Purpose Nursing is traditionally considered a female profession, and male nursing students face gender stereotype barriers. Most studies of male nursing students in Japan focus on their learning experiences in maternal nursing, and little is known about the experiences of male nursing students in their usual learning environment. Therefore, the purpose of this study is to explore the barriers and coping strategies of Japanese male nursing students in nursing education, including classroom and practical training. Methods A qualitative descriptive design was used to study 20 male nursing students from eight Japanese universities. Purposive sampling using the snowball method was used to recruit participants. Semistructured interviews were used to gather data about the participants’ thoughts and experiences in nursing education. All interview data were analyzed using thematic analysis. Results Four themes emerged from the data: (1) nursing choices of own volition; (2) loneliness due to the female-dominated environment and marginalization; (3) dealing with barriers and seeking support; and (4) positive experiences in nursing education. Male nursing students face barriers such as loneliness and feelings of alienation. Family support, mutual support among male nursing students, and the presence of role models were factors that addressed these barriers and positively influenced career choice. Conclusions This research suggests that nursing educators need to understand the barriers faced by male nursing students and provide a gender-neutral learning environment for all students.
Discriminating leptonic Yukawa interactions with doubly charged scalar at the ILC
Nomura, Takaaki,Okada, Hiroshi,Yokoya, Hiroshi Elsevier 2018 Nuclear Physics, Section B Vol.929 No.-
<P><B>Abstract</B></P> <P>We explore discrimination of two types of leptonic Yukawa interactions associated with Higgs triplet, L ¯ L c Δ <SUB> L L </SUB> , and with S U ( 2 ) singlet doubly charged scalar, e ¯ R c <SUP> k + + </SUP> <SUB> e R </SUB> . These interactions can be distinguished by measuring the effects of doubly charged scalar boson exchange in the <SUP> e + </SUP> <SUP> e − </SUP> → <SUP> ℓ + </SUP> <SUP> ℓ − </SUP> processes at polarized electron-positron colliders. We study a forward-backward asymmetry of scattering angular distribution to estimate the sensitivity for these effects at the ILC. In addition, we investigate prospects of upper bounds on the Yukawa couplings by combining the constraints of lepton flavor violation processes and the <SUP> e + </SUP> <SUP> e − </SUP> → <SUP> ℓ + </SUP> <SUP> ℓ − </SUP> processes at the LEP and the ILC.</P>
Diphoton resonances at the ILC
Tian, Junping,Fujii, Keisuke,Yokoya, Hiroshi American Physical Society 2016 Physical review. D Vol.94 No.9
<P>In this paper, we study the direct production of the diphoton resonance X, which was suggested by 2015 data at the LHC, in e(+)e(-) -> X gamma/XZ processes at the ILC. We derive an analytic expression for the scattering amplitudes of these processes and present a comprehensive analysis for determining the properties of X at the ILC. A realistic simulation study for e(+)e(-) -> X gamma is performed based on the full detector simulation to demonstrate the capabilities of the ILC experiment. Complementary to the searches at the LHC, prospects for the measurement of the absolute values of the production cross section are obtained for the ILC using the recoil technique without assuming decay modes of X. In addition, we studied the searches for X -> invisible and X -> b (b) over bar modes, which are challenging at the LHC, and found that these decay modes can be discovered with high significance if their branching ratios are large enough.</P>
Family gauge boson production at the LHC
Koide, Y.,Yamanaka, M.,Yokoya, H. North-Holland Pub. Co 2015 Physics letters. Section B Vol.750 No.-
Family gauge boson production at the LHC is investigated according to a U(3) family gauge model with twisted family number assignment. In the model we study, a family gauge boson with the lowest mass, A<SUB>1</SUB><SUP>1</SUP>, interacts only with the first generation leptons and the third generation quarks. (The family numbers are assigned, for example, as (e<SUB>1</SUB>,e<SUB>2</SUB>,e<SUB>3</SUB>)=(e<SUP>-</SUP>,μ<SUP>-</SUP>,τ<SUP>-</SUP>) and (d<SUB>1</SUB>,d<SUB>2</SUB>,d<SUB>3</SUB>)=(b,d,s) [or (d<SUB>1</SUB>,d<SUB>2</SUB>,d<SUB>3</SUB>)=(b,s,d)].) In the model, the family gauge coupling constant is fixed by relating to the electroweak gauge coupling constant. Thus measurements of production cross sections and branching ratios of A<SUB>1</SUB><SUP>1</SUP> clearly confirm or rule out the model. We calculate the cross sections of inclusive A<SUB>1</SUB><SUP>1</SUP> production and bb@?(tt@?) associated A<SUB>1</SUB><SUP>1</SUP> production at s=14 TeV and 100 TeV. With the dielectron production cross section, we discuss the determination of diagonalizing matrix of quark mass matrix, U<SUB>u</SUB> and U<SUB>d</SUB>, respectively.
