Authors: Baidog Adriana , Popa Amorin-Remus
Published: April 2019

Introduction: The Metabolic Syndrome is considered at present as one of the most important causes of mortality and morbidity at world level. Even if the uric acid is not part of any definition of the Metabolic Syndrome, the actual studies have shown strong associations between uric acid concentration and the Metabolic Syndrome or its components, the role of Uric Acid within the Metabolic Syndrome (MS) being increasingly investigated.

Aims: We have analyzed recently published data that show the importance of hyperuricemia in MS, Cardiovascular Diseases, Chronic Kidney Disease.

Conclusions: Uric Acid (UA) is a central player in MS progression and in cardiorenal pathology, which is why a multidisciplinary approach and a correct treatment are required, in order to obtain multiple benefits and, possibly, in the future, new therapeutic guidelines in approaching MS.

Las actitudes o intenciones frente al problema ambiental derivado del consumo no siempre son consistentes con los hábitos o comportamientos pro ambientales. En este trabajo se estima la relación causal entre las ac- titudes, las barreras y los hábitos de las personas que consumen productos empacados en plásticos (PET) en la ciudad de Medellín. Se estimaron modelos de regresión de Poisson y modelos de ecuaciones estructurales con base en la información capturada a una muestra de 300 consumidores. Dentro de los resultados se observa un comportamiento que evidencia falta de conciencia ambientalista, ya que se aumenta el consumo de envases plásticos en quienes afirman que la contaminación no afecta su vida personal. Por otro lado, a quienes les preocupa la contaminación, la elección de productos se condiciona por la diferencia en el precio. También, se evidencia desconocimiento de los encuestados sobre el tipo de envase más amigable con el medio ambiente.

Intrinsic doping limit and defect-assisted luminescence in Cs4PbBr6
Authors: Jung Young-Kwang , Calbo Joaquin , Park Ji-Sang , Whalley Lucy D. , Kim Sunghyun , Walsh Aron
Published: April 2019

Cs4PbBr6 is a member of the halide perovskite family that is built from isolated (zero-dimensional) PbBr64- octahedra with Cs+ counter ions. The material exhibits anomalous optoelectronic properties: optical absorption and weak emission in the deep ultraviolet (310 - 375 nm) with efficient luminescence in the green region (~ 540 nm). Several hypotheses have been proposed to explain the giant Stokes shift including: (i) phase impurities; (ii) self-trapped exciton; (iii) defect emission. We explore, using first-principles theory and self-consistent Fermi level analysis, the unusual defect chemistry and physics of Cs4PbBr6. We find a heavily compensated system where the room-temperature carrier concentrations (< 109 cm-3) are more than one million times lower than the defect concentrations. We show that the low-energy Br-on-Cs antisite results in the formation of a polybromide (Br3) species that can exist in a range of charge states. We further demonstrate from excited-state calculations that tribromide moieties are photoresponsive and can contribute to the observed green luminescence. Photoactivity of polyhalide molecules is expected to be present in other halide perovskite-related compounds where they can influence light absorption and emission.

Published: April 2019

Compounds from the 2,2’-bipyridine molecular family were investigated for use as redox-active materials in organic flow batteries. For 156 2,2’-bipyridine derivatives reported in the academic literature, we calculated the redox potential, the pKa for the first protonation reaction, and the solubility in aqueous solutions. Using experimental data on a small subset of derivatives, we were able to calibrate our calculations. We find that functionalization with electron-withdrawing groups leads to an increase of the redox potential and to an increase of the molecular acidity (as expressed in a reduction of the pKa value for the first protonation step). Furthermore, calculations of solubility in water indicate that some of the studied derivatives have adequate solubility for flow battery applications. Based on an analysis of the physico-chemical properties of the 156 studied compounds, we down-select five molecules with carbonyl- and nitro-based functional groups, whose parameters are especially promising for potential application as negative redox-active material inorganic flow batteries.
Indirect Detection of Short-lived Hydride Intermediates of Iridium N-Heterocyclic Carbene Complexes via Chemical Exchange Saturation Transfer (CEST) Spectroscopy
Authors: Knecht, Stephan , Hadjiali Sara , Barskiy Danila , Pines Alexander , Sauer Grit , Kiryutin Alexey S , Ivanov Konstantin , Yurkovskaya Alexandra V. , Buntkowsky Gerd
Published: April 2019

For the first time chemical-exchange saturation transfer (CEST) 1H NMR is utilized for the study of short-lived hydride intermediates in the catalytic cycle of the Iridium-based organometallic complex [Ir(IMes)(Py)3(H)2]Cl, which are often not observable by other NMR techniques, since they are low concentrated, and undergo reversible ligand exchange with the main complex. The intermediate complexes [Ir(Cl)(IMes)(Py)2(H)2] and [Ir(CD3OD)(IMes) (Py)2(H)2] are detected, assigned and characterized in situ and at room temperature in solution. Understanding the effects on the spin dynamics induced by these complexes is necessary for enhancing the performance of the nuclear spin hyperpolarization technique SABRE (Signal Amplification By Reversible Exchange). By eliminating [Ir(Cl)(IMes)(Py)2(H)2] and manipulating the spin-system by RF-irradiation, we were able to increase the nuclear spin singlet lifetime of the two protons in the main hydride complex by more than an order of magnitude, from 2.2±0.1 s to 27.2±1.2 s. The presented CEST NMR approach has a large application potential for studying short-lived hydride intermediates in catalytic reactions.
Low-Order Many-Body Interactions Determine the Local Structure of Liquid Water
Authors: Riera Marc , Lambros Eleftherios , Nguyen Thuong T. , Goetz Andreas W. , Lab Paesani
Published: April 2019

Despite its apparent simplicity, water displays unique behavior across the phase diagram which is strictly related to the ability of the water molecules to form dense, yet dynamic, hydrogen- bond networks that continually fluctuate in time and space. The competition between different local hydrogen-bonding environments has been hypothesized as a possible origin of the anomalous properties of liquid water. Through a systematic application of the many-body expansion of the total energy, we demonstrate that the local structure of liquid water at room temperature is determined by a delicate balance between two-body and three-body energies, which is further modulated by higher-order many-body effects. Besides providing fundamental insights into the structure of liquid water, this analysis also emphasizes that a correct representation of two-body and three-body energies requires sub-chemical accuracy that is nowadays only achieved by many-body models rigorously derived from the many-body expansion of the total energy, which thus hold great promise for shedding light on the molecular origin of the anomalous behavior of liquid water.
A New Interpretation of the Structure and Solvent Dependence of the Far UV Circular Dichroism Spectrum of Short Oligopeptides
Authors: Kumar Anshuman , Schweitzer-Stenner Reinhard , Wong Bryan
Published: April 2019

In this work, we carry out new time-dependent density functional theory calculations on the cationic tripeptide GAG in implicit and explicit water to determine the transitions that give rise to the observed CD signals of polyproline II and β-strand conformations. Our results reveal a plethora of electronic transitions that are governed by configurational interactions between multiple molecular orbital transitions of comparable energy. We also show that reproducing the CD spectra of polyproline II and β-strand conformations requires the explicit consideration of water molecules. The structure dependence of delocalized occupied orbitals contributes to the experimentally-observed invalidation of Flory’s isolated pair hypothesis.

A EDUCAÇÃO ESPECIAL INCLUSIVA A PARTIR DA DEFECTOLOGIA DE VYGOTSKI
Authors: Façanha Luciano Da Silva , Fahd Wilma Cristina Bernardo
Published: April 2019

Este artigo objetiva analisar os conceitos de Vygotski sobre Defectologia que podem ser considerados como precursores para compreensão de uma proposta de Educação Especial inclusiva. A sustentação das concepções e práticas de Educação Especial demanda um embasamento científico para o paradigma da inclusão. Assim, distinguimos a atualidade das ideias de Vygotski em seus questionamentos a respeito das explicações reducionistas e negativas sobre a deficiência. Trata-se de um estudo bibliográfico, e o fenômeno investigado foi situado através do aporte teórico da obra Fundamentos da Defectología,de autoria do próprio Vygotski e das produções científicas de autores que comentam sua obra: Beyer (2005), Barroco (2007), Newman e Holzman (2002), Oliveira (2011), Rego, (2011), Valsiner e Van Der Veer (1996), Delari Junior (2013). Os resultados obtidos evidenciaram a partir dos conceitos vygotskianos relativos ao desenvolvimento e aprendizagem das pessoas com deficiências, que o autor postulou a prática de uma Educação Especial não segregada, unificada à educação regular, para permitir a convivência plena dos alunos com deficiências na escola comum em consonância com o pressuposto da sociogênese das funções superiores humanas.

POR QUE OCUPAR? RESISTÊNCIA, CONTRACONDUTA E PROTAGONISMO ESTUDANTIL
Authors: Ferraro José Luís Schifino
Published: April 2019

O presente ensaio tem como objetivo discutir o movimento de ocupações de escolas da rede pública do Brasil ocorridos no final do ano de 2015 e no início do ano de 2016 à luz da filosofia de Michel Foucault. Ao tomar como referências reportagens de jornais que acompanharam o dia a dia das ocupações - para contextualização do cenário - e da obra de Foucault para analisar tais ações protagonizadas pelos estudantes, pretendeu-se identificar elementos apontados pelo filósofo francês como importantes para o debate em torno da temática da governamentalidade. Resistência e contraconduta são dois conceitos que serão observados e discutidos ao longo desse trabalho em uma tentativa de legitimar o direito que alunos e professores têm em reivindicar uma educação pública de qualidade.

Clusia minor L. is traditionally used to treat many disorders that including pain and inflammation such as sores and warts. Four extracts from the leaves of plant were prepared: hexane (CMH-A), ethyl acetate (CMH-B), methanol (CMH-C) and ethanol (CMH-E) and the pharmacological (antioxidant and anti-inflammatory properties) and toxicity effects were examined. Previously, the main constituents from CMH-A extract was revealed. Here, we present the GC/MS analysis of CMH-B and CMH-C. Thirty three compounds were identified in the CMH-B extract and twenty seven compounds in the CMH-C. The presence of D-α-tocopherol and lupeol was relevant in both extracts. The only sterols identified were sitosterol and stigmasterol. All of them showed effective radical scavenger properties in the 1,1-diphenyl-2-picryl-hydrazyl (DPPH) assay, being CMH-E extract the most promissory (IC50 = 10.25 µg/mL). CMH-A, C and E extracts, administered topically (0.5–4 mg per ear), significant reduced ear edema induced by croton oil at 4 mg per ear, meanwhile CMH-B that was be able to significant reduce the inflammation at the dose of 2 mg per ear. We evaluated also the cytotoxic activity of the extracts against kidney cells (BHK), colon cancer (CT26), endothelial cancer cells (EA.hy926) and breast cancer (4T1). CMH-B extract showed the most cytotoxicity effect, with IC50 values in the range of 32.01-203.5 µg/mL. In addition, no oral acute toxicity after mice exposure to Clusia minor L. extracts was observed. The results suggest Clusia minor L. may be a good potential source of new bioactive agents for developing medicinal agents.

Published: April 2019

The glycerol, D-glucose monohydrate (DGMH), sucrose, and sodium chloride are used in food industries and the measurement of properties for these components and their aqueous solutions can be important. In this research work, the refractive indices for binary solutions of (methanol + glycerol), (ethanol + glycerol), ternary solutions of (water + glycerol + DGMH), (water + glycerol + sucrose), (water + sucrose + DGMH), (water + sucrose + ethanol), (water + ethanol + DGMH), (water + NaCl + DGMH), (water + methanol + NaCl), (water + ethanol + NaCl), (water + NaCl + glycerol), (water + sucrose + NaCl), and quaternary solutions of (water + ethanol + sucrose + DGMH), (water + ethanol + sucrose + glycerol), (water + NaCl + sucrose + glycerol) were measured in wide range of mole fractions at T = 293.15 K and atmospheric pressure. For binary solutions of this study, the changes of refractive index on mixing, ∆nD, were calculated in each mole fraction at T = 293.15 K. Also, the refractive index of binary solutions was fitted by a semi-empirical equation. The constant of this equation, Kr, was represented by Koohyar et al. in 2011. This constant can be used to investigate power of interactions between solute and solvent molecules. For ternary and quaternary solutions of this study, a semi-empirical equation was used to determine refractive indices at given temperature. The comparison between calculated and experimental refractive indices shows that there is a good agreement between them especially in lower molal concentrations.
La “contradicción fundamental” en el movimiento critical legal studies
Authors: Flórez Sandoval Leidy Lizeth
Published: April 2019

Como heredero del realismo jurídico estadounidense de principios del siglo XX, el movimiento Critical Legal Studies –en adelante CLSenarbola la bandera de la indeterminación del Derecho. Sin embargo, va más allá de la tesis realista y sostiene que tal no obedece a un mero problema lingüístico o formal sino a una verdadera manifestación de una “contradicción” o una serie de contradicciones sustantivas que subyacen al liberalismo, entendido como tradición ideológica, económica y política sobre la que se ha construido el modo de vida estadounidense.

El objeto de este trabajo es describir en qué consiste esta “contradicción”  desde la perspectiva de los miembros de CLS, así como de los autores que, tanto en Europa como en América Latina, la han analizado –si así ha sido- . Para lograrlo será menester previamente: i) trazar un esquema general que permita comprender, a grandes rasgos, lo que CLS es y defende; ii) abordar los trabajos “paradigmáticos” al interior del movimiento CLS sobre la contradicción, particularmente los producidos por Duncan Kennedy; iii) revisar si en la literatura europea y latinoamericana esta idea ha tenido repercusión y, de ser así, cómo se ha efectuado su análisis.

The Provision of Public Pre-K in the Absence of Centralized School Management
Authors: Weixler Lindsay Bell , Lincove Jane Arnold , Gerry Alica
Published: April 2019

Using administrative and qualitative data, we investigate how decentralization affects the supply of optional educational services using the example of school-based prekindergarten (pre-K) in New Orleans during the transition to a majority-charter system. Although charter school leaders are motivated by student- and school-level benefits of pre-K, they face unique obstacles to funding classrooms. We find that the number of pre-K seats fell substantially as decision making and budgeting were decentralized. Charter schools that did offer pre-K experienced few internal benefits, on average, in terms of future enrollment or test performance, as pre-K graduates are highly mobile. This study provides initial evidence that decentralization without offsetting financial incentives can lead to reduced investments in programs that advance the social goals of education.

Gendered Pathways to Bullying via Social Achievement Goals – Mediating Effects of Sense of Belonging and Non-inclusive Group Norms
Authors: Bardach Lisa , Graf Daniel , Yanagida Takuya , Kollmayer Marlene , Lüftenegger Marko
Published: April 2019

This study investigated the gender-specific effects of social achievement goals - i.e., social development goals, social demonstration approach goals, and social demonstration avoid goals - on bullying perpetration in a sample of 788 adolescents (53.3% girls), taking into account the mediating role of sense of belonging and non-inclusive group norms. Two-group structural equation modeling results indicated that social demonstration approach goals positively predicted bullying perpetration for both genders. For girls, higher social development goals and for boys, higher social avoidance goals decreased bullying perpetration. Gender-specific effects of belonging and non-inclusive group norms on bullying perpetration occurred. For boys, non-inclusive group norms mediated the relation between all social achievement goals and bullying perpetration. Implications for future research and (gender- sensitive) bullying interventions are discussed.

Authors: Int Chem
Published: April 2019

The objective of present research was to characterize the surface soils located at 300, 600 and 1000 m of an uncontrolled landfill. The work also aims to evaluate the levels and spatial distribution of metallic trace elements (Cd, Pb, Cu, Ni, Zn, Cr, Co and As) in these soils. Soil samples were collected in 36 points around the landfill. Results showed that Cd, Pb, Zn are concentrated in the soils rich in clay and carbonates, and in organic matter, located at 300 m from the landfill. The basic pH of all soils enhances the retention of these metals. On the other hand, As present in soils at 300, 600 and 1000 m at concentrations slightly higher than those of referenced soils were apparently mobilized by water from the solid/water interfaces. The other metals Cu, Ni, Co, Cr are present at very low concentrations.

The aim of this study was to screen the phytochemical constituents, isolate and elucidate the structure of chloroform extracts from the leaves of Maesa lanceolata. The qualitative phytochemical analysis of the leaf extract of Maesa lanceolata was done following standard procedures and the tests revealed the presence of cardiac glycosides and saponins in the crude extracts. The chloroform extract of the leaves of M. lanceolata led to the isolation of one compound, C1. Structure determination was accomplished by means of spectroscopic methods (IR, 13C and 1H NMR). According to the spectral data (IR, 1HNMR, 13CNMR and DEPT), probably Myrsenene was identified which is reported for the first time from M. lanceolata.
Study of the vibronic coupling in the ground state of Methylthio radical
Authors: Int Chem
Published: April 2019

Using a methodology based on the crude adiabatic approximation, we study the complete linear and quadratic vibronic coupling in the ground state of SCH3 radical. In order to build the representation of the hamiltonian, we evaluated 30 integrals intervening in the formulation of the vibronic coupling. Diagonalization of this representation gives the vibronic levels. For the lowest vibronic states, the implied modes are Q1 (symmetric C-S stretching) and Q4 (CH3 rocking). Energy gaps A1-A2 and A2-ε resulting from the splitting due to the Jahn-Teller coupling E e = A1 + A2+ ε are evaluated to 250 and 169 cm-1, respectively. Essential coupling parameters are surrounded to simplify the study of highly vibronic states.
Chemical precipitation method for chromium removal and its recovery from tannery wastewater in Ethiopia
Authors: Int Chem
Published: April 2019

Most of the tanneries in Ethiopia (90%) do not treat and very few (10%) partially treat their effluent before discharging it into the receiving water bodies. The untreated tannery effluent causes tremendous pollution of water resources in the country, especially due to its high organic loading and chromium content. Chromium(III) salts are the most widely used chemicals for tanning processes, but only about 60-70% of total chromium salts reacts with the hides and about 30-40% of the chromium remain in the solids and liquid wastes (especially spent tanning solutions). Therefore, the removal and recovery of the chromium content of these wastewaters is necessary for environmental protection and economic reasons. The purpose of this study was to develop an alternative process for removing and recovering trivalent chromium from tannery wastewater via chemical precipitation with sodium hydroxide (NaOH), calcium hydroxide (Ca(OH)2) and magnesium oxide (MgO). The effects of pH, stirring time, settling rate and sludge volume were studied in batch experiments. Flame atomic absorption spectrometry was used to determine Cr concentration. The results showed that removal efficiencies of the precipitating agents NaOH (99.97%), Ca(OH)2 (99.97%) and MgO (99.98%) at optimum pH values were not significantly different. However, there was a significant difference in sludge volume of NaOH (590 mL), Ca(OH)2 (412 mL) and MgO (85 mL). The optimum pH of 9.8-10.3 with removal efficiency of 99.98% and the good sludge with high settling rate and lower volume was obtained using MgO precipitating agent. Hence the MgO was found to be a good precipitating agent for removal and recovery of chromium from tanning wastewater. The basic chromium sulfate (BCS) recovered at pH 2.8 is suitable for tanning mixed with fresh BCS from the market.

Authors: Rauf Rosnita ita
Published: April 2019

The group in the Kerinci Seblat National Park area is the main watershed, namely the Batanghari watershed, Musi watershed and the western coastal watershed, the watershed is vital to fulfilling the water needs of the lives and lives of millions of people living in the area . The potential of existing water in the forest area can be used to drive the electricity generation system. Existing water potential is one of the primary energy that can be used as renewable energy. Electric energy is already a primary need for modern Indonesian society today. This situation is characterized by the community's dependence on electrical energy in carrying out activities of daily life, both at home, at the office, in hotels and in industrial processes, all of which rely heavily on electrical energy.Indonesia is blessed with primary energy resources thar are very potential to build new and renewable energy-based power plants such us nuclear, geothermal power, hydropower, niomass, wind power, solar power and ocean wave energythat have notbeen optimall utilized.Consideration of energy conservation and the environment require us to immediately be able to ultilize renewable energy – which is easily available and more environmentallt friendly than fossil energy.Alternative energy development is absolutely necessary, therefore it is necessary to survey river potential, especially in the Kerinci Sebelat National Park area (TNKS) to meet the electricity needs of the community. With the availability of these water resources, it can be developed into a Micro Power Plant or Mini Hydro.The purpose of this primary energy utilization is to reduce our dependence on fossil fuel energy use whose availability is starting to worry. Several alternative energy sources that are abundant in Indonesia can be utilized without having to substitute the existing conventional energy values. It is hoped that through the use of new and renewable energy can slowly reduce the priority of using fossil fuel-based energy to further replace its role as a counterweight. The use of conventional energy continues to be used, not diverted and even eliminated, but slowly led to changes in the priority scale of its supply needs in remote areas. The time for modern/big cities to change the paradigm to make new and renewabable energy a new “lifestyle”, given that for the sake of the environment in its role to reduce CO2 esmissions.
A Meta-Analysis of Implicit and Explicit Attitudes in Children and Adolescents
Authors: Phipps Daniel John , Hagger Martin S , Hamilton Kyra
Published: April 2019

We present a meta-analytic review of studies measuring implicit and explicit attitudes in child and adolescent samples. A meta-analytic structural equation model revealed that both implicit and explicit attitudes independently predicted behavior, with a larger effect size for explicit attitudes. Moderator analyses revealed larger effects of implicit measures on behavior for social bias behaviors compared to diet and health-related behaviors and aggression behaviors. Age did not moderate the size and relative contribution of both forms of attitude on behavior, and the implicit-explicit attitude correlation. Studies adopting a fixed order of attitude measure presentation, rather than counterbalanced, and those using the implicit association test to measure implicit attitudes exhibited stronger implicit attitude-behavior effects than those adopting other measures. Findings support an additive model for the effects of implicit and explicit attitudes on behavior in children and adolescents, and provide formative evidence to guide future research using implicit measures in younger populations.
Development of a Selective Extinction through Cognitive Evaluation Paradigm
Authors: Macdonald Birthe , Johnstone Tom
Published: April 2019

In this study we trialled a novel paradigm that aims to bridge the gap between the research into the extinction of conditioned responses and the instructed regulation of emotion via a prescribed strategy. This was done through a process we called Selective Extinction through Cognitive Evaluation (SECE). Participants were conditioned to associate a previously neutral stimulus (letter, CS+) with an aversive burst of white noise (US) and another letter with no aversive event (CS-). In a second phase, the same letters were presented within words belonging to two distinct categories. One group did not receive any more noise bursts during this phase which lead to the extinction of the conditioned responses (extinction group). The other group (SECE group) was told that the CS+ now only carried a risk of the noise occurring when it was presented in one (dangerous), but not the other word category (safe). Affective responses were assessed using skin conductance responses (SCR). We found overall increased SCR’s in response to CS+ (safe and dangerous) compared to CS- trials in the SECE group, and also increased SCR’s in response to dangerous compared to safe CS+ trials. This suggests that the conditioned response (CR) can be reduced through the cognitive evaluation of additional information and it is possible that extinction mechanisms are involved in this process. We did not find any effects in the extinction group. It is possible that extinction was completed too quickly so that any differences between conditions could not be captured. We therefore conducted a second study to pilot an improved paradigm. We visually amended the trials, amended the reinforcement schedule, and changed to a fully within-subjects design. Here we once again found significantly reduced SCR to safe compared to dangerous CS+ trials. Future experiments will use these results as a basis for an improved paradigm to better capture changes in SCR as well as BOLD fMRI in future experiments.

Authors: Kleine Anne-Kathrin , Rudolph Cort , Zacher Hannes
Published: April 2019

Thriving at work refers to a positive psychological state characterized by a joint sense of vitalityand learning. Based on Spreitzer and colleagues’ (2005) model, we present a comprehensive meta-analysis of antecedents and outcomes of thriving at work (K = 73 independent samples, N = 21,739 employees). Results showed that thriving at work is associated with individual characteristics, such as psychological capital (rc = .47), proactive personality (rc = .58), positive affect (rc = .52), and work engagement (rc = .64). Positive associations were also found between thriving at work and relational characteristics, including supportive coworker behavior (rc = .42), supportive leadership behavior (rc= .44), and perceived organizational support (rc = .63). Moreover, thriving at work is related to important employee outcomes, including health-related outcomes like burnout (rc = -.53), attitudinal outcomes like commitment (rc = .65), and performance-related outcomes like task performance (rc = .35). The results of relative weights analyses suggest that thriving exhibits small, albeit incremental predictive validity above and beyond positive affect and work engagement, for task performance, job satisfaction, subjective health, and burnout. Overall, the findings of this meta-analysis support Spreitzer and colleagues’ (2005) model and underscore the importance of thriving in the work context.
An Individual Differences Investigation of the Relation between Life Event Stress And Working Memory Capacity
Authors: Goller Haley
Published: April 2019

The effects of stress in both academic and social settings are well established. However, the effects of stress on cognitive functioning are less so. This study explored the relation between life event stress and cognitive functioning; first by attempting to replicate a negative association between life event stress and working memory capacity and then by testing if the propensity to mind wander, the emotional valence of mind wandering, or the tendency to ruminate are potential mechanisms through which life stress can affect working memory capacity. In addition, I tested if trait level mindfulness is a protective factor against the effects of life stress on working memory capacity. Negative life event stress did not correlate with working memory capacity. Mind wandering, the valance of mind wandering, rumination, and trait level mindfulness did not serve as mediators in the relationship between working memory capacity and negative life event stress. When compared to neutral and positively valanced mind wandering, negatively valanced mind wandering was not more harmful to SART reaction time. However, when compared to neutral, but not positively valanced mind wandering, negatively valanced mind wandering was more harmful to SART accuracy. Finally, no evidence was found for trait level mindfulness serving as a protective factor.
