On rank-based effectiveness measures and optimization   总被引：1，自引：0，他引：1  

Stephen Robertson  Hugo Zaragoza 《Information Retrieval》2007,10(3):321-339

Many current retrieval models and scoring functions contain free parameters which need to be set—ideally, optimized. The process of optimization normally involves some training corpus of the usual document-query-relevance judgement type, and some choice of measure that is to be optimized. The paper proposes a way to think about the process of exploring the space of parameter values, and how moving around in this space might be expected to affect different measures. One result, concerning local optima, is demonstrated for a range of rank-based evaluation measures.

Academic inbreeding: exploring its characteristics and rationale in Japanese universities using a qualitative perspective     

Hugo Horta  Machi Sato  Akiyoshi Yonezawa 《Asia Pacific Education Review》2011,12(1):35-44

This study analyses why and how academic inbreeding as a recruitment practice continues to prevail in Japan, a country with a mature higher education system, where high rates of academic inbreeding endure in most of the research-oriented universities in spite of several higher education reforms. Based on a qualitative analysis, we disclose three characteristics that lead academics to become inbred at Japanese universities. One characteristic—the adoption of “open recruitment processes” in detriment of “closed recruitment processes”—changed over time, limiting academic inbreeding practices, but two other characteristics remained unchanged over time: the “one university learning experience” and the “concentration of doctoral supervisors at the same university”. These latter characteristics represent difficult challenges to be tackled as they are also traditional characteristics of the Japanese higher education system. The research also shows that academic inbreeding practices are a means to assure organizational stability and institutional identity, features perceived as important by Japanese universities. A central challenge for the Japanese universities is then to guarantee these features without needing to rely on academic inbreeding practices to obtain them. However, devising policies to meet this challenge calls for institutional will to change, proactive strategies and time.  相似文献

The methodological illumination of a blind spot: information and communication technology and international research team dynamics in a higher education research program     

David M. Hoffman  Brigida Blasi  Bojana Ćulum  Žarko Dragšić  Amy Ewen  Hugo Horta  Terhi Nokkala  Cecilia Rios-Aguilar 《Higher Education》2014,67(4):473-495

This self-ethnography complements the other articles in this special issue by spotlighting a set of key challenges facing international research teams. The study is focused on the relationship between information and communication technology (ICT)-based collaboration and research team dynamics. Our diverse team, drawn from researchers in five countries and three projects, argues that an ironic casualty of the powerful, global phenomena we study, is a lack of insight into what happens to generic research team dynamics, when groups are ‘stretched’ in terms of geographical distance, generations, cultural beliefs, values and norms, as well as disciplinary/specialist traditions. Good intentions are not sufficient to cope with these challenges. This is because of the emerging complexity inherent in many types of international, interdisciplinary fields of study and the complexity of the career trajectories needed to make these studies a reality. Our study underlines that there are no beliefs, values, norms and practices linked to research team dynamics, that hold across the current territory, generations, disciplines, cultures, organizations and individuals leading and conducting comparative studies—and even less reflection on the implications of this fact. Compounding this lack of awareness is a less-than-perfect understanding of the way in which ICT-based collaboration bears on research team dynamics. We assert that a holistic, critical, long-term approach to emerging insights into the global division of academic labor, serves our field better than folk psychology or the methodological parochialism that sustains convention at the expense of creativity. Careful consideration of emergent processes, relationships and linkages that explain how short-term cooperation—within projects—begins to make sense—over careers—illuminates key focal points, which, in turn qualitatively illuminates the way forward concerning conceptualization and problematization of our practice; and novel methodological routes available for those interested in attaining better outcomes, over the long term.  相似文献

Going places: exploring the impact of intra-sectoral mobility on research productivity and communication behaviors in Japanese academia     

Hugo Horta  Akiyoshi Yonezawa 《Asia Pacific Education Review》2013,14(4):537-547

This study analyzes the impact of intra-sectoral mobility of academics on research productivity and R&D information exchange dynamics in Japan. The analysis shows intra-sectoral mobility impacting positively both research productivity and information exchange dynamics, but that this effect—except for information exchange with peers based abroad—has a threshold. This result highlights the importance of academic job mobility but also alerts for cases of “overloads of mobility,” leading us to argue for some degree of stability in academic careers, supported by policies fostering temporary international mobility spells. We also find that the role of foreign academics in the Japanese higher education is one of national and international gatekeepers being this role shaped by where the doctorate was obtained (Japan vs abroad). Japanese academics that have performed the doctorate abroad are also key international gatekeepers.  相似文献   

Internet,Multimedia and Virtual Laboratories in a 'Third World' Environment     

Julián Antonio Monge-Nájera  Marta Rivas Rossi  Víctor Hugo Méndez-Estrada 《Open Learning》2013,28(3):279-290

Electronic education faces similar difficulties in low-budget institutions throughout the world (many of them in common with developed nations), including mainly rejection or disinterest from staff and students, insufficient funds, outdated hardware, incompatible software and poor Internet access. Over the past five years, with low budgets and considerable limitations in the equipment available, the Universidad Estatal a Distancia in Costa Rica has produced multimedia courses and materials for use on the Internet, as well as designing virtual laboratories that can be run on cheap computers. The authors recount their experiences in the hope that these will prove useful to others. They explain how simultaneous production of traditional materials (mainly printed textbooks) and online courses, together with simple automatic evaluation and 'outsourcing', reduce costs significantly. They conclude that HTML and JAVA are currently the choice computer languages to reach the greatest number of users without need of a specific computing platform, powerful computers or expensive software.  相似文献   

Self-Determination and Goal Aspirations: African American and Latino Males’ Perceptions of Their Persistence in Community College Basic and Transfer-Level Writing Courses     

María de Lourdes Villarreal  Hugo A. García 《Community College Journal of Research & Practice》2016,40(10):838-853

This Grounded Theory study utilized Self-determination Theory to analyze the interview results of 18 community college African American and Latino males. The goal was to learn what helped participants to succeed and persist in developmental and transfer-level writing courses despite the obstacles that they faced. Three major themes emerged: (a) Male students of color continued to take and complete English courses because they were determined to achieve their academic goals; (b) they sought assistance and guidance from their English professors, from the writing lab attached to the basic skills course and from the writing tutoring staff; and (c) when they felt overwhelmed and considered dropping their English classes, their determination to achieve their goals and the assistance they received from faculty and other writing staff ultimately kept them from doing so. Therefore, first, community colleges should encourage students’ ability to be autonomous. Second, they can help students develop a sense of relatedness by providing a better sense of belonging. Third, institutions should develop strong faculty networks within the college to increase student motivation and self-determination by providing mentoring opportunities. Finally, institutions should consider utilizing faculty and other institutional agents to help students by providing information regarding various student support services that may help address issues students may be encountering.  相似文献   

A questionnaire for listening to students’ voices in the assessment of teaching quality in a classical medical school     

Maria Filomena Gaspar  Anabela Mota Pinto  Hugo Camilo F. da Conceição  José António Pereira da Silva 《Assessment & Evaluation in Higher Education》2008,33(4):445-453

The purpose of this study was to develop a teaching quality assessment questionnaire and assess its reliability by using it with a sample of first‐year medical students. Principal components analysis with varimax orthogonal rotation resulted in the development of a 12‐item, two‐component tool, adequate for use in lectures and small‐group sessions. The two components were named ‘curriculum’ and ‘relationship’. The Cronbach coefficient alpha values indicated high reliability and internal consistency. According to the results obtained this teaching quality scale is a reliable measure and may be useful in identifying themes in disciplines and among teachers that may benefit from some professional development. Amongst its advantages is that it can be used with an optical reading tool.  相似文献
