Abstract
The influence of variables such as temperature, agitation, oxygenation on the corrosion of aluminium, copper, nickel base alloys in 3% NaCI solution has been studied by electrochemical and weight loss measurements. It has been observed that the corrosion process is under cathodic control for all the alloys studied. Some nickel and aluminium base alloys merit consideration as a substitute for ferrous alloys in salt water under conditions similar to those reported in this paper.

Abstract
The identification, access, and acquisition of financial resources are critical to the growth of any entrepreneurial venture. To perform better, growth-oriented women entrepreneurs need financial resources. Unfortunately, obtaining financial resources is a greater obstacle for women entrepreneurs than for men entrepreneurs. This chapter considers three different options for growth financing: crowdfunding, angel financing, and venture capital. Suggested strategies for women entrepreneurs seeking to raise money are also offered.

The corrosion of Ti and Ti‐Hf25% alloy at 28°C (room temperature) in 20% MC1 and 20% H2SO4 solutions in the presence of 1g/litre of cations such as Fe+3, Cu+2, Ni+2 in each case…
Abstract
The corrosion of Ti and Ti‐Hf25% alloy at 28°C (room temperature) in 20% MC1 and 20% H2SO4 solutions in the presence of 1g/litre of cations such as Fe+3, Cu+2, Ni+2 in each case and of several organic inhibitors has been studied. Cationic additions of Fe+3 and Cu+2 to 20% H2SO4 inhibit much better than similar additions to 20% HC1 solution and generally exhibit higher inhibitor efficiencies than the organic inhibitors studied. The addtions of Fe+3 and Cu+2 to corroding media shift the electrode potentials to noble values. However Ni+2 additions are not found to be effective.

Abstract
New product development (NPD) project studies have attempted to identify a common set of factors that will indicate whether a NPD project will succeed or fail. A recent study has shown that there is no universal set of factors; also some factors have contradictory effects on a project’s success. A framework that classifies NPD projects into different contextual groups explains these anomalies. The grouping helps in determining the appropriate weights for the different success/failure factors, and the type of management organization and approach suitable for the project. The many subjective elements make classifying NPD projects into their appropriate contextual grouping difficult. Describes a rule‐based expert system which classifies NPD projects into their appropriate contextual groupings, suggests the level of emphasis for different success/failure factors and the right approach for managing.

Abstract
Ti and its alloys with Hf additions up to 50% (by weight) have been subjected to corrosion in organic acids and their mixtures, and 3% NaCl, 5% NaOH solutions under boiling conditions for their performance by weight change measurements. These alloys are found to be unaffected in boiling 3% NaCl and 5% NaOH solutions. Amongst titanium and Ti‐Hf alloys, Ti 50%‐Hf 50% behaves the best in the acids and their mixtures with the exception of HNO3. Correlation between polarisation characteristics and dissolution rates in boiling acids is seen only in 20% ortho H3PO4.

Abstract
The influence of such variables as temperature, agitation, oxygenation, etc., on the corrosion of aluminium bronze specimens with and without heat‐treatment in 3 and 24% NaCI solution has been studied by electrochemical methods and weight loss measurements. It has been observed that the corrosion process is under cathodic control under most of the experimental conditions. Properly heat‐treated specimens with beta‐phase present in preference to gamma2‐phase exhibit better corrosion‐resistance. Thus, with the improved corrosion‐resistance shown by suitably heat‐treated alloys the aluminium bronzes merit consideration as a substitute for other ferrous alloys for use in salt water.

Abstract
Women entrepreneurship is designated as the new engines of economic growth in developing countries. Prior research shows how men and women differ in starting a business, with women normally facing more restrictions on entrepreneurial financing, entrepreneurial growth, and entrepreneurial performance. This has often been explained by gender role, yet we still lack a systematic understanding of how gender roles impact on women's entrepreneurial process in developing countries. In this chapter, we review literatures on female entrepreneurship in developing countries to show how gender role works in developing countries and especially its influence on the intention/entry/business participation and performance of female entrepreneurs.

Abstract
Purpose
The purpose of this paper is to identify how project portfolio selection (PPS) methods have evolved and which approaches are more suitable for radical innovation projects. This paper addressed the following research question: how have the selection approaches evolved to better fit within radical innovation conditions? The current literature offers a number of selection approaches with different and, in some cases, conflicting nature. Therefore, there is a lack of understanding regarding when and how to use these approaches in order to select a specific type of innovation projects (from incremental to more radical ones).
Design/methodology/approach
Given the nature of the research question, the authors perform a systematic literature review method and analyze 48 portfolio selection approaches. The authors then classified and characterized these articles in order to identify techniques, tools, required data and types of examined projects, among other aspects.
Findings
The authors identify four key features related to the selection of radical innovation projects: dynamism, interdependency management, uncertainty treatment and required input data. Based on the content analysis, the authors identified that approaches based on different sources and nature of data are more appropriated for uncertain conditions, such as behavioral methods, information gap theory, real options and integrated approaches.
Originality/value
The research provides a comprehensive framework about PPS methods and how they have been evolving over time. This portfolio selection framework considers the particular aspects of incremental and radical innovation projects. The authors hope that the framework contributes to reinvigorating the literature on selection approaches for innovation projects.

Abstract
Purpose
The purpose of this paper is to present the author's view of the role of entrepreneurial marketing (EM) as a strategy to address the dynamic marketing environment of recent times.
Design/methodology/approach
The author reflects on some significant marketing changes and provides some contemporary example of companies that have successfully adopted EM approaches and challenged traditional marketing wisdom.
Findings
EM is best conceived not as a nexus between marketing and entrepreneurship, but as an augmented process, where both the entrepreneur and the customer are the core actors, co‐creating value within the marketing environment.
Originality/value
While this is an opinion piece, the paper provides evidence of how EM can be adopted and applied by entrepreneurial firms and challenges marketers to create and control their own‐marketing environment.
