Objective: The purpose of this study was to examine the surgical impact of the pedicled buccal fat pad (BFP) flap on the levator veli palatini (LVP) muscle and surrounding velopharyngeal (VP) anatomy following primary palatoplasty using magnetic resonance imaging (MRI). Design: Observational, prospective. Setting: MRI studies were completed at 3 different facilities. All participants with BFP flap were operated on by the same surgeon. Participants: Five pediatric participants with cleft palate with or without cleft lip (CP±L) who underwent primary palatoplasty with BFP flap placement. Comparison groups consisted of 10 participants: 5 with CP±L who did not receive the BFP flap and 5 healthy controls. Interventions: All participants underwent nonsedated MRI 2 to 5 years postoperatively. Main Outcomes and Measures: Anatomical measures of the velopharynx and LVP among the 3 participant groups. Results: Median values were significantly different among groups for velar length ( P = .042), effective velar length ( P = .048), effective VP ratio ( P = .046), LVP length ( P = .021), extravelar LVP length ( P = .009), and LVP origin–origin distance ( P = .030). Post hoc analysis revealed a statistically significant difference between the BFP and traditional repair groups for effective VP ratio ( P = .040), extravelar LVP length ( P = .033), and LVP length ( P = .022). Conclusions: This study provides preliminary support that the BFP flap creates a longer velum, with increased distance between the posterior hard palate and the LVP, and a larger effective VP ratio compared to traditional surgical techniques. Future research is needed to determine whether this procedure provides a more favorable mechanism for VP closure.

Active seating designs may enable users to move more frequently, thereby decreasing physiological risks associated with a sedentary lifestyle. In this preliminary study, two active seating designs (QOR360, Ariel; QOR360, Newton) were compared to a static chair (Herman Miller, Aeron) to understand how active vs. static seating may affect task performance, movement, posture, and perceived discomfort. This within-subjects experiment involved n = 11 student participants who sat upon each of the three chairs for 20 minutes while performing a series of computer-based tasks. Participants showed increased trunk movement while also reporting higher levels of perceived discomfort in the two active chair conditions. There was no significant difference in either posture or fine motor task performance between the active and static conditions. Future research may benefit from additional physiological measurements along with a wider variety of tasks that require seated users to make postural adjustments.

Research has not yet begun to investigate the practice or impact of school counselor assignment. A preliminary study sought to explore the nature and consequences of school counselor assignment practices in secondary schools. Secondary school counselors from one large Southeastern school district were asked to complete a questionnaire created for the purpose of this study. The results suggest a significant difference between school counselor assignment at the middle and high school levels. Middle schools predominantly utilized grade-level assignment while high schools used alphabetical assignment. Distinct advantages and challenges were indicated by school counselors from each assignment type. Implications for professional school counselors and future research directions are provided.

The purpose of this preliminary study was to assess lumbar multifidus, erector spinae, and quadratus lum-borum muscle activity during lifts as measured by changes in transverse relaxation time (T2) from magnetic resonance imaging (MRI). Thirteen healthy adults performed dynamic squat, stoop, and asymmetric stoop lifts at a standard load, with each lift followed by MRI. Increase in T2 for the multifidus and erector spinae was greater for the stoop than squat. No difference in T2 increase was noted between the multifidus and erector spinae for the squat or stoop. Increase in T2 for the contralateral multifidus was less for the asymmetric stoop than stoop. Future research using MRI and other biomechanical techniques is needed to fully characterize lumbar muscle activity during lifts for various populations, settings, postures, and loads.

Swallowing of amniotic fluid alters the volume of the fetal stomach; therefore an abnormal fetal stomach size can be indicative of pathology. Previous studies have used linear measurements on ultrasound to approximate stomach sizes. Fetal magnetic resonance imaging (MRI) allows for volumetric measurement of the stomach. The objective of this study was to develop a library of normal fetal stomach volumes on MRI at each gestational age. We also sought to measure stomach volumes of fetuses with esophageal atresia and compare to normal volumes at similar gestation ages (GA).  A retrospective review of fetal MRIs from patients 20-38 weeks GA was conducted.  Exclusion criteria for the controls included any impairment that would impede swallowing or alter stomach sizes.  Patients with esophageal atresia were identified and postnatal records were reviewed to confirm the diagnosis. The stomach volume was measured on T2-weighted imaging using Phillips Intellispace software. The stomach volumes of the controls at each GA were compared using one-way ANOVA with Games-Howell Post-Hoc (p<0.05).  The stomach volume in esophageal atresia was compared to controls using a T-test (p<0.001).    185 control studies, 10 at each week of gestation, and 8 patients with esophageal atresia were included. For normal fetuses, there was a trend of increased stomach size and broadened standard deviation with increasing GA.  No significant difference was found between any two sequential weeks, however the difference in second and third trimester volumes was significant (p<0.001).   The patients with esophageal atresia had significantly smaller stomach volumes compared to control patients of the same GA range (p<0.001).   This pilot study established reference values for fetal stomach volume, which was found to increase with GA. The stomach volume is significantly smaller in patients with esophageal atresia.  Thus, esophageal atresia can be identified prenatally, allowing for delivery at an appropriate acuity NICU and early intervention.

With the goal to form the hierarchical classification of the most important methodical exercises for teaching basic ski turn in ski schools and test differences between ski experts based on their different level of skiing education, there was conducted a survey on the total sample of 307 ski experts from different countries. Through the filling out the online survey they tried to distinguish the importance of the formed model of the most important methodical exercises for teaching basic ski turn. Expert model of the most important methodical exercises captured 6 variables: uphill turn and jumping into snowplough, basic turn with hand sideways, basic turn with clapping, ski poles in front, ski poles on neck, uphill turn with active ski guiding. In order to investigate the statistic meaning of differences in ranking the methodical exercises for teaching basic ski turn, participants are divided into three groups based on the degree of skiing education they posses. In relation to above mentioned, sums of ranks (∑R) of the most important methodical exercises for teaching basic ski turn have been calculated. Using non-parametric analogue post-hoc analysis, i.e. Kruskal-Wallis test (H-test) and appropriate empiric level of significance (p), statistic significance of sums of ranks (∑R) of the most important methodical exercises for teaching basic ski turn have been tested. Significant difference between the value of ranking the most methodical exercises have been obtained (H=138,62; p<0,001). Those variables which were not different in statistically significant way according to sums of rank were classified in one significant group, while variables which showed statistically significant difference were classified separately. Multiple statistically significant difference based on different degree ski education between the ski experts were not obvious. The results of this study provide an accurate and scientifically based methodological settings for teaching basic ski turn. This opens the directions for future research in the form of construction of measuring instruments whose application in practice should allow better selection and choice of modalities methodical exercises for training alpine skiers of different ages and levels of ski prior knowledge.

Purpose The purpose of this paper is to assess differences in banking service quality (BSQ) perceptions across demographic subgroups of Islamic and conventional Jordanian banking consumers. Design/methodology/approach Data are collected using surveys. The survey contains items for three different measures of overall BSQ perceptions. The researchers mailed surveys to a random sample of 2,000 banking customers in Jordan. Responses to questionnaire items measuring respondents’ BSQ perceptions were analysed using one-way analysis of variance with Tukey’s honest significant difference post hoc tests to assess subgroup differences in six demographic variables: gender, age, occupation, income, education, and religion. Findings BSQ perceptions are significantly different in four of the six demographic variables. Age and education do not impact on BSQ perceptions. Research limitations/implications The findings indicate demographic effects on Jordanian banking consumers’ perceived BSQ. Study limitations include demographic subgroup underrepresentation and survey structure. Future research should obtain a more representative sample for better generalisability. Practical implications The findings suggest that Jordanian banks should structure their services to best accommodate their customers’ demographics. In addition, banks can use the findings to guide the development of demographic-driven marketing to target and attract customers efficiently. Originality/value This study is the first to investigate demographic differences in the perceived service quality of Jordan’s Islamic and conventional banking customers. The findings can contribute to future research on BSQ, and guide Jordan’s banking management towards more effective marketing and service provision.

Mesenchymal stem cells (MSCs) can be harvested from different sites in the oral cavity, representing a reservoir of cells useful for regenerative purposes. As direct comparisons between at least two types of MSCs deriving from the same patient are surprisingly rare in scientific literature, we isolated and investigated the osteoinductive potential of dental pulp stem cells (DPSCs) and buccal fat pad stem cells (BFPSCs). MSCs were isolated from the third molar dental pulp and buccal fat pads of 12 patients. The number of viable cells was quantified through manual count. Proliferation and osteodifferentiation assays, flow cytometry analysis of cell phenotypes, and osteocalcin release in vitro were performed. The isolation of BFPSCs and DPSCs was successful in 7 out of 12 (58%) and 3 out of 12 (25%) of retrieved samples, respectively. The yield of cells expressing typical stem cell markers and the level of proliferation were higher in BFPSCs than in DPSCs. Both BFP-SCs and DPSCs differentiated into osteoblast-like cells and were able to release a mineralized matrix. The release of osteocalcin, albeit greater for BFPSCs, did not show any significant difference between BFPSCs and DPSCs. The yield of MSCs depends on their site of origin as well as on the protocol adopted for their isolation. Our data show that BFP is a valuable source for the derivation of MSCs that can be used for regenerative treatments.

The objective of the research was to identify statistically significant differences in selected engagement indicators on Facebook – likes and shares in relation to the different types of content that brands on this platform add to. The analysis was performed on a sample of three global companies from the top 25 most valuable brands in the world and their posts. Using quantitative statistical methods – MANOVA (Multivariate analysis of variance) and Gammes-Howell post hoc test, a total of 1,280 brand posts were analyzed in order to differentiate the liking and sharing of content types. Data collection was carried out in the first half of 2018. The findings pointed to two statistically significant differences that were also interpreted in the discussion of the research. The findings have shown that in case of liking, in two cases out of three, there is a statistically significant difference in terms of the type of content added, when photos came out as those with the greatest potential to get like from Facebook users and fans. At the same time, the same finding appeared in the case of sharing, which is an even stronger form of engagement. Likewise, photos were shown to be the most promising in terms of potential content sharing by Facebook users and fans. The study provided some clues as to where this research should go further and explore the relationship more deeply in view of the more extensive quantitative research, and also the potential qualitative approach. The future research directions include analyzing companies of different types and sizes and also taking into account the contribution from other social networks with the same or similar engagement indicators.
