Probabilistic Determination of the Role of Faults and Intrusions in Helium‐Rich Gas Fields Formation

Natural gas fields with economic helium (>0.3 He %) require the radioactive decay of crustal uranium (U) and thorium (Th) to generate He and tectonic/structural regimes favorable to releasing and concentrating He. An unknown is determining the role of faults and structural features in focusing deep‐seated He sources on shallow accumulations. We tested the correlation between high‐He wells (n = 94) and structural features using a new high‐resolution aeromagnetic survey in the Four Corners area, USA. A depth‐to‐basement map with basement lineaments/faults, an intrusion map, and a flattened basement structural high map were created using Werner deconvolution algorithms by combining magnetic, gravity, and topography data with magnetic and gravity depth profiles. We show quantitatively (via analysis of variance) that a non‐random process controls the relationship between He (>0.3%) and both basement faults and intrusions: 88% of high‐He wells occur <1 km of basement faults; and 85% of high‐He wells occur <1 km of intrusions. As He % increases, the distance to the structural features decreases. Strong spatial/statistical correlations of He wells to both basement faults and intrusions suggest that advective transport via faults/intrusions facilitates He migration. The role of gas phase buoyancy and structural trapping is confirmed: 88% of high‐He occurs within basement structural highs, and 91% of the remaining wells are <1 km from intrusions (potential structural high). We present a composite figure to illustrate how a probabilistic approach can be used as a predictive model to improve He exploration success by targeting zones of intersection of basement faults and intrusions within basement structural highs

Ethical Marketing: Perceptions of Economic Goods and Social Problems

A methodology associated with experimental social psychology was used to ascertain whether there are different ethical overtones perceived in the marketing of different products despite all other aspects of the marketing situation being comparable. The methodology consisted of using four vignettes of marketing strategy with the product utilized being the only element varied across the scenarios. Results indicate that ethical evaluations are product dependent and are more severe for social goods than for traditional economic goods.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Schneiderian first rank symptoms: Reconfirmation of high specificity for schizophrenia

The prevalence of Schneiderian first-rank symptoms (FRS) in 294 consecutive admissions to a research unit was evaluated with reference to their diagnostic distribution (SADS/RDC). Thirty-five of 58 patients with schizophrenia had FRS, as compared to nine of 190 patients with major depressive disorder. All patients with two or more FRS received a diagnosis of schizophrenia. In the absence of organic or toxic etiology, the specificity of FRS for schizophrenia was 95% and their predictive value was 90%. These findings indicate that FRS should be regarded as strongly suggestive of schizophrenia in the absence of an organic syndrome.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/65636/1/j.1600-0447.1987.tb02807.x.pd

A Theoretical Analysis of the Feasibility of a Singularity-Induced Micro-Electroporation System

Electroporation, the permeabilization of the cell membrane lipid bilayer due to a pulsed electric field, has important implications in the biotechnology, medicine, and food industries. Traditional macro and micro-electroporation devices have facing electrodes, and require significant potential differences to induce electroporation. The goal of this theoretical study is to investigate the feasibility of singularity-induced micro-electroporation; an electroporation configuration aimed at minimizing the potential differences required to induce electroporation by separating adjacent electrodes with a nanometer-scale insulator. In particular, this study aims to understand the effect of (1) insulator thickness and (2) electrode kinetics on electric field distributions in the singularity-induced micro-electroporation configuration. A non-dimensional primary current distribution model of the micro-electroporation channel shows that while increasing insulator thickness results in smaller electric field magnitudes, electroporation can still be performed with insulators thick enough to be made with microfabrication techniques. Furthermore, a secondary current distribution model of the singularity-induced micro-electroporation configuration with inert platinum electrodes and water electrolyte indicates that electrode kinetics do not inhibit charge transfer to the extent that prohibitively large potential differences are required to perform electroporation. These results indicate that singularity-induced micro-electroporation could be used to develop an electroporation system that consumes minimal power, making it suitable for remote applications such as the sterilization of water and other liquids

Has Behavioral Science Tumbled Through the Biological Looking Glass? Will Brief, Evidence-Based Training Return It From the Rabbit Hole?

Time constraints and professional demands leave practicing professionals unlikely to enroll in extended training such as a semester-long graduate course. Thus, the three-hour continuing education format has become a standard for those in practice. One may ask what sorts of training strategies optimize that format. To explore that, a three hour training program for seventy-six practicing mental health professionals, most of whom self-identified as psychologists, was devised. It made use of primarily antecedent techniques that have been shown to bring about changed perceptions on a number of topics. Content focused on two areas of importance to behavior analysts, the culture’s increasing acceptance of the biological causation model of disorders such as attentiondeficit hyperactivity disorder (ADHD), unipolar depression, anxiety disorders, and schizophrenia, and the field’s increasing reliance on medications, often to the exclusion of behavioral methods. Pre-post assessment showed that participants had changed their thinking regarding the two content areas. The authors caution that participants’ changed opinions may serve as setting events to changes in practice, but those changes are verbal. One must not assume changes in practice techniques will automatically occur

Perception of Biological Motion in Schizophrenia and Healthy Individuals: A Behavioral and fMRI Study

Background: Anomalous visual perception is a common feature of schizophrenia plausibly associated with impaired social cognition that, in turn, could affect social behavior. Past research suggests impairment in biological motion perception in schizophrenia. Behavioral and functional magnetic resonance imaging (fMRI) experiments were conducted to verify the existence of this impairment, to clarify its perceptual basis, and to identify accompanying neural concomitants of those deficits. Methodology/Findings: In Experiment 1, we measured ability to detect biological motion portrayed by point-light animations embedded within masking noise. Experiment 2 measured discrimination accuracy for pairs of point-light biological motion sequences differing in the degree of perturbation of the kinematics portrayed in those sequences. Experiment 3 measured BOLD signals using event-related fMRI during a biological motion categorization task. Compared to healthy individuals, schizophrenia patients performed significantly worse on both the detection (Experiment 1) and discrimination (Experiment 2) tasks. Consistent with the behavioral results, the fMRI study revealed that healthy individuals exhibited strong activation to biological motion, but not to scrambled motion in the posterior portion of the superior temporal sulcus (STSp). Interestingly, strong STSp activation was also observed for scrambled or partially scrambled motion when the healthy participants perceived it as normal biological motion. On the other hand, STSp activation in schizophreni

Reframing obesity: a critical discourse analysis of the UK’s first social marketing campaign

This paper presents a critical discourse analysis of the UK government’s ‘Change4Life’ antiobesity social marketing campaign, which uses colourful cartoon characters and simplified messages to ‘reframe’ the issue of obesity, and encourage the public to take an active role in addressing this policy problem. It stems from a wider political context in which insights from behavioural economics (‘nudge’) are increasingly turned to for solutions to policy problems. The approach particularly emphasises the importance of carefully crafted communication in securing public compliance with desired policy outcomes, and has gained considerable attention in political science, economics, and health research. This paper contributes to that growing debate by offering a systematic textually-oriented critical analysis of the discourse of nudge. It maps the public, private, and third sector practices comprising this campaign, and critically examines the underlying balance of power and vested interests. Detailed analysis of the launch advert and surrounding policy documents reveals how scientific claims about obesity are recontextualised, simplified, and distorted in this campaign. It is further argued that the use of behavioural psychology legitimate individualised policy solutions, squeezing out public deliberation over the complex structural causes of obesity

Mourning and melancholia revisited: correspondences between principles of Freudian metapsychology and empirical findings in neuropsychiatry

Freud began his career as a neurologist studying the anatomy and physiology of the nervous system, but it was his later work in psychology that would secure his place in history. This paper draws attention to consistencies between physiological processes identified by modern clinical research and psychological processes described by Freud, with a special emphasis on his famous paper on depression entitled 'Mourning and melancholia'. Inspired by neuroimaging findings in depression and deep brain stimulation for treatment resistant depression, some preliminary physiological correlates are proposed for a number of key psychoanalytic processes. Specifically, activation of the subgenual cingulate is discussed in relation to repression and the default mode network is discussed in relation to the ego. If these correlates are found to be reliable, this may have implications for the manner in which psychoanalysis is viewed by the wider psychological and psychiatric communities
