The relationship between the snowmelt flood and the establishment of non‐native brown trout (Salmo trutta) in streams of theChitoseRiver,Hokkaido, northernJapan
Authors: Kawai Hideyuki , Ishiyama Nobuo , Hasegawa Koh , Nakamura Futoshi 
Published: May 2013

AbstractFlow regime is one of the major determinants of establishment success for non‐native aquatic organisms. Here, we examine the influence of flow variability associated with snowmelt flood on the establishment success of non‐native brown trout in 10 streams in northern Japan. We regarded the presence ofAge‐0 brown trout as the index of the successful establishment. The emergence ofAge‐0 brown trout in our study region begins in May, a time that overlaps with the occurrence of snowmelt flood. The presence ofAge‐0 brown trout was negatively associated with flow variability, and it was also negatively associated with summer water temperature. Our results indicate that the non‐native brown trout tends to establish in the streams with smaller snowmelt floods and lower summer water temperatures. Brown trout is an invasive, non‐native species that is problematic all over the world, and effective management strategies for preventing their further expansion are urgently needed. This study suggests that river managers should recognise that stable streams such as spring‐fed streams (i.e., low flow and summer water temperature) and flow‐regulated streams, have a higher potential risk of brown trout invasion.
Contribution of environmental and spatial factors to the structure of stream fish assemblages at different spatial scales
Authors: Nakagawa Hikaru 
Published: May 2013

AbstractTo compare the contributions of environmental and spatial factors in structuring assemblages of temperate stream fish on different spatial scales, I evaluated the distance decay of fish assemblage similarity and correlations among species compositions, environmental factors and geographical locations at medium (inter‐reach scale, spatial extent 40 km) and fine (inter‐microhabitat scale, spatial extent <200 m) scales. Partial redundancy analysis and variation partitioning indicated that the ordinal rank of the relative importance of environmental and spatial factors differed among scales. At the medium scale, the distance decay of similarity of species composition was steep at approximately >10‐km scale, and the assemblage structure was simply explained by the distance between sites and several environmental factors (e.g., elevation and current velocity). In contrast, the distance between microhabitats explained only a small portion of the variance in species composition at the fine scale, and fish assemblages were affected by several spatial patterns of habitat (or some environmental features associated with those spatial patterns). Environmental factors at the fine scale (e.g., substratum characteristics and presence/absence of cover) correlated with each other and were spatially structured, and their contribution to species variance was smaller than that at the medium scale. These results provide evidence for scale‐dependent alternation of the rank of the relative importance of environmental and spatial factors in structuring assemblages of stream fishes via the turnover of crucially contributing factors from medium to fine spatial scales.
Streamlining the Muse: Creative Agency and the Reconfiguration of Charismatic Education as Professional Training in Israeli Poetry Writing Workshops
Authors: Wilf Eitan 
Published: May 2013

AbstractIn this article I seek to theorize recent institutional transformations of creative agency that involve the increasing embeddedness of art socialization in the professional and bureaucratic infrastructure of various sorts of educational organizations in the contemporary West. I argue that institutional art education involves the reconfiguration of charismatic education as professional training, and I suggest that this provides an opportunity to theorize the features shared between charismatic education and professional training against the backdrop of a research tradition that has viewed them as antithetical to one another. In doing so, I draw on ethnographic fieldwork I conducted in two Israeli poetry writing workshops, which draw their pedagogy from the rapidly growing field of creative writing programs in the United States.
Role‐Play and “As If” Self in Everyday Life
Authors: Shoshana Avi 
Published: May 2013

AbstractIn this article, I examine the use of role‐play strategy and its outcomes in field experiment conditions in the Boarding School for Gifted Disadvantaged in Israel. Data derive from two major sources: governmental protocols related to the organizational production of a role‐play technique and interviews with graduates of the experimental school years after their role‐playing experience. Analysis of governmental protocols shows the intentional organizational usage of the term gifted within the school population is based on a bureaucratic simulation of giftedness, which in turn creates a distinction between natural giftedness and institutional giftedness. In‐depth interviews with graduates of the school indicate that they experience their giftedness as artificial (“as if” giftedness). They describe ethnic conversion and distinction between two types of self (before and after the boarding school). My concluding discussion identifies a particular kind of reflexivity (the presence of absence) in the boarding school graduates’ concepts of self. In turn, this reflexivity indicates phenomenological consequences latent in role‐play simulations in field experiment conditions. The findings of this article enable me to address a pertinent issue of psychological anthropology not sufficiently discussed in the literature: the manner in which individuals who experience (re)construction of the self maintain their selfhood many years after the (re)construction.
“My Heart Opens and My Spirit Flies”: Musical Exemplars of Psychological Flexibility in Health and Healing
Authors: Koen Benjamin D. 
Published: May 2013

AbstractAcross several disciplines in the health and social sciences, psychological flexibility is gaining in influence and explanatory power as a conceptual frame to better understand diverse cultural and clinical contexts of health and healing. Although music as a potential primer of psychological flexibility is seldom considered in extant research, key contributions have framed aspects of music's potential efficacy to promote health and healing within the construct of psychological flexibility. Building from this research and from studies in psychology and anthropology concerned with flexibility, and based on field research I conducted in the Pamir Mountain region of Tajik Badakhshan, I explore how the preeminent genre of Pamiri devotional music, known asmaddoh,facilitates or primes psychological flexibility for participants. In this case study, priming a state of psychological flexibility is accomplished by engaging specific cultural exemplars found in the natural and built environments, the local belief system, poetry, prayer, and music, creating a multilayered network of flexibility.
Embodied Identity and Political Participation: Squatters’ Engagement in the Participatory Budget in Brazil
Authors: Walker Ana Paula Pimentel 
Published: May 2013

AbstractIn this article I examine subjective identity transformations among those who take part in programs of participatory governance, particularly the innovative mechanism of municipal resource allocation called the Participatory Budget. Focusing on the engagements of Porto Alegre city squatters, I aim to capture ambivalences that distinguish local and international discourses of participation and private property. Building on the dialectical relationship between narrative/figured worlds and positional identities, I view the Participatory Budget as a framework of meanings in flux within which some squatters who rearrange their positional identities along lines of social and power relations are then empowered to change their political practices. A novel emphasis on the distinction between squatters’ positional and embodied identities allows me to assess the political and psychological impacts of this form of participatory governance for people living in squatter settlements. I demonstrate the importance of embodied political practices and locally situated notions of male and female bodies in the squatters’ appropriation and refashioning of the identities imposed by local and international organizations.
“The Wrong Holy Ghost”: Discerning the Apostolic Gift of Discernment Using a Signaling and Systems Theoretical Approach
Authors: Lynn Christopher Dana 
Published: May 2013

AbstractI develop a case study of demonic glossolalia (speaking in tongues) for its cues in conveying religious commitment among a congregation of Apostolic Pentecostals. From the perspective of signaling theory, costly or hard‐to‐fake signals may convey psychological dispositions of members and would‐be members toward an inclusive community. I utilize signaling theory in a broader systems approach to make sense of an incident of speaking in tongues that a congregation decries as demonic. To facilitate this interpretation, forms and motivations of glossolalia—the sine qua non that one has accepted Jesus as personal savior—are described and examined, including examples of calm and excited “Holy Ghost” and “backslider” and “mistaken demonic” glossolalia. To an outsider, some of the differences among these signaling modes may be difficult to distinguish, but the underlying religious and family dynamics provide insights as to how church members make distinctions they attribute to the spiritual “gift of discernment.” This approach promises to make unique contributions toward understanding the implicit folk psychologies of practices that, according to Pentecostals, mark them as “weird” or “odd.”
Seventy years of changes in the abundance of Danish charophytes

Published: May 2013

Summary

Charophytes grow attached to soft bottoms in ponds, streams, lakes and estuaries and are highly threatened throughout Europe according to the national Red Lists. We used Danish studies on freshwater charophyte distributions conducted around 1940 and repeated measurements during recent years to evaluate the historical development of species richness and dominance patterns. We also tested to what extent historical changes of species abundance in 29 waterbodies were related to landscape features, water quality and species traits.

We found that three species of freshwater charophytes (Chara filiformis, Tolypella intricata and Nitella gracilis) have apparently disappeared from Denmark while one species (Chara connivens) has immigrated. National species richness has thus declined from 21 to 19 species.

Species abundance based on occurrence in many waterbodies followed a linear rank–log abundance relationship both in the historical and the recent studies. The dominance structure was stronger today than historically as common species have become relatively more abundant and uncommon species relatively rarer.

Among species traits, perenniality and preference for alkaline waters typical of deep‐growing species in large alkaline lakes, a rare contemporary habitat, were significantly related to the historic species decline. Species increasing in abundance had wide tolerances to alkalinity and water nitrogen content.

Twenty‐nine lakes and ponds studied repeatedly showed a significant decline of mean species richness from 3.4 to 2.4 during the 70 years. A small increase in species richness has taken place during the recent 15–20 years in several lakes experiencing reduced nutrient loading. However, many species survive today in relict populations and may find it difficult to recolonise lakes in which water quality has improved.

The historical decline of species richness was significantly related to higher nutrient concentrations, higher phytoplankton biomass and lower transparency of eutrophied waterbodies. In contrast, the amount of wetlands and openness of the landscape close to a waterbody did not predict the historical development perhaps because local processes or long‐distance dispersal determine species richness.

Considering together the loss of former freshwater habitats and the deterioration of surviving habitats, we conclude that charophyte occurrence has declined by about 56% in Denmark during the last 70 years. Species reductions determined from the reinvestigated waterbodies (29%) and the national species list (10%) are much lower and are less suitable measures of the developmental status of charophytes.

Published: May 2013

AbstractAimMany mangrove communities form bands parallel to the shoreline with each community dominated by a single species. However, the key determinants of mangrove species distribution across the intertidal zone are not well understood. We aimed to quantify the relationship between species' dominance and the hydroperiod (defined as the duration of inundation in a year), soil salinity and the salinity of inundating water for three dominant species,Sonneratia alba,Rhizophora stylosaandCeriops tagal.LocationAn extensive (20,000 ha), largely intact mangrove forest in northernAustralia, of some note as mangrove forests are threatened globally.MethodsWe related species dominance to the explanatory variables by applying two statistical modelling approaches: generalized linear models (GLMs), where a set of competing models were evaluated; and boosted regression tree models (BRTs), an approach that automatically captures interactions and nonlinear relationships between variables.ResultsBothGLMandBRTmodels achieved strong predictive performance for all species based on cross‐validation, with receiver operating characteristics above 0.85 for all species, and 88% of deviance explained forS. alba, 42% forR. stylosaand 35% forC. tagal. All models indicated that the hydroperiod was the key variable influencing distribution, followed by soil salinity. The salinity of inundating water was the least informative variable in the models. Ecological space, determined by gradients in hydroperiod and soil salinity, was partitioned between the three species with little overlap.Main conclusionsAs anticipated changes in sea level will alter the hydroperiod, our findings are critical for global forecasting of future distributions of mangrove communities, and for the design of mitigation and adaptation measures.
Cardiac dysfunction and N‐terminal pro‐B‐type natriuretic peptide in exacerbations of chronic obstructive pulmonary disease

Published: May 2013

AbstractElevated levels of B‐type natriuretic peptides among patients with exacerbations of chronic obstructive pulmonary disease (COPD) are associated with higher mortality. The pathophysiology is unclear. To establish if elevated levels of N‐terminal pro‐B‐type natriuretic peptide (NT‐proBNP) are due to right or left heart dysfunction, we performed echocardiograms in 18 patients admitted to hospital with COPD. Elevated levels of NT‐proBNP were associated with both right and left heart dysfunction and indicate that these patients have biventricular dysfunction rather than isolated right ventricular compromise.
Early discharge and ambulatory care of low‐risk patients with neutropenic fever in Australia
Authors: Hocking C. , Taylor A. , Hayward A. 
Published: May 2013

AbstractNeutropenic fever commonly necessitates hospital admission following chemotherapy, contributing significantly to the economic cost of cancer management. Strategies utilising early discharge and ambulatory management with oral antibiotics have been demonstrated safe and effective internationally and included in recently published Australian guidelines. Here, we sought to evaluate this strategy for the first time in a controlled series in the Australian setting to allow ambulatory management for low‐risk patients to become the new standard of care at our institution.

Published: May 2013

AbstractUndiagnosed pheochromocytoma in pregnancy is associated with significant maternal and foetal mortality. Herein we reviewed five cases of pheochromocytoma in pregnancy occurring during late pregnancy. The mean age at presentation was 30.6 years, and the gestational age ranged from 26 to 36 weeks. All patients had elevated levels of urinary catecholamines. In three patients, the lesion was located in the adrenal gland, in one patient the urinary bladder, and there was one case of recurrent malignant pheochromocytoma with metastases. Tumour resections were performed at the time of Caesarean section in four patients, two through laparoscopy. When pheochromocytoma is diagnosed in pregnancy after the second trimester, concurrent tumour resection with Caesarean section is feasible and in our series was achieved in four cases without adverse maternal or foetal consequences.
Leukaemias into the 21st century – part 2: the chronic leukaemias

Published: May 2013

AbstractLike the acute leukaemias, the chronic leukaemias are broadly classified according to their cell lineage of origin. Chronic myeloid leukaemia and chronic lymphocytic leukaemia are the most common disease entities within the myeloid and lymphoid lineages, although several less common entities are well recognised within each broad subgroup. In common with the dramatic progress in the acute leukaemias, there has been considerable progress in our understanding of the biology and molecular genetics of the chronic leukaemias that is now being translated into significant therapeutic advances.
Times and Spaces of Homeless Regulation inJapan, 1950s–2000s: Historical and Contemporary Analysis
Authors: Hayashi Mahito 
Published: May 2013

AbstractSince the late 1970s,AtlanticFordism has seen rising homelessness and ghettoization as the ‘new urban poverty’ (NUP) (Mingione, 1996). Despite some similarities, theNUPinJapan has a unique rhythm and spatial pattern. In order to exploreJapaneseNUP, this article develops an interpretation ofJapan's strategies to regulate poverty and homelessness during the last 50 years, paying particular attention to the spatial consequences of such strategies within majorJapanese cities. First, I theorize long‐term economic growth patterns as a basic parameter of poverty and homelessness regulation and present a periodization ofJapanese trends since the 1950s. Second, I analyze poverty inJapan and the transformation of national strategies of spatial regulation in the 1990s, when homelessness grew. Third, I examine the multi‐scalar processes through which new regulatory spaces of homelessness were produced in the 1990s and 2000s, when failures of post‐bubble crisis management ballooned inJapan. I argue that, through a dialectic between national/local rule‐setting and homelessness, theJapanese state fragmented the dominant scale of poverty regulation, rescaled the site of homeless regulation and contained homelessness in relatively autonomized cities. I conclude that, from the 1990s until the late 2000s,Japan's homelessness and its contradictions tended to be transferred to the spheres of urban workfare and urban policing, which I call new regulatory spaces of homelessness, that lie around the fringes of national social rights.
The Influence of Avoidance Temperament and Avoidance‐Based Achievement Goals on Flow

Published: May 2013

AbstractIn the present research, we conducted two studies designed to examine the joint influence of avoidance temperament and avoidance‐based achievement goals on the experience of flow on a creativity task. In both a laboratory study (N = 101; Mage = 22.61, SDage = 4.03; 74.3% female) and a naturalistic study (N = 102; Mage = 16.23, SDage = 1.13; 48% female), participants high in avoidance temperament were shown to experience greater flow when performance‐avoidance goals were induced; no differences were found in any of the other three achievement goal conditions from the 2 × 2 achievement goal framework. These findings reveal a short‐term benefit for a disposition‐goal match grounded in avoidance motivation, and point to the need for more research on both avoidance‐based matches and the short‐term versus long‐term implications of such matches.
Dopamine release by Ulvaria obscura (Chlorophyta): environmental triggers and impacts on photosynthesis, growth, and survival of the releaser

Published: May 2013

In the NE Pacific, Ulvaria obscura is a common component of “green tide” blooms. It is also the only alga known to produce dopamine, which is released into seawater on sunny days when Ulvaria is emersed and then rehydrated. To better understand the mechanisms associated with dopamine release, we experimentally determined whether light quantity and quality, desiccation, temperature, exudates from conspecifics, and dissolved dopamine caused dopamine release. We also examined the effects of desiccation on Ulvaria's ability to photosynthesize, grow, and survive. Desiccation was the only factor that caused significant amounts of dopamine to be lost from U. obscura tissues. The loss of water from Ulvaria tissues was strongly and positively correlated with the loss of dopamine after rehydration. Only 56% of desiccated algae survived for 1 week, compared to 100% of undesiccated control algae. Desiccated algae lost 77% of their pigmented surface area and grew only 15% as much as undesiccated algae, which remained fully pigmented. The oxygen saturation of water containing Ulvaria that was desiccated and then rehydrated was significantly lower than that of seawater containing undesiccated algae. Thus, desiccation, which is coupled with dopamine release, is associated with the deterioration and death of some, but not all, tissues in Ulvaria. Although dopamine released into seawater can reduce the survival or growth of potential competitors, its release is associated with significant physiological stress and tissue mortality. However, the survival and continued growth of some Ulvaria tissues indicates that a net fitness benefit to release dopamine following desiccation cannot be ruled out.
Nitric oxide in the breath of bottlenose dolphins: Effects of breath hold duration, feeding, and lung disease

AbstractBreath analysis, including measurement of nitric oxide (NO), is a noninvasive diagnostic tool that may help evaluate cetacean health. This is the first report on the effects of breath hold duration, feeding, and lung disease on NO in dolphin exhaled breath. Three healthy dolphins were trained to hold their breath for 30, 60, 90, and 120 s and then exhale into an underwater funnel. Exhaled NO values from 157 breath samples were compared among three healthy dolphins by breath hold time and after fasting and feeding. Exhaled NO values were also measured in two dolphins with pulmonary disease. NO in dolphin breath was higher compared to ambient air; healthy dolphins had higher NO concentrations in their breath after feeding compared to after overnight fasting; and there were no significant differences in exhaled NO levels by breath hold duration. A dolphin with Mycoplasma‐associated pneumonia and chronic gastrointestinal disease had higher postprandial exhaled NO levels compared to healthy controls. This study demonstrates, contrary to previous publications, that dolphins exhale NO. Given the high standard deviations present in exhaled breath NO values, future studies are needed to further standardize collection methods or identify more reliable samples (e.g., blood).
