Abstract
Long-standing traditions of long-distance collaboration and networking make scholars a good test case for differentiating hype and reality in distributed, networked organizations. Our study of Canadian scholars in the GRAND research networks finds that they function more as connected individuals and less as members of a single bounded work group, often meeting their needs by tapping into diversified, loosely knit networks. Their internet use interpenetrates with in-person contact: the more they use one, the more they use the other. Despite digital networking, local proximity is important for collaboration and seniority for inter-team and interdisciplinary boundary spanning.

Abstract
Social scientists often speculate that both acculturation and socioeconomic status are factors that may explain differences in the body weight between Mexican Americans and whites and between Mexican Americans and Mexican immigrants, yet prior research has not explicitly theorized and tested the pathways that lead both of these upstream factors to contribute to ethnic/nativity disparities in weight. We make this contribution to the literature by developing a conceptual model drawing from Glass and McAtee’s (2006) risk regulation framework. We test this model by analyzing data from the 1999–2012 National Health and Nutrition Examination Survey (NHANES). Our conceptual model treats acculturation and socioeconomic status as risk regulators, or social factors that place individuals in positions where they are at risk for health risk behaviors that negatively influence health outcomes. We specifically argue that acculturation and low socioeconomic status contribute to less healthy diets, lower physical activity, and chronic stress, which then increases the risk of weight gain. We further contend that pathways from ethnicity/nativity and through acculturation and socioeconomic status likely explain disparities in weight gain between Mexican Americans and whites and between Mexican immigrants and whites. Study results largely support our conceptual model and have implications for thinking about solutions for reducing ethnic/nativity disparities in weight.

Abstract
Purpose
The purpose of this paper is to derive the exact analytical expressions for torsion and bending creep of rods with the Norton-Bailey, Garofalo and Naumenko-Altenbach-Gorash constitutive models. These simple constitutive models, for example, the time- and strain-hardening constitutive equations, were based on adaptations for time-varying stress of equally simple models for the secondary creep stage from constant load/stress uniaxial tests where minimum creep rate is constant. The analytical solution is studied for Norton-Bailey and Garofalo laws in uniaxial states of stress.
Design/methodology/approach
The creep component of strain rate is defined by material-specific creep law. In this paper the authors adopt, following the common procedure Betten, an isotropic stress function. The paper derives the expressions for strain rate for uniaxial and shear stress states for the definite representations of stress function. First, in this paper the authors investigate the creep for the total deformation that remains constant in time.
Findings
The exact analytical expressions giving the torque and bending moment as a function of the time were derived.
Research limitations/implications
The material isotropy and homogeneity preimposed. The secondary creep phase is considered.
Practical implications
The results of creep simulation are applied to practically important problem of engineering, namely for simulation of creep and relaxation of helical and disk springs.
Originality/value
The new, closed form solutions with commonly accepted creep models allow a deeper understanding of such a constitutive model's effect on stress and deformation and the implications for high temperature design. The application of the original solutions allows accurate analytic description of creep and relaxation of practically important problems in mechanical engineering. Following the procedure the paper establishes closed form solutions for creep and relaxation in helical, leaf and disk springs.

Abstract
Purpose
This paper aims to assess whether the factor structure of the Psychopathic Processing and Personality Assessment (PAPA) could be confirmed in a large community sample (n = 1,850), comprising three subsamples of adult men (n = 189, 248 and 198) and women (n = 499, 469 and 247). It was predicted that the four-factor solution originally proposed in earlier studies (i.e. dissocial tendencies, emotional detachment, disregard for others, lack of sensitivity to emotion) would be replicated and produce a multi-dimensional structure consistent across sex.
Design/methodology/approach
This study explored the structure of the newly developed PAPA among a non-forensic sample.
Findings
Although exploratory analysis indicated a four-factor solution, the structure was different with “lack of sensitivity to emotion” being replaced by “responsiveness to perceived aggression.” Confirmatory analyses supported this structure among women, yet a three-factor structure was preferred for men that excluded emotional detachment.
Research limitations/implications
This study highlights the importance of attending to sex differences when assessing for psychopathy.
Originality/value
This is the first confirmatory factor analysis completed on the PAPA, with the findings conveying its value when assessing for psychopathic traits among a community sample.

The aim of this paper is to assess the effects of traditional inputs and firms' R&D capital on labour productivity growth.
Abstract
Purpose
The aim of this paper is to assess the effects of traditional inputs and firms' R&D capital on labour productivity growth.
Design/methodology/approach
The study measures the effects of the traditional inputs on firms' productivity growth, through four procedures: OLS in first differences, within group, GMM in first differences and GMM system.
Findings
Whatever the specification considered, the more efficient estimates obtained from the GMM system show a similar effect of the firm's R&D stock upon its labour productivity performance.
Practical implications
The results suggest that physical capital plays a more prominent role for European firms than for US ones, while employees are more productive in the USA.
Originality/value
By presenting some empirical evidence on the effects of R&D on labour productivity, at the firm level, the present study makes two main contributions to the existing literature. First, a unique firm‐level database for European and US firms is used. It is self evident that firms in these countries operate in different economic and institutional settings; as a consequence the results identify some robust common effects concerning the two areas considered (the USA versus Europe) at the micro level. Second, service and manufacturing sectors are merged.

Abstract
Purpose
Peter F. Drucker (1909‐2005) was an influential modern management theorist. This paper, however, aims to challenge his diagnosis and prescriptions on the public sector for over‐simplifying several complex issues and not being sufficiently comprehensive. With the support of the empirical findings of a survey in the government of Hong Kong Special Administrative Region (HKSARG), the authors seek to supplement Drucker's discussion on government and to propose managerial actions for implementing change.
Design/methodology/approach
An e‐mail questionnaire survey of 700 randomly selected government employees in Hong Kong was conducted. Additional information was gathered from senior management to validate the survey results.
Findings
In line with Drucker, HKSARG employees, as a whole, are reluctant to change. But statistical tests show that there are heterogeneous behavioural groups. Specifically, younger and more educated staff are more willing to change. The existence of these groups has both practical and managerial implications for implementing change.
Research limitations/implications
The usable sample is relatively small (n=66).
Practical implications
The government should not be viewed and understood unidirectionally. Management should target the younger and more educated users first to build up sufficient user mass and adopt peer pressure for a more successful level of implementation of IT usage across all staff. Job rotation and flexible entry and exit options are worth considering, too.
Originality/value
This research validates empirically the nature of HKSARG. It demonstrates that researchers' challenges to Drucker's views on government are well founded. More research on the characteristics of the public sector is required for better understanding of the real nature of these large, bureaucratic organisations.

Abstract
Purpose
This study aims to examine the impacts of climate change (CC), measured average annual rainfall, average annual temperature and carbon dioxide (CO2e) on cereal production (CPD) in Bangladesh by using the annual dataset from 1988–2014, with the incorporation of cereal cropped area (CCA), financial development (FD), energy consumption (EC) and rural labor force as important determinants of CPD.
Design/methodology/approach
This study used an auto-regressive distributive lag (ARDL) model and several econometric approaches to validate the long- and short-term cointegration and the causality directions, respectively, of the scrutinized variables.
Findings
Results of the bounds testing approach confirmed the stable long-term connections among the underlying variables. The estimates of the ARDL model indicated that rainfall improves CPD in the short-and long-term. However, CO2e has a significantly negative impact on CPD both in the short-and long-term. Results further showed that temperature has an adverse effect on CPD in the short-term. Among other determinants, CCA, FD and EC have significantly positive impacts on CPD in both cases. The outcomes of Granger causality indicated that a significant two-way causal association is running from all variables to CPD except temperature and rainfall. The connection between CPD and temperature is unidirectional, showing that CPD is influenced by temperature. All other variables also have a valid and significant causal link among each other. Additionally, the findings of variance decomposition suggest that results are robust, and all these factors have a significant influence on CPD in Bangladesh.
Research limitations/implications
These findings have important policy implications for Bangladesh and other developing countries. For instance, introduce improved cereal crop varieties, increase CCA and familiarizes agricultural credits through formal institutions on relaxed conditions and on low-interest rates could reduce the CPD’s vulnerability to climate shocks.
Originality/value
To the best of the authors’ knowledge, this study is the first attempt to examine the short- and long-term impacts of CC on CPD in Bangladesh over 1988–2014. The authors used various econometrics techniques, including the ARDL approach, the Granger causality test based on the vector error correction model framework and the variance decomposition method.
