Notwithstanding Karl Popper’s deep admiration for ancient Greece and his affection for modern Greece, his work has been mostly viewed with caution by Greek scholars who, until relatively recently, often chose to either ignore or downplay it. This stance can be partially attributed to the novel approach of Popper’s critique to Plato which did not fare well with the foundational biases of modern Greek academic tradition and the prevailing intellectual inclinations of Greek scholars in the fields of the methodology of science and political theory. Although this bias has begun to recede during the last decades, there remains a lot to be done to fully integrate Popper’s work into the Greek intellectual and social discourse. Nevertheless, the establishment of the Department of History and Philosophy of Science at Athens University, along with the efforts of academics and public intellectuals, particularly during the Greek financial crisis of the last decade, have played a pivotal role in generating a broader interest in critical rationalism and popularizing Popper’s ideas among a wider audience. This paper examines the evolution of the reception of Popper’s ideas in Greece, both in scholarly circles and in public life, from the time of publication of his seminal work “The Open Society and its Enemies” until today, highlighting the efforts to foster a more comprehensive understanding of his important contributions

The reception and influence of Popper’s philosophy of science and his political philosophy in Latin America have depended heavily on the translation of his major works originally published in German and English. Thus, for example, The Logic of Scientific Discovery, which was originally published in 1959, was translated into Spanish in 1962 and into Portuguese only in 1974. Similarly, The Open Society and Its Enemies, originally published in 1945, was translated into Spanish twelve years later in 1957 and into Portuguese in 1974. But apart from a discussion of the impact of the translations of his books, I also want to show that the political situation in some Latin American countries, for example, Chile, Cuba and Peru, has played a very important role in the introduction, reception and influence of Popper’s philosophy of science in general and his social and political thought in particular. Accordingly, the main purpose of this article is to examine the reception of Popper’s ideas in Latin America and give an account of his influence and legacy in some of the Latin American countries such as Argentina, Brazil, Chile, Colombia, Cuba, Mexico, Peru and Uruguay.

Critical rationalism faces difficulty in Karl Popper’s Socratic formulation: “I may be wrong, and you may be right, and by an effort, we may find the truth.” But the Socratic elenchus, using refutations, can only give us negative knowledge of general principles, which is not the wisdom we seek. Affirmatively, we can only find a collection of opinions to be coherent, which is one of many. Francis Bacon proposed an improved elenchus to find general truths. You must take up a limited topic to study, then cross-examine your evidence for and against its apparent nature. Experiments contrary to evidence and presumed knowledge are entered as self-contradictions in tables of opposition recorded in an “experimental and natural history.” Such an account highlights a challenging puzzle if the account is to be made coherent. With enough problematized evidence, a coherent reading, or a solution of the puzzle, will be unique. Being both coherent and unique, it will be the truth about that limited reality being investigated. Unlike the method of hypothesis (“Anticipating Nature”), deciphering a coherent model is “Interpreting Nature,” allowing us to find a general truth on a limited topic. Isaac Newton achieved great success using Robert Boyle’s mechanistic version of this method. Using the “experimental philosophy,” he discovered general principles of optics and astronomy.

Our analysis of Popper’s philosophy of science focuses on his concepts of tradition and situational analysis. These concepts represent innovative Popperian contributions to a historical and hermeneutical turn in philosophy of science that most of his critics, especially Kuhn, fail to recognize. According to his historical view, Popper conceives sciences as a complex of traditions in continuous transformation and progress by means of rational discussion of theories. In order to grasp the rational progress of scientific traditions, Popper proposes an original method that he calls “situational analysis”. This hermeneutical method seeks to understand the concepts, hypotheses, actions, practices, controversies and products that scientists made to solve problems in their specific historical contexts to improve the truth content of theories. In addition to his historical and hermeneutical turn, Popper also inquired about the social and political conditions for the progress of scientific traditions by means of intersubjective criticism of theories and conjectures. According to him, the rational discussion of ideas requires, as necessary conditions, plurality of ideas, intellectual humility, and freedom of thought and communication that can only exist in an open and democratic society. With these considerations, we may say that in addition to a historical and hermeneutical turn, Popper also contributed to a social and political turn in the philosophy of science

The paper offers a distinctive reading of Popper’s work, suggesting that his Logic of Scientific Discovery (LScD) might be re-interpreted in the light of his Open Society. Indeed, Popper can be interpreted as criticising certain aspects of his first book, and as a result improving upon them, in his second. It suggests translating what Popper says about ‘conventions’ into his later vocabulary of ‘social institutions’. Looking back, I believe that Popper never intended the language of conventions and decisions to be read individualistically. I remain unsure whether Popper was himself quite as clear about this as he could have been.  My reading makes Popper a pioneer in the sociology of science. Scientific institutions are arenas of political power; but Popper did not discuss the structure and inter-relations of the social institutions of science, or offer a politics of science in the context of his methodology. What is missing from the skeletal sociology of LScD is the politics. We could put it in Popperian terms this way: scientific institutions are both open and closed. They are closed, firmly, to the inexpert, to the non-members; supposedly they are open to the qualified, provided the prerogatives of seniority and leadership are acknowledged. Despite these shortcomings, Popper’s critical and rational approach and his insistence on openness and intellectual honesty are still important today.

In this paper, I address the issue of the possible applicability of the ideas of Karl R. Popper’s social and political philosophy in the contemporary political life of postcolonial countries. Through reference to the reception of Popper’s philosophy in Central and Eastern Europe, I argue that Popper’s writings were effective in catalysing the political wholesale transformation by undermining Marxists’ pretensions to scientific status rather than through his anti-utopian and anti-revolutionary political recommendations. In the context of attempts to apply Popper’s ideas in postcolonial countries, especially Sub-Saharan Africa, I claim that the influence of Popper’s social thought on the politics of those countries may not be as effective as expected or desired.

The asymmetry of information between managers and shareholders significantly affects the company's investment decisions and exacerbates the problems of agency. It seems that these problems in developing markets such as Iran are more than developed markets. This research is an exploratory study, and it aims at reviewing the theory of agency in Iran. In the present study, based on the research paradigm, first, data acquisition strategy is selected based on a qualitative approach, and then qualitative study and analysis, quantitative approach, and factor analysis approach have been used to confirm the validity of the extracted model. Statistical analysis of research data shows that among the hypotheses of agency theory, risk aversion, supervision, and reward are revised dimensions in Iran like examples of developing countries.The results confirm the existence of assumptions; 1. Conflict of interests of manager and owner, 2. Information asymmetry, 3. Reverse choice, 4. Ethical risk, 5. Maximizing the expected utility, 6. Forcing and 7. Failure to confirm the assumption is the ability to predict the future and receive information. due to the existence of information asymmetry, higher investment risks of minority shareholders and transparency problems, the lack of ability to predict the future and receive information is necessarily confirmed.

Nowadays, many companies cannot see the digital investment that plays a main role in the IR 4.0. Therefore, this study is investigating the study of investment as plays a critical role in an analytical activity to assess the benefits and costs of an investment and can be used as an investment justification. Traditional investment appraisal uses a financial approach where the benefits and costs are quantified in a certain amount of value for money and then compared in value. Moreover, this study is revealed the fruitful outcomes because revealed the investment valuation method with NPV (Net Present Value) and ROV (Real Option Valuation). ROV is an alternative to financial valuation. Seeding from the same philosophy as Financial Option, ROV has advantages in handling the flexibility, risk, and volatility that may occur from an investment. Thus, ROV is considered more able to appreciate an investment that has these characteristics. Investment appraisal with ROV is better able to appreciate investment than traditional financial methods, as shown by ROV's NPV results in the case of marketing with Loyalty points through email communication as a digital investment that are greater than ordinary NPV. This is because ROV can appreciate flexibility in investments that have choices of investment plans in the future
