Cognitive control, psychological defense and learning under conflict

Thesis (Ph.D.)--Boston University.This study investigates the nature of a relationship postulated between cognitive behavior under conditions of conflict arousal and certain coping processes of personality. A review of theoretical and experimental studies concerned with the effects on cognition of motivational states in relation with various types of stimulus situations finds consensus concerning the presence or absence of conflict as a determining influence. When conflict is absent cognition is not interfered with; when conflict is present inhibition occurs. Two variables - cognitive control and psychological defense - have been used to account for the effects of drive arousal upon cognitive behavior under conditions of conflict relevant to the drive state. Cognitive control has been defined by varying capacities to make differentially adaptive responses to specified aspects of stimulus fields in the presence of explicitly interfering cues. Defense - either repression or intellectualization - has been defined by varying capacities to recall stimulus material presumed to arouse conflictual drive states. The present study utilizes both experimental variables to account more precisely for the effects of motivational conditions upon cognitive behavior in situations requiring resolution of conflict. Conflict is defined by the presence of competing response tendencies having varying probabilities of occurrence. [TRUNCATED

Email for communicating results of diagnostic medical investigations to patients

<p>Background: As medical care becomes more complex and the ability to test for conditions grows, pressure on healthcare providers to convey increasing volumes of test results to patients is driving investigation of alternative technological solutions for their delivery. This review addresses the use of email for communicating results of diagnostic medical investigations to patients.</p> <p>Objectives: To assess the effects of using email for communicating results of diagnostic medical investigations to patients, compared to SMS/ text messaging, telephone communication or usual care, on outcomes, including harms, for health professionals, patients and caregivers, and health services.</p> <p>Search methods: We searched: the Cochrane Consumers and Communication Review Group Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 1 2010), MEDLINE (OvidSP) (1950 to January 2010), EMBASE (OvidSP) (1980 to January 2010), PsycINFO (OvidSP) (1967 to January 2010), CINAHL (EbscoHOST) (1982 to February 2010), and ERIC (CSA) (1965 to January 2010). We searched grey literature: theses/dissertation repositories, trials registers and Google Scholar (searched July 2010). We used additional search methods: examining reference lists and contacting authors.</p> <p>Selection criteria: Randomised controlled trials, quasi-randomised trials, controlled before and after studies and interrupted time series studies of interventions using email for communicating results of any diagnostic medical investigations to patients, and taking the form of 1) unsecured email 2) secure email or 3) web messaging. All healthcare professionals, patients and caregivers in all settings were considered.</p> <p>Data collection and analysis: Two review authors independently assessed the titles and abstracts of retrieved citations. No studies were identified for inclusion. Consequently, no data collection or analysis was possible.</p> <p>Main results: No studies met the inclusion criteria, therefore there are no results to report on the use of email for communicating results of diagnostic medical investigations to patients.</p> <p>Authors' conclusions: In the absence of included studies, we can draw no conclusions on the effects of using email for communicating results of diagnostic medical investigations to patients, and thus no recommendations for practice can be stipulated. Further well-designed research should be conducted to inform practice and policy for communicating patient results via email, as this is a developing area.</p&gt

Economic value of ecosystem services, minerals and oil in a melting Arctic: a preliminary assessment

The Arctic region is composed of unique marine and terrestrial ecosystems that provide a range of services to local and global populations. However, Arctic sea-ice and permafrost is melting at an unprecedented rate, threatening many of these ecosystems and the services they provide. This short communication provides a preliminary assessment of the quantity, distribution and economic value of key ecosystem services as well as geological resources such as oil and minerals provided by Arctic ecosystems to beneficiaries in the Arctic region and globally. Using biophysical and economic data from existing studies, preliminary estimates indicate that the Arctic currently provides about $$281 billion per year (in 2016 US$) in terms of food, mineral extraction, oil production, tourism, hunting, existence values and climate regulation. However, given predictions of ice-free summers by 2037, many of the ecosystem services may be lost. We hope that this communication stimulates discussion among policy-makers regarding the value of ecosystem services and such geological resources as minerals and oil provided by the Arctic region, and the potential ecosystem losses resulting from Arctic melt, so as to motivate decisions vis a vis climate change mitigation before Arctic ice disappears completely

Advice from a Medical Expert through the Internet on Queries about AIDS and Hepatitis: Analysis of a Pilot Experiment

BACKGROUND: Advice from a medical expert on concerns and queries expressed anonymously through the Internet by patients and later posted on the Web, offers a new type of patient–doctor relationship. The aim of the current study was to perform a descriptive analysis of questions about AIDS and hepatitis made to an infectious disease expert and sent through the Internet to a consumer-oriented Web site in the Spanish language. METHODS AND FINDINGS: Questions were e-mailed and the questions and answers were posted anonymously in the “expert-advice” section of a Web site focused on AIDS and hepatitis. We performed a descriptive study and a temporal analysis of the questions received in the first 12 months after the launch of the site. A total of 899 questions were received from December 2003 to November 2004, with a marked linear growth pattern. Questions originated in Spain in 68% of cases and 32% came from Latin America (the Caribbean, Central America, and South America). Eighty percent of the senders were male. Most of the questions concerned HIV infection (79%) with many fewer on hepatitis (17%) . The highest numbers of questions were submitted just after the weekend (37% of questions were made on Mondays and Tuesdays). Risk factors for contracting HIV infection were the most frequent concern (69%), followed by the window period for detection (12.6%), laboratory results (5.9%), symptoms (4.7%), diagnosis (2.7%), and treatment (2.2%). CONCLUSIONS: Our results confirm a great demand for this type of “ask-the-expert” Internet service, at least for AIDS and hepatitis. Factors such as anonymity, free access, and immediate answers have been key factors in its success
