The Construction of SCM in GRAPES and Its Applications in Two Field Experiment Simulations

T A Single Column Model (SCM) for Global and Regional Atmospheric Prediction Enhanced System (GRAPES) is constructed for the purpose of evaluating physical process parameterizations. Two observational datasets including Wangara and the third Global Energy and Water Cycle Experiment Atmospheric Boundary Layer Study (GABLS-3) SCM field observations have been applied to evaluate this SCM. By these two numerical experiments, the GRAPES_SCM is verified to be correctly constructed. Furthermore, the interaction between the land surface process and atmospheric boundary layer (ABL) is discussed through the second experiment. It is found that CASE3 (CoLM land surface scheme coupled with ABL scheme) simulates less sensible heat fluxes and smaller surface temperature which corresponds with its lower potential temperature at the bottom of the ABL. Moreover, CASE3 simulates turbulence that is weaker during the daytime and stronger during nighttime, corresponding with its wind speed at 200 m which is bigger during daytime and smaller during nighttime. However, they are generally opposite in CASE2 (SLAB coupled with ABL). The initial profile of the water vapor mixing ratio is artificially increased by the experiment setup which results in the simulated water vapor mixing becoming wetter than actually observed. CASE1 (observed surface temperature taken as lower thermal forcing) and CASE2 have no soil moisture prediction and simulate a similar water vapor mixing ratio, while CASE3 has a soil moisture prediction and simulates wetter. It is also shown that the time step may affect the stabilization of the ABL when the vertical levels of the SCM are fixed.

BASIC ELEMENTS IN THE PROCESS OF PSYCHOTHERAPY: A RESEARCH STUDY.

TESTED THE HYPOTHESIS, BASED ON CLIENT-CENTERED THEORY, THAT MOVEMENT IN THE CLIENT'S PROCESS BEHAVIOR (MANNER OF PROBLEM EXPRESSION, DEPTH OF PERSONAL EXPLORATION, AND MANNER OF RELATING TO THE THERAPIST) IS POSITIVELY RELATED TO THE LEVEL OF THE THERAPIST CONDITIONS (CONGRUENCE, EMPATHIC UNDERSTANDING, AND POSITIVE REGARD) AND TO CASE OUTCOME (PRE- TO POSTTEST CHANGES). SS WERE 15 HOSPITALIZED SCHIZOPHRENIC THERAPY CASES. THERAPIST CONDITIONS AND PATIENT PROCESS VARIABLES WERE RATED FROM TAPE-RECORDED SEGMENTS OF THERAPY INTERVIEWS. IT WAS FOUND THAT PATIENT PROCESS MOVEMENT OVER THERAPY WAS NOT RELATED TO LEVEL OF THERAPIST CONDITIONS NOR TO CASE OUTCOME. LEVEL OF THERAPIST CONDITIONS AND LEVEL OF PATIENT PROCESS BEHAVIOR WERE POSITIVELY RELATED TO CASE OUTCOME AND TO THE PERCEPTION OF THERAPIST CONDITIONS BY THE PARTICIPANTS. SPECIFIC LEVELS OF THERAPIST AND PATIENT BEHAVIOR WERE ASSOCIATED WITH SUCCESSFUL OUTCOME. (20 REF.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

INVARIANCE OF ZERO-POINT SCALING OVER CHANGES IN STIMULUS CONTEXT.

HICKS AND CAMPBELL RECENTLY REPORTED A SERIES OF ATTEMPTS TO LOCATE A RATIONAL ORIGIN ON EACH OF SEVERAL PSYCHOLOGICAL SCALES, BY UTILIZING AN ADDITIVE SCALE MODEL IN CONJUNCTION WITH THURSTONE'S CASE V PAIRED COMPARISONS OR WITH A CATEGORY-JUDGMENT SCALING METHOD. THEY CONCLUDED THAT (1) THE ADDITIVITY MODEL APPLIED ALMOST EQUALLY WELL TO JUDGMENTS OF BIRTHDAY GIFTS, TRAFFIC VIOLATIONS, AND BEHAVIOR DESCRIPTIONS; (2) THE LOCATION OF A RATIONAL ZERO POINT WAS STRONGLY AFFECTED BY THE RANGE OR "CONTEXT" OF STIMULI INCLUDED, AND (3) EQUIVALENT FINDINGS RESULTED FROM PAIRED-COMPARISONS OR CATEGORY-JUDGMENT SCALING METHODS. THE PRESENT REPORT WAS MOTIVATED BY A CRITICAL EXAMINATION OF THE HICKS-CAMPBELL ASSUMPTIONS CONCERNING DISCRIMINAL DISPERSIONS OF SINGLE AND COMPOSITE (DOUBLE) STIMULI. BY REPLACING THE CASE V ASSUMPTION OF EQUAL DISPERSION OVER ALL STIMULI WITH A CASE VI ASSUMPTION THAT DISPERSION IS LINEARLY RELATED TO SCALE VALUE, REANALYSIS OF THEIR DATA PROVIDES RESULTS UNIFORMLY MORE SUPPORTIVE OF THE ADDITIVE SCALE MODEL, AND SUPPORTIVE OF THE INVARIANCE OF THE RATIONAL ORIGIN OVER CHANGES IN STIMULUS CONTEXT.

ACCURACY VERSUS VALIDITY IN PERSON PERCEPTION.

24 UNDERGRADUATE PSYCHOLOGY STUDENTS WERE ASKED TO PREDICT EVENTS FROM 3 DIFFERENT CASE HISTORIES AND THEN TO WRITE PERSONALITY CONCEPTUALIZATIONS FOR THE 3 CASES. THE PREDICTIVE VALIDITY OF THE CONCEPTUALIZATIONS WAS MEASURED BY HAVING NEW JUDGES READ THEM AND MAKE A NEW SERIES OF PREDICTIONS ABOUT THE SAME CASES. THE ACCURACY OF THE ORIGINAL JUDGES IN MAKING THEIR PREDICTIONS WAS SIGNIFICANTLY NEGATIVELY CORRELATED WITH THE PREDICTIVE VALIDITY OF THEIR CONCEPTUALIZATIONS; I.E., THE MOST ACCURATE PREDICTORS TENDED TO WRITE THE LEAST VALID CONCEPTUALIZATIONS. THERE WERE INDICATIONS THAT THE ACCURATE PREDICTORS ADOPTED AN EMPATHIC APPROACH TO THE CASE MATERIAL, WHILE VALID CONCEPTUALIZERS WERE MORE ANALYTIC AND EVALUATIVE IN APPROACH. SLIGHT EVIDENCE WAS PRESENTED TO THE EFFECT THAT TRAINING IN PSYCHOLOGY WAS NEGATIVELY RELATED TO ACCURACY, BUT POSITIVELY RELATED TO VALIDITY.

Phenformin-associated lactic acidosis due to imported phenformin

OBJECTIVE: To emphasize the continued incidence of phenformin-associated lactic acidosis. CASE REPORT: We report a case of phenformin-associated lactic acidosis in a Chinese man who received phenformin while in China. Diagnosis was made; the patient was treated appropriately and survived. COMMENTS: Phenformin-associated lactic acidosis may still occur in the U.S.     

Complex injuries of the dorsum of the hand. Therapeutic reflections apropos of 2 cases

We report 2 similar cases of severe injury of the dorsum of the hand, both treated in emergency. FIRST CASE: A 37-year-old right handed male truck driver was admitted with a complex severe injury of the dorsum of his right hand following a traffic accident. He had a combined large defect involving skin, tendons and bone. A complex reconstruction was performed using a massive iliac crest allograft, a tendon graft and a free serratus anterior flap in a one stage procedure, eight hours after the injury. A skin graft was done later. Two years later the functional and esthetic results are good. SECOND CASE: A 37-year-old woman was admitted with a severe injury of the dorsum of her right hand following a traffic accident. She had a large combined defect involving skin, tendon and bone. A complex reconstruction was carried out using a large iliac crest autograft, a multiple tendon graft and a free latissimus dorsi flap, in one stage 6 hours after the trauma. Eight months later the functional result is partial but useful for the daily activities of the patient.     

Trichomoniasis in a postmenopausal woman cured after discontinuation of estrogen replacement therapy

BACKGROUND: Epidemiologic and experimental data suggest that estrogen has a salutary effect on Trichomonas vaginalis. CASE: A metronidazole-allergic postmenopausal woman was cured of vaginal trichomoniasis in association with discontinuation of estrogen replacement therapy. CONCLUSION: Hormonal manipulation should be studied for the management of women with trichomoniasis who are allergic to metronidazole or who are infected with metronidazole-resistant strains of Trichomonas vaginalis.     

The Dall-Miles cable and plate system for periprosthetic femoral fractures

BACKGROUND: Spontaneous bilateral ectopic pregnancy is a rare event and difficult to diagnose preoperatively. CASE: A unique case occurred of bilateral ectopic pregnancy involving the left fallopian tube and right cornu, or interstitial segment. CONCLUSION: This case demonstrates the difficulty in diagnosing heterotopic pregnancies and in particular those pregnancies with an interstitial component and also demonstrates the limits of ultrasound and laparoscopy in making such a diagnosis.     

Bilateral medial bulbar infarct related to dolichoectasia of the vertebral artery

INTRODUCTION AND CLINICAL CASE: A 58-year-old hypertensive man presented with the sudden onset of quadriplegia and inability to protrude the tongue. Magnetic resonance imaging showed a bilateral medial medullary infarction associated with an abnormally dilated and partially occluded vertebral artery. CONCLUSION: This is the first clinicoradiological report of a bilateral medial medullary infarction related to vertebral artery dolichoectasia.
