The ABCs of Economic Crisis: What Working People Need to Know (review)
Year: 2011

This book is valuable for comparative studies of the labour market and organizing strategies in global cities. In this sense, the book could be useful not only for academics but also for activists. An interesting issue raised is the strategic importance of faith based organizing. The only sticking point I have with the authors is the characterization of a migrant division of labour which is supposedly new. There is an implication that there was no migrant citizen dynamic in the pre 1980s period and that what we have today is something categorically novel. It is implied that in earlier decades, immigrants and asylum seekers became British citizens, therefore the politics of being migrant or citizen was not significant. This is debatable. Citizenship does not only consist of a legal document. It involves inclusion of 'outsiders' into a (white) nation and is a highly contentious process. Despite having citizenship on paper, were earlier immigrants accepted as Britishers? Part of the racism they faced was that Blacks, which included Asians in those years, were never considered as part of the 'Union Jack. As against that, today's non white precarious workers are not only racialized socially but also legally by being denied British citizenship. EU workers who are part of the migrant working class hold a 'European' (white) identity and are preferred by employers over their nonwhite counterparts. Employer preference of white workers over non white workers continues. Old and new forms of exclusions could be analyzed in a more nuanced manner. No doubt, the class divisions in migrant and immigrant communities have become more significant, which have inevitably changed the forms of racism experienced by them and their identification as 'British, 'Black, 'Indian' or 'Bangladeshi. There are highly skilled, middle class immigrants who are eligible for citizenship rights unlike their unskilled working class counterparts. The issues of class divisions among migrant/immigrant communities and its impact on anti racism organizing could be further explored. Overall, I recommend this book highly for activists and researchers, and for undergraduate and graduate courses. Tania Das Gupta York University
The Role of Financial Literacy and Money Education on Wealth Decisions
Year: 2018

We investigate the impact of financial education on a wide range of wealth decisions using Dutch data from the DNB Household Survey. We consider two indexes representative of basic and advanced financial literacy acquired when adults, and money education received from the family during adolescence. Advanced financial literacy is a significant determinant of all the wealth outcomes under examination, while basic financial literacy affects only the propensity to plan for retirement and the likelihood of holding debt. Studying the individual components of financial literacy, the most relevant effects are associated with the understanding of numeracy and inflation, together with the correct knowledge of market mechanisms. Interestingly, money education received from the family during adolescence is as important as advanced financial literacy to foster individuals' wealth decisions. We also find evidence of a gender gap, with males' wealth decisions more affected by higher levels of financial education. Our results highlight the importance of improving financial knowledge not only through proper educational programs when adults, but also in the family environment during adolescence, where teens can learn positive attitudes towards money that are maintained throughout their life.
Growth of Sobolev norms in time dependent semiclassical anharmonic oscillators
Year: 2019

We consider the semiclassical Schrodinger equation on \mathbb R^d$ given by \mathrm{i} \hbar \partial_t \psi \left( \frac{\hbar^2}{2} \Delta W_l(x) \right)\psi V(t,x)\psi where $W_l$ is an anharmonic trapping of the form $W_l(x) \frac{1}{2l}\sum_{j=1}^d x_j^{2l} $l\geq 2$ is an integer and \hbar$ is a semiclassical small parameter. We construct a smooth potential $V(t,x) bounded in time with its derivatives, and an initial datum such that the Sobolev norms of the solution grow at a logarithmic speed for all times of order \log^\frac12}\hbar^ 1} The proof relies on two ingredients: first we construct an unbounded solution to a forced mechanical anharmonic oscillator, then we exploit semiclassical approximation with coherent states to obtain growth of Sobolev norms for the quantum system which are valid for semiclassical time scales.
Effect of Short Term Meditation on Brain Computer Interface Performance
Year: 2014

Brain Computer Interface (BCI) systems is a direct communication pathway between the brain and an external device. BCI systems enable patients with severe neuromuscular disorders to use their brain signal to communicate with others. BCI users need to maintain stable mental states to achieve a higher accuracy rate, while distraction and frustration will degrade the performance. Research had found that long term mindfulness meditation practice can help increase regulate the mental state, and thus enhance the efficacy of BCI performance. A previous study showed that a 12 week mindfulness meditation practice programme improved BCI performance. However, long term meditation course require extensive time and financial commitment. Thus the current study examines whether a short term 4 week mindfulness meditation practice programme will promote a similar improvement in BCI performance. Undergraduate students were recruited for the study. BCI performance test been carry out before and after the intervention period to compare the changes. Preliminary results showed that all meditation subjects had improved their accuracy in BCI performance test after the 4 week meditation practice.
Mitigasi, Adaptasi Dan Peningkatan Ketahanan Sumber Daya Alam Serta Lingkungan Terhadap Kondisi Ekstrem Atau Bencana (Slow/Rapid Onset) Di Kawasan Pesisir Dan Pulau Kecil Wilayah Perbatasan (Kepulauan Aru) Adaptasi Dan Penguatan Neraca Air Tawar
Year: 2012

Kepulauan Aru terdiri dari beberapa daratan yang dipisahkan oleh selat selat yang terbentuk awalnya dari retakan struktur akibat dari pembubungan bagian tepi paparan tepian kontinen Sahul. Gejala penurunan teramati dibagian timur dan utara kepulauan, diperlihatkan oleh morfobatimetri dan sebaran mangrove serta terumbu karang. Sebagai pulau datar dan rendah pesisir dan pantainya, kepulauan Aru menyandang kerentanan dari ancaman muka laut tinggi kejadian ekstrem yang datang perlahan maupun dengan cepat. Kerentanan terhadap bencana meningkat karena pemukiman tumbuh dan berkembang di sepanjang pantai atau selat yang memisahkan bagian pulau utama dan pulau kecil di sekelilingnya. Kondisi iklim tropis dengan putaran musim kering dan basah memberi curah hujan tahunan relatif tinggi cukup mendukung keseimbangan neraca air pulau landai dataran rendah bila tidak terjadi kelainan siklus hidrologi. Perairan luas di sekitar kepulauan memberi latar belakang cuaca yang kadangkala menguat penyimpangannya menghasilkan angin kuat yang berpengaruh pada ketinggian dan kekuatan gelombang yang mengakibatkan penggenangan. Ancaman muka laut tinggi dapat berasal dari perairan Banda berupa gelombang tsunami pembangkitan dari gempa tektonik yang sangat tinggi kemungkinan kejadiannya. Dengan latar belakang tersebut, pesisir kepulauan Aru selain menyandang ancaman kerusakan fisik akibat muka laut tinggi, dengan ancaman ikutannya adalah rusaknya neraca air tawar tanah dangkal di pesisir, selain oleh kejadian ekstrem almiah juga dampak dari tekanan atropogen. Peta kerentanan geobiofisik hasil analisis pada kepulauan dan hasil analisis geohidrologi pesisir memberi gambaran kerentanan neraca air tawar pesisir. Adaptasi, pemulihan dan penguatan neraca dan sanitasi dirancang dan diusulkan dibangun di beberapa pemukiman sesuai tingkat ancaman yang disandangnya. Pemulihan dan penguatan ekosistim alamiah pesisir dan perairan sebagai pelindung pantai tetap diutamakan sebagai bentuk mitigasi bahaya muka laut tinggi seiring sosialisasi pengamanan lingkungan dan kesiapan tanggap bencana.

A New Preprocessing Approach for Mining Association Rule from Large Database
Year: 2014

As we know now a day's internet plays vital role in serving the needs of the user's on web. We can search the information, we can order the items and can do many things online. Different options are available for this, but many times we don't have time to go through all alternatives and decide the best one. In such case a Web Page Recommendation System will be helpful to suggest the pages which are most relevant to your current search. The Server log files are generated as a result of an interaction between the client and the service provider on web. Server log file contains the massive hidden valuable information related to the visitors, if we mined this, it can be used for predicting the navigation behavior of the users. However the task of discovering frequent sequence patterns from the server log is challenging as it consist of huge data. Most of the time this data is incomplete and because of that it can't be processed further for generating accurate knowledge. Proposed system focuses on adopting an intelligent technique that can provide personalized web service for accessing related web pages more efficiently and effectively. Proposed system uses two intelligent algorithms for predicting the user behavior's namely FP Growth and Eclat. These algorithms save the time and space problem of existing system. Further from the frequent pages pattern Direct and Indirect Association Rules are generated and based on that Ranking is provided to pages which will help recommendation system to recommend similar search pages. This paper focuses on new approach for preprocess web log data.
Palmitoylation of pulmonary surfactant protein SP C is critical for its functional cooperation with SP B to sustain compression/expansion dynamics in cholesterol containing surfactant films.
Venue: Biophysical journal
Year: 2010

Recent data suggest that a functional cooperation between surfactant proteins SP B and SP C may be required to sustain a proper compression expansion dynamics in the presence of physiological proportions of cholesterol. SP C is a dually palmitoylated polypeptide of 4.2 kDa, but the role of acylation in SP C activity is not completely understood. In this work we have compared the behavior of native palmitoylated SP C and recombinant nonpalmitoylated versions of SP C produced in bacteria to get a detailed insight into the importance of the palmitic chains to optimize interfacial performance of cholesterol containing surfactant films. We found that palmitoylation of SP C is not essential for the protein to promote rapid interfacial adsorption of phospholipids to equilibrium surface tensions ~22 mN/m) in the presence or absence of cholesterol. However, palmitoylation of SP C is critical for cholesterol containing films to reach surface tensions =1 mN/m at the highest compression rates assessed in a captive bubble surfactometer, in the presence of SP B. Interestingly, the ability of SP C to facilitate reinsertion of phospholipids during expansion was not impaired to the same extent in the absence of palmitoylation, suggesting the existence of palmitoylation dependent and independent functions of the protein. We conclude that palmitoylation is key for the functional cooperation of SP C with SP B that enables cholesterol containing surfactant films to reach very low tensions under compression, which could be particularly important in the design of clinical surfactants destined to replacement therapies in pathologies such as acute respiratory distress syndrome.
Topical Application of Retinyl Palmitate Loaded Nanotechnology Based Drug Delivery Systems for the Treatment of Skin Aging
Venue: BioMed research international
Year: 2014

The objective of this study was to perform a structural characterization and evaluate the in vitro safety profile and in vitro antioxidant activity of liquid crystalline systems (LCS) with and without retinyl palmitate (RP) LCS containing polyether functional siloxane (PFS) as a surfactant, silicon glycol copolymer (SGC) as oil phase, and water in the ratios 30 25 45 and 40 50 10 with (OLSv RP loaded opaque liquid system and TLSv RP loaded transparent liquid system, respectively) and without (OLS and TLS, respectively) RP were studied. Samples were characterized using polarized light microscopy (PLM) and rheology analysis. In vitro safety profile was evaluated using red cell hemolysis and in vitro cytotoxicity assays. In vitro antioxidant activity was performed by the DPPH method. PLM analysis showed the presence of lamellar LCS just to TLS. Regardless of the presence of RP, the rheological studies showed the pseudoplastic behavior of the formulations. The results showed that the incorporation of RP in LCS improved the safety profile of the drug. In vitro antioxidant activity suggests that LCS presented a higher capacity to maintain the antioxidant activity of RP. PFS based systems may be a promising platform for RP topical application for the treatment of skin aging.
Grand Pwning Unit: Accelerating Microarchitectural Attacks with the GPU
Venue: 2018 IEEE Symposium on Security and Privacy (SP)
Year: 2018

Dark silicon is pushing processor vendors to add more specialized units such as accelerators to commodity processor chips. Unfortunately this is done without enough care to security. In this paper we look at the security implications of integrated Graphical Processor Units (GPUs) found in almost all mobile processors. We demonstrate that GPUs, already widely employed to accelerate a variety of benign applications such as image rendering, can also be used to "accelerate" microarchitectural attacks (i.e. making them more effective) on commodity platforms. In particular, we show that an attacker can build all the necessary primitives for performing effective GPU based microarchitectural attacks and that these primitives are all exposed to the web through standardized browser extensions, allowing side channel and Rowhammer attacks from JavaScript. These attacks bypass state of the art mitigations and advance existing CPU based attacks: we show the first end to end microarchitectural compromise of a browser running on a mobile phone in under two minutes by orchestrating our GPU primitives. While powerful, these GPU primitives are not easy to implement due to undocumented hardware features. We describe novel reverse engineering techniques for peeking into the previously unknown cache architecture and replacement policy of the Adreno 330, an integrated GPU found in many common mobile platforms. This information is necessary when building shader programs implementing our GPU primitives. We conclude by discussing mitigations against GPU enabled attackers.
An Empirical Research on Negative Transfer in College Non English Majors Chinese English Sentence Translation
Year: 2013

Nowadays, the transferred errors in non English majors' Chinese English(C E) sentence translation, which have been ignored by many teachers, are very remarkable. It has deeply affected the total translation process and the accuracy of the translation version. Moreover, it also has affected the scores in all kinds of English tests for non English majors. This paper is an empirical research which focuses on the negative transfer of college non English majors in their C E sentence translation. The research approach is the C E translation test paper. The software Excel 2007 and SPSS 16.0 have been used to analyze. With respect to the results, the transferred errors in C E sentence translation, have taken up 73% especially in the field of syntax. The essential causes are found and some suggestions are given to College English Teaching based on the findings.
Digitalization and Its Impacts on Political Science Education and Research: The Case of South Korea
Year: 2019

The digital revolution has made an immense impact on our society. And witnessing recent events in all parts of the world, it does not require a logical leap to conclude that the revolution also brought about profound changes in the modus operandi of the modern representative democracy. However, surprisingly little attention has been paid thus far to how the discipline of political science as a scientific community has collectively absorbed, digested, and reflected on the issues of the digital revolution and its implications. The aim of this paper is to examine and provide an account of how South Korean political science and political scientists have dealt with the changes and challenges posed by the digital revolution, with special attention to the aspects of teaching, learning and research. Based on our survey of political science programs at major universities, the website of the Korea Open Course Ware, research publication records, etc. we argue that the political science community in South Korea and their work, belying responsible for analyzing the challenges and implications and to provide useful guidance, have been regrettably slow to keep up with the speed at which the society and technology advanced, a stark contrast to the fact that the ICT and the digital revolution have already been fully recognized and utilized by the mass public and the political elites in the country. Indeed, the discipline remains far behind, in both education and research. A vicious cycle has already been formed between the problems of insufficient researchers and research assistants and the dearth of relevant classes offered as part of the discipline's regular Shin Goo Kang shingookang@ajou.ac.kr Chan Wook Park, Ph.D. chwpark@snu.ac.kr 1 Associate Professor of Department of Political Science, College of Social Sciences Ajou University 2 Professor of Political Science International Relations, College of Social Sciences Seoul National University 2 Shin Goo Kang Chan Wook Park curriculum. Further, excessive emphasis on statistics and empirical methodology on top of insufficient theoretical background have rendered nascent research effort unproductive. Breaking the chain of this vicious cycle, we believe, calls for a solid policy initiative and implementation. In order to do so, however, we must first come to recognize the many hindrances confronting the discipline's progress.
User Oriented Multi Task Federated Deep Learning for Mobile Edge Computing
Venue: ArXiv
Year: 2020

Federated Learning (FL) is a recent approach for collaboratively training Machine Learning models on mobile edge devices, without private user data leaving the devices. The popular FL algorithm, Federated Averaging (FedAvg) suffers from poor convergence speed given non iid user data. Furthermore, most existing work on FedAvg measures central model accuracy, but in many cases, such as user content recommendation, improving individual User model Accuracy (UA) is the real objective. To address these issues, we propose a Multi Task Federated Learning (MTFL) system, which converges faster than FedAvg by using distributed Adam optimization (FedAdam) and benefits UA by introducing personal, non federated 'patch' Batch Normalization (BN) layers into the model. Testing FedAdam on the MNIST and CIFAR10 datasets show that it converges faster (up to 5x) than FedAvg in non iid scenarios, and experiments using MTFL on the CIFAR10 dataset show that MTFL significantly improves average UA over FedAvg, by up to 54% We also analyse the affect that private BN patches have on the MTFL model during inference, and give evidence that MTFL strikes a better balance between regularization and convergence in FL. Finally, we test the MTFL system on a mobile edge computing testbed, showing that MTFL's convergence and UA benefits outweigh its overhead.
Neural networks involved in voluntary and involuntary vocal pitch regulation in experienced singers
Venue: Neuropsychologia
Year: 2010

In an fMRI experiment, we tested experienced singers with singing tasks to investigate neural correlates of voluntary and involuntary vocal pitch regulation. We shifted the pitch of auditory feedback 25 or 200 cents) and singers either: (1) ignored the shift and maintained their vocal pitch or (2) changed their vocal pitch to compensate for the shift. In our previous study, singers successfully ignored and compensated for 200 cent shifts; in the present experiment, we hypothesized that singers would be less able to ignore 25 cent shifts, due to a prepotent, corrective pitch shift response. We expected that voluntary vocal regulation during compensate tasks would recruit the anterior portion of the rostral cingulate zone (RCZa) and posterior superior temporal sulcus (pSTS) as our earlier study reported; however, we predicted that a different network may be engaged during involuntary responses to 25 cent shifts. Singers were less able to ignore 25 cent shifts than 200 cent shifts, suggesting that pitch shift responses to small shifts are under less voluntary control than responses to larger shifts. While we did not find neural activity specifically associated with involuntary pitch shift responses, compensate tasks recruited a functionally connected network consisting of RCZa, pSTS, and anterior insula. Analyses of stimulus modulated functional connectivity suggest that pSTS and intraparietal sulcus may monitor auditory feedback to extract pitch shift direction in 200 cent tasks, but not in 25 cent tasks, which suggests that larger vocal corrections are under cortical control. During the compensate tasks, the pSTS may interact with the RCZa and anterior insula before voluntary vocal pitch correction occurs.
Social competence, social support, and academic achievement in minority, low income, urban elementary school children.
Year: 2008

Despite living in disadvantaged urban communities experiencing social and economic hardships, many children emerge with positive outcomes. Social emotional competence and social support were hypothesized to have strong influences on academic trajectories during the critical period of academic skill acquisition. Participants were 282 third grade students from six elementary schools in a Northwestern urban community. Beyond the importance of prior levels of academic competence, considerable variance in end of year academic outcomes was predicted by initial levels of academic social emotional competence and improvements in social emotional competence and perceived teacher support over the course of the year. Noteworthy is that findings were strongest for African American students, but methodological caveats regarding research with underachieving minority youth were discussed. The findings suggest that school psychologists and others designing interventions to improve achievement of disadvantaged students should address social emotional competencies and classroom climate, especially teacher support of students.
