A reexamination of Factors Contributing to Apparel Majors\u27 Stress and Abilities to Effectively Manage their Time
This study is a replication of the time spent and stress study reported in 2006. The purpose of this study was to provide an update to the original results, noting differences and similarities among students today vs. five years ago
Directionality Effects and Exceptions in Learning Phonological Alternations
The present study explores learning vowel harmony with exceptions using the artificial language learning paradigm. Participants were exposed to a back/round vowel harmony pattern in which one affix (either prefix or suffix, depending on the condition) alternated between /me/ and /mo/ depending on the phonetic feature of the stem vowels. In Experiment 1, participants were able to learn the behaviors of both alternating and non-alternating affixes, but were more likely to generalize to novel affixes for non-alternating items than alternating items. In Experiment 2, participants were exposed to training data that contained non-alternating affixes in prefix position while alternating affixes were all suffixes, or vice versa. Participants were able to extend the non-alternating affixes to the novel direction, suggesting that participants inferred a non-directional harmony pattern. Overall, the patterns of alternating affixes are harder to learn than patterns of exceptions that do not alternate, which aligns with previous findings supporting a non-alternation bias. Our study raises the question of how biases towards exceptionality and directionality interact in phonological learning
High frequency GaAs nano-optomechanical disk resonator
Optomechanical coupling between a mechanical oscillator and light trapped in
a cavity increases when the coupling takes place in a reduced volume. Here we
demonstrate a GaAs semiconductor optomechanical disk system where both optical
and mechanical energy can be confined in a sub-micron scale interaction volume.
We observe giant optomechanical coupling rate up to 100 GHz/nm involving
picogram mass mechanical modes with frequency between 100 MHz and 1 GHz. The
mechanical modes are singled-out measuring their dispersion as a function of
disk geometry. Their Brownian motion is optically resolved with a sensitivity
of 10^(-17)m/sqrt(Hz) at room temperature and pressure, approaching the quantum
limit imprecision.Comment: 7 pages, 3 figure
An empirical study on customers’ behavior of passive and active resistance to innovation
Previous studies reveal that the failure rate of innovation in enterprises
is higher than expected. The reason for innovation failures is
due to not only the customers’ resistance towards innovation, subsequent
changes and ignored factors that promote customer
acceptance, but also the other disregarded factors that motivates
the resistance towards innovation adaptation. The literature proved
the customers’ innovation resistance (CIR) consists of two categories.
Passive innovation resistance (PIR) described as initial resistance
behavior before evaluating the new product; and active
innovation resistance (AIR) introduced as the resistant behavior
after evaluating innovative products. However, few studies have
investigated the simultaneous influence of both PIR and AIR, especially
using the empirical methods. The main purposes of this study
are (1) to construct a model that reflects on both PIR and AIR as
two categories of CIR; (2) to provide empirical evidences to highlight
the influences and correlation of PIR and AIR. The method
used in this paper is partial least squares path modeling (PLS-PM)
method to test our model and the hypotheses. The results from this
research mainly indicate that (1) PIR is negatively influenced AIR; (2)
PIR (including both cognitive and situational PIR) has negative
effect on customers’ innovation adoption intention (IAI) while (3)
the correlation between AIR and IAI is opposite; (4) the degree of
customers’ IAI with high-perceived stimulation group and low-perceived
stimulation group will reverse according to the changes of
PIR and AIR. This paper is helpful for enterprises to improve their
innovation success rate by analyzing users’ resistance to innovatio
Giant spin Hall Effect in two-dimensional monochalcogenides
One of the most exciting properties of two dimensional materials is their
sensitivity to external tuning of the electronic properties, for example via
electric field or strain. Recently discovered analogues of phosphorene,
group-IV monochalcogenides (MX with M = Ge, Sn and X = S, Se, Te), display
several interesting phenomena intimately related to the in-plane strain, such
as giant piezoelectricity and multiferroicity, which combine ferroelastic and
ferroelectric properties. Here, using calculations from first principles, we
reveal for the first time giant intrinsic spin Hall conductivities (SHC) in
these materials. In particular, we show that the SHC resonances can be easily
tuned by combination of strain and doping and, in some cases, strain can be
used to induce semiconductor to metal transitions that make a giant spin Hall
effect possible even in absence of doping. Our results indicate a new route for
the design of highly tunable spintronics devices based on two-dimensional
materials
The power of story: Narrative inquiry as a methodology in nursing research
The aim of this paper is to explore the essential elements and value of narrative inquiry in nursing research. We propose that understanding a previous experience allows the nurse researcher an insider view and hence a deeper understanding of the issues that arise in the relationship between participant and researcher. We suggest that narrative inquiry in nursing research offers a particular way of caring about how knowledge is produced. Nursing science would benefit from the understanding that health and nursing practices are dynamic processes characterized by the continuous interaction of human thought and behaviour that continuously \u27pumps\u27 into personal, social and material environments. Narrative inquiry as a methodology in nursing research is exceptionally useful to uncover nuance and detail of previous experiences
