Self-esteem, depression, alcohol consumption and smoking in women who work as prostitutes in the cities of S/Autoestima, depresión, consumo de alcohol y cigarrillo en mujeres que ejercen la prostitución en las ciudades de Santa Marta y Riohacha (Colombia)
Authors: Ceballos Ospino Guillermo Augusto 
Published: February 2015

El objetivo del presente estudio fue establecer la relación entre la autoestima, depresión, consumo de alcohol y cigarrillo en mujeres que ejercen la prostitución en las ciudades de Santa Marta y Riohacha. Se utilizó un diseño trasversal y tipo correlacional, con una muestra de 30 mujeres que ejercen la prostitución en las ciudades de Santa Marta y Riohacha. Los resultados manifiestan que no existen correlaciones entre las variables de estudio. Se concluye que las mujeres que ejercen la prostitución en estas dos ciudades del Caribe colombiano, poseen en su mayoría una depresión moderada y un consumo abusivo de alcohol, sin embargo no tienen problemas con su autoestima, ni con conductas dañinas como el consumo de cigarrillo.
Breaking with the hegemonic position, the road to the acknowledgment and recognition of the social minorities/Ruptura con la postura hegemónica, camino de reconocimiento de las minorías
Authors: Polanía Dussán Germán Andrés 
Published: February 2015

El pensamiento Liberal Clásico estructuró el Estado moderno a través de la teoría del pacto social, la supremacía de laley y el reconocimiento del hombre como un ser racional y autónomo, en donde el valor fundamental es la libertad. Sinembargo, al establecer un Estado se definió una identidad y un orden que nace según la teoría política del mismo pueblo(pacto social). No obstante, al mismo tiempo que promueve esa identidad, está rechazando la diferencia porque legalmente no está reconocida en la generalización establecida por la ley. Por eso, es necesario buscar otros aspectos conceptuales que abra el Estado hegemónico al reconocimiento de la diferencia. Además, Colombia, desde 1991, creó un marco legal para garantizar la vida de las minorías, pero cómo generar una concertación que plantee una real inclusión es el reto actual.
The jungle as a space of multiple abuse. Ecocritical reading of two Mexican novels/La selva como espacio de abusos múltiples. Una lectura ecocrítica de dos novelas mexicanas
Authors: Walczak Grazyna 
Published: February 2015

La selva americana cobra protagonismo desde los primeros relatos de los descubridores y cronistas del Nuevo Mundo, convirtiéndose en la imaginación europea al Paraíso terrenal. A pesar de que esa imagen persiste hasta el siglo XX, existe en la literatura hispanoamericana una tendencia desmitificadora del estereotipo “edénico” de los espacios selváticos. En Balún Canán (1957) de Rosario Castellanos y en Treinta años (1999) de Carmen Boullosa los lugares descritos otrora como paradisiacos se presentan como áreas de exclusión y confinamiento social y cultural, además de que revelan serios problemas ambientales. Este trabajo propone la lectura de los dos textos desde la perspectiva de la ecocrítica que incluye el análisis de los problemas humanos en conexión con los de la naturaleza. La discusión de los conflictos que revelan las narraciones de las protagonistas de ambas novelas permite valorar las obras de Castellanos y de Boullosa como un testimonio de dilemas sociales que son inseparables de los problemas ambientales puesto que son provocados por el mismo poder.
The Impact of Education and Culture on the Retention and Propagation of French in Ontario, Canada/Impacto de la educación y cultura en la retención y propagación del francés en Ontario, Canadá
Authors: Natsis James 
Published: February 2015

La identidad franco-ontariana como grupo lingüístico tiene profundas raíces históricas además de una base numérica considerable. Sin embargo, su localización dentro de un baluarte norteamericano dominado por lo anglosajón, el cual no sólo emerge fuertemente en términos lingüísticos, sino también en términos culturales, presenta retos especiales en lo concerniente a la retención y propagación de la lengua y la cultura. Para enfrentar esta preocupación, la provincia ha logrado un esfuerzo cooperativo de iniciativas gubernamentales y comunitarias para asegurar el futuro de la francofonía ontariana.
Youth Collectives as participative ways for the construction of an active citizenship/Colectivos juveniles como formas participativas de construcción de ciudadanía activa
Authors: Correa Rafael Arturo Pabón 
Published: February 2015

En este artículo de reflexión se plantearán desde una perspectiva argumentativa las características que diferencian e identifican a los colectivos juveniles frente otro tipo de agrupaciones políticas tradicionales, analizando la coyuntura sobre la cual transitan los jóvenes en la actualidad y el papel histórico que han jugado en la consecución de cambios sociales en contraposición al sistema político hegemónico. Desde un punto de vista reflexivo se argumentará acerca de la validez de este tipo de manifestaciones como formas en las que los jóvenes pueden alcanzar el estatus de ciudadanos en la sociedad contemporánea, en cuanto los procesos que llevan a cabo les insertan de forma activa en la esfera pública permitiendo, gracias a sus estructuras organizativas específicas, el desarrollo de formas participativas de comunicación que generan un sentido de pertenencia más alto del que les merecen las instituciones representativas del sistema político tradicional.
Response of Deeproot Sedge (Cyperus entrerianus) to Herbicide and Prescribed Fire in Texas Coastal Prairie

Published: February 2015

AbstractIntroduced accidentally from South America, deeproot sedge is rapidly expanding in a variety of habitats throughout the southeastern United States. Of particular concern is its rapid expansion, naturalization, and formation of monocultures in Texas coastal prairie, one of the most imperiled temperate ecoregions in North America. The objective of this research was to examine how deeproot sedge responds to prescribed fire, to the herbicide imazapic, and to treatment combinations of both. Combinations of prescribed fire and imazapic treatments and imazapic-only treatments effectively reduced deeproot sedge cover and frequency. However, plots exposed to dormant season fires (with no imazapic) had greater deeproot sedge cover after burn treatments were applied, indicating that coastal prairie management using only dormant season prescribed fire will not work toward reduction or management of this exotic invasive species. Although deeproot sedge cover was often reduced in fire–imazapic treatment combinations, it was still present in treatment plots. Moreover, desirable functional plant groups (i.e., native bunchgrasses) did not respond positively to the fire–imazapic treatments, but in some instances, woody plant coverage increased. Repeated, long-term approaches using integrated and coordinated efforts with multiple treatment options will be necessary to restore community structure to desired compositional levels. Such integrated approaches should be effective in reducing deeproot sedge frequency, cover, and extent to more manageable levels throughout its introduced geographic range.

AbstractNonnative invasive plants (NNIP) have far-reaching effects on native ecosystems worldwide. Understanding the role of generalist seed dispersers in spreading NNIP across the landscape is important to the conservation of native ecosystems and to the management of NNIP. We studied white-tailed deer (Odocoileus virginianus) as a seed disperser in a mixed maritime pine (Pinusspp.) forests on Parris Island, SC, with particular interest in the dispersal of Chinese tallowtree [Triadica sebifera(L.) Small], a highly invasive tree species in the southeastern United States, which is a management concern on Parris Island, SC. We collected deer scat pellet groups along transects in two forest types: those that had recently been treated with silvicultural timber harvest (thinned) and those that have not been so treated (unthinned). Using two pellet-treatment methods, directly planting or rinsing and sorting, we determined that, out of 25 species grown under greenhouse conditions, 28% (n= 7) were nonnative, small-seeded, herbaceous species. However,T. sebiferawas not identified in either of the two treatment methods. Recent forest thinning significantly affected the number of species determined in deer pellet groups (F= 8.37; df = 1; P < 0.01), with more native plant species identified in unthinned (x̄= 25 ± 11) than in thinned (x̄= 3 ± 10) forest stands (F= 5.33; df = 1; P = 0.02). Our results indicate that white-tailed deer are actively dispersing nonnative seeds but not those ofT. sebiferaor other woody NNIP.

AbstractOn August 5, 2013, a marketing authorization valid throughout the European Union (EU) was issued for pomalidomide in combination with dexamethasone for the treatment of adult patients with relapsed and refractory multiple myeloma (MM) who have received at least two prior treatment regimens, including both lenalidomide and bortezomib, and have demonstrated disease progression on the last therapy. Pomalidomide is an immunomodulating agent. The recommended starting dose of pomalidomide is 4 mg once daily taken on days 1–21 of repeated 28-day cycles. The main evidence of efficacy for pomalidomide in MM was based on a phase III multicenter, randomized, open-label study (CC-4047-MM-003) in which pomalidomide plus low-dose dexamethasone therapy (POM+LoDEX) was compared with high-dose dexamethasone alone (HiDEX) in previously treated adult patients with relapsed and refractory multiple myeloma who had received at least two prior treatment regimens, including both lenalidomide and bortezomib, and had demonstrated disease progression on the last therapy. For the intent-to-treat population, median progression-free survival based on International Myeloma Working Group criteria was 15.7 weeks (95% confidence interval [CI]: 13.0–20.1) in the POM+LoDEX group versus 8.0 weeks (95% CI: 7.0–9.0) in the HiDEX group (log-rank p value &lt;.001). Overall survival (secondary endpoint) was also different in the two treatment groups (hazard ratio 0.53 [95% CI: 0.37–0.74]). The most commonly reported adverse reactions to pomalidomide in clinical studies were anemia (45.7%), neutropenia (45.3%) and thrombocytopenia (27%), fatigue (28.3%), pyrexia (21%), peripheral edema (13%), and infections including pneumonia (10.7%). Peripheral neuropathy adverse reactions were reported in 12.3% of patients, and venous embolic or thrombotic (VTE) adverse reactions were reported in 3.3% of patients. Pomalidomide is expected to be teratogenic. This paper summarizes the scientific review of the application leading to approval in the EU. The detailed scientific assessment report and product information, including the summary of product characteristics, are available on the EMA website (http://www.ema.europa.eu).

Published: February 2015

En los bosques mesófilos de montaña, los disturbios antropogénicos afectan la abundancia y diversidad de las comunidades de epífitas; sin embargo, las causas de estos cambios han sido poco exploradas. En este trabajo se evalúa la variación del área foliar, grosor de la lámina foliar, masa seca por unidad de área, densidad foliar y contenido de humedad en las diez especies de epífitas vasculares más abundantes de bosque mesófilo y vegetación derivada (bosque conservado, acahual de 20 años y cafetal bajo sombra), ubicado en la región central de Veracruz, México. El propósito del estudio fue entender de qué manera la variación mircroambiental (temperatura, humedad relativa y radiación fotosintéticamente activa), determinada por la apertura del dosel que provocan las actividades antrópicas, influye en las características funcionales de las epífitas. Las condiciones de mayor estrés hídrico y mayor radiación se registraron en la comunidad más modificada y con mayor apertura del dosel (cafetal), y disminuyeron conforme se incrementa el grado de conservación y el dosel es más cerrado (acahual-bosque). Estos cambios microambientales se asociaron con las respuestas funcionales de las especies estudiadas. En el bosque conservado, las epífitas presentaron significativamente hojas más delgadas, con mayor contenido de humedad, menor masa seca y densidad foliar; mientras que en el cafetal se encontró el patrón opuesto. Las características funcionales de las comunidades de epífitas fueron útiles para determinar el estado de conservación en el bosque mesófilo y, permitieron entender que factores microambientales determinan sus respuestas funcionales.

Published: February 2015

Background: Aromatase inhibitor (AI) use results in low estrogen levels, which in turn affect bone mineral density (BMD). Periodontitis, alveolar bone loss, and tooth loss are associated with low BMD. The goal of this study is to assess the prevalence of periodontitis and perceived oral health and evaluate salivary biomarkers in postmenopausal women who are survivors of early‐stage (I to IIIA) breast cancer (BCa) and receive adjuvant AI therapy.Methods: Participants included 58 postmenopausal women: 29 with BCa on AIs and 29 controls without BCa diagnoses. Baseline periodontal status was assessed with: 1) periodontal probing depth (PD); 2) bleeding on probing (BOP); and 3) attachment loss (AL). Demographic and dental utilization information was gathered by questionnaire. Linear regression modeling was used to analyze the outcomes.Results: No differences were found in mean PD or number of teeth. The AI group had significantly more sites with BOP (27.8 versus 16.7; P = 0.02), higher worst‐site AL (5.2 versus 4.0 mm; P <0.01), and more sites with dental calculus (18.2 versus 6.4; P <0.001) than controls. Linear regression adjusted for income, tobacco use, dental insurance, and previous radiation and chemotherapy exposure demonstrated that AI use increased AL by >2 mm (95% confidence interval, 0.46 to 3.92). Median salivary osteocalcin and tumor necrosis factor‐α levels were significantly higher in the AI group than the control group.Conclusion: This first investigation of the periodontal status of women initiating adjuvant AI therapy identifies this population as having an increased risk for periodontitis.

Case:
We present two cases of anterior glenohumeral instability in which both the humeral head and the glenoid were reconstructed concurrently with use of allografts; we discuss the midterm outcomes at four and one-half and five years of follow-up, respectively.

Conclusion:
In our experience, concomitant glenoid and humeral head allograft reconstruction for anterior glenohumeral instability with severe combined humeral head and glenoid pathology yielded good midterm clinical, functional, and radiographic outcomes. This treatment approach may be a viable option for young and active patients presenting with severe combined glenoid and humeral pathology and warrants additional investigation.
Battle for Oil Market Control Could Have a Lasting Impact
Authors: Rassenfoss Stephen , Betz Jack

Global Oil Prices - Low Oil Prices and Stiff Competition Causes of Anxiety for Graduates
Expectations of continued USD 100/bbl of oil were shattered by a sharp price drop last year that eventually halved the prices of benchmark crudes. Prices were still sinking at the start of the year to lows not seen since 2009 due to a global oversupply of oil.
The US has gone from the world’s best import market for oil to a market moving producer, and a large and growing exporter of refined products. Total US output rose from 5 million B/D in 2008 to 9.2 million B/D in December, according to the US Energy Information Administration (EIA), which predicts 9.3 million B/D by the end of this year.
While the magnitude of the drop rivals the one in 2009, the cause of it resembles the longer-lasting downturn that began in the 1980s, after a run of high prices rapidly expanded oil supplies, creating a glut.
The rise of oil flowing from US shale formations has sparked a battle for control of the market with OPEC, which has been unwilling to reduce its production to prop up prices because that would further erode its share of a market where production outside OPEC rose by 2 million B/D in 2014, according to the EIA, which said demand was up by 900,000 B/D.
OPEC’s goal is to ultimately reduce production by forcing output reductions by what Saudi Arabian Minister of Petroleum and Mineral Resources Ali al-Naimi has described as “inefficient producers.”
The strategy, which allowed the price of a barrel of oil to drop to less than USD 50 early this year, appears aimed at the independent companies producing millions of barrels a day from tight, unconventional formations, where the cost of extracting oil is far more expensive than Saudi Arabia’s world-class reservoirs.
So far the news suggests this could be a slow-moving process. The large, public US producers have announced significant reductions in planned exploration and production (E&P) budgets, but still predict greater production in the year ahead.
Industry Needs Re-Education in Uncertainty Assessment
Authors: McVay Duane 
Published: February 2015

Management
It is clear the oil and gas industry recognizes the large uncertainty in which it operates. A search in the OnePetro technical paper database using the keywords “uncertainty” or “risk” returns more than 53,000 conference and journal papers. Yet, it is also clear that the industry does not know how to reliably assess uncertainty and that this inability negatively affects industry performance. Capen (1976) described the difficulty of assessing uncertainty. He pointed to massive capital overruns and low industry returns due to an almost universal tendency to underestimate uncertainty. Brashear et al. (2001) and Rose (2004) later documented the dismal performance of the industry in the last 10 to 20 years of the 20th century due to chronic bias and evaluation methods that do not account for the full uncertainty.
Although industry profitability may have improved in the past decade because of high oil prices, Neeraj Nandurdikar in an October 2014 JPT article, “Wanted: A New Type of Business Leader to Fix E&P Asset Developments,” showed that the oil and gas industry continues to perform significantly below estimations and expectations. He cited three ways that assets erode value, all of which relate to unreliable assessments of uncertainty: (1) production and reserves estimates are overestimated, (2) capital costs are underestimated, and (3) development times are underestimated. And these do not include price estimations; the surprising oil price slide at the time of this writing has the potential to move industry performance from below expectations to below profitability.
While project evaluations can be affected by many different types of biases, these can be reduced fundamentally to two primary biases: overconfidence and directional bias.
Overconfidence is underestimation of uncertainty; i.e., our estimated distributions of uncertain quantities, such as reserves, are too narrow. They are too narrow because we do not consider all the possible outcomes. There is considerable evidence in the literature, both inside and outside the petroleum industry, of our general human tendency for overconfidence.
Directional bias results when the subset of possible outcomes considered is shifted in either the optimistic or pessimistic direction. There is also evidence that we are usually optimistic in our overconfidence; i.e., we fail to consider some possible negative outcomes, or we give greater weight to possible positive outcomes than possible negative outcomes. As a result of the two primary biases, we make decisions with incorrect estimated distributions rather than true distributions (Fig. 1).
