Authors: Kebritchi Mansureh , Hirumi Atsusi , Kappers Wendi , Henry Renee 
Published: May 2008

AbstractThis paper identifies resources to be included in a website designed to facilitate the integration of instructional games in K‐12 settings. Guidelines and supporting components are based on a survey of K‐12 educators who are integrating games, an analysis of existing instructional game websites, and summaries of literature on the use of educational software in K‐12 settings and teacher technology training. The results indicate that educators face three main challenges when integrating games, including: (1) curriculum integration, (2) technical and logistical requirements, and (3) teacher training. To overcome these challenges, K‐12 educators should be provided with: (1) curriculum resources, (2) game technical information and support, and (3) communication tools. Websites designed to facilitate the use of instructional games should be designed with appropriate structures (ie, grid, web, hierarchy) to optimise organisation and simplicity. In addition, the websites should include teacher training that (1) apply a teacher training model, (2) address National Educational Technology Standards, (3) present contents in small doses, (4) make training and information as accessible as possible, and (5) model and mentor the use of instructional games.
Paper‐based and computer‐based concept mappings: The effects on computer achievement, computer anxiety and computer attitude
Authors: Erdogan Yavuz 
Published: May 2008

AbstractThe purpose of this paper is to compare the effects of paper‐based and computer‐based concept mappings on computer hardware achievement, computer anxiety and computer attitude of the eight grade secondary school students. The students were randomly allocated to three groups and were given instruction on computer hardware. The teaching methods used for each group were the conventional method, paper‐based concept mapping and computer‐based concept mapping. At the end of a 4‐week instruction, posttests were administered to assess computer hardware achievement, computer anxiety and computer attitude of the students. The findings indicate that paper‐based and computer‐based concept mapping strategies produce better results than the conventional method. However, the effects of paper‐based and computer‐based concept mapping strategies were not significantly different.
Examining barriers in technology‐enhanced problem‐based learning: Using a performance support systems approach
Authors: Park Sung Hee , Ertmer Peggy A. 
Published: May 2008

AbstractThis study focused on the barriers that middle school teachers faced when implementing technology‐enhanced problem‐based learning (PBL) in their classrooms. Using a human performance‐based model, we interviewed teachers, administrators, university faculty and technical support staff to determine the perceived importance of multiple barriers to the implementation of technology‐enhanced PBL. Twenty‐one teachers, two school administrators and a project manager, two faculty members, and two technical support staff participated in the study. Interview data were supported by surveys, classroom observations and researchers' reflective journals. Results suggested that lack of a clear, shared vision was the primary barrier. Additional barriers included lack of knowledge and skills, unclear expectations and insufficient feedback. Recommendations to support teachers' efforts to integrate technology‐enhanced problem‐based learning are presented.
Thai American Women's Perceptions Regarding Mammography Participation
Authors: Clark Mary Jo , Natipagon‐Shah Bulaporn 
Published: May 2008

ABSTRACT
Objectives: To identify the factors influencing mammography screening among Thai immigrant women in Southern California.Background: Asian women have lower mammography screening rates than other U.S. women (Centers for Disease Control [CDC], 2007), and only 53% of Thai women in Los Angeles had a mammogram in the prior 2 years (Thai Community Development Center, 2004).Design: A phenomenological approach was used to elicit Thai immigrant women's perceptions of the reasons for screening participation. Phenomenology is an appropriate means of describing screening as experienced by members of a population for which there is little information. Focus groups were used to collect data to provide a group perspective.Sample: Thai women over 40 years of age in 2 Southern California counties were recruited at a local temple and a social services agency.Measurement: Participants were asked about mammography participation and to describe the factors that influenced screening for themselves, family members, and friends. Thematic analysis identified major themes.Results: Factors influencing mammography screening included knowledge, encouragement, health consciousness, physical factors, fear, cultural factors, social responsibilities, and logistical barriers.Conclusions: Participants identified factors amenable to nursing intervention that may influence mammography screening in this population. Further study is needed to determine the prevalence of these factors.

Authors: Resnick Barbara , Luisi Daria , Vogel Amanda 
Published: May 2008

ABSTRACT Objectives:To test the feasibility and effectiveness of the Senior Exercise Self‐efficacy Project (SESEP).Design:A feasibility study using a randomized control trial.Sample:The total sample included 166 persons, with a mean age of 73 years (SD=8.2 years), the majority of whom were female (81%), African American (72%), unmarried (86%), had at least a high school education (64%), and were retired (77%). There were 100 participants in the intervention group and 66 in the comparison group.Methods:The SESEP was a combined physical activity and efficacy‐enhancing intervention for community‐dwelling minority older adults. The primary outcomes included self‐efficacy, outcome expectations, exercise, and overall physical activity, and the secondary outcomes were mental and physical health‐related quality of life, depressive symptoms, pain, fear of falling, mobility, and chair rise time. Data were collected at baseline and following the 12‐week intervention.Results:There were statistically significant improvements in outcome expectations (p=.02), time spent in exercise (p=.04), and depressive symptoms (p=.02). Overall, there was a 77% rate of participation in classes.Conclusion:Although there was good participation in the SESEP among minority older adults, the primary outcomes were only minimally supported and there was even less support for the secondary outcomes.
Relationships Between Nurse‐ and Physician‐to‐Population Ratios and State Health Rankings
Authors: Bigbee Jeri L. 
Published: May 2008

ABSTRACT
Objective: To evaluate the relationship between nurse‐to‐population ratios and population health, as indicated by state health ranking, and to compare the findings with physician‐to‐population ratios.Design: Secondary analysis correlational design.Sample: The sample consisted of all 50 states in the United States. Data sources included the United Health Foundation's 2006 state health rankings, the 2004 National Sample Survey for Registered Nurses, and the U.S. Health Workforce Profile from the New York Center for Health Workforce Studies.Results: Significant relationships between nurse‐to‐population ratio and overall state health ranking (ρ=−.446, p=.001) and 11 of the 18 components of that ranking were found. Significant components included motor vehicle death rate, high school graduation rate, violent crime rate, infectious disease rate, percentage of children in poverty, percentage of uninsured residents, immunization rate, adequacy of prenatal care, number of poor mental health days, number of poor physical health days, and premature death rate, with higher nurse‐to‐population ratios associated with higher health rankings. Specialty (public health and school) nurse‐to‐population ratios were not as strongly related to state health ranking. Physician‐to‐population ratios were also significantly related to state health ranking, but were associated with different components than nurses.Conclusions: These findings suggest that greater nurses per capita may be uniquely associated with healthier communities; however, further multivariate research is needed.

Published: May 2008

Background.— Several studies were carried out to investigate the occurrence of headache attributed to acute stroke in patients with a lifetime history of migraine.Methods.— In a case–control series of 96 acute stroke patients with a lifetime history of migraine (M+) and 96 stroke patients without (M−), ischemic stroke patients only, without secondary infarction, were selected. The headache attributed to acute ischemic stroke was then analyzed.Results.— (M+) patients complained of headache more often than (M−) patients (P < .0001), mainly in the 24 hours before stroke onset (P < .0001). Migraine‐like features of headache were recognized in a greater proportion of cases in the (M+) patient group with ischemic stroke (P < .018). A preferential brainstem location of ischemic stroke in (M+) patients emerged compared with (M−) patients (P = .014).Discussion.— The high prevalence of headache attributed to stroke in (M+) patients, in a relevant proportion of cases presenting as a sentinel headache, suggests that cerebral ischemia lowers the threshold for head pain more easily in these “susceptible” patients. The most frequent involvement of the brainstem in (M+) patients with ischemic infarction concurs with recent reports that emphasized a greater headache frequency when cerebral infarctions are localized in this structure or deep brain gray matter.

SummaryPurpose:Incidental paradoxical antiepileptic effect of levetiracetam has been described. The aim of the present study was to identify the epilepsy patients at risk.Methods:We performed a retrospective analysis in 207 patients treated with levetiracetam. This entailed evaluation of patient notes and patient interviews. A paradoxical effect was defined as an increased seizure frequency or the experience of more severe seizures including generalized tonic–clonic seizures (GTCS) within 1 month after starting levetiracetam (LEV).Results:Thirty patients (14%) experienced a paradoxical effect. Eight of them (4%) developed de novo GTCS. We could not demonstrate any association between the paradoxical effect of levetiracetam and type of epilepsy or the antiepileptic comedication used. However we found that the paradoxical effect developed preferentially (p < 0.001) in mentally retarded patients.Conclusion:Because there is an increased risk of worsening epilepsy when starting levetiracetam treatment of mentally retarded epileptic patients, there is a need for caution and close observation during the first weeks of therapy.
Vigabatrin in the treatment of childhood epilepsy: A retrospective chart review of efficacy and safety profile
Authors: Camposano Susana E. , Major Philippe , Halpern Elkan , Thiele Elizabeth A. 
Published: May 2008

Summary
Purpose: To review the efficacy, cognitive outcome and safety profile in children treated with vigabatrin (VGB) for infantile spasms (IS) and partial epilepsies related to tuberous sclerosis complex (TSC) and other etiologies.
Methods: Retrospective review of children followed in the Pediatric Epilepsy Program of Massachusetts General Hospital for Children between May 2001 and March 2006 who were treated with VGB.
Results: Eighty‐four children were treated with VGB, 68 of them were treated for IS, and 59 were treated for partial seizures (PS). Etiology (TSC or other) was the only predictive factor for IS control with VGB (p < 0.0003). IS control was achieved in 73% of children with TSC and 27% of children with other etiologies (combined 56%). Partial onset seizures were controlled in 34% of all children, (17% seizure free,17%reduction in seizure frequency >
50%
) and no predictive factor was found. Shorter time from seizure onset to VGB treatment (p < 0.027) and longer total time on VGB (p < 0.045) was associated with better IQ‐
developmental quotient (
DQ) outcome in children treated for IS, but not with IS control. Adverse events were seen in 13%. Electroretinogram and/or behavioral visual field (VF) testing was done in 52%
. VGB was discontinued in one case due to abnormal electroretinogram (ERG) findings.
Conclusion: We confirm the efficacy of VGB in the treatment of IS and PS in an American population. VGB may improve cognitive outcome in the absence of complete IS control, but this finding is of uncertain clinical significance. VGB was well tolerated, and ophthalmologic side effects were uncommon.

SummaryAutosomal dominant nocturnal frontal lobe epilepsy (ADNFLE) is a relatively benign epilepsy syndrome with few comorbidities. Here we describe two families with unusually severe ADNFLE, with associated psychiatric, behavioral, and cognitive features. Detailed clinical data on 17 affected individuals were obtained, and genotyping of microsatellite markers, linkage analysis, and sequencing of candidate genes was performed. The severe ADNFLE phenotype in these families was often refractory to treatment, with status epilepticus occurring in 24% of subjects. Psychiatric or behavioral disorders occurred in 53%, with intellectual disability in 24%, and developmental regression in two individuals. No mutations were identified in α4, α2, or β2 nAChR subunits. In one family there was evidence of linkage to a region of 15q24 without nAChR subunit genes. In conclusion, severe ADNFLE has significant medical, psychiatric, and intellectual morbidity. The molecular basis of severe ADNFLE is unknown but may involve non‐nAChR‐related mechanisms.
A comparison of emotional and cognitive intelligences in people with and without temporal lobe epilepsy
Authors: Walpole Pete , Isaac Claire L. , Reynders Hazel J. 
Published: May 2008

Summary Medial temporal lobe structures have been hypothesized to be important in emotional intelligence (EI) and social cognition. There is some evidence associating temporal lobe epilepsy (TLE) with impairments in social cognition. This study aimed to establish whether TLE is also associated with deficits in EI. Sixteen patients with TLE and 14 controls without epilepsy matched for age and current intelligence quotient were compared on measures of EI, recognition of facial expressions of emotion, and distress. Results indicated that patients with TLE showed both impaired EI and impaired recognition of facial expressions. They also reported greater psychological distress, which correlated negatively with EI. It is suggested that some of the psychosocial problems experienced by patients with TLE can be conceptualized as the consequences of deficits in EI, possibly resulting from epilepsy‐related disruption to medial temporal lobe functioning.

Published: May 2008

AbstractEdentulous patients with maxillary defects face a more challenging oral rehabilitation process than dentate patients. With the use of mini dental implants (MDIs), it is now possible to immediately increase obturator retention and stability. Implant patients can have a retentive obturator that enhances the overall efficacy of the prosthesis both in comfort and function.
Implant Planning and Placement Using Optical Scanning and Cone Beam CT Technology
Authors: Van Der Zel Jef M. 
Published: May 2008

AbstractThere is a growing interest in minimally invasive implant therapy as a standard prosthodontic treatment, providing complete restoration of occlusal function. A new treatment method (CADDIMA), which combines both computerized tomographic (CT) and optical laser‐scan data for planning and design of surgical guides, implant abutments, and prosthetic devices, is described. Imaging using a “NewTom 3G” cone beam CT scanner and a modified laser triangulation scanner “D200c” is discussed, as are impression and surgical guide fabrication, which allow for flapless, precise implant placement and an accurate provisional prosthesis. The new approach gives the operator full control over the design of the implant prosthesis for planning of proper occlusal relations and shows promise for further evaluation.

Published: May 2008

Abstract Purpose: A survey was distributed to the Harvard School of Dental Medicine (HSDM) predoctoral student classes of 2005 and 2006 to assess their perceptions regarding preclinical prosthodontics laboratory exercises. Prosthodontics curriculum clock hours, prosthodontics teaching participation, and plans for specialization were also analyzed. We hypothesized that reduced hours and perceived stress in the prosthodontics curriculum might impact students' choice of specialty at HSDM Materials and Methods: HSDM preclinical prosthodontics clock hours were compared with national means from published data. A survey was distributed to the HSDM classes of 2005 and 2006 (n = 70) at the end of their preclinical prosthodontics laboratory exercises, prior to students seeing their first patient in the clinics. Results: A 100% response rate was achieved. Results from this study show that HSDM preclinical prosthodontics clock hours are on average shorter than other schools. The majority of the students felt stressed during the laboratory exercises, and they felt they did not gain adequate knowledge from the lectures, resulting in low self‐esteem (confidence) in treating patients in the clinic. Despite this perception, HSDM students do just as well, if not better, than other students, as judged by external and internal outcome measures. Graduate prosthodontics specialization is still a specialty of choice among the graduates when compared to national data. Conclusions: The shortened preclinical didactic and laboratory exercises in prosthodontics at HSDM affect student anxiety, but not their didactic and clinical performances or their decisions in choosing their graduate program. Problem‐based learning (PBL) tutorials help the students to integrate preclinical and clinical knowledge and skills in prosthodontics.

Published: May 2008

▪ AbstractObjective: To validate CHIPPS (Children's and Infants' Postoperative Pain Scale) in Brazilian children.Background: Cross‐validation is needed in order to apply this scale in a different language and culture.Methods: We applied a Portuguese version of CHIPPS to 100 children aged 0 to 5 years. The scale was translated and tested for inter‐rater reliability, internal consistency, and construct, content, and concurrent validity. The children's behavior was videotaped before, during and after a procedure in a primary care unit. Three observers then rated pain behavior from videotapes.Results: The scale showed excellent inter‐rater reliability (intraclass correlation coefficient: 0.89) and a very good internal consistency, with Cronbach's alpha of 0.86. The positive correlation between CHIPPS and Modified Behavior Pain Scale supports concurrent (criterion) validity (Spearman coefficient 0.70 before and 0.81 after vaccinations). Construct validity was determined by comparing the scores of each child before vaccination (without pain) and during the procedure (experiencing pain), and the difference in pain scores was statistically significant (Wilcoxon signed rank test;P < 0.001). Content validity (by expert review) was very good.Conclusions: Based on the results obtained, we can infer that CHIPPS is a valid and reliable tool for Brazilian children aged 0 to 5 years old. ▪
COMMENTARY: Silver Bullet Junkies and the Codifiers That Love Them: Behavioral Roots Behind a Legacy of Bad Modeling and Use
Authors: Bendoly Elliot , Speier Cheri 
Published: May 2008

ABSTRACTAs research continues to evolve, it is important to look back with a critical eye on its impact on practice and what is guiding its trajectory into the future. In this work we discuss some of the key behavioral drivers that taken as a whole have made for a less than ideal relationship between research, model development, and use/reliance in practice. From a general public‐good perspective, there is an obvious need for academics to take on a greater role of responsibility when it comes to both research and curriculum in an effort to avoid some of the failings that our past work has inevitably encouraged to date.
The Effects of Process and Outcome Similarity on Users' Evaluations of Decision Aids*

Published: May 2008

ABSTRACTDecision aids (DA) used in online shopping contexts have been shown to improve users' product choices. Given that previous research (e.g.,Byrne & Griffitt, 1973) has demonstrated the positive effects of perceived similarity on an individual's evaluation of others, this study investigates the effects of users' perceived similarity with a DA on their evaluations of that DA. More specifically, we investigate the effect of users' perceptions of the similarity between their own decision process and that followed by the DA to arrive at a recommendation (decision process similarity), as well as the similarity between the recommendations made by the DA and users' initial choices (outcome similarity), on their evaluations of the DA's usefulness and trustworthiness. The results of this study show that perceived process similarity exerts positive and significant effects on users' perceptions of the DA's usefulness and trustworthiness. However, the effects of perceived outcome similarity on trust are completely mediated by perceived process similarity. It is also observed that the level of the user's domain knowledge moderates the effects of perceived decision process similarity on both perceived usefulness and trustworthiness. These results have implications for DA design. It is important that designers consider the process by which users make decisions for themselves and align the DA's decision process with those of the user's, especially for the novice user. The full mediation of the effect of outcome similarity on trust by process similarity highlights how a similar decision process can mitigate some of the negative effects of outcome dissimilarity.
