What do you fantasize about? An exploratory factor analysis of minor attracted person's sexual fantasies.

Current knowledge on the sexual fantasies of minor attracted persons (MAPs) is primarily focused on these individuals' attraction to minors. Furthermore, MAPs' sexual fantasies are often perceived as revolving systematically around scenarios involving a minor. However, this raises the question of whether their sexual fantasies extend beyond minors. To explore this, we analyzed data from 403 MAPs (364 men and 39 women), using a modified Joyal Sexual Fantasy Questionnaire (JSFQ). Our exploratory factor analysis (EFA) revealed 5 factors: Male Partner Focused Fantasies (α = 0.905), Female Partner Focused Fantasies (α = 0.882), Coercing Focused Fantasies (α = 0.867), Promiscuous/Unattached Focused Fantasies (α = 0.848), and Romantic/Relational Sexual Fantasies (α = 0.650). These results not only highlight the diversity of MAPs' sexual interests of beyond their attraction to minors, paving the way for further research, but also suggest new perspectives for practitioners.

Localization of EFA6A, an exchange factor for Arf6, in Z-lines and sarcoplasmic reticulum membranes in addition to myofilaments in I-domains of skeletal myofibers of peri-natal mice.

Membrane trafficking and actin-remodeling are critical for well-maintained integrity of the cell organization and activity, and they require Arf6 (ADP ribosylation factor 6) activated by GEF (guanine nucleotide exchange factor) including EFA6 (exchange factor for Arf6). In the present immuno-electron microscopic study following previous immunohistochemical study by these authors (Chomphoo et al., 2020) of in situ skeletal myoblasts and myotubes of pre-and perinatal mice, the immunoreactivity for EFA6A was found to be localized at Z-bands and sarcoplasmic reticulum (SR) membranes in I-domains as well as I-domain myofilaments of skeletal myofibers of perinatal mice. Based on the previous finding that EFA6 anchored on the neuronal postsynaptic density via α-actinin which is known to be shared by muscular Z-bands, the present finding suggests that EFA6A is also anchored on Z-bands via α-actinin and involved in the membrane trafficking and actin-remodeling in skeletal myofibers. The localization of EFA6A-immunoreactivity in I-domain SR suggests a differential function in the membrane traffic between the I- and A-domain intracellular membranes in perinatal skeletal myofibers.

Over a decade of UAV incidents: A human factors analysis of causal factors.

This analysis examined systemic causes of Uncrewed Air Vehicle (UAV) accidents identifying operator, environmental, supervisory, and organisational factors through the use of the Human Factors Analysis and Classification System (HFACS). HFACS is a system-based analysis method for investigating the causal factors associated with accidents and incidents and has previously been used to reliably and systematically identify active and latent failures associated with both military and general aviation accidents. Whilst HFACS has previously been applied to UAV accidents, the last known application was conducted in 2014. Using reports retrieved from nine accident investigation organisations' databases, causal factors were coded against unsafe acts, preconditions, and failures at the supervisory, organisational, and environmental levels. Causal factors were assessed on 77 medium or large UAV mishaps/accidents that occurred over a 12-year period up to 2024. 42 mishap reports were deemed to involve a human factor as a causal factor. A large proportion of the mishaps contained factors attributed to Decision Errors at level 1 (Unsafe Acts) which was found to be associated with both the Technological Environment and Adverse Mental State at level 2 (Pre-conditions). Causal factors were identified at each of the other 3 levels (Supervisory, Organisational and External) with a number of emergent associations between causal factors. These data provide support for the identification and development of interventions aimed at improving the safety of organisations and advice of regulators for Uncrewed Air Systems.

Stakeholders' perspectives on critical success factors for environmental social and governance (ESG) implementation.

Environmental Social and Governance (ESG) has emerged as a sensitive issue, attracting the attention of a large audience that could not be ignored. Government bodies continue to pass regulations mandating organizations to comply with ESG principles. However, many organizations have had unsatisfactory results while promoting sustainability ideals due to various challenges. To achieve ESG goals, the present study offers a thorough framework for ESG implementation across organizations based on the critical success factor (CSF) theory and the opinions of diverse stakeholders. Following a literature review and brainstorming with ESG experts and academicians, a survey questionnaire was sent to 400 respondents to evaluate the 20 factors identified as 'super-set' CSFs for ESG implementation. This paper represents a novel attempt in ESG research as it conducts a survey supported by exploratory factor analysis (EFA). The interactions between the significant CSFs were studied by employing total interpretative structural modeling (TISM) and fuzzy MICMAC approach. ESG implementation is found to be highly driven by firm characteristics, earnings quality, and environmental performance, which can be argued to be the fundamental determinants of ESG implementation. According to these findings, organizations' leadership should (1) focus on effectively structuring firms' attributes to swiftly operate the ESG implementation framework, (2) ensure consistent business earnings that signal improved future performance, and (3) continuously monitor and assess their environmental performance. These efforts should be supported by engaging with diverse stakeholder groups, each playing its respective role in ESG implementation. Consequently, ESG implementation across organizations is anticipated to accelerate with thoughtful organizational coordination, strategic planning, and compliance with authoritative policies. However, rather than solely focusing on creating ESG disclosure laws, policymakers should also focus on creating better ESG outcomes through effective ESG implementation. Therefore, this research offers valuable insights into improving ESG practices, which facilitates the adoption of mandatory ESG disclosure regulations.

EFA6A, an Exchange Factor for Arf6, Regulates NGF-Dependent TrkA Recycling From Early Endosomes and Neurite Outgrowth in PC12 Cells.

Endosomal trafficking of TrkA is a critical process for nerve growth factor (NGF)-dependent neuronal cell survival and differentiation. The small GTPase ADP-ribosylation factor 6 (Arf6) is implicated in NGF-dependent processes in PC12 cells through endosomal trafficking and actin cytoskeleton reorganization. However, the regulatory mechanism for Arf6 in NGF signaling is largely unknown. In this study, we demonstrated that EFA6A, an Arf6-specific guanine nucleotide exchange factor, was abundantly expressed in PC12 cells and that knockdown of EFA6A significantly inhibited NGF-dependent Arf6 activation, TrkA recycling from early endosomes to the cell surface, prolonged ERK1/2 phosphorylation, and neurite outgrowth. We also demonstrated that EFA6A forms a protein complex with TrkA through its N-terminal region, thereby enhancing its catalytic activity for Arf6. Similarly, we demonstrated that EFA6A forms a protein complex with TrkA in cultured dorsal root ganglion (DRG) neurons. Furthermore, cultured DRG neurons from EFA6A knockout mice exhibited disturbed NGF-dependent TrkA trafficking compared with wild-type neurons. These findings provide the first evidence for EFA6A as a key regulator of NGF-dependent TrkA trafficking and signaling.

Raman spectra soft modeling of the biodiesel oxidation through evolving factor analysis & multivariate curve resolution.

The oxidative stability of biodiesel is defined by its relative resistance to the action of oxygen at room temperature. Its determination is an essential reference to the quality of biofuel and a significant parameter to be determined. This parameter concerns the quality of the biodiesel to be supplied to the consumer, and its determination is fundamental to maintaining the engine's proper functioning. Raman spectroscopy allows the rapid obtaining of structural information regarding biodiesel quality and, when aided by multivariate analysis methods, allows a quantitative determination of specific properties. This work uses Raman spectroscopy, Multivariate Curve Resolution with Alternative Least Squares (MCR-ALS) method, and Evolving Factor Analysis (EFA) to study biodiesel's oxidation kinetics. Also, the vibrational modes C = C, CH2, and CH3 were identified as the main structural groups involved in this process, corroborating previous studies. The MCR-ALS & EFA combination allowed modeling of the degradation kinetics following an A â†’ B â†’ C mechanism, where A corresponds to the biodiesel (starting material), B is related to the hydroperoxide mixture, and C is the final product. The results also suggested that this process follows a first-order reaction, with kinetic constant values of k1 = 0.0056 min-1 and k2 = 0.0031 min-1.

Exploratory factor analysis of the Illness Intrusiveness Rating Scale for parents of children with atypical genital appearance due to differences of sex development (DSD).

OBJECTIVE: Illness intrusiveness refers to the subjective cognitive appraisal of a chronic health condition interfering in daily, valued activities and may be highly relevant for parents of children with atypical genital appearance due to differences of sex development (DSD). However, a measure of illness intrusiveness has not been validated for this population. The current study aimed to evaluate the factor structure of the Illness Intrusiveness Scale for Parents (IIS-P) and examine convergent validity. METHODS: Participants included 102 parents (Mage = 33.39 years, SD = 6.48; 58% mothers) of 65 children (<2 years old) diagnosed with DSD participating in a larger, longitudinal study. Parents completed the IIS-P as well as self-report measures of stigma, and anxious and depressive symptoms. An exploratory factor analysis (EFA) was conducted. RESULTS: EFA results supported a 1-factor intrusiveness solution (α = .93), as well as a 2-factor solution measuring intrusiveness on daily living (α = .92) and community connectedness (α = .85). The 1-factor solution and both factors of the 2-factor solution demonstrated significant convergent validity with stigma as well as anxious and depressive symptoms. CONCLUSIONS: Support emerged for both 1- and 2-factor solutions of the IIS-P in parents of children with DSD. The decision to evaluate illness intrusiveness as a total score or to examine the subscales of daily living and community connectedness should be tailored to the unique aims of researchers and clinicians. Future research should conduct a confirmatory factor analysis with both 1- and 2-factor models with larger, more diverse samples of caregivers.

From everyday life to measurable problematic smartphone use: The development and validation of the Smartphone Use Problems Identification Questionnaire (SUPIQ).

Background and aims: Problematic smartphone use (PSU) has gained attention, but its definition remains debated. This study aimed to develop and validate a new scale measuring PSU-the Smartphone Use Problems Identification Questionnaire (SUPIQ). Methods: Using two separate samples, a university community sample (N = 292) and a general population sample (N = 397), we investigated: (1) the construct validity of the SUPIQ through exploratory and confirmatory factor analyses; (2) the convergent validity of the SUPIQ with correlation analyses and the visualized partial correlation network analyses; (3) the psychometric equivalence of the SUPIQ across two samples through multigroup confirmatory factor analyses; (4) the explanatory power of the SUPIQ over the Short Version of Smartphone Addiction Scale (SAS-SV) with hierarchical multiple regressions. Results: The results showed that the SUPIQ included 26 items and 7 factors (i.e., Craving, Coping, Habitual Use, Social Conflicts, Risky Use, Withdrawal, and Tolerance), with good construct and convergent validity. The configural measurement invariance across samples was established. The SUPIQ also explained more variances in mental health problems than the SAS-SV. Discussion and conclusions: The findings suggest that the SUPIQ shows promise as a tool for assessing PSU. Further research is needed to enhance and refine the SUPIQ as well as to investigate its clinical utility.

Monthly variation of fatty acids, lipid quality index and metal content of Pontastacus leptodactylus (Eschscholtz, 1823) in Atikhisar Dam Lake (Çanakkale, Türkiye).

This study aims to investigate the metal content, fatty acid composition, lipid quality, and potential health risks of Pontastacus leptodactylus crayfish inhabiting Atikhisar Dam Lake. The research covers a 12-month period and includes both male and female individuals. The study investigated the metal content of crayfish specimens. In female individuals, the metal concentrations were ranked as Fe > Zn > Al > Cu > Mn > Se > As > Hg > Cd > Pb, while in male individuals, the ranking was Fe > Al > Zn > Cu > Mn > Se > As > Hg > Pb > Cd. The results demonstrate that Atherogenicity Index (AI) values for both genders range between 0.21 and 0.31, and Thrombogenicity Index (TI) values fall within 0.14 and 0.20. This indicates that crayfish meat is composed of healthy and high-quality fatty acids. In male individuals, omega-3 values range from 25.28 ± 0.380% to 28.34 ± 0.430%, and in female individuals, they vary from 22.98 ± 0.195% to 28.73 ± 0.871%. These findings underscore the absence of significant health risks associated with mercury levels in crayfish meat. Monthly meal calculations reveal that consuming female crayfish at an average of 4.35 servings per month for adults and 2.24 servings per month for children presents no health hazards. Similarly, the consumption of crayfish meat at an average of 5.29 servings per month for adult males and 2.72 servings per month for male children is deemed safe for health. Based on these results, the lipid quality of both male and female individuals from this species is found to be beneficial, as confirmed by risk-benefit assessments.

Psychometric properties of the Interpersonal Emotion Regulation Questionnaire in a community sample of the Portuguese population.

BACKGROUND: Intrapersonal aspects of emotion regulation have been at the forefront of research, while interpersonal aspects have received less attention. The Interpersonal Emotion Regulation Questionnaire (IERQ) was developed to address this issue. However, this scale was neither adapted nor validated for European Portuguese. AIMS: The present study aims to adapt the IERQ to European Portuguese and explore the preliminary psychometric properties of the IERQ in a community sample, through confirmatory factor analysis (CFA). Construct validity was further supported by examining convergent validity with ERQ subscales. METHOD: Using a cross-sectional design, individuals were recruited online. Self-report questionnaires were used, namely the IERQ and the Emotion Regulation Questionnaire (ERQ). RESULTS: The four-factor structure was confirmed through CFA. IERQ subscales correlated positively with the dimensions of the ERQ of cognitive reappraisal and correlated negatively with experiential suppression. CONCLUSIONS: This preliminary study showed that the IERQ has adequate psychometric properties in a Portuguese sample and supports that this instrument can be used to assess interpersonal emotion regulation strategies in non-clinical samples.
