ERP implementation for an administrative agency as a corporative frontend and an e-commerce smartphone app

This document contains all the descriptions, arguments and demonstrations of the researches, analysis, reasoning, designs and tasks performed to achieve the requirement to technologically evolve an managing agency in a way that, through a solution that requires a reduced investment, makes possible to arrange a business management tool with e-commerce and also a mobile application that allows access and consultation of mentioned tool. The first part of the document describes the scenario in order to contextualize the project and introduces ERP (Enterprise Resources Planning). In the second part, a deep research of ERP market products is carried out, identifying the strengths and weaknesses of each one of the products in order to finish with the choice of the most suitable product for the scenario proposed in the project. A third part of the document describes the installation process of the selected product carried out based on the use of Dockers, as well as the configurations and customizations that they make on the selected ERP. A description of the installation and configuration of additional modules is also made, necessary to achieve the agreed scope of the project. In a fourth part of the thesis, the process of creating an iOS and Android App that connects to the selected ERP database is described. The process begins with the design of the App. Once designed, it is explained the process of study and documentation of technologies to choose the technology stack that allows making an application robust and contemporary without use of licensing. After choosing the technologies to use there are explained the dependencies and needs to install runtime enviornments prior to the start of coding. Later, it describes how the code of the App has been raised and developed. The compilation and verification mechanisms are indicated in continuation. And finally, it is showed the result of the development of the App once distributed. Finally, a chapter for the conclusions analyzes the difficulties encountered during the project and the achievements, analyzing what has been learned during the development of this project

Exploring heterogeneity of unreliable machines for p2p backup

P2P architecture is a viable option for enterprise backup. In contrast to dedicated backup servers, nowadays a standard solution, making backups directly on organization's workstations should be cheaper (as existing hardware is used), more efficient (as there is no single bottleneck server) and more reliable (as the machines are geographically dispersed). We present the architecture of a p2p backup system that uses pairwise replication contracts between a data owner and a replicator. In contrast to standard p2p storage systems using directly a DHT, the contracts allow our system to optimize replicas' placement depending on a specific optimization strategy, and so to take advantage of the heterogeneity of the machines and the network. Such optimization is particularly appealing in the context of backup: replicas can be geographically dispersed, the load sent over the network can be minimized, or the optimization goal can be to minimize the backup/restore time. However, managing the contracts, keeping them consistent and adjusting them in response to dynamically changing environment is challenging. We built a scientific prototype and ran the experiments on 150 workstations in the university's computer laboratories and, separately, on 50 PlanetLab nodes. We found out that the main factor affecting the quality of the system is the availability of the machines. Yet, our main conclusion is that it is possible to build an efficient and reliable backup system on highly unreliable machines (our computers had just 13% average availability)

Navigating overgrazing and cultural values through narratives and participatory mapping : a socio-cultural analysis of sheep grazing in the Faroe Islands

Long-term livestock grazing has shaped landscapes, biodiversity, societies, cultures, and economies in the North Atlantic over time. However, overgrazing has become a major environmental sustainability challenge for this region, covering the Faroe Islands, Greenland, Iceland, Norway, and Scotland. The objective of this study was to elicit narratives and spatial patterns of local people's management preferences for sheep grazing in the Faroe Islands through a socio-cultural lens. We collected data via a Public Participation Geographic Information Systems (PPGIS) survey with an open question about hopes and concerns for sheep management in the Faroe Islands and a mapping exercise for expressing spatial preferences for sheep management. Four distinct narratives emerged from a qualitative analysis of responses to the open question (n = 184): (1) Sustainable sheep management, (2) Nature without sheep, (3) Sheep as part of Faroese culture, and (4) Sheep as nuisance. Visual inspection of narrative-specific maps with locations where either no or fewer sheep were preferred indicated that sheep management is not simply a 'sheep vs. no sheep' issue but embedded in a more nuanced consideration of the place of sheep in the landscape and society. For example, for some residents sheep-farming is not a commercial enterprise but a social activity and local source of food. Our combined methodological approach using qualitative and spatial data can help researchers in other fields identify the interplay between place-specific areas of grazing management concern and socio-cultural values, enabling more targeted land-use management policies or plans.Peer reviewe

New venture internationalisation and the cluster life cycle: insights from Ireland’s indigenous software industry

The internationalization of new and small firms has been a long-standing concern of researchers in international business (Coviello and McAuley, 1999; Ruzzier et al., 2006). This topic has been re-invigorated over the last decade by the burgeoning literature on so-called ‘born globals’ (BG) or ‘international new ventures’ (INV) – businesses that confound the expectations of traditional theory by being active internationally at, or soon after, inception (Aspelund et al., 2007; Bell, 1995; Rialp et al., 2005). Until quite recently, this literature had not really considered how the home regional environment of a new venture might influence its internationalization behaviour. However, a handful of recent studies have shown that being founded in a geographic industry ‘cluster’ can positively influence the likelihood of a new venture internationalizing (e.g., Fernhaber et al., 2008; Libaers and Meyer, 2011). This chapter seeks to build on these recent contributions by further probing the relationship between clusters and new venture internationalization. Specifically, taking inspiration from recent work in the thematic research stream on clusters (which spans the fields of economic geography, regional studies and industrial dynamics), the chapter explores how the emergence and internationalization of new ventures might be affected by the ‘cluster life cycle’ context within which they are founded. This issue is examined through a revelatory longitudinal case study of Ireland’s indigenous software cluster. The study investigates the origins and internationalization behaviour of ‘leading’ Irish software ventures but, in contrast to many existing studies, it seeks to understand these firms within the context of the Irish software cluster’s emergence and evolution through a number of ‘life-cycle’ stages

Finding Australia’s social enterprise sector: final report

Executive Summary Social enterprises are organisations that: Are led by an economic, social, cultural, or environmental mission consistent with a public or community benefit; Trade to fulfil their mission; Derive a substantial portion of their income from trade; and Reinvest the majority of their profit/surplus in the fulfilment of their mission. This document reports on the research findings of the Finding Australia’s Social Enterprise Sector (FASES) project. FASES is a joint initiative of Social Traders and the Australian Centre for Philanthropy and Nonprofit Studies, Queensland University of Technology. It is a first attempt to identify the range and scope of social enterprises in Australia. The methodology utilised in this research included: a review of existing literature and methods of social enterprise mapping; establishment of a project website and preliminary discussion paper to stimulate public engagement with defining and identifying Australian social enterprises, which resulted in four online responses to the discussion paper and 157 nominations of social enterprises to be included in the research; a series of workshops and interviews with 34 key informants to assist in defining social enterprise for the purposes of the research; identification of the social enterprise population through a combination of web and media review, review of existing databases and feedback through the project website; development and administration of an online survey; and collation and analysis of secondary data. Five hundred and thirty-nine organisations commenced the online survey, of which 365 were valid social enterprises according to our definition. Based on pre-existing research data and information from our survey, we estimate that there are up to 20 000 Australian social enterprises. This estimate takes into account that some not for profit organisations have multiple business ventures, and that not all social enterprises are incorporated as not for profits. Our survey results suggest that the Australian social enterprise sector is mature, sustainable and internally diverse with regard to mission and organisational structure. Amongst the 365 survey respondents, 73% had been operational for at least five years, and 62% were at least 10 years old. Australian social enterprises seek to fulfil a diversity of missions and serve a wide variety of beneficiaries. As a whole, the dominant foci of our survey respondents were on creating opportunities for people to participate in their community, and on finding new solutions to social, environmental, cultural and economic problems. Australian social enterprises operate in every industry of our economy. Our survey data suggest that they trade predominantly in local and regional markets and focus on fulfilling their missions at local and regional goals. However, some social enterprises operate in international markets and seek to respond to missions of international scope
