Methodological Difficulties

Two separate experiments are reported. They show the methodological difficulties and subsequent conceptual complications in Berkowitz's modified frustration-aggression theory and Zillman's theory of aggression. There was a marginally significant difference in the verbal measure of aggression favouring subjects aroused by frustration over subjects aroused by exercise, but not on the behavioral measure of aggression. Exp. II was conducted to test an alternative hypothesis, deduced from Fraisse's theory of emotion, which states that subjects respond more aggressively when confronted with unexpected than with expected annoyance. All six measures of aggression confirmed the hypothesis. The results of these two experiments indicate conceptual and methodological difficulties inherent in Berkowitz's modified frustration-aggression theory and Zillman's theory of aggression; they also suggest that Fraisse's theory of emotion presents a better model of aggression.

The Mean

Conventionally, the strength of toe plantar flexion (STPF) is measured in a seated position, in which not only the target toe joints but also the knee and particularly ankle joints, are usually restrained. We have developed an approach for the measurement of STPF which does not involve restraint and considers the interactions of adjacent joints of the lower extremities. This study aimed to evaluate this new approach and comparing with the seated approach. A thin, light-weight, rigid plate was attached to the sole of the foot in order to immobilize the toe area. Participants were 13 healthy young women (mean age: 24 ± 4 years). For measurement of STPF with the new approach, participants were instructed to stand, raise the device-wearing leg slightly, plantar flex the ankle, and push the sensor sheet with the toes to exert STPF. The sensor sheet of the F-scan II system was inserted between the foot sole and the plate. For measurement with the seated approach, participants were instructed to sit and push the sensor with the toes. They were required to maintain the hip, knee, and ankle joints at 90°. The mean values of maximum STPF of the 13 participants obtained with each approach were compared. There was no significant difference in mean value of maximum STPF when the two approaches were compared (new: 59 ± 23 N, seated: 47 ± 33 N). The coefficient of variation of maximum STPF was smaller for data obtained with the new approach (new: 39%, seated: 70%). Our simple approach enables measurement of STPF without the need for the restraints that are required for the conventional seated approach. These results suggest that the new approach is a valid method for measurement of STPF.

AbstractBackgroundThe comparability of thyroid-stimulating hormone (TSH) results cannot be easily obtained using SI-traceable reference measurement procedures (RPMs) or reference materials, whilst harmonization is more feasible. The aim of this study was to identify and validate a new approach for the harmonization of TSH results.MethodsPercentile normalization was applied to 125,419 TSH results, obtained from seven laboratories using three immunoassays (Access 3rd IS Thyrotropin, Beckman Coulter Diagnostics; Architect System, Abbott Diagnostics and Elecsys, Roche Diagnostics). Recalibration equations (RCAL) were derived by robust regressions using bootstrapped distribution. Two datasets, the first of 119 EQAs, the second of 610, 638 and 639 results from Access, Architect and Elecsys TSH results, respectively, were used to validate RCAL. A dataset of 142,821 TSH values was used to derive reference intervals (RIs) after applying RCAL.ResultsAccess, Abbott and Elecsys TSH distributions were significantly different (p < 0.001). RCAL intercepts and slopes were −0.003 and 0.984 for Access, 0.032 and 1.041 for Architect, −0.031 and 1.003 for Elecsys, respectively. Validation using EQAs showed that before and after RCAL, the coefficients of variation (CVs) or among-assay results decreased from 10.72% to 8.16%. The second validation dataset was used to test RCALs. The median of between-assay differences ranged from −0.0053 to 0.1955 mIU/L of TSH. Elecsys recalibrated to Access (and vice-versa) showed non-significant difference. TSH RI after RCAL resulted in 0.37–5.11 mIU/L overall, 0.49–4.96 mIU/L for females and 0.40–4.92 mIU/L for males. A significant difference across age classes was identified.ConclusionsPercentile normalization and robust regression are valuable tools for deriving RCALs and harmonizing TSH values.

Comfort is a key feature of any clothing that relates significantly to softness of the fiber, yarn and fabric from which is it constructed. A known softness assessment method for fibers is the resistance to compression test. This traditional test only provides a single force value for the resistance of a loose fiber sample using a fixed mass under compression. In this research, a modified resistance to compression test was introduced to show the effects of repeated compression, providing more information about the softness and resilience of selected fibers. Three different natural fiber types, including wool, cotton and alpaca were compared using this new approach. The results showed compression profiles were quite different for different fiber types as well as for the same fibers with different diameters. While the diameters of the wool and alpaca samples were similar (18.5 μm), the modified resistance to compression values were significantly higher for wool (with a peak value at 9.5 kPa compared to 2.1 kPa for alpaca). Cotton was different from wool and alpaca but showed a similar modified resistance to compression value (10.4 kPa) to wool. During cycles of compression, modified resistance to compression peak values decreased slightly and then tended to be constant. Even though the structures of wool, cotton and alpaca were quite different, there was no significant difference in the magnitude of decline in modified resistance to compression peak values. This means that the modified resistance to compression test is able to provide additional information on the resilience characteristics of different natural fibers, and can reveal the resistance behavior of fiber samples during cyclic compression.

Abstract PurposeTo compare and assess classic endoscopic dacryocystorhinostomy (cEDCR) and scopy-guided endoscopic dacryocystorhinostomy (sEDCR) which is a new approach we developed in cases of primary nasolacrimal duct obstruction (PNLDO).MethodsFifty eyes (7 in both eyes) of 43 patients who applied with epiphora and underwent endoscopic DCR and silicone tube implantation between 2015 and 2019 were prospectively studied. cEDCR was performed on 26 of 50 eyes, and sEDCR was performed on 24 of 50 eyes. In sEDCR application, 5 cc non-ionizing opaque material was injected after punctum dilatation, lateral oblique radiographs were taken from the obstructed side with C-arm scope, and the size and location of the lacrimal sac were made visible. Thence, the most appropriate part of the passage was visualized, and surgical intervention was made through this point. Patients were followed in day 1, week 1, 3rd and 6rd mounth. Functional success was assessed according to Munk scoring, and anatomic success was assessed with nasolacrimal lavage. Two groups were compared according to surgical success, time, and complications.ResultsMean age of the cases were 47.85 (±11.8) in the cEDCR group and 54.29 (±16.23) in the sEDCR group. Female and male gender distribution was 21 (80.8%) - 5 (19.2%) for cEDCR and 15 (62.5%) - 8 (37.5%) for sEDCR, respectively. Functional success was spotted as 92.3% in the cEDCR group and 95.8% in the sEDCR group (p:1.0); anatomical success was spotted as 88.5% in the cEDCR group, and 95.8% in the sEDCR group (p:0,611). There was no significant difference between two groups. Mean surgery time was 43 minutes in the cEDCR group and 48 minutes in the EDCR group. Complications were minor and rare (p >0.05). ConclusionAs we are aware of that, our study is the first in literature in which scopy is used in endoscopic DCR. In our study, the sEDCR approach is assessed as a useful modification which improves success and facilitates surgery.
