Urban vibrancy contributes towards a successful city and high-quality life for people as one of its vital elements. Therefore, the association between service facilities and vibrancy is crucial for urban managers to understand and improve city construction. Moreover, the rapid development of information and communications technology (ICT) allows researchers to easily and quickly collect a large volume of real-time data generated by people in daily life. In this study, against the background of emerging multi-source big data, we utilized Tencent location data as a proxy for 24-h vibrancy and adopted point-of-interest (POI) data to represent service facilities. An analysis framework integrated with ordinary least squares (OLS) and geographically and temporally weighted regression (GTWR) models is proposed to explore the spatiotemporal relationships between urban vibrancy and POI-based variables. Empirical results show that (1) spatiotemporal variations exist in the impact of service facilities on urban vibrancy across Guangzhou, China; and (2) GTWR models exhibit a higher degree of explanatory capacity on vibrancy than the OLS models. In addition, our results can assist urban planners to understand spatiotemporal patterns of urban vibrancy in a refined resolution, and to optimize the resource allocation and functional configuration of the city.

Abstract. This study explored city residents’ collective geo-tagged behaviors in response to rainstorms using the number of location request (NLR) data generated by smartphone users. We examined the rainstorms, flooding, NLR anomalies, as well as the associations among them in eight selected cities across the mainland China. The time series NLR clearly reflects cities’ general diurnal rhythm and the total NLR is moderately correlated with the total city population. Anomalies of NLR were identified at both the city and grid scale using the S-H-ESD method. Analysis results manifested that the NLR anomalies at the city and grid levels are well associated with rainstorms, indicating city residents request more location-based services (e.g. map navigation, car hailing, food delivery, etc.) when there is a rainstorm. However, sensitivity of the city residents’ collective geo-tagged behaviors in response to rainstorms varies in different cities as shown by different peak rainfall intensity thresholds. Significant high peak rainfall intensity tends to trigger city flooding, which lead to increased location-based requests as shown by positive anomalies on the time series NLR.

This study aims to analyze the positioning map of GSM mobile phone operators prepaid systems based on consumer perception in the city of Jember. The basis used to position cellular telephone operators is consumers' perceptions of the similarity of the determinant attributes consisting of products, prices, promotions, locations, processes, people, and physical evidence of each cell phone operator. The analysis technique is Multidimensional Scaling (MDS). This research was conducted by taking 60 respondents with a purposive sampling method. The data obtained were tested using MDS analysis to determine the reliability and validity, the results of positioning maps of GSM cell phone operators of prepaid systems (Telkomsel, Indosat, XL, 3, and AXIS) based on consumer perceptions, and the similarity of respondents' attitudes in providing ratings . Based on the results of the analysis there are differences in the position of each GSM cell phone operator prepaid system based on consumer perception and shows that the GSM cell phone operator of the AXIS prepaid system is the closest competitor or direct competitor of the Telkomsel brand, especially regarding promotion, location, and process. XL and Three operators do not have direct competitors (indirect competitors) because they have the biggest difference or clear and unique differentiation. Indosat operators do not have a strong or clear positioning, because they do not have many similarities and also do not have much difference with other operators in the minds of consumers. The results of the consistency test and the similarity of the respondents' attitudes also showed that the respondents did not have the same attitudes in assessing the similarity of the GSM prepaid cell phone operator.

Acoustic geo-sensing deals with the derivation of spatial information from audio data. Motivated by the rising field of sensing information in (smart) cities, we present current perspectives and a methodological update on the acoustic-based solution of recognition problems in a complex urban real-world scenario. In particular, we examine a static and a sequential approach for the automatic recognition of a cyclist's route between fixed endpoints, the route direction, and the route progress, solely based on the audio data recorded with a cell-phone attached to the cyclist. To this end, we introduce the freely available 'Graz Cell-phone Cycle Corpus extended' (GC3+) that consists of more than 25 h of GPS-annotated audio material recorded in the southern urban area of the city of Graz, Austria. Promising recognition results confirm basic feasibility of acoustic geo-sensing in an urban environment. The approach's theoretical potential of being generalised to support the solution of position tracking problems on a multi-dimensional urban grid gives reason for the implementation of acoustic geo-sensing methodology in a number of real-world applications.

Penelitian mengenai onomastika telah beberapa kali dilakukan. Lewat penelitian onomastika dapat dijelaskan penggunaan aspek kebahasaan dan aspek lain seperti sejarah dan budaya, kehidupan, motivasi, serta alasan motivasi dan tujuan penamaan tersebut. Penelitian ini bertujuan untuk mendeskripsikan aspek kehidupan pada sistem penamaan jalan di Yogyakarta sebagai bagian dari keistimewaan Daerah Istimewa Yogyakarta. Penelitian ini menggunakan desain penelitian deskriptif. Penelitian dibatasi pada Kota Yogyakarta yang memiliki data nama jalan secara formal. Data berupa nama-nama jalan. Sumber data berupa sumber data tertulis dan lisan. Teknik pengumpulan data dengan observasi, wawancara, dan pencatatan. Analisis data dengan kultural-historis. Validasi dilakukan dengan triangulasi data dan metode. Penelitian menemukan 26 aspek kehidupan yang selanjutnya dapat dikelompokkan menjadi 9 aspek kehidupan. Aspek-aspek tersebut meliputi aspek tumbuhan dan binatang, aspek tempat (asal-usul tempat, fungsi tempat, penanda tempat, dan arah tempat), aspek yang berhubungan dengan keraton (kerabat keraton, prajurit keraton, tempat tinggal pegawai keraton, senjata perang), aspek geografis (ciri-ciri geografis, gunung/sungai, dan fenomena alam), aspek profesi, aspek pahlawan dan tokoh, aspek harapan dan cita-cita, aspek nama wayang, dan aspek lainnya (aktivitas kerja, karakter, dan sifat). Kata kunci: nama jalan, aspek kehidupan, kultural-historis BACKGROUNDS OF THE LIFE ASPECTS ON THE ROAD NAMING SYSTEM IN YOGYAKARTA CITY: ANTHROPOLINGUISTIC STUDYAbstract              Research on onomastics has been conducted a number of times. Through onomastic research, road naming can be described in terms of the linguistic and other aspects such as history and culture, ways of life, and motives and objectives. This study is aimed at describing the aspects of life in the street naming system in Yogyakarta as part of the special features of the Yogyakarta Special Region. This study uses the descriptive research design. The research location in Yogyakarta is limited to the city of Yogyakarta which has formal road name data. Data are in the form of street names in the study location. Data sources are written and oral. Data collection techniques are observation, interview, and recording. Data analysis is cultural-historical. Validation is done by data and method triangulations. Results show 26 aspects of life grouped into 9. These aspects are related to plants and animals, places (origin, function, marker, and direction), palaces (family kinship, soldier troop, official residence, and war weapon), geography (feature, mountain/river, and natural phenomena), profession, hero and figure, hope and ideal, wayang figure, and other (work activity, character, and nature). Keywords: street names, aspects of life, cultural-historical aspect
