The Role of the Individual – A Key to Learning in Preparedness Organizations

A well functioning societal response to crises is benefited by individuals having adequate skills and knowledge. From a municipal perspective this requires the creation of a learning organization. The objective of this study is to determine whether individual municipal employees, who have the responsibility for preparedness planning, reason and act in ways that promote learning about crises and preparedness issues throughout the municipal organization. Analysis of interviews with preparedness planners in six Swedish municipalities on their strategies for preparedness planning, reveal that preparedness planning too often becomes a demarcated activity, restricted to not more than a handful of individuals. This study indicates that one reason for why the preparedness work becomes demarcated is that individuals central to the preparedness planning are not taking on roles for acting in ways that are required in order for a learning organization to be established.     

Diagnostic validity of the Luria-Nebraska Neuropsychological Battery—Children's Revision.

Compared the diagnostic validity of the Luria-Nebraska Neuropsychological Battery—Children's Revision (LNNB—C) and the Wechsler Intelligence Scale for Children—Revised (WISC—R) for 96 8–12 yr olds in 1 of 3 diagnostic groups: neurological, psychiatric, and normal controls. Interrater reliability was demonstrated. Separate stepwise discriminant analyses using 6 variables (subtest scores) selected by each test correctly classified 81% (LNNB—C) and 85% (WISC—R) of the psychiatric and neurological groups. No clear incremental validity for the use of the LNNB—C over the WISC—R was demonstrated. (23 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The role of long memory in hedging effectiveness

A joint fractionally integrated, error-correction and multivariate GARCH (FIEC-BEKK) approach is applied to investigate hedging effectiveness using daily data 1995-2005. The findings reveal the proxied error-correction term has a long memory component that theoretically should affect hedging effectiveness. When the FIEC model empirical conditions are satisfied, the FIEC-BEKK hedging strategy outperforms the OLS benchmark out of sample in terms of both variance reduction and hedger utility. A bootstrap exercise indicates that the variance reduction is statistically significant.     

Effects of Printed Circuit Board Transmission Lines and Loading on Gate Performance

Experimental measurements were conducted on a typical high-speed logic gate (AS04) driving a similar gate(s) as a load(s) and connected via a printed circuit board transmission line. This simple system was used to investigate waveform characteristics. The results show that rise and fall times are a function of position and are linearly dependent on fanout. The gate and line parameters are estimated from these measurements using both lumped and distributed models of the loads.     

Resource pool management: Reactive versus proactive or let’s be friends

The consolidation of multiple workloads and servers enables the efficient use of server and power resources in shared resource pools. We employ a trace-based workload placement controller that uses historical information to periodically and proactively reassign workloads to servers subject to their quality of service objectives. A reactive migration controller is introduced that detects server overload and underload conditions. It initiates the migration of workloads when the demand for resources exceeds supply. Furthermore, it dynamically adds and removes servers to maintain a balance of supply and demand for capacity while minimizing power usage. A host load simulation environment is used to evaluate several different management policies for the controllers in a time effective manner. A case study involving three months of data for 138 SAP applications compares three integrated controller approaches with the use of each controller separately. The study considers trade-offs between: (i) required capacity and power usage, (ii) resource access quality of service for CPU and memory resources, and (iii) the number of migrations. Our study sheds light on the question of whether a reactive controller or proactive workload placement controller alone is adequate for resource pool management. The results show that the most tightly integrated controller approach offers the best results in terms of capacity and quality but requires more migrations per hour than the other strategies.     

Correlation of omega-3 levels in serum phospholipid from 2053 human blood samples with key fatty acid ratios

Background  

This research was conducted to explore the relationships between the levels of omega-3 fatty acids in serum phospholipid and key fatty acid ratios including potential cut-offs for risk factor assessment with respect to coronary heart disease and fatal ischemic heart disease.     

Brian Mullen (1955-2006).

Presents an obituary for Brian Mullen. In a field that values empirical precedent and established paradigms, Brian Mullen's career was one of passion and originality. He was motivated by pure intellectual curiosity; the recognition he received for his pioneering work in archival methodology, meta-analysis, and group processes and relations was secondary. His contributions to the field of social psychology were unique and will be enduring. His 1985 book with Robert Rosenthal, BASIC Meta-Analysis: Procedures and Programs, is a classic. In 2006, he was identified as the 15th most cited scholar in social psychology textbooks. Brian died of cancer on May 4, 2006. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The cholinergic agent physostigmine enhances short-term-memory-based performance in the developing rat.

There are age-related differences in the rat's short-term memory processes. Rats 24–25 days old are 90% correct when the delay interval separating the forced run and choice run of a trial is either 10 or 30 s, but they perform at chance when the delay interval is 60 s. In contrast, the choice performance of 30-day-old rats remains constant across all delay intervals. It is reported that the cholinergic agent physostigmine dramatically improved the short-term-memory-based performance of rats 24–25 days old such that they displayed no loss in choice accuracy even when the delay interval was 60 s. No such enhanced performance was seen in rats treated with neostigmine, a peripherally acting anticholinesterase. The results support the hypothesis that postnatal maturational differences in central cholinergic systems may contribute to age-related differences in short-term memory.

降低热预算引起污染

设备制造商和晶圆厂在运营上一直在寻找降低热预算的方法，这样可以提高生产率，降低原材料、设备以及能源的消耗。例如：对于某些外延工艺，工程人员设法在降低反应温度的同时，满足薄膜性能的苛刻要求。这意味着外延工艺将在更快的过程转换中完成，而不是像很多年前，必须将反应腔温度稳定在1000℃以上。然而，随着反应温度的降低，工程人员也发现，在反应腔、压力容器，晶圆输送盒，甚至晶圆上出现了以前没有过的污染物。因此，用户需要开发出可以密切监控污染物的检测方法。     

A test of subliminal symbiotic activation as a means of alleviating depression.

Thirty-six depressive subjects were randomly assigned to one of three treatment groups. Group 1 subjects received 60 subliminal presentations of a slide of two figures and the words MOMMY AND I ARE ONE for male subjects and DADDY AND I ARE ONE for female subjects. Group 2 subjects received 60 subliminal slide presentations of a single figure with the words PEOPLE ARE WALKING. Group 3 subjects did not receive a slide. A pretest and posttest Beck Depression Inventory was administered to assess depression increase or decrease. The "subliminal" therapy was carried out over four different sessions. The data show that Group 1 subjects significantly reduced depression scores from pretest to posttest, whereas the subjects in Groups 2 and 3 did not reduce depression scores. Discussion is centered on comparisons of the data with past findings. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
