How Congested Jakarta is? Perception of Jakarta’s Citizen on Traffic Congestion
No full textThis paper aims to reveal the behavior and perception of Jakarta\u27s citizens on traffic congestion in Jakarta. Although this approach is somewhat well-developed in behavioral science, its utilization in urban economics study, is still limited. Detecting the traffic congestion and its cause mainly relies on physical (engineering) methods, i.e V/C ratio. Here, we define the traffic congestion through two variables; ordinal traffic congestion perception and proportion of expected travel time to perceived travel time. Using a non-probabilistic sampling survey held in one of densest business district in Jakarta called Sudirman-Thamrin Golden Triangle Area; the estimation results show that travel behavior plays a major role in affecting travel time perceptions
Pengaruh Larangan Ekspor Karang Hias terhadap Kondisi Terumbu Karang di Indonesia
No full textIndonesia has the largest coral population in the world, contributed as the world’s second largest ornamental corals exporter after Japan. Coral trade sparked the issues of habitat destruction, illegal trade, and coral health problems has prompted the government to banning of ornamental coral export. This study aims to find an empirical evidence does the policies mentioned above affect the condition of coral reefs in Indonesia. The author uses the Fixed-Effect Model on the Difference in Difference regression equation whose result show that export banning of ornamental corals does not significantly affect the condition of coral reefs in Indonesia
Pengaruh Asset Life Cycle Management terhadap Performa Aset Negara
No full textThis study examines the impact of government intervention in asset management systems on the performance of state-owned assets. Using Asset Life Cycle Management (ALCM) indicators and binary logistic regression, the findings reveal that three key aspects of ALCM—strategy and planning, acquisition, and operation and maintenance—significantly influence asset performance. The impact of ALCM policies varies by asset location, categorized into five major regions: Sumatra, Java, Kalimantan, Bali-Nusa Tenggara, and Papua. These results provide empirical evidence that effective asset management policies positively contribute to optimizing the performance of state assets
Dampak Pembangunan Jalan Tol Trans Jawa terhadap Perekonomian Daerah Kabupaten/Kota
Get PDFInfrastructure development is one of the driving wheels of economic that have potential to drive increased production, create jobs and reduce the number of poor people. One of the government\u27s focus on infrastructure is the construction of the Trans Java Toll Road that connects the entire Java Island from Jakarta to Surabaya. The purpose of this research is to analyze the impact of the operation of the Trans Java Toll Road which began in part since 2015, 2017, 2018 and 2019 on the Regency/Municipality economy, especially those passed by toll roads. The indicators of regional economy in this research are GRDP per capita, open unemployment rate, dan poverty rate. The research method used is Difference in Difference (DiD) in the form of Staggered Adoption Design (SAD) using 84 regency/municipality data spread across 6 provinces in Java Island from 2012-2919. Estimation results show that the operation of the Trans Java Toll Road has not yet had a stable impact on increasing GRDP per capita, decreasing unemployment rate and reducing poverty rate. The insignificance of the influence of the Trans Java Toll Road is suspected because the analysis is still conducted in the medium term, where generally the influence of the new toll road is seen in the long term
The Health Impacts from Living Near Economic Industrial Parks in Sumatera
No full textWhile the operation of industrial areas has positively contributed to local economic growth on Sumatra Island, it has also resulted in negative environmental and health impacts. These externalities have prompted government intervention to address the adverse effects. Previous research indicates the need for alternative methods to quantify the side effects of industrial operations. This study, using Podes data and the Two-Way Fixed Effect (TWFE) model, estimates the impact of industrial activities on local health, specifically examining the incidence of diarrheal outbreaks as a proxy indicator at the village level. The analysis finds that industrial activities are positively correlated with a 4.16% increase in the incidence of diarrheal outbreaks in villages located within a 0 to 10 km radius of industrial areas, with statistical significance at the 1% level
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
