Abstract

Purpose

This paper sets out to summarize the current research, development, and integration of a hybrid process to produce high‐temperature metallic materials. It seeks to present the issues and solutions, including the understanding of the direct laser deposition process, and automated process planning.

Design/methodology/approach

Research in simulation and modeling, process development, integration, and actual part building for hybrid processing are discussed.

Findings

Coupling additive and subtractive processes into a single workstation, the integrated process, or hybrid process, can produce metal parts with machining accuracy and surface finish. Therefore, the hybrid process is potentially a very competitive process to fabricate metallic structures.

Originality/value

Rapid prototyping technology has been of interest to various industries that are looking for a process to produce/build a part directly from a CAD model in a short time. Among them, the direct laser deposition process is one of the few processes which directly manufacture a fully dense metal part without intermediate steps. Presented in this paper is the research, development, and system integration to resolve the challenges of the direct metal deposition process including building overhang structures, producing precision surfaces, and making parts with complex structures.

Abstract

Purpose

This study aims to collect real-time, in situ data from polymer melt extrusion (ME) 3D printing and use only the collected data to non-destructively identify printed parts that contain defects.

Design/methodology/approach

A set of sensors was created to collect real-time, in situ data from polymer ME 3D printing. A variance analysis was completed to identify an “acceptable” range for filament diameter on a popular desktop 3D printer. These data were used as the basis of a quality evaluation process to non-destructively identify spatial regions of printed parts in multi-part builds that contain defects.

Findings

Anomalous parts were correctly identified non-destructively using only in situ collected data.

Research limitations/implications

This methodology was developed by varying the filament diameter, one of the most common reasons for print failure in ME. Numerous other printing parameters are known to create faults in melt extruded parts, and this methodology can be extended to analyze other parameters.

Originality/value

To the best of the authors’ knowledge, this is the first report of a non-destructive evaluation of 3D-printed part quality using only in situ data in ME. The value is in improving part quality and reliability in ME, thereby reducing 3D printing part errors, plastic waste and the associated cost of time and material.

Abstract

Purpose

The purpose of this paper is to identify the key parameters that control the bonding formation of foils by the ultrasonic consolidation (UC) process and to build the correlations among process operating conditions and key control parameters through the concept of “process map”.

Design/methodology/approach

The concept of “process map” is proposed based on the diffusion bonding mechanism for the UC process, and numerical simulations have been applied to the UC process to predict peak temperature and plastic strain at the contact interface by considering a wide range of process operating conditions.

Findings

This map reveals that the formation of bonding among foils by the UC process requires a good match between temperature and plastic deformation at the contact interface. This limits the process operating window to a narrow region in the strain – temperature coordinate system.

Originality/value

This work has identified the underlying mechanism for bonding formation and the key control parameters of the UC process. The concept of “process map” for the UC process was developed, which allows the process optimization through two critical process control parameters of temperature and plastic strain at the contact interface instead of five operating conditions.

Abstract

Graduate students of the University of New England (U.N.E.) during the period 1970–1984 wrote one hundred dissertations on morale in a wide variety of educational institutions. The Staff Morale Questionnaire (S.M.Q.) developed and progressively refined at U.N.E. was extensively used in these and other studies in Australia. The project's greatest value lay in the way it enabled external (i.e. off‐campus) students to develop their academic critical abilities in a guided research effort, and in the ripple effect which has enabled numerous administrators in Australian schools to gain some sensitisation to and understanding of the importance of organisational morale.

Abstract

An attempt is made to relate a morale model developed by Stogdill to the three factors identified in 1972 by Smith, Bonnett and Smith and recently confirmed by Williams and Lane. Morale is perceived as being at least a three‐dimensional group output which, like productivity, contributes to individual inputs, expectations, interactions and performance. It is suggested that the intervening variables of leadership, purpose, task, and role perceptions may cause changes in output without any change in individual inputs at a given time. Morale surveys are pertinent to a specific place and specific time: they do not readily lend themselves to prediction.

Abstract

Purpose

The purpose of this paper is: to explain the relative influence of attitude, subjective norm, and perceived behavioral control on purchase intention of the 2010 FIFA World Cup sponsored products; and to compare the purchase intention of American and Korean spectators toward sponsoring products of the 2010 FIFA World Cup. The structural equation modeling (SEM) revealed that subjective norm and perceived behavioral control were predictors of purchase intention. Further, multiple group analysis revealed that the path coefficient between subjective norm and purchase intention for the two groups was significantly different.

Design/methodology/approach

A self-administered questionnaire was developed to measure the four constructs of the theory of planned behavior (TBP) as well as demographic information. Upon completion of the psychometric properties test of the TPB, a SEM was conducted to examine the proposed hypotheses. The same fit indices as with the measurement model were adopted to evaluate the model fit. Finally, a multi-group analysis was conducted to examine if the proposed relationships are different based on nationality (American vs Korean samples). A comparison of χ2 value between unconstrained and constrained models was employed to assess whether the two groups are statistically different.

Findings

SEM revealed that subjective norm and perceived behavioral control were predictors of purchase intention. In this study, a multi-group analysis was conducted to examine if the proposed relationships in our model are different based on nationality. As a result, we found that two groups (i.e. American vs Korean) exhibited notable differences in subjective norms in determining purchase intentions of the 2010 FIFA World Cup sponsored products.

Originality/value

Sponsors for mega sporting events, like the FIFA World Cup, must develop global marketing plans that appeal to worldwide audiences. Sport marketers, therefore, need cross-cultural marketing analysis on equivalence and bias so that they better understand how spectators from different cultures behave after consuming the same event. Thus, application of the TPB in cross-cultural studies aimed at understanding consumer intention after spectating the FIFA World Cup would provide marketers with valuable information for the formation of global marketing strategies.

Abstract

Purpose

The aim of this paper is to examine the early history of restaurants, as invented in Paris around 1766, deciding whether a market orientation ruled out genuine hospitality.

Design/methodology/approach

Contemporary accounts, such as Brillat‐Savarin's section “On Restaurateurs” in The Physiology of Taste in 1825, are considered against a definition of hospitality as a household's provision of care for non‐members.

Findings

The restaurateurs' innovation was selling individualized meals within the emerging consumer market. While Brillat‐Savarin recognized the commercial cynicism of even such brilliant exponents as Antoine Beauvilliers, their enterprises were hospitable to the extent that, emerging from domestic households, they were directed principally at meal‐making rather than money‐making. Highly “McDonaldized” corporations, whose primary purpose is profit, are a largely twentieth‐century development.

Research limitations/implications

Defining hospitality as the provision of care by households to outsiders is a common sense approach that, nonetheless, provides an alternative to the usual characterizations of hospitality, based on ethics, personality, performance or industry.

Social implications

Owner‐operated businesses are more likely to provide hospitality, certainly as traditionally understood, than corporations.

Originality/value

Since eighteenth‐century France, restaurants have only become more important, and the use of the household definition contributes to their better understanding, both historically and conceptually. The definition should have wide applicability.

Abstract

Purpose

This preliminary study aims to investigate and describe aggression-supportive normative beliefs among patients of a high-secure hospital.

Design/methodology/approach

Therapy data from a sample of high-secure forensic hospital patients (N = 11) who had participated in Life Minus Violence-Enhanced, a long-term violence therapy, was examined using interpretative phenomenological analysis (IPA). During therapy, cognitions linked to past incidences of aggression were explored using aggression choice chains.

Findings

IPA was applied to data generated through this process to examine the presence and nature of normative beliefs reported, identifying seven themes: rules for aggressive behaviour; use of violence to obtain revenge; processing emotions with violence; surviving in a threatening world; do not become a victim; using violence to maintain status; and prosocial beliefs.

Originality/value

Findings demonstrate that forensic patients have specific aggression-supportive normative beliefs, which may be malleable. Limitations and implications are discussed.

Abstract

Purpose

The purpose of this paper is to draw on organizational psychology, innovation and knowledge management literatures to investigate the impact of a nurse’s person-organization (P-O) fit on his/her innovative work behavior (IWB). Furthermore, in order to understand the psychological mechanisms surrounding this relationship, the authors examine the mediating role of psychological empowerment and the moderating role of knowledge sharing behavior.

Design/methodology/approach

Data were collected from 441 nurses and 73 doctors through structured questionnaires from four public sector hospitals in Thailand.

Findings

Results of the study indicate that nurse’s P-O fit is positively related to both self (nurse) and doctor’s ratings of innovative behaviors and that psychological empowerment mediates this relationship. These results imply that a nurse’s perception of value congruence impacts his/her perception about feeling of empowerment, which in turn helps in engaging him/her into acts of innovativeness more often. The results also show that the relationship between P-O fit and IWB is stronger among nurses who frequently share their best practices and mistakes with co-workers.

Originality/value

Employee involvement in innovative work is of crucial importance for organization’s competitiveness, especially in the nursing profession. The compatibility between personal and organizational values is a vital ingredient of our personal, social and professional worlds. Although research has identified some antecedents of nurses’ IWB, it is unclear how P-O fit influence nurses’ IWB. Nurses with stronger value congruence when empowered psychologically may respond more effectively to display IWBs in current dynamic and challenging public health care work environments.
