The ecohealth system and the community engagement movement in foundations: A case study of mutual benefits from grants funded by the United Nations Foundation
Authors: Yacoob May , Hetzler Beth , Langer Rafael 
Published: June 2004

Abstract Ecohealth is a process for identifying key environmental determinants causing mortality or morbidity and combating them by mobilizing multiple social sectors. Evolving out of the concept of environmental health, ecohealth provides a framework for long‐term sustainability. The health outcomes anticipated by environmental interventions are part of a long‐term agenda and require fundamental groundwork for the growth of community‐driven development. Building long‐term sustainability requires that two key approaches be developed through ecohealth. The first is the strengthening of local community institutions, whether formal or informal. The second is building financial mechanisms that are more diversified and less reliant on a single donor. As a result, the ecohealth system provides an opportunity for foundations to empower communities, build cross‐cutting cooperation, and gain knowledge through projects. If people's environmental behaviour is to change and be sustained in the long term to produce desired health outcomes, this will require all members of society to be capable of functioning within the existing institutional infrastructure. This means that not only do formal institutions need to become more accessible but also that concepts relating to local informal institutions must be incorporated into ecohealth projects. It is imperative that we identify and understand relevant local institutions and how they can be transformed so that new environmental forms of behaviour can be sustained and result in positive health outcomes. The intersection of environmental and health concerns provides an ideal area in which the gap between government and civil society can be bridged — not only providing solutions to ecohealth concerns, but building government capacity in general and making these positive changes sustainable in the long term. This article is a case study, based on several United Nations Foundation grants. It outlines the significance of traditional community organizations, the breadth of their long‐term relations with communities, their resources, and the adoption of sustained forms of behaviour. In addition, the article highlights the role that international foundations can play in creating innovative financing mechanisms through community‐based foundations.
Determining the optimal tax on mining
Authors: Tilton John E. 
Published: June 2004

Abstract This article examines three arguments often raised in support of higher taxes on mining and finds them wanting: First, the wealth or economic rents associated with particularly rich deposits rightfully belong to the citizens of the host country. Second, mining companies should compensate the State and the public for their use of mineral resources, given the intrinsic value arising from their non‐renewable nature. Third, the division of the wealth created by mining is unfair. Too much goes to mining companies, and too little to the host country to promote economic development. It suggests instead that host governments should maximize the net present value of the social benefits flowing from their mineral sector. In practice, unfortunately, it is often difficult to know whether this objective is served by raising or lowering the level of taxation on mining.
Enhanced water resource base for sustainable integrated water resource management
Authors: Boutkan Else , Stikker Allerd 
Published: June 2004

Abstract The article states the case for greatly enhanced reliance on desalination in the provision of freshwater. It argues that the concept of integrated water resource management (IWRM), should be expanded to routinely include desalination, and that sea water and brackish water should be listed among available sources of freshwater. In recent years, the price per m3 of freshwater obtained from desalination has steadily declined, and is now within competitive range of conventional sources, especially as extracting water from surface sources (rivers, lakes) is becoming increasingly expensive as well as ecologically harmful, and groundwater in many locations is saline or depleted. With the expectation that by 2020, five billion people will reside in megacities, today's conventional water resources are likely to become insufficient. As many of these megacities are located near ocean coasts, sea water seems a logical solution.
Mitochondrial DNA analysis of the introduced fall webworm, showing its shift in life cycle in Japan
Authors: GOMI Tadashi , MURAJI Masahiko , TAKEDA Makio 
Published: June 2004

AbstractThe fall webworm, Hyphantria cunea (Drury) (Lepidoptera: Arctiidae), was introduced from North America into Japan in 1945. For the first three decades after its introduction, its life cycle was bivoltine. Thereafter, its life cycle shifted to trivoltine in south‐western areas of Japan. Two hypotheses have been proposed for the process that led to the shift in voltinism: one based on a single and the other on multiple independent colonizations. To test these hypotheses, mitochondrial (mt)DNA sequences were analyzed in the black‐headed type of 14 Japanese, one Korean and two North American populations of H. cunea. In addition, the same regions of mtDNA were compared with the red‐headed type of two North American populations. In the black‐headed type, mtDNA sequences were the same in all Japanese populations and in the Korean population, but sequences of the North American populations differed from each other and from those of the other populations. These results suggest that the process of the shift in voltinism occurred originally in Japan, and that the Japanese and the Korean population of H. cunea originated from a relatively small area in North America.
Systematic study of the genusCyphononyx(Hymenoptera: Pompilidae) occurring in Japan
Authors: SHIMIZU Akira , WAHIS Raymond 
Published: June 2004

AbstractGeneric characteristics and phylogenetic relationships of the genusCyphononyxare presented, together with a brief review of the biology of the genus. It is shown that only one species of the genus,C. fulvognathus(Rohwer), occurs in Japan. This species is distributed also in Taiwan and south China, and has hitherto been recognized under the name ofC. dorsalis. In addition, two new combinations are presented:Cyphononyx hirtus(Haupt, 1935) (= Cryptochilus hirtusHaupt) andCyphononyx plebejus(de Saussure, 1867) (= Agenia plebejade Saussure), both of which were recorded from the Oriental Region.
Species composition and life histories of shelter‐building caterpillars on Salix miyabeana
Authors: NAKAMURA Masahiro , OHGUSHI Takayuki 
Published: June 2004

AbstractWe studied the species composition and life history patterns of shelter‐building microlepidoptera on the willow Salix miyabeana in Hokkaido, northern Japan. We identified 23 microlepidopteran species across seven families that constructed leaf shelters. Species in Tortricidae and Pyralidae comprised approximately 90% of the total number of sampled shelter‐building microlepidoptera that reached adult eclosion in the laboratory. Seasonal changes in the density of leaf shelters showed two peaks: early June and mid‐August. In June, caterpillars of Gypsonoma bifasciata, Gypsonoma ephoropa, Acleris issikii and Saliciphage acharis were the principal shelter builders, while in August shelters were constructed primarily by caterpillars of Nephopterix adelphella, A. issikii and S. acharis. Approximately 90% of leaf shelters were constructed on the top portions of shoots, suggesting that most shelter‐building caterpillars prefer to build leaf shelters here.
Role of extrafloral nectaries of Vicia faba in attraction of ants and herbivore exclusion by ants
Authors: KATAYAMA Noboru , SUZUKI Nobuhiko 
Published: June 2004

AbstractWe directly evaluated the role of extrafloral nectaries (EFN) in ant attraction and herbivore exclusion by experimental removal of EFN in the laboratory. When EFN of Vicia faba Linnaeus (Leguminosae) were artificially removed, the number of workers of Tetramorium tsushimae Emery (Hymenoptera: Formicidae) visiting the plant decreased, and the efficiency of herbivore exclusion by ants also decreased. Herbivore exclusion by ants was mostly ineffective on a plant when less than four workers visited the plant, but when more than four workers visited, the time a herbivore resided on the plant decreased rapidly with increasing numbers of visiting ants. Therefore, the efficiency of herbivore exclusion from a plant is determined by the number of ants visiting, and EFN play an important role in ant attraction.
Food plants and life cycle of Lymantria bantaizana Matsumura (Lepidoptera: Lymantriidae) in northern Honshu, Japan
Authors: GOTOH Tadao , SCHAEFER Paul W. , DOI Nobuo 
Published: June 2004

AbstractThe food plants and life cycle of Lymantria bantaizana were investigated in Iwate Prefecture, northern Honshu, Japan from 2000 to 2002. Eggs laid in July hatched approximately 10 days after oviposition. Hatched larvae fed only on Juglandaceae, Juglans mandshurica var. sachaliensis, J. regia var. orientalis and Pterocarya rhoifolia when reared in the laboratory. In field rearing, the plants of Juglans enabled the moth to complete its life cycle. Differing from all other known Lymantria species in Japan, the moth overwintered not in the egg stage but in the fifth or sixth instar larval stage. Lymantria bantaizana had eight larval instars in both sexes. Moth emergence occurred mostly in July at a field‐trapping site in Iwate Prefecture.
Oviposition site of and gall formation by the fruit gall midge Asphondylia aucubae (Diptera: Cecidomyiidae) in relation to internal fruit structure
Authors: IMAI Kensuke , OHSAKI Naota 
Published: June 2004

AbstractMost gall insects use young developing plant organs for gall formation; however, little information is available on the histological identification of such tissues or the changes in their availability with plant growth. We investigated the oviposition site of and the tissue used for gall formation by the midge Asphondylia aucubae Yukawa and Ohsaki, which is responsible for galls on the fruit of Aucuba japonica Thunb., by comparing the internal structures of young developing fruit, mature intact (uninfested) fruit, and galled fruit. The midge deposited eggs between the integument and the carpel of young fruit. Larval chambers were made of callus‐like tissue and were formed between the embryo sac and the carpel, where the integument was initially situated. The integument and part of the carpel were thus identified as critical plant tissues used by A. aucubae in forming galls. The integument degenerates in mature intact fruit; therefore, the season of emergence and oviposition by the midge may be determined by the timing of integument degeneration.

Published: June 2004

AbstractTo understand the developmental process of aphid soldier differentiation, we investigated the morphological characters of normal nymphs, soldier nymphs and developing embryos of Pseudoregma bambucicola. Results of morphometric analyses showed that normal and soldier nymphs formed discrete clusters on the basis of several morphological characters, although a small number of intermediate individuals, termed ‘intercaste nymphs’, were present. In late embryonic stages, normal and soldier embryos were morphologically distinguishable. The earlier the embryonic stage, the smaller the morphological differences between them. In early embryos less than 1000 µm in length, normal and soldier embryos were not morphologically distinguishable, suggesting that the onset of soldier differentiation occurs at an early embryonic stage. Throughout embryonic development, morphological differentiation of the soldier caste proceeded gradually. Notably, several morphological characters of soldiers grew remarkably upon larviposition. Observation of embryonic leg cuticle revealed a characteristic folding structure, indicating that  some  morphological  traits  of  the  soldier  are  exaggerated  upon  larviposition  through  expansion  of the folded cuticle. We suggest that morphological differentiation of the soldier caste in P. bambucicola comprises two phases: gradual growth during embryogenesis and rapid growth upon larviposition.

Published: June 2004

AbstractBackground:  Elevated plasma homocysteine levels are known as a risk for atherosclerotic vascular disease and venous thrombosis and have been shown as a risk for late‐onset Alzheimer's disease (LOAD).Method:  To examine the effect of genetic factors predisposing to elevated plasma homocysteine levels on the occurrence of LOAD, we determined the genotype of a C677T polymorphism of methylenetetrahydrofolate reductase (MTHFR) gene and a variable number tandem repeat (VNTR) spanning exon 13–intron 13 boundary of cystathionine β‐synthase (CBS) gene in patients with LOAD and community‐based control subjects.Results:  Logistic regression indicated that the MTHFR‐T allele was a risk for LOAD (P < 0.05), independently from apolipoprotein E‐ɛ4 (APOE‐ɛ4) allele. Kaplan–Meier tests showed that in APOE‐ɛ4 non‐carriers, individuals with the MTHFR‐TT genotype have occurences of LOAD earlier than those with the MTHFR‐CC genotype (P < 0.05). Multiple regression analysis indicates that MTHFR‐T allele increases plasma homocysteine levels (P = 0.0002), while the number of X chromosomes decreases (P = 0.01). Plasma homocysteine level was not correlated with age, plasma albumin reflecting nutritional condition, and the dose of APOE‐ɛ4 allele. The CBS‐20 VNTR allele showed the same trend to increase plasma homocysteine level as the MTHFR‐T allele, but a risk effect for LOAD was not evident.Conclusion:  A genetic propensity for elevated plasma homocysteine levels, explained by the MTHFR‐T allele encoding defective enzymatic function, is involved in the development of LOAD, particularly in APOE‐ɛ4 non‐carriers, and that homocysteine metabolism could be a preventive target to LOAD in the elderly.

Published: June 2004

AbstractBackground:  Advancing age increases the risk of developing dementia. Recent studies have clarified characteristic cognitive changes in very old patients with dementia. Although non‐cognitive symptoms are frequent in dementia, relatively little attention has been paid to the nature of behavioral and psychological symptoms of dementia (BPSD).Methods:  A retrospective review of a database was performed to compare 27 very old patients with Alzheimer's disease (AD) (onset age ≥ 85) with 162 less old patients (onset age < 85). Cognitive decline, ability to carry out activities of daily living (ADL), and overall severity were rated. BPSD were evaluated using a 16‐item questionnaire to the compare frequency of each symptom between old and very old groups.Results:  Cognitive decline was equivocal in both old and very old groups. In contrast, very old patients were more impaired in ADL, and BPSD were more frequent in very old patients. Delusions, irritability, and delusional misidentification syndrome were frequent in both groups, but were more prominent in very old patients. Behavioral abnormalities such as excitement, delirium, reversed diurnal rhythm, and wandering were not prominent in old patients, but were frequent in very old patients.Conclusions:  Very old AD patients presented more frequent BPSD than old AD patients. Troublesome behavioral abnormalities particularly prominent in the older patients might represent a heavy burden for caregivers.
Inverted metamorphic sequence in the Sikkim Himalayas: crystallization history, P–T gradient and implications
Authors: Dasgupta S. , Ganguly J. , Neogi S. 
Published: June 2004

AbstractThe metapelitic rocks of the Sikkim Himalayas show an inverted metamorphic sequence (IMS) of the complete Barrovian zones from chlorite to sillimanite + K‐feldspar, with the higher grade rocks appearing at progressively higher structural levels. Within the IMS, four groups of major planar structures, S1, S2 and S3 were recognised. The S2 structures are pervasive throughout the Barrovian sequence, and are sub‐parallel to the metamorphic isograds. The mineral growth in all zones is dominantly syn‐S2. The disposition of the metamorphic zones and structural features show that the zones were folded as a northerly plunging antiform. Significant bulk compositional variation, with consequent changes of mineralogy, occurs even at the scale of a thin section in some garnet zone rocks. The results of detailed petrographic and thermobarometric studies of the metapelites along a roughly E–W transect show progressive increase of both pressure and temperature with increasing structural levels in the entire IMS. This is contrary to all models that call for thermal inversion as a possible reason for the origin of the IMS. Also, the observation of the temporal relation between crystallization and S2 structures is problematic for models of post‐/late‐metamorphic tectonic inversion by recumbent folding or thrusting. A successful model of the IMS should explain the petrological coherence of the Barrovian zones and the close relationship of crystallization in each zone with S2 planar structures along with the observed trend(s) of P–T variation in Sikkim and in other sections. A discussion is presented of some of the available models that, with some modifications, seem to be capable of explaining these observations.
A new method for the derivation of the closed nets in the phase diagram space of multisystems. I. The absent phase substitution method
Authors: Hu J. , Yin H. , Duan Z. 
Published: June 2004

AbstractA new convenient combinatorial method is developed here to derive the invariant points in multisystem closed nets – the absent phase substitution (APS) method. It substantially simplifies the derivation of the closed nets in multisystems with many components and phases. For the multisystems whose total phase number (NPS) ≤ twice the number of the absent phases (m) in an invariant assemblage, the method can yield regular closed nets with or without globally absent phases; for other multisystems, the method can yield the regular closed nets with globally absent phases. As examples, the APS method was used to predict: (1) the regular closed nets of unary to quinary n + 4‐phase multisystems, unary 6‐phase multisystem and ternary 8‐phase multisystem; (2) the basic properties of the regular closed nets of the quaternary and quinary multisystems with n + 4 and n + 5 phases. Two multisystems were chosen to demonstrate how to select a realistic closed net from the numerous possible closed nets of a complex multisystem, and how to derive a realistic partially closed‐net, closed‐net‐diagram and the related realistic straight‐line‐net‐diagram. Comparisons of our APS method for the derivation of complicated closed nets with other methods indicate that this method is much simpler and more efficient.
Grain coarsening in contact metamorphic carbonates: effects of second‐phase particles, fluid flow and thermal perturbations
Authors: Berger A. , Herwegh M. 
Published: June 2004

AbstractUnder contact metamorphic conditions, carbonate rocks in the direct vicinity of the Adamello pluton reflect a temperature‐induced grain coarsening. Despite this large‐scale trend, a considerable grain size scatter occurs on the outcrop‐scale indicating local influence of second‐order effects such as thermal perturbations, fluid flow and second‐phase particles. Second‐phase particles, whose sizes range from nano‐ to the micron‐scale, induce the most pronounced data scatter resulting in grain sizes too small by up to a factor of 10, compared with theoretical grain growth in a pure system. Such values are restricted to relatively impure samples consisting of up to 10 vol.% micron‐scale second‐phase particles, or to samples containing a large number of nano‐scale particles. The obtained data set suggests that the second phases induce a temperature‐controlled reduction on calcite grain growth. The mean calcite grain size can therefore be expressed in the form D = C2 eQ*/RT(dp/fp)m*, where C2 is a constant, Q* is an activation energy, T the temperature and m* the exponent of the ratio dp/fp, i.e. of the average size of the second phases divided by their volume fraction. However, more data are needed to obtain reliable values for C2 and Q*. Besides variations in the average grain size, the presence of second‐phase particles generates crystal size distribution (CSD) shapes characterized by lognormal distributions, which differ from the Gaussian‐type distributions of the pure samples. In contrast, fluid‐enhanced grain growth does not change the shape of the CSDs, but due to enhanced transport properties, the average grain sizes increase by a factor of 2 and the variance of the distribution increases. Stable δ18O and δ13C isotope ratios in fluid‐affected zones only deviate slightly from the host rock values, suggesting low fluid/rock ratios. Grain growth modelling indicates that the fluid‐induced grain size variations can develop within several ka. As inferred from a combination of thermal and grain growth modelling, dykes with widths of up to 1 m have only a restricted influence on grain size deviations smaller than a factor of 1.1. To summarize, considerable grain size variations of up to one order of magnitude can locally result from second‐order effects. Such effects require special attention when comparing experimentally derived grain growth kinetics with field studies.
