Interpretative Freedom and New Combination: The Way in Which the “Middle Class” Has Been Narrated
Authors: ONOUE MASATO 
Published: October 2010

AbstractThe English words “middle class” have experienced much more connotations and denotations—typically “bourgeoisie,” “white‐collar,” and professional—than any other class‐referring word since the latter half of the 18th century. On the one hand, in response to such diverse narrations during about two and a half centuries, I partially agree with some of the nominalistic theories of class, in that the middle classes were not created until they were named by contemporaries. On the other hand, my view diverges from those theories, in my asserting that the contemporaries have had an interpretative freedom to recognize “middle classes” only within the bounds of plausibility on the side of the realistic social world. The typical middle class in each period has emerged in such a way that Schumpeter's new combination is performed in a stage of recession by new entrepreneurs, who will move into the “middle” strata and hold some cultural leadership but still obtain inconsistent statuses, to be recognized as “middle class”ex post facto in a boom time. Two Kondratieff's cycles have had one recognition of the typical “middle class.” The new combination is one of the pressures bringing middle classes into a modern society, contrary to the so‐called class decomposition into the two poles.
Identity Management among Indonesian and Filipina Migrant Domestic Workers in Singapore
Authors: UENO KAYOKO 
Published: October 2010

AbstractThis study examines how the identities of migrant domestic workers are likely to be endangered and how these individuals struggle to reconstitute them. It is largely based on an interview and observational study with Indonesian and Filipina domestic workers in Singapore. Inspired by the sociological discussion of Goffman and Ishikawa, the study reveals how each migrant domestic worker manages her identity in her specific social context. This study shows that domestic workers contrive tactics to negotiate their situations, given that domestic work is considered a low prestige occupation and workers tend to be divested of the usual “identity kit” to make up their identity front. Specifically, to compensate for their discredited status, domestic workers attempt to reconstitute their damaged identity, obtain a new identity kit, recall previous social and family roles, or anticipate a future identity. They also attempt to acquire new skills and increase their value, so they can identify themselves as more than “just a maid.” They obtain additional roles in an attempt to change how they feel about themselves, to alter the meaning of being a domestic worker, and to redefine their relationships with others either by individual struggles or through collective activities. This study also points out a possible pitfall of identity management among the actors. The mechanism of identity politics might lead to an erosion of value, alienation from other domestic workers, and a strengthening of conventional stereotypes and generalizations regarding ethnicity, nationality, and gender. In this context, how non‐governmental organizations play a role in mitigating the pitfalls of identity management among domestic workers is also examined.
Tamito Yoshida: An Unknown Master of Japanese Sociology
Authors: HASEGAWA KOICHI 
Published: October 2010

AbstractThis paper outlines the life and academic accomplishments of the largely internationally unknown but foremost innovative and leading sociologist of Japan considered as the “unknown master” of Japanese sociology, Tamito Yoshida. (i) Emphasizing originality and creativity, Yoshida's success was free from the existing sociological frameworks and he liberated theoretical study from the yoke of historical perspectives that had long governed Japanese theoretical sociology. (ii) Yoshida's uniform scientific approach that used the keywords of information, selection, and variation based on evolutionist ideas was consistent throughout his life from proposing the “design of information science” in his mid‐thirties to proposing the concept of “program sciences” in his later years. (iii) One of Yoshida's major sociological contributions was in identifying the close relationship between subjectivity and the structure of possession. (iv) Yoshida's “A Historical Perspective on the Forces and Relations of Production” is an original and critical re‐creation of the Marxist possession theory located within his own theoretical framework, and is an excellent critique of the central arguments of Marxism. It successfully illustrates Yoshida's superlative critical and creative skills of theoretical dialogue.
Yoshida Theory: Its Structure, Criticism and Advancement
Authors: SHIDA KIYOSHI 
Published: October 2010

AbstractTamito Yoshida, a giant of theoretical sociology, passed away in 2009. Here, I give a concise review of his theoretical achievements, called “Yoshida Theory”, and foresee the future. The main features of Yoshida Theory are the following: information controls resources; there was evolution from the stage of only materials to that of materials controlled by generic information and also to that of materials controlled by symbolic information; the process of information procedures is divided into “to cognize,”“to evaluate” and “to order,” which are distinguished from one another, and from the theoretical standpoint called the “Information Processing Resources Paradigm”; information is maintained as long as it is useful, and when it becomes useless it is selected or expected to be changed. There was much criticism against the theory. The most unrelenting opposition was that it was not a system of explanation in the conventional sense of scientific methodology. It was claimed not to be positive scientific theory because of the logical inconsistency. Yoshida's counter‐criticism was, contrary to his opposites' expectations, that sociological theory ought not to fulfill the criteria to be science. It seemed to support his evolutionalist assertion that the synchronically inconsistent theory will be corrected diachronically and achieve some consistency. The criteria of science themselves should be re‐constructed to thematize the fact that information or program‐controlling society has evolution, he thought. He called it “New Science”; however, the attempt was never completed. It is still our task to clarify whether sociological theory can remain in science or not.
Organ Transplantation as a Family Issue: Living Liver Donors in Japan
Authors: MUTO KAORI 
Published: October 2010

AbstractThe global criticism of organ trafficking and transplant tourism requires many countries to pursue legal protection of living organ donors for organ transplantation. Japan is one of the criticized countries: more than 26 000 people have become living organ donors. This paper presents an exploration of living liver transplantation in Japan from legal, social and ethical perspectives. Since the first living liver transplantation in 1989, the cases have increased, with extremely high dependency in spite of a few deaths and cases of severe disability. Government and professional guidelines stipulate that living donors be “relatives” so that living organ transplantation can be privatized and regarded as a family issue, although it is strictly limited to altruistic cases in some countries. Based on results of the Living Liver Donor Survey conducted in 2004, Japanese liver donors have had various experiences. Most male donors were employed, felt some obligation and had concerns about financial effects or employment during decision‐making. In contrast, only a quarter of female donors were employed, felt guilty for their children, and did not have opportunities for regular health checkups after donation. Severe tensions and family break‐up were observed in adult‐to‐adult cases, although donors were satisfied with donation overall. The author suggests that we should rethink privatization of living organ donation and that independent advocates should support potential donors. Further research is necessary to explore the reasons why organ donation is privatized even in some forms of cadaver cases in Japan.
Interaction of an Idealized Cavopulmonary Circulation With Mechanical Circulatory Assist Using an Intravascular Rotary Blood Pump

Published: October 2010

AbstractThis study evaluated the performance of an intravascular, percutaneously‐inserted, axial flow blood pump in an idealized total cavopulmonary connection (TCPC) model of a Fontan physiology. This blood pump, intended for placement in the inferior vena cava (IVC), is designed to augment pressure and blood flow from the IVC to the pulmonary circulation. Three different computational models were examined: (i) an idealized TCPC without a pump; (ii) an idealized TCPC with an impeller pump; and (iii) an idealized TCPC with an impeller and diffuser pump. Computational fluid dynamics analyses of these models were performed to assess the hydraulic performance of each model under varying physiologic conditions. Pressure‐flow characteristics, fluid streamlines, energy augmentation calculations, and blood damage analyses were evaluated. Numerical predictions indicate that the pump with an impeller and diffuser blade set produces pressure generations of 1 to 16 mm Hg for rotational speeds of 2000 to 6000 rpm and flow rates of 1 to 4 L/min. In contrast, for the same flow range, the model with the impeller only in the IVC demonstrated pressure generations of 1 to 9 mm Hg at rotational speeds of 10 000 to 12 000 rpm. Influence of blood viscosity was found to be insignificant at low rotational speeds with minimal performance deviation at higher rotational speeds. Results from the blood damage index analyses indicate a low probability for damage with maximum damage index levels less than 1% and maximum fluid residence times below 0.6 s. The numerical predictions further indicated successful energy augmentation of the TCPC with a pump in the IVC. These results support the continued design and development of this cavopulmonary assist device.
Stem Cell Research and Technology in Iran—Window of Opportunity in the Midst of International Tension
Authors: Miremadi Tahereh 
Published: October 2010

AbstractThis paper aims to explain how the key characteristics of “stem cell research” as an emerging technology facilitate the strategy of an Iranian organization, namely, “the Royan Institute” to learn by interaction and to generate knowledge. It argues that the Royan could take advantage of the window of opportunity that stem cell research and technology had temporarily opened up but its endeavors are now being hampered by unfavorable international factors and weak domestic infrastructure. The article substantiates the case by giving an objective account of networking and gatekeeping in the process of learning/innovation at the Royan and concludes by questioning the continuity of the actual learning strategy in order to sustain the Royan's knowledge production.
Environmental Federalism Revisited: Second‐Order Devolution in Air Quality Regulation
Authors: Woods Neal D. , Potoski Matthew 
Published: October 2010

AbstractIn this paper we examine states' use of local clean air agencies and provide a preliminary assessment of what causes states to devolve air quality policy authority to the local level. Data from a unique comparative state survey shows that states vary widely in the number of local clean air agencies they employ and the amount of authority these agencies have to set standards, monitor air quality, and enforce regulations. Multivariate analyses suggest that second‐order devolution is partly driven by a general propensity to decentralize policy authority, but that policy‐specific factors relating to the problem and interest group environment affect devolution as well. These findings indicate that local agencies play an important role in U.S. air quality regulation, and that the dynamics of state devolution to local agencies deserve further study.
Exploring Institutional Hiring Trends of Women in the U.S. STEM Professoriate
Authors: McNeely Connie L. , Vlaicu Sorina 
Published: October 2010

AbstractThe presence of women in the United States science and technology professoriate depends on various factors, including the availability of a pool of qualified women with relevant doctorates and the elimination of policy constraints and institutional barriers to professional access. Recognizing that initial hiring in related science, technology, engineering, and mathematics (STEM) fields is a crucial step affecting gender composition and representation at all levels in the academic hierarchy, we focus on hiring profiles in institutions of higher learning to examine related trends and practices. In addition to the significant and inversely proportional influence of initial hiring on future trends, differences were noted relative to public or private control of the university and other institutional characteristics, providing a basis for further analyses of institutional dynamics restricting or enhancing favorable hiring policies and practices for STEM women faculty.

Published: October 2010

AbstractA 44‐yr‐old man with IgG‐lambda multiple myeloma reached a complete response after induction chemotherapy and autologous stem cell transplantation and maintenance therapy with interferon α2b and prednisone 4 yr later, he presented an increase in the M‐protein plus extramedullary myeloma involvement with sacrum and clivus plasmacytomas. Treatment with bortezomib, cyclophosphamide and dexamethasone plus local radiotherapy was initiated. The patient developed a bilateral humeral pathological fracture. Surgical osteosynthesis of both humeri was performed with no immediate complications. Two months later, he developed a prominent swelling in both deltoid areas with fever and high serum LDH levels. X‐ray examination showed a displacement of bone fragments of both humeri. Humerus CT scan showed a bilateral fracture in proximal diaphysis with posterior displacement. A magnetic resonance of right scapular region revealed a very extensive infiltration originated in the humerus. A fine‐needle punction showed a diffuse plasmablastic infiltration. This case illustrates an atypical presentation of extramedullary myeloma with extensive soft‐tissue involvement, originated at the fractured lytic lesions, which was likely triggered by bone surgery. This direct mechanism of myeloma spread has been observed in experimental myeloma mouse models.

Abstract:  Calcium (Ca2+) is a critical regulator of many aspects of the Plasmodium reproductive cycle. In particular, intra‐erythrocyte Plasmodium parasites respond to circulating levels of the melatonin in a process mediated partly by intracellular Ca2+. Melatonin promotes the development and synchronicity of parasites, thereby enhancing their spread and worsening the clinical implications. The signalling mechanisms underlying the effects of melatonin are not fully established, although both Ca2+ and cyclic AMP (cAMP) have been implicated. Furthermore, it is not clear whether different strains of Plasmodium use the same, or divergent, signals to control their development. The aim of this study was to explore the signalling mechanisms engaged by melatonin in P. chabaudi, a virulent rodent parasite. Using parasites at the throphozoite stage acutely isolated from mice erythrocytes, we demonstrate that melatonin triggers cAMP production and protein kinase A (PKA) activation. Interestingly, the stimulation of cAMP/PKA signalling by melatonin was dependent on elevation of Ca2+ within the parasite, because buffering Ca2+ changes using the chelator BAPTA prevented cAMP production in response to melatonin. Incubation with melatonin evoked robust Ca2+ signals within the parasite, as did the application of a membrane‐permeant analogue of cAMP. Our data suggest that P. chabaudi engages both Ca2+ and cAMP signalling systems when stimulated by melatonin. Furthermore, there is positive feedback between these messengers, because Ca2+ evokes cAMP elevation and vice versa. Melatonin more than doubled the observed extent of parasitemia, and the increase in cAMP concentration and PKA activation was essential for this effect. These data support the possibility to use melatonin antagonists or derivates in therapeutic approach.

Larsen JK, Bendsen BB, Foldager L, Munk-Jørgensen P. Prematurity and low birth weight as risk factors for the development of affective disorder, especially depression and schizophrenia: a register study.Background:The present study examined whether low birth weight, prematurity or low birth weight adjusted for gestational age are risk factors for the subsequent development of affective disorder, especially depression.Methods:A population-based case–control design was applied to the Danish Medical Birth Register and the Danish Psychiatric Central Register to identify all individuals born between 1 January 1974 and 31 December 1990 and diagnosed prior to 29 August 2003 with affective disorder alone (ICD-10 F3; 4297 females, 1861 males), schizophrenia alone (ICD-10 F2; 1364 females, 2292 males) or both disorders (ICD-10 F3 + F2; 450 females, 405 males). The association between low birth weight and the risk of developing affective disorder and/or schizophrenia was analysed by conditional logistic regression analysis.Results:Low birth weight was found to be associated with a significantly elevated risk of developing schizophrenia alone (p = 0.021) and both affective disorder and schizophrenia (p = 0.024), and a non-significantly elevated risk of developing affective disorder alone (p = 0.063). The effect remained significant in the affective disorder and schizophrenia groups (p = 0.039) when correcting for gestational age (premature birth), but was lost in the group with both disorders. Premature birth per se was found to be associated with a significantly elevated risk of developing both affective disorder and schizophrenia (p = 0.00018), an effect that remained significant after adjustment for low birth weight.Conclusion:Prematurity and low birth weight were found to be risk factors for subsequent development of affective disorder (especially depression) and schizophrenia.

Rezin GT, Gonçalves CL, Daufenbach JF, Carvalho-Silva M, Borges LS, Vieira JS, Hermani FV, Comim CM, Quevedo J, Streck EL. Effect of chronic administration of ketamine on the mitochondrial respiratory chain activity caused by chronic mild stress.Objective:Recently, we reported that mitochondrial respiratory chain complexes I, III and IV were inhibited in the cerebral cortex and cerebellum of rats submitted to chronic mild stress (CMS) and that acute ketamine administration reversed this effect. Therefore, we investigated whether the inhibition of these enzymes may be reversed by chronic administration of ketamine.Methods:Adult male Wistar rats were submitted to CMS and chronically treated with ketamine. After 40 days of CMS, consumption of sweet food, adrenal gland weight, body weight and enzymatic activity of the complexes were measured.Results:We verified that CMS decreased the intake of sweet food, increased the adrenal gland weight and the control group gained weight after 40 days but the stressed group did not; ketamine administration reversed these effects. We also verified that chronic administration of ketamine reversed the inhibition of complexes I, III and IV in cerebral cortex. However, in cerebellum, only complex IV inhibition was reversed. The chronic ketamine administration partially reverses the inhibition caused by CMS.Conclusion:We hypothesise that CMS inhibits complexes I, III and IV activities and that chronic administration of ketamine administration partially reverses such an effect. Therefore, it seems reasonable to propose that ketamine administration might be a useful therapy for patients affected by major depression.

Published: October 2010

ABSTRACTObjectives: This multicenter prospective study was aimed to clinically evaluate implant behavior inserted in severely resorbed maxillae and restored 3 months after sinus grafting.Materials and Methods: In three clinical centers, 67 totally rough wide diameter implants were inserted during 30 consecutive sinus lifts. Computed tomography and panoramic analysis were preoperatively requested for each patient. Sinus grafting was performed using a nano‐crystalline hydroxyapatite sole bone filler; no membrane was used to cover the buccal window. Preoperative residual bone height ranged between 1–4 mm (mean value: 2.70 mm, standard deviation [SD]: 0.9 mm). Uncovering procedure was carried out following 3 months of healing; 2 weeks later, a definitive restoration was seated using platform switching concept. To monitor stability changes, resonance frequency analysis was performed and implant stability quotient (ISQ) values were collected at the first surgery (baseline, T0), at the abutment connection (T1), and at 2‐year follow‐up (T2). To measure bone changes, patients underwent panoramic analysis after 2‐year follow‐up. The image analysis software calculated the grafted bone height changes at level of implant site comparing preoperative and follow‐up panoramic films; the software compensated for eventual radiographic distortion.Results: Mean ISQ value was 35.7 (SD: 8.8) at baseline, 66.61 (SD: 4.76) at T1, and 77.9 (SD: 4.7) at T2. Statistically significant differences (p ≤ 0.005) regarding ISQ mean values were found between T1 and T0, as well as between T1 and T2. After 24 months of functional loading, only two implants were lost (cumulative survival rate: 97%). During the same observation period, the mean value of radiographic vertical height of grafted sinus was 13.75 mm (SD = 1.3 mm), with a mean gain of 11 mm.Conclusions: Within the limits of this study, despite preoperative residual bone height ranging 1 to 4 mm and absence of the membrane covering the buccal bone wall, maxillary sinus lift restoration 14 weeks after first surgery seems to be a reliable procedure using totally‐rough surfaced implants restored using platform switching concept and nano‐structured hydroxyapatite as sole bone filler.
