    For decades, the central issues surrounding Binding have been investigation of mechanisms of co-referentiality. Most of literature have attempt to find out the mechanisms of binding condition (Chomsky 1981, 1986). This paper will shed new light on the Binding, that is morphological aspects of reflexive anaphors and pronouns, and the source of subject orientation. The purposes of this paper are to claim that Apparent ses (Pica (1985)) in some languages are in fact pronoun and thesubject orientation is emerged as a result of person/gender-feature (φ-feature) impoverishment (cf. Noyer (1997), Halle (1997)). To claim these, this paper looks at Thai and Japanese data. The organization of this paper from next chapter is as follows. Section 2 briefly reviews binding theory we adopt. Then section 3, Thai binding data are introduced. Based on Thai data provided in section 3, section 4 provides proposal and analysis, in which the morpho-semantic framework by Middleton (2018) is introduced. Section 5 shows the current account is also applicable to Japanese reflexives. Section 6 concludes this paper

    This paper aims to propose an account of the scope between negation and VP-coordination in Japanese. We investigate a scope puzzle between negation and VP-coordination, which has been unexplained. We claim that VP-coordination and negation have three readings: (i) Suspended Affixation Reading (neg \u3e VP1 \u3e VP2); (ii) non-Suspended Affixation Reading (VP1 \u3e neg \u3e VP2); and (iii) the third reading (VP2 \u3e neg \u3e VP1), which has been unnoticed. This reading is yielded via the phase-based interpretation system, as well as De Morgan’s Law, which only applies to negation

    Tissue damage in the canine normal esophagus by photoactivation with talaporfin sodium (laserphyrin): a preclinical study.

    [Background] Treatment failure at the primary site after chemoradiotherapy is a major problem in achieving a complete response. Photodynamic therapy (PDT) with porfimer sodium (Photofrin®) has some problems such as the requirement for shielding from light for several weeks and a high incidence of skin phototoxicity. PDT with talaporfin sodium (Laserphyrin) is less toxic and is expected to have a better effect compared with Photofrin PDT. However, Laserphyrin PDT is not approved for use in the esophagus. In this preclinical study, we investigated tissue damage of the canine normal esophagus caused by photoactivation with Laserphyrin. [Methodology/Principal Findings] Diode laser irradiation was performed at 60 min after administration. An area 5 cm oral to the esophagogastric junction was irradiated at 25 J/cm2, 50 J/cm2, and 100 J/cm2 using a three-step escalation. The irradiated areas were evaluated endoscopically on postirradiation days 1 and 7, and were subjected to histological examination after autopsy. The areas injured by photoactivation were 52 mm2, 498 mm2, and 831 mm2 after irradiation at 25 J/cm2, 50 J/cm2, and 100 J/cm2, respectively. Tissue injury was observed in the muscle layer or even deeper at any irradiation level and became more severe as the irradiation dose increased. At 100 J/cm2 both inflammatory changes and necrosis were seen histologically in extra-adventitial tissue. [Conclusions/Significance]To minimize injury of the normal esophagus by photoactivation with Laserphyrin, diode laser irradiation at 25 J/cm2 appears to be safe. For human application, it would be desirable to investigate the optimal laser dose starting from this level

    CO Multi-line Imaging of Nearby Galaxies (COMING). III. Dynamical effect on molecular gas density and star formation in the barred spiral galaxy NGC 4303

    We present the results of 12^{12}CO(JJ=1-0) and 13^{13}CO(JJ=1-0) simultaneous mappings toward the nearby barred spiral galaxy NGC 4303 as a part of the CO Multi-line Imaging of Nearby Galaxies (COMING) project. Barred spiral galaxies often show lower star-formation efficiency (SFE) in their bar region compared to the spiral arms. In this paper, we examine the relation between the SFEs and the volume densities of molecular gas n(H2)n(\rm{H}_2) in the eight different regions within the galactic disk with CO data combined with archival far-ultraviolet and 24 μ\mum data. We confirmed that SFE in the bar region is lower by 39% than that in the spiral arms. Moreover, velocity-alignment stacking analysis was performed for the spectra in the individual regions. The integrated intensity ratios of 12^{12}CO to 13^{13}CO (R12/13R_{12/13}) range from 10 to 17 as the results of stacking. Fixing a kinetic temperature of molecular gas, n(H2)n(\rm{H}_2) was derived from R12/13R_{12/13} via non-local thermodynamic equilibrium (non-LTE) analysis. The density n(H2)n(\rm{H}_2) in the bar is lower by 31-37% than that in the arms and there is a rather tight positive correlation between SFEs and n(H2)n(\rm{H}_2), with a correlation coefficient of 0.8\sim 0.8. Furthermore, we found a dependence of n(H2)n(\rm{H}_2) on the velocity dispersion of inter-molecular clouds (ΔV/sini\Delta V/ \sin i). Specifically, n(H2)n(\rm{H}_2) increases as ΔV/sini\Delta V/ \sin i increases when ΔV/sini<100\Delta V/ \sin i < 100 km s1^{-1}. On the other hand, n(H2)n(\rm{H}_2) decreases as ΔV/sini\Delta V/ \sin i increases when ΔV/sini>100\Delta V/ \sin i > 100 km s1^{-1}. These relations indicate that the variations of SFE could be caused by the volume densities of molecular gas, and the volume densities could be governed by the dynamical influence such as cloud-cloud collisions, shear and enhanced inner-cloud turbulence.Comment: 15 pages, 8 figures, accepted for publication in PAS

    Daytime nap and nighttime breastfeeding are associated with toddlers\u27 nighttime sleep

    The purpose of the present study is to examine the association between toddlers\u27 sleep arrangements and their nighttime sleep duration and other sleep variables. For this investigation, we performed a study in which child activity and sleep levels were recorded using actigraphy. The parents of 1.5-year-old toddlers (n = 106) were asked to attach an actigraphy unit to their child’s waist with an adjustable elastic belt and complete a sleep diary for 7 consecutive days. Questionnaires were used to assess the sleep arrangements of the toddlers. There was a significant negative correlation between nap duration and nighttime sleep duration, suggesting that longer nap sleep induces shorter nighttime sleep duration. Among the sleep arrangements, such as nighttime breastfeeding or co-sleeping, only nighttime breastfeeding predicted shorter nighttime sleep duration. Our findings indicate that shorter naps induce a longer nighttime sleep in 1.5-year-old toddlers while nighttime breastfeeding decreases their nighttime sleep duration

    Sleep maturation influences cognitive development of preterm toddlers

    Our recent study on full-term toddlers demonstrated that daytime nap properties affect the distribution ratio between nap and nighttime sleep duration in total sleep time but does not affect the overall total amount of daily sleep time. However, there is still no clear scientific consensus as to whether the ratio between naps and nighttime sleep or just daily total sleep duration itself is more important for healthy child development. In the current study, to gain an answer to this question, we examined the relationship between the sleep properties and the cognitive development of toddlers born prematurely using actigraphy and the Kyoto scale of psychological development (KSPD) test. 101 premature toddlers of approximately 1.5 years of age were recruited for the study. Actigraphy units were attached to their waist with an adjustable elastic belt for 7 consecutive days and a child sleep diary was completed by their parents. In the study, we found no significant correlation between either nap or nighttime sleep duration and cognitive development of the preterm toddlers. In contrast, we found that stable daily wake time was significantly associated with better cognitive development, suggesting that sleep regulation may contribute to the brain maturation of preterm toddlers

    Preterm toddlers have low nighttime sleep quality and high daytime activity.

    A number of studies have been made on the sleep characteristics of children born preterm in an attempt to develop methods to address the sleep problems commonly observed among such children. However, the reported sleep characteristics from these studies vary depending on the observation methods used, i.e., actigraphy, polysomnography and questionnaire. In the current study, to obtain reliable data on the sleep characteristics of preterm-born children, we investigated the difference in sleep properties between 97 preterm and 97 term toddlers of approximately 1.5 years of age using actigraphy. Actigraphy units were attached to the toddlers’ waists with an adjustable elastic belt for 7 consecutive days, and a child sleep diary was completed by their parents. In the study, we found that preterm toddlers had more nocturnal awakenings and more daytime activity, suggesting that preterm-born children may have a different process of sleep development in their early development
