Age-dependence of cultured pearl grade and colour in the black-lipped pearl oyster Pinctada margaritifera

Pinctada margaritifera is an economically important marine bivalve species for cultured pearl production in French Polynesian aquaculture. In order to evaluate the influence of donor oyster age on pearl quality traits, experiments were conducted over 6 years using both grafts and surgreffe operations. At harvest, 6 pearl quality traits were recorded and compared: surface defects, luster, grade, darkness level, and visual color. Analyzing the quality traits of pearls harvested in the initial graft process and those of pearls obtained from surgreffe experiments allowed a comparison of the influence of pearl sac cells originating from the initial mantle graft, which aged together with their recipient oysters. The results demonstrated a significant decrease between these successive grafts in luster, grade (A-B-C,) darkness level, and green color – traits that are of major importance in the pearl market. The duplicated graft experiment allowed the comparison of donor oyster families at 2 and 5 years old, where a mantle graft was inserted into recipient oysters aged 2.5 years old. The results showed the same tendencies to a lesser extent, with 1) an improved pearl grade, predominantly through a most important rate of 0 surface defect category, and 2) a green / grey ratio in favor of the younger donor. A comparison between the graft-surgreffe and the duplicated graft experiments also highlighted: 1) the indirect role played by the younger recipient oysters, which must be optimized for optimal pearl quality realization, and 2) the complex interplay between donor and recipient oysters.

The symbolic, socio-economic and exchange value of Imperial German and National Socialist medals and badges, 1701 to the present

This thesis examines the manufacture, use, exchange (including gift exchange), collecting and commodification of German medals and badges from the early 18th century until the present-day, with particular attention being given to the symbols that were deployed by the National Socialist German Workers’ Party (NSDAP) between 1919 and 1945. It does so by focusing in particular on the construction of value through insignia, and how such badges and their symbolic and monetary value changed over time. In order to achieve this, the thesis adopts a chronological structure, which encompasses the creation of Prussia in 1701, the Napoleonic wars and the increased democratisation of military awards such as the Iron Cross during the Great War. The collapse of the Kaiserreich in 1918 was the major factor that led to the creation of the NSDAP under the eventual strangle-hold of Hitler, a fundamentally racist and anti-Semitic movement that continued the German tradition of awarding and wearing badges. The traditional symbols of Imperial Germany, such as the eagle, were then infused with the swastika, an emblem that was meant to signify anti-Semitism, thus creating a hybrid identity. This combination was then replicated en-masse, and eventually eclipsed all the symbols that had possessed symbolic significance in Germany’s past. After Hitler was appointed Chancellor in 1933, millions of medals and badges were produced in an effort to create a racially based “People’s Community”, but the steel and iron that were required for munitions eventually led to substitute materials being utilised and developed in order to manufacture millions of politically oriented badges. The Second World War unleashed Nazi terror across Europe, and the conscripts and volunteers who took part in this fight for living-space were rewarded with medals that were modelled on those that had been instituted during Imperial times. The colonial conquest and occupation of the East by the Wehrmacht, the Order Police and the Waffen-SS surpassed the brutality of former wars that finally culminated in the Holocaust, and some of these horrific crimes and the perpetrators of them were perversely rewarded with medals and badges. Despite Nazism being thoroughly discredited, many of the Allied soldiers who occupied Germany took part in the age-old practice of obtaining trophies of war, which reconfigured the meaning of Nazi badges as souvenirs, and began the process of their increased commodification on an emerging secondary collectors’ market. In order to analyse the dynamics of this market, a “basket” of badges is examined that enables a discussion of the role that aesthetics, scarcity and authenticity have in determining the price of the artefacts. In summary, this thesis demonstrates how the symbolic, socio-economic and exchange value of German military and political medals and badges has changed substantially over time, provides a stimulus for scholars to conduct research in this under-developed area, and encourages collectors to investigate the artefacts that they collect in a more historically contextualised manner.

Estimating market access in non-GPA countries: A suggested methodology

The WTO’s Agreement on Government Procurement (GPA) has data reporting obligations for all its Contracting Parties. Submitting such data promotes transparency in public procurement and also signals tendencies towards discrimination. However, most developing countries, especially emerging economies, are non-members of the GPA and therefore have no comparable data reporting obligations. In most cases, this has led to an absence of any reliable data on these countries’ public purchases, which poses a serious challenge in international negotiations on the subject and in examining the impact of protectionist measures in these countries’ public markets. In this short paper, we attempt to overcome these data challenges by developing a methodology to estimate the size of procurement markets in non-GPA countries as well as foreign market access therein. We also show the results from this methodology for estimating the EU’s access in select emerging economies’ public markets.

Services Procurement under the WTO’s Agreement on Government Procurement: Whither Market Access?

This paper studies the government procurement of services from foreign suppliers by conducting a statistical analysis of data submitted by Japan and Switzerland to the WTO's Committee on Government Procurement. Using several metrics, the paper examines if the WTO’s Agreement on Government Procurement (GPA) has led to greater market access for foreign suppliers in services procurement. Our results indicate that despite the GPA, the proportions of services contracts awarded to foreigners have declined over time for both countries and in the absence of this decline, the value of services contracts awarded to foreign firms would have been more than 15 times higher in the case of Japan and nearly 68 times more in the case of Switzerland. We also find that for the same services categories, at least the Japanese government is not purchasing as much from abroad as it's private sector is importing from the rest of the world, a finding that further points to the home-bias in that government's public purchase decisions.

How to address the ethics of reproductive travel to developing countries: a comparison of national self-sufficiency and regulated market approaches

One of the areas of concern raised by cross-border reproductive travelregards the treatment of women who are solicited to provide their ova orsurrogacy services to foreign consumers. This is particularly troublesome inthe context of developing countries where endemic poverty and low standardsfor both medical care and informed consent may place these womenat risk of exploitation and harm. We explore two contrasting proposals forpolicy development regarding the industry, both of which seek to promoteethical outcomes and social justice: While one proposal advocates efforts tominimize cross-border demand for female reproductive resources throughthe pursuit of national self-sufficiency, the other defends cross-border tradeas a means for meeting the needs of vulnerable groups. Despite theconflicting objectives of the proposed strategies, the paper identifiescommon values and points of agreement between the two, including theimportance of regulations to safeguard those providing ova or surrogacyservices.

Value chain supply procurement strategies in international construction: cases of foreign constructors in China

Purpose – Firms compete using a variety of strategies. Typically they aim to provide something different, to be better, or simply cheaper. In the construction industry, the performance characteristics, quality and cost of the final delivered project will be the outcome of the interplay of capabilities of all the firms involved in the project. Consequently, in order to improve competitiveness, firms must pay attention to not only their own competitive advantage but to those of the firms, both up-stream and down-stream, on whom they depend in delivering their projects. For foreign constructors in China, those competitive considerations will be informed by circumstances different from home. How then do foreign constructors adapt themselves to the problem of sourcing competitively when located within a China-based supply chain? The paper aims to discuss these issues.

Design/methodology/approach – In this study 60 foreign enterprises operating within the Chinese construction sector were investigated by using a comparative case study approach.

Findings – Four generic procurement strategies were identified. First, firms adapt themselves in the search for optimal supply sources by replicating home-based suppliers, controlling local suppliers, or by remaining agile and non-aligned. Second, firms develop niche supply monopolies through market dominance, uniquely differentiated offerings, or by integration with down-stream providers. Third, firms find opportunities to bring in off-shore technology intensive procurements, where that technology is either protected, improved upon, or sold. Finally, firms also seek to transit to China as a procurement base in order to reduce local supply cost, service world-wide operations, or as part of a total strategy of China relocation.

Originality/value – The identification of this rich range of procurement approaches will be of interest to internationalization strategists, as well as to industry practitioners looking to find appropriate business models for off-shore operations.

Foreign-born CEOs, Country-Specific Skills, Selection, and Strategic Consequences

In this dissertation, I first suggest an extension of the managerial rents model and more specifically the managerial skills typology that it offers. Building on research in international business, I propose adding country-specific skills (CSS) to this typology in addition to firm-specific, industry-specific, and generic skills. I define CSS as managers’ abilities that are applicable and specific to a particular national institutional context. Such skills are distinct from the other three types identified and are likely to influence managers’ performance and the performance of their firms. So if CSS are distinct skills, what are the implications for strategy and international business research? In an attempt to respond to this question, I conduct two empirical essays in which I examine the implications of this refinement of the typology of managerial skills for CEO selection and firms’ mergers and acquisitions (M&A) strategy. In the first empirical essay, I puzzle at the fact that although CSS constitute a barrier to high-level executive mobility across countries, there have been a growing number of foreign-born CEOs being appointed across the globe. Why are these individuals being selected for the post of CEO? Using information on the appointment of foreign-born and national CEOs from 2005 to 2010 among global 500 companies, I show that internationalization pressures help explain their selection and that two types of firms are likely to appoint foreign leaders: highly internationalized firms and firms that are likely to internationalize. In the second empirical essay, I examine the strategic implications of country-specific skills. Employing the same sample as the one used in the first empirical essay, I demonstrate that given that their mindset is likely to be less focused on firms’ home market, foreign-born CEOs may be prone to institute more changes in firms’ cross-border M&A strategy than their domestic counterparts. I also theorize on the moderating influence of CEOs’ insiderness.

Three Essays on Market Depth in Futures Markets

Liquidity is an important market characteristic for participants in every financial market. One of the three components of liquidity is market depth. Prior literature lacks a comprehensive analysis of depth in U.S. futures markets due to past limitations on the availability of data. However, recent innovations in data collection and dissemination provide new opportunities to investigate the depth dimension of liquidity. In this dissertation, the Chicago Mercantile Exchange (CME) Group proprietary database on depth is employed to study the dynamics of depth in the U.S. futures markets. This database allows for the analysis of depth along the entire limit order book rather than just at the first level. The first essay examines the characteristics of depth within the context of the five-deep limit order book. Results show that a large amount of depth is present in the book beyond the best level. Furthermore, the findings show that the characteristics of five-deep depth between day and night trading vary and that depth is unequal across levels within the limit order book. The second essay examines the link between the five-deep market depth and the bid-ask spread. The results suggest an inverse relation between the spread and the depth after adjusting for control factors. The third essay explores transitory volatility in relation to depth in the limit order book. Evidence supports the relation between an increase in volatility and a subsequent decrease in market depth. Overall, the results of this dissertation are consistent with limit order traders actively managing depth along the limit order book in electronic U.S. futures markets.

The Spanish equity market (2000-2014): stylized facts

Introduction. This thesis is framed in the last 15 years of history of the Spanish equity market (years 2000 to 2014). In this sense and, as an introduction of this work, in the first chapter the main features of the background of the electronic market for shares and the implications that the migration from out-c1y circles to this automatic system is explained. The main changes of this electronic system (Spanish stock exchange interconnection system) are detailed in this part. Also in this first chapter is explained the important European meeting, in December 1999, of eight stock exchanges which foresee, in a first step, to design a single market model for, lately, try to merge, final step that did not take place. After this initial moment in December 1999, in this work the main features of the market model of the main European markets (London, Paris, Germany and Italy) are generally described, given that it is important to consider the European context of the Spanish equity market, specially during these last fifteen years. Along chapter two, the thesis is supported with the theoretic frame explaining here the nature of markets and their important role in the economy, detailing afte1wards the Spanish case from the point of view of its institutional structure and legal framework. Besides, in this chapter, a deep review of initial public offerings (main concepts and calendar steps) is done as well as take-over bids (typology and key-concepts)...

Effects of trunk-shaker harvester and ethephon on plant water status, leaf gas exchange, and yield of citrus cultivated under Mediterranean conditions

This work was aimed to study whether the application of ethephon as an abscission agent and mechanical harvest using a trunk shaker have any effect on plant water status, leaf gas exchange, and yield of mandarin and orange trees cultivated under Mediterranean conditions. The experiment was performed from 2008 to 2011 in five commercial orchards where parameters related to the plant water status and leaf gas exchange were measured before the application of ethephon, at harvest time and at different occasions after harvest. In addition, the effects of ethephon dose on yield in the current and subsequent seasons were also evaluated. Results showed that ethephon applications and mechanical harvest did not detrimentally affect plant water status in any of the cultivars studied. Furthermore, either had no effect or had a short temporal decrease effect on leaf gas exchange depending on the cultivar studied although with no consequences for the fruit yield obtained during the current season. Increasing ethephon doses led to fruit yield reductions in the mandarin ‘Orogrande’ trees in subsequent seasons. When trunk-shaker and ethephon applications were combined, however, yields from the late-maturing orange significantly decline in subsequent seasons. Overall, results show that using a trunk shaker is a viable technique to mechanically harvest citrus trees destined to both fresh and industry market and can be considered as an alternative to the traditional manual harvest usually performed under Mediterranean conditions. However, its use cannot be recommended for late-maturing oranges, such as the ‘Navel Lane Late’ in which mature fruit and fruitlets coexist in the tree at the time of harvest.

The significant role of third-party logistics (3pl) operators as fosterers of organizational performance in colombian companies

La eliminación de barreras entre países es una consecuencia que llega con la globalización y con los acuerdos de TLC firmados en los últimos años. Esto implica un crecimiento significativo del comercio exterior, lo cual se ve reflejado en un aumento de la complejidad de la cadena de suministro de las empresas. Debido a lo anterior, se hace necesaria la búsqueda de alternativas para obtener altos niveles de productividad y competitividad dentro de las empresas en Colombia, ya que el entorno se ha vuelto cada vez más complejo, saturado de competencia no sólo nacional, sino también internacional. Para mantenerse en una posición competitiva favorable, las compañías deben enfocarse en las actividades que le agregan valor a su negocio, por lo cual una de las alternativas que se están adoptando hoy en día es la tercerización de funciones logísticas a empresas especializadas en el manejo de estos servicios. Tales empresas son los Proveedores de servicios logísticos (LSP), quienes actúan como agentes externos a la organización al gestionar, controlar y proporcionar actividades logísticas en nombre de un contratante. Las actividades realizadas pueden incluir todas o parte de las actividades logísticas, pero como mínimo la gestión y ejecución del transporte y almacenamiento deben estar incluidos (Berglund, 2000). El propósito del documento es analizar el papel de los Operadores Logísticos de Tercer nivel (3PL) como promotores del desempeño organizacional en las empresas colombianas, con el fin de informar a las MIPYMES acerca de los beneficios que se obtienen al trabajar con LSP como un medio para mejorar la posición competitiva del país.

El rol de la Unión Africana (UA) en el Cuerno de África a partir del caso de Somalia - AMISOM (2007-2013)

El propósito de esta monografía es comprender cuál ha sido el rol de la Unión Africana (UA), dentro de la misión de paz AMISOM en el periodo de 2007- 2013. Por ello, el trabajo abarca aspectos geopolíticos e históricos, que han influido en la configuración del conflicto armado de Somalía y que han llevado progresivamente a la creación, evolución e implementación de mecanismos como las misiones de paz. Además, se abarcan los planteamientos del neo-funcionalismo y el neo-regionalismo para comprender las estructuras y las dinámicas propias de la UA y así, comprender la naturaleza tanto de sus acciones, como de sus propósitos; propósitos que aclaman el fomento del panafricanismo. Desde aquí se puede entender como su rol ha contribuido con el crecimiento del mercado de la industria militar en la región, a costa de la responsabilidad de proteger. Por último, se concluye que dichas dinámicas han llevado a la creación de comunidades de inseguridad.

Estudio del tratado de libre comercio Colombia – Estados Unidos: Iowa, Kansas, Kentucky, Luisiana y Maine

Con el proceso de globalización que se evidencia actualmente, el comercio entre países ha sido uno de los factores más relevantes a través del tiempo y Colombia no ha sido excluyente a esta situación. Es por la importancia del asunto, que la Escuela de Administración dentro de sus múltiples proyectos de investigación busca la identificación de oportunidades para PYMES colombianas en mercados extranjeros, específicamente en Estados Unidos, asumiendo los retos que trae consigo un Tratado de Libre Comercio, las implicaciones en cuanto a los procesos de intercambio (importaciones y exportaciones) en sus diversos ámbitos y el impacto que genera dicho proceso en la balanza comercial colombiana. Debido a esto, se ha propuesto el desarrollo de un trabajo de grado que analice el Tratado de Libre Comercio (TLC) entre Colombia y Estados Unidos, enfocándose en los perfiles de cada mercado y las necesidades de los mismos, con el fin de identificar oportunidades generadas desde su puesta en marcha. En busca de un análisis detallado, el trabajo en mención hace énfasis en cinco estados de Estados Unidos (Iowa, Kansas, Kentucky, Luisiana y Maine) y los 32 departamentos de Colombia. Con el objetivo de realizar un análisis más efectivo se tomaron en cuenta las características de cada mercado y su relación comercial. A partir del previo proceso de investigación, se pretende identificar y definir oportunidades comerciales que evidencian una evolución comercial (mayor número de importaciones y exportaciones). Dichas oportunidades identificadas son el resultado de un análisis cualitativo tras desarrollar matrices de los principales diez productos más demandados por los Estados mencionados y los principales productos ofertados por los departamentos colombianos. Gracias a lo que enmarca un TLC dentro de un proceso de negociación, se proyecta identificar según las necesidades de las partes, es decir, oferta y demanda de bienes y/o 9 servicios, cada una de las oportunidades claves para los comerciantes nacionales que se involucran dentro del acuerdo aprobado.
