Comparative Bioremediation of Crude Oil-Amended Tropical Soil Microcosms by Natural Attenuation, Bioaugmentation, or Bioenrichment
Vanessa Marques Alvarez,Joana Montezano Marques,Elisa Korenblum,Lucy Seldin
Applied and Environmental Soil Science , 2011, DOI: 10.1155/2011/156320
Abstract: Bioremediation is an efficient strategy for cleaning up sites contaminated with organic pollutants. In this study, we evaluated the effectiveness of monitored natural attenuation, bioenrichment, and bioaugmentation using a consortium of three actinomycetes strains in remediating two distinct typical Brazilian soils from the Atlantic Forest and Cerrado biomes that were contaminated with crude oil, with or without the addition of NaCl. Microcosms were used to simulate bioremediation treatments over a 120-day period. During this period, we monitored total petroleum hydrocarbons (TPHs) and n-alkanes degradation and changes in bacterial communities. Over time, we found the degradation rate of n-alkanes was higher than TPH in both soils, independent of the treatment used. In fact, our data show that the total bacterial community in the soils was mainly affected by the experimental period of time, while the type of bioremediation treatment used was the main factor influencing the actinomycetes populations in both soils. Based on these data, we conclude that monitored natural attenuation is the best strategy for remediation of the two tropical soils studied, with or without salt addition. 1. Introduction The high demand for and use of petroleum and its derivatives worldwide has made petroleum hydrocarbon contamination a global problem with serious health and environmental consequences [1–3]. Contamination of soil and groundwater with petroleum compounds is frequently observed, necessitating the development of innovative technologies for remediation [4, 5]. Bioremediation is an efficient and environmentally friendly technology for long-term restoration of sites contaminated with petroleum hydrocarbons and derivatives [5, 6]. Several studies have focused on the composition of naturally occurring microbial populations that contribute to biodegradation of petroleum and its derivatives in different environments [7–10]. Monitored natural attenuation (MNA) uses the ability of the soil intrinsic microbial community to degrade the contaminant. In cases where enhancement of the soil microbial community is deemed necessary, either bioaugmentation or bioenrichment is used. Bioaugmentation relies upon pollutant-degrading microorganisms found in the contaminated site, whereas in bioenrichment the microorganisms are exogenous [11, 12]. Regardless, studies of both approaches have demonstrated that the degrading organisms are not maintained in the contaminated environment after introduction [13, 14]. Therefore, molecular methods that rapidly survey the microbial community
Memories of an Autopsy: The Effects of Stress Exposure on Suggestibility for a Stressful Event
Elisa Krackow,Vanessa M. Jacoby,Joseph R. Scotti
International Journal of Psychological Studies , 2013, DOI: 10.5539/ijps.v5n1p69
Abstract: The current study examined the effects of stressful life events on memory for a stressful event. Two groups of college students (N = 61) were formed for analysis based on the presence or absence of particular stressful life events. Participants then viewed a graphic video depicting an autopsy, and received a memory interview four days later. Results showed similar group performance on correctly leading questions. However, participants in the Specific Stressor-Exposed group were less suggestible to misleading questions than their Specific Stressor-Absent counterparts. Results are discussed in terms of stress sensitization theory and cognitive processing models.

Behavioral and Experiential Self-Regulations in Psychological Well-Being under Proximal and Distal Goal Conditions  [PDF]
Peter Horvath, Vanessa McColl
Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.412141
Abstract:

This study examined the relationship of goal-related components of cybernetic, behavioral, and experiential self-regulations to psychological well-being under two types of conditions, the pursuit of intrinsic goals in general and specific intrinsic goals for the academic term. In an online survey, undergraduates (N = 186) completed global measures of psychological well-being, behavioral and experiential self-regulations, and rated themselves on goal-related self-regulatory components. Correlations indicated that most of the cybernetic, behavioral and experiential self-regulatory variables were associated with each other and with well-being. In terms of the goal-related self-regulatory components, when pursuing intrinsic goals more generally, the experiential self-regulatory component of enjoyment of the activity predicted well-being. However, when pursuing intrinsic term goals, the cybernetic self-regulatory component of perceived goal progress and the behavioral self-regulatory component of self-reinforcement for goal progress predicted well-being. The findings extend theoretical conceptualizations of psychological well-being by integrating compatibilities between cybernetic, behavioral, experiential self-regulatory processes and motivational conditions.

Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.32023
Abstract: This paper analyses human mobility control in Sicily, linking it with immigrants’ employment segregation. The focus is on the Cara of Mineo that, since 2011, has represented one of the most important “laboratory” in order to observe the effects of Italian migration governance. The study is supported by several interviews to stakeholders and to migrant farm hands. The first aim is to show how a place designed to contain the mobility of people [1] can be seen as area where the migration movements are intersected with the economic needs of local context.
