Fishes of the Strawberry River System of Northcentral Arkansas
A survey of the fishes of the Strawberry River in northcentral Arkansas was made between August 1967 and November 1973. Field collections, literature records and museum specimens showed the ichthyofauna of the Strawberry River to be made up of 95 species distributed among 17 families. Two erroneous records are deleted. One subspecies, Etheostoma spectabile fragi,, is endemic to the river. Records of Notropis fumeus, Etheostotna nigrum, Etheostoma proeliare and Percina sciera represent extensions of previously known ranges within the state
Neophyte Qualitative Researcher Finding His Voice Through Qualitative Journeys
If you are looking for a book written about the qualitative research experience, you can find it in Victor Minichiello and Jeffery A. Kottler’s (2010c) edited volume Qualitative Journeys: Student and Mentor Experiences with Research. For a neophyte qualitative researcher who is finding his voice as a budding qualitative scholar, this book serves as an inspiration. This easy-to-read book gives a firsthand look at what other new, and oftentimes struggling, qualitative researchers experienced as they began their research journeys. Overall, the book builds a sense of excitement and interest in the qualitative paradigm; and, after reading it, I am energized to move forward with my own qualitative journey
Through the Eyes of Gay and Male Bisexual College Students: A Critical Visual Qualitative Study of their Experiences
Lesbian, gay, bisexual, and/or transgender (LGBT) college students have a history of suffering from discriminatory, marginalizing, and prejudicial attitudes and practices on American college and university campuses. Implementing a critical qualitative methodology, this study examined the lived experiences of 9 out gay and bisexual male college students at an urban research university located in the southeastern United States. The study focused on three research questions:
1) What is the college experience like for an individual who identifies as an out gay or male bisexual student?
2) What does safety mean to an individual who identifies as an out gay or male bisexual student?
3) How does an individual navigate staying safe as an out gay or male bisexual student?
The study found:
1) The presence of LGTB’ness is integral to the LGBT student experience.
2) Being involved and feeling connected to campus serves as a pivotal component of the LGBT student experience.
3) Navigating masculinity is complicated given traditional gender roles.
4) Classroom climate is a major factor for the success and safety of LGBT students.
Reviewing the results of this study college faculty, staff, and administrators can begin to understand the unique experiences of LGBT college students; and through this meaning making process, higher education officials can learn what is needed to improve the college experience for this historically marginalized minority. This study informed what colleges and universities can do to better meet the needs of LGBT college students and ensure they have a welcoming and safe college environment
Status Survey of the Arkansas Endemic Crayfish, Fallicambarus gilpini Hobbs and Robinson
Fieldwork was conducted during 2002-2003 on the rare, Arkansas endemic crayfish, Fallicambarus gilpini Hobbs and Robison. Collections at 87 localities revealed this crayfish at 8 sites, all located in southeastern Arkansas in Jefferson and Cleveland counties which significantly expands its known range. Fallicambarus gilpini was generally found inhabiting roadside ditches and areas of standing water where it was always taken from upslope areas away from the static water. A sex ratio of 1:1.3 males to females was determined for this species. Ovigerous females were collected from burrows on 20 March 2003. A conservation status of threatened is recommended for this crayfish species
Jump-Starting the Internet Revolution: How Structural Conduciveness and Global Connections Help Diffuse the Internet
The growing perception that the Internet is becoming an engine of global economic and social change has inspired both governments and intergovernmental agencies to accelerate the diffusion of the Internet around the globe via multimillion dollar programs and initiatives. Unfortunately, few empirical studies guide these initiatives. The purpose of this research is to investigate the causes that drive Internet capacity, with special emphasis on diffusion theory. Global diffusion of IT requires some degree of structural conduciveness (similarities between developed and developing countries in economic, political, and social structures) as well as contact with developed countries. In our pooled time-series models of 58 developing nations over the 1995-2000 time period, we find that both structural conduciveness (i.e., teledensity, service economies, political openness, and global urban share) and globalization (i.e., aid share, tourist share, foreign investment share, and trade share) shape the distribution and growth of Internet usage
The Fishes of Crooked Creek (White River Drainage) in Northcentral Arkansas, with New Records and a List of Species
A survey of the fishes of Crooked Creek, White River Drainage, in northcentral Arkansas was conducted using personal collections, historical records, literature records, and the Arkansas Fishes Database. The study revealed a total of 65 species of fishes distributed among 14 families. Earlier records of only 36 species in 10 families were documented. This study documents a total of 29 species and four families as new to the Crooked Creek stream system. In addition, no endangered or threatened species were collecte
Chemical Composition of Ground Water and the Locations of Permeable Zones in the Yucca Mountain Area, Nevada
Ten wells in the Yucca Mountain area of southern Nevada have been sampled for chemical analysis. Samples were obtained during pumping of water from the entire well bore (composite sample) and in one instance by pumping water from a single isolated interval in well UE-25b#1. Sodium is the most abundant cation and bicarbonate the most abundant anion in all water samples. Although the general chemical compositions of individual samples are similar, there are significant differences in uncorrected carbon-14 age and in inorganic and stable-isotope composition. Flow surveys of seven wells performed using iodine-131 as a tracer indicate that ground-water production is usually from one or more discrete zones of permeability
Description and Relationships of Chaetopterus pugaporcinus, an Unusual Pelagic Polychaete (Annelida, Chaetopteridae)
An extraordinary new species, Chaetopterus pugaporcinus, is described from eight specimens collected from deep mesopelagic waters off Monterey Bay, California, by remotely operated vehicles. All specimens exhibit a consistent combination of both adult and larval characteristics, leaving in question the maturity of the specimens. All specimens lack ciliated larval bands and the stout, modified chaetae (cutting spines) typically found in segment A4 of chaetopterids. If the specimens described here are larvae, they are remarkable for their size, which ranged from 10 to 21 mm total length, nearly twice the length of the largest polychaete larvae previously reported and 5 to 10 times larger than known chaetopterid larvae. Then too, their lack of segment addition prior to settlement would be atypical. If adult, they are particularly unusual in their habitat choice and body form. Morphology of the uncini and comparison to larval morphology indicated a close relationship to either Chaetopterus or Mesochaetopterus. However, the lack of cutting spines and typical adult morphology made it impossible to determine to what genus this species should be allied. Thus, we carried out the first molecular phylogenetic analysis of the Chaetopteridae in order to appropriately place and name the new species. Three partial genes were sequenced for 21 annelid species. The sequencing also provides the first molecular evidence that Chaetopterus variopedatus sensu Hartman (1959) is not a single cosmopolitan species. The question of C. pugaporcinus being a delayed larva or a genuine holopelagic chaetopterid is discussed
Time evolution and observables in constrained systems
The discussion is limited to first-class parametrized systems, where the
definition of time evolution and observables is not trivial, and to finite
dimensional systems in order that technicalities do not obscure the conceptual
framework. The existence of reasonable true, or physical, degrees of freedom is
rigorously defined and called {\em local reducibility}. A proof is given that
any locally reducible system admits a complete set of perennials. For locally
reducible systems, the most general construction of time evolution in the
Schroedinger and Heisenberg form that uses only geometry of the phase space is
described. The time shifts are not required to be 1symmetries. A relation
between perennials and observables of the Schroedinger or Heisenberg type
results: such observables can be identified with certain classes of perennials
and the structure of the classes depends on the time evolution. The time
evolution between two non-global transversal surfaces is studied. The problem
is posed and solved within the framework of the ordinary quantum mechanics. The
resulting non-unitarity is different from that known in the field theory
(Hawking effect): state norms need not be preserved so that the system can be
lost during the evolution of this kind.Comment: 31 pages, Latex fil
