The social inclusion of youth is addressed from the perspective of goal-directed action in order to understand and foster it effectively. Conceptualized from the perspective of contextual action theory (CAT), the specific understanding of action as levels, perspectives and systems provides the basis to unpack the complexity of human action. One pertinent action system is identified as project. It refers to a series of actions over time with the same goal. Using this understanding, the social inclusion of youth is described though the joint actions and projects between youth and non-familial adults. These joint actions and projects include advocating for youth, providing instrumental knowledge and encouraging community involvement and civil engagement. CAT is also used to conceptualize and conduct research on the social inclusion of youth. Specifically, the action project method was used to describe the joint projects of both youth with disability and immigrant youth as these projects involved the youth’s social inclusion.

AT the Conference at Folkestone of the London and Home Counties Branch of the Library Association, Mr. Jast gave one more example of his old fire and vigour in a paper which he entitled Publishers and Librarians. No doubt in other pages than ours the text will be given in full. Here, in summary, we may say that he dealt with some of the needs of librarians and readers for well‐produced editions of good books which for some reason were obtainable only in double‐columned small type or otherwise almost unreadable or at any rate unattractive form. He instanced Disraeli's Curiosities of Literature. He urged that if a sufficient number of public and other librarians represented this want to publishers, promising that the libraries would support such an edition, it was unlikely that the request would be ignored. A further suggestion arose from the established fact that in the welter of editions of certain books many were ill‐produced and unworthy to be placed in the hands of unsuspecting bookbuyers. Robinson Crusoe was a case in point, and as many parents desired their sons to read this they were often persuaded to buy editions which were unsuitable. Here he made a suggestion which is entirely practicable: that the Library Association should examine all of the common classics for form and for textual accuracy—a feature in which he alleged that some were deficient—and fix on suitable editions, allowing the publisher to add to their title‐pages “approved by the Library Association.” We seize upon this point first because there is nothing Utopian about it. It is a work that ought to be done.

This paper aims to first apply more advanced anisotropic yield criterions as Yld91 and Yld2004 to spherical indentation simulations, and investigate plastic anisotropy identified from indentation simulations following different yield criterions (Hill48, Yld91, Yld2004) to discover laws. It also aims to compare the difference in plastic anisotropy identified from indentation on three yield criterions and evaluate the applicability of plastic anisotropy.

This paper uses indentation simulations on different yield criterions to identify plastic anisotropy. First, the trust-region techniques based on the nonlinear least-squares method are used to determine anisotropy coefficients of Yld91 and Yld2004. Then, Yld91 and Yld2004 are implemented into ABAQUS software using user-defined material (UMAT) subroutines with the proposed universal structure. Finally, through considering comprehensively the key factors, the locations of the optimal data acquisition points in indentation simulations on different yield criterions are determined. And, the identified stress–strain curves are compared with experimental data.

This paper discovers that indentation on Yld2004 is able to fully identify difference in equivalent plastic strain between 0° and 90° directions when indentation depth h_t is relatively smaller. And, this research demonstrates conclusively that plastic anisotropy identified from indentation on Yld2004 and Yld91 is more applicable at larger strains than that on Hill48, and that on Yld2004 is more applicable than that on Yld91, overall. In addition, the method on the determination of the locations of the optimal data acquisition points is demonstrated to be also valid for anisotropic material.

This paper first investigates plastic anisotropic properties and laws identified from indentation simulations following more advanced anisotropic yield criterions and provides reference for later research.

IN mid 1963 the Guided Weapons Division of the British Aircraft Corporation was charged with the problem of producing a nose radome for the Concorde supersonic transport.

WITH this issue we are commencing the twenty‐seventh year of our career as an independent Library Journal and trust that we shall carry on the tradition of our illustrious founder and continue to criticise or praise without fear or favour. During the past twelve months our editorial staff has successfully produced special numbers dealing with Bookbinding, Book Selection, Children's Departments, Classification, and Colonial Libraries. Judging by the correspondence we have received, our efforts have been greatly appreciated by the majority of our readers. Naturally we have not pleased everybody and we have even been dubbed the “little contemporary” in some quarters. However, we can point to an unbroken record of twenty‐six years' endeavour to serve the library profession and we ourselves are justly proud of the contemptible “little contemporary” that did not cease to appear even during the darkest hours of the dread war period.

Vaping has become a prominent public health problem that has impacted young adults. The purpose of this study is to empirically examine the effects of different intrinsic and extrinsic motivations on young adults’ realization of excessive vaping and their intention to quit vaping.

A survey was used to collect data from 232 young vapers (primarily Generation Z and Millennials) to test the hypothesized relationships using a covariance-based structural equation model.

The findings of this study suggest that “realization of excessive vaping” is negatively associated with “sensation seeking” and positively associated with “deal proneness,” “environmental cues” and “negative repercussion.” The “intention to quit vaping” is negatively associated with “marketing cues” and positively associated with “alternative to smoking” and “environmental cues.” Finally, the “realization of excessive vaping” is positively associated with “intention to quit vaping.”

This study takes a two-dimensional approach to understand the complex motivations behind a relatively new addictive behavior – vaping. It contributes to the literature of addictive behavior, social cognitive theory and theory of planned behavior. Further, it has important implications for public policy and the marketing of addictive products to youths.
