The impact of career capital on expatriates’ perceived marketability

We examine how the development of three types of career capital (knowing how, knowing whom, and knowing why) during an international assignment affects the perceived marketability of organizational expatriates. Using the perceived marketability perspective and long-term follow-up data, we show that knowing how is seen as the most transferable type of career capital, while the development of other aspects of career capital has little impact on perceived marketability. We also show that career capital development is more recognized in the external market than by current employers. Our findings expand our understanding of long-term career marketability among people who have completed international assignments.

Why do adaptable people feel less insecure? Indirect effects of career adaptability on job and career insecurity via two types of perceived marketability

The aim of the present study was to analyze if and how career adaptability reduces different types of insecurity. More specifically, we argue in a theoretical model at the intersection of career and organizational research that perceived internal and external marketability serve as connecting variables in the link between career adaptability and job and career insecurity. We tested our assumptions by means of multiple indirect effects path analyses across two measurement points (6 month timespan) with data from 142 university researchers working in the STEM fields. The results showed that career adaptability was positively related to perceived internal and external marketability, which both subsequently were negatively associated with job and career insecurity. We draw theoretical implications for career research in intra- and extraorganizational settings and discuss practical implications for fostering secure employment.

Polyhydroxyalkanoates production by photosynthetic mixed cultures

Polyhydroxyalkanoates (PHAs) are natural biologically synthesized polymers that have been the subject of much interest in the last decades due to their biodegradability. Thus far, its microbial production is associated with high operational costs, which increases PHA prices and limits its marketability. To address this situation, this thesis’ work proposes the utilization of photosynthetic mixed cultures (PMC) as a new PHA production system that may lead to a reduction in operational costs. In fact, the operational strategies developed in this work led to the selection of PHA accumulating PMCs that, unlike the traditional mixed microbial cultures, do not require aeration, thus permitting savings in this significant operational cost. In particular, the first PHA accumulating PMC tested in this work was selected under non-aerated illuminated conditions in a feast and famine regime, being obtained a consortium of bacteria and algae, where photosynthetic bacteria accumulated PHA during the feast phase and consumed it for growth during the famine phase, using the oxygen produced by algae. In this symbiotic system, a maximum PHA content of 20% cell dry weight (cdw) was reached, proving for the first time, the capacity of a PMC to accumulate PHA. During adaptation to dark/light alternating conditions, the culture decreased its algae content but maintained its viability, achieving a PHA content of 30% cdw. Also, the PMC was found to be able to utilize different volatile fatty acids for PHA production, accumulating up to 20% cdw of a PHA co-polymer composed of 3-hydroxybutyrate (3HB) and 3-hydroxyvalerate (HV) monomers. Finally, a new selective approach for the enrichment of PMCs in PHA accumulating bacteria was tested. Instead of imposing a feast and famine regime, a permanent feast regime was used, thus selecting a PMC that was capable of simultaneously growing and accumulating PHA, being attained a maximum PHA content of 60% cdw, the highest value reported for a PMC thus far. The results presented in this thesis prospect the utilization of cheap, VFA-rich fermented wastes as substrates for PHA production, which combined with this new photosynthetic technology opens up the possibility for direct sunlight illumination, leading to a more cost-effective and environmentally sustainable PHA production process.

Postharvest changes and respiratory pattern of bacuri fruit (Platonia insignis Mart.) at different maturity stages during ambient storage

Bacuri (Platonia insignis, Mart.) is one of the most important among Amazonian fruits. However, little is known about its postharvest physiology, such as maturity stages, changes during ambient storage, and respiratory pattern. Fruits were harvested at three maturity stages based on epicarp colour: dark green, light green, and turning (50% yellow), in order to determine colour modification and respiratory pattern during ambient storage (25.2 ºC, 75.1 % RH). Fruit of all maturity stages showed, after three days of harvest, a non-climacteric respiratory pattern, with turning fruit presenting the highest CO2 production rate until the fourth storage day (177.63 mg.CO2.kg-1.h-1). Yellowing increased throughout storage as related to lightness, chromaticity, and hue angle reductions. Turning fruit can be stored at ambient conditions for up to 10 days without any loss in marketability.

Trypanorhynch Cestodes of Commercial Fishes from Northeast Brazilian Coastal Waters

A large scale investigation on trypanorhynch cestode infestation of tropical marine fishes was carried out along the Northeast Brazilian coast in the summer of 1991 and 1993. A total of 798 fish specimens belonging to 57 species and 30 families were examined. Metacestodes of 11 different trypanorhynchs were found: Callitetrarhynchus gracilis, Dasyrhynchus giganteus, Grillotia sp., Nybelinia edwinlintoni, N. indica, N. senegalensis, Nybelinia c.f. lingualis, Otobothrium cysticum, Pseudolacistorhynchus noodti, Pseudotobothrium dipsacum and Pterobothrium kingstoni. Scanning electron microscopy was used to clarify details of the tentacular armature of some species. Rose-thorn shaped hooklets, regularly arranged like microtriches, are described from the bothridial surface of N. edwinlintoni. Of the 57 fish species, 15 harboured trypanorhynch cestodes. Of these the mullid Pseudupeneus maculatus was the most heavily infested fish species, harbouring 5 different trypanorhynch species. P. noodti in P. maculatus had the highest prevalence (87%) and intensity (maximum = 63) of infestation. C. gracilis was the parasite with the lowest host-specificity. It could be isolated from 10 fish species. The cestode fauna of the Northeast Brazilian coast appears to be similar to that of the West African coast. Five of the trypanorhynch cestodes found during this study are common to both localities. The two single cases of intra musculature infestation in Citharichthys spilopterus and Haemulon aurolineatum by trypanorhynch cestodes indicate that marketability of the investigated commercially exploited fish species is inconsequential.

Postharvest UV-B treatments increased fructose content of tomato (Solanum lycopersicon L. cv. Tayfun F1) harvested at different ripening stages

Abstract In the postharvest stage, taste and flavor are the key components of the marketability of tomato. Therefore, greater emphasis is now being placed on improving traits such as sugar content. In this study postharvest ultraviolet-B (UV-B) treatments on sugar, total soluble solids, and color of tomatoes harvested at different stages were investigated. Tomatoes harvested at turning, pink, and red stages were treated with two different doses of UV-B irradiation: UVB4 and UVB8. Color L* and hue angle values of tomatoes treated with UV-B were found to be high, which means the red color of tomatoes was improved. UVB4 treatments increased the color a* and saturation index values of tomatoes at pink and red harvest stage, although it did not affect at the turning stage. Additionally, UV-B irradiation treatments had no effect on sucrose content of the tomatoes. Fructose, glucose, and TSS content of tomatoes treated with UVB8 at red harvest stage were found to be high. Hence, the results obtained from this study are of great importance in terms of providing an increase in the amount of sugar without the need for breeding, and also consumer satisfaction.

Les déterminants du succès subjectif de carrière : possibilités de mobilité externe et congruence personne-organisation

Le succès de carrière a fait l’objet d’une multitude d’études et deux formes de succès ont été identifiées; le succès subjectif et le succès objectif de carrière. Dans le cadre de notre recherche, nous nous sommes intéressés au succès subjectif de carrière compte tenu de son association confirmée avec le bien-être psychologique, la qualité de la vie au travail (Nabi, 2003; Peluchette, 1993), la motivation intrinsèque, la confiance en soi (Abele et Spurk, 2009b) et l’engagement envers l’organisation (Hennequin, 2009a). En outre, selon diverses études (Arthur, Khapova et Wilderom, 2005; El Akremi, Guerrero et Neveu, 2006), le succès de carrière a tendance à être examiné plus sur la base des critères objectifs (salaire et promotions) que des critères subjectifs (la perception de l’individu). Par ailleurs, il y a eu une méta-analyse, élaborée par Ng, Eby, Sorensen et Feldman (2005) qui a examiné les déterminants du succès de carrière, à la lumière de deux perspectives théoriques développées par Turner (1960); soit la perspective de la mobilité par concours « contest mobility » et la perspective de la mobilité sponsorisée « sponsored mobility ». Ces auteurs ont révélé que les recherches sur le succès de carrière ont une portée limitée; « there is only a limited range of variables being examined as predictor of career success » (p. 396); d’où la nécessité d’examiner d’autres déterminants de succès de carrière, en les associant aux deux perspectives théoriques développées par Turner (1960). La présente recherche s’inscrit également dans la lignée des études qui ont pour but d’analyser les déterminants du succès de carrière. Toutefois, elle traite des liens entre le succès subjectif de carrière, les possibilités de mobilité externe et la congruence personne-organisation. Sur la base des recommandations de Ng, Eby, Sorensen et Feldman (2005), nous avons associé la congruence personne-organisation au modèle de la mobilité sponsorisé et les possibilités de mobilité externe au modèle de la mobilité par concours. Notre étude est de type explicatif, compte tenu du fait qu’elle tente de vérifier les liens entre le succès subjectif de carrière, les possibilités de mobilité externe et la congruence personne-organisation. À cet effet, nous avons eu recours à des données qui ont été colligées auprès de professionnels des ressources humaines, membre de l’ordre des conseillers en ressources humaines et en relations industrielles (Saba et Dufour, 2005) afin de pouvoir tester empiriquement les liens que nous anticipions entre notre variable dépendante (succès subjectif de carrière) et nos variables indépendantes (congruence personne-organisation et possibilités de mobilité externe) en tenant compte à la fois de notre variable médiatrice, à savoir le sponsorat organisationnel qui intervient dans le lien entre la congruence personne-organisation, et de nos variables de contrôle, qui sont l’âge, le genre, le statut marital, la scolarité, l'ancienneté dans l'organisation et l'ancienneté sur le marché du travail. Par ailleurs, nous avons adopté une méthode quantitative et nous avons procédé à des analyses statistiques, afin de faire sortir les caractéristiques de la distribution des variables; à des analyses bivariées, afin d’analyser les relations (statistiques) entre notre variable dépendante (succès subjectif de carrière) et chacune de nos variables indépendantes (la congruence personne-organisation et les possibilités de mobilité externe) et à une régression multiple, afin de déterminer si des corrélations existent entre les différentes variables à l’étude, nous avons également effectué un test de médiation afin de vérifier le rôle médiateur du sponsorat organisationnel dans le lien entre la congruence personne-organisation et le succès subjectif de carrière. De façon générale, nos hypothèses de recherche on été confirmées. Les possibilités de mobilité externe et la congruence personne-organisation sont liées positivement au succès subjectif de carrière. De plus, nous avons identifié une médiation partielle du sponsorat organisationnel dans le lien entre la congruence personne-organisation et le succès subjectif de carrière.

Applying 3D modelling technology to traditional craftwork : rapid prototyping in artisanal jewellery making and its impact on the perceived value of jewellery

Depuis la révolution industrielle, l’évolution de la technologie bouleverse le monde de la fabrication. Aujourd'hui, de nouvelles technologies telles que le prototypage rapide font une percée dans des domaines comme celui de la fabrication de bijoux, appartenant jadis à l'artisanat et en bouscule les traditions par l'introduction de méthodes plus rapides et plus faciles. Cette recherche vise à répondre aux deux questions suivantes : - ‘En quoi le prototypage rapide influence-t-il la pratique de fabrication de bijoux?’ - ‘En quoi influence-t-il de potentiels acheteurs dans leur appréciation du bijou?’ L' approche consiste en une collecte de données faite au cours de trois entretiens avec différents bijoutiers et une rencontre de deux groupes de discussion composés de consommateurs potentiels. Les résultats ont révélé l’utilité du prototypage rapide pour surmonter un certain nombre d'obstacles inhérents au fait-main, tel que dans sa géométrie, sa commercialisation, et sa finesse de détails. Cependant, il se crée une distance entre la main du bijoutier et l'objet, changeant ainsi la nature de la pratique. Cette technologie est perçue comme un moyen moins authentique car la machine rappelle la production de masse et la possibilité de reproduction en série détruit la notion d’unicité du bijou, en réduisant ainsi sa charge émotionnelle. Cette recherche propose une meilleure compréhension de l'utilisation du prototypage rapide et de ses conséquences dans la fabrication de bijoux. Peut-être ouvrira-t-elle la voie à une recherche visant un meilleur mariage entre cette technique et les méthodes traditionnelles.

Packaging materials for shrimp, fish and fish products, their properties, selection and effect of different packaging materials on their shelf life

Packaging is important not only in extending the shellife of fish and fishery products but also improving their marketability. In the recent years, significant development have taken place in the packaging industry. During the past decade in India, there is almost a packaging revolution with the availability of variety packaging materials, thus generating better packaging consciousness in other producer/manufacturing industries. But unfortunately, such realisation is not forthcoming in the fisheries sector and packaging techniques for local and export trade continues to be on traditional lines with their inherent drawbacks and limitations. Better packaging ensures improved quality and presentation of the products and ensures higher returns to the producer. Among several packaging materials used in fishery industry, ISI specifications had been formulated only for corrugated fibre board boxes for export of seafoods and froglegs. This standard was formulated before containersiation came into existance in the export of marine products. Before containerisation, the standards were stringent in view of the rough handling, transportation and storage. Two of the common defects reported in the master cartons exported from India are low mechanical strength and tendency to get wet. They are weakened by the deposits of moisture caused by temperature fluctuations during loading, unloading and other handling stages. It is necessary to rectify the above defects in packaging aquatic products and hence in the present study extensive investigations are carried out to find out the reasons for the damage of master cartons, to evolve code of practice for the packaging oi frozen shrimp for exports, development of alternative style of packaging for the shipping container, development of suitable consumer packaging materials for fish soup powder, cured dried mackeral, fish pickles in oil and frozen shrimp. For the development of suitable packaging materials, it is absolutely essential to know the properties of packaging materials, effect of different packaging materials on theirshelf life and their suitability for food contact applications.

Wild food trees in Eastern Nuba Mountains, Sudan: Use diversity and threatening factors

This study was conducted in 2010 in Eastern Nuba Mountains, Sudan to investigate ethnobotanical food and non-food uses of 16 wild edible fruit producing trees. Quantitative and qualitative information was collected from 105 individuals distributed in 7 villages using a semi-structured questionnaire. Also gathering of data was done using a number of rapid rural appraisal techniques, including key informant interviews, group discussion, secondary data sources and direct observations. Data was analysed using fidelity level and informant consensus factor methods to reveal the cultural importance of species and use category. Utilizations for timber products were found of most community importance than food usages, especially during cultivated food abundance. Balanites aegyptiaca, Ziziphus spina-christi and Tamarindus indica fruits were asserted as most preferable over the others and of high marketability in most of the study sites. Harvesting for timber-based utilizations in addition to agricultural expansion and overgrazing were the principal threats to wild edible food producing trees in the area. The on and off prevailing armed conflict in the area make it crucial to conserve wild food trees which usually play a more significant role in securing food supply during emergency times, especially in times of famine and wars. Increasing the awareness of population on importance of wild food trees and securing alternative income sources, other than wood products, is necessary in any rural development programme aiming at securing food and sustaining its resources in the area.

Economic impact of Turnip mosaic virus, Cauliflower mosaic virus and Beet mosaic virus in three Kenyan vegetables

Screenhouse experiments conducted in Kenya showed that inoculation of cabbage seedlings with Turnip mosaic virus (TuMV), either alone, or in combination with Cauliflower mosaic virus (CaMV), reduced the number and weight of marketable harvested heads. When viruses were inoculated simultaneously, 25% of cabbage heads were non-marketable, representing 20-fold loss compared with control. By contrast, inoculation with CaMV alone had insignificant effects on cabbage yield. This suggests that TuMV is the more detrimental of these pathogens, and its management should be a priority. Early exposure to TuMV produced cabbages that were 50% lighter than non-infected plants, but later infection was less damaging suggesting that controlling virus infection at the seedling stage is more important. TuMV was far less damaging to kale than it was to cabbage; although high proportions of TuMV-inoculated kale plants showed symptoms (> 90%), the marketability and quality of leaves were not significantly reduced, and no clear relationship existed between timing of infection and subsequent crop losses. Early inoculation of Swiss chard with Beet mosaic virus (BtMV) significantly impaired leaf quality (similar to 50% reduction in marketable leaf production), but the impact of disease was greatest in plants that had been inoculated at maturity, where average leaf losses were two and a half times those recorded in virus-free plants. Disease-management of BtMV in Swiss chard is important, therefore, not only at the seedling stage, but particularly when plants are transplanted from nursery to field.

Regulation and innovation: Rethinking 'inclusive' housing design

The Lifetime Homes (LTH) concept initiated in 1989 by the Helen Hamlyn Trust, and subsequently promoted by the Joseph Rowntree Foundation, emerged at a point when there was growing awareness of the decline of both private and public sector housing quality, especially in relation to floorspace standards (Karn & Sheridan, 1994). LTH were intended to offset the concerns of first, the house buying public of the appearance and affordability of homes suitable for successive generations, second, the private house building industry of the cost and marketability of incorporating 'inclusive' design features, and third, Registered Social Landlords (RSLs), who had to balance cost constraints with addressing the needs of a growing number of households with older and/or disabled people. Approved Document Part M of the building regulations was extended in 1999, from public buildings to private dwellings, and currently requires that all new housing meet minimal 'visitability' criteria. Indeed, although the signs are that Part M will be incrementally extended to comprise LTH principles, the paper argues that in their existing form they are insufficient to act as a key component of the government's 'new agenda for British housing'. This paper therefore explores how they might usefully be expanded from an approach, largely based on compromise, to one that inspires innovative, flexible and inclusive house forms, which also challenge design conventions.

Decision theory and real estate development: a note on uncertainty

Real estate development appraisal is a quantification of future expectations. The appraisal model relies upon the valuer/developer having an understanding of the future in terms of the future marketability of the completed development and the future cost of development. In some cases the developer has some degree of control over the possible variation in the variables, as with the cost of construction through the choice of specification. However, other variables, such as the sale price of the final product, are totally dependent upon the vagaries of the market at the completion date. To try to address the risk of a different outcome to the one expected (modelled) the developer will often carry out a sensitivity analysis on the development. However, traditional sensitivity analysis has generally only looked at the best and worst scenarios and has focused on the anticipated or expected outcomes. This does not take into account uncertainty and the range of outcomes that can happen. A fuller analysis should include examination of the uncertainties in each of the components of the appraisal and account for the appropriate distributions of the variables. Similarly, as many of the variables in the model are not independent, the variables need to be correlated. This requires a standardised approach and we suggest that the use of a generic forecasting software package, in this case Crystal Ball, allows the analyst to work with an existing development appraisal model set up in Excel (or other spreadsheet) and to work with a predetermined set of probability distributions. Without a full knowledge of risk, developers are unable to determine the anticipated level of return that should be sought to compensate for the risk. This model allows the user a better understanding of the possible outcomes for the development. Ultimately the final decision will be made relative to current expectations and current business constraints, but by assessing the upside and downside risks more appropriately, the decision maker should be better placed to make a more informed and “better”.
