Virtual vs. Standard Strike: An Experiment
Full text linkIn this paper we compare - in the laboratory - stoppage and virtual strike. Our experiment confirms that higher wages offered by an employer lead to considerably more costly effort provision. The number of strikes, the level of efforts and average total payoffs are higher under virtual strike than under standard strike. However, when standard strike is associated with reciprocal externalities, it induces higher effort levels, higher payoffs and an extremely reduced number of strikes than virtual strike. It is unclear whether this behavior re?ects reciprocity or other forms of social preferences. However our results might explain why standard strikes rather than virtual ones are generally adopted by workers.virtual strike, cooperation, reciprocity, fairness, experiments
Nahuatl in the Huasteca Hidalguense : a case study in the sociology of language
No full textThis thesis examines the vitality of Hidalgo Nahuatl (HN) in the
communities of Jaltocan, Panacaxtlan, Santa Cruz, Santa Teresa
and Zohuala in the Huasteca Hidalguense, Mexico.
The research, conducted in Mexico and St. Andrews University
from 1976-1982, applies an analysis of HN within the framework of
the Sociology of Language and Dependency Theory, thereby using a
multi-disciplinary approach. Through an investigation of the historical,
social, cultural and economic factors related to HN, the
latter is embedded in its reality.
HN is shown to be originally a language of dependency and oppression,
supported by a long mestizo tradition of "caciquismo". It is
demonstrated that an increasing number of Spanish (S) monolinguals,
together with other socio-economic factors, is encouraging Nahuas
to bilingualize and S:: =A. is fast becoming the new language of dependency.
The Hidalgo Nahuas possess practical reasons for the acquisition
of S., these being to solve their daily problems - especially
land tenancy -, to communicate with the mestizo out-group and to
undertake trading with non-HN speakers. However, the Nahuas are
not surrendering their native language as they bilingualize, but
rather, tend to limit its usage to native Nahua contexts and speakers.
HN has become important to the Nahuas in order to demonstrate
their ethnic identity and territoriality.
The introduction of government projects to the communities, such as
the Castellanizacion project or bilingual-bicultural education, are
shown to be theoretically bilingual in approach, but fail to take
into account sufficiently the regional Indian language in the praxis.
The stable maintenance of HN is highlighted by statistical results
from the word-count of recorded texts, documents and publications
and the range of morphological phenomena affecting S. words
in HN is described with examples from the Corpus.
The linguistic interference from S. in HN is located within Dependency
Theory and this author suggests the use of the term dependency
word rather than loan word and dependency language, thus implying
a diachronic sociological process which is reflected in HN.
Extended Texts are offered as evidence of the linguistic standard
of HN and attitudes of Nahuas towards their language are presented.
The final conclusion is that modern HN is a viable, vital and
functional language at the time of undertaking this research and
demonstrates a frequent usage by a large number of speakers. HN
has still not entered into:. -avital process of language death, as
is the case in other Nahuatl-speaking regions of Mexico, and is
still being maintained, particularly at community level, by adults
and children alike
BMOL(Hn) spaces and Carleson measures for Schrödinger operators
No full textAbstractLet L=−ΔHn+V be a Schrödinger operator on the Heisenberg group Hn, where ΔHn is the sub-Laplacian and the nonnegative potential V belongs to the reverse Hölder class BQ2. Here Q is the homogeneous dimension of Hn. In this article we investigate the dual space of the Hardy-type space HL1(Hn) associated with the Schrödinger operator L, which is a kind of BMO-type space BMOL(Hn) defined by means of a revised sharp function related to the potential V. We give the Fefferman–Stein type decomposition of BMOL-functions with respect to the (adjoint) Riesz transforms R˜jL for L, and characterize BMOL(Hn) in terms of the Carleson measure. We also establish the BMOL-boundedness of some operators, such as the (adjoint) Riesz transforms R˜jL, the Littlewood–Paley function sQL, the Lusin area integral SQL, the Hardy–Littlewood maximal function, and the semigroup maximal function. All results hold for stratified groups as well
The Weight and Hopcount of the Shortest Path in the Complete Graph with Exponential Weights
No full textBoth the hopcount HN (the number of links) and the weight WN (the sum of the weights on links) of the shortest path between two arbitrary nodes in the complete graph KN with i.i.d. exponential link weights is computed. We consider the joint distribution of the pair (HN,WN) and derive, after proper scaling, the joint limiting distribution. One of the results is that HN and WN, properly scaled, are asymptotically independent.Delft Institute of Applied MathematicsElectrical Engineering, Mathematics and Computer Scienc
FOURIER TRANSFORM FAR-INFRARED SPECTROSCOPY OF HN ON THE AILES BEAMLINE OF SYNCHROTRON SOLEIL
No full textAuthor Institution: Ligne AILES, Synchrotron SOLEIL, L'Orme des Merisiers Saint-Aubin, 91192 Gif sur Yvette Cedex - FranceWe report the pure rotation spectrum of HN measured by Fourier Transform (FT) absorption spectroscopy in the 20-40 cm spectral range. The cations are produced in a liquid nitrogen cooled hollow cathode discharge cell developed on the AILES beamline of synchrotron SOLEIL. The set-up was optimized by recording rotation-vibration spectra of H( band centered at 2521 cm), HN ( band centered at 3234 cm) and HCO( band centered at 3089 cm). Many rotation-vibration lines have been assigned for each ion and 5 pure rotational transitions have been detected for HN. These results demonstrate the feasibility to record far-infrared (far-IR) spectra of cationic species using FT broad band spectroscopy associated to the bright synchrotron radiation continuum as an alternative to laser-based frequency tunable techniques. In the presentation, we will describe the experimental set-up, the results obtained and the perspectives of this preliminary work which will rely on the exploitation of intense Coherent Synchrotron Radiation (CSR)

He is known as the leading figure of the religious person who is respected by various religious figures (Islam, Christian, Hindu, Buddha and Kaharingan). The charismatic muslim scholar not only as the Islam religious figure (as the management in the organisation NU and the MUI, tutor and also a tasawuf and deity/teacher as well as was active in the governments politik and author of some books especially the book of tasawuf knowledge and the deity, his reference is made as material of the tasawuf teaching and the deity inside and overseas, he got the degree of honour as the Doctor of Honoris Causa (HC), because of his writing, various of the religious figures and the senior officials in Central Kalimantan often ask for his advice and blessing to him
Comics as Covid-19 response: Visualizing the experience of videoconferencing with aging relatives
Full text linkThis article and accompanying comic strip/poster explore the narrative research affordances of comics in response to the COVID-19 pandemic. We explore the concept of empathy from a self-conscious auto-ethnographic perspective, producing a co-designed one-page comic out of the experience. The comic depicts two middle-aged brothers in conversation with their mother and father on FaceTime. After initial confusion and mild struggle with the technology, the parents adjust to the communication situation and begin to enjoy communicating with their sons, who make light of the situation. The aim of the comic is to persuade readers that it is better to struggle with and accommodate to technology than to risk visiting elderly relatives who are particularly susceptible to COVID 19. Meanwhile, the reflection on the comic discusses the thought processes and materials that went into creating it and implications of those
