    Urban sprawl phenomenon and farther away someone travels every day causes a role of travel time to impact daily activities. Transportation or travel is also considered as one of the factors relevant to well-being. Through Activity-Based Approach modeling, this study tries to analyze the level of travel satisfaction. The level of activity satisfaction conducted before and before traveling is expected to influence travel satisfaction significantly. The data used is Bandung Metropolitan Area (BMA) 2017, consisting of one week’s activity diary and daily trips. Ordinal logistic regression was used by modeling travel satisfaction using a Likert scale of 1 to 7. The study results indicate that activity satisfaction before and after travel and activity envelopes simultaneously significantly affect travel satisfaction. The participation of others during the trip positively correlates with travel satisfaction. Sociodemographic variables and time allocation for daily activities and travel have no significant effect on travel satisfaction. This study reveals that the measurement of travel satisfaction that does not take into account activities before and after traveling will impact the estimation of travel satisfaction being less precise.Semakin berkembang suatu daerah perkotaan dan semakin jauh seseorang untuk melakukan perjalanan harian mengakibatkan peranan waktu perjalanan semakin besar terhadap aktivitas sehari-hari. Transportasi atau perjalanan juga telah dianggap sebagai salah satu faktor yang relevan dengan kesejahteraan. Melalui pemodelan perencanaan transportasi berbasis aktivitas (Activity Based Approach), penelitian ini mencoba melakukan analisis tingkat kepuasan perjalanan (travel satisfaction) seseorang. Tingkat kepuasan aktivitas (activity satisfaction) tepat sebelum dan sesudah melakukan perjalanan diharapkan memiliki pengaruh yang signifikan terhadap kepuasan perjalanan. Data yang digunakan adalah data Bandung Metropolitan Area (BMA) 2017 yang terdiri atas data diari aktivitas dan perjalanan harian selama satu minggu. Metode yang digunakan adalah regresi logistik ordinal (ordinal logistic regression) untuk memodelkan kepuasan perjalanan dalam bentuk skala likert 1 s.d. 7. Hasil menunjukkan faktor kepuasan aktivtas sebelum dan sesudah melakukan perjalanan dan activity envelopes secara bersamaan memiliki pengaruh yang signifikan terhadap kepuasan perjalanan seseorang. Keikutsertaan orang lain selama perjalanan ditemukan memiliki korelasi yang positif terhadap kepuasan perjalanan. Variabel alokasi pola waktu aktivitas dan perjalanan sehari-hari serta kondisi sosiodemografi tidak berpengaruh signifikan terhadap kepuasan perjalanan. Penelitian ini mengungkapkan pengukuran kepuasan perjalanan yang tidak memperhitungkan aktivitas sebelum dan sesudah melakukan perjalanan akan berdampak pada estimasi kepuasan perjalanan menjadi kurang tepat.84 HalamanTesis Magiste

    The complexity and variability of individuals' activity-travel patterns in Indonesia

    Considering an individual’s day-to-day variability of activity-travel patterns will provide a more complete description of how an individual behaves to adapt the changing constraints and resources on different days. Without this day-to-day variability understanding, the individual’s behaviour would not be fully grasped and any suggested policy, planning and development would not completely achieve their desired objectives. The day-to-day behaviour is a subject to an interaction between individual’s needs and time-space constraints. The availability of ‘external’ resources (e.g., disposable income, built environment accessibility, and access to different travel mode/s) gives more opportunities for some individuals to participate in certain activities and/or trips than others. The constraints do not only consider budget and time constraints, but also include how an individual associates with other individuals and materials, and complies with any given authorities’ rules and regulations. The needs-constraints interaction also unveils some endogeneities which may not be captured by microeconomic and attitude theories. Failing to understand these interactions will underestimate the individual’s complex decision making process for performing certain behaviour. The constraints are not solely about physical constraints and instrumental factors, such as travel mode availability, time and cost. It is also influenced by individual’s non-instrumental variables, such as motivation, volition and habits. Currently there is a lack of knowledge how these non-instrumental variables are interacting and influencing the constraints to shape the individual’s travel behaviour. The implementation of certain activity-travel policy which only focuses in giving more opportunities to an individual within time and space resources without considering an individual’s attitude and/or habit may not be well accepted and followed by member of public. Moreover, the integration also reveals how an individual puts different priority on different potential activities based on the how an individual allocates/does not allocate time in engaging certain activities when having strong commitment and intention. In addition, including an individual’s health condition in the analysis may help in coordinating certain public health related policy with activity-travel policy. This thesis includes six papers which investigated the factors described above. The first three papers investigated how activity participation and built environment variables which can represent individuals’ constraints explain the day-to-day variability of individuals’ behaviours. Furthermore, the fourth and fifth paper explored the interaction between individuals’ time-use and activity participation, subjective characteristics and health factors. Lastly, the sixth paper examined how the time-space constraints and health condition explain the degree of variability in individuals’ multi-facet and multi-dimensional activity-travel patterns using sequential alignment method.  Genom att ta hänsyn till den dagliga variationen i en individs aktivitets- och resemönster erhålls en mer komplett bild av hur denna beter sig för att anpassa sig till ändrade begränsningar och resurser under olika dagar. Utan förståelse för denna dagliga variation kan inte individens beteende helt förstås och de föreslagna policyåtgärderna, planering eller utveckling skulle inte helt uppnå sina önskade mål. Det dagliga beteendet är föremål för en interaktion mellan å ena sidan individens behov och å andra sidan begränsningar i tid och rum. Tillgång till ”externa” resurser (exempelvis disponibel inkomst eller tillgång till olika färdmedel) påverkar möjligheterna för individer att delta i aktiviteter och/eller resor. Begränsningarna gäller inte bara monetär budget eller tid, utan inkluderar även exempelvis fysisk miljö, regler och förordningar samt hur en individ kan associera med andra individer. Växelverkan mellan behov och begränsningar belyser och klargör även endogenitet som inte självklart kan fångas av mikroekonomiska och attitydteorier. Att inte ta hänsyn till dessa interaktioner kan vara att underskatta individens komplexa beslutfattandeprocess. Tid- och rumsbegränsningarna handlar uteslutande om fysiska begränsningar och instrumentella faktorer, såsom färdmedelstillgänglighet, färdtid och färdkostnad. Individens beteende påverkas även av enskilda icke-instrumentella variabler, såsom motivation, vilja och vanor. Vi har idag bristande kunskap om hur dessa icke-instrumentella variabler interagerar med och påverkar begränsningar för att forma individens resebeteende. Genomförandet av viss aktivitets- och resepolicyåtgärder som bara fokuserar på att ge fler möjligheter till en individ inom tid- och rumsresurser, utan att också ta hänsyn individens attityder och/eller vana, kan försvåra allmänhetens acceptans.  Vidare, genom att inkludera en persons hälsotillstånd i analysen kan vi få ökade insikter hur vi kan samordna hälsorelaterade policyåtgärder med aktivitets- och resepolicyåtgärder. Denna avhandling innehåller sex artiklar som undersöker de faktorer som beskrivs ovan. De tre första artiklarna undersöker dels hur begränsningarna enligt ovan förklarar den dagliga variationen av en individs aktivitetsmönster och aktivitetsrum, dels samspelet mellan en aktivitets varaktighet, den erforderliga restiden och aktivitetsrummet. De fjärde och femte artiklarna undersöker samspelet mellan individens tid- och rumsbegränsningar, subjektiva egenskaper och hälsobegränsningar. Slutligen, i den sjätte artikeln undersöks med hjälp av en metod för sekventiell gruppering (sequential alignment) hur tidsbegränsning, rumsbegränsning och hälsotillståndet förklarar variationen i individers mångfacetterade och flerdimensionella aktivitets- och resemönster.QC 20151210</p

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    Dispelling the Myths Behind First-author Citation Counts

    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods
