Characteristics of personal health records: findings of the Medical Library Association/National Library of Medicine Joint Electronic Personal Health Record Task Force     

Dixie A Jones  Jean P Shipman  Daphne A Plaut  Catherine R Selden 《Journal of the Medical Library Association》2010,98(3):243-249

Objectives:

The Medical Library Association (MLA)/National Library of Medicine (NLM) Joint Electronic Personal Health Record Task Force examined the current state of personal health records (PHRs).

Methods:

A working definition of PHRs was formulated, and a database was built with fields for specified PHR characteristics. PHRs were identified and listed. Each task force member was assigned a portion of the list for data gathering. Findings were recorded in the database.

Results:

Of the 117 PHRs identified, 91 were viable. Almost half were standalone products. A number used national standards for nomenclature and/or record structure. Less than half were mobile device enabled. Some were publicly available, and others were offered only to enrollees of particular health plans or employees at particular institutions. A few were targeted to special health conditions.

Conclusions:

The PHR field is very dynamic. While most PHR products have some common elements, their features can vary. PHRs can link their users with librarians and information resources. MLA and NLM have taken an active role in making this connection and in encouraging librarians to assume this assistance role with PHRs.

Highlights

• A variety of personal health records (PHRs) exist with some tied to medical health records and others offered as standalone products.
• Librarians can be connected to PHR users through inclusion of an assistance statement in PHRs.
• PHRs offer librarians another means of providing consumers with quality health information.

Implications

• PHR user support is a new role for medical librarians.
• Medical librarians need to be proactive in their communities to educate consumers about PHRs.
• Given the dynamic nature of this market, medical librarians should make a concerted effort to stay abreast of trends in this area.

Effect of geometry on the performance of MEMS aluminum nitride trampoline resonators in longitudinal resonance     

Annie Ruimi  Yueming Liang  Robert M. McMeeking 《Journal of The Franklin Institute》2012,349(7):2294-2312

The performance of a microscale aluminum nitride piezoelectric resonator in the shape of a trampoline is analyzed using three-dimensional finite element simulations. The air-suspended resonator is supported by beams and is designed to respond to longitudinal through-thickness vibrations. The device is targeted to operate at UHF frequencies (3 GHz) suitable for wireless filtering applications. Energy loss due to material damping is accounted for in the model. Other sources of damping are considered. We analyze if and how the material thickness, number of beams and beam length affect the resonator performance. This is intended to provide useful information at the design stages and eliminate the high costs associated with manufacturing a filter with poor performance. Performance is evaluated by means of the electromechanical coupling coefficient (K²) and the quality factor (Q) calculated from the electrical impedance frequency response plots. The results indicate that (i) K² is insensitive to geometry (K²～6.5%), (ii) Q increases linearly with the AlN thickness attaining Q～1900 for a 1.7 μm thick resonator and (iii) a trampoline resonator with three beams has a better performance capability than the resonator with four or eight beams with a figure of merit K²Q～120 and resonating at a higher frequency value than its counterparts resonators, peaking at 3.21 GHz. The performance figures agree well with those predicted by a one dimensional theory. The value of K² also agrees well with test data but that of Q is higher than the one recorded in the lab.  相似文献   

Relations between physiological and cognitive regulatory systems: infant sleep regulation and subsequent executive functioning   总被引：1，自引：0，他引：1  

Bernier A  Carlson SM  Bordeleau S  Carrier J 《Child development》2010,81(6):1739-1752

The aim of this report was to investigate the prospective links between infant sleep regulation and subsequent executive functioning (EF). The authors assessed sleep regulation through a parent sleep diary when children were 12 and 18 months old (N = 60). Child EF was assessed at 18 and 26 months of age. Higher proportions of total sleep occurring at night time, at both 12 and 18 months, were related to better performance on executive tasks, especially those involving a strong impulse control component. Most relations held above family socioeconomic status, prior mental development and concurrent verbal ability. These findings add to previous results with school-age children in suggesting that sleep favors the development of higher order cognitive functions requiring prefrontal cortex involvement.  相似文献

Decoding and sight-word naming: Are they independent components of word recognition skill?     

Aaron  P. G.  Joshi  R. M.  Ayotollah  Mahboobeh  Ellsberry  Annie  Henderson  Janet  Lindsey  Kim 《Reading and writing》1999,11(2):89-127

Word recognition skill is the foundation of the reading process. Word recognition could be accomplished by two major strategies: phonological decoding and sight-word reading, the latter being a marker for proficient reading. There is, however, a controversy regarding the relationship between decoding and sight-word reading, whether the two are independent or the latter is built on the foundations of the former. A related controversy about instructional strategy could be whether to use whole-word method to improve word recognition skills, or to first build decoding skills and then introduce sight words. Five goals were set up to address these issues: (a) developing a criterion that can be used easily by classroom teachers to assess sight-word reading ability, (b) examining this relationship between decoding and sight-word reading, (c) identifying the mechanism that can explain the relationship, (d) examining factors that facilitate sight-word reading, and (e) discussing potential instructional implications of these findings. In order to accomplish these goals, naming time and word-naming accuracy of three groups of subjects (elementary school children, children identified as having reading disability, and college students) were studied by using a variety of verbal materials. The over-all conclusions are that the difference in naming time of letters and words can be used as a metric for assessing sight-word reading skill. Sight-word reading appears to be intimately related to decoding. Sight-word reading is accomplished by parallel processing of constituent letters of words and is influenced also by the semantic nature of words. It is conjectured that sight-word reading instruction is likely to be successful if decoding skills are firmly established first.  相似文献

Socialization experiences and coping strategies of adults raised using spoken language     

Bain L  Scott S  Steinberg AG 《Journal of deaf studies and deaf education》2004,9(1):120-128

This investigation concerned the socialization experiences and coping strategies of a group of 28 deaf adults who were raised using spoken language. Most respondents reported some level of social isolation because of (1) limitations in communication with hearing peers; (2) missing information in social, academic, and work settings; and (3) a sense of being "different." Most participants also reported strategies used to reduce isolation and mitigate the social difficulties associated with their hearing loss.  相似文献   

Sensory integration in the learning of aiming toward "self-defined" targets     

Robin C  Toussaint L  Blandin Y  Vinter A 《Research quarterly for exercise and sport》2004,75(4):381-387

This study aimed at supporting the specificity of learning hypothesis, when aiming was based on internal cues, as directing the hand toward a "self-defined" target location. Participants practiced modest (20 trials) or intensive (720 trials) training with visual and proprioceptive information or proprioceptive information only. Pretests and posttests were performed in sensory conditions that did or did not match the training condition. Results showed that dynamic visual cues played a dominant role at the beginning of the task, and an intensive practice resulted in increased accuracy of kinesthetic information and efferent mechanisms of motor responses. These results have implications with regard to motor learning conceptions and training as a function of the task constraints.  相似文献
