Bathing residents with dementia in long‐term care: critical incidents described by personal support workers
Authors: D’Hondt Allison , Kaasalainen Sharon , Prentice Dawn , Schindel Martin Lori 
Published: July 2011

Aim and objective.  The aim of this study was to describe and gain insight into the critical incidents depicted by personal support workers (PSWs) in long‐term care (LTC) related to bathing residents who have dementia.Background.  Residents with dementia in LTC often display responsive/protective behaviours during bathing. Consequently, bathing is a source of stress for PSWs who provide most of the personal care for LTC residents in Ontario, Canada.Design.  A qualitative descriptive study employing the critical incident technique (CIT) was used.Method.  Eight PSWs were interviewed and 24 incidents were collected and analyzed using thematic content analysis.Results.  Findings revealed that PSWs experience the following during bathing: managing responsive/protective behaviours, working with limited resources, and dealing with communication difficulties. Participants used various strategies to respond to these challenges; however, they reported limited strategies to manage the most challenging behaviours.Conclusions.  Many of the bathing strategies described by the PSWs in this study are found in the literature about best bathing practices in dementia care. However, it is evident that further work is needed to support PSWs to manage the most difficult physical responsive/protective behaviours that occur during bathing.Implications for practice.  This study has clear implications for knowledge translation.
Mahāmudrā: Natural Mind in Indian and Tibetan Buddhism
Authors: Jackson Roger 
Published: July 2011

AbstractMahāmudrā, usually translated as ‘the great seal’, is a vital term in the tantric traditions of Buddhist India and most schools of Tibetan Buddhism. In early Indian Buddhist tantras, it refers primarily to a hand‐gesture (mudrā) accompanying visualization meditation. In the later and more esoteric Indian Mahāyoga and Yoginī tantras, it denotes, inter alia, one of a sequence of experiential ‘seals’ to meditation; a ‘consort’ in sexual yoga practices; and a non‐dual gnosis in which great bliss and awareness of emptiness (śūnyatā) are inseparably conjoined. In the songs and treatises of the Indian great adepts (mahāsiddhas), Mahāmudrā is an index of ultimacy, regarded as the luminous, empty nature of mind, i.e. our buddha‐nature; a type of meditation for realizing mind’s nature; a set of unconventional practices that express that realization; and the final fruit of meditation, buddhahood. In Tibet, Mahāmudrā was known during the imperial period, but gained prominence only during the Tibetan ‘renaissance’ that began in the 11th century. Although a topic of analysis in nearly every Tibetan tradition, it is most central to the Kagyü, or ‘oral lineage’. Introduced to the Kagyü by Marpa and Milarepa, Mahāmudrā was popularized by Gampopa, who analyzed it from many angles, and suggested it was as much a practice rooted in the sūtras as in the tantras. Subsequent Kagyü masters developed Gampopa’s analysis further, produced anthologies of Mahāmudrā texts, and related Mahāmudrā to a variety of important Indian and Tibetan Buddhist ideas and practices. As a meditation practice, Mahāmudrā often is divided into sudden and gradual approaches. The sudden approach involves simply abiding in the natural mind, which is tantamount to buddhahood. Gradual approaches may involve complex tantric visualizations and the manipulation of forces within the subtle body or a sequence of meditations that focus on the nature of mind, which is found to be empty, luminous, non‐dual, and blissful. Discourse on mahāmudra in India and Tibet raises a number of important issues for Buddhist thought and practice, such as the soteriological sufficiency of a single, sudden insight; the place of reason and ethics in contemplative tradition; and the unity or diversity of meditative realization. Those issues resonate, in turn, with discussions elsewhere of mysticism, religious experience, and the nature of mind.
Hittite Religious Rituals and the Ideology of Kingship
Authors: Gilan Amir 
Published: July 2011

AbstractWhat did the victorious Hittite king do on his return home from battle? Surprisingly perhaps, the pertinent Hittite sources offer different, even contradictory answers to this question. For a study of the relations between ritual practices and political power in the Hittite Kingdom, however, the question is not without interest. The occasion of the victorious return of the king from battle lends itself splendidly to, even calls for, a conscious use of ritual activity for the manifestation of political power. It will be argued that the evidence concerning the ritual activities of the Hittite king on his return from war show no conscious attempt to mould ritual practices into political goals or to exploit the glory of battles just won for a demonstration of power. This fact may shed a new light on the relations between ritual activity and political power in the context of the Hittite empire and its characteristic textual inheritance.
New Religious Movements in Animated Adult Sitcoms—A Spectrum of Portrayals
Authors: Feltmate David 
Published: July 2011

AbstractAs globally syndicated television programmes that are celebrated for their biting satirical content, The Simpsons, South Park, and Family Guy are popular culture phenomenons. Furthermore, they are programmes which have consistently featured a wide variety of religious traditions, including a significant selection of new religious movements (NRMs). This article provides an overview of the different movements depicted in the programmes, categorizing them as accepted, annoying, misguided, untrustworthy and dangerous. It concludes with a discussion of this pattern’s significance, and suggests avenues for future analysis of NRMs’ humorous depictions in popular culture.
Transnational Feminism in Sociology: Articulations, Agendas, Debates
Authors: Patil Vrushali 
Published: July 2011

AbstractWhat is the current terrain of transnational feminism in sociology? This essay begins by introducing the key interdisciplinary writings that helped initiate a specifically transnational feminist approach in women’s and gender studies. It then delineates three primary ways in which these writings have been adapted and/or expanded with/in sociology, as well as some points of tension and debate among these varying approaches. It argues that although there are numerous sociologically oriented transnational feminisms, most authors do not acknowledge this multiplicity and complexity, contributing to a sometimes confusing conversation where assumptions about key concepts, causality, and processes remain unclear. The essay ends with suggestions for future research.
Institutionalizing Scientific Knowledge: The Social and Political Foundation of Empirical Economic Research
Authors: Reichmann Werner 
Published: July 2011

AbstractScientific knowledge is an essential component of modern society. Consequently, sociologists are interested in its production process and have conducted a broad variety of studies showing how social patterns influence the definition and the boundaries of scientific knowledge. In this paper, I ask how social factors influence the transformation of a ‘normal’ field of knowledge into a ‘scientific’ one. First, I give a brief overview of the development of the sociology of scientific knowledge exploring different approaches to the social foundations and boundaries of scientific knowledge. Second, I present a case study of the transformation of empirical economic research in the 1920s from a field of knowledge produced by journalists and civil servants into a prestigious scientific domain. I use neo‐institutionalist ideas to show that knowledge needs a socially legitimated organizational frame in order to count as ‘scientific’ and I examine how political needs to ‘manage the economy’ build boundaries around economic knowledge and define it as ‘scientific’ in order to control its production, distribution, and communication.
‘A New Language that Speaks of Change Just As It Steps Toward It’: Transnationalism, Erotic Justice and Queer Human Rights Praxis
Authors: Collins Dana , Talcott Molly 
Published: July 2011

AbstractLesbian, gay, bisexual and transgender (LGBT) movements have too often been dominated by US liberal individualist framings of lesbian and gay rights, resulting in the hegemony of US‐focused issues and institutional actions, despite the irony that the US government has been relatively unsupportive of LGBT rights on the international stage. We argue that transnational, grassroots queer movements embody more profound aspirations that do not limit the meaning of queer liberation to singular identity politics or rights‐restraining institutions. Specifically, we point to transnational and Third World‐based queer movements that offer more complex structural analyses of sexual oppression as well as more visionary praxes of sexual rights. Drawing on lessons from two cases of queer human rights praxis from the Philippines and México, we assert that a queer grassroots enactment of human rights allows for multiple subaltern constituencies to find – and to make – a place in human rights discourses; queer identity and actions create social formations that expand human rights agendas to further embody the intersectionality, interdependence and transnationality of daily life. Key to these enactments of queer human rights praxis are prefigurative politics and rooted cosmopolitanism, which catalyze new expansions of human rights to include intersectional framings and practices of erotic justice.
Racist Nativism in the 21st Century
Authors: Lippard Cameron D. 
Published: July 2011

AbstractSince the 1960s, academia and the public have frequently used racism as the catch‐all phrase to explain any racial or ethnic injustice identified in America. However, are the disparities domestic minorities face the same as those faced by immigrant minorities? For example, journalists have suggested that the various state immigration policies targeting Hispanic immigrants in the United States recently are as racist as the Jim Crow laws enacted decades ago. In this essay, I contend that while nativism and racism are kissing cousins, distinguishing and using these concepts may lend to more precise explanations of the issues many racial and ethnic minorities face who exist outside of the Black–White dichotomy that has traditionally characterized United States. To untangle these terms, I review recent scholarship to provide up‐to‐date definitions, as well as reintroduce the concept of ‘racist nativism’ to better explain the variability that characterizes racial or ethnic prejudice and discrimination in 21st century America.
The More Things Change, the More They Remain the Same?
Authors: Latshaw Beth A. 
Published: July 2011

AbstractSince the publication of Arlie Hochschild’s groundbreaking work,The Second Shift(1989), scholars have delineated and deliberated the predictors and implications of American men’s participation in unpaid labor. Still, there’s little consensus about the current or future state of gender inequality in US households. In the course of reviewing scholarship published on this topic over the last two decades, this piece outlines and critically reflects upon two paradoxical conclusions one might reach when examining trends in men’s housework and care work time. In comparing and contrasting what I call ‘the mop bucket is half full’ and ‘the mop bucket is half empty’ conclusions, I also highlight the major theoretical frameworks, empirical findings, and diverging opinions on whether Hochschild’s ‘household revolution’ is permanently stalled, slowly reigniting, or ready to take off. I then conclude with a call for consensus among scholars and suggestions for future research on men’s participation in unpaid labor.
Reproductive performance of alternative male phenotypes of growth hormone transgenic Atlantic salmon (Salmo salar)
Authors: Moreau Darek T. R. , Conway Corinne , Fleming Ian A. 
Published: July 2011

AbstractGrowth hormone (GH) transgenic Atlantic salmon (Salmo salar) is one of the first transgenic animals being considered for commercial farming, yet ecological and genetic concerns remain should they enter the wild and interact reproductively with wild fish. Here, we provide the first empirical data reporting on the breeding performance of GH transgenic Atlantic salmon males, including that of an alternative male reproductive phenotype (i.e. small, precocially mature parr), in pair‐wise competitive trials within a naturalised stream mesocosm. Wild anadromous (i.e. large, migratory) males outperformed captively reared transgenic counterparts in terms of nest fidelity, quivering frequency and spawn participation. Similarly, despite displaying less aggression, captively reared nontransgenic mature parr were superior competitors to their transgenic counterparts in terms of nest fidelity and spawn participation. Moreover, nontransgenic parr had higher overall fertilisation success than transgenic parr, and their offspring were represented in more spawning trials. Although transgenic males displayed reduced breeding performance relative to nontransgenics, both male reproductive phenotypes demonstrated the ability to participate in natural spawning events and thus have the potential to contribute genes to subsequent generations.
DNA barcoding of the recently evolved genus Holcoglossum (Orchidaceae: Aeridinae): a test of DNA barcode candidates

Published: July 2011

AbstractOrchidaceae is one of the largest families of flowering plants. Many species of orchid are endangered, and all species are included in Conventions on International Trade of Endangered Species of Fauna and Flora (CITES) I and II, but it is very difficult to identify orchid species, even those with fertile parts. The genus Holcoglossum (Orchidaceae: Aeridinae) has long been problematic in taxonomy. It consists of both long‐evolved and radiated species and is an excellent case to use for testing DNA barcodes for Orchidaceae. We investigated the power of a subset of proposed plant barcoding loci [rbcL, matK, atpF‐atpH, psbK‐psbI, trnH‐psbA and internal transcribed spacer (ITS)] to discriminate between species in this genus. Our results showed that all these DNA regions, except psbK‐psbI and atpF‐atpH, can be amplified easily from Holcoglossum and sequenced with established primers. The DNA regions matK and ITS had the highest variability. Among the six loci, matK resolved eight of the 12 Holcoglossum species and had the highest discriminatory ability. However, the combination of matK and ITS showed a greater ability to identify species than matK alone. Single or combined DNA markers discriminated between Holcoglossum species distributed in tropical areas effectively, but had less ability to identify radiated species from the temperate Hengduan Mountains of China. In the study, matK proved to be a useful DNA barcode for the genus Holcoglossum; however, complementary DNA regions are still required to accelerate the investigation and preservation of radiated species of orchid.
Comparison of Growth Rates of Aerobic Anoxygenic Phototrophic Bacteria and Other Bacterioplankton Groups in Coastal Mediterranean Waters

Published: July 2011

ABSTRACT

Growth is one of the basic attributes of any living organism. Surprisingly, the growth rates of marine bacterioplankton are only poorly known. Current data suggest that marine bacteria grow relatively slowly, having generation times of several days. However, some bacterial groups, such as the aerobic anoxygenic phototrophic (AAP) bacteria, have been shown to grow much faster. Two manipulation experiments, in which grazing, viruses, and resource competition were reduced, were conducted in the coastal Mediterranean Sea (Blanes Bay Microbial Observatory). The growth rates of AAP bacteria and of several important phylogenetic groups (the
Bacteroidetes
, the alphaproteobacterial groups
Roseobacter
and SAR11, and the
Gammaproteobacteria
group and its subgroups the
Alteromonadaceae
and the NOR5/OM60 clade) were calculated from changes in cell numbers in the manipulation treatments. In addition, we examined the role that top-down (mortality due to grazers and viruses) and bottom-up (resource availability) factors play in determining the growth rates of these groups. Manipulations resulted in an increase of the growth rates of all groups studied, but its extent differed largely among the individual treatments and among the different groups. Interestingly, higher growth rates were found for the AAP bacteria (up to 3.71 day
−1
) and for the
Alteromonadaceae
(up to 5.44 day
−1
), in spite of the fact that these bacterial groups represented only a very low percentage of the total prokaryotic community. In contrast, the SAR11 clade, which was the most abundant group, was the slower grower in all treatments. Our results show that, in general, the least abundant groups exhibited the highest rates, whereas the most abundant groups were those growing more slowly, indicating that some minor groups, such the AAP bacteria, very likely contribute much more to the recycling of organic matter in the ocean than what their abundances alone would predict.
Geographic Distribution of Secondary Metabolite Genes in the Marine Actinomycete Salinispora arenicola

Published: July 2011

ABSTRACT

The molecular fingerprinting technique terminal-restriction fragment length polymorphism (T-RFLP) was used in combination with sequence-based approaches to evaluate the geographic distribution of secondary metabolite biosynthetic genes in strains of the marine actinomycete
Salinispora arenicola
. This study targeted ketosynthase (KS) domains from type I polyketide synthase (PKS) genes and revealed four distinct clusters, the largest of which was comprised of strains from all six global locations sampled. The remaining strains fell into three smaller clusters comprised of strains derived entirely from the Red Sea, the Sea of Cortez, or around the Island of Guam. These results reveal variation in the secondary metabolite gene collectives maintained by strains that are largely clonal at the 16S rRNA level. The location specificities of the three smaller clusters provide evidence that collections of secondary metabolite genes in subpopulations of
S. arenicola
are endemic to these locations. Cloned KS sequences support the maintenance of distinct sets of biosynthetic genes in the strains associated with each cluster and include four that had not previously been detected in
S. arenicola
. Two of these new sequences were observed only in strains derived from Guam or the Sea of Cortez. Transcriptional analysis of one of the new KS sequences in conjunction with the production of the polyketide arenicolide A supports a link between this sequence and the associated biosynthetic pathway. From the perspective of natural product discovery, these results suggest that screening populations from distant locations can enhance the discovery of new natural products and provides further support for the use of molecular fingerprinting techniques, such as T-RFLP, to rapidly identify strains that possess distinct sets of biosynthetic genes.

ABSTRACT

Baeyer-Villiger monooxygenases catalyze oxidations that are of interest for biocatalytic applications. Among these enzymes, phenylacetone monooxygenase (PAMO) from
Thermobifida fusca
is the only protein showing remarkable stability. While related enzymes often present a broad substrate scope, PAMO accepts only a limited number of substrates. Due to the absence of a substrate in the elucidated crystal structure of PAMO, the substrate binding site of this protein has not yet been defined. In this study, a structural model of cyclopentanone monooxygenase, which acts on a broad range of compounds, has been prepared and compared with the structure of PAMO. This revealed 15 amino acid positions in the active site of PAMO that may account for its relatively narrow substrate specificity. We designed and analyzed 30 single and multiple mutants in order to verify the role of these positions. Extensive substrate screening revealed several mutants that displayed increased activity and altered regio- or enantioselectivity in Baeyer-Villiger reactions and sulfoxidations. Further substrate profiling resulted in the identification of mutants with improved catalytic properties toward synthetically attractive compounds. Moreover, the thermostability of the mutants was not compromised in comparison to that of the wild-type enzyme. Our data demonstrate that the positions identified within the active site of PAMO, namely, V54, I67, Q152, and A435, contribute to the substrate specificity of this enzyme. These findings will aid in more dedicated and effective redesign of PAMO and related monooxygenases toward an expanded substrate scope.

ABSTRACT

Soil microbial community characterization is increasingly being used to determine the responses of soils to stress and disturbances and to assess ecosystem sustainability. However, there is little experimental evidence to indicate that predictable patterns in microbial community structure or composition occur during secondary succession or ecosystem restoration. This study utilized a chronosequence of developing jarrah (
Eucalyptus marginata
) forest ecosystems, rehabilitated after bauxite mining (up to 18 years old), to examine changes in soil bacterial and fungal community structures (by automated ribosomal intergenic spacer analysis [ARISA]) and changes in specific soil bacterial phyla by 16S rRNA gene microarray analysis. This study demonstrated that mining in these ecosystems significantly altered soil bacterial and fungal community structures. The hypothesis that the soil microbial community structures would become more similar to those of the surrounding nonmined forest with rehabilitation age was broadly supported by shifts in the bacterial but not the fungal community. Microarray analysis enabled the identification of clear successional trends in the bacterial community at the phylum level and supported the finding of an increase in similarity to nonmined forest soil with rehabilitation age. Changes in soil microbial community structure were significantly related to the size of the microbial biomass as well as numerous edaphic variables (including pH and C, N, and P nutrient concentrations). These findings suggest that soil bacterial community dynamics follow a pattern in developing ecosystems that may be predictable and can be conceptualized as providing an integrated assessment of numerous edaphic variables.
