Selection of people who will deal with management is crucial for the successful operation of any organization. This process involves respecting all relevant skills that candidates should possess, character traits, attitudes, and respect for the authority of the candidate by the group he or she should manage. The reason for conducting an adequate managerial selection procedure is the numerous findings that there are many management problems, but that there are very few sufficiently efficient managers. The aim of this paper is to point out the characteristics that need to be identified during the selection of managers in order to achieve successful business results.

Abstract. In the construction of scales intended for the use in cross-cultural studies, the selection of items needs to be guided not only by traditional criteria of item quality, but has to take information about the measurement invariance of the scale into account. We present an approach to automated item selection which depicts the process as a combinatorial optimization problem and aims at finding a scale which fulfils predefined target criteria – such as measurement invariance across cultures. The search for an optimal solution is performed using an adaptation of the [Formula: see text] Ant System algorithm. The approach is illustrated using an application to item selection for a personality scale assuming measurement invariance across multiple countries.

Selection of antibodies using phage display involves the preliminary cloning of the repertoire of sequences encoding antigen-binding domains into phagemid, which is considered the bottleneck of the method, limiting the resulting diversity of libraries and leading to the loss of poorly represented variants before the start of the selection procedure. Selection in cell-free conditions using a ribosomal display is devoid from this drawback, however is highly sensitive to PCR artifacts and the RNase contamination. The aim of the study was to test the efficiency of a combination of both methods, including pre-selection in a cell-free system to enrich the source library, followed by cloning and final selection using phage display. This approach may eliminate the shortcomings of each method and increase the efficiency of selection. For selection, alpaca VHH antibody sequences suitable for building an immune library were used due to the lack of VL domains. Analysis of immune libraries from the genes of the VH3, VHH3 and VH4 families showed that the VHH antibodies share in the VH3 and VH4 gene groups is insignificant, and selection from the combined library is less effective than from the VHH3 family of sequences. We found that the combination of ribosomal and phage displays leads to a higher enrichment of high-affinity fragments and avoids the loss of the original diversity during cloning. The combined method allowed us to obtain a greater number of different high-affinity sequences, and all the tested VHH fragments were able to specifically recognize the target, including the total protein extracts of cell cultures.

Abstract Gradient boosting from the field of statistical learning is widely known as a powerful framework for estimation and selection of predictor effects in various regression models by adapting concepts from classification theory. Current boosting approaches also offer methods accounting for random effects and thus enable prediction of mixed models for longitudinal and clustered data. However, these approaches include several flaws resulting in unbalanced effect selection with falsely induced shrinkage and a low convergence rate on the one hand and biased estimates of the random effects on the other hand. We therefore propose a new boosting algorithm which explicitly accounts for the random structure by excluding it from the selection procedure, properly correcting the random effects estimates and in addition providing likelihood-based estimation of the random effects variance structure. The new algorithm offers an organic and unbiased fitting approach, which is shown via simulations and data examples.

This paper deals with the problem of selection the most suitable trip-modelling tool (TMT), which is a part of the more complex integrated transport planning system (ITPS) at the regional scale. Since an application of TMT is not autonomous and several different users exist the selection problem is not a trivial. In this paper, an original five-phase selection procedure is presented. The first phase consists in specifica¬tion of both, detailed expectations of all identified users and technical requirements of ITPS. Second phase deals with research on available TMT while a third one is concentrated on defining a comprehensive set of criteria. In this phase critical criteria as well as selection criteria are defined. First one is utilised to eliminate unacceptable TMTs in phase four and second one to evaluate and select most adequate TMT in phase five. In the paper an exemplary application of this procedure is presented. The authors have defined 2 critical criteria and a set of 19 selection criteria. The last one is divided into 3 main subsets, i.e. functional, technical and financial contexts of selection process. All the selection criteria are characterised by 43 sub-criteria and some of them are more detailed extended. Using this procedure 3 out of 6 alternative TMTs including Emme, Aimsun and Visum have been initially accepted and next evaluated. Finally, Visum has been selected and recommended for application into ITPS.

Process selection as a part of CAPP has captured significant attention in CAPP research. Procedures have been developed for backward and forward algorithms in process selection. Most of these procedures lack the complete integration of process selection into CAPP system. In this paper, we present the results of the development and prototype implementation for process selection module for hole making operations for integration with Math Based Manufacturing System already in use in industrial partner. We have developed architecture and implemented module for rule-based machining process selection of hole making operations. The architecture enables the interface from the Process Selection prototype to Math Based Manufacturing System (APPS). The prototype also includes the user interface for interaction with the process selection procedure. Actions for starting prototype from APPS, performing process selection steps and sending the result back to APPS have been developed and implemented.

The relevance of the article is caused by the necessity to use information technologies and digital methods during the selection and launch of regional participatory projects. The objective of the paper is to develop technical task pattern for PIMS of LISP projects with the emphasis on launching models and appropriate selection procedure for participatory projects that are to obtain the interbudgetary transfer in the form of grant. The article gives more accurate definition of the term «participatory project» in the area under study. The study demonstrates the best examples of IT use during the launch and selection of regional participatory projects. The paper sets out the key requirements to the participatory projects data management system. The results of the study are practically relevant for the government, project managers and scientists, engaged in digital economics and management.

In this book, “ethics” is a general term for concerns about what people should do. The term “ethics” comes from the Greek word ethike, which means “character.” Indeed, the ancient Greeks conceived issues about what people should do in terms of impact upon character—whether people were of good or bad character (Aristotle, 350 BCE). Our concern with good reputation reveals this kind of thinking, but bad actions and bad performance can be more important than any amount of good reputation if they are bad enough. Not even the most capable network troubleshooter could survive the discovery of large amounts of downloaded kiddie porn on his workstation. William Bennett’s A Book of Virtues (Bennett, 1993) is a more recent example of a character-based ethics very similar to Greek ethics. The central term of Greek ethics, ethike arête, is usually translated as “virtue”—the literal meaning is “excellence of character.” “Good character traits” is probably the nearest translation. Bennett’s list of virtues or good character traits includes: self-discipline, compassion, responsibility, friendship, work, courage, perseverance, honesty, loyalty, and faith. His selection of virtues overlaps with the classic Greek virtues or good character traits. Plato’s list was: courage, temperance, wisdom, and justice. (Plato, 360 BCE). Aristotle added liberality, pride, good temper, friendliness, truthfulness, and ready wit. Although all of these—Plato’s, Aristotle’s, and Bennett’s—are good character traits to have, having them doesn’t answer many important questions about what actions to do, especially when virtues conflict. Is perseverance in constructing a computer virus a good thing? Clearly the rightness or wrongness of the action in which we are persevering is very important. Or what about loyalty to an organization ripping off poor people? Here honesty (and compassion) may be more important than loyalty and responsibility. Indeed, Bennett’s list omits justice, considered the most important virtue by Plato. Since justice is primarily a virtue of institutions rather than individuals, Bennett’s list leaves out issues about how well society is arranged. We have made some progress on these issues since Greek times.1 The point is that character-based ethics is incomplete. Bennett himself, in replying to critics of his compulsive gambling behavior, seems to believe that as long as an individual has the “virtues,” that is, the good character traits, then other actions are irrelevant. Most of the rest of us in these non-classic-Greek times believe otherwise. Nowadays, “ethics” is an inclusive term for concerns also referred to as “morality,” “value,” and “justice.” Besides character, ethics in this inclusive sense is also concerned with the rightness and wrongness of actions, the value or goodness of things and situations, and with the justness of institutions. The basic terms of ethics are: right, good, and just.

We observe a sequence {Xk } k≧1 of i.i.d. non-negative random variables one at a time. After each observation, we select or reject the observed variable. A variable that is rejected may not be recalled. We want to select N variables as soon as possible subject to the constraint that the sum of the N selected variables does not exceed some prescribed value C > 0. In this paper, we develop a sequential selection procedure that minimizes the expected number of observed variables, and we study some of its properties. We also consider the situation where N → ∞and C/N → α > 0. Some applications are briefly discussed.

The validity and credibility of assertions on the efficiency and equity of selection procedures is dependent on the methodology with which the procedure was developed and justified. An ideal approach to the development and justification of a selection procedure was derived from standard guidelines and operationalized in the form of a comprehensive checklist. A psychometric audit on the developmental history of the selection procedure for the selection of commission advisors was undertaken. Various shortcomings were identified and rectified or recommendations were made on rectifying them. The audit found that the selection procedure had zero validity, negative utility and discriminated unfairly. Opsomming Die geldigheid en geloofwaardigheid van uitsprake oor die effektiwiteit en billikheid van ‘n keuringsprosedure is ‘n funksie van die metodologie waarmee die prosedure ontwikkel en regverdig is. ‘n Ideale benadering tot die ontwikkeling en regverdiging van ‘n keuringsprosedure is uit standaard riglyne afgelei en geoperasionaliseer in die vorm van ‘n omvattende kontrolelys. ‘n Psigometriese oudit is onderneem op die ontwikkelingsgeskiedenis van ‘n keuringsprosedure vir die keuring van kommissie-adviseurs. Verskeie tekortkominge is geïdentifiseer en reggestel of aanbevelings ten opsigte van regstelling is gemaak. Die oudit het bevind dat die keuringsprosedure oor zero geldigheid beskik, negatiewe nutwaarde toon en onbillik diskrimineer.
