Understanding the Effects of Personalization Behavior on Content Aggregator Use and User Satisfaction
Content aggregators have become pillars of the digital media space and provide new avenues through which entertainment content can be distributed. This research examines the role aggregation plays in directing Millennial and Gen-Z audiences to entertainment content through the lens of Media System Dependency Theory (MSDT): which content aggregators are most common within this demographic, how important the ability to personalize a content aggregator is to the user, how common personalization is within each group, and whether users feel satisfied by the content aggregators they use. This study finds that student users are widely satisfied with content aggregators, and that dependence on aggregators and personalization of content are related as anticipated by MSDT, despite only moderate aggregator use among students. Using two combined indices, positive relationships are found between user satisfaction and session frequency, dependence, and personalization. Additionally, some students are identified as power users, or individuals who spend more time personalizing and using the services than others who prefer only limited personalization
SOCIAL EXCHANGE BETWEEN DESTINATION MARKETING ORGANIZATIONS AND STAKEHOLDERS IN TENNESSEE’S RURAL COUNTIES
Promoting local culture and heritage, natural resources, farm-to-table opportunities, and outdoor recreation, more visitors are now travelling to rural communities for these experiences.
The goal for rural areas interested in tourism is to create viable and sustainable tourism through destination-marketing strategies. These strategies require extensive research, appropriate planning, and allocated funding, often managed by a Destination Marketing Organization (DMO). With the creation of the Tennessee Rural Development Task Force, Tennessee’s strategy is to increase economic growth in rural communities.
While there is a need for the DMO to form an alliance with industry stakeholders, lack of incentives and strained relationships can inhibit beneficial collaboration. This study examines the stakeholders’ perceptions of trust in the DMO by exploring the social exchanges DMOs in Tennessee rural areas currently utilize to form alliances while examining the effects on the tourism area. To achieve a deeper understanding of the social exchanges and trust involved in the relationships between DMOs and their industry stakeholders, grounded theory was chosen to explore the social interactions and study the relationships. Through interviews, participants were able to share their unique experiences and points of view to identify patterns and key themes of the social exchanges.
This study identifies the grounded theory of commitment to change stands between the realization of the need to expand social benefits for the community and identifying the appropriate strategies needed to support the development of rural tourism. When DMOs and stakeholders decide to expand benefits, they engage in social exchanges in which the DMO is perceived as trustworthy; dependable and reliable. When stakeholders commit to change, trust in the DMO and the vision rural tourism development intensifies. This results in an inclusive community identity that encompasses a brand image, a community self, and a sense of belongingness, for locals and non-locals alike. Committing to change depicts the social processes between DMOs and their stakeholders in rural Tennessee tourism areas. The social process provisions allow for the theory to be utilized to guide DMOs in formulating strategies that strengthen the alliances and build trust for successful rural development
Regulating atomic imbalance in double-well lattices
An insulating optical lattice with double-well sites is considered. In the
case of the unity filling factor, an effective Hamiltonian in the pseudospin
representation is derived. A method is suggested for manipulating the
properties of the system by varying the shape of the double-well potential. In
particular, it is shown that the atomic imbalance can be varied at will and a
kind of the Morse-alphabet sequences can be created.Comment: Latex file, 12 pages, 3 figure
A lattice of double wells for manipulating pairs of cold atoms
We describe the design and implementation of a 2D optical lattice of double
wells suitable for isolating and manipulating an array of individual pairs of
atoms in an optical lattice. Atoms in the square lattice can be placed in a
double well with any of their four nearest neighbors. The properties of the
double well (the barrier height and relative energy offset of the paired sites)
can be dynamically controlled. The topology of the lattice is phase stable
against phase noise imparted by vibrational noise on mirrors. We demonstrate
the dynamic control of the lattice by showing the coherent splitting of atoms
from single wells into double wells and observing the resulting double-slit
atom diffraction pattern. This lattice can be used to test controlled neutral
atom motion among lattice sites and should allow for testing controlled
two-qubit gates.Comment: 9 pages, 11 figures Accepted for publication in Physical Review
Non-destructive spatial heterodyne imaging of cold atoms
We demonstrate a new method for non-destructive imaging of laser-cooled
atoms. This spatial heterodyne technique forms a phase image by interfering a
strong carrier laser beam with a weak probe beam that passes through the cold
atom cloud. The figure of merit equals or exceeds that of phase-contrast
imaging, and the technique can be used over a wider range of spatial scales. We
show images of a dark spot MOT taken with imaging fluences as low as 61 pJ/cm^2
at a detuning of 11 linewidths, resulting in 0.0004 photons scattered per atom.Comment: text+3 figures, submitted to Optics Letter
High Density Mesoscopic Atom Clouds in a Holographic Atom Trap
We demonstrate the production of micron-sized high density atom clouds of
interest for meso- scopic quantum information processing. We evaporate atoms
from 60 microK, 3x10^14 atoms/cm^3 samples contained in a highly anisotropic
optical lattice formed by interfering di racted beams from a holographic phase
plate. After evaporating to 1 microK by lowering the con ning potential, in
less than a second the atom density reduces to 8x10^13 cm^- 3 at a phase space
density approaching unity. Adiabatic recompression of the atoms then increases
the density to levels in excess of 1x10^15 cm^-3. The resulting clouds are
typically 8 microns in the longest dimension. Such samples are small enough to
enable mesoscopic quantum manipulation using Rydberg blockade and have the high
densities required to investigate new collision phenomena.Comment: 4 pages, 4 figures, submitted to PR
PERANCANGAN DAN PEMBUATAN PEMEGANG BENDA KERJA OTOMATIS BERKONTUR LUAR LINGKARAN
Proses pemesinan dengan menggunakan mesin perkakas sampai saat ini
masih tetap merupakan proses yang paling banyak digunakan (60% sampai dengan
80%) untuk membuat komponen-komponen mesin yang komplit. Dalam hal ini
mesin-mesin tersebut memiliki keterbatasan dalam penggunaannya, yaitu pada
bentuk benda kerja yang dapat dikerjakan dan juga waktu pengerjaannya. Mesinmesin
ini memerlukan alat bantu yang akurat dan presisi untuk memegang benda
kerja.
Alat bantu pegang berfungsi untuk memastikan agar benda kerja yang akan
diproses tetap aman selama proses produksi berlangsung. Alat bantu pegang
mempermudah proses penempatan benda kerja sehingga beberapa benda kerja
dapat ditempatkan pada posisi yang sama. Bentuk perkakas bantu pegang
disesuaikan dengan bentuk benda kerja dan mesin yang digunakan untuk proses
produksi.
Di laboratorium Otomasi Robotika terdapat satu mesin perkakas yang tidak
memiliki alat bantu pegang. Berdasarkan tinjauan tersebut, timbul gagasan untuk
merancang dan membuat pemegang benda kerja otomatis. Pemegang benda kerja
tersebut digunakan untuk memegang benda kerja berkontur luar lingkaran.
Penggunaan pemegang benda kerja ini bertujuan untuk mempersingkat waktu
pemosisian benda kerja. Selain mempersingkat waktu pemosisian, alat bantu ini
juga dapat meningkatkan ketelitian proses pemesinan
Polyatomic Molecules Formed with a Rydberg Atom in an Ultracold Environment
We investigate properties of ultralong-range polyatomic molecules formed with
a Rb Rydberg atom and several ground-state atoms whose distance from the
Rydberg atom is of the order of n^2a_0, where n is the principle quantum number
of the Rydberg electron. In particular, we put emphasis on the splitting of the
energy levels, and elucidate the nature of the splitting via the construction
of symmetry-adapted orbitals.Comment: 2 columns, 7 pages, 7 figures. Final verso
