Confirmation Bias in Simulated Child Sexual Abuse (CSA) Interviews: Abuse Assumption Influences Interviewing and Decision-making Processes

PurposeResearch has shown that confirmation bias plays a role in legal and forensic decision-making processes. However, to our knowledge, no study has examined how it manifests itself when interviewing an allegedly abused child. MethodIn the present study, we used data from a series of experiments in which participants interviewed child avatars to examine how an assumption of abuse based on preliminary information influenced decision-making and interviewing style. Interview training data from eight studies with students, psychologists and police officers were included in the analyses.ResultsWe found that interviewers’ preliminary assumption of sexual abuse having taken place predicted 1) a conclusion of abuse by the interviewers after the interview; 2) higher confidence in their judgment; 3) more frequent use of not recommended question types and 4) a decreased likelihood of reaching a correct conclusion given the same number of available relevant details. ConclusionThe importance of considering how preliminary assumptions of abuse affect interview behaviour and outcomes and the implications for the training of investigative interviewers were discussed.

Clinical and behavioral correlates in adult methamphetamine users with childhood exposure to household drug and alcohol use

Aims: To describe and compare methamphetamine (MA) users with and without a family history of alcohol or drug () use in the household. Design: A total of 1144 Thai-speaking MA users in Thailand were recruited for a cohort study. Cross-sectional baseline data were analyzed according to their exposure to FAOD use (FAOD+/FAOD-). The Semi-Structured Assessment for Drug Dependence and Alcoholism (SSADDA) was utilized to collect baseline socio-demographic information and variables known to be associated with the impact of FAOD use. Findings: FAOD+ participants had lower average years of education (p<0.01), fewer average months of employment in the past year (p<0.01) and reported higher rates of self-harm experience (p<0.001), gambling (p=0.018) and antisocial personality disorder (p=0.015). FAOD+ participants had more severe clinical, adverse consequences. FAOD+ significantly predicted episodes of lifetime MA use (R2 =0.004, p=0.032), the largest number of drinks ever had in a 24-hour period (R2 =0.01, p=0.001), paranoid experiences ([OR]=1.090, p=0.004), alcohol dependence ([OR]=1.112, p=0.001) and antisocial personality disorder ([OR]=1.139, p=0.015). FAOD+ participants who were exposed to alcohol only were more likely to report a significantly higher number of drinks ever had in a 24-hour periods (p<0.005). Similarly, FAOD+ participants who were exposed to MA use only were significantly more likely to report more frequent use of MA (p<0.005). Conclusions: FAOD+ participants were characterized by a generally more severe clinical presentation than FAOD- participants. Moreover, we show the specificity of drug type mattered, with family exposure of alcohol and MA associated with greater subsequent use of the respective drugs.

Survey on Reverse-Engineering Tools for Android Mobile Devices

With the presence of the Internet and the frequent use of mobile devices to send several transactions that involve personal and sensitive information, it becomes of great importance to consider the security aspects of mobile devices. And with the increasing use of mobile applications that are utilized for several purposes such as healthcare or banking, those applications have become an easy and attractive target for attackers who want to get access to mobile devices and obtain users’ sensitive information. Developing a secure application is very important; otherwise, attackers can easily exploit vulnerabilities in mobile applications which lead to serious security issues such as information leakage or injecting applications with malicious programs to access user data. In this paper, we survey the literature on application security on mobile devices, specifically mobile devices running on the Android platform, and exhibit security threats in the Android system. In addition, we study many reverse-engineering tools that are utilized to exploit vulnerabilities in applications. We demonstrate several reverse-engineering tools in terms of methodology, security holes that can be exploited, and how to use these tools to help in developing more secure applications.

The Love and Science of Reading: A Promising Instructional Approach for Adolescent Multilingual Learners

Purpose: Adolescent multilingual learners are at high risk for reading difficulties as evidenced by persistent achievement gaps. This article calls for a paradigm shift and aims to elucidate what constitutes promising second-language literacy instruction for multilingual adolescents, comprising effective literacy practices grounded in research, combined with an emphasis on individual learners and their sociocultural development. Cast in ecological systems and functionalist perspectives, this article provides a model for language and literacy instruction that is grounded in basic tenets of reading science within a sociocultural context. We outline strategies that focus on language as a basis for reading development followed by examples of authentic learning experiences designed to motivate students and nurture their love of reading. Conclusions: A solution to existing achievement gaps may be a promising approach that emphasizes both the science and love of reading, which entails targeted instruction rooted in the research evidence integrated into engaging and meaningful learning experiences, central to which is the acknowledgement of multilingual learners as individuals. The authors call for an intentional focus on accelerating the development of language through frequent use of and a genuine love for both the science of reading and the science of teaching reading.

Nationwide cross-sectional survey of patients with relapsing polychondritis in 2019 demonstrates reduction of airway involvement compared with that in 2009

We conducted retrospective cohort studies of patients with relapsing polychondritis (RP) twice in 2009 and 2019, using a physician questionnaire. We compared the patients’ clinical statuses between the years. Age and gender were comparable between the two surveys. Mean disease duration was longer in 2019 survey (8.3 years) than that in 2009 survey (4.8 years, P < 0.001). The mortality rate declined in 2019 survey compared with those in 2009 survey (from 9.2 to 1.6%, P < 0.001). Incidence of airway involvement decreased in 2019 survey compared with that in 2009 survey (from 49 to 37%, P = 0.012). In 2019 survey, we found more frequent use of biological agents and immunosuppressants in patients with airway involvement. When we focused on RP patients with airway involvement, physicians in 2019 chose methotrexate and calcineurin inhibitors preferentially, compared with azathioprine and cyclophosphamide. Of note is that increased use of infliximab was observed in RP patients with airway involvement, but not in those without. Reduction of airway involvement and mortality in patients with RP was observed in 2019 survey. The reduction may associate with the frequent use of biologics including infliximab in RP patients with airway involvement.

Ritual, Legend, and Metaphor: Narratives of the Willow in Yuan Zaju

Narratives of willow trees in Yuan zaju 雜劇, or variety play, largely come in three types, namely, the ritual performance of shooting willows; the deliverance of willow spirits by Lü Dongbin, one of the Eight Immortals of Daoism; and the use of the word willow to refer to women. The willow shooting ritual depicted in Yuan zaju was highly reminiscent of the willow shooting ritual popular throughout the Song (960–1279), Liao (916–1125), Jin (1115–1234), and Yuan (1271–1368) dynasties, with its conceptual origins traceable to the ancient shamanic belief in the willow as a sacred tree prevalent among the Khitans and Jurchens who lived in what is now northeastern China. The legend of Lü Dongbin delivering a willow spirit to immortality is a recurring motif in Han Chinese folklore and Daoist hagiography, which also finds expression in the iconic image of Guanyin Pusa or Bodhisattva Avalokitesvara holding a willow branch with which they cure diseases for people and bring fulfillment to their wishes. The frequent use of “willow leaf-shaped eyebrows” (liumei 柳眉) and “willow-like waist” (liuyao 柳腰) in Yuan zaju as metaphorical references to women can be seen as a continuation of the great literary tradition of Shijing 詩經 (The Book of Songs) and also as a dramatic enactment of the fertility cult of the willow and women in Chinese folk religion. Evidence abounds that the narratives about the willow in Yuan zaju were not a new creation but an artistic manifestation of centuries-old folk belief and literary tradition.

Study of Mechanical Properties of Recycled Polyethylene of High and Low Density

High and low density polyethylene materials constitute about 48% of total weight of plastics waste in Europe, that depends on the frequent use of these materials in packaging applications. This paper analyze the recycling effect on the mechanical properties of high and low density polyethylene (HDPE and LDPE). A mechanical recycling process was tested for the plastics waste of high and low density polyethylene, then a tensile and impact tests were performed on different mixing ratios for each of the both materials ranging from 100% of the virgin material and up to 100% of the recycled material with a difference of 10% of the sample to the other. This paper discusses the tensile properties of tensile stress at the fracture, elongation and modulus of elasticity and the impact test results for HDPE and LDPE were compared with each other.

Rythm-forming, functional and pragmatic potential and immanence of repetitions in the modern Spanish language

This article offers the results of the investigation of repetitions in the modern Spanish language. To understand the role of the repetitions in a certain text, first of all, it’s necessary to determine whether they are immanent in the language or culture, and, therefore, unmarked, or, on the contrary, carry some charge: stylistic, rhythmic or pragmatic. Such differentiation is carried out by means of the analysis and synthesis of the theoretic material (А. Аlonso, E. А. Llorach, J. Nogeira, V. Iovenko, V. Vinogradov, etc.), contrastive and comparative analysis. The results show the redundancy of the Spanish language in comparison with Russian, which accounts for the numerous unmarked repetitions in Spanish. On the other hand, the frequent use of repetitions as stylistic, semantic or rhythmic device becomes evident too. For the analysis, we chose some official documents, characterized by the absence of stylistic devices, and some appellative and literary texts (poetry by A. Carvajal, a novel by S. Puertolas, etc.), which are apriori aimed at the form and pragmatic effect. This approach helps achieve the most objective conclusions concerning the nature of the repetitions in a text. We considered lexical and grammar repetitions, grammar, semantic and concept repetitions. Phonetic and lexical repetitions, as the basic stylistic devices, have not been subjected to analysis, as their markedness is evident. The results of the research, presented in the article, may be useful both for the people studying the Spanish language in order to speak it correctly and to understand the pragmatic function of repetition, and for translators to decide whether to follow the structure and rhythm of the text if repetitions are marked, or to omit them when they are in the original text, should they be immanent in the language and the culture.

Barriers to the Use of Games-Based Learning in Pre-School Settings

The main aim of this research is to investigate how teachers perceive the barriers that limit the adoption and implementation of games-based learning in early childhood education on Cyprus. Teachers are working in public and private pre-schools. A 19-item questionnaire was administered to 148 early childhood teachers in Cyprus (78 public pre-school teachers and 70 private pre-school teachers). Factor analysis reveals three types of barriers to the use of games-based learning in early childhood classroom: lack of confidence, lack of support, and lack of equipment. The higher the teachers' self-efficacy in using digital games is, the lower the level of teachers' perception regarding the barrier lack of confidence becomes. Teachers with no frequent use of computer and digital games in the classroom perceive lack of confidence as a major barrier. Public pre-schools teachers have significantly more positive attitudes toward the usefulness of GBL than private pre-schools teachers.

Effects of osmolality and solutes on the morphology of red blood cells according to three-dimensional refractive index tomography

Phosphate-buffered saline (PBS) and Alsever’s solution (AS) are frequently used as media in blood-related studies, while 0.9% normal saline (NS) is frequently used in transfusion medicine. Despite the frequent use, the effects of these solutions on the shape and volume of red blood cells (RBCs) have not been reported. We collected blood samples from five healthy adults and used three-dimensional refractive index tomography to investigate the changes in the morphology of RBCs caused by changes in osmolality and solutes at the single-cell level. After diluting 2 μL of RBCs 200-fold with each solution (PBS, AS, and 0.9% NS), 40 randomly selected RBCs were microscopically observed. RBC shape was measured considering sphericity, which is a dimensionless quantity ranging from 0 (flat) to 1 (spherical). RBCs in plasma or AS showed a biconcave shape with a small sphericity, whereas those in 0.9% NS or PBS showed a spherical shape with a large sphericity. Moreover, we confirmed that sodium chloride alone could not elicit the biconcave shape of RBCs, which could be maintained only in the presence of an osmotic pressure-maintaining substance, such as glucose or mannitol. Although 0.9% NS solution is one of the most commonly used fluids in hematology and transfusion medicine, RBCs in 0.9% NS or PBS are not biconcave. Therefore, as the debate on the use of NS continues, future clinical studies or applications should consider the effect of glucose or mannitol on the shape of RBCs.
