Life Cycle Development

In developing countries, the role of women in the business sector is continuously improving. As a result, female enterprises have also been encouraged in Pakistan. This study is based on life cycle development phases from which women-owned enterprises have to go through in order to become successful. As a primary data source, face-to-face interviews with owners of successful women-owned enterprises were preferred. The data collection process was divided into two phases i.e. Phase-I and Phase-II. After data collection, qualitative analysis has been performed using NVIVO. Findings provide both generic and specific factors involved in life cycle development of women-owned enterprises. This study provides a detailed view of life cycle development model followed by successful women enterprises. The outcome of this research work is a theoretical finding which can be utilized by entrepreneurs owning small scale enterprises to improve their level of performance. Findings can also be helpful for potentially talented women interested in setting up their own business.

The life cycle of the sugarcane smut fungus Sporisorium scitamineum is a multistep process. Haploid sporidia of compatible (MAT-1 versus MAT-2) mating types fuse to generate pathogenic dikaryotic hyphae to infect the host. Within the host tissues, diploid teliospores are formed and induce a characteristic sorus that looks like a black whip. The diploid teliospores germinate to form haploid sporidia by meiosis. In order to monitor fungal development throughout the whole life cycle, we expressed the green fluorescent protein (GFP) and red fluorescent protein (RFP) in S. scitamineum MAT-1 and MAT-2 sporidia, respectively. Observation by epifluorescence microscope showed that conjugation tube formation and sporidia fusion occurred at 4 to 8 h, and formation of dikaryotic filaments was detected at 12 h after mating. The resultant teliospores, with diffused GFP and RFP, underwent meiosis as demonstrated by septated hypha with single fluorescent signal. We demonstrated that GFP- and RFP-tagged strains can be used to study the life cycle development of the fungal pathogen S. scitamineum, including the sexual mating and meiosis events. This dual-color imaging system would be a valuable tool for investigation of biotic and abiotic factors that might affect the fungal life cycle development and pathogenesis.

The paper presents the results of studies of the seven-spotted beetle ( Coccinella septempunctata L.) life cycle, which has 2 generations in the climatic zone of southern Russia. The main stages of the life cycle are the emergence of imago from winter diapause, the first generation from egg to imago, the second generation from egg to imago, the care of adults for wintering. The eating behavior of coccinellid was studied at each stage of the life cycle, which showed the presence of a small herbivorous period (phytophagous beetles), most of the cycle of the beetles had a predatory lifestyle (entomophage beetles). Experiments in the natural and artificial conditions of studying the nutrition of a seven-point beetle showed that adult beetles were more effective in consuming aphids than the larvae. It was also established that in the natural environment, the degree of palatability, both in the larva and in the imago, was directly dependent on the density of the aphids: as the aphid decreased, the feeding intensity of the beetles decreased. To increase the efficiency of aphid consumption, the joint content of two predatory beetles in the imago stage was used: a seven-spotted beetle ( Coccinella septempunctata L.) and ground beetle ( Tomocarabus bessarabicus concretus Fischer von Waldheim). With such simultaneous use (polyculture), a synergistic effect was observed in their consumption of rosan aphid ( Macrosiphum rosae L.).

This chapter deals with the planning aspects of an IDCM project, including scope, feasibility, and life-cycle development. It reviews the typical project deliverables that may be used during planning and subsequent phases. The objectives are to consider and discuss: • The importance of planning to the successful implementation of an IDCM solution, and the need to distinguish between product development and project life-cycles; • A product development life-cycle that enterprises can use for an IDCM project; • The steps involved in initiating and defining an IDCM project; • An approach to aligning the development of a management framework with requirements for enabling an IDCM solution, including a review of key life-cycle stages; • Development of a project organization structure that may be applicable for an enterprise IDCM project; • Identification of a set of risks to form the basis of a Risk Management Plan; and • Methodologies suitable for an IDCM project.
