Public transport service quality and sustainable development: a community stakeholder perspective
Authors: Too Linda , Earl George 
Published: May 2009

AbstractA key element in achieving sustainability's triple‐bottom‐line goals is a good public transport system. Many studies have shown the relationship between effective public transport services and sustainable development at the city level. The purpose of this study is to introduce and use a SERVQUAL framework to measure public transport services within a master‐planned community in Australia. The stakeholder survey findings suggest a wide gap between community expectations of public transport services and the actual service quality provided. This was consistent across all commuter groups. In particular, the findings have been useful in shedding broad light on the areas where improvements are needed most, i.e. responsiveness and reliability of services, to encourage greater use of public transport within the community level.

Viability of small‐scale arsenic‐contaminated‐water purification technologies for sustainable development in Pakistan
Authors: Hashmi Fatima , Pearce Joshua M. 
Published: May 2009

AbstractDrinking arsenic‐contaminated water leads to a series of health problems that has limited development for the largely poor rural people of Pakistan who are unable to afford bottled water, centralized treatment plants or expensive water filter systems. This paper reviews the available appropriate technologies for the removal of arsenic from drinking water to assist in just sustainable development in Pakistan. Several technologies were found to be both technically and economically viable, supporting the large‐scale deployment of these small‐scale, appropriate technologies. The economic viability determined in this study was based on both first costs and operating costs. The cost of implementing such technologies for an individual Pakistani family is made acceptable with the use of local materials, which the family may already own. For example, systems using sand and iron nails in the filters, and that are placed in plastic buckets that are already in common use in the villages, drive down the overall costs of the technology and put it in the reach of even the most destitute. This study found that complications from the variability of local supplies result in the need to identify the locally most appropriate solution from both a technical and economic standpoint. This review article should be helpful for any practitioner in determining the locally optimal solution for the removal of arsenic from drinking water in Pakistan.

Biosurfactants from Urban Wastes for Detergent Formulation: Surface Activity and Washing Performance
Authors: Savarino Piero , Montoneri Enzo , Musso Giorgia , Boffa Vittorio 
Published: May 2009

AbstractTo promote biobased products for industry, six biosurfactants (BS) isolated from green and food urban residues aged under aerobic digestion for 0–60 days were investigated for their chemical composition, surface activity properties and detergent performance in fabric washing in comparison with commercial anionic and nonionic surfactants (CS). The BS exhibited a range of chemical composition and surface activity properties presumably related to their different biomass sources. Surface tension data for these substances correlated meaningfully with performance data in fabric washing. It was found that BS have similar performances as CS when used neat, but the 1:1 w/w BS–CS mixes are characterized by significant synergy. High sensitivity to water hardness and fabric yellowing were found to be the main deficiencies for the BS. However, both effects are minimized or are not critically evident when the BS are used together with CS and/or in common detergents formulations. The results indicate that when used above critical micellar concentration, no significant or critical performance differences are evident within the whole group of BS or between BS and CS. These facts encourage expectations for industrial production and real commercialization of BS as components of detergents formulations.

Abstract
New data on the age, composition, formation conditions, and ore-geochemical specialization of the Nui Chua layered peridotite-gabbro complex are reported. They evidence that the complex resulted from the Permo-Triassic mantle plume activity in northern Vietnam (southern framing of the Yangtze Platform). Two series of mafic and ultramafic rocks differing in ore productivity—layered (PGE-Cu-Ni) and pegmatoid (Fe-Ti-V)—have been recognized within the complex. The first estimates of the composition of their parental melts have been obtained.
The conditions of existence and typomorphism of native gold in ores of the Degdekanskoe deposit (northeastern Russia) in black-shale strata
Authors: Litvinenko I.S. 
Published: May 2009

Abstract
We studied the typomorphic features of native gold in orebodies with veinlet-disseminated quartz-sulfide mineralization at the Degdekanskoe deposit localized in Permian black-shale strata of the Ayan–Yuryakh anticlinorium in the upper-Yana–Chukchi folded area. With a successive HF and HNO3 dissolution of samples, the abundance of native gold intimately intergrown with sulfides (on the average, 42.1%) and carbonaceous substance was revealed. It is shown that most of its grains are small and fine (the &lt;0.25 mm fraction averages 90.2%) and are accumulated mainly in interstices. Two gold generations have been revealed: low-medium-grade (751–840‰) (main) and high-grade (885–931‰). The zonal structure of mineralization has been established. The upper, most enriched horizons bear coarser-grained gold of the two generations, which are localized in both sulfide and silicate minerals. With depth, the total content of gold decreases, the share of sulfide gold increases, and the grain size and grade also diminish, with the low-medium-grade generation prevailing.
The United Nations Economic Commission for Asia and the Far East
Authors: Schaaf C. Habt 
Published: May 2009

The bare facts about the history and organization of the United Nations Economic Commission for Asia and the Far East (ECAFE) are not difficult to relate. The commission was established in 1947 by the Economic and Social Council, along with two other regional economic commissions for Europe and Latin America, as a five-year experiment. Its terms of reference authorized it “acting within the framework of the policies of the United Nations and subject to the general supervision of the Council” and provided that it take “no action in respect to any country without the agreement of the Government of that country” to:(a) initiate and participate in measures for facilitating concerted action for the economic reconstruction of Asia and the Far East, for raising the level of economic activity … and for maintaining and strengthening the economic relations of these areas both among themselves and with other countries of the world;
The New Diplomacy and the Quest for Peace
Authors: Thompson Kenneth W. 
Published: May 2009

Parliamentary diplomacy in international organization has its roots in the movement toward “diplomacy by conference.” As early as 1928, Frederick S. Dunn could assert:The rapidity with which the conference method has come to the forefront in the conduct of international intercourse is one of the most striking developments in the present era of world affairs. Within the space of a very few years, this method has almost entirely supplanted bilateral diplomatic negotiation in matters of interest to more than two or three nations.
Establishment of the International Finance Corporation: A Case Study
Authors: Matecki B. E. 
Published: May 2009

This article presents briefly the findings of a case study in which two questions are investigated:a) Did the idea of an International Finance Corporation, first publicly expounded by the United States International Development Advisory Board, have its source in a United States agency or in an international organization?b) What were the causes of the modification of policy announced by the United States government on November II, 1954, when it decided to support the establishment of the International Finance Corporation, and did international organizations have any part in bringing about this change of policy?
The changing relationship between the World Bank and the International Monetary Fund
Authors: Feinberg Richard E. 
Published: May 2009

The World Bank and the International Monetary Fund have been bedeviled since their common creation over how to define their areas of specialized competence and how to interact in areas of overlapping jurisdiction. The multiple shocks that have destabilized the global economy over the last two decades have stimulated the Bank and Fund to alter fundamentally their programs and approaches, often without fully taking into account their relation to the work of the other Bretton Woods agency.The Fund's traditional focus on short-term stabilization, correcting external account imbalances, and fighting inflation, contrasted with the World Bank's provision of long-term funds for investment in capital-intensive projects. But more recently, with the establishment of the IMF's Extended Fund Facility and the Bank's structural adjustment lending, both institutions share the objective of adjustment with growth, and each claims some responsibility for an extremely wide range of policy instruments. The new Structural Adjustment Facility, in particular, has the potential to link more tightly decision-making on Fund stand-by arrangements and Bank structural adjustment lending, increasing the probability of new forms of cross-conditionality—termed here consultative cross-conditionality, interdependent cross-conditionality, and indirect financial linkage.The Bank and Fund need to find ways to better delineate and manage their new relationship. Problems that should be addressed to do so include proper modes of collaboration between Bank and Fund staff, issue specialization, the avoidance of piling on excessively detailed performance requirements, and decisions on ineligibility. Enhanced cooperation between the Bank and Fund can not only produce more coherent adjustment programs, but can also help to mobilize other sources of official and private capital.
Washington and Bonn: dimensions of change in bilateral relations
Authors: Johnson Paul M. 
Published: May 2009

In recent years efforts to account for changing patterns of alliance relationships have incorporated a growing number of insights and propositions derived from the analysis of “global interdependence.” These efforts have been complicated, on the one hand, by a lack of precision in providing operational definitions of the independent variables and, at a more fundamental level, by considerable ambiguity with respect to those types of changes which may be best explained in terms of these variables.An analysis of Washington-Bonn relations reveals a reasonably coherent pattern of changes with regard to four specific aspects of the relationship: 1) the nature of the alliance agenda; 2) the structure of the relationship (i.e. the characteristic distribution of influence between alliance partners); 3) the operative procedural norms which regulate bilateral bargaining and negotiation; and 4) the institutional arrangements which have evolved for the coordination of alliance policy.
The abolition of slavery and the end of international war
Authors: Ray James Lee 
Published: May 2009

Slavery and war have both historically been considered inevitable consequences of human nature. Yet slavery has been abolished, and moral progress may have contributed to slavery's disappearance. Both realists and Marxists are skeptical about the impact of ethical constraints on political decisions, while idealists as well as at least some regime analysts emphasize the role of those constraints. However, elements of all of these approaches support the proposition that moral progress may bring an end to international war.Some historical trends do not support the idea that international war is on the verge of disappearance, but there has not been a war between major powers since 1945. In addition, norms against colonialism are strong. No war has occurred between democratic states, nor does a war appear likely among the rather sizable number of industrialized democratic states in the international system today. Explanations of these pockets of peace based on caution induced by nuclear weapons or on economic interdependence, for example, are certainly not beyond question. Therefore, it may be that norms inhibiting the initiation of international war have already made obsolete not only wars between the richest and most powerful states in the world but also some forms of depradation by the strong against the relatively weak states.
Taxation and the political economy of the tariff
Authors: Hansen John Mark 
Published: May 2009

Traditional accounts of U.S. tariff policy emphasize trade strategies and interest group politics. This article makes a departure. It opens with an observation: up until World War I, the tariff was the largest single source of federal government revenues. It then explores the significance of tariffs as taxes, theoretically and empirically.In its first part, the article develops a theory of taxation politics and applies it to the tariff. In its second part, it submits the theory to an empirical test, modeling changes in U.S. tariff rates from 1829 to 1940. The politics of tariff revision, it argues, followed from two characteristics of the tariff as tax: from the extent of the treasury's dependence upon it and from the distributive pattern of its burdens and benefits. Taken together, the article concludes, revenue dependence and distributive incidence account for several diverse aspects of American tariff policy, including the structure of its coalitions, the shifts in its objectives, and the timing of its innovations.
The occurrence of Angiostrongylus vasorum in terrestrial slugs from forests and parks in the Copenhagen area, Denmark
Authors: Ferdushy T. , Kapel C.M.O. , Webster P. , Al-Sabi M.N.S. , Grønvold J. 
Published: May 2009

AbstractA total of 298 slugs belonging to four species, Arion lusitanicus, A. ater, A. ater rufus and Limax maximus, were collected from six different localities within a radius of 30 km from Copenhagen and examined for naturally acquired Angiostrongylus vasorum infection. Overall, 28 slugs (9%) were infected, but the prevalence varied among the studied localities: Rude Forest (26%), West Amager Forest (18%), Jaegersborg Forest and Deer Park (8%), Frederiksberg Park (4%), Assistens Cemetery Park (0%) and Frederiksberg Botanical Garden (0%). Only third-stage larvae (L3) were recovered from the slugs, in numbers ranging from 1 to 392 per slug. Overall 82% of the infected slugs harboured fewer than 10 larvae and only 14% harboured over 100 larvae.
Local immune status and tumour marker expression in the human larynx
Authors: Nakashima T , Tomita H , Chitose S , Umeno H , Sato K 
Published: May 2009

AbstractThis study examined the local immune status and tumour marker expression in secretions and related tissue specimens from the laryngeal ventricle, comparing individuals with and without head and neck cancer. Laryngeal secretion and mucosal tissue specimens were collected during laryngeal microsurgery or surgical laryngectomy. The laryngeal secretions were found to contain immunological factors such as immunoglobulins G and A and secretory immunoglobulin A. A high level of the tumour marker Cyfra 21-1 was also detected in laryngeal secretions and mucosal tissue. Lows levels of secretory immunoglobulin A and Cyfra 21-1 were seen in the laryngeal mucosal tissue of controls and patients who had previously undergone radiation therapy. The level of secretory immunoglobulin A in laryngeal secretions closely correlated to the level of this immunoglobulin in mucosal tissue. These results indicate that local immunity is present in the human larynx; furthermore, it is strongly affected both by the presence of malignancy and by laryngeal cancer treatments such as irradiation.
Expression of dendritic cell phenotypic antigens in cervical lymph nodes of patients with hypopharyngeal and laryngeal carcinoma
Authors: Li X , Takahashi Y , Sakamoto K , Nakashima T 
Published: May 2009

AbstractBackground:The purpose of this study was to assess the presence of dendritic cell phenotypic antigens in the cervical lymph nodes of patients with hypopharyngeal and laryngeal carcinoma, and to assess the significance of such antigens in the tumour immune reaction.Methods:Immunohistochemical staining of cervical lymph nodes was performed using antibodies against cell surface markers such as S-100 protein and cluster of differentiation 1a and 83 glycoproteins. Two hundred and seventy-four cervical lymph nodes obtained at surgery from 37 patients with hypopharyngeal carcinoma and 31 patients with laryngeal carcinoma were thus evaluated.Results:The number of dendritic cells positive for each phenotypic antigen was significantly greater in non-metastatic lymph nodes than in metastatic lymph nodes. In the metastatic lymph nodes, cluster of differentiation 1a glycoprotein positive dendritic cells were predominantly detected in the cancer ‘nest’, whereas mature dendritic cells staining for cluster of differentiation 83 glycoprotein were prominent in the peritumour area. In the metastatic lymph nodes, in contrast to the cluster of differentiation 1a glycoprotein positive dendritic cells, the degree of infiltration of cluster of differentiation 83 glycoprotein positive dendritic cells was significantly higher in the peritumour area than in the cancer nest. There was a significant difference in survival status, comparing patients with different degrees of dendritic cell infiltration for each type of phenotypic antigen.Conclusions:Dendritic cells may play different roles in tumour immunity against hypopharyngeal and laryngeal carcinoma. The phenotypic antigens of dendritic cells may thus constitute important indices with which to predict the prognosis of patients with hypopharyngeal and laryngeal carcinoma.
Overexpression of Cap43 gene in supraglottic laryngeal squamous cell carcinoma
Authors: Li X , Sakamoto K , Takahashi Y , Nakashima T 
Published: May 2009

AbstractObjective:This study aimed to determine the expression of the Cap43 gene in supraglottic laryngeal squamous cell carcinoma, and to evaluate any correlation between Cap43 gene expression and tumour-associated macrophage infiltration.Methods:Four human head and neck squamous cell carcinoma cell lines were cultured (Hep2, KB, Ca9-22 and HSC-3) and expression of the Cap43 gene was analysed by Western blotting. In addition, paraffin-embedded samples of supraglottic laryngeal squamous cell carcinoma and normal supraglottic laryngeal mucosa from 84 patients were analysed immunohistochemically using antibodies to Cap43 and cluster of differentiation 68 glycoprotein. Patients' clinical status was compared with their immunohistochemical results.Results:All four head and neck squamous cell carcinoma cell lines exhibited Cap43 expression. The Hep2, Ca9-22 and HSC-3 cells showed a markedly higher level of Cap43 protein than the KB cells. A statistically significant difference was found in Cap43 expression, comparing different differentiation levels and comparing different metastasis stages, for supraglottic squamous cell carcinoma. The number of tumour-associated macrophages correlated with expression of Cap43, not only in the tumour area (r = 0.3708, p = 0.0005) but also in the peritumour area (r = 0.2847, p = 0.0087).Conclusion:In supraglottic laryngeal squamous cell carcinoma, overexpression of the Cap43 gene is associated with tumour differentiation and acts an important suppressive factor in the process of tumour metastasis. The Cap43 gene may be a cancer-specific marker. High expression of the Cap43 gene appeared to correlate with infiltration of tumour-associated macrophages.
Repair with sternohyoid muscle fascia after subtotal laryngectomy
Authors: Dong P , Li X , Wang G , Chen X , Xie J , Nakashima T 
Published: May 2009

AbstractBackground:The subtotal laryngectomy procedure enables the patient to avoid some of the serious consequences of total laryngectomy without having to relinquish oncological effectiveness. However, the important complication of aspiration may still seriously affect some patients. Many methods of reconstruction have been described in an attempt to avoid or minimise this complication.Methods:Thirty-nine patients (15 with supraglottic laryngeal cancer and 24 with hypopharyngeal cancer) who had undergone subtotal laryngectomy between 2000 and 2006 were included in this study. In all patients, a sternohyoid muscle flap has been used for primary, one-stage reconstruction of laryngopharyngeal defects, following resection of advanced stage lesions. Patients' times to oral intake and decannulation, their speech function and their post-operative complications were reviewed.Results:The patients' three-year overall survival rate was 46.1 per cent. Their mean time to oral intake was 14 days. Twenty-six patients were decannulated (66.7 per cent). Almost all patients regained their speech function post-operatively, although their voice quality was not as good as before surgery.Conclusions:Sternohyoid muscle fascia reconstruction leads to optimal repair of subtotal laryngectomy defects and restored laryngeal function.
Histopathological study of correlation between laryngeal space invasion and lymph node metastasis in glottic carcinoma
Authors: Chijiwa H , Sato K , Umeno H , Nakashima T 
Published: May 2009

AbstractObjectives:The paraglottic space and cricoid area of the larynx are made up of loose, areolar tissue composed of loose elastic and collagenous fibres and adipose tissue. They contain the main blood vessels of the larynx. We examined the correlation between the histopathological extension of glottic carcinoma into the paraglottic space or cricoid area and the development of cervical lymph node metastasis.Study design:We reviewed the medical charts of 45 patients (44 men and one woman) who had undergone total laryngectomy for squamous cell carcinoma of the glottis between 1991 and 2003.Methods:Macroscopic and microscopic study of the removed larynges of the same patients was performed, and the histopathological evidence for invasion of the paraglottic space or cricoid area was analysed.Results:Eight of the 24 patients (33 per cent) with invasion of the paraglottic space or cricoid area had cervical lymph node metastasis. In contrast, only one of the 21 patients (5 per cent) without any evidence of invasion of either space had lymph node metastasis. This difference was statistically significant (p < 0.05). In the 36 patients free of cervical lymph node metastasis, recurrence in the neck occurred in six (38 per cent) of the 16 patients with paraglottic space or cricoid area invasion, but in only one (5 per cent) of the 20 patients without paraglottic space or cricoid area invasion (p < 0.05).Conclusion:In patients with glottic carcinoma, invasion of cancer into the paraglottic space or cricoid area is an important prognostic factor for the development of cervical lymph node metastasis.
