A 37-year-old male ruptured the distal biceps brachii tendon performing a gymnastics routine. At Week 8 postsurgery, a bilateral isokinetic test demonstrated a 64 and 50% (at 60° • s-1and 300° • s-1) peak torque deficit between uninjured and injured arms during elbow flexion. The subject participated in a concentric isokinetic exercise program 3 days a week for 4 months. At 1 year postsurgery a bilateral test demonstrated a 14% deficit in peak torque at 60° • s-1, and faster test velocities of 180° • s-1and 300° • s-1indicated higher torques for the injured biceps muscle. The rehabilitation program returned the ruptured biceps to a level of concentric strength nearly equivalent to the contralateral limb at the velocities tested. © 1995 National Strength & Conditioning Association.

Data from an open-ended questionnaire and the comments section of a structured questionnaire were combined and ana-lyzed to determine the challenges faced and alterations in usual daily activities required by mothers caring for a young child at home in a body cast. The sample consisted of 35 mothers who identified themselves as the primary care givers of a child in a body cast. The challenges of caring for a child in a body cast required major adjustments in almost every aspect of the mothers' lives, including household activities, social and community activities, child care activities, personal care activities, occupational activities, and educational activities. © 1995 National Association of Orthopaedic Nurses.

This exploratory investigation relates traditional theories on resistance to change to privatization of the Romanian economy. The authors identified several “inhibitors” which have served to stall Romania’s attempts to achieve a free-market economy. While a lack of practical training in western-style management practices may be a limiting factor, Romanian managers are generally open to change. However, they are still deeply rooted in the thought processes instilled during Romania’s command economy and a belief that the size and economic importance of their firms will serve as buffers against the “agents of change”. To the extent that change is viewed as a threat to their personal interests, resistance can be expected. The question, “what is in it for me?”, must be satisfactorily addressed if Romanian managers are expected to become active partners in implementing necessary changes. © 1999, Nomos Verlagsgesellschaft mbH und Co.

Let X and Y be varieties over a field k; π : X → Y is a quadruple cover of Y if π*script O signX is a locally free, rank 4 script O signY-algebra. If char k ≠ 2, we see that π*script O signX splits as script O signY ⊕ε where ε is a locally free rank 3 sheaf over script O signY, which is locally the "trace zero" module. For each y ∈ Y, we therefore have a rank 4 associative, commutative algebra over script O signY,y. We find that these algebras are parametrized by an affine cone over the Grassmanian G(2, 6) with vertex corresponding to the algebra k[x, y, z]/(x, y, z)2. We then show that a quadruple cover with trace zero module ε over a variety Y is determined by a totally decomposable section η ∈ H0(∧2S2 E* ⊗ ∧3 E). We then examine the case in which the section η has no zeros. Here, each rank 4 algebra may be associated to a pencil of conics. As a special case of this, we look at the work of G. Casnati and T. Ekedahl on Gorenstein covers, and we show that their analysis is the subcase where the pencil of conics has length 4 base locus. Finally, we study the case in which the trace zero module ε is split. In this context, Galois covers, which are covers induced by the action of a group of order 4 on the covering variety X, are also studied.

A group of children was identified as 'late talkers' who were slow in expressive language development (SELD) on the basis of small expressive vocabulary size at 20-34 months of age. The subjects were followed yearly throughout the preschool and early school-age periods in order to track growth in language and related skills. When the subjects were in second grade, their expressive language skills, as indexed by the Developmental Sentence Score, were measured. This measure was used as the outcome variable in regression and discriminant function analyses. Predictor variables included those gathered when the subjects entered the study at age 2. They included measures of early expressive and receptive language by parent report, nonverbal cognitive performance, Bayley Mental Scale score (a combined verbal and nonverbal cognitive measure), phonological skill, motor skills, maladaptive behaviors, social skills, birth order, socioeconomic (SES) level, and gender. Only SES and early expressive language skills predicted expressive language outcome in second grade. Discriminant function analysis revealed these two factors were significant in predicting success (scores above the tenth percentile), along with a contribution of early gross motor skills. The implications of these findings for understanding early language delays are discussed.

We studied nest site and habitat characteristics associated with 75 Great Horned Owl (Bubo virginianus) nests in Connecticut, northern New Jersey, and southeastern New York. Nest sites were categorized as either urban (30) or rural (45) and were compared to data from available habitat (24 random sites for microhabitat; 70 random sites for macro-habitat). Urban nest trees were significantly larger in diameter and taller than rural nest trees, and accordingly, nests were higher in urban nest trees as well. Urban nest sites were significantly different than random sites for all eight habitat variables, but rural nests were significantly different for only five variables. Urban nests were significantly different than rural nests for five of eight habitat variables. Only urban owl nests had significantly lower site basal area, higher conifer composition, and lower shrub cover. Both urban and rural owl nests showed lower canopy cover and closer proximity to forest edge, paved roads, human habitation, and water than random sites. Although both urban and rural Great Horned Owls demonstrated habitat selection (use different from availability), urban owls showed a stronger degree of selection, probably because of the greater complexity of habitats available in the urban landscape.

Because clients are demanding better health care for their pets, more advanced and quicker techniques for obtaining a diagnosis are essential. Veterinary endoscopy gives veterinarians and clients a noninvasive option for evaluating diseased tissue without surgical intervention. Although patients must be anesthetized, they often are released from the veterinary facility on the same day the procedure is performed. Technicians play a vital role in communication between veterinarians and clients and provide valuable procedural skills during the endoscopy.

A new approach is presented for the observation and analysis of diffraction phenomena. Using the discussed procedures, direct comparison between measured light intensity and theoretical predictions is possible. A modified version of a Poisson spot experiment where the resulting diffraction pattern is recorded by a Sanyo vidicon camera is presented. A double slit experiment is also discussed, demonstrating the quantitative possibilities while addressing detector linearity. A video signal is connected directly to a computer and analyzed using public domain software. This is an excellent arrangement for demonstrations, student labs, or a more general diffraction experiment. © 1999 American Association of Physics Teachers.

Centroptilum ozarkensum, new species is described from distinctive adult males collected from springs within the Ozark National Scenic Rivers area of southeastern Missouri. The adult male of this species is similar to the widespread species C. album, hut is easily distinguished from it by color and morphological characters.

We investigated the response of the forest raptor community to broadcasts of all potentially occurring raptors in a New Jersey watershed. Raptors were systematically surveyed using high-volume broadcasts of conspecific and heterospecific calls during the breeding season at a total of 81 survey stations. Results showed 107 responses from 10 species of breeding raptors following 891 broadcasts of 11 species. Among responses that occurred during or after broadcasts, at least 50% of the forest raptor species responded to heterospecific calls. Response rates to conspecific or heterospecific broadcasts were significantly different between hawks (68% heterospecific) and owls (26% heterospecific), suggesting that hawks showed greater heterospecific conflict than members of the owl guild. The hawk guild had a higher species packing (six versus four species) which is thought to increase the likelihood of competition in the community. In addition, most hawks probably need to re-establish territories each spring because the vast majority of them will migrate south for the winter. In contrast, most of the owl guild members are permanent residents and territories may be more permanent. Overall, the prevalence of heterospecific response is an indicator that current competition exists and continues to shape present-day community structure among forest raptors.

The purpose of this investigation was to identify dynamic balance strategies used by 18 boys and girls who were deaf. Each child was simultaneously videotaped from the frontal and sagittal planes while walking forward on a balance beam and stepping over a stick placed knee high. Next their performance was evaluated on a pass-fail basis. Following testing, each participant was assigned to the respective group (pass n = 9; fail n = 9) for kinematic analysis. Based on a discriminant function analysis of the data, head and trunk ranges of motion (ROM) were significant (p < .05) predictors of pass/fail performance. Children in the fail group had significantly greater head and trunk sway causing them to lose balance. Factors contributing to poor dynamic balance among children who are deaf are discussed as are implications for intervention and further research.

The Foxwoods Casino Resort owned by the Mashantucket Pequots of Connecticut is the largest gambling casino in the Western world. The Pequots' Connecticut location enabled the tribe to open a casino, with accessibility to a large market and limited competition. The opening of Foxwoods is also the result of changes in relationships between Americans and Indians and shifts in American attitudes toward gambling. As attitudes and laws change, however, there is little chance that another Indian Foxwoods will be created here or elsewhere in the United States.

The aesthetics of Thorstein Veblen (1857-1929) have been evaluated by aestheticians and social scientists of various ideological persuasions. Because of Veblen's stature as an American critical theorist and the debate which has ensued over the nature of his aesthetics, further efforts to both clarify and extrapolate from them are self-justificatory. The focus here is on (1) Veblen's view of aesthetic experience, (2) the nature of the non-invidiously beautiful in his aesthetics, (3) his distinction between pure and applied art forms and its importance to the common person and (4) the social basis and artistic consequences of the non-invidious as exemplified in the painting of the American artist Winslow Homer (1836-1910). Problematic areas in Veblen's social theory and aesthetics are addressed and a non-invidious aesthetic of countervailence articulated using Homer's work. Copyright © 1998 SAGE Publications.

We studied the species richness and distribution of the forest raptor community in a New Jersey watershed in relation to urbanization. Raptors were systematically surveyed using high volume broadcasts of conspecific and heterospecific calls during the breeding season at a total of 81 survey stations. Ten habitat variables relevant to urbanization were measured at each survey station using topographic maps and aerial photographs. Results showed a community composed of 10 species of breeding raptors. Buteo lineatus, Accipiter gentilis and Strix varia showed a significant avoidance of suburban habitat, whereas B. jamaicensis and Bubo virginianus had a greater tendency to occupy such areas. Lowland habitat was significantly selected by S. varia, B. lineatus and A. cooperii, a habitat usually most susceptible to development in the study region. Raptor species richness showed a strong positive correlation (r = 0.79, P < 0.01) with wilderness area size. No wilderness area less than 1000 ha had more than four raptor species while four to eight species were found in areas from 1000-8000 ha. Utilization of three increasing size classes of wilderness areas showed increasing trends for B. lineatus, A. gentilis and S. varia, and decreasing trends for B. jamaicensis and Bubo virginianus. © 1997 The Raptor Research Foundation, Inc.
