The Deepwater Horizon oil drilling rig exploded on April 20, 2010, off the coast of Louisiana in the Gulf of Mexico. Following the spill, British Petroleum, leaser of the rig, set up a funding institution known as the Gulf of Mexico Research Initiative (GoMRI) to support research and understanding of the spill on the environments and peoples of the gulf. This outreach project was created alongside research of the RECOVER consortium, funded by GoMRI, to communicate what is happening within research labs around the country to understand the effect that the spill had on fish in pelagic and coastal regions of the gulf. The outreach project is composed of a short film (Deepwaters: The Science of a Spill, 18 min) and related outreach materials posted to Instagram (@FishandOilSpills).

Research has shown that well-trained staff within early and intensive behavioral intervention (EIBI) provide more effective treatment. An important part of training is learning the vocabulary and concepts of treatment. This aids in conceptual understanding of the principles and procedures. The process of learning behavioral concepts also develops the necessary verbal repertoire needed to communicate among members of a community of practice; a group of people who have common reinforcers and are working toward a common goal. Learning to tact a series of sequential descriptions, or verbally narrate, exemplary teaching interactions should be a goal when teaching behavior analysis because it is how we, as a community, interact and establish an understanding of behavior analysis. The purpose of the current study is to train novice behavior analysts to narrate exemplary intervention sequences that are responsive, flexible, and effective teaching interactions. The effects of the training were evaluated using a multiple baseline design across training conditions, replicated across 3 participants. The results suggest that the training was effective in increasing the number of narrative statements as well as the number of narrative statements related to five critical features of a teaching interaction and the relations between those features. The results are …

Training parents of a child with autism to increase the frequency of their child's social behavior may improve the quality of parent-child interactions. The purpose of this methodological study was to develop a direct observation method for rapidly sampling social harmony between parents and their toddlers with autism during parent training interactions. The current study used a pre and post probe design, with benchmark comparisons to test the discriminability of the measurement protocol across two sets of data. The first set of data came from pre and post training videos from a parent training program for children with a diagnosis of autism or at risk for a diagnosis. The second set of data came from videos of typically developing toddlers and their parents. The results of the study show that the measurement system differentiated in the level of harmonious engagement between the benchmark sample and the sample including children diagnosed with autism. The results are discussed in the context of future directions and the utility of the measurement system for behavior analytic practices in parent training and other settings where rapport and complex interactional behaviors are an intervention priority.

Software as a service (SaaS) is a primary working pattern and a significant application model for next generation Internet application. Web GIS services are the new generation of the Software as a service that can provide the hosted spatial data and GIS functionalities to the practical customized applications. This study focused on developing a webGIS based application, Soil Moisture-Based Irrigation Scheduling Tool (SMIST), for predicting soil moisture in the next seven days using the soil moisture diagnostic equation (SMDE) and the upcoming seven precipitation forecasts made by the National Weather Service (NWS), and ultimately producing an accurate irrigation schedule based on the predicted soil moisture. The SMIST is expected to be capable of improving the irrigation efficiency to protect groundwater resources in the Texas High Plains and reducing the cost of energy for pumping groundwater for irrigation, as an essential public concern in this area. The SMIST comprised an integration of web-based programs, a Hydrometeorological model, GIS, and geodatabase. It integrates two main web systems, the soil moisture estimating web application for irrigation scheduling based on the soil moisture diagnostic equation (SMDE), and an agricultural field delineation webGIS application to prepare input data and the model parameters. The SMIST takes …

Poly(vinyl chloride)(PVC) wire and cable insulation has poor thermal stability, causing the plasticizer to separate from the PVC chain and produce an oily residue, lowering the tensile elongation at break and thus increasing brittleness. We have added 4 wt.% of three different types of cross-linking agents and antioxidants, as well as mixtures of both, to improve the thermal stability of the plasticizer and tensile properties of PVC after thermal exposure. We performed tensile tests, tribological tests, profilometry, scanning electron microscopy(SEM) and water absorption determination before and after thermal exposure at 136 ℃ for 1 week. After adding the agents, elongation at break increased by 10 to 20 % while the wear rate and water absorption were lower than for the control sample. Less voids are seen in the SEM images after adding these two kinds of agents. The thermal resistance of the PVC cable insulation is best enhanced by combinations of cross-linking agents and antioxidants.

The sudden or violent death of a loved one (e.g., suicide, homicide, accident, etc.) poses unique challenges for the bereaved. Research has found such losses to be associated with higher levels of chronic psychological distress, now termed Persistent Complex Bereavement Disorder in the DSM-5 and Prolonged Grief Disorder in the forthcoming ICD-11. The present study, developed through the lens of Multidimensional Grief Theory (MGT; Kaplow et al., 2013), explored underlying mechanisms and risk and protective factors for both prolonged grief and posttraumatic growth. With a mixed college and community sample of 374 traumatically bereaved adults, results of a path analysis suggest that insecure attachment strategies play a significant role in prolonged grief symptoms through the mediators of identity distress and shattered assumptions. Faced with the traumatic loss of a loved one, the ability and desire to effectively access relationships facilitating intentional processing that promotes cognitive reorganization is predicated on the bereaved's internal working model of attachment. Specifically, attachment anxiety in relation to close others and God, and attachment avoidance in relation to close others, were indirectly associated with prolonged grief. However, attachment avoidance in relation to God was negatively associated with both prolonged grief and posttraumatic growth, and there was …

Intergroup relations and the factors affecting them constitute a subject of recurring interest within the academic community. Social identity theory suggests that group membership and the value we assign to it drives the expression of in-group favoritism and outgroup prejudice, among other intergroup phenomena. The present study examines how (ir)religious identities are related to topic-sentiment polarization in the form of positive in-group and negative outgroup bias during interreligious debates in YouTube commentaries. Drawing from the propositions of social identity theory, six hypotheses were tested. The data for the study, a product of a natural experiment, are comments posted on YouTube commentary sections featuring videos of interreligious debates between (a) Christian and atheist or (b) Christian and Muslim speakers. Using topic-sentiment analysis, a multistage method of topic modeling with latent semantic analysis (LSA) and sentiment analysis, 52,607 comments, for the Christian - atheist debates, and 24,179 comments, for the Christian - Muslim debates, were analyzed. The results offer support (or partial support) to the hypotheses demonstrating identity-specific instances of topic-sentiment polarization to the predicted direction. The study offers valuable insights for the relevance of social identity theory in real-world interreligious interactions, while the successful application of topic-sentiment analysis lends support for …

The current study examines interrelations among family factors in a sample of married couples with children in middle childhood. Specifically, this study tested the associations between parents' mental health, marital satisfaction, and provision of a secure base through emotional sensitivity to the child. We further explored bidirectional and moderation effects between spouses. Participants included 86 heterosexual couples residing in the North Texas community. Using the actor-partner interdependence model, multilevel modeling results indicated that both spouse's mental health symptomology and relationship satisfaction are linked to parent's self-perceived ability to provide a secure base; several gender effects were also found. Additionally, actor relationship satisfaction significantly moderated the association between actor mental health symptomology and secure-base provision. In the context of low actor satisfaction, as the actor's mental health symptomology increases, secure-base provision also increases; however, in the context of high actor satisfaction, as actor's mental health symptomology increases, secure-base provision decreases. Additionally, partner relationship satisfaction significantly moderated the association between partner mental health symptomology and actor secure-base provision. In the context of low partner satisfaction, as partner mental health symptomology increases, actor secure-base provision increases; however, in the context of high partner satisfaction, as partner mental health symptomology increases, actor secure-base provision …

When talking about tonal music, we sometimes tend to take for granted the idea that the tonic should always be clearly established either at the beginning or the end. However, there are composers who sometimes deviate from the normal path by creating different types of riddles or tonal enigmas in their works. Some of these riddles can be solved later on as the piece progresses; yet others may need to bexplained with the help of some external references. This thesis examines three such examples, each of which poses its unique enigma. The second movement of Bruckner's Symphony No. 1 presents a dualism between Ab and F (paralleled by their dominants Eb and C); Brahms's Alto Rhapsody involves an enormous auxiliary cadence spanning 2/3 of the piece and a seemingly plagal cadence which turns out to be authentic with the V suppressed; and eventually, Grieg's setting of Dereinst, dereinst, Gedanke mein provides a paradoxical ending which may be understood as incorporating the composer's attitude towards the text.
