    Title Workplace Safety: a Meta-analysis of the Roles of Person and Situation Factors.
    Date October 2009
    Journal The Journal of Applied Psychology
    Excerpt

    Recent conceptual and methodological advances in behavioral safety research afford an opportunity to integrate past and recent research findings. Building on theoretical models of worker performance and work climate, this study quantitatively integrates the safety literature by meta-analytically examining person- and situation-based antecedents of safety performance behaviors and safety outcomes (i.e., accidents and injuries). As anticipated, safety knowledge and safety motivation were most strongly related to safety performance behaviors, closely followed by psychological safety climate and group safety climate. With regard to accidents and injuries, however, group safety climate had the strongest association. In addition, tests of a meta-analytic path model provided support for the theoretical model that guided this overall investigation. The implications of these findings for advancing the study and management of workplace safety are discussed.

    Title On the Role of Positive and Negative Affectivity in Job Performance: a Meta-analytic Investigation.
    Date March 2009
    Journal The Journal of Applied Psychology
    Excerpt

    Although interest regarding the role of dispositional affect in job behaviors has surged in recent years, the true magnitude of affectivity's influence remains unknown. To address this issue, the authors conducted a qualitative and quantitative review of the relationships between positive and negative affectivity (PA and NA, respectively) and various performance dimensions. A series of meta-analyses based on 57 primary studies indicated that PA and NA predicted task performance in the hypothesized directions and that the relationships were strongest for subjectively rated versus objectively rated performance. In addition, PA was related to organizational citizenship behaviors but not withdrawal behaviors, and NA was related to organizational citizenship behaviors, withdrawal behaviors, counterproductive work behaviors, and occupational injury. Mediational analyses revealed that affect operated through different mechanisms in influencing the various performance dimensions. Regression analyses documented that PA and NA uniquely predicted task performance but that extraversion and neuroticism did not, when the four were considered simultaneously. Discussion focuses on the theoretical and practical implications of these findings. (PsycINFO Database Record (c) 2009 APA, all rights reserved).

    Date October 2007
    Journal Military Medicine
    Excerpt

    OBJECTIVE: This article discusses issues regarding the usage of psychotropic medications during military deployments, with emphasis on Operation Iraqi Freedom. METHOD: The role of psychotropic medications in the Army combat stress control doctrine is reviewed and compared with operational experiences of psychiatrists who have deployed to Iraq, Bosnia, and Egypt. RESULTS: Many issues regarding psychotropic medications experienced by deployed psychiatrists are not discussed in the Army combat stress control doctrine. CONCLUSION: The advent of new psychotropic medications, the changes in the types of conflicts fought, and the role of National Guard and Reserve forces in current conflicts have all had an impact on the role and usage of psychotropic medications during military deployments.

    Title Descemet's Stripping Automated Endothelial Keratoplasty in Intraoperative Floppy-iris Syndrome: Suture-drag Technique.
    Date August 2007
    Journal Journal of Cataract and Refractive Surgery
    Excerpt

    Descemet's stripping automated endothelial keratoplasty avoids a full-thickness corneal procedure and provides rapid visual rehabilitation. Success depends on positioning the graft successfully while minimizing intraoperative donor endothelial trauma. Previously described techniques for graft insertion may be problematic in patients with intraoperative floppy-iris syndrome, anatomically shallow or unstable anterior chambers, or increased intraoperative posterior vitreous pressure. We describe an alternative called the suture-drag technique that may facilitate lamellar endothelial graft insertion in these special circumstances.

    Title Continuous Intraocular Pressure Recordings During Lamellar Microkeratotomy of Enucleated Human Eyes.
    Date July 2007
    Journal Journal of Cataract and Refractive Surgery
    Excerpt

    PURPOSE: To analyze the course of intraocular pressure (IOP) during lamellar microkeratotomy (LMK) in enucleated human eyes using 3 microkeratome systems. SETTING: Department of Ophthalmology, Texas Tech University Health Sciences Center, Lubbock, Texas, U.S.A. METHODS: Sixteen enucleated human globes were cannulated through the optic nerve, and IOP was recorded continuously while the eyes had standard LMK flap creation. Three microkeratomes were used: Carriazo-Barraquer (Moria Inc.), Innovatome (Innovative Optics Inc.), and Hansatome (Bausch & Lomb). RESULTS: During the vacuum affixation phase, the IOP reached a mean plateau of 97.9 mm Hg with the Hansatome, 135.8 mm Hg with the Innovatome, and 150.0 mm Hg with the Carriazo-Barraquer. During applanation and cutting, the IOP rose to mean plateau of 154.7 mm Hg, 151.8 mm Hg, and 175.8 mm Hg, respectively. Statistical analysis using Kruskal-Wallis testing suggested a difference in mean IOP elevation between the 3 microkeratomes during the vacuum affixation phase (P = .0394) but no difference during the applanation and cutting phase (P = .506). CONCLUSION: The IOP during LMK was higher than previously reported, and this may increase the risk for complications in certain patient groups.

    Title Giant Retroperitoneal Sarcoma: a Case Report and Review of the Management of Retroperitoneal Sarcomas.
    Date January 2003
    Journal The American Surgeon
    Excerpt

    A 42-year-old man presented with lower abdominal pain and a vague abdominal mass. He underwent resection of a well-differentiated liposarcoma arising from his retroperitoneum measuring 50 cm and weighing 11.7 kg (25.8 lb). This is the second largest retroperitoneal soft-tissue sarcoma (RSTS) that has been reported. Over the last 15 years 1123 patients with RSTS in 25 series have been reported with a mean tumor size of 15.7 cm. RSTS represents 0.10 to 0.15 per cent of all malignancies but 45 per cent of all retroperitoneal tumors. Diagnosis and treatment of RSTS can be extremely challenging for a general surgeon. Symptoms are nonspecific and may occur only after the tumor is very large. Abdominal discomfort is the presenting complaint in 60 to 70 per cent of patients and palpable mass in 70 to 80 per cent. Treatment of RSTS remains surgical. Multiple trials of chemotherapy and radiation therapy show no survival benefit. The only successful treatment of this tumor is complete excision; 51.4 per cent of tumors can be completely excised, and 50.2 per cent of these excisions include adjacent organs. Long-term prognosis without complete excision is grim with average 5- and 10-year survival rates of 16.7 and 8.0 per cent. With aggressive surgical therapy survival is increased to 58.0 and 39.6 per cent.

    Title Community Meetings on a Military Inpatient Psychiatric Unit: a Question of Balance.
    Date February 2001
    Journal Military Medicine
    Excerpt

    Community meetings are a mainstay of any inpatient psychiatric unit. Although they differ in frequency, attendance, leadership, and size, they all maintain a similar purpose of acculturating the members to the values of the ward and encouraging responsible behavior and effective communication. The military inpatient psychiatric unit is no different, although it does have several unique factors that affect the management of the community meeting. Specifically, these factors are the inherent military rank structure, which often conflicts with the rank of staff and other patients, the incorporation of a civilian population into a military culture, and a greater focus on patient transitions from military to civilian society. We describe and discuss the common variables of community meetings, elucidate how the military aspects affect the meeting, and offer potential suggestions for the management of this unique large dynamic group.

    Title Intraislet Regulation of Pancreatic Polypeptide Secretion in the Isolated Perfused Rat Pancreas.
    Date December 1997
    Journal Pancreas
    Excerpt

    The present study is to determine if intraislet insulin or somatostatin regulate pancreatic polypeptide (PP) secretion in the isolated perfused rat pancreas by infusing insulin or somatostatin antisera. Isolated rat pancreata were stimulated with either 16.7 mM glucose (G) alone, G with antisomatostatin antibody (G + SA), or G with antiinsulin antibody (G + IA). G inhibited PP secretion -22 +/- 9.5 pM below basal, a decrease of 9 +/- 6.3% (n = 6; p = NS), G + IA inhibited PP secretion -10 +/- 27.2 pM below basal, a decrease of 20 +/- 15% (n = 7, p = NS), and G + SA stimulated PP secretion 18 +/- 7.1 pM above basal, an increase of 26 +/- 5% (n = 6; p < 0.05). G stimulated insulin secretion 3,144 +/- 210 pM above basal (n = 6, p < 0.05), and G + SA stimulated insulin secretion 2,695 +/- 195 pM above basal (n = 7; p < 0.05 vs. baseline, p = NS vs. G alone). G stimulated C-peptide secretion 886 +/- 175 pM above basal (n = 6; p < 0.05), G + SA stimulated C-peptide secretion 847 +/- 102 pM above basal (n = 7; p < 0.05, p = NS vs. G alone), and G + IA stimulated C-peptide secretion 834 +/- 93 pM above basal (n = 7; p < 0.05, p = NS vs. G alone). These data demonstrate that infusion of SA results in significant stimulation of PP secretion during high-G infusion, whereas IA has no effect. Infusions of SA or IA at the doses used have no effect on G-stimulated insulin or C-peptide secretion. This suggests that intraislet somatostatin may be an inhibitory regulator of PP secretion in the isolated perfused rat pancreas.

The principal features of the syndrome and the management of this case are discussed.

    Title The Efficacy of Two Comprehensive Perinatal Programs on Reducing Adverse Perinatal Outcomes.
    Date October 1995
    Journal American Journal of Preventive Medicine
    Excerpt

    Through the collaboration among University of California at Berkeley School of Public Health, Samuel Merritt College, and a private nonprofit, community-based medical center, the adequacy of two perinatal programs was assessed based on the pregnancy outcomes of teenaged Medi-Cal clients. Historical data from June 1991 to June 1992 were compiled on the pregnancy outcomes of 312 Medi-Cal clients, 12-18 years of age, delivering at the study medical center in Oakland, California. The effect of enrollment in two special perinatal programs, Comprehensive Perinatal Services Program (CPSP) and a school-based program, the Comprehensive Teenage Pregnancy and Parenting Program (CTAPPP), on the occurrence of adverse perinatal outcomes was examined. Adverse perinatal outcomes were defined as the occurrence of one of the following: low birthweight (< 2,500 grams), gestational age less than 37 weeks, or admission to the neonatal intensive care unit (NICU), not related to congenital syphilis. The percentage of teens experiencing adverse perinatal outcomes was 10.9% at the study hospital. No significant association was observed between CTAPPP enrollment and reduced adverse perinatal outcomes, but CPSP enrollment was associated with reduced adverse perinatal outcomes. This association persisted after controlling for potential confounders, including substandard prenatal care, which were also found to be risk factors for adverse perinatal outcomes. Enrollment in both programs simultaneously was not associated with a reduction in adverse outcomes. The significant association between CPSP enrollment and reduced adverse perinatal outcomes indicates that a more comprehensive prenatal program may be beneficial in improving birth outcomes, specifically among high-risk teenage populations.(ABSTRACT TRUNCATED AT 250 WORDS)

    Title Axially Symmetric Geodesic Lenses.
    Date
    Journal Applied Optics
    Excerpt

    A procedure was developed and used to obtain the optimal shape of corrected aspheric geodesic lenses for F-numbers ranging from 3 to 15. This optimization procedure allows the (constant) refractive index, lens radius, and focal length to be used as independent design parameters. Results of the increase in size of the first diffraction spot and shift in the focal plane caused by perturbations in a lens's shape have been included for several lenses with F-numbers between 3 and 10.

    Title Dark-adapted Pupil Diameter As a Function of Age Measured with the Neuroptics Pupillometer.
    Date
    Journal Journal of Refractive Surgery (thorofare, N.j. : 1995)
    Excerpt

    PURPOSE:To measure the dark-adapted pupil diameter of normal research participants in their second through ninth decades of life, using the NeurOptics pupillometer (Neuroptics Inc). METHODS:Individuals aged 18 to 80 years with no history of eye disease or injury, intraocular surgery, or use of systemic antihistamines or opiates were recruited. After 2 minutes of adaptation at 1 lux illumination, the right dark-adapted pupil diameter was measured using the NeurOptics pupillometer, with accommodation controlled by distance fixation. The NeurOptics pupillometer reported a mean dark-adapted pupil diameter and a standard deviation of the mean, which were analyzed as a function of age-decade. RESULTS:Two-hundred sixty-three individuals participated. For participants aged 18 to 19 years (n=6), the mean dark-adapted pupil diameter was 6.85 mm (range: 5.6 to 7.5 mm); 20 to 29 years (n=66), 7.33 mm (range: 5.7 to 8.8 mm); 30 to 39 years (n=50), 6.64 mm (range: 5.3 to 8.7 mm); 40 to 49 years (n=51), 6.15 mm (range: 4.5 to 8.2 mm); 50 to 59 years (n=50), 5.77 mm (range: 4.4 to 7.2 mm); 60 to 69 years (n=30), 5.58 mm (range: 3.5 to 7.5 mm); 70 to 79 years (n=6), 5.17 mm (range: 4.6 to 6.0 mm); and 80 years (n=4), 4.85 mm (range: 4.1 to 5.3 mm). These values were consistent with studies using infrared photography. The standard deviation was >0.1 mm in 10 (3.8%) participants, all of whom were younger than 55 years. CONCLUSIONS:The dark-adapted pupil diameter is an important clinical variable when planning refractive surgery. Surgeons can compare a patient's dark-adapted pupil diameter with the results of this population study to identify outlier measurements, which may be erroneous, and repeat testing prior to surgery.
