Developing a service model for a successful freight forwarding organisation in South Africa

The Freight Logistics Industry underpins the efficient movement of freight goods globally and supports the South African economy by accounting for 80% of the movement of goods. While South Africa’s formal trade with the rest of the continent and the world has increased steadily over the years, the country is yet to make significant inroads in some of its larger and fast-growing economies. This is despite having a substantially more diversified economic base and relatively higher levels of technological advance-ment (Department of Research and Information, 2018). Complex challenges relating to transport infrastructure (roads, customs processes, sea- and airports, amongst others), determine the efficiency with which business can be done and therefore has a direct impact on the growth of the Freight Logistics Pro-vider (FLP) industry (Belfreight, 2016). Changes in the global business environment have also led FLP’s to diversity strate-gies, incorporating asset ownership on a small to large scale in order to cope with the ever-changing demands of customers. However, at its core, the FLP industry exists to manage the freight transport process. This study investigated, through interviews and surveys involving senior industry pro-fessionals; whether a service model for a successful FLP could be developed; one that did not require asset ownership. The empirical evidence gathered yielded a list of the top FLP services currently being used in business; together with the support structures and enablers for these services in the form of transport modes. A model was then developed based on these param-eters that would best suit a small to medium sized FLP for success. Success in this study proved to be non-tangible due to the limited information available in company and industry figures, however, indication of an optimal market by product was included in the developed model

Strategies for internet route control: past, present and future

Uno de los problemas más complejos en redes de computadores es el de proporcionar garantías de calidad y confiabilidad a las comunicaciones de datos entre entidades que se encuentran en dominios distintos. Esto se debe a un amplio conjunto de razones -- las cuales serán analizadas en detalle en esta tesis -- pero de manera muy breve podemos destacar: i) la limitada flexibilidad que presenta el modelo actual de encaminamiento inter-dominio en materia de ingeniería de tráfico; ii) la naturaleza distribuida y potencialmente antagónica de las políticas de encaminamiento, las cuales son administradas individualmente y sin coordinación por cada dominio en Internet; y iii) las carencias del protocolo de encaminamiento inter-dominio utilizado en Internet, denominado BGP (Border Gateway Protocol).El objetivo de esta tesis, es precisamente el estudio y propuesta de soluciones que permitan mejorar drásticamente la calidad y confiabilidad de las comunicaciones de datos en redes conformadas por múltiples dominios.Una de las principales herramientas para lograr este fin, es tomar el control de las decisiones de encaminamiento y las posibles acciones de ingeniería de tráfico llevadas a cabo en cada dominio. Por este motivo, esta tesis explora distintas estrategias de como controlar en forma precisa y eficiente, tanto el encaminamiento como las decisiones de ingeniería de tráfico en Internet. En la actualidad este control reside principalmente en BGP, el cual como indicamos anteriormente, es uno de los principales responsables de las limitantes existentes. El paso natural sería reemplazar a BGP, pero su despliegue actual y su reconocida operatividad en muchos otros aspectos, resultan claros indicadores de que su sustitución (ó su posible evolución) será probablemente gradual. En este escenario, esta tesis propone analizar y contribuir con nuevas estrategias en materia de control de encaminamiento e ingeniería de tráfico inter-dominio en tres marcos temporales distintos: i) en la actualidad en redes IP; ii) en un futuro cercano en redes IP/MPLS (MultiProtocol Label Switching); y iii) a largo plazo en redes ópticas, modelando así una evolución progresiva y realista, facilitando el reemplazo gradual de BGP.Más concretamente, este trabajo analiza y contribuye mediante: - La propuesta de estrategias incrementales basadas en el Control Inteligente de Rutas (Intelligent Route Control, IRC) para redes IP en la actualidad. Las estrategias propuestas en este caso son de carácter incremental en el sentido de que interaccionan con BGP, solucionando varias de las carencias que éste presenta sin llegar a proponer aún su reemplazo. - La propuesta de estrategias concurrentes basadas en extender el concepto del PCE (Path Computation Element) proveniente del IETF (Internet Engineering Task Force) para redes IP/MPLS en un futuro cercano. Las estrategias propuestas en este caso son de carácter concurrente en el sentido de que no interaccionan con BGP y pueden ser desplegadas en forma paralela. En este caso, BGP continúa controlando el encaminamiento y las acciones de ingeniería de tráfico inter-dominio del tráfico IP, pero el control del tráfico IP/MPLS se efectúa en forma independiente de BGP mediante los PCEs.- La propuesta de estrategias que reemplazan completamente a BGP basadas en la incorporación de un nuevo agente de control, al cual denominamos IDRA (Inter-Domain Routing Agent). Estos agentes proporcionan un plano de control dedicado, físicamente independiente del plano de datos, y con gran capacidad computacional para las futuras redes ópticas multi-dominio.Los resultados expuestos aquí validan la efectividad de las estrategias propuestas, las cuales mejoran significativamente tanto la concepción como la performance de las actuales soluciones en el área de Control Inteligente de Rutas, del esperado PCE en un futuro cercano, y de las propuestas existentes para extender BGP al área de redes ópticas.One of the most complex problems in computer networks is how to provide guaranteed performance and reliability to the communications carried out between nodes located in different domains. This is due to several reasons -- which will be analyzed in detail in this thesis -- but in brief, this is mostly due to: i) the limited capabilities of the current inter-domain routing model in terms of Traffic Engineering (TE); ii) the distributed and potentially conflicting nature of policy-based routing, where routing policies are managed independently and without coordination among domains; and iii) the clear limitations of the inter-domain routing protocol, namely, the Border Gateway Protocol (BGP). The goal of this thesis is precisely to study and propose solutions allowing to drastically improve the performance and reliability of inter-domain communications. One of the most important tools to achieve this goal, is to control the routing and TE decisions performed by routing domains. Therefore, this thesis explores different strategies on how to control such decisions in a highly efficient and accurate way. At present, this control mostly resides in BGP, but as mentioned above, BGP is in fact one of the main causes of the existing limitations. The natural next-step would be to replace BGP, but the large installed base at present together with its recognized effectiveness in other aspects, are clear indicators that its replacement (or its possible evolution) will probably be gradually put into practice.In this framework, this thesis proposes to to study and contribute with novel strategies to control the routing and TE decisions of domains in three different time frames: i) at present in IP multi-domain networks; ii) in the near-future in IP/MPLS (MultiProtocol Label Switching) multi- domain networks; and iii) in the future optical Internet, modeling in this way a realistic and progressive evolution, facilitating the gradual replacement of BGP.More specifically, the contributions in this thesis can be summarized as follows. - We start by proposing incremental strategies based on Intelligent Route Control (IRC) solutions for IP networks. The strategies proposed in this case are incremental in the sense that they interact with BGP, and tackle several of its well-known limitations. - Then, we propose a set of concurrent route control strategies for MPLS networks, based on broadening the concept of the Path Computation Element (PCE) coming from the IETF (Internet Engineering Task Force). Our strategies are concurrent in the sense that they do not interact directly with BGP, and they can be deployed in parallel. In this case, BGP still controlls the routing and TE actions concerning regular IP-based traffic, but not how IP/MPLS paths are routed and controlled. These are handled independently by the PCEs.- We end with the proposal of a set of route control strategies for multi-domain optical networks, where BGP has been completely replaced. These strategies are supported by the introduction of a new route control element, which we named Inter-Domain Routing Agent (IDRA). These IDRAs provide a dedicated control plane, i.e., physically independent from the data plane, and with high computational capacity for future optical networks.The results obtained validate the effectiveness of the strategies proposed here, and confirm that our proposals significantly improve both the conception and performance of the current IRC solutions, the expected PCE in the near-future, as well as the existing proposals about the optical extension of BGP.Postprint (published version

Resource orchestration strategies with retrials for latency-sensitive network slicing over distributed telco clouds

The new radio technologies (i.e. 5G and beyond) will allow a new generation of innovative services operated by vertical industries (e.g. robotic cloud, autonomous vehicles, etc.) with more stringent QoS requirements, especially in terms of end-to-end latency. Other technological changes, such as Network Function Virtualization (NFV) and Software-Defined Networking (SDN), will bring unique service capabilities to networks by enabling flexible network slicing that can be tailored to the needs of vertical services. However, effective orchestration strategies need to be put in place to offer latency minimization while also maximizing resource utilization for telco providers to address vertical requirements and increase their revenue. Looking at this objective, this paper addresses a latency-sensitive orchestration problem by proposing different strategies for the coordinated selection of virtual resources (network, computational, and storage resources) in distributed DCs while meeting vertical requirements (e.g., bandwidth demand) for network slicing. Three orchestration strategies are presented to minimize latency or the blocking probability through effective resource utilization. To further reduce the slice request blocking, orchestration strategies also encompass a retrial mechanism applied to rejected slice requests. Regarding latency, two components were considered, namely processing and network latency. An extensive set of simulations was carried out over a wide and composite telco cloud infrastructure in which different types of data centers coexist characterized by a different network location, size, and processing capacity. The results compare the behavior of the strategies in addressing latency minimization and service request fulfillment, also considering the impact of the retrial mechanism.This work was supported in part by the Department of Excellence in Robotics and Artificial Intelligence by Ministero dell’Istruzione, dell’Università e della Ricerca (MIUR) to Scuola Superiore Sant’Anna, and in part by the Project 5GROWTH under Agreement 856709

Arab management accounting systems under the influence of their culture

Due to globalization, business opportunities can be established in new countries more than ever before. The Arab countries are gaining more attention as emerging markets in global business. Applying managerial accounting on a global basis requires an understanding of the cultural aspects of the countries. Arabic culture has a long history on the one hand and contradicts the Western cultures sharply on the other hand. Research on comparative management accounting (CMA) emerged in the early 1990s. Recently, research on transitional economies is focusing on management accounting practice in these emerging markets, but only a small proportion of this research deal with some aspects of Arab management accounting and control systems. Thus, the relative lack of attention paid to Arab culture in relation to management accounting is quite significant. The research explores the characteristics of management accounting systems in the Arab World. Thus, this research explores the role of management accounting in Arab companies in decision-making, strategic planning, control, and performance measurement. In addition, this research examines the impact of Arab culture on their MASs specifically. Furthermore, the Anglo-American countries have a particular importance and significant influences on the Arab World. Hence, this research compares some aspects of Arab MASs with Anglo-American MASs. A qualitative field study is an essential part of the research methodology in order to identify the scope of management accounting and generate evidence from the field. The data will be gathered primarily through open-ended, face-to-face interviews from three different Arab countries. In addition, an in-depth case study is conducted on a Sharia-compliant company, which represents a special kind of Arab companies. Furthermore, the cross-sectional data analyses are based on different dimensions derived from the theoretical framework. The results reveal that the finance department in Arab companies carries out financial and managerial accounting tasks. Arab companies can be also characterized by short-term budgeting. In addition, Arab companies use traditional instruments in management accounting and performance evaluation. The empirical results show the limited role of management accounting in Arab companies, especially in terms of strategic decisions. The findings affirm that culture is an ultimate factor influencing Arab MASs. Furthermore, the findings indicate that Arab management accounting practice is influenced by the Anglo-American MA knowledge and institutions. The study also points to the importance of organizational culture on MASs in Arab companies. Importing international knowledge and improving the education and training in field of MA will help Arab companies in developing their MASs

INVESTORS’ RIGHTS, TRANSPARENCY AND INFORMATION IN EQUITY BASED ISLAMIC FINANCE: AN EXPLORATION INTO ISLAMIC PRIVATE EQUITY IN THE GCC

Islamic principles encourage the use of risk-sharing modes of financing and private equity is one of the organizational formats that uses these instruments. However, there has been no in-depth study on Islamic private equity (IPE) that examines the issues arising in implementing equity-based financing. IPE involves an investment where Islamic Financial Institutions (IFIs) and investors are bound together by a contractual relationship that is greatly influenced by trust. Private equity relationships involve investments in different projects and ventures on a risk-sharing basis with not much known, especially about the post-investment period. Furthermore, private equity is considered to be one-sided agreements since there is no room to negotiate pre-investment, little or no voting power post-investment, a process to resolve conflict of interest matters is lacking and accounting is off the balance sheet. All of the above gives rise to a potential conflict of interest and makes the availability of market information essential to the investors. Thus, enhancing the transparency and flow of information can be the strategic factor in developing the Islamic private equity market (IPE). Moreover, in IPE investors depend highly on the Shari’ah Supervisory Board (SSB) supervision and oversight for ensuring Shari’ah compliance, yet the independence of SSB is questioned. Given the above, the aim of the study is to explore the relationship between the investors and IFI investing in IPE across the GCC, reflecting on investors’ rights and compliance with the principles and goals of Shari’ah. The study followed an inductive approach, using athe mixed model, combining qualitative and quantitative data collection and analysis techniques. Participants: investors (Islamic and conventional), IFIs and Shari’ah scholars, were selected using sampling and judgmental techniques. The results were analysed using descriptive and inferential statistical methods. The findings indicate that transparency and investor communication is lacking and IFIs need to improve on the disclosure mechanism towards their investors. The governance of the investment structure and of the IFI management, the ability to negotiate, and the independence of Shari’ah supervision and review are some of the key issues that would need to be addressed/strengthened to enhance the investors’ confidence. Regulations are to be navigated towards enhancing transparency, publicity and accountability. The desire is not only for regulations on the availability of information, but also to ensure they are enforced and consequences may result from non-compliance. In addition, in introducing an independent set-up, SSB independence can be enhanced. Furthermore, with the concept of IPE investment being a contractual agreement, an effective supervision, contract enforcement and legal system is required

The application of social media for marketing strategies in pharma healthcare

Digital is transforming the way the world does business, and healthcare is no exception. The COVID-19 outbreak has had a significant impact on internet use and accelerated the digital transition worldwide as well as in Portugal. Social media is the fastest communication network among worldwide people. During the outbreak, the usage of social media platforms increased two times more compared with normal days. With increasing health literacy and access to technology, consumers are becoming more informed and proactive towards health issues and selfmedication, 67% of them are researching health problems and symptoms tracking and 81% conduct online research before making a purchase. This change has expanded communication from offline to the internet. Electronic word-of-mouth communication (eWOM), based on social media, brought more variables to marketing communication and became an interesting field for research considering its communication potential. Indeed, several studies have shown the ability to influence interpersonal communications on products or services in the purchase intention of consumers. As so, in recent years, some authors discussed the impact of eWOM on consumer online purchasing decisions; however, the literature is still relatively nascent regarding the Pharmaceutical Industry and the self-medication segment market of Over-the-Counter medicines (OTC). Pharmaceutical companies must be aware of this paradigm change: the patient is an indispensable and active stakeholder in the present and future of healthcare, besides the physician and the payer. Pharma marketing may be moving into a more digitalized space, but there is still room for improvement, especially when it comes to social media there is an unexploited territory for pharma marketers as most pharmaceutical companies are not yet to answer these consumers habits with an effective digital presence. The current research aims to study the application of Social Media platforms for marketing or communication purposes in pharma healthcare in Portugal.digital está a transformar a forma como os negócios se fazem no mundo, e a saúde não é exceção. A pandemia de COVID-19 teve um impacto significativo na utilização da Internet e acelerou a transição digital a nível mundial, incluindo Portugal. Com o aumento da literacia em saúde e o acesso à tecnologia, os consumidores estão a tornar-se mais informados e proativos em relação aos seus cuidados com a saúde e à automedicação, 67% destes pesquisam problemas de saúde e sintomas e 81% realizam pesquisas online antes de fazer uma compra. Esta mudança de comportamento expandiu a comunicação do offline para a Internet. A comunicação electronic word-of-mouth (eWOM), baseada nos media sociais, envolve mais variáveis para a comunicação de marketing; nos últimos anos, alguns autores discutiram o impacto do eWOM nas decisões de compra do consumidor online; entretanto, a literatura ainda é relativamente incipiente no que diz respeito à Indústria Farmacêutica e ao segmento de automedicação do mercado de medicamentos de venda livre (OTC). As empresas farmacêuticas devem estar atentas a esta mudança de paradigma: o paciente é uma parte indispensável e ativa no presente e no futuro da área da saúde, além do médico e do pagador. O marketing farmacêutico está a evoluir para a digitalização, mas ainda há espaço para melhorias, especialmente no âmbito das redes sociais que ainda são um território pouco explorado pelos profissionais de marketing farmacêutico. A maioria das empresas farmacêuticas ainda não se adaptou a estes hábitos de consumo com uma presença digital eficaz. A presente investigação pretende identificar a aplicação de plataformas de redes sociais para efeitos de marketing ou comunicação na área da indústria farmacêutica em Portugal
