Abstract

Purpose

The purpose of this paper is to present the optimal design of a simply supported variable curvature laminated angle-ply composite panel under uniaxial compression. The objective is to maximize the failure load which is defined as the minimum of the buckling load and the first-ply failure load.

Design/methodology/approach

The numerical results presented are obtained using a shear deformable degenerated shell finite element, a brief formulation of which is given. Some verification problems are solved and a convergence study is conducted in order to assess the accuracy of the element. The design procedure is presented and optimization results are given for a simply supported symmetric eight layer angle-ply panel composed of a flat and two cylindrical sections.

Findings

The influences of the stacking sequence and panel thickness on optimization are investigated and the effects of various problem parameters on the optimization procedure are discussed.

Originality/value

The paper shows that the load carrying capacity of thicker panels is considerably reduced when the first-ply failure constraint is taken into account.

Abstract

Purpose — The purpose of this paper is to assess the accuracy of homogenization or the smeared stiffness approach in analyzing quadrigrid plates under transverse loads is assessed by comparing two distinct finite element solutions. The grid is assumed to be made of homogeneous isotropic material. However, the numerical solution procedure adopted here is applicable to grids made of unidirectional composite ribs. Design/methodology/approach — The finite element structural analysis is conducted by using plate elements based on the first‐order shear deformable theory (FSDT) and grillage analysis using first‐order shear deformable beam elements. The grillage analysis results, which are taken as the exact results, are compared with the approximate results obtained using FSDT plate elements, where the stiffness matrices obtained by the smeared stiffness approach are incorporated in the plate finite element formulation. Several sample problems are solved and the influences of rib spacing, rib thickness‐to‐width ratio, plate dimensions, and loading are examined. Findings — The results presented here show that homogenization yields reliable results when certain conditions are satisfied. Originality/value — The paper demonstrates that it is necessity to conduct thorough and systematic research studies revealing the accuracy of these models, as the applicability limits of homogenization are not clearly known.

Abstract

The current Industry 4.0 era is considered not only as a process that dominates technological developments but also as a process that influences the leadership styles. Management 4.0 is essential for businesses to find and apply the appropriate technologies in the age of Industry 4.0. The leadership styles that business managers will adopt in order to be successful in this process and to survive in an intensely competitive environment can play an important role. At this point, a significant problem arises: identifying leadership styles that will bring success. In this context, the primary purpose of this chapter is to explain the modern leadership styles that business managers can adopt or follow in the age of Industry 4.0. In line with this purpose, the chapter first describes the historical development of leadership, leadership theories and modern leadership styles, such as transactional, transformational, technological, strategic, visionary and agile leadership, and all these concepts are discussed based on the Industry 4.0 perspective.

Abstract

Purpose

There has been a rapid generational change in the business world in Turkey recently, and X generation managers are rapidly leaving their place to Y generation managers. In countries with relatively young populations such as Turkey, management in family businesses passes into the hands of Generation Y. This study aims to examine the moderator role of the difference between old and new generation Y in the effect of self-efficacy perceptions on decision-making strategies.

Design/methodology/approach

This research, which was designed according to the quantitative research method, was designed according to the cross-sectional survey model, one of the general survey models. The research data were collected from a sample of 441 family business managers determined according to the simple random sampling technique. The data were analyzed and interpreted with various statistical techniques. Data analysis was done with AMOS. 20 and International Business Machines statistical package for the social sciences 22 data analysis programs.

Findings

According to the analysis findings, there is a significant relationship between the participants’ self-efficacy perceptions and decision-making strategies. Research findings old and new generation Y managers have different decision strategies. The research results showed that the dominant self-efficacy perceptions of the Y generation affect their decision-making strategies.

Research limitations/implications

This research only examines whether the old and new generation Y perceptions have a moderator function in the relationship between the participants’ self-efficacy perceptions and decision-making strategies. The research is quantitative research limited to family businesses. The results can be compared by repeating the research with other variables and in different samples, for example, by researching in public institutions. In addition, the way of reflecting the differences in perception to the management can be subjected to deeper analysis with mixed studies.

Practical implications

One of the important reasons for the difference in people’s approaches to events is their personality structure. Generational differences, which have been discussed primarily in recent years, make themselves felt in working life. The new working models arising from the different perspectives of the Y generation differ from the traditional business models. Today, in traditional business models, the manager profile is usually the X generation. However, the process is moving toward gaining essential positions in the management levels of the new Y generation. They put traditional managers in a difficult situation with their impatient behavior and desire to climb the career ladder quickly.

Social implications

In the studies conducted on the Y generation, it is understood that they do not favor the classical management approach based on the command-command relationship. The sense of loyalty of the Y generation is low compared to other generations and their organizational commitment levels are weak. There are determinations that they attach importance to flexible working style and want to do business using digital technologies. They are highly motivated in setting vision and participating in strategic decisions in organizations. These features differ significantly from the X-generation managers who adopt the traditional management approach.

Originality/value

Both emotional and cognitive characteristics influence decision-making behavior. The generation gap which shows common personality structures in a certain period is an important predictor of decision-making strategy. Research results and related studies significantly affect the decision strategies of the generation gap. No research has been found comparing the old and new Y generations. In this respect, it is thought that the research will contribute to theory, practice and method.

Abstract

Purpose

This study aims to analyse current practices and cooperation between the Turkish university libraries related to cataloguing processes and present cataloguing librarians’ evaluations about clarity and comprehensiveness of the given information in library catalogues.

Design/methodology/approach

In line with the literature review, a Web-based questionnaire was developed concerning the cataloguing practices implemented at university libraries in Turkey. The questionnaire was submitted to 316 cataloguing librarians. In all, 104 cataloguing librarians from 61 different libraries responded to the survey. The collected data were analysed through descriptive statistics. The responses given to some open-ended questions were assessed with respective expressions presented verbatim in the study and some of them visualised via VOSViewer software.

Findings

The findings reflect that analysed university libraries implement different cataloguing processes. It is seen that some libraries use the necessary systems and services related to cataloguing and classification while others use individual solutions without using such systems and services. Findings reveal that there is cooperation between the analysed libraries about sharing catalogue records. In this regard, it is understood that cataloguing librarians mostly prefer transferring catalogue records from the catalogues of university libraries they trusted. Findings also indicate that analysed librarians think that the descriptive information provided via Online Public Access Catalogues are in moderate level in terms of clarity and comprehensibility.

Originality/value

The study contributes to the existing literature of a limited number of relevant studies by establishing the baseline pertaining to cataloguing processes undertaken at university libraries in Turkey.

Abstract

The aim of this qualitative study was to determine what makes school principals successful. The study obtained data through interviews, both face-to-face and via e-mail correspondence. Content analysis provides the framework for analyzing the data. The data revealed that successful school principals have three different, but interrelated competencies, which are personal, administrative, and leadership competencies. The study also indicates that those successful principals gave priority to human relations, they see the school as their home where principals created a warm atmosphere, communicated effectively with all stakeholders, committed themselves to their schools, managed schools in a democratic way, solved problems on time and effectively.

Abstract

Purpose

The purpose of this paper is to investigate the preschool teachers’ cultural intelligence, their attitudes towards multicultural education and the correlation between these two variables.

Design/methodology/approach

The sample consisted of 203 preschool teachers working in preschool classes within primary schools administrated by the Ministry of Education in Turkish Republic of Northern Cyprus (TRNC). Data were collected from the teachers by cultural intelligence scale (CQS), teacher multicultural attitude survey (TMAS) and demographic information form.

Findings

The analysis revealed that cultural intelligence and attitudes towards multicultural education did not differ according to teaching experience in a foreign country. Significant differences were found in metacognition, motivation and behaviour sub-dimension scores, cultural intelligence total scores and multicultural education attitude scores because of having a friend in foreign country, cognition sub-dimension scores because of having a non-Turkish-speaking student (NTSS) in class and cultural intelligence total scores because of knowing a foreign language. Significant relation was found between cultural intelligence scores and multicultural education attitude scores of the participants.

Originality/value

Despite the increasing cultural diversity in the country, there are no official regulations or efforts to establish arrangements for multicultural education in TRNC. Thus, this research is valuable for clarifying the situation in TRNC, determining the requirements and providing insights for future scientific work and implications.
