What Psychoanalysis, Culture And Society Mean To Me

Layton, Lynne

2007-01-01

The paper reviews some ways that the social and psychic have been understood in psychoanalysis and argues that a model for understanding the relation between the psychic and the social must account both for the ways that we internalize oppressive norms as well as the ways we resist them. The author proposes that we build our identities in relation to other identities circulating in our culture and that cultural hierarchies of sexism, racism, classism push us to split off part of what it means to be human, thereby creating painful individual and relational repetition compulsions. These “normative unconscious processes” replicate the unjust social norms that cause psychic pain in the first place. The paper concludes with thoughts about contemporary US culture, in which the government has abdicated responsibility toward its most vulnerable citizens and has thus rendered vulnerability and dependence shameful states.

When means become ends: technology producing values

Bjørn Hofmann

Full Text Available Technology has become the symbol of our culture.  The claim that we are subject to a technological imperative is therefore a fundamental cultural critique: we do not control technology, rather technology controls us. An alternative way to formulate this is to claim that technology cannot be “made down” when it is made up; we just have to make the best of it. Accordingly, it has been argued that technology has evolved from being merely a means to becoming an end in itself. This article investigates this claim by analyzing the relationship between technology and values. The examples stem from the technologies of medicine and weapons because they clarify this relationship. It is argued that technology relates to values in two ways. Technology both raises general questions about values and it is value-laden due to its very function. However, although technology is value-laden, it does not necessarily give an imperative mandate. One reason for this lies in our responsibility. We are inevitably responsible for all aspects of technology, i.e. development, construction, production, commercialization, implementation, and use. Referring to a technological imperative to explain and defend our decisions with respect to technology constitutes an unjustified renunciation of our own responsibility. Hence, the article tries to underscore our responsibility by developing a technological axiology.

Full Text Available Abstract Commonly, an amazing and attractive advertisement intends to hypnotize their target consumer in seeing, reading, or even hearing the ads continually. Besides, the power of persuading and motivating in messages from the way of informing product benefit could also give impact to buyer in deciding to buy the product. This research discusses the contexts of advertising found on packages of two Nestle products, especially Nestle Dancow Actigo and Nestle Dancow Enrich. These products were analyzed based on pictures or symbols and text found on packages. It is aimed at finding out the context of discourse advertising on those packages. Data were collected from analysis of text, including pictures or symbols and additional questionnaires distributed to 50 respondents located at Denpasar and Gianyar. Urban society were used to evaluate concerning on their understanding of English even though Indonesian language mostly applied on packages of products. Method used in analyzing data is descriptive qualitative and quantitative with simple statistics and explanation. It showed that connotation and denotation meanings highlighted lexical items and its cultural adaptation using process of copy adaptation to fit the culture of their targeted consumers. Means found 6 words or phrases of English from 10 of them on packages understood by 50 respondents as of: 35 for Full Cream as highest score and 16 respondents for FortiGro as the lowest score. In addition, brand name, symbol and images showed producer seemed to have close relationship with consumer and able to attract target   consumer attention as majority of findings. It can be concluded that ads on packages of Nestle Dancow had succeeded to be understood by the society through the messages implied.

Emotions in “the world”: cultural practices, products, and meanings of anger and shame in two individualist cultures

Boiger, Michael; Deyne, Simon De; Mesquita, Batja

2013-01-01

Three studies tested the idea that people’s cultural worlds are structured in ways that promote and highlight emotions and emotional responses that are beneficial in achieving central goals in their culture. Based on the idea that U.S. Americans strive for competitive individualism, while (Dutch-speaking) Belgians favor a more egalitarian variant of individualism, we predicted that anger and shame, as well as their associated responses, would be beneficial to different extents in these two cultural contexts. A questionnaire study found that cultural practices promote beneficial emotions (anger in the United States, shame in Belgium) and avoid harmful emotions (shame in the United States): emotional interactions were perceived to occur more or less frequently to the extent that they elicited culturally beneficial or harmful emotions. Similarly, a cultural product analysis showed that popular children’s books from the United States and Belgium tend to portray culturally beneficial emotions more than culturally harmful emotions. Finally, a word-association study of the shared cultural meanings surrounding anger and shame provided commensurate evidence at the level of the associated response. In each language network, anger and shame were imbued with meanings that reflected the cultural significance of the emotion: while culturally consistent emotions carried relatively stronger connotations of emotional yielding (e.g., giving in to anger and aggressing against the offender in the United States), culturally inconsistent emotions carried relatively stronger connotations of emotional containment (e.g., a stronger emphasis on suppressing or transforming shame in the United States).

Is the Appropriateness of Emotions Culture-Dependent? The Relevance of Social Meaning

Directory of Open Access Journals (Sweden)

Welpinghus Anna

2018-02-01

Full Text Available This paper contributes to the question to what extent the socio-cultural context is relevant for the appropriateness of emotions, while appropriateness of an emotion means that the emotion entails a correct, or adequate, evaluation of its object. In a first step, two adequacy conditions for theories of emotions are developed: the first condition ensures that the socio-cultural context is not neglected: theories must allow for the fact that appropriateness often depends on the social meaning of the emotion’s particular object. The second condition rules out implausible forms of cultural determinism. In a second step, an account that meets both conditions is presented: the Acceptance within Social Context account.

NMR studies of post-translationally modified proteins are complicated by the lack of an efficient method to produce isotope enriched recombinant proteins in cultured mammalian cells. We show that reducing the glucose concentration and substituting glutamate for glutamine in serum-free medium increased cell viability while simultaneously increasing recombinant protein yield and the enrichment of non-essential amino acids compared to culture in unmodified, serum-free medium. Adding dichloroacetate, a pyruvate dehydrogenase kinase inhibitor, further improves cell viability, recombinant protein yield, and isotope enrichment. We demonstrate the method by producing partially enriched recombinant Thy1 glycoprotein from Lec1 Chinese hamster ovary (CHO) cells using U-{sup 13}C-glucose and {sup 15}N-glutamate as labeled precursors. This study suggests that uniformly {sup 15}N,{sup 13}C-labeled recombinant proteins may be produced in cultured mammalian cells starting from a mixture of labeled essential amino acids, glucose, and glutamate.

Full Text Available Based on three key psychological concepts: learning, culture and meaning, the present essay proposes a conceptualbase frame, oriented toward the understanding of development in organizations into current milieu ofcompetitiveness and temporality, of the relationships among people working into them. The organizations whichare typically embedded in a context of values, needs and symbols that made up their cultures, must evolve in orderto face the demands for new developments and change, to which they are forced to. The concept of “meaning of theculture”, is presented as the base over which is build and rooted the organizational learning - in a technical and socialsense. The different types of learning are the ways in which the organizations satisfy the requirements coming fromtheir environments, in front of which must generate knowledge and consequently, new products and services,based on the people that form such organizations. The people that belong and constitutes the organization, incircumstances of temporal cohesion and within temporary working networks, must achieve results and to beadjusted to these new working and organizational facts, developing self-management and autonomy, in order tosignify and get adapted into the cultural tissue.

Biological production of hydrogen (H2) and polyhydroxybutyrate (PHB) from pea-shell slurry (PSS) was investigated using defined mixed culture (MMC4, composed of Enterobacter, Proteus, Bacillus spp.). Under batch culture, 19.0LH2/kg of PSS (total solid, TS, 2%w/v) was evolved. Using effluent from the H2 producing stage, Bacillus cereus EGU43 could produce 12.4% (w/w) PHB. Dilutions of PSS hydrolysate containing glucose (0.5%, w/v) resulted in 45-75LH2/kg TS fed and 19.1% (w/w) of PHB content. Under continuous culture, MMC4 immobilized on coconut coir (CC) lead to an H2 yield of 54L/kg TS fed and a PHB content of 64.7% (w/w). An improvement of 2- and 3.7-fold in H2 and PHB yields were achieved in comparison to control. This integrative approach using defined set of bacterial strains can prove effective in producing biomolecules from biowastes. Copyright © 2014. Published by Elsevier Ltd.

Of Models and Meanings: Cultural Resilience in Social-Ecological Systems

Directory of Open Access Journals (Sweden)

Todd A. Crane

2010-12-01

Full Text Available Modeling has emerged as a key technology in analysis of social-ecological systems. However, the tendency for modeling to focus on the mechanistic materiality of biophysical systems obscures the diversity of performative social behaviors and normative cultural positions of actors within the modeled system. The fact that changes in the biophysical system can be culturally constructed in different ways means that the perception and pursuit of adaptive pathways can be highly variable. Furthermore, the adoption of biophysically resilient livelihoods can occur under conditions that are subjectively experienced as the radical transformation of cultural systems. The objectives of this work are to: (1 highlight the importance of understanding the place of culture within social-ecological systems, (2 explore the tensions between empirical and normative positions in the analysis of social-ecological resilience, and (3 suggest how empirical modeling of social-ecological systems can synergistically interact with normative aspects of livelihoods and lifeways.

Development of brain function is critically dependent on neuronal networks organized through three dimensions. Culture of central nervous system neurons has traditionally been limited to two dimensions, restricting growth patterns and network formation to a single plane. Here, with the use of multichannel extracellular microelectrode arrays, we demonstrate that neurons cultured in a true three-dimensional environment recapitulate native neuronal network formation and produce functional outcomes more akin to in vivo neuronal network activity.

The description and interpretation of material culture may be regarded as the essence of archaeology, a discipline that seeks to recover, describe, document, and interpret past human culture. More recently, understanding that actions occur in a material world that is constituted symbolically, archaeological explanations are often framed in sociocultural meanings, the analysis of agencies, practices and behaviors. I shall subsequently return to this issue. Because of their longevity in the archaeological record, lithic and ceramic artifacts are crucial to the endeavor to interpret human culture. Objects fashioned from clay and subjected to intentional artificial sources of heat made their initial appearance in the archaeological record more than 26.000 years ago. Ceramic objects have been created in a seemingly endless variety of shapes and forms, varying from fertility figurines. to cooking and food storage vessels. lamps, smoking pipes, medicinal pastilles, tokens, beehives, and coffins to modern whitewares and pyroceramics.

Biomass recycle as a means to improve the energy efficiency of CELSS algal culture systems

Science.gov (United States)

Radmer, R.; Cox, J.; Lieberman, D.; Behrens, P.; Arnett, K.

1987-01-01

Algal cultures can be very rapid and efficient means to generate biomass and regenerate the atmosphere for closed environmental life support systems. However, as in the case of most higher plants, a significant fraction of the biomass produced by most algae cannot be directly converted to a useful food product by standard food technology procedures. This waste biomass will serve as an energy drain on the overall system unless it can be efficiently recycled without a significant loss of its energy content. Experiments are reported in which cultures of the alga Scenedesmus obliquus were grown in the light and at the expense of an added carbon source, which either replaced or supplemented the actinic light. As part of these experiments, hydrolyzed waste biomass from these same algae were tested to determine whether the algae themselves could be made part of the biological recycling process. Results indicate that hydrolyzed algal (and plant) biomass can serve as carbon and energy sources for the growth of these algae, suggesting that the efficiency of the closed system could be significantly improved using this recycling process.

An Empirical Model and Ethnic Differences in Cultural Meanings Via Motives for Suicide.

Chu, Joyce; Khoury, Oula; Ma, Johnson; Bahn, Francesca; Bongar, Bruce; Goldblum, Peter

2017-10-01

The importance of cultural meanings via motives for suicide - what is considered acceptable to motivate suicide - has been advocated as a key step in understanding and preventing development of suicidal behaviors. There have been limited systematic empirical attempts to establish different cultural motives ascribed to suicide across ethnic groups. We used a mixed methods approach and grounded theory methodology to guide the analysis of qualitative data querying for meanings via motives for suicide among 232 Caucasians, Asian Americans, and Latino/a Americans with a history of suicide attempts, ideation, intent, or plan. We used subsequent logistic regression analyses to examine ethnic differences in suicide motive themes. This inductive approach of generating theory from data yielded an empirical model of 6 cultural meanings via motives for suicide themes: intrapersonal perceptions, intrapersonal emotions, intrapersonal behavior, interpersonal, mental health/medical, and external environment. Logistic regressions showed ethnic differences in intrapersonal perceptions (low endorsement by Latino/a Americans) and external environment (high endorsement by Latino/a Americans) categories. Results advance suicide research and practice by establishing 6 empirically based cultural motives for suicide themes that may represent a key intermediary step in the pathway toward suicidal behaviors. Clinicians can use these suicide meanings via motives to guide their assessment and determination of suicide risk. Emphasis on environmental stressors rather than negative perceptions like hopelessness should be considered with Latino/a clients. © 2017 Wiley Periodicals, Inc.

Cellular modifications produced by D2O in yeast culture

International Nuclear Information System (INIS)

Mihancea, I.; Mircea, R.Al.

1996-01-01

The cellular cycle of the Saccharomyces Cerevisiae, chosen as experimental object, is unmodified by the presence in the culture medium of D 2 O at different concentrations. An increased concentration of D 2 O in the culture medium leads to a decrease of the number of budded cells, to metabolic alterations, to DNA structure modification as well as to enzymatic changes produced by blocking. Other anomalies appear, as a function of the cell defence capacity and of the influence of the factors from the nutrient substrate or exterior medium. Due to D 2 O, the medium's pH changes and modifications at the enzyme level and of the cell microstructure and morphology occur. The enzymatic reactions take place in D 2 O slower than in H 2 O. Three-dimensional modifications appear in the organic components of the live cell which, in turn, produce profound modifications in the cell growth and division. Due to the kinetic and isotopic effects, modifications of the biochemical reactions affecting the cell integrity happen

Eight out of 10 Mapuche indigenous women have a musculoskeletal disorder (MSD) and do not seek early medical aid. To study both the cultural meanings and implications of MSD from the Mapuche worldview. Ethnographic study carried out from 2008 to 2011 on indigenous reserves in southern Chile. Sixty-four Mapuches participated in comprehensive interviews, which were transcribed and analyzed by the research team. Five cultural domains: (a) foro kutran/bone disease is the general denomination of MSD; (b) Re-Rume Kutran/progressive and incurable course, refers to the course of the disease; (c) Kalül fücha mawiza/body is an old tree, describes internal manifestations such as worn bones, dry body, weak blood, and spiritual weakness; (d) witrür tripai foro/deformation is the external manifestation of MSD; and (e) Reñma ka lof kutran/family and community suffering refers to the impact of MSD. The explanation of MSD is consistent with the integrated body-nature-spirit worldview of the Mapuche. To provide cultural nursing health care so that patients receive prompt diagnosis and care.

Crossing the cultural divide: issues in translation, mistrust, and cocreation of meaning in cross-cultural therapeutic assessment.

Rosenberg, Audrey; Almeida, Angelica; Macdonald, Heather

2012-01-01

This article examines cross-cultural therapeutic assessment in a community mental health clinic. The first case describes the work between a Caucasian assessor and a Mexican American family. The authors explore the metaphorical and literal translation of the findings from English to Spanish and the parallel process of translation of the self, experienced by both assessor and client. The second case describes the work between a Caucasian assessor and an African American adolescent. We describe the inherent challenge between the Eurocentric "task" orientation of the evaluation and the Afrocentric "relationship" orientation. We suggest that bridging the gap between cultures and overcoming cultural mistrust lay in the building of the assessor-client relationship. Fischer's concepts of rapport and intimacy are emphasized and expanded on as we emphasize the importance of cocreated meaning in cross-cultural assessment work.

Clusters of cultures: diversity in meaning of family value and gender role items across Europe.

van Vlimmeren, Eva; Moors, Guy B D; Gelissen, John P T M

2017-01-01

Survey data are often used to map cultural diversity by aggregating scores of attitude and value items across countries. However, this procedure only makes sense if the same concept is measured in all countries. In this study we argue that when (co)variances among sets of items are similar across countries, these countries share a common way of assigning meaning to the items. Clusters of cultures can then be observed by doing a cluster analysis on the (co)variance matrices of sets of related items. This study focuses on family values and gender role attitudes. We find four clusters of cultures that assign a distinct meaning to these items, especially in the case of gender roles. Some of these differences reflect response style behavior in the form of acquiescence. Adjusting for this style effect impacts on country comparisons hence demonstrating the usefulness of investigating the patterns of meaning given to sets of items prior to aggregating scores into cultural characteristics.

Leininger's culture care diversity and universality theory, ethnonursing, and four-phase analysis method guided the study. Interviews were conducted with 19 general and 10 key informants. Analysis of interviews revealed three main themes: (a) family presence is essential for meaningful care experiences and care practices, (b) respect and attention are central to the meaning of care and care practices, and (c) rural Dominicans value and use both generic (folk) and professional care practices. Implications and recommendations for nursing practice, education, and research are described.

Bishnuprasad Rabha as Cultural Icon of Assam: The Process of Meaning Making

Directory of Open Access Journals (Sweden)

Parismita Hazarika

2017-03-01

Full Text Available Abstract The term ‘cultural icon’ is generally used to refer to individuals or images, objects, visual sign, monuments, space etc. In semiotics the term ‘icon’ is used to refer to a sign that bears close resemblance to the object that it stands for. Icons are particularly influential signifiers because they are immediately identifiable and carry complex cultural codes in a compact image. In this paper the understanding of ‘cultural icon’ is not limited to semiotics. Following Keyan Tomaselli and David Scott in Cultural Icons (2009, we believe that cultural icons are purposive constructions. An attempt has been made in this paper to analyze the association of ‘desirable’ meanings to a cultural icon (while dropping ‘undesirable’ ones; thus, it is imperative that we look at the changing socio-political contexts behind such purposive constructions. With this in mind, we look at the iconic figure of Bishnuprasad Rabha who has been one of the most revered figures in the cultural history of Assam and has been appropriated as a cultural icon in different discourses of the national life of Assam that has emerged in recent times.

Children's activities and their meanings for parents: a mixed-methods study in six Western cultures.

Theoretical perspectives and research in sociology, anthropology, sociolinguistics, and cultural psychology converge in recognizing the significance of children's time spent in various activities, especially in the family context. Knowing how children's time is deployed, however, only gives us a partial answer to how children acquire competence; the other part must take into account the culturally constructed meanings of activities, from the perspective of those who organize and direct children's daily lives. In this article, we report on a study of children's routine daily activities and on the meanings that parents attribute to them in six Western middle-class cultural communities located in Italy, The Netherlands, Poland, Spain, Sweden, and the United States (N = 183). Using week-long time diaries kept by parents, we first demonstrate similarities as well as significant differences in children's daily routines across the cultural samples. We then present brief vignettes--"a day in the life" --of children from each sample. Parent interviews were coded for themes in the meanings attributed to various activities. Excerpts from parent interviews, focusing on four major activities (meals, family time, play, school- or developmentally related activities), are presented to illustrate how cultural meanings and themes are woven into parents' organization and understanding of their children's daily lives. The results of this mixed-method approach provide a more reliable and nuanced picture of children's and families' daily lives than could be derived from either method alone.

Resveratrol Produces Neurotrophic Effects on Cultured Dopaminergic Neurons through Prompting Astroglial BDNF and GDNF Release

Directory of Open Access Journals (Sweden)

Feng Zhang

2012-01-01

Full Text Available Increasing evidence indicated astroglia-derived neurotrophic factors generation might hold a promising therapy for Parkinson’s disease (PD. Resveratrol, naturally present in red wine and grapes with potential benefit for health, is well known to possess a number of pharmacological activities. Besides the antineuroinflammatory properties, we hypothesized the neuroprotective potency of resveratrol is partially due to its additional neurotrophic effects. Here, primary rat midbrain neuron-glia cultures were applied to investigate the neurotrophic effects mediated by resveratrol on dopamine (DA neurons and further explore the role of neurotrophic factors in its actions. Results showed resveratrol produced neurotrophic effects on cultured DA neurons. Additionally, astroglia-derived neurotrophic factors release was responsible for resveratrol-mediated neurotrophic properties as evidenced by the following observations: (1 resveratrol failed to exert neurotrophic effects on DA neurons in the cultures without astroglia; (2 the astroglia-conditioned medium prepared from astroglia-enriched cultures treated with resveratrol produced neurotrophic effects in neuron-enriched cultures; (3 resveratrol increased neurotrophic factors release in the concentration- and time-dependent manners; (4 resveratrol-mediated neurotrophic effects were suppressed by blocking the action of the neurotrophic factors. Together, resveratrol could produce neurotrophic effects on DA neurons through prompting neurotrophic factors release, and these effects might open new alternative avenues for neurotrophic factor-based therapy targeting PD.

The Cultural Voice of Immigrant Latina Women and the Meaning of Femininity

Directory of Open Access Journals (Sweden)

Ellen Greer

2013-04-01

Full Text Available This phenomenological study investigates the cultural meaning of femininity to immigrant Latina women and its significance in the consideration of decisions related to maintaining breast health. Theories of culture and health promotion support the concern for women’s need for access to health care in relation to breast health and the cultural barriers that interface between the connections of femininity, body image, and mental health. For Hispanic women, breast cancer is the most commonly diagnosed cancer generating distress for the individual, partner, and family. The importance of best practices in health promotion and risk reduction strategies in the early screening of women is emphasized in the literature. However, the voice of immigrant Latina women in describing their perspective of femininity and breast health and how it may affect choice and decision making related to breast self-care practices has not been studied. Five themes emerged from the data analysis conducted with Giorgi’s phenomenological method leading to an unfolded description of femininity: power of feminine identity through motherhood, hardiness is sustainability to overcoming adversity, connection to self and others, satisfaction meeting cultural gender-role expectations, and contemplative prevention to maintain breast integrity. The findings of this study will contribute to the increasing body of evidence-based practice related to understanding the impact of culture related to breast health. While the concept of femininity can be challenged not only by a diagnosis of breast cancer but also by other diseases and life conditions, understanding the cultural meaning of femininity to Latina women is pivotal to health care professionals as they partner with Latina women and community support groups to develop empowerment strategies and programs that promote choice and decision making involving breast health.

Full Text Available Danièle Hervieu-Léger gives an account of religion as a chain of memory, that is, a form of collective memory and imagination based on the sanctity of tradition. According to her theory, in the postmodern world the continuity of religious memory has been broken and all that remains are isolated fragments guarded by religious groups. This twofold study aims at showing, firstly, in what sense religion can be conceived of as memory which produces collective meanings (Part One and, secondly, what may happen when individualised and absolutised memories alienate themselves from a continuity of tradition, thus beginning to function as a sort of private religion (Part Two. Being the first part of the study in question, this article is dedicated to a historical-theological analysis of religious memory as a source of collective meanings, as seen from a Christian perspective. Firstly, it situates Hervieu-Léger’s definition of religion against the background of the most topical religious contexts in which the notion of memory appears today. Secondly, the dialectics of individual and collective memory is discussed, notably through the lens of Ricoeur’s original proposal. This is followed by an overview of the traditional functions of memory in Christianity. Lastly, the interpretation of the way in which Christian tradition, in its premodern continuity, served as a source of collective cultural meanings, is recapitulated. What underlies this analysis is the conviction that to comprehend, and even more so to challenge mechanisms based on which the dominant purveyors of meaning (such as economic and information market function in our day, one should have a clear understanding of what they attempt to substitute for. In brief, before exploring how memories become religion, one ought to be able to conceive of religion as memory.

Culture care meanings and experiences of postpartum depression among Jordanian Australian women: a transcultural study.

Science.gov (United States)

Nahas, V; Amasheh, N

1999-01-01

This study discovers, describes, and explains the personal experiences, perceptions, and care meanings of Jordanian women who have suffered postpartum depression. Most postpartum cases often are misdiagnosed as exclusively psychological and untreated by health care professionals without consideration to the cultural meanings of this problem. Understanding the experiences of these women is important, as their expressions often are contextually and culturally influenced. Using Leininger's Theory of Culture Care Diversity and Universality, a purposive sample of 22 Jordanian women diagnosed with postpartum depression, living in Sydney, were interviewed. The ethnonursing research method and data analysis procedures were used. Results revealed that Jordanian mothers experienced severe loss of control over emotions of loneliness, hopelessness, and feelings of being a bad mother. Three major themes focusing on the care meanings and experiences of Jordanian women are discussed: (a) Care means strong family support and kinship during the postpartum period, (b) care is carrying out and fulfilling traditional gender roles as mother and wife, and (c) care is preservation of Jordanian childbearing customs as expressed in the celebration of the birth of the baby.

Soil and saline water samples were collected from the Daishan Saltern of East China, and the halophilic bacteria were isolated and cultured by using selective media, aimed to investigate the diversity and enzyme-producing activity of culturable halophilic bacteria in saltern environment. A total of 181 strains were isolated by culture-dependent method. Specific primers were used to amplify the 16S rRNA gene of bacteria and archaea. The operation taxonomy units (OTUs) were determined by ARDRA method, and the representative strain of each OTU was sequenced. The phylogenetic position of all the isolated strains was determined by 16S rRNA sequencing. The results showed that the isolated 181 strains displayed 21 operational taxonomic units (OTUs), of which, 12 OTUs belonged to halophilic bacteria, and the others belonged to halophilic archaea. Phylogenetic analysis indicated that there were 7 genera presented among the halophilic bacteria group, and 4 genera presented among the halophilic archaea group. The dominant halophilic strains were of Halomonas and Haloarcula, with 46.8% in halophilic bacteria and 49.1% in halophilic archaea group, respectively. Enzyme-producing analysis indicated that most strains displayed enzyme-producing activity, including the activities of producing amylase, proteinase and lipase, and the dominant strains capable of enzyme-producing were of Haloarcula. Our results showed that in the environment of Daishan Saltern, there existed a higher diversity of halophilic bacteria, being a source sink for screening enzyme-producing bacterial strains.

Experiments with a First Prototype of a Spatial Model of Cultural Meaning through Natural-Language Human-Robot Interaction

Full Text Available When using assistive systems, the consideration of individual and cultural meaning is crucial for the utility and acceptance of technology. Orientation, communication and interaction are rooted in perception and therefore always happen in material space. We understand that a major problem lies in the difference between human and technical perception of space. Cultural policies are based on meanings including their spatial situation and their rich relationships. Therefore, we have developed an approach where the different perception systems share a hybrid spatial model that is generated by artificial intelligence—a joint effort by humans and assistive systems. The aim of our project is to create a spatial model of cultural meaning based on interaction between humans and robots. We define the role of humanoid robots as becoming our companions. This calls for technical systems to include still inconceivable human and cultural agendas for the perception of space. In two experiments, we tested a first prototype of the communication module that allows a humanoid to learn cultural meanings through a machine learning system. Interaction is achieved by non-verbal and natural-language communication between humanoids and test persons. This helps us to better understand how a spatial model of cultural meaning can be developed.

Ammonia produced by bacterial colonies promotes growth of ampicillin-sensitive Serratia sp. by means of antibiotic inactivation.

Science.gov (United States)

Cepl, Jaroslav; Blahůšková, Anna; Cvrčková, Fatima; Markoš, Anton

2014-05-01

Volatiles produced by bacterial cultures are known to induce regulatory and metabolic alterations in nearby con-specific or heterospecific bacteria, resulting in phenotypic changes including acquisition of antibiotic resistance. We observed unhindered growth of ampicillin-sensitive Serratia rubidaea and S. marcescens on ampicillin-containing media, when exposed to volatiles produced by dense bacterial growth. However, this phenomenon appeared to result from pH increase in the medium caused by bacterial volatiles rather than alterations in the properties of the bacterial cultures, as alkalization of ampicillin-containing culture media to pH 8.5 by ammonia or Tris exhibited the same effects, while pretreatment of bacterial cultures under the same conditions prior to antibiotic exposure did not increase ampicillin resistance. Ampicillin was readily inactivated at pH 8.5, suggesting that observed bacterial growth results from metabolic alteration of the medium, rather than an active change in the target bacterial population (i.e. induction of resistance or tolerance). However, even such seemingly simple mechanism may provide a biologically meaningful basis for protection against antibiotics in microbial communities growing on semi-solid media. © 2014 Federation of European Microbiological Societies.

Quantitative and qualitative research across cultures and languages: cultural metrics and their application.

Science.gov (United States)

Wagner, Wolfgang; Hansen, Karolina; Kronberger, Nicole

2014-12-01

Growing globalisation of the world draws attention to cultural differences between people from different countries or from different cultures within the countries. Notwithstanding the diversity of people's worldviews, current cross-cultural research still faces the challenge of how to avoid ethnocentrism; comparing Western-driven phenomena with like variables across countries without checking their conceptual equivalence clearly is highly problematic. In the present article we argue that simple comparison of measurements (in the quantitative domain) or of semantic interpretations (in the qualitative domain) across cultures easily leads to inadequate results. Questionnaire items or text produced in interviews or via open-ended questions have culturally laden meanings and cannot be mapped onto the same semantic metric. We call the culture-specific space and relationship between variables or meanings a 'cultural metric', that is a set of notions that are inter-related and that mutually specify each other's meaning. We illustrate the problems and their possible solutions with examples from quantitative and qualitative research. The suggested methods allow to respect the semantic space of notions in cultures and language groups and the resulting similarities or differences between cultures can be better understood and interpreted.

An approach of acidification was examined on formation of hydrogen-producing granules and biofilms in upflow column-shaped reactors. The reactors were fed with synthetic glucose wastewater and operated at 37 C and pH 5.5. The acclimated anaerobic culture was inoculated in four reactors designated R1, R2, R3 and R4, with R3 and R4 filled with granular activated carbon as support medium. To unveil the roles of acidification, microbial culture in R2 and R3 was subject to an acid incubation for 24 h by shifting the culture pH from 5.5 to 2.0. The experimental results suggested that the acidification substantially accelerated microbial granulation, but not biofilm formation. Microbial activities were inhibited by the acid incubation for about 78 h, resulting in the retarded formation of biofilms of the acidified culture. Reducing culture pH resulted in improvement in cell surface physicochemical properties favoring microbial adhesion and immobilization. Zeta potential increased from -25.3 mV to 11.9 mV, hydrophobicity in terms of contact angle improved from 31 to 38 and production of extracellular polymers increased from 66 mg/g-VSS to 136 mg/g-VSS. As a result of the formation of granules and biofilms, high hydrogen production rates of 6.98 and 7.49 L/L h were achieved in granule-based and biofilm-based reactors, respectively. It is concluded that acid incubation is an efficient means to initiate the rapid formation of granules by regulating the surface characteristics of microbial culture. The use of support media as starting nuclei may result in rapid formation of biofilms without the acidification. (author)

Full Text Available The article is devoted to the problem of socio-cultural competence formation by means of translation / interpretation and the necessity of foreign language communicative competence formation in the process of inclusive education. The question of training of young generation for life in a multi-ethnic and multicultural society, forming skills of communication and cooperation with people of different nationalities, the foreign language learning, the formation of the communicative and socio-cultural competence is one of the main tasks of modern school to meet educational needs persons with disabilities. Today’s realities require that students with special educational needs should study a foreign language and use it in the process of learning. In turn, the use of translation in the process of learning a foreign language helps students to get new skills, to form general and specific competences, including socio-cultural competence, which promotes socialization of children with special needs, and integrating them into a comprehensive system of Ukraine. The article raises the problem of modernization of the educational system. It was established that the formation of socio-cultural competence by means of written translation is done by means of a system of exercises. Based on this system, subsystems, groups and types of exercises their systems can be developed in accordance with human activity, objectives and learning environment. It shows that the development of an inclusive approach to learning demands new solutions towards learning a foreign language at different levels of education.

Defining the site preference of nitrous oxide (N2O) produced in pure culture studies is crucial to interpreting field data. We have previously demonstrated that the intramolecular distribution of nitrogen isotopes (isotopomers) can be used to differentiate N2O produced by nitrifier denitrification and nitrification in cultures of Nitrosomonas europaea. Here, we have expanded on our initial results and evaluated the isotopomeric composition of N2O produced during nitrification and nitrifier denitrification with cultures of Nitrosospira multiformis. In addition, we have analyzed N2O produced during methanotrophic nitrification, denitrification, and fungal denitrification. To evaluate N2O production during nitrification and nitrifier denitrification, we compared the site preference of N2O formed as a result of nitrite reduction and hydroxylamine oxidation with Nitrosomonas europaea and Nitrosospira multiformis. The average site preference of N2O produced by hydroxylamine oxidation was similar for Nitrosomonas europaea (33.0 ± 3.5 ‰ ) and Nitrosospira multiformis (33.1 ± 4.2 ‰ ). Nitrous oxide produced by nitrifier-denitrification by Nitrosomonas europaea and Nitrosospira multiformis had a similar site preference of - 1.4 ± 4.4 ‰ and - 1.1 ± 2.6 ‰ respectively. The results indicate that it is possible to differentiate between N2O produced by nitrite reduction and hydroxylamine oxidation by ammonia oxidizing bacteria. Methanotrophic nitrification was evaluated by analyzing the N2O produced during hydroxylamine oxidation in concentrated cell suspensions of two methane oxidizing bacteria. The site preference of N2O produced by the two methane oxidizers, Methylococcus capsulatus Bath and Methylosinus trichosporium was 31.8 ± 4.7 ‰ and 33.0 ± 4.5 ‰ respectively. The results indicate that a site preference of 33 ‰ is applicable for nitrification regardless of whether a methane oxidizer or ammonia oxidizer is involved in the reaction. To determine the site

Translation and Culture:Translation as a Cross-cultural Mediation

Institute of Scientific and Technical Information of China (English)

叶谋锦

2013-01-01

Translation is a complex activity which involves language competence as well as proficiency in multiculturalism. From the perspective of multiculturalism, translation resembles recreation of source text by grasping essential meanings to produce a sub-tle target text which can be clearly perceived by target readers. Ignoring cultural issues can present serious mistranslations in the field of advertising translation. This paper aims to explore the significance of connotation confined by the framework of culture and point out that verbal translation is a dangerous inclination by illustrating three business examples. This paper argues that cross-cultural mediation plays an important role in translation.

The aim of this study was to evaluate the ability of bacterial cultures isolated from cattle, poultry or pig faeces and manure to produce rhamnolipids, as well as to investigate the influence of interspecies communication on possible quantitative differences in the production of rhamnolipid congeners. Initial screening methods (oil spreading, drop collapse, haemolytic activity and emulsification activity) showed that approximately 36% of the 51 isolated cultures exhibited the ability to produce biosurfactants. Subsequent studies using a selected culturable mixed culture (which included Enterococcus faecalis, Pseudomonas aeruginosa and Escherichia coli) revealed that only P. aeruginosa was able to produce this biosurfactant. HPLC-MS analysis showed that the surface active compounds were rhamnolipids. Further comparative studies confirmed that the total yield of rhamnolipids was notably higher in the bioreactor inoculated with the selected mixed culture (940.58±1.10mg/L) compared to the bioreactor inoculated with the axenic strain of P. aeruginosa (108.47±0.41mg/L). Twelve rhamnolipid congeners were identified during cultivation of the selected mixed culture, whereas six congeners were detected during cultivation of the sole axenic strain of P. aeruginosa. Furthermore, increased production of rhamnolipids was observed when the concentration of autoinducer molecules (AI-2) responsible for interspecies signaling increased, suggesting the influence of quorum-sensing communication on biosynthesis efficiency. This observation may be of importance for large-scale production of this biosurfactant, as it opens new possible solutions based on the use of mixed cultures or external addition of stimulating autoinducers.

2015-06-01

Full Text Available It discusses the meanings given by 14 physical education teachers about their experiences with the continued formation process. It is a (auto biographical narrative research, which used focal groups and interviews as tools for compiling the data. The colaborators are six male teachers and eight female teachers of municipal networks from Serra, Vitoria and Viana municipalities in the metropolitan region of Vitória, ES. The analyzes indicate that the assigned meanings are related to the collective need to reorganize institutional provided formations in dialogue with the political interests of teachers and the specificity of Physical Education as a curriculum component. In general, teachers consider the formation focused on practice and in the teaching profession as those that best reflect their expectations. The practice appears as a know-how to be appropriate from continued formetion to be experienced in school; a knowledge that, when apprehended, is reframed to produce other experiences.

The increasing frequency of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae is becoming a serious public health concern. This study sought to determine ESBL frequency in Enterobacteriaceae isolated from patients' blood cultures in two university teaching hospitals of Bamako, Mali. During a three-month period, the presence of Enterobacteriaceae from blood cultures of patients admitted to the university teaching hospitals of Bamako was evaluated. The microbial identifications were initially performed with an API 20E gallery and VITEK2 locally in Mali, and then confirmation in France was performed with a mass spectrometry MALDI-TOF in the bacteriology laboratory of the university teaching hospital of Bichat. Antibiotic susceptibility profiles were determined by the diffusion method as recommended by the European Committee on Antimicrobial Susceptibility Testing (EUCAST). The isolated species were K. pneumoniae (14/40; 35.0%), E. coli (11/40; 27.5%), and E. cloacae (9/40; 22.5%). Of the strains isolated, 21/34 (61.8%) had an ESBL phenotype, including 10/14 (71.4%) K. pneumoniae, 8/11 (72.7%) E. coli, and 3/9 (33.3%) E. cloacae. Resistances associated with ESBL strains of K. pneumoniae, E. coli, and E. cloacae were as follows: gentamicin (10/10, 100%; 6/8, 75%; 2/3, 67%, respectively), amikacin (2/10, 20%; 0/8, 0%; 0/3, 0%, respectively), ofloxacin (8/10, 80%; 7/8, 87%; 3/3, 100%, respectively), and cotrimoxazole (10/10, 100%; 6/8, 75%; 3/3, 100%, respectively). Almost two-thirds (61.8%) of Enterobacteriaceae isolated from our blood cultures were ESBL producers. Only susceptibilities to carbapenems and to amikacin were fully conserved within the strains.

When does meaning making predict subjective well-being? Examining young and older adults in two cultures.

Alea, Nicole; Bluck, Susan

2013-01-01

Two studies in different cultures (Study 1: USA, N=174, Study 2: Trinidad, N=167) examined whether meaning making, (i.e., both searching for meaning, and directing behaviour) is positively related to subjective well-being (SWB) by age (younger, older adults). In both studies, participants self-reported engagement in meaning making, and SWB (e.g., affect, future time perspective, psychological well-being). In Study 1, young Americans (compared to older) more frequently used their past to direct behaviour but doing so was unrelated to SWB. In older Americans, both types of meaning making were positively associated with SWB. In Study 2, Trinidadian younger adults were again more likely than older adults to engage in meaning making. Unlike in the American sample, however, directing behaviour was positively related to SWB for both young and older adults. The studies demonstrate that whether meaning making shows benefits for SWB may depend on type of meaning, age and culture. Note that although meaning making was sometimes unrelated to SWB, no detrimental relations to meaning making were found. The discussion focuses on the role of moderators in understanding when meaning making should lead to benefits versus costs to SWB.

Increasing the production of desulfurizing biocatalysts by means of fed - batch culture

2001-01-01

Over the past years, environmental regulations have driven a lot of effort for the development of new technologies for the upgrading of fossil fuels. Biotechnology offers an alternative way to process fossil fuels by means of a biodesulfurization technology where the production of the biocatalyst is one of the key topics. Traditionally, the production is carried out in batch culture where the maximum cellular concentration is restricted by inherent limitations of the culture type and the microorganism growth rate. This work addresses the production of two desulfurizing microorganisms: Rhodococcus erythropolis IGTS8 and gordona rubropertinctus ICP172 using fed-batch culture. Fed-batch cultures were conducted in a 12 L fermentor using ICP 4 medium containing glucose and DMSO as carbon and sulfur sources. As a result, cell concentration was increased 1.5 and 3 times with fed-batch cultures using constant and exponential flow respectively, achieving a maximum cell concentration of 7.3 g DCW/L of biocatalyst igts8 and 12.85 gGDCW/L of the new biocatalyst ICP172. Both biocatalysts presented biodesulfurization activity in a spiked matrix DBT/HXD and in diesel matrix with the detection of 2-HBP which is the end-product of DBT degradation pathway

Experimental and mathematical model of the interactions in the mixed culture of links in the “producer-consumer” cycle

2009-07-01

The paper presents a experimental and mathematical model of interactions between invertebrates (the ciliates Paramecium caudatum and the rotifers Brachionus plicatilis) in the "producer-consumer" aquatic biotic cycle with spatially separated components. The model describes the dynamics of the mixed culture of ciliates and rotifers in the "consumer" component, feeding on the mixed algal culture of the "producer" component. It has been found that metabolites of the algae Scenedesmus produce an adverse effect on the reproduction of the ciliates P. caudatum. Taking into account this effect, the results of investigation of the mathematical model were in qualitative agreement with the experimental results. In the "producer-consumer" biotic cycle it was shown that coexistence is impossible in the mixed culture of invertebrates of the "consumer" component. The ciliates P. caudatum are driven out by the rotifers B. plicatilis.

Finding meaning in first episode psychosis: experience, agency, and the cultural repertoire.

Science.gov (United States)

Larsen, John Aggergaard

2004-12-01

The article examines individuals' attempts to generate meaning following their experiences with psychosis. The inquiry is based on a person-centered ethnographic study of a Danish mental health community program for early intervention in schizophrenia and involves longitudinal interviews with 15 of its participants. The article takes an existential anthropological perspective emphasizing agency and cultural phenomenology to investigate how individuals draw on resources from the cultural repertoire to make sense of personally disturbing experiences during their psychosis. It is suggested that the concept of "system of explanation" has advantages over, for example, "illness narrative" and "explanatory model" when demonstrating how some individuals engage in the creative analytic and theory-building work of bricolage, selecting, adding, and combining various systems of explanation. Delusions are equally derived from the cultural repertoire but are constructed as dogmatic explanations that are idiosyncratic to the individual who holds them.

The use of an in vitro culture system was examined for production of somatic cells suitable for nuclear transfer in the goat. Goat cumulus-oocyte complexes were incubated in tissue culture medium TCM-199 supplemented with 10% fetal bovine serum (FBS) for 20 h. In vitro matured (IVM) oocytes were enucleated and used as karyoplast recipients. Donor cells obtained from the anterior pituitary of an adult male were introduced into the perivitelline space of enucleated IVM oocytes and fused by an electrical pulse. Reconstituted oocytes were cultured in chemically defined medium for 9 days. Two hundred and twenty-eight oocytes (70%) were fused with donor cells. After in vitro culture, seven somatic cell nuclear transfer (SCNT) oocytes (3%) developed to the blastocyst stage. SCNT embryos were transferred to the oviducts of recipient females (four 8-cell embryos per female) or uterine horn (two blastocysts per female). One male clone (NT1) was produced at day 153 from an SCNT blastocyst and died 16 days after birth. This study demonstrates that nuclear transferred goat oocytes produced using an in vitro culture system could develop to term and that donor anterior pituitary cells have the developmental potential to produce term offspring. In this study, it suggested that the artificial control of endocrine system in domestic animal might become possible by the genetic modification to anterior pituitary cells.

Full Text Available The cross-cultural temporary resident population is one of the fastest growing cultural groups in the United States. However, their housing experiences in the new environment have not been extensively studied. Thus, the current study sought to examine meanings of dwelling attributes for cross-cultural temporary residents in the host country. In order to obtain insights into not only functional meanings but also underlying values, a conceptual framework was developed based primarily on Gutman’s (1982 means-end theory and Rapoport’s (1988 three levels of meaning. A case study was conducted using indepth laddering interviews with ten Korean temporary residents in the Lansing, Michigan, area. Seven dwelling attributes emerged from interviews: two satisfactory attributes (i.e., surrounding natural environment and architecture and five unsatisfactory attributes (i.e., carpeted floor, interior lighting, acoustics, bathroom, and entryway. Data were analyzed utilizing the measurement of means-end chain (Gutman, 1982, identifying the lower-level, everyday meanings as well as middle-level, latent meanings of dwelling attributes. A hierarchical value map was used to illustrate the interrelationships among the attributes, consequences, and values. Results revealed that dwelling attributes in participants’ current housing did not effectively satisfy their fundamental needs. In particular, carpeted floor was linked to the greatest number of negative meanings. Moreover, the cultural aspects of Korean housing affected the meanings of dwelling attributes in participants’ current homes. Findings suggest design professionals, facility managers, and policymakers must understand how people from other cultures attach different meanings to the dwelling attributes in their homes and provide more culturally responsive residential environments.

Full Text Available Objective: The aim of this study is the histological and immunohistochemical evaluation of ex vivo produced oral mucosal equivalents using keratinocytes cultured by direct explant technique.Material and Methods: Oral mucosa tissue samples were obtained from the keratinized gingival tissues of 14 healthy human subjects. Human oral mucosa keratinocytes from an oral mucosa biopsy specimen were dissociated by the explant technique. Once a sufficient population of keratinocytes was reached, they were seeded onto the type IV collagen coated “AlloDerm” and taken for histological and immunohistochemical examinations at 11 days postseeding of the keratinocytes on the cadaveric human dermal matrix.Results: Histopathologically and immunohistochemically, 12 out of 14 successful ex vivo produced oral mucosa equivalents (EVPOME that consisted of a stratified epidermis on a dermal matrix have been developed with keratinocytes cultured by the explant technique.Conclusion: The technical handling involved in the direct explant method at the beginning of the process has fewer steps than the enzymatic method and use of the direct explant technique protocol for culturing of human oral mucosa keratinocyte may be more adequate for EVPOME production.

Extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae have been isolated from many regions of the world. Epidemiological studies are being conducted in Europe, North America, and Asia. No study has however been conducted in Africa to determine the prevalence and distribution of ESBLs on the continent. This literature review aimed at describing the prevalence of ESBL-producing Enterobacteriaceae isolated from blood cultures, as well as the ESBL genes involved at the international level. Our focus was mainly on Africa. We conducted a literature review on PubMed. Articles related to our study field and published between 1996 and 2014 were reviewed and entirely read for most of them, while we only focused on the abstracts of some other articles. Relevant articles to our study were then carefully reviewed and included in the review. The prevalence of ESBL-producing Enterobacteriaceae differs from one country to another. The results of our literature review however indicate that class A ESBLs prevail over the other types. We took into consideration articles focusing on various types of samples to assess the prevalence of ESBL-producing Enterobacteriaceae, but information on isolates from blood cultures is limited. The worldwide prevalence of ESBL-producing Enterobacteriaceae has increased over time. Evidence of ESBL-producing Enterobacteriaceae can be found in all regions of the world. Studies conducted in Africa mainly focused on the Northern and Eastern parts of the continent, while only rare studies were carried out in the rest of the continent.

Cardiac disease is the leading cause of death in Lebanon, accounting for 22% to 26% of total deaths in the country. A thorough understanding of perceptions of cardiac illness and related self-care management is critical to the development of secondary prevention programs that are specific to the Lebanese culture. To explore the cultural perceptions of cardiac illness and the associated meaning of self-care among Lebanese patients. Using a qualitative descriptive method, semistructured interviews were conducted with a purposive sample of 15 Lebanese cardiac patients recruited from a medical center in Beirut, Lebanon. The qualitative descriptive analysis yielded one overarching and two other themes describing perceptions of cardiac illness and self-care within the Lebanese cultural context. The overarching cultural theme was, "Lebanese cardiac patients were unfamiliar with the term concept and meaning of self-care." Lebanese cardiac patients thanked God and accepted their fate (Theme I). The participants considered their cardiac incident a life or death warning (Theme II). Health care providers need to consider patients' cultural perception of illness while planning and evaluating cardiac self-care programs. © The Author(s) 2015.

Detection of hydrogen peroxide-producing Lactobacillus species in the vagina: a comparison of culture and quantitative PCR among HIV-1 seropositive women

2012-08-01

Full Text Available Abstract Background The presence of hydrogen peroxide (H2O2 producing Lactobacillus in the vagina may play a role in controlling genital HIV-1 shedding. Sensitive molecular methods improve our ability to characterize the vaginal microbiota; however, they cannot characterize phenotype. We assessed the concordance of H2O2-producing Lactobacillus detected by culture with quantitative PCR (qPCR detection of Lactobacillus species commonly assumed to be H2O2-producers. Methods Samples were collected as part of a prospective cohort study of HIV-1 seropositive US women. Cervicovaginal lavage specimens were tested for L. crispatus and L. jensenii using 16S rRNA gene qPCR assays. Vaginal swabs were cultured for Lactobacillus and tested for H2O2-production. We calculated a kappa statistic to assess concordance between culture and qPCR. Results Culture and qPCR results were available for 376 visits from 57 women. Lactobacilli were detected by culture at 308 (82% visits, of which 233 of 308 (76% produced H2O2. L. crispatus and/or L. jensenii were detected at 215 (57% visits. Concordance between detection of L. crispatus and/or L. jensenii by qPCR and H2O2-producing Lactobacillus by culture was 75% (kappa = 0.45. Conclusions Among HIV-1 seropositive women, there was a moderate level of concordance between H2O2-producing Lactobacillus detected by culture and the presence of L. crispatus and/or L. jensenii by qPCR. However, one-quarter of samples with growth of H2O2-producing lactobacilli did not have L. crispatus or L. jensenii detected by qPCR. This discordance may be due to the presence of other H2O2-producing Lactobacillus species.

2011-03-01

The development of culture processes for hematopoietic progenitors could lead to the development of a complementary source of platelets for therapeutic purposes. However, functional characterization of culture-derived platelets remains limited, which raises some uncertainties about the quality of platelets produced in vitro. The aim of this study was to define the proportion of functional platelets produced in cord blood CD34+ cell cultures. Toward this, the morphological and functional properties of culture-derived platelet-like particles (PLPs) were critically compared to that of blood platelets. Flow cytometry combined with transmission electron microscopy analyses revealed that PLPs formed a more heterogeneous population of platelets at a different stage of maturation than blood platelets. The majority of PLPs harbored the fibrinogen receptor αIIbβ3, but a significant proportion failed to maintain glycoprotein (GP)Ibα surface expression, a component of the vWF receptor essential for platelet functions. Importantly, GPIbα extracellular expression correlated closely with platelet function, as the GPIIb+ GPIbα+ PLP subfraction responded normally to agonist stimulation as evidenced by α-granule release, adhesion, spreading, and aggregation. In contrast, the GPIIb+ GPIbα⁻ subfraction was unresponsive in most functional assays and appeared to be metabolically inactive. The present study confirms that functional platelets can be generated in cord blood CD34+ cell cultures, though these are highly susceptible to ectodomain shedding of receptors associated with loss of function. Optimization of culture conditions to prevent these deleterious effects and to homogenize PLPs is necessary to improve the quality and yields of culture-derived platelets before they can be recognized as a suitable complementary source for therapeutic purposes.

USING THE MEANS OF THEATRE ART TO DEVELOP MODERN TEACHERS’ RHETORICAL CULTURE

Directory of Open Access Journals (Sweden)

2017-04-01

Full Text Available The article examines an important problem of modern education – the use of theatre arts to improve the teachers’ oratorical skills. In the pedagogical context the main categories of theatre pedagogy (co-creation, reincarnation, tempo, rhythm, mise-en-scène, etc. are discussed in details. Thus the congruence of teaching and dramatic art is found out. The essence of artistry is determined as an element of a teacher’s rhetorical culture. The contents, structural elements of Stanislavsky system and their use for developing the teacher’s rhetorical culture are analyzed. The author discusses in details the two main components of Stanislavsky system: an actor’s work itself and the actor’s work on the role. It is proved that both parts of this system with a few adjustments correspond to the method of forming the teacher-speaker’s artistic and rhetorical qualities. The development of teacher’s external techniques includes the preparation of the bodily apparatus for teaching. According to the author’s point of view, a teacher like an actor should have the mental technique to be able to call creative feeling at the right time. Special attention is paid to the various types of artistic training, which is an effective tool for developing the teacher’s rhetorical culture. The system of training includes exercises to develop speech culture, plastic expression, emotional memory, behavior naturalness, etc. The article focuses on the need to study and use the main principles of Stanislavsky system in the teachers’ practical activities. The most effective means of creating a creative mood is physical activity. The author emphasizes the necessity of developing modern-teachers’ artistic and rhetorical qualities by means of theatre pedagogy with the aim of increasing the efficiency of the educational process. The results of the study can be used in the process of training, professional activities and advanced training of education workers.

Palliative care is gaining acceptance across the world. However, even when palliative care resources exist, both the delivery and distribution of services too often are neither equitably nor acceptably provided to diverse population groups. The goal of this study was to illustrate tensions in the delivery of palliative care for diverse patient populations to help clinicians to improve care for all. We begin by defining and differentiating culture, race, and ethnicity, so that these terms-often used interchangeably-are not conflated and are more effectively used in caring for diverse populations. We then present examples from an integrative literature review of recent research on culture and palliative care to illustrate both how and why varied responses to pain and suffering occur in different patterns, focusing on four areas of palliative care: the formation of care preferences, communication patterns, different meanings of suffering, and decision-making processes about care. For each area, we provide international and multiethnic examples of variations that emphasize the need for personalization of care and the avoidance of stereotyping beliefs and practices without considering individual circumstances and life histories. We conclude with recommendations for improving palliative care research and practice with cultural perspectives, emphasizing the need to work in partnerships with patients, their family members, and communities to identify and negotiate culturally meaningful care, promote quality of life, and ensure the highest quality palliative care for all, both domestically and internationally.

Pawar, Sudhanshu S; Vongkumpeang, Thitiwut; Grey, Carl; van Niel, Ed Wj

2015-01-01

Caldicellulosiruptor species have gained a reputation as being among the best microorganisms to produce hydrogen (H2) due to possession of a combination of appropriate features. However, due to their low volumetric H2 productivities (Q H2), Caldicellulosiruptor species cannot be considered for any viable biohydrogen production process yet. In this study, we evaluate biofilm forming potential of pure and co-cultures of Caldicellulosiruptor saccharolyticus and Caldicellulosiruptor owensensis in continuously stirred tank reactors (CSTR) and up-flow anaerobic (UA) reactors. We also evaluate biofilms as a means to retain biomass in the reactor and its influence on Q H2. Moreover, we explore the factors influencing the formation of biofilm. Co-cultures of C. saccharolyticus and C. owensensis form substantially more biofilm than formed by C. owensensis alone. Biofilms improved substrate conversion in both of the reactor systems, but improved the Q H2 only in the UA reactor. When grown in the presence of each other's culture supernatant, both C. saccharolyticus and C. owensensis were positively influenced on their individual growth and H2 production. Unlike the CSTR, UA reactors allowed retention of C. saccharolyticus and C. owensensis when subjected to very high substrate loading rates. In the UA reactor, maximum Q H2 (approximately 20 mmol · L(-1)  · h(-1)) was obtained only with granular sludge as the carrier material. In the CSTR, stirring negatively affected biofilm formation. Whereas, a clear correlation was observed between elevated (>40 μM) intracellular levels of the secondary messenger bis-(3'-5')-cyclic dimeric guanosine monophosphate (c-di-GMP) and biofilm formation. In co-cultures C. saccharolyticus fortified the trade of biofilm formation by C. owensensis, which was mediated by elevated levels of c-di-GMP in C. owensensis. These biofilms were effective in retaining biomass of both species in the reactor and improving Q H2 in a UA reactor using

Meanings of health: interrogating structure and culture.

Dutta, Mohan Jyoti; Basu, Ambar

Based on the argument that context ought to be centralized in discourses of health communication, this article applies the culture-centered approach to engage in dialogue about issues of health with 18 men in rural West Bengal. The culture-centered approach is based on dialogue between the researcher and the community members, with the goals of listening to the voices of cultural members in suggesting culture-based health solutions. In this project, our discursive engagement with the participants suggests that health is primarily constructed as an absence, framed in the realm of minimal access to healthcare resources. In a situation where the resources are limited, the participants discussed the importance of trust in their relationship with the local provider. Health was also seen as a collective resource that was both an asset of the collective and a responsibility of the collective. Finally, the participants also pointed out the ways in which corruption in the structure introduced a paradox in policy discourse and the material conditions of the participants.

Producing health, producing safety. Developing a collective safety culture in radiotherapy

International Nuclear Information System (INIS)

Nascimento, Adelaide

2009-01-01

This research thesis aims at a better understanding of safety management in radiotherapy and at proposing improvements for patient safety through the development of a collective safety culture. A first part presents the current context in France and abroad, addresses the transposition of other safety methods to the medical domain, and discusses the peculiarities of radiotherapy in terms of risks and the existing quality-assurance approaches. The second part presents the theoretical framework by commenting the intellectual evolution with respect to system safety and the emergence of the concept of safety culture, and by presenting the labour collective aspects and their relationship with system safety. The author then comments the variety of safety cultures among the different professions present in radiotherapy, highlights the importance of the collective dimension in correcting discrepancies at the end of the treatment process, and highlights how physicians take their colleagues work into account. Recommendations are made to improve patient safety in radiotherapy

Meanings of Care: A Culture-Centered Approach to Left-Behind Family Members in the Countryside of China.

Sun, Kang; Dutta, Mohan J

2016-11-01

Critical studies of health communication foreground the importance of meanings as organizing frameworks for constituting health. The contested and contradictory meanings articulated around health offer insights into the constraining and enabling roles of structures. Through ethnographic fieldwork conducted in a village in China embedded within the activist framework of the culture-centered approach, this project explores understandings of family care amid left-behind families in rural China against the backdrop of the migration of the middle generation of working adults from families located in rural contexts to cities. We work with the culture-centered approach to explore local meanings of care, understanding everyday care as integral to the health of an aging population that has been erased from the discursive space by market reforms and the hegemonic narrative of national development in China.

Silver nanoparticles were produced by laser ablation of a continuously flowing aerosol of microparticles entrained in argon, nitrogen and helium at a variety of gas pressures. Nanoparticles produced in this new, high-volume nanoparticle production technique are compared with our earlier experiments using laser ablation of static microparticles. Transmission electron micrographs of the samples show the nanoparticles to be spherical and highly non-agglomerated under all conditions tested. These micrographs were analyzed to determine the effect of carrier gas type and pressure on size distributions. We conclude that mean diameters can be controlled from 4 to 20 nm by the choice of gas type and pressure. The smallest nanoparticles were produced in helium, with mean sizes increasing with increasing molecular weight of the carrier gas. These results are discussed in terms of a model based on cooling via collisional interaction of the nanoparticles, produced in the laser exploded microparticle, with the ambient gas

2009-03-01

In this rejoinder to Ann Kindfield and Grady Venville's comments on our article "Reconsidering conceptual change from a socio-cultural perspective: Analyzing students' meaning making in genetics in collaborative learning activities," we elaborate on some of the critical issues they raise. Their comments make apparent some of the crucial differences between a socio-cultural and a socio-cognitive approach towards conceptual change. We have selected some issues that are addressed, either implicitly or explicitly, in their comments. The main issues discussed are talk and interaction as data, the significance of context in interaction studies, the feasibility of generic claims in small-scale interaction studies, and the difference between studying students' understanding of science concepts as opposed to studying the construction of meaning.

Meaning in hoarding: perspectives of people who hoard on clutter, culture and agency.

Science.gov (United States)

Orr, David M R; Preston-Shoot, Michael; Braye, Suzy

2017-12-12

Hoarding has become increasingly prominent in clinical practice and popular culture in recent years, giving rise to extensive research and commentary. Critical responses in the social sciences have criticised the cultural assumptions built in to the construct of 'hoarding disorder' and expressed fears that it may generate stigma outweighing its benefits; however, few of these studies have engaged directly with 'hoarders' themselves. This paper reports on in-depth, semi-structured interviews with 10 individuals living in England, who received assessment and intervention for hoarding from Social Services. Their narratives drew on the cultural repertoire of values and discourses around waste and worth, the mediation of sociality and relationships through material objects, physical constraints on keeping order and the role played by mental health. Analysing these perspectives anthropologically shows how dominant models of hoarding, such as the DSM-5 paradigm, potentially lend themselves to reductionist understandings that efface the meaning 'hoarding' may have and thereby deny agency to the person labelled as 'hoarder'. More culturally informed analysis, by contrast, affords insights into the complex landscape of value, waste, social critique, emotion, interpersonal relationships and practical difficulties that may underlie hoarding cases, and points the way to more person-centred practice and analysis.

Postmortem photography is a widespread practice in perinatal bereavement care, yet few studies have explored how it affects bereaved parents, or how it might be received by parents of older children. This study is an examination of the meaning, utility, and social context of postmortem photography in a sample of 181 bereaved parents. Data were subjected to both quantitative and qualitative analysis. Photographs were positively regarded by most parents after perinatal death and several parents of older children. Other parents rejected postmortem photography for aesthetic, personal, or cultural reasons. Brief recommendations are offered for healthcare providers.

Full Text Available Writing is a skill derived from a long way of learning and exercises. Different from other language skills, writing is considered the difficult language skill to acquire since it involves many aspects of linguistics, social, and writing knowledge and conventions. There are at least three important elements of writing useful to produce a good piece of composition, language competence, writing competence and cultural competence. This paper shows the influence of these three elements in order to produce good, readable, communicative, and successful writing

Rheology of spreadable goat cheese made with autochthonous lactic cultures differing in their ability to produce exopolysaccharides

2013-06-01

Full Text Available The aim of this study was to compare the rheology of spreadable cheeses elaborated with autochthonous lactic starter cultures without the addition of exopolysaccharide-producing strain in the same starter with exopolysaccharide-producing strain. From a rheological standpoint, both samples were characterized as weak viscoelastic gels and pseudoplastic products. It was concluded that cheese made with exopolysaccharide-producing strain showed smaller G', G", and η* values over the range of frequencies studied and smaller critic stress values than the cheese without exopolysaccharide-producing strain. The results obtained indicate that cheeses without exopolysaccharide-producing strain need to be added with any texture enhancer product.

The potential of estuarine microniches as reservoirs of biosurfactant-producing bacteria was evaluated by testing different combinations of inocula and hydrophobic carbon sources. Selective cultures using diesel, petroleum, or paraffin as hydrophobic carbon sources were prepared and inoculated with water from the surface microlayer, bulk sediments, and sediment of the rhizosphere of Halimione portulacoides. These inocula were compared regarding the frequency of biosurfactant-producing strains among selected isolates. The community structure of the selective cultures was profiled using denaturing gradient gel electrophoresis (DGGE) of the 16S rRNA gene fragments at the end of the incubation. The DGGE profiles corresponding to the communities established in selective cultures at the end of the incubation revealed that communities were different in terms of structural diversity. The highest diversity was observed in the selective cultures containing paraffin (H (') = 2.5). Isolates were obtained from the selective cultures (66) and tested for biosurfactant production by the atomized oil assay. Biosurfactant production was detected in 17 isolates identified as Microbacterium, Pseudomonas, Rhodococcus, and Serratia. The combination of estuarine surface microlayer (SML) water as inoculum and diesel as carbon source seems promising for the isolation of surfactant-producing bacteria.

Use of a solid-phase 3H-radioimmunoassay for the measurement of immunoglobulin produced in short-term cultures of antibody-secreting cells

International Nuclear Information System (INIS)

Mongini, P.K.A.; Heber-Katz, E.

1982-01-01

A solid-phase radioimmunoassay (RIA) for assaying immunoglobulin produced from antibody-secreting myeloma, hybridoma and immune spleen cells is described. Specific antibody is detected by culturing antibody-producing cells on antigen-coated flexible polyvinylchloride microtiter wells, washing away the cells, and measuring the bound specific antibody with tritiated affinity-purified anti-isotype reagents. Antibody produced from 10 3 myeloma cells can be detected with as little as 4 h of incubation. With 24-48 h of incubation, antibody from as few as approximately 3-15 myeloma, hybridoma or immune spleen plaque-forming cells (PFC) can be detected. This culture-well RIA has certain distinct advantages over the hemolytic PFC assay and RIA assays in which antibody in culture supernatants is measured. (Auth.)

Polyhydroxyalkanoates (PHA) are biopolymers that can be produced by mixed microbial cultures using wastes or industrial by-products, which represent an economical and environmental advantage over pure culture processes. The use of alternate feedstocks enables using seasonal by-products, providing that the process is resilient to transient conditions. The mixed microbial communities of a 3-stage PHA producing system fed initially with molasses and then cheese whey were investigated through amplicon sequencing of the 16S rRNA gene. The transition in feedstock resulted in an adaptation of the acidogenic community, where Actinobacteria dominated with sugarcane molasses (up to 93% of the operational taxonomic units) and Firmicutes, with cheese whey (up to 97%). The resulting fermentation products profile also changed, with a higher fraction of HV precursors obtained with molasses than cheese whey (7.1±0.5 and 1.7±0.7 gCOD/L, respectively). As for the PHA storing culture, the genera Azoarcus, Thauera and Paracoccus were enriched with fermented molasses (average 89% of Bacteria). Later, fermented cheese whey fostered a higher diversity, including some less characterised PHA-storers such as the genera Paenibacillus and Lysinibacillus. Although the microbial community structure was significantly affected by the feedstock shift, the acidogenic and PHA storing performance of the 3-stage system was very similar once a pseudo steady state was attained, showing that a reliable level of functional redundancy was attained in both mixed cultures.

Full Text Available People all over the world use their hands to communicate expressively. Autonomous gestures, also known as emblems, are highly social in nature, and convey conventionalized meaning without accompanying speech. To study the neural bases of cross-cultural social communication, we used single pulse transcranial magnetic stimulation (TMS to measure corticospinal excitability (CSE during observation of culture-specific emblems. Foreign Nicaraguan and familiar American emblems as well as meaningless control gestures were performed by both a Euro-American and a Nicaraguan actor. Euro-American participants demonstrated higher CSE during observation of the American compared to the Nicaraguan actor. This motor resonance phenomenon may reflect ethnic and cultural ingroup familiarity effects. However, participants also demonstrated a nearly significant (p = 0.053 actor by emblem interaction whereby both Nicaraguan and American emblems performed by the American actor elicited similar CSE, whereas Nicaraguan emblems performed by the Nicaraguan actor yielded higher CSE than American emblems. The latter result cannot be interpreted simply as an effect of ethnic ingroup familiarity. Thus, a likely explanation of these findings is that motor resonance is modulated by interacting biological and cultural factors.

Mixed cultures fermentation can be used to convert organic wastes into various chemicals and fuels. This study examined the fermentation performance of four batch reactors fed with different agricultural (orange, banana, and potato (mechanical and steam)) peel wastes using mixed cultures, and monitored the interval variation of reactor microbial communities with 16S rRNA genes using Illumina sequencing. All four reactors produced similar chemical profile with lactic acid (LA) as dominant compound. Acetic acid and ethanol were also observed with small fractions. The Illumina sequencing results revealed the diversity of microbial community decreased during fermentation and a community of largely lactic acid producing bacteria dominated by species of Lactobacillus developed.

Waltheria americana is a plant used in Mexican traditional medicine to treat some nervous system disorders. The aims of the present study were to isolate and determine the neuropharmacological and neurprotective activities of metabolites produced by a cell suspension culture of Waltheria americana. Submerged cultivation of W. americana cells provided biomass. A methanol-soluble extract (WAsc) was obtained from biomass. WAsc was fractionated yielding the chromatographic fractions 4WAsc-H 2 O and WAsc-CH 2 Cl 2 . For the determination of anticonvulsant activity in vivo, seizures were induced in mice by pentylenetetrazol (PTZ). Neuropharmacological activities (release of gamma amino butyric acid (GABA) and neuroprotection) of chromatographic fractions were determined by in vitro histological analysis of brain sections of mice post mortem. Fraction 4WAsc-H 2 O (containing saccharides) did not produce neuronal damage, neurodegeneration, interstitial tissue edema, astrocytic activation, nor cell death. Pretreatment of animals with 4WAsc-H 2 O and WAsc-CH 2 Cl 2 from W. americana cell suspensions induced an increase in: GABA release, seizure latency, survival time, neuroprotection, and a decrease in the degree of severity of tonic/tonic-clonic convulsions, preventing PTZ-induced death of up to 100% of animals of study. Bioactive compounds produced in suspension cell culture of W. americana produce neuroprotective and neuropharmacological activities associated with the GABAergic neurotransmission system.

Representing and Coping with Early Twentieth-Century Chongqing: “Guide Songs” as Maps, Memory Cells, and Means of Creating Cultural Imagery

Directory of Open Access Journals (Sweden)

Igor Chabrowski

2013-03-01

Full Text Available Chongqing’s “guide songs” form an interesting subgenre among the broad category of haozi 號子 (workers’ songs. These early twentieth-century songs were a form of rhythm-based oral narrative describing Chongqing’s urban spaces, river docks, and harbors. Each toponym mentioned in the lyrics was followed by a depiction of the characteristic associations, whether visible or symbolic, of the place. This article aims to analyze the verbal images of Chongqing presented in these songs in order to understand how the city was remembered, reproduced, and represented. The article deconstructs representations of the city produced by the lower classes, mainly by Sichuan boatmen, and links culturally meaningful images of urban spaces with the historical experiences of work, religion, and historical-mythical memory. It also points to the functions that oral narratives had in the urban environment of early twentieth-century Chongqing. Rhythmic and easy to remember, the songs provided ready-to-use guides and repositories of knowledge useful to anyone living or working there. A cross between utilitarian resource books and cultural representations, they shaped modes of thinking and visualizations of urban spaces and Chongqing. Finally, this article responds to the need to employ popular culture in our thinking about Chinese cities and the multiplicity of meanings they were given in pre-Communist times.

Development and Use of a Real-Time Quantitative PCR Method for Detecting and Quantifying Equol-Producing Bacteria in Human Faecal Samples and Slurry Cultures

Full Text Available This work introduces a novel real-time quantitative PCR (qPCR protocol for detecting and quantifying equol-producing bacteria. To this end, two sets of primers targeting the dihydrodaidzein reductase (ddr and tetrahydrodaidzein reductase (tdr genes, which are involved in the synthesis of equol, were designed. The primers showed high specificity and sensitivity when used to examine DNA from control bacteria, such as Slackia isoflavoniconvertens, Slackia equolifaciens, Asaccharobacter celatus, Adlercreutzia equolifaciens, and Enterorhabdus mucosicola. To demonstrate the validity and reliability of the protocol, it was used to detect and quantify equol-producing bacteria in human faecal samples and their derived slurry cultures. These samples were provided by 18 menopausal women under treatment of menopause symptoms with a soy isoflavone concentrate, among whom three were known to be equol-producers given the prior detection of the molecule in their urine. The tdr gene was detected in the faeces of all these equol-producing women at about 4–5 log10 copies per gram of faeces. In contrast, the ddr gene was only amplified in the faecal samples of two of these three women, suggesting the presence in the non-amplified sample of reductase genes unrelated to those known to be involved in equol formation and used for primer design in this study. When tdr and ddr were present in the same sample, similar copy numbers of the two genes were recorded. However, no significant increase in the copy number of equol-related genes along isoflavone treatment was observed. Surprisingly, positive amplification for both tdr and ddr genes was obtained in faecal samples and derived slurry cultures from two non-equol producing women, suggesting the genes could be non-functional or the daidzein metabolized to other compounds in samples from these two women. This novel qPCR tool provides a technique for monitoring gut microbes that produce equol in humans. Monitoring equol-producing

We evaluate the effects of strontium ranelate on the composition and crystal structure of the biological bone-like apatite produced in osteoblast cell cultures, a system that gave us the advantage of obtaining mineral samples produced exclusively during treatment. Cells were treated with strontium ranelate at concentrations of 0.05 and 0.5 mM Sr(2+). Mineral substances were isolated and analyzed by using a combination of methods: Fourier transform infrared spectroscopy, solid-state (1)H nuclear magnetic resonance, X-ray diffraction, micro-Raman spectroscopy and energy dispersive X-ray spectroscopy. The minerals produced in all cell cultures were typical bone-like apatites. No changes occurred in the local structural order or crystal size of the minerals. However, we noticed several relevant changes in the mineral produced under 0.5 mM Sr(2+): (1) increase in type-B CO3 (2-) substitutions, which often lead to the creation of vacancies in Ca(2+) and OH(-) sites; (2) incorporation of Sr(2+) by substituting slightly less than 10 % of Ca(2+) in the apatite crystal lattice, resulting in an increase in both lattice parameters a and c; (3) change in the PO4 (3-) environments, possibly because of the expansion of the lattice; (4) the Ca/P ratio of this mineral was reduced, but its (Ca+Sr)/P ratio was the same as that of the control, indicating that its overall cation/P ratio was preserved. Thus, strontium ranelate changes the composition and crystal structure of the biological bone-like apatite produced in osteoblast cell cultures.

Hearsay Ethnography: Conversational Journals as a Method for Studying Culture in Action.

Science.gov (United States)

Watkins, Susan Cotts; Swidler, Ann

2009-04-01

Social scientists have long struggled to develop methods adequate to their theoretical understanding of meaning as collective and dynamic. While culture is widely understood as an emergent property of collectivities, the methods we use keep pulling us back towards interview-situated accounts and an image of culture as located in individual experience. Scholars who seek to access supra-individual semiotic structures by studying public rituals and other collectively-produced texts then have difficulty capturing the dynamic processes through which such meanings are created and changed in situ. To try to capture more effectively the way meaning is produced and re-produced in everyday life, we focus here on conversational interactions-the voices and actions that constitute the relational space among actors. Conversational journals provide us with a method: the analysis of texts produced by cultural insiders who keep journals of who-said-what-to-whom in conversations they overhear or events they participate in during the course of their daily lives. We describe the method, distinguishing it from other approaches and noting its drawbacks. We then illustrate the methodological advantages of conversational journals with examples from our texts. We end with a discussion of the method's potential in our setting as well as in other places and times.

Understanding asexual identity as a means to facilitate culturally competent care: A systematic literature review.

2017-12-01

To provide a contemporary overview of asexuality and the implications this has for healthcare practice. Individuals belonging to sexual minority groups face many barriers in accessing appropriate health care. The term "sexual minority group" is usually used to refer to lesbian women, gay, bisexual and transgender individuals. Anecdotal and research evidence suggests that those who identify as asexual have similar poor experiences. Systematic review and qualitative analysis. This work uses a systematic review and qualitative analysis of the existing interview data from self-identified asexuals, to construct features of the asexual identity. The findings will help practitioners and health professionals develop an understanding of this poorly understood construct. Ultimately this work is aimed at facilitating culturally competent care in the context of asexuality. Qualitative analysis produced three themes, which can be used, not only to frame asexuality in a positive and normalising way, but also to provide greater understanding of asexuality, "romantic differences coupled with sexual indifference," "validation through engagement with asexual communities" and "a diversity of subasexual identities." Having some understanding of what it means to identify as asexual, and respecting the choices made by asexuals can markedly improve the experiences of those who embrace an asexual identity when engaging with health care. Anecdotal evidence, taken from one of the largest asexual online forums, suggests that a number of self-identified asexuals choose not to disclose their identity to healthcare professionals through fear of their asexual status being pathologised, problematised or judged. Given that asexuality is a poorly understood concept, this may be due to lack of understanding on behalf of healthcare providers. The review provides health professionals and practitioners working in clinical settings with some insights of the features of an asexual identity to facilitate

2018-01-01

Full Text Available The paper reviews the social situation of development of children and adolescents in the modern society marked by rapid changes. The development of children and adolescents is described as ‘embedding into the culture’ through the education and is closely associated with the formation of their psychological culture. The paper analyses the conditions of personality development in modern children and adolescents, the factors which impede the communication and understanding of other people; it highlights the risks of escaping into the virtual reality or joining asocial groups. The paper also suggests important measures aimed at the formation of psychological culture in children in relation to age-specific tasks of development in primary school and adolescent ages. The development of psychological culture is regarded as the key means of supporting the implementation of modern educational standards as well as the foundation of psychological health in schoolchildren.

Lightfoot, R. C.

Cultures meet and apparently insignificant traits or objects disrupt one of the cultures. This process repeatedly occurred in history with devastating consequences for the affected groups. Personal health, sanity, societies and cultures suffered from the effects of the new intrusions. Insights from sociological theory shed light on the effects and suggest remedies for at least some of the dysfunctions. Strategies for understanding and handling unforeseen changes must be prepared for future contact with other intelligences.

VISUAL CULTURE AS A MEANS OF FORMING A COMMON AND PROFESSIONAL CULTURE OF A PERSON

Directory of Open Access Journals (Sweden)

N. V. Syrova

2018-01-01

Full Text Available Introduction. The article is devoted to the analysis of the visual culture, which forms the general and professional culture of a person in many ways. Attention is paid to the culture of perception of visual images, the ability to analyze them, evaluate, compare, also the features of visual thinking and creative activity, directly relating to it, are considered. The mastering of visual culture is grounded by the specificity of various creative specialties and is a component of the educational process.Materials and Methods. The theory of personality formation and development is the methodological basis of the article. During the research, the analysis of the scientific and theoretical concept of "visual culture" in the system of general and professional human culture was used.Results. The article illustrates that the artistic vision, developed in the process of visual culture formation, starting from childhood, actively participates in the preparation of the ground for the origin of an artistic image, which is realized in the material later. With the development of the creative imagination of the learner, also the development of thinking and memory takes place inevitably, that is harmonization of all parts of the brain is carried out, and this process must be taken into account in the upbringing and education, the formation of the personality, and the formed visual culture is the basis for the improvement of all verges of the student's creative abilities.Discussion and Conclusions. The conclusion is made that visual culture being an integral part of the educational process is the necessary condition for entering the sociocultural space. The education of a high level of visual culture in a modern information and technically replete society is one of the necessary components of the formation of a general and professional culture of a person and it is desirable to begin this process with a student, and even better, from school-days.

2012-09-01

Full Text Available This commentary discusses the anthropological implications of Richard Widess’ paper by summarizing some anthropological approaches to music, especially focusing on the way musical participation inculcates and transmits an aesthetic orientation that guides action across cultural domains such as politics, economics and religion. The paper ends by suggesting that the heart of human culture is more likely to be an aesthetic orientation than a script or set of rules, and traces out some reasons why music does this so well.

Full Text Available The aim of this research is to use isolated and characterized autochthonous functional starter cultures from traditional Croatian dry sausages and to evaluate their capacity for industrial production of five sausages (Čajna sausage, Zimska sausage, Bečka sausage, Srijemska sausage and Slavonski kulen. These defined autochthonous functional starter cultures (combination of Lactobacillus and Staphylococcus strains were used to produce five different industrial sausages which were compared by a panel. The viability of introduced autochthonous Lactobacillus and Staphylococcus strains and their effect on the final product characteristics, namely microbiological, physicochemical and sensory properties were monitored. The obtained results indicate that autochthonous starter cultures survived industrial production of sausages and can be used for production of sausages under controlled conditions. Autochthonous starter cultures obtained better results in the organoleptic evaluation, microbial safety and prolonged shelf-life in comparison with commercial starter cultures.

Influencing agent group behavior by adjusting cultural trait values.

Tuli, Gaurav; Hexmoor, Henry

2010-10-01

Social reasoning and norms among individuals that share cultural traits are largely fashioned by those traits. We have explored predominant sociological and cultural traits. We offer a methodology for parametrically adjusting relevant traits. This exploratory study heralds a capability to deliberately tune cultural group traits in order to produce a desired group behavior. To validate our methodology, we implemented a prototypical-agent-based simulated test bed for demonstrating an exemplar from intelligence, surveillance, and reconnaissance scenario. A group of simulated agents traverses a hostile territory while a user adjusts their cultural group trait settings. Group and individual utilities are dynamically observed against parametric values for the selected traits. Uncertainty avoidance index and individualism are the cultural traits we examined in depth. Upon the user's training of the correspondence between cultural values and system utilities, users deliberately produce the desired system utilities by issuing changes to trait. Specific cultural traits are without meaning outside of their context. Efficacy and timely application of traits in a given context do yield desirable results. This paper heralds a path for the control of large systems via parametric cultural adjustments.

Full Text Available Problems of formation, development and introduction of the modern pedagogical selfdevelopment system in university educational process by means of physical culture and sport have been considered in this article. Such generated pedagogical system reflects practical implementation of social order on the modern educational paradigm aimed at creation of competitive, physically and morally strong individuals. This system promotes selfrealization of students’ individuality in formation of physical culture and sport competencies as well as competencies of selfdevelopment. Contemporary conditions of society’s development and analysis of the world social cultural and educational tendencies show that recently the object of scrupulous society’s attention and the subject of interdisciplinary research have become different aspects of person’s behavior in respect of his health in many highly developed countries. The slogan of such relation is: “Health is not everything but everything without health is nothing”. And this very principle specifies the problems of students’ selfdevelopment during intensive preparation for professional activity in the course of university training. These problems are aimed at maintenance of their health and improvement of physical preparation considering formation of professional motor competences for effective and qualitative mastering of future profession and career after graduation from the university.

BIOCHEMICAL CHARACTERISTICS OF LACTIC ACID PRODUCING BACTERIA AND PREPARATION OF CAMEL MILK CHEESE BY USING STARTER CULTURE

2004-04-01

Full Text Available Lactic acid bacteria (LAB were isolated from camel milk by culturing the milk on specific media and pure culture was obtained by sub-culturing. Purification of culture was confirmed by Gram’s staining and identified by different biochemical tests. Camel milk contained lactic acid producing bacteria like Streptococci such as S. cremoris and S. lactis and Lactobacilli such as L. acidophilus. L. acidophilus grew more rapidly in camel milk than others as its growth was supported by camel milk. Ability of each strain was tested to convert lactose of milk into lactic acid. It was observed that 66% lactose was converted by S. lactis 20, whereas S. cremoris 22 and L. acidophilus 23 converted 56 and 74% lactose into lactic acid, respectively. Effect of freeze-drying was also recorded and the results showed that in all cases there was a slight decrease in the cell count before and after the freeze-drying. The decrease was approximately 0.47, 0.078 and 0.86% for S. lactis 20, S. cremoris 22 and L. acidophilus 23, respectively. Starter culture was prepared from strains isolated from camel milk. Camel and buffalo milk cheese was prepared by using starter culture. The strains isolated from camel milk were best for acid production and coagulated the milk in less time. It is concluded that cheese can be prepared successfully from camel milk and better results can be obtained by coagulating milk with starter culture.

1977-01-01

A scanning radiometer was used to determine the effect of airstream velocity on the mean drop diameter of water sprays produced by pressure atomizing and air atomizing fuel nozzles used in previous combustion studies. Increasing airstream velocity from 23 to 53.4 meters per second reduced the Sauter mean diameter by approximately 50 percent with both types of fuel nozzles. The use of a sonic cup attached to the tip of an air assist nozzle reduced the Sauter mean diameter by approximately 40 percent. Test conditions included airstream velocities of 23 to 53.4 meters per second at 293 K and atmospheric pressure.

The examination of Hevea brasiliensis plants produced by in vitro culture and mutagenesis by DNA fingerprinting techniques

Low, F.C.; Atan, S.; Jaafar, H.

1998-01-01

Rubber (Hevea brasiliensis) plants derived from anther and ovule culture as well as gamma-irradiated plants were examined by several DNA marker techniques. These include restriction fragment length polymorphisms (RFLPs), random amplified polymorphic DNA (RAPD), sequence tagged microsatellite sites (STMS), DNA amplification fingerprinting (DAF) and amplified fragment length polymorphisms (AFLPs). Compared to control plants produced by vegetative propagation (cutting and budding), plants produced by in vitro culture appeared to have a reduction in the number of rDNA loci. Two RAPD protocols were compared and found to be similar in amplification of the major DNA bands. After confirmation that the RAPD method adopted was reproducible, the technique was applied to the present studies. Eight out of the 60 primers screened were able to elicit polymorphisms between pooled DNA from in vitro culture plants. Variations in DNA patterns were observed between pooled DNA samples of anther-derived plants as well as between anther-derived and ovule-derived plants. Comparisons of RAPD patterns obtained between anther-derived plants exposed to increasing dosages of gamma-irradiation with non irradiated anther-derived plants revealed distinct DNA polymorphisms. The changes in DNA profiles did not appear to be correlated to the dosage of irradiation. Since somaclonal variation was detected, it was difficult to identify changes which were specifically caused by irradiation. Application of the STMS technique to tag micro satellite sequences (GA) n , (TA) n and (TTA) n in the hydroxymethylglutaryl coenzyme A reductase-1 (hmgr-1) gene failed to detect differences between plants derived from anther and ovule culture. Although restriction endonuclease digestions with methylation sensitive enzymes suggested that four in vitro culture plants examined exhibited similar digestion patterns as the controls, a change in cytosine methylation in one anther-derived plant was detected.

Full Text Available Starch is a plant polysaccharide with unique applications in Iran. Its increasing production and processing recently have led to large volumes of industrial effluent as an environmental pollutant. In this study, an amylase producing yeast is isolated and identified as “Cryptococcus aerius” to investigate some of its characteristics such as its amylase secretion and starch digesting patterns, kinetics of amylase complex, and its capability for carotenoid production in dual culture. The results indicate that C.aerius is capable of soluble and raw maize starch digestion and assimilation. Raw starch digestion is scarce among yeast species; hence, it is industrially important. C.aerius digests soluble starch in the first 10 hours of cultivation and on the basis of amylase secreting patterns, it is therefore categorized with fast growing species on starch as carbon source. Non-pathogenicity, digestion of raw starch, heat stability of the secreted amylases complex (>55˚C, and the optimum pH level of 5.5- 6 for amylases complex are the set of properties that make this species capable of use in microbial production on an industrial scale. Absorption of carotenoid extract obtained from dual fermentation of C.aerius and Rhodotorula sp. indicates that the quality of carotenoids produced in dual fermentation is the same as that produced from pure Rhodotorula sp culture.

Cultural based preconceptions in aesthetic experience of architecture

2011-01-01

Full Text Available On a broader scale, the aim of this paper is to examine theoretically the effects a cultural context has on the aesthetic experience of images existing in perceived reality. Minimalism in architecture, as direct subject of research, is a field of particularities in which we observe functioning of this correlation. Through the experiment with the similarity phenomenon, the paper follows specific manifestations of general formal principles and variability of meaning of minimalism in architecture in limited areas of cultural backgrounds of Serbia and Japan. The goal of the comparative analysis of the examples presented is to indicate the conditions that may lead to a possibly different aesthetic experience in two different cultural contexts. Attribution of different meanings to similar formal visual language of architecture raises questions concerning the system of values, which produces these meanings in their cultural and historical perspectives. The establishment of values can also be affected by preconceptions resulting from association of perceived similarities. Are the preconceptions in aesthetic reception of architecture conditionally affected by pragmatic needs, symbolic archetypes, cultural metaphors based on tradition or ideologically constructed dogmas? Confronting philosophical postulates of the Western and Eastern traditions with the transculturality theory of Wolfgang Welsch, the answers may become more available.

Kuwae, Shinobu; Miyakawa, Ichiko; Doi, Tomohiro

2018-01-11

A chemically defined platform basal medium and feed media were developed using a single Chinese hamster ovary (CHO) cell line that produces a monoclonal antibody (mAb). Cell line A, which showed a peak viable cell density of 5.9 × 10 6  cells/mL and a final mAb titer of 0.5 g/L in batch culture, was selected for the platform media development. Stoichiometrically balanced feed media were developed using glucose as an indicator of cell metabolism to determine the feed rates of all other nutrients. A fed-batch culture of cell line A using the platform fed-batch medium yielded a 6.4 g/L mAb titer, which was 12-fold higher than that of the batch culture. To examine the applicability of the platform basal medium and feed media, three other cell lines (A16, B, and C) that produce mAbs were cultured using the platform fed-batch medium, and they yielded mAb titers of 8.4, 3.3, and 6.2 g/L, respectively. The peak viable cell densities of the three cell lines ranged from 1.3 × 10 7 to 1.8 × 10 7  cells/mL. These results show that the nutritionally balanced fed-batch medium and feeds worked well for other cell lines. During the medium development, we found that choline limitation caused a lower cell viability, a lower mAb titer, a higher mAb aggregate content, and a higher mannose-5 content. The optimal choline chloride to glucose ratio for the CHO cell fed-batch culture was determined. Our platform basal medium and feed media will shorten the medium-development time for mAb-producing cell lines.

In this study, the effects of two different commercial starter culture mixes and processing methodologies (traditional and heat process) on the lipolytic changes of fermented sausages manufactured with turkey meat were evaluated during processing stages and storage. Free fatty acid (FFA) value increased with fermentation and during storage over 120 d in all fermented sausage groups produced with both processing methodologies (p<0.05). After drying stage, free fatty acid values of traditional style and heat processed fermented sausages were between 10.54-13.01% and 6.56-8.49%, respectively. Thiobarbituric acid (TBA) values of traditionally processed fermented sausages were between 0.220-0.450 mg·kg(-1), and TBA values of heat processed fermented sausages were in a range of 0.405-0.795 mg·kg(-1). Oleic and linoleic acids were predominant fatty acids in all fermented sausages. It was seen that fermented sausage groups produced with starter culture had lower TBA and FFA values in comparison with the control groups, and heat application inhibited the lipase enzyme activity and had an improving effect on lipid oxidation. As a result of these effects, heat processed fermented sausages had lower FFA and higher TBA values than the traditionally processed groups.

Variation in radiation use efficiency (RUE) amongst 81 rice cultures was assessed at Hyderabad, Maruteru and Pattambi locations. The RUE was computed for each culture at panicle initiation stage (RUE p i) and at physiological maturity (RUE m ) for each location. RUE p i and RUE m differed significantly amongst cultures and also between locations. The interaction between location and cultures was also found to be highly significant. The mean RUE p i for all the cultures was 1.08, 0.56 and 1.22 g MJ -1 , respectively, for HYD, MTU and PTB. The average RUE m estimated was 0.37, 0.60 and 0.93, respectively, for HYD, MTU and PTB. Out of the 81 rice cultures, very few entries consistently showed high RUE at all the three locations and at both the stages. The cultures lET 21023 and lET 20986 recorded higher, though not the highest, RUE, at panicle initiation and maturity stages at all the three locations and produced TDM and grain yield higher than the mean TDM and grain yield for all the test cultures.

Full Text Available This paper investigates the exchange and circulation of ideas in the black diaspora, particularly in the newspaper The Example, mapping and discussing the ethnic-racial and gender representations constructed in the narratives produced by the editors of this newspaper, during the campaign for the construction of a monument to the “Black Mother”. The aim is to analyze how the newspaper’s editors have appropriated texts that circulated in other newspapers about the campaign to the monument of the “Black Mother”, adapted them to their own interests and given them new meanings. From the theoretical approach of Cultural Studies, we understand the black press as a cultural artifact that not only informs but also produces discourses and representations that contribute to the formation of black subjectivities and identities.

Previous studies have shown that we need to distinguish between means and end information about actions. It is unclear how these two subtypes of action information relate to each other with theoretical accounts postulating the superiority of end over means information and others linking separate means and end routes of processing to actions of differential meaningfulness. Action meaningfulness or familiarity differs between cultures. In a cross-cultural setting, we investigated how action familiarity influences recognition memory for means and end information. Object directed actions of differential familiarity were presented to Chinese and German participants. Action familiarity modulated the representation of means and end information in both cultures in the same way, although the effects were based on different stimulus sets. Our results suggest that, in the representation of actions in memory, end information is superordinate to means information. This effect is independent of culture whereas action familiarity is not.

During certain wine fermentation processes, yeasts, and mainly non-Saccharomyces strains, produce and secrete enzymes such as β-glucosidases, proteases, pectinases, xylanases and amylases. The effects of enzyme activity on the aromatic quality of wines during grape juice fermentation, using different co-inoculation strategies of non-Saccharomyces and Saccharomyces cerevisiae yeasts, were assessed in the current study. Three strains with appropriate enological performance and high enzymatic activities, BSc562 (S. cerevisiae), BDv566 (Debaryomyces vanrijiae) and BCs403 (Candida sake), were assayed in pure and mixed Saccharomyces/non-Saccharomyces cultures. β-Glucosidase, pectinase, protease, xylanase and amylase activities were quantified during fermentations. The aromatic profile of pure and mixed cultures was determined at the end of each fermentation. In mixed cultures, non-Saccharomyces species were detected until day 4-5 of the fermentation process, and highest populations were observed in MSD2 (10% S. cerevisiae/90% D. vanrijiae) and MSC1 (1% S. cerevisiae/99% C. sake). According to correlation and multivariate analysis, MSD2 presented the highest concentrations of terpenes and higher alcohols which were associated with pectinase, amylase and xylanase activities. On the other hand, MSC1 high levels of β-glucosidase, proteolytic and xylanolytic activities were correlated to esters and fatty acids. Our study contributes to a better understanding of the effect of enzymatic activities by yeasts on compound transformations that occur during wine fermentation.

Culture-centered engagement with delivery of health services: co-constructing meanings of health in the Tzu Chi Foundation through Buddhist philosophy.

Dillard, Sydney J; Dutta, Mohan; Sun, Wei-San

2014-01-01

The shift in health communication scholarship from the narrow focus on curing to the complexly intertwined spaces of health, illness, healing, and curing attends to the dynamic cultural contexts within which meanings and practices are negotiated, directing scholarship toward alternative spaces of health care delivery. This study utilized the culture-centered approach as a theoretical lens for providing a discursive space for understanding meanings of health constituted in the practices of the Tzu Chi Foundation, an organization that offers biomedical services within the larger philosophical understandings of Buddhism with 10 million members in over 50 different countries. The emerging perspective promotes non-biomedical meanings of health through selfless giving and assistance founded in Buddhist principles, simultaneously seeking purity of the mind, body, and soul holistically. Through the negotiation of the principles driving Buddhist philosophy and the principles that shape biomedical health care delivery, this study seeks to understand the interpretive frames that circulate among foundation staff and care recipients.

A Rapid Culture Technique Produces Functional Dendritic-Like Cells from Human Acute Myeloid Leukemia Cell Lines

Full Text Available Most anti-cancer immunotherapeutic strategies involving dendritic cells (DC as vaccines rely upon the adoptive transfer of DC loaded with exogenous tumour-peptides. This study utilized human acute myeloid leukemia (AML cells as progenitors from which functional dendritic-like antigen presenting cells (DLC were generated, that constitutively express tumour antigens for recognition by CD8+ T cells. DLC were generated from AML cell lines KG-1 and MUTZ-3 using rapid culture techniques and appropriate cytokines. DLC were evaluated for their cell-surface phenotype, antigen uptake and ability to stimulate allogeneic responder cell proliferation, and production of IFN-γ; compared with DC derived from normal human PBMC donors. KG-1 and MUTZ-3 DLC increased expression of CD80, CD83, CD86, and HLA-DR, and MUTZ-3 DLC downregulated CD14 and expressed CD1a. Importantly, both KG-1 and MUTZ-3-derived DLC promoted proliferation of allogeneic responder cells more efficiently than unmodified cells; neither cells incorporated FITC-labeled dextran, but both stimulated IFN-γ production from responding allogeneic CD8+ T cells. Control DC produced from PBMC using the FastDC culture also expressed high levels of critical cell surface ligands and demonstrated good APC function. This paper indicates that functional DLC can be cultured from the AML cell lines KG-1 and MUTZ-3, and FastDC culture generates functional KG-1 DLC.

Cultural ergonomics is an approach that considers interaction- and experience-based variations among cultures. Designers need to develop a better understanding of cultural ergonomics not just to participate in cultural contexts but also to develop interactive experiences for users. Cultural ergonomics extends our understanding of cultural meaning and our ability to utilize such understanding for design and evaluate everyday products. This study aims to combine cultural ergonomics and interactive design to explore human-culture interaction in user experiences. The linnak is a typical Taiwanese aboriginal cultural object. This study examined the cultural meaning and operational interface of the linnak, as well as the scenarios in which it is used in interaction and user experiences. The results produced a cultural ergonomics interface for examining the manner in which designers communicate across cultures as well as the interweaving of design and culture in the design process.

Phototrophic hydrogen production from glucose by pure and co-cultures of Clostridium butyricum and Rhodobacter sphaeroides was studied in batch experiments. Results showed that in all batches hydrogen was produced after a lag phase of about 10h; pure culture of R. sphaeroides produced hydrogen at rates substantially lower than C. butyricum. In co-culture systems, R. sphaeroides even with cell populations 5.9 times higher still could not compete with C. butyricum for glucose. In co-culture systems, R. sphaeroides syntrophically interacted with C. butyricum, using the acetate and butyrate produced by the latter as substrate for hydrogen production. Hydrogen production was ceased in all batches when the pH was lowered to the level of pH 6.5, resulting from the accumulation of fatty acids. It was also demonstrated in this study that fluorescence in situ hybridization (FISH) was an effective means for the quantification of the relative abundance of individual bacteria in a co-culture system.

The scorpion Buthus martensii Karsch has been used in Traditional Chinese Medicine to treat neuronal diseases such as neuropathic pain, paralysis and epilepsy for thousands of years. Studies have demonstrated that scorpion venom is the primary active component. Although scorpion venom can effectively attenuate pain in the clinic, it also produces neurotoxic response. In this study, toxicity guided purification led to identify a mammalian toxin termed BmK NT1 comprising of 65 amino acid residues and an amidated C-terminus, a mature peptide encoded by the nucleotide sequence (GenBank No. AF464898). In contract to the recombinant product of the same nucleotide sequence, BmK AGAP, which displayed analgesic and anti-tumor effect, intravenous injection (i.v.) of BmK NT1 produced acute toxicity in mice with an LD50 value of 1.36 mg/kg. In primary cultured cerebellar granule cells, BmK NT1 produced a concentration-dependent cell death with an IC50 value of 0.65 μM (0.41-1.03 μM, 95% Confidence Intervals, 95% CI) which was abolished by TTX, a voltage-gated sodium channel (VGSC) blocker. We also demonstrated that BmK NT1 produced modest sodium influx in cerebellar granule cell cultures with an EC50 value of 2.19 μM (0.76-6.40 μM, 95% CI), an effect similar to VGSC agonist, veratridine. The sodium influx response was abolished by TTX suggesting that BmK NT1-induced sodium influx is solely through activation of VGSC. Considered these data together, we demonstrated that BmK NT1 activated VGSC and produced neurotoxicity in cerebellar granule cell cultures. Copyright © 2015 Elsevier Ltd. All rights reserved.

Dietary low-digestible carbohydrates (LDCs) affect gut microbial metabolism, including the production of short-chain fatty acids. The ability of various LDCs to promote butyrate production was evaluated in in vitro human fecal cultures. Fecal suspensions from five healthy males were anaerobically incubated with various LDCs. L-Sorbose and xylitol markedly promoted butyrate formation in cultures. Bacterial 16S rRNA gene-based denaturing gradient gel electrophoresis analyses of these fecal cultures revealed a marked increase in the abundance of bacteria closely related to the species Anaerostipes hadrus or A. caccae or both, during enhanced butyrate formation from L-sorbose or xylitol. By using an agar plate culture, two strains of A. hadrus that produced butyrate from each substrate were isolated from the feces of two donors. Furthermore, of 12 species of representative colonic butyrate producers, only A. hadrus and A. caccae demonstrated augmented butyrate production from L-sorbose or xylitol. These findings suggest that L-sorbose and xylitol cause prebiotic stimulation of the growth and metabolic activity of Anaerostipes spp. in the human colon. © FEMS 2016. All rights reserved.

2014-05-01

Full Text Available Global society requires acceleration and diversification of ways data’s transmission, erasing the boundaries between people and nations. However, there always will be a certain sign that distinguishes one ethnic group among others. Ethno­cultural specificity is kept and transmitted by various means. Cuisine as one of the most important everyday realities is also transmitting ethnic and cultural meanings. Moreover, each dish is a kind of special semiotic text content. Are there reasons that motivate each of us to choose the dishes? Do our choices genetically depend on our ancestors? Or just have a set of personal culinary preferences? The national dish is one of the cultural and historical features. Every national cuisine established concepts that have appeared in the process of communication. Borsch is such a concept and the ethnic mark for Ukrainians at the same time. Cooking and eating is a synthetic type of communication that produces transmission and perception of information kinesthetic, auditory and visual methods. Except the usual everyday dishes there are festive that are becoming solemn, not average.

The model alga Chlamydomonas reinhardtii requires acetate as a co-substrate for optimal production of lipids, and the addition of acetate to culture media has practical and economic implications for algal biofuel production. Here we demonstrate the growth of C. reinhardtii on acetate provided by mutant strains of the cyanobacterium Synechococcus sp. PCC 7002. Optimal growth conditions for co-cultivation of C. reinhardtii with wild-type and mutant strains of Synechococcus sp. 7002 were established. In co-culture, acetate produced by a glycogen synthase knockout mutant of Synechococcus sp. PCC 7002 was able to support the growth of a lipid-accumulating mutant strain of C. reinhardtii defective in starch production. Encapsulation of Synechococcus sp. PCC 7002 using an alginate matrix was successfully employed in co-cultures to limit growth and maintain the stability. The ability of immobilized strains of the cyanobacterium Synechococcus sp. PCC 7002 to produce acetate at a level adequate to support the growth of lipid-accumulating strains of C. reinhartdii offers a potentially practical, photosynthetic alternative to providing exogenous acetate into growth media.

Full Text Available Processing of alpine milk in malga farms is carried out under conditions that can favor contamination by coliforms, coagulase-positive staphylococci, or pathogens such as Listeria monocytogenes. With the aim to improve the hygienic characteristics and safety of cheese produced in four malga farms the use of lyophilized Natural Milk Culture prepared with selected strains was tested. Two cheesemaking tests were carried out in the same day always starting from the same milk: in the first case following the malga recipe that uses either Natural Whey Culture or without the addition of a starter, in the second one using a Natural Milk Culture. Cheesemaking were carried out in four malga farms located in the west area of Trentino region within the same week. For hygienic and safety evaluation, aerobic colony count, coagulase-positive staphylococci, Escherichia coli, staphylococcal toxins, Listeria monocytogenes , and Salmonella spp, pH and aw were determined in raw milk from evening and morning milking, curd in vat, curd after extraction and two months-ripened cheese. Pathogens or toxins, high values of coagulase- positive staphylococci and E. coli were not found in cheese samples. However, in the curd coagulase-positive staphylococci reached values almost of 5 Log CFU/g in the two malga without starter cultures. The use of Natural Milk Culture reduced E. coli counts. In addition, DNA was extracted from cheese samples and from Natural Milk Culture and the composition of the microbial community determined by Next Generation Sequencing method. The determination of cheese microbial communities demonstrated that the use of Natural Milk Culture exerted different effects in the different malga, in any case preserving bacterial biodiversity.

Wordplay in Advertising: Form, Meaning and Function

Directory of Open Access Journals (Sweden)

Sara Laviosa

2015-10-01

Full Text Available Generally speaking, wordplay (or pun is a witticism that relies for its effect on playing with different levels of language, i.e. phonological, graphological, morphological, lexical, syntactic, and textual. Puns are frequently used in commercial advertising as a rhetorical device to promote a given product or service by creating humour, attracting the reader’s attention and adding persuasive force to the message. They also reflect the cultural preferences and traditions of a country, therefore they can be fruitfully used for pedagogic purposes to raise awareness of the specific linguistic and cultural features of the foreign language. In this paper  I examine the form, meaning and function of puns that rely on the different meanings of polysemic words, the literal and non-literal senses of idioms or on bringing two homonyms together in the same utterance to produce witty remarks. After introducing the notions of homonymy, polysemy and idiom I analyse the play on words contained in a sample of advertisements selected at random from two broadsheet newspapers, The Guardian Weekend (1997 and The Independent (1997, two quality weekly magazines, Cosmopolitan (1997 and The Telegraph Magazine (1997, as well as a promotional brochure by Alliance & Leicester plc (2003 and promotional leaflets published in 2000 respectively by Royal Mail, British Telecommunications plc and Johnson & Johnson. Finally, I propose some activities that can be carried out in the LSP classroom either individually or in groups to raise awareness of some of the linguistic and cultural features characterizing the rhetoric of marketing and promotion in business language.

Hung, L L; Sylvia, D M

1988-02-01

Bahia grass (Paspalum notatum) and industrial sweet potato (Ipomoea batatas) colonized by Glomus deserticola, G. etunicatum, and G. intraradices were grown in aeroponic cultures. After 12 to 14 weeks, all roots were colonized by the inoculated vesicular-arbuscular mycorrhizal fungi. Abundant vesicles and arbuscules formed in the roots, and profuse sporulation was detected intra-and extraradically. Within each fungal species, industrial sweet potato contained significantly more roots and spores per plant than bahia grass did, although the percent root colonization was similar for both hosts. Mean percent root colonization and sporulation per centimeter of colonized root generally increased with time, although with some treatments colonization declined by week 14. Spore production ranged from 4 spores per cm of colonized root for G. etunicatum to 51 spores per cm for G. intraradices. Infectivity trials with root inocula resulted in a mean of 38, 45, and 28% of bahia grass roots colonized by G. deserticola, G. etunicatum, and G. intraradices, respectively. The germination rate of G. etunicatum spores produced in soil was significantly higher than that produced in aeroponic cultures (64% versus 46%) after a 2-week incubation at 28 degrees C. However, infectivity studies comparing G. etunicatum spores from soil and aeroponic culture indicated no biological differences between the spore sources. Aeroponically produced G. deserticola and G. etunicatum inocula retained their infectivity after cold storage (4 degrees C) in either sterile water or moist vermiculite for at least 4 and 9 months, respectively.

Both of culture temperature and pH value had impacts on the degree of uranium extraction through changing types and concentrations of mixed organic acids produced by Aspergillus niger, and significant interactions existed between them though pH value played a leading role. And with the change of pH value of mixed organic acids, the types and contents of mixed organic acids changed and impacted on the degree of uranium extraction, especially oxalic acid, citric acid and malic acid. The mean degree of uranium extraction rose to peak when the culture temperature was 25 deg C (76.14 %) and pH value of mixed organic acids was 2.3 (82.40 %) respectively. And the highest one was 83.09 %. The optimal culture temperature (25 deg C) of A. niger for uranium leaching was different from the most appropriate growing temperature (37 deg C). (author)

Evolution of a recombinant (gucoamylase-producing) strain of Fusarium venenatum A3/5 in chemostat culture.

Wiebe, M G; Robson, G D; Shuster, J; Trinci, A P

2001-04-20

Fusarium venenatum JeRS 325 is a transformant of strain A3/5 which produces Aspergillus niger glucoamylase (GAM) under the control of a Fusarium oxysporum trypsin-like protease promoter. The evolution of JeRS 325 was studied in glucose-limited chemostat cultures grown on NaNO3 or (NH4)2SO4 as the nitrogen source. Thirteen mutants which were more highly branched and four mutants which were more sparsely branched than the parental strain were isolated from the NaNO3 chemostat. The highly branched mutants detected in this chemostat did not displace the sparsely branched population. The mutants isolated from the NaNO3 chemostat complemented representative strains previously isolated from glucose-limited chemostat cultures of F. venenatum A3/5 grown on (NH4)2SO4, but showed little complementation between themselves. By contrast, a highly branched mutant isolated from the (NH4)2SO4 chemostat culture displaced the sparsely branched mycelial population. None of the mutants isolated from the NaNO3 or (NH4)2SO4 chemostats produced as much GAM as JeRS 325. Southern blot analysis showed that all except one mutant had lost copies of both the glucoamylase and the acetamidase (the selectable marker) genes. However, specific GAM production was not necessarily correlated with the extent of glaA gene loss observed. Further, 10 of the mutants had lost the ability to grow on acetamide as the sole nitrogen source, although they retained copies of the amdS gene. In competition studies, mutants which could not utilize acetamide displaced mutants which could. The presence of foreign DNA in JeRS 325 resulted in a reduced specific growth rate (compared to A3/5), but the presence of the foreign DNA did not prevent the evolution of the strain or the isolation of mutants which had improved growth rates.

Isotopically labeled tomato carotenoids, phytoene, phytofluene, and lycopene, are needed for mammalian bioavailability and metabolism research but are currently commercially unavailable. The goals of this work were to establish and screen multiple in vitro tomato cell lines for carotenoid production, test the best producers with or without the bleaching herbicides, norflurazon and 2-(4-chlorophenyl-thio)triethylamine (CPTA), and to use the greatest carotenoid accumulator for in vitro 13C-labeling. Different Solanum lycopersicum allelic variants for high lycopene and varying herbicide treatments were compared for carotenoid accumulation in callus and suspension culture, and cell suspension cultures of the hp-1 line were chosen for isotopic labeling. When grown with [U]-13C-glucose and treated with CPTA, hp-1 suspensions yielded highly enriched 13C-lycopene with 45% of lycopene in the M+40 form and 88% in the M+35 to M+40 isotopomer range. To the authors' knowledge this is the first report of highly enriched 13C-carotenoid production from in vitro plant cell culture.

Unusual Δ7,12,19 C35:3 Alkenone Produced by the Mutant Emiliania huxleyi strain CCMP2758 in Culture

Alkenones with chain length ranging from C37 to C40 are highly specific biomarkers for certain haptophyte algae in ocean and lake sediments and have been widely used for paleoclimate studies. Short chain alkenones (e.g., C35 and C36) have been found in environmental and culture samples but the origin and structures of these compounds are not fully understood. The benchmark marine alkenone producer, Emiliania huxleyi CCMP2758 strain (the mutant of strain CCMP1742, NEPCC55a) was reported to make 35:2 alkenone when cultured at 15 °C (Prahl et al., 2006). Here we show, when this strain is cultured at lower temperatures (e.g., 4°C), CCMP2758 produces large amount of 35:3 alkenone with unusual double bond positions of Δ7,12,19. We determined the double bond positions of the C35:3 methyl ketonee based on GC-MS analysis of cyclobutylimine derivatives and dimethyl disulfide derivatives respectively, and provide the first temperature calibrations based on the unsaturation ratios of C35 alkenones. Previous studies have found 35:2 alkenone with three methylene interruption in the Black Sea sediment, but it is the first time that an alkenone with a mixed three and five methylene interruption is found. The discovery of short chain alkenones with unusual double bond positions may shed new light to alkenone biosynthesis.

Mean flow produced by small-amplitude vibrations of a liquid bridge with its free surface covered with an insoluble surfactant

Science.gov (United States)

Carrión, Luis M.; Herrada, Miguel A.; Montanero, José M.; Vega, José M.

2017-09-01

As is well known, confined fluid systems subject to forced vibrations produce mean flows, called in this context streaming flows. These mean flows promote an overall mass transport in the fluid that has consequences in the transport of passive scalars and surfactants, when these are present in a fluid interface. Such transport causes surfactant concentration inhomogeneities that are to be counterbalanced by Marangoni elasticity. Therefore, the interaction of streaming flows and Marangoni convection is expected to produce new flow structures that are different from those resulting when only one of these effects is present. The present paper focuses on this interaction using the liquid bridge geometry as a paradigmatic system for the analysis. Such analysis is based on an appropriate post-processing of the results obtained via direct numerical simulation of the system for moderately small viscosity, a condition consistent with typical experiments of vibrated millimetric liquid bridges. It is seen that the flow patterns show a nonmonotone behavior as the Marangoni number is increased. In addition, the strength of the mean flow at the free surface exhibits two well-defined regimes as the forcing amplitude increases. These regimes show fairly universal power-law behaviors.

The effect of cultural interaction on cumulative cultural evolution.

Science.gov (United States)

Nakahashi, Wataru

2014-07-07

Cultural transmission and cultural evolution are important for animals, especially for humans. I developed a new analytical model of cultural evolution, in which each newborn learns cultural traits from multiple individuals (exemplars) in parental generation, individually explores around learned cultural traits, judges the utility of known cultural traits, and adopts a mature cultural trait. Cultural evolutionary speed increases when individuals explore a wider range of cultural traits, accurately judge the skill level of cultural traits (strong direct bias), do not strongly conform to the population mean, increase the exploration range according to the variety of socially learned cultural traits (condition dependent exploration), and make smaller errors in social learning. Number of exemplars, population size, similarity of cultural traits between exemplars, and one-to-many transmission have little effect on cultural evolutionary speed. I also investigated how cultural interaction between two populations with different mean skill levels affects their cultural evolution. A population sometimes increases in skill level more if it encounters a less skilled population than if it does not encounter anyone. A less skilled population sometimes exceeds a more skilled population in skill level by cultural interaction between both populations. The appropriateness of this analytical method is confirmed by individual-based simulations. Copyright © 2014 Elsevier Ltd. All rights reserved.

Do I mean what I say and say what I mean? A cross cultural ap-proach to the use of emoticons & emojis in CMC messages

Full Text Available The use of emoticons and emojis among online messaging users has achieved a globalized level. This article aims at examining how certain emojis and emoticons are chosen by message senders to regular the intensity of emotions in their messages. Or, by means of using them, message senders wish to blur textual rigidity and show interaction empathy during the communication process. This study analyzes the use of these symbols and graphic elements in message exchange through CMC and SNS, where users from different culture background convey their feeling. For it, two empirical studies of a methodological design were carried out: One pilot study was intended for the research instrument validation. The second was a survey study. By testing online messaging habit, this study enabled the researchers to observe whether the senders inclined to linguistic text use only, or they preferred including an additional emoticon or emoji in their message to communicate their feelings. Results of this research show that, at a certain extent, massage senders’ different culture background could influence on their emotional expressivity level.

Culture evolves according to dynamics on multiple temporal scales, from individuals' minute-by-minute behaviour to millennia of cultural accumulation that give rise to population-level differences. These dynamics act on a range of entities-including behavioural sequences, ideas and artefacts as well as individuals, populations and whole species-and involve mechanisms at multiple levels, from neurons in brains to inter-population interactions. Studying such complex phenomena requires an integration of perspectives from a diverse array of fields, as well as bridging gaps between traditionally disparate areas of study. In this article, which also serves as an introduction to the current special issue, we highlight some specific respects in which the study of cultural evolution has benefited and should continue to benefit from an integrative approach. We showcase a number of pioneering studies of cultural evolution that bring together numerous disciplines. These studies illustrate the value of perspectives from different fields for understanding cultural evolution, such as cognitive science and neuroanatomy, behavioural ecology, population dynamics, and evolutionary genetics. They also underscore the importance of understanding cultural processes when interpreting research about human genetics, neuroscience, behaviour and evolution.This article is part of the theme issue 'Bridging cultural gaps: interdisciplinary studies in human cultural evolution'. © 2018 The Author(s).

The frequency of cyanobacterial blooms has been increasing all over the world. These blooms are often toxic and have become a serious health problem. The aim of this work was to search for population density control mechanisms that could inhibit the proliferation of the toxic bloom-forming genus Microcystis. Microcystis PCC 7806 cultured for long periods in liquid ASM-1 medium loses its characteristic green colour. When a medium of chlorotic cultures is added to a nutrient-replete culture, cell density increase is drastically reduced when compared with controls. Inhibition of cell proliferation occurs in Microcystis cultures from any growth stage and was not strain-specific, but other genera tested showed no response. Investigations on the mechanism of growth inhibition showed that cultures treated with the conditioned medium acquired a pale colour, with pigment concentration similar to that found in chlorotic cultures. Ultrastructural examination showed that the conditioned medium induced thylakoid membrane disorganization, typical of chlorotic cells, in nutrient-replete cultures. An active extract was obtained and investigations showed that activity was retained after heating and after addition of an apolar solvent. This indicates that activity of the conditioned medium from chlorotic cells results from non-protein, apolar compound(s).

2012-10-01

The increasingly diverse multicultural and multigenerational student population in the United States requires that educators at all levels develop cultural knowledge, awareness, and sensitivity to help diverse learners fulfill their potential and to avoid cultural misunderstandings that can become obstacles or barriers to learning. The purpose of this study was to design and implement eclectic, creative, evidence-based interdisciplinary educational activities, along with culturally congruent teaching strategies, within a semester-long university course that promoted positive and culturally competent learning outcomes for culturally diverse, largely millennial students. The interdisciplinary course would prepare health professional students with the requisite knowledge and skills, through transformative learning that produces change agents, to provide culturally congruent and quality team-based care to diverse populations. This was a qualitative and quantitative study, which measured students' level of cultural awareness, competence, and proficiency pre and post the educational intervention. Instruments used for data collection included the Inventory for Assessing The Process of Cultural Competence-Student Version (IAPCC-SV) by Campinha-Bacote, course evaluations, students' feedback, and portfolio reflections. The study was conducted at a private academic institution located in the Mid-Atlantic region and the sample population included inter-professional students (N=106) from various health professions including nursing, pharmacy, and allied health sciences. Results from the pre- and post-test IAPCC-SV survey revealed that mean scores increased significantly from pre-test (60.8) to post-test (70.6). Thus, students' levels of cultural competency (awareness, knowledge, skills, desire, encounter) improved post-educational intervention, indicating that the teaching methods used in the course might be applied on a larger scale across the university system to cater to the

Ahmad, Nisar; Abbasi, Bilal Haider; Fazal, Hina

2016-03-01

In the present study, the effect of different in vitro cultures (callus, in vitro shoots) and commercially available peppercorn extract was investigated for its activity against toxic metabolite-producing strains (Escherichia coli, Pseudomonas aeroginosa, Salmonella typhi, Bacillus subtilis, Bacillus cereus, Staphylococcus aureus, and Candida albicans). These in vitro cultures were extracted with ethanol, hexane, and chloroform, and the antipathogenic activity was determined by well-diffusion method. Hexane extract of callus showed 22 mm zone of inhibition against B. cereus, 23 mm against S. aureus, while regenerated shoots and seeds have shown 24.3 and 26 mm zones of inhibition. The ethanolic extracts of regenerated Piper shoots have shown 25 mm activity against S. aureus, 21 mm against B. cereus, and 16 mm in the case of C. albicans in comparison with standard antibiotics. Peppercorn extracts in chloroform and ethanol had shown activities against B. cereus (23.6 mm) and B. subtilis (23.5 mm). During in vitro organogenesis and morphogenesis, cells and tissues produced a comparable phytochemicals profile like mother plant. Morphogenesis is critically controlled by the application of exogenous plant-growth regulators. Such addition alters the hormonal transduction pathways, and cells under in vitro conditions regenerate tissues, which are dependant on the physiological state of cells, and finally enhance the production of secondary metabolites. To the best of our knowledge, this is the first report to compare the antimicrobial potential of in vitro regenerated tissues and peppercorn with standard antibiotics. In conclusion, most of the extracts showed pronounced activities against all the pathogenic microbes. This is a preliminary work, and the minimum inhibitory concentration values needs to be further explored. Regenerated tissues of P. nigrum are a good source of biologically active metabolites for antimicrobial activities, and callus culture presented itself as

On some methods to produce high-energy polarized electron beams by means of proton synchrotrons

1980-01-01

Some methods of production of high-energy polarized electron beams by means of proton synchrotrons are considered. These methods are based on transfer by protons of a part of their energy to the polarized electrons of a thin target placed inside the working volume of the synchrotron. It is suggested to use as a polarized electron target a magnetized crystalline iron in which proton channeling is realized, polarized atomic beams and the polarized plasma. It is shown that by this method one can produce polarized electron beams with energy approximately 100 GeV, energy spread +- 5 % and intensity approximately 10 7 electron/c, polarization approximately 30% and with intensity approximately 10 4 -10 5 electron/c, polarization approximately 100% [ru

The paper presents a description of a method to produce capacitors in integrated circuits that consists in implanting weakly doped silicon with the same impurity, then subjecting it to annealing (producing the inner plate) and implanting it again with ions of neutral elements to produce the dielectric layer. Results of the testing capacitors produced that way are also presented. Unit capacity of C u = 4.5 nF/mm 2 at tgδ = 0.01 has been obtained. The authors are of the opinion that the interesting problem of discontinuous variations of dielectric losses and capacities considered as functions of temperature, must be viewed as an open problem.

The Culture-Free Self-Esteem Inventory (CFSEI-2) was administered to 7 groups of children: 84 White Catholic school students from a New Orleans suburb, 78 White rural public school students from Virginia, 62 Hispanic Migrant student from Florida, 90 Aboriginal and White students from an isolated Canadian community, 199 African American students attending an inner city school, 60 Hispanic and White international students from Venezuela, and 61 Innuit students from isolated community in Labrador. The four elder groups also wrote three words to describe themselves (the Adjective Generation Technique [AGT]). Significant differences in responding between groups were found on all CFSEI-2 scales and for AGT favorability means. Although several possible reasons for these results are discussed, we conclude that the CFSEI-2 is not culture-free. Recommendations are: change the title of the test to avoid misrepresentation, limit test usage to elementary school children, develop an adolescent version with age appropriate language, and construct local norms before using the CFSEI-2 to make decisions about a child's self-esteem. To determine relevance of scores, a team of professionals and lay persons should review items from this or any test given to children who may be different from the normative or standardization group.

Plant cell tissue culture: A potential source of chemicals

Energy Technology Data Exchange (ETDEWEB)

Scott, C.D.; Dougall, D.K.

1987-08-01

Higher plants produce many industrially important products. Among these are drugs and medicinal chemicals, essential oils and flavors, vegetable oils and fats, fine and specialty chemicals, and even some commodity chemicals. Although, currently, whole-plant extraction is the primary means of harvesting these materials, the advent of plant cell tissue culture could be a much more effective method of producing many types of phytochemicals. The use of immobilized plant cells in an advanced bioreactor configuration with excretion of the product into the reactor medium may represent the most straightforward way of commercializing such techniques for lower-value chemicals. Important research and development opportunities in this area include screening for plant cultures for nonmedical, lower-value chemicals; understanding and controlling plant cell physiology and biochemistry; optimizing effective immobilization methods; developing more efficient bioreactor concepts; and perfecting product extraction and purification techniques. 62 refs., 2 figs.

Cultural neuroscience and psychopathology: prospects for cultural psychiatry.

Science.gov (United States)

Choudhury, Suparna; Kirmayer, Laurence J

2009-01-01

There is a long tradition that seeks to understand the impact of culture on the causes, form, treatment, and outcome of psychiatric disorders. An early, colonialist literature attributed cultural characteristics and variations in psychopathology and behavior to deficiencies in the brains of colonized peoples. Contemporary research in social and cultural neuroscience holds the promise of moving beyond these invidious comparisons to a more sophisticated understanding of cultural variations in brain function relevant to psychiatry. To achieve this, however, we need better models of the nature of psychopathology and of culture itself. Culture is not simply a set of traits or characteristics shared by people with a common geographic, historical, or ethnic background. Current anthropology understands culture as fluid, flexible systems of discourse, institutions, and practices, which individuals actively use for self-fashioning and social positioning. Globalization introduces new cultural dynamics and demands that we rethink culture in relation to a wider domain of evolving identities, knowledge, and practice. Psychopathology is not reducible to brain dysfunction in either its causes, mechanisms, or expression. In addition to neuropsychiatric disorders, the problems that people bring to psychiatrists may result from disorders in cognition, the personal and social meanings of experience, and the dynamics of interpersonal interactions or social systems and institutions. The shifting meanings of culture and psychopathology have implications for efforts to apply cultural neuroscience to psychiatry. We consider how cultural neuroscience can refine use of culture and its role in psychopathology using the example of adolescent aggression as a symptom of conduct disorder.

Full Text Available This article provides an overview over the evolution of thinking about "culture" in the work of Raymond Williams. With the introduction of Antonio Gramsci's concept of hegemony culture came to be understood as consisting of not only shared, but contested meanings as well. On the basis of this redefinition by Williams, cultural studies was able to delineate culture as the production, circulation, and consumption of meanings that become embodied and embedded in social practice.

The production of extracellular polysaccharides is studied with Nostoc sp (cyanophycus), Porphiridium cruentum, Rhodosorus marinus, Rhodella maculata (rhodophyci) and Chlamydomonas mexicana (chlorophycus). The polysaccharides produced are separated by centrifugation of the culture then precipitation with alcohol. Their chemical structure was studied by infrared spectrometry and acid hydrolysis. By their rheological properties and especially their insensitivity to temperatrure and pH variations the polysaccharides produced by Porphryridium cruentum and Rhodella maculata appear as suitable candidates for industrial applications.

2000-01-01

The perfusion culture system using a shaken ceramic membrane flask (SCMF) was employed to accumulate microorganisms separated from river water and to produce poly-beta-hydroxybutyric acid (PHB). Using a two-step culture method with a single SCMF, river microorganisms were cultured by separately feeding four representative carbon sources, n-propanol, lactic acid, methanol, and formic acid. After 140 h culture, the cell concentration and PHB content respectively reached 43 g/l and 35% when a propanol medium was fed. Using a two-stage perfusion culture with twin SCMFs, the seed cell mass was increased in the first SCMF and then supplied to the second flask for PHB production. As a consequence, the cellular PHB content rose to 51% in the second SCMF, while the cell concentration gradually increased to 25 g/l after 175 h perfusion culture. These results demonstrated the utility of the two-stage perfusion culture system for developing a cheap means of producing PHB coincident with wastewater treatment.

Critical parameters influencing somatic embryogenesis include growth regulators and oxygen supply. Consequently, the present investigation has focused on optimization of a somatic embryogenic system for peanut (Arachis hypogaea L.) through media supplementation with the auxin, picloram. The latter at 30 mg L(-1) was optimal for inducing regeneration of somatic embryos from cultured explants of zygotic embryos. In contrast, somatic embryogenesis did not occur in the absence of this growth regulator. An assessment has also been made of the beneficial effect on somatic embryogenesis and plant regeneration of the commercial hemoglobin (Hb) solution, Erythrogen. Hemoglobin at 1:50 and 1:100 (v:v) stimulated increases in mean fresh weight (up to a maximum of 57% over control), mean number of explants producing somatic embryos (15%) and mean number of somatic embryos per explant (29%).

Culture and social class.

Science.gov (United States)

Miyamoto, Yuri

2017-12-01

A large body of research in Western cultures has demonstrated the psychological and health effects of social class. This review outlines a cultural psychological approach to social stratification by comparing psychological and health manifestations of social class across Western and East Asian cultures. These comparisons suggest that cultural meaning systems shape how people make meaning and respond to material/structural conditions associated with social class, thereby leading to culturally divergent manifestations of social class. Specifically, unlike their counterparts in Western cultures, individuals of high social class in East Asian cultures tend to show high conformity and other-orientated psychological attributes. In addition, cultures differ in how social class impacts health (i.e. on which bases, through which pathways, and to what extent). Copyright © 2017 Elsevier Ltd. All rights reserved.

Full Text Available This article aims to promote, given the current reality, in which it sets up a scenario marked by breaking cultural boundaries and understand the world as a more unified universe, reflect on existing conceptions of culture in this context. The world increasingly marked by multicultural societies, the weakening of old cultural references and the multiplication of identity statements. The teaching of foreign languages is an opportunity to place the student in planetary universe of an apparent online culture, but which increasingly reinforces different identities. In this sense, the article presented here, and promote space for a discussion of these very contemporary issues, presents the analysis of a survey of two of the four textbooks in Spanish, selected to join the National Book Program for Education East, delimiting the choice of the characteristics of space and time for analysis and construction of this writing: El arte de leer Spanish and Síntesis: course española language. Not the total analysis of the books will be presented, opting to make a cut, taking as a criterion some teaching units and activities more targeted to the theme proposed, in addition to meet the rules and brevity of this article. Such research revolved around the following questions: How do the textbooks for the teaching and learning of Spanish produced in Brazil include: a the cultural diversity of the Hispanic world? ; b the claim - with respect to their community in training and socializing (s of identity (s American latina- (s? ; and c interaction - proposal from learning strategies, with the identity formation of the Brazilian student? Therefore, we adopted the methodology of qualitative analysis and content analysis technique, taking as indicators the following categories: geographical areas and cultural areas explored in the texts; the identities of anonymous characters and famous circulating in the books; and educational activities related to cultural issues

Narrating horror: the horror film as cultural construct

This thesis examines horror films through an application of cultural analysis (primarily the work of Pierre Bourdieu) to selected texts in order to answer critics employing psychoanalytic perspectives to horror. It argues that psychoanalysis misses much of the heart of horror texts through its claims that textual 'meaning' lies within individuals rather than in the society in which horror texts were produced.\\ud Bourdieu's hypotheses are applied to films, along with the work of more specific ...

This article summarizes the definitions, means, and research of adapting psychotherapy to clients' cultural backgrounds. We begin by reviewing the prevailing definitions of cultural adaptation and providing a clinical example. We present an original meta-analysis of 65 experimental and quasi-experimental studies involving 8,620 participants. The omnibus effect size of d = .46 indicates that treatments specifically adapted for clients of color were moderately more effective with that clientele than traditional treatments. The most effective treatments tended to be those with greater numbers of cultural adaptations. Mental health services targeted to a specific cultural group were several times more effective than those provided to clients from a variety of cultural backgrounds. We recommend a series of research-supported therapeutic practices that account for clients' culture, with culture-specific treatments being more effective than generally culture-sensitive treatments. © 2010 Wiley Periodicals, Inc.

Cloning whole animals with somatic cells as parents offers the possibility of targeted genetic manipulations in vitro such as “gene knock-out” by homologous recombination. However, such manipulation requires prolonged culture of nuclear donor cells. Previous successes in cloning have been limited to the use of cells collected either fresh or after short-term culture. Therefore, demonstration of genetic totipotency of cells after prolonged culture is pivotal to combining site-specific genetic manipulations and cloning. Here we report birth of six clones of an aged (17-year-old) Japanese Black Beef bull using ear skin fibroblast cells as nuclear donor cells after up to 3 months of in vitro culture (10–15 passages). We observed higher developmental rates for embryos derived from later passages (10 and 15) as compared with those embryos from an early passage (passage 5). The four surviving clones are now 10–12 months of age and appear normal, similar to their naturally reproduced peers. These data show that fibroblasts of aged animals remain competent for cloning, and prolonged culture does not affect the cloning competence of adult somatic donor cells. PMID:10655472

Culture-specific delusions. Sense and nonsense in cultural context.

Science.gov (United States)

Gaines, A D

1995-06-01

It can be said that a definition of delusions requires the invocation of cultural understandings, standards of acceptability, as well as conceptions of reality and the forces that animate it. For these reasons, the determination of delusional or normative ideation can only be effected properly within particular cultural contexts. The cross-cultural record suggests that it is difficult to separate the delusional from the cultural; a belief that is patterened and culturally specific is, by definition a cultural, not a delusional belief. One must rely upon particular, relevant local cultural understandings to ascertain when the bounds of culture have been transgressed and meaning has given way to unshareable nonsense.

Effect of culture medium on polymer production and temperature on recovery of polymer produced from newly identified Rhyzopus oryzae ST29

2008-04-01

Full Text Available Thermotolerant fungal isolate ST29 was identified by observing on cell morphology and molecular technique based on internal transcribed spacer (ITS gene to be Rhizopus oryzae. Among four culture media tested, the strain exhibited the highest growth in yeast malt extract (YM medium (4.87 g/l, followed by Sabouraud dextrose broth (SDB (4.25 g/l, potato dextrose broth (PDB (4.10 g/l and palm oil mill effluent (POME (3.29 g/l, respectively, after 4 days cultivation at 45oC. However, the strain was found to produce polymer only in POME medium at 45oC, but not in the three synthetic media tested. Effect of temperature on separation of the biopolymer produced by this fungal strain was studied by incubating the culture broth in water bath with temperatures in the range of room temperature to 70oC. The biopolymer was recovered by filtration, centrifugation, and precipitation by adding 4 volumes of 95% ethanol, then freeze-drying. These temperatures therefore had no influence on the biopolymer yields (5.58-5.78 g/l or on biomass yields (2.90-3.29 g/l.

This research was conducted to identify culturable surfactant-producing bacterial species that inhabit the 40,000-year-old natural asphalt seep at the Rancho La Brea Tar Pits in Los Angeles, CA. Using phenanthrene, monocyclic aromatic hydrocarbons, and tryptic soy broth as growth substrates, culturable bacteria from the tar pits yielded ten isolates, of which three species of gamma-proteobacteria produced biosurfactants that accumulated in spent culture medium. Partially purified biosurfactants produced by these strains lowered the surface tension of water from 70 to 35-55 mN/m and two of the biosurfactants produced 'dark halos' with the atomized oil assay, a phenomenon previously observed only with synthetic surfactants. Key findings include the isolation of culturable biosurfactant-producing bacteria that comprise a relatively small fraction of the petroleum-degrading community in the asphalt.

Culture-sensitive psychotraumatology

Ulrich Schnyder

2016-07-01

Full Text Available Background: Although there is some evidence of the posttraumatic stress disorder (PTSD construct's cross cultural validity, trauma-related disorders may vary across cultures, and the same may be true for treatments that address such conditions. Experienced therapists tailor psychotherapy to each patient's particular situation, to the nature of the patient's psychopathology, to the stage of therapy, and so on. In addition, culture-sensitive psychotherapists try to understand how culture enhances the meaning of their patient's life history, the cultural components of their illness and help-seeking behaviors, as well as their expectations with regard to treatment. We cannot take for granted that all treatment-seeking trauma survivors speak our language or share our cultural values. Therefore, we need to increase our cultural competencies. Methods: The authors of this article are clinicians and/or researchers from across the globe, working with trauma survivors in various settings. Each author focused on one or more specific cultural aspects of working with trauma survivors and highlighted the following aspects. Results: As a result of culture-specific individual and collective meanings linked to trauma and trauma-related disorders survivors may be exposed to (self-stigma in the aftermath of trauma. Patients who are reluctant to talk about their traumatic experiences may instead be willing to write or use other ways of accessing the painful memories such as drawing. In other cultures, community and family cohesion are crucial elements of recovery. While awareness of culture-specific aspects is important, we also need to beware of premature cultural stereotyping. When disseminating empirically supported psychotherapies for PTSD across cultures, a number of additional challenges need to be taken into account: many low and middle income countries have very limited resources available and suffer from a poor health infrastructure. Conclusions: In summary

Making Material and Cultural Connections: the fluid meaning of ‘Living Electrically’ in Japan and Canada 1920–1960

Directory of Open Access Journals (Sweden)

Heather Chappells

2018-05-01

Full Text Available This article explores how material and cultural ‘connections’ to households were crucial in defining historical pathways of domestic electrification in Canada and Japan. Though relatively overlooked in the history of energy, we contend that the intricacies of household connections are important in understanding convergence and divergence in electrified ways of life. Electricity’s arrival in urban and rural homes was an uneven process in part due to geographical diversity and the variable connection policies of public or private providers. Selective insights from our two countries show that spatial irregularities in grid expansion and social inequities in the meaning of electrical service further arose out of misalignments between developers’ visions and the diverse material cultures of households. This disparity manifested in the form of disconnections between non-standard wiring and equipment, as well as in the form of consumer resistance, protests and even illicit acts as people fought to get the electrical service they desired. Instead of seeing electrification as a single, universal ideal around which all countries eventually converged, we conclude that it has always been an open-ended, negotiable and culturally fluid process.

2007-02-01

Pregnancy encompasses socio-cultural, historical, and affective dimensions that process various meanings in women's bodies. Each society constructs popular concepts, practices, and explanatory models that differ from the biomedical model and aim to protect the mother and fetus and foster a healthy pregnancy. This qualitative study, based on interpretative anthropology, unveils the experiences of 27 poor women and their repercussions on the malnutrition of their infants, treated at a Childhood Malnutrition Treatment Center in Fortaleza, Northeast Brazil. From January to June 2004, ethnographic and narrative interviews were conducted on so-called "birth weakness", in addition to participant observation of outpatient, nursing, and home childcare. The mothers believed that their own physical and emotional suffering and precarious nutritional status were "imprinted" on the fetus, resulting in the child's malnutrition. While the ethno-etiology of "weakness" points to factors outside the body that involuntarily affect the pregnant mother, the medical view tended to incriminate the mother herself. It is necessary to understand the mothers' narratives, sympathize with their suffering, and spawn a closer approach between the popular and biomedical concepts.

Identity and meaning in life are core developmental assets in emerging adulthood. We analysed how religiosity is related to these intentional strivings in emerging adults enrolled in theological education, by depicting (1) identity strivings and meaning in life accounts in faith narratives (Study 1) and (2) links between personal identity and meaning in life profiles and religious beliefs, behaviours, and subjective experiences (Study 2). Both studies highlighted that a Foreclosed status, with high personal commitment and reduced exploration, was dominant in faith narratives and personal identity profiles. Also, in narratives meaning in life was reflected by a strong focus on presence of meaning through religious insights. Nonetheless, global meaning in life profiles indicated that many emerging adults were searching for a meaning in their lives, while reporting lower levels of presence of meaning. Identity Achievement and High Presence-High Search profiles were linked to the highest levels of subjective, behavioural, and cognitive religiosity. We highlighted the multidimensionality of identity and meaning in life strivings in emerging adults attending theological schools. We pointed out that even in a somewhat foreclosed cultural context (e.g., Romanian Christian Orthodox theological schools), religion represents a dynamic social and ideological context for self-development. Statement of contribution What is already known on this subject? Religious beliefs increase in emerging adults, doubled by decreases in religious behaviours, linked to an adherence to a more personal approach to religion. Religious youth are more committed to their faith and also explore identity and life meaning in relation to their religious strivings. Youth religious exemplars report close links between their religious faith and strivings for meaningful life goals. What does this study add? We investigated Christian Orthodox theology students, for whom religion is a normative dimension of

Kitaya, Yoshiaki; Yano, Sachiko; Hirai, Hiroaki

The long term human life support in space is greatly dependent on the amounts of food, atmospheric O2 and clean water produced by plants. Therefore, the bio-regenerative life support system such as space farming with scheduling of crop production, obtaining high yields with a rapid turnover rate, converting atmospheric CO2 to O2 and purifying water should be established with employing suitable plant species and varieties and precisely controlling environmental variables around plants grown at a high density in a limited space. We are developing a sweetpotato culture system for producing tuberous roots as a high-calorie food and fresh edible leaves and stems as a nutritive functional vegetable food in space. In this study, we investigated the ability of food production, CO2 to O2 conversion through photosynthesis, and clean water production through transpiration in the sweetpotato production system. The biomass of edible parts in the whole plant was almost 100%. The proportion of the top (leaves and stems) and tuberous roots was strongly affected by environmental variables even when the total biomass production was mostly the same. The production of biomass and clean water was controllable especially by light, atmospheric CO2 and moisture and gas regimes in the root zone. It was confirmed that sweetpotato can be utilized for the vegetable crop as well as the root crop allowing a little waste and is a promising functional crop for supporting long-duration human activity in space.

Jean Baudrillard ise, tüketimi kodlar ve kurallarla düzenlenmiş bir göstergeler sistemi olarak tanımlamaktadır. Tüketim tarzları kişilerin kimliklerinin birer unsuru haline gelmektedir. Özneler kimliklerini ifade etmek amacıyla metaları kullanmakta ve kişilerin toplum içindeki statüsü tükettikleri ile ölçülür hale gelmektedir. TV dizileri de, bireylere tüketilecek sonsuz nesneler yoluyla oluşturulacak yaşam tarzları ile ilgili bilgiler vermektedir. Çalışmada, seçilen on dizide üretilen anlam dünyası, yeniden üretilen tüketim ideolojisi ve oluşturulan kadın ve erkek rol modelleri çözümlenmektir. The Re-produced Consumption Culture by TV Series The concept of consumption means ‘to destroy, spend, waste or finish something’. Jean Baudrillard describes the consumption as a semiotic system regulated of codes and rules. Consumption styles are nowadays becoming an element of people’s identity. Individuals use the commodities to express their identities and therefore the status of people in the community being measured according to what they consume. Meanwhile many TV series provides information to individuals about lifestyles to be created by infinite items consumed. This study analyzes the mindset created in ten selected TV series and the re-produced ideology of consumption as well as the presented role models for women and men in them.

Cybersemiotics: A suggestion for a transdisciplinary framework for description of observing, anticipatory and meaning producing systems

Science.gov (United States)

Brier, Soren

1998-07-01

The ability of systems to be anticipatory seems to be intricate connected with the ability to observe and to cognate by reducing complexity through signification. The semantic capacity of living systems, the cognitive ability to assign meaning to differences perturbating the system's self-organization, seems to be the prerequisite for the phenomenon of communication, language and consciousness. In cybernetics Bateson developed the idea that information is a difference that makes a difference and second order cybernetics developed the concept of organisms as self-organized and self-produced systems (autopoietic) as the prerequisite of life and cognition. The cognitive ability seems to be qualitative different from what so far is computable on any known machine although parts of different aspects of the process can be partly simulated in AI, neutral network and AL. In semiotics the fundamental process of cognition and communication is called semiosis or signification and C. S. Peirce created a special triadic, objective idealistic, pragmatic and evolutionary philosophy to be able to give a fruitful description of the process and its relation to logic and the concept of natural law. Both second order cybernetics and semiotics sees information and meaning as something produced by individual organisms through structural couplings to the environments or other individuals through historical drift and further developed in social communication. Luhmann points out that social communication also only functions through structural couplings which he calls generalized media such as science, art, power, love and money. Peirce talks of the semiotic net as a triadic view of meanings developing through history and in animals through evolution. In accordance with this Wittgenstein points out that signification is created in language games developed in specific life forms. Life forms are the things we do in society such as seducing, commanding and explaining. As animals do not have

Organizational culture is key to the successful implementation of major improvement strategies. Transformation to a patient-centered medical home (PCHM) is such an improvement strategy, requiring a shift from provider-centric care to team-based care. Because this shift may impact provider satisfaction, it is important to understand the relationship between provider satisfaction and organizational culture, specifically in the context of practices that have transformed to a PCMH model. This was a cross-sectional study of surveys conducted in 2011 among providers and staff in 10 primary care clinics implementing their version of a PCMH: Care by Design. Measures included the Organizational Culture Assessment Instrument and the American Medical Group Association provider satisfaction survey. Providers were most satisfied with quality of care (mean, 4.14; scale of 1-5) and interactions with patients (mean, 4.12) and were least satisfied with time spent working (mean, 3.47), paperwork (mean, 3.45), and compensation (mean, 3.35). Culture profiles differed across clinics, with family/clan and hierarchical cultures the most common. Significant correlations (P ≤ .05) between provider satisfaction and clinic culture archetypes included family/clan culture negatively correlated with administrative work; entrepreneurial culture positively correlated with the Time Spent Working dimension; market/rational culture positively correlated with how practices were facing economic and strategic challenges; and hierarchical culture negatively correlated with the Relationships with Staff and Resource dimensions. Provider satisfaction is an important metric for assessing experiences with features of a PCMH model. Identification of clinic-specific culture archetypes and archetype associations with provider satisfaction can help inform practice redesign. Attention to effective methods for changing organizational culture is recommended.

Silence, nostalgia, violence, poverty … : what does 'culture' mean for South African sexuality educators?

Science.gov (United States)

Depalma, Renée; Francis, Dennis

2014-01-01

In in-depth interviews with 25 Life Orientation teachers in South Africa, we found that teachers spontaneously drew upon notions of culture to explain and justify people's sexual beliefs and behaviours and their own role as educators. Drawing upon a Bakhtinian understanding of discourse, we apply critical semantic analysis to explore how culture is deployed as a discursive strategy. Teachers draw upon particular understandings of culture available to them in their social contexts. Furthermore, the substitution of the word 'culture' for a series of other phenomena (silence, violence and poverty) affords these phenomena a certain authority that they would otherwise not wield. We argue, first, that systems teacher education and training needs to (re)define culture as dynamic, interactive and responding to, but not determined by, socio-historical realities. Beyond this, teachers need to learn how to critically engage with cultural practices and perceptions and to be provided with some basic tools to do so, including more sophisticated understandings of cultural and training in dialogic methodologies. Teaching sexuality education in multicultural societies such as South Africa will require meaningful engagement in intercultural dialogues that may need to include voices that have traditionally been excluded from school spaces.

Moments of joy and delight: the meaning of traditional food in dementia care.

Science.gov (United States)

Hanssen, Ingrid; Kuven, Britt Moene

2016-03-01

To learn about the meaning of traditional food to institutionalised patients with dementia. Traditional food strengthens the feelings of belonging, identity and heritage, which help persons with dementia to hold on to and reinforce their cultural identity and quality of life. Taste is more cultural than physiological. Dietary habits are established early in life and may be difficult to change. Being served unfamiliar dishes may lead to disappointment and a feeling of being betrayed and unloved. The three studies presented have a qualitative design. In-depth interviews of family members and nurses experienced in dementia care were conducted in South Africa and among ethnic Norwegians and the Sami in Norway. Content-focused analysis, hermeneutic in character, was used to enable the exploration of the thoughts, feelings and cultural meaning described. Traditional foods created a feeling of belonging and joy. Familiar tastes and smells awoke pleasant memories in patients and boosted their sense of well-being, identity and belonging, even producing words in those who usually did not speak. In persons with dementia, dishes remembered from their childhood may help maintain and strengthen cultural identity, create joy and increase patients' feeling of belonging, being respected and cared for. Traditional food furthermore improves patients' appetite, nutritional intake and quality of life. To serve traditional meals in nursing homes demands extra planning and resources, traditional knowledge, creativity and knowledge of patients' personal tastes. This study provides insight into culture-sensitive dietary needs of institutionalised patients with dementia. The cultural significance of food for feeling contentment and social and physical well-being is discussed. Besides helping to avoid undernutrition, being served traditional dishes may be very important to reminiscence, joy, thriving and quality of life. © 2016 John Wiley & Sons Ltd.

Aging in culture.

Fung, Helene H

2013-06-01

This article reviews the empirical studies that test socioemotional aging across cultures. The review focuses on comparisons between Western (mostly North Americans and Germans) and Eastern cultures (mostly Chinese) in areas including age-related personality, social relationships, and cognition. Based on the review, I argue that aging is a meaning-making process. Individuals from each cultural context internalize cultural values with age. These internalized cultural values become goals that guide adult development. When individuals from different cultures each pursue their own goals with age, cultural differences in socioemotional aging occur.

Strategies for efficiently selecting PHA producing mixed microbial cultures using complex feedstocks: Feast and famine regime and uncoupled carbon and nitrogen availabilities.

Science.gov (United States)

Oliveira, Catarina S S; Silva, Carlos E; Carvalho, Gilda; Reis, Maria A

2017-07-25

Production of polyhydroxyalkanoates (PHAs) by open mixed microbial cultures (MMCs) has been attracting increasing interest as an alternative technology to PHA production by pure cultures, due to the potential for lower costs associated with the use of open systems (eliminating the requirement for sterile conditions) and the utilisation of cheap feedstock (industrial and agricultural wastes). Such technology relies on the efficient selection of an MMC enriched in PHA-accumulating organisms. Fermented cheese whey, a protein-rich complex feedstock, has been used previously to produce PHA using the feast and famine regime for selection of PHA accumulating cultures. While this selection strategy was found efficient when operated at relatively low organic loading rate (OLR, 2g-CODL -1 d -1 ), great instability and low selection efficiency of PHA accumulating organisms were observed when higher OLR (ca. 6g-CODL -1 d -1 ) was applied. High organic loading is desirable as a means to enhance PHA productivity. In the present study, a new selection strategy was tested with the aim of improving selection for high OLR. It was based on uncoupling carbon and nitrogen supply and was implemented and compared with the conventional feast and famine strategy. For this, two selection reactors were fed with fermented cheese whey applying an OLR of ca. 8.5g-CODL -1 (with 3.8g-CODL -1 resulting from organic acids and ethanol), and operated in parallel under similar conditions, except for the timing of nitrogen supplementation. Whereas in the conventional strategy nitrogen and carbon substrates were added simultaneously at the beginning of the cycle, in the uncoupled substrates strategy, nitrogen addition was delayed to the end of the feast phase (i.e. after exogenous carbon was exhausted). The two different strategies selected different PHA-storing microbial communities, dominated by Corynebacterium and a Xantomonadaceae, respectively with the conventional and the new approaches. The new

2008-01-01

Full Text Available The objective of the study was to investigate efficiency of anther culture in the production of spontaneous double haploids from randomly selected heterozygous genotypes of wheat (Triticum aestivum L.. Anthers of 20 F1 wheat combinations were grown in vitro on a modified Potato-2 medium. All of the examined genotypes have shown the ability to produce pollen calluses as well as to regenerate green plants. On average for the whole experiment material, 47.2 calluses were produced per 100 cultured anthers. The green plant regeneration ranged from 0.8 to 13.4 green plants per spike, with an overall mean of 5.8. From the total of 582 regenerated green plants, 47.9% (279 were spontaneous double haploids. The final average yield from the study was 2.8 double haploids per spike.

OVERCOMING THE CULTURAL DIFFERENCES: PARABLE AS A MEANS OF INTERCULTURAL DIALOGUE

2013-09-01

Full Text Available Purpose. This article attempts to investigate the ways to overcome negative after-effects of intercultural communication. Methodology and theoretical results: To avoid the negative after-effects of intercultural communication caused by the clash of different reality tunnels, it is necessary to go beyond the framework of the specific symbolical territory, which is seen as the only true reality. Expanding the horizons of life, going beyond the boundaries of a personal reality tunnel can be achieved, in particular, by using parables. Acquaintance with parables helps to extend the set of the world perception models and to change the positions of the communication process participants. Parables act as intermediaries between people of different cultures and mentalities. Owing to its archetypical form, parable becomes one of the most popular narratives illustrating deep and multi-faceted truths that sometimes cannot be expressed by any other way. Parable serves as an open and flexible model of the world and a model of an individual "I self". This model helps people to constitute themselves as a part of their world. Parable requires to reject its interpretation in the oppositions inherent in a given culture and to reconsider the very way of understanding. Rejection of the oppositions provides the possibility of perceiving the world as integrity, unity in diversity, helps to overcome one-sided picture of the inner world of a man and his life in society. Understanding of a parable works towards changing personal position, and human creative nature is actualized. Conclusion: Parables uniquely reflect the real world and contribute to personal understanding of reality. Parables are successfully transplanted into different cultures operating as heritage of a culture-recipient and as a connecting link, which optimizes an intercultural dialogue.

Background Although there is some evidence of the posttraumatic stress disorder (PTSD) construct's cross cultural validity, trauma-related disorders may vary across cultures, and the same may be true for treatments that address such conditions. Experienced therapists tailor psychotherapy to each patient's particular situation, to the nature of the patient's psychopathology, to the stage of therapy, and so on. In addition, culture-sensitive psychotherapists try to understand how culture enhances the meaning of their patient's life history, the cultural components of their illness and help-seeking behaviors, as well as their expectations with regard to treatment. We cannot take for granted that all treatment-seeking trauma survivors speak our language or share our cultural values. Therefore, we need to increase our cultural competencies. Methods The authors of this article are clinicians and/or researchers from across the globe, working with trauma survivors in various settings. Each author focused on one or more specific cultural aspects of working with trauma survivors and highlighted the following aspects. Results As a result of culture-specific individual and collective meanings linked to trauma and trauma-related disorders survivors may be exposed to (self-)stigma in the aftermath of trauma. Patients who are reluctant to talk about their traumatic experiences may instead be willing to write or use other ways of accessing the painful memories such as drawing. In other cultures, community and family cohesion are crucial elements of recovery. While awareness of culture-specific aspects is important, we also need to beware of premature cultural stereotyping. When disseminating empirically supported psychotherapies for PTSD across cultures, a number of additional challenges need to be taken into account: many low and middle income countries have very limited resources available and suffer from a poor health infrastructure. Conclusions In summary, culture

BRIDGING THE COMPETING VIEWS OF EUROPEAN CULTURAL INTEGRATION: THE TRANSFORMATIVE VIEW OF CULTURE AS A MEANS TO PROMOTE GROWTH, EMPLOYMENT AND SOCIAL COHESION

Directory of Open Access Journals (Sweden)

María Luz SUÁREZ CASTIÑEIRA

2018-05-01

Full Text Available The concept of a European culture became very complex with the enlargement of 2004 towards the East, when the EU, as Delanty pointed out, moved “beyond postnationality to an encounter with multiple civilizational forms,” multiple histories and competing visions of European integration. The “unity-in-diversity” paradigm turned into a huge challenge for the European institutions. On the one hand, achieving a European image of cultural unity without excluding all the local, regional and national cultures is a very complex, if not impossible, task. On the othe hand, culture remains an ambiguous term in European institutions due to the lack of a full-fledged European cultural policy. This paper focuses first on how in the early 1970s the EC/EU started to be concerned with defining the role of culture, and second on how since the year 2000 culture has progressively acquired a new status with potentially transformative powers to bridge the competing views of cultural integration. Programmes, such as the “2014-2020 Creative Europe” programme, focus on culture as a creative accelerator and promotor of different forms of cultural participation and production. Culture generates “smart, sustainable and inclusive growth”, and contributes to “high employment, high productivity, and high social cohesion.”

Lagooning microbial fuel cells: A first approach by coupling electricity-producing microorganisms and algae

Highlights: • An algae cathode of a MFC has been used without artificial mediators or catalysts. • To perform a lagooning wastewater treatment coupled with energy-producing MFC. • The producing electricity operates under day/night irradiation cycles, is shown. - Abstract: The paper focused on the start-up and performance characterisation of a new type of microbial fuel cell (MFC), in which an algae culture was seeded in the cathodic chamber to produce the oxygen required to complete the electrochemical reactions of the MFC, thus circumventing the need for a mechanical aerator. The system did not use mediators or high cost catalysts and it can be started-up easily using a straightforward three-stage procedure. The start-up consists of the separate production of the electricity-producing microorganisms and the algae cultures (stage I), replacement of the mechanical aeration system by the algae culture (stage II) and a change in the light dosage from a continuous input to a dynamic day/night profile. The MFC was operated under a regime of 12 h light and 12 h dark and was also operated in batch and continuous substrate-feeding modes. The same cell voltage was achieved when the cathode compartment was operated with air supplied by aerators, which means that this configuration can perform as well as the traditional one. The results also show the influence of both the organic load and light irradiation on electricity production and demonstrate that this type MFC is a robust and promising technology that can be considered as a first approach to perform a lagooning wastewater treatment with microbial fuel cells

A volatile metabolite, 2-methylisoborneol (2-MIB), causes an unpleasant taste and odor in tap water. Some filamentous cyanobacteria produce 2-MIB via a two-step biosynthetic pathway: methylation of geranyl diphosphate (GPP) by methyl transferase (GPPMT), followed by the cyclization of methyl-GPP by monoterpene cyclase (MIBS). We isolated the genes encoding GPPMT and MIBS from Pseudanabaena galeata, a filamentous cyanobacterium known to be a major causal organism of 2-MIB production in Japanese lakes. The predicted amino acid sequence showed high similarity with that of Pseudanabaena limnetica (96% identity in GPPMT and 97% identity in MIBS). P. galeata was cultured at different temperatures to examine the effect of growth conditions on the production of 2-MIB and major metabolites. Gas chromatograph-mass spectrometry (GC-MS) measurements showed higher accumulation of 2-MIB at 30 °C than at 4 °C or 20 °C after 24 h of culture. Real-time-RT PCR analysis showed that the expression levels of the genes encoding GPPMT and MIBS decreased at 4 °C and increased at 30 °C, compared with at 20 °C. Furthermore, metabolite analysis showed dramatic changes in primary metabolite concentrations in cyanobacteria grown at different temperatures. The data indicate that changes in carbon flow in the TCA cycle affect 2-MIB biosynthesis at higher temperatures. Copyright © 2013 Elsevier GmbH. All rights reserved.

Sovie, M D

1993-01-01

Hospitals, to survive, must be transformed into responsive, participative organizations capable of new practices that produce improved results in both quality of care and service at reduced costs. Creating, managing, and changing the culture are critical leadership functions that will enable the hospital to succeed. Strategic planning and effective implementation of planned change will produce the desired culture. Work restructuring, a focus on quality management along with changes in clinical practices, as well as the care and support processes, are all a part of the necessary hospital cultural revolution.

Dignity and autonomy in the care for patients with dementia: Differences among formal caretakers of varied cultural backgrounds and their meaning.

Bentwich, Miriam Ethel; Dickman, Nomy; Oberman, Amitai

A key message in the World Health Organization report on dementia (2012) emphasizes this disease as a top priority in public health and the need to improve professional attitudes to patients with dementia, while acknowledging that the workforce in dementia care is becoming increasingly diverse culturally. To trace whether there are substantial gaps between formal caretakers from different cultural groups (Israeli born Jews [Sabras], Israeli Arabs [Arabs] and migrants from Russia [Russians]) regarding their stances on the human dignity and autonomy of patients with dementia, as well as understand the meaning of these gaps. quantitative analysis utilizing questionnaires that were filled-out by approximately 200 caretakers from the different cultural groups, working in a nursing home or a hospital. In nursing homes, substantial differences were found in the attitudes to human dignity and autonomy of patients with dementia between Russian and Arab as well as Sabra caretakers. In the hospital, there was no influence for the ethno-culture variable on dignity or autonomy. Contrary to past research, in nursing homes, significant differences were found between certain ethno-cultural groups (Arabs and Russians) regarding their stance towards the dignity of patients with dementia. Arab caretakers hold a conception of dignity and autonomy that resonates strongly with person-centered care and outweighs institutional settings as well as may be related to the fostering of virtues.

Cebrian-Serrano, A; Salvador, I; Silvestre, M A

2014-02-01

Currently, in vitro-produced embryos derived by ovum pick up (OPU) and in vitro fertilization (IVF) technologies represent approximately one-third of the embryos worldwide in cattle. Nevertheless, the culture of small groups of embryos from an individual egg donor is an issue that OPU-IVF laboratories have to face. In this work, we tested whether the development and quality of the preimplantation embryos in vitro cultured in low numbers (five embryos) could be improved by the addition of epidermal growth factor, insulin, transferrin and selenium (EGF-ITS) or by the WOW system. With this aim, immature oocytes recovered from slaughtered heifers were in vitro matured and in vitro fertilized. Presumptive zygotes were then randomly cultured in four culture conditions: one large group (LG) (50 embryos/500 μl medium) and three smaller groups [five embryos/50 μl medium without (control) or with EGF-ITS (EGF-ITS) and five embryos per microwell in the WOW system (WOW)]. Embryos cultured in LG showed a greater ability to develop to blastocyst stage than embryos cultured in smaller groups, while the blastocyst rate of WOW group was significantly higher than in control. The number of cells/blastocyst in LG was higher than control or WOW, whereas the apoptosis rate per blastocyst was lower. On the other hand, the addition of EGF-ITS significantly improved both parameters compared to the control and resulted in similar embryo quality to LG. In conclusion, the WOW system improved embryo development, while the addition of EGF-ITS improved the embryo quality when smaller groups of embryos were cultured. © 2013 Blackwell Verlag GmbH.

Environmental impacts of cultured meat production.

Science.gov (United States)

Tuomisto, Hanna L; de Mattos, M Joost Teixeira

2011-07-15

Cultured meat (i.e., meat produced in vitro using tissue engineering techniques) is being developed as a potentially healthier and more efficient alternative to conventional meat. Life cycle assessment (LCA) research method was used for assessing environmental impacts of large-scale cultured meat production. Cyanobacteria hydrolysate was assumed to be used as the nutrient and energy source for muscle cell growth. The results showed that production of 1000 kg cultured meat requires 26-33 GJ energy, 367-521 m(3) water, 190-230 m(2) land, and emits 1900-2240 kg CO(2)-eq GHG emissions. In comparison to conventionally produced European meat, cultured meat involves approximately 7-45% lower energy use (only poultry has lower energy use), 78-96% lower GHG emissions, 99% lower land use, and 82-96% lower water use depending on the product compared. Despite high uncertainty, it is concluded that the overall environmental impacts of cultured meat production are substantially lower than those of conventionally produced meat.

“Fora do Eixo: Estado ou mercado?” Modos de mediação entre produção cultural, política e mercado no Brasil

Directory of Open Access Journals (Sweden)

Victoria Irisarri

2017-01-01

Full Text Available Forms of contemporary cultural production in Brazil have articulated emerging social forms that put strain and open new questions on the boundaries between cultural production, the political and the market. This paper seeks to analyze the relationships between cul- tural production, the market and the political produced by an emerging artistic-cultural movement, Fora do Eixo. This movement emerged in the last decade, and is characterized by its organization in an articulated collective network and the use of digital technologies for work on cultural production. Drawing upon ethnographic work, this paper analyses some of the meanings that Fora do Eixo gives to certain actions of cultural production, transcending the analytical simplifications to understand the modes of mediation among culture, politics and the market that these movements produce in their own terms.

The natural mycobiota occurring in bee pollen is studied in the present report with special attention to analyze the incidence of fungal species that are potential producers of mycotoxins. A total of 90 ready-to-eat bee pollen samples were analyzed. Eighty-seven samples were collected in stores placed in different Spanish areas and three were from Buenos Aires (Argentina). The statistical results (ANOVA) showed that yeasts and Penicillium spp. were the predominant fungi. With regard to the potential mycotoxin producing species, Penicillium verrucosum, Aspergillus niger aggregate, Aspergillus carbonarius, Aspergillus ochraceus, Aspergillus flavus, Aspergillus parasiticus and Alternaria spp. were found. The last genus was isolated very frequently. The potential ability for producing ochratoxin A (OTA) and aflatoxins B(1), B(2), G(1) and G(2) was studied by culturing in vitro the isolates followed by analysis of these mycotoxins in culture extracts by HPLC with fluorescent detection. It was found that 100%, 53.3%, 33.3% and 25% of the isolates of A. carbonarius, A. ochraceus, P. verrucosum and A. niger aggregate, respectively, produced OTA. Moreover, 28.6% of the isolates from the A. flavus plus A. parasiticus group were able to produce aflatoxin B(1). Aflatoxin B(2) was detected in only 10% of the cultures. Aflatoxins G(1) and G(2) were not detected in cultures under the assayed conditions. This is the first report carried out on the natural mycobiota occurring in bee pollen in general and on the toxigenic capability of these isolates in particular.

Wing, D M; Thompson, T

1996-01-01

The purpose of this study was to learn the meaning of alcohol to the traditional Muscogee Creek Indians of eastern Oklahoma. Using Leininger's theory of culture care diversity and universality as the theoretical base, the authors conducted interviews of 24 traditional people to elicit both emic and etic meanings of alcohol. The conceptualization of alcohol as a dichotomy of power to do both good and evil emerged as the central theme. Other meanings of alcohol were explicated in relation to five social structure dimensions. The findings suggest culturally competent nursing implications for preserving, accommodating, and repatterning the meaning of alcohol.

In this study, six bacterial isolates that produced thermo-resistant enzymes isolated from the internal surfaces of raw milk tankers were evaluated for their ability to produce proteolysis within either single culture biofilms or co-culture biofilms. Biofilms were formed in an in vitro model system that simulated the upper internal surface of a raw milk tanker during a typical summer's day of milk collection in New Zealand. The bacterial isolates were further evaluated for their ability to form biofilms at 25, 30 and 37°C. Mutual and competitive effects were observed in some of the co-culture biofilms, with all isolates being able to form biofilms in either single culture or co-culture at the three temperatures. The proteolysis was also evaluated in both biofilms and corresponding planktonic cultures. The proteolysis per cell decreased as the temperature of incubation (20-37°C) increased. Furthermore, mutualistic interactions in terms of proteolysis were observed when cultures were grown as co-culture biofilms. This is the first study to show that proteolytic enzymes can be produced in biofilms on the internal surfaces of raw milk tankers. This has important implications for the cleaning and the temperature control of raw milk transport tankers. Copyright © 2012 Elsevier B.V. All rights reserved.

Full Text Available Using the theory of social fields by P. Bourdieu the article describes the features of the advertising as a symbolic cultural field functioning. Confined to the locality of its actions, advertising creates cultural forms, images, facilities, value­based judgments that become widespread, claiming the role of human behavior that must be followed. The author defines advertising as a symbolic cultural field. To analyse the advertising field and determine the impact of advertising on learning and the formation of certain values and cultural patterns the author justifies application of critical discourse analysis (CDA. The meaning of notions «advertising discourse» and «discourses of advertising» are being exposed and delineated. The author propose and test research methodology of development and impact of advertising discourse on advertising consumers. The types of value discourses prevalent in the field of commercial advertising were identified. In the study, the author found that advertising discourses are dynamic entities that are changed according to time and the state of the society in which they operate. In particular, the discourses produced in advertising influences social context ­ developments in society, the dominant values and attitudes.

Full Text Available O artigo traça as diretrizes da política cultural implementada durante o segundo governo FHC: leis de incentivo fiscal, financiamento privado e regulação estatal. A ação cultural do governo atribuiu ao Estado o papel de intermediário no processo de financiamento, avalizando relações entre produtores culturais e agentes econômicos. Em lugar de um típico mecenato privado, instituiu-se uma nova modalidade de promoção cultural. A expansão das iniciativas nos diversos ramos da criação cultural não significou, necessariamente, a renovação das linguagens.This paper traces the guidelines of the cultural policies prevailing during Fernando Henrique Cardoso's second term of government: fiscal incentive legislation, private funding and state regulation. The government's cultural action designed the state as regulator, acting as "go-between" towards the cultural producers and the new economic agents. Instead of a typical private patronage model, the state instituted a new kind of cultural promotion. The expansion of initiatives in every domain of cultural creation did not mean, necessarily, the renewal of languages.

Full Text Available In this paper the relevance of understanding the different meanings of culture in the counseling profession is presented. Two approaches to the concept of culture as they relate to counseling are suggested: the first approach stresses the organisational culture of the institution where the counselor works; the second —the multicultural approach— calls for the complex recognition of the variety of ethnic cultural backgrounds of those involved in the counseling situation. Professional practices are analysed as means for the reinforcement of present conditions or as ways for changing them. The concepts of empowerment of and advocacy for our clients are put forward as main components in the challenging new roles of the counseling profession. Implications for counselors are suggested.

Culture of periprosthetic tissue specimens in blood culture bottles is more sensitive than conventional techniques, but the impact on laboratory workflow has yet to be addressed. Herein, we examined the impact of culture of periprosthetic tissues in blood culture bottles on laboratory workflow and cost. The workflow was process mapped, decision tree models were constructed using probabilities of positive and negative cultures drawn from our published study (T. N. Peel, B. L. Dylla, J. G. Hughes, D. T. Lynch, K. E. Greenwood-Quaintance, A. C. Cheng, J. N. Mandrekar, and R.

Sensitivity analysis was performed using various rates of positive cultures. Annualized labor savings were estimated based on salary costs from the U.S. Labor Bureau for Laboratory staff. The model demonstrated a 60.1% reduction in mean total staff time with the adoption of tissue inoculation into blood culture bottles compared to conventional techniques (mean ± standard deviation, 30.7 ± 27.6 versus 77.0 ± 35.3 h per month, respectively; P < 0.001). The estimated annualized labor cost savings of culture using blood culture bottles was $10,876.83 (±$337.16). Sensitivity analysis was performed using various rates of culture positivity (5 to 50%). Culture in blood culture bottles was cost-effective, based on the estimated labor cost savings of $2,132.71 for each percent increase in test accuracy. In conclusion, culture of periprosthetic tissue in blood culture bottles is not only more accurate than but is also cost-saving compared to conventional culture methods.

2010-03-01

Full Text Available The article focuses on intertextuality as a concept associated with the tradition of postmodernism textology and a phenomenon of text interaction with the semiotic cultural environment. The concept of intertextuality emerges as an essential condition for the construction of meaning which includes the dialogical characteristics of the polylogue culture field. The author examines the evolution of intertextuality since M.M. Bakhtin up to contemporary theoreticians of postmodernism. The concept of intertextuality is the prominent characteristics of the contemporary «post» culture and the major channel of inter-cultural diffusion.

The SERI Microalgae Culture Collection provides a repository for strains identified or developed for mass culture biomass production and makes these strains readily available to the research community. The strains in the collection have been selected for their potential in biomass fuel applications, and many produce significant quantities of cellular storage lipids. All of the newly added strains have been recently isolated by SERI and its subcontractors in organized screening programs. Many have been tested in outdoor mass culture systems, and several have demonstrated excellent performance as biomass producers. The strains added to the collection this year have been isolated from inland saline waters and marine waters. We believe that the strains in this collection can provide a source of extremely useful organisms, both for laboratory experimentation and for mass culture research. Most of the strains are currently nonaxenic. Again this year, cultures will be shipped free of charge to interested researchers. An important function of the culture collection catalog, in addition to listing the available strains, is to provide culture and performance data for each of the organisms. By collecting a summary of the requirements and characteristics of these organisms, we hope to allow requestors of cultures to begin productive research with a minimum of preliminary work on culture techniques.

DDT (1,1,1-trichloro-2,2- bis (4-chlorophenyl) ethane) is one of the organic synthetic pesticides that has many negative effects for human health and the environment. The purpose of this study was to investigate the synergistic effect of mixed cutures of white-rot fungus, Pleurotus ostreatus , and biosurfactant-producing bacteria, Pseudomonas aeruginosa and Bacillus subtilis , on DDT biodegradation. Bacteria were added into the P. ostreatus culture (mycelial wet weight on average by 8.53 g) in concentrations of 1, 3, 5, and 10 ml (1 ml ≈ 1.25 × 10 9 bacteria cells/ml culture). DDT was degraded to approximately 19% by P. ostreatus during the 7-day incubation period. The principal result of this study was that the addition of 3 ml of P. aeruginosa into P. ostreatus culture gave the highest DDT degradation rate (approximately 86%) during the 7-day incubation period. This mixed culture combination of the fungus and bacteria also gave the best ratio of optimization of 1.91. DDD (1,1-dichloro-2,2- bis (4-chlorophenyl) ethane), DDE (1,1-dichloro-2,2- bis (4-chlorophenyl) ethylene), and DDMU (1-chloro-2,2- bis (4-chlorophenyl) ethylene) were detected as metabolic products from the DDT degradation by P. ostreatus and P. aeruginosa . The results of this study indicate that P. aeruginosa has a synergistic relationship with P. ostreatus and can be used to optimize the degradation of DDT by P. ostreatus .

What Is so "Cultural" About Cultural Entrepreneurship

Directory of Open Access Journals (Sweden)

Staffan Albinsson

2017-04-01

Full Text Available The term “cultural entrepreneurship” has been increasingly used during the new millennium, mirroring the rapidly growing importance of the “quaternary sector of the economy,” i.e. knowledge-based industries, including culture. Exploration of the literature in which the term “cultural entrepreneurship” is used does not bring a solid, clear-cut, and unambiguous understanding of its definition or meaning. The aim of this paper is to present various uses of the concept and to bring about some clarity in how the concept can be understood. Two overarching uses of the cultural entrepreneurship concept have been found: 1. the anthropologist’s and institutional economist’s use, which indicates the dynamic development of intangible cultural features such as symbols, myths, languages, beliefs, values, norms, rituals, and attitudes in and between societies, and 2. the arts development use, which indicates the dynamic development of cultural services, tangible goods, and individual or collective career promotion. Most authors use a cultural entrepreneurship concept without defining it. Authors could apply more precise definitions by using a quadruple bottom-line framework to position themselves in the nexus of financial, social, artistic, and cultural perspectives.

Therapeutic potential of secondary metabolites produced in the hairy roots cultures

Tomasz Kowalczyk

2015-05-01

Full Text Available Plants have always been a source of many valuable substances for humans. Growing advancement of methods of modern biotechnology, combined with genetic engineering techniques, gradually increase the variety of compounds obtained, the number of plant species used and the production efficiency. Consequently, there is an undebatable interest in biotechnological production of such compounds, especially those pharmacologically active, that can be used in treatment of neoplastic, viral, and many other types of diseases. Most of these compounds represent a diverse group of secondary metabolites. One of the effective ways of obtaining such molecules is the utilization of hairy roots cultures. The advantages of such systems make them an attractive method of obtaining important plant-derived compounds, creating an interesting alternative to other methods, including the cell suspension cultures or expensive chemical syntheses.

The conducting shell stellarator: A simple means for producing complicated fields

International Nuclear Information System (INIS)

Sheffield, G.V.

1997-01-01

One of the main characteristics of stellarators, both helical and modular, is that their coil sets must take difficult shapes in order to produce the complicated stellarator magnetic fields. The complex coil shapes make fabrication difficult and costly compared to say the toroidal field, TF, coil set of a tokamak. The conducting shell stellarator, CSS, configuration described in this report shows that complicated stellarator fields can be produced by inducing eddy currents in a conducting shell from a simple TF coil set (a field that varies like 1/R). This technique is applicable not only to a pulsed system at room or cryogenic temperatures, but can be implemented for a superconducting TF with a superconducting shell in a stellarator reactor. The CSS has the added benefit that within this device the metallic shell which can be made up of discrete plates can be changed out and replaced with new plates to create a different stellarator configuration within the same TF coil set. The work of creating the complicated magnetics is done by the passive conductor reshaping the simple TF field

Ethnographic exercises as activities in public space: Social Occupational Therapy in art, culture and politics

Full Text Available Ethnographic exercises are discussed - as proposed by the Metuia Project/ USP between 2007 and 2013 - as an activity able to enhance the recognition of the compound, plural and sometimes contradictory knowledge, but produced creatively in the intellectual and social do, in the interaction among students, occupational therapists, researchers and homeless people. It starts from the need to develop an understanding of the significant activities of artists working in the public spaces in São Paulo, as it persists as a plurality of meanings that the street acquires amid disputes of interests and cultural tensions, but also interconnections and creativity. The itinerant life and social areas’ characteristics, combined with reflections of urban anthropology and ethnographic research favored the theoretical and practical teaching in dialogic territorial shares of social occupational therapy. This article is the result of reflections built from the research Circuits and religious practices in life trajectories of adult homeless people in city of São Paulo, associated with university extension project linked to Metuia Project/USP, called Point meeting and culture: social networks, culture and social occupational therapy. In conclusion, on the one hand, there is need for renewed reflection about the occupational therapist’s place, considering the asymmetries of the relations in the construction of knowledge. On the other hand, it indicates that the produced activities, necessarily, in dialogical relations, only share meanings when inserted into the experience of the difference in consistent proposals with its own plasticity and in the middle of specific social and cultural contexts.

Extended-spectrum beta-lactamase-producing bacteria are not detected in supragingival plaque samples from human fecal carriers of ESBL-producing Enterobacteriaceae

2014-08-01

Full Text Available Background: The prevalence of infections caused by Cefotaximase-Munich (CTX-M-type extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-E has rapidly increased during the past 15 years. Enterobacteriaceae are commonly found in the gastrointestinal tract and long-term intestinal carriage is considered important for the spread of ESBL and as a source of clinical infections. Oral biofilm such as supragingival plaque is known to contain numerous antibiotic resistance determinants and may also represent a poorly investigated site for ESBL carriage and further spread. Objective: To investigate possible carriage of ESBL-producing bacteria in supragingival plaque of known fecal carriers of these bacteria. Design: We screened for the presence of aerobic and anaerobic ESBL-producing bacteria and blaCTX-M in supragingival plaque samples from healthy human adults with culture-verified fecal carriage of CTX-M-producing Escherichia coli. The presence or absence of Enterobacteriaceae and ESBL-producing bacteria in plaque samples was evaluated using culture-based methods and consensus CTX-M PCR. Results: Oral samples were obtained from 17 participants with known previous carriage of ESBL-producing E. coli. No ESBL-producing bacteria or ESBL genes were detected using culture-based and molecular methods. One colony of Rahnella aquatilis harboring the class A ESBL gene bla RAHN-1/2 was identified in an oral sample from one of the participants. Conclusion: This pilot study supports the notion that the presence of CTX-M-producing bacteria is uncommon in oral plaque of healthy human adult fecal carriers. Due to the limited number of persons tested, a low prevalence of oral ESBL-carriage in healthy adults or carriage in selected groups of patients cannot be excluded. To our knowledge, this is the first description of an R. aquatilis with the RAHN-1/2 gene in the oral cavity.

Influence of culture medium supplementation of tobacco NT1 cell suspension cultures on the N-glycosylation of human secreted alkaline phosphatase.

We report for the first time that culture conditions, specifically culture medium supplementation with nucleotide-sugar precursors, can alter significantly the N-linked glycosylation of a recombinant protein in plant cell culture. Human secreted alkaline phosphatase produced in tobacco NT1 cell suspension cultures was used as a model system. Plant cell cultures were supplemented with ammonia (30 mM), galactose (1 mM) and glucosamine (10 mM) to improve the extent of N-linked glycosylation. The highest levels of cell density and active extracellular SEAP in supplemented cultures were on average 260 g/L and 0.21 U/mL, respectively, compared to 340 g/L and 0.4 U/mL in unsupplemented cultures. The glycosylation profile of SEAP produced in supplemented cultures was determined via electrospray ionization mass spectrometry with precursor ion scanning and compared to that of SEAP produced in unsupplemented cultures. In supplemented and unsupplemented cultures, two biantennary complex-type structures terminated with one or two N-acetylglucosamines and one paucimannosidic glycan structure comprised about 85% of the SEAP glycan pool. These three structures contained plant-specific xylose and fucose residues and their relative abundances were affected by each supplement. High mannose structures (6-9 mannose residues) accounted for the remaining 15% glycans in all cases. The highest proportion (approximately 66%) of a single complex-type biantennary glycan structure terminated in both antennae by N- acetylglucosamine was obtained with glucosamine supplementation versus only 6% in unsupplemented medium. This structure is amenable for in vitro modification to yield a more human-like glycan and could serve as a route to plant cell culture produced therapeutic glycoproteins.

Full Text Available PURPOSE: Transplantation of pancreatic islets to Type 1 diabetes patients is hampered by inflammatory reactions at the transplantation site leading to dysfunction and death of insulin producing beta-cells. Recently we have shown that co-transplantation of neural crest stem cells (NCSCs together with the islet cells improves transplantation outcome. The aim of the present investigation was to describe in vitro interactions between NCSCs and insulin producing beta-TC6 cells that may mediate protection against cytokine-induced beta-cell death. PROCEDURES: Beta-TC6 and NCSC cells were cultured either alone or together, and either with or without cell culture inserts. The cultures were then exposed to the pro-inflammatory cytokines IL-1β and IFN-γ for 48 hours followed by analysis of cell death rates (flow cytometry, nitrite production (Griess reagent, protein localization (immunofluorescence and protein phosphorylation (flow cytometry. RESULTS: We observed that beta-TC6 cells co-cultured with NCSCs were protected against cytokine-induced cell death, but not when separated by cell culture inserts. This occurred in parallel with (i augmented production of nitrite from beta-TC6 cells, indicating that increased cell survival allows a sustained production of nitric oxide; (ii NCSC-derived laminin production; (iii decreased phospho-FAK staining in beta-TC6 cell focal adhesions, and (iv decreased beta-TC6 cell phosphorylation of ERK(T202/Y204, FAK(Y397 and FAK(Y576. Furthermore, co-culture also resulted in cadherin and beta-catenin accumulations at the NCSC/beta-TC6 cell junctions. Finally, the gap junction inhibitor carbenoxolone did not affect cytokine-induced beta-cell death during co-culture with NCSCs. CONCLUSION: In summary, direct contacts, but not soluble factors, promote improved beta-TC6 viability when co-cultured with NCSCs. We hypothesize that cadherin junctions between NCSC and beta-TC6 cells promote powerful signals that maintain beta

Re-interpreting cultural values: Tajikistani students abroad

Full Text Available This article looks at the mobility of Tajikistani students and how they negotiate their place in an increasing globalised world, where national boundaries are becoming more navigable. It explores how structural and cultural factors intersect and influence young people’s choices as they re-shape their connections to their homeland, and re-negotiate cultural meanings in the new geographical and cultural contexts they find themselves in. This inquiry uses the concept of translocality which frames the negotiation of cultural meanings in a distant geographical and (host cultural space by acknowledging the place of the “local connection” within international mobility. It does this by examining students’ perceptions of two cultural concepts: nomus or “keeping the family name high in the community” and kase shudan or “being the shaper of one’s own destiny.” Drawing on Stephen and Storey’s conceptualisation of culture (and the local notions of agency the article explores how continuity and contestation are juxtaposed and brought to bear on the new meaning-making by the students, against the national and international agendas that define student mobility choices. Using qualitative methodology, the researchers engaged with Tajikistani research participants in England and Japan, and looked at what those decisions about mobility mean for the individual students, locating them in a translocal (as opposed to a transnational space. The article finds that contrary to the usual expectations of immigrants adhering more closely to cultural values (for fear of diluting them in a new setting, while the local cultures keep evolving, these students re-interpreted traditional values to take account of their new settings and their exposure to new cultures and spaces and sought to expand meanings rather than constrain them in traditional moulds.

Fast growing aspens in the development of a plant micropropagation system based on plant-produced ethylene action

2013-01-01

Representatives of the genus Populus (poplars), such as Populus tremula L. (European aspen) and its fast-growing hybrids, are recognized as being among the most suitable tree species for short rotation coppicing in Northern Europe. Several technologies have been developed for fast propagation of selected aspen genotypes, including laboratory (in vitro) micropropagation, which is usually based on the action of exogenous plant hormones. Seeking to minimize the use of the latter, the present study was designed to test if the conditions suitable for increased accumulation of plant-produced gas, including the gaseous plant hormone ethylene, inside a culture vessel could contribute to commercially desirable changes in aspen development. Shoot cultures of several European and hybrid (Populus tremuloides Michx. × P. tremula) aspen genotypes were studied using two different types of culture vessels: tightly sealed Petri dishes (15 × 54 mm) designed to provide restricted gas exchange (RGE) conditions, and capped (but not sealed) test tubes (150 × 18 mm) providing control conditions. Under RGE conditions, not only the positive impact of the ethylene precursors 1-aminocyclopropane-1-carboxylic-acid (ACC) and ethephon on shoot proliferation was demonstrated but also a several-fold increase, compared to the control conditions, in the mean shoot number per explant was recorded even on the hormone-free nutrient medium. Moreover, the shoots developed under RGE conditions were distinguished by superior rooting ability in the subsequent culture. These results suggest that a plant micropropagation system based on the action of plant-produced ethylene rather than of exogenous hormones is possible. -- Highlights: ► Aspen in vitro cultures were grown in different vessels. ► Small-volume vessels were used for restriction of gas exchange. ► Aspen explants produced most shoots in small-volume vessels. ► Shoot proliferation was increased due to explant response to ethylene. �

The value of cultures to modern microbiology.

Science.gov (United States)

Austin, Brian

2017-10-01

Since the late nineteenth century, pure cultures have been regarded as the cornerstone of bacteriology. However, not all bacteria will multiply sufficiently to produce visible colonies on solid media; some cells will produce micro-colonies that are invisible to the naked eye. Moreover, the proportion of culturable cells that produce visible growth will vary according to the species and the state of the cells-are they actively growing or comparatively inactive? The latter have a poorer rate of recovery in terms of cultivability. It is unclear whether or not an individual colony is always derived from a single cell; it is possible that organisms in close proximity to each other may multiply and come together to produce single colonies. Then, the resultant growth will most certainly be derived from more than one initial cell. Although it is generally assumed that streaking and re-streaking on fresh media will purify any culture, there is evidence for microbial consortia interacting to form what appear to be single pure cultures. As so-called pure cultures underpin traditional microbiology, it is relevant to understand that the culture does not necessarily contain clones of identical bacteria, but that there may be variation in the genetic potential of the component cells, i.e. the cells are not homogeneous. Certainly, many bacteria change rapidly upon culturing, with some becoming bigger and less active. It is difficult to be sure if these changes reflect a loss or change of DNA or whether standard culturing methods select faster growing cells that are effectively not representative of the environment from which they were derived. These concepts are reviewed with an emphasis on bacterial fish pathogens.

Benner's remnants: culture, tradition and everyday understanding.

Science.gov (United States)

Paley, John

2002-06-01

Benner's account of meaning and embodiment in nursing depends on a theory which she has never fully articulated, although she makes numerous allusions to it. Behind the background of shared meanings hovers something called 'culture', which provides each individual with meaning, determines what counts as real for her, and actively hands down interpretation-laden practices. This view is based, Benner claims, on the Heideggerian assumption that the meaning and organization of a culture precedes individual meaning-giving activity. I explore Benner's implicit view of culture, drawing on her published work over 15 years, and offer an appraisal of it. In doing so, I attempt to make sense of some rather strange remarks Benner has recently made about 'remnants' of Cartesian and Kantian thinking being found in the everyday understandings of people with asthma. The concept of culture is developed with reference to both Benner's own work and that of the anthropologist, Clifford Geertz, whose work she frequently cites. Having identified the principal tenets of what we might conveniently call the Benner-Geertz theory, I proceed to interrogate the theory, using the recent anthropological literature -- and, in particular, materialist attacks on the idea of culture as a system of meanings -- in order to cast doubt on it. I also review, very briefly, an alternative way of understanding 'culture', which is not vulnerable to the same criticisms. Benner's implicit theory of culture is revealed, somewhat ironically, as an inverted form of Cartesian dualism. Its intellectual provenance is not Heidegger, who appears to reject it, but the sort of American sociology associated with Talcott Parsons. As a corollary, it is suggested that Benner's 'remnants' analogy cannot be justified, and that the idea of Cartesian and Kantian concepts permeating Western culture, infecting both the providers and receivers of health care, is a myth.

Full Text Available Cultural phenomena and processes in the contemporary society, influenced by the social development models and by the fact that the constitutive elements of the culture have become the decisive factors of social change, are the determinants of the cultural policies. They are centered on the active process of cultural globalization that emphasizes besides the assimilation of the European principles, also the preservation of the cultural dialog without identity loss. Contemporary culture cannot be appreciated unless we know the main processes and phenomena that lately have generated impressive changes in the area of technology and means of communication. Due to these transformations we witness a change of the cultural paradigms, a mutation of values.

2008-09-01

Trait and cultural psychology perspectives on cross-role consistency and its relation to adjustment were examined in 2 individualistic cultures, the United States (N=231) and Australia (N=195), and 4 collectivistic cultures, Mexico (N=199), the Philippines (N=195), Malaysia (N=217), and Japan (N=180). Cross-role consistency in trait ratings was evident in all cultures, supporting trait perspectives. Cultural comparisons of mean consistency provided support for cultural psychology perspectives as applied to East Asian cultures (i.e., Japan) but not collectivistic cultures more generally. Some but not all of the hypothesized predictors of consistency were supported across cultures. Cross-role consistency predicted aspects of adjustment in all cultures, but prediction was most reliable in the U.S. sample and weakest in the Japanese sample. Alternative constructs proposed by cultural psychologists--personality coherence, social appraisal, and relationship harmony--predicted adjustment in all cultures but were not, as hypothesized, better predictors of adjustment in collectivistic cultures than in individualistic cultures.

Full Text Available The background of this problem is the increasing number of Indonesian citizens who perform mixed marriages, especially women who are married to foreign nationals. This, resulted in the problem starts from differences of religion or belief, culture and lifestyle are different. The purpose of this study is to find and explain the motives, meaning and experience of Indonesian Muslim women as perpetrators of intermarriage. This research method using the phenomenological method that focuses on the study of meaning in everyday life from the perspective of those who experience it. Data collection techniques used participant observation, interview and documentation study. Subjects were Indonesian Muslim women aged 30-40 years, were married to foreign nationals by purposive sampling technique. The results showed that mixed marriages have a motive "because" that is the motive trauma and interest, while the motive "for" consists of the dream motive, worship and repair descent. Likewise intermarriage experience demonstrated mutual culturally adjust, adapt to a multicultural, open and romantic attitude. While the meaning of marriage is an interesting mix, happy, merging two cultures, respect for differences, mutual understanding, complex, beautiful. Construction of meaning formed that a mixed marriage is a marriage of attractive, beautiful, full of challenges in the face of differences in terms of culture, habits and mindset in running family life.

Caution is urged in the use of freshly isolated cultures of human diploid fibroblasts for quantitative studies of radiosensitivity. The distribution of x ray sensitivities of 'normal' human fibroblast cultures of foetal origin (10 subjects, skin or lung biopsy) and post-foetal origin (34 subjects, skin biopsy) are compared with the distribution in 12 patients with ataxia telangiectasia (probability of including any one of these in a normal post-foetal distribution is 0.01%). Cultures from nominally normal subjects showed a broad distribution of D 0 range of 98 +- 160 rad and assuming normal distribution, a mean +- one standard deviation of 122 +- 17 rad. Mean D 0 values for foetal origin cultures were 117 +- 12; values for post-foetal cultures D 0 were 124 +- 18. No systematic variation in D 0 was observed for age of donor, number of cell divisions in culture or for cloning efficiency. For ataxia telangiectasia D 0 values were 46 +- 7 rad. (U.K.)

Aseptic model minces were inoculated with commercial samples of either Staphylococcus xylosus or Staphylococcus carnosus. Volatiles produced by the cultures were collected during growth by diffusive sampling onto adsorbent traps, identified by thermal desorption-gas chromatography-mass spectrometry...... and quantified by thermal desorption-gas chromatography-flame ionisation. The data were analysed by principal component analysis. The study showed that both starter cultures produced a large number of volatiles in concentrations of sensory importance. Almost all of the major volatiles resulted from amino acid...... degradation, suggesting that the effect of Staphylococcus starter cultures on flavour quality is much related to their ability of catabolizing amino acids. With the exception of diacetyl, acetoin and 2-methyl-1-butanol, both cultures formed the same volatiles. Diacetyl and acetoin were not produced...

Not saying I am happy does not mean I am not: cultural influences on responses to positive affect items in the CES-D.

Given the emphasis on modesty and self-effacement in Asian societies, the present study explored differential item responses for 2 positive affect items (5 = Hopeful and 8 = Happy) on a short form of the Center for Epidemiologic Studies-Depression scale. The samples consisted of elderly non-Hispanic Whites (n = 450), Korean Americans (n = 519), and Koreans (n = 2,030). Multiple Indicator Multiple Cause models were estimated to identify the impact of group membership on responses to the positive affect items while controlling for the latent trait of depressive symptoms. The data revealed that Koreans and Korean Americans were less likely than non-Hispanic Whites to endorse the positive affect items. Compared with Korean Americans who were more acculturated to mainstream American culture, those who were less acculturated were less likely to endorse the positive affect items. Our findings support the notion that the way in which people endorse depressive symptoms is substantially influenced by cultural orientation. These findings call into question the common use of simple mean comparisons and a universal cutoff point across diverse cultural groups.

Nanostructured (porous) silicon is a promising biodegradable biomaterial, which is being intensively researched as a tissue engineering scaffold and drug-delivery vehicle. Here, we tested the biocompatibility of non-treated and thermally-oxidized porous silicon particles using an indirect cell viability assay. Initial direct cell culture on porous silicon determined that human lens epithelial cells only poorly adhered to non-treated porous silicon. Using an indirect cell culture assay, we found that non-treated microparticles caused complete cell death, indicating that these particles generated a toxic product in cell culture medium. In contrast, thermally-oxidized microparticles did not reduce cell viability significantly. We found evidence for the generation of reactive oxygen species (ROS) by means of the fluorescent probe 2',7'-dichlorofluorescin. Our results suggest that non-treated porous silicon microparticles produced ROS, which interacted with the components of the cell culture medium, leading to the formation of cytotoxic species. Oxidation of porous silicon microparticles not only mitigated, but also abolished the toxic effects.

Yugoslav Naive Art and Popular Culture

Meta Kordiš

After the Second World War, the Yugoslav socialist state also strove to equalize and democratize society through art by minimizing the differences between the producers and consumers of art. Such a policy led to the decentralization of culture by forming various cultural and artistic institutions and by holding cultural events and spectacles in the countryside and peripheral areas. Through these various informal ideological mechanisms, the state apparatus exercised its authority in socializing its people in the spirit of Yugoslav socialist self-management and the ideology of brotherhood and unity by joining together the producers and consumers of naive art from various ethnicities, cultures, and social classes. Unfortunately this transformed naive art at its peak of popularity into a decorative and souvenir artifact with a pastoral image and folklore motifs. The encouragement from the authorities on the one hand and the market on the other produced and reproduced simple art forms and narrative contents without a complex iconography, which were consumed uncritically and on a large scale. Consequently, this completely denied the core of naive art and resulted in its final devaluation.

Within- and between-culture variation: individual differences and the cultural logics of honor, face, and dignity cultures.

Leung, Angela K-Y; Cohen, Dov

The CuPS (Culture × Person × Situation) approach attempts to jointly consider culture and individual differences, without treating either as noise and without reducing one to the other. Culture is important because it helps define psychological situations and create meaningful clusters of behavior according to particular logics. Individual differences are important because individuals vary in the extent to which they endorse or reject a culture's ideals. Further, because different cultures are organized by different logics, individual differences mean something different in each. Central to these studies are concepts of honor-related violence and individual worth as being inalienable versus socially conferred. We illustrate our argument with 2 experiments involving participants from honor, face, and dignity cultures. The studies showed that the same "type" of person who was most helpful, honest, and likely to behave with integrity in one culture was the "type" of person least likely to do so in another culture. We discuss how CuPS can provide a rudimentary but integrated approach to understanding both within- and between-culture variation. (c) 2011 APA, all rights reserved

1984-01-01

The nature of hematopoietic regulatory factors elaborated by the adherent (stromal) cells of long-term murine bone marrow cultures and the effect of in vitro stromal irradiation (XRT) on the production of these factors was investigated. Using an in situ stromal assay it was possible to demonstrate stromal elaboration of at least two colony-stimulating activities, ie, granulocyte/macrophage colony-stimulating activity (G/M-CSA) and megakaryocyte colony-stimulating activity (Meg-CSA). Exposure of the stroma to XRT resulted in dose-dependent elevations of both activities that correlated inversely with total myeloid cell mass. Mixture experiments that combined control and irradiated stroma revealed that the hematopoietically active control stroma could block detection of XRT-related G/M-CSA elevations. Antiserum directed against purified L cell colony-stimulating factor (CSF) reduced granulocyte/macrophage colony formation in the target layer but did not effect the increased Meg-CSA. While a radioimmunoassay for L-cell type CSF was unable to detect significant differences in concentrated media from control and irradiated cultures, bioassays of these media revealed XRT-related G/M-CSA elevations. These results indicate that the G/M-CSA elaborated in these cultures is immunologically distinct from the Meg-CSA produced, and although distinct from L cell CSF, the G/M-CSA is crossreactive with the L cell CSF antiserum. Morphologic, histochemical, and factor VII antigen immunofluorescent studies were performed on the stromal cell population responsible for production of these stimulatory activities. In addition to ''fat'' cells, the stromal cells remaining after XRT were composed of two predominant cell populations. These included a major population of acid phosphatase and nonspecific esterase-positive macrophage-like cells and a minor population of factor VII antigen negative epithelioid cells

Exogenous cellulases of thermophilic micromycetes. Pt. 1. Selection of producers

1986-01-01

More than 600 micromycetes - representatives of different genera have been investigated for their ability to produce exogenous cellulases. Most of the investigated cultures were found to produce these enzymes, 24 cultures being thermophilic, and 18 thermotolerant. Cellulase or its derivatives proved to be the most favourable carbon source for cellulase secretion. None of the thermophilic cultures studied manifested the ability of exogenous exoglucanase biosynthesis. Using UV-rays as mutagen, a mutant strain A. terreus T-49 has been obtained being characterized by an increased endo-glucanase and cellobiase activity, as compared to the initial strains. The cellulase preparations of thermophilic micromycetes contain one cellulasic component: endo-glucanase, or two: endo-glucanase and cellobiase.

2014-01-01

It is widely believed that certain emotions are universally recognized in facial expressions. Recent evidence indicates that Western perceptions (e.g., scowls as anger) depend on cues to US emotion concepts embedded in experiments. Since such cues are standard feature in methods used in cross-cultural experiments, we hypothesized that evidence of universality depends on this conceptual context. In our study, participants from the US and the Himba ethnic group sorted images of posed facial expressions into piles by emotion type. Without cues to emotion concepts, Himba participants did not show the presumed “universal” pattern, whereas US participants produced a pattern with presumed universal features. With cues to emotion concepts, participants in both cultures produced sorts that were closer to the presumed “universal” pattern, although substantial cultural variation persisted. Our findings indicate that perceptions of emotion are not universal, but depend on cultural and conceptual contexts. PMID:24708506

Cultural Sensitiveness of School Goals and Students’ Failure in Turkey

Full Text Available Education is the means by which society provides for the transmission or advancement of its culture and it is formally done at schools that are the arena of human interaction aimed at producing learning. But some people in that interaction aimed at producing learning cannot achieve as much as the others due to some social or individual factors especially when the society is not homogeneous in terms of culture, language, etc.All cultures do not require the same kinds of knowledge and all may have distinct goals and expectations in education. This study aims at presenting the consensus and conflict in perspectives of students of different ethnic origins on general goals of education and expectations from schools in East and Southeast Turkey. The results will be used to generate a rationale to assume that the failure of students in East and Southeast Turkey where majority of population is ethnically diverse, may be because of the lack of divergent goals and expectations set for school curriculum or that the failure of students is dependent on some other factors except the unique school curriculum unresponsive to cultural or ethnic diversity. For this purpose, the goals of general education (1973, Law number 1739, Item number 2, and school expectations developed by House (1973 were prepared as questionnaire items, piloted, validated and administered to 9373 secondary school students in east and southeast Turkey. The findings of this study were that the students of different ethnic origins value the goals and expectations set for school curriculum in Turkey in significantly different ways.

Translation Strategy of Chinese Culture-loaded Lexes and the Dissemina-tion of Chinese Culture

Institute of Scientific and Technical Information of China (English)

WU Li-li

2016-01-01

Lexes are the most important and basic element of a language. Chinese culture-loaded lexes are those words or expres-sions that are greatly rich in Chinese culture. They can reflect the characteristics of Chinese culture and Chinese nation. There-fore, it is of great significance to pay attention to the translation of Chinese culture-loaded lexes as they play a decisive role in disseminating Chinese culture. It can help promote Chinese culture worldwide, improve China’s cultural exchanges and commu-nication with other nations and strengthen China’s status in the world. This paper focuses on the Chinese culture-loaded words and proposes some possible means of translation with the purpose of spreading Chinese culture.

High cell density cultures produced by internal retention: application in continuous ethanol fermentation

Directory of Open Access Journals (Sweden)

Berta Carola Pérez

2004-07-01

Full Text Available Ethanol has provoked great interest due to its potential as an alternative fuel. Nevertheless, fermentation processes must be developed by increasing the low volumetric productivity achieved in conventional cultures (batch or continuous to make this product become economically competitive. This can be achieved by using techniques leading to high cell concentration and reducing inhibition by the end-product. One of the frequently employed methods involves cell recycling. This work thus developed a membrane reactor incorporating a filtration module with 5 u,m stainless steel tubular units inside a 3L stirred jar fermenter for investigating its application in continuous ethanol production. The effects of cell concentration and transmembrane pressure difference on permeate flux were evaluated for testing the filtration module's performance. The internal cell retention system was operated in Saccharomyces cerevisiae continuous culture derived from sucrose, once fermentation conditions had been selected (30 °C, 1.25 -1.75 vvm, pH 4.5. Filter unit permeability was maintained by applying pulses of air. More than 97% of the grown cells were retained in the fermenter, reaching 51 g/L cell concentration and 8.51 g/L.h average ethanol productivity in culture with internal cell retention; this was twice that obtained in a conventional continuous culture. Key words: Membrane reactor, Saccharomyces cerevisiae, alcoholic fermentation, cell recycling.

A versatile, non genetically modified organism (GMO)-based strategy for controlling low-producer mutants in Bordetella pertussis cultures using antigenic modulation.

Science.gov (United States)

Goffin, Philippe; Slock, Thomas; Smessaert, Vincent; De Rop, Philippe; Dehottay, Philippe

2015-08-01

The uncontrolled presence of non-producer mutants negatively affects bioprocesses. In Bordetella pertussis cultures, avirulent mutants emerge spontaneously and accumulate. We characterized the dynamics of accumulation using high-throughput growth assays and competition experiments between virulent and avirulent (bvg(-) ) isolates. A fitness advantage of bvg(-) cells was identified as the main driver for bvg(-) accumulation under conditions of high virulence factor production. Conversely, under conditions that reduce their expression (antigenic modulation), bvg(-) takeover could be avoided. A control strategy was derived, which consists in applying modulating conditions whenever virulence factor production is not required. It has a wide range of applications, from routine laboratory operations to vaccine manufacturing, where pertussis toxin yields were increased 1.4-fold by performing early pre-culture steps in modulating conditions. Because it only requires subtle modifications of the culture medium and does not involve genetic modifications, this strategy is applicable to any B. pertussis isolate, and should facilitate regulatory acceptance of process changes for vaccine production. Strategies based on the same concept, could be derived for other industrially relevant micro-organisms. This study illustrates how a sound scientific understanding of physiological principles can be turned into a practical application for the bioprocess industry, in alignment with Quality by Design principles.

Persian Gardens: Meanings, Symbolism, and Design

Directory of Open Access Journals (Sweden)

Leila Mahmoudi Farahani

2016-01-01

Full Text Available Culture and identity in a society can be represented in the architecture and the meanings intertwined with it. In this sense, the architecture and design are the interface for transferring meaning and identity to the nation and future generations. Persian gardens have been evolved through the history of Persian Empire in regard to the culture and beliefs of the society. This paper aims to investigate the patterns of design and architecture in Persian gardens and the meanings intertwined with their patterns and significant elements such as water and trees. Persian gardens are not only about geometries and shapes; but also manifest different design elements, each representing a specific symbol and its significance among the society. This paper seeks to explore Persian gardens in terms of their geometric structure, irrigation system, network construction and pavilions alongside design qualities such as hierarchy, symmetry, centrality, rhythm and harmony. In the second stage, the paper investigates the fundamental symbols and their philosophy in the creation of Persian gardens and in relation to the architecture and design.

A monument to the player: preserving a landscape of socio-cultural capital in the transitional MMORPG

`Adrir'Scott, Michael

2012-12-01

Massively multiplayer online role-playing games (MMORPGs) produce dynamic socio-ludic worlds that nurture both culture and gameplay to shape experiences. Despite the persistent nature of these games, however, the virtual spaces that anchor these worlds may not always be able to exist in perpetuity. Encouraging a community to migrate from one space to another is a challenge now facing some game developers. This paper examines the case of Guild Wars® and its "Hall of Monuments", a feature that bridges the accomplishments of players from the current game to the forthcoming sequel. Two factor analyses describe the perspectives of 105 and 187 self-selected participants. The results reveal four factors affecting attitudes towards the feature, but they do not strongly correlate with existing motivational frameworks, and significant differences were found between different cultures within the game. This informs a discussion about the implications and facilitation of such transitions, investigating themes of capital, value perception and assumptive worlds. It is concluded that the way subcultures produce meaning needs to be considered when attempting to preserve the socio-cultural landscape.

Suspension cultures of Catharanthus roseus, Apocynum cannabinum and Conium maculatum were examined for their capacity to transform aniline, anisole, acetanilide, benzoic acid and coumarin. None of the cultures transformed acetanilide but each produced acetanilide when fed aniline. All three cultures converted benzoic acid to its para-hydroxy derivative. Coumarin was selectively hydroxylated at the 7-position by Catharanthus and Conium and anisole was O-demethylated only by older Catharanthus tissue.

Cultures of choice: towards a sociology of choice as a cultural phenomenon.

Science.gov (United States)

Schwarz, Ori

2017-09-07

The article explores different ways to conceptualize the relationship between choice and culture. These two notions are often constructed as opposites: while sociologies of modernization (such as Giddens') portray a shift from cultural traditions to culturally disembedded choice, dispositional sociologies (such as Bourdieu's) uncover cultural determination as the hidden truth behind apparent choice. However, choice may be real and cultural simultaneously. Culture moulds choice not only by inculcating dispositions or shaping repertoires of alternatives, but also by offering culturally specific choice practices, ways of choosing embedded in meaning, normativity, and materiality; and by shaping attributions of choice in everyday life. By bringing together insights from rival schools, I portray an outline for a comparative cultural sociology of choice, and demonstrate its purchase while discussing the digitalization of choice; and cultural logics that shape choice attribution in ways opposing neoliberal trends. © London School of Economics and Political Science 2017.

We first review research on culture effects in teams, illustrating that mean levels of team cultural values have main (i.e. direct) effects, indirect effects (i.e. mediated by intervening variables), and moderating influences on team processes and outcomes. Variance in team cultural values or on country of origin (i.e. nationality diversity) also has main effects on team functioning, and we highlight contextual variables that strengthen or weaken these main effects. We next review research examining the effect of variance in team cultural values on global virtual teams, specifically. Finally, we review research on how cultural values shape employees' receptivity to empowering leadership behavior in teams. We conclude by discussing critical areas for future research.

Keeping patients safe in healthcare organizations: a structuration theory of safety culture.

Science.gov (United States)

Groves, Patricia S; Meisenbach, Rebecca J; Scott-Cawiezell, Jill

2011-08-01

This paper presents a discussion of the use of structuration theory to facilitate understanding and improvement of safety culture in healthcare organizations. Patient safety in healthcare organizations is an important problem worldwide. Safety culture has been proposed as a means to keep patients safe. However, lack of appropriate theory limits understanding and improvement of safety culture. The proposed structuration theory of safety culture was based on a critique of available English-language literature, resulting in literature published from 1983 to mid-2009. CINAHL, Communication and Mass Media Complete, ABI/Inform and Google Scholar databases were searched using the following terms: nursing, safety, organizational culture and safety culture. When viewed through the lens of structuration theory, safety culture is a system involving both individual actions and organizational structures. Healthcare organization members, particularly nurses, share these values through communication and enact them in practice, (re)producing an organizational safety culture system that reciprocally constrains and enables the actions of the members in terms of patient safety. This structurational viewpoint illuminates multiple opportunities for safety culture improvement. Nurse leaders should be cognizant of competing value-based culture systems in the organization and attend to nursing agency and all forms of communication when attempting to create or strengthen a safety culture. Applying structuration theory to the concept of safety culture reveals a dynamic system of individual action and organizational structure constraining and enabling safety practice. Nurses are central to the (re)production of this safety culture system. © 2011 Blackwell Publishing Ltd.

Playing up and playing down cultural identity: Introducing cultural influence and cultural variability.

Science.gov (United States)

Ferguson, Gail M; Nguyen, Jacqueline; Iturbide, Maria I

2017-01-01

Cultural variability (CV) is introduced as an overlooked dimension of cultural identity development pertaining to emphasizing and de-emphasizing the influence of a single cultural identity (i.e., cultural influence [CI]) on daily interactions and behaviors. The Cultural IDentity Influence Measure (CIDIM) is introduced as a novel measure of CI and CV, and hypothesis-driven validation is conducted in two samples along with exploration of associations between CV and well-being. A multicultural sample of 242 emerging adults participated in a daily diary study (Mage = 19.95 years, SDage = 1.40) by completing up to eight daily online surveys containing the CIDIM, criterion measures (ethnic identity, other group orientation, ethnic identity salience and daily variability in salience, social desirability), and measures of personal and interpersonal well-being. A second validation sample (n = 245) completed a 1-time survey with the CIDIM and a subset of criterion measures. Results using both samples show evidence of CI and CV and demonstrate the validity, reliability, and domain-sensitivity of the CIDIM. Further, CV made unique and positive contributions to predicting interaction quality after accounting for ethnic salience and variability in ethnic salience. An analytic approach utilizing standard deviations produced near-identical results to multilevel modeling and is recommended for parsimony. Ethnic minority and majority individuals make daily adjustments to play up and play down the influence of cultural identity on their social interactions and behaviors, and these adjustments predict interpersonal well-being. Cultural influence and cultural variability contribute to our emerging understanding of cultural identity as dynamic and agentic. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

LYOPHILIZATION EFFECT ON PRODUCTIVITY OF BUTANOL-PRODUCING STRAINS

2016-10-01

Full Text Available Investigation of lyophilization effect on the productivity of butanol-producing strains was the aim of our research. For this purpose we used butanol-producing strains; technical glycerol; biomass of switchgrass Panicum virgatum L. Lyophilization was performed using a lyophilization-drying. The effect of the protective medium on residual moisture of freezedrying cultures suspensions depending on the concentration of glucose and sucrose was studed. It was shown that the lowest residual moisture was attained by using glucose and sucrose in amount of 10% and if the samples of freeze-drying bacteria had been saved for one month at 4 οC the productivity did not decrease. As temperature preservation was increased the productivity of the cultures was gradually decreased and it was greatly reduced at 30 οC. So the protective medium composition was optimized for lyophilization of butanol-producing strains as follows: sucrose 10.0%; gelatin 10.0%; agar 0.02%. It was shown that the preservation of samples of freeze-drying bacteria for six months at a temperature of 4 οC did not affect the productivity of strains. It was found that cultures could use glycerol as a carbon source for butanol accumulation before lyophilization.

Full Text Available Abstract In the present paper that comprises the problems of the relation between young cultures and learning are studied, as well as the transmission problems between young people and teachers, in the first year of Middle School. It is a qualitative research which studied deeply some cases. The research makes a comparison among young students and teachers. We use two techniques of research: the semi structured interview and the discussion group. The general objectives are explore and describe the meanings that the incorporation of mass media of communication gets for the for young identities, as well as the consumption and production of young cultures and the impact which introduces their meanings into the generational transmition process between teachers and young people. From our results, we propose three discussion axes: the massification which involves for young people the consumption of young cultures in the first year of Middle School, does not allow visualize, and it could cover up interpersonal violence relations and inequality among themselves as well as their positions of cultural producers; it does exist for young people a marked dissociation in the classroom: on one side, there are the interactions between the group members and consumption/production of young cultures, and, on the other side, the school culture, and the learning process; the problem of attention/inattention of young people in the learning process in the class, is linked to the transmission process, which is produced between teachers and students in the entry into the Middle School.

Full Text Available This article describes and analyzes the “Ponto de Encontro e Cultura - PEC”, an experience developed by METUIA - University of São Paulo (USP-SP in São Paulo from 2007 to 2011 which linked occupational therapy to areas of cultural production. It was attended by the homeless, occupational therapists and students of occupational therapy. To perform the analysis of the different dimensions of the experience we were guided by the meaning-space notion. We took the space as an organizer to understand a reality in which relationships and actions are being empowered in four different spheres: culture, economics, politics and knowledge. We noted that this practice showed that there was an ongoing collective effort to build what may be called piece. This characterizes a process where the space is a common reference point which brings into play different modes of sociability that are created by the management of common symbols and codes. It was important to recognize and appreciate the plurality of modes of knowledge. Thus, we observed that, from the cultural sphere, it is possible to articulate economics, health, social assistance, politics, and knowledge production.

Inflammation and infection of bovine mammary glands, commonly known as mastitis, imposes significant losses each year in the dairy industry worldwide. While several different bacterial species have been identified as causative agents of mastitis, many clinical mastitis cases remain culture negative, even after enrichment for bacterial growth. To understand the basis for this increasingly common phenomenon, the composition of bacterial communities from milk samples was analyzed using culture independent pyrosequencing of amplicons of 16S ribosomal RNA genes (16S rDNA). Comparisons were made of the microbial community composition of culture negative milk samples from mastitic quarters with that of non-mastitic quarters from the same animals. Genomic DNA from culture-negative clinical and healthy quarter sample pairs was isolated, and amplicon libraries were prepared using indexed primers specific to the V1-V2 region of bacterial 16S rRNA genes and sequenced using the Roche 454 GS FLX with titanium chemistry. Evaluation of the taxonomic composition of these samples revealed significant differences in the microbiota in milk from mastitic and healthy quarters. Statistical analysis identified seven bacterial genera that may be mainly responsible for the observed microbial community differences between mastitic and healthy quarters. Collectively, these results provide evidence that cases of culture negative mastitis can be associated with bacterial species that may be present below culture detection thresholds used here. The application of culture-independent bacterial community profiling represents a powerful approach to understand long-standing questions in animal health and disease.

The type of culture medium and the duration of in vitro culture do not influence birthweight of ART singletons.

Does the type of in vitro culture medium or the duration of in vitro culture influence singleton birthweight after IVF/ICSI treatment? In a comparison of two culture media, neither the medium nor the duration of culture (Day 3 versus Day 5 blastocyst transfer) had any effect on mean singleton birthweight. Previous studies indicated that in vitro culture of human embryos may affect birthweight of live born singletons. Both the type of culture medium and the duration of culture may be implicated. However, these studies are small and report conflicting results. A large retrospective analysis was performed including all singleton live births after transferring fresh Day 3 or Day 5 embryos. IVF and ICSI cycles performed between April 2004 and December 2009 at a tertiary care centre were included for analysis. A total of 2098 singleton live births resulting from singleton pregnancies were included for analysis. Two different sequential embryo culture media were concurrently used in an alternating way: Medicult (n = 1388) and Vitrolife (n = 710). Maternal age, maternal and paternal BMI, maternal parity, maternal smoking, main cause of infertility, cycle rank, stimulation protocol, method of fertilization (IVF or ICSI), time in culture and number of embryos transferred were taken into account. Embryo transfers were performed either on Day 3 (n = 1234) or on Day 5 (n = 864). Singleton birthweight was the primary outcome parameter. Gestational age and gender of the newborn were accounted for in the multiple regression analysis. No significant differences in mean singleton birthweight were observed between the two culture media: Medicult 3222 g (±15 SE) and Vitrolife 3251 g (±21 SE) (P = 0.264). The mean singleton birthweight was not different between Day 3 embryo transfers (3219 ± 16 g) and Day 5 blastocyst transfers (3250 ± 19 g; P = 0.209). Multiple regression analysis controlling for potential maternal, paternal, treatment and newborn confounders confirmed the non

Gender, culture and changing attitudes: experiences of HIV in Zimbabwe.

O'Brien, Stephen; Broom, Alex

2013-01-01

This paper draws on a series of qualitative interviews with 60 people living in economically poor communities of Harare, the capital of Zimbabwe, to provide new insight into the cultural landscape of HIV. While there has been extensive exploration of gender, sexuality, culture and HIV in Zimbabwe, there is a need to revisit these issues given the country's recent political and economic history. These questions have shaped the meanings that have been created around HIV (i.e., notions of HIV-as-death and as being produced by promiscuity) and the gendered mediation of cultural practices (i.e., forms of sexual expression and treatment uptake). Drawing on the accounts from a group directly affected by HIV, we illustrate the persistence of gendered and spiritualised ideas about 'blame', 'transmission' and 'treatment' and the disproportionate burden that still falls on Zimbabwean women. We conclude with an exploration of how everyday understandings of HIV may be shifting and the ways in which marginality, discrimination and stigma may be being challenged by openness, dialogue and attitude change.

Full Text Available Discussions on sustainability began recently to focus on the consumption patterns of contemporary society as a major causative factors of social and environmental problems. Thus, the aim of this paper is to discuss some opportunities that companies have to influence these changes consumption patterns towards sustainability, taking as a basis the view discussed in studies of Rindova and Ravasi (2008 who consider firms as producers of culture. To this end, we performed a theoretical essay. The results show that companies can influence the formation of specific cultures with the symbolic construction of sustainable practices, contributing to the formation of a culture of sustainable consumption. This occurs from innovation in their ways of working, considering that evoke meanings that products appear to be influenced by strategic choices of producers, such as the concepts and philosophies of design (Ravasi; Rindova, 2008, which includes the development new technologies and practices (Michaelis, 2003 based on the principles of eco-efficiency (Barber, 2008; Clark, 2008, as well as changes in values and discourses that shape the cultures of business, government, media and civil society (Michaelis, 2003, also aligned with the ethical principles and shared environmental responsibility (Tukkeret al, 2008.

[Does work have a meaning? Basis for a positive work culture].

Science.gov (United States)

Sapelli, G

2010-01-01

From the anthropological point of view work is the expression and fulfilment of the absolute spirit in the finite sense and is, by its essence, cooperation. This obliges us to reverse the question: "does work have a meaning?", to: "does work have a meaning for workers? Does it allow self-fulfilment?" Work has a meaning if the worker's psychophysical integrity is safeguarded, if by working the individual achieves self-fulfilment as a person, if it has a sense of community. Man as an "actor" achieves self-fulfilment through technical and professional competence, thereby overcoming organizational and social conflicts. Today reducing human and social relations to an economic transaction will lead to the destruction of the meaning of life and work. The study of suicide cases in France Telecom shows that a human being inserted in the working environment wants most of all to obtain recognition. He or she will accept praise or even punishment if this is done with transparency, because the person will acknowledge in such decisions a recognition of his/herself. Many enterprises and consequently many personnel managers do not, in their essence, perceive of any meaning of work, but consider only the instrumental element. The workforce cannot be considered as a commodity, work is embodied in human beings. So either people aim at self-fulfilment or fall into anomie and depression, even to the point of the destructive impulse of elimination. The re-humanization of work and the treatment of enterprises (which are "ill" because they no longer possess any meaning of work) is the challenge that awaits us.

Culture, salience, and psychiatric diagnosis: exploring the concept of cultural congruence & its practical application.

Science.gov (United States)

Rashed, Mohammed Abouelleil

2013-07-16

Cultural congruence is the idea that to the extent a belief or experience is culturally shared it is not to feature in a diagnostic judgement, irrespective of its resemblance to psychiatric pathology. This rests on the argument that since deviation from norms is central to diagnosis, and since what counts as deviation is relative to context, assessing the degree of fit between mental states and cultural norms is crucial. Various problems beset the cultural congruence construct including impoverished definitions of culture as religious, national or ethnic group and of congruence as validation by that group. This article attempts to address these shortcomings to arrive at a cogent construct. The article distinguishes symbolic from phenomenological conceptions of culture, the latter expanded upon through two sources: Husserl's phenomenological analysis of background intentionality and neuropsychological literature on salience. It is argued that culture is not limited to symbolic presuppositions and shapes subjects' experiential dispositions. This conception is deployed to re-examine the meaning of (in)congruence. The main argument is that a significant, since foundational, deviation from culture is not from a value or belief but from culturally-instilled experiential dispositions, in what is salient to an individual in a particular context. Applying the concept of cultural congruence must not be limited to assessing violations of the symbolic order and must consider alignment with or deviations from culturally-instilled experiential dispositions. By virtue of being foundational to a shared experience of the world, such dispositions are more accurate indicators of potential vulnerability. Notwithstanding problems of access and expertise, clinical practice should aim to accommodate this richer meaning of cultural congruence.

Study of the defect structures produced by heavy ions in dielectrics by means of small angle scattering

International Nuclear Information System (INIS)

Albrecht, D.J.

1983-11-01

The aim of the present thesis was to study the defects in dielectrics produced by fast ions. For this the small angle scattering was proved as suitable method. By the production by means of the ion beam of an accelerator the defects possess a pronounced preferential direction. In scattering experiments this system of scattering centers is distinguished by its unusually strong dependence of the sample orientation according to the primary beam. This property was studied, described, and illustrated by examples, and it could by shown that from this additional informations about the scattering defects can be derived. For the first time nuclear tracks were detected by means of small angle neutron scattering. It could be shown that here the same results are obtained as by small angle X-ray scattering. The measured intensity distributions could be assigned to a mathematical model description which gives form, width, and density of the tracks in the position space. On the base of this cylinder model computer codes were established which simulate the scattering experiment regarding the main influences and calculate the expected theoretical intensity distribution. The agreement between calculated and measured scattering distributions proves the validity of the model. The parameters determined by this model, maximal change of density in the track, defect length, radial dilatation, distance of the narrowings and there depth were determined. For the main quantities, radial dilatation and maximal change of densities a simple description of the energy dependence could be given via the energy loss. (orig./HSI) [de

Stakeholder Understandings of Wildfire Mitigation: A Case of Shared and Contested Meanings

Champ, Joseph G.; Brooks, Jeffrey J.; Williams, Daniel R.

2012-10-01

This article identifies and compares meanings of wildfire risk mitigation for stakeholders in the Front Range of Colorado, USA. We examine the case of a collaborative partnership sponsored by government agencies and directed to decrease hazardous fuels in interface areas. Data were collected by way of key informant interviews and focus groups. The analysis is guided by the Circuit of Culture model in communication research. We found both shared and differing meanings between members of this partnership (the "producers") and other stakeholders not formally in the partnership (the "consumers"). We conclude that those promoting the partnership's project to mitigate risk are primarily aligned with a discourse of scientific management. Stakeholders outside the partnership follow a discourse of community. We argue that failure to recognize and account for differences in the way risk mitigation is framed and related power dynamics could hamper the communicational efforts of the collaborative partnership and impact goals for fuels reduction. We recommend ways that both groups can capitalize on shared meanings and how agency managers and decision makers can build better working relationships with interface communities and other external stakeholders.

This paper reflects our conversation at the border - a dividing line but also a potential meeting place - of organizational culture theory and institutional theory. First, we discuss the border between institutional theory and organizational culture theory by exploring two notions central to both...... - taken for grantedness and meanings. We ask what is taken for granted about institutions and organizational culture and how institutions and organizational cultures materialize? Our conversation reveals that although the notion of the taken for granted is important to institutional theory...... and organizational culture theory, what this means and implies is quite different for each. We also found that even though institutions and cultures involve meaning and evolve through meaning making, the two are understood and hence explored methodologically in quite different ways.

Estimation by limiting dilution analysis of human IL 2-secreting T cells: detection of IL 2 produced by single lymphokine-secreting T cells

International Nuclear Information System (INIS)

Vie, H.; Miller, R.A.

1986-01-01

We present here a culture method for the estimation, in human blood, of the number of lymphocytes that can respond to mitogen by producing interleukin 2 (IL 2). T cells are cultured at limiting dilutions with PHA or Con A in the presence of Epstein Barr virus-transformed human lymphoblastoid cells (EB-LCL), and supernatants are tested 3 days later for IL 2 content by a cell proliferation assay. The distribution of negative wells follows the expected Poisson single-hit relationship, suggesting that the assay is sensitive to single cells of a single limiting cell type. On average, 16.3% of peripheral blood mononuclear cells can produce IL 2 in such clonal cultures (mean of 12 determinations; SD = 5.6%). Surprisingly, irradiation (up to 2000 rad) of the titrated responder cell population diminishes the estimated frequencies by less than 50%. The ability to detect IL 2 levels in cultures containing only a single, nonproliferating T lymphocyte allows us to estimate the amount of IL 2 generated by an individual effector cell during a 3-day culture interval after mitogen stimulation. The average responding, irradiated T cell generates 0.92 pg of IL 2 (median) within 3 days. The method presented provides a straightforward way to provide independent estimates of responding cell number and of lymphokine production per cell in a variety of clinical situations

CHALLENGES IN CROSS CULTURAL ADVERTISING

Directory of Open Access Journals (Sweden)

Yuni Retnowati

2016-04-01

Full Text Available At first, marketing practitioners and academics consider standardized approaches to marketing and advertising strategies in globalization, and then some studies proved that the standardization of advertising across culture is not valid. Therefore, cross cultural advertising takes local culture into account when conveying messages in advertisements. Cross cultural understanding is very important in order to produce successful localized advertising that would reflect the cultural values and norms of intended audience. Challenge in cross cultural advertising is the problem of communicating to people of diverse cultural background. Cross cultural solutions are applied in areas such as language, communication style, images and cultural values. Cross cultural advertising is simply about using common sense and analyzing how the different elements of an advertising campaign are impacted by culture and modifying them to best speak to the target audience. Other challenges are determining between standardization and adaptation of cultural values content of advertising when facing different people from diverse cultures. In academic side, the challenge is preparing students to design advertisements that communicate effectively to diverse cultures.

Using individualism and collectivism to compare cultures--a critique of the validity and measurement of the constructs: comment on Oyserman et al. (2002).

Fiske, Alan Page

2002-01-01

Analyzing national and ethnic differences in individualism and collectivism, D. Oyserman, H. M. Coon, and M. Kemmelmeier (2002) showed that small differences in scales or samples produce markedly divergent results, challenging the validity of these constructs. The author examines the following limitations of research on individualism and collectivism: It treats nations as cultures and culture as a continuous quantitative variable; conflates all kinds of social relations and distinct types of autonomy; ignores contextual specificity in norms and values; measures culture as the personal preferences and behavior reports of individuals; rarely establishes the external validity of the measures used; assumes cultural invariance in the meaning of self-reports and anchoring and interpretation of scales; and reduces culture to explicit, abstract verbal knowledge.

The scientific interest for the search of natural means of microbial inhibitors has not faded for several years. A search of natural antibiotics, so-called bacteriocins which are produced by lactic acid bacteria (LAB), gains a huge attention of the scientists in the last century, in order to reduce the usage of synthetic food additives. Pure bacteriocins with wide spectra of antibacterial activity are promising among the natural biopreservatives. The usage of bacteriocin(s) producing LAB as starter culture for the fermentation of some food products, in order to increase their shelf-life, when synthetic preservatives are not allowable, is also possible. There are a lot of studies focusing on the isolation of new bacteriocins from traditional fermented food, dairy products and other foods or sometimes even from unusual non-food matrices. Bacteriocins producing bacteria have been isolated from different sources with the different antibacterial activity against food-borne microorganisms. This review covers the classification of bacteriocins, diversity of sources of bacteriocin(s) producing LAB, antibacterial spectra of isolated bacteriocins and analytical methods for the bacteriocin purification and analysis within the last 15 years.

Divide and conquer: intermediate levels of population fragmentation maximize cultural accumulation.

Science.gov (United States)

Derex, Maxime; Perreault, Charles; Boyd, Robert

2018-04-05

Identifying the determinants of cumulative cultural evolution is a key issue in the interdisciplinary field of cultural evolution. A widely held view is that large and well-connected social networks facilitate cumulative cultural evolution because they promote the spread of useful cultural traits and prevent the loss of cultural knowledge through factors such as drift. This view stems from models that focus on the transmission of cultural information, without considering how new cultural traits actually arise. In this paper, we review the literature from various fields that suggest that, under some circumstances, increased connectedness can decrease cultural diversity and reduce innovation rates. Incorporating this idea into an agent-based model, we explore the effect of population fragmentation on cumulative culture and show that, for a given population size, there exists an intermediate level of population fragmentation that maximizes the rate of cumulative cultural evolution. This result is explained by the fact that fully connected, non-fragmented populations are able to maintain complex cultural traits but produce insufficient variation and so lack the cultural diversity required to produce highly complex cultural traits. Conversely, highly fragmented populations produce a variety of cultural traits but cannot maintain complex ones. In populations with intermediate levels of fragmentation, cultural loss and cultural diversity are balanced in a way that maximizes cultural complexity. Our results suggest that population structure needs to be taken into account when investigating the relationship between demography and cumulative culture.This article is part of the theme issue 'Bridging cultural gaps: interdisciplinary studies in human cultural evolution'. © 2018 The Author(s).

Postcolonial constructions of HIV/AIDS: meaning, culture, and structure.

Sastry, Shaunak; Dutta, Mohan J

2011-01-01

As a field of inquiry, postcolonial health communication seeks to apprehend processes implicated in the construction of "primitive" versus "modern" with respect to issues of health. In the case of HIV/AIDS, the sociocultural representations of the disease have a profound impact on how the disease is configured medically and symbolically in dominant cultural imagination. Postcolonial constructions of disease are mobilized around the political and economic interests of the dominant power structures in global spaces. In this article, a thematic analysis of the constructions of HIV/AIDS in India in the mainstream U.S. news media was conducted. A corpus of news articles from the Lexis-Nexis database was created with the keywords "HIV," "AIDS," and "India." Three themes emerged from the study: (a) India as a site of biomedical control; (b) the economic logics of HIV/AIDS; and (c) AIDS, development, and the "Third World."

Every motifs names and variations was derived from plants and animals as source of inspiration to create many patterns of songket. Each of songket patterns have a philosophy in form of rhyme that refers to the nature of the sources of songket patterns and that philosophy reflects to the beliefs and values of Malay culture. In this research, we propose a system to facilitate an understanding of songket and the philosophy as a way to conserve Songket culture. We propose a system which is able to collect information in image songket motif variations based on feature extraction methods. On each image songket motif variations, we extracted philosophy of rhyme into impressions, and extracting color features of songket images using a histogram 3D-Color Vector quantization (3D-CVQ, shape feature extraction songket image using HU Moment invariants. Then, we created an image search based on impressions, and impressions search based on image. We use techniques of search based on color, shape and aggregation (combination of colors and shapes.

Full Text Available The relationships between national culture and organizational culture were analysed in 16 Argentinean companies. Sample was integrated by 429 employees (292 male, and 184 female, mean age 35 years old. Subjects completed, in their own work places, a socio-demographic questionnaire,a scale of national culture, and a scale of organizational practices. Results indicated that organizations adopt practices that, on average, reflect the cultural values of their country of origin. Multiple regression analysis showedthat Argentinean national companies are characterized by practices closely associated with collectivism, high power distance, and high uncertainty avoidance. In contrast, Argentinean privatized companies adopted practices most linked to individualism, low power distance, low uncertainty avoidance,low paternalism, and low fatalism. The results are discussed in light of its strengths and weaknesses, and a new agenda for future research is suggested.

Understanding culture as a means of preventing or treating health concerns is growing in popularity among social behavioral health scientists. Language is one component of culture and therefore may be a means to improve health among Indigenous populations. This study explores language as a unique aspect of culture through its relationship to other demographic and cultural variables. Participants (n = 218) were adults who self-identified as American Indian, had a type 2 diabetes diagnosis, and were drawn from two Ojibwe communities using health clinic records. We used chi-squared tests to compare language proficiency by demographic groups and ANOVA tests to examine relationships between language and culture. A higher proportion of those living on reservation lands could use the Ojibwe language, and fluent speakers were most notably sixty-five years of age and older. Regarding culture, those with greater participation and value belief in cultural activities reported greater language proficiency. PMID:29782622

A process has been developed for recombinant production of selected polypeptides using transformed insect cells cultured in a horizontally rotating culture vessel modulated to create low shear conditions. A metabolically transformed insect cell line is produced using the culture procedure regardless of genetic transformation. The recombinant polypeptide can be produced by an alternative process using virtually infected or stably transformed insect cells containing a gene encoding the described polypeptide. The insect cells can also be a host for viral production.

We studied the outcome in culture-positive and culture-negative infected total knee arthroplasty (TKA). We retrospectively reviewed 140 patients with culture-positive and 102 patients with culture-negative infected TKAs. We determined the infection control rate and clinical outcome after repeated debridement, and repeated 2-stage TKA in the culture-positive and culture-negative groups. The mean follow-up was 9.3 years (range 5-14 years) in the culture-positive group and 10.6 years (5-22) in the culture-negative group. The overall infection control rate was 56 % in both groups after the first treatment. The overall infection control rate was 90 % in the culture-positive group and 95 % in the culture-negative group. A functional knee was obtained in 90 % in the culture-positive group and 95 % in the culture-negative group. The data suggest that treatment according to the types of infection in both culture-positive and culture-negative groups after TKA controlled infection and maintained functional TKA with a firm level of fixation for most patients. Repeated debridement and repeated two-stage exchange TKA further improved infection control rates after the initial treatment and increased the likelihood of maintaining a functional TKA.

The prospects of cellulase-producing bacteria for the bioconversion of lignocellulosic biomass.

Maki, Miranda; Leung, Kam Tin; Qin, Wensheng

2009-07-29

Lignocellulosic biomass is a renewable and abundant resource with great potential for bioconversion to value-added bioproducts. However, the biorefining process remains economically unfeasible due to a lack of biocatalysts that can overcome costly hurdles such as cooling from high temperature, pumping of oxygen/stirring, and, neutralization from acidic or basic pH. The extreme environmental resistance of bacteria permits screening and isolation of novel cellulases to help overcome these challenges. Rapid, efficient cellulase screening techniques, using cellulase assays and metagenomic libraries, are a must. Rare cellulases with activities on soluble and crystalline cellulose have been isolated from strains of Paenibacillus and Bacillus and shown to have high thermostability and/or activity over a wide pH spectrum. While novel cellulases from strains like Cellulomonas flavigena and Terendinibacter turnerae, produce multifunctional cellulases with broader substrate utilization. These enzymes offer a framework for enhancement of cellulases including: specific activity, thermalstability, or end-product inhibition. In addition, anaerobic bacteria like the clostridia offer potential due to species capable of producing compound multienzyme complexes called cellulosomes. Cellulosomes provide synergy and close proximity of enzymes to substrate, increasing activity towards crystalline cellulose. This has lead to the construction of designer cellulosomes enhanced for specific substrate activity. Furthermore, cellulosome-producing Clostridium thermocellum and its ability to ferment sugars to ethanol; its amenability to co-culture and, recent advances in genetic engineering, offer a promising future in biofuels. The exploitation of bacteria in the search for improved enzymes or strategies provides a means to upgrade feasibility for lignocellulosic biomass conversion, ultimately providing means to a 'greener' technology.

Safety culture is a multi-dimensional phenomenon. Safety culture of a healthcare organization is high if it has a common stock in knowledge, values and symbols in regard to patients' safety. The article intends to define safety culture in the first step and, in the second step, demonstrate the effects of safety culture. We present the model of safety behaviour and show how safety culture can affect behaviour and produce safe behaviour. In the third step we will look at the causes of safety culture and present the safety-culture-model. The main hypothesis of this model is that the safety culture of a healthcare organization strongly depends on its communication culture and its social capital. Finally, we will investigate how the safety culture of a healthcare organization can be improved. Based on the safety culture model six measures to improve safety culture will be presented.

Vidaeff, Alex C; Kerrigan, Anthony J; Monga, Manju

2015-01-01

Culturally sensitive health care represents a real ethical and practical need in a Western healthcare system increasingly serving a multiethnic society. This review focuses on cross-cultural barriers to health care and incongruent aspects from a cultural perspective in the provision of health care. To overcome difficulties in culturally dissimilar interactions and eventually remove cross-cultural barriers to health care, a culturally sensitive physician considers his or her own identity, values, and beliefs; recognizes the similarities and differences among cultures; understands what those similarities and differences mean; and is able to bridge the differences to accomplish clear and effective communication.

Screening concepts for the isolation of biosurfactant producing microorganisms.

Science.gov (United States)

Walter, Vanessa; Syldatk, Christoph; Hausmann, Rudolf

2010-01-01

This chapter gives an overview of current methods for the isolation of biosurfactant producing microbes. The common screening methods for biosurfactants are presented. Sampling and isolation of bacteria are the basis for screening of biosurfactant producing microbes. Hydrocarbon-contaminated sites are the most promising for the isolation of biosurfactant producing microbes, but many strains have also been isolated from undisturbed sites. In subsequent steps the isolates have to be characterized in order to identify the strains which are interesting for a further investigation. Several techniques have been developed for identifying biosurfactant producing strains. Most of them are directly based on the surface or interfacial activity of the culture supernatant. Apart from that, some screening methods explore the hydrophobicity of the cell surface. This trait also gives an indication on biosurfactant production. In recent years automation and miniaturization have led to the development of high throughput methods for screening. High throughput screening (HTS) for analyzing large amounts of potential candidates or whole culture collections is reflected in the end. However, no new principals have been introduced by HTS methods.

Critical Cultural Awareness: Contributions to a Globalizing Psychology

Science.gov (United States)

Christopher, John Chambers; Wendt, Dennis C.; Marecek, Jeanne; Goodman, David M.

2015-01-01

The number of psychologists whose work crosses cultural boundaries is increasing. Without a critical awareness of their own cultural grounding, they risk imposing the assumptions, concepts, practices, and values of U.S.-centered psychology on societies where they do not fit, as a brief example from the 2004 Indian Ocean tsunami shows. Hermeneutic thinkers offer theoretical resources for gaining cultural awareness. Culture, in the hermeneutic view, is the constellation of meanings that constitutes a way of life. Such cultural meanings – especially in the form of folk psychologies and moral visions – inevitably shape every psychology, including U.S. psychology. The insights of hermeneutics, as well as its conceptual resources and research approaches, open the way for psychological knowledge and practice that are more culturally situated. PMID:24841336

2016-01-01

Physical activity is difficult to measure in individuals with COPD. The Community Healthy Activities Model Program for Seniors (CHAMPS) questionnaire demonstrated strong clinometric properties when used with the elderly and with those affected by chronic disease. Study objectives were to translate, culturally adapt the CHAMPS into French, and reexamine its test-retest reliability and construct validity in French and English Canadians with COPD. This paper presents the cross-cultural adaptation of the CHAMPS; results of its clinometric testing will be described in another article. The CHAMPS examines the degree of physical activity performed in a typical week through two summary scales, caloric expenditure and activity frequency. The CHAMPS was only in English; thus, a cross-cultural adaptation was needed to translate the CHAMPS into French for use in French Canadians with COPD. Cross-cultural adaptation consisted of forward and back translation, with expert review at each stage of translation: minor inconsistencies were uncovered and rectified. Five French participants with COPD completed the finalized Canadian French CHAMPS and participated in cognitive debriefing; no problematic items were identified. A structured and stepwise, cross-cultural adaptation process produced the Canadian French CHAMPS, with items of equivalent meaning to the English version, for use in French Canadians with COPD.

A Study on the Origins of Cultural Films in Korea: A Focus on Films by the Japanese Government-General of Korea

Directory of Open Access Journals (Sweden)

Ryeosil Kim

2014-08-01

Full Text Available The term "cultural film" was coined in Korea under the Japanese rule, and it had been used as a general term for nonfiction films since the Korean liberation until the 1980s. However, unlike the term "documentary film," cultural film contains implications of propaganda film, controlled and produced as part of cultural and public relations policies of the government, thus it had been seldom studied for a long time. The term “cultural film” did not mean a film genre in the beginning. Therefore it is impossible to conceptualize the term based on common formats or contents of the films which have been called “cultural films.” Cultural films have been generally recognized as nonfiction films, and therefore documentary films. Yet in the production and distribution sites, fiction films and even animations were considered cultural films. In order to delve into the nature of cultural film, we have to reexamine the process in which the proper noun “Cultural Film” became a common noun. This paper attempts to explore the historical context in which the term “cultural film” was coined and used in the colonial Korea, when cultural films began to be produced. I examine the overall time period in which: 1 the concept of nonfiction film was first introduced in the Motion Picture Censorship Regulation, 2 the term “cultural film” became legally stipulated at a time when national policies were being established as Korea experienced the Manchurian Incident and the Sino-Japanese War, and 3 “cultural films” were screened mandatorily as “national films” that the nation had to foster through the Japan Film Law and Chosôn Film Act.

Caprara, A; Abdulkadir, N; Idawani, C; Asmara, H; Lever, P; De Virgilio, G

2000-07-01

This paper shows how disease transmission and particularly what biomedicine calls tuberculosis are interpreted in the non-Western context of Aceh Province, Sumatra, Indonesia. It tries also to focus on factors influencing perceptions and health-seeking behaviors. Results show that what biomedicine calls TB is represented by a semantic network of illnesses. Parts of this network are clearly identified as transmissible while others are related to specific phenomena affecting the individual, such as terbuk (poisoning) or trouk (fatigue produced by hard work), and are not considered contagious. Forms of transmission are interpreted mostly through empirical and analogic categories. TB is attributed to four different aspects: (a) biomedical categories such as germ theory; (b) socio-economic conditions; (c) transgression of social rules; and (d) poisoning and the influences of supernatural powers. Health-seeking behaviors are related to the perceived causes of the disease, economic factors, and the accessibility of health services.

Prospective study on cranioplasty with individual carbon fiber reinforced polymer (CFRP) implants produced by means of stereolithography.

Wurm, Gabriele; Tomancok, Berndt; Holl, Kurt; Trenkler, Johannes

2004-12-01

The aim of this study was to evaluate the value of carbon fiber reinforced polymer (CFRP) cranial implants produced by means of 3-dimensional (3D) stereolithography (SL) and template modeling for reconstructions of complex or extensive cranial defects. A series of 41 cranioplasties with individual CFRP implants was performed in 37 patients between April 1996 and November 2002. Only patients with complex and/or large cranial defects were included, most of them having extended scarring or dural calcification and poor quality of the overlying soft-tissue cover after infection or multiple preceding operations. Involvement of frontal sinus, a known risk factor for complications after cranioplasty, was the case in 21 patients (51.2%). A computer-based 3D model of the skull with the bony defect was generated by means of stereolithography after acquisition, evaluation and transfer of the patient's helical computed tomography (CT) data. A wax template of the defect that was used to design the individual prosthesis-shape was invested in dental stone. Then, the cranial implant was fabricated out of CFRP by loosen mold. Reconstruction of defects measuring up to 17 x 9 cm was performed. The intra-operative fit of the implants was excellent in 36 (87.8%), good in 1 (2.4%), and fair in 4 (9.8%) of the cases. Problems of implant fit occurred because of extended scarring and poor quality of soft-tissue cover. Adverse reactions were observed in 5 patients (1 subdural, 1 subcutaneous hematoma, 2 infections, 1 allergic reaction). Excellent contours and a solid stable reconstruction have been maintained in 30 out of 35 remaining plates (mean follow-up 3.6 years). No adverse effects concerning postoperative imaging, the accuracy of electroencephalograms and radiation therapy have been observed. The authors believe that this relatively new technique represents an advance in the management of complex and large cranial defects, but seems less suitable for simple defects because of cost

The cultural animal human nature, meaning, and social life

Baumeister, Roy F

2005-01-01

What makes us human? Why do people think, feel, and act as they do? What is the essence of human nature? What is the basic relationship between the individual and society? These questions have fascinated both great thinkers and ordinary humans for centuries. Now, at last, there is a solid basis for answering them, in the form of the accumulated efforts and studies by thousands of psychology researchers. We no longer have to rely on navel-gazing and speculation to understand why people are the way they are - we can instead turn to solid, objective findings. This book, by an eminent social psychologist at the peak of his career, not only summarizes what we know about people - it also offers a coherent, easy-to-understand, through radical, explanation. Turning conventional wisdom on its head, the author argues that culture shaped human evolution. Contrary to theories that depict the individual's relation to society as one of victimization, endless malleability, or just a square peg in a round hole, he proposes t...

Full Text Available The aim of this article is to discuss the construction of meaning through argumentation in the teaching of History. The field research was carried out in a municipal school in Niterói – RJ. The research included 30 hours of recordings of History classes of a group of the 4th cycle of Elementary Education (also called 8th year of Elementary Education. The data analysis articulated the theoretical elements related to curriculum, language and culture. It can be pointed out a possibility of theoretical approximation of these three fields of knowledge relating them to the concrete space of the History class. The challenge is to create a dialogue among the theories from the curriculum, language and culture fields, aiming to understand the construction of meaning in the teaching of History by means of argumentation.

To screen and identify biosurfactant producers from petroleum-contaminated soil; to use response surface methodology (RSM) for medium optimization to enhance biosurfactant production; and to study the properties of the newly obtained biosurfactant towards pH, temperature and salinity. We successfully isolated three biosurfactant producers from petroleum-contaminated soil and identified them through 16S rRNA sequence analysis, which exhibit the highest similarities to Acinetobacter beijerinckii (100%), Kocuria marina (99%) and Kineococcus marinus (99%), respectively. A quadratic response model was constructed through RSM designs, leading to a 57·5% increase of the growth-associated biosurfactant production by Acinetobacter sp. YC-X 2 with an optimized medium: beef extract 3·12 g l(-1) ; peptone 20·87 g l(-1) ; NaCl 1·04 g l(-1); and n-hexadecane 1·86 g l(-1). Biosurfactant produced by Acinetobacter sp. YC-X 2 retained its properties during exposure to a wide range of pH values (5-11), high temperatures (up to 121°C) and high salinities [up to 18% (w/v) Na(+) and Ca(2+) ], which was more sensitive to Ca(2+) than Na(+). Two novel biosurfactant producers were isolated from petroleum-contaminated soil. Biosurfactant from Acinetobacter sp. YC-X 2 has good properties to a wide range of pH, high temperature and high salinity, and its production was optimized successfully through RSM. The fact, an increasing demand of high-quality surfactants and the lack of cost-competitive bioprocesses of biosurfactants for commercial utilization, motivates researchers to develop cost-effective strategies for biosurfactant production through isolating new biosurfactant producers with special surface-active properties and optimizing their cultural conditions. Two novel biosurfactant producers in this study will widen our knowledge about this kind of micro-organism. This work is the first application of RSM designs for cultural optimization of biosurfactant produced by Acinetobacter

Mills, Stacia; Xiao, Anna Q; Wolitzky-Taylor, Kate; Lim, Russell; Lu, Francis G

2017-04-01

The objective of this study was to assess whether a 1-hour didactic session on the DSM-5 Cultural Formulation Interview (CFI) improves the cultural competence of general psychiatry residents. The main hypothesis was that teaching adult psychiatry residents a 1-hour session on the CFI would improve cultural competence. The exploratory hypothesis was that trainees with more experience in cultural diversity would have a greater increase in cultural competency scores. Psychiatry residents at a metropolitan, county hospital completed demographics and preintervention questionnaires, were exposed to a 1-hour session on the CFI, and were given a postintervention questionnaire. The questionnaire was an adapted version of the validated Cultural Competence Assessment Tool . Paired samples t tests compared pre- to posttest change. Hierarchical linear regression assessed whether pretraining characteristics predicted posttest scores. The mean change of total pre- and posttest scores was significant ( p = .002), as was the mean change in subscales Nonverbal Communications ( p < .001) and Cultural Knowledge ( p = .002). Demographic characteristics did not predict higher posttest scores (when covarying for pretest scores). Psychiatry residents' cultural competence scores improved irrespective of previous experience in cultural diversity. More research is needed to further explore the implications of the improved scores in clinical practice.

The production of volatile compounds by microbial communities of cork samples taken during the cork manufacturing process was investigated. The majority of volatiles were found in samples collected at two stages: resting after the first boiling and nontreated cork disks. Volatile profiles produced by microbiota in both stages are similar. The releasable volatile compounds and 2,4,6-trichloroanisole (TCA) produced in cork-based culture medium by five isolated fungal species in pure and mixed cultures were also analyzed by gas chromatography coupled with mass spectrometry (GC-MS).The results showed that 1-octen-3-ol and esters of fatty acids (medium chain length C8-C20) were the main volatile compounds produced by either pure fungal species or their mixture. Apparently, Penicillium glabrum is the main contributor to the overall volatile composition observed in the mixed culture. The production of releasable TCA on cork cannot be attributed to any of the assayed fungal isolates.

Cognitological analysis of linguistic and extralinguistic cultural meanings reveals that there exist of specific linguistic and aesthetic formations best presented through the ‘language – culture – identity’ triad. One of the components of literary discourse is monocultural layer, which secures the continuity of national cultural tradition; researching into it, one should take into account mental and historical, psycholinguistic, sociolinguistic and other factors. Linguistic and aesthetic analysis helps to establish the system of linguistic and cultural means (metaphorization, imagery, verbal symbols, linguistic conceptualization, connotative meanings, which reveals its potential in literary texts. The lingual identity as a general notional category shows its nationally-oriented characteristics through the dichotomies of ‘addresser-addressee’ , ‘author-reader’, ‘narrator-narratee’ and is presented in the author’s idiolect.

The influence of culture of honor and emotional intelligence in the acculturation of Moroccan immigrant women.

Lopez-Zafra, Esther; El Ghoudani, Karima

2014-01-01

Migration is a normal process of people seeking new opportunities, work, or leisure in societies. The way people adapt to a new country (acculturation) is a complex process in which immigrants' evaluations about the culture of origin and their perceptions of the host country interact. The combination of these two factors produces four types of acculturation: separation, assimilation, integration, and marginalization. Several variables, such as personality, attitudes, and emotional intelligence, have been studied to help explain this process. However, the impact of a culture of honor and its interaction with other variables remains an open question that may help to explain how migrants can better adjust to their host culture. In this study, we examine the influence of the culture of honor (social) and emotional intelligence (individual) on acculturation. In a sample of 129 Moroccan women (mean age = 29, SD = 9.40) immigrants in Spain (mean time in Spain = 6 years, SD = 3.60), we investigated the relations among the variables of interest. Our results show that no significant differences emerged in the scores given for culture of honor (CH) and the acculturation strategies of the Moroccan immigrant women F(3, 99) = .233; p = .87. However women who preferred the integration strategy scored highest on emotional intelligence (EI), whereas the assimilated immigrants showed the lowest scores for EI F(3, 92) = 4.63; p = .005. Additionally, only in the case of integration does EI mediate between CH and the value given to the immigrant's own and host cultures (p <.001).

Musical meaning and social significance : techno triggers for dancing

OpenAIRE

Gadir, Tami Ester

2014-01-01

Electronically-produced dance music has only recently achieved as much visibility in the global pop music industry as ‘live’ or instrumental pop. Yet the fascination of cultural scholars and sociologists with dance music predates its rise as a product of mass culture. Much of this interest derives from early associations of dance music with marginalised groups and oppositional ideologies. It therefore follows that many explorations of dance music focus on the ways in which tech...

Space, Culture and Power in Buchi Emecheta’s Novel Called Kehinde

Directory of Open Access Journals (Sweden)

Ayla OĞUZ

2017-12-01

Full Text Available When it is considered related with power, possible meanings of space and culture gain a more importance. In postcolonial literary theory, power is introduced to be something in the hands of the people belonging to Western world. Due to this, the colonizer’s cultural knowledge about the colonized’s culture and space determines the social rank and location of non-Western people. Cultural superiority of western world over non-western world is formed due to power- knowledge relationship in postcolonial literary theory. According to Gayatri Chakravorty Spivak, knowledge in postcolonial context isn’t guiltless because it is the output of its producers. Thus, dominant power gives a new shape to such concepts like space, culture and power belonging to subordinate people. Within this context Buchi Emecheta’s interesting novel called Kehinde tells the story of a couple trying to decide on staying in London and returning to their own country, Nigeria. In the novel Kehinde as a female and her husband Albert as a male experience the multifaceted influence of both living in the center and belonging to periphery and reflect the influence of space, culture and power in their life, family and social circumference. Hence, it is anayzed in the study how Emecheta tries to show the reader the fact that power dominates everything and causes complication in man’s life referring to postcolonial literary theory while constructing the postcolonial identies in the novel.

Experimental investigation on spontaneously active hippocampal cultures recorded by means of high-density MEAs: analysis of the spatial resolution effects

Directory of Open Access Journals (Sweden)

Alessandro Maccione

2010-05-01

Full Text Available Based on experiments performed with high-resolution Active Pixel Sensor microelectrode arrays (APS-MEAs coupled with spontaneously active hippocampal cultures, this work investigates the spatial resolution effects of the neuroelectronic interface on the analysis of the recorded electrophysiological signals. The adopted methodology consists, first, in recording the spontaneous activity at the highest spatial resolution (inter-electrode separation of 21 µm from the whole array of 4096 microelectrodes. Then, the full resolution dataset is spatially down sampled in order to evaluate the effects on raster plot representation, array-wide spike rate (AWSR, mean firing rate (MFR and mean bursting rate (MBR. Furthermore, the effects of the array-to-network relative position are evaluated by shifting a subset of equally spaced electrodes on the entire recorded area. Results highlight that MFR and MBR are particularly influenced by the spatial resolution provided by the neuroelectronic interface. On high-resolution large MEAs, such analysis better represent the time-based parameterization of the network dynamics. Finally, this work suggest interesting capabilities of high-resolution MEAs for spatial-based analysis in dense and low-dense neuronal preparation for investigating signalling at both local and global neuronal circuitries.

Production of highly knotted DNA by means of cosmid circularization inside phage capsids

2007-12-01

Full Text Available Abstract Background The formation of DNA knots is common during biological transactions. Yet, functional implications of knotted DNA are not fully understood. Moreover, potential applications of DNA molecules condensed by means of knotting remain to be explored. A convenient method to produce abundant highly knotted DNA would be highly valuable for these studies. Results We had previously shown that circularization of the 11.2 kb linear DNA of phage P4 inside its viral capsid generates complex knots by the effect of confinement. We demonstrate here that this mechanism is not restricted to the viral genome. We constructed DNA cosmids as small as 5 kb and introduced them inside P4 capsids. Such cosmids were then recovered as a complex mixture of highly knotted DNA circles. Over 250 μg of knotted cosmid were typically obtained from 1 liter of bacterial culture. Conclusion With this biological system, DNA molecules of varying length and sequence can be shaped into very complex and heterogeneous knotted forms. These molecules can be produced in preparative amounts suitable for systematic studies and applications.

A bioflocculant-producing bacterium, Bacillus megaterium SP1, was isolated from biofloc in pond water and identified by using both 16S rDNA sequencing analysis and a Biolog GEN III MicroStation System. The optimal carbon and nitrogen sources for Bacillus megaterium SP1 were 20 g L -1 of glucose and 0.5 g L -1 of beef extract at 30°C and pH 7. The bioflocculant produced by strain SP1 under optimal culture conditions was applied into aquaculture wastewater treatment. The removal rates of chemical oxygen demand (COD), total ammonia nitrogen (TAN), and suspended solids (SS) in aquaculture wastewater reached 64, 63.61, and 83.8%, respectively. The volume of biofloc (FV) increased from 4.93 to 25.97 mL L -1 . The addition of Bacillus megaterium SP1 in aquaculture wastewater could effectively improve aquaculture water quality, promote the formation of biofloc, and then form an efficient and healthy aquaculture model based on biofloc technology.

Skip the (Capitalist Intermediaries: Freedom, Democracy, and Participation in the Economy and Culture

Directory of Open Access Journals (Sweden)

Forrest Perry

2015-11-01

Full Text Available A significant parallel can be drawn between a socialist argument about how to regulate property in the means of production and the liberal theorist Lawrence Lessig’s argument about how to regulate property in ideas. The two are particularly alike in the emphasis they place on the kind of participation—and the resulting freedom and democracy—enabled by having access to the means of production. Highlighting the parallel could help socialists and liberal theorists of intellectual property to see how they can advance each other’s causes: socialism could eliminate the threat of privatization of the means of producing culture that liberals like Lessig rightly worry about; and if the arguments about ownership of ideas made by Lessig and others like him end up gaining currency, then arguments about ownership of the means of production made by socialist theorists could have more resonance with larger numbers of people than is currently the case.

Structure-Activity Relationships of Bioengineered Heparin/Heparan Sulfates Produced in Different Bioreactors

Directory of Open Access Journals (Sweden)

Ha Na Kim

2017-05-01

Full Text Available Heparin and heparan sulfate are structurally-related carbohydrates with therapeutic applications in anticoagulation, drug delivery, and regenerative medicine. This study explored the effect of different bioreactor conditions on the production of heparin/heparan sulfate chains via the recombinant expression of serglycin in mammalian cells. Tissue culture flasks and continuously-stirred tank reactors promoted the production of serglycin decorated with heparin/heparan sulfate, as well as chondroitin sulfate, while the serglycin secreted by cells in the tissue culture flasks produced more highly-sulfated heparin/heparan sulfate chains. The serglycin produced in tissue culture flasks was effective in binding and signaling fibroblast growth factor 2, indicating the utility of this molecule in drug delivery and regenerative medicine applications in addition to its well-known anticoagulant activity.

ENVIRONMENTAL PHILOSOPHY AND ECOLOGICAL CULTURE

Kalimat M. Alilova

2017-01-01

Full Text Available Aim. The aim of the research is to study environmental problems related to the decline of culture, the importance of philosophy in overcoming private and personal interests as well as the unilateral approach of man in his relationship to nature. The study shows how philosophy can participate in the formation of ecological culture, a new ecological consciousness in man, while ecological culture is called upon to resist technocratic stereotypes and the course of history was aimed at preventing the biosphere from becoming deserted. Discussion. On the basis of the analysis of literary sources, we used the method of socio-cultural and socio-natural approaches based on the possibility of philosophy to introduce a new life into culture, new ecological values and new ecological principles. To solve these problems, environmental philosophy develops new theories. Representatives of different cultures, ethnic groups, nations, religions must learn to coexist with each other. We consider philosophy as a means of teaching rapprochement between peoples and creating new opportunities for understanding and improving the environmental situation. Cultural development makes it possible to assess the level of a man’s knowledge of nature, himself and the world around him. Ecological culture is a way of connecting man with nature on the basis of deeper knowledge and understanding. Philosophy says that you cannot move away from nature and be lauded over it since this will destroy culture. Rational doctrines tend to put a person above other living beings so the synthesis of philosophy with culture can have a positive ecological meaning. Conclusion. The findings obtained can be recommended for practical use in schools, starting from primary school, as well as in secondary special educational institutions and universities. It is necessary to work on the motivation and values of people, develop a common and ecological culture. Only a cultured person can move from

Victor V. Revin

2016-02-01

Full Text Available The possibility of preparing molding-bioengineered materials, such as woodchip boards (WCB, from sawdust using technical lignosulfonate (LGS, a wood waste product, and a culture liquid (CL of levan microbial polysaccharide producer by Azotobacter vinelandii D-08 is explored in this article. The parameters of the derived materials are comparable to those of traditional materials made from toxic phenol-formaldehyde resins. The various physical and mechanical characteristics of the materials depend on the quantity of the bonding agent used for the preparation. Adding a culture liquid increases the humidity resistance of the molding materials. Using electron microscopy and X-ray micro-tomography, it is clear that the structure of woodchip boards become more homogeneous without microcracks with the addition of CL. The strength of the best samples prepared was approximately 24 to 29 MPa with a density of 1170 to 1255 kg/m3 and a swell on wetting of 6.7%. During hot pressing, noticeable changes were observed by Fourier transform infrared spectroscopy (FTIR at frequencies typical of LGS sulfonic-acid groups, levan fructose fragments, and skeletal vibrations of a syringal/guaiacyl core in lignin and of C-H groups of hemicelluloses. This indicates the involvement of these functional groups in the process of binding wood particles with hot pressing.

Full Text Available This paper presents a comparative analysis of relevant methodological essence of "traditional" and "new" cultural geography. In the introduction is given an explanation of philosophic concepts of space, environment, place and the region in cultural geography. In second section is analyzed the meaning of civilization and the genesis of geography of civilization (géographie de civilisation. Special attention is on features of geographical posibilism as methodological paradigm, and the concept of cultural landscape as the essence of classical geography of culture and civilization. After this part are researched specific characteristics of certain academic schools and methodological perspectives in cultural geography. Postmodern paradigm and essence of "new" cultural geography are in the main focus. Postmodernism is changing the meaning of the basic concepts in cultural geography, which are analyzed in the introduction, such as space, culture, cultural region, cultural landscape and others. "New" cultural geography reassessed social and moral issues associated with the characteristics of the postmodern era. In this regard, methodological paradigm must be changed. This ascertainment is based on the interpretation of humanistic geography, where the emphasis is on the interpretation of cultural symbols, causal link and the "spirit of place" (Spiritus Loci. In accordance with modern conceptions of human in psychological notion, there are at least three theoretical directions, which find resonance in the appropriate cultural geography: behaviorism, psychoanalytic concept and cognitive concept - gestaltism and geography of perception. In conclusion is emphasized the need of finding a dialectical unity in "classical" and "new" cultural geography. [Projekat Ministarstva nauke Republike Srbije, br. 176017

2018-02-01

We propose a three-dimensional (3D) imaging platform based on lens-free microscopy to perform multi-angle acquisitions on 3D cell cultures embedded in extracellular matrix (ECM). We developed algorithms based on the Fourier diffraction theorem to perform fully 3D reconstructions of biological samples and we adapted the lens-free microscope to incubator conditions. Here we demonstrate for the first time, 3D+time lens-free acquisitions of 3D cell culture over 8 days directly into the incubator. The 3D reconstructed volume is as large as 5 mm3 and provides a unique way to observe in the same 3D cell culture experiment multiple cell migration strategies. Namely, in a 3D cell culture of prostate epithelial cells embedded within a Matrigel® matrix, we are able to distinguish single cell 'leaders', migration of cell clusters, migration of large aggregates of cells, and also close-gap and large-scale branching. In addition, we observe long-scale 3D deformations of the ECM that modify the geometry of the 3D cell culture. Interestingly, we also observed the opposite, i.e. we found that large aggregates of cells may deform the ECM by generating traction forces over very long distances. In sum we put forward a novel 3D lens-free microscopy tomographic technique to study the single and collective cell migrations, the cell-to-cell interactions and the cell-to-matrix interactions.

Research around the world is now beginning to validate the theory of Cultural Care as an important means to provide culturally congruent care to clients, families, and groups of diverse cultures. Knowledge of Leininger's Theory of Cultural Care Diversity and Universality can provide meaningful care to clients who have different traditional and current beliefs and values. The Leininger Sunrise Model can serve as a valuable guide to discover care meanings and practices related to the theory, and to provide practical and meaningful culture specific care decisions and actions by nurses. The three major modes of action, namely, cultural care maintenance or preservation, accommodation or negotiation, and repatterning or restructuring, are important differential means to provide culturally congruent care to clients within their own cultural setting. This article considers the application of such care for the Hausa of Northwest Africa.(ABSTRACT TRUNCATED AT 250 WORDS)

Museology and heritage in contemporary cities: a thesis on city management from the perspective of culture and memory preservation

Directory of Open Access Journals (Sweden)

Heloisa Helena Fernandes Gonçalves da Costa

2012-04-01

Full Text Available Essentialy considered a space to live, the contemporary cities are complexes territories where memory and heritage have no effective representative function. The main objective of this paper is to analyze the emergence of the 'cultural health', a new concept supported by the relationship between museology, heritage and citizenship. The research was based on fieldwork experience and on memory studies of adults and elderly people that live in urban areas, where they can observe the symbolic meaning of the monuments and similars objects within the museum cities and the cultural landscapes. The way that museums and monuments are inserted in civil society and their power to produce values and cultural codes make them part of the process to promote identities and citizenship. Also, this process can improve the cultural health, the self-esteem and the quality of social interaction. These elements are essential for the building of healthy cities.

to interpret the meanings patients with type 2 diabetes mellitus assign to health education groups. ethnographic study conducted with Hyperdia groups of a healthcare unit with 26 informants, with type 2 diabetes mellitus, and having participated in the groups for at least three years. Participant observation, social characterization, discussion groups and semi-structured interviews were used to collect data. Data were analyzed through the thematic coding technique. four thematic categories emerged: ease of access to the service and healthcare workers; guidance on diabetes; participation in groups and the experience of diabetes; and sharing knowledge and experiences. The most relevant aspect of this study is the social use the informants in relation to the Hyperdia groups under study. the studied groups are agents producing senses and meanings concerning the process of becoming ill and the means of social navigation within the official health system. We expect this study to contribute to the actions of healthcare workers coordinating these groups given the observation of the cultural universe of these individuals seeking professional care in the various public health care services.

The cultural psychology endeavor to make culture central to psychology: Comment on Hall et al. (2016).

Science.gov (United States)

Dvorakova, Antonie

2016-12-01

When Hall, Yip, and Zárate (2016) suggested that cultural psychology focused on reporting differences between groups, they described comparative research conducted in other fields, including cross-cultural psychology. Cultural psychology is a different discipline with methodological approaches reflecting its dissimilar goal, which is to highlight the cultural grounding of human psychological characteristics, and ultimately make culture central to psychology in general. When multicultural psychology considers, according to Hall et al., the mechanisms of culture's influence on behavior, it treats culture the same way as cross-cultural psychology does. In contrast, cultural psychology goes beyond treating culture as an external variable when it proposes that culture and psyche are mutually constitutive. True psychology of the human experience must encompass world populations through research of the ways in which (a) historically grounded sociocultural contexts enable the distinct meaning systems that people construct, and (b) these systems simultaneously guide the human formation of the environments.

Is «cultural tourism» actually «cultural»?

Directory of Open Access Journals (Sweden)

David Senabre López

2007-09-01

Full Text Available The epithet of cultural has been used as an adulterated attraction for a kind of leisure activity dressed up in all its finery: the type of tourism that is linked to the historic heritage. The tourism client sets off for an apparent happiness by means of a manipulated, abridged or smoothen by-product of a civilisation’s real historic essence, without paying any attention to –or passively assumin– the mercantilist machinery that it is part of. The label of «cultural» is often distorted by the superficial made of it.Should other forms of tourism that do not involve heritage –such as beach holi- days, rural tourism or mountain holidays– be considered as ‘a-cultural’? Can anybody acquire any culture just by travelling or culture is something that must be carried on by the traveller so as to properly value what he sees? Surveys on cultural tourism so far have concentrated on boosting its efficiency from a business point of view –which is a wrong approach– instead of analysing the phenomenon from a humanistic perspective. Key words: Tourism, Cultura, Leisure, Heritage.

Generation of organotypic raft cultures from primary human keratinocytes.

Science.gov (United States)

Anacker, Daniel; Moody, Cary

2012-02-22

The development of organotypic epithelial raft cultures has provided researchers with an efficient in vitro system that faithfully recapitulates epithelial differentiation. There are many uses for this system. For instance, the ability to grow three-dimensional organotypic raft cultures of keratinocytes has been an important milestone in the study of human papillomavirus (HPV)(1). The life cycle of HPV is tightly linked to the differentiation of squamous epithelium(2). Organotypic epithelial raft cultures as demonstrated here reproduce the entire papillomavirus life cycle, including virus production(3,4,5). In addition, these raft cultures exhibit dysplastic lesions similar to those observed upon in vivo infection with HPV. Hence this system can also be used to study epithelial cell cancers, as well as the effect of drugs on epithelial cell differentiation in general. Originally developed by Asselineau and Prunieras(6) and modified by Kopan et al.(7), the organotypic epithelial raft culture system has matured into a general, relatively easy culture model, which involves the growth of cells on collagen plugs maintained at an air-liquid interface (Figure 1A). Over the course of 10-14 days, the cells stratify and differentiate, forming a full thickness epithelium that produces differentiation-specific cytokeratins. Harvested rafts can be examined histologically, as well as by standard molecular and biochemical techniques. In this article, we describe a method for the generation of raft cultures from primary human keratinocytes. The same technique can be used with established epithelial cell lines, and can easily be adapted for use with epithelial tissue from normal or diseased biopsies(8). Many viruses target either the cutaneous or mucosal epithelium as part of their replicative life cycle. Over the past several years, the feasibility of using organotypic raft cultures as a method of studying virus-host cell interactions has been shown for several herpesviruses, as

Cultural Considerations: Pharmacological and Nonpharmacological Means for Improving Blood Pressure Control among Hispanic Patients

Neela K. Patel

2012-01-01

Full Text Available Cardiovascular disease is a leading cause of morbidity and mortality in the United States, and its prevention and treatment remain a priority for the medical community. Ethnic variations account for some differences in the prevalence of hypertension and blood pressure (BP control rates among Hispanics, indicating the need for culturally appropriate management models. Aggressive treatment strategies are key to achieving optimal BP control in high-risk Hispanic patients. Hypertension in this ethnic group continues to be a major health concern. Of note, when provided access to comprehensive care, Hispanics demonstrate similar response rates to treatment as the majority of non-Hispanic whites. This highlights the importance of effective, culturally responsive hypertension management among high-risk Hispanic patients for achieving observable, positive health outcomes.

Symbol/Meaning Paired-Associate Recall: An “Archetypal Memory” Advantage?

Science.gov (United States)

Sotirova-Kohli, Milena; Opwis, Klaus; Roesler, Christian; Smith, Steven M.; Rosen, David H.; Vaid, Jyotsna; Djonov, Valentin

2013-01-01

The theory of the archetypes and the hypothesis of the collective unconscious are two of the central characteristics of analytical psychology. These provoke, however, varying reactions among academic psychologists. Empirical studies which test these hypotheses are rare. Rosen, Smith, Huston and Gonzales proposed a cognitive psychological experimental paradigm to investigate the nature of archetypes and the collective unconscious as archetypal (evolutionary) memory. In this article we report the results of a cross-cultural replication of Rosen et al. conducted in the German-speaking part of Switzerland. In short, this experiment corroborated previous findings by Rosen et al., based on English speakers, and demonstrated a recall advantage for archetypal symbol meaning pairs vs. other symbol/meaning pairings. The fact that the same pattern of results was observed across two different cultures and languages makes it less likely that they are attributable to a specific cultural or linguistic context.

Recent negotiation research has produced a groundswell of insights about the effects of culture on negotiation. Yet, few frameworks exist to organize the findings. This review integrates recent research using a two-dimensional framework: The first dimension organizes the research into that which has taken: (1) a comparative intracultural approach, versus (2) an intercultural approach. The second dimension organizes the research by its emphasis on: (1) inputs into negotiation, (2) processes of negotiating, and (3) outcomes of negotiation. This framework helps to organize extant research and produces novel insights about the connections between disparate research streams, revealing both commonalities and culture-specificities in negotiation strategy and outcomes and suggesting that intercultural negotiations are difficult but not insurmountable. We conclude by discussing several areas in which more research on culture and negotiation is urgently needed in today's globalizing world. Copyright © 2015 Elsevier Ltd. All rights reserved.

Is there a difference in birthweight distribution in ART singletons born after IVF culture in two different culture media? There is no effect of culture media on both crude and adjusted birthweight distributions in ART singletons from nulliparous mothers. Studies on human ART singletons have reported a difference in birthweight in singletons following IVF culture in different culture media. However, other studies comparing different culture media have not shown any significant differences in birthweight. This study was a retrospective comparison of birthweights in IVF/ICSI singletons conceived after fresh embryo transfer following embryo culture in Cook or Medicult medium and in a national cohort of naturally conceived singletons in nulliparous women. The study compares four independent groups consisting of singletons in nulliparous women from Cook-d2: 2-day culture in Cook medium at Rigshospitalet (n = 974), Medicult-d2: 2-day culture in Medicult EmbryoAssist medium at Rigshospitalet (n = 147), Medicult-d3: 3-day culture in Medicult EmbryoAssist medium with and without added GM-CSF (n = 204), and DK: pregnancies from the Danish birth registry (n = 106842). The study compares the birthweights of singletons from nulliparous women in the four independent groups mentioned above; Cook-d2: Medicult-d2: Medicult-d3: and DK. In addition, distributions of large and small for gestational age infants were compared between the groups and a multiple linear regression analysis was used to determine which factors determined birthweight. We found no significant difference in the crude birthweight distributions between singletons born after culture in Cook-d2 or Medicult-groups. Singleton girls from the Cook-d2 group weighed 3302 ± 28 g, versus 3252 ± 76 in the Medicult-d2 group (difference 50 g; P = 0.547). Singleton boys from the Cook-d2 group weighed 3430 ± 27 g, versus 3354 ± 56 in the Medicult-d2 group (difference 76 g; P = 0.279). In the background population, mean

A direct pathway to children's literacy forms through the development of shared meaning. Proto-narrative construction and social pretend play with peers can be important tools in children's developing emergent literacy. Early child-care programs provide relatively little unstructured time. To reemphasize shared meaning in the lives of children,…

Methodology for understanding Indian culture

Methods of understanding cultures, including Indian culture, are embedded in a broad spectrum of sociocultural approaches to human behavior in general. The approaches examined in this paper reflect evolving perspectives on Indian culture, ranging from the starkly ethnocentric to the largely...... eclectic and integrative. Most of the methods herin discussed were developed in the West and were subsequently taken up with or without adaptations to fit the Indian context. The paper begins by briefly reviewing the intrinsic concept of culture. It then adopts a historical view of the different ways...... and means by which scholars have construed the particular facets of Indian culture, highlighting the advantages and disadvantages of each. The final section concludes with some proposals about the best ways of understnding the complexity that constitutes the Indian cultural reality....

What happens when two successful car producers with different know-how and a different knowledge background, different work processes, different product portfolios and last but not least, completely different corporate cultures decide to merge? Daimler-Benz and Chrysler wanted to strengthen their position during economically difficult times for the car industry by juggling the crisis together and they hoped to be able to combine their strengths. Therefore the two companies decided to fuse in 1998. But not even ten years later Daimler-Benz once again sold all its shares of the Chrysler division. The dream to become the third biggest car producer of the world, behind General Motors and Ford, burst. The expected and wished for synergy effects stayed out. Instead of gaining competitive advantage over their competitors, the merger rushed the two car producers ever deeper into the crisis and did not provide the companies with the necessary tools to overcome the recession. The presented paper deals with the failed merger of the German company Daimler-Benz with the U.S. American company Chrysler

Use of a bacteriocin-producing lactococcal strain to control Listeria monocytogenes in jben. A Lactococcus lactis strain isolated from lben was shown, by the spot technique, to produce a bacteriocin different from nisin. Inhibitory activity of the bacteriocin-producing strain against Listeria monocytogenes was investigated in jben, made from cow's milk fermented with the producer organism and contaminated with 104 or 107 cfu ml-1. Listeria counts were monitored during manufacture, and during conservation at room and at refrigeration temperatures. Results showed that the pathogen was reduced by 2.7 logarithmic units after 30 h of jben processing when the initial inoculum of 107 cfu ml(-1) was used. For the initial inoculum of 104 cfu ml(-1), the bacterium was completely eliminated at 24 h. Furthermore, the use of the bacteriocin-producing starter culture extended the shelf-life of jben by 5 days. In situ production of the lactococcal bacteriocin is an efficient biological means of controlling L. monocytogenes in jben and of allowing shelf-life extension. The proposed technology will essentially benefit minimally processed dairy products and those made with raw milk.
