Constraint-based discriminative dimension selection for high-dimensional stream clustering
Authors: Waiyamai Kitsana , Kangkachit Thanapat
Published: November 2018

Clustering data streams is one of active research topic in data mining. However, runtime of the existing stream clustering algorithms increases and their performance drop in the face of large number of dimensions. Complexity of the stream clustering methods is increased when perform on data with large number of dimensions. In order to reduce the clustering complexity, one possible solution consists in determining the appropriate subset of cluster dimensions via dimension projection. SED-Stream is an efficient clustering algorithm that supports high dimension data streams. The aim of this paper is to increase performance of SED-Stream in terms of both clustering quality and execution-time. In order to improve the clustering process, background or domain expert knowledge are integrated as “constraints” in SEDC-Stream. The new algorithm, SEDC-Stream, supports the evolving characteristics of the dynamic constraints which are activation, fading, outdating and prioritization. SEDC-Stream algorithm is able to reduce cluster splitting time, and place new incoming points to their suitable clusters. Compared to SED-Stream on the three real-world streams datasets, SEDC-Stream is able to generate a better clustering performance in terms of both purity and f-measure.

Published: November 2018

O resultado das eleições para a presidência dos Estados Unidos e o referendo que definiu a saída da Grã-Bretanha da União Europeia mostrou ao mundo o poder das fake news. Temendo que impacto semelhante seja sentido nas eleições deste ano no Brasil, diversos parlamentares apresentaram projetos de lei que pretendiam, em sua maioria, criminalizar e punir os atos de criação e compartilhamento de notícias falsas. As propostas, contudo, colidem com o já definido na Constituição Federal e com o Marco Civil na Internet em termos de liberdade de expressão e de imprensa. Este trabalho analisou a legislação vigente e as propostas dos parlamentares, e também recorreu a artigos de juristas para entender se é possível combater notícias falsas sem atingir os direitos constitucionais.

Software Defined Network (SDN) adalah salah satu evolusi terbesar dalam dunia jaringan komputer. Dengan adanya SDN kemudahan dalam mengontrol jaringan lebih mudah dibandingkan dengan jaringan komputer biasa. Dimana dengan SDN konfigurasi jaringan lebih terpusat dikarenakan adanya pemisahan antara data plane dengan control plane. Data Plane berada pada sisi perangkat switch sedangkan control plane berada pada sisi server. Ada dua jenis switch Openflow yakni software based Switch Opeflow dan Hardware Based Switch Opeflow. Dalam penelitian ini jenis switch yang di pakai adalah Software Based Openflow Switch yang di pasang pada perangkkat HG553. Isu keamanan adalah isu yang masih terbuka luas untuk diteliti dalam Software Defined Network. Salah satunya adalah DDoS. DDoS adalah kegiatan untuk membanjiri jaringan dengan Data sehingga lalulintas jaringan menjadi penuh dan jaringan tidak dapat diakses oleh orang yang tidak berhak. Jenis DDoS UDP Flooding adalah jenis DDoS Conectionless. Dalam penelitian menunjukan DDoS UDP Flooding yang terjadi dalam jaringan SDN menyebabkan jaringan SDN sulit untuk di akses dikarenakan Switch Opeflow terlepas dari kontroller dan menyebabkan penggunaan reource tinggi pada Switch Openflow.

Urban is the destination and center of all community activities. According to Harahap,(2013) states that each population has a significant increase and population growth.Communities living in cities are highly demanded to have high productivity in order tocompete and meet their individual needs. But it cannot be denied that there are some urbancommunities who are not able to compete with the population. The profession of ahousewife in one example is a society that is not competitive and unproductive. Based onnational socio-economic survey data from the Central Bureau of Statistics (2004) statedthat most mothers in cities from 40 years who have children are 63.3% of households and29.6% of them are career women. This is because being a housewife in a city depends moreon the husband's income. Lately in Indonesia there has been considerable economicupheaval in various sectors that have enabled an increase in various needs in variousregions of Indonesia.

Pufendorfove ideje moralnog prirodnog prava i njihova suvremena rezonanca
Authors: Šmit Dragan
Published: November 2018

Prirodno pravo kao temelj države, objašnjeno na precizan i znanstveni način, osnova je moralno-političkog argumenta Samuela von Pufendorfa, što se smatra njegovim najvećim doprinosom političkom diskursu. Njegovo djelo je nastavak pokušaja da se integrira zakon prirode u pravni sustav, izgradi društvo zasnovano na principima poštovanja i samopoštovanja i znanstveno ospori Aristotelova tvrdnja da ne može biti društvene sigurnosti u samom moralu čovjeka. Kao rodonačelnik ideje moralnog prirodnog prava, Pufendorf je dao nesumnjiv doprinos razvoju pravne znanosti jedinstvenim metodološkim spojem etike, prava, povijesti, teologije i politike. Njegove ideje federalizma, dvojnog suvereniteta, države kao pravne osobe, preventivne penologije, primata svjetovne vlasti i moralnih koncepata pojedinca na kojima se dalje temelje i države i savezi država, nepravedno su zaboravljeni, a mnogi pokušaji da se oživi njegovo djelo ostali su na razini reduciranja ovog izvrsnog znanstvenika na jedan mali djelić njegova rada.

Perceived Challenges of Using Web-Based Library Services by Students in Prof. Festus Aghabgo Nwako Library, Nnamdi Azikiwe University, Awka, Nigeria
Authors: Esther Ekene Aghauche  , Udem Obiora Kingsley , Ogalanya Emeka Kingsley
Published: November 2018

Purpose: This study investigated the challenges confronting the use of web-based library services in Prof. Festus Aghagbo Nwako Library, NnamdiA zikiwe University, Awka.Methodology: The study adopted descriptive survey research design. The population comprised of 4,529 registered student users of the library and the sample size was 200 students accidentally selected while using the library. Questionnaire was used as the instrument for data collection and the data collected were analyzed using mean.Findings: The result revealed that challenges such as lack of awareness of available web-based services, lack of fund and high cost of Internet services among others were confronting the use of web based services in the library.Implications: lack of awareness of available web-based library services as major challenge to the use of the services shows that students were not aware of these services hence the need for academic libraries to market their web-based services.Value/Originality: The study’s educational value rest on the recommendations that the library should create awareness of available web-based services and the university authority should provide more funds to enable the library to fully upgrade its web-based services so that a true virtual experience could be derived from the use of these services.
Extent of Information and Communication Technology Skills Possessed by Librarians in University Libraries in Anambra State, Nigeria
Authors: Nkamnebe Emenike Chiemeka , Okeke Ifeka Ejike , Udem Obiora Kingsley , Nkamnebe Chibuzor Blessing
Published: November 2018

Persistent innovations and advances in Information and Communication Technology have substantially modified the way information is acquired, processed, stored, retrieved, and communicated. This has consequently changed the ways the library, which is visibly and significantly placed in the profession of information management operates, hence creating the need for library and information professionals to be sufficiently skilled in ICT operations which are now necessary for effective information services delivery. However, users are seemingly starved with services which the library professionals are expected to deliver through the use of ICTs. This implies that librarians are possibly not conversant with ICTs that they might be unable to respond to users’ needs promptly and render excellent library service to users as well. This is an ugly situation and may likely bring discredit to librarians and library profession in this 21st Century. This study therefore surveyed extent of Information and Communication Technology skills possessed by librarians in the universities in Anambra State, Nigeria. The research design adopted for this study is descriptive survey. The population consists of thirty-three (33) librarians in the five universities in Anambra State. Population was small hence, the whole subjects were studied. Two instruments - achievement test and questionnaire were used for data collection. Data obtained were analyzed using simple percentages, frequencies, and mean rating. Findings of the study include: Librarians in the universities in Anambra State are weakly skilled in ICTs hence their overall average percentage score in ICT skills was 58.3%. Their average percentage scores in dimensions of ICT are as follows: Basic Computing 83%, File Management 71%, Word Processing, 76%, E-mail operations 54%, Automated Cataloguing and Classification/use of OPAC 42%, use of Library Automation Software 56%, use of the Internet/WWW 61%, Information Search and Retrieval 62%, Presentation using Microsoft Power Point, 40%, Database Creation/Management 38%. Average percentage scores showed that librarians are highly-skilled in Basic Computing, Word Processing, and File Management and are moderately-skilled in Information Search and Retrieval, Internet and World Wide Web. They are weakly-skilled in Library Automation, E-mail operations, and are not skilled in Automated Cataloguing and Classification/use of OPAC, presentation using Microsoft Power Point, Database Creation/Management. Challenges militating against librarians’ ICT skills acquisition were identified and solutions were proffered.
Evidence for second-order singleton suppression based on probabilistic expectations
Authors: Won Bo Yeong , Kosoyan Mary , Geng Joy
Published: November 2018

Decades of research in attention have shown that salient distractors (e.g., a color singleton) tend to capture attention. However, in most studies, singleton distractors are just as likely to be present as absent. We therefore have little knowledge of how probabilistic expectations of the salient distractor's occurrence and features affect suppression. In three experiments, we explored this question by manipulating the frequency of a singleton distractor and the variability of its color within a search display. We found that increased expectations regarding the occurrence of the singleton distractor eliminated the singleton RT cost and reduced the number of first saccades to the singleton. In contrast, expectations regarding variability in the singleton color did not affect singleton capture. This was surprising and suggests the ability to suppress second order salience over and above that of first order features. We next inserted the probe display that included a to-be-reported letter inside each shape between search trials to measure if attention went to multiple objects. The letter in the singleton location was reported less often in the high frequency condition, suggesting proactive suppression of expected singleton. Additionally, we found that trial-to-trial repetitions of a singleton (irrespective of its color and location) facilitated performance (i.e., singleton repetition priming), but repetitions of its specific color or location did not. Together our findings demonstrate that attentional capture by a color singleton distractor is attenuated by probabilistic expectations of its occurrence, but not of its color and location.

Published: November 2018

The study investigated the information literacy competencies possessed by Library and Information Science (LIS) postgraduate students in Federal Universities in South East Zone Nigeria with a focus on the Knowledge and skill level. Descriptive survey design was adopted for the study. Seventy two students which included all 2011/2012 PhD and Masters degree students from the Departments of LIS in Nnamdi Azikiwe University, Awka and University of Nigeria, Nsukka. Data was collected using Achievement Test and Questionnaire. Percentages, frequencies and mean rating were used to answer research questions. T-test was used to test hypotheses. The major findings of the study include: LIS postgraduate students in Federal Universities in South East Zone Nigeria possessed information literacy knowledge since the measure based on understanding the need for information, how to locate, evaluate and use information have average percentage scores of 95%, 87%, 82% and 88% respectively. However, the information literacy knowledge possessed by LIS Postgraduate students in Nnamdi Azikiwe University, Awka (NAU) differed significantly from those possessed by LIS Postgraduate students in University of Nigeria, Nsukka (UNN); LIS postgraduate students possessed moderate level of information literacy skills as their level of information literacy skills as measured based on ability to locate and access, evaluate and use information has general mean rating of 3.34. However, the skills differed significantly between LIS Postgraduate students in NAU and UNN. Based on the findings, it was recommended that more practical aspect of information literacy should be employed through students industrial training and internship,and LIS curriculum should be enhanced especially with reference to skill acquisition.
Review, replication, and re-analysis of a recent study on the impact of abortion law on maternal mortality in Mexico – Maintaining rigor and research integrity
Authors: Koch Elard , Chireau Monique , Stanford Joseph , Haddad Sebastian , Pliego Fernando , Bravo Miguel , Thorp John
Published: November 2018

This report provides a review, replication, and re-analysis of an study by Darney et al (Contraception. 2017;95(1):105-111) on the association between maternal mortality ratio (MMR, number of maternal deaths per 100,000 live births) and abortion legislation in Mexico City compared with 31 other states. In their study, Darney et al disputed evidence from our study (Koch et al, BMJ Open 2015;5(2):e006013), which found a null association between abortion laws and MMR, and reported their own conclusion of a negative association between abortion availability and MMR. After replicating their dataset and statistical analysis, we found that the beta coefficient (effect size) for abortion legislation was apparently misinterpreted by Darney et al to support the conclusion that legislation allowing abortion on request in Mexico City was associated with a 22.49-unit decrease in MMR. In fact, their analysis showed the opposite result: after multivariable adjustments, Mexico City was associated with a 22.49-unit increase in MMR compared with the 31 states with restricted access to abortion. Moreover, Darney et al did not report the initial time-adjusted effect size, where the 95% CI supports the hypothesis of null association (beta = 4.17; 95%CI -7.19 to 15.54; p=0.470). In our re-analysis of their data, estimates were highly unstable in multiple regression models, and the initial effect size (4.17) for the association between abortion legislation and the MMR was inflated up to 5-fold (22.49) as a result of a ‘tipping effect’ on coefficients and multicollinearity among covariates. In conclusion, our reanalysis of Darney et al’s study provides evidence of serious methodological flaws, faulty statistical analysis and misinterpretation of regression coefficients, ultimately resulting in an invalid conclusion.
Agency Correlates of Police Militarization: The Case of MRAPs
Authors: Burkhardt Brett C , Baker Keith
Published: November 2018

In 2014, protests in Ferguson, Missouri (MO), and the subsequent law enforcement response, shined a light on police militarization—the adoption of military styles, equipment, and tactics within law enforcement. Since 1990, the U.S. Department of Defense has transferred excess military equipment to domestic law enforcement agencies via the federal 1033 program. This article examines transfers of mine-resistant ambush-protected vehicles or MRAPs. Designed to withstand explosive blasts during U.S. military occupations in Iraq and Afghanistan, surplus MRAPs have been shipped to more than 800 domestic law enforcement agencies. This article uses national data on law enforcement agencies and on 1033 program transfers to analyze the pattern of MRAP distribution. The results show that MRAPs are disproportionately acquired by agencies that have warrior tendencies and rely on asset forfeiture to generate revenue. This pattern of militarization is consistent with a model of governance that views citizens as both opportunities and threats.

Polyblend dari polisakarida dan polivinil alkohol telah diteliti untuk kanji benang lusi pada proses tekstilpertenunan. Polyblend dibuat dengan cara pencampuran dalam bentuk gel dari polisakarida dan polivinil alkohol denganperbandingan 9:1. Beberapa polisakarida tumbuh-tumbuhan ditentukan titik gel dan viskositas untuk memilihkompatibilitasnya dengan polivinil alkohol. Penganjian dilakukan pada tiga macam benang lusi yaitu benang kapas 100%,benang poliester-kapas 65/35%, dan benang filamen poliester 100%. Terhadap hasil penganjian dilakukan pengujian sifatelektrostatik menggunakan rotary electrostatic meter, kekuatan tarik dan mulur menggunakan tensile tester, daya tahangesekan, dan uji penghilangan kanji (desizing). Sebagai pembanding digunakan kanji sintetik dari jenis akrilik. Hasilpengujian menunjukkan bahwa polyblend dari polisakarida jagung dan polivinil alkohol dapat menurunkan sifatelektrostatik secara signifikan terutama pada benang filamen poliester yaitu dari 1000 volt menjadi 8 volt. Polyblenddapat meningkatkan kekuatannya pada benang staple kapas sebesar 64,286%, dan pada benang staple poliester-kapassebesar 26,07%, sedangkan pada benang filamen poliester naik 2,14%. Polyblend dapat mempertahankan kekuatannyagesekan benang kapas sampai 3000 kali yang berarti menyamai ketahanan gesekan kanji akrilik. Hasil uji penghilangankanji menunjukkan bahwa kanji polyblend dapat dihilangkan secara sempurna.

Dalam penelitian ini dilakukan evaluasi terhadap proses dekolorisasi fotokatalitik air limbah tekstil artifisialmengandung zat warna azo Acid Red 4 (AR4) dengan menggunakan katalis mikropartikel TiO2 dan ZnO. Tujuanpenelitian ini adalah untuk menentukan proses fotokatalitik optimum dengan menganalisis pengaruh variabel antaralain: pH, konsentrasi awal zat warna, dosis katalis, kombinasi katalis, dan temperatur awal air limbah. Evaluasi terhadapefisiensi dan laju dekolorisasi dilakukan melalui pengukuran absorbansi menggunakan spektrofotometer.Proses dekolorisasi fotokatalitik AR4 ditemukan berlangsung efektif pada kondisi optimum: pH 11, konsentrasiawal zat warna 10 mg/L dan dosis katalis 0,5 g/L baik untuk mikropartikel TiO2 maupun ZnO. Setelah waktu irradiasiselama 2 jam, proses dengan mikropartikel ZnO mampu mencapai efisiensi dekolorisasi lebih baik (89,9%)dibanding mikropartikel TiO2 (86,9%). Berdasarkan kinetika reaksi pseudo orde pertama, dekolorisasi fotokatalitikmenggunakan mikropartikel ZnO memperlihatkan laju lebih cepat (k’= 0,022 menit-1) dibandingkan denganmikropartikel TiO2 (k’= 0,018 menit-1). Kombinasi kedua jenis katalis menyebabkan laju dekolorisasi menjadi lebihlambat (k’= 0,015 menit-1) dibandingkan penggunaan katalis secara individual. Temperatur awal air limbah yanglebih tinggi ditemukan menyebabkan penurunan efisiensi dekolorisasi fotokatalitik.
