Abstract:
Arabic language learning that is not optimal in class VII B at MTs Negeri 1 Sidoarjo is caused by the learning media used so far that is less attractive, and the teacher needs to include the four skills that the teacher into the learning media must own. So it is necessary to develop a learning media to help optimize learning. This study aims to explain and examine the learning media developed in the form of an android application called Lughotuna. The mixed method was used in this study. Data is sourced from informants who know the focus, such as school principals and learning admins obtained by observation and interviews. The supporting data comes from various books, journals and other encyclopedias. The data were then analyzed quantitatively and qualitatively. Learning media development includes 1) problem identification; 2) product design; 3) validation; and 4) product publication. In product design, there are two validations: media design validation and media content validation. Media design validation uses four aspects of assessment, including 1) ease of use and navigation; 2) aesthetics or beauty; 3) media integration, and 4) technical quality. In validating media content, three aspects of assessment are used, namely 1) suitability; 2) quality and purpose of content; and 3) instructional quality. In validating media design and media content, possible results are obtained.

Abstract:
This study aims to validate the prophetic leadership scale by using a quantitative approach. 202 leaders were involved in this study. Data analysis technique that has been used for construct validation is factorial validation with confirmatory factor analysis (CFA), a convergent validation, discriminant validation, and social desirability bias with Pearson correlation. There are 4 instruments used in this study, namely the measuring instrument of prophetic leadership, the measuring instrument of authentic leadership as a convergent validator, the measuring instrument of religiosity as a discriminant validator, and the measuring tool of social desirability as a validator of social appropriateness bias. The prophetic leadership measurement tool measures the same construct as the authentic leadership measurement tool, and measures different constructs from the religiosity measurement tool, and the prophetic leadership measurement tool has a social appropriateness bias or the respondent's tendency to give answers in accordance with norms. The findings raise a prospect that social desirability bias’s influences fitness indices in a scale’s validation.

Abstract:
Fish ageing researchers have long recognised the importance of validating age-reading methodologies. The strongest age validations require the acquisition of ageing structures from fish of known-ages, or specimens whose ages are appropriate for bomb carbon validation. Often such specimens are extremely difficult or impossible to acquire so researchers have sought alternatives to validation. The alternative to age validation is age corroboration. Corroboration of a fish ageing method occurs when fish ages are found to be consistent with some ancillary information when comparisons are made in an unbiased manner. The question pursued in this study is how desirable are such comparisons from a scientific viewpoint. Information is presented that corroborates otolith ages for walleye pollock (Theragra chalcogramma), one of the largest groundfish fisheries in the world. Walleye pollock ages were corroborated using marginal increment analysis, ages following the strong 1978 year class in the eastern Bering Sea, and a comparison of ages read from otoliths with ages read from vertebrae. A new statistical method is suggested for comparing otolith and vertebra age readings. The walleye pollock example demonstrated that corroborating evidence can improve confidence in fish ages and ageing techniques.

Abstract:
Background/ObjectiveGlobal navigation satellite systems (GNSS) and local positioning systems (LPS) are to date common tools to measure external training load in athletes. The aim of this scoping review was to map out and critically appraise the methods used to validate different GNSS and LPS used in team sports.MethodA total of 48 studies met the eligibility criteria and were included in the review. The reference systems applied in the validations, and the parameters investigated were extracted from the studies.ResultsThe results show a substantial range of reference systems used to validate GNSS and LPS and a substantial number of investigated parameters. The majority of the validation studies have employed relatively simple field-based research designs, with use of measure tape/known distance as reference measure for distance. Timing gates and radar guns were frequently used as reference system for average and peak speed. Fewer studies have used reference system that allow for validation of instantaneous dynamic position, such as infrared camera-based motion capture systems.ConclusionsBecause most validation studies use simple and cost-effective reference systems which do not allow to quantify the exact path athletes travel and hence misjudge the true path length and speed, caution should be taken when interpreting the results of validation studies, especially when comparing results between studies. Studies validating instantaneous dynamic position-based measures is warranted, since they may have a wider application and enable comparisons both between studies and over time.

Abstract:
OBJECTIVE: To identify nursing diagnoses (ND) currently appearing in the NANDA-I taxonomy, validated in the area of cardiology in Brazil. METHODS: An integrative literature review, guided by the following question: what nursing diagnoses were validated in Brazil? Eleven works were analyzed: three content validations and eight clinical validations. RESULTS: The NDs validated were: activity intolerance, decreased cardiac output, spiritual distress, deficient knowledge, excessive fluid volume, ineffective airway clearance, ineffective peripheral tissue perfusion, fear, anxiety, and pain. The highlights were the production of the graduate programs in public institutions, the validation of defining characteristics, models of validation and the modified Fehring criteria for selection of experts . The clinical validation model was used for NDs of the psychobiological sphere; the content validation model was used mainly for NDs in the psychosocial and psychospiritual spheres. CONCLUSION: The knowledge produced can provide a basis for future studies on the relevance of the content of nursing outcomes in the evaluation of the effectiveness of nursing interventions in the country.

Abstract:
The regional and global scale of aerosols in the atmosphere can be quantified using the aerosol optical depth (AOD) retrieved from satellite observations. To obtain reliable satellite AODs, conducting consistent validations and refining retrieval algorithms are crucial. AODs and Ångström exponents (AEs) measured with the aerosol robotic network (AERONET) are considered as the ground truth for satellite validations. AERONET AEs are used to collocate the wavelength of the AERONET AODs to those of the satellite AODs when there is a discordancy in their wavelengths. However, numerous validation studies have proposed different strategies by applying the AERONET AODs and AEs, and spatiotemporal collocation criteria. This study examined the impact of the wavelength and spatial collocation radius variations by comparing AODs at 550 nm derived from the geostationary ocean color imager (GOCI) with those obtained from the AERONET for the year 2016. The estimated AERONET AODs at 550 nm varied from 5.18% to 11.73% depending on the selection of AOD and AE, and the spatial collocation radii from 0 to 40 km, respectively. The longer the collocation radius and the higher the AODs, the greater the variability observed in the validation results. Overall, the selection of the spatial collocation radius had a stronger impact on the variability in the validation results obtained compared to the selection of the wavelength. The variability was also found in seasonal analysis. Therefore, it is recommended to carefully select the data wavelength and spatial collocation radius, consider seasonal effects, and provide this information when validating satellite AODs using AERONET.

Abstract:
Validating and theorizing are understood as parts of a common intellectual practice – theory creation – to know why reality is, or is changing, the way it is. This essay’s goal is to encourage debate about the role of validation in anthropological practice, with the aim of increasing that role. Argument is presented in Socratic fashion by posing, and responding to, questions. The first question inquires: What is validation? The second asks: Is getting the facts important in validation? The third queries: How do you get the facts? The fourth probes: What about objectivity in a biased world? The fifth demands: Why are intersubjectivity and representativeness important? Finally, the sixth section asks: If you do validate, can you get to the truth of something? It is concluded that skilled validation creates approximate truth, which is as close to knowing what is that people get.

Abstract:
AbstractSystematic approaches to validation of linear programming models are discussed for prescriptive and predictive applications to economic problems. Specific references are made to a general linear programming formulation, however, the approaches are applicable to mathematical programming applications in general. Detailed procedures are outlined for validating various aspects of model performance given complete or partial sets of observed, real world values of variables. Alternative evaluation criteria are presented along with procedures for correcting validation problems.

Abstract:
Objective: To conduct a systematic review, critical appraisal, and external validation of survival prediction tools for patients undergoing intrahepatic cholangiocarcinoma (iCCA) resection. Summary background data: Despite the development of several survival prediction tools in recent years for patients undergoing iCCA resections, there is a lack of critical appraisal and external validation of these models. Methods: We conducted a systematic review and critical appraisal of survival and recurrence prediction models for patients undergoing curative-intent iCCA resections. Studies were evaluated based on their model design, risk of bias, reporting, performance, and validation results. We identified the best model and externally validated it using our institution’s data. Results: This review included a total of 31 studies, consisting of 26 studies with original prediction tools and 5 studies that only conducted external validations. Among the 26, 54% of the studies conducted internal validations, 46% conducted external validations, and only 1 study scored a low risk of bias. Harrell’s C-statistics ranged from 0.67 to 0.76 for internal validation and from 0.64 to 0.75 for external validation. Only 81% of the studies reported model calibration. Our external validation of the best model (Intrahepatic Cholangiocarcinoma [ICC]-Metroticket) estimated Harrell’s and Uno’s C-statistics of 0.67 (95% CI: 0.56–0.77) and Uno’s time-dependent area under the receiver operating characteristic curve (AUC) of 0.71 (95% CI: 0.53–0.88), with a Brier score of 0.20 (95% CI: 0.15–0.26) and good calibration plots. Conclusions: Many prediction models have been published in recent years, but their quality remains poor, and minimal methodological quality improvement has been observed. The ICC-Metroticket was selected as the best model (Uno’s time-dependent AUC of 0.71) for 5-year overall survival prediction in patients undergoing curative-intent iCCA resection.

Abstract:
End-to-End Translation Validation is the problem of verifying the executable code generated by a compiler against the corresponding input source code for a single compilation. This becomes particularly hard in the presence of dynamically-allocated local memory where addresses of local memory may be observed by the program. In the context of validating the translation of a C procedure to executable code, a validator needs to tackle constant-length local arrays, address-taken local variables, address-taken formal parameters, variable-length local arrays, procedure-call arguments (including variadic arguments), and the alloca () operator. We provide an execution model, a definition of refinement, and an algorithm to soundly convert a refinement check into first-order logic queries that an off-the-shelf SMT solver can handle efficiently. In our experiments, we perform blackbox translation validation of C procedures (with up to 100+ SLOC), involving these local memory allocation constructs, against their corresponding assembly implementations (with up to 200+ instructions) generated by an optimizing compiler with complex loop and vectorizing transformations.

Abstract:
Allopurinol USP batches of same size, method, equipment and validation criterion were taken. The critical process parameter involved were reaction, drying, milling, sifting, milling, and blending stages were validation. Quality cannot be assured by daily quality control testing because of the limitations of statistical samples, and the limited facilities of finished product testing. Validation checks the accuracy and reliability of process. Aim of this work was to study prospective process validation of allopurinol USP designed to meet the current regulatory requirements and prove with assurance that the product meets the predetermined specifications and quality attributes. The critical process parameter was identified with the help of process capability and evaluated by challenging its in house and compendial specification. Three initial process validations batches APL/008, APL/009 and APL/010 were identified and evaluated as per validation master plan. The outcome indicated that this process validation data provides high degree of assurance so that manufacturing process produces a quality product.

Abstract:
A key prerequisite for the successful adoption of the Shapes Constraint Language (SHACL)---the W3C standardized constraint language for RDF graphs---is the availability of automated tools that efficiently validate targeted constraints (known as shapes graphs ) over possibly very large RDF graphs. There are already significant efforts to produce optimized engines for SHACL validation, but they focus on restricted fragments of SHACL. For unrestricted SHACL, that is SHACL with unrestricted recursion and negation, there is no validator beyond a proof-of-concept prototype, and existing techniques are inherently incompatible with the goal-driven approaches being pursued by existing validators. Instead they require a global computation on the entire data graph that is not only computationally very costly, but also brittle, and can easily result in validation failures due to conflicts that are irrelevant to the validation targets. To address these challenges, we present a 'magic' transformation---based on Magic Sets as known from Logic Programming---that transforms a SHACL shapes graph S into a new shapes graph S' whose validation considers only the relevant neighbourhood of the targeted nodes. The new S' is equivalent to S whenever there are no conflicts between the constraints and the data, and in case the validation of S fails due to conflicts that are irrelevant to the target, S' may still admit a lazy, target-oriented validation. We implement the algorithm and run preliminary experiments, showing our approach can be a stepping stone towards validators for full SHACL, and that it can significantly improve the performance of the only prototype validator that currently supports full recursion and negation.

Abstract:
. Cluster validation is a procedure to evaluate the results of cluster analysis quantitatively and objectively on a data. The validation process is very important to get the results of a good and appropriate grouping. In the validation process, the author uses internal validation, stability, and discriminant analysis test. This study aims to obtain validation results from the hierarchy and kmeans method. This data grouping uses “iris” simulation data, which results from the grouping method used can be applied to the original data to see which validation method is used for all data and produce an optimal grouping. The result of the study show that in the “iris” data, a single linkage link is an appropriate grouping method because the result of the grouping are optimal for all validations and classification of group members whose groups are significant. In Sub-district poverty data in Jember district with a single linkage link optimal grouping was obtained and complete linkage links were also used as a method that resulted in optimal grouping for all validation. Cluster validation using discriminant analysis test is appropriate for various types of data in general and shows that single linkage methods are better than other methods for grouping and validation methods for “iris” data and Sub-district data in Jember district based on variables of poverty status.

Abstract:
AbstractBackground:Therapist validation in treatment is theorized to be related to positive outcomes (Linehan, 1993), including keeping patients in therapy longer.Aims:We sought to evaluate the role of therapist validation from both therapists’ and clients’ perspectives as a predictor of drop-out from psychotherapy in three cognitive behavioural training clinics.Method:Clients in psychotherapy (n = 50; 80% female; 82% Caucasian) and their trainee therapists (n = 22; 68% female; 86% Caucasian) rated validation by the therapist at each of four early sessions of therapy.Results:After accounting for symptom severity, clients who reported greater therapist validation were less likely to drop out of treatment. Therapist ratings of their own validating behaviours were unrelated to client drop-out. Therapist experience moderated the relation between client-rated validation and drop-out, such that validation was unrelated to drop-out for more experienced therapists.Conclusions:Assessing and attending to client perceptions of validation by the therapist early in treatment, with brief self-report inventories, can alert therapists to clients at greater risk of drop-out.

Abstract:
Interest in systematic approaches to improving clinical empathy has increased. However, conceptualizations of empathy are inconsistent and difficult to operationalize. Drawing on video recordings of primary care visits with older adults, I describe one particular communication strategy for conveying empathy—empathic validation. Using conversation analysis, I show that the design of empathic validations and the context in which they are delivered are critical to positive patient responses. Effective empathic validations must (a) demonstrate shared understanding and (b) support the patient’s position. Physicians provided empathic validation when there was no medical solution to offer and within this context, for three purposes: (1) normalizing changes in health, (2) acknowledging individual difficulty, and (3) recognizing actions or choices. Empathic validation is a useful approach because it does not rely on patients’ ability to create an “empathic opportunity” and has particular relevance for older adults.

Abstract:
AbstractBackground and aimsChronic pain not only affects the person in pain, but can also have a negative impact on relationships with loved ones. Research shows that chronic pain is associated with difficulties in marital relationships, which in turn is related to a variety of negative outcomes such as psychological distress and conflict within the family. This suggests that couples where chronic physical pain is present also struggle with emotional pain and relationship problems, and thus targeting relationship skills and interpersonal functioning might be helpful for these couples. Although studies in this area are promising, their numbers are few. In the present study, validation as a way of communicating is suggested for handling emotional expression in interpersonal interactions. Validation communicates understanding and acceptance of the other person’s experience, and it has been shown to have a down-regulating effect on negative emotions. It has previously been demonstrated to be important for these couples. However, the feasibility and effects of increasing partner validation in these couples are unknown. Therefore, the aim of the present study was to investigate if a brief training session in validation for spouses would result in more validating and fewer invalidating responses towards their partners with pain, and to investigate if changes in these behavioural responses were associated with changes in emotion and pain level in the partner with pain.MethodsParticipants were 20 couples where at least one partner reported chronic pain. The study employed a within-groups design in which spouses of people with pain received validation training (without their partner’s knowledge), and their validating and invalidating responses were rated pre- and post-intervention using a reliable observational scale. Also, positive and negative affect and subjective pain level in the persons with pain were rated pre- and post-intervention.ResultsResults showed that the validation training was associated with increased validating and decreased invalidating responses in the partners. Their spouses with chronic pain reported a decrease in negative affect from pre- to post-training.ConclusionsOur results indicate that the partner or closest family member, after brief validation training, increased validating responses and decreased invalidating responses towards the person with pain, which had an immediate positive impact on emotions in the other person.ImplicationsThis study suggests that using validation in interpersonal interactions is a promising tool for couples where chronic pain is present.

Abstract The AAMI working group ST/WG 93 is finalizing a standard (AAMI ST98) for the cleaning validation of reusable medical devices based on guidance from the technical information report AAMI TIR30:2011/(R)2016. A number of analytical best practices are being considered for this new standard. Test method suitability for processing cleaning validations historically has been established using one positive control and performing an extraction efficiency. The new cleaning validation standard is proposed to require a change from only one replicate test sample to three when performing method suitability. This change will affect manufacturers; therefore, the value of and consideration for performing these additional replicates requires explanation. This article discusses how variation of validation parameters can affect the accuracy and precision during method suitability testing. Multiple replicates are needed to understand the variability of method extraction and impact on cleaning validations of reusable medical devices.
