Design and demonstration of antenna-coupled Schottky diodes in a foundry complementary metal-oxide semiconductor technology for electronic detection of far-infrared radiation
No full textElectronic detection of far-infrared (FIR) radiation up to 9.74 THz is reported in a foundry complementary metal-oxide semiconductor (CMOS) technology. The detectors were fabricated with Schottky-barrier diodes (SBDs) formed in 130-nm CMOS without any process modifications. Direct-antenna matched detectors achieve a measured peak optical responsivity (R V ) of 383 and 25 V/W at 4.92 and 9.74 THz, respectively, near the 5 and 10 THz fundamental frequency of the antennas. A significantly improved R V at 9.74 THz (25× compared to the MOSFET detectors and ~2× compared to the SBD) ensures negligible impact on the system noise-equivalent power (NEP) due to the input-referred noise of the amplifier following the detector. This work also demonstrated that by incorporating the effects of plasma resonance, transit time, and FIR absorption behavior of SiO 2 , as well as the 3D electromagnetic simulations into the SBD model, good agreement between the measurements and simulations can be attained. The detector designed for a 10-THz operation achieves an optical NEP of 1.1 nW/vHz at 9.74 THz in the shot-noise limit, which is comparable to that of commercially available pyro-detectors that are 50 000× larger. © 2019 Author(s).Erik Jonsson School of Engineering and Computer ScienceTexas Analog Center of Excellenc

Democratising the Theatre for Development (TfD) Space through Balancing Power Dynamics: Analysing Practice-Based Experiences from Uganda
No full textThe awareness of power dynamics is fundamental in the implementation of a democratic Theatre for Development (TfD) process. This chapter draws from the author’s practical experiences with TfD practice in Uganda to advocate for effective balancing of the power playing plane. In the first experience, where the author participated as part of the facilitating team of the TfD project aimed at empowering small scale fish farmers, it is argued that if the funders have unrestricted power to dictate the terms of reference for TfD practice, without accommodating the views of the practitioners, it becomes difficult for practitioners to implement a truly democratic process of TfD. In another experience, in Eastern Uganda where the author participated as an invited research observer, it is observed that when the performances of power between the practitioners and the funding bodies are effectively negotiated, the TfD process, depending on the skill and ingenuity of the practitioner yields effective engagement and empowerment. The chapter urges that practitioners should always strive to establish a horizontal plane of working, in dealing with both funders and the communities with which they work. This requires practitioners to assess the impact of their actions, always negotiating and moderating the performance of power in the process
La teoría general de sistemas: La estructura interna de la ciencia Keneth E. Boulding.
No full textEl artículo, cuya traducción se presenta, fue escrito originalmente por uno de los pioneros del desarrollo de la TEORÍA GENERAL DE SISTEMAS y del pensamiento sistémico en general. Luego de unas consideraciones amplias sobre el tema, propone su autor una consideración jerárquica de niveles que va, desde el nivel de los sistemas estáticos, hasta llegar a los complejos niveles de la vida, de la vida humana y las sociedades. Toda esta consideración le sirve a su autor para mostrar los insuficientes desarrollos de las ciencias para abordar los distintos niveles de la realidad empírica y, por supuesto, para destacar la importancia de la T.G.S. para el logro de nuevos marcos de un conocimiento adecuado. Abstract The translation of the article that we are presenting, was written by one of the pioneers in the development of the GENERAL SYSTEMS THEORY and the systemic thought as well. After a wide consideration of the item, his author proposes a hierarchical levels view, being the first one that of the static systems and going through as far as reaching the complex levels of life, human life and societies. Based on this considerations his author shows the low levels reached in the development of sciences to tackle the different levels of the empirical world and also to emphasize the importance of the General Systems Theory for the construction of new frameworks for an adequate knowledge.

"A Symbol of the New African": Drum magazine, popular culture and the formation of black urban subjectivity in 1950s South Africa.
No full textPhDThis thesis examines the emergence of black urban subjectivity in South Africa
during the 1950s, focussing on the ways in which popular American genres were
utilised in the construction of black urban identities that served as a means of
resistance to apartheid. At the centre of this process was Drum magazine:
founded in South Africa in 1951 , it became the largest selling magazine on the
African continent in 1956. Drum's success was due to the way in which it
enabled the relocation of black identity from the "traditional" towards the
"modern'. The 1940s gave rise to widespread migration of black South Africans
from rural to urban areas and this newly urbanised community was seeking
models of black urban identity. Yet the Nationalist government was attempting
to curtail the emergence of a black urban proletariat, which posed a threat to
white political supremacy. Through apartheid legislation black identity was
constructed as essentially tribal and rural. As a means of resisting this, urbanised
black South Africans turned to, and appropriated, readily available forms of
American culture. Drum published Americanised images and stories: gangsters,
black detectives, black comic heroes, and pulp romances. This popular material
appeared alongside some of the finest investigative journalism ever published.
While Drum magazine is widely acknowledged as having provided a platform
for the emergence of black South African writing in English, its popular content
has been dismissed by critics as apolitical escapism, imitation and capitulation to
American culture. This thesis challenges the dismissal of the popular that has
dominated analyses of Drum since the 1960s, arguing that such a position denies
the agency of local writers and audiences. My analysis reveals that American
forms were adopted in critically discerning ways and chosen for their ability to
convey local meaning and create positions from which to resist aparthei

No full textLiquidity needs and vulnerability to financial udnerdevelopment
Get PDFThe author provides evidence of a causal and economically important effect of financial development on volatility. In contrast to the existing literature, the identification strategy is based on the differences in sensitivities to financial conditions across industries. The results show that sectors with larger liquidity needs are more volatile and experience deeper crises in financially underdeveloped countries. At the macroeconomic level, the results suggest that changes in financial development can generate important differences in aggregate volatility. The author also finds that financially underdeveloped countries partially protect themselves from volatility by concentrating less output in sectors with large liquidity needs. Nevertheless, this insulation mechanism seems to be insufficient to reverse the effects of financial underdevelopment on within-sector volatility. Finally, the author provides new evidence that: 1) Financial development affects volatility mainly through the intensive margin (output per firm). 2) Both the quality of information generated by firms, and the development of financial intermediaries have independent effects on sectoral volatility. 3) The development of financial intermediaries is more important than the development of equity markets for the reduction of volatility.Payment Systems&Infrastructure,Economic Theory&Research,Markets and Market Access,Fiscal&Monetary Policy,Financial Crisis Management&Restructuring,Economic Theory&Research,Financial Crisis Management&Restructuring,Fiscal&Monetary Policy,Development Economics&Aid Effectiveness,Markets and Market Access
Dilemmas in involved research
No full textPrezentowane opracowanie składa się z trzech zasadniczych części. W pierwszej
części autorka ukazuje swoją dotychczasową drogę badawczą nad życiem jednej
ze wspólnot wirtualnych. Prezentuje obszary swoich zainteresowań badawczych,
którymi stały się różnorodne aspekty funkcjonowania wspólnot wirtualnych – m.in.
aspekt komunikacyjny, poradniczy, obyczajowy oraz taki, który związany jest z poczuciem
tożsamości lokalnej. W drugiej części autorka dzieli się dylematami, które
towarzyszą jej podczas prowadzenia owych badań. Dylematy dotyczą etycznego
aspektu zaangażowanych badań uczestniczących. W trzeciej części opracowania
zaprezentowany został specyficzny sposób prowadzenia badań. Metodologiczną
inspiracją dla autorki stała się koncepcja badań emicznych autorstwa Kenetha Lee
Pike’a. Zasadnicze cechy tej strategii badawczej to: badanie kultur „od wewnątrz”,
wykorzystywanie przez badacza płaszczyzny uczestnika kultury, stosowanie obserwacji
uczestniczącej (wewnętrznej), odwoływanie się do pojęć członków, a przede
wszystkim – utrzymywanie zaangażowania emocjonalnego przez badacza. Ostatecznie
wszystkie te argumenty okazały się być bardzo pomocne i stały się metodologicznym
wsparciem w prowadzonych przez autorkę badaniachThis paper consists of three main parts. In the first part the author describes the progress
of her research on the life of a selected virtual community. She presents the areas of interest
to her, which include various aspects of virtual community functioning – such
as the communicative, counseling or social aspect, as well as the one associated with
the sense of local identity. In the second part the author describes the dilemmas she
faces in the course of her research. They refer to the ethical aspect of involved research.
The third part contains a description of a particular research procedure. The concept
of emic research developed by Keneth Lee Pike constitutes the methodological inspiration
for the author. The essential features of this research strategy include: the study
of cultures “from the inside”, the use of the culture participant plane by the researcher,
the use of participant internal observation, referring to the terms of members, and
most of all – maintaining an emotional involvement by the researcher. Eventually, all
these elements have proved to be very helpful and provided a methodological support
in the research conducted by the author
