This paper aims to propose a functional methodology to produce cranial prostheses in polymeric sheet. Within the scope of rapid prototyping technologies, the single-point incremental forming (SPIF) process is used to demonstrate its capabilities to perform customized medical parts.

The methodology starts processing a patient’s computerized axial tomography (CAT) and follows with a computer-aided design and manufacture (CAD/CAM) procedure, which finally permits the successful manufacturing of a customized prosthesis for a specific cranial area.

The formability of a series of polymeric sheets is determined and the most restrictive material among them is selected for the fabrication of a specific partial cranial prosthesis following the required geometry. The final strain state at the outer surface of the prosthesis is analysed, showing the high potential of SPIF in manufacturing individualized cranial prostheses from polymeric sheet.

This paper proposes a complete methodology to design and manufacture polymer customized cranial prostheses from patients’ CATs using the novel SPIF technology. This is an application of a new class of materials to the manufacturing of medical prostheses by SPIF, which to this purpose has been mainly making use of metallic materials so far. Despite the use of polymers to this application is still to be validated from a medical point of view, transparent prostheses can already be of great interest in medical or engineering schools for teaching and research purposes.

Colombia has one of the highest levels of inequality in landholding in the world. This inequality has persisted in spite of numerous state-led land reform efforts, which leads to the question: why has it been so difficult to reverse unequal land distribution in Colombia? To answer this question, the chapter examines the role of the state, non-state armed groups, land inequality, land reform efforts, and a history of violence to reveal the relationship between land, inequality and violence in Colombia. This chapter explores the nature of this relationship to understand Colombia’s enduring inequality and to inform theoretical approaches to statehood and power. Rather than reducing state capacity to common Weberian binary constructions of state and statelessness, I explore how state capacity takes on different forms in different regions of Colombia – analyzing how various actors shape land inequality and violence across the territory. Using a comprehensive longitudinal panel data set of displaced persons, I use a negative binomial regression model to demonstrate how land reform, land inequality, and a history of violence have directly affected current displacement of citizens. I argue that several constellations of powerful social actors have at various points converged to control land, through non-state armed groups, to exert a local form of logistical control outside the scope of the federal state, deeply affecting the dynamics violence across different territories. These groups have subsequently engaged in a land grabbing process that has resulted in a reverse form of land reform – leading to persisting inequality in Colombia.

Hyperinflation is a rare form of macroeconomic crisis that often results from extreme political events, such as revolution or regime change. The 1989–1990 Argentine hyperinflation is puzzling because it occurred in the absence of such an event. Moreover, conventional fiscal mechanisms linking political processes to hyperinflation do not sufficiently explain the Argentine case. Previous theories emphasizing distributional conflict and institutional weakness contain key elements of an explanation of the Argentine hyperinflation but do not capture the range of mechanisms that produced extreme financial instability. This chapter offers an elite theory approach that subsumes elements of these approaches within a broader theory of elite fragmentation, competition, and conflict. Elite fragmentation inhibits collective action in both economic and state elites, resulting in deficits in policymaking capacity. Fragmentation among state policy elites leads to policy volatility and incoherence, while fragmentation among politically mobilized economic elites results in elite stalemates constraining the options of policy elites. These policymaking patterns lead to prolonged delays in the adjustment of unsustainable organizational structures, resulting in explosive forms of crises.

This chapter focuses on the international development plans implemented in Colombia during the regime of Gustavo Rojas Pinilla (1953–1957). It argues that foreign economists and international agencies, such as the World Bank, played a significant role in supporting and strengthening local leaders opposing the regime. By analyzing the creation of the Cauca Valley Corporation in 1955, through the intervention of the former chair of the Tennessee Valley Authority (TVA) David Lilienthal, this study provides two main contributions to the literature on economists and political economy under authoritarian rule. Firstly, it illuminates how local groups mobilized international economists to contrast Rojas. Secondly, it analyses the evolving relationship between World Bank advisors, David Lilienthal, and the regime. After describing the consolidation of political and economic interest groups and their global connections before Rojas coup d’état, it focuses on Rojas’ regime and on how it affected the implementation of the World Bank development started with the General Survey Mission in 1949. In the Cauca Department, local leaders invoked the World Bank and Lilienthal to implement a TVA model in opposition with the central government.

Despite manager’s investments in facilitating knowledge sharing, such as hiring employees with lots of knowledge, knowledge hiding remains prevalent in organizations. It may stem from that less attention has been paid to the relationship between perceived overqualification and knowledge hiding. Drawing on emotion theory, this study aims to build a mediation framework to examine effects of perceived overqualification on knowledge hiding via negative emotion state and moderating role of team positive affective tone.

The paper uses a two-wave survey study among 398 knowledge workers from 106 teams in knowledge-intensive industries and tests the hypotheses by performing a series of hierarchical linear modeling analyzes.

The results show that a negative emotion state mediates the U-shaped relationship between employees’ perceived overqualification and knowledge hiding behavior. Team positive affective tone moderates the U-shaped relationship between negative emotions and employees’ knowledge hiding behavior.

This study extends current knowledge management literature by introducing perceived overqualification as an individual predictor of employees’ knowledge hiding behavior and revealing the both light and dark sides of perceived overqualification on knowledge hiding, as well as its intervening mechanism. The research findings help practitioners to curb such counterproductive behaviors.

This study aims to investigate the outcomes of customers’ co-creation experience in a realistic and routinely performed co-creation setting, a restaurant. To fulfill this purpose, the current study links the branding literature to hospitality research and offers a novel framework by incorporating customers’ co-creation experience, customer brand engagement, emotional brand attachment and customer satisfaction in an integrated research model.

Data were collected from 421 diners at Chinese hotpot restaurants via a self-administered questionnaire. The reliability and convergent and discriminant validities were established through confirmatory factor analysis, and then hypotheses were tested through structural equation modeling.

This study demonstrates that customers’ co-creation experience with a restaurant brand positively impacts customer brand engagement, emotional brand attachment and customer satisfaction. In addition, current study examines these relational paths at the dimensional level by taking the co-creation experience and customer brand engagement as multidimensional constructs. The resulting in-depth investigation reveals that the hedonic, social and economic experience dimensions of co-creation experience positively influence customer satisfaction, emotional brand attachment and customer brand engagement’s buying, referring, influencing and feedback dimensions.

This study helps relationship and brand managers better understand customer experience in co-creation settings and paves the way for managers to devise engagement strategies.

The current study marks an initial attempt to delineate the outcomes of customers’ co-creation experience in a realistic co-creation setting. Furthermore, the study is first of its kind that investigates the relationship of co-creation experience and customer brand engagement at the dimensional level.

External stakeholder risks (ESRs) caused by unfavorable behaviors hinder the success of project portfolios (PPs). However, due to complex project dependency and numerous risk causality in PPs, assessing ESRs is difficult. This research aims to solve this problem by developing an ESR-PP two-layer fuzzy Bayesian network (FBN) model.

A two-layer FBN model for evaluating ESRs with risk causality and project dependency is proposed. The directed acyclic graph (DAG) of an ESR-PP network is first constructed, and the conditional probability tables (CPTs) of the two-layer network are further presented. Next, based on the fuzzy Bayesian network, key variables and the impact of ESRs are assessed and analyzed by using GeNIe2.3. Finally, a numerical example is used to demonstrate and verify the application of the proposed model.

The proposed model is a useable and effective approach for ESR assessment while considering risk causality and project dependency in PPs. The impact of ESRs on PP can be calculated to determine whether to control risk, and the most critical and heavily contributing risks and project(s) in the developed model are identified based on this.

This study extends prior research on PP risk in terms of stakeholders. ESRs that have received limited attention in the past are explored from an interaction perspective in the PP domain. A new two-layer FBN model considering risk causality and project dependency is proposed, which can synthesize different dependencies between projects.

This study aims to represent the initial impact analysis of a human resource development (HRD) intervention – the Center for Human and Organizational Potential (cHOP) – for faculty and staff at an academic medical center in the Midwestern US. cHOP seeks to unleash faculty and staff potential and advance organizational outcomes by fulfilling employees’ basic psychological needs, posited by self-determination theory (SDT, Ryan and Deci, 2000): competence, autonomy and relatedness.

Using Cianciolo and Regehr’s (2019) layered analysis framework as a guide, the authors conducted a program evaluation to analyze, in-depth, the nature and impact of two representative cHOP programs: Accelerate and BOOST. Specifically, the authors examined whether the implementation of these programs was consistent with SDT, as reflected in participants’ reported program experiences (i.e. “Did the intervention, in fact, occur as intended?”). The authors also examined program outcomes and opportunities for improvement based on program participants’ voices (i.e. did the intervention, implemented as intended, work?). Because SDT is a theory of individual motivation, the authors identified a need to evaluate outcomes at the individual level and beyond, broadly exploring what would happened if program participants’ basic psychological needs had been addressed. The aim was to determine the potential downstream consequences of intrinsically motivated faculty and staff, while promoting divergent thinking on program impact and sustainability.

Participants reported experiences suggest that Accelerate and BOOST addressed all three psychological needs and strengthened their intrinsic motivation to advance their leadership and career development and improve the performance of their teams and departments. These outcomes suggest the potential for impact at the individual level and beyond, such as the institution and external, professional societies.

The study assessed two representative programs among cHOP’s many offerings. A comprehensive study of cHOP’s impact, directly linking psychological need fulfillment and organizational impact, is beyond the scope of a single study and requires further research.

The authors suggest expanding scholarly discussions in the HRD and health professions education (HPE) literature to characterize the promise of HRD-HPE partnerships and to account for their impact more fully.

The study contributes to both HRD and HPE scholarship by providing a layered account of academic medical center (AMC) faculty and staff development using an HRD approach; and examining the impact of a theory- and evidence-based novel HRD intervention (i.e. cHOP) at the individual level and beyond in an AMC context.
