The school is an institution that represents an important link in the social care chain for children and young people, which also involves taking various measures to prevent the occurrence of undesirable behaviors. The aim of the study is to determine the prevalence of risk factors between adolescents with externalized and internalized problems and typically developing adolescents, and to determine in which segment, in the opinion of teachers, early social-pedagogical intervention is most needed. The research sample is made up of 450 students (233 male and 217 female) of the seventh and eighth grades of primary school. The results show that the highest risk factors are present in the group of students with externalized behavioral problems, slightly less in the group with internalized problems, and the least in students without behavioral and emotional problems. When it comes to early social-pedagogical interventions, in the opinion of teachers, they should be comprehensive and implemented by a competent expert.

Serious, systematic and massive violations of international humanitarian law were committed during the 1992-1995 armed conflict in the territory of Bosnia and Herzegovina. The criminal prosecution and prosecution of perpetrators of these violations of international humanitarian law falls within the jurisdiction of several courts of various levels, namely the ICTY, the courts in Bosnia and Herzegovina, as well as the courts of other countries, in accordance with the principle of universal jurisdiction. However, the fact that is justifiably worrying is that, even after 24 years since the end of the war, the work on prosecuting those responsible for violations of international humanitarian law in Bosnia and Herzegovina is nowhere near completion. This is a consequence of non-compliance with the guidelines of the National War Crimes Processing Strategy, implementation of various laws at the state and entity levels, as well as limited regional cooperation and dialogue. The results of the research show that the concerns and perceptions expressed by citizens, as well as by some domestic and international institutions regarding the effectiveness of prosecutors' offices in prosecuting war crimes cases are very justified. Such data call for action by all relevant individuals and institutions to undertake activities in their own domain in order to advance this process and bring it to the level it deserves, given the importance for the overall BiH society.

After the defeat of Hungary by the Ottoman Empire, in August of 1415, the Bosnian king and a few noble men made a decision to change their political loyalty towards the Hungary. King Ostoja tried to take care of inside matters that were ruling in Bosnian Kingdom. He called for a meeting (Stanak) at which he would even out with some noble men. Even Dubrovcani wrote about this event. In one of their letters they described the events that took place in Kraljeva Sutjeska. After the occurrence in Kraljeva Sutjeska, intervention of Ottoman army was expected. One of the facts that the situation was pretty serious is that some families sought asylum from Dubrovnik’s authorities in case of alarming circumstances. One of Bosnian powerful nobles dies in 1416. King Ostoja and other noblemen were fighting over his property.

Authors: ARABACI Gülperi
Published: August 2021

Giriş: Bu çalışmada, dördüncü sınıfa devam eden 55 öğrencinin (27’si öğrenme güçlüğü olan ve 28’i tipik gelişim gösteren) akıcı okuma ve okuduğunu anlama becerilerindeki performansları ve her iki beceri arasındaki ilişki düzeyinin belirlenmesi amacıyla karşılaştırmalı olarak incelenmesi amaçlanmıştır.Yöntem: Çalışmada nicel araştırma yöntemlerinden ilişkisel tarama modeli kullanılmıştır. Katılımcıların akıcı okuma (doğru okuma, hız ve prozodi) ve okuduğunu anlama becerileri dördüncü sınıf düzeyinde geçerliği ve güvenirliği sağlanmış iki metin ve çoktan seçmeli test soruları ile veri toplanarak incelenmiştir. Araştırma verilerinin analizi SPSS 18.00 istatistik programı ile yapılmıştır.Bulgular: Çalışmadan elde edilen bulgulara göre; öğrenme güçlüğü olan öğrencilerin akıcı okuma ve okuduğunu anlama becerilerinde tipik gelişim gösteren öğrencilere göre anlamlı şekilde daha düşük puan aldıklarını göstermiştir. Akıcılık ve okuduğunu anlama arasındaki ilişkiler incelendiğinde öğrenme güçlüğü olan öğrencilerde okuma hızı ile okuduğunu anlama arasında, tipik gelişim gösteren öğrencilerde ise prozodi ile okuduğunu anlama arasında pozitif yönlü orta düzeyde anlamlı bir ilişki olduğu görülmüştür.Tartışma: Bu araştırmada, öğrenme güçlüğü olan öğrencilerin hem akıcı okuma hem de okuduğunu anlamada akranlarının önemli ölçüde gerisinde oldukları ve bu becerilerinin geliştirilmesi gerektiği belirlenmiştir. Tipik gelişim gösteren akranlarının okuma becerilerinde önemli derecede ilerlediği ve öğretimin diğer akademik alanlardaki öğrenmeye daha çok odaklandığı dördüncü sınıfta yaşadıkları bu okuma problemlerinin daha sonraki yıllarda yaşanacak akademik başarısızlıklara neden olacağı kaçınılmazdır.

PAULO FREIRE E A GESTÃO DEMOCRÁTICA COMO POLÍTICA EDUCACIONAL: OPOSIÇÕES AO NEOLIBERALISMO
Authors: Costa Daianny Madalena , Paulo Fernanda
Published: August 2021

O conceito de gestão democrática em Paulo Freire ancora-se num projeto popular, político e pedagógico. O artigo, por isso, analisa sua relação com a política educacional e as tensões neoliberais, a qual, perversamente demarca o arrefecimento à democracia. Por meio da pesquisa bibliográfica e uma análise hermenêutico-dialética, aponta-se para a necessidade de radicalizar a democracia, reinventando-a e desconstruindo o discurso e práticas autoritárias, presentes no projeto de educação neoliberal e mercadológica. É necessário, portanto, avançar em torno da compreensão sobre a participação popular dialógica.

Published: August 2021

Antiviral drugs are a class of medications used for treating viral infections. Due to their widespread use, especially in cases of pandemics and limited human metabolism, antivirals have been detected in multiple environmental matrices. This study aims to evaluate the chronic effects of acyclovir, efavirenz, lamivudine and zidovudine using Ceriodaphnia dubia and Raphidocelis subcapitata. The results with R. subcapitata showed the following toxicities: zidovudine (IC50 = 5.442 mg L−1) < acyclovir (IC50 = 3.612 mg L−1) < lamivudine (IC50 = 3.013 mg L−1) < efavirenz (IC50 = 0.034 mg L−1). The results of the chronic bioassay with C. dubia demonstrated that zidovudine is the least toxic (EC50 = 5.671 mg L−1), followed by acyclovir (EC50 = 3.062 mg L−1), lamivudine (EC50 = 1.345 mg L−1) and efavirenz (EC50 = 0.026 mg L−1). Both species have been shown to be sensitive to efavirenz. A risk quotient (RQ) was calculated, and efavirenz had an RQ greater than 1 for both species, and lamivudine had an RQ greater than 1 for C. dubia, representing a high ecological risk for these organisms. Antivirals pose a significant environmental risk to aquatic organisms and should be taken into consideration in future monitoring of water sources.

Published: August 2021

A constructed wetland (CW) is a low-cost, eco-friendly, easy-to-maintain, and widely applicable technology for treating various pollutants in the waste landfill leachate. This study determined the effects of the selection and compiling strategy of substrates used in CWs on the treatment performance of a synthetic leachate containing bisphenol A (BPA) as a representative recalcitrant pollutant. We operated five types of lab-scale vertical-flow CWs using only gravel (CW1), a sandwich of gravel with activated carbon (CW2) or brick crumbs (CW3), and two-stage hybrid CWs using gravel in one column and activated carbon (CW4) or brick crumbs (CW5) in another to treat synthetic leachate containing BPA in a 7-d sequential batch mode for 5 weeks. CWs using activated carbon (CW2 and CW4) effectively removed ammonium nitrogen (NH4-N) (99–100%), chemical oxygen demand (COD) (93–100%), and BPA (100%), indicating that the high adsorption capacity of activated carbon was the main mechanism involved in their removal. CW5 also exhibited higher pollutant removal efficiencies (NH4-N: 94–99%, COD: 89–98%, BPA: 89–100%) than single-column CWs (CW1 and CW3) (NH4-N: 76–100%, COD: 84–100%, BPA: 51–100%). This indicates the importance of the compiling strategy along with the selection of an appropriate substrate to improve the pollutant removal capability of CWs.
Parathyroid Hormone-regulation of Runx2 by MiR-290 for Matrix
Metalloproteinase-13 Expression in Rat Osteoblastic Cells
Authors: Akshaya N. , Srinaath N. , Rohini M. , Ilangovan R. , Selvamurugan N.
Published: August 2021

Background:

The dynamic changes that bone undergoes during the
ensemble of remodeling are administered by vital factors like Runx2 (a bone
transcription factor) and matrix metalloproteinases (MMPs).

Aims:

Parathyroid hormone (PTH), an FDA approved drug for bone-related ailments,
was seen to stimulate MMP-13 expression via Runx2 to ultimately aid in the bone
remodeling process. MicroRNAs (miRNAs) have been shown to play a major role in
controlling bone metabolism, and the use of miRNAs has recently become promising
therapeutic avenues for the treatment of many diseases, including bone disorders. Thus,
in this study, we attempted to investigate and evaluate the expression of MMP-13 via a
miRNA profile targeting Runx2 under PTH-regulation in rat osteoblastic cells.

Methods:

PTH stimulated the expression of MMP-13 mRNA significantly at 4 h in rat
osteoblastic cells (UMR106-01). Runx2 was required for PTH-stimulation of MMP-13
expression, in silico scrutiny generated 14 unique miRNAs targeting Runx2, and among
these miRNAs, miR-290 was significantly downregulated by PTH-treatment in UMR106-
01 cells and in rat primary osteoblasts.

Results:

Overexpression of miR-290 decreased the expression of Runx2, the binding of
Runx2 at the MMP-13 promoter, and the expression of MMP-13 mRNA in PTH-treated
UMR106-01 cells. A dual luciferase reporter assay identified the direct targeting of
Runx2 mRNA by miR-290 in these cells.

Conclusion:

Our findings indicate that the PTH-responsive miR-290 regulated Runx2-
mediated MMP-13 expression in rat osteoblastic cells, suggesting miR-290 as a
molecular marker or target in bone and bone-related diseases.
Numerical Simulation and Experimental Research of Oil-free Scroll Air
Compressor Based on CFD
Authors: Jian Sun , Bin Peng , Bingguo Zhu
Published: August 2021

Background:

Compared with other types of compressors, although the scroll compressor has
a simple structure and low noise, due to the limitation of the structure, it has defects such as excessively
high discharge temperature, and has extremely high requirements on the machining accuracy of parts.
The oil-free scroll compressor is a new type of scroll machine, which does not contain oil during the
working process; it can be applied to cases with low displacement requirements and a high-pressure ratio.

Objective:

Taking a scroll compressor with a rated displacement of 0.6 m3/min as the research object,
the analysis and research of the working performance parameters of the scroll compressor in actual
work provide a certain theoretical basis for the improvement and optimization of the test prototype.

Methods:

The thermodynamic model of the scroll compressor in the actual working process is established
by the variable-mass system thermodynamics and the control volume method. Based on the CFD
method, a three-dimensional unsteady-state numerical simulation of the flow characteristics of the
working fluid in the scroll compressor's working chamber is carried out in order to verify the thermodynamic
model. Considering the accuracy of numerical simulation, a test platform with air as the working
fluid is set up.

Results:

Through the thermodynamic model and numerical simulation, the changes of temperature,
pressure and velocity in the working chamber of the scroll compressor with the orbiting angle of the
main shaft as well as the gas force and torque acting on the orbiting scroll tooth are obtained. Through
experiments, the law of volume flow and shaft power of the scroll compressor with the speed of change,
and the law of the change of discharge temperature with pressure at different speeds are obtained.

Conclusion:

At the same time, the thermodynamic model established by considering heat transfer and
leakage is more in line with the actual working process of the compressor; the mass exchange between
adjacent working chambers of the scroll compressor has a greater impact on the temperature and pressure
in the working chamber. Due to internal leakage and irreversible loss, such as heat transmission,
there is a deviation between the theoretical volume flow and the actual volume flow.

PEMBATASAN TERHADAP PERSAINGAN UNTUK MEMBENTUK PASAR DALAM KASUS STANDARD ESSENTIAL PATENT (SEP) (PERBANDINGAN HUKUM PERSAINGAN USAHA DI INDONESIA DAN UNI EROPA)
Authors: Wahyuningtyas Sih
Published: August 2021

The role of patents is complex when dealing with the problem of technological interoperability in cases where patented technology becomes standard. In such cases, a balance is needed between the protection of the interests of the inventor, i.e. the standard essential patent (SEP) holder, and of users who need the technology to enter the market. There is a susceptibility to restrictions on competition to create markets (competition for the market). Market dominance can be created by the adoption of SEP holder technology as a standard and hence, a key for other business actors to enter the market. With the potential for the formation of a dominant position in the relevant market, the competition law intervention is required when patent abuse occurs, as it appears typical in the pharmaceutical and information technology industries. The normative research examines how competition law in the European Union deals with SEP cases in comparison to Indonesian competition law.

Cleaner production (CP) is one of the sustainable implementations of a comprehensive preventive environmental strategy involving company processes, products, and services. CP plan implementation still faces obstacles, such as the lack of detailed information, tools, and techniques. This study aimed to determine the variables and to select alternative solutions for cleaner production at a fruit chip industry using the Analytical Hierarchy Process (AHP) method. The research was carried out at PT Agrijaya Indotirta in Malang, East Java. The production process at this company generates waste from the consumption of energy, water, materials, and raw materials. Energy and water consumption are disposed directly without preliminary recycling process. Used oil is sold, and the remaining fruit seeds are sold for seeds. Checklists are used for problem identification, while fishbone diagrams and the 5W1H method are used to solve the problem of getting the best solution from the available alternatives. The weighting results of the alternative solutions using the AHP method show that the application of Good Manufacturing Practice (GMP) (with a weight of 0.287080) on the human resource criteria (with a weight of 0.63699) is a suitable alternative solution for the CP application of fruit chips production at PT Agrijaya Indotirta. Cleaner production can be performed by improving the capacity of human resources as production actors and regulators of proper waste management.

Face Recognition Use Local Image Dataset and Correlation Technique
Authors: Abd Dana Faiq
Published: August 2021

Face recognition is an extreme topic in security field which identifies humans through physiological or behavioral biometric characteristics. Face recognition can also identify the human almost in a precise detection; one of the primary problems in face recognition is the accurate recognition rate. Local datasets use for implementing this research rather than using public datasets. Midian filter uses to remove noise and identify errors, also obtains a good accuracy rate without modifying image quality. In addition, filter processing applies to modify and progress images and the discrete wavelet transforms algorithm uses as feature extraction. Many steps are applied in this approach such as image acquisition, converting images into gray scale, cropping the image, and then passing to the feature extraction. In order to get the final decision about the indicated face, some required steps are used in the comparison. The results show the accuracy of 91% of the recognition rate through the human face.
Exploring Mothers’ Experience of a Linguistic Feedback Technology for Children at Risk of Poor Language Development: Qualitative Pilot Study
Authors: So Lydia , Miller Erin , Eastwood John
Published: August 2021

Background

The early language environment is important for language development and a child’s life-course trajectory. Risk factors associated with poor language development outcomes in children include maternal anxiety and depression, low educational attainment, substance misuse, and low socioeconomic status. Language Environment Analysis (LENA) is a wearable technology designed to promote caregivers’ engagement in supporting their children’s language development. LENA provides quantitative linguistic feedback, which has been shown to improve caregiver language output, thus enhancing a child’s language environment. There is limited research on the uptake of this technology by families with developmentally at-risk children.

Objective

This qualitative study aims to explore the conditions under which mothers with children at risk of poor developmental outcomes are willing to adopt the use of LENA to monitor and improve caregiver language output.

Methods

Using a qualitative interpretive design, semistructured, in-depth interviews were conducted with 8 mothers. Participants were recruited purposively to select the maximal variation of socioeconomic and ethnodemographic backgrounds. The transcribed interview data were analyzed thematically and interpretatively. Themes were mapped abductively to an extended Unified Theory of Acceptance and Use of Technology, which included contextual factors for LENA acceptance.

Results

Factors that influenced the intention to use LENA included both technology-specific acceptance factors and contextual factors. Technology acceptance themes included reassurance, feeling overwhelmed, and trust. These themes were mapped to performance expectancy, effort expectancy, and social influence. Contextual themes included emergent success and the intrusion of past difficulties. These were mapped to parenting self-efficacy and perceived risk. The theme of building on success described behavioral intention. Mothers were more likely to adopt LENA when the technology was viewed as acceptable, and this was influenced by parenting self-efficacy and perceived risk.

Conclusions

LENA is a technology that is acceptable to mothers with children who are at risk of poor language development outcomes. Further studies are needed to establish LENA’s effectiveness as an adjunct to strategies to enrich a child’s early language environment.
Patterns of Missing Data With Ecological Momentary Assessment Among People Who Use Drugs: Feasibility Study Using Pilot Study Data
Authors: Markowski Kelly L , Smith Jeffrey A , Gauthier G Robin , Harcey Sela R
Published: August 2021

Background

Ecological momentary assessment (EMA) is a set of research methods that capture events, feelings, and behaviors as they unfold in their real-world setting. Capturing data in the moment reduces important sources of measurement error but also generates challenges for noncompliance (ie, missing data). To date, EMA research has only examined the overall rates of noncompliance.

Objective

In this study, we identify four types of noncompliance among people who use drugs and aim to examine the factors associated with the most common types.

Methods

Data were obtained from a recent pilot study of 28 Nebraskan people who use drugs who answered EMA questions for 2 weeks. We examined questions that were not answered because they were skipped, they expired, the phone was switched off, or the phone died after receiving them.

Results

We found that the phone being switched off and questions expiring comprised 93.34% (1739/1863 missing question-instances) of our missing data. Generalized structural equation model results show that participant-level factors, including age (relative risk ratio [RRR]=0.93; P=.005), gender (RRR=0.08; P=.006), homelessness (RRR=3.80; P=.04), personal device ownership (RRR=0.14; P=.008), and network size (RRR=0.57; P=.001), are important for predicting off missingness, whereas only question-level factors, including time of day (ie, morning compared with afternoon, RRR=0.55; P<.001) and day of week (ie, Tuesday-Saturday compared with Sunday, RRR=0.70, P=.02; RRR=0.64, P=.005; RRR=0.58, P=.001; RRR=0.55, P<.001; and RRR=0.66, P=.008, respectively) are important for predicting expired missingness. The week of study is important for both (ie, week 2 compared with week 1, RRR=1.21, P=.03, for off missingness and RRR=1.98, P<.001, for expired missingness).

Conclusions

We suggest a three-pronged strategy to preempt missing EMA data with high-risk populations: first, provide additional resources for participants likely to experience phone charging problems (eg, people experiencing homelessness); second, ask questions when participants are not likely to experience competing demands (eg, morning); and third, incentivize continued compliance as the study progresses. Attending to these issues can help researchers ensure maximal data quality.
An Artificial Neural Network–Based Pediatric Mortality Risk Score: Development and Performance Evaluation Using Data From a Large North American Registry (Preprint)

Published: August 2021

BACKGROUND

In the pediatric intensive care unit (PICU), quantifying illness severity can be guided by risk models to enable timely identification and appropriate intervention. Logistic regression models, including the pediatric index of mortality 2 (PIM-2) and pediatric risk of mortality III (PRISM-III), produce a mortality risk score using data that are routinely available at PICU admission. Artificial neural networks (ANNs) outperform regression models in some medical fields.

OBJECTIVE

In light of this potential, we aim to examine ANN performance, compared to that of logistic regression, for mortality risk estimation in the PICU.

METHODS

The analyzed data set included patients from North American PICUs whose discharge diagnostic codes indicated evidence of infection and included the data used for the PIM-2 and PRISM-III calculations and their corresponding scores. We stratified the data set into training and test sets, with approximately equal mortality rates, in an effort to replicate real-world data. Data preprocessing included imputing missing data through simple substitution and normalizing data into binary variables using PRISM-III thresholds. A 2-layer ANN model was built to predict pediatric mortality, along with a simple logistic regression model for comparison. Both models used the same features required by PIM-2 and PRISM-III. Alternative ANN models using single-layer or unnormalized data were also evaluated. Model performance was compared using the area under the receiver operating characteristic curve (AUROC) and the area under the precision recall curve (AUPRC) and their empirical 95% CIs.

RESULTS

Data from 102,945 patients (including 4068 deaths) were included in the analysis. The highest performing ANN (AUROC 0.871, 95% CI 0.862-0.880; AUPRC 0.372, 95% CI 0.345-0.396) that used normalized data performed better than PIM-2 (AUROC 0.805, 95% CI 0.801-0.816; AUPRC 0.234, 95% CI 0.213-0.255) and PRISM-III (AUROC 0.844, 95% CI 0.841-0.855; AUPRC 0.348, 95% CI 0.322-0.367). The performance of this ANN was also significantly better than that of the logistic regression model (AUROC 0.862, 95% CI 0.852-0.872; AUPRC 0.329, 95% CI 0.304-0.351). The performance of the ANN that used unnormalized data (AUROC 0.865, 95% CI 0.856-0.874) was slightly inferior to our highest performing ANN; the single-layer ANN architecture performed poorly and was not investigated further.

CONCLUSIONS

A simple ANN model performed slightly better than the benchmark PIM-2 and PRISM-III scores and a traditional logistic regression model trained on the same data set. The small performance gains achieved by this two-layer ANN model may not offer clinically significant improvement; however, further research with other or more sophisticated model designs and better imputation of missing data may be warranted.

Published: August 2021

BACKGROUND

Blended models of therapy, which incorporate elements of both internet and face-to-face methods, have been shown to be effective, but therapists and patients have expressed concerns that fewer face-to-face therapy sessions than self-guided internet sessions may be associated with lower therapeutic alliance, lower program completion rates, and poorer outcomes.

OBJECTIVE

A multisite quasi-experimental comparison study with a noninferiority design implemented in routine clinical care was used to assess webSTAIR, a 10-module blended therapy derived from STAIR (skills training in affective and interpersonal regulation) for trauma-exposed individuals delivered with 10 weekly therapist sessions (termed Coach10) compared to 5 biweekly sessions (Coach5). It was hypothesized that Coach5 would be as good as Coach10 in a range of outcomes.

METHODS

A total of 202 veterans were enrolled in the study with 101 assigned to Coach5 and 101 to Coach10. Posttraumatic stress disorder (PTSD) symptoms, depression, emotion regulation, interpersonal problems, and social functioning measures were collected pre-, mid-, and posttreatment, and at a 3-month follow-up. Noninferiority analyses were conducted on symptom outcome measures. Comparisons were made of continuous and categorical measures regarding participant and therapist activities.

RESULTS

Participants reported moderate to severe levels of baseline PTSD, depression, or both. Significant reductions were obtained in all symptom measures posttreatment and at the 3-month follow up. Coach5 was not inferior to Coach10 in any outcome. Therapeutic alliance was at an equivalently high level across the 2 treatment conditions; completion rates and web usage were similar. Total session time was substantially less for the Coach5 therapists than the Coach10 therapists. Both programs were associated with a low, but equal number of therapist activities related to scheduling and crisis or motivational sessions.

CONCLUSIONS

A blended model delivered with 5 sessions of therapist support was noninferior to 10 sessions in individuals with moderate to severe symptoms. Future studies identifying patient characteristics as moderators of outcomes with high versus low doses of therapist support will help create flexible, technology-based intervention programming.
An mHealth App to Support Caregivers in the Medical Management of Their Child With Cancer: Co-design and User Testing Study (Preprint)
Authors: Mueller Emily L , Cochrane Anneli R , Campbell Madison E , Nikkhah Sarah , Miller Andrew D
Published: August 2021

BACKGROUND

Caregivers face new challenges and tasks when their child is diagnosed with cancer, which can be overwhelming. Mobile technology has the capacity to provide immediate support at their fingertips to aid in tracking symptoms, managing medication, and planning for emergencies.

OBJECTIVE

The objective of this study is to engage directly with end users and proxies to co-design and create a mobile technology app to support caregivers in the medical management of their child with cancer.

METHODS

We engaged directly with caregivers of children with cancer and pediatric oncology nurse coordinators (proxy end users) to co-design and create the prototype of the Cope 360 mobile health app. Alpha testing was accomplished by walking the users through a series of predetermined tasks that encompassed all aspects of the app including tracking symptoms, managing medications, and planning or practicing for a medical emergency that required seeking care in the emergency department. Evaluation was accomplished through recorded semistructured interviews and quantitative surveys to capture demographic information and measure the system usability score. Interviews were transcribed and analyzed iteratively using NVivo (version 12; QSR International).

RESULTS

This study included 8 caregivers (aged 33-50 years) of children with cancer, with most children receiving chemotherapy, and 6 nurse coordinators, with 3 (50%) of them having 11 to 20 years of nursing experience. The mean system usability score given by caregivers was 89.4 (95% CI 80-98.8). Results were grouped by app function assessed with focus on specific attributes that were well received and those that required refinement. The major issues requiring refinement included clarity in the medical information and terminology, improvement in design of tasks, tracking of symptoms including adjusting the look and feel of certain buttons, and changing the visual graph used to monitor symptoms to include date anchors.

CONCLUSIONS

The Cope 360 app was well received by caregivers of children with cancer but requires further refinement for clarity and visual representation. After refinement, testing among caregivers in a real-world environment is needed to finalize the Cope 360 app before its implementation in a randomized controlled trial.

Published: August 2021

BACKGROUND

Background: Latent Dirichlet Allocation (LDA) is a tool for rapidly synthesising meaning from ‘big data’, but outputs can be sensitive to decisions made during the analytic pipeline. This review will focus on the complex analytical practices specific to LDA, which existing practical guides for conducting LDA have not addressed.

OBJECTIVE

Objectives: This scoping review will use key analytical steps (data selection, data pre-processing, and data analysis) as a framework to understand the methodological approaches being used in psychology research utilising LDA.

METHODS

Methods: Four psychology and health databases were searched. Studies were included if they used LDA to analyse written words and focussed on a psychological construct/issue. The data charting processes was constructed and employed based on common data selection, pre-processing, and data analysis steps.

RESULTS

Results: Forty-seven studies were included. These explored a range of research areas and most sourced their data from social media platforms. While some studies reported on pre-processing and data analytic steps taken, most studies did not provide sufficient detail for reproducibility. Furthermore, debate surrounding the necessity of certain pre-processing and data analysis steps is revealed.

CONCLUSIONS

Conclusions: Findings highlight the growing use of LDA in psychological science. However, there is a need to improve analytical reporting standards, and identify comprehensive and evidence based best practice recommendations. To work towards this, we have developed an LDA Preferred Reporting Checklist which will allow for consistent documentation of LDA analytic decisions, and reproducible research outcomes.
