A Technology Adoption Model for Mobile-Enabled Government Services

The article centers its argument on a lack of a comprehensive model to explain individuals' adoption of m-government services. Features peculiar to m-government due to mobility—mobile technology effect, choice over alternative channels, and service cost burden to citizens—are among the determining factors for service quality, and adoption is not captured in prior models. Consequently, this article proposes a model that extends UTAUT2 and incorporates aspects from other two knowledge domains, technology domestication, and technology use and gratification domain. The proposed model is evaluated for its validity and reliability through data collected using a questionnaire from 396 randomly sampled residents of Dar es Salaam. The study contributes both theoretically and empirically to knowledge regarding technology adoption by incorporating new variables and extending variable definition for a richer and versatile analysis.

Extreme flow variability analysis at the Bianouan hydrometric station on the Bia River watershed in Côte d'Ivoire

Extreme hydrological phenomena recurrence in West Africa in recent decades is a problem in the anthropized watershed management. Link analysis between extreme hydrological phenomena and climate variability is necessary to guard against their consequences. However, qualitative data accessing difficulties and explanatory variable definition of extremes hydrological phenomena limit extreme flows rate studies. This study proposes the analysis the variability of the floods and the low flows at the Bianouan hydrometric station. Thus, five (5) floods characteristics variables (QCX5, QXJA, F90p, F95p and F99p) and three (3) for, the low flows (VCN10, QJNA and F10p) were extracted daily flows from the Bianouan hydrometric station from 1 January 1962 to 31 December 2005. The variability of these extremes has been studied by the trend analysis (linear regression) and of the stationarity (Pettitt and Hubert tests). The results show that for flood variables the negative trend is very significant and ruptures are observed in 1980. For low flow variables the negative trend is significant and the ruptures are observed in 1981. From this study, we can deduce that the ruptures observed in the rains and flows average in the end 1960s and early 1970s have affected later the extreme flows around the 1980s.

Vagusnervstimulation bei affektiven Störungen

ZusammenfassungVagusnervstimulation (VNS) ist ein minimalinvasives Neurostimulationsverfahren und wurde 1994 in Europa für die Behandlung von Kindern und Erwachsenen mit medikamentenresistenten Epilepsien zugelassen. Die Beobachtung, dass sich Depressionen, die häufigste Komorbidität der Epilepsie, signifikant unter VNS verbesserten, initiierte Studien der VNS bei Patienten mit therapieresistenten Depressionen (TRD), die 2001 zu der europäischen Zulassung der VNS für TRD führten. Heutzutage ist in Deutschland der Einsatz der VNS für TRD-Patienten auf wenige hochspezialisierte (oft universitäre) Zentren limitiert und das Verfahren in der psychiatrischen Praxis weitestgehend unbekannt. In dieser systematischen Übersicht identifizieren und diskutieren wir deshalb die aktuellsten Studien zu VNS bei TRD sowie Empfehlungen von Fachgesellschaften und diskutieren den Einsatz der VNS in der klinischen Praxis. In den letzten fünf Jahren wurden fünf Studien mit Evidenzgrad 2 und vier Studien mit Evidenzgrad 3 zu der Wirkung von VNS bei TRD-Patienten publiziert. Kurzfristige Wirksamkeit der VNS konnte in klinischen Studien nicht gezeigt werden. Mehrere Studien demonstrieren die Langzeitwirksamkeit der VNS. Die kürzlich publizierte größte Untersuchung der Thematik bestätigt signifikant bessere Behandlungsergebnisse bei Patienten, die eine Zusatztherapie mit VNS erhielten – im Vergleich zu Patienten, die nur Behandlung nach Goldstandard über fünf Jahre erhielten. Die langfristige Wirksamkeit der VNS bei TRD-Patienten ist mit Evidenz des Grades 2 belegt, jedoch ist es unklar, welche TRD-Patienten die höchste Wahrscheinlichkeit eines Ansprechens auf VNS haben, was die Patientenselektion in der Praxis erschweren kann. Zusätzlich wirkt sich möglicherweise die unklare und variable Definition der therapieresistenten Depression problematisch auf den rechtzeitigen Einsatz von Neurostimulationsverfahren aus.

AUTOMATED STUDENT ASSESSMENT: LABEL RECOGNITION IN STEM FIGURES

Visual representations such as Free body diagrams are an important part of solving engineering mechanics problems. Automatic Assessment of these types of images is difficult due to the involvement of multiple object types and to their contextual nature. Using a probabilistic approach, an algorithm was created to automatically categorize groups of characters in labels from images into specific object types including: variables, assignment operators, values, units, or words. Using these categories, the algorithm was then able to determine whether the label was an identifier, a point, a dimension, a variable definition, or an equation. A series of representative test cases were chosen and results found that the current algorithm was able to correctly predict the results of all test cases. The paper discusses each step in detail and provides the resulting probability coefficients for the model.

Against “Transracialism”: Revisiting the Debate

This article critically reflects on some of the themes and assumptions at stake in the “transracialism” controversy, and connects them to important works in critical race theory: namely Rey Chow's notion of “coercive mimeticism” and Sara Ahmed's critique of white liberal multiculturalism. It argues that the analytic account of “race” that Tuvel draws upon in her article—Sally Haslanger's—is politically problematic, both on its own terms and in light of broader reflections on racialized and gendered power relations. In particular, I critique Haslanger's assumption that all racial identities exist on the same conceptual plane: that a single variable definition of “race” can be applied to any particular racialized group—including white and nonwhite racial identities. This erases racialized power relations, especially where, in liberal “multicultural” nations, whiteness constitutes the implied standard against which an appearance of “racial difference” is conjured. Finally, I extend my argument to the issue of treating “race” and gender analogously. Rejecting this move, I propose an alternative way of conceptualizing these as analytically distinct, yet constitutively interdependent, phenomena. In order to situate the debate historically, I consider an example of “racial transgression” from twentieth‐century China.

Opini Publik di Media Sosial: Analisis Isi Opini Kandidat Ahok-Djarot dan Anies-Sandi di Twitter

Social networking sites are considered an important channel for expressing opinions and actively participating in political life. Jakarta 2017 election into the spotlight when Basuki Tjahja Purnama or Ahok allegedly defamed the religion of Islam. In the first round, Agus-Sylvi pair must accept defeat and the couple Ahok-Djarot and Anies-Sandi go to the second round of 2017 Regional Head Election of Jakarta. On April 12, 2017, KPUD DKI Jakarta held the last debate discussing the problems and the exposure of work program which has been diserausn by both candidates based on the hashtag #DebatPilkadaDKI. The purpose of this study is to know the direction of opinion Ahok-Djarot candidates and Anies-Passwords on the hashtag #DebatPilkadaDKI as well as the process of forming public opinion. This research uses three concepts are public opinion, social media twitter, and candidate debate. The paradigm used is positivism, quantitative research, descriptive research type, unit analysis using thematic analysis unit (pro, contra, and neutral categorization), variable definition is public opinion variable and social media twitter, analysis model is content analysis, opinion and social media twitter, population and sample that is random sampling, data collecting technique that is documentation, research instrument is sheet coding, data analysis technique using formula percentage, and validity and reliability of data using inter-coder reliability. The results of this study indicate that the pair Ahok-Djarot opinion direction in the last debate tend to be positive than the couple Anies-Sandi.
