Enhancing food safety in developing countries, such as Indonesia, poses more challenges, especially those of the small- and medium-scale. Various food safety systems are available and readily implemented in the food industry. However, to ensure the effectiveness of such systems, pre-requisite programs should be applied prior to the implementation of food safety system. One of the most acknowledged pre-requisite program is Good Manufacturing Practices (GMP). The aim of this study is to assess the GMP compliance of some small-scale food companies in East Java. Three types of traditional food product were selected, include tempe chips, palm sugar, and instant herbal drink. A survey involving three companies for each type of traditional food was conducted. Data was obtained through observation and assessment based on tabulated criteria in GMP criteria. In essential, the result revealed the compliment level of the food companies being surveyed. There was different level of compliment between each type of the food industry, where the palm sugar industry had the lowest level of compliment compared to the other two. This difference is due to the food safety awareness, social and cultural influences, and also knowledge on food safety and hygiene practice.

Describe the extent to which tobacco industry marketing tactics incorporated American Indian culture and traditional tobacco. A keyword search of industry documents was conducted using document archives from the Truth Tobacco Documents Library. Tobacco industry documents (n=76) were analysed for themes. Tobacco industry marketing tactics have incorporated American Indian culture and traditional tobacco since at least the 1930s, with these tactics prominently highlighted during the 1990s with Natural American Spirit cigarettes. Documents revealed the use of American Indian imagery such as traditional headdresses and other cultural symbols in product branding and the portrayal of harmful stereotypes of Native people in advertising. The historical and cultural significance of traditional tobacco was used to validate commercially available tobacco. The tobacco industry has misappropriated culture and traditional tobacco by misrepresenting American Indian traditions, values and beliefs to market and sell their products for profit. Findings underscore the need for ongoing monitoring of tobacco industry marketing tactics directed at exploiting Native culture and counter-marketing tactics that raise awareness about the distinction between commercial and traditional tobacco use. Such efforts should be embedded within a culturally sensitive framework to reduce the burden of commercial tobacco use. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Full Text Available Throughout Europe and within various historical and socio-economic conditions, Slovaks have formed many enclaves and diasporas. In order to investigate common cultural and ethnic characteristics and/or differences between Slovaks in Slovakia and the various diasporas that they formed in relationship with majorities of their host countries, we suggest the usage of the cartographic method. Namely, during the 1997-1999 the Institute of Ethnology of the Slovakian Academy of Science used the cartographic method to analyze various complex questions relating to the traditional culture and ethnic history of many Slovakian minorities in the countries of Central Europe: in Poland, Ukraine, Romania and Hungary. The project was named Traditional Culture of Slovakian Minorities in Central Europe - the application of ethno-cartographic method in research and comparison of cultural manifestation. The project yield positive results and in 2000-2002 proceeded with yet another scientific project: Traditional Culture of Slovakian Minorities in Southeastern Europe - the application of the cartographic method in research and comparison of cultural manifestations once more, the data were obtained on the traditional folk culture of the Slovakian enclaves in Vojvodina and Croatia. The cartographic method used in both projects enabled researchers to document relevant data in a relatively short period of time. A solid foundation was created for a scientific synthesis of selected topics that deal with the traditional culture of Slovakian minorities in Central and Southeastern Europe, and its comparisons with the parent country culture. The cartographic method is widely used in Slovakia, in some 250 sites. Further, the scientific project of the Institute of Ethnology of the Slovakian Academy of Science named Traditional Culture of Slovakian Minorities in Central and Southern Europe as an integral part of their cultural inheritance (In between cultural stability and

Full Text Available Malaysia has many ethnic groups, and each ethnic group has own custom and tradition that most Malaysians are not aware, especially traditional dances. Among the Malaysian states, Sabah and Sarawak, situated in the Borneo Island have the most diverse ethnic groups in Sarawak. It has more than 30 ethnic groups. Each of the ethnic groups has its own language, cultures and lifestyle. In this regards, this research focuses on the main ethnic groups of Sarawak which are Orang Ulu, Malays, Melanau, Bidayuh, Chinese and Ibans. The aim of this study is to investigate the level of awareness among the Management and Science University (MSU students regarding their level of awareness and knowledge about traditional dances of Sarawak. The data were gathered by distributing questionnaires among MSU students. The data were then analysed using SPSS system version 18.0. Results concluded that, most of MSU students have limited knowledge about Sarawak traditional dances. Interests, internet, performing arts clubs and family background are the independent variable factors to learn and gain knowledge about Sarawak traditional dances. The level of awareness among MSU students towards Sarawak traditional dances can be enhanced through events and special occasions to increase level of awareness towards Sarawak cultures. The government plays a major role in introducing Sarawak cultures to the whole of Malaysia. Future studies could focus on factors that influence the level of awareness towards Sarawak traditional dances, and the contribution of Sarawak’s traditional dances to Malaysia’s cultural and heritage tourism.

The compatibility of CHO cell culture medium formulations with all stages of the bioprocess must be evaluated through small-scale studies prior to scale-up for commercial manufacturing operations. Here, we describe the development of a bespoke small-scale device for assessing the compatibility of culture media with a widely implemented upstream viral clearance strategy, high-temperature short-time (HTST) treatment. The thermal stability of undefined medium formulations supplemented with soy hydrolysates was evaluated upon variations in critical HTST processing parameters, namely, holding times and temperatures. Prolonged holding times of 43 s at temperatures of 110 °C did not adversely impact medium quality while significant degradation was observed upon treatment at elevated temperatures (200 °C) for shorter time periods (11 s). The performance of the device was benchmarked against a commercially available mini-pilot HTST system upon treatment of identical formulations on both platforms. Processed medium samples were analyzed by untargeted LC-MS/MS for compositional profiling followed by chemometric evaluation, which confirmed the observed degradation effects caused by elevated holding temperatures but revealed comparable performance of our developed device with the commercial mini-pilot setup. The developed device can assist medium optimization activities by reducing volume requirements relative to commercially available mini-pilot instrumentation and by facilitating fast throughput evaluation of heat-induced effects on multiple medium lots.

Previous work has suggested that ethnic minority women have more negative attitudes to cosmetic surgery than British Whites, but reasons for this are not fully understood. To overcome this dearth in the literature, the present study asked 250 British Asian and 250 African Caribbean university students to complete measures of attitudes to cosmetic surgery, cultural mistrust, adherence to traditional cultural values, ethnic identity salience, self-esteem, and demographics. Preliminary analyses showed that there were significant between-group differences only on cultural mistrust and self-esteem, although effect sizes were small (d values = .21-.37). Further analyses showed that more negative attitudes to cosmetic surgery were associated with greater cultural mistrust, stronger adherence to traditional values, and stronger ethnic identity salience, although these relationships were weaker for African Caribbean women than for British Asians. These results are discussed in relation to perceptions of cosmetic surgery among ethnic minority women.

2015-01-01

Full Text Available This is the study of traditional rice planting ritual discourse of the traditional farming community of Bayan, North Lombok in an ethno-pragmatic perspective.  It is specifically aimed at describing the cultural norms and their meaning configurations.  The theory used in the study is the cultural scripts developed by Wierzbicka (2002a considering that cultural norms constitute rules and regulations in social interaction practices. They can be investigated from the use of grammatical aspects of language and linguistic routines which are context-bound. They can be configured by paraphrasing in simple and mini language using single space. The results of the study showed that there were some cultural norms found on the traditional rice planting ritual discourse of the traditional farming community of Bayan, North Lombok. They included: (1 asserting thought and hope, (2 respecting other entities, (3 apologizing, (4 promising, and (5 giving advice. The configuration of these cultural norms was in accordance with the understanding of local cultural scripts and wisdom in terms of rituals of the local farming system. The configuration is constructed in low-level script with components of “when” and “if”. It contains the aspects of thinking, speaking, and doing. It is derived from the semantic primes of both evaluation and perception.

Some relations among cultural traditions, nuptiality and fertility.

Science.gov (United States)

Coale, A J

1991-01-01

Demographic transition is a period characterized by changes in mortality and fertility that accompany modernization and economic development. Typical features of age at first marriage among populations in different stages of demographic transition are described including the changes in age at marriage, the association between marriage age changes and fertility control, and the role of cultural and traditional behavior in influencing age at marriage and initiation of fertility control. In the Western model, there was a late age of marriage for women between 23 and 28 years old, and a high proportion of women who remain single until 50 years old (10-25%). The Eastern European model was one of moderately early marriage (mean age 19-22) and a small proportion remaining single (2-5%). The third model was Asian and African with early (mean age of 18 years) and universal marriage (1% unmarried). The reduction in number married was associated with reduced fertility. The differences between the Eastern and Western models were in household composition. In premodern societies, any fertility control present was governed by custom and limited biomedical influences such as duration of breast feeding and sexual abstention following a birth. These practices were not considered deliberate fertility control. The mean age of marriage in India was 14 years until 1941 and slowly reached 18.4 years in 1981. Fertility did not begin to decline until after 1960. Examples are given of the close association between marital fertility that is voluntary controlled and mean age at marriage. The influences of culture and traditions on the association between mean age of marriage and voluntary fertility control are shown by examples from the Soviet Union. The eastern part of the Soviet Union experienced a rise in mean age of marriage and an unsustained decline in marital fertility similar to that in China. There were also similarities in nuptiality and fertility between other areas in the Soviet

Oral Transmission: A Marriage of Music, Language, Tradition, and Culture

Emma E. Patterson

2015-06-01

Full Text Available There are a number of misunderstandings about ancient oral transmission that negatively affect the way musicians view music history but also the process of how music was and currently is conceived, recorded, and shared. A common misconception is that oral transmission of music is an ancient practice that occurred before written notation of music was developed. However, I seek to prove that there is a false dichotomy between oral transmission and written notation and I focus on the changing definition and importance of oral tradition. Firstly, I discuss the misconceptions of ancient oral transmission. Secondly, I examine the continuing development of research and definitions of oral transmission—which is changing our concept of ancient as well contemporary oral traditions. Thirdly, I demonstrate how these traditions are still relevant in present, late modern times. Thoughout this discussion I examine and engage with the pivotal specialists and research that has developed our view of oral tradition through time. To better understand these scholars’ commentary as well as my own, it is important to note the combined concepts of oral and aural tradition. Oral culture refers to what is spoken and sung, and aural culture refers to what is heard and comprehended. Both are necessary for effective transmission to occur, and oral and aural methods are almost always simultaneously present in most societies. When aural culture is discussed here, it refers to the combination of both elements and is closely related to aural tradition. The most notable terms to differentiate are oral transmission and oral tradition. Typically oral transmission refers to the basic action of passing information, in this case music, through oral and aural means. Oral tradition, however, is the more general concept that synthesizes oral transmission, tradition, and culture. Despite misconceptions that music was primitive before composers started documenting it, oral

Small-scale power plant potential in Finland

International Nuclear Information System (INIS)

Helynen, S.

1993-01-01

The presentation discusses the small-scale power plant potential in Finland. The study of the potential is limited to W-scale power plants producing both electric power and heat using solid fuels. The basic power plant dimensioning and electric power load determination is based on traditional boiler and gas turbine technology. The possible sites for power plants are communities using district heating, and industrialized sites needing process steam or heat. In 1990 70 % (17 TWh) of district heat was produced by gas turbines. Ten communities have an own back-pressure power plant, and 40 communities buy heat from industrial plants, owing back-pressure power generation. Additionally about 40 communes buy district heat from companies, owned by power companies and industry. Estimates of small-scale power plant potential has been made plant wise on the basis of district heat loads and industrial heat needs. The scale of the plants has been limited to scale 3 MWe or more. The choosing of the fuel depends on the local conditions. The cheapest indigenous fuels in many communes are industrial wood wastes, and both milled and sod peat. The potential of steam technology based small-scale power plants has been estimated to be about 50 plants in 1992/1993, the total power of which is 220-260 MW. The largest estimate is base situation, in which there would be energy cooperation between the communes and industry. The fuel used by the power plants would be about 5.4-6.6 TWh/a corresponding to 270-330 million FIM/a. The total investment costs of the plants would be about 2.0 billion FIM. The plants would employ about 250 persons, and the fuel supply (wood or peat) about 100 persons

The Use of Starter Cultures in Traditional Meat Products

2017-01-01

Full Text Available Starter cultures could play an essential role in the manufacture of traditional cured meat products. In order to achieve objectives related to meat products’ quality and safety improvement, the selection of particular strains constituting a starter culture should be carried out in the context of its application, since its functionality will depend on the type of sausage and process conditions. Also, strain selection should comply with particular requirements to warrant safety. The aim of the current review is to update the knowledge on the use of starter cultures in traditional meat products, with focus on dry-fermented products. In this manuscript, we will try to give answers to some relevant questions: Which starter cultures are used and why? Why are LAB used? What are their role and their specific mode of action? Which other groups of microorganisms (bacteria and fungi are used as starter cultures and how do they act? A particular revision of omics approach regarding starter cultures is made since the use of these techniques allows rapid screening of promising wild strains with desirable functional characteristics, enabling the development of starter cultures better adapted to the meat matrix.

Cell cultures are developed from tissue samples and then disaggregated by mechanical, chemical, and enzymatic methods to extract cells suitable for isolation of viruses. With the recent advances in technology, cell culture is considered a gold standard for virus isolation. This paper reviews the evolution of cell culture methods and demonstrates why cell culture is a preferred method for identification of viruses. In addition, the advantages and disadvantages of both traditional and modern cell culture methods for diagnosis of each type of virus are discussed. Detection of viruses by the novel cell culture methods is considered more accurate and sensitive. However, there is a need to include some more accurate methods such as molecular methods in cell culture for precise identification of viruses.

Chinese Confucian culture and the medical ethical tradition.

Guo, Z

1995-08-01

The Confucian culture, rich in its contents and great in its significance, exerted on the thinking, culture and political life of ancient China immense influences, unparalleled by any other school of thought or culture. Confucian theories on morality and ethics, with 'goodness' as the core and 'rites' as the norm, served as the 'key notes' of the traditional medical ethics of China. The viewpoints of Confucianism on benevolence and material interests, on good and evil, on kindheartedness, and on character cultivation were all inherited by the medical workers and thus became prominent in Chinese traditional medical ethics. Hence, it is clear that the medical profession and Confucianism have long shared common goals in terms of ethics. Influenced by the excellent Confucian thinking and culture, a rather highly-developed system of Chinese traditional medical ethics emerged with a well-defined basic content, and the system has been followed and amended by medical professionals of all generations throughout Chinese history. This system, just to mention briefly, contains concepts such as the need: to attach great importance to the value of life; to do one's best to rescue the dying and to heal the wounded; to show concern to those who suffer from diseases; to practise medicine with honesty; to study medical skills painstakingly; to oppose a careless style of work; to comfort oneself in a dignified manner; to respect local customs and to be polite; to treat patients, noble or humble, equally, and to respect the academic achievements of others, etc. Of course, at the same time, Confucian culture has its own historical and class limitations, which exerted negative influences on traditional medical ethics. Now, if we are to keep up with the development of modern medicine, a serious topic must be addressed. That is how to retain the essence of our traditional medical ethics so as to maintain historic continuity and yet, at the same time, add on the new contents of medical

Gypsies and Travellers living in Britain today are culturally diverse and made up of differing groups. The aim of this paper is to describe the different groups and sub-groups, and look at similarities and differences between these groups while highlighting the discrimination and prejudice experienced by the Travelling community as a whole. Although there is no one culture common to all these groups, they share an ancient tradition of 'nomadism' and an oral tradition of passing on knowledge. Gypsies and Irish Travellers are recognised as ethnic minorities under the Equality Act 2010 and it is estimated that there are between 200,000 and 300,000 living in the UK. This paper offers an account of how a specialist health visitor working in the south Gloucestershire area has attempted to reduce prejudice and discrimination experienced by Gypsies and Travellers by raising awareness of their cultural issues. It will also focus on how to ensure services take into account the needs of Gypsies and Travellers.

Despite a growing recognition of cultural connectedness as an important protective factor for First Nations (FN) peoples' health, there remains a clear need for a conceptual model that organizes, explains, and leads to an understanding of the resiliency mechanisms underlying this concept for FN youth. The current study involved the development of the Cultural Connectedness Scale (CCS) to identify a new scale of cultural connectedness. A sample of 319 FN, Métis, and Inuit youths enrolled in Grades 8-12 from reserve and urban areas in Saskatchewan and Southwestern Ontario, Canada, participated in the current study. A combination of rational expert judgments and empirical data were used to refine the pool of items to a set that is a representative sample of the indicators of the cultural connectedness construct. Exploratory factor analysis (EFA) was used to examine the latent structure of the cultural connectedness items, and a confirmatory factor analysis was used to test the fit of a more parsimonious version of the final EFA model. The resulting 29-item inventory consisted of 3 dimensions: identity, traditions, and spirituality. Criterion validity was demonstrated with cultural connectedness dimensions correlating well with other youth well-being indicators. The conceptualization and operationalization of the cultural connectedness has a number of potential applications both for research and prevention. This study provides an orienting framework that guides measurement of cultural connectedness that researchers need to further explore the role of culture in enhancing resiliency and well-being among FN youth in Canada. 2015 APA, all rights reserved

Evidence shows that living in small scale homelike Special Care Units (SCU) has positive effects on behavioural and psychological symptoms of patients with dementia. Effects on cognitive functioning in relation to care facilities, however, are scarcely investigated. The purpose of this study is to gain more insight into the effects of living in small scale homelike Special Care Units, compared to regular SCU's, on the course of cognitive functioning in dementia. A group of 67 patients with dementia who moved from a regular SCU to a small scale homelike SCU and a group of 48 patients with dementia who stayed in a regular SCU participated in the study. Cognitive and behavioural functioning was assessed by means of a neuropsychological test battery and observation scales one month before (baseline), as well as 3 (post) and 6 months (follow-up) after relocation. Comparing the post and follow-up measurement with the baseline measurement, no significant differences on separate measures of cognitive functioning between both groups were found. Additional analyses, however, on 'domain clusters' revealed that global cognitive functioning of the small scale homelike SCU group showed significantly less cognitive decline three months after the transfer (p Effect sizes (95% CI) show a tendency for better aspects of cognition in favour of the homelike small scaled SCU group, i.e., visual memory, picture recognition, cognitive decline as observed by representatives and the clustered domains episodic memory and global cognitive functioning. While there is no significant longitudinal effect on the progression of cognitive decline comparing small scaled homelike SCU's with regular SCU's for patients with dementia, analyses on the domain clusters and effect sizes cautiously suggest differences in favour of the small scaled homelike SCU for different aspects of cognition.

The manufacturing of fermented sausages is subject to natural contamination processes that can potentially carry foodborne pathogens along the process chain and result in contamination of the final product. The aim of this study was to evaluate the occurrence of Salmonella spp. and Listeria monocytogenes at different sampling points during the manufacturing process of fuet, a type of traditional fermented sausage, at 10 small-scale Spanish factories. The presence of both pathogens was studied in the raw materials (19 casings and 19 meat batters), the final products (19 fermented sausages), and the factory equipment (12 mincing, 12 mixing, and 19 stuffing machines, 19 cutting tables, 11 knives, and 12 cold rooms) by using classical microbiological techniques and real-time PCR. Salmonella was not detected in the equipment analyzed or in the final products, but it was detected in the raw materials (23.7% of samples). L. monocytogenes showed higher incidence than Salmonella and was detected in the equipment (11.8% of samples), the raw materials (28.9%), and the final products (15.8%), confirming its ubiquity throughout the manufacturing process of fermented sausages. Five factories were further investigated to study the changes in the distribution of pathogens in the fuet production process over a period of either 2 or 3 years. There was considerable variation in the incidence of both pathogens at different sampling periods, and there was no relation between seasonal variations or geographic location of the factories.

Based on the social construction perspective, this research aims to investigate how traditional cultural values may affect the way individuals interpret and negotiate with their minority sexual identity. Using an online survey questionnaire with a student sample of 149 Chinese lesbian, gay, and bisexual (LGB) individuals, 2 elements of traditional Chinese culture were found to be associated with negative LGB identity among Chinese LGB students-namely, perceived parental attitudes toward marriage and participants' endorsements of filial piety values. In addition, the endorsement of filial piety moderated the relation between perceived parental attitudes toward marriage and LGB identity, such that the effect of parental attitude on LGB identity was only present among LGBs of high filial piety. This study suggests the importance of cultural values in shaping the way LGB individuals perceive their sexual identities.

The Impact of Traditional Culture on Farmers’ Moral Hazard Behavior in Crop Production: Evidence from China

Liguo Zhang

2016-07-01

Full Text Available To obtain higher yields, farmers may excessively use pesticides when they grow crops (like rice, vegetables, or fruit, causing moral hazard behavior. This paper examines how Chinese farmers’ moral hazard behavior in crop production is influenced by their traditional culture. A semi-parametric logistic model is used to investigate the impact of Chinese traditional culture on farmers’ moral hazard behavior. The results reveal that Chinese traditional culture has a positive effect on ameliorating the farmers’ excessive use of pesticides in crop production, which leads to a moral hazard in agro-product safety. Specifically, when we control for extraneous variables, the probability of moral hazard decreases by 15% if farmers consider their traditional culture in their production decisions. Moreover, the probability of moral hazard decreases by 17% if farmers consider the traditional culture as a powerful restraint regarding the use of pesticides. Our analysis provides some supportive evidence on the effect of Chinese traditional culture on mitigating farmers’ excessive use of pesticides.

Cultural Attitudes as WTP Determinants: A Revised Cultural Worldview Scale

Andy S. Choi

2016-06-01

Full Text Available There has been little attention paid to the systematic measurement issue of general attitudes toward human-culture relationships. This paper applied the Cultural Worldview (CW scale that was developed by Choi et al. in 2007 (published in the Journal of Cultural Economics, and investigated its dimensionality and relationship with willingness to pay (WTP for cultural heritage protection through a sequential integration between latent variables and valuation models. A case study of 997 Korean respondents was employed to examine conservation values of cultural heritage sites using discrete choice models. Confirmatory factor analyses demonstrated that this scale can be used either as a single second-order factor or four correlated factors. A more parsimonious version of the CW scale with twelve items is endorsed in this paper and the results also confirm that it is valid for use with non-Western nations. The findings support a significant attitude–WTP relationship; there was a significant role of the CW scale that reveals unobserved factors in valuation models.

Untangling cultural inheritance: language diversity and long-house architecture on the Pacific northwest coast

Science.gov (United States)

Jordan, Peter; O'Neill, Sean

2010-01-01

Many recent studies of cultural inheritance have focused on small-scale craft traditions practised by single individuals, which do not require coordinated participation by larger social collectives. In this paper, we address this gap in the cultural transmission literature by investigating diversity in the vernacular architecture of the Pacific northwest coast, where communities of hunter–fisher–gatherers constructed immense wooden long-houses at their main winter villages. Quantitative analyses of long-house styles along the coastline draw on a range of models and methods from the biological sciences and are employed to test hypotheses relating to basic patterns of macro-scale cultural diversification, and the degree to which the transmission of housing traits has been constrained by the region's numerous linguistic boundaries. The results indicate relatively strong branching patterns of cultural inheritance and also close associations between regional language history and housing styles, pointing to the potentially crucial role played by language boundaries in structuring large-scale patterns of cultural diversification, especially in relation to ‘collective’ cultural traditions like housing that require substantial inputs of coordinated labour.

Small scale structure on cosmic strings

International Nuclear Information System (INIS)

Albrecht, A.

1989-01-01

I discuss our current understanding of cosmic string evolution, and focus on the question of small scale structure on strings, where most of the disagreements lie. I present a physical picture designed to put the role of the small scale structure into more intuitive terms. In this picture one can see how the small scale structure can feed back in a major way on the overall scaling solution. I also argue that it is easy for small scale numerical errors to feed back in just such a way. The intuitive discussion presented here may form the basis for an analytic treatment of the small structure, which I argue in any case would be extremely valuable in filling the gaps in our resent understanding of cosmic string evolution. 24 refs., 8 figs

Complexities and uncertainties in transitioning small-scale coral reef fisheries

2016-05-01

Full Text Available Coral reef fisheries support the development of local and national economies and are the basis of important cultural practices and worldviews. Transitioning economies, human development and environmental stress can harm this livelihood. Here we focus on a transitioning social-ecological system as case study (Moorea, French Polynesia. We review fishing practices and three decades of effort and landing estimates with the broader goal of informing management. Fishery activities in Moorea are quite challenging to quantify because of the diversity of gears used, the lack of centralized access points or markets, the high participation rates of the population in the fishery, and the overlapping cultural and economic motivations to catch fish. Compounding this challenging diversity, we lack a basic understanding of the complex interplay between the cultural, subsistence, and commercial use of Moorea's reefs. In Moorea, we found an order of magnitude gap between estimates of fishery yield produced by catch monitoring methods (~2 t km-2 year-1 and estimates produced using consumption or participatory socioeconomic consumer surveys (~24 t km-2 year-1. Several lines of evidence suggest reef resources may be overexploited and stakeholders have a diversity of opinions as to whether trends in the stocks are a cause for concern. The reefs, however, remain ecologically resilient. The relative health of the reef is striking given the socio-economic context. Moorea has a relatively high population density, a modern economic system linked into global flows of trade and travel, and the fishery has little remaining traditional or customary management. Other islands in the Pacific that continue to develop economically may have small-scale fisheries that increasingly resemble Moorea. Therefore, understanding Moorea's reef fisheries may provide insight into their future.

Full Text Available The article discusses the memory of the costumes and the way people record and interpret their relations with them. This is on the assumption that we put ourselves at all, and for that reason, too, the popular costumes reveal the political place of each subject on the Festa de São Benedito in Congada de Ilhabela - manifestation of African descent culture chosen to treated in this text. This study aimed to understand the role of costume in the composition of the cultural identity of black ethnic-racial group of Ilhabela, to point out how a seemingly simple costume can reveal so many meanings for the group in question. The Congada de Ilhabela is the devotion of a population to a saint; holy and black people who resisted the many prejudices and deep social and economic transformations. Therefore, the expression of that culture and tradition invented by means of a negotiated identity will be discussed. Regarding the costume, the study will be based on material culture and participant observation conducted with this population between the years 1995 to 2002.

Traditions and Alcohol Use: A Mixed-Methods Analysis

Castro, Felipe González; Coe, Kathryn

2011-01-01

An integrative mixed-methods analysis examined traditional beliefs as associated with beliefs about self-care during pregnancy and with alcohol abstinence among young adult women from two rural U.S.–Mexico border communities. Quantitative (measured scale) variables and qualitative thematic variables generated from open-ended responses served as within-time predictors of these health-related outcomes. A weaker belief that life is better in big cities was associated with stronger self-care beliefs during pregnancy. Also, a weaker belief that small towns offer tranquil environments was associated with total abstinence from alcohol. Regarding the Hispanic Paradox, these results suggest that a critical appreciation of cultural traditions can be protective, as this avoids stereotypical or idyllic views of urban or rural lifeways, and promotes self-protective beliefs and behaviors.

Integrating Traditional Ecological Knowledge and Ecological Science: a Question of Scale

Full Text Available The benefits and challenges of integrating traditional ecological knowledge and scientific knowledge have led to extensive discussions over the past decades, but much work is still needed to facilitate the articulation and co-application of these two types of knowledge. Through two case studies, we examined the integration of traditional ecological knowledge and scientific knowledge by emphasizing their complementarity across spatial and temporal scales. We expected that combining Inuit traditional ecological knowledge and scientific knowledge would expand the spatial and temporal scales of currently documented knowledge on the arctic fox (Vulpes lagopus and the greater snow goose (Chen caerulescens atlantica, two important tundra species. Using participatory approaches in Mittimatalik (also known as Pond Inlet, Nunavut, Canada, we documented traditional ecological knowledge about these species and found that, in fact, it did expand the spatial and temporal scales of current scientific knowledge for local arctic fox ecology. However, the benefits were not as apparent for snow goose ecology, probably because of the similar spatial and temporal observational scales of the two types of knowledge for this species. Comparing sources of knowledge at similar scales allowed us to gain confidence in our conclusions and to identify areas of disagreement that should be studied further. Emphasizing complementarities across scales was more powerful for generating new insights and hypotheses. We conclude that determining the scales of the observations that form the basis for traditional ecological knowledge and scientific knowledge represents a critical step when evaluating the benefits of integrating these two types of knowledge. This is also critical when examining the congruence or contrast between the two types of knowledge for a given subject.

To investigate whether and how the presence of Confucian cultural norms influences the sexual behaviors of adolescents and young adults in three Asian cities experiencing different levels of economic development. Data for this article were drawn from the international cross-sectional survey on sexual and reproductive health of adolescents and young adults aged 15-24 years in three Asian cities (Hanoi, Shanghai, and Taipei), conducted in 2006. The original sample consisted of a representative group of 17,016 adolescents; while in this study, 16,554 never-married adolescents were included in the analysis. Both face-to-face interview and computer-assisted self-interview approaches were adopted in the survey. Exposure to family concepts, self-cultivation values, gender role concepts, and sexual values were the main measures of traditional Confucian cultural influence. Sexual and intimate behaviors were the main outcome measures, and multi-Cox regression models were used to assess the association between traditional cultural concepts and values and sexual behavior after adjusting for potentially confounding factors. Data were analyzed with SAS software 9.1. The traditional Confucian cultural norms were not weakening evenly, with more entrenchment in Hanoi than in Shanghai and Taipei. Prevalence of sexual coitus among adolescent and young adults was lowest in Hanoi and highest in Taipei, while similar profiles of other intimate behaviors were displayed in the three cities. Associations between respondents' sexual behavior and their cultural concepts and values differed by city. In Hanoi, for all four cultural measures, respondents with more traditional views were less likely to engage in sexual activity. This was also true in Shanghai and Taipei with respect to traditional sexual values and self-cultivation values. However, there was an inverse relationship between sexual behavior and traditional family concepts and gender roles in Shanghai and Taipei; those with more

The types of goods that were brought was related to the shapes of the containers, demonstrate the type of interactions between the carrier and the goods. The Traditional Carrying Tools made of cloth have the flexibility in terms of being the containers of the carried goods. Selendang is used to carry goods, including the bamboo/ rattan containers and to carry babies. It can be used rumpled and straightened depends on the technical needs of carrying tools preferred by the user. In contemporary culture, the form and design of carrying tools more less construct by fashion and trends besides those practical used. Some product are being 'classic', some other are being 'fad'. Both products, traditional and contemporary have their own style, uniqueness, and own context. Analyzing both in design point of view is important as evaluation process, to finding new problems that will be starting point to create new products. Indonesia is well known for its abundant richness in traditions, which include the culture, the art, and the traditional products. Such treasure of traditions can inspire the development and invention of various kinds of artwork and current products.

Assessing the ecosystem-level consequences of a small-scale artisanal kelp fishery within the context of climate-change.

Coastal communities worldwide rely on small-scale artisanal fisheries as a means of increasing food security and alleviating poverty. Even small-scale fishing activities, however, are prone to resource depletion and environmental degradation, which can erode livelihoods in the long run. Thus, there is a pressing need to identify viable and resilient artisanal fisheries, and generate knowledge to support management within the context of a rapidly changing climate. We examined the ecosystem-level consequences of an artisanal kelp fishery (Macrocystis pyrifera), finding small-scale harvest of this highly productive species poses minimal impacts on kelp recovery rates, survival, and biomass dynamics, and abundances of associated commercial and culturally important fish species. These results suggest that small-scale harvest poses minimal trade-offs for the other economic benefits provided by these ecosystems, and their inherent, spiritual, and cultural value to humans. However, we detected a negative impact of warmer seawater temperatures on kelp recovery rates following harvest, indicating that the viability of harvest, even at small scales, may be threatened by future increases in global ocean temperature. This suggests that negative impacts of artisanal fisheries may be more likely to arise in the context of a warming climate, further highlighting the widespread effects of global climate change on coastal fisheries and livelihoods. © 2016 by the Ecological Society of America.

Cultural primatology (i.e., the study of behavioral traditions in nonhuman primates as a window into the evolution of human cultural capacities) was founded in Japan by Kinji Imanishi in the early 1950s. This relatively new research area straddles different disciplines and now benefits from collaborations between Japanese and Western primatologists. In this paper, we return to the cradle of cultural primatology by revisiting our original articles on behavioral innovations and traditions in Japanese macaques. For the past 35 years, our international team of biologists, psychologists and anthropologists from Japan, France, Sri Lanka, the USA and Canada, has been taking an integrative approach to addressing the influence of environmental, sociodemographic, developmental, cognitive and behavioral constraints on the appearance, diffusion, and maintenance of behavioral traditions in Macaca fuscata across various domains; namely, feeding innovation, tool use, object play, and non-conceptive sex.

Energy transfers in large-scale and small-scale dynamos

We present the energy transfers, mainly energy fluxes and shell-to-shell energy transfers in small-scale dynamo (SSD) and large-scale dynamo (LSD) using numerical simulations of MHD turbulence for Pm = 20 (SSD) and for Pm = 0.2 on 10243 grid. For SSD, we demonstrate that the magnetic energy growth is caused by nonlocal energy transfers from the large-scale or forcing-scale velocity field to small-scale magnetic field. The peak of these energy transfers move towards lower wavenumbers as dynamo evolves, which is the reason for the growth of the magnetic fields at the large scales. The energy transfers U2U (velocity to velocity) and B2B (magnetic to magnetic) are forward and local. For LSD, we show that the magnetic energy growth takes place via energy transfers from large-scale velocity field to large-scale magnetic field. We observe forward U2U and B2B energy flux, similar to SSD.

The Phenomenology of Small-Scale Turbulence

I have sometimes thought that what makes a man's work classic is often just this multiplicity [of interpretations], which invites and at the same time resists our craving for a clear understanding. Wright (1982, p. 34), on Wittgenstein's philosophy Small-scale turbulence has been an area of especially active research in the recent past, and several useful research directions have been pursued. Here, we selectively review this work. The emphasis is on scaling phenomenology and kinematics of small-scale structure. After providing a brief introduction to the classical notions of universality due to Kolmogorov and others, we survey the existing work on intermittency, refined similarity hypotheses, anomalous scaling exponents, derivative statistics, intermittency models, and the structure and kinematics of small-scale structure - the latter aspect coming largely from the direct numerical simulation of homogeneous turbulence in a periodic box.

Microfabricated modular scale-down device for regenerative medicine process development.

Full Text Available The capacity of milli and micro litre bioreactors to accelerate process development has been successfully demonstrated in traditional biotechnology. However, for regenerative medicine present smaller scale culture methods cannot cope with the wide range of processing variables that need to be evaluated. Existing microfabricated culture devices, which could test different culture variables with a minimum amount of resources (e.g. expensive culture medium, are typically not designed with process development in mind. We present a novel, autoclavable, and microfabricated scale-down device designed for regenerative medicine process development. The microfabricated device contains a re-sealable culture chamber that facilitates use of standard culture protocols, creating a link with traditional small-scale culture devices for validation and scale-up studies. Further, the modular design can easily accommodate investigation of different culture substrate/extra-cellular matrix combinations. Inactivated mouse embryonic fibroblasts (iMEF and human embryonic stem cell (hESC colonies were successfully seeded on gelatine-coated tissue culture polystyrene (TC-PS using standard static seeding protocols. The microfluidic chip included in the device offers precise and accurate control over the culture medium flow rate and resulting shear stresses in the device. Cells were cultured for two days with media perfused at 300 µl.h(-1 resulting in a modelled shear stress of 1.1×10(-4 Pa. Following perfusion, hESC colonies stained positively for different pluripotency markers and retained an undifferentiated morphology. An image processing algorithm was developed which permits quantification of co-cultured colony-forming cells from phase contrast microscope images. hESC colony sizes were quantified against the background of the feeder cells (iMEF in less than 45 seconds for high-resolution images, which will permit real-time monitoring of culture progress in future

In a culturally diverse society, youth learn about multiple cultures from a variety of sources, yet the existing assessment of cultural socialization has been limited to parents' efforts to teach youth about their heritage culture. The current study adapted and extended an existing cultural socialization measure (Umaña-Taylor & Fine, 2004) to assess four types of socialization practices encountered specifically during adolescence: cultural socialization by families and peers toward both one's heritage culture and the mainstream culture. In a pilot study, we developed the cultural socialization scale based on retrospective reports from 208 young adults, maximizing young adults' ability to reason and reflect their adolescent experiences with various socialization practices. In the primary study, we examined the psychometric properties of the scale using reports from 252 adolescents. Cultural socialization occurred from both socialization agents toward both cultures. Our cultural socialization scale demonstrated stable factor structures and high reliabilities. We observed strong factorial invariance across the four subscales (six items). MIMIC models also demonstrated invariance for each subscale across adolescents' demographic characteristics (i.e., gender, race/ethnicity, nativity, SES, language of assessment). The implications of the cultural socialization scale are discussed. PMID:25961139

A biological rationale for musical scales.

Kamraan Z Gill

Full Text Available Scales are collections of tones that divide octaves into specific intervals used to create music. Since humans can distinguish about 240 different pitches over an octave in the mid-range of hearing, in principle a very large number of tone combinations could have been used for this purpose. Nonetheless, compositions in Western classical, folk and popular music as well as in many other musical traditions are based on a relatively small number of scales that typically comprise only five to seven tones. Why humans employ only a few of the enormous number of possible tone combinations to create music is not known. Here we show that the component intervals of the most widely used scales throughout history and across cultures are those with the greatest overall spectral similarity to a harmonic series. These findings suggest that humans prefer tone combinations that reflect the spectral characteristics of conspecific vocalizations. The analysis also highlights the spectral similarity among the scales used by different cultures.

Western Balkan countries (WBCs) have a long-standing culinary tradition. The promotion of traditional foods may be a tool for coping with modernisation trends in such transition economies. This paper explores consumer preferences toward food in this region, focusing on a traditional fresh cow cheese locally called 'Mladi Sir'. This product was quoted in all the preliminary focus groups as a common traditional product present in the six WBCs studied: Bosnia-Herzegovina, Croatia, Macedonia, Montenegro, Serbia and Slovenia. After a literature review investigating the concept of traditional food in WBCs and the implementation of focus groups, a survey including a conjoint analysis on preferences for fresh cow cheese was carried out in 2011 to collect data from 1200 respondents. Four clusters of consumers were identified: one focused more on the local origin; one oriented more toward the scale of production (on-farm and small dairy); the third favouring low prices and the fourth preferring high prices and industrial products. Policy makers and the supply chain could take these differences in consumer preferences regarding traditional food products into account in order to develop specific strategies. © 2013 Society of Chemical Industry.

2012-10-01

The purpose of this study is to explore the cultural definitions of financial abuse from the perspective of 124 elderly Korean immigrants and to examine the role of traditional cultural values in their definitions by using a mixed methods approach. The qualitative analysis generated four themes relevant to definition of financial abuse. A binary logistic regression indicated that those with stronger cultural adherence to traditional values had higher odds of providing culture-based definitions of financial abuse. Education is needed for health professionals, social service providers, and adult protective workers to increase their understanding of culture-specific experiences of financial abuse among ethnic minority elders.

Social welfare as small-scale help: evolutionary psychology and the deservingness heuristic.

Science.gov (United States)

Petersen, Michael Bang

2012-01-01

Public opinion concerning social welfare is largely driven by perceptions of recipient deservingness. Extant research has argued that this heuristic is learned from a variety of cultural, institutional, and ideological sources. The present article provides evidence supporting a different view: that the deservingness heuristic is rooted in psychological categories that evolved over the course of human evolution to regulate small-scale exchanges of help. To test predictions made on the basis of this view, a method designed to measure social categorization is embedded in nationally representative surveys conducted in different countries. Across the national- and individual-level differences that extant research has used to explain the heuristic, people categorize welfare recipients on the basis of whether they are lazy or unlucky. This mode of categorization furthermore induces people to think about large-scale welfare politics as its presumed ancestral equivalent: small-scale help giving. The general implications for research on heuristics are discussed.

Identification of small-scale discontinuities based on dip-oriented gradient energy entropy coherence estimation

Locating small-scale discontinuities is one of the most challenging geophysical tasks; these subtle geological features are significant since they are often associated with subsurface petroleum traps. Subtle faults, fractures, unconformities, reef textures, channel boundaries, thin-bed boundaries and other structural and stratigraphic discontinuities have subtle geological edges which may provide lateral variation in seismic expression. Among the different geophysical techniques available, 3D seismic discontinuity attributes are particularly useful for highlighting discontinuities in the seismic data. Traditional seismic discontinuity attributes are sensitive to noise and are not very appropriate for detecting small-scale discontinuities. Thus, we present a dip-oriented gradient energy entropy (DOGEE) coherence estimation method to detect subtle faults and structural features. The DOGEE coherence estimation method uses the gradient structure tensor (GST) algorithm to obtain local dip information and construct a gradient correlation matrix to calculate gradient energy entropy. The proposed DOGEE coherence estimation method is robust to noise, and also improves the clarity of fault edges. It is effective for small-scale discontinuity characterisation and interpretation.

Context-Related Melodies in Oral Culture: An Attempt to Describe Words-and-Music Relationships in Local Singing Tradition

2009-08-01

Full Text Available In oral folk song traditions we often find many lyrics, but not nearly as many melodies. The terms “polyfunctionalism”, “group melodies” or “general melodies” have been used by Estonian researches to indicate the phenomenon that many lyrics were sung to only one, or a small handful, of tunes. The scarcity of melodies is supposed to be one of several related phenomena characteristic to an oral, text-centred singing culture.In this article the Estonian folk song tradition will be analysed against a quantity of melodies and their usage in the following aspects: word-and-melody relationships and context-and-melody relationships in Karksi parish (south Estonia; a singer; and native musical terms and the process of singing and (recreation.

Type II diabetes mellitus is currently the leading cause of death in Mexico. Oaxaca is one of the poorest states in Mexico with the largest concentration of indigenous people in the country. Despite the alarming increase of diabetes rates in this region, little is known about the indigenous populations' cultural understandings and related practices for this chronic disease. This study examined diabetes cultural beliefs and traditional medicine use among a sample of 158 adults with and without diabetes in Oaxaca, Mexico. Individuals with and without diabetes did not differ in their traditional culture beliefs regarding diabetes in this study. Younger age (OR = 1.04) and stronger beliefs in punitive and mystical retribution (OR = 5.42) regarding diabetes causality increased the likelihood of using traditional medicine (p diabetes prevention and management efforts in the region.

Development of small-scale peat production; Pienturvetuotannon kehittaeminen

Energy Technology Data Exchange (ETDEWEB)

Erkkilae, A.; Kallio, E. [VTT Energy, Jyvaeskylae (Finland)

1997-12-01

The aim of the project is to develop production conditions, methods and technology of small-scale peat production to such a level that the productivity is improved and competitivity maintained. The aim in 1996 was to survey the present status of small-scale peat production, and research and development needs and to prepare a development plan for small-scale peat production for a continued project in 1997 and for the longer term. A questionnaire was sent to producers by mail, and its results were completed by phone interviews. Response was obtained from 164 producers, i.e. from about 75 - 85 % of small-scale peat producers. The quantity of energy peat produced by these amounted to 3.3 TWh and that of other peat to 265 000 m{sup 3}. The total production of energy peat (large- scale producers Vapo Oy and Turveruukki Oy included) amounted to 25.0 TWh in 1996 in Finland, of which 91 % (22.8 TWh) was milled peat and 9 % (2.2 TWh) of sod peat. The total production of peat other than energy peat amounted to 1.4 million m{sup 3}. The proportion of small-scale peat production was 13 % of energy peat, 11 % of milled peat and 38 % of sod peat. The proportion of small-scale producers was 18 % of other peat production. The results deviate clearly from those obtained in a study of small-scale production in the 1980s. The amount of small-scale production is clearly larger than generally assessed. Small-scale production focuses more on milled peat than on sod peat. The work will be continued in 1997. Based on development needs appeared in the questionnaire, the aim is to reduce environmental impacts and runoff effluents from small- scale production, to increase the efficiency of peat deliveries and to reduce peat production costs by improving the service value of machines by increasing co-operative use.

2010-01-01

The Department of Defense (000) has successfully applied a number of methods for cultural familiarization training ranging from stand-up classroom training, to face-to-face live role-play, to so-called smart-cards. Recent interest has turned to the use of single and mUlti-player gaming technologies to augment these traditional methods of cultural familiarization. One such system, termed CulturePad, has been designed as a game-based role-play environment suitable for use in training and experimentation involving cultural roleplay scenarios. This paper describes the initial CulturePad effort focused on a literature review regarding the use of role-play for cultural training and a feasibility assessment of using a game-mediated environment for role-play. A small-scale pilot involving cultural experts was conducted to collect qualitative behavioral data comparing live role-play to game-mediated role-play in a multiplayer gaming engine.

Full Text Available Buffalo husbandry is an important source of income for a number of small-scale producers in Romania that is why an assessment of its products quality is much needed for improvement and evaluation of their vulnerability to international competition. In order to ascertain possible developments in the buffalo dairy sector and to broadly identify areas of intervention that favor small-scale dairy producers, the study examined the potential to improve buffalo milk production by evaluating its authenticity and hygienic quality. The methods used involved the molecular testing (PCR-technique for identifying cow, sheep or goat DNA in the dairy products samples collected from the small-scale producers market. The hygienic quality of these samples was determined through classical microbiology methods, highly developed techniques (Trek System and PCR for bacterial species confirmation. The results showed that a high percent (65%, from the products found were adulterated with other species milk, mostly cow milk. The most commonly falsified buffalo dairy products were the cheese and the traditional product telemea. The prevalence of the bacterial species identified belonged to Listeria innocua and Listeria welshmeri. The conclusion of this study is the need of a durable development system in this particular dairy chain to improve and assure the authenticity and quality of the small-scale producers products and their reliability for the consumers.

Mariyappan, J.; Bhardwaj, N.; De Coninck, H.; Van der Linden, N.

2005-07-01

Small-scale renewable energy and energy efficiency projects that fit the development needs of many developing countries, can potentially be supported via the Clean Development Mechanism (CDM), one of the Kyoto Protocol's flexible mechanisms for tackling climate change. However, there is concern that due to high transaction costs, as well as many existing barriers, very few investments will be made in small-scale projects, which are often the most suitable development option in countries such as India. In view of this, the 'bundling' together of appropriate small-scale projects on a regional basis has been proposed as a way in which funding can be leveraged from international sources and transaction costs reduced. IT Power, IT Power India and the Energy research Centre of the Netherlands (ECN) are carrying out a 2-year project to establish the capacity within India to enable individual small scale projects to be bundled as a single CDM project. Overall objectives are to develop the necessary institutional capabilities to formulate and implement small scale CDM projects in India; to provide a guide on how to bundle small scale projects under the CDM in developing countries; and to raise the awareness of the potential for investment in small scale energy projects which can gain funding through the CDM

An experiment was carried out on the bachelor's degree course in nursing with two new clinical placement concepts: workplace learning and the dedicated education centre. The aim was to establish a learning culture that creates a sufficiently high learning performance for students. The objectives of this study are threefold: (1) to look for a difference in the "learning culture" and "learning performance" in traditional clinical placement departments and the new clinical placement concepts, the "dedicated education centre" and "workplace learning"; (2) to assess factors influencing the learning culture and learning performance; and (3) to investigate whether there is a link between the learning culture and the learning performance. A non-randomised control study was carried out. The experimental group consisted of 33 final-year nursing undergraduates who were following clinical placements at dedicated education centres and 70 nursing undergraduates who undertook workplace learning. The control group consisted of 106 students who followed a traditional clinical placement. The "learning culture" outcome was measured using the Clinical Learning Environment, Supervision and Nurse Teacher scale. The "learning performance" outcome consisting of three competencies was measured using the Nursing Competence Questionnaire. The traditional clinical placement concept achieved the highest score for learning culture (plearning performance of which the dedicated education centres achieved the highest scores. The 3 clinical placement concepts showed marked differences in learning performance for the "assessment" competency (plearning can be seen as complementary clinical placement concepts. The organisation of clinical placements under the dedicated education centre concept and workplace learning is recommended for final-year undergraduate nursing students.

2012-05-01

Technology Management, Inc. (TMI) of Cleveland, Ohio, has completed the project entitled Small Scale SOFC Demonstration using Bio-based and Fossil Fuels. Under this program, two 1-kW systems were engineered as technology demonstrators of an advanced technology that can operate on either traditional hydrocarbon fuels or renewable biofuels. The systems were demonstrated at Patterson's Fruit Farm of Chesterland, OH and were open to the public during the first quarter of 2012. As a result of the demonstration, TMI received quantitative feedback on operation of the systems as well as qualitative assessments from customers. Based on the test results, TMI believes that > 30% net electrical efficiency at 1 kW on both traditional and renewable fuels with a reasonable entry price is obtainable. The demonstration and analysis provide the confidence that a 1 kW entry-level system offers a viable value proposition, but additional modifications are warranted to reduce sound and increase reliability before full commercial acceptance.

The cultural and community-level acceptance of antiretroviral therapy (ART) among traditional healers in Eastern Cape, South Africa.

Shuster, Justin M; Sterk, Claire E; Frew, Paula M; del Rio, Carlos

2009-02-01

The HIV/AIDS epidemic has profoundly impacted South Africa's healthcare system, greatly hampering its ability to scale-up the provision of antiretroviral therapy (ART). While one way to provide comprehensive care and prevention in sub-Saharan African countries has been through collaboration with traditional healers, long-term support specifically for ART has been low within this population. An exploratory, qualitative research project was conducted among 25 self-identified traditional healers between June and August of 2006 in the Lukhanji District of South Africa. By obtaining the opinions of traditional healers currently interested in biomedical approaches to HIV/AIDS care and prevention, this formative investigation identified a range of motivational factors that were believed to promote a deeper acceptance of and support for ART. These factors included cultural consistencies between traditional and biomedical medicine, education, as well as legal and financial incentives to collaborate. Through an incorporation of these factors into future HIV/AIDS treatment programs, South Africa and other sub-Saharan countries may dramatically strengthen their ability to provide ART in resource-poor settings.

Technologies for small scale wood-fueled combined heat and power systems

Energy Technology Data Exchange (ETDEWEB)

Houmann Jakobsen, H.; Houmoeller, S.; Thaaning Pedersen, L.

1998-01-01

The aim of this study is to describe and compare different technologies for small cogeneration systems (up to 2-3 MW{sub e}), based on wood as fuel. For decentralized cogeneration, i.e. for recovering energy from saw mill wood wastes or heat supply for small villages, it is vital to know the advantages and disadvantages of the different technologies. Also, for the decision-makers it is of importance to know the price levels of the different technologies. A typical obstacle for small wood cogeneration systems is the installation costs. The specific price (per kW) is usually higher than for larger plants or plants using fossil fuels. For a saw mill choosing between cogeneration and simple heat production, however, the larger installation costs are counter weighed by the sale of electricity, while the fuel consumption is the same. Whether it is profitable or not to invest in cogeneration is often hard to decide. For many years small wood cogeneration systems have been too expensive, leading to the construction of only heat producing systems due to too high price levels of small steam turbines. In recent years a great deal of effort has been put into research and developing of new technologies to replace this traditional steam turbine. Among these are: Steam engines; Stirling engines; Indirectly fired gas turbines; Pressurized down draft combustion. Along with the small scale traditional steam turbines, these technologies will be evaluated in this study. When some or all these technologies are fully developed and commercial, a strong means of reducing the strain on the environment and the greenhouse effect will be available, as the total efficiency is high (up to 90%) and wood is an energy source in balance with nature.

2015-02-01

In Mexico, small-scale dairy systems (SSDS) represent over 78 % of dairy farms and contribute with 37 % of national milk production; however, they face high feeding costs. The objective of this study was to assess the performance of SSDS during the dry season in terms of milk yields, milk composition and feeding costs under traditional feeding strategies, to identify areas of opportunity for improving their profitability. The information was collected from 22 SSDS every month during dry season. Feeds were classified in quality forages (QF), supplements (SU) and straws (ST). Two factors were identified: factor 1-a positive relationship among QF, SU, milk yield and ration cost and factor 2-represented straw usage. Four feeding strategies were identified: (1) low-cost feeding strategy; (2) home-grown feeding strategy; (3) high-cost feeding strategy; and (4) straw-based feeding strategy. There were differences (P  0.05) differences among feeding strategies for fat and protein contents in milk. It is concluded that to improve performance and profitability and enhance sustainability in SSDS, farmers should base feeding strategies on home-grown quality forages, as it was the case in group 2 which showed lower feeding cost and better milk yield. It is also recommended to increase the inclusion of quality forages like grazing pastures and maize silages during the dry season and to avoid the inclusion of straws.

Trickle-bed root culture bioreactor design and scale-up: growth, fluid-dynamics, and oxygen mass transfer.

Science.gov (United States)

Ramakrishnan, Divakar; Curtis, Wayne R

2004-10-20

Trickle-bed root culture reactors are shown to achieve tissue concentrations as high as 36 g DW/L (752 g FW/L) at a scale of 14 L. Root growth rate in a 1.6-L reactor configuration with improved operational conditions is shown to be indistinguishable from the laboratory-scale benchmark, the shaker flask (mu=0.33 day(-1)). These results demonstrate that trickle-bed reactor systems can sustain tissue concentrations, growth rates and volumetric biomass productivities substantially higher than other reported bioreactor configurations. Mass transfer and fluid dynamics are characterized in trickle-bed root reactors to identify appropriate operating conditions and scale-up criteria. Root tissue respiration goes through a minimum with increasing liquid flow, which is qualitatively consistent with traditional trickle-bed performance. However, liquid hold-up is much higher than traditional trickle-beds and alternative correlations based on liquid hold-up per unit tissue mass are required to account for large changes in biomass volume fraction. Bioreactor characterization is sufficient to carry out preliminary design calculations that indicate scale-up feasibility to at least 10,000 liters.

Small-scale household biogas digesters

There are a number of advantages to small-scale biogas production on farms, including savings on firewood or fossil fuels and reductions in odour and greenhouse gas emissions. For these reasons, governments and development aid agencies have supported the installation of biogas digesters. However......, biogas digesters are often poorly managed and there is a lack of proper distribution systems for biogas. This results in methane being released inadvertently through leaks in digesters and tubing, and intentionally when production exceeds demand. As methane has a global warming potential 25 times greater......% of the produced biogas is released, depending on the type of fuel that has been replaced. The limited information available as regards methane leaking from small-scale biogas digesters in developing countries indicates that emissions may be as high as 40%. With the best estimates of global numbers of small...

We explore how different ‘logics of protection’ have served to legitimize Danish military participation in large-scale US-led interventions. Based on this analysis, we discuss...

Small-scale eruptive filaments on the quiet sun

International Nuclear Information System (INIS)

Hermans, L.M.; Martin, S.F.

1986-01-01

A study of a little known class of eruptive events on the quiet sun was conducted. All of 61 small-scale eruptive filamentary structures were identified in a systematic survey of 32 days of H alpha time-lapse films of the quiet sun acquired at Big Bear Solar Observatory. When fully developed, these structures have an average length of 15 arc seconds before eruption. They appear to be the small-scale analog of large-scale eruptive filaments observed against the disk. At the observed rate of 1.9 small-scale eruptive features per field of view per average 7.0 hour day, the rate of occurence of these events on the sun were estimated to be greater than 600 per 24 hour day.. The average duration of the eruptive phase was 26 minutes while the average lifetime from formation through eruption was 70 minutes. A majority of the small-scale filamentary sturctures were spatially related to cancelling magnetic features in line-of-sight photospheric magnetograms. Similar to large-scale filaments, the small-scale filamentary structures sometimes divided opposite polarity cancelling fragments but often had one or both ends terminating at a cancellation site. Their high numbers appear to reflect the much greater flux on the quiet sun. From their characteristics, evolution, and relationship to photospheric magnetic flux, it was concluded that the structures described are small-scale eruptive filaments and are a subset of all filaments

Full Text Available This research paper analyses the organizational culture of small enterprises and largeenterprises, and highlights the common elements and the main differences. The results of the studyshow significant differences in terms of organizational culture between the two types oforganizations. Employees working in small size enterprises are oriented towards innovation,whereas the ones working in large enterprises are more aware of social responsibility. In addition,small organizations are perceived to have a more supportive organizational culture than largeenterprises. Furthermore, the study reveals differences in management and leadership styles whenanalyzing the small and large enterprises. Considering the flatter organizational structure of smallenterprises, the managers have a personal relationship with the employees and they motivate thembetter and align their goals with the ones of the enterprise. In large organizations, the managersneed to have a tighter control, as more procedures have to be followed.

Probing the Small-scale Structure in Strongly Lensed Systems via Transdimensional Inference

Daylan, Tansu; Cyr-Racine, Francis-Yan; Diaz Rivero, Ana; Dvorkin, Cora; Finkbeiner, Douglas P.

2018-02-01

Strong lensing is a sensitive probe of the small-scale density fluctuations in the Universe. We implement a pipeline to model strongly lensed systems using probabilistic cataloging, which is a transdimensional, hierarchical, and Bayesian framework to sample from a metamodel (union of models with different dimensionality) consistent with observed photon count maps. Probabilistic cataloging allows one to robustly characterize modeling covariances within and across lens models with different numbers of subhalos. Unlike traditional cataloging of subhalos, it does not require model subhalos to improve the goodness of fit above the detection threshold. Instead, it allows the exploitation of all information contained in the photon count maps—for instance, when constraining the subhalo mass function. We further show that, by not including these small subhalos in the lens model, fixed-dimensional inference methods can significantly mismodel the data. Using a simulated Hubble Space Telescope data set, we show that the subhalo mass function can be probed even when many subhalos in the sample catalogs are individually below the detection threshold and would be absent in a traditional catalog. The implemented software, Probabilistic Cataloger (PCAT) is made publicly available at https://github.com/tdaylan/pcat.

Feelings about culture scales: development, factor structure, reliability, and validity.

Science.gov (United States)

Maffini, Cara S; Wong, Y Joel

2015-04-01

Although measures of cultural identity, values, and behavior exist in the multicultural psychological literature, there is currently no measure that explicitly assesses ethnic minority individuals' positive and negative affect toward culture. Therefore, we developed 2 new measures called the Feelings About Culture Scale--Ethnic Culture and Feelings About Culture Scale--Mainstream American Culture and tested their psychometric properties. In 6 studies, we piloted the measures, conducted factor analyses to clarify their factor structure, and examined reliability and validity. The factor structure revealed 2 dimensions reflecting positive and negative affect for each measure. Results provided evidence for convergent, discriminant, criterion-related, and incremental validity as well as the reliability of the scales. The Feelings About Culture Scales are the first known measures to examine both positive and negative affect toward an individual's ethnic culture and mainstream American culture. The focus on affect captures dimensions of psychological experiences that differ from cognitive and behavioral constructs often used to measure cultural orientation. These measures can serve as a valuable contribution to both research and counseling by providing insight into the nuanced affective experiences ethnic minority individuals have toward culture.

Grounding the nexus: Examining the integration of small-scale irrigators into a national food security programme in Burkina Faso

Directory of Open Access Journals (Sweden)

Brian Dowd-Uribe

2018-06-01

Full Text Available The water-food nexus literature examines the synergies and trade-offs of resource use but is dominated by large-scale analyses that do not sufficiently engage the local dimensions of resource management. The research presented here addresses this gap with a local-scale analysis of integrated water and food management in Burkina Faso. Specifically, we analyse the implementation of a national food security campaign (Opération Bondofa to boost maize production in a subbasin that exhibits two important trends in Africa: a large increase in small-scale irrigators and the decentralisation of water management. As surface water levels dropped in the region, entities at different scales asserted increased control over water allocation, exposing the contested nature of new decentralised institutions, and powerful actors’ preference for local control. These scalar power struggles intersected with a lack of knowledge of small-scale irrigators’ cultural practices to produce an implementation and water allocation schedule that did match small-scale irrigator needs, resulting in low initial enthusiasm for the project. Increased attention from national governments to strengthen decentralised water management committees and spur greater knowledge of, and engagement with, small-scale irrigators can result in improved programme design to better incorporate small-scale irrigators into national food security campaigns.

Small-scale fisheries bycatch jeopardizes endangered Pacific loggerhead turtles.

Directory of Open Access Journals (Sweden)

S Hoyt Peckham

2007-10-01

Full Text Available Although bycatch of industrial-scale fisheries can cause declines in migratory megafauna including seabirds, marine mammals, and sea turtles, the impacts of small-scale fisheries have been largely overlooked.

Although bycatch of industrial-scale fisheries can cause declines in migratory megafauna including seabirds, marine mammals, and sea turtles, the impacts of small-scale fisheries have been largely overlooked.

Liking of traditional cheese and consumer willingness to pay

Directory of Open Access Journals (Sweden)

Ada Braghieri

2014-03-01

Full Text Available We review herein the relevance of credence and sensory attributes for cheese liking as a basis for subsequent discussion on attributes related to traditional dairy products such as place of origin, process characteristics, etc. Several studies suggest that place of origin may have a positive impact on consumer evaluation. In addition, protected designation of origin labels generally affects consumers’ purchasing decisions, with a premium price paid for traditional products. Some of the main dimensions of traditional food products are: familiarity of the product, processing through traditional recipes, sensory properties and origins. However, different dimensions can be relevant for consumers of different countries. Southern European regions frequently tend to associate the concept of traditional with broad concepts such as heritage, culture or history; whereas central and northern European regions tend to focus mainly on practical issues such as convenience, health or appropriateness. Sensitivity to traditional cheese attributes may also vary according to different groups of consumers with older, more educated and wealthier subjects showing higher willingness to pay and acceptance levels. Given that sensory properties play a central role in product differentiation, we can conclude that information about credence attributes, if reliable, positively perceived and directed to sensitive groups of consumers, is able to affect consumer liking and willingness to pay for traditional cheese. Thus, it provides a further potential tool for product differentiation to small-scale traditional farms, where husbandry is often based on extensive rearing systems and production costs tend to be higher.

Rolling at small scales

The rolling process is widely used in the metal forming industry and has been so for many years. However, the process has attracted renewed interest as it recently has been adapted to very small scales where conventional plasticity theory cannot accurately predict the material response. It is well....... Metals are known to be stronger when large strain gradients appear over a few microns; hence, the forces involved in the rolling process are expected to increase relatively at these smaller scales.

To determine the prevalence of traditional food and physical activity use and associations with cultural factors among 3,830 Alaska Native and American Indian (AN/AI) people enrolled in the Education and Research Towards Health (EARTH) Study in 3 regions of Alaska. Cross-sectional analysis of baseline data from a cohort study. Participants (2,323 women and 1,507 men) completed a computer-assisted self-administered questionnaire that included information on diet, physical activity, life-style and cultural factors. Over 92% of participants reported eating at least 1 traditional food in the past year. The top 3 traditional foods reported were fish, moose and agutaq (a mixture of berries and fat). The percentage of people who consumed traditional foods varied by region and age but not by sex (p one traditional harvesting physical activity. Picking berries or greens, cutting/smoking fish or meat and fishing were the most common activities. Participation in traditional physical activity was highest in south-west Alaska and was higher among men than women, but did not differ by age (p speaking a Native language at home, using traditional remedies and participating in or attending traditional events (p < 0.05). The EARTH Study found relationships between traditional food use, physical activities, cultural activities and behaviours. Consumption of a variety of traditional foods and participation in traditional physical activities remain an important part of the contemporary Alaska Native life-style. Efforts to promote and sustain these foods and activities in AN/AI populations may lead to improved health outcomes.

A stream-scale model to optimize the water allocation for Small Hydropower Plants and the application to traditional systems

Razurel, Pierre; Niayifar, Amin; Perona, Paolo

2017-04-01

Hydropower plays an important role in supplying worldwide energy demand where it contributes to approximately 16% of global electricity production. Although hydropower, as an emission-free renewable energy, is a reliable source of energy to mitigate climate change, its development will increase river exploitation. The environmental impacts associated with both small hydropower plants (SHP) and traditional dammed systems have been found to the consequence of changing natural flow regime with other release policies, e.g. the minimal flow. Nowadays, in some countries, proportional allocation rules are also applied aiming to mimic the natural flow variability. For example, these dynamic rules are part of the environmental guidance in the United Kingdom and constitute an improvement in comparison to static rules. In a context in which the full hydropower potential might be reached in a close future, a solution to optimize the water allocation seems essential. In this work, we present a model that enables to simulate a wide range of water allocation rules (static and dynamic) for a specific hydropower plant and to evaluate their associated economic and ecological benefits. It is developed in the form of a graphical user interface (GUI) where, depending on the specific type of hydropower plant (i.e., SHP or traditional dammed system), the user is able to specify the different characteristics (e.g., hydrological data and turbine characteristics) of the studied system. As an alternative to commonly used policies, a new class of dynamic allocation functions (non-proportional repartition rules) is introduced (e.g., Razurel et al., 2016). The efficiency plot resulting from the simulations shows the environmental indicator and the energy produced for each allocation policies. The optimal water distribution rules can be identified on the Pareto's frontier, which is obtained by stochastic optimization in the case of storage systems (e.g., Niayifar and Perona, submitted) and by

A multi scale model for small scale plasticity

Full text.A framework for investigating size-dependent small-scale plasticity phenomena and related material instabilities at various length scales ranging from the nano-microscale to the mesoscale is presented. The model is based on fundamental physical laws that govern dislocation motion and their interaction with various defects and interfaces. Particularly, a multi-scale model is developed merging two scales, the nano-microscale where plasticity is determined by explicit three-dimensional dislocation dynamics analysis providing the material length-scale, and the continuum scale where energy transport is based on basic continuum mechanics laws. The result is a hybrid simulation model coupling discrete dislocation dynamics with finite element analyses. With this hybrid approach, one can address complex size-dependent problems, including dislocation boundaries, dislocations in heterogeneous structures, dislocation interaction with interfaces and associated shape changes and lattice rotations, as well as deformation in nano-structured materials, localized deformation and shear band

Culture, ritual, and errors of repudiation: some implications for the assessment of alternative medical traditions.

Science.gov (United States)

Trotter, G

2000-07-01

In this article, sources of error that are likely involved when alternative medical traditions are assessed from the standpoint of orthodox biomedicine are discussed. These sources include (1) biomedicine's implicit reductive materialism (manifested in its negative orientation toward placebo effects), (2) a related bias against ritual, and (3) cultural barriers to the construction of externally valid protocols. To overcome these biases, investigators must attend to ritualistic elements in alternative treatments and should recruit patients from appropriate cultural groups. Collaborative research may be the key. Benefits of collaborative research include (1) increased mutual respect and integration between culturally distinct groups and practices, (2) increased understanding and use of sophisticated techniques of empirical analysis among practitioners from the alternative traditions, (3) increased appropriation of the therapeutic benefits of ritual, and (4) enhanced overall benefit for patients of all cultural backgrounds.

Small-scale dynamo at low magnetic Prandtl numbers

2012-12-01

The present-day Universe is highly magnetized, even though the first magnetic seed fields were most probably extremely weak. To explain the growth of the magnetic field strength over many orders of magnitude, fast amplification processes need to operate. The most efficient mechanism known today is the small-scale dynamo, which converts turbulent kinetic energy into magnetic energy leading to an exponential growth of the magnetic field. The efficiency of the dynamo depends on the type of turbulence indicated by the slope of the turbulence spectrum v(ℓ)∝ℓϑ, where v(ℓ) is the eddy velocity at a scale ℓ. We explore turbulent spectra ranging from incompressible Kolmogorov turbulence with ϑ=1/3 to highly compressible Burgers turbulence with ϑ=1/2. In this work, we analyze the properties of the small-scale dynamo for low magnetic Prandtl numbers Pm, which denotes the ratio of the magnetic Reynolds number, Rm, to the hydrodynamical one, Re. We solve the Kazantsev equation, which describes the evolution of the small-scale magnetic field, using the WKB approximation. In the limit of low magnetic Prandtl numbers, the growth rate is proportional to Rm(1-ϑ)/(1+ϑ). We furthermore discuss the critical magnetic Reynolds number Rmcrit, which is required for small-scale dynamo action. The value of Rmcrit is roughly 100 for Kolmogorov turbulence and 2700 for Burgers. Furthermore, we discuss that Rmcrit provides a stronger constraint in the limit of low Pm than it does for large Pm. We conclude that the small-scale dynamo can operate in the regime of low magnetic Prandtl numbers if the magnetic Reynolds number is large enough. Thus, the magnetic field amplification on small scales can take place in a broad range of physical environments and amplify week magnetic seed fields on short time scales.

Untethered small-scale (from several millimetres down to a few micrometres in all dimensions) robots that can non-invasively access confined, enclosed spaces may enable applications in microfactories such as the construction of tissue scaffolds by robotic assembly, in bioengineering such as single-cell manipulation and biosensing, and in healthcare such as targeted drug delivery and minimally invasive surgery. Existing small-scale robots, however, have very limited mobility because they are unable to negotiate obstacles and changes in texture or material in unstructured environments. Of these small-scale robots, soft robots have greater potential to realize high mobility via multimodal locomotion, because such machines have higher degrees of freedom than their rigid counterparts. Here we demonstrate magneto-elastic soft millimetre-scale robots that can swim inside and on the surface of liquids, climb liquid menisci, roll and walk on solid surfaces, jump over obstacles, and crawl within narrow tunnels. These robots can transit reversibly between different liquid and solid terrains, as well as switch between locomotive modes. They can additionally execute pick-and-place and cargo-release tasks. We also present theoretical models to explain how the robots move. Like the large-scale robots that can be used to study locomotion, these soft small-scale robots could be used to study soft-bodied locomotion produced by small organisms.

Purpose To investigate the prospective associations between Mexican-origin mothers’ and fathers’ traditional cultural values and young adults’ health and dental care utilization and to test the moderating role of youth gender. Methods Mexican-origin parents and youth (N = 246 families) participated in home interviews and provided self-reports of parents’ cultural values (time 1) and young adults’ health status and routine health and dental care (time 2; 5 years later). Logistic regressions tested parents’ traditional cultural values as predictors of routine health and dental care, accounting for parent nativity, parent acculturation, family socioeconomic status, youth gender, youth age, and youth physical health status. We also tested whether youth gender moderated the associations between parents’ cultural values and young adults’ routine care. Results Young adults whose mothers endorsed strong familism values when they were in mid-to-late adolescence were more likely to report at least one routine physician visit in the past year as young adults (odds ratio [OR] = 3.47, 95% confidence interval [CI]: 1.23–9.83, p = .019). Furthermore, for females only, mothers’ more traditional gender role attitudes predicted reduced odds of receiving routine health (OR = .22; 95% CI: .08–.64, p = .005) and dental care (OR = .26; 95% CI: .09–.75, p = .012) in young adulthood. Conclusions Our findings highlight the importance of examining intragroup variability in culturally specific mechanisms to identify targets for addressing ethnic/racial disparities in health care utilization among Mexican-origin young adults, during a period of increased risk for health-compromising behaviors and reduced access to care.

Full Text Available Abstract Background In the present study we have investigated the cultural transmission of two types of traditional plant knowledge in two communities of North-western Patagonia, Argentina. In the Pilcaniyeu community, we studied the transmission of traditional knowledge related to horticultural practices in home-gardens, greenhouses and gardens; while in the community of Cuyin Manzano, we studied wild plant gathering customs. Methods Ethnobotanical fieldwork was conducted by means of semi-structured interviews, in which we investigated which plants are used, at what life history phase was learned, modes of transmission and who the principal transmitters were in childhood and adulthood. In both communities, each of this three aspects related to cultural transmission were categorized and the frequencies of each category were obtained. The total number of species recorded in each community was also calculated. Frequencies were analyzed with the Chi-square test of independence. Results and discussion In both communities, transmission of traditional plant knowledge begins at an early age, as a family custom, in which women play a predominant role. Wild plant use and horticultural knowledge continue to be learned during adulthood. This was particularly registered associated with horticultural learning, which receives greater influence from extension agents who are introducing new practices and technology. This outside influence, which implies novelty, could imply syncretism but also traditional knowledge loss. Conclusion Given the remarkable acculturation processes occurring at present in rural communities of Northwestern Patagonia, it might be of vital importance to document traditional knowledge of ancient practices. Moreover, it could be interesting to share our results with both populations in order to encourage participatory activities within the communities which could enhance traditional knowledge horizontal transmission, particularly among

Cultural care of older Greek Canadian widows within Leininger's theory of culture care.

1990-01-01

Cultural care themes were abstracted from a large scale study of older Greek Canadian widows conceptualized within Leininger's theory of Cultural Care Diversity and Universality. Ethnonursing, ethnographic, and life health-care history methods were used. Data were collected using observation-participation and interviews in three Greek Canadian communities with 12 widowed key informants and 30 general informants. Enabling tools used were interview inquiry guides, Leininger's Life History Health Care Protocol, Leininger's Acculturation Rating and Profile Scale of Traditional and Non-Traditional Lifeways, and field journal recordings. Data were analyzed using Leininger's phases of analysis for qualitative data. The two major cultural care themes which were abstracted from the raw data and patterns were: (1) Cultural care for Greek Canadian widows meant responsibility for, reciprocation, concern, love, companionship, family protection, hospitality, and helping, primarily derived from their kinship, religious, and cultural beliefs, and values, and (2) Cultural care continuity diminished the spousal care void and contributed to the health of Greek Canadian widows. These findings will stimulate future nursing research related to cultural care of diverse populations and guide nursing practice to provide culturally congruent care which will assist widows to reduce their spousal care void. The author thanks Dr. Madeleine Leininger, Dr. Judith Floyd, Dr. Marjorie Isenberg, and Dr. Bernice Kaplan for their guidance in completing the large scale study on which this article is based.

From Suazoid to folk pottery: pottery manufacturing traditions in a changing social and cultural environment on St. Lucia

2004-01-01

Full Text Available Overview of pottery manufacturing traditions in St Lucia, placed within the island's cultural history from pre-Columbian times up to present Afro-Caribbean folk pottery. Authors focus on manufacturing processes in different cultural traditions through history, looking at raw materials used, the shaping and finishing, decoration, and firing process. First, they sketch St Lucia's habitation history since the first Amerindian settlers in 200 AD, and evidence of pottery, which climaxed in the later Suazoid period pottery since about 1150 AD, and discuss how later European colonization and arrival of Africans contributed to the decline of Amerindian traditions, replaced by European and West African pottery traditions, although some Amerindian traditions remained. The pottery manufacturing of 3 main cultural traditions are examined, discussing differences, as well as similarities due to cultural blending: Suazoid pottery, later Amerindian Island Carib pottery, with origins in the Guianas region, related to the Kar'ina, and current St Lucian, West African-influenced, "folk pottery". Authors conclude that all 3 traditions mainly use local clay, and include hand-built and low-fired pottery. Shaping techniques include coiling, and in today's pottery also fashioning with smaller lumps. Surfaces are smooth and polished in today's pottery, but more scraped and scratched in Suazoid vessels. Further, they find that decoration is uncommon in today's pottery, while Suazoid ceramics included decorations, and that vessel shapes tend to be simple in all 3 traditions. They also find that women have been the principal potters through time, although pottery was a male activity among the Island Caribs in the mid-17th c.

Full Text Available Research into cultural heritage which implements augmented reality technology is limited. Most recent research on cultural heritage are limited on storing data and information in the form of databases, this creates a disadvantage for people who wants to see and feel at the same moment on actual cultural heritage objects. This paper, proposes a solution which could merge the existing cultural object with people using augmented reality technology. This technology would preserve traditional instrument in the form of 3D object which can be digitally protected. The result showed that the use of augmented reality on preserving cultural heritage would benefit people who try to protect their culture.

1997-12-31

The purpose of the study was to clarify how running a small-scale bakery can provide a farming enterprise with its primary or secondary source of livelihood. A questionnaire and interviews were conducted to clarify the current situation concerning small-scale rural bakeries. The experimental part of the study looked into different manners of production, devices used in preparing and processing of doughs, and baking of different kinds of pastries in different types of ovens in laboratory conditions. Based on the results obtained, solutions serving as examples were formulated for small-scale bakeries run with various modes and methods of production. Additionally, market reviews were conducted concerning appropriate equipment for small-scale bakeries. Baking for commercial purposes on the farm is still something new as ca. 80 % of the enterprises covered by the study had operated for no more than five years. Many entrepreneurs (ca. 70 %) expressed a need for supplementary knowledge from some field related to baking. Rural bakeries are small-scale operations with one-person enterprises amounting to 69 % and two-person enterprises to 29 %. Women are primarily responsible for baking. On average, the enterprises baked seven different products, but the amounts baked were usually small. In the experimental part of the study, loaves of rye bread were baked using five different types and sizes of oven accommodating 5-22 loaves of rye bread at the one time. The oven type was found not to affect bread structure. The energy consumption for one ovenful varied between 2.4 and 7.0 kWh, i.e. 0.25-0.43 kWh per kilo. When baking rolls (30-140 rolls at a time), the power consumption varied between 1.2 and 3.5 kWh, i.e. 0.32-0.53 kWh per kilo. The other devices included in the comparative study were an upright deep-freezer, a multi-temperature cabinet and a fermenting cabinet. Furthermore, making rolls by hand was compared to using a machine for the same job, and likewise manual

Full Text Available The following paper explores socio-cultural impacts of large-scale cruise liner tourism on the traditional bazaar (souq in the district of Mutrah. The souq is located opposite the port in the Omani capital Muscat. Large-scale cruise tourism in Muscat started only in 2004 and has increased in scale and numbers in the past years. 24 cruise vessels with around 7600 passengers arrived in Muscat in 2005. Seven years later 135 cruise liners carrying 257,000 tourists docked in Muscat. Due to this dramatic rise of international cruise ships, the socio-cultural impacts have increased for local residents, shop vendors/owners and tourists alike. To capture those socio-cultural impacts on Souq Mutrah, a survey of cruise tourists was conducted by a questionnaire. In addition, the researcher used participatory observation, counting, and in-depth interviews with different stakeholders of the local community and different types of tourists during the cruise seasons 2012/13 and 2013/14. Moreover, content analysis of statistics and local media publications were used. Results indicate that the souq has become “the core of a tourist bubble”, where crowding is a major problem and local residents avoid the place. The social carrying capacity of the souq has been reached. Omani vendors are leaving their businesses and renting their shops out to expatriates. Since contemporary cruise tourists are low spenders, expatriate shop sellers have become more aggressive.

Small scale mining cooperatives in Bolivia: From lifeguard of the poor to machinery of political manipulation

Directory of Open Access Journals (Sweden)

Felix Carrillo

2013-11-01

Full Text Available This article argues that relations between social movements and organizations and the State are not only developed based on defended objectives and interests in political negotiations, but are also developed within particular situations, of specific cultures and histories. Our investigation about the relationship between mining cooperatives, their national organization, and the Bolivian State demonstrates the crucial importance of considering historical aspects, of collective memory, some regional and others within the organizations themselves. The traditions, memories, and abilities incorporated in the mining organizations and in the political realm will influence the way in which different parts relate to one another, design their strategies, and adapt to changing circumstances. This topic is illustrated firstly through a historical and contemporary account of mining in Bolivia focused in the sector of small scale mining. This is followed by outlining the position that cooperative mining occupies in the country and the strategies and self esteem that they display. Next, our case study is addressed: the ASOBAL cooperative. In the national outline, like in our case study, we connect the positions and strategieswith themes of identity, memory, and place.

To address this disparity, research has begun to investigate the role of culture, ethnicity, and experiences with racism on food choices and health interventions. The aim of the current study was to develop and evaluate a new scale measuring the extent to which individuals' culture, as they perceive it, influences perceptions of food-related health messages. A diverse sample of 422 college students responded to the item pool, as well as surveys on race-related stress, self-efficacy in making healthy food choices, ethnic identity, and social support for health-related behaviors. Exploratory and confirmatory factor analyses produced a five-factor model: Connection (the extent to which food connected individuals with their culture), Authority (beliefs that health care providers were familiar with individuals' cultural foods), Unhealthy Food Perceptions (beliefs that individuals' cultural foods were perceived as unhealthy), Healthy Food Perceptions (beliefs that others perceive individuals' cultural foods to be healthy), and Social Value (the extent to which social relationships are improved by shared cultural food traditions). Authority and Healthy Food Perceptions were related to individuals' confidence in their ability to make healthy food choices. Authority was inversely correlated with negative coping with racism-related events. Ethnic identity was significantly correlated with all but Unhealthy Food Perceptions. Race/ethnicity differences were identified for Healthy Food Perceptions, Unhealthy Food Perceptions, Social Value, Connection, but not Authority. Applications and suggestions for further research using the Culturally-based Communication about Health, Eating, and Food (CHEF) Scale are proposed. Copyright © 2015 Elsevier Ltd.

Biofuels in Africa: growing small-scale opportunities

Energy Technology Data Exchange (ETDEWEB)

Sulle, Emmanuel [Tanzania Natural Resources Forum (Tanzania, United Republic of); Fauveaud, Swan [Renewable Energy Group, Environment and Solidarity (France); Vermeulen, Sonja

2009-11-15

Global demand for climate-friendly transport fuels is driving vast commercial biofuels projects in developing countries. At the opposite end of the spectrum is small-scale bioenergy production. This offers a way for the poor to meet their energy needs and diversify their livelihoods without compromising food security or environmental integrity. Governments hope that it will be possible to combine the advantages of both large- and small-scale production of biofuels to generate energy security and GDP at the national level, while opening up local opportunities. In Africa, most governments are keen to attract foreign direct investment, and see big business as a strategic means of scaling up rural development. But there is a middle way. By encouraging business models that bridge large and small enterprise, African governments could show that commercial competition can go hand in hand with a range of real local benefits.

Health and Safety Management for Small-scale Methane Fermentation Facilities

Science.gov (United States)

Yamaoka, Masaru; Yuyama, Yoshito; Nakamura, Masato; Oritate, Fumiko

In this study, we considered health and safety management for small-scale methane fermentation facilities that treat 2-5 ton of biomass daily based on several years operation experience with an approximate capacity of 5 t·d-1. We also took account of existing knowledge, related laws and regulations. There are no qualifications or licenses required for management and operation of small-scale methane fermentation facilities, even though rural sewerage facilities with a relative similar function are required to obtain a legitimate license. Therefore, there are wide variations in health and safety consciousness of the operators of small-scale methane fermentation facilities. The industrial safety and health laws are not applied to the operation of small-scale methane fermentation facilities. However, in order to safely operate a small-scale methane fermentation facility, the occupational safety and health management system that the law recommends should be applied. The aims of this paper are to clarify the risk factors in small-scale methane fermentation facilities and encourage planning, design and operation of facilities based on health and safety management.

Successful large-scale hatchery culture of sandfish (Holothuria scabra using micro-algae concentrates as a larval food source

Directory of Open Access Journals (Sweden)

Thane A. Militz

2018-02-01

Full Text Available This paper reports methodology for large-scale hatchery culture of sandfish, Holothuria scabra, in the absence of live, cultured micro-algae. We demonstrate how commercially-available micro-algae concentrates can be incorporated into hatchery protocols as the sole larval food source to completely replace live, cultured micro-algae. Micro-algae concentrates supported comparable hatchery production of sandfish to that of live, cultured micro-algae traditionally used in large-scale hatchery culture. The hatchery protocol presented allowed a single technician to achieve production of more than 18,800 juvenile sandfish at 40 days post-fertilisation in a low-resource hatchery in Papua New Guinea. Growth of auricularia larvae fed micro-algae concentrates was represented by the equation length (μm = 307.8 × ln(day + 209.2 (R2 = 0.93 while survival over the entire 40 day hatchery cycle was described by the equation survival = 2 × day−1.06 (R2 = 0.74. These results show that micro-algae concentrates have great potential for simplifying hatchery culture of sea cucumbers by reducing infrastructural and technical resources required for live micro-algae culture. The hatchery methodology described in this study is likely to have applicability to low-resource hatcheries throughout the Indo-Pacific and could support regional expansion of sandfish hatchery production.

The situation of rural women in Spain: the case of small-scale artisan food producers

Directory of Open Access Journals (Sweden)

Veronica Escurriol Martinez

2014-11-01

Full Text Available Rural women's discrimination and the lack of effective implementation of the legislation on gender equality is a phenomenon found around the world. Women have been traditionally the responsible of family care and feeding, thus they have developed productive tasks that allow combining productive and reproductive activities in the farm. Food processing is one of these activities and it allows women to have a paid work or to complement agrarian rents in a context where most of agricultural works are vetoed to them. Nevertheless, women are usually linked to small-scale agricultural projects which prioritize quality and local food production, and the expansion of industrial food systems has worsened the situation of artisan women. In the present research we aimed, through the use of qualitative methodologies, at conducting a diagnosis of the situation of women leading small-scale food transformation projects in Spain while eliciting their main difficulties, needs and claims.

Small-scale impacts as potential trigger for landslides on small Solar system bodies

Science.gov (United States)

Hofmann, Marc; Sierks, Holger; Blum, Jürgen

2017-07-01

We conducted a set of experiments to investigate whether millimetre-sized impactors impinging on a granular material at several m s-1 are able to trigger avalanches on small, atmosphereless planetary bodies. These experiments were carried out at the Zentrum für angewandte Raumfahrttechnologie und Mikrogravitation (ZARM) drop tower facility in Bremen, Germany to facilitate a reduced gravity environment. Additional data were gathered at Earth gravity levels in the laboratory. As sample materials we used a ground Howardites, Eucrites and Diogenites (HED) meteorite and the Johnson Space Center (JSC) Mars-1 Martian soil simulant. We found that this type of small-scale impact can trigger avalanches with a moderate probability, if the target material is tilted to an angle close to the angle of repose. We additionally simulated a small-scale impact using the discrete element method code esys-particle. These simulations show that energy transfer from impactor to the target material is most efficient at low- and moderate-impactor inclinations and the transferred energy is retained in particles close to the surface due to a rapid dissipation of energy in lower material layers driven by inelastic collisions. Through Monte Carlo simulations we estimate the time-scale on which small-scale impacts with the observed characteristics will trigger avalanches covering all steep slopes on the surface of a small planetary body to be of the order 105 yr.

Export horticulture – empowering female small-scale farmers in Kenya?

Directory of Open Access Journals (Sweden)

Velte, Maria

2014-09-01

Full Text Available Export horticulture is one of Kenya’s most dynamic sectors, with the Mount Kenya Region playing a crucial role as a result of its professional large- and small-scale production and marketing structures. The sector is consequently referred to as a “success story of African regional development” (Dolan and Sutherland 2002: 1. A qualitative case study was carried out to understand the impacts on gender inequality of the integration of horticultural smallholdings into the fresh fruit and vegetable (FFV supply chain to the European market. It will be outlined how export horticulture affects female small-scale farmers with reference to local distribution channels, the organisation of the farm as a group or an individual player, and the specific organisation of labour on the farm. The focus here is on the traditional division of labour, ownership and mobility patterns, as well as knowledge and income. The study shows that the influence of the integration in the FFV chain on gender inequality is conditioned by both the type of relations to the buyers and the internal and institutional organisation of the smallholding. Surprisingly, in some areas of the primarily male-dominated rural society, an integration in the form of outgrower schemes that resembles Gereffi et al.’s model of a captive value chain, with women farmers exclusively responsible for export production, can enhance gender equality, as women gradually gain more decision-making power and greater independence.

Cultural diversity among nursing students: reanalysis of the cultural awareness scale.

Science.gov (United States)

Rew, Lynn; Becker, Heather; Chontichachalalauk, Jiraporn; Lee, H Y

2014-02-01

Nurses are educated to provide culturally competent care. Cultural competence begins with cultural awareness, a concept previously measured with the Cultural Awareness Scale (CAS). The purpose of this study was to reanalyze the CAS to determine construct validity and differences in cultural awareness among students of varying educational levels and experiences. The sample consisted of 150 nursing students (92% female, 33.6% racial minorities). Confirmatory factor analysis yielded three factors (CFI = 0.868, TLI = 0.854, RMSEA = 0.065, and SRMR = 0.086). Cronbach's alpha ranged from 0.70 to 0.89. There were significant differences among educational levels, with lower division BSN students generally scoring higher than upper division and master's of science in nursing students. Students who had taken courses on cultural diversity or global health generally outscored those who had not taken such courses. Findings support the validity of the CAS and its applicability to research studies of cultural awareness in nursing. Copyright 2014, SLACK Incorporated.

Is small beautiful? A multicriteria assessment of small-scale energy technology applications in local governments

International Nuclear Information System (INIS)

Burton, Jonathan; Hubacek, Klaus

2007-01-01

In its 2003 White Paper the UK government set ambitious renewable energy targets. Local governments and households have an increasing role in the overall energy system as consumers, suppliers of smaller-scale applications and citizens discussing energy projects. In this paper, we consider if small-scale or large-scale approaches to renewable energy provision can achieve energy targets in the most socially, economically and environmentally (SEE) effective way. We take a local case study of renewable energy provision in the Metropolitan Borough of Kirklees in Yorkshire, UK, and apply a multi-criteria decision analysis methodology to compare the small-scale schemes implemented in Kirklees with large-scale alternatives. The results indicate that small-scale schemes are the most SEE effective, despite large-scale schemes being more financially viable. The selection of the criteria on which the alternatives are assessed and the assigned weights for each criterion are of crucial importance. It is thus very important to include the relevant stakeholders to elicit this information

Small is beautiful: Marine small-scale fisheries catches from the South-West Maluku Regency

Science.gov (United States)

Hutubessy, BG; Mosse, JW; Hayward, P.

2017-10-01

The fisheries data supplied by fisheries agency have served as the primary tool for regional fisheries statistics. However, it is recognized these data are incomplete and often underestimate actual catches, particularly for small-scale fisheries. There is no widely accepted definition of small-scale fisheries or global data on number of small-scale fishers and their catches. This study reconstructed total marine catches from 1980 to 2015 for South-west Maluku (MBD) regency, by applying an established catch construction approach utilizing all available quantitative and qualitative data, combined with assumption-based estimations and interpolations. As newly established regency since 2009, there is lack of fisheries data available which is needed for fisheries management. Fishers’ knowledge is important information taken from to construct long-term fisheries data. Estimated total fish withdrawal from MBD waters was 86,849.66 tonnes during 1980 - 2015, dominated by pelagic fishes. Consistency of estimated total removal and total landings at MBD regency play important role in small-scale fisheries management and this method of visualizing the history of fishery from poor-data condition might be an optimistic effort.

Preservation of Cultural Heritage Embodied in Traditional Crafts in the Developing Countries. A Case Study of Pakistani Handicraft Industry

Directory of Open Access Journals (Sweden)

Yongzhong Yang

2018-04-01

Full Text Available Cultural heritage embodied in traditional crafts is an integral part of any nation which reflects the culture and tradition of a particular region. Although the importance of handicraft has been widely recognized, the literature regarding preservation of traditional craft is scarce. The present paper aimed to explore and identify issues faced by traditional craftsmanship in developing countries and to address those issues in order to contribute to the sustainability of traditional craft heritage and ensure continuous transmission of craft skills and knowledge from generation to generation. Our study identified several key issues which poses substantial challenges to the preservation of traditional craft heritage in developing countries. In order to add empirical evidence, we examined the case of Pakistani handicraft industry that provided further understanding of highlighted issues which traditional craft heritage face. We have suggested some policies to promote, develop and preserve the traditional craft heritage. The significance of these policy suggestions is underlined with the case study of Pakistan.

Brusentsev, E Iu; Igonina, T N; Amstislavskiĭ, S Ia

2014-01-01

This review covers the basic principles and methods of in vitro culture of preimplantation mammalian embryos. The features of in vitro development of embryos of various species of animals with allowance for the composition of nutrient media are described, with special attention paid to those species that have traditionally been consideredas laboratory (i.e., mice, rats, and hamsters). The effects of suboptimal culturing conditions of preimplantation embryos on the formation of the phenotype of individuals developed from these embryos are discussed. New approaches to optimize the conditions of the development of preimplantation mammalian embryos in vitro are analyzed.

Agricultural Incentives: Implications for Small-Scale and Subsistence Farming in the US Caribbean Islands

Science.gov (United States)

Alvarez-Berrios, N.; Parés-Ramos, I.; Gould, W. A.

2017-12-01

The effects of climate change threaten the world's most sensitive agroecosystems and our potential to reach agricultural productivity levels needed to feed a projected global population of 9.7 billion people by 2050. The US Caribbean agriculture is especially vulnerable to the effects of climate change, due to the region's frequent exposure to extreme weather events, its geographic and economic scale, shortage of labor force, and rapid urban expansion. Currently, agriculture contributes less than 1% of the island's GDP, and over 80% of the food consumed in the region is imported. Despite low production levels, there is widespread interest in reinvigorating the agricultural sector's contribution to the economy. Local and federal institutions play a major role strengthening the agricultural sector by providing access to incentives, loans, and education for best management practices. However, many of these efforts conform to agricultural systems of larger scale of production and temperate environments. In this study, we explore agricultural incentives programs and their implication for highly diverse, small-scale, and subsistence operations that characterize agricultural systems in Puerto Rico and the US Virgin Islands. We analyze records and maps from the USDA Farm Service Agency, to typify participating farms, and to track changes in land cover, farm size, crop diversity, practices, and production levels resulting from their enrollment in such programs. Preliminary results indicate that many incentives programs are not tailored to agricultural tropical systems and prescribe alternatives that exclude traditional farming methods employed in small-scale and subsistence farms (e.g. crop insurance that benefit monoculture over intercropped systems). Moreover, many of the incentives are contradictory in their recommendations (e.g., crop insurance benefit sun-grown coffee production, while best agricultural practices recommend agroforestry with shade-grown coffee

On the impacts of traditional Chinese culture on organ donation.

Science.gov (United States)

Cai, Yu

2013-04-01

This article examines the impact of traditional Chinese culture on organ donation from the perspective of Confucianism, Buddhism, and Taoism. In each of these cultural systems, it appears that there are some particular sayings or remarks that are often taken in modern Chinese society to be contrary to organ donation, especially cadaveric organ donation. However, this article argues that the central concerns of Buddhism, Confucianism, and Taoism are "great love," "ren," and "dao," which can be reasonably interpreted to support organ donation. The author understands that each cultural system, in order to play its cultural function, must have its central concerns as well as relevant ritual practices (li) that incarnate its religious and ethical commitments. That is, each plays a general cultural role, which influences organ donation in particular not merely through abstract or general ethical principles and teachings, but through a combination of ethical teachings and the forming of particular ritual practices. This article contends that the primary reason Chinese individuals fail to donate sufficient cadaveric organs for transplantation is not because particular remarks or sayings from each of these systems appear to conflict with donation. Neither is it that the central concerns of these systems cannot support cadaveric donation. Rather, it is that modern Chinese individuals have failed to develop and secure relevant ritual practices that support the central concerns of organ transplantation. The article concludes that in order to promote more donations, there is a need to form relevant ritual practices supporting organ donation in conformity with the central concerns of these cultural systems.

Banwari, Meel

2015-03-01

Traditional circumcision (initiation) is an integral part of the Xhosa speaking communities. Circumcision is the first step towards manhood. It involves a number of cultural, religious, legal and ethical issues, which in terms of the constitution of the Republic of South Africa, are rights that must be protected. To highlight the problem of circumcision related death in South Africa. This case report examines a 16- year boy who had died as result of botched circumcision by an unqualified traditional surgeon. He kept the boy in his custody despite his serious illness. He applied a tight bandage to control the bleeding, resulting in gangrene of the penis followed by septicemia. The histories, postmortem findings, cause of death and medico- legal and social aspects have been discussed in this manuscript. There are unacceptable deaths related with circumcision in South Africa. The right to life cannot be sacrificed at the altar of culture and politics.

Full Text Available In Russia small-scale business originated in the end of 1980s duringRestructuring. It has been developing as fast as Russian economics.Unlike large industrial companies, which just continued to run businessas they used to, small-scale businessmen had to start from scratch ordisaffiliate with large organizations. Basically, in 1990-s small-scale business as a financial institute was self-regulated due to its highcriminalization and nonpayment of tax.For a period of only 25 years small-scale business has improved muchand now provides well-being to the country. The improvement happeneddue to the following factors:- propitious economic and political climate of the country against thebackground of global economy and the years of restricting- important and useful measures for economic development were taken - important and useful measures for development of small-scale enterprises were takenThe development of this new financial institute is quite fast, but historyhas other examples of such phenomenon. In the 21st century RussianFederation adopted experience of advanced countries and imposed it onits historic experience. However, we can’t say that small-scale business is on its top of development in our country. Nowadays development of small-scale business is one of the priorities of the Russian government.

This paper is an attempt to explain this phenomenon, while at the same time connecting my analysis to the wider issue of globalization. My analysis is very tentative and is based mainly on my study of youth culture of the University of the Philippines. The analysis therefore can only be considered as preliminary and may not necessarily be applied to other forms of youth culture and subculture in other localities without further qualifications.

Can we really use available scales for child and adolescent psychopathology across cultures? A systematic review of cross-cultural measurement invariance data.

Stevanovic, Dejan; Jafari, Peyman; Knez, Rajna; Franic, Tomislav; Atilola, Olayinka; Davidovic, Nikolina; Bagheri, Zahra; Lakic, Aneta

2017-02-01

In this systematic review, we assessed available evidence for cross-cultural measurement invariance of assessment scales for child and adolescent psychopathology as an indicator of cross-cultural validity. A literature search was conducted using the Medline, PsychInfo, Scopus, Web of Science, and Google Scholar databases. Cross-cultural measurement invariance data was available for 26 scales. Based on the aggregation of the evidence from the studies under review, none of the evaluated scales have strong evidence for cross-cultural validity and suitability for cross-cultural comparison. A few of the studies showed a moderate level of measurement invariance for some scales (such as the Fear Survey Schedule for Children-Revised, Multidimensional Anxiety Scale for Children, Revised Child Anxiety and Depression Scale, Revised Children's Manifest Anxiety Scale, Mood and Feelings Questionnaire, and Disruptive Behavior Rating Scale), which may make them suitable in cross-cultural comparative studies. The remainder of the scales either showed weak or outright lack of measurement invariance. This review showed only limited testing for measurement invariance across cultural groups of scales for pediatric psychopathology, with evidence of cross-cultural validity for only a few scales. This study also revealed a need to improve practices of statistical analysis reporting in testing measurement invariance. Implications for future research are discussed.

Dysphagia in adults arises from a range of causes including acquired neurological disorders and some cancers. Previous research has suggested that treatment using neuromuscular electrical stimulation (NMES) when used in conjunction with conventional therapy is effective. This review describes the recent literature and a small prospective case series carried out in the United Kingdom. This study contributed to support National Institute of Clinical Excellence (NICE) guidance for clinicians who wish to include NMES in a rehabilitation programme for dysphagic patients, specifically with reference to safety and the impact on swallowing function of this intervention. In 2014, the UK NICE issued guidelines enabling UK therapists to trial the use of NMES, but the guidelines also sought additional evidence on the impact on swallowing function of NMES and the incidence of side effects. This small prospective case series investigated both of these aspects with a group of patients with dysphagia of neurological origin who had not achieved adequate swallowing function with traditional therapy alone. This study recruited 10 adult patients with dysphagia of neurological origin. All had previously received traditional swallowing therapy for at least 6 months but only achieved a Functional Oral Intake Scale of 4 or less (a scale for amounts and types of oral intake). The total study period was 10 weeks for each subject comprising 5 weeks of traditional therapy delivered three times a week followed by 5 weeks of NMES concurrent with traditional therapy (NMES + traditional therapy) delivered three times a week using the VitalStim stimulator (VitalStim Therapy, UK). In addition, the Quality of Life in Swallowing and Eating Assessment Tool 10 (quality of life scales) were determined to allow comparison between studies. Nine subjects achieved an improvement in swallowing function after NMES + traditional therapy was measured using the Functional Oral Intake Scale, giving a

The overtone gain medium of a small-scale HF overtone laser was probed using a sub-Doppler tunable diode laser. Two-dimensional spatially resolved small signal gain and temperature maps were generated for several ro-vibrational transitions in the HF (v=2{yields}v=0) overtone band. Our results compare well with previous measurements of the overtone gain in a similar HF laser device. (orig.)

Anthocyanins are widely distributed, glycosylated, water-soluble plant pigments, which give many fruits and flowers their red, purple or blue colouration. Their beneficial effects in a dietary context have encouraged increasing use of anthocyanins as natural colourants in the food and cosmetic industries. However, the limited availability and diversity of anthocyanins commercially have initiated searches for alternative sources of these natural colourants. In plants, high-level production of secondary metabolites, such as anthocyanins, can be achieved by engineering of regulatory genes as well as genes encoding biosynthetic enzymes. We have used tobacco lines which constitutively produce high levels of cyanidin 3-O-rutinoside, delphinidin 3-O-rutinoside or a novel anthocyanin, acylated cyanidin 3-O-(coumaroyl) rutinoside to generate cell suspension cultures. The cell lines are stable in their production rates and superior to conventional plant cell cultures. Scale-up of anthocyanin production in small scale fermenters has been demonstrated. The cell cultures have also proven to be a suitable system for production of 13 C-labelled anthocyanins. Our method for anthocyanin production is transferable to other plant species, such as Arabidopsis thaliana, demonstrating the potential of this approach for making a wide range of highly-decorated anthocyanins. The tobacco cell cultures represent a customisable and sustainable alternative to conventional anthocyanin production platforms and have considerable potential for use in industrial and medical applications of anthocyanins.

2016-06-01

Full Text Available Purpose of this paper is to identify the tendency of shrimp value chain development and impact of its governance on the small scale shrimp farmers in Vietnam. Design/methodology/approach - Data from the shrimp farmers surveys in Mekong delta, Vietnam from 2008-2010 with the update information in 2014 were taken to analyse by the value chain analysis method. Findings – Traditional governance type of the shrimp value chain in the early state (before 2004 showed the different levels of coordination of farmers with collectors, among collectors, and collectors with processing plants. In this type of governance, trust and linkages are inextricably linked. However, they are not strong. The processing plants determine shrimp prices and quality requirement in the market while many collectors do not seem to be highly responsible for the quality of their products. To avoid this limitation, with the governmental support policy to improve farmers’ income, the processing plants set up a direct buying from farmers under contracts. These contracts led to a new governance type with an expectation of improving farmers' position. However, this model was broken due to several reasons including un-controlled shrimp raw material from small scale and individual farmers. Consequently, processors now tend to establish their own raw material zone to comply shrimp quality assurance, and eject the existence of farmers. This will lead small scale farmers to very difficult problems in finding the market. Poverty and social problems of small scale farmers might appear. The result recommends a greater strengthening and tightening of the value chain. Re-organizing shrimp farmers into legal teams or groups that help farmers to re-participate in the game with others actor in the chain is crucial. Research limitations/implications - The research mainly follows inductive approach in w

Full Text Available Language and culture are two aspects which interchange each other where the language is a medium to get information about the culture. As the product of language and culture, oral tradition plays a vital role in Maluku not only as the most powerful and sacred chant that regulate the life of people but also as the folk song that contains history, advice, and prayer. Kapata nowadays is assumed as the endangered oral traditions in Maluku. To rediscover the endangered oral traditions, descriptive qualitative research by using interview and library study in gaining the supporting information was implemented. Furthermore, this research was aimed (1 to figure out the history of Kapata and the way to preserve it (2 to map out the categories of Kapata and its function in social life, and (3 to elaborate the meaning of language expression conveyed in Kapata. Through this research, it is hoped that Kapata can be preserved by implementing it in formal education, art performance and framing in an advanced documentation so that all generations of Maluku are able to not only to recognize and make use it in social life as the way to preserve the Kapata as an endangered oral tradition.

Full Text Available In order to explore the influence mechanism of traditional Chinese culture values on urban residents’ acceptance of the reuse of recycled water, this paper selects interdependent self-constructional indicators representing the dependency relation between people as the representative of traditional culture values. In this paper, interdependent self-constructional indicators are introduced based on a technology acceptance model (TAM, in order to establish a hypothesis model. Following this, the writer conducts a study that shows the influence on the acceptance of recycled water through the formation of interdependent self-construction. Finally, the influence mechanism of traditional cultural values on citizens’ behavior regarding the reuse of recycled water is determined. To start with, the writer verifies the reliability and validity of data from 584 samples, and then tests the goodness-of-fit between the sample data and the hypothesis model by AMOS21.0 (software. On this basis, the writer analyzes the direct and indirect influence through the hypothesis model and finds that the interdependent self-constructional intensity will accelerate the acceptance process of recycled water technology by positively influencing a change in the residents’ attitudes to recycled water. The conclusion shows that traditional Chinese cultural values have a certain influence on urban residents’ acceptance of the reuse of recycled water. Meanwhile, the writer clarifies the influence’s mechanism.

Atomistic Simulations of Small-scale Materials Tests of Nuclear Materials

Degradation of materials properties under neutron irradiation is one of the key issues affecting the lifetime of nuclear reactors. Evaluating the property changes of materials due to irradiations and understanding the role of microstructural changes on mechanical properties are required for ensuring reliable and safe operation of a nuclear reactor. However, high dose of neuron irradiation capabilities are rather limited and it is difficult to discriminate various factors affecting the property changes of materials. Ion beam irradiation can be used to investigate radiation damage to materials in a controlled way, but has the main limitation of small penetration depth in the length scale of micro meters. Over the past decade, the interest in the investigations of size-dependent mechanical properties has promoted the development of various small-scale materials tests, e.g. nanoindentation and micro/nano-pillar compression tests. Small-scale materials tests can address the issue of the limitation of small penetration depth of ion irradiation. In this paper, we present small-scale materials tests (experiments and simulation) which are applied to study the size and irradiation effects on mechanical properties. We have performed molecular dynamics simulations of nanoindentation and nanopillar compression tests. These atomistic simulations are expected to significantly contribute to the investigation of the fundamental deformation mechanism of small scale irradiated materials

An increase in demand for computing power in academia has necessitated the need for high performance machines. Computing power of a single processor has been steadily increasing, but lags behind the demand for fast simulations. Since a single processor has hard limits to its performance, a cluster of computers can have the ability to multiply the performance of a single computer with the proper software. Cluster computing has therefore become a much sought after technology. Typical desktop computers could be used for cluster computing, but are not intended for constant full speed operation and take up more space than rack mount servers. Specialty computers that are designed to be used in clusters meet high availability and space requirements, but can be costly. A market segment exists where custom built desktop computers can be arranged in a rack mount situation, gaining the space saving of traditional rack mount computers while remaining cost effective. To explore these possibilities, an experiment was performed to develop a computing cluster using desktop components for the purpose of decreasing computation time of advanced simulations. This study indicates that small-scale cluster can be built from off-the-shelf components which multiplies the performance of a single desktop machine, while minimizing occupied space and still remaining cost effective.

Comments on "Some Relations Among Cultural Traditions, Nuptiality and Fertility".

Facts employed in formulating Ansley Coale's interpretation of European historical demographic transition have largely been in the public domain for a long time. Coale's achievement, however, in bringing pertinent information together to form a theoretical framework is applauded, and is acknowledged as being an important contribution to the traditional use of demographic transition. Beyond this general interest and broad approval, the author critiques various points of Coale's thesis. First, he notes the need to be suspicious of high correlations found between mean age at 1st marriage and total fertility rate. Second, he is unsure of the role played by servants in explaining the comparatively later marriage age of western Europeans. Finally, the author considers marked fertility declines in China, Taiwan, and Korea. These declines run strongly counter to the traditional cultures of these countries. Moreover, the high life expectations at birth, strong episodic economic development in Taiwan and Korea, and serious autocratic government interference in China are atypical of experiences in most developing countries. Traditional family planning in these 3 countries was simply a facilitator of demographic transition. The experiences of China, Taiwan, Korea, and Bangladesh support the ineffectiveness of imposing programs from either within or outside of a country.

Full Text Available The agriculture played an important role in the industrialization process of Mexico. However, the agricultural policy of State has isolated small scale farmers, giving priority just to large agricultural exporters. This study analyzes the implications that can have fair trade for the Mexican small scale farmers. The fair trade tries to cover the production cost and basic necessities for the small scale farmers, making direct ties between producers and consumers. This type of linkage guarantees the minimum price and the extra social payment to the small scale farmers, grouped in cooperatives o associations.Coffee is one of the most known fair trade product, and Mexico is one of the most important coffer exporters of the world. The fair trade of coffee production where many small farmers work is carried out by cooperative like UCIRI (Unión de Comunidades Indígenas de la Región Istmo. The case study shows that fair trade cannot provide complete answers to the all problems that have small farmers. But, since fair trade tries to promote small farmers well-being and many small farmers could get rid of extreme poverty thanks to fair trade, it might be possible to say that fair trade can be one valuable option for the sustainable development of small farmers.

Culture and biomedical care in Africa: the influence of culture on biomedical care in a traditional African society, Nigeria, West Africa.

Biomedical Care in Africa and the influence of culture on the health-seeking behaviour of Africans can not be underestimated; many African cultures have different understanding of the causes of disease which more often affect our public health system, policy, planning and implementations. The traditional African healer unlike a doctor trained in western biomedicine, looks for the cause of the patient's ailments as misfortune in relationship between the patient and the social, natural and spiritual environments. The complexity of African society with different cultural and religious practices also reflects on the people's attitude and understanding of their health matters. This paper is an overview of the cultural influence on biomedical care in a traditional African society, Nigeria, West Africa. A research on the patients' health seeking behaviour and Primary Health Care service organization in 10 health centres in the five eastern states of the Federal Republic of Nigeria was carried out using a multistage cross-sectional study. A semi-structured questionnaire was administered to the health care providers and patients while an in-depth semi- structured interview was also conducted. We observed there is underutilization of health care services at the primary level because most people do not accept the model of health care system provided for them. Most people believe diseases are caused by supernatural beings, the handiwork of neighbours or vengeance from an offended god as a result of transgressions committed in the past by an individual or parents. This group of people therefore prefers seeking traditional medicine to seeking orthodox medicine and often ends up in the hands of witch doctors who claim to have cure to almost all the diseases. Biomedical care in Africa is influence by culture because of different understanding of what ailment is and also due to limited knowledge of health matters, poverty and ignorance. There is a need therefore to focus on health

Small-scale gold miners in Ghana have been using mercury to amalgamate gold for many years. Mercury is toxic even at low concentration. We assessed occupational exposure of small-scale gold miners to mercury in Prestea, a gold mining town in Ghana . We conducted a cross-sectional study in which we collected morning urine samples from 343 small-scale gold miners and tested for elemental mercury. Data on small-scale gold miner's socio-demographics, adverse health effects and occupational factors for mercury exposure were obtained and analyzed using SPSS Version 16 to determine frequency and percentage. Bivariate analysis was used to determine occupational factors associated with mercury exposure at 95% confidence level. The mean age of the small-scale gold miners was 29.5 ±9.6 years, and 323(94.20%) were males. One hundred and sixty (46.65%) of the small-scale gold miners had urine mercury above the recommended exposure limit (mercury exposure among those who have previously worked at other small-scale gold mines (χ 2 =4.96, p=0.03). The use of personal protective equipment among the small-scale gold miners was low. Retorts, which are globally recommended for burning amalgam, were not found at mining sites. A large proportion of small-scale gold miners in Prestea were having mercury exposure in excess of occupational exposure limits, and are at risk of experiencing adverse health related complications. Ghana Environmental Protection Agency should organize training for the miners.

Smoke emissions in small-scale burning of wood

Tuomi, S.

1993-01-01

The article is based on research carried out in Finland and Sweden on the subject of emissions of smoke in the small-scale burning of wood and the factors affecting it. Due to incomplete combustion, small-scale burning of wood is particularly typified by its emissions of solid particles, carbon monoxide, hydrocarbons and PAH compounds. Included among factors influencing the volume of emissions are the load imposed on the heating device, the manner in which the fuel is fed into the firebox, fuel quality, and heating device structure. Emissions have been found to be at their minimum in connection with heating systems based on accumulators. Emissions can be significantly reduced by employing state-of-the-art technology, appropriate ways of heating and by dry fuel. A six-year bioenergy research programme was launched early in 1993 in Finland. All leading research institutions and enterprises participate in this programme. Reduction of emissions has been set as the central goal in the part dealing with small-scale burning of wood. Application of catalytic combustion in Finnish-made heating devices is one of the programmes development targets. Up to this date, the emissions produced in the small-scale burning of wood are not mentioned in official regulations pertaining to approved heating devices. In Sweden tar emissions are applied as a measure of the environmental impact imposed by heating devices

Small-scale microwave background anisotropies implied by large-scale data

Kashlinsky, A.

1993-01-01

In the absence of reheating microwave background radiation (MBR) anisotropies on arcminute scales depend uniquely on the amplitude and the coherence length of the primordial density fluctuations (PDFs). These can be determined from the recent data on galaxy correlations, xi(r), on linear scales (APM survey). We develop here expressions for the MBR angular correlation function, C(theta), on arcminute scales in terms of the power spectrum of PDFs and demonstrate their accuracy by comparing with detailed calculations of MBR anisotropies. We then show how to evaluate C(theta) directly in terms of the observed xi(r) and show that the APM data give information on the amplitude, C(O), and the coherence angle of MBR anisotropies on small scales.

Cultural life scripts are shared knowledge about the timing of important life events. In the present study, we examined whether cultural life scripts are transmitted through traditions and whether there are additional ways through which they can be attained by asking Australian and Malaysian participants which information sources they had used to generate the life script of their culture. Participants hardly reported that they had used cultural and religious traditions. They more often reported that they had used their own experiences and experiences of relatives and friends. They also reported the use of comments of relatives and friends and the use of newspapers, books, movies and television programmes. Furthermore, we examined the stability of life scripts and similarities and differences across cultures. We found that life scripts are stable cognitive structures and that there are, besides cross-cultural differences in the content, small cross-cultural differences in the valence and distribution of life script events, with the Australian life script containing more positive events and more events expected to occur before the age of 16.

2011-01-01

The IHX (intermediate heat exchanger) of a VHTR (very high-temperature reactor) is a core component that transfers the high heat generated by the VHTR at 950 .deg. C to a hydrogen production plant. Korea Atomic Energy Research Institute manufactured a small-scale prototype of a PCHE (printed circuit heat exchanger) that was being considered as a candidate for the IHX. In this study, as a part of high-temperature structural integrity evaluation of the small-scale PCHE prototype, we carried out high-temperature structural analysis modeling and macroscopic thermal and elastic structural analysis for the small-scale PCHE prototype under small-scale gas-loop test conditions. The modeling and analysis were performed as a precedent study prior to the performance test in the small-scale gas loop. The results obtained in this study will be compared with the test results for the small-scale PCHE. Moreover, these results will be used in the design of a medium-scale PCHE prototype

Sade Kampong is one of the traditional kampongs in Indonesia, which located at Rambitan Village, Lombok. Lombok has been developed for tourism activity since years ago. The Lombok Province Government has identified Tourism as one of the key drives for the economic development. Hotel resort and others hospitalities buildings have been developed to all of the areas. Nowadays, the development of Sade Cultural Kampong will therefore open up new and demand oriented products (only focus on traditional woven of Sasak). Sade Kampong should be developed as a tourism destination with appreciated and developed its heritage and traditions with sustainability concepts (with the focus on social, economic, and environmental). This paper will elaborate some local potential Sade Kampong, such as architecture, culture, and landscape as a local potential for developing a new tourism destination.

Patients from collective cultures with a tradition-bound Islamic cultural background (e.g. people from the Middle East and some Far-East countries such Pakistan and Indonesia), have a different perception of disease and different conceptions of healing, which up till now have not been sufficiently appreciated in modern multimodal therapeutic approaches and health management. Taking patients' value systems into consideration in a culture-sensitive way, with reference to their notions of magic, healing ceremonies and religious rituals and especially patterns of relations and experience in the treatment of psychological diseases in medical psychotherapeutic work, with due regard to scientific psychotherapeutic standards, can be used as an intercultural resource and lead to establishing partnership-like relationships between patients and therapists.

The production of monoclonal antibodies by mammalian cell culture in bioreactors up to 25,000 L is state of the art technology in the biotech industry. During the lifecycle of a product, several scale up activities and technology transfers are typically executed to enable the supply chain strategy of a global pharmaceutical company. Given the sensitivity of mammalian cells to physicochemical culture conditions, process and equipment knowledge are critical to avoid impacts on timelines, product quantity and quality. Especially, the fluid dynamics of large scale bioreactors versus small scale models need to be described, and similarity demonstrated, in light of the Quality by Design approach promoted by the FDA. This approach comprises an associated design space which is established during process characterization and validation in bench scale bioreactors. Therefore the establishment of predictive models and simulation tools for major operating conditions of stirred vessels (mixing, mass transfer, and shear force.), based on fundamental engineering principles, have experienced a renaissance in the recent years. This work illustrates the systematic characterization of a large variety of bioreactor designs deployed in a global manufacturing network ranging from small bench scale equipment to large scale production equipment (25,000 L). Several traditional methods to determine power input, mixing, mass transfer and shear force have been used to create a data base and identify differences for various impeller types and configurations in operating ranges typically applied in cell culture processes at manufacturing scale. In addition, extrapolation of different empirical models, e.g. Cooke et al. (Paper presented at the proceedings of the 2nd international conference of bioreactor fluid dynamics, Cranfield, UK, 1988), have been assessed for their validity in these operational ranges. Results for selected designs are shown and serve as examples of structured

Small-Scale Renewable Energy Converters for Battery Charging

2018-03-01

Full Text Available This paper presents two wave energy concepts for small-scale electricity generation. In the presented case, these concepts are installed on the buoy of a heaving, point-absorbing wave energy converter (WEC for large scale electricity production. In the studied WEC, developed by Uppsala University, small-scale electricity generation in the buoy is needed to power a tidal compensating system designed to increase the performance of the WEC in areas with high tides. The two considered and modeled concepts are an oscillating water column (OWC and a heaving point absorber. The results indicate that the OWC is too small for the task and does not produce enough energy. On the other hand, the results show that a hybrid system composed of a small heaving point absorber combined with a solar energy system would be able to provide a requested minimum power of around 37.7 W on average year around. The WEC and solar panel complement each other, as the WEC produces enough energy by itself during wintertime (but not in the summer, while the solar panel produces enough energy in the summer (but not in the winter.

Empirical spatial econometric modelling of small scale neighbourhood

Gerkman, Linda

2012-07-01

The aim of the paper is to model small scale neighbourhood in a house price model by implementing the newest methodology in spatial econometrics. A common problem when modelling house prices is that in practice it is seldom possible to obtain all the desired variables. Especially variables capturing the small scale neighbourhood conditions are hard to find. If there are important explanatory variables missing from the model, the omitted variables are spatially autocorrelated and they are correlated with the explanatory variables included in the model, it can be shown that a spatial Durbin model is motivated. In the empirical application on new house price data from Helsinki in Finland, we find the motivation for a spatial Durbin model, we estimate the model and interpret the estimates for the summary measures of impacts. By the analysis we show that the model structure makes it possible to model and find small scale neighbourhood effects, when we know that they exist, but we are lacking proper variables to measure them.

Antimicrobial use and antimicrobial susceptibility in Escherichia coli on small- and medium-scale pig farms in north-eastern Thailand

2017-07-01

Full Text Available Abstract Background Intensification of livestock production seen in many low- and middle-income countries is often believed to be associated with increased use of antimicrobials, and may hence contribute to the emergence of antimicrobial resistance. The aim of this study was to map antimicrobial use on small- (n = 25 and medium-scale (n = 27 pig farms in north-eastern Thailand, and to compare antimicrobial susceptibility of commensal Escherichia coli isolated from sows on these farms. Methods Information regarding pig husbandry and antimicrobial treatment regimens was obtained by the use of semi-structured questionnaires. Faecal samples were collected from three healthy sows at each farm, and Escherichia coli was cultured and analysed for antimicrobial susceptibility using the broth microdilution method. Multilevel regression models were used to compare antimicrobial susceptibility between isolates from small- and medium-scale farms. Results All farms included in the study administered antimicrobials to their sows. Small-scale farmers most commonly (64% decided themselves when to give antimicrobials and the majority (60% bought the medicines at the local store or pharmacy, whereas farmers on medium-scale farms always discussed antimicrobial treatment with a veterinarian. Medium-scale farms used a greater diversity of antimicrobials than small-scale farms and did also administer antimicrobials in feed to a higher extent. High levels of antimicrobial resistance to several critically important antimicrobials for human medicine (including ciprofloxacin, streptomycin and ampicillin were found in isolates from both small- and medium-scale farms. Resistance levels were significantly (P < 0.05 higher in isolates from medium-scale farms for several of the antimicrobials tested, as well as the level of multidrug-resistance (P = 0.026. Conclusion The routines regarding access and administration of antimicrobials differed between the small- and

2001-12-01

Full Text Available Marine snow aggregates are believed to be the main vehicles for vertical material transport in the ocean. However, aggregates are also sites of elevated heterotrophic activity, which may rather cause enhanced retention of aggregated material in the upper ocean. Small-scale biological-physical interactions govern the formation and fate of marine snow. Aggregates may form by physical coagulation: fluid motion causes collisions between small primary particles (e.g. phytoplankton that may then stick together to form aggregates with enhanced sinking velocities. Bacteria may subsequently solubilise and remineralise aggregated particles. Because the solubilization rate exceeds the remineralization rate, organic solutes leak out of sinking aggregates. The leaking solutes spread by diffusion and advection and form a chemical trail in the wake of the sinking aggregate that may guide small zooplankters to the aggregate. Also, suspended bacteria may enjoy the elevated concentration of organic solutes in the plume. I explore these small-scale formation and degradation processes by means of models, experiments and field observations. The larger scale implications for the structure and functioning of pelagic food chains of export vs. retention of material will be discussed.

The challenges of biofuels from the perspective of small-scale producers in Ohio

International Nuclear Information System (INIS)

Morrone, Michele; Stuart, Ben J.; McHenry, Izaak; Buckley, Geoffrey L.

2009-01-01

Increased interest in renewable fuels in the United States, such as biodiesel and ethanol, is mainly the result of higher cost for traditional fuels after years of low prices. A growing concern over oil imports from politically unstable parts of the world has also led people to seriously consider alternatives to gasoline. Despite this attention, there are issues that challenge the widespread acceptance of biofuels, including the availability of raw materials and food security concerns. Ohio is one of the most productive agricultural states in the country, able to contribute significant amounts of corn and soybeans, the main feedstock for biofuels. Even though Ohio is rich in the raw materials needed for biofuel production, it is still an endeavor that mainly involves small businesses that face numerous challenges. Some of these challenges are national in scope, while others are localized. Interviews with small-scale biofuels producers in Ohio identify some of the major political, economic, and perceptual hurdles confronting this fledgling industry

Bahauddin Azizi

2014-01-01

Full Text Available This paper dwells into heritage tourism that is related to the architectural and cultural heritage of the Rungus people of Sabah, Malaysian Borneo. It investigates the cultural influence on the architecture of the longhouse. The Rungus tribal group can be found in the northeast corner of Sabah, farming the land mostly on agricultural products in small scale plantations. Their longhouses, facing extinction, are dual-purpose dwellings, constructed entirely of traditional materials utilising small split timbers lashed with rattan for the frame, palm fronds for the thatched roof, split bamboo for the floor and tree bark of hewn wood for the compartment walls. Each family has its own separate quarters off a common hall for socialising and community work and village life is usually based on the cultural traditions. Strongly related to the spirit of the place, the ‘rice spirit’, in particular, figures prominently in the Rungus people’s beliefs and practices in controlling the spirits and the people’s daily life and often governed by the words of the bobohizans, the high priestess. The objectives gear towards analysing the architectural values and investigating cultural understanding associated with the longhouses. Most importantly, the issue of how the Rungus people relate to the environment is studied through the tangible and intangible cultural aspects of the people. The research utilises the observation technique, interviews with the residents, visual data collection and measured drawings of five longhouses as the processes to document data. The paper instigates an investigation into the conformity of the Rungus people of their place in the environment to perpetuate their lifestyle blessed with a unique heritage found in their architecture and culture, in a land where nature reigns. It is a heritage that worth a second look in the tourism industry of Sabah.

2016-01-01

Full Text Available Small scale mining continues to contribute significantly to the growth of Ghana's economy. However, the sector poses serious dangers to human health and the environment. Ground failures resulting from poorly supported stopes have led to injuries and fatalities in recent times. Dust and fumes from drilling and blasting of ore present health threats due to poor ventilation. Four prominent small scale underground mines were studied to identify the safety issues associated with small scale underground mining in Ghana. It is recognized that small scale underground mining in Ghana is inundated with unsafe acts and conditions including stope collapse, improper choice of working tools, absence of personal protective equipment and land degradation. Inadequate monitoring of the operations and lack of regulatory enforcement by the Minerals Commission of Ghana are major contributing factors to the environmental, safety and national security issues of the operations.

2014-01-01

The purpose of this paper is to describe the theoretical development and initial validation of the newly developed Work-Life Balance Culture Scale (WLBCS), an instrument for measuring an organizational culture that promotes the work-life balance of employees. In Study 1 (N=498), the scale was developed and its factorial validity tested through exploratory factor analyses. In Study 2 (N=513), confirmatory factor analysis (CFA) was performed to examine model fit and retest the dimensional structure of the instrument. To assess construct validity, a priori hypotheses were formulated and subsequently tested using correlation analyses. Exploratory and confirmatory factor analyses revealed a one-factor model. Results of the bivariate correlation analyses may be interpreted as preliminary evidence of the scale's construct validity. The five-item WLBCS is a new and efficient instrument with good overall quality. Its conciseness makes it particularly suitable for use in employee surveys to gain initial insight into a company's perceived work-life balance culture.

To develop a version of the modified Japanese Orthopaedic Association (mJOA) scale that had been translated into Portuguese and cross-culturally adapted for the Brazilian population. The well-established process of forward-backward translation was employed along with cross-cultural adaptation. Three bilingual translators (English and native Portuguese) performed the forward translation of the mJOA scale from English to Portuguese based on iterative discussions used to reach a consensus translation. The translated version of the mJOA scale was then back-translated into English by a native English-speaking translator unaware of the concepts involved with the mJOA scale. The original mJOA scale and the back-translated version were compared by a native North American neurosurgeon, and as they were considered equivalent, the final version of the mJOA scale that had been translated into Portuguese and cross-culturally adapted was defined. To facilitate global and cross-cultural comparisons of the severity of cervical myelopathy, this study presents a version of the mJOA scale that was translated into Portuguese and cross-culturally adapted for the Brazilian population.

2015-03-01

Full Text Available The role of value of privacy in shaping Iranian culture is vital. In contrary to modern middle-class Iranian high density vertical development housing, this cultural principle plays a great role in shaping spatial organization of Iranian traditional housing. The aim of this study is to establish a framework to improve spatial organization of modern Iranian high density vertical development (HDVD housing through lessons learnt from traditional Iranian housing. In this regard, to reach the aim through qualitative approach and case study strategy, this value of the Iranian traditional housing was investigated. The data collection methods to collect data from middle-class traditional and modern high-density vertical development (HDVD housing, were multiple tactics as direct observation, open-ended expert interview, semi-structured and focus group interviewing, taking photo, and plan layout. As conclude, it was reached that privacy as a principle governing all aspects of life has had deep impacts on spatial organization of traditional Iranian housing. Thus through using the spatial concept of privacy learnt from traditional Iranian housing can formulate recommendations to betterment spatial organization of middle-class modern Iranian HDVD housing.

Large-scale production of lentiviral vector in a closed system hollow fiber bioreactor

Directory of Open Access Journals (Sweden)

Jonathan Sheu

Full Text Available Lentiviral vectors are widely used in the field of gene therapy as an effective method for permanent gene delivery. While current methods of producing small scale vector batches for research purposes depend largely on culture flasks, the emergence and popularity of lentiviral vectors in translational, preclinical and clinical research has demanded their production on a much larger scale, a task that can be difficult to manage with the numbers of producer cell culture flasks required for large volumes of vector. To generate a large scale, partially closed system method for the manufacturing of clinical grade lentiviral vector suitable for the generation of induced pluripotent stem cells (iPSCs, we developed a method employing a hollow fiber bioreactor traditionally used for cell expansion. We have demonstrated the growth, transfection, and vector-producing capability of 293T producer cells in this system. Vector particle RNA titers after subsequent vector concentration yielded values comparable to lentiviral iPSC induction vector batches produced using traditional culture methods in 225 cm2 flasks (T225s and in 10-layer cell factories (CF10s, while yielding a volume nearly 145 times larger than the yield from a T225 flask and nearly three times larger than the yield from a CF10. Employing a closed system hollow fiber bioreactor for vector production offers the possibility of manufacturing large quantities of gene therapy vector while minimizing reagent usage, equipment footprint, and open system manipulation.

Small scale wood combustion in Germany. Recent research and trends

1998-12-31

To reduce Europe`s greenhouse gas emission CO{sub 2} it is a challenging task utilising biomass fuels as there are wood or wood residues from the forest industry. The utilisation can be done either in commercially operated medium (> 50 kWth) or full scale (> 1 MWth) decentralised heat and power stations or in small scale (< 50 kWth) domestic heating systems. In small scale heating systems untreated wood logs, wood briquette or wood pellets and in few cases wood chips are used. The present market in Germany is focused on the use of wood logs. Presently, the use of wood pellets in small scale automatically operated boilers < 15 kW especially for low energy houses is discussed more and more. Since 1980 the installation of new wood fired small scale domestic heating systems reached a significant size due to the interest of the customers to have a alternative inhouse heating system and to increase the living comfort. In 1994 the amount of sold small scale heaters in Germany were in total about 133.258 units. The thermal power of in 1994 sold units is estimated of about 1350 MW which is a significant size in total with regard to domestic heating purposes. Since few years there is a clear market trend in Germany towards the installation of open fire stoves. Due to this trend in Germany and the design characteristic of open fire stoves using huge glass doors of glass windows it is very difficult to achieve a further reduction of emissions like CO and unburned volatile hydrocarbons (VOC). In the text the requirements for modern small scale wood fired stoves in Germany as well as the actual stage and trend of research and development (R and D) are discussed 4 refs.

Low relative error in consumer-grade GPS units make them ideal for measuring small-scale animal movement patterns

Directory of Open Access Journals (Sweden)

Greg A. Breed

2015-08-01

Full Text Available Consumer-grade GPS units are a staple of modern field ecology, but the relatively large error radii reported by manufacturers (up to 10 m ostensibly precludes their utility in measuring fine-scale movement of small animals such as insects. Here we demonstrate that for data collected at fine spatio-temporal scales, these devices can produce exceptionally accurate data on step-length and movement patterns of small animals. With an understanding of the properties of GPS error and how it arises, it is possible, using a simple field protocol, to use consumer grade GPS units to collect step-length data for the movement of small animals that introduces a median error as small as 11 cm. These small error rates were measured in controlled observations of real butterfly movement. Similar conclusions were reached using a ground-truth test track prepared with a field tape and compass and subsequently measured 20 times using the same methodology as the butterfly tracking. Median error in the ground-truth track was slightly higher than the field data, mostly between 20 and 30 cm, but even for the smallest ground-truth step (70 cm, this is still a signal-to-noise ratio of 3:1, and for steps of 3 m or more, the ratio is greater than 10:1. Such small errors relative to the movements being measured make these inexpensive units useful for measuring insect and other small animal movements on small to intermediate scales with budgets orders of magnitude lower than survey-grade units used in past studies. As an additional advantage, these units are simpler to operate, and insect or other small animal trackways can be collected more quickly than either survey-grade units or more traditional ruler/gird approaches.

Passive Plasma Contact Mechanisms for Small-Scale Spacecraft

Science.gov (United States)

McTernan, Jesse K.

Small-scale spacecraft represent a paradigm shift in how entities such as academia, industry, engineering firms, and the scientific community operate in space. However, although the paradigm shift produces unique opportunities to build satellites in unique ways for novel missions, there are also significant challenges that must be addressed. This research addresses two of the challenges associated with small-scale spacecraft: 1) the miniaturization of spacecraft and associated instrumentation and 2) the need to transport charge across the spacecraft-environment boundary. As spacecraft decrease in size, constraints on the size, weight, and power of on-board instrumentation increase--potentially limiting the instrument's functionality or ability to integrate with the spacecraft. These constraints drive research into mechanisms or techniques that use little or no power and efficiently utilize existing resources. One limited resource on small-scale spacecraft is outer surface area, which is often covered with solar panels to meet tight power budgets. This same surface area could also be needed for passive neutralization of spacecraft charging. This research explores the use of a transparent, conductive layer on the solar cell coverglass that is electrically connected to spacecraft ground potential. This dual-purpose material facilitates the use of outer surfaces for both energy harvesting of solar photons as well as passive ion collection. Mission capabilities such as in-situ plasma measurements that were previously infeasible on small-scale platforms become feasible with the use of indium tin oxide-coated solar panel coverglass. We developed test facilities that simulate the space environment in low Earth orbit to test the dual-purpose material and the various application of this approach. Particularly, this research is in support of two upcoming missions: OSIRIS-3U, by Penn State's Student Space Programs Lab, and MiTEE, by the University of Michigan. The purpose of

Assessing the Efficiency of Small-Scale and Bottom Trawler Vessels in Greece

Directory of Open Access Journals (Sweden)

Dario Pinello

2016-07-01

Full Text Available This study explores the technical and scale efficiency of two types of Greek fishing vessels, small-scale vessels and bottom trawlers, using a bias-corrected input-oriented Data Envelopment Analysis model. Moreover, the associations between efficiency scores and vessel’s and skipper’s characteristics are also explored. The results indicate that small-scale vessels achieve a very low average technical efficiency score (0.42 but a much higher scale efficiency score (0.81. Conversely, bottom trawlers achieve lower scale but higher technical efficiency scores (0.68 and 0.73, respectively. One important finding of this study is that the technical efficiency of small-scale vessels, in contrast to trawlers, is positively associated with the experience of the skipper. In a looser context, it can be said that small-scale fisheries mainly rely on skill, whereas bottom trawlers rely more on technology. This study concludes that there is space for improvement in efficiency, mainly for small-scale vessels, which could allow the achievement of the same level of output by using reduced inputs.

Impact of small-scale structures on estuarine circulation

2018-05-01

We present a novel and challenging application of a 3D estuary-shelf model to the study of the collective impact of many small-scale structures (bridge pilings of 1 m × 2 m in size) on larger-scale circulation in a tributary (James River) of Chesapeake Bay. We first demonstrate that the model is capable of effectively transitioning grid resolution from 400 m down to 1 m near the pilings without introducing undue numerical artifact. We then show that despite their small sizes and collectively small area as compared to the total channel cross-sectional area, the pilings exert a noticeable impact on the large-scale circulation, and also create a rich structure of vortices and wakes around the pilings. As a result, the water quality and local sedimentation patterns near the bridge piling area are likely to be affected as well. However, when evaluating over the entire waterbody of the project area, the near field effects are weighed with the areal percentage which is small compared to that for the larger unaffected area, and therefore the impact on the lower James River as a whole becomes relatively insignificant. The study highlights the importance of the use of high resolution in assessing the near-field impact of structures.

Some Aspects of Culture Teaching in Foreign Language and ESP Classes: Cultural Scripts and Small Talk

Directory of Open Access Journals (Sweden)

Ivona Baranovskaja

2011-12-01

Full Text Available The present paper deals with the problem of teaching culture in the foreign language classes at all levels of education. Cultural studies should not be separated from the language syllabus and foreign language learning should not be limited to formal learning of systems of sounds, words, and syntactic structures, but should also include learning the culture of the target language. Success in intercultural communication depends greatly on the understanding of a number of cultural features. The article emphasizes the importance of teaching and learning target culture, as well as introduces the analysis of cultural scripts and small talk in English, Russian and Polish languages. Understanding the cultural differences will benefit and facilitate cross-cultural communication under diverse circumstances. Thereby, this issue is relevant to foreign language and ESP classes focusing on the improvement of both students’ language and cultural skills.

Bham, Zaheerah; Ross, Eleanor

2005-01-01

To investigate the beliefs of caregivers and traditional healers within the South African Indian Muslim community regarding the etiology and treatment of stroke and the persons likely to be consulted in this regard. A descriptive case study design was employed which incorporated two groups and was located within a qualitative paradigm. Data were collected within the homes of caregivers and the consulting rooms of traditional healers. Ten caregivers of persons who had sustained strokes and 10 traditional healers were interviewed. Individual interviews were held with participants. Responses to semi-structured interview schedules were analyzed using thematic content analysis and descriptive statistics. For both groups, religion and faith in God played a pertinent role in beliefs regarding etiology of illnesses such as stroke. Caregivers used a combination of traditional and Western medicine approaches. For traditional healers, treatment was based on the premise of restoring the balance between hot and cold in the body, which had been placed in disequilibrium by the stroke. Participants expressed disillusionment with referrals to Western healthcare professionals whose treatment was often regarded as culturally inappropriate. They also emphasized the integral role played by family members in the treatment of illness and disease. Results have implications for: culturally sensitive management of stroke patients in the South African Indian Muslim community; collaboration between Western and traditional healers; involvement of families in the remediation process; and further research.

With the globalization and rapid development every filed is taking an increasing interest in physical geography and human economics. There is a surging demand for small scale world map in large formats all over the world. Further study of automated mapping technology, especially the realization of small scale production on a large scale global map, is the key of the cartographic field need to solve. In light of this, this paper adopts the improved model (with the map and data separated) in the field of the mapmaking generalization, which can separate geographic data from mapping data from maps, mainly including cross-platform symbols and automatic map-making knowledge engine. With respect to the cross-platform symbol library, the symbol and the physical symbol in the geographic information are configured at all scale levels. With respect to automatic map-making knowledge engine consists 97 types, 1086 subtypes, 21845 basic algorithm and over 2500 relevant functional modules.In order to evaluate the accuracy and visual effect of our model towards topographic maps and thematic maps, we take the world map generalization in small scale as an example. After mapping generalization process, combining and simplifying the scattered islands make the map more explicit at 1 : 2.1 billion scale, and the map features more complete and accurate. Not only it enhance the map generalization of various scales significantly, but achieve the integration among map-makings of various scales, suggesting that this model provide a reference in cartographic generalization for various scales.

Small-Scale Spray Releases: Additional Aerosol Test Results

One of the events postulated in the hazard analysis at the Waste Treatment and Immobilization Plant (WTP) and other U.S. Department of Energy (DOE) nuclear facilities is a breach in process piping that produces aerosols with droplet sizes in the respirable range. The current approach for predicting the size and concentration of aerosols produced in a spray leak involves extrapolating from correlations reported in the literature. These correlations are based on results obtained from small engineered spray nozzles using pure liquids with Newtonian fluid behavior. The narrow ranges of physical properties on which the correlations are based do not cover the wide range of slurries and viscous materials that will be processed in the WTP and across processing facilities in the DOE complex. To expand the data set upon which the WTP accident and safety analyses were based, an aerosol spray leak testing program was conducted by Pacific Northwest National Laboratory (PNNL). PNNL’s test program addressed two key technical areas to improve the WTP methodology (Larson and Allen 2010). The first technical area was to quantify the role of slurry particles in small breaches where slurry particles may plug the hole and prevent high-pressure sprays. The results from an effort to address this first technical area can be found in Mahoney et al. (2012a). The second technical area was to determine aerosol droplet size distribution and total droplet volume from prototypic breaches and fluids, including sprays from larger breaches and sprays of slurries for which literature data are largely absent. To address the second technical area, the testing program collected aerosol generation data at two scales, commonly referred to as small-scale and large-scale. The small-scale testing and resultant data are described in Mahoney et al. (2012b) and the large-scale testing and resultant data are presented in Schonewill et al. (2012). In tests at both scales, simulants were used to mimic the

Traditional llama husbandry and breeding management in the Ayopaya region, Bolivia.

The llama claims the largest population of the domestic South American camelids, most of which are raised in Bolivia. More than 53,000 rural families are dedicated to llama husbandry as part of their livelihood strategy. Contemporary Andean societies deliberately select animals for specific traits and employ substantial livestock management to secure subsistence. This study presents traditional llama husbandry and breeding management activities in the Ayopaya region, Bolivia. Traditional selection traits for male and female llamas are documented and assessed by a ranking and a ratio-scaled evaluation. Husbandry and management parameters are in concordance with other studies conducted in the region, but show a high variation. Average llama herd sizes are rather small (mu = 45.6). In some herds, breeding males are utilized for a long time and mix with other herds, causing concerns about inbreeding. Preferred trait groups for llama males according to farmers' responses were body conformation, fibre, testicle conformation, fleece colour and height at withers. Traditional selection criteria generally relate to the phenotype, but also include the commercially interesting fibre trait. The presented results should be considered in breeding and management programmes for the respective llama population to ensure sustainable use of this genetically and culturally valuable resource.

New markets for small-scale hydro

Maurer, E.A.

1997-01-01

The market for small and medium sized hydro-electric power plant is more attractive than ever. The boom in Europe has increasingly spread to the emerging countries, and here too small hydro plays an important ecological role. In addition to new plant rehabilitation of 'historical' plant is now a major factor. The last few years have seen a market shift from single machine components to complete plant and systems, requiring a strategy re-think on the part of larger companies. Following the influx of private capital into the power industry, business conditions have also undergone a thorough transformation. In place of 'fast money', hydro power offers the prospect of earning longer-term, sustainable money'. The term small-scale hydro-electric power (or simply 'small hydro') is used slightly differently depending on the country and market. Here, it is used to denote plant with turbines up to 10 MW.

Kitaplioglu, Cahit

1990-01-01

Rotor hover-performance data from a 1/6-scale helicopter rotor are analyzed and the data sets compared for the effects of ambient wind, test stand configuration, differing test facilities, and scaling. The data are also compared to full scale hover data. The data exhibited high scatter, not entirely due to ambient wind conditions. Effects of download on the test stand proved to be the most significant influence on the measured data. Small-scale data correlated resonably well with full scale data; the correlation did not improve with Reynolds number corrections.

2014-02-01

Descriptions of culture change adoption are often complex and varied, creating a challenge for those seeking guidance about which of the many components of culture change to adopt and in what order and combination. To begin to address this question, members of The Research Initiative Valuing Eldercare (THRIVE) developed and distributed an online survey to 327 known culture change adopters. Of these, 164 (50%) completed the survey. Data were analyzed to identify adopted components, co-occurrence of adopted components, and differences in these across various types of nursing home models (i.e., traditional unit, household, and small house). Our findings support unique co-occurrence of components across nursing home models. Results also show that homes with more traditional environments have been able to implement certain culture change components without large capital investments required by renovations. The adoption patterns suggest that the co-occurrence of components should be considered when pursuing organizational transformations to support culture change.

Small-scale magnetic holes (MHs), local depletions in magnetic field strength, have been observed multiple times in the Earths magnetosphere in the bursty bulk flow (BBF) braking region. This particular subset of MHs has observed scale sizes perpendicular to the background magnetic field (B) less than the ambient ion Larmor radius (p(sib i)). Previous observations by Time History of Events and Macroscale Interactions during Substorms (THEMIS) indicate that this subset of MHs can be supported by a current driven by the E x B drift of electrons. Ions do not participate in the E x B drift due to the small-scale size of the electric field. While in the BBF braking region, during its commissioning phase, the Magnetospheric Multiscale (MMS) spacecraft observed a small-scale MH. The electric field observations taken during this event suggest the presence of electron currents perpendicular to the magnetic field. These observations also suggest that these currents can evolve to smaller spatial scales.

To the rescue of traditions: Emotional Design and Cultural Values, A Case Study Based on Barranquilla´s Carnival

Full Text Available Heritage, as a cultural expression, refers to a set of tangible and intangible assets that certain groups of individuals use to express themselves. Design is part of these productions that empower objects and create emotional bonds between people and their culture. "The Guacherna: Funny dolls" is a collection of characters inspired in Barranquilla´s Carnival that focuses on the relation between cultural and symbolic values as raw material for emotional design. Throughout this process, it was found that narrative as derived from traditions, as the carnival encourages and strengthens emotional bonds between people and objects, opens possibilities for these traditions to be renewed, divulged, and helps them remain alive in the memory.

In this paper we study the small-world network model of Watts and Strogatz, which mimics some aspects of the structure of networks of social interactions. We argue that there is one nontrivial length-scale in the model, analogous to the correlation length in other systems, which is well-defined in the limit of infinite system size and which diverges continuously as the randomness in the network tends to zero, giving a normal critical point in this limit. This length-scale governs the crossover from large- to small-world behavior in the model, as well as the number of vertices in a neighborhood of given radius on the network. We derive the value of the single critical exponent controlling behavior in the critical region and the finite size scaling form for the average vertex-vertex distance on the network, and, using series expansion and Pade approximants, find an approximate analytic form for the scaling function. We calculate the effective dimension of small-world graphs and show that this dimension varies as a function of the length-scale on which it is measured, in a manner reminiscent of multifractals. We also study the problem of site percolation on small-world networks as a simple model of disease propagation, and derive an approximate expression for the percolation probability at which a giant component of connected vertices first forms (in epidemiological terms, the point at which an epidemic occurs). The typical cluster radius satisfies the expected finite size scaling form with a cluster size exponent close to that for a random graph. All our analytic results are confirmed by extensive numerical simulations of the model. (c) 1999 The American Physical Society.

Full Text Available Africa is a multicultural continent with a large variety of sociopolitical situations. All along the continent there is a common characteristic based on traditional culture: women’s reproductive role is the basis of social and economic structure. Women’s infertility implies an important stigma which has a great personal, familiar and social impact. I study the incidence, causes and consequences of sub-Saharan women’s infertility. I also analyze the different therapeutic approaches, feasibility of new reproductive techniques for the general population in their real lives and the bioethics discussion this involves.

Degradation mechanisms of small scale piping systems

Bartonicek, J.; Koenig, G.; Blind, D.

1996-01-01

Operational experience shows that many degradation mechanisms can have an effect on small-scale piping systems. We can see from the analyses carried out that the degradation which has occurred is primarily linked with the fact that these piping systems were classified as being of low safety relevance. This is mainly due to such components being classified into low safety relevance category at the design stage, as well as to the low level of operational monitoring. Since in spite of the variety of designs and operational modes the degradation mechanisms detected may be attributed to the piping systems, we can make decisive statements on how to avoid such degradation mechanisms. Even small-scale piping systems may achieve guaranteed integrity in such cases by taking the appropriate action. (orig.) [de

Validity of thermally-driven small-scale ventilated filling box models

Partridge, Jamie L.; Linden, P. F.

2013-11-01

The majority of previous work studying building ventilation flows at laboratory scale have used saline plumes in water. The production of buoyancy forces using salinity variations in water allows dynamic similarity between the small-scale models and the full-scale flows. However, in some situations, such as including the effects of non-adiabatic boundaries, the use of a thermal plume is desirable. The efficacy of using temperature differences to produce buoyancy-driven flows representing natural ventilation of a building in a small-scale model is examined here, with comparison between previous theoretical and new, heat-based, experiments.

Philippines: Small-scale renewable energy update

NONE

1997-12-01

This paper gives an overview of the application of small scale renewable energy sources in the Philippines. Sources looked at include solar, biomass, micro-hydroelectric, mini-hydroelectric, wind, mini-geothermal, and hybrid. A small power utilities group is being spun off the major utility, to provide a structure for developing rural electrification programs. In some instances, private companies have stepped forward, avoiding what is perceived as overwhelming beaurocracy, and installed systems with private financing. The paper provides information on survey work which has been done on resources, and the status of cooperative programs to develop renewable systems in the nation.

2017-02-01

Full Text Available The rise of supermarkets in Indonesia since the end of the 1990s have been transforming the food retail sector and providing further market opportunities for small-scale farmers, in which most of Indonesia’s farmer falls into this category. The aim of this paper is to examine the supermarket participation and its effect on the well-being of small-scale farmers. We compare the differences between participants and non-participants in supermarket channels in order to explore the constraints on supermarket participation. By applying a treatment effects model which allows capturing the possibility of selection bias, we examine the factors that determine farmers’ participation as well as the effect on their income. The results show that younger farmers with higher levels of education, irrigated land, who have packaging equipment and storage facilities, and are located near paved roads, are more likely to participate in the supermarket channels. On the other hand, farmers who have sprayer equipment are more likely to participate in the traditional market channels. The effect analysis shows that small-scale farmer participation in the supermarket channels can boost their income.

CO2-impacts of a small-scale consumers levy

International Nuclear Information System (INIS)

1995-02-01

Because of a number of developments (altered budgets of Dutch ministries and implementation of environmental policy plans of energy distribution companies in the Netherlands) the 1993 analyses of the effects of a small-scale consumer levy on the emission of CO 2 are updated. First, attention is paid to the conservation impetus as a result of an increase of the energy price for small-scale consumers. Next, the effects that can occur as a consequence of the presently suggested form of the levy (in particular, the exemption of renewable energy and waste heat) are discussed. Subsequently, the alterations of other policy tools, that are necessary in case a higher effectiveness of conservation measures is realized, are dealt with. The direct effect of a higher energy price on the saving behavior of the small-scale consumers is calculated by means of the CENECA-model. 4 tabs., 1 appendix, 8 refs

A carbon dioxide stripping model for mammalian cell culture in manufacturing scale bioreactors.

Control of carbon dioxide within the optimum range is important in mammalian bioprocesses at the manufacturing scale in order to ensure robust cell growth, high protein yields, and consistent quality attributes. The majority of bioprocess development work is done in laboratory bioreactors, in which carbon dioxide levels are more easily controlled. Some challenges in carbon dioxide control can present themselves when cell culture processes are scaled up, because carbon dioxide accumulation is a common feature due to longer gas-residence time of mammalian cell culture in large scale bioreactors. A carbon dioxide stripping model can be used to better understand and optimize parameters that are critical to cell culture processes at the manufacturing scale. The prevailing carbon dioxide stripping models in literature depend on mass transfer coefficients and were applicable to cell culture processes with low cell density or at stationary/cell death phase. However, it was reported that gas bubbles are saturated with carbon dioxide before leaving the culture, which makes carbon dioxide stripping no longer depend on a mass transfer coefficient in the new generation cell culture processes characterized by longer exponential growth phase, higher peak viable cell densities, and higher specific production rate. Here, we present a new carbon dioxide stripping model for manufacturing scale bioreactors, which is independent of carbon dioxide mass transfer coefficient, but takes into account the gas-residence time and gas CO 2 saturation time. The model was verified by CHO cell culture processes with different peak viable cell densities (7 to 12 × 10 6  cells mL -1 ) for two products in 5,000-L and 25,000-L bioreactors. The model was also applied to a next generation cell culture process to optimize cell culture conditions and reduce carbon dioxide levels at manufacturing scale. The model provides a useful tool to understand and better control cell culture carbon dioxide

A novel dried bacterial consortium of Lactobacillus rhamnosus yoba 2012 and Streptococcus thermophilus C106 is cultured in 1 L of milk. This fresh starter can be used for the production of fermented milk and other fermented foods either at home or at small-scale in rural settings. For the fresh starter, 1 L of milk is pasteurized in a pan that fits into a larger pan containing water, placed on a source of heat. In this water bath, the milk is heated and incubated at 85 °C for 30 min. Thereafter, the milk is cooled down to 45 °C, transferred to a vacuum flask, inoculated with the dried bacteria and left for at least 16 hr between 30 °C and 45 °C. For the purpose of frequent home production, the fresh starter is frozen into ice cubes, which can be used for the production of small volumes of up to 2 L of fermented milk. For the purpose of small-scale production in resource-poor countries, pasteurization of up to 100 L of milk is conducted in milk cans that are placed in a large sauce pan filled with water and heated on a fire at 85 °C for 30 min, and subsequently cooled to 45 °C. Next, the 100 L batch is inoculated with the 1 L freshly prepared starter mentioned before. To assure an effective fermentation at a temperature between 30 and 45 °C, the milk can is covered with a blanket for 12 hr. For the production of non-dairy fermented foods, the fresh starter is left in a cheese cloth for 12 hr, and the drained-off whey can be subsequently used for the inoculation of a wide range of food raw materials, including vegetables and cereal-based foods.

Small-scale habitat structure modulates the effects of no-take marine reserves for coral reef macroinvertebrates.

Directory of Open Access Journals (Sweden)

Pascal Dumas

Full Text Available No-take marine reserves are one of the oldest and most versatile tools used across the Pacific for the conservation of reef resources, in particular for invertebrates traditionally targeted by local fishers. Assessing their actual efficiency is still a challenge in complex ecosystems such as coral reefs, where reserve effects are likely to be obscured by high levels of environmental variability. The goal of this study was to investigate the potential interference of small-scale habitat structure on the efficiency of reserves. The spatial distribution of widely harvested macroinvertebrates was surveyed in a large set of protected vs. unprotected stations from eleven reefs located in New Caledonia. Abundance, density and individual size data were collected along random, small-scale (20×1 m transects. Fine habitat typology was derived with a quantitative photographic method using 17 local habitat variables. Marine reserves substantially augmented the local density, size structure and biomass of the target species. Density of Trochus niloticus and Tridacna maxima doubled globally inside the reserve network; average size was greater by 10 to 20% for T. niloticus. We demonstrated that the apparent success of protection could be obscured by marked variations in population structure occurring over short distances, resulting from small-scale heterogeneity in the reef habitat. The efficiency of reserves appeared to be modulated by the availability of suitable habitats at the decimetric scale ("microhabitats" for the considered sessile/low-mobile macroinvertebrate species. Incorporating microhabitat distribution could significantly enhance the efficiency of habitat surrogacy, a valuable approach in the case of conservation targets focusing on endangered or emblematic macroinvertebrate or relatively sedentary fish species.

Small scale structure formation in chameleon cosmology

International Nuclear Information System (INIS)

Brax, Ph.; Bruck, C. van de; Davis, A.C.; Green, A.M.

2006-01-01

Chameleon fields are scalar fields whose mass depends on the ambient matter density. We investigate the effects of these fields on the growth of density perturbations on sub-galactic scales and the formation of the first dark matter halos. Density perturbations on comoving scales R<1 pc go non-linear and collapse to form structure much earlier than in standard ΛCDM cosmology. The resulting mini-halos are hence more dense and resilient to disruption. We therefore expect (provided that the density perturbations on these scales have not been erased by damping processes) that the dark matter distribution on small scales would be more clumpy in chameleon cosmology than in the ΛCDM model

2017-06-01

The mandatory of biodiesel application at 20% blending (B20) has been started since January 2016. It creates huge market for biodiesel industry. To build large-scale biodiesel plant (> 100,000 tons/year) is most favorable for biodiesel producers since it can give lower production cost. This cost becomes a challenge for small - medium scale biodiesel plants. However, current biodiesel plants in Indonesia are located mainly in Java and Sumatra, which then distribute biodiesel around Indonesia so that there is an additional cost for transportation from area to area. This factor becomes an opportunity for the small - medium scale biodiesel plants to compete with the large one. This paper discusses the profitability of small - medium scale biodiesel plants conducted on a capacity of 50 tons/day using CPO and its derivatives. The study was conducted by performing economic analysis between scenarios of biodiesel plant that using raw material of stearin, PFAD, and multi feedstock. Comparison on the feasibility of scenarios was also conducted on the effect of transportation cost and selling price. The economic assessment shows that profitability is highly affected by raw material price so that it is important to secure the source of raw materials and consider a multi-feedstock type for small - medium scale biodiesel plants to become a sustainable plant. It was concluded that the small - medium scale biodiesel plants will be profitable and sustainable if they are connected to palm oil mill, have a captive market, and are located minimally 200 km from other biodiesel plants. The use of multi feedstock could increase IRR from 18.68 % to 56.52 %.

Lampung is one area in Indonesia which has a traditional culture that comes from two groups of descents, they are ulun Lampung Pepadun and ulun Lampung Saibatin. Lampungnese traditional culture has been well-known by Indonesian people for its traditional dances, traditional clothing, or traditional home architecture. However, Lampungnese traditional home garden recently may not yet been described. Information related to Lampungnese traditional home garden is still very limited and it does not yet represented the culture based design concept. This research was directed to identify the elements of the home garden and map it into design concept of the Lampungnese traditional home garden based on information of Lampungnese traditional culture. The study was conducted by using descriptive approach through literature review, interviews and cultural exploration, as well as field observation. The study was able to identify the elements forming the Lampungnese traditional home garden, namely gakhang hadap, walai, outdoor kitchenette, firewood place, outdoor kitchen, livestock barns, as well as plants. Space layout of the home garden comprises front yard (tengahbah/terambah/beruan), side yard (kebik/kakebik), and backyard (kudan/juyu/kebon). Each element of the garden is located in the right place of the space layout.

We discuss perturbative evolution of the polarized structure function g 1 in the (x, Q 2 ) plane, with special regard to the small-x region. We determine g 1 in terms of polarized quark and gluon distributions using coefficient functions to order α s . At small x g 1 then displays substantial scale dependence, which necessarily implies a corresponding scale dependence in the large-x region. This scale dependence has significant consequences for the extraction of the first moment from the experimental data, reducing its value while increasing the error. Conversely, the scale dependence may be used to constrain the size of the polarized gluon distribution. ((orig.))

Objectives This study examines the association between cultural orientation and drinking behaviors among university students. Cultural orientation is the measure of how the cultural values of individuals living in their own society are influenced by cultural values introduced from the outside. Methods In 2011, a cross-sectional survey collected data from 1279 university students from six universities in central China. Participants used a likert scale to rank a series of statements reflecting cultural values from the previously validated Chinese Cultural Orientation Scale and answered questions about their drinking behaviors and socio-demographic characteristics. Results Statistically significant differences in cultural orientation were observed for gender, hometown and type of university attendance. Traditional-oriented students were more likely to be occasional drinkers or nondrinkers, while marginal-oriented students, bicultural-oriented students and western-oriented students were more likely to be regular drinkers. Bicultural orientation (OR = 1.80, Pstudent being regular drinking, compared to students with traditional orientations. Males (OR = 4.40, Pstudents (OR = 2.59, Pstudents from urban areas (OR = 1.79, Pstudents attending key universities (OR = 0.48, Pattending general universities. Conclusions Cultural orientation influences drinking behaviors. Traditional cultural orientation was associated with less drinking while western cultural orientation, marginal cultural orientation and bicultural orientation were associated with more drinking. The role of gender, hometown and university attendance is partially moderated through the influence of cultural orientation. The relationship between a traditional cultural orientation and alcohol drinking suggests that traditional Chinese cultural values should be examined for their role in possibly reducing alcohol-related risks through education and policy initiatives.

Fractal properties and small-scale structure of cosmic string networks

International Nuclear Information System (INIS)

Martins, C.J.A.P.; Shellard, E.P.S.

2006-01-01

We present results from a detailed numerical study of the small-scale and loop production properties of cosmic string networks, based on the largest and highest resolution string simulations to date. We investigate the nontrivial fractal properties of cosmic strings, in particular, the fractal dimension and renormalized string mass per unit length, and we also study velocity correlations. We demonstrate important differences between string networks in flat (Minkowski) spacetime and the two very similar expanding cases. For high resolution matter era network simulations, we provide strong evidence that small-scale structure has converged to 'scaling' on all dynamical length scales, without the need for other radiative damping mechanisms. We also discuss preliminary evidence that the dominant loop production size is also approaching scaling

Energy transfers and magnetic energy growth in small-scale dynamo

KAUST Repository

Kumar, Rohit Raj

2013-12-01

In this letter we investigate the dynamics of magnetic energy growth in small-scale dynamo by studying energy transfers, mainly energy fluxes and shell-to-shell energy transfers. We perform dynamo simulations for the magnetic Prandtl number Pm = 20 on 10243 grid using the pseudospectral method. We demonstrate that the magnetic energy growth is caused by nonlocal energy transfers from the large-scale or forcing-scale velocity field to small-scale magnetic field. The peak of these energy transfers moves towards lower wave numbers as dynamo evolves, which is the reason why the integral scale of the magnetic field increases with time. The energy transfers U2U (velocity to velocity) and B2B (magnetic to magnetic) are forward and local. Copyright © EPLA, 2013.

Feasibility of Integrated Menu Recommendation and Self-Order System for Small-Scale Restaurants

Science.gov (United States)

Kashima, Tomoko; Matsumoto, Shimpei; Ishii, Hiroaki

2010-10-01

In recent years, point of sales (POS) systems with order function have been developed for restaurants. Since expensive apparatus and system are required for installing POS systems, usually only large-scale restaurant chains can afford to introduce them. In this research, we consider the POS management in a restaurant, which cooperates with an automatic order function by using a personal digital device aiming at the safety of the food, pursuit of service, and further operational efficiency improvements, such as foods management, accounting treatment, and ordering work. In traditional POS systems, information recommendation technology is not taken into consideration. We realize the recommendation of a menu according to the user's preference using rough sets and menu planning based on stock status by applying information recommendation technology. Therefore, we believe that this system can be used in comfort with regard to freshness of foods, allergy, diabetes, etc. Furthermore, due to the reduction of the personnel expenses by an operational efficiency improvement such technology becomes even feasible for small-scale stores.

Paternalistic Leadership in Korean Small and Medium Scale Enterprises: Applicability of a Turkish Paternalism Scale

Directory of Open Access Journals (Sweden)

Ulaş Çakar

2015-10-01

Full Text Available Social and cultural exchange between Korea and Turkey has been rapidly increasing and is expected to be accelerated for the future. Especially business exchange is interest of many people in both countries. This paper aims to provide insights for business people in Korea and Turkey to understand each country’s cultural aspects. Among different perspectives, paternalism is focused in the study. Paternalism is an important intersection of both cultures but it did not receive much attention. Even though both Turkish and Korean leaders are paternalistic, the origin of the characteristic is based on different background. The current studies of paternalism in Korea are based on Confucianism and economic crisis whereas those of Turkey are based on nomadic history, military Coup d'Etat, complicated bureaucracy, and economic instability. Using a paternalism scale developed with Turkish sample, this study measured Korean employees’ perception on paternalism and paternalistic leadership. The results showed that the scale is applicable in Korean organizations as well.

Hunter, Jennifer L; Krantz, Steven

2010-04-01

A graduate course on cultural diversity, based in constructivist theory and structured on the Process of Cultural Competence in the Delivery of Healthcare Services model, was developed and taught through classroom and online methods. The following research questions were explored: 1) Can an educational experience, built on constructivist learning theory tenets, change students' perceptions, attitudes, knowledge, and skills in the area of cultural competence? 2) Does the delivery method, online or traditional classroom, influence the degree of change? The study used a quasi-experimental, pretest-posttest control group design using the Inventory for Assessing the Process of Cultural Competence Among healthcare Professionals Revised. Findings showed significant changes (p<0.001) in cultural competence scores and subscores for all learners with both teaching modalities based on interval scale and in categories of cultural knowledge, skills, desire, and overall competence based on a nominal scale. The untaught construct of cultural desire showed the most significant improvement.

The current study investigated the role of cultural values in the resilience of Mexican American college students. Utilizing mixed methodology, 124 self-identified Mexican American college students were asked to complete an online survey, including a demographic questionnaire, the Resilience Scale, Mexican American Cultural Values Scale, and 2 open-ended questions concerning overcoming adversity and cultural values. As hypothesized, Mexican American traditional cultural values (Familismo, Respeto, Religiosidad, and Traditional Gender Roles) predicted resilience, with Familismo accounting for the majority of the variance. Consensual qualitative research (Hill, Thompson, & Nutt Williams, 1997) was used to identify emergent domains and themes within the open-ended question responses. Traditional Mexican American Value themes included Familismo, Ethnic Identity, Religiosidad, Perseverance, and Respeto. Results highlight the important role that certain Mexican American cultural values play in providing strength for overcoming adversities.

An Exercise in Theoretical Archaeology: Do Archaeological Cultures Exist?

Directory of Open Access Journals (Sweden)

Marko Porčić

2016-02-01

Full Text Available Archaeological culture still persists as a basic analytical and interpretative concept in Serbian archaeology despite criticism. This paper presents a formal view of archaeological cultures and explores the epistemological implications of this formalization. Formal analysis of archaeological culture is achieved through logical and quantitative explication of the traditional definition of archaeological cultures. The main result of the formal analysis is that there are real patterns of formal variability of material culture that may or may not correspond to traditional archaeological cultures. These patterns are real only in the analytical sense – they are real for given input data and scale of analysis. Unlike the traditional approach where this patterns are equated with archaeological cultures which are furthered interpreted in essentialist terms or as quasi- organic entities such as ethnic groups, it is claimed here that discovered patterns are only the starting point – the empirical situation that needs to be accounted for in anthropological an historical terms. This paper shows how patterns that are traditionally identified as archaeological cultures can arise as a consequence of an entire range of processes – different social and historical realities. The main conclusion is that the traditional concept of archaeological culture is not useful neither as analytical or interpretative tools for two reasons: 1 traditional cultures are subjectively defined entities with no theoretical justification for the criteria used in their definition and 2 the empirical pattern cannot be an explanation in itself because it is the thing that needs to be explained. Cultural evolutionary (transmission theory is proposed as a general framework for defining and interpreting patterns of formal variability of material culture in time and space.

Recapturing Traditional Culture - A Survey of Uvinmi Body Tattoo as a Curative Procedure in Esanland, Edo State, Nigeria

Full Text Available Body tattooing in traditional Nigerian culture was basically believed to be used for identification as well as aesthetic purposes. In some cultures, such as seen amongst the traditional ethnic Hausa and Fulani people, permanent facial marks were used to identify slaves within a community and also used to enhance the beauty and appearance of the women folk especially. In the southern part of Nigeria, amongst the Yorubas, it is used as a tribal identification symbol that provides information about the individual, as well as some culturally-related beliefs. The use of tattoos among the Esan ethnic people transcends the purposes of identification and enhancement of physical appearance as discovered. Thus this study examines the use of tattoo as a curative process for the illness called Udeh among the Esan ethnic people of Edo state Nigeria. Udeh is an illness associated with infection of the spleen. Data was collected through visitation of traditional healing venues, oral interview of some traditional doctors and elders as well as direct observation of the treatment processes. Findings indicated that the practice of Uvinmi has been in existence from time immemorial and it is a familial profession inherited from generation to generation as the most effective medium for treating spleen related diseases among the Esan people. It was also discovered contemporarily modern medical anaesthesia is employed to help reduce the agony felt in the process of blade incision as practiced by one of the traditional doctors. Recommendation made include an indebt study of the herbs used during and after treatment to gauge its efficacy on Western medicinal practices as well as proper sterilisization processes on incision equipments and procedures amongst others.

This study presents a biomedical device prototype based on small scale hydrodynamic cavitation. The application of small scale hydrodynamic cavitation and its integration to a biomedical device prototype is offered as an important alternative to other techniques, such as ultrasound therapy, and thus constitutes a local, cheap, and energy-efficient solution, for urinary stone therapy and abnormal tissue ablation (e.g., benign prostate hyperplasia (BPH)). The destructive nature of bubbly, cavitating, flows was exploited, and the potential of the prototype was assessed and characterized. Bubbles generated in a small flow restrictive element (micro-orifice) based on hydrodynamic cavitation were utilized for this purpose. The small bubbly, cavitating, flow generator (micro-orifice) was fitted to a small flexible probe, which was actuated with a micromanipulator using fine control. This probe also houses an imaging device for visualization so that the emerging cavitating flow could be locally targeted to the desired spot. In this study, the feasibility of this alternative treatment method and its integration to a device prototype were successfully accomplished.

Chapman, Derek S.; Reeves, Paige; Chapin, Michelle

2018-01-01

A comprehensive measure of organizational culture was developed using a lexical approach, a method typically employed within the study of personality. 1761 adjectives were narrowed down and factor analyzed, which resulted in the identification of a nine factor solution to organizational culture, including the dimensions of: Innovative, Dominant, Pace, Friendly, Prestigious, Trendy, Corporate Social Responsibility, Traditional, and Diverse. Comprised of 135 adjectives most frequently used in describing organizational culture by current employees of several hundred organizations, the Lexical Organizational Culture Scale (LOCS) was found to predict employee commitment, job satisfaction, job search behaviors, and subjective fit better than earlier scales of organizational culture.

Full Text Available The purpose of this paper is devoted to developing a chaotic artificial bee colony algorithm (CABC for the system identification of a small-scale unmanned helicopter state-space model in hover condition. In order to avoid the premature of traditional artificial bee colony algorithm (ABC, which is stuck in local optimum and can not reach the global optimum, a novel chaotic operator with the characteristics of ergodicity and irregularity was introduced to enhance its performance. With input-output data collected from actual flight experiments, the identification results showed the superiority of CABC over the ABC and the genetic algorithm (GA. Simulations are presented to demonstrate the effectiveness of our proposed algorithm and the accuracy of the identified helicopter model.

Multicultural adolescents between tradition and postmodernity: Dialogical Self Theory and the paradox of localization and globalization.

Science.gov (United States)

van Meijl, Toon

2012-01-01

This chapter builds on Dialogical Self Theory to investigate the identity development of adolescents growing up in multicultural societies. Their cultural identity is not only compounded by the rapid cultural changes associated with globalization, but also by the paradoxical revival of cultural traditions which the large-scale compression of time and space has incited at local levels of society. Dialogical Self Theory, which is based on the metaphor of the self as a "society of mind," helps to understand the dilemmas of tradition and postmodernity, of localization and globalization, within the self of individual youngsters.

Hogan, M E; Manners, G D

1990-03-01

Media and media extracts from callus cultures of small everlasting (Antennaria microphylla) inhibited leafy spurge (Euphorbia esula L.) callus tissue and suspension culture growth (50 and 70% of control, respectively) and were phytotoxic in lettuce and leafy spurge root elongation bioassays (64 and 77% of control, respectively). Hydroquinone, a phytotoxic compound previously isolated from small everlasting, was also biosynthesized by callus and suspension cultures of this species. Exogenously supplied hydroquinone (0.5 mM) was toxic to leafy spurge suspension culture cells and was only partially biotransformed to its nontoxic water-soluble monoglucoside, arbutin, by these cells. This report confirms the chronic involvement of hydroquinone in the allelopathic interaction between small everlasting and leafy spurge.

Dr. Thomas Balk

2010-07-30

Over the past decades, it has been well established that the mechanical behavior of materials changes when they are confined geometrically at least in one dimension to small scale. It is the aim of the 2010 Gordon Conference on 'Thin Film and Small Scale Mechanical Behavior' to discuss cutting-edge research on elastic, plastic and time-dependent deformation as well as degradation mechanisms like fracture, fatigue and wear at small scales. As in the past, the conference will benefit from contributions from fundamental studies of physical mechanisms linked to material science and engineering reaching towards application in modern applications ranging from optical and microelectronic devices and nano- or micro-electrical mechanical systems to devices for energy production and storage. The conference will feature entirely new testing methodologies and in situ measurements as well as recent progress in atomistic and micromechanical modeling. Particularly, emerging topics in the area of energy conversion and storage, such as material for batteries will be highlighted. The study of small-scale mechanical phenomena in systems related to energy production, conversion or storage offer an enticing opportunity to materials scientists, who can provide new insight and investigate these phenomena with methods that have not previously been exploited.

Małgorzata Bronikowska

2015-02-01

Full Text Available The aim of this article is to emphasize and acknowledge traditional sports as an important historical and socio-cultural phenomenon. By describing ‘the traditional sports and games movement’ from its organization to some key ideas, the authors show how local and national heritage of physical culture is important to every society. Within the current process of globalization, which touches on not only economic and political domains but also cultural and ethnic ones, people need to be aware of their heritage and identity. Various forms of our own, indigenous physical activity are part of this identity. In this article, the authors show the general background to the current situation of traditional sports in a globalized world, which is the socio-cultural context in which they exist, by describing some examples of these kinds of sports and initiatives all over the world. Afterwards, the focus will turn to a particular event – The 5thWorld Sport for All Games – during which traditional sports and games are played and promoted, showing the existence of this kind of sport as a potentially efficient tool in promoting cultural exchange and preserving heritage in the contemporary world.

2015-06-01

In cosmological scenarios with thermal inflation, extra eras of moduli matter domination, thermal inflation and flaton matter domination exist between primordial inflation and the radiation domination of Big Bang nucleosynthesis. During these eras, cosmological perturbations on small scales can enter and re-exit the horizon, modifying the power spectrum on those scales. The largest modified scale, k{sub b}, touches the horizon size when the expansion changes from deflation to inflation at the transition from moduli domination to thermal inflation. We analytically calculate the evolution of perturbations from moduli domination through thermal inflation and evaluate the curvature perturbation on the constant radiation density hypersurface at the end of thermal inflation to determine the late time curvature perturbation. Our resulting transfer function suppresses the power spectrum by a factor 0∼ 5 at k >> k{sub b}, with k{sub b} corresponding to anywhere from megaparsec to subparsec scales depending on the parameters of thermal inflation. Thus, thermal inflation might be constrained or detected by small scale observations such as CMB distortions or 21cm hydrogen line observations.

Homogeneity of small-scale earthquake faulting, stress, and fault strength

Science.gov (United States)

Hardebeck, J.L.

2006-01-01

Small-scale faulting at seismogenic depths in the crust appears to be more homogeneous than previously thought. I study three new high-quality focal-mechanism datasets of small (M angular difference between their focal mechanisms. Closely spaced earthquakes (interhypocentral distance small volumes of crust, while faults of many orientations may or may not be present, only similarly oriented fault planes produce earthquakes contemporaneously. On these short length scales, the crustal stress orientation and fault strength (coefficient of friction) are inferred to be homogeneous as well, to produce such similar earthquakes. Over larger length scales (???2-50 km), focal mechanisms become more diverse with increasing interhypocentral distance (differing on average by 40-70??). Mechanism variability on ???2- to 50 km length scales can be explained by ralatively small variations (???30%) in stress or fault strength. It is possible that most of this small apparent heterogeneity in stress of strength comes from measurement error in the focal mechanisms, as negligibble variation in stress or fault strength (<10%) is needed if each earthquake is assigned the optimally oriented focal mechanism within the 1-sigma confidence region. This local homogeneity in stress orientation and fault strength is encouraging, implying it may be possible to measure these parameters with enough precision to be useful in studying and modeling large earthquakes.

Full Text Available The article considers the influence of marketing on the TRANS­formation of a traditional society with its traditional values in a society of consumption. The de­velopment of capitalism inevitably leads to changes in the socio­political order of the whole modern world. This leads to the fact that the disappearance of the traditional elements of culture, crafts, songs and dances, rites, destroyed traditional norms and values, beliefs, moral and ethical values. Instead of the traditional culture is formed by the mass culture, society develops consumption goods and becoming all that you can sell. Marketing is one tool for the formation of a society of consumption, but it also performs other less prominent function transforms the traditional society into a consumer society with its values, mythology, norms and moral principles.

A review on technology maturity of small scale energy storage technologies★

Nguyen Thu-Trang

2017-01-01

Full Text Available This paper reviews the current status of energy storage technologies which have the higher potential to be applied in small scale energy systems. Small scale energy systems can be categorized as ones that are able to supply energy in various forms for a building, or a small area, or a limited community, or an enterprise; typically, they are end-user systems. Energy storage technologies are classified based on their form of energy stored. A two-step evaluation is proposed for selecting suitable storage technologies for small scale energy systems, including identifying possible technical options, and addressing techno-economic aspects. Firstly, a review on energy storage technologies at small scale level is carried out. Secondly, an assessment of technology readiness level (TRL is conducted. The TRLs are ranked according to information gathered from literature review. Levels of market maturity of the technologies are addressed by taking into account their market development stages through reviewing published materials. The TRLs and the levels of market maturity are then combined into a technology maturity curve. Additionally, market driving factors are identified by using different stages in product life cycle. The results indicate that lead-acid, micro pumped hydro storage, NaS battery, NiCd battery, flywheel, NaNiCl battery, Li-ion battery, and sensible thermal storage are the most mature technologies for small scale energy systems. In the near future, hydrogen fuel cells, thermal storages using phase change materials and thermochemical materials are expected to become more popular in the energy storage market.

2011-05-01

Continuous-flow centrifugation is widely utilized as the primary clarification step in the recovery of biopharmaceuticals from cell culture. However, it is a challenging operation to develop and characterize due to the lack of easy to use, small-scale, systems that can be used to model industrial processes. As a result, pilot-scale continuous centrifugation is typically employed to model large-scale systems requiring a significant amount of resources. In an effort to reduce resource requirements and create a system which is easy to construct and utilize, a capillary shear device, capable of producing energy dissipation rates equivalent to those present in the feed zones of industrial disk stack centrifuges, was developed and evaluated. When coupled to a bench-top, batch centrifuge, the capillary device reduced centrate turbidity prediction error from 37% to 4% compared to using a bench-top centrifuge alone. Laboratory-scale parameters that are analogous to those routinely varied during industrial-scale continuous centrifugation were identified and evaluated for their utility in emulating disk stack centrifuge performance. The resulting relationships enable bench-scale process modeling of continuous disk stack centrifuges using an easily constructed, scalable, capillary shear device coupled to a typical bench-top centrifuge.

Full Text Available Abstract Background The Peruvian Andean region is a main center of plant domestication of the world. There, several tuber species were domesticated and the area lodges one of the most important reservoirs of their varieties and wild relatives. It is also the setting of traditional cultures using and conserving them. However, crop genetic erosion has been reported in the region since several decades ago; therefore, understanding factors influencing both loss and maintenance of crop variation is relevant to design conservation policies. Previous researches have examined factors influencing agrobiodiversity conservation in the region but additional case studies are recognized to be still necessary for a deeper understanding of causes of genetic erosion and for policy design to prevent and remedy it. Our study focused on analyzing (1 variation in richness of traditional varieties of tubers cultivated among households, (2 changes in varieties richness occurred in four consecutive agricultural cycles, and (3 ecological, social, and cultural factors influencing loss and conservation of varieties. Methods Richness of farmer varieties of tuber species cultivated by 28 peasant households was monitored in communities of Cajamarca and Huánuco, Peru during four consecutive agricultural cycles (from 2001 to 2005. In-depth interviews were conducted with 12 of the households with higher reputation as conservationists, in order to document farmers' perception of tubers qualities in ecological, social, economic, technological and culinary aspects and how these influence their decisions of conservation priorities. Traditional varieties were identified according to their local names, which were then confronted among farmers and with scientific catalogues in order to identify synonyms.

Traditional food products (TFP) are an important part of European culture, identity, and heritage. In order to maintain and expand the market share of TFP, further improvement in safety, health, or convenience is needed by means of different innovations. The aim of this study was to obtain a consumer-driven definition for the concept of TFP and innovation and to compare these across six European countries (Belgium, France, Italy, Norway, Poland and Spain) by means of semantic and textual statistical analyses. Twelve focus groups were performed, two per country, under similar conditions. The transcriptions obtained were submitted to an ordinary semantic analysis and to a textual statistical analysis using the software ALCESTE. Four main dimensions were identified for the concept of TFP: habit-natural, origin-locality, processing-elaboration and sensory properties. Five dimensions emerged around the concept of innovation: novelty-change, variety, processing-technology, origin-ethnicity and convenience. TFP were similarly perceived in the countries analysed, while some differences were detected for the concept of innovation. Semantic and statistical analyses of the focus groups led to similar results for both concepts. In some cases and according to the consumers' point of view the application of innovations may damage the traditional character of TFP.

INTEGRATED DESIGN AND ENGINEERING USING BUILDING INFORMATION MODELLING: A PILOT PROJECT OF SMALL-SCALE HOUSING DEVELOPMENT IN THE NETHERLANDS

Directory of Open Access Journals (Sweden)

Rizal Sebastian

2010-11-01

Full Text Available During the design phase, decisions are made that affect, on average, 70% of the life-cycle cost of a building. Therefore, collaborative design relying on multidisciplinary knowledge of the building life cycle is essential. Building information modelling (BIM makes it possible to integrate knowledge from various project participants that traditionally work in different phases of the building process. BIM has been applied in a number of large-scale projects in the industrial real estate and infrastructure sectors in different countries, including The Netherlands. The projects in the housing sector, however, are predominantly small scale and carried out by small and medium enterprises (SMEs. These SMEs are looking for practical and affordable BIM solutions for housing projects. This article reports a pilot project of small-scale housing development using BIM in the province of Zeeland, The Netherlands. The conceptual knowledge derived from European and national research projects is disseminated to the SMEs through a series of experimental working sessions. Action learning protocols within a pilot project are developed to ensure direct impacts in terms of cost reduction and quality improvement. The project shows that BIM can be applied without radical changes to the SMEs' information and communication technology systems or to their business organizations.

Korea has the highest suicide rate amongst the OECD countries. Yet, its research on suicidal behaviors has been primitive. While the Interpersonal Psychological Theory of Suicide has gained global attention, there has only been a few researches, which examined its applicability in Korea. In this article, we review the previous studies on suicide and examine the association between the Interpersonal Psychological Theory of Suicide and traditional Korean culture, with an emphasis on Collectivism and Confucianism. We propose that pathways to suicide might vary depending on cultural influences. Clinical implications and suggestions for future research will be discussed.

Using numerical simulations of charged-particles propagating in the heliospheric magnetic field, we study small-scale gradients, or 'dropouts,' in the intensity of solar energetic particles seen at 1 AU. We use two turbulence models, the foot-point random motion model and the two-component model, to generate fluctuating magnetic fields similar to spacecraft observations at 1 AU. The turbulence models include a Kolmogorov-like magnetic field power spectrum containing a broad range of spatial scales from those that lead to large-scale field-line random walk to small scales leading to resonant pitch-angle scattering of energetic particles. We release energetic protons (20 keV-10 MeV) from a spatially compact and instantaneous source. The trajectories of energetic charged particles in turbulent magnetic fields are numerically integrated. Spacecraft observations are mimicked by collecting particles in small windows when they pass the windows at a distance of 1 AU. We show that small-scale gradients in the intensity of energetic particles and velocity dispersions observed by spacecraft can be reproduced using the foot-point random motion model. However, no dropouts are seen in simulations using the two-component magnetic turbulence model. We also show that particle scattering in the solar wind magnetic field needs to be infrequent for intensity dropouts to form.

Organizational Culture and Scale Development: Methodological Challenges and Future Directions

Full Text Available Defining and measuring organizational culture (OC is of paramount importance to organizations because a strong culture could potentially increase service quality and yield sustainable competitive advantages. However, such process could be challenging to managers because the scope of OC has been defined differently across disciplines and industries, which has led to the development of various scales for measuring OC. In addition, previously developed OC scales may also not be fully applicable in the hospitality and tourism context. Therefore, by highlighting the key factors affecting the business environment and the unique characteristics of hospitality industry, this paper aims to align the scope of OC closely with the industry and to put forth the need for a new OC scale that accurately responds to the context of the hospitality industry.

Small-scale classification schemes

Small-scale classification schemes are used extensively in the coordination of cooperative work. This study investigates the creation and use of a classification scheme for handling the system requirements during the redevelopment of a nation-wide information system. This requirements...... classification inherited a lot of its structure from the existing system and rendered requirements that transcended the framework laid out by the existing system almost invisible. As a result, the requirements classification became a defining element of the requirements-engineering process, though its main...... effects remained largely implicit. The requirements classification contributed to constraining the requirements-engineering process by supporting the software engineers in maintaining some level of control over the process.

Small-Scale Combined Heat and Power Plants Using Biofuels

Energy Technology Data Exchange (ETDEWEB)

Salomon-Popa, Marianne [Royal Inst. of Tech., Stockholm (Sweden). Dept. of Energy Technology

2002-11-01

In this time period where energy supply and climate change are of special concern, biomass-based fuels have attracted much interest due to their plentiful supply and favorable environmental characteristics (if properly managed). The effective capture and continued sustainability of this renewable resource requires a new generation of biomass power plants with high fuel energy conversion. At the same time, deregulation of the electricity market offers new opportunities for small-scale power plants in a decentralized scheme. These two important factors have opened up possibilities for small-scale combined heat and power (CHP) plants based on biofuels. The objective of this pre-study is to assess the possibilities and technical limitations for increased efficiency and energy utilization of biofuels in small size plants (approximately 10 MWe or lower). Various energy conversion technologies are considered and proven concepts for large-scale fossil fuel plants are an especially important area. An analysis has been made to identify the problems, technical limitations and different possibilities as recognized in the literature. Beyond published results, a qualitative survey was conducted to gain first-hand, current knowledge from experts in the field. At best, the survey results together with the results of personal interviews and a workshop on the role of small-scale plants in distributed generation will serve a guideline for future project directions and ideas. Conventional and novel technologies are included in the survey such as Stirling engines, combustion engines, gas turbines, steam turbines, steam motors, fuel cells and other novel technologies/cycles for biofuels. State-of-the-art heat and power plants will be identified to clarify of the advantages and disadvantages as well as possible obstacles for their implementation.

Examples of backreaction of small-scale inhomogeneities in cosmology

Science.gov (United States)

Green, Stephen R.; Wald, Robert M.

2013-06-01

In previous work, we introduced a new framework to treat large-scale backreaction effects due to small-scale inhomogeneities in general relativity. We considered one-parameter families of spacetimes for which such backreaction effects can occur, and we proved that, provided the weak energy condition on matter is satisfied, the leading effect of small-scale inhomogeneities on large-scale dynamics is to produce a traceless effective stress-energy tensor that itself satisfies the weak energy condition. In this work, we illustrate the nature of our framework by providing two explicit examples of one-parameter families with backreaction. The first, based on previous work of Berger, is a family of polarized vacuum Gowdy spacetimes on a torus, which satisfies all of the assumptions of our framework. As the parameter approaches its limiting value, the metric uniformly approaches a smooth background metric, but spacetime derivatives of the deviation of the metric from the background metric do not converge uniformly to zero. The limiting metric has nontrivial backreaction from the small-scale inhomogeneities, with an effective stress energy that is traceless and satisfies the weak energy condition, in accord with our theorems. Our second one-parameter family consists of metrics which have a uniform Friedmann-Lemaître-Robertson-Walker limit. This family satisfies all of our assumptions with the exception of the weak energy condition for matter. In this case, the limiting metric has an effective stress-energy tensor which is not traceless. We emphasize the importance of imposing energy conditions on matter in studies of backreaction.

Small-scale and homelike facilities for older people with dementia are rising in current dementia care. In these facilities, a small number of residents live together and form a household with staff. Normal, daily life and social participation are emphasized. It is expected that these facilities improve residents' quality of life. Moreover, it may have a positive influence on staff's job satisfaction and families involvement and satisfaction with care. However, effects of these small-scale and homelike facilities have hardly been investigated. Since the number of people with dementia increases, and institutional long-term care is more and more organized in small-scale and homelike facilities, more research into effects is necessary. This paper presents the design of a study investigating effects of small-scale living facilities in the Netherlands on residents, family caregivers and nursing staff. A longitudinal, quasi-experimental study is carried out, in which 2 dementia care settings are compared: small-scale living facilities and regular psychogeriatric wards in traditional nursing homes. Data is collected from residents, their family caregivers and nursing staff at baseline and after 6 and 12 months of follow-up. Approximately 2 weeks prior to baseline measurement, residents are screened on cognition and activities of daily living (ADL). Based on this screening profile, residents in psychogeriatric wards are matched to residents living in small-scale living facilities. The primary outcome measure for residents is quality of life. In addition, neuropsychiatric symptoms, depressive symptoms and social engagement are assessed. Involvement with care, perceived burden and satisfaction with care provision are primary outcome variables for family caregivers. The primary outcomes for nursing staff are job satisfaction and motivation. Furthermore, job characteristics social support, autonomy and workload are measured. A process evaluation is performed to investigate to

Airfoil optimization for noise emission problem on small scale turbines

Energy Technology Data Exchange (ETDEWEB)

Gocmen, Tuhfe; Ozerdem, Baris [Mechanical Engineering Department, Yzmir Institute of Technology (Turkey)

2011-07-01

Wind power is a preferred natural resource and has had benefits for the energy industry and for the environment all over the world. However, noise emission from wind turbines is becoming a major concern today. This study paid close attention to small scale wind turbines close to urban areas and proposes an optimum number of six airfoils to address noise emission concerns and performance criteria. The optimization process aimed to decrease the noise emission levels and enhance the aerodynamic performance of a small scale wind turbine. This study determined the sources and the operating conditions of broadband noise emissions. A new design is presented which enhances aerodynamic performance and at the same time reduces airfoil self noise. It used popular aerodynamic functions and codes based on aero-acoustic empirical models. Through numerical computations and analyses, it is possible to derive useful improvements that can be made to commercial airfoils for small scale wind turbines.

Research into positive aspects of the psyche is growing as psychologists learn more about the protective role of positive processes in the development and course of mental disorders, and about their substantial role in promoting mental health. With increasing globalization, there is strong interest in studies examining positive constructs across cultures. To obtain valid cross-cultural comparisons, measurement invariance for the scales assessing positive constructs has to be established. The current study aims to assess the cross-cultural measurement invariance of questionnaires for 6 positive constructs: Social Support (Fydrich, Sommer, Tydecks, & Brähler, 2009), Happiness (Subjective Happiness Scale; Lyubomirsky & Lepper, 1999), Life Satisfaction (Diener, Emmons, Larsen, & Griffin, 1985), Positive Mental Health Scale (Lukat, Margraf, Lutz, van der Veld, & Becker, 2016), Optimism (revised Life Orientation Test [LOT-R]; Scheier, Carver, & Bridges, 1994) and Resilience (Schumacher, Leppert, Gunzelmann, Strauss, & Brähler, 2004). Participants included German (n = 4,453), Russian (n = 3,806), and Chinese (n = 12,524) university students. Confirmatory factor analyses and measurement invariance testing demonstrated at least partial strong measurement invariance for all scales except the LOT-R and Subjective Happiness Scale. The latent mean comparisons of the constructs indicated differences between national groups. Potential methodological and cultural explanations for the intergroup differences are discussed.

2016-01-01

As the population in the United States grows more diverse, nurses caring for childbearing women must be aware of the many cultural traditions and customs unique to their patients. This knowledge and insight supports women and their families with the appropriate care, information, and resources. A supportive relationship builds trust, offers guidance, and allows for the new family to integrate information from nurses and other healthcare providers with the practice of certain perinatal cultural traditions. The Asian Indian culture is rich in tradition, specifically during the perinatal period. To support the cultural beliefs and practices of Asian Indian women during this time, nurses need to be aware of and consider multiple factors. Many women are navigating the new role of motherhood while making sense of and incorporating important cultural rituals. The purpose of this article is to provide an overview of perinatal cultural practices and traditions specific to the Asian Indian culture that perinatal nurses may observe in the clinical setting. Cultural traditions and practices specific to the pregnancy and postpartum period are described together with symbolism and implications for nursing practice. It is important to note that information regarding perinatal customs is provided in an effort to promote culturally sensitive nursing care and may not pertain to all Asian Indian women living in the United States.

Bollywood Dreams? The Rise of the Asian Mela as a Global Cultural Phenomenon

Directory of Open Access Journals (Sweden)

Melanie Smith

2006-03-01

Full Text Available This article will examine some of the complexities inherent in the development of Asian Mela festivals from small-scale community-based events in India, to national celebrations of Diasporic culture in Western countries. Like Caribbean Carnivals, Melas are becoming more popular as a global cultural tourism phenomenon and are increasingly being promoted to white and tourist audiences. This similarly engenders fears of cultural dilution, distortion, and ‘Othering’. The programming of Melas is apparently keeping pace with the exporting, re-packaging and hybridisation of other forms of Asian culture, such as cuisine, music, fashion, and cinema. But does this symbolise a Bollywood dream or just another post-colonial appropriation of indigenous or Disaporic cultures? Cultural protectionism is certainly a contentious issue within Diasporic communities, where inter-generational differences of opinion can lead to conflict and confusion. Identity construction is complex and worthy of further examination in the context of Melas, which traditionally served to celebrate ethnic community and folk cultures and identities, but are increasingly becoming a showcase for global and hybridised cultural forms. The article will examine these issues, as well as providing an analysis of the factors and mechanisms that are driving the development of Melas forward. This will include the role and vision of artistic directors of Melas, the contribution of ethnic communities to cultural continuity, and issues relating to audience and tourism development. A case study of the Edinburgh Mela will be presented, which exemplifies a number of the aforementioned issues, focusing in particular on national and Diasporic identity construction, and the tensions between popular and traditional cultural forms.

Ethnic roots of cultural tradition illustrated in Kaimur rock art

Full Text Available Ethno archaeological evidences and studies very often facilitate the interpretation of significance of rock art. But sometimes there are problems in explaining the things if there is discrepancy between local ethnic activities and the rock art of by-gone days which may be due to either a remarkable shift in social behaviors during long period span or to the relative seclusion of the developing society from art traditions manifested in local rock art. The present paper is based on the ethno rock art investigation made in the Kaimur region of Bihar. In this paper the author has attempted to link between ancient rock art living pattern and the art and culture of modern local group especially the tribe and semi tribes residing in the hill, foot hill and the plain.

Spontaneous cocoa bean fermentations performed under bench- and pilot-scale conditions were studied using an integrated microbiological approach with culture-dependent and culture-independent techniques, as well as analyses of target metabolites from both cocoa pulp and cotyledons. Both fermentation ecosystems reached equilibrium through a two-phase process, starting with the simultaneous growth of the yeasts (with Saccharomyces cerevisiae as the dominant species) and lactic acid bacteria (LAB) (Lactobacillus fermentum and Lactobacillus plantarum were the dominant species), which were gradually replaced by the acetic acid bacteria (AAB) (Acetobacter tropicalis was the dominant species). In both processes, a sequence of substrate consumption (sucrose, glucose, fructose, and citric acid) and metabolite production kinetics (ethanol, lactic acid, and acetic acid) similar to that of previous, larger-scale fermentation experiments was observed. The technological potential of yeast, LAB, and AAB isolates was evaluated using a polyphasic study that included the measurement of stress-tolerant growth and fermentation kinetic parameters in cocoa pulp media. Overall, strains L. fermentum UFLA CHBE8.12 (citric acid fermenting, lactic acid producing, and tolerant to heat, acid, lactic acid, and ethanol), S. cerevisiae UFLA CHYC7.04 (ethanol producing and tolerant to acid, heat, and ethanol), and Acetobacter tropicalis UFLA CHBE16.01 (ethanol and lactic acid oxidizing, acetic acid producing, and tolerant to acid, heat, acetic acid, and ethanol) were selected to form a cocktail starter culture that should lead to better-controlled and more-reliable cocoa bean fermentation processes.

Kertha Gosa Klungkung Court Hall in Bali is one of the relics of the cultural heritage of The Kingdom of Bali which is a part of the Klungkung Castle. The existence of Kertha Gosa Architecture Hall as one of the relics of cultural heritage holds historical values, especially Bali traditional values. Indonesia is a country which has the rich culture heritage history, especially on historical buildings. This research seeks for a redenomination to solve problems being faced recently, namely the lack of activities to conserve a historic building as an asset of the country and source of knowledge in education. Listed in Law Number 11 of 2010 the conservation has some criteria, such as : 1.it has 50 years or more; represents the period of a certain style lat least 50 years; has special meaning for the history, science, education, religion, and culture or cultural value as a nation’s personality. The procedure to conduct this research uses a descriptive method by doing observation, interviews, taking some pictures, official documents or personal and other data that have a relevance to the research related to object to describing the condition of the building systematically, factual and actual. Consideration of the selection of objects is based on research by looking at the criteria of architectural, historical and symbolic criteria. Kertha Gosa Hall classic has been there for 395 years was built with zoning system called Sanga Mandala or similar to a chess board using natural materials such as eben wood, and padas rocks which make it authentic and possesses characteristic values of patriotism expression. During the kingdom of Kertha Gosa, Court Hall was like a court nowadays, but people still trust the constructive value of Hindu religion and culture as a product of thinking and live experience.

2007-12-01

Using two new scales, this study examined beliefs in genetic determinism and attitudes towards psychiatric genetic research in student samples from Austria, Malaysia, Romania, and the United Kingdom. For both constructs, effects of culture were detectable, whereas those related to key demographics were either small and inconsistent across samples (political orientation and religiosity) or zero (sex and age). Judged from factorial dimensionality and internal consistency, the psychometric properties of both scales were satisfactory. Belief in genetic determinism had lower prevalence and corresponded only modestly to positive attitudes towards psychiatric genetic research which had higher prevalence. The correlations of both constructs with a preference of inequality among social groups (social dominance orientation) were modest and inconsistent across samples. Both scales appear appropriate for cross-cultural applications, in particular for research into lay theories and public perceptions regarding genetic vs environmental effects on human behavior, mental disorders, and behavioral and psychiatric genetic research related to these.

Small-scale tunnel test for blast performance

International Nuclear Information System (INIS)

Felts, J E; Lee, R J

2014-01-01

The data reported here provide a validation of a small-scale tunnel test as a tool to guide the optimization of new explosives for blast performance in tunnels. The small-scale arrangement consisted of a 2-g booster and 10-g sample mounted at the closed end of a 127 mm diameter by 4.6-m long steel tube with pressure transducers along its length. The three performance characteristics considered were peak pressure, initial energy release, and impulse. The relative performance from five explosives was compared to that from a 1.16-m diameter by 30-m long tunnel that used 2.27-kg samples. The peak pressure values didn't correlate between the tunnels. Partial impulse for the explosives did rank similarly. The initial energy release was determined from a one-dimensional point-source analysis, which nearly tracked with impulse suggesting additional energy released further down the tunnel for some explosives. This test is a viable tool for optimizing compositional variations for blast performance in target scenarios of similar geometry.

Over the last decade, sustainable energy consumption has attracted the attention of scientists and researchers. The current paper presents sustainability indicators of a small scale turbojet engine, operated on micro-aerial vehicles, for discussion of the sustainable development of the aviation industry from a different perspective. Experimental data was obtained from an engine at full power load and utilized to conduct an exergy-based sustainability analysis. Exergy efficiency, waste exergy ratio, recoverable exergy ratio, environmental effect factor, exergy destruction factor and exergetic sustainability index are evaluated as exergetic sustainability indicators of the turbojet engine under investigation in the current study. The exergy efficiency of the small scale turbojet engine is calculated as 27.25 % whereas the waste exergy ratio, the exergy destruction factor and the sustainability index of the engine are found to be 0.9756, 0.5466 and 0.2793, respectively.

To gauge the collateral impacts of fishing we must know where fishing boats operate and how much they fish. Although small-scale fisheries land approximately the same amount of fish for human consumption as industrial fleets globally, methods of estimating their fishing effort are comparatively poor. We present an accessible, spatial method of calculating the effort of small-scale fisheries based on two simple measures that are available, or at least easily estimated, in even the most data-poor fisheries: the number of boats and the local coastal human population. We illustrate the method using a small-scale fisheries case study from the Gulf of California, Mexico, and show that our measure of Predicted Fishing Effort (PFE), measured as the number of boats operating in a given area per day adjusted by the number of people in local coastal populations, can accurately predict fisheries landings in the Gulf. Comparing our values of PFE to commercial fishery landings throughout the Gulf also indicates that the current number of small-scale fishing boats in the Gulf is approximately double what is required to land theoretical maximum fish biomass. Our method is fishery-type independent and can be used to quantitatively evaluate the efficacy of growth in small-scale fisheries. This new method provides an important first step towards estimating the fishing effort of small-scale fleets globally.

Inquiry into the Indigenous, Cultural and Traditional Astronomical Knowledge: A case of the Lamba land of Zambia

Indigenous astronomy in the context of Zambia is the oral astronomy knowledge, culture and beliefs which relate to celestial bodies, astronomy events and related behaviour that are held by the elderly persons and passed on to younger generations. Much is not written down and with the passing away of the custodians, this knowledge is threatened to be extinct. A mini study of the astronomical beliefs and culture of the ancient Zambian community during the International Year of Astronomy (IYA) 2009 revealed that such knowledge existed. A comprehensive study assesses cultural and traditional knowledge on astronomy and to ascertain how much of this knowledge has been passed on to the younger generations. Open-ended interviews were conducted using questionnaires and focus group discussions. Respondents were identified by snowball sampling of the elderly people and random sampling of the middle aged and young. Nine randomly sampled districts of the Copperbelt Province were considered. The collected data has been analysed using MAXQDA software. Knowledge of traditional astronomy is high among the elderly people and declining with age hence the need for documenting and introducing it in the school curriculum and regular public discourse.

This study reports on the psychometric properties of the 11-item Perceived Wellness Culture and Environment Support Scale (PWCESS) and its relationship with employee healthy lifestyle beliefs and behaviors. Faculty and staff (N = 3959) at a large public university in the United States mid-west completed the PWCESS along with healthy lifestyle beliefs and behaviors scales. Data were randomly split into 2 halves to explore the PWCESS' validity and reliability and the second half to confirm findings. Principal components analysis indicated a unidimensional construct. The PWCESS was positively related to healthy lifestyle beliefs and behaviors supporting the scale's validity. Confirmatory factor analysis supported the unidimensional construct (Cronbach's α = .92). Strong evidence supports the validity and reliability of the PWCESS. Future use of this scale could guide workplace intervention strategies to improve organizational wellness culture and employee health outcomes.

French, English or Kanak Languages? Can Traditional Languages and Cultures Be Sustained in New Caledonia?

Preliminary results from the study show a difference in the language habits between older and younger generations on New Caledonians of Melanesian descent. Although French is perceived as the lingua franca by all, English is more valued than ancestral Melanesian languages by the younger generations. In terms of cultural representations and links with family history, there seems to be a discrepancy between the younger and the older generations. Whilst the older generations perceive the Centre Culturel Tjibaou as a traditional space for Melanesian art and culture their younger counterparts on the contrary view it as a place associated with contemporary art and music performances.

The EXOS-D fluxgate magnetometer data obtained at 3,000-10,000 km altitude have shown that small-scale field-aligned currents always exist in large-scale region 1, region 2, cusp and polar cap current systems. Assuming that these small-scale field-aligned currents have current sheet structure, the width of current sheet is estimated to be 5-20 km at ionospheric altitude. By comparing the magnetometer data with charged particle and high frequency plasma wave data simultaneously obtained from EXOS-D, it is found that small-scale currents have one-to-one correspondence with localized electron precipitation events characterized by flux enhancement over a wide energy range from 10 eV to several keV and broadband electrostatic bursts occasionally extending above local plasma frequencies or electron cyclotron frequencies

Palm fruit in traditional African food culture.

The centre of origin of the oil palm is the tropical rain forest region of West Africa. It is considered to be the 200-300 kilometre wide coastal belt between Liberia and Mayumbe. The oil palm tree has remained the 'tree of life' of Yoruba land as well as of other parts of southern West Africa to which it is indigenous. The Yoruba are adept at spinning philosophical and poetical proverbs around such ordinary things as hills, rivers, birds, animals and domestic tools. Hundreds of the traditional proverbs are still with us, and through them one can see the picture of the environment that contributed to the moulding of the thoughts of the people. Yoruba riddles or puzzles were also couched in terms of the environment and the solutions to them were also environmental items. They have a popular saying: A je eran je eran a kan egungun, a je egungun je egungun a tun kan eran: 'A piece of meat has an outer layer of flesh, an intermediate layer of bone and an inner layer of flesh'. What is it? A palm fruit: it has an outer edible layer, the mesocarp; then a layer of shell, inedible, and the kernel inside, edible. The solution to this puzzle summarises the botanical and cultural characteristics of the palm fruit.

Some scaling effects related to the experimental facilities as well as to the analytical models used for the design and safety analysis of nuclear power plants are discussed or the basis of phenomena expected to occur during small-break loss - of - coolant accidents. The results of isolated small-break experiments should not be directly extrapolated to the safety analysis of commercial reactors, due to the scaling distortions inherent to the test facilities. With respect to the analytical models used to simulate thermohydraulic processes in experimental facilities, their eventual dependence relative to the system dimension should be examined in order to assess their applicability to the safety analysis of commercial power plants.

to transport, and the loss of biogas as a result of cracks and the intentional release of excess biogas. In this study, life cycle assessment (LCA) methodology was used to assess the environmental impacts associated with biogas digesters in Vietnam. Handling 1,000 kg of liquid manure and 100 kg of solid manure......Small-scale household digesters have been promoted across Asia as a sustainable way of handling manure. The major advantages are that they produce biogas and reduce odor. However their disadvantages include the low recycling of nutrients, because digestate is dilute and therefore difficult...... in a system with a biogas digester reduced the impact potential from 4.4 kg carbon dioxide (CO 2) equivalents to 3.2 kg CO2 equivalents compared with traditional manure management. However, this advantage could easily be compromised if digester construction is considered in the LCA or in situations where...

Chronically nitrate-loaded riparian buffer zones show high N 2 O emissions. Often, a large part of the N 2 O is emitted from small surface areas, resulting in high spatial variability in these buffer zones. These small surface areas with high N 2 O emissions (hotspots) need to be investigated to generate knowledge on the factors governing N 2 O emissions. In this study the N 2 O emission variability was investigated at different spatial scales. Therefore N 2 O emissions from three 32 m 2 grids were determined in summer and winter. Spatial variation and total emission were determined on three different scales (0.3 m 2 , 0.018 m 2 and 0.0013 m 2 ) at plots with different levels of N 2 O emissions. Spatial variation was high at all scales determined and highest at the smallest scale. To test possible factors inducing small scale hotspots, soil samples were collected for slurry incubation to determine responses to increased electron donor/acceptor availability. Acetate addition did increase N 2 O production, but nitrate addition failed to increase total denitrification or net N 2 O production. N 2 O production was similar in all soil slurries, independent of their origin from high or low emission soils, indicating that environmental conditions (including physical factors like gas diffusion) rather than microbial community composition governed N 2 O emission rates

Recent advances in statistical parameterizations of cirrus cloud processes for use in global models are highlighting the need for information about small-scale fluctuations in upper tropospheric humidity and the physical processes that control the humidity variability. To address these issues, we have analyzed high-resolution airborne water vapor measurements obtained in the Airborne Tropical TRopopause EXperiment over the tropical Pacific between 14 and 20 km. Using accurate and precise 1-Hz water vapor measurements along approximately-level aircraft flight legs, we calculate structure functions spanning horizontal scales ranging from about 0.2 to 50 km, and we compare the water vapor variability in the lower (about 14 km) and upper (16-19 km) Tropical Tropopause Layer (TTL). We also compare the magnitudes and scales of variability inside TTL cirrus versus in clear-sky regions. The measurements show that in the upper TTL, water vapor concentration variance is stronger inside cirrus than in clear-sky regions. Using simulations of TTL cirrus formation, we show that small variability in clear-sky humidity is amplified by the strong sensitivity of ice nucleation rate to supersaturation, which results in highly-structured clouds that subsequently drive variability in the water vapor field. In the lower TTL, humidity variability is correlated with recent detrainment from deep convection. The structure functions indicate approximately power-law scaling with spectral slopes ranging from about -5/3 to -2.

Small Scale Problems of the ΛCDM Model: A Short Review

Directory of Open Access Journals (Sweden)

Antonino Del Popolo

2017-02-01

Full Text Available The ΛCDM model, or concordance cosmology, as it is often called, is a paradigm at its maturity. It is clearly able to describe the universe at large scale, even if some issues remain open, such as the cosmological constant problem, the small-scale problems in galaxy formation, or the unexplained anomalies in the CMB. ΛCDM clearly shows difficulty at small scales, which could be related to our scant understanding, from the nature of dark matter to that of gravity; or to the role of baryon physics, which is not well understood and implemented in simulation codes or in semi-analytic models. At this stage, it is of fundamental importance to understand whether the problems encountered by the ΛDCM model are a sign of its limits or a sign of our failures in getting the finer details right. In the present paper, we will review the small-scale problems of the ΛCDM model, and we will discuss the proposed solutions and to what extent they are able to give us a theory accurately describing the phenomena in the complete range of scale of the observed universe.

Notes on a Dramaturgical Analysis of Unequal Small-Scale Corruption Experiences

Directory of Open Access Journals (Sweden)

Edgar Daniel Manchinelly Mota

2017-10-01

Full Text Available In the last two decades, corruption has emerged as a relevant subject on a worldwide scale, because of its negative effects on the economy and State institutions, among other things. Research has focused on the macro aspects of corruption, emphasizing its causes and consequences. However, small-scale corruption has not been studied in such detail. This document proposes a theoretical-methodological framework for a dramaturgical analysis of small-scale corruption, with the aim of demonstrating that it is a stratified interaction. In this sense, corruption is an unequal experience for citizens, which depends on individuals’ social position.

Full Text Available OBJECTIVES: This study examines the association between cultural orientation and drinking behaviors among university students. Cultural orientation is the measure of how the cultural values of individuals living in their own society are influenced by cultural values introduced from the outside. METHODS: In 2011, a cross-sectional survey collected data from 1279 university students from six universities in central China. Participants used a likert scale to rank a series of statements reflecting cultural values from the previously validated Chinese Cultural Orientation Scale and answered questions about their drinking behaviors and socio-demographic characteristics. RESULTS: Statistically significant differences in cultural orientation were observed for gender, hometown and type of university attendance. Traditional-oriented students were more likely to be occasional drinkers or nondrinkers, while marginal-oriented students, bicultural-oriented students and western-oriented students were more likely to be regular drinkers. Bicultural orientation (OR = 1.80, P<0.05 and marginal orientation (OR = 1.64, P<0.05 increased the likelihood of the student being regular drinking, compared to students with traditional orientations. Males (OR = 4.40, P<0.05 had a higher likelihood of regular drinking than females, graduate students (OR = 2.59, P<0.05 had a higher likelihood of regular drinking than undergraduates, students from urban areas (OR = 1.79, P<0.05 had a higher likelihood of regular drinking than those from towns/rural areas, and students attending key universities (OR = 0.48, P<0.05 had a lower likelihood of regular drinking than those attending general universities. CONCLUSIONS: Cultural orientation influences drinking behaviors. Traditional cultural orientation was associated with less drinking while western cultural orientation, marginal cultural orientation and bicultural orientation were associated with more drinking.

Adopting small-scale production of electricity

Tengvard, Maria; Palm, Jenny (Linkoeping Univ., Dept. of Technology and Social Change, Linkoeping (Sweden)). e-mail: maria.tengvard@liu.se

2009-07-01

In Sweden in 2008, a 'new' concept for small-scale electricity production attracted massive media attention. This was mainly due to the efforts of Swedish company Egen El, which is marketing small-scale photovoltaics (PVs) and wind turbines to households, both homeowners and tenants. Their main selling point is simplicity: their products are so easy to install that everyone can do it. Autumn 2008 also saw IKEA announce that within three years it would market solar panels. How, then, do households perceive these products? Why would households choose to buy them? How do households think about producing their own electricity? Analysis of material based on in-depth interviews with members of 20 households reveals that environmental concerns supply the main motive for adopting PVs or micro wind power generation. In some cases, the adopting households have an extensively ecological lifestyle and such adoption represents a way to take action in the energy area. For some, this investment is symbolic: a way of displaying environmental consciousness or setting an example to others. For still others, the adoption is a protest against 'the system' with its large dominant actors or is a way to become self-sufficient. These microgeneration installations are rejected mainly on economic grounds; other motives are respect for neighbours and difficulties finding a place to install a wind turbine.

A Conceptual Framework for Agri-Food Tourism as an Eco-Innovation Strategy in Small Farms

Directory of Open Access Journals (Sweden)

Shang-Yu Liu

2017-09-01

Full Text Available The proposed conceptual framework explores how small-scale farms can combine agricultural products and tourism into an eco-innovation strategy. This paper presents a case study conducted on a family-run farm within the territory of the Paiwan tribal community of the North Dawu Mountain situated in the Central Mountain Range of Taiwan. The area has become an important coffee-farming region since the Japanese colonial period between 1895 and 1945. For many years, most of the indigenous farmers of the area have cultivated varieties of coffee plants using traditional, non-commercial methods, such as a single-sale channel. The small-scale farmer implements an integrated approach that systematically optimizes supply chain relationships to improve both the upstream and downstream sides of agri-food tourism services. The upstream element of agri-food tourism, for example, can be adjusted to employ organic or “natural” farming methods that allow small-scale farmers to secure an “organic” certification. Based on this approach, a small farm is gradually transformed into a type of educational institution that can demonstrate to customers the methods for farming high-quality organic coffee while also attracting tourists of various backgrounds to experience the downstream components of agri-food tourism in a recreational setting. This case study highlights how a particular small-scale farmer plays an important role in attracting other tribal farmers to engage in sustainable practices that help preserve cultural, social, and environmental systems while also presenting agri-food tourism as a brand identity.

Previous study concerned of qualitative modelling neutrally stratified flow over open-cut coal mine and important surrounding topography at meso-scale (1:9000) revealed an important area for quantitative modelling of atmospheric dispersion at small-scale (1:3300). The selected area includes a necessary part of the coal mine topography with respect to its future expansion and surrounding populated areas. At this small-scale simultaneous measurement of velocity components and concentrations in specified points of vertical and horizontal planes were performed by two-dimensional Laser Doppler Anemometry (LDA) and Fast-Response Flame Ionization Detector (FFID), respectively. The impact of the complex terrain on passive pollutant dispersion with respect to the prevailing wind direction was observed and the prediction of the air quality at populated areas is discussed. The measured data will be used for comparison with another model taking into account the future coal mine transformation. Thus, the impact of coal mine transformation on pollutant dispersion can be observed.

Because organizational culture is increasingly understood as fundamental to achieving high performance in hospital and other healthcare settings, the ability to measure this nuanced concept empirically has gained importance. Aside from measures of patient safety culture, no measure of organizational culture has been widely endorsed in the medical literature, limiting replication of previous findings and broader use in interventional studies. We sought to develop and assess the validity and reliability of a scale for assessing organizational culture in the context of hospitals' efforts to reducing 30-day risk-standardized mortality after acute myocardial infarction. The 31-item scale was completed by 147 individuals representing 10 hospitals during August and September 2014. The resulting organizational culture scale demonstrated high level of construct validity and internal consistency. Factor analyses indicated that the 31 items loaded well (loading values 0.48-0.90), supporting distinguishable domains of (1) learning environment, (2) psychological safety, (3) commitment to the organization, (4) senior management support, and (5) time for improvement efforts. Cronbach α coefficients were 0.94 for the scale and ranged from 0.77 to 0.88 for the subscales. The scale displayed reasonable convergent validity and statistically significant variability across hospitals, with hospital identity accounting for 11.3% of variance in culture scores across respondents. We developed and validated a relatively easy-to-administer survey that was able to detect substantial variability in organizational culture across different hospitals and may be useful in measuring hospital culture and evaluating changes in culture over time as part performance improvement efforts. © 2017 American Heart Association, Inc.

Scaling criteria and an assessment of Semiscale Mod-3 scaling for small-break loss-of-coolant transients

International Nuclear Information System (INIS)

Larson, T.K.; Anderson, J.L.; Shimeck, D.J.

1982-01-01

Various methods of scaling fluid thermal-hydraulic test facilities and their relative merits and disadvantages are examined in light of nuclear reactor safety considerations. Particular emphasis is placed on examination of the scaling of the Semiscale Mod-3 system and determination of thermal-hydraulic phenomena thought to be important during a small break loss-of-coolant accident in a pressurized water nuclear reactor. The influence of geometric and dynamic scaling concerns in the Mod-3 system on small break behavior are addressed from an engineering viewpoint and corrective measures contemplated or required to make results from Semiscale tests more meaningful relative to expected PWR response are discussed

Polymeric curved structures are widely used in imaging systems including optical fibers and microfluidic channels. Here, we demonstrate that small-scale, poly(dimethylsiloxane) (PDMS)-based, curved structures can be fabricated through controlling interfacial free energy equilibrium. Resultant structures have a smooth, symmetric, curved surface, and may be convex or concave in form based on surface tension balance. Their curvatures are controlled by surface characteristics (i.e., hydrophobicity and hydrophilicity) of the molds and semi-liquid PDMS. In addition, these structures are shown to be biocompatible for cell culture. Our system provides a simple, efficient and economical method for generating integrateable optical components without costly fabrication facilities.

Oster, Richard T; Grier, Angela; Lightning, Rick; Mayan, Maria J; Toth, Ellen L

2014-10-19

We used an exploratory sequential mixed methods approach to study the association between cultural continuity, self-determination, and diabetes prevalence in First Nations in Alberta, Canada. We conducted a qualitative description where we interviewed 10 Cree and Blackfoot leaders (members of Chief and Council) from across the province to understand cultural continuity, self-determination, and their relationship to health and diabetes, in the Alberta First Nations context. Based on the qualitative findings, we then conducted a cross-sectional analysis using provincial administrative data and publically available data for 31 First Nations communities to quantitatively examine any relationship between cultural continuity and diabetes prevalence. Cultural continuity, or "being who we are", is foundational to health in successful First Nations. Self-determination, or "being a self-sufficient Nation", stems from cultural continuity and is seriously compromised in today's Alberta Cree and Blackfoot Nations. Unfortunately, First Nations are in a continuous struggle with government policy. The intergenerational effects of colonization continue to impact the culture, which undermines the sense of self-determination, and contributes to diabetes and ill health. Crude diabetes prevalence varied dramatically among First Nations with values as low as 1.2% and as high as 18.3%. Those First Nations that appeared to have more cultural continuity (measured by traditional Indigenous language knowledge) had significantly lower diabetes prevalence after adjustment for socio-economic factors (p =0.007). First Nations that have been better able to preserve their culture may be relatively protected from diabetes.

In recent years, along with rapid development of targeted therapy in non-small cell lung cancer, traditional chemotherapy get less and less attention. Yet it still can not be ignored in the current that how to locate and use traditional chemotherapy so patients could derive maximum benefit. For this purpose, through the literature review and analysis, we point out there are still many traditional chemotherapy irreplaceable places whatever patients' driver gene status. And there are some new treatment modalities of traditional chemotherapy which have been developed to further improve patients' survival. At the same time, through exposition of predictive bio-markers development in chemotherapy, we pointed out that the future of traditional chemotherapy must be part of "targeted therapy".

A Mathematical Model of Profit-Loss Sharing Scheme of Small Investment for Traditional Market Traders using The Semi-Fuzzy Logic Approach

Directory of Open Access Journals (Sweden)

2017-02-01

Full Text Available A mathematical model of micro-finance investment using profit-loss sharing scheme are made and implemented to simulated data. Here profits from the venture will be shared in a portion between the investor and the entity running the business. The scheme can be classified as Musharaka type of investment in Sharia economy. The proposed model is theoretically implemented with data from small-scale traders at a local traditional market who have small turnover. They are common target of usurers who lend money with high interest rate and penalties. If the traders are in unfortunate conditions, they are potentially in poorer condition than before committing themselves to the usurer. In the conventional practices of the profit sharing scheme, the investor will get a fixed portion of the trader’s income, which is applied for all kind of small-scale traders. If the traders are diligent and hard worker and have very high turnover, then the investor will gain much more profit whether the contributed capital is small or large. In this paper, the scheme is implemented using Semi-Fuzzy Logic Approach so that the profit-loss sharing scheme can achieve its intended goal, which is to make a profitable investment not only for the investor but also for traders. The approach is not fully using Fuzzy Logic because some variables are still in crisp numbers and the optimization problem is regular in the form of crisp numbers. Based on the existing data, the results show that the optimal profit share is depended on the income of the traders. The higher the income coming from the venture, the lesser the profit share for the investor which is reasonable with the fixed initial contributed capital.

The Practical Application of Minor Element Control in Small Scale Melts

Science.gov (United States)

Jablonski, P. D.; Hawk, J. A.

Many times small scale melts are made for the purposes of alloy development, component evaluation, or simply economic concerns when "commercial" alloys are unavailable in small quantities. Not only is it critical that the major alloy elements meet the desired levels, but "tramp" elements or trace element additions must also be controlled. Control of tramp and trace elements on the small scale is often done differently simply due to the scale of the melt or the equipment available. In this paper several approaches will be presented that have been used at NETL in manufacturing alloys for in-house research, including, for example, vacuum refining. Also, the relative effectiveness of various gettering elements will be explored. The successes achieved as well as the failures of the various approaches will be discussed in terms of thermodynamic and kinetic considerations. The presentation will conclude with practical alloy examples.

Stigma plays in an important role in the lives of persons affected by neglected tropical diseases, and assessment of stigma is important to document this. The aim of this study is to test the cross-cultural validity of the Community Stigma Scale (EMIC-CSS) and the Social Distance Scale (SDS) in the field of leprosy in Cirebon District, Indonesia. Cultural equivalence was tested by assessing the conceptual, item, semantic, operational and measurement equivalence of these instruments. A qualitative exploratory study was conducted to increase our understanding of the concept of stigma in Cirebon District. A process of translation, discussions, trainings and a pilot study followed. A sample of 259 community members was selected through convenience sampling and 67 repeated measures were obtained to assess the psychometric measurement properties. The aspects and items in the SDS and EMIC-CSS seem equally relevant and important in the target culture. The response scales were adapted to ensure that meaning is transferred accurately and no changes to the scale format (e.g. lay out, statements or questions) of both scales were made. A positive correlation was found between the EMIC-CSS and the SDS total scores (r=0.41). Cronbach's alphas of 0.83 and 0.87 were found for the EMIC-CSS and SDS. The exploratory factor analysis indicated for both scales an adequate fit as unidimensional scale. A standard error of measurement of 2.38 was found in the EMIC-CSS and of 1.78 in the SDS. The test-retest reliability coefficient was respectively, 0.84 and 0.75. No floor or ceiling effects were found. According to current international standards, our findings indicate that the EMIC-CSS and the SDS have adequate cultural validity to assess social stigma in leprosy in the Bahasa Indonesia-speaking population of Cirebon District. We believe the scales can be further improved, for instance, by adding, changing and rephrasing certain items. Finally, we provide suggestions for use with other

Broad-scale small-world network topology induces optimal synchronization of flexible oscillators

International Nuclear Information System (INIS)

Markovič, Rene; Gosak, Marko; Marhl, Marko

2014-01-01

The discovery of small-world and scale-free properties of many man-made and natural complex networks has attracted increasing attention. Of particular interest is how the structural properties of a network facilitate and constrain its dynamical behavior. In this paper we study the synchronization of weakly coupled limit-cycle oscillators in dependence on the network topology as well as the dynamical features of individual oscillators. We show that flexible oscillators, characterized by near zero values of divergence, express maximal correlation in broad-scale small-world networks, whereas the non-flexible (rigid) oscillators are best correlated in more heterogeneous scale-free networks. We found that the synchronization behavior is governed by the interplay between the networks global efficiency and the mutual frequency adaptation. The latter differs for flexible and rigid oscillators. The results are discussed in terms of evolutionary advantages of broad-scale small-world networks in biological systems

Camellia reticulata is an arbor tree that has been cultivated in southwestern China by various sociolinguistic groups for esthetic purposes as well as to derive an edible seed oil. This study examined the influence of management, socio-economic factors, and religion on the genetic diversity patterns of Camellia reticulata utilizing a combination of ethnobotanical and molecular genetic approaches. Semi-structured interviews and key informant interviews were carried out with local communities in China's Yunnan Province. We collected plant material ( n  = 190 individuals) from five populations at study sites using single-dose AFLP markers in order to access the genetic diversity within and between populations. A total of 387 DNA fragments were produced by four AFLP primer sets. All DNA fragments were found to be polymorphic (100%). A relatively high level of genetic diversity was revealed in C. reticulata samples at both the species ( H sp  = 0.3397, I sp  = 0.5236) and population (percentage of polymorphic loci = 85.63%, H pop  = 0.2937, I pop  = 0.4421) levels. Findings further revealed a relatively high degree of genetic diversity within C. reticulata populations (Analysis of Molecular Variance = 96.31%). The higher genetic diversity within populations than among populations of C. reticulata from different geographies is likely due to the cultural and social influences associated with its long cultivation history for esthetic and culinary purposes by diverse sociolinguistic groups. This study highlights the influence of human management, socio-economic factors, and other cultural variables on the genetic and morphological diversity of C. reticulata at a regional level. Findings emphasize the important role of traditional culture on the conservation and utilization of plant genetic diversity.

Recent years have seen a dramatic rise in fermentation broth cell densities and a shift to extracellular product expression in microbial cells. As a result, dewatering characteristics during cell separation is of importance, as any liquor trapped in the sediment results in loss of product, and thus a decrease in product recovery. In this study, an ultra scale-down (USD) approach was developed to enable the rapid assessment of dewatering performance of pilot-scale centrifuges with intermittent solids discharge. The results were then verified at scale for two types of pilot-scale centrifuges: a tubular bowl equipment and a disk-stack centrifuge. Initial experiments showed that employing a laboratory-scale centrifugal mimic based on using a comparable feed concentration to that of the pilot-scale centrifuge, does not successfully predict the dewatering performance at scale (P-value centrifuge. Initial experiments used Baker's yeast feed suspensions followed by fresh Pichia pastoris fermentation cultures. This work presents a simple and novel USD approach to predict dewatering levels in two types of pilot-scale centrifuges using small quantities of feedstock (centrifuge needs to be operated, reducing the need for repeated pilot-scale runs during early stages of process development.

Highlights: • We analyzed minimum-cost options for small-scale DHSs under different contexts. • District heat production cost increases with reduced DHS scales. • Fewer technical options are suitable for small-scale DHSs. • Systems with combined technologies are less sensitive to changes in fuel prices. - Abstract: Efficient district heat production systems (DHSs) can contribute to achieving environmental targets and energy security for countries that have demands for space and water heating. The optimal options for a DHS vary with the environmental and social-political contexts and the scale of district heat production, which further depends on the size of the community served and the local climatic conditions. In this study, we design a small-scale, minimum-cost DHS that produces approximately 100 GWh heat per year and estimate the yearly production cost and primary energy use of this system. We consider conventional technologies, such as heat-only boilers, electric heat pumps and combined heat and power (CHP) units, as well as emerging technologies, such as biomass-based organic Rankine cycle (BORC) and solar water heating (SWH). We explore how different environmental and social-political situations influence the design of a minimum-cost DHS and consider both proven and potential technologies for small-scale applications. Our calculations are based on the real heat load duration curve for a town in southern Sweden. We find that the district heat production cost increases and that the potential for cogeneration decreases with smaller district heat production systems. Although the selection of technologies for a minimum-cost DHS depends on environmental and social-political contexts, fewer technical options are suitable for small-scale systems. Emerging technologies such as CHP-BORC and SWH improve the efficiency of primary energy use for heat production, but these technologies are more costly than conventional heat-only boilers. However, systems with

To describe the development of and test the validity and reliability of the Workplace Culture of Health (COH) scale. Exploratory factor analysis and confirmatory factor analysis were performed on data from a health care organization (N = 627). To verify the factor structure, confirmatory factor analysis was performed on a second data set from a medical equipment manufacturer (N = 226). The COH scale included a structure of five orthogonal factors: senior leadership and polices, programs and rewards, quality assurance, supervisor support, and coworker support. With regard to construct validity (convergent and discriminant) and reliability, two different US companies showed the same factorial structure, satisfactory fit statistics, and suitable internal and external consistency. The COH scale represents a reliable and valid scale to assess the workplace environment and culture for supporting health.

Advanced astigmatism-corrected tandem Wadsworth mounting for small-scale spectral broadband imaging spectrometer.

Lei, Yu; Lin, Guan-yu

2013-01-01

Tandem gratings of double-dispersion mount make it possible to design an imaging spectrometer for the weak light observation with high spatial resolution, high spectral resolution, and high optical transmission efficiency. The traditional tandem Wadsworth mounting is originally designed to match the coaxial telescope and large-scale imaging spectrometer. When it is used to connect the off-axis telescope such as off-axis parabolic mirror, it presents lower imaging quality than to connect the coaxial telescope. It may also introduce interference among the detector and the optical elements as it is applied to the short focal length and small-scale spectrometer in a close volume by satellite. An advanced tandem Wadsworth mounting has been investigated to deal with the situation. The Wadsworth astigmatism-corrected mounting condition for which is expressed as the distance between the second concave grating and the imaging plane is calculated. Then the optimum arrangement for the first plane grating and the second concave grating, which make the anterior Wadsworth condition fulfilling each wavelength, is analyzed by the geometric and first order differential calculation. These two arrangements comprise the advanced Wadsworth mounting condition. The spectral resolution has also been calculated by these conditions. An example designed by the optimum theory proves that the advanced tandem Wadsworth mounting performs excellently in spectral broadband.

Traditionally, the efforts of small scale fisheries have not been easily incorporated into the global picture of fishing effort and activity. That means that the activities of the vast majority ( 90%) of fishing vessels in the world have remained unquantified and largely opaque. With newly developed technology that harnesses solar power and cost-effective cellular networks to transmit data, it is becoming possible to provide vessel tracking systems on a large scale for vessels of all sizes. Furthermore, capitalizing on the relatively inexpensive cellular networks to transfer the data enables data of much higher granularity to be captured. By recording a vessel's position every few seconds, instead of minutes to hours as is typical of most satellite-based systems, we are able to resolve a diverse array of behaviors happening at sea including when and where fishing occurred and what type of fishing gear was used. This high granularity data is both incredibly useful and also a challenge to manage and mine. New approaches for handling and processing this continuous data stream of vessel positions are being developed to extract the most informative and actionable pieces of information for a variety of audiences including governing agencies, industry supply chains seeking transparency, non-profit organizations supporting conservation efforts, academic researchers and the fishers and boat owners.

Cross-cultural adaptation of the Maltreatment and Abuse Chronology of Exposure (MACE scale to Brazilian Portuguese

2016-03-01

Full Text Available Introduction : There is strong evidence to indicate that childhood maltreatment can negatively affect both physical and mental health and there is increasing interest in understanding the occurrence and consequences of such experiences. While several tools have been developed to retrospectively investigate childhood maltreatment experiences, most of them do not investigate the experience of witnessing family violence during childhood or bullying exposure. Moreover, the majority of scales do not identify when these experiences may have occurred, who was involved or the feelings evoked, such as helplessness or terror. The Maltreatment and Abuse Chronology of Exposure (MACE scale was developed to overcome these limitations. Objective : In view of the improvements over previous self-report instruments that this new tool offers and of the small number of self-report questionnaires for childhood maltreatment assessment available in Brazil, this study was conducted to conduct cross-cultural adaptation of the MACE scale for Brazilian Portuguese. Method : The following steps were performed: translation, back-translation, committee review for semantic and conceptual evaluation, and acceptability trial for equivalence. Results : Semantic and structural changes were made to the interview to adapt it for the Brazilian culture and all 75 of the items that comprise the longer version of MACE were translated. The results of the acceptability trial suggest that the items are comprehensible. Conclusion : The MACE scales may be useful tools for investigation of childhood maltreatment and make a valuable contribution to research in Brazil. Future studies should consider testing the availability and reliability of the three versions of the instrument translated into Brazilian Portuguese.

The Role of Small-Scale Biofuel Production in Brazil: Lessons for Developing Countries

Full Text Available Small-scale biofuel initiatives to produce sugarcane ethanol are claimed to be a sustainable opportunity for ethanol supply, particularly for regions with price-restricted or no access to modern biofuels, such as communities located far from the large ethanol production centers in Brazil and family-farm communities in Sub-Saharan Africa, respectively. However, smallholders often struggle to achieve economic sustainability with ethanol microdistilleries. The aim of this paper is to provide an assessment of the challenges faced by small-scale bioenergy initiatives and discuss the conditions that would potentially make these initiatives economically feasible. Ethanol microdistilleries were assessed through a critical discussion of existent models and through an economic analysis of different sugarcane ethanol production models. The technical-economic analysis showed that the lack of competitiveness against large-scale ethanol distillery, largely due to both low crop productivity and process efficiency, makes it unlikely that small-scale distilleries can compete in the national/international ethanol market without governmental policies and subsidies. Nevertheless, small-scale projects intended for local supply and integrated food–fuel systems seem to be an interesting alternative that can potentially make ethanol production in small farms viable as well as increase food security and project sustainability particularly for local communities in developing countries.

Ongoing shortages of care workers, together with an ageing population, make it of utmost importance to increase the quality of working life in nursing homes. Since the 1970s, normalised and small-scale nursing homes have been increasingly introduced to provide care in a family and homelike environment, potentially providing a richer work life for care workers as well as improved living conditions for residents. 'Normalised' refers to the opportunities given to residents to live in a manner as close as possible to the everyday life of persons not needing care. The study purpose is to provide a synthesis and overview of empirical research comparing the quality of working life - together with related work and health outcomes - of professional care workers in normalised small-scale nursing homes as compared to conventional large-scale ones. A systematic review of qualitative and quantitative studies. A systematic literature search (April 2015) was performed using the electronic databases Pubmed, Embase, PsycInfo, CINAHL and Web of Science. References and citations were tracked to identify additional, relevant studies. We identified 825 studies in the selected databases. After checking the inclusion and exclusion criteria, nine studies were selected for review. Two additional studies were selected after reference and citation tracking. Three studies were excluded after requesting more information on the research setting. The findings from the individual studies suggest that levels of job control and job demands (all but "time pressure") are higher in normalised small-scale homes than in conventional large-scale nursing homes. Additionally, some studies suggested that social support and work motivation are higher, while risks of burnout and mental strain are lower, in normalised small-scale nursing homes. Other studies found no differences or even opposing findings. The studies reviewed showed that these inconclusive findings can be attributed to care workers in some

Sustainable and Traditional Product Innovation without Scale and Experience, but Only for KIBS!

Full Text Available This study analyzes the ideal strategic trajectory for sustainable and traditional product innovation. Using a sample of 74 Costa Rican high-performance businesses for 2016, we employ fuzzy set analysis (qualitative comparative analysis to evaluate how the development of sustainable and traditional product innovation strategies is conditioned by the business’ learning capabilities and entrepreneurial orientation in knowledge-intensive (KIBS and non-knowledge-intensive businesses. The results indicate two ideal strategic configurations of product innovation. The first strategic configuration to reach maximum product innovation requires the presence of KIBS firms that have both an entrepreneurial and learning orientation, while the second configuration is specific to non-KIBS firms with greater firm size and age along with entrepreneurial and learning orientation. KIBS firms are found to leverage the knowledge-based and customer orientations that characterize their business model in order to compensate for the shortage of important organizational characteristics—which we link to liabilities or smallness and newness—required to achieve optimal sustainable and traditional product innovation.

Genetic programming based models in plant tissue culture: An addendum to traditional statistical approach.

Mridula, Meenu R; Nair, Ashalatha S; Kumar, K Satheesh

2018-02-01

In this paper, we compared the efficacy of observation based modeling approach using a genetic algorithm with the regular statistical analysis as an alternative methodology in plant research. Preliminary experimental data on in vitro rooting was taken for this study with an aim to understand the effect of charcoal and naphthalene acetic acid (NAA) on successful rooting and also to optimize the two variables for maximum result. Observation-based modelling, as well as traditional approach, could identify NAA as a critical factor in rooting of the plantlets under the experimental conditions employed. Symbolic regression analysis using the software deployed here optimised the treatments studied and was successful in identifying the complex non-linear interaction among the variables, with minimalistic preliminary data. The presence of charcoal in the culture medium has a significant impact on root generation by reducing basal callus mass formation. Such an approach is advantageous for establishing in vitro culture protocols as these models will have significant potential for saving time and expenditure in plant tissue culture laboratories, and it further reduces the need for specialised background.

Common scale features of the recent Greek and Serbian church chant traditions

Directory of Open Access Journals (Sweden)

Peno Vesna

2008-01-01

Full Text Available This paper is an attempt to show the similarity between the Serbian and Greek Post-Byzantine chanting traditions, especially those which relate to the scale organization of modes. Three teachers and reformers from Constantinople, Chrisantos, Gregorios and Chourmousios, established a fairly firm theoretical system for the first time during the long history of church chant. One of the main results of their reform, beside changes relating to neums, was the assignment of strict sizes to the intervals in the natural tonal system. There are three kinds of natural scales: diatonic, chromatic and encharmonic. They all have their place in the Greek Anastasimatarion chant book, whose first edition was prepared by Petar Peloponesios, and later edited by Ionnes Protopsaltes. The first, first plagal and forth plagal modes are diatonic in each of their melos, with very few exceptions; the second and second plagal are soft and hard chromatic, while the third and varis are encharmonic. It is important to note that the Greek chanter is very conscious of the scale foundation of the melody, so he begins to chant the apechima foremost, the intonation formula that comprehends all indisposed details to enter the adequate mode, i. e. melos. One mode could use one sort of scale for all groups of melodies - melos. However, in some modes there are different melos, whose scale organisation is not equal at all. That means that it is not proper to equate mode with scale, but rather to look for the specific scale's shape through the melodies that belong to the melos. The absence of formal Serbian church music theory and, especially, the very conservative way in which church melodies are learnt by ear and by heart, has caused significant gaps, which preclude an adequate approach to the essentional principals of Serbian chant. Over the years many Serbian chanters and musicians have noted down church melodies, especially those from the Octoechos, in F or in G, with the key

In developing countries the problem of air pollution was recognized earlier, however, it has acquired a greater dimension due to the conventional use of low grade fuels like coal, baggase, rice husk, etc. having high sulphur and ash content. The industrial sources contribute about 30--40% of the total emissions. In India, the small scale industries (low investment group) contribute about 60--80% of the total industrial emissions. These industries are characterized with various environmental pollution problems due to cluster of small scale industries located in sensitive area; use of low grade fuel, primitive processing techniques without emission abatement facilities etc., thus leading to enormous pollution in an confined region. Acute need was felt to reduce the pollution problem associated with small scale industries by use of cleaner fuel so as to reduce the localized problem. The paper presents the emissions associated with use of coal/coke, natural gas, LPG, and propane along with the fuel cost for small scale industrial sector of Agra, Firozabad and Mathura region. The studies carried out would find applicability to meet the air pollution standards based on shift in fuel and associated cost

Given the importance of ethnic differences in the evaluation of various aspects of symptoms in patients with Parkinson's disease (PD), we present the formal procedure for completing the traditional Chinese translation of the International and Parkinson and Movement Disorder Society/UPDRS (MDS-UPDRS) and highlight the discrepancy in nonmotor symptoms (NMS) between patients in Eastern and Western countries. A total of 350 native Chinese-speaking PD patients were recruited from multiple hospitals in Eastern countries; they completed the MDS-UPDRS. The translation process was executed and factor analysis was performed to determine the structure of the scale. Chi-squared and t tests were used to compare frequency and severity of PD symptoms between the Chinese-speaking and English-speaking groups (n = 876). NMS and motor symptoms were more severe in the Western population (Part I: t (1205) = 5.36, P < 0.0001; and Part III: t (1205) = 7.64, P < 0.0001); however, the prevalence of cognitive dysfunction and impairments in activities of daily living were more frequent in the Eastern patients. The comparative fit index was 0.93 or greater, and the exploratory factor analysis revealed compatible results between the translated scale and the original version. The traditional Chinese version of the MDS-UPDRS can be designated as an official translation of the original scale, and it is now available for use. Moreover, NMS in PD constitute a major issue worldwide, and the pattern of NMS among the Chinese population is more marked in terms of cognition-based symptoms and activities of daily living.

Traditional medicine has been practised in Ghana for centuries with the majority of Ghanaians still patronising the services of traditional healers. Throughout Africa a large number of people use pangolins as a source of traditional medicine, however, there is a dearth of information on the use of animals in folk medicine in Ghana, in particular the use of pangolins. The aim of this study was to determine the prevalent use of pangolins and the level of knowledge of pangolin use among traditional healers in Ghana for the treatment of human ailments. Data was gathered from 48 traditional healers using semi-structured interviews on the traditional medicinal use of pangolin body parts in the Kumasi metropolis of Ghana. The cultural importance index, relative frequency of citation, informant agreement ratio and use agreement values were calculated to ascertain the most culturally important pangolin body part as well as the level of knowledge dissemination among traditional healers with regards pangolin body parts. Our study revealed that 13 body parts of pangolins are used to treat various medicinal ailments. Pangolin scales and bones were the most prevalent prescribed body parts and indicated the highest cultural significance among traditional healing practices primarily for the treatment of spiritual protection, rheumatism, financial rituals and convulsions. Despite being classified under Schedule 1 of Ghana's Wildlife Conservation Act of 1971 (LI 685), that prohibits anyone from hunting or being in possession of a pangolin, our results indicated that the use of pangolins for traditional medicinal purposes is widespread among traditional healers in Ghana. A study on the population status and ecology of the three species of African pangolins occurring in Ghana is urgently required in order to determine the impact this harvest for traditional medical purposes has on their respective populations as current levels appear to be unmonitored and unsustainable.

Constraints on small-scale cosmological fluctuations from SNe lensing dispersion

2015-04-01

We provide predictions on small-scale cosmological density power spectrum from supernova lensing dispersion. Parameterizing the primordial power spectrum with running α and running of running β of the spectral index, we exclude large positive α and β parameters which induce too large lensing dispersions over current observational upper bound. We ran cosmological N-body simulations of collisionless dark matter particles to investigate non-linear evolution of the primordial power spectrum with positive running parameters. The initial small-scale enhancement of the power spectrum is largely erased when entering into the non-linear regime. For example, even if the linear power spectrum at k>10 hMpc -1 is enhanced by 1-2 orders of magnitude, the enhancement much decreases to a factor of 2-3 at late time (z≤1.5). Therefore, the lensing dispersion induced by the dark matter fluctuations weakly constrains the running parameters. When including baryon-cooling effects (which strongly enhance the small-scale clustering), the constraint is comparable or tighter than the PLANCK constraint, depending on the UV cut-off. Further investigations of the non-linear matter spectrum with baryonic processes is needed to reach a firm constraint.

Concerns arising due to the variability and intermittency of renewable energy sources while integrating with the power grid can be mitigated to an extent by incorporating a storage element within the renewable energy harnessing system. Thus, battery energy storage systems (BESS) are likely to have a significant impact in the small-scale integration of renewable energy sources into commercial building and residential dwelling. These storage technologies not only enable improvements in consumption levels from renewable energy sources but also provide a range of technical and monetary benefits. This paper provides a modelling framework to be able to quantify the associated benefits of renewable resource integration followed by an overview of various small-scale energy storage technologies. A simple, practical and comprehensive assessment of battery energy storage technologies for small-scale renewable applications based on their technical merit and economic feasibility is presented. Software such as Simulink and HOMER provides the platforms for technical and economic assessments of the battery technologies respectively. (author)

Impact of small-scale geometric roughness on wetting behavior.

Science.gov (United States)

Kumar, Vaibhaw; Errington, Jeffrey R

2013-09-24

We examine the extent to which small-scale geometric substrate roughness influences the wetting behavior of fluids at solid surfaces. Molecular simulation is used to construct roughness wetting diagrams wherein the progression of the contact angle is traced from the Cassie to Wenzel to impregnation regime with increasing substrate strength for a collection of systems with rectangularly shaped grooves. We focus on the evolution of these diagrams as the length scale of the substrate features approaches the size of a fluid molecule. When considering a series of wetting diagrams for substrates with fixed shape and variable feature periodicity, we find that the diagrams progressively shift away from a common curve as the substrate features become smaller than approximately 10 fluid diameters. It is at this length scale that the macroscopic models of Cassie and Wenzel become unreliable. Deviations from the macroscopic models are attributed to the manner in which the effective substrate-fluid interaction strength evolves with periodicity and the important role that confinement effects play for substrates with small periodicities.

The main project goal is delivering ICT tools (map and crowdfunding platforms and procedures as well as improving the capacity of stakeholders to sustainably valorize hidden resources. The underlying approach has capitalized on existing technologies and experiences through the development of an advanced interactive multimedia map using data produced in the Ljubljana Process. Subsequently, the map will be extended by collecting more data on the Lake Ohrid Region, which has been selected as a pilot area to promote the neglected inland, relieving pressure on more famous coastal sites. A contest among schools will enrich the database, uploading multifaceted memories collected by students. The winning cultural asset will be the object of a small-scale rehabilitation project supported by a fundraising campaign through a crowdfunding platform. The centrality of people’s active participation will contribute to governance innovation by reverting to traditional top-down promotion processes and practices, in which heritage consumers represent passive recipients of ready-made offers and messages. The map platform also holds specific potential for cultural tourism purposes, avoiding mistakes in the geo-localization of sites.

Overcurrent protection of transformers. Part 2: Traditional and new fusing philosophies for small and large transformers

Energy Technology Data Exchange (ETDEWEB)

Cook, C. J.; Niemira, J. K.

2003-07-01

New and traditional fusing philosophies for protecting transformers are discussed. This second in a two-part paper covers selection criteria for a transformer-primary fuse to protect the transformer consistent with industry-accepted through-fault protection curves. Also covered are the principles of coordination as they relate to the proper selection of the primary-side fuse and power fuses and the principles underlying the protection of load-side conductors and cables. The critical nature of secondary fault protection on small three-phase transformers used on industrial, commercial, and institutional power systems, as well as small-to-medium size three-phase power transformers used in utility substations is emphasized, in view of the long lead time and expense involved in replacing these transformers. In contrast, no special protection recommendations are made for small-kVA overhead distribution transformers, since they are not considered likely to experience secondary faults, and the rare faults that do occur will not likely be detected and cleared by the primary fuse. Also of importance is the fact that these transformers are inexpensive and readily available. Overall, large fuse rating, used in combination with a tank-mounted surge arrester is recommended, because it can provide better transformer protection than the smaller fuse ratings traditionally employed. 4 refs., 2 tabs., 4 figs.

A 3D Sphere Culture System Containing Functional Polymers for Large-Scale Human Pluripotent Stem Cell Production

Full Text Available Utilizing human pluripotent stem cells (hPSCs in cell-based therapy and drug discovery requires large-scale cell production. However, scaling up conventional adherent cultures presents challenges of maintaining a uniform high quality at low cost. In this regard, suspension cultures are a viable alternative, because they are scalable and do not require adhesion surfaces. 3D culture systems such as bioreactors can be exploited for large-scale production. However, the limitations of current suspension culture methods include spontaneous fusion between cell aggregates and suboptimal passaging methods by dissociation and reaggregation. 3D culture systems that dynamically stir carrier beads or cell aggregates should be refined to reduce shearing forces that damage hPSCs. Here, we report a simple 3D sphere culture system that incorporates mechanical passaging and functional polymers. This setup resolves major problems associated with suspension culture methods and dynamic stirring systems and may be optimal for applications involving large-scale hPSC production.

Dynamical links between small- and large-scale mantle heterogeneity: Seismological evidence

Frost, Daniel A.; Garnero, Edward J.; Rost, Sebastian

2018-01-01

We identify PKP • PKP scattered waves (also known as P‧ •P‧) from earthquakes recorded at small-aperture seismic arrays at distances less than 65°. P‧ •P‧ energy travels as a PKP wave through the core, up into the mantle, then scatters back down through the core to the receiver as a second PKP. P‧ •P‧ waves are unique in that they allow scattering heterogeneities throughout the mantle to be imaged. We use array-processing methods to amplify low amplitude, coherent scattered energy signals and resolve their incoming direction. We deterministically map scattering heterogeneity locations from the core-mantle boundary to the surface. We use an extensive dataset with sensitivity to a large volume of the mantle and a location method allowing us to resolve and map more heterogeneities than have previously been possible, representing a significant increase in our understanding of small-scale structure within the mantle. Our results demonstrate that the distribution of scattering heterogeneities varies both radially and laterally. Scattering is most abundant in the uppermost and lowermost mantle, and a minimum in the mid-mantle, resembling the radial distribution of tomographically derived whole-mantle velocity heterogeneity. We investigate the spatial correlation of scattering heterogeneities with large-scale tomographic velocities, lateral velocity gradients, the locations of deep-seated hotspots and subducted slabs. In the lowermost 1500 km of the mantle, small-scale heterogeneities correlate with regions of low seismic velocity, high lateral seismic gradient, and proximity to hotspots. In the upper 1000 km of the mantle there is no significant correlation between scattering heterogeneity location and subducted slabs. Between 600 and 900 km depth, scattering heterogeneities are more common in the regions most remote from slabs, and close to hotspots. Scattering heterogeneities show an affinity for regions close to slabs within the upper 200 km of the

There is a strong domestic market for charcoal in Thailand and many developing countries. Charcoal is usually made from biomass materials in small scale, simple kilns. Traditional charcoal making kilns adopts a process that is very inefficient, and damaging to the environment. In this work, an alternative charcoal reactor based on natural draft, pyrolysis gas burning concept was proposed and demonstrated. Tests with longan woods and bamboo showed that good quality charcoal can be produced in shorter time with lower pollution emissions, compared with traditional kilns. The proposed carbonizer proved to be suitable for small scale, charcoal production in rural area.

High-Efficiency Small-Scale Combined Heat and Power Organic Binary Rankine Cycles

Small-CHP (Combined Heat and Power) systems are generally considered a valuable technological option to the conventional boilers, in a technology developed context. If small-CHP systems are associated with the use of renewable energies (biomass, for example) they could play an important role in distributed generation even in developing countries or, in any case, where there are no extensive electricity networks. Traditionally the considered heat engines for micro- or mini-CHP are: the gas eng...

A Cultural Evolution Approach to Digital Media.

Acerbi, Alberto

2016-01-01

Digital media have today an enormous diffusion, and their influence on the behavior of a vast part of the human population can hardly be underestimated. In this review I propose that cultural evolution theory, including both a sophisticated view of human behavior and a methodological attitude to modeling and quantitative analysis, provides a useful framework to study the effects and the developments of media in the digital age. I will first give a general presentation of the cultural evolution framework, and I will then introduce this more specific research program with two illustrative topics. The first topic concerns how cultural transmission biases, that is, simple heuristics such as "copy prestigious individuals" or "copy the majority," operate in the novel context of digital media. The existence of transmission biases is generally justified with their adaptivity in small-scale societies. How do they operate in an environment where, for example, prestigious individuals possess not-relevant skills, or popularity is explicitly quantified and advertised? The second aspect relates to fidelity of cultural transmission. Digitally-mediated interactions support cheap and immediate high-fidelity transmission, in opposition, for example, to oral traditions. How does this change the content that is more likely to spread? Overall, I suggest the usefulness of a "long view" to our contemporary digital environment, contextualized in cognitive science and cultural evolution theory, and I discuss how this perspective could help us to understand what is genuinely new and what is not.

Analysis of small scale turbulent structures and the effect of spatial scales on gas transfer

Science.gov (United States)

Schnieders, Jana; Garbe, Christoph

2014-05-01

The exchange of gases through the air-sea interface strongly depends on environmental conditions such as wind stress and waves which in turn generate near surface turbulence. Near surface turbulence is a main driver of surface divergence which has been shown to cause highly variable transfer rates on relatively small spatial scales. Due to the cool skin of the ocean, heat can be used as a tracer to detect areas of surface convergence and thus gather information about size and intensity of a turbulent process. We use infrared imagery to visualize near surface aqueous turbulence and determine the impact of turbulent scales on exchange rates. Through the high temporal and spatial resolution of these types of measurements spatial scales as well as surface dynamics can be captured. The surface heat pattern is formed by distinct structures on two scales - small-scale short lived structures termed fish scales and larger scale cold streaks that are consistent with the footprints of Langmuir Circulations. There are two key characteristics of the observed surface heat patterns: 1. The surface heat patterns show characteristic features of scales. 2. The structure of these patterns change with increasing wind stress and surface conditions. In [2] turbulent cell sizes have been shown to systematically decrease with increasing wind speed until a saturation at u* = 0.7 cm/s is reached. Results suggest a saturation in the tangential stress. Similar behaviour has been observed by [1] for gas transfer measurements at higher wind speeds. In this contribution a new model to estimate the heat flux is applied which is based on the measured turbulent cell size und surface velocities. This approach allows the direct comparison of the net effect on heat flux of eddies of different sizes and a comparison to gas transfer measurements. Linking transport models with thermographic measurements, transfer velocities can be computed. In this contribution, we will quantify the effect of small scale

Concentrated fed-batch cell culture increases manufacturing capacity without additional volumetric capacity.

2016-01-10

Biomanufacturing factories of the future are transitioning from large, single-product facilities toward smaller, multi-product, flexible facilities. Flexible capacity allows companies to adapt to ever-changing pipeline and market demands. Concentrated fed-batch (CFB) cell culture enables flexible manufacturing capacity with limited volumetric capacity; it intensifies cell culture titers such that the output of a smaller facility can rival that of a larger facility. We tested this hypothesis at bench scale by developing a feeding strategy for CFB and applying it to two cell lines. CFB improved cell line A output by 105% and cell line B output by 70% compared to traditional fed-batch (TFB) processes. CFB did not greatly change cell line A product quality, but it improved cell line B charge heterogeneity, suggesting that CFB has both process and product quality benefits. We projected CFB output gains in the context of a 2000-L small-scale facility, but the output was lower than that of a 15,000-L large-scale TFB facility. CFB's high cell mass also complicated operations, eroded volumetric productivity, and showed our current processes require significant improvements in specific productivity in order to realize their full potential and savings in manufacturing. Thus, improving specific productivity can resolve CFB's cost, scale-up, and operability challenges. Copyright © 2015 Elsevier B.V. All rights reserved.

Small-scale upgrading and refinement of biogas is a report which aims to compile the state of knowledge in small-scale biogas upgrading. The project have been a collaboration with Agrovaest and Energy Farm and was funded by the Foundation for Agricultural Research, Western Goetaland and the Agriculture Department. The technology available for small scale upgrade has been examined from the technical and economic standpoint. An economic comparison has been made and the production of upgraded biogas has been estimated for different raw gas flows. The work also contains information related to biogas production, upgrading and a comparison of liquid biogas, DME and Ecopar-diesel

The natural selection of organizational and safety culture within a small to medium sized enterprise (SME).

Brooks, Benjamin

2008-01-01

Small to Medium Sized Enterprises (SMEs) form the majority of Australian businesses. This study uses ethnographic research methods to describe the organizational culture of a small furniture-manufacturing business in southern Australia. Results show a range of cultural assumptions variously 'embedded' within the enterprise. In line with memetics - Richard Dawkin's cultural application of Charles Darwin's theory of Evolution by Natural Selection, the author suggests that these assumptions compete to be replicated and retained within the organization. The author suggests that dominant assumptions are naturally selected, and that the selection can be better understood by considering the cultural assumptions in reference to Darwin's original principles and Frederik Barth's anthropological framework of knowledge. The results are discussed with reference to safety systems, negative cultural elements called Cultural Safety Viruses, and how our understanding of this particular organizational culture might be used to build resistance to these viruses.

The influence of Christian conversion in Mapuche traditional medicine in Temuco, Chile: toward a cultural syncretism or a form of ideological assimilation?

Science.gov (United States)

Torri, Maria Costanza

2013-12-01

The Mapuche communities living in the urban areas of Chile have undergone radical cultural changes due to Christian conversion. This article analyzes the influence of these changes on the Mapuche ideas and practices of the traditional healers (machi) and patients in Temuco (IX Region), Chile, and the changes and adaptations in the perceptions of healing practices and rituals by the patients. The paper shows how, despite some evident challenges, the encounter with the religion of Christianity can create a process of cultural and spiritual syncretism and push traditional medicine toward an increased specialization in the therapeutic practices.

Health status and occupational risk factors in Greek small fisheries workers.

Frantzeskou, Elpida; Jensen, Olaf Chresten; Linos, Athena

2016-01-01

Fishing is an extremely dangerous occupational activity that predisposes to occupational diseases and accidents. Greece, with about 16,000 km of coastline and its unique morphological characteristics with small islands and peninsulas, represents a strong proof of its great tradition in the fisheries sector since ancient times. The aim of the study was to examine the health status and the health risk factors present in Greek fishery workers, by exploring their working environment, thus providing a current baseline for documentation of the needs for prevention and health promotion. An interviewer-administered questionnaire was distributed in 2013 to a random sample of 172 professional small-scale fishermen of the Evros district in North-Eastern Greece. Eighty-eight per cent worked in coastal fisheries and 73% were using small fishing vessels, less than 10 m in length overall. Health disorders included musculoskeletal, cardiovascular and visual problems and to a minor degree by hearing, dermatologic and respiratory problems in all age groups. Seventy per cent had experienced at least one occupational accident. Heavy smoking and daily alcohol consumption was seen among nearly half of the fishermen. The health effects observed are causally related to the work process exposures on board and to diet, smoking, and lack of exercise. This in turn relates to the specific working conditions, the culture and level of education in small-scale fishing that need to be taken into consideration together in the prevention programmes.

Full Text Available Abstract Background Accurate assessment of self-reports of sexual behaviours is vital to the evaluation of HIV prevention and family planning interventions. This investigation was to determine the cross-cultural suitability of the Condom Use Self Efficacy Scale (CUSES originally developed for American adolescents and young adults by examining the structure and psychometric properties. Method A self-administered cross-sectional survey of a convenient sample of 511 participants from a private university in Ghana with mean age 21.59 years. Result A Principal Component Analysis with varimax rotation identified a 14 item scale with four reliable factors labelled Appropriation (Cronbach alpha = .85, Assertive (Cronbach alpha = .90, Pleasure and Intoxicant (Cronbach alpha = .83, and STDs (Cronbach alpha = .81 that altogether explained 73.72% of the total variance. The scale correlated well with a measure of condom use at past sexual encounter (r = .73, indicating evidence of construct and discriminatory validity. The factor loadings were similar to the original CUSES scale but not identical suggesting relevant cultural variations. Conclusion The 14 item scale (CUSES-G is a reliable and valid instrument for assessing condom use self efficacy. It is culturally appropriate for use among Ghanaian youth to gauge actual condom use and to evaluate interventions meant to increase condom use. Finally, the study cautioned researchers against the use of the original CUSES without validation in African settings and contexts.

Full Text Available In our study we examine teaching mother tongue through faire and folk tales from the perspectives of recognizing clichés in fairy tales and myths, idiomatic phrases which work as morals, proverbs and very specific phrases of traditional tales’. We suggest that formulaic language can be involved in children’s language games at school and become a methodological tool for innovative approaches in Language and Teaching especially at the primary education. We search the sources from Greek traditional tales that could serve as teaching material for this option of teaching formulaic language in mother tongue. Cultural and geographical implications of the examples applied are noted as a suggestion for further discussion.

Cross-cultural differences in social desirability scales: Influence of cognitive ability

2015-07-01

Full Text Available Orientation: The use of personality tests for selection and screening has been consistently criticised resulting from the risk of socially desirable responding amongst job applicants. Research purpose: This study examined the magnitude of culture and language group meanscore differences amongst job applicants and the moderating effect of race on the relationship between social desirability and cognitive ability. Motivation for the study: The influence of cognitive ability and potential race and ethnic group differences in social desirability scale scores, which can lead to disproportional selection ratios, has not been extensively researched in South Africa. Research design, approach and method: A quantitative, cross-sectional research design, based on secondary datasets obtained from the test publisher, was employed. The dataset consisted of 1640 job applicants across industry sectors. Main findings: Moderated multiple regression analyses revealed that the relationship between social desirability and general reasoning was moderated by culture and language, with group differences in social desirability being more pronounced at the low general reasoning level. This suggests that social desirability scales may be an ambiguous indicator of faking as the scales may indicate tendency to fake, but not the ability to fake, that is likely to be connected to the level of cognitive ability of the respondent. Practical/managerial implications: Individual differences in social desirability are not fully explained by cognitive ability as cultural differences also played a role. Responding in a certain manner, reflects a level of psychological sophistication that is informed by the level of education and socio-economic status. In relation to selection practice, this study provided evidence of the potentially adverse consequences of using social desirability scales to detect response distortion.

At present rapid progress is being made in the application of soft x-ray lasers to fields such as microscopy and microlithography. A critical factor in the range of suitable applications is the scale and hence cost of the soft x-ray lasers. At Princeton, gain at 183 angstrom has been obtained with relatively low pump laser energies (as low as 6J) in a ''portable'' small-scale soft x-ray laser system. We will also discuss aspects of data interpretation and pitfalls to be avoided in measurements of gain in such systems. 14 refs., 7 figs

Leadership solves collective action problems in small-scale societies

Glowacki, Luke; von Rueden, Chris

2015-01-01

Observation of leadership in small-scale societies offers unique insights into the evolution of human collective action and the origins of sociopolitical complexity. Using behavioural data from the Tsimane forager-horticulturalists of Bolivia and Nyangatom nomadic pastoralists of Ethiopia, we evaluate the traits of leaders and the contexts in which leadership becomes more institutional. We find that leaders tend to have more capital, in the form of age-related knowledge, body size or social connections. These attributes can reduce the costs leaders incur and increase the efficacy of leadership. Leadership becomes more institutional in domains of collective action, such as resolution of intragroup conflict, where collective action failure threatens group integrity. Together these data support the hypothesis that leadership is an important means by which collective action problems are overcome in small-scale societies. PMID:26503683

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.

Awe, the diminished self, and collective engagement: Universals and cultural variations in the small self.

Bai, Yang; Maruskin, Laura A; Chen, Serena; Gordon, Amie M; Stellar, Jennifer E; McNeil, Galen D; Peng, Kaiping; Keltner, Dacher

2017-08-01

Awe has been theorized as a collective emotion, one that enables individuals to integrate into social collectives. In keeping with this theorizing, we propose that awe diminishes the sense of self and shifts attention away from individual interests and concerns. In testing this hypothesis across 6 studies (N = 2137), we first validate pictorial and verbal measures of the small self; we then document that daily, in vivo, and lab experiences of awe, but not other positive emotions, diminish the sense of the self. These findings were observed across collectivist and individualistic cultures, but also varied across cultures in magnitude and content. Evidence from the last 2 studies showed that the influence of awe upon the small self accounted for increases in collective engagement, fitting with claims that awe promotes integration into social groups. Discussion focused on how the small self might mediate the effects of awe on collective cognition and behavior, the need to study more negatively valenced varieties of awe, and other potential cultural variations of the small self.

The case for small-scale domestic cannabis cultivation.

Science.gov (United States)

Decorte, Tom

2010-07-01

The shift to (inter)regional production, trade and domestic cultivation has become an irreversible international trend. Until now, the focus of most empirical work has been on large-scale, commercially oriented and professionally organized segments of the cannabis industry, often based on police data and on the perspective of law enforcement agencies. This paper offers a review of recent Dutch-language research that focuses on cannabis cultivation. Empirical studies were identified through literature searches using relevant search terms and Web of Science, Elin, Social Science Research Network and Elsevier ScienceDirect. The paper presents the main findings of Dutch and Belgian empirical work on the factors that stimulated the import substitution process on the cannabis market, aspects related to quality and potency issues, typologies of cannabis growers, and (unintended) effects of pursued policies. In the light of this (selective) review the author offers some commentary and analysis concerning the claims made by different stakeholders, and concludes with some reflections on future research and on policy implications. The author outlines the importance of small-scale, independent or ideologically oriented cannabis cultivation as an under-researched market segment. The author also makes a case for greater toleration of small-scale cannabis cultivation, to secure the least worst of cannabis markets. Copyright (c) 2010 Elsevier B.V. All rights reserved.

Reassessing the "traditional background hypothesis" for elevated MMPI and MMPI-2 Lie-scale scores.

Science.gov (United States)

Rosen, Gerald M; Baldwin, Scott A; Smith, Ronald E

2016-10-01

The Lie (L) scale of the Minnesota Multiphasic Personality Inventory (MMPI) is widely regarded as a measure of conscious attempts to deny common human foibles and to present oneself in an unrealistically positive light. At the same time, the current MMPI-2 manual states that "traditional" and religious backgrounds can account for elevated L scale scores as high as 65T-79T, thereby tempering impression management interpretations for faith-based individuals. To assess the validity of the traditional background hypothesis, we reviewed 11 published studies that employed the original MMPI with religious samples and found that only 1 obtained an elevated mean L score. We then conducted a meta-analysis of 12 published MMPI-2 studies in which we compared L scores of religious samples to the test normative group. The meta-analysis revealed large between-study heterogeneity (I2 = 87.1), L scale scores for religious samples that were somewhat higher but did not approach the upper limits specified in the MMPI-2 manual, and an overall moderate effect size (d¯ = 0.54, p < .001; 95% confidence interval [0.37, 0.70]). Our analyses indicated that religious-group membership accounts, on average, for elevations on L of about 5 t-score points. Whether these scores reflect conscious "fake good" impression management or religious-based virtuousness remains unanswered. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Redesigning care has been proposed as a lever for improving chronic illness care. Within primary care, diabetes care is the most widespread example of restructured integrated care. Our goal was to assess to what extent important aspects of restructured care such as multidisciplinary teamwork and different types of organizational culture are associated with high quality diabetes care in small office-based general practices. We conducted cross-sectional analyses of data from 83 health care professionals involved in diabetes care from 30 primary care practices in the Netherlands, with a total of 752 diabetes mellitus type II patients participating in an improvement study. We used self-reported measures of team climate (Team Climate Inventory) and organizational culture (Competing Values Framework), and measures of quality of diabetes care and clinical patient characteristics from medical records and self-report. We conducted multivariate analyses of the relationship between culture, climate and HbA1c, total cholesterol, systolic blood pressure and a sum score on process indicators for the quality of diabetes care, adjusting for potential patient- and practice level confounders and practice-level clustering. A strong group culture was negatively associated to the quality of diabetes care provided to patients (beta = -0.04; p = 0.04), whereas a more 'balanced culture' was positively associated to diabetes care quality (beta = 5.97; p = 0.03). No associations were found between organizational culture, team climate and clinical patient outcomes. Although some significant associations were found between high quality diabetes care in general practice and different organizational cultures, relations were rather marginal. Variation in clinical patient outcomes could not be attributed to organizational culture or teamwork. This study therefore contributes to the discussion about the legitimacy of the widespread idea that aspects of redesigning care such as teamwork and culture

To culturally adapt the Family Quality of Life Scale to the Brazilian Portuguese version and evaluate the instrument reliability and family quality of life of those who have children with hearing loss. The process of cultural adaptation of the scale followed the steps of the Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measure. It was conducted in three stages: translation, back translation, and application in a pilot sample, as a way to check the comprehension difficulties of the items. After it had been completed, it was administered to 41 families who have children with hearing loss and, with their results, the quality of life and reliability were analyzed based on the Cronbach's alpha statistical test. In the first version (translation), among the 25 items, there were differences between the translators only in four items; after the corrections, the second version was done (back translation), in which other four more differences were found. Finally, after the final corrections, the last version was developed and used in the pilot sample without differences. Thus, it was applied to families with deaf children, who believe to be satisfied as to their quality of life. The Cronbach's alpha test found that the scale shows a satisfactory reliability. The Brazilian Portuguese version of the Family Quality of Life Scale is a tool of easy use and satisfactory reliability. The families are satisfied with their family quality of life.

Large-scale Assessment Yields Evidence of Minimal Use of Reasoning Skills in Traditionally Taught Classes

Large-scale assessment data from Texas Tech University yielded evidence that most students taught traditionally in large lecture classes with online homework and predominantly multiple choice question exams, when asked to answer free-response (FR) questions, did not support their answers with logical arguments grounded in physics concepts. In addition to a lack of conceptual understanding, incorrect and partially correct answers lacked evidence of the ability to apply even lower level reasoning skills in order to solve a problem. Correct answers, however, did show evidence of at least lower level thinking skills as coded using a rubric based on Bloom's taxonomy. With the introduction of evidence-based instruction into the labs and recitations of the large courses and in a small, completely laboratory-based, hands-on course, the percentage of correct answers with correct explanations increased. The FR format, unlike other assessment formats, allowed assessment of both conceptual understanding and the application of thinking skills, clearly pointing out weaknesses not revealed by other assessment instruments, and providing data on skills beyond conceptual understanding for course and program assessment.

Electronic medical records are increasingly common in medical practice. The secondary use of medical records has become increasingly important. It relies on the ability to retrieve the complete information about desired patient populations. How to effectively and accurately retrieve relevant medical records from large- scale medical big data is becoming a big challenge. Therefore, we propose an efficient and robust framework based on cloud for large-scale Traditional Chinese Medical Records (TCMRs) retrieval. We propose a parallel index building method and build a distributed search cluster, the former is used to improve the performance of index building, and the latter is used to provide high concurrent online TCMRs retrieval. Then, a real-time multi-indexing model is proposed to ensure the latest relevant TCMRs are indexed and retrieved in real-time, and a semantics-based query expansion method and a multi- factor ranking model are proposed to improve retrieval quality. Third, we implement a template-based visualization method for displaying medical reports. The proposed parallel indexing method and distributed search cluster can improve the performance of index building and provide high concurrent online TCMRs retrieval. The multi-indexing model can ensure the latest relevant TCMRs are indexed and retrieved in real-time. The semantics expansion method and the multi-factor ranking model can enhance retrieval quality. The template-based visualization method can enhance the availability and universality, where the medical reports are displayed via friendly web interface. In conclusion, compared with the current medical record retrieval systems, our system provides some advantages that are useful in improving the secondary use of large-scale traditional Chinese medical records in cloud environment. The proposed system is more easily integrated with existing clinical systems and be used in various scenarios. Copyright © 2017. Published by Elsevier Inc.

Modelling aggregation on the large scale and regularity on the small scale in spatial point pattern datasets

DEFF Research Database (Denmark)

Lavancier, Frédéric; Møller, Jesper

We consider a dependent thinning of a regular point process with the aim of obtaining aggregation on the large scale and regularity on the small scale in the resulting target point process of retained points. Various parametric models for the underlying processes are suggested and the properties...
