Guest editors'' commentary: Japanese socialization research in review

This focus section has presented Japanese research on a variety of socialization agents and contexts, including mothering, fathering, peers and multiple-caretakers in families and institutions. The reader is encouraged to compare the papers, discover the theoretical and applied implications of each study for child development in the reader's own culture, and to pursue collaborations with the outstanding young Japanese contributors. We conclude with brief comments on each of the five articles, discussing their limitations, most significant findings, theoretical importance, and implications for subsequent research.     

Compositional Z: Confluence Proofs for Permutative Conversion

This paper gives new confluence proofs for several lambda calculi with permutation-like reduction, including lambda calculi corresponding to intuitionistic and classical natural deduction with disjunction and permutative conversions, and a lambda calculus with explicit substitutions. For lambda calculi with permutative conversion, naïve parallel reduction technique does not work, and (if we consider untyped terms, and hence we do not use strong normalization) traditional notion of residuals is required as Ando pointed out. This paper shows that the difficulties can be avoided by extending the technique proposed by Dehornoy and van Oostrom, called the Z theorem: existence of a mapping on terms with the Z property concludes the confluence. Since it is still hard to directly define a mapping with the Z property for the lambda calculi with permutative conversions, this paper extends the Z theorem to compositional functions, called compositional Z, and shows that we can adopt it to the calculi.     

Judgment of infant cry: The roles of acoustic characteristics and sociodemographic characteristics

Adult judgments of infant cry are determined by both acoustic properties of the cry and listener sociodemographic characteristics. The main purpose of this research was to investigate how these two sources shape adult judgments of infant cry. We systematically manipulated both the acoustic properties of infant cries and contrasted listener sociodemographic characteristics. Then, we asked participants to listen to several acoustic manipulations of infant cries and to judge the level of distress the infant was expressing and the level of distress participants felt when listening. Finally, as a contrasting condition, participants estimated the age of the crying infant. Using tree‐based models, we found that judgments of the level of distress the infant was expressing as well as the level of distress listeners felt are mainly accounted for by select acoustic properties of infant cry (proportion of sound/pause, fundamental frequency, and number of utterances), whereas age estimates of a crying infant are determined mainly by listener sociodemographic characteristics (gender and parental status). Implications for understanding infant cry and its effects as well as early caregiver‐infant interactions are discussed.

Asymmetrical neural adaptation in lower leg muscles as a consequence of stereotypical motor training

Despite well-authorized facts regarding asymmetrical architectural changes between different limbs after persistent participation in particular motor training, no studies have addressed the neural aspects to the present. The authors undertook the study to elucidate the possibility of neural adaptation on a limb-by-limb basis after repetitive engagement in a particular motor training routine. We investigated lower leg muscles in endurance-trained track runners who have been trained by routinely running on a track in counterclockwise direction on curved paths. Stretch reflex responses in the plantarflexor muscles (soleus [SOL], medial [MG], and lateral head of the gastrocnemius muscle) were evaluated bilaterally with participants sitting at rest. Comparisons were made between homonymous muscles of the right (corresponding to outside leg for track running) and left leg (inside leg, likewise) and with a group of nontrained controls. The result clearly demonstrated that the responses were prominently different between the legs (thus, asymmetrical) in the MG muscles and partially in the SOL muscles in the trained group. In contrast, no such differences were obtained in the nontrained control group. The result demonstrated that neural adaptation took place asymmetrically and that could be attributable to their repetitive engagement in the stereotypical motor task.     

Referred sensations induced by a mirror box in healthy subjects

Twenty-one healthy subjects were instructed to observe the mirror image of the tactile stimulation of their own hand (control condition) or an assistant’s hand (experimental condition) while being queried about the referred sensation (RS) in their own masked hand behind the mirror. The rated intensity of the RS under the experimental condition was significantly stronger than that under the control condition. In a second experiment, the experimental condition was replaced with the tactile stimulation of a prosthetic (rubber) hand, and was compared with the tactile stimulation of the subject’s own hand (control condition). In both of the experiments, the rated intensity of RS was significantly stronger under the experimental condition than under the control condition. The qualitative characteristics of the induced RS on the mirror image hand—including the location, sense of ownership, and various subjective feelings—were also found to vary among subjects. In conclusion, an RS could be induced in healthy subjects on the mirror image of the hand by tactile stimulations, although this effect differed substantially among individuals.     

Force Control of Ankle Dorsiflexors in Young Adults: Effects of Bilateral Control and Leg Dominance

Abstract

We investigated whether bilateral lower-limb control and leg dominance affect force control ability in 15 healthy young adults (9 males and 6 females, age =26.8?±?4.1 years). Participants performed isometric ankle dorsiflexion force control tasks, matching a visual target (10% of maximal effort) as quickly and precisely as possible in ballistic and tonic tasks. Performance was evaluated using force error, force steadiness, amount of muscle activity of the tibialis anterior, and response time characteristics. Results showed no significant effects of leg dominance during both ballistic and tonic tasks, while bilateral condition resulted in significantly larger error, less force steadiness, compared to unilateral condition, and only during the tonic task. Consequently, bilateral control, specifically in tasks utilizing feedback control (i.e., tonic task) might affect force control ability, possibly because of the interhemispheric inhibition to meet bilateral task complexity and integrate afferent bilateral sensory information from both right and left legs.     

Rebuilding a Confessional State: Islamic Ecclesiology in Turkey,Russia and China

Abstract

Religions are playing an ever more prominent role in the public sphere in the world today, and it hardly seems productive to examine religion–state relations from the traditional liberal standpoint of idealising the state's non-intervention in religious matters. In this article we examine the relations between Islam and the state in Turkey, Russia/the Soviet Union and China, using the concept of the ‘confessional state’. A confessional state tries to use not only its dominant religion but also minority religions of all kinds to mobilise wider groups of the population. In confessional states the relations between the state and bodies of clergy are federative, not master-subordinate. The core of the Ottoman confessional state was the millet system, while the ?eyhülislam managed the Muslim majority. The Russian Empire copied the ?eyhülislam and created the Muftiate. Neither the Qing Empire nor the Republic of China built a nationwide system of Muslim administration, so the People's Republic of China architected it from scratch, on the basis of its own communist idea of the ‘united front’. These confessional states were seriously damaged by Atatürk's secularism in Turkey, communist atheism in the Soviet Union and the Great Leap Forward and the Cultural Revolution in China. Later, leaders of these countries realised that secularism and communism could not monopolise the spiritual market of faith, and desperately needed to mobilise the nation, even with the help of traditional religion. They did not try to reintroduce confessional states on the lines of those which had historically existed, but tried to use religious congregations to mobilise the wider strata of the population. In this attempt, the three countries faced different challenges: Turkey suffers from the confessional homogeneity of the state; postcommunist Russia lacks a nationwide Muslim administration; and in China the Muslims do not have an autonomous clerical hierarchy.     

Faith or Tradition: the Armenian Apostolic Church and Community-Building in Armenia and Nagorny Karabakh 1

It is no secret that the Armenian Apostolic Church (AAC) is closely connected with Armenian nationality and Armenian states (Armenia and Nagorny Karabakh). Previous studies have concentrated on surveying the privileges granted to it by these Armenian states. This study goes further by elucidating complementary relations between the AAC and these states in community-building. These states are suffering from the incompetence of local governments created by radical municipal reforms and the decollectivisation of agriculture during the 1990s. They need the help of the AAC, which is potentially able to mobilise rural intellectuals via church (parish) councils. The AAC wishes to reinforce its position, which it sees as endangered by various ‘sectarian’ challenges. Its weak appeal to faith (insufficient evangelisation) gives Protestant ‘sectarians’ abundant room for proselytism, against which the AAC intends to struggle ‘from below’ by its deeper involvement in community-building.
