Importance of Canals for Florida Largemouth Bass: Lake Griffin, Florida
Authors: Bisping Scott M. , Thompson Brandon C. 
Published: January 2017

Abstract
Canal systems are commonly found across the country and are rarely constructed to increase fish habitat or angling opportunities. From 2009 to 2011, we assessed the benefits of canals to the fishery at Lake Griffin, Florida, by measuring and comparing the Florida Largemouth Bass Micropterus salmoides floridanus population and angler use to the main lake. We used electrofishing, angler creel surveys, and a high-reward tagging study. Results from electrofishing surveys revealed a high relative abundance of Florida Largemouth Bass in the canals, with similar electrofishing catch rates and size structure to those in the main lake. The canal creel showed that anglers used canals throughout the study, with peak use during the spawning season. The tagging study revealed anglers caught Florida Largemouth Bass in canals throughout the 12-mo study and that Florida Largemouth Bass migrated between the lake and canals. We conclude that the canals support a significant portion of the overall angler effort for the Lake Griffin fishery. Failing to consider the canals at Lake Griffin results in substantial underestimates of fish populations, angler use, and the fishery's economic impact. Our data suggest, however, that monitoring only the lake section still may represent trends occurring throughout the entire body of water, resulting in lowering sampling time and financial requirements. Fishery managers can identify any impacts canal systems or other lake sections may have to the fishery by including additional sections of a body of water into their sampling protocol.

Abstract. In situ single particle analysis of ice particle residuals (IPRs) and out-of-cloud aerosol particles was conducted by means of laser ablation mass spectrometry during the intensive INUIT-JFJ/CLACE campaign at the high alpine research station Jungfraujoch (3580 m a.s.l.) in January–February 2013. During the 4-week campaign more than 70 000 out-of-cloud aerosol particles and 595 IPRs were analyzed covering a particle size diameter range from 100 nm to 3 µm. The IPRs were sampled during 273 h while the station was covered by mixed-phase clouds at ambient temperatures between −27 and −6 °C. The identification of particle types is based on laboratory studies of different types of biological, mineral and anthropogenic aerosol particles. The outcome of these laboratory studies was characteristic marker peaks for each investigated particle type. These marker peaks were applied to the field data. In the sampled IPRs we identified a larger number fraction of primary aerosol particles, like soil dust (13 ± 5 %) and minerals (11 ± 5 %), in comparison to out-of-cloud aerosol particles (2.4 ± 0.4 and 0.4 ± 0.1 %, respectively). Additionally, anthropogenic aerosol particles, such as particles from industrial emissions and lead-containing particles, were found to be more abundant in the IPRs than in the out-of-cloud aerosol. In the out-of-cloud aerosol we identified a large fraction of aged particles (31 ± 5 %), including organic material and secondary inorganics, whereas this particle type was much less abundant (2.7 ± 1.3 %) in the IPRs. In a selected subset of the data where a direct comparison between out-of-cloud aerosol particles and IPRs in air masses with similar origin was possible, a pronounced enhancement of biological particles was found in the IPRs.

Published: January 2017

Abstract. Few field studies examine greenhouse gas (GHG) emissions from African agricultural systems, resulting in high uncertainty for national inventories. This lack of data is particularly noticeable in smallholder farms in sub-Saharan Africa, where low inputs are often correlated with low yields, often resulting in food insecurity as well. We provide the most comprehensive study in Africa to date, examining annual soil CO2, CH4 and N2O emissions from 59 smallholder plots across different vegetation types, field types and land classes in western Kenya. The study area consists of a lowland area (approximately 1200 m a.s.l.) rising approximately 600 m to a highland plateau. Cumulative annual fluxes ranged from 2.8 to 15.0 Mg CO2-C ha−1, −6.0 to 2.4 kg CH4-C ha−1 and −0.1 to 1.8 kg N2O-N ha−1. Management intensity of the plots did not result in differences in annual GHG fluxes measured (P = 0.46, 0.14 and 0.67 for CO2, CH4 and N2O respectively). The similar emissions were likely related to low fertilizer input rates (≤ 20 kg N ha−1). Grazing plots had the highest CO2 fluxes (P = 0.005), treed plots (plantations) were a larger CH4 sink than grazing plots (P = 0.05), while soil N2O emissions were similar across vegetation types (P = 0.59). This study is likely representative for low fertilizer input, smallholder systems across sub-Saharan Africa, providing critical data for estimating regional or continental GHG inventories. Low crop yields, likely due to low fertilization inputs, resulted in high (up to 67 g N2O-N kg−1 aboveground N uptake) yield-scaled emissions. Improvement of crop production through better water and nutrient management might therefore be an important tool in increasing food security in the region while reducing the climate footprint per unit of food produced.

Published: January 2017

Abstract. A new automated method enabling consistent satellite assessment of seasonal lake ice phenology at 5 km resolution was developed for all lake pixels (water coverage  ≥  90 %) in the Northern Hemisphere using 36.5 GHz H-polarized brightness temperature (Tb) observations from the Advanced Microwave Scanning Radiometer for EOS and Advanced Microwave Scanning Radiometer 2 (AMSR-E/2) sensors. The lake phenology metrics include seasonal timing and duration of annual ice cover. A moving t test (MTT) algorithm allows for automated lake ice retrievals with daily temporal fidelity and 5 km resolution gridding. The resulting ice phenology record shows strong agreement with available ground-based observations from the Global Lake and River Ice Phenology Database (95.4 % temporal agreement) and favorable correlations (R) with alternative ice phenology records from the Interactive Multisensor Snow and Ice Mapping System (R = 0.84 for water clear of ice (WCI) dates; R = 0.41 for complete freeze over (CFO) dates) and Canadian Ice Service (R = 0.86 for WCI dates; R = 0.69 for CFO dates). Analysis of the resulting 12-year (2002–2015) AMSR-E/2 ice record indicates increasingly shorter ice cover duration for 43 out of 71 (60.6 %) Northern Hemisphere lakes examined, with significant (p  <  0.05) regional trends toward earlier ice melting for only five lakes. Higher-latitude lakes reveal more widespread and larger trends toward shorter ice cover duration than lower-latitude lakes, consistent with enhanced polar warming. This study documents a new satellite-based approach for rapid assessment and regional monitoring of seasonal ice cover changes over large lakes, with resulting accuracy suitable for global change studies.
Loss and change: The challenges of mothering an adult child with schizophrenia
Authors: Wiens Sandra E. , Daniluk J. C. 
Published: January 2017

A qualitative narrative and cross-narrative research method was used to explore how six mothers of adult children with schizophrenia or schizoaffective disorder experienced personal growth and change. Twenty-four largely unstructured interviews were conducted over the course of two years. The following eight common themes emerged across the narratives: Enduring sadness and loss, Distress and struggle, Fluctuations in hope, Feelings of guilt and regret, Concern about their child’s future, Impact of their child’s mental illness on their other children, Commitment to helping/action, and Personal and relational change. The changes reported by these mothers were set against the backdrop of the nonfinite losses that characterized the realities and uncertainties of their lives since the onset of their child’s mental illness. Implications for mental health practice are addressed based on these findings.

Introduction: Nitric oxide (NO) plays an important role in the ischemia and reperfusion process. In this study, we aimed to examine the effect of L-arginine, tadalafil, and their combination for preventionof the ischemia reperfusion injury after testis torsion in rats.Methods: A total of 40 adult, male Sprague-Dawley rats were allocated into five groups. Three hours of left testicular torsion was performed in each group, excluding the control group. While the ischemia reperfusion (I/R) group had no treatment, I/R + Arg group received L-arginine, I/R + Td group received tadalafil and I/R + Arg + Td group received tadalafil and L-arginine 30 minutes before the detorsion. Then the left testis was untwisted for four hours of reperfusion. After bilateral orchiectomy, lipid peroxidation (LPx) and glutathione (GSH) activities were examined in testicular tissue.Spermatogenesis was evaluated with Johnsen’s score.Results: LPx levels of the I/R group were found to be significantly higher than for groups that received drugs for both testes (p<0.001). GSH levels of the combination group were higher than I/R group inipsilateral testis (p<0.01) and it was significantly higher than other groups for contralateral testis (p<0.001 for I/R group, p<0.01 for I/R + Arg, p<0.05 for I/R + Td). Mean Johnsen’s score of the I/Rgroup was found to be significantly lower than treatment groups in ipsilateral testis (p<0.001 for I/R + Arg + Td group, p<0.01 for other treatment goups) and contralateral testis (p<0.001). The meanJohnsen score of the combination group was significantly higher than that of other treatment groups in ipsilateral testis (p<0.05) and it was significantly higher than in the I/R + Td group in the contralateral testis (p<0.05).Conclusions: L-arginine, tadalafil, and combination of these two molecules showed protective effect against ischemia/reperfusion injury for both testes after unilateral testis torsion.
Chemometrics Expertise in the Links Between Ecotoxicity and Physicochemical Features of Silver Nanoparticles: Environmental Aspects

Published: January 2017

Abstract
Studies of the ecotoxicological aspects of nanomaterials in aquatic environments are scarce. Given the growing variety of nanoparticles (NPs), along with the diversity of aquatic species and environments, the key to promoting sound risk assessment in nanoecotoxicology is understanding the mechanisms that govern the fate of NPs in aquatic environments and their behavior at the NP–biota interface. In this paper, data collected from the literature on ecotoxicological effects observed in aquatic species is discussed and analyzed using multivariate statistics techniques. We expand the knowledge of the environmental impact of silver NPs (AgNPs) by testing the acute toxicity of 47 AgNPs on crustacean eukaryotic organisms (Daphnia magna, Thamnocephalus platyurus, and D. galeata). Physicochemical properties, stabilization agents, toxicological end points, and test media were monitored as adding-outcome factors for the evaluation of environmental effects due to exposure to NPs. The chemometrics expertise performed by the use of hierarchical and nonhierarchical cluster analysis and principal component analysis revealed specific links between the ecotoxicologyand the physicochemical features of NPs and helped in creating specific patterns of NPs discriminated by ecotoxicity levels and physicochemical parameters.
Heidegger en torno al error de la Modernidad: La crítica al dualismo cartesiano de cuerpo y alma (Sein und Zeit, parágrafos 19, 20, 21).

<p align="JUSTIFY"> A partir del pensamiento presentado por Martin Heidegger en <em>Sein und Zeit</em>, podemos elaborar una crítica a la Modernidad filosófica.

El cuerpo como espacialidad ambigua: Somato-política y resistencias corporales en Michel Foucault
Authors: Benavides Franco Tulio Alexander 
Published: January 2017

<p>El cuerpo, en tanto punto de apoyo de las técnicas de poder para la configuración de los sujetos, posee, en la perspectiva foucaultiana, un estatuto complejo: es instrumento a la vez que efecto del poder. Apoyándose en él, el poder avanza; pero al tiempo que es atravesado por el poder, resulta a su vez, inscrito en un espacio de inteligibilidad determinado, investido de una cierta “interioridad” que lo espacializa y lo hace objeto de la mirada. El soporte del poder deviene efecto, pero no deja de ser soporte. El efecto es la forma como el soporte resulta investido por las operaciones del poder sobre él. </p>
La productividad del cuerpo. Apuntes de una fenomenología política en Judith Butler
Authors: González Fisac Jesús 
Published: January 2017

<p>El uso que Butler ha hecho de la fenomenología ha sido constante en su obra y siempre ha tenido cariz político. En los últimos años, al hilo de sus trabajos sobre las ocupaciones del espacio público de la llamada “privamera árabe” (así como sobre sus epifenómenos occidentales, como el movimiento “Occupy Wall Street”), Butler ha revisado el concepto arendtiano de “espacio de aparición”, donde, ciertamente, algo así como una <em>fenomenología política</em> se trasparece totalmente. </p>
Notas sobre la antropología de Kierkegaard
Authors: Viñas Vera Ángel 
Published: January 2017

<p>El presente artículo pretende arrojar algo de luz sobre la comprensión kierkegaardiana del ser humano. La recepción del pensador danés ha subrayado a veces en exceso su carácter fideísta e irracionalista. En este artículo se intenta mostrar que el Kierkegaard no piensa al ser humano desde esas coordenadas. La manera de abordar la desesperación, la infancia y el ser espíritu impedirían encuadrar su aporte filósofico en ellas. Su crítica de la razón así como la relevancia que le da a los acontecimientos y a la alteridad nos ayudan a acercarnos sucintamente al misterio que somos cada uno de nosotros. </p>
Estructura de parentesco y su funcionamiento en El Quijote.
Authors: González-Blanco García Elena 
Published: January 2017

En este estudio, la autora realiza un análisis de frecuencia de palabras en la obra de Cervantes seleccionando entre aquellas que aparecen más de 10 veces en el texto y que pueden dar muestra de la visión de la mujer que aquí se recoge. Sin la pretensión de ofrecer una conclusión determinante, la selección de las palabras y su frecuencia pueden ser un punto de partida para estudios succesivos. En esta primera análisis se concluye que el funcionamiento del sistema de parentesco mascuino funciona con una dependencia del elemento femenino. El tema del «parentesco» es mucho más complejo de lo que la palabra podría sugerir. Aquí se ha partido de los conceptos de parentesco para profundizar en el contenido y en el espíritu de la obra. Es admirable como Cervantes ha contado a través de la anécdota todo el vivir humano de su época y dentro de él ha concedido especial relieve a la reflexión sobre la estabilidad humana en todas sus dimensiones, entre hombres, entre sexos y entre parientes.
In this study, the author performs an analysis of the frequency of words in Cervantes's work, selecting among those that appear more than 10 times in the text and that can show the vision of the woman that is collected here. Without pretending to offer a conclusive conclusion, the choice of words and their frequency can be a starting point for subsequent studies. In this first analysis it is concluded that the functioning of the male kinship system works with a dependence on the female element. The issue of "kinship" is much more complex than the word might suggest. Here we have started from the concepts of kinship to delve into the content and spirit of the work. It is admirable how Cervantes has recounted through anecdote all the human life of his time and within it he has given special prominence to the reflection on human stability in all its dimensions, between men, between sexes and between relatives.

Published: January 2017

BackgroundElectrical stimulation (ES) has been successfully used to treat bone defects clinically. Recently, both cellular and molecular approaches have demonstrated that ES can change cell behavior such as migration, proliferation and differentiation.MethodsIn the present study we exposed rat bone marrow- (BM-) and adipose tissue- (AT-) derived mesenchymal stem cells (MSCs) to direct current electrical stimulation (DC ES) and assessed temporal changes in osteogenic differentiation. We applied 100 mV/mm of DC ES for 1 h per day for three, seven and 14 days to cells cultivated in osteogenic differentiation medium and assessed viability and calcium deposition at the different time points. In addition, expression of osteogenic genes, Runx2, Osteopontin, and Col1A2 was assessed in BM- and AT-derived MSCs at the different time points.ResultsResults showed that ES changed osteogenic gene expression patterns in both BM- and AT-MSCs, and these changes differed between the two groups. In BM-MSCs, ES caused a significant increase in mRNA levels of Runx2, Osteopontin and Col1A2 at day 7, while in AT-MSCs, the increase in Runx2 and Osteopontin expression were observed after 14 days of ES.DiscussionThis study shows that rat bone marrow- and adipose tissue-derived stem cells react differently to electrical stimuli, an observation that could be important for application of electrical stimulation in tissue engineering.
Investigating future precipitation changes over China through a high‐resolution regional climate model ensemble
Authors: Guo Junhong , Huang Guohe , Wang Xiuquan , Li Yongping , Lin Qianguo 
Published: January 2017

AbstractDue to climate change, rising temperature around the world will have a great potential to influence the global hydrologic cycle, thus leading to substantial changes in the spatial and temporal patterns of precipitation. In this study, the effects of global warming on the regional hydrologic cycle, particularly on the spatiotemporal patterns of precipitation, over China are investigated through a high‐resolution regional climate ensemble. In detail, the PRECIS regional climate modeling system is employed to simulate the regional climate over China from 1950 to 2099 with a fine resolution of 25 km, driven by the boundary conditions from a four‐member HadCM3‐based perturbed‐physics ensemble (i.e., HadCM3Q0, Q1, Q7, and Q13) and the ECHAM5 model. Historical simulations of the PRECIS ensemble are first compared to the observations to validate its performance in capturing both the spatial and temporal patterns of precipitation. The comparisons show that the PRECIS ensemble is likely to overestimate precipitation in the south and exhibits slight dry biases in the northwest and southeast coasts of China. The projections from the PRECIS ensemble for future periods (i.e., 2020s, 2050s, and 2080s) are then analyzed to help understand how the regional characteristics of precipitation will be affected in the context of global warming. It is shown that the annual mean precipitation over China is likely to increase throughout the 21st century (i.e., by 0.078 mm/d in 2020s, 0.218 mm/d in 2050s, and 0.360 mm/d in 2080s). This may suggest that the rising temperature due to climate change will intensify the regional hydrologic cycles in China. However, apparent spatial and temporal variations are also reported in the projected precipitations from the PRECIS ensemble. For example, bigger changes in precipitation are usually observed in summer; projected precipitation changes in the southeast are apparently higher than other regions. In addition, the results show that the fluctuation range of the ensemble simulations will increase with time periods from 2020s to 2080s, indicating that the longer the projecting periods, the more uncertain the projections will be.
Photoisomerisierung eines Schalters auf Basis eines chiralen Imins: Verfolgung durch Matrixisolations‐VCD‐Spektroskopie

Published: January 2017

AbstractDie Charakterisierung der Stereochemie kurzlebiger Photoisomerisierungsprodukte ist eine anspruchsvolle Aufgabe bei der Entwicklung molekularer Maschinen, beispielsweise unidirektionaler molekularer Motoren. Diese Zustände sind oft nicht genügend lange stabil, um eine detaillierte Charakterisierung mithilfe konventioneller spektroskopischer Methoden zu ermöglichen. Anhand des strukturell sehr einfachen Campherchinonimins 1 wird gezeigt, wie die Kombination der Matrixisolationstechnik mit der VCD‐Spektroskopie zur Untersuchung der Photoisomerisierung von chiralen Molekülen genutzt werden kann. Es wird gezeigt, dass die Isomere (E)‐1 und (Z)‐1 photochemisch unter kryogenen Bedingungen in einer Argonmatrix erzeugt und anschließend auch die Stereochemie beider Schaltzustände verlässlich charakterisiert werden kann.
