Twenty-four base pairs of the human antioxidant response element (hARE) are required for high basal transcription of the NAD(P)H:quinone oxidoreductase1 (NQO1) gene and its induction in response to xenobiotics and antioxidants. hARE is a unique cis-element that contains one perfect and one imperfect AP1 element arranged as inverse repeats separated by 3 bp, followed by a “GC” box. We report here that Jun, Fos, Fra, and Nrf nuclear transcription factors bind to the hARE. Overexpression of cDNA derived combinations of the nuclear proteins Jun and Fos or Jun and Fra1 repressed hARE-mediated chloramphenicol acetyltransferase (CAT) gene expression in transfected human hepatoblastoma (Hep-G2) cells. Further experiments suggested that this repression was due to overexpression of c-Fos and Fra1, but not due to Jun proteins. The Jun (c-Jun, Jun-B, and Jun-D) proteins in all the possible combinations were more or less ineffective in repression or upregulation of hARE-mediated gene expression. Interestingly, overexpression of Nrf1 and Nrf2 individually in Hep-G2 and monkey kidney (COS1) cells significantly increased CAT gene expression from reporter plasmid hARE-thymidine kinase-CAT in transfected cells that were inducible by β-naphthoflavone and tert-butyl hydroquinone. These results indicated that hARE-mediated expression of the NQO1 gene and its induction by xenobiotics and antioxidants are mediated by Nrf1 and Nrf2. The hARE-mediated basal expression, however, is repressed by overexpression of c-Fos and Fra1.

Across the boreal forest of North America, lynx populations undergo 10-year cycles. Analysis of 21 time series from 1821 to the present demonstrates that these fluctuations are generated by nonlinear processes with regulatory delays. Trophic interactions between lynx and hares cause delayed density-dependent regulation of lynx population growth. The nonlinearity, in contrast, appears to arise from phase dependencies in hunting success by lynx through the cycle. Using a combined approach of empirical, statistical, and mathematical modeling, we highlight how shifts in trophic interactions between the lynx and the hare generate the nonlinear process primarily by shifting functional response curves during the increase and the decrease phases.

The study of psychopathy is still in early stages with regard to gender differences. Historically, the majority of research has been conducted on male populations, resulting in a gender-biased construct that does not appear to be generalizable to female populations. This paper provides a review of the existing literature on psychopathy, as well as research on inherent gender differences (biology, chemistry, socialization, etc.). Connections between these bodies of research are supposed and suggestions for future study are provided.

La liebre ibérica (Lepus granatensis) es una especie de gran valor en los ecosistemas mediterráneos españoles y por esta razón, su conocimiento ecológico y su relación con los factores que influyen en la heterogeneidad espacial son esenciales para su conservación y manejo. El objetivo de este trabajo es conocer las variaciones de la abundancia de la liebre ibérica en el Parque Natural de la Sierra de Mariola, situado entre las provincias de Alicante y Valencia, en el periodo 2009-2010, y su distribución en las principales matrices del paisaje de una zona de montaña del mediterráneo peninsular. Las abundancias relativas de liebre se han obtenido a partir de transectos estratificados de 1.000 m de longitud. El mayor índice kilométrico de abundancia (IKA) de liebres tiene lugar en primavera (IKA medio de 0,26 liebres/km), y disminuye hasta el invierno (IKA medio de 0,075 liebres/km). La mayor abundancia de liebres se obtiene en la matriz de cultivos de secano (IKA medio de 0,32 liebres/km). Las matrices de vegetación natural y abandono presentan bajo número de liebres, con valores de IKA medios de 0,06 y 0,04 liebres/km respectivamente.

Los principales avances en el conocimiento de las tres especies de liebre presentes en la Península Ibérica (dos de ellas endémicas) tuvieron lugar a finales del siglo XX con la realización de estudios sobre genética, morfología y ecología descriptiva. Durante los años 90 y 2000, se ha profundizado fundamentalmente en aspectos genéticos y evolutivos, en la definición de factores ambientales determinantes de su distribución, en el estado sanitario y en el comportamiento espacial. En lo que respecta a los estudios sobre dinámica poblacional, se dispone únicamente de trabajos locales con metodologías diversas y series de datos generalmente cortas, lo que impide realizar una interpretación conjunta y sólida de los datos. Esta falta de información conlleva que las bases técnicas para determinar un adecuado aprovechamiento cinegético sean en la mayoría de los casos insuficientes. Además, las tres especies se encuentran fuertemente ligadas al medio agrícola y ganadero, por lo que determinar los factores relativos al manejo de estos medios que afectan a las liebres resulta esencial, especialmente debido al declive general de la mayor parte de las especies silvestres ligadas a estos espacios. ¿Será el sector científico-técnico capaz de avanzar en el conocimiento de la dinámica poblacional y el efecto del manejo agroganadero para una mejor gestión de las liebres ibéricas?

This dissertation relates job desires and outcomes to the Dark Personality (Psychopathy, Machiavellianism, Narcissism, Low Agreeableness, Low Honesty-Humility) in the United States Army. It purports that individuals high on the Dark Personality desire more power, money, and status, and that they obtain jobs that afford them these luxuries by using manipulation at work. Two pilot studies used samples of United States Army members to create and test index variables: Dark Personality, Total Manipulation in the workplace, Desire for Job Success, and Total Job Success in the Army. Individual personality traits, manipulation tactics, and job desires were examined in secondary analyses. Using a sample of 468 United States Army Members, central analyses indicated that Army members high on the Dark Personality desired Job Success. Likewise, army members higher on the Dark Personality used more Manipulation tactics at work, including the egregious tactics. Yet, using more Manipulation tactics at work predicted lower levels of Job Success in the Army. Most manipulation tactics had a negative impact on Job Success, with the exception of soft tactics like Reason and Responsibility Invocation. Together, these results indicate that selective use of soft manipulation predicted Job Success, but use of more manipulation tactics predicted less Job Success in the Army. Curvilinear results indicated that being either very low or very high on the Dark Personality predicted more Job Success in the Army, whereas having intermediate levels of the Dark Personality predicted less Job Success. Finally, possessing the Dark Personality and using more Manipulation tactics at work, together, predicted less Job Success in the Army. Collectively, the results indicate that army members with intermediate levels of the Dark Personality want more powerful and high paying jobs, yet their strategy of manipulating their coworkers to move up the job ladder does not result in higher ranking, higher paying Army positions. However, Army members highest on the Dark Personality achieved job success, defying the maladaptive influence that antisocial personality traits and manipulative behaviour had on job success for most Army members. Therefore, this dissertation indicates that successful corporate scoundrels exist in the Army, but there are few of them.
