Mortality salience and worldview defense: the effect of death awareness and self-esteem on multicultural counseling competence

The purpose of this study, based on Terror Management Theory (TMT; Solomon et al., 1991) and Multicultural Counseling Competency literature, was to investigate a) how increased death awareness affects counselors' self evaluations of their MCCs, b) how self esteem moderates the effects of death reminders on counselors' self evaluations of their MCCs, and c) how demographic variables affect counselors' self evaluations of their MCCs following death reminders. 141 master's and doctoral level counseling students enrolled in a CACREP-accredited counseling program in the Southeast or Southwest regions of the United States were randomly assigned to either a death awareness group (experimental group) or a control group. Participants in the death awareness group experienced increased death awareness prior to completing the Multicultural Counseling Inventory (MCI; Sodowsky, 1994); and participants in the control group completed the MCI prior to experiencing increased death awareness. A one-way ANOVA was run to test the difference between groups. Results revealed that participants in the death awareness group self rated their MCCs (including the MCI Overall scale and the MCI Knowledge, MCI Skills, and MCI Relationship subscales) lower than did the control group. No differences between groups were revealed on the MCI Awareness subscale. A multiple regression using the general linear model was run to analyze the effects of conscious death fear on counseling students' perceived MCCs. Results indicated that death concern did not affect counseling students' self perceived MCCs. Also a series of linear regressions were run to understand the moderating effect of self esteem, multicultural training, and other demographic variables on counseling students' perceived MCCs follow increased death awareness. Results revealed that self esteem and multicultural training did not moderate the effect of increased death awareness on counseling students' self perceived MCCs. In partial support of the research hypotheses, results also revealed that, aside from graduate level (master's and doctoral students), demographic variables did not have a moderating effect on increased death awareness. This study is a first step in a research agenda aimed at understanding the effect of increased death awareness on counselors' competence in working with diverse clients. This study contributes to the MCC and TMT bodies of literature, particularly, the practical application of TMT, and to the training of multiculturally competent counselors. It is anticipated that, through this study and future studies, effective training strategies that reduce the negative effects of increased death awareness on counseling students' MCCs can be developed and implemented in counselor training programs. Of course, before that can be accomplished, more research is needed.
Mathematical Creative Thinking Skills Of StudentsJunior High School In Kendari City

The students’ skill to think creatively is one of the main goal given in middle school mathematics. Students’ creative thinking skills have not been as teacher focus to teach mathematics in schools. Students’ mathematical creative thinking skill of students is still low. This study describes an overview of creative thinking skills junior high schools students in Kendari city. Data was collected using a test instrument's skills to think creatively and interviews with students and teachers. The results of the data analysis conclude that the mathematical creative thinking skill of students is still low with an average of 41.19 and a standard deviation of 9.30. The skills of students in aspects of flexibility is very low with an average of just 33.45 , aspects of fluency 39.39, and aspects of elaboration 51.02. Results of interviews with teachers and students show that the use of context and problems creative thinking in mathematics learning is still lacking. The results are less-attractive learning and do not challenge students' thinking skills.
Optic Nerve Crush: Axonal Responses in Wild-Type and bcl-2 Transgenic Mice

Retinal ganglion cells of transgenic mice overexpressing the anti-apoptotic protein Bcl-2 in neurons show a dramatic increase of survival rate after axotomy. We used this experimental system to test the regenerative potentials of central neurons after reduction of nonpermissive environmental factors. Survival of retinal ganglion cells 1 month after intracranial crush of the optic nerve was found to be 100% in adult bcl-2 mice and 44% in matched wild-type (wt) mice. In the optic nerve, and particularly at the crush site, fibers regrowing spontaneously or simply sprouting were absent in both wt and bcl-2 mice. We attempted to stimulate regeneration implanting in the crushed nerves hybridoma cells secreting antibodies that neutralize central myelin proteins, shown to inhibit regeneration (IN-1 antibodies) (Caroni and Schwab, 1988). Again, we found that regeneration of fibers beyond the site of crush was virtually absent in the optic nerves of both wt and bcl-2 mice. However, in bcl-2 animals treated with IN-1 antibodies, fibers showed sprouting in the proximity of the hybridoma implant. These results suggest that neurons overexpressing bcl-2 are capable of surviving axotomy and sprout when faced with an environment in which inhibition of regeneration has been reduced. Nevertheless, extensive regeneration does not occur, possibly because other factors act by preventing it.
Performance Concepts and Performance Theory

SUMMARY This chapter gives an overview of research on individual performance. Individual performance is highly important for an organization as a whole and for the individuals working in it. Performance comprises both a behavioral and an outcome aspect. It is a multi-dimensional and dynamic concept. This chapter presents three perspectives on performance: an individual differences perspective with a focus on individual characteristics as sources for variation in performance; a situational perspective with a focus on situational aspects as facilitators and impediments for performance; and a performance regulation perspective with a focus on the performance process. The chapter describes how current changes in the nature of work such as the focus on continuous learning and proactivity, increase in team work, improved technology, and trends toward globalization have an impact on the performance concept and future performance research.
Impact of document types on the performance of caching algorithms in WWW proxies: a trace driven simulation study

Caching has been recognized as one of the most important techniques to reduce Internet bandwidth in the WWW. Different caching algorithms have been developed to achieve this task. These caching algorithms have been developed for specific contexts and show different performance values depending on their application domains. This is caused by the fact that each caching algorithm rates document characteristics more important than others. In this paper we compare the performance of well-known caching strategies with respect to different document types. For this purpose, we use trace-driven simulation and consider the resulting hit rates as well as the byte hit rates for different extracted traces.
Leaving One Slot Empty: Flit Bubble Flow Control for Torus Cache-Coherent NoCs

Short and long packets co-exist in cache-coherent NoCs. Existing designs for torus networks do not efficiently handle variable-size packets. For deadlock free operations, a design uses two VCs, which negatively affects the router frequency. Some optimizations use one VC. Yet, they regard all packets as maximum-length packets, inefficiently utilizing the precious buffers. We propose flit bubble flow control (FBFC), which maintains one free flit-size buffer slot to avoid deadlock. FBFC uses one VC, and does not treat short packets as long ones. It achieves both high frequency and efficient buffer utilization. FBFC performs 92.8 and 34.2 percent better than LBS and CBS for synthetic traffic in a 4 × 4 torus. The gains increase in larger networks; they are 107.2 and 40.1 percent in an 8 × 8 torus. FBFC achieves an average 13.0 percent speedup over LBS for PARSEC workloads. Our results also show that FBFC is more power efficient than LBS and CBS, and a torus with FBFC is more power efficient than a mesh.

A Low Complexity MPEG Video Decoder with Arbitrary Downscaling Capability

This paper presents some new techniques to implement arbitrary downscaling in decoding MPEG video with very low complexity. The DCT block recomposition method, which was used in resizing static image, is introduced to downscale video in frequency domain with arbitrary factors. New motion compensation based on the block group motion evaluation is proposed to correspond to the downscaled IDCT. Block groups of regular motion and irregular motion are handled respectively to balance the computation cost and picture quality. Analysis indicates the great complexity reduction and experiments show the decoder performance on the MPEG-4 video sequence. These techniques will be beneficial to the video applications on the mobile devices and many other low end embedded systems
A Design of Mutual Exclusion Protocol in Cellular Wireless Networks

The mutual exclusion (MX) paradigm can be used as a building block in many practical problems such as group communication, atomic commitment and replicated data management where the exclusive use of an object might be useful. The problem has been widely studied in the research community since one reason for this wide interest is that many distributed protocols need a mutual exclusion protocol. However, despite its usefulness, to our knowledge there is no work that has been devoted to this problem in a mobile computing environment. In this paper, we describe a solution to the mutual exclusion problem from mobile computing systems. This solution is based on the token-based mutual exclusion algorithm.
Vascular Endothelial Growth Factor Receptors VEGFR-2 and VEGFR-3 Are Localized Primarily to the Vasculature in Human Primary Solid Cancers

Purpose: Vascular endothelial growth factor (VEGF) signaling is key to tumor angiogenesis and is an important target in the development of anticancer drugs. However, VEGF receptor (VEGFR) expression in human cancers, particularly the relative expression of VEGFR-2 and VEGFR-3 in tumor vasculature versus tumor cells, is poorly defined. Experimental Design: VEGFR-2– and VEGFR-3–specific antibodies were identified and used in the immunohistochemical analysis of human primary cancers and normal tissue. The relative vascular localization of both receptors in colorectal and breast cancers was determined by coimmunofluorescence with vascular markers. Results: VEGFR-2 and VEGFR-3 were expressed on vascular endothelium but not on malignant cells in 13 common human solid tumor types (n > 400, bladder, breast, colorectal, head and neck, liver, lung, skin, ovarian, pancreatic, prostate, renal, stomach, and thyroid). The signal intensity of both receptors was significantly greater in vessels associated with malignant colorectal, lung, and breast than adjacent nontumor tissue. In colorectal cancers, VEGFR-2 was expressed on both intratumoral blood and lymphatic vessels, whereas VEGFR-3 was found predominantly on lymphatic vessels. In breast cancers, both receptors were localized to and upregulated on blood vessels. Conclusions: VEGFR-2 and VEGFR-3 are primarily localized to, and significantly upregulated on, tumor vasculature (blood and/or lymphatic) supporting the majority of solid cancers. The primary clinical mechanism of action of VEGF signaling inhibitors is likely to be through the targeting of tumor vessels rather than tumor cells. The upregulation of VEGFR-3 on tumor blood vessels indicates a potential additional antiangiogenic effect for dual VEGFR-2/VEGFR-3–targeted therapy. Clin Cancer Res; 16(14); 3548–61. ©2010 AACR.
Steel hollow columns with an internal profile filled with self-compacting concrete under fire conditions

A detailed experimental and numerical investigation has been performed on the behavior under fire conditions of concrete filled steel hollow section (CFSHS) columns. In this study the internal reinforcement consists of another profile (tube or H section) being embedded with the concrete, and filling is realized by self-compacting concrete (SCC). Ten columns filled with selfcompacting concrete embedding another steel profile have been tested in the Fire Testing Laboratory of the University of Liege, Belgium. Numerical simulations on the thermal and structural behavior of these elements have been made using the non linear finite element software SAFIR developed at the University of Liege. There is a rather good agreement between numerical and experimental results, which can be slightly improved by using the ETC (Explicit Transient Creep) model incorporated in SAFIR. This shows that numerical analyses can predict well the behavior of CFSHS columns under fire conditions. The properties at high temperatures of self-compacting concrete are considered the same as those of ordinary concrete.
Temporal Role for MyD88 in a Model of Brucella-Induced Arthritis and Musculoskeletal Inflammation

ABSTRACT Brucella spp. are facultative intracellular Gram-negative bacteria that cause the zoonotic disease brucellosis, one of the most common global zoonoses. Osteomyelitis, arthritis, and musculoskeletal inflammation are common focal complications of brucellosis in humans; however, wild-type (WT) mice infected systemically with conventional doses of Brucella do not develop these complications. Here we report C57BL/6 WT mice infected via the footpad with 103 to 106 CFU of Brucella spp. display neutrophil and monocyte infiltration of the joint space and surrounding musculoskeletal tissue. Joint inflammation is detectable as early as 1 day postinfection and peaks 1 to 2 weeks later, after which WT mice are able to slowly resolve inflammation. B and T cells were dispensable for the onset of swelling but required for resolution of joint inflammation and infection. At early time points, MyD88−/− mice display decreased joint inflammation, swelling, and proinflammatory cytokine levels relative to WT mice. Subsequently, swelling of MyD88−/− joints surpassed WT joint swelling, and resolution of joint inflammation was prolonged. Joint bacterial loads in MyD88−/− mice were significantly greater than those in WT mice by day 3 postinfection and at all time points thereafter. In addition, MyD88−/− joint inflammatory cytokine levels on day 3 and beyond were similar to WT levels. Collectively these data demonstrate MyD88 signaling mediates early inflammatory responses in the joint but also contributes to subsequent clearance of Brucella and resolution of inflammation. This work also establishes a mouse model for studying Brucella-induced arthritis, musculoskeletal complications, and systemic responses, which will lead to a better understanding of focal complications of brucellosis.
Isolation of Enterobacteriaceae from the Mouth and Potential Association with Malodor

Bad breath is a common phenomenon, usually the result of bacterial metabolism in the oral cavity. It is generally accepted that Gram-negative bacteria are responsible for this problem, largely through degradation of proteinaceous substances. In initial experiments, screening of malodorous isolates following outgrowth of samples obtained from saliva, periodontal pockets, and the tongue dorsum yielded enterobacterial isolates. Clinical studies were conducted to examine the prevalence of such bacteria in four different populations: orthodontic patients, malodor clinic patients, complete-denture wearers, and a healthy young population. The prevalence of Enterobacteriaceae in the oral cavities of the denture-wearing population was very high (48.0%) as compared with the other groups: 27.1% in the malodor clinic patients, 16.4% in the normal population, and 13% among orthodontic patients. Isolates of Klebsiella and Enterobacter emitted foul odors in vitro which resembled bad breath, with concomitant production of volatile sulfides and cadaverine, both compounds related to bad breath. When incubated on a sterile denture, enterobacterial isolates produced typical denture foul odor. Isolates exhibited cell-surface hydrophobic properties when tested for adhesion to acryl and aggregation with ammonium sulphate. The results, taken together, suggest that Klebsiella and related Enterobacteriaceae may play a role in denture malodor.
Magnetization transfer changes in the normal appering white matter precede the appearance of enhancing lesions in patients with multiple sclerosis

Serial monthly magenetization transfer (MT) imaging was performed to evaluate whether a change of the normal appearing white matter (NAWM), which precedes the appearance of enhancing lesions, is seen in patients with multiple sclerosis (MS). Every 4 weeks for 3 months, 10 patients with relapsing‐remitting MS were scanned with a T1‐weighted sequence, 20 minutes after injection with 0.3 mmol/kg gadolinium‐DTPA (Gd‐DTPA). During each of the monthy sessions, MT and dual dual echo scans were also performed before Gd‐DTPA injection. On coregistered images, the same slices but outside any present or future MR abnormality, and in enhancing lesions at the time of their apperance. Forty‐eight new enhancing lesions with no corressponding abnormalities, the mean MTR in NAWM, measured from areas corresponding to future enhancing lesions, was significantly lower than the mean MTR in NAWM outside enhancing areas; the MTR decreased steadily as the time when the enhanced lesion approached. These results suggest that changes in the NAWM of patients with MS occur before lesions becomes evident on conventional MRI scans.
Evaluation of an immunohistochemical test with polyclonal antibodies raised against mycobacteria used in formalin‐fixed tissue compared with mycobacterial specific culture

An immunohistochemical (IH) test (commercially available polyclonal antiserum rabbit anti‐Mycobacterium bovis; DAKO A/S) was used to detect the presence of mycobacteria in 65 formalin‐fixed, paraffin‐embedded tissue blocks from different organs, showing necrotizing caseous granuloma lesions on hematoxylin and eosin sections from 65 patients. These 65 samples were dyed using an acid‐fast fluorescent technique and compared using the immunohistochemical method. Both results were also compared with the mycobacterial cultures. The IH test, compared with the culture, showed a sensitivity (S) of 52%, a specificity (Sp) of 76%, a positive predictive value (PV pos) of 61% and a negative predictive value (PV neg) of 69%. We analyze these data and discuss the possible causes of false‐positive and ‐negative results of the IH test. This rapid test on paraffin embedded tissue seems valuable in the period when waiting for the culture results.
Preventive effects of Turmeric ( Curcuma longa Linn . ) Powder on hepatic steatosis in the rats fed with high fat diet

The aim of the present study was to evaluate the preventive effects of Turmeric (Curcuma Longa Linn.) powder on rat high fat diet-induced hepatic steatosis. For this purpose, male Wistar rats were treated in 4 experimental groups including: 1-healthy control group given standard diet, 2high fat diet group for induction of hepatic steatosis, 3high fat diet plus Clofibrate (320 mg/kg) as positive control, and 4high fat diet plus Turmeric powder (5%) for protection of liver steatosis, at a period of 6 weeks. At the end of experiment, the groups were compared considering serum lipid profile, serum biomarkers of liver tissue injury and liver histopathological changes. The lipid peroxidation product and the activities of antioxidant enzymes were measured as indicators of antioxidation in liver tissue. After 6 weeks, high fat diet caused deleterious metabolic effects, including hypertriglyceridemia, hypercholesterolemia and liver dysfunction. Rats fed high fat diet alone showed increased activities of hepatocellular enzymes in plasma, significant decline in antioxidants, and elevated lipid peroxidation indices in liver. Turmeric treatment significantly reduced elevated markers of liver tissue injury and lipid peroxidation product (MDA), and brought back the liver antioxidants and the over accumulation lipids in serum towards normal. Histopathology of the liver confirmed the changes induced by high fat diet and the hepatoprotective effect of Turmeric powder. The results obtained showed turmeric powder exerts protective effects against hepatic steatosis in rats fed with high fat diet possibly through its antioxidant actions. [Ramin Kaffashi Elahi.
