Abstract

Purpose

The aim of this review study is to present useful and practical expressions to compute the design vertical actions on load-bearing columns/walls of typical building structures on the basis of EN 1991: Eurocode 1.

Design/methodology/approach

It is derived by a typical case in which wind actions, snow actions and permanents actions are loading a roof construction. The results are finally used to calculate the loading on columns/walls. Both ultimate limit state and serviceability limit state are considered.

Findings

From an instructive point of view, the advantage of this method is that it is simplified, general, not time-consuming, and it can be standardised to typical building structures.

Research limitations/implications

A number of example applications are introduced to illustrate the calculation procedure.

Practical implications

From an educational point of view, this problem is of interest to civil engineering students because the reviewed method is not cumbersome or time-consuming.

Social implications

From an engineering educational point of view, this problem is of interest to civil engineering students because the reviewed method is not cumbersome or time-consuming.

Originality/value

New formulated expressions to calculate the loadings on structural membranes based on Eurocode are presented.

Abstract

Purpose

The purpose of this paper is to provide an overview of structural design code development in Mexico, as an example of how code evolution has taken place in many countries, and to discuss the challenges faced in improving code compliance and reducing vulnerability.

Design/methodology/approach

All building codes for Mexico City (1920‐2004) and current codes in Mexico were analyzed and compared in terms of their scope and contents. Emphasis is placed on understanding how design requirements, professional liabilities and overall performance requirements have evolved.

Findings

Structural codes have become more refined and complex, including at each revision the current state‐of‐the‐art knowledge. However, code compliance and code misinterpretation are prevalent, mainly because users are not familiar with the concepts and technologies involved. Also, it is stated that government authorities lack the technical capacity to identify code misinterpretations. Finally, it is stated that, for non‐engineered construction guidelines, other educational sources are needed in lieu of merely enforcing codes.

Research limitations/implications

Systematic research aimed at assessing the level of code compliance is needed.

Practical implications

A valuable source of changes and challenges in code implementation and compliance for students and practitioners is provided.

Originality/value

This paper summarizes information on the evolution of Mexican structural codes and offers a critique of the challenges and need for improving code implementation and reducing building vulnerability.

Abstract

Purpose

The purpose of this paper is to establish an understanding of what projectification means, how projectification is driven forward, as well as what the consequences of projectification are in an European Union (EU) context, and in the public sector in general.

Design/methodology/approach

The research methods consist of a literature review as well as a meta-analysis of key EU policy documents related to the functioning of regional development and projects. The paper shows that structural developments brought forth by a projectification in a public sector context have significant consequences.

Findings

Without contextually sensitive interlinking mechanisms between temporary and permanent structures projects risk losing their flexible and innovative qualities, and may fragment the ability of permanent organisations for maintaining coordination and continuity. The findings suggests that the proximity of permanent organisations, the discretion of entrepreneurship, the political priority of the task, the inclusion of competencies and interests, and the quality of transfer mechanisms are essential variables in explaining the outcome of temporary organisations in a politico-administrative context.

Research limitations/implications

The paper contributes to the literature on projects in a public sector context and suggests that comparative research on the drivers and consequences of public sector projectification in supranational as well as national contexts is needed.

Practical implications

The increasing requirements for applied project management skills and methods as criteria for project selection in the public sector highlight the importance of a broader theoretical and practical understanding of projectification.

Originality/value

The paper adds a new dimension to the projectification debate by presenting a descriptive and conceptual discussion about the consequences of public sector projectification in an EU context. It complements an existing theory of the temporary organisation and takes the first steps towards a theory applicable to projectification in a public context.

Abstract

Purpose

This research note puts the role of transition back in the center of the temporary organization and lends to understanding the temporary organization as a transitory unit within the permanent organization. The purpose is to reactivate theory development within this field of research and promote a dialog that will point to a possible way forward.

Design/methodology/approach

An intra‐organizational perspective is taken. Backgrounds of the two theories are covered and then the temporary organization as a transitory unit, and the role of transition are addressed. One basic transformation is made in the theory of the temporary organization and then the model superposed on the behavioral theory of the firm.

Findings

In total, four things were achieved. First, the conceptualization of temporary organization was simplified – five variables have been reduced to four in eliminating “action” as an element of description. Second, the conceptualization was extended to include constructs of the permanent organization. Third, the theory was strengthened by providing an extended framework that potentially could be examined to check observations against theory. Finally, some directions were suggested for future theory development to take.

Research limitations/implications

The research note is conceptual, so applicability depends upon the nature of the particular organization to which it is applied.

Originality/value

Although the paper is conceptual, the authors believe that the approach can be used to understand the interrelatedness of the temporary and permanent organization and to promote a dialog within this field of research – a dialog that hopefully will reactivate theory development.

Abstract

Purpose

This paper aims to analyze the influence of externalization in the workforce on creating a work context that supports innovation and the moderation of this relationship by different contextual variables.

Design/methodology/approach

These relationships were studied using a sample of 249 workers from five firms. Hierarchical regression analysis was used to contrast the hypotheses.

Findings

The results of the study indicate that externalization affects the permanent worker's orientation to innovation negatively and that this relationship is moderated by contextual variables such as group potency and monitoring.

Originality/value

The aim of this paper is to stimulate new lines of research on externalization and orientation to innovation and their repercussions for the firm.

Abstract

The assignment of targets to instruments in developing countries cannot satisfactorily follow any simple universal rule. Which approach is appropriate is influenced by whether the economy is dominated by primary exports, by the importance of the domestic bond market and bank credit, by the extent of existing restriction in foreign exchange and financial markets, by the presence or absence of persistent high inflation, and by the existence or non‐existence of an active international market in the country's currency. Eighteen observations and maxims on stabilisation policy are tentatively drawn (pp. 64–8) from the material reviewed, and the maxims are partly summarised (pp. 69–71) in a schematic assignment, with variations, of targets to instruments.

Abstract

Purpose

The purpose of this paper is to attempt to integrate manufacturing system analysis to obtain system‐wide optimized solutions and to increase the level of comprehensiveness of the manufacturing system modelling and to develop method of characterization of manufacturing systems based on its structure.

Design/methodology/approach

Elements constituting the manufacturing plant and the interactions between them have been identified through a literature survey and have been represented by graph‐based model. The matrix models and the variable permanent function models are developed for carrying out decomposition, characterization and the total analysis.

Findings

Structural patterns and combination sets of subsystems interacting in various ways have been recognized as capabilities of manufacturing system in different performance dimensions. The permanent function of the manufacturing system matrix has been proposed as a systematic technique for structural analysis of manufacturing system. Also, the terms of permanent multinomial characterize the manufacturing systems uniquely and are highly useful for computational storage, retrieval, communication as well as analysis of the structural information of manufacturing system.

Research limitations/implications

The structure‐based characterization technique developed has the potential of aiding the ongoing research activities in the field of benchmarking, and business process reengineering. The graph theory‐based methodology will serve as a framework to develop composite performance measures building on the performance measures of the individual elements of the manufacturing system graph in various dimensions.

Practical implications

Through the use of proposed methodology, a manufacturing manager will be able to make better informed decisions towards organizational efforts of improving the productivity and speed. For aiding several decisions, different “what‐if” scenarios may be generated with several structural modifications.

Originality/value

This graph theory‐based methodology is a novel mechanism to seamlessly integrate manufacturing system giving way to system wide optimization. The paper is an attempt to address the need for comprehensive and integrated analysis of the manufacturing system.

Abstract

Traditional employment practices since the Second World War had usually ensured job security for a company’s workforce. However, the increasingly competitive environment and the restructuring of companies in the 1980s and 1990s have made this practice impossible to continue; therefore, layoffs have become a fact of life for employees in an increasing number of industries. The purpose of this study was to examine attitudes in two employment environments, one in which temporary workers were used to shield permanent employees from layoffs and another in which layoff decisions were made without regard to permanent or temporary status. Specifically, examination was made of the relationships among perceived organizational support (POS), organizational commitment, and intention to quit, and the relative levels of these variables across two environments and the two classes of workers. It was found that, as expected, the relationships among the commitment variables and intention to quit were similar within both environments. Also, as expected, levels of commitment in the “shield” environment were higher than in the “layoff” environment; and POS was higher among temporary employees in the “shield” environment than among permanent workers in the “layoff” environment. A particularly interesting finding was that, in the “layoff” environment, POS among temporary workers was higher than among permanent workers.

Abstract

Purpose

Based on the psychological contract (PC) theory, the purpose of this paper is to identify PC profiles, differentiating between permanent and temporary agency workers (TAW). Moreover, the authors analyzed whether different profiles presented different levels of work engagement.

Design/methodology/approach

A cross-sectional survey data analysis of 2,867 workers, of whom 1,046 were TAW, was analyzed using latent profile analyses.

Findings

Four PC profiles were identified, which differed quantitatively in terms of the overall dimension levels (i.e. balanced, relational and transactional) for PC (i.e. content and fulfillment). ANCOVAs showed that the relational/balanced dominant and transactional dominant profiles presented similar engagement levels for TAW, but for permanent workers the former profile showed higher engagement than the latter. However, for both permanent and TAW the fulfillment profile showed higher engagement than the unfulfillment profile.

Research limitations/implications

The cross-sectional design and the reliance on self-report measures are the limitations of this study, although no causality was claimed and method biases were controlled.

Practical implications

Actions that increase PC fulfillment positively affect the employment relationship of TAW with the client organization.

Originality/value

Few studies have addressed PC typologies. Furthermore, most studies have focussed on temporary workers, but not on TAW and their contract with the client organization. Finally, this study emphasizes the crucial role played by the PC in the levels of work engagement.

Abstract

The primary purpose of this article is to investigate empirically for the US the potential impact of monetary and fiscal policy upon real economic activity using the “St. Louis equation” approach. Only lagged values of the policy variables are included in the estimation to ensure their statistical exogeneity. Hsiao's (1981) multivariate technique is employed to determine the model lag specification. The empirical results suggest that only fiscal policy as measured by high‐employment tax changes can exert a significant lasting impact upon real GNP. Monetary policy, on the other hand, has only a temporary effect on real GNP. The results also show that both monetary and fiscal policy have significant and permanent effects on nominal GNP, the former via its permanent effect on prices and the latter through its permanent effect on real GNP.
