Economic Growth and Poverty: Does Formalisation of Informal Enterprises Matter?

The informal sector (IS) in developing countries plays significant roles viz., the provision of employment, incomes and supplying ignored markets. However, the working and employment conditions in the sector are still poor. Thus, its expansion and changing structures have drawn the attention of scholars and international policy makers on factors hindering its formalisation. Among the addressed factors include high costs of formalisation and lack of incentives to operate in the formal sector. To overcome these factors, various approaches have been adopted by different stakeholders. The paper assesses these approaches, factors related to informality-formality trade-off and the question of formalisation as a solution for firms’ growth. Looking at the problems faced by informal enterprises and the literature addressing options to accelerate the formalisation of informal enterprises, the paper briefly summarises the weaknesses of these approaches.informal sector; small enterprises; formal and informal institutions; informality; poverty; economic growth

Economic Growth and Poverty: Does Formalisation of Informal Enterprises Matter?

The informal sector (IS) plays a significant role in developing countries viz. the provision of employment, income and supplying ignored markets. However, working and employment conditions within the sector are still poor. Its expansion and changing structures have thus drawn the attention of scholars and international policy makers to the factors hindering its formalisation. Among the factors addressed are the high costs of formalisation and the lack of incentives for operating in the formal sector. A variety of approaches have been adopted by different stakeholders to overcome these factors. This paper assesses these approaches along with the factors related to informality-formality trade-off and the issue of formalisation as a solution for firms’ growth. By focussing on the problems faced by informal enterprises and the literature which addresses the options for accelerating the formalisation of informal enterprises, the paper will briefly summarise the weaknesses of these approaches.Informal sector, small enterprises, formal and informal institution, cost of formalisation, informality, formality, poverty, economic growth

Graph attribution through sub-graphs

We offer an alternative to the standard formalisation of attributed graphs. We propose to represent an attributed graph as a graph with a marked sub-graph, in which the sub-graph represents the data domain, rather than as a tuple of graph and algebra. This is a general construction which can be shown to preserve adhesiveness of categories; it has the advantage of uniformity and gives more flexibility in defining data abstractions. We show equivalence of our formalisation with the standard one, under a suitable encoding of algebras as graphs

Institutionalising Ontology-Based Semantic Integration

We address what is still a scarcity of general mathematical foundations for ontology-based semantic integration underlying current knowledge engineering methodologies in decentralised and distributed environments. After recalling the first-order ontology-based approach to semantic integration and a formalisation of ontological commitment, we propose a general theory that uses a syntax-and interpretation-independent formulation of language, ontology, and ontological commitment in terms of institutions. We claim that our formalisation generalises the intuitive notion of ontology-based semantic integration while retaining its basic insight, and we apply it for eliciting and hence comparing various increasingly complex notions of semantic integration and ontological commitment based on differing understandings of semantics

Variables, Generality and Existence: considerations on the notion of a concept-script

A defense of the Frege / Russell idea of logic as a 'concept=script' or 'ideal language', and a discussion of the relationship of this project to the formalisation of mass nouns or non-count noun

Heckscher-Ohlin in Theory and Reality

Most economists think that H-O works well in theory, but badly in reality, whereas the opposite is closer to the truth. After a long decline, H-O has recently experienced an empirical revival, but the standard Samuelsonian formalisation of the theory is still unsatisfactory. A modified formalisation of the theory, which gives trade costs more of a role, fits the evidence better. Appropriately interpreted, H-O is a useful part of the theory of economic development, as well as of international trade.

Integrating R&D and marketing in new product development

R&D - marketing integration is considered to be a critical activity within New Product Development (NPD). A theoretical framework for the study of R&D - marketing integration levels developed by Gupta et al (1986) is one of the most widely cited R&D - marketing integration frameworks in scientific literature. It is based on the presumption that strategy, environmental, organizational and individual factors are those determining R&D - marketing integration levels and consequently NPD success. Several empirical studies have been conducted to test this framework, however most of them have dealt only with portions of Gupta et al (1986)'s model. This paper is an attempt to put forward and test an integrated research protocol for the study of R&D - marketing integration, based on this theoretical framework. Empirical evidence gained from a questionnaire survey and two company case studies show, that people active within the R&D - marketing interface perceive the studied constructs as relevant for R&D - marketing integration, thus giving confirmation to Gupta et al (1986)’s model. The presented research protocol can therefore be considered as a valid start into R&D - marketing integration research within an integrated framework

Two-phased knowledge formalisation for hydrometallurgical gold ore process recommendation and validation

This paper describes an approach to externalising and formalising expert knowledge involved in the design and evaluation of hydrometallurgical process chains for gold ore treatment. The objective was to create a case-based reasoning application for recommending and validating a treatment process of gold ores. We describe a twofold approach. Formalising human expert knowledge about gold mining situations enables the retrieval of similar mining contexts and respective process chains, based on prospection data gathered from a potential gold mining site. Secondly, empirical knowledge on hydrometallurgical treatments is formalised. This enabled us to evaluate and, where needed, redesign the process chain that was recommended by the first aspect of our approach. The main problems with formalisation of knowledge in the domain of gold ore refinement are the diversity and the amount of parameters used in literature and by experts to describe a mining context. We demonstrate how similarity knowledge was used to formalise literature knowledge. The evaluation of data gathered from experiments with an initial prototype workflow recommender, Auric Adviser, provides promising results
