In the present article, we describe what we call Intransparent-Gap Relatives (IGRs) in Japanese. In IGRs, a gap is located within the relative clause, and the head noun appears outside the relative clause. Unlike the standard head-external relatives, the gap in IGRs is not transparently associated with the head noun, but they are mediated through a metonymic relation. We propose a formal account of IGRs in terms of incremental parsing in Dynamic Syntax: an IGR string is processed in a left-to-right manner, and a semantic structure is progressively built up. This account unifies the standard head-external relatives and IGRs, relegating their differences to the ways in which the head noun is parsed and construed against the relative clause structure. Confirmation of this analysis comes from cross-constructional and cross-linguistic considerations. First, the analysis predicts that a metonymic reading is available in relatives but not in other rightward-displacement constructions, such as clefts and postposing. Second, the analysis suggests that IGRs are possible in languages such as Japanese and Korean, where the relative clause is processed before the head noun, but not in languages such as English and French, where the head noun is processed before the relative clause.

The Southeastern Anatolia Project (Güneydoğu Anadolu Projesi, GAP) is arguably the largest regional development project ever witnessed in Turkey. Begun in the 1970s, GAP initially aimed primarily at the construction of 22 dams and 19 hydroelectric power plants on the Tigris and Euphrates rivers and of extensive irrigation networks to produce hydroelectric energy and water 1.8 million hectares of land in southeastern Turkey. Later, the scope of GAP broadened significantly as it became a more ambitious and comprehensive scheme of modernization and transformation. Following this expansion, the multidimensionality of GAP and its multifaceted implications became clearer at both the national and international level. The project grew more visible and influential not only in political and public discourses, but also in the GAP region itself. Despite these developments, however, the question of how the project’s characteristics, vocabulary, rationales, and mechanisms have changed since its inception remains underdiscussed. This article asks what GAP was in the past and what it has more recently become. It examines the gradual transformation of GAP over forty years by specifically taking into account the continuities and ruptures in development discourse, theory, and practice since the 1950s. In this way, the article aims to provide a new perspective regarding the stages through which the project has passed to reach its current form.

Chapter 4 of Dennis Schulting’s book Kant’s Radical Subjectivism targets those commentators who take there to be a gap in the transcendental deduction of the categories, arguing instead that there is no gap between the necessary application of the categories and their exemplification in the object of experience. In these comments on the chapter, I suggest a minimal sense in which the fact that there is a gap is non-negotiable. The interesting question is not whether there is a gap which needs to be bridged, but how and why Kant makes the step from subjectivity to objectivity.

This paper presents the design and development of an X-band microstrip gap-coupled sectoral patch array antenna for application in wireless systems. A novel concept of bandwidth enhancement is considered for gap-coupled sectoral microstrip patch array antenna, which uses one active receiving antenna and multiple parasitic elements with finite ground plane. The parasitic elements give the possibility of creating a directive antenna beam. A broadband of 1 GHz with a return loss of −50 dB has been achieved in X-band along with a directivity of 11.1 dBi and reduced side lobe level to −23.7 for 3 dB angular width.

Soil water potentials were measured weekly by psychrometers at 20 cm depth during the dry season in a tropical moist forest on Barro Colorado Island, Panama. There was a persistent gradient of decreasing soil moisture from gap centre to gap edge to adjacent understorey at both a large and a small gap. On both a north-south and an east-west transect, the soil was drier (water potentials were more negative) on an upland surface than on moderate slopes. This trend was reflected in the predawn, total water potentials of shallow-rooted Psychotria horizontalis and deep-rooted Trichilia tuberculata measured in the understorey during the last two months of the dry season. P. horizontalis from the wettest sites on the transects had higher osmotic potentials at full hydration and at zero turgor, indicating less drought resistance than for conspecifics from the driest sites.

The spatial distribution of canopy gaps was analysed on three sites (total 71 ha) in the tropical moist forest of Tai National Park, Ivory Coast. Pattern analysis revealed a clustered distribution of gaps for two of the three sites. Catena dependent gap formation processes might explain local differences in the occurrence and distribution of gaps. Gap densities, sizes and percentage forest area in gap phase are higher on the upper and middle slope than on the crest or lower slope. As a consequence, regeneration of gap dependent tree species might be directed to the catena positions with the highest disturbance regime. The spatial distribution of gap dependent species can be clumped, not only due to the regeneration within gaps, but also due to the clustered nature of gap distribution on its own.

Suppose that X is an infinite set and I(X) is the symmetric inverse semigroup defined on X. If α∈I(X), we let dom α and ran α denote the domain and range of α, respectively, and we say that g(α)=|X/dom α| and d(α)=|X/ran α| is the ‘gap’ and the ‘defect’ of α, respectively. In this paper, we study algebraic properties of the semigroup . For example, we describe Green’s relations and ideals in A(X), and determine all maximal subsemigroups of A(X) when X is uncountable.

Seedlings of five species in the Dipterocarpaceae were grown in experimental plots in Sabah, Malaysia. These were sited both in gaps and understorey and on alluvial and sandstone soils. Half of all seedlings were provided with a complete fertilizer. Herbivore damage levels were recorded on over 25 000 individual leaves in four surveys over the course of 2 y. Rates of herbivory were lower on mature leaves (0.07–0.8% leaf area mo−1 among species) than new leaves (2.1–4.4% leaf area mo−1). There were no overall effects of light conditions, soil type, fertilizer treatment or time on rates of herbivory. The only consistent source of variation was that between species, with the three alluvial-specialist species suffering higher rates of damage than the two sandstone-specialists. Mature leaves of alluvial species received greater damage in sandstone soils, whereas sandstone species were damaged at equivalent rates on both soil types. New leaves were more damaged on their native soil type. Published herbivory rates vary in the timescales and methods of measurement. Nevertheless, the few comparable studies confirm that herbivory rates on seedlings in tropical rain forests are remarkably constant over time and across experimental treatments.

The frequency with which express saccades are generated under a variety of conditions in rhesus monkeys was examined. Increasing the gap time between fixation spot termination and target onset increased express saccade frequency but was progressively less effective in doing so as the number of target positions in the sample was increased. Express saccades were rarely produced when two targets were presented simultaneously and the choice of either of which was rewarded; a temporal asynchrony of only 17 ms between the targets reinstated express saccade generation. Express saccades continued to be generated when the vergence or pursuit systems was coactivated with the saccadic system.

For a positive recurrent continuous-time Markov chain on a countable state space, we compare the access time to equilibrium to the hitting time of a particular state. For monotone processes, the exponential rates are ranked. When the process starts far from equilibrium, a cutoff phenomenon occurs at the same instant, in the sense that both the access time to equilibrium and the hitting time of a fixed state are equivalent to the expectation of the latter. In the case of Markov chains on trees, that expectation can be computed explicitly. The results are illustrated on the M/M/∞ queue.

In tropical moist forests, length of the dry period may have a profound influence on leaf dynamics, plant growth and survival. To evaluate the role of light and water availability on seedling performance, a 1-y experiment was carried out in a tropical moist forest in the Bolivian Amazon in which seedlings of three tree species (Brosimum lactescens, Cedrela odorata and Schizolobium amazonicum) were planted in gaps and the understorey. Variation in length of the dry period was simulated by subjecting part of the seedlings to a water treatment at the end of the dry period. Gaps and understorey had a similar soil moisture content, which varied between 39% in the wet season and 16% in the dry season. Height and leaf growth rates were higher in gap compared to understorey plants, and in the wet compared to the dry season. A high growth during the wet season provided gap plants with a decisive size advantage over understorey plants during the dry season. Their larger root system allowed gap plants to explore a larger surface area and deeper soil layers for water. Consequently, gap plants of Cedrela experienced a shorter deciduous period (22 d) compared to understorey plants (61 d). Watering at the end of the dry season cued the flushing of new leaves by Cedrela, although it did not lead to a higher plant growth.

Nests of leaf-cutting ants (Hymenoptera: Formicidae: Attini) are abundant disturbances in Neotropical rain forests, and could affect the plant community both while the nests are active and after they are abandoned. We measured the diversity and abundance of understorey plants (>1 m in height) in the area around active and abandoned nests of leaf-cutting ants (Atta cephalotes) at the La Selva Biological Station in Costa Rica. Sampel quadrats on active nests had reduced diversity (number of morphospecies) and abundance of both small (height >10 cm) and large (10 cm–1 m) understorey plants, when compared to the nearby forest floor (3 and 13 m from the nest edge). Abandoned nests had greater diversity and marginally greater abundance of small understorey plants relative to nearby forest; there was no difference in diversity or abundance of large understorey plants. Leaf-cutting ant nests create gaps in the plant understorey when active, but serve as centres of recruitment for small plants after they are abandoned. Thus, like canopy gaps, ant nests could play an important role in recruitment of new individuals and maintenance of plant species diversity in tropical forests.

The maturation of female Schistosoma mansoni depends on pairing with a male which induces mitotic activities in the reproductive organs of the female worm. Since in other organisms cell proliferation is regulated by well-conserved signal transducing molecules, we looked for such molecules on immunoblots of schistosomes, using antibodies against conserved epitopes of Ras, GAP and MAP kinases. We identified all 3 molecules in schistosomes and found that they are developmentally regulated. Furthermore, there is evidence for their involvement in the male-directed maturation of the female.

The geometric notions of a gap and gap points between “concentric” spheres in a normed linear space are introduced and studied. The existence of gap points characterizes finitedimensional spaces. General conditions are given under which an infinite-dimensional normed linear space admits concentric spheres such that both these spheres and their dual spheres fail to have gap points.
