Choice experiment (CE) is a questionnaire based method that the accuracy of research questionnaire determines the validity of the research outcomes. Attribute selection has a prime importance in every CE studies. If respondents do not understand or do not have preference for a certain attribute, the attribute non-attendance problem might happen that biases overall results of the research. Qualitative approaches such as literature review, focus group discussion, and in depth discussion commonly applied in CE researches. However, especially in the developing (...) countries context where ethnical and cultural diversity is a challenge in conducting survey based questionnaires, qualitative methods are not sufficient in selecting attributes. Present study investigates the application of relative importance index (RII) in respondents¡¯ preference for attributes in a modal shift study in Klang Valley, Malaysia. The 5 point Likert scale questions were employed to enhance respondents¡¯ preferences for initial 24 selected attributes. The results of this study showed that from 24 pre-selected attributes, only 18 of them had RII>0.5 and could be included in the final CE design. The results of this study could help researchers to control for unobserved problems in selecting the attributes which could not be discovered through qualitative approaches. -/- . (shrink)

Modelowanie komputerowe odgrywa istotną rolę we współczesnej nauce. Epistemologiczna rola, jaką odgrywają takie modele oraz prowadzone na ich bazie symulacje skłaniają do postawienia pytań o możliwe użycie podobnych metod w filozofii. Pomysły wykorzystania narzędzi matematycznych do sformułowania koncepcji filozoficznych sięgają czasów Barucha Spinozy i Isaaca Newtona. Newtonowska filozofia przyrody stała się przykładem udanego zastosowania matematycznych rozważań do opisu przyrody na poziomie fundamentalnym. Oczywiście podejście Newtona otworzyło zarówno nowe obszary badań w fizyce, jak i stało się źródłem dla nowych rozważań o (...) rzeczywistości fizycznej. Według Michała Hellera niektóre teorie fizyczne można traktować jako specyficzne formalizacje koncepcji filozoficznych. Modelowanie komputerowe w filozofii może być traktowane jako rozszerzenie tej idei, co będę starał się ukazać w niniejszym artykule. Będę również rozważał rolę modelowania komputerowego jako źródła nowych metafor filozoficznych zgodnie z koncepcją technologii definiującej D. J. Boltera. Rozważania te wiodą do konkluzji mówiącej, że w metodologii filozofii zachodzą istotne zmiany. Nowe podejście nie sugeruje odrzucenia bądź zanegowania dotychczasowych metod, a wskazuje raczej nowe narzędzie analityczne filozofii i źródło inspirujących metafor. (shrink)

[English] This paper aims to discuss ten traditional and contemporary methodological paradigms in African philosophy, and demonstrates how they may apply to African environmental ethics research. The methods include: Ethno-philosophy, Sage Philosophy, Conversational Philosophy, Conceptual Mandelanization, Eco-Afrocentricism, Indigenous Language Analysis, Eco-Afro-feminism, Conceptual Decolonization, Storytelling Philosophy, and Cultural Adaptationism. The significance and limitations of the methodologies are highlighted. The concept and principles of African environmental ethics are analyzed and discussed to facilitate an understanding of the conceptual frameworks that underpin the methodologies. (...) In conclusion, the discourse demonstrates that environmental ethics research in Africa should be based on African philosophical methodologies so as to facilitate production of research that will be relevant in African contexts. -/- [Annang] N̄wed nduongo ami ayem ibene nwọ́d mme n̄kaan nne mfa usung unam nduongo ke vilọsọvi Afrịke , nne nte amọ ekeme iwam unam nduongo mbanga ido ukpeme nkan-nkuk ke Afrịke.

The fight against corruption has become increasingly sophisticated and such demands a well-integrated, multidisciplinary strategy. This has necessitated the establishment of anti-corruption institutions, agencies or commissions which invariably have one or more of three functions: investigation and enforcement; corruption prevention; and awareness and education. However in Ghana, despite the existence of anti-corruption institutions, the perception of corruption has steadily increased to overwhelming levels. Why the increase in corruption in the face of these anti-corruption institutions is the subject matter of this (...) study. This study brings to fore the systemic barriers, their frequency of occurrence and magnitude. This study aimed at identifying the challenges that affect the effectiveness of these anti-corruption institutions in Ghana. The study was purposely carried out within anti-corruption institutions in Ghana. A simple random probability sampling was employed in sampling nine (9) anti-corruption institutions in the Ashanti Region of Ghana and questionnaires administered to their administrative heads. Relative importance, frequency and severity equations were used to analyze and rank the challenges affecting the work of these institutions. Lack of political will and inadequate leadership and management with Relative importance Index RII of 0.9778 respectively were the two (2) most critical challenges affecting the effectiveness of anti-corruption institutions in Ghana. Lack of donor initiatives with RII of 0.6667 was considered as the least challenge. The most frequent challenge identified by the anti-corruption agencies was the lack of budget and fiscal autonomy, with an index of 0.8148. In the face of these challenges, the government of Ghana should improve upon its efforts at fighting corruption as it strengthens the various anti-corruption institutions financially and logistically.
