BACKGROUND: COVID-19 has had a significant effect on all aspects of life and occupational performance most recently. OBJECTIVE: This aim of this article was to discuss the concept of interference and the role that interference plays in productivity and potential across healthcare settings. METHODS: The framework design was the application of Bolea and Atwater’s interference framework to probe the COVID-19 pandemic within healthcare organizations. RESULTS: Leadership that focuses on transparency, frequent metric measurement can increase potential and then managing for unintended consequences can foster optimal occupational performance for both the practitioner and client. CONCLUSION: Interference is a critical concept in understanding organizational behavior. Transparent leadership is needed to adequately support organizations to create resilience in the workplace.

EFFECTS OF TECAR THERAPY ASSOCIATED WITH MANUAL THERAPY ON GLUTEAL SKIN FLACCIDITY

Background: A new technology called Tecar therapy, widely used in the orthopaedic area, has been studied in aesthetics in order to treat skin flaccidity. The equipment allows the association of radiofrequency with manual therapy. This study is an experimental research that aims to analyse the effects of the Tecar therapy associated with manual therapy on skin flaccidity of the gluteal region. Methods:Volunteers were individuals aged between 21 and 54, who presented skin flaccidity in the gluteal region. The sessions/applicationsoccurred once a week, totalling four applications with the TR THERAPY ELITE-6000 BTLTMdevice pre-set underthe following parameters: 500 KHz frequency, 100% duty cycle and 80% power, capacitive mode, in an area corresponding to twelve quarters measuring 7 cm² each, during60 minutes. Results:The evaluations were carried out in all the sessionsand included metric verification, photographic recording with subsequent photo submission to the AutoCAD software, and photogrammetric analysis. At the end of treatment, the volunteers answered anadaptedquestionnaire of satisfaction and a global aesthetic improvement scale form (GAIS). The results regarding AutoCAD, metric measurement, and photogrammetry did not present significant statistical differences. Conclusion:Although the statistical results were not satisfactorydespite its limitations regarding sample size,and possiblydue to the subjective analysis of the resources used as the evaluation methods. Still, the volunteers reported improvement in the texture and firmness of the skin in the treated region, indicating their satisfaction with the performed treatment.

French Adaptation of the Coparenting Relationship Scale

The Coparenting Relationship Scale (CRS) is a 35-item parent-reported questionnaire designed to assess the quality of the coparental relationship. It was designed in the United States and validated in English. We present in this article a French adaptation of the CRS. A total of 399 participants from the French-speaking part of Switzerland (146 fathers, 253 mothers) completed the questionnaire. Confirmatory factor analysis showed that the theoretically grounded seven-factor structure of the original instrument was valid to explain the structure of the Swiss data. Metric measurement invariance was achieved when comparing mothers and fathers, but only configural invariance was achieved when comparing the original US sample and the Swiss sample. Intercultural differences may possibly explain this result. Convergent validity was tested against parent-reported task sharing and health-related issues in children. Results of multiple hierarchical regression analyses showed theoretically coherent links between the dimensions of the French version and these variables. The French version of the CRS is thus a valid instrument to assess the coparental relationship.

Failure to Detect Metric Measurement Non-Invariance: How Manifest Residual Variances, Indicator Communalities, and Sample Size affect the χ2-Test Statistic

We investigate the effects of manifest residual variances, indicator communalities, and sample size on the χ2-test statistic of the metric measurement invariance model when the model is misspecified, i.e., there is at least one population loading that violates metric measurement invariance. First, we demonstrate the choice of the scaling method does not affect the model’s χ2-test statistic. Afterward, we demonstrate that the χ2-test statistic relates inversely to manifest residual variances, whereas sample size and χ2-test statistic show a positive relation. Moreover, we consider indicator communality as a key factor for the size of the χ2-test statistic. In this context, we introduce the concept of signal-to-noise ratio as a tool for studying the effects of manifest residual variance and indicator communality and demonstrate its use with the example. Finally, we discuss the limitations and the practical implications for the analysis of metric measurement invariance models.

An English-language adaptation of the Interpersonal Trust Short Scale (KUSIV3)

The Interpersonal Trust Short Scale—the English-language adaptation of the Kurzskala Interpersonelles Vertrauen (KUSIV3)—measures interpersonal trust as a psychological disposition with just three items (completion time ~ 30 s). The items of the German-language source version were translated into English using the TRAPD approach. Our empirical validation based on a heterogeneous quota sample in the UK shows that all the reliability coefficients of the English-language adaptation and its correlations with external variables are satisfactory and comparable to those of the German-language source version. Moreover, the results of measurement invariance testing suggest that metric measurement invariance of the scale holds when comparing the UK and Germany, implying the comparability of correlations based on the latent factors across the two nations. As an ultra-short scale, KUSIV3 lends itself to the assessment of interpersonal trust particularly in survey contexts in which assessment time or questionnaire space are limited. It is applicable in a variety of research disciplines, including psychology, sociology, and economics.

Analytical Study of Hybrid Techniques for Image Encryption and Decryption

The majority of imaging techniques use symmetric and asymmetric cryptography algorithms to encrypt digital media. Most of the research works contributed in the literature focus primarily on the Advanced Encryption Standard (AES) algorithm for encryption and decryption. This paper propose an analysis for performing image encryption and decryption by hybridization of Elliptic Curve Cryptography (ECC) with Hill Cipher (HC), ECC with Advanced Encryption Standard (AES) and ElGamal with Double Playfair Cipher (DPC). This analysis is based on the following parameters: (i) Encryption and decryption time, (ii) entropy of encrypted image, (iii) loss in intensity of the decrypted image, (iv) Peak Signal to Noise Ratio (PSNR), (v) Number of Pixels Change Rate (NPCR), and (vi) Unified Average Changing Intensity (UACI). The hybrid process involves the speed and ease of implementation from symmetric algorithms, as well as improved security from asymmetric algorithms. ECC and ElGamal cryptosystems provide asymmetric key cryptography, while HC, AES, and DPC are symmetric key algorithms. ECC with AES are perfect for remote or private communications with smaller image sizes based on the amount of time needed for encryption and decryption. The metric measurement with test cases finds that ECC and HC have a good overall solution for image encryption.

Morphometric Measurements of Cranio-Vertebral Junction among Nepalese Population

The craniovertebral junction area refers to the osseous structures consisting of the occipital bone that surrounds the foramen magnum, the atlas, and the axis vertebrae. There is sparse literature about the morph metric measurement of craniovertebral junction region. We aim to derive a range of various measurements incraniovertebral junction area. This is a hospital based single center retrospective study conducted in our center among 100 consecutive computed tomography scans of craniovertebral junction obtained in adult patients who were admitted to our tertiary hospital for treatment of non-craniovertebraljunction conditions between 2017 and 2018.Various craniovertebral junction morphology parameters were measured and confidence interval at 95% were obtained the range at 2standard deviation. Among 100 patients studied, 51% of them were males while 49% were females. Mean age was 35.1±10.4 years with range from 15 to50 years. Computed tomography measurement of craniovertebral junction revealed meanders height of 30.8±2.5 mms, dento-clivaldistance was 5.9±1.6 mms and mean McRae’s distance of 34.2±2.49 mms. Similarly, anterioratlantodental interval was calculated to be1.83±0.47 mms and posterior atlantodentalinterval was 17.72±0.21 mms while Modified RW distance was 24.43±2.09 mms and Redlund Johnell distance was calculated to be 31.5±4.29mms. Normal morphometric measurements ofcraniovertebral junction can be useful for evaluating abnormalities of the craniovertebraljunction which can potentially improve the diagnostic criteria of most abnormalities.

The Effects of Manifest Residual Variances, Indicator Communality, and Sample Size on the χ2-Test Statistic of the Metric Invariance Model

In this contribution, we investigate the effects of manifest residual variance, indicator communality and sample size on the χ2-test statistic of the metric measurement invariance model, i.e. the model with equality constraints on all loadings. We demonstrate by means of Monte Carlo studies that the χ2-test statistic relates inversely to manifest residual variance, whereas sample size and χ2-test statistic show the well-known pro- portional relation. Moreover, we consider indicator communality as a key factor for the size of the χ2-test statistic. In this context, we introduce the concept of signal-to-noise ratio as a tool for studying the effects of manifest residual error and indicator commu- nality and demonstrate its use with some examples. Finally, we discuss the limitations of this contribution and its practical implication for the analysis of metric measurement invariance models.
