Introduction: We examined the individual patterns of responses for electromyographic (EMG) amplitude and mean power frequency (MPF) during incremental treadmill running. Methods: Nine physically active men performed incremental treadmill running at a constant grade of 1%. The EMG signal was recorded from the 3 superficial quadriceps femoris muscles during the work bout. Results: The results of the polynomial regression indicated that the linear model best fit the data for the composite data for all 3 muscles and the majority (7 of 9) of subjects. There were no consistent patterns of responses for the EMG MPF responses. Also, there were no significant (P>0.05) muscle × running velocity interactions for EMG amplitude and MPF. Conclusions: These results indicate consistent patterns of responses for EMG amplitude during incremental treadmill running, regardless of which muscle was studied. © 2013 Wiley Periodicals, Inc.

Teachers of English as a Foreign Language (EFL) in Taiwan often use an outdated lecture-memorization methodology resulting in low motivation, confidence, and ability on the part of students. Innovative educators are exploring use of technology, such as videoconferences with native speakers, to enrich the classroom; however few guidelines have been developed for effective videoconference instructional design. This study used a survey methodology, Exploratory Factor Analysis, and Structural Equation Modeling to examine which elements of learning via videoconferencing most beneficially affect motivation, confidence, and ability. The study found that long-term changes in ability are best predicted by enjoyment of the learning experience. The data also suggested that even a small amount of authentic interaction in English made students more comfortable in applying their skills, more confident in what they learned, and more inspired to make global, cross-cultural connections. Therefore, EFL instructors should strive to use student-centered active learning and to offer their students interactions with native speakers, including interactions via distance technology. © International Forum of Educational Technology & Society (IFETS).

Dennis Joslin, Ph.D., will retire from his position as president and CEO of Nebraska Methodist College effective July 31, 2017. Dr. Joslin has served Nebraska Methodist College for the past 41 years after beginning his career in healthcare as a critical care staff nurse. Joslin then moved into teaching as a faculty member at Methodist School of Nursing. Prior to becoming president and CEO he held many positions within the college including executive vice president, vice president of academic affairs, dean of academic affairs and director of curriculum. Dr. Joslin earned his Bachelor of Science in Nursing from the University of Iowa, his Master of Science in Nursing from the University of Nebraska Medical Center and his Ph.D. in Higher Education Leadership from the University of Nebraska-Lincoln. Throughout his career, Joslin has promoted the expansion of roles and education for nursing and allied health professionals. As one of the first men to enter nursing in the 1970’s, Joslin saw the need for an expanding number of male nurses. The promotion of nursing as a profession for men is something that Joslin continues to support through his participation as a charter member in the Nebraska Chapter of the American Association for Men in Nursing. Under Joslin’s executive stewardship, the college experienced substantial transformation which included the first capital campaign for the college, the design, construction and opening of a state-of-the-art campus, annual record enrollments for each of the past 15 years (resulting in nearly tripling enrollment to 1,100 students), the launching of degree offerings at the doctoral level and the expansion of offerings at the master’s, bachelor’s and associate’s degree levels as well as several certificate level offerings. To ensure that the college’s mission of “promoting the health and well-being of the community” is realized, the college has developed numerous partnerships throughout the community to extend the reach of NMC students, faculty and staff. “The growth we’ve established, along with our consistently high job placement rates, lend credence to the idea that we are a premier school in the Omaha area for a healthcare education,” said Dr. Joslin. Deb Carlson, Ph.D., executive vice president, will assume the position of president and CEO on Aug. 1, 2017. The Nebraska Methodist College Board of Directors unanimously selected her to succeed Joslin as the next president. Carlson has been with NMC for 14 years and has served as a faculty member in the Arts and Sciences division, president of the Faculty Senate, director of the Office of Institutional Research, vice president of operations and, for the past three years, executive vice president. “Dr. Carlson is an outstanding educator and administrator who brings over 20 years of higher education experience from the University of Nebraska and Wayne State College,” said Joslin of his successor. “As a cognitive psychologist, she really understands people and excels in organizational development, strategic planning and accreditation. Deb is committed to serving the community with a focus on community-based healthcare, a direct reflection of the mission of the college.” The Omaha, Nebraska-based Nebraska Methodist College – the Josie Harper Campus has been teaching the meaning of care for 125 years and counting. An affiliate of Methodist Health System, NMC offers certificate, associate’s, bachelor’s, master’s and doctoral degrees both on campus and online. Nebraska Methodist College is accredited by The Higher Learning Commission of the North Central Association of Colleges and Schools.

Effect of positioning of the cyanoacrylic acid anchoring group on ring periphery of phenothiazine dye on the performance of dye-sensitized solar cells (DSSCs) is reported. Two types of dyes, one having substitution on the C-3 aromatic ring (Type 1) and another through the N-terminal (Type 2), have been synthesized for this purpose. Absorption and fluorescence studies have been performed to visualize the effect of substitution pattern on the spectral coverage and electrochemical studies to monitor the tuning of redox levels. B3LYP/6-31G* studies are performed to visualize the frontier orbital location and their significance in charge injection when surface modified on semiconducting TiO2. New DSSCs have been built on nanocrystalline TiO2 according to traditional two-electrode Grätzel solar cell setup with a reference cell based on N719 dye for comparison. The lifetime of the adsorbed phenothiazine dye is found to be quenched significantly upon immobilizing on TiO2 suggesting charge injection from excited dye to semiconducting TiO2. The performances of the cells are found to be prominent for solar cells made out of Type 1 dyes compared to Type 2 dyes. This trend has been rationalized on the basis of spectral, electrochemical, computational, and electrochemical impedance spectroscopy results. © 2012 American Chemical Society.

Novel photosynthetic reaction center model compounds of the type donor2-donor1-Acceptor, composed of phenothiazine, BF2-chelated dipyrromethene (BODIPY), and fullerene, respectively, have been newly synthesized using multistep synthetic methods. X-ray structures of three of the phenothiazine-BODIPY intermediate compounds have been solved to visualize the substitution effect caused by the phenothiazine on the BODIPY macrocycle. Optical absorption and emission, computational, and differential pulse voltammetry studies were systematically performed to establish the molecular integrity of the triads. The N-substituted phenothiazine was found to be easier to oxidize by 60 mV compared to the C-substituted analogue. The geometry and electronic structures were obtained by B3LYP/6-31G(dp) calculations (for H, B, N, and O) and B3LYP/6-31G(df) calculations (for S) in vacuum, followed by a single-point calculation in benzonitrile utilizing the polarizable continuum model (PCM). The HOMO-1, HOMO, and LUMO were, respectively, on the BODIPY, phenothiazine and fullerene entities, which agreed well with the site of electron transfer determined from electrochemical studies. The energy-level diagram deduced from these data helped in elucidating the mechanistic details of the photochemical events. Excitation of BODIPY resulted in ultrafast electron transfer to produce PTZ-BODIPYC+-C60C; subsequent hole shift resulted in PTZC+-BODIPY-C60C charge-separated species. The return of the charge-separated species was found to be solvent dependent. In nonpolar solvents the PTZC+-BODIPY-C60C species populated the 3C60∗ prior to returning to the ground state, while in polar solvent no such process was observed due to relative positioning of the energy levels. The 1BODIPY∗ generated radical ion-pair in these triads persisted for few nanoseconds due to electron transfer/hole-shift mechanism.

A multimodular donor-acceptor tetrad featuring a bis(zinc porphyrin)-(zinc phthalocyanine) ((ZnP-ZnP)-ZnPc) triad and bis-pyridine-functionalized fullerene was assembled by a "two-point" binding strategy, and investigated as a charge-separating photosynthetic antenna-reaction center mimic. The spectral and computational studies suggested that the mode of binding of the bis-pyridine-functionalized fullerene involves either one of the zinc porphyrin and zinc phthalocyanine (Pc) entities of the triad or both zinc porphyrin entities leaving ZnPc unbound. The binding constant evaluated by constructing a Benesi-Hildebrand plot by using the optical data was found to be 1.17×105 M-1, whereas a plot of "mole- ratio" method revealed a 1:1 stoichiometry for the supramolecular tetrad. The mode of binding was further supported by differential pulse voltammetry studies, in which redox modulation of both zinc porphyrin and zinc phthalocyanine entities was observed. The geometry of the tetrad was deduced by B3LYP/6-31G* optimization, whereas the energy levels for different photochemical events was established by using data from the optical absorption and emission, and electrochemical studies. Excitation of the zinc porphyrin entity of the triad and tetrad revealed ultrafast singlet-singlet energy transfer to the appended zinc phthalocyanine. The estimated rate of energy transfer (kENT) in the case of the triad was found to be 7.5×1011 s-1 in toluene and 6.3×10 11 s-1 in o-dichlorobenzene, respectively. As was predicted from the energy levels, photoinduced electron transfer from the energy-transfer product, that is, singlet-excited zinc phthalocyanine to fullerene was verified from the femtosecond-transient spectral studies, both in o-dichlorobenzene and toluene. Transient bands corresponding to ZnPc+ in the 850 nm range and C60 - in the 1020 nm range were clearly observed. The rate of charge separation, kCS, and rate of charge recombination, kCR, for the (ZnP-ZnP)-ZnPc+:Py 2C60 - radical ion pair (from the time profile of 849 nm peak) were found to be 2.20×1011 and 6.10×108 s-1 in toluene, and 6.82×10 11 and 1.20×109 s-1 in o-dichlorobenzene, respectively. These results revealed efficient energy transfer followed by charge separation in the newly assembled supramolecular tetrad. Artificial photosynthesis: Occurrence of ultrafast energy transfer (EnT) and electron transfer leading to the formation of a charge-separated (CS) state is demonstrated in a new donor-acceptor supramolecular tetrad comprising a bis(zinc porphyrin)-(zinc phthalocyanine) linked to fullerene as a photosynthetic antenna-reaction center mimic (see scheme). © 2014 WILEY-VCH Verlag GmbH & Co.

We report a facile Ru-catalyzed route to alkenes from unsaturated fatty acids (alkenoic fatty acids) via readily accessible catalyst precursors, [Ru(CO)2RCO2]n and Ru3(CO)12. The catalyst apparently functions in a tandem mode by dynamically isomerizing the positions of double bonds in an aliphatic chain and, subsequently, decarboxylating specific isomers with lower activation barriers. Substrates capable of tandem isomerization-decarboxylation processes (oleic acid, undecylenic acid) are readily converted to mixtures of alkenes. A catalytic cycle is proposed that relies on isomerization positioning double bonds proximate to the acid function to enable facile decarboxylation. To elucidate the proposed mechanistic pathway, substrates that do not undergo decarboxylation under these catalytic conditions (methyl oleate) are compared with those that cannot isomerize the position of unsaturation (cinnamic acid). Both were shown to be operational under these catalytic reaction conditions. Another illustrative comparison shows that the saturated octadecanoic acid is 28 times less reactive than the unsaturated counterpart when reacted using this precatalyst. © 2014 American Chemical Society.

Service-learning is a form of experiential learning that integrates curriculum objectives to address needs in the community. It also provides students with an opportunity to apply geospatial technology concepts in a real-world setting. This paper describes a service-learning project requiring students to create an interactive Google Map depicting historic buildings and artwork for the City of Wayne, Nebraska. Students create maps by using handheld GPS receivers and editing HTML and JavaScript. The objectives of this project align with several building blocks and critical work functions in the Geospatial Technology Competency Model (GTCM). This model, developed in 2010 by the U.S. Department of Labor, attempts to identify the knowledge and abilities needed in the geospatial industry workforce. In addition the methods, assessment, and challenges for developing and executing this project are described. Copyright © 2015, IGI Global.

The need to understand and manage ecosystems at larger regional to continental scale macrosystem levels is becoming increasingly crucial with global climate changes and impacts of exotic plants and animals in freshwater rivers and lakes. Macrosystem management requires an understanding of how different levels of spatial complexity (within a stream reach to entire river valley scales) and biotic organization (populations to ecosystems) affect the functioning of rivers and lakes. The present study will provide this information for 18 rivers spread equally between the two largest temperate steppe biomes of the world: the North American Great Plains and the Euro-Asian Steppes (including those in Mongolia). This project will provide research experiences for under-represented participants (particularly rural and Native American students), stimulate STEM program recruitment in largely under-represented (EPSCoR) states, support some faculty and students at primarily undergraduate institutions, and contribute to scientific education at both graduate and undergraduate institutions in two countries.

These rivers flow through 3 major types of ecoregions within these temperate steppe biomes: mountain steppe shrublands, short-to-tall grasslands, and semi-arid shrublands. Scientists and students from the USA and Mongolia will sample the structure and functioning of these 18 rivers in a variety of hydrogeomorphic areas, such as constricted, meandering, braided, and anastomosing channel sections. Despite their similarity in biome and ecoregional types, the river macrosystems of the Great Plains and the Mongolian steppes vary substantially in fauna, flora, and community through ecosystem functioning. These variations result from differences in climatic patterns, the degree of riverine landscape modification (e.g., by dams, levees, and riparian modification), and the naturalness of the resident fauna. For example, most rivers in the USA contain some dams and many exotic fauna have been introduced, while the vast majority of Mongolian rivers contain no dams and their aquatic fauna is almost exclusively natural and different from those in the USA. Moreover, the Central Asian subcontinental area of Mongolia has one of the strongest warming signals on earth, with air temperatures rising three times faster than the overall northern hemisphere average. Consequently, riverine macrosystems in the USA can help predict changes to Mongolian rivers as a result of pending dam construction and possible species introductions to some rivers, while knowledge of responses of Mongolian macrosystems to more rapid climatic changes can help predict future effects in U.S. rivers. Therefore, this projects goals are to: (a) compare and contrast hierarchical scaling relationships and effects of system drivers and cross-scale interactions on rivers in similar biomes and ecoregions of the two continents; and (b) evaluate effects of climatic changes and anthropogenic disturbance to these river macrosystems.
