The main purpose of this study is to investigate the factors affecting e-trust perception of tourists using Web-based travel intermediaries (WBTIs). Cognitive and affective attitude components are believed to be important in assessing the e-trust perception of tourists. However, this paper aims to investigate if self-efficacy would be an important predictor for e-trust in the context of WBTIs.

The quantitative research method is used in this study. Data were collected by the survey method from the tourists who visited Istanbul/Turkey and made their bookings via Web-based travel intermediaries. Hierarchical linear regression analysis is used to investigate to which extent age/gender/years of usage, self-efficacy, cognitive and affective components are affecting tourists’ e-trust perception.

According to the study results, self-efficacy, the attitude components, in addition to the demographic variables, predict a significant amount of variance (45%) in e-trust for Web-based travel intermediaries. Besides attitude components, self-efficacy is put forward as significantly important in the perception of e-trust.

The novelty of the current study is that it uses hierarchical regression to test if self-efficacy would be an important predictor for e-trust while examining the effect of various predictive variables in sequential order. Therefore, the relative importance of this e-trust predictor can be evaluated based on how much it contributes to the prediction over and above other important antecedents of e-trust according to the literature. This study provides evidence that the social cognitive theory may be useful in understanding e-trust in online tourist behavior.

Intellectual capital (IC) has been suggested to be a means by which firms develop capabilities that enhance competitive advantage. There is, however, a paucity of empirical research linking IC with innovation in construction firms, leaving the IC–innovation link in such environments unclear. The purpose of this paper is to advance understanding of the relationships between IC components and strategic exploratory and exploitative innovation in construction contractor firms.

The sample comprised 135 management personnel from construction contractor firms in Hong Kong. Data were collected through a questionnaire survey using validated scales in the literature which were subjected to confirmatory factor analysis. Hierarchical linear regression was used to test the hypotheses while partial least squares structural equation modelling was used for post hoc analysis.

Social capital (SC) and organisational capital (OC) each have significant positive linear effects on exploratory and exploitative innovation, while human capital (HC) has no direct linear effect on either innovation type. HC, however, affects both exploratory and exploitative innovation through SC or OC. None of the three IC dimensions has a significant quadratic effect on exploratory or exploitative innovation. The findings suggest that in construction contractor firms increases in the accumulation of SC and OC are associated with proportional increases in exploratory and exploitative innovation.

Despite the growth of studies connecting IC to innovation, the link between IC and exploratory and exploitative innovation has focussed on linear effects in units or on radical innovation outcomes. This study makes a novel contextual contribution by exploring both linear and quadratic effects of IC dimensions on strategic exploratory and exploitative innovation processes in construction contractor firms. The insights contribute to advance knowledge on the relationship between IC and innovation categories in different industrial settings.

Flexibility is one enabler of efficient use of resources and is therefore an antecedent to sustainability. The purpose of this article is to identify supplier flexibility variables in, and related to, the order-to-delivery (OTD) process and categorize them into a framework, followed by empirically exploring the framework.

A perception-based survey was sent to Swedish purchasing managers. 289 responses were received. After descriptive gap analysis, exploratory factor analysis was applied to structure the responses into factors. This formed the basis for hierarchical linear regression analysis, explaining supplier flexibility.

A conceptual framework, specifying supplier flexibility into volume, delivery and information exchange dimensions and relating these dimensions to the OTD process, was developed. Significant negative gaps between actual and demanded volume flexibility and delivery flexibility were identified, while positive gaps were found for information exchange flexibility. The factor analysis revealed three factors. The regression analysis verified that OTD-related information exchange flexibility and OTD-related volume and delivery flexibility explain the variation in OTD-specific flexibility and are important antecedents for supplier flexibility in the OTD process.

A contribution to research is the framework – with defined, related and empirically validated flexibility types.

The study proposes a perception-based way to capture supplier flexibility in the OTD process, which is of practical relevance when evaluating suppliers.

Identifying, conceptualizing and capturing types of supplier flexibility in the OTD process is new related to academic literature. Also the wide empirical study mapping supplier flexibility gaps is unique in its focus.

The aim of this paper is to examine the links between project management process characteristics and project-level and firm-level performance outcomes to test the hypotheses that project management assets being valuable, rare, inimitable and having organizational support leads to competitive advantage.

This paper analyzes data from responses to an online survey by 198 North American Project Management Institute® members. Regression analysis is used to examine the relationship between six factors extracted from an exploratory factor analysis that comprise the three project management asset characteristics – valuable, rare and inimitable, three factors that comprise organizational support for the project management process, and two factors that comprise project management performance outcomes – project-level and firm-level performance.

Organizational support for the project management process, specifically project management integration, was found to significantly contribute to both project-level and firm-level performance. Of the asset factors examined, valuable project management knowledge was found to contribute to project-level and firm-level performance, though information technology (IT) tools did not. Inimitable proprietary tangible assets were found to contribute to both project-level and firm-level performance, and inimitable embedded intangible assets were also found to contribute to firm-level performance. Rare knowledge sharing tools and techniques were found to negatively contribute to project-level performance.

Limitations of this study include sample size, response rate and self-report bias, calling for a larger sample in ongoing research.

This study draws managerial attention to project management assets as sources of competitive advantage, highlighting the need to have organizational support for the project management process through organizational integration, and emphasizing the importance of valuable project management knowledge-based assets and inimitable project management assets that are proprietary and tangible as well as those that are embedded and intangible.

Few papers have applied the resource-based view of the firm to examine project management capabilities as a source of competitive advantage. This paper contributes to the literature on the resource-based view of the firm and to an improved understanding of project management as a source of competitive advantage.

The purpose of this paper is to investigate the relationship between transformational leadership and effort-reward imbalance as well as the moderating role of overcommitment and subjective well-being. In particular, the study focuses on the transformational leadership component individualized consideration and its relationship with effort-reward imbalance.

Using linear hierarchical regression analyses, the authors tested four hypotheses on a broad sample of 229 German employees.

The results confirm the expected relationship between transformational leadership and effort-reward imbalance and that the strongest relationship exists with individualized consideration. However, there is no support for the hypothesized moderating effects.

First, the recruitment of the sample via fora and periodicals may bias the results. Second, the dependent and the independent variables were assessed with the same method, thus facilitating a common method bias. Third, the study underlies a cross-sectional design which does not allow drawing conclusions on causality.

The findings provide implications for leaders by showing that the most effective leadership behaviours are those encompassed by the transformational leadership component individualized consideration when it comes to reducing negative health effects of adverse working conditions. Furthermore, the results suggest that overcommitment plays a major role for employees’ effort-reward imbalance and should thus be addressed by specific training measures.

Researchers have devoted little attention to revealing how effort-reward imbalance can be avoided or reduced by leaders. The study attempts to fill this gap by exploring the relationship between effort-reward imbalance and transformational leadership.

The purpose of this paper is to investigate key contingencies affecting the internationalization of young ventures, and to shed light on early internationalization's implications for organizational survival and growth.

A previously suggested conceptual framework is tested based on a quantitative study of UK firms before explorative analysis takes the analysis further.

Contrary to the model suggested by Sapienza et al. that internationalization is of increasing importance at young ventures' founding stage, no such indications were found in this study. Further statistical tests revealed interesting insights into the relationship between other organizational factors and a young firm's survival and growth prospects.

The empirical results suggest that internationalization is a largely overrated theoretical factor as far as young ventures' short‐term survival and performance are concerned. As internationalization paths differ contingent upon country of origin and other factors, further empirical tests are needed beyond the UK sample.

Empirical tests of previously suggested conceptual frameworks are needed to advance the body of knowledge on successful internationalization. Next to this initial test, further exploratory analysis suggests a refined framework.

Technological uncertainty and technological complexity are key characteristics of new product development (NPD) projects that impose significant information processing requirements on organizations. This paper examines the direct influence of technological uncertainty and technological complexity as well as the indirect influence of work experience on organizational information processing capabilities.

The author used a sample of 166 respondents from the German automotive industry and applied linear hierarchical regression analysis.

The results confirm a negative influence of technological uncertainty and technological complexity on organizational information processing capability. This research also supports a moderating influence of work experience on these relationships.

This research helps to understand the relationship between technological uncertainty, technological complexity and OIPC. It represents a first and different approach to measure these constructs for further empirical studies and provides interesting managerial implications.

This study sought to examine the relation of cultural practices and values with favoritism and nepotism/cronyism. Additionally, this study's purpose was also to examine how trust mediates the relation between culture and favoritism.

Correlations were used for exploratory investigation into the bivariate relations between culture and favoritism and nepotism/cronyism across 97 cultures. Hierarchical linear regression analyses were then conducted to examine the cultural correlates of favoritism and nepotism/cronyism holding all other variables constant. Lastly, partial least squares structural equation modeling was used to examine the mediating role of societal levels of trust.

Bivariate correlations showed that collectivism, familism, uncertainty avoidance, and power distance are positive correlates of both favoritism and nepotism/cronyism. Institutional collectivism, future orientation and trust, on the other hand, were negative correlates of favoritism and nepotism/cronyism. Uncertainty avoidance and trust were key correlates of favoritism while familism and future orientation were key correlates of nepotism/cronyism. Trust fully mediated the relation between culture and favoritism but did not mediate the relation between culture and nepotism/cronyism.

This study adds to the current body of literature on culture and favoritism. Notably, the findings regarding different key cultural correlates with respect to favoritism and nepotism/cronyism provide valuable implications for expanding our understanding of the psychological and social nuances of favoritism. Specifically, favoritism in transactions and interactions with those not bound by social commitment relationships may be explained by beliefs while interactions with those with social relationships (e.g., family and friends) may be explained by preferences.

Globally, iron deficiency is the most common nutritional deficiency and the most common cause of anaemia during pregnancy. To date, there is lack of established studies investigating factors associated with iron status during pregnancy in Malaysia. Therefore, this study aimed to determine the associations of obstetrical characteristics and dietary intakes with iron status among pregnant women attending selected health clinics in Selangor and Kuala Lumpur.

A cross-sectional study was conducted among 436 third-trimester pregnant women aged 18–40 years, from six selected health clinics in Selangor and Kuala Lumpur. Data on obstetrical characteristics were extracted from the antenatal medical records. Dietary intakes were assessed using an adapted semi-quantitative food frequency questionnaire via face-to-face interview. Venous blood samples were collected for the measurement of serum ferritin (SF) using ADVIA Centaur analyser to determine iron status.

Approximately one in four of the pregnant women (25.9%) had iron deficiency, with mean SF of 33.35 ± 25.77µg/l. Factors associated with SF were parity (B = −3.048, p < 0.05), frequency of antenatal care visits (B = 1.456, p < 0.05), haemoglobin (Hb) (B = 3.890, p < 0.05), iron intake (B = 0.010, p < 0.05) and frequency of dietary iron supplementation consumption (B = 3.333, p < 0.05). Hierarchical linear regression analyses revealed that dietary factors were significantly associated with SF, after accounting for the obstetrical characteristics.

Besides obstetrical factors, the findings emphasised the importance of dietary factors on iron status during pregnancy. Nutrition consultation service particularly on the sources of iron intake and compliance towards dietary iron supplementation shall be provided to all pregnant women.

Prior studies of criminal sentencing have largely focused on individual-level predictors of sentencing outcomes. The purpose of this paper is to examine the effects of a variety of theoretically derived community measurements of social threat and disadvantage on the criminal sentencing of convicted felons. This analysis permits an evaluation of whether legal ideals such as equality before the law and policy goals of equal treatment for like offenders are achieved.

The study examines data of individuals sentenced in the state of Florida and community level measurements of racial and ethnic threat and community disadvantage. Hierarchical generalized linear model is used to analyze the effect of these measures on the dichotomous in/out imprisonment variable, and standard hierarchical linear regression analysis is used to model the continuous dependent variable of sentence length.

The results provide support for the racial threat perspective though not for ethnic threat nor community disadvantage. The findings and their implications are discussed in terms of theory, research and policy.

Racial disparity in criminal justice practices is receiving increasing public and policy attention, as evidenced by the growing Black Lives Matter movement. Regarding sentencing, racial disparity remains a major research and policy question. While the current research and theoretical literature on sentencing is not conclusive, it is clear that race matters. As a result, racial disparity in sentencing needs to be a priority in subsequent “transitional criminology” efforts between researchers and policy makers to identify, explain and ultimately predict exactly how race impacts sentencing, and how to reduce it as a consideration from sentencing.

This study contributes to a growing body of literature that examines the social context of punishments by using several community level measurements of threat and disadvantage, while modeling the two-step sentencing outcome of imprisonment and sentence length.
