Abstract
Lung cancer is the leading cause of death worldwide. Physical and chemical agents such as tobacco smoke are the leading cause of various lung cancers. The intrinsic heterogeneity of normal lung tissue may be affected in different ways, giving rise to different types of lung cancers classified as either small‐cell lung cancer (SCLC) or non‐small cell lung cancer (NSCLC). Adenocarcinoma, a NSCLC, accounts for 40 percent of all lung cancer cases and the incidence is increasing worldwide, especially among women. The survival rate and prognosis is poorest for adenocarcinoma. Therefore, diagnosis at the earliest stage (Stage I, localized) is critical for increasing survival rates of those suffering from lung cancer. However, many factors affect early diagnosis including the variable natural growth of tumors plus technological and human factors associated with manipulation of tissue samples and interpretation of results. This article reviews potential problems associated with diagnosing lung cancer and considers future directions of diagnostic technology.

Abstract
Purpose
The purpose of this study was to realize finite element simulation in order to dynamically determine the area of the contact, the contact pressure and the strain energy density (identified as a damage function) for three different activities – normal walking, ascending stairs and descending stairs – that could be considered to define the level of the activity of the patient.
Design/methodology/approach
The finite element model uses a modern contact mechanism that includes friction between the metallic femoral condyles or femoral head (considered rigid) and the tibial polyethylene insert or acetabular cup (considering a non-linear behaviour).
Findings
For all three activities, the finite element analyses were performed, and a damage score was computed. Finally, a cumulative damage score (that accounts for all three activities) was determined, and the areas where the fatigue wear is likely to occur were identified.
Originality/value
A closer look at the distribution of the damage score reveals that the maximum damage is likely to occur not at the contact surface, but in the subsurface.

Abstract
Based on a review of multiple literatures, a comprehensive content domain of essential intercultural competencies for effective global leaders is presented. This domain is then used to guide the development of the Global Competencies Inventory (GCI), a 160-item self-report measure that assesses the degree to which individuals possess the intercultural competencies that are associated with global leader effectiveness. Using sample sizes ranging from several hundred to nearly 9,000 subjects, evidence from several studies is presented showing the GCI to have convergent validity, predictive validity, and freedom from demographic and ethnic subgroup biases. Implications for theory and future research are also discussed.

Abstract
The modern workplace contains many physical and interpersonal hazards to employee physical and psychological health/well-being. This chapter integrates the literatures on occupational safety (i.e., accidents and injuries) and mistreatment (physical violence and psychological abuse). A model is provided linking environmental (climate and leadership), individual differences (demographics and personality), motivation, behavior, and outcomes. It notes that some of the same variables have been linked to both safety and mistreatment, such as safety climate, mistreatment climate, conscientiousness, and emotional stability.

Abstract
We know a great deal today about the impact of transformational leaders, their actions, typical behaviors and their ways of influencing others (Bass, 1985, 1999a, b; Bass & Avolio, 1990). However, we know relatively little about the psychological substructure, the internal world of these leaders, namely who they are and how they developed this way. These aspects were raised earlier in Bass’s early work (Bass, 1985) but have received little attention so far (Bass, 1998; Judge & Bono, 2000). We argue that the internal world of a transformational leader is characterized by a motivation to lead, leadership self-efficacy, motivation and capacity to relate to others in a pro-social way, optimism and openness to new experiences and viewpoints of others. We further argue that the origins of the ability and motivation to be a transformational leader lie in childhood experiences, and that the development of this ability and motivation can be understood and conceptualized by means of major developmental theories such as attachment theory (Bowlby, 1969, 1973, 1977, 1988). On the basis of these theories, we suggest a researchable conceptual framework for characterization of the internal world and the development of transformational leaders.

Abstract
Decision-making in human resources management is done at both the micro and macro level of organizations. Unfortunately, the decisions at each level are often executed without consideration of the other, and current theory reflects this issue. In response to a call for integration of micro- and macro-level processes by Huselid and Becker (2011), we review the extant literature on strategic human resources and high-performance work systems to provide recommendations for both research and practice. We aimed to contribute to the literature by proposing the incorporation of the situation awareness literature into the high-performance work systems framework to encourage the alignment of human resources efforts. In addition, we provide practical recommendations for integrating situation awareness and strategic decision-making. We discuss a process for the employment of situation awareness in organizations that might not only streamline human resources management but also result in more effective decisions. Additional considerations include implications for teams, boundary conditions (e.g., individual differences), and measurement.

Abstract
The study investigated the relationship of career instrumental and expressive intra‐organizational network resources with extrinsic and intrinsic career success and with the Big‐Five of personality in a sample of 264 white‐collar workers. Total network resources were associated with extrinsic and intrinsic career success above the contribution of human capital, demographics and mentoring received. And instrumental network resources contributed more strongly than expressive network resources to extrinsic career success. Furthermore, instrumental network resources emerged as important for intrinsic evaluations of hierarchical and interpersonal career success while expressive network resources emerged as important for intrinsic evaluations of job and interpersonal career success. There was limited support for the influence of personality on the accumulation of network resources. As hypothesized, conscientiousness was negatively associated with instrumental network resources; however, extra‐version, openness and agreeableness failed to make significant contributions to network resources over and above the contribution of human capital and demographics. The implications of the findings for individual career tactics and for organizational practices are discussed and the limitations of the study are considered along with directions for future research.

Abstract
Research examining the relation of personality to conflict resolution strategy has yet to incorporate the dominant, contemporary view of personality, the five‐factor model (FFM). The use of broad traits (domains), to represent personality, although parsimonious, ignores information contained in narrow personality facets, masks important conceptual relations with various strategies, and has produced inconsistent results. The present study demonstrates that narrow, rather than broad, FFM traits consistently explain greater variance in strategy, and account for significant variance when FFM domain scores appear unrelated to the criterion. These effects are shown to result from the unbinding of criterion‐related from criterion‐unrelated facet scores that are otherwise aggregated into broad domains.
