葫芦门式起重机主梁焊缝检验及其质量评定

主梁不仅是葫芦门式起重机的主体部件,而且还是主要的受力构件,因此主梁的质量直接决定着整机的寿命,而主梁焊缝质量又是决定主梁这一焊接结构件的质量关键所在。所以从保证安全和质量的角度出发,对主梁焊缝的宏观和微观检验必不可少,且根据检验结果做出准确可信的质量评定是十分重要的。实践结果表明,在检验中不仅要按照标准的要求而且还要加以消化,才能把握好对主梁焊缝检验的尺度,直至给出正确的评定,进而达到保证起重机整机制造质量的目的。

The Influence of Consumer Degree of Knowledge on Consumer Behavior: The Case of Spanish Olive Oil

This article analyses the influence of perceived quality measured across intrinsic and extrinsic attributes on satisfaction and consumer loyalty for a traditional food product as with PDO (Protected Designation of Origin) olive oil “Aceite del Bajo Aragón.” In addition, the article highlights the influence of consumer's degree of knowledge on these relationships. The results suggest that the main drivers to explain consumers' satisfaction and loyalty are the perceived quality of the intrinsic attributes (color, appearance, flavor, etc.). However, when consumers are classified attending to their degree of knowledge the main explanatory variable of satisfaction and loyalty of the more experienced consumers are the extrinsic attributes of the product (brand name, place of origin, images associated to the product, etc.). These findings allow us to develop important managerial implications for building a brand image for a PDO.     

Profiling Computer Predispositions

ABSTRACT

An exploratory study was undertaken to measure undergraduate student attitudes toward computers. A revised version of the Bath County Computer Scale (BCCAS) developed by George Bear, Herbert Richards, and Paul Lancaster was administered to a proportionality sample of 310 undergraduate students whose demographic make-up was very dissimilar to those who had participated in the original BCCAS instrument validation study.

A thirty-six item instrument was personally administered to 310 learners pursuing undergraduate studies, yielding a total of 11,160 individual responses. The data so obtained were subjected to several statistical tests of significance such as ANOVA. Through cross-classification numerous tables were generated and analyzed.

The findings indicate that demographic variables such as gender, status, GPA average, major, prior computer experience and anticipated future use of computers show significant differences in how Students feel about computers.
