The Direct/Indirect Association of ADHD/ODD Symptoms with Self-esteem, Self-perception, and Depression in Early Adolescents

The present study aimed to reveal the influences of attention-deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) symptoms on self-esteem and self-perception during early adolescence and to clarify the spillover effect of self-esteem on depressive symptoms. ADHD symptoms in 564 early adolescents were evaluated via teacher-rating scales. Self-esteem and depressive symptoms were assessed via self-reported scales. We analyzed the relationships among these symptoms using structural equation modeling. Severe inattentive symptoms decreased self-esteem and hyperactive–impulsive symptoms affected self-perception for non-academic domains. Although these ADHD symptoms did not directly affect depressive symptoms, low self-esteem led to severe depression. ODD symptoms had a direct impact on depression without the mediating effects of self-esteem. These results indicated that inattentive symptoms had a negative impact on self-esteem and an indirect negative effect on depressive symptoms in adolescents, even if ADHD symptoms were subthreshold. Severe ODD symptoms can be directly associated with depressive symptoms during early adolescence

“Principles” is the beginning of “philosophy” : A viewpoint from Descartes and toward the future of “physical education philosophy”

　This article attempts to clarify the conceptual difference between“ principles” and“philosophy” from the viewpoint of Descartes and history of the discipline of the“Principles of Physical Education.” The conclusion of this paper will lead us to reconsider the mission of the discipline of “Physical Education Philosophy,” according to its fundamental academic character.　In the field of“ Principles of Physical Education” in Japan, research has continued since the beginning of the twentieth century from the viewpoint of the philosophical method, whereas, in other countries, “Principles of Physical Education” consistently offers some practical knowledge, which is not necessarily philosophical. For a long time, most Japanese researchers have thought of the concepts of “principles” and “philosophy” as the same. However, using Descartes’ Principles of Philosophy, this paper will show that the concepts of “principles” and “philosophy” are totally different. It will become necessary to articulate a clear difference between these things, and to offer some basic academic character to the discipline of “Physical Education Philosophy,” which changed its name from “Principles of Physical Education” in 2005.　According to Descartes, principles are what we would see as the beginning point of philosophy. Philosophy has its root in principles and principles is a part of philosophy, but not the same as philosophy. Philosophy, for Descartes, also has utility for our everyday affairs. He argued that wisdom should be produced from philosophy as practical knowledge. He also presented examples of this in his own writings, such as Dioptric, Meteorology, and Geometry. If we follow Descartes’ view, the discipline of “Physical Education Philosophy” should change its academic character, because so far it has retained the academic character of the previous“Principles of Education.” Researchers of “Physical Education Philosophy” should produce their own output, not only offering some fundamental knowledge for those who engage in physical education and sport, but also offering wisdom as a practical knowledge to practitioners in order to direct their basic thinking.　This will lead to a more enlightened discussion. Spiritual Exercises, proposed by Pierre Hadot, presents a type of essence of wisdom as practical knowledge, which will lead us to reconsider the nature of wisdom in the context of physical education and sport

Chiral Soliton Lattice Formation in Monoaxial Helimagnet Yb(Ni1−x_{1-x}Cux_x)3_3Al9_9

Helical magnetic structures and its responses to external magnetic fields in Yb(Ni$_x$Cu$_{1-x}$)$_3$Al$_9$, with a chiral crystal structure of the space group $R32$, have been investigated by resonant X-ray diffraction. It is shown that the crystal chirality is reflected to the helicity of the magnetic structure by a one to one relationship, indicating that there exists an antisymmetric exchange interaction mediated via the conduction electrons. When a magnetic field is applied perpendicular to the helical axis ($c$ axis), the second harmonic peak of $(0, 0, 2q)$ develops with increasing the field. The third harmonic peak of $(0, 0, 3q)$ has also been observed for the $x$=0.06 sample. This result provides a strong evidence for the formation of a chiral magnetic soliton lattice state, a periodic array of the chiral twist of spins, which has been suggested by the characteristic magnetization curve. The helical ordering of magnetic octupole moments, accompanying with the magnetic dipole order, has also been detected.Comment: 13 pages, 18 figures, accepted for publication in J. Phys. Soc. Jp

Boolean Gröbner bases

In recent years, Boolean Gröbner bases have attracted the attention of many researchers, mainly in connection with cryptography. Several sophisticated methods have been developed for the computation of Boolean Gröbner bases. However, most of them only deal with Boolean polynomial rings over the simplest coefficient Boolean ring View the MathML source. Boolean Gröbner bases for arbitrary coefficient Boolean rings were first introduced by two of the authors almost two decades ago. While the work is not well-known among computer algebra researchers, recent active work on Boolean Gröbner bases inspired us to return to their development. In this paper, we introduce our work on Boolean Gröbner bases with arbitrary coefficient Boolean rings
