Developing sustainable value proposition: A case study from manufacturing industry

Increasing pressures to reduce costs, inprove productivity, and lower the environmental impact are forcing suppliers to present evidences of the monetary and societal value they create for the customers and society around. The extant academic literature on the practical activities related to topic is still sparse and this study addresses the gap by developing sustainable customer value proposition for Valmet’s recycled fibre line solution for the Chinese market. The research is based on literature review and single case study method. Theoretically the study is connected to the emerging literature of customer value and life cycle engineering, and to the research of sustainable development in the field of marketing. For exloiting empirical evidences, in-depth supplier interviews and customer survey were conducted. The results suggest that selling of recycled fibre line solution requires tangible and credible evidence of the value and utility which is delivered for the customer. In addition to the economic benefits also societal benefits should be included in the value proposition that are the focus of attention in China. Still, the role of discovered benefits may be contradictory until they are communicated to appropriate decision makers. Managerially the study contributes to the customer value management and quantification knowledge and practices in Valmet’s organization.

Desenvolvimento reprodutivo de Hyptis suaveolens (L.) Poit.: relação entre fotoperíodo, densidade celular meristemática e padrão de expressão de um ortólogo putativo do gene LEAFY de arabidopsis

Hyptis suaveolens (L.) Poit. é uma planta da família Lamiaceae, considerada uma espécie tipicamente invasora. Entretanto, é produtora de óleo essencial, ao qual várias atividades biológicas são atribuídas. Informações sobre o desenvolvimento reprodutivo nesta espécie seriam úteis à elucidação de mecanismos adaptativos relacionados à indução floral em espécies invasoras, e ao incremento na produção de óleo essencial, devido sua preponderância nas flores. Assim, aqui caracterizamos alguns aspectos do desenvolvimento reprodutivo em Hyptis suaveolens. Plantas de H. suaveolens foram submetidas a dois tratamentos fotoperiódicos (fotoperíodo natural de Alfenas e fotoperíodo mínimo de 16 h) para amostragem de ápices aéreos vegetativos e florais em cinco datas. Nestes materiais botânicos foram realizadas análises anatômicas, ensaios de hibridização in situ para detecção dos transcritos de um ortólogo putativo de LEAFY e microscopia eletrônica de varredura. Hyptis suaveolens é uma planta de dias curtos, com fotoperíodo crítico em torno de 13 h. A atividade meristemática vegetativa ou floral pôde ser evidenciada pela densidade celular. O ortólogo putativo de LEAFY em H. suaveolens exibiu o padrão de expressão clássico descrito em Antirrhinum e Arabidopsis, mas também foi expresso em ápices vegetativos de plantas cultivadas sob fotoperíodo natural, independente da época de amostragem. Entretanto, não foi expresso em meristemas vegetativos de plantas cultivadas em fotoperíodo mínimo de 16 h. Estes resultados sugerem uma expressão basal de LEAFY em meristemas vegetativos de H. suaveolens, que é fortemente reduzida sob fotoperíodo mínimo de 16 h ou incrementada em fotoperíodos inferiores a 13 h, atingindo níveis satisfatórios à determinação floral.

Bridging the digital divide in developing countries: The role of mobile technology in bridging the digital divide

This thesis investigates how mobile technology usage could help to bring Information and communication technologies (ICT) to the people in developing countries. Some people in developing countries have access to use ICT while other people do not have such opportunity. This digital divide among people is present in many developing countries where computers and the Internet are difficult to access. The Internet provides information that can increase productivity and enable markets to function more efficiently. The Internet reduces information travel time and provides more efficient ways for firms and workers to operate. ICT and the Internet can provide opportunities for economic growth and productivity in developing countries. This indicates that it is very important to bridge the digital divide and increase Internet connections in developing countries. The purpose of this thesis is to investigate how can mobile technology and mobile services help to bridge the digital divide in developing countries. Theoretical background of this thesis consists of a collection of articles and reports. Theoretical material was gathered by going through literature on the digital divide, mobile technology and mobile application development. The empirical research was conducted by sending a questionnaire by email to a selection of application developers located in developing countries. The questionnaire’s purpose was to gather qualitative information concerning mobile application development in developing countries. This thesis main result suggests that mobile phones and mobile technology usage can help to bridge the digital divide in developing countries. This study finds that mobile technology provides one of the best tools that can help to bridge the digital divide in developing countries. Mobile technology can bring affordable ICT to people who do not have access to use computers. Smartphones can provide Internet connection, mobile services and mobile applications to a rapidly growing number of mobile phone users in developing countries. New low-cost smartphones empower people in developing countries to have access to information through the Internet. Mobile technology has the potential to help to bridge the digital divide in developing countries where a vast amount of people own mobile phones.

Xyloglucans from Hymenaea courbaril var. stilbocarpa seeds affect Arabidopsis thaliana seedling growth by enhancing lateral root development

The effect of crude xyloglucan (XG) preparations from jatobá (Hymenaea courbaril var. stilbocarpa (Hayne) Y. T. Lee & Langenh.) seeds on Arabidopsis thaliana (L.) Heynh. root system development was investigated. The XG extracts exerted a dual effect on root system development by slowing down root growth and improving lateral root formation. These observed morphological changes were not due to oligosaccharides that could be generated following hydrolysis of the XG polymers, since XG hydrolysate induced a drastic inhibition of the overall growth process of the Arabidopsis thaliana seedlings. Histochemical test of GUS gene expression assay performed on seven and 14-days-old transgenic Arabidopsis thaliana plants carrying the CycB1;1-GUS fusion indicated that the improvement of the lateral root development by jatobá XG extracts was not correlated with the expression of this cell cycle marker gene in the root system. A potential agricultural application of jatobá seeds XG extract is discussed.

Morphology and anatomy of the developing fruit of Maclura tinctoria, Moraceae

(Morphology and anatomy of the developing fruit of Maclura tinctoria, Moraceae). Maclura tinctoria (L.) D. Don ex Steudel was selected for the present study due of its economic and medicinal importance. The purpose of this investigation is to present a detailed description of the fruit development, specially by: (a) defining the fruit type presented by the species, and (b) characterizing the seed type of the species based upon the presence or not of mechanical tissue on the seed-coat. The fruit originates from the subglobose female inflorescence which consists of small unipistillate flowers with superior ovary, unilocular and uniovular apical placentation. The mature fruit is multiple, constituted of small drupes. The ovule is ana-campylotropous, suspended, bitegmic and crassinucellate. The mature seed is flattened, slightly ovated, cream colored, with unspecialized membrane coat with thin-walled cells more or less crushed. The seed has parenchymatic endosperm with lipophilic content. The embryo is straight, with two cotyledons of the same size. Ontogenetic studies reveal that the fruits are infrutescences. The fleshy edible part is derived from the perigone and inflorescence axis. The drupes consist of a single pyrene of macrosclereids.

Nuclear exclusion of transcription factors associated with apoptosis in developing nervous tissue

Programmed cell death in the form of apoptosis involves a network of metabolic events and may be triggered by a variety of stimuli in distinct cells. The nervous system contains several neuron and glial cell types, and developmental events are strongly dependent on selective cell interactions. Retinal explants have been used as a model to investigate apoptosis in nervous tissue. This preparation maintains the structural complexity and cell interactions similar to the retina in situ, and contains cells in all stages of development. We review the finding of nuclear exclusion of several transcription factors during apoptosis in retinal cells. The data reviewed in this paper suggest a link between apoptosis and a failure in the nucleo-cytoplasmic partition of transcription factors. It is argued that the nuclear exclusion of transcription factors may be an integral component of apoptosis both in the nervous system and in other types of cells and tissues.

Value Creation in Crowd-Business: Developing a Framework for Successful Implementation of Crowdsourcing Initiatives

By recent years the phenomenon called crowdsourcing has been acknowledged as an innovative form of value creation that must be taken seriously. Crowdsourcing can be defined as an act of outsourcing tasks originally performed inside an organization, or assigned externally in form of a business relationship, to an undefinably large, heterogeneous mass of potential actors. This thesis constructs a framework for successful implementation of crowdsourcing initiatives. Firms that rely entirely on their own research and ideas cannot compete with the innovative capacity that crowd-powered firms have. Nowadays, crowdsourcing has become one of the key capabilities of businesses due to its innovative capabilities, in addition to the existing internal resources of the firm. By utilizing crowdsourcing the business gains access to an enormous pool of competence and knowledge. However, various risks remain such as uncertainty of crowd structure and loss of internal know-how. Crowdsourcing Success Framework introduces a step by step model for implementing crowdsourcing into the everyday operations of the business. It starts from the decision to utilize crowdsourcing and continues further into planning, organizing and execution. Finally, this thesis presents the success factors of crowdsourcing initiative.

Pp2a: At The Crossroads Between Growth and Defence In Plants

Living organisms manage their resources in well evolutionary-preserved manner to grow and reproduce. Plants are no exceptions, beginning from their seed stage they have to perceive environmental conditions to avoid germination at wrong time or rough soil. Under favourable conditions, plants invest photosynthetic end products in cell and organ growth to provide best possible conditions for generation of offspring. Under natural conditions, however, plants are exposed to a multitude of environmental stress factors, including high light and insufficient light, drought and flooding, various bacteria and viruses, herbivores, and other plants that compete for nutrients and light. To survive under environmental challenges, plants have evolved signaling mechanisms that recognise environmental changes and perform fine-tuned actions that maintain cellular homeostasis. Controlled phosphorylation and dephosphorylation of proteins plays an important role in maintaining balanced flow of information within cells. In this study, I examined the role of protein phosphatase 2A (PP2A) on plant growth and acclimation under optimal and stressful conditions. To this aim, I studied gene expression profiles, proteomes and protein interactions, and their impacts on plant health and survival, taking advantage of the model plant Arabidopsis thaliana and the mutant approach. Special emphasis was made on two highly similar PP2A-B regulatory subunits, B’γ and B’ζ. Promoters of B’γ and B’ζ were found to be similarly active in the developing tissues of the plant. In mature leaves, however, the promoter of B’γ was active in patches in leaf periphery, while the activity of B’ζ promoter was evident in leaf edges. The partially overlapping expression patterns, together with computational models of B’γ and B’ζ within trimeric PP2A holoenzymes suggested that B’γ and B’ζ may competitively bind into similar PP2A trimmers and thus influence each other’s actions. Arabidopsis thaliana pp2a-b’γ and pp2a-b’γζ double mutants showed dwarfish phenotypes, indicating that B’γ and B’ζ are needed for appropriate growth regulation under favorable conditions. However, while pp2a-b’γ displayed constitutive immune responses and appearance of premature yellowings on leaves, the pp2a-b’γζ double mutant supressed these yellowings. More detailed analysis of defense responses revealed that B’γ and B’ζ mediate counteracting effects on salicylic acid dependent defense signalling. Associated with this, B’γ and B’ζ were both found to interact in vivo with CALCIUM DEPENDENT PROTEIN KINASE 1 (CPK1), a crucial element of salicylic acid signalling pathway against pathogens in plants. In addition, B’γ was shown to modulate cellular reactive oxygen species (ROS) metabolism by controlling the abundance of ALTERNATIVE OXIDASE 1A and 1D in mitochondria. PP2A B’γ and B’ζ subunits turned out to play crucial roles in the optimization of plant choices during their development. Taken together, PP2A allows fluent responses to environmental changes, maintenance of plant homeostasis, and grant survivability with minimised cost of redirection of resources from growth to defence.

Serum antigliadin antibody levels as a screening criterion before jejunal biopsy indication for celiac disease in a developing country

The objective of the present study was to determine the efficacy of detection of antigliadin immunoglobulins G and A (IgG and IgA) for the diagnosis of celiac disease in a developing country, since other enteropathies might alter the levels of these antibodies. Three groups were studied: 22 patients with celiac disease (mean age: 30.6 months), 61 patients with other enteropathies (mean age: 43.3 months), and 46 patients without enteropathies (mean age: 96.9 months). Antigliadin IgG and IgA ELISA showed sensitivity of 90.9 and 95.5%, respectively. With the hypothetical values of prevalence ranging from 1:500 to 1:2000 liveborns, the positive predictive value varied from 8.5 to 2.3% for IgG and from 4.8 to 1.1% for IgA. Considering the patients without enteropathies, specificity was 97.8 and 95.7% for IgG and IgA, respectively. In patients with other enteropathies, specificity was 82.0 and 84.1%, respectively. When patients with and without other enteropathies were considered as a whole, specificity was 88.8 and 91.6%, respectively. The specificity of positive IgG or IgA was 93.5% in children without enteropathies and 78.7% in the presence of other enteropathies. The negative predictive value for hypothetical prevalences varying from 1:500 to 1:2000 liveborns was 99.9%. Thus, even in developing countries where the prevalence of non-celiac enteropathies is high, the determination of serum antigliadin antibody levels is a useful screening test prior to the jejunal biopsy in the investigation of intestinal malabsorption.
