Overcoming the Myth of the Contemporary âStarving Artistâ: An Exploration into the Fusion and Viability of a 21st-Century Career in Art and Design
This research explores the myth of the âstarving artistâ surrounding the pursuit of a career in the arts. Artists are often dubbed as starving due to the pre-conceived notion that careers in art do not provide longevity or financial stability. Due to this stigma, budding creatives are often dissuaded at home, school, or both from pursuing a career doing what they love. Arts programs are often cut and or remain underfunded, mainly due to this biased perception. Research indicates that careers in the arts have expanded exponentially due to its merge with various fields. According to both the STEM vs. STEAM Infographic archived in the National Arts Administration and Policy Publications Database and an article entitled, âSTEM or STEAM. Weâre missing the pointâ written by Vince Bertram, President and CEO of Project Lead The Way Inc., early arts education contributes to a more well-rounded and capable professional in several industries. It also shows that artists and designers in traditional and contemporary positions earn livable wages in stable careers. This study aims to produce a website featuring up to date information and inspiration for the aspiring creative. Coordinating materials and collateral will also be produced to help grow the siteâs visibility and further disseminate this information to students, educators, and parents
Biot-Savart-like law in electrostatics
The Biot-Savart law is a well-known and powerful theoretical tool used to
calculate magnetic fields due to currents in magnetostatics. We extend the
range of applicability and the formal structure of the Biot-Savart law to
electrostatics by deriving a Biot-Savart-like law suitable for calculating
electric fields. We show that, under certain circumstances, the traditional
Dirichlet problem can be mapped onto a much simpler Biot-Savart-like problem.
We find an integral expression for the electric field due to an arbitrarily
shaped, planar region kept at a fixed electric potential, in an otherwise
grounded plane. As a by-product we present a very simple formula to compute the
field produced in the plane defined by such a region. We illustrate the
usefulness of our approach by calculating the electric field produced by planar
regions of a few nontrivial shapes.Comment: 14 pages, 6 figures, RevTex, accepted for publication in the European

Design of conformal cooling for plastic injection moulding by heat transfer simulation
Published ArticleThe cooling channels of a mold for plastic injection have to be as close as possible to the part geometry in order to
ensure fast and homogeneous cooling. However, conventional methods to manufacture cooling channels (drilling) can
only produce linear holes. Selective laser melting (SLM) is an additive manufacturing technique capable to manufacture
complex cooling channels (known as conformal cooling). Nevertheless, because of the high costs of SLM the benefits
of conformal collings are still not clear. The current work investigates two designs of conformal coolings: i) parallel
circuit; ii) serial circuit. Both coolings are evaluated against to traditional cooling circuits (linear channels) by CAE
simulation to produce parts of polypropylene. The results show that if the conformal cooling is not properly designed
it cannot provide reasonable results. The deformation of the product can be reduced significantly after injection but the
cycle time reduced not more than 6%
The Challenges of Afghanistan and Iraq Veteransâ Transition from Military to Civilian Life and Approaches to Reconnection
Afghanistan and Iraq veterans experienced traumas during deployment, and disrupted connections with friends and family. In this context, it is critical to understand the nature of veteransâ transition to civilian life, the challenges navigated, and approaches to reconnection. We investigated these issues in a qualitative study, framed by homecoming theory, that comprised in-depth interviews with 24 veterans. Using an inductive thematic analysis approach, we developed three overarching themes. Military as family explored how many veterans experienced the military environment as a âfamilyâ that took care of them and provided structure. Normal is alien encompassed many veterans experiences of disconnection from people at home, lack of support from institutions, lack of structure, and loss of purpose upon return to civilian life. Searching for a new normal included strategies and supports veterans found to reconnect in the face of these challenges. A veteran who had successfully transitioned and provided support and advice as a peer navigator was frequently discussed as a key resource. A minority of respondentsâthose who were mistreated by the military system, women veterans, and veterans recovering from substance abuse problemsâwere less able to access peer support. Other reconnection strategies included becoming an ambassador to the military experience, and knowing transition challenges would ease with time. Results were consistent with and are discussed in the context of homecoming theory and social climate theory. Social support is known to be protective for veterans, but our findings add the nuance of substantial obstacles veterans face in locating and accessing support, due to disconnection and unsupportive institutions. Larger scale work is needed to better understand how to foster peer connection, build reconnection with family, and engage the broader community to understand and support veterans; interventions to support reconnection for veterans should be developed
Radial fingering in a Hele-Shaw cell: a weakly nonlinear analysis
The Saffman-Taylor viscous fingering instability occurs when a less viscous
fluid displaces a more viscous one between narrowly spaced parallel plates in a
Hele-Shaw cell. Experiments in radial flow geometry form fan-like patterns, in
which fingers of different lengths compete, spread and split. Our weakly
nonlinear analysis of the instability predicts these phenomena, which are
beyond the scope of linear stability theory. Finger competition arises through
enhanced growth of sub-harmonic perturbations, while spreading and splitting
occur through the growth of harmonic modes. Nonlinear mode-coupling enhances
the growth of these perturbations with appropriate relative phases, as we
demonstrate through a symmetry analysis of the mode coupling equations. We
contrast mode coupling in radial flow with rectangular flow geometry.Comment: 36 pages, 5 figures, Latex, added references, to appear in Physica D
