  1. 1. Enterprise Social Media in Project-based Knowledge Work : A contextualized view through the lens of activity theory

    Författare :Emma Forsgren; Pam McKenzie; Högskolan i Borås; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; enterprise social media; information sharing; activity theory; case study; Library and Information Science; Biblioteks- och informationsvetenskap;

    Sammanfattning : Project-based knowledge work is characterised by decentralised and dynamic team-based structures, different from the tradi­tional, bureaucratic organisation. Arguably, this flexible and collaborative work setting could benefit from enterprise social media, which helps facilitate how people connect, collaborate and share information across organisational boundaries.

  3. 2. The theory of mitigating risk : Information literacy and language-learning in transition

    Författare :Alison Hicks; Pam McKenzie; Högskolan i Borås; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Library and Information Science; Biblioteks- och informationsvetenskap;

    Sammanfattning : This qualitative study explores the information literacy practices of students who were learning a language overseas as part of their undergraduate degree. Constructivist grounded theory and situational analysis were used to examine the information activities of 26 English-speakers from Australia, Canada, the United States and the United Kingdom.

  4. 3. Mechanisms of insulin signaling and the role of caveolae

    Författare :Santiago Parpal; Pam Fredman; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Insulin regulates metabolic as well as mitogenic processes in target cells, involving a large number of mediators of signal transduction. In its role as a growth factor, insulin stimulates cell growth, in a process we demonstrate requires the participation of the Raf-1 kinase. LÄS MER

  5. 4. Short-range Optical Communications using 4-PAM

    Författare :Tamas Lengyel; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data communication; vertical cavity surface emitting lasers; 4-PAM; IM DD; NRZ OOK; optical interconnects; short-range fiber optic links; multimode fiber; inter-symbol interference; intensity modulation;

    Sammanfattning : As the demand for ever higher throughput short-range optical links is growing, research and industry has shown increased interest in multilevel modulation formats, such as the four leveled pulse amplitude modulation, referred to as 4-PAM. As on-off keying persists to be the choice for low latency applications, such as high performance computing, datacenter operators see 4-PAM as the next format to succeed current OOK-based optical interconnects.

  7. 5. Multilevel Modulation and Transmission in VCSEL-based Short-range Fiber Optic Links

    Författare :Tamas Lengyel; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IM DD; NRZ OOK; intensity modulation; 3-PAM; inter-symbol interference; Data communication; multimode fiber; vertical cavity surface emitting lasers; 4-PAM; optical interconnects; short-range fiber optic links;

    Sammanfattning : As the demand for ever higher throughput short-range optical links is growing, research and industry associations have shown increased interest in multilevel modulation formats, such as the four leveled pulse amplitude modulation, referred to as 4-PAM. As on-off keying (OOK) persists to be the choice for low latency applications, for example high performance computing, datacenter operators see 4-PAM as the next format to succeed current OOK-based optical interconnects.
