<p class="p1">Ab initio molecular orbital calculations on the interaction between Copper(I) and 5-nitrotetrazolate anion were done using different basis sets, at the HF, B3LYP and MP2 levels of theory. Three minima were found to 1A, 1B and IC structures of Cu(I)-5-NTz complex. At the B3LYP/LanL2DZ level, the energy difference between 1A and 1B was computed to be 8.18 kcal/mol, while that between 1A and 1C is 22.76 kcal/mol. The presence of both Cu-N and Cu-O interactions is revealed in 1A structure using both natural bond orbital and atoms-in-molecules analyses, which makes more stable than those of 1B and 1C complexes. The binding energy corrected for both ZPE and BSSE for 1A is found to be -150.59 kcal/mol at the B3LYP/LanL2DZ level. The barrier for the 1B <span class="s1">→</span> 1A and 1C <span class="s1">→</span> 1B conversion is calculated to be 7.80 kcal/mol and 9.40 kcal/mol, respectively.</p>

AbstractThis article comments on the above‐titled article which appeared in Public Administration and Development (PAD), Vol. 12. It argues that Hulme's article: (i) does not, as it professes to, bring out the organizational impact of the training and visit (T&V) system of extension and, more seriously, does not suggest what improvements are needed to the system, and whether any such improvements have been tried anywhere and with what results; (ii) dismisses the rigorous statistical analysis of the impact of the system by Feder and Slade, and approvingly cites Antholt's methodologically unsustainable comparison between states in India, without giving convincing reasons for this choice; and (iii) ignores the important developments regarding T&V extension in the recent past, and relies on earlier papers on the subject. Some of the recent developments regarding the implementation of T&V in Africa are given in this article, including a summary of recent evaluations done in Kenya and Burkina Faso. The article concludes with an account of the managerial issues posed by T&V.

Es handelt sich um eine Replik auf die Kritik von David Hulme in dieser Zeitschrift 1992. Knapp wird über die jüngste Ausweitung des "Training and Visit"-Programms und die inzwischen erworbenen Erfahrungen in Asien und Afrika berichtet. Die zugrunde liegende Annahme ist, daß es durch Regelungen im Organisationsbereich möglich ist, auch technische Fragen anzugehen. Der Verfasser kritisiert, daß Hulmes Ausführungen keine diesbezüglichen positiven Anregungen enthalten. (APAF-Glz)

Purpose
– Bankruptcy is a financial failure of a business or an organization. Different kinds of bankruptcy prediction techniques are proposed to predict it. But, they are restricted as techniques in predicting the bankruptcy and not addressing the associated activities like acquiring the suitable data and delivering the results to the user after processing it. This situation demands to look for a comprehensive solution for predicting bankruptcy with intelligence. The paper aims to discuss these issues.


Design/methodology/approach
– To model Business Intelligence (BI) solution for BP the concept of reference model is used. A Reference Model for Business Intelligence to Predict Bankruptcy (RMBIPB) is designed by applying unit operations as hierarchical structure with abstract components. The layers of RMBIPB are constructed from the hierarchical structure of the model and the components, which are part of the reference model. In this model, each layer is designed based on the functional requirements of the Business Intelligence System (BIS).


Findings
– This reference model exhibits the non functional software qualities intended for the appropriate unit operations. It has flexible design in which techniques are selected with minimal effort to conduct the bankruptcy prediction. The same reference model for another domain can be implemented with different kinds of techniques for bankruptcy prediction.


Research limitations/implications
– This model is designed using unit operations and the software qualities exhibited by RMBIPB are limited by unit operations. The data set which is applied in RMBIPB is limited to Indian banks.


Originality/value
– A comprehensive bankruptcy prediction model using BI with customized reporting.

Purpose
– Business intelligence (BI) has been applied in various domains to take better decisions and it provides different level of information to its stakeholders according to the information needs. The purpose of this paper is to present a literature review on recent works in BI. The two principal aims in this survey are to identify areas lacking in recent research, thereby offering potential opportunities for investigation.


Design/methodology/approach
– To simplify the study on BI literature, it is segregated into seven categories according to the usage. Each category of work is analyzed using parameters such as purpose, domain, problem identified, solution applied, benefit and outcome.


Findings
– The BI contribution in various domains, ongoing research in BI, the convergence of BI domains, problems and solutions, results of congregated domains, core problems and key solutions. It also outlines BI and its components composition, widely applied BI solutions such as algorithm-based, architecture-based and model-based solutions. Finally, it discusses BI implementation issues and outlines the security and privacy policies adopted in BI environment.


Research limitations/implications
– In this survey BI has been discussed in theoretical perspective whereas practical contribution has been given less attention.


Originality/value
– A comprehensive survey on BI which identifies areas lacking in recent research and providing potential opportunities for investigation.
