Motivation to lead in Japan: validation of a Japanese version of the motivation to lead scale
Authors: Tanaka Satoshi , Hatano Kai , Ikeda Megumi , Nakahara Jun 
Published: January 2024

IntroductionThis study aimed to develop a Japanese version of the motivation to lead (MTL) scale consisting of three factors−affective-identity MTL, non-calculative MTL, and social-normative MTL−and examine its construct validity and reliability.MethodsThe participants comprised 500 university students and 500 employees aged 20–29 years registered with a Japanese research company.ResultsBased on a confirmatory factor analysis, the three-factor model was found to be appropriate for the Japanese context. The measurement invariance analyses indicated scalar invariance between students and employees and between men and women. Finally, the correlation analysis with the Big Five personality traits conducted to examine construct validity indicated that affective-identity MTL and social-normative MTL had significant relationships with all five traits (extraversion, agreeableness, conscientiousness, open-mindedness, and negative emotionality). Although non-calculative MTL was not significantly correlated, it can be interpreted in the Japanese context.DiscussionThe results indicate the adequate construct validity and reliability of the Japanese version of the MTL scale. These findings hold significant implications for leadership development and selection in Japan, highlighting the motivational factors that drive effective leadership.

IntroductionPersonality is a central factor associated with relationship discord, conflicts, and separation, as well as with dyadic adjustment and relationship stability. The Alternative Model for Personality Disorders (AMPD) of the DSM-5 offers a hybrid model for understanding personality based on personality dysfunction (Criterion A) and pathological domains and facets (Criterion B). So far, few studies have integrated this model into the understanding of relationship quality. Therefore, the aim of this study was to examine the contribution of Criterion B to relationship satisfaction in individuals involved in an intimate relationship. We also explored the joint contribution of Criteria A and B, as well as their interaction effects, to relationship satisfaction.MethodsParticipants were drawn from two clinical samples: patients with personality disorders (PD; N = 101) and clients consulting in private practice clinics (PPC; N = 350). They completed self-report questionnaires assessing relationship satisfaction and AMPD Criteria A (only for PPC sample) and B.ResultsHierarchical regressions showed that, for the PD sample, the Detachment and Negative Affectivity domains, especially the pathological facets of Intimacy Avoidance and Separation Insecurity, explained 22.5% of relationship satisfaction’s variance. For PPC clients, Detachment, Negative Affectivity, and Antagonism domains, and especially the pathological facets of Intimacy Avoidance, Anxiousness, and Grandiosity, contribute significantly to relationship satisfaction, explaining 14.8% of its variance. Criterion A elements did not evince incremental value to the regression models in the PPC sample, and no Criteria A and B interaction effects were found. Clinical implications as well as limitations of the study are discussed.

IntroductionGrowing anecdotal evidence suggests the feasibility of robotic intervention for people who suffer from disorders related to state anxiety. Few studies have been conducted on utilizing robots for persons who stutter (PWS). The present study examines the feasibility of using a robot for speech therapy for PWS.MethodsWe prepared four settings (i.e., interviews with unfamiliar persons, interviews with unfamiliar communication robots, reading sentences aloud with a tandem robot that can utter the same words as a user by repeating the user’s voice after a short delay, and reading sentences aloud while being alone). We assessed the potential of the robots as both interlocutors and practice partners in training with delayed auditory feedback (DAF) for PWS. Moreover, we assessed the relationship between the trait of stuttering and the participants’ affinity to the robots.ResultsEleven PWS participated in the study. Eight (72.7%) participants had fewer stuttering-related psychological symptoms when they communicated with robots than when they communicated with humans. Spearman’s rank correlation analysis revealed that there was a significant negative correlation between the Modified Erickson Communication Attitude scale (S-24) and the difference between the scores for stuttering-related psychological symptoms pertaining to the communication robot and humans (p &lt; 0.01). Six participants (54.5%) had fewer stuttering-related psychological symptoms when they read aloud with the tandem robot than when they read aloud alone. There were significant positive correlations between S-24 and the differences between the scores for stuttering-related psychological symptoms when reading aloud with the tandem robot and those when reading aloud alone (p &lt; 0.01).DiscussionThe communication robot and tandem utterance robot can sometimes be burdensome, although both robots were always easier to talk to for PWS in this preliminary study. The participants with positive speech-related attitudes were more inclined to decrease stuttering-related psychological symptoms when communicating with CommU than when communicating with humans. The participants whose speech-related attitudes were negative were more inclined to show a decrease in stuttering-related psychological symptoms when reading aloud with the tandem robot. Further studies are needed to provide more detailed information.

IntroductionLower back pain is common worldwide and affects over 600,000 people annually, including teachers. The study aimed to investigate the prevalence of low back pain and disability among secondary school teachers in the Eastern Province of the Kingdom of Saudi Arabia.Materials and methodsThis cross-sectional study included secondary school teachers in the eastern province of Saudi Arabia. 34 schools were selected using a multistage stratified sampling approach. Teachers were allotted randomly and proportionally to each school. Data was collected by anonymous questionnaire having three elements: sociodemographic and health-related questions, the Standardized Nordic Questionnaire, and the Oswestry Low Back Pain Disability Questionnaire. The anthropometric data was also included. Both unadjusted and adjusted logistic regression analyses were performed.ResultsA total of 601 teachers participated in the study with 62.56% reported low back pain. The overall mean age was 40.31 ± 8.13 years. The male-to-female ratio was similar. Back pain was significantly higher among females than males (73.36 and 51.52%, respectively). Additionally, back pain will significantly increase when stress levels and the number of classes increases. A positive correlation was found between age with low back pain (p = 0.001).There was minimal disability in 64.63% of the 376 teachers who reported low back pain, moderate disability in 29.79%, and severe disability in 4.79%, and only three (0.8%) were considered crippled. Females were more frequently seen in moderate and crippled categories, and perceived stress levels generally increased mean disability scores. Age and female gender were revealed to be significant predictors of low back pain by logistic regression (adjusted odds ratio [OR] = 1.04, 95% confidence interval [CI] = 1.02–1.07) and (adjusted OR = 2.11, 95% CI = 1.45–3.05), respectively. The number of classes per week was also a significant predictor.ConclusionThis study adds to the epidemiological evidence that reveals a high prevalence of low back pain and disability among teachers. Identified risk factors in this study may also reinforce the importance of setting different interventions and preventive measures to reduce lower back pain risk.

Abstract
This paper discusses the basic properties of a surface acoustic wave (SAW) mode like the zeroth-order symmetric (S0) Lamb mode in the LiNbO3/SiO2/SiC configuration in detail. At first, the influence of the SiO2 insertion is discussed, and it is shown that SiO2 insertion offers significant enhancement of the electromechanical coupling coefficient K
2 for the S0-like SAW mode without significant reduction of the phase velocity. Then, the discussion is extended to spurious resonance characteristics. It is shown that the dummy electrodes are not necessary in this case. Then, two kinds of piston design are applied for the transverse suppression, and their effectiveness is discussed.

Published: January 2024

The influence of three types of α­alumina, which differ in dispersion — the specific surface area of particles of 1, 3, and 5 m2/g (two of them are active alumina) and their amount (up to 4 %) on the main properties of samples from fused ZrO2 stabilized with ~10 % Y2O3, fired at 1580 °C was studied. The optimum additive, as well as its amount (1 % alumina of lower dispersion), which ensures the production of fired samples with high property indicators, were determined: content of ZrO2 + HfO2 87.80 wt. %, Y2O3 9.20 wt. %, Fe2O3 0.15 wt. %, apparent density 4.71 g/cm3, open porosity 21.0 %, cold crushing strength 31 N/mm2, thermal shock resistance 13 heat cycle (1300 °C — water). No significant advantage of the Al2O3 additive in the form of active alumina has been established, so less dispersed alumina is preferred for economic reasons.
As a result of the research performed at JSC “URIR named after A. S. Berezhnoy” institution, the technology of products made of fused ZrO2 stabilized with ~10 % Y2O3 was improved, which ensures the production of these products with a higher (although slightly) cold crushing strength and ~3 times higher thermal shock resistance (1300 — water) compared to similar characteristics of currently manufactured products. This can ensure a longer service life of refractories made of fused ZrO2 stabilized with ~10 % Y2O3 and with Al2O3 additive (due to their much higher thermal shock resistance compared to refractories of the same composition but without Al2O3 additive) in various thermal units at consumers’ facilities where this characteristic of refractories is most important.
Based on the study results, regulatory documentation was developed and full­scale samples of industrial­format products were manufactured.

The influence of additives amount (1—5 %) of two dispersed a­form active alumina with practically the same chemical composition but with different dispersion (specific surface area of 3.0 and 5.0 m2/g) on the moisture content of vibrocasting coarse­grained low­cement alumina­chromia castable mass (masses without the mentioned additives and with 1—5 % additive), on the strength of its structure 30, 60 and 90 minutes after the mass preparation and the effect on main properties of vibrocast castable samples from it (masses with an addition of 5 % of the mentioned alumina) both the unfired (cold crushing strength after hardening in humid conditions for 1; 3; 7 days) and fired at a temperature of 1580 °C ones (open porosity, apparent density, cold crushing strength) was studied. It was established that an increase in the amount of both active alumina and an increase in their dispersion leads to a gradual natural tendency to reduce the moisture content of masses while improving their flowing compared to the mass without the addition of dispersed active alumina; obtaining high strength of the mass structure, and higher with the addition of more dispersed alumina; improving the properties of unfired castable compared to castable without the addition of dispersed active alumina. More dispersed alumina was more effective both in reducing the moisture content of castable and improving its properties. The practicality of introducing dispersed active alumina of one of the studied grades into castable was shown.
Based on the research results, an improved technology for manufacturing by vibrocasting castable products from low­cement alumina­chromia castable mass containing an active alumina additive was developed. This technology ensures the production of unfired and fired products with improved properties. The technical documentation was developed and the raw material base for the production of low­cement alumina­chromia castable was expanded.

Published: January 2024

The effect of dispersing and strengthening additives on the rheological properties of aqueous slips made from new brands of alumina produced by a German company was studied. The optimal quantities of dispersing additive for slips from all researched new brands of alumina were determined: for less dispersed alumina — 0.3 % and more dispersed alumina — 0.4 %, the introduction of which reduces the dynamic viscosity of slips to minimum values of — 30 mPa·s, 70 mPa·s and 110 mPa·s, respectively. It has been established that slips made from all researched new brands of alumina with the optimal dispersing additive quantity are characterized by high sedimentation stability and in combination with 0.2 % strengthening additive the sedimentation stability of slips increases.
The main properties indexes of the samples from new brands of alumina before and after firing at a temperature of 1580 °C were determined. It was established that green samples from new brands of alumina are characterized by apparent density 2.23 g/cm3, 2.19 g/cm3, 2.18 g/cm3 and cold crushing strength 1.1 N/mm2, 1.0 N/mm2, 0.8 N/mm2, respectively, and samples after firing at 1580 °C by apparent density 3.75 g/cm3, 3.90 g/cm3, and 3.86 g/cm3, open porosity 3.3 %, 0.5 %, 0.4 % and bending strength 150 N/mm2, 180 N/mm2, 200 N/mm2, respectively.
As a result of the performed research, it was established that new brands of more dispersed alumina are suitable for the production by the slip casting method in plaster molds of alumina ceramics with open porosity up to 0.5 % and bending strength ~ 180—200 N/mm2.
According to the performed research results the technology of alumina ceramics by slip casting in plaster molds method was improved and the raw material base for its production was expanded.

A prótese bucomaxilofacial (P.B.M.F,) facial é uma especialidade da odontologia responsável pela reabilitação oral, facial e funcional com próteses extraorais e intra-oraisintraorais de pacientes com defeitos maxilofaciais. A escassez de profissionais especializados é crítica, pois durante um tratamento de uma neoplasia maligna pode ocorrer a perda de estrutura da face, onde o profissional especializado tem a possibilidade de reabilitar proteticamente a parte perdida seja ela de globo ocular, oculopalpebral, auricular, nasal, obturadora de palato visando a melhora da auto estima e a reintegração social do paciente. O contato com a disciplina é importante para a evolução da especialidade, assim como interesse de graduandos e discentes. A P.B.M.F tem um papel importante na reintegração social de um paciente mutilado pela neoplasia bucal nos dias de hoje. O avanço da odontologia estética veio com a necessidade de se enaltecer uma aparência mais bela, harmoniosa e mais jovem de um paciente que se enquadra nos padrões de beleza. Em contrapartida, o paciente com perda de parte da face que lutou, com um diagnóstico que ameaçou sua vida, busca se tornar imperceptível no meio da multidão. O objetivo deste trabalho é realizar uma revisão de literatura expondo a necessidade do contato dos profissionais e acadêmicos com a P.B.M.F. e os tipos de próteses usadas. A metodologia se baseou em dados retirados das plataformas Scielo, Pubmed e Google Acadêmico dos últimos 10 anos, sendo encontrados artigos que na sua maioria eram relatos de caso. A prótese maxilofacial é um ramo da prótese dentária associada à restauração e/ou substituição de estruturas estomatognáticas e craniofaciais por próteses, que podem ou não ser removidas de forma regular ou eletiva.
