Fully Online Matching
Authors: Huang Zhiyi , Kang Ning , Tang Zhihao Gavin , Wu Xiaowei , Zhang Yuhao , Zhu Xue 
Published: May 2020

We introduce a fully online model of maximum cardinality matching in which all vertices arrive online. On the arrival of a vertex, its incident edges to previously arrived vertices are revealed. Each vertex has a deadline that is after all its neighbors’ arrivals. If a vertex remains unmatched until its deadline, then the algorithm must irrevocably either match it to an unmatched neighbor or leave it unmatched. The model generalizes the existing one-sided online model and is motivated by applications including ride-sharing platforms, real-estate agency, and so on.
We show that the Ranking algorithm by Karp et al. (STOC 1990) is 0.5211-competitive in our fully online model for general graphs. Our analysis brings a novel charging mechanic into the randomized primal dual technique by Devanur et al. (SODA 2013), allowing a vertex other than the two endpoints of a matched edge to share the gain. To our knowledge, this is the first analysis of Ranking that beats 0.5 on general graphs in an online matching problem, a first step toward solving the open problem by Karp et al. (STOC 1990) about the optimality of Ranking on general graphs. If the graph is bipartite, then we show a tight competitive ratio ≈0.5671 of Ranking. Finally, we prove that the fully online model is strictly harder than the previous model as no online algorithm can be 0.6317 < 1- 1/e-competitive in our model, even for bipartite graphs.
Metaphilosophical Musings

It has been some time now since we have had our Philosopher's Corner feature in place at The DATA BASE for Advances in Information Systems, and we have seen some truly magnificent work appear in these pages in that time. I am gilding the lily in saying so, to be sure, but as an Editor-in-Chief, I have a certain pride of ownership in regard to it. I don't want to claim that The Philosopher's Corner was all my idea; we are a team here in the Editorial office, and we do things as a team and by consensus.
Even so, I have a great deal of enthusiasm for the feature and take it upon myself to shamelessly promote it at every turn and in every quarter. Just as I am now.
10 anos de um CAPSi
Authors: Leitão Iagor Brum , Avellar Luziane Zacché 
Published: May 2020

Objetivou-se identificar as percepções de profissionais trabalhadores de um CAPSi acerca do trabalho em saúde mental da criança e do adolescente e descrever os impasses e desafios vividos pelo serviço em seu décimo ano de funcionamento. Os dados foram analisados por meio da Classificação Hierárquica Descendente (CHD), possibilitada pelo software IRaMuTeQ. A CHD formou cinco classes: 1- “A clínica no CAPSi”, classe que compreende as interrogações dos profissionais acerca da dimensão clínica do CAPSi, especialmente no que se refere às condutas a serem adotadas para o cuidado de usuários com autismo; 2- “Articulação com a Rede”, onde situam-se desafios relacionados à efetivação da política intersetorial; 3- “Imaginário do serviço”, que ilustra o entendimento da população e demais serviços da rede acerca do CAPSi, frequentemente visto como um serviço clínico-ambulatorial centrado na especialidade psiquiátrica. 4- “Perfil dos usuários globais”, que remonta a lógica histórica de ações dedicadas à crianças e adolescentes considerados “desviantes”, condição que contribui para a prevalência de usuários provenientes de famílias com baixa renda e em vulnerabilidade social no CAPSi; 5- “O Cuidado de Usuários AD”, que denota a dificuldade do CAPSi constituir-se como um lugar possível para cuidado de usuários com necessidades decorrentes do uso de álcool e outras drogas
Os impasses do ensino superior privado brasileiro
Authors: Sena Isael 
Published: May 2020

Em nome da luta contra as desigualdades sociais e por considerar a exclusão massiva de jovens do acesso ao ensino superior, o governo brasileiro do ex-presidente Fernando Henrique Cardoso (1995-2003) implementou um conjunto de políticas públicas que possibilitaram a expansão dos sistemas de ensino primário e secundário, a qual repercutiu também no âmbito universitário. Na sequência, os governos de esquerda, inicialmente, o do ex-presidente Luíz Inácio Lula da Silva (2003-2011) e, em continuidade, o de Dilma Vana Roussef (2011-2016), contribuíram com esse mesmo processo ao ampliar o número de vagas nas instituições federais e, sobretudo, nas privadas. Com o fortalecimento da “privatização do ensino universitário”, as instituições merecedoras de subsídios financeiros indiretos do estado nacional, nos últimos anos, adquiriram, explicitamente, um caráter quase tão somente mercantil e lucrativo. A partir de tais considerações, interrogamos, na tese presente, por que os professores permaneceram trabalhando influenciados por esse modelo. Realizamos entrevistas com docentes de uma instituição privada a fim de possibilitar a estes profissionais um relato de suas experiências com a faculdade, os alunos e a transmissão. O estudo nos conduziu à compreensão de que a mercantilização da formação universitária, “à maneira brasileira”, produziu uma torção perversa ou cínica do laço subjetivo entre professor e aluno, pois impossibilitou o genuíno desdobramento desse vínculo e induziu, possivelmente, um quadro de apatia dos alunos e de melancolia formativa generalizada do professor. Contrariamente ao propalado, a formação universitária veio acompanhada de uma pauperização da qualidade da transmissão e da experiência necessárias à formação acadêmico-profissional. Ademais, os diplomas, atualmente, são desvalorizados no mercado de trabalho. Assim, a pretendida luta contra as desigualdades sociais resultou, com exagero, naquilo que ela visava combater. O professor, embora submetido ao caráter alienante e repressivo da instituição, associado à mercantilização do ensino, transmitiu a mesma demanda inconsciente de fazer gozar o Outro do mercado capitalista.
O que resta da adolescência
Authors: Rosa Miriam Debieux , Carmo-Huerta Viviani 
Published: May 2020

Os processos dos adolescentes diante dos dilemas humanos relativos à sexualidade, morte, pertença e transformação social contam a sua própria história, mas dizem também sobre o modo como cada sociedade concebe as modalidades de inscrição do sujeito no laço social, assim como da sua disponibilidade às transformações sociais. Neste artigo vamos demonstrar os impasses nos destinos da adolescência quando o outro social, em vez de interpelar, acompanhar e apostar no adolescente transforma suas fronteiras em opacidades intransponíveis, ao modo de um front de guerra, impondo impedimentos à sua pertença ao laço social. Vamos cotejar falas dos adolescentes da peça de teatro de Frank Wedekind, de 1891, O Despertar da Primavera, com falas de adolescentes das margens das grandes cidades brasileiras. Vamos demonstrar a articulação da sexualidade à cena social e política, assim como situar o estatuto do ato diante dos impasses do adolescente frente ao lugar que lhe é ofertado no discurso social. Pode-se escutar o que resta da adolescência: a construção de uma narrativa ficcional que permita construir e nortear a sua invenção de um lugar para existir.
Ocupa Escola
Authors: Coutinho Luciana Gageiro 
Published: May 2020

O artigo parte do pressuposto de que pensar a adolescência é também refletir sobre os impasses no laço social, incluindo-se aí o laço educativo e os discursos que o constituem. Sustenta que, no contexto escolar brasileiro, os laços dos adolescentes com a família e com a escola são muitas vezes marcados pela condição de vulnerabilidade social e por discursos educativos atravessados por especialismos e por exigências produtivistas. Esses sujeitos adolescentes são assim silenciados e tal condição de desamparo discursivo incide sobre o trabalho da adolescência dificultando a passagem do discurso infantil referido à família para os discursos sociais referidos ao Outro social. Defende que o sofrimento psíquico desses adolescentes é sociopolítico, ou seja, diz respeito aos impasses provenientes dos lugares que ocupam no laço social e nos discursos dominantes, de modo que o seu tratamento deve se dar também na dimensão do coletivo. Aborda alguns extratos de uma pesquisa sobre as ocupações das escolas ocorridas entre 2015 e 2017 em todo o Brasil para pensar sobre o trabalho da adolescência e um tratamento possível aos impasses no laço social que se apresentam na escola em nosso contexto contemporâneo.
Histone Deacetylase Inhibitors: A Novel Strategy for Neuroprotection and Cardioprotection Following Ischemia/Reperfusion Injury
Authors: Pickell Zachary , Williams Aaron M. , Alam Hasan B. , Hsu Cindy H. 
Published: May 2020

Abstract

Ischemia/reperfusion injury is a complex molecular cascade that causes deleterious cellular damage and organ dysfunction. Stroke, sudden cardiac arrest, and acute myocardial infarction are the most common causes of ischemia/reperfusion injury without effective pharmacologic therapies. Existing preclinical evidence suggests that histone deacetylase inhibitors may be an efficacious, affordable, and clinically feasible therapy that can improve neurologic and cardiac outcomes following ischemia/reperfusion injury. In this review, we discuss the pathophysiology and epigenetic modulations of ischemia/reperfusion injury and focus on the neuroprotective and cardioprotective effects of
histone deacetylase inhibitors
. We also summarize the protective effects of
histone deacetylase inhibitors
for other vital organs and highlight the key research priorities for their successful translation to the bedside.
Out of Plato’s Cave
Authors: Ostovich Steve 
Published: May 2020

Abstract
The title is lifted from an essay by J. T. Fraser in his book Time and Time Again (2007). It conveys Fraser’s conviction, a conviction shared here, that understanding time and reality requires us to redirect our thinking process. Plato describes a path out of the dark cave of confusion into the realm of truth and light, that is, from time towards the timeless. But we should “reverse course” along this path and move from the timeless into the complexity of time. Time is not one thing foundational to reality; reality rather is a series of temporal levels developed through evolution and related in a nested hierarchy driven by conflict and towards increasing complexity. This theory makes possible critical and fruitful reflection on issues like entropy, indeterminacy, and mind/body dualism. It entails embracing our position as knowers in time and the complexity of truth as temporal rather than timeless.
The Multisensory Experience of Handling and Reading Books
Authors: Spence Charles 
Published: May 2020

Abstract
The failure of e-books to take over from the traditional print format, as was so confidently predicted would happen only a few years ago, highlights how there is more to reading than merely the content of what we see. In fact, like any other object, the experience of interacting with a book, especially an old or historic volume, offers the reader the potential for a multisensory encounter. One that involves not only what the book looks and feels like, both the weight of the volume and the feel of the pages, but also the distinctive smell. In fact, one might also want to consider the particular sound made by the pages as they are turned over. However, it is the smell of older, and seemingly more olfactorily-redolent, works that appears to be especially effective at triggering nostalgic associations amongst readers. It is therefore only by understanding the multisensory nature of handling books, as stressed by this review, that one can really hope to fully appreciate the enduring appeal of the traditional format in the modern digital era. Several recent exhibitions that have attempted to engage their visitors by means of exploring the multisensory appeal of historic books or manuscripts in their collections are briefly discussed. While the multisensory mental imagery that is typically evoked by reading is unlikely to differ much between the print and e-book formats, there is nevertheless still some evidence to suggest that physical books can occasionally convey information more effectively than their digital counterparts.
On two species of the alpheid shrimp genus Salmoneus Holthuis, 1955 from Kuwait, one of them new to science (Malacostraca: Decapoda: Caridea)
Authors: ANKER ARTHUR , AL-KANDARI MANAL , DE GRAVE SAMMY 
Published: May 2020

The alpheid genus Salmoneus Holthuis, 1955 is reported from Kuwait for the first time, with two species. One species, Salmoneus ikaros sp. nov., is described based on a single specimen from Failaka Island, extracted from the burrow of the callianassid ghost-shrimp Balsscallichirus masoomi (Tirmizi, 1970), together with the host. The new species is characterised by its peculiar eyes, which together with other characters separate it from all previously described species of Salmoneus. The second species, Salmoneus gracilipes Miya, 1972, is reported from Kuwait based on three specimens from two different localities and different habitats. Two specimens were found under coral rocks at a depth of about 7 m off Kubbar Island, whereas the third specimen was extracted from the burrow of the echiuran worm, Listriolobus cf. brevirostris Chen & Yeh, 1958, at the type locality of S. ikaros sp. nov. at Failaka Island. Material identified as S. gracilipes from across its wide distribution range appears to be morphologically heterogeneous, possibly containing more than one species, and thus will need further studies.
A Hazard Multiple: Overlapping Tornado and Flash Flood Warnings in a National Weather Service Forecast Office in the Southeastern United States
Authors: Henderson Jen , Nielsen Erik R. , Herman Gregory R. , Schumacher Russ S. 
Published: May 2020

AbstractThe U.S. weather warning system is designed to help operational forecasters identify hazards and issue alerts to assist people in taking life-saving actions. Assessing risks for separate hazards, such as flash flooding, can be challenging for individuals, depending on their contexts, resources, and abilities. When two or more hazards co-occur in time and space, such as tornadoes and flash floods, which we call TORFFs, risk assessment and available actions people can take to stay safe become increasingly complex and potentially dangerous. TORFF advice can suggest contradictory action—that people get low for a tornado and seek higher ground for a flash flood. The origin of risk information about such threats is the National Weather Service (NWS) Weather Forecast Office. This article contributes to an understanding of the warning and forecast system though a naturalistic study of the NWS during a TORFF event in the southeastern United States. Drawing on literature for the Social Amplification of Risk Framework, this article argues that during TORFFs, elements of the NWS warning operations can unintentionally amplify or attenuate one threat over the other. Our results reveal three ways this amplification or attenuation might occur: 1) underlying assumptions that forecasters understandably make about the danger of different threats; 2) threat terminology and coordination with national offices that shape the communication of risks during a multihazard event; and 3) organizational arrangements of space and forecaster expertise during operations. We conclude with suggestions for rethinking sites of amplification and attenuation and additional areas of future study.
Evaluation of Recurrent Maxillary Sinusitis due to Middle Meatal Antrostomy Site Stenosis
Authors: Kim Hyo Jun , Choi Ji Ho , Lee Jae Yong 
Published: May 2020

Objective: This study was performed to evaluate the incidence, timing, and factors contributing to recurrent maxillary sinusitis due to middle meatal antrostomy (MMA) site stenosis after endoscopic sinus surgery (ESS). Methods: The medical records and endoscopic photographs of 288 patients with chronic rhinosinusitis who underwent ESS were evaluated. Patients visited the clinic with similar schedule after ESS; recurrent maxillary sinusitis due to MMA site stenosis was investigated, including in terms of the incidence and timing. The preoperative computed tomography (CT) scans, intraoperative findings, and possible factors contributing to MMA site stenosis were examined. Results: Recurrent maxillary sinusitis due to MMA site stenosis occurred in 10 patients. Most had unilateral sinusitis and stenosis was observed within 6 months postoperatively. All patients had severe inflammation, pus retention, and thick mucosal hypertrophy in the maxillary sinus on preoperative CT; intraoperative findings confirmed these conditions. In most patients, extensive trimming of the hypertrophied mucosa was performed intraoperatively through canine fossa trephination. Conclusions: MMA site stenosis is a rare condition after ESS. We hypothesized that rapid shrinkage and fibrosis of the sinus mucosa after extensive trimming thereof may be the main causes of stenosis. Residual mucosal inflammation, granulation formation, and persistent sinus crust and debris may also be contributing factors. Therefore, conservative trimming, meticulous dressing, and removal of sinus crust and granulation tissue near the MMA site should be performed in patients with MMA site stenosis.
Challenging the status quo: A comparison of ion exchange chromatography with liquid chromatography–mass spectrometry and liquid chromatography–tandem mass spectrometry methods for the measurement of amino acids in human plasma

Background Plasma amino acid analysis is key to the diagnosis and monitoring of inherited disorders of amino acid synthesis, catabolism and transport. Ion exchange chromatography (IEC) is widely accepted as the gold standard method of analysis, but with the introduction of liquid chromatography tandem mass spectrometry (LC-MS/MS) and liquid chromatography mass spectrometry (LC-MS) methods, this should now be questioned. Methods The analytical performance of three commercially available reagent kits, Waters AccQ Tag™ ULTRA LC-MS, SpOtOn Amino Acids LC-MS/MS and Chromsystems MassChrom® Amino Acid Analysis LC-MS/MS, were evaluated and compared with Biochrom Physiological Amino Acids ion exchange chromatography. Correlation with IEC was assessed by Passing-Bablok regression, concordance correlation coefficients (CCC) and Bland-Altman analysis for 21 common amino acids. Calculation of the total error from imprecision and bias was also used to benchmark performance. Results The MassChrom® and SpOtOn kits demonstrated acceptable inter-batch imprecision (CV < 10%) and accuracy (mean bias < 10%), whereas the AccQ Tag™ ULTRA kit did not. Good correlation (CCC > 0.95) with Biochrom IEC was demonstrated for 10/21 analytes in both the MassChrom® and SpOtOn kits and 6/21 in the AccQ Tag™ ULTRA kit. Conclusions The LC-MS assay demonstrated variable analytical performance and correlated poorly with ion exchange chromatography. Both LC-MS/MS assays demonstrated comparable analytical performance and reasonable correlation with ion exchange chromatography. They also confer practical advantages which cannot be realized by ion exchange chromatography, superior specificity and significantly faster analysis time, suggesting that ion exchange chromatography should no longer be described as the gold standard method for plasma amino acid analysis.

Published: May 2020

Objective: Antipsychotics are widely used for treating psychosis, but it is unclear whether they can also prevent psychosis. This study attempted a longitudinal evaluation of antipsychotics under real-world conditions in China to evaluate their effect on the rate of conversion to psychosis in individuals with a clinical high risk (CHR) of psychosis. Method: A total of 517 CHR individuals were recruited between 2011 and 2016 and followed up for 3 years. Among these, 450 (87.0%) individuals completed follow-up, 108 (24.0%) showed conversion to psychosis and 309 (68.7%) received antipsychotics. The main outcome was conversion to psychosis. The sample was further stratified according to the severity of positive symptoms. Results: Patients who did not receive antipsychotics showed a lower conversion rate than those who did (17.7% vs 26.9%; odds ratio [OR] = 0.660, 95% confidence interval [CI] = [0.442, 0.985], p = 0.035). In mild CHR cases, antipsychotic treatment was more likely to be associated with conversion to psychosis, compared with the no-antipsychotics group, with no such difference observed in severe CHR cases. Among those who received antipsychotics, monotherapy or low-dose treatment was associated with lower conversion rates. Our results did not favor any specific type of antipsychotics and suggested that a very small subgroup of CHR individuals with severe positive and general symptoms but mild negative symptoms may benefit from antipsychotic treatment. Conclusions: Administration of antipsychotics to CHR patients is potentially harmful with no preventive benefits. We do not recommend antipsychotic treatment for CHR individuals, which is practiced widely in China, and strongly advise caution if these drugs are used.
Brief cognitive screening instruments for electroconvulsive therapy: Which one should I use?
Authors: Martin Donel M , McClintock Shawn M , Loo Colleen K 
Published: May 2020

Objectives: To review brief cognitive screening instruments for routine clinical monitoring in electroconvulsive therapy. Methods: Brief cognitive screening instruments specifically developed for electroconvulsive therapy and commonly used brief generalised cognitive screening instruments were reviewed with relative advantages and disadvantages highlighted. Results: Several brief cognitive screening tests designed for use in electroconvulsive therapy have been found sensitive for monitoring electroconvulsive therapy–related cognitive side effects. The choice of a brief generalised cognitive screening instrument for use in an electroconvulsive therapy clinical context comes with several pertinent considerations. Conclusion: Electroconvulsive therapy is a highly effective treatment for pharmacoresistant and severe neuropsychiatric illness although cognitive side effects can be a barrier for treatment. Routine monitoring using brief cognitive screening instruments has advantages in busy clinical settings and can assist with optimising patient outcomes. More detailed neuropsychological assessment is recommended if the results from brief cognitive screening raise concerns.
