The purpose of this paper is to present a new constrained optimization algorithm based on a particle swarm optimization (PSO) algorithm approach.
Abstract
Purpose
The purpose of this paper is to present a new constrained optimization algorithm based on a particle swarm optimization (PSO) algorithm approach.
Design/methodology/approach
This paper introduces a hybrid approach based on a modified ring neighborhood with two new perturbation operators designed to keep diversity. A constraint handling technique based on feasibility and sum of constraints violation is adopted. Also, a special technique to handle equality constraints is proposed.
Findings
The paper shows that it is possible to improve PSO and keeping the advantages of its social interaction through a simple idea: perturbing the PSO memory.
Research limitations/implications
The proposed algorithm shows a competitive performance against the state‐of‐the‐art constrained optimization algorithms.
Practical implications
The proposed algorithm can be used to solve single objective problems with linear or non‐linear functions, and subject to both equality and inequality constraints which can be linear and non‐linear. In this paper, it is applied to various engineering design problems, and for the solution of state‐of‐the‐art benchmark problems.
Originality/value
A new neighborhood structure for PSO algorithm is presented. Two perturbation operators to improve PSO algorithm are proposed. A special technique to handle equality constraints is proposed.

Abstract
Menger disagreed with this view for various reasons. Also, the subjective expectation is infinite. There are many cases where man's behaviour fails to conform to mathematical expectations: games in which a player can win only one very large amount with a very small probability or games offering a single moderate amount with a very high probability. Furthermore, we can always find a sequence of payoffs x1, x2, x3,…, which yield infinite expected value, and then propose, say, that u(xn)=2n, so that expected utility is also infinite. Menger therefore proposed that utility must also be bounded above for paradoxes of this type to be resolved.

Abstract
Prior research on the structure‐performance relationship has not investigated all of the relevant relationships among market structure, profits, prices, and explicitly calculated measures of firm efficiency. This paper replicates the four approaches in the literature, adds several innovations, and applies the analysis to banking data. We find more support for the structure‐conduct‐performance hypothesis than for the relative‐market‐power and efficient‐structure hypotheses, although the data are not fully consistent with any of these theories. We also find support for Hick's quiet‐life hypothesis, which implies that firms with market power adhere less rigorously to efficiency maximization. J.E.L.

Abstract
Competence in written communication has been described as a fundamental underpinning of contemporary undergraduate education by both educational advisors and agencies. This article focuses on students’ perceptions of their own writing styles and skills. These opinions have been considered in the context of the desires and expectations of practitioners in public relations for high standards of grammar, variety in copywriting style and a high degree of accuracy in writing. Students’ perceptions of the learning environment for this vocational academic discipline also suggest a receptiveness to the integration of alternative pedagogues in the form of information technology.

Abstract
Purpose
This study examines principal rotation in China to gain empirical insights from the policy analysis and succession strategies that principals employ to gain internal and external support in their new schools.
Design/methodology/approach
We employed document analysis and a case study approach. Interviews were conducted with officials in 5 local educational agencies and 40 principals from 5 different regions who were undergoing rotation. Thematic analysis was used to identify common patterns and themes in the interview responses.
Findings
We explored how the principal-rotation policy was implemented, including the goals, standards, targeted principals, tools and other aspects of the policy in China. The study revealed the challenges faced by the rotated principals and their succession strategies.
Originality/value
Our study contributes to the field of educational leadership by shedding light on the implementation and impact of principal rotation in mainland China.

This study addresses how algorithmic recommendations and their affordances shape everyday information practices among young people.
Abstract
Purpose
This study addresses how algorithmic recommendations and their affordances shape everyday information practices among young people.
Design/methodology/approach
Thematic interviews were conducted with 20 Finnish young people aged 15–16 years. The material was analysed using qualitative content analysis, with a focus on everyday information practices involving online platforms.
Findings
The key finding of the study is that the current affordances of algorithmic recommendations enable users to engage in more passive practices instead of active search and evaluation practices. Two major themes emerged from the analysis: enabling not searching, inviting high trust, which highlights the how the affordances of algorithmic recommendations enable the delegation of search to a recommender system and, at the same time, invite trust in the system, and constraining finding, discouraging diversity, which focuses on the constraining degree of affordances and breakdowns associated with algorithmic recommendations.
Originality/value
This study contributes new knowledge regarding the ways in which algorithmic recommendations shape the information practices in young people's everyday lives specifically addressing the constraining nature of affordances.

Abstract
Purpose
The purpose of this paper is to discover and enumerate the elements of the digital library and measure how much an individual library was equipped with the characteristics of the digital library accordingly.
Design/methodology/approach
For this purpose several steps were taken. First, research on the characteristics and the representative services of the digital library were comprehensively reviewed. Second, examples of the library services that were being considered for the next generation digital library were investigated to compare with the conventional library services. Third, the elements of the conventional and the digital libraries initially extracted were examined by ten experts. These experts were composed of researchers and professors specializing in digital libraries, and career librarians who had worked in the digital library field for at least ten years. The elements were verified through discussions with them. Fourth, 19 university libraries, 16 public libraries, and 17 special libraries were selected in accordance with the verified elements of the conventional and the digital libraries to measure the digitization level of the libraries.
Findings
The following is a summary of the evaluation of the first eight evaluation items, which are covered in Part 1 of this study. The remaining five items will be covered in Part 2. First, the digitization level of the acquisition element and classification and cataloguing was significantly high. Second, book collections excluding “digital video,” reference service, library program service, and space service showed significantly conventional characteristics. Third, in the element of circulation services, the item of lending books offline and returning the books scored 92.64 and the item of lending-returning with use of smart devices and social media obtained significantly low scores. Also, the average in using the book return desk for the circulation service was 81.39, much higher than using the automatic book return machine, which scored 18.61, by a wide margin. Fourth, in the element of user services, the digital item of providing support for mobile services related to the library resources demonstrated higher scores than the conventional item, but other items showed more conventional characteristics. In particular, the item of duplication services for material scored 94.99, but other items such as support for publication/bookbinding services using digital publication tools and devices obtained significantly low scores.
Originality/value
This study is first study in the world to measure the level of digitization of the library. Therefore, hereafter, each library will be able to measure and determine its digital position based on these elements. Up to now, some research was performed in pursuit of extracting the elements of a library but it has relied solely on literature review. Comprehensive research had never been performed as in this study.

Abstract
Purpose
To investigate the effects of regulations, macroeconomic changes, and political events on the efficiency of the Turkish banks during the period 1997-2013, when crucial changes were experienced. To analyze the effects of an extensive set of bank-specific and environmental factors on the efficiency, since the diversions could not only be related to new regulations.
Design/methodology/approach
A two-stage procedure is employed. First, the productivity changes of each bank and of the whole sector are measured by a DEA-based Malmquist Productivity Index (DEA-MPI). Second, the effects of selected internal and external factors on productivity are analyzed with regression analysis. The sector is especially handled before and after 2001, when one of the most catastrophic crises is observed and moment after which a series of new regulations are implemented.
Findings
During the period 1997-2001, the efficiency deteriorated due to the 2001 crisis; after the crisis, an improvement was observed. All models indicate the source of improvements as efficiency instead of technological changes. Rather than external, internal factors seem to be more effective on productivity. Therefore, the importance of regulations for the soundness of banks, management quality and monitoring may be more crucial than what is thought. In general, a new macroeconomic environment, particularly new regulations, have positive effects on productivity. Tighter regulations, monitoring, restrictions, strong supervision, more capital, and new reforms have a positive impact on efficiency.
Originality/value
The study spans a wide period to analyze the sector using three different perspectives. It analyzes the effect of the 2001 financial crisis and subsequent regulations. It handles an extensive set of internal and external factors; and it tests each factor with nine different DEA-MPI models for consistency. Turkey's unique environmental factors, such as the unstable macroeconomic conditions, high inflation and a subsequent disinflation period, high interest rates, new regulations and crisis experience, among others, also make the study distinctive.
