Lubbock Christian University is a private Christian university associated with the Churches of Christ located in Lubbock, Texas, in the United States. Founded as Lubbock Christian School in 1954, the institution was known as Lubbock Christian College from 1956 to 1988. A fall 2012 count showed 2,135 students enrolled at Lubbock Christian University, of which nearly 500 are graduate students. LCU is located just off Loop 289. Wikipedia.

Many riverine cyprinids native to the Great Plains of North America are members of a reproductive guild that broadcast spawns pelagic, semi-buoyant ova. The task of fully understanding and appreciating the complexity of the reproductive ecology of this guild has been difficult. Although various efforts to understand their reproductive ecology have been conducted over the last 60 years, the results of these studies and the conclusions drawn from them have been inconsistent and oftentimes seemingly contradictory. The result has been varied and ill-informed conservation and management strategies based on an incomplete understanding of the reproductive ecology of these fish. We used gonadosomatic index, oocyte development, oocyte size distribution, and histological techniques to assess the reproductive ecology of sharpnose shiner Notropis oxyrhynchus in the upper Brazos River, Texas, between April 2003 and March 2005. Histological analyses of ovarian tissue revealed that reproduction occurred over a six-month period between April and September during which individual fish spawned multiple times. Patterns in gonadosomatic index, oocyte development, and oocyte size distribution indicated that sharpnose shiner spawn asynchronously except during periods of increased streamflow when spawning is synchronized within populations. Reproductive ecology of the sharpnose shiner reported in this study appears to be nearly identical to that recently reported for two other broadcast spawning cyprinids in the Great Plains, indicating that a more complete and consistent understanding of their reproductive ecology is beginning to emerge. We attribute this to the inclusion of both individual and population-scale analyses used in the most recent studies. © 2014 Springer Science+Business Media Dordrecht.

Habitat associations of sharpnose shiner (Notropis oxyrhynchus) in the upper Brazos River, USA, were studied over a two-year period. We used generalized linear models with a logit link to assess the influence of individual physical and chemical habitat variables on the presence of sharpnose shiner at the microhabitat scale. Our models indicated that depth was the only habitat variable that significantly predicted sharpnose shiner presence during the first year of the study and that current velocity was the only variable that significantly predicted sharpnose shiner presence during the second year. Monthly plots of fitted regression estimates superimposed over frequency distributions for both significant variables revealed a distinct pattern of habitat use related to habitat availability. When only a narrow range of depths and current velocities was available, sharpnose shiner occurred more frequently in deeper and swifter microhabitats. In contrast, during periods with the greatest depths and current velocities, sharpnose shiner presence decreased with increasing depth and current velocity. Our results suggest that sharpnose shiner in the Brazos River exhibits habitat preferences but these preferences are conditional, based on the range of habitats available on a given date. © 2013 Taylor & Francis.

Arsenic is a carcinogenic element that occurs naturally in the environment. High levels of arsenic are found in water in some parts of the world, including Texas. The aims of this study were to determine the distribution of arsenic in muskmelon (Cucumis melo) plants accumulated from arsenic spiked water and to observe effects on plant biomass. Plants were grown and irrigated using water spiked with variable concentrations of arsenic. Inductively coupled plasma mass spectrometry was used to quantify arsenic in different parts of the plant and fruit. Under all conditions tested in this study, the highest concentrations of arsenic were found in the leaves, soil, and roots. Arsenic in the water had no significant effect on plant biomass. Fruits analyzed in this study had arsenic concentrations of 101 μg/kg or less. Consuming these fruits would result in less arsenic exposure than drinking water at recommended levels. © 2016 Springer Science+Business Media New York

Background: The well-documented increases in obesity and unhealthy dietary practices substantiate the need for evidence-based tools that can help people improve their dietary habits. The current spread of mobile phone-embedded cameras offers new opportunities for recording food intake. Moreover, the act of taking pictures of food consumed may enhance visual consciousness of food choice and quantity. The present study aimed to assess the effect of using cell phone pictures to record food intake on energy intake and food choice in college students. The effectiveness and acceptability of cell phone picture-based diet recording also was assessed. Methods: A repeated measures crossover design was used. One group of participants entered their food intake online during 3 days based on their memory, although a second group recorded their food intake using cell phone pictures as their reference. Participants then crossed over to complete 3 more days of diet recording using the alternate method. Focus groups were conducted to obtain feedback on the effectiveness and acceptability of cell phone picture-based diet recording. Results: Intake of meat and vegetable servings were significantly higher in the memory period compared with the cell phone period, regardless of the order. Results from the focus group indicated a positive attitude toward the use of cell phone pictures in recording food intake and an increased awareness of food choice and portion size. Linking Evidence to Action: Cell phone pictures may be an easy, relevant, and accessible method of diet self-monitoring when aiming at dietary changes. Future trials should combine this technique with healthy eating education. © 2015 Sigma Theta Tau International.

We apply the Communication Theory of Identity to investigate how patients display their ethnic identities during intercultural patient-provider interactions. Ethnic identity displays play a large part in reflecting patients' and providers' assumptions about the other, as well as their communicative needs. We collected paper-and-pencil responses from a convenience sample of providers and their patients, and conducted a constant comparative analysis of their open-ended reports of a recent intercultural medical interview. The results revealed how both parties viewed their roles in intercultural medical encounters and how they looked for accommodative behaviors from the other party. We draw implications for new applications and future developments of the Communication Theory of Identity and Communication Accommodation Theory. © 2011 The Author(s).
