Effect of Individual Differences in Construal Level on Procrastination: Moderating Role of Intelligence Theories  [PDF]
Miki Terada
Psychology (PSYCH) , 2017, DOI: 10.4236/psych.2017.84032
Abstract: The relationship between individual differences in construal level and self-control, including procrastination was investigated by examining the following hypotheses. 1) People with high level of construal would procrastinate less when learning a task than those with low level of construal; and 2) theories of intelligence would moderate the effect of construal level on procrastination. These hypotheses were tested by using survey data. Results indicated that people with a low construal level procrastinated more. Results also indicated the moderating role of intelligence theories on the relationship between Behavior Identification Form (BIF) score and procrastination. This study is expected to expand our understanding of construal level theory and individual differences. The findings are also expected to clarify the relationship between construal level and procrastination.
Variations of multifractal structure in the fetal heartbeats.

Acta Medica Okayama , 2003,
Abstract: Several procedures for evaluating fetal well-being are in clinical use. The cardiotocograph is mostly used as a non-invasive procedure to measure fetal well-being in clinical settings. The cardiotocograph displays the fetal heartbeat counts that vibrate. This variation has been classified into 2 categories. We investigated this variation by a novel method, in which we analyzed the change of structure of the attractors in the phase spaces according to the time course. We adopted the global spectrum, which means the distribution of fractal dimensions, for that structure. In this procedure, we discovered a new variation in which the cycle is much longer than the 2 types of known variabilities. Although loud noises such as white noises with a magnitude 1/4 times as large as the standard deviation of the original data were added to the original data, the variations were still detected. The variation is very difficult to detect by Fourier or wavelet transformation, however, because it changes very slowly. Through this new way of analyzing the vibration phenomena, we obtained a new perspective on the biological information available.
Electron dynamics during substorm dipolarization in Mercury's magnetosphere

Annales Geophysicae (ANGEO) , 2005,
Abstract: We examine the nonlinear dynamics of electrons during the expansion phase of substorms at Mercury using test particle simulations. A simple model of magnetic field line dipolarization is designed by rescaling a magnetic field model of the Earth's magnetosphere. The results of the simulations demonstrate that electrons may be subjected to significant energization on the time scale (several seconds) of the magnetic field reconfiguration. In a similar manner to ions in the near-Earth's magnetosphere, it is shown that low-energy (up to several tens of eV) electrons may not conserve the second adiabatic invariant during dipolarization, which leads to clusters of bouncing particles in the innermost magnetotail. On the other hand, it is found that, because of the stretching of the magnetic field lines, high-energy electrons (several keVs and above) do not behave adiabatically and possibly experience meandering (Speiser-type) motion around the midplane. We show that dipolarization of the magnetic field lines may be responsible for significant, though transient, (a few seconds) precipitation of energetic (several keVs) electrons onto the planet's surface. Prominent injections of energetic trapped electrons toward the planet are also obtained as a result of dipolarization. These injections, however, do not exhibit short-lived temporal modulations, as observed by Mariner-10, which thus appear to follow from a different mechanism than a simple convection surge.
Rejection Sensitivity, Self-Efficacy, and Learning Strategy: Mediating and Moderating the Role of Basic Needs Satisfaction  [PDF]
Miki Terada, Taishi Kawamoto
Psychology (PSYCH) , 2017, DOI: 10.4236/psych.2017.83028
Abstract: Rejection sensitive people often experience interpersonal difficulties, resulting in dissatisfaction with their need for relatedness. However, whether they are satisfied with their autonomy and competence, or experience difficulties from these factors other than in interpersonal relationships, remains largely unexplored. This study examined the influence of rejection sensitivity and need satisfaction (autonomy, competence, and relatedness) on learning strategy and self-efficacy. We found that competence satisfaction mediates the relationship between rejection sensitivity and self-efficacy. In addition, hierarchical regression analysis revealed a significant three-way interaction of rejection sensitivity, autonomy, and competence satisfaction with learning strategy. Competence satisfaction has a positive effect when individuals have low rejection sensitivity and are satisfied with autonomy need, whereas autonomy satisfaction has a positive effect when individuals have high rejection sensitivity and are dissatisfied with their competence levels. This suggests that autonomy and competence satisfaction levels are important for the understanding of psychological difficulties in rejection sensitive individuals.

Abstract: The X-ray observation of AM Her in a very low state was performed with {\it Suzaku} in October 2008. One flare event with a time scale of $\sim$ 3700 sec was detected at the X-ray luminosity of $6.0 \times 10^{29} {\rm ~erg ~sec}^{-1}$ in the 0.5 -- 10 keV band assuming at a distance of 91 pc. The X-ray spectrum is represented by a thermal plasma emission model with a temperature of $8.67_{-1.14}^{+1.31}$ keV. During the quiescence out of the flare interval, {\it Suzaku} also detected significant X-rays at a luminosity of $1.7 \times 10^{29} {\rm ~erg ~sec}^{-1}$ in the 0.5 -- 10 keV band, showing a clear spin modulation at a period of 0.1289273(2) days at BJD 2454771.581. The X-ray spectra in the quiescence were represented by a MEKAL + Power Law (PL) model or a single CEMEKL model, which are also supported by phase-resolved analyses. A correlation between the temperature and the volume emission measure was found together with historical X-ray measurements of AM Her in various states. In order to account for a possible non-thermal emission from AM Her, particle acceleration mechanisms in the AM Her system are also discussed, including a new proposal of a shock acceleration process on the top of the accretion column.

Abstract: A new pulsating X-ray source, AX J183220-0840, with a 1549.1-s period was discovered at R.A.= 18h32m20s and Dec.=-8d40'30'' (J2000, uncertainty=0.6degree) during an ASCA observation on the Galactic plane. The source was observed two times, in 1997 and in 1999. A phase-averaged X-ray flux of 1.1E-11 ergs cm-2 s-1 and pulsation period of 1549.1+/-0.4 s were consistently obtained from these two observations. The X-ray spectrum was represented by a flat absorbed power-law with a photon-index of =~0.8 and an absorption column density of =~1.3E22 cm-2. Also, a signature of iron K-shell line emission with a centroid of 6.7 keV and an equivalent width of approximately 450 eV was detected. From the pulsation period and the iron-line feature, AX J183220-0840 is likely to be a magnetic white dwarf binary with a complexly absorbed thermal spectrum with a temperature of about 10 keV.

Abstract: Manufacturing electronic devices by printing techniques with low temperature sintering of nano-size material particles can revolutionize the electronics industry in coming years. The impact of this change to the industry can be significant enabling low-cost products and flexibility in manufacturing. implementation of a new production technology with new materials requires thorough elementary knowledge creation. It should be noticed that although some of first electronic devices ideally can be manufactured by printing, at the present several modules are in fact manufactured by using hybrid techniques (for instance photolithography, vapor depositions, spraying, etc...).

Physics , 2014,
Abstract: HESS J1507-622 is one of the bright unidentified TeV objects. HESS J1507-622 is unique, since the location of the object is off the Galactic disk. We observed the HESS J1507-622 region with the Suzaku XIS, and found no obvious counterpart although there is no severe interstellar extinction. However, there are two interesting X-ray objects; SRC1 is a bright extended source, and SRC2 is a faint diffuse object. If either of them is a counterpart, the flux ratio between TeV and X-ray is large, and HESS J1507-622 is a real dark particle accelerator.

Abstract: A transbronchial lung biopsy (TBLB) showed a moderate infiltration of lymphocytes in the alveolar septae. He was diagnosed as interstitial pneumonia, and treated by drugs. One year later, his condition deteriolated, and a large open biopsy was performed. It showed a diffuse severe infiltration of lymphocytes in the alveolar walls and a few epithelioid granulomas. No bronchiolitis was seen.Immunohistochemical study denied lymphocyte monoclonality, and he was diagnosed as lymphocytic interstitial pneumonia (LIP). He was treated by steroid.Six months later, TBLB showed peribronchial lymphocyte infiltration. A large open biopsy also revealed a severe lymphocytic infiltration around the bronchioles, sparing alveolar wall lymphocytic infiltration. Immunohistochemical study denied malignant lymphoma. He was diagnosed as follicular bronchiolitis (FB). One year later, TBLB showed little lymphocytic infiltration in the alveolar walls as well as peribronchial walls. Two years later, his condition became worse, and TBLB showed features of LIP. Later, his condition was stationary for 6 years with mild lung opacities for 6 years. These findings show that LIP and FB are interchangeable and overlapping, and suggest that LIP and FB belong to the same spectrum of benign lymphoproliferative disorders of the lungs.Follicular bronchiolitis (FB) is a benign lymphoproliferative lung disease characterized by hyperplastic mucosa-associated lymphoid tissue present around the peribronchial spaces [1]. Patients with FB are often associated with collagen vasculitis diseases, immunodeficiency state, hyperimmune state, and hereditary factors. Idiopathic FB is rare. Lymphocytic interstitial pneumonia (LIP) is also a benign lymphoproliferative lung disease characterized by severe lymphocytic infiltration of the alveolar septae [1]. Patients with LIP are also often associated with collagen vascular diseases, immunological diseases, immunodeficiency diseases, lung infections, and drug induced disease

Abstract: The virtual slide(s) for this article can be found here:http://www.diagnosticpathology.diagnomx.eu/vs/1541653085652296 webciteMalignant lymphoma of the lung is very rare [1]. Although any types of malignant lymphomas can occur in the lung, approximately 70-90% of the pulmonary lymphoma is marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT) of the lung [1]. Pulmonary lymphomas accounted for only 0.5% of all pulmonary neoplasms [1]. Patients with marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT) (abbreviated hereafter as MALT lymphoma) of the lung tend to be in their fifth, sixth, or seventh decades, with a slight male preponderance [1]. Etiologically, pulmonary MALT lymphoma is thought to arise in acquired MALT secondary to inflammatory or autoimmune process. The prognosis of pulmonary MALT lymphoma is relatively good when surgical resection is possible, while it may be worse in surgically-unresectable cases [1]. The 5-year survival of pulmonary MALT lymphoma is 84-94% [1]. Pulmonary MALT lymphoma progresses into diffuse large B-cell lymphoma in a small percentage, as is the case with MALT lymphoma of other organs. Other relatively common lymphomas and related diseases of the lung are diffuse large B-cell lymphoma, lymphomatoid granulomatosis, and Langerhans cell histiocytosis [1]. Histopathologically, pulmonary MALT lymphoma is an extranodal marginal zone lymphoma comprising morphologically of heterogeneous small B-cells, monocytoid cells, small lymphocytes, and scattered immunoblasts-like and centroblasts-like cells. There is a plasma cell differentiation in a proportion of cases. The neoplastic cells typically infiltrate into the bronchial mucosal epithelial cells, creating lymphoepithelial lesions [1].Most of MALT lymphoma is negative for CD5 [2]. However, there are a few reports of CD5-positive MALT lymphoma of the lung and other organs [3-13]. The CD5 positivity in MALT lymphoma made the diagnosis difficult,
