Published: March 2002

Comparison mechanisms have been implicated in the development of abstract, relational thought, including object categorization. D. Gentner and L. L. Namy (1999) found that comparing 2 perceptually similar category members yielded taxonomic categorization, whereas viewing a single member of the target category elicited shallower perceptual responding. The present experiments tested 2 predictions that follow from Gentner and Namy's (1999) model: (a) Comparison facilitates categorization only when the targets to be compared share relational commonalities, and (b) providing common labels for targets invites comparison, whereas providing conflicting labels deters it. Four-year-olds participated in a forced-choice task. They viewed 2 perceptually similar target objects and were asked to "find another one." Results suggest an important role for comparison in lexical and conceptual development.

Comparison of shank, rearfoot and forefoot coordination and its variability between runners with different strike patterns.

J Biomech

January 2025

School of Exercise and Health, Shanghai University of Sport, Hengren Rd. 200, Yangpu District, Shanghai 200438, China. Electronic address:

This study aims to compare shank, rearfoot and forefoot coordination and its variability between runners with habitual rearfoot strike (RFS) and non-RFS (NRFS). 58 healthy males participated in this study (32 RFS, 26 NRFS). Coordination patterns and variability were assessed for the shank, rearfoot, and forefoot segments using a modified vector coding technique during running.

(Aristolochiaceae), commonly known as the Brazilian Dutchman's pipe, is cultivated globally as an ornamental vine, admired for the unique shape of its large flowers. In our ongoing research into the chemical composition of , the ethanol extract from its seeds was fractionated using chromatographic techniques, resulting in the isolation and identification of allantoin, along with the lignans kobusin, eudesmin, and methylarctigenin. The fractions were further analysed by NMR and GC - EI/MS, employing a molecular networking approach and retention index comparison, which led to the annotation of four sterols, eleven aliphatic alcohols, one saturated fatty acid, two unsaturated fatty acids, ten esters of saturated fatty acids, ten esters of unsaturated fatty acids, and one lactone.

This was an original study that mainly explored the effect of probiotic therapy and personalized nursing on immune function in children with acute gastroenteritis. One hundred and twelve (112) children with acute gastroenteritis were selected and divided into an intervention group and a control group. The control group accepted omeprazole enteric-coated capsules and routine nursing.

Evidence-Based Medicine in Otolaryngology Part 17: A Qualitative Research Primer.

Otolaryngol Head Neck Surg

January 2025

Department of Otolaryngology-Head and Neck Surgery, Harvard Medical School, Boston, Massachusetts, USA.

As qualitative data analysis becomes more frequently applied within the fields of medicine and surgery, it is beneficial to expand our knowledge of the utility, methodology, and interpretation of these techniques. While qualitative research serves a distinct purpose and differs from quantitative research, both can be approached with diligence, with careful techniques that are similarly maintained and respected. In advance of this installment in the Evidence-Based Medicine in Otolaryngology series, we presented a comparison between qualitative and quantitative methods.

TiRobot-assisted versus freehand femoral neck system placement in the treatment of femoral neck fractures: a systematic review and meta-analysis.

J Robot Surg

January 2025

The Third Ward of Orthopaedic Department, General Hospital of Ningxia Medical University, 804 Shengli South Street, Hui Autonomous Region, Yinchuan, Ningxia, 750004, People's Republic of China.

The purpose of this study is to assess the safety and effectiveness of TiRobot-assisted treatment for femoral neck fractures, in comparison to traditional freehand treatment methods. Throughout the research process, we conducted an extensive literature search across numerous databases, including PubMed, EMBASE, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), CQVIP, and Wanfang. Based on the literature screening criteria, we selected six studies, encompassing 358 cases of femoral neck fracture patients, for this meta-analysis.
