Tuned LNA for RFICs using boot-strapped inductor
No full textIn this paper, the principle of operation of a new type of active inductor and its application to a tuned LNA are described. The design is optimized at 1.8 GHz. An integrated transformer in connection with a current amplifier realizes a "boot-strapped" inductor with a L x Q factor never obtained before at this frequency. This way a selective LNA with a 60 MHz bandwidth, corresponding to a Q of 30, was designed. The circuit exhibits a matched noise figure of 1.8 dB with 25.5 dB transducer power gain while dissipating 20.7 mW from a 3 V power supply

The Reshoring of Business Services:Reaction to Failure or Persistent Strategy?
Full text linkThis paper investigates whether reshoring of business services is the result of company response to performance shortcomings of the initiative offshored or instead is motivated by persisting with original offshoring strategy (disintegration advantages, accessing new markets and cost-saving), regardless of offshoring performance. Our empirical analysis, based on data from the Offshoring Research Network, shows that both arguments hold. Moreover, when offshoring had been motivated by accessing to new markets and its performance is unsatisfactory, companies are likely to relocate. However, unsatisfactory performance of activities offshored for efficiency reasons or search of talent, do not necessarily lead companies to relocate elsewhere
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Inertial vs. mindful repetition of previous entry mode choices: do firms always learn from experience?
Full text linkExperience, meant as the repetition of the same action, is considered a predictor of the entry mode choice in foreign markets because it allows reducing uncertainty. However, repetition does not necessarily increase the expected performance, depending on the learning stemming from previous experiences. Focusing on offshoring decisions, namely the choice between captive and outsourcing entry mode, we distinguish between the inertial repetition of routines vs. the mindful repetition of previous entry modes (where the company distinguishes and internalizes the outcomes of the past offshoring initiatives associated to the entry choices). We claim that: (i) the latter leads to higher growth perspectives for the focal offshoring initiative, and; (ii) learning is higher when repetition concerns captive entry modes. Our empirical analysis, run on 410 companies’ offshoring decisions undertaken from 2006 to 2011, confirms our expectation
Complementing the reshoring of manufacturing activities: the relocation of business functions
No full textVariations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
