Optimal Dynamic Auctions Are Virtual Welfare Maximizers
Authors: Mirrokni Vahab , Leme Renato Paes , Tang Pingzhong , Zuo Song 
Published: September 2019

We are interested in the setting where a seller sells sequentially arriving items, one per period, via a dynamic auction. At the beginning of each period, each buyer draws a private valuation for the item to be sold in that period and this valuation is independent across buyers and periods. The auction can be dynamic in the sense that the auction at period t can be conditional on the bids in that period and all previous periods, subject to certain appropriately defined incentive compatible and individually rational conditions. Perhaps not surprisingly, the revenue optimal dynamic auctions are computationally hard to find and existing literatures that aim to approximate the optimal auctions are all based on solving complex dynamic programs. It remains largely open on the structural interpretability of the optimal dynamic auctions.
In this paper, we show that any optimal dynamic auction is a virtual welfare maximizer subject to some monotone allocation constraints. In particular, the explicit definition of the virtual value function above arises naturally from the primal-dual analysis by relaxing the monotone constraints. We further develop an ironing technique that gets rid of the monotone allocation constraints. Quite different from Myerson’s ironing approach, our technique is more technically involved due to the interdependence of the virtual value functions across buyers. We nevertheless show that ironing can be done approximately and efficiently, which in turn leads to a Fully Polynomial Time Approximation Scheme of the optimal dynamic auction.

Abstract

Background
Canada has an established publicly funded health care system with a complex drug approval and funding process. After proof of efficacy (POE; key publication/presentation) and before becoming publicly accessible, each drug undergoes a Health Canada approval process, a health technology assessment (HTA), a pricing negotiation, and finally individual provincial funding agreements. We quantified potential life-years lost during this process.

Methods
We analyzed drugs for advanced lung, breast, and colorectal cancer that underwent the HTA process between 2011 and 2016. Life-years lost were calculated by multiplying documented improvement in progression-free and overall survival, number of eligible patients, and time from POE to first public funding. For conservative calculation, we assumed all eligible patients in Canada had access at the time of first public funding, whereas in reality provinces fund at different time points.

Results
We analyzed 21 drugs. Of these, 15 have been funded publicly. The time from POE to first public funding ranged from 14.0 to 99.2 months (median 26.6 months). Total overall life-years lost from POE to first public funding were 39,067 (lung 32,367; breast 6,691). Progression-free life-years lost from POE to first public funding were 48,037 (lung 9,139, breast 15,827, colorectal 23,071).

Conclusion
The number of potential life-years lost during the drug regulatory and funding process in Canada is substantial, largely driven by delays to funding of colorectal cancer drugs. Recognizing that interprovincial differences exist and that eligible patients may not all receive a given drug, if even a fraction does so, the impact of delays remains substantive. Collaborative national initiatives are required to address this major barrier to treatment access.
A COGNITIVE PERSPECTIVE ON THE ARABIC SPATIAL NOUN/ فَوْقَ /FAWQA/ APPLYING THE PRINCIPLE POLYSEMY MODEL
Authors: Mardiah Zaqiatul , Wastono Afdol Tharik , Muta’ali Abdul 
Published: September 2019

<p class="TeksAbstrak">The present paper provides a cognitive linguistics (CL) framework for analyzing the semantic structure of Arabic spatial noun <em>fawqa</em> based on <em>Principled Polysemy Model </em>(PPM) of Tyler and Evans (2003). PPM approach can broaden the narrow view of classical cognitive linguists regarding the semantic variation in the concept of physical-geometry of a preposition. As a polysemous lexeme,<em> fawqa</em> used by Arabian native to express a broad range of meanings, not only spatial relation but also non-spatial relation. The substantial sense of the lexeme is investigated using a large amount of corpus data (<em>corpus.kacst.edu.sa</em>) and applying the five steps of PPM approach. Through this approach, we ascertain that every single usage of <em>fawqa </em>expressing extended senses is always in its semantic network. Our study reveals that the usages of this lexeme in many situations and many cases show non-up down spatial relation, and non-physical relation, but they essentially refer to the primary sense.</p>
GLOBAL ERAS AND LANGUAGE DIVERSITY IN INDONESIA: TRANSDISCIPLINARY PROJECTS TOWARDS LANGUAGE MAINTENANCE AND REVITALIZATION
Authors: Collins James T. 
Published: September 2019

<p>Indonesia is immensely proud of its hundreds of regional languages. This amazing diversity occurs because of the social impact in the three global eras: ancient migration from Asian continent, trading intensification and colonial oppression five hundred years ago, and demographical and communication change in the 21st century. However, now we are witnessing the number decrease of the languages in Indonesia. The resistance and preservation of the inherited languages, which are local languages, in the Indonesian archipelago (Nusantara) language network that is indeed complex must be considered as important components in the Indonesia’s national identity.</p><p> Along with the accelerated loss of the inherited languages, we are also dealing with the ecological crisis happening in Indonesia. In the 19th century linguistics developed in connection with the progress of biology. Hence, in the 21st century, the handling and studies of languages that are endangered are reasonably related to the contemporary focus on the global ecology studies. Nettle (1999) asserted that the world regions with the high biological diversity are also the regions with the high language diversity. Any research on Nusantara’s flora and fauna should be correlated with the study of endangered languages and dialects.</p><p> In this paper, we review transdisciplinary planning which is capable of producing understanding and comprehension on the ecological system and regional language community as well as the perspective on the role of the knowledge in order for the academicians and members of the community to make more joint efforts to maintain the ecological system and the Nusantara language network.</p>

Published: September 2019

AbstractGround‐motion modeling requires accurate representation of the earthquake source, path, and site. Site amplification is often modeled by VS30, the time‐averaged shear‐wave velocity of the top 30 m of the Earth’s surface, though recent studies find that its ability to accurately predict site effects varies. Another measure of the site is κ0, the attenuation of high‐frequency energy near the site (Anderson and Hough, 1984). We develop a novel application of the Andrews (1986) method to simultaneously invert the spectra of 3357 earthquakes in Southern California into source and site components. These earthquakes have magnitudes 2.5–5.72 and were recorded on 16 stations for a total of 52,297 records. We constrain the inversion with an individual earthquake, demonstrating the most Brune‐like shape to preserve the site spectra. We then solve for κ0 site amplification at each station in three frequency bands: 1–6 Hz, 6–14 Hz, and 14–35 Hz. The resulting values of κ0 range from 0.017 s at ANZA station PFO to 0.059 s at ANZA station SND. We compare our results to values of site κ0 from other studies, as well as site residuals from ground‐motion prediction equations. We find good agreement between our site κ0 and previous studies in the region. We find that κ0 and high‐frequency site amplification (14–35 Hz band) correlates well with independent site residuals, making it a good first‐order approximation for the effects of site attenuation or amplification on ground motion.

Published: September 2019

ANTECEDENTES: Los gemelos siameses son casos excepcionales en la práctica médica (incidencia de 1 en 50,000 a 1 en 100,000 nacidos vivos). Los gemelos unidos pueden ser simétricos o asimétricos, cuando un gemelo está completo y sano (gemelo autósito) y el otro es incompleto (gemelo parásito) y depende del autósito para su crecimiento.CASO CLÍNICO: Gemelos siameses, de dos días de vida extrauterina, intervenidos quirúrgicamente para separar al no viable, por agenesia casi total (únicamente estaba constituido por la región cefálica y tronco dismórfico). El resto de las estructuras del gemelo sano, de género femenino, se observaron sin alteración. El procedimiento se llevó a cabo mediante una incisión lateral izquierda y la separación por planos desde la piel, el tejido celular subcutáneo y los trayectos musculares hasta identificar los órganos herniados del gemelo dominante al parásito; ningún órgano vital se encontraba compartido, solo se observó la herniación de una pequeña porción del hígado y de las asas intestinales del gemelo dominante al parásito, por lo que se reintrodujo el sistema digestivo del gemelo dominante y se efectuó la extirpación completa del gemelo parásito. Se cerró la pared con colocación de una malla plana para evitar una posible recidiva de la herniación. El trans y posoperatorio transcurrieron sin complicaciones y con evolución satisfactoria.CONCLUSIONES: La incidencia de gemelos siameses es excepcional. El diagnóstico prenatal se establece por ecografía; sin embargo, la resonancia magnética muestra mejor definición anatómica de las anomalías y permite la planificación obstétrica y los cuidados posnatales adecuados.

Published: September 2019

Purpose of the study: The purpose of this paper is to assess the knowledge sharing and job performance from psycho-social perspectives on Al Ain Municipality in UAE.
Methodology: Since this is a conceptual study, so this paper only focuses on the literature survey and logical explanation based on the facts discussed.
Results: The results of this study show that loss of knowledge can result in duplication of work, unreasonable searches for expertise and knowledge, and employees not learning from the experienced. Not all knowledge in the organisations is of critical value, and therefore need not be captured and retained, but the critical knowledge that is at risk of loss should be captured.
Implications: The awareness of knowledge loss through staff attrition may motivate companies to institutionalise specific processes to capture the tacit knowledge of their employees as much as possible. It is advisable for firms to have strategies in place on how to capture and retain their workforce’s knowledge.
Novelty: This research contributes significantly on the knowledge management from psycho-social perspectives and from the vantage point of United Arab Emirates. Upon the analysis of the data collected, the research may provide recommendations for the policy makers, academicians, practitioners as well as decision-makers and other stakeholders.

A partir do histórico da organização do III Encontro de História da Educação do Estado do Rio de Janeiro, ocorrido em 2013, da análise dos trabalhos aprovados e de sua distribuição por Eixos Temáticos, realizamos um balanço da produção. Interrogamos os enquadramentos das pesquisas e problematizamos o que a distribuição dos trabalhos revela e encobre sobre o campo. A análise comparativa da distribuição dos trabalhos pelos eixos das três edições do Congresso evidencia oscilações, permanências e rupturas na configuração do campo de pesquisa em História da Educação. A operação historiográfica que ensaiamos, ao visitar os quintais do EHED, lança questões sobre como o tema da história local e regional tem incidido na construção de uma história da educação carioca e fluminense.

Published: September 2019

Este estudo tem como objetivo apresentar os grandes embates e os sujeitos sociais envolvidos durante a implantação dos centros integrados de educação pública (CIEPs) enquanto Leonel Brizola e Darcy Ribeiro estavam à frente do governo do estado do Rio de Janeiro (1983-1987/1991-1994) e por isso, nosso recorte estará limitado a apenas ao período do primeiro governo de Leonel Brizola. Utilizamos documentos coletados no acervo da Fundação Darcy Ribeiro que tratam de assuntos referentes ao Programa Especial de Educação, no qual os CIEPs estavam inseridos. Além disso, buscamos estabelecer um diálogo com autores que já se propuseram estudar sobre os CIEPs. Podemos observar que os argumentos de defesa e as críticas à política dos CIEPs assumiram linhas de sustentação e meios de publicação para estabelecidos nessa arena de debates.
