Lifelong learning and the continued participation of older Norwegian adults in employment

The number of people aged 60 and over across the globe is expected to double by 2050, reaching a share of more than 20 percent of the population total. Governments are therefore taking more and more policy actions to encourage ageing workers to extend their working lives and their employers to retain them. According to the OECD lifelong learning opportunities and inclusive labour markets will be essential to ensuring that workers of all educational backgrounds have the possibility of extending their working lives. This article examines the relationship between adult education completed after age 40 and the subsequent active participation of older adults in employment, using individual register data from Statistics Norway. The results show a substantial effect of upgrading formal education on subsequent labour market participation. Overall effects are quite similar for males and females. Attaining a lower level tertiary degree has the largest impact on labour market participation both for males and females. Completing a secondary education has a strong, long term impact among males. The results suggest that facilitating access to formal education among older workers may be an important contribution to extending working lives.

Correlates of participation in e-book piracy on campus

While the intention and participation in media and software piracy have been widely investigated, little is known concerning the determinants associated with electronic book piracy. With the adoption of e-book reader devices, Internet piracy remains a global concern that impacts multiple stakeholders, including authors, publishers, and libraries. The current study aims to examine the factors associated with electronic book piracy among college students. Results indicate that peer association and perceived risk are significantly linked to one's participation in e-book piracy. However, techniques of neutralization are not statistically significant. Libraries and publishers must educate students and raise awareness about the potential outcomes and risks related to e-book piracy.     

The 2001 Bower Award & prize for achievement in science presented to Paul Baran

The Franklin Institute, Philadelphia, Pennsylvania awarded the 2001 Bower Award and prize to Paul Baran for his efforts to advance our knowledge of physical science or its application for his seminal invention of packet switching—the foundation of modern communications networks and, in particular, the Internet.Simply stated the technology of packet-switching, allows pieces of information to be divided into small packets or “envelopes” of information that are addressed, sent using multiple available routes to a specific destination, then reassembled. This technology—a post office-like system—revolutionized the telecommunications industry. Originally devised during the cold war for a military communications system survivable in the event of nuclear attack, packet switching became the foundation of computer networks including the Internet and truly has altered the world in which we live.     

Multimedia resources designed to support learning from written proofs: an eye-movement study

This paper presents two studies of an intervention designed to help undergraduates comprehend mathematical proofs. The intervention used multimedia resources that presented proofs with audio commentary and visual animations designed to focus attention on logical relationships. In study 1, students studied an e-Proof or a standard written proof and their comprehension was assessed in both immediate and delayed tests; the groups performed similarly at immediate test, but the e-Proof group exhibited poorer retention. Study 2 accounted for this unexpected result by using eye-movement analyses to demonstrate that participants who studied an e-Proof exhibited less processing effort when not listening to the audio commentary. We suggest that the extra support offered by e-Proofs disrupts the processes by which students organise information, and thus restricts the extent to which their new understanding is integrated with existing knowledge. We discuss the implications of these results for evaluating teaching innovations and for supporting proof comprehension.     

Socializing the knowledge transfer problem

A central issue in acquiring knowledge is its appropriate transfer beyond the contexts and contents of first acquisition. In contrast to dominant “common elements” transfer theory, an interpretive perspective is developed, according to which “appropriate transfer” is a concept socioculturally rather than objectively defined. “Elements” perceived by the thinker as common between the current and a prior situation are not given in the nature of things but “read” in terms of the thinker's culturally-influenced categorization system, of problem types. A synthesis of cognitive research findings identifies specific features of thinking-skills instruction effective for promoting transfer. These include learning about and practicing knowledge application in multiple contexts of use, constructively participating in bridging instruction across school and nonschool problem situations, thinking and self-management skills taught within domains, and synergistic integration of the learning of different subjects. Recommendations are made for developing new learning technologies that build upon these conditions for enhancing knowledge transfer.     

审美认同、种族与美国民间音乐

本文运用审美认同的概念来探究音乐类型、社会运动与种族认同之间的关系。在20世纪的美国,其民间音乐在某个时期会破坏黑人与白人之间的绝对边界,而在另一个时期又强化了这种边界。审美认同是艺术类型与社会群体的文化结盟,借助这种结盟,群体就会感觉到某种艺术类型是代表了＂我们的＂或者＂他们的＂艺术、音乐和文学。这样,艺术类型的边界就成了社会的边界。民间音乐颠覆了艺术类型与社会边界的这种常规关系。民间音乐总是一些＂他者＂的文化,或者是种族的、地区的、阶级的文化,或者是民族的文化。在被叫作民间音乐之前,美国的本土音乐更多地体现了种族的完整性而不是其社会性,它是占支配地位的欧洲音乐和主要受非洲音乐影响的音乐相互混合的产物,但是又很好的表现了这两者。在商业唱片时代之前,黑人和白人音乐家们唱着同样的音乐,相互学习歌唱技巧和歌曲,并且共享一个表演的社会空间。民间音乐的概念是由学术精英创造出来的,但直到20世纪30年代到40年代后期,当有组织的左派把它当作一个文化事业时,它对大多数人来说仍然是陌生的。无论是学术精英还是政治活动家都将艺术类型建构成另一种种族化的艺术类型,而商业唱片工业又以＂种族唱片＂和＂山地音乐＂将之双重化。在那个特定的种族极端化的时代,美国的共产主义者和他们的同盟者非常有意识的使用民间音乐作为一种加强种族团结的工具。由于麦卡锡主义的压制,直到20世纪60年代,民间音乐作为种族统一的类型而得到复兴,但迅速被白人化了。为什么民间音乐的复兴与白人有关,我的解释是有三个因素：连续商业化的种族遗产;新左派不能像老左派那样有效地通过文化设施来控制音乐;在某个时候,当黑人努力要进入白人中产阶级青年所抵制的体制中时,一种把民间音乐理解为＂他者＂音乐的文化动力。     

Determination of immunoreactivity of<Emphasis Type="Italic">Plasmodium falciparum</Emphasis> antigens,serum dilutions and biomaterials

Immunoreactivity properties of serum dilutions andPlasmodium falciparum malaria antigens were measured and compared by ELISA technique using different ELISA plates to evaluate the role of antigens and serum dilutions for optimum binding. Also effort has been made to see the effect of reaction surface and material i.e. ELISA plates for binding capacity. Serological properties were estimated by ELISA methods for detection of malaria and determination of immunological characteristics. Three Pf antigens (PfAg) i.e. ring infected erythrocyte surface antigen: AR-1 (RESA), histidine-rich protein 2 antigen (HRP-2) and glycophospholipid antigen (grown and developed Pf antigen from PSJ-M strain): GPL1 have been used for serological testing of human blood samples by Enzyme Link Immunosorbant Assay (ELISA). 1∶100, 1∶1000 and 1∶10000 dilutions of Pf positive and negative serum (50 samples in each group) and 1∶1000 dilution of Pf antigens were used to measure immunoreactive properties by ELISA method. Result of PfAg-serum immunoreactivity study showed that GPL1 has the highest degree of immuno binding reactivity compared to other Pf antigens. HRP-2 and RESA antigens showed no significant difference to each other. Study also found that Costar and Fastec ELISA plates have a better Ag−Ab binding capability compared to immulon and Falcon plates at all dilutions of serum. Serum dilution of 1∶100 showed best binding and reactivity with Pf antigens followed by 1∶1000 and 1∶10000 showed lowest reactivity.
