Queries submitted to search engines can be classified according to the user goals into three distinct categories: navigational, informational, and transactional. Such classification may be useful, for instance, as additional information for advertisement selection algorithms and for search engine ranking functions, among other possible applications. This paper presents a study about the impact of using several features extracted from the document collection and query logs on the task of automatically identifying the users’ goals behind their queries. We propose the use of new features not previously reported in literature and study their impact on the quality of the query classification task. Further, we study the impact of each feature on different web collections, showing that the choice of the best set of features may change according to the target collection. 相似文献

The Language for Professional Communication in Accounting project has changed teaching practice in a linguistically and culturally diverse postgraduate accounting program at Macquarie University in Australia. This paper reflects on the project’s interdisciplinary and collaborative approach to diversity in the classroom by tracing its growth and development and describing the way in which it is supporting the integration of professional communication skills and discipline‐specific content within the Master of Accounting program. In particular, the paper demonstrates that discipline specialists working in a continuous and collaborative relationship with English language specialists, to integrate and assess communication skills and enrich the curriculum, leads to better outcomes for students and staff. The paper contributes to a growing literature on approaches that integrate particular graduate attributes into programs with diverse student populations, rather than bolt‐on interventions by language specialists that have limited outcomes. 相似文献

Two experiments evaluated history effects on induced and operant variability. College students typed three-digit sequences
on a computer keyboard. Sequence variability was induced (by no reinforcement or variation- independent reinforcement) or
reinforced (by variation- or repetition-dependent reinforcement). Conditions with induced and operant variability were presented
according to a reverse between-groups design. In Experiment 1, we examined transitions from the variation or repetition contingencies
to no reinforcement, and vice versa. In Experiment 2, the variation or repetition contingencies were followed or preceded
by variation-independent reinforcement. The results showed that (1) a history of no reinforcement impaired operant variability
learning; (2) induced variability levels were higher and lower after a history of reinforcement for variation and repetition,
respectively; (3) repetition was more easily disrupted by no reinforcement and independent reinforcement than was variation;
and (4) response variability and stability were a function of past and current reinforcement conditions. These results indicate
that reinforcement history influences both induced and operant variability levels. 相似文献

This article explores commonalities in the lives and work of women head teachers in Malawian secondary schools and women principals in Australian Lutheran schools. In both Australia and Malawi women are under-represented in school leadership and often appointed to complex schools and communities. We commence with a brief discussion of Malawi and Australia’s political and educational histories which have much in common, before outlining current selection policies for school leadership. The second part of the article explores women leaders’ initial and ongoing challenges in relation to their school systems, daily work and domestic lives. The final section focuses on their perspectives of current strategies to address women’s under-representation as leaders in their respective school systems. Notwithstanding the stark contrast in socio-economic contexts, we highlight enduring transnational inequalities in women leaders’ lives and work in Malawian secondary and Australian Lutheran schools. 相似文献

The aim of this study was to analyze the effects of resistance training (RT) performed with 1 or 3 sets per exercise on osteosarcopenic obesity (OSO) syndrome parameters in older women. Sixty-two older women (68.0 ± 4.3 years, 26.8 ± 4.4 kg/m2) participated in a 12-week RT program. Participants were randomly assigned into one of the three groups: two training groups that performed either 1 set (G1S, n = 21) or 3 sets (G3S, n = 20) 3 times weekly, or a control group (CG, n = 21). Body composition was assessed by dual X-ray absorptiometry, strength was evaluated by 1 repetition maximum testing. The G3S presented significantly higher strength changes than G1S. The changes for percentage of body fat were higher for G3S compared to G1S. There was no difference in skeletal muscle mass between G3S and G1S, however both training groups displayed greater increases in this outcome compared to CG. There was no effect for bone mineral density. The overall analysis indicated higher (P < 0.05) positive changes for G3S than G1S (composed Z-score: G3S = 0.62 ± 0.40; G1S = 0.11 ± 0.48). The results suggest that a 12-week RT period is effective to improve the risk factors of OSO, and that 3 sets induce higher improvements than a single set. 相似文献

We investigated whether low-level laser therapy (LLLT) prior to or post resistance exercise could attenuate muscle damage and inflammation. Female Wistar rats were assigned to non-LLLT or LLLT groups. An 830-nm DMC Laser Photon III was used to irradiate their hind legs with 2J, 4J, and 8J doses. Irradiations were performed prior to or post (4J) resistance exercise bouts. Resistance exercise consisted of four maximum load climbs. The load work during a resistance exercise bout was similar between Control (non-LLLT, 225 ± 10 g), 2J (215 ± 8 g), 4J (210 ± 9 g), and 8J (226 ± 9 g) groups. Prior LLLT did not induce climbing performance improvement, but exposure to 4J irradiation resulted in lower blood lactate levels post-exercise. The 4J dose decreased creatine kinase and lactic dehydrogenase levels post-exercise regardless of the time of application. Moreover, 4-J irradiation exposure significantly attenuated tumor necrosis factor alpha, interleukin-6, interleukin-1β, cytokine-induced neutrophil chemoattractant-1, and monocyte chemoattractant protein-1. There was minor macrophage muscle infiltration in 4J-exposed rats. These data indicate that LLLT prior to or post resistance exercise can reduce muscle damage and inflammation, resulting in muscle recovery improvement. We attempted to determine an ideal LLLT dose for suitable results, wherein 4J irradiation exposure showed a significant protective role. 相似文献

The effects of running with or without shoes on injury prevention have been extensively studied, and several investigations have assessed biomechanical differences between them. However, findings are not consensual and further insights on biomechanical load associated with differently shod or barefoot conditions may be needed. This study aimed to observe if habitually shod marathon runners show acute alterations when running barefoot or with minimalist shoes, and to determine whether the running kinematical adaptations of wearing minimalist shoes were similar to barefoot running. Twelve male marathon runners ran on the treadmill at their average marathon pace in different footwear conditions: habitual running shoes, minimalist shoes, and barefoot. High-resolution infrared cameras and visual 3D software were used to assess kinematic data. The following parameters were studied: foot strike angle, cycle time, stance time, normalized stride length, hip, knee, and ankle angular position at initial contact, and their respective range-of-motion (ROM) during stance phase. Contrary to the expectations, it was found that highly trained habitually shod elite marathon runners changed their lower limb kinematic pattern both when running barefoot or wearing minimalist shoes. Minimalist shoes showed a trend towards intermediate biomechanical effects between running with and without shoes. 相似文献

This review critically appraised the literature on disability disclosure and accommodations for youth with disabilities in post-secondary education (PSE). Systematic searches of 8 databases identified 36 studies meeting our inclusion criteria. These studies were analysed with respect to the characteristics of the participants, methodology, results of the studies and quality of evidence. Five thousand, one hundred and seventy four participants (mean age 26.4) were represented across six countries. Barriers to disability disclosure and requests for accommodations in PSE included stigma, discrimination, lack of knowledge of supports and how to access them, type of course and instructor, coping styles, and nature of the disability. Facilitators included supports and resources, coping and self-advocacy skills, mentorship, and realising the benefits of disclosure. Factors affecting the process and timing of disability disclosure in PSE included the type of disability, and mode of disclosure. There was a lack of consensus on the timing of disclosure. 相似文献
