Cultivation of the brown alga Hizikia fusiformis (Harvey) Okamura: enhanced seedling production in tumbled culture

The reuse of holdfasts for regeneration of young seedlings or using wild juvenile plants as the seedling source has played the major role in commercial cultivation of the brown alga Hizikia fusiformis in East Asia over the past 20 years. The possibility of employing zygote-derived germlings for producing seedlings has been discussed in the literature, but has not yet become a reality. Three main obstacles have limited the use of zygotes as a main source of seedlings, (1) the dioecious nature of the algal life cycle which may lead to asynchronous male and female receptacle development and thus different timing of egg and spermatozoa expulsion, (2) the low attachment rate when using zygote-derived germlings with developed rhizoids from wild parental plants for seeding production, and (3) the problem of culturing young germlings in regions where water temperature is high in summer. In this investigation, shifting the timing of receptacle formation earlier than in nature was performed by tumbling the algae in a long-day tank (16-h light per day). Synchronization of egg and spermatozoa expulsion and thereafter fertilization were conducted in indoor tanks. Receptacle formation in constant long days could be shifted by 20 days earlier than in plants cultured on long lines in the open sea, or I month earlier than in plants growing on intertidal rocks. Synchronized expulsion of eggs and spermatozoon led to a high rate of fertilization. This was achieved by tumbling the male and female receptacle-bearing branchlets in the same tank at low density in high irradiance. In two independent trials, a total of 1,400,000 zygote-derived germlings were obtained from 620 g (fresh weight) female sporophytes. The germlings shed from the receptacles were at an identical developmental stage indicating high synchronization of expulsion of eggs and spermatozoon followed by fertilization. Approximately 63% ( +/-9.6%) of the germlings were shed from the receptacle between 16 and 24 It after fertilization and 20% ( +/-11.9%) remained on the receptacle for 3 days after fertilization. Germlings were seeded on string collectors before rhizoids started to elongate and the attachment efficiency was enhanced. Young seedlings reached 800 ( +/-50) mum in length in 25 days at 25 degreesC before they were transferred to open sea cultivation. These results provide the basis of a practical way of seedling production by use of zygote-derived germlings in the commercial cultivation of Hizikia fusiformis.

An ethnographic interpretation of the work environment within a creative culture in the advertising sector.

Purpose and rationale The purpose of the exploratory research is to provide a deeper understanding of how the work environment enhances or constrains organisational creativity (creativity and innovation) within the context of the advertising sector. The argument for the proposed research is that the contemporary literature is dominated by quantitative research instruments to measure the climate and work environment across many different sectors. The most influential theory within the extant literature is the componential theory of organisational creativity and innovation and is used as an analytical guide (Amabile, 1997; Figure 8) to conduct an ethnographic study within a creative advertising agency based in Scotland. The theory suggests that creative people (skills, expertise and task motivation) are influenced by the work environment in which they operate. This includes challenging work (+), work group supports (+), supervisory encouragement (+), freedom (+), sufficient resources (+), workload pressures (+ or -), organisational encouragement (+) and organisational impediments (-) which is argued enhances (+) or constrains (-) both creativity and innovation. An interpretive research design is conducted to confirm, challenge or extend the componential theory of organisational creativity and innovation (Amabile, 1997; Figure 8) and contribute to knowledge as well as practice. Design/methodology/approach The scholarly activity conducted within the context of the creative industries and advertising sector is in its infancy and research from the alternative paradigm using qualitative methods is limited which may provide new guidelines for this industry sector. As such, an ethnographic case study research design is a suitable methodology to provide a deeper understanding of the subject area and is consistent with a constructivist ontology and an interpretive epistemology. This ontological position is conducive to the researcher’s axiology and values in that meaning is not discovered as an objective truth but socially constructed from multiple realties from social actors. As such, ethnography is the study of people in naturally occurring settings and the creative advertising agency involved in the research is an appropriate purposive sample within an industry that is renowned for its creativity and innovation. Qualitative methods such as participant observation (field notes, meetings, rituals, social events and tracking a client brief), material artefacts (documents, websites, annual reports, emails, scrapbooks and photographic evidence) and focused interviews (informal and formal conversations, six taped and transcribed interviews and use of Survey Monkey) are used to provide a written account of the agency’s work environment. The analytical process of interpreting the ethnographic text is supported by thematic analysis (selective, axial and open coding) through the use of manual analysis and NVivo9 software Findings The findings highlight a complex interaction between the people within the agency and the enhancers and constraints of the work environment in which they operate. This involves the creative work environment (Amabile, 1997; Figure 8) as well as the physical work environment (Cain, 2012; Dul and Ceylan, 2011; Dul et al. 2011) and that of social control and power (Foucault, 1977; Gahan et al. 2007; Knights and Willmott, 2007). As such, the overarching themes to emerge from the data on how the work environment enhances or constrains organisational creativity include creative people (skills, expertise and task motivation), creative process (creative work environment and physical work environment) and creative power (working hours, value of creativity, self-fulfilment and surveillance). Therefore, the findings confirm that creative people interact and are influenced by aspects of the creative work environment outlined by Amabile (1997; Figure 8). However, the results also challenge and extend the theory to include that of the physical work environment and creative power. Originality/value/implications Methodologically, there is no other interpretive research that uses an ethnographic case study approach within the context of the advertising sector to explore and provide a deeper understanding of the subject area. As such, the contribution to knowledge in the form of a new interpretive framework (Figure 16) challenges and extends the existing body of knowledge (Amabile, 1997; Figure 8). Moreover, the contribution to practice includes a flexible set of industry guidelines (Appendix 13) that may be transferrable to other organisational settings.

Upin & Ipin: Promoting malaysian culture values through animation

Malaysian children lately have been exposed or influenced heavily by digital media entertainment. The rise of such entertainment tends to drive them away from understanding and appreciating the values of Malaysian culture. Upin and Ipin animation has successfully promoted Malaysian folklore culture and has significantly portrayed the art of Malaysian values including Islamic values by providing the platform for harmonious relationship among different societies or groups or religious backgrounds. The focus of this research is to look into the usage of Malaysian culture iconic visual styles such as backgrounds, lifestyles, character archetypes and narrative (storytelling). Therefore, we hope that this research will benefit the younger generation by highlighting the meaning and importance of implicit Malaysian culture.

“Islands” in Holocene forests: implications for forest openness, landscape clearance and “culture-steppe” species

Human activity has undoubtedly had a major impact on Holocene forested ecosystems, with the concurrent expansion of plants and animals associated with cleared landscapes and pasture, also known as 'culture-steppe'. However, this anthropogenic perspective may have underestimated the contribution of autogenic disturbance (e.g. wind-throw, fire), or a mixture of autogenic and anthropogenic processes, within early Holocene forests. Entomologists have long argued that the north European primary forest was probably similar in structure to pasture woodland. This idea has received support from the conservation biologist Frans Vera, who has recently strongly argued that the role of large herbivores in maintaining open forests in the primeval landscapes of Europe has been seriously underestimated. This paper reviews this debate from a fossil invertebrate perspective and looks at several early Holocene insect assemblages. Although wood taxa are indeed important during this period, species typical of open areas and grassland and dung beetles, usually associated with the dung of grazing animals, are persistent presences in many early woodland faunas. We also suggest that fire and other natural disturbance agents appear to have played an important ecological role in some of these forests, maintaining open areas and creating open vegetation islands within these systems. More work, however, is required to ascertain the role of grazing animals, but we conclude that fossil insects have a significant contribution to make to this debate. This evidence has fundamental implications in terms of how the palaeoecological record is interpreted, particularly by environmental archaeologists and palaeoecologists who may be more interested in identifying human-environment interactions rather than the ecological processes which may be preserved within palaeoecological records.

Places making: participatory construction of scientifi c culture cities

In the framework of the European project Platform of Local Authorities and Communicators Engaged in Science (PLACES), we analyse the articulations between scientifi c communication, public perception of science, processes of citizen participation and apropiation of space, based on a case study of the inhabitants of Teruel city, Autonomous Community of Aragon, Spain. On the interrelationships between these issues, there are a number of contradictions, such as the difference between a high interest for information about science and technology and a low level of recognition and interaction with local institutions involved in those activities, the complex conceptualization of scientifi c space in relation to the “public-private” pair, or an articulation of a claiming civic rethoric and an insuffi cient co-responsibility. We conclude that, in a local context, the dimension of territoriality and, in particular, the identifi cation with the town, is a central mediation for activating citizen participation as part of processes of appropriation of space for setting up cities of scientifi c culture.

Towards a person-centred ‘culture’: the use of community development approaches in the Independent Youth Counselling Service in West Belfast

This paper is drawn from a qualitative study of clients, counsellors and the supervisors views of the value and impact of the Independent Youth Counselling Service (IYCS) in West Belfast. Data collection combined semi-structured interviews, focus groups and an open-ended questionnaire. The findings indicate the significance of factors above and beyond the person-centred counselling experience, in maximising the potential for growth and development for clients and counsellors. This holistic approach to counselling service provision employs a body of community development processes, which collectively combine to embed the counselling service in a complementary principled approach. This paper explores how these community development features bolster the counselling experience to promote a culture of person-centeredness, thereby increasing the empowerment of the client.

Évaluation du potentiel de croissance et de rendement d’une culture de tomates biologiques cultivées dans une serre climatisée à l’aide d’un système géothermique

Ce projet visait à comparer les effets agronomiques d’une serre de tomates biologiques semi-fermée utilisant un système de climatisation par géothermie comparativement à une serre ouverte. Deux serres de 228 et 230 m2 ont été équipées d’un système d’échangeur d’air avec géothermie qui refroidissait et déshumidifiait l’air (serre semi-fermée) et d’un système de ventilation naturelle (serre témoin). Ces dernières ont été comparées au cours des années 2012 et 2013 entre lesquels les traitements ont été permutés. Les variables mesurées étaient les paramètres de croissance des plants ainsi que le rendement, le calibre des fruits et les propriétés physico-chimiques des tomates. Les résultats ont démontré que le système de climatisation n’a pas eu d’effets significatifs sur la croissance des plants, la qualité des fruits ainsi que le rendement. Les deux serres avaient des cibles de concentration en CO2 comprises entre 450 µL L-1 et 1000 µL L-1 selon l’ensoleillement. Les quantités de CO2 injectées ont été de 11 kg/m2 et 15 kg/m2 respectivement en 2012 et 2013 dans la serre semi-fermée alors qu’elles ont été de 24 kg/m2 et 25 kg/m2 dans la serre témoin. Bien qu’ayant nécessité moins d’injection, la serre semi-fermée a permis de conserver des concentrations en CO2 de 638 µL L-1 en 2012 et de 593 µL L-1 en 2013. Ces concentrations sont plus élevées que celles obtenues dans la serre témoin qui étaient respectivement de 385 µL L-1 et 486 µL L-1 en 2012 et 2013. De ce fait, le coût monétaire associé à l’enrichissement carboné a été de 1,6 à 2,0 fois plus élevé dans la serre témoin que dans la serre semi-fermée.

An exploratory study of how a Korean chaebol’s learning culture facilitates customer service

This paper explains how the organizational learning concept is used by managers in a global Korean company to promote group work, information sharing and an open communication style in order to produce a high level of customer service. Previously collected data from a set of in-depth personal interviews undertaken with three senior managers in a Korean electronics company were analyzed and interpreted using the grounded theory approach, and a number of propositions are put forward. The research findings show that managers in a chaebol deploy organizational learning to identify skilled and knowledgeable staff, and improve the organization’s capability by placing emphasis on developing harmonious, mutually oriented relationships that permeate throughout the organization. Top management demand that staff identify with government economic objectives and align the organization’s strategy accordingly so that the products produced are marketable. To achieve this, the organization fosters continual interaction among managers throughout the organization’s hierarchy. The chaebol’s organizational learning model encapsulates a “corollary” (continual communication) and “tools” (cultural influence and relationship management), and manifests in a unique strategy that allows management systems to evolve naturally.

A Migrant Culture on Display: The French Migrant and French Gastronomy in London (19th – 21st centuries)

The large contemporary French migrant population – estimated by the French Consulate at around 300,000–400,000 in the UK, the majority living in London and the South-East – remains ‘absent’ from studies on migration, and, in a study of migrant food history in Britain, is considered not to have left traces as a migrant community. Over the centuries, the presence of various French communities in London has varied significantly as far as numbers are concerned, but what does not change is their simultaneous ‘visibility’ and ‘invisibility’ in accounts of the history of the capital: even when relatively ‘visible’ at certain historical moments, they still often remain hidden in its histories. At times the French in London are described as a ‘sober, well-behaved […] and law-abiding community’; at other times they ‘appeared as a foreign body in the city’. This article reflects on the dynamics at play between a migrant culture associated with high cultural capital (so much so that is often emulated by those who are not French) and the host culture perception of and relationship to it, in order to consider what this may ‘mean’ for the French (and Francophone) migrant experience. French gastronomy and culinary knowledge is taken as an example of material culture and of cultural capital ‘on display’ specifically in the activity of dining out, especially in French restaurants, or in those influenced by French gastronomy. The social activity of dining out is replete with displays of knowledge (linguistic, culinary), of cultural literacy, of modes of behaviour, of public identity, and of rituals strictly codified in both migrant and host cultures. Dining out is also an emotional and politically-charged activity, fraught with feelings of suspicion (what is in the food? what does the chef get up to in the kitchen?) and of anxieties and tensions concerning status, class and gender distinctions. This article considers the ways in which the migrant French citizen of London may be considered as occupying an ambiguous position at different times in history, simultaneously possessing cultural capital and needing to negotiate complex cultural encounters in the connections between identity and the symbolic status of food in food production, food purveying and food consumption.

Student Perceptions of Discretion in Discipline: Seeking Resolution and Restoration in a Punitive Culture

This study examined high school student perceptions of discretion utilized by educators in high school disciplinary proceedings. Using a sample of 6 high school students who had experienced differing levels of formal discipline, the study investigated the discretionary factors that influence an educator's decision making. The study was a generic qualitative study where the primary source of data collection was open-ended interviews to ensure the integrity of the research as a study of student voices and perceptions. Journaling was also employed to record observations and to identify researcher assumptions. The data were analyzed employing aspects of a grounded theory approach. The findings were coded to reveal 5 areas high school students identified in relation to discipline and discretion: punitive discipline versus problem resolution, effective processes, educator discretion, student discretion, and the student-educator relationship. The final discussion highlights the need for a community vision for high school discipline in order to channel discretion and to uphold students' best interests. Restorative justice is proposed as a feasible vision for high school discipline, whereby participants' responses are measured against a restorative paradigm.

Conserver ou restaurer? La dialectique de l’œuvre architecturale : histoire d'un débat qui a contribué à la formation de la culture de la conservation du patrimoine bâti

La question de recherche « Conserver ou restaurer ? » est le point de départ d’une aventure invitant le lecteur à répondre à qu’est-ce qui oriente nos interventions en matière de conservation du patrimoine bâti. Sachant que ces positions rivales ont toutes une prétention à la vérité, cette thèse fait l’hypothèse d’une médiation entre les deux approches en clarifiant ses différentes interprétations. À partir d'un regard critique de la théorie de Cesare Brandi fondée sur la dialectique historique-artistique de l’œuvre d’art ainsi que d'une réflexion sur la nature fonctionnelle de l’œuvre architecturale, cette thèse démontre qu’il n’y a pas lieu a priori de donner une prédominance à l’une des deux options, ni à établir une échelle de valeurs prédéterminées, mais dévoile un dénominateur commun qui est le temps. Ce dernier ne se restreint pas au passé et au présent, mais implique la puissance destructrice du temps de la nature et le temps historique fondé sur un présent durable riche du passé et ouvert sur l'avenir. Les résultats de la recherche révèlent enfin un dialogue possible entre nos deux alternatives, en proposant une éthique disciplinaire axée sur la dialectique du temps. Savoir « quand conserver ou quand restaurer » demande la reconnaissance de ce que l’on retient de plus significatif à travers l’existence de l’œuvre. Situer cette signification dans un passé révolu désigne l’œuvre comme témoignage d’un temps passé, en lui reconnaissant sa fonction mémorielle ou remémorative ; d’où l’approche à prédominance conservative visant à faire reculer la puissance destructrice du temps de la nature et à préserver le témoignage matériel de la dégradation. Au contraire, situer cette signification dans un présent vivant, c’est reconnaître sa vocation identitaire destinée à la représentation d’une culture ; d’où l’approche à prédominance restaurative (ré-intégrative) fondée sur le temps historique, d’un présent durable riche du passé et ouvert sur l'avenir visant à en révéler le sens. En bref, en ce qui concerne tout le patrimoine bâti, on ne peut parler que d’une dialectique fondamentale issue de la nature même de ces œuvres, à interpréter sous leur fonction mémorielle et leur vocation identitaire. Par conséquent, conserver ou restaurer devraient être réinterprétés par préserver la mémoire ou révéler l’identité. Ainsi, la conservation et la restauration ne doivent plus être entendues comme deux options antagonistes, mais comme deux modalités d’interprétation au service de la médiation de l’œuvre architecturale à travers le temps.

Culture d'OGM dans un marché unique : Système d'autorisation centralisée versus choix des États membres

Malgré l’incertitude quant à leur sécurité à l’égard des personnes et de l’environnement, les cultures génétiquement modifiées (GM) ont été largement diffusées à travers le monde. En outre, dans de nombreux pays la coexistence des cultures GM avec les systèmes conventionnels de production et les systèmes de production biologique est habituelle. Dans l’Union européenne (UE), cependant, l’utilisation de cette technologie a soulevé d’importantes questions. Ces réserves sont reflétées dans le développement d’un cadre réglementaire particulièrement restrictif articulé autour d’une procédure unique d’approbation de ces cultures. De la même manière, le débat sur la coexistence des cultures GM avec la production agricole conventionnelle et la production biologique a été particulièrement animé dans l’UE. La première section de ce travail est consacrée à examiner comment, du fait de la complexité des nouvelles technologies, il est nécessaire, du point de vue régulateur, de faire face à des situations dans lesquelles les scientifiques ne peuvent encore fournir aucune réponse précise. Dans ce contexte, le principe de précaution est invoqué afin de limiter les dangers potentiels, mais ceci est sans préjudice des questions qui restent encore ouvertes sur la portée et la nature de ce principe. En tant que manifestations précises de ce principe de précaution, deux aspects sont abordés dans les secondes et troisièmes parties de ce travail. Nous analysons, d’abord, la procédure d’autorisation des produits GM dans l’UE, procédure spécifique basée sur le principe de précaution dans laquelle soit les institutions communautaires soit les autorités des États membres jouent un rôle important. Par rapport à ce cadre très réglementé de l’UE, la troisième partie examine le degré d’intervention des États membres. Ceci se manifeste principalement dans la possibilité d’adopter certaines clauses de sauvegarde pour limiter l’expansion des cultures GM ainsi que dans la réglementation de la coexistence des cultures GM avec les cultures conventionnelles et la possibilité d’exclure de la culture des OGM certaines zones. Finalement, quelques conclusions sont données dans la quatrième partie.

Small and Closed vs. Large and Open: Some Lessons from Comparing Cuban to Colombian Agricultural Development

Comparing the experiences of selected Latin America and the Caribbean countries and their trajectories over the past 15 years offers rich insights into the dynamics and causes for not meeting the 2015 MDGs. They also offer clues for post-MDG strategies. Central to achieving sustainable growth are government policies able to support small and medium-sized farms and peasants, as they are crucial for the achievement of several goals, centrally: to achieve food security; to provide a sound and stable rural environment able to resist external (financial) shocks; to secure healthy food; to secure local food; and to protect vibrant and culturally rich local communities. This paper analyses and compares the most successful government policies to the least successful policies carried out over the last 15 years in selected Latin American and Caribbean countries and based on this analysis, offers strategies for more promising post-MDG politics, able to reduce poverty, reduce inequality, fight back informality, and achieve more decent work in poor countries.
