Alighting location estimation from public transit data: a case study of Shenzhen
Get PDFThis study proposes a framework to estimate alighting locations from Smart Card Data (SCD) that are absent information on entry-only public transport systems such as buses and trams. The proposed method uses the characteristics of SCD to (i) determine boarding locations from SCD and GPS-bus data based on exact match and time windows using common attributes, (ii) infer individuals’ home locations and user types from multimodal SCD, (iii) estimate alighting locations using inferred information with different scenarios such as with and without home locations based on the type of users. Reliable results are obtained once home locations are identified with high confidence for all user types. The proposed framework is applied to Shenzhen, China as a case study to validate the proposed model's effectiveness. The study offers valuable insight into aligning location estimation from user types to optimise the quality of public transport planning and services
Re-framing devotion in the later Cinquecento: The Madonna di Mongiovino and Catholic reform
No full textThe proliferation of miracle-working images in Italy from the end of the fifteenth century on has been well documented, as has the concomitant emergence of the sanctuary church. Less attention, however, has been given to the fortune of these sites in the later sixteenth century, when the zeal they incited in local populations was viewed by Church authorities as a powerful tool for engaging the faithful at a pivotal time of Catholic renewal – if harnessed correctly. According to visitation reports, superstitious practices were not uncommon, and greater scrutiny was afforded to both new prodigies and established cults; but the Church hierarchy continued to defend the veneration of miraculous images, and the latter years of the Cinquecento saw the renovation of a number of key image shrines, including the focus of the current study. Situated in western Umbria, the Santuario di Mongiovino was the subject of an extensive decorative campaign during the 1560s-1580s, and involved artists, such as Niccolò Circignani, who would also work on papal projects in Rome. Drawing on a range of
textual sources, as well as a close analysis of the decorative re-framing of the cultic image, I argue that the iconographic programme employed at the site should be viewed in relation to contemporary debates around the use of religious imagery in
churches. In particular I posit that the concerns voiced in the written record at the time, whether in treatises or visitation reports, may also have informed the way in which miraculous images were presented to the faithful, resulting in solutions that helped to underline the Church’s position on the cult of saints, the role of images in devotion, and the primacy of Christ in the bestowing of grace

Coaching culture: an evidence review and framework for future research and practice
Get PDFGiven the colossal interest in creating ‘coaching cultures’, we update the 2014 literature review by Gormley and van Nieuwerburgh and extend this work by applying a Systematic Literature Review (SLR) methodology. In doing so, we detangle definitions and the conditions under which ‘coaching cultures’ can be developed. We also explore contemporary interventions, report on organisational level outcomes, and comment on how progress is measured and evaluated. In total, 1453 papers were identified using a systematic search, of which 42 met our initial screening criteria and nine were eligible for inclusion in our final review. Findings show that we remain with an unclear understanding of ‘coaching culture’; there is still no agreed definition and the building blocks (i.e., the foundational elements, interventions, outcomes, and measures) remain ambiguous. We recommend a framework for future research and practice and highlight a gap in our understanding of stakeholders’ behavioural and cultural patterns vis-à-vis the design and development of coaching culture programmes
How do firms shape their interactions with universities to build structural, human and relational capital? A mixed-method study of UK firms that interact with universities
Get PDFUniversities are considered a key source of external resources for firms. Firms’ choices regarding the form of collaboration and how potential universities are approached, strongly influence how their partnerships with universities develop and succeed. We investigate how firms’ objectives to build three types of intellectual capital influence their prevalent mode of entering into interactions with universities. Building on a survey of 190 UK-based firms, we make an original contribution by demonstrating positive associations between: (A) structural capital-building objectives (i.e. sourcing resources and technologies required for research and development), and institutional mode of entry (i.e. directly contacting institutions of the university), mediated by the perceived functionality of acquisition channels (i.e. unidirectional transfer of resources from universities to firms); (B) relational capital-building (i.e. improving visibility and reputation), and the perceived functionality of co-creation channels (i.e. close working relationship between universities and firms), which in turn is positively associated with the frequency of use of individual modes of entry (i.e. directly contacting academics); (C) human capital-building (i.e. sourcing knowledge and associated networks) and both institutional and individual modes, mediated by the perceived functionality of, respectively, acquisition and co-creation channels (the latter when the firm intends to build new human capital, the former when it intends to exploit existing capital);. Our findings offer practical implications regarding how firms enter into relationships with universities depending on the firms’ objectives
Mokken scale analysis of the Internet Gaming Disorder Scale–Short-Form and the Gaming Disorder Test
Get PDFIn recent years, research on Gaming Disorder (GD) has grown substantially with researchers developing different psychometric tools for assessing disordered gaming. Two of the most prominent tools are the Internet Gaming Disorder Scale–Short-Form (IGDS9-SF) and the Gaming Disorder Test (GDT), which assess disordered gaming under the American Psychiatric Association (APA) and the World Health Organisation (WHO) frameworks respectively. The main aim of this study was to assess and compare the scalability, reliability, and validity of both scales to determine if the tools effectively assess GD in a normative sample, through the Mokken Scale Analysis (MSA). A sample of 605 participants (42.31 % female, meanage = 23.98 years, SD = 9.21 years) was recruited for the present study. Results showed that both the IGDS9-SF and GDT were unidimensional, with all items presenting latent monotonicity fitting in the Monotone Homogeneity Model (MHM). Item characteristic curves did not intersect and presented with adequate fit in the Double Monotonicity Model (DMM). These findings further support the psychometric adequacy of the IGDS9-SF and GDT, attesting to their suitability to assess disordered gaming
Identifying and exploiting alpha in linear asset pricing models with strong, semi-strong, and latent factors
Get PDFThe risk premia of traded factors are the sum of factor means and a parameter vector we denote by which is identi ed from the cross-section regression of i on the vector of factor loadings, i. If is non-zero, then i are non-zero and one can construct "phi-portfolios" which exploit the systematic components of non-zero alpha. We show that for known values of i and when is non-zero there exist phi-portfolios that dominate mean-variance portfolios. The paper then proposes a two-step bias corrected estimator of and derives its asymptotic distribution allowing for idiosyncratic pricing errors, weak missing factors, and weak error crosssectional dependence. Small sample results from extensive Monte Carlo experiments show that the proposed estimator has the correct size with good power properties. The paper also provides an empirical application to a large number of U.S. securities with risk factors selected from a large number of potential risk factors according to their strength and constructs phi-portfolios and compares their Sharpe ratios to mean variance and S&P portfolios
Anonymity in dealer-to-customer markets
Get PDFWe use a laboratory experiment to explore the effect of a change in pre-trade anonymity in a quote-driven dealer-to-customer market, organised as a request for quote (RFQ). We consider two treatments in which dealers interact with two types of customers (Informed or Uninformed). In the first treatment, there is no anonymity: dealers know whether the customer that sent them the request for quote is informed or uninformed. In the second treatment, there is complete anonymity: dealers do not know the type of customers they are interacting with. We find that anonymity improves liquidity and price efficiency, whereas it does not adversely impact dealers’ trading profits. Our results contribute to the debate on transparency versus the adoption of anonymity in financial markets
