The aim of this paper is mainly to handle the fuzzy uncertainties present in structures appropriately. In general, uncertainties of variables are classified as aleatory and epistemic. The different sources of uncertainties in reinforced concrete structures include the randomness, mathematical models, physical models, environmental factors and gross errors. The effects of imprecise data in reinforced concrete structures are studied here by using fuzzy concepts. The aim of this paper is mainly to handle the uncertainties of variables with unclear boundaries.

To achieve the intended objective, the reinforced concrete beam subjected to flexure and shear was designed as per Euro Code (EC2). Then, different design parameters such as corrosion parameters, material properties and empirical expressions of time-dependent material properties were identified through a thorough literature review.

The fuzziness of variables was identified, and their membership functions were generated by using the heuristic method and drawn by MATLAB R2018a software. In addition to the identification of fuzziness of variables, the study further extended to design optimization of reinforced concrete structure by using fuzzy relation and fuzzy composition.

In the design codes of the concrete structure, the concrete grades such as C16/20, C20/25, C25/30, C30/37 and so on are provided and being adopted for design in which the intermediate grades are not considered, but using fuzzy concepts the intermediate grades of concrete can be recognized by their respective degree of membership. In the design of reinforced concrete structure using fuzzy relation and composition methods, the optimum design is considered when the degree of membership tends to unity. In addition to design optimization, the level of structural performance evaluation can also be carried out by using fuzzy concepts.

In a recent review of the history of women in unions, the author suggested that downturns in the economy have had a more significant effect on women than men in unions, leading to significant declines in the membership of women in unions. The purpose of this paper is to explore the relationship between economic cycles and women's membership in unions.

The paper investigates that relationship using both quantitative and historical methods and generate evidence for the proposal.

Based on the historical and quantitative analysis, it is concluded that a more accurate way to depict the situation is to say that economic conditions influence union membership through a number of important intervening variables and, furthermore, that changes in those intervening variables over the past 40 years have substantially influenced the relationship between economics and union membership.

This paper is unique in its combination of historical and empirical approaches to addressing questions of a historical nature. The paper addresses an interesting proposal regarding relationships between economics and gender in union membership

Recent studies document that approximately two-thirds of sample firms have at least one audit committee member serving on their compensation committee (Liao and Hsu, 2013). Prior studies on overlap membership document that presence of audit committee members on compensation committee affects the reporting quality. Since auditors’ audit risk is affected by reporting quality. The purpose of this paper is to examine how the auditors perceive the overlap of audit and compensation committee members when pricing audit fees.

The author use a sample from 2007 to 2012 and run an OLS regression.

The author find a negative association between overlap membership and audit fees. The results are robust after controlling for selection bias, alternate measurement of overlap membership, and an alternate pre- and post-overlap membership test. Additional tests show that the negative relationship between overlap membership and audit fees is explained by lower audit risk and not by lower brand premium of non-Big4 auditors and that the benefit of overlapping membership increases when the audit committee size is large.

The findings suggest that firms with large audit committee can improve their reporting and lower their audit fees by having audit committee members on compensation committee.

The findings contribute to the literature on the consequences of overlap membership and on the ongoing debate about the extent that common membership enhances audit committee monitoring. It also adds to the limited literature on audit committee and audit pricing.

In a risk analysis system, different underlying indices often play different roles in identifying the risk scale of the total target in a system, so a concept of discriminatory weight is introduced first. With the help of discriminatory weight and membership functions, a new method for information security risk analysis is proposed. The purpose of this paper is to discuss the above issues.

First, a concept of discriminatory weight is introduced. Second, with the help of fuzzy sets, risk scales are captured in terms of fuzzy sets (namely their membership functions). Third, a new risk analysis method involving discriminatory weights is proposed to realize a transformation from the membership degrees of the underlying indices to the membership degrees of the total target. At last, an example of information security risk analysis shows the effectiveness and feasibleness of the new method.

The new method generalizes the weighted-average method. The comparative analysis done with respect to other two methods show that the proposed method exhibits higher classification accuracy. Therefore, the proposed method can be applied to other risk analysis system with a hierarchial.

This paper proposes a new method for information security risk analysis with the help of membership functions and the concept of discriminatory weight. The new method generalizes the weighted-average method. Comparative analysis done with respect to other two methods show that the proposed method exhibits higher classification accuracy in E-government information security system. What is more, the proposed method can be applied to other risk analysis system with a hierarchial.

The purpose of this paper is to evaluate the response of members to a rebranding strategy implemented by a member‐owned organisation. More specifically, the authors examine the impact of rebranding awareness and attitude towards rebranding on the members' perceived value of their memberships, their satisfaction and, subsequently, their commitment to the organisation.

The research employed in‐depth interviews followed by a quantitative survey. Data were collected online from 264 current members of Dogs SA and data analysis employed SEM principles.

Findings demonstrate that the members' awareness of a rebranding attempt can significantly enhance perceived membership value, leading to increased levels of satisfaction. With both perceived value and satisfaction antecedents of membership commitment, the importance of such improvements cannot be underestimated.

Despite a high response rate of 88 per cent, only ten per cent of the membership base was included in the initial sample. Limitations relate to the single context, a canine association, and single rebranding attempt examined in this paper. Only three outcome measures were included, namely membership value, satisfaction and commitment.

While non‐profit member‐owned organisations play an increasingly important role in our economic and social environment, participation rates are dropping in many such organisations. If they are to remain viable, the commitment of existing members must be improved. The study provides managers with important insight into a potentially powerful strategy to increase underpin membership dedication by means of satisfaction and enhanced perceived value.

This paper successfully integrates relationship marketing and rebranding literature domains, producing significant implications for non‐profit membership organisations.

Analyses union membership trends in the UK since 1979. Confirms the conventional wisdom that overall there has been a substantial membership leakage from UK trade unions for almost a decade and a half. Summarizes and discusses reasons for this. Goes on to show, however, that this overall trend masks a surprisingly steady and sustained growth of employee membership of “non‐affiliated” unions of professional workers and of staff associations, during the 1980s and early 1990s. Examines this stark contrast between falling membership among highly unionate traditional unions and lowly unionate, “non‐political” employee organizations. Explores the characteristics of the “new moderate unionism” in terms of its membership, size, sectoral, gender and industrial distributions and discusses the future prospects of this remarkably resilient group of employee organizations. Classifies them as “publicsector professional associations” and “privatesector staff associations”. Finally, evaluates the nature and ideologies of the “new moderate unionism” in the context of recent managerial employment strategies.

This qualitative study aims to understand young professional newcomers' experiences of communication processes in membership negotiation in their first workplace after graduation.

Instead of a one-time interview, the participants were contacted five to ten times during the three to ten months, beginning when they entered the workplace. The data were analyzed using a constant comparative method.

Three communication processes during membership negotiation were identified: developing reciprocity, seeking and perceiving acceptance and becoming an active member. To experience membership, newcomers need to achieve acceptance and engage in reciprocal communication in early interaction situations with managers and coworkers.

Only the experiences of newly graduated newcomers were studied. This study illustrates the communication processes and social interaction evolving in membership negotiation during newcomers' entry.

Organizations need to re-evaluate their short orientation programs to support membership negotiations in workplace communication.

By recognizing the communication processes during membership negotiation, the practices of newcomers' entry can be developed to support the membership development.

This study contributes to membership negotiation by showing how newcomers join the flow of membership negotiation through the processes of developing reciprocity, seeking and perceiving acceptance and becoming an active member.

Reviews the literature on trade union membership in OECD countries. After considering the ways in which trade union membership is measured, trends in both membership and density since 1970 are examined. When cross‐sectional determinants are considered, density is found to be unrelated to size of employment in the manufacturing sector and the share of female employment, but it is related to the level of collective bargaining and the size of the public sector. An examination of individual and job‐related characteristics finds membership is higher among males, those with family responsibilities, those with lower occupational status and those with low educational achievements and that job dissatisfaction and left‐wing views are also important. Time‐series studies find that while union growth and decline are linked to the business cycle, with wages, prices and unemployment affecting membership, economic factors are not the sole explanation. Concludes by surveying the causes of union decline since 1980, together with recent error‐correction and cointegration approaches to modelling trade union membership.

In the last monograph an attempt was made at giving a short historical background of the trade union movement; at defining a trade union; at discussing the closed shop and at looking towards its future.

The purpose of this study is to model the consumer journey of admission-based membership services from initial purchase to full-season memberships. Particularly, the study pays attention to customer-owned contacts (purchase behavior) and service-owned contacts (salesperson voice- and text-based communications), to examine longitudinal internal data to determine factors which hinder and propel customers toward full memberships.

On the basis of big data supplied by a National Hockey League team, the study uses three simultaneous equations in modeling to account for potential endogeneity related to the likelihood that sales and service personnel are more likely to contact frequent customers. The longitudinal data allow us to map the customer journey over the course of multiple years, compared to typical cross-section studies.

The findings show that as customers increasingly own committed points of contact, they are prepared to move to the next level – but rarely skip major steps in the relationship journey. The quantity, type and timing of customer contacts by the service firm may hinder or propel the customer down the path to purchase full memberships.

The prevalence of big data among service firms should allow researchers to better understand how consumers respond to contact strategies over time, as well as fluctuations in firm performance. The research adds to the customer journey research stream, while meeting the call of researchers to bridge the gap between service marketing research priorities and current practice.

Sales practices and marketing automation tactics may come at the cost of burning leads and alienating future members. Frequent text-based contacts absent voice-based interactions hinder consumer journey and work against relationship building. Service marketers can learn how to better allocate resources, properly manage and motivate contact strategies and target campaigns to send the right message via the right media at the right time.

This is the first study to map customer journey for admission-based, membership services. The longitudinal approach across multiple years provides a deep understanding of how customers take steps toward loyal membership status, while also pinpointing potential drawbacks of current contact strategies.
