Age-related lifecycles - Purpose variations

By describing and discussing Australian data on outbound tourism, this paper investigates the bimodal (double peaked) lifecycle pattern predicted and observed in the literature. These theories are primarily based on demand for holiday tourism, but tourists do not just go overseas for this purpose, with visiting friends and relatives, business, convention and conference, employment and educational tourism relevant purposes also. Trips overseas by Australians are split into these groups, enabling the age-related lifecycles of each to be examined separately. Unlike holiday tourism, all other purposes are unimodal, although they vary with respect to the age groups at which they peak and their relative positions.

Effects of slurry rheology on industrial grinding performance

To determine the effect of slurry rheology on industrial grinding performance, 45 surveys were conducted on 16 full-scale grinding mills in five sites. Four operating variables - mill throughput, slurry density, slurry viscosity and feed fines content-were investigated. The rheology of the mill discharge slurries was measured either on-line or off-line, and the data were processed using a standard procedure to obtain a full range of flow curves. Multi-linear regression was employed as a statistical analysis tool to determine whether or not rheological effects exert an influence on industrial grinding, and to assess the influence of the four mill operating conditions on mill performance in terms of the Grinding Index, a criterion describing the overall breakage of particles across the mill. The results show that slurry rheology does influence industrial grinding. The trends of these effects on Grinding Index depend upon the rheological nature of the slurry-whether the slurries are dilatant or pseudoplastic, and whether they exhibit a high or low yield stress. The interpretation of the regression results is discussed, the observed effects are summarised, and the potential for incorporating rheological principles into process control is considered, Guidelines are established to improve industrial grinding operations based on knowledge of the rheological effects. This study confirms some trends in the effect of slurry rheology on grinding reported in the literature, and extends these to a broader understanding of the relationship between slurry properties and rheology, and their effects on industrial milling performance.

An investigation into commitment in non-Western industrial marketing relationships

This paper reports an investigation into the antecedents of commitment in non-Western industrial marketing relationships. The authors draw the antecedents from extant literature and posit that commitment is related to trust (integrity and reliability), communication quality, conflict, and similarity (social, ethnic, and economic). It is further argued that trust mediates the effects of communication, conflict, and similarity on commitment. As an extension, the authors examine the moderating effects of normative contracts (an implicit understanding of roles and responsibilities) on the construct interrelationships. The hypotheses are tested using data collected from approximately 150 industrial marketing relationships sampled from overseas Chinese firms. The results generally support the authors' framework; however, the mediating hypotheses are not supported. There is evidence of systematic differences in the effects of the studied antecedents on commitment and trust. Furthermore, a multigroup analysis provides evidence of significant moderating effects due to contracting mode. The study provides new insights into the theory and practice of industrial marketing.

The validity of publication and citation counts for Sociology and other selected disciplines

The use of bibliometric data is a means of comparing. research productivity and scholarly. impact for individuals, work groups, institutions and nations within and between disciplines. Central to this debate is the notion that disciplines differ in the ways in which,they exchange ideas and disseminate information and therefore have diverse publishing and citation patterns. In this article we use two different approaches to compiling bibliometric data to compare publishing patterns of five different disciplines that encompass Molecular Biology; Administration/Political Science, Psychology,. Philosophy and Sociology/Anthropology. We find that the social sciences differ from each other as well as from the physical sciences in their publication and citation patterns. Further, while the different ways of organizing the data produce somewhat different results, the substantive findings for the general patterning of publications and citations of disciplines are consistent for both data sets. Sociology/Anthropology, when compared with the other disciplines, shows substantial differences across universities.

O discurso e a ação : análise do processo de mudança no sistema de controle gerencial em uma organização industrial brasileira sob a ótica da teoria institucional

O objetivo desse estudo foi investigar o processo de mudança no sistema de controle gerencial (SCG), analisando a alteração das práticas de controle gerencial na estrutura desse sistema, sob a ótica da teoria institucional. A questão de pesquisa é: como ocorre o processo de mudança no SCG em uma organização industrial brasileira? Para tanto, optou-se por uma abordagem qualitativa do tipo descritiva, num estudo de caso único, utilizando como métodos de coleta de dados entrevistas individuais não estruturadas e semiestruturadas com 11 gestores e usuários do SCG, observação não participante e levantamento documental. A coleta dos dados ocorreu entre agosto/2014 e março/2015. Como método de análise e interpretação de dados foram utilizados elementos da análise do discurso (AD). Os principais referenciais teóricos foram os trabalhos de Meyer e Rowan (1977), Dimaggio e Powel (1983, 1991, 2007), Scott (1995, 2008a, 2008b) e Machado-da- Silva e Vizeu (2007) sobre a teoria institucional; Huy (2001), Beekman, Chenhall e Euske (2007) e Machado-da-Silva, Fonseca e Crubellate (2010) referente ao processo de mudança; e Malmi e Brown (2008) e Simons (1995) referente ao SCG; destacando a aplicação empírica dos modelos teóricos de Malmi e Brown (2008), Simons (1995) e Huy (2001). Na análise dos dados, foi identificado o desenho e o uso do SCG, relatando como está transcorrendo a alteração de suas práticas de controle gerencial, identificando os fatores de estímulo e resistência à institucionalização dessas práticas e quais os atores organizacionais que estão atuando como agentes da mudança. Por fim, foram identificados os aspectos discursivos recorrentes que permeiam o discurso da empresa pesquisada, alinhados ao processo de mudança no SCG. Como contribuições, foi demonstrada a influência dos fatores isomórficos na escolha das práticas de controle gerencial, a evidência de que o SCG é socialmente construído, as implicações da centralização do poder e da ausência de estratégias para o SCG, evidências de que o processo de mudança no SCG não é meramente mecânico ou automatizado e ainda, que o discurso da mudança pode permear a organização sem que a ação seja concretizada, revelando um descompasso entre o discurso e a ação
