Personality and job performance: Test of the mediating effects of motivation among sales representatives.

Research shows consistent relations between personality and job performance. In this study the authors develop and test a model of job performance that examines the mediating effects of cognitive-motivational work orientations on the relationships between personality traits and performance in a sales job (N=164). Covariance structural analyses revealed proximal motivational variables to be influential mechanisms through which distal personality traits affect job performance. Specifically, striving for status and accomplishment mediate the effects of Extraversion and Conscientiousness on ratings of sales performance. Although Agreeableness was related to striving for communion, neither Agreeableness nor communion striving was related to success in this sales job. The importance of the proposed motivational orientations model is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Constructing a typology of H2 in cities and regions: An international review

This paper primarily develops a seven-fold conceptual typology of place-based hydrogen initiatives. Through an international review of place-based hydrogen initiatives we reveal a plethora of projects, demonstrations, test-beds, ambitions and expectations at a wide range of spatial scales. We ask whether there is anything distinctive about how these different spatial scales attempt to develop the hydrogen economy. In particular, we seek to identify whether patterns emerge around the social interests involved at different scales of activity and the degree to which hydrogen links to different place-based agendas—political and resource autonomy, economy and employment. The paper addresses these questions and draws out a series of three key conclusions. First, there is wide ranging and significant diversity in the motivations for cities and regions to become involved in hydrogen economy developments—wider than conventional energy policy objectives. Second, there are still significant overlaps between different scales of action. Third, there is a tension between the more bounded concepts of using hydrogen to build self-reliance at a particular scale and those initiatives oriented around developing a more systemic technological system which is rolled out elsewhere. Finally, we argue that a key issue for further research is in understanding the social interests and institutions that attempt to both learn from across these activities at different scales and provide some sense of coordinated action between them. In our review the role of corporates—rather than national government—seems to be critical to such attempt to provide coordination across places and needs to be the focus of further research.     

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.     

嵌入存储器时需谨慎行事

技术在进步，时代在前进。移动 式电子产品的设计人员早己不再依靠购买现成的芯片来组装系统了。现在，许许多多的移动装置制造商都在自己开发芯片。实际上他们只是开发自己的网表，而芯片的实际制造则完全交给半导体制造商去进行。随着微电子技术的进步，芯片中可以集成的线路，远远地超过逻辑线路的需要，还可以将存储器，模拟线路集成到同一芯片中。 将存储器集成到逻辑线路中己经是寻常之事，再增加一些模拟功能的线路，就可以初步实现长期追求的目标—一实现系统集成芯片。但是，在决定是否采用嵌入式存储器，嵌入什么样的存储器，以及…     

Aerosol-jet-printed, high-speed, flexible thin-film transistor made using single-walled carbon nanotube solution

A high-purity, surfactant-free and stable SWCNT aqueous solution was prepared using a series of chemical and physical processes. The SWCNT solution has a very limited amount of carbonaceous impurities, if any, and a total metal content of well below 500 ppb. It is stable for months without the addition of surfactant. Such SWCNT aqueous solution enables ink-jet printing of the entire fast, flexible SWCNT-based field-effect thin-film transistor (FE-TFT) at room temperature without the engagement of any traditional dry or wet chemical processes used for fabricating silicon-based transistors. High-speed SWCNT-based flexible FE-TFTs were printed using Aerosol Jet^® printing technology. The printed flexible FE-TFTs were characterized to have a current ON-OFF ratio of greater than 130 with an operation frequency of greater than 5 GHz.     

Replacing the Equations of Fano and Fisher for Cased Charge Blast Equivalence – I Ductile Casings

The initial velocity of casing fragments from bombs, shells etc. was first calculated by R. W. Gurney in 1943 [1]. Subsequent to this derivation by Gurney, which was based on a reasonable simplification of the case and gas dynamics, his wartime co‐worker, U. Fano [2], claimed to have calculated the proportion of kinetic energy remaining with the explosive gases following energy partition with the casing. This paper shows that both Fano’s equation for cased charge blast equivalence and a further derivation by Fisher in 1953 [3], based on Fano’s, are in fact inconsistent with Gurney’s reasonable physical model. Neither of these two reports has ever been the subject of independent peer‐review, despite having been extensively cited. This paper identifies the error made by Fano and copied by Fisher and draws attention to an alternate equation recently published by the author which gives similar predictions to that of Fisher, while being consistent with Gurney’s original derivation. Also, this paper establishes for the first time that the use of such equations for cased charge blast impulse equivalence is valid.     

Antioxidant potential and content of phenolic compounds in extracts of twelve selected Malaysian commercial wood species

This study was performed to investigate the antioxidant values of twelve selected Malaysian wood species. Bark and heartwood were extracted with toluene: industrial methylated spirit (Tol: IMS) and evaluated for antioxidant activity. Folin–Ciocalteu reagent was used to determine the total antioxidant activity and total phenols of plant extracts. Free radical scavenging activity was evaluated using 2,2-dipheny-2-picrylhydrazyl (DPPH). Extractive yields, antioxidant activity and total phenolic content varied among wood species. N. heimii had the highest extractive yields (23.50 and 9.16 %), antioxidant (93.60 and 83.78 %) and total phenolic content (29.11 and 24.11 mgGAE/g) for bark and heartwood, respectively. The results provided promising evidence that those tropical timbers may be useful as potential sources of natural antioxidants and could be used as drug formulations.
