Recent Results from HEGRA (Gamma-Ray Observations with the HEGRA Stereoscopic System of 5 Cherenkov Telescopes)
The HEGRA collaboration has achieved outstanding results during the operation
of the six imaging atmospheric Cherenkov telescopes from 1996 to 2002. The
experimental work pioneered the field of TeV gamma-ray astronomy with
observations during partial moon time and mainly by applying the stereoscopic
observation mode using a system of five Cherenkov telescopes.
Concerning Galactic objects the HEGRA observations have led to a precise
measurement of the energy spectrum of the Crab nebula between 0.5 and 80 TeV,
the detection of the first shell type supernova remnant in the Northern
hemisphere (Cassiopeia A) and the investigation of the yet unidentified HEGRA
TeV gamma-ray source TeV J2032+4130 in the Cygnus region. In addition, a large
fraction of the Galactic plane has been studied during dedicated scans.
Following the most precise measurements of the energy spectra of the well
known extragalactic objects Mkn 421 and Mkn 501, the blazars H 1426+428 and 1ES
1959+650 have just been established as sources of TeV photons in the last two
years. Extensive multi-wavelength campaigns have been successfully performed
and spectroscopy of these four objects gives important clues for the
understanding of the nonthermal emission processes and also on the optical to
infrared part of the spectrum of the extragalactic background light. Recently,
strong evidence for the nearby giant radio galaxy M 87 being a TeV gamma-ray
emitter has been obtained.
Some of these results are highlighted in this article.Comment: to appear in the Proceedings of the HEP2003 Europhysics Conference in

A Comparison of Ancient Roman and Greek Norms Regarding Sexuality and Gender
Sex, sexuality, and gender norms continue to be a pressing matter in the modern political and social scene, with debates revolving around several important topics such as means of expression, comfort, biology, culture, among many others, too numerous to list entirely. The existence of these issues is not new, however, as every civilization must establish its own norms and mores in regards to these issues. Among the most significant cultures to influence the development of modern western civilizations, the classical Greco-Roman culture which developed throughout the western Mediterranean must be considered amongst the foremost; and their viewpoints of these issues are no different. While nothing exactly matches perfectly today to the classical opinions, it is still imperative to trace the origins of these opinions so that one may be able to follow their development to the modern ideas which exist today. This paper represents research done for two different assignments required as a capstone for the Classical Civilizations degree, showcasing research done in regards in the specific topic area having already been introduced, but showcasing both the Roman norms as well as those of the two most prominent Greek City-State, Athens and Sparta
Creating Visuals for a Start-Up Company
As part of the capstone in the Visual Communication Technology major, this project is intended to help a community member with a visual/graphic need as well as help me to understand the process of being a professional in the field. The main objective was to determine the basic visual needs of a start-up company and how to successfully produce those materials
WISC-III profile patterns of learning disabled children
The present study examined the performance of a heterogeneous population of learning disabled children (N=171) and children with learning disabilities in reading (LD-R), math (LD-M), and reading and math (LD-R+M) on the WISC-III ACID and SCAD subtests (Arithmetic, Coding, Information, Digit Span, and Symbol Search). Archival WISC-III scores of children that have been verified as having a learning disability in fourteen Midwestern school systems were used to answer the research questions in this study. Two different methods of examining performance on the ACID and SCAD subtests were used in this study, the index score method and the profile method. The results showed that the heterogeneous LD sample performed significantly lower on the ACID index than on the SCAD index, p =.017. The subgroups (LD-R, LD-M, LD-R+M) did not significantly differ from each other on ACID index or the SCAD index, p = .108. Also, the ACID and SCAD indexes did not differ for the subgroups, p = .424. However, the Arithmetic subtest was low for the LD-M group relative to the LD-R group. Additionally, the Information subtest was low for the LD-R group relative to the LD-M group. The final index score comparison showed that the Freedom From Distractibility (FD) portion of the SCAD index was significantly lower than the Processing Speed (PS) portion of the SCAD index for the LD-R group, p= .006,
the LD-M group, p = .002, and the LD-R+M group, p= .004. The heterogeneous LD sample performed equally poorly on the ACID and SCAD profiles. However, for the subgroups the LD-M group displayed greater frequencies of the ACID and SCAD profiles than the LD-R or LD-R+M groups. Although the current study had some limitations the results have significant implications for school psychologists assessing students with learning disabilities

Bound by Print: The Baptist Borderlands of Maine and the Canadian Maritimes, 1770-1840
Asynchronous communication was essential for the development of the cross-border and global identities of Baptists in Maine and the Canadian Maritimes between 1770 and 1840. Religious print, especially published association meeting notes and periodicals, extended the reach of itinerant preaching and molded a cross-border community in the Northeast Borderlands between 1790 and 1810. It allowed Baptists to discuss theology, share news about local churches, and expand their community. American Baptists formed international institutions focused on the spread of Protestantism after the War of 1812, and Maine Baptists actively engaged this more global community through financial donations to the new institutions and by engaging with their periodicals as readers and contributors. Maritime Baptists in the post-war period did not pivot to this expansive community as quickly due to economic and political constraints, and their efforts prioritized local churches and domestic missionary efforts into the mid-1820s, after which they participated more actively in the international benevolent movement. Both Maine and Maritime Baptists published their own periodicals by the 1820s. Baptists in both parts of the Northeastern Borderlands had joined the broader Protestant reform movement by the late 1820s, but in doing so the former close ties between Maine Baptists and those in New Brunswick and Nova Scotia were no longer as vital.
Print played a critical role in the transition from cross-border to global identity by offering a medium for discussion. Baptist culture was not homogenous and growing commitments to foreign missions were challenged by some. Print provided a space to debate values and to reshape Maine and Maritime Baptist identities. A study of asynchronous religious print culture is especially important to understand how laypeople engaged this process. Print particularly enriched women’s expression as an influential tool to engage fellow Baptists throughout the Northeastern Borderlands and beyond. Religious print culture was a vital form of social networking that shaped community formation. It helped build cross-border and global religious identities and connected isolated individuals to a larger Baptist community. Then, as now, asynchronous communication has a powerful impact on individuals’ sense of self and place in the world
Validation of Electronic Rectal Thermometry
Electronic rectal thermometry is performed routinely in most medical centers. While electronic thermometry has been validated at the oral site, rectal measurement has not. We performed a controlled study on 84 children comparing mercury-in-glass and electronic thermometry at the rectal site. No significant difference occurred in temperatures between the two methods. We conclude that the electronic thermometer is a valid instrument to measure rectal temperature
The World Wide Web: A Training Tool for Family Resource Management Educators
Cooperative Extension has actively explored new technologies as a means to provide education to its own staff and the general public. The study reported here concerned the development of a Web site used for Extension family resource management training. The study found that Extension educators use the Web for information and support using it for training. Educators appreciated having links that could be considered reliable and accurate. The data also suggest that such sites can provide a refresher to the in-service material, thus reinforcing the learning experience
