Understanding Neolithic Southern Levant: case studies of archaeological semiosis in action

I undersökningen tillämpas Charles Sanders Peirces semiotik för en kritisk granskning av arkeologiska tolkningsprocesser. Enligt Peirce bygger all betydelsegivning på tecken, som kan vara teckningar, föremål, ord, byggkonstruktioner eller egentligen vad som helst. Ett tecken är tredimensionellt: ”objekt”, ”tecken” och ”tolkning”. I sina tidiga skrifter definierar han tre grundtyper för tecknet, Index, Icon och Symbol. De grundläggande definitionerna i Peirces semiotik blir till ett slags lins. När den placeras på skrifter av en arkeolog som uttolkar tecken, framträder deras inre uppbyggnad, motiveringar och logiska konsekvens klart. Att beakta är, att denna bok är lika lite avsedd att utgöra en systematisk klarläggning av den arkeologiska semiotiken, som en omfattande beskrivning av symboliken i det neolitiska Mellanöstern. Analysen är deskriptiv och inte avsedd att utvärdera tolkningarnas riktighet, utan enbart att klarlägga hur arkeologen kommit fram till dessa. Som objekt har valts neolitiska södra Levanten, där viktiga fynd gällande denna i mänsklighetens kulturhistoria så betydelsefulla skede har gjorts. Förhistorien är intressant med tanke på arkeologisk semiosis, eftersom uttolkaren av en symbol inte kan stöda sig på textfynd, utan måste på annat sätt upptäcka vad ett föremål eller en byggnad betytt för sin upphovsman. Att upptäcka en trovärdig betydelse är ofta en mycket svår och understundom rentav omöjlig uppgift. Efter att förhållandet mellan semiotik och arkeologi dryftats analyseras i boken John Garstangs och Kathleen M. Kenyons grundläggande tolkningar i Jeriko, Denise-Schmandt Besserats jämförande analyser för uttolkningen av \'Ain Ghazalis kranium, Michele A. Millers kontextuella analys i Jarmuk samt David Lewis-Williams’ starkt strukturalistiska analys av betydelsen av fynden i \'Ain Ghazal. Peirces semiotik har använts som stöd för arkeologin i mycket mindre utsträckning än F. de Saussures lingvistiska ja strukturalistiska semiotik. I Mellanöstern har man hittills inte alls gjort det. Ingen av de forskare som behandlas i boken hänvisar själv till semiotik eller tecken. Logiken i uttolkningen av dessa undersökningar är mycket invecklad, och de av Peirce gestaltade processerna för betydelsegivning visar sig härvidlag utgöra en ytterst klargörande kritisk apparat.

Enhancing absorptive capacity in a non-research and development. An action research approach to converting individual observations into organisational awareness

The ability to recognize potential knowledge and convert it into business opportunities is one of the key factors of renewal in uncertain environments. This thesis examines absorptive capacity in the context of non-research and development innovation, with a primary focus on the social interaction that facilitates the absorption of knowledge. It proposes that everyone is and should be entitled to take part in the social interaction that shapes individual observations into innovations. Both innovation and absorptive capacity have been traditionally related to research and development departments and institutions. These innovations need to be adopted and adapted by others. This so-called waterfall model of innovations is only one aspect of new knowledge generation and innovation. In addition to this Science–Technology–Innovation perspective, more attention has been recently paid to the Doing–Using–Interacting mode of generating new knowledge and innovations. The amount of literature on absorptive capacity is vast, yet the concept is reified. The greater part of the literature links absorptive capacity to research and development departments. Some publications have focused on the nature of absorptive capacity in practice and the role of social interaction in enhancing it. Recent literature on absorptive capacity calls for studies that shed light on the relationship between individual absorptive capacity and organisational absorptive capacity. There has also been a call to examine absorptive capacity in non-research and development environments. Drawing on the literature on employee-driven innovation and social capital, this thesis looks at how individual observations and ideas are converted into something that an organisation can use. The critical phases of absorptive capacity, during which the ideas of individuals are incorporated into a group context, are assimilation and transformation. These two phases are seen as complementary: whereas assimilation is the application of easy-to-accept knowledge, transformation challenges the current way of thinking. The two require distinct kinds of social interaction and practices. The results of this study can been crystallised thus: “Enhancing absorptive capacity in practicebased non-research and development context is to organise the optimal circumstances for social interaction. Every individual is a potential source of signals leading to innovations. The individual, thus, recognises opportunities and acquires signals. Through the social interaction processes of assimilation and transformation, these signals are processed into the organisation’s reality and language. The conditions of creative social capital facilitate the interplay between assimilation and transformation. An organisation that strives for employee-driven innovation gains the benefits of a broader surface for opportunity recognition and faster absorption.” If organisations and managers become more aware of the benefits of enhancing absorptive capacity in practice, they have reason to assign resources to those practices that facilitate the creation of absorptive capacity. By recognising the underlying social mechanisms and structural features that lead either to assimilation or transformation, it is easier to balance between renewal and effective operations.

Effect of age of a sorghum-sudangrass hybrid on its allelopathic action

Hybrids of Sorghum sudanensis (sudangrass) and Sorghum bicolor genotypes can produce high amounts of biomass, sorgoleone (a long chain hydroquinone), and other phytotoxic substances. Shoots and roots of a sorghum-sudangrass hybrid (cv. Trudan 8) were collected 10, 20, 30, 40, and 50 days after emergence. Four concentrations of aqueous extracts from the shoots and roots (0, 0.4, 2, and 10 g L-1, w/v) were used to treat seeds of lettuce (Lactuca sativa), tomato (Lycopersicum sculentum), purslane (Portulaca oleracea), and pigweed (Amaranthus retroflexus). Seed germination of lettuce, tomato, and pigweed was inhibited by extracts from sorghum-sudangrass shoots at 10 g L-1 when made from sorghum-sudangrass plants 20 days or less in age. Seed germination of purslane was not inhibited by any sorghum-sudangrass extract. Growth of the four species evaluated were systematically inhibited when treated with 10 g L-1 extracts from sorghum-sudangrass shoots harvested up to 10 days after emergence.

Toxic action of aqueous wheat straw extract on horse e purslane

The toxic action of aqueous wheat (Triticum aestivum) straw extracts was investigated on germination, early seedling growth, some biochemical attributes and the antioxidant enzymes of horse purslane (Trianthemaportulacastrum). Aqueous extracts of wheat straw were prepared by soaking the wheat straw in distilled water in 1:10 w/v ratio and diluted to obtain the concentrations of 0, 25, 50, 75 and 100%. These were used as pre and post emergence in laboratory and screen house trials. Wheat aqueous extracts exhibited phytotoxicity to horse purslane by inhibiting and delaying its germination and suppressing seedling growth. Wheat phytotoxins in its aqueous extracts suppressed the chlorophyll content and soluble protein, and enhanced soluble phenolics and the activity of antioxidant enzymes as catalase, peroxidase and superoxide dismutase in the seedlings of horse purslane compared with the control. Such inhibitory activity is believed to originate from exposure to wheat phytotoxins that are present in its aqueous straw extract. The suppressive effects of wheat straw need to be investigated further under field conditions.

The many faces of strikes : attitudes towards industrial action by labour, management and human resources

Strikes provide a current, fresh but also a seldom-addressed issue to study from economic sciences perspective. This study provides to filling this research gap by trying to identify attitudes towards strikes that can be found inside organizations. The research problem this study then sets out to answer is: “What kinds of attitudes exist inside organizations towards industrial actions and how attitudes vary between labour, management and human resources?” This study has been planned with a view to test how qualitative attitudinal research, as a method, is suited to studying a phenomenon such as strike. At the heart of this research approach lies an assumption linked to rhetoric social psychology, that attitude is a phenomenon that can be identified in argumentation. For this research 10 semi-structured interviews in 4 organizations were conducted utilizing statements and pictures as stimulants for discussion. The material was transcribed and analysed following the two levels, categorical and interpretive, demanded by the chosen method. Altogether five attitudes were discovered; three of them negative, one indifferent and one positive by nature. The negative attitudes of unfairness, failure and personification towards strikes represented the side of strikes that was perhaps the most anticipated, portraying the contradictions between employees and employer. The attitude of ordinariness, which portrayed indifference, and the positive attitude of change however, were more unanticipated findings. They reflect shared understanding and trust between conflict parties. The utilization of qualitative attitudinal approach to study strikes was deemed successful. The results of this study support prior literature on workplace conflicts for example in regards of the definition of conflict and typologies conflicts. In addition the multifaceted nature of strikes can be perceived as one statement supported by this study. It arises in the nature of the attitudes, the diversity of discussion themes during the interviews as well as in the extent of possible theories to apply.

Mefenpyr-diethyl action on fenoxaprop-p-ethyl detoxification in wheat varieties

Safeners protect crops against herbicide injury. The aim of this study was to examine the differential susceptibility of five wheat (Triticum aestivum) varieties to the herbicide fenoxaprop-p-ethyl, as well as the performance of mefenpyr-diethyl on minimizing herbicide injury and on lipid contents. Varieties BRS 49, CD 104, CEP 24, IAPAR 78 and Rubi were sprayed with fenoxaprop-p-ethyl (69 g ha¹), fenoxaprop-p-ethyl + mefenpyr-diethyl (69 g + 18.75 g ha-1), or mefenpyr-diethyl (18.75 g ha-1). Plants were evaluated visually for injury at 7 and 14 days after treatment (DAT). Glutathione S-transferase (GST) activity was assayed in aerial parts at 7 DAT, and lipid content was measured at 14 DAT. Varieties CEP 24, IAPAR 78 and Rubi were more tolerant to fenoxaprop-p-ethyl than BRS 49, and CD 104 rapidly recovering from the slight phytotoxicity symptoms produced by the herbicide. Mefenpyr-diethyl prevented crop injury associated with the herbicide. GST activity did not correlate directly with fenoxaprop-p-ethyl detoxification. However, lipid content was related to the susceptibility of wheat to fenoxaprop-p-ethyl treatment.
