The purpose of this study is to investigate the effects of the cementite morphology on the hydrogen trapping behavior in low-alloy pipeline steel.

In this study, the hydrogen trapping behavior in low-alloy pipeline steel was quantitatively studied by a combination of microstructural observations, electrochemical hydrogen permeation experiments and thermal desorption spectroscopy (TDS) analyses.

P-1 and P-2 steels are two samples with different microstructures. The morphology of cementite precipitates in the P-1 and P-2 steels was different. Lamellar cementite is present in P-2 steel and only granular cementite in P-1 steel, which led to a better irreversible hydrogen trapping ability of P-2 steel, which was confirmed by subsequent hydrogen permeation and TDS experiments.

The study of these deep hydrogen trap sites is helpful in improving the hydrogen embrittlement resistance of low-alloy pipeline steels.

This chapter explores the phenomenon of organizational resilience. A comprehensive model was advanced and tested while utilizing a quantitative study conducted in the education system in Israel with 98 schools, involving 1,132 educators. Statistical analysis based on structural equation modeling revealed significant relationships between three antecedents (social capital, team empowerment, goal interdependence) and organizational resilience. In addition, a positive significant relationship was found between organizational resilience and organizational functioning in crisis. Organizational resilience was found to be a mediator between three of the antecedents (social capital, team empowerment, goal interdependence) and organizational functioning in crisis. Furthermore, organizational functioning in crisis was found to mediate the relationship between organizational resilience and organizational innovation. Implications for policymakers, managers, and change leaders in organizations are discussed.

Organization development is often mourned as stagnant or perhaps dead, but most of these declarations seem to be insular, being supported primarily by anecdotal or survey research among organization development scholars and practitioners. This exploratory study seeks a more objective understanding of the state of organization development by examining big data from the social media platform Twitter. Drawn from over 5.7 million tweets extracted through Twitter's Application Program Interface (API) during 2 months in 2018, this research approaches the state of organization development through a quantitative, abductive study utilizing social network analyses. Organization development is examined through its characteristics as a social network on Twitter and how it relates to and interacts with other familial networks from management and organization studies. Findings show that organization development is relatively inactive as a social network on Twitter, as compared to other familial networks, and the relationships between the organization development network and these familial networks tend to be ones of inequality. Organization development references familial networks much more than any of the familial networks reference organization development. This inequality in social media presence is particularly surprising since several of these familial networks were founded from the field and principles of organization development. We locate organization development's generalist status, as compared to familial networks' specialist status, as generating this interaction disparity drawing on recent research that suggests specialized fields fare better in times of rapid change compared to generalist fields. We discuss the potential for greater specialization of organization development with a reemphasis on its process philosophy and focus.

The purpose of this chapter is to review how well walking interventions have increased and sustained walking, and to provide suggestions for improving future walking interventions. A scoping review was conducted of walking interventions for adults that emphasised walking as a primary intervention strategy and/or included a walking outcome measure. Interventions conducted at the individual, community, and policy levels between 1990 and 2015 were included, with greater emphasis on recent interventions. Walking tends to increase early in interventions and then gradually declines. Results suggest that increased walking, and environmental-change activities to support walking are more likely to be sustained when they are immediately followed by greater economic benefits/time-savings, social approval, and/or physical/emotional well-being. Adaptive interventions that adjust intervention procedures to match dynamically changing environmental circumstances also hold promise for sustaining increased walking. Interventions that incorporate automated technology, durable built environment changes, and civic engagement, may increase cost-efficiency. Variations in outcome measures, study duration, seasons, participant characteristics, and possible measurement reactivity preclude causal inferences about the differential effectiveness of specific intervention procedures for increasing and sustaining walking. This review synthesises the effects of diverse walking interventions on increasing and sustaining walking over a 25-year period. Suggestions are provided to guide future development of more effective, sustainable walking interventions at the population level.

The presence and practice of individual and organizational humility has the power to enable organizational growth and change. Humility drives behaviors associated with learning and the ability to embrace the value of existing mental models while valuing the insights offered by new perspectives and approaches. This paradox-savvy practice, observed in humble individuals and organizations, allows them to appropriately value what is working about the existing system while simultaneously embracing the need for change. Our research finds humble behaviors emerging within psychologically safe environments that foster an attitude of inquiry, kinship, extraordinary collaboration, and professional excellence. Humble behaviors, at every organizational level, appear to enhance both individual and group capabilities that drive long term strategic advantage. Five capabilities were identified in our research: diverse networks, shared values, flexibility and adaptability, judgment and decision-making, and organizational learning. We bring these concepts to life by synthesizing established and emerging research, as well as diving deeply into an empirical case study that leverages humble practices in order to effectively drive organizational change. We argue that humility can impact organizing at all levels (individuals, leaders, followers, teams, executives, and organizations) and in so doing create the conditions in which sustainable organizational change can flourish.

Contextual factors play a vital role in employee mistreatment. This chapter deals with the definition and scope of contextual factors, including a distinction between the objective environment and its idiosyncratic perception by employees. Several mechanisms are offered to explain the effects of context on mistreatment, including the stressor–strain framework, interaction with personal characteristics, and also mistreatment acting as a stressor. The framework suggested in this chapter uses levels of analysis, and proposes that the objective environment (group level variables) is perceived at the individual level, which consequently leads to both perpetrated and received mistreatment. Those same objective environment variables also have a direct effect on mistreatment, as well as a moderating role in the relationship between individually perceived context and mistreatment. Furthermore, there is some evidence that mistreatment acts as a contextual variable in and of itself, with perpetrators, victims, and bystanders perceiving mistreatment in their workplace and reporting higher levels of stressors and strains. Finally, we outline the need for more longitudinal, multi-level studies to clearly discern the role of context in employee mistreatment.

This chapter reviews and integrates recent research on curiosity. We discuss potential costs and benefits of curiosity, both hedonic and motivational. In particular, we examine the Pandora effect, the teasing effect, and the motivating-uncertainty effect.

Developing residential units is crucial in the socio-economic development of a country. The investor faces not only uncertain transaction price (price risk), but also uncertainties about the marketing period risk. Predicting when the incurred money is being realized is difficult because of the imperfect nature of the real estate market. Thus, the purpose of this study is to analyze the variables that explain the time on the market (TOM) of housing units, identifying the relationships in-between and the effects on TOM of residential properties.

Following a multi-stage sampling process, a random sample of 120 housing units was selected. Data were collected using a self-administered questionnaire. The questionnaire contained 57 variables that can affect TOM. Semi-structured interviews were conducted to confirm some of the data and information on residential units from the developers. Direct observations were conducted to verify certain physical attributes and, finally, they were comprehensively analyzed using quantitative analysis techniques in SPSS 16.0 Statistical package.

Results confirmed that lesser advertising prices, attractive environment, proximity to the city center and proper shape of lands reduce the TOM. Similarly, higher prices, longer distance to the city center and irregular shape of land increase the TOM. The results strengthen the necessity of a comfortable environment appropriate to live, probably with greenery or water bodies, which is a key influential factor that reduces the TOM in Sri Lanka.

wIn the Sri Lankan context, there are few contributions to the real estate literature in this regard. Many scholars have concentrated on physical and economic characteristics, whereas this research adds the environmental factors. Therefore, this research makes a significant contribution to the body of knowledge in this area, as it puts more attention on including several variables, as well as newly introduced variables as determinants. Consumers can apply the research findings to assess the relative importance of housing attributes and services which they perceive most valuable, and then to make their purchase decisions. The findings also contribute to the investigations of the behavior of housing attributes and enable knowing as to what factors are to be promoted and what to be omitted to gain a shorter TOM.
