    Suicide has become a national and global problem, with the prevalence of suicide attempts increasing in recent years (Brown, Henriques, Sosdjan, & Beck, 2004; Kessler, Borges, & Walters, 1999). Even though research on suicide has identified risk factors and demographic characteristics to help aid in predicting who is at risk for attempting suicide, predictive models of intent of suicide have been unsuccessful in identifying particular individuals at risk of eventually dying by suicide (Cassells, Paterson, Dowding, & Morrison, 2005; Goldstein, Black, & Nasrallah, 1991; Powell, Geddes, Deeks, Goldacre, & Hawton, 2000). The purpose of this study is to propose an alternative framework to studying suicide by utilizing the theory of planned behavior to explain variables associated with suicidal ideation and intent. Differences in individual attitudes, beliefs, and social norms were also compared to levels of depression and hopelessness to help understand the components that contribute to suicidal ideation. The results revealed that the theory of planned behavior variables explained 49% of the variance in suicidal ideation, with perceived behavioral control accounting for the largest proportion of the variance. The theory of planned behavior variables was also found to explain more variance than depression and hopelessness in suicidal ideation

    Tactile Thresholds are Preserved yet Cortical Sensory Function is Impaired in Chronic Non-Specific Low Back Pain Patients

    Introduction: A substantial amount of evidence points to an alteration in brain structure and function patients with chronic non-specific low back pain (CNSLBP) [1-6]. One interpretation of these findings is that the observed brain changes may represent a disruption of the brain’s representations of the body part and the resultant body perception disturbance may underpin this clinical problem. The current study aimed to investigate sensory dysfunction in CNSLBP. Specifically we aimed to distinguish cortically mediated sensory dysfunction from peripheral dysfunction by comparing simple tactile thresholds with more complex cortically mediated sensory tests Methods: We investigated tactile thresholds (TTH), two point discrimination (TPD) and graphaesthesia over the lumbar spine of 19 CLBP patients and 19 age and sex matched healthy controls as a way of investigating whether CLBP patients present with a perceptual disturbance of their lumbar spine. Differences in performance of the sensory tests was explored using the Mann Whitney U Test and one-way between groups multivariate analysis of variance. Results: We found no difference in tactile threshold between the two groups (P=.0.751). There was a statistically significant difference between controls and LBP for TPD: F(1,36)=10.15, p=.003 and letter error rate: F(1, 36)=6.54 p=0.015. The data indicate that LBP patients had a larger lumbar TPD distance and a greater letter recognition error rate. Discussion: Both TPD and graphaesthesia are dependant on the integrity of the primary sensory cortex [7]. These data support existing findings of perceptual abnormality in chronic back pain [8] and the preservation of tactile thresholds is suggestive of cortical rather than peripheral sensory dysfunction. Amelioration of these abnormalities may present a target for therapeutic intervention

    Advances in the treatment of gastroenteropancreatic neuroendocrine tumors

    Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are a rare and heterogeneous class of neoplasms. While surgical resection is the mainstay of treatment, non-surgical therapies play a role in the setting of unresectable and metastatic disease. The goals of medical therapy are directed both at alleviating symptoms of peptide release and shrinking tumor mass. Biotherapies such as somatostatin analogs and interferon can decrease the secretion of peptides and inhibit their end-organ effects. A second objective for treatment of unresectable GEP-NETs is limiting tumor growth. Options for limiting tumor growth include somatostatin analogs, systemic chemotherapy, locoregional therapies, ionizing radiation, external beam radiation, and newer targeted agents. In particular, angiogenesis inhibitors, tyrosine kinase inhibitors, and mTOR inhibitors have shown early promising results. The rarity of these tumors, their resistance to standard chemotherapy, and the excellent performance status of most of these patients, make a strong argument for consideration of novel therapeutic trials

    Tropical Cyclones and Storm Surge Modelling Activities

    The Global Disasters Alert and Coordination System (GDACS) automatically invokes ad hoc numerical models to analyse the level of the hazard of natural disasters like earthquakes, tsunamis, tropical cyclones, floods and volcanoes. The Tropical Cyclones (TCs) are among the most damaging events, due to strong winds, heavy rains and storm surge. In order to estimate the area and the population affected, all three types of the above physical impacts must be taken into account. GDACS includes all these dangerous effects, using various sources of data. The JRC set up an automatic routine that includes the TC information provided by the Joint Typhoon Warning Center (JTWC) and the National Oceanic and Atmospheric Administration (NOAA) into a single database, covering all TCs basins. This information is used in GDACS for the wind impact and as input for the JRC storm surge system. Recently the global numerical models and other TC models have notably improved their resolutions, therefore one of the first aim of this work is the assessment and implementation of new data sources for the wind, storm surge and rainfall impacts in GDACS. Moreover the TC modelling workflow has been revised in order to provide redundancy, transparency and efficiency while addressing issues of accuracy and incorporation of additional physical processes. The status of development is presented along with the outline of future steps.JRC.E.1-Disaster Risk Managemen

    School Counselor Educators as Educational Leaders Promoting Systemic Change

    Get PDF
    If the full impact of the transformation of the school counseling profession is to be enacted, it is incumbent upon school counselor educators to model the same skills and professional mindset that are expected of practicing school counselors. Specifically, school counselor educators can serve as leaders within their educational communities in order to promote systemic change that will remove barriers to student success. The notion of school counselor educators as educational leaders represents a philosophical and behavioral congruence that churns the professional ecosystem, from the professor to the practitioner to the P-12 student. This article outlines the role that school counselor educators can play in modeling leadership and other essential skills for the profession
