concludes that PLA can be an effective educational opportunity for certain kinds of adult learners, but it should not be taken as a panacea.

Published: June 2016

A rotor-stator rubbing position identification method based on casing velocity signal is proposed. Considering that velocity is an ideal parameter to reflect vibration, and its effective value is a standard to the measuring of vibration fault diagnosis in the world, firstly, the rotor experiment rig of aero-engine was used to simulate rubbing faults in different rubbing positions, and casing vibration acceleration signal was collected and changed to velocity signal through integral and polynomial least square fitting method. Secondly, low-frequency normalized energy characteristics of velocity signal and normalized mean-square value characteristics of acceleration signal were extracted; finally, normalized characteristic parameters including energy and mean-square value were input to nearest neighbor classifier and support vector machine(SVM) to identify the different rubbing positions. The results show that low-frequency energy characteristics of velocity signal can effectively identify the rotor-stator rubbing positions of aero-engine, and reach to 93 % of recognition rate based on nearest neighbor classification method and 98 % based on SVM, while mean-square value characteristics of acceleration signal recognition rate can only reach 81 % based on nearest neighbor algorithm and 85 % based on SVM.

Authors: Sun Ze-gang , Xiao Shi-de , Xu Ming-heng , Wei Wei 
Published: June 2016

The cavitation flow of axial piston pump was simulated by the FLUENT software. Simulation results show that 1) Plunger cavity cavitation degree increase nearly one time when the piston pump rotation rate increase from 1500 r/min to 3000 r/min; 2) The axial piston pump L shape throttling groove is more conductive to inhibiting cavitation of plunger cavity than the V shape; 3) The variation law which shows the influence of the thickness of cylinder kidney shape port on the cavitation of plunger cavity. This paper put forward the two-way inclined type cylinder barrel kidney shape port, which was beneficial to improve the self-sucking of the plunger cavity under high speed rotation and could inhibit the cavitation of plunger cavity. The Kriging agent model of has been established by taking the configuration parameters of one-way inclined cylinder kidney shape port as independent variables and the mean value of the gas volume fraction of plunger cavity as target function, based on the Kriging interpolation principle. The optimized structure of the one-way inclined type cylinder barrel kidney shape port is obtained through the Kriging agent model which is optimized by using improved genetic algorithm. The structure of the cylinder kidney shape port and the valve plate throttling grooves are obtained, which mostly inhibit the cavitation of plunger cavity with above analysis. The structure has a strong inhibitory on the plunger cavity cavitation through the simulation analysis and verification.

Published: June 2016

AbstractUsing a low temperature hydrothermal method, zinc oxide (ZnO) nanorod arrays were grown from seed layers coated on silicon substrates. The grown morphologies of the nanorod arrays heavily depend on the seed layer preparation methods. The grown nanorod arrays are of high density and good crystallinity with <002> preferred orientation for the nanorod arrays growing from uniformly distributed nucleation sites which are prepared on the seed layers by using the solvent ethanol. Using a conductive atomic force microscope, the dependence of the output current generated from the piezoelectric effect of bending a single nanorod was characterized. The output current increases with increasing the free bending lengths and applied force due to the increase in the deformation of the ZnO nanorods, and the maximum output current is 2.6 nA. The dependence of the bending-induced output current on the growth parameters, the nanorod array morphology and inclined orientation feature is discussed.
Dynamic crushing behavior of functionally graded honeycomb structures with random defects
Authors: Fan Tao 
Published: June 2016

Abstract
In the present work, the in-plane dynamic crushing behavior of functionally graded honeycomb structures with missing-wall defects is investigated. To study the influences of the functionally graded properties on dynamic crushing, a density gradient is introduced by changing the cell wall thicknesses along the impact direction. Results show that both the deformation mode and energy absorption are sensitive to the density gradient. However, the deformation mode displays less dependence on the density gradient when the honeycomb is impacted at a high velocity. Furthermore, the effects of defect ratios and defect locations are discussed. Results reveal that the larger defect ratio is responsible for the lower energy absorption. For the case of 70 m s−1 impact velocity, defects in the middle of the structure should be avoided, as they lead to inferior energy absorption.
Dry sliding friction and wear behavior of bronze matrix composites reinforced with Ni3Al particles: Comparison with conventional brake lining
Authors: Çelikyürek İbrahim , Biçer Aytaç 
Published: June 2016

Abstract
Bronze matrix composites reinforced with Ni3Al particles were produced by means of a classical powder metallurgy (PM) technique. The Ni3Al particles used as reinforcement were produced by ball milling of cast alloy. The powders of the constituents of the bronze and Ni3Al powder were blended, compressed axially and sintered. The microstructures of the composites were characterized using optical microscopy and scanning electron microscopy. The compression strength and hardness of the composites were investigated. The tribological properties of composites and unreinforced bronze were determined using pin-on-disk geometry and results were compared with conventional phenolic resin bonded brake lining. The results showed that the PM bronze had higher strength than the composites while the hardness of the composites was higher than the PM bronze. According to dry sliding friction and wear tests, the composites have higher wear resistance and coefficient of friction than the conventional brake lining.
ON THE SOCIAL TRAITS OF LUMINOUS BLUE VARIABLES
Authors: Humphreys Roberta M. , Weis Kerstin , Davidson Kris , Gordon Michael S. 
Published: June 2016

ABSTRACT
In a recent paper, Smith & Tombleson state that the luminous blue variables (LBVs) in the Milky Way and the Magellanic Clouds are isolated; they are not spatially associated with young O-type stars. They propose a novel explanation that would overturn the standard view of LBVs. In this paper we test their hypothesis for the LBVs in M31 and M33, as well as the LMC and SMC. We show that in M31 and M33 the LBVs are associated with luminous young stars and supergiants that are appropriate to their luminosities and positions on the H-R diagram. Moreover, in the Smith and Tombleson scenario most of the LBVs should be runaway stars, but the stars’ velocities are consistent with their positions in the respective galaxies. In the Magellanic Clouds, those authors’ sample was a mixed population. We reassess their analysis, removing seven stars that have no clear relation to LBVs. When we separate the more massive classical and the less luminous LBVs, the classical LBVs have a distribution similar to the late O-type stars, while the less luminous LBVs have a distribution like the red supergiants. None of the confirmed LBVs have high velocities or are candidate runaway stars. These results support the accepted description of LBVs as evolved massive stars that have shed a lot of mass and are now close to their Eddington limit.
EPISODIC HIGH-VELOCITY OUTFLOWS FROM V899 Mon: A CONSTRAINT ON THE OUTFLOW MECHANISMS*
Authors: Ninan J. P. , Ojha D. K. , Philip N. S. 
Published: June 2016

ABSTRACT
We report the detection of large variations in the outflow wind velocity from a young eruptive star, V899 Mon, during its ongoing high accretion outburst phase. Such large variations in the outflow velocity (from −722 to −425 km s−1) have never been reported previously in this family of objects. Our continuous monitoring of this source shows that the multi-component, clumpy, and episodic high velocity outflows are stable in the timescale of a few days, and vary over the timescale of a few weeks to months. We detect significant decoupling in the instantaneous outflow strength to accretion rate. From the comparison of various possible outflow mechanisms in magnetospheric accretion of young stellar objects, we conclude magnetically driven polar winds to be the most consistent mechanism for the outflows seen in V899 Mon. The large scale fluctuations in outflow over the short period makes V899 Mon the most ideal source to constrain various magnetohydrodynamics simulations of magnetospheric accretion.
3FGL DEMOGRAPHICS OUTSIDE THE GALACTIC PLANE USING SUPERVISED MACHINE LEARNING: PULSAR AND DARK MATTER SUBHALO INTERPRETATIONS

Published: June 2016

ABSTRACT
Nearly one-third of the sources listed in the Third Fermi Large Area Telescope (LAT) catalog (3FGL) remain unassociated. It is possible that predicted and even unanticipated gamma-ray source classes are present in these data waiting to be discovered. Taking advantage of the excellent spectral capabilities achieved by the Fermi LAT, we use machine-learning classifiers (Random Forest and XGBoost) to pinpoint potentially novel source classes in the unassociated 3FGL sample outside the Galactic plane. Here we report a total of 34 high-confidence Galactic candidates at

. The currently favored standard astrophysical interpretations for these objects are pulsars or low-luminosity globular clusters hosting millisecond pulsars (MSPs). Yet these objects could also be interpreted as dark matter annihilation taking place in ultra-faint dwarf galaxies or dark matter subhalos. Unfortunately, Fermi LAT spectra are not sufficient to break degeneracies between the different scenarios. Careful visual inspection of archival optical images reveals no obvious evidence for low-luminosity globular clusters or ultra-faint dwarf galaxies inside the 95% error ellipses. If these are pulsars, this would bring the total number of MSPs at

to 106, down to an energy flux ≈4.0 × 10−12 erg cm−2 s−1 between 100 MeV and 100 GeV. We find this number to be in excellent agreement with predictions from a new population synthesis of MSPs that predicts 100–126 high-latitude 3FGL MSPs depending on the choice of high-energy emission model. If, however, these are dark matter substructures, we can place upper limits on the number of Galactic subhalos surviving today and on dark matter annihilation cross sections. These limits are beginning to approach the canonical thermal relic cross section for dark matter particle masses below ∼100 GeV in the bottom quark (

) annihilation channel.
STAR FORMATION AND AGN ACTIVITY IN GALAXY CLUSTERS FROM z = 1–2: A MULTI-WAVELENGTH ANALYSIS FEATURING HERSCHEL/PACS

ABSTRACT
We present a detailed, multi-wavelength study of star formation (SF) and active galactic nucleus (AGN) activity in 11 near-infrared (IR) selected, spectroscopically confirmed massive (≳1014
M
⊙) galaxy clusters at 1 < z < 1.75. Using new deep Herschel/PACS imaging, we characterize the optical to far-IR spectral energy distributions (SEDs) for IR-luminous cluster galaxies, finding that they can, on average, be well described by field galaxy templates. Identification and decomposition of AGNs through SED fittings allows us to include the contribution to cluster SF from AGN host galaxies. We quantify the star-forming fraction, dust-obscured SF rates (SFRs) and specific SFRs for cluster galaxies as a function of cluster-centric radius and redshift. In good agreement with previous studies, we find that SF in cluster galaxies at z ≳ 1.4 is largely consistent with field galaxies at similar epochs, indicating an era before significant quenching in the cluster cores (r < 0.5 Mpc). This is followed by a transition to lower SF activity as environmental quenching dominates by z ∼ 1. Enhanced SFRs are found in lower mass (

) cluster galaxies. We find significant variation in SF from cluster to cluster within our uniformly selected sample, indicating that caution should be taken when evaluating individual clusters. We examine AGNs in clusters from z = 0.5–2, finding an excess AGN fraction at z ≳ 1, suggesting environmental triggering of AGNs during this epoch. We argue that our results—a transition from field-like to quenched SF, enhanced SF in lower mass galaxies in the cluster cores, and excess AGNs—are consistent with a co-evolution between SF and AGNs in clusters and an increased merger rate in massive halos at high redshift.
